[7]Helicene‐Appended o ‐Carboranes: Sign‐Changing Circularly Polarized Luminescence Based on Dual‐Emissive Properties and Its Temperature Dependency
Sign Up to like & getrecommendations! Published in 2025 at "Advanced Optical Materials"
DOI: 10.1002/adom.202502647
Abstract: Circularly polarized luminescence (CPL) attracts tremendous attention owing to their applicability for the next‐generation optoelectronics. Precise control over CPL sign as well as its stimuli‐responsiveness is one of the next goals, especially for developing solid‐state… read more here.

Integrating multiple sign types to improve occupancy estimation for inconspicuous species
Sign Up to like & getrecommendations! Published in 2023 at "Ecology and Evolution"
DOI: 10.1002/ece3.10019
Abstract: Abstract Standard occupancy models enable unbiased estimation of occupancy by accounting for observation errors such as missed detections (false negatives) and, less commonly, incorrect detections (false positives). Occupancy models are fitted to data from repeated… read more here.

DOI: 10.1002/jmri.29245
Abstract: Nigrosome 1 (N1), the largest nigrosome region in the ventrolateral area of the substantia nigra pars compacta, is identifiable by the “N1 sign” in long echo time gradient echo MRI. The N1 sign's absence is… read more here.

DOI: 10.1002/mdc3.13422
Abstract: The helicopter sign is a pathognomonic sign of orthostatic tremor constituting the auditory correlate of the characteristic high frequency (13 to 18 Hz) tremor in the legs upon standing. 1 The auditory correlate of low… read more here.

DOI: 10.1002/mdc3.13596
Abstract: When the hot cross bun (HCB) was created in the 12th century, little did its makers know that the buns’ rather innocuous existence would extend far beyond the realms of the culinary world and that… read more here.

DOI: 10.1007/s00062-020-00985-0
Abstract: Despite advancement in mechanical thrombectomy (MT) techniques, 10–30% of MT for large vessel occlusions (LVO) are unsuccessful. Current prediction models fail to address the association between patient-specific factors and reperfusion. We aimed to evaluate objective,… read more here.

DOI: 10.1007/s00213-021-05887-8
Abstract: RATIONALE Reward-associated cues can promote maladaptive behavior, including risky decision-making in a gambling setting. A propensity for sign tracking over goal tracking-i.e., interaction with a reward-predictive cue rather than the site of reward-demonstrates an individual's… read more here.
