bis(S-Acyl-2-thioethyl)esters of 2',3'-Dideoxyadenosine 5'-Monophosphate Are Potent Anti-HIV Agents in Cell Culture (1995)

Abstract It is shown that ddA bis(SATE)phosphotriesters have potent anti-HIV activity in cell culture. Thus, compared with the parent nucleoside, a decrease of 3 or 4 orders of magnitude was observed in the EC50 values for the bis(S-acetyl-2-thioethyl)phosphotriester derivative, which makes this compound as active as AZT.
Printed Electronics: Low‐Cost, Organic Light‐Emitting Electrochemical Cells with Mass‐Producible Nanoimprinted Substrates Made Using Roll‐to‐Roll Methods (Adv. Mater. Technol. 5/2017) (2017)

The roll-to-roll production of nanoimprinted corrugated substrates for light extraction is described by Yoshinori Nishikitani and co-workers in article number 1600293. Using self-assembled block copolymer films on glass and film substrates, the methods shows promise for mass producing a variety of luminous materials.
Fast algorithm for statistical phrase/accent command estimation based on generative model incorporating spectral features (2017)

An important challenge in speech processing involves extracting non-linguistic information from a fundamental frequency (F <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> ) contour of speech. We propose a fast algorithm for estimating the model parameters of the Fujisaki model, namely, the timings and magnitudes of the phrase and accent commands. Although a powerful parameter estimation framework based on a stochastic counterpart of the Fujisaki model has recently been proposed, it still had room for improvement in terms of both computational efficiency and parameter estimation accuracy. This paper describes our two contributions. First, we propose a hard expectation-maximization (EM) algorithm for parameter inference where the E step of the conventional EM algorithm is replaced with a point estimation procedure to accelerate the estimation process. Second, to improve the parameter estimation accuracy, we add a generative process of a spectral feature sequence to the generative model. This makes it possible to use linguistic or phonological information as an additional clue to estimate the timings of the accent commands. The experiments confirmed that the present algorithm was approximately 16 times faster and estimated parameters about 3% more accurately than the conventional algorithm.
Physicochemical Properties of EMPyrCl-ZnCl2 Melts and Electrodeposition of Molybdenum from the Equimolar Melt at 150.DEG.C. (2009)

A new molten salt system, N-ethyl-N-methylpyrrolidinium chloride (EMPyrCl)-ZnCl2, was investigated for the electrodeposition of molybdenum at intermediate temperature. A phase diagram was constructed for the EMPyrCl-ZnCl2 system, which shows the lowest melting point of 45°C at an equimolar composition. A thermal gravimetry indicated that thermal decomposition starts from 230°C for the equimolar melt. The viscosity and conductivity of the equimolar melt were 75 cP and 22 mS cm−1, respectively, at 150°C. The cathode limit of the equimolar melt was confirmed to be the deposition of metallic zinc by XRD analysis. A smooth metallic molybdenum film was electrodeposited on a nickel substrate by potentiostatic electrolysis at 0.01 V vs. Zn(II)/Zn in an equimolar melt containing MoCl5 (0.9 mol%) and KF (3.0 mol%) at 150°C.
NMR spectra of moganite and chalcedony (1994)

29 Si MAS NMR, 29 Si { 1 H} CP MAS NMR and 1 H MAS NMR spectra of the water-containing microcrystalline silica varieties chalcedony, moganite and three intermediate samples are reported. The 29 Si MAS NMR spectra give evidence that, unlike quartz, the silicon atoms occupy two symmetrically different sites in moganite. The 1 H MAS NMR spectra show signals of molecular water and four different species of silanol groups
The terminal web. A reevaluation of its structure and function. (1979)

The apical cytoplasm of epithelial cells of the small and large intestines has been examined by freeze-etch techniques as well as conventional and high voltage electron microscopy of sectioned material to gain a better understanding of the fine structural organization of the terminal web region. In the small intestine the terminal web exhibits a distinct stratification caused by the association of different sets of filaments with the three members of the junctional complex. Individual filaments of this network are closely associated with the sealing elements of the tight junctions, the surface of the core microfilament bundles, and the intermicrovillar plasma membrane. This region of the terminal web is the apical zone. The adherens zone appears as a band of interwoven filaments of two different diameters extending across the cytoplasm at the level of the intermediate junction. Within this region of the terminal web, individual 60-70 A actin-like filaments separate from the bundles of core microfilaments to interact with one another and with filaments of similar diameter from the zonula adherens. 100 A tonofilaments also contribute to the adherens zone, presumably stabilizing the orientation of the actin-like filaments. The basal zone which underlies the adherens zone consists of closely interwoven bundles of tonofilaments that are anchored to and interconnect the spot desmosomes. Within the large intestine the cytoplasmic microfilaments form a looser and less clearly stratified network which nevertheless retains the same basic organization found in the small intestine. Transmembrane linkers appear to originate within the cytoplasmic plaques of the spot desmosomes, pass through the plasma membranes, and meet in a staggered configuration in the intercellular space; these linkers may thus mediate the actual mechanical coupling between the cytoskeletal networks of tonofilament bundles of adjacent cells. This integrated system of cytoplasmic filaments and intercellular junctions endows the apical cytoplasm with both the flexibility and the stability necessary for the normal functioning of the epithelium.
Liquid crystalline networks from 1,4‐benzenedicarboxylic acid bis(4‐cyanatomethylphenyl) ester (1997)

Abstract The phase behaviour and curing reaction of 1,4‐benzenedicarboxylic acid bis(4‐cyanatomethylphenyl) ester (LC dicyanate) as well as the mechanical properties of the LC network were examined. The overall reaction kinetics were found to be first order with an activation energy of 67.5 kJ/mol similar to many conventional dicyanate monomers. Gelation was detected by viscoelastic measurements and occurred at a conversion of ≈0.5. These results suggest that the topology of the network formed in the LC dicyanate system was the same as non‐LC dicyanates such as 2,2‐bis(cyanatophenyl)propane. The onset of the mesophase was found to start at a conversion of ≈0.06 and end at a conversion of ≈0.20, independent of the curing temperature (180–280°C). This observation indicates that small clusters comprising a small oligomer (mainly trimer) surrounded by 6–7 monomers dominate formation of the mesophase which possesses a clearing temperature above at least 280°C. Competition between liquid crystalline order and high crosslink density resulted in a large free volume in the glassy state. This large free volume strongly affects mechanical behavior as well as the glass transition temperature of the LC network.

Compton scattering driven by intense quantum light (2023)

Compton scattering is a cornerstone of quantum physics, describing the fundamental electron-photon interaction. Inverse Compton scattering can create attosecond x-ray pulses by high-intensity lasers driving free electrons. So far, in all theory and experiments, the observables of Compton scattering and its generalizations could be described by treating the driving electromagnetic field classically. Motivated by advances in the generation of squeezed light with high intensity, we consider driving the Compton effect with nonclassical light. We develop a framework to describe the nonperturbative interaction of a charged particle with driving fields of an arbitrary quantum light state. We obtain analytical results for the Compton emission spectrum when driven by intense thermal and squeezed vacuum states, showing noticeably broader emission spectra relative to a classical drive, thus reaching higher emission frequencies for the same average intensity. We envision quantum light properties such as squeezing and entanglement as degrees of freedom to control various radiation phenomena.

Eight-Wavelength-Switchable Narrow Linewidth Erbium-Doped Fiber Laser Based on Cascaded Superimposed High-Birefringence Fiber Bragg Grating (2022)

A narrow-linewidth eight-wavelength-switchable erbium-doped fiber laser is proposed, and its performance is demonstrated. A cascaded superimposed high-birefringence fiber Bragg grating is used to determine the lasing wavelengths. The combination of a Fabry–Pérot filter and a single-coupler ring is adopted to achieve the single-longitudinal-mode (SLM) oscillation. By introducing the enhanced polarization-hole-burning effect to suppress the gain competition between different wavelength lasers, the stable lasing output is guaranteed. When the pump power is 200 mW, by adjusting the polarization controller to balance the gain and loss in the laser cavity, 24 switchable lasing modes are achieved, including 8 single-wavelength operations and 16 dual-wavelength operations with orthogonal polarization states. For single-wavelength operations, every laser is in the SLM lasing state, with a high stabilized optical spectrum, a linewidth of approximately 1 kHz, an optical signal-to-noise ratio (OSNR) as high as 73 dB, a relative intensity noise of less than −150 dB/Hz, and very good polarization characteristics. For dual-wavelength operations, the lasers also have a stable spectrum and an OSNR as high as 65 dB. The proposed fiber laser has a wide range of applications, including long-haul coherence optical communication, optical fiber sensing, and dense wavelength-division-multiplexing.
Monofunctional Stealth Nanoparticle for Unbiased Single Molecule Tracking Inside Living Cells (2014)

On the basis of a protein cage scaffold, we have systematically explored intracellular application of nanoparticles for single molecule studies and discovered that recognition by the autophagy machinery plays a key role for rapid metabolism in the cytosol. Intracellular stealth nanoparticles were achieved by heavy surface PEGylation. By combination with a generic approach for nanoparticle monofunctionalization, efficient labeling of intracellular proteins with high fidelity was accomplished, allowing unbiased long-term tracking of proteins in the outer mitochondrial membrane.
Compensatory remodeling of coronary microvasculature maintains shear stress in porcine left-ventricular hypertrophy (2012)

The present findings quantify the structural and functional remodeling in the entire LCx arterial tree in response to LVH, which reflect heterogeneity in vascular morphometry and hemodynamics from small to large vessels. These conclusions enhance our understanding of compensatory vascular remodeling in LVH of pediatric heart.
Hydrazine reduction of transition-metal oxides (1987)

The surface interactions of the thermodynamically stable oxides of the firstrow transition metals with hydrazine, N2H4, have been assessed by X-ray photoelectron spectroscopy (X.p.s.), and the observed reactivity explained on the basis of the oxides' thermodynamic and acid–base properties. Microgravimetry, transmission electron microscopy (TEM) and X.p.s. studies of copper(II) oxide (CuO) reduction by hydrazine indicate morphological changes associated with enhanced reactivity. Comparison of hydrazine and hydrogen reduction treatments shows that CuO reduction by hydrazine is more spontaneous and provides a greater increase in surface area than does hydrogen at similar reaction conditions.
Comparison of interior and surface PM machines equipped with fractional-slot concentrated windings for hybrid traction applications (2011)

Electric drive systems, which include electric machines and power electronics, are a key enabling technology for advanced vehicle propulsion systems that reduce the petroleum dependence of the ground transportation sector. To have significant effect, electric drive technologies must be economical in terms of cost, weight, and size while meeting performance and reliability expectations. This paper will provide details of the design, analysis and testing of two permanent magnet (PM) machines that were developed to meet the FreedomCar 2020 specifications. The first machine is an Interior PM (IPM) machine and the second machine is a surface PM (SPM) machine. Both machines are equipped with fractional-slot concentrated windings (FSCW). The goal of the paper is to provide a quantitative assessment of how achievable this set of specifications is as well as a comparison with the state of the art. The paper will also quantitatively highlight the tradeoffs between IPM and SPM FSCW machines especially in the context of traction applications.
Nonlinear and Nonparametric Regression and Instrumental Variables (2004)

We consider regression when the predictor is measured with error and an instrumental variable (IV) is available. The regression function can be modeled linearly, nonlinearly, or nonparametrically. Our major new result shows that the regression function and all parameters in the measurement error model are identified under relatively weak conditions, much weaker than previously known to imply identifiability. In addition, we exploit a characterization of the IV estimator as a classical “correction for attenuation” method based on a particular estimate of the variance of the measurement error. This estimate of the measurement error variance allows us to construct functional nonparametric regression estimators making no assumptions about the distribution of the unobserved predictor and structural estimators that use parametric assumptions about this distribution. The functional estimators uses simulation extrapolation or deconvolution kernels and the structural method uses Bayesian Markov chain Monte Carlo. The Bayesian estimator is found to significantly outperform the functional approach.
Localisation of presenilin 2 in human and rodent pancreatic islet β-cells; Met239Val presenilin 2 variant is not associated with diabetes in man (1999)

Mutations in presenilin 1 and 2 are causative factors for early onset familial Alzheimer's disease and possible roles for presenilins include protein trafficking, regulation of apoptosis and/or calcium homeostasis. Presenilin 2 mRNA is expressed in brain, muscle and pancreas but the role of pancreatic presenilin 2 and its relationship to diabetes are unknown. Presenilin 2 immunoreactivity was localised in human and rodent pancreas to islet cells and found in granules of beta-cells. Presenilin 2 was identified in primitive islet and duct cells of human foetal pancreas and in proliferating exocrine duct cells in human pancreatitis but not found in islet amyloid deposits in Type 2 diabetic subjects. Full length, approximately 50 kDa, and the approximately 30 kDa N-terminal fragment of presenilin 2 were identified by western blotting in extracted rodent pancreas but only the 30 kDa fragment was detected in mouse islets and human insulinoma. Post-mortem pancreatic morphology was normal in a subject with the presenilin 2 Met239Val variant and early onset familial Alzheimer's disease. Oral glucose tolerance tests on subjects with the presenilin 2 Met239Val mutation unaffected by early onset familial Alzheimer's disease (mean age 35 years) and on their first-degree relatives without the mutation demonstrated no evidence of glucose intolerance or increased proinsulin secretion. PS2 is a novel &bgr;-cell protein with potential roles in development or protein processing but pancreatic islet structure and function appear to be unaffected by the Met239Val mutation.

Rate-distortion-efficient video compression using a 3-D head model (2003)

In this paper we combine model-based video synthesis with block-based motion-compensated prediction (MCP). Two frames utilized for prediction where one frame is the previous decoded one and the other frame is provided by a model-based coder. The approach is integrated into an H.263-based video codec. Rate-distortion optimization is employed for the coding control. Hence, the coding efficiency does not decrease below H.263 even if the model based coder cannot describe the current scene. On the other hand, if the objects in the scene correspond to the model-based coder, significant gains in coding efficiency can be obtained compared to TMN-10, the test model of the H.263 standard. This is verified by experiments with natural head-and-shoulder sequences. Bit-rate savings of about 35% are achieved at equal average PSNR. When encoding at equal bit-rate, significant improvements in terms of subjective quality are visible.
Protease Expression Colocalizes to Regions of Abdominal Aortic Expansion and Stiffening in a Murine Aneurysm Model (2008)

Abdominal aortic aneurysm (AAA) is a complex disease defined as a pathological dilation of the vessel wall to larger than 150% of normal. Although the poor clinical outcomes associated with this disease are well known, a detailed understanding of the underlying mechanisms that lead to AAA development and expansion remains elusive. The purpose of this study was to determine if areas of increased protease expression correspond to locations of aortic stiffening and enlargement in a commonly used mouse model [1].
Deconvolution by thresholding in mirror wavelet bases (2003)

The deconvolution of signals is studied with thresholding estimators that decompose signals in an orthonormal basis and threshold the resulting coefficients. A general criterion is established to choose the orthonormal basis in order to minimize the estimation risk. Wavelet bases are highly sub-optimal to restore signals and images blurred by a low-pass filter whose transfer function vanishes at high frequencies. A new orthonormal basis called mirror wavelet basis is constructed to minimize the risk for such deconvolutions. An application to the restoration of satellite images is shown.
Plasma Assisted Diffusion in Porous Materials: Experiments, Modeling and Applications (2012)

Plasma sputtering deposition of platinum on porous substrates is a relevant way for building high performance catalytic thin films. The knowledge and control of platinum density adsorbed in the porous medium, during deposition, are of primary importance. We show that the experimental concentration depth profiles originate from a superdiffusion phenomenon. Moreover experimental results are well described by a classical porous-fractal diffusion model, for which diffusion coefficient is also time-dependent, even if such a model does not include the proper physical mechanisms.
Prevalence of Production of Virus‐Specific Interferon‐γ among Seronegative Hepatitis C–Resistant Subjects Reporting Injection Drug Use (2004)

This report describes subjects who were highly likely to have been repeatedly exposed to hepatitis C virus (HCV) through injection drug use and who remained negative for anti-HCV antibody. Production of virus-specific interferon- gamma by peripheral blood mononuclear cells was seen in the majority of subjects (72%) and was associated with higher-risk behavior. For 92% of the subjects, results of recombinant immunoblot assays demonstrated faint bands against nonstructural proteins. The immune responses described are likely to have been primed and maintained by episodes of subclinical infection without classic seroconversion and may indicate a hepatitis C-resistant phenotype. Vaccine strategies to mimic this response may provide protection against persistent HCV infection.
