description: We report progress on measuring the position of Sgr A* on infrared images, placing limits on the motion of the central star cluster relative to Sgr A*, and measuring the proper motionof Sgr A* itself. The position of Sgr A* has been determined to within 10 mas on infrared images. To this accuracy, the gravitational source (sensed by stellar orbits) and the radiative source (Sgr A*) are coincident. Proper motions of four stars measured both in the infrared and radio indicate that the central star cluster moves with Sgr A* to within 70 km/s. Finally, combining stellar orbital information with an upper limit of 8 km/s for the intrinsic proper motion of Sgr A* (perpendicular to the Galactic plane), we place a lower limit on the mass of Sgr A* of 4 x 10^5 Msun.

Exploring exercise adherence in phase III cardiovascular rehabilitation post myocardial infarction.
Creators: name: Taylor, Alyx
name: Mormen, Harvey
Publisher: name: The Health & Fitness Journal of Canada
Year: 2022

description: Background: Research evidence supports the use of exercise as an effective part of cardiovascular rehabilitation (CR), and for long-term reduction of risk factors for cardiovascular incidents. Research shows those who engage fully in CR exercise programmes build up stamina for activities they had previously enjoyed. The increased freedom and confidence can raise the overall quality of life. However, despite evidence of the efficacy of CR, only 15 – 30% of eligible patients attend and 50% of those discontinue the exercise by 12months. Purpose: The study explored the experience of exercise prior to and during phase III CR to inform strategies to encourage maintenance of regular exercise as a lifestyle change. Methods: Qualitative data was collected from six volunteers (35–75years), who had recently undertaken exercise prescribed in phase III CR, through one-to-one semi-structured interviews. Interpretive phenomenological analysis from a critical realist perspective was undertaken independently by two researchers. Results: Themes included potential keys to address the aim of the study. First, “incidental exercise”, revealed physical fitness was previously incidental to motivations for taking exercise, for example: to engage competitively; to engage in social interactions; or to relax through leisure activity. The themes “normality” captured the desire to regain former capabilities and “self-evaluation” the desire to regularly measure change in physical fitness, or compare oneself with others. Conclusions: Qualitative analysis revealed possible target areas for enhancing positive experience of exercise in phase III CR programmes and potentially encouraging lifestyle change. Funding: None.

A new powerful method for probing the atmospheres of transiting exoplanets
Creators: name: Snellen, I. A. G.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Although atmospheric transmission spectroscopy of HD209458b with the Hubble Space Telescope has been very successful, attempts to detect its atmospheric absorption features using ground-based telescopes have so far been fruitless. Here we present a new method for probing the atmospheres of transiting exoplanets which may be more suitable for ground-based observations, making use of the Rossiter effect. During a transit, an exoplanet sequentially blocks off light from the approaching and receding parts of the rotating star, causing an artificial radial velocity wobble. The amplitude of this signal is directly proportional to the effective size of the transiting object, and the wavelength dependence of this effect can reveal atmospheric absorption features, in a similar way as with transmission spectroscopy. The advantage of this method over conventional atmospheric transmission spectroscopy is that it does not rely on accurate photometric comparisons of observations on and off transit, but instead depends on the relative velocity shifts of individual stellar absorption lines within the same on-transit spectra. We used an archival VLT/UVES data set to apply this method to HD209458. The amplitude of the Rossiter effect is shown to be 1.7+-1.2 m/sec higher in the Sodium D lines than in the weighted average of all other absorption lines in the observed wavelength range, corresponding to an increment of 4.3+-3% (1.4 sigma). The uncertainty in this measurement compares to a photometric accuracy of 5e-4 for conventional atmospheric transmission spectroscopy, more than an order of magnitude higher than previous attempts using ground-based telescopes. Observations specifically designed for this method could increase the accuracy further by a factor 2-3.

Power Law Plateau Inflation Potential In The RS $II$ Braneworld Evading Swampland Conjecture

description: In the recent time, inflationary cosmology is facing an existential crisis due to the proposed Swampland criterion which aims to evade any (meta-)stable de Sitter construction within the String landscape. It is been realised that a single field slow roll inflation is inconsistent with the Swampland criterion unless the inflationary model in realised in some non standard scenario such as Warm inflation or the Braneworld scenario. In \cite{Dimopoulos}, Dimopoulos and Owen introduced a new class of model of inflation dubbed as the power law plateau inflation in the standard cold inflationary scenario. But to realise this model in the standard scenario consistent with observation, they had to introduce a phase of thermal inflation. In this paper we have analysed this model in the braneworld scenario to show that for some choice of the parameters defining the model class, one can have an observationally consistent power law plateau without any phase of thermal inflation. We have also shown that, for the correct choice of model parameters, one can easily satisfy the Swampland criterion. Besides, for a particular choice of the potential one can also satisfy the recently proposed Trans-Planckian Censorship Conjecture.

description: We study the role of the noise in the dynamics of two competing species. We consider generalized Lotka-Volterra equations in the presence of a multiplicative noise, which models the interaction between the species and the environment. The interaction parameter between the species is a random process which obeys a stochastic differential equation with a generalized bistable potential in the presence of a periodic driving term, which accounts for the environment temperature variation. We find noise-induced periodic oscillations of the species concentrations and stochastic resonance phenomenon. We find also a nonmonotonic behavior of the mean extinction time of one of the two competing species as a function of the additive noise intensity.

Four-Impurity Operators and String Field Theory Vertex in the BMN Correspondence

description: In the context of the Penrose/BMN limit of the AdS/CFT correspondence, we consider four-impurity BMN operators in Yang-Mills theory, and demonstrate explicitly their correspondence to four-oscillator states in string theory. Using the dilatation operator on the gauge-theory side of the correspondence, we calculate matrix elements between four-impurity states. Since conformal dimensions of gauge-theory operators correspond to light-cone energies of string states, these matrix elements may be compared with the string-theory light-cone Hamiltonian matrix elements calculated in the plane-wave background using the string field theory vertex. We find that the two calculations agree, extending the cases of two- and three-impurity operators considered in the literature using BMN gauge-theory quantum mechanics. The results are also in agreement with calculations in the literature based on perturbative gauge-theory methods.

Getting chirality right: single scalar leptoquark solutions to the $(g-2)_{e,μ}$ puzzle

description: We identify the two scalar leptoquarks capable of generating sign-dependent contributions to leptonic magnetic moments, $R_2\sim (\mathbf{3}, \mathbf{2}, 7/6)$ and $S_1\sim (\mathbf{3}, \mathbf{1}, -1/3)$, as favoured by current measurements. We consider the case in which the electron and muon sectors are decoupled, and real-valued Yukawa couplings are specified using an up-type quark mass-diagonal basis. Contributions to $Δa_e$ arise from charm-containing loops and $Δa_μ$ from top-containing loops -- hence avoiding dangerous LFV constraints, particularly from $μ\to e γ$. The strongest constraints on these models arise from contributions to the Z leptonic decay widths, high-$p_T$ leptonic tails at the LHC, and from (semi)leptonic kaon decays. To be a comprehensive solution to the $(g-2)_{e/μ}$ puzzle we find that the mass of either leptoquark must be $\lesssim 65$ TeV. This analysis can be embedded within broader flavour anomaly studies, including those of hierarchical leptoquark coupling structures. It can also be straightforwardly adapted to accommodate future measurements of leptonic magnetic moments, such as those expected from the Muon $g-2$ collaboration in the near future.

description: Background: Methods for studying physical activity and sleep in anorexia nervosa vary, preventing comparison. However, most studies suggest physical activity and sleep behaviour influence treatment outcomes in anorexia nervosa. Purpose: Transparent reporting of physical activity and sleep behaviour in anorexic patients at the beginning of treatment. Methods: 43 female anorexia nervosa patients at an in-patient ward were recruited. Within eight days of admission participants wore a three-axis accelerometer (Axivity) for a week. The first and last day were omitted. Data was analysed with the R package GGIR, with acceleration expressed in Euclidean norm minus one (ENMO). Results: After exclusion due to low compliance and corrupt data 28 participants remained. Their mean (SD) age was 17.8 (7.0) years and age adjusted BMI was 15.9 (3.8) kg/m2. Mean sleep duration was 7.1 (0.8) h and sleep efficiency was 90 (4) %. Twenty-three participants did not reach sleep duration recommendations, with the largest discrepancy seen in young patients (p<0.001). Daytime ENMO was 16.5 (3.7) mg and the highest coherent 30-minute ENMO bout was 47.3 (11.3) mg. There was no significant correlation across the five days in duration and efficiency of sleep, daytime ENMO or highest coherent 30-minute ENMO bout. Conclusion: Physical activity can be kept low and sleep quality high in an in-patient ward for anorexic patients. Sleep duration might be a problem, especially for younger individuals, where treatment need to account for their increased sleep requirements. There appears to be no habituation effect during treatment. Funding: The Mandometer clinics.

description: Recent advances in digital beam forming for phased arrays in combination with digital signal processing should enable the development of multibeam radar in a bistatic configuration. In the bistatic setting, the pulse travelling outward from the transmitter should be followed or "chased" by the receiver. During transmission, depending on the location of the transmitter, receiver, and pulse, the number of digital beams and their location at the transmitter vary. In this paper, we analyse the geometrically depending number of digital beams and the beam switching rate of the receiver needed for pulse chasing. In addition, we derive the pulse repetition frequency (PRF) for the bistatic configuration based on the desired detection range. It is shown that the PRF in the bistatic case can be increased compared to its monostatic counterpart when the distance between the transmitter and the receiver is increased. Our results are applied on the scenario of an air traffic control radar to show the feasibility of a multibeam, ground based bistatic surveillance radar. It will be demonstrated that the maximum PRF can almost be doubled and an adaptive sensing and tracking paradigm can lead to a maximum of 64 simultaneous receiver beams for the bistatic surveillance and tracking setting.

description: Background: Activity pacing has the potential to change physical activity (PA) behaviour, and reduce the high prevalence of physical inactivity in people with multiple sclerosis (MS). However, little is known about the association between PA behaviour and naturalistic pacing in this population. Purpose: To explore association between PA behaviour and naturalistic pacing in adults with MS. Methods: 21 people with MS (mean age= 59 ± 9 years) wore an accelerometer that measured free-living PA behaviour for 7 days and filled in questionnaires on their activity pacing, fatigue, and health-related quality of life (HRQoL). PA behaviour was assessed by examining activity level and activity variability (an index of activity pattern). Associations between the variables were examined using hierarchical regression. Results: Activity level, activity variability, engagement in pacing, fatigue and HRQoL were 241.07 (144.68), 3.96 ± .72, 3.25 ± .74, 4.75 ± 1.62 and 42.66 ± 8.13 respectively. Lower activity level was negatively associated with higher engagement in pacing (β= -.438, t= -2.66, p= .024), whereas there was no association between activity variability and engagement in pacing (β= -.225, t= -.96, p= .361). Conclusion: The negative association between activity level and activity pacing suggests that those with lower activity levels could be inappropriately using activity pacing as a reactionary response to their symptoms. As PA can help to prevent physical deconditioning and improve MS symptoms, further research into activity pacing as a potential strategy for increasing PA levels in people with MS is warranted.

description: Volcano eruption forecast remains a challenging and controversial problem despite the fact that data from volcano monitoring significantly increased in quantity and quality during the last decades.This study uses pattern recognition techniques to quantify the predictability of the 15 Piton de la Fournaise (PdlF) eruptions in the 1988-2001 period using increase of the daily seismicity rate as a precursor. Lead time of this prediction is a few days to weeks. Using the daily seismicity rate, we formulate a simple prediction rule, use it for retrospective prediction of the 15 eruptions,and test the prediction quality with error diagrams. The best prediction performance corresponds to averaging the daily seismicity rate over 5 days and issuing a prediction alarm for 5 days. 65% of the eruptions are predicted for an alarm duration less than 20% of the time considered. Even though this result is concomitant of a large number of false alarms, it is obtained with a crude counting of daily events that are available from most volcano observatories

description: Let X be a K3 surface with a polarization H with H^2=2rs. Assume that H.N(X)=Z for the Picard lattice N(X). The moduli space Y of sheaves over X with the Mukai vector (r,H,s) is again a K3 surface. We prove that Y\cong X, if there exists h_1\in N(X) with (h_1)^2=f(r,s), H.h_1\equiv 0\mod g(r,s), and h_1 satisfies some condition of primitivity. Existence of such type a criterion is surprising, and also gives some geometric interpretation of elements in N(X) with negative square. We describe all 18-dimensional irreducible components of moduli of the (X,H) with Y\cong X and prove that their number is infinite. These generalizes results of math.AG/0206158, math.AG/0304415 for r=s.

These results are roughly consistent with there being no evolution of the radio-loud QSO fraction out to z~6. Three sources have been detected at 250 GHz or 350 GHz at much higher levels than their 1.4 GHz flux densities suggesting that the observed mm emission is likely thermal emission from warm dust, although more exotic possibilities cannot be precluded. The highest redshift source in our sample (J1030+0524 at z=6.28) is not detected at 1.4 or 250 GHz, but four fairly bright radio sources (flux density at 1.4GHz > 0.2 mJy) are detected in a 2' field centered on the QSO, including an edge-brightened ('FRII') double radio source with an extent of about 1'. A similar over-density of radio sources is seen in the field of the highest redshift QSO J1148+5251. We speculate that these over-densities of radio sources may indicate clusters along the lines-of-sight, in which case gravitational lensing by the cluster could magnify the QSO emission by a factor 2 or so without giving rise to arcsecond-scale distortions in the optical images of the QSOs.

description: Obesity prevalence through childhood and adolescence has been classified as a serious public health problem noting a worldwide increase in the prevalence of overweight/obesity and therefore different etiologically related diseases. In developed countries, current prevalence levels reach 23.8% in boys and 22.6% in girls, with Portugal showing high prevalence values like other southern European and the Mediterranean countries (WHO, 2017). Not only for the health of the present generation of young adolescents but also for future adult’s populations, the need to find better multi-sectoral strategies for current public policies appears to be fundamental. Although it is not the main scope of this text, it will be important, in due course, to analyse the effectiveness of the current inter-sectoral health policies applied in some countries, although it is clear that no country until now has been able to definitively reverse this phenomenon. Our main purpose of this research note is to present the preliminary results of the Causes4adolescentObsesity (C4AO) project, which included a sample of 603 students from the northern and central interior region of Portugal.

description: Background: Adults on The Move Programme (AMP) is aiming to influence structures and operational cultures to ensure that the working-age population is physically active. The careers of Finns are most often cut short by musculoskeletal disorders (31%) as well as mental health problems (33%). Oulu University Hospital (OYS) implemented a four-year project to promote musculoskeletal health in co-operation with AMP. In OYS, the main reason for sick leave were musculoskeletal disorders (39%). Purpose: The aim was to manage work ability risks and reduce sick leaves by strenghtening musculoskeletal health. To achieve the level of physical condition required for work, to cope well at work and to have resources left for free time. Methods: Supervisors work ability management skills were developed. Based on workload measurements and work ability risks, employees were given advise and support how to improve physical condition and lifestyle or reduce workload through restorative exercise. Results: Employees increased exercise, lost weight, reduced stress and improved recovery. Absences from musculoskeletal disorders decreased by more than 2900 days. In money this means a saving of 872 400 euros (300 euros/day). Conclusion: Health and work ability management is included in strategy and financial planning. The employees’ motivation and responsibility for physical activity and healthy lifestyle has increased. The well-established activities and good practices have been continued since the end of the project. Funding: Funded by AMP (formerly Fit for Life Program).

description: Let $\mathbb F$ be a finite field. Consider a direct sum $V$ of an infinite number of copies of $\mathbb F$, consider the dual space $V^\diamond$, i.~e., the direct product of an infinite number of copies of $\mathbb F$. Consider the direct sum ${\mathbb V}=V\oplus V^\diamond$. The object of the paper is the group $\mathbf{GL}$ of continuous linear operators in $\mathbb V$. We reduce the theory of unitary representations of $\mathbf{GL}$ to projective representations of a certain category whose morphisms are linear relations in finite-dimensional linear spaces over $\mathbb F$. In fact we consider a certain family $ Q_α$ of subgroups in $\mathbb V$ preserving two-element flags, show that there is a natural multiplication on spaces of double cosets with respect to $ Q_α$, and reduce this multiplication to products of linear relations. We show that this group has type $\mathrm{I}$ and obtain an 'upper estimate' of the set of all irreducible unitary representations of $\mathbf{GL}$.

Year: 2022

description: Background: Physical fitness parameters of emergency service workers are closely related to their work performance. In these services, where the workload is excessive, the exercise habits of the workers are limited. Purpose: The study aimed to investigate the effect of the supervised combined exercise program applied to emergency service workers on physical activity and weekly step counts. Methods: Individuals working in the emergency service were divided into two groups as control group (CG) (n=29) and exercise group (EG) (n=25) by simple random method. Supervised combined exercise training (45 min a day/ 3 days a week/ 8 weeks) was given to the EG, no exercise program was given to the CG. Physical activity level (PAL) was assessed by self-administered International Physical Activity Questionnaire short form (IPAQ-S), daily step count evaluated by the pedometer program on individuals smartphones at baseline and after the 8 weeks training. Results: IPAQ-S score was higher in the EG than the CG after 8 weeks of training (p<0.01). In the comparison of the weekly number of steps in the EG, there was an increment between the 2nd-1st week ( p=0.019) and 6th-5th week ( p=0.041), no changes were observed in the other weeks (p>0.05). The weekly step counts were higher in the EG (p<0.05). Conclusions: Combined exercise training was effective on PAL in emergency service workers. Group-based exercise programs should be implemented to work hours for aiming the improvement overall health of healthcare professionals. Funding: No financial funding was received for the study.

description: Background: Prolonged workplace sitting is associated with increased risks of morbidity and mortality. Interventions to reduce workplace sitting time have demonstrated mixed results, suggesting context may play an important role. Purpose: To conduct a process evaluation to determine the intervention fidelity of three co-produced “Sit Less at Work” interventions implemented in diverse organisations with minimal researcher involvement to replicate the real-world context. Methods: A mixed methods “before and after” study design was used. Convenience samples of staff were recruited from three UK-based organisations (a small private sector business, a charity and a local authority) to complete pre- and post-intervention questionnaires and measures of workplace sitting time (using activPAL3™ devices) and participate in post-intervention focus groups. Intervention implementers and key personnel were recruited to participate in post-intervention focus groups/interviews. Results: None of the interventions were implemented as intended and no reductions in workplace sitting time were observed. Barriers to intervention implementation related to context and organisational culture and included workload pressures, the social norms of sitting, competing organisational priorities, and lack of management support. Conclusions: Shifts in organisational culture and ingrained social norms are required to support the effective implementation of future workplace sit less interventions. Such changes could be achieved with buy-in from all levels of management, by developing and implementing local policies and by ensuring adequate time and human resource investment. Funding: This project was funded by the National Institute for Health Research Doctoral Research Fellowship Programme (individual grant, DRF-2016-09-023).

Are Halos of Collisionless Cold Dark Matter Collisionless?

description: Much recent discussion about dark matter has been centered on two seemingly independent problems: the abundance of substructure in dark matter halos, and the cuspiness of the halos' inner density profile. We explore possible connections between the two problems by studying the gravitational scattering effects due to subhalos on the phase-space distribution of dark matter particles in the main halos. Our series of controlled numerical experiments indicates that the number and mass density of subhalos can be high enough to cause the collisionless dark matter particles in the inner part of a main halo to diffuse, flattening the main halo's inner cusp within a few dynamical times. Depending on the masses and concentration of the subhalos, the inner density profile of the whole system (main plus sub halos) can either steepen or flatten. Subhalo accretion can therefore introduce significant scatter in the inner density profiles of dark matter halos, offering a possible explanation for the range of profiles seen in both observations and cosmological simulations.

description: Background: Call centres workers spend up to 90% of their workday seated, often in prolonged periods (≥30 minutes) which can be detrimental to health, wellbeing and productivity. Purpose: To pilot a multicomponent intervention to sit less and move more, with (SLAMM+) and without (SLAMM) height-adjustable workstations, in contact centre call agents. Methods: Agents were individually randomized to SLAMM or SLAMM+ in this 10-month pilot trial. A mixed-methods evaluation assessed response, recruitment, retention, attrition and completion rates, adverse effects, trial feasibility and acceptability, preliminary effectiveness on worktime sitting, and secondary (cardiometabolic, wellbeing and work-related) outcomes. Intervention components were informed by formative research and underpinned by the COM-B model. Results: Intervention phases were mostly acceptable, though fluctuating call volumes impacted fidelity. Fifty-nine agents (68% female, 30.9±11.6 years) completed baseline. High staff turnover negatively impacted retention and completion rates. Agents ranked individual feedback, education sessions, and emails as the most important components for sitting less and moving more. The multicomponent intervention with height-adjustable workstations has potential to reduce total and prolonged sitting time at work over 3 and 10-months. More strategies are warranted to promote physical activity. Conclusions: Both interventions were mostly acceptable and feasible for promoting a reduction in total workday sitting time. The demonstrated findings will help prepare for a future randomized controlled trial designed to assess the effect of the interventions.

description: We study the dynamics and statics of a dilute batch minority game with random external information. We focus on the case in which the number of connections per agent is infinite in the thermodynamic limit. The dynamical scenario of ergodicity breaking in this model is different from the phase transition in the standard minority game and is characterised by the onset of long-term memory at finite integrated response. We demonstrate that finite memory appears at the AT-line obtained from the corresponding replica calculation, and compare the behaviour of the dilute model with the minority game with market impact correction, which is known to exhibit similar features.
