Background and Aim: The semantic evolution of a word over time is inevitable, indicating a social, political, religious or cultural process. Nurse is one of the words that has a significant presence in Persian literature texts and has been used in many different meanings such as slave, servan, maid, devotee, obedient, patient and preserver. The purpose of this study is to show its semantic ev...

this paper examines the semantic contribution of -?r and -andeh suffixes in persian based on lieber’s (2004) lexical semantic representation. this framework using six semantic features ([material], [dynamic], [location], [ieps] , [b] and [ci] and a principle called coordination principle studies the semantic contribution of lexical items including affixes and their functions in compounding, der...

Categories are not invariant. This paper attempts to explore the dynamic nature of semantic category, in particular, that of fashion language, based on the cognitive theory of Dawkins’ memetics, a new theory of cultural evolution. Semantic attributes of linguistic memes decrease or proliferate in replication and spreading, which involves a dynamic development of semantic category. More specific...

3D semantic labeling is a fundamental task in airborne laser scanning (ALS) point clouds processing. The complexity of observed scenes and the irregularity of point distributions make this task quite challenging. Existing methods rely on a large number of features for the LiDAR points and the interaction of neighboring points, but cannot exploit the potential of them. In this paper, a convoluti...

Background and Aims: Mesenchymal stem cells (MSCs) are a preferred cell source for the generation of hepatocyte-like cells in regenerative medicine. They can be isolated from different sources, including adipose tissues. The Raman spectroscopy approach was evaluated for quick and efficient identification of MSCs differentiation status and a broader perspective on cell differentiation. Material...

Among the synthetic polymers, poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) microbial polyester is one of the biocompatible and biodegradable copolymers in the nanomedicine scope. PHBV has key points and suitable properties to support cellular adhesion, proliferation and differentiation of nanofibers. Nanofibers are noticeably employed in order to enhance the performance of biomaterials,...

There are several differentiation methods for mesenchymal stem cells (MSCs) into hepatocyte-like cell. Investigators reported various hepatic differentiation protocols such as modifying culturing conditions or using various growth factors/cytokines. In this literature review, we compared different MSCs extraction and isolation protocols from Wharton’s jelly (WJ) and explored various MSCs differ...

The calculation of derivatives is ubiquitous in science and engineering. In thermodynamics, particular, state properties can be expressed as thermodynamic potentials. manual differentiation complex models tedious error-prone. this work, we revisit dual hyper-dual numbers for the exact show generalizations to higher order with respect vector quantities. methods described paper are accompanied by...

Jointly performing semantic and instance segmentation of 3D point cloud remains a challenging task. In this work, novel framework called joint semantic-instance via multi-scale Semantic Association Salient clustering Optimization was proposed to tackle problem. Inspired by the inherent correlation among objects in space, Multi-scale (MSA) module explore constructive effect context information f...
