We show how calculable IR loop effects impact positivity bounds in effective field theories with causal and unitary UV completions. identify infrared singularities that appear dispersion relations at $|t|\ensuremath{\lesssim}{m}^{2}$. In the massless limit, they weaken two-sided based on crossing symmetry, such as lower bound amplitude for Galileon scattering. For amplitudes are analytic $s$ ev...

OBJECTIVES Although elevated cardiac troponin T is caused by myocardial damage in the vast majority of the cases (primary cardiac causes), noncardiac disease with secondary damage to the myocardium (secondary cardiac causes) is being increasingly recognised. The present study aimed to retrospectively evaluate the frequency of primary cardiac and secondary cardiac causes of troponin-T positivity...

In this article, using a twisted version of Hörmander’s L 2 -estimate, we give new characterizations notions partial positivity, which are uniform q-positivity and RC-positivity. We also discuss the definition for singular Hermitian metrics.

BACKGROUND It is well known that anti-GAD (glutamic acid decarboxylase) serves as a marker for development of autoimmune diabetes in adults. On the other hand, the clinical implications of anti-GAD positivity in persistently non-diabetic (PND) adults are poorly elucidated. Our aim was to establish the frequency of anti-GAD in PNDs in an all-population-based cohort from the Nord-Trøndelag health...
