A simple setup to simultaneously measure the resonant frequency and the absolute dissipation factor of a quartz crystal microbalance (1996)

An experimental setup is described that can simultaneously measure the absolute dissipation factor and the resonant frequency of a short-circuited quartz crystal microbalance. The crystal is driven at approximately its resonant frequency by a signal generator which is intermittently disconnected by a relay, causing the crystal oscillation amplitude to decay exponentially. The decay is measured using a ferrite toroid transformer. One of the crystal leads is fed through the center of the ferrite toroid and thereby acts as the primary winding of the transformer. The secondary winding of the transformer is connected to a digitizing oscilloscope which records the decay of the crystal oscillation. From the recorded decay curve, the absolute dissipation factor (calculated from the decay time constant) and the series resonant frequency of the freely oscillating crystal are obtained. Alternatively, the dissipation factor and resonant frequency can be measured for the crystal oscillating under open-circuit conditions, i.e., in the parallel mode. The measurements are automated.

Large displacement low voltage multistable micro actuator (2008)

This paper presents the modeling, design, fabrication and characterization of electrostatic large displacement multistable micro actuators. The device incorporates multiple serially connected bistable elements realized as shallow curved beams of slightly varying length. Loaded by an increasing force provided by an electrostatic comb drive transducer, the device undergoes a sequence of snap- through events and exhibits multiple stable equilibrium configurations at the same voltage. A reduced order (RO) model built using the Rayleigh-Ritz procedure as well as a nonlinear finite element (FE) analysis were used in order to predict the actuator behavior and evaluate design parameters. Devices of four different configurations were fabricated by a deep reactive ion etching (DRIE) based process using silicon on insulator (SOI) wafers. Experimental results demonstrate that the multistable devices exhibit stable displacement of 90mum while four snap-through and snap-back events take place during loading and unloading respectively. Experimental results are found to be in good agreement with the theoretical predictions.
High-energy high-average-power femtosecond fiber system using a QPM-grating pulse compressor (1998)

Summary form only given. We demonstrate a simple and compact chirped pulse amplification (CPA) circuit for boosting both the accessible powers and energies from a femtosecond fiber amplifier. The system is based on a novel pulse compressor, chirped period quasi-phase-matched (QPM) grating, implemented in electric-field poled lithium niobate. A QPM grating compressor is unique in that it combines second-harmonic generation (SHG) and pulse compression in one crystal.
Sex-Related Differences in Relations of Uric Acid to Left Ventricular Hypertrophy and Remodeling in Japanese Hypertensive Patients (2005)

Both hyperuricemia and echocardiographically determined left ventricular (LV) mass have a well-determined association with cardiovascular morbidity and mortality. However, whether or not there is a sex difference in the association of serum uric acid level with LV mass has never been systematically explored. We examined the sex-specific relation of serum uric acid level and echocardiographic indexes of LV structure in never-treated patients with essential hypertension. We enrolled 160 never-treated hypertensive patients (89 men and 71 women) to assess the possible relationship between LV mass and serum uric acid levels. LV measurements were performed according to the recommendations of the American Society of Echocardiography and the Penn Convention. LV mass was indexed by height, body surface area and height raised to the 2.7th power. A positive significant correlation between LV geometry (LV mass, indexed LV mass and relative wall thickness) and serum uric acid level was found in male hypertensive patients but not in female hypertensive patients. Independent determinants of serum uric acid levels in male hypertensive patients were LV mass and serum creatinine levels. In addition, male hypertensive patients with concentric hypertrophy showed the highest serum uric acid levels. In comparison, independent determinants of serum uric acid levels in female hypertensive patients were age and serum creatinine levels. In conclusion, these findings indicate a sex difference in the association of uric acid with LV geometry in Japanese hypertensive patients. In addition, the finding that the highest levels of serum uric acid were observed in our male hypertensive patients with concentric hypertrophy confirmed the previous reports that these patients have the highest risk for cardiovascular morbidity and mortality.
The manufacturing of Si base thin film solar cell modules (2011)

Si based thin film solar cell will be next generation of solar cell products. In order to fabricate high efficiency Si base thin film solar cell, High density (HD) and very high frequency (VHF)-PECVD technologies have been developed for high quality, large scaling ue-Si, μc-SiGe, and μc-SiC film deposition. The high-density and very high frequency plasma technique offers the significant advantages of high plasma density, low plasma potential, and independent control of ion flux and ion bombardment energy which are critical for controlling the bulk and interfacial characteristics of the deposited films. In comparison to other CVD processes, the HD and VHF-PECVD technique offers potential advantages of the deposition of higher growth rates, higher quality films at lower processing temperatures, void free gap filling of high aspect ratio features, self-planarization, lower impurity levels and large scaling capability. The experimental results show typical deposition rate of the μ-Si thin films by HD-PECVD was greater than 10 A/s, the typical microcrystalline volume fraction and the average crystallite size corresponding to 〈111〉 orientation were 75% and 160 Å, respectively. Amorphous SiGe and SiC films have been achieved, μc-SiGe, μc-SiC films are under processing. The stabilized efficiency of tandem junction solar cells with a-Si/μc-Si films can reach 12%.
3 alpha-hydroxysteroid dehydrogenase inhibitory activity of some N(3)-(1-R-4-carboxypyrazol-5-yl)-1,2,3-benzotriazin-4(3H)-one and quinazolin-4(3H)-one acids. (1994)

Some carboxylic acids of N(3)-pyrazole substituted 1,2,3-benzotriazin-4-(3H)-ones and- quinazolin-4-(3H)-ones were prepared and tested for the inhibitory property of 3 alpha-hydroxysteroid dehydrogenase of rat liver cytosol. The results indicated that the degree of inhibition can be used to predict the antiinflammatory potency of the compounds described.
VLSI-architecture for enabling multiple parallel associative searches with standard SRAM macros (2009)

This paper presents a ternary multi-ported content addressable memory (CAM) architecture utilizing asynchronous multiple search-operation technology, aiming at efficient high throughput of associative-search operations. The asynchronous multiple search-operation technology adopts a Flexible Multi-ported Content Addressable Memory (FMCAM) architecture, which is reported. The proposed ternary multi-ported CAM architecture achieves a fast associative table-lookup solution for high-speed routing applications, such as IP packet forwarding and effectively realizes a Ternary Flexible Multi-ported Content Addressable Memory which we refer to as TFMCAM in this paper. The main novel points of the architecture are simultaneous multiple associative-search operations and a high implementation-yield ratio. The TFMCAM can fully exploit the conventional SRAM memory architecture in comparison to the conventional TCAM architecture. Furthermore, the TFMCAM architecture realizes the necessary background table maintenance function without preventing the associative-search operation. For verifying the effectiveness of the TFMCAM architecture, ASIC implementation results are evaluated in this paper.

A flashlamp-pumped highly efficient 0.1 at. % Cr3+ and 1.0 at. % Nd3+ codoped Y3Al5O12 ceramic laser was demonstrated. A 10.4 J output energy at 1064 nm was obtained, with a laser efficiency of 4.9%. The laser efficiency of the Cr3+ and Nd3+ codoped Y3Al5O12 ceramic rod was found to be more than twofold that of a 1.0 at. % Nd3+-doped Y3Al5O12 ceramic rod.
T Wave Alternans as a Predictor of Spontaneous Ventricular Tachycardia in a Canine Model of Sudden Cardiac Death (2002)

T wave alternans often occurred immediately before the onset of VT in dogs with myocardial infarction, complete AV block, and nerve growth factor infusion to the left stellate ganglion. Increased sympathetic activity might be responsible for the occurrence of the T wave alternans.
NEMO: A New Implicit-Connection-Graph-Based Gridless Router With Multilayer Planes and Pseudo Tile Propagation (2007)

The implicit-connection-graph-based router is superior to the tile-based router in terms of routing graph construction and point querying. However, the implicit connection graph has a higher degree of routing graph complexity. In this paper, a new multilayer implicit-connection-graph-based gridless router called NEMO is developed. Unlike the first implicit-connection-graph-based router that embeds all routing layers onto a routing plane, NEMO constructs a routing plane for each routing layer. Additionally, each routing plane comprises tiles, not an array of grid points with their connecting edges, and consequently, the complexity of the routing problem decreases. Each grid point then represents exactly one tile or its left-bottom corner such that a tile query is equivalent to any point query inside the queried tile, and a grid maze becomes tile propagation. Furthermore, to accelerate path search, continuous space tiles are combined as a pseudo maximum horizontally or vertically stripped tile. Experimental results reveal that NEMO conducts a point-to-point path search around ten times faster than the implicit-connection-graph-based router. General-purpose routing by NEMO also improves routing performance by approximately 1.69times-55.82 times, as compared to previously published works based on a set of commonly used MCNC benchmark circuits
Thermomicrocapillaries as temperature biosensors in single cells (2013)

Temperature is an important physical parameter in biology and its deviation from optimum can cause damage in biosystems. Thermocouples based on the Seebeck effect can be structured on glass microcapillaries to obtain thermomicrocapillaries (TMCs) usable in a micromanipulation setup. The suitability of the setup was proven by monitoring the temperature increase upon illumination of leaves and single cells following insertion of the TMC. The increase was 1.5 K in green tissue and 0.75 K in white leaf sections due to lower absorption. In single cells of trichomes, the increase was 0.5 K due to heat dissipation to the surrounding air.
Throughput improvement scheme in multi-code CDMA (1998)

In multi-code CDMA, there is no self-interference among the sub-codes of a single user. By taking advantage of this property, the authors propose a new scheduling scheme to improve throughput, and derive the system throughputs of two cases with the proposed scheme applied and not applied. Analysis results show that the proposed scheme considerably improves the system throughput.
Recognition and envelope translocation of chloroplast preproteins (2005)

Plastids are a diverse group of plant organelles that perform essential functions including important steps in many biosynthetic pathways. Chloroplasts are the best characterized type of plastid, and constitute the site of oxygenic photosynthesis in plants, a process essential to all higher life forms. It is well established that the majority (>90%) of chloroplast proteins are nucleus-encoded and must be post-translationally imported into these envelope-bound compartments. Most nucleus-encoded chloroplast proteins are translated in precursor form on cytosolic ribosomes, targeted to the chloroplast surface, and then imported across the double-membrane envelope by translocons in the outer and inner envelope membranes of the chloroplast, termed TOC and TIC, respectively. Recently, significant progress has been made in our understanding of how proteins are targeted to the chloroplast surface and translocated across the chloroplast envelope into the stroma. Evidence suggesting the existence of multiple import pathways at the outer envelope membrane for different classes of precursor proteins has been presented. These pathways appear to utilize similar TOC complexes equipped with different combinations of homologous GTPase receptors, providing preprotein recognition specificity.
Stability and nonreactivity of ergothioneine in human erythrocytes studied by <sup>1</sup>H NMR (1993)

The N(CH3)3 resonance of ergothioneine in 1H spin-echo Fourier transform (SEFT) NMR spectra of red blood cells is usually a large singlet and it has been common practice to use this apparently unchanging resonance as an intensity reference. Recently, Reglinski et al. (Magn. Reson. Med. 6, 217-223 (1988)) have questioned this practice, reporting changes seen in the resonance in response to oxidative stress induced by arsenicals. We propose that the changes in the ergothioneine resonance that were reported are artifacts due to alterations in osmolality and magnetic susceptibility induced by the addition of nonisotonic solutions to red blood cell suspensions. These factors change the specific intensity of the intracellular resonances of all compounds. Ergothioneine was observed not to take part in any chemical reactions with arsenicals in free solution or in intact erythrocytes, and we conclude that ergothioneine may still be used as an internal intensity reference in 1H SEFT NMR spectra, bearing in mind the above physical factors.
Photon beam description in PEREGRINE for Monte Carlo dose calculations (1997)

Goal of PEREGRINE is to provide capability for accurate, fast Monte Carlo calculation of radiation therapy dose distributions for routine clinical use and for research into efficacy of improved dose calculation. An accurate, efficient method of describing and sampling radiation sources is needed, and a simple, flexible solution is provided. The teletherapy source package for PEREGRINE, coupled with state-of-the-art Monte Carlo simulations of treatment heads, makes it possible to describe any teletherapy photon beam to the precision needed for highly accurate Monte Carlo dose calculations in complex clinical configurations that use standard patient modifiers such as collimator jaws, wedges, blocks, and/or multi-leaf collimators. Generic beam descriptions for a class of treatment machines can readily be adjusted to yield dose calculation to match specific clinical sites.
Identification of cytotoxic T‐lymphocyte epitope(s) and its agonist epitope(s) of a novel target for vaccine therapy (PAGE4) (2007)

PAGE4 is an X chromosome-linked cancer testis antigen and is a potential new tumor-associated antigen that is overexpressed in prostate and uterine cancers. The purpose of this study was to identify a human CTL epitope and a corresponding agonist epitope of PAGE4 to determine if PAGE4 is a potential target for vaccine-mediated immunotherapy against PAGE4-expressing tumors. A class I PAGE4 epitope was identified with a high level of binding to HLA-A2. PAGE4 peptide-pulsed dendritic cells were then used to generate human PAGE4-specific T-cell lines. Further studies demonstrated the generation of an enhancer agonist epitope. Compared with the native peptide, the agonist (i) bound to HLA-A2 molecules at lower peptide concentrations, (ii) demonstrated a higher stability of the peptide HLA-A2 complex, (iii) induced higher levels of production of IFN-gamma, Granzyme B, TNF-alpha, IL-2 and lymphotactin by PAGE4-specific T-cell lines and (iv) T-cell lines generated against the agonist peptide were more efficient to lyse HLA-A2 human tumor cells expressing native PAGE4. The studies reported here are the first to describe a PAGE4 CTL epitope and its agonist epitope, and thus identify PAGE4 as a potentially useful target for vaccine-mediated therapy of prostate cancer.

Molecular Organogels. Soft Matter Comprised of Low-Molecular-Mass Organic Gelators and Organic Liquids (2006)

This Account presents recent advances in understanding how and why dilute solutions/sols of low-molecular-mass organic gelators (LMOGs) undergo microscopic phase separation to form self-assembled fibrillar networks in molecular organogels. Concepts are illustrated structurally at the subnanometer (molecular) to several millimeter (bulk) length scales and dynamically over time scales that follow the assembly of supersaturated solutions/sols into gel phases. Examples include both structurally complicated (ALSmolecules with aromatic, linking, and steroidal groups) and simple (n-alkanes or n-alkanes along whose chains a hetero-group has been inserted) LMOGs in a wide range of organic liquids.

SMAA-2: Stochastic Multicriteria Acceptability Analysis for Group Decision Making (2001)

Stochastic multicriteria acceptability analysis (SMAA) is a multicriteria decision support method for multiple decision makers in discrete problems. In SMAA, the decision makers need not express their preferences explicitly or implicitly. Instead, the method is based on exploring the weight space in order to describe the valuations that would make each alternative the preferred one. Inaccurate or uncertain criteria values are represented by probability distributions from which the method computes confidence factors describing the reliability of the analysis. In this paper we introduce the SMAA-2 method, which extends the original SMAA by considering all ranks in the analysis. In situations where the “elitistic” SMAA may assess large acceptability only for extreme alternatives without sufficient majority support, the more holistic SMAA-2 analysis can be used to identify good compromise candidates. The results are presented graphically. We consider also situations where partial preference information is available. We demonstrate the new method using a real-life decision problem.
Chia Seeds (Salvia Hispanica L.): An Overview—Phytochemical Profile, Isolation Methods, and Application (2019)

Chia (<i>Salvia hispanica</i> L.) is a small seed that comes from an annual herbaceous plant, <i>Salvia hispanica</i> L. In recent years, usage of Chia seeds has tremendously grown due to their high nutritional and medicinal values. Chia was cultivated by Mesopotamian cultures, but then disappeared for centuries until the middle of the 20th century, when it was rediscovered. Chia seeds contain healthy ω-3 fatty acids, polyunsaturated fatty acids, dietary fiber, proteins, vitamins, and some minerals. Besides this, the seeds are an excellent source of polyphenols and antioxidants, such as caffeic acid, rosmarinic acid, myricetin, quercetin, and others. Today, chia has been analyzed in different areas of research. Researches around the world have been investigating the benefits of chia seeds in the medicinal, pharmaceutical, and food industry. Chia oil is today one of the most valuable oils on the market. Different extraction methods have been used to produce the oil. In the present study, an extensive overview of the chemical composition, nutritional properties, and antioxidant and antimicrobial activities, along with extraction methods used to produce chia oil, will be discussed.
Predictive-Corrective Networks for Action Detection (2017)

While deep feature learning has revolutionized techniques for static-image understanding, the same does not quite hold for video processing. Architectures and optimization techniques used for video are largely based off those for static images, potentially underutilizing rich video information. In this work, we rethink both the underlying network architecture and the stochastic learning paradigm for temporal data. To do so, we draw inspiration from classic theory on linear dynamic systems for modeling time series. By extending such models to include nonlinear mappings, we derive a series of novel recurrent neural networks that sequentially make top-down predictions about the future and then correct those predictions with bottom-up observations. Predictive-corrective networks have a number of desirable properties: (1) they can adaptively focus computation on surprising frames where predictions require large corrections, (2) they simplify learning in that only residual-like corrective terms need to be learned over time and (3) they naturally decorrelate an input data stream in a hierarchical fashion, producing a more reliable signal for learning at each layer of a network. We provide an extensive analysis of our lightweight and interpretable framework, and demonstrate that our model is competitive with the two-stream network on three challenging datasets without the need for computationally expensive optical flow.
