p-Aminohippuric acid (PAH) transport by basolateral membrane (BLM) vesicles isolated from rat renal cortex was stimulated very little by a Na+ gradient (out greater than in). However, when micromolar concentrations of glutaric acid or alpha-ketoglutaric acid were added in the presence of a out greater than in Na+ gradient, PAH uptake was accelerated greater than 20-fold and an overshoot of greater than fivefold was produced. Other anions, e.g., fumarate, stimulated PAH uptake very modestly under these conditions (approximately 2-fold), and that stimulation was totally prevented by short circuiting, i.e., with K+ (in = out) and valinomycin. Glutarate-stimulated uptake was inhibited by 4-acetamido-4'-isothiocyanostilbene-2,2'-disulfonic acid (SITS) and probenecid and was slightly stimulated by the imposition of an inside-negative membrane potential. Furthermore, even in the absence of a Na+ gradient, glutarate-loaded vesicles exhibited a marked acceleration of PAH uptake (5-fold) and a modest overshoot (2.5-fold). These results suggest an indirect coupling of BLM PAH uptake to the Na+ gradient by a cyclic accumulation (Na+-dependent) of glutarate followed by its efflux from the vesicle in exchange for PAH. This coupled system was absent in apical membranes. Thus net secretory transport of PAH may entail Na+-dependent, glutarate-driven PAH uptake at the BLM, followed by the exit of PAH into the lumen down its electrochemical gradient, probably in exchange for other anions, e.g., Cl-, HCO3-, or OH-.

The recent discovery of the interfacial superconductivity (SC) of the Bi2Te3/Fe1+yTe heterostructure has attracted extensive studies due to its potential as a novel platform for trapping and controlling Majorana fermions. Here we present studies of another topological insulator (TI)/Fe1+yTe heterostructure, Sb2Te3/Fe1+yTe, which also has an interfacial 2-dimensional SC. The results of transport measurements support that reduction of the excess Fe concentration of the Fe1+yTe layer not only increases the fluctuation of its antiferromagnetic (AFM) order but also enhances the quality of the SC of this heterostructure system. On the other hand, the interfacial SC of this heterostructure was found to have a wider-ranging TI-layer thickness dependence than that of the Bi2Te3/Fe1+yTe heterostructure, which is believed to be attributed to the much higher bulk conductivity of Sb2Te3that enhances indirect coupling between its top and bottom topological surface states (TSSs). Our results provide evidence of the interplay among the AFM order, itinerant carries from the TSSs, and the induced interfacial SC of the TI/Fe1+yTe heterostructure system.

Determining the coupling between systems remains a topic of active research in the field of complex science. Identifying the proper causal influences in time series can already be very challenging in the trivariate case, particularly when the interactions are non-linear. In this paper, the coupling between three Lorenz systems is investigated with the help of specifically designed artificial neural networks, called time delay neural networks (TDNNs). TDNNs can learn from their previous inputs and are therefore well suited to extract the causal relationship between time series. The performances of the TDNNs tested have always been very positive, showing an excellent capability to identify the correct causal relationships in absence of significant noise. The first tests on the time localization of the mutual influences and the effects of Gaussian noise have also provided very encouraging results. Even if further assessments are necessary, the networks of the proposed architecture have the potential to be a good complement to the other techniques available in the market for the investigation of mutual influences between time series.

We have measured the angular dependence of the line width in thallium and related it to the second moment to estimate the pseudodipolar and pseudoexchange contributions for the first two shells of neighbors. These values are very different, despite the fact that both shells have nearly the same radius, and this establishes experimentally for the first time an orientation dependence of the indirect coupling constants.

In this paper, optimization of a microstrip patch antenna is presented. The optimization uses a genetic algorithm in the IE3DTM Simulator. The optimization is done in several steps, first by changing the position of parasitic patches on the top layer, second by placing a feeding patch at the middle layer of geometry, and third by indirect coupling between the top and middle layer patches. Overall, we have performed many possible iterations and found appropriate geometry. From this appropriate geometry we have achieved maximum directional gain (6.2–8.8 dBi) over a 6 GHz bandwidth slot, 38% impedance bandwidth of the X-band and 14.8% impedance bandwidth of the Ku-band. The broadband frequency of operation is demonstrated by single geometry. The geometry of a single probe fed rectangular microstrip antenna incorporating a slot, gap coupled with a parasitic and an active patch on geometry, has been studied. We have investigated the height between active and parasitic patches as 0.0525λ and the height between parasitic patches itself as 0.0525λ. We have investigated the enhancement in maximum directional gain by stacking geometry with one active patch and two parasitic patches of different dimensions. This optimized antenna is used for X-band and Ku-band applications. The hardware validation and simulation results are matched to the proposed design.
