We show that the Veneziano amplitude of string theory is the unique solution to an analytically solvable bootstrap problem. Uniqueness follows from two assumptions: faster than power-law falloff in high-energy scattering and the existence of some infinite sequence in momentum transfer at which higher-spin exchanges cancel. The string amplitude-including the mass spectrum-is an output of this bootstrap.

The purpose of this retrospective study is to perform an observational analysis of GES meals that are used within a national radiology practice to assess for compliance. It is hypothesized that despite having well-validated standardized meal protocols, there remains great variability in its use and interpretation.

- - The spatial distribution of component species in electroactive film devices is crucial for understanding their performance, influencing both transport rates and mechanical properties.
- - Specular neutron reflectivity (NR) is a technique that can profile individual species at "buried" interfaces, although it has traditionally had poor time resolution.
- - This study demonstrates improved NR measurements that allow for spatial and temporal resolution during processes like polypyrrole electrodeposition and copper deposition/dissolution, revealing insights into film homogeneity and complex solvent interactions.
The concept of emotional labor refers to the regulation and management of emotions within the workplace. This labor may involve a dissonance between the emotions that are internally felt and the emotions that can be externally expressed. The concept of emotional labor can be applied to the emotional management that occurs during research often when directly interacting with research participants.
View Article and Find Full Text PDFRationale And Objectives: To investigate and discern if preferences and expectations regarding the stylistics of the radiology report varied across roles, specialties, and practice location amongst referring providers.
Materials And Methods: A total of 579 referring clinicians were invited to complete our survey electronically and were asked to identify themselves as either physicians or advanced practice providers (APPs), specify their specialty, and primary practice environment. They were asked to rank the three reports on appearance, formatting, level of detail, and overall preference, with additional queries about their preferences regarding literature citation inclusions and placement of dose reduction statements.
