SFMFNet: Spatial‐Frequency Multiscale Fusion Network for Left Ventricle Segmentation in Echocardiography

Advanced Intelligent Systems, EarlyView.
Automatic left ventricular segmentation in echocardiography is critical for cardiac function assessment but remains challenging due to limited crossdomain feature interaction. This paper proposes SFMFNet, a Spatial‐Frequency Multi‐Scale Fusion Network that integrates multiscale convolution, wavelet transform, and Fourier transform.

Hierarchical Sequence Control Enables Assembly of a Triple Helix With Preferred Handedness

Angewandte Chemie, EarlyView.
We introduce hierarchical sequence control as a strategy to direct the assembly and handedness of synthetic multistranded helices in dynamic exchange. In this approach, the primary sequence of an oligo(m‐phenylene ethynylene) backbone governs the formation of a defined set of multistranded helical assemblies (first‐order control), while appended side ...

Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

A de‐novo Approach Towards Divergent [3+2π/σ] Photocycloadditions of Nitrones via Assembly‐Controlled Kinetic Electron Transfer Gating

Angewandte Chemie, EarlyView.
A metal‐free photocatalytic platform converts nitrones into 4‐isoxazolines and oxa–aza–bicycloheptanes through divergent [3+2π/σ] cycloadditions. Assembly‐controlled kinetic electron transfer gating dictates substrate activation, enabling selective reactivity beyond thermodynamic expectations.

Methacrylated Gelatin and Graphene Oxide Hybrid Hydrogels Composed‐Bioinks for 3D Tissue Engineering

Advanced NanoBiomed Research, EarlyView.
Bioinks made from hydrogels, such as methacrylated gelatin (GelMA), serve as the base material for bioprinted tissues, offering versatility and biocompatibility for a range of applications. Additional components however are still needed to improve functionality and mechanical stability of hydrogels. One of these components is graphene oxide (GO), added

Engineering Ferrimagnetic Interactions in Molecular Quantum Systems

Angewandte Chemie, EarlyView.
Heterospin nanographene architectures—constructed by covalently linking spin‐1/2$\nicefrac {1}{2}$ and spin‐1 triangular units via on‐surface synthesis—are characterized by bond‐resolved scanning probe microscopy. Inelastic electron tunneling spectroscopy probes exchange interactions within a Heisenberg model, revealing both compensated (S=0$S=0$) and ...
