High Density out-of-Plane Microprobe Array
MEMS technology has been developed rapidly in the last few years. More and
more special micro structures were discussed in several publications. However,
all of the structures were produced by consist of the three fundamental
structures, which included bridge, cantilever and membrane structures. Even the
more complex structures were no exception. The cantilever with the property of
simple design and easy fabrication among three kinds of fundamental structure,
therefore, it was popular used in the design of MEMS device.Comment: Submitted on behalf of EDA Publishing Association

The Rotating Mass Matrix, the Strong CP Problem and Higgs Decay
We investigate a recent solution to the strong CP problem, obtaining a
theta-angle of order unity, and show that a smooth trajectory of the massive
eigenvector of a rank-one rotating mass matrix is consistent with the
experimental data for both fermion masses and mixing angles (except for the
masses of the lightest quarks). Using this trajectory we study Higgs decay and
find suppression of compared to the standard model
predictions for a range of Higgs masses. We also give limits for flavour
violating decays, including a relatively large branching ratio for the
mode.Comment: 15 pages, 6 figures; improvements to introduction and preliminarie
Mass Hierarchy, Mixing, CP-Violation and Higgs Decay---or Why Rotation is Good for Us
The idea of a rank-one rotating mass matrix (R2M2) is reviewed detailing how
it leads to ready explanations both for the fermion mass hierarchy and for the
distinctive mixing patterns between up and down fermion states, which can be
and have been tested against experiment and shown to be fully consistent with
existing data. Further, R2M2 is seen to offer, as by-products: (i) a new
solution of the strong CP problem in QCD by linking the theta-angle there to
the Kobayashi-Maskawa CP-violating phase in the CKM matrix, and (ii) some novel
predictions of possible anomalies in Higgs decay observable in principle at the
LHC. A special effort is made to answer some questions raised.Comment: 47 pages, 9 figure
A Nonabelian Yang-Mills Analogue of Classical Electromagnetic Duality
The classic question of a nonabelian Yang-Mills analogue to electromagnetic
duality is here examined in a minimalist fashion at the strictly 4-dimensional,
classical field and point charge level. A generalisation of the abelian Hodge
star duality is found which, though not yet known to give dual symmetry,
reproduces analogues to many dual properties of the abelian theory. For
example, there is a dual potential, but it is a 2-indexed tensor
of the Freedman-Townsend type. Though not itself functioning as such,
gives rise to a dual parallel transport, , for the
phase of the wave function of the colour magnetic charge, this last being a
monopole of the Yang-Mills field but a source of the dual field. The standard
colour (electric) charge itself is found to be a monopole of .
At the same time, the gauge symmetry is found doubled from say to
. A novel feature is that all equations of motion,
including the standard Yang-Mills and Wong equations, are here derived from a
`universal' principle, namely the Wu-Yang (1976) criterion for monopoles, where
interactions arise purely as a consequence of the topological definition of the
monopole charge. The technique used is the loop space formulation of Polyakov
(1980).Comment: We regret that, due to a technical hitch, parts of the reference list

Testing a failure surface prediction and deposit reconstruction method for a landslide cluster that occurred during Typhoon Talas (Japan)
Reconstructions of failure surfaces (prior to
potential landslides or after their release), landslide deposits, or other
palaeotopographic features are important for hazard and erosion assessment.
The volumes involved in landslide and failure surfaces constrain the
propagation of a landslide, and knowledge of the past topography helps
us to understand these hazards.
Some methods exist to characterise landslide geometry, but these methods
usually require monitoring information. This study tries to assess the
validity of the sloping local base level (SLBL) method for this purpose. Two
sets of airborne lidar digital elevation models (DEMs) of the Kii Peninsula
(Japan) are used: the first one was acquired before Typhoon Talas, and the
second one was acquired after. A total of 70 deep-seated landslides occurred
during this event between 2 and 5 September 2011.
This study shows that the SLBL method is efficient using either the slope
deformations identifiable on the DEM before the release of the landslide or
a reliable 2.5-D failure surface created by using both DEMs (the 2.5-D
corresponds to a surface which has only one z value for each
xây coordinate; in other words, no true vertical topography or overhang can be
represented perfectly). In addition, this method allows for the reconstruction
of eroded deposits and buried valleys. Most of the volumes estimated are
within ±35 % of the estimation made by Chigira et al. (2013), and
the coefficients of expansion range from 10 % to 25 %. These results show
considerable sensitivity to the parameters used for the reconstruction
of the landslide volume estimations and demonstrate the need for an
efficient and fast tool to reconstruct potential landslide geometries or
histories.</p
