There is a fundamental relationship between projective geometry and the perspective imaging geometry of a pinhole camera.Projective scales have been used to measure within images from the beginnings of photogrammetry, mostly the cross-ratio on a straight line.However, there are also projective frames in the plane with interesting connections to aff
Multiple electron impacting (multipacting) can take place in rf fields when the rf components are composed of materials with a secondary electron yield greater than one.In rf gun cavities, multipacting may change the properties of the vacuum components or even damage them.First systematic measurements of the multipacting occurring in a photocathode
With declaring the highly transmissible COVID-19 as a pandemic, an unprecedented strain on healthcare infrastructures worldwide occurred.An enormous shortage in the personal protective equipment (PPE) and the spare parts (SP) for the mechanical ventilators ensued as a consequence of the failure of the centralized global supply chains.Additive manuf
This study explores the memory of the Soviet period in Moldova, focusing on how social trauma and contemporary politics influence perceptions of the past.Utilizing oral history methods, over 60 interviews were conducted in Moldova during the latter half of 2023, encompassing a diverse range of respondents aged from their 20s to 90s.The research spa
Peptide based vaccines offer several advantages over conventional whole organism or protein approaches by offering improved purity and specificity in inducing immune response.However, peptides alone are animationbengal.com generally non-immunogenic.Concerns remain about the toxicity of adjuvants which are critical for immunogenicity of synthetic pe
