Gaspelin and Luck describe the signal suppression hypothesis, which proposes that attentional suppression prevents the capture of visual attention by salient distractors. We will discuss several problems with this proposal. On a theoretical level, we will argue that attentional suppression is a dispensable mechanism. Most effects of attentional suppression can be easily explained by reduced target expectancy at the distractor location. On an empirical level, we will argue that electrophysiological evidence for attentional suppression is spurious because, in key conditions, the most likely reflects idiosyncratic scan paths.

Photocatalytic technology for removing organic dye pollutants has gained considerable attention because of its ability to harness abundant solar energy without requiring additional chemical reagents. In this context, YF spheres doped with Yb, Er, Tm (YF) are synthesized using a hydrothermal method and are subsequently coated with a layer of graphitic carbon nitride (g-CN) with Au nanoparticles (NPs) adsorbed onto the surface to create a core-shell structure, designated as YF: Yb, Er, Tm@CN-Au (abbreviated as YF@CN-Au). The core-shell composites demonstrate remarkable stability, broadband absorption, and exceptional photocatalytic activity across the ultraviolet (UV) to near-infrared (NIR) spectral range.

Two-dimensional lead iodide perovskites have attracted significant attention for their potential applications in optoelectronic and photonic devices due to their tunable excitonic properties. The choice of organic spacer cations significantly influences the light emission and exciton transport properties of these materials, which are vital for their device performance. In this Perspective, we discuss the impact of spacer cations on lattice dynamics and exciton-phonon coupling, focusing on three representative 2D lead iodide perovskites that exhibit distinct types of structural distortions.

The bioartificial pancreas, composed of a semi-permeable hydrogel encapsulating insulin-secreting cells, has attracted attention as a treatment for type 1 diabetes. In this study, we developed phospholipid polymer-modified alginate hydrogel beads that encapsulated spheroids of the pancreatic beta cell line MIN6. The hydrogel beads were composed of methacrylated alginic acid, which enabled both ionic and covalent cross-linking, resulting in a hydrogel that was more stable than conventional alginate hydrogels.

Background: We report a successful wound treatment of a chronic ulcer with bone exposure using a somehow forgotten technique of creating burr holes into the bone. Most clinics would promote flap surgery to cover wounds with bone exposure, however, in some cases invasive surgery is not mandatory. We bring up an alternative treatment for such cases.

Transcranial focused ultrasound (tFUS) has been gaining increased attention as a non-invasive modality for treating brain diseases. However, accurately focusing on brain structures remains a challenge as the ultrasound is severely distorted by the presence of the skull. In this article, we propose a promising distortion correction method based on spherical wave expansions.
