Self-consistent relativistic particle-vibration coupling (PVC) model [1] is applied to a systematic study of singleparticle spectra of nuclei ranging from light to superheavy ones [2] and generalized to the case of superfluid systems [3]. An example of the obtained results compared to data is shown in Fig. 1. The column (sph) shows the singleparticle spectra obtained in spherical relativistic m...
The potentiometric response characteristics and analytical applications of a poly(vinyl chloride) (PVC)-free all-solid-state ion-selective electrode for chlorhexidine (CHX) are examined and compared to those of PVC-based solid-state electrode. The PVCfree electrode is prepared by direct incorporation of chlorhexidine-tetraphenyl borate (CHXTPB) as a sensing element into a commercial nail varnis...
In the process of ventricular premature beat (PVC) and normal sinus rhythm (NSR) identification base on electrocardiogram (ECG), there exists problems like negative effect from ECG rhythm and low recognition rate. This paper proposes the electrocardiogram PVC classification algorithm based on support vector machine (SVM) and wavelet algorithm. The algorithm uses the wavelet transform to analyze...
The existing video coding standard H.264 could not provide expected rate-distortion (RD) performance for macroblocks (MBs) with both moving objects and static background and the MBs with uncovered background (previously occluded). The pattern-based video coding (PVC) technique partially addresses the first problem by separating and encoding moving area and skipping background area at block leve...
BACKGROUND Primary vaginal carcinoma (PVC) is a rare malignancy. Established prognostic factors include tumour stage and age at diagnosis. The leucine-rich repeats and immunoglobuline-like domains (LRIG)-1 protein functions as a tumour suppressor, but less is known about the functions of LRIG2 and LRIG3. The present study aimed to evaluate the expression of LRIG proteins and analyse their possi...
The covert security model (Aumann and Lindell, TCC 2007) offers an important security/efficiency trade-off: a covert player may arbitrarily cheat, but is caught with a certain fixed probability. This permits more efficient protocols than the malicious setting while still giving meaningful security guarantees. However, one drawback is that cheating cannot be proven to a third party, which preven...
BACKGROUND Stylets are the most frequently used devices for tracheal intubation, but can be a source of postoperative pharyngeal pain or hoarseness. In this study, we evaluated extraction forces between polyvinyl chloride (PVC) and stannum (Sn) stylets with various lubricants. FINDINGS Using a manikin, we compared extraction forces between PVC and Sn stylets under four different conditions: w...
Poly(vinyl chloride) (PVC) and natural fiber composites were prepared by melt compounding and compression molding. The influence of fiber type (i.e., bagasse, rice straw, rice husk, and pine fiber) and loading level of styrene-ethylene-butylene-styrene (SEBS) block copolymer on composite properties was investigated. Mechanical analysis showed that storage modulus and tensile strength increased ...
Gene expression analysis has many applications in the management of cancer, including diagnosis, prognosis, and therapeutic care. In this context, the reverse transcription quantitative polymerase chain reaction (RT-qPCR) has become the "gold standard" for mRNA quantification. However, this technique involves several critical steps such as RNA extraction, cDNA synthesis, quantitative PCR, and a...
Speech Audio-visual (AV) interaction has been considered for redundancy and complementary properties at the phonetic level but a few experiments have shown a significant role in early auditory analysis. A new paradigm is proposed which uses the pre-voicing component (PVC) excised from a true /b/. When the so called target PVC is added up to a /p/ this leads to the clear perception of /b/. Moreo...
