A 12-bit Vernier ring time-to-digital converter (TDC) with time resolution of 8 ps for digital-phase-locked-loops (DPLL) is presented. This novel Vernier ring TDC places the Vernier delay cells and arbiters in a ring format and reuses them for the measurement of the input time interval. The proposed TDC thus achieves large detectable range, fine time resolution, small die size and low power con...

The role of specific PKC isoforms in the regulation of epithelial Cl(-) secretion by Ca(2+)-dependent secretagogues remains controversial. In the developing rabbit distal colon, the bile acid taurodeoxycholate (TDC) acts via intracellular calcium to stimulate Cl(-) transport in adult, but not in young, animals, whereas the PKC activator phorbol dibutyrate (PDB) stimulates Cl(-) transport at all...

OBJECTIVE The objective of this study is to identify the influence of early clinical exposure for undergraduate students on self-perception of different aspects of geriatric dental care. MATERIALS AND METHODS We have selected two different colleges from Japan and India, namely, Tokyo Dental College (TDC), Tokyo, and Government Dental College (GDC), Nagpur, respectively. The GDC students expos...

Skin tissue dielectric constant (TDC) values measured via the open-ended coaxial probe method are useful non-invasive indices of local skin tissue water. However, the effect of skin blood flow (SBF) or skin blood volume (SBV) on TDC values is unknown. To determine the magnitude of such effects, we decreased forearm SBV via vertical arm raising for 5 min (test 1) and increased SBV by bicep cuff ...

OBJECTIVES A thyroglossal duct cyst (TDC) is a frequent congenital midline anomaly of the neck that usually manifests during the first decade of life. We aimed to describe the presentation, management, and outcome of TDC in pediatric and adult cases. METHODS A retrospective observational analysis was conducted for all patients diagnosed and treated for TDC between 2000 and 2014 in a single ce...

BACKGROUND Early diagnosis of breast cancer treatment-related lymphedema (BCRL) is of great importance for longstanding treatment results. Tissue dielectric constant (TDC) and bioimpedance spectroscopy (BIS) both have a potential for early diagnosis, but have not been compared. METHODS AND RESULTS One hundred women, treated for breast cancer with breast surgery, axillary dissection, and radio...

AIM This study aims to compare clinical outcomes in patients with chronic subdural hematoma (CSDH) following twist drill craniostomy (TDC) or burr hole craniostomy (BHC). MATERIAL AND METHODS A prospective cohort study was conducted in the patients who suffered from symptomatic CSDH and received surgical treatment in our department from Jan 2011 to Dec 2013. Each patient was followed 3 months...

Abstract: This paper describes the architecture and performance of a high-resolution time–to– digital converter (TDC) based on a Vernier delay line. The TDC is used as a basic building block for time interval measurement in an ultrasonic liquid flowmeter. Operation of the TDC with 10ps LSB resolution and 1 ms input range has been simulated using library models for 1.2 μm double–metal double–pol...

Thyroglossal duct cyst (TDC) is a cystic expansion of a remnant of the thyroglossal duct tract. Carcinomas in the TDC are extremely rare and are usually an incidental finding after the Sistrunk procedure. In this report, an unusual case of a 36-year-old woman with concurrent papillary thyroid carcinoma arising in the TDC and on the thyroid gland is presented, followed by a discussion of the con...

Tunneled dialysis catheters (TDC) are extensively used for long-term venous hemodialysis access and their use is frequently associated with infectious complications. Catheter-related bacteremia (CRB) is the most common and important infection associated with TDC use and may be caused by a wide variety of Gram-positive or Gram-negative organisms. Prevention of CRB can be difficult despite use of...
