This paper explores phenomenologically the way in which Godly Play, as an approach to religious education with young children devised by Jerome Berryman, provides an experience of truth as disclosure and openness – as a constant interplay between showing and hiding – though an exploration of Heidegger's (and to a lesser extent, Gadamer's) understanding of truth as aletheia. It applies this notion to one life expression in the Godly Play room in which a parable is presented to show how truth is revealed through the telling of the parable. Some implications for practice are posited as a result of this phenomenological reflection. [ABSTRACT FROM AUTHOR]

We searched late Miocene sedimentary rocks in an attempt to recover fossil micrometeorites derived from the Veritas asteroid family. This study was motivated by the previous identification of a pronounced 3He peak (4-5x above background) within marine sediments with ages between ∼8.5–6.9 Ma ago (Montanari et al., 2017. GSA Bulletin, 129:1357–1376). We processed 118.9 kg of sediment from the Monte dei Corvi beach section (Italy), the global type-section for the Tortonian epoch (11.6–7.2 Ma). Samples were collected both before and within the 3He peak. Although a small number of iron-rich (I-type) fossil micrometeorites were recovered from each horizon studied (N total = 20), there is no clear difference between the pre- and intra- 3He peak samples. All micrometeorites are compositionally similar, and three out of five horizons yielded similar abundances and particle sizes. Micrometeorites extracted from sediments at the base of the 3He peak were exclusively small (ø <75 µm), while micrometeorites extracted from sediments near the highest 3He values were relatively large (ø <270 µm). The recovered fossil micrometeorites are interpreted as samples of the background dust flux derived from metal-bearing chondritic asteroids. The presence of a 3He signature combined with the absence of fossil micrometeorites or extraterrestrial spinels (Boschi et al., 2019, Spec. Pap. Geol. Soc. Am. 542:383–391) unambiguously related to the Veritas event suggests that the Veritas family is composed of highly friable materials that rarely survive on the sea floor to become preserved in the geological record. Our data supports the existing hypothesis that the Veritas asteroid family is an aqueously altered carbonaceous chondrite parent body, one that contains minimal native metal grains or refractory Cr-spinels. The low yield of fossil micrometeorites at Monte dei Corvi is attributed to loss of particles by dissolution whilst they resided on the sea floor but also due to high sedimentation rates leading to dilution of the extraterrestrial dust flux at this site. As with other fossil micrometeorite collections (e.g. Cretaceous chalk [Suttle and Genge, EPSL, 476:132–142]) the I-type spherules have been altered since deposition. In most particles, both magnetite and wüstite remain intact but have been affected by solid state geochemical exchange, characterised by partial leaching of Ni, Co and Cr and implantation of Mn, Mg, Si and Al. In some particles Mn concentrations reach up to 16.6 wt%. Conversely, in some micrometeorites wüstite has been partially dissolved, or even replaced by calcite or ankerite. Finally, we observe evidence for wüstite recrystallisation, forming a second generation of magnetite. This process is suggested to occur by oxidation during residence on the seafloor and has implications for the use of fossil I-type micrometeorites as a potential proxy for probing Earth's upper atmospheric composition (oxidative capacity) in the geological past. However, solutions to the limitations of post-depositional recrystallisation are suggested. Fossil I-type spherules remain a potential tool for palaeo-climatic studies. [ABSTRACT FROM AUTHOR]

Previous detections of individual astrophysical sources of neutrinos are limited to the Sun and the supernova 1987A, whereas the origins of the diffuse flux of high-energy cosmic neutrinos remain unidentified. On 22 September 2017, we detected a high-energy neutrino, IceCube-170922A, with an energy of ~290 tera-electron volts. Its arrival direction was consistent with the location of a known γ-ray blazar, TXS 0506+056, observed to be in a flaring state. An extensive multiwavelength campaign followed, ranging from radio frequencies to γ-rays. These observations characterize the variability and energetics of the blazar and include the detection of TXS 0506+056 in very-high-energy γ-rays. This observation of a neutrino in spatial coincidence with a γ-ray-emitting blazar during an active phase suggests that blazars may be a source of high-energy neutrinos.

- Abstract
Die Herkunft galaktischer sehr hochenergetischer und ultrahochenergetischer kosmischer Strahlung bleibt rätselhaft, aber Studien weisen auf zahlreiche galaktische Quellen namens PeVatrons hin, die Teilchen auf Petaelektronenvolt-Energien beschleunigen können, darunter Pulsarwindnebel, Supernovareste und Mikroquasare. Die Untersuchung der Gammastrahlung bei Giga- und Teraelektronenvolt-Energien bietet entscheidende Einblicke in ihre Eigenschaften und erweitert unser Verständnis hochenergetischer astrophysikalischer Phänomene. Diese Arbeit analysiert Daten des VERITAS-Gammastrahlenobservatoriums, bestehend aus vier 12-Meter-Tscherenkow-Teleskopen in Arizona, um ein umfassendes Verständnis von zwei galaktischen Quellen zu liefern: MGRO J1908+06, ein potenzieller PeVatron-Kandidat, und SS 433, ein Mikroquasar. MGRO J1908+06 wurde bereits in verschiedenen Wellenlängen untersucht, wobei mehrere potenzielle Ursprünge der Strahlung identifiziert wurden. Diese Arbeit führt eine umfassende Neuuntersuchung seiner ausgedehnten Gammastrahlenemissionen durch, um präzisere Abschätzungen des Gammastrahlenflusses zu liefern und frühere Ergebnisse zu aktualisieren. Die Untersuchung deutet auf einen möglichen Ursprung der Gammastrahlung sowohl aus einem Relikt eines Pulsar-Windnebels als auch aus einem neuen Pulsar-Windnebel im Feld von MGRO J1908+06 hin. Erstmals wird in den VERITAS-Daten eine signifikante Gammastrahlenemission von SS 433 festgestellt. Es werden die Gammastrahlen der Jets bei größeren Abständen und ihre Morphologie untersucht, und TeV-Spektren werden generiert. Modelle zeigen einen leptonischen Ursprung dieser Emissionen, ohne dass eine signifikante Gammastrahlenemission in der Nähe des Schwarzen Lochs oder Anzeichen für Variabilität beobachtet werden. Ausblickend präsentiert die Arbeit Untersuchungen zur Optimierung der Eigenschaften des Cherenkov-Teleskop-Array Observatoriums, mit Fokus auf die Platzierung von Illuminatoren und Abschattungseffekte zwischen Teleskop, The origins of galactic very-high energy and ultra-high energy cosmic rays remain elusive. Recent studies propose the existence of PeVatrons, galactic sources capable of accelerating particles to Petaelectronvolt energies, such as pulsar wind nebulae, supernova remnants, and micro-quasars. Exploring gamma-ray emission at Giga- and Teraelectronvolt energies offers crucial insights into their properties, enriching our understanding of high-energy astrophysical phenomena. This thesis focuses on analysing data from the VERITAS gamma-ray observatory, comprising four 12-meter imaging atmospheric Cherenkov telescopes in Arizona. Employing 3D maximum-likelihood analysis methods, the study aims to provide a comprehensive understanding of two extended galactic sources: MGRO J1908+06, a potential PeVatron candidate, and SS 433, a microquasar. MGRO J1908+06, though unidentified, has been scrutinized across various wavelengths, with several potential counterparts identified previously. This thesis undertakes a re-analysis of its extended gamma-ray emission, leveraging updated analysis methods and recent VERITAS observations. The improved analysis method provides a more accurate estimate of the gamma-ray flux, revising prior VERITAS flux estimates and suggesting a scenario involving both relic and new pulsar wind nebulae. Regarding SS 433, significant gamma-ray emission is detected in VERITAS data for the first time. The morphological properties of the gamma-ray emission regions seen at larger distances along the jets are examined, and their TeV spectra are constructed. Modelling supports a leptonic origin of these emissions, with no significant gamma-ray emission observed near the black hole or any indication of variability. Looking ahead, the thesis presents investigations aimed at optimizing the characteristics of the Cherenkov Telescope Array Observatory, focusing on illuminator placement and mutual shadowing effects to enhance telescope positioning within the array.

- Abstract
This study examines the complex interplay between social and spatial structures among older adults, emphasizing the interest in considering the social composition of activity spaces and the spatial characteristics of social networks. There is a growing interest in the collection and analysis of both social and daily mobility spatial information to better understand people-place interactions and determinants of health. Yet, few analyses have explored how the social and spatial dimensions of people's lives relate. In this exploratory study, we analyze how social and spatial indicators collected with the VERITAS-Social questionnaire among 98 older adults in Montréal, Canada, relate, using confirmatory principal component analysis. The aim of the article is to provide empirical evidence on the reduction of dimensions of measures related to social networks, activity spaces, and combined socio-spatial structures., (Copyright © 2024.

Background: Plaque incision and grafting (PEG) is one of the mainstays in surgical therapy for severe penile curvature in Peyronie's disease (PD). Different kinds of grafts are available for covering albugineal defects during PEG, both allografts and xenografts. However, to date, none of these proved superior to others. Objectives: To compare two different types of xenograft, porcine dermal matrix and bovine pericardium matrix in PEG for PD. Materials and methods: From 2010 to 2019, 63 patients with PD underwent PEG, using porcine dermal (n = 25; Group 1) and bovine pericardium (n = 38; Group 2) grafts. Long‐term outcomes were evaluated through multi‐disciplinary questionnaires administration by phone interview. The following items were considered: correction of penile bending, quality of erection, intercourse ability, penile shortening, and sensitiveness. Overall satisfaction and impact of surgery on sexual activity and quality of life were also investigated. Results: Plaque median (IQR) size was 29 (22‐33) mm and was smaller in Group 1 (27.5 vs. 31 mm; P =.03). Complete follow‐up data were available for 53 patients (84%). Considering post‐operative outcomes, no differences were found when considering ED rates, penile shortening, sensitiveness, complications, and penile straightening (all P >.1). Patients in Group 2 were more likely to have palpable penile nodules at follow‐up (20.6 vs. 0%; P =.03). However, patient's post‐operative sexual life satisfaction was consistent between the two groups, with just 1 (5.3) and 8 (23.5) patients in Group 1 and 2 respectively referring a worsening in sexual life satisfaction (P = 0.2). At follow‐up, 84.9% of patients that would still undergo surgery for PD, with no statistical difference between the two groups (P =.4). Conclusions: Corporoplasty with PEG is an effective treatment for men with PD. Porcine dermal and bovine pericardium xenografts seem to have similar long‐term outcomes. [ABSTRACT FROM AUTHOR]

The aim of this study was to compare inflammatory response and synovial metaplasia in implant-based immediate breast reconstruction with a biological mesh (Veritas®) with that of a synthetic mesh (TIGR® Matrix Surgical Mesh). We hypothesize that the inflammatory response and formation of synovial metaplasia might be different and the rate of capsular contracture therefore different. The patients were recruited from the Gothenburg TIGR®/Veritas® Study (ClinicalTrials.Gov identifier NCT02985073). All referrals for bilateral immediate breast reconstruction were assessed for inclusions. During the operation, the patients were randomized to which sides the biological and the synthetic mesh were going to be applied. During the implant exchange biopsies were taken. Biopsies were taken from 30 breasts in 15 patients. There seem to be more myofibroblast and neovascularization in the biological meshes than in the synthetic and the collagen fibers seem to be aligned in an irregular pattern with both parallel and vertical fibers. In the synthetic meshes, there were more giant cells and foreign body reaction and the collagen fibers were loosely and well aligned, oriented parallel to the surface of the implant. Synovial metaplasia was seen in the majority of both the biological and the synthetic meshes. The histological patterns in early capsules from biological and synthetic meshes vary considerably. Nonetheless, it is unknown what role different cell types have in capsular formation in the long run and there was no difference in clinical capsular contracture at the clinical follow-up in this study.

- Abstract
Die Studie versucht, Husserls Modell einer nicht-wissenschaftlichen Lebenswelt für pädagogische Untersuchungen zum Verhältnis von Technik und Bildung in der verwissenschaftlichen Welt zu öffnen. Sie diskutiert Entwicklungsprobleme der Spätmoderne unter pluralen Fragestellungen und führt Ansätze und Traditionen zusammen, die unterschiedliche Wege zur Weiterentwicklung der modernen Bildungstheorie beschritten haben. Im Zentrum steht die Frage, wie moderne Technik einerseits als lebensweltliche Entfremdung des Menschen problematisiert und andererseits als Produkt menschlicher Freiheit und Weltgestaltung gewürdigt werden kann. In vier Kapiteln werden die methodischen Ansätze und Antworten vorgestellt, die der Philosoph und Pädagoge Eugen Fink (1905–1975), der Philosoph Martin Heidegger (1889–1976), der Philosoph und Erziehungswissenschaftler Theodor Litt (1880–1962) und der Soziologe Helmut Schelsky (1912–1984) auf die Frage nach dem Verhältnis von Bildung und Technik gegeben haben. Im Durchgang durch ihre Positionen wird ein Konzert erarbeitet, dessen Originalität darin liegt, Abstimmungsprobleme von Bildung, Technik und Lebenswelt aus postdualistischer, praxistheoretischer sowie posthumanistischer Perspektive zu thematisieren., The study attempts to open Husserl's model of a non-scientific lifeworld for pedagogical investigations of the relationship between technology and “Bildung” in the scientific world. It discusses developmental problems of late modernity under plural questions and brings together approaches and traditions that have taken different paths to the further development of modern “Bildungs”-theory. The central question is how modern technology can be problematized on the one hand as the alienation of human beings from the world of life and on the other hand be appreciated as a product of human freedom and the shaping of the world. Four chapters present the methodological approaches and answers that philosopher and educator Eugen Fink (1905–1975), philosopher Martin Heidegger (1889–1976), philosopher and educationalist Theodor Litt (1880–1962), and sociologist Helmut Schelsky (1912–1984) have given to the question of the relationship between education and technology. In the course of their positions, a concert will be developed whose originality lies in addressing the coordination problems of “Bildung” (education), “Technik” (technology) and “Lebenswelt” (lifeworld) from a post-dualist, praxis-theoretical as well as post-humanist perspective.

Die Studie versucht, Husserls Modell einer nicht-wissenschaftlichen Lebenswelt für pädagogische Untersuchungen zum Verhältnis von Technik und Bildung in der verwissenschaftlichen Welt zu öffnen. Sie diskutiert Entwicklungsprobleme der Spätmoderne unter pluralen Fragestellungen und führt Ansätze und Traditionen zusammen, die unterschiedliche Wege zur Weiterentwicklung der modernen Bildungstheorie beschritten haben. Im Zentrum steht die Frage, wie moderne Technik einerseits als lebensweltliche Entfremdung des Menschen problematisiert und andererseits als Produkt menschlicher Freiheit und Weltgestaltung gewürdigt werden kann. In vier Kapiteln werden die methodischen Ansätze und Antworten vorgestellt, die der Philosoph und Pädagoge Eugen Fink (1905–1975), der Philosoph Martin Heidegger (1889–1976), der Philosoph und Erziehungswissenschaftler Theodor Litt (1880–1962) und der Soziologe Helmut Schelsky (1912–1984) auf die Frage nach dem Verhältnis von Bildung und Technik gegeben haben. Im Durchgang durch ihre Positionen wird ein Konzert erarbeitet, dessen Originalität darin liegt, Abstimmungsprobleme von Bildung, Technik und Lebenswelt aus postdualistischer, praxistheoretischer sowie posthumanistischer Perspektive zu thematisieren., The study attempts to open Husserl's model of a non-scientific lifeworld for pedagogical investigations of the relationship between technology and “Bildung” in the scientific world. It discusses developmental problems of late modernity under plural questions and brings together approaches and traditions that have taken different paths to the further development of modern “Bildungs”-theory. The central question is how modern technology can be problematized on the one hand as the alienation of human beings from the world of life and on the other hand be appreciated as a product of human freedom and the shaping of the world. Four chapters present the methodological approaches and answers that philosopher and educator Eugen Fink (1905–1975), philosopher Martin Heidegger (1889–1976), philosopher and educationalist Theodor Litt (1880–1962), and sociologist Helmut Schelsky (1912–1984) have given to the question of the relationship between education and technology. In the course of their positions, a concert will be developed whose originality lies in addressing the coordination problems of “Bildung” (education), “Technik” (technology) and “Lebenswelt” (lifeworld) from a post-dualist, praxis-theoretical as well as post-humanist perspective.

The astrophysical journal / 1 950(2), 152 (2023). doi:10.3847/1538-4357/acd2d0, We report the detection of very high energy gamma-ray emission from the blazar S3 1227+25 (VER J1230+253) with the Very Energetic Radiation Imaging Telescope Array System (VERITAS). VERITAS observations of the source were triggered by the detection of a hard-spectrum GeV flare on 2015 May 15 with the Fermi-Large Area Telescope (LAT). A combined 5 hr VERITAS exposure on May 16 and 18 resulted in a strong 13σ detection with a differential photon spectral index, Γ = 3.8 ± 0.4, and a flux level at 9% of the Crab Nebula above 120 GeV. This also triggered target-of-opportunity observations with Swift, optical photometry, polarimetry, and radio measurements, also presented in this work, in addition to the VERITAS and Fermi-LAT data. A temporal analysis of the gamma-ray flux during this period finds evidence of a shortest variability timescale of τ$_{obs}$ = 6.2 ± 0.9 hr, indicating emission from compact regions within the jet, and the combined gamma-ray spectrum shows no strong evidence of a spectral cutoff. An investigation into correlations between the multiwavelength observations found evidence of optical and gamma-ray correlations, suggesting a single-zone model of emission. Finally, the multiwavelength spectral energy distribution is well described by a simple one-zone leptonic synchrotron self-Compton radiation model., Published by Institute of Physics Publ., London

- Abstract
Daily mobility, defined as the ability to move oneself within one's neighborhood and regions beyond, is an important construct, which affects people as they age. Having a feasible and valid measure of daily mobility is essential to understand how it affects older adults' everyday life. Given the limitations of existing measures, new tools may be needed. The purpose of the study is to assess the feasibility and practicality of using the map-based questionnaire system VERITAS and GPS devices to measure daily mobility in older adults living in a deprived neighborhood in Denmark. Older adults were recruited from two senior housing areas, completed an interview using VERITAS and wore a GPS for 7 days. Feasibility of both methods was assessed by looking at practicalities, recruitment and compliance, and ability to measure daily mobility. Thirty-four older adults completed the VERITAS questionnaire, of which 23 wore the GPS device. Remembering to wear and charge the GPS was difficult for 48% participants, whereas remembering street names and drawing routes in VERITAS was difficult for two. Both the GPS and VERITAS were able to measure 10 out of the 13 identified components of mobility; however, VERITAS seemed more qualified at measuring daily mobility for this target population. The feasibility of assessing mobility may vary by specific context and study population being investigated. Wearable technology like a GPS may not be acceptable to low socioeconomic older adults, whereas interview led self-reported measurements like VERITAS might be more suitable for a low socioeconomic elderly population.

The astrophysical journal / 1 945(2), 101 (2023). doi:10.3847/1538-4357/acbc7b, Dark matter is a key piece of the current cosmological scenario, with weakly interacting massive particles (WIMPs) a leading dark matter candidate. WIMPs have not been detected in their conventional parameter space (100 GeV ≲M $_{χ}$ ≲ 100 TeV), a mass range accessible with current Imaging Atmospheric Cherenkov Telescopes. As ultraheavy dark matter (UHDM; M $_{χ}$ ≳ 100 TeV) has been suggested as an underexplored alternative to the WIMP paradigm, we search for an indirect dark matter annihilation signal in a higher mass range (up to 30 PeV) with the VERITAS γ-ray observatory. With 216 hr of observations of four dwarf spheroidal galaxies, we perform an unbinned likelihood analysis. We find no evidence of a γ-ray signal from UHDM annihilation above the background fluctuation for any individual dwarf galaxy nor for a joint-fit analysis, and consequently constrain the velocity-weighted annihilation cross section of UHDM for dark matter particle masses between 1 TeV and 30 PeV. We additionally set constraints on the allowed radius of a composite UHDM particle., Published by Institute of Physics Publ., London

Superluminous supernovae (SLSNe) are a rare class of stellar explosions with luminosities ~10-100 times greater than ordinary core-collapse supernovae. One popular model to explain the enhanced optical output of hydrogen-poor (Type I) SLSNe invokes energy injection from a rapidly spinning magnetar. A prediction in this case is that high-energy gamma rays, generated in the wind nebula of the magnetar, could escape through the expanding supernova ejecta at late times (months or more after optical peak). This paper presents a search for gamma-ray emission in the broad energy band from 100 MeV to 30 TeV from two Type I SLSNe, SN2015bn, and SN2017egm, using observations from Fermi-LAT and VERITAS. Although no gamma-ray emission was detected from either source, the derived upper limits approach the putative magnetar's spin-down luminosity. Prospects are explored for detecting very-high-energy (VHE; 100 GeV - 100 TeV) emission from SLSNe-I with existing and planned facilities such as VERITAS and CTA.

Background: Veritas® collagen matrix is derived from bovine pericardium and is currently used in soft tissue and breast reconstruction. This study reports the experience of implant-based breast reconstruction using Veritas® collagen matrix in a specialist breast unit.Methods: This case series included all consecutive patients undergoing mastectomy and implant-based reconstruction using Veritas® over an 18-month period. Demographics, risk factors, operative parameters and postoperative outcomes were recorded prospectively.Results: Nineteen patients underwent a total of 30 breast reconstruction procedures over the study period. Of these, 57.9% (N = 11) had bilateral procedures. Breast cancer was the commonest indication. Forty percent (N = 12) had concomitant axillary surgery. Forty percent (N = 12) had two-stage reconstruction. Prophylactic antibiotics and drains were used in all cases. Median mastectomy weight was 308 g (interquartile range (IQR) 205-363 g). Median implant volume was 350 ml (IQR 275-400 ml). Twenty percent (N = 6) had minor complications within 3 months. Forty-two percent (N = 8) of patients had complete resorption of Veritas® (50%, N = 15 reconstructions) with “bottoming out” of implants requiring revision surgery. Ten percent (N = 3) developed capsular contracture following radiotherapy and 3.3% (N = 1) had implant loss due to pain following postoperative infection. Product outcomes were reported to the manufacturers.Conclusions: Veritas® collagen matrix has a comparable immediate postoperative complication rate when compared to other acellular dermal matrix. However, the long-term resorption rate in this series is high resulting in frequent correctional surgery.Level of Evidence: Level III, risk/prognostic study. [ABSTRACT FROM AUTHOR]

- Abstract
Abstract: Effective biomaterial options for tissue repair and regeneration are limited. Current biologic meshes are derived from different tissue sources and are generally sold as decellularized tissues. This work evaluated two collagen based bioengineered constructs and a commercial product in a model of abdominal full thickness defect repair. To prepare the bioengineered construct, collagen type 1 from porcine skin was isolated using an acid solubilization method. After purification, the collagen was formed into collagen sheets that were physically bonded to form a mechanically robust construct that was subsequently laser micropatterned with pores as a means to promote tissue integration (collagen only construct). A second engineered construct consisted of the aforementioned collagen construct embedded in an RGD‐functionalized alginate gel that serves as a bioactive interface (collagen‐alginate construct). The commercial product is a biologic mesh derived from bovine pericardium (Veritas
® ). We observed enhanced vascularization in the midportion of the engineered collagen‐alginate construct 2 weeks after implantation. Overall, the performance of the bioengineered constructs was similar to that of the commercial product with comparable integration strength at 8 weeks. Bioengineered constructs derived from monomeric collagen demonstrate promise for a variety of load bearing applications in tissue engineering. © 2017 Wiley Periodicals, Inc.

- Abstract
Background Accounting for daily mobility allows assessment of multiple exposure to environments. This study compares spatial data obtained (i) from an interactive map-based questionnaire on regular activity locations (VERITAS) and (ii) from GPS tracking. Methods 234 participants of the RECORD GPS Study completed the VERITAS questionnaire and wore a GPS tracker for 7 days. Analyses illustrate the spatial match between both datasets. Results For half of the sample, 85.5% of GPS data fell within 500 m of a VERITAS location. The median minimum distance between a VERITAS location and a GPS coordinate ranged from 0.4 m for home to slightly over 100 m for a recreational destination. Conclusions There is a spatial correspondence between destinations collected through VERITAS and 7-day GPS tracking. Both collection methods offer complementary ways to assess daily mobilities, useful to study environmental determinants of health and health inequities. [ABSTRACT FROM AUTHOR]

Children's independent mobility (IM) lacks a standardised definition and measurement protocol. Interactive mapping applications can capture geographically defined mobility data. In this study of 219 children, independent parental licences (IM Licence) and allowances to travel to certain locations unsupervised (IM Index) were collected through a questionnaire, and compared to IM-roaming areas derived from the Visualisation and Evaluation of Route Itineraries, Travel Destinations, and Activity Spaces (VERITAS-IM) mapping application. Significant relationships were found between the VERITAS-IM-derived measures and traditional measures of IM (IM Licence and IM Index). Results suggest the perceived degree of children's IM is heavily dependent on the assessment method and a combination of methods should be considered. [ABSTRACT FROM AUTHOR]

This binary underwent an exceptionally bright X-ray outburst from 2018 March to October, showing evidence of a non-thermal particle population through its radio emission during this whole period. The combined results of 59.5 h of observations of the MAXI J1820+070 outburst with the H.E.S.S., MAGIC and VERITAS experiments at energies above 200 GeV are presented, together with Fermi-LAT data between 0.1 and 500 GeV, and multiwavelength observations from radio to X-rays. Gamma-ray emission is not detected from MAXI J1820+070, but the obtained upper limits and the multiwavelength data allow us to put meaningful constraints on the source properties under reasonable assumptions regarding the non-thermal particle population and the jet synchrotron spectrum. In particular, it is possible to show that, if a high-energy (HE) gamma-ray emitting region is present during the hard state of the source, its predicted flux should be at most a factor of 20 below the obtained Fermi-LAT upper limits, and closer to them for magnetic fields significantly below equipartition. During the state transitions, under the plausible assumption that electrons are accelerated up to similar to 500 GeV, the multiwavelength data and the gamma-ray upper limits lead consistently to the conclusion that a potential HE and very-HE gamma-ray emitting region should be located at a distance from the BH ranging between 10(11) and 10(13) cm.

Very-high-energy (VHE) gamma-ray astronomy can provide insight in to the origin of cosmic rays. The Cygnus arm of the Galaxy is a well studied region and has been shown to have active sources of particle acceleration. VERITAS (Very Energetic Radiation Imaging Telescope Array System) is an array of four 12 meter diameter imaging atmospheric Cherenkov telescopes located at the Fred Lawrence Whipple Observatory in southern Arizona. From 2007 through 2012 VERITAS observed the Cygnus region for nearly 300 hours from 67� to 82� in Galactic longitude and from -1� to 4� in Galactic latitude. The survey and followup observations detected four sources: VER J2031+415, VER J2019+407, VER J2016+317, and VER J2019+368. The Fermi Large Area Telescope (Fermi-LAT) is a satellite gamma-ray telescope operating in the high-energy gamma-ray regime. The emission detected by the Fermi-LAT can provide insight into the nature of these sources and guide targeted followup observations in the region. We have reanalyzed the VERITAS data with updated VERITAS analysis and completed an analysis of over seven years of Fermi-LAT data in the region. We have discovered Fermi-LAT emission associated with VER J2031+415 strengthening its interpretation as a pulsar wind nebula, the SNR nature of VER J2019+407 has been confirmed by this study, and VER J2016+317 has been confirmed to be associated with the pulsar wind nebula CTB 87 rather than with a blazar source located at the same position. The Cygnus region is observed to be a particularly bright region of the Galaxy with both very-high-energy and high-energy gamma-ray experiments. These results motivate continued study of the region with VERITAS, as well as with current and future experiments such as HAWC and CTA.

米国で誕生したチアリーディングの歴史を概観し、それが日本に伝わる中で、一大学のサークルがチアダンスを通して全米大会出場を目標にさまざまな挑戦を行っていく過程とそこで演じられた作品を分析する方法を考察していく。チアリーディングの始まりは、1800年代後半の米国の大学スポーツに見ることができる。やがてグローバルな規模で展開していく中で、1980年代から日本において競技としてのチアリーディング、パフォーマンスチアの世界が始まっていった。全国の高校・大学でサークル活動が活発化していく中で、2007年4 月に尚美学園大学女子チアダンス部が誕生した。チーム名のVERITASベリタスは、真理を意味するラテン語で、ヨハネ福音書の言葉に由来する。米国では大学スポーツを統括する組織として、1910年に全米大学アスレチック協会NationalCollegiate Athletic Association（NCAA）が設立された。NCAAは、学生アスリートを競技者である前に学生であるとする立場を明確にしており、学業成績の管理にも力を入れている。VERITASもこの趣旨に沿った活動を心掛けてきた。大会での演技を記録する方法としては、映像によるものが最も理解しやすく、かつ、記録に残しやすい。しかし、そこには作品のストーリー、ジャッジによる評価、コメントなど言語化されたデータを合わせて記録することは困難である。身体の動きを客観的に記録することに留まらず、それが全体のコンテクストの中でどのような意味を持つか、演じる側の解釈とともにジャッジによる解釈も言語化することにより、これまでの大会演技を記録する試みを行った。本稿では、海外大会で演じた4つの作品研究を取り上げる。, This paper provides an overview of the history of cheerleading in the United States and analyzes the process by which a Japanese university team competes in various competitions with the goal of participating in collegiate championships held in the United States. Cheerleading became a part of American college sports in the late 1800s. With globalization, cheerleading and performance cheers spread to Japan in the 1980s. The activities of cheerleading teams in high schools and universities across Japan soon became widespread, and the Shobi University Women’s Cheer Dance Team was established in April 2007. The cheer dancing team was named VERITAS, a Latin word meaning “truth,” derived from the Bible. VERITAS follows the motto of the National Collegiate Athletic Association（ NCAA） established in 1910 in the United States, which is an organization that oversees college sports. According to the NCAA, student athletes are students first and then athletes; thus, it sets strict academic standards for student athletes and member universities to manage academic performance. The performances at the competitions are best recorded as videos, but verbalized data, such as the narration of the work, evaluation by judges, and comments, are difficult to record. Recording should cover not only physical movements but also help analyze what movements mean in the overall context. Thus, in this study, performances in previous competitions were recorded by verbalizing the interpretation of both the judges and the performer. The study provides an overview of four performances that were part of overseas competition.

Cosmological and astrophysical observations suggest that 85% of the total matter of the Universe is made of Dark Matter (DM). However, its nature remains one of the most challenging and fundamental open questions of particle physics. Assuming particle DM, this exotic form of matter cannot consist of Standard Model (SM) particles. Many models have been developed to attempt unraveling the nature of DM such as Weakly Interacting Massive Particles (WIMPs), the most favored particle candidates. WIMP annihilations and decay could produce SM particles which in turn hadronize and decay to give SM secondaries such as high energy γ rays. In the framework of indirect DM search, observations of promising targets are used to search for signatures of DM annihilation. Among these, the dwarf spheroidal galaxies (dSphs) are commonly favored owing to their expected high DM content and negligible astrophysical background. In this work, we present the very first combination of 20 dSph observations, performed by the Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS collaborations in order to maximize the sensitivity of DM searches and improve the current results. We use a joint maximum likelihood approach combining each experiment’s individual analysis to derive more constraining upper limits on the WIMP DM self-annihilation cross-section as a function of DM particle mass. We present new DM constraints over the widest mass range ever reported, extending from 5 GeV to 100 TeV thanks to the combination of these five different γ-ray instruments., PoS: Proceedings of Science, 395, ISSN:1824-8039, Proceedings of 37th International Cosmic Ray Conference

The discovery of gravitational waves, high-energy neutrinos or the very-high-energy counterpart of gamma-ray bursts has revolutionized the high-energy and transient astrophysics community. The development of new instruments and analysis techniques will allow the discovery and/or follow-up of new transient sources. We describe the prospects for the Cherenkov Telescope Array (CTA), the next-generation ground-based gamma-ray observatory, for multi-messenger and transient astrophysics in the decade ahead. CTA will explore the most extreme environments via very-high-energy observations of compact objects, stellar collapse events, mergers and cosmic-ray accelerators., Submitted to ASTRONET roadmap on behalf of the CTA consortium

ASTRONOMICAL observations , *CHERENKOV radiation , *PHOTOMULTIPLIERS , *TELESCOPES , *GAMMA rays , *PHOTODETECTORS - Abstract
Imaging atmospheric Cherenkov telescopes (IACTs) are equipped with sensitive photomultiplier tube (PMT) cameras. Exposure to high levels of background illumination degrades the efficiency of and potentially destroys these photo-detectors over time, so IACTs cannot be operated in the same configuration in the presence of bright moonlight as under dark skies. Since September 2012, observations have been carried out with the VERITAS IACTs under bright moonlight (defined as about three times the night-sky-background (NSB) of a dark extragalactic field, typically occurring when Moon illumination > 35%) in two observing modes, firstly by reducing the voltage applied to the PMTs and, secondly, with the addition of ultra-violet (UV) bandpass filters to the cameras. This has allowed observations at up to about 30 times previous NSB levels (around 80% Moon illumination), resulting in 30% more observing time between the two modes over the course of a year. These additional observations have already allowed for the detection of a flare from the 1ES 1727 + 502 and for an observing program targeting a measurement of the cosmic-ray positron fraction. We provide details of these new observing modes and their performance relative to the standard VERITAS observations. [ABSTRACT FROM AUTHOR]

Background Even though meshes and matrices are widely used in breast reconstruction, there is little high‐quality scientific evidence for their risks and benefits. The aim of this study was to compare first‐year surgical complication rates in implant‐based immediate breast reconstruction with a biological mesh with that of a synthetic mesh, in the same patient. Methods This study is a clinical, randomized, prospective trial. Patients operated on with bilateral mastectomy and immediate breast reconstruction were randomized to biological mesh on one side and synthetic mesh on the other side. Results A total of 48 breasts were randomized. As the synthetically and the biologically reconstructed breasts that were compared belonged to the same woman, systemic factors were exactly the same in the two groups. The most common complication was seroma formation with a frequency of 38% in the biological group and 3.8% in the synthetical group (p = .011). A higher frequency of total implant loss could be seen in the biologic mesh group (8.5% vs. 2%), albeit not statistically significant (p = .083). Conclusions In the same patient, a synthetic mesh seems to yield a lower risk for serious complications, such as implant loss, than a biological mesh.

Cosmic-ray transport in astrophysical environments is often dominated by the diffusion of particles in a magnetic field composed of both a turbulent and a mean component. This process, which is two-fold turbulent mixing in that the particle motion is stochastic with respect to the field lines, needs to be understood in order to properly model cosmic-ray signatures. One of the most important aspects in the modeling of cosmic-ray diffusion is that fully resonant scattering, the most effective such process, is only possible if the wave spectrum covers the entire range of propagation angles. By taking the wave spectrum boundaries into account, we quantify cosmic-ray diffusion parallel and perpendicular to the guide field direction at turbulence levels above 5% of the total magnetic field. We apply our results of the parallel and perpendicular diffusion coefficient to the Milky Way. We show that simple purely diffusive transport is in conflict with observations of the inner Galaxy, but that just by taking a Galactic wind into account, data can be matched in the central 5 kpc zone. Further comparison shows that the outer Galaxy at $>5\,$kpc, on the other hand, should be dominated by perpendicular diffusion, likely changing to parallel diffusion at the outermost radii of the Milky Way., Published in Springer Nature Applied Sciences

Astronomy and astrophysics 658, A83 (2022). doi:10.1051/0004-6361/202142275, Context. The response of imaging air Cherenkov telescopes to incident $γ$-ray-initiated showers in the atmosphere changes as the telescopes age due to exposure to light and weather. These aging processes affect the reconstructed energies of the events and $γ$-ray fluxes.Aims. This work discusses the implementation of signal calibration methods for the Very Energetic Radiation Imaging Telescope Array System (VERITAS) to account for changes in the optical throughput and detector performance over time. Methods. The total throughput of a Cherenkov telescope is the product of camera-dependent factors, such as the photomultiplier tube gains and their quantum efficiencies, and the mirror reflectivity and Winston cone response to incoming radiation. This document summarizes different methods to determine how the camera gains and mirror reflectivity have evolved over time and how we can calibrate this changing throughput in reconstruction pipelines for imaging air cherenkov telescopes. The implementation is validated against seven years of observations with the VERITAS telescopes of the Crab Nebula, which is a reference object in very-high-energy astronomy.Results. Regular optical throughput monitoring and the corresponding signal calibrations are found to be critical for the reconstruction of extensive air shower images. The proposed implementation is applied as a correction to the signals of the photomultiplier tubes in the telescope simulation to produce fine-tuned instrument response functions. This method is shown to be effective for calibrating the acquired $γ$-ray data and for recovering the correct energy of the events and photon fluxes. At the same time, it keeps the computational effort of generating Monte Carlo simulations for instrument response functions affordably low., Published by EDP Sciences, Les Ulis

Any further distribution of this work must maintain attribution to the author(s) and the title of the work, journal citation and DOI., We provide an updated assessment of the power of the Cherenkov Telescope Array (CTA) to search for thermally produced dark matter at the TeV scale, via the associated gamma-ray signal from pair-annihilating dark matter particles in the region around the Galactic centre. We find that CTA will open a new window of discovery potential, significantly extending the range of robustly testable models given a standard cuspy profile of the dark matter density distribution. Importantly, even for a cored profile, the projected sensitivity of CTA will be sufficient to probe various well-motivated models of thermally produced dark matter at the TeV scale. This is due to CTA's unprecedented sensitivity, angular and energy resolutions, and the planned observational strategy. The survey of the inner Galaxy will cover a much larger region than corresponding previous observational campaigns with imaging atmospheric Cherenkov telescopes. CTA will map with unprecedented precision the large-scale diffuse emission in high-energy gamma rays, constituting a background for dark matter searches for which we adopt state-of-the-art models based on current data. Throughout our analysis, we use up-to-date event reconstruction Monte Carlo tools developed by the CTA consortium, and pay special attention to quantifying the level of instrumental systematic uncertainties, as well as background template systematic errors, required to probe thermally produced dark matter at these energies. © 2021 The Author(s)., We gratefully acknowledge financial support from the following agencies and organisations: State Committee of Science of Armenia, Armenia; The Australian Research Council, Astronomy Australia Ltd, The University of Adelaide, Australian National University, Monash University, The University of New South Wales, The University of Sydney, Western Sydney University, Australia; Federal Ministry of Education, Science and Research, and Innsbruck University, Austria; Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPq), Fundacao de Amparo a Pesquisa do Estado do Rio de Janeiro (FAPERJ), Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP), Ministry of Science, Technology, Innovations and Communications (MCTIC), and Instituto Serrapilheira, Brasil; Ministry of Education and Science, National RI Roadmap Project DO1-153/28.08.2018, Bulgaria; The Natural Sciences and Engineering Research Council of Canada and the Canadian Space Agency, Canada; CONICYT-Chile grants CATA AFB 170002, ANID PIA/APOYO AFB 180002, ACT 1406, FONDECYT-Chile grants, 1161463, 1170171, 1190886, 1171421, 1170345, 1201582, Gemini-ANID 32180007, Chile; Croatian Science Foundation, Rudjer Boskovic Institute, University of Osijek, University of Rijeka, University of Split, Faculty of Electrical Engineering, Mechanical Engineering and Naval Architecture, University of Zagreb, Faculty of Electrical Engineering and Computing, Croatia; Ministry of Education, Youth and Sports, MEYS LM2015046, LM2018105, LTT17006, EU/MEYS CZ.02.1.01/0.0/0.0/16_013/0001403, CZ.02.1.01/0.0/0.0/18_046/0016007 and CZ.02.1.01/0.0/0.0/16_019/0000754, Czech Republic; Academy of Finland (grant nr.317636, 320045, 317383 and 320085), Finland; Ministry of Higher Education and Research, CNRS-INSU and CNRS-IN2P3, CEA-Irfu, ANR, Regional Council Ile de France, Labex ENIGMASS, OSUG2020, P2IO and OCEVU, France; Max Planck Society, BMBF, DESY, Helmholtz Association, Germany; Department of Atomic Energy, Department of Science and Technology, India; Istituto Nazionale di Astrofisica (INAF), Istituto Nazionale di Fisica Nucleare (INFN), MIUR, Istituto Nazionale di Astrofisica (INAF-OABRERA) Grant Fondazione Cariplo/Regione Lombardia ID 2014-1980/RST_ERC, Italy; ICRR, University of Tokyo, JSPS, MEXT, Japan; Netherlands Research School for Astronomy (NOVA), Netherlands Organization for Scientific Research (NWO), Netherlands; University of Oslo, Norway; Ministry of Science and Higher Education, DIR/WK/2017/12, the National Centre for Research and Development and the National Science Centre, UMO-2016/22/M/ST9/00583, Poland; Slovenian Research Agency, grants P1-0031, P1-0385, I0-0033, J1-9146, J1-1700, N1-0111, and the Young Researcher program, Slovenia; South African Department of Science and Technology and National Research Foundation through the South African Gamma-Ray Astronomy Programme, South Africa; The Spanish Ministry of Science and Innovation and the Spanish Research State Agency (AEI) through grants AYA2016-79724-C4-1-P, AYA2016-80889-P, AYA2016-76012-C3-1-P, BES-2016-076342, ESP2017-87055-C2-1-P, FPA2017-82729-C6-1-R, FPA2017-82729-C6-2-R, FPA2017-82729-C6-3-R, FPA2017-82729-C6-4-R, FPA2017-82729-C6-5-R, FPA2017-82729-C6-6-R, PGC2018-095161-B-I00, PGC2018-095512-B-I00; the \Centro de Excelencia Severo Ochoa"program through grants no.

For decades, searches for electroweak-scale dark matter (DM) have been performed without a definitive detection. This lack of success may hint that DM searches have focused on the wrong mass range. A proposed candidate beyond the canonical parameter space is ultra-heavy DM (UHDM). In this work, we consider indirect UHDM annihilation searches for masses between 30 TeV and 30 PeV, extending well beyond the unitarity limit at $\sim$100 TeV, and discuss the basic requirements for DM models in this regime. We explore the feasibility of detecting the annihilation signature, and the expected reach for UHDM with current and future Very-High-Energy (VHE; $>$ 100 GeV) $\gamma$-ray observatories. Specifically, we focus on three reference instruments: two Imaging Atmospheric Cherenkov Telescope arrays, modeled on VERITAS and CTA-North, and one Extended Air Shower array, motivated by HAWC. With reasonable assumptions on the instrument response functions and background rate, we find a set of UHDM parameters (mass and cross section) for which a $\gamma$-ray signature can be detected by the aforementioned observatories. We further compute the expected upper limits for each experiment. With realistic exposure times, the three instruments can probe DM across a wide mass range. At the lower end, it can still have a point-like cross section, while at higher masses the DM could have a geometric cross section, indicative of compositeness.

The landscape of high- and ultra-high-energy astrophysics has changed in the last decade, largely due to the inflow of data collected by large-scale cosmic-ray, gamma-ray, and neutrino observatories. At the dawn of the multimessenger era, the interpretation of these observations within a consistent framework is important to elucidate the open questions in this field. CRPropa 3.2 is a Monte Carlo code for simulating the propagation of high-energy particles in the Universe. This version represents a major leap forward, significantly expanding the simulation framework and opening up the possibility for many more astrophysical applications. This includes, among others: efficient simulation of high-energy particles in diffusion-dominated domains, self-consistent and fast modelling of electromagnetic cascades with an extended set of channels for photon production, and studies of cosmic-ray diffusion tensors based on updated coherent and turbulent magnetic-field models. Furthermore, several technical updates and improvements are introduced with the new version, such as: enhanced interpolation, targeted emission of sources, and a new propagation algorithm (Boris push). The detailed description of all novel features is accompanied by a discussion and a selected number of example applications., 32 pages, 9 figures

Listed, in Apollodore’s Library, among the founding myths, the story of Acteon, the over-inquisitive hunter, knew, with the Latins, thanks to Ovid, a particularly rich fortune. In the second century, Apuleius recapture the theme in his Metamorphosis and made his own the Ovidian aesthetics of perpetual motion and the fickleness of appearances, but somewhat distorted its significance by orienting it towards a mystique of Beauty. Combining classical aesthetics and Ovidian heritage, he made of Acteon’s reflection in the water of the spring the revealer of the sacrilege. Art thus captures the globality of the Real by combining direct perception and its reflection, thereby making the truth emerge, that is Beauty, in the most idealistic line of platonism.

Dwarf spheroidal galaxies (dSphs) are ideal targets for Dark Matter (DM) indirect searches due to their high DM content and their negligible expected astrophysical background. In this presentation, we report on the combined analysis of the observations of 20 dSphs by Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS collaborations in the search for DM, focusing on the Weakly Interacting Massive Particles (WIMPs) scenario. The combined analysis allows us to maximize the sensitivity by combining individual data sets from all five experiments for which the energy ranges of the search overlap. New constraints, spanning a range of DM masses from 5 GeV to 100 TeV, on the velocity-weighted cross section for DM self annihilation will be presented.

37th International Cosmic Ray Conference, ICRC 2021, Berlin, online, Germany, 12 Jul 2021 - 23 Jul 2021; Proceedings of Science / International School for Advanced Studies (ICRC2021), 822 (2021). doi:10.22323/1.395.0822, Ground-based $\gamma$-ray observatories, such as the VERITAS array of imaging atmospheric Cherenkov telescopes, provide insight into very-high-energy (VHE, $\mathrm{E}>100\,\mathrm{GeV}$) astrophysical transient events. Examples include the evaporation of primordial black holes, gamma-ray bursts and flaring blazars. Identifying such events with a serendipitous location and time of occurrence is difficult. Thus, employing a robust search method becomes crucial. An implementation of a transient detection method based on deep-learning techniques for VERITAS will be presented. This data-driven approach significantly reduces the dependency on the characterization of the instrument response and the modelling of the expected transient signal. The response of the instrument is affected by various factors, such as the elevation of the source and the night sky background. The study of these effects allows enhancing the deep learning method with additional parameters to infer their influences on the data. This improves the performance and stability for a wide range of observational conditions. We illustrate our method for an historic flare of the blazar BL Lac that was detected by VERITAS in October 2016. We find a promising performance for the detection of such a flare in timescales of minutes that compares well with the VERITAS standard analysis., Published by SISSA, Trieste
