Fast Digital Convolutions using Bit-Shifts

An exact, one-to-one transform is presented that not only allows digital circular convolutions, but is free from multiplications and quantisation errors for transform lengths of arbitrary powers of two. The transform is analogous to the Discrete Fourier Transform, with the canonical harmonics replaced by a set of cyclic integers computed using only bit-shifts and additions modulo a prime number. The prime number may be selected to occupy contemporary word sizes or to be very large for cryptographic or data hiding applications. The transform is an extension of the Rader Transforms via Carmichael's Theorem. These properties allow for exact convolutions that are impervious to numerical overflow and to utilise Fast Fourier Transform algorithms.Comment: 4 pages, 2 figures, submitted to IEEE Signal Processing Letter

IIT-Hyderabad professor Chandra Shekhar Sharma bags award

Professor Chandra Shekhar Sharma from the department of chemical engineering, Indian Institute of Technology, Hyderabad (IIT-H), has won the prestigious Young Scientist Platinum Jubilee Award, instituted by the National Academy of Sciences, India. He has been selected for his work on electrospun nanofibers and nanostructured carbon materials which can be used in environmental protection and healthcare. Professor Chandra Shekhar and his team recently introduced female sanitary napkins, using electrospun nanofibers (biodegradable polymer). Most sanitary napkins use non-biodegradable superabsorbent polymers (SAP) to increase their commercial value. However, they cause health hazards and also environmental problems. The product will soon hit the market after field trials. Furthermore, the team has also received a grant from the department of science and technology under the nano mission programme. The team has also developed an inexpensive way of creating electrodes. The award, started in 2005, is given to scientists in the field of physical, chemical and biological sciences

Preface

Third volume and the second issue (Year 2020) of the scholarly open-access journal Translational Research in Veterinary Science (TRVS), Nicolaus Copernicus University (NCU) publishers is publishing four research papers devoted in the field of veterinary science. In this published issue of TRVS, three manuscripts based on the original research works and a case report. The first paper of Czarnik et al. (2020) published the original research paper based on the trait-associated study conducted on Polish HF cattle to find out the genetic association between bovine CXCL8 gene polymorphism and clinical mastitis and fertility trait; the second paper of Kwiatkowska et al. (2020) published the case report study on cat suffering from gastrointestinal lymphoma to examine the association of toxic encephalopathy with low dose metronidazole therapy; the third paper of Yemets (2020) published the original research paper based on the animal nutrition studies describing the dietary effects of drone larves homogenate on the homeostatic constants and the reproductive capacity of Large White gilts in Ukraine; and lastly the Bak et al. (2020) published the original research paper based on the use of algorithms for multiple DNA sequence alignment across livestock species. During this difficult period of COVID-19 pandemic year, I would like to thank all authors for their contribution to this issue. Thanks are also extended to the editorial board members, manuscripts reviewers, TRVS editorial technical staff working at NCU publisher office (Mirosława Buczyńska, Elżbieta Kossarzecka, Grzegorz Kopcewicz, and Dariusz Żulewski), who supported at every stage of the project. Most importantly, this volume of TRVS is greatly acknowledged the supported of NCU funds from newly elect JM Rector Prof. dr hab. Andrzej Sokala

EMERGING SUBJECTIVITY AND MEANING WITHIN THE LABOR PROCESS OF INDIAN INFORMATION TECHNOLOGY

The limitless possibility of ‘being’, whatever one wants ‘to become’ in the contemporary ‘liquid modern times’ inherently accentuates complexities and ambiguities (Bauman 2000) in the ‘conceptualization of self’. Rather than offering  conduit for fulfillment and stable anchoring for personal identity (Alvesson and Willmott 2002), work in the new economy and corresponding altered employment relations, seem to impose corporate narratives of ‘how one ought to be’. Resulting identities warrant for continuous identity work and thus aggravate perpetual feelings of insecurity and anxiety (Collinson 2003). In absence of traditional anchors of meaning (Sennett 1998) and corresponding unrealized quest  for alternative forms of attachment and belonging (Jackall 1998), subjectivities at work are precarious at the very least. Given the context, the paper interrogates worker subjectivity within the labor process of Indian Information Technology (IT) to delineate meaningful work experiences for employees. The findings explicated from ethnographic field work indicate that despite significant contribution to the Indian economy and catapulting sizeable number of families into higher social strata, the software economy has also resulted in what has been described as ‘deteriorating culture’ by most of the respondents. Unsurprisingly, transactional employment relationships, eroding mutual trust and individual predisposition to self-securing orientation have been found to be prominent characteristics of Indian IT workplaces. It seems that contradictions inherent in the individualization oriented IT labour process in a quasi-collectivistic society such as India erodes the capacity of work in providing salient identity dimensions to its employees. Interestingly, the findings from the field also indicate that work itself has no meaning but it is the instrumentality of work in achieving other life projects, particularly those associated with positive valence in the society which makes work experience as meaningful or meaningless
