Cross-linked C60 Polymer Breaches the Quantum Gap (2004)

Sum rules predict the largest off-resonance electronic nonlinear susceptibility allowed by quantum mechanics. The range between (10-3/2 to 1) times the physical limit level has until now not been penetrated experimentally and has become known as the quantum gap. We report the first measured second hyperpolarizability to breach the quantum gap. Through cross-linking, the C60-polymer film reported used delocalized electrons from neighboring three-dimensional C60 molecules and realized significant red shift of its energy levels. An ultrafast second hyperpolarizability of 9.6 × 10-32 esu (55% of the physical limit) has been achieved.

Effects of CdTe growth conditions and techniques on the efficiency limiting defects and mechanisms in CdTe solar cells (1996)

CdTe solar cells were fabricated by depositing CdTe films on CdS/SnO2/glass substrates using close‐spaced sublimation (CSS) and metalorganic chemical vapor deposition (MOCVD). Te/Cd mole ratio was varied in the range of 0.02 to 6 in the MOCVD growth ambient in an attempt to vary the native defect concentration. Polycrystalline CdTe layers grown by MOCVD and CSS both showed average grain size of about 2 μm. However, the CdTe films grown by CSS were found to be less faceted and more dense compared to the CdTe grown by MOCVD. CdTe growth techniques and conditions had a significant impact on the electrical characteristics of the cells. The CdTe solar cells grown by MOCVD in the Te‐rich growth condition and by the CSS technique gave high cell efficiencies of 11.5% and 12.4%, respectively, compared to 6.6% efficient MOCVD cells grown in Cd‐rich conditions. This large difference in efficiency is explained on the basis of (a) XRD measurements which showed a higher degree of atomic interdiffusion at the CdS/CdTe interface in high performance devices, (b) Raman measurements which endorsed more uniform and preferred grain orientation by revealing a sharp CdTe TO mode in the high efficiency cells, and (c) carrier transport mechanism which switched from tunneling/interface recombination to depletion region recombination in the high efficiency cells. In this study, Cu/Au layers were evaporated on CdTe for the back contact. Lower efficiency of the Te‐rich MOCVD cells, compared to the CSS cells, was attributed to contact related additional loss mechanisms, such as Cd pile‐up near Cu/CdTe interface which can give rise to Cd‐vacancy defects in the bulk, and higher Cu concentration in the CdTe layer which can cause shunts in the device. Finally, SIMS measurements on the CdTe films of different crystallinity and grain size confirmed that grain boundaries are the main conduits for Cu migration into the CdTe film. Thus larger CdTe grain size or lower grain boundary area per unit volume can mitigate the adverse effect of Cu on the cell performance.
Changes in light‐scatter profile, membrane depolarization and calcium mobilization of neutrophils induced by G‐CSF in vivo (1994)

To extend our studies about phenotypical and functional alterations of G-CSF-induced neutrophils we have evaluated their light-scatter profile, mobilization of intracellular calcium ([Ca2+]i) and membrane depolarization after stimulation. A significant increase in the forward scatter signals could be demonstrated in such neutrophils from patients with neutropenias of various origin and from healthy test subjects. This increase began 4 h and returned to normal 96 h after G-CSF injection in the latter group. We found an impairment of [Ca2+]i mobilization in neutrophils from patients with glycogen storage disease type IB after stimulation of these cells with fMLP. It was even more pronounced than in severe congenital neutropenia (SCN). However, [Ca2+]i fluxes were normal when ionomycin was used. Neutrophils from patients with cyclic neutropenia (cyNP) and chemotherapy-induced neutropenia (chNP) mobilized [Ca2+]i similar to those from healthy donors. Furthermore, we found a decreased percentage of neutrophils depolarizing after stimulation with fMLP and PMA in patients with SCN, whereas membrane depolarization was normal in patients with chNP and cyNP. All the alterations found here are suggested to be caused by a partial immaturity of the neutrophils, although in vivo activation and a direct effect of G-CSF on myeloid precursors might be involved.
Repulsion–attraction switching of nematic colloids formed by liquid crystal dispersions of polygonal prisms (2017)

Self-assembly of colloidal particles due to elastic interactions in nematic liquid crystals promises tunable composite materials and can be guided by exploiting surface functionalization, geometric shape and topology, though these means of controlling self-assembly remain limited. Here, we realize low-symmetry achiral and chiral elastic colloids in the nematic liquid crystals using colloidal polygonal concave and convex prisms. We show that the controlled pinning of disclinations at the prism edges alters the symmetry of director distortions around the prisms and their orientation with respect to the far-field director. The controlled localization of the disclinations at the prism's edges significantly influences the anisotropy of the diffusion properties of prisms dispersed in liquid crystals and allows one to modify their self-assembly. We show that elastic interactions between polygonal prisms can be switched between repulsive and attractive just by controlled re-pinning the disclinations at different edges using laser tweezers. Our findings demonstrate that elastic interactions between colloidal particles dispersed in nematic liquid crystals are sensitive to the topologically equivalent but geometrically rich controlled configurations of the particle-induced defects.
Novel transition between different configurations of planar transmission lines (2002)

New designs of coplanar waveguide (CPW)-microstrip, CPW-stripline, conductor backed CPW (CBCPW)-microstrip, and CBCPW-stripline transitions are presented. Simulation using the high frequency structures simulator (HFSS) shows that the return loss of the CPW-microstrip transition is less than -25 dB up to 11 GHz. Similarly is the CPW-stripline transition. In the case of two back to back CBCPW-stripline transitions, the return loss is less than -22 dB up to 9 GHz. Experimentally, the S/sub 11/ of two back to back CBCPW-microstrip transitions on an alumina substrate is less than -15 dB up to 25 GHz.
Pathological studies on the liver with extrahepatic portal obstruction. (1986)

We report pathological features and histometrical analyses of the portal tracts in the liver with extrahepatic portal obstruction in adult. Cavernous transformation was frequently observed in medium-size portal tracts, usually associated with narrowing of the portal vein. The histometrical study showed dilatation of the hepatic artery in extrahepatic portal obstruction, compared with idiopathic portal hypertension and the normal control. It is suggested that the dilatation of the hepatic artery in the medium-size portal tracts may reflect an increased arterial blood flow which serves to compensate for the insufficient portal circulation due to the sclerosed and narrowed portal vein.

Effect of ultrasound therapy on the repair of Achilles tendon injuries in rats. (1991)

The purpose was to determine the effects of selected regimens of ultrasound therapy on the rates of repair of injured Achilles tendons of rats. Specific dependent variables examined were tendon breaking strength and rate of collagen formation. A puncture technique was used to induce injuries to both Achilles tendons of rats. Continuous ultrasound was administered to the left tendon for 4 min per treatment session at an intensity of 1.5 W.cm-2. Rats were sacrificed 2, 5, 9, 15, and 21 d following injury for measurement of tendon breaking strength and 3 and 5 d postinjury for analysis of collagen synthesis. Breaking strength was defined as the minimum force required to completely rupture the tendon. Collagen synthesis was indicated by the conversion of labeled proline to hydroxyproline. The breaking strengths of the treated tendons were significantly greater than strengths of the untreated tendons 5, 9, 15, and 21 d postinjury. Collagen synthesis was increased in the treated tendons compared with the untreated tendons 5 d postinjury. The results indicate that ultrasound treatment increases the rate of repair of injured Achilles tendons of rats. The results are also consistent with an association between increased collagen synthesis and greater breaking strength during tendon repair.
Effect of alloy surface composition on release of elements from dental casting alloys (1996)

The release of elements from dental casting alloys is a continuing concern because of the potentially harmful biological effects the elements may have on local tissues. The surfaces of the alloys appear to be most important in controlling the release of these elements. In the current study, the surfaces of high-, reduced-, and no-gold dental alloys were analysed by X-ray photoelectron spectroscopy before and after they were exposed to a biological medium for up to 96 h. The goal was to relate the release of elements from these alloys to their surface composition, and to determine the depth of the effect of the medium. The depth of the effect of the exposure was determined by argon milling of the alloy surface after exposure to the medium. Elements that were released into the medium were measured by means of atomic absorption spectroscopy. The release of elements from alloys was greater when the atomic ratio of noble to non-noble elements at the surface was less than 1. The depth of the effect of the medium varied with the alloy, but was always less than 100 A. The surface composition was significantly different from layers only 5 A below. It was concluded that the surface concentration of noble elements is important in controlling the release of non-noble elements from these alloys, and the surface composition appeared to be only one or two atomic layers thick. Of the three types of alloys, the high-gold alloy appeared to develop the most stable surface composition which released the lowest levels of elements.
Identification of genomic differences between Campylobacter jejuni subsp. jejuni and C. jejuni subsp. doylei at the nap locus leads to the development of a C. jejuni subspeciation multiplex PCR method (2007)

The nap multiplex PCR primer sets are robust and give a 100% discrimination of C. jejuni subspecies. The ability to rapidly subspeciate C. jejuni as well as speciate thermophilic Campylobacter species, most of which are pathogenic in humans, in a single amplification will be of value to clinical laboratories in strain identification and the determination of the environmental source of campylobacterioses caused by Cjd. Finally, the sequences of the Cjd napA and napB loci suggest that Cjd strains arose from a common ancestor, providing clues as to the potential evolutionary origin of Cjd.
A solid-mounted resonator-oscillator-based 4.596 GHz frequency synthesis (2011)

This paper describes a 4.596 GHz frequency synthesis based on a 2.1 GHz solid mounted resonator (SMR) voltage-controlled oscillator (VCO). The SMR oscillator presents a chip size lower than 2 mm(2), a power consumption of 18.2 mW, and exhibits a phase noise of -89 dBc/Hz and -131 dBc/Hz at 2 kHz and 100 kHz offset frequencies, respectively. The VCO temperature-frequency dependence is measured to be -14 ppm∕°C over a range of -20°C to 60°C. From this source, a low noise frequency synthesizer is developed to generate a 4.596 GHz signal (half of the Cs atom hyperfine transition frequency) with a phase noise of -81 dBc/Hz and -120 dBc/Hz at 2 kHz and 100 kHz from the carrier. The frequency synthesis output is used as a local oscillator in a Cs vapor microcell-based compact atomic clock. Preliminary results are reported and discussed. To the authors knowledge, this is the first development of a SMR-oscillator-based frequency synthesizer for miniature atomic clocks applications.
Observation of filamentation in As2S3 (2001)

We report on the observation of permanent filamentation in a slab waveguide made of As2S3, a photosensitive material. The process occurs through the self-writing of a channel waveguide. The presence of multiple filaments seems to be related to the quality of the wavefront.
An approach from the sociology of the body to social movements (2013)

<p class="MsoNormal" style="text-align: justify;">The present article has as aim articulate two somewhat separate perspectives of the sociological current debate:The sociology of the social movements and the sociology of the body. In this respect, we look to problematized three things. First, why the relevance of the category body, especially the nude, as form and / or resource in the protests. Second, from the thought of Foucault how the social thing interferes in the body, in phenomena as personal as sexuality or family. Finally, from the tensions outlined in section two, we discuss how this gives rise to movements that have claims related to the body, and what theory of social movements is the best to explain it.
An Estimation Method of Possible Mode Confusion in Human Work with Automated Control Systems (2006)

This paper proposes a new method to estimate possible confusions human users may make on the current mode of an automated control system that they are required to work with. The proposed method takes its stand on a philosophy that the users depend on the system's response behaviors to some extent as valuable cues to sense its state, and thus that different modes in which the system exhibits the same response behaviors to a particular user operation are hard to be distinguished by them. All the modes are encoded into vector forms from the perspective of their "input-output relations," and then the distances among the vectors are utilized as indexes to estimate the likelihoods of mode confusions. The idea is validated through the experiments using a driving simulator with Adaptive Cruise Control (ACC) implemented, in which drivers are queried as to the current mode of the ACC system to collect the probability distributions of mode confusion to be compared with what has been estimated. In addition, it is also examined whether purposefully designed input-output relations can contribute to the improvements of the drivers' awareness of modes.
Optical fiber units with ferroelectric liquid crystals for optical computing (1991)

Several simple arrangements of optical fibers joined with fibers have been examined. Sufficient coupling efficiency in the arrangements examined has not been achieved. The maximum SNR in the guidelines investigated was 10:
A homozygous MRPL24 mutation causes a complex movement disorder and affects the mitoribosome assembly (2020)

Mitochondrial ribosomal protein large 24 (MRPL24) is 1 of the 82 protein components of mitochondrial ribosomes, playing an essential role in the mitochondrial translation process. We report here on a baby girl with cerebellar atrophy, choreoathetosis of limbs and face, intellectual disability and a combined defect of complexes I and IV in muscle biopsy, caused by a homozygous missense mutation identified in MRPL24. The variant predicts a Leu91Pro substitution at an evolutionarily conserved site. Using human mutant cells and the zebrafish model, we demonstrated the pathological role of the identified variant. In fact, in fibroblasts we observed a significant reduction of MRPL24 protein and of mitochondrial respiratory chain complex I and IV subunits, as well a markedly reduced synthesis of the mtDNA-encoded peptides. In zebrafish we demonstrated that the orthologue gene is expressed in metabolically active tissues, and that gene knockdown induced locomotion impairment, structural defects and low ATP production. The motor phenotype was complemented by human WT but not mutant cRNA. Moreover, sucrose density gradient fractionation showed perturbed assembly of large subunit mitoribosomal proteins, suggesting that the mutation leads to a conformational change in MRPL24, which is expected to cause an aberrant interaction of the protein with other components of the 39S mitoribosomal subunit.
Uric acid prevents traumatic cell death and neuronal dysfunction in organotypic hippocampal slice cultures (2010)

The efficacy of uric acid (UA) to prevent cell death and preserve electrophysiological function after traumatic brain injury was tested in an in vitro model. UA significantly reduced post-traumatic cell death and attenuated changes in electrophysiological measures. UA may be a promising novel therapeutic for traumatic brain injury which warrants further study in animal models.
An Input Output HMM Architecture (1994)

We introduce a recurrent architecture having a modular structure and we formulate a training procedure based on the EM algorithm. The resulting model has similarities to hidden Markov models, but supports recurrent networks processing style and allows to exploit the supervised learning paradigm while using maximum likelihood estimation. 1 INTRODUCTION Learning problems involving sequentially structured data cannot be effectively dealt with static models such as feedforward networks. Recurrent networks allow to model complex dynamical systems and can store and retrieve contextual information in a flexible way. Up until the present time, research efforts of supervised learning for recurrent networks have almost exclusively focused on error minimization by gradient descent methods. Although effective for learning short term memories, practical difficulties have been reported in training recurrent neural networks to perform tasks in which the temporal contingencies present in the input/ou...
Recomputing by operand exchanging: a time-redundancy approach for fault-tolerant neural networks (2002)

The use of neural networks in mission-critical applications requires concurrent error detection and correction at architectural level to provide high consistency and reliability of system's outputs. Time redundancy allows for fault tolerance in digital realizations with low circuit complexity increase. In this paper, we propose the use of REcomputation with eXchanged Operands-an approach based on operands' rotation-to introduce concurrent error detection and correction, when timing constraints are not particularly strict. Different architectural approaches for neural design are considered to match the implementation constraints and to show the versatility of the proposed solutions.
Subcloning and Nucleotide Sequencing of an ARS Site ofCandida maltosaWhich Also Functions inSaccharomyces cerevisiae (1987)

A DNA region exhibiting ARS activity in Candida maltosa was subcloned from an isolated 3.8 kb DNA fragment and designated as the TRA region previously [M. Takagi et al., J. Bacteriol., 167, 551 (1986)], which replicates autonomously not only in C. maltosa but also in Saccharomyces cerevisiae. It was found that a DNA fragment of about 200 bp (designated as fragment 2) exhibited ARS activity in both yeasts, and nucleotide sequence analysis of this fragment revealed that it contained five 11 bp-sequences which are homologous to the consensus sequence of ARS sites of S. cerevisiae [J. R. Broach et al., Cold Spring Harbor Symp. Quant. Biol., 47, 1167 (1982)] (9 among 11 bp being identical in each). Plasmids constructed using fragment 2 (pTRA2 and pTRA12) will be useful as cloning vectors, although they showed lower transforming frequencies and lower stabilities in C. maltosa than plasmids containing the TRA region (pTRA1 and pTRA11).
