Karakteristik Lahan dan Konstruksi Tabel Kebutuhannya Bagi Pengembangan Atung (Parinarium Glaberimum Hassk) di Negeri Haruku
This research was conducted on sample area where Atung plant grow, focused on the Land âPetuananâ of ââHaruku village in Haruku small Island-Central Maluku Regency, from December 2016 till May 2017. The aims of this research were: 1) to assess the physical characteristics of land affecting the growth and production of Atung plant at the study area; 2) to elaborate the physical essential information and necessary data on the basis of literature and field review in constructing the land suitability table for the Atung Plant (as a preliminary approach); 3) to implement or test the appropriate land suitability table for the land suitability evaluation of Atung based on available biophysical land characteristic data. The method used in this study was a library study and field survey using the distance of flexible transect observation in accordance with the conditions where Atung grows. The results of this study consisted of the land characteristics data for Atung plant; i.e. climate, topography, and soil. The study of land characteristics obtained from the literature, field review and knowledge of the local community and construction of the land suitability table for Atung, an appropriate test in the Waai village showed that the land suitability category as the S3 class with the limiting factor was pH value that was easily improved and upgraded to the suitability class of S2/S1
Effects of disorder in location and size of fence barriers on molecular motion in cell membranes
The effect of disorder in the energetic heights and in the physical locations
of fence barriers encountered by transmembrane molecules such as proteins and
lipids in their motion in cell membranes is studied theoretically. The
investigation takes as its starting point a recent analysis of a periodic
system with constant distances between barriers and constant values of barrier
heights, and employs effective medium theory to treat the disorder. The
calculations make possible, in principle, the extraction of confinement
parameters such as mean compartment sizes and mean intercompartmental
transition rates from experimentally reported published observations. The
analysis should be helpful both as an unusual application of effective medium
theory and as an investigation of observed molecular movements in cell
membranes.Comment: 9 pages, 5 figure

Rupture of multiple parallel molecular bonds under dynamic loading
Biological adhesion often involves several pairs of specific receptor-ligand
molecules. Using rate equations, we study theoretically the rupture of such
multiple parallel bonds under dynamic loading assisted by thermal activation.
For a simple generic type of cooperativity, both the rupture time and force
exhibit several different scaling regimes. The dependence of the rupture force
on the number of bonds is predicted to be either linear, like a square root or
logarithmic.Comment: 8 pages, 2 figure
Systems of subspaces of a unitary space
For a given poset, we consider its representations by systems of subspaces of
a unitary space ordered by inclusion. We classify such systems for all posets
for which an explicit classification is possible.Comment: 20 page
On Arnold's 14 `exceptional' N=2 superconformal gauge theories
We study the four-dimensional superconformal N=2 gauge theories engineered by
the Type IIB superstring on Arnold's 14 exceptional unimodal singularities
(a.k.a. Arnold's strange duality list), thus extending the methods of 1006.3435
to singularities which are not the direct sum of minimal ones. In particular,
we compute their BPS spectra in several `strongly coupled' chambers.
From the TBA side, we construct ten new periodic Y-systems, providing
additional evidence for the existence of a periodic Y-system for each isolated
quasi-homogeneous singularity with (more generally, for each N=2
superconformal theory with a finite BPS chamber whose chiral primaries have
dimensions of the form N/l).Comment: 73 pages, 7 figure
Categorical Tinkertoys for N=2 Gauge Theories
In view of classification of the quiver 4d N=2 supersymmetric gauge theories,
we discuss the characterization of the quivers with superpotential (Q,W)
associated to a N=2 QFT which, in some corner of its parameter space, looks
like a gauge theory with gauge group G. The basic idea is that the Abelian
category rep(Q,W) of (finite-dimensional) representations of the Jacobian
algebra should enjoy what we call the Ringel
property of type G; in particular, rep(Q,W) should contain a universal
`generic' subcategory, which depends only on the gauge group G, capturing the
universality of the gauge sector. There is a family of 'light' subcategories
, indexed by points , where
is a projective variety whose irreducible components are copies of
in one--to--one correspondence with the simple factors of G.
In particular, for a Gaiotto theory there is one such family of
subcategories, , for each maximal degeneration of
the corresponding surface , and the index variety may be identified
with the degenerate Gaiotto surface itself: generic light subcategories
correspond to cylinders, while closed-point subcategories to `fixtures'
(spheres with three punctures of various kinds) and higher-order
generalizations. The rules for `gluing' categories are more general that the
geometric gluing of surfaces, allowing for a few additional exceptional N=2
theories which are not of the Gaiotto class.Comment: 142 pages, 8 figures, 5 table
