Electronics
1) Electrostatic charges involve the attraction and repulsion of objects based on whether they have equal or opposite charges. Charges are used in photocopiers, dust precipitators, and defibrillators.
2) Electricity involves the flow of electrons through conductors. The resistance of materials can change based on factors like temperature. Common circuit components include resistors, diodes, and capacitors.
3) Digital and analog signals are used to transmit information. Digital signals use 1s and 0s while analog signals have continuously varying values. Multiplexing and sampling allow more data to be transmitted.
Gene Extrapolation Models for Toxicogenomic Data
1) The document describes using gene expression data from landmark genes to build predictive models for extrapolating the expression of regular genes not in the landmark set.
2) Three different model types are evaluated: linear regression, elastic net, and neural networks. Elastic net is shown to outperform linear regression in terms of signal-to-noise ratio for the extrapolated expressions.
3) The performance of the different extrapolation models is assessed on their ability to predict carcinogenicity classifiers, and the correlation between expressions from different microarray platforms is examined.
Atom Presentation With Narration
This document provides an overview of atoms and atomic structure through a self-guided computer activity. It discusses the atomic-molecular theory of matter and how scientists have gathered indirect evidence to develop models of atoms. It describes the subatomic particles that make up atoms, including protons, neutrons, and electrons. Atoms are electrically neutral due to having equal numbers of protons and electrons. The activity guides students to learn about atomic structure by visiting websites and completing a study guide.
Atomic Structure Pure Edited
The document discusses atomic structure and subatomic particles. It explains that atoms are made up of a nucleus containing protons and neutrons, surrounded by electrons. The nucleus is positively charged while electrons are negatively charged. Atoms are electrically neutral overall since the positive and negative charges balance out. Isotopes are atoms of the same element that differ in the number of neutrons. Valence electrons determine an element's chemical properties and atoms can gain or lose electrons to achieve a full outer shell, becoming ions in the process.
Bohr 2
The document summarizes Niels Bohr's model of the atom from 1913. Bohr proposed that electrons orbit the nucleus in discrete, quantized energy levels. Electrons can jump between these energy levels, absorbing or emitting photons of light. The energy of the photons depends on the energy difference between the initial and final orbit. Bohr's model could only explain the hydrogen atom and failed to account for effects like the Zeeman and Stark effects seen in other atoms. Later developments in quantum mechanics disproved Bohr's idea of electrons having definite orbits.
Chapter 2 the structure of the atom
The document discusses the structure of atoms and isotopes. It begins by defining matter and the particle theory of matter. It then explains that atoms are made up of protons, neutrons and electrons. The atomic structure of various elements is discussed through their electron configurations. Isotopes are then introduced as atoms of the same element that have the same number of protons but different numbers of neutrons. Examples of isotopes including hydrogen and oxygen isotopes are provided.
Acceleration
Acceleration is the rate of change of velocity over time. It is measured in meters per second squared (m/s2) and describes how quickly an object's velocity changes. Acceleration is a vector quantity, which means it has both magnitude and direction associated with it.

Naturaldisasters
Natural disasters are major changes in the environment that can cause damage through volcanic eruptions, earthquakes, cyclones, thunderstorms, floods, droughts, and wildfires. Volcanic eruptions occur when gas and lava erupt from openings in the earth's crust due to pressure from deep inside. Earthquakes are violent shaking of the ground caused by movement of tectonic plates. Cyclones are fierce, spinning storms that can uproot trees, destroy buildings, and overturn cars. Droughts are long periods without rain, and fires can burn out of control in forest and bush areas.

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.

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.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

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.

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
