Experimental Validation of Contact Dynamics for In-Hand Manipulation
This paper evaluates state-of-the-art contact models at predicting the
motions and forces involved in simple in-hand robotic manipulations. In
particular it focuses on three primitive actions --linear sliding, pivoting,
and rolling-- that involve contacts between a gripper, a rigid object, and
their environment. The evaluation is done through thousands of controlled
experiments designed to capture the motion of object and gripper, and all
contact forces and torques at 250Hz. We demonstrate that a contact modeling
approach based on Coulomb's friction law and maximum energy principle is
effective at reasoning about interaction to first order, but limited for making
accurate predictions. We attribute the major limitations to 1) the
non-uniqueness of force resolution inherent to grasps with multiple hard
contacts of complex geometries, 2) unmodeled dynamics due to contact
compliance, and 3) unmodeled geometries dueto manufacturing defects.Comment: International Symposium on Experimental Robotics, ISER 2016, Tokyo,

The influence of environmental and core temperature on cyclooxygenase and PGE2 in healthy humans.
Whether cyclooxygenase (COX)/prostaglandin E2 (PGE2) thermoregulatory pathways, observed in rodents, present in humans? Participants (n = 9) were exposed to three environments; cold (20 °C), thermoneutral (30 °C) and hot (40 °C) for 120 min. Core (Tc)/skin temperature and thermal perception were recorded every 15 min, with COX/PGE2 concentrations determined at baseline, 60 and 120 min. Linear mixed models identified differences between and within subjects/conditions. Random coefficient models determined relationships between Tc and COX/PGE2. Tc [mean (range)] increased in hot [+ 0.8 (0.4-1.2) °C; p < 0.0001; effect size (ES): 2.9], decreased in cold [- 0.5 (- 0.8 to - 0.2) °C; p < 0.0001; ES 2.6] and was unchanged in thermoneutral [+ 0.1 (- 0.2 to 0.4) °C; p = 0.3502]. A relationship between COX2/PGE2 in cold (p = 0.0012) and cold/thermoneutral [collapsed, condition and time (p = 0.0243)] was seen, with higher PGE2 associated with higher Tc. A within condition relationship between Tc/PGE2 was observed in thermoneutral (p = 0.0202) and cold/thermoneutral [collapsed, condition and time (p = 0.0079)] but not cold (p = 0.0631). The data suggests a thermogenic response of the COX/PGE2 pathway insufficient to defend Tc in cold. Further human in vivo research which manipulates COX/PGE2 bioavailability and participant acclimation/acclimatization are warranted to elucidate the influence of COX/PGE2 on Tc
Cliophysics: Socio-political Reliability Theory, Polity Duration and African Political (In)stabilities
Quantification of historical sociological processes have recently gained
attention among theoreticians in the effort of providing a solid theoretical
understanding of the behaviors and regularities present in sociopolitical
dynamics. Here we present a reliability theory of polity processes with
emphases on individual political dynamics of African countries. We found that
the structural properties of polity failure rates successfully capture the risk
of political vulnerability and instabilities in which 87.50%, 75%, 71.43%, and
0% of the countries with monotonically increasing, unimodal, U-shaped and
monotonically decreasing polity failure rates, respectively, have high level of
state fragility indices. The quasi-U-shape relationship between average polity
duration and regime types corroborates historical precedents and explains the
stability of the autocracies and democracies.Comment: 4 pages, 3 figures, 1 tabl
Second T = 3/2 state in B and the isobaric multiplet mass equation
Recent high-precision mass measurements and shell model calculations~[Phys.
Rev. Lett. {\bf 108}, 212501 (2012)] have challenged a longstanding explanation
for the requirement of a cubic isobaric multiplet mass equation for the lowest
isospin quartet. The conclusions relied upon the choice of the
excitation energy for the second state in B, which had two
conflicting measurements prior to this work. We remeasured the energy of the
state using the reaction and significantly disagree
with the most recent measurement. Our result supports the contention that
continuum coupling in the most proton-rich member of the quartet is not the
predominant reason for the large cubic term required for nuclei
Development of a toolkit for a mentoring program
The mentoring kit for a mentoring program provides the
mentors with the necessary resources and tools to help to
mentees and teams to understand, apply and integrate their
strengths in their respective roles. The tools of the kit offer a
working model with the mentee to develop an effective strategy
that improves his/her performance through development based
on strengths. One of the most effective methods for managing
and developing talent within students are mentoring programs.
These programs provide a vehicle in which knowledge and
wisdom is shared while creating an environment for learning
and growth. Novice mentors could benefit from a toolkit to help
structure effective mentoring programs. This article describes
such a toolkit to provide mentors with the necessary resources
and tools to help mentees and teams to understand, apply and
integrate their strengths in their respective roles. The objectives
of this toolkit are: 1. Deliver models and structures so that the
mentee has the ability to: - Develop transformational, theoretical
and experiential learning processes. - Develop, evaluate and
optimize your resources to function with greater creativity,
prominence, leadership and proactivity. 2. Stimulate the
development of skills that provide innovative perspectives. 3.
Learn to apply the tools and skills acquired in the educational
field to: - Understand and diagnose situations in context. -
Develop intervention plans with his/her mentor adjusted to the
needs and expectations of themselves. - Generate spaces for the
identification of barriers and conflicts in his/her processes. -
Stimulate actions to overcome challenges or opportunities. –
Effective accompaniment of the mentees to reach their goals.
Additionally, the tools included in the kit offer a working model
for the mentee to develop an effective strategy that improves
his/her performance through development based on strengths.
This article presents the importance of the use of mentoring
tools, under the guidelines of the mentoring toolkit design. This
article presents the importance of the use of mentoring tools,
under the guidelines of the mentoring toolkit design. This paper
reflects simple tools that can be used in a systematic way so that
in the mentoring process the participant can perform the most
difficult task of all, that of investigating themselves and at the
same time the mentor can count on valuable data to be able to
facilitate the work. Future research will focus on the evaluation
of the toolkit
