Exact subelliptic estimates forn−1 forms
Mathematische Zeitschrift, 1992 This paper deals with the problem of precise subelliptic estimate of the \(\overline\partial\)-Neumann problem for \(n-1\) forms. We prove that in a domain \(\Omega\subseteq\mathbb{C}^ n\) which is not necessarily pseudoconvex, if near \(z_ 0\in b\Omega\) there exists a holomorphic tangential vector field \(L\) whose Levi-form is non-negative and is ...

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.

The costs of adjusting labor: Evidence from temporally disaggregated data [PDF]
, 2011 I estimate the costs for establishments of hires and separations using a dynamic labor demand framework and matched employer-employee data from Germany, which records the exact dates of start and end of an employment spell.

Exact Nonlinear State Estimation
Journal of the Atmospheric SciencesAbstract The majority of data assimilation (DA) methods in the geosciences are based on Gaussian assumptions. While such approximations facilitate efficient algorithms, they cause analysis biases and subsequent forecast degradations. Nonparametric, particle-based DA algorithms have superior accuracy, but their application to high-dimensional models ...

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)

Exact estimates for monotone interpolation
Journal of Approximation Theory, 1980 AbstractLet 0 = xo < x1 < … < xn = 1, 0 = yo < y1 < … < yn \̌ 1 and let A, B, C be defined by (3); suppose further that C ⩾ con−1. We prove that for some constant c = c(co), depending only on co, there exists an algebraic polynomial P of degree ⩽ cn In (e + AB) for which P(xi) = yi, i = 1,…, n, and P′(x) ⩾ 0, 0 ⩽ x ⩽ 1.

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.

Cluster Statistics of BTW automata
, 2011 The cluster statistics of BTW automata in the SOC states are obtained by extensive computer simulation. Various moments of the clusters are calculated and few results are compared with earlier available numerical estimates and exact results.
