Report presenting the results of a wind-tunnel investigation to determine the effects of a variation in wing taper ratio on the longitudinal characteristics of a wing-body combination at a variety of Mach numbers. The wings had an aspect ratio of 3, an unswept midchord line, and an NACA 64A003 profile. Results regarding the lift and pitching-moment characteristics and drag characteristics are provided

Report presenting an experimental investigation conducted to determine the lateral-directional aerodynamic characteristics at transonic speeds of missile configurations with three blunted cone-cylinder bodies. Modifications of the basic model were tested to determine the effects of relative lengths of the bodies and the effects of seals between the cylindrical parts of the bodies. Cross-wind force, drag, yawing moment, and rolling moment were measured through a range of angles of sideslip, angles of attack, and Mach numbers

"Results are presented for a wind-tunnel investigation of an airplane model with a 3.4-percent-thick unswept wing of aspect ratio 2.45 at Mach numbers from 0.8 to 1.4 at a Reynolds number of 1.5 million. Longitudinal characteristics are presented for the basic model and for configuration variations involving two types of wing camber, an area-rule fuselage modification, various external-store arrangements, several conventional missile installations and one designed according to the moment-of-area concept, and two fuselage dive-flap arrangements. Lateral-directional characteristics of the basic model with and without the empennage are also included" (p. 1)

The immuno-oncological challenge of COVID-19
International audienceCoronavirus disease 2019 (COVID-19) and its causative virus, SARS-CoV-2, pose considerable challenges for the management of oncology patients. COVID-19 presents as a particularly severe respiratory and systemic infection in aging and immunosuppressed individuals, including patients with cancer. Moreover, severe COVID-19 is linked to an inflammatory burst and lymphopenia, which may aggravate cancer prognosis. Here we discuss why those with cancer are at higher risk of severe COVID-19, describe immune responses that confer protective or adverse reactions to this disease and indicate which antineoplastic therapies may either increase COVID-19 vulnerability or have a dual therapeutic effect on cancer and COVID-19. Zitvogel and colleagues discuss the interplay between cancer and COVID-19 with respect to patient risk and prognosis, immune responses and potential therapies
