Nonintegrable dynamical systems have complex structures in their phase space.Motion of a test charged particle in a dipole magnetic field can be reduced to a 2degree-of-freedom (2 d.o.f.) nonintegrable Hamiltonian system. We carried out asystematicstudyoforbitsofchargedparticleswithanazimuthalinitialvelocityina dipole field via calculation of their Lyapunov characteristic exponents (LCEs)and escape times for a dimensionless energy less and greater than 1/32, respec-tively. Meridian plane periodic orbits symmetric with respect to the equatorialplane are then identified. We found that 1) symmetric periodic orbits can be clas-sified into several classes based on their number of crossing points on the equato-rialplane;2)theinitialconditionsoftheseclasseslocateonclosedloopsorclosedcurves going through the origin; 3) most isolated regions of stable quasi-periodicorbits are associated asymmetric stable periodic orbits; 4) classes of asymmet-ric periodic orbits either go through the origin or terminate at flat equatorialplane orbits with the other end approaching centers of spiral structures; 5) thereare apparent self-similarities in the above features with the decrease of energy.

Authors: Jing Zhiyi , Wu Ying , Xu Yeyin
Published: March 2023

Epilepsy is a highly prevalent neurological disorder worldwide, and the automatic detection of epileptic activity in clinical practice is a significant focus of researchers. In this study, we construct a high-performance model for normal and epileptic electroencephalogram signals using a con-volutional neural network architecture called Shallow ConvNet based on the CHB-MIT dataset. The model achieves a maximum classification accuracy of 98%. We also investigate the effects of different data slice and sample sizes on the model performance. Results show that larger data slice sizes can improve accuracy and generalization ability to a certain extent, while increasing the sample size of the training set only improves accuracy but not generalization ability. The best overall performance is achieved by the classifier trained with a slice size of 5 seconds and a training set sample size of 500. These findings provide theoretical guidance for the clinical application of automatic epilepsy detection.

Published: March 2023

Objective
Our study aimed to analyze the main pathogenic characteristics of Hand, Foot and Mouth Disease (HFMD) in Jiaxing City in 2022 and analyze enterovirus (EV)-positive samples that could not be typed by gene sequencing to provide insights for further prevention and control of HFMD.
Methods
Nucleic acid sequencing of enteroviruses was performed on 585 clinical samples from Jiaxing City in 2022, and Nucleic acid sequencing and molecular characterization of the VP1 region were performed on 30 strains of EV-positive samples.
Results
Among the 585 clinical samples, CV-A6, CV-A16, and CV-A10 samples were 51.6%, 15.6%, and 12.1%, respectively, while EV-positive but unsuccessfully typed samples were 13.3%. Sequence analysis revealed that 12 strains of CV-A4, 2 strains of CV-B3, 6 strains of CV-A6, and 2 strains of E-18 were successfully identified in the 30 strains of EV-positive samples. CV-A4 was found to be the most abundant strain.
Conclusion
The prevalence of HFMD in Jiaxing City in 2022 was dominated by CV-A6, supplemented with CV-A16, CV-A10, and other enteric strains. CV-A4 was the most abundant strain among the untyped EV-positive samples, and its prevalence needs to be closely monitored.

Published: March 2023

Purpose Radiotherapy is essential to cancer treatment, while it inevitably injures the surrounding normal tissues, and bone tissue is one of the most common sites prone to irradiation. Bone marrow mesenchymal stem cells (BMMSCs) are sensitive to irradiation and the irradiated dysfunction of BMMSCs may be closely related to irradiation-induced bone damage. Macropahges paly important role in stem cell function regulation, bone metabolic balance and irradiation response, but the effects of macrophages on irradiated BMMSCs are still unclear. This study aimed to investigate the role of macrophages and macrophage-derived exosomes in restoring irradiated BMMSCs function.
Methods The effects of macrophage conditioned medium (CM) and macrophage-derived exosomes on osteogenic and fibrogenic differentiation capacities of irradiated BMMSCs were detected. The key microribonucleic acids (miRNAs) and targeted proteins in macrophage-derived exosomes were also determined.
Results The results showed that X-ray irradiation significantly inhibited the proliferation of BMMSCs. Additionally, it caused a differentiation imbalance of BMMSCs, with decreased osteogenic differentiation and increased fibrogenic differentiation. M2 macrophage-derived exosomes (M2D-exos) inhibited the fibrogenic differentiation and promoted the osteogenic differentiation of irradiated BMMSCs. We identified that miR-142-3p was significantly overexpressed in M2D-exos and irradiated BMMSCs treated with M2D-exos. After inhibition of miR-142-3p in M2 macrophage, the effects of M2D-exos on irradiated BMMSCs differentiation were eliminated. Furthermore, transforming growth factor beta 1 (TGF-β1), as a direct target of miR-142-3p, was significantly decreased in irradiated BMMSCs treated by M2D-exos.
Conclusion This study indicated that M2D-exos could carry miR-142-3p to restore the differentiation balance of irradiated BMMSCs by targeting TGF-β1. These findings pave the way for a new, promising, and cell-free therapeutic method to treat radiation-induced bone damage.

Published: March 2023

Background
The frequency of metastasis to the pancreas is very low, and the frequency of metastasis from squamous cell carcinoma of the esophagus is even lower. Although curative resection of these metastatic lesions has been reported for some patients, the survival benefit of these procedures has not yet been clearly determined.
Case presentation
The patient was a 54-year-old man who was found to have lower thoracic esophageal cancer. Computed tomography showed a 2-cm tumor in the tail of his pancreas. Since no other obvious distal metastases were observed, the patient underwent simultaneous surgical procedures that excised both the esophageal squamous cell carcinoma and the pancreatic metastasis. Histopathologic examination confirmed squamous cell carcinoma in both specimens. The patient has been free of disease for 9 months since the resection. A literature review of all relevant cases to date found that the site of the primaries of all cases of esophageal cancers with metastasis to the pancreas was the lower thoracic esophagus.
Conclusion
Complete simultaneous resections of esophageal squamous cell carcinoma and a solitary metastasis to the pancreas is beneficial and may produce good outcomes. However, because of the low number of such reports, further studies are needed to confirm the benefits of surgery.

Authors: Zhang Piao , Xu Feng , Hu Ziyun , Liang Dandan , Liang Shaoshan , Zhu Xiaodong , Yang Fan , Zeng Caihong
Published: March 2023

Background
Membranous nephropathy (MN) is an immune complex mediated disease. The loss of massive proteinuria can lead to Fanconi syndrome, clinically, manifesting as renal glycosuria. The prevalence and prognosis of M type phospholipase A2 receptor (PLA2R)-related MN with renal glycosuria remain unknown.
Methods
Patients diagnosed as PLA2R-related MN with renal glycosuria were reviewed, and the control group comprised of patients with MN without renal glycosuria who were randomly selected in a ratio of 1:3.
Results
From January 2015 to January 2020, a total of 50 patients identified as PLA2R-related MN with renal glycosuria were included, with a prevalence of 2.3%. Compared with patients without renal glycosuria, those with renal glycosuria exhibited greater proteinuria, lower estimated glomerular filtration rate (eGFR), as well as higher use of diuretics, anticoagulants, antibiotics, traditional Chinese medicine and tacrolimus within 3 months prior to renal biopsy (all p < 0.05). Histologically, patients with renal glycosuria exhibited more severe degrees in pathological stages, acute/chronic tubulointerstitial lesions and tubulointerstitial inflammation (all p < 0.05). Of the 10 cases treated with rituximab (RTX), 6 (60%) maintained proteinuria remission, and 5/6 (83.3%) achieved urine glucose remission. Multivariate Cox regression analysis showed that renal glycosuria and age > 50 years were independent risk factors for end-stage renal disease (ESRD) or 30% reduction of eGFR in patients with PLA2R-related MN.
Conclusion
PLA2R-related MN patients with renal glycosuria presented with more severe clinicopathological manifestations and worse prognosis. Suspected nephrotoxic drugs should be used rationally, and RTX could be used as a treatment option.

Published: March 2023

Objective
Catheter-associated urinary tract infections (CAUTI) are common worldwide, but due to limited resources, its actual burden in low-income countries is unknown. Currently, there are gaps in knowledge about CAUTI due to lack of surveillance activities in Sierra Leone. In this prospective cohort study, we aimed to determine the incidence of CAUTI and associated antibiotic resistance in two tertiary hospitals in different regions of Sierra Leone.
Results
The mean age of the 459 recruited patients was 48.8 years. The majority were females (236, 51.3%). Amongst the 196 (42.6%) catheterized patients, 29 (14.8%) developed CAUTI. Bacterial growth was reported in 32 (84%) patients. Escherichia coli (14, 23.7%), Klebsiella pneumoniae (10, 17.0%), and Klebsiella oxytoca (8, 13.6%) were the most common isolates. Most isolates were ESBL-producing Enterobacteriaceae (33, 56%) and WHO Priority 1 (Critical) pathogens (38, 71%). Resistance of K. pneumoniae, K. oxytoca, E. coli, and Proteus mirabilis was higher with the third-generation cephalosporins and penicillins but lower with carbapenems, piperacillin-tazobactam and amikacin. To reduce the high incidence of CAUTI and multi-drug resistance organisms, urgent action is needed to strengthen the microbiology diagnostic services, integrate multi-drug resistance organism surveillance into the routine clinical services and establish functional antibiotic stewardship programs in these hospitals.

Authors: Waluyo Jati Kuat , Agustina Linda , Deviani  , Gusti Ketut Agung Ulupui I , Kismayanti Respati Dwi
Published: March 2023

Sustainability reporting reflects business contribution to sustainable development. Indonesia seeks to engage in sustainable development by assessing the companies using the PROPER scale. The study aims to determine whether environmental performance (assessed by the PROPER scale) affect sustainability reporting of companies in Indonesia. The research population includes companies listed on the Indonesia Stock Exchange that have published annual and sustainability reports within five consecutive years. This study employs WarpPLS to analyze data from 85 observations. The results show an increase in the disclosure of sustainability reports when the audit committee and the board of directors hold regular meetings. Companies without governance committees focus more on improving governance rather than disclosing sustainability reports. Environmental performance, when associated with the type of industry and governance committee, will increase sustainability reporting. However, a company with good environmental performance will make the audit committee and directors focus on other responsibilities because the community already understands that a company with a good PROPER rating properly manages its environmental impact and is aware of the importance of sustainable development. This study concludes that environmental performance measured by the PROPER scale positively affects sustainability reporting considering the type of industry, governance committee, audit committee, and board of directors of companies in Indonesia. The Indonesian government must support, facilitate, and encourage companies to achieve the gold category in the PROPER scale and promote higher disclosure of sustainability reports to contribute to sustainable development.

Published: March 2023

Developing countries are characterized by a low level of tax compliance arising from weaknesses in tax administration and trust deficits. This poses a critical challenge toward the attainment of developmental goals. This paper aims to examine the moderating role of trust in tax authorities for the relationship between tax administration and personal income tax compliance in Nigeria. The study used a survey design to obtain data through a structured questionnaire administered to randomly selected individual taxpayers from Nigeria; 365 responses were collected. The OLS results revealed that tax administration significantly influences personal income tax compliance (β = 0.301, t = 4.068, and p-value = 0.000). Trust in tax authorities significantly influences personal income tax compliance (β = 0.183, t-value = 3.650, and p-value = 0.000). Furthermore, the result showed that trust in tax authorities positively moderates the relationship between tax administration and personal income tax compliance (β = 0.323, t = 4.098, and p-value = 0.000). This study concludes that tax administration significantly affects personal income tax compliance, and trust in tax authorities moderates this relationship in Nigeria.

Authors: Kalashnikova Anna , Makaganchuk Sofiya
Published: March 2023

The article features the image of the President of the Russian Federation in current political Internet jokes and the way his image is compared with other political and public figures. Internet joke is a hybrid genre of modern communication; it can be political, virtual, mundane, etc. The study involved general scientific methods of analysis, synthesis, and interpretation, as well as special linguistic methods of discourse and content analyses. The most frequent characters in jokes about V. V. Putin appeared to be D. A. Medvedev, D. S. Peskov, R. A. Kadyrov, D. Biden, B. Obama, D. Trump, etc. The image of V. V. Putin is dominated by his influence, authority, strength, and leadership in the Russian and international political arena. By comparing V. V. Putin with other political figures, jokes ironically reduce his image or that of his political associates and opponents. They also represent popular ideas about the unique character of presidential status in Russia.

Chances and barriers of building information modelling in wastewater management
Authors: Kretschmer Florian , Franziskowski S. , Huber F. , Ertl T.
Published: March 2023

The advancing digitalisation is one of the great challenges of our times. Related activities also concern the wastewater sector. In the field of building construction, one emerging approach is building information modelling (BIM). The presented work investigates to which extent BIM practices have already found their way to wastewater management, and what kind of benefits and constraints are incorporated. Information is collected by means of a literature review and international expert surveys. Results indicate that several BIM-related key elements are already well established in the sector, but not necessarily in the intended manner. Consequently, the digital transition in the wastewater sector is not about replacing existing procedures and techniques but to rethink and optimise them. This primarily concerns data and information management in combination with the application of digital tools. Furthermore, wastewater management requires more integrated approaches, involving interdisciplinary/collaborative concepts and life cycle perspectives. Appropriate change management is necessary to give support and guidance to employees during the transition process. Furthermore, also from the political side, a clear definition and communication of the pursued digital vision is important. This article aims at stimulating discussion and research to optimise wastewater management from the digital perspective.

The paper analyses the representation of the mother figure in thirteen short stories by Lygia Fagundes Telles, published between 1949 and 2007. Proving her status as a major figure in contemporary Brazilian literature, Lygia poses the question from multiple perspectives, also using a wide diversity of styles and tones. In some of the narratives, more or less common and reasonably peaceful situations are enacted, but there are others that could illustrate a psychiatry or psychoanalysis manual. The set, by the way, provides material that could serve as a basis for a history of contemporary women

Published: March 2023

The aim of this article is to study Bishop of Porto D. Hugo, a key figure to understand the transformation of Portugal in the 12th century. Probably ailing from France, he was archdeacon in Compostela under Diego Gelmírez and consecrated bishop by Maurice of Braga. D. Hugo dealt with the most important problems of his time: the conflict between the See of Compostela and Braga, the political evolution of the County of Portugal and the relations with the Papacy. The study of D. Hugo reveals a very peculiar image of a medieval bishop: clergyman, politician, writer and tireless traveller.

Published: March 2023

Sugarcane streak mosaic virus (ScSMV) is the most important viral disease of sugarcane in Indonesia with distribution in almost all commercial sugarcane plantations. The disease causes significant yield losses of both cane tonnage and sugar yield. The use of resistant varieties is the best approach for controlling viral diseases. This study aims to investigate resistance response of several introduced varieties against ScSMV in a glasshouse condition and the impact of the viral infection on chlorophyll and proline content in sugarcane leaves.  Sugarcane plants were inoculated using ScSMV inoculum one month after planting using an abrasive pad rubbing method. Disease incidence and severity was observed at week 4-12 after inoculation and variety resistance levels were classified based on disease incidence. Confirmation of the virus was done by RT-PCR. Spectrophotometer was used to measure chlorophyll content at dual wavelengths of 645 and 663 nm, and proline content at wavelengths of 520 nm. The results showed that most of the tested varieties were susceptible to ScSMV. There are six highly resistant varieties, namely SRA 1, SRA 2, N 10-4, N 10-7, N10-9, and N 10-13, but these varieties still require to be tested on a field scale. ScSMV infection generally decrease chlorophyll and proline content. However, the physiological effect of ScSMV infection on chlorophyll and proline content needs further investigation.
History of Leadership through Education and Innovation in the Ambulance Service in Britain
Authors: Slater Dr Alan
Published: March 2023

Purpose: This paper tracks the hitherto poorly documented history of the ambulance service in Britain from early military history to the present day identifying the leaders who motivated change and through education and innovation provided significant developments in pre-hospital patient care. Methodology: Desk research and interpretation of social and medical issues raised.Findings: The ambulance service developed from an early military need through a period when monks offered care to the local population. Followed by philanthropists and local doctors adapting and funding practices developed elsewhere, to independent hospitals run by doctors offering inbound transport. Subsequently, political pressure forced local authorities to offer pre-hospital care and transportation to hospitals for the sick and injured. The war years saw a military concentration on pre-hospital care followed by the integration of the ambulance service into the newly formed National Health Service (NHS). The profession of the paramedic was formed, technical innovation in communication, transportation, and on-scene patient care encouraged standardization of service. The ambulance service is an integral part of the NHS providing essential pre-hospital medical care.Originality: A description of the social history of the ambulance service in Britain defining the context, role of education in the motivation for leadership and innovation.
Transformar los sentidos y el sentir. El activismo cultural de las redes de acompañantes de abortos en América Latina
Authors: Vacarezza Nayla Luz , Burton Julia
Published: March 2023

Este artículo examina el activismo cultural de la Red Feminista Latinoamericana y Caribeña de Acompañantes de Aborto. Aunque las estrategias culturales son cruciales para el activismo por el aborto libre y seguro, los estudios se han focalizado mayormente en sus aspec- tos legales y sanitarios. Por eso, analizamos una serie de producciones culturales en las que el activismo intenta transformar las maneras en que el aborto es representado y sentido. Nuestros hallazgos indican que estas producciones asocian el aborto con la dignidad, la autonomía y el poder para decir “no” a la maternidad forzada. Aunque los relatos muestran que el aborto en contextos de ilegalidad puede producir miedo, dolor y angustia, también lo asocian con el alivio, la solidaridad entre mujeres y el amor propio. Por último, analizamos la emergencia de políticas interseccionales que conectan la ilegalidad y la inseguridad del aborto con regímenes de explotación colonial, racista y capitalista.

Byzantine heritage in contemporary Turkey: Research features and political significance
Authors: Belokonev S. Yu. , Ivanov V. G. , Levina E. V.
Published: March 2023

The article considers the politics of memory of the Turkish government in relation to the Byzantine heritage in the country and the reaction of the states whose historical narrative and identity are associated with the Byzantine Empire’s legacy. The article is based on a wide range of sources in Turkish, Greek, English and Russian. The authors believe that the Turkish policy of Islamization and the ideology of neo-Ottomanism, which are implemented by the ruling AK Party under the leadership of the President R.T. Erdogan, lead to the gradual dismantling of the remaining Byzantine heritage, which was proved by the transformation of the Monastery of the Choir and the Hagia Sophia into mosques. Turkish society, except for a few dissidents many of whom have already left the country, does not show interest in the history of Byzantium and perceives the policy of the ruling party quite pragmatically, according to the opinion polls. The international reaction to the decisions of the Turkish leadership was quite restrained and in general did not focus on Byzantium and its role in history. Thus, European politicians and researchers criticized mainly the anti-Western idea of Erdogan’s actions and rhetoric, while Greece fears mostly the revival of Ottoman imperialism and considers the Byzantine legacy as a part of Hellenism. The authors conclude that it was Russian society that defined the policy of Erdogan as the destruction of the Byzantine heritage of the Eastern Orthodox civilization (primarily due to the position of the Russian Orthodox Church), which made the Russian political leadership discuss this issue at the highest level. Moreover, in the international dimension, Ankara’s consistent policy to dismantle the Byzantine heritage affects the image and ideology of the Russian state to a greater extent than that of Greece, which is determined by the sustainable perception of Russia as the successor of the Byzantine tradition.
PERFORMANCE ANALYSIS OF A QUASI-Z-SOURCE CONVERTER FOR SOLAR PHOTO VOLTAIC SYSTEM POWERED WATER PUMPING SYSTEM
Authors: S Jeyanthi , V Manikandan B
Published: March 2023

Solar Photo Voltaic system (SPVS)-based water pumping has been gaining
wonder attention because it serves as an effective alternative to
traditional energy sources in remote areas. In this paper, an SPV panel
is connected to pumping applications through back-to-back converter
arrangements. This proposed work three different DC/DC boost converter
comprises a conventional boost converter (BC), Z-source boost converter
(ZSC) and Quasi Z-Source Boost Converter (QZSC) at the front-end for dc
integration of SPVS and a three-phase voltage source inverter (VSI) at
the back-end, and it fed a Brushless DC Motor (BLDC) motor is connected.
The dc link capacitor is connected in between the converter and inverter
system. The front-end converter is employed to regulate the dc voltage
obtained from the SPVS and the maximum power is extracted by adopting
two different algorithms of Incremental Conductance Maximum Power Point
Tracking (INC-MPPT) technique and INC trained artificial neural network
(INC-ANN-MPPT). The back end two controller proposed to operation of VSI
such as conventional MPP DC link voltage (V )
reference and closed loop speed dual tuned PID (VSDT-PID). The
conventional control trained ANN controller (VSDT -ANN) with hall effect
feedback to optimal operation of motor speed. The back-end converter is
employed to regulate the speed of the water flow by controlling the
speed of the BLDC motor, irrespective of the irradiance level of SPV. By
altering the dc link voltage, the BLDC motor’s different configuration
PV insolation and motor load torque. To analysis different configuration
conversion system power extraction, transient, settling time, voltage,
current and speed deviation of the proposed conversion system, and then
compared with the implemented conversion system in MATLAB/ Simulink

The differences in the functional diversity and species diversity of
macroinvertebrates can be based to evaluate the changes in local
environment. However, there are little available analysis on the effect
mechanism of seasons on the functional characteristics of
macroinvertebrate communities in the subtropical region. This work
compared the functional feeding groups (FFG) of macroinvertebrates in
wet season, normal season, and dry season of 2021 in Jingui River in
Shenzhen. This work mainly was aimed to comprehend the connection
between the environmental driving elements in the Jingui River and the
seasonal distribution of the FFG of macroinvertebrates. The highest
species diversity and abundance were found among the collector-gatherers
(GC), while the largest biomass was observed among the predators.
Overall, the functional diversity of the Jingui River exhibited a
significantly seasonal change. In particular, the functional diversity
decreased in wet season, implying a stronger disturbance. A multiple
regression analysis revealed that the species diversity and stream
environmental parameters might account for 12.8% - 72.9% of the
functional diversity of macroinvertebrates.
Local weather affects body condition of three North American songbird species on the Texas coast
Authors: McCloy Michael , Glasscock Selma , Grace Jacquelyn K.
Published: March 2023

Body condition is a frequently used physiological indicator of avian
health and is affected by an array of environmental variables. Although
a number of studies have investigated the specific effects of individual
weather variables on body condition in birds, few have analyzed the
effects of both temperature and precipitation within the context of an
extreme weather event such as hurricanes. In this study we examined the
relationship between breeding season body condition and daily maximum
temperature, daily minimum temperature, and monthly total precipitation
for three passerine bird species at the Welder Wildlife Refuge near
Rockport, Texas. We also evaluated yearly changes in body condition over
a twelve-year period for northern cardinals (Cardinalis cardinalis),
painted buntings (Passerina ciris), and white-eyed vireos (Vireo
griseus), focusing on the extreme precipitation event of Hurricane
Harvey which caused heavy localized flooding. We found that body
condition declined with average daily minimum and maximum temperatures,
while precipitation had varied, species-specific effects in the three
species analyzed. Our results also suggest that northern cardinals
experienced a notable reduction in average body condition in the two
years following Hurricane Harvey. Taken together, we conclude that
short-term precipitation and temperature drivers can be important
correlates of body condition in songbirds and that severe weather events
may reduce body condition in some bird species.

Over 645 million people worldwide have been infected with SARS-CoV-2,
the virus that causes COVID-19. Critical knowledge gaps regarding the
characteristics, duration, and impact of symptoms due to “long COVID”.
This study evaluated the persistence of symptoms at one year following
hospitalization with COVID-19, comparing responses on standardized
measurement tools to population norms. Adults hospitalized with COVID-19
March-October 2020 during the initial emergence period in Southeast
Michigan were eligible. A detailed survey was conducted via telephone
9-15 months after hospital discharge. Questions assessed fatigue,
dyspnea, and physical functioning related to their COVID-19 illness. The
median World Health Organization Disability Assessment Schedule (WHODAS)
polytomous score placed 50% (n=20/40) of participants in the 90
percentile of disability based on population norms.
The mean SF-36 physical functioning score was almost nine points below
population norms (mean=70.6, standard deviation=27.4). Additionally,
47.5% of individuals (n=19) were severely emotionally affected by their
health condition. Over half of participants surveyed were still impacted
a year after initial infection, experiencing limited functional ability,
fatigue, and emotional difficulties. Given the impact of these symptoms
on day-to-day quality of life, further studies are needed to develop
strategies for treatment and management of post-COVID conditions.
