description: Understanding the carrier excitation and transport processes at the single-charge level plays a key role in quantum-dot-based solar cells and photodetectors. Here, we report on Coulomb-induced giant photocurrent enhancement of positive charged trions (\emph{X$^+$}) in a single self-assembled InAs/GaAs quantum dot embedded in an \emph{n-i-}Schottky device by high-resolution photocurrent (PC) spectroscopy. The Coulomb repulsion between the two holes in the \emph{X$^+$} increases the tunneling rate of the hole, and the remaining hole can be reused as the initial state to regenerate \emph{X$^+$} again. This process brings the PC amplitude of \emph{X$^+$} up to 30 times larger than that of the neutral exciton. The analysis of the hole tunneling time gives the equivalent change of hole tunnel barriers caused by Coulomb interaction between two holes with a value of 8.05 meV during the tunneling process. Our work brings a fundamental understanding of energy conversion for solar cells in nanoscale to improve internal quantum efficiency for energy harvesting.

description: In recent work, we showed that non-perturbative vacuum effects of a very low mass particle could induce, at a redshift of order 1, a transition from a matter-dominated to an accelerating universe. In that work, we used the simplification of a sudden transition out of the matter-dominated stage and were able to fit the Type Ia supernovae (SNe-Ia) data points with a spatially-open universe. In the present work, we find a more accurate, smooth {\it spatially-flat} analytic solution to the quantum-corrected Einstein equations. This solution gives a good fit to the SNe-Ia data with a particle mass parameter $m_h$ in the range $6.40 \times 10^{-33}$ eV to $7.25 \times 10^{-33}$ eV. It follows that the ratio of total matter density (including dark matter) to critical density, $Ø_0$, is in the range 0.58 to 0.15, and the age $t_0$ of the universe is in the range $8.10 h^{-1}$ Gyr to $12.2 h^{-1}$ Gyr, where $h$ is the present value of the Hubble constant, measured as a fraction of the value 100 km/(s Mpc). This spatially-flat model agrees with estimates of the position of the first acoustic peak in the small angular scale fluctuations of the cosmic background radiation, and with light-element abundances of standard big-bang nucleosynthesis. Our model has only a single free parameter, $m_h$, and does not require that we live at a special time in the evolution of the universe.

description: We present a detailed study of different exchange-correlation (xc) functionals in describing the dynamical properties of finite systems. For that purpose, we calculated the static polarizabilities, ionization potentials and optical absorption spectrum of four small clusters, Na_2, Na_4, SiH_4 and Si_2H_6, using a real-space, real-time technique. The computed static polarizabilities and ionization potentials seem to be in rather good agreement with the available experimental data, once the proper asymptotics of the potential are taken into account. The same conclusion holds for the absorption spectra, although the xc kernels in use do not provide a sufficiently strong attractive interaction between electrons and holes, leading to spectra slightly shifted towards higher energies. This deficiency is traced back to the insufficient description of dynamical effects in the correlation functional. Furthermore, it is shown that the xc potential used to obtain the ground state is the key factor to get reasonable spectra, whereas the choice of the xc kernel just amounts to small, although important, quantitative changes.

description: The statistical properties of coherent radiation scattered from phase-ordering materials are studied in detail using large-scale computer simulations and analytic arguments. Specifically, we consider a two-dimensional model with a nonconserved, scalar order parameter (Model A), quenched through an order-disorder transition into the two-phase regime. For such systems it is well established that the standard scaling hypothesis applies, consequently the average scattering intensity at wavevector _k and time t' is proportional to a scaling function which depends only on a rescaled time, t ~ |_k|^2 t'. We find that the simulated intensities are exponentially distributed, with the time-dependent average well approximated using a scaling function due to Ohta, Jasnow, and Kawasaki. Considering fluctuations around the average behavior, we find that the covariance of the scattering intensity for a single wavevector at two different times is proportional to a scaling function with natural variables mt = |t_1 - t_2| and pt = (t_1 + t_2)/2. In the asymptotic large-pt limit this scaling function depends only on z = mt / pt^(1/2). For small values of z, the scaling function is quadratic, corresponding to highly persistent behavior of the intensity fluctuations. We empirically establish a connection between the intensity covariance and the two-time, two-point correlation function of the order parameter. This connection allows sensitive testing, either experimental or numerical, of existing theories for two-time correlations in systems undergoing order-disorder phase transitions. Comparison between theory and our numerical results requires no adjustable parameters.

description: Genus Zelotes Gistel, 1848
 Comments. With 398 valid species, Zelotes is the most speciose genus of the family (WSC, 2022). Although it has never been the subject of a global revision, over the last five decades more than 200 species previously classified in this genus have been transferred to other genera, including new ones: Aponetius Kamura, 2020, Civizelotes Senglet, 2012, Heser Tuneva 2004, and Marinarozelotes Ponomarev, 2020. Still, judging by the shape of the copulatory organs, the genus remains polyphyletic. One of the more distinct species groups that does not bear much similarity to the generotype is the puritanus group, which accommodates at least ten species known primarily from the Palaearctic (one species has a Holarctic range) (Fomichev & Marusik, 2021): Z. anatolyi Fomichev & Marusik, 2021, Z. gussakovskyi Charitonov, 1951, Z. khatlonicus Fomichev & Marusik, 2021, Z. mikhailovi Marusik, 1995, Z. parascrutatus Levy, 1998, Z. potanini Schenkel, 1963, Z. puritanus Chamberlin, 1922, Z. scrutatus O. Pickard-Cambridge, 1872, Z. zin Levy, 1998 and possibly Z. hummeli Schenkel, 1963. This group is characterized by solid, anteriorly rounded wide epigynal pockets (= hoods), elongate epigynal fovea rounded posteriorly, blunt tibial apophysis, and embolus covered by the “intercalary” sclerite (= part of embolic division). The new species described herein belongs to this species-group.

Interplay between phonons and anisotropic elasticity drives negative thermal expansion in PbTiO$_3$

description: We use first-principles theory to show that the ingredients assumed to be essential to the occurrence of negative thermal expansion (NTE) -- rigid unit phonon modes with negative Grüneisen parameters -- are neither sufficient nor necessary for a material to undergo NTE. Instead, we find that NTE in PbTiO$_3$ involves a delicate interplay between the phonon properties of a material (Grüneisen parameters) and its anisotropic elasticity. These unique insights open new avenues in our fundamental understanding of the thermal properties of materials, and in the search for NTE in new materials classes.

description: Anxiety is one of the most complicated and widespread mental health conditions, and effective treatment of anxiety disorders is vital to public health. Investigating the mechanisms that are linked to and contribute to anxiety disorders, such as intolerance of uncertainty (IU), a transdiagnostic factor of all anxiety disorders, may be an appropriate approach for a better understanding of anxiety disorders. Furthermore, examining the role of resilience, which has a protective function in mental health conditions, could contribute to improving our understanding of anxiety and treatment. This thesis investigates the impact of mindfulness-based interventions (MBI), on anxiety, IU, and resilience. The primary research question of this thesis was 'What is the role of MBI on anxiety disorders, IU, and resilience?' Four different studies were carried out to address this question. Study one consists of a systematic review examining the impact of MBIs on anxiety and IU and evidence from the literature. The findings confirmed the association between IU and anxiety and showed that common interventions for anxiety are effective in reducing IU and anxiety symptoms. Results also suggested that targeting IU in treatment may be beneficial. Secondly, a small qualitative study was performed to examine anxious individuals' opinions about anxiety, common coping mechanisms, common treatments, and views on IU and resilience. The second study provides insight into the experience of anxiety, coping mechanisms and treatments. The study revealed that mindfulness was not well known as an approach and there was dissatisfaction with more standard treatments. Thirdly a quantitative study was conducted to understand whether mindfulness has a role in the relationship between anxiety and uncertainty with a larger sample. Findings demonstrated that mindfulness plays a mediating role between anxiety and IU. Finally, a case study was conducted to test an MBI on an anxious individual and to investigate the strengths and weaknesses of this intervention. Results showed that MBI is effective in changing anxiety symptoms, IU, and resilience. Collectively, these findings provide evidence that mindfulness has an important role in anxiety, IU, and resilience. A targeted MBI may reduce anxiety symptoms and increase psychological resilience.

A comment on baryogenesis at the electroweak scale in alternative cosmologies

description: In this study we examine post-inflationary cosmologies dominated by a scalar field with the equation of state: p_phi=w_phi rho_phi (0 leq w_phi leq 1) in order to facilitate baryogenesis at the electroweak scale. We take a more conventional approach from one in Ref. 1 [Joyce, Prokopec] and assume that the Universe reheats by the scalar field decay before the nucleosynthesis epoch, and find a larger expansion rate at the electroweak scale than the one obtained in Ref. 1. The decaying field models suffer however from an entropy release that dilutes the baryon number produced at the electroweak scale. This dilution is minimized when the kinetic scalar field mode dominates (w_phi = 1), singling it out as the preferred cosmology with regard to baryogenesis. We study both cases, the electroweak transition with an expansion driven departure from equilibrium, and a first order phase transition. We show that in the former case with some tuning one can produce the amount of matter consistent with observation. In the latter case the expansion rate at the electroweak scale may be almost as large as the symmetric phase sphaleron rate, so that even the electroweak models with a relatively weak first order phase transition can be viable for baryogenesis.

description: Thermodynamic quantities and correlation functions (CFs) of the classical antiferromagnet on the checkerboard lattice are studied for the exactly solvable infinite-component spin-vector model, $D \to \infty$. In contrast to conventional two-dimensional magnets with continuous symmetry showing extended short-range order at distances smaller than the correlation length, $r \lesssim ξ_c \propto \exp(T^*/T)$, correlations in the checkerboard-lattice model decay already at the scale of the lattice spacing due to the strong degeneracy of the ground state characterized by a macroscopic number of strongly fluctuating local degrees of freedom. At low temperatures, spin CFs decay as $ \propto 1/r^2$ in the range $a_0 \ll r \ll ξ_c \propto T^{-1/2}$, where $a_0$ is the lattice spacing. Analytical results for the principal thermodynamic quantities in our model are very similar with MC simulations, exact and analytical results for the classical Heisenberg model (D=3) on the pyrochlore lattice. This shows that the ground state of the infinite-component spin vector model on the checkerboard lattice is a classical spin liquid.

description: We propose a double obstacle phase field methodology for binary recovery of the slowness function of an Eikonal equation found in first traveltime tomography. We treat the inverse problem as an optimization problem with quadratic misfit functional added to a phase field relaxation of the perimeter penalization functional. Our approach yields solutions as we account for well posedness of the forward problem by choosing regular priors. We obtain a convergent finite difference and mixed finite element based discretization and a well defined descent scheme by accounting for the non-differentiability of the forward problem. We validate the phase field technique with a $Γ$ - convergence result and numerically by conducting parameter studies for the scheme, and by applying it to a variety of test problems with different geometries, boundary conditions, and source - receiver locations.

description: A half-square of a bipartite graph $B=(X,Y,E_B)$ has one color class of $B$ as vertex set, say $X$; two vertices are adjacent whenever they have a common neighbor in $Y$. If $G=(V,E_G)$ is the half-square of a planar bipartite graph $B=(V,W,E_B)$, then $G$ is called a map graph, and $B$ is a witness of $G$. Map graphs generalize planar graphs, and have been introduced and investigated by Chen, Grigni and Papadimitriou [STOC 1998, J. ACM 2002]. They proved that recognizing map graphs is in $\mathsf{NP}$ by proving the existence of a witness. Soon later, Thorup [FOCS 1998] claimed that recognizing map graphs is in $\mathsf{P}$, by providing an $Ω(n^{120})$-time algorithm for $n$-vertex input graphs. In this note, we give good characterizations and efficient recognition for half-squares of bipartite graphs with girth at least a given integer $g\ge 8$. It turns out that map graphs having witnesses of girth at least $g$ are precisely the graphs whose vertex-clique incidence bipartite graph is planar and of girth at least $g$. Our structural characterization implies an $O(n^2m)$-time algorithm for recognizing if a given $n$-vertex $m$-edge graph $G$ is such a map graph.

Väter im Familienalltag – Determinanten einer aktiven Vaterschaft

description: “New” or “active” fatherhood is increasingly discussed in the family research literature, yet it is unclear what these terms entail, and which factors associate with the practice of such “active fatherhood”. With the “AID:A II” survey (Growing Up in Germany: Everyday Life, Wave 2) the present paper uses the most up-to-date data that chart fathers’ everyday activities for and with their children. A composite indicator for “active fatherhood” was built and the key determinants of father involvement were then explored. The results suggest that the employment of both parents play an important role: The more hours the father has to work beyond full-time working hours, the less likely the father is to be actively involved in childcare. Longer maternal working hours and greater proportional contribution of the mother to the family income, instead, make an active fatherhood more likely. In addition, the satisfaction with couple relationship as well as the gender concept of both parents are significant predictors of father involvement. Zusammenfassung Von den ‚neuen‘ oder auch ‚aktiven Vätern‘ wird heute viel gesprochen, wenngleich oft unklar bleibt, was diese kennzeichnet und von welchen Determinanten die Ausübung einer solchen aktiven Vaterschaft abhängt. Mit dem DJI-Survey AID:A II liegen nun aktuelle Daten vor, anhand derer für den vorliegenden Beitrag Alltagsaktivitäten von Vätern für und mit ihren Kindern in den Blick genommen und daraus ein Index ‚aktiver Vaterschaft‘ erstellt werden konnten. Anschließend konnten so die wichtigsten Determinanten einer aktiven Vaterschaft untersucht werden. Wie die Befunde zeigen, spielt dabei die Erwerbstätigkeit beider Partner eine bedeutende Rolle: Je mehr Überstunden die Väter über ihre normale Vollzeitwoche hinaus leisten müssen, desto geringer sind die Chancen, sich aktiv in Betreuung und Erziehung der Kinder einbringen zu können. Ein höherer Erwerbsumfang der Mütter sowie ein größerer Anteil am erwirtschafteten Haushaltseinkommen hingegen fördern eine ‚aktive Vaterschaft‘. Deutlich wird darüber hinaus die große Bedeutung der Partnerschaftsqualität sowie der Genderkonzepte beider Partner.

description: In this paper we construct the BPS black hole generating solution of toroidally compactified string (and M) theory, giving for it both the macroscopic and microscopic description. Choosing a proper U-duality gauge the latter will be given by a bound state made solely of D-branes. The axionic nature of the supergravity solution will be directly related to non-trivial angles between the constituent D-branes (type IIB configuration) or, in a T-dual gauge, to the presence of magnetic flux on constituent D-brane world volumes (type IIA configuration). As expected, the four dimensional axion fields arise from the dimensional reduction of non-diagonal metric tensor components or Kalb-Ramond B field components for type IIB or type IIA cases, respectively. Thanks to this result it is then now possible to fill the full 56-dimensional U-duality orbit of N=8 BPS black holes and to have a macroscopic and microscopic description of all of them.

Relativistic effects are included by means of energy-consistent pseudopotentials, correlations are treated at the coupled-cluster level. A striking deficiency of the Hartree-Fock approach are lattice constants deviating by up to 7.5 % from experimental values which is reduced to a maximum error of 2.4 % by taking into account electron correlation. Besides, we provide ab-initio data for in-crystal polarizabilities and van der Waals coefficients.

description: Electron transport in a finite one dimensional quantum spin chain (with ferromagnetic exchange) is studied within an $s-d$ exchange Hamiltonian. Spin transfer coefficients strongly depend on the sign of the $s-d$ exchange constant. For a ferromagnetic coupling, they exhibit a novel resonant pattern, reflecting the salient features of the combined electron-spin system. Spin-flip processes are inelastic and feasible at finite voltage or at finite temperature.

Creating retrogradely orbiting planets by prograde stellar fly-bys

description: Several planets have been found that orbit their host star on retrograde orbits (spin-orbit angle ϕ > 90°). Currently, the largest measured projected angle between the orbital angular momentum axis of a planet and the rotation axis of its host star has been found for HAT-P-14b to be $\approx$ 171°. One possible mechanism for the formation of such misalignments is through long-term interactions between the planet and other planetary or stellar companions. However, with this process, it has been found to be difficult to achieve retrogradely orbiting planets, especially planets that almost exactly counter-orbit their host star (ϕ $\approx$ 180°) such as HAT-P-14b. By contrast, orbital misalignment can be produced efficiently by perturbations of planetary systems that are passed by stars. Here we demonstrate that not only retrograde fly-bys, but surprisingly, even prograde fly-bys can induce retrograde orbits. Our simulations show that depending on the mass ratio of the involved stars, there are significant ranges of planetary pre-encounter parameters for which counter-orbiting planets are the natural consequence. We find that the highest probability to produce counter-orbiting planets ($\approx$ 20%) is achieved with close prograde, coplanar fly-bys of an equal-mass perturber with a pericentre distance of one-third of the initial orbital radius of the planet. For fly-bys where the pericentre distance equals the initial orbital radius of the planet, we still find a probability to produce retrograde planets of $\approx$ 10% for high-mass perturbers on inclined (60° < i < 120°) orbits. As usually more distant fly-bys are more common in star clusters, this means that inclined fly-bys probably lead to more retrograde planets than those with inclinations < 60°. (...)

description: The true and eccentric anomaly parametrizations of the Kepler motion are generalized to quasiperiodic orbits, by considering perturbations of the radial part of the kinetic energy in a form of a series of negative powers of the orbital radius. A toolchest of methods for averaging observables as functions of the energy $E$ and angular momentum $L$ is developed. A broad range of systems governed by the generic Brumberg force and recent applications in the theory of gravitational radiation involve integrals of these functions over a period of motion. These integrals are evaluated by using the residue theorem. In the course of this work two important questions emerge: (1) When does the true and eccentric anomaly parameter exist? (2) Under what circumstances and why are the poles in the origin? The purpose of this paper is to find the answer to these queries.

 Family Hersiliidae Thorell, 1870
 Genus Hersiliola Thorell, 1870
 Comments. The genus is rather well studied in the Middle East thanks to several regional revisions and smaller taxonomic contributions (e. g. Foord & DippenaarSchoeman, 2005; Danışman et al., 2012; Marusik & Fet, 2009; Mirshamsi et al., 2016; Zamani et al., 2017). Six species are currently known from the Middle East (WSC, 2022). The new species described herein represents the first record of Hersiliola in Iraq.

description: We present a new method for the classification of transient noise signals (or glitches) in advanced gravitational-wave interferometers. The method uses learned dictionaries (a supervised machine learning algorithm) for signal denoising, and untrained dictionaries for the final sparse reconstruction and classification. We use a data set of 3000 simulated glitches of three different waveform morphologies, comprising 1000 glitches per morphology. These data are embedded in non-white Gaussian noise to simulate the background noise of advanced LIGO in its broadband configuration. Our classification method yields a 96% accuracy for a large range of initial parameters, showing that learned dictionaries are an interesting approach for glitch classification. This work constitutes a preliminary step before assessing the performance of dictionary-learning methods with actual detector glitches.

Single-Particle Green Functions in Exactly Solvable Models of Bose and Fermi Liquids

description: Based on a class of exactly solvable models of interacting bose and fermi liquids, we compute the single-particle propagators of these systems exactly for all wavelengths and energies and in any number of spatial dimensions. The field operators are expressed in terms of bose fields that correspond to displacements of the condensate in the bose case and displacements of the fermi sea in the fermi case. Unlike some of the previous attempts, the present attempt reduces the answer for the spectral function in any dimension in both fermi and bose systems to quadratures. It is shown that when only the lowest order sea-displacement terms are included, the random phase approximation in its many guises is recovered in the fermi case, and Bogoliubov's theory in the bose case. The momentum distribution is evaluated using two different approaches, exact diagonalisation and the equation of motion approach. The novelty being of course, the exact computation of single-particle properties including short wavelength behaviour.

description: 1D stellar evolution codes employ rudimentary treatments of turbulent convection. For stars with convective envelopes, this leads to systematic errors in the predicted oscillation frequencies needed for asteroseismology. One way of mending these structural inadequacies is through patching, whereby the outermost layers of 1D models are replaced by the mean stratifications from 3D simulations. In order to viably implement this approach in asteroseismic analysis, interpolation throughout precomputed 3D envelopes is required. We present a method that interpolates throughout precomputed 3D envelopes as a function of effective temperature, surface gravity, and metallicity. We conduct a series of validation tests that demonstrate that the scheme reliably and accurately reproduces the structures of stellar envelopes and apply our method to the Sun as well as two stars observed by Kepler. We parameterize the frequency shift that results from patching and show that the functional forms are evolutionary dependent. In addition we find that neglecting modal effects, such as non-adiabatic energetics, introduces systematic errors in asteroseimically obtained stellar parameters. Both these results suggest that a cautious approach is necessary when utilizing empirical surface corrections in lieu of patching models. Our results have important implications, particularly for characterizing exoplanet systems, where accuracy is of utmost concern.

Suggesting Cooking Recipes Through Simulation and Bayesian Optimization

description: Cooking typically involves a plethora of decisions about ingredients and tools that need to be chosen in order to write a good cooking recipe. Cooking can be modelled in an optimization framework, as it involves a search space of ingredients, kitchen tools, cooking times or temperatures. If we model as an objective function the quality of the recipe, several problems arise. No analytical expression can model all the recipes, so no gradients are available. The objective function is subjective, in other words, it contains noise. Moreover, evaluations are expensive both in time and human resources. Bayesian Optimization (BO) emerges as an ideal methodology to tackle problems with these characteristics. In this paper, we propose a methodology to suggest recipe recommendations based on a Machine Learning (ML) model that fits real and simulated data and BO. We provide empirical evidence with two experiments that support the adequacy of the methodology.
a-b plane optical conductivity in YBa_2Cu_3O_{7-delta} above and below T*

description: Analysis of the a-b plane optical conductivity $σ_{ab}$ for both twinned and untwinned YBa$_{2}$Cu$_{3}$O$_{7-δ}$ as a function of temperature and doping shows that below a well defined temperature T*, a dip in the spectrum systematically appears separating the infrared charge excitation spectrum into two components with distinct energy scales. The change from monotonic behaviour in $σ_{ab}$ is found to be concurrent with the onset of phonon anomalies in Raman and infrared spectra below T*. The optical data are suggested to be evidence for the appearance of an inhomogeneous distribution of carriers rather than the opening of a simple gap for charge excitations below T*, an interpretation wich is consistent with recent angle-resoved photoemission and electronic Raman spectra. We find that the behaviour below T* and the absence of any anomalies at Tc can be interpreted assuming a Bose-Einstein condensation of preformed pairs.
