Gravitationally Coupled Electroweak Monopole
We present a family of gravitationally coupled electroweak monopole solutions
in Einstein-Weinberg-Salam theory. Our result confirms the existence of
globally regular gravitating electroweak monopole which changes to the
magnetically charged black hole as the Higgs vacuum value approaches to the
Planck scale. Moreover, our solutions could provide a more accurate description
of the monopole stars and magnetically charged black holes
Interpersonal Trauma, Adult Attachment, and Self-Compassion: A Relational Model of Shame
The purpose of the present study was to examine the interrelationships among cumulative interpersonal trauma (IPT), the dimensions of adult attachment anxiety and avoidance, self-compassion, and shame based on an integrative theoretical framework in a sample of undergraduate students (N = 310). The results of this structural equation modeling analysis with bootstrapping supported the primary model which showed that higher degrees of exposure to IPT in childhood, adolescence, and the first two years of emerging adulthood directly related to increased levels of attachment anxiety and avoidance as well as decreased levels of self-compassion. The findings further demonstrated that higher levels of attachment anxiety directly related to increased shame, and higher levels of attachment avoidance and self-compassion directly related to decreased shame. Together, these constructs explained over half of the total variance in self-reported shame in the present sample. The results of this study reinforced the powerful potential of considering both intra- and interpersonal postures of relating to inform strengths-based, resiliency-focused, and preventative interventions with young adult survivors of interpersonal trauma who experience shame. Implications for professionals working with these emerging adults are discussed
On the Gauged Non-compact Spin System
We examine classical and quantum aspects of the planar non-compact spin
system coupled with Chern-Simons gauge field in the presence of background
charge. We first define our classical spin system as non- relativistic
non-linear sigma model in which the order parameter spin takes value in the
non-compact manifold . Although the naive model does not
allow any finite energy self dual solitons, it is shown that the gauged system
admits static Bogomol'nyi solitons with finite energy whose rotationally
symmetric soliton solutions are analyzed in detail. We also discuss the large
spin limit in which the self-dual equation reduces to the well-known gauged
non- linear Schr\"odinger model or Abelian Higgs model, depending on the choice
of the background charge term. Then, we perform quantization of the model. We
find that the spin algebra satisfies anomalous commutation relations, and the
system is a field theoretic realization of the anyons.Comment: 21 pages, Latex, 3 figures include
Systemic Lupus Erythematosus in Dogs and Cats
Systemic lupus erythematosus (SLE) is an autoimmune disease affecting multiple systems and has been reported in humans, dogs, and cats. Although known since the 19th century in humans, SLE was not recognized in the dog until 1965. Since the first case report, a number of cases have been documented in the dog. On the other hand, the firs case of SLE to be suspected in a cat was in 1971, and only five further cases have appeared in the literature
Maxwell--Chern-Simons gauged non-relativistic O(3) model with self-dual vortices
A non-relativistic version of the 2+1 dimensional gauged Chern-Simons O(3)
sigma model, augmented by a Maxwell term, is presented and shown to support
topologically stable static self-dual vortices. Exactly like their counterparts
of the ungauged model, these vortices are shown to exhibit Hall behaviour in
their dynamics.Comment: 12 pages, LateX, to appear in Mod. Phys. Lett. 199
Intrinsic Axis Ratio Distribution of Early-type Galaxies From Sloan Digital Sky Survey
Using Sloan Digital Sky Survey Data Release 5, we have investigated the
intrinsic axis ratio distribution (ARD) for early-type galaxies. We have
constructed a volume-limited sample of 3,922 visually-inspected early-type
galaxies at carefully considering sampling biases
caused by the galaxy isophotal size and luminosity. We attempt to de-project
the observed ARD into three-dimensional types (oblate, prolate, and triaxial),
which are classified in terms of triaxiality. We confirm that no linear
combination of -distributed axis ratios of the three types can
reproduce the observed ARD. However, using Gaussian intrinsic distributions, we
have found reasonable fits to the data with preferred mean axis ratios for
oblate, prolate, and triaxial (triaxials in two axis ratios), where the fractions of
oblate, prolate and triaxial types are
\textrm{O:P:T}=0.29^{\pm0.09}:0.26^{\pm0.11}:0.45^{\pm0.13}-23.3 < M_r \leq -21.2-21.2 < M_r <-19.3$) sample does. Oblate is
relatively more abundant among the less luminous galaxies. Interestingly, the
preferences of axis ratios for triaxial types in the two luminosity classes are
remarkably similar. We have not found any significant influence of the local
galaxy number density on ARD. We show that the results can be seriously
affected by the details in the data selection and type classification scheme.
Caveats and implications on galaxy formation are discussed.Comment: 9 pages, 11 figures, Accepted for publication in Ap
