Comparison of ANN Controller and PID Controller for Industrial Water Bath Temperature Control System using MATLAB Environment (2012)

Artificial Neural Network is an effective tool for highly nonlinear system. With the advent of high-speed computer system, there is more increased interest in the study of nonlinear system. Neuro control algorithm is mostly implemented for the application to robotic systems and also some development has occurred in process control systems. Process Control systems are often nonlinear and difficult to control accurately. Their dynamic models are more difficult to derive than those used in aerospace or robotic control, and they tend to change in an unpredictable way. This paper gives an example where a multilayered feed forward back propagation neural network is trained offline to perform as a controller for a temperature control system with no a priori knowledge regarding its dynamics. The inverse dynamics model is developed by applying a variety of input vectors to the neural network. The performance of neural network based on these input vectors is observed by configuring it directly to control the process. In this paper, we have compared the performance of PID controller with ANN [1] based upon Set point change, Effect of load disturbances and Processes with variable dead time. The result shows that ANN outperforms the PID controller.
Reduced expression of TANGO in colon and hepatocellular carcinomas (2007)

The TANGO gene was originally identified as a new family member of the MIA gene family. The gene codes for a 14-kDa protein of so far unknown function. Recently, we identified TANGO as a tumor suppressor in malignant melanoma. In this study we evaluated TANGO transcription in different colon and hepatocellular carcinoma cell lines and tissue samples, to analyze whether loss of TANGO expression is a more general process in tumor development. TANGO was down-regulated or lost in all hepatocellular and colon cell lines compared to primary human hepatocytes or normal colon epithelial cells, respectively, and in most of the tumor samples compared to non-tumorous tissue. These results were confirmed in situ by immunohistochemistry on paraffin-embedded sections of colon and hepatocellular tumors. Functional assays with exogenous TANGO treatment of colon and hepatoma cell lines revealed reduced motility and invasion capacity. Our studies present for the first time the down-regulation of TANGO in colon and hepatocellular carcinoma and provide the first indications for a tumor suppressor role of the TANGO gene in human colon and hepatocellular carcinoma. Thus, functional relevant loss of TANGO expression may contribute to general tumor development and progression, and may provide a new target for therapeutic strategies.

Chemistry modification of high oxygen-carbon powder by plasma melting (1996)

State-of-the-art melting of tantalum and tantalum alloys has relied on electron beam (EB) or vacuum-arc remelting (VAR) for commercial ingot production. The limited number of melting techniques for these materials are the result of high melting temperatures and reactivity with conventional mold/crucible materials. In addition, the required vacuum levels used in the EB and VAR processes limit these techniques to relatively low interstitial content material due toe extensive outgassing during melting. Plasma arc melting (PAM) provides and alternative for melting tantalum and offers the advantage or processing under inert or other gases rather than vacuum, The plasma process is not sensitive to materials outgassing and allows for the direct recycling of material that would otherwise be reprocessed by chemical extraction. The current work examines melting of high interstitial content tantalum powder by the plasma arc process. Various cover gases of argon-hydrogen and helium-hydrogen were investigated to determine best melt quality. Melted ingots were characterized by chemical and metallographic methods to determine overall interstitial content, compound and morphology.
Expression of gap junction proteins connexin 26 and connexin 43 in normal human breast and in breast tumours (1998)

Gap junctional intercellular communication (GJIC) has been proposed as a cellular mechanism for tumour suppression and there is experimental evidence in support of this. If aberrant GJIC contributes to the formation of human breast tumours, one might expect that the connexins (gap junction proteins) expressed by epithelial cells in normal human breast would be down-regulated in tumour epithelial cells, or that tumour cells might show aberrant expression of other connexin family members. This study examines the immunocytochemical expression of connexins 26 (Cx26) and 43 (Cx43) in normal human breast, 11 benign breast lesions, two special-type carcinomas, and 27 invasive carcinomas of no special histological type (NST). Cx26 generally was not expressed at detectable level in normal human breast, but punctate Cx43 immunostaining of the myoepithelial cells was found. Cx43 staining of the myoepithelium was also a feature of the benign lesions and ductal carcinoma in situ (DCIS). In general, the epithelial cells of benign lesions failed to stain for either connexin. Similarly, a lobular carcinoma did not express Cx26 or Cx43, but there was punctate Cx43 in the epithelial cells of a mucoid carcinoma. Cx26 was up-regulated in the carcinoma cells of 15 of the 27 invasive NST carcinomas, although the staining was usually cytoplasmic and heterogeneous. Cx43 was expressed by stromal cells, possibly myofibroblasts, in all NST carcinomas. Furthermore, there was heterogeneous Cx43 expression in the carcinoma cells of 14 of the 27 NST carcinomas and the staining was often intercellular and punctate, characteristic of functional connexins. Up-regulated of Cx26 and/or Cx43 in the carcinoma cells of over two-thirds of invasive lesions of NST is not necessarily inconsistent with a tumour suppressor role for GJIC. However, the role of gap junctions in the formation and progression of solid human tumours is likely to be more complex than indicated from experimental systems.
Dynamics of linear protein polymer disassembly. (1980)

This report presents a kinetic model for endwise depolymerization of linear, self-assembling protein systems.We develop a reliable method for predicting the shape of depolymerization curves (remaining polymer weight versus time) on the basis of the initial polymer length distribution.Computer simulations are used to illustrate changes in the polymer length distribution and average polymer weight during disassembly.In addition, our method provides an accurate determination of the microscopic rate constant for subunit release.Application of this analysis to dilution-induced and cold induced disassembly of microtubules is illus-
SHaPE: A Novel Graph Theoretic Algorithm for Making Consensus-Based Decisions in Person Re-identification Systems (2017)

Person re-identification is a challenge in video-based surveillance where the goal is to identify the same person in different camera views. In recent years, many algorithms have been proposed that approach this problem by designing suitable feature representations for images of persons or by training appropriate distance metrics that learn to distinguish between images of different persons. Aggregating the results from multiple algorithms for person re-identification is a relatively less-explored area of research. In this paper, we formulate an algorithm that maps the ranking process in a person re-identification algorithm to a problem in graph theory. We then extend this formulation to allow for the use of results from multiple algorithms to make a consensus-based decision for the person re-identification problem. The algorithm is unsupervised and takes into account only the matching scores generated by multiple algorithms for creating a consensus of results. Further, we show how the graph theoretic problem can be solved by a two-step process. First, we obtain a rough estimate of the solution using a greedy algorithm. Then, we extend the construction of the proposed graph so that the problem can be efficiently solved by means of Ant Colony Optimization, a heuristic path-searching algorithm for complex graphs. While we present the algorithm in the context of person reidentification, it can potentially be applied to the general problem of ranking items based on a consensus of multiple sets of scores or metric values.

The principle of topology circuit is analyzed and simulation results confirm the validity of the analysis, morever, a 2kW experimental prototype is designed. A wide regulation capability of the output voltage, high power factor and high efficiency is obtained in this circuit. It will be a practical topology.
U7 small nuclear ribonucleoprotein represses histone gene transcription in cell cycle-arrested cells (2012)

Histone gene expression is tightly coordinated with DNA replication, as it is activated at the onset of S phase and suppressed at the end of S phase. Replication-dependent histone gene expression is precisely controlled at both transcriptional and posttranscriptional levels. U7 small nuclear ribonucleoprotein (U7 snRNP) is involved in the 3'-end processing of nonpolyadenylated histone mRNAs, which is required for S phase-specific gene expression. The present study reports a unique function of U7 snRNP in the repression of histone gene transcription under cell cycle-arrested conditions. Elimination of U7 snRNA with an antisense oligonucleotide in HeLa cells as well as in nontransformed human lung fibroblasts resulted in elevated levels of replication-dependent H1, H2A, H2B, H3, and H4 histone mRNAs but not of replication-independent H3F3B histone mRNA. An analogous effect was observed upon depletion of Lsm10, a component of the U7 snRNP-specific Sm ring, with siRNA. Pulse-chase experiments revealed that U7 snRNP acts to repress transcription without remarkably altering mRNA stability. Mass spectrometric analysis of the captured U7 snRNP from HeLa cell extracts identified heterogeneous nuclear (hn)RNP UL1 as a U7 snRNP interaction partner. Further knockdown and overexpression experiments revealed that hnRNP UL1 is responsible for U7 snRNP-dependent transcriptional repression of replication-dependent histone genes. Chromatin immunoprecipitation confirmed that hnRNP UL1 is recruited to the histone gene locus only when U7 snRNP is present. These findings support a unique mechanism of snRNP-mediated transcriptional control that restricts histone synthesis to S phase, thereby preventing the potentially toxic effects of histone synthesis at other times in the cell cycle.

Mechanism of Photoconductivity in Chemically Deposited Lead Sulfide Layers (1971)

Many of the classical problems involved in the mechanism of photoconductivity in chemically deposited PbS layers have been resolved by a combination of (a) materials control, (b) measurements of conductivity, photoconductivity, Hall effect, thermoelectric effect, and oxygen sorption, and (c) analysis of an inhomogeneous model. The dark conductivity process, characterized by a small thermally activated mobility, is the same for samples without added oxidant in the deposition and for samples with added oxidant, and is dominated by intergrain barriers to free-hole transport. Carrier densities derived from Hall measurements are equal to those derived from thermoelectric power measurement and are therefore interpreted to be equal to the carrier density in the grains of the PbS layer. Layers prepared without added oxidant are only very weakly photosensitive, corresponding to sensitizing centers lying 0.13 eV below the conduction band, whereas layers prepared with added oxidant are strongly photosensitive, corresponding to sensitizing centers lying 0.22 eV below the conduction band. In all cases photoconductivity results primarily from an increase in free hole density, with some small contribution from an increase in hole mobility. Increases in hole mobility caused either by photoexcitation or by photoadsorption of oxygen are attributed to an increase in hole tunneling through intergrain barriers as the results of decreased depletion layer widths. Oxygen adsorbed on the free surface of the layer increases the free-hole density without appreciably affecting the mobility; oxygen which is adsorbed on the surface and then diffuses to intergrain barriers increases the free-hole density, and also to a lesser extent the hole mobility and the hole lifetime. In several ways the results following from photoexcitation and photoadsorption of oxygen are similar, and they may both be described in terms of the same inhomogeneous model.
Evaluation of the Affinity and Turnover Number of Both Hepatic Mitochondrial and Microsomal Carnitine Acyltransferases:  Relevance to Intracellular Partitioning of Acyl-CoAs (1999)

Mitochondrial carnitine palmitoyltransferase I (CPT I) and microsomal carnitine acyltransferase I (CAT I) regulate the entry of fatty acyl moieties into their respective organelles. Thus, CPT I and CAT I occupy prominent positions in the pathways responsible for energy generation in mitochondria and the assembly of VLDL in the endoplasmic reticulum, respectively. Previous attempts to determine the intrinsic kinetic properties of CPT I and CAT I have been hampered by the occurrence of sigmoidal velocity curves. This was overcome, in this study, by the inclusion of recombinant acyl-CoA binding protein in the assay medium. For the first time, we have determined the concentrations of total functional enzyme (E(t)) by specific radiolabeling of the active site, the dissociation constants (K(d)) and the turnover numbers of CPT I and CAT I toward the CoA esters of oleic acid (C18:1) and docosahexaenoic acid (C22:6). The data show that carnitine inhibits CAT I at physiological concentrations which are not inhibitory to CPT I. Thus, carnitine concentration is likely to be a significant factor in determining the partitioning of acyl-CoAs between mitochondria and microsomes, a role which has not been previously recognized. Moreover, the finding that CAT I elicits a lower turnover toward the CoA ester of C22:6 (25 s(-)(1)) than toward that of C18:1 (111 s(-)(1)), while having similar K(d) values, suggests the use of this polyunsaturated fatty acid to inhibit VLDL biosynthesis.
What your firm should know about identity theft (2004)

Abstract Identity theft is the fastest‐growing crime in the United States. Many articles discuss steps individuals can take to minimize the risk of identity theft, but few realize the devastating effects this crime can have on businesses. Many firms may not even recognize the huge liability of not controlling information risks. The authors provide detailed advice on how to recognize, manage, and control those risks—so your firm doesn't become another victim. © 2004 Wiley Periodicals, Inc.
Patterns of Coronary Artery Movement and the Development of Coronary Atherosclerosis (2003)

Mechanical stress in coronary arteries has been postulated to cause endothelial injury and atherosclerotic lesions, but the relationship between the pattern of coronary artery movement (CAM) and lesion severity is not known. In the present study CAM was classified into 10 patterns, which were grouped into 3 classes: (1) bend type = coronary artery flexes into a curve; (2) compression type = segmental length is shortened without vertical deviation of the artery; (3) displacement type = location of the coronary artery shifts without change of segmental length or shape. Assessment of CAM was made for 6 segments from the left anterior descending artery and 3-5 segments from the left circumflex artery, and in total 673 segments were analyzed. Coronary arterial segments with the compression type had a significantly higher percent stenosis than those without it (Compression 57.9+/-29.4 % vs Bend 7.9+/-19.0 %, Displacement 4.3+/-13.0 %; p<0.00001). The compression type was seen frequently in the proximal and mid left anterior descending artery, ostial diagonal branch, obtuse marginal branch and mid left circumflex artery. The critical CAM (eg, compression pattern) may be an important mechanical stress inducing coronary atherosclerosis.
Privacy-preserving photo sharing based on a public key infrastructure (2015)

A significant number of pictures are posted to social media sites or exchanged through instant messaging and cloud-based sharing services. Most social media services offer a range of access control mechanisms to protect users privacy. As it is not in the best interest of many such services if their users restrict access to their shared pictures, most services keep users' photos unprotected which makes them available to all insiders. This paper presents an architecture for a privacy-preserving photo sharing based on an image scrambling scheme and a public key infrastructure. A secure JPEG scrambling is applied to protect regional visual information in photos. Protected images are still compatible with JPEG coding and therefore can be viewed by any one on any device. However, only those who are granted secret keys will be able to descramble the photos and view their original versions. The proposed architecture applies an attribute-based encryption along with conventional public key cryptography, to achieve secure transmission of secret keys and a fine-grained control over who may view shared photos. In addition, we demonstrate the practical feasibility of the proposed photo sharing architecture with a prototype mobile application, ProShare, which is built based on iOS platform.
V79 Chinese hamster cells genetically engineered for polymorphic cytochrome P450 2D6 and their predictive value for humans. (2003)

With more than 30 genetic variants human cytochrome P450 2D6 (CYP2D6) presents the most extensive variation among all cytochromes P450. At the same time, roughly 30% of all drugs are metabolised by CYP2D6. Therefore, V79 Chinese hamster cells were genetically engineered for the genetic variants *1, *2, *9, *10, and *17 encoding active enzymes. These cells are to be used to understand and to predict variant-dependent metabolism of drugs and drug candidates. The V79-derived cell lines were extensively characterised for stable expression of mRNA, for enzyme activity using bufuralol hydroxylation, for CYP content by CO difference spectra, and for protein distribution and cellular location by in situ immunofluorescence. Based on these results, CYP-mediated metabolism of tamoxifen was investigated.
Novel quantum dot enhancement film with a super-wide color gamut for LCD displays (2018)

We present a novel quantum dot enhancement film (QDEF) with a remarkable RGB color gamut of over 100.4% (134.2%) of the Rec. 2020 standard (NTSC standard), respectively for a high-resolution liquid-crystal display (LCD). Our efficient QDEF was fabricated by using a highly transparent resin incorporated with high photoluminesce-quantum yield (PL-QY) and narrow full width at half maximum CsPbBr1I2 QDs (Pr-QDs) and CdSe/ZnS QDs (Cd-QDs). The proposed PrCd-QDEF in a LCD with color filters rendered a blue photoluminesce (PL) peak at 452 nm with a FWHM of 20.4 nm, a green PL peak at 530.1 nm with a FWHM of 23.8 nm, and a red color peak at 652.4 nm with a FWHM of 28.1 nm. Moreover, The PrCd-QDEF did not show any cross-talk between the RGB PL colors. Such promising optical results, along with the simple and cost-effective preparation technique, might encourage the manufacture of super high resolution LCDs using a PrCd-QDEF.

Compound 48/80, a histamine-depleting agent, blocks the protective effect of morphine against electroconvulsive shock in mice (2000)

We have shown that morphine has an anticonvulsive effect against maximal electroconvulsive shock (MES) in mice, and this effect is antagonized by histamine H1-receptor antagonists. Brain histamine is localized both in neurons and in mast cells, and morphine is known to enhance the turnover of neuronal histamine and to release histamine from mast cells. In the present experiments, compound 48/80 was injected chronically (0.5 mg/kg on day 1, 1 mg/kg on day 2, 2 mg/kg on day 3, 3 mg/kg on day 4, and 4 mg/kg on day 5, twice daily, ip) to deplete mast cell contents. Morphine (0.001-10 mg/kg, ip; N = 20) produced a dose-dependent anticonvulsive effect against MES seizure in mice with non-depleted mast cells, whereas it did not exert any anticonvulsive effect in mice with depleted mast cells. These results indicate that morphine produces its anticonvulsive effect against maximal electroconvulsive shock in mice by liberating histamine from mast cells.
