description: In this paper, we generalize finite depth wavelet scattering transforms, which we formulate as $\Lb^q(\mathbb{R}^n)$ norms of a cascade of continuous wavelet transforms (or dyadic wavelet transforms) and contractive nonlinearities. We then provide norms for these operators, prove that these operators are well-defined, and are Lipschitz continuous to the action of $C^2$ diffeomorphisms in specific cases. Lastly, we extend our results to formulate an operator invariant to the action of rotations $R \in \text{SO}(n)$ and an operator that is equivariant to the action of rotations of $R \in \text{SO}(n)$.

description: Treating instrumentally inseminated honey bee queens with carbon dioxide accelerates egg laying. This treatment also activates the ovaries of virgins. The aim of the study was to compare the effect of three different treatments: (1) anaesthesia with carbon dioxide, (2) anaesthesia with nitrogen, and (3) oxygen deprivation by submersion in water, on the onset of oviposition in virgin queens. The effect of the number and duration of CO2 treatments was also investigated. No significant differences were found in the onset of egg laying in queens treated with CO2, or N2, or water. The beginning of oviposition after the CO2 treatment for 0.1, 1, 2, and 10 min, did not differ significantly. Whether a CO2 treatment was performed twice or three times, the effect was the same, but oviposition was accelerated compared to when only one anaesthesia treatment was used. I speculate that ovary activation in queens is not the effect of CO2 or any other gases but rather the effect of a lack of oxygen, i.e., anoxia.

description: Thin sheets respond to confinement by smoothly wrinkling, or by focusing stress into small, sharp regions. From engineering to biology, geology, textiles, and art, thin sheets are packed and confined in a wide variety of ways, and yet fundamental questions remain about how stresses focus and patterns form in these structures. Using experiments and molecular dynamics (MD) simulations, we probe the confinement response of circular sheets, flattened in their central region and quasi-statically drawn through a ring. Wrinkles develop in the outer, free region, then are replaced by a truncated cone, which forms in an abrupt transition to stress focusing. We explore how the force associated with this event, and the number of wrinkles, depend on geometry. Additional cones sequentially pattern the sheet, until axisymmetry is recovered in most geometries. The cone size is sensitive to in-plane geometry. We uncover a coarse-grained description of this geometric dependence, which diverges depending on the proximity to the asymptotic d-cone limit, where the clamp size approaches zero. This work contributes to the characterization of general confinement of thin sheets, while broadening the understanding of the d-cone, a fundamental element of stress focusing, as it appears in realistic settings.

description: The matrix element method is widely considered the ultimate LHC inference tool for small event numbers. We show how a combination of two conditional generative neural networks encodes the QCD radiation and detector effects without any simplifying assumptions, while keeping the computation of likelihoods for individual events numerically efficient. We illustrate our approach for the CP-violating phase of the top Yukawa coupling in associated Higgs and single-top production. Currently, the limiting factor for the precision of our approach is jet combinatorics.

description: The effect of gamma radiation on the whole body contents of fatty acids and elemental composition were investigated for honey bee workers Apis mellifera. The data indicated that the quantities of fatty acids and elemental composition within the whole body of the workers of A. mellifera were affected significantly especially at the dose of 20 rad. Data obtained indicated that the palmitic (C16:0), oleic (C18:1) and linolic (C18:2) acids increased when workers irradiated with 20 rad. Analysis of the 7 elements; Mg, P, K, Ca, Fe, Cu and Zn were detected by energy dispersive X- ray analyzer by using (EDX). The most dominant elements in control workers were K followed by P; the Fe occupied the last order. In irradiated adult workers with 20 rad, K recorded a higher percentage than its control. In the same dose (20 rad), the total heavy metals Copper + Zink (Cu + Zn) decreased from 19.81% to 14.8%.

description: Social wasps are significant pests of bees and other sectors of agriculture and are also insects of health interest importance. They are eusocial, because of the overlapping of generations; they care cooperatively the brood and show reproductive caste differentiation. The purpose of this study was to improve the effectiveness of the colored hive-type traps and find the color that removes the greater number of wasps. Two sets of three hive-type traps in pink, yellow and white color were placed next to two apiaries consisting of 30 colonies each on the campus of the Agricultural University of Athens. Fish canned cat food was used as bait. Once a week the wasp samples were collected and stored in the freezer, while the protein bait was replaced and there was a circular rotation of the colored traps. Vespa orientalis samples were collected at a rate of 75%, Vespula germanica at a rate of 22%, and Polistes spp. at a rate of 3%. The pink color was the most attractive, followed by yellow and white. The average weekly number of trappings per month of V. orientalis and Polistes spp. was high in July and August, favored by high temperatures, low precipitation, and low atmospheric humidity, while V. germanica was trapped more in November. Although color hive-type traps are promising for wasp control, further research is suggested.

description: We present a robust system for state estimation that fuses measurements from multiple lidars and inertial sensors with GNSS data. To initiate the method, we use the prior GNSS pose information. We then perform incremental motion in real-time, which produces robust motion estimates in a global frame by fusing lidar and IMU signals with GNSS translation components using a factor graph framework. We also propose methods to account for signal loss with a novel synchronization and fusion mechanism. To validate our approach extensive tests were carried out on data collected using Scania test vehicles (5 sequences for a total of ~ 7 Km). From our evaluations, we show an average improvement of 61% in relative translation and 42% rotational error compared to a state-of-the-art estimator fusing a single lidar/inertial sensor pair.

description: In recent years, high losses of Western honey bee (Apis mellifera) colonies have been reported in the United States. Because honey bees are important to agricultural systems, it is critical to document when high losses occur and to explore patterns of loss among beekeeper subgroups. We used a voluntary, retrospective questionnaire to ask U.S. beekeepers (backyard, sideline, and commercial) about their colony loss during the 2020–21 and 2021–22 beekeeping seasons. We found that U.S. beekeepers lost 50.8% (38.0–63.1; 95% b.CI) of their colonies in 2020–21, the highest annual (year-long) loss reported to date. During the following year, 2021–22, beekeepers lost 39.0% (31.5–47.9; 95% b.CI) of their colonies, which is close to the average of previously published annual loss rates (40.9%). In contrast to previous years, backyard beekeepers (managing 50 or fewer colonies) had an elevated summer loss across both years and commercial beekeepers (managing >500 colonies) reported “weather” as an important cause of colony loss in the summer of 2021. Our results show that severe colony losses still occur periodically. From these data on colony loss rates, it does not appear that the health of honey bee colonies in the U.S. has improved since this survey began in 2008. We suggest that research should continue to focus on stressors that beekeepers most often perceive to be leading causes of loss—Varroa destructor mites, queen issues, and weather.

description: Applying the Fedosov connections constructed in our previous work, we find a (dense) subsheaf of smooth functions on a Kähler manifold $X$ which admits a non-formal deformation quantization. When $X$ is prequantizable and the Fedosov connection satisfies an integrality condition, we prove that this subsheaf of functions can be quantized to a sheaf of twisted differential operators (TDO), which is isomorphic to that associated to the prequantum line bundle. We also show that examples of such quantizable functions are given by images of quantum moment maps.

description: As a population grows, spreading to new environments may favor specialization. In this paper, we introduce and explore a model for specialization at the front of a colony expanding synchronously into new territory. We show through numerical simulations that, by gaining fitness through accumulating mutations, progeny of the initial seed population can differentiate into distinct specialists. With competition and selection limited to the growth front, the emerging specialists first segregate into sectors, which then expand to dominate the entire population. We quantify the scaling of the fixation time with the size of the population and observe different behaviors corresponding to distinct universality classes: unbounded and bounded gains in fitness lead to superdiffusive ($z=3/2$) and diffusive ($z=2$) stochastic wanderings of the sector boundaries, respectively.

description: In recent years, bee pollen has been widely used as a dietary supplement due to its high nutritional value. However, the quality of the final product is strongly affected by the practices followed by beekeepers during the collection process. In Greece, bee pollen is mostly marketed and consumed in fresh form. In the present study, the harvesting period under different environmental conditions, the use of different types of pollen traps [outdoor front (A), indoor bottom (B) and indoor roof (C)] and the time staying in them (0,1,2 days) were evaluated as possible sources of contamination of the final product. Microbial load variability was studied for Mesophilic Total Viable Count (MTVC), Yeasts and Moulds (Y&M), Enterobacteriaceae (ENT), Lactic Acid Bacteria (LAB) and Escherichia coli. The results of the study highlight the advantages of using indoor traps and suggest avoiding early spring collection. Delayed harvesting had an impact on the microbial load of pollen, especially on the growth of MTVC and ENT, with values higher than 5 and 2 log cfu/g, respectively, exceeding the market limits as defined in food hygiene standards. Indeed, the highest counts of MTVC and ENT were detected after 2 days of pollen staying in outdoor front traps (5.98 and 4.81 log cfu/g, respectively). The results of the study will be a helpful guide in giving the appropriate beekeeping practices for the production of fresh pollen with microbial load harmonized with hygienic standards.
On the number of even values of an eta-quotient

description: The goal of this note is to provide a general lower bound on the number of even values of the Fourier coefficients of an arbitrary eta-quotient $F$, over any arithmetic progression. Namely, if $g_{a,b}(x)$ denotes the number of even coefficients of $F$ in degrees $n\equiv b$ (mod $a$) such that $n\le x$, then we show that $g_{a,b}(x) / \sqrt{x}$ is unbounded for $x$ large. Note that our result is very close to the best bound currently known even in the special case of the partition function $p(n)$ (namely, $\sqrt{x}\log \log x$, proven by Bellaïche and Nicolas in 2016). Our argument substantially relies upon, and generalizes, Serre's classical theorem on the number of even values of $p(n)$, combined with a recent modular-form result by Cotron \emph{et al.} on the lacunarity modulo 2 of certain eta-quotients. Interestingly, even in the case of $p(n)$ first shown by Serre, no elementary proof is known of this bound. At the end, we propose an elegant problem on quadratic representations, whose solution would finally yield a modular form-free proof of Serre's theorem.

description: Here, the fabrication of a high aspect ratio (>440) Ge1−xSnx nanowires with super-thin (≈9 nm) diameter, much below the Bohr radius, using a simple solvothermal-like growth method under supercritical toluene conditions at a reaction temperature of 440 °C is reported. Ge1−xSnx nanowires are grown with varying amounts of Sn in Ge lattice, between 3.1 to 10.2 at%. The growth of the Ge1−xSnx alloy nanowires is achieved without any additional catalysts, and directly on current collector substrates (titanium) for application as Li-ion battery anodes. The electrochemical performance of the binder-free Ge1−xSnx nanowires as an anode material for Li-ion batteries is investigated via galvanostatic cycling and detailed analysis of differential capacity plots. The dimensions of the nanowires, and the amount of Sn in Ge, are critical to achieving a high specific capacity and capacity retention. Ge1−xSnx nanowires with the highest aspect ratios and with the lowest Sn content (3.1 at%) demonstrate exceptional capacity retention of ≈90% and 86% from the 10th to the 100th and 150th cycles respectively, while maintaining a very high specific capacity value of 1176 and 1127 mAh g−1 after the 100 and 150 cycles respectively.

description: Evidence for almost spatial flatness of the Universe has been provided from several observational probes, including the Cosmic Microwave Background (CMB) and Baryon Acoustic Oscillations (BAO) from galaxy clustering data. However, other than inflation, and in this case only in the limit of infinite time, there is no strong a priori motivation for a spatially flat Universe. Using the renormalization group (RG) technique in curved spacetime, we present in this work a theoretical motivation for spatial flatness. Starting from a general spacetime, the first step of the RG, coarse-graining, gives a Friedmann-Lemaître-Robertson-Walker (FLRW) metric with a set of parameters. Then, we study the rescaling properties of the curvature parameter, and find that zero spatial curvature of the FLRW metric is singled out as the unique scale-free, non-singular background for cosmological perturbations.

Our main strategy is to convert the series (resp.~the alternating series) to log-sine-cosine (resp.~log-sinh-cosh) integrals. Then we express all these integrals in terms of single-valued Bloch-Wigner-Ramakrishnan-Wojtkowiak-Zagier polylogarithms. The conjectures then follow from a few highly non-trivial functional equations of the polylogarithms of weight $3$ and $4$.

description: As a major component of online crime, email-based fraud is a threat that causes substantial economic losses every year. To counteract these scammers, volunteers called scam-baiters play the roles of victims, reply to scammers, and try to waste their time and attention with long and unproductive conversations. To curb email fraud and magnify the effectiveness of scam-baiting, we developed and deployed an expandable scam-baiting mailserver that can conduct scam-baiting activities automatically. We implemented three reply strategies using three different models and conducted a one-month-long experiment during which we elicited 150 messages from 130 different scammers. We compare the performance of each strategy at attracting and holding the attention of scammers, finding tradeoffs between human-written and automatically-generated response strategies. We also demonstrate that scammers can be engaged concurrently by multiple servers deploying these strategies in a second experiment, which used two server instances to contact 92 different scammers over 12 days. We release both our platform and a dataset containing conversations between our automatic scam-baiters and real human scammers, to support future work in preventing online fraud.
title: Propositional Gossip Protocols
Creators: name: Livesey, Joseph
Publisher: name: University of Liverpool Repository
Year: 2023

description: Gossip protocols are programs which can be used by a group of agents to synchronise information which is known by each. We assume each agent holds a unique piece of information which is known as a secret, with the goal of the protocol to reach a situation where all agents are experts, i.e. where each agent knows every secret. Distributed epistemic gossip protocols use epistemic formulas in the component programs for the agents. In this thesis we shall study one of the simplest classes of such protocols: propositional gossip protocols, in which the calls made by agents are determined only by the set of secrets the agent currently knows. Propositional gossip protocols are simple and quick to execute, due to their guards being evaluated in linear time, making them potentially well suited for small devices with limited memory and computational capabilities. This raises many natural questions about conditions necessary for a propositional gossip protocol to be correct, i.e. always terminated in the all-expert state. In this thesis we shall show that such a protocol can be correct only if for any two agents, at least one of them can call the other at some stage in the protocol. In other words, the underlying undirected communication graph must be complete. Furthermore, we shall show that for any such protocol with n ≥ 4 agents, at least 2n − 2 calls are required in the worst case. We continue to study the complexity of checking the correctness of such a protocol, as well as the related sub problems of termination and partial correctness, showing that these are coNP-complete problems. We move on to show how this characterization changes when fairness constraints are imposed on the call scheduler used, showing that many more protocols of different structures become viable, as the requirement of the underlying undirected communication graph to be complete is no longer necessary. We continue again to investigate the complexity of checking the correctness of these protocols with fair schedulers, showing the problem of correctness again to be coNP-complete. Finally, we shall look at the topic of simulation, in which we look at if two propositional gossip protocols can have such similarities that one may be able to replicate all call sequences from the other. This could allow for seemingly more complex protocols to be replaced with less computationally demanding protocols, whilst achieving the same results. We find that the problem of checking if a protocol may simulate another protocol is coNP-complete.

description: Modern single-particle-tracking techniques produce extensive time-series of diffusive motion in a wide variety of systems, from single-molecule motion in living-cells to movement ecology. The quest is to decipher the physical mechanisms encoded in the data and thus to better understand the probed systems. We here augment recently proposed machine-learning techniques for decoding anomalous-diffusion data to include an uncertainty estimate in addition to the predicted output. To avoid the Black-Box-Problem a Bayesian-Deep-Learning technique named Stochastic-Weight-Averaging-Gaussian is used to train models for both the classification of the diffusion model and the regression of the anomalous diffusion exponent of single-particle-trajectories. Evaluating their performance, we find that these models can achieve a well-calibrated error estimate while maintaining high prediction accuracies. In the analysis of the output uncertainty predictions we relate these to properties of the underlying diffusion models, thus providing insights into the learning process of the machine and the relevance of the output.

description: We report on the achievement of quantum degeneracy in both components of a Bose-Fermi mixture of metastable helium atoms, $^4$He* and $^3$He*. Degeneracy is achieved via Doppler cooling and forced evaporation for $^4$He*, and sympathetically cooling $^3$He* with $^4$He*. We discuss our simplified implementation, along with the high versatility of our system. This technique is able to produce a degenerate Fermi gas with a minimum reduced temperature of $T/T_F=0.14(1)$, consisting of $2.5 \times 10^4$ $^3$He* atoms. Due to the high internal energy of both isotopes single atom detection is possible, opening the possibility of a large number of experiments into Bose-Fermi mixtures.

description: We study lattice cutoff effects on the confinement-deconfinement transition and the $Z_3$ symmetry in $SU(3)$-Higgs theory in $3+1$ dimensions. The Higgs in this study is a complex triplet with vanishing bare mass and quartic coupling. The lattice cutoff is regulated by varying the number of temporal lattice sites, $N_τ$. Our results show that the nature of the confinement-deconfinement transition depends on $N_τ$. For $N_τ=2$ the transition is found to be the end point of a first-order transition and is first order for $N_τ\ge 3$. The distributions of the Polyakov loop and other observables, sensitive to the $Z_3$ symmetry, show that the strength of $Z_3$ explicit breaking decreases with $N_τ$. Up to $T\simeq 2T_c$, the free energy difference between $Z_3$ states decreases with $N_τ$, suggesting the realization of $Z_3$ symmetry in the continuum limit.

description: Noiseless linear amplification (NLA) is useful for a wide variety of quantum protocols. Here we propose a fully scalable amplifier which, for asymptotically large sizes, can perform perfect fidelity NLA on any quantum state. Given finite resources however, it is designed to perform perfect fidelity NLA on coherent states and their arbitrary superpositions. Our scheme is a generalisation of the multi-photon quantum scissor teleamplifier, which we implement using a coherent state superposition resource state. Furthermore, we prove our NLA is also a loss-tolerant relay for multi-ary phase-shift keyed coherent states. Finally, we demonstrate that our NLA is also useful for continuous-variable entanglement distillation, even with realistic experimental imperfections.

description: In the lead up to fault tolerance, the utility of quantum computing will be determined by how adequately the effects of noise can be circumvented in quantum algorithms. Hybrid quantum-classical algorithms such as the variational quantum eigensolver (VQE) have been designed for the short-term regime. However, as problems scale, VQE results are generally scrambled by noise on present-day hardware. While error mitigation techniques alleviate these issues to some extent, there is a pressing need to develop algorithmic approaches with higher robustness to noise. Here, we explore the robustness properties of the recently introduced quantum computed moments (QCM) approach to ground state energy problems, and show through an analytic example how the underlying energy estimate explicitly filters out incoherent noise. Motivated by this observation, we implement QCM for a model of quantum magnetism on IBM Quantum hardware to examine the noise-filtering effect with increasing circuit depth. We find that QCM maintains a remarkably high degree of error robustness where VQE completely fails. On instances of the quantum magnetism model up to 20 qubits for ultra-deep trial state circuits of up to ~500 CNOTs, QCM is still able to extract reasonable energy estimates. The observation is bolstered by an extensive set of experimental results. To match these results, VQE would need hardware improvement by some 2 orders of magnitude on error rates.

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: Honey bees (Apis mellifera) have a peculiar and complex reproductive biology, with queens being polyandrous and mating with several drones during one or more mating (nuptial) flights in so-called drone congregation areas. Observing the virgin queens’ and drones’ flight behaviour provides data to understand and interpret a portion of the honey bees’ complex reproductive process. Observing the behaviour of the virgin queens on the hive entrance also serves to estimate the distance from the mating place or potential drone congregation areas (DCAs) as well as to detect the presence of airborne drones in the area. In this paper, we provide a detailed description of the methodology used for observing queens’ and drones’ flights during the period of expected mating. In addition, we provide information about required equipment, tools as well as step by step description of the observation and recordkeeping process.

description: We provide a complete classification with respect to asymptotic behaviour, stability and intersections properties of radial smooth solutions to the equation $-Δ_g u=e^u$ on Riemannian model manifolds $(M,g)$ in dimension $N\ge 2$. Our assumptions include Riemannian manifolds with sectional curvatures bounded or unbounded from below. Intersection and stability properties of radial solutions are influenced by the dimension $N$ in the sense that two different kinds of behaviour occur when $2\leq N\le 9$ or $N\geq 10$, respectively. The crucial role of these dimensions in classifying solutions is well-known in Euclidean space.

description: This study aimed to evaluate the therapeutic role of erythropoietin (EPO) or myoinositol versus metformin (MET) in improving the reproductive functions and glucose tolerance in a rat model of polycystic ovary (PCOS). Oral letrozole (LTZ) was used for induction of PCOS in wester rats for 21 days, after that, MET, EPO and myoinositol were administered for the following 21 days. The LTZ-induced PCOS rats have lost their oestrous cyclicity and become fixed at the diestrus phase, developed insulin resistance, abnormal sex and gonadotrophin hormone serum levels, increased cystic follicles, decreased number of the growing follicles and very little or no corpora lutea on microscopic examination, which were reversed by the three drugs, MET, EPO and myoinositol. MET and myoinositol were mostly equally effective in improving the reproductive manifestations of the disease. However, EPO was most effective in decreasing the insulin level observed in this LTZ-induced model of PCOS.

description: The current research was aimed to evaluate the antidiabetic activity of Terminalia citrina methanolic extract (TCME) by streptozotocin-induced diabetes in male Wistar rats. TCME exhibited better in-vitro antioxidant and alpha-amylase inhibitory activity as compared to other tested extracts. TCME at 250, 500, and 750 mg/kg showed notable (p < .05) antidiabetic potential by lowering fasting blood glucose level, restoring lipid level, serum amylase, HbA1c, kidney, and liver function tests as coevidenced from histological findings of the liver, pancreas, and kidney. TCME remarkably reinstated the antioxidant enzymatic activities (CAT: 0.181 ± 0.011 IU/mg protein, SOD: 21.45 ± 1.53 IU/mg protein) and reduced lipid peroxidation level (40.60 ± 2.41 µM/mg protein) in the liver and kidney tissue of diabetic rats at 750 mg/kg dose. The acute and subacute oral toxicity study of TCME exhibited no clinical toxicity signs and mortality. Its GC-MS spectrum unveiled the existence of 10-octadecenoic acid and other compounds which might have contributed to antidiabetic potential.

description: The EU General Food Law (GFL) Regulation (EC) 178/2002 establishes the principles of risk analysis in relation to food safety and its three inter-related components: risk assessment, risk management, and risk communication. Reflecting on citizens’ perception of the risk assessment process, the new Transparency Regulation (Regulation (EU) 2019/1381) introduced new provisions on risk communication, the public disclosure of scientific data and information supporting requests for authorisations or for approvals of regulated products as well as other requests for scientific output, and the possibility for the Commission to request EFSA to commission scientific studies with the objective of verifying evidence used in its risk assessment process.
 The proposal for a legislative framework for sustainable food systems, foreseen to be published in September 2023, aims to mainstream sustainability in all present and future EU policies and legislation impacting the food system. It will establish sustainability objectives and principles that should be consistent with the provisions and objective of the GFL.
 In a dialogue with high-level experts from science, policy and society with expertise in risk assessment, management and communication, the following question was discussed:
 How will the relationship between risk assessors (RA) and risk managers (RM) evolve in view of new Food Safety scenarios in Europe?
