The complete LQG propagator: I. Difficulties with the Barrett-Crane vertex [PDF]

Phys.Rev.D76:104012,2007, 2007
Some components of the graviton two-point function have been recently computed in the context of loop quantum gravity, using the spinfoam Barrett-Crane vertex. We complete the calculation of the remaining components. We find that, under our assumptions, the Barrett-Crane vertex does not yield the correct long distance limit.

Cost–benefit analysis and ‘next best’ methods to evaluate the efficiency of social policies: As in pitching horseshoes, closeness matters

Annals of Public and Cooperative Economics, EarlyView.
Abstract Many policymakers are unwilling, or think that it is infeasible, to perform comprehensive cost–benefit analysis (CBA) of programmes in social policy arenas. What principles actually underlie CBA? An understanding is necessary to assess whether other evaluation methods are close enough to CBA to provide useful information on social efficiency ...

Meta‐Analysis: Inverse Association Between Helicobacter pylori Infection and Eosinophilic Oesophagitis

Alimentary Pharmacology &Therapeutics, Volume 61, Issue 7, Page 1096-1109, April 2025.
In a large systematic review and meta‐analysis, exposure to Helicobacter pylori was significantly associated with decreased odds (46%) of eosinophilic oesophagitis and oesophageal eosinophilia. ABSTRACT Background Exposure to Helicobacter pylori (H. pylori) has been associated with a decreased risk of eosinophilic oesophagitis (EoE).

Pressure -- area loop based phenotypic classification and mechanics of esophagogastric junction physiology [PDF]

arXiv, 2022
The esophagogastric junction (EGJ) is located at the distal end of the esophagus and acts as a valve allowing swallowed materials to enter the stomach and preventing acid reflux. Irregular weakening or stiffening of the EGJ muscles result in changes to its opening and closing patterns which can progress into esophageal disorders.
