Structural and Electrochemical Investigations of the High Fluoride Affinity of Sterically Hindered 1,8-Bis(boryl)naphthalenes (2006)

The reaction of 10-bromo-9-oxa-10-boraanthracene with the tetrakis(tetrahydrofuran)lithium salt of dimesityl-1,8-naphthalenediylborate in diethyl ether affords 1-(dimesitylboryl)-8-(10'-bora-9'-oxaanthryl)naphthalene (2). This diborane reacts with [Me3SiF2][S(NMe2)3)] to afford the anionic complex [2-mu2-F]-, which has been isolated as a [S(NMe2)3]+ salt. The cyclic voltammograms of diborane 2 as well as 1-(dimesitylboryl)-8-(10'-bora-9'-thiaanthryl)naphthalene (1) exhibit two reversible reductions at E(1/2) = -2.200 and -2.566 V (vs FcH/FcH+) for 1 and E(1/2) = -2.248 and -2.620 V (vs FcH/FcH+) for 2 corresponding to the sequential reduction of the two boron centers. These two waves simultaneously disappear upon fluoride addition, thus indicating the formation of fluoride chelate complexes [1-mu2-F]- and [2-mu2-F]-. To identify the origin of the high fluoride affinity displayed by these diboranes, the structures of 2 and [2-mu2-F]- have been studied experimentally and computationally. The crystallographic studies show that the structure of 2 is distorted, thus indicating the presence of important steric repulsions between the neighboring boryl moieties. By contrast, the structure of the anionic complex [2-mu2-F]- is much more sterically relaxed than that of 2, as indicated by a reduction of the B-B distance from 3.279(4) A in 2 to 2.922(7) A in [2-mu2-F]-. The structural results suggest that the high fluoride affinity displayed by 2 results, at least in part, from the relief of steric repulsions induced by fluoride binding. Finally, the nature of the bonding as well as the strength of the interactions involved in the B-F-B bridge of [2-mu2-F]- has been studied using density functional theory calculations and Atoms-In-Molecules analyses. These calculations indicate that the enthalpic gain associated with the formation of two B-F bonds in [2-mu2-F]- only amounts to a fraction of the energy of a terminal B-F bond. These calculations also suggest that the relief of steric repulsions induced by fluoride binding in 2 may contribute to the high fluoride affinity of these types of molecules.

Multiple-stream instabilities and soliton turbulence in photonic plasma (2008)

We demonstrate weak and strong regimes of optical spatial turbulence by considering the nonlinear interaction of three partially coherent spatial beams. The geometry represents a multiple bump-on-tail instability, allowing an interpretation of nonlinear statistical light as a photonic plasma. For weak nonlinearity, we observe instability competition and sequential flattening of the bumps in momentum space, with no observable variations in position-space intensity. For strong nonlinearity, intensity modulations appear and the triple-hump spectrum merges into a single-peaked profile with an algebraic ${k}^{\ensuremath{-}2}$ inertial range. This spectrum, with its associated modulations, is a definitive observation of soliton, or Langmuir, turbulence.
Modulating the Cascade architecture of a minimal Type I-F CRISPR-Cas system (2016)

Shewanella putrefaciens CN-32 contains a single Type I-Fv CRISPR-Cas system which confers adaptive immunity against bacteriophage infection. Three Cas proteins (Cas6f, Cas7fv, Cas5fv) and mature CRISPR RNAs were shown to be required for the assembly of an interference complex termed Cascade. The Cas protein-CRISPR RNA interaction sites within this complex were identified via mass spectrometry. Additional Cas proteins, commonly described as large and small subunits, that are present in all other investigated Cascade structures, were not detected. We introduced this minimal Type I system in Escherichia coli and show that it provides heterologous protection against lambda phage. The absence of a large subunit suggests that the length of the crRNA might not be fixed and recombinant Cascade complexes with drastically shortened and elongated crRNAs were engineered. Size-exclusion chromatography and small-angle X-ray scattering analyses revealed that the number of Cas7fv backbone subunits is adjusted in these shortened and extended Cascade variants. Larger Cascade complexes can still confer immunity against lambda phage infection in E. coli Minimized Type I CRISPR-Cas systems expand our understanding of the evolution of Cascade assembly and diversity. Their adjustable crRNA length opens the possibility for customizing target DNA specificity.
A rapid and convenient technique for measuring the rate of protein synthesis in tissues by injection of [3H]phenylalanine (1980)

A rapid procedure for measuring the specific radioactivity of phenylalanine in tissues was developed. This facilitates the accurate determination of rates of protein synthesis in a wide range of tissues by injection of 150 mumol of L-[4-(3)H]phenylalanine/100 g body wt. The large dose of amino acid results in a rapid rise in specific radioactivity of free phenylalanine in tissues to values close to that in plasma, followed by a slow but linear fall. This enables the rate of protein synthesis to be calculated from measurements of the specific radioactivity of free and protein-bound phenylalanine in tissues during a 10 min period after injection of radioisotope.
New Solid State Power Amplifiers Design Using Large Signal S Parameters (2001)

A new method related to power amplifier design is described in this paper. Based on Large signal S parameters, defined as function of the input power, coupled with the Real Frequency technique, this approach determines the optimum load impedance for maximum added power.
Choroidal thickness changes during altered eye growth and refractive state in a primate. (2000)

In marmosets, the thickness of the choroid increases during postnatal eye growth. Superimposed on this developmental increase in choroidal thickness there are changes in thickness that are correlated with the induced changes in eye size. These changes are small (<50 microm) in comparison with those observed in the chick, contributing to less than a diopter change in refractive error.
The murine homolog of human Nectin1δ serves as a species nonspecific mediator for entry of human and animal αherpesviruses in a pathway independent of a detectable binding to gD (2000)

The full-length cDNA of the murine homolog of human nectin1delta (mNectin1delta), also known as human poliovirus receptor related 1 (PRR1) or herpesvirus entry mediator C, was cloned and showed a >90% identity with its human counterpart. mNectin1delta is expressed in some murine cell lines, exemplified by NIH 3T3 and L cells, and in murine tissues. It mediates entry of an extended range of herpes simplex virus (HSV) strains, porcine pseudorabies virus (PrV), and bovine herpesvirus 1. A soluble form of the mediator blocked infectivity in mNectin1delta and human nectin1delta (hNectin1delta)-expressing cells, suggesting a physical interaction of the mediator with virions. The higher concentrations of soluble mNectin1 required to block infectivity relative to soluble hNectin1 suggest that the target of the two molecules is not identical. Entry of HSV, but not PrV, was blocked by soluble mNectin1delta in NIH 3T3 and L cells. Two features were unexpected. First, soluble mNectin1delta failed to physically interact with HSV glycoprotein D (gD) at a detectable level, although it interacted physically with virions. Second, coexpression of mNectin1delta and HSV gD did not restrict HSV or PrV infection, whereas coexpression of hNectin and gD did restrict infection, suggesting that mNectin1delta fails to be sequestered by HSV gD. We conclude that mNectin1delta serves as a species-nonspecific mediator for entry of the human and animal alphaherpesviruses. This activity, at least for HSV, is independent of a detectable binding to gD.

Metal Resistivity Measuring Device (2023)

An eddy current device is designed for detecting discontinuities in metal samples. Alternate short and long duration pulses are inductively applied to a metal sample via the outer coil of a probe. The lorg pulses give a resultant signal from the metal sample responsive to probe-tosample spacing and discontinuities with the sample, and the short pulses give a resultant signal responsive only to probe-to-sample spacing. The inner coil of the probe detects the two resultant signals and transmits them to a separation network where the two signals are separated. The two separated signals are then transmitted to a compensation network where the detected signals due to the short pulses are used to compensate for variations due to probeto-sample spacing contained in the detected signals from the long pulses. Thus a resultant signal is obtained responsive to discontinuities within the sample and independent of probe-to- sample spacing.
Illumination-free gaze estimation method for first-person vision wearable device (2011)

Gaze estimation is a key technology to understand a person's interests and intents, and it is becoming more popular in daily situations such as driving scenarios. Wearable gaze estimation devices are use for long periods of time, therefore non-active sources are not desirable from a safety point of view. Gaze estimation that does not rely on active source, is performed by locating iris position. To estimate the iris position accurately, most studies use ellipse fitting in which the ellipse is defined by 5 parameters(position (x,y), rotation angle, semi-major axis and semi-minor axis). We claim that, for iris position estimation, 5 parameters are redundant because they might be influenced by non-iris edges. Therefore, we propose to use 2 parameters(position) introducing a 3D eye model(the transformation between eye and camera coordinate and eyeball/iris size). Given 3D eye model, projected ellipse that represents iris shape can be specified only by position under weak-perspective approximation. We quantitatively evaluate our method on both iris position and gaze estimation. Our results show that our method outperforms other state-of-the-art's iris estimation and is competitive to commercial product that use infrared ray with respect to both accuracy and robustness.
Membrane topology and mutational analysis of the TolQ protein of Escherichia coli required for the uptake of macromolecules and cell envelope integrity (1994)

TolQ is a 230-amino-acid protein required to maintain the integrity of the bacterial envelope and to facilitate the import of both filamentous bacteriophage and group A colicins. Cellular fractionation experiments showed TolQ to be localized to the cytoplasmic membrane. Bacteria expressing a series of TolQ-beta-galactosidase and TolQ-alkaline phosphatase fusion proteins were analyzed for the appropriate enzyme activity, membrane location, and sensitivity to exogenously added protease. The results are consistent with TolQ being an integral cytoplasmic membrane protein with three membrane-spanning regions. The amino-terminal 19 residues as well as a small loop in the 155 to 170 residue region appear exposed in the periplasm, while the carboxy terminus and a large loop after the first transmembrane region are cytoplasmic. Amino-terminal sequence analysis of TolQ purified from the membrane revealed the presence of the initiating formyl methionine group, suggesting a rapid translocation of the amino-terminal region across the cytoplasmic membrane. Analysis of various tolQ mutant strains suggests that the third transmembrane region as well as parts of the large cytoplasmic loop are necessary for activity.
A sound algorithm for region-based image retrieval using an index (2002)

Region-based image retrieval systems aim to improve the effectiveness of content-based search by decomposing each image into a set of "homogeneous" regions. Thus, similarity between images is assessed by computing similarity between pairs of regions and then combining the results at the image level. We propose the first provably sound algorithm for performing region-based similarity search when regions are accessed through an index. Experimental results demonstrate the effectiveness of our approach, as also compared to alternative retrieval strategies.

Diamond MESFET using ultrashallow RTP boron doping (1991)

A diamond p-type depletion-mode MESFET was fabricated using a novel doping technique to drive in and activate boron in type IIa diamond. An ultrashallow p-doped channel of less than 500 AA was created by this rapid-thermal-processing (RTP) solid-state diffusion using cubic boron nitride as the dopant source. The MESFET was observed to pinch off at high positive gate bias, and reverse-bias leakage was below 10/sup -12/ A at +5 V. The ultrashallow channel depth is believed to be a critical factor in obtaining excellent device modulation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Intrathoracic and abdominal pressure variations as an efficient method for cardiopulmonary resuscitation: Studies in dogs compared with computer model results (1985)

Intrathoracic pressure variations are currently proposed as the main flow-generation mechanisms in standard and modified cardiopulmonary resuscitation (CPR) techniques. A method of changing pressure within the thorax and abdomen without any degree of heart compression was developed and tested in dogs. Intrathoracic and abdominal pressure waves were induced by cyclic inflation and deflation of the lungs and of perithoracic and periabdominal balloons. Various modes of CPR, depending on the rate of cycling, the use of a periabdominal balloon inflation, and a delay between the abdominal and thoracic pressure waves, were studied during ventricular fibrillation. During artificial systole (high intrathoracic pressure phase), the pressure which developed in the right ventricle (96.7 +/- 20.5 mmHg) was higher than the pressure in the aorta (89.3 +/- 20.5 mmHg, p less than 0.001). In artificial diastole (low intrathoracic pressure phase), the right ventricular pressure (11.7 +/- 2.6 mmHg) was lower than the aortic pressure (17.5 +/- 3.3 mmHg, p less than 0.001). The average flow in the carotid artery was 21.7 +/- 7.8 ml . min-1, which was 18 +/- 6% of the baseline carotid flow before CPR. Three different factors were found to improve the efficiency of CPR: periabdominal balloon inflation simultaneous with the intrathoracic pressure waves; increased frequency of the pressure waves from 60 to 100 cycles per minute; and inflation of the periabdominal balloon 50 to 100 ms before the thoracic balloon. Blood-gas and acid-base balance analysis during CPR revealed well-oxygenated arterial blood with a marked respiratory alkalosis and a slowly developing metabolic acidosis.(ABSTRACT TRUNCATED AT 250 WORDS)

Face recognition with biometric encryption for privacy-enhancing self-exclusion (2009)

Face recognition has been employed in various security-related applications such as surveillance, mugshot identification, e-passport, and access control. Despite its recent advancements, privacy concern is one of several issues preventing its wider deployment. In this paper, we address the privacy concern for a self-exclusion scenario of face recognition, through combining face recognition with a simple biometric encryption scheme called helper data system. The combined system is described in detail with focus on the key binding procedure. Experiments are carried out on the CMU PIE face database. The experimental results demonstrate that in the proposed system, the biometric encryption module tends to significantly reduce the false acceptance rate while increasing the false rejection rate.
The osteoblast: An insulin target cell controlling glucose homeostasis (2010)

The past five years have witnessed the emergence and discovery of unexpected functions played by the skeleton in whole-organism physiology. Among these newly described tasks is the role of bone in the control of energy metabolism, which is achieved through the secretion of osteocalcin, an osteoblasts-derived hormone regulating insulin secretion, insulin sensitivity, and energy expenditure. These initial findings raised several fundamental questions on the nature of insulin action in bone. Discoveries made independently by our two groups have provided answers recently to some of these questions. Through the analysis of mice lacking insulin receptor (InsR) only in osteoblasts, we found that insulin signaling in these cells favors whole-body glucose homeostasis. Importantly, this function of insulin signaling in osteoblasts was achieved through the negative regulation of osteocalcin carboxylation and bioavailability. Our studies also established that insulin signaling in osteoblasts was a positive regulator not only of postnatal bone acquisition but also of bone resorption. Interestingly, it appears that insulin signaling in osteoblasts induced osteocalcin activation by stimulating osteoclast activity. Indeed, the low pH generated during bone resorption is a sufficient means to decarboxylate osteocalcin. Our findings establish that the osteoblast is an important target used by insulin to control whole-body glucose homeostasis and identify bone resorption as the mechanism regulating osteocalcin activation.
Synthesis and properties of cationic resins derived from polyether/polyester‐modified epoxy resins (1992)

Abstract Four polyether and one polyester‐modified cationic resins were synthesized by reacting polyether/polyester‐modified epoxy resins with 2‐ethylhexanol‐blocked‐toluene diisocyanate (2‐EH‐blocked TDI) and diethanolamine and subsequently neutralizing the resins with acetic acid. Four different polyethers and one polycaprolactone diol (PCP) were used to react with epoxy resin to form polyether‐modified epoxy resins (1a–d) and polyester‐modified epoxy resin (1e). The extent of reaction of epoxy resin and polyether or polyester was evaluated by the change of epoxy equivalent weight and the gel permeation chromatography curve of the resulting product. Cationic resins were dissolved in suitable solvents and were mixed with deionized water to form emulsions. Some factors, such as pH value of emulsion, solvent content, and applied voltage affecting the emulsion and electrodeposition properties, were investigated. Cationic resins, prepared from PPG (#1000)‐modified epoxy resins, yielded a wider pH range of stable emulsion and also yielded deposited films with a pleasing appearance. PEG (#1000)‐modified cationic resins produced a higher deposition yield, but higher throwing power was obtained by deposition of the PCP (#530)‐modified cationic resins.
Integrated nutrient management in Dendrocalamus strictus (Roxb) Ness for quality seedling production (2014)

An experiment was laid out for quality seedling production of  Dendrocalamus strictus (Roxb) Ness in nursery at three levels of integrated nutrient management (INM) combinations viz N, P 2 O 5 and K 2 O (2.0, 1.25, 1.25; 1.5, 0.938, 0.938; 1.0, 0.625, 0.625 g kg -2 of soil) applied as urea, single super phosphate and muriate of potash along with FYM (500 g) and biofertilizers viz  VAM and  Azospirillum each @ 40, 20 g kg -2 of soil respectively and compared with unfertilized control. The results revealed that integration of 1.5 g N, 0.938 g of P 2 O 5 and 0.938 g of K 2 O kg -2 of soil supplemented with FYM (500g), VAM (40 g) and Azospirillum (20 g) significantly enhanced the growth parameters viz shoot length and number of leaves, root length, collar diameter, dry matter, volume index and quality index of D strictus seedlings over control.
Continuity conditions for envelope functions at semiconductor interfaces derived from the Bastard model (1987)

The envelope function approximation due to Bastard, which is widely used for the calculation of energy levels in quantum wells and superlattices, has been re-examined to check for consistency.This has been achieved by writing down the coupled differential equations obeyed by the envelope functions, and then treating the valence band envelope functions as the dependent variables.This is in contrast to the usual approach, where the conduction band envelope functions are treated as the dependent variables.The superlattice band structure is found to be identical for both approaches, and so the method gives consistent results.However, the boundary conditions on the valence band envelopes at a semiconductor interface are not the expected ones.The explicit form of the valence band envelope function boundary conditions at an interface are discussed in this paper.In the Bastard model, the freeelectron kinetic energy that appears in the k .p model that describes t h e semiconductors is neglected, and it is the neglect of this term that gives rise to t h e unusual boundary conditions on t h e valence band envelopes that are described in this work.
Effect of low numerical-aperture femtosecond two-photon absorption on (SU-8) resist for ultrahigh-aspect-ratio microstereolithography (2005)

We report the quantitative characterization and analysis on the solidification of SU-8, a chemically amplified near-ultraviolet ultrathick resist, based on two-photon-absorbed (TPA) near-infrared photopolymerization. The resolution of TPA photopolymerized SU-8 voxels and lines is studied as a function of laser-pulse energy, single-shot exposure time, and scanning speed. Two-photon microstereolithography using SU-8 as the matrix material was verified by the fabrication of SU-8 photoplastic structures with subdiffraction-limit resolution. We show that the nonlinear velocity dependence of TPA photopolymerization can be used as the shutter mechanism for disruptive three-dimensional (3D) lithography. This mechanism, when combined with low numerical-aperture optics is exploited for the rapid 3D microfabrication of ultrahigh-aspect-ratio (up to 50:1) photoplastic pillars, planes, and cage structures.
