Acute consumption of fish oil improves postprandial VLDL profiles in healthy men aged 50–65 years (2009)

Dietary supplementation with fish oil induces beneficial changes in the size and concentration of plasma lipoproteins, although the underlying mechanism is unclear. We have investigated the effect of increasing the amount of fish oil in a single meal on the size and concentration of VLDL, LDL and HDL particles during the postprandial period. Healthy men aged 58 (sd 5) years (n 11) consumed isoenergetic, mixed macronutrient test meals containing either 0.3 g (reference, REF) or 2.2 g (high fish oil, HFO) fish oil in a randomised order, and blood samples were collected over the following 6 h. Plasma lipoprotein size and concentration were measured by NMR spectroscopy. There was a significant interaction effect of time and meal composition on the VLDL, but not on the LDL or HDL, concentration (P = 0.036) and particle size (P = 0.005). Consuming the HFO meal significantly increased the VLDL concentration (P < 0.05) and reduced VLDL particle size (P < 0.05) when compared with the REF meal and baseline. LDL particle size decreased slightly during the postprandial period, but there was no difference between the meals. There was no effect of time or meal composition in the LDL concentration. The HDL concentration decreased and size increased slightly during the postprandial period, but there were no significant differences between the meals. Increased consumption of fish oil induces acute changes in the VLDL, but not in the LDL or HDL, metabolism.
Green Tea Polyphenols and Cancer Chemoprevention: Multiple Mechanisms and Endpoints for Phase II Trials (2004)

Among the numerous polyphenols isolated from green tea, the catechin EGCG predominates and is the target of anticancer research. But studies suggest that EGCG and other catechins are poorly absorbed and undergo substantial biotransformation to species that include glucuronides, sulfates, and methylated compounds. Numerous studies relate the antioxidant properties of the catechins with anticancer effects, but recent research proposes other mechanisms of action, including those involving methyl transfers that are subject to allelic variability in the enzyme catechol O-methyl transferase. However, preclinical research is promising and EGCG appears to be ready for further study in phase II and III trials.

Theory of thermoelectric power factor in quantum well and quantum wire superlattices (2001)

Calculations are presented for thermoelectric transport in quantum well and quantum wire superlattices, using (i), the full superlattice electronic band structure in (ii) a multisubband inelastic Boltzmann equation for carrier-phonon scattering. The transport direction is taken to be in the quantum well planes and along quantum wires. It is demonstrated that these two features are needed to give a quantitative treatment of the power factor P in superlattice systems. Results are given for PbTe and for GaAs quantum well and quantum wire superlattices, including the dependence of P on growth direction and on potential offset. For both quantum well and quantum wire superlattices, the dependence of P on potential offset ${V}_{0}$ is found to be qualitatively weaker than in previous work based on the constant relaxation time approximation for carrier scattering. These weaker dependences on ${V}_{0}$ are traced mainly to the enhancement of the electron-phonon scattering rates upon confinement. These results give a different picture of the effects of confinement on P suggesting, for example, that increased confinement in superlattices does not lead to significantly higher P and that free-standing structures, such as free-standing quantum wires, may be particularly attractive for thermoelectric applications.
Required and Received SNRs in Coded Modulation (2020)

Coded modulation techniques aim at reducing the required signal-to-noise ratio (SNR) over the Gaussian channel with an average energy constraint; however, such techniques tend to degrade the received SNR. We studied the balance of required and received SNRs for a realistic system design.
Effects of the lunar environment on space vehicle surfaces (2010)

On the lunar surface there exists very localized and weak magnetic fields, leaving its surface essentially directly exposed to the impact of solar UV and X-rays as well as solar wind plasma and energetic particles. The lack of atmosphere results in a lunar environment charging positive in sunlight and negative in shadow regions resulting in potentials that can vary over orders of magnitude in response to changing solar illumination and plasma conditions. At the macro-scale, contaminant adhesion due to van der Waals' forces are very small and can be easily perturbed by other external forces. However, at the nano-scale, van der Waals forces can be significant. Lunar regolith or dust contamination is a serious problem for equipment and vehicles for space mission applications. Dust contamination gathers on photonic sensors inhibiting motion and data gathering. In addition, devices that require transparency to light for maximum efficiency such as solar photovoltaic power systems, video cameras and optical or infrared detectors will suffer from the dust accumulation. The electrostatic charging of the lunar surface is caused by its interaction with the local plasma environment and solar UV and X-rays induced photoemission of electrons. The lunar thermal environment poses unique challenges to vehicle and sensor surfaces since it is characterized by large temperature variations, long hot and cold soak times, and reduced heat rejection capability due to the presence of the lunar regolith. Fundamental forces (van der Waals) that allow certain contamination to adhere to critical surfaces and methods are being tailored to make these surfaces suitable for this harsh environment.

A downlink/uplink identification algorithm for TDD communication systems in cognitive radio content (2011)

Cognitive radio has been considered as the most possibly techniques to solve the problems of spectrum underutilization and the spectrum scarcity. To discover the spectrum utilization correctly and quickly, the primary signals are sensed and analyzed by the secondary system with no cooperation from primary system. When the primary system is a communication system, downlink and uplink of the primary system should be distinguished by the cognitive radio since different links have different spectrum access opportunities due to the different transmitters should be sensed and the different receivers should be protected by the secondary system. Thus, the downlink/uplink identification is the first step for secondary access. Especially in TDD communication systems, the link identification meets tough demanding of timing and accuracy. In this paper, we proposed a link identification algorithm for TDD communication systems exploiting the power level features of downlink and uplink. Via the energy detection results of a number of distributed secondary users participating in the identification process, secondary system makes the decision about the current link is downlink or uplink. The effects of the local detection and the coverage of the secondary system on the algorithm performance are also analyzed. The results of the simulation show that, even in the toughest situation where the received downlink signal by SS is the lowest and the received uplink signal is the highest, the proposed algorithm can make the identification with high accuracy in a very short detection time.

The influence of coupler geometry on polarization splitting and spectral selectivity is investigated. A selective fused coupler has been made that exhibits a channel separation of Deltalambda = 0.6 nm, an insertion loss of 1 dB, and an extinction ratio of 20 dB. Polarization selectivity of 20 dB has also been achieved.
Development of a microwave radiative transfer simulation tool for the NPOESS program (1998)

The National Polar-orbiting Operational Environmental Satellite System (NPOESS) is the converged weather satellite program for the US Department of Defense and the National Oceanic and Atmospheric Administration (NOAA). NPOESS will provide significant improvements in meteorological and related measurement capabilities in comparison to current operational polar orbiting weather satellites. The availability of the first NPOESS satellite is estimated to be about 2007. In support of the NPOESS program, the authors are developing a Microwave Radiative Transfer Modeling and Simulation Tool, MRT Sim. This paper is an overview of this tool. MRT Sim is written primarily in Python with selected portions in IDL, C and Fortran. The software architecture and design are presented including the user interface, input/output data structure, and specific implementation on a Unix workstation. The physical basis of the models and radiative transfer engine are discussed The tool has a user-friendly, widget-based interface, a modular and extensible design, and cross platform portability.

The proposed approach has been applied to four motors in varied range of power. Dynamic analysis of a three-phases induction motor is studied and the machine dynamics are presented by a set of time-varying differential equations. The analysis and simulation of the mentioned method are shown and comparison of results has been done. The obtained shows that there is a significant difference between dynamic behaviour of low power and high power simulated machines.
Structure and properties of shape‐memory polyurethane block copolymers (1996)

Segmented polyurethanes containing soft segments with lower molecular weight exhibit shape-memorizing properties. Structure and properties of shape-memorizing polyurethanes (S-PUs) were studied. S-PUs are characterized by a rather high glass transition temperature: Tg of S-PUs is usually in the range of 10–50°C. A Pplot of 1/Tm against–In XA is approximately linear, indicating that the hard segments are randomly distributed along the molecular chain. S-PUs with a hard segment of 67–80 mole % form negative spheruiites; they give a faint scattering maximum in a small-angle X-ray diffraction pattern. On the other hand, S-PUs with a hard segment of 50 mole % form fine birefringent elements, giving diffuse scattering in its SAXD pattern. A cyclic test of an S-PUs above Tg indicates that the residual strain increases and the recovery strain decreases with increasing cycle and maximum strain. It has been suggested by dynamic mechanical investigation that the shape-memorizing property of the S-PUs may be ascribed to the molecular motion of the amorphous soft segments. © 1996 John Wiley & Sons, Inc.

A Rapid Method for the Determination of Isolated Trans Isomers in Fats and Oils by IR Spectrophotometric Method (1976)

The trans isomers present in fats and oils can be determined by the rapid liquid-film method from measurements of the infrared absorption at two wavelengths, one due to trans conformation of the double bond and the other due to ester group. The ratio of the two absorbances has a linear relationship with the trans isomer content. This method thus provides a simple determination of trans isomer without weighing in accuracy or messing up an exact volume.
The evolution of air resonance power efficiency in the violin and its ancestors (2015)

The fact that acoustic radiation from a violin at air-cavity resonance is monopolar and can be determined by pure volume change is used to help explain related aspects of violin design evolution. By determining the acoustic conductance of arbitrarily shaped sound holes, it is found that air flow at the perimeter rather than the broader sound-hole area dominates acoustic conductance, and coupling between compressible air within the violin and its elastic structure lowers the Helmholtz resonance frequency from that found for a corresponding rigid instrument by roughly a semitone. As a result of the former, it is found that as sound-hole geometry of the violin's ancestors slowly evolved over centuries from simple circles to complex f-holes, the ratio of inefficient, acoustically inactive to total sound-hole area was decimated, roughly doubling air-resonance power efficiency. F-hole length then slowly increased by roughly 30% across two centuries in the renowned workshops of Amati, Stradivari and Guarneri, favouring instruments with higher air-resonance power, through a corresponding power increase of roughly 60%. By evolution-rate analysis, these changes are found to be consistent with mutations arising within the range of accidental replication fluctuations from craftsmanship limitations with subsequent selection favouring instruments with higher air-resonance power.
Perturbations to lysyl oxidase expression broadly influence the transcriptome of lung fibroblasts (2017)

Lysyl oxidases are credited with pathogenic roles in lung diseases, including cancer, fibrosis, pulmonary hypertension, congenital diaphragmatic hernia, and bronchopulmonary dysplasia (BPD). Lysyl oxidases facilitate the covalent intra- and intermolecular cross-linking of collagen and elastin fibers, thereby imparting tensile strength to the extracellular matrix (ECM). Alternative ECM-independent roles have recently been proposed for lysyl oxidases, including regulation of growth factor signaling, chromatin remodeling, and transcriptional regulation, all of which impact cell phenotype. We demonstrate here that three of the five lysyl oxidase family members, <i>Lox</i>, <i>Loxl1</i>, and <i>Loxl2</i>, are highly expressed in primary mouse lung fibroblasts compared with other constituent cell types of the lung. Microarray analyses revealed that small interfering RNA knockdown of <i>Lox</i>, <i>Loxl1</i>, and <i>Loxl2</i> was associated with apparent changes in the expression of 134, 3,761, and 3,554 genes, respectively, in primary mouse lung fibroblasts. The impact of lysyl oxidase expression on steady-state <i>Mmp3</i>, <i>Mmp9</i>, <i>Eln</i>, <i>Rarres1</i>, <i>Gdf10</i>, <i>Ifnb1</i>, <i>Csf2</i>, and <i>Cxcl9</i> mRNA levels was validated, which is interesting, since the corresponding gene products are relevant to lung development and BPD, where lysyl oxidases play a functional role. In vivo, the expression of these genes broadly correlated with <i>Lox</i>, <i>Loxl1</i>, and <i>Loxl2</i> expression in a mouse model of BPD. Furthermore, β-aminopropionitrile (BAPN), a selective lysyl oxidase inhibitor, did not affect the steady-state mRNA levels of lysyl oxidase target genes, in vitro in lung fibroblasts or in vivo in BAPN-treated mice. This study is the first to report that lysyl oxidases broadly influence the cell transcriptome.

Efficient Simulation of hybrid stripmap/spotlight SAR raw signals from extended scenes (2004)

The hybrid stripmap/spotlight mode for a synthetic aperture radar (SAR) system is able to generate microwave images with an azimuth resolution better than the one achieved in the stripmap mode and a ground coverage better than the one of the spotlight mode. In this paper, time- and frequency-domain-based procedures to simulate the raw signal in the hybrid stripmap/spotlight mode are presented and compared. We show that a two-dimensional Fourier domain approach, although highly desirable for its efficiency, is not viable. Accordingly, we propose a one-dimensional (1-D) range Fourier domain approach, followed by 1-D azimuth time-domain integration. This method is much more efficient than the time-domain one, so that extended scenes can be considered. In addition, it involves approximations usually acceptable in actual cases. Effectiveness of the simulation scheme is assessed by using numerical examples.
Restaurant search with predictive multispace queries (2015)

This paper describes a web-based search application used for locating restaurants in a multidimensional content space via interactive space visualization. The primary goal of our research is to reduce the cognitive complexity of query selection, as well as to help the user avoid one of the common pitfalls of traditional search mechanisms: retrieving too many or too few results. Our method approaches this problem by continuously staying one step ahead of the user, constructing a graphical output to summarize how further query adjustments will impact subsequent search results. In actively precomputing queries ahead of the user we help them avoid the trial-and-error search process often associated with trying to find something in an unfamiliar, opaque database. We combine our visual search method with a profile-based knowledge system which helps users find restaurants accessed by people with similar interests.

An effcient induction motor drive method with a regenerative power storage system driven by an optimal torque (2008)

When the motor speed is reduced by using a regenerative brake, the mechanical energy of rotation can be converted to the regenerative electric energy. In order to improve the efficiency of the motor drive systems, the regenerative power is charged and discharged by power storage systems (PSS). Moreover, optimal regenerative and acceleration torque of the motor should be discussed in order to maximize the regenerative electric energy and to minimize the required energy for acceleration. This paper presents an effective robust control method of a regenerative power storage system (PSS) and a design methodology of an optimal acceleration torque in order to achieve an efficient induction motor drive system. The PSS, treated in this paper, consists of an electrolytic capacitor and a bi-directional DC-DC chopper. At first, it will be shown that the PSS can be represented by a quite general second order differential equation. For this model, a robust control method will be proposed. Secondary, an optimal acceleration torque will be derived by means of variational method. The effectiveness of the proposed methods are illustrated by some simulations and experiments.

Phasic excitation of dopamine neurons in ventral VTA by noxious stimuli (2009)

Midbrain dopamine neurons play central roles in reward processing. It is widely assumed that all dopamine neurons encode the same information. Some evidence, however, suggests functional differences between subgroups of dopamine neurons, particularly with respect to processing nonrewarding, aversive stimuli. To directly test this possibility, we recorded from and juxtacellularly labeled individual ventral tegmental area (VTA) dopamine neurons in anesthetized rats so that we could link precise anatomical position and neurochemical identity with coding for noxious stimuli. Here, we show that dopamine neurons in the dorsal VTA are inhibited by noxious footshocks, consistent with their role in reward processing. In contrast, we find that dopamine neurons in the ventral VTA are phasically excited by footshocks. This observation can explain a number of previously confusing findings that suggested a role for dopamine in processing both rewarding and aversive events. Taken together, our results indicate that there are 2 functionally and anatomically distinct VTA dopamine systems.
