Headache
The document provides an overview of various headache types, including their causes, characteristics, treatments and related conditions. It discusses primary headache disorders like migraines and tension headaches, as well as secondary headaches that can indicate underlying issues. Evaluation of patient history is important for diagnosis. Treatment involves managing acute episodes and preventing recurrent headaches through lifestyle changes and medications.
Headaches
Headaches are one of the most common medical complaints. They can be classified as primary or secondary, with primary headaches like migraines occurring independently and secondary headaches resulting from another underlying condition. Migraines specifically involve recurrent attacks of moderate to severe throbbing head pain and other symptoms like sensitivity to light and sound. They can be further divided into migraines with aura, which include neurological symptoms before the headache, and migraines without aura. Potential triggers of migraines include certain foods, environmental factors, and behaviors.
Migrane
Migraine is a common type of headache disorder characterized by recurrent headaches that can cause severe throbbing pain, nausea, vomiting, and sensitivity to light and sound. It is believed to involve changes in brain activity and inflammation of the blood vessels around the brain. Migraines can be further classified based on whether an "aura" occurs before the headache, as well as other associated neurological symptoms. Common triggers include hormonal changes, stress, foods, and environmental factors. Treatment involves managing acute attacks with over-the-counter or prescription medications as well as lifestyle changes and preventive medications to reduce frequency and severity of migraines.

- Trigeminal neuralgia is characterized by sudden, severe facial pain that occurs in the areas of the face served by the trigeminal nerve. The pain is often triggered by light touch or other minor stimuli. Examination will reveal no sensory deficits. Treatment options include pharmacotherapy, microvascular decompression, or trigeminal ganglion block/radiofrequency ablation.
- Cluster headache is a severe headache occurring as multiple attacks and characterized by excruciating unilateral orbital, supraorbital, or temporal pain lasting 15-180 minutes if untreated. Attacks are associated with ipsilateral cranial autonomic features and a sense of restlessness. Treatment involves acute abortive therapy with oxygen or triptans and prevent

- Headaches are a common neurological problem and migraine is the most frequent diagnosis in patients presenting with headache.
- Migraines affect 12-15% of the population and are characterized by distinct phases including prodrome, aura, headache, and postdrome. Common triggers include stress, hormones, sleep disturbances, and foods.
- Tension-type headaches are also very common and present as mild to moderate bilateral headaches without other symptoms. Treatment involves analgesics and behavioral therapies.
- Other primary headaches like cluster headaches and trigeminal autonomic cephalalgias present with short attacks of severe pain and autonomic symptoms. Emergency evaluation is needed for headaches with red flag symptoms.
Clinical Approach to Migraine ward case.pptx
Migraine is a type of headache characterized by recurrent moderate to severe throbbing pain on one side of the head lasting 4-72 hours. It is caused by activation of nerve fibers in brain blood vessels, and common symptoms include light/sound sensitivity, nausea, and vomiting. Risk factors include female sex, family history, depression/anxiety, and certain triggers like hormonal changes, stress, foods, and sleep changes. There are several types of migraine including those with and without aura, as well as menstrual, silent, vestibular, and abdominal migraines. Diagnosis involves history and tests to rule out other causes, while treatment depends on frequency and includes lifestyle changes, medications, and in rare cases surgery.
Pediatric headache by dr. milind bapat
Headaches are common in children, affecting 39% by age 6 and 75% by age 15. Migraines, the most common type of primary headache in children, can cause school absences and impair academic performance. Evaluation of childhood headaches should consider secondary causes from infections, injuries, or intracranial pathology. For primary headaches like migraines, treatment involves acute abortive medications and lifestyle changes to prevent triggers as well as prophylactic medications if headaches are frequent or severe.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
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 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.

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.

Plant breeding for disease resistance is a strategy to reduce crop losses caused by disease. Plants have an innate immune system that allows them to recognize pathogens and provide resistance. However, breeding for long-lasting resistance often involves combining multiple resistance genes
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.

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.
