The Performance comparison of Minimum Mean Square Error-based Adaptive Multi-User Detection (MUD) of Direct Sequence-Code Division Multiple Access (DS-CDMA) signals is considered. DS-CDMA is a popular multiple-access technology for wireless communication. But its performance is limited by multiple-access interference (MAI) and multipath distortion. Adaptive techniques, such as least mean square...

Unmanned-aerial-vehicles (UAVs) are intended to be a vital part of beyond 5G (B5G) and 6G communication networks. UAV-to-ground communications in urban populated areas usually exposed highly variable propagation conditions that can often characterized by composite fading channels. This paper provides mathematical framework for the performance evaluation over double-scattered single-shadowed (DS...

Objectives: Down syndrome (DS) may be associated with congenital heart defects (CHD). Folate-metabolizing genes have been suspected as risk factors in DS and in CHD. We investigated the role of methylenetetrahydrofolate reductase (MTHFR) C677T and A1298C polymorphisms and methionine synthase (MTR) A2756G polymorphism as risk factors for CHD in DS offspring. Material and Methods: This study incl...

BACKGROUND AND PURPOSE Dysphagia screening (DS) before oral intake in patients with acute stroke is a hospital-level performance measure. We report outcomes of an initiative to improve compliance to this quality measure. METHODS The design was a pre- versus postintervention comparison study. The Intervention was an electronic medical record-based clinical DS system embedded within stroke admi...

We discuss the synthesis problem of concurrent systems from observations or speciication encoded in data table (information system) Pawlak,1991]. In the paper we rst introduce a new notion of a so-called dynamic information system, and then we apply this notion as a tool for speciication of concurrent systems behaviour Pawlak,1992], Pawlak,1997]. Finally, we present two methods of construction ...

Down syndrome (DS) is one of the most common survivable chromosomal disorders, and is well known to be associated with multiple autoimmune diseases. Multiple sclerosis (MS) is a chronic inflammatory autoimmune demyelinating disease of the central nervous system. An association of DS and other autoimmune disease has been previously reported, and we report one case of DS in coexistence with MS, d...

BACKGROUND Ubiquitous health is defined as a dynamic network of interconnected systems that offers health services independent of time and location to a data subject (DS). The network takes place in open and unsecure information space. It is created and managed by the DS who sets rules that regulate the way personal health information is collected and used. Compared to health care, it is imposs...

Down syndrome (DS) is the most common chromosomal abnormality among live-born infants. Respiratory tract infections are the most important cause of mortality in individuals with DS at all ages. In recent decades several studies have been performed to elucidate abnormalities of the immune system in DS. However, the influence of the immune system on the occurrence of respiratory tract infections ...
