iran is one of the countries facing the most severe farmland fragmentation (ff) in rural areas and farmland consolidation (fc) is generally regarded as being a suitable instrument to solve this problem . a case study in the central area of iran was conducted to explore landholder's attitudes towards issues related to ff and fc. randomized stratified sampling frame was used to select 146 landhol...

the present paper investigates the influence of stabilization with cement, peat ash, and silica sand on permeability coefficient (kv) of compacted clay, using a novel approach to stabilize the clay with peat ash as a supplementary material of cement in the compacted and stabilized soil. in order to assess the mentioned influence, test specimens of both untreated and stabilized soil have been te...

OBJECTIVE There is controversy regarding the significance of radiological consolidation in the context of COPD exacerbation (eCOPD). While some studies into eCOPD exclude these cases, consolidation is a common feature of eCOPD admissions in real practice. This study aims to address the question of whether consolidation in eCOPD is a distinct clinical phenotype with implications for management d...

We studied the interaction between glucocorticoid (GC) level and sleep/wake state during memory consolidation. Recent research has accumulated evidence that sleep supports memory consolidation in a unique physiological process, qualitatively distinct from consolidation occurring during wakefulness. This appears particularly true for memories that rely on the hippocampus, a region with abundant ...

Digital watermarking has been recently proposed as the mean for copyright protection of multimedia data. This paper rst discusses some scenarios in which many current watermarking schemes fail to resolve the rightful ownership of an image. We then identify the key problems and discuss some crucial requirements for a valid invisible watermark detection. In particular , we argue that, for the par...

A subset S of vertices in a graph G is said to be an independent set of G if each edge in the graph has at most one endpoint in S and a set W ( V is said to be a resolving set of G, if the vertices in G have distinct representations with respect to W. A resolving set W is said to be an independent resolving set, or an ir-set, if it is both resolving and independent. The minimum cardinality of W...

The aim of this paper is to treat background (non-focus) elements as anaphoric, i.e. as objects which are formally subject to the same conditions which hold for other anaphora. The idea that backgrounds are anaphoric is inherent in many approaches to information structure, but they are rarely treated as such formally. I will discuss two problems which seem to challenge a strict anaphoricity app...
