Three-dimensional laser velocimeter simultaneity detector [PDF]

, 1990
A three-dimensional laser Doppler velocimeter has laser optics for a first channel positioned to create a probe volume in space, and laser optics and for second and third channels, respectively, positioned to create entirely overlapping probe volumes in ...

The coupled-cluster approach to quantum many-body problem in a three-Hilbert-space reinterpretation [PDF]

, 2013
The quantum many-body bound-state problem in its computationally successful coupled cluster method (CCM) representation is reconsidered. In conventional practice one factorizes the ground-state wave functions $|\Psi\rangle= e^S |\Phi\rangle$ which live ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Emergent Knowledge in the Third Space of Art-Science

Leonardo: Journal of the International Society for the Arts, Sciences and Technology, 2020
The locus of encounter between art, science and the public can be conceptualized as third space—a generative site of shared experience. This article reports on a group-based psychosocial method led by imagery and affect—the visual matrix—that enables ...

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

On third space and critical paralysis

Journal of Learning Development in Higher Education
The concept of ‘third space’ in HE identifies an emerging area of work and consequent development of roles and practices which exist ‘in-between' academic and professional departments of universities (Whitchurch, 2013).
