The Influence of Starch Structure on Glycogen Resynthesis and Subsequent Cycling Performance (1996)

The present study was designed to evaluate the influence of starch structure on muscle glycogen resynthesis and cycling performance. Eight male cyclists (22 +/- 1 yr) completed an exercise protocol (DP) to decrease vastus lateralis glycogen concentration. This exercise consisted of 60 min cycling at 75% VO2max, followed by six 1-min sprints at approximately 125% VO2max with 1 min rest intervals. In the 12 hr after the exercise each subject consumed approximately 3000 kcal (65:20:15% carbohydrate, fat and protein). All of the carbohydrate (CHO) consumed was derived from one of four solutions; 1) glucose, 2) maltodextrin (glucose polymer), 3) waxy starch (100% amylopectin), or 4) resistant starch (100% amylose). Muscle biopsies were taken from the vastus lateralis muscle after DP and 24 hr later to determine glycogen concentrations. A 30 min cycling time trial (TT) was performed following the 24 hr post-DP muscle biopsy to examine the influence of the feeding regimen on total work output. The post-DP glycogen concentrations were similar among the four trials, ranging from 220.3 +/- 29.2 to 264 +/- 48.3 mmol.kg-1 dry weight (d.w.) muscle. Twenty-four hours after DP, muscle glycogen concentration had increased less (p < 0.05) in the resistant starch trial (+90.8 +/- 12.8 mmol.kg-1 d.w.) than in the glucose (+197.7 +/- 31.6 mmol.kg-1 d.w.), maltodextrin (+136.7 +/- 24.5 mmol.kg-1 d.w.) and waxy starch (+171.8 +/- 37.1 mmol.kg-1 d.w.) trials. There were no differences in total work output during the TT, or blood lactate concentration immediately following the TT in any of the CHO trials. In summary, glycogen resynthesis was attenuated following ingestion of starch with a high amylose content, relative to amylopectin or glucose; however, short duration time trial performance was unaffected.
Transient Response of 3-D Multi-Channel Nanowire MOSFETs Submitted to Heavy Ion Irradiation: a 3-D Simulation Study (2009)

The single-event response of 3-D Multi-Channel nanowire MOSFETs (MCFET) is investigated using 3-D numerical simulation. The variation with time of the main internal parameters (electrostatic potential and electron density) of the MCFET after the ion strike is analyzed in detail. The drain current transients and collected charge depend on the ion strike location, direction, and track radius. The lateral spacing between adjacent nanowire stacks is found to be a key-parameter in the analysis of the worst case location of the ion strike.
Work and Flexible Automation in Britain: A Review of Developments and Possibilities (1988)

The convergence of information technologies into flexible automation systems underlies theories of both the upgrading and deskilling of jobs in manufacturing. Relevant empirical studies are analysed using a distinction between the system-integration and operational flexibility dimensions of the technologies. The review shows that their use in Britain is still limited and that the present pattern of accompanying work roles and occupational statuses includes both enhancement and degradation of work, even within the same occupation. The social and technological patterns are attributed to: organisational constraints on unions, the financial priorities of enterprises operating within a dual industrial structure, and state policies' emphasis on the cost-saving gains of the advanced system-integration forms of technology.
Interactive Virtual Terrain Generation using Augmented Reality Markers (2013)

This paper presents an application that allows the generation of virtual terrains interactively, using augmented reality markers. This application also allows the user to navigate in the generated virtual environment. To demonstrate how the process is done, a terrain generation scenario was chosen. Virtual objects were augmented using markers and the detection is done through the ARToolKit framework. A particle system was used to simulate deformation to better incorporate the needs of terrain generation. The deformation itself follows an interparticle force between the particles attached to a movable physical marker and the particles attached to a fixed multi-marker representing the mesh. A viscous force is also used to generate a plastic material effect ensuring permanent deformation. The resulting application although conceptually simple and easy to use, can produce an immersive output environment that the user can freely navigate.
Dynamic Behavior of a Class of Photovoltaic Power Systems (1983)

An important consideration in the operation of grid connected photovoltaic power systems is a means of adjusting the photovoltaic array voltage so that maximum output power is achieved for the given atmospheric conditions. The dynamic behiavior of a specific photovoltaic power system which utilizes the well known perturb and observe method of power tracking is examined. Using measured insolation data, it is demonstrated that the perturb and observe method of control migrates considerably from peak power whenever the insolation varies randomly as a result of cloud cover. An alternate method of power tracking is also examined. It is shown that the photovoltaic power system, utilizing the proposed method of power tracking, is able to track accurately peak power conditions during periods of randomly varying insolation.
3-Hydroxyisobutyrate Dehydrogenase from<i>Pseudomonas putida</i>E23: Purification and Characterization (1996)

The NAD(+)-dependent 3-hydroxyisobutyrate dehydrogenase [EC 1.1.1.31] was purified to homogeneity from Pseudomonas putida E23. The enzyme was a tetramer (molecular mass, 120 kDa) consisted of identical subunits (molecular mass, 30 kDa). The enzyme was specific for NAD+ (Km, 0.44 mM). The maximal activity was obtained at about pH 10. The enzyme was specific for the L-isomer of 3-hydroxyisobutyrate. In addition to L-3-hydroxyisobutyrate, L-serine, 2-methyl-DL-serine, and 3-hydroxypropionate were substrates. The Km for L-3-hydroxyisobutyrate, L-serine, 2-methyl-DL-serine, and 3-hydroxypropionate were 0.12, 18, 44, and 83 mM, respectively. The enzyme was inhibited by p-chloromercuribenzoate, HgCl2, and AgNO3, but not by EDTA, alpha,alpha'-dipyridyl, and o-phenanthroline. The N-terminal 26 amino acid sequence was compared with the sequences deduced from the enzyme genes of rat liver and Pseudomonas aeruginosa.
Factors influencing the isolation process of islets of Langerhans. (1990)

Determination of collagenase and proteolytic activities and slabgel electrophoresis of collagenase preparations obtained from different suppliers reveals a highly variable content of collagenase, proteolytic activities and other components. The electrophoresis pattern can help to select collagenase preparations with a low content of impurities suitable for islet isolation. During islet isolation the exocrine tissue releases large amounts of proteolytic activities into the digestion medium, which decreases islet yield. Addition of 10% albumin to the digestion medium strongly suppresses the release of proteolytic activity and increases the number of islets obtained. Addition of both albumin and trypsin inhibitors further increases not only the number of islets, but also the total volume of islet tissue obtained. The islet isolation process is not critically dependent on the pH in the range 6.2 to 8.0 and only marginally dependent on the calcium concentration.
Drug-Induced Nephrotoxicity and Its Biomarkers (2012)

Nephrotoxicity occurs when kidney-specific detoxification and excretion do not work properly due to the damage or destruction of kidney function by exogenous or endogenous toxicants. Exposure to drugs often results in toxicity in kidney which represents the major control system maintaining homeostasis of body and thus is especially susceptible to xenobiotics. Understanding the toxic mechanisms for nephrotoxicity provides useful information on the development of drugs with therapeutic benefi ts with reduced side effects. Mechanisms for drug-induced nephrotoxicity include changes in glomerular hemodynamics, tubular cell toxicity, inflammation, crystal nephropathy, rhabdomyolysis, and thrombotic microangiopathy. Biomarkers have been identifi ed for the assessment of nephrotoxicity. The discovery and development of novel biomarkers that can diagnose kidney damage earlier and more accurately are needed for effective prevention of drug-induced nephrotoxicity. Although some of them fail to confer specificity and sensitivity, several promising candidates of biomarkers were recently proved for assessment of nephrotoxicity. In this review, we summarize mechanisms of drug-induced nephrotoxicity and present the list of drugs that cause nephrotoxicity and biomarkers that can be used for early assessment of nephrotoxicity.
4-Octyl itaconate inhibits aerobic glycolysis by targeting GAPDH to exert anti-inflammatory effects (2019)

Activated macrophages switch from oxidative phosphorylation to aerobic glycolysis, similar to the Warburg effect, presenting a potential therapeutic target in inflammatory disease. The endogenous metabolite itaconate has been reported to regulate macrophage function, but its precise mechanism is not clear. Here, we show that 4-octyl itaconate (4-OI, a cell-permeable itaconate derivative) directly alkylates cysteine residue 22 on the glycolytic enzyme GAPDH and decreases its enzyme activity. Glycolytic flux analysis by U<sup>13</sup>C glucose tracing provides evidence that 4-OI blocks glycolytic flux at GAPDH. 4-OI thereby downregulates aerobic glycolysis in activated macrophages, which is required for its anti-inflammatory effects. The anti-inflammatory effects of 4-OI are replicated by heptelidic acid, 2-DG and reversed by increasing wild-type (but not C22A mutant) GAPDH expression. 4-OI protects against lipopolysaccharide-induced lethality in vivo and inhibits cytokine release. These findings show that 4-OI has anti-inflammatory effects by targeting GAPDH to decrease aerobic glycolysis in macrophages.
A type-II superlattice period with a modified InAs to GaSb thickness ratio for midwavelength infrared photodiode performance improvement (2010)

We present a type-II superlattice period with a modified InAs to GaSb thickness ratio for midinfrared detection. In this kind of structure, the large electron-hole wave-function overlap and the low intrinsic carrier concentration lead to a significant signal-to-noise ratio enhancement. For the proof of concept, a sample designed with an InAs to GaSb thickness ratio close to 2 was grown. Comparison with standard design photodiodes shows an improvement of the differential resistance area product by one and a half decade while the quantum efficiency was more than doubled.
A Technique for Adaptive Voice Flow Control in Integrated Packet Networks (1980)

Integrated packet-switched networks have potential for providing improved performance by dynamically sharing transmission bandwidths between various users and user types, but new flow control methods are needed to deal with packetized voice traffic. This paper describes a packet voice flow control concept based on embedded speech coding. Results are presented from a computer simulation study of the technique in the context of a multilink wideband packet speech network. Several control methodologies are described, leading to an end-to end feedback approach that achieves stable operation and efficient utilization of network resources by adaptively matching transmitted voice bit rates to prevailing network conditions. Issues in the design of embedded speech coding algorithms are reviewed and a candidate structure based on channel vocoding principles is presented, along with the subjective results of some preliminary listening tests
Large-scale training to increase speech intelligibility for hearing-impaired listeners in novel noises (2016)

Supervised speech segregation has been recently shown to improve human speech intelligibility in noise, when trained and tested on similar noises. However, a major challenge involves the ability to generalize to entirely novel noises. Such generalization would enable hearing aid and cochlear implant users to improve speech intelligibility in unknown noisy environments. This challenge is addressed in the current study through large-scale training. Specifically, a deep neural network (DNN) was trained on 10 000 noises to estimate the ideal ratio mask, and then employed to separate sentences from completely new noises (cafeteria and babble) at several signal-to-noise ratios (SNRs). Although the DNN was trained at the fixed SNR of - 2 dB, testing using hearing-impaired listeners demonstrated that speech intelligibility increased substantially following speech segregation using the novel noises and unmatched SNR conditions of 0 dB and 5 dB. Sentence intelligibility benefit was also observed for normal-hearing listeners in most noisy conditions. The results indicate that DNN-based supervised speech segregation with large-scale training is a very promising approach for generalization to new acoustic environments.
Chloroquine Treatment Enhances Regulatory T Cells and Reduces the Severity of Experimental Autoimmune Encephalomyelitis (2013)

We show for the first time that CQ treatment promotes the expansion of Treg cells, corroborating previous reports indicating that chloroquine has immunomodulatory properties. Our results also show that CQ treatment suppress the inflammation in the CNS of EAE-inflicted mice, both in prophylactic and therapeutic approaches. We hypothesized that the increased number of regulatory T cells induced by the CQ treatment is involved in the reduction of the clinical signs of EAE.

A new measurement of ionic mobility in insulators by thermally stimulated currents (1982)

Ionic mobilities in insulators have been derived from transit times observed in polarity reversal measurements [1]. In the derivation, the effects of space charge field and diffusion are neglected. However, mobile ions build up space charge fields in the insulators and distort the inner fields. In the strict sense, not only drift of ions, but also diffusion and space charge field should be regarded in order to express behavior of mobile ions.
Bulk trap formation by high temperature annealing of buried thermal oxides [SIMOX] (1995)

The formation of electron and hole traps has been investigated in thermally grown silicon dioxide that was encapsulated by polysilicon and annealed at temperatures ranging from 1100 to 1325/spl deg/C. Three buried oxide thicknesses have been examined: 25, 100 and 400 nm. Using the cryogenic detrapping technique, trapping of holes and electrons in traps up to 2 eV deep (tunneling depth) has been measured. The dependence of trap formation on the oxide thickness and annealing temperature suggest that the oxygen deficiency responsible for trap formation is diffusion limited and the formation rate is consistent with the SiO diffusion data published by Cellers et al. [1989]. In addition to the shallow electron trap at 1 eV, a deeper electron trap at 1.7 eV that remains occupied at room temperature is present during the early stages of oxygen depletion. Once the formation of electron traps has saturated, the deeper trap is not observed. During irradiation, the ratio of the number of electrons captured in traps or recombining with trapped holes to the number escaping the oxide is affected by the oxide thickness. The effect of the oxide thickness on the retention of electrons within the oxide is discussed. TEM micrographs show within the polysilicon during the interface between the polysilicon and oxide, but no effect on charge trapping has been observed.
Cell selection in two-tier femtocell networks using Q-learning algorithm (2014)

Next-generation wireless networks will generate a heterogeneous network with micro base station (MBS) and femtocells where cell selection becomes crucial for balancing the utilization of the whole network. In this paper, we investigate cell selection problem in a two-tier femtocell network that contains a MBS and several femtocells with open/closed access methods and coverage areas. The selection process among groups of users in different service areas is formulated as a dynamic evolutionary game. In order to achieve an equilibrium, we present the Q-learning algorithm that can help distributed individual users adapt the situation and make cell selection decisions independently. With their own knowledge of the past, the users can learn to achieve the equilibrium without a centralized controller to gather other users information. Finally, simulation results present the convergence and effectiveness of the proposed algorithm.
Magneto-optical enhancement by surface plasmon resonance in magnetic “nano-onions” with multicore-shell structures (2005)

Calculations based on the Maxwell–Garnett theory revealed a remarkable enhancement of the magneto-optical effect due to surface plasmon resonance excited in nanometer sized magnetic particles (“nano-onions”) with n-fold core-shell structures consisting of shell(s) and/or a core of noble metals such as Au and Ag. The Kerr effect was found to be greatly enhanced in a composite containing nano-onions of threefold Fe(orCoFe2O4)(core)∕dielectric(shell)∕Ag(shell) structure and also in a composite containing twofold Bi-YIG(core)∕Ag(shell) nano-onions. In the latter case, the Kerr rotation angle as large as 13.5° was obtained with a figure of merit, θKR=62°, (R is the reflectivity) at ℏω=2.6eV, which is much larger than the highest values of θK=19° and θKR=1.1°, reported for PtMnSb.
A low-valent dinuclear ruthenium diazadiene complex catalyzes the oxidation of dihydrogen and reversible hydrogenation of quinones (2018)

The dinuclear ruthenium complex [Ru<sub>2</sub>H(μ-H)(Me<sub>2</sub>dad)(dbcot)<sub>2</sub>] contains a 1,4-dimethyl-diazabuta-1,3-diene (Me<sub>2</sub>dad) as a non-innocent bridging ligand between the metal centers to give a [Ru<sub>2</sub>(Me<sub>2</sub>dad)] core. In addition, each ruthenium is bound to one dibenzo[<i>a</i>,<i>e</i>]cyclooctatetraene (dbcot) ligand. This Ru dimer converts H<sub>2</sub> to protons and electrons. It also catalyzes reversibly under mild conditions the selective hydrogenation of vitamins K<sub>2</sub> and K<sub>3</sub> to their corresponding hydroquinone equivalents without affecting the C[double bond, length as m-dash]C double bonds. Mechanistic studies suggest that the [Ru<sub>2</sub>(Me<sub>2</sub>dad)] moiety, like hydrogenases, reacts with H<sub>2</sub> and releases electrons and protons stepwise.
What you don't know can't help you: pension knowledge and retirement decision making (2005)

This paper provides an answer to an important empirical puzzle in the retirement literature: while most people know little about their own pension plans, retirement behavior is strongly affected by pension incentives. We combine administrative and self-reported pension data to measure the retirement response to actual and perceived financial incentives. While virtually all recent empirical work has relied on administrative- or employer-reported data, we document an important role for self-reported pension data in determining retirement behavior. Well-informed individuals are five times more responsive to pension incentives than the average. In contrast, ill-informed individuals respond to their own misperceptions of the incentives rather than being unresponsive to any measured incentives.
Modeling of an internal combustion engine for control analysis (1988)

Recent activity in nonthermodynamic modeling of automotive internal combustion engines with spark ignition, which are inherently nonlinear, is reviewed. A fundamental nonlinear model of the engine is presented, and a linear control-oriented model is derived from the nonlinear process. Techniques for experimental verification are examined, and a practical linear engine example incorporating multirate sampling is illustrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
