The respiratory system brings air into the lungs, exchanges oxygen and carbon dioxide between the air sacs and bloodstream, and exhales air. It includes the nasal cavity, pharynx, larynx, trachea, bronchial tubes, and lungs. The nasal cavity cleans and conditions air before it reaches the pharynx and larynx, which direct air to the trachea and lungs for gas exchange to occur in the alveoli.
Human respiratory system
Respiration Process which involves taking in oxygen into the cells, using it for releasing energy by burning food and then eliminating the waste products like carbon dioxide and water from the body It is a catabolic process as the food is broken down into simpler form.

Human Respiratory System
The respiratory system is comprised of several organs involved in breathing, including the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles and lungs. Air enters through the nose or mouth and passes through these structures made of cartilage, muscle and mucous membranes to warm, moisten and filter the air before it reaches the lungs. In the lungs, the air flows through increasingly smaller airways called bronchioles until reaching tiny air sacs called alveoli where oxygen and carbon dioxide are exchanged.
Respiratory system
The human respiratory system consists of the nose, pharynx, larynx, trachea, bronchi, lungs, and alveoli. The nose and nasal cavity warm and filter incoming air. The pharynx and larynx are passageways that lead to the trachea, which divides into the left and right bronchi and further branches into bronchioles and alveoli within the lungs. Gas exchange occurs in the alveoli, where oxygen passes into the bloodstream and carbon dioxide passes out.

The respiratory system allows for gas exchange in the body. It begins with the nostrils, where air enters and exits the nasal cavity to be warmed. The pharynx and larynx allow air to pass to the trachea and then bronchi, where air flows into the lungs. The lungs, located in the chest, have lobes and facilitate breathing, respiration, and protection from infection. Inhalation draws oxygen into the lungs through muscle contraction and exhalation removes carbon dioxide as a waste product.
The respiratory system
The respiratory system allows humans to breathe and obtain oxygen while removing carbon dioxide. It includes the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles and lungs. The nasal cavity and mouth allow air to enter, which then passes through the pharynx and larynx before entering the trachea and branching bronchi that lead to the lungs. Within the lungs are clusters of tiny alveoli sacs where the exchange of oxygen and carbon dioxide occurs through thin walls, allowing oxygen to enter the bloodstream and carbon dioxide to be removed.
Respiratory System Anatomy & Physiology
The human respiratory system consists of the upper and lower respiratory tract. The upper tract includes the nose, nasal cavity, sinuses, pharynx and larynx. The lower tract includes the trachea, bronchi, bronchioles and lungs. The nose warms and filters inhaled air. The lungs are the primary organs for gas exchange, extracting oxygen from inhaled air into the bloodstream and releasing carbon dioxide from the bloodstream. Respiration is controlled by respiratory centers in the brainstem which regulate the muscles of breathing.

Respiratory system
The respiratory system is the anatomical system of an organism that introduces respiratory gases to the interior and performs gas exchange. In humans the respiratory system include airways, lungs, and the respiratory muscles. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood. This exchange process occurs in the alveolar region of the lungs
Respiratory system
The respiratory system controls breathing by bringing oxygen into the body through the nose and mouth. Air enters the nasal cavity, where it is warmed and filtered before reaching the pharynx and larynx. The larynx contains the vocal cords and epiglottis, which prevent food from entering the trachea. The trachea divides into bronchi that lead into the lungs, where oxygen diffuses into blood vessels in the alveoli and carbon dioxide diffuses out. Breathing is driven by contractions of the diaphragm during inhalation and its relaxation during exhalation.

Respiratory system
The document summarizes the key structures and functions of the respiratory system. It discusses how air passes through the nasal cavity, pharynx, larynx, trachea, bronchi and bronchioles to reach the alveoli in the lungs. The alveoli are where oxygen and carbon dioxide are exchanged between the air and blood through diffusion. Oxygen is then transported to cells by blood for cellular respiration to produce energy, while carbon dioxide is carried back to the lungs to be exhaled. Breathing is controlled by the diaphragm and rib muscles to inhale and exhale air, regulated by the medulla oblongata in response to carbon dioxide levels.
The Respiratory System
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
Blood vessels: Arteries, Veins and Capillaries
It is one of the circulatory systems. This explains the roles of arteries, veins and capillaries. It also differentiate between the arteries, veins and capillaries. This slide also explained the pulmonary circuit and systemic curcuit. This is an interesting notes and easy to be understand.
Respiratory system ......
The respiratory system allows for gas exchange between the lungs and blood. It consists of the upper respiratory tract including the nose and throat, and the lower respiratory tract including the windpipe, bronchi, and lungs. Respiration involves breathing in oxygen which diffuses into blood vessels in the lungs, and breathing out carbon dioxide which is transported from tissues. The circulatory system then carries oxygen to tissues through blood vessels and removes carbon dioxide to maintain gas exchange throughout the body.
Respiratory system
The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function. The nose, pharynx, larynx, trachea and bronchi all work like a system of pipes through which the air is funnelled down into our lungs. There, in very small air sacs called alveoli, oxygen is brought into the bloodstream and carbon dioxide is pushed from the blood out into the air. When something goes wrong with part of the respiratory system, such as an infection like pneumonia, it makes it harder for us to get the oxygen we need and to get rid of the waste product carbon dioxide. Common respiratory symptoms include breathlessness, cough, and chest pain.
1 respiratory system
The respiratory system functions to oxygenate tissues and remove carbon dioxide through gas exchange. It consists of the upper respiratory tract including the nose and pharynx, and the lower respiratory tract including the larynx, trachea, bronchi, bronchioles and alveoli in the lungs. Oxygen diffuses into the blood in the alveoli while carbon dioxide diffuses out. Breathing is controlled by respiratory centers in the brain and involves inspiration through contraction of the diaphragm and expiration through relaxation.
Respiratory system
The document provides an overview of the respiratory system and control of respiration. It describes the key organs involved, including the nose, pharynx, larynx, trachea, bronchi, lungs and alveoli. It explains the mechanics of breathing through inspiration and expiration. Gas exchange occurs as oxygen passes from the alveoli into the blood and carbon dioxide passes from the blood into the alveoli to be exhaled. The lungs, diaphragm, ribs and autonomic nervous system work together to regulate breathing and ventilation.
Respiratory system
This document provides information about human respiratory system and gas exchange. It discusses that humans require a specialized respiratory surface like lungs due to decreasing surface area to volume ratio with increasing size. The document describes the structure and functioning of lungs including gas exchange in alveoli. It also compares respiration in humans, insects and fish and discusses effects of smoking on lungs.
Anatomy/Physiology Slideshow: The Respiratory System
The respiratory system brings air into the body during breathing. It includes the nose, throat, trachea, and lungs. In the lungs, oxygen from the air is transferred to the bloodstream and distributed to cells throughout the body. The respiratory system has several parts - air enters through the nose and passes through the pharynx and larynx before reaching the trachea. The trachea divides into bronchi that lead into the lungs and branch into smaller bronchioles and alveoli, where oxygen and carbon dioxide are exchanged between the blood and air.
Respiratory system
The document provides information on the respiratory system, including:
1. It describes the major organs of the respiratory system including the nose, pharynx, larynx, trachea, bronchi, and lungs.
2. It explains the processes of external respiration which is the exchange of gases between the lungs and blood, and internal respiration which is the exchange of gases between the blood and cells.
3. It provides details on pulmonary ventilation, the transport of oxygen and carbon dioxide in the blood and tissues, and the role of the respiratory system in regulating blood pH, sound production, thermoregulation and protection from pathogens.
Circulatory System
The circulatory system carries blood and substances throughout the body using the heart and blood vessels. The heart pumps deoxygenated blood to the lungs and oxygenated blood to the rest of the body through arteries. Blood flows through veins back to the heart. It is composed of plasma, red blood cells that carry oxygen, white blood cells that fight disease, and platelets that help blood to clot.

Respiratory system.pptx
Respiratory system is the process of exchange gases oxygen and carbon dioxide in the lungs through the alveoli,in which oxygen inhaled and carbon dioxide exhaled.
Report about Respiratory system
The respiratory system includes the airways, lungs, and blood vessels that work together to oxygenate the blood and remove carbon dioxide. It brings air into the body through the nose and mouth, warms and humidifies it in the sinuses and throat, and delivers it through the windpipe, bronchial tubes, and tiny air sacs in the lungs called alveoli. Here, oxygen passes into the bloodstream and carbon dioxide moves out. Muscles like the diaphragm and bones like the ribs help power breathing.
The Respiratory System
The respiratory system allows us to breathe in oxygen and breathe out carbon dioxide. It has two main zones - the conductive zone which brings air to the lungs through the nose, mouth, throat, trachea and bronchi, and the respiratory zone where gas exchange occurs in tiny air sacs called alveoli surrounded by capillaries. In the alveoli, oxygen passes into the bloodstream and carbon dioxide passes out through the thin walls of the alveoli and capillaries. Diseases and injuries can damage the respiratory system, but exercise and avoiding pollution can help strengthen it.
THE RESPIRATORY SYSTEM.pptx Basic Respiratory system knowledge
Basic knowledge of the respiratory system
Design of artificial respiratory model
Design of Artificial Respiratory Model.. Know about the respiratory system.
The respiratory system consists of the upper respiratory tract (nasal passages), the airway conduction system (larynx, trachea, bronchi, bronchioles and terminal bronchioles), and the lower respiratory tract (alveolar ducts and alveoli). Not all segments of the respiratory system mature at the same pace. The olfactory epithelium matures earliest by PND 7. The lung, however, is not considered mature until PND 21, when alveolarization and microvascular maturation are complete. This chapter will discuss the embryological development (briefly), adult histomorphology, and postnatal histologic development of each major component of the respiratory system.
Respiratory system
The respiratory system is made up of organs involved in the exchange of oxygen and carbon dioxide. It includes the nose, mouth, throat, voice box, windpipe, lungs, and the processes of inhalation and exhalation. The upper respiratory tract comprises the nose, nasal cavity, sinuses and larynx while the lower respiratory tract is made up of the lungs, bronchi and bronchioles, and alveoli. Respiration can be aerobic, using oxygen to produce energy, or anaerobic, producing energy without oxygen. Common respiratory diseases include asthma, bronchitis, pneumonia and tuberculosis.
Human respiration mee
The human respiratory system includes the nose, mouth, pharynx, larynx, trachea, bronchi, bronchioles, and lungs. Air enters through the nose or mouth and is warmed and filtered before passing to the pharynx and trachea. The trachea divides into bronchi that branch into smaller bronchioles and terminate in alveoli in the lungs. The alveoli are surrounded by capillaries where oxygen diffuses into the bloodstream and carbon dioxide diffuses out. Breathing is facilitated by the diaphragm muscle. The respiratory system works to oxygenate the blood and remove carbon dioxide
Gaseous exchange
Gaseous exchange involves the intake of oxygen and exhalation of carbon dioxide through breathing to fulfill the body's requirements. Respiration is the energy releasing process where glucose breaks down with oxygen to provide energy, while breathing is the voluntary physical process of gas exchange. Breathing in humans involves the air passageway which brings air through the nose, pharynx, larynx, trachea, bronchi and bronchioles to the lungs. In the lungs, oxygen diffuses into blood in the alveoli and carbon dioxide diffuses out, with inhalation increasing lung volume through rib and diaphragm movement and exhalation decreasing it. Physical activity increases the rate of breathing to expel more carbon dioxide produced
Respiratory System
The respiratory system is made up of organs that help oxygen enter the body and carbon dioxide leave the bloodstream. Air enters through the nose or mouth and passes through the pharynx and trachea into the lungs. In the lungs, the trachea branches into bronchi which branch further into bronchioles and tiny air sacs called alveoli. The alveoli are surrounded by capillaries and it is at this site that oxygen diffuses into the bloodstream and carbon dioxide diffuses out through very thin cellular walls. The diaphragm and rib muscles help draw air in and out of the lungs during breathing.
Grade 9 - Respiratory system
This document discusses the key parts and functions of the respiratory system. It describes the two phases of breathing - inspiration and expiration. During inspiration, the diaphragm contracts and intercostal muscles raise the ribs, allowing air rich in oxygen to enter the lungs. During expiration, the reverse occurs and air rich in carbon dioxide exits the lungs. The document also outlines respiratory volumes like tidal volume and vital capacity. It explains the role of the nose, pharynx, larynx, trachea, bronchi and lungs in respiration and the process of gas exchange that occurs through external and internal respiration.
Together421
The respiratory system begins with the nose and mouth, where inhaled air is filtered and warmed. The pharynx directs air into the trachea, which divides into bronchi and further branches into bronchioles and alveoli within the lungs. The alveoli are surrounded by capillaries, and their thin walls allow for oxygen to diffuse into the bloodstream and carbon dioxide to diffuse out. The diaphragm and rib muscles aid inhalation and exhalation by expanding and contracting the chest cavity.

After reviewing the respiratory system, it introduces the circulatory system and describes blood flow through the heart, arteries, capillaries, and veins back to the heart. In conclusion, it emphasizes the importance of the circulatory system in sustaining life.
Respiratory system[1]
The respiratory system performs three important functions for the air we breathe: warming it, moistening it, and filtering it. It is made up of the nasal passage, pharynx, epiglottis, larynx, trachea, bronchi, bronchioles, and alveoli. The lungs contain no muscle tissue, so breathing is driven by the diaphragm and intercostal muscles increasing and decreasing the space in the chest cavity. Cellular respiration uses oxygen to extract energy from foods through the breakdown of glucose.
Respiration
The respiratory system allows for gas exchange in humans. Air enters through the nose or mouth and passes through the trachea into the lungs. In the lungs, the bronchi branch into smaller tubes called bronchioles that end in alveoli, which are tiny air sacs where gas exchange occurs. Oxygen from the inhaled air passes into the bloodstream, and carbon dioxide passes from the bloodstream into the alveoli to be exhaled. Breathing is driven by the diaphragm and intercostal muscles contracting and relaxing to expand and contract the lungs and chest.
Chapter 13
The passage describes the respiratory and excretory systems. The respiratory system exchanges oxygen and carbon dioxide through a process called respiration. Oxygen is used in cellular respiration to produce energy, with carbon dioxide as a waste product. The lungs have alveoli with a large surface area for gas exchange between air and blood. The kidneys filter waste like urea from the blood and remove it from the body through urine. Problems of these systems include diseases like pneumonia and emphysema in the lungs, and a buildup of toxins if the excretory system fails.

Here are the answers to your questions:
1) Four polypeptide chains came together to form this antibody.
2) Disulfide bonds are very strong bonds.
3) The variable regions will bind to an antigen.
4) "Variable" means these regions vary between antibodies, while "constant" means these regions are always the same.
5) The structure looks similar to the antigen receptor because antibodies are secreted versions of the B cell's antigen receptor.
Plant adaptation (1)
This document discusses plant adaptations to different environments. It explains that desert plants have developed three main strategies to survive: succulence, drought tolerance, and drought avoidance. Succulent plants store water in their tissues, drought tolerant plants can withstand dry periods without dying by shedding leaves, and drought avoiding plants have a short life cycle to escape dry conditions. The document also discusses carnivorous plants that get nutrients from trapping insects because they grow in nutrient-poor soil, and uses the Venus flytrap as an example of an adapted carnivorous plant.
Plant growth and tropism
This document contains information about an assignment due on Monday to complete a lab report, lists of students assigned to Saturday school sessions, and notes from a biology class on plant growth and tropism. The biology notes discuss key topics like germination, vascular tissue, meristems, phototropism, gravitropism, thigmotropism, and how the plant hormone auxin controls tropism and growth. Processing pieces require students to answer questions applying the concepts and illustrating topics like the types of tropism and how auxin causes phototropism.
Plant reproduction
Flowers produce pollen grains containing male gametes in their anthers. They attract animals to transport pollen between flowers through traits like bright petals and nectar. During pollination, pollen lands on the pistil's stigma and travels to the ovaries where fertilization may occur, forming seeds in fruits that help plants disperse to new locations through various means like wind, water, animals, or being eaten.
Reproductive and endocrine systems
The reproductive system produces gametes and supports embryo development. The female organs are ovaries, fallopian tubes, and uterus, while the male organs are testes, vas deferens, and urethra. Fertilization occurs when an egg and sperm unite to form a zygote. The endocrine system is made up of glands that produce hormones, which travel through the bloodstream to cause changes in distant tissues. Hormones produced include testosterone, estrogen, adrenaline, insulin, glucagon, and growth hormone, which regulate metabolism, stress response, blood sugar levels, growth, and sexual development.
Plant structure
1. Plants have three main parts - roots, stems, and leaves.
2. Roots take in water from the ground, which travels up through tubes called xylem. Xylem carries water to the leaves where it is used for photosynthesis.
3. Leaves make glucose during photosynthesis, which travels down the plant through tubes called phloem. Phloem carries glucose to all cells in the plant.
Feedback loops
Negative feedback loops are cycles that stop the process from continuing once the outcome reaches the desired level. Examples given include checking grades in class and improving performance, becoming hydrated and stopping thirst, and body processes like regulating blood glucose and red blood cell production that maintain homeostasis. Positive feedback loops differ in that the outcome reinforces and strengthens the cycle.
Nervous system
The nervous system has several functions including sending sensory information to the brain, sending commands from the brain to the body, and enabling movement, balance, coordination, reflexes, instincts, thinking, reasoning, memory, emotions, and dreams. It has two main parts - the central nervous system comprising the brain and spinal cord, and the peripheral nervous system comprising nerves in the rest of the body. Neurons are the basic unit of the nervous system, having a cell body, dendrites that receive signals, and an axon that transmits signals. They transmit impulses through electrical signals and neurotransmitters.
Muscular and skeletal systems
This document contains information about the muscular and skeletal systems from a biology class. It includes definitions of the three types of muscle tissue - skeletal, smooth, and cardiac muscle. It also discusses the functions of the skeletal system and the two types of bone tissue. Students are assigned to review the muscular and skeletal systems and complete practice questions and drawings. The exit ticket asks students to identify the type of muscle in different body parts, define key terms, list functions of the skeletal system, and identify where new red blood cells are made.
Excretory system
The excretory system removes waste from the body through urine production and release. It involves the kidneys filtering waste from the blood to produce urine, and the bladder temporarily storing urine until it is released through the urethra. The kidneys regulate salt levels in the blood by controlling how much salt passes into the urine.
Circulatory system
The circulatory system uses the heart, arteries, veins and capillaries to transport blood throughout the body. The blood carries oxygen from the lungs to tissues and removes carbon dioxide from tissues to the lungs. In the tissues, oxygen diffuses from capillaries into cells and carbon dioxide diffuses into capillaries from cells. The circulatory and respiratory systems work together so that oxygen enters the blood in the lungs while carbon dioxide leaves the blood. The circulatory and digestive systems also work together, with capillaries in the intestines allowing nutrient absorption into the bloodstream.
Digestive system
The digestive system has three main functions: 1) Mechanical digestion through chewing and mixing food, 2) Chemical digestion through breaking down molecules in food, and 3) Absorption of nutrients into the bloodstream. Food travels through the mouth, esophagus, stomach, small intestine, large intestine, and rectum, with the small intestine absorbing nutrients through villi, which are tiny finger-like structures containing capillaries that nutrients diffuse into from the intestine.
Enzymes and body organization
1) Enzymes are proteins that catalyze (speed up) chemical reactions in the body. They do this by binding to substrate molecules and facilitating their transformation into product molecules.
2) The body is organized into a hierarchy of levels from smallest to largest: cells, tissues, organs, and organ systems. Cells work together to form tissues, tissues work together to form organs, and organs work together to form organ systems.
3) Enzyme activity can be destroyed by extreme heat, changes in pH, or inhibitor molecules that bind to the active site and prevent substrate binding. Without enzymes, important reactions like digestion could not occur fast enough.
Photosynthesis
Photosynthesis is the process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce oxygen and glucose. It occurs in the chloroplasts within leaf cells. The stomata in leaves allow carbon dioxide to enter and oxygen to exit, while the xylem transports water and the phloem transports glucose. Chemosynthesis is a similar process that some organisms use to produce organic compounds from inorganic ones without sunlight.
Cellular respiration
Cellular respiration is the process by which cells convert glucose and oxygen into carbon dioxide, water, and energy in the form of ATP. It occurs in the mitochondria of eukaryotic cells and is the reverse of photosynthesis. Glucose and oxygen are broken down to produce ATP, water, and carbon dioxide through a series of redox reactions. ATP is a high-energy molecule that cells use to power their metabolic functions.
Macroevolution
1. The document provides definitions and examples of key concepts in evolution, including convergent evolution, divergent evolution, adaptive radiation, extinction, and mass extinction.
2. Convergent evolution is when two species evolve similar traits independently, while divergent evolution is when species evolve differing traits from a common ancestor.
3. Adaptive radiation is a type of divergent evolution where a single ancestral species evolves into many new species adapted to different environments.
4. Extinction is when a species dies out completely, while mass extinction is the sudden extinction of many species, such as the five mass extinctions in Earth's history.
Speciation
This document provides information about speciation and the process of new species forming. It defines key terms like species, speciation, geographic isolation, reproductive isolation, and homologous structures. It explains that speciation occurs when two populations become separated and evolve traits over time that prevent interbreeding, forming new species. Random mutations provide variation and natural selection can make helpful mutations more common between isolated groups.

Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.
