Feasibility Test of the MedaCube
Poor adherence is a significant barrier to achieve better patient outcomes. Rates of non-adherence approach 40% resulting in 10% of all emergency department visits and 23% of admissions into skilled nursing facilities. Many factors contribute to medication non-adherence including psychological and memory disorders, aging and pill burden. The MedaCube is a medication management system intended to help solve unintentional medication non-adherence. The device is designed to dispense scheduled and as-needed oral medications. The MedaCube provides audio and visual prompts alerting subjects to administer their medications. Caregivers receive notification of missed doses, late doses and refill requests. The null hypothesis is that use of the MedaCube results in no difference in medication adherence when compared with six month prior adherence in individual subjects
Magnetothermodynamics: Measuring equations of state in a relaxed magnetohydrodynamic plasma
We report the first measurements of equations of state of a fully relaxed
magnetohydrodynamic (MHD) laboratory plasma. Parcels of magnetized plasma,
called Taylor states, are formed in a coaxial magnetized plasma gun, and are
allowed to relax and drift into a closed flux conserving volume. Density, ion
temperature, and magnetic field are measured as a function of time as the
Taylor states compress and heat. The theoretically predicted MHD and double
adiabatic equations of state are compared to experimental measurements. We find
that the MHD equation of state is inconsistent with our data.Comment: 4 pages, 4 figure

Magnetothermodynamics: Measurements Of The Thermodynamic Properties In A Relaxed Magnetohydrodynamic Plasma
We have explored the thermodynamics of compressed magnetized plasmas in laboratory experiments and we call these studies ‘magnetothermodynamics’. The experiments are carried out in the Swarthmore Spheromak eXperiment device. In this device, a magnetized plasma source is located at one end and at the other end, a closed conducting can is installed. We generate parcels of magnetized plasma and observe their compression against the end wall of the conducting cylinder. The plasma parameters such as plasma density, temperature and magnetic field are measured during compression using HeNe laser interferometry, ion Doppler spectroscopy and a linear dot{B} probe array, respectively. To identify the instances of ion heating during compression, a PV diagram is constructed using measured density, temperature and a proxy for the volume of the magnetized plasma. Different equations of state are analysed to evaluate the adiabatic nature of the compressed plasma. A three-dimensional resistive magnetohydrodynamic code (NIMROD) is employed to simulate the twisted Taylor states and shows stagnation against the end wall of the closed conducting can. The simulation results are consistent to what we observe in our experiments
Geological Evidence of Paleotsunamis at Torre degli Inglesi (northeast Sicily)
Two layers of fine sand of marine origin occur in a
sequence of organic rich colluvia in an archaeological
excavation at Torre degli Inglesi, on Capo Peloro, northeast
Sicily. Stratigraphic and micropaleontologic analyses
support the hypothesis that these layers are related to
deposition due to paleotsunami waves. Their ages are
constrained both with radiocarbon and archaeological
datings. The age of the oldest layer is coincident with the
17 A.D. earthquake that hit Reggio Calabria but for which
no tsunami was previously reported. The age of the
youngest layer can be only constrained in the range 3rd–
19th century and is tentatively associated to the 6 Feb. 1783
event
Discrimination of tsunami sources (Earthquake vs. Landslide) on the basis of historical data in Eastern Sicily and southern Calabria
The source mechanisms responsible for large historical tsunamis that
have struck eastern Sicily and southern Calabria are a topic of robust debate. We have
compiled a database of historical coeval descriptions of three large tsunamis: 11 January
1693, 6 February 1783, and 28 December 1908. By using accounts of run-up and
inundation and employing an approach proposed by Okal and Synolakis in 2004, we
can provide discriminants to define the nature of the near-field tsunami sources (fault
dislocation or landslide).
Historical reports for the 1908 event describe affected localities, maximum runups,
and inundation areas. However, for the 1693 and 1783 tsunamis, reports are
limited to inundation and occasional run-up estimates. We calculate run-up values
for these events using available relations between inundation and run-up. We
employed the model of Okal and Synolakis to the obtained profiles of tsunami
run-up along the inundated shorelines. The 1908 run-up data distribution confirms
that the tsunami is compatible with a seismic dislocation source, whereas the
1783 data supports contemporary observations and recent offshore investigations suggesting
that the tsunami was produced by an earthquake-triggered submarine landslide.
Analysis of the 1693 event data suggests that the tsunami was generated
during a tectonic event and thus a seismogenic source should be found offshore
