Towards an Understanding of the New Charm and Charm-Strange Mesons

The observation of the D_{sJ}^*(2317), D_{sJ}(2460), and SELEX D^*_{sJ}(2632) states with properties differing considerably from what was expected has led to a renewed interest in hadron spectroscopy. In addition to these states, non-strange partners of the D_{sJ} states have also been observed. Understanding the D_0^* and D_1' states can provide important insights into the D_{sJ} states. In this contribution I examine quark model predictions for the D_0^* and D_1' states and discuss experimental measurements that can shed light on them. I find that these states are well described as the broad, j=1/2 non-strange charmed P-wave mesons. In the latter part of this writeup I discuss the c bar{s} possibilities for the SELEX D^*_{sJ}(2632) and measurements that can shed light on it.Comment: Talk presented at the 1st Meeting of the APS Topical Group on Hadronic Physics (Fermilab, Oct 24-26, 2004). 4 pages uses jpcon

The ALICE CPV Detector

The Charged-Particle Veto (CPV) detector of ALICE at the LHC is presented. Physics motivation for the detector, its construction and operation in physics runs are shortly discussed. Readout electronics and data taking conditions are described. Special attention is focused on CPV automation via the detector control system. Different states of the detector and protection algorithms implemented into the control system are described

The role of chemokine genes in the formation of terminal stage of chronic renal failure

The data on the role of chemokine genes (+1931A/T CCL4, A/G CXCL11 (rs4512021), -403A/G CCL5, C/G CCL2 (rs2857657), -801G/A CXCL12) in the formation of terminal stage of chronic renal failure, in patients with chronic glomerulonephritis, is presented in the work. It was established, that the allele A CXCL11 (rs4512021) (OR = 1.65) was the marker for the development of terminal stage of chronic renal insufficiency, and the genotype GG CXCL11was a protective factor for the development of terminal stage of chronic renal failure (OR = 0.22

Nonlocality, Bell's Ansatz and Probability

Quantum Mechanics lacks an intuitive interpretation, which is the cause of a generally formalistic approach to its use. This in turn has led to a certain insensitivity to the actual meaning of many words used in its description and interpretation. Herein, we analyze carefully the possible mathematical meanings of those terms used in analysis of EPR's contention, that Quantum Mechanics is incomplete, as well as Bell's work descendant therefrom. As a result, many inconsistencies and errors in contemporary discussions of nonlocality, as well as in Bell's Ansatz with respect to the laws of probability, are identified. Evading these errors precludes serious conflicts between Quantum Mechanics and both Special Relativity and Philosophy.Comment: 8&1/2 pages revtex; v2: many corrections, clairifications & extentions, all small; v3: editorial scru

Fixed Effect Estimation of Large T Panel Data Models

This article reviews recent advances in fixed effect estimation of panel data models for long panels, where the number of time periods is relatively large. We focus on semiparametric models with unobserved individual and time effects, where the distribution of the outcome variable conditional on covariates and unobserved effects is specified parametrically, while the distribution of the unobserved effects is left unrestricted. Compared to existing reviews on long panels (Arellano and Hahn 2007; a section in Arellano and Bonhomme 2011) we discuss models with both individual and time effects, split-panel Jackknife bias corrections, unbalanced panels, distribution and quantile effects, and other extensions. Understanding and correcting the incidental parameter bias caused by the estimation of many fixed effects is our main focus, and the unifying theme is that the order of this bias is given by the simple formula p/n for all models discussed, with p the number of estimated parameters and n the total sample size.Comment: 40 pages, 1 tabl

Acute Heart Failure in a Pregnant Woman with Preeclampsia: a Rare Case of Takotsubo Syndrome

The mechanisms of takotsubo syndrome, better known as stress-induced cardiomyopathy, are not fully understood. The article presents a clinical case of the development of acute left ventricular failure in a 39-year-old pregnancy against the background of severe preeclampsia. Echocardiography revealed a decrease in global myocardial contractility, hypo-akinesia of the apex and all median parts of the left ventricle, hyperkinesis of the basal parts. After 2 weeks, myocardial contractility was normal, no contractility impairment was found. Two months after the acute episode of the disease, magnetic resonance imaging of the heart was performed, according to which no pathological changes were detected. Based on the clinical picture, electrocardiogram changes, laboratory data and typical transient echocardiographic changes, it was suggested that the patient had takotsubo syndrome
