A&p ch 1 review
This document contains a table with columns labeled Terms, Systems, Locations, and Nuts & Bolts containing 100 entries each with anatomical or physiological information. The document provides definitions, parts of the body, systems, and anatomical positions related to human anatomy and physiology.
Anatomical terminology
The document defines anatomical terminology used to describe the body and its regions. It discusses the major body cavities including the cranial, vertebral, thoracic, abdominal, and pelvic cavities. It also describes the serous membranes that line body cavities, including the parietal and visceral layers of the pericardium, pleura, and peritoneum and the spaces they form. Key terms like anterior, posterior, superior, inferior, median, axial and appendicular regions are defined in the context of anatomical orientation and body organization.
Understanding terminology
Medical terminology is comprised of words derived from Greek and Latin. Terms can be broken into three parts: the root, prefix, and suffix. The root identifies the main meaning, condition, or body part. The prefix distinguishes a component or subdivision and advances the root's meaning. The suffix signifies specific features such as circumstances, progression, or intended treatment. Understanding these components and how they are combined to form terms provides the foundation for learning medical terminology.
Scientific method
The scientific method involves asking questions, gathering data through observation and experimentation, analyzing the results, and using evidence to form conclusions. Scientists form hypotheses to explain observations and then design controlled experiments to test these hypotheses. If the data supports the hypothesis, it may become incorporated into a broader scientific theory.
Biology final exam review
The biology final exam review document provides an outline of the key topics and chapters covered on the final exam. It includes karyotypes, genetics, DNA, evolution, environmental issues, and ecosystems.

Key terms and concepts are highlighted for each chapter to help students prepare for the comprehensive biology final exam.
Eco ch6 jeopardy
1) The human population is currently around 7 billion and projected to reach over 9 billion by 2050.
2) Factors driving larger family sizes in India include child labor and care for parents, as well as a preference for male children.
3) China implemented its one-child policy through incentives like better housing for compliant families and providing contraceptives and abortions to control population growth and prevent mass starvation.
Population growth and urbanization
The document discusses issues related to population growth and urbanization. It addresses how human population growth has increased exponentially in the past 200 years due to factors like expanded habitats, improved agriculture, and decreased mortality. If trends continue, the global population is estimated to reach 9 billion by 2050. Urbanization is also increasing, with more people living in urban than rural areas. Urban sprawl poses challenges like loss of land, increased resource use, and economic impacts on central cities. Strategies to slow population growth and curb urban sprawl's negative effects are proposed.
Bacteria jeopardy
Viruses, bacteria, beneficial microbes, disease transmission, and microbial structures are discussed. Key points include: viruses can contain RNA, DNA or both; viruses can be beneficial or pathogenic depending on the virus and host; and bacteria come in cocci, bacilli, and spiral shapes and can be beneficial, pathogenic, or neither. Binary fission is the mode of asexual reproduction for bacteria.
Viruses
Viruses are not considered living organisms because they lack the properties of life such as the ability to reproduce, grow, metabolize, and maintain homeostasis. Viruses have either DNA or RNA surrounded by a protein coat called a capsid. They infect host cells and use the host's cellular machinery to replicate themselves and spread infection. There are several shapes of virus particles including helical, polyhedral, and bacteriophages which have a tail. Viruses can replicate through lytic and lysogenic cycles, sometimes integrating their genetic material into the host. They are able to mutate and evolve, occasionally resulting in more virulent strains. Examples of important human viruses discussed include influenza, HIV, herpes, measles, polio
Bacteria
Bacteria are the oldest living structures on Earth and can be categorized into three kingdoms - Archaebacteria, Eubacteria, and Eukaryotes. Archaebacteria inhabit extreme environments and have cell walls that do not contain peptidoglycan. Eubacteria are more diverse and have cell walls containing peptidoglycan. Bacteria exist in various shapes, groupings, and sizes from 0.5 to 10 microns. They reproduce through binary fission and exchange genetic information through transformation, conjugation, and transduction. Bacteria play important economic roles in nitrogen fixation, nutrient recycling, food production, and medicine.
Genetic disorders ruder
The document appears to be a quiz about various genetic diseases and concepts. It includes questions about sickle cell disease, hemophilia, Huntington's disease, cystic fibrosis, the nucleotides in DNA, sex chromosome disorders like Klinefelter's and Turner's syndromes, inheritance patterns, cell division, and specific genetic disorders like Cri-du-chat syndrome, osteogenesis imperfecta, and progeria. Each question is followed by multiple choice answers and the correct response highlighted.
Population growth
This document discusses factors that cause population sizes to change, including births, deaths, immigration and emigration. It also examines different reproductive strategies in species and how population growth can resemble a J-curve or S-curve over time. Environmental pressures and limited resources can cause populations to stabilize or even crash if they overshoot the carrying capacity of the ecosystem.
Biosphere and biomes
This document summarizes the major levels of biological organization (biosphere, ecosystems, communities, populations, organisms) and describes the key characteristics of major biomes, including tundra, taiga, temperate deciduous forest, temperate grasslands, desert, savanna, and tropical rainforest. It provides temperature, precipitation, dominant species, and distinguishing features of each biome.

Ogt review science
1. Newton's laws of motion describe how forces cause objects to accelerate or remain at rest. Kinetic energy is the energy of motion while potential energy is stored energy due to position or structure.
2. The law of conservation of energy states that energy cannot be created or destroyed, only changed from one form to another, such as chemical to electrical. Heat can be transferred through conduction, convection, or radiation.
3. Chemical properties describe changes that produce new substances, while physical changes do not. Endothermic reactions absorb heat and exothermic reactions release heat. Phase changes alter a substance's state between solid, liquid, and gas.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
