Matrix power means and the Karcher mean
Journal of Functional Analysis, 2012 The Karcher mean of \(n\) positive definite matrices \(A_{1},\dots,A_{n}\) is defined as the unique minimizer (provided it exists) of the sum of squares of the Riemannian trace metric distances to each of the \(A_{i}\), i.e., \[ \Lambda (A_{1},\dots,A_{n})=\arg \min_{X\in {\mathbb P}}\sum\limits_{i=1}^{n}\delta ^{2}(X,A_{i})~, \] where \ \({\mathbb P}\)

The power mean and the logarithmic mean [PDF]
International Journal of Mathematics and Mathematical Sciences, 1980 In a very interesting and recent note, Tung‐Po Lin [1] obtained the least value q and the greatest value p such that urn:x-wiley:01611712:media:ijmm718951:ijmm718951-math-0001 is valid for all distinct positive numbers x and y where urn:x-wiley:01611712:media:ijmm718951:ijmm718951-math-0002 The object of this paper is to give a simpler proof than

Dietary Protein Intake and Peritoneal Protein Losses in Peritoneal Dialysis Patients
Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Peritoneal dialysis (PD) patients lose protein in their waste dialysate, potentially increasing their risk for malnutrition. We wished to determine whether there was any association between losses and dietary protein intake (DPI). Methods DPI was assessed from 24‐h dietary recall using Nutrics software.

DISTRIBUTED GENERATION IS A MEANS OF INCREASING POWER SYSTEM SURVIVABILITY
Известия высших учебных заведений: Проблемы энергетики, 2017 Today we observe an increase in the amount of cogeneration plants with capacity up to 25 MW. We offer the approach that allows more efficient use of distributed generation.

Interval-type theorems concerning means [PDF]
, 2017 Each family $\mathcal{M}$ of means has a natural, partial order (point-wise order), that is $M \le N$ iff $M(x) \le N(x)$ for all admissible $x$. In this setting we can introduce the notion of interval-type set (a subset $\mathcal{I} \subset \mathcal{M}

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.
