Bidirectional data flow analysis (1999)

Research in bidirectional data flow analysis seems to have come to a halt due to an impression that the case for bidirectional data flow analysis has been considerably weakened by a plethora of investigations based on decomposability of known bidirectional placement algorithms into a sequence of purely unidirectional components. This paper shows that the approach of decomposability is not general enough in that it derives its power from the simplifying graph transformation of edge-splitting and the favourable nature of flows in partial redundancy elimination (PRE). This follows from the fact that in the absence of edge-splitting, PRE cannot be performed using a sequence of cascaded unidirectional flows. Further, edge-splitting inherently converts data flows involved in PRE into unidirectional flows. In our opinion, this obviates the need of an alternative formulation. We also show that edge-splitting cannot convert data flows involved in "truly" bidirectional data flow problems into unidirectional flows. Thus not every bidirectional data flow problem can be converted into unidirectional flows. Besides, we argue that the premise that bidirectional analysis is more complex than unidirectional analysis, is invalid. We also mention some issues in bidirectional data flow analysis which need to be investigated.
In-plane conductive heat tansfer in solid and porous planar structures (2011)

Methods for determining the in-plane thermal diffusivity in a planar sample geometry were developed. These methods were tested and verified by measuring planar metal samples with known thermal properties. The techniques used were based on heating the sample at one edge and recording the evolution of the temperature field in the sample by a thermographic camera. The temperature fields at different times were processed and then fitted by a solution to a heat equation describing the experimental setup, thermal diffusivity as one of the fitting parameters. In the first experimental setup the sample was placed in a weak constant flow of air, and the situation was improved in the second setup by placing the sample in a vacuum chamber, where convective heat transfer was totally removed. After verification measurements, the latter setup was applied to porous sintered bronze samples, and their effective thermal conductivities were determined. The sintered samples were also imaged by X-ray microtomography so as to obtain a 3D model for their structure. It was shown that the effective thermal conductivity of the samples could be predicted by an analytical expression which involved certain parameters determined from the 3D images. Finally, as another application of the heat equation, propagation of temperature profiles in the form of slow-combustion fronts were studied in sheets of paper. The dynamical properties of these fronts belong to the KPZ universality class, for which theoretical results are available for the height-fluctuation distributions. Height fluctuations for such fronts were determined experimentally, and their distributions were found to be well fitted by corresponding theoretical distributions.
SE3-nets: Learning rigid body motion using deep neural networks (2017)

We introduce SE3-Nets which are deep neural networks designed to model and learn rigid body motion from raw point cloud data. Based only on sequences of depth images along with action vectors and point wise data associations, SE3-Nets learn to segment effected object parts and predict their motion resulting from the applied force. Rather than learning point wise flow vectors, SE3-Nets predict SE(3) transformations for different parts of the scene. Using simulated depth data of a table top scene and a robot manipulator, we show that the structure underlying SE3-Nets enables them to generate a far more consistent prediction of object motion than traditional flow based networks. Additional experiments with a depth camera observing a Baxter robot pushing objects on a table show that SE3-Nets also work well on real data.

Preclipping experiment for subcarrier-multiplexedAM/64QAM optical transmission (1995)

Bit-error-rate degradation of the 64QAM signal due to clipping distortion caused by overmodulation at the laser diode is compensated for by preclipping for subcarrier-multiplexed AM/64QAM optical transmission. The worst composite distortions of CSO < –60 dBc and CTB < –65 dBc have been achieved in the 40-channel AM signal band. It has also been confirmed that preclipping is more effective than Reed-Solomon (204, 188) error correction against clipping distortion.
A 14-Gb/s 32 mW AC coupled receiver in 90-nm CMOS (2007)

This paper introduces a high-speed AC coupled receiver architecture for high density interconnects. The proposed architecture combines a novel hysteresis circuit path and a linear broadband amplifier path to recover a NRZ signal from an 80-fF capacitively coupled channel. Using this dual path technique, a 90-nm CMOS prototype achieves 14-Gb/s operation while consuming 32 mW from a 1.2-V supply. The measured sensitivity of the receiver is better than 100 mVp-p differential.
Visualization of ribosome-recycling factor on the <i>Escherichia coli</i> 70S ribosome: Functional implications (2004)

After the termination step of protein synthesis, a deacylated tRNA and mRNA remain associated with the ribosome. The ribosome-recycling factor (RRF), together with elongation factor G (EF-G), disassembles this posttermination complex into mRNA, tRNA, and the ribosome. We have obtained a three-dimensional cryo-electron microscopic map of a complex of the Escherichia coli 70S ribosome and RRF. We find that RRF interacts mainly with the segments of the large ribosomal subunit's (50S) rRNA helices that are involved in the formation of two central intersubunit bridges, B2a and B3. The binding of RRF induces considerable conformational changes in some of the functional domains of the ribosome. As compared to its binding position derived previously by hydroxyl radical probing study, we find that RRF binds further inside the intersubunit space of the ribosome such that the tip of its domain I is shifted (by approximately 13 A) toward protein L5 within the central protuberance of the 50S subunit, and domain II is oriented more toward the small ribosomal subunit (30S). Overlapping binding sites of RRF, EF-G, and the P-site tRNA suggest that the binding of EF-G would trigger the removal of deacylated tRNA from the P site by moving RRF toward the ribosomal E site, and subsequent removal of mRNA may be induced by a shift in the position of 16S rRNA helix 44, which harbors part of the mRNA.

PHENOLIC ANTIOXIDANTS OF DRIED SOYBEANS (1978)

ABSTRACT Whole dried soybean seeds were investigated to determine the nature of their antioxidant activity. Activity was measured by rates of carotene bleaching in the coupled oxidation of linoleic acid and β‐carotene. Methanolic extracts of the soybeans were found to possess potent antioxidant ability. Paper and Sephadex column chromatography gave incomplete resolution of individual components. Therefore, thin‐layer chromatography of the whole methanolic extract rather than individual column fractions was used in isolating this component. Three fluorescent bands were found to possess the major activity. The most potent complex was further analyzed. Thin‐layer chromatography was used to separate the complex into four fluorescent components. One compound was determined to be responsible for the antioxidant activity exhibited by the parent band. Further analysis of this component by paper chromatography, chromogenic spray reagent tests, and ultraviolet spectral analyses indicated that the antioxidant was an isoflavone pentoside.
A Continent lleostomy Device (1983)

The feasibility of achieving fecal continence by mechanical occlusion of an end-ileostomy is explored. Accordingly, progressive stomal occlusion with an indwelling occluding device was evaluated in four healthy patients with Brooke ileostomies. Pre-occlusion clinical and physiologic tests were done, including fat balance, intestinal transit time, ileal motility and absorption, ileal compliance, ileal radiography, and ileoscopy. Progressive stomal occlusion was then employed until periods of occlusion of 5 to 8 hours were achieved after 10 to 16 weeks. Pre-occlusion tests were then repeated. Patients mastered use of the occluding device rapidly, and the device achieved reliable stomal continence in each patient. Whereas ileal capacity was small initially, intermittent occlusion resulted in a large, capacious ileal reservoir. Fasting ileal motility was increased slightly by stomal occlusion, although intestinal transit during feeding was not altered. Also, ileal absorption of glucose, electrolytes, vitamin B-12, and fat were not changed, and ileal mucosa at the site of occlusion remained intact endoscopically. The authors concluded that chronic intermittent occlusion of a Brooke ileostomy with an indwelling stomal device achieved enteric continence without impairing intestinal function.
High performance and scalable I/O virtualization via self-virtualized devices (2007)

While industry is making rapid advances in system virtualization, for server consolidation and for improving system maintenance and management, it has not yet become clear how virtualization can contribute to the performance of high end systems. In this context, this paper addresses a key issue in system virtualization - how to efficiently virtualize I/O subsystems and peripheral devices. We have developed a novel approach to I/O virtualization, termed self-virtualized devices, which improves I/O performance by off loading select virtualization functionality onto the device. This permits guest virtual machines to more efficiently (i.e., with less overhead and reduced latency) interact with the virtualized device. The concrete instance of such a device developed and evaluated in this paper is a self-virtualized network interface (SV-NIC), targeting the high end NICs used in thehigh performance domain. The SV-NIC (1) provides virtual interfaces (VIFs) to guest virtual machines for an underlying physical device, the network interface, (2) manages the wayin which the device's physical resources are used by guest operating systems, and (3) provides high performance, low overhead network access to guest domains. Experimental results are attained in a prototyping environment using an IXP 2400-based ethernet board as a programmable network device. The SV-NIC scales to large numbers of VIFs and guests, and offers VIFs with 77% higher throughput and 53% less latency compared to the current standard virtualized device implementations on hyper visor-based platforms.
Examination of the polished surface character of fused silica (1992)

Investigation of the surface character of fused silica polished with various compounds dispersed in water identified pH 4 as the optimum condition for high quality. Analyses support the conclusion that at this pH redeposition of hydrated material onto the surface during polishing is limited. Comparative polishing results for Zerodur are included. Improvement of the laser-damage threshold of a coating on the pH 4 polished fused silica is suggested.
Novel role of plasmacytoid dendritic cells in humans: Induction of interleukin‐10–producing treg cells by plasmacytoid dendritic cells in patients with rheumatoid arthritis responding to therapy (2009)

These results demonstrate, for the first time, that human plasmacytoid DCs may be educated within the rheumatoid microenvironment to acquire a tolerogenic phenotype. Modulation of the immune response by plasmacytoid DCs might provide novel immune-based therapies in autoimmunity and transplantation.
Deep belief networks for i-vector based speaker recognition (2014)

The use of Deep Belief Networks (DBNs) is proposed in this paper to model discriminatively target and impostor i-vectors in a speaker verification task. The authors propose to adapt the network parameters of each speaker from a background model, which will be referred to as Universal DBN (UDBN). It is also suggested to backpropagate class errors up to only one layer for few iterations before to train the network. Additionally, an impostor selection method is introduced which helps the DBN to outperform the cosine distance classifier. The evaluation is performed on the core test condition of the NIST SRE 2006 corpora, and it is shown that 10% and 8% relative improvements of EER and minDCF can be achieved, respectively.
The program complex of studying crypto algorithm Rijndael (2004)

The program complex of studying block crypto algorithm Rijndael is offered, the feature of which is round by round realization of algorithm with possibility of visualization of intermediate results. The interface of the program complex is represented in this paper. The C language is selected for the development of the application, as it works with data at a bit level very effectively, that is very important for writing algorithms of encoding. Proceed from the assignment of the program, it was given the special attention to the development of the interface. It was decided to realize the program complex on the language Microsoft Visual C++. The designed program complex researched the degree of correlation among bit images that were obtained on different rounds of encrypting. The calculated coefficients of correlation do not exceed 0,1.
Visual saliency for automatic target detection, boundary detection, and image quality assessment (2010)

We present a visual saliency detection method and its applications. The proposed method does not require prior knowledge (learning) or any pre-processing step. Local visual descriptors which measure the likeness of a pixel to its surroundings are computed from an input image. Self-resemblance measured between local features results in a scalar map where each pixel indicates the statistical likelihood of saliency. Promising experimental results are illustrated for three applications: automatic target detection, boundary detection, and image quality assessment.
Cell-specific expression of transforming growth factor-beta in rat liver. Evidence for autocrine regulation of hepatocyte proliferation. (1995)

Expression of the group of cytokines known as transforming growth factor-beta (TGF-beta 1, -beta 2 and -beta 3) is increased during liver regeneration induced by a 70% partial hepatectomy. The origin of these changes was examined in purified isolates of hepatocytes, sinusoidal endothelial cells, Kupffer cells (liver macrophages), and lipocytes (Ito or stellate cells) from normal and regenerating liver. In normal liver, TGF-beta 1 and -beta 2 levels were relatively high in sinusoidal endothelial cells and Kupffer cells. After partial hepatectomy, an early peak of TGF-beta 2 and -beta 3 was present in all four cell types, followed by a sustained increase in mRNA for TGF-beta 1, -beta 2, and -beta 3 primarily in the hepatocyte population. The specificity of these changes was established by examining a mechanistically different injury model, fibrosis induced by ligation of the biliary duct. In this model, TGF beta mRNA was increased only in lipocytes and the increase was progressive over a 7-d period of observation. Secretion of TGF beta protein was examined in cell isolates placed in short-term primary culture and generally reflected the corresponding mRNA level. The TGF beta released by hepatocytes was entirely in the latent form, whereas the individual nonparenchymal cell isolates released 50-90% active TGF beta. Hepatocyte-conditioned culture medium, after treatment to activate latent TGF beta, inhibited hepatocellular DNA synthesis as did the authentic factor. The data indicate that after injury TGF beta increases selectively in the cells that are the target of the factor, i.e., in hepatocytes after partial hepatectomy and in lipocytes in inflammation and fibrosis. We conclude that the effects of TGF beta in liver regeneration and fibrogenesis are predominantly, if not exclusively, autocrine.
Phenotype-genotype correlation in multiple primary lung cancer patients in China (2016)

Due to recent advances in high-resolution detection technology, multiple primary lung cancer (MPLC) is becoming an increasingly common diagnosis. However, the genotype-phenotype correlations in MPLC patients have not yet been assessed. In this study, we analyzed the clinical and pathological data for 129 consecutive MPLC patients who received curative surgery at the Tongji University Shanghai Pulmonary Hospital, China. We have screened 129 patients in the present study and found mutations in EGFR, BRAF, ROS1 and KRAS genes, as well as the rearrangement of the EML4-ALK gene in 113 patients. The mean patient age was 59.9 (25-78) years old and 41 patients were males (31.8%). Among the total patients, 123 (95.4%) had two primary lesions, 5 (3.9%) had three primary lesions, and 1 (0.8%) had four primary lesions. In 38.8% of the patients, all lesions were located on only one side of the body. Most of the detected mutations (98 patients) were in the EGFR gene. The patients exhibited significant differences in the EGFR mutation, age at diagnosis, and foci location.
AI Application to Data Analysis, Automatic File Processing (2018)

The state of the art of data engineering and statistical algorithms opens the possibility for automating certain tasks Although field types of columns may not be known in advance, we assume data type is enforced, e.g., that date fields have nothing but dates, in some specific format. Data related tasks include feature engineering, data processing, text recognition and errors detection. For example, of interest to auditors is detection of input errors in financial spreadsheets, fraudulent transactions, abusive insurance claims, etc. Clearly, for a large dataset, an auditor cannot possibly go through the entire set of records, so a way to highlight records of interest may be of great value by increasing audits productivity. Once an auditor has identified a suspect record, he/she may be interested to give “similar” record a closer examination. In this short essay we demonstrate the plausibility of automating the process of feature creation, outlier detection and calculating the distance between any two records in a spreadsheets whereby providing the proverbial auditor the means to quickly identify strange and unusual records.

Generalized Additive Models (2017)

This chapter discusses the innovations of additional flexible methods for modeling an individual term in an additive model. It focuses on how we fit additive models. A general and efficient algorithm for fitting a generalized additive model consists of a hierarchy of three modules: scatterplot smoothers, backfitting algorithm, and local-scoring algorithm. These three steps are a rather natural and intuitive generalization of the usual linear model algorithms, and that is how they were originally conceived. The algorithm for fitting a gam is exactly analogous to the algorithm for glms. The chapter presents the S functions for fitting and understanding generalized additive models. In some cases, especially for generalized linear or additive models, adding residuals to a plot is unhelpful because they can distort the scale dramatically. Any interesting features in the functions get lost because of a few large residuals, even though they may carry a very small weight.
Multiple-goal task realization utilizing redundant degrees of freedom of task and tool attachment optimization (2011)

Minimizing the task completion time of manipulator systems is essential in order to achieve high productivity. In this paper, this problem is dealt with by utilizing the redundant degrees of freedom (DOF) of a given task and the tool attachment optimization. For example, in a vision-based inspection where a camera is held by a manipulator, the extra DOF can be brought about by allowing the camera to be translated along its approach axis or rotated about this axis when capturing images. Furthermore, the manipulator end-effector position and orientation is optimized by designing an additional linkage at the manipulator end-effector which is called a tool attachment. A 7-DOF manipulator system is used in the simulations to verify the proposed approach. Results showed that this approach can minimize the task completion time by about 17% compared to conducting only motion coordination.
SNES: single nucleus exome sequencing (2015)

Abstract Single-cell genome sequencing methods are challenged by poor physical coverage and high error rates, making it difficult to distinguish real biological variants from technical artifacts. To address this problem, we developed a method called SNES that combines flow-sorting of single G1/0 or G2/M nuclei, time-limited multiple-displacement-amplification, exome capture, and next-generation sequencing to generate high coverage (96%) data from single human cells. We validated our method in a fibroblast cell line, and show low allelic dropout and false-positive error rates, resulting in high detection efficiencies for single nucleotide variants (92%) and indels (85%) in single cells.
