Hachas kañaris: ¿objetos funcionales y/o simbólicos?
Authors: NARVÁEZ GEOVANNY 
Published: October 2022

Este artículo propone un análisis e interpretación sobre las hachas kañaris. Las hachas kañaris son objetos de metal precolombinos encontrados en la región austral del Ecuador, en el área de Ingapirca, las cuales pertenecen a la cultura kañar de la fase de Cashaloma. Estos objetos fueron posiblemente utilizados en diferentes manifestaciones culturales. De esta manera, se busca establecer una relación con el tumi o cuchillo ceremonial, objeto presente en algunas culturas precolombinas de la parte andina –Chimú, Moche, Lambayeque, Kañari e Inka–; y también con el topónimo tumipampa, antigua denominación de la actual ciudad de Cuenca (Ecuador). En específico se analizan seis hachas kañaris con el fin de plantear algunas hipótesis sobre las mismas, sus usos y significados –utilitarios, ceremoniales, medicinales, toponímicos, simbólicos– para aplicarlos posteriormente en un proyecto artístico audiovisual (tableaux vivants) y de esta manera incitar a la reflexión y debate desde la antropología y el arte.

Objectives: Main purpose of this study was evaluating inactive severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) vaccine subsequent anti-S1 IgG feedback and the aspects involved in such reactions for professionals in healthcare (HCP) as the dominant risk group.Methods: Thirty-six HCPs with previous COVID-19 infection and 164 with no priors, 200 in total, who was working in the Ankara Public Health Molecular Diagnosis Laboratory were included. Main tool of identifying humoral immune response quantifably in serum samples which were obtained 28 days after administering each of two doses of vaccine was Roche Elecsys SARS-CoV-2 kit. Results: Average antibody levels of 164 negative HCPs were 15.82 ± 8.59 IU/mL and 26.042 ± 10.73 IU/mL while 36 positive HCPs demonstrated antibody responses as 66.083 ± 33.927 IU/mL and 90 ± 27.012 IU/mL 28 days after each of two doses of vaccine for both individual groups respectively. A statistically meaningful difference was found in antibody levels after two vaccine doses in both groups (p &lt; 0.0001). The authors observed statistically higher average antibody levels after initial vaccine dosage in HCPs with infection than the antibody levels of naive individuals after second dose (p &lt; 0.0001). Age, gender and vaccination feedback did not have a statistically meaningful disparity (p &gt; 0.05). Conclusions: It was concluded that the average antibody level achieved after inital dose n HCPs with COVID-19 infection was surpassing the average antibody level obtained after the second dose in naive HCPs. The authors recommend further clinical researches on antibody levels and the extent of protection to prohibit COVID-19

Polonizacja nazewnictwa ulic, placów i mostów we Wrocławiu. Etap I, rok 1945. Analiza źródłowa
Authors: Kruszewski Tomasz 
Published: October 2022

Over the centuries, Wrocław (Breslau) had become a German city, alien to the Poles. In 1945, the Polonization of names was one of the most important undertakings. The changes were applied slowly (perhaps more names could have been translated), but demons of war dictated that Germanness should be erased. The research describes preserved legal acts from 1945, concerning the process of changing the names of German streets, squares and bridges in Wrocław. The study focuses on the figure of the lawyer Andrzej Jochelson. I have never asked Jochelson (the initiator of streets’ naming alteration) why, as a pioneer, he decided to focus on the Polonization of local naming. Jochelson was involved in this process until his death as a long-term head of the Committee of Street Naming of the Society of Wrocław Enthusiasts.
In 1945, 552 names were changed, of which less than half (248) were continuations, in which category I include four types: translations, re-establishing of old names, introducing new names connected with the location of the street, and changing names of commanders from German to Polish ones.

Published: October 2022

SummaryThe application of horizontal well drilling technology and volume fracturing technique makes the economic development of shale oil reservoirs feasible. The unknown fracture networks lead to severe nonlinearity and high uncertainty during fracture characterization. Moreover, the reservoir parameters usually exhibit a highly non-Gaussianity. Therefore, the key challenges for history matching in fractured shale oil reservoirs are effectively representing the fracture network and coping with the non-Gaussian distribution of reservoir-model parameters. In this work, a new characterization method for complex fracture networks is established, in which the distribution of connected fractures of the reservoir domain is represented by some statistical parameters such as fracture dip angle, fracture azimuth, and fracture half-length and some deterministic parameters such as the coordinates of fracture center points. In the uncertainty quantification and history-matching process, an integrated approach that combines the particle filter and an improved kernel density estimation (KDE) based on its Shannon entropy (SE) for estimating fracture distributions and physical parameters is presented. An adaptive mechanism based on Kullback-Leibler divergence (KLD) is introduced in the proposed history matching workflow, which automatically adjusts the number of particles to reduce the computational burden. Two examples of 3D shale oil production were constructed to validate the efficiency and accuracy of the proposed method. Results showed that the method was capable of capturing the main features of the fracture distributions in the reference cases. The proposed method has the potential to be applied in more complex cases such as multiple wells and multiphase flow.
Effect of blood pregnancy test time on IVF clinical outcomes in urine β-HCG-positive patients: A retrospective cohort study
Authors: KE XUE , Wang Fang , Lin Yong-hong 
Published: October 2022

Abstract
Background
To evaluate the optimal time of blood pregnancy test for urine beta-human chorionic gonadotropin (β-HCG)-positive patients following embryo transfer.
Methods
A total of 1,106 women who underwent embryo transfer between January 2019 and December 2019 were divided into three groups based on the time of positive pregnancy test at the hospital: the ≤ 9 days group (n = 355), the 10–12 days group (n = 598), and the ≥ 13 days group (n = 153). Clinical pregnancy ratio, ectopic pregnancy rate, multiple pregnancy rate, early miscarriage rate, late pregnancy loss rate, live birth ratio, preterm birth rate, very preterm birth rate, gestational week of delivery, and congenital malformation rate of the three groups were compared.
Results
The time preference for pregnancy test was 10 days among patients with D3 embryo transfer and 11 days among those with blastocyst transfer. Patients in the ≥ 13 days group were older and had a higher proportion of previous childbirth(s). Patients in the ≤ 9 days group had a higher live birth ratio and a lower risk of early miscarriage than the other two groups; similar results were seen in a sensitivity analysis that excluded women aged over 35 years and those with previous childbirth(s). Nevertheless, no differences were observed in the clinical pregnancy ratio, ectopic pregnancy rate, late pregnancy loss rate, very preterm birth rate, gestational week of delivery, or congenital malformation rate for all ranges of pregnancy test time. The pregnancy test time to predict the early miscarriage and live birth based on receiver operating characteristic (ROC) curve was day 9 after embryo transfer. After excluding women aged over 35 years or those with previous childbirth(s), the optimal time to conduct pregnancy test based on ROC curve was day 9 or 10 after embryo transfer in predicting early miscarriage, the pregnancy test time to predict live birth should be conducted on day 9 after embryo transfer.
Conclusion
Patients with positive results for urine β-HCG after embryo transfer should receive blood pregnancy test on day 9–10 after embryo transfer, which probably facilitated the optimization of live birth.
SVAD: Stacked Variational Autoencoder Deep Neural Network -Based Dimensionality Reduction and classification of Small Sample Size and High Dimensional Data
Authors: Srivast Neha , tayal Devendra 
Published: October 2022

Abstract
The classification problem is a major concern in the field of computational biology, especially when there are many fewer samples than features. This is referred regarded as a "curse of dimensionality" problem caused by high-dimensional sample size problems. Many strategies for dimensionality reduction have been presented, however, they all have drawbacks when it comes to high-dimensional and small sample size (HDSSS) databases, such as large variance gradients and over-fitting issues. To address these issues, we suggested a variational autoencoder based deep neural network architecture that is dynamic and based on a mathematical foundation for unsupervised learning. The objective of this research is to propose a low-error classification algorithm for limited sample numbers and high-dimensional datasets. The study's innovation is that it guarantees the permissible dimension size regardless of reduction, in contrast to several previous approaches that typically reduce the dimension too heavily.The experimental findings reveal that the suggested method outperforms existing traditional methods such as RNN, CNN, and deep network architecture.

Authors: Zhao Dewang , Jiang Chao , Ren Daxin , Zhao Kunmin 
Published: October 2022

Abstract
Ultrasonic welding is known as "green welding manufacturing technology" because of its fast, energy-saving, clean and pollution-free technical characteristics. Therefore, ultrasonic welding technology has a wide application prospect in aerospace, automobile and other fields. In this study, ultrasonic welding between AZ31B magnesium and pure copper are carried out. The fracture, microstructure and tensile properties of the joint are studied, and its connection mechanism is analyzed. The finite element analysis model of magnesium-copper ultrasonic welding process is established. The analyses of test results show that the fracture mode of magnesium-copper ultrasonic welded joint is interface-type fracture. The joint strength reaches the maximum value of 3798 N. The ultrasonic connection between magnesium alloy and copper is mainly realized by the interface diffusion layer formed in the welding process. The main component of the interface diffusion layer is mg2cu. The growth trend of interface diffusion layer is revealed. The analyses of FEM results show that the heat is generated in the central area of the solder joint, and then transferred around. The maximum temperature at the interface can reach 550 ℃. The distribution law of temperature field and plastic deformation field of joint are revealed.
Design and simulation of a semiconductor detector-based Compton imaging system with efficiency analysis
Authors: niknami mostafa , Hosseini Seyed Abolfazl , Loushab Mahdy Ebrahimi 
Published: October 2022

Abstract
In recent years, Compton cameras that use electronic collimators have become common. One or more scatterer detectors and an absorber detector make up the Compton camera, which is sensitive to the energy and location of scattered gamma rays. It predicts the distribution of gamma-ray sources by reflecting all valid events in the image space using conical surfaces. Compton cameras are designed for specific applications and image reconstruction using various methods.
Based on studies on the efficiency of the Compton camera, the current work provides a novel detector design that includes scatterer and absorber detectors. This design includes eight scatterer detectors spaced 1 mm apart and an absorber detector 30 mm from the last scatterer detector. The distance between the source and the first scatterer detector was 5 mm. The scatterer and absorber detector plates were 70*70*2.125mm3 and 70*70*10mm3, respectively. The Compton imaging system is simulated using the GEANT4 toolkit.
In addition, this study uses an analytical method to reconstruct Compton camera images. The method used for analytical reconstruction in the Compton imaging system differs slightly from simple restoration methods used in other imaging systems. In the analytical method, the equation related to the data reflected by the image must be solved to reconstruct the image directly. This method, the C++ code was developed to reconstruct Compton camera images.
According to the results, using the analytical method to identify the best circumstances and the parameters impacting efficiency, the value of FWHM achieved was 3.7 mm with an angular uncertainty of about 2.7 at an energy of 0.662 MeV. Furthermore, the FWHM value decreased by 0.7 mm, compared to another (experimental) design that employed the analytical image reconstruction approach.
Hemiplegic Migraine as Cause For Motor Vehicle Collision: A Case Report
Authors: Esguerra Jody , Sherman Andrew , Bukovec Florian 
Published: October 2022

Abstract
Introduction: Hemiplegic migraine (HM) is a rare, heterogenous form of migraine characterized by unilateral weakness. This motor aura can present with reversible visual, sensory, and language deficits. HM can be difficult to diagnose due to overlapping presentation with other complex conditions such as multiple sclerosis, seizure disorders, and transient ischemic attack (TIA).
Case Presentation: We describe a case of a 40 year old with asymptomatic COVID-19 infection who presented after a motor vehicle collision caused by HM consistent with left sided weakness and loss of consciousness.
Conclusions: To date, this is the first description of a patient with known complex migraines to have a motor vehicle collision as a result of HM. The risk of HM-associated neurologic symptoms while driving poses a significant public safety concern. We suggest driving restrictions be considered in patients with HM when migraine aura is present. This case presents support to examine active infection with SARS-CoV-2 as a trigger for HM.

Abstract
Background: Ventilator-associated pneumonia (VAP) is a significant and common health concern, and epidemiological landscape of VAP is poorly understood in neurosurgery. The current study aimed to explore the epidemiology of VAP in neurosurgery to devise better-targeted surveillance, treatment and control efforts.
Methods:A ten-year retrospective study was performed in a large Chinese tertiary hospital. We collected surveillance data on neurosurgical patients with VAP and used descriptive analysis to map the demographic and clinical characteristics of VAP as well as the distribution and antimicrobial resistance profile of leading pathogens. Risk factors associated with VAP were explored using boosted regression tree (BRT) models.
Results:During 2011-2020, 310 VAP patients were identified. The ten-year incidence of VAP was 16.21 per 1000 ventilation days with an all-cause mortality rate of 6.1%. The proportions of gram-negative bacteria, fungi, and gram-positive bacteria in 357 isolates from 310 VAP patients were 86.0%, 7.6% and 6.4%, and most were multidrug-resistant organisms. Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa were the most common pathogens causing VAP, and high detection rates of CRAB, CRPA and CRKP with an upward trend were observed. The BRT modes revealed that there were significant associations of VAP presence with the days of ventilator use (relative contribution: 47.84 ± 7.25), GCS score (relative contribution: 24.72± 5.67), and tracheotomy (relative contribution: 21.50 ± 2.69), respectively.
Conclusions: Our findings better understand epidemiological characteristics and risk factors for VAP in neurosurgery.

Published: October 2022

Abstract

In order to study the deformation mechanism of sand around the spudcan, the model test for spudcan-sand interaction was carried out by employing transparent media, which is also called "transparent soil". By means of the technology of Particle Image Velocimetry (PIV), the displacement vector field and contour map of sand around the spudcan were obtained. According to shallow strain path method (SSPM), the theoretical value of soil displacement around the spudcan was calculated. Compared with the experimental results, the correlation between the variation law of horizontal displacement of each group and the theoretical value reached 60%~80% in a certain range, which further verifies the rationality of the experimental method and theoretical analysis.
