Effect of pH and ionic strength on the binding of bivalent cations to β-casein (1988)

The binding capacity of (3-casein for Ca 2 +, Mg 2 +, Mn 2 +, Zn 2 +, Cu 2 +, Fe 2 + was studied at various pHs (from 8.00 to 5.00) and different ionie strengths (about 0, 0.05, 0.10).
Electrocaloric Effects in Some Ferroelectric and Antiferroelectric Pb(Zr, Ti)O3 Compounds (1968)

Variations of sample temperature arising from the electrocaloric effect, antiferroelectric to ferroelectric transitions, and hysteresis-loss heating have been recorded together with the hysteresis loops for four different ceramic ferroelectrics near room temperature. Both the electric-field dependence and the temperature dependence of the electrocaloric effect were accurately predicted by the usual thermodynamic expression for the effect. Values for the heat capacity and the pyroelectric constant were also obtained from the data. The sample temperature of one composition which becomes antiferroelectric under zero applied field near 40°C was monitored at various temperatures as antiferroelectric to ferroelectric transitions were forced by an electric field. Above 55°C, the temperature change at the transition could be fitted with a theory originally developed for the field-enforced antiferroelectric to ferroelectric transition in PbZrO3.
Crosslinking of chitosan fibers with dialdehydes: Proposal of a new reaction mechanism (1999)

A highly deacetylated chitosan from shrimp with a degree of deacetylation of 95.28 ± 3.03% was prepared and spun into a monofilament fiber using a solution of 4% (w/v) chitosan in 4% (v/v) aqueous acetic acid. Samples of the spun fibers were immersed in aqueous solutions containing glutaraldehyde and glyoxal, and subsequently washed and dried. When the concentration of crosslinking agent was varied at room temperature over a constant time of 1 h, dry mechanical properties improved up to a point after which increasing concentrations resulted in degradation. Immersion time was also varied between 1 and 60 min at 25.8°C, and temperature was varied between 25.8 and 70.0°C, at fixed concentrations of both glyoxal and glutaraldehyde. It was demonstrated that mechanical improvements might be rendered at higher temperatures over lesser times. However, it was also shown that at higher temperatures, fiber mechanical properties would begin to diminish. Chitosan films were subjected to similar treatments in aqueous crosslinking solutions. Fourier transform infrared data (FTIR) on the films suggest that some interaction is occurring between the glutaraldehyde or glyoxal and the amine group on the chitosan backbone. © 1999 John Wiley & Sons, Inc.

A novel method of carrier frequency offset estimation for OFDM systems (2003)

The paper proposes a new CFO (carrier frequency-offset) estimation method for OFDM systems. This method uses scattered pilots to estimate both integer and fractional CFO, which are usually estimated by continual pilots. Since scattered pilots are usually used to estimate the CFR (channel frequency response), using them at the same time, to estimate frequency-offset does not bring about additional cost for the system. Thus, subchannels applied to transmit the continual pilots, are saved for useful data, which increases the spectral efficiency. Moreover, performances of estimating CFO by both scattered and continual pilots are compared and analyzed in both AWGN and multipath fading channels. Theoretical analysis and simulation results show that for both integer and fractional CFO estimation, the performance of the scattered pilots-based algorithm is as good as that of continual pilots-based algorithms or acceptable for practical application.
Modeling of polynucleotide translocation through protein pores and nanotubes (2002)

In an effort to understand recent experiments, we have performed Brownian dynamics simulations of polymer translocation through nanometer-scale protein pores under the influence of an external applied electric field. Multiple peaks in the translocation time distribution are observed in agreement with experiments. Under the same conditions, but replacing the protein pore with a rigid cylindrical tube of comparable size, only a single peak is observed in the translocation time distribution. These results directly show that the geometry of the protein pores is mainly responsible for multiple peaks observed in experiments. In the case of alpha-hemolysin channel, we find the vestibule, by confining many conformations of the translocating polymer, to be responsible for the second peak with longer translocation time.
Charge percolation in electroactive polymer films (1990)

A steady-state dual-electrode ring—disc technique which can be utilised to determine charge-transfer diffusion coefficients in electroactive and electronically conductive polymer films is described. The method has been applied to two different electroactive polymer films: a ruthenium containing redox polymer, [Ru(bpy)2(PVP)Cl]Cl, and the electronically conducting polymer polyaniline. Charge-transfer diffusion coefficients obtained for the redox polymer were of the order of 10–9 cm2 s–1. The latter value is at least three orders of magnitude greater than values obtained using cyclic voltammetry or chronoamperometry, and was presumed to correspond to electron-hopping diffusion, rather than couterion motion. In contrast, for the electronically conducting polymer little difference was observed between the diffusion coefficients obtained via the steady-state dual-electrode method (ca. 10–9 cm2 s–1) and values obtained using transient techniques (chronoamperometry, chronocoulometry) or complex impedance spectroscopy. This observation results in the implication that the counterion and electron diffusion coefficients are equal in magnitude. This proposal has also been confirmed from complex impedance spectroscopy. The shape of the steady-state current–potential response has been examined for both classes of polymers. In particular, the waveshape analysis for polyaniline films has shown that the redox transformation corresponding to the transition from an insulating to a conductive state, involves the transfer of two electrons, but does not conform to the simple Nernst equation. A modified Nernst equation is proposed which specifically considers interactions within the polymer layer. The departure from ideal conditions is quantified in terms of an interaction coefficient, σ, which has its origin in the Brown–Anson interaction theory. Representative cyclic voltammetric data for thin polyaniline layers are also examined, and confirm that the redox switching reaction must be viewed in the context of the Brown–Anson model.

On-line imitative interaction with a humanoid robot using a mirror neuron model (2004)

This study presents experiments on the imitative interactions between a small humanoid robot and a user. A mirror neuron model was implemented in a humanoid robot, based on the recurrent neural network model with parametric bias (RNNPB). The experiments showed that after the robot learns multiple cyclic movement patterns as embedded in the RNNPB, it can regenerate each pattern synchronously with the movements of a human who is demonstrating the corresponding movement pattern in front of the robot. On the other hand, the robot exhibits diverse interactive responses when the user demonstrates novel cyclic movement patterns. Those responses were analyzed and categorized. We propose that both the dynamics of coherence and incoherence between the robot and the user movements could enhance close interactions between them.
Electrolysis of Gaseous CO<sub>2</sub> to CO in a Flow Cell with a Bipolar Membrane (2017)

The conversion of CO2 to CO is demonstrated in an electrolyzer flow cell containing a bipolar membrane at current densities of 200 mA/cm2 with a Faradaic efficiency of 50%. Electrolysis was carried out by delivering gaseous CO2 at the cathode with a silver catalyst integrated in a carbon-based gas diffusion layer. Nonprecious nickel foam in a strongly alkaline electrolyte (1 M NaOH) was used to mediate the anode reaction. While a configuration where the anode and cathode were separated by only a bipolar membrane was found to be unfavorable for robust CO2 reduction, a modified configuration with a solid-supported aqueous layer inserted between the silver-based catalyst layer and the bipolar membrane enhanced the cathode selectivity for CO2 reduction to CO. We report higher current densities (200 mA/cm2) than previously reported for gas-phase CO2 to CO electrolysis and demonstrate the dependence of long-term stability on adequate hydration of the CO2 inlet stream.
The very unusual case of the IEC-robust IC with low HBM performance (2013)

In this work we will show for the first time the case of an IC robust to on-chip IEC 61000-4-2 ESD level events and, yet, consistently failing at low HBM levels (<;2KV). The causes for the miscorrelation will be investigated in detail. A more reliable indicator for HBM robustness will be indicated.

We present the ab initiostudy of the geometry, electronic structure, charged states, bonding, and vibrational modes of the recently synthesized fullerene-like $\mathrm{As}@{\mathrm{Ni}}_{12}@{\mathrm{As}}_{20}$ cluster which has icosahedral point symmetry [M. J. Moses, J. C. Fettinger, and B. W. Eichhorn, Science, 300, 778 (2003)]. We show that the molecule is vibrationally stable and will be electronically most stable in its $\ensuremath{-}3$ oxidation state in the condensed phase and in $\ensuremath{-}2$ state in the gas phase. We examine the bonding in this unusually structured molecule from charge transfer between atoms, infrared and Raman spectra, and charge-density isosurfaces.

Relative Biological Effectiveness Measurements Using Murine Lethality and Survival of Intestinal and Hematopoietic Stem Cells after Fermilab Neutrons Compared to JANUS Reactor Neutrons and 60 Co Gamma Rays (1984)

The relative biological effectiveness (RBE) of the 25-MeV (average energy) neutron beam at the Fermi National Accelerator Laboratory was measured using murine bone marrow (LD50/30) and gut (LD50/6) lethality and killing of hematopoietic colony forming units (CFU-S) or intestinal clonogenic cells (ICC). The reference radiation was 60Co gamma rays. The LD50/30 and LD50/6 for mice exposed to the Fermilab neutron beam were 6.6 and 8.7 Gy, respectively, intermediate between those of JANUS neutrons and 60Co gamma rays. The D0 values for CFU-S and ICC were 47 cGy and 1.05 Gy, respectively, also intermediate between the lowest values found for JANUS neutrons and the highest values found after 60Co gamma rays. The split-dose survival ratios for CFU-S at intervals of 1-6 hr between doses were essentially 1.0 for both neutron sources, while the corresponding split-dose survival ratio for 60Co gamma rays was consistantly above 1, reaching a maximum of 1.7 with a 1-hr interval between doses. The 3-hr split-dose survival ratios for ICC were 1.0 for JANUS neutrons, 1.85 for Fermilab neutrons, and 6.5 for 60Co gamma rays. The RBE estimates for LD50/30 were 1.5 and 2.3 for Fermilab and JANUS neutrons, respectively. Based on LD50/6, the RBEs were 1.9 (Fermilab) and 3.0 (JANUS). The RBEs for CFU-S D0 were 1.4 (Fermilab) and 1.9 (JANUS) and for jejunal microcolony D0 1.4 (Fermilab) and 2.8 (JANUS).
Light out-coupling enhancement of organic light-emitting devices with microlens array (2010)

Light out-coupling efficiency of organic light-emitting devices from high-index glass substrate into air is enhanced by attaching ordered microlens arrays, which are fabricated by a roll-to-roll mold transfer process. The dependence of microlens geometries on light extraction is analyzed experimentally and theoretically. An increase of 60% in the light out-coupling with an optimized elliptical microlens array is achieved over a conventional device without affecting the electroluminescent spectrum.

Quantification of Parapapillary Atrophy and Optic Disc (2011)

This software offers a means of quantifying the size of PPA on two-dimensional fundus images for the first time. The proposed algorithm is capable of detecting and quantifying PPA and OD regions repeatedly, with a mean accuracy of >93%, and could also provide additional information, such as the transverse and conjugate diameter of OD, which may be useful in eye-screening.
Tensile Properties of the Mandibular Condylar Cartilage (2008)

Mandibular condylar cartilage plays a crucial role in temporomandibular joint (TMJ) function, which includes facilitating articulation with the temporomandibular joint disc and reducing loads on the underlying bone. The cartilage experiences considerable tensile forces due to direct compression and shear. However, only scarce information is available about its tensile properties. The present study aims to quantify the biomechanical characteristics of the mandibular condylar cartilage to aid future three-dimensional finite element modeling and tissue engineering studies. Porcine condylar cartilage was tested under uniaxial tension in two directions, anteroposterior and mediolateral, with three regions per direction. Stress relaxation behavior was modeled using the Kelvin model and a second-order generalized Kelvin model, and collagen fiber orientation was determined by polarized light microscopy. The stress relaxation behavior of the tissue was biexponential in nature. The tissue exhibited greater stiffness in the anteroposterior direction than in the mediolateral direction as reflected by higher Young's (2.4 times), instantaneous (1.9 times), and relaxed (1.9 times) moduli. No significant differences were observed among the regional properties in either direction. The predominantly anteroposterior macroscopic fiber orientation in the fibrous zone of condylar cartilage correlated well with the biomechanical findings. The condylar cartilage appears to be less stiff and less anisotropic under tension than the anatomically and functionally related TMJ disc. The anisotropy of the condylar cartilage, as evidenced by tensile behavior and collagen fiber orientation, suggests that the shear environment of the TMJ exposes the condylar cartilage to predominantly but not exclusively anteroposterior loading.
Local colour image segmentation using singular value decomposition (2002)

A method was developed to segment images of complex scenes based on color content. The output of an interest operator provides focus toward regions within an image to be sampled for color content. Statistics for each data set sampled are used to cluster and estimate bounded regions within a transformed color space. Each region respectively represents a specific set. Mappings to transformed regions of color space are found using the singular value decomposition. The mean and variance of each color sample in the transformed color space represent characteristic features for their sampled set of points. Color segmentation is accomplished by establishing whether image pixels belong to any subset represented by the characteristic features. This work contributes a method to color-segment targets in images using local color information within an image stream.

Characterization and localization of the enzymatic deacylation of lipoteichoic acid in group A streptococci. (1979)

Protoplasts of a group A streptococcal strain were shown to contain enzymatic activity capable of converting lipoteichoic acid (LTA) to deacylated lipoteichoic acid (dLTA). The enzyme(s) appear to be located mainly in the membrane, although activity was also found in the cytoplasm. Determination of the sites of cleavage within the LTA molecule was approached by comparing the chemical composition of LTA and native dLTA. Native dLTA, as distinguished from chemically deacylated LTA, was isolated from buffer in which live streptococci had been resuspended and incubated. The chemical data suggest that the enzyme(s) was(were) lipolytic in nature; that is, the conversion of LTA to dLTA was the result of cleavage of the ester linkages between the fatty acids and the remainder of the LTA molecule.
Fluorescent and Lanthanide Labeling for Ligand Screens, Assays, and Imaging (2011)

The use of fluorescent (or luminescent) and metal contrast agents in high-throughput screens, in vitro assays, and molecular imaging procedures has rapidly expanded in recent years. Here we describe the development and utility of high-affinity ligands for cancer theranostics and other in vitro screening -studies. In this context, we also illustrate the syntheses and use of heteromultivalent ligands as targeted imaging agents.
Oxyphenbutazone—Anti-inflammatory Agent—in Prevention of Peritoneal Adhesions (1969)

Postoperative peritoneal adhesions are one of the important causes of intestinal obstruction. Coletti and Bossart<sup>1</sup>reported that in their series, intestinal adhesions were responsible for 90% of small bowel obstructions in the early postoperative period. Numerous agents have been studied experimentally and clinically with regard to their usefulness in preventing the formation of intraperitoneal adhesions, but none, as yet, has proved consistently useful. Considering formation of peritoneal adhesions as an inflammatory process,<sup>2</sup>an anti-inflammatory agent, oxyphenbutazone, has been used in this study to prevent it. <h3>Materials and Methods</h3> Forty rabbits were anesthetized with intravenously administered pentobarbital sodium. A laparotomy was carried out by a midline incision. The cecum and corresponding parietal peritoneum were scraped until the normal gloss was lost. The abdomen was closed in layers. The animals were studied in the following groups: <b>Group A.</b>—This group was subdivided into two. Group Al, the control group, consisted
