description: When applying the barycentric correction to a precise radial velocity measurement, it is common practice to calculate its value only at the photon-weighted midpoint time of the observation instead of integrating over the entire exposure. However, since the barycentric correction does not change linearly with time, this leads to systematic errors in the derived radial velocities. The typical magnitude of this second-order effect is of order 10 cm s$^{-1}$, but it depends on several parameters, e.g. the latitude of the observatory, the position of the target on the sky, and the exposure time. We show that there are realistic observing scenarios, where the errors can amount to more than 1 ms$^{-1}$. We therefore recommend that instruments operating in this regime always record and store the exposure meter flux curve (or a similar measure) to be used as photon-weights for the barycentric correction. In existing data, if the flux curve is no longer available, we argue that second-order errors in the barycentric correction can be mitigated by adding a correction term assuming constant flux.

description: In this article we consider the numerical approximation of the convection-diffusion-reaction equation. One of the main challenges of designing a numerical method for this problem is that boundary layers occurring in the convection-dominated case can lead to non-physical oscillations in the numerical approximation, often referred to as Gibbs phenomena. The idea of this article is to consider the approximation problem as a residual minimization in dual norms in Lq-type Sobolev spaces, with 1 < q < $\infty$. We then apply a non-standard, non-linear PetrovGalerkin discretization, that is applicable to reflexive Banach spaces such that the space itself and its dual are strictly convex. Similar to discontinuous Petrov-Galerkin methods, this method is based on minimizing the residual in a dual norm. Replacing the intractable dual norm by a suitable discrete dual norm gives rise to a non-linear inexact mixed method. This generalizes the Petrov-Galerkin framework developed in the context of discontinuous Petrov-Galerkin methods to more general Banach spaces. For the convection-diffusion-reaction equation, this yields a generalization of a similar approach from the L2-setting to the Lq-setting. A key advantage of considering a more general Banach space setting is that, in certain cases, the oscillations in the numerical approximation vanish as q tends to 1, as we will demonstrate using a few simple numerical examples.

description: The objective of this study was to analyse the technical efficiency (TE) of the milk production on totally 83 cattle herds (database of APRC Nitra) in the period 2006-2010 and to synthesise impact of the main inputs (costs) on the TE value. A nonparametric approach Data Envelopment Analysis with the input-oriented variable return to scale model was used to evaluate the TE value. Average value of TE in the analysed period was 0.96, i.e. evaluated herds reached 96% of technical efficiency in milk production on average. For these, reduction of inputs by 4% is recommended to reach the efficiency at the given level of milk yield. Value of individual inputs: total feed costs, material costs, labour costs, repair and service, depreciation, other direct costs and overhead costs, should be reduced by 3.7, 10.0, 3.3, 15.8, 2.1, 2.9 and 8.5% respectively, while maintaining the same level of output. It is possible to state that the analysed farms are inefficient in utilization of inputs for the given level of output. The TE value was statistically significantly influenced by the feed costs only. The negative influence of this factor indicates inefficient utilization of feeds (balance of feeding ration, losses of storage, reciprocal substitution of feeds) or inefficient utilization of its production potential in relation to the given output level.

description: We introduce a generalised form of an emergent dark energy model with one degree of freedom for the dark energy sector that has the flexibility to include both $Λ$CDM model as well as the Phenomenologically Emergent Dark Energy (PEDE) model proposed by Li & Shafieloo (2019) as two of its special limits. The free parameter for the dark energy sector, namely $Δ$, has the value of $0$ for the case of the $Λ$ and $1$ for the case of PEDE. Fitting the introduced parametric form to Planck CMB data and most recent $H_0$ results from local observations of Cepheids and Supernovae, we show that the $Δ=0$ associated with the $Λ$CDM model would fall out of 4$σ$ confidence limits of the derived posterior of the $Δ$ parameter. Moreover, $H_0$ tensions will be alleviated with emergent dark energy model and this model can satisfy the combination of Planck CMB data and local $H_0$ observations with $Δ{\rm{DIC}}\,=\,-2.88$ compared with $\LCDM$ model.

description: The use of the AdS/CFT correspondence to arrive at quiver gauge field theories is dicussed, focusing on the orbifolded case without supersymmetry. An abelian orbifold with the finite group $Z_{p}$ can give rise to a $G = SU(N)^p$ gauge group with chiral fermions and complex scalars in different bi-fundamental representations of $G$. The precision measurements at the $Z$ resonance suggest the values $p = 12$ and $N = 3$, and a unifications scale $M_U \sim 4$ TeV.The robustness and predictivity of such grand unification is discussed.

description: The emission in the hyperfine structure 21 cm line of atomic hydrogen arising in the halos with masses $\sim10^6-10^{10}$ M$_\odot$ from the Dark Ages in the models with Warm Dark Matter (WDM) is analysed. The halos are assumed to be formed from Gaussian density peaks of cosmological density perturbations at $10\lesssim z\lesssim50$. Semi-analytical modelling of the formation of individual spherical halos in multi-component models shows that gas in them has the kinetic temperature in the range of $60-800$ K under adiabatic compression of the collapsing halo, and the temperature of each halo depends on the time of virialization. It is shown that inelastic collisions between neutral hydrogen atoms are the dominant excitation mechanism for hyperfine structure levels, which pulls the spin temperature closer to the kinetic temperature. The brightness temperature of individual halos is in the range of 1-10 K, depending on the mass of the halo and its virialization redshift, and increasing as these two increase. The apparent angular radii of such halos are in the range 0.06-1.2 arcseconds, their surface number density decreasing exponentially from a few per arcmin$^2$ for the lowest mass and redshift to nearly zero for higher values. Assuming a 1 MHz observation bandwidth the surface number density of the halo at various redshifts is evaluated as well as beam-averaged differential antenna temperatures and fluxes of hydrogen emission from halos of different masses. The beam-averaged signal strongly depends on the cut-off scale in the mass function of dark ages halos that may be caused by free-streaming of WDM particles. The finding is compared with the upper limits on the amplitude of the power spectrum of the hydrogen 21-cm line fluctuations derived from the recent observation data obtained with MWA and LOFAR.

description: We report on an extensive study of the influence of spin anisotropy on spin glass aging dynamics. New temperature cycle experiments allow us to compare quantitatively the memory effect in four Heisenberg spin glasses with various degrees of random anisotropy and one Ising spin glass. The sharpness of the memory effect appears to decrease continuously with the spin anisotropy. Besides, the spin glass coherence length is determined by magnetic field change experiments for the first time in the Ising sample. For three representative samples, from Heisenberg to Ising spin glasses, we can consistently account for both sets of experiments (temperature cycle and magnetic field change) using a single expression for the growth of the coherence length with time.

description: Employee performance evaluation systems, which are well designed and properly used, are essential for the effective functioning of the organization. Due to some disadvantages of traditional methods, there is a need to develop new evaluation procedures. The main contribution of this paper is to apply a multidimensional approach, represented by the method of Data Envelopment Analysis (DEA) to measure the performance and efficiency of employees. This approach overcomes several weaknesses of traditional systems of the employees’ performance evaluation and provides a comprehensive indicator of the performance of individual employees, their technical efficiency score. The input variables of the used model were the motivational factors (salary, working conditions and benefits); the output was the indirectly assessed performance through work motivation, job satisfaction and organizational commitment. Furthermore, we applied the nonparametric methods for compliance testing of mean values to validate the stated hypotheses. In a baking company using the DEA method, we identified 12 efficient employees and 48 employees who need to improve their outputs to achieve their maximum efficiency.

description: In this paper we present a theoretical analysis of the effect of anomalies of the Fermi surface (FS) curvature on oscillations in the electron density of states (DOS) in strong magnetic fields. It is shown that the oscillations could be significantly strengthened when the FS curvature turns zero in the vicinities of some extremal cross sections, and they could be weakened when the curvature takes on extremely large values or diverges there. This leads to a characteristic dependence of the oscillations magnitude on the direction of the magnetic field which is studied. The results of these general studies are employed to analyze the effects of the FS curvature anomalies on the quantum oscillations in the velocity of sound waves travelling in metals.

description: Evidence suggests that brain network dynamics is a key determinant of brain function and dysfunction. Here we propose a new framework to assess the dynamics of brain networks based on recurrence analysis. Our framework uses recurrence plots and recurrence quantification analysis to characterize dynamic networks. For resting-state magnetoencephalographic dynamic functional networks (dFNs), we have found that functional networks recur more quickly in people with epilepsy than healthy controls. This suggests that recurrence of dFNs may be used as a biomarker of epilepsy. For stereo electroencephalography data, we have found that dFNs involved in epileptic seizures emerge before seizure onset, and recurrence analysis allows us to detect seizures. We further observe distinct dFNs before and after seizures, which may inform neurostimulation strategies to prevent seizures. Our framework can also be used for understanding dFNs in healthy brain function and in other neurological disorders besides epilepsy.

description: The Visegrad Countries (V4) accession to the European Union in 2004 caused several changes in the field of agriculture. The aim of this paper is to analyse impact of the EU enlargement on V4 agri-food trade, especially considering revealed comparative advantages. Results suggest that intensity of the V4 agri-food trade has increased significantly after the enlargement. There was deterioration in the V4 agri-food trade balance with the EU15 in most cases. All analysed countries experienced a decrease in their comparative advantage, though it still remained on acceptable level in most cases. We observed weakening comparative advantage stability, underpinned by convergence of revealed comparative advantage pattern. By estimating the survival function, we found that the enlargement changed survival time of the V4 agri-food trade. Revealed comparative advantage is shown not to be persistent.

description: We present a deep, new 1200 micron survey of the ELAIS N2 and Lockman Hole fields using the Max Planck Millimeter Bolometer array (MAMBO). The areas surveyed are 160 arcmin^2 in ELAIS N2 and 197 arcmin^2 in the Lockman Hole, covering the entire SCUBA `8 mJy Survey'. In total, 27 (44) sources have been detected at a significance >=4.0sigma (>=3.5sigma). We present the 1200 micron number counts and find evidence of a fall at bright flux levels. Employing parametric models for the evolution of the local 60 micron IRAS luminosity function (LF), we are able to account simultaneously for the 1200 and 850 micron counts, suggesting that the MAMBO and SCUBA sources trace the same underlying population of high-redshift, dust-enshrouded galaxies. From a nearest-neighbour clustering analysis we find tentative evidence that the most significant MAMBO sources come in pairs, typically separated by ~23". Our MAMBO observations unambiguously confirm around half of the SCUBA sources. In a robust sub-sample of 13 SMGs detected by both MAMBO and SCUBA at a significance >=3.5sigma, only one has no radio counterpart. Furthermore, the distribution of 850/1200 micron flux density ratios for this sub-sample is consistent with the spectroscopic redshift distribution of radio-detected SMGs (Chapman et al. 2003). Finally, we have searched for evidence of a high-redshift tail of SMGs amongst the 18 MAMBO sources which are not detected by SCUBA. While we cannot rule out that some of them are SCUBA drop-outs at z >> 3, their overall 850-to-1200 micron flux distribution is statistically indistinguishable from that of the 13 SMGS which were robustly identified by both MAMBO and SCUBA.

description: A beam codebook of 5G millimeter wave (mmWave) for data communication consists of multiple high-peak-gain beams to compensate the high pathloss at the mmWave bands. These beams also have to point to different angular directions, such that by performing beam searching over the codebook, a good mmWave signal coverage over the full sphere around the terminal (spherical coverage) can be achieved. A model-based beam codebook design that assumes ideal omni-directional antenna pattern, and neglects the impact of terminal housing around the antenna, does not work well because the radiation pattern of a practical mmWave antenna combined with the impact of terminal housing is highly irregular. In this paper, we propose a novel and efficient data-driven method to generate a beam codebook to boost the spherical coverage of mmWave terminals. The method takes as inputs the measured or simulated electric field response data of each antenna and provides the codebook according to the requirements on the codebook size, spherical coverage, etc. The method can be applied in a straightforward manner to different antenna type, antenna array configuration, placement and terminal housing design. Our simulation results show that the proposed method generates a codebook better than the benchmark and 802.15.3c codebooks in terms of the spherical coverage.

description: This study undertakes an analysis of the conceptualization of gender identity in neuroscientific studies of (trans)gender identity that contrast the brains of cisgender and transgender participants. The analysis focuses on instances of epistemic injustice that combine scientific deficiencies and the exclusion of relevant bodies of knowledge. The results of a content analysis show how the ignoring of biosocial, developmental, mosaicist, contextualist, and depathologizing approaches leads to internal conceptual inconsistencies, hermeneutical deficiencies and the upholding of questionable paradigms in the research field. Interviews with researchers involved in these brain studies reveal targeted and diffuse forms of testimonial injustice against alternative approaches, promoted by the hierarchical arrangements of research teams in combination with the careerist and economic logic of research. The analysis points to the exclusion of critical epistemologies of science and the historical oppression of trans people as epistemic agents as the underlying hermeneutical deficiencies.

description: A time-dependent Kohn-Sham (KS)-like equation for N bosons in a trap is generalized for the case of inelastic collisions. We derive adiabatic equations which are used to calculate the nonlinear dynamics of the Bose-Einstein condensate (BEC) and non-mean field corrections due to the three-body recombination. We find that the calculated corrections are about 13 times larger for 3D trapped dilute bose gases and about 7 times larger for 1D trapped weakly interacting bose gases when compared with the corresponding corrections for the ground state energy and for the collective frequencies.

description: Coronavirus 2019 (COVID-19) poses a serious threat to human health. In China, traditional Chinese medicine (TCM), mainly based on the Maxing Shigan decoction (MXSGD), is used in conjunction with western medicine to treat COVID-19. We conducted a network meta-analysis to investigate whether MXSGD-related TCM combined with western medicine is more effective in treating COVID-19 compared to western medicine alone. Additionally, using network pharmacology, cross-docking, and molecular dynamics (MD) simulation to explore the potential active compounds and possible targets underlying the therapeutic effects of MXSGD-related TCM. MXSGD-related TCM combined with western medicine was better for treating COVID-19 compared to western medicine alone. Network pharmacological analysis identified 43 shared ingredients in the MXSGD-related TCM prescriptions and 599 common target genes. Cross-docking of the 43 compounds with 154 proteins that matched these genes led to the identification of 60 proteins. Pathway profiling revealed that the active ingredients participated in multiple signaling pathways that contribute to their efficacy. Molecular docking and MD simulation demonstrated that MOL007214, the most promising molecule, could stably bind to the active site of SARS-CoV-2 3CLpro. This study demonstrates the important role of MXSGD-related TCM in the treatment of COVID-19.

description: The paper provides descriptive analyses of the EU New Member States agriculture over the period from 2000 to 2011. In 2004 and 2007, twelve New Member States (NMS) joined the European Union, which has offered several possibilities and challenges to the newcomers. The aim of the paper is to discuss development of agriculture in the EU New Member States. We evaluate the status of this sector as well as identify factors lying behind the NMS performances. The EU accession has had an overall positive impact on the NMS agriculture, although the NMS capitalised their possibilities in a different manner, due to initial conditions and pre- and post-accession policies.

description: The search for universal laws that help establish a relationship between dynamics and computation is driven by recent expansionist initiatives in biologically inspired computing. A general setting to understand both such dynamics and computation is a driven dynamical system that responds to a temporal input. Surprisingly, we find memory-loss a feature of driven systems to forget their internal states helps provide unambiguous answers to the following fundamental stability questions that have been unanswered for decades: what is necessary and sufficient so that slightly different inputs still lead to mostly similar responses? How does changing the driven system's parameters affect stability? What is the mathematical definition of the edge-of-criticality? We anticipate our results to be timely in understanding and designing biologically inspired computers that are entering an era of dedicated hardware implementations for neuromorphic computing and state-of-the-art reservoir computing applications.

State of a particle pair produced by the Schwinger effect is not necessarily a maximally entangled Bell state

description: We analyze the spins of a Schwinger particle pair in a spatially uniform but time dependent electric field. The particle pair's spins are in the maximally entangled Bell state only if the particles' momenta are parallel to the electric field. However if transverse momentum is present, the spins are not in the maximally entangled Bell state. The reason is that the pair is created by the external field, which also carries angular momentum, and the particle pair can take away some of this external angular momentum.

description: We suggest the possibility that in ADD type brane-world scenarios, the higher KK excitations of the graviton may decay to lower ones owing to a breakdown of the conservation of extra dimensional ``momenta'' and study its implications for astrophysics and cosmology. We give an explicit realization of this idea with a bulk scalar field $Φ$, whose nonzero KK modes acquire vacuum expectation values. This scenario helps to avoid constraints on large extra dimensions that come from gamma ray flux bounds in the direction of nearby supernovae as well as those coming from diffuse cosmological gamma ray background. It also relaxes the very stringent limits on reheat temperature of the universe in ADD models.

description: Polymoria halyomorphae Risbec, 1951
 Polymoria halyomorphae Risbec, 1951a: 243-245. Original description, ♀, Senegal, Bambey; 1950a: 404 (nomen nudum); 1960a: 656 (catalogued). — Herting 1971: 88 (catalogued).
 Calosota halyomorphae – Hedqvist 1970: 420-423, 439 (lectotype designation, change of combination, redescribed, figured, keyed). — Gibson 1989: 63 (catalogued).
 CURRENT TAXONOMIC STATUS. — Calosota halyomorphae (Risbec,1951).
 TYPE MATERIAL. — General collection. Lectotype ♀: “ Polymoria / halyo [mo] rphae Risbec/ ex ω. Halyomorpha / annulicornis [label detached from a slide, in Risbec’s handwriting]; Lectotypus ♀ / Polymoria / halyomorphae / Risb./ K-J Hedqvist det. 1965; Calosota / halyomorphae ”.
REMARKS
 This species was described based on at least two specimens: “Longueur du corps:3,2 et 2,85 mm”. Hedqvist (1970) reports seeing two specimens on one slide (slide MNHN.14.68 is missing), but there is only one remounted female in the general collection (the lectotype). In BMNH there is a specimen without locality data, originating from Hedqvist’s personal collection but with an identification label by Hedqvist: “ Calosota / halyomorphae / (Risb./ ♀ / K-J Hedqvist det. 69”. This is a paralectotype of Polymoria halyomorphae since Hedqvist (1970), when redescribing the species, mentions only the two Risbec’s syntypes, without any other additional specimens.

description: Paralelo aos processos de integração econômica e expansão comercial tem-se observado que, vários países, muitos deles parceiros comerciais, vem se tornando crescentemente semelhantes em seus níveis de tecnologia e na disponibilidade de recursos, o que vem proporcionando o aumento nas trocas em duas vias dentro de uma mesma indústria, que configura no chamado comércio intra-indústria. Diante desse contexto, o presente trabalho buscar avaliar em que medida o Mercosul tem apresentado efeitos sobre o comércio regional. Para tanto foram utilizados, o Índice de Intensidade de Comércio (IIC), o Índice de Orientação Regional (IOR) e o Índice Grubel-Lloyd (GL) de comércio intraindústria. O índice de intensidade de comércio indicou que as trocas comerciais entre Brasil e os países do Bloco aumentaram com a formação do Mercosul. O índice de orientação regional, apresentou valores crescentes e sempre superiores a 1, indicando tendência favorável a expansão comercial dentro do bloco. Com relação ao índice GL, verificou-se aumento no valor dos índices de comércio intra-indústria em várias seções e também no número de seções com índices GL acima de 0,50 Tais resultados indicaram diferenças produtivas condizentes com o maior relacionamento intra-setorial multilateral, entre os países membros do Mercosul. Indicaram, também, o maior potencial competitivo da indústria brasileira nas seções que envolvem atividades industriais mais complexas.

description: We construct chiral N=(1,0) self-dual supergravity in Euclidean eight-dimensions with reduced holonomy Spin(7), including all the higher-order interactions in a closed form. We first establish the non-chiral N=(1,1) superspace supergravity in eight-dimensions with SO(8) holonomy without self-duality, as the foundation of the formulation. In order to make the whole computation simple, and the generalized self-duality compatible with supersymmetry, we adopt a particular set of superspace constraints similar to the one originally developed in ten-dimensional superspace. The intrinsic properties of octonionic structure constants make local supersymmetry, generalized self-duality condition, and reduced holonomy Spin(7) all consistent with each other.

description: Motivated by results for the propagation of active-passive interfaces of bacterial Serratia marcescens swarms [Nat. Comm., 9, 5373 (2018)] we use a hydrodynamic multiphase model to investigate the propagation of interfaces of active nematics on substrates. We characterize the active nematic phase of the model and discuss its description of the statistical dynamics of the swarms. We show that the velocicity correlation functions and the energy spectrum of the active turbulent phase of the model scale with the active length, for a range of activities. In addition, the energy spectrum exhibits two power-law regimes with exponents close to those reported for other models and bacterial swarms. Although the exponent of the rising branch of the spectrum (small wavevector) appears to be independent of the activity, the exponent of the decay changes with activity systematically, albeit slowly. We characterize also the propagation of circular and flat active-passive interfaces. We find that the closing time of the circular passive domain decays quadratically with the activity and that the structure factor of the flat interface is similar to that reported for swarms, with an activity dependent exponent. Finally, the effect of the substrate friction was investigated. We found an activity dependent threshold, above which the turbulent active nematic forms isolated islands that shrink until the system becomes isotropic and below which the active nematic expands, with a well defined propagating interface. The interface may be stopped by a fricion gradient.
