Support assembly for cryogenically coolable low-noise choke waveguide

A compact cryogenically coolable choked waveguide for low-noise input coupling into a cryogenically cooled device, such as a maser or parametric amplifier, utilizes coaxial stainless steel support tubes surrounding the waveguide and connected in cascade to provide a folded low thermal conduction path. The edges of the tubes connected are welded

Low-noise microwave polarimeter

Two quarterwave-plate polarizers inserted between rotary waveguide joints transform received signals from arbitrary linear to circular polarizations and then from circular to fixed linear polarizations. Fixed linear polarizations are applied to amplifiers and filters in usual fashion

Human-wildlife interactions in conservation translocations: Developing guidelines

Workshop: Reintroductions and rewilding can be powerful tools in biodiversity recovery. We will introduce key Human-Wildlife Interaction issues that take place along the life cycle of a conservation translocation project, from planning to post-exit stages. Participants will be invited to discuss their experiences in HWI related to each of these stages, aiming to expand on findings from the Guidelines to Facilitate Human-Wildlife Interactions in Conservation Translocations (2022) to inform planning and promote wildlife conservation, collaboration amongst groups and coexistence

First exit times and residence times for discrete random walks on finite lattices

In this paper, we derive explicit formulas for the surface averaged first exit time of a discrete random walk on a finite lattice. We consider a wide class of random walks and lattices, including random walks in a non-trivial potential landscape. We also compute quantities of interest for modelling surface reactions and other dynamic processes, such as the residence time in a subvolume, the joint residence time of several particles and the number of hits on a reflecting surface.Comment: 19 pages, 2 figure
