description: The study investigates the perceptions of the effects and impacts on the performance of agricultural and livestock farms based on the view of obtaining dynamic capabilities by the adoption of enterprise resource planning (ERP) technology. The dimensions for measuring farmers’ perceptions of ERP adoption were technological, organizational and environmental and their diffusion and the impacts measured on dynamic capabilities were on internal operations, costs, sales and natural resources. A total of 502 farmers directly involved in managing the production, located in the main agricultural areas of Brazil were interviewed. The results indicated that the perception of obtaining dynamic capabilities in the farms by adopting the ERP was significant, but with lower levels in costs and natural resources. The influence of farm size on ERP adoption and its perception on farm performance was not significant. The proposed model proved to be adequate and can be validated and compared with other producing regions.

description: The problem faced in this paper concerns the recognition of simple and complex geometric primitives in point clouds resulting from scans of mechanical CAD objects. A large number of points, the presence of noise, outliers, missing or redundant parts and uneven distribution are the main problems to be addressed to meet this need. In this article we propose a solution, based on the Hough transform, that can recognize simple and complex geometric primitives and is robust to noise, outliers, and missing parts. Additionally, we can extract a series of geometric descriptors that uniquely characterize a primitive and, based on them, aggregate the output into maximal or compound primitives, thus reducing oversegmentation. The results presented in the paper demonstrate the robustness of the method and its competitiveness with respect to other solutions proposed in the literature.

description: When studying thermalization of quantum systems, it is typical to ask whether a system interacting with an environment will evolve towards a local thermal state. Here, we show that a more general and relevant question is "when does a system thermalize relative to a particular reference?" By relative thermalization we mean that, as well as being in a local thermal state, the system is uncorrelated with the reference. We argue that this is necessary in order to apply standard statistical mechanics to the study of the interaction between a thermalized system and a reference. We then derive a condition for relative thermalization of quantum systems interacting with an arbitrary environment. This condition has two components: the first is state-independent, reflecting the structure of invariant subspaces, like energy shells, and the relative sizes of system and environment; the second depends on the initial correlations between reference, system and environment, measured in terms of conditional entropies. Intuitively, a small system interacting with a large environment is likely to thermalize relative to a reference, but only if, initially, the reference was not highly correlated with the system and environment. Our statement makes this intuition precise, and we show that in many natural settings this thermalization condition is approximately tight. Established results on thermalization, which usually ignore the reference, follow as special cases of our statements.

description: We demonstrate that edge currents develop in active chiral matter -- composed of spinning disk-shaped grains with chirally arranged tilted legs confined in a circular vibrating chamber -- due to boundary shielding over a wide range of densities corresponding to a gas, fluid, and crystal. The edge currents are then shown to increasingly drive circulating bulk flows with area fraction $ϕ$ due to increasing spin-coupling between neighbors mediated by frictional contacts, as percolating clusters develop. Edge currents are observed even in the dilute limit. While, at low $ϕ$, the average flux vanishes except within a distance of a single particle diameter of the boundary, the penetration depth grows with increasing $ϕ$ till a solid body rotation is achieved corresponding to the highest packing, where the particles are fully caged with hexagonal order and spin in phase with the entire packing. A coarse-grained model, based on the increased collisional interlocking of the particles with $ϕ$ and the emergence of order, captures the observed flow fields.

description: The treatment of the quark mass plays an important role when it comes to increasing the precision of the predictions of the heavy quark expansion for inclusive heavy hadron decays. Various short-distance mass schemes have been invented to minimize the uncertainties induced by the quark mass, which needs to be extracted from other, independent observables. We suggest to replace the quark mass directly by an observable such as e.g. the inverse moments of the cross section for $e^+ e^- \to $ hadrons. We investigate this alternative strategy and study its impact on the perturbative series.

Ion-neutral friction and accretion-driven turbulence in self-gravitating filaments

description: Recent Herschel observations have confirmed that filaments are ubiquitous in molecular clouds and suggest that irrespectively of the column density, there is a characteristic width of about 0.1 pc whose physical origin remains unclear. We develop an analytical model that can be applied to self-gravitating accreting filaments. It is based on one hand on the virial equilibrium of the central part of the filament and on the other hand on energy balance between the turbulence driven by accretion onto the filament and dissipation. We consider two dissipation mechanisms the turbulent cascade and the ion-neutral friction. Our model predicts that the width of the filament inner part is almost independent of the column density and leads to values comparable to what is inferred observationally if dissipation is due to ion-neutral friction. On the contrary turbulent dissipation leads to a structure that is bigger and depends significantly on the column density. Our model provides a reasonable physical explanation which could explain the observed filament width when they are self-gravitating. It predicts the correct order or magnitude though hampered by some uncertainties.

description: Ferromagnetism and its evolution in the orthorhombic perovskite system Sr1-xCaxRuO3 have been widely believed to correlate with the structural distortion. The recent development of high-pressure synthesis of the Ba substituted Sr1-yBayRuO3 makes it possible to study ferromagnetism over a broader phase diagram, which includes new orthorhombic Imma and the cubic phases. However, the chemical substitutions introduce the A-site disorder effect on Tc, which complicates determination of the relationship between ferromagnetism and the structural distortion. By clarifying the site disorder effect on Tc in several new series of ruthenates in which the average bond length keeps the same, but the bond-length variance varies, we are able to demonstrate a parabolic curve of Tc versus mean bond length . A much higher Tc ~ 177 K than that found in orthorhombic SrRuO3 can be obtained from the curve at a bond length which makes the geometric factor t = /(sqrt(2)) = 1. This new result reveals not only that the ferromagnetism in the ruthenates is extremely sensitive to the lattice strain, but also that it has an important implication for exploring the structure-property relationship in a broad range of oxides with perovskite or perovskite-related structure.

description: Complex systems are characterized by strong coupling between different microscopic degrees of freedom. Photoexcitation of such materials can drive them into new transient and long-lived hidden phases that may not have any counterparts in equilibrium. By exploiting femtosecond time- and angle-resolved photoemission spectroscopy, we probe the photoinduced transient phase and the recovery dynamics of the ground state in a complex material: the charge density wave (CDW)-Mott insulator 1$T$-TaS$_2$. We reveal striking similarities between the band structures of the transient phase and the (equilibrium) structurally undistorted metallic phase, with evidence for the coexistence of the low-temperature Mott insulating phase and high-temperature metallic phase. Following the transient phase, we find that the restoration of the Mott and CDW order begins around the same time. This highlights that the Mott transition is tied to the CDW structural distortion, although earlier studies have shown that the collapse of Mott and CDW phases are decoupled from each other. Interestingly, as the suppressed order starts to recover, a long-lived metastable phase emerges before the material recovers to the ground state. Our results demonstrate that it is the CDW lattice order that drives the material into this metastable phase, which is indeed a commensurate CDW-Mott insulating phase but with a smaller CDW amplitude. Moreover, we find that the long-lived state emerges only under strong photoexcitation and has no evidence when the photoexcitation strength is weak.

description: We develop a perturbative technique for solving Markovian quantum dissipative dynamics, with the perturbation parameter being a small gap in the eigenspectrum. As an example, we apply the technique and straightforwardly obtain analytically the dynamics of a three-level system with quasidegenerate excited states, where quantum coherences persist for very long times, proportional to the inverse of the energy splitting squared. We then show how to bypass this long-lived coherent dynamics and accelerate the relaxation to thermal equilibration in a hyper-exponential manner, a Markovian quantum-assisted Mpemba-like effect. This hyper acceleration of the equilibration process manifests if the initial state is carefully prepared, such that its coherences precisely store the amount of population relaxing from the initial condition to the equilibrium state. Our analytical method for solving quantum dissipative dynamics readily provides equilibration timescales, and as such it reveals how coherent and incoherent effects interlace in the dynamics. It further advices on how to accelerate relaxation processes, which is desirable when long-lived quantum coherences stagnate dynamics.

description: In this work, we discuss the possibility to test Heavy Neutral Leptons (HNLs) using $``$Cosmic Ray Beam Dump$"$ experiments. In analogy with terrestrial beam dump experiments, where a beam first hits a target and is then absorbed by a shield, we consider high-energy incident cosmic rays impinging on the Earth's atmosphere and then the Earth's surface. We focus here on HNL production from atmospherically produced kaon, pion and $D$-meson decays, and discuss the possible explanation of the appearing Cherenkov showers observed by the SHALON Cherenkov telescope and the ultra-high energy events detected by the neutrino experiment ANITA. We show that these observations can not be explained with a long-lived HNL, as the relevant parameter space is excluded by existing constraints. Then we propose two new experimental setups that are inspired by these experiments, namely a Cherenkov telescope pointing at the horizon and shielded by the mountain cliff at Mount Thor, and a geostationary satellite that observes part of the Sahara desert. We show that the Cherenkov telescope at Mount Thor can probe currently untested HNL parameter space for masses below the kaon mass. We also show that the geostationary satellite experiment can significantly increase the HNL parameter space coverage in the whole mass range from 10 MeV up to 2 GeV and test neutrino mixing $|U_{\alpha4}|^2$ down to $10^{-11}$ for masses around 300 MeV.

description: We report the discovery of the transiting extrasolar planet HAT-P-49b. The planet transits the bright (V = 10.3) slightly evolved F-star HD 340099 with a mass of 1.54M_S and a radius of 1.83 R_S. HAT-P-49b is orbiting one of the 25 brightest stars to host a transiting planet which makes this a favorable candidate for detailed follow-up. This system is an especially strong target for Rossiter- McLaughlin follow-up due to the fast rotation of the host star, 16 km/s. The planetary companion has a period of 2.6915 d, mass of 1.73 M_J and radius of 1.41 R_J. The planetary characteristics are consistent with that of a classical hot Jupiter but we note that this is the fourth most massive star to host a transiting planet with both M_p and R_p well determined.

In this review, the weak limit theorem, that is, the asymptotic behavior, of the one-dimensional discrete time quantum walk is analytically shown. From the limit distribution of the discrete time quantum walk, the discrete time quantum walk can be taken as the quantum dynamical simulator of some physical systems.

description: Soon after the Gaia data release (DR) 3 in June 2022, some candidates (and one confirmed) of detached black hole (BH) - luminous companion (LC) binaries have been reported. Existing and future detections of astrometric BH-LC binaries will shed light on the spatial distribution of these systems, which can deepen our understanding of the natal kicks and the underlying formation mechanism of BHs. By tracking Galactic orbits of BH-LC binaries obtained from BSE, we find that distributions of BH mass and the height from the Galactic plane |z| would help us give a constraint on supernova model. We also indicate that the correlations of (i) orbital periods and eccentricities, and (ii) BH mass and $|z|$ could be clues for the strength of natal kick, and that the correlations of ($P$, $Z/Z_\odot$) may tell us a clue for common envelope (CE) efficiency. We also discuss the possibility of forming BH-LC binaries like the BH binary candidates reported in Gaia DR3 and Gaia BH 1, finding that if the candidates as well as the confirmed binary originate from isolated binaries, they favor models which produce low-mass BHs and have high CE efficiencies exceeding unity.

description: The cultivation of alley cropping agricultural wood is an opportunity to comply with the greening requirements of the common agricultural policy (CAP; 2014-2020), but farmers are not permitted to display the whole alley cropping system (ACS) as ecological focus area (EFA) in Germany. They can display the agricultural wood stripes separately as EFA instead. The willingness of farmers is of key importance for a successful establishment, but, so far, the acceptance of this greening measure is extremely low. The aim of this paper is therefore to point out factors which have linkages to the acceptance of ACS as EFAs by conducting an online survey among German conventional farmers. The results of the regression analysis show that factors such as attitude towards agricultural wood, level of professional education, location and social environment affect the acceptance of ACS as EFA. To conclude, starting points that promote this type of greening measure are identified.

description: The abundance ratios between isomers of a COM observed in the ISM provides valuable information about the chemistry and physics of the gas and eventually, the history of molecular clouds. In this context, the origin of an abundance of c-HCOOH acid of only 6% the isomer c-HCOOH abundance in cold cores, remains unknown. Herein, we explain the presence of c-HCOOH in dark molecular clouds through the destruction and back formation of c-HCOOH and t-HCOOH in a cyclic process that involves HCOOH and highly abundant molecules such as HCO+ and NH3. We use high-level ab initio methods to compute the potential energy profiles for the cyclic destruction/formation routes of c-HCOOH and t-HCOOH. Global rate constants and branching ratios were calculated based on the transition state theory and the master equation formalism under the typical conditions of the ISM. The destruction of HCOOH by reaction with HCO+ in the gas phase leads to three isomers of the cation HC(OH)2+. The most abundant cation can react in a second step with other abundant molecules of the ISM like NH3 to form back c-HCOOH and t-HCOOH. This mechanism explains the formation of c-HCOOH in dark molecular clouds. Considering this mechanism, the fraction of c-HCOOH with respect t-HCOOH is 25.7%. To explain the 6% reported by the observations we propose that further destruction mechanisms of the cations of HCOOH should be taken into account. The sequential acid-base (SAB) mechanism proposed in this work involves fast processes with very abundant molecules in the ISM. Thus, HCOOH very likely suffers our proposed transformations in the conditions of dark molecular clouds. This is a new approach in the framework of the isomerism of organic molecules in the ISM which has the potential to try to explain the ratio between isomers of organic molecules detected in the ISM.

description: Tumors bearing Ras mutations are notoriously difficult to treat. Drug combinations targeting the Ras protein or its pathway have also not met with success. Pathway drug cocktails, which are combinations aiming at parallel pathways, appear more promising; however, to be usefully exploited, a repertoire of classified pathway combinations is desirable. This challenge would be facilitated by the availability of the structural network of signaling pathways. When integrated with functional and systems-level clinical data they can be powerful in advancing novel therapeutic platforms. Based on structural knowledge, drug cocktails may tear into multiple cellular processes that drive tumorigenesis, and help in deciphering the interrelationship between Ras mutations and the rewired Ras network. The pathway drug cocktail paradigm can be applied to other signaling protein targets.

description: In this study, the structural and magnetic properties of group-IV-doped monolayer GaN were systematically investigated by first-principles calculations. Among all the group-IV dopants, only Ge and Sn atoms prefer to substitute the Ga atom of monolayer GaN and form a buckling structure with a magnetic moment of 1 $μ_B$ per dopant. The N-rich growth conditions are more desirable for such a substitution process than the Ga-rich grow conditions. With a large diffusion barrier vertical to the monolayer GaN, both Ge and Sn atoms tend to stay on the same side of monolayer GaN with an antiferromagnetic coupling between them. When intrinsic vacancies exist in monolayer GaN, the magnetic moments of group-IV dopants vanish due to the charge transferring from the dopants to Ga or N vacancies. The precondition creation of Ga vacancies, a plentiful supply of Ge or Sn dopants, and the N-rich conditions can be adopted to maintain the magnetic properties of group-IV-doped monolayer GaN. These theoretical results help to promote the applications of 2D GaN-based materials in spintronics.

description: We consider new physics contributions to the top-quark forward-backward asymmetry from a neutral $V^0_8$ or charged $V^+_8$ color-octet vector exchanged in the $t$-channel. We study the phenomenological constraints on these particles arising from the Tevatron and LHC7 measurements and compare them with those on their color singlet counterparts $Z^\prime$ and $W^\prime$. We find that the color octets fare better than the singlets in that they generate a lower $A_C$, a lower high-invariant mass cross-section at LHC7 and a lower same sign top-pair cross-section. However, they also generate a lower $A_{FB}$ than their color-singlet counterparts.

description: It is known that the violation of Svetlichny inequality by any three-qubit state described by the density operator $ρ_{ABC}$ witness the genuine non-locality of $ρ_{ABC}$. But it is not an easy task as the problem of showing the genuine non-locality of any three-qubit state reduces to the problem of a complicated optimization problem. Thus, the detection of genuine non-locality of any three-qubit state may be considered a challenging task. Therefore, we have taken a different approach and derived the lower and upper bound of the expectation value of the Svetlichny operator with respect to any three-qubit state to study this problem. The expression of the obtained bounds depends on whether the reduced two-qubit entangled state is detected by the CHSH witness operator or not. It may be expressed in terms of the following quantities such as (i) the eigenvalues of the product of the given three-qubit state and the composite system of single qubit maximally mixed state and reduced two-qubit state and (ii) the non-locality of reduced two-qubit state. We then achieve the inequality whose violation may detect the genuine non-locality of any three-qubit state. A few examples are cited to support our obtained results. Lastly, we discuss its possible implementation in the laboratory.

description: An important part of the ontogeny of social mammals is the establishment of social relationships with non-mothers. Mothers may influence this socialization process, but other factors like the number and kind of potential partners available may also be important. In matrilineal societies, variation in allomaternal social experience is also likely to differ for males and females, relating to differences in their respective life histories. We investigated differences in non-maternal social relationships of 12 infant blue monkeys (Cercopithecus mitis stuhlmanni) in their first six months of life in a wild population. Based on previous findings that blue monkey infants develop spatial independence from their mothers at a relatively early age, we expected that infants would also socialize with non-maternal group members early in life. As possible determinants of variation in infant socialization, we evaluated the effects of age, sex, group composition, and timing of birth relative to the birth season. Allomaternal social relationships of infants differed between social groups, largely but not exclusively in response to differences in group composition. Adjusting for these group differences, we found that infants generally avoided spatial proximity to non-maternal adult females, whereas they associated more than expected by chance with other infants and large juvenile females, when away from their mothers. Close spatial association with other adult females and small juveniles increased when infants were near their mothers. Association with other infants decreased with proximity to the mother, apparently because peer playgroups led infants away from their mothers. Infants were spatially well integrated into the core of the group, associating with most available adult and large juvenile partners. Male infants spent more time in social play than females, and engaged in more rough-and-tumble play bouts, and in bouts of longer duration, than females. Large juvenile females regularly took care of infants, whereas adult females rarely acted as caretakers. There were no sex differences in behavior directed towards infants by non-mothers, but female infants associated more than male infants with adultfemales when away from their mothers. Although sex differences in social play correspond to similar differences in the importance of fighting skills for adults, alternative explanations for the observed pattern remain plausible. Our data support the hypothesis that allomaternal care functions as infant handling practice for nulliparous females. The relatively rapid social development we observed in our subjects contrasts with the generally slow life history of the species and suggests that developmental rates during infancy and juvenility are promoted and constrained by different factors.

Variable participation in the defense of communal feeding territories by blue monkeys in the Kakamega Forest, Kenya

Animal behavior

description: While blue monkey groups often defend feeding territories against their neighbours, group members do not participate equally. Data spanning 5 years and 5 wild groups were used to address factors that might explain variable participation, both across age-sex classes and among individual adult females. Adult females participated most, although there was a 9-fold difference between those individuals who participated most and least. Juvenile participation increased with age, but female juveniles participated more than males in each cohort. Male juveniles reduced participation as they approached the age of natal emigration. In general, it seems that adult participation patterns are acquired gradually during ontogeny. Among adult females, those with infants participated less than those without infants, and higher-ranking females participated more than lower-rankers. The presence of matrilineal kin in the group did not generally affect participation by adult females. Age-sex class differences and the effect of infant presence can be explained in terms of relative costs and benefits to participation. The lack of a kinship effect was unexpected. The rank effect was also unanticipated, given that rank does not predict reproductive success in this species. High-ranking females may face lower costs, offer staying incentives to lower-ranked females, or trade services with them.

Submitted for publication on September 26, 1930. See [1] in the Comments with References section before reading this English translation.] The gravitational field generated by an electromagnetic field is calculated using of laws of quantum mechanics and it is shown that the resulting gravitational energy turns out to be infinitely large, raising a new difficulty for the Heisenberg-Pauli quantum theory of wave fields. In addition, the transition processes in first-order approximation involving light and gravitational quanta are briefly discussed.

description: We demonstrate a trapped-ion system with two competing dissipation channels, implemented independently on two ion species co-trapped in a Paul trap. By controlling coherent spin-oscillator couplings and optical pumping rates we explore the phase diagram of this system, which exhibits a regime analogous to that of a (phonon) laser but operates close to the quantum ground state with an average phonon number of $\bar{n}<10$. We demonstrate phase locking of the oscillator to an additional resonant drive, and also observe the phase diffusion of the resulting state under dissipation by reconstructing the quantum state from a measurement of the characteristic function.

description: We report a low-temperature specific heat study of high-quality single crystals of the heavily hole doped superconductor Ca$_{0.32}$Na$_{0.68}$Fe$_2$As$_2$. This compound exhibits bulk superconductivity with a transition temperature $T_c \approx 34$\,K, which is evident from the magnetization, transport, and specific heat measurements. The zero field data manifests a significant electronic specific heat in the normal state with a Sommerfeld coefficient $γ\approx 53$ mJ/mol K$^{2}$. Using a multi-band Eliashberg analysis, we demonstrate that the dependence of the zero field specific heat in the superconducting state is well described by a three-band model with an unconventional s$_\pm$ pairing symmetry and gap magnitudes $Δ_i$ of approximately 2.35, 7.48, and -7.50 meV. Our analysis indicates a non-negligible attractive intraband coupling,which contributes significantly to the relatively high value of $T_c$. The Fermi surface averaged repulsive and attractive coupling strengths are of comparable size and outside the strong coupling limit frequently adopted for describing high-$T_c$ iron pnictide superconductors. We further infer a total mass renormalization of the order of five, including the effects of correlations and electron-boson interactions.

description: Glycerol is a hygroscopic fluid that spontaneously absorbs water vapor from the atmosphere. For applications involving glycerol, care must be taken to avoid exposure to humidity, since its viscosity decreases quickly as water is absorbed. We report experimental measurements of the viscosity of glycerol in a parallel-plate rheometer where the outer interface is exposed to atmosphere. The measurements decrease with time as water is absorbed from the atmosphere and transported throughout the glycerol via diffusion and advection. Measured viscosities drop faster at higher relative humidities, confirming the role of hygroscopicity on the transient viscosities. The rate of viscosity decrease shows a non-monotonic relationship with the rheometer gap height. This behavior is explained by considering the transition from diffusion-dominated transport in the narrow gap regime to the large gap regime where transport is dominated by inertia-driven secondary flows. Numerical simulations of the water absorption and transport confirm this non-monotonic behavior. The experimental viscosity measurements show unexpectedly fast decreases at very small gap heights, violating the parallel-plate, axisymmetric model. We propose that this drop-off may be due to misalignment in the rheometer that becomes non-negligible for small gaps. Theoretical considerations show that secondary flows in a misaligned rheometer dominate the typical secondary inertial flows in parallel-plate rheometers at small gaps. Finally, simulations in a misaligned parallel-plate system demonstrate the same sharp drop-off in viscosity measurements at small gap heights. This modeling can be used to estimate the gap height where misalignment effects dominate the transient glycerol viscosity measurements.
