Analytically the effect of polarization dependent loss on a high speed fiber optic communication link has been investigated. significant co-relation between them and their various combinations produces different effects on the system behavior which has been together to observe the attenuation effect induced by PDL in a link containing multiple PDL elements. It is found that in the presence of P...

OBJECTIVE To develop an index that assesses the degree of adherence to existing diet-lifestyle recommendations for preschoolers (Preschoolers Diet-Lifestyle Index (PDL-Index)) and to investigate its association with obesity. DESIGN The PDL-Index was constructed using eleven components (i.e. questions regarding the frequency of consumption of selected foods/food groups, time spent on televisio...

A logical framework is presented for representing and reasoning about nondeterministic programs that may not terminate. We propose a logic PDL(; ;, ||, d(∗)) which is an extension of dynamic logic such that the program constructors related to demonic operations are introduced in its language. A complete and sound Hilbert-style proof system is given and it is shown that PDL(; ;, ||, d(∗)) is dec...

Widely used descriptions and relationships for birefringence and polarization-dependent loss (PDL), developed primarily for ultraviolet-induced long-period fiber gratings (LPFGs) written in optical fiber, can be invalid for other types of LPFG. The understanding of PDL is expanded to include LPFGs with birefringence in the core only, in the cladding only, and in both the core and the cladding. ...

We consider variants o f propositional dynamic logic (PDL) augmented with the converse construct. Intuitively, the converse a of a program a is a programs whose semantics is to run a backwards. While PDL consists o f assertions about weakest preconditions, the converse construct enable us to make assertions about strongest postconditions. We investigate the interaction of converse with two cons...

Programmed death ligands (PDLs) are immune-regulatory molecules that are frequently affected by chromosomal alterations in B-cell lymphomas. Although PDL copy-number variations are well characterized, a detailed and comprehensive analysis of structural rearrangements (SRs) and associated phenotypic consequences is largely lacking. Here, we used oligonucleotide capture sequencing of 67 formalin-...

Mesenchymal stem cells (MSCs) are involved in anti-inflammatory events and tissue repair; these functions are activated by their migration or homing to inflammatory tissues in response to various chemokines. However, the mechanism by which MSCs interact with other cell types in inflammatory tissue remains unclear. We investigated the role of periodontal ligament fibroblasts (PDL-Fs) in regulati...

We endow prioritised default logic (PDL) with argumentation semantics using the ASPIC framework for structured argumentation, and prove that the conclusions of the justified arguments are exactly the prioritised default extensions. Argumentation semantics for PDL will allow for the application of argument game proof theories to the process of inference in PDL, making the reasons for accepting a...

We endow Brewka’s prioritised default logic (PDL) with argumentation semantics using the ASPIC framework for structured argumentation. We prove that the conclusions of the justified arguments correspond to the prioritised default extensions in a normatively rational manner. Argumentation semantics for PDL will allow for the application of argument game proof theories to the process of inference...

Collagen XII has been postulated to organize the extracellular matrix (ECM) architecture of dense connective tissues such as the periodontal ligament (PDL) and skin. The objective of this study was to test this hypothesis in transgenic mice carrying a dominant interference mutation of collagen XII. The truncated alpha1(XII) collagen minigene construct MXIINC3(-), driven by the mouse alpha2(I) c...
