Post-growth process relaxation properties of strained Cd0.92Zn0.08Te/Cd0.83Zn0.17Te quantum well heterostructures grown by molecular beam epitaxy (2004)

The post-growth structural stability regarding relaxation and defect propagation in Cd0.83Zn0.17Te/Cd0.92Zn0.08Te/Cd0.83Zn0.17Te quantum well (QW) heterostructures grown on [001] oriented Cd0.88Zn0.12Te substrates at 300 °C by molecular beam epitaxy is investigated. The investigated heterostructures were subjected to post-growth thermal treatment in an ambient atmosphere in a temperature range between 280 and 550 °C for 3 h each. We have used high-resolution x-ray diffraction as the main characterization tool. High-resolution rocking curves as well as the powerful two-dimensional reciprocal space mapping were employed in both symmetrical as well as asymmetrical reflections. The results indicate that at a post-growth temperature cycle of 350 °C for 3 h slight modification of the Cd0.83Zn0.17Te/Cd0.92Zn0.08Te barrier/QW heterointerface smoothness is affected. This indicates the onset of migration of Zn atoms at this post-growth temperature time cycle. At 450 °C, this effect is more pronounced and seen as the complete disappearance of thickness fringes. For higher post-growth thermal treatment at 550 °C for 3 h, a high relaxation level accompanied by Zn content reduction is observed. A reduction of the Zn content down to 0.11 fractional value in the thick Cd0.83Zn0.17Te barrier is attributed to Zn out diffusion and/or Zn precipitation.

Lie Group Cohomology and (Multi)Symplectic Integrators: New Geometric Tools for Lie Group Machine Learning Based on Souriau Geometric Statistical Mechanics (2020)

In this paper, we describe and exploit a geometric framework for Gibbs probability densities and the associated concepts in statistical mechanics, which unifies several earlier works on the subject, including Souriau's symplectic model of statistical mechanics, its polysymplectic extension, Koszul model, and approaches developed in quantum information geometry. We emphasize the role of equivariance with respect to Lie group actions and the role of several concepts from geometric mechanics, such as momentum maps, Casimir functions, coadjoint orbits, and Lie-Poisson brackets with cocycles, as unifying structures appearing in various applications of this framework to information geometry and machine learning. For instance, we discuss the expression of the Fisher metric in presence of equivariance and we exploit the property of the entropy of the Souriau model as a Casimir function to apply a geometric model for energy preserving entropy production. We illustrate this framework with several examples including multivariate Gaussian probability densities, and the Bogoliubov-Kubo-Mori metric as a quantum version of the Fisher metric for quantum information on coadjoint orbits. We exploit this geometric setting and Lie group equivariance to present symplectic and multisymplectic variational Lie group integration schemes for some of the equations associated with Souriau symplectic and polysymplectic models, such as the Lie-Poisson equation with cocycle.

Structure and thermoelectric properties of PbTe films deposited by thermal evaporation method (2016)

Lead telluride (PbTe) thin films have been deposited on SiO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> substrate using thermal evaporation method. The structure of the films was found to have a face-centered cubic (fcc) with predominant grain growth in the (200) direction for both as-deposited and annealed samples up to 350 °C in vacuum for 1 h. The in-plain electrical resistivity and Hall measurements via van der Pauw method as a function of annealed temperatures were measured. It was found that increasing the annealing temperature led to increase in grain size, which in turn caused decrease of electrical resistivity and increase of Seebeck coefficient.

Abstract B132: Enhanced therapeutic effect of combined treatments with h7C10, a humanized antibody against insulin-like growth factor-1 receptor, and chemotherapeutic agents in xenograft models (2009)

Abstract IGF-1 receptor (IGF-1R) plays a key role in the development of numerous tumors. Blockade of IGF-1R axis using monoclonal antibodies constitutes an interesting approach to inhibit tumor growth. We have previously described h7C10, a humanized anti-IGF-1R Mab, that exhibits a potent anti-tumor activity both in vitro and in vivo. It blocks IGF-1 and IGF-2 induced signaling, inhibits cell proliferation and colony formation, induces cell cycle arrest and promotes IGF-1R degradation. In this report, a panel of combinations of h7C10 with chemotherapeutic drugs were tested in vivo in xenograft models based on preliminary studies performed in vitro using the method described by Chou and Talalay. Our results confirmed a significant benefit of in vivo combinations of h7C10 with doxorubicin, docetaxel and paclitaxel. Data were less clear when h7C10 was combined to gemcitabine. An interesting combined effect was also noticed in mice treated by both h7C10 and 5-FU. These findings demonstrate that h7C10 combined with established cancer therapeutics is highly effective in vivo against tumors expressing IGF-1R and support clinical evaluation of h7C10 in combination with these drugs for the treatment of human cancers.

Th17 Cytokines Are Critical for Respiratory Syncytial Virus-Associated Airway Hyperreponsiveness through Regulation by Complement C3a and Tachykinins (2011)

Respiratory syncytial virus (RSV) infection is associated with serious lung disease in infants and immunocompromised individuals and is linked to development of asthma. In mice, acute RSV infection causes airway hyperresponsiveness (AHR), inflammation, and mucus hypersecretion. Infected cells induce complement activation, producing the anaphylatoxin C3a. In this paper, we show RSV-infected wild-type mice produce Th17 cytokines, a response not previously associated with viral infections. Mice deficient in the C3aR fail to develop AHR following acute RSV infection, and production of Th17 cytokines was significantly attenuated. Tachykinin production also has been implicated in RSV pathophysiology, and tachykinin receptor-null mice were similarly protected from developing AHR. These animals were also deficient in production of Th17 cytokines. Tachykinin release was absent in mice deficient in C3aR, whereas C3a levels were unchanged in tachykinin receptor-null animals. Thus, our data reveal a crucial sequence following acute RSV infection where initial C3a production causes tachykinin release, followed by activation of the IL-17A pathway. Deficiency of either receptor affords protection from AHR, identifying two potential therapeutic targets.

Longitudinal Scarring in Severe Colonic Crohnʼs Disease Treated with Anti-Mycobacterium avium SS Paratuberculosis (MAP) Therapy (2006)

Purpose: Mycobacterium avium ss paratuberculosis (MAP) causes Johne's disease in animals, and is implicated as the pathogen of Crohn's disease (CD) in humans. In our clinical experience using anti-MAP to treat CD patients, a novel healing pattern was observed. This review is to report the unusual healing pattern demonstrated by patients with severe colonic CD when treated with anti-MAP therapy. Methods: A retrospective review of 52 patients with severe colonic CD was conducted. Of these, 41 (21M, 20F; 15–75y) had at least one follow-up colonoscopy during the course of treatment and thus were included in the review. Patients received rifabutin (up to 600mg/d), clofazimine (up to 100mg/d) and clarithromycin (up to 1g/d) for between 6mths and 9yrs. A ramp-up dosing schedule was used. Patients underwent colonoscopies at intervals to monitor progress. Photographs of mucosa were taken pre- and during treatment. Histology was monitored throughout treatment. Results: Visual Appearance: Twenty two of 41 (53.7%) demonstrated unusual scarring whilst on anti-MAP therapy. Scarring was not observed in any patient before commencing therapy. Scars only developed once inflamed mucosa began to heal. Longitudinal scars appeared as branched, elevated white lines. Eleven patients had ≥3yrs of treatment following the appearance of scarring. In 2/11 patients (18.2%), scars began to recede after this time, becoming virtually imperceptible as the mucosa fully healed. Histology: All 41 patients demonstrated histologically active CD before commencing anti-MAP therapy. At 1–9yrs of therapy (mean = 3.2 years), an improvement in the severity of mucosal inflammation was seen in 16/41 patients (39.0%). Of these, mucosa returned to normal in 7/16 (43.7%). Ten of the 16 patients with improved histology also demonstrated longitudinal scarring. Conclusions: 1. The presence of scarring, fading to normal mucosa may be indicative of a more profound healing on anti-MAP therapy than is seen with standard immunosuppressants, as longitudinal scarring is not found in even rigidly controlled Crohn's treated with standard immunosuppressants. 2. Histology generally returns to normal when patients exhibit scarring on anti-MAP therapy. 3. The progressive nature of this healing and consequent scarring suggests that this may be ‘full thickness’ healing. 4. If true, the aim of all Crohn's therapies should be longitudinal scarring and normal histology.
Role of p85 subunit of phosphatidylinositol-3-kinase as an adaptor molecule linking the insulin receptor, p62, and GTPase-activating protein. (1994)

After insulin stimulation of rat HTC hepatoma cells overexpressing normal human insulin receptors (IR), an antiserum to the p85 subunit of phosphatidylinositol-3-kinase (PIK) (alpha-p85) immunoprecipitated three major tyrosine-phosphorylated proteins: IR, insulin receptor substrate-1 (IRS-1), and a new 62-kDa protein (p62). Studies with antibodies to GTPase activating protein (alpha-GAP) and p62 GAP-associated protein suggested that p62 was the same as (or closely related to) p62 GAP-associated protein. In order to understand how p62 interacts with p85, we employed: 1) antibodies to the p110 subunit of PIK (alpha-p110); and 2) antiserum to IRS-1. To determine which subunit of PIK (p110 or p85) p62 associates with, we first immunoprecipitated insulin-treated cell lysates with alpha-p110 and subsequently immunoprecipitated with alpha-p85 followed by Western blotting analysis with anti-phosphotyrosine antibody (alpha-PY). In response to insulin, most of the tyrosine-phosphorylated p62 was complexed to p85 alone rather than with the PIK heterodimer. Moreover, p62 was absent in alpha-IRS-1 immunoprecipitates. These data suggest that: 1) p62 GAP-associated protein is tyrosine phosphorylated after insulin stimulation of cells; 2) p62 and IRS-1 form separate complexes with p85; 3) p62-GAP complex may be linked to p85 that is not bound to p110; 4) p85 may serve as an adaptor molecule in insulin receptor signaling, interacting with and regulating other intracellular proteins via SH2 domains.
Prediction of convergence dynamics of design performance using differential recurrent neural networks (2008)

Computational fluid dynamics (CFD) simulations have been extensively used in many aerodynamic design optimization problems, such as wing and turbine blade shape design optimization. However, it normally takes very long time to solve such optimization problems due to the heavy computation load involved in CFD simulations, where a number of differential equations are to be solved. Some efforts have been seen using feedforward neural networks to approximate CFD models. However, feedforward neural network models cannot capture well the dynamics of the differential equations. Thus, training data from a large number of different designs are needed to train feedforward neural network models to achieve reliable generalization. In this work, a technique using differential recurrent neural networks has been proposed to predict the performance of candidate designs before the CFD simulation is fully converged. Compared to existing methods based on feedforward neural networks, this approach does not need a large number of previous designs. Case studies show that the proposed method is very promising.
Model Systems for Assessing Cognitive Function: Implications for HIV-1 Infection and Drugs of Abuse (2006)

Memory deficits are common among drug abusers and in those with chronic neurodegenerative disorders. Currently, the mechanisms through which diverse neurophysiologic processes alter memory are not known. This review describes the current systems and rationale for studying memory formation, consolidation, and recall. Special attention is given to physiologic (hippocampal long-term potentiation) and behavioral animal models. The principles and methods described can be applied to studies of diverse clinical disorders.

No Evidence of a Mild Form of Inhalational Bacillus anthracis Infection During a Bioterrorism-Related Inhalational Anthrax Outbreak in Washington, D.C., in 2001 (2005)

These data suggest that a mild form of inhalational anthrax did not occur and that surveillance for moderate or severe illness was adequate to identify all inhalational anthrax cases resulting from the Washington, D.C., bioterrorism-related anthrax exposures.
Design and technology interaction beyond 32nm (2011)

Iterative MAP multiuser detection for constant modulus constellations in synchronous CDMA (2004)

The paper generalizes our previous work on BPSK (Blunt, S.D. and Ho, K.C., Proc. IEEE ICASSP, p.2313-16, 2002) to multiuser detection for constant modulus constellations in synchronous CDMA communication systems based on maximum a posteriori (MAP) estimation. The known finite alphabet of discrete transmitted symbols is approximated as a stochastic parameter with Gaussian distributions centered at the true values of the symbol constellation. This allows for the development of a MAP estimator that takes a priori knowledge of the symbol constellation into account in order to improve estimation accuracy. We examine the performance of the proposed algorithm for BPSK, QPSK, and 8PSK and compare the results with other well-known multiuser detection techniques.
High telomerase activity is an independent prognostic indicator of poor outcome in colorectal cancer. (2000)

Telomerase activity and altered telomere length have been extensively studied in many kinds of malignant tumors for clinical diagnostic and/or prognostic utilities. In the present study, we investigated telomerase activity and telomere length in colorectal cancers and noncancerous colonic mucosa specimens in 100 patients between 1991 and 1996. To determine whether the level of telomerase activity or telomere length is a prognostic indicator of patient outcome, we followed these patients more than 3 years after surgery. Among 100 primary colorectal cancer specimens, 96 specimens had telomerase activity. Because noncancerous mucosa has some detectable telomerase activity, we divided the levels of telomerase activity into three categories: high (>50-fold more than that in noncancerous mucosa); moderate (10- to 50-fold); and low (<10-fold) levels. Among 100 cancer tissues, 28 showed moderate telomerase activity and 44 showed high telomerase activity. The frequency of tumors with moderate or high telomerase activity showed no significant relationship with any clinicopathological factors. The prognosis of the patients with high telomerase activity was significantly worse than that for patients with moderate and low telomerase activity (P < 0.01). Among the 87 patients with curative surgery, disease-free survival rate of those with high telomerase activity was also significantly poorer (P < 0.01). These results indicate that a high level of telomerase activity may be an independent prognosis-predicting factor in the patients with colorectal cancer.
Beampattern-Based Tracking for Millimeter Wave Communication Systems (2016)

We present a tracking algorithm to maintain the communication link between a base station (BS) and a mobile station (MS) in a millimeter wave (mmWave) communication system, where antenna arrays are used for beamforming in both the BS and MS. Downlink transmission is considered, and the tracking is performed at the MS as it moves relative to the BS. Specifically, we consider the case that the MS rotates quickly due to hand movement. The algorithm estimates the angle of arrival (AoA) by using variations in the radiation pattern of the beam as a function of this angle. Numerical results show that the algorithm achieves accurate beam alignment when the MS rotates in a wide range of angular speeds. For example, the algorithm can support angular speeds up to 800 degrees per second when tracking updates are available every 10 ms.
