description: Optical clocks are superior to all other clocks, reaching 1e-18 in their uncertainty. This makes them not only attractive for the field of fundamental research, like testing General Relativity or examining the variance of fundamental constants, but marks them also as potential candidates for the new definition of the second. An essential step towards that direction is the possibility to carry out comparisons of optical clocks at remote sites to have consistency checks of clocks constructed mostly independently by different groups. Satellite-based techniques offer the possibility of simultaneous comparisons over a large variety of baselines. Their instability, however, has been demonstrated to be in the low 1e-15 range at 1 d averaging time for most measurements. In case of two-way satellite time and frequency transfer (TWSTFT), the instability is limited by the modulation bandwidth of the signal. For this work, the full bandwidth of 20 Mchip/s of the commonly used TWSTFT equipment, a SATRE modem, is employed, providing a potential improvement of a factor of 20 with respect to the currently performed TWSTFT measurements for the time scale comparisons contributing to TAI. This technique is used in this work to compare five optical clocks and six microwave fountain clocks located at four different European metrology institutes simultaneously over a period of 26 d. In order to prepare this measurement, extensive studies on the SATRE modem are carried out and presented, and other aspects that need to be taken into account for TWSTFT measurements with low instabilities are discussed, such as atmospheric delays, geometric and relativistic effects and laboratory and roof station setups. The link instability of TWSTFT during the measurement campaign is presented, and compared to the instability of GPS Precise Point Positioning, that is implemented as an additional, independent comparisons technique for the campaign. Relative frequency differences of the optical and the fountain clocks are calculated. For that, a processing was introduced that combines phase and frequency data of different noise types and gaps. A respective estimator for the statistical uncertainty, based on the correlation on the data, is established. The results of both satellite-based techniques show good agreement with each other, and also clocks based on the same frequency transition agree within a 1-σ-uncertainty. The overall uncertainties obtained for TWSTFT are between 2.7e-16 and 3.5e-16 for the optical clock comparisons. Limitations for the uncertainties of the measurements are discussed in detail, the available satellite-based techniques are evaluated with respect to their advantages and drawbacks for similar measurements in the future.

description: Dryland ecosystems commonly exhibit periodic bands of vegetation, thought to form due to competition between individual plants for heterogeneously distributed water. In this paper, we develop a Fourier method for locally identifying the pattern wavenumber and orientation, and apply it to aerial images from a region of vegetation patterning near Fort Stockton, Texas. We find that the local pattern wavelength and orientation are typically coherent, but exhibit both rapid and gradual variation driven by changes in hillslope gradient and orientation, the potential for water accumulation, or soil type. Endogenous pattern dynamics, when simulated for spatially homogeneous topographic and vegetation conditions, predict pattern properties that are much less variable than the orientation and wavelength observed in natural systems. Our local pattern analysis, combined with ancillary datasets describing soil and topographic variation, highlights a largely unexplored correlation between soil depth, pattern coherence, vegetation cover and pattern wavelength. It also, surprisingly, suggests that downslope accumulation of water may play a role in changing vegetation pattern properties.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Effects of an external magnetic field on the fluctuations of quark number, fluctuations and correlations of conserved charges, including baryon number, electric charge and strangeness, are studied in the 2+1 flavor Polyakov--Nambu--Jona-Lasinio model. We find that magnetic field increases fluctuations and correlations in the regime of chiral crossover. It makes the transition of quadratic fluctuations more abrupt, and the peak structure of quartic fluctuations more pronounced. Our calculations indicate that $χ_{4}^{B}/χ_{2}^{B}$, $χ_{4}^{Q}/χ_{2}^{Q}$, and $χ_{11}^{BQ}$ are very sensitive to the external magnetic field and maybe can be used for probes for the strong magnetic field produced in the early stage of noncentral collisions.

description: We present detailed calculations for the Casimir force between a plane and a nanostructured surface at finite temperature in the framework of the scattering theory. We then study numerically the effect of finite temperature as a function of the grating parameters and the separation distance. We also infer non-trivial geometrical effects on the Casimir interaction via a comparison with the proximity force approximation. Finally, we compare our calculations with data from experiments performed with nanostructured surfaces.

The spin-dependent double-differential cross sections and the contributions from the three-body photodisintegration to the ^3He GDH integrand are presented and compared with state-of-the-art three-body calculations at the incident photon energies of 12.8 and 14.7 MeV. The data reveal the importance of including the Coulomb interaction between protons in three-body calculations.

description: The standard model of cosmology is dominated - at the present epoch - by dark energy. Its voids are rigid and Newtonian within a relativistic background. The model prevents them from becoming hyperbolic. Observations of rapid velocity flows out of voids are normally interpreted within the standard model that is rigid in comoving coordinates, instead of allowing the voids' density parameter to drop below critical and their curvature to become negative. Isn't it time to advance beyond nineteenth century physics and relegate dark energy back to the "no significant evidence" box?

description: We report the discovery of an X-ray counterpart of the unidentified very high energy gamma-ray source HESS J1427-608. In the sky field coincident with HESS J1427-608, an extended source was found in the 2-8 keV band, and was designated as Suzaku J1427-6051. Its X-ray radial profile has an extension of sigma=0.9' +/- 0.1' if approximated by a Gaussian. The spectrum was well fitted by an absorbed power-law with N_H=(1.1 +/- 0.3) times 10^23 cm^-2, Gamma=3.1 +0.6/-0.5, and the unabsorbed flux F_X=(9 +4/-2) times 10^-13 erg s^-1 cm^-2 in the 2-10 keV band. Using XMM-Newton archive data, we found seven point sources in the Suzaku source region. However, because their total flux and absorbing column densities are more than an order of magnitude lower than those of Suzaku J1427-6051, we consider that they are unrelated to the Suzaku source. Thus, Suzaku J1427-6051 is considered to be a truly diffuse source and an X-ray counterpart of HESS J1427-608. The possible nature of HESS J1427-608 is discussed based on the observational properties.

description: Banach spaces without the Radon-Nikodým property are characterized as spaces containing bilipschitz images of thick families of geodesics defined as follows. A family $T$ of geodesics joining points $u$ and $v$ in a metric space is called {\it thick} if there is $α>0$ such that for every $g\in T$ and for any finite collection of points $r_1,...,r_n$ in the image of $g$, there is another $uv$-geodesic $\widetilde g\in T$ satisfying the conditions: $\widetilde g$ also passes through $r_1,...,r_n$, and, possibly, has some more common points with $g$. On the other hand, there is a finite collection of common points of $g$ and $\widetilde g$ which contains $r_1,...,r_n$ and is such that the sum of maximal deviations of the geodesics between these common points is at least $α$.

Bounded-size rules: The barely subcritical regime

description: Bounded-size rules are dynamic random graph processes which incorporate limited choice along with randomness in the evolution of the system. One starts with the empty graph and at each stage two edges are chosen uniformly at random. One of the two edges is then placed into the system according to a decision rule based on the sizes of the components containing the four vertices. For bounded-size rules, all components of size greater than some fixed $K\geq 1$ are accorded the same treatment. Writing $\BS(t)$ for the state of the system with nt/2 edges, Spencer and Wormald proved that for such rules, there exists a critical time t_c such that when t< t_c the size of the largest component is of order $\log{n}$ while for $t> t_c$, the size of the largest component is of order $n$. In this work we obtain upper bounds (that hold with high probability) of order $n^{2γ} \log ^4 n$, on the size of the largest component, at time instants $t_n = t_c-n^{-γ}$, where $γ\in (0,1/4)$. This result for the barely subcritical regime forms a key ingredient in the study undertaken in \cite{amc-2012}, of the asymptotic dynamic behavior of the process describing the vector of component sizes and associated complexity of the components for such random graph models in the critical scaling window. The proof uses a coupling of BSR processes with a certain family of inhomogeneous random graphs with vertices in the type space $\Rbold_+\times \cD([0,\infty):\NNN_0)$ where $\cD([0,\infty):\NNN_0)$ is the Skorohod $D$-space of functions that are right continuous and have left limits equipped with the usual Skorohod topology. The coupling construction also gives an alternative characterization (than the usual explosion time of the susceptibility function) of the critical time $t_c$ for the emergence of the giant component in terms of the operator norm of integral operators on certain $L^2$ spaces.

description: Die ersten Cystobactamide wurden 2014 am Helmholtz-Institut für Pharmazeutische Forschung im Saarland (HIPS) durch Fermentation aus dem Myxobakterium Cystobacter sp. Cbv34 isoliert. Sie bestehen aus zwei nicht proteinogenen polyaromatischen Segmenten mit einem einzigartigen Set von para-Aminobenzoesäure-Monomeren und einer ungewöhnlichen beta-Methoxyasparagin-Einheit als Linker. Die Cystobactamide verfügen über eine außerordentlich hemmende Wirkung gegen zahlreiche klinisch relevante Gram-negative Bakterien, indem sie die Topoisomerase IIa adressieren. Die Kombination aus einzigartigen Strukturelementen und breitem antibakteriellem Wirkungsspektrum machen die Cystobactamide zu einer potentiellen Leitstruktur für die Entwicklung einer neuen Klasse von Gyraseinhibitoren. Im Rahmen dieser Arbeit wurden synthetische Zugänge zu den Cystobactamiden etabliert und für große Labormaßstäbe optimiert. Als Leitstruktur diente dabei das Cystobactamid 861-2. Die Schutzgruppenstrategie und die Optimierung der Peptidkupplungen spielte dabei eine herausragende Rolle. Des Weiteren wurden 15 Strukturanaloga synthetisiert, die zur Untersuchung des Struktur-Aktivitäts-Profils verwendet wurden. Da sowohl die Naturstoffe als auch die ersten vereinfachten Derivate eine gewisse Basenlabilität aufwiesen, wurde bei der Wahl der zu synthetisierenden Derivate auf basenstabilere Strukturmotive gesetzt. Darüber hinaus bestimmten die Erkenntnisse der Struktur-Aktivitäts-Beziehungen der 1. Generation die Auswahl der Strukturmotive beim Entwurf einer zweiten Generation synthetischer Analoga. Das Ersetzen einer Amidbindung durch ein Harnstoffmotiv oder das Kürzen von polyaromatischen Segmenten führte zu einem Verlust der biologischen Aktivität. Der Einbau einer hydrolytisch stabilen Triazolgruppe bewahrte die Aktivität gegenüber einigen klinisch relevanten Pathogenen, darunter zum Beispiel P. aeruginosa, S. aureus und A. baumanii. Des Weiteren konnte das Aktivitätsspektrum teils auf K. pneumoniae erweitert werden. Die neuen Analoga werden zur Weiterentwicklung der Verbindungsklasse verwendet, z.B. indem hydrolytisch stabile Einheiten die Halbwertszeit des Arzneimittels erhöhen.

description: Recent advancements in Large Language Models (LLMs) have been reshaping Natural Language Processing (NLP) task in several domains. Their use in the field of Human Resources (HR) has still room for expansions and could be beneficial for several time consuming tasks. Examples such as time-off submissions, medical claims filing, and access requests are noteworthy, but they are by no means the sole instances. However, the aforementioned developments must grapple with the pivotal challenge of constructing a high-quality training dataset. On one hand, most conversation datasets are solving problems for customers not employees. On the other hand, gathering conversations with HR could raise privacy concerns. To solve it, we introduce HR-Multiwoz, a fully-labeled dataset of 550 conversations spanning 10 HR domains to evaluate LLM Agent. Our work has the following contributions: (1) It is the first labeled open-sourced conversation dataset in the HR domain for NLP research. (2) It provides a detailed recipe for the data generation procedure along with data analysis and human evaluations. The data generation pipeline is transferable and can be easily adapted for labeled conversation data generation in other domains. (3) The proposed data-collection pipeline is mostly based on LLMs with minimal human involvement for annotation, which is time and cost-efficient.

description: As is well known, black hole entropy is proportional to the area of the horizon suggesting a holographic principle wherein all degrees of freedom contributing to the entropy reside on the surface. In this note, we point out that large scale dark energy (such as a cosmological constant) constraining cosmic structures can imply a similar situation for the entropy of a hierarchy of such objects.

description: We present a method to estimate the lensing potential from massive galaxy clusters for given observational X-ray data. The concepts developed and applied in this work can easily be combined with other techniques to infer the lensing potential, e.g. weak gravitational lensing or galaxy kinematics, to obtain an overall best fit model for the lensing potential. After elaborating on the physical details and assumptions the method is based on, we explain how the numerical algorithm itself is implemented with a Richardson-Lucy algorithm as a central part. Our reconstruction method is tested on simulated galaxy clusters with a spherically symmetric NFW density profile filled with gas in hydrostatic equilibrium. We describe in detail how these simulated observational data sets are created and how they need to be fed into our algorithm. We test the robustness of the algorithm against small parameter changes and estimate the quality of the reconstructed lensing potentials. As it turns out we achieve a very high degree of accuracy in reconstructing the lensing potential. The statistical errors remain below 2.0% whereas the systematical error does not exceed 1.0%.

Imbalanced Beamforming by a Multi-antenna Source for Secure Utilization of an Untrusted Relay
Creators: name: Mukherjee, Amitav

Year: 2013
Subjects: subject: Information Theory (cs.IT)

description: We investigate a relay network where a multiantenna source can potentially utilize an unauthenticated (untrusted) relay to augment its direct transmission of a confidential message to the destination. Since the relay is untrusted, it is desirable to protect the confidential data from it while simultaneously making use of it to increase the reliability of the transmission. We present a low-complexity scheme denoted as imbalanced beamforming based on linear beamforming and constellation mapping that ensures perfect physical-layer security even while utilizing the untrusted relay. Furthermore, the security of the scheme holds even if the relay adopts the conventional decodeand- forward protocol, unlike prior work. Simulation results show that the proposed imbalanced signaling maintains a constant BER of 0.5 at the eavesdropper at any SNR and number of source antennas, while maintaining or improving the detection performance of the destination compared to not utilizing the relay or existing security methods.

description: Electric dipole moments constitute a competitive method to search for new physics, being particularly sensitive to new CP-violating phases. Given the experimental and theoretical progress in this field and more generally in particle physics, the necessity for more reliable bounds than the ones usually employed emerges. We therefore propose an improved extraction of the electric dipole moment of the electron and the relevant coefficient of the electron-nucleon coupling, taking into account theoretical uncertainties and possible cancellations, to be used in model-dependent analyses. Specifically, we obtain at 95% C.L. |d_e|<=0.14 10^{-26}e cm with present data, which is very similar to the bound typically quoted from the YbF molecule, but obtained in a more conservative manner. We examine furthermore in detail the prospects for improvements and derive upper limits for the dipole moments of several paramagnetic systems presently under investigation, i.e. Cesium, Rubidium and Francium.

description: Flüchtlingsfrauen als sprachlich Handelnde sowie die Wechselwirksamkeit zwischen ihrem biographischen Gepäck und der Alltagsbewältigung stehen im Mittelpunkt dieser interdisziplinär angelegten, qualitativen Studie. Das Hauptanliegen gilt den Fragen nach dem Umgang Fluchtmigrierter mit der Umgebungssprache Deutsch und den mitgebrachten Sprachen und danach, welche Aspekte ihres Lebens vor der Flucht und nach der Ankunft die Zweitsprachenaneignung beeinflussen und bedingen. Entfaltet wird die Arbeit in sieben Papers entlang ausgewählter Schwerpunkte wie Mehrsprachigkeit, Deutschkurse, Ehrenamt von Flüchtlingsfrauen und Erinnerungsorte, wobei die Vorannahmen der Forschung durchgehend kritisch erörtert werden. Zu diesem Zweck wird eine als Flüchtlingscommunity anzusehende Gruppierung als Datengrundlage für die Reflexionen gewählt, und zwar die durch den Bürgerkrieg verursachte Fluchtmigration aus dem südasiatischen Inselstaat Sri Lanka. Die der Familiensprache Tamil mächtigen Flüchtlingsfrauen halten sich über einen längeren Zeitraum ab den 1980er-Jahren hierzulande auf und verfügen folglich über eine breite Palette an Sprach-, Lebens- und Alltagserfahrung in Deutschland. Hierbei fokussiert sich die Studie vorwiegend auf Frauen, die als Erwachsene die Flucht ergriffen haben. Als Hintergrundwissen wird die Studie von den Erfahrungen im Kindes- und Jugendalter Geflüchteter flankiert, um dieser Frage in ihrer Komplexität gerecht zu werden. Interdisziplinär ist die Studie insofern, als sie beabsichtigt, die Erkenntnisse der soziologiegeprägten Geschlechterforschung, insbesondere die der Intersektionalität, für die Untersuchung im Bereich des Deutschen als Fremd- und Zweitsprache fruchtbar zu machen.

Liquid Hole-Multipliers: A potential concept for large single-phase noble-liquid TPCs of rare events
Creators: name: Breskin, Amos
Publisher: name: arXiv
Year: 2013
Subjects: subject: Instrumentation and Detectors (physics.ins-det)
subject: FOS: Physical sciences

description: A novel concept is proposed for large-volume single-phase noble-liquid TPC detectors for rare events. Both radiation-induced scintillation-light and ionization-charge are detected by Liquid Hole-Multipliers, LHM, immersed in the noble liquid. The latter may consist of cascaded Gas Electron Multipliers (GEM), Thick Gas Electron Multiplier (THGEM) electrodes or others, coated with CsI UV-photocathodes. Electrons, photo-induced on CsI by primary scintillation in the noble liquid, and event-correlated drifting ionization electrons are amplified in the cascaded elements primarily through electroluminescence, and possibly through additional moderate avalanche, occurring within the holes. The resulting charge-signals or light-pulses are recorded on anode pads or with photosensors, e.g. gaseous photomultipliers (GPM), respectively. Potential affordable solutions are proposed for multi-ton dark-matter detectors; open questions are formulated for validating this dream.

description: We obtain the the long-wavelength polar optical vibrational modes of semiconductor core-shell nanowires by means of a phenomenological continuum model. A basis for the space of solutions is derived, and by applying the appropriate boundary conditions, the transcendental equations for the coupled and uncoupled modes are attained. Our results are applied to the study of the GaAs-GaP core-shell nanowire, for which we calculate numerically the polar optical modes, analyzing the role of strain in the vibrational properties of this nanosystem.

description: Obwohl Batch-Chromatographie viele Nachteile wie die ineffiziente Nutzung der Kapazität und hohe Leerlaufzeiten aufweist, überwiegt bisher der Einsatz im Vergleich zur kontinuierlichen Chromatographie. Vor allem unter dem Gesichtspunkt der hohen Prozesskosten im Bereich des Downstream Processings, würde der Einsatz von kontinuierlichen Methoden zu Produktivitätssteigerungen und damit zur Senkung der Prozesskosten führen. In dieser Arbeit wurde ein kontinuierliches Chromatographie-System entwickelt und nach dem Periodic-Counter-Current-Chromatographie (PCCC)-Prinzip in Betrieb genommen. Das System wurde für (Einweg-)Membranadsorber als Alternative zu Säulen ausgelegt und soll damit aufgrund des erhöhten konvektiven Massentransports zu weiteren Produktivitätssteigerungen führen. Zunächst wurde das System mit drei Membranadsorbern und schließlich mit vier Membranadsorbern zur Optimierung des Systems und Steigerung der Flexibilität betrieben. Durch das Beladungsprinzip der PCCC können die Membranadsorber über die dynamische Bindungskapazität hinaus beladen werden. Das führt z. B. zur besseren Kapazitätsnutzung, verringertem Pufferverbrauch und zur Steigerung der Raum-Zeit-Ausbeute. Im Rahmen dieser Arbeit wurden drei Applikationsbeispiele zur kontinuierlichen Aufreinigung mit dem PCCC-System untersucht: die Aufreinigung einer Candida antarctica Lipase B, einer Patchoulolsynthase und eines monoklonalen Antikörpers. Das System eignet sich vor allem für die Aufreinigung mittels Affinitätschromatographie, da hier das Prinzip der PCCC bestmöglich ausgenutzt wird. Für die drei Applikationsbeispiele wurden Produktivitätssteigerungen zwischen 20 und 50 % sowie eine Steigerung der Kapazitätsnutzung von 20 % erreicht. Generell kann jedoch keine pauschale Aussage über die zu erzielenden Steigerungen getroffen werden, sodass jeder Prozess individuell bewertet werden sollte.
