Early Detection of Myocardial Contusion and Its Outcomes in Patients with Blunt Chest Trauma

Background: Polytrauma has a significant impact on the wellbeing and provided healthcare for the populations. More than fifteen percent of emergency room admission worldwide are due to blunt chest trauma (BCT), which comes in second most common cause of death in vehicle collisions after head injuries. Exposure of anterior chest wall to an abrupt high-speed deceleration injury results in thorax compression, which is a common cause of BCT. The trauma may cause damage to all thoracic structures. Objective: In patients with acute chest injuries, the goal of this study was to identify the early onset of myocardial contusion and its consequences. Patients and methods: This study was carried out over the course of a year in the Emergency Department of the Mansoura University Hospital. The research comprised 153 individuals who presented with solitary BCT. Results: When compared to patients without myocardial contusions, the mean heart rate was statistically significantly greater in the cases with myocardial contusions. The global circumferential strains (GCS) and the mean arterial pressure (MAP) were statistically significantly lower in the cases with myocardial contusions as compared with the cases with no myocardial contusions. In patients with myocardial contusions, the length of hospital as well as the length of intensive care unit (ICU) stays were statistically significantly longer. Conclusion: The diagnosis of blunt chest trauma is exceedingly difficult since it can result in a broad variety of clinical manifestations and damage. Patients may arrive at the hospital with stable hemodynamics and no symptoms.
Left Atrial Wall Motion Velocity Assessed during Atrial Fibrillation Predicts Sinus Rhythm Maintenance after Electrical Cardioversion in Patients with Persistent Atrial Fibrillation

Reduced left atrial wall motion velocity measured during AF (LAWMV) indicates left atrial remodeling. The aim of this study was to investigate whether LAWMV assessed with tissue Doppler imaging during atrial fibrillation (AF) predicts sinus rhythm (SR) maintenance after direct current cardioversion (DCCV) for persistent AF. The study included 126 patients who underwent DCCV and were followed for 12 months. At 12 months, maintained SR was reported in 55 patients (43.7%). We noted that LAWMV was higher in patients with maintained SR at 12 months than in those with recurrent AF (3.69 ± 0.84 vs. 2.86 ± 1.09; p < 0.001). In the multivariable regression model containing echocardiographic variables, LAWMV was an independent predictor of SR maintenance at 12 months (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.1–2.69; p = 0.017). Similarly, LAWMW was an independent predictor of SR maintenance at 12 months (OR 1.81, 95% CI 1.19–2.77; p = 0.006) in the multivariate regression model containing both echocardiographic and clinical variables. LAWMV predicts SR maintenance after DCCV for persistent AF. Echocardiographic markers of left atrial mechanical remodeling are better at predicting SR maintenance than markers of structural remodeling.
Insufficient Physical Activity Is a Global Marker of Severity in Alcohol Use Disorder: Results from a Cross-Sectional Study in 382 Treatment-Seeking Patients

Improving physical activity (PA) in patients with alcohol use disorder (AUD) has recently emerged as an important component of the global treatment strategy to improve drinking outcomes and quality of life. However, this new approach should focus on AUD patients with insufficient baseline PA and requires this subgroup to be better characterized. In a population of 382 treatment-seeking AUD patients, PA was assessed using the International Physical Activity Questionnaire, and participants were divided into two groups: insufficient PA group and sufficient PA group. The severity of the AUD was assessed using the DSM-5 criteria, the Alcohol Use Disorder Identification Test, and the Severity of Alcohol Dependence Questionnaire. In logistic regression models, individuals with insufficient PA were more likely than other AUD individuals to present a higher Body Mass Index (p < 0.001), a higher number of AUD DSM-5 criteria (p < 0.05), more frequent opioid use (p < 0.05), higher scores at the Fagerström Test for Nicotine Dependence (p < 0.001), State-Trait Anxiety Inventory (p < 0.001), impulsivity scale (p < 0.05), Pittsburgh Sleep Quality Inventory (p < 0.05), and lower WHO Quality of Life (p < 0.001) scores. In AUD, an insufficient baseline PA is associated with several markers of severity, and physical exercise interventions should be part of a multimodal treatment program integrating the global impairments of patients.
Financial Inclusion Effect on Core Poverty During The Pandemic Period in East Java

Poverty is increasing globally at this time especially the impact of the Covid-19 pandemic. Meanwhile, the banking sector has a role to play in controlling the growing poverty, one of which is through financial inclusion. In some areas, the financial inclusion index has improved, indicated by the number of people who have switched from traditional savings to financial institution savings and have also reached the infrastructure of conventional commercial banks, but the fact has not yet reached the “usefulness of banking services”. So that financial inclusion is not really felt by the community. This study uses data from the March 2020 National Socio-Economic Survey (Susenas) and Podes 2020 to determine the effect of financial inclusion on core poverty. From the results of the logit regression estimation, it was found that financial inclusion had a strong effect on the status of core poverty in households when the COVID-19 pandemic hit in East Java (2020). Ownership of bank accounts has a strong and negative effect on poverty. The farther the distance to banking facilities, the greater the chance of experiencing poverty. Access to formal credit has the opportunity to move away from poverty. Education remains a key variable if you want to be free from poverty. The added value of farming households is still not optimal in increasing welfare, because they still have the opportunity to experience poverty. Access to information technology in households can increase opportunities to be more prosperous. From these results, the government should seek to increase public participation in having a bank account through banking literacy, through formal education, adding infrastructure for financial institutions evenly to villages, expanding access to formal credit services, and adding cellular/internet network infrastructure up to suburbs (rural/remote areas).
ANATOMY OF A SOLAR FLARE: MEASUREMENTS OF THE 2006 DECEMBER 14 X-CLASS FLARE WITH GONG, HINODE, AND RHESSI

Some of the most challenging observations to explain in the context of existing flare models are those related to the lower atmosphere and below the solar surface. Such observations, including changes in the photospheric magnetic field and seismic emission, indicate the poorly understood connections between energy release in the corona and its impact in the photosphere and the solar interior. Using data from Hinode, TRACE, RHESSI, and GONG we study the temporal and spatial evolution of the 2006 December 14 X-class flare in the chromosphere, photosphere, and the solar interior. We investigate the connections between the emission at various atmospheric depths, including acoustic signatures obtained by time–distance and holography methods from the GONG data. We report the horizontal displacements observed in the photosphere linked to the timing and locations of the acoustic signatures we believe to be associated with this flare, their vertical and horizontal displacement velocities, and their potential implications for current models of flare dynamics.
On Infinity Topoi

In this paper we investigate an infinitely categorical analogue of the theory of Grothendieck topoi. In particular, we define infinity topoi and prove an analogue of Giraud's theorem, expressing the equivalence of ``intrinsic'' and ``extrinsic'' definitions. We also discuss the relationship between the theory of infinity topoi and classical topics in homotopy theory and dimension theory.
Research on fundus image augmentation algorithm

Diabetic retinopathy is a serious ocular complication caused by diabetes, has now become the main reason for the workforce blinding, using digital fundus image for diabetic retinopathy screening regularly is the key to preventing blindness. However, in the process of image acquisition, generation and transmission, it is susceptible to low light conditions and Gaussian noise, and it is difficult to detect small lesions and blood vessels in fundus images, which greatly reduces the accuracy of computer-aided diagnosis. Therefore, this paper proposes an image enhancement algorithm for digital fundus images, using adaptive clipping based on improved Canny edge detection to perform square clipping around fundus region. The improved CLAHE technique was used for low light enhancement to highlight the details of the lesions in the image. Aiming at the additive white Gaussian noise caused by medical image digitalize process, the fundus image denoising algorithm based on self-supervised EM-GMM is used to suppress the influence of noise by imposing sparsity constraint on covariance eigenvalues. The experiment shows that our methods achieve good performance in DDR dataset.
RURAL LIVELIHOOD TRANSFORMATION AS AN EFFECT OF JATIGEDE DAM DEVELOPMENT IN SUMEDANG WEST JAVA

Jatigede dam development in Sumedang, West Java, was planned in the 1960s and facing a dynamic revolution in Indonesia’s Governmental System. The political shift causes a change in the government’s priority of development, and as a result, this project had been postponed for decades. In the 1980s, The Government had given land compensation to the rural householder who lives at the site plan. The long-postponed development execution makes rural people unaware to leave the site and continue living on the compensated land for generations. Then in 2012, Government decides to execute the development as a targeted Indonesian Economic Master Plan to boost economic growth. This sudden regulation causes shock and stress for rural people’s livelihood since they should change their way of living in a short time since access to resources became limited by inundation. However, the Dam development unavoidably causes rural transformation that has an impact on rural people’s livelihood. Rural Livelihood transformation can be seen in livelihood assets including natural, financial, physical, human, and social assets condition after the inundation. This paper aims to identify the condition of rural livelihood assets as an impact of rural transformation caused by Jatigede Dam development in Sumedang, West Java. Therefore, the study outcomes were determined as a recommendation for preventing vulnerability by implementing programs for the impacted rural household.
The X-ray structure and spectrum of NGC 6251

NGC 6251 has been observed in low-energy X-rays with the Position Sensitive Proportional Counter on board ROSAT. No X-ray emission is seen from the 4. '5 long radio jet of this galaxy, suggesting that the electron spectrum is cut off for electron energies greater than E max ≃10 12 eV, but a bright X-ray source is coincident with the center of the galaxy. Most of the counts in this source are in a component of small angular size, FWHM<4″, corresponding to a linear size less than 3 kpc, although there is evidence for the presence of a low surface brightness halo with FWHM∼3'. If this halo is thermal bremsstrahlung of gas near NGC 6251, this gas cannot confine the arcminute-scale radio jet by simple (static) gas pressure
On the equivalence of contact invariants in sutured Floer homology theories

We recently defined an invariant of contact manifolds with convex boundary in Kronheimer and Mrowka's sutured monopole Floer homology theory. Here, we prove that there is an isomorphism between sutured monopole Floer homology and sutured Heegaard Floer homology which identifies our invariant with the contact class defined by Honda, Kazez and Mati\'c in the latter theory. One consequence is that the Legendrian invariants in knot Floer homology behave functorially with respect to Lagrangian concordance. In particular, these invariants provide computable and effective obstructions to the existence of such concordances. Our work also provides the first proof which does not rely on the relative Giroux correspondence that the vanishing or non-vanishing of Honda, Kazez and Mati\'c's contact class is a well-defined invariant of contact manifolds.
Sparse Recovery with Oversampling Ratio Greater than One Half

s.t. ‖z‖0 ≤ s, where sensing matrix A ∈ Rm×N , sparse signal x ∈ R (‖x‖0 ≤ s), dummy variable z ∈ R , and measurement vector b = Ax ∈ R. Various algorithms have been developed to tackle (Px) or varieties of (Px) such as orthogonal matching pursuit [12], iterative hard thresholding [1], CoSaMP [11], hard thresholding pursuit [8], subspace pursuit [4], etc. Successful sparse recovery algorithms possess a list of properties [11] including minimal number of measurements required, adaptability to different sampling schemes, noise robusty, optimal error guarantees, and efficient computational resource usage. In this paper, however, we are interested in designing algorithms that can successfully solve (Px) with number m of measurements as small as possible. This leads to the solvability of `0 sparse recovery problem (Px) with respect to oversampling ratio ρ = s/m [5, 7]. Unfortunately, if we require (Px) to be solvable for ALL ‖x‖0 ≤ s, then there is a theoretic upper-bound for oversampling ratio ρ. which is stated in the following theorem:
The Weisfeiler-Lehman Method and Graph Isomorphism Testing

Properties of the `$k$-equivalent' graph families constructed in Cai, F\"{u}rer and Immerman, and Evdokimov and Ponomarenko are analysed relative the the recursive $k$-dim WL method. An extension to the recursive $k$-dim WL method is presented that is shown to efficiently characterise all such types of `counterexample' graphs, under certain assumptions. These assumptions are shown to hold in all known cases.
Residual nuclide formation in 206,207,208,nat-Pb and 209-Bi induced by 0.04-2.6 GeV Protons as well as in 56-Fe induced by 0.3-2.6 GeV Protons

This work is aimed at experimental determination of independent and cumulative yields of radioactive residual product nuclei in the intermediate energy proton-irradiated thin targets made of highly isotopic enriched and natural lead ( 206,207,208,nat Pb), bismuth ( 209 Bi), and highly isotopic enriched iron ( 56 Fe). 5972 independent and cumulative yields of radioactive residuals nuclei have been measured in 55 thin Pb and Bi targets irradiated by 0.04, 0.07, 0.10, 0.15, 0.25, 0.6, 0.8, 1.2, 1.4, 1.6, and 2.6GeV protons. Besides, 219 yields have been measured in 0.3, 0.5, 0.75, 1.0, 1.5, and 2.6GeV proton-irradiated Fe target. In both cases, the protons were extracted from the ITEP U-10 synchrotron. The measured data are compared with experimental results obtained elsewhere and with theoretical calculations by seven codes. The predictive power was found to be different for each of the codes tested, but was satisfactory on the whole in the case of spallation products. At the same time, none of the codes can describe well the product yields throughout the whole product mass range, and all codes must be further improved.
The Role of WeChat in Building Relationships amongst International Students

In recent decades, there has been an increase in studies on international students’ use of social media in their host countries. However, there has been limited investigation on how these students utilise social media to help them learn and adjust to their new surroundings. The purpose of this study is to find out how one group of Chinese international Students (CIS), utilised WeChat to support their living and study through building relationships amongst each other in New Zealand (NZ). Nine in-depth individual interviews were conducted focusing on critical incidents that these students experienced while studying in NZ. The analysis of these incidents yielded several themes. The findings identified that CIS used social media in many different ways but primarily to help them maintain and create social networks in their host country, construct and sustain community, and engage in peer interactions and collaborative learning. Overall, CIS frequently utilised WeChat for connecting with peers to cope with variety of issues, including emotional support, building a social network, an outlet to vent about stress, isolation and depression, amongst many others. This study highlights the importance of social media in creating a sustainable connection amongst peers that contributes to student wellbeing in the higher education sector.
The Prrx1eGFP Mouse Labels the Periosteum During Development and a Subpopulation of Osteogenic Periosteal Cells in the Adult

The identity of the cells that form the periosteum during development is controversial with current dogma suggesting these are derived from a Sox9‐positive progenitor. Herein, we characterize a newly created Prrx1eGFP reporter transgenic mouse line during limb formation and postnatally. Interestingly, in the embryo Prrx1eGFP‐labeled cells become restricted around the Sox9‐positive cartilage anlage without themselves becoming Sox9‐positive. In the adult, the Prrx1eGFP transgene live labels a subpopulation of cells within the periosteum that are enriched at specific sites, and this population is diminished in aged mice. The green fluorescent protein (GFP)‐labeled subpopulation can be isolated using fluorescence‐activated cell sorting (FACS) and represents approximately 8% of all isolated periosteal cells. The GFP‐labeled subpopulation is significantly more osteogenic than unlabeled, GFP‐negative periosteal cells. In addition, the osteogenic and chondrogenic capacity of periosteal cells in vitro can be extended with the addition of fibroblast growth factor (FGF) to the expansion media. We provide evidence to suggest that osteoblasts contributing to cortical bone formation in the embryo originate from Prrx1eGFP‐positive cells within the perichondrium, which possibly piggyback on invading vascular cells and secrete new bone matrix. In summary, the Prrx1eGFP mouse is a powerful tool to visualize and isolate periosteal cells and to quantify their properties in the embryo and adult. © 2022 The Authors.

Universality for polynomial invariants on ribbon graphs with flags

In this paper, we analyze the Bollobas and Riordan polynomial for ribbon graphs with ags introduced in arXiv:1301.1987(math.CO) and prove its universality. We also show that this polynomial can be dened on some equivalence classes of ribbon graphs involving ag moves and that the new polynomial is still universal on these classes.
Statistical techniques for big data analytics in IoT-enabled green supply chain management: a survey

: In the manufacturing operation, intelligent Supply Chain Management systems (SCMS) can improve the quality of products, reduce cost, and accelerate the decision making process. The incorporation of environmentally sustainable processes into SCMS minimizes the overall environmental impact which is the target of Green Supply Chain Management (GSCM). The intelligence of the GSCM systems makes the business smarter. For this reason, it is always a concern to utilize cutting-edge ideas and technologies to optimize the operation of these systems. Internet of Things (IoT) is a promising Information technological concept that allows environmental objects to communicate with each other automatically and without human intervention. IoT is one of the most important IT solutions that provides intelligence and sustainability to GSCM systems. The significant feature of IoT is the huge volumes of data, called „big data‟ generated by the IoT sensors, installed on the different entities of the chain. To this end, big data processing in real time is a need for decision makers to preserve their companies‟ competitive advantage. There are many big data analytics techniques in the literature to target this issue. Our work will focus on surveying the statistical techniques that can be used in the analysis of big data generated from the IoT sensors situated on the different parts of GSCM to improve its performance, flexibility, productivity, and optimization of its resources through the effective analysis of the large amounts of raw data involved in IoT enabled GSCM, We will also uncover the best tools that can be used for this purpose.
Multivariate central limit theorems for Rademacher functionals with applications

Quantitative multivariate central limit theorems for general functionals of possibly non-symmetric and non-homogeneous infinite Rademacher sequences are proved by combining discrete Malliavin calculus with the smart path method for normal approximation. In particular, a discrete multivariate second-order Poincar\'e inequality is developed. As a first application, the normal approximation of vectors of subgraph counting statistics in the Erd\H{o}s-R\'enyi random graph is considered. In this context, we further specialize to the normal approximation of vectors of vertex degrees. In a second application we prove a quantitative multivariate central limit theorem for vectors of intrinsic volumes induced by random cubical complexes.
The Strong Small Index Property for Free Homogeneous Structures

We show that in algebraically locally finite countable homogeneous structures with a free stationary independence relation the small index property implies the strong small index property. We use this and the main result of [15] to deduce that countable free homogeneous structures in a locally finite relational language have the strong small index property. We also exhibit new continuum sized classes of $\aleph_0$-categorical structures with the strong small index property whose automorphism groups are pairwise non-isomorphic.
Electric load model synthesis by diffusion approximation of a high-order hybrid-state stochastic system

A statistical approach is used to model the dynamics of the electric demand of large aggregates of electric space heaters or air conditioners. The importance of such loads is twofold. First, they account for a significant portion of power system dynamics following a power outage. Second, because they are associated with energy storage, they are often selected for load shedding within a load management program. The derivation of the aggregate electrical dynamics is considered first for a homogeneous group of devices. Subsequently, a perturbation analysis yields the dynamics for a nonhomogeneous group. The homogeneons group aggregrate load model is a system of coupled ordinary, and partial differential equations (Fokker-Planck equations). It is obtained by writing evolution equations for the probability density of a hybrid-state Markov system used to model the switching dynamics of individual devices. This result is new and could give a clue to the analysis of a broad class of hybrid-state stochastic systems. In turn, this could provide a new impetus not only in the area of electric load modeling but other areas such as power system reliability and the design of relay control systems, where stochastic hybrid-state models occur frequently. Simulation results which illustrate the dynamical properties of the model are presented.
