Authors: Zaidi Syeda Mahrukh Fatima , Shaukat Shuja , Shan Mishal , Ayesha Shabih 
Published: August 2023

Abstract
Background
Penetrating brain traumas entail the intrusion of external items into the cranial cavity without an exit point. While commonly accompanied by neurological impairments, exceptional instances exist where patients exhibit no deficiencies. Our study delves into the phenomenon of penetrating brain injuries without neurological deficits in the pediatric age group, offering valuable insights for clinical practice.
Cases Presentation:
We hereby report two noteworthy cases of pediatric patients who presented with accidental penetrating brain injuries, involving a pencil and a toy wheel, respectively. Subsequent imaging examinations revealed deep penetration within the brain parenchyma. Remarkably, neither of these cases exhibited any discernible neurological deficits or symptoms typically associated with traumatic brain injury.
Conclusion
Penetrating brain injuries pose significant risks and require immediate and meticulous management in trauma centers.
Censored Mean Level CFAR detectors for Statistical MIMO radars
Authors: Baadeche M. , Soltani F. 
Published: August 2023

Abstract
In this paper three censored mean (CM) level CFAR detectors are proposed; the Mean of CM (MCM), the CM Greatest Of (CMGO) and the CM Smallest Of (CMSO); and their performances are analyzed in homogeneous and non-homogeneous clutter for Multi-Input Multi-Output (MIMO) radars with widely separated antennas (Statistical). Closed-form expressions of the probability of false alarm (PFA) and probability of detection (PD) are derived for the three CFAR detectors in homogeneous environment. By means of closed-form in homogeneous clutter and Monte Carlo simulations in non-homogeneous clutter, the detection performance of the three CFAR detectors is investigated and compared.

Abstract
Background: Neuromuscular diseases (NMD) emerged as one of the main side effects of the COVID-19 vaccination. We pooled and summarized the evidence on the clinical features and outcomes of NMD associated with COVID-19 vaccination.
Methods: We comprehensively searched three databases, Medline, Embase, and Scopus, using the key terms covering “Neuromuscular disease” AND “COVID-19 vaccine”, and pooled the individual patient data extracted from the included studies.
Results: A total of 258 NMD cases following COVID-19 have been reported globally; of which 171 cases were Guillain barre syndrome (GBS), 40 Parsonage-Turner syndrome (PTS), 22 Myasthenia Gravis (MG), 19 facial nerve palsy (FNP), 5 single fiber neuropathy, and 1 Tolosa-Hunt syndrome. All (100%) SFN patients and 58% of FNP patients were female; in remained NMDs, patients predominantly were male, including MG (82%), GBS (63%), and PTS (62.5%).
The median time from vaccine to symptom was less than 2 weeks in all groups. Symptoms mainly appeared following the first dose of vector vaccine, but there was no certain pattern for mRNA-based.
Conclusion: COVID-19 vaccines might induce some NMDs, mainly in adults. The age distribution and gender characteristics of affected patients may differ based on the NMD type. About two-thirds of the cases probably occur in less than two weeks from the vaccination.
Non-nilpotent Leibniz algebras with one-dimensional derived subalgebra
Authors: Bartolo Alfonso Di , Rosa Gianmarco La , Mancini Manuel 
Published: August 2023

Abstract

In this paper we study non-nilpotent non-Lie Leibniz F-algebras with one-dimensional derived subalgebra, where F is a field with char(F) ≠ 2. We prove that such an algebra is isomorphic to the direct sum of the two dimensional non-nilpotent non-Lie Leibniz algebra and an abelian algebra. We denote it by Ln, where n = dimF Ln. This generalizes the result found in [11], which is only valid when F = C . Moreover, we find the Lie algebra of derivations, its Lie group of automorphisms and the Leibniz algebra of biderivations of Ln. Eventually, we solve the coquecigrue problem for Ln by integrating it into a Lie rack.

Abstract
Vagus nerve stimulation (VNS) is a therapeutic option in drug-resistant epilepsy. VNS leads to ≥ 50% seizure reduction in 50 to 60% of patients, termed "responders." The remaining 40 to 50% of patients, "non-responders," exhibit seizure reduction < 50%. Our work aims to differentiate between these two patient groups in preimplantation EEG analysis by employing several Entropy methods. We identified 59 drug-resistant epilepsy patients treated with VNS. We established their response to VNS in terms of responders and non-responders. A preimplantation EEG with eyes open/closed, photic stimulation, and hyperventilation was found for each patient. The EEG was segmented into eight time intervals within four standard frequency bands. In all, 32 EEG segments were obtained. Seven Entropy methods were calculated for all segments. Subsequently, VNS responders and non-responders were compared using individual Entropy methods. A total of 59 patients with epilepsy who were treated with VNS were identified. VNS responders and non-responders differed significantly in all Entropy methods except Approximate Entropy. Spectral Entropy revealed the highest number of EEG segments differentiating between responders and non-responders. The most useful frequency band distinguishing responders and non-responders was the alpha frequency, and the most helpful time interval was hyperventilation and rest 4 (the end of EEG recording).

Abstract
Background
Cream cheese analogue cheese is prepared using the substitutes of dairy fats and proteins partially or completely. Cream cheese analogue is easy to prepare as it requires less manufacturing time and man power. It also meets the specifications and requirements of the retailers as well as the consumers. Cream cheese analogue is a soft cheese with a slightly sweet and pleasantly tangy taste.
Methods
Cream cheese analogue ingredients are purchased carefully keeping in mind the required specifications. For the above mentioned research, different samples of cream cheese (T0, T1, T2 and T3) were manufactured with standardized fat and protein and the moisture was maintained at 50–55% during these trials. All ingredients were added in a large container for mixing and cooking (Pasteurization) for 1–2 minutes at 75°C and homogenized for 5–6 minutes with the help of a hand mixture until specific shine appeared in the sample. Samples were then shifted in to another container and allowed to attain temperature between 20–25°C. After that, samples were incubated with the addition of mesophilic culture until desired pH (4.6–4.7) was achieved. Later samples were heated at 50–55°C for 2–3 minutes placed in a muslin cloth and left overnight for whey drainage. Chemical analysis and Sensory evaluation were performed using different parameters and scales.
Results
Sample prepared using 75% dairy cream and 25% cocoa butter substitute fat (T1) showed good results. T1 had better consistency and spread ability which was considered desirable characteristics of cream cheese. This research proved the cost effective as cream cheese prepared with plant based fat which made its production viable at industrial level.
Conclusion
Cream cheese which was made from dairy fat and cocoa butter substitute fat 75% and 25% respectively had more springiness, smoothness and gumminess and also had more pleasant taste, color, flavor and aroma then other samples. This product can be used in future in Pakistan.
Study on the Deformation Effects of Foundation Pit Retaining Piles in the Influence Zone of the Footwall Affected by Reverse Fault
Authors: Niu Yungang , Wang Qiongyi , Ma Fenghai 
Published: August 2023

Abstract
In order to investigate the deformation characteristics of the retaining piles in the footwall affected by reverse fault, this study focuses on a case study of a foundation pit project in Shenzhen City, using numerical simulation methods. By analyzing the deformation characteristics of the retaining piles under reverse fault and investigating the influence of different fault slip amounts, dip angles, and positions on the pile deformation, sensitivity analysis and orthogonal experiments of fault parameters were conducted. The research results show that the deformation of the retaining piles under reverse fault exhibits an increasing trend, with the center of gravity shifting upward. Regarding the deformation impact, the upper part of the pile shows significantly larger deformation than the lower part, especially at the pile top. The overall deformation of the pile exhibits an approximate spoon-shaped curve, with the maximum deformation occurring in the middle to upper part of the foundation pit. The deformation of the pile is directly proportional to the fault slip amount and dip angle, while it is inversely proportional to the distance from the fault to the pit. Furthermore, the maximum deformation rate r(ΔZmax/Δ) increases non-linearly with increasing fault slip amount and dip angle, and decreases non-linearly with increasing distance from the fault to the foundation pit. Through sensitivity analysis of fault slip amount, dip angle, and position on the maximum deformation of the retaining pile, it is found that the dip angle has the greatest influence on deformation, followed by the slip amount, while the fault position has the least influence. By fitting the data from 64 orthogonal experiments, a good linear relationship is established between the maximum deformation Uhm of the retaining pile and the index η(\(\frac{{\theta \pi T}}{{{{180}^^\circ }S}}\) ). Furthermore, a predictive model is developed for the maximum deformation of the retaining pile in the influence zone of the footwall affected by reverse fault. This study provides valuable references for controlling deformations in foundation pit projects in reverse fault areas and holds significant importance for rational design and construction. The research findings contribute to reducing geological hazards, ensuring engineering safety, and promoting the sustainable development of foundation pit projects. Moreover, these contributions play a positive role in minimizing environmental impacts, resource consumption, and advancing the sustainability of engineering practices.

Published: August 2023

Abstract
Background
Wheat, a crucial food crop in China, is highly vulnerable to drought stress throughout its growth and development. WRKY transcription factors (TFs), being one of the largest families of TFs, play a vital role in responding to various abiotic stresses.
Results
In this study, we cloned and characterized the TF TaWRKY31 from wheat. This TF, belonging to the WRKY II family, contains a WRKYGQK amino acid sequence and a C2H2-type zinc finger structure. TaWRKY31 is expressed with tissue specificity and is responsive to abiotic stresses in wheat. TaWRKY31 protein is localized in the nucleus and can function as a TF with transcription activating activity at the N-terminus. Results showed that the wheat plants with silenced strains (BSMV: TaWRKY31-1as and BSMV: TaWRKY31-2as) exhibited poor growth status and low relative water content when subjected to drought treatment. Moreover, the levels of O2·−, H2O2, and malondialdehyde (MDA) in the plants increased, while the activities of antioxidant enzymes (superoxide dismutase, peroxidase, and catalase) decreased. The expression levels of TaSOD(Fe), TaPOD, TaCAT, TaDREB1, TaP5CS, TaNCED1, TaSnRK2, TaPP2C, and TaPYL5 all decreased. The heterologous overexpression of TaWRKY31 in Arabidopsis decreased H2O2 and MDA content, stomatal opening, and water loss. Furthermore, an increase in resistance oxidase activity, germination rate, and root length in the TaWRKY31 transgenic Arabidopsis was observed. Lastly, the expression levels of AtNCED3, AtABA2, AtSnRK2.2, AtABI1, AtABF3, AtP5CS1, AtSOD(Cu/Zn), AtPOD, AtCAT, AtRD29A, AtRD29B, and AtDREB2A increased in the transgenic plants.
Conclusions
Our findings indicate that TaWRKY31 enhances drought resistance in plants by promoting the scavenging of reactive oxygen species, reducing stomatal opening, and increasing the expression levels of stress-related genes.

AbstractVehicular networking in smart autonomous connected vehicle communications evolved with high mobility and due to high dynamics in an urban environment, new challenges are addressed by academicians and researchers for providing better support. Dynamic changes of vehicular nodes position, routing in Vehicular Adhoc Network (VANET) using existing traditional networking routing algorithms may not provide optimal solution for efficient communication. Also predicting or forecasting traffic flow in VANET can be improved through sharing traffic information in real-time using intelligent transportation systems. In this paper we proposed modified reinforcement learning algorithm that supports for optimal route identification for dynamically disconnected vehicles in urban environment by considering its previous state and predicts flow of traffic generated by vehicles in various time interval. Experimental result shows better performance in routing parameters like packet delivery ratio, routing overhead, latency and predicting traffic flow by proposed algorithms achieves significant accomplishments comparing to existing algorithms.

Published: August 2023

Abstract
Background
We report a rare case of high-energy blunt traumatic vertebro-vertebral arteriovenous fistula (VV-AVF) with retropharyngeal hematoma (RH) following C2 vertebral fracture after a traffic accident. Although there is currently no established guideline to treat blunt traumatic VV-AVF, effective transarterial embolization to sacrifice the parent artery succeeded in complete obliteration of the VV-AVF with no ischemic complications.
Case presentation
A 74-year-old woman injured in a traffic accident was transferred to our hospital by ambulance. On arrival, she complained of neck pain and headache. Her respiration and circulation were stable. Computed tomography (CT) revealed a slight subarachnoid hemorrhage, cervical spinal fracture (C2), rib fracture, and thoracic spinal compression fracture. Contrast-enhanced CT showed suspected dissection of her right vertebral artery (VA) at the C2 level. The next day, extravasation from her right vertebral artery at the C2 level was suspected on magnetic resonance angiography, and a thick RH was revealed on a T2-weighted magnetic resonance image. The angiographic study indicated a diagnosis of a high-flow VV-AVF at the C2 level. Transarterial embolization with coils was performed to sacrifice the parent artery, and n-butyl-2-cyanoacrylate injection significantly reduced flow through the fistula, which succeeded in completely obliterating the fistula at one month after the procedure.
Conclusions
VV-AVF caused by high-energy blunt trauma is extremely rare, but an upper cervical spine injury may trigger it, and RH may sometimes also occur. Transarterial coil embolization of the parent artery to completely obliterate the fistula is generally considered a reliable treatment in the acute stage. The current lack of a treatment guideline requires the accumulation of additional knowledge on the treatment of high-energy blunt traumatic VV-AVF.

Abstract
During the COVID-19 epidemic, due to high risk from travel and gathering in groups, the Ministry of public Health in Qatar decided to offer home delivery of medication. We aim to investigate the satisfaction and preference of patients with chronic diseases who have utilized the new home delivery services from Health Centers. A descriptive cross-sectional study was used exploratory questionnaire to assess the preference of patients in terms of delivery of their medications. Out of 656 participants, 98.78% of the patients suffer from chronic diseases. Males (54%) were slightly more than the females (46%) and most were University graduates (68%). Age wise 68% were over 40 with majority 35% 41–50 years. Around 72% took an average of 10–30 minutes to travel from home to the health center. Majority (62.65%) preferred face to face in the way the services were arranged and information provided, ease of contacting to provide services (55%), sorting out queries and problems (61%), complaints or concerns handled (59%), receiving the drugs without affecting the conditions of transportation and storage of medications (58%), the accuracy and completeness of supplies delivered (58%), the helpfulness and courtesy of the person delivering the medications (57%), the quality of services and advice received (59%). Majority felt face to face was more cost efficient than the home delivery service (64%). Overall, the views of patients regarding the home delivery services were generally positive, but some patients still held their preference of face-to-face interactions over certain aspects of the service provision. Costs have also been a concern after its introduction which needs to be addressed when considering future aspects of the service. This service may play a major role in the future to improve accessibility for the community and reduce unneeded visits to the health centers.
Assessment of stature in Iron Age populations of South Africa
Authors: Steyn Maryna 
Published: August 2023

Abstract
Worldwide and in South African Stone Age contexts, much research has been done on the relationship between stature of past populations and general well-being, as well as trends and patterns in stature through time. This research aimed at collating and assessing all available stature and long bone data for Bantu-speaker individuals living in the South African Iron Age. Data for only 25 female and 32 male individuals, dating from circa AD 550 to AD 1823, could be found. In general, methods used to reconstruct stature were inconsistent and data were poorly reported. From the available data, no clear trends or patterns in stature through time could be observed and stature seems to be on a par relative to those of early 20th century individuals. Recommendations are made as to which methods to use in stature estimations in this context. The data provided in this research can serve as reference material for future similar studies and can assist in interpreting individual stature estimations from bioarchaeological research in the region.
Multidimensional engineering of Saccharomyces cerevisiae for improved vanillin synthesis
Authors: Mo Qiwen , Yuan Jifeng 
Published: August 2023

Abstract
Background Vanillin represents one of the most widely used flavoring agents in the world. However, microbial synthesis of vanillin is hindered by the host native metabolism that could rapidly degrade vanillin to the byproducts.
Results Here, we report that the industrial workhorse Saccharomyces cerevisiae was engineered by systematic deletion of oxidoreductases to improve the vanillin accumulation. Subsequently, we harnessed the reduced aromatic aldehyde reduction (RARE) yeast platform for de novo synthesis of vanillin from glucose. We investigated multiple coenzyme-A free pathways to improve vanillin production in yeast. The vanillin productivity in yeast was enhanced by multidimensional engineering to optimize the supply of cofactors (NADPH and S-adenosylmethionine) together with metabolic reconfiguration of yeast central metabolism. The final yeast strain with overall 24 genetic modifications produced 365.55 ± 7.42 mg l-1 under shake-flasks, which represents the highest vanillin titer from glucose achieved to date.
Conclusions The success of vanillin overproduction in budding yeast showcases the great potential of synthetic biology for the creation of suitable biocatalysts to meet the requirement in industry. Our work lays a foundation for the future implementation of microbial production of aromatic aldehydes in budding yeast.

Published: August 2023

Abstract
Ni(OH)2-based materials are widely concerned as advanced energy storage materials, but their poor cycle performance makes their practical application and commercialization slow. Herein, Ni(OH)2@g-C3N4 core-shell (crystal and amorphous) heterojunctions are synthesized. These heterojunctions enhance the specific surface area and ionic diffusion, especially the heterojunction formed by the amorphous shell shows more robust performance. It is found that this heterojunction mainly uses the fast reversible Faraday reaction of battery type as the primary energy storage mechanism. The as-prepared core-shell heterojunction showed nearly double specific capacitance and excellent cycle stability (578.54 F g-1 and 109.30% retentions after 5,000 cycles) over pristine Ni(OH)2 (285.75 F g-1 and 101.55% retentions after 5,000 cycles). Finally, an efficient hybrid supercapacitor is developed via Ni(OH)2@g-C3N4 //AC, which combines the advantages of the battery and supercapacitors. The hybrid supercapacitor device shows sparkled capacitance (311.83 F g-1) and striking cycle performance (84.33% retentions after 10,000 cycles). In particular, the energy density of 77.97 Wh kg-1 can still be provided while maintaining the power density of 1201.08 W kg-1. This emerging heterostructure offers new insight into Ni(OH)2-based materials in energy applications.
