description: In recent years, there has been rapid growth in mobile devices such as smartphones, and a number of applications are developed specifically for the smartphone market. In particular, there are many applications that are ``free'' to the user, but depend on advertisement services for their revenue. Such applications include an advertisement module - a library provided by the advertisement service - that can collect a user's sensitive information and transmit it across the network. Users accept this business model, but in most cases the applications do not require the user's acknowledgment in order to transmit sensitive information. Therefore, such applications' behavior becomes an invasion of privacy. In our analysis of 1,188 Android applications' network traffic and permissions, 93% of the applications we analyzed connected to multiple destinations when using the network. 61% required a permission combination that included both access to sensitive information and use of networking services. These applications have the potential to leak the user's sensitive information. In an effort to enable users to control the transmission of their private information, we propose a system which, using a novel clustering method based on the HTTP packet destination and content distances, generates signatures from the clustering result and uses them to detect sensitive information leakage from Android applications. Our system does not require an Android framework modification or any special privileges. Thus users can easily introduce our system to their devices, and manage suspicious applications' network behavior in a fine grained manner. Our system accurately detected 94% of the sensitive information leakage from the applications evaluated and produced only 5% false negative results, and less than 3% false positive results.

description: Background: Several materials have been used for tissue engineering purposes, since the ideal matrix depends on the desired tissue. Silk biomaterials have come to focus due to their great mechanical properties. As untreated silkworm silk has been found to be quite immunogenic, an alternative could be spider silk. Not only does it own unique mechanical properties, its biocompatibility has been shown already in vivo. In our study, we used native spider dragline silk which is known as the strongest fibre in nature. Methodology/Principal Findings: Steel frames were originally designed and manufactured and woven with spider silk, harvesting dragline silk directly out of the animal. After sterilization, scaffolds were seeded with fibroblasts to analyse cell proliferation and adhesion. Analysis of cell morphology and actin filament alignment clearly revealed adherence. Proliferation was measured by cell count as well as determination of relative fluorescence each after 1, 2, 3, and 5 days. Cell counts for native spider silk were also compared with those for trypsin-digested spider silk. Spider silk specimens displayed less proliferation than collagen-and fibronectin-coated cover slips, enzymatic treatment reduced adhesion and proliferation rates tendentially though not significantly. Nevertheless, proliferation could be proven with high significance (p<0.01). Conclusion/Significance: Native spider silk does not require any modification to its application as a biomaterial that can rival any artificial material in terms of cell growth promoting properties. We could show adhesion mechanics on intracellular level. Additionally, proliferation kinetics were higher than in enzymatically digested controls, indicating that spider silk does not require modification. Recent findings concerning reduction of cell proliferation after exposure could not be met. As biotechnological production of the hierarchical composition of native spider silk fibres is still a challenge, our study has a pioneer role in researching cellular mechanics on native spider silk fibres.

Year: 2023

Accurate tracking the dynamics of power system plays a significant role in its reliability, resilience and security. To achieve the reliable and precise estimation results, many advanced estimation methods have been developed. However, most of them are aiming at filtering the measurement noise, while the adverse affect of partial measurement missing is rarely taken into account. To deal with this issue, a discrete distribution in the interval [0,1] is introduced to depict mechanism of partial measurement data loss that caused by the sensor failure. Then, a resilient fault tolerant extended Kalman filter (FTEKF) is designed in the recursive filter framework. Eventually, extensive simulations are carried on the different scale test systems. Numerical experimental results illustrate that the resilience and robustness of the proposed fault tolerant EKF method against partial measurement data loss.

description: Arabinoxylans (AXs) and sugar beet fibre (Fibrex) are substances which have the potential of forming cross-linked hard gels. AXs, which are classified as hemicelluloses, are the major non-starch polysaccharides in wheat bran. Sugar beet pectin is the main soluble fibre in Fibrex. The cross-linking potential of AX and Fibrex refers to the ferulic acid units, which are ester linked to the molecules´ main chain. The more ferulic acid moieties are present on the polysaccharide backbone, the more covalent cross-links may be generated. A modified AX extraction method, in which the incubation time and concentration of alkaline extracts were optimised, has been applied to extract AX from wheat bran. In addition, a modified hydrothermal extraction method has been used to extract Fibrex. The extractable AXs from wheat bran were cross-linked by the commercial laccase C (LccC) and self-produced laccases from Funalia trogii (LccFtr) and Pleurotus pulmonarius (LccPpu). Dynamic oscillation measurements on AX gels presented mechanical spectra, including storage modulus, loss modulus and loss factor of the gels. Gel samples demonstrated viscoelastic properties, which remained constant for four weeks in the gels formed with LccFtr and LccPpu. Arabinoxylan gel characteristics, including high water holding capacity, swelling ratio in saliva, and heat resistance indicated a covalently cross-linked network. Mediators (caffeic acid and ABTS) and citrus pectin did not enhance the elastic properties of the gels. Fibrex was successfully cross-linked with LccFtr to an edible gel. Analysing rheological and structural characteristics of the Fibrex gels including high water holding capacity, swelling ratio in saliva, and heat resistance) showed the viscoelastic behaviour of the gels which was attributed to the covalently cross-linked network. However, vanillin, as a mediator, and citrus pectin did not enhance covalent cross-links and elastic properties of the Fibrex gels. Rheological properties and storage stability of sweetened Fibrex gels indicated a constant storage modulus during four weeks storage. Rheological behaviour and structural properties of the Fibrex gels and AX gels were compared with gelatin gels as a reference. Using laccases as an oxidant provided gels with a solid and stable texture, comparable in firmness to traditional gelatin gels. Cross-linked gels may find uses in pharmaceutical and other industrial applications, which require a heat resistant gel that forms easily at room temperature. They also represent an ethical alternative for manufacturing vegan, halal, and kosher food.
Tidal Tail Ejection as a Signature of Type~Ia Supernovae from White Dwarf Mergers

description: The merger of two white dwarfs may be preceded by the ejection of some mass in "tidal tails", creating a circumstellar medium around the system. We consider the variety of observational signatures from this material, which depend on the lag time between the start of the merger and the ultimate explosion (assuming one occurs) of the system in a Type Ia supernova. If the time lag is fairly short, the interaction of the supernova ejecta with the tails could lead to detectable shock emission at radio, optical, and/or x-ray wavelengths. At somewhat later times, the tails produce relatively broad NaID absorption lines with velocity widths of order the white dwarf escape speed ($\sim 1000$ \kms). That none of these signatures have been detected in normal SNe Ia constrains the lag time to be either very short ($\lesssim 100$ s) or fairly long ($\gtrsim 100$ yr). If the tails have expanded and cooled over timescales $\sim 10^4$ yr, they could be observable through narrow NaID and CaII H&K absorption lines in the spectra, which are seen in some fraction of SNe Ia. Using a combination of 3D and 1D hydrodynamical codes, we model the mass-loss from tidal interactions in binary systems, and the subsequent interactions with the interstellar medium, which produce a slow-moving, dense shell of gas. We synthesize NaID line profiles by ray-casting through this shell, and show that in some circumstances tidal tails could be responsible for narrow absorptions similar to those observed.

description: Pyrichalasin H 65 belongs to the cytochalasan family of fungal natural products, and is the major phytotoxic metabolite produced by the fungal plant pathogen Magnaporthe grisea NI980. In a combined chemical and genetic approach, the biosynthesis and chemical modification of 65 were investigated in this work. Using a bipartite gene knockout strategy targeting the pyi biosynthetic gene cluster, two fundamental genes pyiS and pyiC were disrupted, resulting in the complete abolition of 65. Five tailoring genes (two P450 encoding genes, one O-AcT, one O-MeT and one OXR encoding gene) were also inactivated individually; thirteen novel cytochalasans were isolated and identified by HRMS and NMR. For the first time, we discovered that O-methyltyrosine 175 was the initial precursor of 65 from the results of pyiA KO. Six cryptic P450 genes were investigated in two pyrichalasin H P450 disruption strains by heterologous expression. HffD and CYP1 were confirmed to catalyse a C-18 hydroxylation reaction, HffG catalyses a C-7 hydroxylation reaction and CYP3 catalyses an epoxidation reaction between C-6 and C-7. Three novel epoxide cytochalasans were obtained. Four 4’- halogenated phenylalanines, together with 4’-allyl, 4’-propargyl and 4’-azido phenylalanine were fed to a ∆pyiA KO strain. This resulted in production of seven new 4’-functionalised pyrichalasins with titres around 30 - 60 mg/L. Based on seven 4’-substituted pyrichalasins generated by mutasynthesis, many functionalised pyrichalasins were created by various chemical modifications. Triazole pyrichalasins were generated by click chemistry, using azide- 258 and alkyne pyrichalasin 252 as starting materials. Bromo- pyrichalasin 256 is the substrate for the synthesis of dimeric pyrichalasin 318 via Suzuki cross coupling, while Iodo- pyrichalasin 257 is a substrate for Sonogashira coupling reactions. Moreover, dye linked pyrichalasins 308 - 316 were generated for actin visualization in cell biology. In total, eighteen novel functional pyrichalasins were synthesized.

description: Rat lungworm (Angiostrongylus cantonensis) is a zoonotic nematode that causes rat lungworm disease (angiostrongyliasis), a potentially debilitating form of meningitis, in humans worldwide. The definitive hosts for rat lungworm are primarily members of the genus Rattus, with gastropods as intermediate hosts. This parasite has emerged as an important public health concern in the United States, especially in Hawaii, where the number of human cases has increased in the last decade. Here we discuss the current knowledge of the rat lungworm, including information on the life cycle and host species, as well as updates on known infection levels. Three species of rats have been unintentionally introduced and become established in Hawaii (Rattus exulans, R. norvegicus, and R. rattus), all of which have been documented as definitive hosts of rat lungworm. Our recent findings indicate that infection levels in rats can vary by species and age. Based on these findings, we also suggest the possibility that R. rattus populations in Hawaii are capable of developing some form of acquired immunity to infection over time, which could have important management implications related to control operations. Information on rat lungworm infection levels and distribution in Hawaii is lacking, especially in rat definitive hosts, and the U.S. Department of Agriculture (USDA) National Wildlife Research Center and the University of Hawaii at Hilo are continuing efforts to help fill these gaps in knowledge.

description: Rodenticides are an essential tool in the integrated pest management of infestations of commensal rodents (Rattus norvegicus, R. rattus, and Mus musculus). With the introduction of Assembly Bill 1788, the California Ecosystems Protection Act of 2019, California is potentially facing a future with new restrictions on the use of anticoagulant rodenticides to manage commensal rodents in urban areas. Assembly Bill 1788 has been proposed specifically to protect predators from anticoagulant rodenticide poisoning and seeks to restrict the application of second-generation anticoagulant rodenticides (SGARs) for use in many urban and non-urban areas of California, USA. Exclusion and cultural practices, such as landscape management and sanitation (i.e., cleaning of property including but not limited to trash containment and removal, and drain sanitation), remain important and successful tools for managing rodent populations. However, increased exposure of wildlife to anticoagulant rodenticides has been detected California. Several animal species have been documented as having succumbed to rodenticide toxicosis. When rodents are killed by SGARs and consumed by predators, SGAR residues have been detected in the livers of predatory species. However, the effects of chronic, sublethal exposure to predators are not well understood. We discuss the current and proposed changes to rodenticide legislation in California, impacts of rodenticide to wildlife, and the potential effects of restrictions on wildlife. We discuss limitations to rodent management programs that have historically replied on the use of SGARs and the potential impacts of the proposed legislation on communities across California. We also identify research gaps that are impeding the adoption of evidence-based best management strategies for rodent control. To improve the success of commensal rodent control programs in California, more research is needed to develop effective strategies for rodent management.
title: Numbers of Human Fatalities, Injuries, and Illnesses in the United States Due to Wildlife
Creators: name: Conover, Michael R.
Publisher: name: Utah State University
Year: 2019

description: I reviewed published and unpublished papers, government reports, and websites to estimate how many people are injured or killed each year by wildlife or stricken by a zoonotic disease. Over 47,000 people annually in the United States sought medical attention after being attacked or bitten by wildlife, and approximately 8 people died annually. Most bites were by snakes, birds, rodents, and raccoons (Procyon lotor). Each year, wildlife–vehicle collisions resulted in >59,000 human injuries and >440 human fatalities, while wildlife–aircraft collisions added 16 more injuries and 10 fatalities. I also found that >68,000 people each year sought medical assistance for a zoonotic disease, and 243 of these cases were fatal. When wildlife-related casualties and fatalities are summed, >174,000 people were injured or sickened and >700 were killed by wildlife annually. These figures do not mean that wildlife populations should be reduced; they do indicate, however, that wildlife biologists have an opportunity to serve society by preventing human injuries, morbidities, and fatalities resulting from wildlife. In doing so, wildlife biologists will also be protecting the future of wildlife.

title: The Changing Role of Rodenticides and Their Alternatives in the Management of Commensal Rodents
Creators: name: Witmer, Gary W.
Publisher: name: Utah State University
Year: 2019

description: Rodents cause substantial damage and losses of foodstuffs around the world. They also transmit many diseases to humans and livestock. While various methods are used to reduce damage caused by rodents, rodenticides remain an important tool in the toolbox. However, like all tools, rodenticides have advantages and disadvantages. Several considerations are shaping the future of rodenticide use, including manufacturing and registration costs, concern about toxicity levels and nontarget animal hazards, potential hazards to children, reduced effectiveness of some formulations, and humaneness to the targeted rodents. Many of these disadvantages apply to anticoagulant rodenticides, and their use is being more restricted in numerous settings. This paper discusses rodenticide use but also alternative control methods such as traps, exclusion, habitat management, repellents, and fertility control. While there have been relatively few new developments in rodenticides and other rodent control methods in the last several decades, new formulations and active ingredients are being investigated so that these concerns can be addressed. Some of these new developments and research results are also discussed.

Here, we propose to study how well m nodes in a quantum network can establish a common reference frame from scratch, even though t of them may be arbitrarily faulty. We present a protocol that allows all correctly functioning nodes to agree on a common reference frame as long as not more than t < m/3 nodes are faulty. Our protocol furthermore has the appealing property that it allows any existing two-party protocol for reference frame agreement to be lifted to a protocol for a quantum network.

description: Effective management of rodent pests requires an ecological understanding of how they move through their environment and how those movements influence the invasion, persistence, or reinvasion of problematic colonies. Traditional methodologies used to describe rodent movement patterns, such as mark-recapture, are hindered by their time-consuming nature and limited geographic scope. As such, our understanding of how rodents interact with urban environments remains limited. Population genetic principles and tools have the capacity to greatly increase our understanding of rodent population dynamics, ecological relationships, and movements across space, but this field is often unapproachable to non-scientist pest management professionals (PMPs). In this commentary, we aim to promote collaborative and integrative rodent pest management by introducing relevant population genetic principles, providing examples of their applications in studies of urban brown rats (Rattus norvegicus), and proposing future initiatives that link scientific, private, and government entities. We reinterpret results from a 2018 study of brown rats in Vancouver, British Columbia, Canada to show how genetic relationships among individual brown rats can be used to understand the geographic distribution of genetic clusters (i.e., colonies), natural barriers to migration, and the spatial scale of dispersal. While the 2018 study originally aimed to describe patterns of population genetic structure to understand the influence of urban landscapes on rats, here we describe how these results can be exploited by PMPs to directly inform the creation of management units and decrease the likelihood of rapid post-treatment reinvasion. Further, we discuss the difficulties inherent in population genetic studies and the potential for high-quality model sites to develop generalizable strategies. Overall, we hope to expand the toolbox of PMPs, foster collaboration, and move toward more informed and sustainable management strategies.
title: Assessing Individual and Population-Level Effects of Anticoagulant Rodenticides on Wildlife
Creators: name: Quinn, Niamh
Publisher: name: Utah State University
Year: 2019

description: Anticoagulant rodenticides have been detected in many species of wildlife worldwide. However, the origins, exposure pathways, and effects of this exposure are not well understood. To accurately characterize the risks to wildlife from rodenticide use, better information is needed regarding the proportion of populations being exposed, what proportion of individuals in populations are affected, and in what ways. The relationship between anticoagulant rodenticide concentrations found in wildlife and the rate of mortality or illness have been the subjects of much research. Residue levels observed in liver and whole-body analyses vary and overlap extensively among apparently healthy asymptomatic individuals and sublethal and lethal cases. Results from laboratory studies also show there can be wide variability in lethal and sublethal effects among and within taxonomic groups. Correlating the sublethal and reproductive effects observed in laboratory studies with realistic exposure scenarios and effects in the wild is needed to improve risk assessments. For species with limited numbers or declining populations, a critical question yet to be answered is if the rodenticide exposure documented in individual animals inhibits population growth or contributes to population declines by lowering survival and reproductive success. This information is essential to the regulatory agencies that must weigh the risks and benefits of rodenticide uses and identify restrictions that are effective in reducing risks to wildlife.

description: Introduction. Potato is the fifth most important cultivated plant in the world, which delivers energy and some the nutrients. Knowing the composition of nutrients in potato tubers is a very important element of balancing a healthy diet. Potato tubers contain important levels of bioactive compounds and antioxidants, considered health-promoting components of the human diet, protecting cells and tissues from oxidative stress, and the onset of chronic diseases. Plant breeding has invested significant resources to select potato cultivars with a higher content of health-promoting compounds (Keutgen et al. 2019; Tatarowska et al. 2019). The aim of this study was to determine the effect of the cultivar on the concentration of antioxidant compounds: total carotenoids content (TC) and vitamin C (VC) and its correlation with the total antioxidant activity (TAA) in 65 potato cultivars (Solanum tuberosum).

Methods. In experiment were used 65 potato cultivars come from the work collection created within the European project Ecobreed. The field trials were carried out for three years at central part of Poland in Młochów. In these experiments low input system were applied. TC and VC were made spectrophotometrically with a UV-Vis HITACHI U-1900 spectrophotometer. TAA was evaluated by the FRAP and DPPH method.

Results. TAA of potato cultivars was evaluated by the FRAP and DPPH method. For the TC content revealed highly significant effect for year (Y), cultivar (C) and flesh colour (FC). The TC ranged from 101.5 µg/100 g DM (in cv. Kelly) to 715 µg/100 g DM (in cv. Mayan Gold).  TC values were weakly correlated in individual years and significantly higher in yellow-flashed potatoes (319.9 µg/100 g DM) than in white-flashed potatoes (175.6 µg/100 g DM). The VC content ranged from 1.0 mg/100 g FM (in cv. Bzura) to 14.8 mg/100 g FM (in cv. Twinner). The VC were higher in yellow-flashed potato (6.5 mg/100 g FM) then in white-flashed potato (5.8 mg/100 g FM). The highest TAA were observed in cvs: Colleen, Basa, Triplo, Gatsby, Ditta, Twinner, Riviera, Michalina, Damaris, Belmonda, Ambo, Savinja, 12-LHI-6. For these cultivars, the FRAP values were 0.53 TE (µmol/100 mg DM) and DPPH 0.55 TE (µmol/ 100 mg DM). The lowest TAA were observed in cvs: Owacja, Mayan Gold, Kokra, Magnolia and Kell. For them, the FRAP and DPPH values were slightly above 0.2 TE (µmol/100 mg DM).

description: We characterise the class of distributions of random stochastic matrices $X$ with the property that the products $X(n)X(n-1) ... X(1)$ of i.i.d. copies $X(k)$ of $X$ converge a.s. as $n \rightarrow \infty$ and the limit is Dirichlet distributed. This extends a result by Chamayou and Letac (1994) and is illustrated by several examples that are of interest in applications.

description: The adaptation of birds to urban environments has created direct hazards to air transportation with the potential for catastrophic incidents. Bird–aircraft collisions involving Canada geese (Branta canadensis; goose) pose greater risks to aircraft than many bird species due to their size and flocking behavior. However, information on factors driving movements of geese near airports and within aircraft arrival/departure areas for application to management are limited. To address this need, we deployed 31 neck collar-mounted global positioning system transmitters on Canada geese near Midway International Airport in Chicago, Illinois, USA during November 2015 to February 2016. We used the movement data obtained to model environmental and behavioral factors influencing the intersection of goose movements (i.e., transition from 1 location to another) with air operations areas (i.e., aircraft flight paths). Of 3,008 goose movements recorded, 821 intersected a 3-km buffer around the airport representing U.S. Federal Aviation Administration recommended distances from wildlife attractants, and 399 intersected flight paths for approaching and landing aircraft. The effects of weather (i.e., snow cover, temperature, wind speed) on the probability of geese flying varied with different air operation areas while certain habitat resources greatly increased the probability of intersection. For example, the juxtaposition of foraging (railyards with spilled grain) and loafing areas (rooftops) near the airport led to a higher probability of movements intersecting important air operations areas. The average altitude of flying geese was 29.8 m above the ground, resulting in the greatest risk of collision being within 0.5 km of the end of runways. We suggest airport goose collision mitigation management actions, such as reducing habitat resources near the airport and using focused nonlethal harassment or physical modifications, when guided by animal movement data, may further mitigate bird-strike risks.

description: We show that, for a simplicial group K,the realization of the W-construction of K is naturally homeomorphic to the universal bundle of its geometric realization. The argument involves certain recursive descriptions of the W-construction and classifying bundle and relies on the facts that the realization functor carries an action of a simplicial group to a geometric action of its realization and preserves reduced cones and colimits

description: We perform first-principles calculations to investigate the structural and electronic properties of metal-doped (10, 0) carbon nanotubes (CNTs) on a single hexagonal boron nitride (hBN) sheet in the presence of an external electric field. We consider K, Cl and Ni atoms as dopants to study the dependence of the electronic properties of the CNT on doping polarity and concentration. The electric field strength is varied from -0.2 V/Åto +0.2 V/Åto explore the effects of an external electric field on the electronic structures. Although the electronic energy bands of the hBN sheet are modified in accordance with the field strength, its electronic state in the valence or conduction band does not touch the Fermi level under the field strength considered. We conclude that the hBN as a substrate does not modify the electronic structure of the CNT, thereby leading to improvements in the device performance, compared with that of devices based on conventional substrate materials such as SiO$_2$.

description: We study the kinetics of antibaryon production and annihilation in an expanding system, assuming that it is spatially homogeneous and chemically equilibrated at the initial stage. By solving simplified rate equations for (anti)baryon abundances we study the deviations from chemical equilibrium at late stages. The calculations are done for different expansion rates and net-baryon-to-entropy ratios, covering the conditions from early Universe to heavy-ion collisions. Our analysis includes both stable (anti)baryons and resonances. We conclude that residual antibaryon abundances are very sensitive to the time scales of expansion. Our calculations naturally explain noticeable deviations of antiproton-to-pion and proton-to-pion ratios observed in nuclear collisions at the LHC energy from the thermal model predictions. We conclude that at high bombarding energies the chemical freeze-out of (anti)baryons should occur at lower temperatures as compared to mesons.

description: Aircraft bird strikes are increasing globally. Bird strikes constitute a major human health and safety risk and result in millions of dollars in economic impacts. Invasive avian species, such as the European starling (Sturnus vulgaris; starlings), have been implicated in bird strikes in North America. Because this species is highly adaptive and has been successful at establishing in new areas, such as airports, it is essential that managers better understand the potential risks and how to mitigate them. Herein we present a case study regarding a novel observation of unique starling nesting behavior that may pose a risk to airport operations and aircraft.

description: We present first results from electronic Multi-Element Remotely Linked Interferometer Network (e-MERLIN) and electronic European VLBI Network (e-EVN) observations of a small sample of ultra-steep spectrum radio sources, defined as those sources with a spectral index alpha < -1.4 between 74 MHz and 325 MHz, which are unresolved on arcsecond scales. Such sources are currently poorly understood and a number of theories as to their origin have been proposed in the literature. The new observations described here have resulted in the first detection of two of these sources at milliarcsecond scales and show that a significant fraction of ultra-steep spectrum sources may have compact structures which can only be studied at the high resolution available with very long baseline interferometry (VLBI).
