TDikow Effect of taxon sampling in morphological phylogenetic studies ESA 2013Torsten Dikow
1. The study examined the effects of taxon sampling in morphological phylogenetic analyses using three fly families with different diversification rates: Apioceridae, Asilidae, and Mydidae.
2. For Apioceridae and Mydidae, excluding taxa resulted in trees with similar topology but poorer support, while including additional taxa generally corroborated relationships but sometimes altered the position of genera.
3. For Asilidae, inclusion of additional Bathypogon species did not alter the placement of the subgenus, suggesting dense sampling was not necessary to recover relationships in this group.
The document provides an overview of Afrotropical Mydidae, the most diverse family of flower flies worldwide. It notes that the Afrotropical region contains 44% of known Mydidae species diversity, including many endemic genera. The largest subfamily is Syllegomydinae, which contains 24 genera and nearly 200 species in the Afrotropical region. Several genera and species are described as particularly distinctive or in need of further taxonomic study. In summary, the Afrotropical region stands out for its high Mydidae diversity, with many species yet to be described or placed within genera.
The Andean Condor and California Condor are both critically endangered species. The Andean Condor is found in the Andes Mountains and adjacent Pacific coasts of South America, with the largest wingspan of any land bird at over 10 feet. The California Condor inhabits areas of Arizona, Utah, California and Baja California, and is North America's largest land bird, with a wingspan of nearly 10 feet. Both species are scavengers and face threats from habitat loss, pollution, and human activity that have drastically reduced their populations and ranges.

Domesticated birds have a long history originating from various regions around the world. Quail were first domesticated for their meat and egg production and originate from North America. Ducks were domesticated from mallards for their meat, eggs, and down. Turkeys were first domesticated in Mexico and the southwest United States by indigenous peoples and were later introduced to Europe. Pigeons have been domesticated for over 5000 years for their eggs and as carrier pigeons. Peafowl originate from India and Sri Lanka and are kept for their beauty and eggs. Pheasants originate from China and East Asia but have been introduced worldwide. Waterfowl, geese, and swans are raised for their meat and eggs.
Abstract:To fulfill our interest, we tried our best to observe the current status of squirrels in Bangladesh. In Bangladesh there are generally 8 species of squirrels which are different in size, color but same in food habit are found. From them, we observed that Pallas’s Squirrel (Callosciurus erythraeus), Irrawady Squirrel (Callosciurus pygerythrus), Three Stripped Palm Squirrel (Funambulus palmarum) and Five stripped Palm Squirrel (Funambulus pennantii) are widely distributed. A large number of variations were observed during winter and summer as we preferred these 2 seasons for our field study. All of them are frugivorous and sometimes feed on grass flowers too. Sometimes taking Insects as food fulfill the necessity of protein.
This study examines the phylogenetic relationships between Apioceridae and Mydidae fly families based on morphological characters of adult flies. The researchers analyzed 211 characters from over 160 fly species, representing all subfamilies and tribes of Mydidae and most Apiocera subgenera. The resulting phylogenetic trees strongly support the monophyly of Apioceridae and reveal southern hemisphere connections between some Apioceridae and Mydidae subfamilies, providing insight into the evolutionary history of these fly families.

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.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
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.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...Sérgio Sacani
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.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
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.
