An optimal design of a grid connected hybrid wind/photovoltaic/fuel cell system for distributed energy production (2005)

This paper proposes a hybrid energy system consisting of wind, photovoltaic and fuel cell designed to supply continuous power to the load. A simple and economic control with DC-DC converter is used for maximum power point tracking and hence maximum power extraction from the wind turbine and photovoltaic array. Due to the intermittent nature of both the wind and photovoltaic energy sources, a fuel cell is added to the system for the purpose of ensuring continuous power flow. The fuel cell is thus controlled to provide the deficit power when the combined wind and photovoltaic sources cannot meet the net power demand. In worst environmental conditions, when there is no output power from the wind or photovoltaic sources, the fuel cell will operate at its rated power of 10 kW. Hence this system under any operating condition will ensure a minimum power flow of 10 kW to the load. This hybrid system allows maximum utilization of freely available renewable energy sources like wind and photovoltaic and demand-based utilization of hydrogen-based fuel cell. The proposed system is attractive owing to its simplicity, ease of control and low cost. Also it can be easily adjusted to accommodate different and any number of energy sources. A complete description of this system is presented along with its simulation results which ascertain its feasibility.
Practice Effects Associated with the Repeated Assessment of Cognitive Function Using the CogState Battery at 10-minute, One Week and One Month Test-retest Intervals (2006)

There are many situations in which cognitive tests need to be administered on more than two occasions and at very brief test-retest intervals to detect change in group performance. However, previous literature has not specifically addressed these important issues. The main aim of the current study was to examine these two factors by using a computerized cognitive battery designed specifically for the repeated assessment of cognition (i.e., CogState) in healthy young adult individuals. A further aim of the study was to examine how many times the battery needed to be completed before performance, as measured by the battery, stabilized. Forty-five adults (age range: 18-40 years) completed the battery four times at 10-minute test-retest intervals, and a fifth time at an interval of one week. The results illustrated that when brief test-retest intervals were used (i.e., 10 minutes), performance stabilized after the second assessment, as significant practice effects were generally observed between the first and the second assessments. Practice effects were also observed on some of the tasks at a one-week test-retest interval. Due to these findings, 55 adults (age range: 18-40 years) completed the battery twice at 10-minute test-retest intervals (i.e., to eliminate the initial practice effect), and a third time at an interval of one month. No practice effects were observed. The implications of the results are discussed in terms of methods that can be adopted in order to minimize practice effects when this particular cognitive battery is used.
A Thermostable, Flexible RNA Vaccine Delivery Platform for Pandemic Response (2021)

Abstract Current RNA vaccines against SARS-CoV-2 are limited by instability of both the RNA and the lipid nanoparticle delivery system, requiring storage at −20°C or −70°C and compromising universally accessible vaccine distribution. This study demonstrates the thermostability and adaptability of a nanostructured lipid carrier (NLC) RNA vaccine delivery system for use in pandemic preparedness and pandemic response. Liquid NLC is stable at refrigerated temperatures for ≥ 1 year, enabling stockpiling and rapid deployment by point-of-care mixing with any vaccine RNA. Alternatively, NLC complexed with RNA may be readily lyophilized and stored at room temperature for ≥ 8 months or refrigerated temperature for ≥ 21 months. This thermostable RNA vaccine platform could significantly improve distribution of current and future pandemic response vaccines, particularly in low-resource settings. One Sentence Summary An RNA vaccine delivery system stable at room temperature for 8+ months and refrigerated for 21+ months.
Advanced electro-mechanical micro-shutters for thermal infrared night vision imaging and targeting systems (2007)

Un-cooled microbolometer sensors used in modern infrared night vision systems such as driver vehicle enhancement (DVE) or thermal weapons sights (TWS) require a mechanical shutter. Although much consideration is given to the performance requirements of the sensor, supporting electronic components and imaging optics, the shutter technology required to survive in combat is typically the last consideration in the system design. Electro-mechanical shutters used in military IR applications must be reliable in temperature extremes from a low temperature of -40°C to a high temperature of +70°C. They must be extremely light weight while having the ability to withstand the high vibration and shock forces associated with systems mounted in military combat vehicles, weapon telescopic sights, or downed unmanned aerial vehicles (UAV). Electro-mechanical shutters must have minimal power consumption and contain circuitry integrated into the shutter to manage battery power while simultaneously adapting to changes in electrical component operating parameters caused by extreme temperature variations. The technology required to produce a miniature electro-mechanical shutter capable of fitting into a rifle scope with these capabilities requires innovations in mechanical design, material science, and electronics. This paper describes a new, miniature electro-mechanical shutter technology with integrated power management electronics designed for extreme service infra-red night vision systems.
Review of Magnetic Flywheel Energy Storage Systems (2014)

This study studies an overview of magnetic flywheel energy storage system. Energy storage is an integral part of any critical power system, as this stored energy is used to offset interruptions in the power delivered system from either a utility or an on-site generator. Magnetic flywheel as mechanical batteries using composite rotor, magnetic support bearings as well as power electronics to store electrical energy to replace stone wheel and chemical batteries has resulted in high power and energy densities. Traditionally, capacitors are used for short term storage (Î¼s-ms) and filtering, chemical batteries are used for intermediate storage (min-h) and diesel fuel is used for long-term storage (h-days). Electricity generated from renewable sources, which has shown remarkable growth worldwide, can rarely provide immediate response to demand as these sources do not deliver regular supply easily adjustable to consumption needs. Thus, the growth of this decentralization production means greater network load stability problems and requires energy storage, generally using lead acid batteries as a potential solution. Finally the integration of all subsystems optimally of the magnetic flywheel system has resulted in a mechanical battery which can supply more efficient, reliable and uninterrupted power to meet the ever increasing demand of industrial machinery and automobiles.

Vehicle velocity estimation by dynamic inversion of wheel force generation (2009)

Automotive vehicle velocity estimation with only steering angle and angular wheel velocities as available measurements is considered in the paper at hand. The approach is based on dynamic inversion of wheel force generation combined with stationary Kalman filter design. A detailed assessment of the results by comparison with measured data is given. Possible applications include hierarchical monitoring of vehicle dynamics sensor networks.
Theory of Asymmetric Organocatalysis of Aldol and Related Reactions:  Rationalizations and Predictions (2004)

Computational studies have led to models to understand some classic and contemporary asymmetric reactions involving organocatalysts. The Hajos-Parrish-Eder-Sauer-Wiechert reaction and intermolecular aldol reactions as well as Mannich reactions and oxyaminations catalyzed by proline and other amino acids, and Diels-Alder reactions catalyzed by MacMillan's chiral amine organocatalysts have been studied with density functional theory. Quantitative predictions for several new catalysts and reactions are provided.
Recycling of Rare Earth Magnet Scraps: Part I Carbon Removal by High Temperature Oxidation (2001)

In the recycling of the permanent Nd–Fe–B magnet, the carbon such as free carbon and carbides at the grain boundary segregation in the magnet scrap are elements that are harmful and which obstruct the magnet performance. The removal of the carbon is currently a major problem. Remelting of scraps should, therefore, be done on condition that the carbon content is lowered to an appropriate level prior to melting. The aim of this work was to open the route for decarburization of the Nd magnet powder scraps with high carbon, as well as of the sintered body scraps with moderate carbon concentration. Decarburization via oxidation in air allowed the removal of not only free carbon but also grain boundary carbides at temperatures higher than 1273 K down to 300 mass ppm. However, an increase in the oxygen content is inevitable with the high temperature oxidation. The next step was then to reduce the iron oxide by heating it in a hydrogen atmosphere at 1273 K and subsequently to eliminate the oxygen combined with the rare-earth constituent using calcium which has a strong affinity with oxygen. The basic technology for the recycling process of the permanent Nd–Fe–B magnet scraps was discussed.
Donald McGavran’s Theological Foundations for “Effective Evangelism” (2010)

From its inception, the Church Growth Movement, as espoused by its “father,” Donald A. McGavran, was focused on “effective evangelism.” The purpose of this article is to identify McGavran’s theology of evangelism as revealed in his published writings. While he may never have delineated a precise theology of evangelism, one can find in McGavran’s writings an orthodox, if sometimes incomplete, system regarding the working of God in the salvation of men and women. The article investigates McGavran’s views on Scripture, the content and proclamation of the gospel, and on key soteriological issues.

CAC performance with self-similar traffic: simulation study and performance results (2003)

This paper investigates, through simulation, the performance of five connection admission control (CAC) algorithms used in ATM networks, namely: PCR CAC, SCR CAC, AVG CAC, GCAC, and Norros CAC, when presented with synthetically generated homogeneous self-similar traffic sources. Various traffic and system parameters have been used. The simulation results show that statistical multiplexing gains both within a source and across sources should be exploited to improve network resource utilization. Source granularity, and variability have been shown to have the most impact on the CAC performance. The limited impact of the Hurst parameter shows that the long-range correlation structure of the traffic sources can be neglected in evaluating CAC performance, at least when the buffer size is small. The CAC algorithms should be more conservative when link capacity is low and more aggressive when link capacity is high. While none of the CAC algorithms performs satisfactorily in all scenarios, the Norrors CAC and AVG CAC perform better than the others.
Fluid animation with explicit surface meshes and boundary-only dynamics (2010)

An explicit method for fluid surface tracking is presented. The method represents the surface as a triangulated mesh of points in space, rather than as an implicit surface function. Utilizing well-developed algorithms designed for collision detection and resolution in cloth simulation, the system is able to handle topology changes robustly and efficiently. When fluid surfaces collide, we perform topology changes only in the most trivial cases -- we reject any degenerate cases and use the cloth algorithm to keep the surfaces separated. Taking advantage of the explicit surface representation, we introduce new approaches to simulating surface tension and conserving fluid volume. Finally, we propose a boundary element method for enforcing fluid incompressibility which uses only data points on the fluid surface, rather than a full volumetric discretization of the fluid over a grid.
Inducer Expulsion and the Occurrence of an HPr(Ser-P)-Activated Sugar-Phosphate Phosphatase in Enterococcus Faecalis and Streptococcus Pyogenes (1996)

Inducer expulsion, a phenomenon in which rapidly metabolizable sugars cause cytoplasmic dephosphorylation and efflux of pre-accumulated sugar-phosphates (sugar-P), has been documented for Streptococcus pyogenes, Streptococcus bovis, and Lactococcus lactis, but not for other Gram-positive bacteria. Using intact cells and membrane vesicles, we show that Enterococcus faecalis exhibits both inducer exclusion and inducer expulsion, and that the latter phenomenon is dependent on the metabolite-activated ATP-dependent HPr(Ser) kinase that phosphorylates Ser-46 in HPr of the phosphotransferase system. A small, heat-stable, membrane-associated, HPr(Ser-P)-activated sugar-P phosphatase (Pase II), previously identified only in Lc. lactis, is shown to be present in extracts of Enterococcus faecalis and Streptococcus pyogenes but not in those of Staphylococcus aureus, Streptococcus mutans, Streptococcus salivarius, or Bacillis subtilis, organisms that do not exhibit the inducer expulsion phenomenon. Further, Lactobacillus brevis, an organism that exhibits inducer expulsion by a different mechanism, also apparently lacks Pase II. The results reveal that Pase II is present in those organisms that exhibit the coupled sugar-P hydrolysis/expulsion mechanism but not those that lack this mechanism. They provide correlative evidence that Pase II initiates inducer expulsion in species of enterococci, streptococci and lactococci.
TRPV4 is necessary for trigeminal irritant pain and functions as a cellular formalin receptor (2014)

Detection of external irritants by head nociceptor neurons has deep evolutionary roots. Irritant-induced aversive behavior is a popular pain model in laboratory animals. It is used widely in the formalin model, where formaldehyde is injected into the rodent paw, eliciting quantifiable nocifensive behavior that has a direct, tissue-injury-evoked phase, and a subsequent tonic phase caused by neural maladaptation. The formalin model has elucidated many antipain compounds and pain-modulating signaling pathways. We have adopted this model to trigeminally innervated territories in mice. In addition, we examined the involvement of TRPV4 channels in formalin-evoked trigeminal pain behavior because TRPV4 is abundantly expressed in trigeminal ganglion (TG) sensory neurons, and because we have recently defined TRPV4's role in response to airborne irritants and in a model for temporomandibular joint pain. We found TRPV4 to be important for trigeminal nocifensive behavior evoked by formalin whisker pad injections. This conclusion is supported by studies with Trpv4(-/-) mice and TRPV4-specific antagonists. Our results imply TRPV4 in MEK-ERK activation in TG sensory neurons. Furthermore, cellular studies in primary TG neurons and in heterologous TRPV4-expressing cells suggest that TRPV4 can be activated directly by formalin to gate Ca(2+). Using TRPA1-blocker and Trpa1(-/-) mice, we found that both TRP channels co-contribute to the formalin trigeminal pain response. These results imply TRPV4 as an important signaling molecule in irritation-evoked trigeminal pain. TRPV4-antagonistic therapies can therefore be envisioned as novel analgesics, possibly for specific targeting of trigeminal pain disorders, such as migraine, headaches, temporomandibular joint, facial, and dental pain, and irritation of trigeminally innervated surface epithelia.
Molecular beam epitaxy of GaAs/AlGaAs superlattice heterostructures on nonplanar substrates (1987)

GaAs/AlGaAs superlattice heterostructures with layer thicknesses ≲100 Å were grown by molecular beam epitaxy on nonplanar GaAs substrates. The resulting superlattices exhibit different periods, depending on the crystal plane on which they grow. Period variation of more than 50%, from 180 to 80 Å, was obtained for adjacent superlattice sections. The transition between regions of different periodicity was mostly smooth and occurred within lateral dimensions ≲100 Å. Our results suggest that molecular beam epitaxy of superlattice heterostructures on patterned substrates provides a method for obtaining controllable lateral variations in physical properties which depend on the superlattice period. In particular, by growing quantum well heterostructures on nonplanar substrates, it might be possible to utilize the strong dependence of the carrier confinement energy on the well thickness in order to achieve lateral carrier confinement.
Distribution of Antibiotic MICs for <i>Helicobacter pylori</i> Strains over a 16-Year Period in Patients from Seoul, South Korea (2004)

Recently, the development of antibiotic resistance emerged as a significant clinical problem in the eradication of Helicobacter pylori. We investigated the MICs of antibiotics for 135 H. pylori isolates from adults in Seoul, South Korea, over the past 16 years. The MICs of amoxicillin, clarithromycin, metronidazole, tetracycline, azithromycin, and ciprofloxacin increased from 1987 to 2003. Rates of primary resistance to clarithromycin increased from 2.8% in 1994 to 13.8% in 2003. The A2144G mutation was frequently observed in the 23S rRNA gene in clarithromycin-resistant isolates. The increase in resistance to clarithromycin seems to result in a decrease in eradication efficacy for H. pylori. These results suggest that the MICs of several antibiotics for H. pylori have increased over the past 16 years in Seoul.
Reactive ion etching of GaAs, AlGaAs, and GaSb in Cl2 and SiCl4 (1990)

High rate (≤10 μm min−1 ) etching of GaAs, AlxGa1−x As, and GaSb in Cl2/Ar or SiCl4/Ar discharges is reported. The etching was investigated as a function of discharge pressure, power density and composition, and changes in the etching rate of AlxGa1−xAs when SF6 was added to the gas mixtures. Highly anisotropic etching was achieved with SiCl4 for all materials, whereas a greater degree of chemical etching was evident with Cl2. Provided self-biases were ≤50 V, excellent Schottky diode characteristics were exhibited by TiPtAu contacts on SiCl4 or Cl2 etched GaAs surfaces. Energetic-ion bombardment caused carrier compensation up to 2200 Å from the surface in n-type (1017 cm−3 ) GaAs, with this depth being less for lower self-biases. Photoluminescence decreases of 2–25 times were observed after reactive ion etching of GaAs for both types of discharge. Chlorine residues were typically present to a depth of &lt;20 Å after etching, with cleaner surfaces obtained with SiCl4 than with Cl2.
Protein kinases mediate ligand-independent derepression of sumoylated progesterone receptors in breast cancer cells (2009)

In advanced breast tumors, protein kinases are upregulated and steroid hormone receptors often function independently of ligand. Herein, we explored mechanisms of ligand-independent progesterone receptor (PR) activity. We showed previously that growth factor-induced phosphorylation of PR Ser-294 blocks PR Lys-388 sumoylation. SUMO-deficient mutant PR-B (K388R) thus provides a model receptor for the study of PR function in the context of high kinase activities. T47D cells stably expressing K388R PR-B exhibited increased ligand-independent proliferation and growth in soft agar relative to cells expressing wt PR-B or phospho-mutant (sumoylated) S294A PR-B. Expression of selected PR target genes (HB-EGF, IRS-1, and STC1) was significantly elevated in cells containing desumoylated (K388R) PR-B. Basal PR transcriptional activity occurred independently of progestins, was increased by activated CDK2, and attenuated by RU486. Notably, ChIP assays demonstrated that K388R PR-B and SRC1 were constitutively recruited to the STC1 promoter in the absence of progestin; PR Lys-388 sumoylation was required for HDAC3 recruitment. Knock-down of STC1 inhibited proliferation of cells expressing K388R PR-B. These data suggest a mechanism whereby phosphorylated, and thus desumoylated, PRs mediate increased expression of growth promoting genes. Our data explain why breast cancer models often remain insensitive to progestins, but are growth-inhibited by antiprogestins, and underscore the need to target PR-B and associated kinase activities as part of breast cancer therapy.
