Multidimensional 19F NMR Analyses of Terpolymers from Vinylidene Fluoride (VDF)–Hexafluoropropylene (HFP)–Tetrafluoroethylene (TFE) (2015)

The use of multidimensional NMR methods for the characterization of polymer microstructure has been applied to terpolymers from vinylidene fluoride (VDF), hexafluoropropylene (HFP), and tetrafluoroethylene (TFE). By assembling the atomic connectivity information obtained from different multidimensional NMR experiments, selective 19F–19F COSY (correlation spectroscopy), 19F–19F gradient double-quantum COSY, and 19F–13C gradient heteronuclear single-quantum coherence (gHSQC), among others, the detailed monomer sequence arrangements in the terpolymer were obtained. Obtaining the resonance assignments of the terpolymer was greatly aided by the extrapolation of known resonance assignments from PVDF homopolymer, poly(VDF-co-HFP) copolymer, and poly(VDF-co-TFE) copolymer. A tabulated comparison of the microstructure assignment of resonances from PVDF homopolymer as well as poly(VDF-co-HFP) and poly(VDF-co-TFE) copolymers and the terpolymer is provided. Detailed comparisons of 19F spectra from 470 and 658.4 MHz spectrometers, revealing the AB patterns present in this terpolymer, are presented and discussed in this paper. The compositions of the comonomers in the terpolymers were calculated with different methods, all of which gave similar values. The percentages of VDF and HFP monomer inversions in the terpolymers were also calculated from the assigned NMR resonances.
Experimental evaluation of a novel CdZnTe flat-panel x-ray detector for digital radiography and fluoroscopy (2001)

We made a prototype flat-panel X-ray detector with a polycrystalline CdZnTe film, and evaluated its imaging performance with respect to leakage current, X-ray sensitivity, MTF, DQE and image lag. The detector incorporates a novel hybrid technique in which zinc-doped CdTe is pre-deposited onto a ceramic substrate and then connected to a TFT circuit substrate. We carefully selected the material for the sensor substrate in order to avoid both incident x-ray attenuation in the substrate and micro-cracks in CdZnTe film. The film thickness was approximately 300 micrometers . The imaging area is composed of 512 X 384 pixels, with a pixel pitch of 150 micrometers .
Image Analysis on Tumor Stroma Extending around the Central Fibrotic Foci of Peripheral Pulmonary Adenocarcinoma. (1992)

末梢型肺腺癌で中心部線維化巣 (central fibrosis: CF) を形成するType 2腺癌の, CF周囲肺進展部での腫瘍間質内弾性線維 (elastic fiber: EF) を画像解析した.検索症例のX線経過は, 約半年単位の短期経過で, 腫瘤径の増大が明瞭であった.このX線上の陰影増大経過は, 組織でのCF周囲進展部の広さに合致していた.CF周囲進展部のEF網は, たわみの乏しいThick EFが薄い肺胞壁をskipして構成されていて, 正常肺胞構築との類似性が強い.単位肺胞壁長あたりのEF量, EF長は正常肺胞でのそれより増大していたが軽度で, 2倍程度までに留まっていた.この結果, CF周囲腫瘍進展部肺胞壁は, Type 1腺癌でみられた強い肺胞壁の肥厚, 収縮等はみられず, 正常肺胞壁がそのままに腫瘍間質を形成していると考えられた.
Designed Nanocage Displaying Ligand-Specific Peptide Bunches for High Affinity and Biological Activity (2013)

Protein-cage nanoparticles are promising multifunctional platforms for targeted delivery of imaging and therapeutic agents owing to their biocompatibility, biodegradability, and low toxicity. The major advantage of protein-cage nanoparticles is the ability to decorate their surfaces with multiple functionalities through genetic and chemical modification to achieve desired properties for therapeutic and/or diagnostic purposes. Specific peptides identified by phage display can be genetically fused onto the surface of cage proteins to promote the association of nanoparticles with a particular cell type or tissue. Upon symmetrical assembly of the cage, peptides are clustered on the surface of the cage protein in bunches. The resulting PBNC (peptide bunches on nanocage) offers the potential of synergistically increasing the avidity of the peptide ligands, thereby enhancing their blocking ability for therapeutic purposes. Here, we demonstrated a proof-of-principle of PBNCs, fusing the interleukin-4 receptor (IL-4R)-targeting peptide, AP-1, identified previously by phage display, with ferritin-L-chain (FTL), which undergoes 24-subunit assembly to form highly stable AP-1-containing nanocage proteins (AP1-PBNCs). AP1-PBNCs bound specifically to the IL-4R-expressing cell line, A549, and their binding and internalization were specifically blocked by anti-IL-4R antibody. AP1-PBNCs exhibited dramatically enhanced binding avidity to IL-4R compared with AP-1 peptide, measured by surface plasmon resonance spectroscopy. Furthermore, treatment with AP1-PBNCs in a murine model of experimental asthma diminished airway hyper-responsiveness and eosinophilic airway inflammation along with decreased mucus hyperproduction. These findings hold great promise for the application of various PBNCs with ligand-specific peptides in therapeutics for different diseases, such as cancer.

Reduction of the required number of electrical regenerators by physical layer impairment aware regenerator placement and routing (2008)

The number of OEO regenerators required for a fixed blocking probability in a translucent network can be reduced drastically, if physical layer impairments are considered during regenerator placement and routing.
Cycling with noncircular chainring system changes the three-dimensional kinematics of the lower limbs (2009)

This study investigated the three-dimensional (3-D) pedaling kinematics using a noncircular chainring system and a conventional system. Five cyclists pedaled at their preferred cadence at a workload of 300 W using two crank systems. Flexion/extension of the hip, knee and ankle as well as shank rotation, foot adduction/abduction, and pedal angle were measured. Joint range of motion (ROM) and angular displacements were compared between the systems. Sagittal plane ROM was significantly greater (P < 0.05) at the hip (noncircular system = 39 +/- 3 degrees; conventional system = 34 +/- 4 degrees) the knee (noncircular system = 69 +/- 4 degrees; conventional system = 57 +/- 10 degrees), and ankle (noncircular system = 21 +/- 2 degrees; conventional system = 19 +/- 4 degrees) resulting in greater pedal ROM (noncircular system = 43 +/- 3 degrees; conventional system = 37 +/- 5 degrees) while using the noncircular system. Shank rotation ROM was significantly lower (P < 0.05) while using the noncircular chainring (noncircular system = 10 +/- 1 degree; conventional system = 14 +/- 1 degree). These results support a significant effect of the noncircular chainring system on pedaling kinematics during submaximal exercise.
Identification of Proteins that Interact with TANK Binding Kinase 1 and Testing for Mutations Associated with Glaucoma (2013)

TAP showed that NAP1, TANK and TBKBP1 interact with TBK1 and are good candidates for contributing to NTG. A mutation screen of TANK detected three non-synonymous variants. Although, it remains possible that one or more of these TANK mutations may have a role in NTG, the data in this report do not provide statistical support for an association between TANK variants and NTG.
Genome-wide expression profiling in leaves and roots of date palm (Phoenix dactylifera L.) exposed to salinity (2017)

Leaf and root tissues respond differentially to salinity stress and this study has revealed genes and pathways that are associated with responses to elevated NaCl levels and thus may play important roles in salt tolerance providing a foundation for functional characterization of salt stress-responsive genes in the date palm.
A Pulse Combustion‐Spray Pyrolysis Process for the Preparation of Nano‐ and Submicrometer‐Sized Oxide Particles (2007)

The preparation of nano‐ and submicrometer particles using an integrated pulse combustion–spray pyrolysis process was investigated for the first time. Zinc oxide nanoparticles with average sizes ranging from 20 to 40 nm were synthesized using a salt precursor with a lower decomposition temperature than the pulse combustion (PC) temperature. Particles of a doped‐type oxide, gadolinium oxide‐doped with europium, were also produced from a precursor, whose decomposition temperature was higher than the PC temperature, and were observed to be ellipsoidal–toroidal in shape and submicrometer in size. The high‐intensity fluctuating pressures generated by PC and the precursor decomposition temperature are proposed as the reasons for the formation of either nanoparticles or aspherical particles. In addition, hot gas fluctuating flow in PC enhanced energy transfer, resulting in more crystalline particles, as compared with particles produced by conventional spray pyrolysis.
Conformational characteristics of rigid cyclic nucleotides. 2. The solution conformation of .alpha.-nucleoside 3',5'-cyclic monophosphates and the role of the 2'-hydroxyl group (1977)

Since the nineteenth century, access to and the development of natural resources became an important element of national and international politics. Resource security emerged as an issue vital to national security; and resource competition and crises gave rise to international tensions as well as to technological innovation and new modes of transnational cooperation.
A 10 bit, 300 MS/s Nyquist Current-Steering Power DAC With 6 V<formula formulatype="inline"><tex Notation="TeX">$_{\rm PP}$</tex> </formula> Output Swing (2014)

A 10 bit current-steering, digital-to-analog converter (DAC) is presented that delivers 6 V PP into a 100 Ω differential load. To realize high-voltage swings using fineline CMOS, a stacked-FET buffer is used to isolate the current source from the output load. The stacked-FET buffer degrades the linearity of the DAC. This work presents a Volterra analysis to capture the frequency-dependent behavior of the stacked-FET circuit that can be cascaded to quantify the linearity of an N-device stack. The power DAC is implemented in 45 nm CMOS SOI and the measured differential nonlinearity (DNL) and integral nonlinearity (INL) is better than 0.4 and 0.6 LSB, respectively. The DAC consumes 476 mW and achieves a peak SFDR of 73 dB and a minimum IM3 of -69 dBc. This DAC demonstrates the largest output swing and highest power efficiency for a high-resolution ( >8 bit), high-speed ( >100 MS/s) DAC.
Myocardial Conducting System Dysfunctions from Thoracic Impact (1978)

An analysis of electrocardiograms (ECG lead II) obtained following blunt thoracic impacts conducted on 12 anesthetized pigs indicated that all animals developed some degree of trauma to the heart conducting system: sino-atrial nodal disturbances, atrio-ventricular junctional dysfunction, intraventricular conduction defects (e.g., bundle branch blocks), or ventricular fibrillation. The induced ventricular fibrillation proceeded rapidly to the demise of four animals in this study. A comparison of the occurrence of ventricular fibrillation with measured biomechanical response parameters indicated a significant correlation of ventricular dysfunction with high levels of sternal acceleration (930 g) and impact velocity (10.7 m/s). The initiation of ventricular fibrillation did not correlate with typical biomechanical thoracic injury "indicators" (i.i., level of normalized thoracic deflection, cumulative AIS, peak spinal acceleration, or applied force). An injury severity classification (MCD) was subsequently developed for the evaluation of myocardial conducting system dysfunctions.

Microbial Production and Enzymatic Biosynthesis of γ-aminobutyric acid (GABA) Using<em> Lactobacillus plantarum</em> FNCC 260 Isolated From Indonesian Fermented Foods (2020)

In the present study, we isolated and screened thirty strains of GABA-producing lactic acid bacteria (LAB) from Indonesian traditional fermented foods. Two strains were able to convert monosodium glutamate (MSG) to GABA after 24 h of cultivation at 37oC based on thin layer chromatography (TLC) screening. 16S rDNA sequencing and proteomic identification using MALDI-TOF MS identified these two strains as Lactobacillus plantarum designated as L. plantarum FNCC 260 and L. plantarum FNCC 343. The highest yield of GABA production obtained from the fermentation of L. plantarum FNCC 260 was 809.2 mg/l of culture medium after 60 h of cultivation. Supplementation of 0.6 mM pyridoxal 5&amp;rsquo;-phosphate (PLP) and 0.1 mM pyridoxine led to the increase in GABA production to 945.3 mg/l and 969.5 mg/l, respectively. The highest GABA production of 1226.5 mg/l of culture medium was obtained with 100 mM initial concentration of MSG added in the cultivation medium. The open reading frame (ORF) of 1410 bp of the gadB gene from L. plantarum FNCC 260 encodes 469 amino acids with a calculated molecular mass of 53.57 kDa. The production of GABA via enzymatic conversion of monosodium glutamate (MSG) using purified recombinant glutamate decarboxylase (GAD) from L. plantarum FNCC 260 expressed in Escherichia coli was found to be more efficient (5-fold higher within 6 h) than the production obtained from fermentation. L. plantarum FNCC 260 could be of interest for the synthesis of GABA.
Multidimensional Linear Cryptanalysis (2018)

Linear cryptanalysis introduced by Matsui is a statistical attack which exploits a binary linear relation between plaintext, ciphertext and key, either in Algorithm 1 for recovering one bit of information of the secret key of a block cipher, or in Algorithm 2 for ranking candidate values for a part of the key. The statistical model is based on the expected and observed bias of a single binary value. Multiple linear approximations have been used with the goal to make the linear attack more efficient. More bits of information of the key can potentially be recovered possibly using less data. But then also more elaborated statistical models are needed to capture the joint behaviour of several not necessarily independent binary variables. Also more options are available for generalising the statistics of a single variable to several variables. The multidimensional extension of linear cryptanalysis to be introduced in this paper considers using multiple linear approximations that form a linear subspace. Different extensions of Algorithm 1 and Algorithm 2 will be presented and studied. The methods will be based on known statistical tools such as goodness-of-fit test and log-likelihood ratio. The efficiency of the different methods will be measured and compared in theory and experiments using the concept of advantage introduced by Selçuk. The block cipher Serpent with a reduced number of rounds will be used as test bed. The multidimensional linear cryptanalysis will also be compared with previous methods that use biasedness of multiple linear approximations. It will be shown in the simulations that the multidimensional method is potentially more powerful. Its main theoretical advantage is that the statistical model can be given without the assumption about statistical independence of the linear approximations.

A giant splitting (DeltaSigma <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">LP</sub> 240 meV) of the lower polariton branch is observed.
Cellular neuroplasticity mechanisms mediating pain persistence. (2004)

Transmission of noxious-stimulus-evoked inputs in the spinal and trigeminal systems is mediated primarily through excitatory glutamatergic synapses using alpha amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA), kainate and N-methyl-D-aspartate (NMDA) subtypes of glutamate receptors. Glutamatergic synapses exhibit multiple forms of short-lasting and long-lasting synaptic plasticity. Persistent enhancement of nociceptive transmission, known as "central sensitization," is a form of lasting plasticity that is similar mechanistically to long-term potentiation of glutamatergic transmission in other regions of the central nervous system. This potentiation of AMPA/kainate transmission is dependent upon the activity of NMDA receptors, which become enhanced following noxious peripheral stimulation as a result of several convergent mechanisms. Central sensitization is thus an expression of increased synaptic gain at glutamatergic synapses in central nociceptive-transmission neurons and thereby contributes importantly to pain hypersensitivity. In addition, recent evidence has revealed a new player in the mechanisms underlying pain hypersensitivity following nerve injury--microglia. Understanding of the roles of microglia may lead to new strategies for the diagnosis and management of neuropathic pain.
Disc Design for Reduction of Random Data Bit Error Rate in Super-Resolution (2007)

To improve the readout signal quality for 3-Dimentional Pit Selection (3DPS), we designed new disc structure to suppress the normal-resolution signal which causes the noise of the readout signal. Using the disc with new structure which takes advantage of 3DPS, signal amplitude ratio of the normal-resolution to the super-resolution was reduced to be less than 0.5 which satisfies bit error rate of less than 10−5.
Nonlinear dynamics of bubbles with surfactants (1998)

Hugh Flynn pioneered many aspects of cavitational phenomena. He even got a patent on the idea that large bubble collapse could be used for inertially induced thermonuclear fusion. Some researchers currently working in the area of sonoluminescence are asking the same questions. One of the key requirements for confining the energy in the collapse of a bubble is maintaining spherical symmetry. Instabilities, such as Rayleigh–Taylor and Kelvin–Helmholtz, can compromise this requirement. Therefore it is useful to examine the role of surfactants in conferring stability on the collapse of bubbles. Codes that have recently permitted the description of superoscillations of liquid drops with surfactants in air [e.g., Apfel et al., Phys. Rev. Lett. 78, 1912–1915 (1997)] can be applied to the case of a bubble in a liquid. Of particular interest are insoluble surfactants, such as bovine serum albumin, which do not reduce the surface tension that much, but which greatly increase the surface damping. The role of damping in discouraging or delaying instability of collapsing bubbles in an acoustic field will be presented.

Design analysis of touch chip for enhanced package and board level reliability (2005)

Touch chip, a unique bio-sensor to recognize fingerprint of users, is ideally suited for portable consumer applications such as mobile phones, remote controls, tablet PCs, PDAs, and ultra-thin laptop computers as security system. Modeling is a useful and efficient tool for design analysis. In this paper, both package and board level modeling are performed for touch strip, a new generation of touch chip design. The fatigue life, failure location and crack interface of the critical solder ball during thermal cycling test are predicted. It covers 14 design parameters for solder joint reliability analysis, i.e. die size and thickness, substrate thickness, board thickness, mold compound thickness, solder ball geometry, die attach and mold compound material properties, inclusion of polyimide layer, and temperature cycling range. Package level stress analysis is investigated for polyimide thickness and modulus. The findings help to design a more reliable touch chip at both package and board levels.

Validation and normalization of the Japanese version of BRIEF among junior high school students (2017)

This study sought to examine the reliability and validity of the Japanese version of the Behavior Rating Inventory of Executive Function (J-BRIEF). In this study, BRIEF was administered to evaluate executive function in everyday life in 91 subjects with autism spectrum disorder (ASD; ages 12–15; 72 boys) and 2,230 community samples (CS; ages 12–15; 1,083 boys). For this purpose, we applied categorical confirmatory factor analysis, which revealed that the scale was composed of two factors and eight subscales of the high test-retest stability. Reliability was confirmed using an external criterion (ADHD-Rating scale: ADHD-RS). Receiver operating characteristic analysis revealed an optimal cut-off of 118.5 (sensitivity = 0.811, specificity = 0.828). This study confirmed the reliability and the validity of J-BRIEF.
