MacWilliams Identities for Terminated Convolutional Codes [PDF]

open access: yes, 2010
Shearer and McEliece [1977] showed that there is no MacWilliams identity for the free distance spectra of orthogonal linear convolutional codes. We show that on the other hand there does exist a MacWilliams identity between the generating functions of ...

Protective and ameliorative effects of Curcumin and/or Quercetin against gentamicin induced testicular damage in rats

open access: yesSVU-International Journal of Veterinary Sciences, 2023
The aminoglycoside Gentamicin is a commonly used antibiotic counteracting the Gram-ve microorganisms. Rats administered with Gentamicin showing a reduced testicular weight and inhibited spermatogenesis, as gentamicin generates ROS, decreasing the ...

Ionization near-zones associated with quasars at z ~ 6 [PDF]

open access: yes, 2010
We analyze the size evolution of HII regions around 27 quasars between z=5.7 to 6.4 ('quasar near-zones' or NZ). We include more sources than previous studies, and we use more accurate redshifts for the host galaxies, with 8 CO molecular line redshifts ...

Some Properties of Normalized Tails of Maclaurin Power Series Expansions of Sine and Cosine

open access: yesFractal and Fractional
In the paper, the authors introduce two notions, the normalized remainders, or say, the normalized tails, of the Maclaurin power series expansions of the sine and cosine functions, derive two integral representations of the normalized tails, prove the ...

Two particle model for studying the effects of space-charge force on strong head-tail instabilities

open access: yesPhysical Review Accelerators and Beams, 2016
In this paper, we present a new two particle model for studying the strong head-tail instabilities in the presence of the space-charge force. It is a simple expansion of the well-known two particle model for strong head-tail instability and is still ...

The distribution of the maximum of character sums

open access: yes, 2012
We obtain explicit bounds on the moments of character sums, refining estimates of Montgomery and Vaughan. As an application we obtain results on the distribution of the maximal magnitude of character sums normalized by the square root of the modulus ...

Normalizing Batch Normalization for Long-Tailed Recognition

open access: yesIEEE Transactions on Image Processing
In real-world scenarios, the number of training samples across classes usually subjects to a long-tailed distribution. The conventionally trained network may achieve unexpected inferior performance on the rare class compared to the frequent class. Most previous works attempt to rectify the network bias from the data-level or from the classifier-level ...

Dynamic Bivariate Normal Copula

open access: yes, 2015
Normal copula with a correlation coefficient between $-1$ and $1$ is tail independent and so it severely underestimates extreme probabilities. By letting the correlation coefficient in a normal copula depend on the sample size, H\"usler and Reiss (1989 ...

Rank-normalization, folding, and localization: An improved $\widehat{R}$ for assessing convergence of MCMC

open access: yes, 2020
Markov chain Monte Carlo is a key computational tool in Bayesian statistics, but it can be challenging to monitor the convergence of an iterative stochastic algorithm.

Swimming of onboard-powered autonomous robots in viscous fluid filled channels [PDF]

open access: yes, 2011
Microrobots can make a great impact in medical applications such as minimally-invasive surgery, screening and diagnosis of diseases, targeted therapy and drug delivery.
