To find efficient screening methods for high dimensional linear regression models, this paper studies the relationship between model fitting and screening performance. Under a sparsity assumption, we show that a subset that includes the true submodel always yields smaller residual sum of squares (i.e., has better model fitting) than all that do not in a general asymptotic setting. This indicate...

We study the production of hadrons in nucleus-nucleus collisions within the Parton-Hadron-String Dynamics (PHSD) transport approach that is extended to incorporate essentials aspects of chiral symmetry restoration (CSR) in the hadronic sector (via the Schwinger mechanism) on top of the deconfinement phase transition as implemented in PHSD. The essential impact of CSR is found in the Schwinger m...

Prospects are examined for the detection of a slow decay of the lightest neutralino (or any other longlived particles) at the CERN LHC and at Very Large Hadron Collider (VLHC). We rst point out that such hadron colliders will become the \neutralino factory" producing 10{10 neutralinos/yr, if gluinos and/or squarks actually exist below O(1) TeV. The lightest neutralino (~ 01), usually assumed to...

Purpose: To define the maximum tolerated dose and the dose-limiting toxicity of the kinase modulator UCN-01 administered as a short (1-3 hours) infusion to patients with refractory solid tumors and to evaluate the pharmacokinetics of this novel agent. Experimental Design: Twenty-four patients (15 men, 9 women; median age, 59 years; Eastern Cooperative Oncology Group Performance Status, 0-2) wer...

An effective combination of oxidation medium, ball milling parameters, and copper additive disperstiy ensuring fast aluminum scrap reaction with high hydrogen yield, was suggested. Different parameters (5, 10, 15 mm steel balls; 1 2 h; unidirectional bidirectional rotation modes) were tested for Al-10 wt.% Cu (50–70 μm) composition. The samples milled 5 (2 h) 10 (1 balls contained undesirable i...

The present study was conducted to compare the four different extractants widely used in boron (B) determination soils and screen most suitable extractant for acidic (Alfisols) alkaline (Vertisols) of Odisha Andhra Pradesh. A total 200 surface soil samples were collected across two sites (100 from each site) representing pH ranges. Hot-water-soluble (HWS-B) extraction procedure being B kept as ...
