Network reconfiguration is an important mechanism for network operators to optimize performance and optical flow transfer. It concerns unicast multicast connections. Multicast connections are required meet the bandwidth requirements of applications, such as Internet Protocol-based TeleVision (IPTV), distance learning, telemedicine. In networks, a connection made possible by creation tree-shaped...

We develop a finite-state transducer for translating unranked trees into general graphs. This work is motivated by recent progress in semantic parsing natural language, where sentences are first mapped tree-shaped syntactic representations, and then these translated graph representations. investigate formal properties of our tree-to-graph transducers polynomial time algorithm weighted language ...

In this paper X-ray computed tomography imaging data is used to perform nondestructive tree-ring width measurements in three archaeological wooden samples. Measurements of the curvilinear-tree-ring widths are performed using two approaches: firstly, measuring manually distance between points on consecutive tree-rings along orthogonal radii and, secondly, a recently proposed computational approa...

Few studies have quantified regional variation in tree mortality, or explored whether species compositional changes or within-species variation are responsible for regional patterns, despite the fact that mortality has direct effects on the dynamics of woody biomass, species composition, stand structure, wood production and forest response to climate change. Using bayesian analysis of over 430,...

CASE REPORT A 23 years old male with an unremarkable past medical history suffered an injury with a branch of a lemon tree in the right eye two days prior to presentation. The slit-lamp examination showed a central corneal erosion with a white tree-shaped stromal infiltrate and Tyndall +/++ in anterior chamber. Cultivation of corneal scraping was positive for Colletotrichum spp. The patient res...

In this paper we show how a theorem in plane geometry can be converted into an O(n log n) algorithm for decomposing a polygon into star-shaped subsets. The computational efficiency or this new decomposition contrasts with the heavy computational burden of existing methods. 1.0 Introduction The decomposition of a simple planar polygon into simpler components plays an important role in syntactic ...

Tree-shaped molecules consisting of octa-p-phenylene as a stem segment and oligoether dendrons as a flexible head were synthesized and characterized. The molecular tree based on a small flexible head self-assembles into a lamellar structure, whereas the molecule based on a larger headgroup self-assembles into a discrete heptameric bundle that organizes into a 3-D primitive orthorhombic supercry...

PuMPE is a comprehensive resource that provides integrated information on metabolome of bacterial systems. The genome data is annotated to infer metabolic pathways using in-house tools and web-based sources. PuMPE introduces a novel aspect of metabolic categorization. It is the first resource to provide metabolome-based tree computed by comparing metabolome between bacteria. PuMPE has metabolic...

Large uncertainties characterize forest development under global climate change. Although recent studies have found widespread increased tree mortality, the patterns and processes associated with tree death remain poorly understood, thus restricting accurate mortality predictions. Yet, projections of future forest dynamics depend critically on robust mortality models, preferably based on empiri...
