This paper introduces Icarus, a language for specifying the behavior of artificial agents that require extremely reactive, yet goal-focused control programs which include non-trivial cognitive elements. The key features of Icarus are the ability to express hierarchical objectives, actions, and plans, the use of function call semantics, and the ability to express processes as objectives, all emb...

This paper studies market-based mechanisms for coordinated dynamic task assignment in large-scale agent systems carrying out search and rescue missions. Specifically, the effect of different auction mechanisms and swapping are studied. The paper describes results from a large number of simulations.The information available to agents and their bidding strategies are used as simulation parameters...

Optical imaging has emerged as a powerful modality for studying molecular recognitions and molecular imaging in a noninvasive, sensitive, and real-time way. Some advantages of optical imaging include cost-effectiveness, convenience, and non-ionization safety as well as complementation with other imaging modalities such as positron emission tomography (PET), single-photon emission computed tomog...

This article is intended to provide an overview of various aspects of clinical PET/CT. These include discussions of: (i) Important areas of clinical application; (ii) Opportunities in clinical research; (iii) Scanner and operating-mode considerations (e.g. BGO vs. LSO, LYSO or GSO scanners, 2D vs. 3D imaging). (iv) Study-specific considerations (e.g. patient preparation and positioning is...

Fixed-dose drug products as well non-fixed hepatoprotective combinations are commonly used in modern clinical practice. Combined and concurrent use makes it possible to augment the pharmacological effects of individual agents, or extend range their potential indications. The drugs most considered for combination therapy include essential phospholipids, glycyrrhizinic acid, ursodeoxycholic silib...

Mosquito vector transmit serious infectious diseases that include dengue, chikungunya, malaria, filariasis, leishmaniasis, Japanese encephalitis, west Nile fever, yellow fever and rift valley fever. Insecticides-based control measures have historically currently been an important approach against major mosquito-borne diseases. Chemical pesticides, on the other hand, are non-selective can harm b...

We are investigating the fusion of edge information into Markov Random Fields (MRF) region growing based image segmentation. Our goal is to segment the image in a way that would take edge information into consideration. This is achieved by modifying the energy minimization process so that it would penalize merging regions that have real edges in the boundary between them. Experimental results c...

Sequence comparison is a fundamental task in pattern matching. Its applications include file comparison, spelling correction, information retrieval, and computing (dis)similarities between biological sequences. A common scheme for sequence comparison is the longest common subsequence (LCS ) metric. This paper considers the fully incremental LCS computation problem as follows: For any strings A,...

This paper describes the implementation of a Stub Generation system targeted specifically at C++. It enables distributed C++ applications to be constructed in a straightforward manner with minimal programmer assistance. The system does not require the use of an auxiliary interface definition language but instead processes existing C++ header files to maximise transparency. The generated code ex...

anti-androgens are an assorted group of drugs and compounds that reduce the levels or activity of androgen hormones within the human body. disease states in which this is relevant include polycystic ovarian syndrome, hirsutism, acne, benign prostatic hyperplasia, and endocrine related cancers such as carcinoma of the prostate. we provide an overview and discussion of the use of anti-androgen me...
