description: Dipolar condensates have recently been coaxed to form the long-sought supersolid phase. While one-dimensional supersolids may be prepared by triggering a roton instability, we find that such a procedure in two dimensions (2D) leads to a loss of both global phase coherence and crystalline order. Unlike in 1D, the 2D roton modes have little in common with the supersolid configuration. We develop a finite-temperature stochastic Gross-Pitaevskii theory that includes beyond-mean-field effects to explore the formation process in 2D and find that evaporative cooling directly into the supersolid phase--hence bypassing the first-order roton instability--can produce a robust supersolid in a circular trap. Importantly, the resulting supersolid is stable at the final nonzero temperature. We then experimentally produce a 2D supersolid in a near-circular trap through such an evaporative procedure. Our work provides insight into the process of supersolid formation in 2D and defines a realistic path to the formation of large two-dimensional supersolid arrays.

description: We study the dynamics of membrane vesicle motor transport into dendritic spines, which are bulbous intracellular compartments in neurons that play a key role in transmitting signals between neurons. We consider the stochastic analog of the vesicle transport model in [Park and Fai, The Dynamics of Vesicles Driven Into Closed Constrictions by Molecular Motors. Bull. Math. Biol. 82, 141 (2020)]. The stochastic version, which may be considered as an agent-based model, relies mostly on the action of individual myosin motors to produce vesicle motion. To aid in our analysis, we coarse-grain this agent-based model using a master equation combined with a partial differential equation describing the probability of local motor positions. We confirm through convergence studies that the coarse-graining captures the essential features of bistability in velocity (observed in experiments) and waiting-time distributions to switch between steady-state velocities. Interestingly, these results allow us to reformulate the translocation problem in terms of the mean first passage time for a run-and-tumble particle moving on a finite domain with absorbing boundaries at the two ends. We conclude by presenting numerical and analytical calculations of vesicle translocation.

Quelle autonomie financière des collectivités territoriales au Maroc ?

description: Le long chemin qu’a entrepris le Maroc en matière de décentralisation, couronné par la mise en œuvre de la régionalisation avancée et la promulgation, en 2015, des lois organiques régissant les collectivités territoriales, a permis à ces dernières de devenir un acteur capital sur la scène de développement socioéconomique. Ainsi, le choix de ce mode d’organisation territoriale, ne doit pas se limiter à l’octroi d’un certain nombre de prérogatives, ni à simple transfert de responsabilités, de ressources et de moyens, mais plutôt, d’assurer aux autorités infranationales la reconnaissance d’une « liberté d’administration » et d’une large « autonomie financière ». Cela requiert la mise en place d’un système financier valable localement, permettant de mobiliser et de débourser des ressources propres pour financer les projets de développement territoriaux. La présente recherche vise à mesurer l’autonomie financière de quatre Communes marocaines (Azrou, Khénifra, Sidi Kacem et Tinghir) par l’élaboration d’un indicateur d’autonomie financière (IAF) sur la base des données financières et comptables desdites Communes. Les résultats obtenus montrent que cet indicateur diffère d’une Commune à une autre (varie entre 33,33% et 58,33%) suivant la structure de leurs recettes, de leur capacité à générer des revenus propres, de l’efficacité de gestion budgétaire, ainsi que du cadre législatif.

description: Fine-grained Smart Meters (SMs) data recording and communication has enabled several features of Smart Grids (SGs) such as power quality monitoring, load forecasting, fault detection, and so on. In addition, it has benefited the users by giving them more control over their electricity consumption. However, it is well-known that it also discloses sensitive information about the users, i.e., an attacker can infer users' private information by analyzing the SMs data. In this study, we propose a privacy-preserving approach based on non-uniform down-sampling of SMs data. We formulate this as the problem of learning a sparse representation of SMs data with minimum information leakage and maximum utility. The architecture is composed of a releaser, which is a recurrent neural network (RNN), that is trained to generate the sparse representation by masking the SMs data, and an utility and adversary networks (also RNNs), which help the releaser to minimize the leakage of information about the private attribute, while keeping the reconstruction error of the SMs data minimum (i.e., maximum utility). The performance of the proposed technique is assessed based on actual SMs data and compared with uniform down-sampling, random (non-uniform) down-sampling, as well as the state-of-the-art in privacy-preserving methods using a data manipulation approach. It is shown that our method performs better in terms of the privacy-utility trade-off while releasing much less data, thus also being more efficient.

description: Community-supported, values-driven digital preservation services operate in a landscape where the increasing economic, labor, and climate challenges are too big for any one organization to tackle alone.

In the context of these challenges, the Educopia Institute—in partnership with APTrust, Chronopolis, CLOCKSS, lyrasis, the MetaArchive Cooperative, and the Texas Digital Library (six members of the Digital Preservation Services Collaborative)—sought funding from the Institute of Library and Museum Services (IMLS) to reaffirm the need for—and to establish a shared vision for—the sustained viability of values-driven, community-supported approaches to distributed digital preservation (DDP).

As the project advanced we were reminded that, as technical service providers, we too are embedded in a broader cultural context that is unconsciously biased towards technocentric solutions, or solutions that foreground technological infrastructures and background social infrastructures. Acknowledging that there are technical and non-technical requirements across the information management continuum, our shared service model vision aims to offer two additional services at discrete moments in the institutional decision-making process: "advocacy-as-a-service," best deployed at the institutional preservation strategy-forming moment; and "readiness-as-a-service," assisting stewardship organizations that have recently formed their preservation strategy to identify the content, preservation needs, budget realities, etc., as they begin to research the digital preservation services landscape.

Beyond individual organizations, readiness-as- a-service is also a call for collective strategy among values-driven, community-supported bit- level6 service providers to anticipate and be prepared to respond to change (and to shocks) in a nimble, coordinated, collaborative way.

We think this vision offers an exciting and viable path forward for values-driven, community- supported service providers, and we hope this vision will attract additional service providers and grow our coalition of support.

description: Active matter, responsive ("smart") materials and materials under time-dependent load are systems out of thermal equilibrium. To construct coarse-grained models for such systems, one needs to integrate out a distribution of microstates that evolves in time. This is a challenging task. As a preparation to the topic, we recall equilibrium coarse-graining methods, both theoretical and numerical, such as projection operator formalisms, united atom simulations, numerical reconstruction of memory and Markov State Modelling. Then we review recent developments in theoretical approaches to the non-equilibrium coarse-graining problem, in particular, time-dependent projection operator formalisms, dynamic density functional theory and power functional theory, as well as numerical schemes to contruct explicitly time-dependent memory kernels.

description: We quantify the consequences of a private key leakage and private randomness generated during quantum key distribution. We provide simple lower bounds on the one-way distillable key after the leakage has been detected. We also show that the distributed private randomness does not drop by more than twice the number of qubits of the traced-out system. We further focus on irreducible private states, showing that their two-way distillable key is non-lockable. We then strengthen this result by referring to the idea of recovery maps. We further consider the action of special case of side-channels on some of the private states. Finally, we connect the topic of (non)markovian dynamics with that of hacking. In particular, we show that an invertible map is non-CP-divisible if and only if there exists a state whose the key witnessed by a particular privacy witness increases in time. This complements the recent result of J. Kolodyński et al. [Phys. Rev. A 101, 020303(R) (2020)] where the log-negativity was connected with the (non)markovianity of the dynamics.

description: Bosonic quantum error-correcting codes offer a viable direction towards reducing the hardware overhead required for fault-tolerant quantum information processing. A broad class of bosonic codes, namely rotation-symmetric codes, can be characterized by their phase-space rotation symmetry. However, their performance has been examined to date only within an idealistic noise model. Here, we further analyze the error-correction capabilities of rotation-symmetric codes using a teleportation-based error-correction circuit. To this end, we numerically compute the average gate fidelity, including measurement errors into the noise model of the data qubit. Focusing on physical measurement models, we assess the performance of heterodyne and adaptive homodyne detection in comparison to the previously studied canonical phase measurement. This setting allows us to shed light on the role of different currently available measurement schemes when decoding the encoded information. We find that with the currently achievable measurement efficiencies in microwave optics, bosonic rotation codes undergo a substantial decrease in their break-even potential. In addition, we perform a detailed analysis of Gottesman-Kitaev-Preskill (GKP) codes using a similar error-correction circuit that allows us to analyze the effect of realistic measurement models on different codes. In comparison to RSB codes, we find for GKP codes an even greater reduction in performance together with a vulnerability to photon-number dephasing. Our results show that highly efficient measurement protocols constitute a crucial building block towards error-corrected quantum information processing with bosonic continuous-variable systems.

description: Abstract: “Can they do whatever they please. . . Turn settlements into barren land. Dense forests into deserts. Mornings into evenings. Turn fertile into barren. Why shall I not resist!. …. I become my whole self. . . Why shall I not resist”!. This is a section from a poem - ‘Joli No Udhim Kittei’ a Chakma poem written in Bengali script as ‘Rukhe Darabo Na Keno?’ (‘Why shall I not resist!’) by the author \Kabita Chakma in 1992, translated into English. It epitomizes the ongoing violation of human rights that Chakmas (members of one of the Indigenous communities in Bangladesh) experience in the Chittagong Hill Tracts (CHT) where the highest number of Indigenous people in Bangladesh live. In this paper, the first author, a member of the Chakma community and a Lecturer at an Australian university is in conversation with the second author, a Professor at a university in a Bangladeshi university. With reference to Phillipson’s linguicism, and Foucault's notion of governmentality in the era of the Anthropocene, in their conversation, they reflect on the Anthropocene – the forced migration, displacement of Indigenous communities in Bangladesh from their traditional land, extinction of Indigenous languages, disengagement with Indigenous and local languages, and consequently, and the destruction of biodiversity of Chittagong Hill Tracts.
Quantum Monte Carlo simulation of spin-boson models using wormhole updates

description: We present an exact quantum Monte Carlo method for spin systems coupled to dissipative bosonic baths which makes use of nonlocal wormhole updates to simulate the retarded spin-flip interactions originating from an off-diagonal spin-boson coupling. The method is closely related to the stochastic series expansion and extends the scope of the global directed-loop updates to nonlocal moves through a world-line configuration. We test our method for the U(1)-symmetric two-bath spin-boson model, where the off-diagonal components of a spin-$1/2$ particle are coupled to identical independent baths with power-law spectra, and get a precise estimate of the critical coupling between the critical and the localized phase. Our method applies to impurity systems and lattice models in any spatial dimension coupled to bosonic modes with arbitrary spectral distributions.

description: In May 2008 nearly 90,000 people died in the most powerful earthquake in modern Chinese history. Many were students killed in substandard schools, creating a sensitive disaster zone inside a nation whose civil society organizations are beginning to flourish. This paper examines the education earthquake relief program of an international NGO, and the institutional environment the organization worked in. We argue that the restricted environment prevented implementation of high-impact programs in the most deprived places, but that the NGO needed to use the institutional opening created by the earthquake to establish a presence as an agent in China's development.

description: Reasoning on knowledge graph (KG) has been studied for explainable recommendation due to it's ability of providing explicit explanations. However, current KG-based explainable recommendation methods unfortunately ignore the temporal information (such as purchase time, recommend time, etc.), which may result in unsuitable explanations. In this work, we propose a novel Time-aware Path reasoning for Recommendation (TPRec for short) method, which leverages the potential of temporal information to offer better recommendation with plausible explanations. First, we present an efficient time-aware interaction relation extraction component to construct collaborative knowledge graph with time-aware interactions (TCKG for short), and then introduce a novel time-aware path reasoning method for recommendation. We conduct extensive experiments on three real-world datasets. The results demonstrate that the proposed TPRec could successfully employ TCKG to achieve substantial gains and improve the quality of explainable recommendation.

description: We investigate emergent quantum dynamics of the tilted Ising chain in the regime of a weak transverse field. Within the leading order perturbation theory, the Hilbert space is fragmented into exponentially many decoupled sectors. We find that the sector made of isolated magnons is integrable with dynamics being governed by a constrained version of the XXZ spin Hamiltonian. As a consequence, when initiated in this sector, the Ising chain exhibits ballistic transport on unexpectedly long times scales. We quantitatively describe its rich phenomenology employing exact integrable techniques such as Generalized Hydrodynamics. Finally, we initiate studies of integrability-breaking magnon clusters whose leading-order transport is activated by scattering with surrounding isolated magnons.

description: Abstract

The importance of understanding the role of organizational commitment in the educational context and emphasizing the relevance of leadership style factors and job satisfaction in shaping this aspect. This research aims to identify and analyze the influence of leadership style and job satisfaction on the organizational commitment of State Madrasah Aliyah (MAN) teachers in West Sumatra. The research method uses a quantitative approach with path analysis using a decomposition model, involving the population of MAN teachers in West Sumatra who have the status of Civil Servants (PNS). Using a proportional random sampling technique, 280 respondents were selected to answer the questionnaire as a data collection instrument. Data analysis was carried out through classical assumption tests, simple linear regression, multiple regression, and hypothesis testing, including path analysis. The research results show that leadership and job satisfaction directly influence organizational commitment, with leadership also having a direct influence on job satisfaction. In addition, job satisfaction also mediates the relationship between leadership and organizational commitment, contributing 20.89% in increasing commitment through teacher job satisfaction of 2.52%.

description: We propose a spatio-temporal characterization of the entanglement dynamics in many-body localized (MBL) systems, which exhibits a striking resemblance with dynamical heterogeneity in classical glasses. Specifically, we find that the relaxation times of local entanglement, as measured by the concurrence, are spatially correlated yielding a dynamical length scale for quantum entanglement. As a consequence of this spatio-temporal analysis, we observe that the considered MBL system is made up of dynamically correlated clusters with a size set by this entanglement length scale. The system decomposes into compartments of different activity such as active regions with fast quantum entanglement dynamics and inactive regions where the dynamics is slow. We further find that the relaxation times of the on-site concurrence become broader distributed and more spatially correlated, as disorder increases or the energy of the initial state decreases. Through this spatio-temporal characterization of entanglement, our work unravels a previously unrecognized connection between the behavior of classical glasses and the genuine quantum dynamics of MBL systems.

Study the contributions of S, P, and D-wave resonances to the quasi-two-body decays $B^{0}_{s} \rightarrow ψ(3686,3770)Kπ$ in perturbative QCD approach

description: Based on the perturbative quantum chromodynamics (pQCD) approach and the quasi-two-body approximation, we have studied the three-body decays B^{0}_{s}\rightarrow ψ(3686,3770)\emph{K}π, which include the contributions of the intermediate resonances \bar{\emph{K}}^{*}_{0}(1430)^{0}, \bar{\emph{K}}^{*}(892)^{0}, \bar{\emph{K}}^{*}(1410)^{0}, \bar{\emph{K}}^{*}(1680)^{0}, and \bar{\emph{K}}^{*}_{2}(1430)^{0}. The time-like form factors corresponding to the distribution amplitudes of the S, P, and D-wave of the kaon-pion pair have been adopted in the parameterized form, which describe the interactions between \emph{K} and πin the resonance region. First, the decays B^{0}_{s}\rightarrow ψ(2S,1D)\emph{K}^{-}π^{+} have been calculated followed by the calculation of the branching ratios of the decays B^{0}_{s}\rightarrow ψ(3686,3770)\emph{K}^{-}π^{+} using the 2S-1D mixing scheme. In addition, the pQCD predictions for the decays B^{0}_{s}\rightarrow ψ(2S,1D)\emph{K}πand B^{0}_{s}\rightarrow ψ(3686,3770)\emph{K}πhave been obtained using the narrow-width approximation relation given by the Clebsch-Gorden coefficients. Our work shows that the \bar{\emph{K}}^{*}(892)^{0} resonance is the main contributor to the total decay, and the branching ratio and the longitudinal polarization fraction of the ψ(2S)\bar{\emph{K}}^{*}(892)^{0} decay mode agree well with the currently available data within errors. Furthermore, the theoretical predictions of the ψ(2S) and ψ(3686) decay modes are very close, indicating that they can be regarded as the same meson state. Finally, the pQCD predictions for branching ratios of decays B^{0}_{s}\rightarrow ψ(3686,3770)\emph{K}πare of the order of 10^{-5} and 10^{-6}, respectively, which can be verified using the ongoing LHCb and Belle II experiments.

The results of in vitro test (utilizing brine shrimp Artemia salina LEACH) showed that three extracts ethanol, dichloromethane, and ethanol/water, significantly inhibited Artemia salina with LC50 values ranging from 6.09 to 16.83 µg/mL. Remarkably, the new compound 1 exhibited potent inhibition against both Gram-positive (Staphyloccocus aureus, Bacillus subtilis, Lactobacillus fermentum), and Gram-negative (Escherichia coli, Salmonella enterica, Pseudomonas aeruginosa) bacteria species, with IC50 values of less than 12.0 nM and MIC ranging from 4.70 to 75.23 nM as determined by the broth-microdilution assay.

On fine Selmer groups and signed Selmer groups of elliptic modular forms

description: Let $f$ be an elliptic modular form and $p$ an odd prime that is coprime to the level of $f$. We study the link between divisors of the characteristic ideal of the $p$-primary fine Selmer group of $f$ over the cyclotomic $\mathbb{Z}_p$ extension of $\mathbb{Q}$ and the greatest common divisor of signed Selmer groups attached to $f$ defined using the theory of Wach modules. One of the key ingredients of our proof is a generalization of a result of Wingberg on the structure of fine Selmer groups of abelian varieties with supersingular reduction at $p$ to the context of modular forms.

A new kind of anomaly: on W-constraints for GKM

description: We look for the origins of the single equation, which is a peculiar combination of W-constrains, which provides the non-abelian W-representation for generalized Kontsevich model (GKM), i.e. is enough to fix the partition function unambiguously. Namely we compare it with the scalar projection of the matrix Ward identity. It turns out that, though similar, the two equations do not coincide, moreover, the latter one is non-polynomial in time-variables. This discrepancy disappears for the cubic model if partition function is reduced to depend on odd times (belong to KdV sub-hierarchy of KP), but in general such reduction is not enough. We consider the failure of such direct interpretation of the "single equation" as a new kind of anomaly, which should be explained and eliminated in the future analysis of GKM.

description: Synthesizing many-body interaction Hamiltonian is a central task in quantum simulation. However, it is challenging to synthesize interactions including more than two spins. Borrowing tools from quantum optics, we synthesize five-body spin-exchange interaction in a superconducting quantum circuit by simultaneously exciting four independent qubits with time-energy correlated photon quadruples generated from a qudit. During the dynamic evolution of the five-body interaction, a Greenberger-Horne-Zeilinger state is generated in a single step with fidelity estimated to be $0.685$. We compare the influence of noise on the three-, four- and five-body interaction as a step toward answering the question on the quantum origin of chiral molecules. We also demonstrate a many-body Mach-Zehnder interferometer which potentially has a Heisenberg-limit sensitivity. This study paves a way for quantum simulation involving many-body interactions and high excited states of quantum circuits.

description: Abstract: In the central Rif, as well as in all regions of Morocco, the issue of women is of capital importance, because it constitutes an essential indicator of their real development.

Rural women play an important role in various areas of life. They are the pillar of the family, without which society cannot exist. In addition, they contribute to building the family economy by working outside the home or as organizers of this economy.

This study aims to highlight the reality of rural women in the central Rif of the province of Al Hoceima, through their social and economic empowerment, as well as through the extent of their contribution to economic activity and its impact on territorial development. It has been shown that the efforts made by local actors specialized in the development of rural women remain weak to improve the situation of rural women and their social and economic integration. While we conclude that income from the cannabis plant contributed, albeit relatively, to the improvement of the condition of women. Furthermore, income from cannabis cultivation is not reflected in the social and economic lives of women in relation to the major tasks they perform.

description: We prove that for a bounded domain in $\mathbb C^n$ with the Bergman metric of constant holomorphic sectional curvature being biholomorphic to a ball is equivalent to the hyperconvexity or the exhaustiveness of the Bergman-Calabi diastasis. By finding its connection with the Bergman representative coordinate, we give explicit formulas of the Bergman-Calabi diastasis and show that it has bounded gradient. In particular, we prove that any bounded domain whose Bergman metric has constant holomorphic sectional curvature is Lu Qi-Keng. We also extend a theorem of Lu towards the incomplete situation and characterize pseudoconvex domains that are biholomorphic to a ball possibly less a relatively closed pluripolar set.

description: Magic state distillation is a resource intensive subroutine that consumes noisy input states to produce high-fidelity resource states that are used to perform logical operations in practical quantum-computing architectures. The resource cost of magic state distillation can be reduced by improving the fidelity of the raw input states. To this end, we propose an initialization protocol that offers a quadratic improvement in the error rate of the input magic states in architectures with biased noise. This is achieved by preparing an error-detecting code which detects the dominant errors that occur during state preparation. We obtain this advantage by exploiting the native gate operations of an underlying qubit architecture that experiences biases in its noise profile. We perform simulations to analyze the performance of our protocol with the XZZX surface code. Even at modest physical parameters with a two-qubit gate error rate of $0.7\%$ and total probability of dominant errors in the gate $O(10^3)$ larger compared to that of non-dominant errors, we find that our preparation scheme delivers magic states with logical error rate $O(10^{-8})$ after a single round of the standard 15-to-1 distillation protocol; two orders of magnitude lower than using conventional state preparation. Our approach therefore promises considerable savings in overheads with near-term technology.
