description: We address the locality problem arising in simulations, which take the square root of the staggered fermion determinant as a Boltzmann weight to reduce the number of dynamical quark tastes. A definition of such a theory necessitates an underlying local fermion operator with the same determinant and the corresponding Green's functions to establish causality and unitarity. We illustrate this point by studying analytically and numerically the square root of the staggered fermion operator. Although it has the correct weight, this operator is non-local in the continuum limit. Our work serves as a warning that fundamental properties of field theories might be violated when employing blindly the square root trick. The question, whether a local operator reproducing the square root of the staggered fermion determinant exists, is left open.

description: Vehicle-to-everything (V2X) communication and services have been garnering significant interest from different stakeholders as part of future intelligent transportation systems (ITSs). This is due to the many benefits they offer. However, many of these services have stringent performance requirements, particularly in terms of the delay/latency. Multi-access/mobile edge computing (MEC) has been proposed as a potential solution for such services by bringing them closer to vehicles. Yet, this introduces a new set of challenges such as where to place these V2X services, especially given the limit computation resources available at edge nodes. To that end, this work formulates the problem of optimal V2X service placement (OVSP) in a hybrid core/edge environment as a binary integer linear programming problem. To the best of our knowledge, no previous work considered the V2X service placement problem while taking into consideration the computational resource availability at the nodes. Moreover, a low-complexity greedy-based heuristic algorithm named "Greedy V2X Service Placement Algorithm" (G-VSPA) was developed to solve this problem. Simulation results show that the OVSP model successfully guarantees and maintains the QoS requirements of all the different V2X services. Additionally, it is observed that the proposed G-VSPA algorithm achieves close to optimal performance while having lower complexity.

description: Objective: Although the long-term consequences of acquired brain injury are frequent and diverse, care and support over the longer term is an under-addressed issue. This study aims to identify the perceived needs of people with acquired brain injury and their partners. Methods: Interviews with four focus groups of people with brain injury (n = 17) and three partner groups (n = 19) were audio- and videotaped, transcribed verbatim and analyzed using inductive content analysis. Results: Needs were perceived on the intrapersonal, social, healthcare and societal levels, focusing on three themes: 1) Adaptation to changes, including awareness of consequences, acceptance, role changes and dealing with these; 2) Understanding from relatives/friends, professionals, institutions and society; 3) Timely, individualized care, involving information, transition to home, searching for support, peer support and support for partner/family. Discussion: The variety and complexity of needs show that people with brain injury and their partners need to find a new balance in order to live a fulfilling life despite the consequences of brain injury. The overarching need for continuity of care from the transition to home onwards provides important implications for supporting the process of learning how to live well with brain injury.
Non-perturbative Faddeev-Popov formula and infrared limit of QCD

description: We show that an exact non-perturbative quantization of continuum gauge theory is provided by the Faddeev-Popov formula in Landau gauge, $\d(\p \cdot A) \det[-\p \cdot D(A)] \exp[-S_{\rm YM}(A)]$, restricted to the region where the Faddeev-Popov operator is positive $-\p \cdot D(A) > 0$ (Gribov region). Although there are Gribov copies inside this region, they have no influence on expectation-values. The starting point of the derivation is stochastic quantization which determines the Euclidean probability distribution $P(A)$ by a method that is free of the Gribov critique. In the Landau-gauge limit the support of $P(A)$ shrinks down to the Gribov region with Faddeev-Popov weight. The cut-off of the resulting functional integral on the boundary of the Gribov region does not change the {\it form} of the Dyson-Schwinger equations, because $\det[-\p \cdot D(A)]$ vanishes on the boundary, so there is no boundary contribution. However this cut-off does provide {\it supplementary conditions} that govern the choice of solution of the DS equations. In particular the "horizon condition", though consistent with the perturbative renormalization group, puts QCD into a non-perturbative phase. The infrared asymptotic limit of the DS equations of QCD is obtained by neglecting the Yang-Mills action $S_{\rm YM}$. We sketch the extension to a BRST-invariant formulation. In the infrared asymptotic limit, the BRST-invariant action becomes BRST-exact, and defines a topological quantum field theory with an infinite mass gap. Confinement of quarks is discussed briefly.

description: The asymptotic analysis of the radiation pattern of a classical dipole in a photonic crystal possessing an incomplete photonic bandgap is presented. The far-field radiation pattern demonstrates a strong modification with respect to the dipole radiation pattern in vacuum. Radiated power is suppressed in the direction of the spatial stopband and strongly enhanced in the direction of the group velocity, which is stationary with respect to a small variation of the wave vector. An effect of radiated power enhancement is explained in terms of \emph{photon focusing}. Numerical example is given for a square-lattice two-dimensional photonic crystal. Predictions of asymptotic analysis are substantiated with finite-difference time-domain calculations, revealing a reasonable agreement.

SPECIES CHARACTERISATION. — Shell low trochiform; five weakly shouldered teleoconch whorls separated by narrowly impressed suture; sculpture of numerous, fine, irregular spiral cords; axial sculpture reduced to prosocline growth-lines; base depressed bearing numerous concentric cords; umbilicus well developed, moderately narrow and deep; columella short, straight, oblique; colour pattern of red-orange zigzag flammules preserved in all specimens.
DISTRIBUTION. — (Late Pliocene-Early Pleistocene: NSB and Irish Sea [Wood 1848; Harmer 1923] likely based on misidentifications [Pouwer & Wesselingh 2012]). Lower Pleistocene: Atlantic, Selsoif, France (this paper). Upper Pleistocene: British Isles (Harmer 1923). — Holocene: NSB (Strand Petersen 2004).Today this species is predominantly found in cooler waters in the NSB and along the European Atlantic coasts North Norway, Iceland to Gibraltar (Fretter & Graham 1977) and adjacent western Mediterranean (Giannuzzi-Savelli et al. 1994). Records south of Gibraltar in the Atlantic and into the Mediterranean, such as southManousis (2021), need to be confirmed.
REMARKS
Based on molecular data, this species is now placed in the genus Steromphala Gray, 1847 (Affenzeller et al. 2017). Most specimens from Selsoif are small and depressed (Fig. 4I 1-I 3). One large, gerontic specimen (Fig. 4H 1-H 3) is taller spired, with more strongly shouldered whorls, the shoulder marked by two slightly strengthened cords. In general, the Selsoif specimens have slightly more shouldered whorls than extant specimens, but we consider them conspecific.

description: We argue that the accuracy by which the isochron parameters of the decay $^{187}{\rm Re}\to ^{187}{\rm Os}$ are determined by dating iron meteorites may not directly constrain the possible time-dependence of the decay rate and hence of the fine-structure constant $α$. From this point of view, some of the attempts to analyze the Oklo constraint and the results of the QSO absorption lines are re-examined.

description: No abstracts are to be cited without prior reference to the author.Marine spatial management is confronted with complex situations in European countries due to multiple contexts, stakeholders, interests and management possibilities. As illustrated by some existing European Marine Spatial Plans (MSP) (see for instance the Dutch Integrated Management Plan North Sea 2015), the high level goals and intentions are frequently formulated by using the terms ‘sustainable’ and ‘integrated’, which tend to include every activity and objective. In this way they do not necessarily cause any high level conflict or stimulate discussion, as their broadness captures economic, social and ecological objectives, as well as all sectors and interests operating in the coastal zone. In other words, the existing MSPs are to general to suggest any priority to an allocation strategy for certain activities or zoning, although they may provide a nice starting point for further discussion.

We have resolved for the first time the highly energetic molecular outflow in this region. At this resolution, the outflow is definitely bipolar and appears to originate in a 1.3 mm continuum source. The continuum source peaks in the center of the HII region. The axis of the outflow lines up with a recently discovered O5V star.

On the Nature of the Sommerfeld-Brillouin Forerunners (or Precursors)

Year: 2019

description: We present a brief overview of Sommerfeld's forerunner signal, which occurs when a monochromatic plane-wave (frequency ω=ω_s) suddenly arrives, at time t=0 and at normal incidence, at the surface of a dispersive dielectric medium of refractive index n(ω). Deep inside the dielectric host at a distance z0 from the surface, no signal arrives until t=z0/c, where c is the speed of light in vacuum. Immediately after this point, a weak but extremely high frequency signal is observed at z=z0. This so-called Sommerfeld forerunner (or precursor) is highly chirped, meaning that its frequency, which is much greater than ω_s immediately after t=z0/c, declines rapidly with the passage of time. The incident light with its characteristic frequency ω_s eventually arrives at t~z0/vg , where vg is the group velocity of the incident light inside the host medium. Brillouin has identified a second forerunner that occupies the interval between the end of the Sommerfeld forerunner at t~n(0)z0/c and the beginning of the steady signal. This second forerunner is commonly referred to as the Brillouin forerunner (or precursor). Given that the incident wave has a sudden start at t=0, its frequency spectrum spans the entire range of frequencies from minus infinity to infinity. Consequently, the high-frequency first forerunner cannot be considered a superoscillation, nor can the low-frequency second forerunner be regarded as a suboscillation. The goal of the present paper is to extend the Sommerfeld-Brillouin theory of precursors to bandlimited incident signals, in an effort to determine the conditions under which these precursors would continue to exist, and to answer the question as to whether or not such precursors, upon arising from a bandlimited incident signal, constitute super- or sub-oscillations.

description: Arguments about the conservation laws of energy and momentum in the micro-world being statistical or strict began in 1924, and conflicting viewpoints remain today. The former is mainly supported theoretically, but the latter has been proved by many experiments. Here we explain that in principle, the strict conservation law of momentum always holds in the entangled state form of the momentum eigenstates of a closed composite system with interactions among subsystems, by expanding the total wave function to the sum of the products of momentum eigenstates of subsystems. Common scenario is that one of the two subsystems of a composite system is large or strong, its state remains approximately unchanged in a short time and the entangled state can be approximately written as a product state, which can be easily deduced from the paper of Haroche's group in 2001. The considered micro-subsystem can be approximately represented as the superposition of its different momentum eigenstates; therefore, the approximation can be used to explain why the law holds statistically for the subsystem and for any single particle due to neglecting the interactions with the large subsystem or the environment. So the two momentum conservation laws reasonably hold without conflicts.

Modelling Suspended Sand Transport Under Breaking Waves
Creators: name: Lim, Gabriel
Publisher: name: University of East London
Year: 2021

description: The modelling of coastal morphodynamics has often been hindered by the lack of robustness/accuracy of constituent formulae, especially sediment transport formulae in the breaking and swash zones. Consequently, modellers are often forced to rely on crude calibration efforts and practical models consisting of empirical tuning-constants, to obtain favourable model results. Such methods are often unavoidable however due to theoretical limitations of existing models. The aim of this thesis is therefore to improve accuracy and applicability of suspended sand transport models for breaking wave conditions, for implementation into morphodynamic modelling studies. Several existing suspended sand transport models (6 reference concentration C₀ + 5 concentration profile C[z]) models were evaluated quantitatively and qualitatively against one another, and against state-of-the-art high-resolution datasets which were collected under large-scale breaking wave conditions. Numerous limitations were observed in existing models, with the most common of these being their inability to accurately replicate suspended transport patterns in multiple cross-shore regions. This was due to various issues, such as not adequately accounting for the effects of breaking-induced turbulent kinetic energy on resulting sand transport. This resulted in large discrepancies between computed and measured transport particularly in the highly turbulent breaking zone. Such poor performance in computing C₀ and C[z] had residual effects on the resulting suspended flux (uC[z]) and current-related transport rate (qsc) computations also, which are essential to the accurate modelling of morphodynamics, particularly in the medium- to long-term. A novel set of suspended sand transport (C₀ + C[z]) models (“L19”) were developed for breaking wave conditions and evaluated against the aforementioned existing models and datasets. The L19 formulae showed significantly greater performance than all existing models, indicating excellent agreement with measured data in all tested cross-shore regions. These improvements led to considerably better estimations of uC[z] and qsc, which have promising implications for future morphodynamic modelling.
Magnets in an electric field: hidden forces and momentum conservation

description: In 1967 Shockley and James addressed the situation of a magnet in an electric field. The magnet is at rest and contains electromagnetic momentum, but there was no obvious mechanical momentum to balance this for momentum conservation. They concluded that some sort of mechanical momentum, which they called "hidden momentum", was contained in the magnet and ascribed this momentum to relativistic effects, a contention that was apparently confirmed by Coleman and Van Vleck. Since then, a magnetic dipole in an electric field has been considered to have this new form of momentum, but this view ignores the electromagnetic forces that arise when an electric field is applied to a magnet or a magnet is formed in an electric field. The electromagnetic forces result in the magnet gaining electromagnetic momentum and an equal and opposite amount of mechanical momentum so that it is moving in its original rest frame. This moving reference frame is erroneously taken to be the rest frame in studies that purport to show hidden momentum. Here I examine the analysis of Shockley and James and of Coleman and Van Vleck and consider a model of a magnetic dipole formed in a uniform electric field. These calculations show no hidden momentum.

description: Focal adhesion kinase (FAK) mediates vital cellular pathways during development. Despite its necessity, how FAK regulates and integrates with other signals during early embryogenesis remains poorly understood. We found that the loss of Fak1a impaired epiboly, convergent extension and hypoblast cell migration in zebrafish embryos. We also observed a clear disturbance in cortical actin at the blastoderm margin and distribution of yolk syncytial nuclei. In addition, we investigated a possible link between Fak1a and a well-known gastrulation regulator, Wnt5b, and revealed that the overexpression of fak1a or wnt5b could cross-rescue convergence defects induced by a wnt5b or fak1a antisense morpholino (MO), respectively. Wnt5b and Fak1a were shown to converge in regulating Rac1 and Cdc42, which could synergistically rescue wnt5b and fak1a morphant phenotypes. Furthermore, we generated several alleles of fak1a mutants using CRISPR/Cas9, but those mutants only revealed mild gastrulation defects. However, injection of a subthreshold level of the wnt5b MO induced severe gastrulation defects in fak1a mutants, which suggested that the upregulated expression of wnt5b might complement the loss of Fak1a. Collectively, we demonstrated that a functional interaction between Wnt and FAK signalling mediates gastrulation cell movements via the possible regulation of Rac1 and Cdc42 and subsequent actin dynamics.

description: The theory of inflation will be investigated as well as supersymmetry breaking in the context of supergravity, incorporating the target-space duality and the nonperturbative gaugino condensation in the hidden sector. We found an inflationary trajectory of a dilaton field and a condensate field which breaks supersymmetry at once. The model satisfies the slow-roll condition which solves the eta-problem. When the particle rolls down along the minimized trajectory of the potential V(S,Y) at a duality invariant point of T=1, we can obtain the e-fold value \sim 57. And then the cosmological parameters obtained from our model well match the recent WMAP data combined with other experiments. This observation suggests one to consider the string-inspired supergravity as a fundamental theory of the evolution of the universe as well as the particle theory.

description: Vacuum expectation value of the surface energy-momentum tensor is evaluated for a massive scalar field with general curvature coupling parameter subject to Robin boundary conditions on two parallel branes located on (D+1)-dimensional AdS bulk. The general case of different Robin coefficients on separate branes is considered. As an regularization procedure the generalized zeta function technique is used, in combination with contour integral representations. The surface energies on the branes are presented in the form of the sums of single brane and second brane-induced parts. For the geometry of a single brane both regions, on the left (L-region) and on the right (R-region), of the brane are considered. The surface densities for separate L- and R-regions contain pole and finite contributions. For an infinitely thin brane taking these regions together, in odd spatial dimensions the pole parts cancel and the total surface energy is finite. The parts in the surface densities generated by the presence of the second brane are finite for all nonzero values of the interbrane separation. It is shown that for large distances between the branes the induced surface densities give rise to an exponentially suppressed cosmological constant on the brane. In the Randall-Sundrum braneworld model, for the interbrane distances solving the hierarchy problem between the gravitational and electroweak mass scales, the cosmological constant generated on the visible brane is of the right order of magnitude with the value suggested by the cosmological observations.

Today this species is present from the Atlantic SW England (Fretter & Graham 1977) to southwards into the Mediterranean, Corsica (Van Aartsen et al. 1984).
REMARKS
There is some variation in shape in the specimen from Selsoif, some slightly more depressed than others and in some specimens the last portion of the last whorl is slightly disjunct. Dikoleps marianae Rubio, Dantart & Luque, 1998, from the Mediterranean Sea resembles D. cutleriana in having the teleoconch covered in fine spirals, even finer than those of D. cutleriana (40 vs 30; fide Rubio et al. 2004: 131) but the protoconch is rugose rather than smooth.

Publisher: name: Zenodo
Year: 2024

description: Agricultural techniques all around the world include the cultivation and evaluation of bananas. With improved accuracy, economy, and scalability, the application of Machine Learning (ML) approaches has transformed the evaluation of banana quality in recent years. Through the division of results into quality and grading, disease detection and classification, and comparative assessments of ML techniques, this paper thoroughly examines the field of ML applications in banana analysis. Distinguished results comprise the creation of Dual Channel Banana Grading Systems with Deep Learning Based Accuracy Rates Reaching Up to 99% and the application of Convolutional Neural Networks (CNNs) with 90%+ accuracy for illness classification. Examining issues like model robustness and data bias, the paper goes on to clarify the implications and constraints of machine learning in banana assessment.This paper highlights the revolutionary potential of machine learning (ML) in promoting banana cultivation through thorough analysis and comparison with previous research. In order to improve agricultural techniques and make them more accurate, efficient, and sustainable, it is important to continue researching and developing machine learning models that are specifically designed to address the difficulties involved in growing bananas.

description: Valley Hall effect is an appearance of the valley current in the direction transverse to the electric current. We develop the microscopic theory of the valley Hall effect in two-dimensional semiconductors where the electrons are dragged by the phonons or photons. We derive and analyze all relevant contributions to the valley current including the skew-scattering effects together with the anomalous contributions caused by the side-jumps and the anomalous velocity. The partial compensation of the anomalous contributions is studied in detail. The role of two-phonon and two-impurity scattering processes is analyzed. We also compare the valley Hall effect under the drag conditions and the valley Hall effect caused by the external static electric field.

We find clear evidence for a line of continuous quantum phase transitions for subohmic bath exponents 0

Vibration of the Dimer on Si(001) Surface Excited by STM Current

Subjects: subject: Condensed Matter (cond-mat)

description: The vibration of the dimer excited by STM current on Si(001) surface is investigated. We describe this system by the Hamiltonian which has the electron-vibration coupling term as the key ingredient. In order to characterize the transition rates induced by STM current between vibrational states we have introduced the effective temperature of the vibration which differs from the temperature of the substrate. The behavior of the effective temperature depends on the substrate temperature and STM current in highly nonlinear manner and qualitatively changes around 50K of the substrate temperature. At lower temperatures, the effective temperature strongly deviates from the substrate temperature and reaches a few hundred Kelvin for the typical values of STM current. At higher substrate temperatures, the effective temperature reduces to the substrate temperature. On the basis of these behaviors of the effective temperature, we solve the puzzle of the symmetric-asymmetric crossover in dimer images of STM observation in the ordered state of c(4 x 2).
Non-stochastic behavior of atomic surface diffusion on Cu(111) at all temperatures

description: Atomic diffusion is usually understood as a succession of random, independent displacements of an adatom over the surface's potential energy landscape. Nevertheless, an analysis of Molecular Dynamics simulations of self-diffusion on Cu(111) demonstrates the existence of different types of correlations in the atomic jumps at all temperatures. Thus, the atomic displacements cannot be correctly described in terms of a random walk model. This fact has a profound impact on the determination and interpretation of diffusion coefficients.

Baryon Number Transfer in Hadron+Nucleus and Nucleus+Nucleus Collisions: A Link between Elementary and Complex Interactions
Creators: name: Varga, D.

Year: 2003
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The baryon number transfer is studied in elementary and complex hadronic interactions at the CERN experiment NA49 at the SPS, at 158 AGeV beam energy (\sqrt{s}=17.2 GeV). A two component picture is proposed, which builds up the net proton distribution from a target and a projectile component. Using pion beam, the projectile component is experimentally determined for p+p and p+A interactions. A similar stopping behaviour of the projectile component is found for p+A and A+A interactions. Based on these observations, the baryon transfer is assumed to provide a common scale of inelasticity in p+p, p+A and A+A interactions. A model-independent way is proposed to predict the pion multiplicity in A+A.

description: Spin-dependent charge transport in magnetic tunnel junctions (MTJs) can be manipulated by a temperature gradient, which can be utilized for spintronic and spin caloritronic applications. Evaluation of the thermally induced phenomena requires knowledge of the temperature differences across the oxide tunnel barrier adjacent to the ferromagnetic (FM) leads. However, it is challenging to accurately measure thermal properties of an oxide tunnel barrier consisting of only a few atomic layers. In this work, we experimentally interrogate the temperature evolutions in Ru/oxide/FM/seed/MgO (oxide=MgO, MgAl2O4; FM=Co, CoFeB; seed=Pt, Ta) structures having perpendicular magnetic anisotropy using ultrafast thermometry. The Ru layer is optically thick and heated by ultrafast laser pulses; the subsequent temperature changes are monitored using thermoreflectance of Ru and magneto-optic Kerr effect (MOKE) of the FM layers. We independently measure the response times of Co and CoFeB magnetism using quadratic MOKE and obtain τem=0.2 ps for Co and 2 ps for CoFeB. These time scales are much shorter than the time scale of heat transport through the oxide tunnel barrier, which occurs at 10-3000 ps. We determine effective thermal conductivities of MgO and MgAl2O4 tunnel barriers in the range of 0.4-0.6 W m-1 K-1, comparable to an estimate of the series conductance of the Ru/oxide and oxide/FM interfaces and an order of magnitude smaller than the thermal conductivity of MgO thin films. We find that the electron-phonon thermal conductance near the tunnel barrier is only a factor of 5-12 larger than the thermal conductance of the oxide tunnel barrier. Therefore, the drop in the electronic temperature is approximately 20-30% larger than the drop in the phonon temperature across the tunnel barrier.
