We first provide an overview of some of the latest developments in wireless communications using multiple transmitters and multiple receivers. We point out the importance of SNR control in fast random fading environment. For applications where large antenna arrays are not suitable, we introduce the concept of wireless antennas or wireless relays that are(More)
In this paper we present a process model for developing usable cross-cultural websites. Compatible with ISO 13407, the process model documents an abstraction of the design process focusing on cultural issues in development. It provides a framework in which a variety of user-based and expert-based techniques for analysis and design are placed within the(More)
Aim Predictions of ecosystem responses to climate warming are often made using gap models, which are among the most effective tools for assessing the effects of climate change on forest composition and structure. Gap models do not generally account for broad-scale effects such as the spatial configuration of the simulated forest ecosystems, disturbance, and(More)
For ad hoc mobile networks, parallel wireless relays with space-time modulation have recently been discovered, and their potential to increase network capacity has been found to be significant. In this paper, we provide an analytical study of the diversity factor achievable by two relays with orthogonal space-time modulation. Unlike two transmitters or two(More)
OBJECTIVE The objective of this study was to assess the detection rate of previous cesarean delivery scar (PCDS) defect by transvaginal ultrasonography (TVU) and to evaluate the effectiveness of resectoscopic surgery to correct this anatomic defect. STUDY DESIGN In all, 57 women were included in our study. A diagnosis of a PCDS defect was established by(More)
OBJECTIVE To report a case of combined intrauterine and interstitial twin pregnancies after bilateral salpingectomy and IVF with replacement of three embryos. DESIGN Case report. SETTING University hospital. PATIENT(S) A 31-year-old woman known to have bilateral salpingectomy for ectopic pregnancies who underwent IVF. INTERVENTION(S) Laparotomy. (More)
The behavior of several landscape pattern metrics were tested against various pattern scenarios generated by neutral landscape models, including number of classes, scale-map extent, scale-resolution, class proportion, aggregation level—RULE, and aggregation level—SimMap. The results demonstrate that most of the metrics are sensitive to certain pattern(More)
For mobile ad hoc networking, relaying is one of the most fundamental functions. The traditional relaying strategy is serial, where data packets hop from a single node to another, and the nodes neighboring a transmitting node or a receiving node are suppressed from transmission to avoid radio interference. We consider a parallel relaying strategy where(More)
BACKGROUND Patients harboring activating mutations in epidermal growth factor receptors (EGFR) are particularly sensitive to EGFR tyrosine kinase inhibitors (TKIs). However, most patients develop an acquired resistance after a period of about 10 months. This study focuses on the therapeutic effect of NVP-BEZ235, a dual inhibitor of(More)
Prediction of forest fire ignition may aid in forest fire vigilance and monitoring, and in prioritizing forest fuel treatments. In this paper, we chose easily obtained spatial variables pertaining to topography, vegetation types, meteorological conditions, climate, and human activity to predict forest fire ignition in Heilongjiang province, China, using(More)
