Efficient Circular Thresholding [PDF]
IEEE Transactions on Image Processing, 2014 Otsu's algorithm for thresholding images is widely used, and the computational complexity of determining the threshold from the histogram is O(N) where N is the number of histogram bins. When the algorithm is adapted to circular rather than linear histograms then two thresholds are required for binary thresholding.

The Circularity Assessment Protocol in Cities to Reduce Plastic Pollution
Community ScienceThe circular economy has been promoted as a solution to plastic pollution, but cities and communities bear the brunt of plastic pollution. The Circularity Assessment Protocol (CAP) is a systems method of collaborative and open data collection for ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Adult‐onset Still's disease (AOSD) complicated by macrophage activation syndrome (MAS) carries substantial mortality. The role of therapeutic plasma exchange (TPE) remains uncertain. Methods We retrospectively analyzed patients with AOSD‐MAS treated with TPE at a single‐center.

Advances in Statistics, 1997 This paper studies the conjecture that the empirical spectral distribution of an \(n\times n\) matrix of i.i.d. entries \(\xi_{kj} =(1/ \sqrt n) x_{kj}\) and \(\{x_{kj},\;k,j=1,2, \dots\}\) forming an infinite double array of i.i.d. complex random variables converges to the uniform distribution over the unit disc on the complex plane, which is called ...

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
