description: This paper presents a novel approach to handle the challenges of face recognition. In this work thermal face images are considered, which minimizes the affect of illumination changes and occlusion due to moustache, beards, adornments etc. The proposed approach registers the training and testing thermal face images in polar coordinate, which is capable to handle complicacies introduced by scaling and rotation. Polar images are projected into eigenspace and finally classified using a multi-layer perceptron. In the experiments we have used Object Tracking and Classification Beyond Visible Spectrum (OTCBVS) database benchmark thermal face images. Experimental results show that the proposed approach significantly improves the verification and identification performance and the success rate is 97.05%.

description: The development of society in the modern era faces new challenges. Consequently, the vector coordinates of community development are constantly changing and its determination area lies in the information sphere. When we say information sphere, we mean adaptation, orientation and its importance in hard problems. It is obvious that solving the problem will make the process more available. Development of any field of business is one chain of systemic actions, which can be presented by the variety of incoming and outgoing information streams for various purposes. It allows us to monitor the market constantly, its dynamics, behaviour, condition. All this is necessary for a businessman for being competitive. The use of modern technologies allows convenient and effective analysis of business management, which is a major contributing factor for arranging information sphere.

description: Georgia is particularly rich in natural and cultural resources, their optimal use will make the country as the world-class tourist product and create the opportunity to get the unique impressions. This kind of strategic approach is more likely to attract high-paying tourists not only from the post-Soviet countries, but also from the European Union, the US, the Middle East and Asia. In order to realize it is necessary to provide the convenient and affordable by simplified air travel from important tourist markets. This, in turn, requires further development of the civil aviation sector, which will help to increase the number of international and local flights. Therefore, the business environment cannot be improved without the development of economic cooperation forms between the state and private companies, which ultimately ensures the effective operation of not only the aviation, but also the country's overall transport system. Thus, our state and its government should review the existing regulations and develop the approaches that will make the national companies more secure, active and effective.

description: This work investigates the $H\gamma$ final state in $\sqrt{s}=240 GeV$ collisions at the FCC-ee, housing an electron-positron collider. The utilized event reconstruction is based on IDEA, a detector concept study for FCC-ee

The final state in question relies on loop-based production and provides insight in the effective $H\gamma\gamma$ and $H\gamma Z$ coupling. Based on the recoil mass method, the analysis comprises both, an inclusive as well as an exclusive study of the $\mathrm{H}\rightarrow b\bar{b}$ channel.The final measurement precision is evaluated by a cut & count analysis in comparison with a likelihood fit on the photon recoil mass. The inclusive measurement results in an expected precision of 228% (cut & count) and 234% (likelihood fit).The exclusive study yields a precision of 156% and 149%, respectively.  Compatible results are found for each evaluated selection.

Residue Communities Reveal Evolutionary Signatures of Protein Function
Creators: name: Cheung, N.J.
Publisher: name: Zenodo
Year: 2020
Subjects: Residue communities, evolutionary coupling

description: Naturally co-occurring amino acids, term coevolution, in a protein family play a significant role in both protein engineering and folding, and it is expanding in recent years from the studies of the effects of single-site mutations to the complete re-design of a protein and its folding, especially in structure prediction. Here we report an approach that can identify the evolutionary signatures (highly ordered networks of coupled amino acids, termed "residue communities", RCs) from protein homologous sequences. The method provides access to apply the spectrum analysis on evolutionary coupling analysis (SAEC) for inferring RCs in proteins and their important roles in protein function.

description: At the dawn of the first discovery of exoplanets orbiting sun-like stars in the mid-1990s, few believed that observations of exoplanet atmospheres would ever be possible. After the 2002 Hubble Space Telescope detection of a transiting exoplanet atmosphere, many skeptics discounted it as a one-object, one-method success. Nevertheless, the field is now firmly established, with over two dozen exoplanet atmospheres observed today. Hot Jupiters are the type of exoplanet currently most amenable to study. Highlights include: detection of molecular spectral features; observation of day-night temperature gradients; and constraints on vertical atmospheric structure. Atmospheres of giant planets far from their host stars are also being studied with direct imaging. The ultimate exoplanet goal is to answer the enigmatic and ancient question, "Are we alone?" via detection of atmospheric biosignatures. Two exciting prospects are the immediate focus on transiting super Earths orbiting in the habitable zone of M-dwarfs, and ultimately the spaceborne direct imaging of true Earth analogs.

Overcoming challenges on HCV glycoproteins and receptors production
Creators: name: Wang, Yuanyuan
Publisher: name: No Publisher Supplied
Year: 2019

description: Hepatitis C is a liver disease caused by hepatitis C virus (HCV). HCV is the major cause of cirrhosis and hepatocellular cancer in the US and is the number one cause of liver transplantation. An estimate of 3.5 million people is chronically infected in the US with 400,000 individuals deaths from chronic HCV infection every year.  Several direct-acting antiviral (DAA) agents have been approved by the Food and Drug Administration (FDA). HCV is a blood-borne virus, which prior to 1992 was transmitted through blood transfusion. An estimated 41,200 new cases of HCV infection occurred in the US with an additional 1.75 million worldwide in 2016. Therefore, there is an urgent need to control the transmission of HCV, in addition to the antiviral intervention to limit the spread of the virus. Vaccination is the most effective way to control the infection rate as no infectious disease has ever been eradicated by treatment alone. However, no vaccine is available to prevent HCV infection.A useful mammalian cell expression system was described to produce HCV envelope glycoproteins E1 and E2, as well as the cell surface receptors, scavenger receptor class B type I (SRB1) and cluster of differentiation 81 (CD81). Our method combines the speed and high efficiency of lentiviral infection with an adherent cell bioreactor to allow large-scale production of proteins in mammalian cell lines. The full-length ectodomain of HCV E1 was produced at milligram quantity and is recognized by conformational antibodies from patient samples. E1 can associate with the apolipoproteins from the cell culture serum. HCV E2 produced by the mammalian cell expression system has the function to bind cell surface receptors and antibodies. Crystals of E2 and CD81 diffract to 4.3 Å resolution allowing us to produce a low-resolution model of the E2-receptor complex.Overall, our result extends the current understanding of HCV entry by providing more structural, biophysical, and functional information on the HCV glycoproteins. The studies of the receptor interaction can contribute to vaccine design to halt the spread of HCV infection.

description: We explore the additional security obtained by noise at the physical layer in a wiretap channel model setting. Security enhancements at the physical layer have been proposed recently using a secrecy metric based on the degrees of freedom that an attacker has with respect to the sent ciphertext. Prior work focused on cases in which the wiretap channel could be modeled as statistically independent packet erasure channels for the legitimate receiver and an eavesdropper. In this paper, we go beyond the state-of-the-art by addressing correlated erasure events across the two communication channels. The resulting security enhancement is presented as a function of the correlation coefficient and the erasure probabilities for both channels. It is shown that security improvements are achievable by means of judicious physical-layer design even when the eavesdropper has a better channel than the legitimate receiver. The only case in which this assertion may not hold is when erasures are highly correlated across channels. However, we are able to prove that correlation cannot nullify the expected security enhancement if the channel quality of the legitimate receiver is strictly better than that of the eavesdropper.

The effects of familial hypercholesterolemia on Achilles tendon biomechanics : a cross-sectional study
Creators: name: Squier, Kip
Publisher: name: University of British Columbia
Year: 2018

description: Familial hypercholesterolemia (FH), a common genetic metabolic disorder characterized by high cholesterol levels, is involved in the development of atherosclerosis and other preventable diseases. FH can also cause tendinous abnormalities, such as thickening and xanthoma (tendon lipid accumulation) in the Achilles and extensor tendons, which may impact and impede tendon biomechanics. There is evidence that high cholesterol may lead to tendon injury or pain, but tendon biomechanics has received little investigation in people with FH. The objective of this study was to investigate how FH can affect Achilles tendon biomechanics, in vivo. 16 FH participants were recruited locally from the British Columbia FH Registry database. 16 control participants were recruited from purposeful convenience sampling. All participants completed preferred pace walking trials, shod, on a fully instrumented treadmill to collect gait impact data. Achilles tendon (AT) biomechanical data was obtained according to previously published methodology; simultaneously, lower limb kinematics, and muscle-tendon junction displacement were measured by motion capture and b-mode ultrasound imaging, respectively. AT strain, stiffness and hysteresis were calculated using a custom built Matlab program. AT biomechanical outcomes were assessed for statistical differences using MANCOVA. 16 FH participants (10 males, 6 females, 37±6 years, BMI of 28±4 kg/m²) and 16 control participants (10 males, 6 females, 36±7 years, BMI of 27±3 kg/m2) were recruited. FH participants displayed similar AT peak strain (FH: 5.07±0.9%, Controls: 4.95±0.9%; p=0.790), lower stiffness (FH: 87±20 N/mm, Controls: 111±18 N/mm; p=0.001), and higher hysteresis (FH: 56±17%, Controls: of 35±12%; p=0.007), when compared to controls. To the best of our knowledge, this is the first study that evaluates the impact of FH on AT biomechanics, in vivo. The results of the current study provide evidence that cholesterol accumulation can negatively affect AT biomechanics and potentially increase the chance of injury. The findings of this study will be of interest to clinicians, and people with FH and high cholesterol.

description: For a type-II superconductor, when the applied magnetic field is higher than the lower critical value Hc1, the magnetic flux will penetrate into the superconductor and form quantized vortices, which usually are arranged in an Abrikosov lattice. For the newly discovered iron pnictide superconductors, previous measurements have shown that, in electron-doped BaFe2As2, the vortices form a highly disordered structure. In addition, the density of states (DOS) within the vortex cores1 do not exhibit the Andreev bound states in conventional superconductors. In this Letter, we report the observation of a triangular vortex lattice and the Andreev bound states in hole-doped BaFe2As2 by using a low temperature scanning tunneling microscope (STM). Detailed study of the vortex cores reveals that the spectrum of the Andreev bound states inside the vortex core exhibits a distinct spatial evolution: at the center of the vortex core, it appears as a single peak at 0.5 mV below the Fermi-energy; away from the core center, it gradually evolves into two sub-peaks and they eventually fade out. The drastic differences between the vortex cores of the electron-doped and hole-doped counterparts are illusive to the pairing mechanism of the iron pnictide superconductors.

description: Subject of this paper is the simplification of Markov chain Monte Carlo sampling as used in Bayesian statistical inference by means of normalising flows, a machine learning method which is able to construct an invertible and differentiable transformation between Gaussian and non-Gaussian random distributions. We use normalising flows to compute Bayesian partition functions for non-Gaussian distributions and show how normalising flows can be employed in finding analytical expressions for posterior distributions beyond the Gaussian limit. Flows offer advantages for the numerical evaluation of the partition function itself, as well as for cumulants and for the information entropy. We demonstrate how normalising flows in conjunction with Bayes partitions can be used in inference problems in cosmology and apply them to the posterior distribution for the matter density $Ω_m$ and a dark energy equation of state parameter $w_0$ on the basis of supernova data.
Applied electric field instead of pressure in H-based superconductors

Subjects: subject: Superconductivity (cond-mat.supr-con)

description: In our desire to give a new suggestion for H-based superconductors experiments we present a theoretical framework for understanding the impact of an applied electric field on pressured hydride superconductors. We study a material at pressure $p$, when it possesses insulator-superconductor transition, at the respective superconducting critical temperature $T_{cr}$. The theory shows the applied electric field penetrates the material and forces the Cooper pairs to Bose condensate. If one applies an electric field and then increases the temperature, the theory predicts novel critical temperature $T^{el}_{cr}$ higher than $T_{cr}$. Therefore, the system has a higher superconducting critical temperature if we apply an electric field instead of increasing the pressure. The result shows that in the case of carbonaceous sulfur hydride at $234Gpa$ and near but below critical temperature $T_c=283K$, applying a sufficiently strong electric field, we can bring the superconducting critical temperature close to 300K.

description: We consider repulsive potential energies $\E_q(Σ)$, whose integrand measures tangent-point interactions, on a large class of non-smooth $m$-dimensional sets $Σ$ in $\R^n.$ Finiteness of the energy $\E_q(Σ)$ has three sorts of effects for the set $Σ$: topological effects excluding all kinds of (a priori admissible) self-intersections, geometric and measure-theoretic effects, providing large projections of $Σ$ onto suitable $m$-planes and therefore large $m$-dimensional Hausdorff measure of $Σ$ within small balls up to a uniformly controlled scale, and finally, regularizing effects culminating in a geometric variant of the Morrey-Sobolev embedding theorem: Any admissible set $Σ$ with finite $\E_q$-energy, for any exponent $q>2m$, is, in fact, a $C^1$-manifold whose tangent planes vary in a Hölder continuous manner with the optimal Hölder exponent $μ=1-(2m)/q$. Moreover, the patch size of the local $C^{1,μ}$-graph representations is uniformly controlled from below only in terms of the energy value $\E_q(Σ)$.

description: The matching problem plays a basic role in combinatorial optimization and in statistical mechanics. In its stochastic variants, optimization decisions have to be taken given only some probabilistic information about the instance. While the deterministic case can be solved in polynomial time, stochastic variants are worst-case intractable. We propose an efficient method to solve stochastic matching problems which combines some features of the survey propagation equations and of the cavity method. We test it on random bipartite graphs, for which we analyze the phase diagram and compare the results with exact bounds. Our approach is shown numerically to be effective on the full range of parameters, and to outperform state-of-the-art methods. Finally we discuss how the method can be generalized to other problems of optimization under uncertainty.

description: We present a method for discovering dense packings of general convex hard particles and apply it to study the dense packing behavior of a one-parameter family of particles with tetrahedral symmetry representing a deformation of the ideal mathematical tetrahedron into a less ideal, physical, tetrahedron and all the way to the sphere. Thus, we also connect the two well studied problems of sphere packing and tetrahedron packing on a single axis. Our numerical results uncover a rich optimal-packing behavior, compared to that of other continuous families of particles previously studied. We present four structures as candidates for the optimal packing at different values of the parameter, providing an atlas of crystal structures which might be observed in systems of nano-particles with tetrahedral symmetry.

description: We report the discovery of the first eclipsing detached double white dwarf (WD) binary. In a pulsation search, the low-mass helium core WD NLTT 11748 was targeted for fast (approx 1 minute) differential photometry with the Las Cumbres Observatory's Faulkes Telescope North. Rather than pulsations, we discovered approx 180 s 3%-6% dips in the photometry. Subsequent radial velocity measurements of the primary white dwarf from the Keck telescope found variations with a semi-amplitude K_1 = 271 +/- 3 km/s, and confirmed the dips as eclipses caused by an orbiting WD with a mass M_2 = 0.648-0.771 M_sun for M_1 = 0.1-0.2 M_sun. We detect both the primary and secondary eclipses during the P_orb = 5.64 hr orbit and measure the secondary's brightness to be 3.5% +/- 0.3% of the primary at SDSS-g'. Assuming that the secondary follows the mass-radius relation of a cold C/O WD and including the effects of microlensing in the binary, the primary eclipse yields a primary radius of R_1 = 0.043-0.039 R_sun for M_1 = 0.1-0.2 M_sun, consistent with the theoretically expected values for a helium core WD with a thick, stably burning hydrogen envelope. Though nearby (at approx 150 pc), the gravitational wave strain from NLTT 11748 is likely not adequate for direct detection by the Laser Interferometer Space Antenna. Future observational efforts will determine M_1, yielding accurate WD mass-radius measurement of both components, as well as a clearer indication of the binary's fate once contact is reached.

description: Absorption spectra of small molecular aggregates (oligomers) are considered. The dipole-dipole interaction between the monomers leads to shifts of the oligomer spectra with respect to the monomer absorption. The line-shapes of monomer as well as oligomer absorption depend strongly on the coupling to vibrational modes. Using a recently developed approach [Roden et. al, PRL 103, 058301] we investigate the length dependence of spectra of one-dimensional aggregates for various values of the interaction strength between the monomers. It is demonstrated, that the present approach is well suited to describe the occurrence of the J- and H-bands.

description: We discuss the concept of an all-optical and ionizing matter-wave interferometer in the time domain. The proposed setup aims at testing the wave nature of highly massive clusters and molecules, and it will enable new precision experiments with a broad class of atoms, using the same laser system. The propagating particles are illuminated by three pulses of a standing ultraviolet laser beam, which detaches an electron via efficient single photon-absorption. Optical gratings may have periods as small as 80 nm, leading to wide diffraction angles for cold atoms and to compact setups even for very massive clusters. Accounting for the coherent and the incoherent parts of the particle-light interaction, we show that the combined effect of phase and amplitude modulation of the matter waves gives rise to a Talbot-Lau-like interference effect with a characteristic dependence on the pulse delay time.

Optimal design of water distribution networks under uncertainty
Creators: name: Moosavian, Seyed Abdolnaser
Publisher: name: University of British Columbia

description: Generally, the use of the water distribution network (WDN) modeling is divided into two main categories, WDN design, and WDN hydraulic analysis, which itself is employed as part of WDN design. The former generally identifies components of the network, considering the system cost and the ability of the network to satisfy consumer demands for water availability, pressure, and quality. The latter evaluates the distribution of nodal pressures and pipe flows under a specified network design and known or estimated water consumption levels. WDN analysis is often embedded within design algorithms, where, for every potential design considered, the hydraulic energy and continuity equations that govern the system are solved. If water demands and the physical characteristics of the network design are known with certainty, deterministic approaches for solving these equations may be used. If some information is uncertain, non-deterministic approaches are used for identifying the Probability Density Function or the fuzzy membership functions of the pressure and flow conditions at all locations in the network. This dissertation is divided into three main parts, 1) the application and development of evolutionary algorithms for single- and multi-objective optimization of WDNs, 2) the introduction of new frameworks and performance surrogates as objectives in the optimization of WDNs, and 3) the advancement of an efficient gradient-based technique for fuzzy analysis of WDNs under uncertainty. First, efficient Evolutionary Algorithms (EAs) are compared and advanced for reducing the computational burden of single- and multi-objective design of WDNs, respectively. We investigate and identify the most appropriate operators and characteristics of EAs for optimization of realistic-sized networks. Based on the experiences and capabilities of EAs obtained, a new EA is introduced for single-objective optimization of WDNs which is faster and more reliable than other popular algorithms presented in the literature. Next, two different frameworks are introduced for implementing many objectives in the optimization of realistic-sized WDNs. Both approaches can distinguish appropriate design solutions with minimum cost and maximum hydraulic and mechanical reliability. Finally, a fuzzy method is introduced for analysis of WDNs under uncertainty. The proposed technique significantly reduces the CPU time of uncertainty analysis of large-scale networks.

description: We study the binding energies of singlet trions, i.e. charged excitons, in carbon nanotubes. The problem is modeled, through the effective-mass model, as a three-particle complex on the surface of a cylinder, which we investigate using both one- and two-dimensional expansions of the wave function. The effects of dimensionality and correlation are studied in detail. We find that the Hartree-Fock approximation significantly underestimates the trion binding energy. Combined with band structures calculated using a non-orthogonal nearest neighbour tight binding model, the results from the cylinder model are used to compute physical binding energies for a wide selection of carbon nanotubes. In addition, the dependence on dielectric screening is examined. Our findings indicate that trions are detectable at room temperature in carbon nanotubes with radius below 8Å.

description: Significant progress has been made recently in our understanding of the structure of stellar magnetic fields, thanks to advances in detection methods such as Zeeman-Doppler Imaging. The extrapolation of this surface magnetic field into the corona has provided 3D models of the coronal magnetic field and plasma. This method is sensitive mainly to the magnetic field in the bright regions of the stellar surface. The dark (spotted) regions are censored because the Zeeman signature there is suppressed. By modelling the magnetic field that might have been contained in these spots, we have studied the effect that this loss of information might have on our understanding of the coronal structure. As examples, we have chosen two stars (V374 peg and AB Dor) that have very different magnetograms and patterns of spot coverage. We find that the effect of the spot field depends not only on the relative amount of flux in the spots, but also its distribution across the stellar surface. For a star such as AB Dor with a high spot coverage and a large polar spot, at its greatest effect the spot field may almost double the fraction of the flux that is open (hence decreasing the spindown time) while at the same time increasing the X-ray emission measure by two orders of magnitude and significantly affecting the X-ray rotational modulation.

description: The background of this research is an event when some of the students of Sriwijaya University reportedly became supporters of an extremist organization named Islamic State of Iraq and Syria (ISIS) in 2015. Purposes of the research that’s using library research are to trace back a root of the event and formulize a thought as a framework of thinking which can be used as prevention against extremism. Through an adoption of Antonio Gramci’s epistemological conception about Organic Intellectual as research limitation, the idea of “Neo-Sutarto” which consisted by three components : Neo-Sufism, Tarbiya, and Tolerance is founded by the researcher. Neo-Sufism is well-known as reform kind of Tasawuf and useful for balancing exoterics and esoterics aspects, while educatively Tarbiya is used to convert a great values of Neo-Sufism within an awareness of intellectuality, and Tolerance is implemented as the result of Sulh-i-Kul or “Universal Peace.” This research proves that Neo-Starto is eligible to be recommended and implemented in the Sriwijaya University through its steps such as : providing some literatures which contained stramlining of misconseption about Islam, encouraging university mentoring and supervision system towards the emergence of ideologies, holding the tolerance themed socialization and discussion, and creating a physical sphere of Neo-Sutarto through monumental buildings or entertainment to promote pluralism and peace.

description: Since the launch of the Einstein X-ray Observatory in the 1970s, a number of broad absorption features have been reported in the X-ray spectra of BL Lac objects. These features are often interpreted as arising from high velocity outflows intrinsic to the BL Lac object, therefore providing important information about the inner environment around the central engine. However, such absorption features have not been observed more recently with high-resolution X-ray telescopes such as Chandra and XMM-Newton. In this paper, we report the detection of a transient X-ray absorption feature intrinsic to the BL Lac object H 2356-309 with the Chandra X-ray Telescope. This BL Lac object was observed during XMM cycle 7, Chandra cycle 8 and 10, as part of our campaign to investigate X-ray absorption produced by the warm-hot intergalactic medium (WHIM) residing in the foreground large scale superstructure. During one of the 80 ksec, Chandra cycle 10 observations, a transient absorption feature was detected at 3.3-sigma (or 99.9% confidence level, accounting for the number of trials), which we identify as the OVIII K-alpha line produced by an absorber intrinsic to the BL Lac object. None of the other 11 observations showed this line. We constrain the ionization parameter (25

description: Observations from the X-ray telescope (XRT) on Hinode are used to study the nature of X-ray bright points, sources of coronal jets. Several jet events in the coronal holes are found to erupt from small-scale, S-shaped bright regions. This finding suggests that coronal micro-sigmoids may well be progenitors of coronal jets. Moreover, the presence of these structures may explain numerous observed characteristics of jets such as helical structures, apparent transverse motions, and shapes. In analogy to large-scale sigmoids giving rise to coronal mass ejections (CMEs), a promising future task would perhaps be to investigate whether solar eruptive activity, from coronal jets to CMEs, is self-similar in terms of properties and instability mechanisms.
