Phase averaged velocity field within a fluidic processing jet nozzle (2001)

A nozzle consisting of a round inlet orifice expanding suddenly into a short axisymmetric chamber is the basis of an industrial burner which produces lower levels of NOx pollution than other, more conventional burners. The jet flow from the inlet orifice reattaches asymmetrically and precesses around the wall of the chamber. Phase-averaged measurements of axial velocity component in the chamber have shown that the length of the potential core of the inlet flow is about half that of an unconfined turbulent jet and the velocity decay rate is about twice as large. Entrainment by the reattaching flow induces a reverse flow in the nozzle. The measurements indicate that this reverse flow has a speed in the order of 30% of the forward flow speed. Work by other researchers on the effect of counter-flow on jets suggests that interaction between the reverse flow and the reattaching forward flow is largely responsible for the high spreading and decay rates of the latter. Introduction The Fluidic Precessing Jet (FPJ) nozzle (Figure 1) consists of a cylindrical chamber with a small axisymmetric inlet at one end and an exit lip at the other. The inlet flow separates at the abrupt inlet expansion and reattaches asymmetrically to the wall of the chamber [8]. The reattaching flow from the inlet precesses around the inside wall of the chamber and thus produces a precessing exit flow. The lip and large transverse pressure gradients near the outlet together steer the exit flow through a large angle, towards the axis and across the face of the nozzle outlet. In the cement and lime industries, the FPJ nozzle has demonstrated significant reduction in NOx emissions and improvement in product quality [4, 3]. These benefits are a result of differences between the combustion in the flow field of traditional axial-jet burners and the combustion produced by the FPJ [9] — which in turn depends on the differences in the turbulentjet flow field. Since the discovery of the FPJ by Nathan [7] and its first application as an industrial burner, a significant research effort has been directed at optimising the geometry of the FPJ nozzle and at understanding the FPJ flow. The early research on the FPJ consisted of flow visualisation studies, combustion trials and experiments with pressure transducers and uncalibrated hot-wire inlet flow reverse induced air flow
Middleware for video surveillance networks (2006)

Automated video surveillance networks are a class of sensor networks with the potential to enhance the protection of facilities such as airports and power stations from a wide range of threats. However, current systems are limited to networks of tens of cameras, not the thousands required to protect major facilities. Realising thousand camera automated surveillance networks demands middleware and architectural support; replacing the ad hoc approaches used in current systems with robust and scalable methods.This paper introduces middleware supporting both computation and communication in automated video surveillance networks. The computational approach is based on the Blackboard architectural style, which is widely used in signal processing and AI. Communication on the surveillance network follows the service oriented model, with publish/subscribe messaging; providing scalability, availability and the ability to integrate separately developed surveillance services. The middleware is demonstrated through its application to an important class of surveillance algorithms.
A distributed stochastic perception-action loop model of cell motility (2013)

In this paper, we present a novel framework for the modeling of cell-migration, and more specifically the migration of human keratinocytes. The model decouples the embodiment of an artificial cell into two elements. A cell-body is implemented by two sets of springs forming a membrane and a supporting cortical-cytoskeleton, which allows for cell-body rigidity and flexibility. The leading-edge, a structure spreading around the cell-body, is simulated with a stochastic cellular-automata. It defines the migratory forces that pull the cell-body according to its local spread around the cell. The overall movement of the leading-edge depends on stochastic interaction with the environment and guides the whole cell movement through spatiotemporal integration of local forces. We demonstrate that our cell migration model allows for spontaneous symmetry-breaking and directed cell movement and has in-built obstacle-avoidance, closely mimicking the migration of living cells. The model is extended to simulate chemotactic behavior, the artificial cell can sense and move along a gradient with its trajectory depending on the cell shape, stiffness and leading-edge dynamics. In summary, we have developed a novel cell migration model with emergent properties, wherein local forces create an integrated cell movement. The presented interplay of the distributed physical and an informational embodiment is not limited in reach to the example of cell migration, but can of interest for design of perception-action loops and sensor evolution in general.
Flowing and Vibrant Organocatalysis (2012)

A bright start for a new beginning: Since the rediscovery of organocatalysis by List, MacMillan, Barbas, Jørgensen, Terada, Akiyama, and many others, organocatalysis has become a flowing and vibrant field of research.
<title>Optical fiber crack sensor for concrete structures</title> (1997)

The condition of concrete structures can be assessed through the monitoring of crack openings. Researchers at MIT and Brown University have recently developed a novel concept for the sensing of cracks in concrete structures. The sensing capability is based on the light loss as microbending occurs in a fiber bridging the crack. To use the sensor, only the crack plane orientation in the structure (rather than the exact crack locations) needs to be known. With the use of OTDR, distributed sensing is possible. In this paper, the novel crack sensing concept is first introduced. To guide the design of sensors for various performance requirements, a theoretical model is developed to relate signal loss and crack opening. Prediction from the mold is compared with experimental results. Using laboratory-sized specimens, the detection of both surface and interior cracks are demonstrated.
Cellulose promotes extracellular assembly of Clostridium cellulovorans cellulosomes (1994)

Cellulosome synthesis by Clostridium cellulovorans was investigated by growing the cells in media containing different carbon sources. Supernatant from cells grown with cellobiose contained no cellulosomes and only the free forms of cellulosomal major subunits CbpA, P100, and P70 and the minor subunits with enzymatic activity. Supernatant from cells grown on pebble-milled cellulose and Avicel contained cellulosomes capable of degrading crystalline cellulose. Supernatants from cells grown with cellobiose, pebble-milled cellulose, and Avicel contained about the same amount of carboxymethyl cellulase activity. Although the supernatant from the medium containing cellobiose did not initially contain active cellulosomes, the addition of crystalline cellulose to the cell-free supernatant fraction converted the free major forms to cellulosomes with the ability to degrade crystalline cellulose. The binding of P100 and P70 to crystalline cellulose was dependent on their attachment to the endoglucanase-binding domains of CbpA. These data strongly indicate that crystalline cellulose promotes cellulosome assembly.
Visual field map clusters in human cortex (2005)

We describe the location and general properties of nine human visual field maps. The cortical location of each map, as well as many examples of the eccentricity and angular representations within these maps, are shown in a series of images that summarize a large set of functional MRI data. The organization and properties of these maps are compared and contrasted with descriptions by other investigators. We hypothesize that the human visual field maps are arranged in several clusters, each comprising a group of maps that share a common foveal representation and semicircular eccentricity map. The spatial organization of these clusters suggests that the perceptual processing within each cluster serves related functions.
Bandwidth Limits and Other Considerations for Monostatic RCS Reduction by Virtual Shaping (2004)

This work addresses some major issues in the adaptation and application of microstrip patch antenna and reflectarray technology to radar cross section reduction by virtual shaping. We define virtual shaping to be any technique used to cause the shape and orientation of an object as it affects a scattered radar signal to differ from the actual physical shape and orientation of the object. This is accomplished by introducing a linear phase gradient on the incident wave as it is scattered from various parts of the target surface. By this method a vertical surface can be made to appear to radar to be skewed from the vertical as is done in conventional shaping for radar cross section reduction. Virtual shaping has the potential to reduce the negative impacts imposed by conventional shaping on other ship design considerations such as hydrodynamics, stability, payload, and arrangements while maintaining or enhancing the signature control aspects. Microstrip patch antenna and reflectarray technologies offer a theoretical and practical basis for development of virtual shaping techniques; however, the goals of antenna design and the radiation characteristics of reflectarrays when applied to conventional uses of these technologies differ from those considerations when applied to signature control and radar cross section reduction. The major issues of these technologies that become more critical when applied to virtual shaping include (1) limited bandwidth, (2) high sidelobes, and (3) reflections from exposed dielectric surfaces. This paper summarizes efforts that have the potential to extend these technologies to virtual shaping.

Informed-source coding-on-demand (ISCOD) over broadcast channels (2002)

We present the informed source coding on-demand (ISCOD) approach for efficiently supplying non-identical data from a central server to multiple caching clients through a broadcast channel. The key idea underlying ISCOD is the joint exploitation of the data already cached by each client, the server's full awareness of client cache contents and client requests, and the fact that each client only needs to be able to derive the items requested by it rather than all the items ever transmitted or even the union of the items requested by the different clients. We present a set of two-phase ISCOD algorithms. The server uses these algorithms to assemble ad-hoc error correction sets based its knowledge of every client's cache content and of the items requested by it; next, it uses error-correction codes to construct the data that is actually transmitted. Each client uses its cached data and the received supplemental data to derive the items that it has requested. This technique achieves a reduction of up to tens of percents in the amount of data that must be transmitted in order for every client to be able to derive the data requested by it. Finally, we define k-partial cliques in a directed graph, and cast the two phase approach in terms of partial clique covers. As a byproduct of this work, bounds and a close approximation for the expected cardinality of the maximum matching in a random graph have been derived and are outlined.
807 Fabrication of Nanogap Electrode using Low-Current Electromigration Method (2011)

Recently, in order to apply single-molecule devices and nonvolatile memory devices, mass-production techniques for nanogap electrodes have been required. Electromigration method is one of the most useful procedures for fabrication of nanogap structure, gap size of which is below 5 nm. However, because large-current flow and long-time consuming are also necessary for the method, this is not suitable for mass-production. Therefore, we devised a new fabrication technique to adapt electromigration during metal deposition. This technique achieved simultaneously fabrication of nanogap structure and metal electrodes by low-current electromigration.

C5b-9-induced Endothelial Cell Proliferation and Migration Are Dependent on Akt Inactivation of Forkhead Transcription Factor FOXO1 (2006)

Migration and proliferation of aortic endothelial cells (AEC) are critical processes involved in angiogenesis, atherosclerosis, and postangioplasty restenosis. Activation of complement and assembly of the C5b-9 complement complex have been implicated in the pre-lesional stage of atherogenesis and progression of the atherosclerotic lesion. We have shown that C5b-9 induces proliferation and activates phosphatidylinositol 3-kinase (PI3K), but it is unknown whether this can lead to activation of Akt in AEC, a major downstream target of PI3K, or if C5b-9 can induce the migration of AEC, a critical step in angiogenesis. In this study, we show that C5b-9 induces AEC proliferation and migration and also activates the PI3K/Akt pathway. C5b-9 activates Akt as shown by in vitro kinase assay and phosphorylation of Ser-473. C5b-9-induced cell cycle activation was inhibited by pretreatment with LY294002 (PI3K inhibitor), SH-5 (Akt inhibitor), or transfection with Akt siRNA. These data suggests that the PI3K/Akt pathway is required for C5b-9-induced cell cycle activation. FOXO1, a member of forkhead transcription factor family, was phosphorylated at Ser-256 and inactivated after C5b-9 stimulation as shown by a decrease in DNA binding and cytoplasmic relocalization. Cytoplasmic relocalization was significantly reduced after pretreatment with LY294002, SH-5, or transfection with Akt siRNA. Silencing FOXO1 expression using siRNA stimulated AEC proliferation and regulated angiogenic factor release. Our data indicate that C5b-9 regulation of the cell cycle activation in AEC through Akt pathway is dependent on inactivation of FOXO1.
Toward complex visibilities using optical interferometry: multiwavelength phase referencing (2006)

We report on experiments in multi-wavelength phase referencing using the Navy Prototype Optical Interferometer (NPOI). In these experiments we use the unique capability of the NPOI to simultaneously observe 16 spectral channels covering 512-850 nm on multiple baselines simultaneously. We present observations of the well-known Be star ζ Tauri using custom filters which allow us to isolate the Hα line in a single spectral channel while the other channels observe the stellar continuum. Since the central star is unresolved, we can use the data in the continuum channels to calibrate the spectral line data. Using the phase information recovered in this way, it is possible for the first time to use standard techniques to construct simple images of the line-emitting region around the star.

14. Asymptotic Behavior (1999)

In this chapter we shall focus on the behavior of the Riccati recursion as time progresses to infinity. In order to do so, we shall confine our attention to time-invariant state-space models. Our main interest is to find conditions under which, for a given initial condition, the solution to the Riccati recursion converges to a solution of the DARE. The main result uses an identity relating solutions of the Riccati recursion for different initial conditions and states that if a certain sequence of matrices is uniformly nonsingular, then the Riccati recursion converges to the unique stabilizing solution (assuming such a solution exists) of the DARE. In the general case, the aforementioned nonsingularity conditions need to be recursively checked. However, in some special cases they can be reduced to more simple and more explicit requirements on the initial condition. In particular, when the coefficient matrices of the Riccati recursion are positive semidefinite (i.e., in the case), we can guarantee the convergence of the Riccati recursion for some indefinite, and even negative semidefinite, initial conditions (provided they are bounded below by a certain negative semidefinite matrix). Moreover, in the case frequently encountered in filtering and control, we can guarantee convergence for all positive semidefinite initial conditions that are less than or equal to a certain positive semidefinite matrix. Finally, we mention some implications of the results obtained here for different problems in which these Riccati equations arise.

Performance of proex c and pretect hpv‐proofer e6/e7 mrna tests in comparison with the hybrid capture 2 hpv dna test for triaging ascus and lsil cytology (2013)

The clinical usefulness of the ProEx C (Becton Dickinson) and PreTect HPV-Proofer E6/E7 mRNA tests (Proofer; Norchip) for the triage of ASCUS and LSIL cytology was determined in comparison with the Hybrid Capture 2 HPV DNA test (HC2; Qiagen). The study population consisted of women with a history of abnormal cytology referred to colposcopy. Histology-confirmed CIN 2+ served as the disease endpoint. The study was based on 1,360 women (mean age 30.7 years), of whom 380 had CIN 2+. Among 315 with ASCUS (CIN 2+, n = 67), the sensitivities of ProEx C, Proofer, and HC2 to detect CIN 2+ were, 71.6, 71.6, and 95.5%, respectively, with a corresponding specificity of 74.6, 74.2, and 35.1%. Among 363 with LSIL (CIN 2+, n = 108), the sensitivities of ProEx C, Proofer, and HC2 were, 67.6, 74.1, and 96.3%, respectively, with a corresponding specificity of 60, 68.2, and 18.4%. Among 225 HC2-positive ASCUS (CIN 2+, n = 64), 105 tested positive by ProEx C, reducing colposcopy referral by 53.3% and detecting 71.9% of CIN 2+; Proofer was positive in 112/225, reducing colposcopy referral by 50.2% and detecting 75.0% of CIN 2+. Among 312 HC2-positive LSIL (CIN 2+, n = 104), 160 tested positive by ProEx C, reducing coloposcopy referral by 48.7% and detecting 66.3% of CIN 2+; Proofer was positive in 159/312, reducing colposcopy referral by 49.0% and detecting 75.0% of CIN 2+. In conclusion, both ProEx C and Proofer have a similar performance profile with a significantly higher specificity but lower sensitivity than HC2 for the detection of CIN 2+. Consequently, although they can reduce colposcopy referral, they will miss a proportion of CIN 2+ cases. This is a major limitation and should be taken into account if these tests are considered for ASCUS or LSIL triage.
