description: We propose a non-thermal mechanism of weak microwave field impact on a nerve fiber. It is shown that in the range of about 30 - 300 GHz there are strongly pronounced resonances associated with the excitation of ultrasonic vibrations in the membrane as a result of interaction with electromagnetic radiation. These vibrations create acoustic pressure which may lead to the redistribution of the protein transmembrane channels, and, thus, changing the threshold of the action potential excitation in the axons of the neural network. The influence of the electromagnetic microwave radiation on various specific areas of myelin nerve fibers was analyzed: the nodes of Ranvier, and the so-called initial segment - the area between the neuron hillock and the first part of the axon covered with the myelin layer. It is shown that the initial segment is the most sensitive area of the myelined nerve fibers from which the action potential normally starts.

description: In this paper, we define a new type of decoherent quantum random walks with parameter $0\le p\le 1$, which becomes a unitary quantum random walk (UQRW) when $p=0$ and an open quantum random walk (OPRW) when $p=1$ respectively. We call this process a partially open quantum random walk (POQRW). We study the limiting distribution of a POQRW on $Z^1$ subject to decoherence on coins with $n$ degrees of freedom, which converges to a convex combination of normal distributions if the superoperator $\mathcal{L}_{kk}$ satisfies the eigenvalue condition, that is, 1 is an eigenvalue of $\mathcal{L}_{kk}$ with multiplicity one and all other eigenvalues have absolute values less than 1. A Perron-Frobenius type of theorem is provided in determining whether or not the superoperator satisfies the eigenvalue condition. Moreover, we compute the limiting distributions of characteristic equations of the position probability functions for $n=2$ and 3.

description: Gears are key components of several industrial applications, being subjected to wear during operation. Scuffing, micropitting and pitting are common types of gear failure modes that can happen. The failure analysis is usually performed by visual inspection, and therefore is subjected to human bias. Hence, it is important to implement objective metrics to quantify of these failure modes. In this investigation, the 3D topography of gears exhibiting micropitting, pitting, and scuffing failure modes were measured with a white light interferometer. These topographies were evaluated in terms of function roughness parameters (S_pk, S_k, and S_vk) as per ISO 25178-2. The results of the function parameters highlighted differences in the severity of damage, starting from the micropitting, and increasing to the scuffing and further to the pitting failure modes. Besides, using the peak-to-dale ratio (S_pk⁄S_vk ), it was possible to differentiate the scuffing failure from the micropitting and the pitting failures. This investigation demonstrated that it is possible to perform an objective quantification of gear failure modes using functional roughness parameters.

description: This paper presents a hydrodynamical model describing the evolution of the gas reinserted by stars within a rotating young nuclear star cluster (NSC). We explicitly consider the impact of the stellar component to the flow by means of a uniform insertion of mass and energy within the stellar cluster. The model includes the gravity force of the stellar component and a central supermassive black hole (SMBH), and accounts for the heating from the central source of radiation and the radiative cooling of the thermalized gas. By using a set of parameters typical for NSCs and SMBHs in Seyfert galaxies our simulations show that a filamentary/clumpy structure is formed in the inner part of the cluster. This "torus" is Compton thick and covers a large fraction of the sky (as seen from the SMBH). In the outer parts of the cluster a powerful wind is produced, that inhibits the infall of matter from larger scales and thus the NSC-SMBH interplay occurs in isolation.

description: Stochasticity in gene expression gives rise to fluctuations in protein levels across a population of genetically identical cells. Such fluctuations can lead to phenotypic variation in clonal populations, hence there is considerable interest in quantifying noise in gene expression using stochastic models. However, obtaining exact analytical results for protein distributions has been an intractable task for all but the simplest models. Here, we invoke the partitioning property of Poisson processes to develop a mapping that significantly simplifies the analysis of stochastic models of gene expression. The mapping leads to exact protein distributions using results for mRNA distributions in models with promoter-based regulation. Using this approach, we derive exact analytical results for steady-state and time-dependent distributions for the basic 2-stage model of gene expression. Furthermore, we show how the mapping leads to exact protein distributions for extensions of the basic model that include the effects of post-transcriptional and post-translational regulation. The approach developed in this work is widely applicable and can contribute to a quantitative understanding of stochasticity in gene expression and its regulation.

description: A regularization procedure developed in [1] for the integral curvature invariants on manifolds with conical singularities is generalized to the case of squashed cones. In general, the squashed conical singularities do not have rotational O(2) symmetry in a subspace orthogonal to a singular surface $Σ$ so that the surface is allowed to have extrinsic curvatures. A new feature of the squashed conical singularities is that the surface terms in the integral invariants, in the limit of small angle deficit, now depend also on the extrinsic curvatures of $Σ$. A case of invariants which are quadratic polynomials of the Riemann curvature is elaborated in different dimensions and applied to several problems related to entanglement entropy. The results are in complete agreement with computations of the logarithmic terms in entanglement entropy of 4D conformal theories [2]. Among other applications of the suggested method are logarithmic terms in entanglement entropy of non-conformal theories and a holographic formula for entanglement entropy in theories with gravity duals.

description: Our ultimate goal is to probe the nature of the collimator of the outflows in the pre PN CRL618. CRL618 is uniquely suited for this purpose owing to its multiple, bright, and carefully studied finger-shaped outflows east and west of its nucleus. We compare new HST images to images in the same filters observed as much as 11 y previously to uncover large proper motions and surface brightness changes in its multiple finger-shaped outflows. The expansion age of the ensemble of fingers is close to 100y. We find strong brightness variations at the fingertips during the past decade. Deep IR images reveal a multiple ring- like structure of the surrounding medium into which the outflows propagate and interact. Tightly constrained three-dimensional ("3D") hydrodynamic models link the properties of the fingers to their possible formation histories. We incorporate previously published complementary information to discern whether each of the fingers of CRL618 are the results of steady, collimated outflows or a brief ejection event that launched a set of bullets about a century ago. Finally, we argue on various physical grounds that fingers of CRL618 are likely to be the result of a spray of clumps ejected at the nucleus of CRL618 since any mechanism that form a sustained set of unaligned jets is unprecedented.

title: Coral Gables: a contemporary urban utopia

description: The historic City of Coral Gables was designed and developed starting from 1921 as a full-fledged new town, following the dreams and vision of its founder George Merrick. Since the very beginning the development was conceived not as a mere residential suburb but as a functionally integrated garden city. The large-scale plan reveals the influences of the City Beautiful Movement (use of the geometric pattern, the rigorous grid that orders the functional parts of the system, and the use of the diagonals) and the Park Movement and Garden City principles (progressive opening up of the urban structure to accommodate the green public spaces, the canals, the curving street), which guided the harmonious design and planning of the residential suburbs, business and craft sections, public spaces and venues, “entrances” at the main access to the city from Miami, “plazas” at the principal boulevard intersections, public buildings such as schools, churches, the city hall, hotels, and the University. Today’s cityscape is almost unchanged in its essential features, in its architectural components of Mediterranean inspired style, as well as in the urban relationships between the various historic elements originally designed by George E. Merrick. If this is true especially for the residential areas of the first section, built architectural elements such as gates and squares, the scale ratio between the new buildings and the few remaining historical fabric in the downtown area may not be fully adjusted. The investigation of the current preservation policies and tools has revealed that state and local laws have been effectively enforced by the Local Administration and suggests to design the implementation of a database, built on the Florida Master Site File, to support policy decision making, management and research.

description: We study dynamic self-organisation and order-disorder transitions in a two-dimensional system of self-propelled particles. Our model is a variation of the Vicsek model, where particles align the motion to their neighbours but repel each other at short distances. We use computer simulations to measure the orientational order parameter for particle velocities as a function of intensity of internal noise or particle density. We show that in addition to the transition to an ordered state on increasing the particle density, as reported previously, there exists a transition into a disordered phase at the higher densities, which can be attributed to the destructive action of the repulsions. We demonstrate that the transition into the ordered phase is accompanied by the onset of algebraic behaviour of the two-point velocity correlation function and by a non-monotonous variation of the velocity relaxation time. The critical exponent for the decay of the velocity correlation function in the ordered phase depends on particle concentration at low densities but assumes a universal value in more dense systems.

description: In a previous work, we reported on the discovery of supersonic magnetic upflows on granular cells in data from the {\sc Sunrise}/IMaX instrument. In the present work we investigate the physical origin of these events employing data of the same instrument but with higher spectral sampling. By means of the inversion of Stokes profiles we are able to recover the physical parameters (temperature, magnetic field, line-of-sight velocity, etc) present in the solar photosphere at the time of these events. The inversion is performed in a Monte-Carlo-like fashion, that is, repeating it many times with different initializations and retaining only the best result. We find that many of the events are characterized by a reversal in the polarity of the magnetic field along the vertical direction in the photosphere, accompanied by an enhancement in the temperature and by supersonic line-of-sight velocities. In about half of the studied events, large blue-shifted and red-shifted line-of-sight velocities coexist above/below each other. These features can be explained in terms of magnetic reconnection, where the energy stored in the magnetic field is released in the form of kinetic and thermal energy when magnetic field lines of opposite polarities coalesce. However, the agreement with magnetic reconnection is not perfect and therefore, other possible physical mechanisms might also play a role.

Exchange, Extraction, and the Politics of Ideological Money Laundering in Egypt's New Kingdom Empire

description: Egypt's New Kingdom imperial government routinely utilized Syro-Palestinian temples to mask a variety of key economic and political transactions. Pharaohs embellished temples in the territory of valued vassals and gave gifts of divine statues fashioned out of precious materials. The statues themselves could serve as bribes, designed to purchase the allegiance of key vassals. Further, if a local deity could be credibly syncretized with an Egyptian counterpart, as was the Lady of Byblos, the pharaoh might continue to provide "offerings" in perpetuity that conveniently disguised payment for local resources and/or ongoing subsidies as royal largesse bestowed upon an Egyptian god. Statues in Egypt and Nubia were typically bestowed upon temples together with parcels of land to support them. If, as is likely, the same held true in Syria-Palestine, an Egyptian-sponsored statue would receive income that might, depending on circumstances, be shared between local powerbrokers, Egyptian military establishments, and representatives of affiliated temples in Egypt. Evidence suggests that divine estates--whether purchased by Egyptians, granted by friendly kings, or usurped by rights of conquest--frequently supported the costs of military occupation. In areas of the empire where divine estates funneled taxes to Egyptian bases, the custom of having locals deliver a portion of their produce to the temple of a god that they viewed as potentially effective on their behalf was likely held to be ideologically more palatable than would be a simple, unmasked extraction.

description: Let $X_1, ..., X_m$ be a set of $m$ statistically dependent sources over the common alphabet $\mathbb{F}_q$, that are linearly independent when considered as functions over the sample space. We consider a distributed function computation setting in which the receiver is interested in the lossless computation of the elements of an $s$-dimensional subspace $W$ spanned by the elements of the row vector $[X_1, \ldots, X_m]Γ$ in which the $(m \times s)$ matrix $Γ$ has rank $s$. A sequence of three increasingly refined approaches is presented, all based on linear encoders. The first approach uses a common matrix to encode all the sources and a Korner-Marton like receiver to directly compute $W$. The second improves upon the first by showing that it is often more efficient to compute a carefully chosen superspace $U$ of $W$. The superspace is identified by showing that the joint distribution of the $\{X_i\}$ induces a unique decomposition of the set of all linear combinations of the $\{X_i\}$, into a chain of subspaces identified by a normalized measure of entropy. This subspace chain also suggests a third approach, one that employs nested codes. For any joint distribution of the $\{X_i\}$ and any $W$, the sum-rate of the nested code approach is no larger than that under the Slepian-Wolf (SW) approach. Under the SW approach, $W$ is computed by first recovering each of the $\{X_i\}$. For a large class of joint distributions and subspaces $W$, the nested code approach is shown to improve upon SW. Additionally, a class of source distributions and subspaces are identified, for which the nested-code approach is sum-rate optimal.

description: The middle-aged PSR J0357+3205 is a nearby, radio-quiet, bright gamma-ray pulsar discovered by the Fermi mission. Our previous Chandra observation revealed a huge, very peculiar structure of diffuse X-ray emission, originating at the pulsar position and extending for > 9' on the plane of the sky. To better understand the nature of such a nebula, we have studied the proper motion of the parent pulsar. We performed relative astrometry on Chandra images of the field spanning a time baseline of 2.2 yr, unveiling a significant angular displacement of the pulsar counterpart, corresponding to a proper motion of 0.165"+/-0.030" yr^(-1). At a distance of ~500 pc, the space velocity of the pulsar would be of ~390 km s^(-1) assuming no inclination with respect to the plane of the sky. The direction of the pulsar proper motion is perfectly aligned with the main axis of the X-ray nebula, pointing to a physical, yet elusive link between the nebula and the pulsar space velocity. No optical emission in the H_alpha line is seen in a deep image collected at the Gemini telescope, which implies that the interstellar medium into which the pulsar is moving is fully ionized.

description: This paper considers the sum rate maximization problem of a two-user multiple-input single-output interference channel with receivers that can scavenge energy from the radio signals transmitted by the transmitters. We first study the optimal transmission strategy for an ideal scenario where the two receivers can simultaneously decode the information signal and harvest energy. Then, considering the limitations of the current circuit technology, we propose two practical schemes based on TDMA, where, at each time slot, the receiver either operates in the energy harvesting mode or in the information detection mode. Optimal transmission strategies for the two practical schemes are respectively investigated. Simulation results show that the three schemes exhibit interesting tradeoff between achievable sum rate and energy harvesting requirement, and do not dominate each other in terms of maximum achievable sum rate.

It is shown that in contrast to discrete graphs connection between the connectivity and the spectral gap is not one-to-one. The size of the spectral gap depends not only on the topology of the metric graph but on its geometric properties as well. It is shown that adding sufficiently large edges as well as cutting away sufficiently small edges leads to a decrease of the spectral gap. Corresponding explicit criteria are given.

description: Several attempts have been made to develop targeted therapies for malignant mesothelioma (MM), an aggressive tumour with a poor prognosis. In this study we evaluated whether Curcumin (CUR) potentiated the antitumor activity of the ErbB receptors inhibitor Afatinib (AFA) on MM, employing cell lines cultured in vitro and mice bearing intraperitoneally transplanted, syngeneic MM cells. The rationale behind this hypothesis was that CUR could counteract mechanisms of acquired resistance to AFA. We analysed CUR and AFA effects on MM cell growth, cell cycle, autophagy, and on the modulation of tumour-supporting signalling pathways. This study demonstrated that, as compared to the individual compounds, the combination of AFA + CUR had a stronger effect on MM progression which can be ascribed either to increased tumour cell growth inhibition or to an enhanced pro-apoptotic effect. These results warrant future studies aimed at further exploring the therapeutic potential of AFA + CUR-based combination regimens for MM treatment.

description: Several studies have suggested that betaine is closely related to inflammatory biomarkers that contribute to the development of metabolic diseases, but the effect remains controversial. This meta-analysis aimed to assess the effects of betaine supplementation on inflammatory markers based on randomised controlled trials (RCTs). PubMed, Web of Science and ResearchGate databases were searched up to March 2023. A total of 6 RCTs with 7 intervention trials involving 277 participants were included. Betaine supplementation led to a slight reduction in levels of circulating IL-1β of 0.65 pg/mL (95% CI, −1.23 to −0.06) with high heterogeneity (I2 = 95%). Betaine produced a small but nonsignificant reduction in levels of circulating CRP (0.33 mg/L; 95% CI, −1.79 to 1.14), IL-6 (0.47 pg/mL; 95% CI, −1.13 to 0.18) and TNF-α (0.25 pg/mL; 95% CI, −0.98 to 0.48). The present meta-analysis does not provide sufficient evidence to conclude that betaine supplementation improved the inflammation state.

description: In recent years, industrialization and urbanization have increased the emissions of volatile organic compounds (VOCs). The term "VOCs" refers to carbon-based chemicals exhibiting a significant vapor pressure at ambient conditions. In addition to causing air pollution, VOCs can also threaten human health. Among the available technologies for mitigating VOC emissions, catalytic oxidation stands out as a promising solution.
 A deep understanding of oxidation mechanism via fundamental kinetic modeling will allow exploiting the synergies between the catalytic material and operating conditions, aiming to develop optimal technologies for the abatement of VOCs. In general, deep catalytic oxidations of VOCs are explained by three models, namely the Langmuir− Hinshelwood (L-H), Eley−Rideal (E-R), and Mars−van Krevelen (MVK) models. In addition, a power law kinetic model can be employed as the first approach for further selection among the mentioned mechanistic models.
 In this work, methane was chosen as a VOC model compound to investigate its kinetic behavior over βcyclodextrin-Cu/hydroxyapatite (βCd-Cu/HAP), applying a power-low approach. The temperature (350 – 450 °C), inlet partial pressures (CH4:2.9 – 8 kPa, O2: 16 – 48 kPa), and spacetime (150 – 550 kgcat s molCH4,0) were varied to investigate the impact of operating conditions on reaction performance. The kinetic parameters were obtained using the power law model as a first step to finding the best mechanism for the deep oxidation of methane over the tested conditions. The optimized reaction orders for methane (0.6) and oxygen (0.1) showed that methane oxidation depends less on gas-phase oxygen, meaning that oxygen contained inside the catalyst plays a larger role. The power-law model parameters also helped to eliminate 27 models (out of 69) and identify LH and MVK as possible mechanisms.
Anomalous metallic state and anisotropic multiband superconductivity in Nb3Pd0.7Se7

description: We report the discovery of superconductivity in Nb$_3$Pd$_{x}$Se$_7$ with a $x$-dependent superconducting transition-temperature as high as $T_c \simeq 2.1 $ K for $x \simeq0.7$ (middle point of the resistive transition). Needle-like single crystals display anisotropic upper-critical fields with an anisotropy $γ= H^{b}_{c2}/H^{a}_{c2}$ as large as 6 between fields applied along their needle axis (or $b-$axis) or along the $a-$axis. As for the Fe based superconductors $γ$ is temperature-dependent suggesting that Nb$_3$Pd$_{0.7}$Se$_7$ is a multi-band superconductor. This is supported by band structure calculations which reveal a Fermi surface composed of quasi-one-dimensional and quasi-two-dimensional sheets of hole character, as well as three-dimensional sheets of both hole- and electron-character. Remarkably, $H^{b}_{c2}$ is observed to saturate at $H^{b}_{c2}(T \rightarrow 0 \text{K}) \simeq 14.1$ T which is $4.26 \times H_p$ where $H_p$ is the Pauli-limiting field in the weak-coupling regime. The synthesis procedure yields additional crystals belonging to the Nb$_2$Pd$_{x}$Se$_5$ phase which also becomes superconducting when the fraction of Pd is varied. For both phases we find that superconductivity condenses out of an anomalous metallic state, i.e. displaying $\partial ρ/ \partial T < 0$ above $T_c$ similarly to what is observed in the pseudogap-phase of the underdoped cuprates. An anomalous metallic state, low-dimensionality, multi-band character, extremely high and anisotropic $H_{c2}$s, are all ingredients for unconventional superconductivity.

description: We have computed low-mass stellar models and synthetic spectra for an initial chemical composition that includes the full C-N, O-Na, and Mg-Al abundance anticorrelations observed in second generation stars belonging to a number of massive Galactic globular clusters. This investigation extends a previous study that has addressed the effect of only the C-N and O-Na anticorrelations, seen in all globulars observed to date. We find that the impact of Mg-Al abundance variations at fixed [Fe/H] and Helium abundance is negligible on stellar models and isochrones (from the main sequence to the tip of the red giant branch) and bolometric corrections, when compared to the effect of C-N and O-Na variations. We identify a spectral feature at 490-520 nm, for low-mass main sequence stars, caused by MgH molecular bands. This feature has a vanishingly small effect on bolometric corrections for Johnson and Stroemgren filters that cover that spectral range. However, specific narrow-band filters able to target this wavelength region can be powerful tools to investigate the Mg-poor unevolved stars and highlight possible splittings of the MS due to variations of Mg abundances.

A generalization of this equation is proposed and studied via group analysis methods. The complete group classification of this generalized Kuramoto-Sivashinsky equation is carried out, it is classified according to the property of the self-adjointness and the corresponding conservation laws are established.

description: The noncommutative standard model apparently violates the Lorentz symmetry. We compare the Lorentz violating terms in the Higgs sector of the noncommutative standard model with their counterparts in the standard model extension. We show that the Lorentz violating parameters in the Higgs sector can be expressed directly in terms of the noncommutative parameter without any background field. The absence of the background field enhances the obtained bounds on the noncommutative parameter from the standard model extension.

description: We investigate characteristic features of realistic parameter choice for primordial inflation with supersymmetric Higgs inflaton as an example of particle physics inflation model. We discuss constraints from observational results and analyze the degree of fine tuning needed to induce slow-roll inflation for wide range of soft supersymmetry breaking scale. The observed amplitude of density fluctuations implies that the minimal fine tuning for the combined electroweak scale and inflaton flatness predicts the spectral index of 0.950--0.965, which includes the central value from observational data.

description: Originally proposed by Read [1] and Jain [2], the so-called "composite-fermion" is a phenomenological attachment of two infinitely thin local flux quanta seen as nonlocal vortices to two-dimensional (2D) electrons embedded in a strong orthogonal magnetic field. In this letter, it is described as a highly-nonlinear and coherent mean-field quantum process of the soliton type by use of a 2D stationary Schroedinger-Poisson differential model with only two Coulomb-interacting electrons. At filling factor $ν={1}{3}$ of the lowest Landau level, it agrees with both the exact two-electron antisymmetric Schroedinger wave function and Laughlin's Jastrow-type guess for the fractional quantum Hall effect, hence providing this later with a tentative physical justification based on first principles.

description: Chiral magnets, such as MnSi, display a rich finite temperature phase diagram in an applied magnetic field. The most unusual of the phases encountered is the so called A-phase characterized by a triangular lattice of skyrmion tubes. Its existence cannot be captured within a mean-field treatment of a Landau-Ginzburg functional but thermal fluctuations to Gaussian order are required to stabilize it. In this note we go beyond Gaussian order in a fully non-perturbative study of a three dimensional lattice spin model using classical Monte Carlo simulations. We demonstrate that the A-phase is indeed stabilized by thermal fluctuations and furthermore we reproduce the full phase diagram found in experiment. The thermodynamic signatures of the helimagnetic transition upon cooling from the paramagnet are qualitatively consistent with experimental findings and lend further support to the Brazovskii scenario which describes a fluctuation driven first order transition due to the abundance of soft modes.

description: We analyze an inflationary model in which part of the power in density perturbations arises due to particle production. The amount of particle production is modulated by an auxiliary field. Given an initial gradient for the auxiliary field, this model produces a hemispherical power asymmetry and a suppression of power at low multipoles similar to those observed by WMAP and Planck in the CMB temperature. It also predicts an additive contribution to $δT$ with support only at very small $l$ that is aligned with the direction of the power asymmetry and has a definite sign, as well as small oscillations in the power spectrum at all $l$.

This bean leafroller is distributed from Africa, India, and Ceylon to Burma, Andamans, Sumatra, Java, Celebes, Formosa, Fiji, Society Islands, Austral Islands, and Samoa. It does not seem to have been previously recorded in Guam. We found it quite common, and bean leaves were often copsiderably injured by its caterpillars. Our specimens were reared mainly from pole beans, also from pigeon pea and Flemingia strobilifera. A few moths were taken at light.
