IR Spectrum of the H<sub>5</sub>O<sub>2</sub><sup>+</sup> Cation in the Context of Proton Disolvates L−H<sup>+</sup>−L (2006)

The H(5)O(2)(+) ion has been studied in chlorocarbon, benzene, and weakly coordinating anion environments to bridge the gap between the gas-phase and traditional condensed-phase investigations. Symmetrical cations of the type [H(5)O(2)(+) x 4Solv] are formed via H-bonding with the terminal O-H groups. In the infrared spectrum, the nu(s)OH and nu(as)OH vibrations behave in a manner similar to those of common water molecules: the stronger is the H-bonding interaction with the surroundings, the lower is the frequency shift. A consistent pattern of IR bands from the central O-H(+)-O group is identified, regardless of the strength of the interaction of H(5)O(2)(+) with its environment. Three intense bands develop: a (860-995 cm-1), b (1045-1101 cm(-1)), and c (1672-1700 cm(-1)), as well as two weak bands, d ( approximately 1300 cm(-1)) and e ( approximately 1400-1500 cm(-1)). These fingerprint bands are highly characteristic for vibrations of O-H-O group irrespective of formal charge. They are seen in symmetrical proton disolvates of the type L-H(+)-L, where L is an O-atom donor (alcohol, ether, ketone, phosphate, etc.), and in [A-H-A](-) acid salts (A(-) = oxyanion). The commonality is equivalency of the two O-atoms, a short O...O distance (ca. 2.40 Angstrom), and a flat-bottomed potential well for the bridging proton, that is, a short, strong, low-barrier H-bond. Assignments for bands a-e are suggested in an attempt to resolve inconsistencies between experimental and calculated data.

Elongases Synthesizing Very Long Chain Monounsaturated Fatty Acids in Developing Oilseeds and Their Solubilization (1989)

Particulate (15,000 x g ) fractions from developing seeds of mustard (Sinapis alba), honesty (Lunaria annua), and nasturtium (Tropaeolum majus) synthesize radioactive very long chain (n9)-(Z)-monounsaturated fatty acids, e.g. gadoleic (20:1). erucic (22:1). and nervonic (24:1) acids from [1- 14 C ]oleoyl-CoA with malonyl-CoA or from [2- 14 C]m alonyl-CoA with oleoyl-CoA . Pyridine nucleotides are required for the elongation reactions. Both NADH and NADPH are equally effective for the formation of 20:1, but NADPH is the preferred reductant for the formation of 22:1, which suggest the existence of separate elongase systems. Detergents, such as Triton X-100 and octyl thioglucoside, stimulate the elongation at low concentrations, but they are inhibitory at high concentrations. Partial solubilization of the elongase system using these detergents has been achieved.
A method for measuring the solid particle permittivity or electrical conductivity of rocks, sediments, and granular materials (2003)

Measurement of the effective dielectric permittivity of porous media provides an elegant method of estimating both the porosity and water content of soils, sediments, and rocks. Obtaining accurate estimates of water content can only be achieved if the models relating the measured permittivity to water content work well. One of the difficulties with testing physical models describing two‐ and three‐phase dielectric mixtures (saturated and unsaturated systems) is obtaining an accurate value for the permittivity of the mineral matrix. No direct measurement method has been presented for rocks and soils, so the solid permittivity value is often an estimate of 5, essentially remaining a fitting parameter. We present a measurement method requiring no preassumed theoretical model. The method requires the measurement of the effective permittivity of a granular material immersed in fluids of differing permittivity and interpolation between the range of data points. Measurements of the permittivity of the mineral matrix of a number of materials are presented, including glass beads (7.6), quartz sand (4.7), calcareous seashell fragments (8.9), hematite ore (18.1), tuff (6.0), and a sandy loam soil (5.1). Estimates based on using mixing models to obtain the solid permittivity are demonstrated to underestimate the permittivity of hematite ore by between 0% and 45%, depending on the model and packing. The method is also suitable for measuring the electrical conductivity of granular minerals by changing the electrical conductivity of the bathing solution. Results for the electrical conductivity of hematite ore (0.040 dS m −1 ) and carborundum (10.9 dS m −1 ) are presented.
Retrofitting the Partially Privileged Mode for TEE Communication Channel Protection (2018)

ARM TrustZone provides a Trusted Execution Environment (TEE) to isolate security-critical services, which are generally invoked from the Rich Execution Environment (REE) through a communication channel established by executing the Secure Monitor Call (SMC) with the general registers configured as input parameters. Unfortunately, the communication channel has been abused by adversaries to incur misbehavior of the TEE, to analyze the internal working of the TEE, and to exploit its vulnerabilities. We therefore propose the TEE defense (TFence) framework that enables the creation of a partially privileged (par-priv) process, which benefits from the coordination of the system mode and virtualization extension. More specifically, on ARM architecture, direct invocation of hypercall and SMC is not allowed in the user process; however, we limitedly escalate the privilege of the process to enable it to directly communicate with trust anchors such as hypervisor and TrustZone. This approach enabled us to remove the kernel dependency when the process communicates with the TEE, which also reduces the attack surface to the critical part of the application involved in the communication. Besides, direct communication with the hypervisor facilitates the adoption of application-shielding approaches to protect the critical part and to restrict arbitrary access to the TEE.

Review on the Methods of Automatic Liver Segmentation from Abdominal Images (2014)

Automatic liver segmentation from abdominal images is challenging on the aspects of segmentation accuracy, automation and robustness. There exist many methods of liver segmentation and ways of categorisingthem. In this paper, we present a new way of summarizing the latest achievements in automatic liver segmentation. We categorise a segmentation method according to the image feature it works on, therefore better summarising the performance of each category and leading to finding an optimal solution for a particular segmentation task. All the methods of liver segmentation are categorized into three main classes including gray level based method, structure based method and texture based method. In each class, the latest advance is reviewed with summary comments on the advantages and drawbacks of each discussed approach. Performance comparisons among the classes are given along with the remarks on the problems existed and possible solutions. In conclusion, we point out that liver segmentation is still an open issue and the tendency is that multiple methods will be employed together to achieve better segmentation performance.
Biefeld-Brown Effect: Misinterpretation of Corona Wind Phenomena (2004)

With its theoretical origins dating back to the early 1920s, the Biefeld‐Brown effect was believed to be responsible for the generation of thrust in capacitor configurations exposed to high voltage. This thrust was claimed to be unrelated to corona wind phenomena and to exist in vacuum. These claims, although only published in patents, survived until recent publications for very advanced propulsion concepts. Brown’s and similar work, as well as credible theoretical and experimental studies relating to the Biefeld‐Brown effect, are reviewed. Moreover, an experiment was carried out to investigate any thrust not related to corona discharges. No thrust was detected within the accuracy of the experimental setup. This puts new boundaries on any anomalous Biefeld‐Brown force. Measurements indicate that such anomalous force must be at least five orders of magnitude below corona wind phenomena and must have at least a two orders of magnitude higher power-to-thrust ratio compared to traditional electric propulsion thrusters. Hence, even if the effect exists, it would not be attractive for space propulsion. The obtained results suggest that corona wind effects were misinterpreted as a connection between gravity and electromagnetism.
Direct Waveguide Writing with High Energy High Repetition Rate Picosecond Laser Pulses (2012)

Abstract Direct femtosecond pulse laser waveguide writing based on laser induced localized modification of the refractive index of bulk glass can be a versatile fabrication method for many micro applications. Although the method's potentials have been realized its application is still rather limited, either due to the slow writing speeds caused by low laser pulse repetition rates of amplified systems or due to the shallow structuring depths restricted by low pulse energies of nonamplified lasers. In this work we investigate the direct waveguide writing process using a picosecond laser that allows fast and deep waveguide writing due to high pulse energies available at high pulse repetition frequencies.
Modeling and simulating crowdsourcing as a complex biological system : human crowds manifesting collective intelligence on the internet (2011)

Crowdsourcing, a real-life instance of human collective intelligence, is a phenomenon that changes the way organizations use the Internet to collect ideas, solve complex cognitive problems, and build high-quality repositories (e.g., Wikipedia) by self-organizing agents around data and knowledge. Many recent studies have highlighted the factors and the small sets of parameters that play a role when a large crowd interacts with an organization. However, no comprehensive simulation has yet been developed to incorporate all these parameters, investigate Artificial Life phenomena such as emergence and self-organization and potentially generate predictive power. Based on a presentation at ALIFE XII, this paper describes the development of a simulator for human crowds performing collective problem solving in a Crowdsourcing scenario. It details the mechanics of a multi-agent system (MAS) by building on insights from empirical science in several disciplines. The simulator allows running sensitivity analyses of multiple parameters as well as simulation of intractable interactions of complex networks of irrational agents. In addition, the paper provides a review of Crowdsourcing and human collective intelligence literature structured from an Alife point-of-view.
Ultrabroad Bandwidth of Optical Parametric Amplifiers (2010)

KEGG Mapper for inferring cellular functions from protein sequences (2019)

KEGG is a reference knowledge base for biological interpretation of large-scale molecular datasets, such as genome and metagenome sequences. It accumulates experimental knowledge about high-level functions of the cell and the organism represented in terms of KEGG molecular networks, including KEGG pathway maps, BRITE hierarchies, and KEGG modules. By the process called KEGG mapping, a set of protein coding genes in the genome, for example, can be converted to KEGG molecular networks enabling interpretation of cellular functions and other high-level features. Here we report a new version of KEGG Mapper, a suite of KEGG mapping tools available at the KEGG website (https://www.kegg.jp/ or https://www.genome.jp/kegg/), together with the KOALA family tools for automatic assignment of KO (KEGG Orthology) identifiers used in the mapping.
Influence of Blend Composition and Compatibilizer on Mechanical and Morphological Properties of Recycled HDPE/PET Blends (2014)

Polymer blends based on recycled high density polyethylene (rHDPE) and recycled poly(ethylene terephthalate) (rPET) with and without ethylene-glycidyl methacrylate copolymer (E-GMA) as compatibilizer were fabricated in a co-rotating twin screw extruder. The effects of rPET and compatibilizer content on the mechanical properties and morphological stability of rHDPE-rich blends were investigated. The rHDPE/rPET (75/25 wt/wt) blend compatibilized with 5 php (per 100 part of polymer) E-GMA showed an enhancement of about 7% - 26% in tensile properties and flexural strength as compared with those of the neat rHDPE. The strain at break showed a decreasing trend as the rPET content increased. The addition of E-GMA to the rHDPE/rPET blends was found to recover the blend toughness as well as improving the compatibility between HDPE and PET. In this study, the highest strain at break was obtained for the rHDPE/rPET blends at 75/25 (wt/wt) composition with E-GMA content of 5 php. FTIR and SEM analysis of the compatibilized blends confirmed the chemical interaction and improved interfacial bonding between the two phases.

The Use of the VOF‐Model to Study the Wetting of Solid Surfaces (2004)

Abstract The laminar liquid rivulet flow on an inclined flat metal plate and wavy metal plate is taken as a test case to validate the CFD‐simulation results using the VOF (Volume of Fluid) multiphase flow model. The local rivulet thickness was measured using an optically assisted mechanical sensor and compared with the simulation results. The circular shape of the rivulet profile has been proven for an inclined plate. Glycerin water mixtures with different concentrations were used in the experiments. Two theoretical models to describe this laminar rivulet flow in comparison to the experimental and CFD results are discussed.

Object recognition based on graph matching implemented by a Hopfield-style neural network (1989)

A model-based object recognition technique is presented. For each model, distinct features such as curvature points are extracted, and a graph consisting of a number of nodes connected by arcs is constructed. Therefore, each node in the graph represents a feature that has an assigned feature type and a numerical feature value, and an arc between two nodes shows the relationship or compatibility between the features such as distances between feature points. Objects recognition is formulated as matching a model graph with an input image graph. A Hopfield binary network is implemented to perform a subgraph isomorphism to obtain optimum compatible matching features between graphs. The compatibility is defined so that it will tolerate the ambiguity of preprocessed features. The algorithm is also extended to detect one object among several objects which could be touching or overlapping. Some simulation results are shown to evaluate the performance of the system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

The Opacity of Nearby Galaxies from Counts of Background Galaxies. II. Limits of the Synthetic Field Method (2003)

Recently, we have developed and calibrated the Synthetic Field Method (SFM) to derive the total extinction through disk galaxies. The method is based on the number counts and colors of distant background field galaxies that can be seen through the foreground object, and has been successfully applied to NGC 4536 and NGC 3664, two late-type galaxies located, respectively, at 16 and 11 Mpc. Here, we study the applicability of the SFM to HST images of galaxies in the Local Group, and show that background galaxies cannot be easily identified through these nearby objects, even with the best resolution available today. In the case of M 31, each pixel in the HST images contains 50 to 100 stars, and the background galaxies cannot be seen because of the intrinsic granularity due to strong surface brightness fluctuations. In the LMC, on the other hand, there is only about one star every six linear pixels, and the lack of detectable background galaxies results from a ``secondary'' granularity, introduced by structure in the wings of the point spread function. The success of the SFM in NGC 4536 and NGC 3664 is a natural consequence of the reduction of the intensity of surface brightness fluctuations with distance. When the dominant confusion factor is structure in the PSF wings, as is the case of HST images of the LMC, and would happen in M 31 images obtained with a 10-m diffraction- limited optical telescope, it becomes in principle possible to improve the detectability of background galaxies by subtracting the stars in the foreground object. However, a much better characterization of optical PSFs than is currently available would be required for an adequate subtraction of the wings. Given the importance of determining the dust content of Local Group galaxies, efforts should be made in that direction.
Genetic Male Sterility for Hybrid Seed Production in Wheat (1970)

Partially male sterile stocks possessing different degrees of seed set ranging from 5 to 65% have been developed in wheat ( Triticum aestivum L.). The degree of male sterility in these stocks is known to depend upon the cumulative effect of three recessive genes. It is proposed to use the stock with 5% seed set as the female for hybrid seed production. This stock can be maintained in isolation and its use would eliminate the necessity of restorer genes in pollinator lines.

Union mounts in 4.4BSD-lite (1995)

This paper describes the design and rationale behind union mounts, a new filesystem-namespace management tool available in 4.4BSD-Lite. Unlike a traditional mount that hides the contents of the directory on which it is placed, a union mount presents a view of a merger of the two directories. Although only the filesystem at the top of the union stack can be modified, the union filesystem gives the appearance of allowing anything to be deleted or modified. Files in the lower layer may be deleted with whiteout in the top layer. Files to be modified are automatically copied to the top layer.

This new functionality makes possible several new applications including the ability to apply patches to a CD-ROM and eliminate symbolic links generated by an automounter. Also possible is the provision of per-user views of the filesystem, allowing private views of a shared work area, or local builds from a centrally shared read-only source tree.
