Relative entropy rate based multiple hidden Markov Model Approximation

This paper proposes a novel relative entropy rate (RER) based approach for multiple HMM (MHMM) approximation of a class of discrete-time uncertain processes. Under different uncertainty assumptions, the model design problem is posed either as a min-max optimisation problem or stochastic minimisation problem on the RER between joint laws describing the state and output processes (rather than the more usual RER between output processes). A suitable filter is proposed for which performance results are established which bound conditional mean estimation performance and show that estimation performance improves as the RER is reduced. These filter consistency and convergence bounds are the first results characterising multiple HMM approximation performance and suggest that joint RER concepts provide a useful model selection criteria. The proposed model design process and MHMM filter are demonstrated on an important image processing dim-target detection problem.

Characterization of sky-region morphological-temporal airborne collision detection

Automated airborne collision-detection systems are a key enabling technology for facilitat- ing the integration of unmanned aerial vehicles (UAVs) into the national airspace. These safety-critical systems must be sensitive enough to provide timely warnings of genuine air- borne collision threats, but not so sensitive as to cause excessive false-alarms. Hence, an accurate characterisation of detection and false alarm sensitivity is essential for understand- ing performance trade-offs, and system designers can exploit this characterisation to help achieve a desired balance in system performance. In this paper we experimentally evaluate a sky-region, image based, aircraft collision detection system that is based on morphologi- cal and temporal processing techniques. (Note that the examined detection approaches are not suitable for the detection of potential collision threats against a ground clutter back- ground). A novel collection methodology for collecting realistic airborne collision-course target footage in both head-on and tail-chase engagement geometries is described. Under (hazy) blue sky conditions, our proposed system achieved detection ranges greater than 1540m in 3 flight test cases with no false alarm events in 14.14 hours of non-target data (under cloudy conditions, the system achieved detection ranges greater than 1170m in 4 flight test cases with no false alarm events in 6.63 hours of non-target data). Importantly, this paper is the first documented presentation of detection range versus false alarm curves generated from airborne target and non-target image data.

Temporal and Spatial Distribution of Finfish Bycatch in the U.S. Atlantic Bottom Longline Shark Fishery

Bycatch in U.S. fisheries has become an increasingly important issue to both fisheries managers and the public, owing to the wide range of marine resources that can be involved. From 2002 to 2006, the Commercial Shark Fishery Observer Program (CSFOP) and the Shark Bottom Longline Observer Program (SBLOP) collected data on catch and bycatch caught on randomly selected vessels of the U.S. Atlantic shark bottom longline fishery. Three subregions (eastern Gulf of Mexico, South Atlantic, Mid-Atlantic Bight), five years (2002–06), four hook types (small, medium, large, and other), seven depth ranges (<50 m to >300 m), and eight broad taxonomic categories (e.g. Selachimorpha, Batoidea, Serranidae, etc.) were used in the analyses. Results indicated that the majority of bycatch (number) was caught in the eastern Gulf of Mexico and that the Selachimorpha taxon category made up over 90% of the total bycatch. The factors year followed by depth were the most common significant factors affecting bycatch.

"Gender trouble" westernien : les représentations genrées dans les westerns de l'âge d'or étasunien (1948-1962)

Les westerns de l’âge d’or étasunien (1948-1962) mettent en scène un "gender trouble" en créant des personnages de femmes et d’hommes qui empruntent les uns et les autres aux caractéristiques genrées associées par la société nord-américaine et occidentale en général aux genres binaires du féminin et du masculin. Ce trouble genré se développe entre autres par la volonté de trois hommes de recréer la cellule familiale nucléaire conventionnelle dans "Red River" (1948) de Howard Hawks, par le rapport de peur et d’oppression du groupe social sur les individus dans "High Noon" (1952) de Fred Zinnemann et "Johnny Guitar" (1954) de Nicholas Ray, ainsi que par la rencontre opposant l’homme de l’Est et l’homme de l’Ouest dont les idéologies et les valeurs divergent dans "The Man Who Shot Liberty Valance" (1962) de John Ford.

Pathways leading to apoptosis resistance in a murine B -cell lymphoma cell system

The aberrant activation of signal transduction pathways has long been linked to uncontrolled cell proliferation and the development of cancer. The activity of one such signaling module, the Mitogen-Activated Protein Kinase (MAPK) pathway, has been implicated in several cancer types including pancreatic, breast, colon, and lymphoid malignancies. Interestingly, the activation of MAP-Kinase-Kinase-Kinase proteins often leads to the additional activation of NF-κB, a transcription factor that acts as a cell survival signal through its control of antiapoptotic genes. We have investigated the role of a specific dimer form of the NF-κB transcription factor family, NF-κB1 (p50) homodimers, in its control of the proto-oncogene, Bcl-2, and we have identified the MEK/ERK (MAPK) signaling cascade as a mediator of NF-κB1 activity. ^ Two murine B cell lymphoma cell lines were used for these studies: LY-as, an apoptosis proficient line with low Bcl-2 protein expression and no nuclear NF-κB activity, and LY-ar, a nonapoptotic line with constitutive p50 homodimer activity and 30 times more Bcl-2 protein expression than LY-as. Experiments modulating p50 activity correlated the activation of p50 homodimers with Bcl-2 expression and additional gel shift experiments demonstrated that the Bcl-2 P1 promoter had NF-κB sites with which recombinant p50 was able to interact. In vitro transcription revealed that p50 enhanced the production of transcripts derived from the Bcl-2 P1 promoter. These data strongly suggest that Bcl-2 is a target gene for p50-mediated transcription and suggest that the activation of p50 homodimers contributes to the expression of Bcl-2 observed in LY-ar cells. ^ Studies of upstream MAPK pathways that could influence NF-κB activity demonstrated that LY-ar cells had phosphorylated ERK proteins while LY-as cells did not. Treatment of LY-ar cells with the MEK inhibitors PD 98059, U0126, and PD 184352 led to a loss of phosphorylated ERK, a reversal of nuclear p50 homodimer DNA binding, and a decrease in the amount of Bcl-2 protein expression. Similarly, the activation of the MEK/ERK pathway in LY-as cells by phorbol ester led to Bcl-2 expression that could be blocked by PD 98059. Furthermore, treatment of LY-ar cells with TNFα, an IKK activator, did not change the suppressive effect of PD 98059 on p50 homodimer activity, suggesting an IKK-independent pathway for p50 homodimer activation. Lastly, all three MEK inhibitors sensitized LY-ar cells to radiation-induced apoptosis. ^ These data indicate that the activation of the MEK/ERK MAP-Kinase signaling pathway acts upstream of p50 homodimer activation and Bcl-2 expression in this B cell lymphoma cell system and suggest that the activation of MEK/ERK may be a key step in the progression of lymphoma to advanced-staged disease. Other researchers have used MEK inhibitors to inhibit cell growth and sensitize a number of tumors to chemotherapies. In light of our data, MEK inhibitors may additionally be useful clinically to radiosensitize cancers of lymphoid origin. ^
