Managers have discretion as to whether to quantify their earnings guidance and supplementary disclosures. Using an experimental approach, we provide and test theory that when guidance is qualitative, quantifying supplementary attributions leads to more favorable investment judgments; for...

Compliant mechanisms with corrugated flexure (CF) units have been attracting increasing attention due to their large range of motion. However, most research has considered in-plane compliance, whereas the out-of-plane performance, which affects the load-carrying ability, has seldom been studied....

High- β p scenario addresses needs for an attractive tokamak fusion reactor design, where β p is the normalized plasma poloidal beta. The high-performance region is realized by the integration of internal and external transport barriers which are dubbed as ITBs and ETBs with the high-power NBI...

The amidoxime-modified ultrathin polyethylene fibrous membrane (called as AFM) is prepared by a two-step graft polymerization method. The nano-sized particle structures are constructed on the AFM adsorbents surface after grafting. The adsorption behaviors of AFM adsorbent are studied by...

To promote the heat transfer capacity of the condenser end in the heat pipe heat exchanger, the experimental and numerical investigation have been carried out to study the heat transfer and fluid flow characteristics for three densely longitudinal fins enhanced annular heat exchanger (AHE)...

Truss-type lattice structures show great application potential in turbine blade cooling. Using the transient liquid crystals (TLC) experimental method and numerical simulation, this study investigated the heat transfer and flow characteristics of Kagome and BCC (Body Centered Cubic) lattice...

Fractional vegetation cover (FVC) plays an important role in the study of vegetation growth state, and the key issue is accurately segmenting and extracting green vegetation from the background. However, the shadows generated by natural lights produce extreme illuminance differences in images,...

Currently, the implantation and health treatment of electronic devices based on adhesion and flexible substrates are widely studied. However, these adhesive layers are usually non-conductive, and how to achieve stable electrical conductivity on flexible substrates remains challenging. Here, a...

Exploitation of oxygen evolution reaction (OER) and urea oxidation reaction (UOR) catalysts with high activity and stability at large current density is a major challenge for energy-saving H2 production in water electrolysis. Herein, we successfully use the NiFe2O4 nanosheet to activate the...
