An EMI Resisting LIN Driver in 0.35-micron High-Voltage CMOS (2007)

This paper describes the design of a local interconnect network (LIN) integrated output driver circuit exhibiting a high degree of immunity against conducted electromagnetic interference (EMI). The transmitted signal of this driver is shaped with a predefined slope so as to reduce electromagnetic emission at higher frequencies. The effect of EMI coupling from the data bus into the driver circuit is countered using a new feedback scheme which shields the slope shaping function from the output stage. Although the output signal may be heavily corrupted by EMI, the LIN driver continues to deliver an unaltered duty cycle, which is mandatory to obtain an error-free data transmission. Measurements show that this driver circuit manages to withstand the highest levels of the direct power injection (DPI) measurements independently of the injected EMI level.

Uterine leiomyoma and menstrual cycle characteristics in a population-based cohort study (2004)

In this Italian population of women not seeking gynaecological care, menstrual characteristics are not related to leiomyoma.
Electrostatic Effects in Proteins (1978)

Electrostatic effects dominate many aspects of protein behavior. When polypeptide chains fold up, most polar side chains seek the exterior, where they can be solvated. Water bound in the interior has been found between the domains of enzymes of the chymotrypsin family, and between the subunits of hemoglobin and tobacco mosaic virus protein. Assembly of this protein from disk to virus is triggered by electrostatic interactions between neighboring subunits. Lysozyme stabilizes the constellation of charges involved in the transition state of its substrate by both permanent and induced dipoles. All factors that lower the oxygen affinity of hemoglobin act by strengthening the salt bridges that constrain its quaternary deoxy (T) structure. Enzymes of thermophile bacteria owe their extra stability mostly to additional salt bridges. The rate of denaturation of hemoglobins by alkali is determined by the ionization of internal side chains with pK 's of about 12.
Simple and Clean Photoinduced Aromatic Trifluoromethylation Reaction (2016)

We describe a simple, metal- and oxidant-free photochemical strategy for the direct trifluoromethylation of unactivated arenes and heteroarenes under either ultraviolet or visible light irradiation. We demonstrated that photoexcited aliphatic ketones, such as acetone and diacetyl, can be used as promising low-cost radical initiators to generate CF3 radicals from sodium triflinate efficiently. The broad utility of this strategy and its benefit to medicinal chemistry are demonstrated by the direct trifluoromethylation of unprotected bidentate chelating ligand, xanthine alkaloids, nucleosides, and related antiviral drug molecules.

Presentation and analysis of data on radiographic outcome in clinical trials: Experience from the TEMPO study (2005)

We suggest a panel of alternative analysis methods and alternative ways of handling missing information to verify that the radiographic results reported in an randomized controlled trial are not influenced by technical factors, such as interpolation, handling of missing data, and choice of statistical tests.
New access index for fast execution of conjunctive queries over text data (2003)

Complex queries with multiple conjunctive (AND) predicates have attracted increasing attention for their importance in OLAP systems. The signature index is ideal for the fast execution of queries involving multiple conjunctive predicates. However, previous signature-based methods did not separate the signatures from different attributes. We have developed a signature-augmented access index, called an MG-tree. Its main features are: (1) it is a lightweight search tree for indexing multiple attributes of text data, and (2) it eliminates the mix of signatures from different attributes, so the construction and maintenance of the index is easy and searching is efficient. Our analyses and experiments show that the MG-tree achieved a significant improvement in terms of access speed and storage space overhead over both tree-like indexes and previous multi-dimensional signature indexes, and is easier to build and maintain. The MG-tree can be employed in practical DBMS implementations.
Cumulative baby take-home rate among women with PCOS treated by IVF (2010)

Although the baby take-home rate was similar among women with PCOS, and controls, the outcomes of consecutive cycles were not equal. Cumulative data give more realistic information than pooled cycles.
Blue-blocking filters do not alleviate signs and symptoms of digital eye strain (2022)

The B-B filter did not alter OO muscle activity or visual symptomatology significantly during the execution of a 30-min reading task in asymptomatic subjects. These findings support the idea that B-B filters do not attenuate signs and symptoms of digital eye strain.
Small Molecule Therapy for Genetic Disease (2010)

Thoene summarises the substantial work that has been accomplished in the treatment of inborn errors of metabolism with simple molecules. This handbook will enable interested clinician scientists to rapidly survey the field, thus ascertaining what has been done as well as future directions for therapeutic research. Its important introductory chapters discuss the infrastructure of the field. The book closely analyses the cofactors used to augment the function of defective enzymes and the compounds that are able to utilise an alternative pathway in order to avoid the consequences of the metabolic block present in the patient. Among other therapies, the authors discuss the use of zinc and tetrathiomolybdate to treat Wilson's disease and the use of cysteamine to treat nephropathic cystinosis.
Proposed laser-induced fluorescence method for remote thermometry inturbine engines (1986)

Introduction R is under way to measure the temperature of surfaces within operating turbine engines. To supply these measurements, which are necessary for some Air Force programs, current efforts are concentrating on the first-stage rotor blades and stator vanes. These components, positioned just behind the burner, are the most difficult parts of a turbine to measure because they are the hottest and because the leading surfaces of the firststage vanes reflect intense background blackbody radiation from the burning fuel. Currently, the two principal temperature-diagnostic tools are pyrometers and thermocouples. Contact sensors, such as thermocouples, require leads that connect them to datarecording instruments, while optical sensors, such as pyrometers, are remote (noncontact) electric thermometers. Both thermocouples and pyrometers exhibit limitations in turbine-engine applications. Protruding surface-mounted wire thermocouples, which disturb the airflow and heat-transfer characteristics, perturb the temperature at the point being measured. Cutting trenches to flush-mount them changes the structural properties and also perturbs the temperature. Thin-film thermocouples are so small and flat that their influence on temperature is negligible, but they do not adhere well under operating conditions. They also erode and oxidize and are expensive to install. Because they lack a way of scanning, pyrometers can look at only one point in any given experiment geometry and are therefore not suitable for measuring static surfaces. In addition, pyrometers give erroneous readings in the presence of intense background radiation, and their low-temperature limit of about 700°C makes them useful only in hot regions of engines. Both gas centrifuges and turbine engines have hostile internal environments when operating. For our purposes, the principal difference is that the engine runs at high temperatures,
An efficient variable length coding scheme for an IID source (2002)

In this article we examine a scheme that uses two alternating Huffman codes to encode a discrete independent and identically distributed source with a dominant symbol. One Huffman code encodes the length of runs of the dominant symbol, the other encodes the remaining symbols. We call this combined strategy alternating runlength Huffman (ARH) coding. This is a popular scheme, used for example in the efficient pyramid image coder (EPIC) subband coding algorithm. Since the runlengths of the dominant symbol are geometrically distributed, they can be encoded using the Huffman codes identified by Golomb (1966) and later generalized by Gallager and Van Voorhis (1975). This runlength encoding allows the most likely symbol to be encoded using less than one bit per sample, providing a simple method for overcoming a drawback of prefix codes-that the redundancy approaches one as the largest symbol probability P approaches one. For ARH coding, the redundancy approaches zero as P approaches one. Comparing the average code rate of ARH with direct Huffman coding we find that: 1. If P<1/3, ARH is less efficient than Huffman coding. 2. If 1/3/spl les/P<2/5, ARH is less than or equally efficient as Huffman coding, depending on the source distribution. 3. If 2/5/spl les/P/spl les/0.618, ARH and Huffman coding are equally efficient. 4. If P>0.618, ARH is more efficient than Huffman coding. We give examples of applying ARH coding to some specific sources.
Hybrid plasmonic magnetic nanoparticles as molecular specific agents for MRI/optical imaging and photothermal therapy of cancer cells (2007)

Nanoparticles which consist of a plasmonic layer and an iron oxide moiety could provide a promising platform for development of multimodal imaging and therapy approaches in future medicine. However, the feasibility of this platform has yet to be fully explored. In this study we demonstrated the use of gold-coated iron oxide hybrid nanoparticles for combined molecular specific MRI/optical imaging and photothermal therapy of cancer cells. The gold layer exhibits a surface plasmon resonance that provides optical contrast due to light scattering in the visible region and also presents a convenient surface for conjugating targeting moieties, while the iron oxide cores give strong T2 (spin–spin relaxation time) contrast. The strong optical absorption of the plasmonic gold layer also makes these nanoparticles a promising agent for photothermal therapy. We synthesized hybrid nanoparticles which specifically target epidermal growth factor receptor (EGFR), a common biomarker for many epithelial cancers. We demonstrated molecular specific MRI and optical imaging in MDA-MB-468 breast cancer cells. Furthermore, we showed that receptor-mediated aggregation of anti-EGFR hybrid nanoparticles allows selective destruction of highly proliferative cancer cells using a nanosecond pulsed laser at 700 nm wavelength, a significant shift from the peak absorbance of isolated hybrid nanoparticles at 532 nm.
DNA breakdown by the 4-quinolones and its significance (1990)

DNA breakdown occurred in Escherichia coli KL16 exposed to nalidixic acid, ciprofloxacin or norfloxacin. However DNA breakdown does not seem to be the cause of the lethality of the 4-quinolones because it still occurred under conditions which abolished the lethality of nalidixic acid. Furthermore, no correlation was found between the amount of DNA breakdown and the rate of death of bacteria caused by the three 4-quinolones. Similarly, DNA breakdown did not occur when recB or recC mutants were treated with nalidixic acid despite both mutants being killed by the drug, again suggesting that DNA breakdown is not the cause of bacterial death. Since recB and recC mutants lack exonuclease V, this enzyme may be responsible for the DNA breakdown observed in bacteria treated with 4-quinolones.

Implications of the invariant <i>gamma</i>-chain on the intracellular transport of class II histocompatibility antigens. (1985)

Abstract We have examined the role of the invariant gamma-chain on the intracellular transport of human class II histocompatibility antigens. mRNA was selected by hybridization to cDNA corresponding to class II alpha-, beta-, and gamma-chains, and the obtained mRNA fractions were injected individually and in various combinations into X. laevis oocytes. Translation products were isolated after various periods of chase, and their carbohydrate moieties were analyzed to monitor the subcellular localization of polypeptide chains. A mixture of alpha-, beta-, and gamma-chains, or gamma-chains alone, were transported and glycosylated to the same extent as in a B lymphoblastoid cell line. However, although alpha- and beta-chains formed a complex in the absence of the gamma-chain, the transport of this complex was slowed down. Furthermore, the glycosylation of alpha- and beta-chains appeared incomplete. Thus, the invariant gamma-chain seems to play a crucial role for the rate of transport and glycosylation of class II alpha- and beta-chains.
A delay sensitive LTE uplink packet scheduler for M2M traffic (2013)

Some M2M applications such as those found in a Smart Grid environment generate event driven and delay sensitive uplink traffic. Wide area cellular systems such as LTE are usually not optimized for such traffic. In this paper, we design an LTE scheduler with the main objective of maximizing the percentage of uplink packets that satisfy their individual delay budgets. In order to do this accurately, we allow devices to notify the eNodeB of the age of the oldest packet in their buffers via a new MAC control element in the uplink MPDU. This information is used by the eNodeB to calculate an absolute deadline for each packet request individually, and the eNodeB scheduler ranks requests according to an urgency metric that depends upon the time remaining to the deadline and other factors such as the volume of pending data in the device buffers. Using an OPNET simulation model of an LTE TDD system, we show that our proposed scheduler can satisfy the uplink delay budget for more than 99% of packets for bursty delay sensitive M2M traffic even when the system is fully loaded with regard to the data channel utilization.
Folded shift multiplexing (2003)

Shift multiplexing is a holographic recording method that uses a spherical reference wave. We extend the principle to a thin slab of holographic material that acts as a waveguide. Total internal reflection folds the reference spherical beam in one dimension. We demonstrate that the shift selectivity with the folded spherical beam is independent of the slab thickness but depends instead on the numerical aperture of the coupled spherical wave. A shift selectivity of 0.5 microm has been achieved with a 1-mm-thick LiNbO3 crystal and 50 high-definition data pages are recorded with this method.
Design of low-density parity-check codes for bandwidth efficient modulation (2002)

We design low-density parity-check (LDPC) codes for bandwidth efficient modulation using a multilevel coding (MLC) technique. We develop a method to analyze the asymptotic performance of the LDPC codes using message-passing decoding at each level of the MLC scheme as the codeword length goes to infinity. Simulation of very large block size LDPC codes verifies the accuracy of the analytical results. We jointly optimize the code rates and code parameters of the LDPC codes at each level of the MLC scheme, and the asymptotic performance of the optimized irregular LDPC codes is very close to the channel capacity of the additive white Gaussian noise (AWGN) channel.

Outbreaks of Salmonella enteritidis Infections in the United States, 1985-1991 (1994)

The spread of Salmonella enteritidis infections in the United States was tracked to identify potential risk factors and preventive measures. Isolation rates and information regarding outbreaks of S. enteritidis from 1985 through 1991 were determined by reports to the national Salmonella surveillance system and through the foodborne disease outbreak surveillance system. From 1985 through 1991, 380 outbreaks were reported involving 13,056 ill persons and 50 deaths. The proportion of Northeast outbreaks fell from 81% in 1985 to 55% in 1991 as the number of outbreaks in other areas increased. Grade A shell eggs were implicated in 82% of outbreaks. Case-fatality rates in nursing homes and hospitals were 70 times higher than in other settings. Cultures of environmental or animal specimens from all farms tested yielded S. enteritidis. Eggborne S. enteritidis infections are a major public health problem. Preventive measures, including educating consumers about proper handling of eggs, using pasteurized eggs, and controlling infections on egg farms, may stem the impact of this disease.
A novel hybrid excitation flux switching synchronous machine for a high-speed hybrid electric vehicle applications (2011)

Hybrid excitation machines (HEMs) that consist of permanent magnet (PM) and field excitation coil (FEC) as their main flux sources has several attractive features compared to interior permanent magnet synchronous machines (IPMSM) conventionally employed in hybrid electric vehicles (HEVs). Among various types of HEM, the machine with both permanent magnet and field excitation coil located on the stator has the advantage of robust rotor structure similar as switch reluctance machine (SRM). In addition, the variable flux control capabilities from field excitation coil make this machine becoming more attractive to be applied for high-speed motor drive systems, coupled with reduction gear. This HEM can be categorized as hybrid excitation flux switching synchronous machine (HEFSSM). In this paper, a novel 12Slot-10Pole HEFSSM where the field excitation coil is wounded in radial direction in the stator is proposed for traction drives in HEVs. The design target of the proposed machine is a maximum torque of 210Nm with reduction gear ratio of 4:1, a maximum power of 123kW, a maximum power density more than 3.5kW/kg, and a maximum speed of 20,000r/min with similar restrictions and specifications in IPMSM used for LEXUS RX400h. The deterministic design optimization method based on 2D-FEA is used to treat design parameters defined in rotor, armature coil slot and field excitation coil slot until the target performances are achieved, under maximum current density condition for both armature coil and field excitation coil. The final results show that the final design HEFSSM is able to keep the same torque density in existing IPMSM installed on a commercial SUV-HEV.
A Modification for X-Ray Diffraction Topography of Oscillating Method Using Monochromatic Divergent Beams (1974)

A new technique for the oscillation method using monochromatic divergent beams (the O.M.D. method) is proposed for obtaining an undistorted image of X-ray diffraction topograph. In taking topographs over a wide region of the specimen, the specimen and the photographic plate are oscillated around the same rotating axis in the usual O.M.D. method, while they are rotated around two parallel rotating axes in the present method. The rotation speeds of the specimen and the photographic plate are the same in both methods. An application of the new technique to a single crystal of NaCl is presented.
Optimal Scheduling for Charging and Discharging of Electric Vehicles (2012)

The vehicle electrification will have a significant impact on the power grid due to the increase in electricity consumption. It is important to perform intelligent scheduling for charging and discharging of electric vehicles (EVs). However, there are two major challenges in the scheduling problem. First, it is challenging to find the globally optimal scheduling solution which can minimize the total cost. Second, it is difficult to find a distributed scheduling scheme which can handle a large population and the random arrivals of the EVs. In this paper, we propose a globally optimal scheduling scheme and a locally optimal scheduling scheme for EV charging and discharging. We first formulate a global scheduling optimization problem, in which the charging powers are optimized to minimize the total cost of all EVs which perform charging and discharging during the day. The globally optimal solution provides the globally minimal total cost. However, the globally optimal scheduling scheme is impractical since it requires the information on the future base loads and the arrival times and the charging periods of the EVs that will arrive in the future time of the day. To develop a practical scheduling scheme, we then formulate a local scheduling optimization problem, which aims to minimize the total cost of the EVs in the current ongoing EV set in the local group. The locally optimal scheduling scheme is not only scalable to a large EV population but also resilient to the dynamic EV arrivals. Through simulations, we demonstrate that the locally optimal scheduling scheme can achieve a close performance compared to the globally optimal scheduling scheme.
