The Relationship Between Interleukin 6 Level and Short Term Outcome in Atrial Fibrillation Subtypes a Case Control Study.

Background : Atrial fi brillation (AF) is the most common arrhythmia; at least more than two million individuals suffer from AF in the United States alone. AF is associated with high disease morbidity, mortality, a higher risk of stroke and thromboembolism. There are limited data on the role of Interleukin 6 (IL-6) as a prognostic factor in atrial fibrillation. So, we aimed to assess Interleukin 6(IL-6) level in AF subtypes and identify the relationship between IL 6 level, and short-term outcomes in AF. Results: Our results included three groups paroxysmal AF (19 cases), persistent AF (19 cases)
The characteristic and seasonal variation of mesoscale convective systems' precipitation over North China

Using an iterative rain‐cell tracking method to identify and track mesoscale convective system (MCS) precipitation during the warm seasons (May–October) of 2015–2020, we reveal the seasonal variation in the spatiotemporal distribution, rainfall characteristics, and the life cycle of MCS precipitation in different months over North China. Notable MCS precipitation centers are located around mountain slopes and downstream areas. The diurnal peak of MCS rainfall is manifested as a southeastern delay from afternoon in mountainous regions to midnight or morning over downstream plains. In May and June, MCS rainfall is distributed on the hillside of Taihang–Yan mountains and the Shandong Peninsula. MCS precipitation gets an early evening peak on mountain slopes and a nocturnal maximum over the North China Plain (NCP). In July and August, the MCS activities extend to NCP, and another MCS precipitation center exists over the Luliang Mountains in western North China, under the seasonal march of the monsoon flow. The local diurnal peaks to the east of 114°E are generally later than in May and June, and MCS precipitation gets a peak during midnight to early morning over the NCP. MCSs in July and August feature the strongest intensity. In September and October, the MCS precipitation shifts to high terrain of the Taihang Mountains and its west, with an early afternoon peak. MCSs have the largest size and the fastest propagation speed in September and October, but with the weakest intensity. Compared with short‐lived MCSs, long‐lived MCSs have stronger precipitation intensity, larger rainfall area, and faster propagation speed. In addition, the life cycle of long‐lived MCS precipitation represents asymmetric development and decay. Long‐lived MCSs occur with more pronounced upper troposphere warming and low‐level anomalous southwesterlies. Meanwhile, higher specific humidity in the low‐ and mid‐level troposphere provides a more favorable environment for the maintenance of MCS precipitation.
Snake Eyes. A Natural History of Picturing, Perception, and the Serpents That Lurk Within

Snakes capture us like no other creature. As serpents, dragons, and ouroboroi, their potency as symbols complicates their objective portrayal. Meanwhile, research suggests that serpentine shapes are present as ciphers within our visual circuitry before we ever even see them. From traditions of natural history to present-day neurobiology, there may be no way to depict snakes that is not also deeply imaginary. Résumé Les serpents nous captivent comme aucune autre créature. En tant que serpents, dragons et ouroboros, leur puissance symbolique complexifie leur représentation objective. Parallèlement, les recherches suggèrent que les formes serpentines sont présentes sous forme codée dans nos circuits visuels avant même que nous les percevions. Des traditions de l'histoire naturelle à la neurobiologie actuelle, il n'y a peut-être aucune façon de représenter les serpents qui ne soit profondément imaginaire.
Distributed polar-coded OFDM based on Plotkin’s construction for half duplex wireless communication

ABSTRACT A Plotkin-based polar-coded orthogonal frequency division multiplexing (P-PC-OFDM) scheme is proposed and its bit error rate (BER) performance over additive white gaussian noise (AWGN), frequency selective Rayleigh, Rician and Nakagami-m fading channels has been evaluated. The considered Plotkin’s construction possesses a parallel split in its structure, which motivated us to extend the proposed P-PC-OFDM scheme in a coded cooperative scenario. As the relay’s effective collaboration has always been pivotal in the design of cooperative communication therefore, an efficient selection criterion for choosing the information bits has been inculcated at the relay node. To assess the BER performance of the proposed cooperative scheme, we have also upgraded conventional polar-coded cooperative scheme in the context of OFDM as an appropriate bench marker. The Monte Carlo simulated results revealed that the proposed Plotkin-based polar-coded cooperative OFDM scheme convincingly outperforms the conventional polar-coded cooperative OFDM scheme by 0.5 ~ 0.6 dBs over AWGN channel. This prominent gain in BER performance is made possible due to the bit-selection criteria and the joint successive cancellation decoding adopted at the relay and the destination nodes, respectively. Furthermore, the proposed coded cooperative schemes outperform their corresponding non-cooperative schemes by a gain of 1 dB under an identical condition.
COINCIDENCE THEOREMS FOR COMPARABLE GENERALIZED NON LINEAR CONTRACTIONS IN ORDERED PARTIAL METRIC SPACES

In this paper, we prove some coincidence point theorems in-volving ϕ -contraction in ordered partial metric spaces. We also extend newly introduced notion of g -comparability of a pair of maps for linear contraction in ordered metric spaces to non-linear contraction in ordered partial metric spaces. Thus, our results extend, modify and generalize some recent well known coincidence point theorems of ordered metric spaces.
Resilient Dynamic State Estimation for Multi-Machine Power System With Partial Missing Measurements

Accurate tracking the dynamics of power system plays a significant role in its reliability, resilience and security. To achieve the reliable and precise estimation results, many advanced estimation methods have been developed. However, most of them are aiming at filtering the measurement noise, while the adverse affect of partial measurement missing is rarely taken into account. To deal with this issue, a discrete distribution in the interval [0,1] is introduced to depict mechanism of partial measurement data loss that caused by the sensor failure. Then, a resilient fault tolerant extended Kalman filter (FTEKF) is designed in the recursive filter framework. Eventually, extensive simulations are carried on the different scale test systems. Numerical experimental results illustrate that the resilience and robustness of the proposed fault tolerant EKF method against partial measurement data loss.
Wearable sensor to assess physiological responses and recovery to workplace violence

Repeated exposure to acute occupational stressors and violence poses significant mental and physical risks to workers. However, current methods for assessing the impact of these stressors, such as subjective self-reports and single-modal wearable technologies, do not capture continuous physiological and psychological responses to workplace stressors. To address this issue, we developed a multi-modal wearable armband that can non-invasively monitor physiological signals without interfering with work requirements. The armband can continuously record electrocardiogram, photoplethysmography, activity levels, and pulse transit time (PTT) - a biomarker of cuffless blood pressure. We conducted a study with sixteen nurses working 12-hour shifts at Intensive Care Unit, where they reported incidents of violence while wearing the armband for seven consecutive days. We analyzed the ratio of low- and high-frequency components of inter-beat-intervals of heart beats (LF/HF ratio) and PTT for one hour before and after the incidents to capture physiological responses and recovery patterns. Our results showed that the LF/HF ratio increased after the incident occurrence and reached baseline within 30 minutes, while the PTT decreased and persisted for more than an hour. This finding suggests that PTT can be a reliable biomarker for stress recovery. Continuous PTT measurement can be used to optimize individual and team performances based on recovery patterns in demanding work environments. In summary, our study highlights the importance of continuous physiological monitoring in assessing the impact of workplace stressors and provides a new method for measuring stress recovery using PTT.
Cubic rank transmuted distributions: inferential issues and applications

ABSTRACT In this paper, we introduce a new family of transmuted distributions, the cubic rank transmutation map distribution. This new proposal increases the flexibility of the transmuted distributions enabling the modelling of more complex data such as ones possessing bimodal hazard rates. In order to illustrate the usefulness of the cubic rank transmutation map, we use two well-known lifetime distributions, namely the Weibull and log-logistic models. Several mathematical properties of these new distributions, namely the cubic rank transmuted Weibull distribution and the cubic rank transmuted log-logistic distribution, are derived. Then, the maximum likelihood estimation of the model parameters is described. A simulation study designed to assess the properties of this estimation procedure is then carried out. Finally, applications of the proposed models and their fit are illustrated with some datasets and the corresponding diagnostic analyses are also provided.
An Evaluation of the Arabic Language Textbook for First Grade From the Teachers’ Point of View

The main purpose of this study is to evaluate the Palestinian Arabic Language Textbook, “Our Beautiful Language,” for first grade from the viewpoint of the teachers. The study also identified the significance of evaluating textbooks. For this purpose, a mixed methods research design was used to measure the extent to which the Palestinian Arabic language textbook meets the characteristics of a good textbook from the point of view of the teachers of Arabic language for the first grade of primary public schools. This method allows us to collect both quantitative (survey) and qualitative data (interview) data. According to the research results, the textbook still has a specific weakness and deficiency in the psycho-cognitive dimension despite the Palestinian Ministry of Education’s efforts to develop the curriculum. To improve textbooks through a national reform strategy, they must be freed from the constraints to which they are currently subject. To accomplish this, it is necessary to adopt the high standards for content creation established by textbook research centers.
A novel approach for coordinated design of TCSC controller and PSS for improving dynamic stability in power systems

The purpose of this article is to present a novel strategy for the coordinated design of the Thyristor Controlled Series Compensator (TCSC) controller and the Power System Stabilizer (PSS). A time domain objective function that is based on an optimization problem has been defined. This objective function takes into account not only the influence that disturbances have on the mechanical power, but also, and this is more accurately the case, the impact that disturbances have on the reference voltage. When the objective function is minimized, potential disturbances are quickly mitigated, and the deviation of the speed of the generator's rotor is limited; as a result, the system's stability is ultimately improved. Particle Swarm Optimization (PSO) and the Shuffled Frog Leaping Algorithm are both components of a composite strategy that is utilized in the process of determining the optimal controller parameters. (SFLA). An independent controller design as well as a collaborative controller design utilizing PSS and TCSC are developed, which enables a direct evaluation of the functions performed by each. The presentation of the eigenvalue analysis and the findings of the nonlinear simulation can help to provide a better understanding of the efficacy of the outcomes. The findings indicate that the coordinated design is able to successfully damp low-frequency oscillations that are caused by a variety of disturbances, such as changes in the mechanical power input and the setting of the reference voltage, and significantly enhance system stability in power systems that are connected weekly.
An efficient algorithm for unequal area facilities layout planning with input and output points

ABSTRACT The facility layout problem is to determine a layout design of facilities so as to minimize a total material handling cost (TMHC). In this paper, unequal area rectangular facilities with fixed dimensions are considered. Each of them has an input and output (I/O) points which can be located within or on the boundaries of facility. On the continual plane, facilities must be placed without overlaps. A two-heuristic algorithm is proposed to deal with this kind of problem. The first step is based on a construction method which places facilities sequentially. A median method is modified to set the position of facility. The second step improves a result of the first step. A facility group which can be moved horizontally or vertically without incurring an overlap is constituted and a group movement is done when it reduces a TMHC. Computational experiments show the proposed algorithm produces comparable quality of layouts to previous research within much shorter time.
Estimation of Static Young Modulus for the Third section in Zubair Oil Field :A Comparison Study

A detailed analysis for the mechanical properties of the rock is necessary to maintain a well bore and avoid problems with well bore instability. Static young's modulus is one of the most crucial rock mechanical properties utilized in the drilling process to assess wellbore integrity and setting-up geomechanical earth model. Static young’s modulus change with varies of formation lithology’s which arise the critical need for estimation. The current study, a static young modulus values of different formations in section 12.25“in Zubair oil field are determined by depending on correlation to indicate variations in units and layers. Data of Gamma ray (GR), density log, sonic compression log (DTCO), and sonic shear log (DTSM) logs of well ZA-2 are utilized to estimate this attribute. Four different correlations that are set-up in Techlog 2015 software are used to achieve the aim of this study. These outcomes are calibrated using the fundamental laboratory tests (Brazilin and Triaxle test). The results showed that the modified Morales correlation provides a good matching with Calibration data, while four key data points are poorly correlated with the results of John Fuller's analysis.Also, Morales correlation shows unconformity when porosity reduced by less than 10% at different intervals, and Plumb Bradford correlation produces incorrect findings of static young’s higher than the dynamic. The results declare inversely relationship between porosity and young’s modulus.
COVID-19 Vaccine Hesitancy among Perinatal Women

The impacts of Coronavirus (COVID-19) on reproductive health are detrimental. COVID-19 vaccine is recommended for pregnant women to prevent infection and its sequelae [1]. Vaccine uptake among pregnant women is generally low. Our study aimed to explore views, predictors and uptake of the COVID-19 vaccine among perinatal women & explore the reasons and concerns for declining it. A prospective cross-sectional muti-centred study was conducted from 1st November 2021 to 31st March 2022. It included 364 perinatal women through convenience sampling. The data was analyzed with Microsoft Excel & SPSS version 28.0 along with thematic analysis. A reasonable number of patients were doubtful about the safety (
Gyrokinetic analysis of low-n shear Alfvén and ion sound wave spectra in a high-beta tokamak plasma

Using the linear gyrokinetic code LIGKA, we study the structure of the continuous spectra Ω(ρ)=ω(ρ)+iγ(ρ) of shear Alfvén waves (SAW) and ion sound waves (ISW) in a high-beta JT-60U tokamak plasma and look for evidence of Alfvén acoustic couplings or mode conversion. Here, Ω is the complex local eigenfrequency, ρ is a radial coordinate, and we consider waves with low toroidal mode number n=3. We focus on the frequency range ωBAE≲ω≲ωTAE between the beta-induced and toroidicity-induced Alfvén frequency gaps. The real frequencies ω(ρ) of the gyrokinetic ISW continua are remarkably similar to MHD results. The kinetic damping rates are of order −γ/ω∼30% for Te/Ti≈1.7, and reduce to 15% when the temperature ratio is raised to Te/Ti≈4.8. It is shown that SAW and ISW continua can be simultaneously excited with an antenna and that the global response of the ISWs is significantly enhanced when the on-axis beta value is raised from β0=1.7% to 3.6% while keeping 1$ ? >Te/Ti>1. In contrast, when the ion temperature is increased such that Te/Ti≈0.4, ISW branches become undetectable in spite of higher β0. At the same time, a large part of the SAW continuum is locally destabilized by ion temperature gradients and a set of discrete global modes was found, some of which are weakly damped or unstable and interpreted as kinetic beta-induced Alfvén eigenmodes. It is estimated that the kinetic damping of such low-n Alfvénic modes contributes much more to the anomalous bulk ion heating than the excitation of nearby ISW continua, so that Alfvén acoustic couplings in the frequency band ωBAE≲ω≲ωTAE are irrelevant within the scope of the model used.
GC/MS Profiling of Becium grandiflorum Essential Oil and Evaluation of Its Antiviral Activity

Genus Becium of the Lamiaceae family encounters numerous medicinally and economically valued aromatic plants. The hydrodistilled essential oil of Becium grandiflorum (Lam.) Pic. Serm. aerial part was analyzed using GC/MS. A total of 32 compounds amounting to 99.68% of the essential oil were identified. Oxygenated diterpenes constituted the largest share (43.45%) in the studied oil followed by sesquiterpenes hydrocarbons (34.24%). Pimara-7,15-dien-3-ol (20.58%), 3-α -hydroxymanool (14.07%), caryophyllene (8.17%), sandaracopimaradiene (7.98%), Selina-3,7 (11)-diene (5.61%), and germacrene D (4.95%) are the chief identified compounds in B. grandiflorum essential oil. The essential oil was assessed for its antiviral potential against herpes simplex virus 1 (HSV-1) at a non-cytotoxic concentration using a cytopathic effect (CPE) inhibition assay on the Vero cell line. B. grandiflorum essential oil exhibited a pronounced in vitro cytotoxicity against Vero cells with 50 % cytotoxic concentration (CC 50 ) of 7.75 ± 0.84 µg/mL and weak anti-HSV-1 potency with percent inhibition of 21.36 ± 2.13 at a maximum non-toxic concentration of 1 µg/mL.
Concepts first: A course with improved educational outcomes and parity for underrepresented minority groups

Two active learning physics courses were taught and compared. The “concepts first” course was organized to teach only concepts in the first part of the class, the ultimate goal being to increase students' problem-solving abilities much later in the class. The other course was taught in the same quarter by the same instructor using the same curricular materials, but covered material in the standard (chapter-by-chapter) order. After accounting for incoming student characteristics, students from the concepts-first course scored significantly better in two outcome measures: their grade on the final exam and the grade received in their subsequent physics course. Moreover, in the concepts-first class course, students from groups underrepresented in physics had final exam scores and class grades that were indistinguishable from other students. Finally, students who took at least one concepts-first course in introductory physics were found to have significantly higher rates of graduation with a STEM major than st.
Hypoelliptic diffusion and human vision: a semi-discrete new twist on the Petitot theory

This paper is devoted to present an algorithm implementing the theory of neurogeometry of vision, described by Jean Petitot in his book. We propose a new ingredient, namely working on the group of translations and discrete rotations SE(2,N). We focus on the theoretical and numerical aspects of integration of an hypoelliptic diffusion equation on this group. Our main tool is the generalized Fourier transform. We provide a complete numerical algorithm, fully parallellizable. The main objective is the validation of the neurobiological model.

Boundary Layer Diabatic Processes, the Virtual Effect, and Convective Self‐Aggregation

The atmosphere can self‐organize into long‐lasting large‐scale overturning circulations over an ocean surface with uniform temperature. This phenomenon is referred to as convective self‐aggregation and has been argued to be important for tropical weather and climate systems. Here we present a boundary layer centric framework based on the available potential energy budget of convective self‐aggregation. We show that boundary layer diabatic processes dominate the available potential energy production and are, therefore, essential to convective self‐aggregation. We further show that the enhanced virtual effect of water vapor can lead to convective self‐aggregation.
Youth loneliness in pandemic times: a qualitative study in Quebec and Ontario

ABSTRACT In many countries, young adults have been the age group most affected by loneliness during the pandemic. While this phenomenon is now well quantified, we still lack a clear understanding of its causes, as well as of the main characteristics of this youth loneliness. We argue that a qualitative approach can help to capture the dynamics of youth loneliness during the pandemic: drawing on 48 life stories of young adults aged 18 to 30 conducted in 2020 and 2021 in Québec and Ontario, we identify the different hardships, emotions and coping strategies associated with loneliness. We show that beyond a common « shock of loneliness », this experience is associated with three main narratives -loneliness as an « abyss », a « battle » or a « resource »-, which sheds light on a process of « cumulative loneliness », affecting particularly the most vulnerable young people. The conclusion highlights some key lessons for research on youth loneliness.
Propofol in ICU Settings: Understanding and Managing Anti-Arrhythmic, Pro-Arrhythmic Effects, and Propofol Infusion Syndrome

Propofol has revolutionized anesthesia and intensive care medicine owing to its favorable pharmacokinetic characteristics, fast onset, and short duration of action. This drug has been shown to be remarkably effective in numerous clinical scenarios. In addition, propofol has maintained an overwhelmingly favorable safety profile; however, it has been associated with both antiarrhythmic and proarrhythmic effects. This review concisely summarizes the dual arrhythmic cardiovascular effects of propofol and a rare but serious complication, propofol infusion syndrome (PRIS). We also discuss the need for careful patient evaluation, compliance with recommended infusion rates, and vigilant monitoring.
