Wahlsystem und Parteiensystem in Italien
Creators: name: Pallaver, Günther
Publisher: name: Österreichische Zeitschrift für Politikwissenschaft
Year: 2015

description: 1993 wurde in Italien das Verhältniswahlsystem durch ein kombiniertes Wahlsystem ersetzt. Damit sollte das fragmentierte Parteiensystem beseitigt, die Herausbildung eines bipolaren Parteiensystems eingeleitet sowie die Stabilität der Regierungen und eine Alternanz zwischen Regierung und Opposition garantiert werden. Die Bilanz nach drei Parlamentswahlen scheint positiv zu sein: Eine Alternanz an der Regierung ist erfolgt, die Regierungen sind immer stabiler geworden und die tatsächlichen Akteure des Wettbewerbs sind nicht mehr die Parteien, sondern die Wahlkoalitionen. Dennoch ist der italienische Bipolarismus noch nicht konsolidiert, denn die Reform des Wahlsystems hat ein bipolares Parteiensystem mit jeweils zwei Akteuren hervorgebracht: Koalitionen und Parteien. Die Koalitionen haben die Parteien noch nicht ersetzt, die Parteien können auf die Koalitionen nicht verzichten. Der Bipolarisierung der Wahlkoalitionen steht nach wie vor die Fragmentierung der Parteien gegenüber.

description: A malfunction of the cooling system of high-level liquid waste (HLLW) and the failure of countermeasures may lead to the evaporation to dryness due to the loss of cooling functions (EDLCF) of the HLLW. In the EDLCF, ruthenium (Ru) can be released at a greater fraction to the initial amount than the other elements in HLLW by forming gaseous Ru. It is important to identify the chemical form of the released gaseous Ru to achieve a comprehensive understanding of the events impacting the source term assessment of Ru in this accident, such as particle formation, gas absorption, and deposition on migration pathways. In this study, we observed the ultraviolet/visible spectroscopy of the off-gas generated during the heating of a HLLW simulant. Employing a program that allows for the separation and quantification of known components within the spectrum [ruthenium tetroxide (RuO4), nitrogen dioxide, and nitric acid], we attempted to analyze the composition of gaseous Ru within the generated off-gas. Our findings revealed RuO4 as the main component of the gaseous Ru in the off-gas after comparing the total amount of released Ru and the RuO4 released amount obtained via spectroscopic analysis.
Die Entwicklung kompetitiver Wahlsysteme in Mittel- und Osteuropa: Post-sozialistische Entstehungsbedingungen und fallspezifische Reformkontexte

description: Nach dem demokratischen Systemwechsel von 1989/90 führten die meisten mittel- und osteuropäischen Staaten anlässlich ihrer ersten freien Parlamentswahlen („Gründungswahlen“) nicht nur neue Wahlsysteme ein, sondern reformierten sie auch danach ungewöhnlich häufig. Der folgende Beitrag analysiert diesen institutionellen Entwicklungsprozess systematisch-vergleichend für sechs post-sozialistische Staaten (Russland, Ukraine, Polen, Ungarn, Slowakei und Tschechien). Auf Basis theoretischer Überlegungen zur Reform politischer Institutionen bestätigt sich dabei die These von Nohlen/Kasapovic (1996), dass die Gründungswahlsysteme wesentlich vom Systemwechseltypus geprägt wurden  allerdings nur dort, wo die Entscheidung über das Wahlsystem in die unmittelbare Transitionsphase fiel. Spätere Wahlsystemreformen sind nicht mehr durch den Demokratisierungsmodus, sondern durch kontextspezifische Variablenkonstellationen zu erklären.

description: We investigate the free boundary Schur process, a variant of the Schur process introduced by Okounkov and Reshetikhin, where we allow the first and the last partitions to be arbitrary (instead of empty in the original setting). The pfaffian Schur process, previously studied by several authors, is recovered when just one of the boundary partitions is left free. We compute the correlation functions of the process in all generality via the free fermion formalism, which we extend with the thorough treatment of "free boundary states". For the case of one free boundary, our approach yields a new proof that the process is pfaffian. For the case of two free boundaries, we find that the process is not pfaffian, but a closely related process is. We also study three different applications of the Schur process with one free boundary: fluctuations of symmetrized last passage percolation models, limit shapes and processes for symmetric plane partitions, and for plane overpartitions.

description: For all convex co-compact hyperbolic surfaces, we prove the existence of an essential spectral gap, that is a strip beyond the unitarity axis in which the Selberg zeta function has only finitely many zeroes. We make no assumption on the dimension $δ$ of the limit set, in particular we do not require the pressure condition $δ\leq {1\over 2}$. This is the first result of this kind for quantum Hamiltonians. Our proof follows the strategy developed by Dyatlov-Zahl [arXiv:1504.06589]. The main new ingredient is the fractal uncertainty principle for $δ$-regular sets with $δ<1$, which may be of independent interest.

description: We construct a Schwinger-Keldysh effective field theory for relativistic hydrodynamics for charged matter in a thermal background using a superspace formalism. Superspace allows us to efficiently impose the symmetries of the problem and to obtain a simple expression for the effective action. We show that the theory we obtain is compatible with the Kubo-Martin-Schwinger condition, which in turn implies that Green's functions obey the fluctuation-dissipation theorem. Our approach complements and extends existing formulations found in the literature.

description: A simple and fast analysis method to sort large data sets into groups with shared distinguishing characteristics is described, and applied to single molecular break junction conductance versus electrode displacement data. The method, based on principal component analysis, successfully sorted data sets based on the projection of the data onto the first or second principal component of the correlation matrix without the need to assert any specific hypothesis about the expected features within the data. This was an improvement on the current correlation matrix analysis approach because it sorted data automatically, making it more objective and less time consuming, and our method is applicable to a wide range of multivariate data sets. Here the method was demonstrated on two systems. First, it was demonstrated on mixtures of two molecules with identical anchor groups, similar lengths, but either a $π$ (high conductance) or $σ$ (low conductance) bridge. The mixed data was automatically sorted into two groups containing one molecule or the other. Second, it was demonstrated on break junction data measured with the $π$ bridged molecule alone. Again the method distinguished between two groups. These groups were tentatively assigned to different geometries of the molecule in the junction.

description: In Wahlsystemfragen gibt es keinen Stillstand. Besonders im Zuge der dritten Welle der Demokratisierung hat es viele Wahlsystemwechsel gegeben. Aber auch in einigen gestandenen Demokratien fanden grundlegende Wahlreformen statt. Der Beitrag fragt nach allgemeinen Tendenzen der Wahlsystementwicklung auf der Ebene der Wahlsystemtypen. Er stellt die multidimensionalen Funktionsanforderungen an Wahlsysteme heraus und fragt danach, welche Wahlsystemtypen ihnen am ehesten gerecht werden. Sodann werden die Entwicklungen nach Regionen aufgezeigt. Der beobachtete gewisse Trend zu kombinierten Wahlsystemen wird mit der höheren Funktionsleistung dieser Wahlsysteme erklärt, ohne andere Faktoren, welche die Wahl oder das Design von Wahlsystemen bestimmen, zu vernachlässigen.

Year: 2015

description: Während die westeuropäische „Neue Rechte“ bei ihrem Versuch, die kulturelle Hegemonie im EU-Raum zu erlangen, bisher nur mäßige Erfolge erzielt hat, ist es während des vergangenen Jahrzehnts einer ähnlichen russischen Bewegung unter ihrem intellektuellen Führer Aleksandr Dugin gelungen, mittels „politischer Mimikry“ tief in den Diskurs des politischen und akademischen Mainstreams der Rußländischen Föderation einzudringen. Dabei dient der Begriff „Eurasismus“ als Deckmantel für ein abstruses antiliberales, insbesondere antiamerikanisches Theoriengebäude, welches Grundzüge einer faschistischen Ideologie trägt. Seit dem Ende des vergangenen Jahrhunderts hat es Dugin vermocht, führende Vertreter der russischen Zivilgesellschaft, Massenmedien, Sozialwissenschaften, Politik und Ministerialbürokratie für seine Ideen zu interessieren und an seine Organisation zu binden.

Ultra-high Compton Frequency, Parity Independent, Mesoscopic Schrödinger Cat Atom Interferometer with Heisenberg Limited Sensitivity

description: We present a protocol for an atomic interferometer that reaches the Heisenberg Limit (HL), within a factor of $\sim$ $\sqrt{2}$, via collective state detection and critical tuning of one-axis twist spin squeezing. It generates a Schrödinger cat (SC) state, as a superposition of two extremal collective states. When this SC interferometer is used as a gyroscope, the interference occurs at an ultrahigh Compton frequency, corresponding to a mesoscopic single object with a mass of $Nm$, where $N$ is the number of particles in the ensemble, and $m$ is the mass of each particle. For $^{87}$Rb atoms, with $N=10^{6}$, for example, the intereference would occur at a Compton frequency of $\sim$ $2 \times 10^{31}$ Hz. Under this scheme, the signal is found to depend critically on the parity of $N$. We present two variants of the protocol. Under Protocol A, the fringes are narrowed by a factor of $N$ for one parity, while for the other parity the signal is zero. Under Protocol B, the fringes are narrowed by a factor of $N$ for one parity, and by a factor of $\sqrt{N}$ for the other parity. Both protocols can be modified in a manner that reverses the behavior of the signals for the two parities. Over repeated measurements under which the probability of being even or odd is equal, the averaged sensitivity is smaller than the HL by a factor of $\sim$ $\sqrt{2}$ for both versions of the protocol. We show that when the SC interferometer is configured as an accelerometer, the effective two-photon wave vector is enhanced by a factor of $N$, leading to the same degree of enhancement in sensitivity. We also show that such a mesoscopic single object can be used to increase the effective base frequency of an atomic clock by a factor of $N$, with a sensitivity that is equivalent to the HL, within a factor of $\sim$ $\sqrt{2}$.

Mechanism of the double heterostructure TiO2/ZnO/TiO2 for photocatalytic and photovoltaic applications: A theoretical study

description: Understanding the mechanism of the heterojunction is an important step towards controllable and tunable interfaces for photocatalytic and photovoltaic based devices. To this aim, we propose a thorough study of a double heterostructure system consisting of two semiconductors with large band gap, namely, wurtzite ZnO and anatase TiO2. We demonstrate via first-principle calculations two stable configurations of ZnO/TiO2 interfaces. Our structural analysis provides a key information on the nature of the complex interface and lattice distortions occurring when combining these materials. The study of the electronic properties of the sandwich nanostructure TiO2/ZnO/TiO2 reveals that conduction band arises mainly from Ti3d orbitals, while valence band is maintained by O2p of ZnO, and that the trapped states within the gap region frequent in single heterostructure are substantially reduced in the double interface system. Moreover, our work explains the origin of certain optical transitions observed in the experimental studies. Unexpectedly, as a consequence of different bond distortions, the results on the band alignments show electron accumulation in the left shell of TiO2 rather than the right one. Such behavior provides more choice for the sensitization and functionalization of TiO2 surfaces.

description: Der Beitrag beschäftigt sich mit einem der gewinnbringendsten Zweige der Internetbranche, der Mainstream-Internetpornografie und ihren Rahmenbedingungen im Kontext der Politik der Europäischen Union zu illegalen und schädigenden Internetinhalten. Basierend auf dem Framing-Ansatz wird der Politikprozess zum „Mehrjährigen Aktionsplan zur sichereren Nutzung des Internets“ aus grundrechtlicher und feministischer Perspektive untersucht. Dabei wird das Policy Framing der beteiligten EU-AkteurInnen insbesondere hinsichtlich geschlechtersensibler Herangehensweisen und den ihnen zugrunde liegenden theoretischen Zugängen analysiert. Die dominanten Policy Frames der AkteurInnen werden aus unterschiedlichen Schwerpunkten in der Zielsetzung und Definition illegaler und schädigender Internetinhalte und deren grundrechtlichen Implikationen sowie der strategischen Positionierung der AkteurInnen zwischen „möglichen Grundrechtseingriffen“ oder der „Betonung liberaler Abwehrrechte“ abgeleitet.

Assessing the influence of an institutional Muslim life program on the Muslim student university experience

Publisher: name: No Publisher Supplied
Year: 2024

description: Institutional Muslim life programs at universities in the United States are growing in number and their importance is often highlighted in supporting Muslim university students through avenues like providing a safe space, spiritual education, counseling, and fostering community building with the greater campus. While literature exists on their historical development and presence at universities, minimal research has been conducted on the measured impact that these institutional programs have on Muslim student life experiences. This study aims to fill that void and employs a mixed-methods case study design to examine the influence that one public state university institutional Muslim life program has on the Muslim student experience. Through site observations, a questionnaire, and individual and focus group interviews with students and program administrators, student perceptions of institutional Muslim life and its level of influence were analyzed. With student voices as the main source of data, the findings of this study demonstrate that institutional Muslim life program does in fact influence the Muslim student experience in a variety of ways, including that on a communal, institutional, and personal level. The data showcases that an institutional Muslim life program facilitates for Muslim students to develop greater levels of faith understanding and spirituality and that it also serves as a way to obtain capital. Furthermore, the findings relay that while Muslims in America may be in the midst of a tense and hostile social climate, the primary motivation for most Muslim students to engage with institutional Muslim life programming lies not in countering anti-Muslim sentiment, but in connecting with their faith and spirituality on a personal level. This study provides measured data that Muslim university students do benefit from institutional Muslim life programs and serves as encouragement for educational institutions and administrators to consider supporting and establishing these kinds of institutions within their communities.
Search for supersymmetry in pp collisions at sqrt(s) = 13 TeV in the single-lepton final state using the sum of masses of large-radius jets

description: Results are reported from a search for supersymmetric particles in proton-proton collisions in the final state with a single lepton; multiple jets, including at least one b-tagged jet; and large missing transverse momentum. The search uses a sample of proton-proton collision data at sqrt(s) = 13 TeV recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 35.9 inverse femtobarns. The observed event yields in the signal regions are consistent with those expected from standard model backgrounds. The results are interpreted in the context of simplified models of supersymmetry involving gluino pair production, with gluino decay into either on- or off-mass-shell top squarks. Assuming that the top squarks decay into a top quark plus a stable, weakly interacting neutralino, scenarios with gluino masses up to about 1.9 TeV are excluded at 95% confidence level for neutralino masses up to about 1 TeV.

description: Gemäß einem umfassenden Verständnis bestehen Digital Rights Management-Systeme aus drei interdependenten Komponenten: technologische, rechtliche und wirtschaftliche Bestandteile. Aus ihrer Integration in eine soziale Umgebung resultieren vielfältige Interessenkonflikte, die die Steuerung der DRM-Systeme durch das Recht begleiten. Dieser Artikel untersucht aus policy-analytischer Perspektive eine neue Steuerungsstrategie für DRM-Systeme und damit auch für digitale Inhalte. Die konkreten Interessenkonflikte um den Einsatz von DRM-Systemen werden nicht adressiert, um den Rahmen dieses Artikels nicht zu sprengen. Der Artikel befasst sich jedoch mit den Effekten der vorgestellten Steuerungsstrategie auf politische Entscheidungsfindungsprozesse und der Implementation der Strategie in die politische Realität. Das zentrale Ziel dieses Artikels ist es, dem/der LeserIn einen Überblick über diese neue Form politischer Steuerung von digitalen Inhalten zu geben.

description: Sterilisation of implantable biomaterials such as hydrogels remains a key step towards their clinical translation. Standard sterilisation methods can significantly alter hydrogels’ physicochemical and biological performance. Previously, we developed composite hydrogels based on ε-polylysine (ε-PL) and hyaluronic acid (HA). The developed hydrogels demonstrated promising antibacterial activity and in vitro cell viability and their variable properties depending on the chosen ε-PL to HA ratio. In this study, we fabricated a series of chemically crosslinked ԑ-PL/HA hydrogels with expanded ԑ-PL to HA mass ratios. Using small-angle X-ray scattering (SAXS), we unravelled the topological differences between physically and chemically crosslinked hydrogels. We then selected the chemically crosslinked hydrogel ԑ-PL/HA series of 60:40 wt%, 70:30 wt%, and 80:20 wt% ratios, with similar network topologies, to evaluate the impact of steam sterilisation on their physicochemical and viscoelastic properties. The antibacterial activity of the sterilized hydrogels was also evaluated against Gram-negative and Gram-positive bacteria. Our results showed that steam sterilisation minimally affects structure and physicochemical properties of ԑ-PL/HA hydrogels. Furthermore, the developed hydrogel ԑ-PL/HA series of 60:40 wt%, 70:30 wt%, and 80:20 wt% ratios showed pronounced antibacterial activity against Gram-negative and Gram-positive pathogenic bacteria. We expect our results will contribute to the growing understanding of using sterilisation methods for antibacterial hydrogels that have the potential for wider tissue engineering applications.

description: Die Videoüberwachung des öffentlichen Raums breitet sich in nahezu ganz Europa scheinbar unaufhaltsam weiter aus. Die Kamera wird damit zunehmend zu einem Zeichen sozialen Wandels. Als Technologie, der per se die Fähigkeit zur Erzeugung von Sicherheit zugeschrieben wird, ist sie zu einem Symbol einer überschießenden Nachfrage nach Sicherheit geworden, die sich mit ihrer Hilfe gerade nicht befriedigen lässt. Diese Entwicklung stellt, so die These dieses Beitrages, nicht nur einen weitreichenden Eingriff in die Bürger- und Menschenrechte der Betroffenen dar. Sie beschädigt darüber hinaus die Integrationskraft und damit eine der zentralen Entwicklungs- und Leistungsvoraussetzungen moderner demokratischer Rechtsstaaten.

Gross Hematuria: Recurrent Phosphate Staghorn Calculi in a Healthy Adult - A Case Report
Creators: name: Poole, MS4, Nicole
Publisher: name: BMJHS Case Reports
Year: 2024

description: Abstract:

Staghorn calculi are large renal stones that fill the pelvis of the kidney and pose a significant risk of urosepsis and intrinsic kidney damage. In this case, a 25-year-old healthy female presented with gross hematuria after vigorous cardiovascular exercise for six months. Computed tomography scan demonstrated a 5.4 cm right sided staghorn calculi with hydronephrosis. Right sided percutaneous nephrolithotomy followed by ureteroscopy was performed to remove the stone. On follow up ultrasound 3.5 weeks later, a 16 mm conglomerate of calculi was reformed in the lower calyx, requiring a second ureteroscopy for resolution. Nephrology workup for stone etiology was complicated because the patient did not maintain a stone free period for the gold standard 48 hour urine collection.

The case emphasizes a complete workup of gross hematuria, even in healthy young adults and to acknowledge exercise induced hematuria is a diagnosis of exclusion after complete workup for other causes. It highlights the gap in knowledge on staghorn calculi, likely due to the fewer number of cases per year despite the stone free rates for after staghorn calculi surgery being only 42%. There is need for better analysis as the current standard (48 hour urine collection) requires stone free periods that some patients, such as this one, may not be able to maintain and ultimately delay diagnosis and require more surgical procedures and medical risks.

description: Nach herkömmlicher Auffassung bedeuten die technologischen Entwicklungen des Cyberspace eine besondere Gefahr für die Gewährleistung bürgerlicher Freiheitsrechte. Der indiskrete Blick in und auf das Privatleben der BürgerInnen wird durch neu erschlossene Überwachungsmöglichkeiten im Rahmen eines dafür geeigneten, erweiterten Kommunikationsumfeldes erleichtert. Dabei ist der Blick in die Ideengeschichte für die Beurteilung des genannten Zusammenhangs instruktiv. Es wird hier argumentiert, dass Freiheitsrechte weder unabhängig vom jeweiligen Staatsverständnis noch von den ihnen zugewiesenen “Funktionen” begriffen werden können. Lockes Konzept der “Freiheit in der Gesellschaft” und Jellineks “Freiheit vom Staat” werden exemplarisch einander gegenüber gestellt. Die Nutzung beider Ansätze zur Analyse des genannten Zusammenhangs von Freiheitsrechten und Cyberspace erbringt keinen zwingenden Schluss, dass Freiheitsrechte substantiell einer neuen Gefährdung ausgesetzt werden.

description: STAT5AKO mice (STAT5fl/fl:AdipoQ-Cre/+), which have Stat5a and Stat5b genes flanked by loxP sites (floxed; fl) and express Cre protein under control of the adiponectin (AdipoQ) promoter, and floxed littermate control mice (STAT5fl/fl:+/+) were used in this study. For the duration of the study, mice were fed standard chow (13% kcal from fat), housed at 22 ± 2°C and 45–55% humidity, under a 12-h light/dark cycle, and given free access to food and water. They were randomized into treatment groups according to body weight, body composition and blood glucose. At the end of the treatment period, mice were humanely euthanized by exsanguination via cardiac puncture under isoflurane inhalation followed by cervical dislocation. All regulations of the Institutional Animal Care and Use Committee at Pennington Biomedical Research Center were strictly followed, and experiments were performed under approved protocol 1097.Male and female 9-week old mice were treated with corticosterone (CORT) for one week. CORT was administered in the drinking water at a concentration of 100 ug/mL in 1% ethanol; the vehicle group received 1% ethanol in their drinking water. Water intake was measured during the treatment period, and water was refreshed every three to four days. Body weight and body composition were measured before and after CORT treatment. Excised adipose and liver tissues were fixed in 10% neutral buffered formalin for a minimum of 24 hours. Tissues were processed, embedded in paraffin, stained with hematoxylin and eosin (H and E), and imaged by the Cell Biology and Bioimaging Core at Pennington Biomedical Research Center. Brown adipose tissue (BAT) and inguinal white adipose tissue (iWAT) excised from the mice were also snap frozen in liquid nitrogen and then subjected to RNA purification and reverse transcription (RT)-qPCR analysis. These supplemental figures include body composition data, images of H&E stained iWAT, gWAT, or liver from 3 - 7 male or female mice per group, and gene expression data from BAT and iWAT.

description: Zunehmende politische Apathie und Desinteresse hat auch zu sinkender Wahlbeteiligung geführt. Wahlrechtsreformen versuchen diesen Abwärtstrend zu mildern. Eine neue Wahlinfrastruktur wird insbesondere auf lokaler Ebene getestet, die zum Teil eine Laborfunktion besitzt. Online- Wahlen und andere Formen des Electronic voting sind dabei eher die High-Tech- Varianten. Neben diesen Instrumenten ist die Briefwahl erneut in den Vordergrund gerückt, die in bezug auf die Wahlrechtsgrundsätze wie Geheimhaltung und Gleichheit des Wählervotums ähnliche Probleme aufwirft. In einigen Ländern hat die Briefwahl eine lange Tradition als Alternative zur Präsenzwahl, andere haben erfolgreich universelle Briefwahlen getestet und andere setzen sie gar nicht oder nur auf bestimmte Gruppen begrenzt ein. Die nationalen Regelungen sowie Strategien werden aufgezeigt, wobei in den sechs ausgewählten Ländern einen hohe Pfadabhängigkeit deutlich wird, die auch die zukünftigen Entwicklungen prägen wird.

description: The cosmological Higgs vacuum stability has been an attractive research subject and it is crucial to accurately follow the development of the Higgs fluctuations. In this work, we thoroughly investigate how the vacuum fluctuations of the Higgs field affect the stability of the electroweak vacuum in Friedmann-Lemaitre-Robertson-Walker (FLRW) background. Adopting adiabatic (WKB) approximation or adiabatic regularization methods, we clearly show that vacuum fluctuations of the Higgs field in the FLRW background depend on the curvature and also masses of the Higgs or other scalar fields. The Higgs fluctuations can generate true vacuum bubbles and trigger off a collapse of the electroweak vacuum. Furthermore we clearly show that the effective Higgs potential in the FLRW background is modified by the Higgs vacuum fluctuations. The vacuum fluctuations of the standard model fields can stabilize or destabilize the effective Higgs potential through backreaction effects. Considering the improved effective Higgs potential with the Higgs vacuum fluctuations $\left< { δϕ}^{ 2 } \right>$ in various backgrounds, we provide new cosmological constraints on the mass of the Higgs-coupled scalar fields and a quantitative description of the Higgs stability in the FLRW background.

description: STAT5AKO mice (STAT5fl/fl:AdipoQ-Cre/+), which have Stat5a and Stat5b genes flanked by loxP sites (floxed; fl) and express Cre protein under control of the adiponectin (AdipoQ) promoter, and floxed littermate control mice (STAT5fl/fl:+/+) were used in this study. For the duration of the study, mice were fed standard chow (13% kcal from fat), housed at 22 ± 2°C and 45–55% humidity, under a 12-h light/dark cycle, and given free access to food and water. They were randomized into treatment groups according to body weight, body composition and blood glucose. At the end of the treatment period, mice were humanely euthanized by exsanguination via cardiac puncture under isoflurane inhalation followed by cervical dislocation. All regulations of the Institutional Animal Care and Use Committee at Pennington Biomedical Research Center were strictly followed, and experiments were performed under approved protocol 1097. Male and female 9-week old mice were treated with corticosterone (CORT) for one week. CORT was administered in the drinking water at a concentration of 100 mg/mL in 1% ethanol; the vehicle group received 1% ethanol in their drinking water. Water intake was measured during the treatment period, and water was refreshed every three to four days. Excised adipose and liver tissues were fixed in 10% neutral buffered formalin for a minimum of 24 hours. Tissues were processed, embedded in paraffin, stained with hematoxylin and eosin (H and E), and imaged by the Cell Biology and Bioimaging Core at Pennington Biomedical Research Center. These supplemental figures include images of H&E stained iWAT, gWAT, or liver from 3 - 7 male or female mice per group.

description: In this paper, an approach to predict thermo-mechanically induced changes of sub-surface properties during discontinuous profile gear grinding is presented. The approach faces industrial boundary conditions, such as varying material stock removal as well as the drawback of possible localized thermal damage on the ground tooth flanks. The basic idea is to consider the sub-surface properties after grinding as a function of “tempering time” and temperature due to the short-time heat treatment by the grinding process. Consequently, a time-temperature-diagram showing surface layer modifications for profile gear grinding based on the measurement of local contact zone temperatures has been set up.

description: Nonclassical states of a quantized light are described in terms of Glauber-Sudarshan P distribution which is not a genuine classical probability distribution. Despite several attempts, defining a uniform measure of nonclassicality (NC) for the single mode quantum states of light is yet an open task. In our previous work [Phys. Rev. A 95, 012330 (2017)] we have shown that the existing well-known measures fail to quantify the NC of single mode states that are generated under multiple NC-inducing operations. Recently, Ivan et. al. [Quantum. Inf. Process. 11, 853 (2012)] have defined a measure of non-Gaussian character of quantum optical states in terms of Wehrl entropy. Here, we adopt this concept in the context of single mode NC. In this paper, we propose a new quantification of NC for the single mode quantum states of light as the difference between the total Wehrl entropy of the state and the maximum Wehrl entropy arising due to its classical characteristics. This we achieve by subtracting from its Wehrl entropy, the maximum Wehrl entropy attainable by any classical state that has same randomness as measured in terms of von-Neumann entropy. We obtain analytic expressions of NC for most of the states, in particular, all pure states and Gaussian mixed states. However, the evaluation of NC for the non-Gaussian mixed states is subject to extensive numerical computation that lies beyond the scope of the current work. We show that, along with the states generated under single NC-inducing operations, also for the broader class of states that are generated under multiple NC-inducing operations, our quantification enumerates the NC consistently.

description: We studied the stable magnetic structure of ordered Nd$_{6}$Fe$_{14-x}$Ga$_x$ ($x = 0, 1)$ alloys, which appears in the grain-boundary (GB) phase of Nd-Fe-B permanent magnets, using first-principles techniques. Slight Ga doping ($x = 1$) was shown to contribute to the stabilization of an anti-ferromagnetic (AF) state, whereas the non-doped case ($x = 0$) was revealed to favor ferromagnetic state rather than AF state with a slight energy difference.
Zur Außenwahrnehmung der FPÖ: Der Mediendiskurs in Frankreich, Israel und Schweden über die Nationalratswahlen und die Regierungsbildungen in den Jahren 1999/2000 und 2002/2003

description: Die Erfolge der FPÖ bei den Nationalratswahlen im Jahr 1999 und ihre anschließende Regierungsbeteiligung haben nicht nur in Österreich sondern auch international zu heftigen Reaktionen und Debatten geführt. Ein Element vieler dieser Debatten waren Bewertungen der FPÖ und ihres damaligen Vorsitzenden Jörg Haider sowie Versuche, Erklärungen für die Erfolge derselben zu finden. Der vorliegende Artikel analysiert und vergleicht mit Methoden der Kritischen Diskursanalyse die Mediendiskurse zu diesen Themen in Israel, Frankreich und Schweden. Darüber hinaus wird untersucht, ob bzw. wie sich die Verluste der FPÖ bei den NR-Wahlen im Jahr 2002 auf die Darstellung der FPÖ bzw. von Jörg Haider auswirkten und welche Veränderungen zum Untersuchungszeitraum 1999/2000 feststellbar waren. Einerseits divergieren die Wahrnehmungen über die FPÖ in den jeweiligen Ländern, andererseits lassen sich Gemeinsamkeiten feststellen, wie die Fokussierung der Berichterstattung auf Jörg Haider und Erklärungsversuche seiner Erfolge durch die österreichische Vergangenheitspolitik. Es zeigt sich, dass Unterschiede in den historischen und politischen Narrativen sowie den innenpolitischen Gegebenheiten in den untersuchten Ländern sich in den Diskursen zu Jörg Haider und der FPÖ widerspiegeln.

Existentially self deceptive storytelling: a new genre
Creators: name: Anderson, George
Publisher: name: University of Westminster
Year: 2009

description: This thesis is an exploration into the function and form of storytelling. Its initial assumption is that consciousness is a genetically transmitted mechanism which generates a concept of self by creating a story. In this formulation, the consciousness is called narrative-consciousness. Since the concept of self necessarily suggests its opposite and this in turn involves awareness of existential futility, the purpose of the story, generated by the narrative-consciousness, is seen to be, in the first instance, the hiding of this unavoidable and potentially damaging awareness. This thesis suggests that to achieve this goal the story must be based on the process of self-deception. The thesis shows that, in general, self-deception involves three significant components in its bid to separate any two paradoxical ideas: unease, process and hiding and that each of these maps onto a particular component in the final narrative of the self. The narrative created by a consciousness hiding, in particular, the awareness of existential angst is given the specific name existentially-self deceptive- story, with an acronym ESDeS. The thesis goes on to suggest that such a narrative-consciousness could produce written stories that follow the same pattern, in which case the stories are called existentially-self-deceptive-novels, with an acronym ESDeN. Such a story or genre is then shown to be part of a continuum consisting of up to three distinct ways of dealing with existential futility. The thesis labels these Story-1, Story-2 and Story-3 respectively but reserves the name ESDeN for a subset of Story-2. Analyses of three of these stories, Heart of Darkness, Chance and Thinks concludes that the genre necessarily includes genre-markers, bracketing deaths and repetition, can also include other optional components such as the self-deceptive process or the parent-child mechanism but that its defining characteristic is its division between an overt plot and a covert plot which contains a collusive death of a character identified with existential angst. A covert plot is necessarily available but it is, by definition, not easily discovered. Its successful hiding is made possible, primarily, by foregrounding the overt content of the novel at the expense of the covert. In this sense, the only necessary requirement of the overt content is it should distract and it does this best when the reader cooperates by investing time in interpretation: that is, in order to disguise the ultimate the reader concentrates on the proximal. Finally, the thesis mirrors the endings of each ESDeN by drawing attention to the fact that this collusion will not work for long: just as self-deception cannot withstand too much contrary evidence, the covert plot will not stand too many rereadings. Inevitably, for the true ESDeS, another point of recognition will occur and this will necessitate the renewal or replacement of the ESDeS.
