Background: Placenta accreta spectrum (PAS) is a clinical term used to describe the abnormal trophoblast invasion into the myometrium of the uterine wall and may enter into the serosa or even into adjacent organs. It is associated with severe obstetric haemorrhage and often requires emergency hysterectomy, which is one of the foremost causes of maternal morbidity and mortality. The vast of these conditions are seen in women with a history of previous caesarean section and placenta previa. Cases: In this study we present two cases of a rare type of PAS, placenta percreta, in women with a history of previous caesarean section (CS). Both instances were diagnosed prenatally, using the method of ultrasound and magnetic resonance imaging. They were scheduled for deliveries by CS, and both were hysterectomized. These diagnoses were confirmed in histopathological findings. Conclusion: Considering sparse published data and absence of well conducted studies, optimal management is still undefined. Caesarean hysterectomy is still the gold standard treatment for placenta accreta spectrum proposed by many societies as an absolute and final treatment.

Background: The aim of this study was to show the frequency and epidemiological characteristics of pregnant women who tested positive for SARS-CoV-2 during childbirth as well as the course, mode and outcome of their newborn treatment and diet after discharge. The aim is also to show individual symptoms developed by newborn from pregnant women who test positive for SARS-CoV-2. Method: The study included all the infants born to the pregnant women who tested positive for SARS-CoV-2 on a PCR test 24 hours prior to delivery or, had already been confirmed positive for the infection and had developed symptoms of the virus or had started treatment for SARS-CoV-2 several days prior to delivery. Results: 43/3237 (1.32%) of the pregnant women tested positive for the SARS-CoV-2 virus or had been infected prior to admission and were positive during delivery. A total of 45 newborn infants were transferred to a special room for the care of newborn infants born to SARS-CoV-2-positive mothers at the Department of Neonatology. Specifically, 30/45 (66.7%) of the newborn infants developed symptoms within the first hours of birth which withdrew spontaneously within 24–48 hours after birth. The symptoms referred to are not specific forSARS-CoV-2 infection and are not particularly indicative of infection. Conclusions: The conclusion of this short 21-month study is that prenatal and postnatal duration and outcome in infants is not aggravated by pregnant women who tested positive for SARS-CoV-2. Despite the individual symptoms described above and the pathological states the children developed during hospitalization, all the newborn infants were discharged from hospital in full health, and they were all breastfeeding following discharge in conditions which respected all the epidemiological preventive measures.

The efficiency of transport companies is a very important factor for the companies themselves, as well as for the entire economic system. The main goal of this paper is to develop an integrated model for determining the efficiency of representative transport companies over a period of eight years. An original model was developed that includes the integration of DEA (Data Envelopment Analysis), PCA (Principal Component Analysis), CRITIC (Criteria Importance Through Inter criteria Correlatio), Entropy and MARCOS (Measurement Alternatives and Ranking according to the COmpromise Solution) methods in order to determine the final efficiency of transport companies based on 10 input–output parameters. The results showed that the most efficient business performance was achieved in the period 2014–2017, followed by slightly less efficient results. Then, extensive sensitivity analysis and comparative analysis were performed, which confirmed, to some extent, the previously obtained results. In the sensitivity analysis, 30 scenarios with changes in the weights of criteria were created, while the comparative analysis was carried out with three other MCDM (Multi-Criteria Decision-Making) methods. Finally, the rank correlation index was determined using the Spearman and WS (Wojciech Salabun) correlation coefficients. According to the final results, very efficient years can be separated that can be the benchmark for furthering the business.

ABSTRACT Numerical modeling of detonation by the Wood-Kirkwood detonation theory requires the detonation front curvature radius to be specified as an input parameter. In this work we present two empirical equations for the estimation of the curvature radii of various explosives. The equations are derived based on a large number of literature-reported experimental data on the detonation front curvature radii as a function of charge radii and failure radii. The proposed equations predict the front curvature radii with the root mean square error of about 30%, which is a significant improvement compared to previously proposed empirical equations.

Trauma is the leading cause of pediatric mortality and abdominal injury is a significant contributor to morbidity. Abdominal trauma in the population of injured children, is the third leading cause of death in this population, after head and thoracic injuries. It is the most common cause of death owing to unrecognized injury. They most often occur in traffic accidents, games and sports. The clinical presentation depends on the severity of the injury, the injured organ and the associated injuries. Mesenteric injury from blunt abdominal trauma is uncommon and can be difficult to diagnose. It is known that seatbelt trauma from motor vehicle accidents is the most common mechanism of mesenteric injury and that the mesentery of the small bowel is injured more frequently than that of the colon. We present an unusual case, a seven-year-old boy who was injured while skiing. The patient was in a state of hemorrhagic shock and underwent emergency surgery after an urgent diagnosis. During the operation, the leading trauma and the reason for the hemorrhagic shock were found to be a mesenteric injury, and bleeding from the branches of the superior mesenteric artery. Early transport, monitoring and diagnostics significantly contribute to reducing morbidity and mortality. The standard in surgery is non-operative treatment of injured parenchymal organs. A multidisciplinary approach that includes doctors of various specialties (pediatric surgeons, pediatricians, neurosurgeons, anesthesiologists and radiologists) who contribute to the diagnosis and treatment of injured children through diagnostic and therapeutic procedures has a key role. At the end, the decision regarding surgical treatment is responsibility of pediatric surgeon.

The increasing availability of high-quality genome assemblies raised interest in the characterization of genomic architecture. Major architectural elements, such as common repeats and segmental duplications (SDs), increase genome plasticity that stimulates further evolution by changing the genomic structure and inventing new genes. Optimal computation of SDs within a genome requires quadratic-time local alignment algorithms that are impractical due to the size of most genomes. Additionally, to perform evolutionary analysis, one needs to characterize SDs in multiple genomes and find relations between those SDs and unique (non-duplicated) segments in other genomes. A naïve approach consisting of multiple sequence alignment would make the optimal solution to this problem even more impractical. Thus there is a need for fast and accurate algorithms to characterize SD structure in multiple genome assemblies to better understand the evolutionary forces that shaped the genomes of today. Here we introduce a new approach, BISER, to quickly detect SDs in multiple genomes and identify elementary SDs and core duplicons that drive the formation of such SDs. BISER improves earlier tools by (i) scaling the detection of SDs with low homology to multiple genomes while introducing further 7–33×\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$\times$$\end{document} speed-ups over the existing tools, and by (ii) characterizing elementary SDs and detecting core duplicons to help trace the evolutionary history of duplications to as far as 300 million years. BISER is implemented in Seq programming language and is publicly available at https://github.com/0xTCG/biser.

Purpose This paper aims to address the user perspective about usability, security and use of five authentication schemes (text and graphical passwords, biometrics and hardware tokens) from a population not covered previously in the literature. Additionally, this paper explores the criteria users apply in creating their text passwords. Design/methodology/approach An online survey study was performed in spring 2019 with university students in Mexico and Bosnia and Herzegovina. A total of 197 responses were collected. Findings Fingerprint-based authentication was most frequently perceived as usable and secure. However, text passwords were the predominantly used method for unlocking computer devices. The participants preferred to apply personal criteria for creating text passwords, which, interestingly, coincided with the general password guidelines, e.g. length, combining letters and special characters. Originality/value Research on young adults’ perceptions of different authentication methods is driven by the increasing frequency and sophistication of security breaches, as well as their significant consequences. This study provided insight into the commonly used authentication methods among youth from two geographic locations, which have not been accounted for previously.

Background The objectives of the study were to investigate the organizational characteristics of acute care facilities worldwide in preventing and managing infections in surgery; assess participants’ perception regarding infection prevention and control (IPC) measures, antibiotic prescribing practices, and source control; describe awareness about the global burden of antimicrobial resistance (AMR) and IPC measures; and determine the role of the Coronavirus Disease 2019 pandemic on said awareness. Methods A cross-sectional web-based survey was conducted contacting 1432 health care workers (HCWs) belonging to a mailing list provided by the Global Alliance for Infections in Surgery. The self-administered questionnaire was developed by a multidisciplinary team. The survey was open from May 22, 2021, and June 22, 2021. Three reminders were sent, after 7, 14, and 21 days. Results Three hundred four respondents from 72 countries returned a questionnaire, with an overall response rate of 21.2%. Respectively, 90.4% and 68.8% of participants stated their hospital had a multidisciplinary IPC team or a multidisciplinary antimicrobial stewardship team. Local protocols for antimicrobial therapy of surgical infections and protocols for surgical antibiotic prophylaxis were present in 76.6% and 90.8% of hospitals, respectively. In 23.4% and 24.0% of hospitals no surveillance systems for surgical site infections and no monitoring systems of used antimicrobials were implemented. Patient and family involvement in IPC management was considered to be slightly or not important in their hospital by the majority of respondents (65.1%). Awareness of the global burden of AMR among HCWs was considered very important or important by 54.6% of participants. The COVID-19 pandemic was considered by 80.3% of respondents as a very important or important factor in raising HCWs awareness of the IPC programs in their hospital. Based on the survey results, the authors developed 15 statements for several questions regarding the prevention and management of infections in surgery. The statements may be the starting point for designing future evidence-based recommendations. Conclusion Adequacy of prevention and management of infections in acute care facilities depends on HCWs behaviours and on the organizational characteristics of acute health care facilities to support best practices and promote behavioural change. Patient involvement in the implementation of IPC is still little considered. A debate on how operationalising a fundamental change to IPC, from being solely the HCWs responsibility to one that involves a collaborative relationship between HCWs and patients, should be opened.

We study the flavor structure of the lepton and baryon number-conserving dimension-6 operators in the Standard Model effective field theory (SMEFT). Building on the work of [1], we define several well-motivated flavor symmetries and symmetry-breaking patterns that serve as competing hypotheses about the ultraviolet (UV) dynamics beyond the SM, not far above the TeV scale. In particular, we consider four different structures in the quark sector and seven in the charged lepton sector. The set of flavor-breaking spurions is (almost) always taken to be the minimal one needed to reproduce the observed charged fermion masses and mixings. For each case, we explicitly construct and count the operators to the first few orders in the spurion expansion, providing ready-for-use setups for phenomenological studies and global fits. We provide a Mathematica package SMEFTflavor (https://github.com/aethomsen/SMEFTflavor) to facilitate similar analyses for flavor symmetries not covered in this work.

Most modern missiles implement some variant of proportional navigation (PN) guidance law. In order to implement this form of navigation, the missile has to measure line of sight (LOS) rate. Devices capable to measure LOS rate are referred to as the seekers. This article aims to present analysis of a missile seeker mathematical models with purpose to obtain LOS rate estimation used for implementation of PN in three dimensions. This paper includes MATLAB simulations of developed seeker with 6-DOF nonlinear missile mathematical model and autopilot presented in earlier works by the authors.

With the decreasing reserves of conventional sources and the high emission of harmful gases caused by them, the inclusion of renewable energy sources in power system is increasing. However, to best utilize them, different site location criteria for PV generator installment need to be considered in the decision-making process. This paper presents Fuzzy Analytical Hierarchical Process (AHP) method used in energy planning to find the best Photovoltaic (PV) system site location for the established criteria and factors. Eight criteria were identified and evaluated. These include the solar energy potential, distance to the transmission line, PV surface slope, sunshine duration, the total amount of energy/PV, the temperature ratio, site survey, and performing shading analysis. PVGIS software tool is used to collect necessary data. Evaluation criteria are prioritized by applying fuzzy AHP, fuzzifying the inputs of the decision matrix using triangular fuzzy numbers. The obtained results and the methodology show potential in finding the best location where the PV system can be best utilized.
