description: Most existing recommender systems represent a user's preference with a feature vector, which is assumed to be fixed when predicting this user's preferences for different items. However, the same vector cannot accurately capture a user's varying preferences on all items, especially when considering the diverse characteristics of various items. To tackle this problem, in this paper, we propose a novel Multimodal Attentive Metric Learning (MAML) method to model user diverse preferences for various items. In particular, for each user-item pair, we propose an attention neural network, which exploits the item's multimodal features to estimate the user's special attention to different aspects of this item. The obtained attention is then integrated into a metric-based learning method to predict the user preference on this item. The advantage of metric learning is that it can naturally overcome the problem of dot product similarity, which is adopted by matrix factorization (MF) based recommendation models but does not satisfy the triangle inequality property. In addition, it is worth mentioning that the attention mechanism cannot only help model user's diverse preferences towards different items, but also overcome the geometrically restrictive problem caused by collaborative metric learning. Extensive experiments on large-scale real-world datasets show that our model can substantially outperform the state-of-the-art baselines, demonstrating the potential of modeling user diverse preference for recommendation.

description: Проаналізовано особливості механізму регулювання розвитку вітчизняного аграрного сектору економіки. Зазначено, що в Україні механізм державної фінансової підтримки аграрного сектору економіки залишається вкрай неефективним і не сприяє вирішенню тих проблем, що постають на сучасному етапі розвитку. Визначено, що реалізація завдань державної фінансової підтримки сільськогосподарського комплексу повинна забезпечити: формування ефективного власника в сільському господарстві; створення сприятливих економічних умов для діяльності суб'єктів господарювання на аграрному ринку; зростання обсягів виробництва сільськогосподарської продукції та підвищення його ефективності. Зауважено, що однією з проблем здійснення державної фінансової підтримки сільськогосподарського комплексу є те, що вона не забезпечує очікуваного ефекту щодо подальшого розвитку зазначеного комплексу, оскільки не концентрується на пріоритетних напрямах, а розподіляється серед значної кількості товаровиробників, не створюючи умови для забезпечення розширеного відтворення. Історичні ресурси України в галузі сільського господарства, а також його законодавча та нормативна база для державно-приватного партнерства (ДПП) – це важливий фундамент для розширення та вдосконалення конкурентоспроможності сільського господарства країни через ДПП. Здійснено оцінювання досвіду роботи ДПП у сільському господарстві та надано рекомендації щодо можливостей удосконалення механізму державної фінансової підтримки аграрного сектору економіки України через впровадження ДПП.

description: The cubic chiral helimagnets with the $P2_13$ space group represent a group of compounds in which the stable skyrmion-lattice state is experimentally observed. The key parameter that controls the energy landscape of such systems and determines the emergence of a topologically nontrivial magnetic structures is the Dzyaloshinskii-Moriya interaction (DMI). Chemical substitution is recognized as a convenient instrument to tune the DMI in real materials and has been successfully utilized in studies of a number of chiral magnets, such as MnSi, FeGe, MnGe, and others. In our study, we applied small-angle neutron scattering to investigate how chemical substitution influences the skyrmionic properties of an insulating helimagnet Cu$_2$OSeO$_3$ when Cu ions are replaced by either Zn or Ni. Our results demonstrate that the DMI is enhanced in the Ni-substituted compounds (Cu,Ni)$_2$OSeO$_3$, but weakened in (Cu,Zn)$_2$OSeO$_3$. The observed changes in the DMI strength are reflected in the magnitude of the spin-spiral propagation vector and the temperature stability of the skyrmion phase.

description: The Einstein evolution equations are studied in a gauge given by a combination of the constant mean curvature and spatial harmonic coordinate conditions. This leads to a coupled quasilinear elliptic--hyperbolic system of evolution equations. We prove that the Cauchy problem is locally strongly well--posed and that a continuation principle holds. For initial data satisfying the Einstein constraint and gauge conditions, the solutions to the elliptic-hyperbolic system defined by the gauge fixed Einstein evolution equations are shown to give vacuum spacetimes.

description: A search for events with a high energy isolated electron or muon and missing transverse momentum has been performed at the electron-proton collider HERA using an integrated luminosity of 13.6 pb-1 in e-p scattering and 104.7 pb-1 in e+p scattering. Within the Standard Model such events are expected to be mainly due to W boson production with subsequent leptonic decay. In e-p interactions one event is observed in the electron channel and none in the muon channel, consistent with the expectation of the Standard Model. In the e+p data a total of 18 events are seen in the electron and muon channels compared to an expectation of 12.4 \pm 1.7 dominated by W production (9.4 \pm 1.6). Whilst the overall observed number of events is broadly in agreement with the number predicted by the Standard Model, there is an excess of events with transverse momentum of the hadronic system greater than 25 GeV with 10 events found compared to 2.9 \pm 0.5 expected. The results are used to determine the cross section for events with an isolated electron or muon and missing transverse momentum.

description: Background: A previously performed phase III trial on 112 subjects investigating prophylactic nimodipine treatment in vestibular schwannoma (VS) surgery showed no clear beneficial effects on preservation of facial and cochlear nerve functions, though it should be considered that protection of facial nerve function was the primary outcome. However, the risk for postoperative hearing loss was halved in the nimodipine group compared to the control group (OR 0.49; 95% CI 0.18–1.30; p = 0.15). Accordingly, this phase III extension trial investigates the efficacy and safety of prophylactic nimodipine for hearing preservation in VS surgery. Methods: This is a randomized, multi-center, two-armed, open-label phase III trial with blinded expert review and two-stage with interim analysis. Three hundred thirty-six adults with the indication for microsurgical removal of VS (Koos I–IV) and serviceable preoperative hearing (Gardner-Robertson scale (GR) 1–3) are assigned to either the therapy (intravenous nimodipine 1–2 mg/h from the day before surgery until the fifth postoperative day and standard of care) or the control group (surgery only and standard of care). The primary endpoint of the trial is postoperative cochlear nerve function measured before discharge according to GR 1–3 versus GR 4–5 (binary). Hearing function will be determined by pre- and postoperative audiometry with speech discrimination, which will be evaluated by a blinded expert reviewer. Furthermore, patient-reported outcomes using standardized questionnaires will be analyzed. Discussion: Prophylactic parenteral nimodipine treatment may have a positive effect on hearing preservation in VS surgery and would improve patient’s quality of life. Further secondary analyses are planned. Except for dose-depending hypotension, nimodipine is known as a safe drug. In the future, prophylactic nimodipine treatment may be recommended as a routine medication in VS surgery. VS can be considered as an ideal model for clinical evaluation of neuroprotection, since hearing outcome can be classified by well-recognized criteria. The beneficial effect of nimodipine may be transferable to other surgical procedures with nerves at risk and may have impact on basic research.

description: The level of residentiary employment in areas such as counties is an important component of rural development, environmental, and energy impact analysis. Volatile employment changes lead to migration, population, and wage changes. This study demonstrates a procedure for estimating disaggregated and lagged economic base multipliers for short to intermediate term forecasting models. Using an application of pooled cross-section/time-series data, a covariance model and an error components model are demonstrated for Northern Great Plains coal development. The only sector identified as having a consistent time lag was mining, and this lag was estimated to be 1 year.

description: In this paper, we study an energy efficiency maximization problem in uplink for D2D communications underlaid with cellular networks on multiple bands. Utilizing stochastic geometry, we derive closed-form expressions for the average sum rate, successful transmission probability, and energy efficiency of cellular and D2D users. Then, we formulate an optimization problem to jointly maximize the energy efficiency of D2D and cellular users and obtain optimum transmission power of both D2D and cellular users. In the optimization problem, we guarantee the QoS of users by taking into account the success transmission probability on each link. To solve the problem, first we convert the problem into canonical convex form. Afterwards, we solve the problem in two phases, energy efficiency maximization of devices and energy efficiency maximization of cellular users. In the first phase, we maximize the energy efficiency of D2D users and feed the solution to the second phase where we maximize the energy efficiency of cellular users. Simulation results reveal that significant energy efficiency can be attained e.g., 10% energy efficiency improvement compared to fix transmission power in high density scenario.

description: We study diagrams associated with a finite simplicial complex K, in various algebraic and topological categories. We relate their colimits to familiar structures in algebra, combinatorics, geometry and topology. These include: right-angled Artin and Coxeter groups (and their complex analogues, which we call circulation groups); Stanley-Reisner algebras and coalgebras; Davis and Januszkiewicz's spaces DJ(K) associated with toric manifolds and their generalisations; and coordinate subspace arrangements. When K is a flag complex, we extend well-known results on Artin and Coxeter groups by confirming that the relevant circulation group is homotopy equivalent to the space of loops $ΩDJ(K)$. We define homotopy colimits for diagrams of topological monoids and topological groups, and show they commute with the formation of classifying spaces in a suitably generalised sense. We deduce that the homotopy colimit of the appropriate diagram of topological groups is a model for $ΩDJ(K)$ for an arbitrary complex K, and that the natural projection onto the original colimit is a homotopy equivalence when K is flag. In this case, the two models are compatible.

description: The tilt of bipolar magnetic region (BMR) is crucial in the Babcock--Leighton process for the generation of the poloidal magnetic field in Sun. Based on the thin flux tube model of the BMR formation, the tilt is believed to be caused by the Coriolis force acting on the rising flux tube of the strong toroidal magnetic field from the base of the convection zone (BCZ). We analyze the magnetic field dependence of BMR tilts using the magnetograms of Michelson Doppler Imager (MDI) (1996-2011) and Helioseismic and Magnetic Imager (HMI) (2010-2018). We observe that the distribution of the maximum magnetic field ($B_{\rm max}$) of BMRs is bimodal. Its first peak at the low field corresponds to BMRs which do not have sunspots as counterparts in the white light images, whereas the second peak corresponds to sunspots as recorded in both types of images. We find that the slope of Joy's law ($γ_0$) initially increases slowly with the increase of $B_{\rm max}$. However, when $B_{\rm max} \gtrsim 2$ kG, $γ_0$ decreases. Scatter of BMR tilt around Joy's law systematically decreases with the increase of $B_{\rm max}$. The decrease of observed $γ_0$ with $B_{\rm max}$ provides a hint to a nonlinear tilt quenching in the Babcock--Leighton process. We finally discuss how our results may be used to make a connection with the thin flux tube model.

We show that the solutions can be generated from their data at the initial singularity and present the formal general solution for arbitrary initial data. We exemplify the method by constructing the Kantowski-Sachs cosmological model and a generalization of it that corresponds to an unpolarized $T^3$ Gowdy model.

description: CRISPR technologies comprising a Cas nuclease and a guide RNA (gRNA) can utilize multiple gRNAs to enact multi-site editing or regulation in the same cell. Nature devised a highly compact means of encoding gRNAs in the form of CRISPR arrays composed of conserved repeats separated by targeting spacers. However, the capacity to acquire new spacers keeps the arrays longer than necessary for CRISPR technologies. Here, we show that CRISPR arrays utilized by the Cas9 nuclease can be shortened without compromising and sometimes even enhancing targeting activity. Using multiplexed gene repression in E. coli, we found that each region could be systematically shortened to varying degrees before severely compromising targeting activity. Surprisingly, shortening some spacers yielded enhanced targeting activity, which was linked to folding of the transcribed array prior to processing. Overall, shortened CRISPR-Cas9 arrays can facilitate multiplexed editing and gene regulation from a smaller DNA footprint across many bacterial applications of CRISPR technologies.

description: We present an improved measurement of CP-violating asymmetries in B0 -> pi+ pi- decays based on a 78 fb^-1 data sample collected at the Y(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. We reconstruct one neutral B meson as a B0 -> pi+ pi- CP eigenstate and identify the flavor of the accompanying B meson from inclusive properties of its decay products. We apply an unbinned maximum likelihood fit to the distribution of the time intervals between the two B meson decay points. The fit yields the CP-violating asymmetry amplitudes Apipi = +0.77+/-0.27(stat)+/-0.08(syst) and Spipi = -1.23+/-0.41(stat)+0.08/-0.07(syst), where the statistical uncertainties are determined from Monte Carlo pseudo-experiments. We obtain confidence intervals for CP-violating asymmetry parameters Apipi and Spipi based on a frequentist approach. We rule out the CP-conserving case, Apipi=Spipi=0, at the 99.93% confidence level. We discuss how these results constrain the value of the CKM angle phi2.

description: We review our present understanding of heterotic compactifications on non-Kahler complex manifolds with torsion. Most of these manifolds can be obtained by duality chasing a consistent F-theory compactification in the presence of fluxes. We show that the duality map generically leads to non-Kahler spaces on the heterotic side, although under some special conditions we recover Kahler compactifications. The dynamics of the heterotic theory is governed by a new superpotential and minimizing this superpotential reproduces all the torsional constraints. This superpotential also fixes most of the moduli, including the radial modulus. We discuss some new connections between Kahler and non-Kahler compactifications, including some phenomenological aspects of the latter compactifications.

description: Two topics dominate discussions of public elementary and secondary education. The first is declining enrollments and the second is fiscal problems, especially those problems associated with such catch words as equity, taxpayer revolt, and tax reform. In this paper, we analyze the relationship between these two topics by examining enrollment change and fiscal characteristics in 504 Pennsylvania school districts. Our purpose is to provide a descriptive base for further research on the fiscal problems raised by changing school enrollments.

TURFs incentivize local stewardship but may be plagued by spatial externalities when the TURF size is insufficient to capture all dispersal. Within a numerical model parameterized to a California marine species, we explore the economic and ecological effects of imposing MPAs on a TURF-regulated fishery. Whether MPAs can enhance or diminish profits (or fish abundance) hinges critically on the level of coordination already occurring between TURF owners. If coordination is complete, private MPAs may already emerge in some TURFs; implementing additional MPAs reduces profits. However, to the extent that coordination is incomplete, strategically sited MPAs may be an effective complement to spatial property rights-based fisheries, increasing both fishery profits and abundance.

description: We overview the roles of production structure models in measuring fisheries’ productive performance to provide policy-relevant guidance for fishery managers and analysts. In particular, we summarize the literature on the representation and estimation of production structure models to construct productive performance measures for fisheries, with a focus on parametric empirical applications and on the management implications of these kinds of measures.

description: Using Koopman's approach to classical dynamical systems we show that the classical damping may be interpreted as appearance of resonant states of the corresponding Koopman's operator. It turns out that simple classical damped systems give rise to discrete complex spectra. Therefore, the corresponding generalized eigenvectors may be interpreted as classical resonant states.

description: Against the background of providing learning opportunities for meaningful mathematics for all students, the presented Design Research study had the goal of investigating how to support students facing language barriers while learning mathematics in phases of unmoderated group work. For this purpose, learning meaningful mathematics and demanding discourse practices are connected with quality interaction characteristics identified in research on productive group work. This theoretical consideration was implemented in a learning arrangement on similarity by means of four design principles for enhancing language in group work on meaningful mathematics. The empirical insights show to what extent the intended demanding discourse practices and quality interaction characteristics can be identified in different steps of knowledge construction, and to what extent they are supported by the design element ‘role cards’. Instead of calling for less unmoderated group work for students facing language barriers, the results of the study suggest that more research is needed to design scaffolds matching students’ needs, aside from whole-class discussions.

description: Young stars are mostly found in dense stellar environments, and even our own Solar system may have formed in a star cluster. Here, we numerically explore the evolution of planetary systems similar to our own Solar system in star clusters. We investigate the evolution of planetary systems in star clusters. Most stellar encounters are tidal, hyperbolic, and adiabatic. A small fraction of the planetary systems escape from the star cluster within 50 Myr; those with low escape speeds often remain intact during and after the escape process. While most planetary systems inside the star cluster remain intact, a subset is strongly perturbed during the first 50 Myr. Over the course of time, 0.3 % - 5.3 % of the planets escape, sometimes up to tens of millions of years after a stellar encounter occurred. Survival rates are highest for Jupiter, while Uranus and Neptune have the highest escape rates. Unless directly affected by a stellar encounter itself, Jupiter frequently serves as a barrier that protects the terrestrial planets from perturbations in the outer planetary system. In low-density environments, Jupiter provides protection from perturbations in the outer planetary system, while in high-density environments, direct perturbations of Jupiter by neighbouring stars is disruptive to habitable-zone planets. The diversity amongst planetary systems that is present in the star clusters at 50 Myr, and amongst the escaping planetary systems, is high, which contributes to explaining the high diversity of observed exoplanet systems in star clusters and in the Galactic field

description: Purpose: A cancer diagnosis can have a substantial impact on one’s mental health. The present study investigated the prevalence and predictors of psychiatric comorbidities in cancer patients at the time of their discharge from the hospital. Methods: Psychiatric comorbidities were assessed shortly before hospital discharge and half a year after hospitalization using a structured clinical interview (SCID), based on the diagnostic and statistical manual of mental disorders (DSM-IV). Frequencies at both time points were estimated using percentages and corresponding 95% confidence intervals. Predictors of mental disorders were identified using binary logistic regression models. Results: At time of hospital discharge, 39 out of 334 patients (12%) were diagnosed with a psychiatric comorbidity, and 15 (7%) were diagnosed half a year later. Among the diagnoses, adjustment disorders (3%) were most frequent at the time of hospital release, while major depression (3%) was the most frequent 6 months later. Having a mental disorder was associated with unemployment (odds ratio (OR) 3.4, confidence interval (CI) 1.1–10.9, p = 0.04). There was no evidence that school education (OR 2.0, CI 0.4–9.0, p = 0.38), higher education (OR 0.7, CI 0.2–2.4, p = 0.60), income (OR 1.0, CI 1.0–1.0, p = 0.06), tumor stage (OR 1.1, CI 0.4–3.2, p = 0.85), type of disease (OR 0.6, CI 0.2–2.1, p = 0.47), pain (OR 1.0, CI 1.0–1.0, p = 0.15), fatigue (OR 1.0, CI 1.0–1.0, p = 0.77), or physical functioning (OR 1.0, CI 1.0–1.0, p = 0.54) were related to the presence of a psychiatric comorbidity. Conclusions: Unemployment was associated with at least a threefold increased risk of mental disorder, which highlights the need for special attention to be given to this subgroup of cancer patients.

description: This study examines the impact of flood-hazard zone location on residential property prices. The study utilises data from over 2000 private residential property sales occurred during 2006 in North Shore City, New Zealand. A spatial autoregressive hedonic model is developed to provide efficient estimates of the marginal effect of flood prone risks on property prices. Results suggest that the sale price of a residential property within a flood prone area is lower than an equivalent property outside the flood prone area. The flood plain location discount is reduced by the release of public information regarding flood risk.

description: При проектуванні пристроїв з еластомірними елементами конструкцій в якості демпферів одним з надважливих завдань є визначення їх напружено-деформованого стану в умовах експлуатаційних навантажень, а також прогнозування їх довговічності на основі різних критеріїв руйнування.Такі конструкції, як правило, працюють в умовах циклічного деформування, при цьому проявляється ефект розсіювання енергії деформації, що призводить до дисипативного розігріву в’язкопружних еластомерних елементів. Розглянуто процеси деформування та дисипативного розігріву гумових вібро- та сейсмоізоляторів. Для розв’язання задачі термомеханіки конструкцій з початковими напруженнями використовується інкрементальна теорія деформованого тіла. Для розв’язання задачі деформування слабостисливих еластомерних елементів використовується моментна схема скінченних елементів з потрійною апроксимацією переміщень, деформацій та функції зміни об’єму. Для розв’язання зв’язаної задачі термопружності використовується метод послідовних наближень.

description: Perceptions of a salinity ‘crisis’ in Australia around 2000 resulted in the establishment of a major national program that aimed to prevent, stabilize, and reverse trends in salinity. The National Action Plan for Salinity and Water Quality allocated A$1.4 billion of public funds to 1700 projects over 7 years. Here, we assess the performance of the program in relation to 12 features that we propose as being essential for programs that aim to address complex environmental problems. The features include use of technical information to guide investment prioritization, use of socio-economic information, effective integration of information for prioritization, selection of appropriate targets, choice of appropriate policy mechanisms, and provision of incentives and support to environmental managers to pursue environmental outcomes cost effectively. Our assessment reinforces findings from a number of public reviews that found serious weaknesses in the program. Overall, with a few exceptions, projects under the National Action Plan generated few worthwhile salinity mitigation benefits and will have little enduring benefit. This was readily foreseeable given attention to the scientific and economic knowledge of salinity available at the time the program was developed.

description: Значна вартість натурних експериментів, а в деяких випадках неможливість їх проведення через складність моделювання реальних процесів визначили широке розповсюдження математичних, аналітичних і чисельних методів розрахунків на міцність, особливе місце серед яких займає метод скінченних елементів (МСЕ). В рамках напіваналітичного варіанта МСЕ розглянута бібліотека скінченних елементів для апроксимації просторових неоднорідних тіл обертання і призматичних тіл неканонічної форми в процесах їх нестаціонарного деформування під дією динамічного навантаження з урахуванням великих пластичних деформацій. Представлені базові кільцевий та призматичний скінченні елементи з різними видами граничних умов, на основі яких побудовані спеціальні СЕ для моделювання фізично нелінійної роботи матеріалу та змінних зон контактної взаємодії. Наведені тестові приклади демонструютьвисоку достовірність та ефективність запропонованих рішень.
