INTRODUCTION Single lead atrial synchronous ventricular pacing (VDD) is increasingly being used in place of conventional dual chamber pacing (DDD) for patients with atrioventricular block and preserved sinus node function. Compared to the latter, VDD pacemakers provide similar haemodynamic benefits derived from atrial synchronous pacing, with the added benefit of an easier implant procedure. ...

Oral health is a reflection of systemic health. The various nutritional deficiencies not only affect the but also have an impact on oral prevalence Vitamin D deficiency (VDD) rampant globally. (VD) essential for skeletal growth during childhood and adulthood has great tissues odontogenesis. VDD several implications from to adulthood. VD can negatively influence mother child supplementation brin...

Ultra-low power applications often require several kb of embedded memory and are typically operated at the lowest possible operating voltage (VDD) to minimize both dynamic and static power consumption. Embedded memories can easily dominate the overall silicon area of these systems, and their leakage currents often dominate the total power consumption. Gain-cell based embedded DRAM arrays provid...

Design of large-scale complex engineered systems (LSCES) depends on a large number of individuals. The design process of LSCES involves multiple organizations and numerous people working at different levels of these organizations. The current approach to designing LSCES is through traditional Systems Engineering (SE) practices, where the preferences of the stakeholders are communicated down the...

The recent years have witnessed a considerable rise in the number of vehicles, which has placed transportation infrastructure and traffic control under tremendous pressure. Yielding timely accurate flow information is essential development strategies. Despite continual advances wealth literature available intelligent system (ITS), there lack practical counting system, readily deployable on edge...

To achieve both of a high peak performance and low average power characteristics, frequency-voltage cooperative control processor has been proposed. The processor schedules its operating frequency according to the required computation power. Its operating voltage or body bias voltage is adequately modulated simultaneously to effectively cut down either switching current or leakage current, and ...

Aims Obesity is a risk factor for vitamin D deficiency (VDD), because the lipid soluble vitamin D can be sequestered in adipose tissue. Although it was suggested that higher dose of vitamin D might be required to treat VDD in obese individuals, little is known about treatment responses in overweight children. We investigated the response to vitamin D replacement in normal weight and overweight ...

Our survey looked at current practice amongst GPs in the West Midlands where there is a high percentage of ethnic minorities who are predisposed to VDD as well as being diabetics. Clinicians need to be aware of the relationship between VDD and DR, with a view to tackling both where possible. We recommend investigating VD levels and commencing treatment early, in the light of the literature revi...

As one type of efficient unsupervised learning methods, clustering algorithms have been widely used in data mining and knowledge discovery with noticeable advantages. However, based on density peak limited effect varying distribution (VDD), equilibrium (ED), multiple domain-density maximums (MDDM), leading to the problems sparse cluster loss fragmentation. To address these problems, we propose ...
