Superconformal Black Hole Quantum Mechanics
In recent work, the superconformal quantum mechanics describing D0 branes in
the AdS_2xS^2xCY_3 attractor geometry of a Calabi-Yau black hole with D4 brane
charges p^A has been constructed and found to contain a large degeneracy of
chiral primary bound states. In this paper it is shown that the asymptotic
growth of chiral primaries for N D0 branes exactly matches the
Bekenstein-Hawking area law for a black hole with D4 brane charge p^A and D0
brane charge N. This large degeneracy arises from D0 branes in lowest Landau
levels which tile the CY_3xS^2 horizon. It is conjectured that such a multi-D0
brane CFT1 is holographically dual to IIA string theory on AdS_2xS^2xCY_3.Comment: 8 page
Molecular Responses of Groundnut (Arachis hypogea L.) to Zinc Stress
Heavy metals are important environmental pollutants and their toxicity is a problem of increasing significance for ecological, evolutionary and environmental reasons. The interference of germination related proteins by heavy metals has not been well documented at the proteomic and genomic level. In the current study, molecular responses of germinating groundnut seeds were investigated under Zinc stress. The SDS-PAGE showed the preliminary changes in the polypeptides patterns under Zinc stress. Restriction digestion banding pattern of EcoRI and Hind III enzymes showed distinct banding pattern in the treated plants
On Instantons and Zero Modes of N=1/2 SYM Theory
We study zero modes of N=1/2 supersymmetric Yang-Mills action in the
background of instantons. In this background, because of a quartic antichiral
fermionic term in the action, the fermionic solutions of the equations of
motion are not in general zero modes of the action. Hence, when there are
fermionic solutions, the action is no longer minimized by instantons. By
deforming the instanton equation in the presence of fermions, we write down the
zero mode equations. The solutions satisfy the equations of motion, and
saturate the BPS bound. The deformed instanton equations imply that the finite
action solutions have U(1) connections which are not flat anymore.Comment: 9 pages, latex file, added references, minor change
ANALISIS MUTU GARAM MASAK TRADISIONAL PADA KELOMPOK TIBERIAS DI KELURAHAN OESAPA BARAT, KOTA KUPANG
Abstrak - Garam merupakan salah satu kebutuhan pelengkap dari kebutuhan pangan dan merupakan sumber elektrolit bagi tubuh manusia. Kelompok usaha garam Tiberias merupakan salah satu kelompok usaha garam yang terletak di Kelurahan Oesapa Barat Kecamatan Kelapa Lima Kota Kupang. Tujuan dari penelitian ini yaitu untuk mengetahui kadar air, natrium klorida (NaCl), iodium, magnesium (Mg) dan kalsium (Ca), pada garam masak tradisional di Kelompok Tiberias, Kelurahan Oesapa Barat, Kota Kupang. Penelitian dilaksanakan pada bulan April-Mei 2021. Penelitian ini menggunakan metode kualitatif dan kuantitatif dengan analisis data menggunakan metode deskriptif komparatif. Untuk pengujian kadar air, natrium klorida (NaCl), iodium, magnesium (Mg) dan kalsium (Ca) dilakukan pada Laboratorium PT. Saraswanti Indo Genetech, Bogor. Hasil penelitian menunjukkan bahwa kadar air memenuhi SNI 3556-2016 dan SNI 4435-2017, kadar NaCl belum memenuhi SNI 3556-2016 tetapi memenuhi SNI 4435-2017 dan tergolong pada garam K2 (garam kualitas sedang), kadar iodium tidak memenuhi SNI 3556-2016, kadar magnesium sebesar 183,71 mg/100 g dan kadar kalsium sebesar 503,70 mg/100 g. Kesimpulannya adalah teknik pembuatan garam masak menggunakan alat tradisonal yaitu garam krosok sebanyak 18 kg, air tawar 100 liter dicampur dengan garam krosok, penyaringan berlangsung selama ±1 jam, pemasakan selama ±6-7 jam, penirisan garam berlangsung selama ±5 jam, dan pengemasan garam kedalam karung berkapasitas 50 kg dan kualitas garam yang diproduksi.

D0-branes in Black Hole Attractors
Configurations of N probe D0-branes in a Calabi-Yau black hole are studied. A
large degeneracy of near-horizon bound states are found which can be described
as lowest Landau levels tiling the horizon of the black hole. These states
preserve some of the enhanced supersymmetry of the near-horizon AdS_2xS^2xCY
attractor geometry, but not of the full asymptotically flat solution.
Supersymmetric non-abelian configurations are constructed which, via the Myers
effect, develop charges associated with higher-dimensional branes wrapping CY
cycles. An SU(1,1|2) superconformal quantum mechanics describing D0-branes in
the attractor geometry is explicitly constructed.Comment: 27 page

Comments on Gluino Condensates in N=1/2 SYM Theory
Using Ward identities of N=1/2 supersymmetric Yang-Mills theory, we show that
while the partition function and antichiral gluino condensates remain invariant
under the deformation, chiral gluino correlators can get contributions from
all gauge fields with instanton numbers . In particular, a Ward
identity of the symmetry allows us to determine the explicit
dependence of chiral gluino correlators on the deformation parameter.Comment: 11 pages, 4 figures, small changes, added a referenc
