Summary: Invisibility cloaks are a significant development in the field of metamaterials. While most efforts have been focused on improving the effectiveness of cloaks, little attention has been paid to the development of efficient techniques for detecting invisibility devices. This study proposes a different approach using diffraction tomography to enhance efficiency in detecting and obtaining images of invisibility cloaks, leading to improved sensitivity and potential application in sound cloaks.

Summary: This study experimentally demonstrated the control of light transmission through a slab of plasmonic liquid metacrystal by an external electric field. The induced macroscopic anisotropy caused polarization-dependent suppression of transmission at resonant frequencies, indicating selective plasmon excitation based on the orientation of meta-atoms with respect to the electromagnetic wave polarization. Analyzed theoretically from first principles, the results were compared with experimental data.

Summary: The study examines the plasma oscillation effect on coherent radio emission of fast radio bursts (FRBs) and concludes that the plasma suppression effect can be ignored for realistic FRB emission models. Plasma density and parallel electric fields play crucial roles in determining the power of coherent emission by bunches.

Summary: A theoretical model for a dynamic Moire grating capable of producing improved slow and stopped light performance was investigated. By varying coupling strength in time, the Moire grating can significantly reduce group velocity in the slow light resonance while maintaining a wide bandwidth. This dynamic Moire grating could potentially realize bandwidth modulation and be implemented using an electro-optic grating with a quasistatic electric field in a poled chi((2)) nonlinear medium.

Summary: In this study, it was found that the photonic properties in plant chloroplasts can be adjusted to enhance light absorption efficiency under different light conditions, mainly due to intrinsic nanophotonic properties within the chloroplasts. Different types of chloroplasts exhibit varying photonic effects as light intensity changes, indicating a significant impact of dynamic morphological changes on the optical properties of plants.

Summary: Cisplatin is one of the oldest chemotherapeutic agents and has been used to treat various types of cancer. However, tumor cells often develop resistance mechanisms, limiting the effectiveness of cisplatin treatment. Extensive molecular and genetic profiling of patients is needed to identify individuals who can benefit from cisplatin therapy, and combining it with targeted therapies may improve treatment outcomes.

Summary: This study demonstrates the precise control of light-matter interaction through plasmonic resonances empowered by bound states in the continuum (BICs). By exploiting BICs in the parameter space, sharp resonances with ultra-weak angular dispersion effect and polarization-independent performance are achieved on symmetric plasmonic metasurfaces. These results provide a way to achieve efficient near-field enhancement using focused light produced by high numerical aperture objectives.

Summary: This article evaluates the meaning, appropriate usage, and misusage of the terms oxidative stress, oxidative eustress, and oxidative distress. It reveals that oxidative stress and oxidative damage are often incorrectly used as synonyms. The term eustress, intended to signify good stress, is also found unsuitable for indicating signaling by reactive molecules that can have variable effects. The defined oxidative distress is identified as oxidative damage rather than oxidative stress. Additionally, damaging oxidations and signaling oxidant events, both positive and negative, can coexist in different locations within a cell, tissue, or body. The measurement of oxidant events in body fluids or tissue samples can only reflect the combined effects of non-separable events, sometimes with opposite effects. Officially approved therapies to prevent or cure oxidative stress or oxidative damage are currently lacking.

Summary: This paper comprehensively reviews several general methods and analytical tools for causality evaluation of photonic materials. The authors collect a set of various distributional theorems as the distributional version of the Titchmarsh theorem, allowing for evaluation of causality in complicated electromagnetic systems. They also correct existing material models using distribution theory to obtain their causal formulations. In addition to the Kramers-Kronig relations, four further methods are overviewed for assessing causality of given dispersion relations. These methodologies should be useful for scientists and engineers analyzing causality problems in electrodynamics and optics, particularly with regard to photonic materials when mathematical distributions are involved.

Summary: The ray dynamics of optical cavities exhibit bifurcation points, where ray trajectories switch abruptly between stable and unstable. Experimental results show that a slight deviation from these bifurcation points dramatically changes the laser performance. By using a near-planar cavity with concave mirrors, the number of transverse lasing modes increases drastically, leading to improved stability in spatiotemporal lasing dynamics.
