Stable Non-BPS States and Their Holographic Duals
Stable non-BPS states can be constructed and studied in a variety of contexts
in string theory. Here we review some interesting constructions that arise from
suspended and wrapped branes. We also exhibit some stable non-BPS states that
have holographic duals.Comment: 10 pages, LaTeX, 10 .eps figures (included); based on a talk given at

Supersymmetric Electromagnetic Waves on Giants and Dual-Giants
We set up the BPS equations for a D3-brane moving in AdS_5 \times S^5 which
preserves two supercharges and with all bosonic fields turned on in the
world-volume theory. By solving these, we find generalizations of Mikhailov
giants and wobbling dual-giants that include electromagnetic waves propagating
on their world-volume. For these giants (dual-giants) we show that the BPS
field strength is the real part of the pull-back of a holomorphic 2-form in the
ambient space C^3 (C^{1,2}) onto the world-volume.Comment: 18 page
Counting 1/8-BPS Dual-Giants
We count 1/8-BPS states in type IIB string theory on AdS_5 x S^5 background
which carry three independent angular momenta on S^5. These states can be
counted by considering configurations of multiple dual-giant gravitons up to N
in number which share at least four supersymmetries. We map this counting
problem to that of counting the energy eigen states of a system of N bosons in
a 3-dimensional harmonic oscillator. We also count 1/8-BPS states with two
independent non-zero spins in AdS_5 and one non-zero angular momentum on S^5 by
considering configurations of arbitrary number of giant gravitons that share at
least four supersymmetries.Comment: 19 page
Exact operator bosonization of finite number of fermions in one space dimension
We derive an exact operator bosonization of a finite number of fermions in
one space dimension. The fermions can be interacting or noninteracting and can
have an arbitrary hamiltonian, as long as there is a countable basis of states
in the Hilbert space. In the bosonized theory the finiteness of the number of
fermions appears as an ultraviolet cut-off. We discuss implications of this for
the bosonized theory. We also discuss applications of our bosonization to
one-dimensional fermion systems dual to (sectors of) string theory such as LLM
geometries and c=1 matrix model.Comment: 47 pages, 1 figure; (v2) typos correcte
Effect of integrated nutrient management on dry herbage yield, nutrient uptake and profitability of French Basil (Ocimum basilicum L.)
Field experiments were conducted at ICAR - Indian Institute of Horticultural Research, Bengaluru during Kharif season of 2015 and 2016 with nine treatments and three replications in a randomized block design to find out the effect of integrated nutrient management on dry herbage yield, nutrient uptake and economics of sweet basil (Ocimum basilicum). The results revealed that the conjunctive use of inorganic fertilizer along with FYM increased the dry herbage yield and nutrient uptake of sweet basil. Application of recommended FYM (10 t/ha) along with recommended NPK (160:80:80 kg/ha) registered the highest dry herbage yield (8.43 and 3.76 t ha- 1) in the main crop and ratoon, respectively and maximum uptake of nutrient in the main crop as N (155.67 and 113.19 kg/ha), P (43.80 and 32.43 kg/ha) and K (163.33 and 116.16 kg/ha) and in ratoon (56.43 and 26.65 kg ha-1), (16.14 and 14.01 kg ha-1) and (55.65 and 39.27 kg ha-1) in 2015 and 2016 respectively. Highest B: C ratio (5.49) was obtained with application of full dose of recommended NPK fertilizer during 2015. While in 2016, the maximum B: C ratio (3.71) was recorded with application of recommended dose of NPK (160:80:80 kg/ha) + FYM (10 t/ha)
