description: In this paper, we construct $\bar{D}^{(*)}_{s}D^{(*)}$-molecule-type interpolating currents $J_{(\pm)μ}(x)$ with $J^{P}=1^{+}$, calculate the corresponding mass and magnetic moment using the QCD sum rule method and its extension in the weak electromagnetic field, and study the processes of $Z_{(\pm)cs}$ to $η_{c}K^{*}$, $J/ψK$, $\bar{D}D^{*}_{s}$, and $\bar{D}^{*}D_{s}$ via three-point sum rules. The numerical values are $m_{Z_{(\pm)cs}}=3.99^{+0.17}_{-0.14}~\mbox{GeV}$, and $λ_{Z_{(\pm)cs}}=2.07^{+0.28}_{-0.16}\times10^{-2}~\mbox{GeV}^{5}$, $μ_{Z_{(\pm)cs}}=0.18^{+0.16}_{-0.09}~μ_{N}$ with $μ_{N}$ the nucleon magneton, $Γ_{Z_{(+)cs}}=17.47^{+12.70}_{-8.08}$, and $Γ_{Z_{(-)cs}}=13.86^{+10.37}_{-6.51}$. The masses are in agreement with the recently measured value of $Z_{cs}(3985)$ by the BESIII Collaboration, $m^{exp}_{Z_{cs}}=(3982.5^{+1.8}_{-2.6}\pm2.1)~\mbox{MeV}$. The widths are compatible with the experimental value, $Γ^{exp}_{Z_{cs}}=(12.8^{+5.3}_{-4.4}\pm3.0)~\mbox{MeV}$. The magnetic moment and the various decay modes can help us to determine the inner structure of $Z_{cs}(3985)$ when being confronted with experimental data in the future.

description: When used in conjunction with surface water for irrigation, groundwater serves two roles: to increase water supply; and to mitigate fluctuations in the supply of water. The later is the buffer role. This paper identifies and evaluates the economic benefit associated with the buffer role of ground water. Implications for the development of groundwater resources are investigated. An estimate is given of the buffer benefit to wheat growers of the fossil water aquifer underlying the Israeli Negev. It is found that, under the prevailing variability in the supply of surface water, this benefit may well exceed the groundwater benefit associated with the increase in water supply.
Cooling Evolution of Hybrid Stars

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The cooling of compact isolated objects for different values of the gravitational mass has been simulated for two alternative assumptions. One is that the interior of the star is purely hadronic and second that the star can have a rather large quark core. It has been shown that within a nonlocal chiral quark model the critical density for a phase transition to color superconducting quark matter under neutron star conditions can be low enough for these phases to occur in compact star configurations with masses below 1.3 M_sun. For a realistic choice of parameters the equation of state (EoS) allows for 2SC quark matter with a large quark gap ~ 100 MeV for u and d quarks of two colors that coexists with normal quark matter within a mixed phase in the hybrid star interior. We argue that, if in the hadronic phase the neutron pairing gap in 3P_2 channel is larger than few keV and the phases with unpaired quarks are allowed, the corresponding hybrid stars would cool too fast. Even in the case of the essentially suppressed 3P_2 neutron gap if free quarks occur for M < 1.3 M_sun, as it follows from our EoS, one could not appropriately describe the neutron star cooling data existing by today. It is suggested to discuss a "2SC+X" phase, as a possibility to have all quarks paired in two-flavor quark matter under neutron star constraints, where the X-gap is of the order of 10 keV - 1 MeV. Density independent gaps do not allow to fit the cooling data. Only the presence of an X-gap that decreases with increase of the density could allow to appropriately fit the data in a similar compact star mass interval to that following from a purely hadronic model.

Sex differences and consequences of peripheral blood leukocytosis after spinal cord injury in Fischer 344 rats
Creators: name: Ayala, Carlos
Publisher: name: No Publisher Supplied
Year: 2021

description: Four times as many men as women have chronic spinal cord injury (SCI), suggesting that women have less severe SCI than men. The mechanism of this large sex gap is not known. SCI changes peripheral blood leukocyte counts, causing acute neutrophilia chronic lymphopenia after injury. Neutrophils infiltrate the injured spinal cord. We compared peripheral blood leukocyte responses in male and female Fischer F344 rats. Males had greater blood neutrophilia than females during the first days after SCI. We also measured myeloperoxidase (MPO) by Western Blot injured spinal cords. Surprisingly, MPO did not differ between male and female rats, despite greater peripheral neutrophilia in males. We assessed effects of blood leukocyte responses on locomotor recovery. We treated male and female rats with the chemotherapeutic agent cyclophosphamide (CYP) 2 days before SCI to reduce acute blood neutrophilia and evaluated locomotor recovery and neuronal and myelin sparing in the spinal cords at 6 weeks after injury. CYP prevented increases in blood neutrophil counts after SCI. However, blood neutrophil counts did not correlate with tissue damage or behavioral recovery. Male rats recovered walking earlier than female rats regardless of blood neutrophilia. Differences in recovery were transient and not significant 3 to 6 weeks afterSCI. Quantitative analyses of the rat spinal cords showed that standardized contusion injury caused similar tissue loss, myelin sparing, and neuron survival in both sexes. However, male spinal cords were bigger in age-matched 100-day-old F344 rats. Preventing acute blood neutrophil responses did not change walking recovery or tissue damage in either sex. These findings argue strongly against the hypothesis that acute neutrophilia is responsible for sex differences in recovery after SCI. We conclude that acute blood leukocytosis do not affect recovery or tissue damage after spinal cord injury in F344 rats.

description: The Jordan-Wigner transformation is applied to study the ground state properties and dimerization transition in the $J_1-J_2$ $XXZ$ chain. We consider different solutions of the mean-field approximation for the transformed Hamiltonian. Ground state energy and the static structure factor are compared with complementary exact diagonalization and good agreement is found near the limit of the Majumdar-Ghosh model. Furthermore, the ground state phase diagram is discussed within the mean-field theory. In particular, we show that an incommensurate ground state is absent for large $J_2$ in a fully self-consistent mean-field analysis.

description: The ordering of particles in the drying process of a colloidal suspension is crucial in determining the properties of the resulting film. For example, microscopic inhomogeneities can lead to the formation of cracks and defects that can deteriorate the quality of the film considerably. This type of problem is inherently multiscale and here we study it numerically, using our recently developed method for the simulation of soft polymeric capsules in multicomponent fluids. We focus on the effect of the particle softness on the film microstructure during the drying phase and how it relates to the formation of defects. We quantify the order of the particles by measuring both the Voronoi entropy and the isotropic order parameter. Surprisingly, both observables exhibit a non-monotonic behaviour when the softness of the particles is increased. We further investigate the correlation between the interparticle interaction and the change in the microstructure during the evaporation phase. We observe that the rigid particles form chain-like structures that tend to scatter into small clusters when the particle softness is increased.

description: We develop a theory of the excitonic phase recently proposed as the zero-field insulating state observed near charge neutrality in monolayer WTe$_2$. Using a Hartree-Fock approximation, we numerically identify two distinct gapped excitonic phases: a spin density wave state for weak non-zero interaction strength and spin spiral order at stronger interactions, separated by a narrow window of non-excitonic quantum spin Hall insulator. We introduce a simplified model capturing key features of the WTe$_2$ band structure, in which these phases appear as distinct valley ferromagnetic orders. We link the competition between the excitonic phases to the orbital structure of electronic wavefunctions at the Fermi surface and hence its proximity to the underlying gapped Dirac point in WTe$_2$. We briefly discuss collective modes of the two excitonic states, and comment on implications for experiments.

Timing Cache Accesses to Eliminate Side Channels in Shared Software
Creators: name: Ojha, Divya

Publisher: name: arXiv
Year: 2020
Subjects: subject: Cryptography and Security (cs.CR)
subject: FOS: Computer and information sciences

description: Timing side channels have been used to extract cryptographic keys and sensitive documents, even from trusted enclaves. In this paper, we focus on cache side channels created by access to shared code or data in the memory hierarchy. This vulnerability is exploited by several known attacks, e.g, evict+reload for recovering an RSA key and Spectre variants for data leaked due to speculative accesses. The key insight in this paper is the importance of the first access to the shared data after a victim brings the data into the cache. To eliminate the timing side channel, we ensure that the first access by a process to any cache line loaded by another process results in a miss. We accomplish this goal by using a combination of timestamps and a novel hardware design to allow efficient parallel comparisons of the timestamps. The solution works at all the cache levels and defends against an attacker process running on another core, same core, or another hyperthread. Our design retains the benefits of a shared cache: allowing processes to utilize the entire cache for their execution and retaining a single copy of shared code and data (data deduplication). Our implementation in the GEM5 simulator demonstrates that the system is able to defend against RSA key extraction. We evaluate performance using SPECCPU2006 and observe overhead due to first access delay to be 2.17%. The overhead due to the security context bookkeeping is of the order of 0.3%.

description: This paper addresses itself to three aspects of world food and fiber needs and the protection of the ecosystem. The first is to distinguish between food and fiber needs of the world on the one hand, and the production of food and fiber in developing countries as part of a long-term process of economic development on the other. The second area of attention is the role of science and technology in the process of agricultural modernization and development. Finally, we will look at a class of problems dealing with socially costly externalities associated with agricultural development and the use of new technologies.

description: Several observables of unbound nucleons which are to some extent sensitive to the medium modifications of nucleon-nucleon elastic cross sections in neutron-rich intermediate energy heavy ion collisions are investigated. The splitting effect of neutron and proton effective masses on cross sections is discussed. It is found that the transverse flow as a function of rapidity, the $Q_{zz}$ as a function of momentum, and the ratio of halfwidths of the transverse to that of longitudinal rapidity distribution $R_{t/l}$ are very sensitive to the medium modifications of the cross sections. The transverse momentum distribution of correlation functions of two-nucleons does not yield information on the in-medium cross section.

Speak to me: using social marketing to enhance involvement : among 18-35 year olds in the public participation process
Creators: name: Carvalho, Nadia V.
Publisher: name: University of British Columbia
Year: 2009

description: Public participation in the development of the Official Community Plan has become a commonplace concept. The techniques that we use have evolved over the last 25 years. Planners need to further develop these techniques to enhance their effectiveness. It is important that planners are effective at educating and engaging the public in the search for creative solutions for some of the challenges facing communities today. It is especially important that these techniques speak to those between the ages of 18-34 because they are the ones who will be buying homes and forming families, actions, when aggregated, have the power to shape and reshape our cities. Both the health and environmental movements have successfully used social marketing for years. Social marketing attempts to influence behaviour for the common good. Social marketing has proven to be successful at changing behaviour and this can be partially attributed to its customer orientation. The primary tenet of social marketing is to understand and build a relationships with customers on their terms. This thesis argues that it is time for planners to understand and build relationships with residents on their terms using a social marketing framework. Case studies from environmental, health advocacy and political groups detail innovative campaigns which were designed to engage a younger audience and remove any barriers a participant might face when trying to take action. The characteristics that these campaigns share provide interesting lessons for planners wishing to do the same for their public participation strategies.

description: We consider the task of performing quantum state tomography on a $d$-level spin qudit, using only measurements of spin projection onto different quantization axes. After introducing a basis of operators closely related to the spherical harmonics, which obey the rotational symmetries of spin qudits, we map our quantum tomography task onto the classical problem of signal recovery on the sphere. We then provide algorithms with $O(rd^3)$ serial runtime, parallelizable down to $O(rd^2)$, for (i) computing a priori upper bounds on the expected error with which spin projection measurements along $r$ given axes can reconstruct an unknown qudit state, and (ii) estimating a posteriori the statistical error in a reconstructed state. Our algorithms motivate a simple randomized tomography protocol, for which we find that using more measurement axes can yield substantial benefits that plateau after $r\approx3d$.

description: We construct a two-dimensional N=8 supersymmetric quantum mechanics which inherits the most interesting properties of N=2, $d=4$ supersymmetric Yang-Mills theory. After dimensional reduction to one dimension in terms of field-strength, we show that only complex scalar fields from the $N=2, d=4$ vector multiplet become physical bosons in $d=1$. The rest of the bosonic components are reduced to auxiliary fields, thus giving rise to the {\bf (2, 8, 6)} supermultiplet in $d=1$. We construct the most general superfields action for this supermultiplet and demonstrate that it possesses duality symmetry extended to the fermionic sector of theory. We also explicitly present the Dirac brackets for the canonical variables and construct the supercharges and Hamiltonian which form a N=8 super Poincarè algebra with central charges. Finally, we discuss the duality transformations which relate the {\bf (2, 8, 6)} supermultiplet with the {\bf (4, 8, 4)} one.

description: An established strategy for material modeling is provided by energy-based principles such that evolution equations in terms of ordinary differential equations can be derived. However, there exist a variety of material models that also need to take into account non-local effects to capture microstructure evolution. In this case, the evolution of microstructure is described by a partial differential equation. In this contribution, we present how Hamilton's principle provides a physically sound strategy for the derivation of transient field equations for all state variables. Therefore, we begin with a demonstration how Hamilton's principle generalizes the principle of stationary action for rigid bodies. Furthermore, we show that the basic idea behind Hamilton's principle is not restricted to isothermal mechanical processes. In contrast, we propose an extended Hamilton principle which is applicable to coupled problems and dissipative microstructure evolution. As example, we demonstrate how the field equations for all state variables for thermo-mechanically coupled problems, i.e. displacements, temperature, and internal variables, result from the stationarity of the extended Hamilton functional. The relation to other principles, as principle of virtual work and Onsager's principle, are given. Finally, exemplary material models demonstrate how to use the extended Hamilton principle for thermo-mechanically coupled rate-dependent, rate-independent, and gradient-enhanced materials.

description: The efficient preparation of input distributions is an important problem in obtaining quantum advantage in a wide range of domains. We propose a novel quantum algorithm for the efficient preparation of arbitrary normal distributions in quantum registers. To the best of our knowledge, our work is the first to leverage the power of Mid-Circuit Measurement and Reuse (MCMR), in a way that is broadly applicable to a range of state-preparation problems. Specifically, our algorithm employs a repeat-until-success scheme, and only requires a constant-bounded number of repetitions in expectation. In the experiments presented, the use of MCMR enables up to a 862.6x reduction in required qubits. Furthermore, the algorithm is provably resistant to both phase-flip and bit-flip errors, leading to a first-of-its-kind empirical demonstration on real quantum hardware, the MCMR-enabled Honeywell System Models H0 and H1-2.

description: We calculate Ext^*_{SL_2(k)}(Δ(λ), Δ(μ)), Ext^*_{SL_2(k)}(L(λ), Δ(μ)), Ext^*_{SL_2(k)}(Δ(λ), L(μ)), and Ext^*_{SL_2(k)}(L(λ), L(μ)), where Δ(λ) is the Weyl module of highest weight λ, L(λ) is the simple SL_2(k)-module of highest weight λand our field k is algebraically closed of positive characteristic. We also get analogous results for the Dipper-Donkin quantisation. To do thus we construct the Lyndon-Hochschild-Serre spectral sequence in a new way, and find a new condition for the E_2 page of any spectral sequence to be the same as the E_\infty page.

description: Studies of active matter, from molecular assemblies to animal groups, have revealed two broad classes of behavior: a tendency to align yields orientational order and collective motion, whereas particle repulsion leads to self-trapping and motility-induced phase separation. Here, we report a third class of behavior: orientational interactions that produce active phase separation. Combining theory and experiments on self-propelled Janus colloids, we show that stronger repulsion on the rear than on the front of these particles produces non-reciprocal torques that reorient particle motion toward high-density regions. Particles thus self-propel toward crowded areas, which leads to phase separation. Clusters remain fluid and exhibit fast particle turnover, in contrast to the jammed clusters that typically arise from self-trapping, and interfaces are sufficiently wide that they span entire clusters. Overall, our work identifies a torque-based mechanism for phase separation in active fluids, and our theory predicts that these orientational interactions yield coexisting phases that lack internal orientational order.

description: We propose a measure of interaction-induced ground state entanglement in many-fermion systems that is experimentally accessible. It is formulated in terms of cross-correlations of currents through resonant fermion levels weakly coupled to the probed system. The proposed entanglement measure vanishes in the absence of many-body interactions and it is related to measures of occupation number entanglement. We evaluate it for two examples of interacting electronic nanostructures.

description: Assuming a vacancy-mediated diffusion, a continuum model for electromigration-driven transport of an embedded atom cluster across a surface terrace of a phase-separating A$_x$B$_{1-x}$ surface alloy, such as fcc AgPt(111), is presented. Computations show that the electron wind carries the cluster over hundreds of lattice spacings and in the set direction, while the cluster grows and its purity improves during the drift. Impacts of the current density, the diffusion anisotropy, the magnitude and sign of the ratio of the effective charges $q_A/q_B$, and the jump frequencies ratio $Γ_A/Γ_B$ on the cluster's drift speed, drift direction, purity and shape are demonstrated.

description: We consider multipartite states of qubits and prove that their bipartite quantum entanglement, as quantified by the concurrence, satisfies a monogamy inequality conjectured by Coffman, Kundu, and Wootters.

description: Defects in superfluid 3He, high-Tc superconductors, QCD colour superfluids and cosmic vortons can possess (anti)ferromagnetic cores, and their generalisations. In each case there is a second order parameter whose value is zero in the bulk which does not vanish in the core. We examine the production of defects in the simplest 1+1 dimensional scalar theory in which a second order parameter can take non-zero values in a defect core. We study in detail the effects of core condensation on the defect production mechanism.

description: In this paper, we study the local properties of the moduli space of a polarized Calabi-Yau manifold. Let $U$ be a neighborhood of the moduli space. Then we know the universal covering space $V$ of $U$ is a smooth manifold. Suppose $D$ is the classifying space of a polarized Calabi-Yau manifold with the automorphism group $G$. Let $D_1$ be the symmetric space associated with $G$. Then we proved that the map from $V$ to $D_1$ induced by the period map is a pluriharmonic map. We also give a Kahler metric on $V$, which is called the Hodge metric. We proved that the Ricci curvature of the Hodge metric is negative away from zero. We also proved the non-existence of the Kähler metric on the classifying space of a Calabi-Yau threefold which is invariant under a cocompact lattice of $G$.

description: Many language pairs are low resource, meaning the amount and/or quality of available parallel data is not sufficient to train a neural machine translation (NMT) model which can reach an acceptable standard of accuracy. Many works have explored using the readily available monolingual data in either or both of the languages to improve the standard of translation models in low, and even high, resource languages. One of the most successful of such works is the back-translation that utilizes the translations of the target language monolingual data to increase the amount of the training data. The quality of the backward model which is trained on the available parallel data has been shown to determine the performance of the back-translation approach. Despite this, only the forward model is improved on the monolingual target data in standard back-translation. A previous study proposed an iterative back-translation approach for improving both models over several iterations. But unlike in the traditional back-translation, it relied on both the target and source monolingual data. This work, therefore, proposes a novel approach that enables both the backward and forward models to benefit from the monolingual target data through a hybrid of self-learning and back-translation respectively. Experimental results have shown the superiority of the proposed approach over the traditional back-translation method on English-German low resource neural machine translation. We also proposed an iterative self-learning approach that outperforms the iterative back-translation while also relying only on the monolingual target data and require the training of less models.

description: Dopo l'elezione a imperatore del Sacro Romano Impero (1530), Carlo V d’Asburgo (1500-1558) ottiene il controllo sul più vasto dominio della storia dell'umanità. In che modo la coesistenza di tradizioni, lingue e geografie diverse si riflette sulla cultura architettonica? Utilizzando l’Impero di Carlo V come osservatorio, questo volume interroga le diverse scale del progetto, confrontandosi con i più recenti orientamenti critici. Facendo dialogare le questioni storiche con quelle storiografiche, i dieci saggi qui raccolti, dedicati al Vecchio e al Nuovo Mondo, propongono una riflessione trasversale sull’arte del costruire, apportando contributi originali e illustrando nuovi approcci alla ricerca.
Established and emerging personality constructs in behavioral cardiology : associations with resting blood pressure and cardiovascular responses to acute stress
Creators: name: Habra, Martine E.
Publisher: name: University of British Columbia
Year: 2009

description: Studies have revealed associations between established psychosocial factors and cardiovascular health, but the magnitude of effects remains small, and findings are fraught with inconsistencies. Recently, several putative psychological risk factors for cardiovascular disease, namely social support seeking, sociotropy, and Type-D personality, defensiveness and sex roles, have been proposed to further elucidate the relationship between personality and disease. The purpose of the present study was to examine how such emerging constructs relate to laboratory indices of cardiovascular health compared to more established psychosocial risk factors, i.e., hostility and social support. 173 undergraduates (87 female, 86 male) completed a stress protocol involving a mental arithmetic task (serial subtractions of seven) while receiving scripted harassing comments. Blood pressure and heart rate were measured both prior to and during the stressful task. The relationships between personality and both resting and reactivity levels were examined. Reactivity was defined as the amount of change between resting blood pressure and heart rate levels and levels reached during the task. Contrary to prediction, hostility was associated with lower resting blood pressure, while social support was unrelated to cardiovascular responses. Emerging personality constructs demonstrated consistent associations with physiology. Masculinity was associated with lower resting heart rate [β = -.26, p < .01]. Support seeking was associated with less SBP reactivity to the task (r = -.15, g = .05). Sociotropy was related to dampened reactivity to stress [β = -.21, p < .05 for DBP; β = -.22, p < .05 for HR]. Males who reported greater social inhibition, a dimension of the Type-D personality, showed greater reactivity to the lab stressor [β = .41, p < .01 for SBP; β = .31, p < .05 for DBP]. Impression management was also associated with resting blood pressure, but gender differences in the pattern of associations were noted. Thus, the present results confirm the need to move away from global personality dimensions in order to explain better how personality can exert beneficial or deleterious effects on health. However, the direction o f results was not always consistent with our predictions, indicating that these specific personality constructs would benefit from further refinement.

description: Nitrate concentration in ground water is a major problem in specific agricultural areas. Using regression and neural networks, this study models nitrate concentration in ground water as a function of iron concentration in ground water, season and distance of the well from a poultry house. Results from both techniques are comparable and show that the distance of the well from a poultry house has a significant effect on nitrate concentration in groundwater.

description: It is becoming increasingly clear that an important task for wireless networks is to minimize the age of information (AoI), i.e., the timeliness of information delivery. While mainstream approaches generally rely on the real-time observation of user AoI and channel state, there has been little attention to solve the problem in a complete (or partial) absence of such knowledge. In this article, we present a novel study to address the optimal blind radio resource scheduling problem in orthogonal frequency division multiplexing access (OFDMA) systems towards minimizing long-term average AoI, which is proven to be the composition of time-domain-fair clustered round-robin and frequency-domain-fair intra-cluster sub-carrier assignment. Heuristic solutions that are near-optimal as shown by simulation results are also proposed to effectively improve the performance upon presence of various degrees of extra knowledge, e.g., channel state and AoI.
