Integrated Sensing and Communications for V2I Networks: Dynamic Predictive Beamforming for Extended Vehicle Targets
Authors: Du Zhen , Liu Fan , Yuan Weijie , Masouros Christos , Zhang Zenghui , Xia Shuqiang , Caire Giuseppe
Published: March 2022

We investigate sensing-assisted beamforming for vehicle-to-infrastructure (V2I) communication by exploiting integrated sensing and communication (ISAC) functionalities at the roadside unit (RSU). The RSU deploys a massive multi-input-multi-output (mMIMO) array at mmWave. The pencil-sharp mMIMO beams and fine range-resolution implicate that the point-target assumption is impractical, as the vehicle’s geometry becomes essential. Therefore, the communication receiver (CR) may never lie in the beam, even when the vehicle is accurately tracked. To tackle this problem, we consider the extended target with two novel schemes. For the first scheme, the beamwidth is adjusted in real-time to cover the entire vehicle, followed by an extended Kalman filter to predict and track the position of CR according to resolved scatterers. An upgraded scheme is proposed by splitting each transmission block into two stages. The first stage is exploited for ISAC with a wide beam. Based on the sensed results at the first stage, the second stage is dedicated to communication with a pencil-sharp beam, yielding significant communication improvements. We reveal the inherent tradeoff between the two stages in terms of their durations, and develop an optimal allocation strategy that maximizes the average achievable rate. Finally, simulations verify the superiorities of proposed schemes over state-of-the-art methods.

Published: March 2022

Objective: Aiming to reduce distributed denial-of-service (DDoS) attacks by alerting the consciences of Internet users, this paper evaluates the efectiveness of four warning banners displayed as online ads (deterrent—control, social, informative, and reorienting) and the contents of their two linked landing pages.Methods We implement a 4×2 quasi-experimental design on a self-selected sample of Internet users to measure the engagement generated by the ads and the pages. Engagement is measured on the ads as the ratio of clicks to impressions and on the pages as percentage of page scrolled, average session duration, video interaction rate, and URLs click rate.Results: Social ads generate signifcantly more engagement than the rest with low to medium efect sizes. Data reveal no diferences in engagement between both landing page designs.Conclusions: Social messages may be a better alternative for engaging with potential cyber ofenders than the traditional deterrent messages.

TraSw: Tracklet-Switch Adversarial Attacks against Multi-Object Tracking
Authors: Lin Delv , Chen Qi , Zhou Chengyu , He Kun
Published: March 2022

Multi-Object Tracking (MOT) has achieved aggres?sive progress and derives many excellent deep learning models. However, the robustness of the trackers is rarely studied, and it is challenging to attack the MOT system since its mature association algorithms are designed to be robust against errors during the tracking. In this work, we analyze the vulnerability of popular pedestrian MOT trackers and propose a novel adversarial attack method called Tracklist-Switch (TraSw) against the complete tracking pipeline of MOT. TraSw can fool the advanced deep trackers (i.e., FairMOT and ByteTrack) to fail to track the targets in the subsequent frames by attacking very few frames. Experiments on the MOT-Challenge datasets (i.e., 2DMOT15, MOT17, and MOT20) show that TraSw can achieve an extraordinarily high success rate of over 95% by attacking only four frames on average. To our knowledge, this is the first work on the adversarial attack against pedestrian MOT trackers.
Elevated PPP2R3A expression distinguishes basal-like human breast cancer.
Authors: Mamoor Shahan
Published: March 2022

Patients diagnosed with basal-like breast cancer face a more aggressive disease course and more dismal prognosis than patients diagnosed with luminal A and luminal B breast cancer molecular subtypes (1-4). We mined published microarray data (5, 6) to understand in an unbiased fashion the most distinguishing transcriptional features of tumors from patients with basal or basal-like subtype breast cancer. We observed transcriptome-wide differential expression of protein phosphatase 2 regulatory subunit B''alpha, PPP2R3A, when comparing tumors of patients with basal-like breast cancer with that of other PAM50 molecular subtypes. PPP2R3A mRNA was present at significantly higher quantities in the tumors of patients with basal-like breast cancer. Analysis of patient survival data revealed that PPP2R3A primary tumor expression was correlated with distant metastasis-free survival in HER2+ subtype breast cancer. Elevated PPP2R3A expression appears to distinguish basal-like human breast cancer from the other molecular subtypes.

Published: March 2022

This paper presents a collaborative target tracking application with multiple agents and a formulation of an agent-formation problem with desired inter-agent distances and specified bounds. We propose a barrier Lyapunov function?based distributed control law to preserve the formation for target-tracking and assess its stability using a kinematic model. Numerical results with this model are presented to demonstrate the advantages of the proposed control over a quadratic Lyapunov function-based control. A concluding evaluation using experimental ROS simulations is presented to illustrate the applicability of the proposed control approach to a multi-rotor system and a target executing straight line and circular motion.

Published: March 2022

Relationship quality and emotional experience are both important constructs in learning environments but the question of how they are linked requires more attention in empirical research. We hypothesized reciprocal associations between student-teacher relationship quality (i.e., interpersonal closeness) and students' emotions in the classroom (i.e., enjoyment, pride, anxiety, anger, boredom, and shame). Data from a two-wave longitudinal study with annual assessments in grade 10 (Time 1) and 11 (Time 2) were used to test this hypothesis (N = 535; mean age at Time 1: 16.7 years, SD = 0.6). Student-perceived relationship quality and students’ emotions were assessed in the academic domains of mathematics, German, English, and French. In line with our hypothesis, cross-lagged panel models showed reciprocal associations: Higher relationship quality was associated with stronger positive emotions and weaker negative emotions over time. In turn, lower negative emotions and higher positive emotions were associated with higher relationship quality. The association between initial emotions and student-teacher relationship quality one year later was stronger than the reverse association. Further, the links between relationship quality and emotions were largely equivalent across school domains but differed in strength across emotions. Implications for future research and educational practice are discussed.

Balancing MultiWavelets (about balancing order and other discrete-time properties of multiwavelets)
Authors: Lebrun Jerome
Published: March 2022

Multiwavelets are a generalization of wavelets where one allows the multiresolution analysis to be generated by a finite number of scaling functions instead of only one. This approach allows to overcome some limitations in the design of filter banks preventing the construction of non-trivial, orthonormal bases from compactly supported, symmetric wavelets.However, in order to obtain multifilter banks that are appropriate for processing scalar signals, new conditions, coined ''balancing'', have to be imposed in the design of multiwavelets. A thorough study of the discrete-time properties of multifilter banks shows that the balancing conditions are closely related to the important issue of the preservation of discrete-time polynomial signals. Balancing is then proved to be equivalent to a very natural factorization of the lowpass synthesis refinement mask and to some Strang-Fix conditions on a time-varying scalar subdivision operator. Connections are also made with the usual properties of the associated multiresolution analysis (approximation power, moments of the scaling functions, superfunction theory). MultiCoiflets, the natural generalization of Coiflets, come out as a special case of balanced multiwavelets.With the help of computational algebraic geometry, in particular Groebner bases methods, the design of several families of orthonormal balanced multiwavelets and multiCoiflets with compact support, symmetries and minimal-length multifilters is detailed. A new concept of discrete-time balanced smoothness is introduced to measure the influence of ergodic properties (zeros at preperiodic points of invariant cycles) on the smoothness of the iterated multifilter bank. Finally, the description of a significance tree image coder based on balanced multiwavelets concludes this thesis dissertation.

Introduction: Diabetes is on the rise worldwide and India has more number of diabetics with more than 60 million people diagnosed to suffer from the disease in 2013. Approximately 20% to 30% of all diabetics will develop evidence of nephropathy, although a higher percentage of type 1 patients progress to end stage renal disease. Diabetic nephropathy (DN) is characterised by macro albuminuria and abnormal renal function as represented by a reduction in glomerular filtration and rise in serum urea and creatinine. Aim & Objectives: The aim of this study was to study the relationship between blood levels of urea and creatinine with blood glucose levels in diabetic and non-diabetic subjects for their utility in diagnosis of diabetic nephropathy and their comparison with glycemic status. Material and Methods: Diabetic and non-diabetic subjects; 100 in each group; attending out- patient department during 15 May to 15 September 2015 were studied. Patients with known kidney disease were excluded. Blood samples were analysed for blood sugar (glucose), serum urea and creatinine to determine presence of kidney disease and hyperglycemia on basis of reference laboratory standards in the institute. Results: Out of 100 diabetes samples, 18 had high urea level whereas 15 had increased creatinine level. In control group of 100 sample, there was no one with high urea value and 2 had high creatinine level. There was statistically significant increase in urea level with increased blood sugar level (p<0.05, 95%CI). Conclusion: Serum urea and creatinine are useful, simple biomarkers as predictor and prognostic tests of renal failure in diabetic patients, despite some limitations.

Aeromedical Evacuation (MEDEVAC) of critically ill patient is a risky business. The hostile and unsavory environment of the aircraft subjects not only the patient and the Critical care air transport team (CCATT) but also the monitoring equipment carried to tremendous amount of stress and strain. The monitoring standards required in such alien environment cannot be compromised and in-fact is required a step higher than required in the ground. However most of the equipments are not designed to compensate for such austere conditions. Hence it becomes imperative to understand the nuances of this alien environment on the monitoring equipments which are exposed to changes in pressure, temperature, gravitational forces, noise,vibrations etc.

Poststroke fatigue (PSF) is a debilitating but often neglected consequence of stroke. This cross-sectional study evaluated the prevalence of PSF among one hundred stroke survivors receiving physiotherapy in North-east Nigeria. Demographic and clinical data were obtained while PSF was assessed with the 9-item Fatigue Severity Scale. Descriptive and Chi-square statistics were used to respectively summarize the data, and explore the differences in prevalence of PSF among the age and gender sub-groups. The majority of the participants were males (66%). Mean age and mean post-stroke duration was 55.3 (SD 13.9 years) and 12.6 months (SD 19.3 months) respectively. Eighty-two (82%) participants were found to have PSF. Prevalence of PSF did not significantly differ based on the age (P= 0.42) and gender (P= 0.63) of the participants. The observed high prevalence of PSF emphasizes the urgent need for increased awareness and detection of PSF as well as effective PSF management.

Cataract is characterized partial or complete loss of transparency of the lens that leads to loss of vision. Globally, cataract associated blindness is a major cause of morbidity in developing countries. The cataractogenesis is affected by a number of factors with redox imbalance at the top of list. This imbalance results either from an increased generation of free radicals and/or decreased production of antioxidants. The end products of lipid peroxidation are both mutagenic and carcinogenic. One such product, malondialdehyde (MDA) reacts with deoxyadenosine and deoxyguanosine in DNA, to form DNA adducts. Its role in cataractogenesis is due to its cross linking ability. The present study analyzed the role of MDA in the development of senile cataract. Its level was measured in 75 randomly selected senile cataract patients of different age groups and matched against suitable controls. The study found statistically significant increased levels of MDA in cataract patients but not in controls, indicating an oxidative stress. The present study concluded that increased levels of MDA increased the susceptibility to cataractogenesis.

Background- Team Objective Structured Bedside Assessment (TOSBA) is a ward based, directly observed group assessment tool. The present study was undertaken to assess the impact of TOSBA in improving clinical competence of postgraduate students and also to assess student and staff perceptions of this method of formative assessment. Material and Methods- To study the impact of TOSBA, the students were divided into 2 groups. Group A was taken as ‘study group’ and Group B as ‘control group’, both groups comprising of three students each. Consecutive students in each group were given ten minutes for performing one of three different standardized clinical tasks. The students were directly observed performing the tasks and were graded on their performance in each group. Group A students were provided with educational feedback by the examiner at the end of the session, whereas Group B did not receive any feedback, but were shown their grades at the end of each TOSBA session. A pre-test in first session and post –test at the end of total 3 TOSBA sessions, was conducted on both groups. Feedback was taken from both, the students and staff members, regarding their view about this method of assessment in the form of a questionnaire, on various points on a Likert scale. Results and conclusion- The mean score for post-test in the study group was (7.51 ± 0.67) whereas the mean post-test score in the control group, which was not subjected to feedback, was (6. 34 ± 0.12), for which P value of <0.0001 was obtained, which was statistically highly significant. The present study showed that TOSBA, as a formative method of assessment, improves all the three major domains of the learner and reinforces team communication skills.

Objective: To evaluate the role of ethanolic extract and methanolic fraction of the roots of Delphinium denudatum Wall. in morphine dependence. Methods: Wistar albino rats were made moderately and severely morphine dependent by administering morphine sulphate in a dose of 10 mg /kg (i.p.) for 4 days and by increasing doses of 10 -100 mg/kg (i.p.) for 7 days twice daily, respectively. The signs of spontaneous abstinence syndrome in both studies were recorded 12 hours after the last dose of morphine for 30 minutes and quantified by the 'counted' and 'checked' signs. Ethanolic extract (EEDD) and methanolic fraction (MFDD) of Delphinium denudatum was administered p.o. in different regimen: (a) 300 mg/kg (p.o.) of ethanolic extract or 200 mg/kg (p.o.) of methanolic fraction along with morphine twice daily for 4 days in moderately and 7 days in severely induced morphine dependence group, (b) Single dose of ethanolic extract 600 mg/kg (p.o.) or methanolic fraction of 400 mg/kg (p.o.) 10 h after the last dose of morphine in both moderately and severely induced morphine dependence rats. Result: Administration of EEDD and MFDD orally in both morphine dependent groups caused significant reduction in scores of counted and checked signs of morphine abstinence syndrome as compared to morphine control group. The reduction was observed more in regimen 'b' as compared to regimen 'a'. Conclusion: EEDD and MFDD of Delphinium denudatum root significantly reduced the mean scores of various 'counted signs' and 'checked signs’ of morphine withdrawal syndrome and could thus be proved to be an alternative remedy in morphine de-addiction.

Published: March 2022

Background: Despite the rise in risk factor burden for coronary artery disease (CAD) and heart failure among Africans, post myocardial infarction heart failure is rarely reported. Aim and Objectives: We aim to use major electrocardiographic indices suggesting old myocardial infarction and echocardiographic evidence of relative wall motion abnormalities to determine the possible contribution of CAD to the aetiology of heart failure among Africans. Study Design: Prospective observational study. Setting: Goshen Heart Clinic, Osogbo, Nigeria. Methods: 129 consecutive subjects with heart failure diagnosed using the Framinghams’s criteria were included in this study seen at the Goshen Heart Clinic, Osogbo, Nigeria. They had ECG and echocardiography among other investigations. Old Myocardial infarction (MI) on ECG was assessed using standardized criteria using the Third Universal definition of MI while relative wall motion abnormalities were assessed during echocardiography. Statistics: Statistical Package for Social Sciences 17.0 was used for statistical analysis. Results: The mean age of the study participants was 62.1 ± 13.7 years. There were 57 females (44.2%). Possible CAD was identified in 18 (13.95%) of study participants and they were more likely to be significantly older, had a lower ejection fraction , a higher fasting blood sugar and a higher left ventricular chamber walls dimensions compared to those without possible CAD. Conclusion: CAD may be a significant contributor to the aetiology of heart failure subjects among Africans and it is important to look for possible significant coronary atherosclerosis and treat appropriately even among Africans with heart failure.

Since Joubert et al. first described a familial syndrome comprised of agenesis of the cerebellar vermis, episodic hyperpnea and apnea, abnormal eye movements, ataxia, and retardation associated with genesis of the cerebellar vermis, several additional cases have been reported from various parts of the world. Other abnormalities have been associated with Joubert syndrome, such as an occipital meningocele, polydactyly, facial asymmetry, and chorioretinal coloboma. We report the case of a 4-year-old male, referred to our rehabilitation department with a history of hypotonia and delayed psychomotor development. Cerebral magnetic resonance imaging (MRI) led to the clinical diagnosis of Joubert Syndrome.

Hydatid disease (HD) is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Herein we report a new case of primary retroperitoneal hydatid cyst diagnosed with abdominal pain and palpable large mobile mass on the right side of abdomen.

Background: Upper respiratory tract infections (URTIs) occur most commonly among children and considered as a major cause of mild morbidity. Aims and objectives: This study was conducted to assess parental knowledge and to identify their attitudes and practices related to antibiotic use in the treatment of childhood upper respiratory tract infections (URTIs). Study design: A cross-sectional study. Setting: The study was conducted during the period of January-March 2014 in Taif City, Saudi Arabia. Methods: Adult (> 18 year) Saudi people residing the city were included. Convenience method of sampling was adopted. Data was collected by mean of a structured questionnaire. Statistics: Data was processed using the Statistical Package for Social Science (SPPS). Logistic regression analysis was performed. P value< 0.05 was considered statistically significant. Results: A total of 400 participants was included, of them 236 (59%) were males. Overall, 124 (31.0%) of all interviewed parents had satisfactory knowledge on antibiotic use. Multivariate analysis showed that higher education was found to be the only predictor of satisfactory knowledge, [OR 2.5 CL (1.7- 4.5), (P= 0.026)]. Of all the parents 206 (51.5%) often give the child antibiotic based on a pharmacist recommendation and 193 (48.3%) of them reuse the antibiotic previously given for the same symptoms. Conclusion: Parents in the study area had poor knowledge on antibiotic use, which is significantly dependent on parents' level of education. In addition, some misconceptions on parents attitudes and practices related to the use antibiotics for the treatment of URTIs among children were identified.

Objective: Kaposi sarcoma (KS) is the most common tumour among AIDS patients and is considered as an AIDS defining illness. However, the introduction of HAART has led to a decline in the incidence of the disease among these patients. The objective of this study is to review the clinical presentation, treatment and outcome of HIV associated KS in a tertiary health facility in Nigeria. Methods: Records of all patients that were managed with HIV associated KS from January 2012 to December 2014 at Aminu Kano Teaching Hospital were reviewed and data obtained was analysed using a computer statistical software. Results: During the period under review, 3705 patients were recruited in the antiretroviral treatment (ART) clinic out of which 24 were found to have HIV associated KS giving a period prevalence of 0.65%. The male to female ratio was 2.4:1. The mean age of the patients was 39.46 (±8.75) years. Six cases (25%) were diagnosed to have HIV as a result of KS. The remaining 75% were all on 1st line ARVs. Nine patients (37.5%) had treatment for Tuberculosis before they were diagnosed with KS. Based on the ACTG classification, 58.3% were poor risk group. Treatments given to the patients include HAART for 2 patients and 4 patients (16.7%) absconded. The remaining 18 patients had chemotherapy in the form of combination of intravenous Adriamycin, Bleomycin and Vincristine (ABV) with variable outcomes. Five patients failed ABV and had Paclitaxel given. At the end of the chemotherapy, 14 patients (58.3%) were in remission with 5 (20.8%) mortalities. There is no statistically significant difference between CD4 count before and after chemotherapy (P>0.05) Conclusions: Majority of our patients are classified poor risk. Paclitaxel can be used as second line treatment. Treatment of KS does not improve CD4 count in patients with HIV. There is need to clinically identify patients with KS early in ART centre in order to improve outcome.

Objective: The purpose of the present study was to identify the gaps in the management of Wilms’ tumor which resulted in an inferior outcome and to see if there is any improvement since the last study and to come up with recommendations to improve the outcome of Wilms’ tumor. Patients and Methods: This was a retrospective hospital based study at Urology Institute of Kilimanjaro Christian Medical Centre. Patients operated for Wilms’ tumor between January 2006 and December 2013 were identified and the medical records of the 46 patients eligible for the study retrieved. The relevant information was entered into the prepared data collection format. The data was cleaned, summarized and analysed using SPSS version 17. Results: Patients with Wilms’ tumor presented late to KCMC. There was no undue delay in reaching at diagnosis. From the 46 total number of patients in this study 20 (43.5%) of patients received neoadjuvant chemotherapy while 26 (56.5%) had an upfront nephrectomy. The one year recurrence free survival was 32.6% with a high rate of lost to follow up (41.3%), perioperative mortality of (10.8%), and recurrence rate of (26.8%). Conclusion: There was no improvement in the outcome of WT at KCMC compared to the last report 8 years back. Patients still present late to health institutions, there is high rate of lost to follow up and the prognosis of Wilm’s tumor in this part of Africa is still dismal.

The article analyzes the current state of the population’s beef supply. A low proportion of beef breeds of cattle in the formation of beef food resources was revealed. It is shown that the economic indicators of animals in the cultivation and fattening of beef cattle breeds are significantly higher than similar indicators for dairy cattle breeds. The concentration of cattle of meat breeds in organizations with small production sizes was noted. The absence of dependence of the efficiency of meat production on the size of production and the combination of directions of agricultural production, as well as on the depth of specialization in meat production, was revealed. Prospects for the development of beef cattle breeding are associated with the implementation of internal reserves, the development of consumer cooperation of small forms of management.

The effective development of the regional agro-industrial complex largely depends on the state management of the agrarian sector. The regulation of agro-industrial production does not have a clear delineation of the administrative functions of the authorities at various levels. Therefore, it is important to develop a unified approach to the management of the agro-industrial complex of the region, since at present there is a divergence of both production and economic interests of economic entities of the agro-industrial complex, as well as a violation of intersectoral balances. The purpose of the work is to develop a new form of management of the regional agro-industrial complex. The article presents the structure of management of the agro-industrial complex at the federal and regional levels. The reasons for the decline in the manageability of the industry are identified. The necessity of developing new approaches to the management of the regional agro-industrial complex has been substantiated. The work provides a detailed analysis of the main approaches to the management of the agro-industrial complex in a historical sequence, starting from the end of the 19th and to the beginning of the 21st centuries, which made it possible to summarize the strengths and weaknesses of the studied forms of management. The article substantiates a new form of management of the agro-industrial complex of the region, which has incorporated the main strengths of the previously existing forms of agro-industrial interaction. The proposed approach is based on the interaction of all spheres: production, processing, education, science, where the state should act as a driver of development.
