Weighing neutrinos with large-scale structure
While it is established that the effect of neutrinos on the evolution of cosmic structure is small, the upper limits derived from large-scale structure could help significantly to constrain the absolute scale of the neutrino masses. Current results from cosmology set an upper limit on the sum of the neutrino masses of ∼ 1 eV, somewhat depending on the data sets used in the analyses and assumed ...
متن کاملWeighing wet diapers: a new approach to measuring infant output.
Accurate measurement of fluid losses is important in infant patients, especially in burn cases. Indwelling catheters, urine collection bags and other commonly used methods of continuous urine collection and measurement have several disadvantages including trauma, danger of infection, skin irritation, need for restraints, and use of expensive devices. The present study was designed to ascertain ...
متن کامل“Bees?” A Large Scale, Cooperative Simulation Weighing Altruism and Selfishness
In nature, communities that revolve around altruistic cooperation exist: for example, a bee colony, where individual bees retrieve nectar for the communal hive rather than scouting selfishly for their own survival. Although cooperation can certainly be implemented into an artificial life simulation, from an evolutionary standpoint a more interesting question is raised: can the interactions of a...
متن کاملWeighing nanoparticles in solution at the attogram scale.
Physical characterization of nanoparticles is required for a wide range of applications. Nanomechanical resonators can quantify the mass of individual particles with detection limits down to a single atom in vacuum. However, applications are limited because performance is severely degraded in solution. Suspended micro- and nanochannel resonators have opened up the possibility of achieving vacuu...
متن کاملIn the balance: weighing babies and the birth of the infant welfare clinic.
The nineteenth century saw the incorporation of technology, such as the stethoscope, microscope, and thermometer, into clinical medicine. An instrument that has received less attention in the history of the role of technology in medicine is the weighing balance, or scale. Although not new to nineteenth-century medicine, it played an important part in the rise of the numerical method and its app...
