An inrush current reduction technique for the line-interactive uninterruptible power supply systems (2013)

Numerous sensitive loads of commercial, industrial and domestic use depend upon an uninterruptible power supply (UPS) system to ensure uninterrupted, reliable, and high quality power during outages as well as over voltage and under voltage conditions to maintain healthy operation. In case of a power failure or other disturbance, a UPS system generally takes over the load within a few milliseconds in order to supply continuous power to the load and avoid any interruption. However, due to the magnetic saturation of the load transformer, this transition of load can cause significant inrush current generation. The generation of inrush current can cause the reduced line voltage and activate the over current protection of a UPS system. This paper proposes an inrush current reduction technique by supplying the rated current to the load and energizing the secondary of the transformer to its rated magnetizing current through a current regulated voltage source inverter after connecting it to the secondary of transformer. The possibility of the generation of inrush current is almost completely eliminated during all possible loading and transient conditions. Simulations have been performed by using simulink to validate the proposed inrush current reduction technique. ?? 2013 IEEE.
OLED-on-CMOS integration for augmented-reality systems (2008)

Several fields of application are increasingly using augmented-reality to enhance their performance, e.g., maintenance, manufacturing and security,. OLED-on-CMOS technology provides significant benefits to the realization of compact and lightweight augmented-reality systems. This paper describes the integration of highly-efficient, low-voltage organic light emitting diodes (OLEDs) and photodiodes on a CMOS-substrate to combine display and camera functionality (OLEDCam) in a single optical microsystem device. The optical engineering aspects to project images into the human eye and capture the user's point of gaze at the same time will be discussed. To support human-computer interaction we present a system concept to integrate eye-tracking capability into head-mounted displays (HMDs) using an OLEDCam. The portable control electronic and OLEDCam prototypes are presented. Based on results obtained from the first OLEDCam samples we examine the challenges and identify specifications in an augmented-reality system design. Finally, we introduce possible applications using OLED-on-CMOS for augmented-reality systems.
Authentication using Smart Contracts in a Blockchain (2018)

A challenge with user authentication using passwords is to ensure that they are kept
in a safe storage. The most commonly used approach to achieve this is to have a
centralized storage with high security measurements but this puts this storage at
high risk of being targeted in an attack. We propose an authentication method
using a Smart Contracts in a blockchain as a public key storage to solve this issue.
This enables same security standards as traditional authentication, with increased
availability and usability. Our results show that this method of authentication is a
viable alternative to existing ones.
A homomorphic filtering method for imaging strongly scattering penetrable objects (1995)

This paper describes a new method for determining the structure of strongly scattering penetrable objects having permittivity fluctuations with scales comparable to the illuminating wavelength. We are concerned with the case when small wavelength or weakly scattering approximations, such as the Born or distorted wave Born approximations, or slowly varying approximations such as the Rytov approximation, are not valid. The problem is formulated as one of recovering, in principle, a quantitative image of the object's permittivity distribution function from a set of perturbed images. Each perturbed image is obtained by backpropagating the scattered field measured around the object for different illumination directions. These backpropagated images are filtered in the differential cepstral domain to recover the object permittivity distribution, and we show reconstructions from both simulated and real microwave scattered data.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
The two hit hypothesis in the antiphospholipid syndrome: acute ischaemic heart involvement after valvular replacement despite anticoagulation in a patient with secondary APS (2003)

A patient with the antiphospholipid syndrome (APS), in whom a nonfatal myocardial infarction ensued after valvular heart replacement despite anticoagulation, is described. The report further stresses the role of concomitant risk co-factors in inducing thrombotic events and points out that cardiosurgery might represent a potential major risk for myocardial ischaemic damage in APS.
Hydrogen sulfide inhibits aortic valve calcification in heart via regulating RUNX2 by NF-κB, a link between inflammation and mineralization (2020)

Hydrogen sulfide inhibits inflammation and calcification of aortic valve. Our study suggests that the regulation of Runx2 by hydrogen sulfide (CSE/CBS) occurs via NF-κB establishing a link between inflammation and mineralization in vascular calcification.
Evidence for the Formation of Gas-Phase Inclusion Complexes with Cyclodextrins and Amino Acids (2000)

Experimental and theoretical evidence is provided that indicates the presence of inclusion complexes in the gas phase when cyclodextrin and amino acid mixtures are electrosprayed into a Fourier transform mass spectrometer. A guest exchange reaction that is enantiospecific is used to probe the structure of the gas-phase complex. Chiral selectivity is affected by both the size of the guest and the size of the cavity. These observations are based on a selected number of amino acids with various hosts. The experimental results are supported by molecular dynamics calculations. We further conclude that rather than nonspecific complexes, amino acid−cyclodextrin complexes produced in solution maintain the included structure even in the gas phase.

Identification of Trans-Acting Genes Necessary for Centromere Function in Drosophila melanogaster Using Centromere-Defective Minichromosomes (1997)

Deletions in the Drosophila minichromosome Dp1187 were used to investigate the genetic interactions of trans-acting genes with the centromere. Mutations in several genes known to have a role in chromosome inheritance were shown to have dominant effects on the stability of minichromosomes with partially defective centromeres. Heterozygous mutations in the ncd and klp3A kinesin-like protein genes strongly reduced the transmission of minichromosomes missing portions of the genetically defined centromere but had little effect on the transmission of minichromosomes with intact centromeres. Using this approach, ncd and klp3A were shown to require only the centromeric region of the chromosome for their roles in chromosome segregation. Increased gene dosage also affected minichromosome transmission and was used to demonstrate that the nod kinesin-like protein gene interacts genetically with the centro mere, in addition to interacting with extracentromeric regions as demonstrated previously. The results presented in this study strongly suggest that dominant genetic interactions between mutations and centromere-defective minichromosomes could be used effectively to identify novel genes necessary for centromere function.
The hit array: an analysis formalism for multiple access frequency hop coding (1991)

A formalism is presented for the analysis of general frequency hop waveforms, such as those suitable for use in coherent active radar and sonar echolocation systems as well as multiple-access spread-spectrum communications. This formalism is based on the concept of coincidence, or 'hit', between two frequency hopping patterns. The collection of all possible hits, together with their locations, is recorded in time-frequency space, which produces the high array associated with the two patterns considered. If the code length is sufficiently small with respect to the time-bandwidth product chosen, the hit array can be viewed as a digital representation of the corresponding ambiguity function. Salient properties of the hit array formalism are derived, including simple relationships between hit arrays resulting from basic symmetry-preserving transformations. These properties make it possible to predict the performance of a given set of frequency hop waveforms directly from the associated set of frequency hopping patterns.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Modeling Actions through State Changes (2013)

In this paper we present a model of action based on the change in the state of the environment. Many actions involve similar dynamics and hand-object relationships, but differ in their purpose and meaning. The key to differentiating these actions is the ability to identify how they change the state of objects and materials in the environment. We propose a weakly supervised method for learning the object and material states that are necessary for recognizing daily actions. Once these state detectors are learned, we can apply them to input videos and pool their outputs to detect actions. We further demonstrate that our method can be used to segment discrete actions from a continuous video of an activity. Our results outperform state-of-the-art action recognition and activity segmentation results.

Solution Properties of Chitin in Alkali (2004)

The solution properties of alpha-chitin dissolved in 2.77 M NaOH are discussed. Chitin samples in the weight-average molecular weight range 0.1 x 10(6) g/mol to 1.2 x 10(6) g/mol were prepared by heterogeneous acid hydrolysis of chitin. Dilute solution properties were measured by viscometry and light scattering. From dynamic light scattering data, relative similar size distributions of the chitin samples were obtained, except for the most degraded sample, which contained aggregates. Second virial coefficients in the range 1 to 2 x 10(-3) mL.mol.g(-2) indicated that 2.77 M NaOH is a good solvent to chitin. The Mark-Houwink-Sakurada equation and the relationship between the z-average radius of gyration (Rg) and the weight-average molecular weight (Mw) were determined to be [eta] = 0.10Mw0.68 (mL.g(-1)) and Rg = 0.17Mw0.46 (nm), respectively, suggesting a random-coil structure for the chitin molecules in alkali conditions. These random-coil structures have Kuhn lengths in the range 23-26 nm.
Acquired pure red cell aplasia associated with malignant lymphomas: A nationwide cohort study in Japan for the PRCA Collaborative Study Group (2008)

Pure red cell aplasia (PRCA) has been reported in association with lymphoma as one of the autoimmune diseases seen during the course of lymphoid malignancies. However, the relation of PRCA with the underlying lymphomas remains unclear. The aim of this study was to clarify the histologic subtypes of lymphomas, the chronological sequence of anemia and lymphoma, and the response to treatment. We conducted a nationwide survey in Japan. From a cohort of 185 PRCA patients, 8 patients with lymphoma were evaluated. Histologic subtypes varied and the lymphoma was of the B-cell type in four cases and of the T-cell type in four. Four patients simultaneously developed PRCA and lymphoma. Three patients developed PRCA following lymphoma, two of whom developed anemia during remission of lymphoma. PRCA preceded lymphoma in one patient. Effective chemotherapy was associated with remission of anemia in concurrent lymphoma and PRCA. Overall, anemia responded to chemotherapy and/or immunosuppressive therapy in seven patients. In four responding patients, PRCA remained in durable remission without maintenance immunosuppressive therapy, which is different from a recurrent feature of idiopathic PRCA. We suggest that the mechanism of lymphoma-associated PRCA is heterogeneous and that durable maintenance-free remission of anemia can be obtained in some patients.
Structure of Electrodeposited Cobalt (2002)

The structure of cobalt formed by electrodeposition and the influence of the pH of the plating solution and the cathode potential was studied by potentiodynamic measurements and X-ray diffraction. It was found that the level of overpotential significantly affects the structure of the formed cobalt. When electrodeposition is performed far from equilibrium conditions, i.e., at a high overpotential, face-centered cubic (fcc) cobalt is deposited while at low overpotential hexagonal close packed Co is formed with a lower rate of hydrogen evolution. A higher overpotential is needed in a neutral compared to acidic solution in order to enhance the evolution of hydrogen that is required for the formation of fcc cobalt. © 2002 The Electrochemical Society.

[In vitro studies of clonable human B lymphocytes]. (1983)

A recently developed micro agar culture system has been optimized for the in vitro growth of human B-lymphocytes. Enriched B-lymphocytes from the peripheral blood of normal individuals were suspended in an agar layer, above which a liquid overlayer containing 20% PHA-LCM, 2-ME and Prot A or LPS as stimulants was added. Two morphologically distinguishable colony types were observed using this culture technique: diffusely proliferating colonies (Type I) were found within the agar layer, and round, compact colonies (Type II) appeared to leave the agar layer and continue growth in the liquid overlayer. For both colony types a linear relationship was demonstrated between the number of seeded cells and the number of formed colonies. The appearance of the two colony types in vitro was not concurrent, and they exhibited differing sensitivity to mitogen concentration and to the type of serum used as additive to the culture medium. The implications of clonal in vitro cultivation of lymphocytes, both normal and pathological, are discussed.
The Application of Long Short-Term Memory(LSTM) Method on Displacement Prediction of Multifactor-Induced Landslides (2019)

Landslides induced by rainfall frequently happen in South-western China where steep slopes, loess plateau occur. Thus, it is empirical to build the early warning system to evaluate the potential of landslide hazards. However, current researches mostly focus the static model on displacement prediction. The landslide is a nonlinear hazard characterized by dynamic features. Therefore, the dynamic model should be investigated to more precisely predict the displacement associated with the landslide. In this paper, Laowuji Landslide is adopted to investigate the dynamic failure mode. The displacement of the Laowuji landslide contains the trend and periodic component. The trend component is predicted by the empirical mode decomposition and the periodic component is predicted by the long short-term memory (LSTM) method. Model's input includes multiple factors of geological conditions, rainfall intensity, and human activities. The measured data and the predicted data show good consistency. In addition, the predicted results of the periodic component show that the performance of the LSTM has good characteristics of dynamic feature. Compared with a traditional mechanical model, the hybrid model is more powerful to predict the landslide displacement triggered by multiplying factors.

MuSK is required for anchoring acetylcholinesterase at the neuromuscular junction (2004)

At the neuromuscular junction, acetylcholinesterase (AChE) is mainly present as asymmetric forms in which tetramers of catalytic subunits are associated to a specific collagen, collagen Q (ColQ). The accumulation of the enzyme in the synaptic basal lamina strictly relies on ColQ. This has been shown to be mediated by interaction between ColQ and perlecan, which itself binds dystroglycan. Here, using transfected mutants of ColQ in a ColQ-deficient muscle cell line or COS-7 cells, we report that ColQ clusterizes through a more complex mechanism. This process requires two heparin-binding sites contained in the collagen domain as well as the COOH terminus of ColQ. Cross-linking and immunoprecipitation experiments in Torpedo postsynaptic membranes together with transfection experiments with muscle-specific kinase (MuSK) constructs in MuSK-deficient myotubes or COS-7 cells provide the first evidence that ColQ binds MuSK. Together, our data suggest that a ternary complex containing ColQ, perlecan, and MuSK is required for AChE clustering and support the notion that MuSK dictates AChE synaptic localization at the neuromuscular junction.
One-Step Ahead Prediction of Angular Momentum about the Contact Point for Control of Bipedal Locomotion: Validation in a LIP-inspired Controller (2021)

Ultimately, feedback control is about making adjustments using current state information in order to meet an objective in the future. In the control of bipedal locomotion, linear velocity of the center of mass has been widely accepted as the primary variable around which feedback control objectives are formulated. In this paper, we argue that it is easier to predict the one-step ahead evolution of angular momentum about the contact point than it is to make a similar prediction for linear velocity, and hence it provides a superior quantity for feedback control. So as not to confuse the benefits of predicting angular momentum with any other control design decisions, we reformulate the standard LIP model in terms of angular momentum and show how to regulate swing foot touchdown position at the end of the current step so as to meet an angular momentum objective at the end of the next step. We implement the resulting feedback controller on the 20 degree-of-freedom bipedal robot, Cassie Blue, where each leg accounts for nearly one-third of the robot&#x2019;s total mass of 32 Kg. Under this controller, the robot achieves fast walking, rapid turning while walking, large disturbance rejection, and locomotion on rough terrain.
N-Tosyl-l-phenylalanine Chloromethyl Ketone Inhibits NF-κB Activation by Blocking Specific Cysteine Residues of IκB Kinase β and p65/RelA (2009)

N-Tosyl-L-phenylalanine chloromethyl ketone (TPCK), a serine/cysteine protease inhibitor, has been reported to inhibit expression of inflammatory mediators by blocking nuclear factor-kappaB (NF-kappaB) activation. We examined the effect of TPCK on the NF-kappaB activation pathway in HeLa cells by measuring the activity of IkappaB kinase (IKK) and p65/RelA-DNA binding. TPCK inhibited tumor necrosis factor-alpha-induced IKK activation and directly blocked IKK activity in vitro. TPCK-induced inhibition of NF-kappaB and IKK activation was abrogated by addition of the thiol-reducing agent dithiothreitol, suggesting that the effect of TPCK occurred through modification of a thiol group in IKK. Consistent with this, an IKKbeta mutant in which Cys-179 was substituted with alanine was not more susceptible to TPCK. Our result also showed that TPCK inhibits the DNA binding of transiently expressed p65/RelA in HeLa cells. Inhibition of p65/RelA-DNA binding was recovered in the presence of dithiothreitol, and substitution of Cys-38 with Ser in p65/RelA rendered the protein resistant to inhibition by TPCK. Mass spectrometry analysis of IKKbeta and p65/RelA isolated from cells treated with TPCK by UPLC-ESI-Q-TOF tandem MS revealed the labeling of Cys-179 of IKKbeta and Cys-38 of p65/RelA with a tosylphenylalanylmethyl group. These results suggest that TPCK inhibits NF-kappaB activation by directly modifying thiol groups on two different targets: Cys-179 of IKKbeta and Cys-38 of p65/RelA.
Tissue Visualization Using X-Ray Dark-Field Imaging towards Pathological Goal (2013)

In XDFI (x-ray dark-field imaging) LAA (Laue-case angle analyzer) simultaneously provides two x-ray images; one corresponds to a FD forward diffracted beam and a separate D diffracted beam. When this is applied to biomedical specimens x-ray images are very high contrast and very high spatial resolution. We constructed XDFI system at the vertical wiggler beamline BL-14C in KEK Photon Factory and performed imaging experiment of breast tissues and an excised human femoral artery. In this paper, we discuss a tissue visualization and pathological goal using 2D, 3D-CT and 2.5D image (tomosynthesis) with XDFI.
