Are Machine Learning Based Intrusion Detection System Always Secure?:An insight into tampered learning

Machine learning is successful in many applications including securing a network from unseen attack. The application of learning algorithm for detecting anomaly in a Network has been fundamental since few years. With increasing use of machine learning techniques it has become important to study to what extent it is good to be dependent on them. Altogether a different discipline called ‘Adversarial Learning’ have come up as a separate dimension of study. The work in this paper is to test the robustness of online machine learning based IDS to carefully crafted packets by attacker called poison packets. The objective is to observe how a remote attacker can deviate the normal behavior of machine learning based classifier in the IDS by injecting the network with carefully crafted packets externally, that may seem normal by the classification algorithm and the instance made part of its future training set. This behavior eventually can lead to a poison learning by the classification algorithm in the long run, resulting in misclassification of true attack instances. This work explores one such approach with SOM and SVM as the online learning based classification algorithms

Eating from the wild: an insight into the indigenous wild edible plants consumed by the Digaru Mishmi tribe of Arunachal Pradesh

Anjaw district is situated at the extreme foothill of eastern himalaya of Arunachal Pradesh, distinctive in its nature by having a rich diversity of wild edible plants rich in nutrition as well as medicinal properties. Ethnically, the Digaru Mishmi tribe (inhabitants) of the district adopted the traditional way of consuming these rich ethnobotanical resources to fulfill their daily nutrition & health care. These plants have traditionally occupied an important position in their socio-cultural, spiritual and health aspects of the rural tribal lives. So, the consumption of wild edible plants as a food source has been an integral part of the indigenous people’s culture. To get an insight into the Digaru Mishmi people’s way of lifestyle, the present study was conducted to explore, identify & document the ethno botany of the Digaru Mishmi people and to record their unique knowledge about wild edible plants. Around 57 species were found & all the plants used by the tribe are tabulated inalphabetical order along with botanical name, vernacular name (Digaru Mishmi), family, parts used, food value and ethnomedicinal uses. Wild edible plants form a good source of protein, fat, vitamins, sugar and minerals requirement of the tribal people to a greater extent. Hence, the paper highlights the identification diversity of wild edible plants andits documentation

α

Let (V,Γ) and (V′,Γ′) be Gamma-Banach algebras over the fields F1 and F2 isomorphic to a field F which possesses a real valued valuation, and (V,Γ)⊗p(V′,Γ′), their projective tensor product. It is shown that if D1 and D2 are α - derivation and α′ - derivation on (V,Γ) and (V′,Γ′) respectively and u=∑1x1⊗y1, is an arbitrary element of (V,Γ)⊗p(V′,Γ′), then there exists an α⊗α′- derivation D on (V,Γ)⊗p(V′,Γ′) satisfying the relation D(u)=∑1[(D1x1)⊗y1+x1⊗(D2y1)] and possessing many enlightening properties. The converse is also true under a certain restriction. Furthermore, the validity of the results ‖D‖=‖D1‖+‖D2‖ and sp(D)=sp(D1)+sp(D2) are fruitfully investigated

First Measurement of the Atomic Electric Dipole Moment of \u3csup\u3e225\u3c/sup\u3eRa

The radioactive radium-225 (225Ra) atom is a favorable case to search for a permanent electric dipole moment. Because of its strong nuclear octupole deformation and large atomic mass, 225Ra is particularly sensitive to interactions in the nuclear medium that violate both time-reversal symmetry and parity. We have developed a cold-atom technique to study the spin precession of 225Ra atoms held in an optical dipole trap, and demonstrated the principle of this method by completing the first measurement of its atomic electric dipole moment, reaching an upper limit of |d(225Ra)|\u3c5.0×10−22  e cm (95% confidence)

Formation of two-dimensional weak localization in conducting Langmuir-Blodgett films

We report the magnetotransport properties up to 7 T in the organic highly conducting Langmuir-Blodgett(LB) films formed by a molecular association of the electroactive donor molecule bis(ethylendioxy)tetrathiafulvalene (BEDO-TTF) and stearic acid CH$_3$(CH$_2$)$_{16}$COOH. We show the logarithmic decrease of dc conductivity and the negative transverse magnetoresistance at low temperature. They are interpreted in the weak localization of two-dimensional (2D) electronic system based on the homogeneous conducting layer with the molecular size thickness of BEDO-TTF. The electronic length with phase memory is given at the mesoscopic scale, which provides for the first time evidence of the 2D coherent charge transport in the conducting LB films.Comment: 5 pages, 1 Table and 5 figure

Cross genera amplification of ginger EST-SSRs in large cardamom using genomic DNA isolated from standardized simplified protocol

323-330Large cardamom (Amomum subulatum Roxb.) is one of the most important cash crops of Sikkim. The issues crippling its production have been largely addressed through improved agronomic practices but efforts for genetic improvement have not been made. Being an orphan crop with regard to its genomic resources, the present study was carried out to standardize DNA isolation protocol for large cardamom using minimal resources and cross amplification of ginger expressed sequence tag (EST) based simple sequence repeat (SSR) markers in large cardamom. The DNA isolation protocol was standardized through various modifications in the general cetyltrimethyl ammonium bromide (CTAB) procedure. The DNA isolated through standardized protocol was of high quality confirmed through both electrophoretic (clear and intact bands) and spectrophotometric studies (A260/A280 ratio 1.68 to 1.97). The isolated DNA of all the six large cardamom samples was employed for PCR studies with 73 EST-SSR primers of ginger, out of which 18 showed cross amplification. Out of 18 primers, only 5 exhibited polymorphism showing maximum of 2 alleles per locus. In total, the PIC ranged from 0 to 0.63. A total of  23 alleles were amplified with average of 1.3 alleles per marker. A null allele marker was also observed. The results indicated low cross amplification rate (24.6%).  DNA isolation protocol standardized in the study can be used across labs for extraction of quality DNA with minimal resources and primers showed cross-amplification may be further used for various molecular studies in large cardamoms
