description: A numerical study of laminar flow through symmetric and slightly asymmetric sudden expansion, of expansion ratio 1:3, in channels with increasing cross section, is carried out using two different approaches - Conventional CFD and Lattice Boltzmann Method. The effect of divergence of walls of the channel, after a sudden expansion, on the symmetry of flow and recirculation is studied for various Reynolds numbers. It is seen that the angles of the walls play an active role in disrupting the symmetry of flow. For non-parallel walls, the symmetry breaking bifurcation phenomenon no longer exists and the loss of symmetry is a gradual process. The effect of asymmetry of geometry on flow is also studied by considering two types of asymmetry - First type is at the plane of expansion where the steps on either side are of unequal heights, while the second one deals the walls of the channel are at a different inclination with the direction of inflow. The present study reveals that small asymmetry impedes the sharp transition and thus smoothens the pitchfork bifurcation. Increased asymmetry finally leads to the unique solution of the governing Equations, indicating complete loss of bifurcation pattern.
demonologia in Plutarco di Cheronea e l'ermeneutica delle analogie mitiche fra Osiris e Dionysos nel De Iside et Osiride

description: Il presente contributo si propone di illustrare le strategie ermeneutiche messe in atto da Plutarco nel suo De Iside e Osiride, al fine di comprendere le analogie mitiche e simboliche sussistenti fra le vicende di morte e rinascita di Osiride e Dioniso. Il trattato di Plutarco (I-II sec. d. C.), insieme alle Storie di Erodoto (V sec. a. C.) e alla Biblioteca di Diodoro Siculo (I sec. a. C.), attesta l’esistenza di un dialogo interculturale fra la religione greca e quella egizia, manifesto soprattutto nella natura degli dèi. Se, tuttavia, per Erodoto e Diodoro ciò si spiegò alla luce di un primitivo diffusionismo, per Plutarco, invece, l’incontro fra Dioniso e Osiride rappresentò un enigma metafisico e teologico. Si ritiene – dunque – necessario individuare le somiglianze fenomenologiche fra Dioniso e Osiride, rinunciando a cercare l’origine storica della religione greca in Egitto. Per tale ragione, al fine di giungere alla chiarificazione del pensiero di Plutarco, innanzitutto si è tentato di comprendere i mezzi di cui si è servito Plutarco per interpretare i caratteri invarianti fra le due divinità. Nella fattispecie, il saggio si propone di illuminare la complessa demonologia plutarchea, all’interno della quale Dioniso e Osiride sono inseriti. In ultimo, sulla scorta degli studi di Bruce Lincoln, si è cercato di analizzare una delle più significative somiglianze fra i due miti, ossia lo sparagmos, l’ineffabile smembramento della divinità.

description: Two powerful and complementary experimental approaches are commonly used to study the cell cycle and cell biology: One class of experiments characterizes the statistics (or demographics) of an unsynchronized exponentially-growing population, while the other captures cell cycle dynamics, either by time-lapse imaging of full cell cycles or in bulk experiments on synchronized populations. In this paper, we study the subtle relationship between observations in these two distinct experimental approaches. We begin with an existing model: a single-cell deterministic description of cell cycle dynamics where cell states (i.e. periods or phases) have precise lifetimes. We then generalize this description to a stochastic model in which the states have stochastic lifetimes, as described by arbitrary probability distribution functions. Our analyses of the demographics of an exponential culture reveal a simple and exact correspondence between the deterministic and stochastic models: The corresponding state lifetimes in the deterministic model are equal to the exponential mean of the lifetimes in the stochastic model. An important implication is therefore that the demographics of an exponential culture will be well-fit by a deterministic model even if the state timing is stochastic. Although we explore the implications of the models in the context of the Escherichia coli cell cycle, we expect both the models as well as the significance of the exponential-mean lifetimes to find many applications in the quantitative analysis of cell cycle dynamics in other biological systems.
Frustration-induced quantum phase transitions in a quasi-one-dimensional ferrimagnet: Hard-core boson map and the Ton ks-Girardeau limit

description: We provide evidence of a superfluid-insulator transition (SIT) of magnons in a quasi-one-dimensional quantum ferrimagnet with {\it isotropic} competing antiferromagnetic spin interactions. This SIT occurs between two distinct ferrimagnetic phases due to the frustration-induced closing of the gap to a magnon excitation. It thus causes a coherent superposition of singlet and triplet states at lattice unit cells and a power-law decay on the staggered spin correlation function along the transverse direction to the spontaneous magnetization. A hard-core boson map suggests that asymptotically close to the SIT the magnons attain the Tonks-Girardeau limit. The quantized nature of the condensed singlets is observed before a first-order transition to a singlet magnetic spiral phase accompanied by critical antiferromagnetic ordering. In the limit of strong frustration, the system undergoes a decoupling transition to an isolated gapped two-leg ladder and a critical single linear chain.

description: Based on density functional theory (DFT), we have developed algorithms and a program code to investigate the electron transport characteristics for a variety of nanometer scaled devices in the presence of an external bias voltage. We employed basis sets comprised of linear combinations of numerical type atomic orbitals and k-point sampling for the realistic modeling of the bulk electrode. The scheme coupled with the matrix version of the non-equilibrium Green function method enables determination of the transmission coefficients at a given energy and voltage in a self-consistent manner, as well as the corresponding current-voltage (I-V) characteristics. This scheme has advantages because it is applicable to large systems, easily transportable to different types of quantum chemistry packages, and extendable to describe time-dependent phenomena or inelastic scatterings. It has been applied to diverse types of practical electronic devices such as carbon nanotubes, graphene nano-ribbons, metallic nanowires, and molecular electronic devices. The quantum conductance phenomena for systems involving quantum point contacts and I-V curves are described for the dithiol-benzene molecule in contact with two Au electrodes using the k-point sampling method.

description: We examine the structure of the post-shock region in supernova remnants (SNRs). The ``shock transition zone'' is set up by charge transfer and ionization events between atoms and ions, and has a width $\sim 10^{15}$ cm$^{-2}$ $n^{-1}_0$, where $n_0$ is the total pre-shock density (including both atoms and ions). For Balmer-dominated SNRs with shock velocity $v_s \gtrsim 1000$ km s$^{-1}$, the Rankine-Hugoniot conditions for ion velocity and temperature are obeyed instantly, leaving the full width at half-maximum (FWHM) of the broad H$α$ line versus $v_s$ relation intact. However, the spatial variation in the post-shock densities is relevant to the problem of Ly$α$ resonant scattering in young, core-collapse SNRs. Both two- (pre-shock atoms and ions) and three-component (pre-shock atoms, broad neutrals and ions) models are considered. We compute the spatial emissivities of the broad ($ξ_b$) and narrow ($ξ_n$) H$α$ lines; a calculation of these emissivities in SN 1006 is in general agreement with the computed ones of Raymond et al. (2007). The (dimensionless) spatial shift, $Θ_{\rm{shift}}$, between the centroids of $ξ_b$ and $ξ_n$ is unique for a given shock velocity and $f_{\rm{ion}}$, the pre-shock ion fraction. Measurements of $Θ_{\rm{shift}}$ can be used to constrain $n_0$.

The design of semantic database model SDBM
Creators: name: Xie, Linchi
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is mainly concerned with semantic data modelling related to database design. The domain of this research is restricted to general data modelling and the discussion is carried out at the conceptual level. The thesis assesses a number of serious modelling shortcomings of the conventional data models and reviews several basic principles and mechanisms developed in current semantic data modelling research. Based on these findings, the thesis identifies the inadequacy of the conceptualization of data modelling and develops the two-view conceptualization of data modelling. The basic idea behind the two-view conceptualization is that the conceptual structure of the applications being modelled should be separated from its external data representation. A new semantic database model, SDBM, is designed based on the conceptualization. The model makes a clear separation between the conceptual structure and its external data representation. It offers a data type mechanism to deal with the data representation, a window mechanism to model the conceptual structure, and a transaction mechanism to provide database operations. One of the major extensions of the current semantic data models is that with SDBM the specialization relationship is just a special case of constraints that can be specified among SDBM windows. A formal syntax and informal semantics of SDBM are given in the thesis along with comparisons between SDBM and a closely-related semantic data model, Taxis.

description: In this article we describe, a numerical simulation has been performed for a channel flow with sudden expansion. Different geometric expansion ratios are considered in the current study such as 1:2, 1:3, and 1:4. The bifurcation phenomenon has been investigated for the baseline case and the critical Reynolds number is controlled using a passive modification in the channel. The geometry of sudden expansion channel is modified by introducing a two-dimensional plate along the center line of the channel at the expansion plane. This is one of the passive control techniques, which has been explored in the present study. The computations indicate that the critical Reynolds number of the symmetry-breaking bifurcation increases as the length of the plate increases. An empirical relation has been developed amongst the critical Reynolds number, length of control plates and expansion ratio (h/H). The critical Reynolds number predicted by the empirical relation for different plate lengths are in good agreement with computational results.
Dialogo interreligioso, epistemologia analitica del disaccordo e alcuni modelli medievali

Year: 2021

description: Quando ci si riferisce al dialogo spesso si presuppone un contesto pubblico di discussione in cui sia necessario e urgente arrivare a un compromesso che assicuri un accordo tra i diversi interlocutori e che garantisca la pace sociale. Anche il dialogo interreligioso è prevalentemente concepito in quest’ottica, anche perché è nato storicamente nell’epoca moderna come tentativo di arginare la violenza derivante dalle guerre di religione. La prospettiva, invece, cambia se si considerano gli aspetti epistemologici del dialogo. Suggerisco di analizzarli a partire dalla cosiddetta epistemologia del disaccordo, sorta in ambito analitico. In questo contesto le diverse credenze religiose possono essere considerate legittime e il dialogo tra pari epistemici diventa fruttuoso al di là della convergenza delle opinioni. Dopo aver analizzato la posizione sul disaccordo religioso difesa da Helen De Cruz, mostrerò come essa può essere corroborata da ciò che è stato realizzato in alcuni scritti medievali. Prenderò in considerazione l’Utilità del credere di Agostino, L’inizio della retta guida di Al-Ghazali, il Perché un Dio uomo? di Anselmo, La guida dei perplessi di Maimonide e il Sulle ragioni della fede ad un cantore antiocheno di Tommaso. Questa analisi consente di individuare un paradigma medievale per il dialogo interreligioso interessante nel dibattito contemporaneo, in quanto capace di superare, da un lato, gli esiti violenti impliciti in un razionalismo che pretende di assolutizzare una verità religiosa rispetto alle altre e, dall’altro, gli esiti scettici di una posizione legata alla nozione di incommensurabilità. Rendere ragione della propria fede religiosa senza pretendere che il proprio interlocutore vi aderisca e impegnarsi in una conoscenza vicendevole che lasci in una condizione di disaccordo possono essere annoverati tra gli scopi del dialogo interreligioso.

description: The even-denominator states have attracted considerable attention owing to their possible applications in future quantum technologies. In this letter, we first report a 3/2 diagonal resistance, indicating the existence of a 3/2 state in a nanometer-sized triple-gated quantum point contact (QPC) fabricated on a high-mobility (not ultra-high-mobility) single-layer two-dimensional (2D) GaAs wafer. The center gate plays a crucial role in realizing the QPC's 3/2 state. Our observation of the 3/2 state using a conventional QPC device, which is a suitable building block for semiconductor quantum devices, paves a new path for the development of semiconductor-based quantum technologies.

description: We present near and mid-infrared observations of the pulsar-wind nebula (PWN) B0540-69.3 and its associated supernova remnant made with the {\it Spitzer Space Telescope}. We report detections of the PWN with all four IRAC bands, the 24 $μ$m band of MIPS, and the Infrared Spectrograph (IRS). We find no evidence of IR emission from the X-ray/radio shell surrounding the PWN resulting from the forward shock of the supernova blast wave. The flux of the PWN itself is dominated by synchrotron emission at shorter (IRAC) wavelengths, with a warm dust component longward of 20 $μ$m. We show that this dust continuum can be explained by a small amount ($\sim 1-3 \times 10^{-3} \msun$) of dust at a temperature of $\sim 50-65$ K, heated by the shock wave generated by the PWN being driven into the inner edge of the ejecta. This is evidently dust synthesized in the supernova. We also report the detection of several lines in the spectrum of the PWN, and present kinematic information about the PWN as determined from these lines. Kinematics are consistent with previous optical studies of this object. Line strengths are also broadly consistent with what one expects from optical line strengths. We find that lines arise from slow ($\sim 20$ km s$^{-1}$) shocks driven into oxygen-rich clumps in the shell swept-up by an iron-nickel bubble, which have a density contrast of $\sim 100-200$ relative to the bulk of the ejecta, and that faster shocks ($\sim 250$ km s$^{-1}$) in the hydrogen envelope are required to heat dust grains to observed temperatures. We infer from estimates of heavy-element ejecta abundances that the progenitor star was likely in the range of 20-25 $M_\odot$.

description: Come ha esemplarmente documentato Amartya Sen nel suo studio sulla tradizione razionalista e scettica nella cultura indiana, c’è, nell’India antica e poi moderna, una via peculiare al pluralismo, alla tolleranza, al riconoscimento dell’altro, alla democrazia, capace di mostrare che concetti quali razionalità, libertà, dissenso, dialettica, discussione, anche in direzione interreligiosa, non costituiscono una prerogativa occidentale. Al punto che è lecito tracciare un’ideale coordinata che rinviene la sua remota ascendenza, oltre che nei concili del primo buddhismo, nella loro apertura interreligiosa, in Aśoka, nei suoi celebri editti scolpiti sulla roccia, risalenti al III secolo a. C., ispirati al rispetto di tutte le fedi, e che, passando per Akbar, nell’India dei Moghul, giunge fino alle figure di Tagore, Gandhi, e dello stesso Sen. Intento del saggio è di delucidare, pur sinteticamente, questa coordinata, assumendo come poli di riferimento queste tre figure esemplari, che naturalmente sono ben lungi dall’esaurire l’orizzonte di questa tematica.

description: The helioglow is a fluorescence of interstellar atoms inside the heliosphere, where they are excited by the solar EUV emission. So far, the helioglow of interstellar H and He have been detected. The helioglow features a characteristic distribution in the sky, which can be used to derive both the properties of interstellar neutral gas and those of the solar wind. This requires a simulation model capable of catching with a sufficient realism the essential coupling relations between the solar factors and interstellar. The solar factors include the solar wind flux and its variation with time and heliolatitude, as well as the heliolatitude and time variation of the solar EUV output. The ISN gas inside the heliosphere features a complex distribution function, which varies with time and location. The paper presents the first version of a WawHelioGlow simulation model for the helioglow flux using an optically thin, single scattering approximation. The helioglow computations are based on a sophisticated kinetic treatment of the distribution functions of interstellar H and He provided by the (n)WTPM model. The model takes into account heliolatitudinal and spectral variations of the solar EUV output from observations. We present a formulation of the model and the treatment of the solar spectral flux. The accompanying Paper II illustrates details of the line of sight evolution of the elements of the model and a brief comparison of results of the WawHelioGlow code with selected sky maps of the hydrogen helioglow, obtained by the SWAN instrument onboard the SOHO mission.

description: Il saggio si propone di fornire alcune linee guida per lo studio del pensiero di Hilary Putnam nel campo del dialogo interreligioso. In particolare, intendo approfondire gli scritti relativi alla filosofia della religione, emersi per lo più durante gli ultimi anni della sua vita. Gli interessi per la filosofia della religione prendono le mosse dal tentativo di restituire sensatezza al linguaggio religioso in seguito al positivismo logico e si sviluppano sulla scia delle critiche alla dicotomia fatti-valori e alle riflessioni sul realismo. Dopo aver fornito una cornice biografica per meglio comprendere l’origine degli interessi religiosi, mostrerò come i suoi studi in questo campo siano fortemente influenzati dalla lettura di Wittgenstein e dalla scuola pragmatista. Chiarirò, quindi, il quadro interpretativo entro il quale ritengo che si muova la ricerca di Putnam. Infine, presenterò la sua visione pluralista, evidenziando come il ricorso a nozioni wittgensteiniane renda peculiare la sua proposta.

Separation drag reduction through a spanwise oscillating pressure gradient

description: An oscillating spanwise pressure gradient is imposed numerically to control the flow separation and reduce the drag of a turbulent flow in a channel with square bars. The transverse flow produces a maximum drag reduction of 25\%, due to lower pressure and skin-friction drag forces. The pressure drag reduction reaches a maximum of 22\% and is due to a decrease of the positive high pressure in front of the bars and an increase of the low negative pressure behind the bars. The skin-friction drag reduction is caused by a lower wall-shear stress along the cavity between the bars where the flow is fully attached, while the wall-shear stress on the crest of the bars and in the separated region behind the bars is unaffected. The spanwise laminar flow obtained by neglecting the nonlinear terms involving the turbulent velocity fluctuations is used to compute the power spent for oscillating the fluid along the spanwise direction and an excellent agreement is found with the power spent obtained by the averaged turbulent flow. A marginal or negative net power saved is found by subtracting the power employed for controlling the flow from the power saved thanks to the transverse flow. The control reduces the total drag as the integral of the Reynolds stresses along the horizontal line connecting the corners of two consecutive bars is decreased, which in turn impacts on the pressure and wall-shear stress reductions.
Karl Barth e le religioni: dialettica o dialogo?
Creators: name: Bianco, Pierangelo
Publisher: name: Nuovo Giornale di Filosofia della Religione

description: Il presente articolo intende considerare su quali basi è possibile ampliare la portata del pensiero teologico di Karl Barth al di là dei confini della chiesa evangelica in cui nacque e persino dello stesso cristianesimo. A questo scopo, saranno analizzati, all’ interno della seconda edizione de L’Epistola ai Romani , risalente al 1922, e nel successivo sv iluppo della Dogmatica Ecclesiale , i temi dell’universalità della grazia di Cristo, da una parte, e della necessità dell’apertura della Chiesa all’alterità, a partire dalla crisi della religione, dall’altra. Andrà così delineandosi, in particolare a partir e dai capitoli dal VII all’XI de L’Epistola ai Romani , il concetto chiave dell’unità di Dio Die Einheit Gottes ), ovvero, della compresenza, in Dio, di giudizio e misericordia. Inoltre, nel § 17 della Dogmatica Ecclesiale (I.2), emergerà la dialettica tra rivelazione e religione, all’interno della quale Barth intende riportare l’attenzione sull’assoluta libertà della giustizia di Dio. In questo percorso, risulterà infine centrale l’interpretazione barthiana del versetto 11,32 della Lettera di Paolo ai Roma ni: «Dio infatti ha rinchiuso tutti nella disobbedienza, per usare a tutti misericordia». In un commento a questo passo nel corso di una predicazione ai detenuti al carcere di Basilea, nel settembre 1957, il teologo affermava: « Wir dürfen und sollen mit je dem Anderen in Gedanken, Worten und Taten leben als mit Einem, dessen Gott sich auch erbarmt hat» (Noi possiamo e dobbiamo vivere con ogni altro, nella mente, nelle parole e nelle azioni, come con uno di cui il suo Dio ha avuto misericordia). Considerate q ueste premesse e tenendo conto delle autorevoli riflessioni del teologo ecumenista Adolf Keller e più recentemente degli studiosi Sven Ensminger e P.S. Chung, resta dunque da chiedersi se sia possibile offrire nuova luce sul valore che la concezione dialet tica elaborata da Barth del rapporto umano divino può avere all’interno del processo di costruzione del dialogo tra le religioni.

description: We make a short review about the synchronization in coupled phase oscillator models. Next, we study the common-noise-induced synchronization among active rotators. At an intermediate noise strength, the noise-induced synchronization takes place most effectively, which is analogous to the stochastic resonance. Finally, we study the synchronization of coupled phase oscillators with nonvariational interaction on scale-free networks. We find a sharp transition and a weak hysteresis in the nonvariational systems. The sharp transition is found also in the mean-field approximation.

We also compute the Nekrasov partition functions of the theories by applying the topological vertex formalism to the newly obtained web diagrams.

description: BERT is the most recent Transformer-based model that achieves state-of-the-art performance in various NLP tasks. In this paper, we investigate the hardware acceleration of BERT on FPGA for edge computing. To tackle the issue of huge computational complexity and memory footprint, we propose to fully quantize the BERT (FQ-BERT), including weights, activations, softmax, layer normalization, and all the intermediate results. Experiments demonstrate that the FQ-BERT can achieve 7.94x compression for weights with negligible performance loss. We then propose an accelerator tailored for the FQ-BERT and evaluate on Xilinx ZCU102 and ZCU111 FPGA. It can achieve a performance-per-watt of 3.18 fps/W, which is 28.91x and 12.72x over Intel(R) Core(TM) i7-8700 CPU and NVIDIA K80 GPU, respectively.

description: I disaccordi persistenti possono provocare nelle parti in disaccordo l’esperienza di un forte stato di ansia. Tale ansietà ha una natura psicologica nei casi di disaccordo ordinario, cioè, in casi di disaccordi che non hanno un impatto sull’identità doxastica degli agenti epistemici in contrapposizione. Al contrario, più il contenuto di un disaccordo riguarda problemi fondamentali correlati a credenze non negoziabili per le parti coinvolte, più l’ansietà di rivela essere di un genere epistemico, e, di conseguenza, promuove un insieme di conseguenze normative. Tratteggerò le principali differenze fra disaccordi ordinari e disaccordi connessi all’identità doxastica nei termini della natura dell’ansia che essi provocano. Alla luce di questa distinzione, caratterizzerò i disaccordi religiosi come disaccordi del secondo tipo, e fornirà alcuni suggerimenti per affrontarli.

description: The helioglow is a fluorescence of interstellar atoms inside the heliosphere, where they are excited by the solar EUV. Because the mean free path between collisions for the interstellar gas is comparable to the size of the heliosphere, the distribution function of this gas inside the heliosphere strongly varies in space and with time and is non-Maxwellian. Coupling between realistically modeled solar factors and the distribution function of interstellar neutral gas is accounted for in a helioglow model that we have developed. WawHelioGlow is presented in the accompanying Paper I. Here, we present the evolution of the gas density, solar illumination, helioglow source function, and other relevant parameters building up the helioglow signal for selected lines of sight observed at 1 au. We compare these elements for various phases of the solar cycle and we present the sensitivity of the results to heliolatitudinal anisotropy of the solar EUV output. We assume a realistic latitudinal anisotropy of the solar wind flux using results from analysis of interplanetary scintillations. We compare the simulated helioglow with with selected maps observed by the SOHO/SWAN instrument. We demonstrate that WawHelioGlow is able to reproduce fundamental features of the sky distribution of the helioglow. For some phases of the solar cycle, the model with an anisotropy of the solar EUV output better reproduces the observations, while for other phases no EUV anisotropy is needed. In all simulated cases, the solar wind anisotropy following insight from interplanetary scintillation measurements is present.

description: Isocyanic acid (HNCO) is a simple molecule with a potential to form prebiotic and complex organic species. Using a spectral survey collected with the Atacama Pathfinder EXperiment (APEX), in this work we report the detection of 42 transitions of HNCO in the hot molecular core/outflow G331.512-0.103 (hereafter G331). The spectral lines were observed in the frequency interval $\sim$ 160 - 355 GHz. By means of Local Thermodynamic Equilibrium (LTE) analyses, applying the rotational diagram method, we studied the excitation conditions of HNCO. The excitation temperature and column density are estimated to be $T_{ex}$ = 58.8 $\pm$ 2.7 K and $N$ = (3.7 $\pm$ 0.5) $\times$ 10$^{15}$ cm$^{-2}$, considering beam dilution effects. The derived relative abundance is between (3.8 $\pm$ 0.5) $\times $10$^{-9}$ and (1.4 $\pm$ 0.2) $\times $10$^{-8}$. In comparison with other hot molecular cores, our column densities and abundances are in agreement. An update of the internal partition functions of the four CHNO isomers: HNCO; cyanic acid, HOCN; fulminic acid, HCNO; and isofulminic acid, HONC is provided. We also used the astrochemical code Nautilus to model and discuss HNCO abundances. The simulations could reproduce the abundances with a simple zero-dimensional model at a temperature of 60 K and for a chemical age of $\sim$ 10$^5$ years, which is larger than the estimated dynamical age for G331. This result could suggest the need for a more robust model and even the revision of chemical reactions associated with HNCO.

description: Un convegno – quale quello celebratosi sotto l’egida dell’AIFR presso l’Università di Genova dal 13 al 15 novembre 2019 e intitolato «Concordia discors. Il dialogo interreligioso nello spazio della filosofia» – che ambisca a istituire un rapporto tra dialogo interreligioso e filosofia, non può che preliminarmente rispondere al senso di tale relazione. A cosa allude questa figura della filosofia? Perché quest’ultima deve occuparsi di dialogo tra le fedi? Quale apporto può venire da essa alla convivenza tra le religioni, oggi quanto mai urgente? . . .

description: In this contribution on the celebration of the 80th birthday anniversary of Prof. Ricardo Ferreira, we present a brief survey on the magnetism of quasi-one-dimensional compounds. This has been a research area of intense activity particularly since the first experimental announcements of magnetism in organic and organometallic polymers in the mid 80s. We review experimental and theoretical achievements on the field, featuring chain systems of correlated electrons in a special AB2 unit cell structure present in inorganic and organic compounds.
The $e^+ e^-\to 2(π^+π^-)π^0$, 2(π^+π^-)η$, $K^+ K^-π^+π^-π^0$ and $K^+ K^-π^+π^-η$ Cross Sections Measured with Initial-State Radiation

description: We study the processes $e^+ e^-\to 2(π^+π^-)π^0γ$, $2(π^+π^-)ηγ$, $K^+ K^-π^+π^-π^0γ$ and $K^+ K^-π^+π^-ηγ$ with the hard photon radiated from the initial state. About 20000, 4300, 5500 and 375 fully reconstructed events, respectively, are selected from 232 fb$^{-1}$ of BaBar data. The invariant mass of the hadronic final state defines the effective $e^+ e^-$ center-of-mass energy, so that the obtained cross sections from the threshold to about 5 GeV can be compared with corresponding direct \epem measurements, currently available only for the $ηπ^+π^-$ and $ωπ^+π^-$ submodes of the $e^+ e^-\to 2(π^+π^-)π^0$ channel. Studying the structure of these events, we find contributions from a number of intermediate states, and we extract their cross sections where possible. In particular, we isolate the contribution from $e^+ e^-\toω(782)π^+π^-$ and study the $ω(1420)$ and $ω(1650)$ resonances. In the charmonium region, we observe the $J/ψ$ in all these final states and several intermediate states, as well as the $ψ(2S)$ in some modes, and we measure the corresponding branching fractions.

description: He state of the microvasculature of the liver has been studied, and a quantitative assessment of the changes occurring during hypoxic and hemic experimental hypoxia is given. A comprehensive analysis of the state of rheological properties of blood in close relationship with the properties of dynamic viscosity and shear rate of blood in hypoxic and hemic experimental hypoxia is presented. According to the results of the study, it can be assumed that in the initial stages of hypoxemia, the liver largely compensates for the lack of oxygen in the flowing blood by increasing its extraction. With hypoxia, taking into account the characteristics of the hepatic blood flow, one can assume an important role of circulatory disorders in the pathological processes developing in the liver with severe forms of hypoxia. The regular increase in blood viscosity revealed in severe forms of hypoxia at velocity gradients simulating the conditions of blood flow in microvessels was a direct confirmation of the emerging microcirculatory disorders. Taking them into account is important for understanding the pathogenesis of developing pathological changes in the liver.

description: Decay constants of $P$-wave mesons are computed in the framework of instantaneous Bethe-Salpeter method (Salpeter method). By analyzing the parity and possible charge conjugation parity, we give the relativistic configurations of wave functions with definite parity and possible charge conjugation parity. With these wave functions as input, the full Salpeter equations for different $P$-wave states are solved, and the mass spectra as well as the numerical values of wave functions are obtained. Finally we compute the leptonic decay constants of heavy-heavy and heavy-light $^3P_0$, $^3P_1$ and $^1P_1$ states.

description: In this article, some issues of priority directions for the development of the juvenile justice system in the Republic of Kazakhstan were discussed. The basics of implementing the juvenile justice system in the Republic of Kazakhstan and the importance of juvenile justice have been identified, which will improve the efficiency and quality of execution at all stages.Also, after a comparative analysis of the system of juvenile justice in foreign countries, Kazakhstan provides for the improvement of the system of juvenile justice. The Ministry of justice and the bar have identified issues of creating specialized units for working with minors. In particular, it is proposed to create a special educational service as one of the bases for improving the juvenile justice system.
Large-scale, Multi-temporal Remote Sensing of Palaeo-river Networks: A Case Study from Northwest India and its Implications for the Indus Civilisation
Creators: name: Petrie, Cameron

Publisher: name: MDPI AG
Year: 2017

description: Remote sensing has considerable potential to contribute to the identification and reconstruction of lost hydrological systems and networks. Remote sensing-based reconstructions of palaeo-river networks have commonly employed single or limited time-span imagery, which limits their capacity to identify features in complex and varied landscape contexts. This paper presents a seasonal multi-temporal approach to the detection of palaeo-rivers over large areas based on long-term vegetation dynamics and spectral decomposition techniques. The use of multi-temporal data has allowed the overcoming of seasonal cultivation patterns and long-term visibility issues related to crop selection, large-scale irrigation and land use patterns. The application of this approach on the Sutlej-Yamuna interfluve (northwest India), a core area for the Bronze Age Indus Civilisation, has enabled the reconstruction of an unsuspectedly complex palaeo-river network comprising more than 8000 kms of palaeo-channels. It has also enabled the definition of the morphology of these relict courses, which provides insights into the environmental conditions in which they operated. These new data will contribute to a better understanding of the settlement distribution and environmental settings in which this, often considered riverine, civilisation operated.

description: The main result states that every convex set-valued function defined on a real interval with compact values in a locally convex space, admits an affine selection. In the case if the target space is a real line and the values are closed real intervals, we can replace the convexity assumption by the more general condition.

description: We compute the second moments of pion and rho parton distribution functions (PDFs) in lattice QCD with $N_f = 2+1$ flavors of improved Wilson fermions. We determine both singlet and non-singlet flavor combinations and, for the first time, take disconnected contributions fully into account. In the case of the rho, we also calculate the additional contribution arising from the $b_1$ structure function. The numerical analysis includes 26 ensembles, mainly generated by the CLS effort, with pion masses ranging from 420MeV down to 214MeV and with 5 different lattice spacings in the range of 0.1fm to 0.05fm. This enables us to take the continuum limit, as well as to resolve the quark mass dependencies reliably. Additionally we discuss the contaminations of rho correlation functions by two-pion states.
