Authors: Turusheva A. V. , Kotovskaya Yu. V. , Frolova E. V. 
Published: July 2023

Aim. To assess the impact of frailty syndrome (FS) on the risk of myocardial infarction (MI) and atrial fibrillation (AF) in people aged ≥65 years.Material and methods. A prospective cohort study of a random sample of a free-living population aged ≥65 years (n=611). Measurement of blood pressure, analysis of therapy, chronic comorbidities, laboratory tests, comprehensive geriatric assessment were performed.Results. FS is associated with an increased risk of MI and AF at 2,5 years of follow-up (odds ratio (OR), 3,195, 95% confidence interval (CI), 1,129-9,042; OR, 1,609, 95% CI, 1,013-2,555, respectively). Additional risk factors for MI and AF were high levels of C-reactive protein, type 2 diabetes, and blood pressure.Conclusion. FS was one of the risk factors for MI and AF during 2,5-year follow-up. Common pathogenetic mechanisms for FS and cardiovascular disease, such as chronic inflammation and insulin resistance, may explain the increased risk of MI and AF in patients with FS. Hypertension retains significance in increasing the risk of MI in patients with FS, which must be taken into account when prescribing antihypertensive therapy. FS screening can be used to assess the risk of cardio­vascular events in the elderly and senile age.

Published: July 2023

Introduction:
Epidermolysis bullosa (EB) is a group of rare inherited disorders uniquely characterised by skin, and in some instances, mucosal blistering. In the most severe form of the disease, recessive dystrophic EB (RDEB), the blister-inducing split occurs below the lamina densa. Extensive scarring of the oral mucosa results in limited mouth opening, making speech and mastication difficult. At the same time, oral mucosal blisters often lead to patients restricting their diets to soft, and generally cariogenic, foods, and battling with oral hygiene practices. This results in poor plaque control, a high caries burden and complex dental management.
Aims and objectives:
This paper presents a report on two siblings suffering from generalised RDEB affecting the oral cavity and their extensive dental treatment needs.
Design/Methods:
The siblings were referred to the University of Pretoria Oral Health Centre, complaining of painful teeth and oral mucosal discomfort. Their clinical features, dental condition and subsequent management are presented.
Results:
Restricted mouth opening, limited personal plaque control, and diets limited to soft, carbohydrate-rich foods because of oral mucosal discomfort, resulted in extensive dental decay that required multiple extractions.
Conclusions:
The dental and anaesthetic management of patients with RDEB is complex, and due to the friable tissues, requires the most atraumatic care possible. Ideally, patients with this condition need to have early dental intervention where preventive programmes can be implemented to reduce the need for later extensive and complicated dental interventions. Maintenance of the patient’s oral health is essential to ensure adequate nutrition, yet, reducing the consumption of soft cariogenic diets which increased their caries risk.

Introduction. Postoperative angiographic examinations after endovascular treatment of cerebral aneurysms may demonstrate unstable results, both in the form of recurrence formation, and in the form of increased degree of occlusion with initially incomplete occlusion of the aneurysm sac. Cerebral aneurysm recurrences represent an important medical and social problem comparable in terms of hemorrhage risks with nonoperated aneurysms.Aim. To estimate the early and long‑term results of endovascular treatment of patients with cerebral aneurysms ope rated on using different endovascular techniques. Materials and methods. The present study included 167 patients (48 men and 119 women) with 195 cerebral aneurysms aged from 18 to 75 years who were operated on using endovascular techniques at the neurosurgical department No. 3 of the Russian Research Neurosurgical Institute named after Prof. A. L. Polenov from 2013 to 2016. The average age of the patients was 52 ± 12 years, the minimum age was 18 years, and the maximum age was 75 years. The choice of endovascular treatment method in the patients included in the study was based on anatomico‑topographic and morphometric features of aneurysm, as well as taking into account the period of aneurysmal disease course.Results. The study of data of control angiographic examinations after endovascular treatment of patients with cerebral aneurysms showed that in the remote postoperative period the degree of aneurysm occlusion may differ from that initially achieved. The probability of aneurysm recurrence after its isolated occlusion with coils may reach 13.1 % already in 6 months after surgical treatment, 31.7 % after 12 months and 22.3 % after 36 months, averaging 22.5 % (p < 0.05).Conclusion. The personalized approach in choosing optimal surgical tactics for the treatment of patients with cerebral aneurysms allows to achieve stable radical aneurysm occlusion, to decrease the incidence of postoperative complications and aneurysm recurrences in the long‑term postoperative period.

Background. The problem of concomitant pituitary adenomas and intracranial aneurysms is extensively covered in literature. According to various authors, the prevalence of such a combination of lesions is as high as 9 %, most commonly involving hormone‑producing pituitary adenomas and aneurysms of the anterior circulation, up to 69 % of which originate from the carotid artery.Aim. To analyze and demonstrate the treatment of patients with developed internal carotid artery aneurysm (ICA) against the background of successful conservative therapy of prolactinoma. Materials and methods. In this article we review the literature and present two clinical cases of patients with development of internal carotid artery (ICA) aneurysms after successful conservative treatment of prolactinomas.Results. In both of the described cases, ICA aneurysms with intrasellar extension developed after successful conservative treatment of large invasive prolactinomas. In both cases ICA occlusion were performed and in one of them extra‑intracranial bypass surgery was performed as well.Conclusion. The presented clinical cases suggest potential direct destructive effect of tumor tissue on vessel walls. Currently, it seems reasonable to carry out computed tomography angiography in all patients with adenomas invading the cavernous sinus.

Published: July 2023

In this work, we present an analytical model of dynamic power losses for enhancement-mode AlGaN/GaN high-electron-mobility transistor power devices (eGaN HEMTs).
To build this new model, the dynamic on-resistance (Rdson) is first accurately extracted by our ex-traction circuit based on a double-diode isolation (DDI) method for a high operating frequency up to 1 MHz and a large drain voltage up to 600 V, thus the unique problem of an increase in the dynamic Rdson is presented. Then the impact of the current operation mode on the on/off transi-tion time is evaluated by a dual-pulse-current-mode test (DPCT) which including a discontinu-ous conduction mode (DCM) and a continuous conduction mode (CCM), thus the transition time is revised for different current mode. Afterward the discrepancy between the drain current and the real channel current is qualitative investigated by an external shunt capacitance (ESC) meth-od, thus the losses due to device parasitic capacitance are also taken into account. After these improvements, the dynamic model will be more compatible for eGaN HEMTs.
Finally, the dynamic power losses calculated by this model are verified to be in good agreement with experimental results. Based on this model, we propose a superior solution with qua-si-resonant mode (QRM) to achieve lossless switching and accelerate switching speed.

Published: July 2023

AbstractThis pilot study is founded on an exhaustive investigation of representative and well-documented cases (120) of carbonate systems during the Phanerozoic. We investigated the coupling between geodynamic settings and geometry, physiography, and stratigraphic architecture of carbonate platforms. The objective is to identify and quantify the impact of geodynamic controls on carbonate platforms and possible global trends during the Phanerozoic. Carbonate platforms are characterized in terms of geometry, stratigraphic architecture, time duration, preservation rate, progradation and rates of progradation, platform type, and thickness. Geodynamic parameters are characterized in terms of basin physiography, basement depth and type, tectonic setting, and subsidence origin. Relationships between carbonate parameters and geodynamic characteristics are investigated, leading to nine models of Geodynamic Carbonate Platforms. Passive margin is the most favorable geodynamic setting for the development of carbonate platforms in three dimensions. The continental crust hosts most of the carbonate platforms independently of time and geodynamic settings. Carbonate platforms developed above the exhumed mantle or oceanic crust (volcano) are the exception or very small and isolated. Global trends during the Phanerozoic of carbonate platform lateral extend, progradation, or thickness are tentatively interpreted in relation to geodynamic and eustatic parameters. The concept of spatial intersection between geodynamic and climatic windows favorable to carbonate platforms is introduced with its possible retroaction to the global carbon cycle.
A paradigm change: Focused Electron Beam Nanostructuring of Glass
Authors: Hofmann Martin , Weigel Christoph , Strehle Steffen , Holz Mathias 
Published: July 2023

Abstract

We demonstrate a paradigm change in nanofabrication by using a focused electron beam in an operating mode as used in conventional scanning electron microscopy, previously known as non-destructive technique, for direct and large-scale glass and glass ceramics patterning. Nanostructured glasses and glass ceramics are of fundamental importance for many applications ranging from optics to nano- and microscale devices over precision engineering and metrology. Direct focused electron beam patterning can hereby replace the elaborate combination of surface masking combined with dry-chemical reactive ion etching and enable new and efficient fabrication strategies for the creation of structures being several hundred nanometers deep. We discuss a first model based on ion migration and successfully realized the structuring process using electron energies of 5 to 15 keV in combination with different kinds of glasses, such as fused silica and ultra-low expansion glass. We furthermore demonstrate that this technique can be realized in literally any conventional scanning electron microscope, which thus enables a comparatively simple implementation in support of a broad field of applications. By controlling the surface beam trajectory, freeform surface structures and structure arrays can be directly engraved into the glass surface, which includes furthermore fragile and suspended structures and the embedding of metal structures. The technique is also compatible with 3D surface structures as long as they can be accessed by the electron beam.

Abstract

Terrestrial ecosystems are significant carbon sinks and are crucial for understanding the regional and global carbon cycles, energy flow, and climate change. As land use change is a significant factor affecting ecosystem carbon stocks, studying it is essential to comprehending the evolution of regional carbon sink functions and achieving sustainable development goals. The drastically diverse land use patterns in each of the study area's functional areas resulted in significant differences in carbon stocks between them. This study explores the evolution traits of carbon stocks based on land use data and their driving mechanisms in Chongqing during the past 30 years by using spatial analysis, the InVEST model, and geographic probes. The results demonstrate the significant change in land use change in the study area, which led to a 5.1078Tg decrease in total carbon stock, a decline of 1.5%. The main pathway for carbon loss pathway in the evolution of carbon stock is the conversion of cropland to construction land, and the primary carbon compensation pathway is the conversion of grassland and cropland to forest land, with a spatial distribution characterized by "higher in the whole area and obvious local differences". The degree of land use contributes most to the evolution of carbon stocks. Moreover, the interaction of pairwise factors played a more important role in affecting the evolution of carbon stocks than did each factor individually. The case study in this paper shows that land use change is a significant driving mechanism for the evolution of carbon stock, and the development of a driving model theory is appropriate for deciphering the trajectory of carbon stock evolution and offering research suggestions for other regions.
The influence of mounting place of FBG sensor in composite on the base of FEM simulation.
Authors: Tafese Iyasu Tafese 
Published: July 2023

Abstract
In composite materials, a real-time strain development can be measured by mounting a small-diameter fiber Bragg grating (FBG) sensors in structures. The mounting position of FBG sensors determines the accuracy in capturing and monitoring the mechanical behavior of composites. In this study, the influence of mounting place of FBG sensors on mechanical response of composite structures was investigated using Finite Element Method (FEM). The FEM model incorporates the composite material properties, such as fiber orientation and resin matrix. A parametric study is conducted by varying the mounting locations of FBG sensors within the composite laminate. In this study strain variation with respect to distance between FBG sensor and glass stiffener was investigated. The findings of this study provide valuable insights into the optimal mounting positions of FBG sensors within composite structures for reliable strain monitoring and damage detection. This knowledge can aid engineers and researchers in designing efficient and robust structural health monitoring systems, leading to enhanced safety, durability, and performance of composite materials in various applications, including aerospace, automotive, and civil engineering.

Published: July 2023

Abstract

Background
Diabetes Mellitus is the second leading cause of death in South Africa and almost 90 000 people died from diabetes-related causes in the year 2019. The purpose of this study was to investigate facilitators that can be harnessed to strengthen community actions and barriers that should be redressed in structured public health and health promotion programs for people living with diabetes mellitus at a primary health care level.
Methods
Using face to face qualitative approach, an exploratory design was conducted. The Ottawa Charter was adopted as a model to guide health promotion strengthening actions for people living with diabetes mellitus. This study was conducted at Ngangelizwe Community Health Centre. Ngangelizwe is one of the townships located about 2 km east of Mthatha Town in the Eastern Cape Province of South Africa. Conveniently, 20 participants living with diabetes mellitus were selected to participate voluntarily in the study. Thematic analysis method with the assistance of Atlas ti version 9.0 software was used to analyse the data and presented under two broad themes.
Results
Five overarching themes were yielded and categorized as facilitators and barriers. Facilitators included enhancing the role of community healthcare workers, strengthening of health education activities. Barriers encompassed lack of support groups, lack of food security, and unavailability of community health promotion programs.
Conclusion
The study concluded with recommendation of designing health promotion program for primary health care prevention of diabetes mellitus at a community level. Engagement of collaborative intervention of relevant key stakeholders working together as a primary health care team, health promotion practitioners and community health care workers is recommended. The public health care team should be motivated to reach out into households and communities to empower people to have control over diabetes and improve their health.
Bridge damage identification with improved HHT and PSD sensitivity method based on vehicle response
Authors: FANG YouLiang , Xing Jie , Zhang Ying 
Published: July 2023

Abstract
A damage identification method combining improved Hilbert-Huang transform (HHT) and power spectrum density (PSD) sensitivity analysis is proposed to study the acceleration response signals of a test vehicle and to identify damage in bridge structures. This study uses a single acceleration sensor arranged on the test vehicle to identify single and multiple positions of damage on the bridge and identify the degree of damage. Firstly, the vehicle acceleration response is transformed by HHT to determine the position of damage on the bridge structure using changes in the 3D time-frequency amplitude spectrum, which shows a decrease in the instantaneous frequency and an increase in the instantaneous amplitude at the damage position. Secondly, after determining the damage position on the bridge structure, the PSD sensitivity method is used to identify the damage parameters and determine the damage degree at the damage position. The combination of the two methods solves the problem that the traditional direct use of signal processing technology (such as wavelet transform, Hilbert transform) can only identify the damage location of the bridge and use the power spectrum sensitivity to identify the damage degree of each unit of the structure, which leads to a large amount of sensitivity calculation .The identification capabilities of the proposed technique are studied varying the damage locations, crack depths and velocity of vehicle speed vehicle mass .The effect of ambient noise is also taken into account. Numerical simulations shows that the method presented in this paper could identify damage in bridge structures.
