Voltage is a measure of electrical potential energy per unit charge. It is defined as the change in electrical energy of a charged particle moving between two points in space. Voltage is a property of all points in space, not just batteries, and is measured in units of joules per coulomb (volts). The voltage difference between two points determines the electrical force exerted on a charged particle and the power dissipated during the flow of electricity according to defined equations.

Pharmaceutical science
The electrical double layer theory deals with the distribution of ions that occurs at the interface between a charged solid surface (such as a colloid) in contact with an aqueous electrolyte solution. The theory proposes that ions of the opposite charge are attracted to the solid surface (known as the potential determining ions), forming a tightly bound layer, giving the surface a net positive or negative charge. Nearby, counter ions of the opposite charge form a diffuse layer in the solution. The difference in electric potential between the charged surface and the neutral point in the diffuse layer is known as the Nernst potential. The electrical double layer consists of a fixed Stern layer near the surface and a diffuse layer extending into the solution.

Opposite charges attract each other, while similar charges repel. The standard unit of electric charge is the coulomb. All matter contains positively charged protons and negatively charged electrons. Substances can be conductors or insulators depending on how easily electric charges can flow through them.

Conductors allow electric charges to flow easily, while insulators do not. Coulomb's law states that the electrostatic force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.

Solution
CHARGE:
Electric charge is the physical property of matter that causes it to experience a force when placed
in an electromagnetic field. There are two types of electric charges: positive and negative. Like
charges repel and unlike attract. An object (one not made of antimatter) is negatively charged if
it has an excess of electrons, and is otherwise positively charged or uncharged. The SI derived
unit of electric charge is the coulomb (C). In electrical engineering, it is also common to use the
ampere-hour (Ah), and, in chemistry, it is common to use the elementary charge (e) as a unit.
The symbol Qoften denotes charge. Early knowledge of how charged substances interact is now
called classical electrodynamics, and is still accurate for problems that don\'t require
consideration of quantum effects.
CURRENT:
An electric current is a flow of electric charge. In electric circuits this charge is often carried by
moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and
electrons such as in a plasma.
The SI unit for measuring an electric current is the ampere, which is the flow of electric charge
across a surface at the rate of one coulomb per second. Electric current is measured using a
device called an ammeter.
Electric currents cause Joule heating, which creates light in incandescent light bulbs. They also
create magnetic fields, which are used in motors, inductors and generators.
The particles that carry the charge in an electric current are called charge carriers. In metals, one
or more electrons from each atom are loosely bound to the atom, and can move freely about
within the metal. These conduction electrons are the charge carriers in metal conductors.
VOLTAGE
Voltage, electric potential difference, electric pressure or electric tension (formally denoted V or
U, but more often simply as V or U, for instance in the context of Ohm\'s or Kirchhoff\'s laws) is
the difference in electric potential energy between two points per unit electric charge. The
voltage between two points is equal to the work done per unit of charge against a static electric
field to move the test charge between two points and is measured in units of volts(a joule per
coulomb).
Voltage can be caused by static electric fields, by electric current through a magnetic field, by
time-varying magnetic fields, or some combination of these three. A voltmeter can be used to
measure the voltage (or potential difference) between two points in a system; often a common
reference potential such as the ground of the system is used as one of the points. A voltage may
represent either a source of energy (electromotive force), or lost, used, or stored energy (potential
drop).
POWER:
Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI
unit of power is the watt, one joule per second. Electric power is usua.
Physics ohm’s law
1. The document describes how current flows through a circuit using an analogy of charges moving up an escalator (battery) and through a paddle wheel (resistor).
2. Key components of a simple circuit are identified as a voltage source, conductive path, and resistor. Resistance is explained as how much an object resists electron flow.
3. Factors that determine resistance are described as the type of material, its thickness and length, and temperature. Conductors have low resistance while insulators have high resistance.

Okay, let's break this down step-by-step:
1) The electric field E is uniform, so E has a constant magnitude and direction.
2) The path icf consists of two segments: ic and cf.
3) For ic, the displacement is at a 90° angle to E so no work is done along that segment.
4) For cf, the displacement forms a 45° angle with E.
So the key is to integrate E×ds along just the cf segment.

PPT GROUP 2 ESM MATTER AND ENERGY.pptx
The document discusses different forms of energy and energy transformations. It contains the following key points:
1. Energy can take different forms including chemical, thermal, radiant, and electrical. Energy is constantly transforming between forms in the world around us.
2. The law of conservation of energy states that energy cannot be destroyed but can be transformed from one form to another for energy purposes.
3. As a mountain biker pedals up a hill, their chemical energy is transformed to kinetic energy which then transforms to potential energy as they climb the hill.

ESR spectroscopy in liquid food and beverages.pptx
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.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

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 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.

- 5. Lightbulbs are rated in units of watts. Units of joules per coulomb are abbreviated as volts, 1 V=1 J/C, named after the Italian physicist Alessandro Volta. Everyone knows that batteries are rated in units of volts, but the voltage concept is more general than that; it turns out that voltage is a property of every point in space. The Volt Unit
- 6. To do work on a charged particle, the battery apparently must be exerting forces on it. The only thing that can exert an electrical force on a charged particle is another charged particle. It’s as though the haybales were pushing and pulling each other into the hayloft! This is potentially a horribly complicated situation. There are two ways in which we can simplify things: 1. The situation is unchanging 2. Force depends only on position
- 7. The difference in voltage between two points in space is defined as: where ∆Uelec is the change in the electrical energy of a particle with charge q as it moves from the initial point to the final point. The amount of power dissipated (i.e., rate at which energy is transformed by the flow of electricity) is then given by the equation:
- 8. Voltage is electrical potential energy per unit charge, so the voltage difference between the two plates of the capacitor is related to the amount by which its energy would increase if we increased the absolute values of the charges on the plates from q to q + ∆q:
