TUNABLE PERIODIC MICROSTRIP STRUCTURE ON GAAS WAFER (2009)

A one dimensional tunable periodic structure in microstip technology on gallium arsenide (GaAs) substrate is numerically investigated. The unit cell contains a number of patches positioned between the ground plane and the microstrip line. The patches, representing reactive loads, can be selectively short-circuited by externally-controlled FET switches integrated in the hosting substrate. The possibility of controlling the position of the band-gap, and implicitly the value of the efiective dielectric constant along the line, for difierent combinations of the switches is demonstrated.
Fourier series expansion for nonlinear Hamiltonian oscillators (2010)

The problem of nonlinear Hamiltonian oscillators is one of the classical questions in physics. When an analytic solution is not possible, one can resort to obtaining a numerical solution or using perturbation theory around the linear problem. We apply the Fourier series expansion to find approximate solutions to the oscillator position as a function of time as well as the period-amplitude relationship. We compare our results with other recent approaches such as variational methods or heuristic approximations, in particular the Ren-He's method. Based on its application to the Duffing oscillator, the nonlinear pendulum and the eardrum equation, it is shown that the Fourier series expansion method is the most accurate.

A J-band Transceiver MMIC with image rejection (2000)

This paper describes a J-band (15 GHz) transceiver MMIC with image rejection that has been designed for RADAR T/R module applications. The MMIC consists of a switched attenuator, an LNA, a Transmit/Receive switch, an image rejection mixer and a local oscillator buffer amplifier. The size of the MMIC is 6.48 mm by 4.47 mm. In receive mode the MMIC has a conversion gain in excess of 10 dB with less than 1 dB of ripple and noise figure less than 4 dB across a 10 GHz to 16.5 GHz band. The Input P1dB is -13 dBm. In transmit mode the conversion gain is -12 dB with an input P1dB of +15 dBm. The Transceiver MMIC was fabricated using the GMMT, 0.25 μm, H40 pHEMT process. This is believed to be the first integrated transceiver MMIC designed specifically for this frequency band.
Statistics of cell loss and its application for forward error recovery in ATM network (2003)

A virtual path (VP) is modeled as a tandem queuing network. The statistics of cell loss due to cell level congestion are studied. The focus is on a designated traffic stream as it passes through an asynchronous transfer mode (ATM) network along a VP. The performance of a VP with forward error recovery coding scheme and the design of suitable coding schemes utilizing cell loss statistics are discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Classification and Forecasting for Enterprise Data (2018)

There is an increasing interest in classification and forecasting for enterprise data. Besides many similarity or dissimilarity measures, Support Vector Machines have also been used for time series classification. We classify the industry data with autocorrelation function-distance, an automatic adaptive dissimilarity index and Support Vector Machines respectively. Then we make forecasting for different class. Every class is fitted with particular season model according to Akaike Information Criteria. The orders of the particular model are estimated. A comparative study is presented. It is proposed that an automatic adaptive dissimilarity index outperforms autocorrelation function distance and Support Vector Machines.
Fractional giant Shapiro steps and spatially correlated phase motion in 2D Josephson arrays (1990)

We have applied radio-frequency signals to 1000 by 1000 arrays of Josephson junctions and observed giant Shapiro steps at voltages 1000 times that expected for a single junction. When a perpendicular magnetic field is applied, fractional giant steps appear at voltages directly related to the number of flux quanta per unit cell. A phenomenological model is proposed that utilizes the spatial arrangement of the vortices in a superlattice relative to the underlying array to explain these novel steps.
Quantum convolutional error-correcting codes (1998)

I report two general methods to construct quantum convolutional codes for $N$-state quantum systems. Using these general methods, I construct a quantum convolutional code of rate 1/4, which can correct one quantum error for every eight consecutive quantum registers.
Disassembly Path Planning for Complex Articulated Objects (2008)

<para xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> Sampling-based path planning algorithms are powerful tools for computing constrained disassembly motions. This paper presents a variant of the Rapidly-exploring Random Tree (RRT) algorithm particularly devised for the disassembly of objects with articulated parts. Configuration parameters generally play two different roles in this type of problems: some of them are essential for the disassembly task, while others only need to move if they hinder the progress of the disassembly process. The proposed method is based on such a partition of the configuration parameters. Results show a remarkable performance improvement as compared to standard path planning techniques. The paper also shows practical applications of the presented algorithm in robotics and structural bioinformatics. </para>
Basic fibroblast growth factor stimulates myelopoiesis in long-term human bone marrow cultures (1991)

We previously showed that basic fibroblast growth factor (bFGF) is a potent mitogen for human bone marrow (BM) stromal cells and significantly delays their senescence. In the present study, we demonstrated that low concentrations of bFGF (0.2 to 2 ng/mL) enhance myelopoiesis in long-term human BM culture. Addition of bFGF to long- term BM cultures resulted in an increase in (a) the number of nonadherent cells (sixfold), particularly those of the neutrophil granulocyte series; (b) the number of nonadherent granulocyte colony- stimulating factor (G-CSF)- and granulocyte-macrophage colony- stimulating factor (GM-CSF)-responsive progenitor cells; (c) the number of adherent foci of hematopoietic cells (10-fold); and (d) the number of progenitor cells in the adherent stromal cell layer. These effects were not noted with higher concentrations of bFGF (20 ng/mL). Thus, low concentrations of bFGF effectively augment myelopoiesis in human long- term BM cultures, and bFGF may therefore be a regulator of the hematopoietic system in vitro and in vivo.
Ten-year results from the National Surgical Adjuvant Breast and Bowel Project (NSABP) clinical trial evaluating the use of L-phenylalanine mustard (L-PAM) in the management of primary breast cancer. (1986)

Between 1972 and 1974, patients were entered into a National Surgical Adjuvant Breast and Bowel Project (NSABP) trial to evaluate L-phenylalanine mustard (L-PAM) as an adjuvant to mastectomy in patients with primary breast cancer and pathologically positive axillary nodes. Overall, findings through 10 years of observation indicate an 8% difference in disease-free survival (DFS) (P = .06) and a 5% difference in survival (P = .4). Women less than or equal to 49 years of age who received L-PAM demonstrate a significant (P = .03) prolongation of DFS and a significant (P = .05) survival benefit compared with those who received a placebo. There is a 37% reduction in their mortality and a cumulative odds of survival of 1.67. In that age group, both those with one to three and greater than or equal to 4 positive nodes benefited, but the advantage was greater when there were fewer positive nodes. There was a significant (P = .009) reduction in mortality (64%) and a cumulative odds of survival of 3.25 in patients less than or equal to 49 years old with one to three positive nodes. No advantage from L-PAM was observed in patients greater than or equal to 50 years old. When L-PAM response is related to nuclear grade, a marker of tumor differentiation, there is a highly significant improvement in DFS (less than .001), distant DFS (.001), and survival (.004) through 10 years of observation for all patients with tumors classified as nuclear grade poor (poorly differentiated), regardless of age and nodal status. Mortality was reduced by 32% and the cumulative odds of survival was 2.10 at 10 years. Of singular importance is the observation of a benefit in those greater than or equal to 50 years of age as well as in those less than or equal to 49 years of age with poorly differentiated tumors. There is a significant (P = .003) survival benefit for those in the older age group with a 37% reduction in mortality, and a cumulative odds of survival of 2.75. Patients in both age groups with well-differentiated tumors demonstrated no benefit from L-PAM. Those who are older seem to do less well following chemotherapy. We conclude that tumor differentiation is a better discriminant of response to chemotherapy than is age, and that both younger and older women are responsive to adjuvant chemotherapy when they have poorly differentiated tumors.
Soft error rate determination for nanoscale sequential logic (2010)

We analyze the neutron induced soft error rate (SER) by modeling induced error pulse using two parameters, occurrence frequency and probability density function for the pulse width. We extend the analysis to sequential logic and latches and calculate the failures in time (FIT) rate. The analysis is developed for the available background neutron flux data, which is experimentally determined. This, along with the device characteristics, gives the induced pulse parameters. A gate-level algorithm propagates the pulse parameters through logic gates. This algorithm correctly models the logic masking of error pulses. We introduce the concept of latching window that accurately models the temporal masking by sequential elements and present an algorithm for SER analysis of sequential logic.
Controlling the cytokine storm in severe bacterial diarrhoea with an oral <scp>T</scp>oll‐like receptor 4 antagonist (2015)

Shigella dysenteriae causes the most severe of all infectious diarrhoeas and colitis. We infected rhesus macaques orally and also treated them orally with a small and non-absorbable polypropyletherimine dendrimer glucosamine that is a Toll-like receptor-4 (TLR4) antagonist. Antibiotics were not given for this life-threatening infection. Six days later, the clinical score for diarrhoea, mucus and blood was 54% lower, colon interleukin-8 and interleukin-6 were both 77% lower, and colon neutrophil infiltration was 75% less. Strikingly, vasculitis did not occur and tissue fibrin thrombi were reduced by 67%. There was no clinical toxicity or adverse effect of dendrimer glucosamine on systemic immunity. This is the first report in non-human primates of the therapeutic efficacy of a small and orally bioavailable TLR antagonist in severe infection. Our results show that an oral TLR4 antagonist can enable controlled resolution of the infection-related-inflammatory response and can also prevent neutrophil-mediated gut wall necrosis in severe infectious diarrhoeas.
Implantable Graphene-based Neural Electrode Interfaces for Electrophysiology and Neurochemistry in In Vivo Hyperacute Stroke Model (2015)

Implantable microelectrode arrays have attracted considerable interest due to their high temporal and spatial resolution recording of neuronal activity in tissues. We herein presented an implantable multichannel neural probe with multiple real-time monitoring of neural-chemical and neural-electrical signals by a nonenzymatic neural-chemical interface, which was designed by creating the newly developed reduced graphene oxide-gold oxide (rGO/Au2O3) nanocomposite electrode. The modified electrode on the neural probe was prepared by a facile one-step cyclic voltammetry (CV) electrochemical method with simultaneous occurrence of gold oxidation and GOs reduction to induce the intimate attachment by electrostatic interaction using chloride ions (Cl(-)). The rGO/Au2O3-modified electrode at a low deposition scan rate of 10 mVs(-1) displayed significantly improved electrocatalytic activity due to large active areas and well-dispersive attached rGO sheets. The in vitro amperometric response to H2O2 demonstrated a fast response of less than 5 s and a very low detection limit of 0.63 μM. In in vivo hyperacute stroke model, the concentration of H2O2 was measured as 100.48 ± 4.52 μM for rGO/Au2O3 electrode within 1 h photothrombotic stroke, which was much higher than that (71.92 μM ± 2.52 μM) for noncoated electrode via in vitro calibration. Simultaneously, the somatosensory-evoked potentials (SSEPs) test provided reliable and precise validation for detecting functional changes of neuronal activities. This newly developed implantable probe with localized rGO/Au2O3 nanocomposite electrode can serve as a rapid and reliable sensing platform for practical H2O2 detection in the brain or for other neural-chemical molecules in vivo.
A method of text event detection and image enhancement based on aerial video (2009)

In order to extract numbers from an aerial video, an improved algorithm of the text event detection is presented in this paper. This method intercepts key frames using the way of comparison between frame difference and the dynamic threshold. In this way, it can avoid unnecessary trouble made by dealing with the video frame by frame. Results show that this method can save much computing time as well as improve operating efficiency. Besides, a new method of de-noising for binary image is proposed during image preprocessing. For the sum of the column pixel of noise is much less than the concerned area, we can successfully remove the noise pixel and pave the way for the future steps such as character division or number recognition. As the results shown, this method is especially suitable for processing poor quality images.

Radiolabeled Atrial Natriuretic Peptide and Somatostatin for in Vivo Imaging of Receptors (1993)

For many years peptides and proteins labeled with Iodine-125 on tyrosine residues have been standard tools of biochemistry for the in vitro mapping of receptors. Such methods provide microscopic information on a cellular level but little overall information about the in vivo biodistribution of the receptors and their dynamic relationship with their endogenous ligands. The gathering of this in vivo information by techniques such as Nuclear Imaging has been limited by the rapid catabolism of radiolabeled peptides in circulation. This is not as a result of labeling but is due to the extremely short half-life of peptides in vivo. The normal fate of peptides in circulation is to be partitioned between a large pool of low affinity non-specific peptidases and a small quantity of specific, high affinity receptors. Under such circumstances the labeled peptide will preferentially bind to the high affinity receptors but injection of amounts greater than the capacity of the receptors will cause overflow into the non-specific peptidase pool, with corresponding loss of information. Furthermore, it is important that receptor occupancy by the labeled peptide be limited, perhaps to less than 10% of receptor mass, in order that the ligand/receptor interactions observed are true tracer phenomena and not due to perturbation of the natural equilibrium by the injected material.
Interferon-γ Inhibits 1,25-Dihydroxyvitamin D<sub>3</sub>- Stimulated Synthesis of Bone GLA Protein in Rat Osteosarcoma Cells by a Pretranslational Mechanism* (1990)

Interferon-gamma (IFN) is produced by lymphocytes in areas of inflammation and connective tissue destruction. IFN inhibits collagen and DNA synthesis in cultured rat long bones and osteoblastic ROS 17/2.8 cells, suggesting that the periarticular loss of bone that occurs in inflammatory joint diseases may be due to IFN inhibition of bone formation. Since serum levels of bone gla protein (BGP) have been correlated with the bone formation rate, we studied the effect of IFN on production of this osteoblast-specific protein and steady state BGP messenger RNA (mRNA) levels in ROS 17/2.8 cells. RIA of BGP was done using an antibody raised against rat BGP peptide. BGP synthesis was stimulated with 10(-8) M 1,25-dihydroxyvitamin D3 24 h before and continuously after addition of recombinant rat IFN. IFN (100 U/ml) inhibited BGP secretion 52%, 78%, and 70% in the first, second, and third 24 h periods after IFN treatment, compared to control cells cultured with 1,25-dihydroxyvitamin D3 alone. The ED50 for IFN inhibition of BGP production was 3.3 U/ml (0.29 nM). Pulse labeling with [14C]leucine or [3H]proline during the last 4 h of culture revealed that IFN (3-100 U/ml) did not inhibit total protein secretion into the medium. The percent inhibition of BGP production by IFN was independent of media serum concentration or cell density. IFN (100 U/ml) decreased the steady state level of BGP mRNA as measured by Northern analysis using an oligomeric probe for rat BGP. The decrease in hybridization signal for BGP mRNA was detectable by 1 h after IFN exposure and continued to decline at 6 and 24 h. Treatment with cycloheximide (5 micrograms/ml) blocked the inhibitory effect of IFN on steady state levels of BGP mRNA. These results suggest that IFN may inhibit bone formation by selective inhibition of osteoblast matrix protein production. The mechanism of IFN inhibition of BGP production is, at least in part, pretranslational.
Association Between Soluble CD14 in the Aqueous Humor and Hyperreflective Foci on Optical Coherence Tomography in Patients With Diabetic Macular Edema (2018)

DME patients with diffuse edema exhibit higher sCD14 levels in the AH and more HF in the inner retina than patients with focal edema, indicating severe inflammation. The strong correlation between sCD14 and HF in the inner retina suggests that the HF observed on SD-OCT may be due to activated microglia in DME.
Normalized Compression Distance of Multisets with Applications (2014)

Pairwise normalized compression distance (NCD) is a parameter-free, feature-free, alignment-free, similarity metric based on compression. We propose an NCD of multisets that is also metric. Previously, attempts to obtain such an NCD failed. For classification purposes it is superior to the pairwise NCD in accuracy and implementation complexity. We cover the entire trajectory from theoretical underpinning to feasible practice. It is applied to biological (stem cell, organelle transport) and OCR classification questions that were earlier treated with the pairwise NCD. With the new method we achieved significantly better results. The theoretic foundation is Kolmogorov complexity.
