A massive foreground cluster lens changes the shapes (shear effect) and number density (magnification effect) of the faint background galaxy population. In this paper we investigate how the shear, magnification and combined information can be used to constrain cluster mass profiles in the weak lensing regime. We develop maximum likelihood techniques to make quantitative predictions for each of ...

OBJECTIVES This study was conducted 1/ to find out the effects of anatomical sites and implant types on the magnification and 2/ to evaluate the inter-observer variability on the evaluation using the digital panoramas taken at daily practices. STUDY DESIGN Panoramic radiographs from 156 patients treated with implants were evaluated by three observers. The length was measured on the lateral as...

Technical Appendix Figure. Histopathologic changes associated with a 1918 type II pneumococcal pneumonia case and DNA sequence of a portion of the hemoglobin beta gene. A) Hematoxylin and eosin (H&E)–stained lung showing severe acute bacterial pneumonia with tissue necrosis (original magnification ×40). B) Brown and Hopps tissue Gram stained– lung showing abundant gram-positive cocci consistent...

Background: Early detection of occlusal caries in children is challenging for the dentists, because of the morphology of pit and fissures. Aim: The aim of the present study was to investigate the use of low-powered magnification (×2.5) and its association with LED headlight illumination for occlusal caries detection in primary and permanent molars using International Caries Detection and Assess...

OBJECTIVE To analyze whether less cumbersome loupes are as equally efficacious as the microscope for magnification for free tissue transfers in head and neck reconstruction. DESIGN A 7-year retrospective review of 151 consecutive microvascular free tissue transfers compares the operating microscope with loupe magnification. SETTING A tertiary care medical center. PATIENTS A total of 151 c...
