1THz one-sided directional slot antenna on a chip connected with InAs HEMT (2020)

Terahertz (THz) range holds between infrared light and millimeter wave or microwave radiation. Moreover, THz waves is highly attenuated by the metal object or sensitive to an inter-molecular binding force. Therefore, imaging using THz range is attracted much attention for security, manufacturing, chemical imaging, and so on. In our research, the THz detector composed of Indium arsenide (InAs) high electron mobility transistor (HEMT) and one-sided directional slot antenna on a chip will be developed. In this paper, we focused on the antenna on a chip. The proposed antenna has three layers, namely, top antenna metal, dielectric substrate (BCB, benzocyclobutene) and bottom floating metal layer. There are a coplanar (CPW) feed lines and slots on the top antenna metal. By optimizing the size of the bottom floating metal layer, the radiation toward the back side is suppressed. The CPW feed line is connected the gate electrode on the InAs HEMT. In order to maximize the receiving THz signal form the antenna to InAs HEMT, antenna and gate input impedance is characterized by using the 3D electromagnetic simulator. It has been found that when the input impedance of the gate electrode changes from 10 ohms to 50 ohms, the voltage generated at the gate electrodes is tripled. The antenna was fabricated by the conventional photolithography process. The size of the radiation metal is 290 &mu;m x 210 &mu;m on the top metal with probe pads. The measured antenna gain is 5.57 dBi at 0.93 THz compared with the 5.96 dBi antenna gain at 1 THz from the simulation.
A {Ni12}‐Wheel‐Based Metal–Organic Framework for Coordinative Binding of Sulphur Dioxide and Nitrogen Dioxide (2021)

Abstract Air pollution by SO 2 and NO 2 has caused significant risks on the environment and human health. Understanding the mechanism of active sites within capture materials is of fundamental importance to the development of new clean‐up technologies. Here we report the crystallographic observation of reversible coordinative binding of SO 2 and NO 2 on open Ni II sites in a metal‐organic framework (NKU‐100) incorporating unprecedented {Ni 12 }‐wheels; each wheel exhibits six open Ni II sites on desolvation. Immobilised gas molecules are further stabilised by cooperative host‐guest interactions comprised of hydrogen bonds, π⋅⋅⋅π interactions and dipole interactions. At 298 K and 1.0 bar, NKU‐100 shows adsorption uptakes of 6.21 and 5.80 mmol g −1 for SO 2 and NO 2 , respectively. Dynamic breakthrough experiments have confirmed the selective retention of SO 2 and NO 2 at low concentrations under dry conditions. This work will inspire the future design of efficient sorbents for the capture of SO 2 and NO 2 .

Disturbances in affective communication following brain injury (2004)

While both patient groups performed significantly worse than the control group on affect expression, perception and spontaneity (p<0.01), the CVA group performed significantly worse than the TBI group (p<0.01) on affect perception. Results of this study document disturbances in affect in brain injured patients and highlight the importance of assessing affect during early recovery.
New Iron-Based Mixed-Polyanion Cathodes for Lithium and Sodium Rechargeable Batteries: Combined First Principles Calculations and Experimental Study (2012)

New iron-based mixed-polyanion compounds LixNa4-xFe3(PO4)(2)(P2O7) (x = 0-3) were synthesized, and their crystal structures were determined. The new compounds contained three-dimensional (3D)-sodium/lithium paths supported by P2O7 pillars in the crystal. First principles calculations identified the complex 3D paths with their activation barriers and revealed them as fast ionic conductors. The reversible electrode operation was found in both Li and Na cells with capacities of one-electron reaction per Fe atom, 140 and 129 mAh g(-1), respectively. The redox potential of each phase was similar to 3.4 V (vs Li) for the Li-ion cell and similar to 3.2 V (vs Na) for the Na-ion cell. The properties of high power, small volume change, and high thermal stability were also recognized, presenting this new compound as a potential competitor to other iron-based electrodes such as Li2FeP2O7, Li2FePO4F, and LiFePO4.

The Elastic Scattering of Deuterons by Tritons (1952)

The differential cross section for the elastic scattering of deuterons by tritons has been measured in the energy range 0.96 Mev to 3.22 Mev. The angular range of data is between 44.3\ifmmode^\circ\else\textdegree\fi{} and 126.4\ifmmode^\circ\else\textdegree\fi{} in the center-of-mass system of coordinates. The values of the cross section have a minimum near 90\ifmmode^\circ\else\textdegree\fi{}, and this minimum decreases steadily and moves to higher angles as the incident deuteron energy is increased. At 1.20 Mev the cross section at the minimum is equal to 0.130 barn, and at 3.22 it is 0.019 barn.
Decreased methylation of the major mouse long interspersed repeated DNA during aging and in myeloma cells (1986)

Sequences of DNA that hybridize on Southern blots with cloned EcoR1 1.3 kb (ER1) of long interspersed repeated sequence (L1Md) of mouse have been examined in genomic DNA of neonatal mice, livers and brains of adult mice (3, 10, 27, and 30 mo old), and the solid myeloma tumor MOPC-315. The isoschizomers Hpa II (CCGG or mCCGG) and Msp I (CCGG or CmCGG) were used to assess methylation. We found that the L1Md sequence is fully methylated in young animals but demethylated in myeloma. Demethylation of L1Md sequence also occurred in aged animals. By scanning the autoradiogram, we found that approximately 8% of the 10(4)-10(5) copies have been demethylated in 27-mo-old liver.
[Our experience using free vascularized bone flaps in mandibular reconstruction. The external brachial flap, the fibular flap, the para-scapular flap]. (1993)

New techniques developed over the last decade use vascularized bone flaps for maxillofacial reconstructive surgery. Indications for use of three recently described flaps (external brachial, fibular, parascapular) are discussed as a function of the regions to be reconstructed. Three clinical cases are presented, each patient having received one type of flap.
Whole saliva and the diagnosis of Sjögren's Syndrome: an evaluation of patients who complain of dry mouth and dry eyes. Part 2: Immunologic findings (1996)

The findings in Part 1 of this study, of patients who had complained of dry mouth and dry eyes, suggest that those patients, who demonstrated low resting and stimulated flow rates and had lacrimal hypofunction, suffered from SS. The observation in this paper, that the whole saliva of these patients contains the SS antibodies, confirms this diagnosis. The data suggest that whole saliva can be used to establish the diagnosis of SS and other autoimmune diseases.
Effect of surface cleaning on seam quality of laser beam welded mixed joints (2023)

In this study, different surface cleaning methods were used to remove greases and oils from the surface of the E235 steel tube component of the diamond segmented drill bit before laser beam welding. The mechanical, chemical and electromechanical cleaning methods were selected because they are suitable for removing greases and oils adhering to the surface during tube production. The cleaned samples were successfully welded using the same heat inputs by laser welding. The effect of mechanical processes with sandblasting and dry-ice blasting, chemical processes with isopropyl alcohol, acetone and alkaline acidic liquid, electromechanical process with a laser beam on micro-computer tomography, break-out value and micro-hardness measurement examined. The cleanliness of the surfaces and strength of the laser-welded joint was inferred from the break-out value (BOV), as this is the principal qualification value in mass production. The results were compared to the untreated sample. According to the results obtained in this study, any defects in the seams were analyzed, and no cracks founded by computer tomography. According to a shade of grey diagram, all the pretreated samples had a higher absorption than the untreated sample. While the chemical methods had a significant effect (59-66%), the mechanical and electromechanical methods had a positive effect (22-48%) compared to the untreated sample. In addition, the break-out values showed that the mechanical methods had a significantly higher effect (19%) than the other surface cleaning methods. This test showed different results from the micro-CT scan. The microhardness test showed no difference between the hardnesses of the cleaned and uncleaned samples and no difference in seam thicknesses. The optimal oil removal process discusses in the conclusion part.
Learning non-homogenous textures and the unlearning problem with application to drusen detection in retinal images (2008)

In this work we present a novel approach for learning non- homogenous textures without facing the unlearning problem. Our learning method mimics the human behavior of selective learning in the sense of fast memory renewal. We perform probabilistic boosting and structural similarity clustering for fast selective learning in a large knowledge domain acquired over different time steps. Applied to non- homogenous texture discrimination, our learning method is the first approach that deals with the unlearning problem applied to the task of drusen segmentation in retinal imagery, which itself is a challenging problem due to high variability of non-homogenous texture appearance. We present preliminary results.
Influence of the composition of aqueous dimethylsulfoxide solvent on thermodynamics of complexing between 18-crown-6-ether and D,L-alanine (2012)

Standard thermodynamic parameters (logK o, Δr H o, TΔr S o) of complexing 18-crown-6 ether (18C6) with D,L-alanine (Ala) in mixed water-dimethysulfoxide (H2O-DMSO) solvents are calculated on the basis of calorimetric titration results. A rise in the DMSO concentration in mixed solvent is found to increase stability and increase the exothermicity of the formation of [Ala-18C6] molecular complex. Changes in the reaction energetic are shown to be determined by changes in the solvation state of 18C6 that is the characteristic of the reactions of molecular complex formation between 18C6 and D,L-alanine or glycine in water-organic solvents.

The Genetic Basis of Quality of Life in Healthy Swedish Women: A Candidate Gene Approach (2015)

If validated, the involvement of GSTZ1 in cognitive functioning underscores its heritability which is likely the result of differences in the dopamine pathway, as GSTZ1 contributes to the equilibrium between dopamine and its neurotoxic metabolites via the glutathione redox cycle.
cAMP signaling regulates DNA hydroxymethylation by augmenting the intracellular labile ferrous iron pool (2017)

It is widely accepted that cAMP regulates gene transcription principally by activating the protein kinase A (PKA)-targeted transcription factors. Here, we show that cAMP enhances the generation of 5-hydroxymethylcytosine (5hmC) in multiple cell types. 5hmC is converted from 5-methylcytosine (5mC) by Tet methylcytosine dioxygenases, for which Fe(II) is an essential cofactor. The promotion of 5hmC was mediated by a prompt increase of the intracellular labile Fe(II) pool (LIP). cAMP enhanced the acidification of endosomes for Fe(II) release to the LIP likely through RapGEF2. The effect of cAMP on Fe(II) and 5hmC was confirmed by adenylate cyclase activators, phosphodiesterase inhibitors, and most notably by stimulation of G protein-coupled receptors (GPCR). The transcriptomic changes caused by cAMP occurred in concert with 5hmC elevation in differentially transcribed genes. Collectively, these data show a previously unrecognized regulation of gene transcription by GPCR-cAMP signaling through augmentation of the intracellular labile Fe(II) pool and DNA hydroxymethylation.
Electrocardiograph (ECG) Circuit Design and Software-based Processing using LabVIEW (2017)

The efficiency and acquisition of a clean (diagnosable) ECG signal dependent upon the proper selection of electronic components and the techniques used for noise elimination. Given that the human body and the lead cables act as antennas, hence picking up noises from the surroundings, thus a major part in the design of an ECG device is to apply various techniques for noise reduction at the early stage of the transmission and processing of the signal. This paper, therefore, covers the design and development of a Single Chanel 3-Lead Electrocardiograph and a Software-based processing environment. Main design characteristics include reduction of common mode voltages, good protection for the patient, use of the ECG device for both monitoring and automatic extraction (measurements) of the ECG components by the software. The hardware consisted of a lead selection stage for the user to select the bipolar lead for recording, a pre-amplification stage for amplifying the differential potentials while rejecting common mode voltages, an electrical isolation stage from three filtering stages with different bandwidths for noise attenuation, a power line interference reduction stage and a final amplification stage. A program in LabVIEW was developed to further improve the quality of the ECG signal, extract all its features and automatically calculate the main ECG output waveforms. The program had two main sections: The filtering section for removing power line interference, wideband noises and baseline wandering, and the analysis section for automatically extracting and measuring all the features of the ECG in real time. A Front Panel Environment was, therefore, developed for the user interface. The present system produced ECG tracings without the influence of noise/artefacts and provided accurate detection and measurement of all the components of the ECG signal.
High-operating temperature MWIR photon detectors based on Type II InAs/GaSb superlattice (2011)

Recent efforts have been paid to elevate the operating temperature of Type II superlattice Mid Infrared photon detectors. Using M-structure superlattice, novel device architectures have been developed, resulting in significant improvement of the device performances. In this paper, we will compare different photodetector architectures and discuss the optimization scheme which leads to almost one order of magnitude of improvement to the electrical performance. At 150K, single element detectors exhibit a quantum efficiency above 50%, and a specific detectivity of 1.05x10<sup>12</sup> cm.Hz<sup>1/2</sup>/W. BLIP operation with a 300K background and 2&pi; FOV can be reached with an operating temperature up to 180K. High quality focal plane arrays were demonstrated with a noise equivalent temperature difference (NEDT) of 11mK up to 120K. Human body imaging is achieved at 150K with NEDT of 150mK.
Neutron Magnetic Scattering from Rare-Earth Ions (1962)

The theory of neutron scattering by paramagnetic rare-earth ions has been given by Trammell and more recently by Odiot and Saint-James. Unlike the case for the iron series transition metals, for which the orbital angular momentum of the 3d electrons is almost completely quenched, the magnetic scattering of neutrons from the rare earths (except for gadolinium and europium) arises from both the spin and orbital contributions to the magnetization. Using recently determined Hartree-Fock wave functions for some of the trivalent rare-earth ions we have determined the functions 〈jn〉 and 〈gn〉 (for n=0, 2, 4, and 6) which are necessary for the theoretical evaluation of the spin and orbital contributions respectively to the magnetic form factor. A comparison of these theoretical results with the experiments of Koehler and Wollan for Nd3+ and Er3+ and of Koehler, Wollan and Wilkinson for Ho3+ is presented. Differences are found between theory and experiment and some possible reasons for this are discussed. A paper on these matters is being submitted to the Physical Review.
Prognostic factors of chronic graft‐versus‐host disease after allogeneic blood stem‐cell transplantation (2005)

Allogeneic hematopoietic stem cells in peripheral blood transplantation (alloPBSCT) or bone marrow transplantation (alloBMT) have different biological characteristics which may affect differently prognostic factors for incidence and severity of chronic graft-versus-host disease (cGVHD). To determine the prognostic factors of cGVHD in patients receiving alloPBSCT, data on 87 patients who survived at least 100 days after matched related donor myeloablative transplantation were analyzed. Factors significantly associated with higher incidence of cGVHD after alloPBSCT included CMV-positive donor, acute skin GVHD, and diagnoses other than lymphoma. Factors predictive for poor survival following cGVHD diagnosis included platelet count < 100,000/mm3 and history of acute liver GVHD. Acute liver GVHD and etoposide in the preparative regimen significantly increased risk of death due to cGVHD after alloPBSCT. All alloPBSCT multivariate models were fit to an independent cohort of comparable matched related donor alloBMT patients (n=75). After alloBMT, only acute skin GVHD and diagnoses other than lymphoma retained prognostic significance for predicting cGVHD. Low platelet count was the only variable predictive for poor survival in cGVHD patients after alloBMT. Acute liver GVHD was the only factor that retained prognostic significance for risk of death due to cGVHD after alloBMT. These data suggest there are some cGVHD prognostic factors that may be unique to recipients of alloPBSCT. More studies are needed to determine whether cGVHD prognostic systems should be used interchangeably in patient populations receiving different stem-cell products.

Platelet serotonin transporter:ex vivo monitoring of kinetic parameters in the individiual rat (1999)

We have devloped a method permitting full kinetic measurement of serotonin transporter (5-hydroxytryptamine transporter, 5HTt) on rat platelets without the need of sacrificing the animal, and so individual monitoring of Km and Vmax over time. Blood sample of 1.0 mL was obtained by jugular venipuncture under light ether narcosis and platelet-rich-plasma (PRP) was prepared by centrifugation in adapted syringes and separated quantitatively. After thorough reassessment of methodological parameters, measurements were performed as follows: aliquots of 50 μL of PRP were incubated with 6 concentrations of 14C-5HT (0.07-1.00 μM, final) during 30 seconds at 37°C; uptake of serotonin was terminated by vacuum filtration at 550 mmHg; blank values were obtained by repeating the procedure at 0°C. Mean values from a group of 31 animals were 2.86 ± 0.41 nmol 5HT/mg platelet protein/min for Vmax and 0.160 ± 0.024 μM for Km (M±SD). The described method, enabling the repetition of measurements in individual animal, makes possible the performance of longitudinal (patho)physiological studies on 5HT transporter in the rat.
Regulation of lck degradation and refractory state in CD8+cytotoxic T lymphocytes (2005)

After specific activation, CD8 + cytotoxic T lymphocytes (CTLs) enter a refractory state termed activation-induced nonresponsiveness (AINR) that is characterized by the inability of T cells to respond to a secondary stimulus. Here, we show that T cell receptor triggering results in rapid degradation of the src-family protein kinase lck through a mechanism that is proteasome- and lysosome-independent, sensitive to cysteine protease inhibitors, and distinct from the pathways involved in degradation of ZAP-70 kinase or ζ-chain of the CD3 complex. Pharmacologic blockade of lck degradation, as well as transfection of refractory cells with an lck expression vector, increased responsiveness of CTLs to repeated antigenic challenge. The development or maintenance of AINR was not affected by exogenously added IL-2, whereas IL-15 or IFN-α restored both lck expression and responsiveness of preactivated CTLs. Our results suggest that lck degradation plays an important role in the development of AINR in human CTLs and that this condition can be reverted by pharmacologic agents or lymphokines that prevent lck degradation or induce its expression.

Purification and Properties of Acid Carboxypeptidase II from Aspergillus oryzae (1972)

Acid carboxypeptidase II from Aspergillas oryzae was purified from the rivanol nonprecipitated fraction. The purified enzyme was homogeneous on polyacrylamide gel disc electrophoresis. The optimum activity of the enzyme lay at pH 3.0 for carbobenzoxy-L-glutamyl-L-tyrosine. The enzyme was inhibited by diisopropylphosphorofluoridate and SH reagents such as p-chloromercuribenzoate and monoiodoacetate, but not by such metal chelating agents as ethylenediaminetetraacetate, α, α'-dipyridyl and o-phenanthroline. The molecular weight of the enzyme was estimated to be about 105, 000.
