Nuclear quantum effects in thermal conductivity from centroid molecular dynamics

description: We show that the centroid molecular dynamics (CMD) method provides a realistic way to calculate the thermal diffusivity $a=λ/ρc_{\rm V}$ of a quantum mechanical liquid such as para-hydrogen. Once $a$ has been calculated, the thermal conductivity can be obtained from $λ=ρc_{\rm V}a$, where $ρ$ is the density of the liquid and $c_{\rm V}$ is the constant-volume heat capacity. The use of this formula requires an accurate quantum mechanical heat capacity $c_{\rm V}$, which can be obtained from a path integral molecular dynamics simulation. The thermal diffusivity can be calculated either from the decay of the equilibrium density fluctuations in the liquid or by using the Green-Kubo relation to calculate the CMD approximation to $λ$ and then dividing this by the corresponding approximation to $ρc_{\rm V}$. We show that both approaches give the same results for liquid para-hydrogen and that these results are in good agreement with experimental measurements of the thermal conductivity over a wide temperature range. In particular, they correctly predict a decrease in the thermal conductivity at low temperatures -- an effect that stems from the decrease in the quantum mechanical heat capacity and has eluded previous para-hydrogen simulations. We also show that the method gives equally good agreement with experimental measurements for the thermal conductivity of normal liquid helium.

description: In the present paper we investigate the impact of the external noise and detection threshold level on the simulation data for the systems that evolve through metastable states. As a representative model of such systems we chose the nonequilibrium athermal random field Ising model with two types of the external noise, uniform white noise and Gaussian white noise with various different standard deviations, imposed on the original response signal obtained in model simulations. We applied a wide range of detection threshold levels in analysis of the signal and show how these quantities affect the values of exponent $γ_{S/T}$ (describing the scaling of the average avalanche size with duration), the shift of waiting time between the avalanches, and finally the collapses of the waiting time distributions. The results are obtained via extensive numerical simulations on the equilateral three-dimensional cubic lattices of various sizes and disorders.

description: The development of the phase-imaging ion-cyclotron resonance (PI-ICR) technique for use in Penning trap mass spectrometry (PTMS) increased the speed and precision with which PTMS experiments can be carried out. In PI-ICR, data sets of the locations of individual ion hits on a detector are created showing how ions cluster together into spots according to their cyclotron frequency. Ideal data sets would consist of a single, 2D-spherical spot with no other noise, but in practice data sets typically contain multiple spots, non-spherical spots, or significant noise, all of which can make determining the locations of spot centers non-trivial. A method for assigning groups of ions to their respective spots and determining the spot centers is therefore essential for further improving precision and confidence in PI-ICR experiments. We present the class of Gaussian mixture model (GMM) clustering algorithms as an optimal solution. We show that on simulated PI-ICR data, several types of GMM clustering algorithms perform better than other clustering algorithms over a variety of typical scenarios encountered in PI-ICR. The mass spectra of $^{163}\text{Gd}$, $^{163m}\text{Gd}$, $^{162}\text{Tb}$, and $^{162m}\text{Tb}$ measured using PI-ICR at the Canadian Penning trap mass spectrometer were checked using GMMs, producing results that were in close agreement with the previously published values.

Health and Economic Risk of COVID-19: It is About Quality of Life!

Publisher: name: Zenodo
Year: 2023

description: The argument of whether to continue the societal lockdown intended to reduce the spread of the COVID-19 infection, or progressively open communities and begin the process of recovery from the disastrous effects of the pandemic is not compatible with medically sound practices. The discussion should be centered on assessing the differential risk of increasing the spread of the infection with that of prolonging conditions of inadequate quality of life among all affected by the lockdown. The latter, hardly found in any of the prevailing narratives, is not factored in the highly polarized opinions expressed in the media. On one hand, once criteria for restoring some semblance of normalcy to everyday life became available, the governors of several states (notably Georgia and Tennessee) quickly began to outline the specific steps of their plans to reestablish many services, allowing many businesses to resume their customer interactions, suspended for the better part of the last quarter. Almost immediately, they were criticized by segments of their constituency, who argued that such plans were premature, irresponsible, risky, and wholly unjustified. Conversely, citizens of states such as Michigan and California publicly manifested their wish for their governors to loosen the yoke of mandates that prevented them from earning a living. Thus, the health risk of the infection became juxtaposed to the economic risk of maintaining the Spartan solutions intended to reduce the former.

description: We perform a detailed study of the phase transitions and mechanisms of electron localization in the extended Hubbard model using the dynamical cluster approximation on a $2\times 2$ cluster. We explore the interplay of charge order and Mott physics. We find that a nearest-neighbor Coulomb interaction $V$ causes "screening" effects close to the Mott phase transition, pushing the phase boundary to larger values of $U$. We also demonstrate the different effects of $V$ on correlations in metallic and insulating regimes and document the different correlation aspects of charge order and Mott states.

description: The boundary element method (BEM) enables solving three-dimensional electromagnetic problems using a two-dimensional surface mesh, making it appealing for applications ranging from electrical interconnect analysis to the design of metasurfaces. The BEM typically involves the electric and magnetic fields as unknown quantities. Formulations based on electromagnetic potentials rather than fields have garnered interest recently, for two main reasons: (a) they are inherently stable at low frequencies, unlike many field-based approaches, and (b) potentials provide a more direct interface to quantum physical phenomena. Existing potential-based formulations for electromagnetic scattering have been proposed primarily for perfect conductors. We develop a potential-based BEM formulation which can capture both dielectric and conductive losses, and accurately models the skin effect over broad ranges of frequency. The accuracy of the proposed formulation is validated through canonical and realistic numerical examples.

description: The localization of electrons in the field of isolated nonmagnetic impurity atoms on the surface of a nanotube in a magnetic field is considered. A model of a Gaussian separable impurity potential capable of localizing an electron at any intensity is used. The positions of the local level are found in the regime of strong and weak localizations. The positions of the resonances are found, their widths are estimated. They experience Aharonov-Bohm oscillations when the magnetic flux in the tube changes. It is shown that the positions of the resonances experience oscillations similar to the de Haas-van Alphen oscillations, which are not associated with a magnetic field.

Statistics of collision parameters computed from 2D simulations

Publisher: name: arXiv
Year: 2021
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: There are two popular ways to speed up simulations of planet formation via increasing the collision probability: ({\it i}) confine motion to 2D, ({\it ii}) artificially enhance the physical radii of the bodies by an expansion factor. In this paper I have performed 100 simulations each containing $10^4$ interacting bodies and computed the collision parameters from the results of the runs. Each run was executed for a lower and a higher accuracy parameter. The main goal is to determine the probability distribution functions of the collision parameters and their dependence on the expansion factor. A simple method is devised to improve the determination of the collision parameters from the simulation data. It was shown that the distribution of the impact parameter is uniform and independent of the expansion factor. For real collisions the impact velocity is greater than 1 mutual escape velocity, a finding that can be explained using the two-body problem. The results casts some doubts on simulations of the terrestrial planets' final accretion that have assumed merge. Collision outcome maps were created adopting the fragmentation model of \cite{Leinhardt2012} to estimate the number of different types of collisions. A detailed comparison with earlier works indicates that there are similarities as well as significant differences between the different works. The results indicate that as the planetary disc matures and the masses of the bodies differs progressively than the majority of collisions lead to mass growth either via partial accretion or via graze-and-merge collision.

description: We propose a projection approach to perform quantum Monte Carlo (QMC) simulation on the infinite-$U$ Hubbard model at some integer fillings where either it is sign problem free or surprisingly has an algebraic sign structure -- a power law dependence of average sign on system size. We demonstrate our scheme on the infinite-$U$ $SU(2N)$ fermionic Hubbard model on both a square and honeycomb lattice at half-filling, where it is sign problem free, and suggest possible correlated ground states. The method can be generalized to study certain extended Hubbard models applying to cluster Mott insulators or two-dimensional Moiré systems; among one of them at certain non-half-integer filling, the sign has an algebraic behavior such that it can be numerically solved within a polynomial time. Further, our projection scheme can also be generalized to implement the Gutzwiller projection to spin basis such that $SU(2N)$ quantum spin models and Kondo lattice models may be studied in the framework of fermionic QMC simulations.

description: Over the past decade, many approaches have been introduced for traffic speed prediction. However, providing fine-grained, accurate, time-efficient, and adaptive traffic speed prediction for a growing transportation network where the size of the network keeps increasing and new traffic detectors are constantly deployed has not been well studied. To address this issue, this paper presents DistTune based on Long Short-Term Memory (LSTM) and the Nelder-Mead method. Whenever encountering an unprocessed detector, DistTune decides if it should customize an LSTM model for this detector by comparing the detector with other processed detectors in terms of the normalized traffic speed patterns they have observed. If similarity is found, DistTune directly shares an existing LSTM model with this detector to achieve time-efficient processing. Otherwise, DistTune customizes an LSTM model for the detector to achieve fine-grained prediction. To make DistTune even more time-efficient, DistTune performs on a cluster of computing nodes in parallel. To achieve adaptive traffic speed prediction, DistTune also provides LSTM re-customization for detectors that suffer from unsatisfactory prediction accuracy due to for instance traffic speed pattern change. Extensive experiments based on traffic data collected from freeway I5-N in California are conducted to evaluate the performance of DistTune. The results demonstrate that DistTune provides fine-grained, accurate, time-efficient, and adaptive traffic speed prediction for a growing transportation network.

description: As the demand for machine learning-based inference increases in tandem with concerns about privacy, there is a growing recognition of the need for secure machine learning, in which secret models can be used to classify private data without the model or data being leaked. Fully Homomorphic Encryption (FHE) allows arbitrary computation to be done over encrypted data, providing an attractive approach to providing such secure inference. While such computation is often orders of magnitude slower than its plaintext counterpart, the ability of FHE cryptosystems to do \emph{ciphertext packing} -- that is, encrypting an entire vector of plaintexts such that operations are evaluated elementwise on the vector -- helps ameliorate this overhead, effectively creating a SIMD architecture where computation can be vectorized for more efficient evaluation. Most recent research in this area has targeted regular, easily vectorizable neural network models. Applying similar techniques to irregular ML models such as decision forests remains unexplored, due to their complex, hard-to-vectorize structures. In this paper we present COPSE, the first system that exploits ciphertext packing to perform decision-forest inference. COPSE consists of a staging compiler that automatically restructures and compiles decision forest models down to a new set of vectorizable primitives for secure inference. We find that COPSE's compiled models outperform the state of the art across a range of decision forest models, often by more than an order of magnitude, while still scaling well.

description: Spin-charge conversion by inverse spin Hall effect or inverse Rashba-Edelstein effect is prevalent in spintronics but dissipative. We propose a dissipationless spin-charge conversion mechanism by an excitonic pseudospin superfluid in an electron-hole double layer system. Magnetic exchange fields lift singlet-triplet degeneracy of interlayer exciton levels in the double layer system. Condensation of the singlet-triplet hybridized excitons breaks both a U(1) gauge symmetry and a pseudospin rotational symmetry around the fields, leading to spin-charge coupled superflow in the system. We demonstrate the mechanism by deriving spin-charge coupled Josephson equations for the excitonic superflow from a coupled quantum-dot model.

description: Conventional kinesin is a motor protein, which is able to walk along a microtubule processively. The exact mechanism of the stepping motion and force generation of kinesin is still far from clear. In this paper we argue that neck linker docking is a crucial element of this mechanism, without which the experimentally observed dwell times of the steps could not be explained under a wide range of loading forces. We also show that the experimental data impose very strict constraints on the lengths of both the neck linker and its docking section, which are compatible with the known structure of kinesin.

description: We study scattering of itinerant electrons off a magnetic hopfion in a three-dimensional metallic magnet described by a magnetization vector $\mathbf S(\mathbf r)$. A hopfion is a confined topological soliton of $\mathbf S(\mathbf r)$ characterized by an {\it emergent} magnetic field $B_γ(\mathbf r) \equiv ε_{αβγ} \,\mathbf S\cdot(\nabla_α\mathbf S\times \nabla_β\mathbf S)/4 \neq 0$ with vanishing average value $\langle \mathbf B(\mathbf r)\rangle = 0$. We evaluate the scattering amplitude in the opposite limits of large and small hopfion radius $R$ using the eikonal and Born approximations, respectively. In both limits, we find that the scattering cross-section contains a skew-scattering component giving rise to the Hall effect within a hopfion plane. That conclusion contests the popular notion that the topological Hall effect in non-collinear magnetic structures necessarily implies $\langle \mathbf B(\mathbf r)\rangle \neq 0$. In the limit of small hopfion radius $pR \ll 1$, we expand the Born series in powers of momentum $p$ and identify different expansion terms corresponding to the hopfion anisotropy, toroidal moment, and skew-scattering.

La revue de la littérature, permet de connaitre la réalité sur l’utilisation de l’énergie fossile et l’énergie renouvelable à Madagascar, encore faible. Nous avons utilisé les variables comme la production de l’énergie renouvelable, la croissance économique réelle, le salaire réel et la valeur ajoutée industrielle. Nous avons utilisé le modèle économétrique de cointégration, qui permet de connaître la cointégration et la entre ces variables du court terme et du long terme. Nous avons terminé sur l’analyse de réaction de choc impulsionnel. Nous pouvons conclure que la production de l’énergie renouvelable joue un rôle très important à la croissance économique, malgré que le domaine de l’énergie renouvelable est en progression à Madagascar. Ces quatre variables sont significativement cointégrées. Ainsi la corrélation entre la production de l’énergie renouvelable et celle de la production brute réelle est très remarquée par rapport aux autres variables, c'est-à-dire leur réaction des chocs impulsionnels est très forte.

description: There are only a few ``dark galaxy'' candidates discovered to date in the local Universe. One of the most prominent of them is the SW component of a merging system HI 1225+01. On the other hand, the number of known very metal-poor gas-rich dwarfs similar to IZw18 and SBS 0335-052 E,W has grown drastically during the last decade, from a dozen and a half to about five dozen. Many of them are very gas-rich, having from ~90 to 99% of all baryons in gas. For some of such objects that have the deep photometry data, no evidences for the light of old stars are found. At least a half of such galaxies with the prominent starbursts have various evidences of interactions, including advanced mergers. This suggests that a fraction of this group objects can be a kind of very stable protogalaxies (or ``dark galaxies''), which have recently experienced strong disturbances from nearby massive galaxy-size bodies. Such a collision caused the gas instabilities and its collapse with the subsequent onset of starburst. We briefly discuss the morphology and gas kinematics for the subsample of the most metal-poor dwarfs that illustrate this picture. We discuss also the relation of these rare galaxies to the processes by which ``dark galaxies'' can occasionally transform to optically visible galaxies.

description: Quantum Weak Energy Inequalities (QWEIs) are results which limit the extent to which the smeared renormalised energy density of a quantum field can be negative. On globally hyperbolic spacetimes the massive quantum Dirac field is known to obey a QWEI in terms of a reference state chosen arbitrarily from the class of Hadamard states; however, there exist spacetimes of interest on which state-dependent bounds cannot be evaluated. In this paper we prove the first QWEI for the massive quantum Dirac field on four dimensional globally hyperbolic spacetime in which the bound depends only on the local geometry; such a QWEI is known as an absolute QWEI.
Studio clinico e parassitologico di campo (FASEIII) per la valutazione di un prodotto vaccinale anti-Leishmania in cani naturalmente esposti.

description: Nell’ultimo decennio l’incidenza della leishmaniosi, sia nel cane che nell’uomo, è apparsa in
netto aumento.
L’attenzione degli studiosi che si interessano dell’argomento è oggi rivolta soprattutto
all’immunoterapia e alla profilassi vaccinale, senza naturalmente trascurare l’interessantissimo
filone di ricerca volto alla messa a punto di sostanze utilizzabili nei confronti dei flebotomi. Diversi
esperimenti vaccinali sono in corso in varie parti del mondo anche se, almeno per quanto riguarda la
specie canina, nonostante risultati sperimentali incoraggianti, non sono stati ancora messi a punto
dei protocolli utilizzabili nella pratica professionale. Le molecole di seconda generazione hanno
dato risultati soddisfacenti ponendo buone basi per le sperimentazioni future. Tra queste molecole il
“LiESAp”, addizionato con muramyl dipeptide (MDP) come adiuvante, ha prodotto risultati
soddisfacenti, tuttavia la bassa incidenza di malattia durante il periodo di sperimentazione pone in
dubbio la reale efficacia del vaccino. Proprio da quest’ultima considerazione prende corpo l’idea di
sperimentare un vaccino “analogo” al “LiESAp” in una zona del sud Italia ad endemia notoriamente
elevata: Santa Anastasia [prevalenza di leishmaniosi canina pari al 40,4% (Maroli et al., 2001)].
Lo studio ha lo scopo di verificare l’efficacia
protettiva di tale vaccino addizionato con adiuvante
(non divulgabile) nei confronti dell’infezione e dello
sviluppo della malattia indotte da Leishmania infantum
in cani naturalmente esposti in zona endemica.
In questo lavoro verrà valutata in modo
particolare l’efficacia del vaccino nei confronti
dell’attecchimento dell’infezione, mentre l’efficacia del
vaccino nei confronti dello sviluppo della
malattia, sarà oggetto della tesi di dottorato svolta dalla
dottoressa Roberta De Santo. Data la natura strettamente
correlata delle due sperimentazioni, sarà inevitabile la
presenza di alcuni punti di sovrapposizione, soprattutto
nella descrizione delle metodiche, tra i due lavori di tesi.
Prima di descrivere le metodologie d’indagine seguite nello studio si ritiene utile fornire una breve descrizione del prodotto immunizzante già testato e descritto in letteratura.
TURISMO, ALIMENTAZIONE E RISCHIO: LA PREOCCUPAZIONE DEL TURISTA CONTEMPORANEO

Publisher: name: Università degli Studi di Napoli Federico II
Year: 2011

description: Il lavoro affronta un tema recentemente frutto di interesse nelle Scienze Sociali ma che, nel tempo, sembra dover acquisire una notevole importanza.  Non vi è dubbio che il settore che, idealmente trova maggiore interesse alla tematica, è soprattutto quello turistico nel quale le dinamiche connesse all’alimentazione sembrano influenzare gli stessi comportamenti di consumo.
Nel dettaglio lo studio –oltre a presentare una parte teorica sulla relazione tra rischio, alimentazione e turismo- si addentra, successivamente, in aspetti empirici che hanno lo scopo di indagare la preoccupazione del turista contemporaneo rispetto al rischio alimentare. Quest’ultimo, di fatto, si  manifesta più intensamente laddove gli individui si trovano a contatto con cibi e bevande apparentemente diversi, nonché quando il territorio che li ospita presenta caratteristiche culturali distanti dalle proprie.
L’indagine empirica si è svolta presso il Terminal 1 dell’aeroporto internazionale di Napoli, somministrando un questionario -opportunamente formulato in linea con obiettivi ed ipotesi- ad un campione casuale di circa 342 soggetti.

description: In questa ricerca è stato analizzato il percorso filosofico, professionale e creativo dell’arch. Manfredi Nicoletti, dagli inizi della sua carriera professionale fino alle opere contemporanee. E’ stato analizzato ogni singolo progetto nella sua complessità, per capirne l’idea, lo spirito, la funzione, la scelta delle tecnologie costruttive, dei materiali ma soprattutto per interpretarne la filosofia compositiva. Questo processo di analisi è servito a stabilire quale rapporto esista oggi, o sia esistito in passato, nel processo lavorativo di questo autore, tra il movimento organicista americano e l’Italia dal secondo dopoguerra ad oggi. Nicoletti è un architetto che operato in entrambi continenti, nel periodo di nascita della filosofia organica, rappresenta un anello di giunzione tra i due movimenti, quello americano e quello Italiano. La ricerca è stata svolta con scrupolosa cura, visitando alcune delle opere sia in Italia (Roma, Arezzo, Agrigento, Catania) sia all'estero (Atene, Nuovo Museo Archeologico) raccogliendo immagini, descrizioni, particolari costruttivi tecnologici, saggi e pubblicazioni dell'autore. Il dottorando ha ben sintetizzato i caratteri dominanti dell'architettura di Nicoletti e con spirito critico ne ha analizzato la filosofia compositiva, evidenziando il rapporto ed il legame tra l'autore e il movimento organicista.

description: INTRODUZIONE:Allo stato attuale il carcinoma mammario rappresenta la più diffusa neoplasia epiteliale del sesso femminile.
L' introduzione di programmi di screening ha aumentato l' incidenza di lesioni di piccole dimensioni e ridotto la mortalità legata al tumore.
Lo stato linfonodale rappresenta un' importante fattore prognostico della malattia.Il linfonodo sentinella, quale primo linfonodo drenante l' area della lesione e pertanto interessato per primo da eventuali metastasi ha rivoluzionato il trattamento chirurgico conservato, riducendo le complicanze legate alla dissezione ascellare, che viene eseguita solo in caso di metastasi del sentinella.
E' tuttavia contraddittorio e fonte di dibattito il management di depositi micrometastatici al linfonodo sentinella.Scopo del nostro studio è valutare il significato prognostico delle micrometastasi e la nostra esperienza in relazione ai recenti trials clinici.
MATERIALI E METODI:Dal Gennaio 2003 al giugno 2011 sono state effettuate presso il nostro Dipartimento di Chirurgia 724 biopsie del linfonodo sentinella per tumori della mammella T1-T2 fino a 3 cm con linfoscintigrafia o colorante vitale.
RISULTATI:203 pazienti presentavano metastasi; di questi 51 avevano micrometastasi.Dopo linfoadenectomia ascellare di salvataggio, delle 51 pazienti con micrometastasi solo 2 avevano metastasi agli altri linfonodi ascellari.Dieci pazienti non sono state sottoposte in base alla valutazione di fattori legati al tumore a dissezione ascellare.Dopo Un follow-up di 5anni, periodo entro il quale possono verificarsi eventuali recidive ascellari, nessuna paziente ha sviluppato eventi.
CONCLUSIONI:Dai recenti studi clinici(ACOSOG Z0011) e dalla nostra esperienza, la presenza di depositi metastatici al linfonodo sentinella non necessita di terapia chirurgica ulteriore alla rimozione del sentinella in quanto la successiva dissezione ascellare non altera nè la prognosi, nè il trattamento medico, nè la sopravvivenza.

description: Nanoscale phase-control is one of the most powerful approaches to specifically tailor electrical fields in modern nanophotonics. Especially the precise sub-wavelength assembly of many individual nano-building-blocks has given rise to exciting new materials as diverse as metamaterials, for miniaturizing optics, or 3D assembled plasmonic structures for biosensing applications. Despite its fundamental importance, the phase-response of individual nanostructures is experimentally extremely challenging to visualize. Here, we address this shortcoming and measure the quantitative scattering phase of different nanomaterials such as gold nanorods and spheres as well as dielectric nanoparticles. Beyond reporting spectrally resolved responses, with phase-changes close to pi when passing the particles' plasmon resonance, we devise a simple method for distinguishing different plasmonic and dielectric particles purely based on their phase behavior. Finally, we integrate this novel approach in a single-shot two-color scheme, capable of directly identifying different types of nanoparticles on one sample, from a single widefield image.

Year: 2023

description: Background/Objective— Anecdotal data suggests that a proportion of persons after contact with coronavirus disease 2019 (COVID-19) infected individuals develop symptoms of COVID-19 but do not have the disease, an entity we term as COVID-19 mimic.Purpose—To systematically review observational studies for determining the prevalence of COVID-19 mimic among persons under surveillance.Data Sources—PubMed and National Institutes of Health website up to April 2020; and reference lists.Study Selection— Observational studies that provided the symptomatic status of persons under surveillance after exposure to COVID-19 infection and results of whether COVID-19 was excluded.Data Extraction—Two independent investigators extracted data. Confidence in the estimates of the obtained effects (quality of evidence) was assessed by using the Grading of Recommendations Assessment, Development, and Evaluation approach.Data Synthesis—13 studies fulfilled the inclusion criteria. The pooled prevalence of COVID-19 mimic was 16 per 100 persons under surveillance (95% confidence interval 11-23 per 100 persons). In the analysis of a priori subgroups, by region of the studies, prevalence of COVID-19 mimic was 16 (95% CI 11-23) in North America, 15 (95% CI 4-40) in Europe, and 15 (95% CI 7-32) per 100 persons in Asia. According to risk of bias, the prevalence of COVID-19 mimic was 21 (95% CI 13-31) in studies at high risk, 11 (95% CI 9-14) for intermediate risk, and 13 (95% CI 5-29) per 100 persons for low risk of bias. According to number of persons under surveillance, the prevalence was 12 (95% CI 8-18) and 18 (95% CI 11-29) per 100 persons in studies with less than 100 persons and studies with 100 or greater persons under surveillance.Limitations—COVID-19 was assessed with variations in selection, reporting, and ascertainment.Conclusion—A relatively high prevalence of COVID-19 mimic was noted among persons under surveillance after COVID-19 exposure

description: In this paper we have analytically investigated holographic superconductors in four dimensional Einstein-Gauss-Bonnet gravity background. Recently the novel four dimensional Einstein-Gauss-Bonnet gravity has been formulated by rescaling the Gauss-Bonnet coupling constant $α\rightarrow \fracα{d-4}$ and taking the limit $d\rightarrow 4$, and this predicts several interesting new features. To know the effect of the curvature correction on the $(2+1)$-dimensional superconductors, we have consider the $3+1$-dimensional Einstein-Gauss-Bonnet gravity. Using the Sturm-Liouville eigenvalue approach, the critical temperature and the condensation operator values has been investigated in this framework away from the probe limit. We recover the numerical results from our analytical investigation.

description: Il presente lavoro ha oggetto il confronto tra differenti metodi diagnostici in corso della Leishmaniosi del cane.
L'obiettivo, raggiunto, era dimostrare che la messa a punto, tramite la real time PCR , di una curva standard ottenuta dal clonaggio di frammenti di Leishmania in un plasmide  può rappresentare una metodica più appropriata nella valutazione dei risultati di PCR ottenuti, piuttosto che da una coltura di Leishmania.

description: Magnetic barriers in two-dimensional electron gases are shifted in B space by homogeneous, perpendicular magnetic fields. The magnetoresistance across the barrier shows a characteristic asymmetric dip in the regime where the polarity of the homogeneous magnetic field is opposite to that one of the magnetic barrier. The measurements are in quantitative agreement with semiclassical simulations, which reveal that the magnetoresistance originates from the interplay of snake orbits with E x B drift at the edges of the Hall bar and with elastic scattering.

description: We present cosmological perturbation theory in neutrino probe interacting dark-energy models, and calculate cosmic microwave background anisotropies and matter power spectrum. In these models, the evolution of the mass of neutrinos is determined by the quintessence scalar field, which is responsible for the cosmic acceleration today. We consider several types of scalar field potentials and put constraints on the coupling parameter between neutrinos and dark energy. Assuming the flatness of the universe, the constraint we can derive from the current observation is $\sum m_ν < 0.87 eV$ at the 95 % confidence level for the sum over three species of neutrinos.

description: We present a quantitative estimate of the anisotropic power and scaling of magnetic field fluctuations in inertial range magnetohydrodynamic turbulence, using a novel wavelet technique applied to spacecraft measurements in the solar wind. We show for the first time that, when the local magnetic field direction is parallel to the flow, the spacecraft-frame spectrum has a spectral index near 2. This can be interpreted as the signature of a population of fluctuations in field-parallel wavenumbers with a $k_{\parallel}^{-2}$ spectrum but is also consistent with the presence of a "critical balance" style turbulent cascade. We also find, in common with previous studies, that most of the power is contained in wavevectors at large angles to the local magnetic field and that this component of the turbulence has a spectral index of 5/3.

description: Mass spectra of the ground-state baryons consisting of three or two heavy (b or c) and one light (u,d,s) quarks are calculated in the framework of the relativistic quark model and the hyperspherical expansion. The predictions of masses of the triply and doubly heavy baryons are obtained by employing the perturbation theory for the spin-independent and spin-dependent parts of the three-quark Hamiltonian.

description: In extensions of the Standard Model with no dimensionful parameters the electroweak phase transition can be delayed to temperatures of order 100 MeV. Then the chiral phase transition of QCD can proceed with 6 massless quarks. The top-quark condensate destabilizes the Higgs potential through the Yukawa interaction, triggering the electroweak transition. Based on the symmetries of massless QCD, it has been argued that the chiral phase transition is first order. We point out that the top-Higgs Yukawa interaction is nonperturbatively large at the QCD scale, and that its effect on the chiral phase transition may not be negligible, violating some of the symmetries of massless QCD. The remaining symmetries indicate that top quarks condense in a second-order phase transition, but top condensation might also be triggered by a first-order symmetry-breaking transition in the light-quark sector.
