23 The frequency resolution of auditory neurons throughout the ascending auditory pathway 24 is an important parameter for understanding how sounds are processed. It has been shown in 25 previous animal studies that the frequency tuning widths are about 1/5 octave wide in auditory 26 nerve fibers and much wider in auditory cortex neurons (Pickles, 1979; McLaughlin et al., 2008; 27 see Table 1)....

Tuning a microwave filter is challenging problem due to its complexity. Extracting coupling matrix from given S-parameters essential for ?lter tuning and design. In this paper, deep-learning-based neural network namely, convolutional (CNN) proposed extract of filters. The training the CNN based on circuit model. order exhibit robustness new technique, it applied 5- 8-pole filters compared with ...

In order to increase the accuracy of on-line liquid density measurements, a sensor equipped with a tuning fork as the resonant sensitive component is designed in this paper. It is a quasi-digital sensor with simple structure and high precision. The sensor is based on resonance theory and composed of a sensitive unit and a closed-loop control unit, where the sensitive unit consists of the actuat...

Neonatal brain injury triggers compensatory processes that can be adaptive or detrimental, but little is known about the mechanisms of compensation or how they might affect the response properties of neurons within the injured region. We have studied this issue in a rodent model. Partial ablation of the hamster superior colliculus (SC) at birth results in a compressed but complete visual field ...

Local circuit neurons in the dorsolateral prefrontal cortex (dPFC) of monkeys have been implicated in the cellular basis of working memory. To further elucidate the role of inhibition in spatial tuning, we iontophoresed bicuculline methiodide (BMI) onto functionally characterized neurons in the dPFC of monkeys performing an oculomotor delayed response task. This GABA(A) blockade revealed that b...

Synthetic biologists aim to construct novel genetic circuits with useful applications through rational design and forward engineering. Given the complexity of signal processing that occurs in natural biological systems, engineered microbes have the potential to perform a wide range of desirable tasks that require sophisticated computation and control. Realising this goal will require accurate p...

An evolutionary algorithm is used to evolve a digital circuit which computes a simple hash function mapping a 16-bit address space into an 8-bit one. The target technology is FPGA, where the search space of the algorithm is made of the combinational functions computed by cells and of the interconnections among cells. The evolutionary technique has been applied to five different interconnection ...

This article describes a numerical procedure designed to tune the parameters of periodically driven dynamical systems to a state in which they exhibit rich dynamical behavior. This is achieved by maximizing the diversity of subharmonic solutions available to the system within a range of the parameters that define the driving. The procedure is applied to a problem of interest in computational ne...
