The restoration of planar cell polarity is an essential but poorly understood step toward physiological recovery during sensory-organ regeneration. Investigating this issue in the lateral line of the zebrafish, we found that hair cells regenerate in pairs along a single axis established by the restricted localization and oriented division of their progenitors. By analyzing mutants lacking the p...

The internet has become a major tool for communication, training, fundraising, media operations, and recruitment, and these processes often use web forums. This paper presents a model that was built using SentiWordNet, WordNet and NLTK to analyze selected web forums that included radical content. The approaches of the model measure and identify sentiment polarity and affect the intensity of tha...

The analysis of song lyrics can provide important meta-information about a song, such as its genre, emotion, and theme; however, obtaining this information can be difficult. Classifying a song based solely on its lyrics can be challenging for a variety of reasons, and as yet no single algorithm results in highly accurate classifications. In this paper, we examine why the task of classification ...

Panacis Japonici Rhizoma (Zhu-Jie-Shen in Chinese), the root of P. japonicus C.A. Mey., is commonly used in traditional Chinese Medicine. Saponins are the major bioactive compounds in this herb. The similarity of polarity and structure of the natural products in herb caused the difficulty of purification and resulted in the shortage and high cost of the reference compounds, which has greatly hi...

Planarians are capable of profound regenerative feats dependent upon a population of self-renewing adult stem cells called neoblasts. The key features of neoblasts are their capacity for indefinite self-renewal, their totipotency and the ability of their progeny to interpret differentiation and polarity signals and correctly replace lost structures after tissue damage. Regeneration in planarian...

In order to determine the influence of the nerve cord on the polarity of the blastema regeneration in Dugesia japonica, three groups of isolated body fragments with the reversed ventral nerve cord were prepared; 1) fragments with one nerve cord intact and the other rotated; 2) fragments with only one nerve cord reversed; 3) fragments with three nerve cords which consist of two intact nerve cord...

Sentiment Analysis is a natural language processing task that extracts sentiment from various text forms and classifies them according to positive, negative or neutral polarity. It analyzes emotions, feelings, and the attitude of a speaker or a writer towards a context. This paper gives comparative study of various sentiment classification techniques and also discusses in detail two main catego...

Ceratodon protoplasts regenerate by polar outgrowth to form cell filaments. The kinetics of regeneration show that some cellular event has to be completed before regeneration can be initiated. The development of the regeneration axis is strongly influenced by light, with axis alignment and axis polarity being fixed independently. We define axis alignment as the relationship of the regeneration ...

Monotonicity is considered to be one of the key properties of languages both in logic and linguistics. In model theory it contributes to definability (see e.g. Väänänen and Westerståhl, 2002), in linguistics it is used, among other applications, to explain the phenomenon of negative polarity items (see e.g. Ladusaw, 1979). There are also strong links between monotonicity and learnability (see e...

Regeneration requires specification of the identity of new tissues to be made. Whether this process relies only on intrinsic regulative properties of regenerating tissues or whether wound signaling provides input into tissue repatterning is not known. The head-versus-tail regeneration polarity decision in planarians, which requires Wnt signaling, provides a paradigm to study the process of tiss...
