How Not to Combine RC4 States
No full textOver the past few years, an attractive design paradigm has emerged, that aims to produce new stream cipher designs, by combining one or more independently produced RC4 states. The ciphers so produced turn out to be faster than RC4 on any software platform, mainly because the average number of internal operations used in the cipher per byte of keystream produced is usually lesser than RC4. One of the main efforts of the designers is to ensure that the existing weaknesses of RC4 are not carried over to the new ciphers so designed. In this work we will look at two such ciphers RC4B (proposed by Zhang et. al.) and Quad-RC4/m-RC4 (proposed by Maitra et. al.). We will propose distinguishing attacks against all these ciphers, and look at certain design flaws that made these ciphers vulnerable
Caste, class and family structure in West Bengal villages
No full textAnalysis of household survey data collected from three villages of West Bengal, India, shows that caste status continues to be significantly related to structure. However, class status - whether based on occupation or landownership - has a stronger & statistically more significant relationship with family structure. Further analysis shows that both occupational classes & caste structure are strongly related to landownership & also show statistically significant relationships with each other. It appears that it is because of their strong relationship with landownership that occupational classes & caste structure maintain significant relationships with family structure. 7 Tables, 22 References.

Nuclear and joint family households in West Bengal villages
No full textExamines whether nuclear family households are gaining ground in India at the expense of joint family households, based on a questionnaire survey of all 544 households of 3 villages in the Arambagh region of the Hooghly District of West Bengal. The findings suggest that: (1) although the joint family household is not the typical household in rural West Bengal, either in terms of its proportion among all households or in terms of people belonging to it, it shows a remarkable stability, & thus provides support to the cyclical view that joint family households are relatively stable in their rate of incidence, & nuclear family households are transitional forms in the normal functioning of the developmental cycle of joint family units; (2) the developmental cycle of formation & dissolution of joint family households varies by different groups in a village in that the proportion of joint family households tends to be significantly higher among household heads who are age 45+, own land, operate large farms, follow agricultural occupations, belong to high or middle castes, &/or are literate, than among those who are age 44 or younger, landless, operate smaller farms, follow nonagricultural occupations, belong to low castes, or are illiterate; (3) only four characteristics - age, landownership, occupation, & literacy - are independently related to the incidence of household types, & they show a stronger relationship to household types when combined into an index than does each characteristic, except age, related singly; & (4) once the household head is age 45+, regardless of his other characteristics, & his first son is old enough to bring his wife into the household, his probability of heading a joint family increases significantly. The high proportion of nuclear family households in the 3 villages suggest that married sons tend to separate from their parental households almost immediately after they themselves become parents. The joint family household, however, persists as a unit for a relatively longer period of time after it comes into existence among those people in a village who own land, follow agricultural occupations, & are literate. 7 Tables, 16 References.

Reply on the comments on the paper “evidence of fluvial to marine transition in the siwalik rocks of the itanagar area, arunachal pradesh, india: Implication for the regional paleogeography” by mullick & sinha 2024, himalayan geology, 45(1), 138-154
No full textWe welcome the comments by Chakraborty et al. on our paper and acknowledge them for their great time and effort for reading our article so thoroughly and to provide their precious suggestions. Here, we reply to the doubts and queries raised by them for clarification, most of which possibly arise due to misinterpretation of our data. We hereby respond to the queries about the technical issues, facies, drainage system and sedimentological interpretation and in reply would definitely like to answer some of their logical queries in light of sedimentological overview and our field observations, keeping in mind not to substantiate the credibility of Indian sedimentologists in front of international researchers. We would like to address the comments in a pointwise manner to make the writing more straight-forward and to-the-point
Odor reception in antenna and antennal lobe of Drosophila
No full textIn early years of neurogenetics of Drosophila, most of us were inclined to believe that behavior of the fruit fly is largely stereotyped and hard-wired. This, at least, was a common prejudice when genetic analysis of olfaction began. We now know that Drosophila like other insects is capable of several types of learning or experience-dependent modification of behavior
f(R) gravity solutions for evolving wormholes
No full textAbstract The scalar–tensor f(R) theory of gravity is considered in the framework of a simple inhomogeneous space-time model. In this research we use the reconstruction technique to look for possible evolving wormhole solutions within viable f(R) gravity formalism. These f(R) models are then constrained so that they are consistent with existing experimental data. Energy conditions related to the matter threading the wormhole are analyzed graphically and are in general found to obey the null energy conditions (NEC) in regions around the throat, while in the limit f ( R ) = R , NEC can be violated at large in regions around the throat
