Metallic actuators increasingly exhibit superiority over conventional (such as piezoelectric ceramics) via low energy consumption and large strain amplitude. Large amplitude high density (or work density) are required for an actuator with excellent comprehensive performance. Herein, we fabricated bulk nanoporous Pd (np-Pd) a dense structure by two-step potentiostatic dealloying of as-annealed N...

This study focuses on the effects of vegetation patch density, bed condition, and incoming sediment flow structure morphology within around a patch. The variation in upstream adjustment velocity is not well defined for low-density patches but decreases with increasing density high-density patches. length region greater vegetation. Incoming causes reduction both steady wake at low density. recov...

The Fourier transform of a dataset apodised with a window function is known as the Gabor transform. In this paper we extend the Gabor transform formalism to the sphere with the intention of applying it to CMB data analysis. The Gabor coefficients on the sphere known as the pseudo power spectrum is studied for windows of different size. By assuming that the pseudo power spectrum coefficients are...

We examined the prognostic value of programmed cell death-1 (PD-1) and its ligand (PD-L1) together with CD8+ tumor-infiltrating lymphocytes (TILs) and FOXP3+ Tregs in resectable pancreatic ductal adenocarcinoma (PDAC) samples treated with adjuvant chemotherapy. Whole-mount FFPE tissue sections from 145 pancreatectomies were immunohistochemically stained for PD-1, PD-L1, CD8 and FOXP3. Their exp...

A broadband sonar system and digital camera with strobe lights were mounted on a vertically profiling frame with a depth sensor. The echo strengths and densities of animals within individual mesopelagic boundary community patches were investigated as a function of depth. Time and distance from shore were also investigated. Simultaneous surface echosounder surveys permitted comparison of density...

BACKGROUND Previous studies have shown a lower incidence of stroke in Parkinson's disease (PD) patients. The role of the lipids and lipoproteins as risk factors for stroke is uncertain in the lower prevalence of stroke in PD patients. OBJECTIVES To explore the lipids and lipoproteins serum levels in PD patients. METHODS A retrospective study was performed on 110 PD patients (PD group), 130 ...

Noble transition metals, like palladium (Pd) and platinum (Pt), have been well-known for their excellent catalytic and electrochemical properties. However, they have been considered non-active for surface enhanced Raman spectroscopy (SERS). In this work, we explore the scattering contributions of Pd and Pt for the detection of organic molecules. The Pd and Pt nanostructures were synthesized on ...

It is estimated that over one billion milkweed stems need to be restored sustain the eastern North American migratory population of monarch butterflies; where and in what context should placed on landscape key addressing habitat deficits. We assessed how amount appropriate surrounding a particular patch affects presence reproduction. To ensure restoration efforts are targeted towards areas maxi...

The adsorption properties of thin silica films on Mo(112) have been tailored by embedding single Pd atoms into the nanopores of the oxide material. The embedded Pd is able to anchor metal adatoms that would not bind to the inert silica surface otherwise. Several adsorption structures, e.g., Pd-Pd, Ag-Pd, and Au-Pd complexes, have been prepared in this way and analyzed with the STM and density f...

BACKGROUND Immune checkpoint inhibitors targeting programmed cell death 1 (PD1) or its ligand (PD-L1) showed activity in several cancer types. METHODS We performed immunohistochemistry for CD3, CD8, CD20, HLA-DR, phosphatase and tensin homolog (PTEN), PD-1, and PD-L1 and pyrosequencing for assessment of the O6-methylguanine-methyltransferase (MGMT) promoter methylation status in 135 glioblastom...
