Abstract
Optical generation of kilo-tesla scale magnetic fields enables prospective technologies and fundamental studies with unprecedentedly high magnetic field energy density. A question is the optimal configuration of proposed setups, where plenty of physical phenomena accompany the generation and complicate both theoretical studies and experimental realizations. Short laser drivers seem more suitable in many applications, though the process is tangled by an intrinsic transient nature. In this work, an artificial neural network is engaged for unravelling main features of the magnetic field excited with a picosecond laser pulse. The trained neural network acquires an ability to read the magnetic field values from experimental data, extremely facilitating interpretation of the experimental results. The conclusion is that the short sub-picosecond laser pulse may generate a quasi-stationary magnetic field structure living on a hundred picosecond time scale, when the induced current forms a closed circuit.

Published: December 2021

Abstract
This research aims at understanding the impact of welding process parameters and beam oscillation on the weld thermal cycle during laser welding. A three-dimensional heat transfer model is developed to simulate the welding process, based on the finite element (FE) method. The calculated thermal cycle and weld morphology are in good agreement with experimental results from literature. By utilizing the developed heat transfer model, the effect of welding process parameters such as heat source power, welding speed, radius of oscillation, and frequency of oscillation on the intermediate performance indicators (IPIs) such as peak temperature, heat-affected zone volume (HAZ), and cooling rate is quantified. Parametric contour maps for peak temperature, HAZ volume, and cooling rate are developed for the estimation of the process capability space. An integrated approach for rapid process assessment, process capability space refinement, based on IPIs is proposed. The process capability space will guide the identification of the initial welding process parameters window and help in reducing the number of experiments required by refining the feasible region of process parameters based on the interactions with the IPIs. Here, the peak temperature indicates the mode of welding performed while the HAZ volume and cooling rate are weld quality indicators. The regression relationship between the welding process parameters and the IPIs is established for quick estimation of IPIs to replace time-consuming numerical simulations. The proposed approach provides a unique ability to simulate the laser welding process and provides a robust range of process parameters.

Abstract
Striatin and SG2NA are scaffold proteins that from signalling complexes called STRIPAK. It has been associated with cancer and other diseases. Our earlier studies have shown that SG2NA forms a complex with the cancer associate protein DJ-1 and signalling kinase Akt, promoting cancer cell survival. In the present study, we used bioinformatics analyses to confirm the existence of two isoforms of human SG2NA i.e., 78 and 87 kDas. In addition, several smaller isoforms like 35 kDa were also seen in western blot analyses of human cell lysates. The expression of these isoforms varies between different human cancer cell lines. Also, the protein level does not corroborate with its transcript level, suggesting a complex regulation of its expression. In breast tumour tissues, the expression of the 35 and 78 kDa isoforms was higher as compared to the adjacent normal tissues, while the 87 kDa isoform was detected in the breast tumour tissues only. With the progression of stages of breast cancer, the expression of 78 kDa isoform decreased, while 87 kDa became undetectable. In coimmunoprecipitation assay, the profile of SG2NA interactome in breast tumor vis-à-vis adjacent normal breast tissues shows hundreds of common proteins, while some proteins specifically interacted in breast tumour tissue only. We conclude that SG2NA is involve in diverse cellular pathways and have roles in cellular reprogramming during tumorigenesis.

Abstract
The application of iron oxide as anode of lithium-ion batteries is hindered by its poor cycle stability, low rate performance and large voltage hysteresis. To address these problems, multi-channel surface modified amorphous Fe2O3 nanospheres were synthesized by using a facile hydrothermal method, which exhibited outstanding electrochemical performances. According to crystalline state and microstructure, it was found that surface structure of the amorphous Fe2O3 nanospheres can be controlled by adjusting the reaction time, due to the synergistic effect of ripening and hydrogen ion etching. Owing to the isotropic nature and the absence of grain boundaries, the amorphous Fe2O3 nanospheres could withstand high strains during the intercalation of lithium ions. Meanwhile, the multi-channel surface structure can not only increase the contact area between Fe2O3 nanospheres and electrolyte, but also reserve space for volume expansion after lithium storage, thereby effectively alleviating the volume change during the intercalation-deintercalation of lithium ions. As confirmed by the Galvanostatic intermittent titration analysis results, the amorphous Fe2O3 electrode had higher Li+ diffusion coefficient than the crystalline counterpart. As a result, the multi-channel surface modified amorphous Fe2O3 electrode exhibited higher specific capacity, more stable cycle performance and narrower voltage hysteresis. It is believed that amorphous metal oxides have great potential as high-performance anode of next-generation lithium-ion batteries.

Abstract
Iran has a great advantage in the development of the steel industry due to its access to mineral resources and energy, extensive consumer market, and low-cost labor. In this article, the Iranian steel value chain in 2014-2016 is studied using the value chain analysis and material flow analysis. Accordingly, based on the statistics related to the input and output of each echelon in the chain, the material flow is analyzed throughout the value chain. Then the total added value from the chain, the share of different stages, and the various costs in each echelon are calculated. According to the research findings, weakness in the development of transportation infrastructure and poor geographical distribution of value chain units has led to the deviation of production from nominal capacity and frequent imports/exports throughout the chain. On the other hand, the upstream industries have a permanent advantage that deeply roots in easy access to the minerals and lower costs in transportation and energy. Finally, the pricing of intermediate products based on the ratio of steel ingot prices is criticized, while wage conversion and commodity purification contracts are proposed as possible solutions for the reduction of overhead costs.

Abstract
BackgroundThe lifestyle of children has a significant impact on the future health of the whole society. Therefore, health education, prevention and monitoring of health determinants is important at every stage of ontogenesis. This requires a thorough knowledge of the schoolchild's environment, perceived as a wide set of stressors, including not only genetic but also epigenetic factors. One of them is the issue of the correct and abnormal body posture at school and on the way there.MethodBody posture tests were carried out in a group of 65 students aged 7 years, using the projection moiré method in 4 positions: 1-habitual posture, 2-posture after 10-minute of asymmetric axial load, 3-a posture after one minute of the load removal, 4- a posture after two minutes of the load removal. Physical fitness was measured with the Sekita test. ResultsThe significance of differences between the 1st and 2nd measurements was analyzed to determine the impact of the backpack load and the correlation with physical fitness, and to study its influence on the value of the differences in posture features. ConclusionsCarrying school supplies on the back induces significant changes in the value of the features describing the body posture in the frontal plane. It should be assumed that the greater the weight of the container and, carrying time and intensity of physical effort is the greater the changes will be. Relatedly, it is not recommended to carry school supplies weighing more than 4 kg by first-grade students.Physical fitness has a various and sex-dependent influence on the value of changes in body posture features because of carrying school supplies. Among boys it significantly affects the asymmetry of the torso bend, shoulder height, the waist triangles height and width, whereas among girls it affects the asymmetry of the shoulders and the distance of the angles of the lower shoulder blades from the line of the spinous processes of the spine. Among boys the changes in the value of posture features are mostly influenced by endurance and speed, but strength, power and agility are of lower influence, whereas among girls only agility matters.

Abstract
PurposeThe role of surgical resection in the treatment of anaplastic glioma is poorly understood. The aim of the present retrospective study was to clarify the survival of patients with anaplastic gliomas.MethodsWe utilized the SEER database to assess the association between prognostic and demographic data, tumor characteristics, and treatment factors in adult patients with anaplastic glioma. Overall survival and cause-specific survival were analyzed using multivariable Cox regression and competing risk regression, respectively.ResultsA total of 3979 patients with anaplastic glioma who had undergone surgical intervention were included in the analysis. Patients who underwent gross total resection (GTR) had significantly better 5-year and 10-year overall survival (OS) (59.9% vs. 44.0%, 45.0% vs. 29.4%, p < 0.001) than those who did not. The 5-year and 10-year cumulative incidence rates of cancer-specific death in the GTR group were lower than those in the corresponding N-GTR group (36.6% vs.51.9%, 49.9% vs. 65.5%, p < 0.001). Multivariable analysis identified GTR as an independent significant predictor for prolonged OS (HR:0.72; 95% confidence interval [CI] 0.65-0.79, P<0.05) and cause-specific survival (CSS) (HR:0.72, 95% CI 0.65-0.80, P<0.05).Further subgroup analysis revealed a stable association between the extent of resection and OS (P values for interaction >0.05), except for tumor location and histologic type groups.ConclusionsWhile the survival of patients with anaplastic glioma remains poor, GTR is associated with increased OS and CSS compared to N-GTR.

Abstract
Background: Diseases of the oral cavity are heterogenous in etiology, pathogenesis, histogenesis and clinical outcome. Several epidemiologic studies exist in the literature with variable and conflicting results, based on small sized-samples and geographic factors. The aim of this study is to examine the frequency of oral diseases encountered in our experience from a tertiary hospital and to compare it with previous studies.Methods: The archives of pathology at Jordan University Hospital were retrospectively searched for specimens of oral cavity and related structures anatomic areas between 2013-2020. Fisher’s exact test was performed to examine the statistical difference between the pathologic diagnosis and clinical variables of age, gender and site of specimen. One-way ANOVA test was applied to analyzed the differences in the mean of age among different pathologic groups. P-value of less than 0.05 was considered significant.Results: A total of four-hundred forty-one cases were retrieved. There were 232 (52%) females and 210 (48%) males. The range of age was 3-87 years (mean 43), 46 (10%) of which were children younger than 16 years. Inflammatory and reactive diseases were the most common, constituting 147 (33%) of all specimens, followed by benign neoplasms: 139 (31%), cysts: 114 (26%) then malignant diseases: 42 (10%). Lichen planus was the most common inflammatory disease: 26/147 (18%) and prevailed in patients older than 40 years (P = 00039). Keratocyst predominated in children and adolescents more than in adults (P = 0.0015). Buccal mucosa represented the most frequent site for biopsy: 76 (17%), followed by tongue and maxillary bone: 70 (16%), each. Conclusion: Inflammatory and benign neoplasms are the most common lesions in oral diseases. Oral malignancy appears to show a low to intermediate frequency compared to previous reports. The study provides a general overview of the spectrum of oral pathology specimens and points to some novel epidemiologic findings that suggests further investigations.

Published: December 2021

Abstract
BackgroundBottle gourd (Lagenaria siceraria) is sometimes used in complementary medicine practice for the treatment of chronic ailments. It belongs to the Cucurbitaceae family. However, there have been reports of toxicity due to consumption of bottle gourd juice leading to severe abdominal upset and upper gastrointestinal bleeding. As emergency physicians we need to be aware of such complementary medicine induced haemorrhagic gastroenteritis as possible etiology of gastrointestinal haemorrhage. Case presentationWe present a case of a 41-year-old gentleman who presented to the emergency department (ED) with multiple episodes of vomiting, hematemesis and diarrhoea after consuming bottle gourd juice. The patient was resuscitated and stabilized with fluids, proton pump inhibitors and antiemetics. He was subsequently admitted to General Medicine ward for further management. He continued to receive symptomatic treatment in the ward and underwent esophagogastroduodenoscopy (OGD) during his hospitalization stay. His symptoms improved and he was discharged stable five days later. ConclusionEarly recognition of this rare presentation of bottle gourd toxicity is important in our local context especially where traditional medicine is widely prevalent nowadays. Treatment is supportive. Public awareness of dangerous effects from the consumption of bitter bottle gourd juice and complementary medicine without proper consultation with practitioner plays a crucial role to prevent further cases. Physicians need to advise patients on the use of traditional medicine and their potential side effects.

Abstract
Thin, lightweight, and flexible textile pressure sensors with the ability to detect the full range of faint pressure (<100 Pa), low pressure (in the range of KPa) and high pressure (in the range of MPa) are in significant demand to meet the requirements for applications in daily activities and more meaningfully in some harsh environments, such as high temperature and high pressure. However, it is still a significant challenge to fulfill these requirements simultaneously in a single pressure sensor. Herein, a high-performance pressure sensor enabled by polyimide fiber fabric with functionalized carbon-nanotube (PI/FCNT) is obtained via a facile electrophoretic deposition (EPD) approach. High-density FCNT is evenly wrapped and chemically bonded to the fiber surface during the EPD process, forming a conductive hierarchical fiber/FCNT matrix. Benefiting from the large compressible region of PI fiber fabric, abundant yet firm contacting points, point-to-point contacting mode, and high elastic modulus of both PI and CNT, the proposed PI/FCNT pressure sensor can be customized and modulated to achieve both a wide linear ranges, ultra-broad sensing range, long-term stability and high-temperature resistance. Thanks to these merits, the proposed PI/FCNT(EPD) pressure sensor could monitor the human physiological information, detect tiny and extremely high pressure, can be integrated into an intelligent mechanical hand to detect the contact force under high-temperature (>300 ºC), endowing it with high applicability in the fields of real-time health monitoring, intelligent robots, and harsh environments.

Published: December 2021

Abstract
The current study presents an efficient method for deriving precise operation rules from all subsystems of a distributed conjunctive use system (CUS), including aquifer, river, and reservoir. Distributed aquifer simulation has been performed using the URM method. Given that the historical flow time series can only represent one of the possible situations in the future and its use to determine the performance of the CUS is certainly not very reliable, in this study, river flow uncertainties are implicitly considered. To develop the operation rules, the time series of river flow were generated using autoregressive model. Then, the operation optimization model of the system was implemented with the objective function of minimizing water shortage for different river flow time series. 70% of the data was used for model training and 30% for model validation. Finally, using the decision tree algorithm (M5Rules), the conditional operation rules were extracted and compared with the single linear regression operation rules. Using five efficiency criteria CC, MAE, RMSE, RAE, and RRSE, the comparison of conditional and single linear regression operating rules has been done. The results showed that the the conditional operation rules reduces relative absolute error by a minimum of 39% and a maximum of 71%. If the system is operated according to the conditional rules, in the worst case, the amount of water shortage imposed will be 16.61 MCM over ten years.
