We give a brief review of violations of the fluctuation-dissipation theorem (FDT) in out-of-equilibrium systems; in mean field scenarios the corresponding fluctuation-dissipation (FD) plots can, in the limit of long times, be used to define a effective temperature Teff that shares many properties of the true thermodynamic temperature T . We discuss(More)
A new set of data concerning the pattern of suicide in India between 1991-1997 are presented. Suicide rates rose over this period despite a small decline in the Indian suicide rate in 1995 and 1996. It was found that between 1995 and 1997 there was a modest fall in the suicide rates among under 29-year-olds of both sexes, and an increase among those 30(More)
1,5-Diamino-1H-tetrazole (2, DAT) can easily be protonated by reaction with strong mineral acids, yielding the poorly investigated 1,5-diaminotetrazolium nitrate (2a) and perchlorate (2b). A new synthesis for 2 is introduced that avoids lead azide as a hazardous byproduct. The reaction of 1,5-diamino-1H-tetrazole with iodomethane (7a) followed by the(More)

This study investigated the historical trend in resemblance between first-degree relatives for age at death. Data from genealogies of six New England families (N = 13,656) were divided into nine 25 year birth cohorts, 1650-1874, to test the hypothesis that familial influence on human longevity has changed during the past 300 years. Heritability (h2 ) for(More)
The purpose of this prospective clinical study was to assess the rate of healing of periapical bony defects created at the time of endodontic periapical surgery by measuring the densitometric ratio change in periapical osseous tissues, after periapical endodontic surgery was performed, by using or not using Guidor bioresorbable membrane material. Periapical(More)
BACKGROUND This multicenter phase II trial was conducted to analyze the clinical activity and toxicity of the combination of pegylated liposomal doxorubicin and vinorelbine as first-line treatment in elderly patients with metastatic breast cancer. PATIENTS AND METHODS From August 2002 to August 2004, 42 patients with metastatic breast cancer were(More)
Experiment 1 tested the habituation hypothesis of the Verbal Transformation Effect, an auditory illusion in which a repeating verbal stimulus undergoes perceptual transformation, by varying stimulus dimensions which might be expected to retard habituation. Transformations were found to increase as a function of imagery value and word length, failing to(More)
Here we present the synthesis of the new chelating ligands 1-benzothiazol-2-yl-5-(2-hydroxyphenyl)-3-methyl-1H-pyrazole-4-carboxylic acid methyl ester (2a) and 1-(6-chloropyridazin-3-yl)-5-(2-hydroxyphenyl)-3-methyl-1H-pyrazole-4-carboxylic acid methyl ester (2b), obtained in the reaction of 2-methyl-4-oxo-4H-chromene-3-carboxylic acid methyl ester (1) with(More)
The oxide of trivalent antimony is used in the glass-producing industry as a refining agent and as a glass colouring. The batch contains up to 2% Sb2O3, a substance which has shown carcinogenic properties in animal experiments. The internal levels of antimony and lead in blood (SbB and PbB) as well as the excretion with the urine (SbU and PbU) were(More)
We investigate the relation between two-time multispin correlation and response functions in the nonequilibrium critical dynamics of Ising models in d=1 and d=2 spatial dimensions. In these nonequilibrium situations, the fluctuation-dissipation theorem (FDT) is not satisfied. We find FDT "violations" qualitatively similar to those reported in various glassy(More)
