We estimate a large Bayesian time-varying parameter vector autoregressive (TVP-VAR) model of daily stock return volatilities for 35 U.S. and European financial institutions. Based on that model we extract a connectedness index in the spirit of Diebold and Yilmaz (2014) (DYCI). We show that the connectedness index from the TVP-VAR model captures abrupt turning points better than the one obtained...

OBJECTIVE The purpose of this work is to analyze the clinical results of treating severe mitral stenosis (MS) with mild to moderate functional tricuspid regurgitation (FTR) with mitral valve replacement (MVR) alone or together with two different methods of tricuspid valvuloplasty (TVP). PATIENTS AND METHODS We split 132 patients into three groups: simple MVR with 47 cases (control group), MVR...

BACKGROUND AND PURPOSE Adjacent VCF frequently occurs after percutaneous vertebroplasty. Our aim was to evaluate PrVP in the prevention of PVNO-adjacent VCF. MATERIALS AND METHODS Radiographs of 68 patients who initially presented with a single-level unhealed fracture and underwent vertebroplasty were retrospectively reviewed for the occurrence of PVNO fracture. Patients in the nonpreventive ...

Principal component analysis (PCA) is an unsupervised method for learning low-dimensional features with orthogonal projections. Multilinear PCA methods extend PCA to deal with multidimensional data (tensors) directly via tensor-to-tensor projection or tensor-to-vector projection (TVP). However, under the TVP setting, it is difficult to develop an effective multilinear PCA method with the orthog...

Proteinuria is a major determinant of adverse renal outcome, and its reduction slows renal progression in glomerular diseases. However, the optimal target of proteinuria in glomerular diseases is unclear, and discrepancies in the definition of proteinuria produce ambiguous findings. Here we investigated the optimal target of proteinuria by using different definitions of proteinuria. We analyzed...

To examine the hormonal effects of isoflavones, of which soyabean is a rich source, fifteen healthy nonvegetarian premenopausal women were studied over 9 months. They lived in a metabolic suite for between 4 and 6 months where their diet and activity levels were kept constant and their hormonal status was measured over two or three menstrual cycles. During one (control) menstrual cycle a normal...

Previous publications (e.g. Young, 1978, 1983, 1993a,b, 1998a,b, 1999a,b; Young and Runkle, 1989; Young and Minchin, 1991; Young et al., 1991; Young and Lees, 1993; Young and Beven, 1994; Young and Pedregal, 1997, 1998, 1999) have discussed an approach to nonstationary and nonlinear signal processing based on the identification and estimation of stochastic models with time variable (TVP) or sta...

Time varying parameter (TVP) models have enjoyed an increasing popularity in empirical macroeconomics. However, TVP models are parameter-rich and risk over-…tting unless the dimension of the model is small. Motivated by this worry, this paper proposes several Time Varying dimension (TVD) models where the dimension of the model can change over time, allowing for the model to automatically choose...

This paper argues that elliptical VPs do not necessarily present cases of VP ellipsis. Certain relative clauses that contain elliptical VPs are analysed as instances of transitive verb phrase ellipsis. A storing account of ellipsis resolution is given. Resolution of TVP ellipsis is achieved by resolving a binary relation that derives from an antecedent TVP. This avoids the problem of antecedent...

A patient presented for an elective transcatheter aortic valve replacement with temporary transvenous pacing (TVP) wires placement per protocol. On postoperative day 1, the patient remained stable, so the wires were subsequently removed, after which the patient acutely decompensated, with transthoracic echocardiography revealing pericardial effusion. Emergent pericardiocentesis was performed, a...
