Theoretical aspects of obtaining a helical surface from a thin strip during sheet stamping
Authors: Скрябин М.Л. 
Published: September 2021

В статье рассмотрены теоретические аспекты получения винтовой поверхности из тонкой полосы при листовой штамповке. Также предложена модель для расчета компонентов напряженно-деформированного состояния полосы и отдельных технологических параметров. Для удобства расчетов предполагается, что полоса имеет достаточную длину и угол закручивания по всей длине полосы одинаков. Несмотря на значительные упрощения геометрического характера, задача о кручении полосы остается сложной, вследствие двумерности напряженного состояния, геометрической и физической нелинейности процесса деформирования. Ее дальнейшее решение целесообразно основывать на методе конечных элементов, ориентируясь на применение ЭВМ. Для замыкания системы уравнений, описывающих поведение дискретной модели полосы на шаге нагружения, необходимо связать напряжения и малые приращения деформаций в середине каждого элемента. Для этого используем теорию пластического течения, пренебрегая упругими составляющими деформаций вследствие их малости по сравнению с большими пластическими деформациями.
The article deals with the theoretical aspects of obtaining a helical surface from a thin strip during sheet stamping. A model is also proposed for calculating the components of the stress-strain state of the strip and individual technological parameters. For convenience of calculations, it is assumed that the strip has a sufficient length and the angle of twisting along the entire length of the strip is the same. Despite significant geometric simplifications, the problem of band torsion remains complex due to the two-dimensionality of the stress state, the geometric and physical nonlinearity of the deformation process. Its further solution should be based on the finite element method, focusing on the use of computers. To close the system of equations describing the behavior of the discrete band model at the loading step, it is necessary to relate the stresses and small increments of deformations in the middle of each element. To do this, we use the theory of plastic flow, neglecting the elastic components of deformations due to their smallness in comparison with large plastic deformations.

Произведена оценка влияния флуктуационных стационарных мультипликативных помех, действующих одновременного с аддитивными помехами, на точность измерения неэнергетических параметров информационных сигналов. Показано, что мультипликативная помеха низкого уровня оказывает более сильное влияние на точность измерения времени прихода, чем на точность измерения частоты полезного сигнала. Осуществлена количественная оценка влияния мультипликативной помехи на точность измерения неэнергетических параметров полезного сигнала.
The influence of fluctuating stationary multiplicative interference acting simultaneously with additive interference on the accuracy of measurement of non-energy parameters of information signals is estimated. It is shown that low-level multiplicative interference has a stronger effect on the accuracy of the arrival time measurement than on the accuracy of the useful signal frequency measurement. A quantitative assessment of the effect of multiplicative interference on the accuracy of measurement of non-energy parameters of the useful signal is carried out.

Failure propagation in interdependent multi-level networks
Authors: Брусков А.А. 
Published: September 2021

В этой работе разрабатываются новый подход и алгоритмические инструменты для моделирования и анализа живучести сетей с разнородными узлами, а также рассматривается их применение в космических сетях. Космические сети позволяют совместно использовать ресурсы космических аппаратов на орбите, такие как хранение, обработка и обмен данными. Каждый космический аппарат в сети может иметь различный состав и функциональность подсистем, что приводит к неоднородности узлов. Большинство традиционных анализов живучести сетей предполагают однородность узлов и в результате не подходят для анализа космических сетей. Эта работа предполагает, что гетерогенные сети могут быть смоделированы как взаимозависимые многоуровневые сети, что позволяет проводить анализ их живучести. Многоуровневый аспект фиксирует разбивку сети в соответствии с общими функциональными возможностями в различных узлах и позволяет создавать однородные подсети, в то время как аспект взаимозависимости ограничивает сеть для захвата физических характеристик каждого узла.
In this paper, we develop a new approach and algorithmic tools for modeling and analyzing the survivability of networks with heterogeneous nodes, and also consider their application in space networks. Space networks allow the sharing of spacecraft resources in orbit, such as data storage, processing, and exchange. Each spacecraft in the network may have a different composition and functionality of subsystems, which leads to heterogeneity of nodes. Most traditional network survivability analyses assume node homogeneity and as a result are not suitable for space network analysis. This work suggests that heterogeneous networks can be modeled as interdependent multi-level networks, allowing analysis of their survivability. The multi-level aspect captures the network breakdown according to the common functionality in different nodes and allows for the creation of homogeneous subnets, while the interdependence aspect restricts the network to capture the physical characteristics of each node.

Abstract
Photocatalysis has been regarded as a kind of environmentally friendly advanced oxidation process to eliminate pollutants. In this work, Phosphorus-doped carbon nitride tube (PCN) was synthesized via a hydrothermal calcination method and applied to degrade tetracycline (TC) through combing with peroxydisulfate (PDS) under visible light irradiation. Experimental results showed that the optimized catalysts PCN-5 exhibited superior degradation performance and reusability for TC degradation. 96.4% TC could be degraded for optimal PCN-5 with 0.3 g·L−1 catalysts and 1.0 g·L−1 PDS under visible light within 60 min. In addition, the degradation rate constant for TC of PCN + PDS + Vis system was still above 85% after five uses. Radical trapping experiment indicating that O2·− is the dominant radical for TC degradation. The findings of this work revealed the potential application of the PCN + PDS + Vis system toward degrading contaminants in wastewater.
New Insights into Neuropeptides Regulation of the Immune System and Hemopoiesis: Effects on Hematologic Malignancies
Authors: Allegra Alessandro , Sant’Antonio Emanuela , Musolino Caterina , Ettari Roberta 
Published: September 2021

:Several neurotransmitters and neuropeptides were reported to join to or to cooperate with different cells of the immune system, bone marrow, and peripheral cells and numerous data support that neuroactive molecules might control immune system activity and hemopoiesis operating on lymphoid organs, and the primary hematopoietic unit, the hematopoietic niche. Furthermore, many compounds seem to be able to take part to the leukemogenesis and lymphomagenesis process, and in the onset of multiple myeloma. In this review, we will assess the possibility that neurotransmitters and neuropeptides may have a role in the onset of haematological neoplasms, may affect the response to treatment or may represent a useful starting point for a new therapeutic approach. More in vivo investigations are needed to evaluate neuropeptide’s role in haematological malignancies and the possible utilization as an antitumor therapeutic target. Comprehending the effect of the pharmacological administration of neuropeptide modulators on hematologic malignancies opens up new possibilities in curing clonal hematologic diseases to achieve more satisfactory outcomes.
Effects of Alpha-lipoic Acid Supplementation on Human Diabetic Nephropathy:
A Systematic Review and Meta-analysis
Authors: Vakali Elena , Rigopoulos Dimitrios , Carrillo Andres E. , Flouris Andreas D. , Dinas Petros C. 
Published: September 2021

Background:
Diabetic nephropathy (DN) is kidney dysfunction, which occurs due to elevated
urine albumin excretion rate and reduced glomerular filtration rate. Studies on animals have
shown that alpha-lipoic acid (ALA) supplementation can reduce the development of DN.

Objectives:
We performed a systematic review and meta-analysis to examine the effects of ALA
supplementation on biological indices (albumin, creatinine, etc.) indicative of human DN.

Methods:
The search procedure included PubMed Central, Embase, Cochrane Library (trials), and
Web of Science (protocol registration: INPLASY202060095).

Results:
We found that ALA supplementation decreased 24h urine albumin excretion rate in patients
with diabetes (standardized mean difference=-2.27; confidence interval (CI)=(-4.09)-(-0.45);
I2=98%; Z=2.44; p=0.01). A subgroup analysis revealed that the results of studies examining only
ALA did not differ from those examined ALA in combination with additional medicines (Chisquared=
0.19; p=0.66; I2=0%), while neither ALA nor ALA plus medication had an effect on 24h
urine albumin excretion rate (p>0.05). Also, ALA supplementation decreased urine albumin mg/l
(mean difference (MD)=-12.95; CI=(-23.88)-(-2.02); I2=44%; Z=2.32; p=0.02) and urine albumin
to creatinine ratio (MD=-26.96; CI=(-35.25)-(-18.67); I2=0%; Z=6.37; p<0.01) in patients with diabetes.
When the studies examining ALA plus medication were excluded, it was found that ALA
supplementation had no effect on urine albumin mg/l (p>0.05) but did significantly decrease urine
albumin to creatinine ratio (MD=-25.88, CI=(34.40-(-17.36), I2=0%, Z=5.95, p<0.00001).

Conclusion:
The available evidence suggests that ALA supplementation does not improve biological
indices that reflect DN in humans. Overall, we identified limited evidence, and therefore, the
outcomes should be considered with caution.
Direct (New) Oral Anticoagulants (DOACs): Drawbacks, Bleeding and Reversal
Authors: Karcioglu Ozgur , Zengin Sehmus , Ozkaya Bilgen , Ersan Eylem , Yilmaz Sarper , Afacan Goksu , Abuska Derya , Hosseinzadeh Mandana , Yeniocak Selman 
Published: September 2021

Background and Objective:
Direct (new) Oral Anticoagulants (DOACs) have emerged
as a contemporary and promising option in the treatment of thromboses and VTE, while protecting
the coagulation cascade against untoward bleeding events. They are used in the management and
prophylaxis of Venous Thromboembolism (VTE) and other thrombotic diseases. The most prominent
complication of these agents is bleeding. These agents have similar or lower rates of major intracranial
hemorrhages, while they had a higher risk of major gastrointestinal bleeding when compared
to warfarin. This manuscript is aimed to revise and update the literature findings to outline
the side effects of DOACs in various clinical scenarios.

Methods:
A narrative review of currently published studies was performed. Online database searches
were performed for clinical trials published before July 2021, on the efficacy and adverse effects
attributed to the anticoagulant treatment, especially DOACs. A literature search via electronic
databases was carried out, beginning with the usage of the agents in the Western Languages papers.
The search terms initially included direct (new) oral anticoagulants, dabigatran, rivaroxaban,
apixaban, edoxaban, idarucizumab, andexanet, prothrombin complex concentrates, and fresh
frozen plasma. Papers were examined for methodological soundness before being included.

Results:
Severe bleeding episodes require aggressive interventions for successful management.
Therefore, bleeding should be evaluated in special regard to the location and rate of hemorrhage,
and total volume of blood loss. Patient's age, weight and organ dysfunctions (e.g., kidney/liver failure
or chronic respiratory diseases) directly affect the clinical course of overdose.

Conclusion:
Management recommendations for hemorrhage associated with DOAC use vary, depending
on the class of the culprit agent (direct thrombin inhibitor vs. FXa inhibitor), the clinical
status of the patient (mild/ moderate vs. severe/life-threatening), and capabilities of the institution.
Specific reversal agents (i.e., idarucizumab and andexanet alfa) can be used if available, while prothrombin
complex concentrates, fresh frozen plasma and/ or tranexamic acid can also be employed
as nonspecific replacement agents in the management of DOAC-related bleeding diathesis.
Acceptability of a Brief Web-Based Theory-Based Intervention to Prevent and Reduce Self-harm: Mixed Methods Evaluation
Authors: Keyworth Chris , O'Connor Rory , Quinlivan Leah , Armitage Christopher J 
Published: September 2021

Background
The volitional help sheet (VHS) for self-harm equips people with a means of responding automatically to triggers for self-harm with coping strategies. Although there is some evidence of its efficacy, improving acceptability and making the intervention available in a web-based format may be crucial to increasing effectiveness and reach.

Objective
This study aims to use the Theoretical Framework of Acceptability (TFA) to explore the acceptability of the VHS, examine for whom and under what circumstances this intervention is more or less acceptable, and develop a series of recommendations for how the VHS can be used to support people in reducing repeat self-harm.

Methods
We explored acceptability in two phases. First, our patient and public involvement partners evaluated the original VHS from a lived experience perspective, which was subsequently translated into a web-based format. Second, a representative sample of adults in the United Kingdom who had previously self-harmed were recruited via a YouGov survey (N=514) and were asked to rate the acceptability of the VHS based on the seven constructs of the TFA, namely, affective attitude, burden, perceived effectiveness, ethicality, intervention coherence, opportunity costs, and self-efficacy. Data were analyzed using descriptive statistics, one-tailed t tests, and binary logistic regression. A directed content analysis approach was used to analyze qualitative data.

Results
Participants in the web-based survey rated the VHS as positive (affective attitude; t457=4.72; P<.001); were confident using it (self-efficacy; t457=9.54; P<.001); felt they did not have to give up any benefits, profits, or values when using it (opportunity costs; t439=−15.51; P<.001); understood it and how it worked (intervention coherence; t464=11.90; P<.001); and were confident that it would achieve its purpose (perceived effectiveness; t466=2.04; P=.04). The TFA domain burden appeared to be an important indicator of acceptability. Lower levels of perceived burden when using the VHS tool were more prevalent among younger adults aged 18-24 years (OR 3.63, 95% CI 1.50-8.78), people of White ethnic background (OR 3.02, 95% CI 1.06-8.613), and people without a long-term health condition (OR 1.53, 95% CI 1.01-2.30). Perceived modifications to further improve acceptability included improved formatting (burden), the feature to add new situations and responses or amend existing ones (ethicality), and clearer instructions and further detail about the purpose of the VHS (intervention coherence).

Conclusions
Our findings show high levels of acceptability among some people who have previously self-harmed, particularly among younger adults, people of White ethnic backgrounds, and people without long-term health conditions. Future research should aim to improve acceptability among older adults, people from minority ethnic groups, and people with long-term health conditions.

Authors: Ekawati Rosyida , Puspitasari Desi , Hanifa Siti 
Published: September 2021

The objective of study is to explore the relationship between visual and verbal elements within the frame of multimodal discourse analysis in Madura tourism promotion. Promotion in the form of moving images with verbal language makes it easier for readers and potential tourists to see tourist attractions more closely and realistically. This study is descriptive qualitative using 3 videos of Madura tourism promotion, in particular tourism promotions of Bangkalan, Pamekasan, and Sampang regencies on Madura Island, Indonesia. Only scene representing religious tourism as the data of this study in which there are 8 data of religious tourism images. There are two parts of data analysis: visual and verbal analyses. Visual semiotic mode of scenes and images were analyzed using visual grammar by Kress and van Leeuwen (2006). In addition, verbal data are all of utterances generated during the scenes and the still images were analyzed based on appraisal framework by Martin and White (2005) especially on the attitude system. Results show that tourism promotional videos use more than one mode of communication or semiotic system elements to create meaning through representational and interactive structures, compositional meanings, and verbal language. All of the compositions can come together to create messages to the public, in this case information about tourist attractions and their locations that represent the religiosity of Madura.

The purpose of this research is to explain about Sufism formulated by Sheikh Hamzah Fanshuri. He is quite famous in the 16th century AD Although the concept of Sufism Hamzah Fansuri already very old, but until now, this teaching is still studied in Aceh and in several other regions in Indonesia. Among the concepts of Hamzah Fansuri's Sufism that are still studied by many people is about the concept of existence. In the opinion of Sheikh Hamzah Fansuri, the essence of existence is one, namely the existence of God. Apart from the existence of God everything is not a real existence, but a reflection of the real existence. While this form is a relationship beamong matter, nature, asthma and af'al Allah. Regarding the existence of human beings, Sheikh Hamzah Fansuri explained that human beings are the lowest form, even so, they still have the opportunity to rise to a higher dignity.
