Authors: Ding Jian , Xu Zhiguang 
Published: June 2023

Abstract
In order to reduce energy dissipation and alleviate the energy crisis, this paper proposes an absorption mode of distribution network with distributed power supply. First of all, the starting power coefficient and cutting off power coefficient are set to reflect the efficiency of the inverter and obtain the active output power of the photovoltaic system. Then, the Gaussian iterative algorithm is used to calculate the power flow of the distribution network, which forms a model along with the branch switch to complete the variables optimization under the conditions that all power conversion elements are removed from the system and the security constraint is satisfied. Afterwards, through the apparent power of the distribution network node, the single feeder is transformed into two feeders to ensure the fixed voltage at the front end of the line and make the node voltage rise and exceed the limit. Meanwhile, the active power and reactive power are provided for distribution network to reduce the feeders voltage loss, the reasonable regulation measures are used to stabilize the voltage, and the constant power factor and voltage amplitude of the network connection point are added to address voltage over limit and lighten the influence of increasing distributed power on voltage rising. Finally, the size of voltage amplitude is referred to determine the reactive power, so as to realize reasonable absorption of distribution network. The analysis results show that the voltage regulation measures proposed significantly improve the overall absorption capacity of the power supply, with the capacity increased by 0.54MW and 0.2MW respectively.

Published: June 2023

Abstract
In recent years, the frequent occurrence of earthquakes, landslides, debris flow and other geological disasters worldwide is endangering people's production and life, which not only causes serious damage to infrastructure, but also creates a certain degree of fear for people. Geological disaster is an open nonlinear complex system, which has extraordinary complex geological process, formation conditions, and causes. Therefore, it makes difficulty in capturing the dynamic information and searching for the global optimal solution. Meanwhile, traditional geological disaster warning system has the deficiencies of single disaster warning and low accuracy. In order to improve the level of early warning and detection of geological disasters, this paper combined the genetic algorithm with superior performance and Support Vector Regression (SVR) algorithm to establish a feasible and credible early warning and monitoring model for geological disasters. The experimental results show that the early warning and monitoring model proposed in this paper can greatly improve the ability of geological disaster prevention and early warning, and greatly improve the level of disaster prevention and early warning, with good engineering application value.

Abstract
A LoRa (Long Range Radio) based smart home product interaction system for the elderly is designed to solve the problem of reliability communication in the collection and information transmission of smart home environment parameters, device status parameters and the complex layout of communication lines inside smart devices. A privacy-preserving data aggregation scheme without a trusted authority center is proposed to address the privacy protection problem in the process of Internet of things (IoT) data collection. Firstly, without relying on the trusted authority center, the key exchange algorithm is used to generate shared secret keys and construct encryption keys among terminal devices to ensure the privacy of reported data; secondly, a fault tolerance mechanism is designed according to Carmichael’s theorem, so that the control center can still aggregate the received data when the terminal device fails or the network connection is wrong; in addition, the batch In addition, the integrity of the reported data is ensured by means of batch verification. Finally, the theoretical analysis proves the correctness and security of the scheme in this paper. The performance experiments show that the required computational overhead is lower compared to existing schemes, while some communication overhead is increased in order to have fault tolerance and to improve the verification efficiency of digital signatures. The application of this system will highlight the main position of the elderly, so that they can truly experience and accept the benefits of smart home for their lives and improve their quality of life.

Abstract
China’s tailing pond online monitoring technology started late, and the tailing pond is located in a harsh working environment, for the limitations of traditional manual monitoring of tailing pond, combined with the actual situation of Zhenhua Mining tailing pond. This paper constructs a risk monitoring index system and online monitoring early warning model based on (Language Model - Back Propagation, LM-BP) neural network to quantitatively assess tailing pond safety risks and analyze and judge safety risk trends. We extracted common indicators of regional tailing ponds, combined with meteorological data to establish a regional safety risk assessment model, integrated vulnerability of disaster-bearing bodies, environmental sensitivity and other influencing factors, realized regional risk coupling analysis, and dynamically built a risk cloud map. Based on the perspective of safety risk prevention and control, the integrity and accuracy of monitoring data are analyzed, the causes of early warning are inverted, alarm disposal mechanisms are established, and closed-loop management of early warning is realized to provide scientific auxiliary decision-making support for tailing pond safety supervisors.

Abstract

Introduction
Because of the activities and effects they induce, hormones are prohibited for use for anabolic purposes in farm animals intended for slaughter, which is regulated in the European Union by relevant legal provisions. Therefore, there is an obligation to monitor residues of hormones in animals and food of animal origin to ensure consumer safety. A hormone banned but used formerly for fattening cattle, stanozolol, and its metabolite 16β-OH-stanozolol are synthetic compounds that belong to a large group of steroid hormones. This study investigates residues of these compounds in animal urine.

Material and Methods
From 2006–2022, 2,995 livestock urine samples were tested for stanozolol residues in Poland as part of the National Residue Monitoring Programme. A liquid chromatography–tandem mass spectrometry method to determine stanozolol and 16β-OH-stanozolol in animal urine was developed and validated according to the required criteria. Urine sample analysis was based on enzymatic hydrolysis of hormones potentially present in it to the free form, extraction of them from the sample with a mixture of n-hexane and butyl alcohol, purification of an extract on an NH2 amine column and finally, instrumental detection.

Results
The apparent recovery and precision parameters of the developed method were in line with the established criteria, while its decision limits CCα and detection capabilities CCβ were lower than the recommended concentration for analytical purposes set at 2 μg L−1 (valid until December 15, 2022; currently set as 0.5 μg L−1).

Conclusion
All examined samples were compliant with the evaluation criteria.
Design and manufacturing of a head mask for fixation in stereotactic radiosurgery by the Gamma Knife® Icon™
Authors: Faraj Moneer K. , Al-Musawi Mustafa Salih , Ali Abdulameer Tabarek 
Published: June 2023

Background:
This study evaluates an alternative to the classical method of head fixation during Gamma Knife radiosurgery using a Leksell head frame. In the Gamma Knife® Icon™ model, a new method of head fixation is used by utilizing a thermal molded polymer mask that takes the shape of the patient’s head before fixing the head to the table. However, this mask is for single use and quite expensive.

Methods:
We describe a new, very economical method to fix the head of the patient during radiosurgery. We used commercial, quite cheap material [polylactic acid (PLA)] plastic and made a 3D printing model for the patient’s face, taking special measurements to put this mask and fix it on the Gamma Knife. The actual material cost is only $4 (100 times less than the original mask cost).

Results:
The new mask efficiency was tested using the movement checker software, the same one used to measure the efficiency of the original mask.

Conclusion:
The newly designed and manufactured mask is quite effective for use with the Gamma Knife® Icon™, with a much lower cost, and it can be manufactured locally.

Published: June 2023

Background:
We previously demonstrated the usefulness of periorbital electrodes in supplemental recording to detect epileptiform discharges in patients with mesial temporal lobe epilepsy (MTLE). However, eye movement may disturb periorbital electrode recording. To overcome this, we developed mandibular (MA) and chin (CH) electrodes and examined whether these electrodes could detect hippocampal epileptiform discharges.

Methods:
This study included a patient with MTLE, who underwent insertion of bilateral hippocampal depth electrodes and video-electroencephalographic (EEG) monitoring with simultaneous recordings of extra- and intracranial EEG as part of a presurgical evaluation. We examined 100 consecutive interictal epileptiform discharges (IEDs) recorded from the hippocampus and two ictal discharges. We compared these IEDs from intracranial electrodes with those from extracranial electrodes such as MA and CH electrodes in addition to F7/8 and A1/2 of international EEG 10-20 system, T1/2 of Silverman, and periorbital electrodes. We analyzed the number, rate of laterality concordance, and mean amplitude of IEDs detected in extracranial EEG monitoring and characteristics of IEDs on the MA and CH electrodes.

Results:
The MA and CH electrodes had nearly the same detection rate of hippocampal IEDs from other extracranial electrodes without contamination by eye movement. Three IEDs, not detected by A1/2 and T1/2, could be detected using the MA and CH electrodes. In two ictal events, the MA and CH electrodes detected the ictal discharges from the hippocampal onset as well as other extracranial electrodes.

Conclusion:
The MA and CH electrodes could detect hippocampal epileptiform discharges as well as A1/A2, T1/T2, and peri-orbital electrodes. These electrodes could serve as supplementary recording tools for detecting epileptiform discharges in MTLE.
Medullary brainstem gliomas in an adult: A rare case report and challenging tumor
Authors: Aleid Abdulsalam Mohammed , Alaethan Mohammed Hijji , Alsaati Ahmed Abdulaziz , Alhejji Murtadah Hassan , Ali Alkathem Jafar 
Published: June 2023

Background:
Medullary brainstem lesions are rare tumors that are challenging to treat due to their location in the brainstem, which controls vital functions such as breathing, heart rate, and blood pressure. While the most common subtype is the aggressive diffuse intrinsic pontine glioma, other subtypes exist, including focal brainstem gliomas and cervicomedullary gliomas. The prognosis for patients with brainstem gliomas is generally poor, and treatment options are limited. Early detection and treatment are crucial to improve outcomes for patients with these tumors.

Case Description:
In this case report, the authors describe a 28-year-old male from Saudi Arabia who presented with headaches and vomiting. Imaging studies and clinical examination revealed a high-grade astrocytoma medullary brainstem lesion. The patient underwent radiation therapy and chemotherapy, effectively controlling tumor growth and improving his quality of life. However, a residual tumor remained, and the patient underwent neurosurgery to resect the remaining tumor was successful in removing the tumor, and the patient showed significant improvement in his symptoms and overall health.

Conclusion:
This case highlights the importance of early detection and treatment of medullary brainstem lesions. While radiation therapy and chemotherapy are primary treatment options, neurosurgery may be necessary to resect residual tumors. In addition, cultural and social factors may need to be considered in managing these tumors in Saudi Arabia.
A case of infectious intracranial aneurysm that formed and ruptured within a few days after occlusion of the proximal middle cerebral artery by infective endocarditis
Authors: Yanagawa Taro , Ikeda Shunsuke , Yoshitomi Shota , Shibata Aoto , Ikeda Toshiki 
Published: June 2023

Background:
Embolic cerebral infarction and infectious intracranial aneurysms (IIAs) are well-known central nervous system complications of infective endocarditis (IE). In this report, we describe a rare case of cerebral infarction caused by the occlusion of the M2 inferior trunk due to IE, followed by the rapid formation and rupture of IIA.

Case Description:
A 66-year-old woman was admitted to the hospital with a diagnosis of IE and embolic cerebral infarction after being brought to the emergency department with a 2-day history of fever and difficulty walking. After admission, she was immediately started on antibiotic therapy. Three days later, the patient suddenly became unconscious, and a head computed tomography (CT) scan showed massive cerebral hemorrhage and subarachnoid hemorrhage. Contrast-enhanced CT showed a 13-mm large aneurysm in the left middle cerebral artery (MCA) bifurcation. An emergency craniotomy was performed, and intraoperative findings revealed a pseudoaneurysm at the origin of the M2 superior trunk. Clipping was considered difficult, so trapping and internal decompression were performed. The patient died on the 11th day after surgery due to the worsening of her general condition. The pathology of the excised aneurysm was consistent with a pseudoaneurysm.

Conclusion:
IE may cause occlusion of the proximal MCA and rapid formation and rupture of IIA. It should be noted that the location of IIA may be a short distance away from the occlusion site.

Published: June 2023

Background Iron deficiency anemia (IDA) remains one of the most common diet-related micronutrient deficiency disorders in the world. Although iron supplementation can effectively improve iron status, it is often a short-term solution to this endemic, chronic health problem. Lucky Iron Fish® (LIF) offers a novel, long-term approach to treat IDA that can be easily utilized in regions of the world where IDA is most prevalent. While the beneficial use of LIF for household preparation of meals has been demonstrated, its use in quantity food production has not been investigated. The purpose of this study was to develop methodology for large-scale iron fortification of cooking water and to assess changes in hemoglobin and hematocrit values in school-going children following 8 months of receiving iron-fortified school lunches prepared with LIF. Methods Laboratory studies were conducted to develop the protocol to prepare iron fortification of cooking water using LIF. Study participants were school-going children from economically, disadvantaged families attending private schools in Jocotenango, Guatemala. Baseline measures (weight, height, hemoglobin, and hematocrit) were taken at the start and completion of the academic calendar. The sample was divided into quintiles based on pre-hemoglobin and hematocrit values where quintile 1 had the lowest baseline hemoglobin and hematocrit values and quintile 5 had the highest baseline hemoglobin and hematocrit values. Paired t-tests were used to determine if there were overall significant pre- and post-differences in iron status values by quintile groupings. Results A total of 286 (77%) of children between the ages of 5 – 16 (y) completed the study. Post- hemoglobin values were significantly higher than pre-hemoglobin values for those in quintile 1, whereas post-hematocrit values significantly increased for quintiles 1 and 2. Conclusions Study results suggest that LIF can be used to prepare large quantities of food and that regular consumption of iron-fortified school lunches can improve iron status in children with marginal status. Equally important is the finding that iron-fortified meals do not negatively impact those with healthy iron values.
