description: Hyperhidrosis (excessive sweating) is associated with significant quality-of-life burden yet is often undertreated. With limited FDA-approved treatments, health care providers must determine optimal treatment among approved and off-label options. Key objectives of this review were to reassess, update, and expand a previous systematic review of commonly used treatment options for primary hyperhidrosis, including consideration of aluminum and zirconium compounds. We performed a qualitative systematic review of efficacy, health-related quality of life, satisfaction, and safety of interventions, replicating and expanding the strategy outlined in a previous systematic review, with the addition of studies utilizing a within-patient design. We performed a critical appraisal of identified studies to determine risk of bias (RoB) and strength of evidence (SOE). A total of 32 studies were eligible for critical appraisal. Only three studies – two clinical trials of glycopyrronium cloth (2.4%) and one trial of botulinum toxin A injections in axillary hyperhidrosis were rated as “low” RoB; both had SOE ratings of “moderate” for use in axillary hyperhidrosis – the highest rating included in this review. Optimal treatment choice depends on several factors, including understanding the quality of evidence regarding each treatment’s efficacy and safety (considerations of convenience and cost are beyond the scope of this review). In hyperhidrosis, as in other clinical conditions, treatment decisions should be patient centered. At this time, because of the quality of evidence, only imprecise estimates of effect are possible for hyperhidrosis treatments included in this review, and statements about comparative effectiveness are not possible.

description: The GLAST Burst Monitor (GBM) will augment the capabilities of GLAST for the detection of cosmic gamma-ray bursts by extending the energy range (20 MeV to > 300 GeV) of the Large Area Telescope (LAT) towards lower energies by 2 BGO-detectors (150 keV to 30 MeV) and 12 NaI(Tl) detectors (10 keV to 1 MeV). The physical detector response of the GBM instrument for GRBs is determined with the help of Monte Carlo simulations, which are supported and verified by on-ground calibration measurements, performed extensively with the individual detectors at the MPE in 2005. All flight and spare detectors were irradiated with calibrated radioactive sources in the laboratory (from 14 keV to 4.43 MeV). The energy/channel-relations, the dependences of energy resolution and effective areas on the energy and the angular responses were measured. Due to the low number of emission lines of radioactive sources below 100 keV, calibration measurements in the energy range from 10 keV to 60 keV were performed with the X-ray radiometry working group of the Physikalisch-Technische Bundesanstalt (PTB) at the BESSY synchrotron radiation facility, Berlin.

description: Industrielle Hochtemperatursynthesen, die mit reinem Sauerstoff als Oxidator, betrieben werden unterscheiden sich signifikant von konventioneller Verbrennung (Luft als Oxidator). In dieser Arbeit wird die Entwicklung einer modularen Versuchsanlage im Labormaßstab vorgestellt, die die Untersuchungen des Einflusses einzelner Parameter (Äquivalenzverhältnis, Vorwärmtemperatur und Druck) auf die Flammenstruktur von brennstoffreichen CH4/O2-Flammen ermöglicht. Die gewählten Randbedingungen sind an industrielle Prozesse angelehnt. Zur experimentellen Untersuchung der laminar vorgemischten flachen Flammen wurden sowohl optische als auch invasive Messtechniken eingesetzt. Mittels Laser-basierter absorptionsspektroskopischer Untersuchungen (TDLAS) des H2O-Moleküls konnten sowohl Temperatur- als auch Konzentrationsprofile direkt ermittelt werden. Mittels invasiver Probenentnahme in Kombination mit einem Gaschromatographen und Massenspektrometer (GC/MS) konnten die Edukte und weitere Hauptprodukte der Verbrennung experimentell gemessen werden. In umfangreichen Voruntersuchungen wurden neben der Identifikation geeigneter Absorptionslinien auch eine Software zur Steuerung und Auswertung der TDLAS-Messungen entwickelt und eine geeignete Sondengeometrie zur invasiven Probenentnahme bestimmt. Ein Vergleich der experimentellen Ergebnisse mit den Ergebnissen detaillier-ter Reaktionsmechanismen zeigte, dass selbst bei den Hauptprodukten der Verbrennung große Unterschiede zwischen den Messergebnissen und einzelnen Mechanismen liegen. Es zeigte sich, dass je nach betrachteter Spezies unterschiedliche Reaktionsmechanismen mit den experimentellen Ergebnissen übereinstimmen. Dies hebt die Bedeutung der Erfassung experimenteller Daten für die Entwicklung oder Erweiterung detaillierter Reakti-onsmechanismen für die Anwendung in brennstoffreichen Oxy-Fuel Flammen hervor. Des Weiteren wurden bei der Ermittlung von Temperaturen und H2O-Konzentrationen jeweils Maximalwerte gemessen, die deutlich über den Gleichgewichtsbedingungen liegen. Dies ist auf das Phänomen der super-adiabaten Flammentemperaturen (SAFT) zurückzuführen, das für brennstoff-reiche Kohlenwasserstoff/Oxidator-Flammen charakteristisch ist und durch die unterschiedlichen chemischen Zeitmaße der schnellen exothermen Oxidationsreaktionen und endothermen Synthesegasproduktion erklärt werden kann. Erstmals konnte der Einfluss der Parameter Äquivalenzverhältnis, Vorwärmtemperatur und Druck auf SAFT in brennstoffreichen CH4/O2-Flammen experimentell ermittelt werden.

description: This work presents a novel approach for semi-supervised semantic segmentation. The key element of this approach is our contrastive learning module that enforces the segmentation network to yield similar pixel-level feature representations for same-class samples across the whole dataset. To achieve this, we maintain a memory bank continuously updated with relevant and high-quality feature vectors from labeled data. In an end-to-end training, the features from both labeled and unlabeled data are optimized to be similar to same-class samples from the memory bank. Our approach outperforms the current state-of-the-art for semi-supervised semantic segmentation and semi-supervised domain adaptation on well-known public benchmarks, with larger improvements on the most challenging scenarios, i.e., less available labeled data. https://github.com/Shathe/SemiSeg-Contrastive

description: Receptor activator of NF-κβ ligand (RANKL) is crucial for the development of hepatic insulin resistance and poor glucose uptake; therefore, inhibiting RANKL with Denosumab could improve fasting plasma glucose (FPG) and insulin (FPI). A systematic review was conducted to evaluate the effects of Denosumab on glycemic parameters. PubMed, SCOPUS, EBSCO, and LILACS databases were searched for studies that investigated the effect of Denosumab on FPG, glycated hemoglobin (HbA1c), FPI, and Homeostatic Model Assessment for Insulin Resistance (HOMA1-IR). The pooled standard difference in means (SDM) and 95% confidence intervals (95%CI) were calculated. The results were stratified into (1) Normal Glucose Tolerance (NGT) and (2) Impaired Glucose Tolerance (IGT). Six publications (1203 participants) were included. There was a significant association between Denosumab and FPG (SDM = −0.388, 95%CI: −0.705 to −0.070, p = .017) and with HOMA1-IR (SDM = −0.223, 95%CI: −0.388 to −0.058, p = .008), but not for HbA1c and FPI. When stratified by glucose tolerance, the association between Denosumab and FPG, HbA1c, and HOMA1-IR was present for the IGT group. Lastly, Denosumab had a time-dependent effect on HbA1c (slope = −0.037, 95%CI: −0.059 to −0.015, p Denosumab significantly improved glycemic parameters. This outcome was more prominent for subjects with compromised glucose tolerance, positing that Denosumab can be used as a treatment to improve glucose metabolism for persons with pre-diabetes and diabetes.

description: This thesis investigates four different aspects of information security management: challenges faced by security practitioners, interactive collaborations among security practitioners and other stakeholders, diagnostic work performed by security practitioners during the response to incidents, and factors that impact the adoption of an intrusion detection system in one organization. Our approach is based on qualitative analyzes of empirical data from semi-structured interviews and participatory observation. For each theme under study, the contributions of the qualitative analysis are twofold. First, we provide a richer understanding of the main factors that affect the security within organizations. Second, equipped with this richer understanding, we provide recommendations on how to improve security tools, along with opportunities for future research. Our findings contribute to the understanding of the human, organizational, and technological factors that affect security in organizations and the effectiveness of security tools. Our work also highlights the need for continued refinement of how factors interplay by obtaining more rich data (e.g., contextual inquiry), and the need to generalize and validate these findings through other sources of information to study how these factors interplay (e.g., surveys).

description: Assigning the variations of internal energy into heat or work contributions is a challenging task due to the fact that these properties are trajectory dependent. A number of proposals have been put forward for open quantum systems following an arbitrary dynamics. We here focus on non-equilibrium thermodynamics of a two-level system and explore, in addition to the conventional approach, two definitions motivated by either classical work or heat, in which the driving Hamiltonian or the trajectory itself are respectively used to set up a reference basis. We first give the thermodynamic properties for an arbitrary dynamics and illustrate the results on the Bloch sphere. Then, we solve the particular example of a periodically driven qubit interacting with a dissipative and decoherence bath. Our results illustrate the trajectory-dependent character of heat and work, and how contributions originally assigned to dissipation in the Lindblad equation can become coherent part assigned to work.

description: Cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) is a treatment for post-transplant lymphoproliferative disease (PTLD) following solid organ transplant (SOT) after failing rituximab, an aggressive and potentially fatal lymphoma. This study explores the humanistic and economic burden of CHOP-associated adverse events (AEs) in PTLD patients. Since PTLD is rare, searches included lymphoproliferative disease with lymphoma patients. This comprehensive literature review used the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) protocol, pre-specifying the search strategy and criteria. CHOP-associated short-term AEs with an incidence of >4% were sourced from published literature and cancer websites to inform the search strategy. PubMed and EMBASE searches were used to identify humanistic and economic burden studies. PubMed and EMBASE searches identified 3946 citations with 27 lymphoma studies included. Studies were methodologically heterogeneous. Febrile neutropenia (FN) was the AE most encountered, followed by chemotherapy-induced (CI) anemia (A), infection, CI-nausea and vomiting, thrombocytopenia, and CI-peripheral neuropathy (PN). FN and infections were associated with significant disutility, increased hospitalization, and extended length of stay (LOS). Infections and CIPN significantly impacted the utility of patients and CIA-related fatigue showed reductions in quality of life (QoL). Many patients continue to have QoL deficits continued even after AEs were treated. Management costs varied greatly, ranging from nominal (CIPN) to over $100,000 in the USA for infections, EUR 10,290 in Europe for infections, or CAN$1012 in Canada for FN. Cost of outpatient care varied but had a lower economic impact compared to hospitalizations. Short-term AEs from CHOP in the lymphoma population were associated with substantial humanistic and economic burden.

description: We have studied the spacetime of a Kerr black hole immersed in Melvin magnetic field, and found not only unstable light rings could exist, but also stable light rings could exist. Both the prograde and retrograde unstable light rings radiuses increase with the magnetic field parameter $B$, but it is the opposite for stable light rings. The existence of unstable, stable light rings depend on both the rotation parameter $a$ and the magnetic field parameter $B$. For a certain $a$, there are both the prograde and retroprade unstable (stable) light rings when $B$ is less than a critical value $B_{c}$ of retrograde light ring. In this case, the shadows of Melvin-Kerr black hole have two gray regions on both sides of the middle main shadow, which correspond to the prograde and retrograde stable photon orbits. The photons in stable orbits are always moving around Melvin-Kerr black hole, they can't enter the black hole or escape to infinity. As $B$ continues to increase, there is only the prograde unstable (stable) light ring. In this case, the gray region only emerges in the life of the main shadow, which corresponds to the prograde stable photon orbits. The absence of the retrograde unstable (stable) light rings makes the Melvin-Kerr black hole shadow an half-panoramic (equatorial) shadow. When $B$ is bigger than $B_{C}$ of prograde light ring, neither prograde nor retroprade unstable (stable) light rings exist. In this case, the shadow of Melvin-Kerr black hole has no gray region for stable photon orbits, and becomes a panoramic (equatorial) shadow. In addition, there also exist some self-similar fractal structures in the shadow of Melvin-Kerr black hole arising from the chaotic motion of photon.

description: A destabilization in the transfer energy flux from the vacuum to radiation, for two vacuum decay laws relevant to the dark energy problem, is analyzed using the Landau-Lifshitz fluctuation hydrodynamic theory. Assuming thermal (or near thermal) equilibrium between the vacuum and radiation, at the earliest epoch of the Universe expansion, we show that the law due to renormalization-group running of the cosmological constant term, with parameters chosen not to spoil the primordial nucleosynthesis scenario, does soon drive the flux to fluctuate beyond its statistical average value thereby distorting the cosmic background radiation spectrum beyond observational limits. While the law coming from the saturated holographic dark energy does not lead the flux to wildly fluctuate, a more realistic non--saturated form shows again such anomalous behavior.

description: We study analytical properties of the hard exclusive processes amplitudes. We found that QCD factorization for deeply virtual Compton scattering and hard exclusive vector meson production results in the subtracted dispersion relation with the subtraction constant determined by the Polyakov-Weiss $D$-term. The relation of this constant to the fixed pole contribution found by Brodsky, Close and Gunion and defined by parton distributions is proved, while its manifestation is spoiled by the small $x$ divergence. The continuation to the real photons limit is considered and the numerical correspondence between lattice simulations of $D$-term and low energy Thomson amplitude is found.

description: We investigate distortions in the velocity fields of disc galaxies and their use to reveal the dynamical state of interacting galaxies at different redshift. For that purpose, we model disc galaxies in combined N-body/hydrodynamic simulations. 2D velocity fields of the gas are extracted from these simulations which we place at different redshifts from z=0 to z=1 to investigate resolution effects on the properties of the velocity field. To quantify the structure of the velocity field we also perform a kinemetry analysis. If the galaxy is undisturbed we find that the rotation curve extracted from the 2D field agrees well with long-slit rotation curves. This is not true for interacting systems, as the kinematic axis is not well defined and does in general not coincide with the photometric axis of the system. For large (Milky way type) galaxies we find that distortions are still visible at intermediate redshifts but partly smeared out. Thus a careful analysis of the velocity field is necessary before using it for a Tully-Fisher study. For small galaxies (disc scale length ~2 kpc) even strong distortions are not visible in the velocity field at z~0.5 with currently available angular resolution. Therefore we conclude that current distant Tully-Fisher studies cannot give reliable results for low-mass systems. Additionally to these studies we confirm the power of near-infrared integral field spectrometers in combination with adaptive optics (such as SINFONI) to study velocity fields of galaxies at high redshift (z~2).

description: We consider how causality and micro-causality are realised in QED in curved spacetime. The photon propagator is found to exhibit novel non-analytic behaviour due to vacuum polarization, which invalidates the Kramers-Kronig dispersion relation and calls into question the validity of micro-causality in curved spacetime. This non-analyticity is ultimately related to the generic focusing nature of congruences of geodesics in curved spacetime, as implied by the null energy condition, and the existence of conjugate points. These results arise from a calculation of the complete non-perturbative frequency dependence of the vacuum polarization tensor in QED, using novel world-line path integral methods together with the Penrose plane-wave limit of spacetime in the neighbourhood of a null geodesic. The refractive index of curved spacetime is shown to exhibit superluminal phase velocities, dispersion, absorption (due to γ\to e^+e^-) and bi-refringence, but we demonstrate that the wavefront velocity (the high-frequency limit of the phase velocity) is indeed c, thereby guaranteeing that causality itself is respected.

description: After the work of Gladman et al. (1998), it is now assessed that many irregular satellites are orbiting around Uranus. Despite many studies have been performed in past years, very few is know for the light-curves of these objects and inconsistencies are present between colours derived by different authors. This situation motivated our effort to improve both the knowledge of colours and light curves. We present and discuss time series observations of Sycorax, Prospero, Stephano, Setebos and Trinculo, five faint irregular satellites of Uranus, carried out at VLT, ESO Paranal (Chile) in the nights between 29 and 30 July, 2005 and 25 and 30 November, 2005. We derive light curves for Sycorax and Prospero and colours for all of these these bodies. For Sycorax we obtain colours B-V =0.839 +/- 0.014, V-R = 0.531 +/- 0.005 and a light curve which is suggestive of a periodical variation with period about 3.6 hours and amplitude about 0.067 +/- 0.004 mag. The periods and colours we derive for Sycorax are in agreement with our previous determination in 1999 using NTT. We derive also a light-curve for Prospero which suggests an amplitude of about 0.2 mag and a periodicity of about 4 hours. However, the sparseness of our data, prevents a more precise characterization of the light-curves, and we can not determine wether they are one-peaked or two-peaked. Hence, these periods and amplitudes have to be considered preliminary estimates. As for Setebos, Stephano and Trinculo the present data do not allow to derive any unambiguous periodicity, despite Setebos displays a significant variability with amplitude about as large as that of Prospero. Colours for Prospero, Setebos, Stephano and Trinculo are in marginal agreement with the literature.

description: Kagome superconductors with Tc up to 7K have been discovered over 40 years. Recently, unconventional chiral charge order has been reported in kagome superconductor KV3Sb5, with an ordering temperature of one order of magnitude higher than the TC. However, the chirality of the charge order has not been reported in the cousin kagome superconductor CsV3Sb5, and the electronic nature of the chirality remains elusive. In this letter, we report the observation of electronic chiral charge order in CsV3Sb5 via scanning tunneling microscopy (STM). We observe a 2x2 charge modulation and a 1x4 superlattice in both topographic data and tunneling spectroscopy. 2x2 charge modulation is highly anticipated as a charge order by fundamental kagome lattice models at van Hove filling, and is shown to exhibit intrinsic chirality. We find that the 1x4 superlattices forms various small domain walls, and can be a surface effect as supported by our first-principles calculations. Crucially, we find that the amplitude of the energy gap opened by the charge order exhibits real space modulations, and features 2x2 wave vectors with chirality, highlighting the electronic nature of the chiral charge order. STM study at 0.4K reveals a superconducting energy gap with a gap size 2Δ=0.85meV, which estimates a moderate superconductivity coupling strength with 2Δ/kBTc=3.9. When further applying a c-axis magnetic field, vortex core bound states are observed within this gap, indicative of clean-limit superconductivity.

description: Man könnte Lisa Sinan eine fahrende Künstlerin nennen. Ihre Werke bestehen aus unterschiedlichen Materialien, Stoffen, Farben und Dingen, die sie in ihrem Auto transportiert und erst vor Ort zu großen Installationen verbindet. Dieses methodische Vorgehen gleicht einem ungeplanten Umzug in ein Museumszimmer, in dem Sinan site specific wieder und wieder auf die Architekturen reagieren muss – ohne das Atelier als sichere Probebühne. Ihre Arbeiten zeichnet ein sicheres Empfinden für Farben und Form aus. Mit genauer Beobachtungsgabe spielt sie in vermeintlicher Simplizität mit den Grenzen bildhauerischer Fiktion. Durch additive Verfahren wird der vorhandene Raum in Türme und Burggräben verwandelt, heimlich verdoppelt sich eine Säule, farblich wird die Ausgangsarchitektur akzentuiert und kommentiert. In anderen Werken versteckt Sinan Reales, unter der brauen Zeltplane oder hinter dem Sichtschutz des Setzkastens. In einer Installation aus 2018 folgen wir ihr auf den Balkon mit Geländer um schließlich festzustellen, dass unser Ausblick durch den weißen Leinwandstoff verhindert wird. Neben der klugen und prägnanten Formensprache weisen ihre Arbeiten auch einen hohen persönlichen Anteil auf. Die Titel, verwendete Sounds oder kleine Details geben einen Einblick in einen ganz eigenen Humor, mit dem die Künstlerin Räume erschafft, in denen sie selbst viele Stunden lang während des Aufbaus gelebt und gearbeitet hat. Das verwendete Material stammt aus dem eigenen Fundus, bestimmte Motive wie das Geländer kehren immer wieder. Biografische Beziehungen schimmern durch diese Arbeiten und geben ihnen neben aller Experimentalität eine Zugänglichkeit ohne ins Bekenntnishafte abzurutschen: Lisa Sinans Kunst ist lebendig, aber nicht privat. von Svenja Reiner

description: This work summarizes our research on the topic of the creation and evaluation of security tools against SQL injection attacks (SQLIAs). We introduce  briefly the key concepts and problems of information security and we present  the ma jor role that SQL Injection is playing in this scenario. Based on the  above analysis and on today's computer security state-of-the-art, we focus  our research on the specific field of SQLIAs, which are still one of the most  exploited and dangerous intrusion techniques used to access web applications.  More exactly we address both the problems of (1) how to completely evaluate  SQLIAs security systems in order to achieve useful results and subsequently  a better level of security by proposing a novel evaluation methodology, and  (2) how to be safe from SQLIAs by creating and presenting, as a case study  of our evaluation procedure, an effective tool for detecting and preventing  known as wel l as new SQL injection attacks.  The proposal evaluation methodology is general and adaptable to any security tools for detection or prevention of SQLIAs. It is a complete step-by-step  procedure which provides a guideline to test and value important characteristics such as efficiency, effectiveness, stability, flexibility and performance and  achieves usable and comparable results to properly judge the tested tool. In  addiction, as a case study of our methodology, we present the evaluation of  our tool we have named SQLPrevent which dynamically detects SQL injection attacks using a heuristics approach, and blocks the corresponding SQL  statements from being submitted to the back-end database. In our experiments, SQLPrevent produced no false positives or false negatives, it has  100% detection and prevention rate measured on different types of SQLIAs,  is environment independence, and imposed on average of 0.3% performance  overhead.

description: Windows Vista's personal firewall provides its diverse users with a basic interface that hides many operational details. However, our study of this interface revealed that concealing the impact of network context on the security state of the firewall results in mental models that are unclear about the protection provided by the firewall resulting in an inaccurate understanding of the firewall configuration. We developed a prototype to support more contextually complete mental models through inclusion of network context information. Results from our initial evaluation of the prototype support our approach of improving user understanding of underlying system states by revealing hidden context, while considering the tension between complexity of the interface and security of the system.

description: We present results from a study of 94 red giant stars in the globular cluster M53. We use low-resolution spectra to measure the strength of CN and CH features at $\sim$3800 and 4300 Å, respectively. The strengths of these features are used to classify stars into a CN-enhanced and CN-normal population and to measure C and N abundances in all 94 stars. We find the red giant branch stars to be evenly split between the two populations identified, and observe the presence of CN-enhanced stars on the asymptotic giant branch. In addition, we identify 5 CH star candidates based on the strength of their CN and CH band features, and the presence of a P-branch in their CH band. We compare our identification of multiple populations to those based on the Na-O anti-correlation and pseudo-color indices in HST UV photometry, and find general agreement between all three methods. Our large sample size also allows us to study the radial distribution of each population, and we find that the CN-enhanced population is more centrally concentrated. We use our C and N measurements to compare the evolutionary changes in these elements as a function of magnitude between the two populations, and show that both populations experience similar evolutionary changes to the surface abundances of C and N. Finally, we calculate C+N+O abundances for each population and compare them to similar measurements made in M10; we find that in both clusters CN-enhanced stars have a slightly enhanced C+N+O ($Δ$(C+N+O) $\sim$ 0.2 dex).

description: Five $Ξ^- p\to ΛΛ$ two-body capture events in $^{12}$C and $^{14}$N emulsion nuclei, in which a pair of single-$Λ$ hypernuclei is formed and identified by their weak decay, have been observed in $(K^-,K^+)$ emulsion exposures at KEK and J-PARC. Applying a $Ξ^-$-nucleus optical potential methodology to study atomic and nuclear transitions, we confirm that these capture events occur from Coulomb assisted $1p_{Ξ^-}$ nuclear states. Long-range $ΞN$ shell-model correlations are found essential to achieve consistency between the $^{12}$C and $^{14}$N events. The resulting $Ξ$-nuclear interaction is strongly attractive, with $Ξ$ potential depth in nuclear matter $V_Ξ\gtrsim 20$ MeV. Implications to multi-strangeness features of dense matter are outlined.

Year: 2021

description: We study the role of driving in an initial maximally entangled state evolving under the presence of a structured environment in a weak and strong regime. We focus on the enhancement and degradation of maximal Concurrence when the system is driven on and out of resonance for a general evolution, as well as the effect of adding a transverse coupling among the particles of the model. We further investigate the role of driving in the acquisition of a geometric phase for the maximally entangled state. As the model studied herein can be used to model experimental situations such as hybrid quantum classical systems feasible with current technologies, this knowledge can aid the search for physical setups that best retain quantum properties under dissipative dynamics.

Generalized Einstein-Maxwell theory: Seeley-DeWitt coefficients and logarithmic corrections to the entropy of extremal and non-extremal black holes

description: We present a consolidated manual of Euclidean gravity approaches for finding the logarithmic corrections to the entropy of the full Kerr-Newman family of black holes in both extremal and non-extremal limits. Seeley-DeWitt coefficients for the quadratic fluctuations of a concern gravity theory appear to be the key ingredients in this manual. Following the manual, we calculate the first three Seeley-DeWitt coefficients and logarithmic corrections to the entropy of extremal and non-extremal black holes in a generalized Einstein-Maxwell theory minimally-coupled to additional massless scalar, vector, spin-1/2 Dirac and spin-3/2 Rarita-Schwinger fields. We finally employ the Seeley-DeWitt data to reproduce the logarithmic entropy corrections for extremal black holes in all $\mathcal{N} \geq 2$ Einstein-Maxwell supergravity via an alternative local supersymmetrization method.

The Refractive Index of Curved Spacetime: the Fate of Causality in QED

description: It has been known for a long time that vacuum polarization in QED leads to a superluminal low-frequency phase velocity for light propagating in curved spacetime. Assuming the validity of the Kramers-Kronig dispersion relation, this would imply a superluminal wavefront velocity and the violation of causality. Here, we calculate for the first time the full frequency dependence of the refractive index using world-line sigma model techniques together with the Penrose plane wave limit of spacetime in the neighbourhood of a null geodesic. We find that the high-frequency limit of the phase velocity (i.e. the wavefront velocity) is always equal to c and causality is assured. However, the Kramers-Kronig dispersion relation is violated due to a non-analyticity of the refractive index in the upper-half complex plane, whose origin may be traced to the generic focusing property of null geodesic congruences and the existence of conjugate points. This puts into question the issue of micro-causality, i.e. the vanishing of commutators of field operators at spacelike separated points, in local quantum field theory in curved spacetime.

description: We consider gauge theories with scalar matter with and without supersymmetry at nonzero chemical potential. It is argued that a chemical potential plays a role similar to the FI term. We analyze theory at weak coupling regime at large chemical potential and argue that it supports nonabelian non-BPS strings. Worldsheet theory on the nonabelian string in a dense matter is briefly discussed.

description: Long Gamma Ray Bursts hold the promise of probing star-formation and metal enrichment up to very high redshifts. The present GRB samples with redshift determination are largely incomplete and therefore a careful analysis of selection effects is mandatory before any conclusion can be drawn from the observed GRB redshift distribution. We study and compare three well defined samples of long GRBs detected by Swift, HETE2 and BeppoSAX. We find that Swift GRBs are slighly fainter and harder than BeppoSAX and HETE2 GRBs, as expected due to the higher energy range in which Swift GRBs are detected and localized, compared to BeppoSAX and HETE2. Gas and dust obscuration plays a role in shaping the GRB samples and the present samples of GRBs with redshift. We argue that the majority of the bright Swift GRBs without redshift might actually be z

description: When a low flux of time-frequency-entangled photon pairs (EPP) illuminates a two-photon transition, the rate of two-photon absorption (TPA) can be enhanced considerably by the quantum nature of photon number correlations and frequency correlations. We present a quantum-theoretic derivation of entangled TPA (ETPA) and calculate an upper bound on the amount of quantum enhancement that is possible in such systems. The derived bounds indicate that in order to observe ETPA the experiments would need to operate at a combination of significantly higher rates of EPP illumination, molecular concentrations, and conventional TPA cross sections than are achieved in typical experiments.
