Resonantly-forced Eccentric Ringlets: Relationships between Surface Density, Resonance location, Eccentricity and Eccentricity-gradient
We use a simple model of the dynamics of a narrow-eccentric ring, to put some
constraints on some of the observable properties of the real systems.In this
work we concentrate on the case of the `Titan ringlet of Saturn'.Our approach
is fluid-like, since our description is based on normal modes of oscillation
rather than in individual particle orbits. Thus, the rigid precession of the
ring is described as a global mode, which originates from a standing wave
superposed on an axisymmetric background. An integral balance condition for the
maintenance of the standing-wave can be set up, in which the differential
precession induced by the oblateness of the central planet must cancel the
contributions of self-gravity, the resonant satellite forcing and collisional
effects. We expect that in nearly-circular narrow rings dominated by
self-gravity, the eccentricity varies linearly across the ring. Thus, we take a
first order expansion and we derive two integral relationships from the
rigid-precession condition. These relate the surface density of the ring with
the eccentricity at the center, the eccentricity gradient and the location of
the secular resonance. These relationships are applied to the Titan ringlet of
Saturn, which has a secular resonance with the satellite Titan in which the
ring precession period is close to Titan's orbital period. In this case, we
estimate the mean surface density and the location of the secular resonance.Comment: Accepted for publication in Celestial Mechanics and Dynamical

A Semiotic Analysis on the Perceived Meanings of Coca Cola “Anthem” Video Commercial
This study observes the perceived meanings produced by young adult (18 to 30 years old) and older (50 to 65 years old) respondents as respondents from different age group can produce different perceived meanings from each other. The writer's finding is that in perceiving, young adult respondents tend to emphasize on Coca Cola's emotional roles. On the other hand, the older respondents emphasize on Coca Cola's physical roles
Middle School Teachers\u27 Experiences with Cross-Curricular Connections at the Incident Level
Many curricular innovations, including cross-curricular teaching, are started in schools without adequate teacher preparation and support, reducing the effectiveness of the interventions in supporting student learning. The purpose of this qualitative case study was to describe the implementation of the cross-curricular connections teaching technique in middle schools. Research questions focused on how middle school teachers experienced implementation of cross-curricular teaching at the incident level and how teachers perceived cross-curricular teaching and its long-term value. Myers-Briggs personality type theory informed the study, supporting the postulation that teachers are more comfortable teaching from their personality types. Data from 10 middle school teachers from 3 urban and semirural parochial schools in the northeastern United States were collected through interviews, focus group sessions, journals, and documents such as lesson plans and classroom materials. Open coding was used within progressive and comparative analyses. Primary themes included teacher comfort with cross-curricular connections; various applications of the teaching technique; cross-curricular connections within lessons; time constraints in planning, preparation, and implementation; and creative enhancement of lessons. Recommendations included enhanced professional development, more planning time for teacher teams, and more research about the technique. Positive social change implications include sustaining teachers\u27 adoption and implementation of cross-curricular instruction in support of student achievement
The Spin-Orbit Evolution of GJ 667C System: The Effect of Composition and Other Planet's Perturbations
Potentially habitable planets within the habitable zone of M-dwarfs are
affected by tidal interaction. We studied the tidal evolution in GJ 667C using
a numerical code we call TIDEV. We reviewed the problem of the dynamical
evolution focusing on the effects that a rheological treatment, different
compositions and the inclusion of orbital perturbations, have on the spin-down
time and the probability to be trapped in a low spin-orbit resonance.
Composition have a strong effect on the spin-down time, changing, in some
cases, by almost a factor of 2 with respect to the value estimated for a
reference Earth-like model. We calculated the time to reach a low resonance
value (3:2) for the configuration of 6 planets. Capture probabilities are
affected when assuming different compositions and eccentricities variations. We
chose planets b and c to evaluate the probabilities of capture in resonances
below 5:2 for two compositions: Earth-like and Waterworld planets. We found
that perturbations, although having a secular effect on eccentricities, have a
low impact on capture probabilities and noth- ing on spin-down times. The
implications of the eccentricity variations and actual habitability of the GJ
667C system are discussed.Comment: 15 pages, 9 figures, 4 tables. Accepted for publication in MNRAS - V
Migration and the formation of systems of hot super-Earths and Neptunes
The existence of extrasolar planets with short orbital periods suggests that
planetary migration induced by tidal interaction with the protoplanetary disk
is important. Cores and terrestrial planets may undergo migration as they form.
In this paper we investigate the evolution of a population of cores with
initial masses in the range 0.1-1 earth mass embedded in a disk. Mutual
interactions lead to orbit crossing and mergers, so that the cores grow during
their evolution. Interaction with the disk leads to orbital migration, which
results in the cores capturing each other in mean motion resonances. As the
cores migrate inside the disk inner edge, scatterings and mergers of planets on
unstable orbits together with orbital circularization causes strict
commensurability to be lost. Near commensurability however is usually
maintained. All the simulations end with a population of typically between two
and five planets, with masses depending on the initial mass. These results
indicate that if hot super-Earths or Neptunes form by mergers of inwardly
migrating cores, then such planets are most likely not isolated. We would
expect to always find at least one, more likely a few, companions on close and
often near-commensurable orbits. To test this hypothesis, it would be of
interest to look for planets of a few to about 10 earth masses in systems where
hot super-Earths or Neptunes have already been found.Comment: 29 pages, to be published in Ap
Gynecomastia and Chest Masculinization: An Updated Comprehensive Reconstructive Algorithm
Background: Gynecomastia is a common finding in males. Clinical aspect varies widely in world populations showing peculiar hallmarks according to different body shapes reflecting personal expectations; therefore, a surgical plan must be tailored on individual basis to all type of patients. Materials and Method: A total of 522 patients, treated for bilateral gynecomastia from January 2007 to January 2019, were included and reviewed in this retrospective study. Considering physical status BMI, muscular trophism, hypertrophy of the mammary region, nipple–areola disorder, gland and skin cover consistency, a four-tier classification system has been used to classify the deformity and to assess a surgical plan. In all cases, a subcutaneous mastectomy was performed under direct vision. Results: No recurrence of the deformity was observed as well as major complications such as necrosis, and high level of satisfaction was observed in all groups. No breast cancer was found at the histological examinations Operative time ranged from 25 minutes up to 120 minutes and hospitalization time ranged from 1 to 3 days. Conclusion: Since the physical status is strictly related to the clinical features of the disorder, a comprehensive classification system and a reconstructive algorithm are proposed.

Apse-alignment in narrow-eccentric ringlets and its implications for the EPSILON-ring of Uranus and the ring system of (10199) Chariklo
The discovery of ring systems around objects of the outer Solar System
provides a strong motivation to apply theoretical models in order to better
estimate their physical and orbital parameters, which can constrain scenarios
for their origin. We review the criterion for maintaining apse-alignment across
a ring and the balance between the energy input rate provided by a close by
satellite and the internal dissipation rate occurring through ring particle
collisions that is required to maintain ring eccentricity, as derived from the
equations of motion governing the Lagrangian-displacements of the ring-particle
orbits. We use the case of the epsilon-ring of Uranus, to calibrate our
theoretical discussion and illustrate the basic dynamics governing these types
of ring. In the case of the ring system of (10199) Chariklo, where the evidence
that the rings are eccentric is not conclusive, we apply the theory of
apse-alignment to derive information about the most plausible combination of
values of the surface density and eccentricity-gradient, as well as the masses
and locations of their postulated but -presently
undetected-shepherd-satellites. When the balance conditions that we predict are
applied to the ring system of (10199) Chariklo, we are able to estimate the
minimum mass of a shepherd satellite required to prevent eccentricity decay, as
a function of its orbital location, for two different models of dissipation. We
conclude that the satellite mass required to maintain the m = 1 eccentric mode
in the ring, would be similar or smaller than that needed to confine the rings
radially.Comment: In press in ICARU
