Data Management in Voronoi-Based P2P Gaming (2008)

This paper proposes a fully distributed architecture to support massively multiplayer games (MMGs) on a peer-to-peer (P2P) overlay network. P2P networks provide a scalable and robust solution for MMGs. Furthermore, similarly to real world interactions, MMG players interact with their surrounding, i.e., with visible players and objects in the virtual world. Thus, self-organization of peers based on their visibility property is essential for efficient overlay network support in MMGs. Also, the overlay network must be re-organized consistently in the face of players' position changes. In this paper, we achieve these goals by designing a peer-to-peer overlay network based on the Voronoi diagram. Each player has a responsibility region that includes nearby objects, and is responsible for updates' dissemination occurring in this region to provide game state consistency among the players who are concerned by the updates. As a proof of concept, we simulated a simple game application to demonstrate the feasibility of our architecture.
Highly bright water-soluble silica coated quantum dots with excellent stability (2014)

Silica coating via a Stöber method is an effective route to render luminescent quantum dots (QDs) with great biocompatibility, low toxicity and water-solubility for bioapplications. However, the bottleneck in this route is the access of highly luminescent, colloidally stable QD dispersion in alcoholic solution. Herein, we report a facile route based on the Stöber method for the synthesis of isolated silica coated QDs (QD@SiO<sub>2</sub>) with high emission efficiencies, tunable small size (less than 30 nm) and excellent stability. Prior to silica coating, the initial oil-soluble QDs were made dispersible in alcohol-water media by replacing the native hydrophobic ligands with adenosine 5'-monophosphate (AMP). Then, 3-mercaptopropyl-trimethoxysilane (MPS) was introduced to serve as silane nucleation primers. Finally, a silica shell with controllable thickness was obtained on the QD surface by hydrolysis/condensation of tetraethyl orthosilicate (TEOS). Remarkably, the resultant QD@SiO<sub>2</sub> had nearly the same high luminescent efficiency (50-65%) as that of initial oil-soluble QDs and exhibited excellent long-term photo and colloidal stability in harsh environments (pH range of 3-13, saturated NaCl solution and thermal treatment at 100 °C). It was demonstrated that the cytotoxicity of the resultant QD@SiO<sub>2</sub> was significantly diminished. Moreover, the QD@SiO<sub>2</sub> conjugated with folic acid exhibits high specific binding toward receptor-positive Hela cells over receptor-negative A549 cells, indicating the potential of our obtained QD@SiO<sub>2</sub> as robust biomarkers in cells due to their chemical processibility and low cytotoxicity.
Anti‐invasion effects of 6‐shogaol and 6‐gingerol, two active components in ginger, on human hepatocarcinoma cells (2010)

These results suggest that 6-shogaol and 6-gingerol might both exert anti-invasive activity against hepatoma cells through regulation of MMP-9 and TIMP-1 and that 6-shogaol could further regulate urokinase-type plasminogen activity.
Preparation of 8-(Arylsulfanyl)adenines with Diazonium Salts under Mild, Aerobic Conditions (2004)

8-(Arylsulfanyl)adenines 11 were prepared in up to 75% yield by reacting the 8-thionoadenine 6 (acetic acid 3-(6-amino-8-thioxo-7,8-dihydropurin-9-yl)propyl ester) with benzenediazonium tetrafluoroborates in DMSO. Benzenediazonium ions carrying an electron-withdrawing substituent gave the highest yields. The reaction proceeded smoothly at room temperature without any base and could be performed under air atmosphere. The extremely mild conditions are compatible with a wide range of functional groups.

Wildlife habitat and economic institutions: feast or famine for hunters and game. (1984)

"In Montana, few issues generate higher emotions than wildlife and hunting issues. The right of free access to game is often assumed to be a God-given, natural right. Unfortunately, the reality check of population pressures is challenging these conceptions. We recognize that many of the alternatives explored in this paper are highly controversial, but we also believe that clear and dispassionate analysis is preferable to frustration punctuated by pounding on bar tables.\n\n"Montana is indeed a treasure state, but its primary treasures are not restricted to commodities. Its aesthetic and environmental qualities are of immense value and are increasing in worth. Given that wildlife is a superior good--that is, that demand increases disproportionately with income--and that recreation tends to be non-taxed, we can reasonably expect our wildlife resources to come under increasing pressure.\n\n"The key to meeting increased demand lies with improved management. The question is what set of institutions will generate incentives for managers to use their land to produce wildlife alongside timber, livestock, and other agricultural products. A system of property rights and private management provides the most efficient, ecologically sensitive, and equitable scheme yet designed. It is this approach that we will explore in this paper."

Facile Synthesis and Characterization of Graphene Nanosheets (2008)

Graphene nanosheets were produced in large quantity via a soft chemistry synthetic route involving graphite oxidation, ultrasonic exfoliation, and chemical reduction. X-ray diffraction and transmission electron microscopy (TEM) observations show that graphene nanosheets were produced with sizes in the range of tens to hundreds of square nanometers and ripple-like corrugations. High resolution TEM (HRTEM) and selected area electron diffraction (SAED) analysis confirmed the ordered graphite crystal structure of graphene nanosheets. The optical properties of graphene nanosheets were characterized by Raman spectroscopy.
An epitaxial GaAs field-effect transistor (1967)

Electrical characteristics of an epitaxial GaAs FET are reported. The device is of an interdigitated structure, employing alloyed evaporated metal source and drain contacts, and an evaporated Schottky barrier gate. Transconductance of the order of 20 millimhos is obtained, a factor of ∼5 better than a silicon device of identical geometry. A cutoff frequency of ∼3 GHz is obtained. The device characteristics demonstrate the feasibility of such a device for use at microwave frequencies.
Disruption of Microbial Cells by the Flash Discharge of High-pressure Carbon Dioxide (1994)

In order to develop a novel sterilization method for heat-sensitive materials, the disruption of microbial cells by the rapid release of gas pressure was examined under various conditions of pressure, temperature, treatment time and water content of the cells. Wet cells of baker's yeast were completely destroyed, after the microorganisms had been saturated with CO2 gas at 40°C and 40 atm for more than 3h when the pressure was suddenly discharged. On the other hand, dry cells were poorly killed even under the same experimental conditions. In particular, N2 gas with low solubility in water had no effect on the survival ratio of the yeast. From these results, the death of microorganisms may be caused by mechanical breakage and/or physiological damage related to gas sorption and desorption by the cells.
Imaging the Probe Skirt in the Environmental SEM (2000)

Abstract In low vacuum scanning electron microscopes, the primary beam is partially scattered by the gas present in the specimen chamber. The development of these microscopes, in particular the so-called ‘Environmental’ SEM, was initiated when it was realized that this scattering does not necessarily compromise the imaging capabilities of the instrument. Indeed, some modern commercial instruments are capable of better than 2 nanometer resolution at gas pressures of several torr. The accepted explanation for this is as follows: The mean-free-path of the high energy primary electrons is several millimeters in one torr of water vapour (for example). Because the actual pathlength of electrons travelling through the gas is only a few millimeters, most of them do not scatter at all. Those that do scatter are supposedly distributed over a relatively large area. Thus, the probe features a high-intensity central region surrounded by a slowly decaying low-intensity skirt. High resolution imaging is possible because the signal-to-(skirt)background ratio is high.
Daylight Redirecting Window Films (2013)

Abstract : Daylight redirecting films were produced in a roll-to-roll format. The films were installed in six DoD buildings scattered across three broadly different climate zones. The key performance objective and results are summarized in this report. Significant findings from this study are also included.
Differential effect of cyclosporin A on the expression of T and B lymphocyte activation antigens. (1984)

We have used a monoclonal antibody (Mab) to the interleukin 2 (IL 2) receptor as well as a Mab to the transferrin receptor to analyze the effects of cyclosporin A (CsA) on the induction and expression of these activation antigens on mitogen-stimulated murine T and B lymphocytes. The same concentration (0.25 microgram/ml) of CsA that produced optimal inhibition of the T cell proliferative response to concanavalin A (Con A) was also very effective at inhibiting IL 2 production and the induction of IL 2 responsiveness, as well as the expression of the IL 2 and transferrin receptors when measured 72 hr after mitogen activation. Surprisingly, CsA only minimally inhibited expression of these receptors 24 hr after the addition of mitogen; however, T cell blasts recovered from these cultures failed to respond to IL 2 even though IL 2 receptor expression was only modestly decreased. These results suggest that inhibition of the maturation of receptor expression is secondary to an early effect of CsA in blocking the induction of IL 2 responsiveness or to an arrest in the sequence of events required for maturation of T cells that bear high densities of these receptors. In contrast to the results observed with T lymphocytes, CsA had no effect on the B cell proliferative response to lipopolysaccharide (LPS) or on the induction of the IL 2 and transferrin receptors on activated B lymphocytes.
Power Management and Distribution System for a More-Electric Aircraft (MADMEL) - Program Status (1999)

<div class="htmlview paragraph">A number of technology breakthroughs in the past ten years rekindled the concept of a more-electric aircraft. High-power solid-state switching devices, electrohydro-static actuators (EHAs), electromechanical actuators (EMAs), and high-speed generators are just a few examples of component developments. These developments have made dramatic improvements in properties such as weight, size, power, and cost. However, these components cannot be applied piecemeal. A complete, and somewhat revolutionary, system design approach was needed to exploit the benefits that a more-electric aircraft can provide. Traditional-mounted auxiliary drives, and bleed air extraction will disappear, to be replaced with integral engine starter/generators and electrically driven actuators and pumps.</div> <div class="htmlview paragraph">A five-phase Power <u>Ma</u>nagement and <u>D</u>istribution System for a <u>M</u>ore-<u>E</u>lectric Aircraft (MADMEL) program was awarded by the Air Force to Northrop/Grumman Military Aircraft Division in September 1991. The objective of the program is to design, develop, and demonstrate an advanced electrical power generation and distribution system for a More-Electric Aircraft (MEA). The MEA emphasizes the use of electrical power in place of hydraulics, pneumatic, and mechanical power to optimize the performance and life cycle cost of the aircraft. This paper presents an overview of the MADMEL program and a top-level summary of the program results, development and test of major components to date. In Phase I and Phase II studies, the electrical load requirements were established and the electrical power system architecture was defined for both near-term (NT-year 1996) and far-term (FT-year 2003) MEA application. The detailed design and specification for the Electrical Power System (EPS), its interface with the Vehicle Management System, and the test set-up were developed under Phase III. Phase IV, fabrication and testing of the subsystem level hardware, has been completed. The overall system level integration and testing, Phase V, is scheduled to be completed by September 1999.</div>
Magnetic Glyco-Nanoparticles: A Tool To Detect, Differentiate, and Unlock the Glyco-Codes of Cancer via Magnetic Resonance Imaging (2010)

Within cancer, there is a large wealth of diversity, complexity, and information that nature has engineered rendering it challenging to identify reliable detection methods. Therefore, the development of simple and effective techniques to delineate the fine characteristics of cancer cells can have great potential impacts on cancer diagnosis and treatment. Herein, we report a magnetic glyco-nanoparticle (MGNP) based nanosensor system bearing carbohydrates as the ligands, not only to detect and differentiate cancer cells but also to quantitatively profile their carbohydrate binding abilities by magnetic resonance imaging (MRI). Using an array of MGNPs, a range of cells including closely related isogenic tumor cells, cells with different metastatic potential and malignant vs normal cells can be readily distinguished based on their respective "MRI signatures". Furthermore, the information obtained from such studies helped guide the establishment of strongly binding MGNPs as antiadhesive agents against tumors. As the interactions between glyco-conjugates and endogenous lectins present on cancer cell surface are crucial for cancer development and metastasis, the ability to characterize and unlock the glyco-code of individual cell lines can facilitate both the understanding of the roles of carbohydrates as well as the expansion of diagnostic and therapeutic tools for cancer.
Influence of Propranolol on the Ventricular Depolarization Gradient (1991)

Sensing of the ventricular depolarization gradient (VDG) has recently been used as the basis of a closed-loop rate responsive pacemaker. Factors influencing this aspect of the evoked response have not been fully evaluated although previous reports have suggested that sympathetic stimulation and circulating catecholamines are primarily responsible for the observed changes during stress and exercise. In five patients (Table I), four males and one female (mean age 60.4 +/- 10.1 years) implanted with the Prism pacemaker, the pacing response to exercise and tilting was assessed before and after the infusion of propranolol. There was an increase in the pacing rate in all patients during the infusion of the drug (mean 27 +/- 12.9 beats/min) suggestive of a direct drug effect on the VDG. The rate control parameter (RCP) of the pacemaker, the numerical equivalent of the VDG, was significantly different after the administration of propranolol (P less than 0.01). However, exercise performance and pacing rate behavior were not different after beta blockade. The pacing rate increase observed when tilting patients to the supine position was not altered by propranolol. Out date suggest that factors other than adrenergic stimulation may be of importance in affecting the ventricular evoked response and accordingly the rate adaptation of the Prism pacemaker.
Exploiting Nonneural Cells to Rebuild the Nervous System: From Bone Marrow to Brain (2000)

Bone marrow, in addition to hematopoietic precursors, contains cells that are considered stem cells of nonhematopoietic tissues. These cells are referred to as marrow stromal cells or mesenchymal stem cells. Marrow stromal cells, because of their ability to survive, integrate, and migrate within the central nervous system, can be used as an alternative source of cells for neural transplantation and repair. They can be expanded rapidly in culture and can be induced to express markers of neural cells. Moreover, implanted into the developing brain, these cells can integrate without disrupting the host brain architecture and can assume the fate of neural cells. They can be genetically transduced and can elaborate transgene products. Because large numbers of stromal cells can be obtained from small aspirates of bone marrow, these cells are potentially useful for treating a variety of neurological diseases.
A High-Speed SDM-MIMO Decoder Using Efficient Candidate Searching for Wireless Communication (2008)

In this brief, a high-speed space-division multiplexing (SDM) multiple-input-multiple output (MIMO) decoder using efficient candidate searching is proposed by exploiting the characteristics of QR decomposition and sphere decoder for high throughput rate and low hardware-complexity. A process of efficient candidate searching by shifting the center of constellation with scalable radius reduces the processing time and improves the operational frequency. The proposed architecture can operate at a 166-MHz clock frequency, and the core area is smaller than results from using the K-best SD algorithm since large memory is not required to store extreme candidate paths. In our implementation, the core area is 0.675 mm using TSMC 90-nm technology. The average throughput of the proposed SDM-MIMO decoder is 95 Mbps with 64-QAM modulation at 30-dB signal-to-noise ratio.
Film Architecture in Biomolecular Assemblies. Effect of Linker on the Orientation of Genetically Engineered Surface-Bound Proteins (1996)

This contribution presents strategies for the optimization of supramolecular architecture aimed at controlling the organization of biomolecules at solid surfaces. Myoglobin, modified by site-directed mutagenesis to include a unique cysteine residue, is selectively chemisorbed to self-assembled haloalkylsilylated silica surfaces of varying n-alkyl chain length (n = 2, 3, 8, 11, 15) to yield a series of surface-immobilized recombinant protein assemblies. These supramolecular assemblies are probed using tapping mode atomic force microscopy, wettability measurements, Fourier transform infrared spectroscopy, and linear dichroism spectroscopy to determine how the individual components comprising these structures (substrate, silane coupling layer, and protein) influence macromolecular protein ordering and stability. Surface roughness is found to be a minor contributor in the determination of macromolecular ordering in these assemblies. In contrast, the nature of the underlying silane self-assembled coupling layer is shown to strongly influence both the spatial and functional properties of the chemisorbed protein. Silane coupling layers with short aliphatic chain lengths (n = 2, 3) produce highly trans-conformationally ordered structures upon which differential heme prosthetic group orientation can be achieved. Long alkyl chain (n ≥ 11) silane-derivatized surfaces also form ordered structures. The stability of myoglobin appended to long chain aliphatic silylated surfaces is poor, however. The apparent protein instability arises due to the increased hydrophobic character of these films. At intermediate alkyl chain length (n = 8), a conformationally disordered coupling layer with a high concentration of gauche defects is produced, regardless of the method of silane deposition or postdeposition processing. Chemisorption of myoglobin to the highly disorganized assembly yields a random orientation of the protein.
Favourable pregnancy results with insemination of in vitro matured oocytes from unstimulated patients (2005)

Insemination of IVM oocytes functions well, resulting in comparable pregnancy rates per IOC between IVM-IVF and IVM-ICSI. Good pregnancy results can be achieved both in patients with regular cycles and with PCO(S) by transferring only one or two embryos at a time.
Mediation of Norepinephrine‐Stimulated Cyclic AMP Accumulation by Adrenergic Receptors in Hypothalamic and Preoptic Area Slices: Effects of Estradiol (1987)

Adrenergic receptor agonists and antagonists were employed to establish (a) which receptor subtypes mediate the cyclic AMP response to norepinephrine in hypothalamic and preoptic area slices from gonadectomized female rats and (b) which receptor subtypes might be modulated by the steroid hormone estradiol. Slice cyclic AMP levels were elevated by the beta receptor agonist isoproterenol, but not by alpha 1 (phenylephrine, methoxamine) or alpha 2 (clonidine) agonists. However, the alpha agonist phenylephrine potentiated the effect of the beta agonist isoproterenol on slice cyclic AMP accumulation. In slices from rats given no hormone treatment, the beta antagonist propranolol inhibited norepinephrine-stimulated cyclic AMP production, while the alpha 1 antagonist prazosin was without effect. In contrast, the cyclic AMP response to norepinephrine in slices from estradiol-treated rats was blocked more effectively by prazosin than by propranolol. Estradiol treatment also attenuated the production of cyclic AMP by the beta agonist isoproterenol. The data suggest (a) that norepinephrine induction of cyclic AMP accumulation in hypothalamic and preoptic area slices is mediated by beta receptors and potentiated by alpha receptor activation and (b) that estradiol depresses beta and increases alpha 1 receptor function in slices from brain regions associated with reproductive physiology.
