Ground‐based network observation of Asian dust events of April 1998 in east Asia (2001)

We coordinated a ground‐based network that has been in use since 1997 to observe Asian dust during springtime. Huge Asian dust events that occurred in the middle of April 1998 were captured by this network. In this paper we present the organization of the network; a description of the instruments, including the lidar, sky radiometer, and optical particle counter; and the results of the observation, and offer discussions regarding the transport mechanism of Asian dust in east Asia using an on‐line tracer model. We discussed the time series of the surface concentration and the height distribution of the dust. A cutoff cyclone generated during the dust episode was responsible for trapping and sedimentation during the transportation of the Asian dust, particularly in the southern parts of China and Japan. Horizontal dust images derived from NOAA/AVHRR clearly revealed the structure of the vortex. The lidar network observation confirmed the general pattern of dust height distribution in this event; the height of the major dust layer was about 3 km over Japan but was higher (4 to 5 km) in Seoul and Hefei. A thin dust layer in the upper troposphere was also commonly observed in Hefei and Japan. Evidence of the coexistence of dust and cirrus was shown by the polarization lidar. The lidar network observation of Asian dust and satellite remote sensing provide key information for the study of the transport mechanism of Asian dust. Further extension of the lidar network toward the interior of the continent and the Pacific Rim would reveal the greater global mechanism of the transportation.

Transformation-based reconstruction for audio transmissions over the Internet (2002)

The paper studies the design of data transformation algorithms for audio data transmitted over the Internet, with a goal of reconstructing the original signals by the receiver with little distortions in the presence of bursty loss of packets. It assumes that a single audio stream is interleaved into multiple packets, and a lost sample at the receiver is reconstructed as the interpolation of adjacent samples received. We propose a non redundant transformation based reconstruction algorithm that can minimize the reconstruction error for any fixed, interpolation based reconstruction algorithm. Its basic idea is that the sender transforms the input audio stream optimally, based on the reconstruction method used at the receiver before sending the data packets. Consequently, the receiver is able to recover much better from losses of packets than without any knowledge of what the signals should be. In particular, we study our transformation algorithm based on one popular linear interpolation based reconstruction algorithm. We found that our scheme can improve the signal to noise ratio (SNR) by 1 to 2 dB with very little extra computation efforts as compared to the scheme without transformation.
TOWARDS ELIMINATION AND GENETIC MANIPULATION OF ERGOT ALKALOID PRODUCTION IN FUNGAL ENDOPHYTES (2009)

Clavicipitaceous fungal endophytes provide several ecological benefits to their hosts. Besides improving host’s growth characteristics, Neotyphodium coenophialum, the endophyte of tall fescue (Lolium arundinaceum), produces ergot alkaloids that have been proposed to be involved in fescue toxicosis. One approach to address the toxicosis problem is to genetically manipulate and modify N. coenophialum by knocking out a pair of homologous genes, (dmaW1 and dmaW2), encoding dimethylallyltryptophan synthase, the enzyme for the first and determinant step in ergot-alkaloid biosynthesis. In this study, disruption of dmaW2 was attempted using several disruption methods. Out of 1522 transformants screened, three putative knockouts were identified. Southern blot analysis of digested genomic DNA indicated that homologous gene replacement at dmaW2 locus took place while dmaW1 was still present. Chromosome separation followed by Southern-blot hybridization showed that the dmaW genes in N. coenophialum are located on different chromosomes. The aim of this study was to obtain a nontoxic endophyte free of marker genes that could be used to inoculate popular tall fescue cultivars. Therefore the Cre/loxP system developed in this study allows reusing the marker gene for sequential transformations. Protoplasts from Neotyphodium coenophialum, Neotyphodium uncinatum, or Epichloë festucae isolates, containing a floxed hygromycin phosphotransferase (hph) gene (loxP::hph::loxP), were transfected with a Crerecombinase expression plasmid and then cultured without selection. The marker was excised in 0.5-2% of the colonies, leaving a single loxP sequence. This strategy will help to reduce the concerns related to field release or commercialization of economically important grasses associated with manipulated fungal strains. It is expected that the technology will likely be adapted and applied in other fungal species. Manipulation of the ergot alkaloid (EA) gene cluster from C. purpurea and C. fusiformis by introducing and expressing its genes in different fungal-grass symbionts was also investigated. Heterologous expression of the ergot alkaloid cluster could result either in the synthesis of compounds similar to the ones produced by the host or in synthesis of novel compounds with new modes of action. Even though the results indicated that several EA genes were expressed in the new symbiota, none of the ergot alkaloids intermediates were detected.
Molecular cloning, nucleotide sequence and fine‐structural analysis of the <i>Corynebacterium glutamicum fda</i> gene: structural comparison of <i>C. glutamicum</i> fructose‐1,6‐biphosphate aldolase to class I and class II aldolases (1989)

The Corynebacterium glutamicum fda gene encoding fructose-1,6-biphosphate (FBP) aldolase has been isolated by complementation of an Escherichia coli mutant. The nucleotide sequence of a 3371 bp chromosomal fragment containing the C. glutamicum fda gene was determined. The N-terminal amino acid sequence of C. glutamicum FBP aldolase identified the correct initiation site for the fda gene, and a molecular weight of 37,092 was predicted for the fda polypeptide. S1 nuclease mapping identified the transcriptional start site, and Northern hybridization analysis indicated that the fda gene encodes a single 1.3 kb transcript. The primary structure of C. glutamicum FBP aldolase shows strong homology to class II FBP aldolases. Conservation of primary structure was observed between class I and class II aldolases, but several residues essential for catalytic activity in class I aldolases were absent from class II aldolases.
Ten years of predictions … and counting (2005)

The CASP experiment has been run every other year since 1994. Its objective is to subject the available structure prediction methods to a blind test. This is a short report of the highlights of its last edition. 'Men who wish to know about the world must learn about it in its particular details' (Heraclitus of Ephesus, 535-475 bc).
Electrical capacitance tomography for flow imaging: system model for development of image reconstruction algorithms and design of primary sensors (1992)

A software tool that facilitates the development of image reconstruction algorithms, and the design of optimal capacitance sensors for a capacitance-based 12-electrode tomographic flow imaging system are described. The core of this software tool is the finite element (FE) model of the sensor, which is implemented in OCCAM-2 language and run on the Inmos T800 transputers. Using the system model, the in-depth study of the capacitance sensing fields and the generation of flow model data are made possible, which assists, in a systematic approach, the design of an improved image-reconstruction algorithm. This algorithm is implemented on a network of transputers to achieve a real-time performance. It is found that the selection of the geometric parameters of a 12-electrode sensor has significant effects on the sensitivity distributions of the capacitance fields and on the linearity of the capacitance data. As a consequence, the fidelity of the reconstructed images are affected. Optimal sensor designs can, therefore, be provided, by accommodating these effects.
Wind turbine control system (2006)

U uvjetima kada vjetroelektrane postaju sve važniji cimbenici EES-a javlja se potreba za vrlo pouzdanim radom vjetroagregata. Zbog toga vjetroagregati moraju biti opremljeni sofisticiranim sustavom upravljanja koji je u stanju voditi vjetroagregat kroz vrlo razlicite pogonske uvjete određene vremenskim prilikama. U ovom su radu opisane glavne znacajke sustava upravljanja suvremenih komercijalnih vjetroagregata u klasi snage reda 1 MW. Poseban naglasak stavljen je na upravljanje brzinom vrtnje i snagom generatora. Također je istaknuta velika interakcija sustava upravljanja s konstrukcijom sustava te specificnosti projektiranja sustava vjetroagregata koje iz toga proizlaze.
Survival after Lung Volume Reduction in Chronic Obstructive Pulmonary Disease (2007)

Occlusion of the small airways by inflammatory exudates containing mucus is associated with early death in patients with severe emphysema treated by lung volume reduction surgery. Corticosteroid treatment dampens the host immune response in these airways by reducing lymphoid follicles without changing wall thickening and luminal occlusion.
Playas y paseos marítimos. El nuevo paisaje urbano de Benidorm (1956-1986) (2014)

espanolEsta comunicacion recorre la evolucion del paisaje urbano de Benidorm, como ciudad vertical (acotado entre dos fechas clave: 1956 y 1986), con la aprobacion de su PGOU, inspirado en un urbanismo funcionalista (CIAM), enfocado a un turismo de masas en aumento ano tras ano. Acontecimientos, turismo y planeamiento justificaban las diferentes ampliaciones urbanas de Benidorm, sometidas a constantes modificaciones y que se reflejaba en una libertad a traves del analisis y relacion entre el nuevo skyline vertical (de bloques y rascacielos de uso privado) y el tandem paseo maritimo-playa (de espacios urbanos de uso publico). Para este seguimiento se hace necesario conocer como se construye la propia ciudad y, en particular, sus nuevos frentes maritimos que constituyen la postal mas importante de cualquier ciudad turistica litoral –su imagen–, la que se publicita como reclamo: la fachada que se extiende tras sus playas y cuyo exito depende de la capacidad de articulacion los espacios publicos que entrelazan la trama urbana con su frontera maritima. EnglishThis communication traces the evolution of the urban landscape of Benidorm as vertical city (bounded between two key dates: 1956 and 1986), with the approval of the General Plan, inspired by a functionalist urban planning (CIAM), focused on mass tourism on the rise year after year. Events, tourism and planning justifying different Benidorm urban extensions, subject to constant change and that was reflected in a freedom through analysis and a new relationship between vertical architecture (skyscrapers blocks and private use) and the tandem boardwalk-beach (urban spaces for public use). For this follow-up is necessary to know how to build the city itself and, in particular new waterfronts that are the most important post any coastal tourist city-his image, which is advertised as a teaser: the facade which extends after its beaches and its success depends on the ability to articulate the public spaces that weave the urban fabric with its maritime border.
Ultrasonic linear motor using surface acoustic waves (1996)

The first success in the operation of an ultrasonic linear motor at HF band driving frequency using the Rayleigh wave is described. The substrate material is a 127.8/spl deg/ Y-cut LiNbO/sub 3/ wafer whose diameter is three inches. Four interdigital transducers (IDT's) are arranged to excite x- and y-propagation waves in both directions. The dimensions of the IDT are 25 mm aperture size, 400 /spl mu/m pitch, 100 /spl mu/m strip width, and 10 pairs. The operation area is about 25 mm square, The driving frequency is about 9.6 MHz in the x direction and about 9.1 MHz in the y direction. The most important point of the success is the shape of the contact surface and slider materials. For the contact materials, small balls about 1 mm in diameter are introduced to obtain sufficient contact pressure around 100 MPa. The use of ruby balls, steel balls, and tungsten carbide balls is investigated. Each slider has three balls to enable stable contact at three points. The maximum transfer speed is about 20 cm/s. The transfer speed is controllable by changing the driving voltage.
Evidence for a Stepwise Evolution of the CD3 Family (2000)

The three CD3 components of the TCR complex are encoded as clustered genes in mammals. The evolution of such a multimeric complex is likely to occur stepwise. The chicken CD3 cluster was entirely sequenced, and, in contrast to mammals, only two chicken CD3 genes were found to be physically linked to the unrelated genes HZW10 and epithelial V-like Ag flanking both sides of the CD3 cluster. Biochemical analyses of CD3 immunoprecipitates confirmed the presence of only two CD3 proteins and revealed an essential role for CD3gammadelta glycosylation during assembly. Functional analyses indicated that the chicken TCR/CD3 complex was efficiently down-regulated by phorbol ester treatment, demonstrating the integrity of a CD3gamma-like cytoplasmic internalization motif. These data argue for a stepwise CD3 evolution, with major differences in the TCR/CD3 structure between mammalian and nonmammalian vertebrates setting a basis for the understanding of the CD3 phylogeny and proving the ancestral nature of the CD3gammadelta protein.
Analysis of Commutated Networks Employing Feedback Circuits (1969)

A method of analysis has been developed for feedback systems employing commutated networks in the forward loop and linear transfer functions in the feedback loop. The method handles single-phase and polyphase commutated networks as well as coupled and uncoupled networks. Although commutated networks are linear from the superposition theory viewpoint, linear feedback theory is shown to be not applicable because of the harmonics present in the feedback loop. Techniques for simplifying the analysis of commutated networks by the use of equivalent block diagrams provide additional insights into commutated network operation.
Exploring the design of an intentional naming scheme with an automatic constraint analyzer (2000)

Lightweight formal modeling and automatic analysis were used to explore the design of the intentional naming system (INS), a new scheme for resource discovery in a dynamic networked environment. We constructed a model of INS in Alloy a lightweight relational notation, and analyzed it with the Alloy Constraint Analyzer, a fully automatic simulation and checking tool. In doing so, we exposed several serious flaws in both the algorithm of INS and the underlying naming semantics. We were able to characterize the conditions under which the existing INS scheme works correctly, and evaluate proposed fixes.
Polarization Diversity Tripole Adaptive Array with Minimum Bit Error Rate Approach (2006)

A polarization diversity adaptive antenna array using a tripole array is presented in this paper. Tripole array constitutes three mutually perpendicular dipoles all with their centers at the same location. This antenna adapts to desired user polarization as well as angle of arrival. It minimizes bit error rate (BER) better through polarization diversity when desired user and other interfering users arrive from the same direction or are very close to the desired user direction but with different polarizations. Simulation results show that the array, with minimum bit error rate approach, provides significant performance gain in terms of smaller BER over standard minimum mean square error (MMSE) approach. This array can be used for polarization diversity along with spatial diversity
GaN‐on‐silicon high electron mobility transistors with blocking voltage of 3 kV (2015)

A three‐terminal breakdown voltage over 3 kV is reported on AlGaN/GaN high‐electron‐mobility transistors (HEMTs) grown on silicon (Si) (111) substrate with a buffer thickness of 5.5 µm. The breakdown voltage of the 1.5 × 50 μm 2 devices has been improved by more than 200% by applying a local substrate removal all around the drain of the transistors in order to suppress the parasitic substrate conduction phenomenon. This establishes a new record breakdown voltage for GaN‐on‐silicon lateral power devices while maintaining a low specific on‐resistance of about 10 mΩ · cm 2 .

Phylogeography of Asian wild rice, <i>Oryza rufipogon</i> , reveals multiple independent domestications of cultivated rice, <i>Oryza sativa</i> (2006)

Cultivated rice, Oryza sativa L., represents the world's most important staple food crop, feeding more than half of the human population. Despite this essential role in world agriculture, the history of cultivated rice's domestication from its wild ancestor, Oryza rufipogon, remains unclear. In this study, DNA sequence variation in three gene regions is examined in a phylogeographic approach to investigate the domestication of cultivated rice. Results indicate that India and Indochina may represent the ancestral center of diversity for O. rufipogon. Additionally, the data suggest that cultivated rice was domesticated at least twice from different O. rufipogon populations and that the products of these two independent domestication events are the two major rice varieties, Oryza sativa indica and Oryza sativa japonica. Based on this geographical analysis, O. sativa indica was domesticated within a region south of the Himalaya mountain range, likely eastern India, Myanmar, and Thailand, whereas O. sativa japonica was domesticated from wild rice in southern China.
