Bottom-water hypoxia (≤2 mg l–1 dissolved oxygen [DO]) greatly modifies the benthic habitat of estuaries, depending upon spatial extent, duration, and frequency. Bottom-water hypoxia often develops under conditions of density stratification, which inhibits vertical mixing, and warm temperatures, which enhance biological oxygen demand. Long-term, mid-channel data from the Neuse River Estuary in ...

The performance of solution cross-polarization using trains of shaped pulses on two channels is investigated by computer simulation and experiment. It is determined that a Waltz modulation pattern of Gaussian pulses of individual flip angles of 225°, issued to two coupled spins simulatneously, yields excellent coherence transfer with good phasing behavior. Simulations and experimental verificat...

Visuomotor priming occurs when our actions are influenced by observing a compatible or incompatible action. Here we ask whether visuomotor priming is specific to human, biological actions or generalises to non-biological movements, such as abstract shapes or robots. Reviewing the evidence indicates that priming occurs for both types of stimuli and emphasises the contributions of both bottom-up ...

A transmitarray adopting dual-layer polarisation rotating (PR) elements is proposed. The element comprises a pair of perpendicularly placed C-shaped slots etched on the two sides single-layer substrate and orthogonally rotates transmission wave with regard to incidence. By adjusting slot's dimension as well mirroring bottom layer element, 360° phase shift high magnitude achieved. Based proposed...

We present a polarization-insensitive plasmonic photoconductive terahertz emitter that uses a two-dimensional array of nanoscale cross-shaped apertures as the plasmonic contact electrodes. The geometry of the cross-shaped apertures is set to maximize optical pump absorption in close proximity to the contact electrodes. The two-dimensional symmetry of the cross-shaped apertures offers a polariza...

Abstract This study investigates the empirical validity of the variability hypothesis in Turkey for the period of February 2005-November 2015, by using cross-sectional relative price data and by focusing on the assumptions of linearity and stability. The linearity assumption between the two variables is ensured by estimating quadratic regression equation. The assumption of stability is secur...

A probe-fed circularly polarized stacked patch antenna is presented and simulated by using Commercial Ansoft High Frequency Structure Simulator. The design consists of two patches and two substrates. The bottom patch is square-shaped where as the top patch is of triangularshaped. T-shaped slots parallel to the edges of the patches are inserted so that bandwidth can be improved. Enhancement of t...

The combination of high-resolution tantalum/tungsten (Ta/W) shadowing at very low specimen temperature (-250 degrees C) under ultrahigh vacuum (less than 2 x 10(-9) mbar) with circular harmonic image averaging revealed details on the surface structure of mitochondrial creatine kinase (Mi-CK) molecules with a resolution less than 2.5 nm. Mi-CK octamers exhibit a cross-like surface depression div...
