The present research article relates to the discovery of the novel drugs based on Zonisamide to treatment of autism disease. In first step, the electronic properties, reactivity and stability of the said compound are discussed. To attain these properties, the said molecular structure is optimized using B3LYP/6-311++G(d,p) level of theory at room temperature. The frontier molecular orbitals (FMO...

OF THE THESIS Properties of LDGM-LDPC codes With Applications to Secrecy Coding by Manik Raina Thesis Directors: Professor Predrag Spasojević The ensemble of low-density generator-matrix/low-density parity-check (LDGM-LDPC) codes has been proposed in literature. In this thesis, an irregular LDGM-LDPC code is studied as a sub-code of an LDPC code with some randomly punctured outputbits. It is sh...

This paper focuses on finite-dimensional upper and lower bounds on decodable thresholds assuming iterative decoding. Two noise measures will be considered: the Bhattacharyya noise parameter, and the expected soft bit of the considered channel. An iterative m-dimensional lower bound is derived for Zm LDPC codes in symmetric channels, which gives a sufficient stability condition for Zm LDPC codes...

The symmetric linear deterministic interference channel (LD-IC) with partial feedback is considered. Partial feedback for the symmetric LD-IC models a scenario in which the top l most-significant-bits of the channel output of receiver j are received as feedback at transmitter j, for j = 1, 2. It is shown that the LD-IC with partial feedback can serve as a good approximation to the Gaussian inte...

methadone is widely being used for opioid substitution therapy. however, the administration of methadone to opioid dependent individual is frequently accompanied by withdrawal syndrome and chemical dependency develops. other than that, it is also difficult to retain patients in the treatment programme making their retention rates are decreasing over time. this article is written to higlights th...

We analyze physical-layer security based on the premise that the coding mechanism for secrecy over noisy channels is tied to the notion of resolvability. Instead of considering capacity-based constructions, which associate to each message a sub-code that operates just below the capacity of the eavesdropper’s channel, we consider resolvability-based constructions, which associate to each message...

The title compound, C(20)H(16)Cl(2)O(2)Se(2), utilizes the symmetry of the crystallographic inversion center. Mol-ecular chains are formed through symmetric C-H⋯Cl inter-actions around inversion centers, mimicking the commonly observed symmetric hydrogen-bonded dimer pattern often found in carboxylic acids.

This paper focuses on finite-dimensional upper and lower bounds on decodable thresholds of Zm and binary lowdensity parity-check (LDPC) codes, assuming belief propagation decoding on memoryless channels. A concrete framework is presented, admitting systematic searches for new bounds. Two noise measures are considered: the Bhattacharyya noise parameter and the soft bit value for a maximum a post...

The authors explore the information leakage in a continuous-variable communication protocol quantum key distribution due to asymmetry of protocol. proposed symmetric minimum-leakage heralding asymptotically eliminates pure-loss channel and minimizes noisy channel.
