description: The main goal of this paper is to set up the coarse-grained formulation of a fractional Schrödinger equation that incorporates a higher (spatial) derivative term which accounts for relativistic effects at a lowest order. The corresponding continuity equation is worked out and we also identify the contribution of the relativistic correction the quantum potential in the coarse-grained treatment. As a consequence, in the classical regime, we derive the sort of fractional Newtonian law with the quantum potential included and the fractional conterparts of the De Broglies's energy and momentum relations.

description: The finite range adiabatic wave approximation provides a practical method to analyze (d,p) or (p,d) reactions, however until now the level of accuracy obtained in the description of the reaction dynamics has not been determined. In this work, we perform a systematic comparison between the finite range adiabatic wave approximation and the exact Faddeev method. We include studies of $^{11}$Be(p,d)$^{10}$Be(g.s.) at $E_p=$5, 10 and 35 MeV; $^{12}$C(d,p)$^{13}$C(g.s.) at $E_d=$7, 12 and 56 MeV and $^{48}$Ca(d,p)$^{49}$Ca(g.s.) at $E_d=$19, 56 and 100 MeV. Results show that the two methods agree within $\approx 5%$ for a range of beam energies ($E_d \approx 20-40$ MeV) but differences increase significantly for very low energies and for the highest energies. Our tests show that ADWA agrees best with Faddeev when the angular momentum transfer is small $Δl=0$ and when the neutron-nucleus system is loosely bound.

description: We introduce two types of message passing algorithms for quantified Boolean formulas (QBF). The first type is a message passing based heuristics that can prove unsatisfiability of the QBF by assigning the universal variables in such a way that the remaining formula is unsatisfiable. In the second type, we use message passing to guide branching heuristics of a Davis-Putnam Logemann-Loveland (DPLL) complete solver. Numerical experiments show that on random QBFs our branching heuristics gives robust exponential efficiency gain with respect to the state-of-art solvers. We also manage to solve some previously unsolved benchmarks from the QBFLIB library. Apart from this our study sheds light on using message passing in small systems and as subroutines in complete solvers.

description: Malaria is one of the deadliest endemic diseases in developing countries with millions of cases recorded each year. In 2018, there were over 200 million malaria cases and over 400,000 deaths worldwide. Having widespread access to efficient malaria detection would help reduce malaria cases in these countries. In recent years, several computational algorithms have been applied to detect malaria from a variety of approaches, including analysis of blood smear images and presence of protein biomarkers in urine and saliva. For blood smear images, recent literature employs a combination of image segmentation techniques and machine learning classifiers. While multiple techniques have been suggested, and advances are being made, there is still work that needs to be done to identify the best combination of these algorithms. The aim of this study was to perform a comparative analysis of four different image segmentation techniques and five machine learning classifiers on a dataset of roughly 27,000 blood smear images, half of which were infected with malaria. The focus of the work involved identifying combinations of image segmentation and machine learning algorithms that resulted in the highest accuracy in classifying a blood smear image as infected or uninfected, leading to improved malaria detection. The Python programming language with the libraries OpenCV and Scikit-learn were used for the implementation of the computational algorithms developed in this work. The resulting confusion matrices helped to identify efficient combinations of image segmentation techniques and machine learning classifiers. Using a random forest classifier with binary thresholding resulted in the highest accuracy, with around 90%, but some other combinations also performed reasonably well. Our computational experiments also found that adaptive and K-means thresholding were not efficient, averaging slightly above 50% accuracy. The findings from this work provide an insight to identifying the best combination of an image segmentation technique and a machine learning classifier that can potentially be programmed into a future real-time mobile app that can be deployed in developing countries.

First-principles computed electronic and magnetic properties of zincblende alkaline-earth pnictides

description: Employing first-principle electronic structure calculations, we study the magnetic and electronic properties of the XY (X= Mg, Ca, Sr and Y= N, P, As, Sb) compounds crystallizing in the zincblende structure. The Ca and Sr alkaline-earth metal monopnictides are found to be half-metallic with a total spin magnetic moment per formula unit of 1.0 $μ_B$. In the case of the Mg alloys the p-d hybridization effect is much weaker and only MgN is a half-metal. Electron counting of the bands explains the Slater-Pauling behavior exhibited by the total spin magnetic moment. We also study for these alloys the effect of deformation taking into account both the cases of hydrostatic pressure and tetragonalization keeping constant either the in-plane lattice parameters or the unit cell volume. Even large degrees of deformation only marginally affect the electronic and magnetic properties of these alloys. Finally, we show that this stands also for the rocksalt structure. Our results suggest that alkaline-earth metal monopnictides are promising materials for magnetoelectronic applications.

description: Cirrhosis is a leading cause of mortality worldwide, affecting people of various incomes and diets. It has been discovered in various studies by Bajaj et al. that a person’s diet can affect cirrhosis indirectly by altering their gut microbiota. In fact, an increase in pathogenic bacteria present in the gut is often associated with disease progression. One of the factors affecting gut microbiota composition is diet, which varies among countries and cultures. In this study, we compared the effect of various diets on the severity of cirrhosis in patients from the United States, Mexico, and Turkey. The study includes patients with decompensated cirrhosis, compensated cirrhosis, and controls with no liver disease within each country. The Turkish diet consists of more probiotics and tea while the US participants with western diet consumed less fermented foods and had more coffee and soda; the Mexican diet, when compared to the American, consisted of lower protein and vegetable intake. Stool samples were collected from all three cohorts, sequenced using Ion Torrent technology, and analyzed using LEfSe, QIIME2, and MaAsLin pipelines. These results show that there is a difference in the gut microbiota among the participants in the various countries, and that diet does affect the microbiome. Understanding how diet affects cirrhosis can impact how the condition is treated, and prevented.

description: We investigate the physical properties and electronic structure of BaFe2-δSe3 crystals, which were grown out of tellurium flux. The crystal structure of the compound, an iron-deficient derivative of the ThCr2Si2-type, is built upon edge-shared FeSe4 tetrahedra fused into double chains. The semiconducting BaFe2-δSe3 with δ \approx 0.2 (ρ295K = 0.18 Ω\cdotcm and Eg = 0.30 eV) does not order magnetically, however there is evidence for short-range magnetic correlations of spin glass type (Tf \approx 50 K) in magnetization, heat capacity and neutron diffraction results. A one-third substitution of selenium with sulfur leads to a slightly higher electrical conductivity (ρ295K = 0.11 Ω\cdotcm and Eg = 0.22 eV) and a lower spin glass freezing temperature (Tf \approx 15 K), corroborating with higher electrical conductivity reported for BaFe2S3. According to the electronic structure calculations, BaFe2Se3 can be considered as a one-dimensional ladder structure with a weak interchain coupling.

description: Combining experiments and numerical simulations, we investigate the redistribution of quasi-momentum in a gas of atoms trapped in an optical lattice when the lattice depth is rapidly reduced. We find that interactions lead to significant momentum redistribution on millisecond timescales, thereby invalidating previous assumptions regarding adiabaticity. We show that this phenomenon is driven by the presence of low-momentum particle-hole excitations in an interacting system. Our results invalidate bandmapping as an equilibrium probe in interacting gases.

description: The stationary state of a single-atom (single-qubit) laser is shown to be a phase-averaged nonlinear coherent state - an eigenstate of a specific deformed annihilation operator. The solution found for the stationary state is unique and valid for all regimes of the single-qubit laser operation. We have found the parametrization of the deformed annihilation operator which provides superconvergence in finding the stationary state by iteration. It is also shown that, contrary to the case of the usual laser with constant Einstein coefficients describing transition probabilities, for the single-atom laser the interaction-induced transition probabilities effectively depend on the field intensity.

description: It is shown that if a bilinear map f: A x B --> C of modules over a commutative ring k is nondegenerate (i.e., if no nonzero element of A annihilates all of B, and vice versa), and A and B are Artinian, then A and B are of finite length. Some consequences are noted. Counterexamples are given to some attempts to generalize the above statement to balanced bilinear maps of bimodules over noncommutative rings, while the question is raised whether other such generalizations are true.

description: We demonstrate the effect of introducing controlled disorder in self-assembled three-dimensional photonic crystals. Disorders are induced through controlling the self-assembling process using an electrolyte of specific concentrations. Structural characterization reveals increase in disorder with increase in concentrations of the electrolyte. Reflectivity and transmittance spectra are measured to probe the photonic stop gap at different levels of disorder. With increase in disorder the stop gap is vanished and that results in a fully random photonic nanostructure where the diffuse scattered intensity reaches up to 100%. Our random photonic nanostructure is unique in which all scatters have the same size and shape. We also observe the resonant characteristics in the multiple scattering of light.

description: In the framework of a left-right model containing mirror fermions with gauge group SU(3)$_{C} \otimes SU(2)_{L} \otimes SU(2)_{R} \otimes U(1)_{Y^\prime}$, we estimate the neutrino masses, which are found to be consistent with their experimental bounds and hierarchy. We evaluate the decay rates of the Lepton Flavor Violation (LFV) processes $μ\rightarrow e γ$, $τ\rightarrow μγ$ and $τ\rightarrow eγ$. We obtain upper limits for the flavor-changing branching ratios in agreement with their present experimental bounds. We also estimate the decay rates of heavy Majorana neutrinos in the channels $N \rightarrow W^{\pm} l^{\mp}$, $N \rightarrow Z ν_{l}$ and $N \rightarrow H ν_{l}$, which are roughly equal for large values of the heavy neutrino mass. Starting from the most general Majorana neutrino mass matrix, the smallness of active neutrino masses turns out from the interplay of the hierarchy of the involved scales and the double application of seesaw mechanism. An appropriate parameterization on the structure of the neutrino mass matrix imposing a symmetric mixing of electron neutrino with muon and tau neutrinos leads to Tri-bimaximal mixing matrix for light neutrinos.

Distributionally Robust Optimization and its Applications in Portfolio Optimization

Subjects: Financial mathematics

description: We formulate a framework to solve the distributionally robust optimization problem. We allow the true probability measure to be inside a Wasserstein ball that is specified by the empirical data and the given confidence level. We transform the robust optimization into a non-robust optimization with a penalty term and provide an appropriate selection of the Wasserstein ambiguity set’s size. Then we apply the framework to some portfolio optimization problems, such as the mean-CVaR in risk management and the multiperiod mean-variance in portfolio management. Moreover, the numerical experiments of the US stock market showed the impressive results for our robust models compared to other popular strategies.

description: We present thirteen epochs of near-infrared (0.8-5 micron) spectroscopic observations of the pre-transitional, "gapped" disk system in SAO 206462 (=HD 135344B). In all, six gas emission lines (including Br gamma, Pa beta, and the 0.8446 micron line of O I) along with continuum measurements made near the standard J, H, K, and L photometric bands were measured. A mass accretion rate of approximately 2 x 10^-8 solar masses per year was derived from the Br gamma and Pa beta lines. However, the fluxes of these lines varied by a factor of over two during the course of a few months. The continuum also varied, but by only ~30%, and even decreased at a time when the gas emission was increasing. The H I line at 1.083 microns was also found to vary in a manner inconsistent with that of either the hydrogen lines or the dust. Both the gas and dust variabilities indicate significant changes in the region of the inner gas and the inner dust belt that may be common to many young disk systems. If planets are responsible for defining the inner edge of the gap, they could interact with the material on time scales commensurate with what is observed for the variations in the dust, while other disk instabilities (thermal, magnetorotational) would operate there on longer time scales than we observe for the inner dust belt. For SAO 206462, the orbital period would likely be 1-3 years. If the changes are being induced in the disk material closer to the star than the gap, a variety of mechanisms (disk instabilities, interactions via planets) might be responsible for the changes seen. The He I feature is most likely due to a wind whose orientation changes with respect to the observer on time scales of a day or less. To further constrain the origin of the gas and dust emission will require multiple spectroscopic and interferometric observations on both shorter and longer time scales that have been sampled so far.

description: This study utilized the data on abaca fiber production and used Holt-Winters model to forecast the abaca fiber production since the studied variable is characterized by a fairly strong intensity of seasonality. For the construction of forecasts, additive and multiplicative models were used. The most accurate forecasts were selected on the basis of Mean Square Error, Root Mean Square Error, Mean Absolute Percentage Error, and Mean Absolute Scaled Error. It was found that the multiplicative method had a higher accuracy, hence it was utilized to forecast the production for the next three years. According to the findings, the anticipated fiber production for 2021-2023 showed an increase up to the second quarter, but then declining afterwards.

description: We extend our previous three-dimensional, full-star simulations of the final hours of convection preceding ignition in Type Ia supernovae to higher resolution using the adaptive mesh refinement capability of our low Mach number code, MAESTRO. We report the statistics of the ignition of the first flame at an effective 4.34 km resolution, and general flow field properties at an effective 2.17 km resolution. We find that off-center ignition is likely, with radius of 50 km most favored and a likely range of 40 to 75 km. This is consistent with our previous coarser (8.68 km resolution) simulations, implying that we have achieved sufficient resolution in our determination of likely ignition radii. The dynamics of the last few hot spots preceding ignition suggest that a multiple ignition scenario is not likely. With improved resolution, we can more clearly see the general flow pattern in the convective region, characterized by a strong outward plume with a lower speed recirculation. We show that the convective core is turbulent with a Kolmogorov spectrum and has a lower turbulent intensity and larger integral length scale than previously thought (on the order of 16 km s$^{-1}$ and 200 km, respectively), and we discuss the potential consequences for the first flames.

Pseudo-Kähler Lie algebras with abelian complex structures

Subjects: subject: Differential Geometry (math.DG)

description: We study Lie algebras endowed with an abelian complex structure which admit a symplectic form compatible with the complex structure. We prove that each of those Lie algebras is completely determined by a pair (U,H) where U is a complex commutative associative algebra and H is a sesquilinear hermitian form on U which verifies certain compatibility conditions with respect to the associative product on U. The Riemannian and Ricci curvatures of the associated pseudo-Kähler metric are studied and a characterization of those Lie algebras which are Einstein but not Ricci flat is given. It is seen that all pseudo-Kähler Lie algebras can be inductively described by a certain method of double extensions applied to the associated complex asssociative commutative algebras.

description: Bibliography: p. 79-83.
description: The purpose of this study was to explore the relationship between fathers' perceptions of their family's functioning at the onset of therapy with the outcome of family therapy. This research used the Family Assessment Measure (Skinner, et al., 1983) to explore fathers' perceptions of their family's functioning at the beginning of family therapy; two raters assessed treatment outcome. Statistical analysis was used to determine whether scores on the F2M between "good outcome" and "poor outcome" groups differed significantly. The study also explored the influence of the following factors on Family Assessment Measure scores (Skinner, et al., 1983): father's age, the identified patient' s age and, and whether the father was the identified patient's biological father or stepfather. The results of the study suggest there are no particular perceptions of family functioning held by the father at the onset of therapy that are associated with the outcome of family therapy. However, the 'analysis of the possible mitigating factors revealed significant results.
Conformal frames and the validity of Birkhoff's theorem

description: Birkhoff's theorem is one of the most important statements of Einstein's general relativity, which generally can not be extended to modified theories of gravity. Here we study the validity of the theorem in scalar-tensor theories using a perturbative approach, and compare the results in the so-called Einstein and Jordan frames. The implications of the results question the physical equivalence between both frames, at least in perturbations.

description: We demonstrate broad-band reconfiguration of coupled photonic crystal nanobeam cavities by using optical gradient force induced mechanical actuation. Propagating waveguide modes that exist over wide wavelength range are used to actuate the structures and in that way control the resonance of localized cavity mode. Using this all-optical approach, more than 18 linewidths of tuning range is demonstrated. Using on-chip temperature self-referencing method that we developed, we determined that 20 % of the total tuning was due to optomechanical reconfiguration and the rest due to thermo-optic effects. Independent control of mechanical and optical resonances of our structures, by means of optical stiffening, is also demonstrated.

Mental Health Implications of Adolescent Scoliosis: Analysis of Current Practices and Proposal of a Mindfulness-Based Intervention

description: Scoliosis is a disease most often diagnosed during adolescence (normally between the ages of 12-17). The most common type of scoliosis diagnosed in this age range is adolescent idiopathic scoliosis (AIS). This type of scoliosis is idiopathic due to its manifestation without a known cause. During the adolescent stage of life, patients are dealing with normal pubescent stresses. A diagnosis of scoliosis adds another layer of burden as it requires managing the stigma of the physical scoliosis deformity and, oftentimes, treatment that includes a bulky orthotic back brace or corrective spine surgery. Patients experience scoliosis stigma that can affect self-esteem, self-worth, self-image, stress, anxiety, and social friendships. As such, patients may experience additional challenges to their mental well-being which can continue into their adult life even once the treatment has concluded. Current standards for scoliosis do not consider the negative mental health implications of the disease. An adjunctive intervention, specifically based on mindfulness, could teach patients with scoliosis to process these negative feelings and thoughts in a more positive way from the start of the treatment and aid the patients in their journey with scoliosis. Mindfulness skills could give them the tools to successfully overcome and/or experience the stressors in a less stressful way. Moreover, mindfulness-based interventions may also help to increase a patient's orthotic bracing treatment compliance which could aid in the overall improved progression of scoliosis.
Effects of Symmetry Energy in the Reaction 40Ca+124Sn at 140 MeV/nucleon

description: The density-dependent symmetry energy is a hot topic in nuclear physics. Many laboratories over the world are planning to perform related experiments to probe the symmetry energy. Based on the semiclassical Boltzmann-Uehling-Uhlenbeck (BUU) transport model, we study the effects of nuclear symmetry energy in the central reaction 40Ca+124Sn at 140MeV/nucleon in the laboratory system. It is found that the rapidity distribution of free nucleon's neutron-to-proton ratio is sensitive to the symmetry energy, especially at large rapidities. The free neutron-to-proton ratios at small or large rapidities may reflect high or low density behavior of nuclear symmetry energy. To probe the density dependence of nuclear symmetry energy, it is better to give the kinetic distribution and the rapidity distribution of emitted nucleons at the same time.

description: Second-order dissipative hydrodynamic equations for each component of a multi-component system are derived using the entropy principle. Comparison of the solutions with kinetic transport results demonstrates validity of the obtained equations. We demonstrate how the shear viscosity of the total system can be calculated in terms of the involved cross sections and partial densities. Presence of the inter-species interactions leads to a characteristic time-dependence of the shear viscosity of the mixture, which also means that the shear viscosity of a mixture cannot be calculated using the Green-Kubo formalism the way it has been done recently. This finding is of interest for understanding of the shear viscosity of a quark-gluon-plasme extracted from comparisons of hydrodynamic simulations with experimental results from RHIC and LHC.
