We propose a new framework for how to use sequential Monte Carlo (SMC) algorithms for inference in probabilistic graphical models (PGM). Via a sequential decomposition of the PGM we find a sequence of auxiliary distributions defined on a monotonically increasing sequence of probability spaces. By targeting these auxiliary distributions using SMC we are able to approximate the full joint distrib...

Pragmatic General Multicast (PGM) is a reliable multicast protocol, designed to minimize both the probability of negative acknowledgements (NAK) implosion and the loading of the network due to retransmissions of lost packets. This protocol was presented to the Internet Engineering Task Force as an open reference specification. In this paper, we focus on the main reliability property which PGM i...

We demonstrate a two phase classification method, first of individual pixels, then of fixed regions of pixels for scene classification—the task of assigning posteriors that characterize an entire image. This can be realized with a probabilistic graphical model (PGM), without the characteristic segmentation and aggregation tasks characteristic of visual object recognition. Instead the spatial as...

This communication reports the X-ray crystal structure of the alpha-d-galactose-1-phosphate complex with that of Lactococcus lactis beta-phosphoglucomutase (beta-PGM) crystallized in the presence of Mg2+ cofactor and the enzyme-to-phosphorus ratio determined by protein and phosphate analyses of the crystalline complex. The 1:1 ratio determined for this complex was compared to the 1:2 ratio dete...

Real-time signal-processing applications for high assurance systems are commonly designed using a processing-graph software architecture. Here we demonstrate the management of latency and buffer requirements in such an architecture—the US Navy’s processing graph method (PGM). By applying recent results in real-time scheduling theory to the subset of PGM employed by the US DARPA rapid prototypin...

Recruitment of new blood vessels plays a crucial role in tumor survival and growth. Several agents that act as angiogenesis inhibitors are currently being investigated as anti-tumor agents. Proteoglycan extract (PGM) was tested for anti-angiogenic, immunostimulatory, and anti-neoplastic activity. PGM is a non-toxic extract of the ubiquitous plant, Convolvulus arvensis. In the chicken egg chorio...

The objective of this paper is to evaluate the potential of Gaofen-2 (GF-2) high resolution multispectral sensor (MS) and panchromatic (PAN) imagery on water mapping. Difficulties of water mapping on high resolution data includes: 1) misclassification between water and shadows or other low-reflectance ground objects, which is mostly caused by the spectral similarity within the given band range;...

Paralogs of the widely prevalent phosphoglucomutase (PGM) protein called parafusin function in calcium (Ca2+)-mediated exocytosis across eukaryotes. In Toxoplasma gondii, the parafusin-related protein 1 (PRP1) has been associated with Ca2+-dependent microneme organelle secretion required for essential processes like host cell invasion and egress. Using reverse genetics, we observed PRP1 to be d...

BACKGROUND/OBJECTIVES Palestinian strains of L.tropica characterized by multilocus enzyme electrophoresis (MLEE) fall into two zymodemes, either MON-137 or MON-307. METHODOLOGY/PRINCIPLE FINDINGS Assays employing PCR and subsequent RFLP were applied to sequences found in the Hexokinase (HK) gene, an enzyme that is not used in MLEE, and the Phosphoglucomutase (PGM) gene, an enzyme that is used...
