Performance Analysis of DC-DC Converter and DTC Based Fuzzy Logic Control for Power Management in Electric Vehicle Application (2020)

The aim of this paper is the developments a DC/DC boost converter use to powered a DC/AC inverter with induction motor. A strategy of control of an induction motor (IM) used as a propulsion system of an electric vehicle (EV). The boost converter ensures an energy flux for an ideal operation of the vehicle even in case of battery voltage drop. The technique proposed is based on a direct flow and torque control diagram (DTC) and also introduces the fuzzy logic control (FLC) as well as the regulator in the place of a conventional PI regulator. The proposed approach covers the vehicle's torque demand and it optimizes the training performance. Simulation results on a test vehicle propelled by 38-kW induction motor showed that the proposed control approach operates satisfactorily. The analysis and simulations lead to the conclusion that the proposed system is feasible and can be tested on experimental bench.
Effects of polyamines on intracellular calcium and mechanical activity in smooth muscle of guinea‐pig taenia coli (1993)

The effects of the polyamines putrescine, spermidine and spermine on the mechanical activity in smooth muscle from guinea-pig taenia coli were investigated. Tissue concentrations of spermidine and spermine were about 240 and 160 nmol g-1, respectively, while the putrescine concentration was much lower (4 nmol g-1). Intracellular [Ca2+] was determined using the Fura-2 method and the effects of extracellularly applied polyamines were observed. Spermine (10(-5)-10(-3) mol l-1) dose-dependently inhibited spontaneous contractions as well as contractions induced by 20-25 mmol l-1 KCl, with 10(-3) mol l-1 spermine giving nearly total relaxation. Spermidine (10(-3) mol l-1) relaxed a 20 mmol l-1 KCl contracture, while putrescine had no effect. A decrease in intracellular [Ca2+] accompanied the relaxation induced by spermine. In contrast to the effects on spontaneous activity and intermediate [KCl], both the contraction and the accompanying increase in intracellular [Ca2+] induced by 90-120 mmol l-1 KCl were unaffected by spermine. Spermine did not affect the maximal Ca(2+)-induced force of chemically skinned taenia coli preparations, but a small potentiating effect on the Ca2+ sensitivity was observed. The results indicate that the relaxation induced by spermine depends on an intact cell membrane. Furthermore, the relaxing effect is due to decreased intracellular [Ca2+] and seems to occur only when the contraction is elicited by repetitive action potentials, and not by sustained depolarization.
Lift-off and hybrid applications with ma-n 1405 negative-tone resist (2009)

The authors evaluated the performance of the negative-tone resist ma-n 1405 for lift-off and hybrid processes by combining electron-beam and/or laser lithography techniques with metal deposition. Electron lithography and gold deposition allow the fabrication of useful structures such as circles, lines, and coaxes with a resolution of nearly 70nm. The ability of this resist to withstand a hybrid process was also tested. A constricted line was transferred to the silicon substrate by lift-off, where the large (1μm linewidth) and the small (200nm linewidth) features were, respectively, patterned by laser and electron-beam direct writing on a single resist level.
Control of Conformational Flexibility in Calix[6]Arenes: Synthesis and Characterisation of Triply Bridged Calix[6]Arene–-10,15-Dihydro-5H-Tribenzo [a,d,g]Cyclononene Conjugates (2008)

A series of triply bridged symmetrical tert-butylcalix[6]arene–-10,15-dihydro-5 H-tribenzo[ a,d,g]cyclononene conjugates have been synthesised in excellent yields. It has been observed that the synthesised multi-cavity molecular receptors retain the calix[6]arene and derivatised 10,15-dihydro-5 H-tribenzo[ a,d,g]cyclononene units in their cone conformations in solution. While the employed alkyl spacers confer flexibility to the conjugate units at room temperature, the synthesised receptors have been observed to exist in flattened cone conformations at low temperatures as determined by variable temperature NMR measurements. It has been observed that 6b shows a significant selectivity towards Ba 2+ over other metal ions while compound 6c shows selectivity towards NH 4 + ions from amongst alkali, alkaline-earth and transition metal picrates. Alkali and transition metal ions are poorly extracted by the hosts 6a–c. The extraction abilities of host molecules 5a–c towards metal picrates were found to be much less than that of 6a–c.
The Portable Chemical Sterilizer (PCS), D-FENS, and D-FEND ALL: Novel Chlorine Dioxide Decontamination Technologies for the Military (2014)

There is a stated Army need for a field-portable, non-steam sterilizer technology that can be used by Forward Surgical Teams, Dental Companies, Veterinary Service Support Detachments, Combat Support Hospitals, and Area Medical Laboratories to sterilize surgical instruments and to sterilize pathological specimens prior to disposal in operating rooms, emergency treatment areas, and intensive care units. The following ensemble of novel, 'clean and green' chlorine dioxide technologies are versatile and flexible to adapt to meet a number of critical military needs for decontamination(6,15). Specifically, the Portable Chemical Sterilizer (PCS) was invented to meet urgent battlefield needs and close critical capability gaps for energy-independence, lightweight portability, rapid mobility, and rugged durability in high intensity forward deployments(3). As a revolutionary technological breakthrough in surgical sterilization technology, the PCS is a Modern Field Autoclave that relies on on-site, point-of-use, at-will generation of chlorine dioxide instead of steam. Two (2) PCS units sterilize 4 surgical trays in 1 hr, which is the equivalent throughput of one large steam autoclave (nicknamed "Bertha" in deployments because of its cumbersome size, bulky dimensions, and weight). However, the PCS operates using 100% less electricity (0 vs. 9 kW) and 98% less water (10 vs. 640 oz.), significantly reduces weight by 95% (20 vs. 450 lbs, a 4-man lift) and cube by 96% (2.1 vs. 60.2 ft(3)), and virtually eliminates the difficult challenges in forward deployments of repairs and maintaining reliable operation, lifting and transporting, and electrical power required for steam autoclaves.

Progestational Activity of Natural and Synthetic Androgens (1978)

Uteroglobin, a progesterone‐regulated secretory protein in rabbit uterus, was used as a marker protein for studies on progestational activity of various natural and synthetic androgens. All the androgens investigated were able to induce uteroglobin synthesis in rabbit uterus; some of the synthetic androgens were even better inducers than progesterone itself. Our results suggest that androgens elicit their regulatory action on uteroglobin synthesis by way of progestin receptor mechanism, since: (i) There was an intimate correlation between the in vitro binding affinity to progestin receptor and the in vivo potency of the androgens to induce uteroglobin synthesis; (ii) Androgens were able to translocate cytosol progestin receptors to uterine nuclei; (iii) Dose‐response curves for uteroglobin induction were parallel for androgens and progestins, and (iv) Flutamide, a non‐steroidal antiandrogen, did not abolish androgen‐induced synthesis of uteroglobin or androgen‐promoted nuclear translocation of cytosol progestin receptors. Both progesterone and androgens seem to control uteroglobin synthesis through mechanisms involving formation of new mRNA species, since in each case there was an increase in the uterine preuteroglobin‐mRNA activity, as evaluated by a cell‐free in vitro translation assay, which correlated with the amount of uteroglobin secreted into the uterine fluid. Some of the androgens studied (7α, 17α‐dimethyl‐19‐nortestosterone, 17α‐ethyl‐19‐nortestosterone and 11‐methylene‐17α‐methyl‐19‐nortestosterone) enhanced uteroglobin synthesis to the same or greater extent than progesterone. Interestingly, these steroids are also known to be very potent androgens. The progestational actions of androgens may be applicable to human tissues, too, since all the androgens investigated were bound by the human uterine progestin receptor in a fashion identical with the rabbit receptor.
A new clinical scintillation camera with pulse tail extrapolation electronics (1990)

The performance of a novel scintillation camera, designed for high-event-rate capability was evaluated. The system consisted of a 400-mm field-of-view NaI(Tl) camera with 61 photomultiplier tubes and modified General Electric Starcam electronics. A significant feature of the system was circuitry for performing pulse tail extrapolation and separation of individual pulses involved in pulse pile-up events. System deadtime, flood field uniformity, energy resolution, linearity, spatial resolution bar phantom image quality, and misplaced events were evaluated for count rates up to 200 kcps in a 20% photopeak window. Results indicate that this camera design does not compromise image quality at normal clinical count rates and that at higher event rates, it can provide better image quality and increased sensitivity over many Anger cameras employed in nuclear medicine.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Compressed Natural Gas (CNG) Fleets in Southern California: Variations in Vehicles and Route Types (2015)

A number of vehicle fleets around the world have transitioned to compressed natural gas (CNG), but public refueling stations remains sparse away from fleet depots. Given the varied vehicle and route types of fleets, empirical data on their use of public refueling stations is important to understand, because like consumers, fleet drivers face range anxiety and their driving and refueling habits inform key assumptions important to station location. The authors surveyed 127 drivers of CNG fleet vehicles in Los Angeles at six stations across the metropolitan area. The key survey questions concerned the stops immediately before and after refueling, habituality of refueling away from base and fuel tank levels before refueling. The authors demonstrate that regardless of fleet or vehicle type, drivers deviate up to six minutes in order to refuel, and they also do not exhibit significant differences in fuel tank levels at the time of refueling. The authors also observe that 35% of fleet drivers surveyed indicated they were solely reliant upon away-from-base refueling for their operations, but there is variation between vehicle types. These findings demonstrate that fleet drivers do consider station locations away from their base when refueling, and they also indicate that assumptions made within facility location models with respect to fuel tank level and deviation thresholds do not necessarily have to consider the differences in vehicle or route type when employed at a metropolitan or regional scale.
Universal structural parameter to quantitatively predict metallic glass properties (2016)

Quantitatively correlating the amorphous structure in metallic glasses (MGs) with their physical properties has been a long-sought goal. Here we introduce 'flexibility volume' as a universal indicator, to bridge the structural state the MG is in with its properties, on both atomic and macroscopic levels. The flexibility volume combines static atomic volume with dynamics information via atomic vibrations that probe local configurational space and interaction between neighbouring atoms. We demonstrate that flexibility volume is a physically appropriate parameter that can quantitatively predict the shear modulus, which is at the heart of many key properties of MGs. Moreover, the new parameter correlates strongly with atomic packing topology, and also with the activation energy for thermally activated relaxation and the propensity for stress-driven shear transformations. These correlations are expected to be robust across a very wide range of MG compositions, processing conditions and length scales.
An Incremental Parser For Abstract Meaning Representation (2017)

Meaning Representation (AMR) is a semantic representation for natural language that embeds annotations related to traditional tasks such as named entity recognition, semantic role labeling, word sense disambiguation and co-reference resolution. We describe a transition-based parser for AMR that parses sentences left-to-right, in linear time. We further propose a test-suite that assesses specific subtasks that are helpful in comparing AMR parsers, and show that our parser is competitive with the state of the art on the LDC2015E86 dataset and that it outperforms state-of-the-art parsers for recovering named entities and handling polarity.

STATUS OF THE SUPERCONDUCTING ECR ION SOURCE VENUS (2000)

A new, very high magnetic field superconducting ECR ion source, VENUS, is under development at the LBNL 88-Inch Cyclotron. It will boost the maximum energies and intensities for heavy ions from the cyclotron particularly for ions with mass greater than 60. It will also serve as R&D ion source for the proposed Rare Isotope Accelerator (RIA) project in the US, which requires up to 10 pµA of U 30+ . The superconducting magnet structure consists of three solenoids and six racetrack coils with iron poles forming the sextupole. The coils are designed to generate a 4T axial mirror field at injection and 3T at extraction and a radial sextupole field of 2.4 T at the plasma chamber wall. Test results of the magnet coils, which exceeded design requirements with minimum training, are presented. The magnet assembly with its cryostat will be enclosed by an iron shield and therefore must be designed to withstand any possible forces between coils and iron, which can be as high as 35,000 kg-force. The low energy beam transport line (LEBT) and mass analyzing system of the ion source is designed to transport a proton-equivalent current of 25mA at 20kV extraction voltage. The design of the ion source and LEBT will be discussed.
A proposal to localize an intraocular melanoma by photoacoustic spectroscopy (1981)

A method of laser-induced photoacoustic spectroscopic imaging (LIPASI) and its possible applications in biological research are described. Possible applications of this method include diagnosis of an intraocular malignant melanoma and cardial infarcts. A comparison is made between LIPASI and the normal ultrasonic imaging technique and the advantages of LIPASI are emphasized.
Multigigahertz CMOS dual-modulus prescaler IC (1988)

A low-power CMOS dual-modulus (divide-by-128/129) prescaler IC is described. The IC has been fabricated with symmetric CMOS technology that optimizes simultaneously the characteristics of both the p-channel and n-channel transistors for low-power-supply-voltage operation. Two different gate oxide thicknesses of 175 and 100 AA have been used. The best prescalar fabricated with 175-AA gate oxide functions at 2.06 GHz with 25-m W power consumption (L/sub eff/=0.5 mu m; V/sub dd/=3.5 V). Preliminary results for prescalars fabricated with 100-AA gate oxide show that 4.2-GHz operation is possible (L/sub eff/=0.4 mu m; V/sub dd/=3.5 V). Power-supply voltage as low as 1.7 V can be used for the prescalar to function at 1 GHz with a power consumption of only 4 mW.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Symbol Synchronizers in High-Speed Adaptive Receivers of Optical and Radio Frequency Range (2021)

When developing modern high-speed receivers, the problem of designing high-speed symbol synchronization systems is quite urgent. Usually these are open-loop systems, built according to the Feedforward algorithm without using additional synchronizing pulses (blind receiver). In this paper, a structural diagram of such an adaptive device for symbol synchronization is drawn up, algorithms for the functioning of its main blocks are selected and described: the block for determining the symbol frequency, the block for estimating and correcting the temporal position of the sample and the decimator. Simulation of signal processing in the digital part of a high-speed optical signal receiver with an information transmission rate of 100 Gbit/s, using DP-QPSK modulation and coding of each transmitted frame in accordance with the OTH hierarchy using standard FECs with different redundancy. Simulation confirmed the correct operation of the synchronization device and made it possible to obtain numerical indicators of the normalized synchronization error depending on the bit signal-to-noise ratio and the number of samples used. Based on the simulation results, it has been proven that the investigated symbol synchronization device retains its operability up to the signal-to-noise ratio of 10 dB. This is sufficient to provide a bit error rate of less than 10-3 even when using low position digital modulation without applying error correction coding.
A murine oral model for Mycobacterium avium subsp. paratuberculosis infection and immunomodulation with Lactobacillus casei ATCC 334 (2014)

Mycobacterium avium subsp. paratuberculosis (M. paratuberculosis) the causative agent of Johne’s disease, is one of the most serious infectious diseases in dairy cattle worldwide. Due to the chronic nature of this disease and no feasible control strategy, it is essential to have an efficient animal model which is representative of the natural route of infection as well as a viable treatment option. In this report, we evaluated the effect of different doses of M. paratuberculosis in their ability to colonize murine tissues following oral delivery and the ability of Lactobacillus casei ATCC 334, a nascent probiotic, to combat paratuberculosis. Oral inoculation of mice was able to establish paratuberculosis in a dose-dependent manner. Two consecutive doses of approximately 109 CFU per mouse resulted in a disseminated infection, whereas lower doses were not efficient to establish infection. All inoculated mice were colonized with M. paratuberculosis, maintained infection for up to 24 weeks post infection and generated immune responses that reflect M. paratuberculosis infection in cattle. Notably, oral administration of L. casei ATCC 334 did not reduce the level of M. paratuberculosis colonization in treated animals. Interestingly, cytokine responses and histology indicated a trend for the immunomodulation and reduction of pathology in animals receiving L. casei ATCC 334 treatment. Overall, a reproducible oral model of paratuberculosis in mice was established that could be used for future vaccine experiments. Although the L. casei ATCC 334 was not a promising candidate for controlling paratuberculosis, we established a protocol to screen other probiotic candidates.
Pyrimidine N-oxides. VI. The ionization constants of Pyrimidine-2,4-diamine N-oxides (1984)

The ionization constants of some pyrimidine-2,4-diamines and their N -oxides, including the drugs 'trimethoprim' and 'minoxidil', are reported. The syntheses of several pyrimidine-2,4-diamine N -oxides are described.
Learning a Recurrent Visual Representation for Image Caption Generation (2014)

In this paper we explore the bi-directional mapping between images and their sentence-based descriptions. We propose learning this mapping using a recurrent neural network. Unlike previous approaches that map both sentences and images to a common embedding, we enable the generation of novel sentences given an image. Using the same model, we can also reconstruct the visual features associated with an image given its visual description. We use a novel recurrent visual memory that automatically learns to remember long-term visual concepts to aid in both sentence generation and visual feature reconstruction. We evaluate our approach on several tasks. These include sentence generation, sentence retrieval and image retrieval. State-of-the-art results are shown for the task of generating novel image descriptions. When compared to human generated captions, our automatically generated captions are preferred by humans over $19.8\%$ of the time. Results are better than or comparable to state-of-the-art results on the image and sentence retrieval tasks for methods using similar visual features.
Exploring the effects of longstanding academic-community partnerships on study outcomes: A case study (2017)

While sustained academic and community partnerships can improve relationships between research partners, they could also influence study outcomes. Research on this issue is limited. We conducted a trial (2010-15) to test two implementation strategies for an evidence-based intervention to promote colorectal cancer (CRC) screening at community organizations in Los Angeles (<i>N</i> = 17). For both strategies, trained community health advisors (CHAs) recruited Filipino Americans (<i>N</i> = 673) who were non-adherent to CRC screening guidelines. The main study outcome was CRC screening status of participants at 6-month follow-up. This case study compares outcomes among organizations that had participated in our prior effectiveness trial and new organizations with which we had no prior relationship. Using multilevel logistic regression with multiple imputation for missing outcomes, we compared CRC screening rates among previous versus new partners controlling for study condition and organizational, CHA and participant characteristics. Screening rates were substantially higher among participants of previous versus new partner organizations in unadjusted analysis (77% versus 55%, OR 2.8, <i>p</i> = 0.12), after adjusting for organization-level variables (81% versus 42%, OR 7.5, 95% CI [2.0-28.7], <i>p</i> = 0.003) and after additionally adding CHA and participant level factors to the model (79% versus 47%, OR 5.9, CI [1.3-27.3], <i>p</i> = 0.02). Analyses using complete cases and assuming not-screened for missing outcomes indicated similar differences in screening rates (30 and 33 percentage points, respectively). Study outcomes that are achieved with long-term community partners may not be generalizable to new partners. However, inclusion of new community partners is important for external validity of dissemination efforts in community settings. NCT01351220 (ClinicalTrials.gov).
Intrinsic time-scale decomposition: time–frequency–energy analysis and real-time filtering of non-stationary signals (2006)

We introduce a new algorithm, the intrinsic time-scale decomposition (ITD), for efficient and precise time–frequency–energy (TFE) analysis of signals. The ITD method overcomes many of the limitations of both classical (e.g. Fourier transform or wavelet transform based) and more recent (empirical mode decomposition based) approaches to TFE analysis of signals that are nonlinear and/or non-stationary in nature. The ITD method decomposes a signal into (i) a sum of proper rotation components, for which instantaneous frequency and amplitude are well defined, and (ii) a monotonic trend. The decomposition preserves precise temporal information regarding signal critical points and riding waves, with a temporal resolution equal to the time-scale of extrema occurrence in the input signal. We also demonstrate how the ITD enables application of single-wave analysis and how this, in turn, leads to a powerful new class of real-time signal filters, which extract and utilize the inherent instantaneous amplitude and frequency/phase information in combination with other relevant morphological features.
