12 Confused Men: Using Flowchart Verdict Sheets To Mitigate Inconsistent Civil Verdicts
The finality of jury verdicts reflects an implicit societal acceptance of the soundness of the jury\u27s decision. Regardless, jurors are not infallible, and the questions they are often tasked with deciding are unfortunately neither obvious nor clear. The length of trial, complexity of subject matter, volume of factual background, and opaqueness of law can converge in a perfect storm that may confound even the most capable juror. Although the Federal Rules of Civil Procedure provide decision rules to resolve inconsistent verdicts, the current remedies authorized by Rule 49—notably, the resubmission of the verdict to the jury and the ordering of a new trial—impose time and money costs on the jury, litigants, and judicial system. The increasing complexity of civil litigation raises the stakes by increasing the likelihood of juror error and the costs of relitigating the case.
This Note proposes the creation of flowchart verdict sheets as a prophylactic against juror confusion. The flowchart verdict sheet builds upon current legal reform proposals to increase juror understanding while decreasing juror confusion and incorporates principles of effective visual design. By mitigating the confusion that can result in inconsistencies before the verdict is rendered, the flowchart verdict sheet enables the judicial system to avoid the costs associated with remedying inconsistent verdicts
Multiband Emission from Pulsar Wind Nebulae: A Possible Injection Spectrum
A recent research shows that particles with a spectrum of a relativistic
Maxwellian plus a high-energy tail can be accelerated by relativistic
collisionless shocks. We investigate the possibility of the high-energy
particles with this new spectrum injected in pulsar wind nebulae (PWNe) from
the terminate shock based on the study of multiwavelength emission from PWNe.}
{The dynamics of a supernova remnant (SNR) and multiband nonthermal emission
from the PWN inside the remnant are investigated using a dynamical model with
electrons/positrons injected with the new spectrum. In this model, the
dynamical and radiative evolution of a pulsar wind nebula in a non-radiative
supernova remnant can be self-consistently described.} {This model is applied
to the three composite SNRs, G0.9+0.1, MSH 15-52, G338.3-0.0, and the multiband
observed emission from the three PWNe can be well reproduced.} {Our studies on
the three remnant provide evidence for the new spectrum of the particles, which
are accelerated by the terminate shock, injected into a PWN.Comment: 9 pages, 9 figures, accepted by A&

A linear filter is used to estimate a linear combination of the system states. The problem addressed is the design of a filter such that, for all admissible parameter uncertainties, the following three objectives are simultaneously achieved: 1) the filtering process is P-stable, i.e., the poles of the filtering matrix are located inside a parabolic region; 2) the steady-state variance of the estimation error of each state is not more than the individual prespecified value; and 3) the transfer function from exogenous noise inputs to error state outputs meets the prespecified H∞ norm upper-bound constraint. An effective algebraic matrix inequality approach is developed to derive both the existence conditions and the explicit expression of the desired filters. An illustrative example is used to demonstrate the usefulness of the proposed design approach
Bifurcation Boundary Conditions for Switching DC-DC Converters Under Constant On-Time Control
Sampled-data analysis and harmonic balance analysis are applied to analyze
switching DC-DC converters under constant on-time control. Design-oriented
boundary conditions for the period-doubling bifurcation and the saddle-node
bifurcation are derived. The required ramp slope to avoid the bifurcations and
the assigned pole locations associated with the ramp are also derived. The
derived boundary conditions are more general and accurate than those recently
obtained. Those recently obtained boundary conditions become special cases
under the general modeling approach presented in this paper. Different analyses
give different perspectives on the system dynamics and complement each other.
Under the sampled-data analysis, the boundary conditions are expressed in terms
of signal slopes and the ramp slope. Under the harmonic balance analysis, the
boundary conditions are expressed in terms of signal harmonics. The derived
boundary conditions are useful for a designer to design a converter to avoid
the occurrence of the period-doubling bifurcation and the saddle-node
bifurcation.Comment: Submitted to International Journal of Circuit Theory and Applications

Age spreads and the temperature dependence of age estimates in Upper Sco
Past estimates for the age of the Upper Sco Association are typically 11-13
Myr for intermediate-mass stars and 4-5 Myr for low-mass stars. In this study,
we simulate populations of young stars to investigate whether this apparent
dependence of estimated age on spectral type may be explained by the star
formation history of the association. Solar and intermediate mass stars begin
their pre-main sequence evolution on the Hayashi track, with fully convective
interiors and cool photospheres. Intermediate mass stars quickly heat up and
transition onto the radiative Henyey track. As a consequence, for clusters in
which star formation occurs on a similar timescale as the transition from a
convective to a radiative interior, discrepancies in ages will arise when ages
are calculated as a function of temperature instead of mass. Simple simulations
of a cluster with constant star formation over several Myr may explain about
half of the difference in inferred ages versus photospheric temperature;
speculative constructions that consist of a constant star formation followed by
a large supernova-driven burst could fully explain the differences, including
those between F and G stars where evolutionary tracks may be more accurate. The
age spreads of low-mass stars predicted from these prescriptions for star
formation are consistent with the observed luminosity spread of Upper Sco. The
conclusion that a lengthy star formation history will yield a temperature
dependence in ages is expected from the basic physics of pre-main sequence
evolution and is qualitatively robust to the large uncertainties in pre-main
sequence evolutionary models.Comment: 13 pages, accepted by Ap
Understanding Overbidding in Second Price Auctions: An Experimental Study
This paper presents results from a series of second price private value auction (SPA) experiments in which bidders are either given for free, or are allowed to purchase, noisy signals about their opponents' value. Even though theoretically such information about opponents' value has no strategic use in the SPA, it provides us with a convenient instrument to change bidders' perception about the "strength" (i.e., the value) of their opponent. We argue that the empirical relationship between the incidence and magnitude of overbidding and bidders' perception of the strength of their opponent provides the key to understand whether overbidding in second price auctions are driven by "spite" motives or by the "joy of winning." The experimental data show that bidders are much more likely to overbid, though less likely to submit large overbid, when they perceive their rivals to have similar values as their own. We argue that this empirical relationship is more consistent with a modified "joy of winning" hypothesis than with the "spite" hypothesis. However, neither of the non-standard preference explanations are able to fully explain all aspects of the experimental data, and we argue for the important role of bounded rationality. We also find that bidder heterogeneity plays an important role in explaining their bidding behavior.Overbidding, Second price auctions, Spite, Joy of winning, Bounded rationality
Tri-Dirac Surface Modes in Topological Superconductors
We propose a new type of topological surface modes having cubic dispersion in
three-dimensional topological superconductors. Lower order dispersions are
prohibited by the threefold rotational symmetry and time-reversal symmetry.
Cooper pairing in the bulk changes sign under improper rotations, akin
toHe-B. The surface manifestations are a divergent surface density of
states at the Fermi level and isospins that rotate three times as they circle
the origin in momentum space. We propose that Heusler alloys with band
inversion are candidate materials to harbor the novel topological
superconductivity.Comment: Five-page main text plus five-page supplementary materials; three

Nonadiabatic quantum transition-state theory in the golden-rule limit. I. Theory and application to model systems
We propose a new quantum transition-state theory for calculating Fermi's
golden-rule rates in complex multidimensional systems. This method is able to
account for the nuclear quantum effects of delocalization, zero-point energy
and tunnelling in an electron-transfer reaction. It is related to instanton
theory but can be computed by path-integral sampling and is thus applicable to
treat molecular reactions in solution. A constraint functional based on energy
conservation is introduced which ensures that the dominant paths contributing
to the reaction rate are sampled. We prove that the theory gives exact results
for a system of crossed linear potentials and also the correct classical limit
for any system. In numerical tests, the new method is also seen to be accurate
for anharmonic systems, and even gives good predictions for rates in the Marcus
inverted regime.Comment: 18 pages and 6 figure
