A detailed study of the viscoelastic nature of vapor sorption and transport in a cellulosic polymer. I. Origin and physical implications of deviations from Fickian sorption kinetics (1995)

Abstract Various aspects of the kinetics of sorption of acetone vapor by cellulose acetate films at 30°C have been studied in detail, the principal aim being to understand more thoroughly the physical nature and causes of non‐Fickian behavior in this and other similar polymer‐micromolecular penetrant systems. Particular attention was given to the changes in sorption (including absorption, desorption, and resorption) kinetics caused by (a) systematic variation of the vapor pressure of acetone in different ways and (b) changes in membrane thickness. It has been shown that both viscous volume swelling relaxation and longitudinal differential swelling stress effects must be invoked, in order to explain fully the observed behavior. Detailed analysis of two‐stage sorption kinetics indicated (1) reasonable agreement between estimates of the diffusion coefficient reported by different authors, as long as a consistent analysis of the first stage is used, although the significance of the values given is open to some doubt, because the said first stage is found not to be free of non‐Fickian features; and (2) reasonable conformity of the second stage to a first‐order volume relaxation process (except a long times), with a relaxation frequency strongly dependent on the width of the concentration interval covered by the sorption experiment (and hence on the applied “osmotic stress”). The close similarity of second‐stage sorption to nonlinear viscoelastic creep behavior, previously found in the cellulose‐water system was confirmed and is taken further here, by demonstrating semiquantitative agreement between the corresponding “elastic swelling” and mechanical bulk moduli. ©1995 John Wiley & Sons, Inc.
Minimal-cost-variance power control for differentiated service satellite communications (2016)

It is the aim of this paper to focus on some advanced ideas of power adjustments for differentiated services in satellite communications. Dynamic resource allocation explicitly considers the tradeoff between the cost of transmit powers and the error of signal-to-interference-plus-noise ratios. Achieving maximal system capacity and design for reliability are intertwined and mutually reinforcing goals as being incorporated into the framework of minimal-cost-variance control theory. Closely related to the continuing quest for an effective procedure of availability for satellite communications is a reliable estimation process of terminal reports in presence of interferences and deteriorated link conditions with the hope that these findings would enable future capability concepts of resilient affordable satellite system controllers and ground terminals to achieve assured satellite communications.
Daidzein and genistein but not their glucosides are absorbed from the rat stomach (1999)

Absorption of isoflavone aglycones and glucosides was compared in rats. Daidzein, genistein, daidzin and genistin were orally administered at a dose of 7.9 micromol/kg in 25 mM Na2CO3 and next their metabolite concentration in blood plasma was monitored for 30 min. After isoflavone glucosides administration, their metabolites appeared in plasma with a few minutes delay as compared to aglycones, which suggested that aglycones, but not glucosides, were absorbed already in the rat stomach. This observation was confirmed when absorption site was restricted solely to the stomach and absorption was shown to be independent of the vehicle pH used for administration.

DSP‐type first‐order digital phase‐locked loop using linear phase detector (1986)

Abstract With the development of modern digital technology, phase‐locked loops (PLL) are also becoming digitalized. The digital signal processing (DSP)‐type digital PLL (DPLL) realized by microprocessors and software deserves particular interest. This is because it can be used in time‐sharing operation and its characteristics can easily be controlled. Therefore, it will probably be used widely in digital communication for synchronization and signal conversion circuits. However, up to now, the DSP‐type DPLL has been derived from an analog PLL by directly realizing its operation with DSP methods. Consequently, the generation of distortion components due to the nonlinear characteristic of the phase detection can not be avoided. Moreover, the high‐frequency components arising from the multiplication in the phase detector have a harmful influence on DPLL operation. This paper proposes a new DSP‐type DPLL which eliminates the forementioned disadvantages. This DPLL applies subtraction instead of multiplication in the phase detector to eliminate high‐frequency components. In this way the phase detection linear and does not produce distortion components. Furthermore, it has an AM suppression effect and therefore automatic gain control (AGC) circuit is not needed.
A Method for Syncronous Transmissions with Exposing Terminal on the Basis of Overheating RTS Header Information (2009)

IEEE802.11DCF, which is a most widely used wireless LAN employs RTS/CTS handshake as an option for mitigating effects of hidden terminals. This handshake can prevent packet collisions by exchange RTS and CTS among transmitter and receiver in order to notify length of its transmission period to neighboring terminals. However, by the handshaking, terminals overhearing RTS and/or CTS prohibit its transmission needlessly even though the terminals can transmit packet without any damaging effect for on going transmission. This paper proposes a new method for synchronous parallel transmissions with exposing terminal on the basis of overhearing RTS header information.
Overexpressed Human Mitochondrial Thioredoxin Confers Resistance to Oxidant-induced Apoptosis in Human Osteosarcoma Cells (2002)

Oxidative damage to mitochondria is a central mechanism of apoptosis induced by many toxic chemicals. Thioredoxin family proteins share a conserved Cys-X-X-Cys motif at their active center and play important roles in control of cellular redox state and protection against oxidative damage. In addition to the well studied cytosolic and extracellular form (Trx1), rat and avian mitochondrial forms of thioredoxin (mtTrx) have been reported. In this study, we cloned the full-length human mtTrx cDNA and performed localization and functional studies in 143B human osteosarcoma cells. The coding sequence of human mtTrx consists of a region with homology to Trx1 as well as a putative mitochondrial localization signal (MLS) at its N terminus. In stably transfected cell lines, mtTrx had a mitochondrial localization as measured by subcellular fractionation studies and by confocal fluorescence microscopy. Deletion of the MLS rendered mtTrx to be solely expressed in the cytosolic fraction. On SDS-PAGE, transfected mtTrx had the same apparent molecular weight as the MLS truncated form, indicating that the leader sequence is cleaved during or after mitochondrial import. Treatment with the oxidant tert-butylhydroperoxide induced apoptosis in 143B cells. This oxidant-induced apoptosis was inhibited by overexpressing the full-length mtTrx in 143B cells. Thus, human mtTrx is a member of the thioredoxin family of proteins localized to mitochondria and may play important roles in protection against oxidant-induced apoptosis.

Performance evaluation of beamforming techniques for speech enhancement (2017)

This paper presents speech enhancement using fixed and adaptive beamforming techniques to improve quality of speech signal in noisy environment. Microphone arrays provide a means of enhancing a desired signal in the presence of corrupting noise sources using spatial filtering. In this paper, Delay and Sum Beamformer (DSB) and Generalized Side lobe Canceller (GSC) beamformer are implemented using microphone array and their performance are evaluated by considering various noises under different SNR levels. Enhanced speech characteristics are represented in time domain and frequency domain. The interference is nullified and the beamformer is steered towards desired direction using spatial response. An enhanced speech with improved SNR is achieved by generalized side lobe canceller with Least Mean Square (LMS) algorithm than Delay and Sum beamformer.
A New Constellation Diagram-Based Signal Detection for GSM-MIMO Systems (2017)

The generalized spatial modulation is a multi-input multi-output modulation technique that improves spectral and energy efficiency, but also increases receivers' detection complexity. In this letter, we first propose a new constellation diagram, and then realize: a joint detection of modulated and zero-power signals and a companion detection algorithm based on this new diagram. Simulation results show that our algorithm can achieve near maximum likelihood bit error rate performance and reduce complexity at a maximum rate of 42% compared with the conventional ordered block minimum mean-squared error algorithm.

A large genome scan for rare CNVs in amyotrophic lateral sclerosis (2010)

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease selectively affecting motor neurons in the brain and spinal cord. Recent genome-wide association studies (GWASs) have identified several common variants which increase disease susceptibility. In contrast, rare copy-number variants (CNVs), which have been associated with several neuropsychiatric traits, have not been studied for ALS in well-powered study populations. To examine the role of rare CNVs in ALS susceptibility, we conducted a CNV association study including over 19,000 individuals. In a genome-wide screen of 1875 cases and 8731 controls, we did not find evidence for a difference in global CNV burden between cases and controls. In our association analyses, we identified two loci that met our criteria for follow-up: the DPP6 locus (OR = 3.59, P = 6.6 × 10(-3)), which has already been implicated in ALS pathogenesis, and the 15q11.2 locus, containing NIPA1 (OR = 12.46, P = 9.3 × 10(-5)), the gene causing hereditary spastic paraparesis type 6 (HSP 6). We tested these loci in a replication cohort of 2559 cases and 5887 controls. Again, results were suggestive of association, but did not meet our criteria for independent replication: DPP6 locus: OR = 1.92, P = 0.097, pooled results: OR = 2.64, P = 1.4 × 10(-3); NIPA1: OR = 3.23, P = 0.041, pooled results: OR = 6.20, P = 2.2 × 10(-5)). Our results highlight DPP6 and NIPA1 as candidates for more in-depth studies. Unlike other complex neurological and psychiatric traits, rare CNVs with high effect size do not play a major role in ALS pathogenesis.
Interactive learning and probabilistic retrieval in remote sensing image archives (2000)

The authors present a concept of interactive learning and probabilistic retrieval of user-specific cover types in a content-based remote sensing image archive. A cover type is incrementally defined via user-provided positive and negative examples. From these examples, the authors infer probabilities of the Bayesian network that link the user interests to a pre-extracted content index. Due to the stochastic nature of the cover type definitions, the database system not only retrieves images according to the estimated coverage but also according to the accuracy of that estimation given the current state of learning. For the latter, they introduce the concept of separability. They expand on the steps of Bayesian inference to compute the application-free content index using a family of data models, and on the description of the stochastic link using hyperparameters. In particular, they focus on the interactive nature of their approach, which provides instantaneous feedback to the user in the form of an immediate update of the posterior map, and a very fast, approximate search in the archive. A java-based demonstrator using the presented concept of content-based access to a test archive of Landsat TM, X-SAR, and aerial images are available over the Internet [http:/www.vision.ee.ethz.ch/-rsia/ClickBayes].
A Theory-Driven Design Framework for Social Recommender Systems (2010)

Social recommender systems utilize data regarding users’ social relationships in filtering relevant information to users. To date, results show that incorporating social relationship data – beyond consumption profile similarity – is beneficial only in a very limited set of cases. The main conjecture of this study is that the inconclusive results are, at least to some extent, due to an under-specification of the nature of the social relations. To date, there exist no clear guidelines for using behavioral theory to guide systems design. Our primary objective is to propose a methodology for theory-driven design. We enhance Walls et al.’s (1992) IS Design Theory by introducing the notion of “applied behavioral theory,” as a means of better linking theory and system design. Our second objective is to apply our theory-driven design methodology to social recommender systems, with the aim of improving prediction accuracy. A behavioral study found that some social relationships (e.g., competence, benevolence) are most likely to affect a recipient’s advice-taking decision. We designed, developed, and tested a recommender system based on these principles, and found that the same types of relationships yield the best recommendation accuracy. This striking correspondence highlights the importance of behavioral theory in guiding system design. We discuss implications for design science and for research on recommender systems.
Programmable memory BIST and a new synthesis framework (2003)

The development of two programmable memory BIST architectures is first reported. A memory synthesis framework which can automatically generate, verify and insert programmable as well as non-programmable BIST units is developed as a vehicle to efficiently integrate BIST architectures in today's memory-intensive systems. Custom memory test algorithms could be loaded in the developed programmable BIST unit and therefore any type of memory test algorithm could be realized. The flexibility and efficiency of the framework are demonstrated by showing that these memory BIST units could be generated, functionally verified and inserted in a short time.
57 PARENTERAL CHROMIUM TOXICITY IN NEWBORNS RECEIVING PARENTERAL NUTRITION. (1996)

Our previous study (The Lancet 1992; 339: 385-388) suggested that the recommended dose of chromium for children receiving TPN was too high. Even though the children were receiving less than the recommended daily parenteral intake of chromium, their serum chromium concentrations were 20 times higher than those in non-TPN controls. The TPN recipients had lower than normal glomerular filtration rates which were inversely correlated with indices of chromium intake. No study has been conducted in premature and newborn infants. We hypothesized that these infants who have a low GFR at birth as compared to older children, are even at greater risk for chromium toxicity. In a randomized blinded prospective protocol, we studied chromium intake and renal function in 60 (40 male) premature and full-term newborns receiving TPN for more than 3 weeks. They were randomly assigned to receive either no chromium (group 1; n= 31) or the recommended dose of 0.2 mcg/kg/day (group 2; n=29) in the TPN solution. The two groups were not statistically different by weight, length, indications for and duration of the TPN, daily intake of calories, nutrients, antibiotic or diuretic use. Overtime, there was no difference in the BUN levels, but a progressive decrease in serum creatinine level in both groups. In group 2, the creatinine level (0.51 ± 0.16) at 3 weeks became significantly higher than that of group 1 (0.41 ± 0.14; p<0.04). This trend continued untill the end of the study (at 5 weeks: 0.38 ± 0.13 in group 2 v/s 0.27 ± 0.12 in group 1., p < 0.03). We conclude that newborns receiving the “recommended” amount of parenteral chromium exhibit higher serum creatinine values than infants receiving placebo. This difference becomes significant within 3 weeks. The clinical significance of our findings is unknown at the present time, raising the issue of reversibility. Further studies are needed for the determination of the optimal dose of parenteral chromium.
High laser-resistant multilayer mirrors by nodular defect planarization [Invited] (2014)

Substrate defect planarization has been shown to increase the laser resistance of 1053 nm mirror coatings to greater than 100 J/cm2, an increase of 20-fold, when tested with 10 ns laser pulses. Substrate surface particles that are overcoated with optical interference mirror coatings become nodular defects, which behave as microlenses intensifying light into the defect structure. By a discrete process of angle-dependent ion etching and unidirectional ion-beam deposition, substrate defects can be reduced in cross-sectional area by over 90%.

ELHFR: A graph routing in industrial wireless mesh network (2009)

Graph routing is proposed in wirelessHART communication foundation, but the implementing of the algorithm is not specified. This paper proposes a graph routing mechanism termed ELHFR (EXHENCED LEAST-HOP FIRST ROUTING) that exploits the mesh topology and application characteristics of wirelessHART. ELHFR defines the network topology as a connected graph then generates the sub-graph that includes all the shortest paths from a node to the given destination. ELHFR does not need find the shortest paths of all nodes in the network, but only of the special nodes that are leaves of a breadth first tree. After several sub-graphs of topology graph are generated, the shortest paths to the destination of ever node can be found in them. The routing generating algorithm is presented in detail, as well as the routing updating mechanism. We analyze the ELFHR to provide intuitive understanding of its performance, and simulate it in OMNet++ subsequently. The simulation result shows that significant improvement over AODV routing in aspects of reliability and stability, which are the important requirements of industrial wireless network.
