Hierarchical Mass Matrices in a Minimal SO(10) Grand Unification I
We consider a minimal SO(10) unified model with horizontal Peccei-Quinn
symmetry. The hierarchical structure of quark-lepton mass matrices is naturally
implemented by the remnants of certain irrelevant terms. Georgi-Jarlskog
relations are also realized due to the horizontal symmetry.Comment: phyzzx and tables, 15 pages, KUNS 125
The Interplay of Metaphor and Iconicity: A Cognitive Approach to Poetic Texts
This essay attempts to clarify the interrelationship between the notions of metaphor and iconicity in the theory of cognitive metaphor, particularly in the model of ‘blending’ (Turner and Fauconnier 1995, in press, Fauconnier and Turner 1996, Turner 1996, 1998, among others). In cognitive and semiotic terms, ‘icons’ and ‘metaphors’ share that property of signification ‘motivated’ by similarity. Connecting things of similarity is one of the basic operations of the human mind. The treatment of metaphor and iconicity in an interrelated fashion will provide a more cohesive and integrated explanation of various linguistic phenomena. The list of such phenomena includes word formation, word order, grammaticalisation, semantic change, poetic discourse, signed languages and writing systems, as manifestations of the interplay between metaphor and iconicity. This study shows that poetic texts, in particular, serve as an optimal example in this exploration because in poetic discourse, the interplay of metaphor and iconicity is foregrounded rather than backgrounded as in everyday discourse (Jakobson and Waugh 1979). This paper, therefore, aims to contribute in the following two issues. Firstly, theoretical clarification of the interplay of metaphor and iconicity will be given in cognitive terms. Particularly, with the model of blending, we can specify which part(s) of the metaphorical process - whether the input, generic, or blended spaces - relate(s) to the iconic mapping of form and meaning. Secondly, the analysis will demonstrate how the interplay of metaphor and iconicity is manifested in linguistic signs in general, and in poetic texts in particular. It will be claimed that there are two major types of manifestation: (i) that there are iconic moments in metaphor; and (ii) that a form acquires an iconic meaning via metaphor
HCN to HCO^+ Millimeter Line Diagnostics of AGN Molecular Torus I : Radiative Transfer Modeling
We explore millimeter line diagnostics of an obscuring molecular torus
modeled by a hydrodynamic simulation with three-dimensional nonLTE radiative
transfer calculations. Based on the results of high-resolution hydrodynamic
simulation of the molecular torus around an AGN, we calculate intensities of
HCN and HCO^{+} rotational lines as two representative high density tracers.
The three-dimensional radiative transfer calculations shed light on a
complicated excitation state in the inhomogeneous torus, even though a
spatially uniform chemical structure is assumed. Our results suggest that HCN
must be much more abundant than HCO^{+} in order to obtain a high ratio
() observed in some of the nearby galaxies. There is a
remarkable dispersion in the relation between integrated intensity and column
density, indicative of possible shortcomings of HCN(1-0) and HCO^{+}(1-0) lines
as high density tracers. The internal structures of the inhomogeneous molecular
torus down to subparsec scale in external galaxies will be revealed by the
forthcoming Atacama Large Millimeter/submillimeter Array (ALMA). The
three-dimensional radiative transfer calculations of molecular lines with
high-resolution hydrodynamic simulation prove to be a powerful tool to provide
a physical basis for molecular line diagnostics of the central regions of
external galaxies.Comment: 29 pages, 13 figures, Accepted for publication in ApJ, For high

Tree adjunct grammars
In this paper, a tree generating system called a tree adjunct grammar is described and its formal properties are studied relating them to the tree generating systems of Brainerd (Information and Control 14 (1969), 217–231) and Rounds (Mathematical Systems Theory 4 (1970), 257–287) and to the recognizable sets and local sets discussed by Thatcher (Journal of Computer and System Sciences 1 (1967), 317–322; 4 (1970), 339–367) and Rounds. Linguistic relevance of these systems has been briefly discussed also
Status and Tenure for Academic Law Librarians: A Survey
The debate surrounding the issue of faculty and academic status for librarians has captured the attention of contributors to library literature for many years. This ongoing concern eventually led to collective action: in 1959, a report of the University Libraries Section of the Academic Status Committee of the Association of College and Research Libraries (ACRL) “strongly recommended” professional librarians be granted academic status and privileges. Opinion pieces have since abounded, with some convinced that the perceived benefits attached to “faculty status” are the due of the librarian, while others are just as strongly convinced that “status” too often comes with added responsibilities and few rewards.
In June 2001, the ACRL board reaffirmed a statement supporting the granting of faculty status for librarians. The 2001 ACRL statement reinforces the view that faculty status for librarians is a double-edged sword. If this statement is applied by universities or law schools, librarians will find themselves being evaluated alongside their teaching faculty colleagues. Full-time jobs and lack of release time and funding for research activities put librarians at a disadvantage when being evaluated in a large faculty pool, and they may find themselves trying to satisfy two sets of criteria: those relating to their primary job performance as librarians and those needed to meet “faculty” standards.
The law librarians at Texas Tech School of Law Library do not now have faculty or other professional status. In considering whether to seek such status, some discussion among the librarians ensued as to whether they would benefit. In order to make a determination regarding this question, a nationwide survey was conducted to assess the current state of law librarian status and tenure, with results which may have considerable value to universities and colleges considering granting faculty status to their librarians
Analysis of Patients Visiting Niigata University Medical and Dental Hospital with Chief Complaints of Metal Allergy And/or Focal Infection in the Previous 8 Years
Dental metal allergy and dental focal infection are possible causes of dermatological diseases, but have been the subjects of few reports to date. We have been treating such patients in our special clinic for more than 20 years.The purpose of the present study was to investigate the mouths of patients visiting our dental hospital over an 8-year period, with the aim of clarifying whether dental metal allergy and/or dental focal infection affects their dermatologic conditions.We surveyed all clinical records of the 185 patients who visited Niigata University Medical and Dental Hospital with chief complaints of dental metal allergy since 2002. Diagnostics of skin diseases, periodontal records, periapical lesions, dental caries, dental metal series patch test results and Electron Probed Micro-Analysis (EPMA) data were investigated. Ninety-two (49%) patients were suffering from pustulosis palmaris et plantaris and 20 (11%) patients had lichen planus. Eighty-two (49%) patients showed positive reactions on patch testing. Based on the result of patch tests, Ni showed the highest positivity rate (62%, 51 patients), but on EPMA, the number of patients with Ni as an allergen was 14 (27%). On the other hand, more than 98% of patients who showed positive reactions on patch test to Pd and Au had these metals in their dental prostheses. In addition, 112 (60%) patients showed the possibility of dental focal infection
Axial Anomaly and Transition Form Factors
We investigate the properties of the amplitude induced by the anomaly. In a
relatively high energy region those amplitudes are constructed by the vector
meson poles and the anomaly terms, in which the anomaly terms can be
essentially evaluated by the triangle quark graph. We pay our attention to the
anomaly term and make intensive analysis of the existing experimental data,
i.e., the electromagnetic and transition form factors. Our
result shows that it is essential to use the constituent quark mass instead of
the current quark mass in evaluating the anomaly term from the triangle graph.Comment: LaTeX, 14 pages + 4 figures, (figures are included as uuencoded

Solvable Optimal Velocity Models and Asymptotic Trajectory
In the Optimal Velocity Model proposed as a new version of Car Following
Model, it has been found that a congested flow is generated spontaneously from
a homogeneous flow for a certain range of the traffic density. A
well-established congested flow obtained in a numerical simulation shows a
remarkable repetitive property such that the velocity of a vehicle evolves
exactly in the same way as that of its preceding one except a time delay .
This leads to a global pattern formation in time development of vehicles'
motion, and gives rise to a closed trajectory on -
(headway-velocity) plane connecting congested and free flow points. To obtain
the closed trajectory analytically, we propose a new approach to the pattern
formation, which makes it possible to reduce the coupled car following
equations to a single difference-differential equation (Rondo equation). To
demonstrate our approach, we employ a class of linear models which are exactly
solvable. We also introduce the concept of ``asymptotic trajectory'' to
determine and (the backward velocity of the pattern), the global
parameters associated with vehicles' collective motion in a congested flow, in
terms of parameters such as the sensitivity , which appeared in the original
coupled equations.Comment: 25 pages, 15 eps figures, LaTe
The action of CGRP and SP on cultured skin fibroblasts
Calcitonin gene-related peptide (CGRP) is the most abundant neuropeptide in the skin, followed by substance P (SP), vasoactive intestinal peptide (VIP), and other neuropeptides in smaller amounts. the proliferative effect of neuropeptides on fibroblasts may affect wound healing and may be associated with hyperproliferative skin and mesenchymal disorders. Understanding the neuropeptidergic action on fibroblasts may provide relevant information to a deeper comprehension of the healing process. This study reviews the action of the main neuropeptides, CGRP and SP, on cultured human skin fibroblasts.A systematic literature search was conducted on Medline and Web of Science databases on December 21, 2013.A total of 74 articles were retrieved using the proposed search strategies and 3 were found in the references section of the selected articles. Thirteen of the retrieved articles studied the action of CGRP and SP on cultured human skin fibroblasts, 12 of which related to SP and 1 related to both CGRP and SP.Only one study was retrieved about the action of both CGRP and SP on cultured human skin fibroblasts. Further studies are necessary to investigate CGRP on skin fibroblasts and its role in the fibroplasia phase of wound healing.Universidade Federal de São Paulo Unifesp, Dept Surg, Plast Surg Div, Postgrad Program Translat Surg, BR-04024002 São Paulo, BrazilUniv Estadual Santa Cruz, Dept Agr & Environm Sci, BR-45662900 Ilheus, BA, BrazilUniv Estadual Santa Cruz, Dept Biol Sci, BR-45662900 Ilheus, BA, BrazilUniversidade Federal de São Paulo Unifesp, Dept Surg, Plast Surg Div, Postgrad Program Translat Surg, BR-04024002 São Paulo, BrazilWeb of Scienc
