Published: July 2022

Introduction: Analysis of the outcome of 268 ICU patients in a single-center, as well the impact of viral infection on patients with preexisting medical conditions and how these factors affected survival and hospital stay.
Methodology: Patients admitted to the ICU from March-August, 2020 were retrospectively analyzed under the same protocol at Hospital Alemão Oswaldo Cruz, São Paulo, Brazil. Several factors were considered and the results were presented using 95% confidence intervals. For statistical significance, p <0.05 was adopted.
Results: Patient median age was 72 years, 64,2 years for discharged patients and 79.9 years for those deceased (p<0.001). The most common comorbidities were: systemic arterial hypertension, diabetes, thyroid disease, cardiovascular and kidney disease. Predictors of survival through univariate analysis: myalgia (p=0.001), cerebrovascular disease (p=0.002), COPD (p=0.003), dementia (p=0.000), mechanical ventilation (p=0.000), dialysis (0.000), vasopressor use (0.000), SAPS3 (0.000), lymphopenia (p=0.004), elevated D-dimer (P=0.011), time in ICU before tracheostomy (p=0.002), and performing a tracheostomy (p=0.000). The independent predictors of mortality were: advanced age (p=0.003) and tracheostomy performed in ICU (p=0.002).
Discussion: COVID-19 affects usually older adults, where there already is a higher fatality rate. Acute respiratory distress syndrome is the primary cause of death and <5% of patients were reported as experiencing co-infection at admission.
Conclusion: age, vasopressor use in patients with tracheostomy, and systemic coronary disease, heart failure, neoplasia, and COPD, were found to be significantly associated with COVID-19 severity.

Authors: Castillo-Argañarás Luis-Fernando 
Published: July 2022

El objetivo de este artículo es analizar la cooperación internacional entre Argentina y China sobre la utilización de la estación espacial construida en la Patagonia, en el marco de una asociación estratégica integral. Se realiza un análisis documental, mediante la recolección de datos y una estrategia cualitativa basada en la inducción y deducción. Se concluye que los acuerdos que establecen la estación espacial en el marco de la asociación estratégica son “tratados desiguales”, de la misma naturaleza que los firmados por China en el siglo XIX y principios del XX.

Abstract
The objective of this article is to analyze the international cooperation between Argentina and China in relation to the use of the space station built in Patagonia, within the framework of a comprehensive strategic partnership. Documentary analysis is carried out by collecting data and implementing a qualitative strategy based on induction and deduction. It is concluded that the agreements that establish the Space Station within the framework of the strategic association are “unequal treaties” of the same nature as those signed by China in the 19th and early 20th centuries.

Published: July 2022

Introduction. Combustible cigarette use is associated with an increased risk of several cardiovascular diseases; however, less is known about associations between these cardiovascular conditions and electronic cigarette use.
Methods. This study investigated relationships between electronic and/or combustible cigarette use and diagnoses of cardiovascular diseases using the National Health Interview Survey from 2014, 2016, 2017, and 2018.
Results. Compared to non-users, dual users of electronic and combustible cigarettes had increased likelihood of having prior diagnoses of hypertension (OR 1.660, 95% CI=1.519-1.814), stroke (OR 2.396, 95% CI=2.011-2.855), diabetes mellitus (OR 1.219, 95% CI=1.108-1.341), coronary artery disease (OR 2.211, 95% CI=1.837-2.660), and myocardial infarction (OR 3.839, 95% CI=3.232-4.560). Exclusive use of electronic cigarettes was associated with an increased likelihood of having hypertension compared to non-users (OR 1.244, 95% CI=1.048-1.477).
Conclusions. There was no difference in diagnoses of stroke, diabetes mellitus, coronary artery disease, nor myocardial infarction among exclusive electronic cigarette users compared to non-users; however, these associations could change as young electronic cigarette users with hypertension age, indicating the need for continued research.
Determination of Borehole Seismic Sensor Orientation Using Microseisms
Authors: Park Seongjun , Hong Tae-Kyung , Lee Junhyung 
Published: July 2022

ABSTRACT
We introduce a novel method to determine the azimuthal orientation of borehole seismometer using microseisms that are ubiquitously present in seismic records. The microseisms are dominantly composed of Rayleigh waves that construct plane wavefronts over local stations. We determine the borehole seismometer orientation by comparing the polarization directions of Rayleigh waves in microseisms between borehole and surface stations. The Rayleigh wave polarization directions are determined using the nature of Rayleigh wave ground motions that present a 90° phase difference between the radial and vertical components. The azimuthal differences in apparent Rayleigh wave polarization directions between borehole seismometer and local surface seismometer provide information on the misorientation angle of borehole seismometer. Both the primary and secondary microseisms can be used. The method is applied to determine the misorientation angles of two deep borehole seismometers in the Yonsei Earth Observatory in Seoul, South Korea. The misorientation angles of borehole seismometers are determined stably using 18-hour-long ambient noise records, suggesting instant determination of borehole seismometer orientation based on short-time ambient noise records. Regional-event seismic waveforms at borehole seismometers match well with those at collocated surface station, supporting the correct determination of borehole seismometer orientation. The proposed method does not require information on seismic source locations and ray paths unlike conventional methods, allowing prompt determination of borehole seismometer orientation with high precision.
A Machine-Learning Approach for the Reconstruction of Ground-Shaking Fields in Real Time
Authors: Fornasari Simone Francesco , Pazzi Veronica , Costa Giovanni 
Published: July 2022

ABSTRACT
Real-time seismic monitoring is of primary importance for rapid and targeted emergency operations after potentially destructive earthquakes. A key aspect in determining the impact of an earthquake is the reconstruction of the ground-shaking field, usually expressed as the ground-motion parameter. Traditional algorithms compute the ground-shaking field from the punctual data at the stations relying on ground-motion prediction equations computed on estimates of the earthquake location and magnitude when the instrumental data are missing. The results of such algorithms are then subordinate to the evaluation of location and magnitude, which can take several minutes. To fill the temporal gap between the arrival of the data and the estimate of these parameters, a new data-driven algorithm that exploits the information from the station data only is introduced. This algorithm, consisting of an ensemble of convolutional neural networks (CNNs) trained on a database of ground-shaking maps produced with traditional algorithms, can provide estimates of the ground-shaking maps and their associated uncertainties in real time. Because CNNs cannot handle sparse data, a Voronoi tessellation of a selected peak ground parameter recorded at the stations is computed and used as the input to the CNNs; site effects and network geometry are accounted for using a (normalized) VS30 map and a station location map, respectively. The developed method is robust to noise, can handle network geometry changes over time without the need for retraining, and can resolve multiple simultaneous events. Although having a lower resolution, the results obtained are statistically compatible with the ones from traditional methods. A fully operational version of the algorithm is running on the servers at the Department of Mathematics and Geosciences of the University of Trieste, showing real-time capabilities in handling stations from multiple Italian strong-motion networks and outputting results with a resolution of 0.05° × 0.05°.
Detecting and Locating Aftershocks for the 2020 Mw 6.5 Stanley, Idaho, Earthquake Using Convolutional Neural Networks

Published: July 2022

Abstract
Our study is to build an aftershock catalog with a low magnitude of completeness for the 2020 Mw 6.5 Stanley, Idaho, earthquake. This is challenging because of the low signal-to-noise ratios for recorded seismograms. Therefore, we apply convolutional neural networks (CNNs) and use 2D time–frequency feature maps as inputs for aftershock detection. Another trained CNN is used to automatically pick P-wave arrival times, which are then used in both nonlinear and double-difference earthquake location algorithms. Our new one-month-long catalog has 4644 events and a completeness magnitude (Mc) 1.9, which has over seven times more events and 0.9 lower Mc than the current U.S. Geological Survey National Earthquake Information Center catalog. The distribution and expansion of these aftershocks improve the resolution of two north-northwest-trending faults with different dip angles, providing further support for a central stepover region that changed the earthquake rupture trajectory and induced sustained seismicity.

Published: July 2022

ABSTRACT
The purpose of this study is to identify the factors that play a role in building Human Resources for Higher Education Lecturers and the process of their formation. This study uses a quantitative approach, collecting data using a questionnaire to 166 lecturers from higher education in Karawang Regency, West Java. Data analysis used factor analysis and dendogram analysis. The results of factor analysis showed that all indicators were analyzed from the basic components, moderators, supporters and outputs of Human Resources for Higher Education Lecturers. The results of the dendogram analysis inform that the process of forming the Human Capital for Higher Education Lecturers begins with educational activities and faculty skills. This research is still in the study of the identification of intellectual capital which is explained to individual university lecturers with a small sample area, so it is still necessary to develop the intellectual capital relationship of lecturers with other variables that reflect the university's business processes. The results of this study greatly contribute to explaining the potential of human capital as an intangible asset of higher education and the process of its formation, so that universities can understand how to develop lecturers' human capital so that its potential can be used for the development of higher education as a whole.

Authors: Morito Takaki , Kida Yoshikazu , Takatsuji Kenta , Katsuyama Yusei , Takahashi Kenji 
Published: July 2022

Case:
We describe a case of Hegemann's disease in a 10-year-old boy practicing karate. The disease was discovered by chance when evaluating a traumatic olecranon fracture. Radiography showed not only olecranon fracture but also a shortening of the epiphysis of the humeral trochlea and a segmental lesion with sclerosis. The trochlea lesion was considered asymptomatic Hegemann's disease. After the olecranon healed conservatively, the patient resumed karate activities and underwent follow-up radiography. The trochlea lesion gradually normalized after 2 years without symptoms.

Conclusions:
Regardless of the initial alarming radiographic findings, the lesion gradually healed, and the patient was able to return to sports activities.

Authors: Brown Marcel G. , LaRoque Michael C. , Cole Peter A. 
Published: July 2022

Case:
The case of an active 16-year-old adolescent girl who presented with rib malunion and 1 year of unremitting intercostal nerve pain after sustaining multiple rib fractures is presented. She underwent successful bony and soft-tissue decompression of her eighth and ninth intercostal nerves to relieve neurogenic symptoms.

Conclusion:
When conservative treatment fails, chronic intercostal nerve pain due to chest wall trauma may be effectively managed with surgical bony decompression of the offending intercostal bundle(s). Anatomic knowledge of the intercostal nerve and a critical history and physical examination were critical for accurate diagnosis and surgical decompression of the patient's intercostal nerve.

Published: July 2022

Case:
We present a case of dysplasia epiphysealis hemimelica (DEH) involving the posteromedial distal femur in a 4-year-old girl. The patient underwent lesion resection with internal fixation of the articular cartilage followed by autologous chondrocyte implantation (ACI) to restore the articular surface and epiphysis. At the 7-year follow-up, the patient had no pain or difficulty with participation in sports. Advanced imaging showed a stable articular surface with evidence of durable cartilage integration.

Conclusion:
DEH is a rare disease often treated by resection. In cases where the articular surface of the knee is involved, we have demonstrated that augmentation with ACI can be an effective treatment option.
Mechanical Behavior and Failure Process of Hard Rock with Rock Bridge under Uniaxial Compression Test
Authors: Zhang Yan , Chen Guoqing , Gao Yaohui , Xu Yitian , Liu Ding 
Published: July 2022

Abstract
The mechanical properties of rock mass are mostly controlled by the structural plane. Rock bridge has an important effect on the failure and stability of rock mass with structural plane. In this paper, the uniaxial compression test of hard rock containing rock bridge is carried out, accompanied by acoustic emission (AE) and high-speed video monitoring. Within the scope of this study, the results show that the uniaxial compressive strength (UCS) of sample with rock bridge increases with the rock bridge length. Under the same stress condition before peak, the strain of the sample decreases with the increase of the rock bridge length (RBL). Under the influence of stress concentration, the cracking of the sample starts from the prefabricated crack tip. The peak AE count of the sample decreases with the increase of RBL. The AE cumulative energy of the sample increases with the increase of RBL. The number of cracks in the sample before the peak is small, and the rapid increase of cracks is mainly concentrated in the main fracturing stage after the peak, while after reaching the residual stage, the increase rate of various types of microcracks in the sample is relatively slow. The numerical simulation results show that the number of all kinds of cracks in the sample before the peak is small, and the number of tensile cracks in the sample is very close to the total number of cracks under different RBLs. With the increase of RBL, the tensile/shear crack ratio decreases. The internal cracks of the sample are mainly concentrated at the peak stress and postpeak stage. The research results of this paper are of great significance to the engineering excavation and safe construction of jointed rock mass engineering.

Abstract
Introduction : The present study aimed to determine the impact of vitamin D supplementation on recovery delay among COVID-19 patients. Methods : We performed a randomized controlled clinical trial in the national center for COVID-19 confinement, from May to August 2020. Simple randomization was done in a 1:1 allocation ratio. We included patients aged more than 18 years who had confirmed RT PCR and who remained positive on the 14 th day. The intervention group received vitamin D supplementation (200,000 IU / 1 ml of Cholecalciferol), the control group received a placebo treatment (physiological saline (1 ml)). We measured the recovery delay and the E gene SARS-CoV-2 RT-PCR Cycle threshold (Ct) values. The Log rank test and Hazard ratios (HR) were calculated. Results : A total of 117 participants were enrolled. The mean age was 42.7 years (SD 14). Males represented 55.6%.The median duration of viral RNA conversion was 37 days ( 95% CI: 29-45.50) in intervention group and 28 days ( 95% CI: 23-39) in the placebo group (p=0.010). HR was 1.58 ( 95% CI: 1.09-2.29, p=0.015). Ct values revealed a stable trends over time in both groups. Conclusion : Vitamin D supplementation was not associated with a shortened recovery delay when given to patients for whom the RT-PCR remained positive on the 14th day. Trial registration: This study was approved by the Human Subjects Protection Tunisia center (TN2020-NAT-INS-40) on May 05, 2020 and by clinical trial.gov with approval number Clinical Trials.gov ID: NCT04883203.

Published: July 2022

Abstract
The full-field multiaxial strain measurement is highly desired for application of structural monitoring but still challenging, especially when the manufacturing for large-area sensing devices is quite difficult. In this work we propose an integrated strategy from layered circuit scheme to rapid manufacturing of strain rosette sensor array based on the direct-ink-writing (DIW) technology. Benefit from the innovative design with simplified circuit layout and the advantages of DIW for printing multilayer structures, here we achieve optimization design principle for strain rosette sensor array with scalable circuit layout, which enable a hierarchical printing strategy for multiaxial strain monitoring in large scale or multiple domains. The strategy is highly expected to adapt for the emerging requirement in various applications such as integrated soft electronics, nondestructive testing and small-batch medical devices.

Abstract
Bovine mastitis is an inflammation of mammary gland parenchyma in cows. It is caused by multiple pathogens including bacteria and fungi. Mycotic mastitis is a secondary disease following improper frequent use of antibiotics or an unhygienic environment. The treatment of rising cases of mycotic mastitis is still controversial because of the rapid resistance acquired by the traditional use of antifungal drugs. The present study aims to investigate the use of zinc oxide nanoparticles (ZnO-NPs), alternative therapy for traditional antifungal drugs, to combat fungal isolates from mastitic cows by examining the in vitro antifungal activity of ZnO-NPs. One hundred milk samples were aseptically collected from cows suffering from clinical mastitis in a governorate in Egypt. The fungal isolates were identified by their colony morphology and microscopical examination and subsequent underwent determining the MIC of traditional antifungal drugs and ZnO-NPs using the disc diffusion methods. Our results showed that 70% of milk samples were positive for mycotic mastitis with 30% yeasts, 15% molds, and 25% yeast and molds. Candida was the most common yeast species isolated. Rhodotorula, c. guilliermondii, c. parapsillosis, and c. albicans showed entire resistant (100%) to all traditional antifungal drugs whereas, the same isolates, except c. albicans, were susceptible to ZnO-NPs. Mold spp. were susceptible to ZnO-NPs and only Itraconazole, and Clotrimazole. ZnO-NPs are highly effective and promising inexpensive antimicrobial agent for the treatment of bovine mycotic mastitis.
