The ISOPHOT 170 μm serendipity survey. III. FIR statistics of optically identified galaxies

Aims. To shed more light on the integrated FIR properties of galaxies, the ≈ 2000 compact sources in the ISOPHOT Serendipity Survey associated with identified galaxies are investigated statistically. They provide the only sample large enough to determine the FIR properties such as dust temperatures and masses, FIR luminosities, and HI-to-dust ratios not only for the group as a whole, but also divided into several subgroups of different Hubble types. Only with this catalog, the high flux end of the $\mathrm{170~{\mu}m}$ galaxy number counts can be established, which is crucial as a complement to the much deeper ISOPHOT studies at this wavelength in much smaller sky areas. Methods. The differential distributions of integrated FIR properties and the cumulative number counts are analysed. Results. The galaxy list of the ISOPHOT Serendipity Survey has a $\mathrm{170~{\mu}m}$ completeness limit of ≈ 2 Jy. The statistical analysis confirmed that the ${F_{170~{\mu}{\rm m}}} / {F_{100~{\mu}{\rm m}}}$ flux ratios peak at ≈ 1, corresponding to a dust color temperature of ≈ 20 K. FIR luminosities and dust masses cover a large range with peaks near $L{_\mathrm{1-1000} \approx 10^{10.5 \pm 1}\,L_{\odot}}$ and $M{_{\rm Dust} \approx 10^{7.5 \pm 0.5}~M_{\odot}}$, respectively. HI-to-dust ratios range from ≈ 10 and ≈ 10 4 , rendering the notion of fiducial HI-to-dust ratio for conversion between gas and dust masses almost useless. The latest models of the cumulative $\mathrm{170~{\mu}m}$ number counts are in reasonable agreement with the deep as well as the shallow surveys from ISO up to fluxes of ≈ 50 Jy.
Tauber theory for infinitely divisible variance functions

We study a notion of Tauber theory for infinitely divisible natural exponential families, showing that the variance function of the family is (bounded) regularly varying if and only if the canonical measure of the Levy-Khinchine representation of the family is (bounded) regularly varying. Here a variance function V is called bounded regularly varying if V(u) - c P either at zero or infinity, with a similar definition for measures. The main tool of the proof is classical Tauber theory.

The Use of Systemic Inflammatory Response Syndrome (SIRS) and Elevated Liver Enzymes as Predictive Factors of Gangrenous Cholecystitis: A Case Report

Gangrenous cholecystitis is a severe complication of acute cholecystitis. It is often found incidentally during laparoscopic cholecystectomy or during conversion to open surgery and diagnosed with subsequent pathological analysis. While intraoperative diagnosis is typically through direct visualization of the gallbladder, specific diagnostic modalities may guide physicians toward an earlier diagnosis. Surgical intervention and a more aggressive approach are often needed to prevent the advancement of the disease and its catastrophic complications. This case report illustrates the distinct risk factors predisposing a patient to develop gangrenous cholecystitis. Comorbidities such as hypertension, coronary artery disease, age, the relevance of the SIRS criteria, and elevated liver enzymes are explored as predictive factors in a patient with gangrenous cholecystitis.
The Trend of Omnichannel Trade Fairs. Are B2B Exhibitors Open to This Challenge? A Study on Portuguese Exhibitors

ABSTRACT Purpose Omnichannel is a trend also reaching events and their participants. So naturally, the trade fairs will be confronted with this reality of digital transformation. Given that exhibitors generally have the primacy of deciding to participate or not in a trade fair, this study aims to take this further, developing a representative model of exhibitors’ perception of an omnichannel trade fair. Design/methodology/approach This study used a quantitative approach through a survey. Structural equation modeling (SEM) was used on the data collected from 306 Portuguese B2B exhibitors. Within the SEM method, the multi-group causal analysis was also used to analyze the moderating role of the type of exhibitors (between industries and B2B service). Findings A new model is described, incorporating the causal relationships between exhibitors’ perceived compatibility with omnichannel trade fairs and consequent engagement and loyalty. The model reveals the exhibitors’ understanding of omnichannel compatibility with the trade fair’s context, positively influencing their engagement and loyalty. The results also reveal no significant differences between the types of exhibitors (industries and B2B service). Research implications Trade fairs continue to be excellent business-to-business (B2B) marketing tools, and the intensity of the use of digital technologies at events will lead to new challenges and opportunities. But few studies have investigated this topic. Thus, this research investigated the exhibitors’ perception of omnichannel trade fairs and their consequences on engagement and loyalty. Therefore, this research is a relevant contribution to the literature on B2B trade fairs and raises new research lights Practical implications The great differential of omnichannel is precisely in integrating online and offline channels. This positive opening of exhibitors to omnichannel trade fairs extends multiple opportunities and challenges for exhibitors, organizers, and visitors. “Omnicanalization” of trade fairs will imply a convergence strategy that integrates all connectivity channels between the three parties. Originality/value This study’s findings address the gap in trade fair literature concerning the lack of an omnichannel approach, which is a fresh and pertinent perspective.
Convergence Rates in Nonparametric Bayesian Density Estimation

We consider Bayesian density estimation for compactly supported densities using Bernstein mixtures of beta-densities equipped with a Dirichlet prior on the distribution function. We derive the rate of convergence for α-smooth densities for 0 < α ≤ 2 and show that a faster rate of convergence can be obtained by using fewer terms in the mixtures than proposed before. The Bayesian procedure adapts to the unknown value of α. The modified Bayesian procedure is rate-optimal if α is at most one. This result can be extended to two dimensions.
Error-Controlled Model Reduction in Flexible Multibody Dynamics

One important issue for the simulation of flexible multibody systems is the quality controlled reduction in the flexible bodies degrees of freedom. In this work, the procedure is based on knowledge about the error induced by model reduction. For modal reduction, no error bound is available. For Gramian matrix based reduction methods, analytical error bounds can be developed. However, due to numerical reasons, the dominant eigenvectors of the Gramian matrix have to be approximated. Within this paper, two different methods are presented for this purpose. For moment matching methods, the development of a priori error bounds is still an active field of research. In this paper, an error estimator based on a new second order adaptive global Arnoldi algorithm is introduced and further assists the user in the reduction process. We evaluate and compare those methods by reducing the flexible degrees of freedom of a rack used for active vibration damping of a scanning tunneling microscope.
A preliminary exploration of attitudes, beliefs, and barriers to physical therapists’ practices in ordering diagnostic imaging

BACKGROUND: Diagnostic imaging (DI) studies are useful resources for examining musculoskeletal (MSK) conditions. When DI is used appropriately, it is an important tool for physical therapists (PTs). OBJECTIVE: The purpose of this study was to explore the attitudes, beliefs, and barriers to PTs’ practices in referring to DI in Saudi Arabia (SA). METHODS: For this quantitative cross-sectional study, an online self-reported questionnaire was designed and distributed. A total of 138 PTs participated in the study. RESULTS: Although most PTs had access to DI, few reported being able to order DI. The PTs demonstrated positive attitudes regarding their ability to refer patients for DI. Nevertheless, some PTs have adopted several beliefs and awareness of PTs regarding the clinical appropriateness of referring to DI, which may increase the unnecessary utilisation of DI requests. More than half of the PTs in this study reported that they were unfamiliar with the clinical rules used for prescribing imaging. CONCLUSION: This study highlights recommendations to improve PTs’ practices towards DI in SA, such as providing more DI courses targeting PTs and including clinical rules within DI education in undergraduate studies. Furthermore, a clear governmental policy is needed to permit PTs to refer to DI when specific criteria are met.
Digit patterns and transcendental numbers

Abstract We use a theorem of Loxton and van der Poorten to prove the transcendence of certain real numbers defined by digit patterns. Among the results we prove are the following. If k is an integer at least 2, P is any nonzero pattern of digits base k, and counts the number of occurrences (mod r) of p in the base k representation of n, then is transcendental except when k = 3, P = 1 and r = 2. When (r, k − 1) = 1 the linear span of the numbers has infinite dimension over Q, where P ranges over all patterns base k without leading zeros.

Large and reversible elastocaloric effect in dual-phase Ni54Fe19Ga27 superelastic alloys

In this work, we report elastocaloric effect (eCE) in Ni-Fe-Ga polycrystalline alloys. By application of a uniaxial compressive stress of 170 MPa at 298 K, a large and recoverable temperature change of 4 K has been obtained in precipitates-containing Ni54Fe19Ga27 alloys. The degradation of eCE is insensitive to 100 loading-unloading cycles. In comparison, the loss of mechanical integrity occurs in the single-phase alloy suffering from only 10 superelastic cycles, implying a short fatigue life. Good mechanical properties, large and equivalent adiabatic temperature change (ΔT) under loading-unloading cycle render dual-phase Ni-Fe-Ga promising candidate materials for solid-state mechanical cooling application at ambient conditions.
Caste, gender, and intersectionality in stream choice: evidence from higher secondary education in India

ABSTRACT We investigate how social identity, namely gender and caste, affects stream choice at the higher secondary level of schooling in India. The choice of science stream at this level is a crucial determinant of subsequent science, technology, engineering, and mathematics (STEM) education and labor market outcomes. Using nationally representative data spanning a decade, we show that females and individuals from historically disadvantaged castes are significantly less likely to study science. We analyze the role of various socio-economic and schooling-related factors in explaining these gaps. We also highlight the interplay between caste and gender using an intersectionality framework.
International Politics and the Subnational Allocation of World Bank Development Projects

Temporary United Nations Security Council (UNSC) members receive more World Bank projects. I consider the potential for UNSC status to influence aid allocation within recipient countries. While strategically important recipients might gain greater discretion over the internal distribution of aid, no clear evidence establishes whether World Bank aid tends to succumb to political pressures within countries. I examine whether political favoritism within countries varies with UNSC status and find little evidence for a connection. While cross-national lending may follow politics, subnational allocation seems to be unrelated to international politics, which has important implications for the efficacy of Bank assistance.
Maternal and fetal risk factors for stillbirth in Otjozondjupa Region, Namibia: a case-control study

Introduction: stillbirth is defined as a baby born with no signs of life. Globally, around 3.2 million stillbirths occur annually, of which, 98% are experienced in low and middle-income countries. Otjozondjupa Region topped the list of regions with high burden of stillbirth in Namibia in 2016. This study sought to elucidate risk factors for stillbirth. Methods: an unmatched 1:2 case-control study was conducted. A sample of 285, 95 cases and 190 controls were chosen using simple random sampling method. Bivariate and multivariate analyses were done to assess the risk factors of stillbirth. Results: maternal medical and obstetric factors significantly associated with stillbirth are: premature delivery (aOR 0.13 95% CI 0.05, 0.33, P < 0.001), gestational age (aOR 0.04, 95% CI 0.00, 0.25, P < 0.001), high-risk pregnancy (aOR 3.59, 95% CI 1.35, 9.55, P = 0.01), duration of labor (aOR 4.04, 95% CI 1.56, 10.43, P = 0.003) and antenatal care (ANC) attendance (aOR 0.07, 95% CI 0.00, 0.79, P = 0.03). Only low birth weight (≤ 2500 g) was associated with stillbirth amongst fetal related factors (aOR 16.58, 95% CI 8.71, 31.55, P < 0.001). Conclusion: this study concludes that stillbirth in Otjozondjupa Region was mostly associated with maternal medical and obstetric factors. It also concluded that attending antenatal care in Otjozondjupa did not improve birth outcome.
Related Factors with Depression and Anxiety in Mastectomized Women Breast Cancer Survivors

Breast cancer (BC) is the most common cancer diagnosis with the highest mortality rate worldwide. The aim of this study was to identify factors related to depression and anxiety in mastectomized women BC survivors. A cross-sectional study was conducted with a sample of 198 women diagnosed with BC aged 30–80 years in Mexico. Depression and anxiety were assessed using the 14-item Hospital Anxiety and Depression Scale (HADS). The results showed that 94.44% and 69.18% of the women scored more than eight points on HADS in the anxiety and depression subscales, respectively; 70.20% and 10.60% were identified as pathological. The following variables were analyzed: age, time elapsed since the start of treatment, received treatment at the time of the evaluation, type of surgery, family history, marital status and employment status. Time elapsed since surgery, having a partner, and employment showed significant results as factors associated to levels of depression and anxiety in these patients. In conclusion, it has been shown that BCSs under 50 years of age receiving some kind of treatment, without family history, without a partner, with a job, with more than secondary education and with more than 5 years since diagnosis could have higher rates of clinical depression. On the other hand, BCSs older than 50 years receiving some kind of treatment, without family history, without a partner, with a job, with more than secondary education and with more than 5 years since diagnosis, could have higher rates of clinical anxiety. In conclusion, the variables studied provide valuable information for the implementation of psychotherapy plans in healthcare systems to reduce the risk of depression and/or anxiety in women with BC who have undergone mastectomy.
Relationships between Obesity and Incidence of Fractures in a Middle‐Aged Population: A Study from the CARTaGENE Cohort

The association between obesity and fracture risk is complex and may vary by definition of obesity, skeletal site, and sex. We aimed to evaluate the relationships between obesity, defined using body mass index (BMI) or waist circumference (WC), and fracture incidence at any site and by skeletal site (i.e., major osteoporotic fractures [MOFs], distal lower limb fractures [tibia, ankle, feet], and distal upper limb fractures [forearm/elbow, wrist]). The secondary aim was to assess the aforementioned relationships by sex. We used CARTaGENE, a large population‐based cohort of individuals aged 40–70 years from Quebec, Canada, who were assessed in 2009–2010. Incident fractures were identified via linkage with healthcare administrative databases over a 7‐year period. Cox proportional hazard models adjusted for several potential confounders were used to estimate the relationships, with exposures treated as continuous variables. Results are reported as adjusted hazard ratios (aHRs) and 95% confidence intervals. We identified 19 357 individuals (mean ± standard deviation: age 54 ± 8 years, BMI 27 ± 5 kg/m2, WC 94 ± 14 cm; 51.6% women). During follow‐up, 497 women and 323 men sustained a fracture. There was a linear relationship between fracture incidence and WC, while cubic splines best fitted the relationship for BMI. Greater WC was associated with an increased risk of fracture at the distal lower limbs in the whole cohort and in the subgroup of women: aHR for each 10 cm increased in WC of 1.12 (1.03, 1.21) and 1.12 (1.01, 1.24), respectively. In men, WC was not significantly associated with any fracture outcome. Higher BMI was also significantly associated with distal lower limb fracture risk in the whole cohort (p = 0.018). No significant relationships were found between either WC or BMI and the risk of any fracture, MOFs, and distal upper limb fractures. In middle‐aged individuals, obesity, and mainly abdominal obesity, was associated with distal lower limb fracture risk. © 2023 The Authors.

Fractionated electrograms from a computer model of heterogeneously uncoupled anisotropic ventricular myocardium.

BACKGROUND The relation between heterogeneously coupled myocardium and fractionated electrograms is incompletely understood. The purpose of this study was to use a detailed computer model of nonuniformly anisotropic myocardium to test the hypothesis that spatial variation of morphology of electrograms recorded simultaneously from multiple sites increases with increasing heterogeneity of intercellular coupling. METHODS AND RESULTS A sheet of elements with Beeler-Reuter ionic kinetics was coupled with cytoplasmic resistivity to model cells. Gap junctional resistance values were assigned by recursive randomization to produce a fractal pattern of heterogeneous coupling, simulating damage resulting from infarction. The correlation dimension of the pattern, D, measured heterogeneity of intercellular coupling. The peak-to-peak amplitude, duration, minimum derivative (steepest downslope), number of inflections, frequency of peak power, and bandwidth of unfiltered unipolar electrograms were calculated. Linear regressions indicate (P < .001) that the coefficient of variation of five electrogram metrics increases with increasing substrate heterogeneity and that the distance over which electrogram morphology decorrelates decreases with increasing heterogeneity of intercellular coupling. CONCLUSIONS These findings confirm our hypothesis that the spatial variation of morphology of electrograms recorded simultaneously from multiple sites increases with increasing heterogeneity of intercellular coupling.
Flat Cavity Expansion: Theoretical Model and Application to the Interpretation of the Flat Dilatometer Test

AbstractThis paper presents a theoretical model for flat cavity expansion in elastic soil. By using the conformal mapping method, the nonaxisymmetric boundary value problem of flat cavity expansion is transformed from the original physical plane into the axisymmetric boundary value problem in the phase plane, which results in a series of closed-form solutions for the stress and displacement induced by the flat cavity expansion. These closed-form solutions are then validated by FEM and provide the basis for the interpretation of the list-off pressure of the flat dilatometer test. Subsequently, a closed-form solution for the list-off pressure in the flat dilatometer test is given. The suitability of the solution for the list-off pressure is validated by comparing the predictions with a series of field test data provided by previous scholars. Good agreement is achieved. The proposed theoretical model improves on the previous empirical method for the interpretation of the list-off pressure in the flat dilatom.
Hodge-Newton filtrations, cell decomposition and cohomology of certain p-adic moduli spaces

In this thesis we study p-adic analytic geometry and l-adic cohomology of some Rapoport-Zink spaces, using the theory of Harder-Narasimhan filtration of finite flat group schemes developed by Fargues . This thesis consists of three parts. The first part deals with some non-basic Rapoport-Zink spaces, which satisfy the condition that their Newton polygon and Hodge polygon have a non-trivial contact point, which is a breakpoint for the Newton polygon. Under this hypothesis, we prove these Rapoport-Zink spaces can be decomposed as a direct sum of smaller Rapoport-Zink spaces associated to some suitable parabolic subgroups, thus their l-adic cohomology is parabolically induced and in particular contain no supercuspidal representations. We prove these facts by first proving a theorem about the Hodge-Newton filtration for p-divisible groups with additional structures over complete valuation rings of rank one and mixed characteristic (0,p). In the second part, we consider the basic Rapoport-Zink spaces with signature (1,n-1) for the unitary groups associated to the unramified quadratic extension of Qp. We study the Hecke action on these spaces in details. By using the theory of Harder-Narasimhan filtrations of finite flat group schemes, and the Bruhat-Tits stratification of the reduced special fiber Mred studied by Vollaard-Wedhorn, we find some compact analytic domain DK such that its translates under the group G(Qp)×Jb(Qp) form a locally finite cover of the whole space MK. We call such a phenomenon a locally finite cell decomposition.In the third part we prove a Lefschetz trace formula for these spaces for the action of regular semi-simple elliptic elements, by considering the action of these elements on the cells and applying Mieda's main theorem. In the same way we can also reprove the Lefschetz trace formula for Lubin-Tate spaces as previously obtained by Strauch and by Mieda. This Lefschetz trace formula should characterize the realization of local Jacquet-Langlands correspondences for unitary groups in the l-adic cohomology of these Rapoport-Zink spaces, as soon as some corresponding representation theoretic problems are solved.
Applications of Multigrid Software in the Atmospheric Sciences

Abstract Elliptic partial differential equations from different areas in the atmospheric sciences are easily and efficiently solved using the multigrid software package mudpack. It is shown that the multigrid method is more efficient than other commonly used methods, such as Gaussian elimination and fixed-grid relaxation. The efficiency relative to other methods, both in terms of computational time and storage requirement, increases rapidly with grid size.
