Wafer‐Scale Dendritic Nanoporous Platinum Films for Neural Electrodes
Advanced Science, EarlyView.Wafer‐scale dendritic nanoporous platinum films with intrinsic nanoscale porosity are synthesized by suraface‐confined wet chemistry and transferred onto flexible substrates to create tissue‐conformal neural electrodes. The ultrathin films combine mechanical flexibility with electrochemical stability, enabling low‐impedance, high‐capacitance interfaces

A mathematical model of Cheyne-Stokes or periodic breathing
Mathematical BiosciencesCheyne-Stokes Breathing is a periodic cycle of apnea followed by hyperventilation. A theory of this phenomenon is developed based on a minimal set of physiological assumptions. The rate of loss of CO2 from venous blood is proportional to the CO2 concentration in the lungs times the respiration rate; the respiration rate is a linear function of arterial

Integrated breathing and relaxation training (the Papworth method) for adults with asthma in primary care: a randomised controlled trial [PDF]
, 2007 Background: An integrated breathing and relaxation technique known as the Papworth method has been implemented by physiotherapists since the 1960s for patients with asthma and dysfunctional breathing, but no controlled trials have been reported.
