Imaging of Biphoton States: Fundamentals and Applications
Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Stability Analysis of Systems with Interval Time-Varying Delays via a New Integral Inequality
This paper focuses on delay-dependent stability analysis for systems with interval time-varying delays. Based on a new integral inequality and a generalized reciprocally convex combination matrix inequality, a new delay-dependent stability criterion is ...

Cuttlebone‐inspired metamaterials exploit a septum‐wall architecture to achieve excellent mechanical and functional properties. This review classifies existing designs into direct biomimetic, honeycomb‐type, and strut‐type architectures, summarizes governing design principles, and presents a decoupled design framework for interpreting multiphysical ...

Clean Up Behind You ‐ Novel Patterning Approach for Solid Immersion Lenses
A focused ion beam (FIB) milling strategy enables rapid fabrication of solid immersion lenses (SILs) with smooth, debris‐free surfaces eliminating the need for post‐processing. The optimized pattern improves efficiency and surface quality. SILs containing NV centers are also investigated, confirming the technique's suitability for quantum and photonic ...

A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

Does military spending affect inequality in South Africa? A revisit
Previous investigations on the military spending-inequality nexus (in South Africa) were underpinned by the assumption that military spending and inequality behaves in symmetric fashion and employed linear autoregressive distributed lag (ARDL) model in ...

Analysis of Relationship between Per Capita Income Growth, Household Debt and Income Inequality (Case Study: Iranian Provinces) [PDF]
After world recession in 2008, many papers focused on non-linear relationship between debt and growth. Based on traditional theories, a medium level of increase in debt can improve welfare and economic growth, but a high level of it damages the economy ...
