Guilty But Mentally Ill: The Ethical Dilemma Of Mental Illness As A Tool Of The Prosecution
While other jurisdictions use guilty but mentally ill as a compromise verdict to fill the gap between guilty by reason of insanity and a guilty verdict after an unsuccessful insanity defense, Alaska has transformed the status into a prosecutorial tool to keep mentally ill defendants incarcerated for longer than their mentally sane counterparts through denial of “good time” credit. Although Blakely was used—correctly—to prevent the denial of the mentally ill their Sixth Amendment right to a trial by jury and proof beyond a reasonable doubt in December 2013’s State v. Clifton, the court of appeals eliminated any utility from this middle ground, rendering serious mental illness short of M’Naghten insanity a per se aggravating circumstance
Three-body properties of low-lying Be resonances
We compute the three-body structure of the lowest resonances of Be
considered as two neutrons around an inert Be core. This is an extension
of the bound state calculations of Be into the continuum spectrum. We
investigate the lowest resonances of angular momenta and parities, ,
and . Surprisingly enough, they all are naturally occurring in
the three-body model. We calculate bulk structure dominated by small distance
properties as well as decays determined by the asymptotic large-distance
structure. Both and have two-body Be-neutron d-wave
structure, while has an even mixture of and d-waves. The
corresponding relative neutron-neutron partial waves are distributed among ,
, and d-waves. The branching ratios show different mixtures of one-neutron
emission, three-body direct, and sequential decays. We argue for spin and
parities, , and , to the resonances at 0.89, 2.03, 5.13,
respectively. The computed structures are in agreement with existing reaction
measurements.Comment: To be published in Physical Review
Stock mechanics: a general theory and method of energy conservation with applications on DJIA
A new method, based on the original theory of conservation of sum of kinetic
and potential energy defined for prices is proposed and applied on Dow Jones
Industrials Average (DJIA). The general trends averaged over months or years
gave a roughly conserved total energy, with three different potential energies,
i.e. positive definite quadratic, negative definite quadratic and linear
potential energy for exponential rises (and falls), sinusoidal oscillations and
parabolic trajectories, respectively. Corresponding expressions for force
(impact) are also given. Keywords:Comment: 14 pages, 3 figures, scehudled for IJMPC 17/ issue
Reconstruction of N=1 supersymmetry from topological symmetry
The scalar and vector topological Yang-Mills symmetries on Calabi-Yau
manifolds geometrically define consistent sectors of Yang-Mills D=4,6 N=1
supersymmetry, which fully determine the supersymmetric actions up to twist.
For a CY_2 manifold, both N=1,D=4 Wess and Zumino and superYang-Mills theory
can be reconstructed in this way. A superpotential can be introduced for the
matter sector, as well as the Fayet-Iliopoulos mechanism. For a CY_3 manifold,
the N=1, D=6 Yang-Mills theory is also obtained, in a twisted form. Putting
these results together with those already known for the D=4,8 N=2 cases, we
conclude that all Yang--Mills supersymmetries with 4, 8 and 16 generators are
determined from topological symmetry on special manifolds.Comment: 13 page
A Cephalopod Approach to Rethinking about the Importance of the Bohr and Haldane Effects
This study concerns the physiological implications of the Bohr
and Haldane effects and the buffer values in the blood from the cephalopods
Nautilus pompilius, Octopus macropus, Sepia latimanus, Nototodarus sloani
philippinensis, and Sepioteuthis lessoniana. All species studied except one
(Nautilus) have Bohr and Haldane coefficients numerically higher than unity,
and the two effects were found to be nearly identical in all cases, in accord with
the theoretical prediction of Wyman (1964). However, the functional Haldane
coefficient was significantly lower than the Haldane coefficient in two cases
(Sepia and Sepioteuthis). Buffer values were highest in the two species with the
lowest oxygen requirement (Nautilus and Octopus), whereas the three fast swimmers
studied (Nototodarus, Sepia, and Sepioteuthis) display comparatively low
buffer values. It is concluded that the large Bohr effects seen in four of the five
species may have their primary effect on oxygen loading in the gills
Implementation, demonstration and validation of a user-defined wall-function for direct precipitation fouling in ANSYS Fluent
In a previous paper (Johnsen et al., 2015) and presentation (Johnsen et al.,
2016), we developed and demonstrated a generic modelling framework for the
modelling of direct precipitation fouling from multi-component fluid mixtures
that become super-saturated at the wall. The modelling concept involves the
1-dimensional transport of the fluid species through the turbulent boundary
layer close to the wall. The governing equations include the Reynolds-averaged
(RANS) advection-diffusion equations for each fluid species, and the axial
momentum and energy equations for the fluid mixture. The driving force for the
diffusive transport is the local gradient in the species' chemical potential.
Adsorption mechanisms are not modelled per se, but the time-scale of adsorption
is reflected in the choice of Dirichlet boundary conditions for the depositing
species, at the fluid-solid interface.
In this paper, the modelling framework is implemented as a user-defined
function (UDF) for the CFD software ANSYS Fluent, to act as a wall boundary
condition for mass-transfer to the wall. The subgrid, 1-dimensional formulation
of the model reduces the computational cost associated with resolving the fine
length-scales at which the boundary-layer mass transfer is determined, and
allows for efficient modelling of industry-scale heat exchangers suffering from
fouling.
The current paper describes the modelling framework, and demonstrates and
validates its applicability in a simplified 2D heat exchanger geometry
(experimental and detailed CFD modelling data by P\"a\"akk\"onen et al. (2012,
2016)). By tuning the diffusivity, only, good agreement with the experimental
data and the detailed CFD model was obtained, in terms of area-averaged
deposition rates.Comment: 12th International Conference on CFD in Oil & Gas, Metallurgical and
