Dirac quasinormal modes of two-dimensional charged Dilatonic Black Holes
We study charged fermionic perturbations in the background of two-dimensional
charged Dilatonic black holes, and we present the exact Dirac quasinormal
modes. Also, we study the stability of these black holes under charged
fermionic perturbations.Comment: version accepted for publication in EPJC. arXiv admin note:

Discharge Prospectus
Background and Purpose:
The goals of the project are to improve the efficiency of the discharge process, to increase bed availability, to decrease readmission rates, and to increase patient satisfaction through implementation of multidisciplinary huddles.
Methods:
The intervention of the huddle took place on a medical-surgical unit at UC Davis Medical Center in the local Sacramento area serving various Medical Services.
This was a prospective pre- and post-quality intervention by utilizing HCAPHS survey, electronic medical record, RN surveys, and discharge data collection.
Results:
Discharges were increased from 15% to 23%. Currently, data is up-to-date for nine months but the project rolls until January 2017. Patient satisfaction scores increased by 3%. Re-admission results were essentially unchanged in comparison to the national average.
Conclusions:
Multidisciplinary huddles should continue to be used to assist in optimizing the efficiency of discharges, assisting in transition of care for patients, to help increase communication across team members, and to help increase patient satisfaction
Changes in the carbon balance of tropical forest: evidence from long-term plots
The role of the world’s forests as a “sink” for atmospheric carbon dioxide is the subject of active debate. Long-term monitoring of plots in mature humid tropical forests concentrated in South America revealed that biomass gain by tree growth exceeded losses from tree death in 38 out of 50 neotropical sites. These forest plots have accumulated 0.71 + 0.34 tons of carbon per hectare per year in recent decades. The data suggest that neotropical forests may be a significant carbon sink, reducing the rate of increase in atmospheric CO2

Transitions Between Convective Patterns in Chemical Fronts
We present a theory for the transition from nonaxisymmetric to axisymmetric convection in iodate-arsenous acid reaction fronts propagating in a vertical slab. The transition takes place away from the onset of convection, where a convectionless flat front becomes unstable to a nonaxisymmetric convective front. The transition is studied by numerically solving a reaction-diffusion equation coupled with nonlinear hydrodynamics in a two-dimensional slab
Transformation elastodynamics and active exterior acoustic cloaking
This chapter consists of three parts. In the first part we recall the
elastodynamic equations under coordinate transformations. The idea is to use
coordinate transformations to manipulate waves propagating in an elastic
material. Then we study the effect of transformations on a mass-spring network
model. The transformed networks can be realized with "torque springs", which
are introduced here and are springs with a force proportional to the
displacement in a direction other than the direction of the spring terminals.
Possible homogenizations of the transformed networks are presented, with
potential applications to cloaking. In the second and third parts we present
cloaking methods that are based on cancelling an incident field using active
devices which are exterior to the cloaked region and that do not generate
significant fields far away from the devices. In the second part, the exterior
cloaking problem for the Laplace equation is reformulated as the problem of
polynomial approximation of analytic functions. An explicit solution is given
that allows to cloak larger objects at a fixed distance from the cloaking
device, compared to previous explicit solutions. In the third part we consider
the active exterior cloaking problem for the Helmholtz equation in 3D. Our
method uses the Green's formula and an addition theorem for spherical outgoing
waves to design devices that mimic the effect of the single and double layer
potentials in Green's formula.Comment: Submitted as a chapter for the volume "Acoustic metamaterials:
