Electrical transport properties of LaNi<sub>1−<i>x</i></sub>M<sub><i>x</i></sub>O<sub>3</sub>(M = Co, Mn) thin films fabricated by pulsed laser deposition (2005)

Highly oriented thin films of LaNi1−xMxO3 (M = Mn, Co) are grown on LaAlO3(100) substrate by pulsed laser deposition. They undergo a metal to insulator transition when the Mn or Co concentration is increased. The observed conduction pattern is highly sensitive to the doping concentration in these thin films. The conduction pattern also varies as the doping element is varied from Mn to Co. There is a large dominance of electron–lattice interactions in the conduction mechanism of the charge carriers. While the metallic thin films of LaNi1−xCoxO3 show a linear variation of resistivity with temperature, LaNi1−xMnxO3 thin films exhibit a prominent square-root dependence of resistivity on temperature. At high concentrations of Mn or Co, the conduction takes place via a polaron hopping mechanism, which suggests that lattice polarization may be present in these films. The change observed in the transport properties is attributed to the charge disproportionation between the Ni3+–Ni2+ pairs, which are favoured more in Mn doped thin films. The photoelectron spectroscopic studies give evidence of charge disproportionation present in these films.
Dynamic Models of Piled Foundations (2013)

The vibration behavior of piled foundations is an important consideration in fields such as earthquake engineering, construction, machine-foundation design, offshore structures, nuclear energy, and road and rail development. This paper presents a review of the past 40 years' literature on modeling the frequency-dependent behavior of pile foundations. Beginning with the earliest model of a single pile, adapted from those for embedded footings, it charts the development of the four pile-modeling techniques: the “dynamic Winkler-foundation” approach that uses springs to represent the effect of the soil; elastic-continuum-type formulations involving the analytical solutions for displacements due to a subsurface disk, cylinder, or other element; boundary element methods; and dynamic finite-element formulations with special nonreflecting boundaries. The modeling of pile groups involves accounting for pile-soil-pile interactions, and four such methods exist: interaction factors; complete pile models; the equivalent pier method; and periodic structure theory. Approaches for validating pile models are also explored.
A multi-layer bloom filter for duplicated URL detection (2010)

It is of great significance to improve the speed of data collecting and updating in a web crawler because there are a large number of web pages in Internet. A duplicated URL detection approach based on multi-layer bloom filter algorithm is proposed in this paper, which divides an entire URL into some layers and stores them in multi-layer bloom filter. The experimental result shows that the false positive of multi-layer bloom filter algorithm is significantly lower than that of classical bloom filter algorithm, while the efficiency of the former is almost the same as the later.
Multi-task single lens for automotive vision applications (2009)

The increasing trend to use vision sensors in transportation is driven both by legislation and consumer demands for higher safety and better driving experiences. Awareness of what surrounds an automotive vehicle can directly affect the safe driving and maneuvering of that vehicle. Consequently, panoramic 360° field-of-view (FoW) imaging is becoming an industry prerequisite. However, to obtain a complete view of the area around a vehicle, several sensor systems are necessary. This paper explains how panomorph optics can satisfy the needs of various vision applications with only one sensor or panomorph lens configuration. A panomorph lens is a hemispheric wide-angle anamorphic lens with enhanced resolution in a predefined zone of interest. Because panomorph lenses feature an optimal pixel-per-degree relationship, the resulting vision systems provide ideal area coverage, which in turn reduces and maximizes the processing. Here we present how panomorph technology is one of the most promising ways to integrate many automotive vision applications (processing/viewing) onto one single camera module. For example: a single panomorph sensor on the front of a vehicle could provide all the information necessary for assistance in crash avoidance, lane tracking, early warning alerts, parking aids, road sign and pedestrian detection, as well as various video monitoring views for difficult areas such as blind spots.

Fast 3D kriging interpolation using Delaunay tetrahedron with CUDA-enabled GPU (2015)

Summary Kriging interpolation algorithm is a kind of optimal linear unbiased interpolation method and applied to many fields, especially in geological field. As a kind of regional algorithm, how to choose the neighbor points is an important part of kriging algorithm. Moreover, in recent years, with the wide use of kriging interpolation technology, higher efficiency of kriging interpolation is required and traditional kriging interpolation algorithm has not been able to meet the current requirement for efficiency. For kriging is an algorithm defined in the limited space domain, it has to select the calculation area, which is completed by selecting neighbor known points as input for interpolating unknown points. But the existing kriging interpolation method could not consider neighbor points. Instead, it uses all the known points as the input. And if all the known points are used as the input, the scheme will be infeasible. Considering these problems, this paper puts forward a fast kriging interpolation algorithm based on Delaunay tetrahedron with CUDA-enabled GPU, which establishes a spatial index for 3D Delaunay tetrahedron to quickly search neighbor points. Meanwhile, based on CUDA platform, an effective parallel interpolation strategy is proposed by using powerful computing capability of GPU to improve the efficiency of interpolation.
Creating map-based storyboards for browsing tour videos (2008)

Watching a long unedited video is usually a boring experience. In this paper we examine a particular subset of videos, tour videos, in which the video is captured by walking about with a running camera with the goal of conveying the essence of some place. We present a system that makes the process of sharing and watching a long tour video easier, less boring, and more informative. To achieve this, we augment the tour video with a map-based storyboard, where the tour path is reconstructed, and coherent shots at different locations are directly visualized on the map. This allows the viewer to navigate the video in the joint location-time space. To create such a storyboard we employ an automatic pre-processing component to parse the video into coherent shots, and an authoring tool to enable the user to tie the shots with landmarks on the map. The browser-based viewing tool allows users to navigate the video in a variety of creative modes with a rich set of controls, giving each viewer a unique, personal viewing experience. Informal evaluation shows that our approach works well for tour videos compared with conventional media players.
Bone Morphogenetic Protein-15 (2000)

In developing ovarian follicles, the regulation of cell proliferation and differentiation is tightly coordinated. Precisely how this coordination is achieved is unknown, but recent observations have suggested that molecules emitted by the oocyte are involved in the process. The newly discovered oocyte-specific growth factor, bone morphogenetic protein-15 (BMP-15), is one such molecule. At present, nothing is known about the target cells and biological functions of BMP-15. To fill this gap in our knowledge, recombinant BMP-15 and its antibody were produced and used to determine BMP-15 expression and bioactivity. BMP-15 mRNA and protein were shown to be co-expressed in oocytes throughout folliculogenesis, supporting the idea that BMP-15 is a physiological regulator of follicle cell proliferation and/or differentiation. To test this, we used primary cultures of rat granulosa cells (GCs). We found that BMP-15 is a potent stimulator of GC proliferation, and importantly, the mitogenic effect was follicle-stimulating hormone (FSH)-independent. By contrast, BMP-15 alone had no effect on steroidogenesis. However, it produced a marked decrease in FSH-induced progesterone production, but had no effect on FSH-stimulated estradiol production. This result indicates that BMP-15 is a selective modulator of FSH action. In summary, this study identifies GCs as the first target cells for BMP-15. Moreover, it identifies the stimulation of GC proliferation and the differential regulation of two crucial steroid hormones as the first biological functions of BMP-15. Significantly, BMP-15 is the first growth factor that can coordinate GC proliferation and differentiation in a way that reflects normal physiology.
Identification of small non-coding RNAs from mitochondria and chloroplasts (2006)

Small non-protein-coding RNAs (ncRNAs) have been identified in a wide spectrum of organisms ranging from bacteria to humans. In eukarya, systematic searches for ncRNAs have so far been restricted to the nuclear or cytosolic compartments of cells. Whether or not small stable non-coding RNA species also exist in cell organelles, in addition to tRNAs or ribosomal RNAs, is unknown. We have thus generated cDNA libraries from size-selected mammalian mitochondrial RNA and plant chloroplast RNA and searched for small ncRNA species in these two types of DNA-containing cell organelles. In total, we have identified 18 novel candidates for organellar ncRNAs in these two cellular compartments and confirmed expression of six of them by northern blot analysis or RNase A protection assays. Most candidate ncRNA genes map to intergenic regions of the organellar genomes. As found previously in bacteria, the presumptive ancestors of present-day chloroplasts and mitochondria, we also observed examples of antisense ncRNAs that potentially could target organelle-encoded mRNAs. The structural features of the identified ncRNAs as well as their possible cellular functions are discussed. The absence from our libraries of abundant small RNA species that are not encoded by the organellar genomes suggests that the import of RNAs into cell organelles is of very limited significance or does not occur at all.
Finite-state machine partitioning for low power (2002)

We describe an algorithm for the automatic synthesis of a network of interacting FSMs starting from a single state-table specification. The sub-machines in the decomposed FSM communicate through a set of additional interface signals. The decomposed implementation has low power dissipation because one single sub-machine is clocked at any given time and it controls the outputs values while all other sub-machines are idle. There is full cycle-by-cycle equivalence between the input-output behavior of the decomposed and undecomposed implementation.
GDF-5 can act as a context-dependent BMP-2 antagonist (2015)

Although comparison of the crystal structures of the GDF-5 R57A:BMPR-IAEC- and BMP-2:BMPR-IAEC complex revealed small ligand-specific differences, these cannot account for the different signaling characteristics because the complexes seem identical in both differently reacting cell lines. We thus predict an additional component, most likely a not yet identified GDF-5-specific co-receptor, which alters the output of the signaling complexes. Hence the presence or absence of this component then switches GDF-5's signaling capabilities to act either similar to BMP-2 or as a BMP-2 antagonist. These findings might shed new light on the role of GDF-5, e.g., in cartilage maintenance and/or limb development in that it might act as an inhibitor of signaling events initiated by other BMPs.
Adaptive frequency hopping for bluetooth robust to WLAN interference (2009)

In this letter, we propose a new adaptive frequency hopping (AFH) scheme for Bluetooth to mitigate interference from IEEE 802.11x based wireless local area network (WLAN). To fast classify available channels for the Bluetooth, we first group the Bluetooth channels according to the channel allocation of WLAN and classify groups instead of Bluetooth channels. Then, we employ a moving average technique to estimate the status of Bluetooth channels in groups more accurately. The performance of the proposed scheme is verified by computer simulation. Simulation results show that the proposed AFH scheme significantly outperforms conventional schemes.
Fault feature extracting by wavelet transform for control system fault detection and diagnosis (2002)

The paper deals with the problem of fault feature extraction from the residual in the model-based control system fault detection and diagnosis, based on the fact that the wavelet transform of a signal will maximise the modulus at its singular point in the transform domain, and the fault error has positive singularity exponent while the noise has negative singularity exponent at the corresponding singular points; the fault error and noise mixed in the residual can be separated from each other by multi-scale wavelet transform, and the modulus maximum can be taken as the fault feature, so that the fault feature becomes clearer and more recognizable and a correct decision as to whether the system fault will take place or not can be correctly made in the transform domain. This makes it easy to detect and diagnose faults in the control system.
Miscellaneous (1967)

A study was made by Miller in 1954 of children who were in utero and within 2,200 meters from the hypocenter at the time of the atomic bomb in Hiroshima. These earlier observations have with few exceptions been validated by this follow-up of the subjects at 20 years of age and the value and accuracy of clinical evaluation in early childhood is clearly indicated. The following conclusions are made. Both small head size (circumference minus 2 SD or more) and mental retardation are most closely related to (1) maternal exposure within 1,500 meters from the hypocenter, and (2) a gestational age of less than 15 weeks. The heads of infants with either small or normal circumferences at birth increase thereafter in circumference at the same rate and stop growing at the same age, thereby maintaining the same size relationships throughout childhood into adult life. Mortality in the mentally retarded group as a whole exceeds mortality in normal children. For the group of all subjects exposed within 1,500 meters the mortality rate is higher than for the subjects located beyond 1,500 meters.
Stability (over time) of modified-CS for recursive causal sparse reconstruction (2010)

In this work, we obtain sufficient conditions for the “stability” of our recently proposed algorithm, modified-CS (for noisy measurements), designed for recursive reconstruction of sparse signal sequences from noisy measurements. By “stability” we mean that the number of misses from the current support estimate and the number of extras in it remain bounded by a time-invariant value at all times. The concept is meaningful only if the bound is small compared to the current signal support size. A direct corollary is that the reconstruction errors are also bounded by a time-invariant and small value. We show that “stability” holds under mild assumptions (bounded noise, high enough SNR and large enough measurements at every time) for a simple deterministic signal model with fixed signal power and support set size; support set changes allowed at every time; and gradual coefficient magnitude increase/decrease.
Refractive index change and curvature in shock waves by angled beam refraction (1981)

Observations of front geometry and refractive index jump across shock waves in rare gases have been made with a new and particularly simple technique. The technique involves determination of the angular deflection of a narrow laser beam intersecting the shock front at a shallow angle. Measured refractive index jumps in rare gases are in excellent agreement with those calculated using Snell’s law and ideal shock theory. The apparent shock curvature is in close accord with deBoer’s theory for loading pressures below 20 Torr, but above this presure there is evidence of an indentation near tube center.

▪ Abstract The use of energy recovery provides a potentially powerful new paradigm for generation of the charged particle beams used in synchrotron radiation sources, high-energy electron cooling devices, electron-ion colliders, and other applications in photon science and nuclear and high-energy physics. Energy-recovering electron linear accelerators (called energy-recovering linacs, or ERLs) share many characteristics with ordinary linacs, as their six-dimensional beam phase space is largely determined by electron source properties. However, in common with classic storage rings, ERLs possess a high average-current-carrying capability enabled by the energy recovery process, and thus promise similar efficiencies. We discuss the concept of energy recovery and its technical challenges and describe the Jefferson Lab (JLab) Infrared Demonstration Free-Electron Laser (IR Demo FEL), originally driven by a 35–48-MeV, 5-mA superconducting radiofrequency (srf) ERL, which provided the most substantial demonstration of energy recovery to date: a beam of 250 kW average power. We present an overview of envisioned ERL applications and a development path to achieving the required performance. We use experimental data obtained at the JLab IR Demo FEL and recent experimental results from CEBAF-ER—a GeV-scale, comparatively low-current energy-recovery demonstration at JLab—to evaluate the feasibility of the new applications of high-current ERLs, as well as ERLs' limitations and ultimate performance.
Genes and Mutations Causing Autosomal Dominant Retinitis Pigmentosa (2014)

Retinitis pigmentosa (RP) has a prevalence of approximately one in 4000; 25%-30% of these cases are autosomal dominant retinitis pigmentosa (adRP). Like other forms of inherited retinal disease, adRP is exceptionally heterogeneous. Mutations in more than 25 genes are known to cause adRP, more than 1000 mutations have been reported in these genes, clinical findings are highly variable, and there is considerable overlap with other types of inherited disease. Currently, it is possible to detect disease-causing mutations in 50%-75% of adRP families in select populations. Genetic diagnosis of adRP has advantages over other forms of RP because segregation of disease in families is a useful tool for identifying and confirming potentially pathogenic variants, but there are disadvantages too. In addition to identifying the cause of disease in the remaining 25% of adRP families, a central challenge is reconciling clinical diagnosis, family history, and molecular findings in patients and families.

An application for a distributed computer architecture-realtime data processing in an autonomous mobile robot (2003)

A description is given of a data-processing structure for real-time systems with sensory feedback and a distributed computer architecture that supports it. The computer system is implemented within an autonomous mobile robot and is based on a set of independent processing modules, each of which consists of a processing core, a transport unit, and a common memory between them. Communication between modules is done in two ways. For command transportation, a direct point-to-point connection is used and transport of raw and processed sensor data is done by broadcasting. Transportation is controlled by an adjustable timetable, which is maintained by the supervisor, who slows down the driving speed and adjusts the timetable if the module does not process the given task in time. This facility allows speed of the robot to be adapted to the current processing capacity and to the complexity of the environment.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Growth, evaluation and modeling of silicon-on-ceramic solar cells (1978)

The silicon-on-ceramic (SOC) process uses inexpensive ceramic substrates to provide supported growth of silicon from the melt. The conditions for unidirectional solidification, the grain structure and other properties are quite similar to those of EFG silicon ribbon. Solar cells with interdigital electrodes have demonstrated AMl conversion efficiencies (active area) of 7.8% without AR coatings and 10.1% efficiencies with an AR coating of SiO. Mathematical modeling of the series resistance of cells shows the feasibility of making electrical contact to the base layer of the cell through slots in the substrate. However, series resistance in the base layer sets an upper limit on slot spacing for efficient cell performance.

Space-time processing for smart antennas in advanced receivers for the user terminal in 3G WCDMA systems (2003)

An adaptive multi-target space-time down-link receiver for user terminals of WCDMA systems under soft handoff is presented. The receiver consists of M antennas and K array processors, each one followed by a chip-rate equalizer and a despreader. The resulting K signals are combined in an "adaptive ratio combiner" which is updated by pilot common channel information in UTRA-FDD systems. All the structure in the FDD WCDMA downlink signal is exploited for improved performance. Simulation results for a stationary channel and for COST-259 channel models, for vehicle speed of 50 km/h, are presented.
