Pulmonary vascular resistance (PVR) is traditionally used to describe pulmonary hemodynamic characteristics. However, it does not take into account pulmonary artery compliance (Ca) or pulsatile flow. The product of PVR and Ca is known as RC time. Previous studies assert that the PVR-Ca relationship is fixed and RC time is constant between health and disease states. We hypothesized that RC time ...

Multiple ribonucleases are widely found in living organisms, but the function and regulation of individual ribonucleases are still not clear. In the present study, we found that one oocytic ribonuclease, RC-RNase, is developmentally expressed in the liver and stored in the oocyte of the bullfrog, while another ribonuclease, RC-RNase L1, is constitutively expressed and retained in the liver at a...

Culture-based studies have shown that Streptococcus mutans and lactobacilli are associated with root caries (RC). The purpose of the present study was to assess the bacterial diversity of RC in elderly patients by use of culture-independent molecular techniques and to determine the associations of specific bacterial species or bacterial communities with healthy and carious roots. Plaque was col...

Spheroidal aggregates of embryonic chick ventricle cells were brought into contact and allowed to synchronize their spontaneous beats. Action potentials were recorded with both intracellular and extracellular electrodes. The degree of electrical interaction between the newly apposed aggregates was assessed by measuring the delay or latency (L) between the entrained action potentials, and by det...

Panax ginseng and its major components, the ginsenosides, are widely used in oriental medicine for the prevention of various disorders. In the present study, the inhibitory activity of ginsenoside Rc on adipogenesis was investigated using the 3T3-L1 cell line. The results obtained showed that Rc reduced the proliferation and viability of 3T3-L1 preadipocytes in a dose-dependent manner. Treatmen...

Gao and Sarkar have proposed Location Consistency (LC), the weakest memory model described in the literature to date for shared memory architectures. The advantage of LC is that it does not require invalidation/update messages across processors, thus dispensing with cache snooping or directories. Gao and Sarkar have argued that, although LC is strictly weaker than Release Consistency (RC), it i...

Faithful inheritance of genetic information requires that DNA be copied only once each cell cycle. Initiation of DNA replication involves the establishment of a prereplication complex (pre-RC) and subsequent activation by CDK/cyclins, converting the pre-RC to a post-RC. The origin recognition complex (ORC), Cdc6p, and the MCM proteins are required for establishing the pre-RC. We show that all s...

Frequent counting is a very so often required operation in machine learning algorithms. A typical machine learning task, learning structure of Bayesian network (BN for short) based on metric scoring, is introduced as an example task which heavily relies on frequent counting. A fast calculation method for frequent counting enhanced with two cache layers is then presented for learning BN . We nam...

Repetitive control (RC) scheme presents an attractive solution to achieve excellent steady-state tracking error and low total harmonic distortion (THD) for periodic signals. RC can produce extremely large gains at fundamental and each harmonic frequency of reference signal to achieve all harmonics suppression. However, a DC-AC inverter always has uneven THD distribution, e.g. THD concentrates a...

Few studies have compared outcomes of right colectomy (RC) and left colectomy (LC) with respect to both benign and malignant disease. The objective of this study was to compare outcomes of RC versus LC for benign and malignant disease using a national administrative database of academic medical centers. Using International Classification of Diseases, 9th Revision diagnosis and procedure codes, ...
