Providencia stuartii is a highly social pathogen responsible for nosocomial chronic urinary tract infections. The bacterium indeed forms floating communities of cells (FCC) besides and prior-to canonical surface-attached biofilms (SAB). Within P. stu

Reversibly photoswitchable fluorescent proteins are essential markers for advanced biological imaging, and optimization of their photophysical properties underlies improved performance and novel applications. Here we establish a link between photoswi

In this study, deep traps in multiple-finger normally-off AlGaN/GaN metal-insulator-semiconductor high-electron mobility transistors (MIS-HEMTs) were identified. The localization of these traps has been established by a comparative study using capaci

The localization of deep traps in normally-off AlGaN/GaN metal-oxide-semiconductor channel high-electron mobility transistors has been established by means of capacitance and current deep level transient spectroscopies (DLTS). Electrical simulations

We report that porins, the main gateway for hydrophilic nutrients and ions into bacterial cells, assemble face-to-face in crystals, yielding dimers of trimers (DOTs). Further investigation suggests that DOTs could support cell-to-cell contact in the
