Feature detection in unorganized pointclouds (2019)

Feature detection in pointclouds is becoming increasingly important for a wide range of applications. For example fields of robotics, autonomous driving and medical image processing are using acquisition sensors with 3 dimensional output. These points are usually defined by x, y, and z coordinates and represents the outer surface or shell of an object. Challenges are to develop methods for effective ways to get just the relevant information in pointclouds and accelerate postprocessing steps. The approaches presented in this paper are based on innervolumetric 3D data, which are described by chaotically organized points. The data used are generated by the layer-by-layer acquisition and composition of individual point clouds in additive manufacturing. The data is merged, preprocessed and subsequently the characteristics are extracted.
KIR genotyping by reverse sequence‐specific oligonucleotide methodology (2007)

Recent studies suggest that killer cell immunoglobulin-like receptors (KIR) genotyping may be relevant to bone marrow/stem cell transplantation. The objective of this research was to develop a bead-based reverse sequence-specific oligonucleotide DNA hybridization assay for KIR genotyping using the Luminex platform. The oligonucleotide probes were designed to recognize 14 currently known KIR genes and two pseudogenes, as well as null alleles. A unique probe design was used to allow detection of two cis-polymorphic regions for typing of KIR2DS4, because the functioning alleles cannot readily be assigned by conventional probe detection systems. Assay performance was validated using DNA samples previously typed by the 13th International Histocompatibility Working Group with 100% concordant results.
Hydrogen Bonding: Regulator for Nucleophilic Fluorination (2017)

The recent advances in nucleophilic fluorination, regulated through hydrogen bonding interactions are summarized. Two main categories of fluorine nucleophiles are discussed. Alkali-metal fluorides are widely used in various fluorination transformations because they are inexpensive and safe nucleophilic fluorine sources. But the non-controllable nucleophilicity and strong basicity of some of them cause undesired side reactions, which led to the introduction of hydrogen bonding to fine tune their nucleophilicity and basicity. In contrast, an HF-based fluorine nucleophile, HF/DMPU, is in some aspects superior to the conventional HF/pyridine (Olah's reagent) or HF/Et<sub>3</sub> N because of the higher hydrogen bond basicity of DMPU. It has been used in several nucleophilic fluorinations such as fluorination of alkynes, fluoro-Prins reaction and fluorination of aziridines.

Hummocky Cross-Stratification and its Hydraulic and Climatic Implications in Talchir formation, Dudhi Nala, Hazaribagh, Bihar (1989)

Abstract Storm products are exceedingly rare in glacio-marine and -Iacustrine sequences. However, glacigenic Permo-Carboniferous Talchir sequence in Dudhi nala, West Bokaro coal basin, Bihar, registers two distinct hummocky cross-stratified facies units of considerable thickness. This, in turn, suggests the activity of storm waves vis-a-vis the removal of iceberg cover and considerable amelioration of climate during Talchir times.
Occurrence of insertion sequence (IS) regions on plasmid deoxyribonucleic acid as direct and inverted nucleotide sequence duplications (1975)

Insertion sequence (IS) regions have been identified previously as a cause of strongly polar mutations in Escherichia coli and several bacteriophages. The present experiments indicate that genetically characterized IS regions occur on bacterial plasmid deoxyribonucleic acid (DNA) as both direct and inverted DNA sequence duplications. The DNA insertion which has been shown previously (Sharp et al., 1973) to control expression of tetracycline resistance in the R6-5 plasmid, and which occurs as directly and inversely repeated DNA sequences adjacent to the region believed to contain the tetracycline resistance gene, has been identified as IS3. A second genetically characterized insertion sequence (IS1) has been identified as a direct DNA duplication occurring at both junctions of the resistance transfer factor and R-determinant components of R6-5 and related plasmids. A model is presented for the reversible dissociation of resistance transfer factor and R-determinant components of co-integrate R plasmids at the sites of DNA sequence homology provided by the repeated IS regions.
Characterization of Plasmodium falciparum and Plasmodium vivax recent exposure in an area of significantly decreased transmission intensity in Central Vietnam (2018)

Previous studies in Central Vietnam demonstrated high occurrence of asymptomatic and sub-microscopic infections. However, in this study very few asymptomatic infections were detected despite serological evidence of continued transmission. Nonetheless, the factors associated with spatial heterogeneity in transmission could be evaluated using serological classification of recent exposure, which supports the usefulness of serological methods to monitor malaria transmission.

Trends in the pattern of blindness and major ocular diseases in Singapore and Asia. (1998)

This article details the changing trends in the major causes of blindness and visual impairment in Singapore over the past four decades. A comprehensive review of existing data from published and unpublished sources on ocular disease studies and surveys in Singapore was conducted. The rates of blindness and visual impairment from cataract, age-related macular degeneration, glaucoma, diabetic retinopathy and refractive errors, as well as other major diseases are described and compared with other Asian countries. Such epidemiological data on the blinding conditions in our population are vital in the understanding of trends in ocular diseases, as well as in prioritizing current health services and preventive programmes.

Impact of spectral hole burning on initial loading scenarios in DWDM submarine cable systems (2004)

Submarine DWDM cable systems are designed for very high capacities at full loading, but initial loading could consist of few channels. We present a channel loading scheme that suppresses spectral hole burning impact in broadband systems. Such loading can be accomplished with few loading tones and allows for effective in-service upgrades.

Alteration Of Susceptibility To Edta, Polymyxin B And Gentamicin In Pseudomonas Aeruginosa By Divalent Cation Regulation Of Outer Membrane Protein H1 (1983)

Induction of outer membrane protein H1 in Pseudomonas aeruginosa results in decreased susceptibility to aminoglycosides, polymyxin B, and EDTA. We have previously shown that protein H1 can become the major cellular protein in cells grown in low (0.02 mM) Mg2+. The induction of protein H1 was prevented by supplementation of low Mg2+ medium with Mg2+, Ca2+, Mn2+, or Sr2+ (each at 0.5 mM), but not with Zn2+, Ba2+, Sn2+, Al3+ or Na+ (each at 0.5 mM). Only cells grown in the presence of those cations which failed to prevent H1 induction were resistant to the cationic antibiotics, polymyxin B and gentamicin, and to chelators of divalent cations. Cells grown in Ca2+, but not in Mg2+, were susceptible to outer membrane permeabilization by the Ca2+ specific chelator EGTA, whereas both were susceptible to EDTA. In agreement with this, cells grown in Mg2+, Ca2+, Mn2+, or Zn2+ showed enhanced levels of these cations respectively as their major cell envelope-associated cation. When cells were shifted from low to high Mg2+ medium, the time course of the decrease in the levels of protein H1 correlated well with the increase in sensitivity to EDTA and polymyxin B. These results support the hypothesis that protein H1 acts to replace divalent cations at a critical outer membrane site attacked by cationic antibiotics and chelators of divalent cations, and suggest that only a small proportion of the total divalent cation-binding sites in the outer membrane are susceptible to attack by these agents.

Topology Synthesis of Two-Phase Compliant Actuators (1999)

Abstract This paper describes how the topology optimization method can be used as a tool for the synthesis of two-phase compliant actuators. Two materials, one or both being active materials, are distributed in a design domain such that the work performed on an elastic workpiece is maximized. The two-material design is obtained by introducing two variables per element. One variable determines the relative density of material in the element and the other variable determines the material type. Examples demonstrate the design of thermal actuators and gripping mechanisms.
A New Constitutive Model for the Compressibility of Elastomers at Finite Deformations (2001)

Abstract Although traditional constitutive models for rubbery elastic materials are incompressible, many materials that demonstrate nonlinear elastic behavior are somewhat compressible. Clearly important in hydrostatic deformations, compressibility can also significantly affect the response of elastomers in applications for which several boundaries are rigidly fixed, such as bushings, or triaxial states of stress are realized. Compressibility is also important for convergence of finite element simulations in which a rubbery elastic constitutive law is in use. Volume changes that reflect compressibility have been observed historically in both uniaxial tension and hydrostatic compression tests; however, there appear to be no data obtained from both types of tests on the same material by which to validate a compressible hyperelastic law. In this paper, we propose a new compressible hyperelastic constitutive law for elastomers and other rubbery materials in which entropy and internal energy changes contribute to the volume change. Using data from the literature, we show that this law is capable of reproducing both the pressure—volume response of elastomers in hydrostatic compression, as well as the stress—stretch and volume change—stretch data of elastomers in uniaxial tension.

New Exact Spherical Flow Solution with Storage and Skin for Early-Time Interpretation with Applications to Wireline Formation and Early-Evaluation Drillstem Testing (1998)

Abstract The wireline formation tester, which is frequently operated over short durations, and a new formation testing tool that obtains pressure measurements during the drilling program, have provided the impetus to develop improved pressure transient analysis methods that support formation evaluation during early-to-intermediate test times. Existing methods, for example, apply to late times only, and are approximate in that they do not model the entire timewise pressure response; alternatively, the detailed models that are available for more exact analysis are numerical, chart-oriented, and not amenable to simple physical interpretation. This paper extends recent work that has solved the spherical flow boundary value problem for storage with an exact analytical solution.1,2 Here, the general spherical flow formulation, including both wellbore storage and skin effects, is solved by inverting the complete Laplace transform to produce an exact, closed form, analytical solution. This new solution reduces to previously published early- and late-time solutions in the respective asymptotic limits. However, the new solution permits convenient pressure response to theory matching over the complete time regime (early-, transitional-, and late-time data), rather than conventional late-time, spherical flow matching; it permits critical pressure-transient interpretation using only early-to-intermediate-time data, thereby reducing required rig time. The new solution is derived for the full initial-boundary value problem for transient, compressible, spherical flow using Laplace transforms. Closed-form expressions are obtained for pressure, pressure derivative, and sandface flow rate in terms of complex error functions. These exact solutions are compared to existing spherical solutions obtained by numerical transform inversion, and also to finite element results that include the three-dimensional effects of wellbore geometry. The accuracy and interpretation speed of the new solution permits systematic determination of all flow parameters, to include storage coefficient, skin effect, formation fluid compressibility, permeability, and pore pressure. Its application to a new type of well test tool designed for pressure testing during the drilling program is described. Synthetic data from wireline formation testers and a new drill pipe conveyed pressure test system are analyzed to illustrate the utility and power of the new solution. These examples are used to demonstrate how the new approach can improve real-time regression analysis used in determining formation properties.
The Free Form XR Photovoltaic Concentrator: a High Performance SMS3D Design (2008)

A novel photovoltaic concentrator is presented. The goal is to achieve high concentration design with high efficiency and high acceptance angle that in the same time is compact and convenient for thermal and mechanical management [1]. This photovoltaic system is based on 1 cm2 multi-junction tandem solar cells and an XR concentrator. The XR concentrator in this system is an SMS 3D design formed by one reflective (X) and one refractive (R) free-form surfaces (i.e., without rotational or linear symmetry) and has been chosen for its excellent aspect ratio and for its ability to perform near the thermodynamic limit. It is a mirror-lens device that has no shadowing elements and has square entry aperture (the whole system aperture area is used for collecting light). This large acceptance angle relaxes the manufacturing tolerances of all the optical and mechanical components of the system included the concentrator itself and is one of the keys to get a cost competitive photovoltaic generator. For the geometrical concentration of 1000x the simulation results show the acceptance angle of ±1.8 deg. The irradiance distribution on the cell is achieved with ultra-short homogenizing prism, whose size is optimised to keep the maximum values under the ones that the cell can accept. The application of the XR optics to high-concentration is being developed in a consortium leaded by The Boeing Company, which has been awarded a project by US DOE in the framework of the Solar America Initiative.

Double-Four-Ring [Si8O12][OH]8 Cyclosilicate and Functionalized Spherosilicate Synthesis from [N(n-C4H9)4]H7[Si8O20]·5.33H2O Cyclosilicate Hydrate Crystals (2017)

A new synthesis method for preparing spherosilicates with a double-four-ring (D4R) silicate core (Si8O12) and functional siloxy substituents such as (OSi(CH3)2Cl) on the vertices was discovered. Key to this achievement was the synthesis of [N(n-C4H9)4]H7[Si8O20]·5.33H2O D4R cyclosilicate hydrate precursor crystals having only 5.33 water molecules per D4R unit, which is much smaller than the number in the state-of-the-art tetramethylammonium- and choline-containing cyclosilicate hydrate crystals that have up to 65 water molecules per D4R. The low water content allows the use of bifunctional silylating agents such as dichlorodimethylsilane that lose their chloride functionality upon reaction with water molecules. Dissolution of [N(n-C4H9)4]H7[Si8O20]·5.33H2O crystals in acidified tetrahydrofuran liberates uncharged D4R [Si8O12][OH]8 cyclosilicate molecules, as shown by small angle X-ray scattering and 29Si nuclear magnetic resonance. A concentrated stable solution of [Si8O12][OSi(CH3)2Cl]8 spherosilicate compound was obtained by silylation with Cl2(CH3)2Si. It is a unique way to prepare a stable solution of this attractive spherosilicate with dimethylsilyl chloride chemical functionality suited for derivatization or hybrid material synthesis. With the change in the silylating agent, the new synthesis pathway allows the quantitative synthesis of other spherosilicates such as [Si8O12][OSi(CH3)2H]8 with high yield and purity.

Secure secondary utilization system of genomic data using quantum secure cloud (2022)

Secure storage and secondary use of individual human genome data is increasingly important for genome research and personalized medicine. Currently, it is necessary to store the whole genome sequencing information (FASTQ data), which enables detections of de novo mutations and structural variations in the analysis of hereditary diseases and cancer. Furthermore, bioinformatics tools to analyze FASTQ data are frequently updated to improve the precision and recall of detected variants. However, existing secure secondary use of data, such as multi-party computation or homomorphic encryption, can handle only a limited algorithms and usually requires huge computational resources. Here, we developed a high-performance one-stop system for large-scale genome data analysis with secure secondary use of the data by the data owner and multiple users with different levels of data access control. Our quantum secure cloud system is a distributed secure genomic data analysis system (DSGD) with a "trusted server" built on a quantum secure cloud, the information-theoretically secure Tokyo QKD Network. The trusted server will be capable of deploying and running a variety of sequencing analysis hardware, such as GPUs and FPGAs, as well as CPU-based software. We demonstrated that DSGD achieved comparable throughput with and without encryption on the trusted server Therefore, our system is ready to be installed at research institutes and hospitals that make diagnoses based on whole genome sequencing on a daily basis.
