Block-based progressive visual secret sharing
, 2013 Block-based progressive visual secret sharing (BPVSS) is an encryption technique that utilizes the human visual system to recover a secret image. The recovery method is based on building up different image blocks step by step.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Enhancing oil recovery (EOR) in mature reservoirs is hindered by high interfacial tension (IFT) and oil‐wet rock formations, especially under harsh, high‐salinity conditions. This study aims to overcome these limitations by synthesizing a novel carbon nanotube nanocomposite covalently grafted with polyethylenimine and non‐covalently ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny
The Anatomical Record, EarlyView.Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Secret Image Sharing Based on Encrypted Pixels
IEEE Access, 2018 The well-known Thien and Lin's (k, n) secret image sharing (SIS) scheme and its extended versions are threshold schemes, in which a secret image is shared among n shadow images and it can be recovered from any k shadow images.

Image visualization encryption algorithm based on Shamir threshold secret key sharing
网络与信息安全学报, 2018 An image visualization encryption algorithm with authentication function by using Shamir scheme was proposed.The main idea of this algorithm is to obtain the data by segmenting the binary secret image into blocks.Then,Shamir scheme was used to obtain the

British Educational Research Journal, EarlyView.Abstract This article examines how national education in Hong Kong functions as a contested arena in which state and non‐state actors struggle over the meaning of citizenship, identity and schooling. Using inductive frame analysis of 319 news articles (2020–2025) from five Chinese‐ and English‐language outlets, it identifies diagnostic, prognostic and ...

Flourishing through adventure learning: A (semi)cautionary tale
British Educational Research Journal, EarlyView.Abstract Studies suggest that adventure learning can develop children's cognitive skills and promote social and emotional learning. However, evidence is needed as to whether the design of adventure learning—school‐based or external/residential—plays a role in that development/promotion, and whether learning gains are maintained.
