Multi-modal Scene Reconstruction using Perceptual Grouping Constraints (2006)

In this work we propose a scheme integrating perceptual grouping into stereopsis to reduce the ambiguity of those early processes. We propose a simple perceptual grouping algorithm that - in addition to the geometric information makes use of a novel multi-modal affinity measure between local primitives. We then use this group information to 1) disambiguate the stereopsis by enforcing that stereo matches preserve groups; and 2) correct the reconstruction error due to the image pixel sampling using a linear interpolation over the groups. We show quantitative and qualitative demonstrations of those processes on a variety of sequences.
Back-off efficiency optimization of traveling-wave tubes using simulated annealing (2018)

A simulated annealing approach for delay line optimization is improved and extended to take modulated input signals in back-off operation into account. Envelope simulation in conjunction with CW electron energy distribu­tions are used for efficiency estimation. A Ku-Band helix traveling-wave tube is optimized and results are presented.
Persistent Topology and Metastable State in Conformational Dynamics (2013)

The large amount of molecular dynamics simulation data produced by modern computational models brings big opportunities and challenges to researchers. Clustering algorithms play an important role in understanding biomolecular kinetics from the simulation data, especially under the Markov state model framework. However, the ruggedness of the free energy landscape in a biomolecular system makes common clustering algorithms very sensitive to perturbations of the data. Here, we introduce a data-exploratory tool which provides an overview of the clustering structure under different parameters. The proposed Multi-Persistent Clustering analysis combines insights from recent studies on the dynamics of systems with dominant metastable states with the concept of multi-dimensional persistence in computational topology. We propose to explore the clustering structure of the data based on its persistence on scale and density. The analysis provides a systematic way to discover clusters that are robust to perturbations of the data. The dominant states of the system can be chosen with confidence. For the clusters on the borderline, the user can choose to do more simulation or make a decision based on their structural characteristics. Furthermore, our multi-resolution analysis gives users information about the relative potential of the clusters and their hierarchical relationship. The effectiveness of the proposed method is illustrated in three biomolecules: alanine dipeptide, Villin headpiece, and the FiP35 WW domain.
Oxidation behavior of a patterned TiSi2/polysilicon stack (2001)

The oxidation behavior at the sidewall of patterned TiSi2/polysilicon gate stack has been studied at temperatures from 700 to 850 °C. Oxidation above 800 °C caused an abnormally enhanced oxidation of TiSi2 sidewall, which was not observed in unpatterned TiSi2/polysilicon stack, regardless of the oxidation atmosphere. High-resolution transmission electron microscopy study showed that a SiO2–TiO2 mixture was produced during the enhanced oxidation of TiSi2 film. Lightly doped drain structures with TiSi2/polysilicon gate and nitride spacer were fabricated using gate reoxidation at 750 °C without degradation of sheet resistance.
Learning Dense Rewards for Contact-Rich Manipulation Tasks (2020)

Rewards play a crucial role in reinforcement learning. To arrive at the desired policy, the design of a suitable reward function often requires significant domain expertise as well as trial-and-error. Here, we aim to minimize the effort involved in designing reward functions for contact-rich manipulation tasks. In particular, we provide an approach capable of extracting dense reward functions algorithmically from robots' high-dimensional observations, such as images and tactile feedback. In contrast to state-of-the-art high-dimensional reward learning methodologies, our approach does not leverage adversarial training, and is thus less prone to the associated training instabilities. Instead, our approach learns rewards by estimating task progress in a self-supervised manner. We demonstrate the effectiveness and efficiency of our approach on two contact-rich manipulation tasks, namely, peg-in-hole and USB insertion. The experimental results indicate that the policies trained with the learned reward function achieves better performance and faster convergence compared to the baselines.
Structure of D-Glucosaccharodilactone (1965)

The crystalline dilactone (IV) of D-glucosaccharic acid (I) derived from both 1, 4-lactone (II) and 3, 6-lactone (III) was found to be identical, and its structure was established as 1, 4-3, 6-dilactone. It was confirmed that the rapid mutarotation of IV in aqueous solution was attributable to the instability of its 1, 4-γ-lactone ring.
Data from TLE1 Is an Anoikis Regulator and Is Downregulated by Bit1 in Breast Cancer Cells (2023)

&lt;div&gt;Abstract&lt;p&gt;TLE1 is a Groucho-related transcriptional repressor protein that exerts survival and antiapoptotic function in several cellular systems and has been implicated in the pathogenesis of cancer. In the present study, we found that TLE1 is a regulator of anoikis in normal mammary epithelial and breast carcinoma cells. The induction of apoptosis following loss of cell attachment to the extracellular matrix (anoikis) in untransformed mammary epithelial MCF10A cells was associated with significant downregulation of TLE1 expression. Forced expression of exogenous TLE1 in these cells promoted resistance to anoikis. In breast cancer cells, TLE1 expression was significantly upregulated following detachment from the extracellular matrix. Genetic manipulation of TLE1 expression via overexpression and downregulation approaches indicated that TLE1 promotes the anoikis resistance and anchorage-independent growth of breast carcinoma cells. Mechanistically, we show that TLE1 inhibits the Bit1 anoikis pathway by reducing the formation of the proapoptotic Bit1-AES complex in part through sequestration of AES in the nucleus. The mitochondrial release of Bit1 during anoikis as well as exogenous expression of the cytoplasmic localized Bit1 or its cell death domain induced cytoplasmic translocation and degradation of nuclear TLE1 protein. These findings indicate a novel role for TLE1 in the maintenance of anoikis resistance in breast cancer cells. This conclusion is supported by an immunohistochemical analysis of a breast cancer tissue array illustrating that TLE1 is selectively upregulated in invasive breast tumors relative to noninvasive ductal carcinoma &lt;i&gt;in situ&lt;/i&gt; and normal mammary epithelial tissues. &lt;i&gt;Mol Cancer Res; 10(11); 1482–95. ©2012 AACR&lt;/i&gt;.&lt;/p&gt;&lt;/div&gt;
Large-Scale QoS-Aware Service-Oriented Networking with a Clustering-Based Approach (2007)

Motivated by the fact that most of the existing QoS service composition solutions have limited scalability, we develop a hierarchical-based solution framework to achieve scalability by means of topology abstraction and routing state aggregation. The paper presents and solves several unique challenges associated with the hierarchical-based QoS service composition solution in overlay networks, including topology formation (cluster detection and dynamic reclustering), QoS and service state aggregation and distribution, and QoS service path computation in a hierarchically structured network topology. In our framework, we (1) cluster network nodes based on their Internet distances and maintain clustering optimality at low cost by means of local reclustering operations when dealing with dynamic membership; (2) use data clustering and Bloom filter techniques to jointly reduce complexity of data representation associated with services within a cluster; and (3) investigate a top-down approach for computing QoS service paths in a hierarchical topology.

Temperature sensitivity analysis of system power profiles (2001)

This paper proposes a novel methodology to estimate the impact of temperature rise to the system power consumption. The load survey study is performed to derive the typical load patterns of the residential, commercial, and industrial customer respectively. By analyzing the relationship of customer power consumption and temperature, the temperature sensitivity of power consumption for each customer class is determined. By integrating the typical load patterns and total energy consumption, the daily power profiles and load composition of the Taipower system has been obtained. With the load compositions and temperature sensitivities of all customer classes, the hourly increase of system power loading due to temperature rise is solved. According to the study, the peak loading of the Taipower system will be increased by 585 MW or 2.4% of the system power demand for each 1/spl deg/C temperature rise. The actual Taipower system loading is used to verify the accuracy of the temperature sensitivity solved by the proposed method. It is concluded that the power increase due to temperature rise has been mainly contributed by the usage of air conditioners in the commercial and residential customers.
The Synthesis and Chlorination of Some Pyrimidin-4-ols Having 5-Nitrogen Functionality (1990)

Syntheses of a number of pyrimidin-4-ols having 5-nitrogen functionality are described. Phosphorus oxychloride/diethylaniline chlorination of 6-amino-2-methylthio-5-nitropyrimidin-4-ol gave the corresponding 6-chloro derivative. However, 2-amino-6-methylthio-5-nitropyrimidin-4-ol failed to yield a 4-chloro derivative under the same conditions. Similar chlorination of 2,5-diaminopyrimidine-4,6-diol gave a poor yield of the 4,6-dichloro product but under these conditions 2-amino-5-benzoylaminopyrimidine-4,6-diol* gave 7-chloro-2-phenyloxazolo[5,4-d]pyrimidin-5-amine. 5-Acetylamino-2-methylthiopyrimidine-4,6-diol yielded 7-chloro-2- methyl-5-methylthiooxazolo[5,4-d] pyrimidine as the major product together with some 5-acetylamino-4,6-dichloro-2-methylthiopyrimidine under the same chlorination conditions.
Gait characterization via pulse-Doppler radar (2011)

Falls are a major cause of injury in the elderly with almost 1/3 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rd</sup> of people aged 65 and more falling each year. This work aims to use gait measurements from everyday living environments to estimate risk of falling and enable improved interventions. For this purpose, we consider the use of low-cost pulse-Doppler range control radar. These radars can continuously acquire data during normal activity of a person in night and day conditions and even in the presence of obstructing furniture. A short-time Fourier transform of the radar data reveals unique Doppler signatures from the torso motion and the leg swings. Two algorithms that can extract these features from the radar spectrogram are proposed in this study for estimating gait velocity and stride durations. The performance of the proposed radar system is evaluated with experimental data, which consists of 9 different walk types and a total of 27 separate tests. A high accuracy motion-capture camera system has also been used to acquire data simultaneously with the radar and provides the ground truth reference. Results indicate that the proposed radar system is a viable candidate for gait characterization and can be used to accurately track mean gait velocity, mean stride duration and stride duration variability. The gait velocity variability can also be estimated but with relatively larger error levels.
Deep Tracking: Visual Tracking Using Deep Convolutional Networks (2015)

In this paper, we study a discriminatively trained deep convolutional network for the task of visual tracking. Our tracker utilizes both motion and appearance features that are extracted from a pre-trained dual stream deep convolution network. We show that the features extracted from our dual-stream network can provide rich information about the target and this leads to competitive performance against state of the art tracking methods on a visual tracking benchmark.
Robust particle filters via sequential pairwise reparameterized Gibbs sampling (2012)

Sequential Monte Carlo (“particle filtering”) methods provide a powerful set of tools for recursive optimal Bayesian filtering in state-space models. However, these methods are based on importance sampling, which is known to be non-robust in several key scenarios, and therefore standard particle filtering methods can fail in these settings. We present a filtering method which solves the key forward recursion using a reparameterized Gibbs sampling method, thus sidestepping the need for importance sampling. In many cases the resulting filter is much more robust and efficient than standard importance-sampling particle filter implementations. We illustrate the method with an application to a nonlinear, non-Gaussian model from neuroscience.
Structure and dielectric properties of a thermoplastic blend containing dispersed metal (2003)

Abstract In the present work broadband dielectric relaxation spectroscopy measurements were employed to investigate the dielectric properties of polymer composites. A polyethylene/polyoxymethylene (PE/POM) thermoplastic blend was used as a matrix, while the inclusions were iron (Fe) particles. For comparison, the two pure polymers‐ PE and POM‐ were used as a matrix, too. In the PE/POM‐Fe composites, the polymer matrix is two‐phase and the filler particles are localized only in the POM phase, resulting in an ordered distribution of the dispersed filler particles within the blend. In PE‐Fe and POM‐Fe composites, the filler spatial distribution is random. The behaviour of all the composites studied is described in terms of the percolation theory. The PE/POM‐Fe composites, based on the PE/POM blend, demonstrate different electrical behaviour compared to that of POM‐Fe and PE‐Fe systems. The percolation threshold value of the PE/POM‐Fe composites was found much lower than that of the other two systems. The results were related to the microstructure of the composites. A schematic model for the morphology of the composites studied has been proposed. This model explains the peculiar behaviour of the PE/POM‐Fe composites by taking into account the ordered distribution of the filler particles in a binary polymer matrix. Optical microscopy photographs confirm this model.
Frequency spectrum of the flicker phenomenon in erythrocytes (1975)

Red blood cells show a remarkable flicker phenomenon under physiological conditions. We have studied experimentally the correlations functions G(R12, ω) for the flicker intensities measured at two different points r 1 r2 on the cell surface, at various filtering frequencies ω. We find that the shape of G is universal and involves only one characteristic length λ(ω) varying like ω-n, where 0.12 < n < 0.19. Measurements of G(0, ω) (i.e. at a single point) show an ω-m dependence, where 1.30 < m < 1.45. These results are then interpreted theoretically in term of thermal fluctuations of the cell thickness. In physiological conditions the membrane surface tension vanishes exactly and the resistance to deformation is mainly due to curvature energy. In this approximation : a) the fluctuations are of very large amplitude (a fraction of a micron) as required by the observations ; b) the detailed shape of the correlations is in rather good agreement with the theory ; c) the scaling length λ(ω) is expected to vary like ω-1/6; d) the single point spectrum G(0, ω) should go like ω-4/3. The approximation involves the neglect of some non linear effects related to surface tension and to the Evans elastic energy. We show that the inclusion of non linear terms leads to a problem related to the critical point of a (special) two dimensional magnetic system. Our approximation (equivalent to a mean field theory) essentially ignores the exponent correction η introduced by Fisher for phase transitions. Thus, the experimental evidence favours a rather small η. We conclude that a purely physical interpretation of the flicker effect is sufficient, but that rather stringent physiological conditions are required to maintain the zero surface tension which is crucial to the effect.
Study of Apoptosis Induction and Deoxycytidine Kinase/Cytidine Deaminase Modulation in the Synergistic Interaction of a Novel Ceramide Analog and Gemcitabine in Pancreatic Cancer Cells (2010)

This study investigated the interaction between the novel ceramide analog AL6 and gemcitabine in MIA PaCa-2 and PANC-1 pancreatic cancer cell lines, harboring different polymorphic variants of the gemcitabine catabolism enzyme cytidine deaminase (CDA). AL6 dose-dependently inhibited cell growth, induced apoptosis and synergistically enhanced the cytotoxic activity of gemcitabine. Moreover, it triggered apoptosis, which was significantly enhanced by the combination, and increased the ratio between gene expression of the activating enzyme deoxycytidine kinase (dCK) and CDA, potentially favoring gemcitabine activity. In conclusion, AL6 displays synergistic cytotoxic activity, enhances apoptosis, and favorably modulates enzymes involved in gemcitabine metabolism, supporting future investigation of this combination in pancreatic cancer.
New roles for systemic retinoids. (2006)

Acitretin, the only oral retinoid indicated for the treatment of psoriasis, has shown activity when used in combination, rotational, and sequential therapy regimens with other therapies. When used with phototherapy, significantly greater activity has been observed at lower doses than with either approach as monotherapy. While initial anecdotal evidence is promising, clinical trials are needed to evaluate whether sequential or rotational use of biologic agents with acitretin may yield improved efficacy and an acceptable safety profile with decreased risk of immunosuppression. Acitretin and other retinoids also work as chemopreventative agents in psoriasis patients with extensive exposure to psoralen ultraviolet A (PUVA) and in solid-organ transplant patients where a number of studies have reported decreased numbers of squamous cell cancers when treated with acitretin.

Development and Evaluation of a Tie-Down System for the Redesigned F-Shape Concrete Temporary Barrier (2003)

Often, temporary barriers are used in applications where it is desired that their deflection during vehicular impact be limited. One such application is in the installation of temporary barriers placed adjacent to the edge of a concrete bridge deck in order to maximize lane width. Acceptable tie-down systems for temporary barriers have previously been developed, but there are concerns when the barriers and tie-down systems are used on bridges that are reconstructed in stages and where very little tolerance in barrier deflection is allowable. Therefore, a rigid tie-down system was developed that minimizes barrier deflections. For this system, the original Kansas temporary barrier was redesigned in order to strengthen the barrier around the tie-down holes and to standardize the barriers for use in adjacent states and in various temporary and tied-down configurations. The tie-down anchor system fastened the traffic-side of the barriers to the concrete bridge deck with three 29-mm (1.125-in.) diameter ASTM A307 anchor bolts with heavy hex nuts and 76-mm (3-in.) x 76-mm (3-in.) x 13-mm (0.5-in.) thick washers. The research study included one full-scale vehicle crash test, using a 3⁄4-ton pickup truck. The full-scale test, with an impact speed of 99.8 km/hr (62.0 mph) and an impact angle of 25.3 degrees, was conducted and reported in accordance with the requirements specified in the National Cooperative Highway Research Program (NCHRP) Report No. 350, Recommended Procedures for the Safety Performance Evaluation of Highway Features. The safety performance of the tie-down anchor system for use with concrete bridge decks and the redesigned F-shape temporary concrete barrier was determined to be acceptable according to the Test Level 3 (TL-3) evaluation criteria specified in NCHRP Report No. 350.
Friction stir welding of DH36 steel (2003)

Hot rolled DH36 carbon steel, 6.4 mm in thickness, was friction stir welded at speeds of 3.4 mm s -1 (8 in min -1 ), 5.1 mm s -1 (12 in min -1 ), and 7.6 mm s -1 (18 in min -1 ). Single pass welds free of volumetric defects were produced at each speed. The relationships between welding parameters and weld properties are discussed. Optical microscopy, microhardness testing, and transverse and longitudinal tensile tests have been performed. Bainite and martensite are found in the nugget region of the friction stir welds whereas the base material is comprised of ferrite and pearlite. The maximum hardness is observed in the weld nugget, and the hardness decreases gradually from the weld nugget, through the heat affected zone, to the base metal. Tensile testing also indicates overmatching of the weld metal relative to the base metal. Maximum hardness and longitudinal (all weld metal) tensile strengths increase with increasing welding speeds. Weld transverse tensile strengths are governed by the base metal properties, as all transverse tensile bars fail in the base metal.
