Satellite Attitude Determination Based on Pushbroom Image Band Coregistration (2018)

LAPAN-A3/IPB multispectral images have been systematically corrected for both geometric and radiometric distortions by using pre-flight imager calibration data as well as in-orbit satellite metadata such as satellite position and attitude. However in several cases, star tracker sensor as the main attitude sensor, could not provide satellite attitude data as needed, which causes some significant performance degradation of the resulting image correction. This research aims to provide satellite attitude data needed for image correction based on multispectral image captured. The research characterizes the relationship between band coregistration distortion occurs on the image to satellite attitude while imaging. Measurements and data fitting which have been conducted show that satellite attitude while imaging has strong relationship to band coregistration distortion caused. However, the accuracy of satellite attitude calculated from band coregistration distortion has moderate accuracy, for about 3 degree for each satellite axis. Although the accuracy produced can be considered low for other applications, it is good enough to provide attitude data needed for image correction purpose.
Perceiving Heading in the Presence of Moving Objects (1995)

In most models of heading from optic flow a rigid environment is assumed, yet humans often navigate in the presence of independently moving objects. Simple spatial pooling of the flow field would yield systematic heading errors. Alternatively, moving objects could be segmented on the basis of relative motion, dynamic occlusion, or inconsistency with the global flow, and heading determined from the background flow. Displays simulated observer translation toward a frontal random-dot plane, with a 10 deg square moving independently in depth. The path of motion of the object was varied to create a secondary focus of expansion (FOE') 6 deg to the right or left of the actual heading point (FOE), which could bias the perceived heading. There was no effect when the FOE was visible, but when the object moved in front of it, perceived heading was biased toward the FOE' by approximately 1.9 degrees with a transparent object, and approximately 3.4 degrees with an opaque object. The results indicate that scene segmentation does not occur prior to heading estimation, which is consistent with spatial pooling weighted near the FOE. A simple template model based on large-field, center-weighted expansion units accounts for the data. This may actually represent an adaptive solution for navigation with respect to obstacles on the path ahead.
Correlation of plasma protein separation patterns obtained by two‐dimensional polyacrylamide gel electrophoresis and by capillary electrophoresis (1998)

We used three different electrophoretic techniques for the analysis of human plasma proteins: (i) two-dimensional polyacrylamide gel electrophoresis (2-D PAGE), with sodium dodecyl sulfate (SDS) used only in slab gel electrophoresis; (ii) capillary isoelectric focusing (CIEF) with no denaturants; (iii) linear polyacrylamide (LPA)-filled capillary electrophoresis with SDS (SDS-CE). With technique (i), data on isoelectric point and molecular size of plasma proteins can be obtained. Techniques (ii) and (iii) are suited to obtain quantitative information on proteins. The separation principle used in technique (ii) is closely related to that used in the first dimension of technique (i), and that used in technique (iii) related to that in the second dimension of technique (i). Therefore, we could successfully correlate protein separation patterns obtained by 2-D PAGE and those obtained by capillary electrophoresis. The advantages of correlating data obtained by various electrophoretic techniques in the course of constructing a comprehensive database on human plasma proteins are discussed.
Manipulation of Base Excision Repair to Sensitize Ovarian Cancer Cells to Alkylating Agent Temozolomide (2007)

These studies show that although clinical trials in ovarian cancer to determine temozolomide single-agent efficacy are in development, through manipulation of the BER pathway, an increase in response to temozolomide is achieved. The combination of temozolomide plus methoxyamine has potential for second-line therapy for patients who have failed standard platinum plus paclitaxel chemotherapy.

Elf5 is an epithelium‐specific, fibroblast growth factor–sensitive transcription factor in the embryonic lung (2007)

Fibroblast growth factor (FGF) signaling has been shown to be essential for many aspects of normal lung development. To determine epithelial targets of FGF signaling, we cultured embryonic day (E) 11.5 mouse lungs for 24 hr in the presence or absence of the FGF receptor antagonist SU5402, which inhibited branching morphogenesis. Affymetrix gene chip analysis of treated and control epithelia identified several genes regulated by FGF signaling, including Elf5, a member of the Epithelial-specific Ets family of transcription factors. SU5402 reduced Elf5 expression in mesenchyme-free cultures of E12.5 epithelium, demonstrating that the inhibition was direct. In situ hybridization revealed that Elf5 had a dynamic pattern of expression during lung development. We found that expression of Elf5 was induced by FGF7 and FGF10, ligands that primarily bind FGFR2b. To further define the pathways by which FGFs activate Elf5 expression, we cultured E11.5 lung tips in the presence of compounds to inhibit FGF receptors (SU5402), PI3-Kinase/Akt-mediated signaling (LY294002), and MAP Kinase/Erk-mediated signaling (U0126). We found that SU5402 and LY294002 significantly reduced Elf5 expression, whereas U0126 had no effect. LY294002 also reduced Elf5 expression in cultures of purified epithelium. Finally, pAkt was coexpressed with Elf5 in the proximal epithelial airways of E17.5 lungs. These results demonstrate that Elf5 is an FGF-sensitive transcription factor in the lung with a dynamic pattern of expression and that FGF regulation of Elf5 by means of FGFR2b occurs through the PI3-Kinase/Akt pathway.
The Trochlea is Bilinear and Oriented Medially (2003)

Malfunctioning of total knee replacements often is related to patellofemoral problems. Because the trochlea guides the patella during flexion and extension, its geometry has a major influence in patellofemoral problems. There is controversy in the literature: relative to the mechanical axis, some authors have found a laterally oriented trochlea and others have found a medially oriented trochlea. The groove of implanted prosthetic femoral components always has lateral or neutral orientations. The objectives of the current study were to clarify the controversy found in the literature, to determine whether the trochlear orientation is truly linear, and to determine whether the orientation depends on the size of the femur. The trochleae of 100 human femurs were measured using a three-dimensional measurement system. Detailed analysis of the results indicated that the trochlea is best described as bilinear, with the distal half oriented 0.2 degrees +/- 2.8 degrees laterally and the proximal half oriented 4.2 degrees +/- 3.2 degrees medially. Trochlear orientation was not dependent on bone size.
Simultaneous HF and DF laser excited by a ferroelectric ceramic capacitively coupled discharge (1980)

With ferroelectric ceramic, principally BaTiO3 dielectric capacitive coupling electrodes, simultaneous HF and DF pulsed laser action has been obtained as a function of [H2]/([H2]+[D2]) in H2+D2+SF6 mixtures. The laser had a multiline output of 30 μJ for an efficiency of 5.4×10−4 at 120 pps. After 107 pulses there has been no degradation of electrodes or decrease in laser performance. Alternate H-source gases of CH4, C2H6, and C3H8 had lower HF laser output than H2.
Application of differential transformation method to nonlinear q-symmetric damped systems (2015)

In this paper, we first induce the recursive formula of q-symmetric polynomials and prove the product rule of two q-symmetric polynomials at 0.Then differential transformation method can be applied to find approximate solution of nonlinear q-symmetric difference equation. Last but not least, the approximate solutions are also contrasted with the numerical solutions to verify their accuracy. Mathematics Subject Classification: 39A12;44A25;26A33
Active Light Control of the MoS<sub>2</sub> Monolayer Exciton Binding Energy (2015)

Plasmonic excitation of Au nanoparticles deposited on a MoS2 monolayer changes the absorption and photoluminescence characteristics of the material. Hot electrons generated from the Au nanoparticles are transferred into the MoS2 monolayers, resulting in n-doping. The doping effect of plasmonic hot electrons modulates the dielectric permittivity of materials, resulting in a red shift of both the absorption and the photoluminescence spectrum. This spectroscopic tuning was further investigated experimentally by using different Au nanoparticle concentrations, excitation laser wavelengths, and intensities. An analytical model for the photoinduced modulation of the MoS2 dielectric function and its exciton binding energy change is developed and used to estimate the doping density of plasmonic hot electrons. Our approach is important for the development of photonic devices for active control of light by light.
Robust visual odometry for complex urban environments (2008)

This paper describes a new approach for estimating the vehicle motion trajectory in complex urban environments by means of visual odometry. A new strategy for robust feature extraction and data post-processing is developed and tested on-road. Scale-invariant Image Features (SIFT) are used in order to cope with the complexity of urban environments. The obtained results are discussed and compared to previous works. In the prototype system, the ego-motion of the vehicle is computed using a stereo-vision system mounted next to the rear view mirror of the car. Feature points are matched between pairs of frames and linked into 3D trajectories. The distance between estimations is dynamically adapted based on reprojection and estimation errors. Vehicle motion is estimated using the non-linear, photogrametric approach based on RANSAC (RAndom SAmple Consensus). The obvious application of the method is to provide on-board driver assistance in navigation tasks, or to provide a means of autonomously navigating a vehicle. The method has been tested in real traffic conditions without using prior knowledge about the scene or the vehicle motion. An example of how to estimate a vehiclepsilas trajectory is provided along with suggestions for possible further improvement of the proposed odometry algorithm.
New Adipose Tissue Formation by Human Adipose-Derived Stem Cells with Hyaluronic Acid Gel in Immunodeficient Mice (2015)

The efficacy of injected filler could be permanent since the reduction of the volume of the HA gel after bioabsorption could be replaced by new adipose tissue generated by hASCs. This is a promising approach for developing long lasting soft tissue filler.

The renal biopsy remains essential for diagnosing the underlying injury that can affect one or more compartments of the kidney in this unique clinical setting.
Spatiotemporal information deep fusion network with frame attention mechanism for video action recognition (2019)

In the deep learning-based video action recognition, the function of the neural network is to acquire spatial information, motion information, and the associated information of the above two kinds of information over an uneven time span. We propose a network for extracting semantic information of video sequences based on the deep fusion feature of local spatial–temporal information. Convolutional neural networks (CNNs) are used in the network to extract local spatial information and local motion information, respectively. The spatial information is in three-dimensional convolution with the motion information of the corresponding time to obtain local spatial–temporal information at a certain moment. The local spatial–temporal information is then input into the long- and short-time memory (LSTM) to obtain the context relationship of the local spatial–temporal information in the long-time dimension. We add the ability of the regional attention mechanism of video frames in the neural network mechanism for obtaining context. That is, the last layer of convolutional layer spatial information and the first layer of the fully connected layer are, respectively, input into different LSTM networks, and the outputs of the two LSTMs at each time are merged again. This enables a fully connected layer that is rich in categorical information to provide a frame attention mechanism for the spatial information layer. Through the experiments on the three action recognition common experimental datasets UCF101, UCF11, and UCFSports, the spatial–temporal information deep fusion network proposed has a high correct recognition rate in the task of action recognition.
Numerical Earth Models (EET 3) (2008)

In this book the main problems related to the construction of an Earth-Model are presented and discussed. The first three chapters are dedicated to the classical methods that can be used to build numerical models, in particular, the author proposes:– some of the classical modeling techniques used in Computer Aided Design (CAD) to model surfaces and their inadequacy for modeling complex geological objects, in particular:– classical interpolation techniques used to model surfaces;– topological models used to describe the connections between surfaces and volumes;– an overview of geomodeling methods dedicated to the discrete modeling of geological objects, in particular:– the Discrete-Smooth-Interpolation method (DSI);– meshing techniques to model surfaces and grids;– a presentation of the classical ?Shared-Earth-Model? (SEM) paradigm consisting in a Structural-Model (SM) plus a Property-Model (PM): SEM = SM + PM– a discussion concerning the problems raised by the (in) compatibility between the Structural-Model (SM) and the Property-Model (PM).
Ebastine in the Treatment of Allergic Rhinitis and Urticaria: 30 Years of Clinical Studies and Real-World Experience (2019)

Histamine, acting predominantly via the H1-receptor, is an important mediator of the symptoms of allergy. H1-antihistamines, which stabilize the receptor in its inactive form, are the treatment of choice for some chronic allergic conditions. Ebastine is a well-established secondgeneration oral H1-antihistamine that is administered once daily at a dose of 10-20 mg and is available both as a standard tablet and as a fast-dissolving tablet that disintegrates in the mouth. Ebastine has been shown to relieve symptoms in patients with allergic rhinitis or urticaria in multiple clinical trials. In addition to its antihistamine effects, the drug has modulating effects on the allergic inflammatory process, thus potentially explaining its beneficial effect on nasal obstruction in some patients. Ebastine is generally well tolerated at recommended doses and is one of the lowest-risk antihistamines with respect to adverse cognitive/psychomotor effects, as confirmed by decades of pharmacovigilance. New long-term data confirm its efficacy and tolerability during up to 1 year of treatment in patients with chronic urticaria.
Feature predictive vector quantization of multispectral images (1992)

A compression method for multispectral data sets is proposed where a small subset of image bands is initially vector quantized. The remaining bands are predicted from the quantized images. Two different types of predictors are examined, an affine predictor and a new nonlinear predictor. The residual (error) images are encoded at a second stage based on the magnitude of the errors. This scheme simultaneously exploits both spatial and spectral correlation inherent in multispectral images. Simulation results on an image set from the Thematic Mapper with seven spectral bands provide a comparison of the affine predictor with the nonlinear predictor. It is shown that the nonlinear predictor provides significantly improved performance compared to the affine predictor. Image compression ratios between 15 and 25 are achieved with remarkably good image quality.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Sinusoidal SBPSK Modulation Waveform for UHF SATCOM Channels with Improved Adjacent Channel Emissions (2007)

It has long been established that all transmissions over US-owned UHF SATCOM channels be adjacent channel emissions (ACE) compliant according to the MIL-STD-188-181 series of standards. 50% Shaped Binary Phase Shift Keying (SBPSK) and 50% SOQPSK are specifically called out for use as the modulation formats of choice for the 5 kHz (narrowband) and 25 kHz (wideband) channels. The ACE requirements are levied in terms of relative RF power spilling over into the adjacent channels above and below the main transmitting frequency. The SOQPSK modulation waveform offers outstanding side lobe suppression such that the ACE requirements are readily met with the standard SOQPSK waveform. The 50% SBPSK waveform, however, has very little ACE margin in the first two 5 kHz offset channels, nor for 9600 bps in the first two 25 kHz offset channels. Methods like the piece-wise-linear approach have been introduced to improve the ACE performance for the 5 kHz channels. This paper introduces a sinusoidal (non-linear) phase shaping method that offers good ACE performance, good bit error rate performance and a relatively easy hardware implementation. This nonlinear phase transition shaping method offers superior ACE suppression with little or no additional modem implementation loss as compared to a coherent BPSK demodulator. The phase transitions from zero to π are achieved by using a sinusoidal function with no phase discontinuity in the transition region. The transition time can vary from zero to the full baud time, achieving a 0 % to 100 % shaping as defined in the SBPSK case.
The Energy Landscapes and Motions of Proteins (1991)

Recent experiments, advances in theory, and analogies to other complex systems such as glasses and spin glasses yield insight into protein dynamics. The basis of the understanding is the observation that the energy landscape is complex: Proteins can assume a large number of nearly isoenergetic conformations (conformational substates). The concepts that emerge from studies of the conformational substates and the motions between them permit a quantitative discussion of one simple reaction, the binding of small ligands such as carbon monoxide to myoglobin.
Dopamine Induces Apoptosis through an Oxidation-involved SAPK/JNK Activation Pathway (1998)

Dopamine (DA) is a neurotransmitter, but it also exerts a neurotoxic effect under certain pathological conditions, including age-related neurodegeneration such as Parkinson's disease. By using both the 293 cell line and primary neonatal rat postmitotic striatal neuron cultures, we show here that DA induces apoptosis in a time- and concentration-dependent manner. Concomitant with the apoptosis, DA activates the JNK pathway, including increases in JNK activity, phosphorylation of c-Jun, and subsequent increase in c-Jun protein. This DA-induced JNK activation precedes apoptosis and is persistently sustained during the process of apoptosis. Transient expression of a dominant negative mutant SEK1(Lys --> Arg), an upstream kinase of JNK, prevents both DA-induced JNK activation and apoptosis. A dominant negative c-Jun mutant FLAGDelta169 also reduces DA-induced apoptotic cell death. Anti-oxidants N-acetylcysteine and catalase, which serve as scavengers of reactive oxygen species generated by metabolic DA oxidation, effectively block DA-induced JNK activation and subsequent apoptosis. Thus, our data suggest that DA triggers an apoptotic death program through an oxidative stress-involved JNK activation signaling pathway. Given the fact that the anti-oxidative defense system declines during aging, this molecular event may be implicated in the age-related striatal neuronal cell loss and age-related dopaminergic neurodegenerative disorders, such as Parkinson's and Huntington's diseases.
Patterned Hydrogenation of Graphene: Magnetic Quantum Dot Array (2009)

We design a new class of chemically modified graphenes through selective hydrogenation, which contain an array of triangular carbon domains separated by hydrogenated carbon stripes. By using a density-functional theory method within the generalized gradient approximation in the Perdew-Burke-Ernzerhof functional form, we show that each carbon triangle possesses notable magnetic moment on the edges. The chemically patterned graphene can be also viewed as an array of semiconducting quantum dots, where the hydrogenated carbon stripes play the role of quantum confinement. By adjusting the width of hydrogenated carbon stripes or the length scale of uncoated carbon triangles, the magnetic moment, band gap, and optical properties of the selectively hydrogenated graphene can be tuned.
Low-frequency noise from large wind turbines (2011)

As wind turbines get larger, worries have emerged that the turbine noise would move down in frequency and that the low-frequency noise would cause annoyance for the neighbors. The noise emission from 48 wind turbines with nominal electric power up to 3.6 MW is analyzed and discussed. The relative amount of low-frequency noise is higher for large turbines (2.3-3.6 MW) than for small turbines (≤ 2 MW), and the difference is statistically significant. The difference can also be expressed as a downward shift of the spectrum of approximately one-third of an octave. A further shift of similar size is suggested for future turbines in the 10-MW range. Due to the air absorption, the higher low-frequency content becomes even more pronounced, when sound pressure levels in relevant neighbor distances are considered. Even when A-weighted levels are considered, a substantial part of the noise is at low frequencies, and for several of the investigated large turbines, the one-third-octave band with the highest level is at or below 250 Hz. It is thus beyond any doubt that the low-frequency part of the spectrum plays an important role in the noise at the neighbors.
The Unexpected Role for the Aryl Hydrocarbon Receptor on Susceptibility to Experimental Toxoplasmosis (2010)

The aryl hydrocarbon receptor (AhR) is part of a signaling system that is mainly triggered by xenobiotic agents. Increasing evidence suggests that AhR may regulate immunity to infections. To determine the role of AhR in the outcome of toxoplasmosis, we used AhR-/- and wild-type (WT) mice. Following an intraperitoneal infection with Toxoplasma gondii (T. gondii), AhR-/- mice succumbed significantly faster than WT mice and displayed greater liver damage as well as higher serum levels of tumor necrosis factor (TNF)-alpha, nitric oxide (NO), and IgE but lower IL-10 secretion. Interestingly, lower numbers of cysts were found in their brains. Increased mortality was associated with reduced expression of GATA-3, IL-10, and 5-LOX mRNA in spleen cells but higher expression of IFN-gamma mRNA. Additionally, peritoneal exudate cells from AhR-/- mice produced higher levels of IL-12 and IFN-gamma but lower TLR2 expression than WT mice. These findings suggest a role for AhR in limiting the inflammatory response during toxoplasmosis.
