Parametric Matching Pursuit Methods to Reconstruct Seismic Data Acquired with Multichannel Sampling (2011)

In marine seismic data acquisition, multichannel sampling can occur in various scenarios, including over/under streamers, multicomponent streamer, and multicomponent ocean-bottom node. In these various multichannel sampling scenarios, each channel outputs samples of a filtered version of a seismic wavefield. These filters are different for each channel; the data are often coarsely and irregularly sampled. The objective is to reconstruct the unknown wavefield from the multichannel samples. In this paper, we discuss how parametric matching pursuit methods can be extended to solve such reconstruction problems. We give two examples based on data that a multicomponent streamer could record and show the form the reconstruction problem takes when two- and three-component data are available.
Texture mapping-based virtual simulation of striped jacquard fabrics (2023)

Fabric computer-aided design has become a hot research topic in recent years. The main objective of this research is to innovate a method of design, simulation and virtual display for weft-knitted striped jacquard fabrics. Preferentially, the fabric design and simulation models were established and the virtual yarns are intermeshed by connecting each control point of the loops to generate the structural simulation. The simulated image was captured as the texture image. The virtual display method of the garment based on texture mapping was mainly studied and innovated. Texture matching was realized based on the two-dimensional garment piece models and the vertices texture coordinates of the three-dimensional garment models were reset, then the three-dimensional garment virtual display was realized according to the mapping relationship between the triangles. During this process, the position of the texture can be dynamically designed and adjusted to achieve the desired effect. This research introduced the design of four kinds of striped fabrics and illustrated the corresponding simulation and virtual display effect to verify the feasibility of the method. The analysis of simulation efficiency reveals that the method responds quickly and has favorable adaptability to diverse patterns and models. The research provides a new idea for the computer-aided design of knitted fabrics and promotes the development of personalized garment customization.
Long-time Interfacial Relaxation in Aqueous Butanol Solutions (2000)

The long-time relaxation of the dynamic surface tension (DST) in aqueous solutions of four structural isomers of butyl alcohol has been observed with the aid of the maximum bubble pressure technique. Diffusion-controlled kinetics was found to allow an apparently successful (in terms of the quality of fitting) description of the observed DST dynamics, but it leads to an unrealistically low value of the diffusion coefficient, 10-11−10-13 m2 s-1. Conversely, the activation-controlled kinetics fails to explain the slow damping of DST curves observed over long time periods. A comprehensive theoretical analysis supported by numerical simulations has conclusively shown that neither diffusion nor mixed diffusion-activation kinetics can adequately account for the observed slower DST relaxation. As an alternative explanation, the presence of packing defects in the adsorbed layer is proposed.
PRELIMINARY ASSESSMENT OF RX 72601, A NEW ANTICHOLINESTERASE IN MAN: REVERSAL OF COMPETITIVE NEUROMUSCULAR BLOCKADE (1974)

1 The effect of RX 72601, neostigmine plus atropine, or saline on neuromuscular blockade with (+)-tubocurarine was studied in a double blind trial in four healthy male volunteers. 2 The methods used to assess neuromuscular function were voluntary grip strength and indirectly evoked muscle twitches. The muscarinic action was assessed by measuring intestinal motility with a pressure sensitive radio pill, and auscultation of the abdomen. Blood pressure and pulse rate were also recorded. The degree of acetylcholinesterase inhibition achieved in whole blood was determined before and at intervals after the administration of the anticholinesterases. 3 Both RX 72601 (0.66-0.83 mg) and neostigmine (2.5 mg) completely reversed the neuromuscular blockade produced by tubocurarine, but the time course of reversal differed. RX 72601 (0.66-0.83 mg) produced similar inhibition of acetylcholinesterase in whole blood to neostigmine (2.5 mg). The doses of RX 72601 used caused minimal stimulation at muscarinic sites as evidenced by the limited effect on pulse rate and intestinal activity. 4 It was concluded that RX 72601 could be safely used to reverse the effects of neuromuscular blockade without the need for premedication with atropine.
Production of Turanose by Cyclomaltodextrin Glucanotransferase from Bacillus stearothermophilus (2004)

Cyclomaltodextrin glucanotransferase (EC 2.4.1.19, abbreviated as CGTase) from Bacillus stearothermophilus produced a series of transfer products from a mixture of cyclomaltohexaose and D-fructose. After digestion with glucoamylase, the resultant product contained turanose and trehalulose in addition to D-glucose and D-fructose. These results showed that CGTase transferred the glucose residue to the C3- and C1-hydroxy groups of fructopyranose. The optimum conditions on the turanose production from α-CD and D-fructose using CGTase were examined. The reaction mixture containing 30% of α-CD and 30% of D-fructose and 300 U/g of α-CD of CGTase from B. stearothermophilus was incubated at 60°C and pH 5.5 for 24 h and then treated with glucoamylase. Turanose was produced in a yield of about 45%.
Informative features in vision and learning (2002)

We explore the role of features in solving problems in computer vision and learning. Features captures important domain-dependent knowledge and are fundamental in simplifying problems. Our goal is to consider the universal features of the problem concerned, and not just particular algorithms used in its solution. Such an approach reveals only the fundamental difficulties of any problem. For most problems we will face a host of other specialized concerns. Therefore, we consider simplified problems which captures the essence of our approach. 
This thesis consists of two parts. First, we explore means of discovering features. We come up with an information theoretic criterion to identify features which has deep connections to statistical estimation theory. We consider features to be “nice” representations of objects. We find that, ideally, a feature space representation of on image is the most concise representation of an image which captures all available information in it. In practice, however, we are satisfied with an approximation to it. Therefore, we explore a few such approximations and explain their connection to the information-theoretic approach. We look at the algorithms which implement these approximation and look at their generalizations in the related field of stereo vision. 
Using features, whether they come from some feature-discovery algorithm or are hand crafted, is usually an ad hoc process which depends on the actual problem, and the exact representation of features. This diversity mostly arises from the multitude of ways features capture information. In the second part of this thesis, we come up with an architecture which lets us use features in a very flexible way, in the context of content-addressable memories. We apply this approach to two radically different domains, face images and English words. We also look at human performance in reconstructing words from fragments, which give us some information about the memory subsystem in human beings.
Testosterone Facilitates the Baroreceptor Control of Reflex Bradycardia: Role of Cardiac Sympathetic and Parasympathetic Components (2001)

Reported clinical and experimental findings have shown that baroreflex control of heart rate is attenuated in women compared with men. This study investigated whether the sexual dimorphism in baroreflex function relates to the ability of the male hormone testosterone to facilitate baroreflex responsiveness. Relative contributions of the vagal and sympathetic autonomic components to testosterone modulation of baroreflex function were also investigated. Baroreflex curves relating changes in heart rate to increases or decreases in blood pressure evoked by phenylephrine and sodium nitroprusside, respectively, were constructed in sham-operated rats and castrated rats with and without testosterone replacement. Slope of the curves was taken as an index of baroreflex sensitivity (BRS PE and BRS NP ). Castration (for 10 days) significantly reduced plasma testosterone levels and attenuated reflex bradycardia, as indicated by significantly smaller BRS PE in castrated rats compared with values in sham-operated rats (-0.85 +/- 0.07 vs. -1.51 +/- 0.10 beats/min per mm Hg). Testosterone replacement in castrated rats restored plasma testosterone and BRS PE to levels similar to those of sham-operated rats. Muscarinic blockade by atropine caused 55% reduction in BRS PE in sham-operated rats, an effect that was significantly (p < 0.05) attenuated in castrated rats and restored to intact levels after testosterone supplementation. beta-Adrenergic blockade by propranolol caused slight and insignificant decreases in BRS PE. Castration and testosterone supplementation had no effect on BRS NP, ruling out a modulatory effect of testosterone on reflex tachycardia. These data provide the first experimental evidence of a favorable role for testosterone in baroreceptor control of reflex bradycardia. Further, baroreflex modulation by testosterone appears to be autonomically mediated and involves an enhancement of cardiomotor vagal activity.
Modeling of risk losses using size-biased data (2007)

In this paper we present a method for drawing inferences about the process of financial losses that are associated with the operations of a business. For example, for a bank such losses may be related to erroneous transactions, human error, fraud, lawsuits, or power outages. Information about the frequency and magnitude of losses is obtained through the search of a number of sources, such as printed, computerized, or Internet-based publications related to insurance and finance. The data consists of losses that were discovered in the search. We assume that the probability of a loss appearing in the body of sources and also being discovered increases with the magnitude of the loss. Our approach simultaneously models the process of losses and the process of populating the database. The approach is illustrated using data related to operational risk losses that are of special interest to the banking industry.

Analysis and Measurement of the Dynamic Motions of a Large-Scale Rotating Roll Workpiece (2012)

This paper describes the analysis and measurement of the dynamic motions of a large-scale rotating roll workpiece, which is used for a large-scale lathe, under the gravity condition. A dynamic model which includes the gravity effect was first established. In order to investigate the behavior which comes from stiffness differences of the journal bearing at the headstock and the tailstock, a spring-mass-damper system was also established. In addition to the simulations, the behavior of the rotating roll workpiece was investigated with respect to the different rotating speed. In the experiment, a mirror finished hollow type roll workpiece with a diameter of 320 mm, a length of 1800 mm, a weight of about 340 kg was fabricated by a large-scale lathe. Five capacitive type displacement sensors were mounted on the sensor holders which were arranged along the axis of rotation of the spindle. The behavior measurement was carried out at 5 sections of the roll workpiece along the axial direction. The rotating speed was set to be 5, 50, 100, 150, 200, 250 and 300 rpm. The dynamic model for the analysis with simulations and the measurement result of the behavior of a rotating roll workpiece according to the different rotating speed are presented in this paper.
Enabling CD SEM metrology for 5nm technology node and beyond (2017)

The CD SEM (Critical Dimension Scanning Electron Microscope) is one of the main tools used to estimate Critical Dimension (CD) in semiconductor manufacturing nowadays, but, as all metrology tools, it will face considerable challenges to keep up with the requirements of the future technology nodes. The root causes of these challenges are not uniquely related to the shrinking CD values, as one might expect, but to the increase in complexity of the devices in terms of morphology and chemical composition as well. In fact, complicated threedimensional device architectures, high aspect ratio features, and wide variety of materials are some of the unavoidable characteristics of the future metrology nodes. This means that, beside an improvement in resolution, it is critical to develop a CD SEM metrology capable of satisfying the specific needs of the devices of the nodes to come, needs that sometimes will have to be addressed through dramatic changes in approach with respect to traditional CD SEM metrology. In this paper, we report on the development of advanced CD SEM metrology at imec on a variety of device platform and processes, for both logic and memories. We discuss newly developed approaches for standard, IIIV, and germanium FinFETs (Fin Field Effect Transistors), for lateral and vertical nanowires (NW), 3D NAND (three-dimensional NAND), STT-MRAM (Spin Transfer Magnetic Torque Random-Access Memory), and ReRAM (Resistive Random Access Memory). Applications for both front-end of line (FEOL) and back-end of line (BEOL) are developed. In terms of process, S/D Epi (Source Drain Epitaxy), SAQP (Self-Aligned Quadruple Patterning), DSA (Dynamic Self-Assembly), and EUVL (Extreme Ultraviolet Lithography) have been used. The work reported here has been performed on Hitachi CG5000, CG6300, and CV5000. In terms of logic, we discuss here the S/D epi defect classification, the metrology optimization for STI (Shallow Trench Isolation) Ge FinFETs, the defectivity of III-V STI FinFETs,, metrology for vertical and horizontal NWs. With respect to memory, we discuss a STT-RAM statistical CD analysis and its comparison to electrical performance, ReRAM metrology for VMCO (Vacancy-modulated conductive oxide) with comparison with electrical performance, 3D NAND ONO (Oxide Nitride Oxide) thickness measurements. In addition, we report on 3D morphological reconstruction using CD SEM in conjunction with FIB (Focused Ion Beam), on optimized BKM (Best Known Methods) development methodologies, and on CD SEM overlay. The large variety of results reported here gives a clear overview of the creative effort put in place to ensure that the critical potential of CD SEM metrology tools is fully enabled for the 5nm node and beyond.
Size-dependent immune-modulating effect of amorphous nanosilica particles. (2011)

The immune-modulating effect following intradermal injection of various-sized amorphous silica particles was analyzed in terms of induction of ovalbumin-specific CD8+ T cells in vivo. IFN-gamma ELISPOT assays revealed that only nanosilica particles with a diameter of less than 100 nm significantly enhanced CD8+ T cell responses against ovalbumin. These results indicate that the size of nanomaterials is a critical determinant in terms of their safe use.
In vitro and in vivo prevention of HIV protease inhibitor‐induced insulin resistance by a novel small molecule insulin receptor activator (2004)

Protease inhibitor (PI) therapy for the treatment of patients infected with human immunodeficiency virus is frequently associated with insulin resistance and diabetic complications. These adverse effects of PI treatment result to a large extent from their inhibition of insulin-stimulated glucose transport. Insulin receptor (IR) activators that enhance the insulin signaling pathway could be effective in treating this resistance. However, there are no agents reported that reverse inhibition of insulin action by PIs. Herein, we describe the effects of TLK19781. This compound is a non-peptide, small molecule, activator of the IR. We now report in cultured cells, made insulin resistant HIV by PI treatment, that TLK19781 both increased the content of insulin-stimulated GLUT4 at the plasma membrane, and enhanced insulin-stimulated glucose transport. In addition, oral administration of TLK19781 with the PI, indinavir improved glucose tolerance in rats made insulin resistant. These results suggest, therefore, that IR activators such as TLK19781 may be useful in treating the insulin resistance associated with PIs.

Partial evaluation of logic programs (1988)

Partial evaluation refers to program transformation techniques based on local and incremental application of actual evaluation. We have developed a framework for partial evaluation of logic programs. By applying developed techniques to all predicate calls appearing in programs, better runtime performance can be achieved. Our framework selects proper partial evaluation techniques based on argument instantiations of calls. Major improvement over a currently know framework is that there would be no longer explosive growth of partially evaluated programs. In addition, our framework extends the range of applicability of partial evaluation to the level of comparisons of function symbols during unifications.
SARS-CoV-2 infected cells present HLA-I peptides from canonical and out-of-frame ORFs (2020)

T cell-mediated immunity may play a critical role in controlling and establishing protective immunity against SARS-CoV-2 infection; yet the repertoire of viral epitopes responsible for T cell response activation remains mostly unknown. Identification of viral peptides presented on class I human leukocyte antigen (HLA-I) can reveal epitopes for recognition by cytotoxic T cells and potential incorporation into vaccines. Here, we report the first HLA-I immunopeptidome of SARS-CoV-2 in two human cell lines at different times post-infection using mass spectrometry. We found HLA-I peptides derived not only from canonical ORFs, but also from internal out-of-frame ORFs in Spike and Nucleoprotein not captured by current vaccines. Proteomics analyses of infected cells revealed that SARS-CoV-2 may interfere with antigen processing and immune signaling pathways. Based on the endogenously processed and presented viral peptides that we identified, we estimate that a pool of 24 peptides would provide one or more peptides for presentation by at least one HLA allele in 99% of the human population. These biological insights and the list of naturally presented SARS-CoV-2 peptides will facilitate data-driven selection of peptides for immune monitoring and vaccine development.
Retroviral vector integration deregulates gene expression but has no consequence on the biology and function of transplanted T cells (2006)

The use of retroviral vectors in gene therapy has raised safety concerns for the genotoxic risk associated with their uncontrolled insertion into the human genome. We have analyzed the consequences of retroviral transduction in T cells from leukemic patients treated with allogeneic stem cell transplantation and donor lymphocytes genetically modified with a suicide gene (HSV-TK). Retroviral vectors integrate preferentially within or near transcribed regions of the genome, with a preference for sequences around promoters and for genes active in T cells at the time of transduction. Quantitative transcript analysis shows that one fifth of these integrations affect the expression of nearby genes. However, transduced T cell populations maintain remarkably stable gene expression profiles, phenotype, biological functions, and immune repertoire in vivo, with no evidence of clonal selection up to 9 yr after administration. Analysis of integrated proviruses in transduced cells before and after transplantation indicates that integrations interfering with normal T cell function are more likely to lead to clonal ablation than expansion in vivo. Despite the potentially dangerous interactions with the T cell genome, retroviral integration has therefore little consequence on the safety and efficacy of T cell transplantation.
Wireless Multi-group Multicast Precoding with Selective RF Energy Harvesting (2019)

We present a novel framework for multi-group multicast precoding in the presence of three types of wireless users which are distributed among various multicast groups. A multi-antenna transmitter conveys information and/or energy to the groups of corresponding receivers using more than one multicast streams. The information specific users have conventional receiver architectures to process data, energy harvesting users collect energy using the non-linear energy harvesting module and each of the joint information decoding and energy harvesting capable user is assumed to employ the separated architecture with disparate non-linear energy harvesting and conventional information decoding units. In this context, we formulate and analyze the problem of total transmit power minimization for optimal precoder design subjected to minimum signal-to-interference-and-noise ratio and harvested energy demands at the respective users under three different scenarios. This problem is solved via semi-definite relaxation and the advantages of employing separate information and energy precoders are shown over joint and per-user information and energy precoder designs. Simulation results illustrate the benefits of proposed framework under several operating conditions and parameter values.
Ion implantation in silicon to facilitate testing of photonic circuits (2017)

In recent years, we have presented results on the development of erasable gratings in silicon to facilitate wafer scale testing of photonics circuits via ion implantation of germanium. Similar technology can be employed to develop a range of optical devices that are reported in this paper. Ion implantation into silicon causes radiation damage resulting in a refractive index increase, and can therefore form the basis of multiple optical devices. We demonstrate the principle of a series of devices for wafers scale testing and have also implemented the ion implantation based refractive index change in integrated photonics devices for device trimming.
