The dynamic nature of modern network settings presents challenges for traditional base stations, leading to inefficient resource utilisation. These issues are exacerbated by the unpredictability of network scenarios, such as unexpected hardware problems or sudden increases in user demand. More adaptive and intelligent systems that can handle these issues are becoming increasingly critical and essential. Open-RAN is an intelligent and adaptable mobile network architecture featuring learning-based capabilities and a software layer for adaptation that can incorporate AI and ML to optimise communication networks and improve resource efficiency. Hence, this article aims to systematically review intelligence for Open-RAN through the adoption of the RAN Intelligent Controller (RIC). This comprehensive review also includes (1) real-world use cases for various industries, (2) the potential use cases for various intelligent models in terms of 5G core, RAN and air interface, (3) the advantages and challenges of AI incorporation within Open-RAN, and (4) the societal, environmental and economic impact of Open-RAN intelligence. This article outlines the significance of intelligence in the context of Open-RAN and highlights potential use cases, examining their impact and presenting challenges for further exploration by researchers in the field.

Motivation: Traditional methods for detecting large-scale mitochondrial DNA (mtDNA) deletions (LSMDs) in cells present challenges, i.e. a priori information, high DNA inputs, poor sensitivity and are not always quantitative. Mitigation can be achieved through high throughput DNA sequencing using e.g. Illumina and Oxford Nanopore Technologies (ONT), in combination with LSMD breakpoint identification and quantification using bioinformatic tools. Splice-aware RNA alignment tools increase the sensitivity for detecting LSMD breakpoints compared with DNA aligners. Long-read sequencing (LRS) also offers potential advantages over short read sequencing, e.g. greater read lengths and capturing variants on single reads. No existing pipelines capture the benefits of both a splice-aware alignment tool and LRS. Results: We developed NanoDel, a LRS pipeline, to sensitively and accurately detect cellular LSMDs. Using artificial datasets, NanoDel was more sensitive and accurate than other pipelines. In samples diagnosed with mitochondrial disease, it identified both known and previously uncharacterised (including mixtures) of LSMDs, without a priori information. LSMD breakpoints were found in mt-co1, mt-cyb, mt-nd6 and mt-nd5 genes. Analysis of selected LSMDs revealed proximity to repeat and putative G-quadruplex motifs, and occurrence in a range of healthy and pathological tissues, indicating potential for a shared vulnerability landscape in mtDNA, shaped by sequence motifs and structural constraints. NanoDel combined with one-amplicon, not two-amplicon, LR-PCR offers a robust strategy with clinical application for detecting LSMDs across a variety of cell/tissue samples, and it′s application across a broader range of samples, will yield new mechanistic insights into LSMD formation, and further our understanding of mtDNA instability. Availability and implementation: NanoDel is available at https://github.com/uopbioinformatics/NanoDel and raw read data are available through the NCBI Sequence Read Archive (SRA) under BioProject accession code PRJNA1369153 (https://www.ncbi.nlm.nih.gov/bioproject/1369153).

Objective.This article explores a new graphics processing unit (GPU)-based techniques for efficient image reconstruction in organ-targeted positron emission tomography (PET) scanners with planar detectors.Approach.GPU-based reconstruction is applied to the Radialis low-dose organ-targeted PET technology, developed to overcome the issues of high exposure and limited spatial resolution inherent in traditional whole-body PET/CT (Computed Tomography) scans. The Radialis planar detector technology is based on four-side tileable sensor modules that can be seamlessly combined into a sensing area of the needed size, optimizing the axial field-of-view for specific organs, and maximizing geometric sensitivity. The article explores the transition from central processing unit-based maximum likelihood expectation maximization algorithms to a GPU-based counterpart, demonstrating a tenfold overall speedup in image reconstruction with a hundredfold improvement in iteration speed.Main results.Through standardized PET performance tests and clinical image analysis, this work demonstrates that GPU-based image reconstruction maintains diagnostic image quality while significantly reducing reconstruction times. The application of this technology, particularly in breast imaging using the Radialis low-dose positron emission mammography, significantly reduces exam times thus improving patient comfort and throughput in clinical settings.Significance.This study represents an important advancement in the clinical workflow of PET imaging, providing insights into optimizing reconstruction algorithms to effectively leverage the parallel processing capabilities of GPUs.

The development of information and communication technologies brings numerous changes to everyday life, including learning and teaching. We live in a time when it is impossible to imagine performing certain activities without the use ofmodern technology and devices. The development of technology has also impacted the education system implemented in schools. Technology is a part of the process of modern education, with online teaching being an important segment. Online teaching is increasingly being implemented alongside traditional teaching methods or is completely replacing them. Therefore, it is important to examine the possibilities of implementing online teaching in our context. Through the use of modern technology, teaching becomes dynamic, and students become more active and motivated. This paper explores the assessment of the possibilities and organization of online teaching from the perspective of students. In cases where regular teaching cannot be carried out or as a supplement to regular teaching, there is a need for online teaching. The primary objective of this paper is to identify the possibility of implementing online teaching. The paper highlights that integrating new technologies into all aspects of the educational process contributes to more efficient education. We believe that the results obtained will greatly assist in organizing online teaching. Research results show that students are familiar with the terms of online teaching, and with the possession of digital devices, it is possible to implement online teaching synchronously, asynchronously, or through hybrid learning. The significance of feedback from teachers on homework assignments is of great importance in the teaching process, both in traditional and online learning. Through research, we have confirmed that with proper organization and engagement of all participants in the teaching process, online teaching can be equally effective as traditional classroom teaching. There is no preference among students for traditional teaching or online teaching; students would prefer certain content to be taught traditionally in the classroom and certain content via online platforms.

This paper presents the development of a coupled finite element - boundary element model of rolling noise from a resilient light rail wheel on several types of tracks. The vibro-acoustic model utilizes a 3D elastic solid representation for both wheel and rail which are excited by linearized Hertzian interface loads. Estimates of the radiated sound power, radiation efficiencies and wayside noise levels are obtained and then scaled using a parallel impedance framework and a roughness profile. Results are compared to recently measured vehicle passby noise and track decay rates at Sound Transit in Seattle Washington.

O presente estudo objetiva apresentar um breve apanhado do histórico e da produção dos Ateliês Superiores Técnico-Artísticos Estatais, Vkhutemas, inaugurados em 1920, na Rússia, com a intenção de ressaltar seu legado para o design, tratando também de outras contribuições de nomes relevantes do design social. Partindo da percepção de que pouco é abordado sobre a escola no ensino de design, que prioriza o estudo sobre instituições como Bauhaus e Ulm, mesmo que estas mesmas tenham sido influenciadas pela herança das Vkhutemas, buscou-se explorar informações que evidenciem a importância do acúmulo teórico e prático da escola para a formação de designers críticos, que visam uma atuação emancipada e emancipatória, com foco na sociedade e sua transformação radical.

To report the clinical and radiological outcomes of arthroscopic bone grafting and percutaneous K-wire fixation without radial styloidectomy in patients with scaphoid nonunion advanced collapse (SNAC).We retrospectively analyzed the records of 15 patients with SNAC who were treated with arthroscopic bone grafting and percutaneous K-wire fixation and subsequently followed up for a minimum of 1 year between November 2009 and March 2018. The clinical outcomes were evaluated by comparing the range of motion (ROM), grip strength, the modified Mayo Wrist Score, and visual analog scale (VAS) scores for pain, all of which were measured preoperatively and at the last follow-up. The radiologic outcomes were evaluated by comparing the scapholunate (SL) and radiolunate (RL) angles preoperatively and at the last follow-up.All 15 cases of nonunion were resolved. The average radiologic union time was 9.7 ± 1.2 weeks. The average VAS score increased from 5.7 ± 2.3 (range, 2 − 10) preoperatively to 1.3 ± 1.3 (range, 0 − 3) at the last follow-up (P < .05). The average modified Mayo wrist score increased from 58.3 ± 14.0 preoperatively to 80.0 ± 9.2 at the last follow-up (P < .05). The mean ROM of the wrist improved, but there was no statistical significance. At the last follow-up, the mean flexion and radial deviation on the affected side were significantly decreased, and the mean extension on the affected side was significantly improved compared to the normal side (P < .05). The mean preoperative SL and RL angles were 66 ± 11.9° and 7.2 ± 6.8°, respectively, and were decreased to 50.4 ± 7.5° and 6.4 ± 5.2°, respectively, at the last follow-up. The mean SL angle was significantly corrected (P = .01).Arthroscopic bone grafting and percutaneous Kerschner (K)-wire fixation without radial styloidectomy are considered to be very effective methods for correcting scaphoid deformities to treat SNAC stage I. However, caution may be needed during the surgery to prevent reductions in flexion and the radial deviation of the wrist.
