description: We investigate the distribution of the time spent by a random walker to the right of a boundary moving with constant velocity v. For the continuous-time problem (Brownian motion), we provide a simple alternative proof of Newman's recent result [J.Phys.A 34, L89 (2001)] using a method due to Kac. We then discuss the same problem for the case of a random walk in discrete time with an arbitrary distribution of steps, taking advantage of the general set of results due to Sparre Andersen. For the binomial random walk we analyse the corrections to the continuum limit on the example of the mean occupation time. The case of Cauchy-distributed steps is also studied.

description: We have used the upgraded Giant Metrewave Radio Telescope to carry out a deep (117 on-source hours) L-band observation of the Extended Groth Strip, to measure the average neutral hydrogen (HI) mass and median star formation rate (SFR) of star-forming galaxies, as well as the cosmic HI mass density, at $0.2 < z < 0.4$. This was done by stacking the HI 21cm emission and the rest-frame 1.4 GHz radio continuum from 445 blue star-forming galaxies with $\rm M_B \leq -17$ at $z_{\rm mean} \approx 0.34$. The stacked HI 21cm emission signal is detected at $\approx 7σ$ significance, implying an average HI mass of $\rm \langle M_{HI} \rangle = (4.93 \pm 0.70) \times 10^9 \: M_{\odot}$. We also stacked the rest-frame 1.4 GHz radio continuum emission of the same galaxies, to obtain a median SFR of $(0.54 \pm 0.06) \: {\rm M}_\odot$ yr$^{-1}$; this implies an average atomic gas depletion time scale of $\rm \langle Δt_{HI}\rangle \approx$ 9 Gyr, consistent with values in star-forming galaxies in the local Universe. This indicates that the star-formation efficiency does not change significantly over the redshift range $0 - 0.4$. We used the detection of the stacked HI 21cm emission signal to infer the normalized cosmic HI mass density $(\rm ρ_{HI}/ρ_{c,0})$ in star-forming galaxies at $z \approx 0.34$. Assuming the local relation between HI mass and absolute B-magnitude, we obtain $\rm ρ_{HI}/ρ_{c,0} = (4.81 \pm 0.75) \times 10^{-4}$, implying no significant evolution in $\rm ρ_{HI}/ρ_{c,0}$ from $z \approx 0.4$ to the present epoch.

description: Groenendijk and Stokhof (1984, 1996; Groenendijk 1999) provide a logically attractive theory of the semantics of natural language questions, commonly referred to as the partition theory. Two central notions in this theory are entailment between questions and answerhood. For example, the question "Who is going to the party?" entails the question "Is John going to the party?", and "John is going to the party" counts as an answer to both. Groenendijk and Stokhof define these two notions in terms of partitions of a set of possible worlds. We provide a syntactic characterization of entailment between questions and answerhood . We show that answers are, in some sense, exactly those formulas that are built up from instances of the question. This result lets us compare the partition theory with other approaches to interrogation -- both linguistic analyses, such as Hamblin's and Karttunen's semantics, and computational systems, such as Prolog. Our comparison separates a notion of answerhood into three aspects: equivalence (when two questions or answers are interchangeable), atomic answers (what instances of a question count as answers), and compound answers (how answers compose).

description: Entanglement of spin and position variables produced by spatially inhomogeneous magnetic fields of Stern-Gerlach type acting on spinor Bose-Einstein condensates may lead to interference effects at the level of one-boson densities. A model is worked out for these effects which is amenable to analytical calculation for gaussian shaped condensates. The resulting interference effects are sensitive to the spin polarization properties of the condensate.

description: Recent studies of rotating Rayleigh-Bénard convection at high rotation rates and strong thermal forcing have shown a significant discrepancy in total heat transport between experiments on a confined cylindrical domain on the one hand and simulations on a laterally unconfined periodic domain on the other. This paper addresses this discrepancy using direct numerical simulations on a cylindrical domain. An analysis of the flow field reveals a region of enhanced convection near the wall, the sidewall circulation. The sidewall circulation rotates slowly within the cylinder in anticyclonic direction. It has a convoluted structure, illustrated by mean flow fields in horizontal cross-sections of the flow where instantaneous snapshots are compensated for the orientation of the sidewall circulation before averaging. Through separate analysis of the sidewall region and the inner bulk flow, we find that for higher values of the thermal forcing the heat transport in the inner part of the cylindrical domain, outside the sidewall circulation region, coincides with the heat transport on the unconfined periodic domain. Thus the sidewall circulation accounts for the differences in heat transfer between the two considered domains, while in the bulk the turbulent heat flux is the same as that of a laterally unbounded periodic domain. Therefore, experiments, with their inherent confinement, can still provide turbulence akin to the unbounded domains of simulations, and at more extreme values of the governing parameters for thermal forcing and rotation. We also provide experimental evidence for the existence of the sidewall circulation that is in close agreement with the simulation results.

description: *Abbreviated abstract* Context: Brown dwarfs in the spectral range L9-T3.5, within the so called L/T transition, have been shown to be variable at higher amplitudes and with greater frequency than other field dwarfs. [...] Now, more variables such as these need to be discovered and studied to better constrain atmospheric models. This is also critical to better understand giant exoplanets and to shed light on a number of possible correlations between brown dwarf characteristics and variability. Aims: [...] In this work, we aim to discover new strong variables in this spectral range by targeting ten previously unsurveyed brown dwarfs. Methods: We used the NOTCam at the Nordic Optical Telescope to observe 11 targets, with spectral types ranging from L9.5 to T3.5, in the J-band [...] Results: We report first discoveries of strong and significant variability in four out of the ten targets [...] measuring peak-to-peak amplitudes up to 10.7 +- 0.4% in J for the T1 dwarf 2MASS J22153705+2110554, for which we observe significant light curve evolution between the 2017 and 2018 epochs. We also report a marginally significant detection of strong variability, and confirm that the well known 2MASS J01365662+0933473 is still strongly variable three years after the last reported epoch. Finally, we present an extensive multi-epoch catalogue of strong variables reported in the literature and discuss possible correlations that are identifiable from the catalogue. Conclusions: We significantly add to the number of known strong variables, and through Poisson statistics infer an occurrence rate for strong variability among L9-T3.5 brown dwarfs of 40[+32-19]%, which is in agreement with previous estimates. The new variables identified in this work are also excellently suited for extensive multi-wavelength observations dedicated to probing the 3D structure of brown dwarf atmospheres.

description: We calculate the dynamic structure factor S(k,omega) of liquid Ge (l-Ge) at temperature T = 1250 K, and of amorphous Ge (a-Ge) at T = 300 K, using ab initio molecular dynamics. The electronic energy is computed using density-functional theory, primarily in the generalized gradient approximation, together with a plane wave representation of the wave functions and ultra-soft pseudopotentials. We use a 64-atom cell with periodic boundary conditions, and calculate averages over runs of up to 16 ps. The calculated liquid S(k,omega) agrees qualitatively with that obtained by Hosokawa et al, using inelastic X-ray scattering. In a-Ge, we find that the calculated S(k,omega) is in qualitative agreement with that obtained experimentally by Maley et al. Our results suggest that the ab initio approach is sufficient to allow approximate calculations of S(k,omega) in both liquid and amorphous materials.

description: We present the X-ray analysis of the largest flux-limited complete sample of blazar candidates at z>4 selected from the Cosmic Lens All Sky Survey (CLASS). After obtaining a nearly complete (24/25) X-ray coverage of the sample (from Swift-XRT, XMM-Newton and Chandra), we analysed the spectra in order to identify the bona-fide blazars. We classified the sources based on the shape of their Spectral Energy Distributions (SEDs) and, in particular, on the flatness of the X-ray emission and its intensity compared to the optical one. We then compared these high-z blazars with a blazar sample selected at lower redshifts (z~1). We found a significant difference in the X-ray-to-radio luminosity ratios, with the CLASS blazars having a mean ratio 2.4+/-0.5 times larger than low-z blazars. We tentatively interpret this evolution as due to the interaction of the electrons of the jet with the Cosmic Microwave Background (CMB) photons, which is expected to boost the observed X-ray emission at high redshifts. Such a dependence has been already observed in highly radio-loud AGNs in the recent literature. This is the first time it is observed using a statistically complete radio flux limited sample of blazars. We have then evaluated whether this effect could explain the differences in the cosmological evolution recently found between radio and X-ray selected samples of blazars. We found that the simple version of this model is not able to solve the tension between the two evolutionary results.

 Diagnosis. The following set of features may be used to diagnose females of C. laevigena among the Tibetan Colletes: malar area as long as basal width of mandible, mesoscutal black hairs present and hind basitarsus with dark setae. Males are diagnosable through the combination of malar area 1.5× as long as basal width of mandible, paraocular area without black hairs and metasoma with well-defined apical bands. Colletes laevigena most closely resembles C. pseudolaevigena, but their females can be differentiated by the clypeus without groove in the former (clypeus with a longitudinal groove in the latter) and the hind basitarsus with dark setae in the former (hind basitarsus with pale setae in the latter). Males of C. laevigena are distinct in having the hind basitarsus 5.0× (hind basitarsus 4.0× as long as broad in C. pseudolaevigena) and the gonostylus 2.0× as long as its basal width in C. laevigena (gonostylus as long as its basal width in C. pseudolaevigena).

description: The structure of scattering amplitudes in supergravity theories continues to be of interest. Recently, the amplitude for $2\rightarrow 2$ scattering in ${\cal N}=8$ supergravity was presented at three-loop order for the first time. The result can be written in terms of an exponentiated one-loop contribution, modulo a remainder function which is free of infrared singularities, but contains leading terms in the high energy Regge limit. We explain the origin of these terms from a well-known, unitarity-restoring exponentiation of the high-energy gravitational $S$-matrix in impact-parameter space. Furthermore, we predict the existence of similar terms in the remainder function at all higher loop orders. Our results provide a non-trivial cross-check of the recent three-loop calculation, and a necessary consistency constraint for any future calculation at higher loops.

description: The Atmospheric Chemistry Suite (ACS) instrument onboard the ExoMars Trace Gas Orbiter (TGO) ESA-Roscosmos mission began science operations in March 2018. ACS Mid InfraRed (MIR) channel notably provides solar occultation observations of the martian atmosphere in the 2.3 - 4.2 $μ$m spectral range. Here we use these observations to characterize water ice clouds before and during the MY 34 Global Dust Storm (GDS). We developed a method to detect water ice clouds with mean particle size $\leq$ 2 $μ$m, and applied it to observations gathered between $L_s=165^\circ$ and $L_s=243^\circ$. We observe a shift in water ice clouds maximum altitudes from about 60 km before the GDS to above 90 km during the storm. These very high altitude, small-sized ($r_\mathrm{eff} \leq 0.3$ $μ$m) water ice clouds are more frequent during MY34 compared to non-GDS years at the same season. Particle size frequently decreases with altitude, both locally within a given profile and globally in the whole dataset. We observe that the maximum altitude at which a given size is observed can increase during the GDS by several tens of km for certain sizes. We notably notice some large water ice particles ($r_\mathrm{eff}\geq1.5$ $μ$m) at surprisingly high altitudes during the GDS (50 - 70 km). These results suggest that GDS can significantly impact the formation and properties of high altitude water ice clouds as compared to the usual perihelion dust activity.

We prove this characterization by translating the logic of interrogation to classical predicate logic and applying Craig's interpolation theorem.

description: Real-time large-scale crowd simulations with realistic behavior, are important for many application areas. On CPUs, the ORCA pedestrian steering model is often used for agent-based pedestrian simulations. This paper introduces a technique for running the ORCA pedestrian steering model on the GPU. Performance improvements of up to 30 times greater than a multi-core CPU model are demonstrated. This improvement is achieved through a specialized linear program solver on the GPU and spatial partitioning of information sharing. This allows over 100,000 people to be simulated in real time (60 frames per second).

description: Considerable progress has been achieved recently in the experimental investigation of quadrupole-collective isovector excitations in the valence shell, the so called mixed-symmetry states (MSSs), in the mass A ≈ 130 region. This is due to a new experimental technique for study MSSs which is based on the observation of low-multiplicity γ-ray events from inverse kinematics Coulomb excitation with the large 4π spectrometer, such as Gammasphere. The obtained experimental information for the MSSs of stable N = 80 isotones indicates that for low-collective vibrational nuclei the underlying single-particle structure can be the most important factor for preserving or fragmenting the MSSs through the mechanism of shell stabilization. The evolution of the MSSs from ¹³⁴Xe to ¹³⁸Ce is also used to determine the local strength of the proton-neutron interaction derived for first time from states with symmetric and antisymmetric nature.

Affinity Cleavage of Double-Stranded DNA Directed by a RecA Nucleoprotein Filament Containing an Oligonucleotide-EDTA•Fe(II)
Creators: name: Singleton, Jennifer Wales
Publisher: name: California Institute of Technology
Year: 1994
Subjects: Chemistry

description: Escherichia coli RecA protein promotes strand exchange between two homologous DNAs by polymerizing on single-stranded DNA to form nucleoprotein filaments which then bind to a homologous sequence of duplex DNA. Joint formation between the RecA protein and three strands of DNA is followed by strand exchange in which the original single strand is inserted into the duplex while the homologous duplex strand is displaced out. The structures of the strand exchange intermediates formed by the RecA protein have not been elucidated. We review studies aimed at determining such structures and we report the use of affinity cleaving techniques to probe the structure of the joint molecule formed between a RecA-oligonucleotide filament and duplex DNA by incorporating a thymidine-EDTA•Fe (T*) into the oligonucleotide of the filament. In our study, we find that the nucleoprotein filament binds antiparallel to the complementary strand within the homologous sequence of DNA and that it is associated more strongly with the complementary strand than with the homologous strand of the duplex.

description: Carbon has numerous one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D) allotropic structures. The study of carbon materials has been a major focus of material science and condensed matter physics. Previous studies have identified different classes of topological semimetallic carbon allotropes with different topological phases. In this review, we first give a brief summary of the development of carbon allotropes from 1D to 3D. Next, we discuss topological properties of carbon materials and their physical origin. Then, we consider possible expansion of the topological study of carbon materials to other light-element materials such as boron. Finally, we present future prospects in pursue of topological physics within carbon allotropes.
title: Transparente Randbedingungen für längshomogene Wellenleiterstrukturen

description: Berechnungen und Simulationen der Ausbreitung elektromagnetischer Wellen entlang längshomogener Wellenleiter werden mithilfe zweidimensionaler Diskretisierungsverfahren durchgeführt. Abhängig von der Anwendung werden entsprechende numerische Randbedingungen verwendet. Diese lassen sich bei transversal offenen Wellenleitern durch geschlossene oder absorbierende Randbedingungen annähern, was zur Verfälschung des realen Modells führt. Die in dieser Arbeit vorgestellte Methode zur Modellierung von offenen Randbedingungen basiert auf dem Kirchhoff-Integral und wurde für das Diskretisierungsverfahren FIT implementiert. Die vorgestellte Randbedingung wird mit ausgewählten konventionellen Lösungsansätzen verglichen.

description: The pair correlations in mesoscopic systems such as $nm$-size superconducting clusters and nuclei are studied at finite temperature for the canonical ensemble of fermions in model spaces with a fixed particle number: i) a degenerate spherical shell (strong coupling limit), ii) an equidistantly spaced deformed shell (weak coupling limit). It is shown that after the destruction of the pair correlations at T=0 by a strong magnetic field or rapid rotation, heating can bring them back. This phenomenon is a consequence of the fixed number of fermions in the canonical ensemble.

description: Report on the bottlenecks that would hinder the efficient usage of Nordic ESMs on EuroHPC and possible remediation actions (I/Os, adding GPU support, etc.) with clear information on costs in terms of manpower. Task leader: Alok Gupta Project manager: Anne Fouilloux Work Package leader: Jean Iaquinta Internal reviewer: Oskar Landgren Summary and outcomes: ESMs used in the Nordic countries are clearly not ready for EuroHPC and very little dedicated funding from the scientific community is used for porting existing codes to future architectures. Providers have hired several specialists to support the scientific community but the commitment from the scientific community is not there. Exchange of knowledge of involved staff (scientists, RSEs, technical support) would be very helpful. For instance, being able to organize meetings/hackathons (online or face to face) with both experts from NorESM and EC-EARTH has been highlighted as an important requirements by those involved in the GPU hackathon. Code refactoring and best software practices are the most important component for efficient usage of new architecture, including EuroHPC.

description: Neural Ordinary Differential Equations (N-ODEs) are a powerful building block for learning systems, which extend residual networks to a continuous-time dynamical system. We propose a Bayesian version of N-ODEs that enables well-calibrated quantification of prediction uncertainty, while maintaining the expressive power of their deterministic counterpart. We assign Bayesian Neural Nets (BNNs) to both the drift and the diffusion terms of a Stochastic Differential Equation (SDE) that models the flow of the activation map in time. We infer the posterior on the BNN weights using a straightforward adaptation of Stochastic Gradient Langevin Dynamics (SGLD). We illustrate significantly improved stability on two synthetic time series prediction tasks and report better model fit on UCI regression benchmarks with our method when compared to its non-Bayesian counterpart.

 Colletes annejohnae Kuhlmann, 2003b: 727 (holotype ♀: Kazakhstan, 30km ENE of Shelek [OÖLM]).
 Colletes annejohnae; Kuhlmann 2005: 1369; 2009a: 16; Kuhlmann & Proshchalykin 2013a: 417, 2015: 97, 2018: 6; Niu et al. 2014b: 469; Ascher & Pickering 2021.
 Diagnosis. Colletes annejohnae cannot be confused with any species of the genus found in Xizang due to its remarkably short malar area, which is only 0.3× as long as basal width of mandible in males and virtually absent in females. Females of C. annejohnae are also unique in having the T1 covered with off-white dense tomentum anteriorly (in all other females the anterior area of T1 has either erect pubescence only or erect hairs intermixed with sparse appressed ones). Males of C. annejohnae can be further differentiated from those of the Tibetan Colletes by their pale-brown wing venation (wing venation is always dark-brown to black in the other males).

 Distribution. Relatively broadly distributed in Central Asia (Kazakhstan, Kyrgyzstan and Uzbekistan) and ranging as far east as western China (Xinjiang).

 Remarks. Colletes annejohnae is known to be endemic to steppic regions of Central Asia and western China; therefore, the fact that we did not find it among the new material examined by us is not surprising. The species has nonetheless been recorded from Xizang previously (Ascher & Pickering 2021), which is why it is included in the scope of this paper. However, its occurrence there could not be confirmed by us because the source specimens cannot be located in the AMNH (C. Smith, pers. comm.), where they are supposedly deposited.

Why current-carrying magnetic flux tubes gobble up plasma and become thin as a result

description: It is shown that if a current-carrying magnetic flux tube is bulged at its axial midpoint z=0 and constricted at its axial endpoints z=+h,-h, then plasma will be accelerated from z=+h,-h towards z=0 resulting in a situation similar to two water jets pointed at each other. The ingested plasma convects embedded, frozen-in toroidal magnetic flux from z=+h,-h to z=0. The counter-directed flows collide and stagnate at z=0 and in so doing (i) convert their translational kinetic energy into heat, (ii) increase the plasma density at z~0, and (iii) increase the embedded toroidal flux density at z~0. The increase in toroidal flux density at z~0 increases the toroidal field Bphi and hence increases the magnetic pinch force at z~0 and so causes a reduction of the flux tube radius at z~0. Thus, the flux tube develops an axially uniform cross-section, a decreased volume, an increased density, and an increased temperature. This model is proposed as a likely hypothesis for the long-standing mystery of why solar coronal loops are observed to be axially uniform, hot, and bright.
