description: We present new analysis of 11 intermediate-age (1-2 Gyr) star clusters in the Large Magellanic Cloud based on Hubble Space Telescope imaging data. Seven of the clusters feature main sequence turnoff (MSTO) regions that are wider than can be accounted for by a simple stellar population, whereas their red giant branches indicate a single value of [Fe/H]. The star clusters cover a range in present-day mass from about 1E4 to 2E5 solar masses. We compare radial distributions of stars in the upper and lower parts of the MSTO region, and calculate cluster masses and escape velocities from the present time back to a cluster age of 10 Myr. Our main result is that for all clusters in our sample with estimated escape velocities > 15 km/s at an age of 10 Myr, the stars in the brightest half of the MSTO region are significantly more centrally concentrated than the stars in the faintest half AND more massive red giant branch and asymptotic giant branch stars. This is not the case for clusters with escape velocities < 10 km/s at an age of 10 Myr. We argue that the wide MSTO region of such clusters is mainly caused by to a 200 - 500 Myr range in the ages of cluster stars due to extended star formation within the cluster from material shed by first-generation stars featuring slow stellar winds. Dilution of this enriched material by accretion of ambient interstellar matter is deemed plausible if the spread of [Fe/H] in this ambient gas was very small when the second-generation stars were formed in the cluster.

description: Dynamic renormalization group (RG) methods were originally used by Forster, Nelson and Stephen (FNS) to study the large-scale behaviour of randomly-stirred, incompressible fluids governed by the Navier-Stokes equations. Similar calculations using a variety of methods have been performed since, but have led to a discrepancy in results. In this paper, we carefully re-examine in $d$-dimensions the approaches used to calculate the renormalized viscosity increment and, by including an additional constraint which is neglected in many procedures, conclude that the original result of FNS is correct. By explicitly using step functions to control the domain of integration, we calculate a non-zero correction caused by boundary terms which cannot be ignored. We then go on to analyze how the noise renormalization, absent in many approaches, contributes an ${\mathcal O}(k^2)$ correction to the force autocorrelation and show conditions for this to be taken as a renormalization of the noise coefficient. Following this, we discuss the applicability of this RG procedure to the calculation of the inertial range properties of fluid turbulence.

description: Background/Objectives: Bringing small interfering RNA (siRNA) into the cell cytosol to achieve specific gene silencing is an attractive but also very challenging option for improved therapies. The first step for successful siRNA delivery is the complexation with a permanent cationic or ionizable compound. This protects the negatively charged siRNA and enables transfection through the cell membrane. The current study explores the performance of the innovative, ionizable lipid 2-Tetradecylhexadecanoic acid-(2-bis{[2-(2,6-diamino-1-oxohexyl)amino]ethyl}aminoethyl)-amide (T14diLys), in combination with 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (DOPE), for siRNA delivery and the impact of the production method (sonication vs. extrusion) on the particle properties. Methods: Liposomes were produced either with sonication or extrusion and characterized. The extruded liposomes were combined with siRNA at different N/P ratios and investigated in terms of size zeta potential, encapsulation efficiency, lipoplex stability against RNase A, and knockdown efficiency using enhanced green fluorescent protein (eGFP)-marked colon adenocarcinoma cells. Results: The liposomes prepared by extrusion were smaller and had a narrower size distribution than the sonicated ones. The combination of siRNA and liposomes at a nitrogen-to-phosphate (N/P) ratio of 5 had optimal particle properties, high encapsulation efficiency, and lipoplex stability. Gene knockdown tests confirmed this assumption. Conclusions: Liposomes produced with extrusion were more reproducible and provided enhanced particle properties. The physicochemical characterization and in vitro experiments showed that an N/P ratio of 5 was the most promising ratio for siRNA delivery.

description: During eternal inflation, a landscape of vacua can be populated by the nucleation of bubbles. These bubbles inevitably collide, and collisions sometimes displace the field into a new minimum in a process known as a classical transition. In this paper, we examine some new features of classical transitions that arise when gravitational effects are included. Using the junction condition formalism, we study the conditions for energy conservation in detail, and solve explicitly for the types of allowed classical transition geometries. We show that the repulsive nature of domain walls, and the de Sitter expansion associated with a positive energy minimum, can allow for classical transitions to vacua of higher energy than that of the colliding bubbles. Transitions can be made out of negative or zero energy (terminal) vacua to a de Sitter phase, re-starting eternal inflation, and populating new vacua. However, the classical transition cannot produce vacua with energy higher than the original parent vacuum, which agrees with previous results on the construction of pockets of false vacuum. We briefly comment on the possible implications of these results for various measure proposals in eternal inflation.

description: Background: Restorative solutions designed for edentulous patients such as dentures and their accompanying denture adhesives operate in the complex and dynamic environment represented by human oral physiology. Developing material models accounting for the viscoelastic behavior of denture adhesives can facilitate their further optimization within that unique physiological environment. This study aims to statistically quantify the degree of significance of three physiological variables - namely: temperature, adhesive swelling, and pH - on denture adhesive mechanical behavior. Further, based on these statistical significance estimations, a previously-developed viscoelastic material modelling approach for such denture adhesives is further expanded and developed to capture these variables’ effects on mechanical behavior. Methods: In this study a comparable version of Denture adhesive Corega Comfort was analysed rheologically using the steady state frequency sweep tests. The experimentally derived rheological storage and loss modulus values for the selected physiological variables were statistically analyzed using multi parameter linear regression analysis and the Pearson’s coefficient technique to understand the significance of each individual parameter on the relaxation spectrum of the denture adhesive. Subsequently, the parameters are incorporated into a viscoelastic material model based on Prony series discretization and time-temperature superposition, and the mathematical relationship for the loss modulus is deduced. Results: The results of this study clearly indicated that the variation in both the storage and loss modulus values can be accurately predicted using the oral cavity physiological parameters of temperature, swelling ratio, and pH with an adjusted R2 value of 0.85. The R2 value from the multi-parameter regression analysis indicated that the predictor variables can estimate the loss and storage modulus with a reasonable accuracy for at least 85% of the rheologically determined continuous relaxation spectrum with a confidence level of 98%. The Pearson’s coefficient for the independent variables indicated that temperature and swelling have a strong influence on the loss modulus, whereas pH had a weak influence. Based on statistical analysis, these mathematical relationships were further developed in this study. Conclusions: This multi-parameter viscoelastic material model is intended to facilitate future detailed numerical investigations performed with implementation of denture adhesives using the finite element method.

description: The Large High Altitude Air Shower Observatory project is proposed to study high energy gamma ray astronomy ( 40 GeV-1 PeV ) and cosmic ray physics ( 20 TeV-1 EeV ). The wide field of view Cherenkov telescope array, as a component of the LHAASO project, will be used to study energy spectrum and compositions of cosmic ray by measuring the total Cherenkov light generated by air showers and shower maximum depth. Two prototype telescopes have been in operation since 2008. The pointing accuracy of each telescope is crucial to the direction reconstruction of the primary particles. On the other hand the primary energy reconstruction relies on the shape of the Cherenkov image on the camera and the unrecorded photons due to the imperfect connections between photomultiplier tubes. UV bright stars are used as point-like objects to calibrate the pointing and to study the optical properties of the camera, the spot size and the fractions of unrecorded photons in the insensitive areas of the camera.

description: We make the cosmological constant, Λ, into a field and restrict the variations of the action with respect to it by causality. This creates an additional Einstein constraint equation. It restricts the solutions of the standard Einstein equations and is the requirement that the cosmological wave function possess a classical limit. When applied to the Friedmann metric it requires that the cosmological constant measured today, t_{U}, be Λ ~ t_{U}^(-2) ~ 10^(-122), as observed. This is the classical value of Λ that dominates the wave function of the universe. Our new field equation determines Λ in terms of other astronomically measurable quantities. Specifically, it predicts that the spatial curvature parameter of the universe is Ω_{k0} \equiv -k/a_(0)^(2)H^2= -0.0055, which will be tested by Planck Satellite data. Our theory also creates a new picture of self-consistent quantum cosmological history.

description: This study focuses on the impact of Covid-19 and the possible recovery roll-out of the hotel Industry.This is the single most important way the hospitality industry can develop trust from customers. There are two critical aspects here what you do to keep them safe, and how you communicate about what you are doing. Hotels found they could cut the rate of transmission of the virus among their own workers through universal masking, universal precautions and cleaning protocols. Some portion of the staff of all big businesses will be infected because of the high prevalence in communities. Whether employees attribute that infection to hotel business will be largely related to the efficacy of safety measures, and how well communicated that this was hotels top priority.The Covid-19 is a black swan event which has affected each and every industry in the world, however the effect it has had on the Travel & Hospitality sector in a very short period of time has been unseen or unheard of. The virus has unleashed itself across the world and India is no outlier, have been witnessing a steady increase in the number of active cases on a daily basis. The common consensus backed by medical experts has been that isolation and lockdown are the first steps in slowing down the spread of this virus.
title: Campus Gatekeeper Trainings: An Analysis of Question, Persuade, Refer (QPR) and SafeTALK

description: Suicide prevention gatekeeper trainings seek to equip learners with knowledge about suicide, skills to recognize suicide risk and intervene, and awareness of referral resources. Although these trainings are widely used, research is limited on their utility and impact on increasing intent to intervene in a suicide crisis. The current study aimed to evaluate two gatekeeper trainings, SafeTALK and Question, Persuade, Refer (QPR), on a college campus using a pre-test/post-test design to examine this gap in the literature and provide evidence to help shape gatekeeper trainings in the future. Because the theory of planned behavior has been demonstrated to be an effective framework for understanding an individual’s intention to intervene with someone at risk of suicide (Aldrich, 2015), the current study has been guided by this framework. Positive increases in attitudes about intervening, subjective norms, perceived behavioral control (PBC), and intention to intervene were found across both trainings. All variables were found to significantly predict intention to intervene in the overall model; however, only change in PBC predicted change in intention to intervene when controlling for other predictors. Training outcomes did not differ by type of training. An exploratory effect was found suggesting that positive attitudes about intervening increased only for participants who knew someone who died by, or attempted, suicide. Future research is needed to better understand gatekeeper training outcomes in larger, more diverse samples, settings (e.g., workplace, school, etc.), types of trainings, and related variables (e.g., exposure to suicide, occupation, gender, etc.).

description: We report that the average rotation speed of optically trapped crenated erythrocytes is direct signature of their membrane deformability. When placed in hypertonic buffer, discocytic erythrocytes are subjected to crenation. The deformation of cells brings in chirality and asymmetry in shape that make them rotate under the scattering force of a linearly polarized optical trap. A change in the deformability of the erythrocytes, due to any internal or environmental factor, affects the rotation speed of the trapped crenated cells. Here we show how the increment in erythrocyte membrane rigidity with adsorption of $Ca^{++}$ ions can be exhibited through this approach.

description: The spontaneous organization of collective activities in animal groups and societies has attracted a considerable amount of attention over the last decade. This kind of coordination often permits group-living species to achieve collective tasks that are far beyond single individuals capabilities. In particular, a key benefit lies in the integration of partial knowledge of the environment at the collective level. In this contribution we discuss various self-organization phenomena in animal swarms and human crowds from the point of view of information exchange among individuals. In particular, we provide a general description of collective dynamics across species and introduce a classification of these dynamics not only with respect to the way information is transferred among individuals, but also with regard to the knowledge processing at the collective level. Finally, we highlight the fact that the individuals' ability to learn from past experiences can have a feedback effect on the collective dynamics, as experienced with the development of behavioral conventions in pedestrian crowds.
A multidisciplinary journal club to support hospice research culture
Creators: name: Steele, Tom
name: Stanley, Sarah
name: Nwosu, Amara
Publisher: name: AMRC Open Research
Year: 2020

description: Background
 Research in palliative care is essential to improve outcomes for patients with terminal illness. Hospices are central to this, however research is not always embedded in a hospice culture.
 Journal clubs have been identified as a way of building a research culture in hospices, whilst
 sharing relevant research within teams and developing research skills of staff1.

 Aims
 The aim of this project was to develop regular forum to evaluate published evidence to:
 • Inform/improve clinical practice
 • Improve research skills across all disciplines
 • Identify future research questions

 Methods
 Journal club meetings were held fortnightly and co-ordinated by a speciality doctor with support from the research nurse, identifying presenters.
 Meetings were promoted to all hospice staff, with buy in from departmental leads.
 Sessions were one hour long, and guided by a facilitator. Outcomes were focused around three questions:
 - What are the main findings?
 - Should this change our practice?
 - What are the research questions?
 Summary was typed and circulated by e-mail to all staff within one week, and certificates given to presenters.

 Results
 Results have been positive. 19 meetings have taken place since January 2019. Multidisciplinary attendance has been maintained throughout, with some members of the MDT gaining confidence to present. Presenters have included nurses, physiotherapist, healthcare assistant,
 nursing students, medical students and various grades of doctors. Over 50 research questions have been generated.

 Conclusion
 This new model of journal club at Marie Curie Hospice Liverpool has led to a vastly improved attendance and engagement across disciplines, increasing exposure to research and its relevance to our practice.
 Key features are an openness to the whole multidisciplinary team, a focus on relevance to practice and integration with the research team at the hospice.
 The group discussions have generated a number of research questions that will influence projects in the future.
 Success has been sustained for a year with work ongoing to maintain this into the future.

description: Gamma-Ray Bursts (GRBs) are the most violent explosions in the Universe. Long duration GRBs are associated with the collapse of massive stars, rivaling their host galaxies in luminosity. The discovery of the most distant spectroscopically confirmed object in the Universe, GRB090423, opened a new window on the high redshift Universe, making it possible to study the cosmic 're-ionization' epoch and the preceding dark ages, as well as the generation of the first stars (Population III) using GRBs. Obviously this enables a wealth of new studies using the near infrared (nIR) characteristics of GRB afterglows. Here we explore a different path, focusing on the next generation of X-ray missions with large area focusing telescopes and fast repointing capabilities. We found that X-ray data can complement nIR observations and for the brightest GRBs can provide an accurate and independent redshift determination. Metallicity studies can also be carried out profitably once the redshift is known. Finally we discuss observational signatures of GRBs arising from Population III stars in the X-ray band.

Design of a solid tank prototype optical computed tomography scanner
Creators: name: Ogilvy, Andrew
Publisher: name: University of British Columbia
Year: 2018

description: Purpose: The objective of this work is to design a new prototype fan-beam optical computed tomography (OCT) scanner for three-dimensional radiation dosimetry. Primary distinctions are a solid acrylic tank and the inclusion of iterative reconstruction techniques (IR) into the scanning methods. This scanner attempts to address artifacts related to color and index matching baths that are often found with OCT for gel dosimeters. As a result of the solid tank design there is lensing that the fan-beam experiences while passing through a gel dosimeter, this lensing makes filtered back projection (FBP) less suitable than IR for image reconstruction. Methods: The two distinct features of this scanner are the use of a solid tank as an alternative to refractive index (RI) matching baths, and the inclusion of IR rather than FBP for image reconstruction. A polished acrylic block functions as a solid tank that is used to reduce the effects of material RI mismatch. Five arrays of 64 photodiode detectors (0.8mm x 0.7mm) were run in series to collect optical projection data. The detectors sat flush against the acrylic. A gel rotates inside a hole in the acrylic block and each projection is taken at 0.5 degree steps for 360 degrees before and after irradiation. The scanner properties were evaluated by imaging radiochromic silicon gel dosimeters. Results: Spatial frequency was measured using the modulation transfer function found from the edge spread function of a cylindrical attenuating object. The average spatial frequency measured was 3.111 cycles/mm. Image geometry was measured by placing opaque objects of known geometry inside of a gel and comparing the ratio of their pixel distances to their ratio geometric distances. The pixel ratio found with this system was 2.63px/mm. Conclusion: This work provides an alternative to traditional matching bath methods of addressing color and index matching for OCT of gel dosimeters. The inclusion of iterative reconstruction provides an alternative to filtered back projection. The system is capable of scanning 0.8mm slices of cylindrical volumes in under 3 minutes.

description: The neocortex has a remarkably uniform neuronal organization, suggesting that common principles of processing are employed throughout its extent. In particular, the patterns of connectivity observed in the superficial layers of the visual cortex are consistent with the recurrent excitation and inhibitory feedback required for cooperative-competitive circuits such as the soft winner-take-all (WTA). WTA circuits offer interesting computational properties such as selective amplification, signal restoration, and decision making. But, these properties depend on the signal gain derived from positive feedback, and so there is a critical trade-off between providing feedback strong enough to support the sophisticated computations, while maintaining overall circuit stability. We consider the question of how to reason about stability in very large distributed networks of such circuits. We approach this problem by approximating the regular cortical architecture as many interconnected cooperative-competitive modules. We demonstrate that by properly understanding the behavior of this small computational module, one can reason over the stability and convergence of very large networks composed of these modules. We obtain parameter ranges in which the WTA circuit operates in a high-gain regime, is stable, and can be aggregated arbitrarily to form large stable networks. We use nonlinear Contraction Theory to establish conditions for stability in the fully nonlinear case, and verify these solutions using numerical simulations. The derived bounds allow modes of operation in which the WTA network is multi-stable and exhibits state-dependent persistent activities. Our approach is sufficiently general to reason systematically about the stability of any network, biological or technological, composed of networks of small modules that express competition through shared inhibition.

description: Background: Atopic dermatitis (AD) is a chronic skin condition that weakens the skin barrier, leading to increased trans-epidermal water loss and reduced skin moisture. Understanding how these changes in the skin barrier relate to AD severity in Mongolian children may offer insights that could apply to other regions facing similar environmental challenges. Methods: A cross-sectional study was conducted at the National Dermatology Center of Mongolia, involving 103 children with AD. Severity was assessed using the SCORAD index, and skin barrier function was measured through TEWL, skin moisture, and pH. Linear regression analyses were conducted, adjusting for age, skin physiological parameters, AD severity characteristics, and total IgE levels. Results: Among the participants, 48.54% were classified as having moderate AD, while 34.95% had severe AD. The mean SCORAD index was 43.19 ± 17.11. In the final adjusted regression analysis, higher TEWL was significantly associated with greater AD severity (non-lesional: B = 0.328, p = 0.004; lesional: B = 0.272, p = 0.007), while skin moisture showed an inverse association (non-lesional: B = −0.771, p < 0.001; lesional: B = −0.218, p < 0.001). The total IgE level was significantly higher in the severe AD group (p = 0.013). Although skin pH initially correlated with AD severity, it did not remain significant in multivariate analysis. Conclusions: This study emphasizes the role of skin barrier function, particularly increased TEWL and reduced moisture, in AD severity among Mongolian children.

description: In this study, we introduce an optimization framework aimed at enhancing the efficiency of motion priority design in scenarios involving automated and teleoperated robots within an industrial recovery context. The escalating utilization of industrial robots at manufacturing sites has been instrumental in mitigating human workload. Nevertheless, the challenge persists in achieving effective human-robot collaboration/cooperation where human workers and robots share a workspace for collaborative tasks. In the event of an industrial robot encountering a failure, it necessitates the suspension of the corresponding factory cell for safe recovery. Given the limited capacity of pre-programmed robots to rectify such failures, human intervention becomes imperative, requiring entry into the robot workspace to address the dropped object while the robot system is halted. This non-continuous manufacturing process results in productivity loss. Robotic teleoperation has emerged as a promising technology enabling human workers to undertake high-risk tasks remotely and safely. Our study advocates for the incorporation of robotic teleoperation in the recovery process during manufacturing failure scenarios, which is referred to as "Cooperative Tele-Recovery". Our proposed approach involves the formulation of priority rules designed to facilitate collision avoidance between manufacturing and recovery robots. This, in turn, ensures a continuous manufacturing process with minimal production loss within a configurable risk limitation. We present a comprehensive motion priority optimization framework, encompassing an HRC simulator-based priority optimization and a cooperative multi-robot controller, to identify optimal parameters for the priority function. The framework dynamically adjusts the allocation of motion priorities for manufacturing and recovery robots while adhering to predefined risk limitations.

Cyclic structures in algebraic (co)homology theories

Year: 2010
Subjects: subject: K-Theory and Homology (math.KT)
subject: Quantum Algebra (math.QA)

description: This note discusses the cyclic cohomology of a left Hopf algebroid ($\times_A$-Hopf algebra) with coefficients in a right module-left comodule, defined using a straightforward generalisation of the original operators given by Connes and Moscovici for Hopf algebras. Lie-Rinehart homology is a special case of this theory. A generalisation of cyclic duality that makes sense for arbitrary para-cyclic objects yields a dual homology theory. The twisted cyclic homology of an associative algebra provides an example of this dual theory that uses coefficients that are not necessarily stable anti Yetter-Drinfel'd modules.
Composition-structure-property relationships in magnesium yttrium aluminoborate glasses
Creators: name: Rebecca, Anne
Publisher: name: No Publisher Supplied

description: There is an increasing need for light-weight, strong and crack-resistant glasses for industrial applications. In order to design new glasses, a thorough understanding of relationships between composition, structure, and properties is required. This study attempts to shed more light on the composition-structure-property relationships in alumina-rich aluminoborate glasses. In the present work, MgO-Y2O3-Al2O3-B2O3 glasses have been fabricated by melt-quenching at temperatures ranging from 1600°C to 1650°C. The influence of the substitution of B2O3 by Al2O3 on the structure, thermal and mechanical properties of the glasses (hardness and crack resistance) have been investigated using magic angle spinning – nuclear magnetic resonance (MAS-NMR), differential scanning calorimetry (DSC) and Vickers indentation. Hardness and crack resistance of the glasses were found to correlate with their structure and composition. Furthermore, with Al2O3/B2O3 substitution, fragility, density and hardness were found to increase while glass forming ability as well as crack resistance decreased.

description: Between 1 June 2016 and 31 May 2017, 17 European Union (EU) and European Economic Area countries reported 4,096 cases associated with a multi-country hepatitis A (HA) outbreak. Molecular analysis identified three co-circulating hepatitis A virus (HAV) strains of genotype IA: VRD_521_2016, V16–25801 and RIVM-HAV16–090. We categorised cases as confirmed, probable or possible, according to the EU outbreak case definitions. Confirmed cases were infected with one of the three outbreak strains. We investigated case characteristics and strain-specific risk factors for transmission. A total of 1,400 (34%) cases were confirmed; VRD_521_2016 and RIVM-HAV16–090 accounted for 92% of these. Among confirmed cases with available epidemiological data, 92% (361/393) were unvaccinated, 43% (83/195) travelled to Spain during the incubation period and 84% (565/676) identified as men who have sex with men (MSM). Results depict an HA outbreak of multiple HAV strains, within a cross-European population, that was particularly driven by transmission between non-immune MSM engaging in high-risk sexual behaviour. The most effective preventive measure to curb this outbreak is HAV vaccination of MSM, supplemented by primary prevention campaigns that target the MSM population and promote protective sexual behaviour.
