The barrow ruptured aneurysm trial
The Barrow Ruptured Aneurysm Trial (BRAT) aimed to include all eligible patients with ruptured brain aneurysms to compare microsurgical clipping versus endovascular coiling. At 3-year follow-up, 35.8% of patients assigned to clipping and 30% assigned to coiling had poor outcomes, though this difference was no longer significant. Patients who crossed over from coiling to clipping had worse outcomes than those who remained in the coiled group. For posterior circulation aneurysms, outcomes were significantly better with coiling than clipping. While coiling reduces retreatment needs, clipping provides better aneurysm occlusion and protection from rebleeding long-term. Both treatments remain important options.

MRI Tractography IMAGING
Tractography uses diffusion MRI to visually represent nerve tracts in the brain through 3D modeling. It can reveal both long tracts connecting different brain regions and more complex short circuits within the brain. However, nerve tracts are not directly visible through standard imaging techniques. Diffusion MRI measures the directionality of water diffusion within tissues to infer the orientation of fiber tracts. Software then maps the diffusion data to generate color-coded 3D representations of tracts called tractograms. Tractography provides insights into the structure and integrity of white matter pathways in the living brain.

It discusses the three layers of the meninges (dura mater, arachnoid mater, pia mater), the arteries that supply the brain including the internal carotid and vertebral arteries, and key structures like the cingulate gyrus and central sulcus. Diagrams are included from the Digital Anatomist Project to illustrate these structures.
visual pathway.pptx
The visual pathway begins with light entering the retina and transmitting signals along the optic nerve. The two optic nerves meet at the optic chiasm before projecting to the lateral geniculate nucleus. Signals then travel along the optic radiations to the primary visual cortex in the occipital lobe. The visual cortex integrates this information and transmits it to additional visual processing areas for functions like object recognition and motion detection. Disruptions to the visual pathway can result in visual field defects depending on the location of injury or disease.
Neuroangio Internal carotid artery and its endovascular aspect
The document discusses the anatomy and variations of the internal carotid artery (ICA) and its branches. It describes the segments of the ICA including the cervical, petrous, cavernous, ophthalmic, hypophyseal, paraophthalmic, and communicating segments. It discusses variations such as persistent trigeminal artery and aberrant carotid arteries. It also summarizes aneurysms, loops, and other pathologies that can involve the different segments. Key branches including the meningohypophyseal trunk, inferolateral trunk, anterior choroidal artery, and posterior communicating artery are described. The document provides a comprehensive overview of the neuroangio of the ICA and its endovascular aspects.
State of the Art EP Lab
This document summarizes the state of the art technologies and techniques used in electrophysiology (EP) labs for cardiac ablation procedures. It discusses the history and evolution of ablation sources from radiofrequency to cryoablation and laser technologies. It also describes mapping systems, remote robotic navigation, ongoing clinical trials evaluating new approaches, and considerations for improving safety such as assessing anatomy and avoiding injury to nearby structures. Finally, it explores emerging areas of research like voltage mapping and the potential for substrate-based ablation to better treat atrial fibrillation.

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 cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

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.

Title: Gravitational wave detection with orbital motion of Moon and artificial
Abstract:
In this talk I will describe some recent ideas to find gravitational waves from supermassive black holes or of primordial origin by studying their secular effect on the orbital motion of the Moon or satellites that are laser ranged.Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

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.
