Predictive energy harvesting from mechanical vibration using a circular piezoelectric membrane (2006)

In this study, we have investigated the capability of harvesting electrical energy from mechanical vibrations in a dynamic environment thanks to a circular piezoelectric membrane transducer. We have established an electromechanical model to predict the ability of the transducer to produce electricity. We have expressed a direct relation between the voltage able to be harvested and the acceleration of the surrounding vibrations. We have performed experiments to validate our model with a macroscopic 25 mm diameter piezoelectric membrane.
Scalable, Server-Passive, User-Anonymous Timed Release Cryptography (2005)

We consider the problem of sending messages into the future, commonly known as timed release cryptography. Existing schemes for this task either solve the relative time problem with uncontrollable, coarse-grained release time (time-lock puzzle approach) or do not provide anonymity to senders and/or receivers and are not scalable (server-based approach). Using a bilinear pairing on any Gap Diffie-Hellman group, we solve this problem by giving scalable, server-passive and user-anonymous timed release public-key encryption schemes allowing precise absolute release time specifications. Unlike the existing server-based schemes, the trusted time server in our scheme is completely passive - no interaction between it and the sender or receiver is needed; it is even not aware of the existence of a user, thus assuring the privacy of a message and the anonymity of both its sender and receiver. Besides, our scheme also has a number of desirable properties including a single form of update for all users, self-authenticated time-bound key updates, and key insulation, making it a scalable and appealing solution. It could also be easily generalized to a more general policy lock mechanism
Scalable, Parallel Best-First Search for Optimal Sequential Planning (2009)

Large-scale, parallel clusters composed of commodity processors are increasingly available, enabling the use of vast processing capabilities and distributed RAM to solve hard search problems. We investigate parallel algorithms for optimal sequential planning, with an emphasis on exploiting distributed memory computing clusters. In particular, we focus on an approach which distributes and schedules work among processors based on a hash function of the search state. We use this approach to parallelize the A* algorithm in the optimal sequential version of the Fast Downward planner. The scaling behavior of the algorithm is evaluated experimentally on clusters using up to 128 processors, a significant increase compared to previous work in parallelizing planners. We show that this approach scales well, allowing us to effectively utilize the large amount of distributed memory to optimally solve problems which require hundreds of gigabytes of RAM to solve. We also show that this approach scales well for a single, shared-memory multicore machine.
Turbulent flow between concentric rotating cylinders at large Reynolds number (1992)

Turbulent Taylor vortex flow is studied in experiments for Reynolds numbers ${10}^{3}$R${10}^{6}$. Simple scaling of the torque with Reynolds number is m/Inot observed for any range of R, although the characteristic time scales and the transport of passive scalars are found to scale with the global torque measurements. Above a nonhysteretic transition observed at R=1.3\ifmmode\times\else\texttimes\fi{}${10}^{4}$, the torque has a Reynolds number dependence similar to the drag observed in wall-bounded shear flows such as pipe flow and flow over a flat plate.
Diabetic microvascular complications: can patients at risk be identified? A review (2006)

People with diabetes have an increased risk of developing microvascular complications, diabetic retinopathy, diabetic nephropathy and diabetic neuropathy, which, if undetected or left untreated, can have a devastating impact on quality of life and place a significant burden on health care costs. In addition, diabetic microvascular complications can reduce life expectancy. The strongest risk factors are glycaemic control and diabetes duration; however, other modifiable risk factors such as hypertension, hyperlipidaemia and smoking, and unmodifiable risk factors including age at onset of diabetes and genetic factors may all play a part. Along with the presence of external risk factors, some associations have also been noted between diabetic microvascular complications themselves. There is evidence that diabetic retinopathy in association with increased blood pressure is an important risk factor for diabetic nephropathy progression. Significant correlations have also been shown between the presence of diabetic peripheral neuropathy and the presence of background or proliferative diabetic retinopathy. Clinical trials are currently in progress looking at a number of approaches to designing treatments to prevent the adverse effects of hyperglycaemia. It is essential however, that risk factors associated with the progression and development of diabetic microvascular complications are detected and treated at an early stage in order to further reduce morbidity and mortality. Considering all three complications as interrelated may well facilitate early detection of microvascular disease. Despite good long-term glycaemic and blood pressure control, diabetes remains a major cause of blindness, renal failure and amputations. As the incidence of diabetes continues to rise, the burden of diabetic microvascular complications will increase in future, hence the need for early detection. Considering the microvascular complications of diabetes as related, and enquiring proactively about complications, may well facilitate early detection of microvascular disease.
Endocarditis and biofilm-associated pili of Enterococcus faecalis (2006)

Increasing multidrug resistance in Enterococcus faecalis, a nosocomial opportunist and common cause of bacterial endocarditis, emphasizes the need for alternative therapeutic approaches such as immunotherapy or immunoprophylaxis. In an earlier study, we demonstrated the presence of antibodies in E. faecalis endocarditis patient sera to recombinant forms of 9 E. faecalis cell wall-anchored proteins; of these, we have now characterized an in vivo-expressed locus of 3 genes and an associated sortase gene (encoding sortase C; SrtC). Here, using mutation analyses and complementation, we demonstrated that both the ebp (encoding endocarditis and biofilm-associated pili) operon and srtC are important for biofilm production of E. faecalis strain OG1RF. In addition, immunogold electron microscopy using antisera against EbpA-EbpC proteins as well as patient serum demonstrated that E. faecalis produces pleomorphic surface pili. Assembly of pili and their cell wall attachment appeared to occur via a mechanism of cross-linking of the Ebp proteins by the designated SrtC. Importantly, a nonpiliated, allelic replacement mutant was significantly attenuated in an endocarditis model. These biologically important surface pili, which are antigenic in humans during endocarditis and encoded by a ubiquitous E. faecalis operon, may be a useful immunotarget for studies aimed at prevention and/or treatment of this pathogen.
Radiation cure of explosive/propellant formulations (1983)

Abstract The feasibility of radiation curing energetic compositions has been demonstrated. Binders consisting of vinyl-terminated polybutadieneacrylonitrile copolymer (VTBN) and a combination of styrene and 2-hydroxyethyl methacrylate have been cured using x-rays at a dose of 1.2 × 106 roentgen to give flexible, rubbery solid materials with rupture stress of 0.8 to 8.3 MPa and strain of 130–230 percent at 25°C. Irradiation of RDX (1,3,5-trinitro-l,3,5-triazacyclohexane) and HMX (1,3,5,7-tetranitro-l,3,5,7-tetrazacyclooctane) a t the 1.2 × 106 roentgen dose level caused no measurable ni tramine decomposition. The VTBN binder system loaded with 70% nitramine energetic filler was cured by irradiation (1.2 × 106 roentgen) t o give rubbery solids with 2.2–2.8 MPa stress a t rupture and nearly 100% strain (25°C). The filled systems display Taliani slopes, nitramine phase transitions and decomposition temperatures which are well within normal 1imits for explosives and propellants.

Relationships between enzymatic flux capacities and metabolic flux rates: Nonequilibrium reactions in muscle glycolysis (1997)

The rules that govern the relationships between enzymatic flux capacities ( V max ) and maximum physiological flux rates ( v ) at enzyme-catalyzed steps in pathways are poorly understood. We relate in vitro V max values with in vivo flux rates for glycogen phosphorylase, hexokinase, and phosphofructokinase, enzymes catalyzing nonequilibrium reactions, from a variety of muscle types in fishes, insects, birds, and mammals. Flux capacities are in large excess over physiological flux rates in low-flux muscles, resulting in low fractional velocities (% V max = v / V max × 100) in vivo . In high-flux muscles, close matches between flux capacities and flux rates (resulting in fractional velocities approaching 100% in vivo ) are observed. These empirical observations are reconciled with current concepts concerning enzyme function and regulation. We suggest that in high-flux muscles, close matches between enzymatic flux capacities and metabolic flux rates (i.e., the lack of excess capacities) may result from space constraints in the sarcoplasm.
Oral administration of taxanes (2001)

Oral treatment with cytotoxic agents is to be preferred as this administration route is convenient to patients, reduces administration costs and facilitates the use of more chronic treatment regimens. For the taxanes paclitaxel and docetaxel, however, low oral bioavailability has limited development of treatment by the oral route. Preclinical studies with mdr1a P-glycoprotein knock-out mice, which lack functional P-glycoprotein activity in the gut, have shown significant bioavailability of orally administered paclitaxel. Additional studies in wild-type mice revealed good bioavailability after oral administration when paclitaxel was combined with Pglycoprotein blockers such as cyclosporin A or the structurally related compound SDZ PSC 833. Based on the extensive preclinical research, the feasibility of oral administration of paclitaxel and docetaxel in cancer patients was recently demonstrated in our Institute. Co-administration of cyclosporin A strongly enhanced the oral bioavailability of both paclitaxel and docetaxel. For docetaxel in combination with cyclosporin A an oral bioavailability of 90% was achieved with an interpatient variability similar to that after intravenous drug administration; for paclitaxel the oral bioavailability is estimated at approximately 50%. The safety of the oral route for both taxanes is good. A phase II study of weekly oral docetaxel in combination with cyclosporin A is currently ongoing.
Bench test and preliminary results of vertical compact torus injection experiments on the STOR-M tokamak (2005)

The University of Saskatchewan compact torus injector has been modified to allow vertical injection of the compact torus (CT) into the STOR-M tokamak. The injector stayed at the horizontal position and the CT trajectory was bent by 90° using a curved conducting drift tube. The curved drift tube did not significantly slow the CT velocity down or change the CT magnetic field topology. Preliminary vertical CT injection experiments have revealed a prompt increase in the line averaged electron density and in the soft x-ray radiation level in the tokamak discharge immediately following vertical CT injection. Suppression of the m = 2 Mirnov oscillation amplitude has also been observed after CT injection.
Entre rezos, lecturas y homenajes: las conmemoraciones por el secuestro del grupo de “los 12” en la Iglesia de la Santa Cruz (Ciudad de Buenos Aires) (2017)

Entre el 8 y el 10 de diciembre de 1977 doce integrantes de un grupo mÃ¡s amplio de personas que se reunÃ­an con frecuencia en la Iglesia de la Santa Cruz (Ciudad de Buenos Aires) para organizar la bÃºsqueda de los desaparecidos, fueron secuestrados y asesinados por la Marina. Entre ellos se encontraban algunas Madres de Plaza de Mayo, dos religiosas francesas, otros familiares de desaparecidos y varios militantes polÃ­ticos. El propÃ³sito de este artÃ­culo es indagar en los significados que se elaboran desde la Iglesia de la Santa Cruz en torno a estos actores y acontecimientos relacionados con la Ãºltima dictadura militar, a la vez que explorar los modos en que las prÃ¡cticas y discursos religiosos se articulan con la construcciÃ³n y transmisiÃ³n de las memorias sobre el terrorismo de Estado. Sobre la base de observaciones realizadas en el lugar analizo las conmemoraciones que se realizan los 8 de diciembre para recordar y homenajear al llamado "grupo de los 12 de la Santa Cruz", dando cuenta de los elementos, tanto narrativos como no discursivos, que contribuyen a construir un marco de interpretaciÃ³n sobre los hechos que se conmemoran. Analizo de este modo las conexiones de sentido que, a travÃ©s de categorÃ­as como la "pasiÃ³n", se producen entre actores, figuras y escenas del campo polÃ­tico y del campo religioso
Twist Is Transcriptionally Induced by Activation of STAT3 and Mediates STAT3 Oncogenic Function (2008)

To explore the basis of metastasis, we compared the human breast cancer lines MCF-7 and MDA-MB453, which have low invasive ability, with their sublines MCF7-I4 and MDA-MB453-I4 with high invasive ability for gene expression and signaling pathways. We previously showed that the I4 lines had dramatically elevated levels of Twist compared with their parental lines. In this study, we observed significantly increased STAT3 Tyr(705) phosphorylation, but not the STAT3 protein levels, in the I4 lines. Activation of STAT3 by interleukin-6 or expression of activated Src induced Twist expression at protein and mRNA levels. Inhibiting STAT3 by a small molecule inhibitor, JSI-124, STAT3 small hairpin RNAs, or dominant negative STAT3 resulted in significant reduction of Twist protein and mRNA expression. STAT3 directly bound to the second proximal STAT3-binding site on the human Twist promoter and activated its transcriptional activity. Inhibition of STAT3 reduced migration, invasion, and colony formation of the I4 cells. Ectopic expression of Twist significantly rescued those phenotypes. Ten normal and 46 tumor specimens of breast tissues were examined for activation of STAT3 and expression of Twist. There was a strong correlation between Tyr(705) p-STAT3 and Twist level in the late stage tumor tissues. Our results indicate that activated STAT3 transcriptionally induces Twist, which plays an important role in promoting migration, invasion, and anchorage-independent growth. Together with our previous observation that Twist transcriptionally induces AKT2 to mediate Twist-promoted oncogenic functions, we conclude that STAT3, Twist, and AKT2 form a functional signaling axis to regulate pivotal oncogenic properties of cancer cells.
COMPUTER - GENERATED THREE-DIMENSIONAL MOVIES (1965)

Animated movies for educational presentations of scientific concepts are increasingly interesting a small but dedicated number of scientists, engineers, educators, and animators. The' value of animated movies for presenting complicated concepts has long been recognized. Now a new method for producing animated movies has been devised, and has led to the present renewed interest. Previously, animated movies were made a single frame at a time — a time-consuming and tedious process. Now, how­ ever, special photo-optic equipment under the control of a high-speed digital computer is being used to generate animated movies. For example, such computer-generated movies have been used at the Bell Telephone Laboratories to demonstrate the effects of different gyroscope constraints on an orbiting satellite.1 Also, an ingenious computer­ programming language has been devised for producing com­ puter movies.2 In a previous issue of Computers and Automation, I de­ scribed a computer technique for the production of threedimensional pictures.3 This technique utilized the same equipment that others had also been using to generate movies. Since a movie is essentially a series of related still pictures, the extension of my previous work to produce threedimensional movies was quite obvious. This extension is described in this article along with a few examples of some computer-generated three-dimensional movies.
Integrated supply chain design models: a survey and future research directions (2007)

Optimization models, especially nonlinear optimization models,have been widely used to solve integrated supply chain designproblems. In integrated supply chain design, the decision makerneeds to take into consideration inventory costs and distributioncosts when the number and locations of the facilities aredetermined. The objective is to minimize the total cost thatincludes location costs and inventory costs at the facilities, anddistribution costs in the supply chain. We provide a survey ofrecent developments in this research area.
Autolysis of methicillin-resistant Staphylococcus aureus is involved in synergism between imipenem and cefotiam (1995)

Imipenem-induced autolysis and the activity of imipenem plus cefotiam were studied in 16 strains of methicillin-resistant Staphylococcus aureus (MRSA). The degree of imipenem-induced autolysis and the rate of synergistic action of imipenem plus cefotiam varied among strains and did not correlate with susceptibility to either imipenem or cefotiam. However, the degree of autolysis correlated well with susceptibility to the synergistic action of imipenem plus cefotiam. In methicillin-susceptible S. aureus strains, both imipenem-induced autolysis and the synergistic activity of the combined drugs were less than those observed in MRSA strains. Differences in the degree of autolysis were not due to differences in autolytic enzyme production. The autolysis of imipenem-pretreated MRSA was enhanced further by cefotiam, while treatment of cells in the reverse order did not enhance autolysis. These findings indicate that cell wall impairment in MRSA is caused by exposure to imipenem but not to cefotiam and that this difference in drug actions results in synergism between imipenem and cefotiam. The possible participation of penicillin-binding proteins PBP 2' and PBP4 in the observed effect is discussed.
A machine learning approach to falling detection and avoidance for biped robots (2011)

A falling avoidance of biped robots is an important research topic to use the robot in a human life environment. In this paper, we propose a machine learning approach to falling detection and avoidacne for biped robots. Support Vector Machine (SVM) is used as the machine learning algorithm and it detects the falling state of the robot based on acceleration value of torso and center of pressure value of the robot. When the falling is detected, the reaction module produces gait for extending areas of supporting polygon of the robot. The main contribution of the paper is falling detection of the biped robot based on the sensor data and machine learning algorithm without explicit dynamic parameters of the robot and predefined threshold value.
Batteryless Mobile using Supercapacitor with Wireless Charging (2017)

In the current world of technology, we introduce to many new electronic gadgets. As the rate of population increases the use of this electronic gadgets are also increasing rapidly. All this electronic gadgets are run on batteries. This gadget consumes very less power than other electrical devices, but the charging time for these devices is too high. Now day's mobile phones are becoming very popular for all of us. According to a survey 4.77 Billion mobile phone users are worldwide. Our objective is to create an energy storage system for electronic gadgets that would charge in very less time. To achieve this objective we make use of Supercapacitor. Supercapacitor which is also known as ultracapacitor is a huge-capacity capacitor with the capacitance values much higher than other capacitors. The Supercapacitor has greater life than the batteries. The Supercapacitor has better characteristics than the battery. Also the Supercapacitor does not cause any hazardous problem to environment. Our secondary objective is to provide wireless charging particularly for mobile phone. With the wireless charging we never have to fiddle with the cords. Wireless charging eliminates the need of messy cords and provides a convenient charging experience by just letting you drop the device on the charging station. In today's life, multiple device wireless charging is becoming more necessary than anything.

Controllable patterning and CVD growth of isolated carbon nanotubes with direct parallel writing of catalyst using Dip Pen Nanolithography (2010)

We report a process to fabricate carbon nanotubes (CNT) by chemical vapor deposition at predetermined location. This process was enabled by patterning catalyst nanoparticles directly on silicon substrates with nanometer-scale precision using Dip Pen Nanolithography(R) (DPN(R)). A multi-pen writing method was employed to increase the patterning rate. The development of new molecular inks for the deposition of the precursor catalyst resulted in a high yield of isolated carbon nanotubes, ideal for subsequent device fabrication. Here, we demonstrate the advantages of the new method for producing high quality isolated CNT in scalable array geometries.
