description: The characterization of quantum features in large Hilbert spaces is a crucial requirement for testing quantum protocols. In the continuous variables encoding, quantum homodyne tomography requires an amount of measurements that increases exponentially with the number of involved modes, which practically makes the protocol intractable even with few modes. Here we introduce a new technique, based on a machine learning protocol with artificial Neural Networks, that allows to directly detect negativity of the Wigner function for multimode quantum states. We test the procedure on a whole class of numerically simulated multimode quantum states for which the Wigner function is known analytically. We demonstrate that the method is fast, accurate and more robust than conventional methods when limited amounts of data are available. Moreover the method is applied to an experimental multimode quantum state, for which an additional test of resilience to losses is carried out.
The effects of taste aversion conditioning upon delayed taste discrimination learning

description: In 1982, Westbrook and Homewood reported that pairing a taste with poison augmented acquisition of subsequent delayed taste aversions. They predicted, however, that an increase in the associability of tastes was limited to tastes paired with illness and would not affect the associability of tastes predictive of some other event. To test this prediction it was first necessary to demonstrate that a conditioned aversive taste could serve as a discriminative stimulus for a water reinforcer in an operant taste discrimination (Experiment 1). Experiment 2 demonstrated that pairing the taste stimulus with poison had no effect on performance of the delayed taste discrimination. The results support the prediction that changes in the associability of a stimulus may be reinforcer-specific.

description: A cohomology class of a smooth complex variety of dimension $n$ has coniveau $\geq c$ if it vanishes in the complement of a closed subvariety of codimension $\geq c$, and has strong coniveau $\geq c$ if it comes by proper pushforward from the cohomology of a smooth variety of dimension $\leq n-c$. We show that these two notions differ in general, both for integral classes on smooth projective varieties and for rational classes on smooth open varieties.

description: An effective Hamiltonian is derived for two coupled three-Josephson-junction (3JJ) qubits. This is not quite trivial, for the customary "free" 3JJ Hamiltonian is written in the limit of zero inductance L. Neglecting the self-flux is already dubious for one qubit when it comes to readout, and becomes untenable when discussing inductive coupling. First, inductance effects are analyzed for a single qubit. For small L, the self-flux is a "fast variable" which can be eliminated adiabatically. However, the commonly used junction phases are_not_ appropriate "slow variables", and instead one introduces degrees of freedom which are decoupled from the loop current to leading order. In the quantum case, the zero-point fluctuations (LC oscillations) in the loop current diverge as L->0. Fortunately, they merely renormalize the Josephson couplings of the effective (two-phase) theory. In the coupled case, the strong zero-point fluctuations render the full (six-phase) wave function significantly entangled in leading order. However, in going to the four-phase theory, this uncontrollable entanglement is integrated out completely, leaving a computationally usable mutual-inductance term of the expected form as the effective interaction.

description: This paper proposes an integrative approach to feature (input and output) selection in Data Envelopment Analysis (DEA). The DEA model is enriched with zero-one decision variables modelling the selection of features, yielding a Mixed Integer Linear Programming formulation. This single-model approach can handle different objective functions as well as constraints to incorporate desirable properties from the real-world application. Our approach is illustrated on the benchmarking of electricity Distribution System Operators (DSOs). The numerical results highlight the advantages of our single-model approach provide to the user, in terms of making the choice of the number of features, as well as modeling their costs and their nature.

Weight gain in breast cancer patients receiving adjuvant treatment as a function of restraint, disinhibition, and hunger
Creators: name: Degeorge, Donna
Publisher: name: American University
Year: 2023

description: Weight gain during and following adjuvant chemotherapy (Group A), adjuvant tamoxifen (Group B), and radiation therapy (Group C) was studied in a total of 73 subjects an average of 20 months after surgical treatment for breast cancer. Subjects were interviewed individually and administered the Three-Factor Eating Questionnaire, which assessed eating behavior along three dimensions: dietary restraint, disinhibition, and perceived hunger. Questionnaires were also given which assessed emotional status, psychological adjustment to illness, and body image. Weight data was obtained from medical records and a current weight obtained at the time of interview. Although it was predicted that restrained eaters in Group A would gain the most weight, there were no significant differences found in weight gain between groups. Restraint predicted weight gain in women across groups who had gained 2 or more kg for the first 6 months beginning the first day of treatment. However, after 6 months, both disinhibition and hunger appeared to predict weight gain. Disinhibition and hunger were also associated with a heavier weight at baseline. Decrease in activity level was also found to be correlated with weight gain. There was no direct association between weight gain and any of the psychological variables or change in menopausal status during treatment. However, both disinhibition and hunger were associated with negative body image and some measures of dysphoria, suggesting that psychological variables may be mediators of weight gain in this setting. These findings suggest that weight gain is not mediated by some metabolic effect of chemotherapy per se, but that women treated for breast cancer by each of these modalities may gain weight both during and after treatment. Rather, the data suggest that particular traits with regard to eating behavior may predispose some women to gain weight while undergoing or recovering from treatment for breast cancer. No differences were found between groups on body image, emotional status, or psychological adjustment to illness. Scores on questionnaires were consistent with patient interviews. Although many subjects experienced some day-to-day problems as a result of breast cancer, such as fitting prostheses, most subjects appeared to have recovered from their earlier emotional disequilibrium. A universal concern in all groups was fear of recurrence. (Abstract shortened with permission of author.).

description: The effect of mixture lengths of vehicles on the asymmetric exclusion model is studied using numerical simulations for both open and periodic boundaries in parallel dynamics. Densities are calculated as a function of the injecting rates $\alpha1$ and $\alpha2$ of vehicles type 1 and type 2 respectively, and the phase diagram ($\alpha1$,$\alpha2$) is presented for a fixed value of the extracting rate $β$. In this case the first order transition from low to high density phases occurs at $\alpha1+\alpha2=β$ and disappears for $\alpha2>β$. While, in the case of one entry the gap which is a characteristic of the first order transition vanishes with increasing $α$ for n $\neq 0$.However, the first order transition between high and low densities exhibit an end point above which the global density undergoes a continuous passage. The end point coordinate depends strongly on the value of n. In the periodic boundaries case, the presence of vehicles type2 in the chain leads to a modification in the fundamental phase diagram (current, density). Indeed, the maximal current value decreases with increasing the concentration of vehicles type 2, and occurs at higher values of the global density in contrast with what was found by Schadschneider et al \cite{20}.

description: Bimetric theory describes a massless and a massive spin-2 field with fully non-linear (self-)interactions. It has a rich phenomenology and has been successfully tested with several data sets. However, the observational constraints have not been combined in a consistent framework, yet. We propose a parametrization of bimetric solutions in terms of the effective cosmological constant $Λ$ and the mass $m_\mathrm{FP}$ of the spin-2 field as well as its coupling strength to ordinary matter $\barα$. This simplifies choosing priors in statistical analysis and allows to directly constrain these parameters with observational data not only from local systems but also from cosmology. By identifying the physical vacuum of bimetric theory these parameters are uniquely determined. We work out the dictionary for the new parametrization for various submodels and present the implied consistency constraints on the physical parameter space. We then apply the dictionary to derive observational constraints from SN1a on the physical parameters. As a result we find that even self-accelerating models with a heavy spin-2 field are in perfect agreement with current supernova data.

description: A Machine can only learn if it is biased in some way. Typically the bias is supplied by hand, for example through the choice of an appropriate set of features. However, if the learning machine is embedded within an {\em environment} of related tasks, then it can {\em learn} its own bias by learning sufficiently many tasks from the environment. In this paper two models of bias learning (or equivalently, learning to learn) are introduced and the main theoretical results presented. The first model is a PAC-type model based on empirical process theory, while the second is a hierarchical Bayes model.

description: Historians, political scientists, journalists, politicians, and presidents have criticized today's press for placing too much emphasis on personal news about the president. Critics say presidential news coverage increasingly centers on the man's personality and personal trivia. This quantitiative study challenges the criticism by exploring personal news coverage of the twentieth century's fifteen presidents. The study was designed to determine if personal news about recent presidents has accounted for a larger portion of presidential news coverage. Secondary purposes were to determine which presidents have received the most and the least personal coverage and to identify factors that have influenced the amount of personal news coverage presidents receive. Data were collected from a two-year sample period of each man's presidency. The four major newspapers studied--New York Times, Los Angeles Times, St. Louis Post-Dispatch, and Atlanta Constitution--give the study a national perspective while representing different political leanings. Results show that, contrary to general impressions, early twentieth-century presidents received a higher percentage of personal news than have recent presidents. Data show personal stories represented the following percentages of news coverage: T. Roosevelt, 51; Wilson, 24; Harding, 22; F. Roosevelt, 16; Coolidge, 15: Kennedy, 14; Truman and Johnson, 12; Reagan and Taft, 11; Carter, 10; Ford, 9; Hoover, 8; Eisenhower, 7; and Nixon, 5. Regression analysis procedures used the aggregate data for all the presidents to define a trend toward less personal coverage of presidents. The regression coefficient was found to be $-$.26. Factors identified as influencing the magnitude of a president's personal news coverage are: how early in the century he serves, how newsworthy his personality and personal life are, and how willing he is to provide the press with liberal access to the White House and to him. The study concludes that newspapers are wrongly perceived as being preoccupied with personal coverage from the White House because television news constantly airs footage depicting trivial activities of the president. Another conclusion is that today's major newspapers are created, with regard to personal coverage from the White House, with a higher degree of professionalism than those of the past; they place very few personal stories about the president on their front page.

description: Quantum mechanical fluctuations in an interval give rise to the Casimir effect, which destabilizes the size of the interval. This can be problematic in constructing Kaluza-Klein theories. We consider the possibility that a breakdown of the Poincaré symmetry in an extra dimension can solve this instability problem. As a specific example, we consider the space-time with a $κ$-deformed Poincaré algebra, calculate the Casimir force between two plates, and find that we can have an interval with a stable size.

description: Severe maternal morbidity underestimates the incidence of other, route-specific International Classification of Diseases Version 10 coded delivery complications.
description: OBJECTIVE: Although maternal morbidity has been increasing in recent years, quality measures for maternal outcomes of childbirth hospitalizations remain controversial. Previous studies have relied upon International Classification of Diseases (ICD-9) coding with virtually no literature on how the 2015 transition to ICD-10 has affected delivery complication rates. This study describes the incidence of maternal obstetric complications in Illinois using ICD10 coding algorithms. METHODS: In a retrospective cohort study of all deliveries at 127 Illinois hospitals from January 2016 to December 2018, ICD-10 codes were used to characterize severe maternal morbidity (SMM) and other delivery route-specific complications of vaginal and cesarean delivery. Poisson regression models were used to estimate the association of maternal sociodemographic and clinical characteristics as well as hospital characteristics with the likelihood of complications.RESULTS: Among 421,426 deliveries, the SMM rate was 0.76% overall, 0.44% for vaginal and 1.50% for cesarean delivery. Other maternal complications occurred in 8.62% of vaginal and 9.96% of cesarean deliveries. Patient age, race and ethnicity, and pre-existing and pregnancy-related clinical conditions were significantly associated with each outcome. Hospital-annual delivery volume, weekend admission and medical record coding intensity, measured by the mean number of ICD-10 codes for uncomplicated deliveries, were also significantly associated with complication incidence.CONCLUSION: SMM significantly underestimates the incidence of other potentially preventable complications. Complication incidence is higher for women from racial and ethnic minority groups and high poverty neighborhoods. However, the association of the likelihood of complications with hospital coding intensity and post-hoc analyses of length of stay differences between complicated and uncomplicated deliveries raise questions about the reliability of ICD-10 coding, which is incommensurate with previous ICD-9 research. New risk adjusted outcome measures based on detailed clinical data and linked antepartum and postpartum care will be necessary to improve obstetric quality of care.

The experimental group subjects were 1982-83 alumni of the Saturday Academy Program. This program is located on the Van Ness Campus of the University of the District of Columbia. The control group subjects had the same profile as the experimental group subjects with respect to age and school performance. For each of the three variables in this study confidence intervals (alpha =.05)were calculated for the difference between proportions using the following data sets: (i) total experimental group vs. total control group; (ii) experimental males vs. control males; (iii) experimental females vs. control females; (iv) experimental males vs. experimental females; (v) control males vs. control females; (vi) total males vs. total females. With respect to each variable, the results of this study regarding the impact of program participation indicate that there exist: (i) a significant difference between total experimental and total control group members; (ii) although the difference between experimental females and control females was significant it was less pronounced than the significant difference between experimental males and control males on all three variables. The difference between the total male population and the total female population was not significant with respect to high school graduation rates, rate of college enrollment or selection of a quantitative major. The secondary purpose of this research was to provide a description of the Saturday Academy Program. To carry out this secondary purpose, parents (or guardians) of current participants, participants and program teachers were asked to complete questionnaires. Administrative personnel were interviewed and project reports were examined. Recommendations were made based on the results of these findings.

description: For the Convolutional Neural Networks (CNNs) applied in the intelligent diagnosis of gastric cancer, existing methods mostly focus on individual characteristics or network frameworks without a policy to depict the integral information. Mainly, Conditional Random Field (CRF), an efficient and stable algorithm for analyzing images containing complicated contents, can characterize spatial relation in images. In this paper, a novel Hierarchical Conditional Random Field (HCRF) based Gastric Histopathology Image Segmentation (GHIS) method is proposed, which can automatically localize abnormal (cancer) regions in gastric histopathology images obtained by an optical microscope to assist histopathologists in medical work. This HCRF model is built up with higher order potentials, including pixel-level and patch-level potentials, and graph-based post-processing is applied to further improve its segmentation performance. Especially, a CNN is trained to build up the pixel-level potentials and another three CNNs are fine-tuned to build up the patch-level potentials for sufficient spatial segmentation information. In the experiment, a hematoxylin and eosin (H&E) stained gastric histopathological dataset with 560 abnormal images are divided into training, validation and test sets with a ratio of 1 : 1 : 2. Finally, segmentation accuracy, recall and specificity of 78.91%, 65.59%, and 81.33% are achieved on the test set. Our HCRF model demonstrates high segmentation performance and shows its effectiveness and future potential in the GHIS field.

description: A systematic method to fabricate porous silicon one dimensional photonic crystals has been engineered to have a photonic bandwidth up to 2000nm. The observation of the tailorability of the photonic bandgap (PBG) underscores the requirement of the large refractive index contrast for making broad PBG structures. In this letter, we present the fabrication and characteristics of such structures that may be promising structures for a large variety of applications.

description: We review the status as regards the existence of three- and four-body bound states made of neutrons and $Λ$ hyperons. For interesting cases, the coupling to neutral baryonic systems made of charged particles of different strangeness has been addressed. There are strong arguments showing that the $Λnn$ system has no bound states. $ΛΛnn$ strong stable states are not favored by our current knowledge of the strangeness $-1$ and $-2$ baryon-baryon interactions. However, a possible $Ξ^- t$ quasibound state decaying to $ΛΛnn$ might exist in nature. Similarly, there is a broad agreement about the nonexistence of $ΛΛn$ bound states. However, the coupling to $ΞNN$ states opens the door to a resonance above the $ΛΛn$ threshold.

description: Polycyclic aromatic hydrocarbons (PAHs) are pervasive and persistent pollutants in contaminated soil, posing a severe health and environmental threat. Enzymatic bioremediation presents a viable solution for the remediation of PAH-contaminated soil. In this study, a recombinant laccase with the encoding gene originating from Trametes villosa and recombinantly expressed in Aspergillus oryzae, designated as TVL, was discovered to possess strong PAH reduction capabilities. The specific enzyme activity of TVL was 73485 and 5102 LAMU/g enzyme protein at pH 5.0/7.0 and 37°C. Furthermore, it exhibited significant benzo[a]pyrene degradation, with 100% and 90.48% degradation at pH 5.0/7.0 after 24 h in the liquid phase. The degradation process of benzo[a]pyrene in soil was thoroughly investigated. Optimal conditions were identified as 15 mg/g NK-BSoil-3 and 1.35 mg/g HBT, resulting in a removal rate of 37.54% within 7 days when 0.01 U/g of TVL was applied. The potential mechanisms were investigated using molecular docking simulation. The binding energy between benzo[a]pyrene and TVL protein is notably robust, suggesting a higher propensity for enzyme binding. The TVL protein pocket contains nine amino acids that can interact most strongly with benzo[a]pyrene. Consequently, the recombinant laccase TVL holds considerable practical significance in bioremediation.

description: We explicitly construct the holographic dual configuration for the four dimensional $\mathcal{N}=4$ superconformal block containing half-BPS scalar primary operators by considering its full $AdS_5 \times S^5$ dual geometry. We extend the embedding space formalism and the related Harmonic analysis to general $d$-dimensional sphere $S^d$, and obtain precisely the $R$-symmetry contribution to the half-BPS scalar superconformal blocks, which we refer as "$R$-symmetry block". We also observe that the $R$-symmetry quadratic Casimir operator can be mapped to BC$_{2}$ Calogero-Sutherland system Hamiltonian, such that $R$-symmetry block is in terms identified as its bound state wave function.

High Resolution X-ray Spectroscopy of the Fe K complex in IC 4329A

description: We report the detection of complex Fe K line emission from a Chandra High Energy Transmission Grating Spectrometer observation of the Seyfert 1 galaxy IC 4329A. The line emission is double-peaked, one peak centered at ~6.3 keV, and the other at ~6.9 keV in the source rest frame. When modeled by Gaussians, the lower energy peak is resolved by the HEG at >99% confidence, whilst the higher energy peak is resolved at only <90% confidence. The best-fitting widths are \~21,000km/s and ~4000km/s FWHM for the ~6.3 keV and ~6.9 keV peaks respectively. If the peaks correspond to two distinct emission lines, then the peak energies are redshifted with respect to the expected line energies of Fe I Ka and Fe XXVI Lya by at least 650 km/s and 950 km/s respectively. Alternatively, the Fe K line profile may be due to a single line from a relativistic accretion disk. In that case the inclination angle of the disk is required to be 24^{+9}_{-1} degrees, the outer radius constrained to several tens of gravitational radii, and the radial line emissivity flatter than r^{-0.7}. Another possibility is that both peaks are due to distinct lines but each one relativistically broadened by a disk. In that case the lower energy peak could correspond to emission from Fe in a low ionization state, and the high-energy peak to Fe XXVI Lya emission. Then, the inclination angle is even less, restricted to a few degrees. However, the radial emissivity law is allowed to be steeper (~r^{-2.5}) and the outer radius does not have to be fine-tuned. Yet another scenario is that the lower energy peak originates in a disk but the higher energy peak originates in more distant matter.

description: The aim of this investigation is to prepare geopolymer cement by mixing various amounts of granulated blast furnace slag (GBFS) with Fly ash (FA) and cement kiln dust (CKD). Seven blends are prepared using 100 % slag , 95% slag+5% CKD or fly ash , 90% slag + 10% CKD or Fly ash and 85% slag + 15% CKD or Fly ash . The dry mixes with the different mixing ratios are activated by the alkaline activator (AA) 6% sodium hydroxide solution and 10% by volume liquid sodium silicate, the w/s ratio used is 0.24. The pastes are moulded into 1 inch cubic moulds and left within the moulds at 100% relative humidity for 24 hrs, then demoulded and cured under tap water for 1,3,7,28,90 and 180 days. At each hydration time, compressive strength, combined water , bulk density , total porosity are determined . X-ray diffraction measurements showed CSH as the main hydration constituent of the geopolymer structure being amorphous and glass-like. The results indicate that the mix containing 85% slag + 15% fly ash give the best physico chemical and mechanical properties of geopolymer cement .

description: The formation of shocks within the solar atmosphere remains one of the few observable signatures of energy dissipation arising from the plethora of magnetohydrodynamic waves generated close to the solar surface. Active region observations offer exceptional views of wave behavior and its impact on the surrounding atmosphere. The stratified plasma gradients present in the lower solar atmosphere allow for the potential formation of many theorized shock phenomena. In this study, using chromospheric Ca II 854.2nm spectropolarimetric data of a large sunspot, we examine fluctuations in the plasma parameters in the aftermath of powerful shock events that demonstrate polarimetric reversals during their evolution. Modern inversion techniques are employed to uncover perturbations in the temperatures, line-of-sight velocities, and vector magnetic fields occurring across a range of optical depths synonymous with the shock formation. Classification of these non-linear signatures is carried out by comparing the observationally-derived slow, fast, and Alfvén shock solutions to the theoretical Rankine-Hugoniot relations. Employing over 200,000 independent measurements, we reveal that the Alfvén (intermediate) shock solution provides the closest match between theory and observations at optical depths of log(tau) = -4, consistent with a geometric height at the boundary between the upper photosphere and lower chromosphere. This work uncovers first-time evidence of the manifestation of chromospheric intermediate shocks in sunspot umbrae, providing a new method for the potential thermalization of wave energy in a range of magnetic structures, including pores, magnetic flux ropes, and magnetic bright points.
