This paper proposes a performance analysis of a medium-range airliner powered by liquid hydrogen (LH2) propulsion.The focus is on operating performance in terms of achievable payload and range.A non-conventional box-wing architecture was selected to maximize operating performance.An optimization-based multidisciplinary design framework was develope
A significant challenge in Prehistory is to understand the mechanisms involved in the behavioural evolution of human groups.The degree of technological and cultural development of prehistoric groups is assessed mainly through stone tools.However, other elements can provide valuable Denim information as well.This paper presents two bone retouchers d
A variety of circumstantial evidence from humans has implicated the B cell antigen receptor (BCR) in the genesis of B cell lymphomas.We generated mouse models designed to test this possibility directly, and we found that both the constitutive and antigen-stimulated state of a clonal BCR affected the rate and outcome of lymphomagenesis initiated by
The article reviews the history development of artificial neural networks (ANNs), then compares the differences between ANNs and brain networks in Sweater Dresses their constituent unit, network architecture, and dynamic principle.The authors offer five points of suggestion for ANNs development and ten questions to be investigated further for the i
