Authors: Zhao Pengfei , Wu Jiuwei , Wang Yu , Li Yong , Guan Guoying 
Published: December 2023

Abstract
ThO2 can produce many useful elements after accelerator bombardment, such as Actinium-225, Radium-223, Molybdenum-99, Iodine-131, Strontium-90, etc. There are many methods for measuring heavy elements such as thorium, but most of them are complicated to operate. Spectrophotometry has the advantages of simple sample preparation and low operation difficulty, and can be used as a quantitative analysis method for thorium and other heavy elements. ThO2 ws dissolved with nitric acid and hydrogen fluoride, and the concentration of T(IV) in ThO2 solution was quantitatively analyzed with Arsenazo III as the chromogenic agent. Under the environment of 2 mol/L hydrochloric acid solution and 0.1 g/L Arsenazo III solution, the coordination ratio of Arsenazo III and Th(IV) is 5:2 under the experimental conditions determined by the finite logarithm method. The maximum absorption wavelength before and after color development is 534.0 nm and 663.2 nm, respectively, and the contrast is 129.2 nm. The method in 0.2∼5.0 mg/L in accordance with Lambert-Beer’s law, the standard curve equation A = 0.00176C+0.06641, R2 = 0.99981. The molar absorption coefficient of 1.64 × 104. Method detection limit is 0.31 μg/L, and quantitative limit is 0.97 μg/L. The method is stable within 4 h. The recovery is 97.33%∼104.03%, and the largest standard deviation is 0.32%. The method was compared with GB/T 12690.12-2003, the process was simplified and the results were basically consistent.
Alternative Approach to Copenhagen Interpretation
Authors: Kim Pil-Jae 
Published: December 2023

Abstract
In this study, a double-slit experiment was simulated with only classical-mechanics assumptions to demonstrate that the phenomena associated with this experiment can be explained by classical mechanics. The experiment was conducted with the particle nature intact, by performing observations that did not affect the particle motion while recording the particle position at each simulation step. Only one experimental particle was assumed per session to prevent external effects. Nevertheless, wave patterns, which have previously been thought to occur only quantum-mechanically, were observed on the inspection plate. This study focused on proving that classical mechanics can explain the double-slit wave pattern.
Cyber-Physical Secure Observer Synthesis under Model Mismatch and Unknown Input
Authors: Tahmasbi Mohammad , Farbod Alireza 
Published: December 2023

Abstract
This paper adresses a proportional-integral observer under cyber-physical system setting. This Proportional-Integral Observer (PIO) is designed to estimate the states of a linear system in presence of model mismatch, external disturbance, and unknown input. Accuracy and stability of a observer strongly depend on the accuracy of model and output measurements. In reality, these conditions are very rare, therefore it is required to develop a method for designing robust observers in presence of uncertainties, external disturbances and unknown input. A Lyapunov method and Linear Matrix Inequality (LMI) theory have been proposed to design the observer and to illustrate the stability of it. The stability of the proposed PI observer is proved and with numerical examples its efficiencies has been shown.

Published: December 2023

Abstract

Introduction:
Cesarean scar pregnancy (CSP) is a rare but potentially life-threatening form of ectopic pregnancy which incidence has been constantly raising during the last decades. The aim of this study was to describe the epidemiological characteristics of CSP in our population and to investigate the impact of different treatments on the maternal outcomes and prognosis.
Patients and methods:
This was a retrospective study including all patients diagnosed with CSP and who were admitted in our maternity between January 2010 and December 2020. Data were collected from the patients’ medical records. We compared outcomes (hospital stay duration, serum BHCG levels, complications, new pregnancy) in 2 groups: group 1 was treated with systemic injection of methotrexate (MTX) associated with dilatation curettage (DC) and group 2 was managed with uterine artery embolization (UAE) and DC.
Results:
The mean age was 33.5 years old. Most of patients (80%) reported history of 2 or more previous cesarean sections. The mean gestational age at diagnosis was 8 weeks. Patients presented mostly with isolated amenorrhea. The mean βHCG serum level at admission was 52352.4 milliunits/mL. The diagnosis was made on ultrasonographic examination in all cases. The Management of CSP in group 1 was associated with a significantly shorter resolution time of serum βHCG levels (p = 0.006). A shorter hospital stay duration was also reported in group 1 but with no statistical significance (p = 0.31). Complications were more observed in group 2 but with no statistical significance (p = 0.61).
Conclusion:
We concluded that UAE associated with an ultrasound-guided DC might be an interesting option for the management of CSP. An early and appropriate diagnostic with identification of cases at higher risk is necessary to reduce complications.
Percolation of the Past in the Middle Ages? Case-Study of the Necropolis Ravna–Slog near Knjaževac
Authors: Milosavljević Monika , Ilijić Bojana 
Published: December 2023

The things surviving into the present from the previous epochs have under- gone the processes of selection and fragmentation.Therefore, the elements from the past that penetrate into another time are fragmented and represent a (material) memory of the previous practices, events, lifestyles, or an unknown that easily raises mystical ideas about the other worlds. Gavin Lucas describes this phenomenon of past penetrating into the present as percolation (lat. percolatio). The term is derived from chemistry, where it denotes filtration or drainage, i. e. the passage of fluid through a filter and separation of substances
The archaeological perspective is capable to deal with the coexistence of sets of material culture from various times in thepresent. On the other hand, the polychrony of archaeological assemblages has often been purified and separated through scientific practices – as if the present is not always filled with the past. The interpretation of the mutual relations among the past times andtheir usage/ meaning in the new contexts is not susceptible to simple solutions. It is hard to explain why a certain event or an objectdisappears from the memory and usage, while others endure into the present or occur again.
The paper analyses the Early Medieval funerary contexts from the necropolis Ravna–Slog in which the artefacts originating from the Roman or prehistoric periods are registered along with the Medieval ones. The similar phenomenon is registered in the case ofthe Avar-Period graves. The mixed contexts from Ravna are interpreted as the consequence of the need to construct the link to the past, with the aim to legitimize the presence in the new territory.
Synchronous Bilateral Brachial Blood Pressure Measurements Increased
Orthostatic Hypotension Detection in the Elderly
Authors: Zhang Jianying , Gao Xia , Ma Benxu , Liu Lili , Gao Huanmin 
Published: December 2023

Background:
Orthostatic hypotension (OH) is a common clinical sign, but its detection rate is low, and it is difficult to repeat because there is no standardized screening method
available.

Aim:
This study aimed to establish a method for detecting blood pressure and assess whether it
could increase the OH detection rate in the elderly.

Methods:
From May to October, 2022, 178 patients with symptomatic OH and 286 subjects with
asymptomatic OH were selected. BP from the bilateral brachial artery was measured using two
electronic sphygmomanometers on both arms at the same time, in the order of supine, sitting,
and standing at 0-3 min. OH should meet 20/10 mmHg, standing BP minus sitting BP. The OH
detection rates were calculated and compared. The symptomatic OH group was more often older,
slimmer, had lower ADL scores, and contained fewer smokers (all P< 0.05).

Results:
The detection rate of the symptomatic OH group using the modified method was
59.55%, which was higher than that of the routine method (34.83% vs. 59.55%, P<0.05). The detection rate using the modified method in the OH group with asymptomatic OH was 20.63%,
which was higher than that of the routine method (20.63% vs. 5.59%, P< 0.01).

Conclusion:
Synchronous measurement of bilateral brachial artery BP in supine, sitting, and
standing positions increased the detection rate of OH in the elderly.
Role of Complement-dependent Cytotoxicity Crossmatch and HLA Typing
in Solid Organ Transplant
Authors: Tiwari Arpit , Mukherjee Sayali 
Published: December 2023

Background:
Solid organ transplantation is a life-saving medical operation that has
progressed greatly because of developments in diagnostic tools and histocompatibility tests.
Crossmatching for complement-dependent cytotoxicity (CDC) and human leukocyte antigen
(HLA) typing are two important methods for checking graft compatibility and reducing the risk
of graft rejection. HLA typing and CDC crossmatching are critical in kidney, heart, lung, liver,
pancreas, intestine, and multi-organ transplantation.

Methods:
A systematic literature search was conducted on the internet, using PubMed, Scopus,
and Google Scholar databases, to identify peer-reviewed publications about solid organ
transplants, HLA typing, and CDC crossmatching

Conclusion:
Recent advances in HLA typing have allowed for high-resolution evaluation,
epitope matching, and personalized therapy methods. Genomic profiling, next-generation
sequencing, and artificial intelligence have improved HLA typing precision, resulting in better
patient outcomes. Artificial intelligence (AI) driven virtual crossmatching and predictive
algorithms have eliminated the requirement for physical crossmatching in the context of CDC
crossmatching, boosting organ allocation and transplant efficiency. This review elaborates on the
importance of HLA typing and CDC crossmatching in solid organ transplantation.

Introduction: Post-COVID-19 syndrome can be seen from the radiological findings on the chest X-ray (CXR). However, limited studies compared CXR changes in post-COVID-19 patients based on their severity.
Methods: Thirty-three post-hospitalized COVID-19 patients who came to the Long COVID Clinic at UGM Academic Hospital were divided into mild-moderate and severe-critical groups. The CXR were taken during hospital admission, in the 4th week, and in the 8th week. CXR images were assessed with the Brixia Score method.
Results: The Brixia score in the mild-moderate group (n = 17) and severe-critical (n = 16) group showed a trend of change, which increased in the 4th week and decreased in the 8th week. However, there were no significant changes between the two groups during hospital admission, in the 4th week, and in the 8th week. The Brixia score during hospital admission and in the 8th-week follow-up in the mild-moderate group was significantly lower than that of the severe-critical group. Clinically, the mean Brixia score in the mild-moderate group ranges from mild pneumonia, while the severe-critical group ranges from moderate pneumonia.
Conclusion: There is no significant resolution of the CXR until the 8th-week follow-up in post-COVID-19 infection patients with mild-moderate and severe-critical severity. However, the CXR during hospital admission and the 8th week is better in post-COVID-19 infection patients with mild-moderate severity.

CURVULARIA PULMONARY FUNGAL INFECTION ASSOCIATED WITH IMMUNOCOMPROMISED PATIENT: HOW CT SCAN COULD HELP IN MAKING DIAGNOSIS
Authors: Kristina Paskalita Kero  , Dini Rachma Erawati  
Published: December 2023

Pulmonary fungal infections can be found in immunocompetent and immunocompromised patients. The Curvularia species of fungi are rarely seen in humans. These fungi can be clinically significant and cause a range of disease processes, particularly in immunocompromised patients. We present a 24-year-old male patient diagnosed with SLE 5 years ago, complaining of fever five days before hospital administration concerning pneumonia. A CT scan revealed consolidation and multiple lung nodules compatible with a fungal pulmonary infection. The result of the sputum culture indicated Curvularia. A chest radiograph showed infiltrates with consolidation in the middle-lower lobes of both lungs. Early and second CT-scan findings revealed ground-glass opacity surrounding multiple irregular nodules (halo signs), cavitary nodules, and reverse halo signs. Afterward, the result of the patient’s sputum culture demonstrated fungal growth of the Curvularia species. The patient then underwent fungal treatment with fluconazole and voriconazole. The patient showed improvements, and a follow-up chest CT scan revealed the resolution of the lesion after fungal treatment. CT-scan examination, clinical condition, and microbiology culture can help diagnose Curvularia pulmonary fungal infection in immunocompromised patients.

Development of a Low-Cost, Open-Source LoRA-based SCADA System for Remote Monitoring of a Hybrid Power System for an Offshore Aquaculture Site in Newfoundland
Authors: Asgher Muhammad Nadeem , Iqbal Muhammad Tariq 
Published: December 2023

In this article a low-cost and open-source Internet of Things (IoT) based Supervisory, Control and Data Acquisition (SCADA) system for remote monitoring of the hybrid power system for an offshore aquaculture site is presented. The selected site is situated 2 km away from the coastline where there is no electrical utility infrastructure and limited communication options are available. The hardware of the designed system primarily consists of six field sensors, Arduino Leonardo as Remote Terminal Unit (RTU), LoRA (Long Range) gateway, cables, AC/DC current and voltage supplies. Arduino IDE, AWS, Influx DB, and Grafana provide the software support. The field sensors are responsible for measuring the solar, battery, inverter & generator currents, along with battery voltage and temperature. All of the field sensors except the temperature sensor send the data to RTU which further delivers it to The Things Network (TTN) cloud. With the help of influx DB, AWS cloud computing services, and Grafana, the data can be stored and visualized through interactive yet informative graphs. The graphs display the historical and live data of each sensor. Further, it also gives the option to set alarms and alerts on user-defined conditions to improve control over the hybrid power system. The complete hardware is assembled and tested in Memorial University’s Power lab. The developed system was supplied with variable current/voltage supplies and the data was logged for three continuous hours. However, the data can be stored for a much longer duration as per user’s requirement. The hardware and the results presented here are a testament that the proposed design system is capable of providing a remote monitoring solution for the offshore aquaculture site.

Robust Optimization Model for Internet Shopping Online Problems with Endorsement Costs in the Fashion Industry
Authors: Anjanette Olivia , Subartini Betty , Chaerani Diah 
Published: December 2023

Online business is a business activity carried out via the internet or digitally. Buying, selling, and advertising are done online through e-commerce, social media, or online shops. The products offered vary, including services, food, household needs, and fashion. Selling online is not limited by time and distance, and consumers can obtain information about products and services that can influence their decisions. At the same time, sellers also have the opportunity to advertise their products in a broader range by making endorsements. An endorsement is a form of advertising using well-known figures who are recognized, trusted, and respected by people. In this thesis, a model for optimizing the problem of online internet shopping with endorsement fees is formulated. This optimization model aims to maximize the profits gained by sellers in marketing their products online. In marketing products, there is uncertainty in the number of requests. To overcome this uncertainty, an approach is needed that can handle this uncertainty, namely Robust optimization. The Robust optimization model is solved using the polyhedral uncertainty set approach, resulting in a computationally tractable optimal solution. Keywords: internet shopping online; endorsement costs; robust optimization.

Published: December 2023

Abstract
The influence of artificial intelligence (AI) in smart cities has resulted in enhanced efficiency, accessibility, and improved quality of life. However, this integration has brought forth new challenges, particularly concerning data security and privacy due to the widespread use of Internet of Things (IoT) technologies. The article aims to provide a classification of scientific research relating to artificial intelligence in smart city issues and to identify emerging directions of future research. A systematic literature review based on bibliometric analysis of Scopus and Web of Science databases was conducted for the study. Research query included TITLE-ABS-KEY (“smart city” AND “artificial intelligence”) in the case of Scopus and TS = (“smart city” AND “artificial intelligence”) in the case of the Web of Sciences database. For the purpose of the analysis, 3101 publication records were qualified. Based on bibliometric analysis, seven research areas were identified: safety, living, energy, mobility, health, pollution, and industry. Urban mobility has seen significant innovations through AI applications, such as autonomous vehicles (AVs), electric vehicles (EVs), and unmanned aerial vehicles (UAVs), yet security concerns persist, necessitating further research in this area. AI’s impact extends to energy management and sustainability practices, demanding standardised regulations to guide future research in renewable energy adoption and developing integrated local energy systems. Additionally, AI’s applications in health, environmental management, and the industrial sector require further investigation to address data handling, privacy, security, and societal implications, ensuring responsible and sustainable digitisation in smart cities.
Comparisons Between Macedonian and A U.S. State’s Automobile Accident Insurance Law
Authors: Carrier Paul J. 
Published: December 2023

Abstract
This paper explores some of the basic similarities and differences between fault-based and no-fault systems of automobile accident insurance from the perspective of a U.S. state and the laws of Macedonia. The majorities of U.S. states have adopted an at-fault system of compensation and therefore share more similarities with Macedonia than the laws of a dozen U.S. states that have adopted a no-fault system. Whereas Macedonia employs a system of nearly universal health care, such is not the case in the United States. The respective states have adopted either a fault-based system or a no-fault system, but in either case issues of coverage for automobile accidents is more complicated for the lack of a nationalized health care system that at minimum acts as a safety net for treatment of injuries related to automobile accidents. It is posited that complications relating to the lack of universal health care coverage in the United States has led to significantly heightened regulatory intervention by the several states such that the similarities between the free-market approach of the states and of civil law (code) systems are greater than the differences. The paper is not based on empirical data of the legal systems or the medical systems, nor is the undeniable interrelation between a medical system and the corresponding legal system with regard to insurance coverage of primarily health-based issues considered other than to highlight how both may play a part in regulation of the automobile accident insurance industry in light the involvement of public health, safety and welfare.
