Bacterial Catalase in the Microsporidian <i>Nosema locustae</i> : Implications for Microsporidian Metabolism and Genome Evolution (2003)

Microsporidia constitute a group of extremely specialized intracellular parasites that infect virtually all animals. They are highly derived, reduced fungi that lack several features typical of other eukaryotes, including canonical mitochondria, flagella, and peroxisomes. Consistent with the absence of peroxisomes in microsporidia, the recently completed genome of the microsporidian Encephalitozoon cuniculi lacks a gene for catalase, the major enzymatic marker for the organelle. We show, however, that the genome of the microsporidian Nosema locustae, in contrast to that of E. cuniculi, encodes a group II large-subunit catalase. Surprisingly, phylogenetic analyses indicate that the N. locustae catalase is not specifically related to fungal homologs, as one would expect, but is instead closely related to proteobacterial sequences. This finding indicates that the N. locustae catalase is derived by lateral gene transfer from a bacterium. The catalase gene is adjacent to a large region of the genome that appears to be far less compact than is typical of microsporidian genomes, a characteristic which may make this region more amenable to the insertion of foreign genes. The N. locustae catalase gene is expressed in spores, and the protein is detectable by Western blotting. This type of catalase is a particularly robust enzyme that has been shown to function in dormant cells, indicating that the N. locustae catalase may play some functional role in the spore. There is no evidence that the N. locustae catalase functions in a cryptic peroxisome.
Digital business: Using data in decision making (2018)

Analysis of data with business analytics is an integral component of a successful organizational digital trans-formation strategy.14 Business analytics refers to a set of innovative tools and techniques used to generate insights from large, diverse data sets. The use of analytics can offer individuals, organizations, govern-ments, and the global society "data-based" perspectives on existing challenges and possible solutions. Analysis can potentially provide facts to improve data-based decision making. Business and data analytics help find meaning in an increasingly complex environment.
Design of a planar antenna with G-shaped rings for WLAN/ WiMAX (2011)

A compact antenna for WLAN/WiMAX is presented in this paper. By combining two G-shaped rings with a planar monopole antenna, the proposed antenna with the small size of 43mm×12mm×0.8mm provides a wide bandwidth of 2.4/5.2/5.8GHz WLAN bands and the 2.5/5.2 GHz WiMAX bands. Good dipole-like simulated radiation characteristics over the operating bands are obtained.
Genetic Screening for Prey in the Gut Contents from a Giant Squid (Architeuthis sp.) (2005)

Giant squids (Architeuthis sp.) remain mysterious; they have evaded observation and are rarely taken from their deep sea habitat. Information on the diet of Architeuthis is scarce due to the limited number of specimens with morphologically recognizable remains in their digestive tracts. We explored the use of polymerase chain reaction (PCR)-based methods for detection of DNA in the prey remains and amorphous slurry from an Architeuthis gut sample. The DNA region amplified varied in size, allowing separation of fish and squid components. Sequence comparisons identified fish prey as Macruronus novaezelandiae. Isolation of Architeuthis DNA from an ingested tentacle and the presence of chitin fragments indicate cannibalism occurs in giant squid. Denaturing gradient gel electrophoresis was used to screen for less common DNA types, revealing a high frequency of PCR-generated false alleles, but no additional prey species.
High-mobility vertical transport in graded-gap GaAs/AlGaAs superlattices (1987)

In compositionally graded superlattices, grown by molecular beam epitaxy, the carrier mobilities in the direction perpendicular to the layers have been experimentally estimated in an 'all-optical' experiment. Mobilities in low-period graded-gap superlattices are estimated to be greater than those of AlGaAs graded-gap alloys.

Component-wise optimization for a commercial central cooling plant (2011)

Thermal comfort and energy savings are two main goals of heating, ventilation and air conditioning (HVAC) systems. In this paper, the optimization-simulation approach is proposed for effective energy saving potential in a commercial central cooling plant by refining the model of optimal operation for system components and deriving optimal conditions for their operation subject to technical and human comfort constraints. To investigate the potential of energy savings and air quality, a real-world commercial building, located in a hot and dry climate region, together with its central cooling plant is used for experimentation and data collection. Both inputs and outputs of the existing central cooling plant are measured from the field monitoring in one typical week in the summer. Optimization is performed by using empirically-based models of the central cooling plant components. Optimization algorithms implemented on a transient simulation software package, are used to solve the minimization problem of energy consumption for each considered control strategies and predict the HVAC system optimized set-points under transient load. The integrated simulation tool was validated by comparing predicted and measured power consumption of the chiller during the first day of July. Results show that between 3.2% and 11.8% power savings can be obtained by this approach while maintaining the predicted mean vote (PMV) from -0.5 to +1 for most of the summer time.

An improved deep level transient spectroscopy method (1988)

An examination of the DLTS (deep level transient spectroscopy) technique suggests a new method for analyzing data for DLTS signal intensity S(T) as a function of temperature T. It is shown that the low-temperature asymptotic slope of a plot of ln S(T) vs 1/T yields the activation energy for deep level emission rates. Thus, in the new method, deep level energies are obtained from one run at a given rate window in contrast with traditional DLTS for which several runs at various rate windows are needed to obtain the same information.
Determination of CYP2D6 Gene Copy Number by Pyrosequencing (2005)

CYP2D6 gene copy determination by Pyrosequencing is a reliable and rapid alternative to other methods. The use of an internal CYP2D8P control as well as generation of a sequence context ensures a robust method and hence facilitates method validation.
Guided wave propagation based damage detection in welded rectangular tubular structures (2009)

Guided wave based methods have shown great potential to practical use and have been the object of many researches for structural health monitoring (SHM). In this paper, a welded steel structure with rectangular section, which is almost 1:1 scale model for a bogie frame segment of train, is investigated by using both finite element method (FEM) and experimental analysis for the purpose of damage detection. Finite element models are established to simulate the propagation behavior of guided waves in the structure. An active actuator/sensor network is employed to generate guided waves propagating in the structures and collect response signals. Excitations at selected frequency are used to minimize the effect of the intrinsic multi-mode phenomenon of guided waves on the consequent signal interpretation. Modern signal processing approaches, such as continuous wavelet transform (CWT) and Hilbert transform (HT), are applied to all collected signals. An algorithm based on the concept of damage presence probability (DPP) is proposed for estimation of damage location. The results indicate that the recommended guided wave propagation based approach is reasonable for damage detection in such kind of structures.
Effect of diabetes and fasting on GLUT-4 (muscle/fat) glucose-transporter expression in insulin-sensitive tissues. Heterogeneous response in heart, red and white muscle (1992)

1. GLUT-4 glucose-transporter protein and mRNA levels were assessed in heart, red muscle and white muscle, as well as in brown and white adipose tissue from 7-day streptozotocin-induced diabetic and 48 h-fasted rats. 2. In agreement with previous data, white adipose tissue showed a substantial decrease in GLUT-4 mRNA and protein levels in response to both diabetes and fasting. Similarly, GLUT-4 mRNA and protein markedly decreased in brown adipose tissue in both insulinopenic conditions. 3. Under control conditions, the level of expression of GLUT-4 protein content differed substantially in heart, red and white skeletal muscle. Thus GLUT-4 protein was maximal in heart, and red muscle had a greater GLUT-4 content compared with white muscle. In spite of the large differences in GLUT-4 protein content, GLUT-4 mRNA levels were equivalent in heart and red skeletal muscle. 4. In heart, GLUT-4 mRNA decreased to a greater extent than GLUT-4 protein in response to diabetes and fasting. In contrast, red muscle showed a greater decrease in GLUT-4 protein than in mRNA in response to diabetes or fasting, and in fact no decrease in GLUT-4 mRNA content was detectable in fasting. On the other hand, preparations of white skeletal muscle showed a substantial increase in GLUT-4 mRNA under both insulinopenic conditions, and that was concomitant to either a modest decrease in GLUT-4 protein in diabetes or to no change in fasting. 5. These results indicate that (a) the effects of diabetes and fasting are almost identical and lead to changes in GLUT-4 expression that are tissue-specific, (b) white adipose tissue, brown adipose tissue and heart respond similarly to insulin deficiency by decreasing GLUT-4 mRNA to a larger extent than GLUT-4 protein, and (c) red and white skeletal muscle respond to insulinopenic conditions in a heterogeneous manner which is characterized by enhanced GLUT-4 mRNA/protein ratios.
Fabrication of nanoporous graphene/polymer composite membranes (2017)

Graphene is currently investigated as a promising membrane material in which selective pores can be created depending on the requirements of the application. However, to handle large-area nanoporous graphene a stable support material is needed. Here, we report on composite membranes consisting of large-area single layer nanoporous graphene supported by a porous polymer. The fabrication is based on ion-track nanotechnology with swift heavy ions directly creating atomic pores in the graphene lattice and damaged tracks in the polymer support. Subsequent chemical etching converts the latent ion tracks in the supporting polymer foil, here polyethylene terephthalate (PET), into open microchannels while the perfectly aligned pores in the graphene top layer remain unaffected. To avoid unintentional damage creation and delamination of the graphene layer from the substrate, the graphene is encapsulated by a protecting poly(methyl methacrylate) (PMMA) layer. By this procedure a stable composite membrane is obtained consisting of nanoporous graphene (coverage close to 100%) suspended across selfaligned track-etched microchannels in a polymer support film. Our method presents a facile way to create high quality suspended graphene of tunable pore size supported on a flexible porous polymeric support, thus enabling the development of membranes for fast and selective ultrafiltration separation processes.
Self-quotient Image (2005)

This paper presents an analysis of Retinex and its relations to the quotient image (QI),and proposes a novel concept,called the self-quotient image (SQI),for extraction of intrinsic image property of an object such as the face while removing extrinsic factors corresponding to the illumination.The SQI overcomes limitations of the original QI method and is able to extract the intrinsic property.It performs a theoretical analysis of conditions when the algorithm applies.A non-iterative filtering algorithm is presented for SQI calculation.The experiment results show the effectiveness of the method for face recognition under various lighting conditions.
Plastic deformation of microstructures using carbon nanotubes film as latching surface (2011)

We have demonstrated a novel method utilizing carbon nanotube (CNT) arrays as latching surface for silicon plastic deformation applications where the high temperature process is required. The CNT arrays integrated on microstructures maintain the strained shapes of the microstructures in the high temperature environments. In order to demonstrate the proposed method, arrays of angular vertical comb-drive (AVC) actuators were successfully fabricated by the silicon plastic deformation process while the CNTs anchored the strained microstructures. After the process, the CNTs were fully removable by thermal oxidation. The proposed method could be applied to diverse microelectromechanical systems (MEMS) for microscale assembly and harsh environment processing.
The NCEP Mesoscale Spectral Model: A Revised Version of the Nonhydrostatic Regional Spectral Model (2000)

This paper illustrates a modified nonhydrostatic version of the National Centers for Environmental Prediction regional spectral model (RSM). This nonhydrostatic version of the RSM can simulate atmospheric motions of all scales, especially mesoscale. For simplicity, it is referred to in this paper as the mesoscale spectral model (MSM). The preliminary results of the previous version of the MSM have been published on the year of 1992, with coarse resolution in three dimensions and no model physics. A fine-resolution two-dimensional version has been tested on classical problems and published on the year of 1994. Instead of an externally determined hydrostatic coordinate as originally designed in 1992 MSM, the internally evolved hydrostatic coordinate as used in the RSM is implemented. This modification makes the MSM closer to the hydrostatic version in model structure and dynamics. Besides the hydrostatic perturbation, related to the external hydrostatic state as perturbation nesting, the nonhydrostatic perturbation related to the internally evolved hydrostatic state is introduced. The same model physics used in the RSM are used in the MSM without the hydrostatic assumption. The major numerical techniques used in the hydrostatic version are used in the MSM as well. They are spectral computation, fourth-order horizontal diffusion, time filter, and semi-implicit adjustment for perturbation. The hydrostatic state, interpolated from the hydrostatic global model, is used as the initial condition without initialization or data assimilation, and it can be integrated up to several days with reasonable predictions. Extended tests of thermal bubbles and mountain waves in very fine resolutions by this revised MSM showed its behavior to be the same as, but not superior to, those of the previous version. These results are compatible to other model results in the literature. Cases using real data with full model physics as used in the RSM show that the revised MSM has reasonable results and is superior to the previous version as compared with the RSM in a coarse horizontal grid resolution of about 50 km. Furthermore, it shows that it can be successfully nested into the hydrostatic global model at 10- to 20-fold differences in horizontal resolution with a small domain due to the well-behaved perturbation nesting over flat plains, coastal oceans, and steep mountains.
Time recovery through fusion of inaccurate network timing assistance with GPS measurements (2000)

Fusion of inadequate timing information from GPS space vehicles and from a cellular network is studied. Neither of the sources is accurate enough to be used for exact timing alone, but using the time recovery method proposed by the author, exact timing can be eventually derived from the fusion of these sources. Naturally, the positioning accuracy is also positively affected when accurate time is recovered. The proposed method is based on minimization of a quality of fit value. The quality of fit value used in the paper is the sum of squared residuals obtained from a least mean squares based positioning solution, widely used in point-solution type GPS applications. The proposed method is tested and its performance is demonstrated using both simulated and real data.

Catalytic Steam Methane Reforming Over Ir/Ce<sub>0.9</sub>Gd<sub>0.1</sub>O<sub>2–</sub><sub><i>x</i></sub>: Resistance to Coke Formation and Sulfur Poisoning (2011)

Abstract This work investigates the catalytic properties of Ir/Ce 0.9 Gd 0.1 O 2– x (Ir/CGO) catalyst and CGO support in steam reforming of methane in the absence or presence of H 2 S (50 ppm) for further application in a solid oxide fuel cell (SOFC) working under methane at intermediate temperatures and integrating a gradual internal reforming concept. The catalytic activity was measured at 750 °C by using a 50 mol.% CH 4 /5 mol.% H 2 O/45 mol.% N 2 mixture and a 10 mol.% CH 4 /90 mol.% N 2 mixture. The addition of Ir to CGO improves the catalytic activity in hydrogen production by two orders of magnitude with respect to that of CGO alone. Temperature programmed oxidation experiments were performed after reaction in both types of mixtures to study the eventual formation of carbon deposits. Over Ir/CGO, carbon formed in little amounts (even in the absence of H 2 O in the feed), being highly reactive toward O 2 . Upon H 2 S addition, the CGO support exhibited surprisingly an improved catalytic activity on the contrary to Ir/CGO which partly deactivated. Upon suppression of H 2 S in the feed the initial catalytic activity was fully restored for both catalysts. The catalytic behavior of CGO in the presence of H 2 S was discussed, based upon temperature programmed reaction of CH 4 .
Measurement of triboluminescence and proton half brightness dose for ZnS:Mn (2004)

Preliminary research has shown that triboluminescent (TL) phosphors show promise for use as the active element in impact sensors. For ZnS:Mn, preliminary results indicate that impact energies greater than 1.6/spl times/10/sup -2/ J produced measurable TL light. A so-called "smart" structure with embedded TL material could be capable of determining whether a particle had struck, and record the relative intensity of its impact. In order to use such materials in space, we need to understand the radiation susceptibility of the TL phosphor. The corresponding proton dose required to reduce the proton-induced luminescence of ZnS:Mn to half of its initial value was found to be 9.02/spl times/10/sup 13/ mm/sup -2/. This value will be used to help determine how incident protons affect the production of TL in ZnS:Mn.
Constructing Scalable Overlays for Pub-Sub with Many Topics Problems, Algorithms, and Evaluation (2008)

We investigate the problem of designing a scalable overlay network to support decentralized topic-based pub/sub communication. We introduce a new optimization problem, called Minimum Topic-Connected Overlay (Min-TCO), that captures the tradeoff between the scalability of the overlay (in terms of the nodes ’ fanout) and the message forwarding overhead incurred by the communicating parties. Roughly, the Min-TCO problem is as follows: Given a collection of nodes and their subscriptions, connect the nodes using the minimum possible number of edges so that for each topic t, a message published on t could reach all the nodes interested in t by being forwarded by only the nodes interested in t. We show that the decision version of Min-TCO is NPcomplete, and present a polynomial algorithm that approximates

Graph data partition models for online social networks (2012)

Online social networks have become important vehicles for connecting people for work and leisure. As these networks grow, data that are stored over these networks also grow, and management of these data becomes a challenge. Graph data models are a natural fit for representing online social networks but need to support distribution to allow the associated graph databases to scale while offering acceptable performance. We provide scalability by considering methods for partitioning graph databases and implement one within the Neo4j architecture based on distributing the vertices of the graph. We evaluate its performance in several simple scenarios and demonstrate that it is possible to partition a graph database without incurring significant overhead other than that required by network delays. We identify and discuss several methods to reduce the observed network delays in our prototype.
