A Wide-Range Highly Power Efficient RF-to-DC Rectifier for RF Energy Harvesting Systems (2018)

In this paper, a wide input range, 4-stage threshold voltage compensated RF-DC power converter is introduced. A novel threshold voltage compensation scheme is proposed that can be applied to a rectifier chain with a relatively low number of stages. This proposed structure is shown to provide a high power conversion efficiency (PCE) over a wide input power range that increases the coverage area of wireless powering. Designed and simulated in IBM 130-nm CMOS technology, the proposed 915-MHz rectifier exhibits a PCE of above 20% over the 20-dB input power range while driving a load resistor. For the same load, utilizing a minimal number of compensated rectifier stages, the proposed circuit exhibits a record maximum PCE of 52% at -10 dBm for single-ended Dickson-based CMOS rectifiers. The proposed circuit demonstrates a -22.3 dBm sensitivity for 1 V output across a 1-MΩ resistive load.
The Correlation Between Tympanic Membrane Temperature and Specific Region of Face Temperature (2017)

Facial temperature measurements using infrared thermography (IRT) will be allowed screening travelers with high fever quickly and safely at airports or national borders if we have the formula for calculating tympanic temperature or reference standard temperature tables. This study was conducted to investigate whether the recommended position in the ISO guidelines for facial themograms measured by IRT best reflects tympanic temperature or whether other specific areas are better represented. Data were collected from NHIS Ilsan Hospital from August 2016 to December 2016. A total of 508 subjects were included in this study. The six regions of interest (ROI) of eye (medial canthus, cornea, sclera between medial canthus and cornea both side) and one ROI of inter-brow of face were defined and measured the temperature and they compared with the eardrum temperature. The results showed that the tympanic membrane temperature and medial canthus were the most similar. And a model to predict tympanic temperature through statistical bias correction can be developed.
Efficacy and safety of brodalumab in patients with generalized pustular psoriasis and psoriatic erythroderma: results from a 52-week, open-label study (2016)

Brodalumab significantly improved the symptoms of patients with GPP and PsE throughout the 52 weeks, and demonstrated favourable safety profiles without any new safety signals. Inhibition of IL-17RA-mediated signalling by brodalumab is expected to be a promising new treatment option for patients with GPP and PsE.
How to use hand-held computers to evaluate wood drying. (1985)

Techniques have been developed to evaluate end generate wood drying curves with hand-held computers (3-5K memory). Predictions of time to dry to a specific moisture content, drying rates, and other characteristics of wood drying curves can be made. The paper describes the development of programs and illustrates their use.
Mesoporous Films and Polymer Brushes Helping Each Other To Modulate Ionic Transport in Nanoconfined Environments. An Interesting Example of Synergism in Functional Hybrid Assemblies (2009)

Rational design of fully synthetic platforms displaying active control over ionic transport in close resemblance to biological systems represents an ongoing challenge in molecular materials science. Here, we demonstrate that the synergism arising from the chemistries involved in mesoporous films and polymer brushes is a key enabler to next-generation "smart" nanofilters capable of mimicking the gating functions of specific biological channels. Hybrid functional assemblies constituted of mesoporous silica films modified with polyzwitterionic brushes are able to discriminate and gate the transport of cations while the passage of anionic species is precluded. The synthetic membranes behave as proton-gated cation-selective platforms mimicking the functioning of acid-sensing ion channels encountered in the neurons of the central nervous system. We believe that this experimental evidence will stimulate further multidisciplinary work across the boundaries of materials chemistry to attain new functional nanostructured interfaces with transport properties so far believed to be exclusive features of biological channels.
Cation-controlled assembly of Na+-linked lacunary α-Keggin tungstosilicates (2005)

Two novel salts of lacunary tungstosilicates with guanidinium and alkali metal cations, (CH6N3)7Na[SiW11O39].(CH3)2CO.8H2O (1) and (CH6N3)K6Na[SiW11O39].11.5H2O (2), have been synthesized and their crystal structures have been determined by synchrotron X-ray diffraction. In both crystals, the Na+ cations link the lacunary Keggin-type tungstosilicate anions into linear structures. The neighboring [SiW11O39]8- anions are related by two-fold screw and translational operations in compounds 1 and 2, respectively. Second harmonic generation was observed for compound 1.
Efficient Acid-Catalyzed Conversion of Phenylglyoxal to Mandelates on Flame-Derived Silica/Alumina (2013)

Amorphous, nonporous silica/alumina (SA) made by flame-spray pyrolysis (FSP) efficiently catalyzes the direct conversion of phenylglyoxal (PG) to alkyl mandelates. The SAs exhibited a turnover frequency more than an order of magnitude higher than dealuminated zeolite Y, which hitherto has been considered as the most active solid acid for this reaction. The free diffusion of PG to surface acid sites and rapid removal of mandelate products are proposed to be at the origin of the superior performance of SAs. The recyclability of the catalyst was tested in five repetitive runs and showed no significant loss of catalyst performance.
Estrogen Effects on Cognitive and Synaptic Health Over the Lifecourse (2015)

Estrogen facilitates higher cognitive functions by exerting effects on brain regions such as the prefrontal cortex and hippocampus. Estrogen induces spinogenesis and synaptogenesis in these two brain regions and also initiates a complex set of signal transduction pathways via estrogen receptors (ERs). Along with the classical genomic effects mediated by activation of ER α and ER β, there are membrane-bound ER α, ER β, and G protein-coupled estrogen receptor 1 (GPER1) that can mediate rapid nongenomic effects. All key ERs present throughout the body are also present in synapses of the hippocampus and prefrontal cortex. This review summarizes estrogen actions in the brain from the standpoint of their effects on synapse structure and function, noting also the synergistic role of progesterone. We first begin with a review of ER subtypes in the brain and how their abundance and distributions are altered with aging and estrogen loss (e.g., ovariectomy or menopause) in the rodent, monkey, and human brain. As there is much evidence that estrogen loss induced by menopause can exacerbate the effects of aging on cognitive functions, we then review the clinical trials of hormone replacement therapies and their effectiveness on cognitive symptoms experienced by women. Finally, we summarize studies carried out in nonhuman primate models of age- and menopause-related cognitive decline that are highly relevant for developing effective interventions for menopausal women. Together, we highlight a new understanding of how estrogen affects higher cognitive functions and synaptic health that go well beyond its effects on reproduction.
Impact of FD-SOI on Deep-Sub-100-nm CMOS LSIs -A View of Memory Designers- (2006)

A planar double-gate FD-SOI is compared with the bulk CMOS in terms of low-voltage operations. It turns out that due to the small VT variation the FD-SOI is suitable for deep-sub-1 V operations with improved voltage margin of RAM cells and sense amplifiers, and reduced speed variations of logic gates
The Cdk-Activating Kinase Cak1p Promotes Meiotic S Phase through Ime2p (2003)

CAK1 encodes an essential protein kinase in Saccharomyces cerevisiae that is required for activation of the Cdc28p Cdk. CAK1 also has several CDC28-independent functions that are unique to meiosis. The earliest of these functions is to induce S phase, which is regulated differently in meiosis than in mitosis. In mitosis, Cdc28p controls its own S-phase-promoting activity by signaling the destruction of its inhibitor, Sic1p. In meiosis, Sic1p destruction is signaled by the meiosis-specific Ime2p protein kinase. Our data show that Cak1p is required to activate Ime2p through a mechanism that requires threonine 242 and tyrosine 244 in Ime2p's activation loop. This activation promotes autophosphorylation and accumulation of multiply phosphorylated forms of Ime2p during meiotic development. Consistent with Cak1p's role in activating Ime2p, cells lacking Cak1p are deficient in degrading Sic1p. Deletion of SIC1 or overexpression of IME2 can partially suppress the S-phase defect in cak1 mutant cells, suggesting that Ime2p is a key target of Cak1p regulation. These data show that Cak1p is required for the destruction of Sic1p in meiosis, as in mitosis, but in meiosis, it functions through a sporulation-specific kinase.

Solubility: very soluble in most organic solvents including hydrocarbons. Form Supplied in: green solid; available from Aldrich Chemical Co. The linear alkylbenzene side chains consist of a mixture of 1% C10, 40% C11, 28% C12 and 31% C13. Preparative Methods: from dirhodium tetraacetate by ligand exchange with N-[1-(dodecylphenyl)sulfonyl]-(2S)-prolinate.2 Purification: further purification is generally not necessary. May be dried by heating under vacuum at 100 °C. May be purified by column chromatography on silica with ether/petroleum ether as solvent. If contaminated with the free ligand, can be purified by dissolving in diethyl ether and extracting the organic layer with aqueous sodium bicarbonate, followed by drying the organic layer over MgSO4, then filtering and evaporation of the solvent. Handling, Storage, and Precautions: the catalyst is moisture, air, and thermally stable. It may be stored at room temperature for extended periods of time without any apparent decomposition. The toxicity of the title reagent, Rh2(S-DOSP)4, is unknown. Strong nucleophiles such as nitriles, phosphines, amines, pyridines, and sulfides will tend to coordinate to the axial site of the catalyst. This may cause partial poisoning of the catalyst or catalyst decomposition, depending on the coordinating ligand. Reactions carried out under non-anhydrous conditions tend to result in lower enantioselectivity.3
La méthode pgd appliquée à l'équation de la chaleur non-linéaire : vers une formulation performante (2013)

La méthode PGD permet de calculer la solution d'une EDP directement sous forme séparée. Cet algorithme est efficace quand il n'est pas nécessaire de reconstruire le champ recherché au cours des itérations. Généralement les termes non-linéaires conduisent à cette reconstruction. Nous analysons plusieurs approches permettant de limiter, voire de supprimer ces reconstructions. Les résultats obtenus sont illustrés sur l'équation de la chaleur avec une conduction non linéaire.
Semi‐automated quantification of geographic atrophy with blue‐light autofluorescence and spectral‐domain optical coherence tomography: a comparison between the region finder and the advanced retinal pigment epithelium tool in the clinical setting (2019)

Semi-automated analysis of geographic atrophy with RF and ARPET is equally reliable and reproducible in clinical settings, despite both algorithms require frequent adjustment by users. The ARPET restricts size measurements to the central 5 mm, which limits its ability to fully track GA progression. Results of both tools are not interchangeable as measurements with ARPET result in larger lesion sizes.
Ultrafast Transparent Ceramic Scintillators Using the Yb$^{3+}$ Charge Transfer Luminescence in RE$_{2}$O$_{3}$ Host (2011)

We report a new discovery of Yb3+-doped ultrafast scintillators based on the Yb3+ charge transfer luminescence. Transparent ceramic Yb3+-doped Y2O3, Sc2O3, Lu2O3 and Yb2O3 were prepared by sintering. When irradiated by gamma and X-rays, they showed a well detectable photoabsorption peak in the pulse height spectra and ultrafast scintillation decay dominated by the decay time of about 1 ns. For the first time, the Yb3+-doped oxide materials show detectable scintillation in the pulse height measurement at room temperature with ultafast scintillation decay.
Engineering and application of synthetic nar promoter for fine-tuning the expression of metabolic pathway genes in Escherichia coli (2018)

The synthetic <i>nar</i> promoters, which were engineered to have strong, intermediate, and weak intensities, were successfully applied to metabolic engineering of d-lactate and 2,3-BDO pathways in <i>E. coli</i>. By controlling expression levels of d-lactate and 2,3-BDO pathway enzymes using the synthetic <i>nar</i> promoters, the production of d-lactate and 2,3-BDO was increased over that using the wild-type promoter by 34 and 72%, respectively. Thus, this synthetic promoter module system will support the improved production of biochemicals and biofuels through fine-tuning of gene expression levels.
Selective membranes for the construction and optimization of an amperometric oxalate enzyme electrode (1994)

Oxalate oxidase has been immobilized within a membrane laminate. Integration of the laminate within an amperometric electrode afforded a sensor for determining oxalate via electrochemical oxidation of H2O2 and subsequent current generation. A study of novel poly(vinyl chloride) (PVC) and cellulose acetate (CA) membranes with various outer/inner membrane configurations made it possible to eliminate direct electrochemical interference from species present in urine, typically ascorbate (60-500 mumol l-1), homovanillic acid (40-60 mumol l-1) and oxalate itself (50-500 mumol l-1). Of the membranes studied, only CA and plasticized PVC were found to screen out the direct oxalate electrochemical signal effectively. Cellulose acetate exhibited the best selectivity ratio for H2O2 over urine interference. An outer 0.05 micron pore radius polycarbonate membrane imparted sensor linearity in the narrow range 2-200 mumol l-1 oxalate, which fell below the normal range of oxalate in urine. The application of unplasticized PVC as an outer membrane allowed the sensor to exhibit linear characteristics which extended beyond the clinically relevant range (> 700 mumol l-1). The Michaelis-Menten constant of the immobilized enzyme was measured and found to be 10(-3) mol l-1.
Improved two-party and multi-party purification protocols (2002)

We present an improved protocol for entanglement purification of bipartite mixed states using several states at a time rather than two at a time as in the traditional recurrence method. We also present a generalization of the hashing method to n-partite cat states, which achieves a finite yield of pure cat states for any desired fidelity. Our results are compared to previous protocols.
Scattering Matrix Parameters of a Step Discontinuity in a Coplanar Waveguide (2005)

The dominant and higher order modes for a closed coplanar wave guide (CPW) in the even and odd-mode excitation are accurately described from a thorough spectral-domain approach. Scattering parameters of the dominant mode in the Ka-band for a step in width CPW discontinuity are presented for both even and odd-mode. Equivalent circuit parameters for the discontinuity valid for the whole Ka-band are also given.
Optimization of plunger pump suction manifold parameters (2022)

Hydraulic fracturing plays an important role in increasing oil and gas reserves. In hydraulic fracturing, fluid is injected until the fluid pressure overcomes the stresses inherent in the rock or exceeds the forces holding the rock together. The fracturing fluid is a cohesive-dispersed system characterized by a continuous spatial structure. It is assumed that the configuration of the suction manifold, velocity and pressure pulsations lead to changes in the volumetric characteristics of the system phases at the pump outlet. The purpose of the study, is to analyze the movement of liquid with proppant through three suction manifolds of different design, to identify the design with the lowest volume of proppant sedimentation. The paper considers three design variants of suction manifold of high-pressure plunger pump. The hydrodynamic analysis of fluid motion with proppant has been carried out, data on distribution of velocities, pressures and proppant concentration in the manifold have been obtained. A series of numerical experiments carried out for different designs of three-plunger pump suction lines confirms the hypothesis about influence of manifold design, velocity and pressure pulsation on change of volume characteristics of system phases.
Field mapping with the magnetic resonance force microscope (1999)

We have developed magnetic resonance force microscopy for quantitative measurements of magnetic fields. A microscopic particle attached near the end of a microcantilever serves as the field sensing probe. We have demonstrated two-dimensional field mapping with a lateral resolution of 3.2 μm and a field resolution of 0.19 mT (1.9 G). The instrument holds considerable promise for field mapping with spatial resolution better than 0.1 μm at room temperature. Applications include field mapping of magnetic recording heads.
The development of ceramic injection molding. (1987)

The method of forming thin ZrO2 bodies by Injection molding process using acrylic binder was studied. Concerning reological characteristics and properties of thermal decomposition, acrylic binder was compared with the more generally used wax binder. The flowing characteristics of the mixture of acrylic binder indicated high viscosity and gradual change in relation between temperature and viscosity. The compacts using acrylic binder had high flexural strength compared with those using wax binder. As a result, it was observed that ZrO2 mixed with acrylic binder filled the mold without defects. A mechanism for removing acrylic binder from compact which is different from that of wax binder was found. This mechanism made it possible to remove, without defects, acrylic binder, and to control the quantity of gas which decomposes the binder in the inner part of compact. Mixture with 45vol% acrylic binder was the best composition for injection moldability and removing binder. Sintered ZrO2 compact was densified by HIP (Hot Isostatic Pressing), and its mechanical properties were equal to those of the conventional process.
The product of the geneGEF1ofSaccharomyces cerevisiaetransports Clâacross the plasma membrane (2007)

Expression of GEF1 in Xenopus laevis oocytes and HEK-293 cells gave rise to a Cl- channel that remained permanently open and was blocked by nitro-2-(3-phenyl-propylamino) benzoic acid and niflumic acid. NPPB induced petite-like colonies, resembling the GEF1 knock-out. The fluorescent halide indicator SPQ was quenched in a wild-type strain, in contrast to both a GEF1 knock-out strain and yeast grown in the presence of NPPB. Immunogold and electron microscopy located Gef1p in the plasma membrane, vacuole, endoplasmic reticulum and Golgi apparatus. Eleven substitutions in five residues forming the ion channel of GEF1 were introduced; some of them (S186A, I188N, Y459D, Y459F, Y459V, I467A, I467N and F468N) did not rescue the pet phenotype, whereas F468A, A558F and A558Y formed normal colonies. All the pet mutants showed reduced O2 consumption, small mitochondria and mostly disrupted organelles. Finally, electron microscopy revealed that the plasma membrane of the mutants develop multiple foldings and highly ordered cylindrical protein-membrane complexes. All the experiments above suggest that Gef1p transports Cl- through the plasma membrane and reveal the importance of critical amino acids for the proper function of the protein as suggested by structural models. However, the mechanism of activation of the channel has yet to be defined.
High Coulombic Efficiency Na–O2 Batteries Enabled by a Bilayer Ionogel/Ionic Liquid (2019)

Sodium-oxygen (Na-O<sub>2</sub>) cells are a promising high energy density storage technology with a theoretical specific energy of 1605 Wh kg<sup>-1</sup>. However, this technology faces certain challenges in order to achieve both a high practical energy density as well as long-term cycling capability. In this Letter, a superior Coulombic cyclic efficiency, close to 100%, has been demonstrated by the use of a bilayer electrolyte composed of an ionogel and an ionic liquid electrolyte, reported herein for the first time. The presence of the ionogel plays a major role in the prevention of side reactions originating at the anode, providing a promising route to extend cell cycling, whereas the ionic liquid is essential to support high reaction rates at the cathode.
New food antioxidant additive based on hydrolysis products of lactose (2003)

The hydrolysis products of lactose, D-glucose and D-galactose, were oxidized in two consecutive steps using appropriate bimetallic catalysts (Bi–Pd, Bi–Pt on charcoal) to the corresponding 2-ketoaldonic acids. The latter were further processed to provide two stereoisomers of L-ascorbic acid (vitamin C), D-ascorbic acid (D-lyxoascorbic acid) and erythorbic acid (D-araboascorbic acid). The antioxidant activity of these two isomers as well as that of the equimolar mixture thereof was evaluated by measuring their reducing activity against DPPH (2,2-diphenyl-1-picrylhydrazyl) and their scavenging activity of O2− species in the presence of NBT (Nitro Blue Tetrazolium). The compounds and their equimolar mixture were found to exhibit the same antioxidant activity as L-ascorbic acid suggesting that they may be used as cheap alternatives to L-ascorbic acid as food antioxidant additives when the vitamin C activity is not required.
