Experience gained about Resistive Plate Chambers ageing from the ALICE Muon TRigger/IDentifier detector

The ALICE Muon IDentifier is composed of 72 single-gap bakelite Resistive Plate Chambers, which have been operational since 2009 in avalanche mode with a Tetrafluoroethane/Isobutane/Sulphur Hexafluoride gas mixture, undergoing counting rates of the order of tens of Hz/cm2.Here, the long-term performance and stability of the RPC system will be discussed, in terms of efficiency, dark current and dark rate. An assessment of potential signs of ageing observed in the detectors will be presented, together with a summary of the most common hardware problems experienced.

Use of a correction factor for the pulsecal subroutine used for pulse width calibration and identifying a hardware fault causing pulsecal to fail

Stroboscopic nutation has proved to be invaluable for pulse width calibration (P. S. C. Wu and G. Otting, Rapid pulse length determination in high-resolution NMR, J. Magn. Reson. 2005, 176, 115–119), though it is not without its issues. Herein it is proposed that a correction factor be applied to correct for the inaccuracy of the method which is dependent on the NMR system including the probe, observed nucleus, sample type set (solvent, concentration, ionic strength, etc.), temperature, etc. Poor performance of the stroboscopic nutation experiment was also found to be a harbinger of a serious hardware problem.

Superior versus anterior plating of midshaft clavicle fractures: 6 months follow up (union rates, risks, and complications: hardware irritation and need for removal)

Background Operative management of midshaft clavicle fractures is gaining popularity. The clavicle is a tubular bone with a flat lateral end. Open reduction and internal fixation could be achieved by the application of plates and screws either to the superior or anterior surface of the clavicle. However, there is no consensus in the literature to support one technique over the other. This study aims to compare the early functional and radiographic outcomes of anterior versus superior plating for the treatment of midshaft clavicle fractures. Patients and methods From March 2021 to November 2022, a prospective randomized clinical trial was conducted at our institute. We included all patients with isolated midshaft clavicle fractures. Thirty-six patients were randomized by the closed envelope technique, 18 were managed with superior plating (superior group), and the other 18 patients were managed using anterior plating (anterior group). All patients were followed up for 6 months. All patients were assessed clinically for union, range of motion, and functional scores. The secondary outcome measures included operative time, complications, hardware irritation, and the need for hardware removal or secondary procedure. Results The mean time to full union was 11.28 weeks in the anterior group and 11.72 weeks in the superior group. Mean constant shoulder score for the anterior group was 84.11 while for the superior group it was 82.67. No patients had skin and wound complications in the anterior group versus one patient in the superior group that got superficial infection successfully managed by repeated dressing and antibiotics. There was no statistically significant difference between superior and anterior plating regarding union, functional scores, return to ADLs, hardware problems, or complications. Conclusion Both superior and anterior plating of the clavicle fractures are safe treatment options for displaced midshaft clavicle fractures, and they lead to similar functional outcomes, functional scores, and complication rates. Moreover, the selection of the technique of plating depends on surgeon preferences.

Issues and Challenges Encountered by Police Officers in Automated Fingerprint Identification System Operation

Automated Fingerprint Identification Systems (AFIS) play a vital role in modern law enforcement by aiding in the identification and apprehension of criminals through fingerprint analysis. However, despite their significance, challenges in operating AFIS remain the main hindrance to its effective utilization. Thus, this study aims to investigate the issues and challenges faced by police officers in the Philippines with AFIS. Employing a convergent parallel mixed methods research design, quantitative data were collected through a survey questionnaire, while qualitative data were obtained through in-depth interviews. The study participants comprised six experienced Filipino police officers purposively chosen for their exposure to AFIS operations. The study uses the mixed method. Descriptive statistics and Mann-Whitney U Test were used during quantitative data analysis, while thematic analysis was used in analyzing qualitative data. The study findings revealed that the top challenge faced by police officers in the Philippines is comparing and storing fingerprints in the AFIS database, primarily due to insufficient training and technical support. Themes such as regular training, technical support, and continuous learning emerged to address the challenges related to fingerprint quality, technical issues, storage limitations, and hardware problems. The study also revealed that Filipino police officers encounter moderate challenges when operating AFIS, with variations depending on sex, age, and length of service. In conclusion, the study underscores the significance of continuous training, technical support, and effective communication for successful AFIS operations. Law enforcement agencies are urged to prioritize providing proper training and technical support to ensure accurate and reliable utilization of this technology in policing.

Combined Wrist Extensor Tenodesis and Tendon Transfers for Severe Spastic Flexed Wrist Deformity: Surgical Technique and Case Series.

Spastic wrist flexion deformities both limit the functional use of the hand for grasp and pinch producing a stigmatizing appearance. Tendon transfers and total wrist arthrodesis are treatment options for this condition depending on the patient's characteristics, the latter the most commonly used in patients with severe wrist flexion deformities. Tendon transfers alone in this scenario have the tendency for recurrent deformity due to tenorrhaphy failure or soft tissue creep and resultant loss of tension. Total wrist arthrodesis is a more invasive procedure, which can have hardware or fusion problems and that is irreversible. We propose a novel technique that incorporates a distally based wrist extensor tendon slip and suture tape tenodesis to the distal radius. The rationale of this technique is to act as a protective, internal splint to prevent recurrent deformity after primary or revision tendon transfer for moderate to severe spastic flexed wrist deformities, avoiding the need to perform a total wrist arthrodesis.

Along with the dynamic development of technology and the need for technology integration in today's learning, technology has become an important element in educational organizations. programs and applications that have been mastered by teachers, namely PowerPoint, Google Translate, Google Doc, the internet, and all forms of technological offerings can undoubtedly support the blended learning pattern which then becomes a learning necessity. Teachers' content and and pedagogical knowledge must be supported by their technological knowledge. The aim of this research is to conduct qualitative research by means of doing semi-structured interview and checking teachers' daily journals about technologies applied in their teaching and learning processes and also the problems of applying those technologies. It was found that there are some technologies commonly used as the instruments of teaching by those 10 teachers in their teaching and learning processes after the pandemic such as: Google Meet, Google Classroom, and WA Group. Next to that, it was also found that there are some common barriers experienced by the teachers in the application of those technologies, such as: hardware and software problems, connectivity, financial problem, protection of personal information, technical support, lack of face-to-face interaction, psychological problems, and language barrier. The result if this research is expected that it can be used as the basis to develop appropriate technologies for teaching English for students to support their CK and PK regarding the implementation of TPACK at school.

Awareness and level of digital literacy among students receiving health-based education

BackgroundBeing digitally literate allows health-based science students to access reliable, up-to-date information efficiently and expands the capacity for continuous learning. Digital literacy facilitates effective communication and collaboration among other healthcare providers. It helps to navigate the ethical implications of using digital technologies and aids the use of digital tools in managing healthcare processes. Our aim in this study is to determine the digital literacy level and awareness of our students receiving health-based education in our university and to pave the way for supporting the current curriculum with courses on digital literacy when necessary.MethodStudents from Acibadem University who were registered undergraduate education for at least four years of health-based education, School of Medicine, Nutrition and Dietetics, Nursing, Physiotherapy and Rehabilitation, Psychology, Biomedical Engineering, Molecular Biology, and Genetics were included. The questionnaire consisted of 24 queries evaluating digital literacy in 7 fields: software and multimedia, hardware and technical problem solving, network and communication/collaboration, ethics, security, artificial intelligence (A.I.), and interest/knowledge. Two student groups representing all departments were invited for interviews according to the Delphi method.ResultsThe survey was completed by 476 students. Female students had less computer knowledge and previous coding education. Spearman correlation test showed that there were weak positive correlations between the years and the “software and multimedia,” “ethics,” “interest and knowledge” domains, and the average score. The students from Nursing scored lowest in the query after those from the Nutrition and Dietetics department. The highest scores were obtained by Biomedical Engineering students, followed by the School of Medicine. Participants scored the highest in “network” and “A.I.” and lowest in “interest-knowledge” domains.ConclusionIt is necessary to define the level of computer skills who start health-based education and shape the curriculum by determining which domains are weak. Creating an educational environment that fosters females’ digital knowledge is recommended. Elective courses across faculties may be offered to enable students to progress and discuss various digital literacy topics. The extent to which students benefit from the digital literacy-supported curriculum may be evaluated. Thus, health-based university students are encouraged to acquire the computer skills required by today’s clinical settings.RegistrationThis study was approved by Acıbadem University and Acıbadem Healthcare Institutions Medical Research Ethics Committee (ATADEK) (11 November 2022, ATADEK registration: 2022-17-138) All methods were carried out in accordance with relevant guidelines and regulations. Informed consent was obtained from the participants.

Outcome Analysis of Fixed angle Locking Plate in Comminuted Patella Fractures : A Single Centre Prospective study from South India with Early Results.

Comminuted patella fractures pose a challenge to orthopaedic surgeons , since tension band wiring and cerclage is not effective and often lead to loosening of wires, hardware problem, dislocation of fracture and failure of osteosynthesis resulting in post-traumatic osteoarthritis and knee stiffness. The aim of this study is to evaluate the clinical outcome in patients with AO 34C2 and 34C3 highly comminuted patella fractures treated with unidirectional fixed angle titanium patella locking plate. Twelve patients who presented with AO 34C2 and 34C3 comminuted patella fractures, aged between 18-79 years were included in the study. All fractures were reduced and fixed with unidirectional angle fixed stable titanium patella locking plate. Knee range of motion and knee outcome survey activities of daily living scale (KOS-ADL) was used to evaluate the outcome. Union of fracture was achieved in all twelve patients. Mean flexion at final follow-up was 123° (110°-130°). None of the patients had extensor lag. One patient had hardware irritation which resolved at final followup. This technique serves as an effective option in highly comminuted patella fractures by providing excellent mechanical stability resulting in anatomical reduction , excellent functional outcome , lower incidence of hardware irritation or failure of osteosynthesis.

Актуальные проблемы сенсоров и аппаратного обеспечения коммерческих беспилотных авиационных систем

Использование беспилотных транспортных средств, особенно беспилотных авиационных систем, для решения широкого спектра задач коммерческих и государственных организаций в последние годы интенсифицировалось. Преднамеренное или непреднамеренное искажение данных БАС потенциально может привести к опасным инцидентам техногенного характера с угрозой жизни и здоровью людей. Соответственно, возрастает потребность в обеспечении кибербезопасности таких систем в целом и защиты данных, необходимых для их корректного функционирования, в частности. Традиционные методы обеспечения безопасности не всегда подходят для сенсоров и аппаратного обеспечения систем беспилотного транспорта из-за целого ряда ограничений и особенностей функционирования. Настоящая статья открывает цикл публикаций, посвященных информационной безопасности БАС. Целью настоящей статьи является анализ векторов атак на сенсоры и их каналы, а также изучение аппаратного обеспечения БАС. Проведен обзор методов защиты от подобных атак. В работе применялись методы контент-анализа и эксперименты с коммерческими беспилотными авиационными системами, доступными для гражданских пользователей. В результате был разработан систематизированный перечень атак на сенсоры и аппаратное обеспечение, оформленное в виде таблиц в данной статье. The use of unmanned vehicles, especially unmanned aerial systems (UAS) for a wide range of tasks of commercial and government organizations has intensified in recent years. Intentional or unintentional distortion of UAS data can potentially lead to dangerous man-made incidents with a threat to human life and health. Accordingly, there is an increasing need for ensuring the cybersecurity of such systems in general and protecting the data necessary for their correct functioning, in particular. Traditional security methods are not always suitable for sensors and hardware of unmanned vehicle systems due to a number of limitations and features of operation. With this article, the authors open a series of articles on UAS information security. The purpose of this article is to analyse attack vectors on sensors and their channels, as well as UAS hardware. In addition, the authors reviewed methods of protection against such attacks. In their work, the authors applied content analysis methods and experiments with real commercial unmanned aerial systems available to civilian users. As a result, the authors have developed a systematic list of attacks on sensors and hardware, presented in the form of tables in this article.

Alarm reduction and root cause inference based on association mining in communication network

With the growing demand for data computation and communication, the size and complexity of communication networks have grown significantly. However, due to hardware and software problems, in a large-scale communication network (e.g., telecommunication network), the daily alarm events are massive, e.g., millions of alarms occur in a serious failure, which contains crucial information such as the time, content, and device of exceptions. With the expansion of the communication network, the number of components and their interactions become more complex, leading to numerous alarm events and complex alarm propagation. Moreover, these alarm events are redundant and consume much effort to resolve. To reduce alarms and pinpoint root causes from them, we propose a data-driven and unsupervised alarm analysis framework, which can effectively compress massive alarm events and improve the efficiency of root cause localization. In our framework, an offline learning procedure obtains results of association reduction based on a period of historical alarms. Then, an online analysis procedure matches and compresses real-time alarms and generates root cause groups. The evaluation is based on real communication network alarms from telecom operators, and the results show that our method can associate and reduce communication network alarms with an accuracy of more than 91%, reducing more than 62% of redundant alarms. In addition, we validate it on fault data coming from a microservices system, and it achieves an accuracy of 95% in root cause location. Compared with existing methods, the proposed method is more suitable for operation and maintenance analysis in communication networks.

Implementation of Simple Additive Weights To Determine Priorities For The Resolution of Information Technology Problems

The Regional Secretariat of West Java Province (Setda Jabar) is a government agency within the local government environment in West Java Province. Along with the development of information technology, using technology such as computers and the internet in a government agency is very important to support work. There are times when devices and systems do not work correctly, such as internet disturbances and computer software and hardware problems handled by technicians. Technicians not only manage information technology infrastructure at the West Java Regional Secretariat but also manage information technology infrastructure in three (3) official houses. Technicians are also faced with an organizational structure with many bureaus and sections. There is yet to be a definite procedure in the complaint reporting process. There is no helpdesk system as a reporting medium. With the many bureaus, the number of information technology facilities served so that technicians find it difficult to determine the priority of the work that must be served first. Given these problems, a Decision Support System approach uses the Simple Additive Weight method by using determining criteria and weights. The criteria used include Work Units, Positions, Types of Complaints, and Official Notes. The system development method used is Object Oriented Analysis Design (OOAD). This system is expected to assist technicians in determining services that match their needs and situations.

Informal Practices of Localizing Open Educational Resources in Ghana

Research on the use of Open Educational Resources (OER) often notes the potential benefits for users to revise, reuse, and remix OER to localize it for specific learners. However, a gap in the literature exists in terms of research that explores how this localization occurs in practice. This is a significant gap given the current flow of OER from higher-income countries in the Global North to lower-income countries in the Global South (King et al., 2018). This study explores how OER from one area of the world is localized when it is used in a different cultural context.
 Findings indicated complex encounters with decontextualized content and a variety of localization practices. Participants experienced challenges with technology due to low bandwidth and hardware problems, as well as language problems given Ghana’s history of colonial rule. Native speakers of Twi are less proficient reading Twi than their national language, English. As facilitators worked to overcome these challenges, they were most likely to informally localize content in intuitive ways during the class based on students’ needs. Informal, in-the-moment practices included translating content into Twi, persisting through technological challenges, using local stories and pictures, localizing through discussion, and teaching responsively. These findings have implications for designers to design collaboratively with technological and linguistic flexibility for localization. More research on the practice of OER localization would refine our understanding of how OER is localized and what barriers and affordances exist to this practice.

Radial versus dorsal plating for trapeziometacarpal arthrodesis: a comparative biomechanical study.

Trapeziometacarpal arthrodesis is used for the treatment of advanced arthritis. Insufficient stabilization of the joint may lead to nonunion or hardware problems after arthrodesis. The purpose of this study was to compare the biomechanical properties of dorsal versus radial plate fixation of the trapeziometacarpal joint in ten pairs of fresh-frozen cadaveric hands. The biomechanical performance of each group was measured for stiffness in extension and flexion and load to failure using cantilever bending tests. The stiffness in extension was lower in the dorsally positioned group than in the radially positioned group (12.1 versus 15.2 N/mm, respectively). Load to failure was comparable between both groups (53.9 versus 50.9 N, respectively). A radially positioned locking plate for trapeziometacarpal arthrodesis may be biomechanically advantageous.

Integration of the Vision of People With Diabetes Into the Development Process to Improve Self-management via Diabetes Apps: Qualitative Interview Study

Diabetes is a major global epidemic and serious public health problem. Diabetes self-management is a 24/7 challenge for people with type 1 diabetes that influences their quality of life (QoL). Certain apps can support the self-management of people with diabetes; however, current apps do not meet the needs of people with diabetes appropriately, and their safety is not ensured. Moreover, there are a multitude of hardware and software problems associated with diabetes apps and regulations. Clear guidelines are required to regulate medical care via apps. In Germany, apps must undergo 2 examination processes to be listed in the Digitale Gesundheitsanwendungen directory. However, neither examination process considers whether the medical use of the apps is sufficient for users' self-management. This study aims to contribute to the technology development process of diabetes apps by exploring individual perspectives on desired features and content of diabetes apps among people with diabetes. The vision assessment conducted is a first step toward creating a shared vision among all relevant stakeholders. To ensure adequate research and development processes for diabetes apps in the future, guiding visions from all relevant stakeholders are required. In a qualitative study, 24 semistructured interviews with patients with type 1 diabetes were conducted, among whom 10 (42%) were currently using an app. To clarify the perceptions of people with diabetes regarding the functions and content of diabetes apps, a vision assessment was conducted. People with diabetes have concrete ideas of features and content in apps to improve their QoL and allow them to live as comfortably as possible, such as informative predictions through artificial intelligence, improvements in signal loss and value delay through smartwatches, improved communication and information-sharing capabilities, reliable information sources, and user-friendly and discreet messaging options through smartwatches. In addition, according to people with diabetes, future apps should show improved sensors and app connectivity to avoid incorrect values being displayed. They also wish for an explicit indication that displayed values are delayed. In addition, personalized information was found to be lacking in apps. People with type 1 diabetes want future apps to improve their self-management and QoL and reduce stigma. Desired key features include personalized artificial intelligence predictions of blood glucose levels, improved communication and information sharing through chat and forum options, comprehensive information resources, and smartwatch alerts. A vision assessment is the first step in creating a shared vision among stakeholders to responsibly guide the development of diabetes apps. Relevant stakeholders include patient organizations, health care professionals, insurers, policy makers, device manufacturers, app developers, researchers, medical ethicists, and data security experts. After the research and development process, new apps must be launched while considering regulations regarding data security, liability, and reimbursement.

Robust Hybrid Beamforming for Outage-Constrained Multigroup Multicast mmWave Transmission With Phase Shifter Impairments

This article investigates robust hybrid beamforming design for outage-constrained multigroup multicast millimeter-wave (mmWave) transmission. The phase shifter impairments incorporated in the analog beamformer can impose negative damage on the Quality of Service (QoS) of users. To address this imperfect hardware problem, phase shifter impairments are modeled, and robust hybrid beamforming is formulated to maximize the worst-case signal-to-interference–plus-noise ratio (SINR). The digital beamformer and analog beamformer are jointly optimized based on an alternating optimization (AO) approach, where both the outage probability of users and the average transmit power at the base station (BS) are derived into closed-form expressions in each iteration. Moreover, the semidefinite programming (SDP) approach is resorted to handling the hybrid beamforming design. Based on the penalty and the successive convex approximation (SCA) approaches, we further propose a penalty-SCA-SDP-AO (PSSA) algorithm to address the constant-modulus constraint caused by phase shifters and the rank-one constraint introduced by the semidefinite form. Simulation results show that compared to the conventional nonrobust design, our robust hybrid beamforming design generally improves 40% nonoutage performance at least.

Patch-Based Image Learned Codec using Overlapping

End-to-end learned image and video codecs, based on auto-encoder architecture, adapt naturally to image resolution, thanks to their convolutional aspect. However, while coding high resolution images, these codecs face hardware problems such as memory saturation. This paper proposes a patch-based image coding solution based on an end-to-end learned model, which aims to remedy to the hardware limitation while maintaining the same quality as full resolution image coding. Our method consists in coding overlapping patches of the image and reconstructing them into a decoded image using a weighting function. This approach manages to be on par with the performance of full resolution image coding using an endto-end learned model, and even slightly outperforms it, while being adaptable to different memory sizes. Moreover, this work undertakes a full study on the effect of the patch size on this solution’s performance, and consequently determines the best patch resolution in terms of coding time and coding efficiency. Finally, the method introduced in this work is also compatible with any learned codec based on a conv/deconvolutional autoencoder architecture without having to retrain the model.

Massive multiple-input multiple-output channel estimation under hardware and channel impairments

Hardware problems are the most detrimental issues to channel estimates in wireless communication systems. Because of the enormous number of antennas at the base station (BS) in cellular massive multiple-input multiple-output (MIMO) systems and because one radio frequency (RF) chain per antenna is required, hardware impairments in such systems will be quite severe. Many research publications have used a quality-cost tradeoff to adjust for RF unit hardware issues. In this study, we have taken a different approach by reducing the error floor caused by impairments in the predicted channels. Here are two steps to remedy the problem. In phase 1, a single active user channel in a single cell was calculated statistically rather than parametrically. In phase 2, a convex optimization approach was used to regularize the estimated channel in phase 1 to reduce error and provide a robust channel estimate. The results of our proposed procedure are measured by the normalized minimum mean squared error (NMSE) versus a range from the effective signal-to-noise ratio, and it shows a significant reduction (nearly one order of magnitude) in the error floor as compared with the conventional one, especially at high signal-to-noise ratio (SNR) in the range of (20 dB-30 dB). Simulation results were extracted in MATLAB R2020a.

Reconstruction after resection of C2 vertebral tumors: A comparative study of 3D-printed vertebral body versus titanium mesh.

Surgical resection of C2 vertebral tumors is challenging owing to the complex anatomy of C2 vertebrae and the challenges to surgical exposure. Various surgical approaches are available, but some are associated with excessively high risks of complications. An additional challenge is reconstruction of the upper cervical spine following surgery. In the last decade, additive-manufacturing personalized artificial vertebral bodies (AVBs) have been introduced for the repair of large, irregular bony defects; however, their use and efficacy in upper cervical surgery have not been well addressed. Therefore, in this study, we compared instrumented fixation status between patients who underwent conventional titanium mesh reconstruction and those who underwent the same resection but with personalized AVBs. We performed a retrospective comparative study and recruited a single-institution cohort of patients with C2 vertebral tumors. Clinical data and imaging findings were reviewed. Through data processing and comparative analysis, we described and discussed the feasibility and safety of surgical resection and the outcomes of hardware implants. The primary outcome of this study was instrumented fixation status. The 31 recruited patients were divided into two groups. There were 13 patients in group A who underwent conventional titanium mesh reconstruction and 18 group B patients who underwent personalized AVBs. All patients underwent staged posterior and anterior surgical procedures. In the cohort, 9.7% achieved total en bloc resection of the tumor, while gross total resection was achieved in the remaining 90.3%. The perioperative complication and mortality rates were 45.2% and 6.5%, respectively. The occurrence of perioperative complications was related to the choice of anterior approach (p < 0.05). Group A had a higher complication rate than group B (p < 0.05). Four patients (4/13, 30.8%) developed hardware problems during the follow-up period; however, this rate was marginally higher than that of group B (1/18, 5.6%). Total resection of C2 vertebral tumors was associated with a high risk of perioperative complications. The staged posterior and retropharyngeal approaches are better surgical strategies for C2 tumors. Personalized AVBs can provide a reliable reconstruction outcome, yet minor pitfalls remain that call for further modification.
