Rhythmic variations in reaction times and evoked potentials

1995

The present work aimed to assess the existence of a regular ultradian cyclicity underlying the variations in amplitude of the N1-P2 component of acoustic EP during a relatively long recording session and investigate its relationship with behavioral measure as RT to the same stimulus. 128 tones were presented to each subject; 128 RTs and the associated EPs to target stimuli were recorded. N1-P2 amplitude has been measured at a single trial level through Woody adaptive filter modified by Wastell. Results showed that there are ultradian rhythmic variations of N1-P2 and RT, with a periodicity from about 5 to 40 min and these variations have similar patterns in the two measures in most of the su…

Co-adsorption of 1,2-dichloroethane and 1-bromo,2-chloroethane on zeolite ZSM-5 from the liquid and vapour phases, using the Myers-Prausnitz-Dubinin …

2002

Abstract The adsorption/co-adsorption of 1,2-dichloroethane (DCA) and 1-bromo,2-chloroethane (BCA) from the vapour and the liquid phases by zeolite ZSM-5 at ambient temperature is reported, using Dubinin's theory and the recent Myers-Prausnitz-Dubinin (MPD) theory. For adsorption from the liquid phase, the activity coefficients in the adsorbed and the liquid states are the same and no selectivity is observed. This is confirmed by the absence of an excess enthalpy of immersion of ZSM-5 into the mixtures. Adsorption from the vapour phase proceeds in two stages, as indicated by double Dubinin-Astakhov (DA) plots. If one considers only the domain of high relative pressure, co-adsorption is desc…

Isobaric Vapor−Liquid Equilibria of Trichloroethylene with 1-Butanol and 2-Butanol at 20 and 100 kPa

1996

Vapor−liquid equilibria for trichloroethylene + 1-butanol, and + 2-butanol are reported at 20 and 100 kPa. The two systems satisfy the point-to-point thermodynamic consistency test. Both systems show a positive deviation from ideality.

Child specific activation in left auditory cortex predicts behavioral performance in inhibition tasks

2020

Sensory processing during development is important for the emerging cognitive skills underlying goal-directed behavior. Yet, it is not known how auditory processing in children is related to their cognitive functions. Here, we utilized combined magneto- and electroencephalographic (M/EEG) measurements to show that child-unique auditory cortical activity at ∼250 ms after auditory stimulation predicts the performance in inhibition tasks. While unaffected by task demands, the amplitude of the left-hemisphere activation pattern was significantly correlated with the variability of behavioral response time. Since this activation pattern is not present in adults, our results suggest divergent brai…

Die Herausbildung von Zufriedenheits-urteilen bei Alternativenbetrachtung

1999

Traditional elements of competitive differentiation are declining. As industries and firms worldwide face increasing competition, slower growth rates, and price pressures, greater attention is being placed on customer satisfaction. However the research in satisfaction never consider alternatives, when customer satisfaction is formed. It has been the approach of this paper to present an extension for this circumstance. Therefor the regret theory, a diversion of the expectation utility theory, is used to explain the phenomena. According to this theory, each outcome has associated with it the evaluation of the difference between the outcome and the outcome that would have been received had a d…

Investment Decision Making and Risk

2013

Abstract The aim of the paper is to present how investment decisions are made and what investment risk is, what role it has in the investment decision. The decision itself is a subjective act, but it is based on both subjective and objective factors. Risk is an important component of every investment, thus it is necessary to analyse it as both, the objective component of the investment, and as the subjective factor of the investment decision making.

Identifying Portfolio-Based Systematic Risk Factors in Equity Markets

2015

Four new prominent asset pricing factors have recently been proposed. We test whether these factors fulfill necessary conditions for qualifying those as risk factors. We show that the investment and betting-against-beta factors fulfill these conditions. However, the profitability and quality factors do not fulfill these conditions pointing towards non-risk-based explanations.

Single umbilical cord blood with or without CD34+ cells from a third-party donor in adults with leukemia

2017

We retrospectively compared the clinical outcomes of adults with acute leukemia who received single-unit umbilical cord blood (UCB) transplantation (sUCBT) (n = 135) or stem cell transplant using coinfusion of a UCB graft with CD34+ cells from a third-party donor (Haplo-Cord) (n = 72) at different institutions within the Grupo Espanol de Trasplante Hematopoyetico. In multivariable analysis, patients in the Haplo-Cord group showed more rapid neutrophil (hazard ratio [HR], 2.3; 95% confidence interval [CI], 1.5-3.3; P < .001) and platelet recovery (HR, 1.6; 95% CI, 1.2-2.3; P = .015) and lower incidence of chronic graft-versus-host disease (GVHD) (relative risk, 0.5; 95% CI, 0.3-0.8; P = .01)…

Therapy-Related Myeloid Neoplasms in Patients With Acute Promyelocytic Leukemia Treated With All-Trans-Retinoic Acid and Anthracycline-Based Chemothe…

2010

Purpose We analyzed the incidence, risk factors, and outcome of therapy-related myeloid neoplasms (t-MNs) in patients with acute promyelocytic leukemia (APL) in first complete remission (CR). Patients and Methods From 1996 to 2008, 1,025 patients with APL were enrolled onto three sequential trials (LPA96, LPA99, and LPA2005) of the Programa Español para el Tratamiento de Enfermedades Hematológicas and received induction and consolidation therapy with all-trans-retinoic acid (ATRA) and anthracycline-based chemotherapy. Results Seventeen of 918 patients who achieved CR developed t-MN (10 with &lt; 20% and seven with ≥ 20% of bone marrow blasts) after a median of 43 months from CR. Partial and…

First experience of the AML-Berlin-Frankfurt-Münster group in pediatric patients with standard-risk acute promyelocytic leukemia treated with arsenic…

2017

Recently, studies in adults with acute promyelocytic leukemia (APL) showed high cure rates in low-risk patients treated with all-trans retinoid acid (ATRA) and arsenic trioxide (ATO), while toxicities were significantly reduced compared to the standard treatment with ATRA and chemotherapy. Here we report about first experience with 11 pediatric patients with low-risk APL treated with ATRA and ATO. All patients stayed in molecular remission. All suffered from hyperleukocytosis. Two patients experienced reversible severe side effects. One suffered from osteonecroses at both femurs, seizures, as well as posterior reversible encephalopathy syndrome, the other patient had an abducens paresis.
