[Changes of cardiac function during +Gz exposure in rabbits]. (1997)

Changes of cardiac function was studied during +Gz exposure in rabbits. Seven New Zealand rabbits were anesthetized and exposed to +2, +4, and +6 Gz (each for 30s, onset rate 1G/s, with 15 min interval in between). The left ventricular systolic pressure (LVSP), peak rate of left ventricular pressure rising (+dp/dtmax) and ECG were recorded. The results showed that during +2, +4 and +6 Gz exposures, LVSP decreased by 62.96% (P<0.01), 63.34% (P<0.01) and 82.01% (P<0.01) respectively, and +dp/dtmax decreased by 58.46% (P<0.01), 53.59% (P<0.01) and 63.06% (P<0.01) respectively, and the left ventricular end diastolic pressure decreased by 67.78 % (P>0.05), 332.74 % (P<0.01) and 500.54% (P<0.01) respectively, as compared with those of control. It is suggested that cardiac function is depressed with +Gz exposure.
Pruning Systems and Canopy Management Practice Interact on the Yield and Fruit Composition of Syrah (2012)

A production trial in the San Joaquin Valley of California was conducted where canopy microclimate of Syrah 05/SO4 grapevines was altered through three pruning systems and two leaf removal treatments arranged factorially to rejuvenate vineyards with declining productivity. Vines were either pruned by hand to 44 nodes each, mechanically box-pruned to a 10 cm hedge, or cane-pruned by hand to six 8-node canes arranged in opposing directions of the row with horizontal canopy separation. Outer surface layer of leaves were either removed mechanically 20 days postbloom on the east side of the canopy in a 45 cm zone above the cordon in the fruit zone or not removed. Yields from spur- and mechanically box-pruned vines were considered too low for the study area, and leaf removal had no effect on yield components. Spur-pruned vines reached 24 Brix earlier than mechanically box-pruned and cane-pruned vines in each year. Leaf removal had no effect on fruit composition of Syrah at harvest. Berry skin phenolics were not consistently affected by treatments applied. Cane pruning resulted in 3.8 leaf layers, with 32 shoots per 30 cm of row, 7.77 kg/kg Ravaz index, and consistently ripened 22 tons/ha to 24 Brix and should therefore be used in the San Joaquin Valley to improve yields in vineyards with declining productivity. The study identified a pruning system for vineyards in warm climates that can sustain yields and provides management information for growers on how to rejuvenate vines that have declined in productivity.
Cdc42 and ARP2/3-independent regulation of filopodia by an integral membrane lipid-phosphatase-related protein (2007)

Filopodia are dynamic cell surface protrusions that are required for proper cellular development and function. We report that the integral membrane protein lipid-phosphatase-related protein 1 (LPR1) localizes to and promotes the formation of actin-rich, dynamic filopodia, both along the cell periphery and the dorsal cell surface. Regulation of filopodia by LPR1 was not mediated by cdc42 or Rif, and is independent of the Arp2/3 complex. We found that LPR1 can induce filopodia formation in the absence of the Ena/Vasp family of proteins, suggesting that these molecules are not essential for the development of the protrusions. Mutagenesis experiments identified residues and regions of LPR1 that are important for the induction of filopodia. RNA interference experiments in an ovarian epithelial cancer cell line demonstrated a role for LPR1 in the maintenance of filopodia-like membrane protrusions. These observations, and our finding that LPR1 is a not an active lipid phosphatase, suggest that LPR1 may be a novel integral membrane protein link between the actin core and the surrounding lipid layer of a nascent filopodium.
Preparation and Properties of Aluminum Nitride Films Using an Organometallic Precursor (1989)

Polycrystalline aluminum nitride films were deposited on silicon and silica substrates at 400°–800°C in a low pressure chemical vapor deposition system using the volatile organometallic precursor, . Under appropriate conditions of substrate temperature and growth rate, the films were transparent, smooth, and highly adherent to the substrate. Auger electron spectroscopy indicated that these films contained close to a one‐to‐one ratio of aluminum to nitrogen and relatively low concentrations of carbon and oxygen. X‐ray and electron diffraction studies showed that the 2H (hexagonal,; ) phase of aluminum nitride was the only crystalline product. Scanning and transmission electron microscopy indicated a dense, polycrystalline microstructure with an grain size range of 0.05–1.00 μm, depending on the deposition conditions. Films deposited on silica at or above 600°C were transparent in the visible and near infrared with an absorption edge of ca. 6.2 eV. Fourier transform infrared spectra of the films on silicon showed the characteristic Al‐N stretching vibration at with relatively weak and broad bands in the N‐H and C‐H stretching region. Current‐voltage and capacitance‐voltage measurements were performed on aluminum nitride films deposited on Si (100), yielding values for the dielectric constant, field breakdown strength, and resistivity. The effects of annealing in a nitrogen atmosphere up to 800°C were studied using UV‐visible and FTIR absorption spectroscopy. The rate of dissolution of the films in phosphoric acid was also determined. These results indicate that can be used as a single‐component precursor for the low pressure deposition of aluminum nitride films at temperatures as low as 500°C, and that the films obtained at or above 600°C have microstructural features and properties appropriate for microelectronic applications.
Fabrication of highly-nanolaminated metal inductor core by pressing and punching (2017)

We present a pressing and punching method for a highly nanolaminate metal-insulator structure as a simple and cost-effective fabrication technique. The proposed nanolaminate metal-insulator structure is suitable for a magnetic core of a solenoid inductor. Cobalt-Nickel-Iron as a soft magnet metal was deposited on a polyethylene film which serves as an insulator. The Cobalt-Nickel-Iron bearing polymer film was folded multiple times and pressed with heat. The pressed sample was then comprised of multiple submicron magnetic metal layers and insulating polymer layers. The sample was cut into pieces by a punching with a predetermined shape and wire-wound for inductor application. Each nanolaminate magnetic layer suppresses the space of the eddy-current while the stacked magnetic layers will provide enough magnetic volume for the performance as an inductor. As a test vehicle, a multilayer structure of submicron Cobalt-Nickel-Iron with polyethylene film as an insulation layer was fabricated and tested. The dimension of the multilayer structure was 4 mm width, 10 mm length, and 3 mm thickness. 3000 layers in a combination of CoNiFe and polyethylene film were formed. A 10-turn with a standard magnet wire was wound to form a solenoid inductor. The test result through an impedance analyzer measurement exhibited an average inductance of 290 nH stably shown up to 100 MHz with peak quality factor of 130 at 95 MHz. The proposed method is a substrate-less process and therefore it is versatile, cost-effective, introducing easing fabrication and reducing processing time while it can achieve thousands of magnetic core layer.
Superconductive radiation detector with large sensitive area (series-connected STJ detector) (1991)

One of the serious problems in the development of particle detectors with superconducting tunnel junctions (STJ) is the difficulty in devising a large area that is sensitive to nuclear radiations. The problem has been solved by using an assembly of micro STJs connected in series (series-connected STJ detector), which is designed for detecting nonthermal phonons created by irradiating the rear substrate (sapphire) with nuclear radiations. The present detector is sensitive not only to ionizing events but also to nonionizing events, providing us with a new method to detect nuclear radiations. Some features of the series-connected STJ detector are described in this article.

Macrolide antibiotics M-4365 produced by Micromonospora. III. In vitro antimicrobial activity of antibiotic M-4365G2(de-epoxy rosamicin). (1978)

Antibiotic M-4365G2 (de-epoxy rosamicin) produced by Micromonospora capillata MCRL 0940 is a new basic 16-membered macrolide antibiotic with activity equal to or superior to erythromycin and josamycin against Gram-positive bacteria. Of interest are the high degree of activity against Gram-negative bacilli and mycoplasmas, and striking inhibitory effects against indole-producing Proteus spp. Bactericidal activity of M-4365G2 is also to be noticed.
Wide $V_{\rm DD}$ Embedded Asynchronous SRAM With Dual-Mode Self-Timed Technique for Dynamic Voltage Systems (2008)

Voltage-dependent timing skews in precharge and sensing activities cause functional failure and reduce the speed of asynchronous static random-access memory (SRAM). Data-dependent bitline-leakage current further increases the timing skews and reduces the yield of asynchronous SRAM. A dual-mode self-timed (DMST) technique is developed for asynchronous SRAM to eliminate the timing-skew-induced failures and speed overhead across various process, voltage, and temperature conditions. The DMST technique employs a single replica column and new dummy cells to track both precharge and sensing activities in asynchronous SRAM, with bitline leakage considered. The DMST-technique simulation uses both 65-nm and 0.35-mum technologies. Several 0.35-mum DMST SRAM macros were fabricated in a test chip and embedded in a mass-produced system-on-a-chip suitable for various battery/supply-voltage configurations. Measurements demonstrated that the DMST technique can be operated continuously over a wide range of supply voltages, from 39.4% to 151.5% (or 212.1%, given device durability) of the nominal supply voltage (3.3 V). The fabricated macros also confirmed that the DMST technique is scalable for various bitline lengths and offers the same area overhead as conventional sense-tracking-only replica-column schemes.
A Deterministic Sequential Monte Carlo Method for Haplotype Inference (2008)

Sets of single nucleotide polymorphisms (SNPs), or haplotypes, are widely used in the analysis of relationship between genetics and diseases. Due to the cost of obtaining exact haplotype pairs, genotypes which contain the unphased information corresponding to the haplotype pairs in the test subjects are used. Various haplotype inference algorithms have been proposed to resolve the unphased information. However, most existing algorithms are limited in different ways. For statistical algorithms, the limiting factors are often in terms of the number of SNPs allowed in the genotypes, or the number of subjects in the dataset. In this paper, we propose a deterministic sequential Monte Carlo-based haplotype inference algorithm which allows for larger datasets in terms of number of SNPs and number of subjects, while providing similar or better performance for datasets under various conditions.
Efficient Integer Frequency Offset Estimation Architecture for Enhanced OFDM Synchronization (2015)

In orthogonal frequency-division multiplexing (OFDM) systems, integer frequency offset (IFO) causes a circular shift of the subcarrier indices in the frequency domain. The IFO can be mitigated through strict RF front-end design, which tends to be expensive, or by strictly limiting mobility and channel agility, which constrains operating scenarios. The IFO is, therefore, often estimated and removed at baseband, allowing implementations to benefit from the relaxed RF front-end specifications and to be tolerant to both Doppler shift and multistandard channel selection. This paper proposes a novel architecture for the IFO estimation which achieves reduced power consumption and lower computational cost than contemporary methods, while achieving excellent estimation performance, close to theoretically achievable bounds. A pilot subsampling technique enables fourfold resource sharing to reduce the computational cost, while multiplierless computation yields further power reduction. Performance exceeds that of the conventional techniques, while being much more efficient. When implemented on field-programmable gate array for IEEE 802.16-2009, the dynamic power reductions of 78% are achieved. The architecture and method is applicable to other OFDM standards including IEEE 802.11 and IEEE 802.22.
Superposition of states by adiabatic passage in<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mrow><mml:mi>N</mml:mi></mml:mrow></mml:math>-pod systems (2011)

We study the stimulated Raman adiabatic passage technique in an $N$-pod system driven by $N$ pulsed fields when $N\ensuremath{-}2$ and $N\ensuremath{-}1$ pulses not connected to the initial state have the same shape. We show that, for properly timed pulses, robust population transfer from an initial ground state to an arbitrary coherent superposition of the ground states can be achieved in a single step. The case of $N\ensuremath{-}2$ pulses of the same shape involves a geometric phase of the same type as the one appearing in tripod systems.
Oral Exposure to Alloantigen Generates Intragraft CD8+ Regulatory Cells (2001)

We have previously reported that oral administration of allogeneic rat spleen cells before kidney allotransplantation significantly prolongs graft survival. This prolongation was alloantigen specific and was associated with a decrease in graft-infiltrating cells (GIC) and an increase in transcription of IL-4 mRNA in the GIC. In this study increased splenic mixed lymphocyte responses from animals orally exposed to alloantigen before kidney transplantation suggested that the kidney allograft prolongation was not due to a masking of allorecognition, but to an immunomodulation of the immune response. We have assessed GIC T cell subsets on day 5 post-transplant and found decreased numbers of CD4(+) T cells in fed animals compared with controls, but there was no change in CD8(+) T cell numbers. The CD8(+) GIC from fed animals transcribed substantial levels of perforin, granzyme, and Fas ligand mRNA, indicating the presence of active CTL. Direct CTL assays showed that the GIC from fed recipients exhibited higher allo-CTL activity than GIC from control unfed recipients. In addition, the CD8(+) GIC exhibited high levels of IL-4 mRNA, suggesting Tc2-type regulatory cells. Prolonged graft survival in the face of active CTL and Tc2 cells suggests the presence of a CD8(+) regulatory cell population in the allograft. To confirm this, cell transfer experiments were performed. Prolongation of graft survival was transferred from rats orally exposed to alloantigen to naive animals by transfer of CD8(+) GIC. This is the first report that oral exposure to alloantigen prolongs kidney allograft survival by the generation of intragraft CD8(+) regulatory cells.
Immunoliposomal Systems Targeting Primary Effusion Lymphoma: <i>In Vitro</i> Study (2010)

ILp could be proposed as effective carriers for oligonucleotide transfer in BCBL-1 cells. In vitro experimental results encourage us to further test the in vivo therapeutic potential of ILp for specific delivery of antitumoral agents.
Cracking Metal-Contaminated Oils with Catalysts Containing Metal Scavengers (1988)

The addition of layered magnesium silicate particles such as sepiolite to a high activity commercial fluid cracking catalyst (FCC), generates dual-functional cracking catalyst (DFCC) mixtures that, even when metal contaminated with as much as 1.5 wt% vanadium, are capable of retaining useful cracking activity (70% conversion) when cracking a light gas oil (with an API gravity of 29.6) at microactivity test (MAT) conditions. Improved coke and hydrogen selectivity were also observed. Transport experiments have been used to show that the DFCC enhanced vanadium resistance can be attributed to the gas phase transport of this metal from the host catalyst to the diluent (sepiolite) where it is sorbed and passivated.
Pathogenetic importance and therapeutic implications of NF‐κB in lymphoid malignancies (2012)

Derangement of the nuclear factor κB (NF-κB) pathway initiates and/or sustains many types of human cancer. B-cell malignancies are particularly affected by oncogenic mutations, translocations, and copy number alterations affecting key components the NF-κB pathway, most likely owing to the pervasive role of this pathway in normal B cells. These genetic aberrations cause tumors to be 'addicted' to NF-κB, which can be exploited therapeutically. Since each subtype of lymphoid cancer utilizes different mechanisms to activate NF-κB, several different therapeutic strategies are needed to address this pathogenetic heterogeneity. Fortunately, a number of drugs that block signaling cascades leading to NF-κB are in early phase clinical trials, several of which are already showing activity in lymphoid malignancies.
Placebo or panacea? Rural transport corridors: some social and environmental issues (1996)

Travel poverty, defined as access to choice in relation to travel, is faced by those who cannot travel as much as they would like, or who have inadequate local amenities, reducing options about travel. The context for this study is increasing rural car use and by policies which directly or indirectly promote it, damaging the quality of life and the environment and lessening the safety of public space. Presents evidence from a study of two rural villages indicating that the development of public trans- port corridors might, in some circumstances and to some extent, meet sustainability (i.e. environmental, equity and participation) objectives. Also discusses possible limits to the effectiveness and potential disadvantages of developing rural public trans- port corridors. Raises the particular effectiveness of rail corridors in meeting environ- mental objectives.
Respiratory Gating for Radiotherapy: Main Technical Aspects and Clinical Benefits (2013)

Respiratory-gated radiotherapy offers a significant potential for improvement in the irradiation of tumor sites affected by respiratory motion such as lung, breast, and liver tumors. An increased conformality of irradiation fields leading to decreased complication rates of organs at risk is expected. Five main strategies are used to reduce respiratory motion effects: integration of respiratory movements into treatment planning, forced shallow breathing with abdominal compression, breath-hold techniques, respiratory gating techniques, and tracking techniques. Measurements of respiratory movements can be performed either in a representative sample of the general population, or directly on the patient before irradiation. Reduction of breathing motion can be achieved by using either abdominal compression, breath-hold techniques, or respiratory gating techniques. Abdominal compression can be used to reduce diaphragmatic excursions. Breath-hold can be achieved with active techniques, in which airflow of the patient is temporarily blocked by a valve, or passive techniques, in which the patient voluntarily breath-holds. Respiratory gating techniques use external devices to predict the phase of the breathing cycle while the patient breathes freely. Another approach is tumor-tracking technique, which consists of a real-time localization of a constantly moving tumor. This work describes these different strategies and gives an overview of the literature.
Language use in a branching Universe (2005)

I investigate the consequences for semantics, and in particular for the semantics of tense, if time is assumed to have a branching structure not out of metaphysical necessity (to solve some philosophical problem) but just as a contingent physical fact, as is suggested by a currently-popular approach to the interpretation of quantum mechanics. 1
Selective interhalogen etching of tantalum compounds and other semiconductor materials (1985)

We find that gaseous ClF3 is an effective and selective etchant for a variety of transition metals and metal compounds. Kinetics were studied for etching α-Ta (13–16 atom % N), Ta2N, and Ta2O5 in this gas, as a function of temperature and pressure, to provide effective activation energies of 4.0, 4.4, 7.7 kcal/mole, respectively. Relative etch rates measured in CF4/O2 and NF3 plasmas indicate that ClF3 gaseous etching has more than an order of magnitude better selectivity for nonoxidic metal compounds over the corresponding oxide. At 100 °C, selectivity for etching α-Ta or Ta2N over Ta2O5 is more than 160:1. Other materials used in semiconductor manufacture, such as SixNy, W, TaSi2, and photoresist, were also briefly surveyed and the results suggest ClF3 holds promise for isotropic etching applications that require high selectivity.
Gold and iron oxide hybrid nanocomposite materials (2011)

This critical review provides an overview of current research activities that focused on the synthesis and application of multi-functional gold and iron oxide (Au-Fe(x)O(y)) hybrid nanoparticles and nanocomposites. An introduction of synthetic strategies that have been developed for generating Au-Fe(x)O(y) nanocomposites with different nanostructures is presented. Surface functionalisation and bioconjugation of these hybrid nanoparticles and nanocomposites are also reviewed. A variety of applications such as theranostics, gene delivery, biosensing, cell sorting, bio-separation, and catalysis is discussed and highlighted. Finally, future trends and perspectives of these sophisticated nanocomposites are outlined. Underpinning the fundamental requirements for effectively forming Au-Fe(x)O(y) hybrid nanocomposite materials would shed light on future development of nanotheranostics, nanomedicines, and chemical technologies. It would be interesting to investigate such multi-component composite nanomaterials with different novel morphologies in the near future to advance chemistry, biology, medicine, and engineering multi-disciplinary research (120 references).
Parallel IP packet forwarding for tomorrow's IP routers (2002)

The invention and evolution of the dense wavelength division multiplexing (DWDM) technology has brought a breakthrough to high-speed networks, and it has put a lot of pressure on research in the area of IP router to catch up. Besides, with up-coming quality of service (QoS) requirements raised by a wide range of communication-intensive, real-time multimedia applications, the next-generation IP routers should be QoS-capable. Limited by Moore's law, one possible solution is to introduce parallelism as well as the differentiated service (DiffServ) scheme [5, 11] into the router architecture to provide QoS provision at a high speed and a low cost. We propose a novel architecture called the high-performance QoS-capable IP router (HPQR). We address one key design issue in our architecture-the distribution of IP packets to multiple independent routing agents so that the workload at routing agents is balanced and the packet ordering is preserved. We introduce the enhanced hash-based distributing scheme (EHDS) as the solution. Simulations are carried out to study the effectiveness of EHDS. The results show that EHDS does meet our design goals very well.
