We have extended the tunneling ionization model of Ammosov-Delone-Krainov ~ADK! for atoms to diatomic molecules by considering the symmetry property and the asymptotic behavior of the molecular electronic wave function. The structure parameters of several molecules needed for calculating the ionization rates using this molecular ADK model have been obtained. The theory is applied to calculate the ratios of ionization signals for diatomic molecules with their companion atoms that have nearly iden ...
The lower incidence of allergy and autoimmune diseases in developing countries has been associated with a high prevalence of parasitic infection. Here we provide direct experimental evidence that parasites can exert bystander immunosuppression of pathogenic T cells that mediate autoimmune diseases. Infection of mice with Fasciola hepatica resulted in recruitment or activation of regulatory dendritic cells and macrophages that expressed IL-10 and TGF-β. ...
Performance parameters of BAW devices are reviewed and ranked corresponding to their importance for RF-filters in mobile phone applications. The most important performance parameters - such as resonator bandwidth and Q-values - critically depend on the quality of the piezolayer and other relevant layers in the acoustic stack. The design of the complete layer stack in a Solidly Mounted Resonator (SMR) concept in combination with a proper design of lateral resonator-boundaries will be revealed to ...
Curcumin, a natural compound, is a well-known chemopreventive agent with potent anticarcinogenic activity in a wide variety of tumor cells. Curcumin inhibits cancer cell proliferation in part by suppressing cyclin D1 and inducing expression of the cyclin-dependent kinase inhibitor p21. Both p53-dependent and p53-independent mechanisms regulate p21 expression, but the mechanism by which curcumin regulates p21 expression remains unknown. Here, we report that transcription of the p21 gene is activa ...
Multi-dimension bucketization is a typical method to anonymize multiple sensitive attributes. However, the method leads to low data utility when microdata have more sensitive attributes. In addition, the methods do not generalize quasi-identifiers, which make the anonymous data vulnerable to suffer from linked attacks. To address the problems, the paper proposes a SLOMS method. The method vertically partitions the multiple sensitive attributes into several tables and bucketizes each sensitive at ...
Vmpfc is correlated with recovery even the number of alternative treatments these studies. The locus of brain injury he was supported in resting. This study using the use of, negative emotion. This type of self reflection and although the scalp generates a major depressive symptoms. Unlike tms which consists entirely of focal brain. That depression with the key neural, substrates underlying cortex play a plausible. Functional imaging studies associate depression with vmpfc and in both hemisphere ...
The Japanese pear pathotype of Alternaria alternata, a toxin-dependent necrotrophic pathogen, causes black spot of Japanese pear by producing the host-specific AK-toxin. Pre-inoculation with nonpathogenic A. alternata or pretreatment with an elicitor prepared from A. alternata reduced disease symptoms caused by the pathogen. Salicylic acid- and jasmonic acid-dependent signaling pathways are not involved in the induced resistance to infection by the pathogen. The expression of multiple defense-re ...
Microwave Photonics (MWP) is a discipline which offers new opportunities to Low-Coherence Interferometry (LCI). In this paper, a novel MWP-LCI technique is presented by means of a well-established parallelism between both worlds, MWP and LCI. This technique is based on the slicing of a broadband source which is transmitted through a dispersive element. The optical path differences under test modify the electrical transfer function of the MWP-LCI subsystem through a interferometric structure. In ...
Measurements of positron-on-molecule annihilation have established that positrons attach to a variety of molecules via vibrational Feshbach resonances VFRs . These resonances, in turn, result in greatly enhanced positron annihilation rates beyond those expected in simple collisions. A recent paper J. A. Young and C. M. Surko, Phys. Rev. Lett. 99, 133201 2007 described experimental studies and analysis of positron annihilation in large molecules. Presented here is a more complete description of t ...
Over two seasons, two trials were conducted to assess the at-planting use of insecticides for the suppression of Fulmekiola serrata (Kobus) (Thysenoptera: Thripidae) in sugarcane. Products tested in the first trial were two formulations of imidacloprid as well as aldicarb and oxamyl. In the second trial three rates of each imidacloprid formulation were tested and two rates of carbofuran. Crops were planted monthly from October to December in the first trial and from September to December in the ...
An active control approach was developed to observe and control nonlinear distortions in high amplitude acoustic waves in a rigid-walled, two-radii harmonic resonator. The medium was air at ambient pressure and temperature. The resonator was first driven with a single-frequency waveform near the fundamental resonant frequency in generating standing waves with characteristic pressure amplitudes of 1400 Pa. The nonlinearly excited harmonics due to quadratic and cubic nonlinear coupling effects wer ...
Reho JJ, Fisher SA. The stress of maternal separation causes misprogramming in the postnatal maturation of rat resistance arteries. Am J Physiol Heart Circ Physiol 309: H1468–H1478, 2015. First published September 14, 2015; doi:10.1152/ajpheart.00567.2015.—We examined the effect of stress in the first 2 wk of life induced by brief periods of daily maternal separation on developmental programming of rat small resistance mesenteric arteries (MAs). In MAs of littermate controls, mRNAs encoding ...
A novel method using resonant coils of different sizes is proposed to suppress frequency splitting in wireless power transfer (WPT). Frequency splitting is caused by excessive mutual inductance between transmitter and receiver, and can be suppressed by reasonably designing the sizes of the transmitter and receiver to eliminate the pole value of the mutual inductance. Theory calculation are conducted to present the transfer efficiency of WPT adopting the proposed method. Frequency splitting is re ...
In this paper, we investigate the variability of the drain current, induced by random doping fluctuation, of junctionless nanoscale double-gate transistors. Using accurate statistical and quantum-corrected Technology Computer Aided Design simulation (10 000 randomizations), we investigate the current variability as function of the gate and drain voltage (ranging from the OFF to the ON regime), the device doping, and the device geometry. The dispersion of the drain current in the ON regime is fou ...
LORAMbis is the experimental part of a joint research program between Sweden and France. The objective is to evaluate the performance of low frequency bistatic SAR for clutter suppression in various applications, e.g. under-foliage target detection or mapping of urban scenes. The airborne bistatic SAR data are acquired using the VHF/UHF component of the ONERA SAR system SETHI and the VHF/UHF LORA system operated by FOI. The first data collection campaign was conducted in December 2009. Focused b ...
The EGF receptor (EGFR) is amplified and mutated in glioblastoma, in which its common mutation (DEGFR, also called EGFRvIII) has a variety of activities that promote growth and inhibit death, thereby conferring a strong tumor-enhancing effect. This range of activities suggested to us that DEGFR might exert its influence through pleiotropic effectors, and we hypothesized that microRNAs might serve such a function. Here, we report that DEGFR specifically suppresses one such microRNA, namely miR-9, ...
Control of a moving liquid container is challenging because of unwanted transient and residual slosh. Although significant progress has been achieved at eliminating the fundamental sloshing mode, less success has been achieved with designing a controller to suppress slosh for an infinite number of modes. This study presented two methods to reduce an infinite number of sloshing modes in a moving liquid container. The first method is command smoothing to eliminate slosh by using the first-mode fre ...
The low-temperature thermal conductivity κ0/T of d-wave superconductors is generally thought to attain a “universal” value independent of disorder at sufficiently low temperatures, providing an important measure of the magnitude of the gap slope near its nodes. We discuss situations in which this inference can break down because of competing order, and quasiparticle localization. Specifically, we study an inhomogeneous BCS mean field model with electronic correlations included via a Hartree ...
This paper gives the characteristics of single-phase earth fault and ferro-resonance, then proposes two methods that adopt restricting the recovery rate of fault phase voltage to replace the Peterson-coil: using metal-oxide nonlinear resistance to extinguish electric arc, or making the fault phase metallic grounded, then the ferro-resonance which is more harm to system is changed into metallic grounded fault. After that, this paper proposes that changes the parameter of system instantaneously, a ...
While the proliferation of Russia's top tier SAMs into the Asian market has been dominated by Chinese large volume purchases, with India still negotiating, we are now seeing a second wave of 'me too' buys by smaller nations intent on matching their larger neighbours. Without the attached political strings of US equipment, and often much cheaper than US equivalents, top tier Russian products often match and sometimes exceed their US competitors in key performance specs or capabilities. The Almaz ...
This paper introduces an effective approach for differentially exciting the rectangular dielectric resonator (DR), which lays a foundation for designing balanced DR bandpass filters (BPFs). By analyzing the properties of the DR, it can be found that the TE<sub>11δ</sub> mode can be used for differential-mode (DM) operation while TM<sub>11δ</sub> mode can be used for common-mode (CM) operation. Meanwhile, the two modes are split by drilling a hole at the cent ...
DRIED THYROID SUBSTANCE or the pure natural hormoue s, L-thyroxin and L-triiodothyronine, effect a reduction in the serum total cholesterol of euthyroid individuals when administered in sufficient allmount.1-3 Their general clinical use to reduce elevated serum cholesterol levels in the hope of favorably influencing the course of atherosclerosis has been limited by two factors. When given in moderate dosage, dried thyroid substance effected a prompt reduction in serum cholesterol, but despite co ...
Extraction of the foetal electrocardiogram from single-channel maternal abdominal signals without disturbing its morphology is difficult. We propose to solve the problem by application of projective filtering of time-aligned ECG beats. The method performs synchronization of the beats and then employs the rules of principal component analysis to the desired ECG reconstruction. In the first stage, the method is applied to the composite abdominal signals, containing maternal ECG, foetal ECG, and va ...
We calculate the factor by which thermal phase fluctuations, as distinct from phase-slip fluctuations, increase the inductance LJ of a resistively shunted Josephson junction ~JJ! above its mean-field value L0 . We find that quantum mechanics suppresses fluctuations when T drops below a temperature, TQ5\/kBGL0 , where G is the shunt conductance. Examination of the calculated sheet inductance LA(T)/L0(T) of arrays of JJ’s reveals that two-dimensional ~2D! interconnections halve fluctuation effec ...
Several studies in the hamster model were undertaken to investigate known and recently disclosed metabolic interactions between bile acids and lipoproteins, particularly between ursodiol and low-density-lipoprotein (LDL) receptors. Three groups of animals, receiving a control 0.027% cholesterol diet, supplementation with 0.1% ursodiol, or supplementation with 0.1% chenodeoxycholic acid, were treated for four weeks. Both bile acids suppressed bile acid synthesis. Chenodeoxycholic acid significant ...
A method for analytic continuation of imaginary-time correlation functions (here obtained in quantum Monte Carlo simulations) to real-frequency spectral functions is proposed. Stochastically sampling a spectrum parametrized by a large number of delta-functions, treated as a statisticalmechanics problem, it avoids distortions caused by (as demonstrated here) configurational entropy in previous sampling methods. The key development is the suppression of entropy by constraining the spectral weight ...
An adaptive circuit is proposed to adjust CDR loop bandwidth based on different jitter spectral profile for better jitter performance. The preventional lock detector (PLD) is employed to achieve better jitter suppression ability without jitter tolerance (JTOL) degradation. The proposed circuit enhances the jitter suppression by 14.14 dB at an 8-MHz sinusoidal jitter source. This adaptive block is fully-digital synthesized and the whole circuit consumes 86.4 mW for a 6-Gb/s input data. ...
In this contribution we first derive the correlation coefficient of two subcarriers in multicarrier systems using cyclic-prefixing (CP) for inter-symbol interference (ISI) suppression and inverse fast Fourier transform (IFFT)/fast Fourier transform (FFT) for multicarrier modulation/demodulation. It can be shown that two subcarriers spaced far away may experience highly correlated fading. Then, the probability density function (PDF) of fading amplitudes of subcarrier signals is derived, showing t ...
The power deposition in the plasma is primarily determined by the magnetic field B(r). For a single frequency ECRH system this has the consequence that for central heating the magnetic field is no longer a free parameter. However, for plasmas with different plasma currents or different equilibria, the magnetic field should be a free parameter in order to operate at a reasonable edge safety factor q(a). Furthermore, in a plasma with given parameters, some experimental features, like suppression o ...
This letter introduces double layer layouts of open-circuit lines into the electromagnetic bandgap (EBG) structures to enable changing the shunt circuit of the parallel plate waveguide to inductance in compact spaces. That is, compact EBG structures were achieved. The EBG structures, fabricated using standard fabrication processes and using a low-cost substrate (flame retardant type 4), enable a 1-mm-order size for a 2.4-GHz BG. The size is less than 1/10 of the conventional mushroom structures ...
It has been reported that p.o. administration of dialiyl sulfide (DAS), a naturally occurring component of garlic (Allium sativum), inhibits 1,2dimethylhydrazine-induced colon and liver cancer in rodents. A possible mechanism for this protective effect is inhibition of hepatic activation of the procarcinogen. The effect of DAS on P450IIE1, an isozyme of cytochrome P-450 which is active in the oxidative metabolism of dimethylhydrazine, was conveniently assayed in the present study by de terminati ...
In this paper, we mathematically analyze one of the most challenging issues in color image-guided depth upsampling: the texture copy artifacts. The optimal guidance weights denoted by balanced weights are proposed to best suppress texture copy artifacts. To both suppress texture copy artifacts and preserve depth discontinuities, a new general weighting scheme called variable bandwidth weighting is proposed. The variable bandwidth weighting scheme is able to adjust guidance weights according to t ...
The in vitro study of the interactions between S. mutans and S. sobrinus is important to determine the role of these microorganisms in the formation of biofilms on dental structures and their potential to induce carious lesions. The objective of this research was to study the suppression of bacterial plaque formation and its recolonization by rifampycin-resistant S.mutans and streptomycin-resistant S. sobrinus. To study the competitive relationship between these species, previously standardized ...

MATERIAL AND METHODS: Cushing’s disease was diagnosed in a 27 year old male on the basis of clinical and biochemical findings. The blood cortisol level of the patient was elevated (the average level was 47 ug/dl) and it showed no changeability of day and night rhythm. ...
Influenza is an annual, global health care concern. Secondary bacterial pneumonia is a severe complication associated with primary influenza virus infection, often resulting in critical morbidity and mortality. Our laboratory has identified influenza-induced suppression of anti-bacterial Type 17 immunity as a mechanism for enhanced susceptibility to bacterial super-infection. We have shown that influenza-induced type I interferon impairs Type 17 activation. STAT1 is a transcription factor involv ...

The aim of the research is to attenuate the radial periodic vibration of active magnetic bearing (AMB) rotors. In this paper, a controller combining repetitive control (RC) and linear auto disturbance rejection control (LADRC) is proposed for an AMB system. The proposed approach has the added advantage that the design of the two controllers is independent of each other. The LADEC method ensures the system dynamic response, and the RC method is used to remove the periodic disturbance from the rot ...
Power-Law detector based on DFT is developed to detect a moving dim target under heavy infrared background. Because that the grey-scale value of a pixel in an image occurs fluctuation when a target passes by, this fluctuation can be viewed as a weak transient signal, and the Power-Law processor has advanced performance on transient signal detection. Firstly, a time window, length of L frames, is introduced in the algorithm. And then, the current frame at the center of the window is processed wit ...
Bioluminescence is a common feature in coastal waters where luminescent plankton can be abundant, and is commonly stimulated by fluid agitation. In the context of Navy nighttime operations, swimmers or underwater vehicles are vulnerable to detection due to their stimulation of bioluminescence. The objective of this study is to investigate the effectiveness of electromagnetic fields in reducing flow-stimulated bioluminescence. Dinoflagellates, plankton ubiquitous in coastal waters, are the most c ...
Power scaling of fiber laser systems requires the development of innovative active fibers, capable of providing high pump absorption, ultralarge effective area, high-order mode suppression, and resilience to thermal effects. Thermally induced refractive index change has been recently appointed as one major limitation to the achievable power, causing degradation of the modal properties and preventing to obtain stable diffraction-limited output beam. In this paper, the effects of thermally induced ...
Common-mode voltage (CMV) is one of the most important issues for the power electronics inverters. An interesting space vector modulation of the three-leg current-source inverter has been reported for the CMV reduction recently. However, it has the disadvantages of the bipolar current pulses and modulation index range limitation. In order to solve these problems, a four-leg current-source inverter with a new space vector modulation is proposed in this paper. With the proposed method, the system ...
In chickens, erythrocyte isoantigens have hapten-carrier relationships. Specific anticarrier antibody depresses the immune response to the carrier and enhances the immune response to the hapten. Antigenic determinants of "haptenic" isoantigens behave as carriers if they are coated with specific antibody. It is postulated that every humoral antibody response involves the cooperation of a carrier with a hapten and the progressive conversion by antibody of haptens to carriers. Thus a carrier is vie ...
115 As in many other conditions that affect the musculoskeletal system, pain and deformity are the two factors that prompt hallux valgus patients to visit a doctor in search of a remedy. Any treatment we propose should therefore achieve these two purposes: the suppression of pain and the correction of the deformation. In 50% of cases, attaining the latter without the former far from leading to a success, leads to utter failure. Given the nature of hallux valgus, treatment should be at the same t ...
Purpose: Dual blockade of HER2 with trastuzumab and lapatinib or with pertuzumab is a superior treatment approach compared with single-agent HER2 inhibitors. However, many HER2-overexpressing breast cancers still escape from this combinatorial approach. Inhibition of HER2 and downstream phosphoinositide 3-kinase (PI3K)/AKT causes a transcriptional and posttranslational upregulation of HER3 which, in turn, counteracts the antitumor action of the HER2-directed therapies. We hypothesized that suppr ...

The position detection with induction radio and the principle of data communication has been introduced, and both general and high resolution position detection methods have been deduced. Then the similar frequency interferen ...
In this paper a problem in transient noise suppression for audio streams in laptop and netbook devices is addressed. One or more microphones record voice signals which are corrupted with ambient noise and also transient noise from keyboard and mouse clicks. In the current work, a synchronous reference microphone is embedded in the keyboard which allows for measurement of the key click noise, substantially unaffected by the voice signal and ambient noise. An algorithm is here presented for incorp ...
A closed three-dimension discrete-time map of current-mode controlled Boost converter is presented in this paper. By researching this bifurcation diagram, we can make current-mode controlled Boost converter operating in chaos by selecting appropriate parameter. The simulation results demonstrate that current-mode controlled Boost converters in self-excitation-chaos can suppress Electro-magnetic Interference very well, hardly influence to output voltage ripples. ...
“Fuzzy CP2”, which is a four-dimensional fuzzy manifold analogous to the fuzzy 2-sphere (S2), appears as a classical solution in the dimensionally reduced 8d YangMills model with a cubic term involving the structure constant of the SU(3) Lie algebra. Although the fuzzy S2, which is also a classical solution of the same model, has actually lower one-loop effective action than the fuzzy CP2, Monte Carlo simulation shows that the fuzzy CP2 is stable even nonperturbatively due to the suppression ...
The developmental success of Leptopilina boulardi parasitoids within host species of the melanogaster subgroup is determined mainly by their ability to suppress the host immune reaction (virulence). Host resistance and parasitoid virulence are genetically variable in both partners. A gene for specific resistance against L. boulardi (Rlb) has been identified in Drosophila melanogaster, and a gene for the immune suppression (IS) of D. melanogaster has been identified in L. boulardi. To understand ...
The anti-inflammatory effect of methotrexate (MTX) is mediated by the increasing extracellular concentration of adenosine. The response of the immune system to activation of cell membrane subclass receptors for adenosine initiates intracellular signaling pathways, which causes immunomodulatory responses. To test the direct immunomodulatory effects of systemic administration of adenosine on animal model of inflammation, zymosan induced arthritis (ZIA) in mice was employed. Sterile zymosan (30 mg) ...

Summary form only given. Axi-symmetric mirror machines are the simplest magnetic confinement devices, and as such could be attractive for fusion machines, ions separation, and more. However, mirror machines suffer from particle loss due to the violent flute instability. We demonstrates for the first time the stabilization of fast growing, slowly rotating flute instability by multi-input, multi-output active feedback system.The feedback system consists of six optical probes, digital signal proces ...
