description: The use of iris as a biometric trait is widely used because of its high level of distinction and uniqueness. Nowadays, one of the major research challenges relies on the recognition of iris images obtained in visible spectrum under unconstrained environments. In this scenario, the acquired iris are affected by capture distance, rotation, blur, motion blur, low contrast and specular reflection, creating noises that disturb the iris recognition systems. Besides delineating the iris region, usually preprocessing techniques such as normalization and segmentation of noisy iris images are employed to minimize these problems. But these techniques inevitably run into some errors. In this context, we propose the use of deep representations, more specifically, architectures based on VGG and ResNet-50 networks, for dealing with the images using (and not) iris segmentation and normalization. We use transfer learning from the face domain and also propose a specific data augmentation technique for iris images. Our results show that the approach using non-normalized and only circle-delimited iris images reaches a new state of the art in the official protocol of the NICE.II competition, a subset of the UBIRIS database, one of the most challenging databases on unconstrained environments, reporting an average Equal Error Rate (EER) of 13.98% which represents an absolute reduction of about 5%.

description: This paper aims to substantiate the theoretical positions and develop practical recommendations for the development of tools for analytical assessment of enterprise development taking into account the educational-professional potential of the personnel (in the management system) as a factor of the effectiveness of the functioning of the enterprise and the formation of its prospect. The obtained results improve the analytical method of the complex assessment of the enterprise development, which, unlike the existing ones, takes into account the following inalienable structural components (absolute business indicators): 1) the scale of enterprise development considering the level of educational-professional potential personnel in the management system; 2) the level of quality of enterprise development. The authors established that in order to ensure the effective development of any enterprise, the following two basic (fundamental) requirements must be fulfilled, namely: 1) a quality system of enterprise management; 2) high (or optimal, desirable) level of competitiveness and investment attractiveness of the enterprise, which directly depends on the educational-professional potential of employees in management system. It is determined that the educational-professional potential of personnel should be understood as the possibilities, knowledge and skills, competence and practical skills, which employees have mastered in educational institutions or during through self-education.

description: Quantum tomography is currently the mainly employed method to assess the information of a system and therefore plays a fundamental role when trying to characterize the action of a particular channel. Nonetheless, quantum tomography requires the trust that the devices used in the laboratory perform state generation and measurements correctly. This work is based on the theoretical framework for the device-independent inference of quantum channels that was recently developed and experimentally implemented with superconducting qubits in [Dall'Arno, Buscemi, Vedral, arXiv:1805.01159] and [Dall'Arno, Brandsen, Buscemi, PRSA 473, 20160721 (2017)]. Here, we present a complete experimental test on a photonic setup of two device-independent quantum channels falsification and characterization protocols to analyze, validate, and enhance the results obtained by conventional quantum process tomography. This framework has fundamental implications in quantum information processing and may also lead to the development of new methods removing the assumptions typically taken for granted in all the previous protocols.

Random Matrix Theory and Chiral Symmetry in QCD

description: Random matrix theory is a powerful way to describe universal correlations of eigenvalues of complex systems. It also may serve as a schematic model for disorder in quantum systems. In this review, we discuss both types of applications of chiral random matrix theory to the QCD partition function. We show that constraints imposed by chiral symmetry and its spontaneous breaking determine the structure of low-energy effective partition functions for the Dirac spectrum. We thus derive exact results for the low-lying eigenvalues of the QCD Dirac operator. We argue that the statistical properties of these eigenvalues are universal and can be described by a random matrix theory with the global symmetries of the QCD partition function. The total number of such eigenvalues increases with the square root of the Euclidean four-volume. The spectral density for larger eigenvalues (but still well below a typical hadronic mass scale) also follows from the same low-energy effective partition function. The validity of the random matrix approach has been confirmed by many lattice QCD simulations in a wide parameter range. Stimulated by the success of the chiral random matrix theory in the description of universal properties of the Dirac eigenvalues, the random matrix model is extended to nonzero temperature and chemical potential. In this way we obtain qualitative results for the QCD phase diagram and the spectrum of the QCD Dirac operator. We discuss the nature of the quenched approximation and analyze quenched Dirac spectra at nonzero baryon density in terms of an effective partition function. Relations with other fields are also discussed.

Dynamic Optimization of Thermodynamically Rigorous Models of Multiphase Flow in Porous Subsurface Oil Reservoirs

Year: 2018

description: In this paper, we consider dynamic optimization of thermal and isothermal oil recovery processes which involve multicomponent three-phase flow in porous media. We present thermodynamically rigorous models of these processes based on 1) conservation of mass and energy, and 2) phase equilibrium. The conservation equations are partial differential equations. The phase equilibrium problems that are relevant to thermal and isothermal models are called the UV and the VT flash, and they are based on the second law of thermodynamics. We formulate these phase equilibrium problems as optimization problems and the phase equilibrium conditions as the corresponding first order optimality conditions. We demonstrate that the thermal and isothermal flow models are in a semi-explicit differential-algebraic form, and we solve the dynamic optimization problems with a previously developed gradient-based algorithm implemented in C/C++. We present numerical examples of optimized thermal and isothermal oil recovery strategies and discuss the computational performance of the dynamic optimization algorithm in these examples.

description: The time evolution of a collisionless plasma is modeled by the Vlasov-Maxwell system which couples the Vlasov equation (the transport equation) with the Maxwell equations of electrodynamics. We only consider a 'two-dimensional' version of the problem since existence of global, classical solutions of the full three-dimensional problem is not known. We add external currents to the system, in applications generated by coils, to control the plasma in a proper way. After considering global existence of solutions to this system, differentiability of the control-to-state operator is proved. In applications, on the one hand, we want the shape of the plasma to be close to some desired shape. On the other hand, a cost term penalizing the external currents shall be as small as possible. These two aims lead to minimizing some objective function. We restrict ourselves to only such control currents that are realizable in applications. After that, we prove existence of a minimizer and deduce first order optimality conditions and the adjoint equation.

This search is based on 12.7 pb$^{-1}$ of data. Second generation leptoquarks are assumed to be produced in pairs and to decay into a muon and quark with branching ratio $β$ or to neutrino and quark with branching ratio $(1-β)$. We obtain cross section times branching ratio limits as a function of leptoquark mass and set a lower limit on the leptoquark mass of 111 GeV/c$^{2}$ for $β= 1 $ and 89 GeV/c$^{2}$ for $β= 0.5 $ at the 95%\ confidence level.

description: We investigate the effect of dynamical fermions on the sphaleron transition rate at finite temperature for the Abelian Higgs model in one spatial dimension. The fermion degrees of freedom are included through bosonization. Using a numerical simulation, we find that massless fermions do not change the rate within the measurement accuracy. Surprisingly, the exponential dependence of the sphaleron energy on the Yukawa coupling is not borne out by the transition rate, which shows a very weak dependence on the fermion mass.

description: We report the self-assembly of thin actin shells beneath the membranes of giant vesicles. Ion-carrier mediated influx of Mg2+ induces actin polymerization in the initially spherical vesicles. Buckling of the vesicles and the formation of blisters after thermally induced bilayer expansion is demonstrated. Bilayer flickering is dominated by tension generated by its coupling to the actin cortex. Quantitative flicker analysis suggests the bilayer and the actin cortex are separated by 0.4 \mum to 0.5 \mum due to undulation forces.

description: Fundamental concepts in quantum physics and technological applications ranging from the detection of gravitational waves to the generation of stimulated Brillouin scattering rely on the interaction between the optical and the mechanical degrees of freedom.\ A key parameter to engineer this interaction is the spatial overlap between the two fields, optimized in carefully designed resonators on a case-by-case basis.\ Disorder is an alternative strategy to confine light and sound at the nanoscale.\ However, it lacks an \textit{a priori} mechanism guaranteeing a high degree of co-localization due to the inherently complex nature of the underlying interference process.\ Here, we propose a way to address this challenge by using GaAs/AlAs vertical distributed Bragg reflectors with embedded geometrical disorder.\ Due to a remarkable coincidence in the physical parameters governing light and motion propagation in these two materials, the equations for both longitudinal acoustic waves in the growth direction and normal-incidence light become practically equivalent for excitations of the same wavelength.\ This guarantees spatial overlap between photons and phonons leading to a statistically significant enhancement in the vacuum optomechanical coupling rate, $g_{0}$, and making this system a promising candidate to explore Anderson localization of high frequency ($\sim$ 20 GHz) phonons enabled by cavity optomechanics.\

Madame d’Urre sa fille est instituée héritière pour les biens d’Aubais, en sorte la bibliothèque qui est au château lui appartient. Elle y est avec monsieur son fils, le comte d’Urre, et l’on est après de faire l’état des biens et des charges. Dès que cela sera fini on pensera à mettre la bibliothèque en vente. J’irai voir cette dame après Pâques et dire le dernier adieu à ce grand recueil de livres qui m’était extrêmement utile. Je saurai alors plus particulièrement ce qu’on médite pour parvenir à cette vente, si l’on fait imprimer un catalogue, comme il parait convenable, il faudra du tems pour le faire, et alors on le répandra afin que tous les concurrens puissent faire leurs propositions. Je puis vous assurer qu’on est déjà très résolu à s’en défaire. On y avait le scellé, je ne sais pas si on l’a levé.

On m’a remis votre billet sur la médaille fourrée dont l’âme est de fer.

description: In inflationary cosmology, the particles constituting the Universe are created after inflation due to their interaction with moving inflaton field(s) in the process of preheating. In the fermionic sector, the leading channel is out-of equilibrium particle production in the non-perturbative regime of parametric excitation, which respects Pauli blocking but differs significantly from the perturbative expectation. We develop theory of fermionic preheating coupling to the inflaton, without and with expansion of the universe, for light and massive fermions, to calculate analytically the occupation number of created fermions, focusing on their spectra and time evolution. In the case of large resonant parameter $q$ we extend for rermions the method of successive parabolic scattering, earlier developed for bosonic preheating. In an expanding universe parametric excitation of fermions is stochastic. Created fermions very quickly, within tens of inflaton oscillations, fill up a sphere of radius $\simeq q^{1/4}$ in monetum space. We extend our formalism to the production of superheavy fermions and to `instant' fermion creation.

description: Among the various things made from tobacco is snuff. The microbiological contamination of locally made snuff sold in Eke-Igboji market was investigated using standard microbiological procedure. Aliquots (0.1 ml) of the serially-diluted samples were plated out on the surface of nutrient agar, mannitol salt agar and potato dextrose agar in petri dishes. The plates also had 0.05mg/ml of ketoconazole to inhibit fungal growth and the plates were incubated at 28˚C for 24 hours while for the fungi 0.05 mg/ml  of chloramphenicol  was used to inhibit bacterial growth while it was incubation was at 28˚C for 72 hours.The bacteria identified were Corynebacterium sp, Micrococcus sp, Staphylococcus sp, Bacillus sp and Pseudomonas sp whereas the fungi were Aspergillus sp, Rhizopus sp, Alternaria sp, Geotrichum sp, Penicillium sp and Aspergillus sp. The bacterial count were between 2.9 x 102 cfu/ml and 6.8 x 102 cfu/ml while the fungal count was from 1.0 x 102 cfu/ml to 4.4 x 102 cfu/ml. The most common type of bacteria found was Staphylococcus spp (52.43%) and Corynebacterium sp was the least common (7.65%) while for fungi Aspergillus spp  (27.00%) was found to be the most common while Geotrichum sp had the lowest frequency (5.40%).These microorganisms, which may have entered the snuff from the air, soil, dust, storage containers and human handlers are known to be harmful to humans. Therefore, in order to reduce the risk associated with the use of snuff by the snuff handlers, snuff must be processed and handled hygienically and the vendors should be educated on the health implications of taking a microbially contaminated snuff.

description: Purpose: Cancer risks for Nagasaki survivors once appeared to be lower than for Hiroshima survivors. The possibility that this was due to overestimation of the doses for the Nagasaki survivors was tested by measuring biological doses of Nagasaki survivors and comparing them with DS02R1 individual doses as previously done for Hiroshima survivors. Materials and methods: The electron spin resonance (ESR) method and cytogenetic method were used to estimate radiation doses for 24 Nagasaki survivors, and the results were compared to calculated DS02R1 doses. Results: Six factory workers and 10 other survivors showed ESR or cytogenetically estimated doses that were in reasonably good agreement with their DS02R1 doses, while one factory worker was found to have an ESR dose estimate of nearly one half of the DS02R1 dose to the eye lens (a proxy organ for teeth). A few outliers were also observed. Conclusions: Although apparently lower cancer risks were observed in the past for Nagasaki survivors when compared to Hiroshima survivors, the present results do not indicate the existence of a trend that DS02R1 doses are overestimated when compared with biologically estimated tooth or cytogenetic doses. This observation is in line with the recent disappearance of the city difference in cancer risks.

Diffusion of pro- and anti-false information tweets: the Black Panther movie case

description: Much has been made of the importance of the speed at which disinformation diffuses through online social media and this speed is an important aspect to consider when designing interventions. An additional complexity is that there can be different types of false information that travel from and through different communities who respond in various ways within the same social media conversation. Here we present a case study/example analysis exploring the speed and reach of three different types of false stories found in the Black Panther movie Twitter conversation and comparing the diffusion of these stories with the community responses to them. We find that the negative reaction to fake stories of racially-motivated violence whether in the form of debunking quotes or satirical posts can spread at speeds that are magnitudes higher than the original fake stories. Satire posts, while less viral than debunking quotes, appear to have longer lifetimes in the conversation. We also found that the majority of mixed community members who originally spread fake stories switched to attacking them. Our work serves as an example of the importance of analyzing the diffusion of both different types of disinformation and the different responses to it within the same overall conversation.

description: We present autoionization spectra of metastable Ar(8+) and C(4+), N(5+), O(6+) and Ne(8+) scattering off an Al(111) surface with incident energies down to 5 eV. The unprecedented quality of the experimental data permits the observation of a unique, yet undiscovered peak in the structures originating from the metastable projectiles compared to corresponding ground state configurations. Analyzing the peak positions for different projectile species and velocities we demonstrate that the peak must be ascribed to an above-surface transition under participation of the metastable state.

Chiral symmetry breaking, color superconductivity and quark matter phase diagram: a variational approach

description: We discuss in this note simultaneous existence of chiral symmetry breaking and color superconductivity at finite temperature and density in a Nambu-Jona-Lasinio type model. The methodology involves an explicit construction of a variational ground state and minimisation of the thermodynamic potential. There exists solutions to the gap equations at finite densities with both quark antiquark as well as diquark condensates for the "ground" state. However, such a phase is thermodynamically unstable with the pressure being negative in this region. We also compute the equation of state, and obtain the structure of the phase diagram in the model.

HEMORRHAGIC DISORDERS IN THE EARLY STAGES OF ARTERIAL HYPERTENSION
Creators: name: Narzulaeva, Umida
Publisher: name: Zenodo
Year: 2024

description: Aim of the study: Early diagnosis of blood rheology disorders in patients with the first stage of arterial hypertension in the arid region of Uzbekistan.

Material and methods: As an object of study, a total of 204 patients aged 35 to 55 years with a diagnosis of first-stage hypertension with no additional disease were screened. Of these, 122 formed the main group and 82 formed the patient control group. All patients underwent Komplex clinical trials and examination of hemoreological parameters.

Results: The results observed in the main group of patients showed a significant difference in the rheological parameters at the rotational speed of M (1) 5 and M (1) 10 seconds in patients with grade 2 arterial hypertension compared with those in the control group. (p <0.05).

description: We study the neutrino-photon processes such as $γγ\to ν\barν$ and $νγ\to νγ$ in a background magnetic field smaller than the critical magnetic field $B_c\equiv m_e^2/e$. Using Schwinger's proper-time method, we extract leading magnetic-field contributions to the above processes. Our result is valid throughout the kinematic regime where both neutrino and photon energies are significantly smaller than $m_W$. We briefly discuss the astrophysical implications of our result.

Measurement of the Omega_c Lifetime

Publisher: name: arXiv
Year: 1995
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: We present the measurement of the lifetime of the Omega_c we have performed using three independent data samples from two different decay modes. Using a Sigma- beam of 340 GeV/c we have obtained clean signals for the Omega_c decaying into Xi- K- pi+ pi+ and Omega- pi+ pi- pi+, avoiding topological cuts normally used in charm analysis. The short but measurable lifetime of the Omega_c is demonstrated by a clear enhancement of the signals at short but finite decay lengths. Using a continuous maximum likelihood method we determined the lifetime to be tau(Omega_c) = 55 +13-11(stat) +18-23(syst) fs. This makes the Omega_c the shortest living weakly decaying particle observed so far. The short value of the lifetime confirms the predicted pattern of the charmed baryon lifetimes and demonstrates that the strong interaction plays a vital role in the lifetimes of charmed hadrons.

Path Integral Formulation of the Conformal Wess-Zumino-Witten to Toda Reductions

description: The phase space path integral Wess-Zumino-Witten $\to$ Toda reductions are formulated in a manifestly conformally invariant way. For this purpose, the method of Batalin, Fradkin, and Vilkovisky, adapted to conformal field theories, with chiral constraints, on compact two dimensional Riemannian manifolds, is used. It is shown that the zero modes of the Lagrange multipliers produce the Toda potential and the gradients produce the WZW anomaly. This anomaly is crucial for proving the Fradkin-Vilkovisky theorem concerning gauge invariance.

Non-commutative time-frequency tomography

Subjects: subject: Data Analysis, Statistics and Probability (physics.data-an)

description: The characterization of non-stationary signals requires joint time and frequency information. However, time (t) and frequency (omega) being non-commuting variables there cannot be a joint probability density in the (t,omega) plane and the time-frequency distributions, that have been proposed, have difficult interpretation problems arising from negative or complex values and spurious components. As an alternative we propose to obtain time-frequency information by looking at the marginal distributions along rotated directions in the (t,omega) plane. The rigorous probability interpretation of the marginal distributions avoids all interpretation ambiguities. Applications to signal analysis and signal detection are discussed as well as an extension of the method to other pairs of non-commuting variables.
