Enhancement of Low Contrast Images Based on Effective Space Combined with Pixel Learning
Images captured in bad conditions often suffer from low contrast. In this paper, we proposed a simple, but efficient linear restoration model to enhance the low contrast images.

Long duration underwater glider dataset: Indian Ocean from Perth, Australia to Mirissa, Sri Lanka
This data was collected using an underwater research vehicle, Slocum glider. The glider is an autonomous robot that is able to measure several water properties from surface to 1000 m depth. The duration of missions for underwater gliders are on the order

From Waste to Value: Conversion of Calcium Sulfate to Vaterite via Carbon Capture and Storage
This study introduces a new concept for carbon management that relies on the carbonation of industrial gypsum waste and yields phase‐pure vaterite at ambient conditions without any additives. The obtained vaterite is further shown to be a reactive material that develops compressive strength in aqueous suspensions like conventional cements.

Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.
