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
Mechanically processed Sardinian wool promotes C-C bond synthesis under solvent-free conditions
No full textThe tangible environmental concerns of the last few decades are prompting science to a new sustainable paradigm for chemical reactions and a circular economy. In the present manuscript, complying with this dichotomy, Sardinian wool is presented as a promising material for organic synthesis. Aldol and nitro-aldol additions, and Knoevenagel reactions were demonstrated with high efficiency under wool-promoted and solvent-free conditions, paving the way to novel approaches for converting wool biomass waste into value-added products for C-C bond formation

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

Growth and dynamic magnetization study of Co2MnAl full Heusler alloy thin films
No full textStructural and dynamic magnetization properties of Co2MnAl (CMA) full Heusler alloy thin films grown on Si (100) substrates at different substrate temperatures (T-s) room temperature (RT), 200 degrees C, 300 degrees C, 400 degrees C and 500 degrees C are investigated. X-ray diffraction patterns revealed the formation of B2 ordered phase. Ferromagnetic Resonance (FMR) technique have been used to investigate the dynamic magnetization response. From the observed frequency dependence of the resonance field (H-r) and line width (Delta H), the effective saturation magnetization (4 pi M-eff) and damping constant () have been evaluated. The lowest damping constant was found to be 0.007 +/- 0.002 for the film grown at T-s=200 degrees C which is comparable to the reported value.</p
Effect of post-annealing on the magnetic properties of sputtered Mn56Al44 thin films
No full textMa(56)Al(44) (MnAl) thin films of constant thickness (similar to 30nm) were grown on naturally oxidized Si substrates using DC-magnetron sputtering. Effect of deposition parameters such as sputtering power, substrate temperature (T-s), and post-annealing temperature have been systematically invstigated. X-ray diffraction patterns revealed the presence of mixed phases, namely the tau- and beta-MnAl. The highest saturation magnetization (M.$) was found to be 65emu/cc using PPMSVSM in film grown at T-s =500 degrees C. The magnetic ordering was found to get significantly improved by performing post annealing of these as-grwon at 400 degrees C for 1 hr in the presence of out-of-plane magnetic field of similar to 15000e in vacuum. In particular, at room temperature (RT), the Ms got enhanced after magnetic annealing from 65mm/cc to 500 emu/cc in MnAl films grown at T-s=500 degrees C. This sample exhibited a magneto-resistance of similar to 1.5% at RT. The tuning of the structural and magnetic properties of MnAl binary alloy thin films as established here by varying the growth parameters is critical with regards to the prospective applications of MnAI, a metastable ferromagnetic system which possesses the highest perpendicular magnetic anisotropy at RT till date.</p
