Autonomous DRL-based energy efficient VM consolidation for cloud data centers

, 2022
The exponential data growth and demands for high computing resources lead to excessive resource use in cloud data centers, which cause an increase in energy consumption and high carbon emissions in the environment.

Light‐Programmed Localized Supersaturation Enables Ambient Aqueous Synthesis of Highly Crystalline Metal–Organic Frameworks

Advanced Materials, EarlyView.
In the proposed model, a photoinduced nanoreactor uses Cu2O self‐photooxidation to generate localized supersaturation. A metastable supersaturation state first forms a shell, creating a spatially confined environment that restricts reactant exchange; continued Cu release then drives the local environment toward a labile regime that favors predominantly

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

Advanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Purely Equatorial Lasing in Spherical Liquid Crystal Polymer Microlasers with Bipolar Refractive Index Profile

Advanced Optical Materials, EarlyView.
Spherical liquid crystal polymer microlasers with a bipolar configuration confine lasing to a single equatorial plane, allowing precise control over where the laser emission is generated. The anisotropic refractive index profile additionally lifts the energy degeneracy of azimuthal whispering gallery modes, which causes a characteristic splitting into ...

Software consolidation as an efficient energy and cost saving solution [PDF]

, 2016
Virtual machines (VM) are used in cloud computing environments to isolate different software. They also support live migration, and thus dynamic VM consolidation. This possibility can be used to reduce power consumption in the cloud.
