Smart Identification of Overlapping Strip Pairs/Regions for Optimized LiDAR System Calibration (2013)

Recently, laser scanning systems, onboard airborne and terrestrial mobile mapping systems, have been established as a leading technology for collecting high density 3D information from an object's surface. The availability of generated surface models is very important for various industrial, military, environmental, and public applications. The accuracy of the derived point cloud coordinates from a LiDAR system is affected by inherent systematic and random errors. The impact of random errors depends on the precision of the system’s measurements, which comprise position and orientation information from the GPS/INS unit, mirror angles, and ranges. On the other hand, systematic errors are mainly caused by biases in the mounting parameters (i.e., lever arm offset and boresight angles) relating the system components as well as biases in the system measurements (e.g., ranges and mirror angles). In order to ensure the geometric quality of the collected point cloud, the LiDAR systems should undergo a rigorous calibration procedure to estimate the system parameters that minimize the discrepancies between conjugate surface elements in overlapping LiDAR strips. The main objective of this paper is to look into an existing LiDAR system calibration technique, which is based on manual selection of overlapping regions between LiDAR strips and how to increase the efficiency of this technique by automatic selection of appropriate overlapping strip pairs, which should achieve the minimum optimal flight configuration that maximizes the impact of the discrepancies among conjugate surface elements in overlapping strips as well as automatic selection of regions within the appropriate overlapping strip pairs. The methodology of the proposed technique can be summarized as follows: first, the LiDAR strip pairs are grouped based on the flight configuration; second, appropriate overlapping strip pairs from each group is automatically selected; third, regions within the appropriate overlapping strip pairs are automatically selected based on their angles (slopes and aspects) and distribution; finally, the calibration procedure is applied. The experimental results have shown that the quality of the estimated parameters using the automatic selection are quite comparable to the estimated parameters using the manual selection while the proposed method is fully automated, and much faster.
Genetic characterization of the Wyeomyia group of orthobunyaviruses and their phylogenetic relationships (2012)

Phylogenetic analyses can give new insights into the evolutionary history of viruses, especially of viruses with segmented genomes. However, sequence information for many viral families or genera is still limited and phylogenies based on single or short genome fragments can be misleading. We report the first genetic analysis of all three genome segments of Wyeomyia group viruses Wyeomyia, Taiassui, Macaua, Sororoca, Anhembi and Cachoeira Porteira (BeAr328208) in the genus Orthobunyavirus of the family Bunyaviridae. In addition, Tucunduba and Iaco viruses were identified as members of the Wyeomyia group. Features of Wyeomyia group members that distinguish them from other viruses in the Bunyamwera serogroup and from other orthobunyaviruses, including truncated NSs sequences that may not counteract the host's interferon response, were characterized. Our findings also suggest genome reassortment within the Wyeomyia group, identifying Macaua and Tucunduba viruses as M-segment reassortants that, in the case of Tucunduba virus, may have altered pathogenicity, stressing the need for whole-genome sequence information to facilitate characterization of orthobunyaviruses and their phylogenetic relationships.
Effects of a Lowered RHIC Injection Momentum (1999)

During the RHIC commissioning run with gold ions the injection kickers were about 15% too weak. One way to increase the effective kick strength is to lower the injection momentum. In this note the effects of a lower injection momentum are investigated. We consider the AGS extraction performance, the transverse matching, the beam size, the longitudinal matching, nonlinear magnetic field errors and the dynamic aperture, persistent currents, intrabeam scattering, and the power supply regulation. We study cases with injection momenta lowered by up to 30% compared to the nominal value reported in the design manual.

Liquid metal droplet solves maze (2019)

A room temperature liquid metal features a melting point around room temperature. We use liquid metal gallium due to its non-toxicity. A physical maze is a connected set of Euclidean domains separated by impassable walls. We demonstrate that a maze filled with sodium hydroxide solution is solved by a gallium droplet when direct current is applied between start and destination loci. During the maze solving the droplet stays compact due to its large surface tension, navigates along lines of the highest electrical current density due its high electrical conductivity, and goes around corners of the maze's corridors due to its high conformability. The droplet maze solver has a long life-time due to the negligible vapour tension of liquid gallium and its corrosion resistance and its operation enables computational schemes based on liquid state devices.
Performance of SR Lithography in Giga-bit DRAM Fabrication. (1996)

We have studied the characteristics of replicated resist pattern by synchrotron radiation (SR) lithography on the real topographic substrates such as a dynamic random access memory (DRAM) structure. Two type topographic structures; the step height between memory cell area and peripheral circuit area, which is regarded as the deviation of the mask/wafer gap and causes the difference of the optical image at each area, and small topographic structure in the memory cell area where the resist thickness changes continuously. It was found that the critical dimension (CD) was controlled within ±10% CD at the range of the proximity gap 14μm and a high contrast resist is effective to control the CD deviation in the memory cell area. On the real DRAM topographic structure at the height of 500Å, we obtained the CD deviation of 0.014μm(3σ) for 0.14μm transfer gate pattern. These results show SR lithography is the promising technique for giga bit scale device fabrication.
Distinctly Different Dynamics and Kinetics of Two Steroid Receptors at the Same Response Elements in Living Cells (2014)

Closely related transcription factors (TFs) can bind to the same response elements (REs) with similar affinities and activate transcription. However, it is unknown whether transcription is similarly orchestrated by different TFs bound at the same RE. Here we have compared the recovery half time (t1/2), binding site occupancy and the resulting temporal changes in transcription upon binding of two closely related steroid receptors, the androgen and glucocorticoid receptors (AR and GR), to their common hormone REs (HREs). We show that there are significant differences at all of these levels between AR and GR at the MMTV HRE when activated by their ligands. These data show that two TFs bound at the same RE can have significantly different modes of action that can affect their responses to environmental cues.

Adaptive and active materials: Selected papers from the ASME 2010 Conference on Smart Materials, Adaptive Structures and Intelligent Systems (SMASIS 10) (Philadelphia, PA, USA, 28 September–1 October 2010) (2011)

The third annual meeting of the AMSE/AIAA Smart Materials, Adaptive Structures and Intelligent Systems Conference (SMASIS) took place in the heart of historic Philadelphia's cultural district, and included a pioneer banquet in the National Constitutional Center. The applications emphasis of the 2010 conference was reflected in keynote talks by Dr Alan Taub, vice president of General Motors global research and development, 'Smart materials in the automotive industry'; Dr Charles R Farrar, engineering institute leader at Los Alamos National Laboratory, 'Future directions for structural health monitoring of civil engineering infrastructure'; and Professor Christopher S Lynch of the University of California Los Angeles, 'Ferroelectric materials and their applications'. The SMASIS conference was divided into six technical symposia each of which included basic research, applied technological design and development, and industrial and governmental integrated system and application demonstrations. The six symposia were: * SYMP 1 Multifunctional Materials; * SYMP 2 Active Materials, Mechanics and Behavior; * SYMP 3 Modeling, Simulation and Control; * SYMP 4 Enabling Technologies and Integrated System Design; * SYMP 5 Structural Health Monitoring/NDE; and * SYMP 6 Bio-inspired Smart Materials and Structures. In addition, the conference introduced a new student and young professional development symposium. Authors of papers in the materials areas (symposia 1, 2 and 6) were invited to write a full journal article on their presentation topic for publication in this special issue of Smart Materials and Structures . This set of papers demonstrates the exceptional quality and originality of the conference presentations. We are appreciative of their efforts in producing this collection of highly relevant articles on smart materials.
Anandamide transport inhibition by <scp>ARN</scp>272 attenuates nausea‐induced behaviour in rats, and vomiting in shrews (<i><scp>S</scp>uncus murinus</i>) (2013)

These results suggest that anandamide transport inhibition by the compound ARN272 tonically activates CB1 receptors and as such produces a type of indirect agonism to regulate toxin-induced nausea and vomiting. The results also provide behavioural evidence in support of a facilitated transport mechanism used in the cellular reuptake of anandamide.
Diversity of Dissimilatory Sulfite Reductase Genes ( <i>dsrAB</i> ) in a Salt Marsh Impacted by Long-Term Acid Mine Drainage (2010)

Sulfate-reducing bacteria (SRB) play a major role in the coupled biogeochemical cycling of sulfur and chalcophilic metal(loid)s. By implication, they can exert a strong influence on the speciation and mobility of multiple metal(loid) contaminants. In this study, we combined DsrAB gene sequencing and sulfur isotopic profiling to identify the phylogeny and distribution of SRB and to assess their metabolic activity in salt marsh sediments exposed to acid mine drainage (AMD) for over 100 years. Recovered dsrAB sequences from three sites sampled along an AMD flow path indicated the dominance of a single Desulfovibrio species. Other major sequence clades were related most closely to Desulfosarcina, Desulfococcus, Desulfobulbus, and Desulfosporosinus species. The presence of metal sulfides with low delta(34)S values relative to delta(34)S values of pore water sulfate showed that sediment SRB populations were actively reducing sulfate under ambient conditions (pH of approximately 2), although possibly within less acidic microenvironments. Interestingly, delta(34)S values for pore water sulfate were lower than those for sulfate delivered during tidal inundation of marsh sediments. 16S rRNA gene sequence data from sediments and sulfur isotope data confirmed that sulfur-oxidizing bacteria drove the reoxidation of biogenic sulfide coupled to oxygen or nitrate reduction over a timescale of hours. Collectively, these findings imply a highly dynamic microbially mediated cycling of sulfate and sulfide, and thus the speciation and mobility of chalcophilic contaminant metal(loid)s, in AMD-impacted marsh sediments.
Abstract A36: Interaction of the MYC oncoprotein with the tumor suppressive SWI/SNF complex member INI1 (2015)

Abstract The MYC oncogene is a key driver of cellular transformation that is deregulated in more than half of all human cancers. The transcriptional regulatory function of MYC and the wide spectrum of biological processes it mediates are critically tied to its chromatin interactors and epigenetic context. MYC is linked to chromatin remodeling through its interaction with INI1 (SMARCB1/hSNF5/BAF47), a core member of the SWI/SNF complex and a potent tumour suppressor. Recent sequencing efforts in many cancer types also identified frequent mutations in other members of this complex. However, the mechanistic understanding of the SWI/SNF complex in contributing to oncogenesis and its functional and molecular interaction with MYC remain unclear. Herein, we provide a comprehensive characterization of the MYC-INI1 interaction. We demonstrate their direct interaction and extensively delineate their minimal regions of interaction, corresponding to functionally important regions of MYC (leucine zipper) and INI1 (Repeats I and II). Genome-wide analysis reveals that INI1 and other SWI/SNF complex members share significant portions of MYC DNA-binding regions and target genes. Network analysis demonstrates MYC interaction with the SWI/SNF complex and an extended network of shared interactors belonging to additional chromatin regulatory complexes. Collectively, our findings provide significant insight into the interaction of MYC and INI1 at the level of protein-protein and protein-chromatin interactions. Citation Format: William B.

Preliminary Study of Wide Base-of-Support Footwear in Preventing Falls Caused by Lateral Slip during Walking (2012)

The present preliminary study examined whether an increase in the lateral width of footwear (base-of-support width) can reduce the risk of falling caused by induced lateral slip while turning on slippery surfaces. Wide base-of-support (BOS) footwear was designed and manufactured, with lateral widening achieved by fixing a BOS extension, using a planar linkage of 70-mm width on the lateral side of normal BOS footwear. Gait trials were conducted on 16 young healthy male adults. Subjects were instructed to walk in a straight line and to turn 60° to the right on a stainless steel floor covered with glycerol solution. As compared with the normal BOS footwear, the wide BOS footwear reduced the frequency of trials in which fall occurred due to lateral slip by up to 67% and the slip distance and slip velocity of the supporting foot were reduced by up to 40% and 35%, respectively. The results demonstrated the efficacy of increased lateral BOS width in reducing the risk of fall caused by induced lateral slip.
Surgical Images and Surgical Robots (2004)

Realization of new surgical treatment in the 21st century, it is necessary to use various advanced technologies; surgical robots, three-dimensional (3-D) medical images, computer graphics, computer simulation technology and others. Three-dimensional medical image for surgical operation provides surgeons with advanced vision. A surgical robot provides surgeons with advanced hand, but it is not a machine to do the same action of a surgeon using scissors or scalpels. Recently, as an advanced vision. "Integral Videography (IV)" which can project full color 3-D video image in real 3-D space is developed in Japan. The advanced vision and hands available to surgeons are creating new surgical fields, which are minimally invasive surgery, non-invasive surgery, virtual reality microsurgery, telesurgery, fetus surgery. neuro-informatics surgery and others in the 21st century.
Models of Amyotrophic Lateral Sclerosis (2002)

Amyotrophic lateral sclerosis (ALS) is a progressive neurological disorder caused by degeneration of the motor neurons in cortex, brainstem and spinal cord. Two experimental models of ALS are described in this unit: organotypic cultures of spinal cord, and transgenic mice expressing a human mutant superoxide dismutase 1 (SOD1) gene. Appropriate animal and cell culture models of ALS can be used to help unravel the sequence of events in motor neuronal degeneration and test potential therapies.
On the spectral theory for first-order systems without the unique continuation property (2019)

We consider the differential equation Ju′+qu=wf on the real interval (a,b) when J is a constant, invertible skew-Hermitian matrix and q and w are matrices whose entries are distributions of order zero with q Hermitian and w non-negative. In this situation, it may happen that there is no existence and uniqueness theorem for balanced solutions of a given initial value problem. We describe the set of solutions the equation does have and establish that the adjoint of the minimal operator is still the maximal operator, even though unique continuation of balanced solutions fails.
Variation-Aware Small Delay Fault Diagnosis on Compressed Test Responses (2019)

With today's tight timing margins, increasing manufacturing variations, and new defect behaviors in FinFETs, effective yield learning requires detailed information on the population of small delay defects in fabricated chips. Small delay fault diagnosis for yield learning faces two main challenges: (1) production test responses are usually highly compressed reducing the amount of available failure data, and (2) failure signatures not only depend on the actual defect but also on omnipresent and unknown delay variations. This work presents the very first diagnosis algorithm specifically designed to diagnose timing issues on compressed test responses and under process variations. An innovative combination of variation-invariant structural analysis, GPU-accelerated time-simulation, and variation-tolerant syndrome matching for compressed test responses allows the proposed algorithm to cope with both challenges. Experiments on large benchmark circuits clearly demonstrate the scalability and superior accuracy of the new diagnosis approach.
Root-Zone Soil Moisture Retrieval from CYGNSS Over-Land Observations via Bistatic Vegetation Scattering model and Hybrid Global and Local Optimization Scheme (2021)

Over the past years applications of signals-of-opportunity (SoOP) for monitoring local and global environmental parameters have been widely investigated. In particular, recent studies have shown that Global Navigation Satellite System Reflectometry (GNSS-R) can be utilized for soil moisture retrieval. This paper proposes a method for retrieving surface-to-root-zone profiles of soil moisture (RZSM) from the Cyclone Global Navigation Satellite System (CYGNSS) over-land observations, which are in the form of delay-Doppler maps (DDMs) [1] .
A multi-purpose Scart interface to support 100 Hz/16:9/multi-media displays (1994)

A new single chip digital scart interface has been designed to support all the features of digital high end TV receivers. The IC contains the entire circuitry to interface analog YUV/RGB/fast blank signals to a digital YUV system. In particular, it enables inclusion of analog RGB component signals from an external video source in parallel to the primary video signal. The fast blank signal is used to control a soft mixer between the digitized RGB (4:4:4) and an external digital YUV (4:2:2) source. Suitable applications include sample rate conversion, 16:9 display format, and 100 Hz “flicker free” display.
SOLUBLE P-SELECTIN MODERATES COMPLEMENT DEPENDENT INJURY (2000)

P-selectin is an adhesion molecule expressed on activated endothelial and platelet membranes containing 9 short consensus repeats (SCRs) similar to the composition of complement regulatory proteins. In our murine model of intestinal ischemia and reperfusion where local injury is mediated by the classical complement pathway we hypothesized the SCRs would moderate the complement response. Confirmatory data were sought following hindlimb ischemia and reperfusion where injury is both complement- and neutrophil-mediated. Mice deficient in P-selectin (P-/-) were found to have similar intestinal and hindlimb permeability compared to normal wild types mice (P+/+). When reconstituted with P+/+ platelets, but not P-/- platelets, P-/- mice subjected to intestinal ischemia had a significant 29% decrease in permeability (P < 0.05) and after hindlimb ischemia the decrease was 33% (P<0.05). Reperfusion after intestinal ischemia led to a 76% fall in CH50 in P-/- compared to sham animals (P < 0.05) indicating complement activation and consumption, but only a 36% fall in animals reconstituted with P+/+ platelets (P < 0.05). Full-length, soluble P-selectin (sPsel) derived from processed platelets, but not the truncated version of sPsel has been shown to adhere to a heat labile fraction of serum and sensitized red blood cells thereby reducing Clq adherence to the sensitized red cell. From these data we conclude that sPsel moderates complement activation by competing with C1q binding to antibody, thereby limiting activation of the classical pathway that mediates murine reperfusion injury.
Synthesis, structure, electrical and magnetic properties of the new non-stoichiometric perovskite phase, Ca2MnNbOγ (1998)

The new phase Ca 2 MnNbO γ has an orthorhombic, GdFeO 3 structure with B site disorder of Mn and Nb. The oxygen content γ varies from 5.86 to 6.00 depending on heat treatment conditions. Treatment in high pressure O 2 required for full oxidation. Magnetic susceptibility measurements indicate mixed valence (2+, 3+) of Mn for γ=5.87 and Curie-Weiss paramagnetism at high temperatures. SQUID measurements indicate spin glass-like behaviour below 15 K. Ac impedance shows semiconducting behaviour, E=0.31(2) eV. On heating in O 2 -poor atmospheres, resistive surface layers and grain boundary effects are seen, which point to a p-type conduction mechanism.
Optical Properties of Cubic CdS (2002)

We have fabricated cubic CdS films on GaAs substrates by means of a low-pressure metalorganic vapor deposition technique and studied their optical properties. The light-hole and heavy-hole exciton splitting due to the biaxial compressive strains in CdS films has been clearly observed in the photoreflectance spectrum. The temperature dependence of the free exciton energy has been determined for cubic CdS films on GaAs substrates.
