description: The purpose of this scoping review is to synthesize the current evidence on the risk and protective factors associated with mental health in children with brachial plexus birth injury (BPBI) and associated interventions. MEDLINE, EMBASE, and Cochrane databases were searched for reports on mental health in children with BPBI between 10 and 18 years. Risk and protective factors were charted using the VicHealth review and the Person–Environment–Occupation model. Of 732 records found, 133 full text reports were reviewed and 16 reports were included. Multiple mental health risks associated with BPBI were identified, while protective factors were largely unexplored. Person-related risks were most common including negative coping strategies (n = 8, 50%) and pain (n = 6, 38%). Most frequently reported environment and occupation risk factors were social difficulties (n = 9, 56%) and challenges with upper limb function and daily activities (n = 6, 38%). Good self-determination and/or self-concept (n = 5, 30%) was the most common protective factor. Research using a strengths-based approach is needed to elucidate protective factors and further understanding of the intersection of person and socio-cultural risk factors of mental health in children with BPBI. Evidence on mental health in children with brachial plexus birth injury largely comes from studies of quality of life and functional-status outcomes, while direct reports of mental health outcome in these children are lacking.Mental health risk factors in children with brachial plexus birth injury are largely understood by clinicians and researchers as person-related factors, while the multidimensional nature of these risks is relatively unexplored.Further investigation of mental health protective factors, such as resiliency and self-determination, will foster a strengths-based approach to rehabilitation in children with brachial plexus birth injury.

description: Though about 80 pulsar binaries have been detected in globular clusters so far, no pulsar has been found in a triple system in which all three objects are of comparable mass. Here we present predictions for the abundance of such triple systems, and for the most likely characteristics of these systems. Our predictions are based on an extensive set of more than 500 direct simulations of star clusters with primordial binaries, and a number of additional runs containing primordial triples. Our simulations employ a number N_{tot} of equal mass stars from N_{tot}=512 to N_{tot}=19661 and a primordial binary fraction from 0-50%. In addition, we validate our results against simulations with N=19661 that include a mass spectrum with a turn-off mass at 0.8 M_{sun}, appropriate to describe the old stellar populations of galactic globular clusters. Based on our simulations, we expect that typical triple abundances in the core of a dense cluster are two orders of magnitude lower than the binary abundances, which in itself already suggests that we don't have to wait too long for the first comparable-mass triple with a pulsar to be detected.

description: We present the far ultraviolet (FUV) imaging of the nearest Jellyfish or Fireball galaxy IC3418/VCC 1217, in the Virgo cluster of galaxies, using Ultraviolet Imaging Telescope (UVIT) onboard the ASTROSAT satellite. The young star formation observed here in the 17 kpc long turbulent wake of IC3418, due to ram pressure stripping of cold gas surrounded by hot intra-cluster medium, is a unique laboratory that is unavailable in the Milkyway. We have tried to resolve star forming clumps, seen compact to GALEX UV images, using better resolution available with the UVIT and incorporated UV-optical images from Hubble Space Telescope archive. For the first time, we resolve the compact star forming clumps (fireballs) into sub-clumps and subsequently into a possibly dozen isolated stars. We speculate that many of them could be blue supergiant stars which are cousins of SDSS J122952.66+112227.8, the farthest star (~17 Mpc) we had found earlier surrounding one of these compact clumps. We found evidence of star formation rate (4 - 7.4 x 10^-4 M_sun per yr ) in these fireballs, estimated from UVIT flux densities, to be increasing with the distance from the parent galaxy. We propose a new dynamical model in which the stripped gas may be developing vortex street where the vortices grow to compact star forming clumps due to self-gravity. Gravity winning over turbulent force with time or length along the trail can explain the puzzling trend of higher star formation rate and bluer/younger stars observed in fireballs farther away from the parent galaxy.

description: A possibility to detect correlations between two quantum mechanical systems only from the information of a subsystem is investigated. For generic cases, we prove that there exist correlations between two quantum systems if the time-derivative of the reduced purity is not zero. Therefore, an experimentalist can conclude non-zero correlations between his/her system and some environment if he/she finds the time-derivative of the reduced purity is not zero. A quantitative estimation of a time-derivative of the reduced purity with respect to correlations is also given. This clarifies the role of correlations in the mechanism of decoherence in open quantum systems.

description: Extremely elongated, conducting dust particles (also known as metallic "needles" or "whiskers") are seen in carbonaceous chondrites and in samples brought back from the Itokawa asteroid. Their formation in protostellar nebulae and subsequent injection into the interstellar medium have been demonstrated, both experimentally and theoretically. Metallic needles have been suggested to explain a wide variety of astrophysical phenomena, ranging from the mid-infrared interstellar extinction at ~3--8 micron to the thermalization of starlight to generate the cosmic microwave background. To validate (or invalidate) these suggestions, an accurate knowledge of the optics (e.g., the amplitude and the wavelength dependence of the absorption cross sections) of metallic needles is crucial. Here we calculate the absorption cross sections of iron needles of various aspect ratios over a wide wavelength range, by exploiting the discrete dipole approximation, the most powerful technique for rigorously calculating the optics of irregular or nonspherical grains. Our calculations support the earlier findings that the antenna theory and the Rayleigh approximation, which are often taken to approximate the optical properties of metallic needles are indeed inapplicable.

description: Music listening is widely used during exercise, but effects on physical activity are unknown. This review aimed to examine the effectiveness of music listening on physical activity of adults. Searches were conducted until September 2022. Eligible randomised controlled trials examined intentional music listening to enhance physical activity in adults. Trials were assessed using the Revised Cochrane risk-of-bias tool. The GRADE approach assessed certainty of evidence. One high and two low risk-of-bias trials (113 participants, 63–68 years) from cardiac and pulmonary rehabilitation programs were included. Moderate certainty evidence favoured music listening for total amounts of physical activity (n = 112, δ = 0.32, 95% CI = −0.06–0.70) and weekly moderate intensity physical activity (n = 88, MD = 52 min, 95% CI = −8–113). Low certainty evidence favoured music listening for exercise capacity (6-min walk test) (n = 79, MD = 101 metres, 95% CI = 2.32–199.88). There is imprecise, moderate certainty evidence that music listening increases physical activity by a small amount in older adults. Future research including adults of all ages with and without health conditions might investigate music listening with focussed behaviour change interventions.IMPLICATIONS FOR REHABILITATIONThere is uncertainty in the current evidence but listening to music may lead to small increases physical activity in older adults with health conditions.Listening to music while walking may lead to improved exercise capacity.Rehabilitation professionals might consider using music listening as an adjunct with focussed behaviour change interventions aiming to increase physical activity.

An Elementary System of Axioms for Euclidean Geometry based on Symmetry Principles

Publisher: name: arXiv
Year: 2021
Subjects: subject: History and Overview (math.HO)
subject: FOS: Mathematics

description: In this article, I develop an elementary system of axioms for Euclidean geometry. On one hand, the system is based on the symmetry principles which express our a priori ignorant approach to space: all places are the same to us (the homogeneity of space), all directions are the same to us (the isotropy of space) and all units of length we use to create geometric figures are the same to us (the scale invariance of space). On the other hand, through the process of algebraic simplification, this system of axioms directly provides Weyl's system of axioms for Euclidean geometry. The system of axioms, together with its a priori interpretation, offers new views to philosophy and pedagogy of mathematics: (i) it supports the thesis that Euclidean geometry is a priori, (ii) it supports the thesis that in modern mathematics the Weyl's system of axioms is dominant to Euclid's system because it reflects the a priori underlying symmetries, (iii) it gives a new and promising approach to learn geometry which, through the Weyl's system of axioms, leads from the essential geometric symmetry principles of the mathematical nature directly to modern mathematics.

description: Growing data volumes and velocities in fields such as Industry 4.0 or the Internet of Things have led to the increased popularity of data stream processing systems. Enterprises can leverage these developments by enriching their core business data and analyses with up-to-date streaming data. Comparing streaming architectures for these complex use cases is challenging, as existing benchmarks do not cover them. ESPBench is a new enterprise stream processing benchmark that fills this gap. We present its architecture, the benchmarking process, and the query workload. We employ ESPBench on three state-of-the-art stream processing systems, Apache Spark, Apache Flink, and Hazelcast Jet, using provided query implementations developed with Apache Beam. Our results highlight the need for the provided ESPBench toolkit that supports benchmark execution, as it enables query result validation and objective latency measures.

description: In this paper we study the possible microscopic origin of heavy-tailed probability density distributions for the price variation of financial instruments. We extend the standard log-normal process to include another random component in the so-called stochastic volatility models. We study these models under an assumption, akin to the Born-Oppenheimer approximation, in which the volatility has already relaxed to its equilibrium distribution and acts as a background to the evolution of the price process. In this approximation, we show that all models of stochastic volatility should exhibit a scaling relation in the time lag of zero-drift modified log-returns. We verify that the Dow-Jones Industrial Average index indeed follows this scaling. We then focus on two popular stochastic volatility models, the Heston and Hull-White models. In particular, we show that in the Hull-White model the resulting probability distribution of log-returns in this approximation corresponds to the Tsallis (t-Student) distribution. The Tsallis parameters are given in terms of the microscopic stochastic volatility model. Finally, we show that the log-returns for 30 years Dow Jones index data is well fitted by a Tsallis distribution, obtaining the relevant parameters.

description: No abstracts are to be cited without prior reference to the author.An offshore experimental dredging study was initiated off North Norfolk (UK) in 1992 to investigate the impacts of marine gravel extraction on macrobenthic invertebrates. A dredged 'treatment' and a non-dredged 'reference' site were selected to evaluate the initial impacts and subsequent processes of recolonisation. A survey of the benthos was conducted prior to the removal of about 50,000 tonnes of marine aggregate (sand and gravel) from the treatment site. Thereafter annual monitoring surveys were conducted, the first commencing immediately after the dredging episode. Preliminary results of this study (Kenny and Rees, 1994) indicated that whilst the dominant species recolonised quickly (i.e. within 8 months after dredging) the biomass remained significantly lower than its pre-dredged state, suggesting possible long-term effects on the community structure. A follow-up study (Kenny and Rees, 1996) suggested the substantially reduced biomass at the treatment site, some 24 months after dredging, was due to a local increase in sediment transport caused by tide and wave action occurring mainly over the winter period. This paper presents the physical and biological findings 3 years after dredging, and puts forward a generalised model of macrobenthic response to the effects of physical disturbance caused by dredging.

description: No abstracts are to be cited without prior reference to the author.Four research cruises in the Thames plume conducted over an annual cycle revealedthat it is a hypernutrified environment with strong horizontal gradients in nitrate (0-30pM) and silicate (0-10 pM) concentration. In addition, the phytoplankton communityin the Thames plume was found to be dominated by large (>20 p) cells at theinshore sites and by small (<5 p) cells at the offshore sites. At least two hypothesesexist to explain the latter observation. Firstly, the progressive removal of nitrate alongthe plume may force the size distribution to become increasingly biased towardssmaller species going offshore. Secondly, the progressive removal of silicate along theplume may reduce the proportion of diatoms in the mixed phytoplankton assemblage,consequently forcing the size distribution to become increasingly biased towardssmaller organisms going offshore. Shipboard mesocosm experiments were undertakento evaluate the probable mechanism driving the observed size distribution.Enrichment of the natural phytoplankton assemblage with nitrogen and phosphorusonly increased the absolute biomass but did not change the observed size distributionrelative to controls. In contrast, enrichment with nitrate, phosphate and silicateincreased the proportion of chlorophyll biomass in the >20 pn size fiaction as well asincreasing the absolute biomass. Consequently, we favour the second explanation forthe observed size distribution of chlorophyll.

description: The polarization properties of the elastic electron scattering on H-like ions are investigated within the framework of the relativistic QED theory. The polarization properties are determined by a combination of relativistic effects and spin exchange between the incident and bound electrons. The scattering of a polarized electron on an initially unpolarized ion is fully described by five parameters. We study these parameters for non-resonant scattering, as well as in the vicinity of LL resonances, where scattering occurs through the formation and subsequent decay of intermediate autoionizing states. The study was carried out for ions from $\txt{B}^{4+}$ to $\txt{Xe}^{53+}$. Special attention was paid to the study of asymmetry in electron scattering.

description: It is known from ensemble measurements that rubidium atoms trapped in solid parahydrogen have favorable properties for quantum sensing of magnetic fields. To use a single rubidium atom as a quantum sensor requires a technique capable of efficiently measuring the internal state of a single atom, such as laser-induced fluorescence. In this work we search for laser-induced fluorescence from ensembles of rubidium atoms trapped in solid parahydrogen and, separately, in solid neon. In parahydrogen we find no evidence of fluorescence over the range explored, and place upper limits on the radiative branching ratio. In neon, we observe laser induced fluorescence, measure the spectrum of the emitted light, and measure the excited state lifetime in the matrix. Bleaching of atoms from the excitation light is also reported.

description: The problem of quantum computation is studied via the quantum circuit model, when this type of computation is conducted on semiconductor technologies. Due to the need for larger fault tolerant quantum computing systems, this study focuses more on the major problem of quantum noise. A software simulation tool under the title name QuCirDET is developed to easily design quantum circuits and simulate quantum recovery protocols. The adopted protocol is proposed by Steane and encodes logical cicuits by stabilizer codes. The Monte Carlo method is employed to compare the performance of different encoding protocols. Moreover, noise simulation is extended and adjusted on a quantum dot model based on semiconductor materials. Consequently, this simulation method allowed the comparison of two different surface stabilizer codes with the quantum dot structure. A case study is provided to examine from many different aspects the performance of a quantum algorithm via QuCirDET. This quantum algorithm or circuit is part of a proposed method, which improves the sequence alignment problem. This circuit is examined in terms of consumption of resources, run-time, quality of results and noise tolerance under the protection of particular encoding protocols.

description: Spin-dipole mediated interactions between tightly confined metastable helium atoms couple the spin-polarized quintet ${}^{5}Σ^{+}_{g}$ state to the singlet ${}^{1}Σ^{+}_{g}$ state from which autoionization is highly probable, resulting in finite lifetimes for the trap eigenstates. We extend our earlier study on spherically symmetric harmonic traps to the interesting cases of axially symmetric anisotropic harmonic traps and report results for the lowest 10 states in "cigar-like" and "pancake-like" traps with average frequencies of 100 kHz and 1 MHz. We find that there is a significant suppression of ionization, and subsequent increase in lifetimes, at trap aspect ratios $A=p/q$, where $p$ and $q$ are integers, for those states that are degenerate in the absence of collisions or spin-dipole interactions.

description: Attention to paid work in clinical health care—clinical work-integrating care (CWIC)—might be beneficial for patients of working age. However, the perceptions and expectations of patients about CWIC are unknown. The aim of this study was to develop an understanding of current practices, needs, and expectations among patients for discussing work with a medical specialist. A qualitative study was undertaken involving patients with diverse medical conditions (n = 33). Eight online synchronous focus groups were held. A thematic analysis was then performed. Three themes emerged from the data: (1) the process of becoming a patient while wanting to work again, (2) different needs for different patients, (3) patients’ expectations of CWIC. We identified three different overarching categories of work-concerns: (a) the impact of work on disease, (b) the impact of disease or treatment on work ability, and (c) concerns when work ability remained decreased. For each category of concerns, patients expected medical specialists to perform differing roles.

description: Identifying and understanding quality phrases from context is a fundamental task in text mining. The most challenging part of this task arguably lies in uncommon, emerging, and domain-specific phrases. The infrequent nature of these phrases significantly hurts the performance of phrase mining methods that rely on sufficient phrase occurrences in the input corpus. Context-aware tagging models, though not restricted by frequency, heavily rely on domain experts for either massive sentence-level gold labels or handcrafted gazetteers. In this work, we propose UCPhrase, a novel unsupervised context-aware quality phrase tagger. Specifically, we induce high-quality phrase spans as silver labels from consistently co-occurring word sequences within each document. Compared with typical context-agnostic distant supervision based on existing knowledge bases (KBs), our silver labels root deeply in the input domain and context, thus having unique advantages in preserving contextual completeness and capturing emerging, out-of-KB phrases. Training a conventional neural tagger based on silver labels usually faces the risk of overfitting phrase surface names. Alternatively, we observe that the contextualized attention maps generated from a transformer-based neural language model effectively reveal the connections between words in a surface-agnostic way. Therefore, we pair such attention maps with the silver labels to train a lightweight span prediction model, which can be applied to new input to recognize (unseen) quality phrases regardless of their surface names or frequency. Thorough experiments on various tasks and datasets, including corpus-level phrase ranking, document-level keyphrase extraction, and sentence-level phrase tagging, demonstrate the superiority of our design over state-of-the-art pre-trained, unsupervised, and distantly supervised methods.

description: No abstracts are to be cited without prior reference to the author.Natural ecosystems are highly dynamical and flexible with respect to nutrient enrichment, and have an apparent ability to handle inputs of nutrients below a certain limit, or critical load,without manifestation of undesirable effects. The critical level may obviously be affected byecosystem structure. The main aim of the present experiments was to study and compare theshort-term ecological response of variable nutrient additions to different types of Europeancoastal waters by use of mesocosms. A gradient of nutrients (N, P, and Si, added in Redfieldratios) was added in increasing doses to 7-8 replicate mesocosms (12-14 m deep, 40-50 m3volume). All trophic levels and chemical and physical conditions were closely monitored for3 weeks. There was a general positive relationship between nutrient dose and chlorophyll concentrationin Baltic, Mediterranean, and NE Atlantic coastal waters. In systems added more than thenatural background levels of nutrients, the concentration of chlorophyll increased for 1-2weeks, where after it levelled off at a more or less constant saturation level. The relationshipbetween nutrient dose and the chlorophyll saturation level showed small deviations fromlinearity, but we found a relatively pronounced difference in dose-response for the types ofcoastal water analysed. The response in chlorophyll per unit of nitrogen (+phosphorous andsilica) added was lowest for the Mediterranean system and highest for the Baltic, whichshowed slightly higher response than the NE Atlantic system. The mechanisms behind theobserved responses and the applicability of mesocosms for estimating critical nutrient valuesfor natural open coastal systems are preliminary evaluated.

description: The cosmology of KK gravitinos in models with extra dimensions is considered. The main result is that the production of such KK modes is not compatible with an epoch of non--standard expansion after inflation. This is so because the BBN constraint on the zero mode forces the reduced five dimensional Planck mass $M_5$ down to values much smaller than the usual four dimensional one, but this in turn implies many KK states available for a given temperature. Once these states are taken into account one finds that there is no $M_5$ for which the produced KK gravitinos satisfy BBN and overclosure constraints. This conclusion holds for both flat and warped models in which only gravity propagates in the full spacetime.

Gentrification : an intra-urban predictive model

description: Since 1970, many inner-city neighbourhoods that were the domain of low-income groups occupying cheap, dilapidated housing have attracted higher socio-economic groups. As a consequence, capital invested has increased the condition and price of inner-city housing. This phenomenon is commonly called "gentrification." This thesis reviews the gentrification literature, analyzes gentrification within an economic framework, and uses regression analysis to test the following hypothesis: There is a lag between the first statge of gentrification, the start of demographic transition, and the second stage, rising real housing prices. An increase in real housing prices can, therefore, be predicted by observing which central neighbourhoods are beginning to undergo demographic change. The intra-urban gentrification model designed for this thesis regresses the change in real housing prices during the 1970s against the change in demographics during the 1960s. The sample is 95 inner-city census tracts from Vancouver, Ottawa-Hull, and Toronto. The conclusion from statistical analysis is that rising housing prices in gentrifying neighbourhoods can indeed be predicted by observing which inner-city neighbourhoods are starting to undergo demographic change.

description: Independent component analysis (ICA) has been widely used for blind source separation in many fields such as brain imaging analysis, signal processing and telecommunication. Many statistical techniques based on M-estimates have been proposed for estimating the mixing matrix. Recently, several nonparametric methods have been developed, but in-depth analysis of asymptotic efficiency has not been available. We analyze ICA using semiparametric theories and propose a straightforward estimate based on the efficient score function by using B-spline approximations. The estimate is asymptotically efficient under moderate conditions and exhibits better performance than standard ICA methods in a variety of simulations.

description: In this work, the spin dynamics of a single electron under parametric modulation of a lateral quantum dot's electrostatic potential in the presence of spin-orbit coupling is investigated. Numerical and theoretical calculations demonstrate that, by squeezing and/or moving the electron's wave function, spin rotations with Rabi frequencies on the order of tens of megahertz can be achieved with experimentally accessible parameters in both parabolic and square lateral quantum dots. Applications of parametric excitations for determining spin-orbit coupling parameters and for increasing the spin polarization in the electronic ground are demonstrated.
