The electronic transport properties of the delafossite oxides [Formula: see text] are usually understood in terms of two well-separated entities, namely the triangular [Formula: see text] and ([Formula: see text] layers. Here, we review several cases among this extensive family of materials where the transport depends on the interlayer coupling and displays unconventional properties. We review ...

To figure out whether spermidine (Spd) can alleviate oxidative damage on rice (Oryza sativa L.) caused by submergence stress, Ningjing 3 was used in this study. The results showed that, spraying Spd on rice leaves at a concentration of 0.5 mM promoted the growth recovery of rice after drainage, such as green leaves, tillers, and aboveground dry mass. According to physiological analysis, Spd acc...

In the present study, the possibility of concentrating tungsten-copper vein ore in South Chah-Palang was examined using gravity separators including Jig Machine (-2360+600 μm), shaking table (-600+120 μm), and multi-gravity separator (MGS) (-120 μm). The representative sample contains 1.5% WO3 and 5.95% CuO. The main tungsten minerals were ferberite and wolframite and their appropriate liberati...

In an iodometric titration method for iodine (or chlorine) analysis, the percent recovery of iodine (or chlorine) decreases in the low concentration region and at the relatively higher temperature range. We have shown that the percent recovery vs. concentration curve can be expressed by a simple empirical formula. The empirical formula contains parameters that depend on temperature and those pa...

In this paper we analyze the complexity of placing recovery points where the computation is modeled as a reverse binary tree task model. The objective is to minimize the expected computation time of a program in the presence of faults. The method can be extended to an arbitrary reverse tree model. For uniprocessor systems, we propose an optimal placement algorithm. For multiprocessor systems, w...

Hypoglycemic injury in the mature brain is mediated by excitotoxicity, which is worsened by disordered cellular energy metabolism. The role of excitotoxicity in relation to brain energy metabolism during hypoglycemia has not been studied in the immature brain. Brain oxygen consumption ([Formula: see text]) increases during hypoglycemia in piglets, whereas [Formula: see text] decreases in adult ...

This paper focuses on the sufficient condition of block sparse recovery with the [Formula: see text]-minimization. We show that if the measurement matrix satisfies the block restricted isometry property with [Formula: see text], then every block s-sparse signal can be exactly recovered via the [Formula: see text]-minimization approach in the noiseless case and is stably recovered in the noisy m...

Donoho and Stark have shown that a precise deterministic recovery of missing information contained in a time interval shorter than the time-frequency uncertainty limit is possible. We analyze this signal recovery mechanism from a physics point of view and show that the well-known Shannon-Nyquist sampling theorem, which is fundamental in signal processing, also uses essentially the same mechanis...
