Association of Hsp47, Grp78, and Grp94 with procollagen supports the successive or coupled action of molecular chaperones (1994)

Hsp47, Grp78, and Grp94 have been implicated with procollagen maturation events. In particular, Hsp47 has been shown to nascent procollagen alpha 1(I) chains in the course of synthesis and/or translocation into the endoplasmic reticulum (ER). Although, Hsp47 binding to gelatin and collagen has previously been suggested to be independent of ATP. Grp78 and Grp94 are known to dissociate from its substrates by an ATP-dependent release mechanism. The early association of Hsp47 with procollagen and its relatively late release suggested that other chaperones, Grp78 and Grp94, interact successively or concurrently with Hsp47. Herein, we examined how these events occur in cells metabolically stressed by depletion of ATP. In cells depleted of ATP, the release of Hsp47, Grp78, and Grp94 from maturing procollagen is delayed. Thus, in cells experiencing metabolic stress, newly synthesized procollagen unable to properly fold became stably bound to a complex of molecular chaperones. In that Hsp47, Grp78, and Grp94 could be recovered with nascent procollagen and as oligomers in ATP depleted cells suggests that these chaperones function in a series of coupled or successive reactions.
IMPLEMENTING A COMPUTER VISION SYSTEM FOR CORN KERNEL DAMAGE EVALUATION (2001)

A computer vision system was developed for evaluation of the total damage factor used in corn grading. Majorcategories of corn damage in the Midwestern U.S. grain market were blueeye mold damage and germ damage. Sevenhundred twenty kernels were obtained from officially sampled Federal Grain Inspection Service (FGIS) corn samples andclassified by inspectors on the Board of Appeals and Review. Inspectors classified these kernels into blueeye mold,germdamaged, and sound kernels at an 88% agreement rate. A color vision system and lighting chamber were developedto capture replicate images from each sample kernel. Images were segmented via input of red, green, and blue (RGB) valuesinto a neural network trained to recognize color patterns of blueeye mold, germ damage, sound germ, shadow in sound germ,hard starch, and soft starch. Morphological features (area and number of occurrences) from each of these color group areaswere input to a geneticbased probabilistic neural network for computer vision image classification of kernels into blueeyemold, germ damage, and sound categories. Correct classification by the network on unseen images was 78, 94, and 93%,respectively. Correct classification for sound and damaged categories on unseen images was 92 and 93%, respectively.
Degradation of benzene, toluene, ethylbenzene, and xylenes (BTEX) by the lignin-degrading basidiomycete Phanerochaete chrysosporium (1993)

Degradation of the BTEX (benzene, toluene, ethylbenzene, and o-, m-, and p-xylenes) group of organopollutants by the white-rot fungus Phanerochaete chrysosporium was studied. Our results show that the organism efficiently degrades all the BTEX components when these compounds are added either individually or as a composite mixture. Degradation was favored under nonligninolytic culture conditions in malt extract medium, in which extracellular lignin peroxidases (LIPs) and manganese-dependent peroxidases (MNPs) are not produced. The noninvolvement of LIPs and MNPs in BTEX degradation was also evident from in vitro studies using concentrated extracellular fluid containing LIPs and MNPs and from a comparison of the extents of BTEX degradation by the wild type and the per mutant, which lacks LIPs and MNPs. A substantially greater extent of degradation of all the BTEX compounds was observed in static than in shaken liquid cultures. Furthermore, the level of degradation was relatively higher at 25 than at 37 degrees C, but pH variations between 4.5 and 7.0 had little effect on the extent of degradation. Studies with uniformly ring-labeled [14C]benzene and [14C]toluene showed substantial mineralization of these compounds to 14CO2.
Quantum Field Theory in de Sitter Space: Renormalization by Point Splitting (1988)

We examine the modes of a scalar field in de Sitter space and construct quantum two-point functions. These are then used to compute a finite stress tensor by the technique of covariant point-splitting. We propose a renormalization ansatz based on the DeWitt-Schwinger expansion, and show that this removes all am biguities previously present in pointsplitting regularization. The results agree in detail with previous work by dimensional regularization, and give rise to an anomalous trace with the conventional coefficient. We describe how’ our treatment may be extended to more general situations.
Enzymatic browning reactions in apple and apple products (1994)

This review examines the parameters of enzymatic browning in apple and apple products that is, phenolic compounds, polyphenoloxidases, and other factors (ascorbic acid and peroxidases), both qualitatively and quantitatively. Then the relationships between intensity of browning and the browning parameters are discussed, including a paragraph on the methods used for browning evaluation. Finally, the different methods for the control of browning are presented.
[Use of various clinico-psychological methods in the differential diagnosis of depressive conditions]. (1990)

As many as 120 patients with endogenous depression, 116 patients with neurological depression and 100 healthy test subjects were examined using a number of psychological methods: Spilberger-Khanin test for reactive and personality anxiety, personality differential and a questionnaire of depressive conditions (QDC). The purpose of the investigation lay in the search for differential diagnostic criteria for depressive conditions. The task of the investigation also included clinical and neurobiological validation of the QDC. With this purpose in view, the results of the patients' testing with the aid of the QDC were compared with their clinical evaluation and dexamethazone test (DT) findings. The investigation has demonstrated the psychological methods employed to be suitable for the task of differential diagnosis of endogenous and neurotic depressions. The use of the clinical method and the DT has confirmed high validity of the QDC.
Magnetic Field Dependent Xenon-131 Quadrupolar Splitting in Gas and Liquid Phase NMR (1998)

At very high magnetic fields $({B}_{0}\ensuremath{\ge}14\mathrm{T})$, the NMR spectrum of xenon-131 in the gas phase $(\ensuremath{\sim}300\mathrm{K},400\mathrm{kPa})$ shows a well resolved quadrupolar splitting. The experimental results suggest a dual nature of the observed splitting. One portion arises from exchange with xenon atoms adsorbed on the surface of the surrounding container wall. Another portion, previously unreported, is strongly field dependent and does not appear to originate from such surface interactions. This term indicates an electrical polarization of the xenon electron shell induced by the applied static magnetic field.

Serious Games: Serious Opportunities (2004)

Computer and video games are primarily understood as a form of entertainment. Increasingly, however, they are becoming recognized as providing a powerful means for learning, both among educators and the game development community. For example, this year heralded the advent of the inaugural Serious Games Summit held during the Game Developers Conference in San Jose. The core focus of the summit was to bring together educators and game developers and investigate the current and future landscape of games and learning. This paper explores the notion of games as a means for learning, together with current research and applications of games within education and industry.
Modeling the interaction of IEEE 802.3x hop-by-hop flow control and TCP end-to-end flow control (2005)

Ethernet is rapidly expanding beyond its niche of local area networks. However, its success in larger metropolitan area networks will be determined by its ability to combine simplicity, low costs and quality of service. A key element in successfully transporting bursty traffic and at the same time providing QoS, is congestion control. The Ethernet standard IEEE 802.3x defines a hop-by-hop congestion control mechanism. The performance of this scheme generally depends on its interaction with higher layer application traffic, and especially, with TCP controlled traffic which has its own end-to-end congestion control mechanism. In this paper we focus on the performance modeling and analysis of this interaction. Our model takes into account the influence of various network and traffic parameters. The validity of the proposed model is assessed by comparison of the results to simulations. In our experiments we observe that an increase of the round trip time has a positive influence on the interaction of hop-by-hop and TCP congestion control, and that the use of hop-by-hop flow control is only beneficial when the load is not high.

Ultrafast chemical reactions between nickel and aluminum powders during shock loading (1992)

A recent investigation of powdered Ni-Al systems subject to shock loading has yielded evidence that reactions occur during the shock front. Time-resolved measurements of normal shock pressure indicate that an ‘‘excess pressure’’ is generated possibly due to an exothermic reaction in the Ni-Al system. These reactions appear to occur during the 100 ns that represent the shock front. A clear reaction threshold is observed and corroborated by micrographs of the recovered samples.
Dynamic Bandwidth Request-Allocation Algorithm for Real-Time Services in IEEE 802.16 Broadband Wireless Access Networks (2008)

The emerging broadband wireless access (BWA) technology based on IEEE 802.16 is one of the most promising solutions to provide ubiquitous wireless access to the broadband service at low cost. This paper proposes an efficient uplink bandwidth request-allocation algorithm for variable-rate realtime services in IEEE 802.16 BWA networks. In order to minimize bandwidth wastage without degrading quality of service (QoS), we introduce a notion of target delay and propose dual feedback architecture. The proposed algorithm calculates the amount of bandwidth request such that the delay is regulated around the desired level to minimize delay violation and delay jitter for real-time services. Also, it can maximize utilization of wireless channel by making use of dual feedback, where the bandwidth request is adjusted based on the information about the backlogged amount of traffic in the queue and the rate mismatch between packet arrival and service rates. Due to the dual feedback architecture, the proposed scheme responds quickly to the variation of traffic load and is robust to the change of network condition. We analyze the stability of the proposed algorithm from a control-theoretic viewpoint and derive a simple design guideline based on the analysis. By implementing the algorithm in OPNET simulator, we evaluate its performance in terms of queue regulation, optimal bandwidth allocation, delay controllability, and robustness to traffic characteristics.
On the efficiency of the transition fault model for delay faults (2002)

A study is presented concerning the efficiency of test pattern sets generated with the transition fault model applied to fine grained delay fault models. The authors have developed the delay fault simulator DELFI-a program which is capable of simulating timing failures of combinational circuits using different delay fault models. For the computer experiments the authors selected transition fault test pattern sets because they are very cost-effective to generate. The simulations of benchmark circuits demonstrate that the transition fault test patterns detect gross delay faults even at nodes with redundant stuck-at faults. Furthermore the results show that the transition fault test patterns are not sufficient for small delay faults in the range of a few gate delays. In order to receive a satisfactory coverage for these delay faults, the transition fault test sets must be extended.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Differential expression of proteases in human gestational tissues before, during and after spontaneous-onset labour at term (1999)

A number of tightly regulated proteolytic enzyme systems, including the plasminogen activation cascade and matrix metalloproteases, play integral roles in the remodelling of extracellular matrices during pregnancy and parturition. This study assessed these labour-associated changes in protease activity in human gestational tissues. Amnion, choriodecidua and placenta collected from women before (at caesarean section, not in labour), during (at caesarean section, in labour) and after (spontaneous-onset labour, normal vaginal delivery) labour were examined on gelatin-substrate SDS-PAGE zymography. All tissues displayed major 55 kDa plasminogen-dependent activity that was abolished by the serine protease inhibitors (10 mmol phenylmethyl-sulphonylfluoride l-1, 100 mmol epsilon aminocaproic acid l-1, 1 mmol Glu-Gly-Arg chloromethylketone l-1). The enzymic activity was identified as urokinase plasminogen activator on the basis of its co-migration with reference standard and western blot analysis, and did not vary with labour status. An additional protease with an apparent molecular mass of approximately 90 kDa was detected in all tissues. Densitometric measurement of these tissues showed a significant (P < 0.05) increase in this enzyme activity with labour onset. Heavy metal chelators (1 mmol 1.10 phenanthroline l-1 and 10 mmol EDTA l-1) selectively blocked the 90 kDa activity, consistent with the proposal that it is a metalloprotease. Co-migration with reference standard and western blot analysis confirmed the identity of this protease as the matrix metalloprotease 9 (MMP-9). Immunoreactive MMP-9 protein was also significantly (P < 0.05) increased during and after labour compared with before labour in all tissues examined. It is proposed that the upregulated expression of MMP-9 is involved in fetal membrane rupture and placental separation during and after labour onset, respectively. In conclusion, the regulated repertoire of protease activities expressed by human gestational tissues implies an important role for matrix-degrading enzymes during human parturition.

Patterning capabilities of EUV resists (2004)

EUV photoresists must be developed that meet the stringent patterning requirements for the next-generation of microprocessors (32nm node and beyond). In this paper we will address the ability of EUV photoresists to meet the material targets specs (MTS), such as CD resolution, line width roughness (LWR), photo sensitivity, and absorbance. The challenges of meeting CD resolution and line width roughness specs are not restricted to EUV lithography, but also need to be met by other technologies (193nm, 157nm, and 193 immersion technologies). However, EUV photoresists encounter the unique challenge of meeting these MTS with higher photospeeds than any other lithographic technology due to EUV source requirements. The design of EUV resists that meet all of the MTS and have sufficiently high photospeeds is very challenging. In this paper, we will present experimental results of EUV photoresists patterning results from the 10X tool at Sandia National Lab, and the F2X at Lawrence Berkeley National Lab. Data on resolution, LWR, photo sensitivity, and absorbance are included. Finally we address the capabilities of current EUV resists to meet the patterning requirements, and highlight areas where acceleration is required to meet the Intel roadmap.
Grignard Reactions of 4-Substituted-2-keto-1,3-dioxanes:  Highly Diastereoselective Additions Controlled by a Remote Alkyl Group (2001)

[see reaction]. The reactions of Grignard reagents with a representative series of simple cis-2-keto-4-substituted-1,3-dioxanes have been investigated. The stereochemical outcome of these highly diastereoselective additions (dr > 90:10) is consonant with Cram's chelate model on the assumption that RMgX coordinates preferentially with the ring oxygen remote from the C(4) substituent.
Homooligomeric and Heterooligomeric Associations between K+-Cl– Cotransporter Isoforms and between K+-Cl– and Na+-K+-Cl– Cotransporters (2007)

Little is known regarding the quaternary structure of cation-Cl- cotransporters (CCCs) except that the Na+-dependent CCCs can exist as homooligomeric units. Given that each of the CCCs exhibits unique functional properties and that several of these carriers coexist in various cell types, it would be of interest to determine whether the four K+-Cl- cotransporter (KCC) isoforms and their splice variants can also assemble into such units and, more importantly, whether they can form heterooligomers by interacting with each other or with the secretory Na+-K+-Cl- cotransporter (NKCC1). In the present work, we have addressed these questions by conducting two groups of analyses: 1) yeast two-hybrid and pull-down assays in which CCC-derived protein segments were used as both bait and prey and 2) coimmunoprecipitation and functional studies of intact CCCs coexpressed in Xenopus laevis oocytes. Through a combination of such analyses, we have found that KCC2 and KCC4 could adopt various oligomeric states (in the form of KCC2-KCC2, KCC4-KCC4, KCC2-KCC4, and even KCC4-NKCC1 complexes), that their carboxyl termini were probably involved in carrier assembly, and that the KCC4-NKCC1 oligomers, more specifically, could deploy unique functional features. Through additional coimmunoprecipitation studies, we have also found that KCC1 and KCC3 had the potential of assembling into various types of CCC-CCC oligomers as well, although the interactions uncovered were not characterized as extensively, and the protein segments involved were not identified in yeast two-hybrid assays. Taken together, these findings could change our views on how CCCs operate or are regulated in animal cells by suggesting, in particular, that cation-Cl- cotransport achieves higher levels of functional diversity than foreseen.
A reconfigurable interconnected filter for face recognition based on convolution neural network (2009)

A dynamically reconfigurable hardware model for convolutional neural network (CNN) is presented. The modular prototyping system is based on XILINX FPGAs and is capable of emulating hardware implementations of CNN for the task of face recognition. The system is capable of emulating the complex structure of CNN with exploitation of a small chip area by using the property of reconfiguration. A speedup of about 88 is achieved with FPGA modules of 50 MHz compared to a software implementation on a state of the art personal computer for typical applications of CNN.
