Data associated with publication "Contributions to Composite Conductivity and Seebeck Coefficient in Commercial Bi2Te3 – Conjugated Polymer Composites" (2019)

We demonstrated the use of the as-received conjugated polymer P3HT (poly (3-hexylthiophene-2,5 diyl) doped with F4TCNQ (2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane) as a matrix for forming a composite with as-received, commercially available p-type Bi2Te3 powder. The optimized formulation exhibits a power factor of up to 5.3 uW K-2 m-1, about nine times higher than the highest power factor we achieved from mixtures of only P3HT and F4TCNQ. The Bi2Te3 was responsible for increases in both Seebeck coefficient and electrical conductivity. P3HT, with higher hole mobility, was superior to PQT12 (poly(bisdodecylquaterthiophene), and F4TCNQ was at least as good as FeCl3, for matrix and dopant, respectively, for this purpose. The power factor obtained is about 40% of that reportedly obtained from synthesized Bi2Te3 nanowires in FeCl3-doped P3HT. We calculated the expected contributions of bulk Bi2Te3 to the composite conductivity and then examined the resistance caused by interfaces on four different size distributions of Bi2Te3 particles, as well as a solid macroscopic ingot. A nonlinear I-V relationship was found for the doped P3HT-ingot bilayer. While our doped conjugated polymer system made only from commercial-grade components was shown to support the extraction of thermoelectric performance by a commonly used inorganic semiconductor, our results also suggest that an advantage of the smallest Bi2Te3 domains, including nanowires, may arise from their having less interfacial resistance than larger Bi2Te3 particles and pieces.

Three-Phase Bidirectional Buck-Boost Current DC-Link EV Battery Charger Featuring a Wide Output Voltage Range of 200 to 1000V (2020)

High power EV chargers connected to an AC power distribution bus are employing a three-phase AC/DC Power Factor Correction (PFC) front-end and a series-connected isolated DC/DC converter to efficiently regulate the traction battery voltage and supply the required charging current. In this paper, the component stresses and the design optimization of a novel two-stage three-phase bidirectional buck-boost current DC-link PFC rectifier system, realized solely with SiC power MOSFETs and conveniently requiring only a single magnetic component, are introduced. This topology offers a high efficiency in a wide operating range thanks to the synergetic operation of its two stages, the three-phase buck-type current source rectifier stage and the subsequent three-level boost-type DC/DC-stage, which makes it suitable for on-board as well as off-board charger applications. The calculated voltage and current component stresses of the proposed converter system, considering an output voltage range of 200 to 1000 V and up to 10 kW of output power, help to identify its operating boundaries, maximizing the utilization of the power semiconductors and of the DC-link inductor. The optimum values of the circuit parameters are selected after evaluating the converter average efficiency η and volumetric power density p in the Pareto performance space and analyzing its design space diversity, focusing on the semiconductor losses and on the characteristics of the inductor. Considering typical EV battery charging profiles, i.e. taking both full-load and part-load operation into account, a power converter realization featuring η = 98.5 % and p = 13.9 kW/dm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> is achieved.
[Peroral vaccine therapy in dermatology]. (1995)

In a group of 691 patients with different dermatoses the therapeutic effect of two forms of lyophilized vaccines administered orally according to a desensitization (drops) and immunization (tablets) plan. Their effect was as a rule marked already during the third week of treatment. During the final evaluation no signs of the disease were present or great improvement was recorded in 89-100% of the patients suffering from acne, chronic staphylococcal pyoderma or microbial eczema and 62% (drops) or 65% (tablets) of patients with atopic eczema. During treatment the authors did not observe with rare exceptions of focal reactions any undesirable effects. No significant differences were found between the two forms of the drugs as regards therapeutic effects. Contrary to antibiotics, which can cause remission of dermatosis, while early relapses cannot be prevented, oral vaccine treatment leads to long-term (extending over several years) favourable effects on the course of the disease. The immunization pattern used in tablet form vaccines is simpler, packing and storage is simpler, dosage is more accurate and more convenient for the patient.
Experimental Demonstration of a Resonator-Induced Phase Gate in a Multiqubit Circuit-QED System (2016)

The resonator-induced phase (RIP) gate is an all-microwave multiqubit entangling gate that allows a high degree of flexibility in qubit frequencies, making it attractive for quantum operations in large-scale architectures. We experimentally realize the RIP gate with four superconducting qubits in a three-dimensional circuit-QED architecture, demonstrating high-fidelity controlled-z (cz) gates between all possible pairs of qubits from two different 4-qubit devices in pair subspaces. These qubits are arranged within a wide range of frequency detunings, up to as large as 1.8 GHz. We further show a dynamical multiqubit refocusing scheme in order to isolate out 2-qubit interactions, and combine them to generate a 4-qubit Greenberger-Horne-Zeilinger state.

Chemical Properties in CAD-deficient Pine and Their Effect on Pulping (2005)

Incremental cores of 200 selected trees were collected from a 10 years old open pollinated family trail growing under two nutrition treatment in Scotland County, North Carolina. We analyzed wood density, chemical and pulping properties. Analysis of the samples with NIR allows estimation of lignin, α-cellulose and hemicellulose contents in each annual ring. Analysis of selected samples by quantitative {13}C NMR showed almost no differences between cad-n1 and wild-type MWL isolated from juvenile wood. However, there were some differences between cad-n1 and wild MWL isolated from mature wood. A micro technique was eveloped to allow isolation and comprehensive analysis of lignin using the amount of wood that can be obtained from each annual ring in an incremental core. Analysis of a fraction of crude MWL containing concentrated LC fragments allows detection and quantification of phenyl-glycoside bonds. Ester bonds between uronic acids and γ−position of lignin were detected in contrast to benzyl ester linkages. Heterozygote did not show any significant differences in kraft pulping as compared to pulping of the wild type. {13}C NMR studies showed that the structure of the kraft lignin isolated from pulping of CAD-deficient pine is rather similar to that of the control.
Concentrations of energy substrates in oviductal fluid and blood plasma of pigs during the peri-ovulatory period (1992)

Summary. Large White gilts, 9 to 18 months old, that had exhibited at least two natural oestrous cycles were divided into three groups (phases): unmated pre-ovulatory, unmated post-ovulatory and mated post-ovulatory (n = 16, 20 and 18). Oviductal luminal fluid samples were collected under anaesthesia by micropipette from the ampulla and ampullary–isthmic junction and analysed by an ultramicrofluorometric technique. Glucose concentrations (mmol l−1, means combining regions; mean ± sem) were significantly higher in blood plasma than in oviductal fluid (4·56 ± 0·20 versus 0·59 ± 0·16; P &amp;lt; 0·0001; n = 27), whereas lactate was higher in the oviduct (5·71 ± 0·53 versus 2·48 0·24; P &amp;lt; 0·0001; n = 27). No significant differences were found between the ampulla and the ampullary–isthmic junction. However, the concentration of glucose was significantly higher (P &amp;lt; 0·05) in the ampulla of the pre-ovulatory group (0·97 ± 0·20; n = 13) compared with the mated group (0·25 ± 0·05; n = 14) and its concentration in the ampullary–isthmic junction in the pre-ovulatory group (1·65 ± 0·63; n = 13) was significantly greater (P &amp;lt; 0·05) than in the post-ovulatory (0·43 ± 0·11; n = 11) or mated groups (0·17 ± 0·02; n = 14). Lactate in the ampulla of mated animals was higher than in the pre-ovulatory group (6·83 ± 0·70 versus 3·86 ± 0·38; P &amp;lt; 0·05; n = 15 and 13), but neither was significantly different from the post-ovulatory group. Furthermore, no change was seen at the ampullary–isthmic junction in lactate concentration with phase. Pyruvate concentrations showed no differences with phase, region or with plasma (oviduct 0·21 ± 0·02; plasma 0·14 ± 0·01; n = 27 and 26). Glucose concentration within the oviduct decreased at a time when gametes or embryos, with their liberated cumulus cells, were present. Consequently it is evident that the microenvironment of the gametes and embryos is changing and, in the light of these measurements, the composition of the media used for in vitro culture experiments may require modification to reflect the physiological levels more closely.

Catheter-based polarization sensitive optical coherence tomography with a single input polarization state (2023)

Despite promise in early pilot studies, clinical translation of intravascular PS-OCT has been limited by the complexity of incorporating polarization modulation. We present a signal processing pipeline which uses maximum-likelihood estimation to reconstruct the polarization properties of tissue measured with a single input polarization state (SIPS-OCT), enabling polarization-sensitivity with existing intravascular OCT devices. SIPS-OCT estimates both the depth resolved birefringence and optic axis orientation, with excellent qualitative and quantitative comparisons to conventional dual-input state PS-OCT. These results present an encouraging step towards removing barriers to PS-OCT adoption by enabling polarization-sensitivity in existing intravascular OCT systems.
Resection frequency map after awake resective surgery for non-lesional neocortical epilepsy involving eloquent areas (2011)

Awake resective surgery with intraoperative brain mapping is an effective and safe treatment option for non-lesional epilepsy involving eloquent areas. The resection frequency map can show the resected area of a group as well as individuals and provide an objective measure of neurological risk.
The tandem zinc finger RNA binding domain of members of the tristetraprolin protein family (2019)

Tristetraprolin (TTP), the prototype member of the protein family of the same name, was originally discovered as the product of a rapidly inducible gene in mouse cells. Development of a knockout (KO) mouse established that absence of the protein led to a severe inflammatory syndrome, due in part to elevated levels of tumor necrosis factor (TNF). TTP was found to bind directly and with high affinity to specific AU-rich sequences in the 3'-untranslated region of the TNF mRNA. This initial binding led to promotion of TNF mRNA decay and inhibition of its translation. Many additional TTP target mRNAs have since been identified, some of which are cytokines and chemokines involved in the inflammatory response. There are three other proteins in the mouse with similar activities and domain structures, but whose KO phenotypes are remarkably different. Moreover, proteins with similar domain structures and activities have been found throughout eukaryotes, demonstrating that this protein family arose from an ancient ancestor. The defining characteristic of this protein family is the tandem zinc finger (TZF) domain, a 64 amino acid sequence with many conserved residues that is responsible for the direct RNA binding. We discuss here many aspects of this protein domain that have been elucidated since the original discovery of TTP, including its sequence conservation throughout eukarya; its apparent continued evolution in some lineages; its functional dependence on many key conserved residues; its "interchangeability" among evolutionarily distant species; and the evidence that RNA binding is required for the physiological functions of the proteins.

Abstract 4623: Meta-analysis of transcriptomic profiles identifies prognostic model for pancreatic ductal adenocarcinoma patients (2018)

Abstract Purpose The main objective was to develop a robust molecular predictor model with high prognostic value across multiple independent cohorts of pancreatic ductal adenocarcinoma (PDAC) patients using a novel meta-analysis framework. The median 5-year overall survival (OS) of PDAC patient is &amp;lt;8%. Only 10-20% of patients are eligible for surgery, and of these, more than half will die within a year of surgery. The identification of a biologically relevant molecular predictor model is urgently needed to define strategies that may help patient selection at high risk of early death to inform treatment decisions. Methods We developed the Pancreatic Cancer Overall Survival Predictor (PCOSP), a new prognostic model built from a unique set 89 PDAC patients whose gene expressions have been profiled using both microarray and sequencing platforms. We used the recent binary gene pair method to create gene expression barcodes robust to biases arising from heterogeneous profiling platforms and batch effects. Leveraging the largest compendium of PDAC transcriptomic datasets to date, including 1,198 patients, we show that PCOSP is a robust single-sample predictor of early death (≤1 yr) after surgery in a subset of 823 validation samples with available trancriptomics and survival data. Results The PCOSP model was strongly and significantly prognostic overall with a meta-estimate of the area under the ROC curve of 0.70 (P=1.9e-18) and hazard ratio of 1.95 (P=2.6e-16) for binary and survival predictions, respectively. The prognostic value of PCOSP was independent of clinicopathological parameters and molecular subtypes. The PCOSP model includes 2,619 gene pairs, with 1,070 unique genes. Over-representation analysis of these genes unveiled pathways associated with Hedgehog signalling, epithelial mesenchymal transition (EMT) and extracellular matrix (ECM) signalling at FDR&amp;lt;0.05. Conclusions This study reports a PCOSP model to predict post-operative OS independently of clinicopathological features. This may assist clinicians in making decisions that would ultimately improve the OS and facilitate decisions concerning a surgery-first versus a neoadjuvant approach. The functional analysis of the PCOSP genes may give further insight to tumor biology of short-term survival PDAC patients.

Finite-SNR analysis for partial relaying cooperation with channel coding and opportunistic relay selection (2017)

This work studies the performance of a cooperative network which consists of two channel-coded sources, multiple relays, and one destination. To achieve high spectral efficiency, we assume that a single time slot is dedicated to relaying. Conventional network-coded-based cooperation (NCC) selects the best relay which uses network coding to serve the two sources simultaneously. The bit error rate (BER) performance of NCC with channel coding, however, is still unknown. In this paper, we firstly study the BER of NCC via a closed-form expression and analytically show that NCC only achieves diversity of order two regardless of the number of available relays and the channel code. Secondly, we propose a novel partial relaying-based cooperation (PARC) scheme to improve the system diversity in the finite signal-to-noise ratio (SNR) regime. In particular, closed-form expressions for the system BER and diversity order of PARC are derived as a function of the operating SNR value and the minimum distance of the channel code. We analytically show that the proposed PARC achieves full (instantaneous) diversity order in the finite SNR regime, given that an appropriate channel code is used. Finally, numerical results verify our analysis and demonstrate a large SNR gain of PARC over NCC in the SNR region of interest.
Simultaneous diffraction of two finite waves at a nonuniform mixed dynamic transmission grating (1990)

Diffraction of two light waves at a planar, finite transmission mixed grating is considered, utilizing the two-dimensional coupled-wave theory. Diffraction characteristics of two important cases, incident beams with uniform or Gaussian profiles, are presented. The dependence of the diffraction properties (beam profiles and diffraction efficiency) on the normalized parameter grating strength γ and on the phase shift ϕ of the grating with respect to the interference pattern of the readout waves in the case of pure phase gratings and absorption gratings is shown. The results are compared with the complete solution of the one-dimensional theory.
Gas diffusion electrode for oxygen reduction loaded with lanthanum-based perovskite-type oxides. (1986)

酸素還元用炭素電極触媒としてLa0.6Sr0.4Fe0.6M0.4O3(M=Mn,Co)型の多成分系ペロブスカイト型酸化物が非常に有効であることがわかった。とくにLa0.6Sr0.4Fe0.6M0.4O3を40wt%添加したときの電極性能は非常に高く酸素還元に対する電流密度は-125mV(vs.Hg/HgO)(0.8Vvs.RHE)で1600mA/cm2もの値が得られた。この値はカーボン単独の場合の15倍であった。これらの多成分系複合酸化物は酸素の四電子還元(O2+2H2O+4e-→4OH-)に対する活性が高いだけでなく, 同時に過酸化水素の分解活性(HO2-→1/2O2+OH-)も高いことがわかった。電極の短期連続試験の結果,300mA/cm2の電流密度においてカーボン単独の場合は12時間後には劣化が生じ30蒔間後には破壊してしまったのに対し, La0.6Sr0.4Fe0.6M0.4O3を添加した電極では50時間安定に作動することがわかった。
Intense Radioisotope Sources for Spin Polarized Positron Beams (2005)

Design, transport performance study and engineering of a 11 Tb/s US mesh metro network (2002)

A new top-down simulation methodology for successfully enabling transparent optical networks in the metro environment is presented. A 11 Tb/s ILEC network was engineered based on projected traffic demands for a typical medium size US metropolitan area. The approach combines traffic modeling, network dimensioning, and transport layer performance modeling. The latter is further composed of three main simulation steps: efficient wavelength-domain simulations for network crosstalk analysis, time-domain simulation for determining Q-penalties for pulse propagation effects and finally a Q-budgeting approach that combines the above results for flexible network design and engineering. As a result metro players like ILECs or CLECs can effectively and quickly engineer transparent networks in the metro environment using simulation methodologies like the above. Details on the actual traffic and transport layer models used as well as experimental validation results for the models will be presented in more detail at the conference.
Investigation of Basal Plane Dislocation Reduction/Elimination by Molten KOH-NaOH Eutectic Etching Method (2012)

An optimized molten KOH-NaOH eutectic etching method is developed to reveal defects in highly n-doped SiC substrates and to pre-treat the substrate prior to epitaxial growth. Different from the conventional KOH etching method, by way of eutectic method, the basal plane dislocation (BPD) conversion in the subsequent epitaxial growth is independent of the etch pit size pre-generated on the substrate. Even with a short period (~3 minutes) of pretreatment which does not generate any visible etch pits or degradation of surface morphology on the substrate, an epilayer with low BPD density -2 is still achieved. This simple and non-destructive method shows high potential to be practically employed as one of the basic pretreatment steps to the substrates in SiC epitaxial growth in order to achieve very low or free BPD density.
Erratum: Investigation of the fatty acid transporter-encoding genes SLC27A3 and SLC27A4 in autism (2016)

The solute carrier 27A ( SLC27A ) gene family encodes fatty acid transport proteins (FATPs) and includes 6 members. During fetal and postnatal periods of development, the growing brain requires a reliable supply of fatty acids. Because autism spectrum disorders (ASD) are now recognized as disorders caused by impaired early brain development, it is possible that functional abnormalities of SLC27A genes may contribute to the pathogenesis of ASD. Here, we confirmed the expression of SLC27A3 and SLC27A4 in human neural stem cells derived from human induced pluripotent stem cells, which suggested their involvement in the developmental stage of the central nervous system. Additionally, we resequenced the SLC27A3 and SLC27A4 genes using 267 ASD patient and 1140 control samples and detected 47 (44 novel and 29 nonsynonymous) and 30 (17 novel and 14 nonsynonymous) variants for the SLC27A3 and SLC27A4 , respectively, revealing that they are highly polymorphic with multiple rare variants. The SLC27A4 Ser209 allele was more frequently represented in ASD samples. Furthermore, we showed that a SLC27A4 Ser209 mutant resulted in significantly higher fluorescently-labeled fatty acid uptake into bEnd3 cells, a mouse brain capillary-derived endothelial cell line, compared with SLC27A4 Gly209, suggesting that the functional change may contribute to ASD pathophysiology.
