description: The paper deals with the three-dimensional Dirichlet boundary value problem (BVP) for a second order strongly elliptic self-adjoint system of partial differential equations in the divergence form with variable coefficients and develops the integral potential method based on a localized parametrix. Using Green's representation formula and properties of the localized layer and volume potentials, we reduce the Dirichlet BVP to a system of localized boundary-domain integral equations (LBDIEs). The equivalence between the Dirichlet BVP and the corresponding LBDIE system is studied. We establish that the obtained localized boundary-domain integral operator belongs to the Boutet de Monvel algebra. With the help of the Wiener-Hopf factorization method we investigate corresponding Fredholm properties and prove invertibility of the localized operator in appropriate Sobolev (Bessel potential) spaces.

description: We have identified epitaxially grown elemental Te as a capping material that is suited to protect the topological surface states of intrinsically insulating Bi$_2$Te$_3$. By using angle-resolved photoemission, we were able to show that the Te overlayer leaves the dispersive bands of the surface states intact and that it does not alter the chemical potential of the Bi$_2$Te$_3$ thin film. From in-situ four-point contact measurements, we observed that the conductivity of the capped film is still mainly determined by the metallic surface states and that the contribution of the capping layer is minor. Moreover, the Te overlayer can be annealed away in vacuum to produce a clean Bi$_2$Te$_3$ surface in its pristine state even after the exposure of the capped film to air. Our findings will facilitate well-defined and reliable ex-situ experiments on the properties of Bi$_2$Te$_3$ surface states with nontrivial topology.

description: This is a scanned copy of a document, including a map and photographs, of a trend assessment of Protea nitida and Protea arborea in Jonkershoek, Jakkalsvlei, site 3318DD1/5. The Jonkershoek Forestry Research Center (part of the former South African Forestry Research Institute) was established in 1935 at Jonkershoek, near Stellenbosch, under the directorship of Dr C. L. Wicht. The initial aim was to determine how forestry activities in state plantations would affect climate, water conservation and erosion, and was later expanded to include studies of fynbos ecology, fire and alien species. Studies from the 1930s to the early 1990s saw the accumulation of a large amount of data dealing with fire experiments, detailed vegetation plot surveys, rare plant surveys and ecological studies, hydrological studies and the development of management plans for catchments around the Western Cape. SAEON now houses the archive of data collected by the Jonkershoek Forestry Research Center, which was originally held by the Council for Scientific and Industrial Research (CSIR).

description: Large-scale biomass plantations (BPs) are often considered a feasible and safe climate engineering proposal for extracting carbon from the atmosphere and, thereby, reducing global mean temperatures. However, the capacity of such terrestrial carbon dioxide removal (tCDR) strategies and their larger Earth system impacts remain to be comprehensively studied—even more so under higher carbon emissions and progressing climate change. Here, we use a spatially explicit process-based biosphere model to systematically quantify the potentials and trade-offs of a range of BP scenarios dedicated to tCDR, representing different assumptions about which areas are convertible. Based on a moderateCO2 concentration pathway resulting in a global mean warming of 2.5° Cabove preindustrial level by the end of this century—similar to the Representative Concentration Pathway (RCP) 4.5—we assume tCDR to be implemented when a warming of 1.5 °Cis reached in year 2038. Our results show that BPs can slow down the progression of increasing cumulative carbon in the atmosphere only sufficiently if emissions are reduced simultaneously like in the underlying RCP4.5 trajectory. The potential of tCDR to balance additional, unabated emissions leading towards a business-as-usual pathway alike RCP8.5 is therefore very limited. Furthermore, in the required largescale applications, these plantations would induce significant trade-offs with food production and biodiversity and exert impacts on forest extent, biogeochemical cycles and biogeophysical properties.

description: The electronic structure of Pb$_{1-x}$Sn$_{x}$Te is studied by using the relativistic Korringa-Kohn-Rostoker Green function method in the framework of density functional theory. For all concentrations $x$, Pb$_{1-x}$Sn$_{x}$Te is a direct semiconductor with a narrow band gap. In contrast to pure lead telluride, tin telluride shows an inverted band characteristic close to the Fermi energy. It will be shown that this particular property can be tuned, first, by alloying PbTe and SnTe and, second, by applying hydrostatic pressure or uniaxial strain. Furthermore, the magnitude of strain needed to switch between the regular and inverted band gap can be tuned by the alloy composition. Thus, there is range of potential usage of Pb$_{1-x}$Sn$_{x}$Te for spintronic applications.

description: The target study explores whether evaluations of the same piece of music differ under two distinct listening conditions: listening to a piece described either as an improvisation or as a preexisting composition. Participants (N = 16) in the two conditions listened to the same musical piece and provided verbal evaluative judgements. The author used a grounded theory approach to analyze listeners’ responses, reporting different listening experiences in the two groups. The findings provide unique insights to enable a greater understanding of the nature of the aesthetics of improvisation. In this commentary, I first discuss the strengths of the article, followed by methodological considerations and suggestions for future research. I then present a short literature review and discussion of what I consider the most relevant topic in relation to this study, namely, the effects of contextual information on subjective evaluations.

description: BACKGROUND: Infectious Diseases Society of America guidelines recommend that key antimicrobial stewardship program (ASP) personnel include an infectious disease (ID) physician leader and dedicated ID-trained clinical pharmacist. Limited resources prompted development of an alternative model by using ID physicians and service-based clinical pharmacists at a pediatric hospital. The aim of this study was to analyze the effectiveness and impact of this alternative ASP model.

METHODS: The collaborative ASP model incorporated key strategies of education, antimicrobial restriction, day 3 audits, and practice guidelines. High-use and/or high-cost antimicrobial agents were chosen with audits targeting vancomycin, caspofungin, and meropenem. The electronic medical record was used to identify patients requiring day 3 audits and to communicate ASP recommendations. Segmented regression analyses were used to analyze quarterly antimicrobial agent prescription data for the institution and selected services over time.

RESULTS: Initiation of ASP and day 3 auditing was associated with blunting of a preexisting increasing trend for caspofungin drug starts and use and a significant downward trend for vancomycin drug starts (relative change -12%) and use (-25%), with the largest reduction in critical care areas. Although meropenem use was already low due to preexisting requirements for preauthorization, a decline in drug use (-31%, P = .021) and a nonsignificant decline in drug starts (-21%, P = .067) were noted. A 3-month review of acceptance of ASP recommendations found rates of 90%, 93%, and 100% for vancomycin, caspofungin, and meropenem, respectively.

CONCLUSIONS: This nontraditional ASP model significantly reduced targeted drug usage demonstrating acceptance of integration of service-based clinical pharmacists and ID consultants.
The effects of social media use on older adults' mental health and wellbeing: a systematic review and a longitudinal study
Creators: name: Lei, Xiaojing
Publisher: name: Macquarie University
Year: 2023

description: This thesis comprised two components, a systematic review and a longitudinal survey study. The systematic review aimed to synthesise the effects of social media use on mental health and wellbeing in older adults by systematically searching three electronic databases PsycINFO, PubMed and CINAHL in November 2021. Forty-four papers met inclusion criteria including 20 cross-sectional studies, five observational longitudinal studies, nine interventional studies, three mixed-methods studies and seven qualitative studies. While associations between social media use and positive mental health and wellbeing outcomes are generally reported in cross-sectional studies, the impact of social media use over time from longitudinal studies was mixed and inconclusive. More research is needed to understand the impacts of social media use on older adults' mental health and wellbeing. The longitudinal survey study aimed to investigate the characteristics of the use and effects of social media on older adults' depression, anxiety, and loneliness over time. The online survey was administered twice (three months apart). One hundred and twenty-one participants (Mage = 73, SD = 7, range = 60 to 92, 68% female) completed the survey at time one and 63 (Mage = 72, SD = 7, range = 60 to 86, 62% female) of these completed the survey at time two. The survey presented questions on demographics, social network size and quality, social interaction anxiety, patterns of social internet use, loneliness, depression and anxiety. The overall findings were that social media use led to increased loneliness over time over and above control variables, but did not uniquely impact depression or anxiety. Post-hoc tests suggested that sending and receiving photos may be particularly relevant for future loneliness. More research is needed to understand the impacts of social media use on mental health and wellbeing, and the causal factors that drive this effect.

description: Rewriting logic is a natural and expressive framework for the specification of concurrent systems and logics. The Maude specification language provides an implementation of this formalism that allows executing, verifying, and analyzing the represented systems. These specifications declare their objects by means of terms and equations, and provide rewriting rules to represent potentially non-deterministic local transformations on the state. Sometimes a controlled application of these rules is required to reduce non-determinism, to capture global, goal-oriented or efficiency concerns, or to select specific executions for their analysis. That is what we call a strategy. In order to express them, respecting the separation of concerns principle, a Maude strategy language was proposed and developed. The first implementation of the strategy language was done in Maude itself using its reflective features. After ample experimentation, some more features have been added and, for greater efficiency, the strategy language has been implemented in C++ as an integral part of the Maude system.
 This paper describes the Maude strategy language along with its semantics, its implementation decisions, and several application examples from various fields.

The HOMO-LUMO gap, the Hirshfeld charges, and the equilibrium geometrical structures exhibit keen variations depending on the species of the attached amino acid. The GO-amino acid system appears to be a good candidate as a biosensor.
Halo-independent tests of dark matter annual modulation signals

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: I derive new halo-independent lower bounds on the product of the dark matter-nucleon scattering cross section and the local dark matter density that are valid for annual modulations of dark matter direct detection signals. They are obtained by making use of halo-independent bounds based on an expansion of the rate on the Earth's velocity that were derived in previous works. In combination with astrophysical measurements of the local energy density, an observed annual modulation implies a lower bound on the cross section that is independent of the velocity distribution and that must be fulfilled by any particle physics model. In order to illustrate the power of the bounds we apply them to DAMA/LIBRA data and obtain quite strong results when compared to the standard halo model predictions. We also extend the bounds to the case of multi-target detectors.

description: We investigate the coupling of an ensemble of phosphorus donors in an isotopically purified $^{28}$Si host lattice interacting with a superconducting coplanar waveguide resonator. The microwave transmission spectrum of the resonator shows a normal mode splitting characteristic for high cooperativity. The evaluated collective coupling strength $g_{\mathrm{eff}}$ is of the same order as the loss rate of the spin system $γ$, indicating the onset of strong coupling. We develop a statistical model to describe the influence of temperature on the coupling strength from $50\,\mathrm{mK}$ to $3.5\,\mathrm{K}$ and find a scaling of the coupling strength with the square root of the number of thermally polarized spins.

description: We study long-time dynamics of a bosonic system after suddenly switching on repulsive delta-like interactions. As initial states, we consider two experimentally relevant configurations: a rotating BEC and two counter-propagating BECs with opposite momentum, both on a ring. In the first case, the rapidity distribution function for the stationary state is derived analytically and it is given by the distribution obtained for the same quench starting from a BEC, shifted by the momentum of each boson. In the second case, the rapidity distribution function is obtained numerically for generic values of repulsive interaction and initial momentum. The significant differences for the case of large versus small quenches are discussed.

Les revues de mortalité et de morbidité (RMM) et les comités de retour d’expérience (Crex) sont deux méthodes permettant de gérer la sécurité des patients dans les équipes soignantes. L’objectif de cette étude était de comparer les perceptions des professionnels de santé utilisant conjointement l’une et l’autre de ces deux méthodes et de déterminer l’impact de cette double utilisation. Méthodes. Nous avons réalisé une étude qualitative basée sur des entretiens semi-directifs auprès de 14 professionnels de santé exerçant dans des services hospitaliers disposant de RMM et de Crex. Résultats. Les deux outils étaient appréciés par les soignants et perçus comme complémentaires. Les Crex étaient perçus comme favorisant la pluridisciplinarité et encourageant la pratique de l’analyse systémique des événements indésirables, permettant d’améliorer l’organisation des équipes. Les RMM, plutôt tournées vers les médecins et à la méthodologie moins standardisée, semblaient plus centrées sur l’évaluation des pratiques professionnelles, encourageant la formation continue des professionnels. Il y avait peu de transfert méthodologique d’un outil à l’autre. Enfin, les soignants ont décrit des faiblesses similaires pour les deux outils (manque de temps, de valorisation et de communication autour des outils et des actions menées). Conclusions. Les Crex et les RMM sont deux outils complémentaires concourant à l’amélioration de l’organisation et des pratiques des équipes soignantes. Ces deux outils connaissent cependant des limites communes, inhérentes au manque de temps des professionnels et aux leviers d’action insuffisants dont disposent les équipes participant à ces dispositifs.

description: We perform a search for dormant comets, asteroidal objects of cometary origin, in the near-Earth asteroid (NEA) population based on dynamical and physical considerations. Our study is based on albedos derived within the ExploreNEOs program and is extended by adding data from NEOWISE and the Akari asteroid catalog. We use a statistical approach to identify asteroids on orbits that resemble those of short-period near-Earth comets using the Tisserand parameter with respect to Jupiter, the aphelion distance, and the minimum orbital intersection distance with respect to Jupiter. From the sample of NEAs on comet-like orbits, we select those with a geometric albedo $p_V \leq 0.064$ as dormant comet candidates, and find that only $\sim$50% of NEAs on comet-like orbits also have comet-like albedos. We identify a total of 23 NEAs from our sample that are likely to be dormant short-period near-Earth comets and, based on a de-biasing procedure applied to the cryogenic NEOWISE survey, estimate both magnitude-limited and size-limited fractions of the NEA population that are dormant short-period comets. We find that 0.3-3.3% of the NEA population with $H \leq 21$, and $9^{+2}_{-5}$% of the population with diameters $d \geq 1$ km, are dormant short-period near-Earth comets.

description: Extreme weather events are expected to increase. The paper provides a concise overview of climate change as well as issues pertaining to extreme weather events. Several indicators used to quantify climate variability, to assess countries’ vulnerability to climate change and extreme weather negative impacts are presented. In Asia rice assumes strategic relevance, thus accounting most of the world production and consumption. This paper aims at expanding the above statement and at investigating the potential effects of weather events on rice supply using a multiple regression analysis. Given its vulnerability to climate change and its limited ability to cope with it, Asia is expected to be severely affected by the adverse impacts of extreme weather conditions, where food security still represents a major concern.

description: The survey on the determination of the production costs of the farm ornamental plants always raises a widespread interest. The data and information related to the production costs are indeed instrumental to the identification of the sustainability of sustained competitive advantages, especially for those products for which market competition is so high that they need to innovate continuously especially in terms of technology. A survey, conducted in Sicily, proposes a structured study of the cost of the the product through the method called by “center of cost” or “cost center”. The study refers to the functional criterion-causal that allows a recognition of only product costs incurred to achieve it, with reference to the lemon in pots for ornamental purposes.

description: Pediatric Life Support (PLS) courses and instructional programs are educational tools developed to teach resuscitation and stabilization of children who are critically ill or injured. A number of PLS courses have been developed by national professional organizations for different health care providers (eg, pediatricians, emergency physicians, other physicians, prehospital professionals, pediatric and emergency advanced practice nurses, physician assistants). PLS courses and programs have attempted to clarify and standardize assessment and treatment approaches for clinical practice in emergency, trauma, and critical care. Although the effectiveness of PLS education has not yet been scientifically validated, the courses and programs have significantly expanded pediatric resuscitation training throughout the United States and internationally. Variability in terminology and in assessment components used in education and training among PLS courses has the potential to create confusion among target groups and in how experts train educators and learners to teach and practice pediatric emergency, trauma, and critical care. It is critical that all educators use standard terminology and patient assessment to address potential or actual conflicts regarding patient evaluation and treatment. This article provides a consensus of several organizations as to the proper order and terminology for pediatric patient assessment. The Supplemental Information provides definitions for terms and nomenclature used in pediatric resuscitation and life support courses.

The construction makes use of subsidiary $(N-1)$-particle states which are propagated in time in addition to the true $N$-particle state, but does not involve spontaneous breaking of the $U(1)$ symmetry associated with particle number conservation. Provided the flow in Fock space possesses a property which we call maximum stiffness, or $t$-coherence, the candidate amplitude actually satisfies the time-dependent Gross-Pitaevskii equation, and then serves as macroscopic wave function of the forced $N$-particle system. The general procedure is illustrated in detail by numerical calculations performed for the model of a driven bosonic Josephson junction, which allows one to keep track of all contributions which usually are subject to uncontrolled assumptions. These calculations indicate that macroscopic wave functions can persist even under conditions of strong forcing, but are rapidly destroyed upon entering a regime of chaotic dynamics. Our results provide a foundation for future attempts to manipulate, and actively control, macroscopic wave functions by means of purposefully designed force protocols.

description: The migratory beekeeper follows the seasonal progression of flowering, moving bee colonies from one forage site to another. Migratory management of bee colonies offers the possibility of integrating two sources of income: the provision of commercial pollination services and the production of honey. There are numerous forage areas suitable for accommodating the bee colonies at each stage of migration, differing according to the location and the type of plants which cover them. The beekeeper therefore needs to address and resolve the problem of locating a sequence of forage sites to be followed throughout the migration. Given the seasonability of the crops produced on the forage areas, the analysis on the jointness in input may be carried out on two levels. On the first level, it is considered the single forage area, on the second level the sequence of forage areas.

description: We conducted a non-hypothetical choice experiment through a second price sealed bid experimental auction (Vickrey auction) to estimate the willingness to pay (WTP) to buy a new functional snack made with white lupine and citrus fiber, which are ingredients with high fiber content. A sample of 289 consumers were surveyed in Bologna and Catania in July 2015. The results confirm that consumers are willing to pay to buy functional foods, especially those who are looking for innovative products that are not influenced by the opinions of others in the buying decision. In addition, WTP did not depend exclusively on the functional properties but also on other characteristics such as appearance and taste of the snack.

description: We study the atom-light interaction in the fully quantum regime, with focus on off-resonant light scattering into a cavity from ultracold atoms trapped in an optical lattice. The detection of photons allows the quantum nondemolition (QND) measurement of quantum correlations of the atomic ensemble, distinguishing between different quantum states. We analyse the entanglement between light and matter and show how it can be exploited for realising multimode macroscopic quantum superpositions such as Schrödinger cat states, for both bosons and fermions. We provide examples utilising different measurement schemes, and study their robustness to decoherence. Finally, we address the regime where the optical lattice potential is a quantum dynamical variable and is modified by the atomic state, leading to novel quantum phases, and significantly altering the phase diagram of the atomic system.

description: Families raising children with autism contribute significant amounts to the cost of care. In this era of health care reform, families have more insurance choices, but people are unfamiliar with health insurance terms. This study uses 2 national data sets to examine health insurance ratings from parents raising children with autism and child expenditures to explore how these measures align.
Policies for innovations in the new Rural Development Programs (RDP): the Italian regional experience

description: The rural development policy for the period 2014-2020 gives an important role to the knowledge system and the innovation diffusion. In summary the main topics are: the same importance of tacit and scientific knowledge for the human capital development and the innovation diffusion, the better results for the innovation transfer when all the innovation chain players are involved (farmers, researchers, advisories etc.), the usefulness of the interactive approach to define farms’ problems and to find some innovative solutions. This article attempts to understand if the Europe 2020’s high and farsighted objectives had an effective implementation into the planning and rules of the Rural Development Regulation and if in Italy there are some ongoing problems.

description: This paper focuses on the estimation of low-complexity signals when they are observed through $M$ uniformly quantized compressive observations. Among such signals, we consider 1-D sparse vectors, low-rank matrices, or compressible signals that are well approximated by one of these two models. In this context, we prove the estimation efficiency of a variant of Basis Pursuit Denoise, called Consistent Basis Pursuit (CoBP), enforcing consistency between the observations and the re-observed estimate, while promoting its low-complexity nature. We show that the reconstruction error of CoBP decays like $M^{-1/4}$ when all parameters but $M$ are fixed. Our proof is connected to recent bounds on the proximity of vectors or matrices when (i) those belong to a set of small intrinsic "dimension", as measured by the Gaussian mean width, and (ii) they share the same quantized (dithered) random projections. By solving CoBP with a proximal algorithm, we provide some extensive numerical observations that confirm the theoretical bound as $M$ is increased, displaying even faster error decay than predicted. The same phenomenon is observed in the special, yet important case of 1-bit CS.

description: OBJECTIVES: To describe determinants of head impact magnitudes between various play aspects in high school football.

METHODS: Thirty-two high school American football players wore Head Impact Telemetry System instrumented helmets to capture head impact magnitude (linear acceleration, rotational acceleration, and Head Impact Technology severity profile [HITsp]). We captured and analyzed video from 13 games (n = 3888 viewable head impacts) to determine the following play aspects: quarter, impact cause, play type, closing distance, double head impact, player's stance, player's action, direction of gaze, athletic readiness, level of anticipation, player stationary, ball possession, receiving ball, and snapping ball. We conducted random intercepts general linear mixed models to assess the differences in head impact magnitude between play aspects (α = 0.05).

RESULTS: The following aspects resulted in greater head impact magnitude: impacts during the second quarter (HITsp: P = .03); contact with another player (linear, rotational, HITsp: P < .001); initial head impact when the head is struck twice (linear, rotational, HITsp: P < .001); longer closing distances, especially when combined with a 3-point stance or when being struck in the head (linear: P = .03); the 2-point stance (linear, rotational, HITsp: P < .001); and offensive linemen not snapping the ball compared with those snapping the ball (rotational: P = .02, HITsp: P = .02).

CONCLUSIONS: Preventing head impacts caused by contact with another player may reduce head impact magnitude in high school football. Rule or coaching changes that reduce collisions after long closing distances, especially when combined with the 3-point stance or when a player is being struck in the head, should be considered.
