Distortion free geometry based secret image sharing
, 2011 Blakley proposed a method to share a secret among a number of participants in 1979. His method uses the fact that a point (secret) in k-dimensional space is the intersection point of k hyperplanes.

Deep Underground Science and Engineering, EarlyView.This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Secret Image Hiding and Sharing Based on the (t, n)-Threshold
, 2012 [[abstract]]This study proposes a new secret image sharing method based on the (t, n)-threshold.The sharing method is completed through three main steps: (1) quantizing the secret image, (2) generating n shadows from the quantized image, and (3) sharing ...

Weighted modulated secret image sharing method
, 2012 [[abstract]]We present a novel hybrid method that includes a modulated scheme for reducing the distortion of the reconstructed image and a two-layered structure for grouping participants with different weights in a secret image sharing problem ...

Secret Image Sharing with Reversible Steganography
, 2010 [[abstract]]The significant essential of secret image sharing approaches is that the revealed content of the secret image must be lossless. Moreover, the distorted stego images can be reverted to the original cover image.

Deep Underground Science and Engineering, EarlyView.High atmospheric pressure (120 kPa) in deep underground counteracts humidity‐induced physiological stress in plants, stabilizing water balance and enhancing antioxidative defenses. This synergy boosts biomass despite elevated humidity, demonstrating sustainable deep underground agriculture potential under climate uncertainty.
