description: Effective nuclear densities probed by kaon- and anti-kaon-nucleus systems are studied theoretically both for bound and low energy scattering states. As for the anti-kaon bound states, we investigate kaonic atoms. We find that the effective density depends on the atomic states significantly and we have the possibility to obtain the anti-kaon properties at various nuclear densities by observing the several kaonic atom states. We also find the energy dependence of the probed density by kaon and anti-kaon scattering states. We find that the study of the effective nuclear density will help to find the proper systems to investigate the meson properties at various nuclear densities.

These data form part of the early commissioning observations for the e-MERLIN interferometer and a pilot for the e-MERLIN legacy program eMERGE. A total of 17 sources were detected with S/N>3. These observations provide unique information on the radio source morphology at sub-arcsec scales. For twelve of these sources, deeper 1.4 GHz MERLIN+VLA observations at the same spatial resolution are available, allowing radio spectral indices to be derived for ten sources on sub-arcsec angular scales. Via analysis of the spectral indices and radio morphologies, these sources have been identified as AGN cores in moderate-to-high redshift (1

description: This research aims to investigate the cloud security metrics by exploring the existing frameworks, integrated approaches and quantitative measurements to enhance overall security in cloud environments. This study explains several established frameworks and standards, such as the CSA Cloud Controls Matrix, NIST SP 800-53 and ISO/IEC 27001, which are important in guiding organizations towards strong security practices. Moreover, a qualitative research method has been used in this research study, conducting a literature review of past studies on the same topic. The challenges and limitations regarding cloud security have also been mentioned in this research study, which is helpful for future researchers to explore in detail and develop stronger strategies for enhancing cloud security as a whole. This research study states that the emerging threats and technologies related to cloud security must be explored continuously to develop a detailed understanding of cloud security measures.

Effects of H2 coating of grains on depletion of molecular species

Publisher: name: arXiv
Year: 2012
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Physical conditions in dense and cold regions of interstellar clouds favour the formation of ice mantles on the surfaces of interstellar grains. It is predicted that most of the gaseous species heavier than H2 or He will adsorb onto the grains and will disappear from the gas-phase, changing its chemistry, within 10^9/n_H years. Nonetheless, many molecules in molecular clouds are not completely depleted in timescales of 10^5 yr. Several speculative mechanisms have been proposed to explain why molecules stay in the gas phase, but up to now none are fully convincing. At the same time, these mechanisms are not mutually exclusive and we can still explore the effects of other possible processes. We speculate on the consequences of H2 coating of grains on the evaporation rates of adsorbed species. More experiments and simulations are needed to calculate the evaporation rate Eevap(X-H2).

description: Einstein introduced Cosmological Constant in his field equations in an ad hoc manner. Cosmological constant plays the role of vacuum energy of the universe which is responsible for the accelerating expansion of the universe. To give theoretical support it remains an elusive goal to modern physicists. We provide a prescription to obtain cosmological constant from the phase transitions of the early universe when topological defects, namely monopole might have existed.
title: Comparison of 2.5D finite element formulations with perfectly matched layers for solving open axisymmetric electromagnetic cavity problems
Creators: name: Schnaubelt, Erik
name: De Gersem, Herbert
name: Marsic, Nicolas
Publisher: name: John Wiley & Sons
Year: 2023

description: Axial symmetry in time‐harmonic electromagnetic wave problems can be exploited by considering a Fourier expansion along the angular direction, reducing fully three‐dimensional computations to two‐dimensional ones on an azimuthal cross section. While this transition leads to a significant decrease in computational effort, it introduces additional difficulties, which necessitate appropriate finite element (FE) formulations. By combining the latter with perfectly matched layers (PML), open problems can be considered. In this work, we compare and discuss the performance of different combinations of axisymmetric FE formulations and PMLs, using a dielectric sphere in open space as a test case. As an application example, a superconducting Fabry–Pérot photon trap is considered.

description: My technical/professional writing courses and experiences at Utah State University have taught me the importance of clear accessible writing and layout. As a senior honors student, I wished to practice the readability and accessibility skills I have acquired by creating a portfolio of technical writing projects. This would serve as a helpful instrument of practice for my entry into the technical writing profession. The portfolio includes three different projects: a non-periodic publication (Boise State Classroom Technology Bulletin), a newsletter (EIMCO Carrousel System Operators' Newsletter) and a procedures manual (Petroglyph Magazine Procedures). The written narrative that accompanies this portfolio summarizes the justification for the projects I chose to analyze, including the criteria I analyzed them against; a background of each project; the changes I made to increase accessibility and why; and a conclusion exploring how and if goals were attained.
title: A Functionalist Approach to Emotions
Creators: name: Guillaumot, Julien
Publisher: name: Utah State University
Year: 1995

description: There are at least two ways in which emotions can be conceptualized. The first, and most widespread, one is the cognitive approach which implies the presence of internal processes or psychological mechanisms. The cognitive approach says that emotions are the result of evolutionary processes. The second approach is behaviorological. It states that emotions are learned and are nothing more than behaviorological and physiological events. Both approaches, even if different, have an extremely important effect on our world because they may help make societal decisions and therefore manage our environment in a better way. As we will see, though, authorities do not always look at the research before making critical judgements.

My goal in this paper is twofold: First it is to review several lines of research on how certain emotions -namely guilt and shame- "evolved":. Second, it is to show that, unfortunately, the general public and city officials often make decisive judgements without referring to the research that has been done on the subject. After introducing the main theories of emotions and describing the behaviorological perspective, I will comment on the hasty and unwise decisions that are being make nationwide to reduce the rate of recidivism of criminals. But before I present the applied part, and in order for the reader to understand better the different theories of emotions, let me introduce you to some lines of research.

title: Formen deutscher und finnischer zivilgesellschaftlicher Gegenredeinitiativen in sozialen Medien
Creators: name: Ylönen, Sabine
Publisher: name: Universitäts- und Landesbibliothek Darmstadt
Year: 2023

description: Als fünfte Gewalt eröffnen soziale Medien neue zivilgesellschaftliche Partizipationsmöglichkeiten, denen ein großes Demokratisierungspotenzial zugesprochen wird. Andererseits bergen sie auch Risiken für demokratische Gesellschaften, wie die Verbreitung von Hassreden und Desinformationen gezeigt haben. Da sich soziale Medien rasant weiterentwickeln, hinken Gesetzgebung und der Ausbau von Strafverfolgungsressourcen unweigerlich hinterher. Darüber hinaus sind nicht alle Hassreden und demokratiegefährdenden Diskurse strafbar und widersprechen auch nicht immer den Gemeinschaftsstandards der Plattformen. Gegenreden der Zivilgesellschaft können den Ton in den Kommentarspalten sozialer Medien verbessern und dazu beitragen, die Leser über wissenschaftlich anerkannte Fakten aufzuklären. In dieser kontrastiven Studie wurde untersucht, ob es kulturgebundene Unterschiede in der Einstellung zu Gegenrede gibt. Neben semiethnografischen teilnehmenden Beobachtungen von zwei deutschen und zwei finnischen Gegenredeinitiativen wurden über tausend ihrer Beiträge für eine systematische Analyse ihrer Kommunikationsstrategien gesammelt. Kulturgebundene Unterschiede in der Einstellung zu Gegenrede sind unter anderem an unterschiedlichen Motiven für die Gründung der Initiativen (systematisch geplant vs. spontan), am Management (hierarchisch oder heterarchisch) und an gesellschaftlicher Wertschätzung (gewährte oder fehlende Auszeichnungen und Medienpräsenz) festzumachen. Gegenrede wurde als reaktive oder proaktive Antwort der Zivilgesellschaft auf die Verschiebung des Sagbarkeitsfeldes in Richtung einer Verrohung von Sprache und Normalisierung demokratiegefährdender Diskurse definiert. Mit vorliegender Studie konnte gezeigt werden, dass Gegenredeinitiativen aktions- oder diskussionsorientiert sein können. In jedem Fall bieten sie Peer Support und Möglichkeiten gemeinsamen Lernens. Humor dient als Ventil, und humorvolle Gegenrede zieht Follower und Mitglieder in beiden Ländern an.

title: Perspektiven migrationsbedingt mehrsprachiger Lehramtsstudierender auf Ansätze der Mehrsprachigkeitsorientierung in ihrer eigenen Schulzeit, im Studium und im eigenen Unterricht
Creators: name: Maahs, Ina-Maria
Publisher: name: Universitäts- und Landesbibliothek Darmstadt
Year: 2023

description: An Lehrkräfte mit Migrationshintergrund werden in der aktuellen Bildungsdebatte oft Erwartungen gestellt, die sie unabhängig von der Qualifikation nur aufgrund bestimmter (zugeschriebener) (sprach-)biografischer Erfahrungen erfüllen sollen. Dazu gehört die Idee, dass mehrsprachig sozialisierte Lehrkräfte automatisch einen mehrsprachigkeitsorientierten Unterricht gestalten. Dieser Beitrag hinterfragt solche Prämissen kritisch und präsentiert die Ergebnisse einer qualitativen Befragung migrationsbedingt mehrsprachiger Lehramtsstudierender zu ihren Erfahrungen mit Mehrsprachigkeit im deutschen Bildungssystem sowie ihrer Haltung zu Mehrsprachigkeitsorientierung im eigenen Unterricht. Dabei werden (neo-)linguizistische Diskriminierungsprozesse offengelegt, die die angehenden Lehrkräfte im eigenen Unterricht vermeiden wollen. Gleichzeitig zeigen sich die Studierenden skeptisch gegenüber einer mehrsprachigkeitsdidaktischen Gestaltung des eigenen Unterrichts.

description: Hochpräzise Atominterferometrie mit Bose-Einstein-Kondensaten hat das Potential Tests fundamentaler Physik mit bisher unerreichter Genauigkeit durchzuführen, sowie die Entwicklung neuartiger Sensoren für die Erdbeobachtung zu initiieren. Insbesondere schaffen Messungen mit Atominterferometern im Weltraum den Rahmen für Tests der allgemeinen Relativitätstheorie, der Suche nach dunkler Energie, satellitengestützter Erdbeobachtung und der Detektion von Gravitationswellen in einem auf der Erde nicht erreichbaren Regime. Die technischen Ansprüche einer Weltraummission unterscheiden sich grundlegend von denen eines Laboraufbaus. Neben einer Optimierung bezüglich der Masse, der Leistungsaufnahme und des Volumens muss die Apparatur autonom und wartungsfrei arbeiten, sowie robust gegen Vibrationen und Beschleunigungen während des Aufstiegs und Wiedereintritts in die Atmosphäre sein. Mit der MAIUS-1 Mission ist es am 23.01.2017 zum ersten Mal gelungen Bose- Einstein-Kondensate im Weltraum zu erzeugen. Erstmals wurde eine solche Apparatur an Bord einer Höhenforschungsrakete betrieben und hat Schlüsselmethoden für präzise Materiewelleninterferometrie demonstriert. In den insgesamt 13 Minuten des Parabelfluges befand sich die Nutzlast sechs Minuten lang über bei einer Höhe von 100km unter Mikrogravitationsbedingungen. Während des Starts und Aufstiegs konnten für eine Minute Experimente zum Kühlen und Fangen kalter atomarer Ensembles in dieser hochdynamischen Umgebung durchgeführt werden. In der Mikrogravitationsphase wurde der Phasenübergang zum Bose-Einstein- Kondensat mit mehr als 105 Rubidiumatomen untersucht. Die Präparation der ultrakalten Ensembles für die Interferometrie wurde charakterisiert und autonom vom System optimiert, wobei sich die Reproduzierbarkeit aller Prozesse zur Kühlung zeigte. Des Weiteren wurden Zwei-Photonen-Prozesse genutzt, um die Materiewelle in die Superposition von Impulszuständen zu überführen und zur Interferenz zu bringen. Somit konnte die Kohärenz über die gesamte Ausdehnung der Kondensate nachgewiesen werden. Mit jeder Licht-Materie-Wechselwirkung wurde eine zusätzliche Phasenmodulation auf die Materiewelle aufgeprägt. Diese Struktur wurde nach einer freien Evolutionszeit in der räumlichen Dichteverteilung sichtbar und konnte für weitere Analysen verschiedener Spinorkomponenten des Ensembles verwendet werden. Die Erkenntnisse zur Präparation der ultrakalten Ensembles und zur Interferometrie im Weltraum wie auch die entwickelten Technologien ermöglichen künftige Missionen.
title: An Analysis of Isenberg's Aesthetic Theory and its Application to the Works of Monet and Smokey
Creators: name: Gross, Tracee Elizabeth
Publisher: name: Utah State University
Year: 1995

description: Aesthetics is a branch of philosophy, which attempts to define art using a set of purported characteristics that, when applied to particular pieces, will aid in making discriminations between art and non-art. Aesthetics also traditionally examines the creation, appreciation, and criticism of art. Theories of aesthetics are constructed to assist one in making judgments as to whether or not a piece is art or is beautiful. Ideally, theories serve two primary tasks. The first is to provide an explanation, which will aid in separating out those items not covered in the scope of the theory. Also, theories are used as a vehicle for prediction. Using theories, one can determine in advance whether a piece will be classified as art or beautiful under its formulation.

Subjects: subject: Law
subject: FOS: Law

description: The efficiency and effectiveness of judicial systems have become one of the main points of interest in public administration, due to the beneficial effects of an efficient judicial system on economic growth. It is rightly said that ‘Justice delayed is justice denied’ and hence it is expected that the judiciary in any country should provide efficient and timely relief to the people who come to its courts. Indian Institute of Management Kashipur (IIM Kashipur) conducted this study during 2015-2017 to develop possible performance measurement indicators for Subordinate Courts in the form of action based research. The overall research design follows a consultative process with the ‘stakeholders’ (lawyers, judges, researchers and academics) in two states namely Uttar Pradesh and Uttarakhand. The discussions with the stakeholders yielded a broad set of performance indicators: Infrastructure, Institution-Disposition Ratio, Quality of Judgment, Number of Adjournments, Encouragement of Alternative dispute resolution (ADR) and Training of Judicial Officers. During the study, the stakeholders also debated whether performance evaluation of courts should also take into account the performance of all associated staff and availability of conducive infrastructure or should only focus on the performance of the individual judge.

We then discuss ensembleaverages of such theories over their moduli space, and obtain a modular form associated withthe quadratic form and an element of the discriminant group. The modular form can bewritten as a Poincar´e series, which contains novel invariants of lens spaces and suggests theinterpretation of the holographic bulk as a theory of anyons.

description: On the way to fully autonomous machine tools it is essential to independently select suitable process parameters and adapt them on-the-fly to the appropriate process conditions in a self-controlled manner. Such systems require complex physical process models and are usually limited to feed and spindle speed adaption during the milling process. This paper introduces a new approach enabling machines during the milling process to learn which parameters lead to a stable process with maximum productivity and to adjust them autonomously. It is shown that this approach enables the machine tool to independently find stable process parameters with maximum productivity.

description: Using archival data from ATCA, WSRT, and the VLA, we have analyzed the HI emission of 22 tidal tail regions of the Mullan et al. sample of pairwise interacting galaxies. We have measured the column densities, line-of-sight velocity dispersions, and kinetic energy densities on ~kpc scales. We also constructed a tracer of the line-of-sight velocity gradient over ~10 kpc scales. We compared the distributions of these properties between regions that do and do not contain massive star cluster candidates (M_V < -8.5; ~10^4--10^6 M_(sun) as observed in HST WFPC2 VI data). In agreement with Maybhate et al., we find that a local, ~kpc-scale column density of log N_(HI) = 20.6 cm^(-2) is frequently required for detecting clustered star formation. This HI gas also tends to be turbulent, with line-of-sight velocity dispersions ~10--75 km/s, implying high kinetic energy densities (>46 erg pc^(-2)). Thus, high HI densities and pressures, partly determined by the tail dynamical age and other interaction characteristics, are connected to large-scale cluster formation in tidal tails overall. Lastly, we find that the high mechanical energy densities of the gas are likely not generally due to feedback from star formation. Rather, these properties are more likely to be a cause of star formation than a result.

description: Testing rotor blades of wind turbines is essential to mitigate financial risks caused by serial damages. Present day uniaxial dynamic tests are time consuming and often inaccurate regarding the applied loading. This thesis proposes a faster fatigue test method by loading the two primary directions at the same time. In addition, a more realistic test, compared to uniaxial tests, is accomplished by loading larger areas of the blade cross-sections. To achieve this, an elliptical biaxial dynamic excitation is used. To fulfill the industry requirement for cost effective tests, a relatively simple test setup was developed, still achieving an elliptical dynamic excitation of the rotor blade. Two methods for an accurate determination of the applied loadings for dynamic fatigue tests are described. These calibration tests use easily measured values and simple analysis to achieve accurate test load measurements in a cost-effective way.
Social media and perceived climate change efficacy: A European comparison

description: Climate change perceptions interact with how climate change is portrayed in the news, which is now increasingly accessed via social media platforms. While their effects on climate change awareness have been documented, it is less clear to what extent news consumed via social media platforms influences perceived climate change efficacy, which refers to the belief that one is able to make a difference in the fight against climate change. Our paper investigates the relationship between internet use, news received via social media, and perceived climate change efficacy in Europe, by using multilevel regression that shows the effects on individual, national and regional level. We find that there are modest differences between perceived climate change efficacy within our European sample and that on aggregated, national level Facebook negatively correlates with perceived climate change efficacy. Furthermore, regions with high participation in social media, show lower perceived climate change efficacy. Our multi-level research design thus puts new insights into the spatial manifestation of climate change opinions in the context of a digital geography interested in exploring differences in the effects of digital media uses.

description: The dynamical origin of complex networks, i.e., the underlying principles governing network evolution, is a crucial issue in network study. In this paper, by carrying out analysis to the temporal data of Flickr and Epinions--two typical social media networks, we found that the dynamical pattern in neighborhood, especially the formation of triadic links, plays a dominant role in the evolution of networks. We thus proposed a coevolving dynamical model for such networks, in which the evolution is only driven by the local dynamics--the preferential triadic closure. Numerical experiments verified that the model can reproduce global properties which are qualitatively consistent with the empirical observations.

The Dust Tail of Asteroid (3200) Phaethon

description: We report the discovery of a comet-like tail on asteroid (3200) Phaethon when imaged at optical wavelengths near perihelion. In both 2009 and 2012, the tail appears >=350" (2.5x10^8 m) in length and extends approximately in the projected anti-solar direction. We interpret the tail as being caused by dust particles accelerated by solar radiation pressure. The sudden appearance and the morphology of the tail indicate that the dust particles are small, with an effective radius ~1 micrometer and a combined mass ~3x10^5 kg. These particles are likely products of thermal fracture and/or desiccation cracking under the very high surface temperatures (~1000 K) experienced by Phaethon at perihelion. The existence of the tail confirms earlier inferences about activity in this body based on the detection of anomalous brightening. Phaethon, the presumed source of the Geminid meteoroids, is still active.

description: Understanding large scale magnetic field growth in turbulent plasmas in the magnetohydrodynamic limit is a goal of magnetic dynamo theory. In particular, assessing how well large scale helical field growth and saturation in simulations matches that predicted by existing theories is important for progress. Using numerical simulations of isotropically forced turbulence without large scale shear with the implications, we focus on several aspects of this comparison that have not been previously tested: (1) Leading mean field dynamo theories which break the field into large and small scales predict that large scale helical field growth rates are determined by the difference between kinetic helicity and current helicity with no dependence on the non-helical energy in small scale magnetic fields. Our simulations show that the growth rate of the large scale field from fully helical forcing is indeed unaffected by the presence or absence of small scale magnetic fields amplified in a precursor non-helical dynamo. However, because the precursor non helical dynamo in our simulations produced fields that were strongly sub-equipartition with respect to the kinetic energy, we cannot yet rule out the potential influence of stronger non- helical small scale fields. (2) We have identified two features in our simulations which cannot be explained by the most minimalist versions of two-scale mean field theory: (i) fully helical small scale forcing produces significant non-helical large scale magnetic energy and (ii) the saturation of the large scale field growth is time-delayed with respect to what minimalist theory predicts. We comment on desirable generalizations to the theory in this context and future desired work.

description: Microbial interactions within diverse ecosystems are intricately governed by the dynamic interplay of exopolysaccharides (EPSs) produced by microorganisms. This review delves into the multifaceted roles of EPS in microbial signalling, quorum sensing (QS), and community dynamics, highlighting their significance in orchestrating cooperative behaviours and shaping community structures. EPSs serve as pivotal signalling molecules, influencing chemical communication and promoting intricate interactions among microorganisms. The integration of EPS into QS mechanisms adds an additional layer of complexity, allowing microorganisms to assess population density and synchronise communal responses. Furthermore, EPSs actively contribute to community dynamics by influencing spatial organisation, adhesion, and resistance to environmental stressors. By providing comprehensive knowledge of EPS dynamics, this review offers valuable insights into microbial ecology, serving as a foundational resource for future research. It will benefit the research community by advancing our understanding of microbial ecosystems, with broad applications in biotechnology, environmental science, and beyond.
