Dynamic Hierarchical Cache Management for Cloud RAN and Multi- Access Edge Computing in 5G Networks

Cloud Radio Access Networks (CRAN) and Multi-Access Edge Computing (MEC) are two of the many emerging technologies that are proposed for 5G mobile networks. CRAN provides scalability, flexibility, and better resource utilization to support the dramatic increase of Internet of Things (IoT) and mobile devices. MEC aims to provide low latency, high bandwidth and real- time access to radio networks. Cloud architecture is built on top of traditional Radio Access Networks (RAN) to bring the idea of CRAN and in MEC, cloud computing services are brought near users to improve the user’s experiences. A cache is added in both CRAN and MEC architectures to speed up the mobile network services. This research focuses on cache management of CRAN and MEC because there is a necessity to manage and utilize this limited cache resource efficiently. First, a new cache management algorithm, H-EXD-AHP (Hierarchical Exponential Decay and Analytical Hierarchy Process), is proposed to improve the existing EXD-AHP algorithm. Next, this paper designs three dynamic cache management algorithms and they are implemented on the proposed algorithm: H-EXD-AHP and an existing algorithm: H-PBPS (Hierarchical Probability Based Popularity Scoring). In these proposed designs, cache sizes of the different Service Level Agreement (SLA) users are adjusted dynamically to meet the guaranteed cache hit rate set for their corresponding SLA users. The minimum guarantee of cache hit rate is for our setting. Net neutrality, prioritized treatment will be in common practice. Finally, performance evaluation results show that these designs achieve the guaranteed cache hit rate for differentiated users according to their SLA

Seroprevalence of Hepatitis B infection among pregnant women in South India

Background: Vertical transmission of infection from mother to infants is a very important route of transmission of hepatitis B virus. Hepatitis B virus infection in pregnant women usually goes undetected. The hepatitis B surface antigen in serum is the first seromarker to indicate active HBV infection. This study was done to determine the seroprevalence of HBsAg in healthy asymptomatic antenatal women.Methods: It was a hospital based study over a period of two years. A total of 1282 antenatal patients were tested for hepatitis B surface antigen.Results: The prevalence rate of HBsAg was found to be 1.01 %( 13 positive out of 1282 cases). Highest prevalence was in age group 26-30(46%) followed by age group 31-35(30.8%) followed by age group 20-25 yrs (23.1%).Conclusions: Screening of all pregnant women for HBV irrespective of risk factors will reduce the prevalence and risks of HBV infection

Double trouble-unveiling the hidden pain: bilateral paediatric parsonage-turner syndrome: an unprecedented encounter

Parsonage-turner syndrome (PTS), also known as idiopathic brachial neuritis, is a rare disorder characterized by sudden-onset severe shoulder pain followed by weakness and atrophy of the shoulder and arm muscles. This case report presents the clinical scenario of an 11-year-old girl diagnosed with PTS, highlighting the unique challenges and considerations in the paediatric population. In our case, a 11-year-old girl presented with sudden-onset severe bilateral shoulder pain, followed by weakness and atrophy of the shoulder and upper arm muscles. The clinical examination revealed muscle wasting and limited range of motion. The diagnosis of PTS was confirmed through MRI and electromyography (EMG) showing denervation in the affected shoulder muscles. Patient was managed with symptomatic supportive treatment in the form of analgesics and physical therapy. Patient is on the road to recovery and on regular follow up. We concluded that prompt recognition and appropriate management of PTS are crucial to optimize outcomes and prevent long-term disability, particularly in the paediatric population

Anomalous common peroneal nerve supplying the gluteus maximus muscle with high division of sciatic nerve

On dissection of a 60-year-old adult male cadaver, a high division of the sciatic nerve was observed on the right side along with an accessory slip of the piriformis. In this case, the common peroneal nerve pierced through and the tibial nerve passed below the accessory slip of the piriformis. Additionally, there was an unusual finding in which the common peroneal nerve was found to innervate the gluteus maximus. This finding is of academic interest and clinical significance as this variation may contribute to clinical conditions such as piriformis syndrome and foot drop with injury to the gluteal region.Keywords: Sciatica, Common peroneal nerve, Gluteus maximus, Inferior gluteal nerve, variation

Interaction Visual Transformer for Egocentric Action Anticipation

Human-object interaction is one of the most important visual cues that has not been explored for egocentric action anticipation. We propose a novel Transformer variant to model interactions by computing the change in the appearance of objects and human hands due to the execution of the actions and use those changes to refine the video representation. Specifically, we model interactions between hands and objects using Spatial Cross-Attention (SCA) and further infuse contextual information using Trajectory Cross-Attention to obtain environment-refined interaction tokens. Using these tokens, we construct an interaction-centric video representation for action anticipation. We term our model InAViT which achieves state-of-the-art action anticipation performance on large-scale egocentric datasets EPICKTICHENS100 (EK100) and EGTEA Gaze+. InAViT outperforms other visual transformer-based methods including object-centric video representation. On the EK100 evaluation server, InAViT is the top-performing method on the public leaderboard (at the time of submission) where it outperforms the second-best model by 3.3% on mean-top5 recall

Evaluation of histopathology of cervix in women with unhealthy cervix

Background: Carcinoma of cervix is the third most common cancer in women worldwide and most common female cancer in India. Most cervical cancers can be detected at pre-invasive state with an adequate screening and treated, preventing overt progression to invasive cancer and hence decreasing morbidity and mortality. This study was conducted to evaluate the histopathological diagnosis of cervix biopsy in unhealthy cervix and to determine the incidence of the various precancerous and cancerous lesions.Methods: It was a prospective study in the department of Obstetrics and Gynecology in a tertiary care hospital over a period of two years. 802 women with unhealthy cervix were included in the study. Punch biopsy was taken from the cervix and sent for histopathological examination.Results: Total of 802 women were included in the study. They were in the age group of 26-75years. 53.4% were in the age group of 40-49 years followed by 20% in the age group of 30-39 years. The most common finding was chronic cervicitis in 89.4% followed by CIN I in 4.1%, CIN II in 0.9% of patients, squamous cell carcinoma in 2.1% and endocervical carcinoma in 0.4%.Conclusions: Cancer cervix is an ideal malignancy for screening, can be detected early and the premalignant lesion can be treated to prevent the progress to invasive disease. Hence all women with unhealthy cervix should be subjected to punch biopsy to detect early cases of cancer & carcinoma in situ

Clinicopathological analysis of cervical polyps

Background: Cervical polyps are the commonest cervical lesions and occur in about 2-5% of women. It is common practice to remove these polyps whenever they are identified and the main reason for this is the concern over the potential for malignant transformation. This study was done to analyse the spectrum of histopathological diagnosis in cases of cervical polyps and to identify focus of malignancy if present. This would help us to improve further management of cases of symptomatic and asymptomatic cervical polypsMethods: This study was conducted in the department of Obstetrics and Gynecology in a tertiary care teaching hospital over a period of two years. Women with a polypoidal growth from the cervix visualized on per speculum examination were included in the study. Polypectomy was done and the specimen sent for histopathological examination and the data analysed.Results: Total of 107 women was included in the study. Most of the women (47.7%) were in the age group 40-49 years. Endocervical mucous polyp was found to be the most common lesion (50.5%) followed by benign endometrial polyp (21.5%), and leiomyomatous polyp in 13.1%. There were no foci of malignancy identified in any of these polyps.Conclusions: As the incidence of malignancy in endocervical polyp is very low, it is suggested that in cases of asymptomatic polyps, there is a role for expectant management with no intervention and these patients can be followed up leading to significant savings in health resources
