description: Recently, the outbreak of the novel Coronavirus disease 2019 (COVID-19) pandemic has seriously endangered human health and life. Due to limited availability of test kits, the need for auxiliary diagnostic approach has increased. Recent research has shown radiography of COVID-19 patient, such as CT and X-ray, contains salient information about the COVID-19 virus and could be used as an alternative diagnosis method. Chest X-ray (CXR) due to its faster imaging time, wide availability, low cost and portability gains much attention and becomes very promising. Computational methods with high accuracy and robustness are required for rapid triaging of patients and aiding radiologist in the interpretation of the collected data. In this study, we design a novel multi-feature convolutional neural network (CNN) architecture for multi-class improved classification of COVID-19 from CXR images. CXR images are enhanced using a local phase-based image enhancement method. The enhanced images, together with the original CXR data, are used as an input to our proposed CNN architecture. Using ablation studies, we show the effectiveness of the enhanced images in improving the diagnostic accuracy. We provide quantitative evaluation on two datasets and qualitative results for visual inspection. Quantitative evaluation is performed on data consisting of 8,851 normal (healthy), 6,045 pneumonia, and 3,323 Covid-19 CXR scans. In Dataset-1, our model achieves 95.57\% average accuracy for a three classes classification, 99\% precision, recall, and F1-scores for COVID-19 cases. For Dataset-2, we have obtained 94.44\% average accuracy, and 95\% precision, recall, and F1-scores for detection of COVID-19. Our proposed multi-feature guided CNN achieves improved results compared to single-feature CNN proving the importance of the local phase-based CXR image enhancement (https://github.com/endiqq/Fus-CNNs_COVID-19).

description: The majority of the dairy products imported by the United States are intermediate products used in food processing. As such, they are demanded for their components such as milk fat and protein. The implications of the U.S. tariff structure for import demand must be viewed in terms of the tariff's effects upon the relative prices of imported milk components. In this article we examine the implications of the current tariff structure and proposed changes under the Doha Round of international trade negotiations at the World Trade Organization. We show that implicit ad valorem equivalent tariffs (AVEs) on components vary substantially under the current tariff schedule. Proposed changes under the Doha Round would lead to not only a reduction in the level of implied tariffs on components, but also a reduction in dispersion. This would help to reduce the possibility of distortions due to significant differences in component prices across intermediate dairy products.

description: We show how many contemporary issues in event generation can be recast in terms of partonic calculations with a matching scale. This framework is called GenEvA, and a key ingredient is a new notion of phase space which avoids the problem of phase space double-counting by construction and includes a built-in definition of a matching scale. This matching scale can be used to smoothly merge any partonic calculation with a parton shower. The best partonic calculation for a given region of phase space can be determined through physics considerations alone, independent of the algorithmic details of the merging. As an explicit example, we construct a positive-weight partonic calculation for e+e- -> n jets at next-to-leading order (NLO) with leading-logarithmic (LL) resummation. We improve on the NLO/LL result by adding additional higher-multiplicity tree-level (LO) calculations to obtain a merged NLO/LO/LL result. These results are implemented using a new phase space generator introduced in a companion paper [arXiv:0801.4028].

Biophysical and anticancer properties of mitoxantrone in programmable fusogenic vesicles
Creators: name: Adlakha-Hutcheon, Gitanjali
Publisher: name: University of British Columbia
Year: 2009

description: This thesis characterizes programmable fusogenic vesicles (PFVs) and examines their usefulness as carriers for an anticancer drug. PFVs are cationic liposomes designed to exhibit time-dependent destabilization. They consist of non-bilayer-forming lipids that are stabilized into a bilayer by exchangeable poly(ethylene glycol)-conjugated lipids (PEGlipids). The rate at which the vesicles destabilize is determined by the rate at which the bilayer stabilizing component, PEG-phosphatidylethanolamine (PEG-PE), exchanges out of the vesicle. In turn, this exchange rate is controlled by the acyl composition of the PEG-PE. PFVs are composed of l,2-dioleoyl-5«-glycero-3-phosphoethanolamine (DOPE), cholesterol (CHOL), ArN-dioleyl-N, Af-dimethylammonium chloride (DODAC) and a PEGconjugated lipid. The morphology of PFVs was examined as a function of lipid composition using cryo-transmission electron microscopy (cryo-TEM). While predominantly unilamellar, PFVs exhibit a variety of morphologies, including spherical, discoid and invaginated shapes. In the absence of PEG-lipid, PFVs formed in distilled water are spherical unilamellar structures but aggregation/fusion is observed when these systems are placed in isotonic saline. An essential finding is that despite the high proportion of non-bilayer-forming lipids in PFVs, these vesicles can efficiently accumulate the anticancer drug mitoxantrone in response to an imposed transmembrane proton gradient. Release of intravesicular contents of PFVs was demonstrated using radiolabeled sucrose. The rates of plasma elimination and biodistribution of PFVs and mitoxantrone-loaded PFVs were characterized as functions of PEG-PE acyl chain length. The presence of mitoxantrone did not alter the time-course of elimination of PFVs from the circulation. The rate of elimination of PFVs from the circulation depended on the chain length of PEG-lipid anchor. This is because long chain lengths of PEG-PE slow its loss from the PFV surface and, in turn, prolong the blood residence of PFVs. For instance, PFVs containing PEG-1,2-distearoyl-s«-phosphoethanolamine (DSPE) showed the slowest exchange and the longest blood residence times among the three anchors examined. The efficacy and accumulation within tumors of mitoxantrone-loaded PFVs were examined using a human colon carcinoma (LSI80) xenograft in severe combined immune deficient (SCID) mice. PFVs prepared with a slow-exchanging PEG-lipid delayed tumor progression more effectively than either PFVs that are rapidly eliminated from the circulation or conventional liposomes. Efficacy of mitoxantrone-loaded PFVs was also evaluated against a murine tumor model in which disease progression occurs primarily in the liver. All PFV formulations were significantly more active against this tumor model than free mitoxantrone or mitoxantrone-loaded conventional liposomes suggesting that PFVs are capable of releasing drug more efficiently than conventional formulations.

description: A family of random variables $\mathbf{X}(s)$, depending on a real parameter $s>-\frac{1}{2}$, appears in the asymptotics of the joint moments of characteristic polynomials of random unitary matrices and their derivatives, in the ergodic decomposition of the Hua-Pickrell measures and conjecturally in the asymptotics of the joint moments of Hardy's function and its derivative. Our first main result establishes a connection between the characteristic function of $\mathbf{X}(s)$ and the $σ$-Painlevé III' equation in the full range of parameter values $s>-\frac{1}{2}$. Our second main result gives the first explicit expression for the density and all the complex moments of the absolute value of $\mathbf{X}(s)$ for integer values of $s$. Finally, we establish an analogous connection to another special case of the $σ$-Painlevé III' equation for the Laplace transform of the sum of the inverse points of the Bessel point process.

description: Using quantum systems to efficiently solve quantum chemistry problems is one of the long-sought applications of near-future quantum technologies. In a recent work, ultra-cold fermionic atoms have been proposed for these purposes by showing us how to simulate in an analog way the quantum chemistry Hamiltonian projected in a lattice basis set. Here, we continue exploring this path and go beyond these first results in several ways. First, we numerically benchmark the working conditions of the analog simulator, and find less demanding experimental setups where chemistry-like behaviour in three-dimensions can still be observed. We also provide a deeper understanding of the errors of the simulation appearing due to discretization and finite size effects and provide a way to mitigate them. Finally, we benchmark the simulator characterizing the behaviour of two-electron atoms (He) and molecules (HeH$^+$) beyond the example considered in the original work.

description: It has been recently shown that the Bekenstein entropy bound is not respected by the systems satisfying modified forms of Heisenberg uncertainty principle (HUP) including the generalized and extended uncertainty principles, or even their combinations. On the other, the use of generalized entropies, which differ from Bekenstein entropy, in describing gravity and related topics signals us to different equipartition expressions compared to the usual one. In that way, The mathematical form of an equipartition theorem can be related to the algebraic expression of a particular entropy, different from the standard Bekenstein entropy, initially chosen to describe the black hole event horizon, see E. M. C. Abreu et al., MPLA 32, 2050266 (2020). Motivated by these works, we address three new uncertainty principles leading to recently introduced generalized entropies. In addition, the corresponding energy-time uncertainty relations and Unruh temperatures are also calculated. As a result, it seems that systems described by generalized entropies, such as those of Tsallis, do not necessarily meet HUP and may satisfy modified forms of HUP.

description: In January I972, an in-depth investigation of an unstable embankment, Figure 1, on US 119 near Station 1262+00 was initiated. The site is approximately five miles southwest of Harlan and near Wilhoit. Figures 2 and 3 show a plan view and a typical cross-section, respectively. US 119 travels on a tangent from Station 1252+16 to 1255+54 in a northerly direction. From that point, the roadway gradually curves four degrees to the east, becoming tangent again near Station 1275+00. At about Station 1258+00, the roadway emerges from a cut, and near Station 1266+00 it reenters a small cut. Between the latter two stations the embankment is sidehill, resting partly on a bench of cut shale and partly on an alluvium and colluvium river bank. Maximum height of the unstable embankment is about 25 feet. The unstable portion of the embankment, Figure 2, is between Stations 1260+00 and 1265+00 (approximately). The roadway embankment is bounded on the north by a cliff varying from 50 to 100 feet in height and on the south by the Cumberland River.

description: By referring to the underlying physics behind the color charge neutrality condition in quark matter, we discuss how this condition should be properly imposed in NJL-type models in a phenomenologically meaningful way. In particular, we show that the standard assumption regarding the use of two color chemical potentials, chosen in a very special way, is not justified in general. When used uncritically, such an approach leads to wrong or unphysical conclusions.

We show that the $σ$-infinitesimal generator of a $σ$-dynamics of inner $σ$-endomorphisms is an inner $σ$-derivation and deal with the converse. We also establish a nice generalized Leibniz formula and extend the Kleinenckr--Sirokov theorem for $σ$-derivations under certain conditions.

description: In this paper, we present one- and two-loop results for the renormalization of the gluon and quark gauge-invariant operators which appear in the definition of the QCD energy-momentum tensor, in dimensional regularization. To this end, we consider a variety of Green's functions with different incoming momenta. We identify the set of twist-2 symmetric traceless and flavor singlet operators which mix among themselves and we calculate the corresponding mixing coefficients for the nondiagonal components. We also provide results for some appropriate regularization-independent (RI')-like schemes, which address this mixing, and we discuss their application to nonperturbative studies via lattice simulations. Finally, we extract the one- and two-loop expressions of the conversion factors between the proposed RI' and the MSbar schemes. From our results regarding the MSbar-renormalized Green's functions, one can easily derive conversion factors relating numerous variants of RI'-like schemes to MSbar. To make our results easily accessible, we also provide them as Supplemental Material, in the form of a Mathematica input file and, also, an equivalent text file.

description: A description is given of a remote sensing, multiple-point, mercury-filled settlement gage designed for measuring in-place settlements. The gage consists of settlement units positioned at locations where settlement measurements are desired and a monitoring unit located outside of construction limits. Settlement readings are observed on a mercury manometer located at the monitoring site and are· equal to the differences in initial and subsequent pressure head readings. Comparisons of measurements obtained at a highway construction site from mercury gage settlement units and conventional settlement platforms are presented and show very good agreement. With the mercury gage, a large amount of settlement information can. be obtained per installation, and the gage does not have many of the disadvantages associated with the settlement platform.

description: Nanocrystalline materials have unique properties such as high ultimate strength and superior hardness. However, they also exhibit some disadvantages, such as low thermal stability. An effective strategy to address this issue is alloying with other materials. Grain boundaries play a pivotal role in property prediction due to their orientation between grains and the complexity of their structure. The prediction of structure-property relationships for GBs with microstructural complexity represents a difficult challenge.To understand the effects of dopants on the material properties of grain boundaries, we constructed some bicrystal models for Al and Mg-doped Al (Al-Mg) alloys. Findings from shearing simulations of these GBs indicate that the GB structure and dopant distribution can influence GB migration. Dopants inhibit GB migration at certain GBs, effectively reinforcing these GBs. Shear-coupled GB migration in pure Al, as well as dopant inhibition of GB Al-Mg alloys, both contribute to the mechanisms of GB migration.

description: The nanohertz frequency band explored by pulsar timing arrays provides a unique discovery space for gravitational wave signals. In addition to signals from anticipated sources, such as those from supermassive black hole binaries, some previously unimagined sources may emit transient gravitational waves (a.k.a. bursts) with unknown morphology. Unmodeled transients are not currently searched for in this frequency band, and they require different techniques from those currently employed. Possible sources of such gravitational wave bursts in the nanohertz regime are parabolic encounters of supermassive black holes, cosmic string cusps and kinks, or other, as-yet-unknown phenomena. In this paper we present BayesHopperBurst, a Bayesian search algorithm capable of identifying generic gravitational wave bursts by modeling both coherent and incoherent transients as a sum of Morlet-Gabor wavelets. A trans-dimensional Reversible Jump Markov Chain Monte Carlo sampler is used to select the number of wavelets best describing the data. We test BayesHopperBurst on various simulated datasets including different combinations of signals and noise transients. Its capability to run on real data is demonstrated by analyzing data of the pulsar B1855+09 from the NANOGrav 9-year dataset. Based on a simulated dataset resembling the NANOGrav 12.5-year data release, we predict that at our most sensitive time-frequency location we will be able to probe gravitational wave bursts with a root-sum-squared amplitude higher than $\sim 5 \times 10^{-11}$ Hz$^{-1/2}$, which corresponds to $\sim 40 M_{\odot} c^2$ emitted in GWs at a fiducial distance of 100 Mpc.

description: We present deep, wide-field g and r photometry of the transition type dwarf galaxy Leo T, obtained with the blue arm of the Large Binocular Telescope. The data confirm the presence of both very young (<1 Gyr) as well as much older (>5 Gyr) stars. We study the structural properties of the old and young stellar populations by preferentially selecting either population based on their color and magnitude. The young population is significantly more concentrated than the old population, with half-light radii of 104+-8 and 148+-16 pc respectively, and their centers are slightly offset. Approximately 10% of the total stellar mass is estimated to be represented by the young stellar population. Comparison of the color-magnitude diagram (CMD) with theoretical isochrones as well as numerical CMD-fitting suggest that star formation began over 10 Gyr ago and continued in recent times until at least a few hundred Myr ago. The CMD-fitting results are indicative of two distinct star formation bursts, with a quiescent period around 3 Gyr ago, albeit at low significance. The results are consistent with no metallicity evolution and [Fe/H] ~ -1.5 over the entire age of the system. Finally, the data show little if any sign of tidal distortion of Leo T.

description: We present a detailed $^{31}$P nuclear magnetic resonance (NMR) study of the molecular rotation in the compound [Cu(pz)$_{2}$(2-HOpy)$_{2}$](PF$_{6}$)$_{2}$, where pz = C$_4$H$_4$N$_2$ and 2-HOpy = C$_5$H$_4$NHO. Here, a freezing of the PF$_6$ rotation modes is revealed by several steplike increases of the temperature-dependent second spectral moment, with accompanying broad peaks of the longitudinal and transverse nuclear spin-relaxation rates. An analysis based on the Bloembergen-Purcell-Pound (BPP) theory quantifies the related activation energies as $E_{a}/k_{B}$ = 250 and 1400 K. Further, the anisotropy of the second spectral moment of the $^{31}$P absorption line was calculated for the rigid lattice, as well as in the presence of several sets of PF$_6$ reorientation modes, and is in excellent agreement with the experimental data. Whereas the anisotropy of the frequency shift and enhancement of nuclear spin-relaxation rates is driven by the molecular rotation with respect to the dipole fields stemming from the Cu ions, the second spectral moment is determined by the intramolecular interaction of nuclear $^{19}$F and $^{31}$P moments in the presence of the distinct rotation modes.

description: We consider motion of an overdamped Brownian particle subject to stochastic resetting in one dimension. In contrast to the usual setting where the particle is instantaneously reset to a preferred location (say, the origin), here we consider a finite time resetting process facilitated by an external linear potential $V(x)=λ|x|~ (λ>0)$. When resetting occurs, the trap is switched on and the particle experiences a force $-\partial_x V(x)$ which helps the particle to return to the resetting location. The trap is switched off as soon as the particle makes a first passage to the origin. Subsequently, the particle resumes its free diffusion motion and the process keeps repeating. In this set-up, the system attains a non-equilibrium steady state. We study the relaxation to this steady state by analytically computing the position distribution of the particle at all time and then analysing this distribution using the spectral properties of the corresponding Fokker-Planck operator. As seen for the instantaneous resetting problem, we observe a `cone spreading' relaxation with travelling fronts such that there is an inner core region around the resetting point that reaches the steady state, while the region outside the core still grows ballistically with time. In addition to the unusual relaxation phenomena, we compute the large deviation functions associated to the corresponding probability density and find that the large deviation functions describe a dynamical transition similar to what is seen previously in case of instantaneous resetting. Notably, our method, based on spectral properties, complements the existing renewal formalism and reveals the intricate mathematical structure responsible for such relaxation phenomena. We verify our analytical results against extensive numerical simulations.

description: According to the fireball model gamma-ray burst (GRB) afterglows are the result of a shock pushed into the surrounding medium by an extremely relativistic outflow from the GRB. By modeling the broadband spectrum, ranging from X-ray to radio wavelengths, on time scales of hours to years after the GRB, we can determine several burst parameters, e.g. the burst energy, the circumburst medium density (and its gradient) and the energy contained in electrons and the magnetic field. We have developed a code to do broadband modeling and determine the model parameters. We also performed Monte Carlo simulations with synthetic data sets in order to derive an estimate of the accuracy of the best fit parameters. GRB970508 was taken as a case study and we present our fitting results. We also present our WSRT radio observations of GRB030329 at centimeter wavelengths and the results from modeling this afterglow. The low frequency WSRT radio observations provide a unique possibility to study the late stages of the fireball evolution and examine the jet structure.

description: This paper examines the effects of local workforce creativity on county-level earnings. Descriptive analysis of the data shows that most of the high-creativity counties in the United States are part of metropolitan areas, and that employee earnings are high in these places. Regression results indicate that, other things being equal, workforce creativity enhances county-level labor earnings. However, the returns to creativity that we found can be confirmed only in the urban context. An extension of the analysis suggests that the creative workforce wage premium may be capturing the effects of "technical workforce creativity" on earnings.

On persistence properties in weighted spaces for solutions of the fractional Korteweg-de Vries equation

description: Persistence problems in weighted spaces have been studied for different dispersive models involving non-local operators. Generally, these models do not propagate polynomial weights of arbitrary magnitude, and the maximum decay rate is associated with the dispersive part of the equation. Altogether, this analysis is complemented by unique continuation principles that determine optimal spatial decay. This work is intended to establish the above questions for a weakly dispersive perturbation of the inviscid Burgers equation. More precisely, we consider the fractional Korteweg-de Vries equation, which comprises the Burgers-Hilbert equation and dispersive effects weaker than those of the Benjamin-ono equation.

description: Thanks to recent progress in high-throughput experimental techniques, the datasets of large-scale protein interactions of prototypical multicellular species, the nematode worm Caenorhabditis elegans and the fruit fly Drosophila melanogaster, have been assayed. The datasets are obtained mainly by using the yeast hybrid method, which contains false-positive and false-negative simultaneously. Accordingly, while it is desirable to test such datasets through further wet experiments, here we invoke recent developed network theory to test such high throughput datasets in a simple way. Based on the fact that the key biological processes indispensable to maintaining life are universal across eukaryotic species, and the comparison of structural properties of the protein interaction networks (PINs) of the two species with those of the yeast PIN, we find that while the worm and the yeast PIN datasets exhibit similar structural properties, the current fly dataset, though most comprehensively screened ever, does not reflect generic structural properties correctly as it is. The modularity is suppressed and the connectivity correlation is lacking. Addition of interlogs to the current fly dataset increases the modularity and enhances the occurrence of triangular motifs as well. The connectivity correlation function of the fly, however, remains distinct under such interlogs addition, for which we present a possible scenario through an in silico modeling.

Identification of Leishmania mexicana amastigote-specific genes and proteins
Creators: name: Bellatin, Jaime Antonio
Publisher: name: University of British Columbia
Year: 2009

description: The leishmaniases are parasitic human diseases that constitute a public health problem in many parts of the world. The diseases are caused by the protozoan Leishmania that as amastigotes are intracellular parasites of the host's macrophages. The efforts to control these diseases will be greatly aided by a better understanding of the Leishmania amastigote and its complex relationship with its mammalian host. Leishmania genes that are preferentially expressed in amastigotes encode proteins that are likely involved in amastigote-specific functions. The first approach used in this thesis was the identification and isolation of amastigote surface proteins. The surface proteins of the amastigote are likely to have a significant role in the host-parasite relationship as they stand in the interphase between the two organisms. This approach was pursued by the generation of monoclonal antibodies directed against the surface of amastigotes. Major surface proteins of L. mexicana axenicculture amastigotes were found to be glycoprotein 63 and a novel protein complex, consisting of three polypeptides of 110, 86 and 70 kDa. This protein complex appeared to be amastigote-specific as it was not detected on the surface of L. mexicana promastigotes and appeared on the surface of cultured Leishmania when they differentiated from promastigotes to amastigotes. The second approach of the thesis was the identification and characterization of amastigote-specific genes by subtractive hybridization. Two amastigote-specific genes were identified and sequenced: A600 and A850. A600 was abundantly expressed in the amastigotes and found to code for a novel small polypeptide of 93 amino acids, the first 42 of which were a predicted signal peptide, implying that the A600 polypeptide may be secreted by the amastigotes. The other amastigote-specific gene identified, A850, encoded a β- tubulin isogene. The A850 mRNA had a unique 3' UTR that hybridized with two copies out of the multiple p-tubulin genes. The amino acid sequence of the A850 gene was compared to that of the three other reported Leishmania p-tubulin genes and the four genes were found to be highly conserved with variable amino acids at only a few defined positions.

description: Evaluating expectations on an Ising model (or Boltzmann machine) is essential for various applications, including statistical machine learning. However, in general, the evaluation is computationally difficult because it involves intractable multiple summations or integrations; therefore, it requires approximation. Monte Carlo integration (MCI) is a well-known approximation method; a more effective MCI-like approximation method was proposed recently, called spatial Monte Carlo integration (SMCI). However, the estimations obtained using SMCI (and MCI) exhibit a low accuracy in Ising models under a low temperature owing to degradation of the sampling quality. Annealed importance sampling (AIS) is a type of importance sampling based on Markov chain Monte Carlo methods that can suppress performance degradation in low-temperature regions with the force of importance weights. In this study, a new method is proposed to evaluate the expectations on Ising models combining AIS and SMCI. The proposed method performs efficiently in both high- and low-temperature regions, which is demonstrated theoretically and numerically.
