Uniting Seniors and Students in a Gift of Storytelling
The culminating event of a year-long collaboration between Laguna Blanca School and the hospice Sarah House will be performed in the Unitarian Society’s Parish Hall, May 27-28. Laguna Blanca serves those in early phases of life, whereas Sarah House serves those in life’s final phase, so how and why did these two seemingly polar opposite institutions unite?
Transcutaneous spinal cord stimulation neuromodulates pre- and postsynaptic inhibition in the control of spinal spasticity
Keywords human neuroplasticity non-invasive low-frequency depression postsynaptic inhibition presynaptic inhibition spasticity spinal cord circuits spinal cord injury spinal cord stimulation Introduction Epidural electrical stimulation (EES) has seemingly paradoxical effects on lower-limb motor function following spinal cord injury (SCI), with both enhancing dormant spinal excitability and thereby enabling voluntary control over otherwise paralyzed muscles,1,2 and suppressing the exaggerated...

Barren Tide Pools for Earth Day
With Earth Day approaching, the following question takes on even more importance.
Walk That E-Bike
Regarding dangerous biking on the State Street pedestrian areas, as an e-bike and e-trike rider myself, I am so sad that the e-bike speeders are ruining the lovely mixed-use situation for all bikers. I propose that a regulation be made that all e-bikes (except those used by handicapped persons) must be walked through the auto-free zones or risk getting citations or confiscations of their bikes.
A Dangerous Plan
Open Letter to Chancellor Yang, You have been a true wizard in the development of new buildings for our beloved campus, but the new controversial dorm plan is just one hugely dangerous mistake.
Substoichiometric ultrathin zirconia films cause strong metal-support interaction
Substoichiometric ultrathin zirconia films cause strong metal-support interaction The strong metal-support interaction (SMSI) leads to substantial changes of the properties of an oxide-supported catalyst after annealing under reducing conditions. The common explanation is the formation of heavily reduced, ultrathin oxide films covering metal particles. This is typically encountered for reducible oxides such as TiO2 or Fe3O4.
Water adsorption at zirconia: from the ZrO2(111)/Pt3Zr(0001) model system to powder samples
We present a comprehensive study of water adsorption and desorption on an ultrathin trilayer zirconia film using temperature programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS), as well as scanning tunneling microscopy (STM) at different temperatures. The saturation coverage is one H O per surface Zr atom, with about 12% dissociation.
Hypoxia triggers high-altitude headache with migraine features: A prospective trial
Background Given the high prevalence and clinical impact of high-altitude headache (HAH), a better understanding of risk factors and headache characteristics may give new insights into the understanding of hypoxia being a trigger for HAH or even migraine attacks. Methods In this prospective trial, we simulated high altitude (4500 m) by controlled normobaric hypoxia (F O = 12.6%) to investigate acute mountain sickness (AMS) and headache characteristics.
