To date, the 17th European Bioenergetics Conference (EBEC) in Freiburg, Germany (September 15-20, 2012) was the most exciting conference for the complex I (NADH-Q oxidoreductase) research field. A whole day of oral presentations was dedicated to complex I, including three plenary lectures and 11 symposium talks. In addition, 43 posters were dedicated to complex I projects. Here is a brief summary of an exciting paradigm shift from 'structure major' to 'structure plus function', clearly observed in the complex I research field.

Electric quadrupole traps are a leading technology for suspending charged objects ranging in size from single protons to atomic and molecular ions, and even to nano- and micron-sized bodies. If the levitated objects' charge distribution contains multipoles, the time-dependent trapping fields can significantly impact its rotational motion. Here, we experimentally observe the transition from librational motion to a regime where a microparticle rotates in sync with the trap drive.

We study image segmentation using spatiotemporal dynamics in a recurrent neural network where the state of each unit is given by a complex number. We show that this network generates sophisticated spatiotemporal dynamics that can effectively divide an image into groups according to a scene's structural characteristics. We then demonstrate a simple algorithm for object segmentation that generalizes across inputs ranging from simple geometric objects in grayscale images to natural images.

Microadditive manufacturing has revolutionized the production of complex, nano- to microscale components across various fields. This work investigates two-photon (2P) and three-photon (3P) fluorescence imaging, as well as third-harmonic generation (THG) microscopy, to examine periodic microarchitected lattice structures fabricated using multiphoton lithography (MPL). By immersing the structures in refractive index matching fluids, we demonstrate high-fidelity 3D reconstructions of both fluorescent structures using 2P and 3P microscopy as well as low-fluorescence structures using THG microscopy.

Superior to traditional multiplex photoelectrochemical (PEC) sensors, integrated multitarget assay on a single reconstructive electrode interface is promising in real-time detection through eliminating the need of specialized instrumentation and cumbersome interfacial modifications. Current interface reconstruction approaches including pH modulation and bioenzyme cleavage involve biohazardous and time-consuming operations, which cannot meet the demand for rapid, eco-friendly, and portable detection, which are detrimental to the development of multiplex PEC sensors toward portability. Herein, we report a pioneer work on IR-driven "four-to-one" multisignal conditioning to facile reconfigure electrode interface for multitarget detection via photoelectrochemical/photothermal dual mode.

Depression is a common and complex neuropsychiatric disorder affecting people of all ages worldwide, associated with high rates of relapse and disability. Neohesperidin (NEO) is a dietary flavonoid with applications in therapeutics; however, its effects on depressive-like behavior remain unknown. Here, we evaluated the effects of NEO on depressive-like behavior induced by chronic and unpredictable mild stress (CUMS).
