A sedimentological survey of the southwest arm of the Holocene Pigeon Creek tidal lagoon on San Salvador Island, Bahamas was conducted to determine the origin and distribution of calcareous sediments. Transect surveys, surface samples, and sediment cores were collected and examined to determine the abundance and distribution of sediments and sediment producers in the lagoon and associated tidal...

Tidal volume reduction during mechanical ventilation reduces mortality in patients with acute lung injury and the acute respiratory distress syndrome. To determine the mechanisms underlying the protective effect of low tidal volume ventilation, we studied the time course and reversibility of ventilator-induced changes in permeability and distal air space edema fluid clearance in a rat model of ...

ABSTRACT We investigate the properties of stars participating in double compact star merger events considering interacting model stable strange quark matter. matter making it compatible with recent astrophysical observations mass–radius and gravitational wave events. In this context, we consider modified MIT bag vector without self-interaction. find new upper bound on tidal deformability $1.4\,...

The problem of finding a next best viewpoint for 3D modeling or scene mapping has been explored in computer vision over the last decade. This paper tackles a similar problem, but with different characteristics, and proposes a method for dynamic best viewpoint recovery of a target point while avoiding possible occlusions. Since the environment can change, the method has to iteratively find the n...

For a long time, the bilevel programming problem has essentially been considered as a special case of mathematical programs with equilibrium constraints (MPECs), in particular when the so-called KKT reformulation is in question. Recently though, this widespread believe was shown to be false in general. In this paper, other aspects of the difference between both problems are revealed as we consi...

This paper addresses two second-best toll pricing problems, one with fixed and the other with elastic travel demands, as mathematical programs with equilibrium constraints. Several equivalent nonlinear programming formulations for the two problems are discussed. One formulation leads to properties that are of interest to transportation economists. Another produces an algorithm that is capable o...

This paper introduces six ways for handling a chain of lexicographic ordering constraint between the origins of identical orthotopes (e.g., rectangles, boxes, hyper-rectangles) subject to the fact that they should not pairwise overlap. While the first two ways deal with the integration of a chain of lexicographic ordering constraint within a generic geometric constraint kernel, the four latter ...

Symmetry is an important feature of many constraint programs. We show that any problem symmetry acting on a set of symmetry breaking constraints can be used to break symmetry. Different symmetries pick out different solutions in each symmetry class. This simple but powerful idea can be used in a number of different ways. We describe one application within model restarts, a search technique desi...

Microblog retrieval enables users to access relevant information from the huge number of tweets posted on social media. Since tweets are different from traditional documents, existing IR models might not be the optimal choice for this problem. Tie-breaking has been recently proposed as a new way of combining multiple retrieval signals. In this paper, we focus on studying the potential of this a...

The jaw plays a significant role in speech production. This work introduces a muscle activated dynamic jaw model that will be connected in the future to the 3D tongue model already developed by our group. The bone structure of the jaw, extracted from CT Images, is represented as a biomechanical model using quadrilateral shell elements. Opener and closer muscles are represented as line-segmented...
