description: The advent of novel opto-genetics technology allows the recording of brain activity with a resolution never seen before. The characterisation of these very large data sets offers new challenges as well as unique theory-testing opportunities. Here we discuss whether the spatial and temporal correlation of the collective activity of thousands of neurons are tangled as predicted by the theory of critical phenomena. The analysis shows that both, the correlation length $ξ$ and the correlation time $τ$ scale as predicted as a function of the system size. With some peculiarities that we discuss, the analysis uncovers new evidence consistent with the view that the large scale brain cortical dynamics corresponds to critical phenomena.

description: We address the problem of coding for classical multiple-access channels (MACs) with the assistance of non-signaling correlations between parties. It is well-known that non-signaling assistance does not change the capacity of classical point-to-point channels. However, it was recently observed that one can construct MACs from two-player non-local games while relating the winning probability of the game to the capacity of the MAC. By considering games for which entanglement increases the winning probability, this shows that for some specific kinds of channels, entanglement between the senders can increase the capacity. We make several contributions towards understanding the capacity region for MACs with the assistance of non-signaling correlations. We develop a linear program computing the optimal success probability for coding over $n$ copies of a MAC $W$ with size growing polynomially in $n$. Solving this linear program allows us to achieve inner bounds for MACs. Applying this method to the binary adder channel, we show that using non-signaling assistance, the sum-rate $1.5425$ can be reached even with zero error, which beats the maximum sum-rate capacity of $1.5$ in the unassisted case. For noisy channels, where the zero-error non-signaling assisted capacity region is trivial, we can use concatenated codes to obtain achievable points in the capacity region. Applied to a noisy version of the binary adder channel, we show that non-signaling assistance still improves the sum-rate capacity. Complementing these achievability results, we give an outer bound on the non-signaling assisted capacity region that has the same expression as the unassisted region except that the channel inputs are not required to be independent. Finally, we show that the capacity region with non-signaling assistance shared only between each sender and the receiver independently is the same as without assistance.

description: Quantum entanglement phase transitions have provided new insights to quantum many-body dynamics. Both disorders and measurements are found to induce similar entanglement transitions. Here, we provide a theoretical framework that unifies these two seemingly disparate concepts and discloses their internal connections. Specifically, we analytically analyze a $d$-dimension free-fermion gas subject to continuous projective measurements. By mapping the Lindblad master equation to the functional Keldysh field theory, we develop an effective theory termed as the time-local Keldysh nonlinear sigma model, which enables us to analytically describe the physics of the monitored system. Our effective theory resembles to that used to describe the disordered fermionic systems. As an application of the effective theory, we study the transport property and obtain a Drude-form conductivity where the elastic scattering time is replaced by the inverse measurement strength. According to these similarities, two different concepts, measurements and disorders, are unified in the same theoretical framework. A numerical verification of our theory and predictions is also provided.

description: As a relatively new form of sport, esports offers unparalleled data availability. Despite the vast amounts of data that are generated by game engines, it can be challenging to extract them and verify their integrity for the purposes of practical and scientific use. Our work aims to open esports to a broader scientific community by supplying raw and pre-processed files from StarCraft II esports tournaments. These files can be used in statistical and machine learning modeling tasks and related to various laboratory-based measurements (e.g., behavioral tests, brain imaging). We have gathered publicly available game-engine generated "replays" of tournament matches and performed data extraction and cleanup using a low-level application programming interface (API) parser library. Additionally, we open-sourced and published all the custom tools that were developed in the process of creating our dataset. These tools include PyTorch and PyTorch Lightning API abstractions to load and model the data. Our dataset contains replays from major and premiere StarCraft II tournaments since 2016. To prepare the dataset, we processed 55 tournament "replaypacks" that contained 17930 files with game-state information. Based on initial investigation of available StarCraft II datasets, we observed that our dataset is the largest publicly available source of StarCraft II esports data upon its publication. Analysis of the extracted data holds promise for further Artificial Intelligence (AI), Machine Learning (ML), psychological, Human-Computer Interaction (HCI), and sports-related studies in a variety of supervised and self-supervised tasks.

description: Among the essential nutrients found in bee pollen, lipids comprise one of its principal and widely researched compounds with variable content and fatty acids composition depending on pollen’s botanical and geographical origin. Although plant source effect on pollen lipids has been partially studied, the impact of geographical origin remains unclear and also, the analysis of polyfloral pollen samples from diverse regions may lead to inaccurate results. Thus, in the present study, monofloral bee pollen samples, Cistus criticus, and Sinapis arvensis, were collected from different areas to identify the effect of geographical origin on pollen lipid profile, excluding the impact of botanical origin. The total lipid content of Cistus pollen ranged from 2.50% to 3.24% and of Sinapis pollen from 7.64% to 9.06%, while statistically significant differences were found among the studied areas, both for the two species. However, it seems that regardless of origin, Sinapis pollen is a rich source of total lipid content, contrary to Cistus pollen. Likely, it was found that geographical origin affected their fatty acid composition. The presence of oleic acid (cis C18:1) was dominant in all Cistus pollen samples and ranged from 50.75% (Central Macedonia) to 65.78% (Attiki), while all Sinapis pollen samples exhibited high content of alpha-linolenic acid (C18:3), with the low average percentage (41.71%) found in Crete and the highest (52.94%) in Central Macedonia. The results showed that the determination of geographical origin effect on lipids profile of bee pollen should be considered for the establishment of global quality criteria.

description: Recently, the LHCb Collaboration reported a near-threshold enhancement, $X(3960)$, in the $D_s^+D_s^-$ invariant mass distribution. We show that the data can be well described by either a bound or a virtual state below the $D_s^+D_s^-$ threshold. The mass given by the pole position is $(3928\pm3)$ MeV. Using this mass and the existing information on the $X(3872)$ and $Z_c(3900)$ resonances, a complete spectrum of the $S$-wave hadronic molecules formed by a pair of ground state charmed and anticharmed mesons is established. Thus, pole positions of the partners of the $X(3872)$, $Z_c(3900)$ and the newly observed $D_s^+D_s^-$ state are predicted. Calculations have been carried out at the leading order of nonrelativistic effective field theory and considering both heavy quark spin and light flavor SU(3) symmetries, though conservative errors from the breaking of these symmetries are provided.

description: Varroasisis caused by Varroa destrucor (Anderson and Trueman) is considered the most dangerous honey bee disease. V. destructor mites parasitize both brood and adults, causing considerable losses to the colony population. The control of Varroa mites is highly dependent on the application of synthetic acaricides, however, acaricide resistance can develop. To eliminate the risk of Varroa mite resistance and to reduce residues in hive products, organic-based substances for Varroa mite control are being applied. In the present study, the acaricidal activity of N-alkyl and O-acyl chitosan derivatives against Varroa mites and their side effects on honey bees have been evaluated. Chitosan has been extracted from the corpses of honey bees. The yield, degree of deacetylation, and molecular weight of chitosan from the chitin of honey bee corpses were determined as 89%, 90%, and 20 kDa, respectively. Varroa mite mortalities were observed between 6.28-84.38% and 0.00-90.47% by N-alkyl and O-acyl chitosan derivatives, respectively. The best derivatives against Varroa mite were N-(3-phenylbutyl)chitosan (NAC-5) and O-(heptanoyl)chitosan (OAC-4). The results showed that different lethal concentrations of NAC-5 and OAC-4 had side effects against honey bees less than 26%. No significant difference was found between honey bee mortalities at 24, 48, and 72 hours post-treatment, while mortalities significantly differed between 4, and 24 h post-treatment. Immune gene expression in honey bees exposed to a lethal concentration of NAC-5and OAC-4 showed that the expressions of AmHym, AmBask, and AmSpz were significantly lower compared with those of control honey bees.

description: We propose a greedy algorithm to select $N$ important features among $P$ input features for a non-linear prediction problem. The features are selected one by one sequentially, in an iterative loss minimization procedure. We use neural networks as predictors in the algorithm to compute the loss and hence, we refer to our method as neural greedy pursuit (NGP). NGP is efficient in selecting $N$ features when $N \ll P$, and it provides a notion of feature importance in a descending order following the sequential selection procedure. We experimentally show that NGP provides better performance than several feature selection methods such as DeepLIFT and Drop-one-out loss. In addition, we experimentally show a phase transition behavior in which perfect selection of all $N$ features without false positives is possible when the training data size exceeds a threshold.

description: Keeping bee colonies is one of the most important sectors of investment in the global agricultural field. Internationally, beekeepers are interested in improving bee feeding methods to maximize the productivity and quality of their products. Whereas the current study aims to develop and evaluate an automatic feeding system that works with solar energy. This technique increases the vertical expansion of beekeeping by designing a multi-shelf mobile apiary for easy transportation as desired. The development process included the inclusion of automated feeders that operate electronically using sensors to provide a nutritional solution for bee colonies without human intervention. Also, the automatic apiary was provided with a sugar solution tank that was equipped with a continuous stirring system that works with a timer. Also, the automatic apiary contains an alarm system and remote mobile contact with the beekeeper in case of depletion of the sugar syrup. The variables under study included three levels of nutritional level volumes of 500, 750, and 1000 ml, respectively, with two stirring periods (3 and 6 times/day) at two concentrations for sugar solution of 50 and 67%. The evaluation process was done during the critical winter period of the year, from December to March. The main results showed that the colonies’ strength had an increment ratio over control hives of 30.23% when using the highest variable levels. Also, the seasonal energy consumption ranged from 1.25–2.81 kWh per season. Therefore, beekeepers can benefit from this novel feeding approach.

description: This paper analyzes how tourism has been used as a geopolitical strategy by the Republic of Ecuador throughout the last century, gaining remarkable relevance in the recent period, being considered as an alternative source of development in the context of the restrictive capacities and resources of the National State. In particular, we analyzed the institutional trajectory of tourism public policies in Ecuador, between 19902020, focusing on the role and form of state action in this process. To this end, an empirical study was carried out, based mainly on secondary data collected from the official press of the Republic of Ecuador, in its three branches (executive, legislative and judiciary). From a total of 19,026 documents initially identified, we reviewed and found a total of 223 normative acts specifically dedicated to the tourism issue. This material was analyzed using the institutional model of public policy analysis elaborated by Pimentel (2011; 2014), structured in 3 dimensions and 5 categories, which deals with the normative, regulatory and cognitive dimensions, drawn upon a synthesis of several categories identified by Scott - among others - on institutional theory. The data showed that: a) there is a clear growth in the volume of national normative acts in the period in question, which suggests that tourism has become a State policy, b) the policies are “initiated” and have the executive as the main participating actor, c) however, they are mostly generic acts and poorly linked to operational actions (with plans, projects and measurement instruments) what suggest that extraofficial actions have been taken in order to promote and operate the sector, and d) they are characterized by the absence of resources to make them feasible. We conclude tourism has become a state policy, in terms of the discursive and also institutional level of official actions taken by the national government, as well as the practice we can see in relation to inbound and domestic flows. However, the way the subject is handled lacks support, especially material and financial one, for its effective execution, which suggests that it may have any other - no official and/or institutional - different force driving the sector, while public policies appear as a shadow on the sector's performance.

description: The recently released Type Ia supernovae (SNe Ia) sample, Pantheon+, is an updated version of Pantheon and has very important cosmological implications. To explore the origin of the enhanced constraining power and internal correlations of datasets in different redshifts, we perform a comprehensively tomographic analysis of the Pantheon+ sample without and with the Cepheid host distance calibration, respectively. Specifically, we take two binning methods to analyze the Pantheon+ sample, i.e., equal redshift interval and equal supernovae number for each bin. For the case of equal redshift interval, after dividing the sample to 10 bins, the first bin in the redshift range $z\in[0.00122, \, 0.227235]$ dominates the constraining power of the whole sample. For the case of equal supernovae number, the first three low redshift bins prefer a large matter fraction $Ω_m$ and only the sixth bin gives a relatively low cosmic expansion rate $H_0$. For both binning methods, we find no obvious evidence of evolution of $H_0$ and $Ω_m$ at the $2\,σ$ confidence level. The inclusion of the SH0ES calibration can significantly compress the parameter space of background dynamics of the universe in each bin. When not considering the calibration, combining the Pantheon+ sample with cosmic microwave background, baryon acoustic oscillations, cosmic chronometers, galaxy clustering and weak lensing data, we give the strongest $1\,σ$ constraint $H_0=67.88\pm0.42$ km s$^{-1}$ Mpc$^{-1}$. However, the addition of the calibration leads to a global shift of the parameter space from the combined constraint and $H_0=68.66\pm0.42$ km s$^{-1}$ Mpc$^{-1}$, which is inconsistent with the Planck-2018 result at about $2\,σ$ confidence level.

description: Image restoration in astronomy has been considered a vital step in many ground-based observational programs that often suffer from sub-optimal seeing due to atmospheric turbulence, distortion of stellar shapes due to instrumental aberrations, trailing, and other issues. It holds importance for various tasks: improved astrometry, deblending of overlapping sources, faint source detection, and identification of point sources near bright extended objects, such as galaxies, to name a few. We conduct an empirical study by applying the Scaled Gradient Projection (SGP) iterative image deconvolution algorithm to restore distorted stellar shapes in our observed data. We investigate using a more flexible divergence measure, the $β$-divergence, which contains the commonly-used Kullback-Leibler (KL) divergence as a special case and allows automatic adaptation of the parameter $β$ to the data. An extensive set of experiments comparing the performance of SGP and its $β$-divergence variant ($β$-SGP) is carried out on extracted star stamps and on images containing multiple stars (both crowded and relatively sparser fields). We show a consistent enhancement in the flux conservation across all considered scenarios using $β$-SGP compared to SGP. Using a few quantifiable metrics such as the Full-Width-at-Half-Maximum (FWHM) and ellipticity of stars, we observe that $β$-SGP improves restoration quality, compared to the SGP, in many cases and still preserves restoration quality in others. We conclude that generalized versions of image restoration algorithms are more robust due to their enhanced flexibility and could be a promising modification for astronomical image restoration.

description: Bumble bees and honey bees are pollinivorous and nectarivorous insects. We classify them as “important pollinators” because of their feeding behaviors. The gut microbiota of these pollinators is essential in nutrition, detoxification, and resistance to diseases. Evaluating the diversity of microbiomes for pollinator taxa may give a chance to understand the ecological relationships among them and the related plants. We investigated the gut bacteria and fungi communities of four taxa distributed in a local steppe-vegetation habitat: wild populations of Bombus terrestris, Bombus niveatus niveatus, Bombus niveatus vorticosus and, as a manageable pollinator, Apis mellifera. The composition of fungi and bacteria within the gut was identified using Illumina MiSeq metabarcoding of the ITS1 and 16S rRNA genes. We found that the dominant bacteria detected in the phyla among the three bumble bee taxa were Firmicutes, Bacteroidota, and Proteobacteria while for A. mellifera, Proteobacteria, Firmicutes, and Bacteroidota, respectively. For fungi, Candida was predominant among bumble bee taxa, whereas Penicillium, Fusarium, and Candida were detected predominantly in A. mellifera.

description: The strict definition of positive geometry implies that all maximal residues of its canonical form are $\pm 1$. We observe, however, that the loop integrand of the amplitude in planar $\mathcal{N}=4$ super Yang-Mills has maximal residues not equal to $\pm 1$. We find the reason for this is that deep in the boundary structure of the loop amplituhedron there are geometries which contain internal boundaries: codimension one defects separating two regions of opposite orientation. This phenomenon requires a generalisation of the concept of positive geometry and canonical form to include such internal boundaries and also suggests the utility of a further generalisation to `weighted positive geometries'. We re-examine the deepest cut of $\mathcal{N}=4$ amplitudes in light of this and obtain new all order residues.

description: An eco-friendly technique for rapid multiplication of the stingless bee colonies, species Heterotrigona itama from Malaysia, to achieve the most effective in vitro queen production is highly needed. In this study, there were significant differences in the volumes of the queen larval food collected from different wild combs (114 µL,127 µL, and 138 µL) at the various sampling sites (F2,44 = 4.85, p < 0.05). While there was no significant difference (i.e. more consistent) in the humidity and temperature readings within the hives, at 68.2%–73.8% (F9,449 = 0.27, p > 0.05) and 24.5 °C–32 °C (F9,449 = 1.73 p > 0.05), respectively. For the rearing process, the optimum parameters were set up based on the optimised data for the first 10 days of the larval food, with the relative humidity (%) of 72 ± 2 and temperature (°C) 27 ± 5, similar to the inside hive values obtained in the field. Several modifications had been made by trial and error due to several reasons. A total of five replicated experiments conducted with three amounts of larval food on the ELISA plates showed that 127 µL and 138 µL gave the best results in the frequency of the hatched queens, with 75% to 77.5% survival. The Kaplan-Meier survival analysis showed significant differences between the amounts of larval food given (χ2 = 10.385, df = 2, p < 0.05) in survival probability, with 138 µL showing the highest. These novel findings specifically obtained for the H. itama species with their optimum food supply, relative humidity, and temperature for in vitro rearing are very valuable for conservation purposes.

description: Searches for the exclusive decays of Higgs and $Z$ bosons into a vector quarkonium state and a photon are performed in the $μ^+μ^- γ$ final state with a proton$-$proton collision data sample corresponding to an integrated luminosity of $139$ fb$^{-1}$ collected at $\sqrt{s}=13$ TeV with the ATLAS detector at the CERN Large Hadron Collider. The observed data are compatible with the expected backgrounds. The 95% confidence-level upper limits on the branching fractions of the Higgs boson decays into $J/ψγ$, $ψ(2S) γ$, and $Υ(1S,2S,3S) γ$ are found to be $2.0\times10^{-4}$, $10.5\times10^{-4}$, and $(2.5,4.2,3.4)\times10^{-4}$, respectively, assuming Standard Model production of the Higgs boson. The corresponding 95% CL upper limits on the branching fractions of the $Z$ boson decays are $1.2\times10^{-6}$, $2.4\times10^{-6}$, and $(1.1,1.3,2.4)\times10^{-6}$. An observed 95% CL interval of $(-133,175)$ is obtained for the $κ_c/κ_γ$ ratio of Higgs boson coupling modifiers, and a 95% CL interval of $(-37,40)$ is obtained for $κ_b/κ_γ$.

description: Finite frames, or spanning sets for finite-dimensional Hilbert spaces, are a ubiquitous tool in signal processing. There has been much recent work on understanding the global structure of collections of finite frames with prescribed properties, such as spaces of unit norm tight frames. We extend some of these results to the more general setting of fusion frames -- a fusion frame is a collection of subspaces of a finite-dimensional Hilbert space with the property that any vector can be recovered from its list of projections. The notion of tightness extends to fusion frames, and we consider the following basic question: is the collection of tight fusion frames with prescribed subspace dimensions path connected? We answer (a generalization of) this question in the affirmative, extending the analogous result for unit norm tight frames proved by Cahill, Mixon and Strawn. We also extend a result of Benedetto and Fickus, who defined a natural functional on the space of unit norm frames (the frame potential), showed that its global minimizers are tight, and showed that it has no spurious local minimizers, meaning that gradient descent can be used to construct unit-norm tight frames. We prove the analogous result for the fusion frame potential of Casazza and Fickus, implying that, when tight fusion frames exist for a given choice of dimensions, they can be constructed via gradient descent. Our proofs use techniques from symplectic geometry and Mumford's geometric invariant theory.

description: The Neotropical Meliponini bees, commonly known as stingless bees, are phylogenetically subdivided into three clades in which the chromosome numbers vary from n = 8 to n = 17. The goal of this study was to identify the major chromosomal rearrangements that occurred during the Neotropical Meliponini (Apidae) karyotypic evolution. In this way, we mapped 18S rDNA and five microsatellites in 33 stingless bee species collected from different Brazilian regions. The species belonged to 15 genera and showed six different chromosome numbers: n = 8, n = 9, n = 11, n = 14, n = 15, and n = 17. The 18S rDNA probe showed a variation from 2 to 12 marked chromosomes in different positions (terminal, subterminal, or centromeric), including 2 B chromosomes out of the 7 B found in Tetragonisca fiebrigi. The microsatellite (GA)15, (GAG)10, (CAA)10, and (TCAGG)6 probes formed clusters on the euchromatic regions of the chromosomes and were useful in the identification of putative Robertsonian fusion events that led to the decrease in the chromosome number during the evolution of the Neotropical Meliponini clade. (TTAGG)6 constituted the telomeric sequence of the analyzed species. The ancestral state of the three Neotropical Meliponini clades is difficult to infer, although, the putative ancestral karyotype probably had a single pair of 18S rDNA cistrons, and the decrease in chromosome number and increase in the 18S rDNA sites occurred independently between genera.

description: We analyze a class of topological static spherically symmetric vacuum solutions in $f(Q)$-gravity. We considered an Ansatz ensuring that those solutions trivially satisfy the field equations of the theory when the non-metricity scalar is constant. In the specific, we provide and discuss local solutions in the form of black holes and traversable wormholes.

description: Honey bees (Apis mellifera) are effective as a sentinel to assess environmental contaminants, particularly particulate matter (PM). Particulate matter (2.5 µm and 10 µm) exposure had deleterious impacts on the foraging performances of Apis mellifera in the treated area, hence expressing an average foraging rate and speed of 3.0 ± 0.13 flowers/min and 4.53 ± 0.45 sec/flower respectively in non-caged plots. Apis dorsata showed a similar pattern in the experimental area and indicated an average rate and speed of 3.39 ± 0.19 flowers/min and 4.46 ± 0.21 sec/flower respectively. A depressed bee population was observed in particulate matter simulated hives, hence reflecting smaller broods and lesser honey storage. The rate of non-emerging offspring cells was high (333.2 ± 48.92 and 200.8 ± 36.63) than non-incense controlled hive boxes (2.6 ± 0.58 and 1.1 ± 0.32) during experimental seasons. The statistical results elucidated a significant relation of PM with larval emergence in incense controlled colonies. The PM substantially degraded the olfaction and flight performance of Apis mellifera visiting bowl traps installed near incense controlled colonies. Comparison between bee visitation rate and bowls installed at 4 feet height asides the boxes were well marked with a high bee visiting rates towards blue and white bowls installed at 4 and 2.5 feet height in controlled territories. An increasing trend of Na (38.51 ± 0.14 and 43.56 ± 0.23) and K (24.99 ± 0.13 and 45.35 ± 0.35) was evidenced in body fluids of Apis mellifera exposed to agro-industrial PM. The interpretations of experimental findings for PM effects on bees’ behaviour and development are discussed for the prevention of these vital pollinators.

description: Integral representations of quantum relative entropy, and of the directional second and higher order derivatives of von Neumann entropy, are established, and used to give simple proofs of fundamental, known data processing inequalities: the Holevo bound on the quantity of information transmitted by a quantum communication channel, and, much more generally, the monotonicity of quantum relative entropy under trace-preserving positive linear maps -- complete positivity of the map need not be assumed. The latter result was first proved by Müller-Hermes and Reeb, based on work of Beigi. For a simple application of such monotonicities, we consider any `divergence' that is non-increasing under quantum measurements, such as the concavity of von Neumann entropy, or various known quantum divergences. An elegant argument due to Hiai, Ohya, and Tsukada is used to show that the infimum of such a `divergence' on pairs of quantum states with prescribed trace distance is the same as the corresponding infimum on pairs of binary classical states. Applications of the new integral formulae to the general probabilistic model of information theory, and a related integral formula for the classical Rényi divergence, are also discussed.

description: This paper describes our contribution to the MIDOG 2022 challenge for detecting mitotic cells. One of the major problems to be addressed in the MIDOG 2022 challenge is the robustness under the natural variance that appears for real-life data in the histopathology field. To address the problem, we use an adapted YOLOv5s model for object detection in conjunction with a new Domain Adaption Classifier (DAC) variant, the Radial-Prediction-DAC, to achieve robustness under domain shifts. In addition, we increase the variability of the available training data using stain augmentation in HED color space. Using the suggested method, we obtain a test set F1-score of 0.6658.
