Porous 3D Prussian blue/cellulose aerogel as a decorporation agent for removal of ingested cesium from the gastrointestinal tract (2018)

In the present study, we successfully synthesized a porous three-dimensional Prussian blue-cellulose aerogel (PB-CA) composite and used it as a decorporation agent for the selective removal of ingested cesium ions (Cs<sup>+</sup>) from the gastrointestinal (GI) tract. The safety of the PB-CA composite was evaluated through an in vitro cytotoxicity study using macrophage-like THP-1 cells and Caco-2 intestinal epithelial cells. The results revealed that the PB-CA composite was not cytotoxic. An adsorption study to examine the efficiency of the decorporation agent was conducted using a simulated intestinal fluid (SIF). The adsorption isotherm was fitted to the Langmuir model with a maximum Cs<sup>+</sup> adsorption capacity of 13.70 mg/g in SIF that followed pseudo-second-order kinetics. The PB-CA composite showed excellent stability in SIF with a maximum Cs<sup>+</sup> removal efficiency of 99.43%. The promising safety toxicology profile, remarkable Cs<sup>+</sup> adsorption efficacy, and excellent stability of the composite demonstrated its great potential for use as an orally administered drug for the decorporation of Cs<sup>+</sup> from the GI tract.

The Characteristics of Bi-2223/Ag Conductor for High Field Application (2008)

For the development of high magnetic field application using high temperature superconductor (HTS), Bi-2223/Ag tape is one of the promising materials because of its high current capacity and upper critical field. However, Bi-2223/Ag tape shows very strong anisotropy and significant deterioration of critical current in the magnetic field. To explore the possibility of HTS in high field applications, we evaluated the critical current and index value of Bi-2223/Ag conductor in high magnetic field. The Bi-2223/Ag tape was characterized as a function of increasing and decreasing field. The temperature dependence was also examined lower than 4.2 K. All measurements were carried out with hybrid magnet system up to 30 T and the experimental results are reported.
중심-측두부 극파와 동반된 소아기 간질의 임상적 연구 (1994)

This study was retrospectively undertaken to evaluate clinical manifestations, electroencephalographic findings, response to antiepileptic drugs and prognosis of 80 benign childhood epilepsy with centrotemporal spikes (BCECT) patients seen between 1967 and 1993 and followed up for more than 2 years. \nThe age of onset ranges from 3 to 15 years. In 93 percent of patients, seizures appeared between 4 to 12 year-old, with peak of 5 year-old. \nThe main manifestations of partial seizure were hemifacial spasm (53%) and oropharygeal signs (52%) with hypersalivation, abnormal sensation of mouth, gutteral sounds, swallowing difficulty and feeling of suffocation. The types of seizure consist of partial seizure(66%) and partial seizure with secondary generalization (34%). \nDistributions of seizure attack were nocturnal sleep (83%), diurnal sleep state(4%) and waking state (13%). \nThe typical EEG findings were slow diaphasic high voltage centrotemporal spikes with unilateral (94%) and bilateral foci(6%) with normal background. \nIn addition to typical EEG findings, there were associated with multifocal independent sharp-waves (8.9%) and generalized sharp-wave discharges (7.8%). \nBCECT patients were well controlled by antiepileptic drugs and had good prognosis. \nDuring the follow-up period (2-17years), we observed that all patient were well adapted to school and society. Seizures did not occur after adolescent period.
Comparison of two promoters controlling expression of secreted or intracellular IL-1 receptor antagonist. (1994)

IL-1R antagonist can be expressed as a secreted glycoprotein (sIL-1Ra) or as an intracellular nonglycosylated form (icIL-1Ra). The two isoforms only differ in their N-terminal sequences and are thought to originate, by selection of alternative first exons, from a single gene (IL-1RN). We have previously described a clone that encodes the exons and promoter for sIL-1Ra. In this work, we describe and characterize a clone that contains the further upstream, alternative first exon used to generate icIL-1Ra. Sequences upstream to this alternative exon are demonstrated to have promoter activity in the human colon epithelial cell line HT29, whereas the sIL-1Ra promoter has undetectable activity. Both the icIL-1Ra and sIL-1Ra promoters were active when transfected into THP-1 cells. Neither promoter was responsive to PMA or LPS when introduced into HT29 or THP-1 cells. Activity of the endogenous icIL-1Ra and sIL-1Ra promoters was also investigated. In agreement with the transfected icIL-1Ra promoter, the endogenous icIL-1Ra gene is active in HT29 cells, though induced by PMA. In contrast to the transfected icIL-1Ra promoter, the endogenous icIL-1Ra gene is inactive in THP-1 cells and induced by PMA. Our data complete the structure of the human IL-1RN gene, demonstrating that the two forms of IL-1Ra are produced from the same gene by use of alternative first exons. We also show that there are two distinct promoters that control IL-1Ra expression, that lie upstream to each alternative first exon.
High-Strength Nanostructured Films Based on Well-Preserved α-Chitin Nanofibrils Disintegrated from Insect Cuticles (2019)

The α-chitin nanofibril is an alternative to nanocellulose as a building-block for strong films and other nanomaterials. The hypothesis of high film strength for films based on mildly treated insect cuticles was tested. Fibrils from the cuticle of <i>Ruspolia differens</i> (a long-horned bush cricket grasshopper locally known as senene) are disintegrated by a mild process, subsequently characterized by transmission electron microscopy, NMR, Fourier transform infrared spectroscopy, and XRD, and used to prepare strong and transparent films. A mild process (with 20% NaOH treatment for 2 weeks and at room temperature) was used to largely remove the strongly bound protein associated with chitin. The purpose was to reduce chitin degradation. The native structure of chitin was indeed well preserved and close to the native state, as is supported by data for degree of acetylation, molar mass, crystallinity, and crystallite dimensions. The diameter of the smallest chitin fibrils was as small as 3-7 nm (average 6 nm) with lengths larger than or around 1 μm. A stable and well-dispersed colloidal chitin fibril suspension in water was achieved. A nanostructured chitin film prepared by filtration showed high optical transmittance (∼90%) and very high tensile strength (220 MPa). The high tensile strength was attributed to the well-preserved chitin structure, high intrinsic fibril strength, and high colloidal stability of the fibril suspension. Strong, transparent insect chitin films offer interesting alternatives to nanocellulose films because of different resource origins, surface chemistries, and potential antimicrobial properties.
560 nm InGaN micro-LEDs on low-defect-density and scalable (20-21) semipolar GaN on patterned sapphire substrates (2020)

We demonstrate InGaN-based semipolar 560 nm micro-light-emitting diodes with 2.5% EQE on high-quality and low-defect-density (20-21) GaN templates grown on scalable and low-cost sapphire substrates. Through transmission electron microscopy observations, we discuss how the management of misfit dislocations and their confinement in areas away from the active light-emitting region is necessary for improving device performance. We also discuss how the patterning of semipolar GaN on sapphire influences material properties in terms of surface roughness and undesired faceting in addition to indium segregation at the proximity of defected areas.

A General model to predict the iron losses in inverter fed induction motors (2009)

This paper presents an accurate and efficient method for predicting the iron losses in PWM inverter-fed induction motors. The method was initially proposed for the prediction of iron losses in non-oriented soft magnetic material with the same supply conditions. The proposed method requires the separation of the iron losses in the hysteresis and eddy current components and the average rectified and RMS of the PWM voltage values. Starting from the iron losses measured with sinusoidal supply and the PWM waveform characteristics, a fast and reliable prediction of the iron losses in the motor with the new voltage supply can be obtained. The proposed method has been proved on an induction motor prototype capable of providing good accuracy in iron loss measurement. The comparison between the measured and predicted iron losses with PWM supply have shown excellent agreement, confirming the validity of the method.
Advanced process control of a CVD tungsten reactor (1996)

An advanced multivariable in-line process control system, which combines traditional statistical process control (SPC) with feedback control, has been applied to the CVD tungsten process on an Applied Materials reactor. The goal of the model-based controller is to compensate for shifts in the process and maintain the wafer-state responses on target. The controller employs measurements made on test wafers to track the process behavior. This is accomplished by using model-based SPC, which compares the measurements with predictions obtained from process models. The process models relate the equipment settings to the wafer-state responses of interest. For CVD tungsten, a physically-based modeling approach was employed based on the reaction rate for the H/sub 2/ reduction of WF/sub 6/. The Arrhenius relationship for the kinetic model was linearized so that empirical modeling techniques could be applied. Statistically valid models were derived for deposition rate, film stress, and bulk resistivity using stepwise least-squares regression. On detecting a statistically significant shift in the process, the controller calculates adjustments to the settings to bring the process responses back on target. To achieve this, two additional test wafers are processed at slightly different settings than the current recipe. This local experiment allows the models to be updated to reflect the current process state. The model updates are expressed as multiplicative or additive changes in the process inputs and a change in the model constant. This approach for adaptive control also provides a diagnostic capability regarding the cause of the process shift. The adapted models are used by an optimizer to compute new settings to bring the responses back to target. The optimizer is capable of incrementally entering controllables into the strategy, reflecting the degree to which the engineer desires to manipulate each setting. The capability of the controller to compensate for induced shifts in the CVD tungsten process is demonstrated. Targets for film bulk resistivity and deposition rate were maintained while satisfying constraints on film stress and WF/sub 6/ conversion efficiency. The ability of the controller to update process models during routine operation is also investigated. The tuned process models better predict the process behavior over time compared to the untuned models and lead to improved process capability.
It takes two (2010)

Chromosome pairing is involved in X chromosome inactivation, a classic instance of monoallelic gene expression. Antigen receptor genes are also monoallelically expressed ("allelically excluded") by B and T lymphocytes, and we asked whether pairing contributed to the regulation of V(D)J recombination at these loci. We found that homologous immunoglobulin (Ig) alleles pair up during recombination. Homologous Ig pairing is substantially reduced in the absence of the RAG1/RAG2 recombinase, but a transgene expressing an active site RAG1 mutant (which binds but does not cleave DNA) rescues pairing in Rag1(-/-) developing B cells. RAG-mediated cleavage on one allele induces the other allele to relocate to pericentromeric heterochromatin (PCH), likely to ensure that only one allele is cut at a time. This relocation to PCH requires the DNA damage sensor ATM (ataxia telengiectasia mutated). In the absence of ATM, repositioning at PCH is diminished and the incidence of cleavage on both alleles is significantly increased. ATM appears to be activated by the introduction of a double-strand break on one allele to act in trans on the uncleaved allele, repositioning or maintaining it at PCH, to prevent bi-allelic recombination and chromosomal translocations.
Magnesium Phosphides–Synthesis and Structure of [Mg(PHPh)2(tmeda)] (1987)

Application as PR transfer reagents is for-seen for the new inorganic magnesium reagents [Mg(PHPh)2]∞ and the crystalline, monomeric title compound 1. The latter was prepared in high yield by monometalation of PhPH2 with the versatile reagent nBusBuMg and addition of TMEDA. In 1 the MgP distances are equal but the MgPC angles are not.
The error assessment in case of using two models for the displacement of a linear spring (2019)

Abstract The displacement of the free end of a spring is not always an axial displacement. In some circumstances, the free end of the spring displaces along a circular trajectory, and the spring elongation is considered approximately equal to its axial displacement. Such an approximation is used for modelling the suspension of railway wagons. The present work purpose is to exactly determine the elastic force in case of spring free end circular displacement, in order to compute the error of considering this displacement equal to the spring axial displacement. Then, the real dynamic behavior of the model is compared with the approximate one, by numerical simulation.
A magnetoacoustic keyboard (1979)

A keyboard which minimizes electrical interconnections and is naturally suited for microprocessor applications has been developed using a magnetoacoustic delay line. The delay line utilizes a 2 μmeter magnetostrictive 50:50 NiFe plating on a 125 μmeter BeCu <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> wire, fabricated with a circumferential easy axis. The wire is formed in a serpentine shape to pass under all the keys. The keys contain low-intensity molded permanent magnets which can rotate the magnetization from the circumferential direction. An interrogation current pulse in the wire generates acoustic waves under each depressed key, which propagate to a sense coil where the torsional waves are sequentially sensed. Each interrogation pulse from the microprocessor produces a list with the status of every key.
Programmable Liquid Crystal Elastomers Prepared by Thiol-Ene Photopolymerization (Postprint) (2015)

Abstract : The spontaneous conversion of a flat film into a 3-D shape requires local programming of the mechanical response. Historically, the ability to locally program the mechanical response of high strain (30 ) liquid crystalline elastomers (LCEs) has been limited to magnetic or mechanical alignment techniques, which limits spatial resolution. Recently, we reported on the preparation of LCEs capable of 55 strain with spatial control of the mechanical response at scales as small as 0.01 mm2. Here, we report a distinct formulation strategy to realize programmable stimulus-response in LCEs. Photopolymerization of thiolene/acrylate formulations yields materials that exhibit large reversible strain up to 150 . The photopolymerization reaction is extremely rapid, reducing preparation time from days to minutes. The mechanical behavior of these materials can be tuned by varying cross-link density. Spatial and hierarchical programming of the director profile is demonstrated, enabling 3-D shape change, including twisting ribbons and localized Gaussian curvature.
Exact rebinning methods for three-dimensional PET (1999)

The high computational cost of data processing in volume PET imaging is still hindering the routine application of this successful technique, especially in the case of dynamic studies. This paper describes two new algorithms based on an exact rebinning equation, which can be applied to accelerate the processing of three-dimensional (3-D) PET data. The first algorithm, FOREPROJ, is a fast-forward projection algorithm that allows calculation of the 3-D attenuation correction factors (ACF's) directly from a two-dimensional (2-D) transmission scan, without first reconstructing the attenuation map and then performing a 3-D forward projection. The use of FOREPROJ speeds up the estimation of the 3-D ACF's by more than a factor five. The second algorithm, FOREX, is a rebinning algorithm that is also more than five times faster, compared to the standard reprojection algorithm (3DRP) and does not suffer from the image distortions generated by the even faster approximate Fourier rebinning (FORE) method at large axial apertures. However, FOREX is probably not required by most existing scanners, as the axial apertures are not large enough to show improvements over FORE with clinical data. Both algorithms have been implemented and applied to data simulated for a scanner with a large axial aperture (30 degrees), and also to data acquired with the ECAT HR and the ECAT HR+ scanners. Results demonstrate the excellent accuracy achieved by these algorithms and the important speedup when the sinogram sizes are powers of two.

A novel solid-state image sensor for image recording at 2,000 frames per second (1981)

A very high-speed image sensor for image recording at up to 2,000 full or 12,000 partial frames per second consists of a 192 V × 248 H array of photocapacitors. For high-speed operation, the image-sensing area is divided into six blocks, each block having 32 parallel outputs. The blocks are addressed sequentially, and the 32 outputs are sensed simultaneously. The sensor dynamic range is 46 dB at 2,000 fps. Spectral sensitivity, noise, and spatial resolution are discussed.
Diphosphine Oxide Catalyzed Direct Aldol Reactions (2010)

A highly stereoselective direct aldol reaction of ketones 2 to aromatic aldehydes 1 mediated by Lewis base catalyst 3 is reported. During this reaction, trichlorosilyl enolethers are generated in situ from ketones and tetrachlorosilane (three equivalents), and then activated by coordinating to the chiral diphosphine oxide catalysts. The coordination of aldehydes to the chiral cationic hypervalent silicon species has shown to be crucial for high diastereo- and enantioselectivities (see the proposed model). Both electron-rich and -poor aromatic aldehydes are tolerated with high level of stereoselectivity, but aliphatic aldehyde acceptors did not show any reactivity even at 0 ˚C. The cross-condensation of benzaldehydes with α-branched aldehydes also proceeds well under these reaction conditions.
The first direct probing of porosity on supported mesoporous silica thin films through hyperpolarised129Xe NMR (2002)

The continuous flow hyperpolarised (HP) 129Xe NMR technique has been used for the first time on mesoporous silica thin films. This study demonstrates the possibility of recording information about the porosity of a very small quantity of materials and the high sensitivity of the NMR response to pore size and pore functionality.

A joint effort to deliver satellite retrieved atmospheric CO 2 concentrations for surface flux inversions: the ensemble median algorithm EMMA (2012)

Abstract. We analyze an ensemble of seven XCO2 retrieval algorithms for SCIAMACHY and GOSAT. The ensemble spread can be interpreted as regional uncertainty and can help to identify locations for new TCCON validation sites. Additionally, we introduce the ensemble median algorithm EMMA combining individual soundings of the seven algorithms into one new dataset. The ensemble takes advantage of the algorithms' independent developments. We find ensemble spreads being often &lt;1 ppm but rising up to 2 ppm especially in the tropics and East Asia. On the basis of gridded monthly averages, we compare EMMA and all individual algorithms with TCCON and CarbonTracker model results (potential outliers, north/south gradient, seasonal (peak-to-peak) amplitude, standard deviation of the difference). Our findings show that EMMA is a promising candidate for inverse modeling studies. Compared to CarbonTracker, the satellite retrievals find consistently larger north/south gradients (by 0.3 ppm–0.9 ppm) and seasonal amplitudes (by 1.5 ppm–2.0 ppm).

Medications Are Associated with Falls in People with Multiple Sclerosis (2015)

Reporting use of more medications and more neurologically active medications is associated with falls and injurious falls in people with MS. Close evaluation of the need for each medication, with associated minimization of neurologically active medications in patients with MS, may help prevent falls. Use of MS disease-modifying therapies may be associated with fewer falls. This relationship needs further evaluation.
