Perception of Motion-Adaptive Color Images Displayed by a High-Speed DMD Projector (2019)

Recent progress of high-speed projectors using DMD (Digital Micromirror Device) has enabled low-latency motion adaptability of displayed images, which is a key challenge in achieving projection-based dynamic interaction systems. This paper presents evaluation of different approaches in achieving fast motion adaptability with DMD projectors through a subjective image evaluation experiment and a discrimination experiment. The results suggest that the approach proposed by the authors, which updates the image position for every binary frame instead of for every video frame, applied to 60-fps video input offers perceptual image quality comparable with the quality offered by 500-fps projection.
Saponins from Vietnamese Ginseng, Panax vietnamensis HA et GRUSHV. Collected in Central Vietnam. I. (1993)

From rhizomes and roots of Panax vietnamensis HA et GRUSHV., Araliaceae, commonly known as Vietnamese Ginseng, two new acetylated saponins named vina-ginsenoside-R1 (13) and vina-ginsenoside-R2 (15) were isolated. On the basis of chemical and spectral data, 13 was formulated as monoacetyl 24(S)-pseudo-ginsenoside-F11 and 15 was proved to be monoacetyl majonoside-R2.Besides the two new saponins and β-sitosteryl-3-O-β-D-glucopyranoside, sixteen known saponins were also isolated and identified. Dammarane saponins : ginsenoside-Rh1 and 20(R)-ginsenoside-Rh1 (1), ginsenosides-Rg1 (2), -Re (3), -Rd(6), -Rb3 (7), -Rb2 (8), -Rb1 (9), pseudo-ginsenoside-RS1 (=monoacetyl ginsenoside-Re, 4), notoginsenosides-R1 (5) and -Fa (10). Ocotillol-type saponins : pseudo-ginsenoside-RT4 (11), 24(S)-pseudo-ginsenoside-F11 (12), majonosides-R1 (16) and -R2 (14). Oleanolic acid saponins : ginsenoside-Ro (=chikusetsusaponin V, 17) and hemsloside-Ma3 (18), a saponin previously isolated from a cucurbitaceous plant, Hemsleya macrosperma C. Y. WU.Despite having large horizontally elongated rhizomes, the underground part of this plant contains mainly dammarane saponins and a small amount of oleanolic acid saponins. In addition, the yield of ocotillol-type saponins, especially majonoside-R2, is surprisingly very high (more than 5% and ca. half of the total yield of saponin). This characteristic saponin composition has made Vietnamese Ginseng an interesting species among Panax spp.

Frequency response of cross-phase modulation in multispan WDM optical fiber systems (1998)

The spectral characteristics of cross-phase modulation (XPM) in multispan intensity-modulation direct-detection optical systems were investigated both experimentally and theoretically. XPM crosstalk levels and its spectral features were found to be strongly dependent on fiber dispersion and optical signal channel spacing. Interference between XPM-induced crosstalk effects created in different amplified fiber spans is also found to be important to determine the overall frequency response of XPM crosstalk effects.
Structure, Function, and Insights into the Biosynthesis of a Head-to-Head Hydrocarbon in <i>Shewanella oneidensis</i> Strain MR-1 (2010)

A polyolefinic hydrocarbon was found in nonpolar extracts of Shewanella oneidensis MR-1 and identified as 3,6,9,12,15,19,22,25,28-hentriacontanonaene (compound I) by mass spectrometry, chemical modification, and nuclear magnetic resonance spectroscopy. Compound I was shown to be the product of a head-to-head fatty acid condensation biosynthetic pathway dependent on genes denoted as ole (for olefin biosynthesis). Four ole genes were present in S. oneidensis MR-1. Deletion of the entire oleABCD gene cluster led to the complete absence of nonpolar extractable products. Deletion of the oleC gene alone generated a strain that lacked compound I but produced a structurally analogous ketone. Complementation of the oleC gene eliminated formation of the ketone and restored the biosynthesis of compound I. A recombinant S. oneidensis strain containing oleA from Stenotrophomonas maltophilia strain R551-3 produced at least 17 related long-chain compounds in addition to compound I, 13 of which were identified as ketones. A potential role for OleA in head-to-head condensation was proposed. It was further proposed that long-chain polyunsaturated compounds aid in adapting cells to a rapid drop in temperature, based on three observations. In S. oneidensis wild-type cells, the cellular concentration of polyunsaturated compounds increased significantly with decreasing growth temperature. Second, the oleABCD deletion strain showed a significantly longer lag phase than the wild-type strain when shifted to a lower temperature. Lastly, compound I has been identified in a significant number of bacteria isolated from cold environments.
Fast CRC calculation (2002)

The integrity of messages in data communications is always ensured by the addition, at the end of the message, of a frame check sequence (FCS) traveling with the message itself so it can be checked at far end for proper transmission. A cyclic redundancy code (CRC) is employed to generate FCS at one end and check the entire received message (data plus FCS) at the other end. This is the case of frame relay for instance. Asynchronous transfer mode (ATM) even go further not only protecting either the entire message or each cell but also all cell headers that carry routing information. This raises the need for a simple and fast method to calculate CRC. This paper describes a simpler and faster method than the state of the art.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Synthesis, Structure and Transformations of 2-Iminoimidazolidines into Novel Fused Heterocyclic Ring Systems (2006)

Reaction of 2-chloro-4,5-dihydroimidazole (1) with 2-aminobenzylamines (2a-d) afforded 2-[(imidazolidin-2-ylideneamino)methyl]anilines (3a-d) which upon treatment with carbon disulfide gave 2,3-dihydro-12H-imidazo[2',1':4,5][1,3,5]thiadiazino[2,3-b]quinazolin-5-thiones (4a-d) and 3,4-dihydro-1H-quinazolin-2-thiones (5a-c).Analogous reaction of 1 with 2-aminobenzyl alcohol (6) led to the formation of [2-(4,5-dihydro-1H-imidazol-2-ylamino)phenyl]methanol hydrochloride (7) which was transformed into 1-(4H-3,1-benzoxazin-2-yl)imidazolidin-2-thione (8).
Improved high‐performance liquid chromatography of vitamin E vitamers on normal‐phase columns (1993)

Abstract A method is described for improving column stability and reproducibility for analysis of vitamin E vitamers on normal‐phase high‐performance liquid chromatography columns with isooctane/ethyl acetate/acetic acid/2,2‐dimethoxypropane (98.5:0.9:0.85:0.1) mobile phase. Acetic acid in the mobile phase reduced retention times of vitamin E vitamer and increased column stability. A small concentration of 2,2‐dimethoxypropane, which reacts with water to form acetone and methanol, reduced the need for column regeneration and stabilized retention times.

Phonon scattering, thermoelectric power, and thermal conductivity control in a semiconductor-metal eutectic composition (2005)

The thermoelectric power and thermal conductivity of a GaSb-V2Ga5 eutectic composition are studied. A characteristic feature of this composition is the formation of a V2Ga5 metal phase in the form of parallel whiskers in the GaSb semiconductor matrix during planar crystallization. New data are obtained on the scattering of long-wavelength phonons by metal whiskers and control of the thermoelectric power and thermal conductivity in semiconductor-metal eutectic compositions.
A bandwidth allocation scheme on MS/TP protocol (2005)

The use of network-based control has become widespread in building automation systems. BACnet(building automation and control networks) adopts master-slave/ token-passing(MS/TP) protocol as one of its local area networks. This study introduces a bandwidth allocation scheme in the MS/IP protocol. The bandwidth allocation scheme improves the capability of real-time communication of the original MSA IT protocol. The bandwidth allocation scheme introduced in this paper can he easily implemented in the existing MS/TP protocol with a slight modification. In this study, we examined the validity of bandwidth allocation scheme using simulation models. The results from the simulation experiment show that the proposed scheme satisfies the requirements of real-time communication.
REACTIONS WITH CYANOTHIOACETAMIDE DERIVATIVES: SYNTHESIS AND REACTIONS OF SOME PYRAZOLO[3,4-<i>b</i>]PYRIDINE DERIVATIVES (1992)

Abstract The ylidene derivatives of cyanothioacetamide 1a–d reacted with ethyl acetoacetate to give the pyridinethiol derivatives 2a–d. Compounds 2a–d were used as starting material for the synthesis of several heterocyclic compounds. Reactions with hydrazine hydrate, ethyl iodide, methyl chloroacetate and α-chloro ethyl acetoacetate gave the pyridine and annelated pyridine derivatives 5a–d, 6a–d, 7a, 8b–d, and 12a–d, respectively. Compounds 7a, 8b–d and 12a–d reacted with hydrazine hydrate to yield the annelated pyridines 10a–d and 15a–d, respectively.
Interleukin-12 mediates resistance to Trypanosoma cruzi in mice and is produced by murine macrophages in response to live trypomastigotes (1996)

Host resistance to infection by Trypanosoma cruzi is dependent on both natural and acquired immune responses. During the first week of infection in mice, NK cell-derived gamma interferon (IFN-gamma) is involved in controlling intracellular parasite replication, mainly through the induction of NO biosynthesis by activated macrophages. Interleukin-12 (IL-12) has been shown to be a powerful cytokine in inducing IFN-gamma synthesis by NK cells, as well as in mediating resistance to different intracellular protozoa. We have therefore studied the ability of T. cruzi to elicit IL-12 synthesis by macrophages and the role of this cytokine in controlling parasite replication during acute infection in mice. Our results show that macrophages cultured in the presence of live trypomastigote forms (but not epimastigotes) release IL-12 that can induce IFN-gamma production by normal spleen cells. IL-12 was detected in as little as 12 h after the addition of the trypomastigotes, and the level of IL-12 peaked at 48 h after the initial macrophage-parasite incubation. The addition of anti-IL-12 monoclonal antibody to macrophage-trypomastigote supernatants dose-dependently inhibited IFN-gamma production by naive splenocytes. Finally, the in vivo role of IL-12 in resistance to infection by T. cruzi was analyzed. Mice treated with anti-IL-12 monoclonal antibody had significantly increased parasitemia and mortality in comparison with those of control infected mice treated with control antibody. Together, these results suggest that macrophage-derived IL-12 plays a major role in controlling the parasitemia in T. cruzi-infected mice and that the animal's resistance during the acute phase of infection may, at least in part, be a consequence of postinfection levels of IL-12.
Effect of Age on the Frequency of Active Campylobacter pylori Infection Diagnosed by the [13]Urea Breath Test in Normal Subjects and Patients with Peptic Ulcer Disease (1988)

We studied the frequency of active Campylobacter pylori infection in persons from North America (n = 53) or the People's Republic of China (n = 15) who had no gastrointestinal symptoms or a history of ulcer disease and in patients with active or recently active duodenal or gastric ulcers diagnosed by endoscopy (n = 105). C. pylori infection was significantly (P less than .001) more frequent in patients with peptic ulcers (88%) than in the normal group (45%). An age-related increase in the frequency of C. pylori infection in subjects with no gastrointestinal symptoms paralleled the known age-related increase in prevalence of gastritis. The frequency of C. pylori infection in patients with duodenal ulcers was greater than 80%, irrespective of age. C. pylori infection was more common in the Chinese group (age, 20-39 y) than in the North American group of the same age (60% vs. 24%). Association of C. pylori with specific diseases should not be inferred without knowing the prevalence of C. pylori infection in reference populations of the same age and ethnic background.
Physical mechanisms for short channel effects in polysilicon thin films transistors (2003)

It is demonstrated that channel avalanched multiplication is the dominant mechanism giving rise to short-channel threshold shifts in n- and p-channel polysilicon thin-film transistors (TFTs) at moderate or high drain bias. The effects are greater in nMOS TFTs than pMOS due to the higher ionization rates for electrons in comparison to holes. At low drain bias, a charge sharing mechanism dominates and p-channel devices show greater threshold shifts. Device design parameters such as gate oxide or active island thickness have little influence, and the most effective method for reducing the threshold shifts is to reduce the supply voltage. When the supply voltage is scaled to maintain a fixed minimum threshold voltage, CMOS circuit speeds decrease at shorter gate lengths when a fixed capacitive load is driven, although in more complex circuits the speed improves.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Mantle cell lymphoma: evolving management strategies (2014)

Mantle cell lymphoma (MCL) is a rare and aggressive form of non-Hodgkin's lymphoma that generally affects older individuals and continues to have one of the worst outcomes of all the lymphomas. Over the last decade, there has been a widespread adoption of cytarabine-based therapy in younger patients, and the incorporation of rituximab into chemotherapeutic regimens has become an evidence-based standard of care. However MCL remains a largely incurable disease, and following relapse, it can be a challenge to manage. Although it is possible to define prognosis reliably, there are, as yet, no clear diagnostic or response-adjusted parameters that can help to guide therapeutic decisions. However, there are a number of highly active targeted therapies that are moving into the clinic that are set to transform the therapeutic paradigm for this disease in the very near future. This review will explore the molecular pathogenesis of MCL and the current and evolving therapeutic strategies for this disease.
Explosive Growth in Biased Dynamic Percolation on Two-Dimensional Regular Lattice Networks (2009)

The growth of two-dimensional lattice bond percolation clusters through a cooperative Achlioptas type of process, where the choice of which bond to occupy next depends upon the masses of the clusters it connects, is shown to go through an explosive, first-order kinetic phase transition with a sharp jump in the mass of the largest cluster as the number of bonds is increased. The critical behavior of this growth model is shown to be of a different universality class than standard percolation.

Embedding type structure in semantics (1985)

We show how a programming language designer may embed the type structure of a programming language in the more robust type structure of the typed lambda calculus. This is done by translating programs of the language into terms of the typed lambda calculus. Our translation, however, does not always yield a well-typed lambda term. Programs whose translations are not well-typed are considered meaningless, that is, ill-typed. We give a conditionally type-correct semantics for a simple language with continuation semantics. We provide a set of static type-checking rules for our source language, and prove that they are sound and complete: that is, a program passes the typing rules if and only if its translation is well-typed. This proves the correctness of our static semantics relative to the well-established typing rules of the typed lambda-calculus.
Experiences in implementing a distributed object platform for multimedia applications (2000)

Two current trends in distributed computing are the emergence of standardized distributed object platforms such as CORBA, and the increasing use of continuous media data types. This paper describes and evaluates a platform which supports both standard CORBA interactions and continuous media interactions in a fully integrated environment. The platform is implemented as a self-contained support infrastructure (GOPI core) and a separate ‘personality’ that sits on top of the infrastructure and provides a CORBA API. The platform user can create both request/reply oriented and stream oriented bindings with quality of service specifications that are honoured (as far as possible) by the infrastructure. A framework for quality of service management which involves the monitoring and adaptation of quality levels is also supported. The level of performance attained by the platform provides evidence of the feasibility of natively supporting continuous media in a distributed object platform environment.

Wafer Scale Packaging of MEMS by Using Plasma-Activated Wafer Bonding (2005)

Plasma-assisted direct bonding has been investigated for wafer scale encapsulation of microelectromechanical systems (MEMS). Direct bonding requires smooth and flat wafer surfaces, which is seldom the case after fabrication of MEMS devices. Therefore, we have used polished chemical vapor deposited oxide as an intermediate bonding layer. The oxide layer is polished prior to bonding the MEMS wafer to cap silicon wafer. The bonding is carried out with plasma-assisted direct wafer bonding at a low temperature . Two different methods to form electrical contacts to the encapsulated device are presented. In the first method trenches are etched on the surface of the cap wafer before the bonding. During the bonding the trenches are aligned to the contact pads of the device wafer. After bonding the cap wafer is thinned down with grinding until the path to the contact pads is opened. In the second method one or both of the wafers are thinned down to around after bonding. The electrical path to contact pads is formed using V-groove sawing, metal sputtering, and lithography. To test the viability of the developed methods for MEMS encapsulation, we have sealed polysilicon resonator structures at a wafer level.
