Background : Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disease affecting the reproductive age women. Objective : To investigate the relationship between PCOS and breast, ovarian, and endometrial cancer. Search Strategy: Systematic search of PubMed, EMBASE using keywords ‘PCOS’, ‘ovarian cancer’, ‘breast cancer’ and ‘endometrial cancer’. Selection Criteria: The study p...

This paper studies the relay-assisted inter-vehicular communications (IVCs) with double Rayleigh fading vehicle-to-vehicle links. The OPA (optimal power allocation) solution is derived through maximizing source-to-destination channel capacity assuming amplify-and-forward relaying. The outage performance is discussed and the lower bound on outage probability at medium to high SNR (signal-to-noise r...

This paper explores the relay-assisted transmission system with mobile-to-mobile links undergo cascaded Rayleigh fading. The BER (bit error rate) bounds of the system are derived through mathematic analysis assuming amplify-and-forward relaying. And the OPA (optimal power allocation) method is discussed which is based on minimizing Chernoff bound on BER performance. The paper presents two classica...

This paper studies the inter-vehicular communication (IVC) system where a vehicle transmits information to another vehicle assisted by an access point (AP), which may be mounted along a street or on a rooftop. The paper first presents the double-Rayleigh fading vehicle-to-vehicle (V2V) channel model and the amplify-and-forward (AF) relaying system. And then the optimal power allocation (OPA) solut...

The paper studies two moving vehicles exchanging messages assisted by another vehicle which is used as a relay. All the vehicle-to-vehicle (V2V) links are modeled as flat double-Rayleigh fading. Based on this particular channel model, the OPA (optimal power allocation) solutions are derived through maximizing source-to-destination channel capacity on the assumptions of amplify-and-forward relaying...

The paper explores the relay-assisted IVC (inter-vehicular communication) systems with double-Rayleigh fading V2V (vehicle-to-vehicle) links for both APA (access point assisted) and VA (vehicle assisted) schemes. The OPA (optimal power allocation) solutions are derived through maximizing source-to-destination channel capacity assuming amplify-and-forward relaying. Furthermore, the outage performan...

This paper aims to study the reverse osmosis membranes which can desalinate seawater. Mechanism of water seepage has been studied by XRD analysis, scanning electron microscope and other methods. Effects outside temperatures and soil moisture conditions on the water infiltration rate of the membrane are explored by comparison. The experimental results reveal that the water seepage through the dens...

Background The purpose of this study was to evaluate the role of differentiation related genes (DRGs) in tumor associated macrophages (TAMs) in non small cell lung cancer (NSCLC). Method Single cell RNA seq (scRNA seq) data from GEO and bulk RNA seq data from TCGA were analyzed to identify DRGs using trajectory method. Functional gene analysis was carried out by GO/KEGG enrichment analysis. The...

In recent years, 2D Convolutional Networks-based video action recognition has encouragingly gained wide popularity; However, constrained by the lack of long-range non-linear temporal relation modeling and reverse motion information modeling, the performance of existing models is, therefore, undercut seriously. To address this urgent problem, we introduce a startling Temporal Transformer Network wi...
