In this paper, we propose a class of ACD-type models that accommodates overdispersion, intermittent dynamics, multiple regimes, and sign and size asymmetries in financial durations. In particular, our functional coefficient autoregressive conditional duration (FC-ACD) model relies on a smooth-transition autoregressive specification. The motivation lies on the fact that the latter yields a unive...

OBJECTIVES This study was designed to assess whether a new method of cardiopulmonary resuscitation (CPR), termed active compression-decompression CPR, or ACD-CPR, improves organ perfusion when compared with standard (S) CPR in a dog model of ventricular fibrillation. BACKGROUND ACD-CPR has recently been shown to improve hemodynamic and respiratory parameters during cardiac arrest when compare...

The multilayered epidermis is established through a stratification program, which is accompanied by a shift from symmetric toward asymmetric divisions (ACD), a process under tight control of the transcription factor p63. However, the physiological signals regulating p63 activity in epidermal morphogenesis remain ill defined. Here, we reveal a role for insulin/IGF-1 signaling (IIS) in the regula...

The security of several homomorphic encryption schemes depends on the hardness of variants of the approximate common divisor (ACD) problem. We survey and compare a number of latticebased algorithms for the ACD problem, with particular attention to some very recently proposed variants of the ACD problem. One of our main goals is to compare the multivariate polynomial approach with other methods....

Abstract Background Iatrogenic aortocoronary dissection (ACD) is a rare but potentially devastating complication of cardiac catheterisation. We describe case an iatrogenic ACD following catheter engagement and balloon inflation the proximal right coronary artery (RCA) during elective percutaneous intervention (PCI). Case summary An 81-year-old woman presented with acute inferior wall ST-elevati...

anemia of chronic diseases (acd) is a common problem in patients with infectious diseases and can influence the quality of life and patients' survival. despite the clinical importance of acd, data are still lacking regarding this problem in the infectious diseases. this study aimed to evaluate the prevalence, related factors, outcome and approaches to anemia in the infectious diseases ward...

Pathogenic memory T cells are implicated in the local relapse of allergic contact dermatitis (ACD), vitiligo and psoriasis. Here we investigate how resident initiate relapses response to allergen Methylisothiazolinone (MI). MI–related ACD was sampled two months years after resolution disease. were activated skin explants with MI or pan T-cell agonist OKT-3. Epidermis analysed by RNAseq, Nanostr...

BACKGROUND AND OBJECTIVES In order to gain a better insight into the pathogenesis of the anemia of chronic disease (ACD) accompanying rheumatoid arthritis, we analyzed the density of the integrins very late antigen (VLA) 4 and VLA-5 on the surface of erythroblasts from bone marrow in patients with rheumatoid arthritis. We also measured the concentration of interleukin (IL) 3 and tumor necrosis ...

BACKGROUND To evaluate how differences in ocular biometry affects the Hoffer Q, Holladay 1, SRK/T, and Haigis intraocular lens power calculation formulae predictions. METHODS This study was performed on 91 eyes of 91 patients who underwent uneventful cataract surgery. Ocular biometry values were measured using the IOL Master 500, and intraocular lens (IOL) power was calculated using the Haigi...
