Controlling the Center of Mass Motion of Levitated Particles Using Structured Wavefronts

Laser &Photonics Reviews, EarlyView.
Optically levitated particles have great potential for quantum‐enhanced sensing. Precise control of the trapping beam is crucial to improve the stability and confinement of these systems. Here, we study how structured wavefronts can be used to control the center‐of‐mass motion of levitated particles, enhancing trap stiffness and enabling stable ...

Rotational Anisotropy Raman Spectrometer for High‐Sensitivity Crystallographic Symmetry Analysis

Laser &Photonics Reviews, EarlyView.
We introduce rotational‐anisotropy Raman spectroscopy, an enhanced scheme that overcomes the limitations of traditional polarization‐resolved Raman techniques. This method reveals previously inaccessible phonon symmetries and resolves directional anisotropy of phonon‐polaritons in benchmark crystals, establishing a powerful new tool for characterizing ...

CLASPs prevent irreversible multipolarity by ensuring spindle-pole resistance to traction forces during chromosome alignment

, 2012
Loss of spindle-pole integrity during mitosis leads to multipolarity independent of centrosome amplification. Multipolar-spindle conformation favours incorrect kinetochore-microtubule attachments, compromising faithful chromosome segregation and daughter-

Multispectral Mid‐Infrared Imaging With Incoherent Light via Adiabatic Upconversion

Laser &Photonics Reviews, EarlyView.
We demonstrate room‐temperature broadband MIR imaging based on adiabatic frequency upconversion, driven by a Q‐switched pump laser and incoherent illumination. The small‐foot‐print system upconverts the spectral range to the visible domain, without scanning, thermal control and with spatial resolution below 20μm$20\mathrm{\mu}\mathrm{m}$.

Spin‐Polarized Magnetic Metal Electrodes for Magnetic Tunnel Junctions

MetalMat, EarlyView.
This perspective surveys spin‐polarized magnetic metal electrodes for magnetic tunnel junctions, systematically covering conventional ferromagnets, collinear/noncollinear antiferromagnets, and emergent altermagnets. It compares tunneling polarization origins across these classes and emphasizes that effective electrode polarization is a momentum ...

Reflections on Comparative Teaching in Public Administration

Public Administration and Development, EarlyView.
ABSTRACT This article integrates our scholarly experience of teaching comparative public administration. In doing so, we offer a unique perspective as the co‐authors carry several diverse attributes, among them their countries of origin, current country in which they are teaching, and their academic experience.

Comprehensive analysis of microtubule‐inhibiting herbicides reveals shared subcellular phenotypes and distinct resistance profiles

Pest Management Science, EarlyView.
Using cellular phenotyping and resistance profiling, we show that herbicides across the Herbicide Resistance Action Committee (HRAC) Groups 3 and 23 induce indistinguishable, dose‐dependent microtubule defects. Resistance patterns, rather than cellular phenotypes, reveal distinct sites of action and support reclassifying Group 3 as α‐tubulin binders ...

Secure Enough? Sufficiency and Security in the New Geological and Geopolitical Reality

Sustainable Development, EarlyView.
ABSTRACT This article advances sufficiency theorizing by examining its relationship with security in the contemporary geopolitical context. It engages three contextually situated discourses: sustainable development, ecological civilization, and degrowth, to explore how concerns over ecological limits intersect with emerging geopolitical and security ...

Multi‐Scale Engineering of Photonic Meta‐Structures With Emergent Optical Resonances via Colloidal Crystal Engineering With DNA and Microwell Templates

Small, EarlyView.
This work presents a bottom‐up strategy for forming meta‐structures built from DNA‐assembled nanoparticle superlattices, establishing a versatile platform for multiscale photonic materials design. Confinement stabilizes non‐equilibrium crystal habits and enables geometry and mode control independent of lattice symmetry.
