description: Non-coplanar spin textures with scalar spin chirality can generate effective magnetic field that deflects the motion of charge carriers, resulting in topological Hall effect (THE), a powerful probe of the ground state and low-energy excitations of correlated systems. However, spin chirality fluctuation in two-dimensional ferromagnets with perpendicular anisotropy has not been considered in prior studies. Herein, we report direct evidence of universal spin chirality fluctuation by probing the THE above the transition temperatures in two different ferromagnetic ultra-thin films, SrRuO$_3$ and V doped Sb$_2$Te$_3$. The temperature, magnetic field, thickness, and carrier type dependences of the THE signal, along with our Monte-Carlo simulations, unambiguously demonstrate that the spin chirality fluctuation is a universal phenomenon in two-dimensional Ising ferromagnets. Our discovery opens a new paradigm of exploring the spin chirality with topological Hall transport in two-dimensional magnets and beyond

description: Several fungi belonging to the genus Psilocybe, also called “magic mushrooms”, contain the hallucinogenic drugs psilocybin and psilocin. They are chemically related to serotonin (5-HT). In addition to being abused as drugs, they are now also being discussed or used as a treatment option for depression. Here, we hypothesized that psilocybin and psilocin may act also on cardiac serotonin receptors and studied them in vitro in atrial preparations of our transgenic mouse model with cardiac myocytes-specific overexpression of the human 5-HT4 receptor (5-HT4-TG) as well as in human atrial preparations. Both psilocybin and psilocin enhanced the force of contraction in isolated left atrial preparations from 5-HT4-TG, increased the beating rate in isolated spontaneously beating right atrial preparations from 5-HT4-TG and augmented the force of contraction in the human atrial preparations. The inotropic and chronotropic effects of psilocybin and psilocin at 10 µM were smaller than that of 1 µM 5-HT on the left and right atria from 5-HT4-TG, respectively. Psilocybin and psilocin were inactive in WT. In the human atrial preparations, inhibition of the phosphodiesterase III by cilostamide was necessary to unmask the positive inotropic effects of psilocybin or psilocin. The effects of 10 µM psilocybin and psilocin were abrogated by 10 µM tropisetron or by 1 µM GR125487, a more selective 5-HT4 receptor antagonist. In summary, we demonstrated that psilocin and psilocybin act as agonists on cardiac 5-HT4 receptors.

description: Cryogenic mirrors have been introduced to the KAGRA gravitational wave telescope in Japan, and are also planned to be used in next-generation gravitational wave telescopes to further improve their sensitivity. Molecular gases inside vacuum chambers adhere to cold mirror surfaces because they lose their kinetic energy when they hit cryogenic surfaces. Finally, a number of adsorbed molecules form an adlayer, which will grow with time. The growing adlayer functions as an optical coating and changes the properties of the underlying mirror, such as reflectance, transmittance, and absorption, which are carefully chosen to maximize the detector sensitivity. The adlayer possibly affects the gravitational wave detector sensitivity. In order to characterize these changes, a high-finesse Fabry--Perot cavity was introduced to a KAGRA cryostat and the finesse of the cavity was monitored for 35 days under cryogenic conditions. We confirmed that the molecular adlayer was formed on a cold mirror and caused an oscillation in the finesse. The real and imaginary parts of the refractive index of the adlayer were $1.26 \pm 0.073$ and $2.2 \times 10^{-7} \pm 1.3 \times 10^{-7} $, respectively. These are considered to be that of $\mathrm{H_2O}$ molecules. The formation rate of the molecular adlayer was 27 $\pm$ 1.9 $\mathrm{nm/day}$. In this paper, we describe theoretical and experimental studies of the formation of a molecular adlayer on cryogenic mirrors. Furthermore, the effects of a molecular adlayer on the quantum noise and the input heat to the test mass are also discussed.

  Type species.— Artedidraco skottsbergi  (Lönnberg, 1905: 48–49; Fig. 1).
 Definition.— The least inclusive clade that includes Neodraco skottsbergi (Lönnberg, 1905) and Neodraco loennbergi (Roule, 1913). The reference phylogeny is one inferred from the min84 dataset (including DNA sequences of 64,980 ddRAD loci) presented in Figure 2.
 Diagnosis.— First dorsal fin with two to three spines, second dorsal fin with 24 to 28 rays, anal fin with 14 to 17 rays, and pectoral fin with 17 to 21 rays. The upper lateral line has 2 to 9 anterior tubular scales and 1 to 16 posterior disc-shaped scales. Number of vertebrae ranges between 36 and 40. In the caudal skeleton, the parhypural and lower hypural plate are fused with the urostyle (Eakin, 1981). The depth of the head is similar to the body depth to the caudal peduncle. The diameter of the orbit exceeds the length of the snout. The interorbital width is narrow, ranging 13 to 24 times smaller than the head length. The mental barbel is short, ranging between 3.8 to 11.0 times smaller than the head length. There are 6 to 8 dark patches of pigment at the bases of the two dorsal fins that form saddles when viewed from above (Eakin, 1990).
  Comparisons.— Neodraco  is distinguished from species of Artedidraco in having 2 to 9 tubular scales in the upper
 lateral line (more than 6 in the latter), with the tubular scale row not extending beyond the first ray of the second dorsal fin (upper lateral line extends well under the dorsal fin in Artedidraco), 17 or 18 gill rakers on the first gill arch (13 to 16 in Artedidraco), and two to three spines in the first dorsal fin (three to five in Artedidraco; Eakin, 1981, 1990; Eakin et al., 2015). Neodraco differs from Dolloidraco longedorsalis in having fewer than 8 tubular scales in the upper lateral line and the first dorsal fin is positioned above the base of the pectoral fin versus 8 to 18 tubular upper lateral-line scales and the placement of the first dorsal fin above the operculum in D. longedorsalis (Norman, 1938; Eakin, 1990). Neodraco is distinguished from Histiodraco velifer and species of Pogonophryne by the absence of post-temporal ridges (Norman, 1938; Eakin, 1990).
 Etymology.— From the Ancient Greek words me ´oç (neos) meaning new and dqajxm ´(dracon) meaning dragon. The name Neodraco highlights that this is a newly-described lineage of Artedidraconinae identified through the application of molecular phylogenetics (Derome et al., 2002; Lecointre et al., 2011; Near et al., 2012, 2018).

description: We report staggered vorticity correlations of current in the d-wave variational wave function for the lightly-doped t-J model. Such correlations are explained from the SU(2) symmetry relating d-wave and staggered-flux mean-field phases. The correlation functions computed by the variational Monte Carlo method suggest that pairs are formed of holes circulating in opposite directions.

Symmetry-preserving finite-difference discretizations of arbitrary order on structured curvilinear staggered grids

Publisher: name: arXiv

Subjects: subject: Numerical Analysis (math.NA)

description: Symmetry-preserving (mimetic) discretization aims to preserve certain properties of a continuous differential operator in its discrete counterpart. For these discretizations, stability and (discrete) conservation of mass, momentum and energy are proven in the same way as for the original continuous model. This paper presents a new finite-difference symmetry-preserving space discretization. Boundary conditions and time integration are not addressed. The novelty is that it combines arbitrary order of convergence, orthogonal and non-orthogonal structured curvilinear staggered meshes, and the applicability to a wide variety of continuous operators, involving chain rules and nonlinear advection, as illustrated by the shallow-water equations. Experiments show exact conservation and convergence corresponding to expected order.

Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: Within the intermediate-coupling theory, the quasiparticle weight $Z$ of one hole injected in the undoped antiferromagnetic ground state is studied. We find that, for the hole located at the quasiparticle band minimun with momentum ${\bf k}_0 = (\pm \fracπ{2}, \pm \fracπ{2})$, $Z$ is finite. By comparing the results obtained by the self-consistent Born approximation, we show that the intermediate-coupling theory for $Z$ is appropriate only when $J/t \stackrel{>}{\sim} 1.6$. Finally, the reason why this approach fails in the small-$J$ case will also be clarified.

Measurement of associated production of a W boson and a charm quark in proton-proton collisions at $\sqrt{s} =$ 13 TeV
Creators: name: CMS Collaboration
Publisher: name: arXiv
Year: 2018
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: Measurements are presented of associated production of a W boson and a charm quark (W+c) in proton-proton collisions at a center-of-mass energy of 13 TeV. The data correspond to an integrated luminosity of 35.7 fb$^{-1}$ collected by the CMS experiment at the CERN LHC. The W bosons are identified by their decay into a muon and a neutrino. The charm quarks are tagged via the full reconstruction of D$^*$(2010)$^\pm$ mesons that decay via D$^*$(2010)$^\pm \to$ D$^0$ + $π^\pm \to$ K$^{\mp}$ + $π^\pm$ + $π^\pm$. A cross section is measured in the fiducial region defined by the muon transverse momentum $p_{T}^μ >$ 26 GeV, muon pseudorapidity $|η^μ| $ 5 GeV. The inclusive cross section for this kinematic range is $σ$(W+c) = 1026 $\pm$ 31 (stat) $\substack{+76\\-72}$ (syst) pb. The cross section is also measured differentially as a function of the pseudorapidity of the muon from the W boson decay. These measurements are compared with theoretical predictions and are used to probe the strange quark content of the proton.

description: For a function $φ$ in $L^2(0,1)$, extended to the whole real line as an odd periodic function of period 2, we ask when the collection of dilates $φ(nx)$, $n=1,2,3,\ldots$, constitutes a Riesz basis or a complete sequence in $L^2(0,1)$. The problem translates into a question concerning multipliers and cyclic vectors in the Hilbert space $\cal H$ of Dirichlet series $f(s)=\sum_n a_nn^{-s}$, where the coefficients $a_n$ are square summable. It proves useful to model $\cal H$ as the $H^2$ space of the infinite-dimensional polydisk, or, which is the same, the $H^2$ space of the character space, where a character is a multiplicative homomorphism from the positive integers to the unit circle. For given $f$ in $\cal H$ and characters $χ$, $f_χ(s)=\sum_na_nχ(n)n^{-s}$ is a vertical limit function of $f$. We study certain probabilistic properties of these vertical limit functions.

Photoionization calculations of the radiation force due to spectral lines in AGNs

description: One of the main mechanisms that could drive mass outflows in AGNs is radiation pressure due to spectral lines. Although straightforward to understand, the actual magnitude of the radiation force is challenging to compute because the force depends on the physical conditions in the gas, and the strength, spectral energy distribution (SED), and geometry of the radiation field. We present results from our photoionization and radiation transfer calculations of the force multiplier, $M(ξ,t)$, using the same radiation field to compute the gas photoionization and thermal balance. We assume low gas density ($n = 10^4~\rm{cm^{-3}}$) and column density ($N \leq 10^{17}~\rm{ cm^{-2}}$), a Boltzmann distribution for the level populations, and the Sobolev approximation. Here, we describe results for two SEDs corresponding to an unobscured and obscured AGN in NGC 5548. Our main results are the following: 1) although $M(ξ,t)$ starts to decrease with $ξ$ for $ξ\gtrsim 1$ as shown by others, this decrease in our calculations is relatively gradual and could be non-monotonic as $M(ξ,t)$ can increase by a factor of few for $ξ\approx 10-1000$; 2) at these same $ξ$ for which the multiplier is higher than in previous calculations, the gas is thermally unstable by the isobaric criterion; 3) non-LTE effects reduce $M(t,ξ)$ by over two orders of magnitude for $ξ\gtrsim 100$. The dynamical consequence of result (1) is that line driving can be important for $ξ$ as high as $1000$ when the LTE approximation holds, while result (2) provides a natural cloud formation mechanism that may account for the existence of narrow line regions. Result (3) suggests that line driving may not be important for $ξ\gtrsim100$ in tenuous plasma.

description: Both younger and older people have different ways of using and interacting with technical devices (smartphones, laptops and tablets). This study compares both user groups and explores how the technical aids are used in everyday life, what barriers exist and how technical problems are handled. In July and August 2021, 20 semi-structured interviews with young and old people were conducted and analysed using qualitative content analysis. The results show that young people continue to use smartphones more frequently than the older participants and that smartphone functions such as making phone calls are more important for the older participants. Older people prefer a personal support by family members when technical problems occur, whereas the younger study participants favour the more impersonal option via hotlines etc. Finally, it seems to be useful to involve older people in the development process of new technologies, so that the applications can be designed to be as user-friendly as possible.

description: Context. Being the most numerous and oldest stars in the galaxy, M dwarfs are objects of great interest for exoplanet searches. The presence of molecules in their atmosphere complicates our understanding of their atmospheric properties. But great advances have recently been made in the modeling of M dwarfs due to the revision of solar abundances. Aims. We aim to determine stellar parameters of M dwarfs using high resolution spectra (R = 90 000) simultaneously in the visible and the near-infrared. The high resolution spectra and broad wavelength coverage provide an unique opportunity to understand the onset of dust and cloud formation at cool temperatures. Furthermore, this study will help in understanding the physical processes which occur in a cool atmospheres, particularly, the redistribution of energy from the optical to the near-infrared. Methods. The stellar parameters of M dwarfs in our sample have been determined by comparing the high resolution spectra both in the optical and in the near-infrared simultaneously observed by CARMENES with the synthetic spectra obtained from the BT-Settl model atmosphere. The detailed spectral synthesis of these observed spectra both in the optical and in the near-infrared helps to understand the missing continuum opacity. Results. For the first time, we derive fundamental stellar parameters of M dwarfs using the high resolution optical and near-infrared spectra simultaneously. We determine Teff , log g and [M/H] for 292 M dwarfs of spectral type M0 to M9, where the formation of dust and clouds are important. The derived Teff for the sample ranges from 2300 to 4000 K, values of log g ranges from 4.5 geq log g leq 5.5 and the resulting metallicity ranges from -0.5 geq [M/H] leq +0.5. We have also explored the possible differences in Teff , log g and [M/H] by comparing them with other studies of the same sample of M dwarfs.

description: Artedidraconinae A. P. Andriashev 1967: 403   Type species.— Artedidraco mirus Lönnberg (1905: 40–41).
 Definition.— The least inclusive clade that includes Artedidraco mirus Lönnberg (1905: 40–41), Neodraco skottsbergi (Lönnberg, 1905: 48–49), and Dolloidraco longedorsalis Roule (1913: 16), but not Harpagifer bispinis (Forster in Bloch and Schneider, 1801: 45).
 Morphological apomorphies.— (1) Presence of a mental barbel (Eakin, 1981; Balushkin, 2000), (2) five branchiostegal rays (Eakin, 1981; Balushkin, 2000), (3) opercle with a flattened hook (Eakin, 1981), (4) floating pleural ribs starting on 5 th to 8 th vertebrae, or absent (Eakin, 1981; Balushkin, 2000), and (5) four or five hypurals (Eakin, 1981).
 Composition.— There are 12 valid and distinct species of Artedidraconinae with three species of Artedidraco, two species of Neodraco, five species of Pogonophryne, Dolloidraco longedorsalis, and Histiodraco velifer. Eastman and Eakin (2021) list 27 species of Pogonophryne, but analysis of morphology and DNA sequences of ddRAD loci lead to the delimitation of only five described species in the clade (Parker et al., 2021). Based on analyses of morphology and DNA sequences of ddRAD loci presented in this study, we recognized three species of Artedidraco. We treat Artedidraco glareobarbatus (Eastman and Eakin, 1999) as a junior synonym of A. shackletoni (Waite, 1911). Pending additional morphological and molecular analyses, we suggest that the recognition of A. longibarbatus (Eakin et al., 2015) as a distinct species is unwarranted.

Elementary arguments seem to preclude any possibility of observation of ``Hall drag'' (i.e., a non-zero off-diagonal component in $\tensorρ_{21}$). We show that these arguments are specious, and in fact Hall drag can be observed at sufficiently high temperatures when the {\sl intra}layer transport time $τ$ has significant energy-dependence around the Fermi energy $\varepsilon_F$. The ratio of the Hall to longitudinal transresistivities goes as $T^2 B s$, where $T$ is the temperature, $B$ is the magnetic field, and $s = [\partialτ/ \partial\varepsilon] (\varepsilon_F)$.

description: Objectives - The risk of Post-COVID-19 condition (PCC) under hybrid immunity remains unclear. - Methods - Using data from the German National Cohort (NAKO Gesundheitsstudie), we investigated risk factors for self-reported post-infection symptoms (any PCC is defined as having at least one symptom, and high symptom burden PCC as having nine or more symptoms). - Results - Sixty percent of 109,707 participants reported at least one previous SARS-CoV-2 infection; 35% reported having had any symptoms 4-12 months after infection; among them 23% reported nine or more symptoms. Individuals, who did not develop PCC after their first infection, had a strongly reduced risk for PCC after their second infection (50%) and a temporary risk reduction, which waned over 9 months after the preceding infection. The risk of developing PCC strongly depended on the virus variant. Within variants, there was no effect of the number of preceding vaccinations, apart from a strong protection by the fourth vaccination compared to three vaccinations for the Omicron variant (odds ratio = 0.52; 95% confidence interval 0.45-0.61). - Conclusions - Previous infections without PCC and a fourth vaccination were associated with a lower risk of PCC after a new infection, indicating diminished risk under hybrid immunity. The two components of risk reduction after a preceding infection suggest different immunological mechanisms.

description: In the model the entire high-energy part of the amplitude (Regge power dependence from the total energy) comes as consequence of Gribov's diffusion of the constituent quarks in the space of rapidities and impact parameters. Charge exchange of the quarks, which goes at small quark anti-quark invariant masses, is described by low-energy Nambu - Jona-Lasinio model. It is shown that spin structure of the amplitudes and dominating spin-orbit (spin-flip) amplitudes are well described by this model without free parameters.

description: Objective: The course of sedation during drug-induced sleep endoscopy (DISE) depends on the application pattern of the sedative drug. The depth of sedation should imitate light and deep sleep as well. Moreover, there should be as many breathing cycles as possible available for observation during light and deep sedation. The aim of the study was to evaluate different rates of propofol application with respect to the achieved depth and length of the course of sedation. Methods: Sixty-three consecutive patients with obstructive sleep apnea and/or snor- ing undergoing DISE were randomly sedated by propofol perfusion at seven different application patterns: 14, 16, 18, 19, 20, 22 mg/kg/h (0.233, 0.267, 0.3, 0.317, 0.333, 0.367 mg/kg/min) per perfusor and individual bolus application 10 mg each. Sedation depth was monitored by BiSpectral Index™ (BIS). The influence of baseline parame- ters and the courses of sedation were analyzed. Results: The application rate was the only factor that influenced the depth of seda- tion. Basic parameters (gender, age, body mass index, apnea-hypopnea index) had no influence on the depth of sedation. The sedation depth was dependent on the rate of propofol application. Regimes at 14 and 16 mg/kg/h as well as bolus application did not reach BIS levels below 50 representing deep sleep. Propofol doses of more than 20 mg/kg/h led to rapid decreases of sedation levels below deep sleep niveau. Propo- fol rates between 18 and 20 mg/kg/h enable BIS levels below 50 representing deep sleep and providing enough breathing cycles for observation. Conclusion: Lower application rates of propofol provide slower courses of sedation and shallower depths of sedation. A rate of 14 mg/kg/h might be appropriate to reach a sedation plateau at light sleep. A rate of 18 mg/kg/h leads to a sedation, cor- responding to deep sleep. The combination of both rates might be a suitable pattern for performing sedation-controlled DISE.

description: Multi-band quasi-particle calculations based on perturbation theory and dynamical mean field methods show that the creation of a photoemission hole state in Sr$_2$RuO$_4$ is associated with a highly anisotropic self-energy. Since the narrow Ru-derived $d_{xz,yz}$ bands are more strongly distorted by Coulomb correlations than the wide $d_{xy}$ band, charge is partially transferred from $d_{xz,yz}$ to $d_{xy}$, thereby shifting the $d_{xy}$ van Hove singularity close to the Fermi level.

description: It is known that there is a unique concordance class in the free homotopy class of $S^1\times pt \subset S^1 \times S^2$. The constructive proof of this fact is given by the second author. It turns out that all the concordances in this construction are invertible. The knots $K\subset S^{1}\times S^{2}$ with hyperbolic complements and trivial symmetry group are special interest here, because they can be used to generate absolutely exotic compact 4-manifolds by the recipe given by Akbulut and Ruberman. Here we built absolutely exotic manifold pairs by this construction, and show that this construction keeps the Stein property of the $4$-manifolds we start out with. By using this we establish the existence of an absolutely exotic contractible Stein manifold pair, and absolutely exotic homotopy $S^1\times B^3$ Stein manifold pair.

description: We investigate the reactive dissolution process of poly(sulfur nitride) (SN)x in the ionic liquid (IL) 1-ethyl-3-methylimidazolium acetate [EMIm][OAc] in comparison to the process of elemental sulfur in the same IL. It has been known from the literature that during the reaction of S8 with [EMIm][OAc], the respective thione is formed via a radical mechanism. Here, we present new results on the kinetics of the formation of the respective imidazole thione (EMImS) via the hexasulfur dianion [S6]2– and the trisulfur radical anion [S3]•–. We can show that [S6]2– is formed first, which dissociates then to [S3]•–. Also, long-term stable radicals occur, which are necessary side products provided in a reaction scheme. During the reaction of [EMIm][OAc] with (SN)x chains, two further products can be identified, one of which is the corresponding imine. The reactions are followed by time-resolved NMR spectroscopic methods that showed the corresponding product distributions and allowed the assignment of the individual signals. In addition, continuous-wave (CW) EPR and UV/vis spectroscopic measurements show the course of the reactions. Another significant difference in both reactions is the formation of a long-term stable radical in the sulfur–IL system, which remains active over 35 days, while for the (SN)x–IL system, we can determine a radical species only with the spin trap 5,5-dimethyl-1-pyrrolin-N-oxide, which indicates the existence of short-living radicals. Since the molecular dynamics are restricted based on the EPR spectra, these radicals must be large.

description: Diffusion Monte Carlo results for the phonon-roton excitation branch in bulk liquid $^4$He at zero temperature are presented. The sign problem associated to the excited wave function has been dealt both with the fixed-node approximation and the released-node technique. The upper bounds provided by the fixed-node approximation are shown to become exact when using the released-node method. An excellent agreement with experimental data is achieved both at the equilibrium and near the freezing densities.

description: Multiple systems estimation strategies have recently been applied to quantify hard-to-reach populations, particularly when estimating the number of victims of human trafficking and modern slavery. In such contexts, it is not uncommon to see sparse or even no overlap between some of the lists on which the estimates are based. These create difficulties in model fitting and selection, and we develop inference procedures to address these challenges. The approach is based on Poisson log-linear regression modeling. Issues investigated in detail include taking proper account of data sparsity in the estimation procedure, as well as the existence and identifiability of maximum likelihood estimates. A stepwise method for choosing the most suitable parameters is developed, together with a bootstrap approach to finding confidence intervals for the total population size. We apply the strategy to two empirical data sets of trafficking in US regions, and find that the approach results in stable, reasonable estimates. An accompanying R software implementation has been made publicly available.

description: The visible and dark sectors of particle physics can be connected via kinetic mixing between ordinary and hidden photons. If the latter is light its production in high energy collisions of ordinary particles proceeds via oscillations with ordinary photons similarly to the neutrino processes. Generically, the experiments are insensitive to mass of the hidden vector, if it is lighter than 1\,MeV, and it does not decay into $e^+e^-$-pair. Still, one can use the missing energy and scattering off the detector material as signatures to search for the light vectors. Presence of media suppresses production of the light vectors making the experiments insensitive to the entire model. We present analytic formulas for the light hidden photon production, propagation and detection valid for searches at colliders and beam-target experiments and apply them to estimate the impact on the sensitivities of a set of experiments --- NA64, FASER, MATHUSLA, SHiP, T2K, DUNE, NA62 --- in a zero-background case.

Noise in gene expression may be a choice of cellular system

description: Gene expression and its regulation is a nonequilibrium stochastic process. Different molecules are involved in several biochemical steps in this process with low copies. It is observed that the stochasticity in biochemical processes is mainly due to the low copy number of the molecules present in the system. Several studies also show that the nonequilibrium biochemical processes require energy cost. But cellular system has developed itself through natural evolution by minimizing energy cost for optimum output. Here we study the role of stochasticity qualitatively in a network of two genes using stochastic simulation method and approximately measure the energy consumption for the gene expression process. We find that the noise in gene expression process reduces the energy cost of protein synthesis. Therefore, we argued that the stochasticity in gene expression may be a choice of cellular system for protein synthesis with minimum energy cost.
