Understanding Perceived Trust to Reduce Regret (2014)

Trust is fundamental for promoting the use of online services, such as e‐commerce or e‐health. Understanding how users perceive trust online is a precondition to create trustworthy marketplaces. In this article, we present a domain‐independent general trust perception model that helps us to understand how users make online trust decisions and how we can help them in making the right decisions, which minimize future regret. We also present the results of a user study describing the weight that different factors in the model (e.g., security , look&feel , and privacy ) have on perceived trust. The study identifies the existence of a positive correlation between the user's knowledge and the importance placed on factors such as security and privacy. This indicates that the impact factors as security and privacy have on perceived trust is higher in users with higher knowledge.
Improvement of start-up and transient characteristics of digital-controlled DC-DC converter using switching-timing predictive PWM control (2010)

This paper proposes a new method for the control of a digital-controlled DC-DC converter. By using this method, both start-up and transient characteristics are improved. The dynamic characteristics at sampling time can be matched to a first-order system. Accordingly, the start-up waveform monotonically increases and the output voltage variation at load transient is small. This method is implemented in a digital signal processor (DSP) and its effectiveness is confirmed in circuit experiments. As a result, the output voltage variation at load transient is as small as 230 mV, which is 7.0% of the rated voltage of 3.3 V, and that at input transient is 43 mV (1.3%). In the start-up characteristics, this method enabled the output voltage to rise to the rated voltage smoothly without overshoot under any conditions.
Electromechanical studies on the inotropic effects of acetylstrophanthidin in ventricular muscle. (1975)

Three phases in the inotropic response of acetyl strophanthidin (AcS) on the electromechnical activity of the frog ventricular myocardium were identified and studied using a single sucrose voltage-clamp technique and other conventional electrophysiological methods. 2. the positive inotropic response of the drug was accompanied by a shift in tension-voltage relation, so that more tension developed with every depolarization step above the mechanical threshold (-50mV). Only at higher drug concentrations or with long exposure times did the mechanical threshold shift to more negative membrane potentials (-60 to-70 mV). 3. In tetrodotoxin-treated muscles AcS produced marked potentiation of twitch tension and an appropriate shift in the tension-voltage relation. 4. the positive inotropic response of the drug was not related to the magnitude of the direction of the fast or slow Na current. 5. in tetrodotoxin-treated ventricular strips the direction or the magnitude of the secondary inward current (ICa or INa) were not related to the inotropic effect of AcS. 6. AcS shortens the action potential markedly during the later stages of its positive inotropic response. When Ca2+ is omitted from the bathing solution AcS not only fails to shorten the action potential, but often prolongs it. 7. The shortening of the action potential in the presence of AcS is accompanied by an increase in the "instantaneous" membrane conductance both at rest and during the time course of the plateau. 8. The decline in the positive inotropic response of the drug was accompanied by the shortening of the action potential. Electrical or chemical prolongation of the action potential restored the full positive inotropic response if the membrane had not depolarized. 9. Membrane depolarization and the development of diastolic tension always occurred at later stages of drug action. Elevation of [Mg+2]degrees to 5 or 10 mM prevented or suppressed the membrane depolarization and the diastolic tension. 10. KCl-induced contractures were potentiated throughout the duration of drug exposure. The tonic component of the contracture tension was markedly elevated especially at later stages of drug action. 11. The experimental evidence suggests that no unitary mechanism could account for multiple actions of acetyl strophanthidin. However, the contributions of the Na pump, the Ca+2 sequestering system, and the K-efflux system to the various stages of drug action are discussed.
Light-Dependent Regulation of <i>DEL1</i> Is Determined by the Antagonistic Action of E2Fb and E2Fc     (2011)

Endoreduplication represents a variation on the cell cycle in which multiple rounds of DNA replication occur without subsequent chromosome separation and cytokinesis, thereby increasing the cellular DNA content. It is known that the DNA ploidy level of cells is controlled by external stimuli such as light; however, limited knowledge is available on how environmental signals regulate the endoreduplication cycle at the molecular level. Previously, we had demonstrated that the conversion from a mitotic cell cycle into an endoreduplication cycle is controlled by the atypical E2F transcription factor, DP-E2F-LIKE1 (DEL1), that represses the endocycle onset. Here, the Arabidopsis (Arabidopsis thaliana) DEL1 gene was identified as a transcriptional target of the classical E2Fb and E2Fc transcription factors that antagonistically control its transcript levels through competition for a single E2F cis-acting binding site. In accordance with the reported opposite effects of light on the protein levels of E2Fb and E2Fc, DEL1 transcription depended on the light regime. Strikingly, modified DEL1 expression levels uncoupled the link between light and endoreduplication in hypocotyls, implying that DEL1 acts as a regulatory connection between endocycle control and the photomorphogenic response.

The Barkhausen noise is calculated for ferromagnetic cores used in magnetic amplifiers. The method of analysis follows that used in the analysis of the shot effect. The signal-to-noise ratio for a typical magnetic amplifier circuit is calculated and compared with experiment.
Oxidation of Silicon and Silicon Carbide in Ozone‐Containing Atmospheres at 973 K (2002)

The oxidation behavior of a silicon wafer, chemically vapor‐deposited SiC, and single‐crystal SiC was investigated in an oxygen—2%–7% ozone gas mixture at 973 K. The thickness of the oxide film that formed during oxidation was measured by ellipsometry. The oxidation rates in the ozone‐containing atmosphere were much higher than those in a pure oxygen atmosphere. The parabolic oxidation kinetics were observed for both silicon and SiC. The parabolic rate constants varied linearly with the ozone‐gas partial pressure. Inward diffusion of atomic oxygen formed by the dissociation of ozone gas through the SiO 2 film apparently was the rate‐controlling process.
Tetra[2,3-thienylene]:  A Building Block for Single-Molecule Electromechanical Actuators (2002)

Tetra(2,3-thienylene) is a thiophene-fused [8]annulene capable of undergoing redox-induced dimensional changes. The feasibility of efficiently translating this intrinsic function into a single polymeric electromechanical actuator is investigated by both experiment and density functional theory (B3LYP 6-31G[d,p]). A study of tetra(2,3-thienylene) and its homodimer reveal that redox-induced conformational change is conserved upon dimerization, a result that implicates similar behavior in the corresponding polymer. Theoretical predictions yield a maximum redox-induced dimensional change of 5.92% per repeat unit for the homodimer. Cyclic voltammetry reveals complete reversibility for the corresponding redox cycle. The latter two facts establish tetra(2,3-thienylene) as a suitable building block for single-molecule electromechanical actuators.
Factors affecting the suitability of glass jars for heating in microwave ovens. Comparison with plastic jars and paper board tubs (1993)

Abstract The suitability of glass jars for heating in microwave ovens was studied. The aim of the study was to determine the effects of the type of foodstuff, the shape and the volume of the jars and the heating conditions (e.g. the type of microwave oven and the initial temperature) on the functionality and durability of glass jars heated in microwave ovens and on the heating result. Moreover, the behaviour of glass jars was compared with that of paperboard and plastic containers. A total of 243 glass jars were heated during the the tests. None of the jars were broken, even when the contents were initially frozen or when all the jars were placed on a cold surface immediately after heating. However, splashing of the contents and/or jumping of the jar with a resulting loud clatter represented a major problem. Jumping of the jars and splashing of the contents depended on both the recipe and the consistency of the food and the shape of the jar, but less on the packaging material, the initial temperature or the heating time. The plastic and board containers also jumped and food splashed out of them. If glass jars or cylindrical/jar‐like packages are to be used for the packaging of microwaveable foods, both the recipe of the foodstuffs and the shape of the jars need to be developed further.
Using Genetic Algorithms to Solve the Tactical Fixed Interval Scheduling Problem (2000)

Discrete optimization problems are usually NP hard. The structural characteristics of these problems significantly dictate the solution landscape. In this paper, we explore a structured approach to solving these kinds of problems. We use a reinforcement learning system to adaptively learn the structural characteristics of the problem, hereby decomposing the problem into several subproblems. Based on these structural characteristics, we develop a Genetic Algorithm by using structural operations to recombine these subproblems together to solve the problem. The reinforcement learning system directs the GA. We test our algorithm on the Tactical Fixed Interval Scheduling Problem(TFISP) which is the problem of determining the minimum number of parallel non-identical machine such that a feasible schedule exists for a given set of jobs. This work continues our work in exploiting structure for optimization(Zhong & Santos 1999).
Two novel DRB alleles detected by PCR‐SSO and confirmed by sequencing: DRB1*0317 and DRB3*0210 (2000)

We here describe two new DRB alleles (DRB1*0317 and DRB3*0210) which were detected by polymerase chain reaction using sequence-specific oligonucleotides (PCR-SSO) and confirmed by direct sequencing. The exon 2 sequence of DRB1*0317 is the result of an intergenic recombination event yielding a hybrid allele between 5'DRB1 and 3' DRB3 sequences with the recombination breakpoint located between codons 39-51. The new DRB3*0210 allele is closest related to DRB3*02021 except for a single nucleotide position at codon 51. Here, the sequence AGG at codon 51 which was a group-specific motif for all DRB3*02 alleles described previously, is replaced by the DRB consensus sequence ACG.

Local and bulk 13C hyperpolarization in nitrogen-vacancy-centred diamonds at variable fields and orientations (2015)

Polarizing nuclear spins is of fundamental importance in biology, chemistry and physics. Methods for hyperpolarizing (13)C nuclei from free electrons in bulk usually demand operation at cryogenic temperatures. Room temperature approaches targeting diamonds with nitrogen-vacancy centres could alleviate this need; however, hitherto proposed strategies lack generality as they demand stringent conditions on the strength and/or alignment of the magnetic field. We report here an approach for achieving efficient electron-(13)C spin-alignment transfers, compatible with a broad range of magnetic field strengths and field orientations with respect to the diamond crystal. This versatility results from combining coherent microwave- and incoherent laser-induced transitions between selected energy states of the coupled electron-nuclear spin manifold. (13)C-detected nuclear magnetic resonance experiments demonstrate that this hyperpolarization can be transferred via first-shell or via distant (13)Cs throughout the nuclear bulk ensemble. This method opens new perspectives for applications of diamond nitrogen-vacancy centres in nuclear magnetic resonance, and in quantum information processing.
Practical One‐Pot Preparation of Magnesium Di(hetero)aryl‐ and Magnesium Dialkenylboronates for Suzuki–Miyaura Cross‐Coupling Reactions (2011)

Mg for B: An atom-economical one-pot synthesis by direct magnesium insertion in the presence of B(OBu)3 and LiCl allows a broad range of functionalized (hetero)aryl and alkenyl bromides to be converted into magnesium diorganoboronates 2, which undergo Suzuki–Miyaura cross-coupling reactions with various aryl (pseudo)halides (see scheme). Both aryl groups of 2 are transferred and furnish the products in good to excellent yields. Detailed facts of importance to specialist readers are published as ”Supporting Information”.

Comparative Sequence Analysis of the Ghd7 Orthologous Regions Revealed Movement of Ghd7 in the Grass Genomes (2012)

Ghd7 is an important rice gene that has a major effect on several agronomic traits, including yield. To reveal the origin of Ghd7 and sequence evolution of this locus, we performed a comparative sequence analysis of the Ghd7 orthologous regions from ten diploid Oryza species, Brachypodium distachyon, sorghum and maize. Sequence analysis demonstrated high gene collinearity across the genus Oryza and a disruption of collinearity among non-Oryza species. In particular, Ghd7 was not present in orthologous positions except in Oryza species. The Ghd7 regions were found to have low gene densities and high contents of repetitive elements, and that the sizes of orthologous regions varied tremendously. The large transposable element contents resulted in a high frequency of pseudogenization and gene movement events surrounding the Ghd7 loci. Annotation information and cytological experiments have indicated that Ghd7 is a heterochromatic gene. Ghd7 orthologs were identified in B. distachyon, sorghum and maize by phylogenetic analysis; however, the positions of orthologous genes differed dramatically as a consequence of gene movements in grasses. Rather, we identified sequence remnants of gene movement of Ghd7 mediated by illegitimate recombination in the B. distachyon genome.
FaceSync: A Linear Operator for Measuring Synchronization of Video Facial Images and Audio Tracks (2000)

FaceSync is an optimal linear algorithm that finds the degree of synchronization between the audio and image recordings of a human speaker. Using canonical correlation, it finds the best direction to combine all the audio and image data, projecting them onto a single axis. FaceSync uses Pearson's correlation to measure the degree of synchronization between the audio and image data. We derive the optimal linear transform to combine the audio and visual information and describe an implementation that avoids the numerical problems caused by computing the correlation matrices.

Changes in expression of the prolactin and growth hormone gene during different reproductive stages in the pituitary gland of turkeys (1997)

The changes in levels of prolactin (PRL) and growth hormone (GH) in plasma and the pituitary gland and their transcripts were measured in turkey hens at different physiological stages by radioimmunoassay and dot blot hybridization analysis, respectively. The levels of tPRL mRNA in the pituitary gland increased from those of the immature group to the egg-laying group, reaching a maximum during the incubation and a minimum during the moulting stages. Changes in pituitary levels of PRL and PRL mRNA followed a similar trend and consequently were highly correlated (r2 = 0.83), whereas a significant but lower correlation was observed between circulating and pituitary levels (r2 = 0.62). Less significant changes were measured for tGH mRNA, with maximum and minimum levels measured in the pituitaries of egg-laying and non-laying hens, respectively. These data suggest that although changes in concentration of PRL are correlated with the reproductive stage of the turkey hen, coordinate changes in levels of GH are not.
A Multiresponsive Anisotropic Hydrogel with Macroscopic 3D Complex Deformations (2016)

As one of the most promising smart materials, stimuli‐responsive polymer hydrogels (SPHs) can reversibly change volume or shape in response to external stimuli. They thus have shown promising applications in many fields. While considerable progress of 2D deformation of SPHs has been achieved, the realization of 3D or even more complex deformation still remains a significant challenge. Here, a general strategy towards designing multiresponsive, macroscopically anisotropic SPHs (MA‐SPHs) with the ability of 3D complex deformations is reported. Through a local UV‐reduction of graphene oxide sheets (GOs) with a patterned fashion in the GO‐poly( N ‐isopropylacrylamide) (GO‐PNIPAM) composite hydrogel sheet, MA‐SPHs can be achieved after the introduction of a second poly(methylacrylic acid) network in the unreduced part of GO‐PNIPAM hydrogel sheet. The resulting 3D MA‐SPHs can provide remote‐controllable light‐driven, as well as thermo‐, pH‐, and ionic strength‐triggered multiresponsive 3D complex deformations. Approaches in this study may provide new insights in designing and fabricating intelligent soft materials for bioinspired applications.
Revolutionary nanocomposite materials to enable space systems in the 21/sup st/ century (2002)

Current estimates for launching payloads into space orbit stand at $10,000/lb ($22,000/kg). Significant weight, and hence cost, reductions can be realized with the use of organic materials, but such materials tend to perform very poorly in the harsh space environment. Organic polymers with uniformly dispersed nanoscale inorganic precursors may enable these materials to withstand the harsh space environment and be used as critical weight-reduction materials on current and future space systems. Nanocomposites, as these types of materials are often referred to, have received much attention over the past decade as scientists search for ways to enhance the properties of engineering polymers while retaining their processing ease. Unlike traditional filled polymer systems, nanocomposites require relatively low dispersant loadings (/spl sim/2 wt%) to achieve significant property enhancements. Some of these enhancements include increased modulus, increased gas barrier, increased thermal performance, increased atomic oxygen resistance, resistance to small molecule permeation and improved ablative performance. As a result of these enhancements, nanocomposites have the potential to play a significant role in future space systems. Launch vehicles would greatly benefit from appropriately designed nanocomposites that could provide improved barrier properties and gradient morphologies enabling linerless composite cryogenic fuel tanks. Self-rigidizing, self-passivating nanocomposite materials could be used to construct space vehicle components that are both highly resistant to space-borne particles and resistant to degradation from electromagnetic radiation, while reducing the overall weight of the spacecraft. Nanocomposite materials also offer the unique opportunity for improved tailorability of physical and structural properties such as the coefficient of thermal expansion, which would be especially useful in constructing large aperture telescopes and antennas using inflatable membranes.
Influence of GaN Stress on Threshold Voltage Shift in AlGaN/GaN High-Electron-Mobility Transistors on Si under Off-State Electrical Bias (2013)

The change in threshold voltage (Vth) in AlGaN/GaN high-electron-mobility transistors (HEMTs) on Si occurs during off-state bias stress. Raman spectroscopy shows that the GaN strain/stress changes with the increase in buffer and i-GaN thicknesses. Our results revealed that there is a strong correlation between the Vth shift and GaN strain/stress. The Vth shifts positively and negatively, respectively, for biaxial tensile and compressive strains. We observed minimal device degradation with the negligible Vth shift before and after off-state bias stress for the strain relieved sample. The results illustrate the importance of GaN strain/stress for the degradation and reliability of AlGaN/GaN HEMTs.
Bandwidth allocation and routing in ISDN's (1984)

The goal of communications network design is to satisfy user requirements with the minimum amount of investment. This paper presents a method for the optimal design of ISDN's. First, three multiplexing systems that allow the integration of circuit- and packetswitching traffic are described. Then, a key design problem - bandwidth allocation and routing for integrated networks - is formulated, and efficient methods for its solution are presented.
Multichannel balanced detection of ultrashort THz pulses (2007)

We present ID electrooptical sampling of ultrashort THz pulses with a multichannel balanced detector. Together with lock-in technique, it combines the advantage of a high signal to noise ratio (SNR) with the fast acquisition time of multichannel detection. The THz beam is focussed to a line on the sample and imaged to a line at the electrootpical crystal again. The probe beam is also focussed to a line at the electrooptical crystal and imaged to the multichannel balanced detector.
