Bioinformatics is the application of computational tools and techniques to analyze and interpret biological data. It involves the development of these tools and databases, as well as their application to better understand biological systems and functions at the molecular level through analysis of genetic sequences, protein structures, and more. The goal is to gain a global understanding of cellular functions by analyzing genetic data as dictated by the central dogma of biology, and relating sequence information to protein functions and cellular processes.

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.

Toxic effects of heavy metals : Lead and Arsenicsanjana502982
Heavy metals are naturally occuring metallic chemical elements that have relatively high density, and are toxic at even low concentrations. All toxic metals are termed as heavy metals irrespective of their atomic mass and density, eg. arsenic, lead, mercury, cadmium, thallium, chromium, etc.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skills
ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

All OS options are conceptually identical …
enabling control over files, folders, and programs
Linux command line! … the only option for compute
intense software
7. Bioinformatics Topics
Informatics Biology
Statistics
A basic understanding of Statistics is just as vital when
designing an experiment
When large datasets need to be interpreted, it demands a
working familiarity with a quality Statistical Package
Bioinformatics software commonly employs statistics to
select the most probable answer from a set of many possible
answers to a given question
8. Bioinformatics Topics
Informatics Biology
Data Generation
Experimental Data types include:
Sequences - Typically Next-Generation DNA Sequencing (NGS)
3D Protein Structures - X-ray crystallography or Nuclear
magnetic resonance spectroscopy (NMR)
Gene Expression Data - Microarrays
9. Bioinformatics Topics
Informatics Biology
Data Analysis
The Alignment of Pairs of Homologous DNA/Protein sequences
Fundamental to most forms of DNA/Protein Sequence analysis
Searching for Homologous Sequences in a Sequence Database
10. Database searching is the most common Bioinformatics
process by far
Database searching is pairwise comparison repeated many times
A list of matches, ordered by the improbability of occurring just by
chance is generated
12. Information can now be stored in Databases that allow
users easy and unrestricted access
Primary DNA Sequence Databases
Original submission by experimentalists content controlled by the
submitter
EMBL, NCBI-GenBank, DDBJ
Primary Protein Sequence Databases
PIR, Swissprot, TrEMBL
Genome Databases store entire genome sequence(s) AND their
interpretation
13. Protein Structure Databases
PDB, PDBj, CATH, SCOP
Gene Ontology Database
The Gene Ontology (GO) database provides a hierarchy of formally agreed terms
to describe gene products accurately and unambiguously
Searching with these terms radically improves the efficacy of
annotation searching
A simplistic ordering for the Bioinformatics Topics
14. Goal
- Ultimate goal - Better understand functions of cell at
the molecular level
- Bioinformatics research (raw seqs and structures)
can generate new insights and provide a “global”
perspective of the cell
- Cell functions can be better understood by analyzing
sequence data as flow of genetic information is
dictated by the “central dogma” of biology
- Cellular functions are performed by proteins whose
capabilities are determined by their sequences
- Therefore, solving functional problems using
sequence and sometimes structural approaches has
proved to be a fruitful endeavor
15. Scope
- Bioinformatics consists of two subfields
i) Development of computational tools and databases
ii) Application of these tools and databases in generating
biological knowledge to better understand living systems
- Tool development includes: writing software for sequence,
structural, and functional analysis, construction and curating of
biological databases
- Sequence analysis include sequence alignment, sequence
database searching, motif and pattern discovery, gene and
promoter finding, reconstruction of evolutionary relationships,
and genome assembly and comparison
- The three aspects of bioinformatics analysis are not isolated
but often interact to produce integrated results

17. Why is bioinformatics needed?
• Small- and large-scale biological analyses
• New laboratory technologies
• Move away from single gene to whole genome
• Genome sequencing
• Collection and storage of biological information
• Manipulation of biological information
• Computers have capability for both, and cheap
18. Problems and Challenges
Know the sequence of every possible
transcript but not understand the functions of
these transcripts and their corresponding
proteins!
How to make sense of all of the gene and
protein data in order to assign functions to
these genes and proteins and to understand
biological processes at the molecular level?
20. Challenges
Databases and data resources
Because we need to store and retrieve lots
of data
Search and analysis tools
Because we need to infer
function by comparison
Interfaces and visualisation tools
Because we need to look at
lots of data

22. What is the function of these structures?
What is the function of this sequence?
What is the function of this motif?
– the fold provides a scaffold, which can be decorated
in different ways by different sequences to confer
different functions
– knowing the fold & function allows us to rationalise
how the structure effects its function at the molecular
level
Goals of Functional Genomics
23. Tools currently available for genomics and
functional genomics studies
Standard molecular biology and protein analysis
techniques, i.e. hybridization, 2D gel
electrophoresis, SAGE, etc.
Advance technologies, i.e. microarray, GeneChips,
proteomics, etc.
Bioinformatics: gene annotation, gene and genome
analysis, data mining, etc.
24. Molecular Biology
• Central Dogma of Molecular Biology:
– molecules and processes.
• Molecular biology studies:
–structure of macromolecules (DNA, RNA and protein)
