A Molecularly Defined Midbrain Circuit Mechanism for Sound‐Driven Defensive Behavior and Anxiety
Advanced Science, EarlyView.Schematic diagram showing the Cbln2+ ICx–dPAG circuit for sound‐driven defensive and anxiety‐like behaviors. ABSTRACT The innate defense behaviors in response to threatening sounds play a fundamental role in survival. However, the neural circuits that detect threat‐relevant auditory cues and transform them into defensive behaviors remain poorly defined.

An approach for automatic identification of fundamental and additional sounds from cardiac sounds recordings. [PDF]
, 2019 This paper presents an approach for automatic segmentation of cardiac events from non-invasive sounds recordings, without the need of having an auxiliary signal reference.

Advanced Science, EarlyView.Bioengineered stroma‐camouflaged nanovesicles (AM@UIO‐BMS/DOX) convert the immunosuppressive tumor niche into an immunoresponsive milieu by disrupting the IDO1/CD276 circuit. Anti‐CD276 membrane camouflage guides tumor accumulation and deep penetration, enabling controlled co‐delivery of DOX and the IDO1 inhibitor BMS‐986205.

HEART SOUND LOCALIZATION AND REDUCTION IN TRACHEAL SOUNDS BY GABOR TIME-FREQUENCY MASKING
Electrica, 2017 Respiratory sounds, i.e. tracheal and lung sounds, have been of great interest due to their diagnostic values as well as the potential of their use in the estimation of the respiratory dynamics (mainly airflow).

Optical Access to Dark Excitons Via Spin–Phonon Fano Interference
Advanced Science, EarlyView.Dark excitons in quantum dots neither absorb nor emit light and stay hidden from optical spectroscopy. Quantum interference now reveals them: light scattered by acoustic phonons interferes with a phonon‐assisted spin flip between bright and dark exciton, carving a Fano dip into the spectrum whose position gives the bright–dark splitting. Magnetic field,

Simplicity Based Gating of Heart Sounds
, 2008 Segmentation of the phonocardiogram (PCG) into its major sound components is the first step in automated diagnosis of cardiac abnormalities. Almost all the existing PCG segmentation algorithms are based upon amplitude or frequency characteristics, of the

Habitat‐Specific Design Strategies for Untethered Soft Robots
Advanced Science, EarlyView.Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...

Advanced Science, EarlyView.Salivary citrate deficiency in early‐stage Sjögren's syndrome accompanies impaired dentin remineralization despite preserved salivary flow and mineral availability. Matched‐ion experiments reveal disrupted mineral organization and reduced dentin recovery at disease‐associated citrate levels.
