In this paper,we develop a novel global-attentionbased neural network(GANN)for vision language intelligence,specifically,image captioning(language description of a given image).As many previous works,the encoder-decoder framework is adopted in our proposed model,in which the encoder is responsible for encoding the region proposal features and extracting global caption feature based on a specially designed module of predicting the caption objects,and the decoder generates captions by taking the obtained global caption feature along with the encoded visual features as inputs for each attention head of the decoder *** global caption feature is introduced for the purpose of exploring the latent contributions of region proposals for image captioning,and further helping the decoder better focus on the most relevant proposals so as to extract more accurate visual feature in each time step of caption *** GANN is implemented by incorporating the global caption feature into the attention weight calculation phase in the word predication process in each head of the decoder *** our experiments,we qualitatively analyzed the proposed model,and quantitatively evaluated several state-of-the-art schemes with GANN on the MS-COCO *** results demonstrate the effectiveness of the proposed global attention mechanism for image captioning.

Solid oxide electrolysis cell(SOEC) can electrochemically convert CO2 to CO at the gas-solid interface with a high current density and Faradaic efficiency, which has attracted increasing attentions in recent *** efficient catalyst for electrochemical CO2 reduction reaction(CO2 RR) at the cathode is a grand challenge for the research and development of SOEC. Sr2Fe1.5Mo0.5O6-δ(SFM) is one kind of promising cathode materials for SOEC, but suffers from insufficient activity for CO2 RR. Herein, Gd0.2Ce0.8O1.9(GDC)nanoparticles were infiltrated onto the SFM surface to construct a composite GDC-SFM cathode and improve the CO2 RR performance in SOEC. The current density over the GDC infiltrated SFM cathode with a GDC loading of 12.8 wt% reaches 0.446 A cm-2 at 1.6 V and 800 °C, which is much higher than that over the SFM cathode(0.283 A cm-2). Temperature-programmed desorption of CO2 measurements suggest that the infiltration of GDC nanoparticles significantly increases the density of surface active sites and three phase boundaries(TPBs), which are beneficial for CO2 adsorption and subsequent conversion. Electrochemical impedance spectroscopy results indicate that the polarization resistance of 12.8 wt% GDCSFM cathode was obviously decreased from 0.46 to 0.30 cm^2 after the infiltration of GDC nanoparticles.

Photonic crystal fibers are usually divided into two different types of fibers： solid-core photonic crystal fibers （PCFs） and air-core photonic bandgaps fibers （PBFs）. We presented the fabrication methods and applications of long period fiber gratings （LPFGs） written in these two types of photonic crystal fibers by use of a CO2 laser. A stain sensor with a high sensitivity was demonstrated by use of an LPFG written in solid-core PCFs. An in-fiber polarizer based on an LPFG was fabricated by use of a focused CO2 laser beam to notch periodically on a PCF. A novel LPFG was written in an air-core PBF by use of a CO2 laser to collapse periodically air holes in the fiber cladding.

Hybrid adsorbents for COcapture were prepared by coassembling laponite（LP） nanosheets and 1-nbutyl-3-methylimidazolium chloride（BMIMCl）. The prepared BMIMCl/LP layered hybrids were systematically characterized. The interlayer distance of the BMIMCl/LP layered hybrids expanded with an increasing concentration of BMIMCl, indicating that cumulative BMIMCl was intercalated into the LP layers. The efficiency of BMIMCl toward COcapture was significantly enhanced after it was immobilized within LP layers.
