A novel signal folding and reconstruction scheme for neural recording applications that exploits the characteristics of neural signals is described in this paper. The amplified output is ‘folded’ into a predefined range of voltages by using comparison and reset circuits along with the core amplifier. After this output signal is digitized and transmitted, a reconstruction algorithm can be ap…
Although fathers are increasingly a focus of attention in research, there is a dearth of research on depressive symptoms among fathers, especially young fathers with toddlers. This study used longitudinal data to examine what risk factors, including the age status of fathers (e.g., late adolescence, emerging adulthood, and adulthood), may be associated with depressive symptoms of fathers when …
Abstract. Formation of polymeric spheres in nanometer to sub-micrometer is achieved through a spin-coating process with polyamide (from 4,4-(hexafluoroisopropylidene)dianiline and 4,4-dicarboxydiphenylether) solutions in N,N-dimethylformamide and N,N-dimethylacetamide. The formation of polymeric spheres and their sizes are dependent on the polymer solution concentrations and the rates in …
Abstract. The influence of CO pretreatment on the properties of CuO/CeO2/y-Al2O3 catalysts was investigated using X-ray diffraction (XRD), temperature programmed reduction (TPR), X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (IR). The activities of the treated catalysts were measured in low-temperature CO oxidation reactions (
Summary The Phalaenopsis orchid produces complex flowers that are commercially valuable, which has promoted the study of its flower development. E-class MADS-box genes, SEPALLATA (SEP), combined with B-, C- and D-class MADS-box genes, are involved in various aspects of plant development, such as floral meristem determination, organ identity, fruit maturation, seed formation and plant architec…
This study investigates the impact of labor unions on productivity and technical inefficiency of the U.S. manufacturing sector, using state-level panel data on 48 states from 1983 to 1996. The results indicate that while labor unions reduce firms’ technical progress, they improve firm efficiency in utilizing the existing technology. The findings also suggest that the decline of unionization r…
ABSTRACT This work presents two points with respect to manganese oxide (MnOx) nanomaterials: their controllable synthesis with desired phases and shapes together with their applications as catalysts for oxygen reduction and Al/air batteries. Solid MnOx with crystalline phases of MnOOH, Mn2O3, and MnO2 as well as shapes of the sphere, wire, rod, and particle were prepared through a simple one-…
The cellular and subcellular distributions of trace elements can provide important clues to understanding how the elements are transported and stored in plant cells, but mapping their distributions is a challenging task. The distributions of arsenic, iron, zinc, manganese and copper, as well as physiologically related macro-elements, were mapped in the node, internode and leaf sheath of ri…
