Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Kubo formulas for thermodynamic transport coefficients
Journal of High Energy Physics, 2018 Uncharged relativistic fluids in 3+1 dimensions have three independent thermodynamic transport coefficients at second order in the derivative expansion. Fluids with a single global U(1) current have nine, out of which seven are parity preserving.

Convergence of chiral effective field theory
, 2002 We formulate the expansion for the mass of the nucleon as a function of pion mass within chiral perturbation theory using a number of different ultra-violet regularisation schemes; including dimensional regularisation and various finite-ranged regulators.

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.

Soft scalars in effective field theory
Journal of High Energy PhysicsWe derive a soft theorem for a massless scalar in an effective field theory with generic field content using the geometry of field space. This result extends the geometric soft theorem for scalar effective field theories by allowing the massless scalar ...

Complex-mass scheme and effective field theory
EPJ Web of Conferences, 2014 The complex-mass scheme applied to hadronic effective field theory is briefly introduced. Some conceptual issues and the application to the calculation of the one-loop corrections to the ρ-meson magnetic moment are discussed.

The geometric Standard Model Effective Field Theory
Journal of High Energy Physics, 2020 We develop the geometric formulation of the Standard Model Effective Field Theory (SMEFT). Using this approach we derive all-orders results in the 2 H † H / Λ $$ \sqrt{2\left\langle {H}^{\dagger }H\right\rangle }/\Lambda $$ expansion relevant for studies

Effective Field Theory for Long Strings
, 2013 In previous work we used magnetic SU(N) gauge theory with adjoint representation Higgs scalars to describe the long distance quark-antiquark interaction in pure Yang-Mills theory, and later to obtain an effective string theory. The empirically determined

Effective Field Theories [PDF]
, 2013 This chapter reviews effective field theory (EFT) techniques, focusing on the intertheoretic relations between low-energy effective theories and their high-energy counterparts. It discusses how EFT can be interpreted and describes the steps in the construction of an EFT in the top-down and bottom-up approaches.
