ITG: A New Global GNSS Tropospheric Correction Model (2015)

Tropospheric correction models are receiving increasing attentions, as they play a crucial role in Global Navigation Satellite System (GNSS). Most commonly used models to date include the GPT2 series and the TropGrid2. In this study, we analyzed the advantages and disadvantages of existing models and developed a new model called the Improved Tropospheric Grid (ITG). ITG considers annual, semi-annual and diurnal variations, and includes multiple tropospheric parameters. The amplitude and initial phase of diurnal variation are estimated as a periodic function. ITG provides temperature, pressure, the weighted mean temperature (Tm) and Zenith Wet Delay (ZWD). We conducted a performance comparison among the proposed ITG model and previous ones, in terms of meteorological measurements from 698 observation stations, Zenith Total Delay (ZTD) products from 280 International GNSS Service (IGS) station and Tm from Global Geodetic Observing System (GGOS) products. Results indicate that ITG offers the best performance on the whole.
Prenatal diagnosis of mosaic distal 5p deletion and review of the literature (2004)

The cri-du-chat syndrome can be identified prenatally because of advanced maternal age, familial cri-du-chat syndrome, parental balanced translocations involving chromosome 5, sonographically detected fetal structural abnormalities, and/or an abnormal maternal serum test. Fetuses with the mosaic distal 5p deletion may be associated with the sonographic findings of microcephaly and cerebellar hypoplasia, and fetoplacental and fetoamnionic chromosomal discrepancies.
Effective method for the computation of optical spectra of large molecules at finite temperature including the Duschinsky and Herzberg–Teller effect: The Qx band of porphyrin as a case study (2008)

The authors extend their recent method for the computation of vibrationally resolved optical spectra of large molecules, including both the Duschinsky rotation and the effect of finite temperature in the framework of the Franck-Condon (FC) approximation, to deal with the more general case of the Herzberg-Teller (HT) model, where also the linear dependence of the transition dipole moment on the nuclear coordinates is taken into account. This generalization allows us to investigate weak and vibronically allowed transitions by far extending the range of application of the method. The calculation of the spectra of sizable molecules is computationally demanding because of the huge number of final vibrational states that must be taken into account, and the inclusion of HT terms further increases the computational burden. The method presented here automatically selects the relevant vibronic contributions to the spectrum, independent of their frequency, and it is able to provide fully converged spectra with a modest computational requirement. The effectiveness of the method is illustrated by computing the HT absorption and fluorescence Q(x) spectra of free-base porphyrin both at T=0 K and at room temperature, performing for the first time an exact treatment of vibrations in harmonic approximation. Q(x) spectra are compared to experiments and FC/HT interferences are analyzed in detail.
Theory of Capillary Flow: I. Practical Implications (1955)

Abstract The authors describe elsewhere certain general consequences of assuming that the classical differential equations of surface tension and viscous flow govern the behavior of liquids within the microscopic pores and channels of an unsaturated porous medium. These consequences appear as macroscopic differential equations expressed in reduced variables and containing two time‐independent functionals of pressure which exhibit hysteresis and are characteristic of the medium. The present paper interprets these equations in practical terms. Because of time independence, the term ▽ K appearing in L. A. Richard's analogous equation (1931) becomes . Accordingly it is possible to solve for the conductivity and capacity functionals from experimental flow system data, provided the accuracy is sufficient for evaluation of required derivatives of pressure. The combination of reduced variables and time independence permits scale modeling of flow systems. In a small‐scale replica, the time scale is shortened, while “gravity” must be increased by means of a centrifuge. One possible application is to laboratory measurement of field capacity. The reduced variables telescope into groups macroscopic flow systems that are equivalent except for scaling factors. Reducing the microscopic geometry by comparison to a characteristic pore size may prove useful in simplifying physical description of soils.
Cell Polarity Signaling in <i>Arabidopsis</i> (2008)

Cell polarization is intimately linked to plant development, growth, and responses to the environment. Major advances have been made in our understanding of the signaling pathways and networks that regulate cell polarity in plants owing to recent studies on several model systems, e.g., tip growth in pollen tubes, cell morphogenesis in the leaf epidermis, and polar localization of PINs. From these studies we have learned that plant cells use conserved mechanisms such as Rho family GTPases to integrate both plant-specific and conserved polarity cues and to coordinate the cytoskeketon dynamics/reorganization and vesicular trafficking required for polarity establishment and maintenance. This review focuses upon signaling mechanisms for cell polarity formation in Arabidopsis, with an emphasis on Rho GTPase signaling in polarized cell growth and how these mechanisms compare with those for cell polarity signaling in yeast and animal systems.
Danazol for Children With Immune Thrombocytopenic Purpura (1988)

Ten patients with steroid-dependent or refractory immune thrombocytopenic purpura were treated with danazol in an attempt to improve their platelet counts. Nine of the ten children exhibited an excellent initial response to the drug, with five achieving a complete, unmaintained remission. Two others were able to have their prednisone doses tapered with a resultant disappearance of steroid-induced adverse effects. No significant adverse effects of danazol were noted. Danazol seems to be effective in the treatment of children with immune thrombocytopenic purpura and would warrant additional studies to determine its proper role in the management of this common pediatric ailment.
Large-Signal Technique for Designing Single-Frequency and Voltage-Controlled GaAs FET Oscillators (1981)

A systematic procedure is described for designing fixed-frequency and voltage-tuned GaAs FET oscillators for optimum large-signal performance. The approach is based on the use of a large-signal FET model for de-embedding dominant device nonlinearities, leading to a method which is both accurate and simple to apply. The viability of the technique is demonstrated with a 17-GHz fixed-frequency oscillator and a 7.4 to 13.1-GHz varactor-tuned oscillator. Design considerations as well measured performance characteristics are discussed in detail.
Pleiotropic effects of rosuvastatin on the glucose metabolism and the subcutaneous and visceral adipose tissue behavior in C57Bl/6 mice (2013)

The aim of this study was to evaluate whether rosuvastatin (HMG-CoA reductase inhibitor) modulates the carbohydrate and lipid metabolism, the development of non-alcoholic fatty liver disease (NAFLD), and the increase in body mass in a model of diet-induced obesity. Male C57Bl/6 mice (3-months-old) were fed a high-fat diet (HF, 60% lipids) or the standard chow (SC, 10% lipids) for 15 weeks. The animals were then treated with 10 mg/kg/day (HF-R10 group), 20 mg/kg/day (HF-R20), or 40 mg/kg/day (HF-R40) of rosuvastatin for five weeks. The HF diet led to glucose intolerance, insulin resistance, weight gain, increased visceral adiposity with adipocyte hypertrophy, and hepatic steatosis (micro and macrovesicular). The rosuvastatin treatment decreased the adiposity and the adipocyte size in the HF-R10 and HF-R20 groups. In addition, rosuvastatin changed the pattern of fat distribution in the HF-R40 group because more fat was stored subcutaneously than in visceral depots. This redistribution improved the fasting glucose and the glucose intolerance. Rosuvastatin also improved the liver morphology and ultrastructure in a dose-dependent manner. In conclusion, rosuvastatin exerts pleiotropic effects through a dose-dependent improvement of glucose intolerance, insulin sensitivity and NAFLD and changes the fat distribution from visceral to subcutaneous fat depots in a mouse model of diet-induced obesity.
Contesting the nation through a genealogy of girl consciousness (2004)

Gender, age, and language spoken in the home are associated with baseline scores on multiple components of the Child SCAT5 among middle school students, although the magnitudes of observed differences are small. Normative reference values are provided for clinicians when interpreting Child SCAT5 scores.
Clinical Application of Voriconazole Concentrations in the Treatment of Invasive Aspergillosis (2008)

A standardized therapeutic range for voriconazole has not been defined. Most available studies recommend trough concentrations of approximately 1-6 microg/mL. Prospective, randomized trials are needed to confirm the correlation between plasma voriconazole concentrations and clinical outcomes.
In-Situ Loading Ultrafine AuPd Particles on Ceria: Highly Active Catalyst for Solvent-Free Selective Oxidation of Benzyl Alcohol (2010)

Ce(III) oxide was synthesized under the protection of nitrogen gas, which had strong ability to reduce noble metal ions (e.g., Au, Pd ions) into metallic forms under oxygen-free conditions. On the basis of the surface redox reaction between the Ce(III) oxide support and noble metal ions, an effective and novel approach was presented to prepare noble metal/CeO(2) nanocatalysts, and a series of AuPd/CeO(2) nanocomposites with different Au:Pd molar ratios and metal loadings were obtained in the absence of any extra reducing and protective agents. The resultant composites were characterized by different techniques including X-ray diffraction, transmission electron microspectroscopy, X-ray photoelectron microspectroscopy, and ICP-AES analysis. It was demonstrated that in the AuPd/CeO(2) composites the content of Ce(III) reached about 30%, and the AuPd bimetallic particles with average size of 2.6 or 3.3 nm and narrow size distribution were uniformly distributed on the CeO(2) nanorods. The AuPd/CeO(2) composites were found to be excellent heterogeneous nanocatalysts for the selective oxidation of benzyl alcohol under solvent-free conditions. It was shown that all the AuPd/CeO(2) catalysts exhibited good selectivity toward benzaldehyde; especially, the catalyst with Au:Pd = 1:5 and metal loading of 1.2 wt % displayed extremely high activity with a TOF = 30.1 s(-1) at 160 °C.
Novel CT detector based on an inorganic scintillator working in photon-counting mode (2006)

Detectors working in photon counting mode offer an interesting alternative to the common charge integrating detectors for computed tomography (CT), because they can potentially measure the energy of every detected X-ray photons and achieve better image contrast sensitivity for a given dose. Unfortunately, most current X-ray detectors suffer from limited count rate capability, due either to a long charge migration time in semiconductor and gas detectors, or to a slow decay time in ceramic scintillators. To overcome these difficulties, we propose to use pixel detectors based on fast light emitting inorganic scintillators individually coupled to avalanche photodiodes with parallel, low-noise, fast digital processing electronics to provide real time single event detection and recording. The proposed detector was investigated with 2 × 2 × 10 mm<sup>3</sup> Lu<sub>1.9</sub>Y<sub>0.1</sub>SiO<sub>5</sub> (LYSO), a fast decay time (40 ns), heavy (7.19 g/cc) scintillator that is also suitable for coincidence detection of annihilation radiation (511 keV) in positron emission tomography (PET). Therefore, the detector characteristics make it a good candidate for implementation in a combined PET/CT dual-modality scanner. Although only coarse spectral analysis is possible in the X-ray energy range, it is demonstrated that appropriate CT images for anatomical localization can be obtained at very low dose in counting mode using a PET/CT simulator set up for small animal imaging. Data are reported on CT image resolution, noise, contrast and dose.
Post-recurrence survival in completely resected stage I non-small cell lung cancer with local recurrence (2009)

Treatment for initial recurrence is a prognostic predictor for post-recurrence survival in resected stage I NSCLC with local recurrence. Complete surgical resection should be considered in selected candidates with resectable local recurrent disease.
Run Time Mitigation of Performance Degradation Hardware Trojan Attacks in Network on Chip (2018)

Globalization of semiconductor design and manufacturing has led to several hardware security issues. The problem of Hardware Trojans (HT) is one such security issue discussed widely in industry and academia. Adversary design engineer can insert the HT to leak confidential data, cause a denial of service attack or any other intention specific to the design. HT in cryptographic modules and processors are widely discussed. HT in Multi-Processor System on Chips (MPSoC) are also catastrophic, as most of the military applications use MPSoCs. Network on Chips (NoC) are standard communication infrastructure in modern day MPSoC. In this paper, we present a novel hardware Trojan which is capable of inducing performance degradation and denial of service attacks in a NoC. The presence of the Hardware Trojan in a NoC can compromise the crucial details of packets communicated through NoC. The proposed Trojan is triggered by a particular complex bit pattern from input messages and tries to mislead the packets away from the destined addresses. A mitigation method based on bit shuffling mechanism inside the router with a key directly extracted from input message is proposed to limit the adverse effects of the Trojan. The performance of a 4×4 NoC is evaluated under uniform traffic with the proposed Trojan and mitigation method. Simulation results show that the proposed mitigation scheme is useful in limiting the malicious effect of hardware Trojan.

Improving Recommendations by Using Personality Traits in User Profiles (2008)

By storing Personality Traits in User Profiles we able Recommender Systems to deduce more interesting recommendations for users acting pro-actively in order to offer for them products/services as a prediction of their future needs and behavior. This paper is proposed as an alternative to improve the robustness of recommendations by using psychological aspects, as Personality Traits. This paper is a part of a PhD ongoing work. It is presented as follow: firstly we give a brief introduction about the importance of using psychological aspects in User Profiles during the decision making process; secondly, we describe studies done in Psychology describing Personality, Traits and Tests in order to formalize how to define, to model and to extract Personality Traits of user to define his identity and to build his Profile; after, we describe how the User Reputation is formalized followed by a brief consideration about Recommender Systems; finally we present our experimentation followed by results and conclusions.
Failure Criteria for Unidirectional Fiber Composites (1980)

Three-dimensional failure criteria of unidirectional fiber composites are established in terms of quadratic stress polynomials which are expressed in terms of the transversely isotropic invariants of the applied average stress state. Four distinct failure modes—tensile and compressive fiber and matrix modes—are modeled separately, resulting in a piecewise smooth failure surface.

Symbol-by-symbol MAP decoding of convolutional codes using reciprocal dual convolutional codes (2002)

A new symbol-by-symbol maximum a-posteriori (MAP) decoding algorithm for high-rate convolutional codes using reciprocal dual convolutional codes is presented. It fulfills all the requirements for iterative (turbo) decoding of parallel concatenated convolutional codes. The computational complexity is low due to the fact that the number of codewords of the low-rate reciprocal dual code is much less than that of the high-rate code. For an efficient implementation forward and backward recursions are introduced.
Eye Fixation And Early Vision: Kinetic Depth (2005)

One aspect of primate intelligence is the ability to coordinate eye movements in the process of solving complex tasks. Primate eye movements have been studied in several disciplines but little work has been directed toward a computational theory that shows how the eye nouements can confer specific advantages in problem-solving behaviors, This paper outlines some of the elements of such a theory, emphasizing one point: the advantages of an active system in choosing an external frame of reference for the computations of early vision. These advantages are illustrated by the real-time computation of depth map with a monocular, fixating vision system.
Towards an intelligent system for clinical guidance on wheelchair tilt and recline usage (2012)

We propose to construct an intelligent system for clinical guidance on how to effectively use power wheelchair tilt and recline functions. The motivations fall into the following two aspects. (1) People with spinal cord injury (SCI) are vulnerable to pressure ulcers. SCI can lead to structural and functional changes below the injury level that may predispose individuals to tissue breakdown. As a result, pressure ulcers can significantly affect the quality of life, including pain, infection, altered body image, and even mortality. (2) Clinically, wheelchair power seat function, i.e., tilt and recline, is recommended for relieving sitting-induced pressures. The goal is to increase skin blood flow for the ischemic soft tissues to avoid irreversible damage. Due to variations in the level and completeness of SCI, the effectiveness of using wheelchair tilt and recline to reduce pressure ulcer risks has considerable room for improvement. Our previous study indicated that the blood flow of people with SCI may respond very differently to wheelchair tilt and recline settings. In this study, we propose to use the artificial neural network (ANN) to predict how wheelchair power seat functions affect blood flow response to seating pressure. This is regression learning because the predicted outputs are numerical values. Besides the challenging nature of regression learning, ANN may suffer from the overfitting problem which, when occurring, leads to poor predictive quality (i.e., cannot generalize). We propose using the particle swarm optimization (PSO) algorithm to train ANN to mitigate the impact of overfitting so that ANN can make correct predictions on both existing and new data. Experimental results show that the proposed approach is promising to improve ANN's predictive quality for new data.
50-nm vertical sidewall transistors with high channel doping concentrations (2002)

Vertical MOSFETs have been proposed in the roadmap of semiconductors as a candidate for sub 100 nm CMOS technologies. A process flow using sidewall gates and implantations instead of multiple layer depositions reduces process complexity and offers better CMOS compatibility. High doping concentrations in the channel are needed for sub 100 nm devices. Especially for vertical transistors the uniform channel doping is more critical than for a planar technology, where optimized profiles can be easier implemented. Therefore, we investigated for the first time vertical MOSFETs with high channel doping concentration up to 1*10/sup 19/ cm/sup -3/ and channel lengths down to 50 nm. The impact of the high doping levels on threshold voltage and on tunneling currents is discussed. Finally, by using slight process modifications first results on vertical double gate MOSFETs will be presented, which in principle can operate with an undoped channel region.
Interfacial reaction between a Ni/Ge bilayer and silicon (100) (1990)

The sequential formation and dissociation of compounds in the Ni/Ge/Si(100) system have been studied by using Rutherford backscattering spectroscopy, Auger depth profiling, x-ray diffraction, and cross-sectional transmission electron microscopy. Ni2Ge phase is formed first on the Si substrate at 250 °C. A layered structure of NiGe/NiSi/Si(100) is formed after thermal annealing at 350 °C. Upon annealing from 350 to 425 °C, the NiGe phase dissociates, inducing further growth of NiSi phase at the nickel germanide/Si(100) interface. The NiSi phase grows with a (time)1/2 dependence and with an activation energy of 2.1 eV. Marker experiment shows that Ni is a dominant moving species. The dissociation of NiGe lead to an extensive redistribution of Ge and Ni with a configuration of Ge66Si17Ni17/NiSi/Si(100) and this layered structure remains stable until 680 °C. Cross-sectional transmission electron microscopy results show that there are polycrystalline Ge plus a ternary NiSiGe phase on the top layer. High-temperature annealing (&gt;680 °C) induces the inward diffusion of Ge to form a Ge-rich layer on the Si substrate.
Nontouch Biofield Therapy: A Systematic Review of Human Randomized Controlled Trials Reporting Use of Only Nonphysical Contact Treatment (2014)

The pilot study nature of essentially all the identified nonphysical contact biofield therapy RCTs, as reflected by low sample sizes alone, precludes drawing robust conclusions. Given this perspective, the finding that two thirds of the higher-scoring trials demonstrated at least partial effectiveness favors a continued research effort, especially in light of the translational value of biofield clinical trials for studies exploring the nature and physiologic basis of biofield healing.
