Non-Boolean almost perfect nonlinear functions on non-Abelian groups

The purpose of this paper is to present the extended definitions and characterizations of the classical notions of APN and maximum nonlinear Boolean functions to deal with the case of mappings from a finite group K to another one N with the possibility that one or both groups are non-Abelian.Comment: 17 page

Nutrição mineral de bovinos de corte no Pantanal Mato-Grossense. VI. Levantamento de micronutrientes na sub-região de Aquidauana.

Foram analisados Fe, Mn, Cu e Zn em amostras de solo, plantas forrageiras e figado de vacas nelaradas em lactação, coletadas em novembro de 1982, maio e agosto de 1983. Solos e plantas foram coletadas em cinco unidades de pastagens

Deficiência de cálcio em bovinos no Pantanal - Brasil.

Levantamentos sistemáticos de teores de minerais em solos, forrageiras, tecidos de bovinos, com o objetivo de obter dados para a formulação de suplementos minerais específicos para o Pantanal. Os levantamentos consistiram de amostragens realizadas em quatro épocas do ano

Nutrição mineral de bovinos de corte do Pantanal Mato-Grossense: 2. Micronutrientes na Nhecolandia (Parte Central).

Realatam-se resultados de analise de solos, agua, e gramineas nativas, coletadas em 1979, maio/80 e ago/80, e de figado de bovinos, nessas epocas e em fev/80, na sub-regiao de Nhecolandia, do Pantanal Mato-Grossense. Solos e gramineas foram coletados em cino unidades de paisagem : mata, cerrado, caronal, campo limpo e lagoa. Os resultados sugerem a possibilidade de ocorrencia de toxidez de ferro e manganes, durante /apos o periodo de inundacao, e de deficiencias de cobre e zinco, em determinadas epocas, na sub-regiao abrangida

Fabrication and Experimental Evaluation of Simple Tissue-Mimicking Phantoms with Realistic Electrical Properties for Impedance-Based Sensing

Venipuncture is one of the most often performed invasive clinical procedure. Nevertheless, complications still occur. One opportunity to counteract these complications is to indicate the insertion by electrical impedance measurement, which bases on the various electrical properties of different tissues. This paper presents the evaluation and reproducible fabrication of simple tissue-mimicking phantoms for investigation of impedance sensing techniques. Three different tissue-mimicking phantoms, representing blood, fat, and skin, were made on water-based recipes, including agar and gelatin as gelling agents. For evaluation of the electrical properties an electrode probe, made of hypodermic needles, was fabricated and characterized using six sodium chloride (NaCl) solutions of defined concentrations. For characterization of the phantoms, conductances were measured over a frequency range from 20 Hz up to 1 MHz using the self-fabricated electrodes. The calculated conductivities of the tissue-mimicking phantoms showed sufficient agreement with corresponding electrical literature data of native tissue. Tests with a layered tissue structure proved usability for impedance-based venous entry tests. However, the method proposed was not suitable for investigation of relative permittivity, which would be required for full electrical characterization

Highly dynamic robotic leg for non-biomimetic walking robots

Due to a predisposition of DNA to generate symmetric anatomy, there are no tripedal animals in nature. Yet, threelegged walking might be the sweet spot between the energy efficiency of bipeds and the stability of quadrupeds. This paper presents the non-biomimetic leg for the TriPed, a novel three-legged mobile walking robot that aims to study the advantages and disadvantages of three-legged walking. We showcase its new non-biomimetic leg design that allows for fast repositioning by keeping the leg mass close to the body. This is done using physical experiments as well as a simscape simulation. The experiments show that the legs are capable of moving about 3 m/s
