Sidereal anisotropies in the median rigidity range 60-600GV in 1978-1983
Observed sidereal variations are corrected for the influence of spurious variation by a method using the antisidereal diurnal variations produced from the same 2nd order anisotropy (Nagashima, et al., 1983). It is demonstrated that the corrected variations are a resultant product of two constituents of galactic origin: one is north-south (N-S) symmetric and the other is N-S asymmetric
On the vacuum of the minimal nonsupersymmetric SO(10) unification
We study a class of nonsupersymmetric SO(10) grand unified scenarios where
the first stage of the symmetry breaking is driven by the vacuum expectation
values of the 45-dimensional adjoint representation. Three decade old results
claim that such a Higgs setting may lead exclusively to the flipped SU(5) x
U(1) intermediate stage. We show that this conclusion is actually an artifact
of the tree level potential. The study of the accidental global symmetries
emerging in various limits of the scalar potential offers a simple
understanding of the tree level result and a rationale for the drastic impact
of quantum corrections. We scrutinize in detail the simplest and paradigmatic
case of the 45_{H} + 16_{H} Higgs sector triggering the breaking of SO(10) to
the standard electroweak model. We show that the minimization of the one-loop
effective potential allows for intermediate SU(4)_C x SU(2)_L x U(1)_R and
SU(3)_c x SU(2)_L x SU(2)_R x U(1)_{B-L} symmetric stages as well. These are
the options favoured by gauge unification. Our results, that apply whenever the
SO(10) breaking is triggered by , open the path for hunting the simplest
realistic scenario of nonsupersymmetric SO(10) grand unification.Comment: 22 pages, 1 figure. Refs added. To appear in Phys. Rev.
Treatment of a patient with skeletal open bite and temporomandibular joint disorders
The treatment of severe skeletal anterior open bite is extremely difficult in adults, and orthognathic surgery is generally selected for its treatment. We report the case of an 18-year-old adult patient with skeletal anterior open bite and temporomandibular disorders who was successfully treated using temporary anchorage devices. She had an open bite of -2.0 mm and an increased facial height. Miniplates were implanted in both the maxilla and mandible, and molar intrusion resulted in counterclockwise rotation of the mandible over a period of 12 months. After active treatment, her upper and lower first molars were intruded by approximately 2 mm and her overbite became +2.5 mm. Her retrognathic profile improved with counterclockwise rotation of the mandible. Orthodontic treatment aided with skeletal anchorage is beneficial for intrusion of bimaxillary molars in patients with anterior open bite

Effectiveness of PNAM on nasal form
Objectives: To evaluate the effectiveness of pre-surgical nasoalveolar molding (PNAM) in patients with unilateral cleft lip nasal deformities.
Methods: This was a retrospective study involving 29 patients with unilateral cleft lip and palate defects, of whom 13 were treated with palatal devices with nasal stents (PNAM group) and 16 were treated with palatal devices without nasal stents or surgical tapes (control group). Submental oblique photographs and orthodontic models were longitudinally obtained at the initial visit (T1) and immediately before (T2) and after cheiloplasty (T3). Asymmetry of the external nose, degree of columellar shifting, nasal tip/ala nose ratio, nasal base angle, interalveolar gap, and the sagittal difference in the alveolar gap were measured. The study was conducted in the Orthodontic Clinic at Tokushima University Hospital, Tokushima, Japan between 1997 and 2012.
Results: At T1, there were no significant intergroup differences in the first 4 asymmetry parameters. At T2, the PNAM group showed a significant improvement in all values compared to the control group. At T3, the PNAM group showed significant improvement in nasal asymmetry and columellar shifting. Model analysis showed significantly greater changes in the inter-alveolar gap and the sagittal difference of the alveolar cleft gap from T1 to T2 in the PNAM group.
Conclusion: The use of PNAM is indispensable for pre-surgical orthodontic treatment at the early postnatal age
Spectroscopic factors for bound s-wave states derived from neutron scattering lengths
A simple and model-independent method is described to derive neutron
single-particle spectroscopic factors of bound s-wave states in nuclei from neutron scattering lengths. Spectroscopic factors
for the nuclei ^{13}C, ^{14}C, ^{16}N, ^{17}O, ^{19}O, ^{23}Ne, ^{37}Ar, and
^{41}Ar are compared to results derived from transfer experiments using the
well-known DWBA analysis and to shell model calculations. The scattering length
of ^{14}C is calculated from the ^{15}C_{g.s.} spectroscopic factor.Comment: 9 pages (uses revtex), no figures, accepted for publication in PRC,

Observation by an Air-Shower Array in Tibet of the Multi-TeV Cosmic-Ray Anisotropy due to Terrestrial Orbital Motion Around the Sun
We report on the solar diurnal variation of the galactic cosmic-ray intensity
observed by the Tibet III air shower array during the period from 1999 to 2003.
In the higher-energy event samples (12 TeV and 6.2 TeV), the variations are
fairly consistent with the Compton-Getting anisotropy due to the terrestrial
orbital motion around the sun, while the variation in the lower-energy event
sample (4.0 TeV) is inconsistent with this anisotropy. This suggests an
additional anisotropy superposed at the multi-TeV energies, e.g. the solar
modulation effect. This is the highest-precision measurement of the
Compton-Getting anisotropy ever made.Comment: 4 pages, 2 figures, includes .bbl fil
