Multilayered graphene membrane as an experimental platform to probe nano-confined electrosorption (2012)

Multilayered graphene membranes (MGMs) with different packing densities were prepared and used as electrodes for supercapacitors to probe nano-confined electrosorption in porous carbon materials. The electrosorption capacity of MGMs was measured against an increasing operation rate in a series of aqueous solutions of monovalent ions. The nano-confinement effect was found prominent when the microscopic pore structure of the MGMs was controlled to be comparable to the size of hydrated ions being tested. The electrosorption capacity was found highly dependent on the type of ions. This study highlights the great potential of using easily available and structurally tunable graphene membranes as a model system to investigate fundamental problems relating to energy storage, membrane separation and nanofluidics.
An L-shaped microphone array configuration for impulsive acoustic source localization in 2-D using orthogonal clustering based time delay estimation (2013)

This paper presents an L-shaped microphone array configuration for a robust 2-D localization of an impulsive acoustic source in an indoor environment. The localization technique relies on a recently proposed time delay estimation technique based on the orthogonal clustering algorithm (TDE-OC) which is designed to work under room reverberant conditions and at low sampling rates. The TDE-OC method finds the TDEs from the sparse room impulse response (RIR) signal. The TDE's obtained from RIR adds to the robustness of the TDE-OC method against room reverberations while the low sampling rates requirement reduces the hardware and computational complexity and relaxes the communication link between the microphones and the centralized location. Experimental results show the robustness of this method in a reverberant environment with low sampling rates, when compared with the generalized cross correlation method.
A review of multi-level matrix converter topologies (2008)

Over the last few years both matrix converters and multilevel converter topologies have generated significant interest. This paper examines a family of power circuit topologies which combine these two converter types.
A new twist on gyroscopic sensing: body rotations lead to torsion in flapping, flexing insect wings (2015)

Insects perform fast rotational manoeuvres during flight. While two insect orders use flapping halteres (specialized organs evolved from wings) to detect body dynamics, it is unknown how other insects detect rotational motions. Like halteres, insect wings experience gyroscopic forces when they are flapped and rotated and recent evidence suggests that wings might indeed mediate reflexes to body rotations. But, can gyroscopic forces be detected using only changes in the structural dynamics of a flapping, flexing insect wing? We built computational and robotic models to rotate a flapping wing about an axis orthogonal to flapping. We recorded high-speed video of the model wing, which had a flexural stiffness similar to the wing of the Manduca sexta hawkmoth, while flapping it at the wingbeat frequency of Manduca (25 Hz). We compared the three-dimensional structural dynamics of the wing with and without a 3 Hz, 10° rotation about the yaw axis. Our computational model revealed that body rotation induces a new dynamic mode: torsion. We verified our result by measuring wing tip displacement, shear strain and normal strain of the robotic wing. The strains we observed could stimulate an insect's mechanoreceptors and trigger reflexive responses to body rotations.
Structure et fonction de l'endoglucanase celd de clostridium thermocellum (1992)

Clostridium thermocellum, bacterie de type gram positif, anaerobie et thermophile, est un microorganisme cellulolytique tres performant. C. Thermocellum secrete au moins 18 polypeptides differents qui sont organises en cellulosome, complexe multienzymatique et cellulolytique d'environ 2 mda. L'endoglucanase celd est un des constituants du cellulosome qui appartient a la famille e de cellulases. Le calcium diminue le k#m et augmente la thermostabilite de celd. Celd fixe le calcium avec une constante d'association de 210#6 m##1 et possede deux sites de fixation par molecule. La deletion genetique de la sequence dupliquee et conservee dans la plupart des endoglucanases et une xylanase de c. Thermocellum n'affecte ni l'activite ni la fixation du calcium. Chacun des 12 codons his du gene celd a ete mute. La proteine mutee au niveau du residu his-516 est resistante a l'inactivation par le diethylpyrocarbonate, ce qui indique que his-516 est localise dans le centre actif. Cependant, la modification chimique et la mutagenese dirigee n'entrainant qu'une inactivation de 75%, his-516 ne participe vraisemblablement pas directement a la catalyse. Douze codons de residus carboxyliques ont ete mutes. Les cinq proteines mutees et inactives ont ete purifiees. En dehors du k#c#a#t, les parametres physico-chimiques et enzymatiques de la proteine portant la mutation du residu glu-555 sont identiques a ceux de la proteine sauvage. Glu-555 est donc vraisemblablement un residu du site actif suggerant une catalyse generale de type acide-base. La mutation du residu asp-198 ou asp-201 inactivant totalement la proteine, l'un de ces deux residus pourrait egalement participer a la catalyse. La structure tri-dimensionnelle confirme que celd utilise un mecanisme catalytique de type acide-base dans lequel glu-555 protone la liaison glucosidique et asp-201 produit l'ion oh# qui participe a la substitution nucleophile du carbone anomere avec inversion de configuration. His-516 serait implique dans la fixation du substrat

Residual Neuromuscular Block (2010)

In this review, we summarize the clinical implications of residual neuromuscular block. Data suggest that residual neuromuscular block is a common complication in the postanesthesia care unit, with approximately 40% of patients exhibiting a train-of-four ratio <0.9. Volunteer studies have demonstrated that small degrees of residual paralysis (train-of-four ratios 0.7-0.9) are associated with impaired pharyngeal function and increased risk of aspiration, weakness of upper airway muscles and airway obstruction, attenuation of the hypoxic ventilatory response (approximately 30%), and unpleasant symptoms of muscle weakness. Clinical studies have also identified adverse postoperative events associated with intraoperative neuromuscular management. Large databased investigations have identified intraoperative use of muscle relaxants and residual neuromuscular block as important risk factors in anesthetic-related morbidity and mortality. Furthermore, observational and randomized clinical trials have demonstrated that incomplete neuromuscular recovery during the early postoperative period may result in acute respiratory events (hypoxemia and airway obstruction), unpleasant symptoms of muscle weakness, longer postanesthesia care unit stays, delays in tracheal extubation, and an increased risk of postoperative pulmonary complications. These recent data suggest that residual neuromuscular block is an important patient safety issue and that neuromuscular management affects postoperative outcomes.
Synchrotron-Generated Microbeam Sensorimotor Cortex Transections Induce Seizure Control without Disruption of Neurological Functions (2013)

Synchrotron-generated X-ray microplanar beams (microbeams) are characterized by the ability to deliver extremely high doses of radiation to spatially restricted volumes of tissue. Minimal dose spreading outside the beam path provides an exceptional degree of protection from radio-induced damage to the neurons and glia adjacent to the microscopic slices of tissue irradiated. The preservation of cortical architecture following high-dose microbeam irradiation and the ability to induce non-invasively the equivalent of a surgical cut over the cortex is of great interest for the development of novel experimental models in neurobiology and new treatment avenues for a variety of brain disorders. Microbeams (size 100 µm/600 µm, center-to-center distance of 400 µm/1200 µm, peak entrance doses of 360-240 Gy/150-100 Gy) delivered to the sensorimotor cortex of six 2-month-old naïve rats generated histologically evident cortical transections, without modifying motor behavior and weight gain up to 7 months. Microbeam transections of the sensorimotor cortex dramatically reduced convulsive seizure duration in a further group of 12 rats receiving local infusion of kainic acid. No subsequent neurological deficit was associated with the treatment. These data provide a novel tool to study the functions of the cortex and pave the way for the development of new therapeutic strategies for epilepsy and other neurological diseases.
Experimental investigation of a thermally driven pumping system for a potential application with a microgrid system for rural communities (2022)

Renewable energy-based microgrid systems are widely being studied as electrification methods for rural communities in developing countries. Waste heat generated by the components of the microgrid systems, such as the biogas driven generators (BDG), presents the potential of utilizing the low-grade heat in a way that can contribute to the sustainability of such energy systems. From the points of view of affordability, local manufacturability, and applicability for agriculture, thermally driven pumps (TDP) may be attractive for coupling with such microgrid systems. Therefore, the current study has focused on the development of a new type of thermally driven pumping system as a potential waste heat utilization component for microgrid applications in rural areas. A liquid piston-type TDP concept without moving parts, except few valves, was developed and parametric experimental investigations were carried out. The performance and characteristics of the system were studied, which revealed that the proposed system has a superior performance compared to the literature. It was also found that the system performance strongly depends on the heat addition rate and delivery capacity of the system, which are suitable characteristics for the intended application. Hence, the experimental data were used to estimate whether the proposed system can pump enough water that needs to be supplied for the biogas production to supply a 10 kW BDG unit of a microgrid. It was found that 87 - 93% of the total pumped water (13 - 27 m3) would be available for agricultural and other purposes while only 6 - 13% would need to be fed to the biogas digester. Generally, the results seem to be promising, and yet there are potentials for the optimization and improvement of the proposed system, hence they have been pointed out.
Identification and characterisation of a developmentally regulated mammalian gene that utilises –1 programmed ribosomal frameshifting (2001)

Translational recoding of mRNA through a -1 ribosomal slippage mechanism has been observed in RNA viruses and retrotransposons of both eukaryotes and prokaryotes. Whilst this provides a potentially powerful mechanism of gene regulation, the utilization of -1 translational frameshifting in regulating mammalian gene expression has remained obscure. Here we report a mammalian gene, Edr, which provides the first example of -1 translational recoding in a eukaryotic cellular gene. In addition to bearing functional frameshift elements that mediate expression of distinct polypeptides, Edr bears both CCHC zinc-finger and putative aspartyl protease catalytic site retroviral-like motifs, indicative of a relic retroviral-like origin for Edr. These features, coupled with conservation of Edr as a single copy gene in mouse and man and striking spatio-temporal regulation of expression during embryogenesis, suggest that Edr plays a functionally important role in mammalian development.
Towards a cognitive MAC layer: Predicting the MAC-level performance in Dynamic WSN using Machine learning (2016)

Predictable network performance is key in many low-power wireless sensor network applications. In this paper, we use machine learning as an effective technique for real-time characterization of the communication performance as observed by the MAC layer. Our approach is data-driven and consists of three steps: extensive experiments for data collection, offline modeling and trace-driven performance evaluation. From our experiments and analysis, we find that a neural networks prediction model shows best performance.
Pharmacokinetic interactions between alitretinoin and ketoconazole or simvastatin or ciclosporin A (2011)

Single and repeated doses of alitretinoin do not alter the PK of ciclosporin A and ketoconazole. Simvastatin levels were slightly but significantly reduced by co-administration of alitretinoin. Substrates of CYP3A4 did not affect the PK of alitretinoin. However, ketoconazole significantly increased the plasma levels of alitretinoin, therefore, co-administration with CYP3A4 inhibitors such as ketoconazole may require a dose reduction of alitretinoin.
The analgesic effect of therapeutic rTMS is not mediated or predicted by comorbid psychiatric or sleep disorders (2016)

Chronic Mastitis in Egypt and Morocco: Differentiating between Idiopathic Granulomatous Mastitis and IgG4‐Related Disease (2016)

Idiopathic granulomatous mastitis (IGM) is a benign, frequently severe chronic inflammatory lesion of the breast. Its etiology remains unknown and reported cases vary in their presentation and histologic findings with an optimal treatment algorithm yet to be described owing mainly to the disease's heterogeneity. IgG4-related disease (IgG4-RD) is a newly recognized systemic fibroinflammatory condition characterized by a dense lymphoplasmacytic infiltrate with many IgG4-positive plasma cells, storiform fibrosis, and obliterative phlebitis. Immunosuppressive therapy is considered to be an effective first-line therapy for IgG4-RD. We sought to clarify and classify chronic mastitis according to the histologic findings of IgG4-RD mastitis with respect to IGM and to develop a robust diagnostic framework to help select patients for optimal treatment strategies. Using the largest collection to date (43 cases from Egypt and Morocco), we show that despite sharing many features, IGM and IgG4-RD mastitis are separate diseases. To diagnostically separate the diseases, we created a classification schema-termed the Michigan Classification-based upon our large series of cases, the consensus statement on IgG4-RD, and the histologic description of IGM in the literature. Using our classification, we discerned 17 cases of IgG4-RD and 8 cases of IGM among the 43 chronic mastitis cases, with 18 indeterminate cases. Thus, our Michigan Classification can form the basis of rational stratification of chronic mastitis patients between these two clinically and histopathologically heterogeneous diseases.

Observation of excitonic and band-to-band behavior in ordered InGaP{sub 2} alloys (1994)

Photoluminescence measurements on ordered InGaP{sub 2} were studied as a function of temperature, laser power density, and magnetic field. The temperature varied between 1.4 and 300 K, the laser power densities ranged from 10 nW/cm{sup 2} to 20 W/cm{sup 2}, and the maximum magnetic field was 13.6 T. The data show both excitonic and band-to-band behavior, depending upon the incident laser power density. A consistent interpretation of all data leads to a type-II valence-band offset between the ordered domains.

Skyhook damper modification using fuzzy logic control for control effort and NVH reduction (2011)

This paper suggests a modified a semi-active vehicle suspension design based on the conventional skyhook damper mechanism. The skyhook algorithm is modified using the fuzzy logic control and a 6D IMU which measures the accelerations and angular rates of the vehicle about its C.G. to observe the vertical velocities of the sprung mass of each corner. Also, the proposed scheme utilizes the spring compression measurements of each tire to estimate the unsprung mass movement. These are combined to maximize the separation performance between the road and the sprung mass, while reducing the overall control effort and chattering that directly relates to vehicle NVH. A confirmatory assessment of the entire system is arranged via simulation scenarios involving an asymmetric vehicle chassis excitation and a sinusoidal excitation of varying frequency with the aid of well-known vehicle simulation tools, CarSim, and Matlab/Simulink.
An ultralow power CMOS/SIMOX programmable counter LSI (1997)

We designed and fabricated an extremely low-power CMOS/SIMOX programmable counter large scale integrated circuits (LSI) for high-speed phase-locked loop (PLL) frequency synthesizer applications. This was to verify the potential usefulness of ultrathin-film 0.24-/spl mu/m-gate CMOS/SIMOX process technology for creating an extremely low-power LSI containing high-speed circuits operating at frequencies of at least 1 GHz and at low supply voltages. While operating at up to 2.2 GHz and consuming only 4.5 mW at 1.5 V, it is capable of 4-GHz performance with power consumption of 19 mW at 2.5 V. Even at a low supply voltage of 1.5 V, high input-sensitivity was also achieved in the 1- to 2-GHz frequency range. These low-power and high input-sensitivity characteristics outperform those of state-of-the-art BiCMOS PLL LSIs.
