description: We investigated Ce-substitution and reduction annealing effects on the electronic states at copper sites by Cu ${K}$-edge x-ray absorption near-edge structure measurements in Pr$_{2-x}$Ce$_x$CuO$_{4+α-δ}$ (PCCO) with varying $x$ and $δ$ (the amount of oxygen loss during annealing) values. Absorption near-edge spectra were modified by Ce-substitution and reduction annealing in a similar manner with increasing $x$ and $δ$. Considering electron doping by Ce-substitution, this similarity indicates an increase of electron number at the copper sites due to annealing $n_{\rm AN}$. Thus, the total number of electrons is determined by the amount of Ce and oxygen ions. Furthermore, quantitative analyses of the spectra clarified that the number of Cu$^+$ sites, corresponding to the induced electron number by Ce-substitution $n_{\rm Ce}$ increases linearly with $x$ in the as-sintered PCCO ($δ=0$), whereas $n_{\rm AN}$ is not exactly equal to twice of $δ$, which is expected from charge neutrality. For each $x$-fixed sample, $n_{\rm AN}$ tends to exceed 2$δ$ with increasing $δ$, suggesting the emergence of two types of carrier due to annealing.

description: The nanocrystalline TiO2 (nc TiO2 ) film was prepared by spraying pyrolysis method. Starting material for the synthesis was TiCl4 . Phase compositions and crystalline sizes were examined by pattern of XRD, and surface morphology of the thin film was analyzed by SEM and AFM. Optical characteristics were examined by UV – Vis and luminescent spectra (PL). Electric characteristics were examined by measuring resistance changing of films versus temperature. The experimental data showed that the forming films had nanostructure and typical photoelectric characteristics of nano TiO2 material which is similar to the ones prepared by other preparing methods. IF compared to others, this preparing method has such as simple equipments, inexpensive and available materials; so it is suitable for mass production.

description: This research work aimed to isolate and culture the bacterium Bacillus paramycoides for biogenic fabrication of zinc oxide nanoparticles, specifically ZnO and ZnO-ME nanoparticles (nanoparticles fabricated from bacterial extracts only – ZnO, and from bacterial cell mass including extract – ZnO-ME). SEM investigation revealed the spherical-shaped NPs with 22.33 and 39 nm in size for ZnO and ZnO-ME, respectively. The Brunauer, Emmett, and Teller (BET) studies revealed mesoporous structure with pore diameters of 13.839 and 13.88 nm and surface area of 7.617 and 33.635 m2/gm for ZnO and ZnO-ME, respectively. Various parameters for the adsorption of sulfur black dye onto both ZnO and ZnO-ME were screened and optimized using Plackett–Burman Design (PBD), Full Factorial Design (FFD) and Central Composite Design (CCD). The results of the optimization modeling study revealed that FFD yielded the most predictable and best-fitting results among all the models studied, with R2 values of 0.998 for ZnO and 0.993 for ZnO-ME. Notably, ZnO-ME exhibited a greater dye removal efficiency 80% than ZnO i.e., 71%, it may be due to the presence of amorphous carbon on the surface of ZnO-ME. Among the various isothermal models, the Freundlich model displayed the strongest correlation with the dye removal data, confirming the multilayer adsorption of dye on both nanoparticles and supporting physisorption. Therefore, ZnO and ZnO-ME nanoparticles have been proven as potential tools for mitigating environmental impacts associated with dye-containing wastewater.

description: The observed cosmic acceleration presents the physics and cosmology communities with amazing opportunities to make exciting, probably even radical advances in these fields. This topic is highly data driven and many of our opportunities depend on us undertaking an ambitious observational program. Here I outline the case for such a program based on both the exciting science related to the cosmic acceleration and the impressive impact that a strong observational program would have. Along the way, I challenge a number of arguments that skeptics use to question the value of a strong observational commitment to this field.

description: We consider a minimal model of a quantum rotator composed of a single particle confined in an harmonic potential and driven by two temperature-biased heat reservoirs. In the case the particle potential is rendered asymmetric and rotated an angle, a finite angular momentum develops, corresponding to a directed rotary motion. At variance with the classical case, the thermal fluctuations in the baths give rise to a non-vanishing average torque contribution; this is a genuine quantum effect akin to the Casimir effect. In the steady state the heat current flowing between the two baths is systematically converted into particle rotation. We derive exact expressions for the work rate and heat currents in the case where the system is driven by an external time periodic mechanical force. We show, in agreement with previous works on classical systems, that for this choice of external manipulation protocol, the rotator cannot work either as a heat pump or as a heat engine. We finally use our exact results to extend an ab-initio quantum simulation algorithm to the out-of-equilibrium regime.

description: GeTe is a well-known ferroelectric and thermoelectric material that undergoes a structural phase transition from a rhombohedral to the rocksalt structure at $\sim 600-700$ K. We present a first principles approach to calculate the thermal expansion of GeTe in the rhombohedral phase up to the Curie temperature. We find the minimum of the Helmholtz free energy with respect to each structural parameter in a manner similar to the traditional Gr{ü}neisen theory, and account for the temperature dependence of elastic constants. We obtain the temperature variation of the structural parameters of rhombohedral GeTe in very good agreement with experiments. In particular, we correctly reproduce a negative volumetric thermal expansion of GeTe near the phase transition. We show that the negative thermal expansion is induced by the coupling between acoustic and soft transverse optical phonons, which is also responsible for the low lattice thermal conductivity of GeTe.

We present a proper definition of the operators and study their properties, in particular, we show that the discrete spectrum can be empty if $Γ$ is short enough. If it is not the case, we investigate properties of the eigenvalues in the situation when the curve has a hiatus of length $2ε$. We derive an asymptotic expansion with the leading term which a multiple of $ε\lnε$.

Compact stars in Energy-Momentum Squared Gravity

description: A simple generalization to Einstein's general relativity (GR) was recently proposed which allows a correction term $T_{αβ}T^{αβ}$ in the action functional of the theory. This theory is called Energy-Momentum Squared Gravity (EMSG) and introduces a new coupling parameter $η$. EMSG resolves the big bang singularity and has a viable sequence of cosmological epochs in its thermal history. {Interestingly, in the vacuum EMSG is equivalent to GR, and its effects appear only inside the matter-energy distribution. More specifically, its consequences appear in high curvature regime. Therefore it is natural to expect deviations form GR inside compact stars. In order to study spherically symmetric compact stars in EMSG, we find the relativistic governing equations. More specifically, we find the generalized version of the Tolman-Oppenheimer-Volkov equation in EMSG. Finally we present two analytical solutions, and two numerical solutions for the field equations. For obtaining the numerical solutions we use polytropic equation of state which is widely used to understand the internal structure of neutron stars in the literature. Eventually we find a mass-radius relation for neutron stars. Also, We found that EMSG, depending on the central pressure of the star and the magnitude of free parameter $η$, can lead to larger or smaller masses for neutron stars compared with GR. Existence of high-mass neutron stars with ordinary polytropic equation of state in EMSG is important in the sense that these stars exist in GR provided that one use exotic equation of states.

description: We show theoretically that two-dimensional direct-gap semiconductors with a valley degree of freedom, including monolayer transition-metal dichalcogenides and gapped bilayer graphene, have a longitudinal magnetoconductivity contribution that is odd in valley and odd in the magnetic field applied perpendicular to the system. Using a quantum kinetic theory we show how this valley-dependent magnetoconductivity arises from the interplay between the momentum-space Berry curvature of Bloch electrons, the presence of a magnetic field, and disorder scattering. We discuss how the effect can be measured experimentally and used as a detector of valley polarization.

description: The contemporary superconductive electronics is widely using planar circuits with micrometer-scale elements for a variety of applications. With the rise of complexity of a circuit and increased number of its components, a simple impedance measurement are often not efficient for diagnostics of problems, nor for clarifying the physics underlying the circuit response. The established Scanning Laser Microscope (LSM) technique generates the micrometer-scale images of the amplitude of the microwave currents in a planar superconductive circuit, but not the phase of the oscillating currents. Here we present a novel, more powerful type of LSM imaging containing the signal phase information. We employ a fast optical modulator in order to synchronize the phase of the laser intensity oscillation with the phase of the probing microwave signal. The loss induced in laser illuminated area strongly depends on the phase difference between the RF probing signal and the laser beam modulation. We explain the detection principle of the phase sensitive LSM and experimentally demonstrate the capability of this method using superconductive microwave resonators. The described technique facilitates understanding of complex RF current distributions in superconductive circuits.

Both pure components undergo a reversible first order transformation to a high temperature phase. The mutual solubility of both components is unlimited in the orthorhombic room temperature phase. The maximum solubility of Lu in the high temperature phase of GdF3 (tysonite type) is about 20% and the maximum solubility of Gd in LuF3 ($α$-YF3 type) is about 40%. Intermediate compositions of the low temperature phase decompose upon heating in a peritectoid reaction to a mixture of both high temperature phases.

description: With the approach of exascale computing era, particle-based models are becoming the focus of research due to their excellent scalability. We present a new code, Slurm, which implements the classic particle-in-cell algorithm for modeling magnetized fluids and plasmas. It features particle volume evolution which damps the numerical finite grid instability, and allows modeling of key physical instabilities such as Kelvin-Helmholtz and Rayleigh-Taylor. The magnetic field in Slurm is handled via the electromagnetic vector potential carried by particles. Numerical diffusion of the magnetic flux is extremely low, and the solenoidality of the magnetic field is preserved to machine precision. A double-linked list is used to carry particles, thus implementation of open boundary conditions is simple and efficient. The code is written in C++ with OpenMP multi-threading, and has no external dependencies except for Boost. It is easy to install and use on multi-core desktop computers as well as on large shared-memory machines. Slurm is an ideal tool for its primary goal, modeling of space weather events in the heliosphere. This article walks the reader through the physical model, the algorithm, and all important details of implementation. Ideally, after finishing this paper, the reader should be able to either use Slurm for solving the desired problem, or create a new fluid PIC code.

description: We present results for the couplings of light vector mesons to vector and tensor currents and on the low moments of the light-cone distribution amplitudes of the pion and kaon. The calculations are performed on the RBC and UKQCD collaborations' ensembles generated with the Iwasaki gauge action and with 2+1 flavours of domain wall fermions. The (preliminary) results for the ratios of the couplings of the vector meson to the vector and tensor currents (f_V and f^T_V respectively) in the MSbar scheme at 2GeV are: f_ρ^T/f_ρ=0.681(20); f_{K^\ast}^T/f_{K^\ast}=0.712(11) and f_ϕ^T/f_ϕ=0.751(9). For the first moment of the kaon's distribution amplitude we find (in the same scheme and at the same scale) _K=0.029(2) and for the second moment _π=0.28(3) and _K=0.27(2).

description: Recent theories predict that discontinuous shear-thickening (DST) involves an instability, the nature of which remains elusive. Here, we explore unsteady dynamics in a dense cornstarch suspension by coupling long rheological measurements under constant shear stresses to ultrasound imaging. We demonstrate that unsteadiness in DST results from localized bands that travel along the vorticity direction with a specific signature on the global shear rate response. These propagating events coexist with quiescent phases for stresses slightly above DST onset, resulting in intermittent, turbulent-like dynamics. Deeper into DST, events proliferate, leading to simpler, Gaussian dynamics. We interpret our results in terms of unstable vorticity bands as inferred from recent model and numerical simulations.

In this paper, we pursue the latter possibility. We point out that dark radiation consisting of axion-like particles can resonantly convert into photons under the intergalactic magnetic field, which can effectively heat up the radiation in the frequency range relevant for the EDGES experiment. This may explain the EDGES anomaly.

description: Abstract

The Lungh Lake sanctuary is known for its avian diversity and full blossoming. In the present study, it was noted that wetlands consist of a number of avian fauna varieties. We detected various bird species, yet 53 types of birds were distinguished during field work; these birds had a location with 10 families; for example, Ardeidae, Rallidae, Charadridae, Alcedinidae, Sturnidae, Muscicapidae, Columbidae, Cuculidae, Anatidae, Recurvirostridae and Passeridae were recorded. High numbers of families were noted in Anatidae, and fewer species were Charadridae and Sturnidae. It was noted that a large number of families were migratory, and some were residents. These species, for the most part, depend upon water, in addition to the families Passeridae and Columbidae. Among the birds kept in this study, some were insectivores or grainivores; however, most of the overwhelming birds were piscivores.

Το επάγγελμα του εργοθεραπευτή καλείται να επιλύσει τα προβλήματα που προκαλεί η νόσος στο βαθμό που αυτά επηρεάζουν τη λειτουργικότητα του ατόμου στην καθημερινή του ζωή. Έχουν βρεθεί έρευνες και μελέτες που εξετάζουν τόσο τη μέτρηση της αναπηρίας που φέρνει η ασθένεια στον ασθενή, και ως εκ τούτου έχει ανάγκη εργοθεραπευτικές πρακτικές, όσο και την αποτελεσματικότητα των πρακτικών αυτών. Στην θεωρητική εργασία αυτή αναλύονται προηγούμενες έρευνες στις οποίες αρχικά κρίνεται η βάση της εργοθεραπευτικής πρακτικής για τον ασθενή. Βρέθηκε ότι ο ασθενής κατά την εξέλιξη της εκφυλιστικής αυτής νόσου αποκτά προβλήματα στη μυϊκή δύναμη τόσο στα άνω άκρα, όσο και στα κάτω. Στα κάτω άκρα αν και παρακολουθούν οι ασθενείς θεραπείες, αυτό γίνεται σε μικρό ποσοστό, αφού με το που χάσουν την ικανότητα βάδισης επαφίενται εντελώς στη χρήση αμαξιδίου. Στο άνω άκρο η εργοθεραπεία έχει περισσότερο πεδίο εργασιών, και σε πρακτικό επίπεδο οι εργοθεραπευτές ασχολούνται κυρίως με τη λεπτή κινητικότητα. Οι πιο ενδιαφέρουσες μελέτες που βρέθηκαν χρησιμοποιούν διάφορες δραστηριότητες θεραπευτικά μέσα. Οι κυριότερες από αυτές είναι η αναπνοή, η βάδιση στο επίπεδο που είναι δυνατόν, η παραγωγή μουσικών μελωδιών, η ιππασία, η αναρρίχηση, η άσκηση μέσα στο νερό, και η χρήση υποστηρικτικής τεχνολογίας. Τα αποτελέσματα της ανασκόπησης όλων αυτών των μελετών μας οδήγησε στο συμπέρασμα ότι η βέλτιστη μορφή θεραπείας για ένα άτομο με σκλήρυνση κατά πλάκας είναι τελικά η συνδυαστική προσέγγιση. Οι ειδικότητες της διεπιστημονικής ομάδας αρχικά πρέπει να συνεργαστούν για να βοηθηθεί ο ασθενής σε όλα τα επίπεδα. Όσον αφορά συγκεκριμένα την εργοθεραπευτική παρέμβαση, ισχύει επίσης ότι ο συνδυασμός διαφορετικών τεχνικών βελτιώνει και διαφορετικές ικανότητες του ατόμου. Συνεπώς, όλες οι παραπάνω πρακτικές πρέπει να συνδυαστούν για τη βελτίωση της λειτουργικότητα του ατόμου που πάσχει από τη νόσο αυτή.

description: Impurity scattering in the unitary limit produces low energy quasiparticles with anisotropic spectrum in a two-dimensional $d$-wave superconductor. We describe a new {\em quasi-one-dimensional } limit of the quasiparticle scattering, which might occur in a superconductor with short coherence length and with {\em finite} impurity potential range. The dc conductivity in a $d$-wave superconductor is predicted to be proportional to the normal state scattering rate and is impurity-{\em dependent}. We show that the {\em quasi-one-dimensional } regime occurs in high-$T_c$ superconductors at low temperatures $T\lesssim 10$~K. We argue that the impurities produce weak localization, in the {\em orthogonal } universality class, of the quasiparticles in a $d$-wave superconductor.

description: We explore in a parameterized manner a very large range of physically plausible equations of state (EOSs) for compact stars for matter that is either purely hadronic or that exhibits a phase transition. In particular, we produce two classes of EOSs with and without phase transitions, each containing one million EOSs. We then impose constraints on the maximum mass, ($M < 2.16 M_{\odot}$), and on the dimensionless tidal deformability ($\tildeΛ <800$) deduced from GW170817, together with recent suggestions of lower limits on $\tildeΛ$. Exploiting more than $10^9$ equilibrium models for each class of EOSs, we produce distribution functions of all the stellar properties and determine, among other quantities, the radius that is statistically most probable for any value of the stellar mass. In this way, we deduce that the radius of a purely hadronic neutron star with a representative mass of $1.4\,M_{\odot}$ is constrained to be $12.00\!\!375$, again at a $2$-$σ$ level. On the other hand, because EOSs with a phase transition allow for very compact stars on the so-called `twin-star' branch, small radii are possible with such EOSs although not probable, i.e. $8.53\!\!35.5$ at a $3$-$σ$ level. Finally, since these EOSs exhibit upper limits on $\tildeΛ$, the detection of a binary with total mass of $3.4\,M_{\odot}$ and $\tildeΛ_{1.7}\!>\!461$ can rule out twin-star solutions.

Quantization of a Theory of 2d Dilaton Gravity

description: We discuss the quantization of the 2d gravity theory of Callan, Giddings, Harvey, and Strominger (CGHS), following the procedure of David, and of Distler and Kawai. We find that the physics depends crucially on whether the number of matter fields is greater than or less than 24. In the latter case the singularity pointed out by several authors is absent but the physical interpretation is unclear. In the former case (the one studied by CGHS) the quantum theory which gives CGHS in the linear dilaton semi-classical limit, is different from that which gives CGHS in the extreme Liouville regime.

description: Abstract

In view of the huge untapped tourism potential of Kerala, often projected as ‘God’s own Country’ while marketing the State in the global canvass, this paper focuses on Responsible Tourism (RT) and the need to encourage RT sustainably for the rapid economic development of the State, given vast linkage effects of tourism with many other sectors, including the housing sector – another sector with maximum linkage effects. The need for taking extreme caution to preserve the natural environment and also the extensive use of ICT for environment-friendly and competitive promotion of tourism are highlighted in the paper.

description: In this paper we revisit the derivation of a nonlocal interfacial Hamiltonian model for systems with short-ranged intermolecular forces. Starting from a microscopic Landau-Ginzburg-Wilson Hamiltonian with a double parabola potential, we reformulate the derivation of the interfacial model using a rigorous boundary integral approach. This is done for three scenarios: a single fluid phase in contact with a nonplanar substrate (i.e., wall); a free interface separating coexisting fluid phases (say, liquid and gas); and finally a liquid-gas interface in contact with a nonplanar confining wall, as is applicable to wetting phenomena. For the first two cases our approaches identifies the correct form of the curvature corrections to the free energy and, for the case of a free interface, it allows us to recast these as an interfacial self-interaction as conjectured previously in the literature. When the interface is in contact with a substrate our approach similarly identifies curvature corrections to the nonlocal binding potential, describing the interaction of the interface and wall, for which we propose a generalized and improved diagrammatic formulation.

Μεσοθεραπεία

description: Η μεσοθεραπεία αποτελεί μια από τις δημοφιλείς μεθόδους που προσφέρει η σύγχρονη αισθητική για την αντιγήρανση, την ενυδάτωση και σύσφιξη του δέρματος, την μείωση της τοπικής συσσώρευσης λίπους και φυσικά ελαχιστοποίησης του δέρματος «δίκην φλοιού πορτοκαλιού». Η μεσοθεραπεία βρίσκει εφαρμογή και σε άλλες ενδείξεις οι οποίες αναφέρονται αναλυτικά στο αντίστοιχο κεφάλαιο. Η τεχνική της μεσοθεραπείας χαρακτηρίζεται από πολλαπλές μικροενέσεις με έγχυση διάφορων ουσιών όπως βιταμινών και άλλων βιοδραστικών εκδόχων στο δέρμα. Διακρίνεται σε δύο είδη την ενέσιμη και την μη ενέσιμη. Υπάρχουν όμως και άλλες τεχνικές που εφαρμόζονται και ανάλογα με τις ανάγκες κάθε ασθενούς, όπως η αυτόλογη μεσοθεραπεία. Η μέθοδος αυτή αποτελεί μια ιατρική πράξη χορήγησης φαρμάκων, φυτικών εκχυλισμάτων, ιχνοστοιχείων και άλλων ουσιών οι οποίες έχουν ξεχωριστή δράση και εφαρμόζονται ειδικά για κάθε περίπτωση. Σύμφωνα με τα βιβλιογραφικά δεδομένα, η μεσοθεραπεία μπορεί να είναι επιβοηθητική για τους ασθενείς, έχει όμως συσχετιστεί με την εμφάνιση τοπικών ή συστηματικών αντιδράσεων.

description: Transit timing variations (TTVs) are a powerful tool for characterizing the properties of transiting exoplanets. However, inferring planet properties from the observed timing variations is a challenging task, which is usually addressed by extensive numerical searches. We propose a new, computationally inexpensive method for inverting TTV signals in a planetary system of two transiting planets. To the lowest order in planetary masses and eccentricities, TTVs can be expressed as a linear combination of 3 functions, which we call the \textit{TTV modes}. These functions depend only on the planets' linear ephemerides, and can be either constructed analytically, or by performing 3 orbital integrations of the three-body system. Given a TTV signal, the underlying physical parameters are found by decomposing the data as a sum of the TTV modes. We demonstrate the use of this method by inferring the mass and eccentricity of 6 \textit{Kepler} planets that were previously characterized in other studies. Finally we discuss the implications and future prospects of our new method.

description: High-energy photons are a powerful probe for astrophysics and for fundamental physics under extreme conditions. During the recent years, our knowledge of the most violent phenomena in the Universe has impressively progressed thanks to the advent of new detectors for high-energy gamma-rays. Observation of gamma-rays gives an exciting view of the high-energy universe thanks to satellite-based telescopes (AGILE, GLAST) and to ground-based detectors like the Cherenkov telescopes (H.E.S.S. and MAGIC in particular), which recently discovered more than 60 new very-high-energy sources. The progress achieved with the last generation of Cherenkov telescopes is comparable to the one drawn by EGRET with respect to the previous gamma-ray satellite detectors. This article reviews the present status of high-energy gamma astrophysics, with emphasis on the recent results and on the experimental developments.

Low-Temperatures Vortex Dynamics in Twinned Superconductors

description: We discuss the low-temperature dynamics of magnetic flux lines in samples with a family of parallel twin planes. A current applied along the twin planes drives flux motion in the direction transverse to the planes and acts like an electric field applied to {\it one-dimensional} carriers in disordered semiconductors. As in flux arrays with columnar pins, there is a regime where the dynamics is dominated by superkink excitations that correspond to Mott variable range hopping (VRH) of carriers. In one dimension, however, rare events, such as large regions void of twin planes, can impede VRH and dominate transport in samples that are sufficiently long in the direction of flux motion. In short samples rare regions can be responsible for mesoscopic effects.

description: The Isospin Quantum Molecular Dynamics model is used to compare spectra and elliptic flow of kaons produced at subthreshold energies with data taken at the SIS accelerator at GSI. We find that temperatures of the spectra are dominated by the rescattering of the kaons. The study of elliptic flow observables indicates the influence of rescattering as well as of the optical potential of the kaons with increasing dominance of the optical potential at lower incident energies.

description: Temperature sensing with nitrogen vacancy (NV) centers using quantum techniques is very promising and further development is expected. Recently, the optically detected magnetic resonance (ODMR) spectrum of a high-density ensemble of the NV centers was reproduced with noise parameters [inhomogeneous magnetic field, inhomogeneous strain (electric field) distribution, and homogeneous broadening] of the NV center ensemble. In this study, we use ODMR to estimate the noise parameters of the NV centers in several diamonds. These parameters strongly depend on the spin concentration. This knowledge is then applied to theoretically predict the temperature sensitivity. Using the diffraction-limited volume of 0.1 micron^3, which is the typical limit in confocal microscopy, the optimal sensitivity is estimated to be around 0.76 mK/Hz^(1/2) with an NV center concentration of 5.0e10^17/cm^3. This sensitivity is much higher than previously reported sensitivities, demonstrating the excellent potential of temperature sensing with NV centers.
