Photoaffinity labelling of glycosyltransferases (1992)

The photoaffinity analogues 5-azido-UDP-glucose and 5-azido-UDP-glucuronic acid have proven to be valuable biochemical tools in the studies of nucleoside diphosphate sugar-utilizing enzymes, especially membrane-associated glycosyltransferases. A summary of the past and current uses of these analogues is presented, as well as photoaffinity data for the enzyme UDP-glucose: dolichylphosphate glucosyltransferase (Glc-P-Dol synthase). This enzyme has served as a model membrane-associated glycosyltransferase for demonstrating the uses of 5-azido-UDP-glucose. The advantages of using photoaffinity analogues for the purification and characterization of glycosyltransferases are presented, as well as an outline of the general procedures which can be used in conjunction with these analogues.
3D temperature field reconstruction using ultrasound sensing system (2016)

3D temperature field reconstruction is of practical interest to the power, transportation and aviation industries and it also opens up opportunities for real time control or optimization of high temperature fluid or combustion process. In our paper, a new distributed optical fiber sensing system consisting of a series of elements will be used to generate and receive acoustic signals. This system is the first active temperature field sensing system that features the advantages of the optical fiber sensors (distributed sensing capability) and the acoustic sensors (non-contact measurement). Signals along multiple paths will be measured simultaneously enabled by a code division multiple access (CDMA) technique. Then a proposed Gaussian Radial Basis Functions (GRBF)-based approach can approximate the temperature field as a finite summation of space-dependent basis functions and time-dependent coefficients. The travel time of the acoustic signals depends on the temperature of the media. On this basis, the Gaussian functions are integrated along a number of paths which are determined by the number and distribution of sensors. The inversion problem to estimate the unknown parameters of the Gaussian functions can be solved with the measured times-of-flight (ToF) of acoustic waves and the length of propagation paths using the recursive least square method (RLS). The simulation results show an approximation error less than 2% in 2D and 5% in 3D respectively. It demonstrates the availability and efficiency of our proposed 3D temperature field reconstruction mechanism.
Design of a Prism to Compensate the Image-shifting Error of the Acousto-optic Tunable Filter (2008)

The Acousto-Optic Tunable Filter (AOTF) is a high-speed full-field monochromator which generates two spectrally filtered light beams with ordinary and extraordinary polarization state. The AOTF is widely used to build full-field spectral imaging systems or a spectral domain interferometer. The angle of diffracted light in the AOTF changes according to the scanning of wavelength, which causes an image shift on the CCD plane. An analytic design of a prism system to compensate for the image shift is proposed in this paper. Analysis of light paths in a prism and experimental results verified a proposed compensation method. Experimental results agreed with simulation results based on the suggested prism model. Image shifting errors of ordinary and extraordinary rays were simultaneously minimized at optimal conditions with the designed prism.
Synthesis of phosphonate-functionalized polystyrene and poly(methyl methacrylate) particles and their kinetic behavior in miniemulsion polymerization (2009)

Phosphonate-functionalized polymer nanoparticles were synthesized by free-radical copolymerization of vinylphosphonic acid (VPA) with styrene or methyl methacrylate (MMA) using the miniemulsion technique. The influence of different parameters such as monomer and surfactant type, amount of vinylphosphonic acid on the average particle size, and size distribution was studied using dynamic light scattering and transmission electron microscopy. Depending on the amount and type of the surfactant used (ionic or non-ionic), phosphonate-functionalized particles in a size range from 102 to 312 nm can be obtained. The density of the phosphonate groups on the particle surface was higher in the case of using MMA as a basis monomer than polystyrene. The kinetic behavior of VPA copolymerization with styrene or MMA using a hydrophobic initiator was investigated by reaction calorimetry. Different kinetic curves were observed for miniemulsion (co)polymerization of styrene- and MMA-based nanoparticles indicating different nucleation mechanisms.

Xylem cell death: emerging understanding of regulation and function (2012)

Evolutionary, as well as genetic, evidence suggests that vascular development evolved originally as a cell death programme that allowed enhanced movement of water in the extinct protracheophytes, and that secondary wall formation in the water-conducting cells evolved afterwards, providing mechanical support for effective long-distance transport of water. The extant vascular plants possess a common regulatory network to coordinate the different phases of xylem maturation, including secondary wall formation, cell death, and finally autolysis of the cell contents, by the action of recently identified NAC domain transcription factors. Consequently, xylem cell death is an inseparable part of the xylem maturation programme, making it difficult to uncouple cell death mechanistically from secondary wall formation, and thus identify the key factors specifically involved in regulation of cell death. Current knowledge suggests that the necessary components for xylem cell death are produced early during xylem differentiation, and cell death is prevented through the action of inhibitors and storage of hydrolytic enzymes in inactive forms in compartments such as the vacuole. Bursting of the central vacuole triggers autolytic hydrolysis of the cell contents, which ultimately leads to cell death. This cascade of events varies between the different xylem cell types. The water-transporting tracheary elements rely on a rapid cell death programme, with hydrolysis of cell contents taking place for the most part, if not entirely, after vacuolar bursting, while the xylem fibres disintegrate cellular contents at a slower pace, well before cell death. This review includes a detailed description of cell morphology, function of plant growth regulators, such as ethylene and thermospermine, and the action of hydrolytic nucleases and proteases during cell death of the different xylem cell types.
Laser-assisted blastocyst dissection and subsequent cultivation of embryonic stem cells in a serum/cell free culture system: applications and preliminary results in a murine model (2006)

Achieving successful techniques for human ESC research is fundamentally dependent on preliminary work using experimental animals. In this study, all experimentally developed ESC lines manifested similar features to ESCs obtained from intact blastocysts in standard culture. Cell/sera free murine ESC harvest and propagation are feasible procedures for an embryology laboratory and await refinements for translation to human medical research.

Status Report on Activities of the Systems Assessment Task Force, OECD-NEA Expert Group on Accident Tolerant Fuels for LWRs (2017)

The Organization for Economic Cooperation and Development /Nuclear Energy Agency (OECD/NEA) Nuclear Science Committee approved the formation of an Expert Group on Accident Tolerant Fuel (ATF) for LWRs (EGATFL) in 2014. Chaired by Kemal Pasamehmetoglu, INL Associate Laboratory Director for Nuclear Science and Technology, the mandate for the EGATFL defines work under three task forces: (1) Systems Assessment, (2) Cladding and Core Materials, and (3) Fuel Concepts. Scope for the Systems Assessment task force (TF1) includes definition of evaluation metrics for ATF, technology readiness level definition, definition of illustrative scenarios for ATF evaluation, and identification of fuel performance and system codes applicable to ATF evaluation. The identification of irradiation facilities around the world that are being used, or are planned to be used, for the irradiation testing of ATF cladding and fuel materials was later added to the TF1 scope (April 2017). The Cladding and Core Materials (TF2) and Fuel Concepts (TF3) task forces have worked to identify gaps and needs for modeling and experimental demonstration; define key properties of interest; identify the data necessary to perform concept evaluation under normal conditions and illustrative scenarios; identify available infrastructure (internationally) to support experimental needs; and make recommendations on priorities. Where possible, considering proprietary and other export restrictions (e.g., International Traffic in Arms Regulations), the Expert Group has facilitated the sharing of data and lessons learned across the international group membership. The Systems Assessment task force is chaired by Shannon Bragg-Sitton (Idaho National Laboratory [INL], U.S.), the Cladding Task Force is chaired by Marie Moatti (Electricite de France [EdF], France), and the Fuels Task Force is chaired by a Masaki Kurata (Japan Atomic Energy Agency [JAEA], Japan). The original Expert Group mandate was established for June 2014 to June 2016. In April 2016 the Expert Group voted to extend the mandate one additional year to June 2017 in order to complete the task force deliverables; this request was subsequently approved by the Nuclear Science Committee. All reports are currently in final draft and will be submitted to NEA for final formatting/editing in October 2017. A final EGATFL meeting will be held at NEA Headquarters in Paris, France on November 2-3, 2017 to resolve any final comments on the task force reports. This report provides brief summary of the Systems Assessment Task Force deliverable report.
Comparing complexities of problems of determining of Grebner’s basis of ideal and solving this ideal (2012)

A new method of investigation of ideals in the rings of polynomials was proposed by B. Buchberger in 1965. He proposed to use special basis in such rings named “Gröbner Basis” in the honor of his teacher. The proposed approach has allowed to prove the algorithmic reducibility of the task of finding solutions of a system of algebraic equations in many variables to the problem of solving algebraic equation of one variable. However, the practical use of the method needs enormous computational cost. The first estimate of the computational complexity of this method was obtained by G. Hermann in 1925, when the concept of Gröbner basis was not yet known. Was obtained the required upper estimate in the form of dual exponent of the number of variables and the maximum degree of incoming task description polynomials of degree of decomposition element ideal for an arbitrary basis. As it turned out later by T.W. Dube this estimate cannot be improved. In 1996 K. Kühnle and E. W. Mayr proved, that for Boolean ideals the upper bound of memory capacity is exponential on input size. For zero-dimensional ideals A. Hashemi and D. Lazard proved the exponential complexity of finding Gröbner basis. Here we prove the lower bound of computation of such bases, by giving an example of an ideal having Gröbner basis of exponential size on input.
Sunlight-style color-temperature tunable organic light-emitting diode (2009)

We demonstrate a man-made lighting device of organic light-emitting diode (OLED) capable of yielding a sunlight-style illumination with various daylight chromaticities, whose color temperature ranges between 2300 and 8200 K, fully covering those of the entire daylight at different times and regions. The OLED employs a device architecture capable of simultaneously generating all the emissions required to form a series of daylight chromaticities. The wide color-temperature span may be attributed to that the recombination core therein can easily be shifted along the different emissive zones simply by varying the applied voltage via the use of a thin carrier-modulating layer.
Endocytosis, Endosome Trafficking, and the Regulation ofDrosophilaDevelopment (2006)

Endocytosis and endosome trafficking regulate cell signaling in unexpected ways. Here we review the contribution that Drosophila research has made to this exciting field. In addition to attenuating signaling, endocytosis shapes morphogen gradients, activates ligands, and regulates spatially receptor activation within a single cell. Moreover, some receptors signal from within endosomes, and the ability of a specific type of endosome to form controls the ability of cells to signal. Experiments in Drosophila reveal that through regulation of a variety of cell signaling pathways, endocytosis controls cell patterning and cell fate.

High‐dose monotherapy in treatment of intractable seizures (1984)

We evaluated the therapeutic efficacy and toxicity of high-dose monotherapy, using carbamazepine or phenytoin, in patients with previously uncontrolled seizures. Treatment with a single drug was equal to or better than polypharmacy, but only a few patients became free of seizures. Toxicity was mild and associated with higher total plasma levels after polypharmacy. Free fractions ranged from 0.14 to 0.30 for carbamazepine and from 0.60 to 0.13 for phenytoin. Toxicity was associated with free phenytoin levels above 3 micrograms/ml; there was no clear relationship between free carbamazepine level and toxicity.
A transparent and evolvable licensing object service (2005)

If we put aside any controversy that could surround the issue of licensing a piece of software, we are faced with actual technical problems to solve in order to regulate the use of protected software in a non-intrusive way. A licensing service allows software producers to control the access and use of their products, and enables the customers to pay only for the software functionalities they use. In this paper we present a CORBA licensing service that is transparent to the end-users and that can easily evolve to adapt to changing licensing policies. Design and implementation issues are discussed. Experimental results are provided.
On using JSON-LD to create evolvable RESTful services (2012)

As the amount of data and devices on the Web experiences exponential growth issues on how to integrate such hugely heterogeneous components into a scalable system become increasingly important. REST has proven to be a viable solution for such large-scale information systems. It provides a set of architectural constraints that, when applied as a whole, result in benefits in terms of loose coupling, maintainability, evolvability, and scalability. Unfortunately, some of REST's constraints such as the ones that demand self-descriptive messages or require the use of hypermedia as the engine of application state are rarely implemented correctly. This results in tightly coupled and thus brittle systems. To solve these and other issues, we present JSON-LD, a community effort to standardize a media type targeted to machine-to-machine communication with inherent hypermedia support and rich semantics. Since JSON-LD is 100% compatible with traditional JSON, developers can continue to use their existing tools and libraries. As we show in the paper, JSON-LD can be used to build truly RESTful services that, at the same time, integrate the exposed data into the Semantic Web. The required additional design costs are significantly outweighed by the achievable benefits in terms of loose coupling, evolvability, scalability, self-descriptiveness, and maintainability.
Catalytic Asymmetric Reductive Coupling of Alkynes and Aldehydes:  Enantioselective Synthesis of Allylic Alcohols and α-Hydroxy Ketones (2003)

A highly enantioselective method for catalytic reductive coupling of alkynes and aldehydes is described. Allylic alcohols are afforded with complete E/Z selectivity, generally >95:5 regioselectivity, and in up to 96% ee. In conjunction with ozonolysis, this process is complementary to existing methods of enantioselective alpha-hydroxy ketone synthesis.
The Strength and Toughness of Cast Aluminum Composites as a Function of Composition, Heat Treatment and Particulate (1996)

&lt;div class="htmlview paragraph"&gt;Net-shape aluminum matrix composite components and test specimens were produced through an advanced pressure infiltration process where molten alloys are infiltrated into ceramic preforms. Test specimens were cast with 4 aluminum alloys with alumina and SiC reinforcements. Specimens were heat treated to T6 and T7 conditions and to a special condition wherein intermetallic particles are precipitated at internal interfaces. Alumina reinforced materials were generally stronger and tougher than silicon carbide reinforced materials. Maximum flexure strengths of 653 and 683 MPa were achieved through alumina reinforced 520 and 295 alloys, respectively. Fracture toughness and Charpy impact values were also determined.&lt;/div&gt;
Dynamics of an Electrohydraulic Stepping Motor (1977)

Throughput Performance of Iterative Frequency-Domain SIC with 2D MMSE-FDE for SC-MIMO Multiplexing (2006)

Broadband wireless packet access will be the core technology of the next generation mobile communication systems. For very high-speed and high-quality packet transmissions in a limited bandwidth, the joint use of multiple-input multiple-output (MIMO) multiplexing and hybrid ARQ (HARQ) is an effective method. However, if single-carrier (SC) transmission is used, the transmission performance significantly degrades due to a large inter-symbol interference (ISI) resulting from a severe frequency-selective fading. In this paper, we propose an iterative frequency-domain successive interference cancellation (SIC) with two dimensional (2D) MMSE-FDE. At each iteration stage, the successive signal detection/cancellation is performed according to the descending order of the signal reliability. However, since the interference from the other transmit antennas can be only partially cancelled by performing SIC, the residual interference is present at the output of SIC. In this paper, we propose to update the 2D MMSE-FDE weights at each signal detection in order to suppress simultaneously the ISI and the interference from other antennas while obtaining antenna and frequency diversity gain. However, since a single use of SIC with 2D MMSE-FDE is insufficient, it is repeated a sufficient number of times. The bit error rate (BER) and HARQ throughput performance in a frequency-selective Rayleigh fading channel are evaluated by computer simulation.

A general setting for functions of Fueter variables: differentiability, rational functions, Fock module and related topics (2018)

We develop some aspects of the theory of hyperholomorphic functions whose values are taken in a Banach algebra over a field -- assumed to be the real or the complex numbers -- and which contains the field. Notably, we consider Fueter expansions, Gleason's problem, the theory of hyperholomorphic rational functions, modules of Fueter series, and related problems. Such a framework includes many familiar algebras as particular cases. The quaternions, the split quaternions, the Clifford algebras, the ternary algebra, and the Grassmann algebra are a few examples of them.
Three-dimensional isotropic meta-materials (2005)

This paper addresses the design and construction of metallic structures, whose induced electric and/or magnetic dipole moments are equal in all three principle directions. These materials can be used to make a 3-dimensional, negative-refractive index metamaterial. Meta-materials are constructed of three-dimensional materials, but the electromagnetic response has only been realized in one or two dimensions. In this paper, when we refer to the dimensionality of a material, we mean the number of directions that have equal and non-trivial response to incident fields. We also consider whether a structure has a polarization dependent response. Although Silveririnha (2004) has shown that the periodic square or cubic grids that are used are not truly isotropic in that the response is angle dependant, the same response in all coordinate directions is a good start
