Pancam Mast Assembly on Mars Rover (2004)

The Pancam Mast Assembly (PMA) for the 2003 Mars Rover is a deployable structure that provides an elevated platform for several cameras. The PMA consists of several mechanisms that enable it to raise the cameras as well as point the cameras in all directions. This paper describes the function of the various mechanisms as well as a description of the mechanisms and some test parameters. Designing these mechanisms to operate on the surface of Mars presented several challenges. Typical spacecraft mechanisms must operate in zero-gravity and high vacuum. These mechanisms needed to be designed to operate in Martian gravity and atmosphere. Testing conditions were a little easier because the mechanisms are not required to operate in a vacuum. All of the materials are vacuum compatible, but the mechanisms were tested in a dry nitrogen atmosphere at various cold temperatures.
Representing Contiguity in Page Table for Memory Management Units (2017)

Conventional page based memory management schemes have certain overheads related to system performance and memory utilization mainly due to page table walks. In addition, the conventional translation look-aside buffers often suffer from the limited capacity. To reduce these problems, we propose an efficient scheme that accommodates the contiguity information in a page table. The presented memory management unit exploits the contiguity information. As a result, we can reduce the page table walks as certain physical memory is allocated in the contiguous way. Considering the conventional scheme as a reference, the comparative performance analysis and the simulation are conducted. Experiments with image processing applications indicate that the proposed scheme can significantly improve the system performance, the memory utilization, and the utilization of a translation look-aside buffer.
A charge-polarized porous metal–organic framework for gas chromatographic separation of alcohols from water (2013)

A bipyridinium ligand with a charge separated skeleton has been introduced into a metal-organic framework to yield a porous material with charge-polarized pore space, which exhibits selective adsorption for polar guest molecules and can be further used in gas chromatography for the separation of alcohol-water mixtures.
Robot Imitation: Body Schema and Body Percept (2005)

There are two functional elements used by humans to understand and perform actions. These elements are: the body schema and the body percept. The first one is a representation of the body that contains information of the body's capabilities. The second one is a snapshot of the body and its relation with the environment at a given instant. These elements interact in order to generate, among other abilities, the ability to imitate. This paper presents an approach to robot imitation based on these two functional elements. Our approach is gradually expanded throughout three developmental stages used by humans to refine imitation. Experimental results are presented to support the feasibility of the proposed approach at the current stage for 2D movements and simple manipulation actions.
ZnO/Au Hybrid Nanoarchitectures: Wet-Chemical Synthesis and Structurally Enhanced Photocatalytic Performance (2009)

A facile method is introduced to prepare large-area gold-coated ZnO nanorods, featuring the capability to tailor both the spatial distribution and the concentration of metal nanocrystals. The Au nanoparticles-loaded ZnO nanorods exhibit complete catalysis-degradation Rhodamine B within 15 min, which substantially surpass other TiO(2)- and ZnO-based photocatalysts. Furthermore, The ZnO/Au nanocomposites can removal about 91% of environmental persistent 4-chlorophenol from water after 300 min irradiation. The better photocatalytic performance is attributed to the one-dimentional structure of high-quality ZnO nanorods and the large-area noble metal decoration. These promising results would make this photocatalyst an exceptional choice for the environmental purification of organic pollutants in aqueous solution. This approach may also give rise to a new class of multifunctional materials with possible applications in energy-conversion devices, biofunctionalized materials, and infrared-emitting/detecting devices.
Stiffness properties for Nucleus standard straight and contour electrode arrays (2004)

Trauma and damage during insertion of electrode arrays into the human cochlea are strongly related to the stiffness of the array. The stiffness properties of electrode arrays, which were determined by three-point flexural bending and buckling tests, are reported in this paper. To date there has been limited publication on mechanical properties of these electrode arrays. Previous studies mainly focused on characterizing the stiffness of the tip of the Nucleus straight array with little emphasis on characterizing the stiffness of its whole length. In this study, stiffnesses of the Nucleus straight and contour electrode arrays have been determined along their length. Young's modulus of elasticity of the Nucleus straight array has been found to increase from the tip (182 MPa) to the rear end (491 MPa), whereas the stiffness of the contour array is greatest near the tip (480 MPa) and is fairly uniform in the middle and rear sections of the electrode array (380-400 MPa). Buckling experiments have shown that the contour array has much higher critical buckling load (about four times) than the Nucleus straight array. The results from three-point flexural bending and buckling experiments provide significant data for the development of electrode arrays, from which new array designs with improved flexibility can be developed. The results of stiffness properties are also important input for use in finite element models to predict the trajectories during insertion and to help evaluate the effects of different electrode array designs on damage sustained during insertion.
Mannose-Binding Lectin in Susceptibility and Progression of HIV-1 Infection in Children (2006)

MBL deficiency was more frequent in patients with severe disease as assessed by CD4+ T-cell status. MBL-2 variants may be less frequent in children classified as LTNPs. MBL analysis could be useful in identifying children with slow disease progression and, consequently, may not require immediate antiretroviral treatement.
IL‐23 and IL‐17 have a multi‐faceted largely negative role in fungal infection (2007)

The role of IL-23 and IL-17 in the response to fungal infection has been the focus of recent reports. In this issue of the European Journal of Immunology there is an article that reports an important role for IL-23 and IL-17 in limiting fungal control, promoting neutrophillic inflammation and regulating the killing activity of neutrophils. In the fungal model it appears that IL-23 and IL-17 are counter-productive for protection.
Light‐trap Catches of Fruit Tortricid Moths in Kent, 1964–74, and Associated Temperature Sums (1978)

SUMMARY Light‐trap catches of five tortricid species were recorded at orchard sites in Kent over an 11‐year period. The dates on which moths of Hedya nubiferana (Haw.), Cydia pomonella (L.) and Archips podana (Scop.) were caught in light traps were strongly correlated with accumulated temperatures in day‐degrees above a base of 8°C. The correlation was less good for catches of Pandemis heparana (Denis & Schiff.) and it was slightly better for those of Cydia pomonella above 10°C than above 8°C. The data were insufficient to calculate temperature sums for catches of Adoxophyes orana (Fisch. v. Rösl.). Moth catches of all five species showed differences between years in the timing of first and second generations. The dates of first catches are compared with dates estimated from the following temperature sums: for H. nubiferana 226 day‐degrees above 8°C, for C. pomonella 268 day‐degrees above 8°C and 149 day‐degrees above 10°C, for Archips podana 326 day‐degrees above 8°C and for P. heparana 386 day‐degrees above 8°C. In the 11‐year period, estimated dates of first catch were within ± 5 days of first actual catch of moths in light traps in nine years for C. pomonella , eight years for H. nubiferana and A. podana , but only five years for P. heparana.
An investigation of GaAs MMIC high power limiters for circuit protection (2002)

In this paper, we present an investigation of GaAs MMIC semiconductor limiters which can be fabricated on a standard MMIC process. This investigation, which included high power vector measurements of S-parameters over lime, led to the design of a highly compact limiter integrated directly onto an FM-CW radar MMIC. As we demonstrate, the limiter significantly improved the lifetime of the FM-CW radar MMIC when exposed to both single and multiple short, high power pulses of microwave energy.
Throughput constrained and area optimized dataflow synthesis for FPGAs (2008)

Although high-level synthesis has been researched for many years, synthesizing minimum hardware implementations under a throughput constraint for computationally intensive algorithms remains a challenge. In this thesis, three important techniques are studied carefully and applied in an integrated way to meet this challenging synthesis requirement. The first is pipeline scheduling, which generates a pipelined schedule that meets the throughput requirement. The second is module selection, which decides the most appropriate circuit module for each operation. The third is resource sharing, which reuses a circuit module by sharing it between multiple operations. This work shows that combining module selection and resource sharing while performing pipeline scheduling can significantly reduce the hardware area, by either using slower, more area-efficient circuit modules or by time-multiplexing faster, larger circuit modules, while meeting the throughput constraint. The results of this work show that the combined approach can generate on average 43% smaller hardware than possible when a single technique (resource sharing or module selection) is applied. There are four major contributions of this work. First, given a fixed throughput constraint, it explores all feasible frequency and data introduction interval design points that meet this throughput constraint. This enlarged pipelining design space exploration results in superior hardware architectures than previous pipeline synthesis work because of the larger sapce. Second, the module selection algorithm in this work considers different module architectures, as well as different pipelining options for each architecture. This not only addresses the unique architecture of most FPGA circuit modules, it also performs retiming at the high-level synthesis level. Third, this work proposes a novel approach that integrates the three inter-related synthesis techniques of pipeline scheduling, module selection and resource sharing. To the author's best knowledge, this is the first attempt to do this. The integrated approach is able to identify more efficient hardware implementations than when only one or two of the three techniques are applied. Fourth, this work proposes and implements several algorithms that explore the combined pipeline scheduling, module selection and resource sharing design space, and identifies the most efficient hardware architecture under the synthesis constraint. These algorithms explore the combined design space in different ways which represents the trade off between algorithm execution time and the size of the explored design space.
Spatial Updating Depends on Gaze Direction Even after Loss of Vision (2012)

Direction of gaze (eye angle + head angle) has been shown to be important for representing space for action, implying a crucial role of vision for spatial updating. However, blind people have no access to vision yet are able to perform goal-directed actions successfully. Here, we investigated the role of visual experience for localizing and updating targets as a function of intervening gaze shifts in humans. People who differed in visual experience (late blind, congenitally blind, or sighted) were briefly presented with a proprioceptive reach target while facing it. Before they reached to the target's remembered location, they turned their head toward an eccentric direction that also induced corresponding eye movements in sighted and late blind individuals. We found that reaching errors varied systematically as a function of shift in gaze direction only in participants with early visual experience (sighted and late blind). In the late blind, this effect was solely present in people with moveable eyes but not in people with at least one glass eye. Our results suggest that the effect of gaze shifts on spatial updating develops on the basis of visual experience early in life and remains even after loss of vision as long as feedback from the eyes and head is available.
Monoclonal Antibody to Human Cytotrophoblast (1984)

A monoclonal antibody (18B/A5) has been generated against human first trimester trophoblast membranes which, unlike others so far reported in the literature, reacted only with cytotrophoblast and not with syncytiotrophoblast. Although the identity of the target antigen has not yet been established, the antibody could be a valuable tool for the identification and eventual separation and purification of human cytotrophoblast cells.
Fully Homomorphic Encryption Using Hidden Ideal Lattice (2013)

All the existing fully homomorphic encryption schemes are based on three different problems, namely the bounded distance decoding problem over ideal lattice, the approximate greatest common divisor problem over integers, and the learning with error problem. In this paper, we unify the first two families of problems by introducing a new class of problems, which can be reduced from both problems. Based on this new problem, namely the bounded distance decoding over hidden ideal lattice, we present a new fully homomorphic encryption scheme. Since it is a combination of the two problems to some extent, the performance of our scheme lies between the ideal lattice based schemes and the integer based schemes. Furthermore, we also show a lower bound and upper bound of the problem that our scheme is based on. Assuming this security conjecture holds, we can incorporate smaller parameters, which will result in a scheme that is more efficient than both lattice based and integer based schemes. Hence, our scheme makes a perfect alternative to the state-of-art ring learning with error based schemes.
"Nuevo laboratorio de bioseguridad: una respuesta a la globalización y al control de las enfermedades infecciosas en Sinaloa" (2010)

La globalizacion plantea constantemente nuevos retos para la salud publica. Uno muy importante es el control de las enfermedades transmisibles. La rapidez y frecuencia de la diseminacion de agentes patogenos a partir de diversas fuentes potenciales de transmision como los seres humanos, animales, alimentos etc. estan asociadas entre otras cosas al flujo migratorio y comercial que han puesto al descubierto la vulnerabilidad de la infraestructura cientifico-tecnologica de los paises en desarrollo para enfrentar desafios, como la reciente pandemia de influenza, frente a la que solo algunos paises estuvieron preparados y practicamente en todo el mundo se tuvieron serias dificultades para realizar los ensayos de laboratorio para el diagnostico oportuno y eficiente de la enfermedad. En respuesta a esta problematica, en Sinaloa contamos con un laboratorio de bioseguridad nivel 2 que permite el manejo especializado para la identificacion, diagnostico e investigacion de agentes infecciosos con elevado potencial de virulencia causantes de enfermedades potencialmente letales para los seres humanos como influenza A H1N1 pandemica, gripe aviar, SIDA y dengue. Esta nueva infraestructura esta ubicada en la ciudad de Culiacan, en las instalaciones del Laboratorio Estatal de Salud Publica de Sinaloa y se trata de una de las primeras en su tipo en Mexico
Non-Hermitian Degeneracies and Unidirectional Reflectionless Atomic Lattices (2014)

Light propagation in optical lattices of driven cold atoms exhibits non-Hermitian degeneracies when the first-order modulation amplitudes of real and imaginary parts of the probe susceptibility are manipulated to be balanced. At these degeneracies, one may observe complete unidirectional reflectionless light propagation. This strictly occurs with no gain and can be easily tuned and fully reversed as supported by the transfer-matrix calculations and explained via a coupled-mode analysis.
A new method for the evaluation of antibody affinity based on serial dilutions of studied antibody-antigen mixture. (2003)

A new method for the evaluation of the affinity of bivalent antibodies were suggested. This method is based on the previously published by the author the idea of using so-called coordinates of dilutions. It was shown that the suggested method allows to evaluate the affinity of antibodies with high accuracy using this simple approach. It is supposed that at some conditions the suggested method could have substantial advantages in comparison to the traditional methods. This method allows to analyze situations when antibodies are already in a mixture with antigen, for example in the bloodstream in the case of infections or autoimmune diseases. The method provides useful approach for the evaluation not only antibody affinity, but also the concentration of circulated antigen.

Color demosaicking by local directional interpolation and nonlocal adaptive thresholding (2011)

Single sensor digital color cameras capture only one of the three primary colors at each pixel and a process called color demosaicking (CDM) is used to reconstruct the full color images. Most CDM algorithms assume the existence of high local spectral redundancy in estimating the missing color samples. However, for images with sharp color transitions and high color saturation, such an assumption may be invalid and visually unpleasant CDM errors will occur. In this paper, we exploit the image nonlocal redundancy to improve the local color reproduction result. First, multiple local directional estimates of a missing color sample are computed and fused according to local gradients. Then, nonlocal pixels similar to the estimated pixel are searched to enhance the local estimate. An adaptive thresholding method rather than the commonly used nonlocal means filtering is proposed to improve the local estimate. This allows the final reconstruction to be performed at the structural level as opposed to the pixel level. Experimental results demonstrate that the proposed local directional interpolation and nonlocal adaptive thresholding method outperforms many state-of-the-art CDM methods in reconstructing the edges and reducing color interpolation artifacts, leading to higher visual quality of reproduced color images.
Farmland Quality Evaluation Based on GIS and Fuzzy Matter-Element Proximity Cluster Model (2008)

With the original data as basis, evaluation of cultivated land quality was carried out in Yidu County with the aid of GIS and the fuzzy matter-element proximity cluster model. The procedure of the evaluation goes:(1)Use the principal component analysis method to determine factors which affecting cultivated land quality;(2) extract correlatographs through vectorization with the aid of ArcGIS, put them under spatial analysis, and overlay multi-maps to define evaluation units and extract attribute data; (3) based on membership functions of evaluation factors and fuzzy matter-element proximity cluster analysis model, calculate weight of evaluation factors and proximity of evaluation units, then sort the cultivated lands into various quality levels. At the same time, 120 samples were collected randomly to verify veracity of the results. The results indicate that the quality of cultivated land in this area is medium in Hubei Province and can be sorted into 6 levels, accounting for 12.96%, 30.37%, 31.71%, 16.16%, 7.14% and 1.66%, respectively, which is in accord with the actual situation.
Machining characterization of the nano-lithography process using atomic force microscopy (2000)

The machining characteristics of nano-lithography are studied using atomic force microscopy (AFM). Scribing (scratching) experiments containing reciprocal single line furrows and multiple furrows are conducted to investigate the influence of the working parameters on the machined surface's properties, and upon the machining efficiency. The influence of the working parameters, including the applied load on the cantilever, scribing cycles, scribing speed and scribing feed, on the surface roughness, surface depth and material removal rate can then be accessed. Results indicate that the applied load is more significant than the scribing cycles on the groove depth. However, rougher surfaces are produced at larger loads. In multiple furrows produced with larger applied loads in order to obtain deeper furrows, surface roughness is improved by adjusting the scribing feed to a small value.
Swarming over the software barrier (1991)

Swarm is a concurrent programming model which integrates a Linda-like communication medium, the shared dataspace, with a UNITY-like computational model, proof system, and program structure. It generalizes the Linda tuple-space operations by providing more powerful dataspace queries. It generalizes UNITY by permitting content-based access to data, a dynamic set of statements, and the capability to control the execution mode (i.e., synchronous or asynchronous) for arbitrary collections of program statements.

A Room Temperature 0.1 /spl mu/m CMOS on SOI (1993)

An advanced 0.1 /spl mu/m CMOS technology on SOI is presented. In order to minimize short channel effects, relatively thick non- delpleted (0.1 /spl mu/m) SOI film, highly non-uniforin channel doping and source-drain extension-HALO were used. Excellent short channel effects (SCE) down to channel lengths below 0.1 /spl mu/m were obtained. Very high speeds were obtained: Unloaded delay was 20 psec, and fully loaded NAND (FI=FO=3, CL-0.3 pF) delay was 130 psec at supply of 1.8 V.
Traceback Attacks in Cloud -- Pebbletrace Botnet (2012)

Botmaster sets up Command and Control (C&C) server and stepping-stones in the Internet for stealing sensitive information from victim's machine. Clouds provide botmaster with an ideal environment of rich computing resources where he can easily deploy/remove C&C server and establish/tear-down stepping-stones for anonymous attacks. It is of vital importance for cloud service providers to detect botnet, prevent attack, and trace back to the botmaster. We present our Pebble trace scheme for the trace back to the botmaster. It first identifies cryptographic keys of the botnet communications for configuring botnet operations and then traces back to the botmaster. We design and implement a new key identification scheme and propose an approach for tracing back to the botmaster across stepping-stones and beyond multiple clouds without universal deployment of monitors, router updates, or ISP support. We implement our method and build a Pebble-trace prototype that is applied to Zeus botnet in OpSource cloud with promising results.
Optical chemical sensing employing surface plasmon resonance (1988)

An optical sensor based on the phenomenon of light-excited surface plasmon resonance has been investigated to measure liquid chemical concentrations. A white light source is used to excite surface plasmon waves at a metal/analyte interface. The wavelength of maximum absorption in the reflected light depends uniquely on the refractive index of the analyte.
