Exercise limitations in amyloid cardiomyopathy assessed by cardiopulmonary exercise testing—A multicentre study

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1326-1335, April 2025.
Abstract Aims Amyloid cardiomyopathy is caused by the deposition of light chain (AL) or transthyretin amyloid (ATTR) fibrils, that leads to a restrictive cardiomyopathy, often resulting in heart failure (HF) with preserved or reduced ejection fraction.

QUARK-CLUSTER STARS: THE STRUCTURE

open access: yesInternational Journal of Modern Physics: Conference Series, 2013
The nature of pulsar-like compact stars is still in controversy although the first pulsar was found more than 40 years ago. Generally speaking, conventional neutron stars and non-mainstream quark stars are two types of models to describe the inner structure of pulsars, with the former composed mainly of hadrons and the latter of a peculiar kind of ...

Signals of the QCD Phase Transition in the Heavens [PDF]

open access: yes, 2007
The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.

Without Scratching the Surface: Depth Profiling Compositional Muon Analysis of Ancient Faience From Egypt and Sudan

open access: yesArchaeometry, EarlyView.
ABSTRACT The specific depth‐profiling capabilities of the muonic x‐ray emission spectroscopy (μ‐XES) technique have proved to be effective for examination of the elemental distribution within ancient coins. This ‘layered’ analysis can also be applied to the examination of ancient faience, the production of which can result in distinct layers (glaze ...

Strange Quark Stars — A Review [PDF]

open access: yesSymposium - International Astronomical Union, 2003
A pedagogical overview of strange quark matter and strange stars is presented. After a historical notation of the research and an introduction to quark matter, a major part is devoted to the physics and astrophysics of strange stars, with attention being paid to the possible ways by which neutron stars and strange stars can be distinguished in ...

Modellierung ultrarelativistischer Schwerionenkollisionen mit der Quark-Molekulardynamik qMD [PDF]

open access: yes, 2006
This thesis presents a model for the dynamical description of deconfined quark matter created in ultra-relativistic heavy ion collisions, treating quarks and antiquarks as classical point particles subject to a colour-dependent, Cornell-type potential ...

STAR highlights on heavy ion physics

open access: yesEPJ Web of Conferences, 2015
RHIC-STAR is a mid-rapidity collider experiment for studying high energy nuclear collisions. The main physics goals of STAR experiment are 1) studying the properties of the strongly coupled Quark Gluon Plasma 2) explore the QCD phase diagram structure ...

Radioactivity of quark nuggets

open access: yesJournal of High Energy Physics
Quark nuggets Q Z A $$ {}_{\textrm{Z}}{}^{\textrm{A}}\textrm{Q} $$ , as Fermionic non-topological solitons, could have their mass per baryon smaller than ordinary nuclei and behave as exotic nuclei with different relations of atomic number and atomic ...

Nature's Complexity Alive: Farewell to Several Unificatory Cosmological Arguments for Monism

open access: yesNoûs, EarlyView.
ABSTRACT Throughout history, numerous thinkers have claimed that monism—in the form of priority monism, existence monism, monotheistic monism, or versions that posit an extra‐cosmic ultimate being—theoretically surpasses pluralism, above all by positing a unified universe.
