Overview of Tensor-Based Cooperative MIMO Communication Systems—Part 1: Tensor Modeling

Due to increasingly strong and varied performance requirements, cooperative wireless communication systems today occupy a prominent place in both academic research and industrial development. The technological and economic challenges for future sixth-generation (6G) wireless systems are considerable, with the objectives of improving coverage, data rate, latency, reliability, mobile connectivity and energy efficiency. Over the past decade, new technologies have emerged, such as massive multiple-input multiple-output (MIMO) relay systems, intelligent reflecting surfaces (IRS), unmanned aerial vehicular (UAV)-assisted communications, dual-polarized (DP) antenna arrays, three dimensional (3D) polarized channel modeling, and millimeter-wave (mmW) communication. The objective of this paper is to provide an overview of tensor-based MIMO cooperative communication systems. Indeed, during the last two decades, tensors have been the subject of many applications in signal processing, especially for digital communications, and more broadly for big data processing. After a brief reminder of basic tensor operations and decompositions, we present the main characteristics allowing to classify cooperative systems, illustrated by means of different architectures. A review of main codings used for cooperative systems is provided before a didactic and comprehensive presentation of two-hop systems, highlighting different tensor models. In a companion paper currently in preparation, we will show how these tensor models can be exploited to develop semi-blind receivers to jointly estimate transmitted information symbols and communication channels.

DETECTION OF FECAL COLIFORM BACTERIA AND HETEROTROPHIC PLATE COUNT BACTERIA ATTACHED TO HOUSEHOLD CONTAINERS DURING THE STORAGE OF DRINKING GROUNDWATER IN A RURAL COMMUNITY

The study covered on Mgquba village (Eastern Cape) revealed that 90% of families use drinking groundwater from the standpipes. Seventy four percent of the population use polyethylene (PE) containers and 26% galvanized steel (GS) containers for the storage of their drinking water. The average duration of storage of water also varied: 6% store water for about 1-2 days; 14 % for about 3 days; 18 % for few hours (± 5-12 h) and 2% for about 7 days. This study considered the average duration of 3 days. Seven standpipes were used to monitor bacterial quality of drinking groundwater. The detection of fecal coliform and heterotrophic plate count (HPC) bacteria attached on the surfaces of household containers during the storage of drinking groundwater was performed by exposing PE and GS coupons in the appropriate household containers for a period of 72 h. The experiment was performed as the rural communities normally collect and store their water. Membrane filter and spread plate procedure were used to enumerate fecal coliform and HPC attached to household containers, respectively. The adhesion of HPC bacteria on the PE and GS surfaces was obvious within 24 h after exposure. The yield in HPC bacteria was significantly higher on PE than on GS coupons (p<0.003) during the study period. A comparison between source waters showed that attached HPC bacteria on PE and GS appeared to be significantly different both within the various standpipes and also between the various standpipes. While the attachment of fecal coliform was visible on PE coupons exposed to drinking water from standpipes 4 and 5, no fecal coliforms were detected on GS coupons during the study period. This study indicated that PE containers enhanced the growth of Escherichia coli when compared to GS containers. Based on the results of this study, it is recommended that rural communities must consider the GS containers for the storage of their drinking groundwater.
High-dose therapy with autologous stem cell support for lymphoma – from experimental to standard treatment

Stein Kvaløy Division of Cancer, Surgery and Transplantation Oslo University Hospital and Institute of Clinical Medicine Faculty of Medicine University of Oslo High-dose therapy with autologous stem cell support (HDT) has been a therapeutic option for lymphomas in Norway since as far back as 1987. By restoring bone marrow function through reinfusion of the patient’s own stem cells, it is possible to administer cancer treatment in higher and otherwise lethal doses, and thereby achieve better treatment results. Originally stem cells were harvested from bone marrow and the high-dose therapy included total body irradiation, but since the mid 1990s stem cells have been harvested by apheresis and the high-dose therapy has consisted of chemotherapy alone (BEAM chemotherapy). In 1995 the treatment was regionalised and since then it has been performed in all health regions. The HDT procedure was introduced as an experimental treatment in clinical studies with international collaboration. The indications have changed over time, and this is now established treatment for a number of types of lymphoma.
A Single Application of Cerebellar Transcranial Direct Current Stimulation Fails to Enhance Motor Skill Acquisition in Parkinson’s Disease: A Pilot Study

Parkinson’s disease (PD) is a progressive neurodegenerative disorder that leads to numerous impairments in motor function that compromise the ability to perform activities of daily living. Practical and effective adjunct therapies are needed to complement current treatment approaches in PD. Transcranial direct current stimulation applied to the cerebellum (c-tDCS) can increase motor skill in young and older adults. Because the cerebellum is involved in PD pathology, c-tDCS application during motor practice could potentially enhance motor skill in PD. The primary purpose was to examine the influence of c-tDCS on motor skill acquisition in a complex, visuomotor isometric precision grip task (PGT) in PD in the OFF-medication state. The secondary purpose was to determine the influence of c-tDCS on transfer of motor skill in PD. The study utilized a double-blind, SHAM-controlled, within-subjects design. A total of 16 participants completed a c-tDCS condition and a SHAM condition in two experimental sessions separated by a 7-day washout period. Each session involved practice of the PGT concurrent with either c-tDCS or SHAM. Additionally, motor transfer tasks were quantified before and after the practice and stimulation period. The force error in the PGT was not significantly different between the c-tDCS and SHAM conditions. Similarly, transfer task performance was not significantly different between the c-tDCS and SHAM conditions. These findings indicate that a single session of c-tDCS does not elicit acute improvements in motor skill acquisition or transfer in hand and arm tasks in PD while participants are off medications.
Weak Form Market Efficiency in Nepalese Stock Market Indices

This paper analyses the weak-form market efficiency of the Nepalese stock market based on daily observation from Jan 23, 2019 to Jan 20, 2021, regarding returns of NEPSE, the composite index of Nepalese stock market, returns of banking sub-index and returns of manufacturing and processing sub-index. The study is conducted employing five tests of random walk i.e. Normality tests, Runs test, Autocorrelation functional test, Unit root test, and Variance ratio test. All tests produced consistent results except for the banking sub-index and manufacturing and production sub-index under variance ratio test and run test. It is concluded that the Nepalese stock market is not in weak-form market efficiency. The assumptions of an efficient stock market may not be materialized in the Nepalese context being a small and young market. The findings of the study report that investors have a favorable opportunity to predict stock price and generate abnormal gain from the Nepalese stock market.
The impact of intensive trauma-focused treatment on sexual functioning in individuals with PTSD

Background Individuals with posttraumatic stress disorder (PTSD) often experience sexual disturbances. Objective To determine whether intensive trauma-focused treatment is associated with an improvement in sexual functioning (i.e., sexual satisfaction and sexual desire) in individuals with PTSD. Method In total, 227 patients with PTSD (68.7% women, mean age = 40.97) participated in an intensive eight-day trauma-focused treatment program consisting of prolonged exposure, eye movement and desensitization and reprocessing (EMDR) therapy, physical activity, and psychoeducation. Patients were assessed (i.e., Clinician Administered PTSD Scale and Sexual Functioning Questionnaire) pre- and post-treatment and at 6-months follow-up. Results Sexual satisfaction and sexual desire increased significantly associated with trauma-focused treatment from pre-treatment to 6-months follow-up, albeit the effect sizes were small (Cohen’s d = 0.39 and 0.17, respectively). Although men reported greater overall sexual desire than women, sexual functioning improved after treatment in both men and women. Furthermore, those with remission of PTSD reported greater sexual functioning post-treatment and at 6-months follow-up, than those without remission. However, changes in PTSD symptoms associated with treatment were not predictive of the level of sexual satisfaction or sexual desire 6 months after treatment. Conclusion The results of this uncontrolled study suggest that intensive treatment for PTSD can have beneficial effects on sexual satisfaction and desire in both men and women; however, this may not necessarily be due to a decrease in PTSD symptoms.

Application of the Joint Frailty Copula Model for Analyzing Time to Relapse and Time to Death of Women with Cervical Cancer

Background Worldwide, there were 12.7 million new cervical cancer cases, of which 5.6 million took place in industrialized nations and 7.1 million in underdeveloped nations. In eastern, western, middle, and southern Africa, it is the main cancer-related cause of death in female patients. In Ethiopia, cancer was responsible for roughly 5.8% of all fatalities. This study makes use of sophisticated statistical models that take into account population heterogeneity in terms of frailty and dependence between two endpoints in terms of copulas. Methods Based on hospital registry data, this retrospective study intends to examine the time to relapse and time to death of cervical cancer. This study analyzes 907 cervical cancer-positive women from various parts of Ethiopia. The copula model was used to link time to relapse and time to death of women with cervical cancer. Shared frailty model was used to incorporate unexplained heterogeneity for women with cervical cancer patients. Results Of the 907 cervical cancer patients, 275 (30.32%) experienced a relapse, 353 (38.92%) died, and 554 (61.08%) were censored. Age, smoking status, family planning, HIV status, family history, abortion, and stage are the most reliable predictors of both time to relapse and time to death of cervical cancer patients. The estimate of the copula parameter (θ = 1.476, 95% CI: 1.082, 1.870) shows moderate amount of dependence between time to relapse and time to death (Kendall’s rank correlation (τ) = 0.425). The estimate of the variability (heterogeneity) parameter in the population of clusters (region) is η = 0.495, 95% CI: 0.101, 0.889. Conclusion Age, smoking status, family planning, HIV status, family history, abortion, and more advanced stage significantly increase the risk of relapse and death of female cervical patients. There was a significant association between the time to relapse and the time to die for women with cervical cancer. There was a significant heterogeneity effect in the Tikur Anbessa Specialized Hospital.
LATE QUATERNARY CRUSTAL DEFORMATION AT THE APEX OF THE MOUNT MCKINLEY RESTRAINING BEND OF THE DENALI FAULT, ALASKA

OF THESIS LATE QUATERNARY CRUSTAL DEFORMATION AT THE APEX OF THE MOUNT MCKINLEY RESTRAINING BEND OF THE DENALI FAULT, ALASKA The tallest mountain in North America, Mount McKinley is situated inside a sharp bend in the right‐lateral Denali fault. This anomalous topography is clearly associated with the complex geometry of the Denali fault, but how this topography evolves in conjunction with the adjacent strike‐slip fault is unknown. To constrain how this fault bend is deforming, the Quaternary fault‐related deformation on the opposite side of the Denali fault from Mount McKinley were documented through combined geologic mapping, active fault characterization, and analysis of background seismicity. My mapping illustrates an east‐west change in faulting style where normal faults occur east of the fault bend and thrust faults predominate to the west. These faults offset glacial outwash terraces and moraines which, with tentative correlations with the regional glacial history, provide fault slip rates that suggest that the Denali fault bend is migrating southwestward. The complex and elevated regional seismicity corroborates the style of faulting associated with the fault bend and provide additional subsurface control on the location of active faults. Seismologic and neotectonic constraints suggest that the maximum compressive stress axis rotates from vertical east of the bend to horizontal and Denali fault‐normal west of the bend.
Association of Anthropometric and CT-Based Obesity Indices with Subclinical Atherosclerosis

Aim: Few studies have compared the strength in the associations of anthropometric and computed tomography (CT)-based obesity indices with coronary artery calcification (CAC), aortic artery calcification (AoAC), and aortic valve calcification (AVC). Methods: We assessed cross-sectcional associations of anthropometric and CT-based obesity indices with CAC, AoAC, and AVC. Anthropometric measures included body mass index (BMI), waist circumference, hip ircumference, waist-to-hip circumference ratio, and waist-to-height ratio in 931 men (mean age, 63.7 years) from a population-based cohort. CT images at the L4/5 level were obtained to calculate the areas of abdominal visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), total adipose tissue (TAT), VAT-to-SAT ratio (VSR), and VAT-to-TAT ratio (VTR). CAC, AoAC, and AVC were quantified using the Agatston score based on CT scanning. Results: CAC, AVC, and AoAC were present in 348 (62.6%), 173 (18.6%), and 769 (82.6%) participants, respectively. In multivariable models adjusting for age, lifestyle factors, and CT types (electron beam CT and multidetector row CT), anthropometric and CT-based obesity indices were positively associated with CAC (p＜0.01). Conversely, VAT-to-SAT ratio and VAT-to-TAT ratio were positively associated with AoAC (p＜0.01). Any obesity indices were not associated with AVC. Conclusions: The strength of the associations of obesity indices with subclinical atherosclerosis varied according to the anatomically distinct atherosclerotic lesions, among men.
Guided Superficial Enhanced Fluid Fat Injection (SEFFI) Procedures for Facial Rejuvenation: An Italian Multicenter Retrospective Case Report

Background: The aging process starts in the center of the face, in the periocular region and around the mouth, with a combination of volume loss, tissue descent, deepened wrinkles, and the loss of skin structure and quality. Recently, several studies have demonstrated the efficacy of therapies based on autologous adipose tissue grafting, which leverages the properties of stromal vascular fraction (SVF) and adipose-derived mesenchymal stem cells (ADSCs) to accelerate the regenerative processes of the skin. This study aims to verify the ability of guided superficial enhanced fluid fat injection (SEFFI) in the facial area to correct volume loss and skin aging, proving that this standardized procedure has a very low rate of complications. Methods: We retrospectively collected data from 2365 procedures performed in Italian centers between 2019 and 2021. Guided SEFFI was performed alone or combined with cosmetic treatments, including the use of hyaluronic acid filler, suspension threads, synthetic calcium hydroxylapatite, botulin toxin, and microneedling. Results: guided SEFFI was used alone in more than 60% of the patients and in all facial areas. In about one-tenth of the patients, guided SEFFI was combined with a botulin toxin treatment or hyaluronic acid filling. Other procedures were used more rarely. Ecchymosis in the donor or injection sites was the most frequent adverse event but was only observed in 14.2% and 38.6% of the patients, respectively. Conclusions: The guided SEFFI technique is standardized and minimally invasive, leading to very few complications. It constitutes a promising antiaging medical treatment that combines effectiveness, safety, and simplicity.
Grapevine plantlets respond to different monochromatic lights by tuning photosynthesis and carbon allocation

Abstract The quality of planting materials is the foundation for productivity, longevity, and berry quality of perennial grapevines with a long lifespan. Manipulating the nursery light spectrum may speed up the production of healthy and high-quality planting vines but the underlying mechanisms remain elusive. Herein, the effects of different monochromatic lights (green, blue, and red) on grapevine growth, leaf photosynthesis, whole-plant carbon allocation, and transcriptome reprograming were investigated with white light as control. Results showed that blue and red lights were favorable for plantlet growth in comparison with white light. Blue light repressed excessive growth, significantly increased the maximum net photosynthetic rate (Pn) of leaves by 39.58% and leaf specific weight by 38.29%. Red light increased the dry weight of the stem by 53.60%, the starch content of the leaf by 53.63%, and the sucrose content of the stem by 230%. Green light reduced all photosynthetic indexes of the grape plantlet. Photosynthetic photon flux density (PPFD)/Ci–Pn curves indicated that blue light affected photosynthetic rate depending on the light intensity and CO2 concentration. RNA-seq analysis of different organs (leaf, stem, and root) revealed a systematic transcriptome remodeling and VvCOP1 (CONSTITUTIVELY PHOTOMORPHOGENIC 1), VvHY5 (ELONGATED HYPOCOTYL5), VvHYH (HY5 HOMOLOG), VvELIP (early light-induced protein) and VvPIF3 (PHYTOCHROME INTERACTING FACTOR 3) may play important roles in this shoot-to-root signaling. Furthermore, the correlation network between differential expression genes and physiological traits indicated that VvpsbS (photosystem II subunit S), Vvpsb28 (photosystem II subunit 28), VvHYH, VvSUS4 (sucrose synthase 4), and VvALDA (fructose-bisphosphate aldolase) were pertinent candidate genes in responses to different light qualities. Our results provide a foundation for optimizing the light recipe of grape plantlets and strengthen the understanding of light signaling and carbon metabolism under different monochromatic lights.

Medicinal plants utilized for fitness disorders treatment by ethnic groups in Papua and West Papua Province, Indonesia

Papua is one of Indonesia’s islands with a large biological wealth, including medicinal plants. This study aimed to identify the utilization of medicinal plants by selected traditional healers who met inclusion criteria to treat fitness disorders in ethnic groups of Papua and West Papua. Data was collected through interviews, observation, and sample collection. Data quantification was done by analyzing the use value parameters, simple preference ranking exercise, multi-health purpose species rank, and the plant parts value. This study revealed 43 concoction information details and identified the use of 24 plant species distributed in 19 families among 19 healers in 10 ethnic groups in Papua and West Papua. Cymbopogon citratus (DC.) Stapf (12.12%) and leaves (57.35%) were determined as the most prominent species and plant parts used. Morinda citrifolia was identified as the species with the biggest number of other treatable diseases, with a total score of 85. The most used plant families were Myrtaceae and Poaceae, each with a percentage of 12.12%. The study showed the critical role of medicinal plants and traditional healers in community health. However, conservation efforts must be initiated immediately since almost 40% of traditional healers still harvest the available plants and make no cultivation efforts.
