The Set of Types ofn-Dimensional Semisimple and Cosemisimple Hopf Algebras Is Finite

In this paper we give a partial answer to the above statement, proving that the set of types of semisimple and cosemisimple Hopf algebras of a Ž . given dimension is finite in any characteristic . The proof uses the formalism of deformation theory of bialgebras which is concerned, from a Ž . geometrical point of view, with the study of the affine algebraic set B V of all bialgebra structures which can be defined on a vector space V. Ž . There are two basic facts regarding B V . First of all, the transport of Ž . Ž . structures defines an action of GL V on B V , such that the orbit of a bialgebra A contains all structures isomorphic to A, so the set of types of bialgebras on V is in a one-to-one correspondence with the set of orbits. Second, we are led in a natural way to a cohomology theory for bialgebras, Ž . Ž Ž . studying the tangent spaces T O and T B V , where O is the closure A A A A of the orbit through a bialgebra A. One of the most important results of the deformation theory of bialgebras is that the orbit of a bialgebra is open if the cohomology vanishes. Therefore, the number of orbits which correspond to bialgebras having trivial cohomology is finite. We obtain our result by proving that the cohomology of a semisimple Hopf algebra A vanishes if the characteristic of k is 0, or more generally, if A is
Inconsistent Association between Perceived Air Quality and Self-Reported Respiratory Symptoms: A Pilot Study and Implications for Environmental Health Studies

As public awareness of air quality issues becomes heightened, people’s perception of air quality is drawing increasing academic interest. However, data about people’s perceived environment need scrutiny before being used in environmental health studies. In this research, we examine the associations between people’s perceptions of air quality and their self-reported respiratory health symptoms. Spearman rank correlation coefficients were estimated and the associations were tested at the 95% confidence level. Using data collected from participants in two representative communities in Hong Kong, the results indicate a weak but significant association between people’s perceived air quality and their self-reported frequency of respiratory symptoms. However, there are disparities in such an association between different genders, age groups, household income levels, education levels, marital statuses, and geographic contexts. The most striking disparities are between genders and geographic contexts. Multiple significant associations were observed for male participants (correlation coefficients: 0.169~0.205, p-values: 0.021~0.049), while none was observed for female participants. Besides, multiple significant associations were observed in the old town (correlation coefficients: 0.164~0.270, p-values: 0.003~0.048), while none was observed in the new town. The results have significant implications for environmental health research using social media data, whose reliability depends on the association between people’s perceived or actual environments and their health outcomes. Since inconsistent associations exist between different groups of people, researchers need to scrutinize social media data before using them in health studies.
A systematic review of the effectiveness of patient education through patient portals

Abstract Objective The objective of this study was to systematically review all literature studying the effect of patient education on patient engagement through patient portals. Introduction Patient portals provide patients access to health records, lab results, medication refills, educational materials, secure messaging, appointment scheduling, and telehealth visits, allowing patients to take a more active role in their health care decisions and management. A debate remains around whether these additional aids actually improve patient engagement and increase their ability to manage their own health conditions. This systematic review looks specifically at the effect of educational materials included in patient portals. Materials and Methods In accordance with PRISMA guidelines, the literature search was mapped across 5 databases (PubMed, CINAHL, Scopus, PsychINFO, Embase), and implemented on June 2, 2020. Results Fifty-two studies were included in the review. Forty-six (88.5%) reported rates of patient utilization of educational resources in the patient portal. Thirty (57.9%) shared patients’ perceptions of the usefulness of the education materials. Twenty-one (40.4%) reported changes in health outcomes following educational interventions through the patient portal. This review found that efforts are indeed being made to raise awareness of educational resources in patient portals, that patients are increasingly utilizing these resources, that patients are finding them useful, and that they are improving health outcomes. Conclusion It seems that patient portals are becoming a powerful tool for patient education and engagement, and show promise as a means of achieving the quadruple aim of healthcare. Moving forward, research should establish more uniform methods of measurement in order to strengthen the literature surrounding the effectiveness of patient education through patient portals.
A scoping review of system-level mechanisms to prevent children being in out-of-home care

Abstract Identifying which approaches can effectively reduce the need for out-of-home care for children is critically important. Despite the proliferation of different interventions and approaches globally, evidence summaries on this topic are limited. This study is a scoping review using a realist framework to explore what research evidence exists about reducing the number of children and young people in care. Searches of databases and websites were used to identify studies evaluating intervention effect on at least one of the following outcomes: reduction in initial entry to care; increase in family reunification post care. Data extracted from papers included type of study, outcome, type and level of intervention, effect, mechanism and moderator, implementation issues and economic (EMMIE) considerations. Data were coded by: primary outcome; level of intervention (community, policy, organisation, family or child); and type of evidence, using the realist EMMIE framework. This is the first example of a scoping review on any topic using this framework. Evaluated interventions were grouped and analysed according to system-level mechanism. We present the spread of evidence across system-level mechanisms and an overview of how each system-level mechanism might reduce the number of children in care. Implications and gaps are identified.
The Vastus Lateralis Muscle Interstitium Proteome Changes after an Acute Nociception in Patients with Fibromyalgia Compared to Healthy Subjects—A Microdialysis Study

Fibromyalgia (FM) is a complex disorder and a clinical challenge to diagnose and treat. Microdialysis is a valuable tool that has been used to investigate the interstitial proteins and metabolites of muscle in patients with fibromyalgia. The implantation of the catheter in the muscle causes acute tissue trauma and nociception. The aim of this study was to investigate acute proteome changes in the vastus lateralis muscle in women fibromyalgia patients (FM) and healthy subjects (CON). A further aim was to study if a 15-week resistance exercise program in FM had any influence on how chronic painful muscle responds to acute nociception. Twenty-six women patients with FM and twenty-eight CON were included in this study. A microdialysis catheter (100 kilo Dalton cut off, membrane 30 mm) was inserted in the vastus lateralis muscle, and samples were collected every 20 min. Subjects rated pain before catheter insertion, directly after, and every 20 min of sample collection. Dialysate samples from time points 0–120 were pooled and considered trauma samples due to the catheter insertion. The samples were analyzed with nano-liquid chromatography-tandem mass spectrometry (nLC-MS/MS). Advanced multivariate data analysis was used to investigate protein profile changes between the groups. Multivariate data analysis showed significant (CV-ANOVA p = 0.036) discrimination between FM and CON based on changes in 26 proteins. After the 15-week exercise intervention, the expression levels of the 15 proteins involved in muscle contraction, response to stimulus, stress, and immune system were increased to the same expression levels as in CON. In conclusion, this study shows that microdialysis, in combination with proteomics, can provide new insights into the interstitial proteome in the muscle of FM. In response to acute nociception, exercise may alter the innate reactivity in FM. Exercise may also modulate peripheral muscle proteins related to muscle contraction, stress, and immune response in patients with FM.
Heat Shock Protein Response to Stress in Poultry: A Review

Simple Summary The demand for poultry production is growing along with the human population, and supplying sufficient animal protein remains an ultimate priority. Securing food for future generations may have wide-ranging implications for poultry well-being. Heat shock proteins (HSPs) have been studied extensively in poultry to assess stress levels in different circumstances. However, the information on HSP expression is scattered; therefore, the present review attempts to signify the importance of HSPs in various conditions, focusing mainly on poultry. Considering the importance of poultry well-being, the synthesis and release of HSPs are primarily associated with the birds’ ability to cope with different stress conditions. Abstract Compared to other animal species, production has dramatically increased in the poultry sector. However, in intensive production systems, poultry are subjected to stress conditions that may compromise their well-being. Much like other living organisms, poultry respond to various stressors by synthesising a group of evolutionarily conserved polypeptides named heat shock proteins (HSPs) to maintain homeostasis. These proteins, as chaperones, play a pivotal role in protecting animals against stress by re-establishing normal protein conformation and, thus, cellular homeostasis. In the last few decades, many advances have been made in ascertaining the HSP response to thermal and non-thermal stressors in poultry. The present review focuses on what is currently known about the HSP response to thermal and non-thermal stressors in poultry and discusses the factors that modulate its induction and regulatory mechanisms. The development of practical strategies to alleviate the detrimental effects of environmental stresses on poultry will benefit from detailed studies that describe the mechanisms of stress resilience and enhance our understanding of the nature of heat shock signalling proteins and gene expression.
Working Conditions and Mental Health in a Brazilian University

The highest prevalence of mental illnesses and mental suffering in contemporary society has raised awareness of the theme and their connection to work. In Brazil, university servants (professors and technical-administrative staff) are a focused occupational group. We developed this research with the objective of exploring the relationship between the perception of working conditions and the mental health of these servants. Structured questionnaires were applied to 285 servants, 33.5% being professors and 66.5% technical-administrative staff. Regarding working conditions, the questionnaires included items that measured 15 primary factors and questions about their contracts and legal conditions. To evaluate mental health, the participants answered a questionnaire about common psychic symptoms, negative and positive affects, self-esteem, and family-work conflict. We composed groups of participants according to their mental health indicator scores (cluster analysis), and after that, we compared the mean scores in working conditions for the groups. Then, we found that the mean scores of 13 from the 15 working condition factors were significantly different between the mental health groups. Our results showed the importance of improving working conditions in universities to prevent mental illnesses. Understanding the content of each working condition factor presents potency to contribute to defining the priorities among different aspects of working conditions.
Longitudinal evaluation of serum microRNAs as biomarkers for neuroblastoma burden and therapeutic p53 reactivation

Abstract Accurate assessment of treatment response and residual disease is indispensable for the evaluation of cancer treatment efficacy. However, performing tissue biopsies for longitudinal follow-up poses a major challenge in the management of solid tumours like neuroblastoma. In the present study, we evaluated whether circulating miRNAs are suitable to monitor neuroblastoma tumour burden and whether treatment-induced changes of miRNA abundance in the tumour are detectable in serum. We performed small RNA sequencing on longitudinally collected serum samples from mice carrying orthotopic neuroblastoma xenografts that were exposed to treatment with idasanutlin or temsirolimus. We identified 57 serum miRNAs to be differentially expressed upon xenograft tumour manifestation, out of which 21 were also found specifically expressed in the serum of human high-risk neuroblastoma patients. The murine serum levels of these 57 miRNAs correlated with tumour tissue expression and tumour volume, suggesting potential utility for monitoring tumour burden. In addition, we describe serum miRNAs that dynamically respond to p53 activation following treatment of engrafted mice with idasanutlin. We identified idasanutlin-induced serum miRNA expression changes upon one day and 11 days of treatment. By limiting to miRNAs with a tumour-related induction, we put forward hsa-miR-34a-5p as a potential pharmacodynamic biomarker of p53 activation in serum.
Insect normal hovering flight in ground effect

The ground effect on insect normal hovering is investigated using an immersed boundary-lattice Boltzmann method to solve the two-dimensional incompressible Navier–Stokes equations. A virtual model of an elliptic foil with oscillating translation and rotation near a body surface or ground is used. Computations have been carried out for some parameters including the distance between the foil and the surface, phase difference between the rotation and translation, and amplitude of oscillating rotation. The ground effect on the unsteady forces and vortical structures is analyzed. In particular, three typical regimes of force behavior due to the ground effect, i.e., force enhancement, force reduction, and force recovery regime, are identified and closely associated with the evolution of vortex structures. The results obtained in this study provide physical insight into the understanding of aerodynamics and flow structures for insect normal hovering flight with a ground effect and flying mechanisms relevant to insect perching on body.
Characterization of optimality for the abstract convex program with finite dimensional range

Abstract This paper presents characterizations of optimality for the abstract convex program when S is an arbitrary convex cone in a finite dimensional space, Ω is a convex set and p and g are respectively convex and S-convex (on Ω). These characterizations, which include a Lagrange multiplier theorem and do not presume any a priori constraint qualification, subsume those presently in the literature.

A new measurement of the facular contrast near the solar limb

A new measurement of the contrast of solar faculae at 525 nm and 800 nm is presented using photometer data taken during the summer of 1982. The authors find that the contrast is decreasing with heliocentric angle Theta from mu approx. 0.2 to mu approx. 0.08, where mu = cos Theta. Parameterizing the contrast function with (Delta I)/I = 0.2 + alpha(mu - 0.2) over the range 0.08 < or = mu < or = 0.2, they obtain the best fit values of alpha: alpha(green) = 0.33 + or - 0.14, and alpha(red) = 0.25 + or - 0.08. These results differ from the facular contrast measurement of Chapman and Klabunde, who find the contrast increasing toward the limb. Selection effects in their data are suggested that could explain the discrepancy. These results are in good agreement with the facular model of Spruit, assuming a fixed magnetic field strength of 2000 gauss.
External gamma radiation dose rates in coastal Karnataka

External gamma-ray dose rates in air have been measured using a sensitive plastic scintillometer in the environment of coastal Karnataka, on the south west coast of India, where intensive industrial activities including a nuclear power plant, a super thermal power station and a petrochemical complex are envisaged. The gamma dose rates in air range from 26 to 174 nGy h-1 with a geometric mean of 74 nGy h-1 and geometric standard deviation of 1.4. The activity of primordial radionuclides in soil samples of the region were measured using an HPGe gamma ray spectrometer and the resulting doses in air were calculated. The mean absorbed dose rate due to primordial radionuclides was 41.4 nGy h-1 with a geometric standard deviation of 1.4. A correlation was found between doses measured using scintillometer and doses estimated from the measured activity of primordial radionuclides when the cosmic ray component is taken into account. The concentration of primordial radionuclides in soil and sand show considerable variation in their vertical depth distribution in the high background area of the region.
Evaluation of lattice sums using Poisson's summation formula. II

For pt.I see J. Math. Phys., vol.16, p.1457 of 1975. Application of Poisson's summation formula for the analytic evaluation of a class of lattice sums in arbitrary dimensions is extended to a more generalized class of sums. The resulting formulae are applicable to a variety of problems such as electronic-structure studies of crystalline solids, the onset of Bose-Einstein condensation in finite systems, the analysis of stability of quantized vortex arrays in extreme type-II superconductors and in rotating superfluid helium, plasma oscillations in an array of filamentary conductors, etc. They also provide an alternative approach for the determination of Madelung constants and other related sums that appear in the theory of cubic lattices.
On the reversibility of the input and output processes for a general birth-and-death queueing model

In this paper we consider the general birth-and-death queueing model of Natvig (1975). Define the input and output processes by the steady-state behaviour of respectively successive input and output intervals. Ignoring balking customers, two cases are considered. In the first case we treat a lost customer neither as an input nor as an output, then secondly as both. For both cases we show the input and output processes to be reverse processes. One mistake and two erroneous comments in Natvig (1975) are also corrected.
On the spanwise correlation of vortex shedding from a circular cylinder at high subcritical Reynolds number

The three‐dimensionality of the vortex shedding from a circular cylinder at high subcritical Reynolds number (4.3×104) has been studied, focusing on the characteristics of the vortex shedding phase drift and correlation along the cylinder span. Short time integration of the correlation coefficient, based on eight shedding cycles, showed that there were strong oscillations in the degree of correlation of the vortex shedding, and that these oscillations showed strong regularity having periods around 10–20 times the Strouhal period. These oscillations started when exceeding separations of Δz/d≊1 between the measurement points, and remained up to the largest case studied (Δz/d=6). The phase drift angle between two points at different spanwise positions was analyzed, showing that at the transition separation (Δz/d≊1) the probability distribution changed from being narrow banded to become more broad banded and closely Gaussian for an intermediate spacing of 2
Mesoscale Features Associated with Tropical Cyclone Formations in the Western North Pacific

Abstract The mesoscale features of 124 tropical cyclone formations in the western North Pacific Ocean during 1999–2004 are investigated through large-scale analyses, satellite infrared brightness temperature (TB), and Quick Scatterometer (QuikSCAT) oceanic wind data. Based on low-level wind flow and surge direction, the formation cases are classified into six synoptic patterns: easterly wave (EW), northeasterly flow (NE), coexistence of northeasterly and southwesterly flow (NE–SW), southwesterly flow (SW), monsoon confluence (MC), and monsoon shear (MS). Then the general convection characteristics and mesoscale convective system (MCS) activities associated with these formation cases are studied under this classification scheme. Convection processes in the EW cases are distinguished from the monsoon-related formations in that the convection is less deep and closer to the formation center. Five characteristic temporal evolutions of the deep convection are identified: (i) single convection event, (ii) two co.
Asymptotic estimates for symmetric vortex streets

Abstract Steady plane inviscid symmetric vortex streets are flows defined in the strip R × (0, b) and periodic in x with period 2a in which the flow in (−a, a) × (0, b) is irrotational outside a vortex core on which the vorticity takes a prescribed constant value. A family of such vortex street flows, characterised by a variational principle in which the area |Aα| and the centroid yc of the vortex core Aα are fixed, will be considered. For such a family, indexed by a parameter α, suppose that the cores Aα become small in the sense that Asymptotic estimates on functionals such as flux constant and speed are obtained.
Viscoplastic Modeling of Surface Relief Grating Growth on Isotropic and Preoriented Azopolymer Films

We report on solving of two intriguing issues concerning the inscription of surface relief gratings within azopolymer thin films under irradiation with SS, PP and RL interference patterns. For this, we utilize the orientation approach and viscoplastic modeling in combination with experimental results, where the change in surface topography is acquired in situ during irradiation with modulated light. First, the initial orientation state of polymer backbones is proved to be responsible for the contradictory experimental reports on the efficiency of the SS interference pattern. Different orientation states can influence not only the phase of SS grating but also its height, which is experimentally confirmed by using special pretreatments. Second, the faster growth of gratings inscribed by the RL interference pattern is shown to be promoted by a weak photosoftening effect. Overall, the modeled results are in good agreement with the order of relative growth efficiency: RL–PP–SS.
