description: The Murchison Widefield Array (MWA) is an open access telescope dedicated to studying the low frequency (80$-$300 MHz) southern sky. Since beginning operations in mid 2013, the MWA has opened a new observational window in the southern hemisphere enabling many science areas. The driving science objectives of the original design were to observe 21\,cm radiation from the Epoch of Reionisation (EoR), explore the radio time domain, perform Galactic and extragalactic surveys, and monitor solar, heliospheric, and ionospheric phenomena. All together 60$+$ programs recorded 20,000 hours producing 146 papers to date. In 2016 the telescope underwent a major upgrade resulting in alternating compact and extended configurations. Other upgrades, including digital back-ends and a rapid-response triggering system, have been developed since the original array was commissioned. In this paper we review the major results from the prior operation of the MWA, and then discuss the new science paths enabled by the improved capabilities. We group these science opportunities by the four original science themes, but also include ideas for directions outside these categories.

description: Under acute hypoxia, multiple ion channels on the cell membrane are activated, causing cell swelling and eventually necrosis. LRRC8A is an indispensable protein of the volume-regulated anion channel (VRAC), which participates in swelling and the acceleration of cell necrosis. In this study, we revealed a dynamic change in the expression level of the LRRC8 family during hypoxia in 3T3-L1 cells. The disruption of LRRC8A in 3T3-L1 cells was also associated with a significant anti-necrotic phenotype upon hypoxia accompanied by the reduced expression of necrosis-related genes. In vivo, differential expression of LRRC8 family members was also identified between high-altitude pigs and their low-altitude relatives. Taken these findings together, this study demonstrates the involvement of LRRC8A in hypoxia-induced cell necrosis. Deletion of LRRC8A makes cells resistant to hypoxia-induced necrosis
Nurse Practitioner-Led Clinics in British Columbia

Publisher: name: The University of British Columbia

description: Nurse practitioners (NPs) are increasingly being recognized for their contributions to patient care and potential to improve the population's access to primary health care (Contandriopoulos et al., 2015). Ontario has been renowned for its innovation of the NP-led clinic model as a strategy for delivering primary health care to areas with high volumes of unattached patients: those who do not have a regular primary care provider (DiCenso et al., 2010). In contrast, British Columbia (BC) has lagged behind in the formation and utilization of NP-led clinics. This paper explores the evolution and utilization of NP-led clinics in Ontario, as well as the existence of similar models in BC. It identifies the major barriers to the development of NP-led clinics in BC and provides perspective as to why the NP-led clinic model has been considerably under implemented within the province. Based on this context, further research and strategies to better integrate NPs into the primary health care infrastructure of BC are suggested.

description: The structure of exotic nuclei provides valuable tests for state-of-the-art nuclear theory. In particular electromagnetic transition rates are more sensitive to aspects of nuclear forces and many-body physics than excitation energies alone. We report the first lifetime measurement of excited states in $^{21}$O, finding $τ_{1/2^+}=420^{+35}_{-32}\text{(stat)}^{+34}_{-12}\text{(sys)}$\,ps. This result together with the deduced level scheme and branching ratio of several $γ$-ray decays are compared to both phenomenological shell-model and ab initio calculations based on two- and three-nucleon forces derived from chiral effective field theory. We find that the electric quadrupole reduced transition probability of $\rm B(E2;1/2^+ \rightarrow 5/2^+_{g.s.}) = 0.71^{+0.07\ +0.02}_{-0.06\ -0.06}$~e$^2$fm$^4$, derived from the lifetime of the $1/2^+$ state, is smaller than the phenomenological result where standard effective charges are employed, suggesting the need for modifications of the latter in neutron-rich oxygen isotopes. We compare this result to both large-space and valence-space ab initio calculations, and by using multiple input interactions we explore the sensitivity of this observable to underlying details of nuclear forces.

description: Quantum Key Exchange (QKE, also known as Quantum Key Distribution or QKD) allows communicating parties to securely establish cryptographic keys. It is a well-established fact that all QKE protocols require that the parties have access to an authentic channel. Without this authenticated link, QKE is vulnerable to man-in-the-middle attacks. Overlooking this fact results in exaggerated claims and/or false expectations about the potential impact of QKE. In this paper we present a systematic comparison of QKE with traditional key establishment protocols in realistic secure communication systems.

description: The internet is a powerful digital technology tool that has revolutionized the workplace, school and family over the last decade. This paper studies the phenomenon of addiction in internet in the workplace in relation to job satisfaction and job boredom with two factors that are that directly affect employees. At the beginning we observe the theoretical background of the internet addiction but also of the other two variables of job satisfaction and boredom. Then the development of the two hypotheses that we put in the research is presented. Next we focus on the methodology of the work with the sample numbering at 110 answers, the data collection process and the measurement scales. In addition, we see the results of the research through the spss program that confirm that internet addiction has a negative significant relationship with job satisfaction and a positive significant relationship with job boredom. Finally, there are ways to deal with internet addiction, in correlation to job boredom and job satisfaction of employees, so that organizations and employers can deal with these phenomena

description: By computer simulations of systems of ellipsoids, we study the influence of the isotropic/nematic phase transition on the direct correlation functions (DCF) in anisotropic fluids. The DCF is determined from the pair distribution function by solving the full Ornstein-Zernike equation, without any approximations. Using a suitable molecular-fixed reference frame, we can distinguish between two qualitatively different contributions to the DCF: One which preserves rotational invariance, and one which breaks it and vanishes in the isotropic phase. We find that the symmetry preserving contribution is barely affected by the phase transition. However, symmetry breaking contributions emerge in the nematic phase and may become quite substantial. Thus the DCF in a nematic fluid is not rotationally invariant. In the isotropic fluid, the DCF is in good agreement with the prediction of the Percus-Yevick theory.

description: High contact resistance is one of the primary concerns for electronic device applications of two-dimensional (2D) layered semiconductors. Here, we explore the enhanced carrier transport through metal-semiconductor interfaces in WS2 field effect transistors (FETs) by introducing a typical transition metal, Cu, with two different doping strategies: (i) a "generalized" Cu doping by using randomly distributed Cu atoms along the channel and (ii) a "localized" Cu doping by adapting an ultrathin Cu layer at the metal-semiconductor interface. Compared to the pristine WS2 FETs, both the generalized Cu atomic dopant and localized Cu contact decoration can provide a Schottky-to-Ohmic contact transition owing to the reduced contact resistances by 1 - 3 orders of magnitude, and consequently elevate electron mobilities by 5 - 7 times higher. Our work demonstrates that the introduction of transition metal can be an efficient and reliable technique to enhance the carrier transport and device performance in 2D TMD FETs.

Time-dependent low latitude core flow and geomagnetic field acceleration pulses

description: We present a new model of time-dependent flow at low latitudes in the Earth's core between 2000 and 2018, derived from magnetic field measurements made on board the {\it Swarm} and CHAMP satellites and at ground magnetic observatories. The model, called {\it CoreFlo-LL.1}, consists of a steady background flow without imposed symmetry plus a time-dependent flow that is dominated by geostrophic and quasi-geostrophic components but also allows weak departures from equatorial symmetry. We find that the equatorial region beneath the core-mantle boundary is a place of vigorous, localised, fluid motions; time-dependent flow focused at low latitudes close to the core surface is able to reproduce rapid field variations observed at non-polar latitudes at and above Earth's surface. Magnetic field acceleration pulses are produced by alternating bursts of non-zonal azimuthal flow acceleration in this region. Such acceleration sign changes can occur within a year or less, and when the structures involved are of large spatial scale they can give rise to geomagnetic jerks at the Earth's surface.

description: To sustainably cope with the continuous depletion of fishery stock, the adaptation among small-scale fishers is imperative. This study was conducted to analyze the effects of small-scale fishers’ risk preference on their choice of adaptation strategies concerning fishery stock depletion. A multiple price list experiment was conducted to elicit the risk preference of the small-scale fishers. The results showed that small-scale fishers in Guimaras were slightly risk-averse. Meanwhile, various adaptation strategies were employed by the small-scale fishers as a response to fishery stock depletion. Based on the multivariate probit regression results, more risk-averse small-scale fishers were more likely to reduce fishing effort but less likely to modify fishing gear. These results highlight the need for planned intervention and streamlining of adaptation mechanisms in fishery governance to address fishery stock depletion, so the small-scale fishers’ livelihoods are not compromised in the process.
Complications in the interpretation of the charge asymmetry dependent $π$ flow for the chiral magnetic wave

description: The charge asymmetry ($A_{\rm ch}$) dependence of the $π^{-}$ and $π^{+}$ elliptic flow difference, $Δv_{2}(A_{\rm ch})$, has been regarded as a sensitive observable for the possible chiral magnetic wave (CMW) in relativistic heavy ion collisions. In this work, we first demonstrate that, due to non-flow backgrounds, the flow measurements by the Q-cumulant method using all charged particles as reference introduce a trivial linear term to $Δv_{2}(A_{\rm ch})$. The trivial slope can be negative in the triangle flow difference $Δv_{3}(A_{\rm ch})$ if the non-flow is dominated by back-to-back pairs. After eliminating the trivial term, we find that the non-flow between like-sign pairs gives rise to an additional positive slope to $Δv_{2}(A_{\rm ch})$ because of the larger dilution effect to $π^{+}$ ($π^{-}$) at positive (negative) $A_{\rm ch}$. We further find that the competition between different $π$ sources can introduce another non-trivial linear-$A_{\rm ch}$ term due to their different multiplicity fluctuations and anisotropic flows. We then study the effect of neutral cluster (resonance) decays as a mechanism for local charge conservation on the slope parameter of $Δv_{2}(A_{\rm ch})$. We find that the slope parameter is sensitive to the kinematics of those neutral clusters. Light resonances give positive slopes while heavy resonances give negative slopes. Local charge conservation from continuum cluster mass distribution can give a positive slope parameter comparable to experimental data. Our studies indicate that many non-CMW physics mechanisms can give rise to a $A_{\rm ch}$-dependent $Δv_{2}(A_{\rm ch})$ and the interpretation of $Δv_{2}(A_{\rm ch})$ in terms of the CMW is delicate.

description: Combining precise B,V photoelectric photometry and radial velocities, we have been able to derive a firm orbital solution and accurate physical parameters for the newly discovered eclipsing binary HD 23642 in the Pleiades open cluster. The resulting distance to the binary, and therefore to the cluster, is 132 +/- 2 pc. This closely confirms the distance modulus obtained by classical main sequence fitting methods (m-M = 5.60 or 132 pc), moving cluster techniques and the astrometric orbit of Atlas. This is the first time the distance to a member of the Pleiades is derived by orbital solution of a double-lined eclipsing binary, and it is intended to contribute to the ongoing discussion about the discordant Hipparcos distance to the cluster.

description: The study identified the likely indicators of the social adaptive capacities of communities of Barangay Patitinan, Sagñay, Camarines Sur, a known landslide prone barangay. Results from a previous survey, focus group discussions, and key informant interviews were used to assess and ascertain these indicators. All likely indicators were present in Barangay Patitinan. Though all indicators identified were present in the communities of Barangay Patitinan, there are still aspects of these indicators that can be improved further. Thus, the study recommends bioengineering approach that not only leads to slope stabilization but also promotes biodiversity, diversification of income opportunities, strengthening community’s engagement in development planning through collaboration between the Barangay Disaster Risk Reduction and Management Council and the Barangay’s Environment Committee, development of a participatory comprehensive plan, development of activities that promote cooperation and cohesion, and finally, the conduct of other related researches.

description: This paper addresses a multi-pursuer single-evader pursuit-evasion game where the free-moving evader moves faster than the pursuers. Most of the existing works impose constraints on the faster evader such as limited moving area and moving direction. When the faster evader is allowed to move freely without any constraint, the main issues are how to form an encirclement to trap the evader into the capture domain, how to balance between forming an encirclement and approaching the faster evader, and what conditions make the capture possible. In this paper, a distributed pursuit algorithm is proposed to enable pursuers to form an encirclement and approach the faster evader. An algorithm that balances between forming an encirclement and approaching the faster evader is proposed. Moreover, sufficient capture conditions are derived based on the initial spatial distribution and the speed ratios of the pursuers and the evader. Simulation and experimental results on ground robots validate the effectiveness and practicability of the proposed method.

The structures were prepared by inserting a thin Al$_{0.3}$Ga$_{0.7}$As barrier into the GaAs buffer layer of a standard modulation-doped GaAs/Al$_{0.3}$Ga$_{0.7}$As heterostructure. The resulting double-well system consists of a nearly rectangular well and of a triangular well coupled by tunneling through the thin barrier. With a proper choice of the barrier parameters one can control the occupancy of the two wells and of the two lowest (bonding and antibonding) subbands. The electron properties can be further influenced by applying front- or back-gate voltage.

We benchmark the impurity solver against exact diagonalization, and apply the method to study the infinite $U$ Hubbard model, the periodic Anderson model and the $pd$ model. This simple and numerically efficient approach yields the spectra expected for strongly correlated materials, with a quasiparticle peak and a Hubbard band. It works in a large range of parameters, and therefore can be used for the exploration of real materials using LDA+DMFT.

description: We present results from a theoretical and experimental study of spin-splitting in small open lateral quantum dots (i.e. in the regime when the dot is connected to the reservoirs via leads that support one or more propagating modes). We demonstrate that the magnetoconductance shows a pronounced splitting of the conductance peaks (or dips) which persists over a wide range of magnetic fields (from zero field to the edge-state regime) and is virtually independent of magnetic field. A numerical analysis of the conductance and the dot eigenspectrum indicates that this feature is related to a lifting of the spin degeneracy in the corresponding closed dot associated with the interaction between electrons of opposite spin.

description: The isovector and isoscalar $ND$ $s$-wave scattering lengths are extracted by fitting to the LHCb data of the $pD^0$ invariant-mass distribution in the decay $Λ_b\rightarrowπ^-pD^0$, making use of the cusp effect at the $nD^+$ threshold. The analysis is based on a coupled-channel nonrelativistic effective field theory. We find that the real part of the isovector $ND$ scattering length is unnaturally large due to the existence of a near-threshold state with a mass around 2.8 GeV. The state is consistent with the $Σ_c(2800)^+$ resonance observed at Belle. Our results suggest that it couples strongly to the $ND$ channel in an $s$-wave, and that its quantum numbers are $J^P=1/2^-$. The strong cusp behavior at the $nD^+$ threshold can be verified using updated LHCb data.

description: We provide evidence that proton irradiation of energy 2.25 MeV on highly-oriented pyrolytic graphite samples triggers ferro- or ferrimagnetism. Measurements performed with a superconducting quantum interferometer device (SQUID) and magnetic force microscopy (MFM) reveal that the magnetic ordering is stable at room temperature.

description: Η εργασία θα πραγματεύεται το ζήτημα της φωνολογικής αναπαράστασης του νεοελληνικού ημιφώνου j και της σχέσης του με το υψηλό φωνήεν i. Στα πλαίσιά της θα γίνει μια στατιστική ανάλυση χρησιμοποιώντας τον αλγόριθμο Random Forest. Με τη χρήση του αλγόριθμου αυτού θα εξεταστούν οι ποικίλες ημιφωνικές πραγματώσεις [j, ʝ, ç, c, ɟ, ʎ, ɲ] (στο εξής [J]) ανάλογα με το περιβάλλον της φωνηεντικής πραγμάτωσης [i]. Επίσης προτείνεται μια ανάλυση στο πλαίσιο της Διαβαθμισμένης Αρμονικής Γραμματικής (Smolensky & Goldrick, 2016). Συγκεκριμένα, υποστηρίζεται ότι το φωνολογικό σύστημα της Ελληνικής περιλαμβάνει δύο διακριτά φωνήματα /j/ και /i/, τα οποία διαφέρουν ως προς το διακριτικό χαρακτηριστικό. Βασικό σημείο της ανάλυσης αποτελεί η υπόθεση ότι το συγκεκριμένο χαρακτηριστικό δεν είναι δυαδικό, αλλά διαθέτει στην υποκείμενη δομή ένα διαβαθμισμένο επίπεδο ενέργειας, το οποίο κυμαίνεται μεταξύ των τιμών 0 και 1. Στην ανάλυση θα εξεταστούν οι περιπτώσεις συστηματικής εναλλαγής μεταξύ των δύο πραγματώσεων στο πλαίσιο κλιτικών παραδειγμάτων. Τα παραδείγματα αυτά αφορούν τα ουδέτερα ουσιαστικά που έχουν [i] στην λήγουσά τους και η εναλλαγή των στοιχείων /i/ που υπάρχει στην ονομαστική ενικού με το /j/ της γενικής ενικού και της ονομαστικής πληθυντικού. Τέλος θα εξεταστεί και η περίπτωση των τοπωνυμίων που έχουν μεν [i] στην λήγουσά τους αλλά δεν τηρούν το συγκεκριμένο κλιτικό παράδειγμα
description: This MA thesis is about the issue of the phonological representation of the Greek glide j and its relationship with the vowel i. The thesis includes a probabilistic analysis using the Random Forest Algorithm. With the use of this algorithm, we are going to check the various glide alterations [j, ʝ, ç, c, ɟ, ʎ, ɲ] depending on the environment of the realization of the vowel [i]. Also, we suggest a new analysis following the Gradient Harmonic Grammar theory (Smolensky & Goldrick, 2016). More specifically we suggest that the Greek phonological system includes two discrete phonemes /j/ and /i/ which differ in their distinctive features. A key point of this analysis is that this feature is not binary but has a Gradient activity level which is between 0 and 1. In the analysis we will examine cases of systematic alterations of the two realizations. We will use examples taken from neutral nouns that include [i] in their ultimate syllable and the alteration between /i/ in the singular nominative case and the /j/ of the singular genitive and the plural nominative cases. We will conclude with certain examples of toponyms

description: We present a Monte Carlo approach to incorporating the effect of thermal fluctuations in field theories of polymeric fluids. This method is applied to a field-theoretic model of a ternary blend of AB diblock copolymers with A and B homopolymers. We find a shift in the line of order-disorder transitions from their mean-field values, as well as strong signatures of the existence of a bicontinuous microemulsion phase in the vicinity of the mean-field Lifshitz critical point. This is in qualitative agreement with a recent series of experiments conducted with various three-dimensional realizations of this model system. Further, we also compare our results and the performance of the presently proposed simulation method to that of an alternative method involving the integration of complex Langevin dynamical equations.

Toward the full short-time statistics of an active Brownian particle on the plane

description: We study the position distribution of a single active Brownian particle (ABP) on the plane. We show that this distribution has a compact support, the boundary of which is an expanding circle. We focus on a short-time regime and employ the optimal fluctuation method (OFM) to study large deviations of the particle position coordinates $x$ and $y$. We determine the optimal paths of the ABP, conditioned on reaching specified values of $x$ and $y$, and the large deviation functions of the marginal distributions of $x$, and of $y$. These marginal distributions match continuously with "near tails" of the $x$ and $y$ distributions of typical fluctuations, studied earlier. We also calculate the large deviation function of the joint $x$ and $y$ distribution $P(x,y,t)$ in a vicinity of a special "zero-noise" point, and show that $\ln P(x,y,t)$ has a nontrivial self-similar structure as a function of $x$, $y$ and $t$. The joint distribution vanishes extremely fast at the expanding circle, exhibiting an essential singularity there. This singularity is inherited by the marginal $x$- and $y$-distributions. We argue that this fingerprint of the short-time dynamics remains there at all times.

description: As the world’s largest importer of agricultural commodities, China’s agricultural policies have significant implications for the world agricultural market. For the first time, we develop an aggregate structural econometric model of China’s soybean market with linkage to the rest of the world to analyze the worldwide impacts of China’s soybean price support policies from 2008 to 2016. We investigate the impacts of China’s policies on the variability of their domestic and world prices, and adopt a Monte Carlo simulation to evaluate the distributional and aggregate welfare effects. Results indicate that (a) China’s soybean price support policies play an effective role in stabilizing their domestic price, while its increasing imports absorb world production surplus and reduce world price swings; (b) China’s producers gain at the expense of consumers and budgetary costs, and the net welfare change in their domestic market is negative; (c) Soybean exporting countries experience considerable welfare gains, and the world net welfare change is positive. Our findings provide new insights for future trade negotiations and agricultural market reforms in developing countries.

description: The study evaluated the economic appraisal of inert atmosphere silo used for wheat storage in Ilorin. NSPRI has developed inert atmosphere silo for storage of grains and this has successfully stored wheat among other grains for four year without quality deterioration, but the targeted stakeholders in grains postharvest value chain have not'been able to adopt the technology. Their fear is not far fetch from the uncertainty of how cost effective the technology will be. The study was conducted to appraise the economics of the technology for storage of wheat and other grains. Budgeting and profitability analytical techniques were used to analyze the data generated by the study. The study revealed that storage of wheat using inert atmosphere silo is highly profitable with a gross margin of H 5, 182,250.00. Lastly, Return per N aira from wheat grains storage using the silo is 0.44. The return on the investment almost hits 50 % of the financial commitment to the investment made on the Technology (Silo) for grains storage. To reduce postharvest grain losses and increase food security in the country, governments at all levels, Farmers' Association Stakeholders and grains merchants should work with NSPRI on the adoption of the technology.

description: In this article we study extensions of Z_2-graded L_infinity algebras on a vector space of two even and one odd dimension. In particular, we determine all extensions of a super Lie algebra as an L_infinity algebra. Our convention on the parities is the opposite of the usual one, because we define our structures on the symmetric coalgebra of the parity reversion of a space.

description: A series of solar energetic particle (SEP) events were observed at Parker Solar Probe (PSP) by the Integrated Science Investigation of the Sun (\ISOIS) during the period from April 18, 2019 through April 24, 2019. The PSP spacecraft was located near 0.48 au from the Sun on Parker spiral field lines that projected out to 1 au within $\sim 25^\circ$ of near Earth spacecraft. These SEP events, though small compared to historically large SEP events, were amongst the largest observed thus far in the PSP mission and provide critical information about the space environment inside 1 au during SEP events. During this period the Sun released multiple coronal mass ejections (CMEs). One of these CMEs observed was initiated on April 20, 2019 at 01:25 UTC, and the interplanetary CME (ICME) propagated out and passed over the PSP spacecraft. Observations by the Electromagnetic Fields Investigation (FIELDS) show that the magnetic field structure was mostly radial throughout the passage of the compression region and the plasma that followed, indicating that PSP did not directly observe a flux rope internal to the ICME, consistent with the location of PSP on the ICME flank. Analysis using relativistic electrons observed near Earth by the Electron, Proton and Alpha Monitor (EPAM) on the Advanced Composition Explorer (ACE) demonstrates the presence of electron seed populations (40--300 keV) during the events observed. The energy spectrum of the \ISOIS~ observed proton seed population below 1 MeV is close to the limit of possible stationary state plasma distributions out of equilibrium. \ISOIS~ observations reveal the \revise{enhancement} of seed populations during the passage of the ICME, which \revise{likely indicates a key part} of the pre-acceleration process that occurs close to the Sun.
