This study investigated habitat selection in the burrowing brittlestar Ophiophragmus filograneus by examining preferences for grain size, vegetation, and structure. Experiments found the brittlestar significantly preferred very fine grain sand and habitats with the sea grass Halodule wrightii. The presence of physical structure, like sea grass, was an important factor in habitat selection. The study demonstrates grain size and structural habitat components like sea grass influence the patchy distribution of this brittlestar species.

Presentation on morphology of rice plantAbdul Salim
The document describes the growth stages of rice plants from seed germination through flowering and grain development. It explains that when a rice seed germinates, the coleorhiza first emerges from the soil followed by the radicle root. Seedlings develop leaves and tillers, with roots and culms. The culm nodes bear leaves, and the top leaf is the flag leaf. Panicles form on the upper culm and bear spikelets with florets containing pistils, stamens and lodicules. Fertilization results in rice grains enveloped in hulls that protect the embryo and endosperm.

This document provides information about bony fishes. It begins by introducing the phylum Chordata and class Actinopterygii, which contains over 25,000 species of modern bony fish. It then discusses some key characteristics of bony fishes, including the presence of a swim bladder, bones, and fin rays. The document also describes coelacanths as a "primitive" fish that was thought to be extinct but has been found alive. The majority of the document focuses on ray-finned fishes, including their diversity, body shapes adapted to different habitats, and systems like respiration, circulation, nerves, senses, reproduction, and coloration.
This schedule outlines the week-by-week plan for a biology class focusing on arthropods, echinoderms, and fish. In the first week, students will take notes on arthropods and echinoderms, and participate in labs examining preserved specimens of these phyla. The second week involves dissecting starfish, analyzing lab results, and taking article-based and identification tests on echinoderms and arthropods. Later weeks shift to topics on fish, including their adaptations, building a model fish, quizzes, and a field trip to SeaWorld to observe aquatic life.
Echinoderms are marine invertebrates with spiny skin and five-part radial symmetry. They have a water-vascular system and tube feet used for movement. There are five classes of echinoderms: sea stars, brittle stars, sea urchins, sea cucumbers, and sea lilies. Sea stars have tube feet and a water vascular system that allows them to move and catch prey as carnivores. Sea urchins also have tube feet and move by grazing on algae and plants as herbivores. Sea cucumbers use their tube feet to move and take nutrients from sand with oral tentacles.
Here are a few methods a scientist could use to determine the population density of barnacle species on a dock post:
1. Count the number of individual barnacles within a defined area on the post (e.g. within a 1 square foot quadrat) and extrapolate the total number per post based on the surface area. This direct count method provides an estimate of density.
2. Weigh a sample of barnacles scraped from a defined area. Compare the wet or dry mass to samples of known densities to estimate individuals per unit area.
3. Take photographic images of sample areas and use image analysis software to automatically count and identify barnacles based on size, shape, color. This provides a repeatable quantitative measure
The document summarizes the three major classes of mollusks - Gastropoda (snails and slugs), Bivalvia (clams and oysters), and Cephalopoda (octopuses, squid, and cuttlefish). It describes their general body plans, anatomy, locomotion, digestion, respiration, reproduction, ecological roles, and adaptations for predation. Mollusks exhibit a diversity of forms and play important roles in both marine and terrestrial ecosystems.
Marine science national invasive species week!!!!kleinkea
National Invasive Species Week is being celebrated, with students assigned to research and create a warning flyer about an invasive species in Florida. The Burmese python is highlighted as an example, with details provided that it is native to Southeast Asia but has been released in Florida, where it has no natural predators and is attacking wildlife in the Everglades. Students are warned to keep Burmese pythons in Asia and not buy exotic pets. The assignment is due by March 8th.
This document summarizes key characteristics of sponges, cnidarians, and comb jellies. Sponges are sessile, multicellular organisms that filter feed and lack tissues. Cnidarians are radially symmetric and have stinging cells, with forms including polyps, jellyfish, corals, and sea anemones. Comb jellies differ in having eight rows of comb plates with cilia for locomotion and lack stinging cells.
This document discusses the four main phyla of multicellular primary producers: seaweeds (Phaeophyta, Rhodophyta, Chlorophyta), seagrasses, salt marsh plants, and mangroves. It describes their key structures, reproduction methods, ecological roles, and representative species found in Florida. The main environmental factors that influence seaweeds are light, temperature, tidal exposure, salinity, and nutrient availability.
This study guide covers the key structures, reproductive systems, digestive systems, levels of organization, and ecological roles of diatoms, dinoflagellates, foraminiferans, Euglena, and Volvox. It includes diagrams of representative organisms and definitions of important terms. Short answer questions ask the student to compare and contrast diatoms, dinoflagellates, and forams, and describe the food capture methods of foraminiferans.

This document summarizes key marine microbes found in plankton. It discusses diatoms, dinoflagellates, and forams in detail, including their structure, reproduction, digestion/energy processes, and ecological roles. Diatoms are the most common and distinctive plankton, contributing greatly to primary productivity. Dinoflagellates can cause harmful algae blooms and red tides. Forams consume other microbes and turn over nutrients. The document also briefly outlines euglena and volvox characteristics.
This document summarizes key marine microbes found in plankton. It discusses diatoms, dinoflagellates, forams, euglena, and volvox. Diatoms are the most common phytoplankton and have a glassy cell wall and symmetrical shape. Dinoflagellates can cause red tides and some are in a mutualism with corals. Forams have a shell and pseudopod and are an important part of the marine food web. Euglena can photosynthesize or absorb nutrients and reproduce by binary fission. Volvox forms multicellular colonies through asexual reproduction and provides a model for cell regeneration studies.
This document provides questions to guide the reader in understanding key concepts about plankton from a scientific text. It includes questions about why plankton are called "drifters", how they are able to live near the surface of oceans, and adaptations like buoyancy. Questions also address the thermocline, how water density affects mixing, and how this benefits plankton. Further questions explore plankton's role in food chains, characteristics of "jello-plankton", and the process of vertical diurnal migration. The final question looks at what time of year is optimal for plankton growth and why.
Ecology is the study of interactions between organisms and their environment. It examines these relationships across different levels of biological organization, from cells to the biosphere. An organism's environment, or abiotic factors like temperature and salinity, as well as biotic interactions with predators, prey and parasites, define its habitat and ecological niche. Competition occurs when organisms require the same limited resources, preventing two groups from occupying the same niche. Predator-prey relationships and keystone species also shape ecosystem structure. Symbiosis describes close biological interactions, which can be mutualistic, commensal, or parasitic. Scientists sample populations using methods like transect lines and quadrats to make inferences about ecosystem health.
This document provides directions for a research paper assignment. Students must choose one of seven topics covered in class and write a 6-page paper in 12pt font and double spaced with a cover page and works cited page. The paper must include at least 10 sources, with 5 being primary sources. The final draft is due on December 14th by 2:15pm as a Word 2007 attachment via email. Plagiarized papers will receive a grade of 0.
This document is a syllabus for a marine science course taught by Ms. Kleinke. The syllabus outlines the course objectives, description, materials required, grading breakdown, behavior expectations, homework policy, tests/quizzes, and learning recovery options. The objective is for students to gain a deeper understanding of the unique and interconnected properties and organisms of the ocean. Labs and hands-on activities are emphasized. Students are expected to be prepared, respectful, engaged, and work hard. Consequences are outlined for violations and late work policies are described.
The study explored the effects of low salinity water on ion transporter expression and distribution in the gill of the longhorn sculpin (Myoxocephalus octodecimspinosus). Sculpins were exposed to 10% or 20% seawater for 24 or 72 hours. Exposure to 10% seawater resulted in 20-25% lower plasma ion levels but did not affect transporter localization or expression. Sculpins maintained ion levels in 20% seawater and showed no physiological effects. The results suggest sculpins can tolerate brackish water for days but not long term due to an inability to regulate transporters at low salinities.
The document discusses the central role played by the Mt. Desert Island Biological Laboratory (MDIBL) in advancing the study of fish osmoregulation over the past 80 years. Some of the key discoveries made by scientists at MDIBL include demonstrating that marine fish ingest seawater and absorb water and ions from their intestines, determining that aglomerular fish kidneys can function excretory like glomerular kidneys, and elucidating the role of gills in salt secretion. The MDIBL has hosted many influential researchers in fish physiology and helped establish the basic mechanisms of osmoregulation in fish.
Lesson 2 osmosis and diffusion in the marine environmentkleinkea
The document summarizes how different fish species regulate water concentration in their cells when in environments with different salt concentrations. Some fish, like those in marine environments, actively transport ions to maintain higher internal salt concentrations than the surrounding water to prevent their cells from bursting. Other fish, called osmoconformers, allow their internal salt concentrations to rise and fall passively with the environment. Maintaining precise internal regulation requires energy, so some species like cod produce high concentrations of urea to control balances. The document emphasizes the importance of these mechanisms for fish to adapt to varying salinity conditions in their habitats.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

Main news related to the CCS TSI 2023 (2023/1695)Jakub Marek
An English 🇬🇧 translation of a presentation to the speech I gave about the main changes brought by CCS TSI 2023 at the biggest Czech conference on Communications and signalling systems on Railways, which was held in Clarion Hotel Olomouc from 7th to 9th November 2023 (konferenceszt.cz). Attended by around 500 participants and 200 on-line followers.

How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.
"Frontline Battles with DDoS: Best practices and Lessons Learned", Igor IvaniukFwdays
At this talk we will discuss DDoS protection tools and best practices, discuss network architectures and what AWS has to offer. Also, we will look into one of the largest DDoS attacks on Ukrainian infrastructure that happened in February 2022. We'll see, what techniques helped to keep the web resources available for Ukrainians and how AWS improved DDoS protection for all customers based on Ukraine experience
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
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.

From Natural Language to Structured Solr Queries using LLMsSease
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
