El propósito de este artículo es dar cuenta de la experiencia de los circuitos de producción de alimentos frescos en pequeña escala que se relacionan con la economía social y con la promoción estatal de la agricult...

Semiconductor nanowires have been used in a variety of passive and active optoelectronic devices including waveguides, photodetectors, solar cells, light-emitting diodes (LEDs), lasers, sensors, and optical ant...

Recent years have enjoyed a strong interest in exploring properties and applications of random quantum circuits. In this work, we explore the ensemble of t-doped Clifford circuits on n qubits, consisting of Clifford circ...

Conventional antennas, which are widely employed to transmit radio and TV signals, can be used at optical frequencies as long as they are shrunk to nanometer-size dimensions. Optical nanoantennas made of metallic or high...

Este texto apresenta algumas hipóteses e idéias sobre o comércio de abastecimento da cidade de São Paulo, entre os anos 1765-1822, através de dados quantitativos e qualitativos levantados em dois conjuntos documenta...

Semiconductor integrated circuits use ultra-flat substrates called wafers, in which minute irregularities are eliminated to the utmost limit. To produce such a flat substrate, a polishing technique called chemical mechan...

Post-traumatic stress disorder (PTSD) is a severe neuropsychiatric disorder characterised by re-experiencing, avoidance and hyperarousal. Memory abnormalities manifested as intrusive thoughts and prolonged distressful em...

Luminescent nanothermometry uses the light emission from nanostructures for temperature measuring. Non-contact temperature readout opens new possibilities of tracking thermal flows at the sub-micrometer spatial scale, th...

Abstract Thalamocortical circuits regulate information flow between sensory inputs and higher-order processing, and their disruption is increasingly implicated in psychotic disorders. However, scalable biomarkers of this...

Abstract Here, we review mathematical models of epigenetic memory, focusing on chromatin modifications as key mechanisms to achieve long-term maintenance of epigenetic states. After reviewing the main stochastic modeling...

Bound states in the continuum (BICs) have attracted much attention in the field of nanophotonics owing to their ability to trap photons without loss. Recently, a low-refractive-index (RI) waveguide loaded on a high-RI sl...

We demonstrate a metamaterial platform for electrically driven broadband light emission induced by electron tunneling. Both the Fabry-Perot and waveguided modes of the metamaterial slab as well the plasmonic mode of the ...

The application of the graphical Hopf theorem (GHT) as a tool for detecting invariant cycles in maps is presented. The invariant cycle emerging from the bifurcation is approximated using an analogous version of the GHT f...

We present partial results of a research project in which we use boolean circuits as a parallel computation model for the expression of queries to relational databases. For that purpose, we use the well-known equivalence...

Information about the basal ganglia has accumulated at a prodigious pace over the past decade, necessitating major revisions in our concepts of the structural and functional organization of these nuclei. From earlier dat...

Standard hardware, dedicated microcontroller or application specific circuits can implement fuzzy logic or neural network controllers. This paper presents efficient architecture approaches to develop controllers using sp...

In this paper, we discuss consensus problems for networks of dynamic agents with fixed and switching topologies. We analyze three cases: 1) directed networks with fixed topology; 2) directed networks with switching topol...

A new two-terminal circuit element-called the memristorcharacterized by a relationship between the charge q(t)\equiv \int_{-\infty}^{t} i(\tau) d \tau and the flux-linkage \varphi(t)\equiv \int_{- \infty}^{t} v(\tau) d \...

Over the last 20 years, Bulk Current Injection (BCI) testing has become increasingly critical for assessing the electromagnetic compatibility (EMC) of integrated circuits (ICs) in automotive applications. This PhD thesis...

Information processing in the cerebral cortex involves interactions among distributed areas. Anatomical connectivity suggests that certain areas form local hierarchical relations such as within the visual system. Other c...
