A proof of a trigonometric inequality. A glimpse inside the mathematical kitchen
(2011-09)
We prove the inequality ∞ ∑ k=1(−1) k+1 rk cos kφ k+2 < ∞ ∑ k=1 (−1) k+1 rk k+2 for 0 < r 1 and 0 < φ < π . For the case r = 1 we give two proofs. The first one is by means of a general numerical technique (Maximal Slope ...

Scatter search-based identification of local patterns with positive and negative correlations in gene expression data
(Elsevier, 2015)
This paper presents a scatter search approach based on linear correlations among genes to find biclusters, which include both shifting and scaling patterns and negatively correlated patterns contrarily to most ...

A 32 x 32 Pixel Convolution Processor Chip for Address Event Vision Sensors With 155 ns Event Latency and 20 Meps Throughput
(IEEE Computer Society, 2011)
This paper describes a convolution chip for event-driven vision sensing and processing systems. As opposed to conventional frame-constraint vision systems, in event-driven vision there is no need for frames. In frame-free ...

Electrokinetic modelling of cone-jet electrosprays
(Cambridge University Express, 2023)
The physics of electrospray has been subject to an intense debate for three decades regarding the ultimate electrokinetics that determines the electric current and the size of the emitted droplets in the steady Taylor ...

Supervised classification and mathematical optimization
(Elsevier, 2013-01)
Data Mining techniques often ask for the resolution of optimization problems. Supervised Classification, and, in particular, Support Vector Machines, can be seen as a paradigmatic instance. In this paper, some links between ...

The Functional Relationship between NADPH Thioredoxin Reductase C, 2-Cys Peroxiredoxins, and m-Type Thioredoxins in the Regulation of Calvin–Benson Cycle and Malate-Valve Enzymes in Arabidopsis
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-05-03)
The concerted regulation of chloroplast biosynthetic pathways and NADPH extrusion via malate valve depends on f and m thioredoxins (Trxs). The finding that decreased levels of the thiol-peroxidase 2-Cys peroxiredoxin (Prx) ...

Conformance checking and diagnosis for declarative business process models in data-aware scenarios
(Elsevier, 2014)
A business process (BP) consists of a set of activities which are performed in coordination in an organizational and technical environment and which jointly realize a business goal. In such context, BP management (BPM) ...

Balanced Microwave Transmission Lines, Circuits, and Sensors
(IEEE (Institute of Electrical and Electronics Engineers), 2023)
This paper provides an overview of balanced (or differential-mode) structures operating at microwaves, including common-mode suppression filters, balanced filters and circuits with intrinsic common-mode suppression, and ...

Regulation of Dab2 expression in intestinal and renal epithelia by development
(Wiley-Blackwell, 2011)
Disabled-2 (Dab2) is an intracellular adaptor protein proposed to function in endocytosis. Here, we investigate the intestinal and renal Dab2 expression versus maturation. Dab2 mRNA levels measured by RT-PCR are greater ...
