Aim of this study is to investigate the diagnostic role of serum D-dimer levels for tubo-ovarian abscess (TOA). Patients diagnosed with TOA (n = 36) and matched controls with ovarian cysts (n = 39) were collected prospectively. Patients in the 2 groups were compared on the basis of size of TOA or cyst, demographic characteristics, and serum d-dimer levels. Baseline characteristics of both group...

PURPOSE The transobturator adjustable tape (TOA) sling operation is a new procedure that allows for the adjustment of tension after surgical intervention, thus permitting correction of postoperative incontinence or obstruction. The aim of this study was to compare the efficacy and safety of TOA with that of the transobturator tape (TOT) procedure. MATERIALS AND METHODS Between 2008 and 2009, ...

Background and Aim: Evaluation of the treatment outcome is an important stage in every healthcare system, including orthodontics. This study aimed to assess the atti-tude and practice regarding treatment outcome assessment (TOA) among Iranian orthodontists. Materials and Methods: In this cross-sectional survey, a questionnaire was developed, which consisted of demographic, attitude, and practi...

In this paper, a novel statistical approach is presented for time-of-arrival (TOA) estimation based on first path (FP) pulse detection using a sub-Nyquist sampling ultra-wide band (UWB) receiver. The TOA measurement accuracy, which cannot be improved by averaging of the received signal, can be enhanced by the statistical processing of a number of TOA measurements. The TOA statistics are modeled...

Tubo-ovarian abscess (TOA) is a severe sequele of pelvic inflammatory disease. The diagnosis is dependent on the aspects of medical history, physical examination, laboratory tests and imaging. However, the dilemma exists in differentiation of TOA and ovarian malignant tumor sometimes. We present a case of TOA misdiagnosed as pelvic malignancy because of its untypical clinical features, malignan...

In cooperative localization systems, wireless nodes need to exchange accurate position-related information, such as time-of-arrival (TOA) and angle-of-arrival (AOA), in order to obtain accurate location information. One alternative for providing accurate position-related information is to use ultra-wideband (UWB) signals. High time resolution of UWB signals presents a potential for very accurat...

In this paper, obtaining time of arrival (TOA) measurements in a sensor network is investigated. Differentiating these TOA measurements provides the Time Difference of Arrival (TDOA) measurements between sensor pairs. An approach is proposed to estimate the TOA at a single sensor in a semi-passive scenario. The theoretical investigation is supported by field trials. This experimental analysis p...

As more location aware services are emerging in the market, the needs for accurate and reliable localization has increased and in response to this need a number of technologies and associated algorithms are introduced in the literature. Severe multipath fading in indoor areas, poses a challenging environment for accurate localization. In this article we provide a comprehensive overview of exist...
