Futuristic person re-identification over internet of biometrics things (IoBT): Technical potential versus practical reality
No full textThis article presents an overview of how person re-identification can be achieved over the Internet of Biometric Things (IoBT) architecture by enabling technologies and protocols for multimodal biometric authentication leveraging futuristic cues. The Internet of Things (IoT), as a new era of technology, extends the power of the internet to a whole range of devices, thus reshaping our daily lives in the best possible way. IoT-enabled intelligent surveillance devices are the most indispensable part of public safety and security in smart cities. These IoT devices generate a vast amount of surveillance traffic that is practically impossible for humans to continuously monitor and/or analyze. Person re-identification (PRId), which aims to track and recognize a person in a multi-camera scene is an important feature of visual surveillance systems in IoT infrastructures and can utilize the aforementioned traffic. This is where the concept of IoBT, which is a cloud-centric biometric authentication architecture composed of these IoT-enabled devices for the PRId system, comes into play. This article conceptualizes an overview of interpreting various futuristic cues on the IoT platform for achieving PRId. We highlight some opportunities and key challenges of implementing this futuristic PRId system on IoBT. The article is a proof of concept of the technical potential of such implementation in the near future

A Multi-Language Comparison of Influences on Author Verification using Character N-Grams
No full textWe create a new multi-language corpus for author verification based on Wikipedia talkpages, and evaluate the influence that differences in topic and time have on character n-gram author profiles. Topic alignment between two texts is found to increase author verification precision, and an authors writing style is found to change over time, but not more significantly after 3 years than after 1 year.Information ArchitectureWISElectrical Engineering, Mathematics and Computer Scienc
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
A Near-Optimal Polynomial Distance Lemma over Boolean Slices
No full textThe celebrated Ore-DeMillo-Lipton-Schwartz-Zippel (ODLSZ) lemma asserts that n-variate non-zero polynomial functions of degree d over a field , are non-zero over any "grid" (points of the form Sⁿ for finite subset S ⊆ ) with probability at least max{|S|^{-d/(|S|-1)},1-d/|S|} over the choice of random point from the grid. In particular, over the Boolean cube (S = {0,1} ⊆ ), the lemma asserts non-zero polynomials are non-zero with probability at least 2^{-d}. In this work we extend the ODLSZ lemma optimally (up to lower-order terms) to "Boolean slices" i.e., points of Hamming weight exactly k. We show that non-zero polynomials on the slice are non-zero with probability (t/n)^{d}(1 - o_{n}(1)) where t = min{k,n-k} for every d ≤ k ≤ (n-d). As with the ODLSZ lemma, our results extend to polynomials over Abelian groups. This bound is tight upto the error term as evidenced by multilinear monomials of degree d, and it is also the case that some corrective term is necessary. A particularly interesting case is the "balanced slice" (k = n/2) where our lemma asserts that non-zero polynomials are non-zero with roughly the same probability on the slice as on the whole cube.
The behaviour of low-degree polynomials over Boolean slices has received much attention in recent years. However, the problem of proving a tight version of the ODLSZ lemma does not seem to have been considered before, except for a recent work of Amireddy, Behera, Paraashar, Srinivasan and Sudan (SODA 2025), who established a sub-optimal bound of approximately ((k/n)⋅ (1-(k/n)))^d using a proof similar to that of the standard ODLSZ lemma.
While the statement of our result mimics that of the ODLSZ lemma, our proof is significantly more intricate and involves spectral reasoning which is employed to show that a natural way of embedding a copy of the Boolean cube inside a balanced Boolean slice is a good sampler
Synthesis and characterization of linear dendritic homo and copolymers acrylated behera amine
No full text<div><p>A co-polymerizable dendron of first generation synthesized from behera amine was homopolymerized and copolymerized with commercial monomers such as styrene, methyl methacrylate, and N-vinyl pyrrolidone. Characterization of the co-polymers was performed and it was found with the help of FT-IR and proton and carbon NMR that copolymerizable dendron, ACTES (<b>AC</b>rylated <b>T</b>ri<b>ES</b>ter, first-generation dendron of acrylated behera amine) was incorporated in the co-polymer chains. Besides, the reactivity ratio pairs of the ACTES monomer with both styrene and n-vinyl pyrrolidone were determined. The reactivity ratio pair for ACTES and MMA could not be determined by neither gravimetrically nor with NMR. After experiments and calculations, the reactivity ratio pair for styrene and ACTES was found to be <i>r</i><sub>st</sub> = 0.27 and <i>r</i><sub>ac</sub> = 0.44 and for NVP and ACTES <i>r</i><sub>nv<i>p</i></sub> = 0.36 and <i>r</i><sub>ac</sub> = 1.01. By utilization of the reactivity ratio of ACTES, “<i>Q</i>” and “<i>e</i>” values were determined in order to be able to draw some conclusions about the reactivity behavior during copolymerizations. “<i>Q</i>” = 1.152 and “<i>e</i>” = 0.66 were found with respect to styrene as reference. These values indicates the steric effect of ACTES was more dominant in copolymerizations.</p></div
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
