Price DOES Matter!: Modeling Price and Interest Preferences in Session-based Recommendation

Session-based recommendation aims to predict items that an anonymous user would like to purchase based on her short behavior sequence. The current approaches towards session-based recommendation only focus on modeling users' interest preferences, while they all ignore a key attribute of an item, i.e., the price. Many marketing studies have shown that the price factor significantly influences users' behaviors and the purchase decisions of users are determined by both price and interest preferences simultaneously. However, it is nontrivial to incorporate price preferences for session-based recommendation. Firstly, it is hard to handle heterogeneous information from various features of items to capture users' price preferences. Secondly, it is difficult to model the complex relations between price and interest preferences in determining user choices. To address the above challenges, we propose a novel method Co-guided Heterogeneous Hypergraph Network (CoHHN) for session-based recommendation. Towards the first challenge, we devise a heterogeneous hypergraph to represent heterogeneous information and rich relations among them. A dual-channel aggregating mechanism is then designed to aggregate various information in the heterogeneous hypergraph. After that, we extract users' price preferences and interest preferences via attention layers. As to the second challenge, a co-guided learning scheme is designed to model the relations between price and interest preferences and enhance the learning of each other. Finally, we predict user actions based on item features and users' price and interest preferences. Extensive experiments on three real-world datasets demonstrate the effectiveness of the proposed CoHHN. Further analysis reveals the significance of price for session-based recommendation.
THE FORMATION AND DYNAMICAL EVOLUTION OF YOUNG STAR CLUSTERS

Recent observations have revealed a variety of young star clusters, including embedded systems, young massive clusters, and associations. We study the formation and dynamical evolution of these clusters using a combination of simulations and theoretical models. Our simulations start with a turbulent molecular cloud that collapses under its own gravity. The stars are assumed to form in the densest regions in the collapsing cloud after an initial free-fall time of the molecular cloud. The dynamical evolution of these stellar distributions is continued by means of direct N-body simulations. The molecular clouds typical of the Milky Way Galaxy tend to form embedded clusters that evolve to resemble open clusters. The associations were initially considerably more clumpy, but they lost their irregularity in about a dynamical timescale, due to the relaxation process. The densest molecular clouds, which are absent in the Milky Way but are typical in starburst galaxies, form massive, young star clusters. They indeed are rare in the Milky Way. Our models indicate a distinct evolutionary path from molecular clouds to open clusters and associations or to massive star clusters. The mass–radius relation for both types of evolutionary tracks excellently matches the observations. According to our calculations, the time evolution of the half-mass–radius relation for open clusters and associations follows r h / pc = 2.7 ( t age / pc ) 2 / 3 ? > , whereas for massive star clusters r h / pc = 0.34 ( t age / Myr ) 2 / 3 ? > . Both trends are consistent with the observed age–mass–radius relation for clusters in the Milky Way.

Childhood trauma and suicide risk in hospitalized patients with schizophrenia: the sequential mediating roles of pandemic related post-traumatic stress symptoms, sleep quality, and psychological distress

Introduction Stressful global situation due to the COVID-19 pandemic caused a tremendous impact on mental health in hospitalized patients with schizophrenia. The mediating roles of psychological impact related to COVID-19, sleep quality, and psychological distress were investigated in the association between childhood trauma and suicidal risk in hospitalized patients with schizophrenia. Methods We analyzed cross-sectional data of 147 patients with schizophrenia and 189 healthy controls (HCs). Results Histories of childhood trauma and schizophrenia were good predictors of COVID-19-related psychological impact, global sleep quality, and psychological distress. Moreover, the series mediation model showed that the effect of childhood trauma on suicidal risk in hospitalized patients with schizophrenia was totally sequential mediated by the psychological impact of COVID-19, sleep quality, and psychological distress. Conclusion Clinicians need to recognize the increased suicidal risk associated with COVID-19-related psychological distress in schizophrenia patients with a history of childhood trauma.
People and Methodologies in Software Development

This thesis reports on research performed over a ten-year period, interviewing project teams, participating directly on projects, and reviewing proposals and case studies. The research addressed three questions relating to people and software development methodologies (Q1 through Q3), and produced six results (R1 through R6). Q1. Do we need yet another software development methodology, or can we expect a convergence and reduction at some point in time? Q2. If convergence, what must be the characteristics of the converged methodology? If no convergence, how can project teams deal with the growing number of methodologies? Q3. How does the methodology relate to the people on the project? R1. A methodology is a formula describing conventions of interaction between roles. R2. People's characteristics, which vary from person to person and even from moment to moment, form a first-order driver of the team's behavior and results. Such issues as how well they get along with each other and the fit (or misfit) of their personal characteristics with their job roles create significant, project-specific constraints on the methodology. This result indicates that people's personal characteristics place a limit on the effect of methodologies in general. R3. Every project needs a slightly different methodology, based on those people characteristics, the project's specific priorities, and the technologies being used. This result indicates that a team's methodology should be personalized to the team during the project and may even change during the project. R4. A set of principles were found that can be used to shape an effective methodology to the above constraints. These principles deal with the amount of coordination and verification required in the project, the trade-off between rework and serialization of work, and the trade-off between tacit and externalized knowledge in use by the team. R5. A technique was found to create a situationally specific methodology during the project and in time to serve the project, and to evolve it as the project progresses. R6. All the above suggests a repeating cycle of behavior to use on projects. 1. The members establish conventions for their interactions — a base methodology — at the start of the project. This can be likened to them "programming" themselves. 2. They then perform their jobs in the normal scurry of project life, often getting too caught up to reflect on how they are doing. 3. They schedule regular periods of reflection in which they reconsider and adjust their working conventions. These results have been used successfully on several industrial projects having the usual time and cost pressures on the staff.
Partial reactions of the Na,K-ATPase: determination of rate constants

Experiments were designed to characterize several partial reactions of the Na,K-ATPase and to demonstrate that a model can be defined that reproduces most of the transport features of the pump with a single set of kientic parameters. We used the fluorescence label 5- iodoacetamidofluorescein, which is thought to be sensitive to conformational changes, and the styryl dye RH 421, which can be applied to detect ion-binding and -release reactions. In addition transient electric currents were measured, which are associated mainly with the E1-->E2 conformational transition. Numerical simulations were performed on the basis of a reaction model, that has been developed from the Post- Albers cycle. Analysis of the experimental data allows the determination of several rate constants of the pump cycle. Our conclusions may be summarized as follows: (a) binding of one Na+ ion at the cytoplasmic face is electrogenic. This Na+ ion is specifically bound to a neutral binding site with an affinity of 8 mM in the presence of 10 mM Mg2+. In the absence of divalent cations, the intrinsic binding affinity was found to be 0.7 mM. (b) The analysis of fluorescence experiments with the cardiotonic steroid strophanthidin indicates that the 5-iodoacetamidofluorescein label monitors the conformational transition (Na3)E1-P-->P-E2(Na2), which is accompanied by the release of one Na+ ion. 5-IAF does not respond to the release of the subsequent two Na+ ions, which can be monitored by the RH 421 dye. These experiments indicate further that the conformational transition E1P-->P-E2 is the rate limiting process of the Na+ translocation. The corresponding rate constant was determined to be 22 s-1 at 20 degrees C. From competition experiments with cardiotonic steroids, we estimated that the remaining 2 Na+ ions are released subsequently with a rate constant of at least 5,000 s-1 from their negatively charged binding sites. (c) Comparing the fluorescence experiments with electric current transients, which were performed at various Na concentrations in the absence and presence of strophanthidin, we found that the transition (Na3). E1-P-->P-E2. (Na2) is the major charge translocating step in the reaction sequence Na3.E1-->(Na3). E1-P-->P-E2. (Na2)-->P-E2. The subsequent release of 2 Na+ ions contributed less than 25% to the total electric current transient. (d) The well known antagonism between cardiotonic steroids and K+ binding can be explained by a kinetic model. A quantitative description has been obtained under the assumption that these inhibitors bind only to the states P-E2(Na2) and P-E2(K2). (ABSTRACT TRUNCATED AT 400 WORDS)
The Prevalence, Distribution, and Effect of Pain Among Adolescents with Cerebral Palsy

Purpose: To describe the prevalence, distribution, and intensity of pain and determine the relationship between pain intensity and effect on daily activities in adolescents with cerebral palsy. Methods: A sample of 104 girls and 126 boys, mean ages 14.7 (SD = 1.7) and 14.8 (SD = 1.7) years, were asked “Have you experienced physical pain in the past month? ” Results: Sixty-four percent of girls and 50% of boys reported pain. Pain was most frequent in the feet and ankles, knees, and lower back of girls and boys at Gross Motor Function Classification System levels I to IV. Foot and ankle and knee pain were also frequent at level V. The Spearman rho value between intensity and effect on daily activities was 0.75 (p < 0.01) and 0.82 (p < 0.01) for girls and boys. Conclusions: The high prevalence of pain and its effect on daily activities suggests a need for greater focus on health promotion.

A Theory of Competition

WHO will deny that the character of a market depends on how much competition there is within it? Yet, after all these years, this elemental relation has not been incorporated into price theory. As Frank Knight used to remind us, in the theoretical regime of competition there is no competition. And, one may add, in the regime of monopoly there is none either. That leaves only the theory of oligopoly, where competitive behavior is used to explain why anything can happen. Some may argue that this is the way things should be, that injecting the competitive process into formal theory is to mix oil with water, since competition is an equilibrating force, a part of the dynamic process, while theory deals with states of equilibrium. Anyhow, they may say, the structural characteristics that ensure a particular equilibrium outcome in a given market also imply the dynamic process needed to establish it: if there are enough firms, a movement out of equilibrium will generate enough competition to equilibrate the market while eliminating itself in the course of doing so. Competition is latent in equilibrium, becoming active only in disequilibrium. But how many firms are enough? Theory gives no answer except "a large number. " A better answer can be found, we believe, by linking dynamic and static analysis together, and we shall suggest here an approach to this problem in the form of a rudimentary theory of the competitive process. We focus on price-cutting as a manifestation of competition and examine
Anterior colporrhaphy: a randomized trial of three surgical techniques.

OBJECTIVE The purpose of this study was to compare outcomes after anterior colporrhaphy with the use of 3 different surgical techniques. STUDY DESIGN One hundred fourteen women with anterior vaginal prolapse were randomly assigned to undergo anterior repair by one of 3 techniques: standard, standard plus polyglactin 910 mesh, or ultralateral anterior colporrhaphy. Before and after operation, patients underwent physical examination staging of prolapse; the International Continence Society system was used. Symptoms were assessed by questionnaire and visual analog scales. We defined "cure" as satisfactory (stage I) or optimal (stage 0) outcome at points Aa and Ba. RESULTS Of 114 patients who were originally enrolled, 109 patients underwent operation, and 83 patients (76%) returned for follow-up. Mean age (+/- SD) was 64.7 +/- 11.1 years. At entry, 7 patients (7%) had stage I anterior vaginal prolapse; 35 patients (37%) had stage II anterior vaginal prolapse; 51 patients (54%) had stage III anterior vaginal prolapse; and 2 patients (2%) had stage IV anterior vaginal prolapse. At a median length of follow-up of 23.3 months, 10 of 33 patients (30%) who were randomly assigned to the standard anterior colporrhaphy group experienced satisfactory or optimal anatomic results, compared with 11 of 26 patients (42%) with standard plus mesh and with 11 of 24 patients (46%) with ultralateral anterior colporrhaphy. The severity of symptoms that were related to prolapse improved markedly (preoperative score, 6.9 +/- 2.7; postoperative score, 1.1 +/- 0.8). Twenty-three of 24 patients (96%) no longer required manual pressure to void after operation. CONCLUSION These 3 techniques of anterior colporrhaphy provided similar anatomic cure rates and symptom resolution for anterior vaginal prolapse repair. The addition of polyglactin 910 mesh did not improve the cure rate compared with standard anterior colporrhaphy.

Biochemical proximates of pumpkin (Cucurbitaeae spp.) and their beneficial effects on the general well‐being of poultry species

There is a growing need to increase productivity in poultry. Growth hormones and antibiotics have the ability to improve health, weight gain and feed efficiency in meat-producing animals. The growth-promoting antibiotics are administered to poultry to improve the general performance of the chicken. However, the use of the xenobiotic drugs in food-producing animals has been a concern and a sensitive issue of debate for several decades in the EU and many other regional blocks of the world. Consequently, the use of hormones in animal production has been banned in Italy, Denmark and Germany for over 4-5 decades, while Belgium and Greece had never permitted its use for livestock fattening purposes. Bioactive phytochemicals exhibit antimicrobial, antioxidant, antiparasitic, antiprotozoal, antifungal and anti-inflammatory properties and consequently have several beneficial effects on appetite, growth and the immune status of the animal. In South Africa, different species of pumpkin are produced for food due to their high nutrient content. The flesh serves as a traditional food, while the seeds and peels are commonly discarded. Pumpkin seed extract is reported to be useful for immunomodulation, reproductive health, therapeutics over a wide range of disease conditions and stimulates metabolism of accumulated fats. Studies have also shown that pumpkin seeds are a valuable source of protein and fat. Their complexity and extent of bioactivity offers sustainable prospects for natural control of pathogenic/parasitic organisms, stimulate nutrition or enhance resistance to disease infections, and reduce abdominal fat and serum levels of harmful lipids, while increasing serum levels of beneficial lipids.

Network Densification in 5G: From the Short-Range Communications Perspective

Besides advanced telecommunications techniques, the most prominent evolution of wireless networks is the densification of network deployment. In particular, the increasing access point/ user density and reduced cell size significantly enhance spatial reuse, thereby improving network capacity. Nevertheless, does network ultra-densification and over-deployment always boost the performance of wireless networks? Since the distance from transmitters to receivers is greatly reduced in dense networks, signal is more likely to be propagated from long- to short-range distance. Without considering short-range propagation features, conventional understanding of network densification becomes doubtful. In this regard, it is imperative to reconsider the pros and cons brought by network densification. In this article, we first discuss the short-range propagation features in densely deployed networks and verify through experimental results the validity of the proposed short-range propagation model. Considering short-range propagation, we further explore the fundamental impact of network densification on network capacity, aided by which a concrete interpretation of ultra-densification is presented from the network capacity perspective. Meanwhile, as short-range propagation makes interference more complicated and difficult to handle, we discuss possible approaches to further enhance network capacity in ultra-dense wireless networks. Moreover, key challenges are presented to suggest future directions.
Dynamics of the Heme-binding Bacterial Gas-sensing Dissimilative Nitrate Respiration Regulator (DNR) and Activation Barriers for Ligand Binding and Escape*

Background: DNR is a recently discovered transcriptional regulator homologous to the CO sensor CooA. Results: NO binding to heme selectively allows activation; ligand dynamics energetics implies common mechanism for 6-coordinate heme proteins. Conclusion: DNR is an NO sensor acting as ligand trap. Significance: Demonstration of NO-sensing function helps unravel signaling in the pathogen P. aeruginosa and describes common mechanism in emerging class of 6-coordinate heme proteins. DNR (dissimilative nitrate respiration regulator) is a heme-binding transcription factor that is involved in the regulation of denitrification in Pseudomonas aeruginosa. In the ferrous deoxy state, the heme is 6-coordinate; external NO and CO can replace an internal ligand. Using fluorescence anisotropy, we show that high-affinity sequence-specific DNA binding occurs only when the heme is nitrosylated, consistent with the proposed function of DNR as NO sensor and transcriptional activator. This role is moreover supported by the NO “trapping” properties revealed by ultrafast spectroscopy that are similar to those of other heme-based NO sensor proteins. Dissociated CO-heme pairs rebind in an essentially barrierless way. This process competes with migration out of the heme pocket. The latter process is thermally activated (Ea ∼7 kJ/mol). This result is compared with other heme proteins, including the homologous CO sensor/transcription factor CooA, variants of the 5-coordinate mycobacterial sensor DosT and the electron transfer protein cytochrome c. This comparison indicates that thermal activation of ligand escape from the heme pocket is specific for systems where an external ligand replaces an internal one. The origin of this finding and possible implications are discussed.
