The cover image of this issue was designed by Prof. Rudra Pratap for the digital health initiative of IISc. The sequence of 1s and 0s represent the binary code of ASCII values of “Digital Hospital @ Indian Institute of Science, Bangalore” repeated a few times.

Coverpage Description: Waddington landscape displaying the ability of phenotypes to switch among one
another (phenotypic plasticity) under varying conditions.

The emerging landscape of a connected world. 5G and Beyond will be much more about enabling diverse services and applications than previous generations of cellular telephony. The picture is an imagination of the myriad applications that are possible when seamless and ubiquituous connectivity truly becomes a reality.

Hydrogen has a valency of one and it was assumed that it could make only one bond. Latimer and Rodebush, while analyzing the liquid water, boldly suggested that H atom from one water molecule could interact with the oxygen in a neighboring molecule forming another bond! While identifying hydrogen bond in water and later in DNA was easy, understanding it has been not so easy. It led to various descriptions of a hydrogen bond, comparable to the ancient parable from India on the description of an elephant by six blind men. In this issue, there are 16 articles and they discuss various aspects of a hydrogen bond shown in the cover image.

Computational Science and Engineering: Major Research/Impacting Topics

Description of the cover page: The cover page shows pattern-formation during a spinodal decomposition of binary alloy in 3D, two and three-phase cross-sections of three-dimensional directionally solidified microstructures, morphological instabilities during dendritic and two-phase colony formation and finally the break-up of a thin-film as a result of a mechanical instability. These are some of the mechanisms of microstructural evolution which have been modelled using the phase-field method, and a respective description of the different applicable models form a part of this review.

The cover page shows a topological non-trivial state which maintains its chirality depending on clockwise or anti-clockwise twist. Once there is an edge or transition from non-trivial to trivial state new type of phases or excitations emerge. This issue gives a preview of those emergent fields in mesoscopic physics.

"The cover page photo is a collection of images of the flows/flows infront of test models recorded using different flow diagnostic techniques. The central image is the top view of Laboratory for Hypersonic and Shock waves Research (LHSR) at IISc, actively involved in flow diagnostics related research".

The cover page celebrates design science and some of its major milestones.
