A Central Charge for sub-AdS Holography Open
We synthesize and sharpen various observations about sub-AdS holography in the literature to associate a central charge to sub-AdS scales of AdS x $X$ geometries. A key ingredient in our proposal is the idea that the AdS length is the leng…

A bstract Defining finite entanglement entropy for a subregion in quantum field theory requires the introduction of two logically independent scales: an IR scale that controls the size of the subregion, and a UV cut-off. In AdS/CFT, the IR…

Recipes for mixing vortices in a microchannel using electric field Open
Application of an electric field on the pressure-driven flow of a fluid inside a microchannel can create mixing vortices. The Coulombic force at electrode–fluid interface generates the additional stress to engender the instability. While t…

Coupled instability modes at a solvent/non-solvent interface to decorate cellulose acetate flowers Open
Dispensing a water drop on the thin film of a solution composed of cellulose acetate (CA) in dimethyl formamide (DMF) forms a thin and porous CA layer at the water–DMF interface. While a denser water drop on a rarer CA–DMF film manifests a…

From Atoms to Cells: Multiscale Modeling of LiNi<sub><i>x</i></sub>Mn<sub><i>y</i></sub>Co<sub><i>z</i></sub>O<sub>2</sub> Cathodes for Li-Ion Batteries Open
First-generation cathodes for commercial lithium-ion batteries are based on layered transition-metal oxides. Research on ternary compounds, such as LiCoO2, evolved into mixed-metal systems, notably Li(Ni,Mn,Co)O2 (NMCs), which allows signi…

A Shrinking-Core Model for the Degradation of High-Nickel Cathodes (NMC811) in Li-Ion Batteries: Passivation Layer Growth and Oxygen Evolution Open
A degradation model for high-nickel positive electrode materials that undergo a structural reorganisation involving oxygen loss and the formation of a disordered (spinel or rock-salt structure) passivation layer is presented for the first …

Lithium ion battery degradation: what you need to know Open
The expansion of lithium-ion batteries from consumer electronics to larger-scale transport and energy storage applications has made understanding the many mechanisms responsible for battery degradation increasingly important.

Experiences of intramedullary fixation of displaced clavicle fractures in young adults Open
Background: Incidence of fracture shaft of clavicle is increasing in young population due to increase incidence of road traffic accident. Conventionally plate and screw fixation has been the choice, but to avoid complications like soft tis…
