Linear phase paraunitary filter banks: theory, factorizations and designs (1993)

M channel maximally decimated filter banks have been used in the past to decompose signals into subbands. The theory of perfect-reconstruction filter banks has also been studied extensively. Nonparaunitary systems with linear phase filters have also been designed. The authors study paraunitary systems in which each individual filter in the analysis synthesis banks has linear phase. Specific instances of this problem have been addressed by other authors, and linear phase paraunitary systems have been shown to exist. This property is often desirable for several applications, particularly in image processing. They begin by answering several theoretical questions pertaining to linear phase paraunitary systems. Next, they develop a minimal factorization for a large class of such systems. This factorization will be proved to be complete for even M. Further, they structurally impose the additional condition that the filters satisfy pairwise mirror-image symmetry in the frequency domain. This significantly reduces the number of parameters to be optimized in the design process. They then demonstrate the use of these filter banks in the generation of M-band orthonormal wavelets. Several design examples are also given to validate the theory.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Identification, subcellular localization, and developmental studies of oleosins in the anther of <i>Brassica napus</i> (1997)

mRNAs encoding putative oleosins have been detected in the tapetum of developing anthers in Brassica and Arabidopsis, but the authentic proteins have not been previously documented. Antibodies against a synthetic 15-residue polypeptide that represents a portion of the putative tapetum oleosins encoded by two cloned Brassica napus genes were raised. Using these antibodies for immunoblotting after SDS-PAGE of the sporophytic extracts of B. napus developing anthers, two oleosins of approximately 48 and 45 kDa were detected. These two oleosins were judged to be the putative oleosins encoded by cloned Brassica genes because of their identical N-terminal sequences. The two oleosins were present in the anthers only during the developmental stage when the tapetum cells were packed with organelles. A fraction of lowdensity organelles was isolated from the developing anthers by flotation centrifugation. The fraction contained plastoglobule-filled plastids and lipid-containing particles. The structures of these two isolated organelles were similar to those in situ in the tapetum cells. Of subcellular fractions of the anther homogenate, the two oleosins were present exclusively in the low-density organelle fraction. They were absent in the surface fractions of the developing microspores and the mature pollen, although fragmented oleosin molecules were earlier reported to be present on the pollen. By immunocytochemistry, immunogold particles were found largely on the periphery of the plastoglobuli inside the plastids in the tapetum cells. The antibodies also detected oleosins on the surface of storage oil bodies inside the maturing microspores. Apparently, the gametophytic microspore oil-body oleosins share common epitopes at the generally non-conserved C-terminal domain with the sporophytic tapetum oleosins.
Assessing passenger feedback reliability in crowd-sourced measurement of transit ride quality (2017)

Transit ride quality is important for everyday commuters to keep using public transportation as a preferred mode of travel. Despite well paved and maintained roads, sophisticated buses and modern bus control and monitoring systems, bus passengers, especially standing passengers, are frequently subjected to braking and acceleration actions along the way and sway discomforts along the curves. Modern buses come with rather powerful braking systems that are sensitive to slightest pressure on brakes by drivers. Passenger injuries as well as complaints increase as such. When crowd sourcing via using smartphone apps is employed, anyone ranging from a child to senior citizen can access and register a complaint about a discomfort moment along bus rides. Filtering genuine complaints is a challenge. We study a basic case of a person registering discomfort in a bus ride using the smartphone app developed for this purpose. At the back-end, the app keeps collecting sensor data. Findings provide a basis for developing machine-learning algorithms for big-data analytics of passenger feedback at a large-scale. A proof-of-concept program written based on study findings was used to show how discomfort data can be authenticated and classified.
Complexity-aware live streaming system (2005)

The number of client requests that a streaming server can handle is limited by both its computational resources and available bandwidth. While bandwidth capacity is critical for most streaming applications, computational resources for a server encoding live videos often become a critical factor as well. In order to serve more client requests or provide higher quality for high priority clients, it is desirable to allocate and adjust the computational resources on a per channel basis. In this paper, we proposed a complexity-aware live video streaming server system that manages the computational resources dynamically. In the proposed system, input videos are encoded with different quality levels based on their priorities and available computational resources. The computational resources for each encoder are adaptively allocated to match the time constraints. The seven quality levels defined in the XviD MPEG-4 encoder are used in our experiments. The results show that the new design is able to maximize the resource utilization by maintaining the highest priority channels quality while providing the other channels with best-effort quality.
Cloning and expression of three abrin A‐chains and their mutants derived by site‐specific mutagenesisin <i>Escherichia coli</i> (1994)

DNAs encoding of three abrin A-chains were obtained from the cDNA library of Abrus precatorius by polymerase chain reaction and ligated into the expression vector, pGEX-2T. The mature A-chains of abrins a, b and d have been expressed in the cytoplasm of Escherichia coli, and the yield of the soluble recombinant proteins was 7 mg/l induced culture. Three recombinant abrin A-chains were purified to be homogeneity and their N-glycosidase ability to inhibit protein biosynthesis in a cell-free system and to depurinate 28S rRNA in rat liver ribosomes was demonstrated in vitro. The recombinant abrin-a A-chain had the highest N-glycosidase activity among three recombinant abrin A-chains while the recombinant abrin-b A-chain, the least. Three mutants, glutamic-acid-to-alanine replacement (E164A), arginine to leucine (R167L) or double mutation (E164A and R167L) were constructed and expressed. The protein-biosynthesis-inhibitory activity of mutant (E164A), mutant (R167L) and the double mutant was found to be 25-fold, 625-fold and 1250-fold lower than that of wild type, respectively. The results indicated that Arg167 was essential for abrin toxin A-chain catalysis.
Parameter sensitivity analysis of nonlinear piezoelectric probe in tapping mode atomic force microscopy for measurement improvement (2014)

The equations of motion for a piezoelectric microcantilever are derived for a nonlinear contact force. The analytical expressions for natural frequencies and mode shapes are obtained. Then, the method of multiple scales is used to analyze the analytical frequency response of the piezoelectric probe. The effects of nonlinear excitation force on the microcantilever beam's frequency and amplitude are analytically studied. The results show a frequency shift in the response resulting from the force nonlinearities. This frequency shift during contact mode is an important consideration in the modeling of AFM mechanics for generation of more accurate imaging. Also, a sensitivity analysis of the system parameters on the nonlinearity effect is performed. The results of a sensitivity analysis show that it is possible to choose parameters such that the frequency shift minimizes. Certain parameters such as tip radius, microcantilever beam dimensions, and modulus of elasticity have more influence on the nonlinearity of the system than other parameters. By changing only three parameters—tip radius, thickness, and modulus of elasticity of the microbeam—a more than 70% reduction in nonlinearity effect was achieved.
Evolutionary spectral clustering by incorporating temporal smoothness (2007)

Evolutionary clustering is an emerging research area essential to important applications such as clustering dynamic Web and blog contents and clustering data streams. In evolutionary clustering, a good clustering result should fit the current data well, while simultaneously not deviate too dramatically from the recent history. To fulfill this dual purpose, a measure of temporal smoothness is integrated in the overall measure of clustering quality. In this paper, we propose two frameworks that incorporate temporal smoothness in evolutionary spectral clustering. For both frameworks, we start with intuitions gained from the well-known k-means clustering problem, and then propose and solve corresponding cost functions for the evolutionary spectral clustering problems. Our solutions to the evolutionary spectral clustering problems provide more stable and consistent clustering results that are less sensitive to short-term noises while at the same time are adaptive to long-term cluster drifts. Furthermore, we demonstrate that our methods provide the optimal solutions to the relaxed versions of the corresponding evolutionary k-means clustering problems. Performance experiments over a number of real and synthetic data sets illustrate our evolutionary spectral clustering methods provide more robust clustering results that are not sensitive to noise and can adapt to data drifts.

Chemoprevention of Barley and Sage against acrylamide-Induced genotoxic, biochemical and histopathological alterations in rats (2004)

Acrylamide (ACR) has recently been found in fried and backed foods, suggesting widespread public exposure. ACR is an industrial chemical material that causes neurotoxicity in humans and was designated as a probable human carcinogen by IARC and USEPA. The aim of the present study was to evaluate the protective effects of barley and sage against ACR mutagenicity and biochemical and histopathological changes in rats. Forty mature male rats were divided into eight groups and were fed barley and/or sage-supplemented diet (5%) with or without ACR (50 mg/kg b.w). The biochemical results revealed that ACR increased Alanine amino transferase (ALT), Aspartate amino transferase (AST), triglycerides (TG), cholesterol and uric acid. Micronucleated polychromatic erythrocytes and chromosomal aberrations in somatic and germ cells were significantly increased in ACR-treated animals. Severe pathological lesions included testicular degeneration, oedema, spermatid giant cells formation and necrosis of spermatid cells were found in the testis of ACR-treated group. The kidney of this group showed degenerative changes. Cotreatment with barley and/or Sage and ACR resulted in a significant improvement in all the parameters tested. It could be concluded that these plants contain antioxidant compounds and may be useful when add as food additive to the food cooked on a higher temperature.
Flavour compounds in tomato fruits: identification of loci and potential pathways affecting volatile composition (2008)

The unique flavour of a tomato fruit is the sum of a complex interaction among sugars, acids, and a large set of volatile compounds. While it is generally acknowledged that the flavour of commercially produced tomatoes is inferior, the biochemical and genetic complexity of the trait has made breeding for improved flavour extremely difficult. The volatiles, in particular, present a major challenge for flavour improvement, being generated from a diverse set of lipid, amino acid, and carotenoid precursors. Very few genes controlling their biosynthesis have been identified. New quantitative trait loci (QTLs) that affect the volatile emissions of red-ripe fruits are described here. A population of introgression lines derived from a cross between the cultivated tomato Solanum lycopersicum and its wild relative, S. habrochaites, was characterized over multiple seasons and locations. A total of 30 QTLs affecting the emission of one or more volatiles were mapped. The data from this mapping project, combined with previously collected data on an IL population derived from a cross between S. lycopersicum and S. pennellii populations, were used to construct a correlational database. A metabolite tree derived from these data provides new insights into the pathways for the synthesis of several of these volatiles. One QTL is a novel locus affecting fruit carotenoid content on chromosome 2. Volatile emissions from this and other lines indicate that the linear and cyclic apocarotenoid volatiles are probably derived from separate carotenoid pools.
Resilient Service Embedding in IoT Networks (2020)

The Internet of Things (IoT) can support a significant number of services including those in smart homes and the automation of industries and public utilities. However, the growth of these deployments has posed a significant challenge especially in terms of how to build such deployments in a highly resilient manner. The IoT devices are prone to unpredicted failures and cyber-attacks, i.e. various types of damage, unreliable wireless connections, limited transmission power, computing ability, and storage space. Thus resilience is essential in IoT networks and in the services they support. In this paper, we introduce a new approach to resilience in IoT service embedding, based on traffic splitting. Our study assesses the power consumption associated with the services embedded and the data delivery time. The results are compared to recent approaches in resilience including redundancy and replication approaches. We constructed an optimization model whose goal is to determine the optimum physical resources to be used to embed the IoT virtual topology, where the latter is derived from a business process (BP). The embedding process makes use of the service-oriented architecture (SOA) paradigm. The physical resources of interest include IoT links and devices. The model made use of mixed integer linear programming (MILP) with an objective function that aimed to minimize both the total power consumption and the traffic latency. The optimization results show that the power consumption is reduced and the data delivery time is reduced in the service embedding approach where the proposed traffic splitting approach is employed resulting in the selection of energy efficient nodes and routes in the IoT network. Our methods resulted in up to 35% power saving compared to current methods and reduced the average traffic latency by up to 37% by selecting energy-efficient nodes and routes in IoT networks and by optimizing traffic flow to minimize latency.

Permutation methods: a distance function approach (2002)

The book will provide a comprehensive treatment of statistical inference using permutation techniques. Its purpose is to make available to practitioners a variety of useful and powerful data analytic tools that rely on very few distributional assumptions. Although many of these procedures have appeared in journal articles, they are not readily available to practitioners.
Dimethylamination and Nitrosation of Pyrimidines with N-Nitrosodimethylamine (1973)

Reaction of a chloropyrimidine and a 5-activated pyrimidine in N-nitrosodimethylamine (NDA) resulted in the simultaneous formation of a dimethylaminopyrimidine and a 5-nitrosopyrimidine which is further transformed. A special type of Vilsmeier-Haack reaction using a mixture of NDA and phosphorus oxychloride (NDA+POCl3) for 5-activated pyrimidines has been accomplished. The reaction of 6-amino-1, 3-dimethyluracil with NDA+POCl3 under cooling gave bis (6-amino-1, 3-dimethyluracil-5-yl) methane, which was converted into 1, 3, 7, 9-tetramethyl (1H, 3H, 7H, 9H)-pyrido [2, 3-d, 6, 5-d'] dipyrimidine-2, 4, 6, 8-tetrone.
PRIME Interoperability Tests and Results from Field (2010)

PRIME (PoweRline Intelligent Metering Evolution) is one of the prominent upcoming powerline communication technologies, targeted for use in smart metering applications. The PRIME PHY / MAC specifications are open, publicly available and are developed by the PRIME Alliance, an industry consortium that includes utilities, meter vendors and semiconductor suppliers. PRIME employs OFDM modulation in the CENELEC A band (9 - 95 kHz), and achieves data rates from 21 kbps to 128 kbps at the PHY layer. The PRIME MAC is optimized for tree- topology networks, and features a novel node discovery and network building process. PRIME converges to IPv4 and IEC 61334-4-32 at the network layer, and is evolving to support IPv6. In this paper, we describe the PRIME Alliance, and review technical details of the PRIME PHY and MAC. We review the certification and interoperability tests defined by the PRIME Alliance, to ensure openness and future-proof technical performance with multi-vendor solutions. We present some initial results from small-scale PRIME field deployments.
Transdermal Application of Myelin Peptides in Multiple Sclerosis Treatment (2013)

pH Independent Nano-Optode Sensors Based on Exhaustive Ion-Selective Nanospheres (2014)

Bulk optode-based ion selective optical sensors work on the basis of extraction equilibria, and their response toward the analyte ion is known to dependent on the sample pH. This pH dependence has been one of the major disadvantages that have hampered the broad acceptance of bulk optodes in chemical sensing. We present here for the first time the use of exhaustive Ca(2+)-selective nanosensors that may overcome this pH dependent response. The nanosensors were characterized at different pH and the same linear calibration was obtained in the Ca(2+) concentration range from 10(-7) M to 10(-5) M.
Efficient, High-Yield Route to Long, Functionalized<i>p</i>-Phenylene Oligomers Containing Perfluorinated Segments, and Their Cyclodimerizations by Zirconocene Coupling (2001)

Linear oligophenylene diynes containing 6, 9, and 12 phenylene rings were synthesized in high yields using the nucleophilic aromatic substitution (S(N)Ar) of perfluoroarenes by aryllithium reagents as the key carbon-carbon bond-forming reaction. This reaction was demonstrated to proceed readily at low temperatures with sterically hindered substrates and in the presence of base-sensitive silylalkynyl groups. Diynes synthesized by this methodology were readily zirconocene-coupled into large dimeric macrocycles using the zirconocene reagent Cp(2)Zr(py)(Me(3)SiC triple bond CSiMe(3)).
Supporting multi-device enabled Web services: challenges and open problems (2002)

Service providers face a number of challenges when providing services to users accessing the World Wide Web from hand-held devices. Among these challenges are the small display sixes, the low bandwidth, input limitations and the mobility of these devices. Web service providers need to be aware of these limitations in order to meet the exact needs of mobile clients. In this paper, we claim that new methodologies and development tools are needed in order to support the development and management of multi-device-enabled Web services. We discuss challenges and open problems faced by Web developers in adapting services to support mobile access. We share experiences we gained in extending the annual Vienna International Festival Web site to provide WAP services.
Detection of genetic changes in Barrett's adenocarcirioma and Barrett's esophagus by DNA in situ hybridization and immunohistochemistry (1994)

We have investigated the occurrence of chromosomal DNA and cell cycle-related protein changes in Barrett's epithelium and adenocarcinoma. The presence of numerical chromosomal aberrations was studied by applying nonisotopic in situ hybridization (ISH) with (peri-)centromeric DNA probes, specific for chromosomes 7, 8, 17, and Y, to routinely processed tissue sections of five cases (4 male, 1 female) of Barrett's adenocarcinoma and adjacent Barrett's epithelium. Cell cycle-related protein expression was studied by immunohistochemistry (IHC) for p53 protein and the Ki-67 antigen (Mib-1) in subsequent sections. P53 protein overexpression was found in 3 of the 5 tumors. Overrepresentation of chromosome 8 and loss of chromosome 17 were found in 2 adenocarcinomas, both also negative for p53 protein overexpression. Y-loss, mostly clonal, was detected in 3 of the 4 male adenocarcinomas and 2 cases of adjacent Barrett's epithelium. One tumor had both areas of overrepresentation and loss of the Y chromosome. All Barrett's adenocarcinomas appeared to contain aneuploid cell populations. No relation was found between cell proliferation characteristics and chromosomal aberrations. We conclude that ISH with chromosome specific DNA probes can be applied for the assessment of potentially important numerical chromosome changes in Barrett's esophagus. Further, the combination of IHC and ISH is useful for evaluation of specific genetic events.
Product configuration method based on ontology mapping (2013)

Customer requirement has the characteristics of vagueness, incompleteness and time -varying. An ontology model of product family case and customer fuzzy requirement was constructed by using sharing and reusability of ontology on semantic layer. The fuzziness of customer requirement was expressed by introducing the fuzzy ontology of linguistic variables; The incompleteness of customer requirement was solved by introducing the rules of ontology and constructing ontology rule base; The time -varying of customer requirement was solved by normalizing parameter of customer requirement and product family. It used multi -strategy ontology mapping method to achieve matching between customer requirement ontology and product family case ontology to realize product configuration based on customer requirement. Finally, the computer product configuration is taken as an example to verify the feasibility of this approach.
