EFFECTS OF SELF‐STUDY OF TEST FAMILIARIZATION MATERIALS FOR THE ANALYTICAL SECTION OF THE GRE APTITUDE TEST (1982)

ABSTRACT An experimental study was conducted to (a) provide further information on the possible differential susceptibility to special preparation of three GRE analytical item types, (b) determine whether candidates' self‐study of test familiarization materials might result in analytical ability score improvements comparable to those resulting from formal instructional intervention, and (c) ascertain which components of the special preparation were most effective. To provide this information various sets of test preparation materials (practice tests, explanations of answers to practice questions, and suggested strategies for approaching each analytical item type) were mailed to random samples of GRE candidates approximately four to five weeks before the test date. Candidates' use of each set of materials was manipulated by encouraging random samples of candidates to study the materials. Comparisons of the subsequent GRE scores of the various groups of candidates (a) confirmed the susceptibility to special preparation of two of the analytical item types (analysis of explanations and logical diagrams), (b) suggested little susceptibility for either of the two subtypes of the third item type (analytical reasoning), (c) provided strong evidence that candidates can undertake effective self‐preparation for “coachable” item types like the ones studied here, (d) pointed to some components of test preparation (e.g., extra test practice) as more effective than others, and (e) strongly suggested that, even more than the particular kind of preparation undertaken, being engaged in some preparation is necessary for successful performance on these item types.
First direct kinetic study of isotopic enrichment of ozone (1995)

The formation kinetics of ozone has been studied using isotopes and pulse radiolysis combined with time‐resolved UV absorption spectroscopy. An enhancement of (9.8±2.6)% was found for the rate constant for the reaction of 18 O with 18 O 18 O relative to that for the 16 O+ 16 O 16 O reaction. The average formation rate for unsymmetric 18 O 16 O 16 O and 16 O 18 O 18 O from O 2 and 18 O 18 O respectively was enhanced by (14.7±2.8)%. For the formation of a mixture of symmetric and unsymmetric ozone species from O 18 O the enhancement was (3.6±2.4)%. This leads to the conclusion that both mass and symmetry affect the rate constant for formation of isotopic ozone. The results are compared with recent enhancement studies from the literature, and an apparent conflict is discussed.
O5‐05‐03: The relationship between cognition and everyday functioning: Let's pay attention! (2012)

In a memory clinic-setting, cognitive functioning as measured on neuropsychological tests is generally assumed to reflect patients everyday functioning. However, previous studies showed that neuropsychological tests can only partly explain everyday performance. Informant reports on everyday functioning provide relevant additional information to the clinician. In early dementia, reports of ‘instrumental activities of daily living’ (IADL) are of particular importance, as these activities are affected early in the disease course. The Amsterdam IADL Questionnaire® was previously found to be a reliable instrument and in this validation study we investigate the relationship between the Amsterdam IADL Questionnaire and neuropsychological test performance. Patients who visited the Alzheimer Center of the VU University Medical Center for dementia screening completed a standard neuropsychological test battery including tests aimed at measuring attention, executive functioning, memory and visuospatial functioning. Informants of patients completed the computer-based Amsterdam IADL Questionnaire. Confirmatory item factor analysis was used to investigate the factor structure of the neuropsychological tests. Structural equation modeling was used to investigate the relationships between the cognitive domains and IADL. A total of 246 patients were included in the study, of which 97 (39.4%) received a diagnosis of dementia. Six models were tested to find an adequate model of cognitive domains. The final model consisted of three cognitive domains; attention/executive, memory and visuospatial functioning, and had a satisfactory fit (RMSEA = .077, CFI = .949, SRMR = .044). The structural model with IADL as latent variable and the cognitive domains as measured variables showed that attention/executive was associated with complex everyday functioning (standardized B = -.348, SE = .128, P = .007). In this study we found that of three general cognitive domains, attention/executive functioning is most strongly related to complex everyday functioning. Memory and visuospatial functioning were not related to everyday functioning, indicating that precautions must be taken in generalizing neuropsychological test results to everyday performance.
Global asymptotic stabilisation of an active mass damper for a flexible beam. (1999)

In this paper, a finite dimensional approximated model of a mechanical system constituted by a vertical heavy flexible beam with lumped masses placed along the beam and a mobile mass located at the tip, is proposed; such a model is parametric in the approximation order, so that a prescribed accuracy in the representation of the actual system can be easily obtained with the proposed model. The system itself can be understood as a simple representation of a building subject to transverse vibrations, whose vibrating modes are damped by a control action performed at the top by means of a mobile mass. A simple PD control law, which requires only the measurement of the position and velocity of the mobile mass with respect to the end-point of the beam, is shown to globally asymptotically stabilise all the flexible modes considered in the approximated model, regardless of the chosen approximation order, under a technical assumption that is satisfied in many cases of practical interest. Simulation runs confirm the effectiveness of the proposed control law in achieving both position regulation of the mobile mass and vibration control.
Prioritized routing and burst segmentation for QoS in optical burst-switched networks (2002)

In this paper we apply the concepts of burst segmentation and priority-based deflection routing algorithms to provide differentiated services in optical burst-switched networks. The high-priority bursts have significantly lower losses and delay then the low-priority bursts, and the policies which incorporate deflection tend to perform better than the policies with limited deflection or no deflection.
METAL CHELATES OF MERCAPTOSUCCINIC AND $alpha$,$alpha$-DIMERCAPTOSUCCINIC ACIDS (1964)

The interactions of metal ions with alpha -mercaptosuccinic acid and with alpha , alpha '-dimercaptosuccinic acid with various metal ions were determined by potentiometric measurement of hydrogen ion concentration. With mercaptosuccinic acid, evidence is presented for the formation of 1: 1 and 2: 1 ligand-metal complexes as well as a zinc hydroxo complex. With alpha , alpha '- dimercaptocuccinic acid, the existence of 1: 1 and 2: 1 complexes was established, together with various protonated and hydroxo complexes. Equilibrium constants are reported for soluble metal chelate systems and the equilibrium data are interpreted in terms of probable structure of the complexes formed. (auth)
First Clinical Experience With Targeted REnal Nerve Demodulation (TREND-1) Using a Neurotropic Agent for the Treatment of Sympathetic Hypertension. (2017)

Treatment of hypertension using local administration of NW2013 near renal nerves appears to be feasible and safe. Large, controlled, randomized, and blinded clinical studies with monitoring of patient compliance to daily oral medication are recommended to further establish the efficacy of this novel treatment.
RAPID DIAGNOSIS OF GENITOURINARY TUBERCULOSIS BY POLYMERASE CHAIN REACTION AND NON-RADIOACTIVE DNA HYBRIDIZATION (2000)

The high sensitivity and specificity in addition to the potential for rapid detection of mycobacteria, makes this test a useful tool in the clinical management of mycobacterial infection in urine. Urine specimens may contain M. tuberculosis and/or other mycobacteria; therefore, there are advantages in using genus-specific primers in parallel with species-specific primers in PCR assay.
Production of bone resorbing activity in poorly differentiated monocytic malignancy (1978)

A patient with poorly differentiated monocytic malignancy had extensive lytic lesions of bone and hypercalcemia. The patient's bone margins showed little evidence of osteoclast activity. Serum parathormone concentrations were slightly increased relative to the degree of hypercalcemia, consistent with impaired renal function. Serum concentrations of the relevant prostaglandins were normal. Supernatant medium from cultured tumor cells caused prominent bone resorption in vitro. The studies on this patient provide evidence that malignant cells of the monocyte-macrophage line are capable of direct bone resorption.
Recombinant growth hormone enhances muscle myosin heavy-chain mRNA accumulation and amino acid accrual in humans. (1989)

A potentially lethal complication of trauma, malignancy, and infection is a progressive erosion of muscle protein mass that is not readily reversed by nutritional support. Growth hormone is capable of improving total body nitrogen balance, but its role in myofibrillar protein synthesis in humans is unknown. The acute, in situ muscle protein response to an infusion of methionyl human growth hormone was investigated in the limbs of nutritionally depleted subjects during a period of intravenous refeeding. A 6-hr methionyl growth hormone infusion achieved steady-state serum levels comparable to normal physiologic peaks and was associated with a significant increase in limb amino acid uptake, without a change in body amino acid oxidation. Myosin heavy-chain mRNA levels, measured by quantitative dot blot hybridization, were also significantly elevated after growth hormone administration. The data indicate that methionyl growth hormone can induce intracellular amino acid accrual and increased levels of myofibrillar protein mRNA during hospitalized nutritional support and suggest growth hormone to be a potential therapy of lean body wasting.
C<SUB>4</SUB>-like Plants Derived from a Cross (<i>Atriplex rosea</i> (C<SUB>4</SUB>)×<i>A. patula</i> (C<SUB>3</SUB>))×<i>A. rosea</i> (1988)

To analyse the genetic aspects of C3 and C4 photosynthetic systems, the photosynthetic charcacteristics of the progenies derived from a backcross, (Atriplex rosea (C4, 2 n=18, 2x)xA.patula (C3, 2n=36, 4x))xA, rosea, were investigated. Out of three plants derived from the backcross, two showed C4-Iike traits based on the C02 compensation point and δ13C values as well as enzyme analysis and leaf anatomy. Another plant showed C3-like characteristics. The descendants of these plants were segregated into three discrete morphofogical types ; p-type plants which were similar to A. patula ; d-type plants which were dwarf with dark green leaves ; and r-type plants which resembled A.rosea but exhibited a highly branching habit. The isozyme patterns of the leaves of the pand d-types were similar to those of A.patula, while th.e isozyme patterns of the r-type were either similar to those of A.rosea or different from the parental patterns. Based on anatomical, photosynthetic and enzymological observations, the p- and d-types showed C3-like traits, whereas the r-type C4-like ones. Chromosome analysis from the root tips revealed a 2n=36 number in the p- and d-types and a 2n=18 one in the r-type. It is suggested that the expression of C4 photosynthesis is affected by the dose of the genome of the C4 species and that the genes related to C4 photosynthesis tend to be inherited as a group in the interspecific hybrids.
Empirical model of atomic nitrogen in the upper thermosphere (1977)

Atomic nitrogen number densities in the upper thermosphere measured by the open source neutral mass spectrometer (OSS) on Atmosphere Explorer-C during 1974 and part of 1975 have been used to construct a global empirical model at an altitude of 375 km based on a spherical harmonic expansion. The most evident features of the model are large diurnal and seasonal variations of atomic nitrogen and only a moderate and latitude-dependent density increase during periods of geomagnetic activity. The model also suggests the presence of a substantial semiannual variation and of nighttime minima at mid-latitudes. Maximum and minimum N number densities at 375 km for periods of low solar activity are 3.6 × 106 cm−3 at 1500 LST (local solar time) and low latitude in the summer hemisphere and 1.5 × 105 cm−3 at 0200 LST at mid-latitudes in the winter hemisphere. The amplitude of the diurnal variation at equatorial latitudes is about a factor of 8.
Total Syntheses of (2<i>S</i>)-Antafumicins A and B (1994)

To clarify the absolute configurations of antafumicins A and B, which are antifungal substances from Aspergillus niger NH-401, the total synthesis of (2S)-antafumicins was accomplished by starting from (S)-malic acid in 12 steps. Based upon the physicochemical data of the synthetic samples, the absolute configurations of naturally occurring antafumicins A and B were determined as (2R,4S)- and (2R,4R)-4-(3-acetyl-2,6-dihydroxyphenyl)-2-methoxy-4-butanolide, respectively.

Serum hepcidin at mid‐gestation is not associated with neonatal hepcidin or maternal obesity among pregnant adolescents (2011)

Hepcidin is a systemic regulator of iron (Fe) homeostasis whose synthesis is increased in inflammatory conditions such as obesity. To assess determinants of hepcidin in pregnant adolescents, maternal and cord blood were obtained from a group of 93 pregnant teens (17.1 ± 1.1 y with prepregnancy BMI from 17.0 – 41.5 kg/m2). Serum ferritin (SF), transferrin receptor (sTfR) and hepcidin concentrations (by C-ELISA) were measured at mid-gestation (26.3 ± 3.5 wks) and in cord blood at delivery (39.8 ± 1.3 wks). Maternal weight gain across pregnancy averaged 17.4 ± 7.3 kg and ranged from −2.2 – 39.5 kg. Maternal hepcidin was significantly lower than neonatal hepcidin (32.1 ± 28.3 vs.132 ± 95.9 ng/mL, p<0.0001) but the two were not significantly correlated. Maternal hepcidin was significantly lower in adolescents with tissue Fe depletion (sTfR >8.5 mg/dL; p=0.009, n=78) and depleted Fe stores (ferritin < 20 ug/L; p=0.01, n=77) at mid-gestation. Unlike observations among non-pregnant women, no significant relationship was evident between maternal hepcidin and prepregnancy BMI or between those with a BMI < 30 vs.> 30 kg/m2 at term. The high iron demands of the pregnant adolescent and her developing fetus may override the effect of inflammation on hepcidin during pregnancy. USDA: 2005–35200 & 2008–0857

Dynamic LDPC codes for nanoscale memory with varying fault arrival rates (2011)

Modern state-of-the-art nanodevices exhibit remarkable electronic properties, but the current assembly techniques yield very high defect and fault rates. Static errors can be addressed at fabrication time by testing and reconfiguration, but soft errors are problematic since their arrival rates are expected to vary over the lifetime of a part. Usual designs consider error correcting codes that tolerate the maximum failure rate expected over the entire lifetime. In this paper, we propose using a special variant of low-density parity codes (LDPCs) - Euclidean Geometry LDPC (EG-LDPC) codes - to enable dynamic changes in the level of fault tolerance. EG-LDPC codes have high error correcting ability (for large words they can approach the optimal Shannon limit) and they are sparse (circuit implementation requires small fan-in). In addition, a special property of EG-LDPC codes enables us to dynamically adjust the error correcting capacity for improved system performance (e.g., lower power consumption) during periods of expected low fault arrival rate. We present a system architecture for nanomemory based on nanoPLA building blocks using EG-LDPCs, where the encoder/decoder could also have faults, and analyze the fault detection and correction capabilities considering dynamic fault tolerance.
Utilization of high performance fiber-reinforced micro-concrete as a repair material (2008)

Problems of early degradation, reduced service life and repair costs that overhead the price of structure itself, have resulted in development of new materials and technologies for repair of concrete structures. Recent results show that High Performance Fiber-Reinforced Micro Concrete (HPFRMC), used as repair material, has very good properties concerning stability, serviceability and durability. For that reason there has been a growing interest in the use of HPFRMC for repair and rehabilitation of concrete structures. The aim of this research was to evaluate the efficiency of high performance fiber-reinforced micro-concrete as a repair material when applied on concrete beam. During the research testing of compressive strength, flexural strength, modulus of elasticity and toughness has been performed on concrete beams repaired with high performance fiber-reinforced micro-concrete and cement mortar. Results of this research have proven that the use of high performance fiber-reinforced micro-concrete as repair material has both economical and technical advantages.

Performance evaluation of a real time traffic sign recognition system (2008)

Traffic sign recognition has been a very active research topic for many years now. However, during this time of intensive research, no common evaluation methodology has been established. This paper explains in detail, how we evaluated our real time video-based traffic sign recognition system and thus may serve as a building block towards establishing a commonly accepted evaluation methodology. The proposed evaluation methods are taken from the visual surveillance research community, which was very active in evaluation techniques during the recent years.
