Summary: This study analyzed the labels of 444 sunscreen formulations to uncover the characteristics and main trends of commercial sunscreens. Avobenzone, octocrylene, and bis-ethylhexyloxyphenol methoxyphenyl triazine were the most frequently used UV filters. Emulsified preparations and sprays were the preferred forms, and inorganic filters were more commonly used in children's sunscreens. The usage of certain UV filters decreased while there was an increasing tendency towards the use of titanium oxide.

Summary: Multilabel data consists of instances associated with multiple binary target variables. The primary task is multilabel classification, which aims to divide the target variables into relevant and irrelevant ones for a given instance. Other tasks involve ranking the target variables from the most to the least relevant or outputting a full joint distribution for all possible values of the binary targets.

Summary: The design of the Brazilian power market was based on the characteristics of the system in the 1990s, but some of the assumptions made for the regulatory framework are no longer valid. Failing to adapt the regulatory framework to the current system and economic reality could negatively impact the market signals and long-term sustainability. Despite the consensus on the need for modernization, there are concerns about the specific changes to be implemented.

Summary: The demand for eco-friendly alternatives for food packaging is increasing due to the negative impact of single-use plastics on the environment. Bioplastics, which are partly or entirely produced from renewable sources, have the potential to be a sustainable solution. However, their market adoption faces challenges in terms of regulations, consumer perception, and technological advancements.

Summary: The development of fast, reliable, cost-effective, and small biosensing devices is crucial for environmental pollution monitoring. This review discusses the latest trends in using biosensors to detect environmental contaminants. Different types of biosensors, including enzyme, whole cell, antibody, aptamer, DNA-based biosensors, and biomimetic sensors, are discussed, highlighting their applicability and construction characteristics. Various detection principles, such as amperometry, conductometry, and luminescence, are used in biosensor design, each with its specific selectivity and detection limits. Mimetic biosensors are gaining attention due to their advantages over classical ones. Further studies are needed for the development of robust biosensing devices capable of detecting pollutants from complex matrices without prior sample preparation.

Summary: Temporal metamaterials are artificial materials with electromagnetic properties that change over time, allowing for the realization of non-homogeneous temporal media or stepwise transitions. By modeling wave propagation through a generalized temporal multilayer structure, higher-order transfer functions can be synthesized, enabling the design of novel electromagnetic and optical devices with tailored scattering responses. This approach leverages the temporal dimension instead of the spatial dimension typically used in optical and electromagnetic multilayered structures.

Summary: In this Letter, a rainbow-like scattering process is reported at the interface of a boundary-induced temporal metamaterial realized by instantaneously opening the boundary conditions of a parallel plate waveguide. By changing the conductivity of one of the metallic plates, an equivalent temporal interface between two different media is created, and the monochromatic wave propagating into the waveguide gets scattered into a polychromatic rainbow in free space. The relationships between the waveguide mode and the raising rainbow are derived, and the underlying physics is applied to control the temporal rainbow by design.
