One of the most significant challenges in diagnosis brain cancer is efficient vivo imaging using nontoxic nanoprobes. Core–shell gold nanorod@MIL-88(Fe) nanostars are successfully constructed as triple-modality (computed tomography/magnetic-resonance imaging/photoacoustic imaging) nanoprobes that show low cytotoxicity, high contrast, penetration depth, and spatial resolution for accurate noninvasive gliomas. As a service to our authors readers, this journal provides supporting information...
We report on near-GeV electron beam generation from an all-optical cascaded laser wakefield accelerator (LWFA). Electron injection and acceleration are successfully separated controlled in different LWFA stages by employing two gas cells filled with a $\mathrm{He}/{\mathrm{O}}_{2}$ mixture pure He gas, respectively. Electrons Maxwellian spectrum, generated the first assisted ionization-induced injection, were seeded into second 3-mm-thick cell accelerated to be 0.8-GeV quasimonoenergetic...
To improve patient outcome and decrease overall health-care costs, highly sensitive precise detection of a tumor is required for its accurate diagnosis efficient therapy; however, this remains challenge when using conventional single mode imaging.

Abstract Settlement and metamorphosis of pediveliger larvae Mytilus coruscus in response to natural biofilms was investigated the laboratory. Pediveliger settled metamorphosed post-larval settlement increased with biofilm age. The activity positively correlated age, dry weight, bacterial density diatom density, but had no apparent relationship chlorophyll a concentration. change community composition corresponding age may explain differences age-dependent inducing activities biofilms, which...
We present a recent progress of the SG-II 5PW facility, which designed multi-petawatt ultrashort pulse laser based on optical parametric chirped-pulse amplification (OPCPA).

The effect of drive laser wavelength on the growth ablative Rayleigh–Taylor instability (ARTI) in inertial confinement fusion (ICF) is studied with two-dimensional numerical simulations. results show that plasma acceleration phase, shorter wavelengths lead to more efficient coupling between and kinetic energy implosion fluid. Under condition coupled fluid constant, ARTI rate decreases as moves toward extreme ultraviolet band, reaching its minimum value near λ = 65 nm, when continuously X-ray...
Theranostic tantalum oxide nanoparticles (TaOxNPs) of about 40 nm were successfully developed by conjugating functional molecules including polyethylene glycol (PEG), near-infrared (NIR) fluorescent dye, doxorubicin (DOX), and hyaluronic acid (HA) onto the surface (TaOx@Cy7-DOX-PEG-HA NPs) for actively targeting delivery, pH-responsive drug release, NIR fluorescence/X-ray CT bimodal imaging.

For fine-grained human perception tasks such as pose estimation and activity recognition, radar-based sensors show advantages over optical cameras in low-visibility, privacy-aware, wall-occlusive environments. Radar transmits radio frequency signals to irradiate the target of interest store information echo signals. One common approach is transform echoes into radar images extract features with convolutional neural networks. This article introduces RadarFormer, first method that...

Although they have been under development for years and are attracting a lot of attention, vision-based tactile sensors still common defects-the use such devices to infer the direction external forces is poorly investigated, operating frequency too low them be applied in practical scenarios. Moreover, discussion deformation elastomers used remains insufficient. This research focuses on analyzing thin elastic layer sensor by establishing simplified model, which cross-validated using finite...
