Magnetically Responsive Piezoelectric Nanocapacitors Enhance Neural Recovery Following Spinal Cord Injury via Targeted Spinal Magnetic Stimulation

Advanced Science, Volume 13, Issue 13, 3 March 2026.
This study presents a novel “in vivo–in vitro” therapeutic strategy for spinal cord injury by leveraging magnetically responsive piezoelectric nanomaterials. These nanomaterials enable targeted delivery of localized electrical stimulation at the injury site through noninvasive external magnetic actuation, thereby promoting axonal regeneration and ...

Optical photometry of Sco X-2

Astronomy & Astrophysics, 1997
We present optical photometry of the galactic bulge low-mass X-ray binary GX 349+2 (Sco X-2) obtained in July 1993 and March 1996. Short-term variations up to one magnitude are present on time scales of a few hours, which are related to the known X-ray behaviour of the source.

The Bochum Survey of the Southern Galactic Disk: III. Complete Data Release

Astronomische Nachrichten, Volume 347, Issue 3, March 2026.
ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°$$ {6}^{{}^{\circ}} $$‐wide stripe in the southern Galactic disk with simultaneous observations in r′$$ {r}^{\prime } $$ and i′$$ {i}^{\prime } $$ (7m≲r′,i′≲18m$$ {7}^{\mathrm{m}}\lesssim {r}^{\prime },{i}^{\prime}\lesssim {18}^{\mathrm{m}} $$) from September ...

Perceived Saturation in Normal and Red–Green Color‐Deficient Observers

Color Research &Application, Volume 51, Issue 2, March/April 2026.
Results in this study indicate that perceived saturation of protan (P) and deutan (D) observers is lower than that of color normal (N) observers as shown in the figures. Horizontal axis denotes the stimulus pair with the same hue but different chroma.

Experimental Study of PWM-Controlled Emission From a Large-Aperture VCSEL

IEEE Photonics Journal
This study demonstrates the use of pulse-width modulation (PWM) for mode selection in a large-aperture vertical-cavity surface-emitting laser (VCSEL). Experimental results reveal that driving the device with 1 kHz PWM pulses maintains a stable far-field ...

30 Doradus - Ultraviolet and optical stellar photometry

The Astrophysical Journal, 1993
Ultraviolet Imaging Telescope (UIT) UV magnitudes in four bands, together with optical B magnitudes, are presented for up to 314 early-type stars located in a 9.7 x 9.7 arcmin field centered on R136. The magnitudes have an rms uncertainty estimated at 0.10 mag from a comparison between the UIT magnitudes and the IUE spectra.

Human Eye Visualization With an Attention Mechanism: Enhancing Flower Detection and Classification With Visual Attention and Photometric Principles Inspired by Human Vision

Engineering Reports, Volume 8, Issue 3, March 2026.
The graphical abstract illustrates a flower classification model relying on the human visual system. The model captures images, simulates visual attention and photometric perception, extracts features of shape and color, and classifies flowers by using an optimized neural network that enhances recognition accuracy by mimicking the human eye's focusing ...
