Good news or bad news, which do you want first? The importance of the sequence and organization of Information for financial decision-making: a neuro-electrical imaging study
Investment decisions are largely based on the information investors received from the target firm. Thaler introduced the hedonic editing framework, in which suggests that integration/segregation of information influence individual's perceived value. Meanwhile, when evaluating the evidence and information in a sequence, order effect and biases have been found to have an impact in various areas. In this research, the influence of the Organization of Information (Integration vs. Segregation) and the Sequence of Information (Negative-Positive order vs. Positive-Negative order) on individual's investment decision-making both at the behavioral level (decision) and neurometrix level (measured by an individual's emotion and Approach Withdraw tendency) was assessed for the three groups of information: a piece of Big Positive Information and a piece of Small Negative Information, a piece of Big Negative Information and a piece of Small Positive Information, and a piece of Small Negative information. The behavioral results, which are an individual's final investment decision, were consistent for all three scenarios. In general, individuals will invest more/retire less when receiving two pieces of information in a Negative-Positive order. However, the neurometric results (Emotional Index, Approach Withdraw Index and results from LORETA) show differences among information groups. An effect of the Sequence of Information and the Organization of Information was found for the different scenarios. The results suggest that in the scenarios that involve large-scale information, the organization of information (Integration vs. Segregation) influences the emotion and Approach Withdraw tendency. The results of this investigation should provide insight for effective communication of information, especially when large-scale information is involved
A Predictive Seesaw Scenario for EDMs
The generation of electric dipole moments (EDMs) is addressed in the
supersymmetric seesaw scenario realized through the exchange of SU(2)_W triplet
states. In particular, we show that the triplet soft-breaking bilinear term can
induce finite contributions to lepton and quark EDMs. Moreover, the peculiar
flavour structure of the model allows us to predict the EDM ratios d_e/d_mu and
d_mu/d_tau only in terms of the neutrino parameters.Comment: 5 pages, uses axodraw.sty. Remarks and few references added. To

Radially restricted linear energy transfer for high-energy protons: A new analytical approach
Radially restricted linear energy transfer (LET) is a basic physical parameter relevant to radiation biology and radiation protection. In this report a convenient method is presented for the analytical computation of this quantity without the need for complicated simulation. The method uses the energy-re-stricted LETL, as recently redefined in a 1993 ICRU draft document and supplements it by a relatively simple term that represents the energy of fast rays lost within distancer from the track core. The method provides a better fit than other models and is valid over the entire range of radial distance from track center to the maximum radial distance traveled by the most energetic secondary electrons.L r computed by this approach differs only a few percent from the values

Limits on the Non-Standard Interactions of Neutrinos from Colliders
We provide an effective Lagrangian analysis of contact non-standard
interactions of neutrinos with electrons, which can be effectively mediated by
extra particles, and examine the associated experimental limits. At present,
such interactions are strongly constrained only for : the bounds are
loose for and absent for . We emphasize the unique role
played by the reaction in providing direct
constraints on such non-standard interactions.Comment: 15 LaTeX pages, 6 postscript figures, uses epsfig. New discussion on

A Visual Analytics Approach to Debugging Cooperative, Autonomous Multi-Robot Systems' Worldviews
Autonomous multi-robot systems, where a team of robots shares information to
perform tasks that are beyond an individual robot's abilities, hold great
promise for a number of applications, such as planetary exploration missions.
Each robot in a multi-robot system that uses the shared-world coordination
paradigm autonomously schedules which robot should perform a given task, and
when, using its worldview--the robot's internal representation of its belief
about both its own state, and other robots' states. A key problem for operators
is that robots' worldviews can fall out of sync (often due to weak
communication links), leading to desynchronization of the robots' scheduling
decisions and inconsistent emergent behavior (e.g., tasks not performed, or
performed by multiple robots). Operators face the time-consuming and difficult
task of making sense of the robots' scheduling decisions, detecting
de-synchronizations, and pinpointing the cause by comparing every robot's
worldview. To address these challenges, we introduce MOSAIC Viewer, a visual
analytics system that helps operators (i) make sense of the robots' schedules
and (ii) detect and conduct a root cause analysis of the robots' desynchronized
worldviews. Over a year-long partnership with roboticists at the NASA Jet
Propulsion Laboratory, we conduct a formative study to identify the necessary
system design requirements and a qualitative evaluation with 12 roboticists. We
find that MOSAIC Viewer is faster- and easier-to-use than the users' current
approaches, and it allows them to stitch low-level details to formulate a
high-level understanding of the robots' schedules and detect and pinpoint the
cause of the desynchronized worldviews.Comment: To appear in IEEE Conference on Visual Analytics Science and

Soft Leptogenesis in Higgs Triplet Model
We consider the minimal supersymmetric triplet seesaw model as the origin of
neutrino masses and mixing as well as of the baryon asymmetry of the Universe,
which is generated through soft leptogenesis employing a CP violating phase and
a resonant behavior in the supersymmetry breaking sector. We calculate the full
gauge--annihilation cross section for the Higgs triplets, including all
relevant supersymmetric intermediate and final states, as well as
coannihilations with the fermionic superpartners of the triplets. We find that
these gauge annihilation processes strongly suppress the resulting lepton
asymmetry. As a consequence of this, successful leptogenesis can occur only for
a triplet mass at the TeV scale, where the contribution of soft supersymmetry
breaking terms enhances the CP and lepton asymmetry. This opens up an
interesting opportunity for testing the model in future colliders.Comment: 17 pages, 5 figures; version accepted for publicatio
