Dynamical renormalization and universality in classical multifield cosmological models
Nuclear Physics B, 2022 We study the scaling behavior of classical multifield cosmological models with complete scalar manifold (M,G) and positive smooth scalar potential Φ, introducing a dynamical renormalization group action which relates their UV and IR limits.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Scalar cosmology with multi-exponential potentials [PDF]
Classical and Quantum Gravity, 2005 We investigate cosmologies with an arbitrary number of scalars and the most general multi-exponential potential. By formulating the equations of motion in terms of autonomous systems we complete the classification of power-law and de Sitter solutions as critical points, e.g. attractor and repeller solutions, in terms of the scalar couplings.

Quantum corrections to gravitational potential of scalarized neutron star binary
European Physical Journal C: Particles and Fields, 2019 We investigate the long-distance, low-energy, leading quantum corrections to gravitational potential for scalarized neutron star (NS) binary systems, by treating general relativity as an effective field theory.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.

Effective potential in scalar field theory [PDF]
Physical Review D, 1987 We study the \ensuremath{\lambda}${\ensuremath{\varphi}}^{4}$ theory in 4 space-time dimensions in a Monte Carlo simulation on a ${10}^{4}$ lattice, through an especially simple and accurate way to calculate the effective potential. All renormalized parameters are obtained via the effective potential and the propagator.

Neutron stars in scalar–tensor gravity with quartic order scalar potential
Annals of Physics, 2022 In this work we investigate the effects of a non-minimally coupled quartic order scalar model on static neutron stars, with the non-minimal coupling in the Jordan frame being of the form $f(ϕ) = 1 + ξϕ^2$. Particularly we derive the Einstein frame Tolman-Oppenheimer-Volkoff equations, and by numerically integrating them for both the interior and the ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Accidental symmetries in the scalar potential of the Standard Model extended with two Higgs triplets
Journal of High Energy Physics, 2022 The extension of the Standard Model (SM) with two Higgs triplets offers an appealing way to account for both tiny Majorana neutrino masses via the type-II seesaw mechanism and the cosmological matter-antimatter asymmetry via the triplet leptogenesis.

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...
