IDSGAN: Generative Adversarial Networks for Attack Generation against Intrusion Detection
As an important tool in security, the intrusion detection system bears the
responsibility of the defense to network attacks performed by malicious
traffic. Nowadays, with the help of machine learning algorithms, the intrusion
detection system develops rapidly. However, the robustness of this system is
questionable when it faces the adversarial attacks. To improve the detection
system, more potential attack approaches should be researched. In this paper, a
framework of the generative adversarial networks, IDSGAN, is proposed to
generate the adversarial attacks, which can deceive and evade the intrusion
detection system. Considering that the internal structure of the detection
system is unknown to attackers, adversarial attack examples perform the
black-box attacks against the detection system. IDSGAN leverages a generator to
transform original malicious traffic into adversarial malicious traffic. A
discriminator classifies traffic examples and simulates the black-box detection
system. More significantly, we only modify part of the attacks' nonfunctional
features to guarantee the validity of the intrusion. Based on the dataset
NSL-KDD, the feasibility of the model is demonstrated to attack many detection
systems with different attacks and the excellent results are achieved.
Moreover, the robustness of IDSGAN is verified by changing the amount of the
unmodified features.Comment: 8 pages, 5 figure
The c-Functions of Noncommutative Yang-Mills Theory from Holography
In this paper we study non-commutative Yang-Mills theory (NCYM) through its
gravity dual. First it is shown that the gravity dual of an NCYM with self-dual
-parameters has a Lagrangian in the form of five-dimensional dilatonic
gravity. Then we use the de-Boer-Verlinde-Verlinde formalism for holographic
renormalization group flows to calculate the coefficient functions in the Weyl
anomaly of the NCYM at low energies under the assumption of potential
dominance, and show that the -theorem holds true in the present case.Comment: 22pp. Totally different method and new results that supercede earlier

Higher bottom and bottom-strange mesons
Motivated by the recent observation of the orbital excitation by
CDF collaboration, we have performed a systematical study of the mass spectrum
and strong decay patterns of the higher and mesons. Hopefully the
present investigation may provide valuable clues to further experimental
exploration of these intriguing excited heavy mesons.Comment: 13 pages, 11 figures, 10 tables. More discussions and references

Charged bottomonium-like states and and the decay
Inspired by the newly observed two charged bottomonium-like states, we
consider the possible contribution from the intermediate and
states to the decay
process, which naturally explains Belle's previous observation of the anomalous
production near the peak of at GeV [K.F. Chen {\it et al}. (Belle Collaboration), Phys. Rev. Lett.
{\bf 100}, 112001 (2008)]. The resulting and distributions agree with Belle's
measurement after inclusion of these states. This formalism also
reproduces the Belle observation of the double-peak structure and its
reflection in invariant mass spectrum of decay.Comment: 5 pages, 5 figures, 4 tables. More contents and discussions adde

The title compound, C12H9N2O2
+·Cl−·2H2O, exhibits a layered structure which is stabilized by intermolecular O—H⋯O, O—H⋯Cl− and N+—H⋯Cl− hydrogen bonds, and π–π interactions (centroid–centroid distances = 3.654 and 3.583 Å). The distances between the molecules are 3.371 and 3.294 Å
MiRNA-145 increases therapeutic sensibility to gemcitabine treatment of pancreatic adenocarcinoma cells.
Pancreatic adenocarcinoma is one of the most leading causes of cancer-related deaths worldwide. Although recent advances provide various treatment options, pancreatic adenocarcinoma has poor prognosis due to its late diagnosis and ineffective therapeutic multimodality. Gemcitabine is the effective first-line drug in pancreatic adenocarcinoma treatment. However, gemcitabine chemoresistance of pancreatic adenocarcinoma cells has been a major obstacle for limiting its treatment effect. Our study found that p70S6K1 plays an important role in gemcitabine chemoresistence. MiR-145 is a tumor suppressor which directly targets p70S6K1 for inhibiting its expression in pancreatic adenocarcinoma, providing new therapeutic scheme. Our findings revealed a new mechanism underlying gemcitabine chemoresistance in pancreatic adenocarcinoma cells
