description: In this paper, we propose an opportunistic network coding (ONC) scheme in cellular relay networks, which operates depending on whether the relay decodes source messages successfully or not. A fully distributed method is presented to implement the proposed opportunistic network coding scheme without the need of any feedback between two network nodes. We consider the use of proposed ONC for cellular downlink transmissions and derive its closed-form outage probability expression considering cochannel interference in a Rayleigh fading environment. Numerical results show that the proposed ONC scheme outperforms the traditional non-cooperation in terms of outage probability. We also develop the diversity-multiplexing tradeoff (DMT) of proposed ONC and show that the ONC scheme obtains the full diversity and an increased multiplexing gain as compared with the conventional cooperation protocols.

description: In this study, we investigate the spin susceptibility in the superconducting state of a multilayer system with a layer-dependent Rashba spin-orbit coupling, representing a locally non-centrosymmetric superconductor. We show that the charge imbalance between different layers yields a strong layer dependence on the susceptibility, most significantly for a weak spin-orbit coupling, which is in contrast to a situation with an equally distributed charge. These results can be relevant for experimental test in multilayer high-Tc cuprates as well as in superconducting CeCoIn5/YbCoIn5 superlattices with more than two layers.

description: In order to fully understand nanoscale heat transport it is necessary to spectrally characterize phonon transmission in nanostructures. Towards this goal we have developed a microfabricated phonon spectrometer. We utilize microfabricated superconducting tunnel junction-based (STJ) phonon transducers for the emission and detection of tunable, non-thermal, and spectrally resolved acoustic phonons, with frequencies ranging from ~100 to ~870 GHz, in silicon microstructures. We show that phonon spectroscopy with STJs offers a spectral resolution of ~15-20 GHz, which is ~20 times better than thermal conductance measurements, for probing nanoscale phonon transport. The STJs are Al-AlxOy-Al tunnel junctions and phonon emission and detection occurs via quasiparticle excitation and decay transitions that occur in the superconducting films. We elaborate on the design geometry and constraints of the spectrometer, the fabrication techniques, and the low-noise instrumentation that are essential for successful application of this technique for nanoscale phonon studies. We discuss the spectral distribution of phonons emitted by an STJ emitter and the efficiency of their detection by an STJ detector. We demonstrate that the phonons propagate ballistically through a silicon microstructure, and that submicron spatial resolution is realizable in a design such as ours. Spectrally resolved measurements of phonon transport in nanoscale structures and nanomaterials will further the engineering and exploitation of phonons, and thus have important ramifications for nanoscale thermal transport as well as the burgeoning field of nanophononics.

description: We use previously published high-resolution synchrotron polarization data to perform an angular dispersion analysis with the aim of charactering magnetized turbulence in M51. We first analyze three distinct regions (the center of the galaxy, and the northwest and southwest spiral arms) and can clearly discern the turbulent correlation length scale from the width of the magnetized turbulent correlation function for two regions and detect the imprint of anisotropy in the turbulence for all three. Furthermore, analyzing the galaxy as a whole allows us to determine a two-dimensional Gaussian model for the magnetized turbulence in M51. We measure the turbulent correlation scales parallel and perpendicular to the local mean magnetic field to be, respectively, delta_{para} = 98 +/- 5 pc and delta_{perp} = 54 +/- 3 pc, while the turbulent to ordered magnetic field strength ratio is found to be Bt/B0 = 1.01 +/- 0.04. These results are consistent with those of Fletcher et al. (2011), who performed a Faraday rotation dispersion analysis of the same data, and our detection of anisotropy is consistent with current magnetized turbulence theories.

Further Evidence for the Accretion Disk Origination of the Double-Peaked Broad H$α$ of 3C390.3

description: In the letter, under the widely accepted theoretical accretion disk model for the double-peaked emitter 3C390.3, the extended disk-like BLR can be well split into ten rings, and then the time lags between the lines from the rings and the continuum emission are estimated, based on the observed spectra around 1995. We can find one much strong correlation between the determined time lags (in unit of light-day) and the flux weighted radii (in unit of ${\rm R_G}$) of the rings, which is well consistent with the expected results through the theoretical accretion disk model. Moreover, through the strong correlation, the black hole masses of 3C390.3 are independently estimated as $\sim10^9{\rm M_{\odot}}$, the same as the reported black hole masses in the literature. The consistencies provide further evidence to strongly support the accretion disk origination of the double-peaked broad balmer lines of 3C390.3.

description: We develop an experimental scheme based on a continuous-wave (cw) laser for generating arbitrary superpositions of photon number states. In this experiment, we successfully generate superposition states of zero to three photons, namely advanced versions of superpositions of two and three coherent states. They are fully compatible with developed quantum teleportation and measurement-based quantum operations with cw lasers. Due to achieved high detection efficiency, we observe, without any loss correction, multiple areas of negativity of Wigner function, which confirm strongly nonclassical nature of the generated states.

Our device consists of concentric wrinkle rings on a gold-PDMS bilayer membrane, which converts collimated illuminations to diffraction-free focused beams. Beam diameters of 300-400 μm have been observed in the visible range. By comparing the theoretically calculated and experimentally measured focal spot profiles, we predict a focal spot size as small as around 50 μm if fabrication eccentricity can be eliminated.

description: We study necessary and sufficient conditions for a valued field $\KF$ with value group $G$ and residue field $\kf$ (with char $\KF$ = char $\kf$) to admit a truncation closed embedding in the field of generalized power series $\kf((G, f))$ (with factor set $f$). We show that this is equivalent to the existence of a family ({\it tower of complements}) of $\kf$-subspaces of $\KF$ which are complements of the (possibly fractional) ideals of the valuation ring. If $\KF$ is a Henselian field of characteristic 0 or, more generally, an algebraically maximal Kaplansky field, we give an intrinsic construction of such a family which does not rely on a given truncation closed embedding. We also show that towers of complements and truncation closed embeddings can be extended from an arbitrary field to at least one of its maximal immediate extensions.

description: The Electron Beam Freeform Fabrication (EBF3 ) System is a material depositing, layer additive technique that produces three dimensional (3D) parts out of a wide range of metals in high vacuum, using an electron beam and wire feedstock. Screening deposition trials on a titanium alloy, Ti-6Al-4V, at the National Aeronautics Space Administration (NASA) revealed selective vaporization of the aluminum content of linear prototypes when subjected to chemical analysis. In this study, the aluminum content, bead height and bead width output responses were analyzed from a systematic study of the effects that the interactions of the EBF3 processing parameters had on the finished parts. Results were derived from mathematical models (equations) using regression and the Analysis of Variance (ANOVA) statistics. These models were used to predict the optimum values of the processing parameters to promote the maximum aluminum content and optimal bead geometry to support future validation experiments. Optimization of EBF3 processing is vital to realizing the vision of manufacturing high quality and reliable replacement parts for space transportation.

description: The Lee-Wick Standard Model at temperatures near electroweak scale is considered, with the aim of studying the electroweak phase transition. While Lee-Wick theories possess states of negative norm, they are not pathological but instead are treated by imposing particular boundary conditions and using particular integration contours in the calculation of S-matrix elements. It is not immediately clear how to extend this prescription to formulate the theory at finite temperature; we explore two different pictures of finite-temperature LW theories, and calculate the thermodynamic variables and the (one-loop) thermal effective potential. We apply these results to study the Lee-Wick Standard Model and find that the electroweak phase transition is a continuous crossover, much like in the Standard Model. However, the high-temperature behavior is modified due to cancellations between thermal corrections arising from the negative- and positive-norm states.

description: Even though the ACL2 logic is first order, the ACL2 system offers several mechanisms providing users with some operations akin to higher order logic ones. In this paper, we propose a macro, named instance-of-defspec, to ease the reuse of abstract functions and facts proven about them. Defspec is an ACL2 book allowing users to define constrained functions and their associated properties. It contains macros facilitating the definition of such abstract specifications and instances thereof. Currently, lemmas and theorems derived from these abstract functions are not automatically instantiated. This is exactly the purpose of our new macro. instance-of-defspec will not only instantiate functions and theorems within a specification but also many more functions and theorems built on top of the specification. As a working example, we describe various fold functions over monoids, which we gradually built from arbitrary functions.

description: Ο καφές αποτελεί ένα από τα πλέον προσφιλή ροφήματα παγκοσμίως και αυτό δικαιολογεί, σε μεγάλο βαθμό, το γεγονός ότι βρίσκεται στο επίκεντρο του επιστημονικού ενδιαφέροντος εδώ και πολλές δεκαετίες. Η κατά κεφαλή κατανάλωση ροφημάτων καφέ σημειώνει αύξηση κάθε χρόνο και, σύμφωνα με τα διαθέσιμα στοιχεία, τα πρωτεία έχουν η Φινλανδία, η Νορβηγία και η Ισλανδία, ακολουθούμενες από τη Δανία, την Ολλανδία και τη Σουηδία. Η οικονομική και εμπορική σημασία του καφέ είναι πολύ μεγάλη, καθώς αποτελεί το σημαντικότερο γεωργικό εμπόρευμα, μετά το πετρέλαιο. Η δημοτικότητα του καφέ οφείλεται κυρίως στα μοναδικά οργανοληπτικά χαρακτηριστικά, αλλά και στην ήπια διεγερτική δράση του ροφήματος που αποδίδεται στην παρουσία καφεΐνης και παρόμοιων ενώσεων. Ο καφές παράγεται από τα σπέρματα καφεόδεντρων που ανήκουν στο γένος Coffea της οικογένειας Rubiaceae, μιας από τις μεγαλύτερες οικογένειες ανθοφόρων φυτών, με 500 περίπου γένη και 6.000 είδη. Από το σύνολο των διαφορετικών ειδών, πλέον σημαντικά από οικονομική άποψη είναι τα Coffea arabica L., και Coffea canephora var. robusta. Η μοναδική ταυτότητα των διαφορετικών ποικιλιών καφέ αρχίζει να διαμορφώνεται κατά την ανάπτυξη του φυτού, καθώς και στη διάρκεια των μετασυλλεκτικών χειρισμών και των διαδικασιών που έπονται της συγκομιδής των καρπών. Περιβαλλοντικοί παράγοντες, όπως η γεωγραφική προέλευση, το κλίμα, το υψόμετρο, η θερμοκρασία και η θρέψη του φυτού, επηρεάζουν σημαντικά την ποιότητα του καφέ. Ιδιαίτερα καθοριστική θεωρείται επίσης η δράση ενζύμων σε συστατικά των σπερμάτων, όπως οι πρωτεΐνες, οι υδατάνθρακες και οι φαινολικές ενώσεις. Σημαντικό ρόλο στη διαδικασία αυτή διαδραματίζουν μικροοργανισμοί (ζύμες, βακτήρια, μύκητες), οι οποίοι παράγουν πληθώρα μεταβολικών προϊόντων, κυρίως αλκοόλες και οξέα. Ο χαρακτήρας του καφέ τροποποιείται περαιτέρω κατά τη φρύξη (καβούρδισμα), στη διάρκεια της οποίας κυριαρχούν αντιδράσεις Maillard, οδηγώντας στην παραγωγή αρωματικών και γευστικών ενώσεων. Τα αρωματικά συστατικά που παράγονται κατά το καβούρδισμα συνιστούν, χωρίς αμφιβολία, τον πιο καθοριστικό παράγοντα της ποιότητας του καφέ. Οι πτητικές ενώσεις χαρακτηρίζουν όχι μόνο τις διαφορετικές ποικιλίες, αλλά και τη γεωγραφική προέλευση του καφέ. Μέχρι σήμερα, έχουν προσδιοριστεί περισσότερα από 1.000 πτητικά συστατικά. Εντούτοις, λίγα εξ αυτών φαίνεται να είναι σημαντικά για το άρωμα και τη γεύση του καφέ. Σύμφωνα με ορισμένους ερευνητές, το ιδιάζον άρωμα ενός τύπου καφέ διαμορφώνεται, ως επί το πλείστον, από μια ομάδα 20-30 μεμονωμένων πτητικών συστατικών

description: We propose a modification of a recently introduced generalized translation operator, by including a $q$-exponential factor, which implies in the definition of a Hermitian deformed linear momentum operator $\hat{p}_q$, and its canonically conjugate deformed position operator $\hat{x}_q$. A canonical transformation leads the Hamiltonian of a position-dependent mass particle to another Hamiltonian of a particle with constant mass in a conservative force field of a deformed phase space. The equation of motion for the classical phase space may be expressed in terms of the generalized dual $q$-derivative. A position-dependent mass confined in an infinite square potential well is shown as an instance. Uncertainty and correspondence principles are analyzed.

The Palaeolithic Discoveries from Mitoc - Malu Galben (Romania). The Aurignacian I and I Inferior Layers
Creators: name: Chirica, Vasile
name: Vornicu, Diana-Măriuca
Publisher: name: Arheologia Moldovei
Year: 2017

description: The paper makes a presentation of the two oldest archaeological layers at the Upper Palaeolithic site of Mitoc -Malu Galben: the Aurignacian I and Iinferior assemblages. The study provides ageographic andgeologic characterization of the area, by pointing out that the main reason for the prehistoric human communities to install their encampments here was the availability of the rich flint resources. The pedo-sedimentary stratigraphy of the site is also presented along with the distribution of the archaeological layers in the sedimentary units and the established climatic cycles. Among the Aurignacian layers, the Aurignacian I (subunit 10b inferior - 11 superior) provided the richest archaeological material: flint workshops concentrated around hearths, faunal remains and hard animal tissue artefacts (Mladec spearheads). The lithic typology is specific to the classical old Aurignacian (carenated endscrapers and burins, nosed endscrapers). The absolute chronology data indicate afirst occupation of the site around 32.730 ± 220 BP (Aurignacian I inferior - subunit 12 b) and the 30.000 BP for the end of the Aurignacian I occupation. The final part of the text propounds a framing of the Aurignacian discoveries from Malu Galben in the context of the Early Upper Palaeolithic from Europe.

Keywords: Early Upper Palaeolithic, Aurignacian, climatic cycles, technocomplexes, knapping workshops, combustion structures, paleo-environment, hard animal tissue artifacts.

description: We have analyzed long-slit spectra of 12 dwarf irregular galaxies from the Arecibo Dual Beam Survey (ADBS). These galaxies represent a heterogeneous sample of objects detected by ADBS, but on average are relatively gas-rich, low-surface-brightness, and low-mass, thus represent a region of the galaxian population that is not commonly included in optical surveys. The metallicity-luminosity relationship for these galaxies is analyzed; the galaxies discussed in this paper appear to be under-abundant at a given luminosity when compared to a sample from the literature. We attempt to identify a "second parameter" responsible for the intrinsic scatter and apparent under-abundance of our galaxies. We do not find a definitive second parameter but note the possible indication that infall or mixing of pristine gas may be responsible. We derive oxygen abundances for multiple HII regions in many of our galaxies but do not find any strong indications of metallicity variation within the galaxies except in one case where we see variation between an isolated HII region and the rest of the galaxy. Our data set includes the galaxy with the largest known HI-to-optical size ratio, ADBS 113845+2008. Our abundance analysis of this galaxy reveals that it is strongly over-enriched compared to galaxies of similar luminosity, indicating it is not a young object and confirming the result from Cannon et. al (2009) that this galaxy appears to be intrinsically rare in the local universe.

description: Objective: To examine the proportion of people with aphasia (PwA) included and retained in randomised controlled trials (RCTs) of stroke interventions published in the previous 6 years, as well as aphasia-relevant eligibility criteria and inclusion/retention strategies. Data sources: Comprehensive searching of Embase, PubMed and Medline (Ovid) for the period January 2016 – November 2022. Review methods: RCTs examining stroke interventions targeting cognition, psychological wellbeing/ health-related quality of life (HRQL), multidisciplinary rehabilitation, and self-management were included. Methodological quality was assessed using the Critical Appraisal Skills Programme (CASP) Randomised Controlled Trial checklist. Descriptive statistics were applied to extracted data, and results were reported narratively. Results: Fifty-seven RCTs were included. These examined self-management (32%), physical (26%) psychological wellbeing/HRQL (18%), cognitive (14%), and multidisciplinary (11%) interventions. Of 7313 participants, 107 (1.5%) had aphasia and were included in three trials. About one-third did not report on aphasia (32%); over one quarter required functional communication (28%); one quarter excluded all aphasia (25%); and 14% excluded severe aphasia. No aphasia-specific inclusion/retention strategies were available. Conclusion: The findings highlight ongoing under-representation. However, due to shortcomings in aphasia reporting, the findings may underestimate actual inclusion rate. Excluding PwA has implications for the external validity, effectiveness, and implementation of stroke research findings. Triallists may require support in aphasia research strategies and methodological reporting

description: In this work we present an inflationary mechanism based on fluid dynamics. Starting with the action for a single barotropic perfect fluid, we outline the procedure to calculate the power spectrum and the bispectrum of the curvature perturbation. It is shown that a perfect barotropic fluid naturally gives rise to a non-attractor inflationary universe in which the curvature perturbation is not frozen on super-horizon scales. We show that a scale-invariant power spectrum can be obtained with the local non-Gaussianity parameter $f_{NL}= 5/2$.

Gravitational Doppler and Level Relativity solved a discovered momentum paradox and identified the cause of relativity

description: We discovered how an inertial frame can be identified to be preferred over the other of being higher relativistic with respective to time dilation. Gravitons were identified as underlying a postulated Gravitational Doppler effect. It was found that a gravitational field of Gravitons is dynamically Doppler shifted. This enabled a generalization to identify static and dynamic gravitational fields to be equally responsible for all relativistic effects and therefore to be added by Gravitons in a proposed Gravitational Level model, a G-level, where every Inertial Frame does have its own summarized Gravitation Level and all relativistic effects are described by comparing them in the height of this level. This explains why it was true in Special Relativity the “moved clocks are slower” as a moved inertial frame has always a higher G-level by additionally Doppler shifting the resting one. A new discovered Momentum Paradox of Special Relativity, which contradicts irreparably the symmetric mass transformation, explained vividly in a be thought cosmic billiard game, was discovered and solved under Gravitational Level Model and a method to calculate the relativistic momentum using Lorentz transformations correctly only in a relativistically limited asymmetric way was introduced. Models of gravitative nature of the acceleration of solar wind particles and of the hot suns corona could be based on present hypothesis and an experiment was introduced to prove it. The dispute is guided in a vividly manner under using relativistic classic thought experiments and can be understood by anyone with an interest in relativistic physic science.

description: There is a growing interest in energy efficient or so-called "green" wireless communication to reduce the energy consumption in cellular networks. Since today's wireless terminals are typically equipped with multiple network access interfaces such as Bluetooth, Wi-Fi, and cellular networks, this paper investigates user terminals cooperating with each other in transmitting their data packets to a base station (BS) by exploiting the multiple network access interfaces, referred to as inter-network cooperation, to improve the energy efficiency in cellular uplink transmission. Given target outage probability and data rate requirements, we develop a closed-form expression of energy efficiency in Bits-per-Joule for the inter-network cooperation by taking into account the path loss, fading, and thermal noise effects. Numerical results show that when the cooperating users move towards to each other, the proposed inter-network cooperation significantly improves the energy efficiency as compared with the traditional non-cooperation and intra-network cooperation. This implies that given a certain amount of bits to be transmitted, the inter-network cooperation requires less energy than the traditional non-cooperation and intra-network cooperation, showing the energy saving benefit of inter-network cooperation.

description: It is shown that defining a suitable saturation momentum $Q_s$, the $p_T$ distributions of pp and AA collisions for any centrality and energy depend only on $τ=p^2_T/Q_s^2$ for $p_T1$, the higher the energy or the larger the size of the participant nuclei, the larger suppression present the respective spectra. The integrated spectrum gives a fraction of the hard multiplicity in the range from 9% for pp at 0.9 TeV to 2% for Pb-Pb central collisions at 2.76 TeV.

description: We present the analysis of the interrelation between two processes accounting for the spreading of an epidemics, and the information awareness to prevent its infection, on top of multiplex networks. This scenario is representative of an epidemic process spreading on a network of persistent real contacts, and a cyclic information awareness process diffusing in the network of virtual social contacts between the same individuals. The topology corresponds to a multiplex network where two diffusive processes are interacting affecting each other. The analysis using a Microscopic Markov Chain Approach (MMCA) reveals the phase diagram of the incidence of the epidemics and allows to capture the evolution of the epidemic threshold depending on the topological structure of the multiplex and the interrelation with the awareness process. Interestingly, the critical point for the onset of the epidemics has a critical value (meta-critical point) defined by the awareness dynamics and the topology of the virtual network, from which the onset increases and the epidemics incidence decreases.

Magnetic resonance modes above 50 K have been observed with an effective g-factor of 2.24 at 100 K. Below 30 K, intra-triplet excitations have been observed in the ESR spectra, which reveal the presence of single-ion anisotropy with D = -0.29 meV.

On the simultaneous evolution of massive protostars and their host cores

description: Studies of the evolution of massive protostars and the evolution of their host molecular cloud cores are commonly treated as separate problems. However, interdependencies between the two can be significant. Here, we study the simultaneous evolution of massive protostars and their host molecular cores using a multi-dimensional radiation hydrodynamics code that incorporates the effects of the thermal pressure and radiative acceleration feedback of the centrally forming protostar. The evolution of the massive protostar is computed simultaneously using the stellar evolution code STELLAR, modified to include the effects of variable accretion. The interdependencies are studied in three different collapse scenarios. For comparison, stellar evolutionary tracks at constant accretion rates and the evolution of the host cores using pre-computed stellar evolutionary tracks are computed. The resulting interdependencies of the protostellar evolution and the evolution of the environment are extremely diverse and depend on the order of events, in particular the time of circumstellar accretion disk formation with respect to the onset of the bloating phase of the star. Feedback mechanisms affect the instantaneous accretion rate and the protostar's radius, temperature and luminosity on timescales equal or smaller than 5 kyr, corresponding to the accretion timescale and Kelvin-Helmholtz contraction timescale, respectively. Nevertheless, it is possible to approximate the overall protostellar evolution in many cases by pre-computed stellar evolutionary tracks assuming appropriate constant average accretion rates.

description: We study deformations of three-dimensional large N CFTs by double-trace operators constructed from spin s single-trace operators of dimension Δ. These theories possess UV fixed points, and we calculate the change of the 3-sphere free energy δF= F_{UV}- F_{IR}. To describe the UV fixed point using the dual AdS_4 space we modify the boundary conditions on the spin s field in the bulk; this approach produces δF in agreement with the field theory calculations. If the spin s operator is a conserved current, then the fixed point is described by an induced parity invariant conformal spin s gauge theory. The low spin examples are QED_3 (s=1) and the 3-d induced conformal gravity (s=2). When the original CFT is that of N conformal complex scalar or fermion fields, the U(N) singlet sector of the induced 3-d gauge theory is dual to Vasiliev's theory in AdS_4 with alternate boundary conditions on the spin s massless gauge field. We test this correspondence by calculating the leading term in δF for large N. We show that the coefficient of (1/2)\log N in δF is equal to the number of spin s-1 gauge parameters that act trivially on the spin s gauge field. We discuss generalizations of these results to 3-d gauge theories including Chern-Simons terms and to theories where s is half-integer. We also argue that the Weyl anomaly a-coefficients of conformal spin s theories in even dimensions d, such as that of the Weyl-squared gravity in d=4, can be efficiently calculated using massless spin s fields in AdS_{d+1} with alternate boundary conditions. Using this method we derive a simple formula for the Weyl anomaly a-coefficients of the d=4 Fradkin-Tseytlin conformal higher-spin gauge fields. Similarly, using alternate boundary conditions in AdS_3 we reproduce the well-known central charge c=-26 of the bc ghosts in 2-d gravity, as well as its higher-spin generalizations.

description: Absorptive corrections, which are known to suppress proton-neutron transitions with a large fractional momentum z -> 1 in pp collisions, become dramatically strong on a nuclear target, and they push the partial cross sections of leading neutron production to the very periphery of the nucleus. The mechanism of the pion and axial vector a1-meson interference, which successfully explains the observed single-spin asymmetry in a polarized pp -> nX, is extended to the collisions of polarized protons with nuclei. When corrected for nuclear effects, it explains the observed single-spin azimuthal asymmetry of neutrons that is produced in inelastic events, which is where the nucleus violently breaks up. This single-spin asymmetry is found to be negative and nearly A-independent.
