description: We describe the current status and the prospect for the development of monolithic Ge:Ga array detector for SAFARI. Our goal is to develop a 64x64 array for the 45 -- 110 um band, on the basis of existing technologies to make 3x20 monolithic arrays for the AKARI satellite. For the AKARI detector we have achieved a responsivity of 10 A/W and a read-out noise limited NEP (noise equivalent power) of 10^-17 W/rHz. We plan to develop the detector for SAFARI with technical improvements; significantly reduced read-out noise with newly developed cold read-out electronics, mitigated spectral fringes as well as optical cross-talks with a multi-layer antireflection coat. Since most of the elemental technologies to fabricate the detector are flight-proven, high technical readiness levels (TRLs) should be achieved for fabricating the detector with the above mentioned technical demonstrations. We demonstrate some of these elemental technologies showing results of measurements for test coatings and prototype arrays.

Asymptotic Independence of the Extreme Eigenvalues of GUE

description: We give a short, operator-theoretic proof of the asymptotic independence (including a first correction term) of the minimal and maximal eigenvalue of the n \times n Gaussian Unitary Ensemble in the large matrix limit n \to \infty. This is done by representing the joint probability distribution of the extreme eigenvalues as the Fredholm determinant of an operator matrix that asymptotically becomes diagonal. As a corollary we obtain that the correlation of the extreme eigenvalues asymptotically behaves like n^{-2/3}/4σ^2, where σ^2 denotes the variance of the Tracy--Widom distribution. While we conjecture that the extreme eigenvalues are asymptotically independent for Wigner random hermitian matrix ensembles in general, the actual constant in the asymptotic behavior of the correlation turns out to be specific and can thus be used to distinguish the Gaussian Unitary Ensemble statistically from other Wigner ensembles.

description: In the framework of 't Hooft's quantization proposal, we show how to obtain from the composite system of two classical Bateman's oscillators a quantum isotonic oscillator. In a specific range of parameters, such a system can be interpreted as a particle in an effective magnetic field, interacting through a spin-orbit interaction term. In the limit of a large separation from the interaction region one can describe the system in terms of two irreducible elementary subsystems which correspond to two independent quantum harmonic oscillators.

description: Aims: We reanalyse optical spectra of the z=6.7 gamma-ray burst GRB 080913, adding hitherto unpublished spectra, in order to reassess the measurement of the neutral fraction of the IGM at high redshifts. Methods: In the data reduction we take particular care to minimise systematic errors in the sky subtraction, which are evident in the published spectrum, and compromise the analysis. The final combined spectrum has a higher S/N than the previously published spectrum by a factor of 1.3. Results: We find a single significant absorption line redward of the Ly-alpha continuum break, which we identify with the SII+SiII blend (rest wavelength of 0.1260 micron), at z=6.733. The sharp spectral break at Ly-alpha implies a comparatively low total column density of neutral hydrogen along the line of sight, log [N(HI)/cm^-2] < 20. We model the absorption with a host-galaxy DLA, surrounded by an ionised region of unknown size r, within the IGM of neutral fraction, x(HI). Despite knowing the source redshift, and the improved S/N of the spectrum, when fitting only over wavelengths redward of Ly-alpha, no useful constraints on x(HI) can be obtained. We consider the possibility of including the ionised region, blueward of Ly-alpha, in constraining the fit. For the optimistic assumption that the ionised region is transparent, tau_{GP} << 1, we find that the region is of small size r < 2 proper Mpc, and we obtain an upper limit to the neutral fraction of the IGM at z=6.7 of x(HI) < 0.73.

Decaying Dark Matter can explain the electron/positron excesses

description: PAMELA and ATIC recently reported excesses in e+ e- cosmic rays. Since the interpretation in terms of DM annihilations was found to be not easily compatible with constraints from photon observations, we consider the DM decay hypothesis and find that it can explain the e+ e- excesses compatibly with all constraints, and can be tested by dedicated HESS observations of the Galactic Ridge. ATIC data indicate a DM mass of about 2 TeV: this mass naturally implies the observed DM abundance relative to ordinary matter if DM is a quasi-stable composite particle with a baryon-like matter asymmetry. Technicolor naturally yields these type of candidates.

Electrical properties of evaporated silicon films
Creators: name: Tucker, Trevor William
Publisher: name: University of British Columbia
Year: 2011

description: The Hall coefficient and conductivity of silicon films vacuum deposited on 0° and 60° sapphire at 850°C to 1050°C were measured from 100°K to 550°K. Films made from 0.094 Ω-cm p type and 1 Ω-cm n type silicon sources were prepared by electron bombardment heating of the source in a vacuum of 5 x 10⁻⁷ to 10⁻⁶ torr. The orientation and crystallinity of the films were investigated using electron diffraction. It was found that defects in the films introduced both donor and acceptor levels. The heavy compensation thus produced in films deposited at lower temperatures lead to a very low hole concentration. All films were p type at room temperature showing that the acceptor levels slightly dominated the donor levels. The films deposited on 0° sapphire indicated fewer defects than those deposited on 60° sapphire. At high temperature (> 950°C) doping of the silicon by aluminum atoms from the substrate was appreciable. The Hall mobility of the films made from the p type source material decreased with increasing temperature of deposition. This apparent anomaly is explained by the use of the polycrystalline film model suggested by Volger (1950).

description: A new family of decagonal quasiperiodic tilings are constructed by the use of generalized point substitution processes, which is a new substitution formalism developed by the author [N. Fujita, Acta Cryst. A 65, 342 (2009)]. These tilings are composed of three prototiles: an acute rhombus, a regular pentagon and a barrel shaped hexagon. In the perpendicular space, these tilings have windows with fractal boundaries, and the windows are analytically derived as the fixed sets of the conjugate maps associated with the relevant substitution rules. It is shown that the family contains an infinite number of local isomorphism classes which can be grouped into several symmetry classes (e.g., $C_{10}$, $D_5$, etc.). The member tilings are transformed into one another through collective simpleton flips, which are associated with the reorganization in the window boundaries.

75As NMR study of single crystals of the heavily overdoped pnictide superconductors Ba{1-x}KxFe2As2 (x = 0.7 and 1)

description: We performed $^{75}$As NMR studies on two overdoped high-quality Ba$_{1-x}$K$_{x}$Fe$_2$As$_2$ (x=0.7 and 1.0) single crystals. In the normal states, we found a dramatic increase of the spin-lattice relaxation ($1/^{75}T_1$) from the x=0.7 to the x=1.0 samples. In KFe$_2$As$_2$, the ratio of $1/^{75}T_1TK_n^2$, where $^{75}K_n$ is the Knight shift, increases as temperature drops. These results indicate the existence of a new type of spin fluctuations in KFe$_2$As$_2$ which is accustomed to being treated as a simple Fermi liquid. In the superconducting state, we observe a step-like feature in the temperature dependence of the spin-lattice relaxation of the x=0.7 sample, which supports a two-gap superconductivity as the underdoped materials. However, the temperature scalings of $1/^{75}T_1$ below Tc in the overdoped samples are significantly different from those in the under or optimal doped ones. A power-law scaling behavior $1/^{75}T_1T\sim T^{0.5}$ is observed, which indicates universal strong low energy excitations in the overdoped hole-type superconductors.

description: We explore different evolutionary scenarios to explain the helium deficiency observed in H1504+65, the most massive known PG1159 star. We concentrate mainly on the possibility that this star could be the result of mass loss shortly after the born-again and during the subsequent evolution through the [WCL] stage. This possibility is sustained by recent observational evidence of extensive mass-loss events in Sakurai's object and is in line with the recent finding that such mass losses give rise to PG1159 models with thin helium-rich envelopes and large rates of period change, as demanded by the pulsating star PG1159-035. We compute the post born again evolution of massive sequences by taking into account different mass-loss rate histories. Our results show that stationary winds during the post-born-again evolution fail to remove completely the helium-rich envelope so as to explain the helium deficiency observed in H1504+65. Stationary winds during the Sakurai and [WCL] stages only remove at most half of the envelope surviving the violent hydrogen burning during the born-again phase. In view of our results, the recently suggested evolutionary connection born-again stars --> H1504+65 --> white dwarfs with carbon-rich atmospheres is difficult to sustain unless the whole helium-rich envelope could be ejected by non-stationary mass-loss episodes during the Sakurai stage.

Subjects: International criminal law

description: The thesis topic centres around the rules of evidence and procedure in international criminal trails. Specifically the dissertation examines the manner in which the common law and civil law trial models have influenced the development of international criminal proceedings, and the impact this has had upon the imperative to meet with the international standard of a fair trial. The thesis illustrates this point by evaluating the procedural and evidentiary tensions that arose in the trial of Prosecutor v José Cardoso Fereira (known as the Lolotoe trial) as a case study. This trial was heard before the Special Panel for Serious Crimes, East Timor, in which I appeared as sole defence counsel.

description: Dear Editor,
We would like to comment on “Tuberculosis of the Cervix Mimicking Cervical Carcinoma: A Case Report [1].”The authors of
this case report detail a rare instance of cervix tuberculosis in a 31-year-old nulliparous woman who presented with symptoms
similar to those of invasive cervical cancer. The patient continued to experience irregular vaginal discharge and intermenstrual
bleeding even after receiving previous treatments for cervical cancer. A biopsy confirmed the diagnosis of tuberculosis after a
friable erythematous lesion on the ectocervix was discovered during examination. The illness was effectively managed with
anti-tuberculosis drug treatment.

Wie digitalisiert war der Bundestagswahlkampf 2021? Zwölf Thesen
Creators: name: Vowe, Gerhard
Publisher: name: Zeitschrift für Parteienwissenschaften
Year: 2021

description: Die Digitalisierung des Wahlkampfs hat viele Facetten, von denen zwölf im Beitrag erörtert werden. Die Pandemie zwang zunächst alle an der Wahl Beteiligten in die Digitalität und löste damit steile Lernkurven aus, prägte aber wenig die Schlussphase des Wahlkampfs. Entscheidende Bedeutung für den Wahlkampf hatte die Skandalisierung des Lachens von Laschet in Erftstadt. Sie war aber nur möglich, weil in diesem Bild die Vorstellungen der Wähler und der Journalisten von Laschet kristallisierten. Insgesamt gewannen die digitalen Medien in der Wähleransprache und in der Anhängermobilisierung weiter an Raum. Insbesondere Microtargeting mittels sozialer Netzmedien ist zur Routine geworden. Für das Wahlergebnis einzelner Parteien waren digitale Medien in unterschiedlicher Richtung von großer Bedeutung. So konnte die AfD ihr Stammwählerpotenzial halten, weil sie an den etablierten Medien vorbei intensiv digital kommunizierte. Und die SPD konnte auch deshalb zulegen, weil sich in der Partei eine Selbstverpflichtung zur digitalen Zurückhaltung durchsetzte. Und nicht zuletzt: Die Legitimität der Wahl war entgegen vieler Befürchtungen auch nicht im Ansatz durch digitale Instrumente gefährdet.

Are black holes big enough to quench cooling in cluster cool cores?

description: Total energy arguments (e.g., Fabian et al. 2002) suggest that black holes need to have masses significantly in excess of the prediction from the classic black hole mass - velocity dispersion relation (M-sigma) in order to offset the cooling losses in massive cool core clusters. This suggests that the black holes may be too small to power such clusters. However, Lauer et al. (2007) argue that the black hole mass - bulge luminosity relationship is a better predictor of black hole masses in high luminosity galaxies and that this relationship predicts significantly higher masses in BCGs. They find slow increase in the velocity dispersion with luminosity and a more rapid increase in effective radii with luminosity seen in BCGs as opposed to less luminous galaxies. Motivated by these results and the theoretical work of Boylan-Kolchin et al. (2006) on isolated mergers, we perform high-resolution cosmological simulations of dry mergers in a massive galaxy cluster identified in the Millennium Run including both the dark matter halos and stellar bulges of merging galaxies. We demonstrate that the BCG clearly evolves away from the size-luminosity relation as defined by the smaller galaxies (i.e., the relation bends) and we also see a bending in the luminosity-sigma relation. As black hole mass is expected to be proportional to the mass and luminosity of the stellar bulge of the BCGs (if they were formed in predominantly dissipationless mergers), our findings are consistent with those of Lauer et al. (2007) on a qualitative level and suggest that the black holes in BCGs may indeed be more massive than predicted from the standard M-sigma relation.

description: Background: Patients living with HIV infection remain at increased risk of cardiovascular diseases and sudden cardiac death. Various prevalence of electrocardiographic (ECG) abnormalities among HIV-infected patients were reported: Attamah et al reported the prevalence of electrocardiographic abnormalities among HIV-infected patients as 34.5%, while Orunta et al reported a prevalence of 42.9%, and Njoku et al reported a prevalence of 93.0%. Human immunodeficiency virus-infected patients are at increased risk of developing prolonged QT interval. Sani et al reported the prevalence of prolonged corrected QT interval among HIV-infected patients as 45.0%. Innocent et al reported a prevalence of48.0%, while Ajala et al reported a prevalence of 18%. Prolonged QTc interval increases the risk of premature ventricular contraction which can degenerate into ventricular tachycardia and or ventricular that can result in sudden cardiac death.

Methodology: The study was a cross-sectional conducted among HIV-infected patients receiving HAART at the Federal Medical Centre Nguru, Yobe State, North Eastern Nigeria.

Results: One hundred and seven (107) subjects were recruited into the study comprising thirty-three (37.0%) males and 70(65.4%) females. The mean CD4 cell count, and viral load of the studied patients were 612.64±34.75 cells/μL and 4646.30±58.68 copies/mL respectively. Twenty (18.7%) patients had prolonged QTc interval, this gave us the prevalence of prolonged QTc in this study as 18.7%. The commonest cardiac rhythm was sinus rhythm (69.2%), followed by sinus tachycardia (26.2%) and atrial fibrillation 5(4.7%). Other electrocardiographic findings include First-degree atrioventricular block was seen in seven (6.5%) patients, Premature ventricular contractions were found in16.8%, RBBB was observed in 2.8%, 3.7% of patients had LBBB and 4.7% had left posterior hemiblock. The distribution of QTc interval according to CD4 cells count and viral revealed a statistically significant difference across the groups. All the patients with prolonged QTc interval had lower CD4 cells count and higher viral load suggesting that HIV disease severity is associated with prolonged QTc interval.

Conclusion: In conclusion, the study revealed that the prevalence of prolonged QTc interval among HIV infected patients on highly active antiretroviral therapy was found to be 18.7%, and that HIV disease severity increases the risk of developing prolonged QTc interval.

description: Bündnis 90/Die Grünen verzeichnen seit 2018 zweistellige jährliche Wachstumsraten hinsichtlich ihrer Mitgliedszahlen. Der vorliegende Beitrag analysiert die geografische Verteilung dieses Mitgliederwachstums auf der Ebene der Landkreise beziehungsweise der kreisfreien Städte. Dabei wird zwischen Veränderungen in der Parteimitgliederdichte und absolutem und relativem Wachstum unterschieden. Im Anschluss an einen deskriptiven Überblick über die geografische Verteilung, werden mögliche Einflussfaktoren auf die Ausprägung des regionalen Mitgliederwachstums getestet. Unsere Daten zeigen, dass die Grünen in allen Regionen Deutschlands wachsen. Das Ausmaß des Wachstums der regionalen Parteigliederung wird dabei mit Ausnahme des relativen Wachstums durch einen zunehmenden Grad der Ländlichkeit negativ beeinflusst. Gleichzeitig wachsen grüne Kreisverbände auch in ländlichen Gebieten deutlich, wenn deren sozio-ökonomische Lage überdurchschnittlich gut ist.

Cosmological measurements, time and observables in (2+1)-dimensional gravity

description: We investigate the relation between measurements and the physical observables for vacuum spacetimes with compact spatial surfaces in (2+1)-gravity with vanishing cosmological constant. By considering an observer who emits lightrays that return to him at a later time, we obtain explicit expressions for several measurable quantities as functions on the physical phase space of the theory: the eigentime elapsed between the emission of a lightray and its return to the observer, the angles between the directions into which the light has to be emitted to return to the observer and the relative frequencies of the lightrays at their emission and return. This provides a framework in which conceptual questions about time, observables and measurements can be addressed. We analyse the properties of these measurements and their geometrical interpretation and show how they allow an observer to determine the values of the Wilson loop observables that parametrise the physical phase space of (2+1)-gravity. We discuss the role of time in the theory and demonstrate that the specification of an observer with respect to the spacetime's geometry amounts to a gauge fixing procedure yielding Dirac observables.

New Approaches To Photometric Redshift Prediction Via Gaussian Process Regression In The Sloan Digital Sky Survey

Publisher: name: arXiv

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: Expanding upon the work of Way and Srivastava 2006 we demonstrate how the use of training sets of comparable size continue to make Gaussian process regression (GPR) a competitive approach to that of neural networks and other least-squares fitting methods. This is possible via new large size matrix inversion techniques developed for Gaussian processes (GPs) that do not require that the kernel matrix be sparse. This development, combined with a neural-network kernel function appears to give superior results for this problem. Our best fit results for the Sloan Digital Sky Survey (SDSS) Main Galaxy Sample using u,g,r,i,z filters gives an rms error of 0.0201 while our results for the same filters in the luminous red galaxy sample yield 0.0220. We also demonstrate that there appears to be a minimum number of training-set galaxies needed to obtain the optimal fit when using our GPR rank-reduction methods. We find that morphological information included with many photometric surveys appears, for the most part, to make the photometric redshift evaluation slightly worse rather than better. This would indicate that most morphological information simply adds noise from the GP point of view in the data used herein. In addition, we show that cross-match catalog results involving combinations of the Two Micron All Sky Survey, SDSS, and Galaxy Evolution Explorer have to be evaluated in the context of the resulting cross-match magnitude and redshift distribution. Otherwise one may be misled into overly optimistic conclusions.

description: Background: Methicillin-Resistant Staphylococcus aureus (MRSA) is both a human commensal and a pathogen that causes neonatal infection which is associated with significant morbidity and mortality. Its genetic flexibility and versatility have equipped it with the ability to develop resistance to numerous antibiotics. Outbreaks of infections in neonatal intensive care units as well as community infections have been reported mostly in developed countries. However, there is a paucity of data on neonatal MRSA infection in developing countries. The study aims to highlight cases of MRSA infection, describe the clinical presentation, and outline the antibiotic susceptibility pattern among term neonates in our facility.

Methodology: It was a prospective cross-sectional hospital-based study carried out from October 2018 to July 2019. A total of 248 term neonates with suspected sepsis were enrolled in the study and had their blood samples taken for investigations including blood culture. Bacterial identification and antibiotic susceptibility patterns were carried out using MicrobactTM24E (Oxiod UK) and Staph ID and modified Kirby-Bauer disk diffusion technique respectively.

Results: Out of the 248 subjects enrolled in the study, 34.2% had proven sepsis, with Staphylococcus species accounting for 56.4% of these cases. Among those with staphylococcal sepsis, 56.3% were found to have MRSA infection. Notably, the majority (94.4%) of cases originated from outside the hospital, presenting as neonatal sepsis with non-specific clinical features. Sensitivity testing revealed that ciprofloxacin and chloramphenicol were the most effective antibiotics against the identified pathogens.

Conclusion: The presence of MRSA infections in neonates poses a critical public health threat. This trend underscores the emergence of antimicrobial resistance, potentially compromising treatment efficacy and jeopardizing neonatal well-being. Urgent and decisive measures are necessary to curb this trajectory.

Desinformation und Wahlkampf

description: Sprachliche Entgleisungen sind im Wahlkampf nicht ungewöhnlich. In den letzten Jahren allerdings haben sich die digitalen Wahlkampagnen durch Unsinnsbehauptungen und Lügenverbreitung verschärft und den politischen Diskurs so tief verändert. Der heute dafür geläufige Begriff Fake News beschreibt dieses Phänomen. Eine Folge der Globalisierung ist, dass der Kampf gegen Falschinformationen in Netzwerken auch auf dem Gebiet der nationalen Wahlkampagnen nur auf internationaler Ebene effektiv geführt werden kann. Das ist sicher eine Herausforderung, aber es wäre ein Signal gegen die Staaten, die zu solchen Regelverstößen ermuntern und den demokratischen Willensbildungsprozess gefährden, der – par excellence – Ausdruck der Souveränität ist.
