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.

Maps on essentially infinite idempotent operators
Journal of Mathematical Analysis and Applications, 2012 Let \(X\) be an infinite-dimensional real or complex Banach space, and \({\mathcal I}(X)\) be the set of all idempotents in the algebra \(B(X)\) of all bounded linear operators on \(X\). In [Stud. Math. 169, No. 1, 21--44 (2005; Zbl 1088.47030)], \textit{P.

Beyond Dualisms in Methodology: An Integrative Design Research Medium "MAPS" and some Reflections [PDF]
, 2009 Design research is an academic issue and increasingly an essential success factor for industrial, organizational and social innovation. The fierce rejection of 1st generation design methods in the early 1970s resulted in the postmodernist attitude of "no

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)

Bayesian analysis of retinotopic maps
eLife, 2018 Human visual cortex is organized into multiple retinotopic maps. Characterizing the arrangement of these maps on the cortical surface is essential to many visual neuroscience studies. Typically, maps are obtained by voxel-wise analysis of fMRI data. This

Compactification for essentially finite-type maps
Advances in Mathematics, 2009 We show that any separated essentially finite-type map $f$ of noetherian schemes globally factors as $f = hi$ where $i$ is an injective localization map and $h$ a separated finite-type map. In particular, via Nagata's compactification theorem, $h$ can be chosen to be proper. We apply these results to Grothendieck duality.

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Gps Essential For Mapping Species Distribution
, 2018 Conservation of our environment is the important phenomenon which includes integration of government, scientist and local community to understand the fauna or flora present in a particular region. This is where the role citizen science comes to play. In addition to the community technological collaboration will results in scientific conclusion for any ...

Essential dimension lowering mappings having dense deficiency set [PDF]
Transactions of the American Mathematical Society, 1985 A map \(f: X\to Y\) is said to be one-to-one over the image of \(D\subset X\) provided the restriction of f yields a homeomorphism from \(f^{- 1}(f(D))\to f(D)\). It is perhaps startling to find maps that are one-to- one over the image of a dense subset that represent any element of \(\pi_ n(S^ n)\) for \(n\geq 3\), the only obvious one being the ...
