Oat Phytochrome 1s Biologically Active in Transgenic Tomatoes (2013)

To determine the functional homology between phytochromes from evolutionarily divergent species, we used the cauliflower mosaic virus 35s promoter to express a monocot (oat) phytochrome cDNA in a dicot plant (tomato). lmmunoblot analysis shows that more than 50 % of the transgenic tomato plants synthesize the full-length oat phytochrome polypeptide. Moreover, leaves of light-grown transgenic plants contain appreciably less oat phytochrome than leaves from dark-adapted plants, and etiolated R I transgenic seedlings have higher levels of spectrally active phytochrome than wild-type tomato seedlings in direct proportion to the leve1 of immunochemically detectable oat polypeptide present. These data suggest that the heterologous oat polypeptide carries a functional chromophore, allowing reversible photoconversion between the two forms of the molecule, and that the far-red absorbing form (Pfr) is recognized and selectively degraded by the Pfr-specific degradative machinery in the dicot cell. The overexpression of oat phytochrome has pleiotropic, phenotypic consequences at all major phases of the life cycle. Adult transgenic tomato plants expressing high levels of the oat protein tend to be dwarfed, with dark green foliage and fruits. R1 transgenic seedlings have short hypocotyls with elevated anthocyanin contents. We conclude that a monocot phytochrome can be synthesized and correctly processed to a biologically active form in a dicot cell, and that the transduction pathway components that interact with the photoreceptor are evolutionarily conserved.
A dq-Domain Impedance Measurement Methodology for Three-Phase Converters in Distributed Energy Systems (2018)

A distributed energy system (DES) using controlled power electronics converters delivers power to loads, via conventional, as well as a number of renewable, energy sources. However, stability concerns retard the integration of power electronics converters into an existing DES. Therefore, due to the high penetration of power converters, the overall network analysis of DES is becoming increasingly difficult. Impedance-based DES modeling emerged as an effective technique as it reduces the system into source and load subsystems and offers easier analysis of the dynamic interactions between them. These models can be obtained using either analytical calculations, simulations, or experimental measurements. In this work, firstly, a line-to-line current injection technique is used for the measurement of alternating current (AC) impedances. Since it requires repeated injections, a d q -domain impedance measurement methodology based upon a set of independent perturbations and measurements is proposed. The perturbation is injected via a sweep signal which is preprocessed by the digital signal processor (DSP) prior to injection. The d q reference frame is synchronized with the three-phase AC system using a low-bandwidth phase-locked loop (PLL). The close matching of impedance parameters measured in simulation using the proposed approach with those obtained using analytical expressions and the line-to-line current injection technique verifies the effectiveness of the approach. Furthermore, the method was also implemented experimentally, and the close matching of the results with the analytical and simulation results validates the overall modeling and measurement procedure.
Recurrent epithelial ovarian cancer: pharmacotherapy and novel therapeutics (2007)

Epithelial ovarian cancer will strike between 1 - 2% of women in developed countries and, unfortunately, it largely remains a lethal disease due to late-stage at diagnosis and the eventual development of chemotherapy resistance. Ovarian cancer is initially treated with surgical resection and chemotherapy (primarily platinum/taxane combinations) and remission can be attained for the majority of patients. Despite this, most women will recur and require multiple further therapies. The purpose of this paper is to review the existing treatment options, including surgery, traditional chemotherapy as well as upcoming novel and targeted therapies that may one day improve outcomes in this disease.
Recursive eigendecomposition via autoregressive analysis and ago-antagonistic regularization (2002)

A new recursive eigendecomposition algorithm of complex Hermitian Toeplitz matrices is studied. Based on Trench's inversion of Toeplitz matrices from their autoregressive analysis, we have developed a fast recursive iterative algorithm that takes into account the rank-one modification of successive order Toeplitz matrices. To speed up the computational time and to increase numerical stability of ill-conditioned eigendecomposition in case of very short data records analysis, we have extended this method by introducing an ago-antagonistic regularized reflection coefficient via Levinson equation. We provide a geometrical interpretation of this new recursive eigendecomposition.
Manipulation of Individual Carbon Nanotubes by Reconstructing the Intracellular Transport of a Living Cell (2009)

We used kinesin motor protein and its microtubule track to transport multi-walled carbon nanotubes (MWNTs) on engineered surfaces. Using a flow chamber, surface-adsorbed kinesins are shown to transport red-labeled microtubules loaded with green cargos of MWNTs. Our results establish a platform for assembling individually addressable MWNT nanostructures using microtubule templates.
Zinc oxide/<i>n</i>-Si junction solar cells produced by spray-pyrolysis method (1995)

Zinc oxide (ZnO)/n-Si junction solar cells were fabricated by a spray-pyrolysis method and high short-circuit photocurrent densities and relatively high photovoltages were obtained by adjusting the conditions of the deposition and the post-deposition heat treatment. Consequently, relatively high conversion efficiencies ranging between 6.9% and 8.5% were obtained. The efficiency of the solar cells with ZnO/n-Si structure decreases slowly with time when they are kept in air in the dark because of the increase in the thickness of the silicon oxide layer between Si and the ZnO film. This degradation can be avoided by forming an indium-tin-oxide (ITO) overlayer on the ZnO film, indicating that the silicon oxide layer grows through the reaction of Si with oxygen diffusing from the atmosphere, not with ZnO. The efficiency of the ZnO/n-Si junction solar cells decreases rapidly with the illumination time. Capacitance-voltage measurements show that this degradation is caused by a decrease in the work function of the ZnO film. The decrease in the work function is caused by desorption of O−2 from the grain boundaries of the ZnO films. When incident light contains no ultraviolet (UV) component, this degradation does not occur, indicating that the desorption is caused by the acceptance of holes generated by UV light.
A 1.1 nW Energy-Harvesting System with 544 pW Quiescent Power for Next-Generation Implants (2014)

This paper presents a nW power management unit (PMU) for an autonomous wireless sensor that sustains itself by harvesting energy from the endocochlear potential (EP), the 70-100 mV electrochemical bio-potential inside the mammalian ear. Due to the anatomical constraints inside the inner ear, the total extractable power from the EP is limited to 1.1-6.25 nW. A nW boost converter is used to increase the input voltage (30-55 mV) to a higher voltage (0.8 to 1.1 V) usable by CMOS circuits in the sensor. A pW Charge Pump circuit is used to minimize the leakage in the boost converter. Further, ultra-low-power control circuits consisting of digital implementations of input impedance adjustment circuits and Zero Current Switching circuits along with Timer and Reference circuits keep the quiescent power of the PMU down to 544 pW. The designed boost converter achieves a peak power conversion efficiency of 56%. The PMU can sustain itself and a duty-cyled ultra-low power load while extracting power from the EP of a live guinea pig. The PMU circuits have been implemented on a 0.18µm CMOS process.
Polariton chemistry: controlling molecular dynamics with optical cavities (2018)

Molecular polaritons are the optical excitations which emerge when molecular transitions interact strongly with confined electromagnetic fields. Increasing interest in the hybrid molecular-photonic materials that host these excitations stems from recent observations of their novel and tunable chemistry. Some of the remarkable functionalities exhibited by polaritons include the ability to induce long-range excitation energy transfer, enhance charge conductivity, and inhibit or accelerate chemical reactions. In this review, we explain the effective theories of molecular polaritons which form a basis for the interpretation and guidance of experiments at the strong coupling limit. The theoretical discussion is illustrated with the analysis of innovative applications of strongly coupled molecular-photonic systems to chemical phenomena of fundamental importance to future technologies.
Three Degradation Parameters Estimation of a LIB Module Using Single Indicator for In-situ Charge–Discharge Energy Prediction (2018)

The co-operation of distributed batteries in the smart grid or virtual power plant is called `battery aggregation'. Especially the lithium-ion battery (LIB) is the strong candidate of the aggregated battery. The degradation of the lithium-ion battery causes the increase of charge-discharge energy (CDE) loss and the decrease of economic gain. We studied the charge-discharge energy estimation method for the economic operation of battery aggregation using lithium-ion batteries. The charge-discharge energy of lithium-ion battery is determined by full-charge capacity (FCC), open-circuit voltage (OCV), and internal impedance. We found out the single indicator that can estimate above-mentioned three parameters. In this paper, we discuss about the results of CDE estimation using this single indicator.
Context awareness in mobile computing: A review (2013)

Context awareness is increasingly gaining applicability in interactive ubiquitous mobile computing systems. In order to apply this concept in design of applications for dynamic environments, it is necessary to understand what constitutes context awareness, the classification of context and context-aware development frameworks. The concept of context awareness is discussed, various approaches to context awareness are reviewed, and important aspects of context-aware mobile computing are analysed. Recommendations for better understanding of context awareness and design principles for development of context-aware applications are provided.
Cerebellar cortex lesions disrupt learning-dependent timing of conditioned eyelid responses (1993)

Among the many issues surrounding the involvement of the cerebellum in motor learning, the relative roles of the cerebellar cortex and cerebellar nuclei in Pavlovian conditioning have been particularly difficult to assess. While previous studies have investigated the effects of cerebellar cortex lesions on the acquisition and retention of conditioned movements, we have examined the effects of these lesions on the timing of Pavlovian eyelid responses. The rationale for this approach arises from previous studies indicating that this timing is a component of Pavlovian eyelid responses that is learned and that involves temporal discrimination. To permit within-animal comparisons, rabbits were trained to produce differently timed responses to high- and low-frequency auditory conditioned stimuli (CSs). Before the lesion the conditioned responses to both CSs were appropriately timed--each peaked near the time at which the unconditioned stimulus was presented for that CS. However, after the lesion both CSs could elicit similarly timed conditioned responses that peaked inappropriately at very short latencies. The changes in responses timing were sensitive to the size of the lesion, particularly its rostral-caudal extent. Similar results were obtained in animals trained with one CS, indicating that the disruption of response timing is not related to impaired auditory discrimination. Because response timing is learned and therefore requires synaptic plasticity, these data suggest that there are at least two sites of plasticity involved in the motor expression of Pavlovian eyelid responses. Plasticity at one site is necessary for the learned timing of conditioned responses, while plasticity at another site is revealed by the inappropriately timed responses observed following removal of the cerebellar cortex. This lesion-induced dissociation of the expression of motor responses and their learned timing supports a synthesis of competing views by suggesting that motor learning involves both the cerebellar cortex and cerebellar nuclei. We hypothesize that motor learning involves a decrease in strength of the granule cell-Purkinje cell synapses (e.g., Ito and Kano, 1982) in the cerebellar cortex and an increase in strength of the mossy fiber-cerebellar nuclei synapses (e.g., Racine et al., 1986). Finally, these data suggest that the cerebellar cortex may mediate the temporal discriminations that are necessary for the learned timing of conditioned responses.
Excimer laser direct etching of GaAs (1988)

The direct etching of GaAs substrates by excimer laser light has been studied at wavelengths of 193 nm (ArF). 248 nm (KrF) and 351 nm (XeF). For absorbed laser fluences greater than the direct etching fluence thresholds of 23 mJ cm-2 for ArF, 33 mJ cm-2 for KrF and 80 mJ cm-2 for XeF, the authors observe direct etching in air to depths of order one nanometre per pulse. For low-fluence exposures in either vacuum (10-2 Torr) or N2 (1 atm) environments the etch depth per pulse is less than a quarter of that observed when exposure takes place in air. For higher fluence exposures ( approximately 250 mJ cm-2) the etched regions show signs of melting. Using a line-narrowed KrF excimer laser and holographic interference techniques gratings of period 1.5 mu m were directly etched in GaAs substrates.
Host–guest chemistry at interface for photoswitchable bioelectrocatalysis (2011)

Photoswitchable bioelectrocatalysis of glucose with glucose oxidase in an "On-Off" state is fabricated from host-guest chemistry at an interface by using the photocontrolled reversible immobilization and detachment of ferrocene-labeled redox-polymer as mediator.
Blocking the Receptor for IL-10 Improves Antimycobacterial Chemotherapy and Vaccination (2001)

Novel approaches are required for the prevention and therapy of mycobacterial infections since the only vaccine in use, bacillus Calmette-Guérin, is poorly effective and chemotherapy is long and often ineffective in sterilizing the infection. We used a mouse model of Mycobacterium avium infection to address the usefulness of a mAb able to block IL-10R both in treatment of primary infections and in conventional multidrug therapy and subunit vaccination. Treatment of infected mice with this mAb during the entire period of experimental infection had little impact on the course of M. avium infection, with a slight improvement in the resistance of infected mice observed in the liver and spleen at day 30 of infection, which was associated with increased macrophage activation and priming of CD4(+) T cells for IFN-gamma production. Administration of this mAb later in infection had no effect on its course, but improved the effectiveness of chemotherapy when the latter was started in a chronic phase of infection. Also, the anti-IL-10R mAb acted as an adjuvant in the induction of protective immunity upon vaccination with a mycobacterial subunit preparation.

Real-time Visual Tracker by Stream Processing (2008)

In this work, we implement a real-time visual tracker that targets the position and 3D pose of objects in video sequences, specifically faces. The use of stream processors for the computations and efficient Sparse-Template-based particle filtering allows us to achieve real-time processing even when tracking multiple objects simultaneously in high-resolution video frames. Stream processing is a relatively new computing paradigm that permits the expression and execution of data-parallel algorithms with great efficiency and minimum effort. Using a GPU (graphics processing unit, a consumer-grade stream processor) and the NVIDIA CUDA™ technology, we can achieve performance improvements as large as ten times compared to a similar CPU-only tracker. At the same time, the Stream processing approach opens the door to other computing devices, like the Cell/BE™ or other multicore CPUs.
Organic Sucker Control: Screening Different Active Ingredients for Commercial Application (2020)

Organically derived fatty alcohol is useful for the control of tobacco axillary buds (suckers) and is greatly needed by commercial organic tobacco farmers. Recently, its approval by the U.S. Department of Agriculture (USDA)-National Organic Program has been scrutinized. The objective of this research was to evaluate the suggested alternatives: pelargonic acid, vegetable oil, canola oil, and peppermint + spearmint oil using two different application methods, a standard 3-nozzle boom or a dropline. Chemical injury was not observed within any treatment except for those containing pelargonic acid. Injury was greatest when applied with the 3-nozzle boom and was reduced by nearly 50% with the dropline; however, injury after the dropline application was 2.5 to 7 times greater than any other treatment. Despite significant injury, sucker control was acceptable with pelargonic acid (≈90%) and was similar to that resulting from fatty alcohol (99–100%). Sucker control was <40% among all other treatments, with peppermint + spearmint oil providing better efficacy than canola (10 to 15%) or vegetable oil (−1 to −10%). Cured leaf yield, quality, and value were likewise greatest in fatty alcohol treatments because of maximized sucker control and minimized chemical injury. Producers are encouraged to utilize fatty alcohol until the alternative products can be reformulated and re-evaluated.

It is well established that having an imaginary friend is beneficial to a child. Are we making the most of this useful phenomenon?
Density, Surface Tension, and Kinematic Viscosity of Hydrofluoroethers HFE-7000, HFE-7100, HFE-7200, HFE-7300, and HFE-7500 (2015)

The liquid density, liquid kinematic viscosity, and surface tension of the segregated hydrofluoroethers (HFEs) HFE-7000 (1,1,1,2,2,3,3-heptafluoro-3-methoxy-propane), HFE-7100 (mixture of the isomers 1,1,1,2,2,3,3,4,4-nonafluoro-4-methoxy-butane and 1,1,1,2,3,3-hexafluoro-3-methoxy-2-(trifluoromethyl)propane), HFE-7200 (mixture of the isomers 1-ethoxy-1,1,2,2,3,3,4,4,4-nonafluorobutane and 1-ethoxy-1,1,2,3,3,3-hexafluoro-2-(trifluoromethyl)propane), HFE-7300 (1,1,1,2,2,3,4,5,5,5-decafluoro-3-methoxy-4-(trifluoromethyl)pentane), and HFE-7500 (3-ethoxy-1,1,1,2,3,4,4,5,5,6,6,6-dodecafluoro-2-(trifluoromethyl)hexane) were studied in dependence on temperature under saturation conditions. A vibrating-tube densimeter was used for the measurement of the saturated-liquid density at temperatures from (273.15 to 363.15) K with a relative expanded uncertainty (k = 2) of 0.02 %. The kinematic viscosity of the liquid phase and surface tension were obtained on the basis of surface light scattering (SLS) measurements for temperatures between (273.15 and 373.15) K with estimated relative expanded uncertainties (k = 2) of (2 and 1.5) %. The measured data could be correlated within their expanded uncertainties (k = 2) by interpolating expressions. Effects of the molecular structures of the studied HFEs on the thermophysical data are discussed. In particular for viscosity and surface tension, comparison with literature data is restricted by their scarce availability.
LAPACK's user's guide (1992)

None of these theories is entirely correct or close enough to the truth. However, most of them contain many correct elements (CE). Finding these CE is possible by analysis of these theories. Once the CE are found, they can be merged by synthesis in a better new theory. An analysis of some of the theories of aging followed by synthesis is attempted.
Gö 6983: A Fast Acting Protein Kinase C Inhibitor that Attenuates Myocardial Ischemia/Reperfusion Injury (2006)

Reperfusion injury is characterized by a decrease in endothelial release of nitric oxide within 5 min after reperfusion, increased leukocyte-endothelium interaction, and transmigration of leukocytes into the myocardium, producing cardiac contractile dysfunction. Gö 6983 is a fast acting, lipid soluble, broad spectrum protein kinase C inhibitor. When administered at the beginning of reperfusion, it can restore cardiac function within 5 min and attenuate the deleterious effects associated with acute ischemia/reperfusion. Gö 6983 may offer greater cardioprotection than other broad-spectrum PKC inhibitors in postischemic reperfusion injury because it inhibits PKC(zeta) as well as four other isoforms. The cardioprotection is associated with decreased leukocyte superoxide release and increased endothelial derived nitric oxide from vascular tissue. In vitro studies of human tissue showed that Gö 6983 significantly inhibited antigen-induced superoxide release from leukocytes of patients previously sensitized to tree pollen. In human vascular tissue, Gö 6983 inhibited intracellular Ca(2+) accumulation, suggesting a mechanism for its vasodilator properties. These studies suggest that Gö 6983 would be an effective compound to use in a clinical ischemia/reperfusion setting of organ transplantation and/or cerebral ischemia where inhibiting superoxide release and vasoconstriction in postischemic tissues would allow for better restoration of organ function during reperfusion. However, given the broad-spectrum action of Gö 6983, careful titration of the dose regimen would be recommended to ensure a successful outcome in the setting of organ transplantation and/or cerebral ischemia.
Quantitative targeted absolute proteomics of rat blood–cerebrospinal fluid barrier transporters: comparison with a human specimen (2015)

The purpose of this study was to determine absolute protein expression levels of transporters in rat choroid plexus, that is, the blood-cerebrospinal fluid barrier, and to compare them with the levels in the human choroid plexus. Plasma membrane fractions were prepared from pooled, freshly isolated choroid plexuses of 30 male Wistar rats and from frozen choroid plexus of one male human donor. Protein expression levels of 54 rat and 121 human molecules were measured, using a quantitative targeted absolute proteomics technique. In rat, oatp1a5 showed the most abundant protein expression (30.3 fmol/μg protein), and its expression level was 3.1-, 4.5-, 5.5-, 8.4-, 9.0-, 9.9-, 22-, 91-, and 95-fold greater than those of glut1, oatp1c1, mrp1, mct1, oat3, pept2, mrp4, bcrp, and mdr1a, respectively. OATP1A2 (a possible homolog of rat oatp1a5), OATP1C1 and PEPT2 were not detected in human choroid plexus. MRP1, OAT3, and MRP4 showed 4.0-, 1.8-, and 1.7-fold smaller expression levels in human than rat, respectively. MATE1 was detected in human, but not rat, and its expression level (8.61 fmol/μg protein) was the highest among the xenobiotic transporters examined in human choroid plexus. These findings should be useful for understanding rat blood-cerebrospinal fluid barrier function and its differences from that in human. This is the first study clarifying the absolute protein expression levels of many transporters in the plasma membrane fractions of rat and human choroid plexuses, that is, blood cerebrospinal fluid barrier, by means of quantitative targeted absolute proteomics (QTAP) technique. This study also identified the protein expressions of some transporters including MATE1 and ABCA8 in the choroid plexus for the first time.
