Measurement and Comparison of Variance in the Performance of Algerian Universities using models of Returns to Scale Approach
Authors: Bebba Imane , Saci Ilyes Ben
Published: August 2022

This study aimed to measure and compare the performance of forty-seven Algerian universities, using models of returns to Scale approach, which is based primarily on the Data Envelopment Analysis  method. In order to achieve the objective of the study, a set of variables was chosen to represent the dimension of teaching. The variables consisted of three input variables, which were:  the total number of students  in the undergraduate level, students in the post graduate level and the number of permanent professors. On the other hand, the output variable was represented by the total number of students holding degrees of the two levels. Four basic models for data envelopment analysis method were applied. These were: (Scale Returns), represented by input-oriented and output-oriented constant returns and input-oriented and output-oriented  variable returns. After the analysis of data, results revealed that eight universities achieved full efficiency according to constant returns to scale in both input and output orientations. Seventeen universities achieved full efficiency according to the model of input-oriented returns to scale variable. Sixteen universities achieved full efficiency according to the model of output-oriented  returns to scale variable. Therefore, during the performance measurement, the size of the university, competition, financial and infrastructure constraints, and the process of resource allocation within the university  should be taken into consideration. Also, multiple input and output variables reflecting the dimensions of teaching, research, and community service should be included while measuring and assessing the performance of Algerian universities, rather than using two variables which do not reflect the actual performance of these universities.

Keywords: Performance of Algerian Universities, Data envelopment analysis method , Constant returns to scale, Variable returns to scale, Input-orientation, Output-orientation.

Authors: Alves Josivan Leite , Chagas Milton Jarbas Rodrigues , Faria Emília de Oliveira , Caldeira-Pires Armando de Azevedo
Published: August 2022

O modelo linear de produção e consumo prejudica o meio ambiente e acelera a escassez de recursos naturais. Em contrapartida, a Economia Circular (EC) surge como modelo que visa manter produtos, componentes e materiais em seu mais alto nível de utilidade e valor o tempo todo. Esta pesquisa busca responder à seguinte questão-problema: como a literatura internacional aborda a relação entre Energias Renováveis e Economia Circular em um contexto industrial? Como objetivo geral, tem-se: identificar, na literatura internacional, como os termos Energias Renováveis e Economia Circular se relacionam no contexto industrial. A metodologia aplicada consistiu em uma revisão sistemática da literatura associada à bibliometria nas bases de dados da Scopus e Web of Science, aplicando os termos: “renewabl* energ*” AND “circular economy” AND “industr*”. Os indicadores bibliométricos foram analisados com o auxílio dos softwares MINITAB e VOSviewer. A partir da amostra final, de 88 artigos, os países que mais se destacaram em número de publicações foram a Itália, seguida pela China, Alemanha e Reino Unido. Notou-se que os anos com maior quantidade de publicações foram 2018, 2019 e 2020, sendo que a primeira publicação surgiu em 2012. Dentre os principais resultados, verificou-se que as pesquisas, em sua maioria, são estudos de casos que diagnosticam uma realidade e propõem soluções eficientes junto aos processos produtivos e a redução de impactos ambientais. Por fim, concluiu-se que a Economia Circular é um modelo progressista de produção e consumo, que respeita a limitação dos recursos naturais, ao passo que atende às necessidades humanas.
Os desafios da atuação dos mediadores sociais na ATER para inovação e inclusão produtiva de agricultores familiares no Estado do Tocantins
Authors: Sousa Diego Neves de , Pôrto-Júnior Francisco Gilson Rebouças
Published: August 2022

O fato de as políticas públicas de inclusão produtiva serem orientadas por diferentes referenciais força os mediadores sociais a articulá-las e torná-las coerentes para o público beneficiário, o que se torna uma tarefa que eles nem sempre estão aptos a realizar. Ademais, dentre os próprios mediadores, também não existe uma concepção única do que se entende por inclusão produtiva. Neste sentido, a partir de um diálogo com a abordagem da sociologia da tradução (CALLON, 1981; 1986; LATOUR, 2000), tem-se como objetivo analisar o papel dos mediadores sociais nos processos de inovação e inclusão produtiva de agricultores familiares no contexto da extensão rural do estado do Tocantins. O estudo é qualitativo com o uso da técnica de entrevista. Conclui-se que o serviço de extensão rural tem papel estratégico em promover a inclusão produtiva de agricultores familiares ao fomentar a inovação e facilitar o acesso às políticas públicas específicas que contemplem a realidade deles. Para isso, os mediadores precisam se posicionar no processo de tradução mais como “comunicadores” do que “transmissores”, para que possam avançar na definição de referenciais mais específicos de sua atuação em consonância à diversidade de segmentos sociais da agricultura familiar e também na unificação de discursos e ações entre os atores partícipes do processo intervencionista.
Internal and external sovereignty of post-Soviet unrecognized states
Authors: Kolosov V.
Published: August 2022

The article studies internal and external sovereignty of unrecognized or partially recognized post-Soviet states through the use of empirical analysis of quantitative data and critical analysis of subjective factors. It analyzes statistical and other information that reflects the demographic and socio-economic situation, foreign economic relations of such entities, and their impact on neighboring countries and regions. This is combined with the critical study of public opinions and popular identities based on surveys and 13 focus groups conducted in the fall of 2020 in Transnistria and Abkhazia. In all post-Soviet de facto states, the population has noticeably decreased (except for Nagorno-Karabakh before the 2020 war). The reason for the outflow of residents was the inability of such entities to provide citizens with decent incomes and their poor performance in economic competition with neighboring countries and regions, reflected in the dynamics of the key indicators per capita in terms of purchasing power parity. However, the economic and demographic situation cannot explain the sustainability of such entities. Strong political identity of citizens and their loyalty to the ruling regimes serve as the main basis for, and essential elements of, internal sovereignty. Participants of surveys highly value independence. They believe that it presumes economic independence, improved well-being, and the development of full-fledged international relations that helps to strengthen external sovereignty. Some respondents expressed disappointment with the fact that these goals have not been achieved in the course of 30 years. The geopolitical vision of the world by residents of post-Soviet de facto states is “Russia-centric”, although Russia is far from being idealized. In conclusion, the risks that Russia faces in connection with post-Soviet de facto states and with Moscow's involvement in the respective conflicts are assessed.
The beginnings of laboratory medicine in the light of Polish medical press in the Partition period
Authors: Koszuda Wiktoria
Published: August 2022

Problematyka diagnostyki laboratoryjnej poruszana na łamach dziewiętnastowiecznych polskich czasopism lekarskich torowała drogę wszelkim działaniom na rzecz zakładania laboratoriów analiz lekarskich. Z biegiem czasu wzrastała świadomość lekarzy co do znaczenia badań laboratoryjnych w rozpoznawaniu i różnicowaniu chorób. Najważniejsze czasopisma lekarskie okresu zaborów, a więc: „Nowiny Lekarskie”, „Medycyna”, „Kronika Lekarska” i „Przegląd Lekarski”, zamieszczały prace polskich i zagranicznych autorów na temat analiz laboratoryjnych materiału biologicznego. Artykuły o medycynie laboratoryjnej docierały do polskich lekarzy od 1847 r., w którym wydano pierwszy numer „Tygodnika Lekarskiego”. W drugiej połowie XIX w. analizy laboratoryjne coraz częściej były podstawą rozpoznawania jednostek chorobowych.

Komentarz wprowadza w problematykę listów, które napisały do Seweryna Gałęzowskiego (1801-1878) dwie jego pacjentki, Anna Laskiewicz i Rozalia z Bispingów Wessel. W tym czasie Gałęzowski przebywał na emigracji w Paryżu, dlatego chore kobiety mogły uzyskać od niego poradę lekarską tylko drogą korespondencyjną. Listy te są godne uwagi jako przykład dziewiętnastowiecznej narracji pacjentów o chorobie, a ponadto jako obraz życia ziemian w zaborze rosyjskim w okresie międzypowstaniowym.

Authors: Terry Stephanie , Krüger Ana , Lima Paulo de Mello Tavares , Gruninger Robert , Abbott Wade , Beauchemin Karen
Published: August 2022

Several red seaweeds have shown to inhibit enteric CH4 production; however, adaptation of fermentation parameters to their presence is not well understood. The objective of this study was to examine the effect of three red seaweeds (Asparargopsis taxiformis, Mazzaella japonica, Palmaria mollis) on in vitro fermentation, CH4 production, and adaptation using the rumen simulation technique (RUSITEC). The experiment was conducted as a completely randomized design with four treatments, duplicated in two identical RUSITEC apparatus equipped with eight fermenter vessels each. The four treatments included the control (barley straw and barley silage) and the three red seaweeds added to the control diet at 2% diet DM. The experimental period was divided into four phases including a baseline phase (d 0-7; no seaweed included), adaptation phase (d 8-11; seaweed included in treatment vessels), intermediate phase (d 12-16) and a stable phase (d 17-21). The digestibility of organic matter (P = 0.04) and neutral detergent fibre (P = 0.05) was decreased by A. taxiformis during the adaptation phase, but returned to control levels in the stable phase. A. taxiformis supplementation resulted in a decrease (P < 0.001) in molar proportions of acetate, propionate and total volatile fatty acid (VFA) production, with an increase in molar proportions of butyrate, caproate, and valerate; the other seaweeds had no effect (P > 0.05) on molar proportions or production of individual VFA. A. taxiformis was the only seaweed to suppress CH4 production (P < 0.001), with the suppressive effect increasing (P < 0.001) across phases. Similarly, A. taxiformis increased (P < 0.001) the production of hydrogen (H2, %, mL/d) across the adaptation, intermediate and stable phases, with the intermediate and stable phases having greater H2 production than the adaptation phase. In conclusion, M. japonica and P. mollis did not impact rumen fermentation or inhibit CH4 production within the RUSITEC. In contrast, we conclude that A. taxiformis is an effective CH4 inhibitor and its introduction to the ruminal environment requires a period of adaptation; however, the large magnitude of CH4 suppression by A. taxiformis inhibits VFA synthesis, which may restrict production performance in vivo.
User Authentication and Authorization Framework in IoT Protocols
Authors: Al-refai Hasan , Alawneh Ali
Published: August 2022

The Internet of Things (IoT) has become one of the most attractive domains nowadays. It works by creating a special network between physical devices such as vehicles, home equipment, and other items. In recent days, the common technologies of communication such as Wi-Fi and 2G/3G/4G cellular are insufficient for the IoT networks because they are designed to serve appliances with immense processing capabilities such as laptops and PCs. Moreover, most of these technologies are centralized and use an existing infrastructure. Currently, the new communication technologies such as Z-Wave, 6LowPAN, and Thread are dedicated to the IoT and have been developed to meet its requirements. These technologies can handle many factors such as range, data requirements, security, power demands, and battery life. Nevertheless, the security issues in IoT systems have major concerns and matters because vulnerabilities in such systems may result in fatal catastrophes. In this paper, an enhanced IoT security framework for authentication and authorization is proposed and implemented to protect the IoT protocols from different types of attacks such as man-in-the-middle attack, reply attack, and brute force attack. The proposed framework combines an enhanced token authentication that has identity verification capabilities and a new sender verification mechanism on the IoT device side based on time stamp, which in turn can mitigate the need for local identity verification methods in IoT devices. The proposed IoT security framework is tested using security analysis with different types of attacks compared with previous related frameworks. The analysis shows the high capability of the proposed framework to protect IoT networks against many types of attacks compared with current available security frameworks. Finally, the proposed framework is developed using Windows application to simulate the framework phases, check its validity through the real network, and calculate the payload time is adds.

Authors: Zedde Marialuisa , Portaro Giacomo , Ferri Laura , Cavallieri Francesco , Napoli Manuela , Moratti Claudio , Piazza Fabrizio , Valzania Franco , Pascarella Rosario
Published: August 2022

Background: Anemia is one of the most frequent diseases worldwide, affecting a third of the general population. Anemia in general and in particular, iron-deficient anemia (IDA), has been associated to a higher risk of thrombotic manifestations, including ischemic stroke and cerebral venous thrombosis (CVT), as well as systemic extra cerebral arterial and venous thrombosis. Despite these data, anemia is seldom considered as an etiological factor of stroke. Methods: An individual case encompassing all known neurovascular and systemic arterial and venous thrombotic manifestations related to IDA is presented with the focus on clinical reasoning issues in the diagnostic pathways, starting from the neuroradiological signs. The main questions have been identified and addressed in a narrative review of the most relevant data in the literature from a pragmatic and clinical viewpoint. Results and Discussion: The presented case concerns a 46 years old man admitted to the Stroke Unit because of acute is-chemic stroke with multiple thrombi in large intracranial and extracranial vessels, multifocal ischemic lesions in several arterial territories and the concurrent finding of asymptomatic CVT, pulmonary embolism with lung infarction and aortic thrombosis. An extended diagnostic work-up excluded the main etiologies (arterial dissection, cardiac embolism, genetic and acquired prothrombotic disorders, as cancer and antiphospholipid syndrome), except for a severe IDA, such as to require blood transfusions followed by anticoagulant therapy for the several thrombotic manifestations. Neuroimaging and systemic vascular findings have been analyzed and the main issues proposed by the case in the diagnostic pathway have been identified and discussed in a pragmatic clinical road map reviewing the data provided by the literature. Conclusions: IDA is a common but treatable condition that, independently or synergically, may increase the risk of thrombotic events. The diagnostic and therapeutic approach has not yet defined and each case should be individually addressed in a pragmatic clinical road map.
Snakemake Workflows for Long-read Bacterial Genome Assembly and Evaluation
Authors: Menzel Peter
Published: August 2022

With the advancement of long-read sequencing technologies and their more widespread use for bacterial genomics, several methods for generating genome assemblies from error-prone long reads have been developed. These are complemented by various tools for assembly polishing using either long reads, short reads, or reference genomes. End users are therefore left with a plethora of possible combinations of programs for obtaining a final trusted assembly. Hence, there is also the need for measuring completeness and accuracy of such assemblies, for which, again, several evaluation methods implemented in various programs are available. In order to automatically run all these programs, I developed two workflows for the workflow management system Snakemake for bacterial genome assembly and evaluation of assemblies, which provide end users with an easy-to-run method for both tasks. The workflows are available as open source software under the MIT license at https://github.com/pmenzel/ont-assembly-snake and https://github.com/pmenzel/score-assemblies.
Legal Policy on the Protection of the Right to Health During the Covid-19 Pandemic in France
Authors: Savitri Dewi Nurul
Published: August 2022

France has regulated the health system in great detail in some laws and regulations, but these regulations are insufficient to face the pandemic of Covid-19. This study aims to describe and analyze legal policies to protect health rights during the COVID-19 pandemic in France. It employs a normative legal research method with data sources such as the Declaration of human and citizen’s rights of 1789, the French Constitution of 1958, and laws and decisions of the French Constitutional Council. Since the Covid-19 pandemic erupted, French legislators have implemented adequate measures to prevent its spread.. The study results indicate that since the Covid-19 pandemic spread, French legislators have implemented adequate measures to prevent the spread of the virus through the appointment of the French Constitutional Council as the protector and guarantor of the fundamental rights of citizens through a system of judicial review. The control of proportionality in the system of judicial review is essential to strike a balance between the public interest of society and the rights of individuals to implement the adaptations necessary to protect public health, particularly during the Covid-19 pandemic.

This study aims to analyze the President's power and the threat attached to it during the transition of the inter-election period and the concept of the legal framework in Indonesia's legal system. It also provides the need to be performed in the future to ensure that the President does not abuse this power. The matter raises a series of problems regarding the government's authority during the election transition period. This research will provide comparative studies with Ghana, Liberia, and the United States to understand the President's power in the Indonesian constitutional system. This research was conducted using doctrinal research methods, or normative legal research. In reviewing a legal issue, a doctrinal research method analyzes positive law, related cases, and other relevant references. The results showed that the President's power during the election transition period needs to be regulated in the constitution. Furthermore, the arrangement has to be enforced technically in the form of a presidential transition law.

Published: August 2022

The 2017 Duck Unmanned Aircraft Systems (UAS) Pilot Experiment was conducted by the US Army Engineer Research and Development Center (ERDC), Coastal and Hydraulics Laboratory, Field Research Facility (FRF), to assess the potential for different UAS to support US Army Corps of Engineers coastal and flood risk management. By involving participants from multiple ERDC laboratories, federal agencies, academia, and private industry, the work unit leads were able to leverage assets, resources, and expertise to assess data from multiple UAS. This report compares datasets from several UAS to assess their potential to survey and observe coastal terrain and structures. In this report, UAS data product accuracy was analyzed within the context of three potential applications: (1) general coastal terrain survey accuracy across the FRF property; (2) small-scale feature detection and observation within the experiment infrastructure area; and (3) accuracy for surveying coastal foredunes. The report concludes by presenting tradeoffs between UAS accuracy and the cost to operate to aid in selection of the best UAS for a particular task. While the technology and exact UAS models vary through time, the lessons learned from this study illustrate that UAS are available at a variety of costs to satisfy varying coastal management data needs.
Automatic Measurement of the Dependence on Pressure and Temperature of the Mass Density of Drilling Fluids
Authors: Cayeux E.
Published: August 2022

Drilling fluids are subject to substantial variations in pressure and temperature while they are circulated in a well. These changes are so great that the mass density of the drilling fluid varies significantly during circulation. Accurate estimation of the hydrostatic and hydrodynamic pressures therefore requires a reliable model of the pressure and temperature dependence of the mass density of the drilling fluid. Usually, the mass density of a drilling fluid is measured manually with a mud balance. The pressure and temperature dependence of the mass density of the fluid [i.e., its pressure, volume, and temperature (PVT) behavior] is then calculated from a PVT model of its components and their relative proportions. However, variations in the composition of the fluid mix and uncertainties in the PVT behavior of each component may lead to inaccuracies. To overcome these limitations, an apparatus has been designed to measure the PVT behavior of the drilling fluid directly and automatically. The setup measures both the mass density and the speed of sound of the fluid at specific conditions of pressure and temperature. It is possible to estimate the adiabatic compressibility from the speed of sound in the liquid mix. The device utilizes a heat exchanger from which the specific heat capacity of the drilling fluid can be derived. The isothermal compressibility can be calculated by combining the specific heat capacity and the adiabatic compressibility. While estimating the specific heat capacity using the heat exchanger, the thermal conductivity of the fluid is also estimated as a byproduct. A PVT model of the drilling fluid is obtained by combining measurements made at different conditions of pressure and temperature. The automatic and continuous provision of drilling fluid PVT behavior enhances the precision of model predictive drilling control systems and, at the same time, can simplify their configuration, therefore making them more accessible to any drilling operation.
An Indirect Approach for Flow Pattern Transition Identification Inside a Low-Specific-Speed Centrifugal Pump with Experimental Verification and Theoretical Modeling
Authors: Li Yuanyuan , Zhu Jianjun , Zeng Hao , Zhang Yongxue , Lu Yingda , Fan Yilin , Zhu Haiwen
Published: August 2022

Of significant importance to the multiphase flow, the gas/liquid two-phase flow patterns and the transition boundaries between them are extremely difficult to be characterized inside the centrifugal pumps because the steel-made nontransparent casing shrouds the impeller’s flow passages. How to visualize the internal flow patterns within the rotating impeller has drawn considerable attention. In this study, an indirect approach proposed by Gamboa and Prado (2011) to recognize the gas/liquid flow patterns in the centrifugal impeller via inflection characteristics of H-Q performance curves is used and verified by both experimental tests and numerical simulations. To further validate the indirect flow pattern recognition approach to a low-specific-speed centrifugal pump, the acrylic-made transparent impeller was adopted to conduct experimental testing, in which the internal two-phase flow pattern can be visualized by a high-speed camera. The 3D numerical simulation was performed and compared with corresponding visualization experiments to illustrate the two-phase flow structures. The preliminary results reveal that the inflection characteristics on the H-Q performance curves of the centrifugal pump can be regarded as the flow pattern transition boundaries under various flow conditions. The experiments and simulations conducted for this paper further validated an existing mechanistic model to predict flow pattern transitions.

Since real-world data is often inaccurate and working with fuzzy data and Z-numbers arevery important and necessary, in the real world we need to rank and compare data. Inthis paper, we introduce a new method for ranking Z-numbers. This ranking algorithm isbased on centroid point.We evaluate distance between centroid point, and based on this distance, we rank theZ-numbers.We use this method in two practical examples. First in ranking the return on assets ofTehran stock exchange, and second, in ranking of factors affecting the productivity oftourism security.The advantage of this method over conventional fuzzy methods is considering uncertainty,and allocating credit in the opinion of experts to estimate fuzzy parameters.

Species composition and abundance of lizard populations was studied in the historical monuments such as the Devanahalli fort of the Bengaluru North City region, Bengaluru, India. The quadrants laid in the fort was surveyed for the estimation of the population density, abundance, sex ratio, frequency and distribution of the lizards in the Devanahalli fort. A total of nine species of lizards were recorded during the study, thus highlighting the significance of historical forts in acting as important urban habitats for reptiles. The reptilian fauna of the historical monuments such as forts, temples and archeological sites were found to be more distinct than the rest of the urban landscapes. In addition to this, notes on the morphometric analysis, behavioral patterns and natural history of recorded lizards was observed. Therefore, the abundance of the lizard populations in the historical fort’s call for its special concern for care because their archeological importance and will be of use for urban planning and conservation.

Purpose: Lymphovascular invasion (LVI) and perineural invasion (PNI) can indicate poor survival outcomes in colorectal cancer, but few studies have focused on stage III colon cancer. The current study aimed to confirm the prognostic value of LVI and PNI and identify patients who could benefit from a complete duration of adjuvant chemotherapy based on the two pathological factors.Methods: We enrolled 402 consecutive patients with stage III colon cancer who received colon tumor resection from November 2007 to June 2016 at Sun Yat-sen University Cancer Center. Survival analyses were performed by using Kaplan–Meier method with log-rank tests. Risk factors related to disease-free survival (DFS) and overall survival (OS) were identified through Cox proportional hazards analysis.Results: 141 (35.1%) patients presented with LVI, and 108 (26.9%) patients with PNI. The LVI-positive group was associated with poorer 3-year DFS (86.5% vs. 76.3%, P=0.001) and OS (96.0% vs. 89.1%, P=0.003) rates compared with the LVI-negative group. The PNI-positive group showed a worse survival outcome compared with the PNI-negative group in 3-year DFS rate (72.5% vs. 86.7%, P < 0.001). Moreover, LVI-positive group present better 3-year DFS and OS rate in patients completing 6–8 cycles of adjuvant chemotherapy than those less than 6 cycles (3-year DFS: 80.0% vs. 64.9%, P=0.019; 3-year OS: 93.2% vs. 76.3%, P = 0.002).Conclusions: LVI is a superior prognostic factor to PNI in stage III colon cancer patients undergoing curative treatment. Furthermore, LVI also represents an effective indicator for adjuvant chemotherapy duration.

BackgroundA novel variant of SARS-CoV-2, the Delta variant of concern (VOC), on disease severity is very unclear. In this retrospective study, we compared the clinical characteristics and the outcomes of patients infected with the Delta VOC and with wild-type strains during the local outbreak in Xi'an and Wuhan, China.MethodsThe clinical information pertaining to the 2927 cases (between February 10 and March 8, 2020) infected with wild-type strains and the 993 cases (between December 22, 2021and February 17, 2022) infected with the Delta VOC were extracted. The clinical characteristics and outcomes were compared the cohort of wild-type infection with the cohort of Delta VOC.ResultsAmong patients younger than 18 years old, the proportion of patients infected with the Delta VOC was significantly higher than that of patients infected with wild-type strains (12.2% vs. 0.3%). In cases with mild and moderate illness, the proportion of patients was higher in the Delta VOC group than that in the wild-type strain (40.9% and 56.6% vs. 0.70% and 3.10%). However, in severe and critical patients, the proportion of patients was significantly less in the Delta VOC group than that in the wild-type strain (1.6% and 0.9% vs. 24.2% and 72.0%). In cases with severe or critical illness, and in the Delta VOC cohort or the wild-type cohort, the prognosis of patients with lymphocytes blood levels that gradually rising is good after treatment, while the prognosis of patients with lymphocytes blood levels that remain low is poor and even death(p<0.001). The Cox regression analysis revealed that the infection with the lineage of the wide-type strain had a higher risk than the Delta VOC in deteriorating to critical illness (hazards ratio 2.54[95%CI 1.279–5.026]; p = 0.008).ConclusionsUnder the two different anti-epidemic situations and anti-epidemic strategies, infection with the Delta VOC is characterized by younger patients, milder illness, and decreased risk of disease prognosis, compared with the SARS-CoV-2 wild-type lineage; lymphopenia is an effective predictor of deterioration in patients with Delta VOC and wild-type strains, calling for clinicians to understand of characteristics of them according to the different anti-epidemic situations and anti-epidemic strategies, and to guide clinical decision-making.

Background: Non-suicidal self-injury (NSSI) is a growing healthcare problem. Individuals with NSSI have an increased risk of suicidality. Because of stigma, they may self-injure in secret, which means they often seek help when events have escalated to suicidal ideation or a mental disorder. Previous studies have shown that interventions delivered via mobile phone applications have the potential to reduce self-injury. This protocol outlines a trial, which examines whether the Zero Self Harm-intervention, which is based on an app created for people with NSSI, can reduce the number of NSSI-episodes, suicide ideation, and depressive symptoms. Methods: The trial will be conducted as a 6-month 2-arm, parallel-group, multicentre, pragmatic, randomized clinical superiority trial. The intervention group will receive the app and instructions on how to use it, while the control group will be allocated to a waitlist and allowed to download the app after 6 months. Participants will be asked to complete questionnaires at 3- and 6 months after date of inclusion and the primary outcome is the number of NSSI-episodes during the last month, as measured at the 3 months follow-up with the Deliberate Self-Harm Inventory. A total of 280 participants, 140 in each arm, will be included.Discussion: This trial will assess the effectiveness of the Zero Self Harm-intervention to reduce the number of NSSI episodes. If effective, the app will have the potential to support to large group of people with NSSI. NSSI is stigmatised and often done in secret. Being both discreet and anonymous, the app might be an appealing option for support. In addition, people with current or former NSSI were involved in the development of the app. The app was developed with a focus on minimizing harm, not to end NSSI, which might also make the app appealing for a broader group of users.Trial registration: ClinicalTrials.gov, NCT04463654.

Published: August 2022

The intensification of mobile broadband services and user experience is explicitly dependent on increased battery life of user equipment (UE) and minimized delay in service. In 5G New Radio (NR), in addition to Discontinuous Reception (DRX) scheme, Bandwidth Part (BWP) switching plays a significant role in reducing UE power consumption. The dynamic bandwidth operation in BWP switching is power efficient as UE can adapt its operating bandwidth based on the traffic arrival. In this work, BWP switching based DRX mechanism is modeled as an MX/G/ 1 queue to trade-off between quality of service (QoS) and power saving in UE in 5G NR. Analytical and numerical results on the proposed model show it to be promising in minimizing power consumption and reducing delay in service of UE.
