Advanced Materials, EarlyView.Photothermal nanodiamonds with quantum sensing capabilities generate lysosome‐confined hyperthermia, enabling simultaneous temperature and radical detection via diamond sensing. This localized thermal and oxidative stress drives pro‐inflammatory (M1) macrophage polarization, revealing a new strategy for precision immunomodulation through subcellular ...

On quasirecurrent manifolds [PDF]
Mathematica BohemicaWe introduce a type of Riemannian manifolds (namely, quasirecurrent manifold) and study its several geometric properties. Among others, we prove that the scalar curvature of such a manifold is constant, and that the manifold is Einstein under certain ...

Macrophages Mediate Mesoscale Brain Mechanical Homeostasis
Advanced Materials, EarlyView.We investigated the role of infiltrating immune cells in sculpting the developing brain. Using Brillouin microscopy and active microrheology, we found microglia actively maintain tissue viscoelasticity. Moreover, colony stimulating factor one receptor (CSF1R)‐driven stromal remodeling alters brain mechanics in vivo. These findings link immune activity,

Rigidity of Weak Einstein-Randers Spaces [PDF]
Sahand Communications in Mathematical AnalysisThe Randers metrics are popular metrics similar to the Riemannian metrics, frequently used in physical and geometric studies. The weak Einstein-Finsler metrics are a natural generalization of the Einstein-Finsler metrics.

On Submanifolds of $N(k)$-Quasi Einstein Manifolds with a Type of Semi-Symmetric Metric Connection
Universal Journal of Mathematics and Applications, 2020 In this study, we consider the $ N(k)- $quasi Einstein manifolds with respect to a type of semi-symmetric metric connection. We suppose that the generator of $ N(k)- $quasi-Einstein manifolds is parallel with respect to semi-symmetric metric connection

Advanced Materials Interfaces, EarlyView.The orientation and organization of an amphiphilic BOPHY dye in Langmuir monolayers are investigated using in situ XRR, GIXD, and MD simulations. Two condensed phases are identified: alkyl chains govern packing density, while chromophores remain locally ordered.

Einstein like -para Sasakian manifolds
Kuwait Journal of Science, 2013 Einstein like -para Sasakian manifolds are introduced. For an -para Sasakian manifold to be Einstein like, a necessary and sufficient condition in terms of its curvature tensor is obtained.

Boosting the Performance of Epitaxial Perovskite Microstructures by Surface Passivation
Advanced Optical Materials, EarlyView.Surface passivation is applied to epitaxial perovskite structures. Improvements are obtained in respect to luminescence intensity and decay time, as well in respect to photodetection and lasing. Highlight results include photoluminescence transients that are limited only by carrier diffusion and a record low laser threshold for microcrystal‐based ...

Construction of an A-manifold on a principal torus bundle
Annales Universitatis Paedagogicae Cracoviensis: Studia Mathematica, 2013 We construct a new example of an A-manifold, i.e. a Riemannian manifold with cyclic-parallel Ricci tensor. This condition can be viewed as a generalization of the Einstein condition.
