DC transport in a dissipative superconducting quantum point contact
Physical Review Research, 2023 We study the current-voltage characteristics of a superconducting junction with particle losses at the contacts. We adopt the Keldysh formalism to compute the steady-state current for varying transmission of the contact.

On the spreading of impacting drops [PDF]
, 2016 The energy budget and dissipation mechanisms during droplet impact on solid surfaces are studied numerically and theoretically. We find that for high impact velocities and negligible surface friction at the solid surface (i.e.

Quantitative assessment of dissipative losses of 18 metals [PDF]
Resources, Conservation and Recycling, 2020 Abstract Dissipative losses of metals are unrecoverable material flows representing the real consumption of metals. They occur during any process in the global metal cycle from primary production to waste management and have different receiving mediums.

Heat dissipation during hovering and forward flight in hummingbirds [PDF]
Royal Society Open Science, 2015 Flying animals generate large amounts of heat, which must be dissipated to avoid overheating. In birds, heat dissipation is complicated by feathers, which cover most body surfaces and retard heat loss.

Studies of dissipative standing shock waves around black holes [PDF]
, 2009 We investigate the dynamical structure of advective accretion flow around stationary as well as rotating black holes. For a suitable choice of input parameters, such as, accretion rate ($\dot {\cal M}$) and angular momentum ($\lambda$), global accretion ...

High-Q Nanomechanics via Destructive Interference of Elastic Waves
, 2010 Mechanical dissipation poses an ubiquitous challenge to the performance of nanomechanical devices. Here we analyze the support-induced dissipation of high-stress nanomechanical resonators. We develop a model for this loss mechanism and test it on silicon
