description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: The negative solution to the famous problem of $36$ officers of Euler implies that there are no two orthogonal Latin squares of order six. We show that the problem has a solution, provided the officers are entangled, and construct orthogonal quantum Latin squares of this size. As a consequence, we find an example of the long-elusive Absolutely Maximally Entangled state AME$(4,6)$ of four subsystems with six levels each, equivalently a $2$-unitary matrix of size $36$, which maximizes the entangling power among all bipartite unitary gates of this dimension, or a perfect tensor with four indices, each running from one to six. This special state deserves the appellation golden AME state as the golden ratio appears prominently in its elements. This result allows us to construct a pure nonadditive quhex quantum error detection code $(\!(3,6,2)\!)_6$, which saturates the Singleton bound and allows one to encode a $6$-level state into a triplet of such states.

description: We have carried out a systematic search for recoiling supermassive black holes (rSMBH) using the Chandra Source and SDSS Cross Matched Catalog. From the survey, we have detected a potential rSMBH, 'CXO J101527.2+625911' at z=0.3504. The CXO J101527.2+625911 has a spatially offset (1.26$\pm$0.05 kpc) active SMBH and kinematically offset broad emission lines (175$\pm$25 km s$^{\rm -1}$ relative to systemic velocity). The observed spatial and velocity offsets suggest this galaxy could be a rSMBH, but we also have considered a possibility of dual SMBH scenario. The column density towards the galaxy center was found to be Compton thin, but no X-ray source was detected. The non-detection of the X-ray source in the nucleus suggests either there is no obscured actively accreting SMBH, or there exists an SMBH but has a low accretion rate (i.e. low-luminosity AGN (LLAGN)). The possibility of the LLAGN was investigated and found to be unlikely based on the H$α$ luminosity, radio power, and kinematic arguments. This, along with the null detection of X-ray source in the nucleus supports our hypothesis that the CXO J101527.2+625911 is a rSMBH. Our GALFIT analysis shows the host galaxy to be a bulge-dominated elliptical. The weak morphological disturbance and small spatial and velocity offsets suggest that CXO J101527.2+625911 could be in the final stage of merging process and about to turn into a normal elliptical galaxy.

Individual vs Collective Forms of Sharing Ownership in Israel

Subjects: Agribusiness

description: This paper compares the development within Israel of four forms of ownership: the rural commune, or "kibbutz;" the more individualistic rural cooperative, the "moshav;" the worker cooperatives of Israel's cities; and enterprises owned collectively by the trade union federation. These forms of ownership are compared by three criteria: 1) their ability to attract and retain founders, sponsors, and members; 2) how long they survive; and 3) whether organizations that do survive lose their cooperative character as they age. By these criteria, the record of the kibbutzim is generally best, while that of the worker cooperatives is generally viewed as being the worst. These results are largely attributable to the concrete institutional environment in which these organizations were being created. For both ideological and practical reasons, the makers of Israel's labor economy always favored rural cooperatives over urban ones, and preferred more centralized and collective forms of cooperative ownership to more individualistic ones.

description: Ο κύριος σκοπός αυτής της εργασίας είναι να διερευνήσει τη συμβολή που μπορεί να έχει το αστικό πράσινο στους κατοίκους της περιοχής της Νάουσας, αλλά και στο οικοσύστημα της περιοχής. Η μεθοδολογία βασίσθηκε σε δύο προσεγγίσεις. 1) Μέσω ερωτηματολογίου για τις απόψεις των πολιτών, πάνω στον αντίκτυπο που έχει το άλσος του Αγίου Νικολάου στην ζωή τους και 2) δεύτερο και πιο εκτενές σε άποψη χρόνου αλλά και πιο άμεσο με αποτελέσματα, ήταν μέσω μετρήσεων μικροκλιματικών παραμέτρων στο πεδίο. Όπου για τριάντα μέρες κατά την διάρκεια των δύο μηνών του Ιουλίου – Αυγούστου 2024, πραγματοποιούνταν μετρήσεις της σχετικής υγρασίας και της θερμοκρασίας, σε πέντε διαφορετικά σημεία εντός του Αγίου Νικολάου και στη συνέχεια συγκρίνονταν με τις αντίστοιχες των τριών πόλεων της περιοχής (Νάουσα, Βέροια, Θεσσαλονίκη) για να προσδιοριστεί η διαφορά που ενδεχομένως να προκαλεί το πράσινο στο περιβάλλον. Τα αποτελέσματα της έρευνας έδειξαν, και με βάση τις απόψεις των πολιτών, και με βάση τις μετρήσεις πεδίου, ότι η συνεισφορά του άλσους είναι πολύ σημαντική.
description: The main purpose of this thesis is to research the contribution that urban green might have to the people of the area of Naousa and also to its ecosystem. The methodology followed is based on two approximations. Firstly, via questionnaire about the opinion of the citizens, on the impact that the Forest of Saint Nicolaos has on their lives, and second and more extended regarding the time needed to complete and also more direct on the results, was via measuring the microclimate parameters on the field. Where, for 30 days during the two summer months of July and August of 2024, measurements were being accomplished and after, being compared with those of the 3 nearest cities (of Naousa, Veria, and Thessaloniki), so as to be specified the difference that might probably cause the grove to the environment. The results of the research showed that, regarding the people’s opinion and the measurements on the field, the contribution of the forest is remarkable.

description: Competition between unitary dynamics that scrambles quantum information non-locally and local measurements that probe and collapse the quantum state can result in a measurement-induced entanglement phase transition. Here we study this phenomenon in an analytically tractable all-to-all Brownian hybrid circuit model composed of qubits. The system is initially entangled with an equal sized reference, and the subsequent hybrid system dynamics either partially preserves or totally destroys this entanglement depending on the measurement rate. Our approach can access a variety of entropic observables which are distinguished by the averaging procedure, and for concreteness we focus on a particular purity quantity for which the averaging is particularly simple. We represent the purity as a path integral coupling four replicas with twisted boundary conditions. Saddle-point analysis reveals a second-order phase transition corresponding to replica permutation symmetry breaking below a critical measurement rate. The transition is mean-field-like and we characterize the critical properties near the transition in terms of a simple Ising field theory in 0+1 dimensions. In addition to studying the purity of the entire system, we study subsystem purities and relate these results to manifestations of quantum error correction in the model. We also comment on the experimental feasibility for simulating this averaged purity, and corroborate our results with exact diagonalization for modest system sizes.

description: The spin-pumping mechanism is probed through a tunnelling MgO interlayer in Fe/Pt bilayers. We show by ferromagnetic resonance technique and spin-pumping experiments that spin currents can tunnel through the MgO interlayer for thickness up to 2~{nm} and can produce significant voltages in the Pt layer. The electrical detection of spin-pumping furthermore reveals the critical role of rectification and shunting effects on the generated voltages. The non zero spin current transport through a few monolayers of an insulating interlayer might initiate further studies on the role of very thin oxides in spin-pumping experiments.

description: Researching kibbutz changes in a two-year study of 34 kibbutzim through referents, interviews, economic and demographic data and documents, enabled the author to discern three main trends: privatization in consumption, interweaving with the surroundings, and managerialism. These trends are related to a deepening comprehensive crisis the kibbutzim have been undergoing since the mid 1980s. Differing types of attitudes among social groups suggest differential seeking of autonomy. The rank and file seek independence from the managers, while managers try to reinforce their independence from public control. Both increase personal options through the interweaving process. A creeping unintended transformation produces an incipient split in the kibbutz identity as a geographical unity and a communal association. This split develops through reciprocal service supplies with the surroundings and diversification of population in the kibbutz. The conclusion points to diversification among kibbutzim in external interweaving, basic social structure, distribution system, and identity as community or organization.

description: The development of a future, global quantum communication network (or quantum internet) will enable high rate private communication and entanglement distribution over very long distances. However, the large-scale performance of ground-based quantum networks (which employ photons as information carriers through optical-fibres) is fundamentally limited by fibre quality and link length, with the latter being a primary design factor for practical network architectures. While these fundamental limits are well established for arbitrary network topologies, the question of how to best design global architectures remains open. In this work, we introduce a large-scale quantum network model called weakly-regular architectures. Such networks are capable of idealising network connectivity, provide freedom to capture a broad class of spatial topologies and remain analytically treatable. This allows us to investigate the effectiveness of large-scale networks with consistent connective properties, and unveil critical conditions under which end-to-end rates remain optimal. Furthermore, through a strict performance comparison of ideal, ground-based quantum networks with that of realistic satellite quantum communication protocols, we establish conditions for which satellites can be used to outperform fibre-based quantum infrastructure; {rigorously proving the efficacy of satellite-based technologies for global quantum communications.

description: The role of rural women in Greece is changing gradually within a broad framework of socio-economic transformations the rural sector has been facing in the recent years. This article is concerned with the broadening of rural women's activities to include matters of public life such as the women's agritouristic cooperatives. The moving force behind the development of these cooperatives has been the General Secretariat for Equality as a way to make known the socio-economic role of women in rural communities and to enhance their income. The first cooperative of this type was established in 1984 in Petra, a small village in the island of Lesvos. In its twelve years of existence, this project has seen the smooth shift of this community from an agricultural economy to an agritouristic one, a pattern that has been quite fulfilling in terms of occupation and income for the local population.

description: We derive the 0.01 $μ$m binned transmission spectrum, between 0.74 and 1.0 $μ$m, of WASP-80b from low resolution spectra obtained with the FORS2 instrument attached to ESO's Very Large Telescope. The combination of the fact that WASP-80 is an active star, together with instrumental and telluric factors, introduces correlated noise in the observed transit light curves, which we treat quantitatively using Gaussian Processes. Comparison of our results together with those from previous studies, to theoretically calculated models reveals an equilibrium temperature in agreement with the previously measured value of 825K, and a sub-solar metallicity, as well as an atmosphere depleted of molecular species with absorption bands in the IR ($\gg 5σ$). Our transmission spectrum alone shows evidence for additional absorption from the potassium core and wing, whereby its presence is detected from analysis of narrow 0.003 $μ$m bin light curves ($\gg 5σ$). Further observations with visible and near-UV filters will be required to expand this spectrum and provide more in-depth knowledge of the atmosphere. These detections are only made possible through an instrument-dependent baseline model and a careful analysis of systematics in the data.

description: Besides the widely known types of cooperative rural communities of Israel, the kibbutz, the moshav ovdim, and the moshav shitufi, there exists another one: the cooperative village (kfar shitufi, in Hebrew).1 Its farmers, lessees of state-owned land, are bound to be members of the local village cooperative. This supplies the services required for farming, at least provision of inputs and marketing of outputs, and members are obliged to use them. Social or municipal services may be provided by the cooperative or by a separate body. Residence in the community is not restricted to members of the cooperative. Neither members nor other residents are expected to hold identical sociopolitical beliefs. Cooperation is a central tenet only in the area of farming. All other aspects of communal life are adaptable to changing conditions of place and time. Flexibility is the prominent aspect of the cooperative village compared to the other types of rural cooperative communities in Israel.

description: In this paper the model for a highly viscous droplet sliding down an inclined plane is analyzed. It is shown that, provided the slope is not too steep, the corresponding moving boundary problem possesses classical solutions. Well-posedness is lost when the relevant linearization ceases to be parabolic. This occurs above a critical incline which depends on the shape of the initial wetted region as well as on the liquid's mass. It is also shown that translating circular solutions are asymptotically stable if the kinematic boundary condition is given by an affine functionand provided the incline is small.

description: End-user service composition is a promising way to ensure flexible, quick and personalized information provision and utilization, and consequently to better cope with spontaneous business requirements. For end-users to compose services directly, issues like service granularity, service organization and business level semantics are critical. End-users will certainly be at loss if they have to select from a long list of available Web services expressed in IT jargons. This article introduces the concept of personalized active service spaces and focuses on the use of business services, service dependency rules, and service personalization rules to support end-user service composition. It addresses two key issues in end-user composition: how to utilize the user preference and context to restrict the scope of applicable services for selection, and how to capture and utilize dependencies or usage patterns between services in order to provide guidance and enforce temporal/sequential restrictions on service invocations for end-user service compositions.

description: Due to its promise to alleviate information overload, text summarization has attracted the attention of many researchers. However, it has remained a serious challenge. Here, we first prove empirical limits on the recall (and F1-scores) of extractive summarizers on the DUC datasets under ROUGE evaluation for both the single-document and multi-document summarization tasks. Next we define the concept of compressibility of a document and present a new model of summarization, which generalizes existing models in the literature and integrates several dimensions of the summarization, viz., abstractive versus extractive, single versus multi-document, and syntactic versus semantic. Finally, we examine some new and existing single-document summarization algorithms in a single framework and compare with state of the art summarizers on DUC data.
Unique continuation principles and their absence for Schrödinger eigenfunctions on combinatorial and quantum graphs and in continuum space

description: For the analysis of the Schrödinger and related equations it is of central importance whether a unique continuation principle (UCP) holds or not. In continuum Euclidean space quantitative forms of unique continuation imply Wegner estimates and regularity properties of the integrated density of states (IDS) of Schrödinger operators with random potentials. For discrete Schrödinger equations on the lattice only a weak analog of the UCP holds, but it is sufficient to guarantee the continuity of the IDS. For other combinatorial graphs this is no longer true. Similarly, for quantum graphs the UCP does not hold in general and consequently, the IDS does not need to be continuous.
Formalizing the Four-layer Metamodeling Stack -- Potential and Benefits

Subjects: subject: Software Engineering (cs.SE)
subject: FOS: Computer and information sciences

description: Enterprise modeling deals with the increasing complexity of processes and systems by operationalizing model content and by linking complementary models and languages, thus amplifying the model-value beyond mere comprehensible pictures. To enable this amplification and turn models into computer-processable structures a comprehensive formalization is needed. This paper presents a generic formalism based on typed first-order logic and provides a perspective on the potential and benefits arising for a variety of research issues in conceptual modeling. We define modeling languages as formal languages with a signature $Σ$ - comprising object types, relation types, and attributes through types and function symbols - and a set of constraints. Three cases studies are included to show the effectiveness of the approach. Applying the formalism to the next level in the hierarchy of models we create M2FOL, a formal modeling language for metamodels. We show that M2FOL is self-describing and therefore complete the formalization of the full four-layer metamodeling stack. On the basis of our generic formalism applicable to arbitrary modeling languages we examine three current research topics - language interleaving & consistency, operations on models, and automatic translation of formalizations to platform-specific code - and how to approach them with the proposed formalism. This shows that the rich knowledge stack on formal languages in logic offers new tools for old problems.

Planetary Chaos and the (In)stability of Hungaria Asteroids

description: The Hungaria asteroid group is located interior to the main asteroid belt, with semimajor axes between 1.8 and 2 AU, low eccentricities and inclinations of 16-35 degrees. Recently, it has been proposed that Hungaria asteroids are a secularly declining population that may be related to the Late Heavy Bombardment (LHB) impactors (Ćuk et al. 2012, Bottke et al. 2012). While Ćuk et al. (2012) and Bottke et al. (2012) have reproduced a Hungaria-like population that declined exponentially, the real Hungarias were never confirmed to be unstable to the same degree. Here we find that the stability of Hungarias is strongly dependent on the evolution of the eccentricity of Mars, which is chaotic and unpredictable on Gyr timescales. We find that the high Martian eccentricity chiefly affects Hungarias through close approaches with Mars, rather than planetary secular modes. However, current minimum perihelia of Hungarias (over Myr timescales) are not diagnostic of their long-term stability due to a number of secular and mean motion resonances affecting the Hungaria region (Milani et al. 2010). We conclude that planetary chaos makes it impossible to determine the effective lifetimes of observed Hungarias. Furthermore, long-term changes of Martian eccentricity could lead to variable Hungaria loss over time. We speculate that some of the most stable Hungarias may have been placed in their present orbit when the eccentricity of Mars was significantly higher than today.

description: This work considers artificial feed-forward neural networks as parametric approximators in optimal control of discrete-time systems. Two different approaches are introduced to take polytopic input constraints into account. The first approach determines (sub-)optimal inputs by the application of gradient methods. Closed-form expressions for the gradient of general neural networks with respect to their inputs are derived. The approach allows to consider state-dependent input constraints, as well as to ensure the satisfaction of state constraints by exploiting recursive reachable set computations. The second approach makes use of neural networks with softmax output units to map states into parameters, which determine (sub-)optimal inputs by a convex combination of the vertices of the input constraint set. The application of both approaches in model predictive control is discussed, and results obtained for a numerical example are used for illustration.

description: We report high pressure studies of the structural stability of Ru2Sn3, a new type of three dimensional topological insulator (3D-TI) with unique quasi-one dimensional Dirac electron states throughout the surface Brillouin zone of its one-atmosphere low temperature orthorhombic form. Our in-situ high-pressure synchrotron x-ray diffraction and electrical resistance measurements reveal that upon increasing pressure the tetragonal to orthorhombic shifts to higher temperature. We find that the stability of the orthorhombic phase that hosts the non-trivial topological ground state can be pushed up to room temperature by an applied pressure of ~ 20 GPa. This is in contrast to the commonly known 3D-TIs whose ground state is usually destroyed under pressure. Our results indicate that pressure provides a possible pathway for realizing a room-temperature topological insulating state in Ru2Sn3.

There is rapidly growing evidence that dense active and living systems also exhibit many features of glassy behavior, but it is still largely unknown how physical aging is manifested in such active glassy materials. Our goal is to explore whether active and passive thermal glasses age in fundamentally different ways. To address this, we numerically study the aging dynamics following a quench from high to low temperature for two-dimensional passive and active Brownian model glass-formers. We find that aging in active thermal glasses is governed by a time-dependent competition between thermal and active effects, with an effective temperature that explicitly evolves with the age of the material. Moreover, unlike passive aging phenomenology, we find that the degree of dynamic heterogeneity in active aging systems is relatively small and remarkably constant with age. We conclude that the often-invoked mapping between an active system and a passive one with a higher effective temperature rigorously breaks down upon aging, and that the aging dynamics of thermal active glasses differs in several distinct ways from both the passive and athermal active case.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Semi-supervised node classification on graphs is an important research problem, with many real-world applications in information retrieval such as content classification on a social network and query intent classification on an e-commerce query graph. While traditional approaches are largely transductive, recent graph neural networks (GNNs) integrate node features with network structures, thus enabling inductive node classification models that can be applied to new nodes or even new graphs in the same feature space. However, inter-graph differences still exist across graphs within the same domain. Thus, training just one global model (e.g., a state-of-the-art GNN) to handle all new graphs, whilst ignoring the inter-graph differences, can lead to suboptimal performance. In this paper, we study the problem of inductive node classification across graphs. Unlike existing one-model-fits-all approaches, we propose a novel meta-inductive framework called MI-GNN to customize the inductive model to each graph under a meta-learning paradigm. That is, MI-GNN does not directly learn an inductive model; it learns the general knowledge of how to train a model for semi-supervised node classification on new graphs. To cope with the differences across graphs, MI-GNN employs a dual adaptation mechanism at both the graph and task levels. More specifically, we learn a graph prior to adapt for the graph-level differences, and a task prior to adapt for the task-level differences conditioned on a graph. Extensive experiments on five real-world graph collections demonstrate the effectiveness of our proposed model.

description: We show that any closed oriented immersed Hamiltonian stationary isotropic surface $Σ$ with genus $g_Σ$ in $S^{5}\subset\mathbb{C}^{3}$ is (1) Legendrian and minimal if $g_Σ=0$; (2) either Legendrian or with exactly $2g_Σ-2$ Legendrian points if $g_Σ\geq1.$ In general, every compact oriented immersed isotropic submanifold $L^{n-1}\subset S^{2n-1}\subset\mathbb{C}^{n}$ such that the cone $C\left( L^{n-1}\right) $ is Hamiltonian stationary must be Legendrian and minimal if its first Betti number is zero. Corresponding results for non-orientable links are also provided.

Burkhardt-Cottingham-type sum rules for light-cone and quasi-PDFs

description: The Burkhardt-Cottingham (BC) sum rule connects the twist-3 light-cone parton distribution function (PDF) $g_{T}(x)$ to the twist-2 helicity PDF $g_{1}(x)$. The chiral-odd counterpart of the BC sum rule relates the twist-3 light-cone PDF $h_{L}(x)$ to the twist-2 transversity PDF $h_{1}(x)$. These BC-type sum rules can also be derived for the corresponding quasi-PDFs. We perform a perturbative check of the BC-type sum rules in the quark target model and the Yukawa model, by going beyond the ultra-violet (UV) divergent terms. We employ dimensional regularization (DR) and cut-off schemes to regulate UV divergences, and show that the BC-type sum rules hold for DR, while they are generally violated when using a cut-off. This violation can be traced back to the breaking of rotational invariance. We find corresponding results for the sum rule relating the mass of the target to the twist-3 PDF $e(x)$. Moreover, we supplement our analytical results with numerical calculations.

description: Eclipsing binaries offer a unique opportunity to determine basic stellar properties. With the advent of wide-field camera and all-sky time-domain surveys, thousands of eclipsing binaries have been charted via light curve classification, yet their fundamental properties remain unexplored, mainly due to the extensive efforts needed for spectroscopic follow-ups. In this paper we present the discovery of a short period (P=0.313 days) double-lined M-dwarf eclipsing binary, CSSJ114804.3+255132/SDSSJ114804.35+255132.6, by cross-matching binary light curves from Catalina Sky Surveys and spectroscopically classified M dwarfs from Sloan Digital Sky Survey. We obtain follow-up spectra using Gemini telescope, enabling us to determine the mass, radius, and temperature of the primary and secondary component to be M1 = 0.47\pm0.03(statistic)\pm0.03(systematic) M_sun, M2 = 0.46\pm0.03(statistic)\pm0.03(systematic) M_sun, R1 = 0.52\pm0.08(statistic)\pm0.07(systematic) R_sun, R2 = 0.60\pm0.08(statistic)\pm0.08(systematic) R_sun, T1 = 3560\pm100 K, and T2 = 3040\pm100 K, respectively. The systematic error was estimated using the difference between eccentric and non-eccentric fit. Our analysis also indicates that there is definitively 3rd-light contamination (66%) in the CSS photometry. The secondary star seems inflated, probably due to tidal locking of the close secondary companion, which is common for very short period binary systems. Future spectroscopic observations with high resolution will narrow down the uncertainties of stellar parameters for both component, rendering this system as a benchmark in studying fundamental properties of M dwarfs.

description: The spectral efficiency of wireless networks can be made nearly infinitely large by deploying many antennas, but the deployment of very many antennas requires new topologies beyond the compact and discrete antenna arrays used by conventional base stations. In this paper, we consider the large intelligent surface scenario where small antennas are deployed on a large and dense two-dimensional grid. Building on the heritage of MIMO, we first analyze the beamwidth and sidelobes when transmitting from large intelligent surfaces. We compare different precoding schemes and determine how to optimize the transmit power with respect to different utility functions.

description: Hyper-Wiener index was introduced as one of the main generalizations of the well known Wiener index. Through the years properties of the Wiener index have been extensively studied in both Mathematics and Chemistry. The Hyper-Wiener index, although received much attention, is far from being thoroughly examined due to its complex definition. We consider the local version of the Hyper-Wiener index ($WW(G)$), defined as $ww_G(v)=\sum\limits_{u\in V(G)}(d^2(u,v)+d(u,v))$ for a vertex $v$ in a graph $G$, in trees. For established results on the Wiener index ($W(.)$), we present analogous studies on $WW(.)$. In addition to interesting observations, some conjectures and questions are also proposed.

description: To evaluate the role of common substrates in the transmission of respiratory viruses, uniformly distributed microdroplets of artificial saliva were generated using an advanced inkjet printing technology to replicate the aerosol droplets, and subsequently deposited on five substrates, including glass, PTFE, stainless steel, ABS, and melamine. The droplets were found to evaporate within a short timeframe, which is consistent with previous reports concerning the drying kinetics of picolitre droplets. Using fluorescence microscopy and atomic force microscopy, we found that the surface deposited microdroplet nuclei present two distinctive morphological features as the result of their drying mode, which is controlled by both interfacial energy and surface roughness. Nanomechanical measurements confirm that the nuclei deposited on all substrates possess similar surface adhesion and Youngs modulus, supporting the proposed coreshell structure of the nuclei. We suggest that appropriate antiviral surface strategies, e.g. functionalisation, chemical deposition, could be developed to modulate the evaporation process of microdroplet nuclei, and subsequently mitigate the possible surface viability and transmissibility of respiratory virus.
