Abstract We propose a parametrization of the leading B-meson light-cone distribution amplitude (LCDA) in heavy-quark effective theory (HQET).In position space, it uses a conformal transformation that yields a systematic Taylor expansion and an integral bound, which enables control of the truncation error.Our parametrization further produces compact
A Dynamic Triple-Image Encryption Scheme Based on Chaos, S-Box and Image Compressing
To guarantee the security and high-efficiency of image transmission, a novel triple-image encryption scheme based on chaotic system, S-box and image compressing is proposed in this paper.Firstly, the combination process is performed by compressing three plain images to 25% and combining the compressed images with a stochastic matrix generated by th
Faecal helminth egg and oocyst counts of a small population of African lions (Panthera leo) in the southwestern Kalahari, Namibia : research communication
An endoparasite survey of a small pride of African lions (Panthera leo) was conducted at Intu Afrika Kalahari Game Reserve, southwestern Namibia, during winter and summer of 2003 and 2004, respectively.Overall, 23 fresh lion scats were collected opportunistically during fieldwork trials.A flotation technique was employed for the diagnosis of parasi
Syntactic and Semantic Aware Graph Convolutional Network for Aspect-Based Sentiment Analysis
In recent years, there has been a growing interest in utilizing dependency parsing with graph convolutional networks for aspect-based sentiment analysis.Dependency relations between words are used to construct graphs that Film FEP integrate syntactic information into deep learning frameworks.However, most existing methods fail to consider the impac
Fixation of Sacral Ala Fracture Using a Midfoot Mesh Plate as a Cannulated Screw Washer: A Case Report
Introduction: Sacral fractures are rare but are increasing in Coffee Table incidence among trauma patients.They are associated with a wide variety of complications, most commonly neurologic defects.Case Report: A 59-year old woman initially underwent open reduction internal fixation (ORIF) for a sacral fracture, after which the patient developed an
