3D particle-based cell modelling for haptic microrobotic cell injection (2011)

\n\t\t\t\t\tIntroducing haptic interface to conduct microrobotic intracellular injection has many beneficial implications. In particular, the haptic device provides force feedback to the bio-operator's hand. This paper introduces a 3D particle-based model to simulate the deformation of the cell membrane and corresponding cellular forces during microrobotic cell injection. The model is based on the kinematic and dynamic of spring &amp;ndash; damper multi particle joints considering visco-elastic fluidic properties. It simulates the indentation force feedback as well as cell visual deformation during the microinjection. The model is verified using experimental data of zebrafish embryo microinjection. The results demonstrate that the developed cell model is capable of estimating zebrafish embryo deformation and force feedback accurately.\n\t\t\t\t
Detecting Changes in the Relative Expression of KRAS2 Splice Variants Using Polymerase Colonies (2004)

Because splice variants of a gene with multiple isoforms give rise to proteins with different functions, it seems plausible that changes in the expression levels of the splice variants could be a contributing factor to disease. In fact, recent examples in the literature clearly illustrate that altered expression levels of splice variants may play an important role in disease. Furthermore, these works demonstrate that changes in expression levels could potentially be used to (1) monitor disease progression, (2) diagnose disease, and/or (3) determine disease state. In this work an immobilized form of PCR, known as polony technology, was adapted to quantify the relative expression levels of splice variants. Specifically, the relative expression levels of the two splice variants of the oncogene K-ras, namely, K-RAS2A and K-RAS2B, were determined using polony technology.
Measurement of IC package shielding effectiveness using an integrated antenna (2000)

A novel technique for measuring integrated circuit (IC) package shielding effectiveness is presented. The technique is based on radiated field measurements performed with an integrated circuit antenna in a Gigahertz transverse electromagnetic (GTEM) cell. A thorough test procedure which takes into account all possible field contributions is proposed. The technique is simple to implement, cost effective, and suitable for characterizing IC package shielding effectiveness up to 10 GHz.
Carotenoid Derivates in Achiote (Bixa orellana) Seeds: Synthesis and Health Promoting Properties (2016)

<i>Bixa orellana</i> (family Bixaceae) is a neotropical fast growing perennial tree of great agro-industrial value because its seeds have a high carotenoid content, mainly bixin. It has been used since pre-colonial times as a culinary colorant and spice, and for healing purposes. It is currently used as a natural pigment in the food, in pharmaceutical, and cosmetic industries, and it is commercially known as annatto. Recently, several studies have addressed the biological and medical properties of this natural pigment, both as potential source of new drugs or because its ingestion as a condiment or diet supplement may protect against several diseases. The most documented properties are anti-oxidative; but its anti-cancer, hypoglucemic, antibiotic and anti-inflammatory properties are also being studied. Bixin's pathway elucidation and its regulation mechanisms are critical to improve the produce of this important carotenoid. Even though the bixin pathway has been established, the regulation of the genes involved in bixin production remains largely unknown. Our laboratory recently published <i>B. orellana's</i> transcriptome and we have identified most of its MEP (methyl-D-erythritol 4-phosphate) and carotenoid pathway genes. Annatto is a potential source of new drugs and can be a valuable nutraceutical supplement. However, its nutritional and healing properties require further study.
Improving reservoir conformance using gelled polymer systems. Annual report, September 25, 1994--September 24, 1995 (1996)

The objectives of the research program are to (1) identify and develop polymer systems which have potential to improve reservoir conformance of fluid displacement processes, (2) determine the performance of these systems in bulk and in porous media, and (3) develop methods to predict their performance in field applications. The research focused on four types of gel systems -- KUSP1 systems which contain an aqueous polysaccharide designated KUSP1, phenolic-aldehyde systems composed of resorcinol and formaldehyde, colloidal-dispersion systems composed of polyacrylamide and aluminum citrate, and a chromium-based system where polyacrylamide is crosslinked by chromium(III). Gelation behavior of the resorcinol-formaldehyde systems and the KUSP1-borate system was examined. Size distributions of aggregates that form in the polyacrylamide-aluminum colloidal-dispersion gel system were determined. Permeabilities to brine of several rock materials were significantly reduced by gel treatments using the KUSP1 polymer-ester (monoethylphthalate) system, the KUSP1 polymer-boric acid system, and the sulfomethylated resorcinol-formaldehyde system. The KUSP1 polymer-ester system and the sulfomethylated resorcinol-formaldehyde system were also shown to significantly reduce the permeability to super-critical carbon dioxide. A mathematical model was developed to simulate the behavior of a chromium redox-polyacrylamide gel system that is injected through a wellbore into a multi-layer reservoir in which crossflow between layers is allowed. The model describes gelation kinetics and filtration of pre-gel aggregates in the reservoir. Studies using the model demonstrated the effect filtration of gel aggregates has on the placement of gel systems in layered reservoirs.
Application of real-time power system simulators for testing protective relay system operational characteristics (1999)

Proper protective relay operation is essential for power system reliability. System transient conditions and instrument transformer errors are major causes for relay misoperation. Therefore, relays tests need to include both transient simulation and instrument transformer models. This paper presents two techniques for protective system testing: real-time power system simulator (RTPSS) and playback system. Both systems can simulate transient testing as well as instrument transformers.
Uncertainty Propagation Combining Robust Condensation and Generalized Polynomial Chaos Expansion (2015)

Among probabilistic uncertainty propagation methods, the generalized Polynomial Chaos Expansion (gPCE) has recently shown a growing emphasis. The numerical cost of the non-intrusive regression method used to compute the gPCE coefficient depends on the successive Latin Hypercube Sampling (LHS) evaluations, especially for large size FE models, large number of uncertain parameters, presence of nonlinearities and when using iterative techniques to compute the dynamic responses. To overcome this issue, the regression technique is coupled with a robust condensation method adapted to the Craig-Bampton component mode synthesis approach leading to computational cost reduction without significant loss of accuracy. The performance of the proposed method and its comparison to the LHS simulation are illustrated by computing the time response of a structure composed of several coupled-beams containing localized nonlinearities and stochastic design parameters.
The relationship between molecular parameters and polymer distribution and the ability of a polymer to improve the resilience of cotton fabrics (1973)

Elastic properties are found to be critical parameters for polymers which improve the wrinkle resistance of cotton fabric. Those molecular factors which results in optimum recovery of a polymer film from distortion (i.e., stretching) are shown to be directly related to the ability to improve fabric wrinkle recovery. Further, those molecular factors which inhibit the tendency of a polymer to form ordered structures allow the inherent flexibility of the polymer to be utilized in storing energy of distortion. This energy is then available, if the polymer is properly distributed on the fabric, to help overcome the fabric's frictional resistance to recovery. The most advantageous distribution of polymer is one in which interfiber and interyarn elastic bridges are formed.
Envelope Versus Fine Structure Speech Coding Strategy (2011)

This study shows that there is no difference in speech perception with FSP compared to CIS at an extended frequency spectrum. Therefore, the extended frequency spectrum in the low frequencies might explain a benefit of FSP observed in previous studies.

Research of Optimal Control of Working Power in Electrical Discharge Machining (1975)

Electrical discharge machining is a precise working method for hard metals. The work is shaped into a desired configuration by arc erosion conforming to the configuration of the tool-electrode.The transient arc discharge occurs in a very short discharge gap between the tool-electrode and the work immersed in a liquid insulator (working fluid).In order to keep stable the repeating transient arcs, the tool-electrode has to be fed keeping a constant discharge gap. But the discharge gap cannot be measured directly while the discharge circuit is alive. And so the discharge voltage is measured and feeding the toolelectrode is controlled by an average value of the measured discharge voltage that the discharge gap may gets a constant length. In the optimal state of working, the measured gap voltage is believed to be optimal duty factor of the discharge pulses.An abnormal arc occurs frequently due to debris staying between the tool-electrode and the work under a certain duty factor i.e. a constant working power. Accordingly, as working area or depth is increased for a certain working power, the damage of the work due to abnormal arcs increases.In this research, the authors study a technique to detect the pre-abnormal arc by processing the voltage between the tool-electrode and the work, and propose an optimal controller, which has an optimizing algorithm, for the working power i.e. the duty factor of discharge pulses.

Digital Capability Framework: A Toolset to Become a Digital Enterprise (2016)

This chapter introduces the Digital Capability Framework as a new approach which guides you along the transformation path and supports you to successfully achieve a digital transformation and to become a Digital Enterprise. The foundation for digital transformation requires a complete understanding and holistic analysis of internal and external possibilities, feasibilities, strengths and weaknesses. In order to provide such a holistic view, the Digital Capability Framework integrates the Business Transformation Management Methodology (BTM). The Digital Capability Framework consists of four individual building blocks. It is built on six core Digital Capabilities, which are the foundation of a successful Digital Enterprise. Then it defines Digital Capability Maturity Models, which are used to measure the degree of maturity for each Digital Capability. The maturity models support the analysis of the 'as-is' situation and provide instruments for planning the prospective 'to-be' scenario.
Sensor Signal Conditioning - An IC Designer's Perspective (1991)

The characteristics of analog integrated circuits have been steadily improving over the post decade due at least in part to innovative design techniques. Many of these techniques are quite general in nature and can be applied to a wide variety of circuits. Integrated sensor systems (i.e. sensors and electronics on a single chip or multi-chip hybrids) are good candidates for exploiting such advances in analog integrated circuit design, This paper illustrates by specific examples how the signal conditioning circuitry required by most sensors can benefit from techniques like dynamic offset correction, self-calibration, device averaging, and laser trimming.
Modelling for control of a centrifugal compression system (2004)

The performance and operating range of centrifugal compressors is limited by the occurrence of an aerodynamic instability called surge. This instability can lead to severe damage of the machine due to large mechanical and thermal loads. A way to cope with this instability is active control. In this approach, perturbations are fed back into the flow field in order to modify the dynamics of the compression system. Such techniques can extend the stable operating range towards lower mass flows, which makes the compressor more versatile. See also Figure 1. Furthermore it enables the safe operation of the compressor near the surge point.
Radiosurgical Lesions in the Normal Human Brain 17 Years after Gamma Knife Capsulotomy (1997)

This investigation indicates that a minimum dose of 110 Gy, with the currently used 4-mm collimator, to the edge of the target volume is required to create a lesion. The results prove that gamma knife surgery can be used in functional neurosurgery for producing small permanent lesions in the normal human brain.
Binary stirring (2012)

Unlike library code, whose instruction addresses can be randomized by address space layout randomization (ASLR), application binary code often has static instruction addresses. Attackers can exploit this limitation to craft robust shell codes for such applications, as demonstrated by a recent attack that reuses instruction gadgets from the static binary code of victim applications.
Efficient Video Classification Using Fewer Frames (2019)

Recently, there has been a lot of interest in building compact models for video classification which have a small memory footprint (<1 GB). While these models are compact, they typically operate by repeated application of a small weight matrix to all the frames in a video. For example, recurrent neural network based methods compute a hidden state for every frame of the video using a recurrent weight matrix. Similarly, cluster-and-aggregate based methods such as NetVLAD have a learnable clustering matrix which is used to assign soft-clusters to every frame in the video. Since these models look at every frame in the video, the number of floating point operations (FLOPs) is still large even though the memory footprint is small. In this work, we focus on building compute-efficient video classification models which process fewer frames and hence have less number of FLOPs. Similar to memory efficient models, we use the idea of distillation albeit in a different setting. Specifically, in our case, a compute-heavy teacher which looks at all the frames in the video is used to train a compute-efficient student which looks at only a small fraction of frames in the video. This is in contrast to a typical memory efficient Teacher-Student setting, wherein both the teacher and the student look at all the frames in the video but the student has fewer parameters. Our work thus complements the research on memory efficient video classification. We do an extensive evaluation with three types of models for video classification, viz., (i) recurrent models (ii) cluster-and-aggregate models and (iii) memory-efficient cluster-and-aggregate models and show that in each of these cases, a see-it-all teacher can be used to train a compute efficient see-very-little student. Overall, we show that the proposed student network can reduce the inference time by 30% and the number of FLOPs by approximately 90% with a negligent drop in the performance.

Proteomic Analysis of Disease Stratified Human Pancreas Tissue Indicates Unique Signature of Type 1 Diabetes (2015)

Type 1 diabetes (T1D) and type 2 diabetes (T2D) are associated with functional beta cell loss due to ongoing inflammation. Despite shared similarities, T1D is an autoimmune disease with evidence of autoantibody production, as well as a role for exocrine pancreas involvement. Our hypothesis is that differential protein expression occurs in disease stratified pancreas tissues and regulated proteins from endocrine and exocrine tissues are potential markers of disease and potential therapeutic targets. The study objective was to identify novel proteins that distinguish the pancreas from donors with T1D from the pancreas from patients with T2D, or autoantibody positive non-diabetic donors. Detailed quantitative comprehensive proteomic analysis was applied to snap frozen human pancreatic tissue lysates from organ donors without diabetes, with T1D-associated autoantibodies in the absence of diabetes, with T1D, or with T2D. These disease-stratified human pancreas tissues contain exocrine and endocrine tissues (with dysfunctional islets) in the same microenvironment. The expression profiles of several of the proteins were further verified by western blot. We identified protein panels that are significantly and uniquely upregulated in the three disease-stratified pancreas tissues compared to non-disease control tissues. These proteins are involved in inflammation, metabolic regulation, and autoimmunity, all of which are pathways linked to, and likely involved in, T1 and T2 diabetes pathogenesis. Several new proteins were differentially upregulated in prediabetic, T1D, and T2D pancreas. The results identify proteins that could serve as novel prognostic, diagnostic, and therapeutic tools to preserve functional islet mass in Type 1 Diabetes.
Non-linear and adaptive backstepping designs for tracking control of ships (1998)

In this paper two non-linear control laws for ships are derived by using a non-linear ship model which includes the hydrodynamic effects due to time-varying speed and wave frequency. The non-linear ship model does not have the structural properties of symmetric inertia and positive damping at high speed, which are common assumptions, when designing non-linear ship tracking control systems. Backstepping control designs are used to circumvent the problem of a non-symmetrical inertia matrix. The first case is ship tracking with full actuation in surge, sway and yaw while the second case discusses an emergency situation where a ship is supposed to track a time-varying trajectory by using the bow thruster and one of the main propellers as actuation devices only. The application of speed- and wave-dependent models for ship control is a first step towards the design of a new generation of non-linear ship control systems that can operate under time-varying speed and wave frequency conditions. Previous work has often relied on the assumption of constant speed, and practical solutions have been based on switching between different control schemes at different speeds. Slowly varying environmental disturbances, such as ocean current, second-order wave-induced disturbances and wind forces, are compensated for by using adaptive backstepping. Global uniform asymptotic stability (GUAS) is proven for the fully actuated case by using a recent theorem for GUAS when backstepping with integral action, whereas asymptotic tracking of position and velocity are shown for the degraded control case. Computer simulations illustrate the performance and the robustness of the control laws for an offshore supply vessel. © 1998 John Wiley & Sons, Ltd.

Quantum Dots-Based All-Optical-Readout Middle-Far-Infrared Imaging (2011)

A quantum dot (QD) middle-far-infrared (MFIR) detection and imaging approach based on all-optical-readout (AORO) is proposed. Using the intersubband (ISB) optical transition to change the interband (IB) absorption, it converts the ISB MFIR signal into the IB near-infrared signal. It might overcome the problems in the electrical readout infrared detection and imaging, such as dark current, low-temperature operation, low resolution, and vulnerability to the high radiation intensity. Based on the In <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.5</sub> Ga <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0.5</sub> As/GaAs lens-shaped QD structure, our calculation shows the potential of this AORO approach for the MFIR detection and high-resolution imaging, the potential for room-temperature operation, and the ability for frequency selectivity and spectrum scanning.
