Geographical information systems(GIS)are essential tools for mineral prospectivity modeling(MPM).Three-dimensional(3D)MPM is able to learn the association between geological evidence and mineralization in shallow zones and thereby build a prospectivity model for deep zones,making it a desirable technique to target deep-seated orebodies.However,existing 3D MPM methods directly generalize the model learned in shallow zones to the deep zones without attention to model transferability caused by the different metallogenic mechanisms between the two zones.In this study,we aim to robustly transfer the prospectivity model learned from shallow zones to deep zones.We cast the 3D MPM as a domain adaptation problem,which is an important realm of transfer learning.Because the metallogenic mechanism can be closely associated with spatial locations,we specifically focus on domain adaption concerning the spatial locations that are ignored by conventional domain adaptation methods.To measure the spatial-associated domain discrepancy,we propose a novel spatial-associated maximum mean discrepancy(SAMMD),which compares the joint distributions of features and spatial locations across domains.Based on the SAMMD criterion,a deep neural network,referred to as the spatial-associated domain adaptation network,is devised to learn cross-domain but mineralization-indicative features for building prospectivity model that is transferable to deep zones.A case study of the world-class Sanshandao gold deposit,in eastern China,was carried out to validate the effectiveness of the proposed methods.The results show that compared with other leading MPM methods and other domain adaption variants,the proposed method has superior prediction accuracy and targeting efficiency,demonstrating the effectiveness and robustness of the proposed method in targeting deep-seated orebodies in areas with different metallogenic mechanisms and no labeled data.

Long-range olefin isomerization could lead to the remote functionalization of hydrocarbon chains,which is advantageous with regards to atom-,step-,and redox economy.However,present methodologies for long-range olefin isomerization are mainly focused on heteroatom directed remote olefin migration;studies using aryl groups as the directing group are limited.The limited examples either utilize aryl olefins with special substituted groups on a benzene ring,or use elaborately optimized ligands or co-catalysts to accelerate the isomerization.A more simple catalytic system for general aryl olefins,without the need for special ligands or co-catalysts,was to be developed.Herein,we report a Pd-catalyzed long-range olefin isomerization(up to 15 units)for general aryl olefins via a 1,2-hydrogen shift mechanism.This methodology provides a simple pathway to long-range olefin isomerization without the participation of special ligands or co-catalysts.

Efficient motion detection is essential for the Internet of Things. However, it suffers from overloading redundant static background information. Inspired by the human visual system, which is efficient in motion detection, we propose a silicon-based retinomorphic photodetector with a simple metal/insulator/semiconductor(MIS)structure, which is compatible with the complementary metal-oxide-semiconductor(CMOS)industry. In contrast to conventional photodetectors that generate a sustained photocurrent, our retinomorphic photodetector is sensitive only to the change in light intensity and therefore filters the redundant static background. In addition, it shows logarithmic dependence on the light intensity, which simplifies the contrast ratio measurement. Based on our moving object recognition experiment, after filtering background information, the information to be analyzed is reduced to 27.3%, thereby improving the image recognition efficiency in the subsequent processing tasks. This innovative and industry-compatible retinomorphic photodetector will facilitate the construction of future efficient motion detection systems.

tRNA-derived small RNAs(tsRNAs)are novel non-coding RNAs that are involved in the occurrence and progression of diverse diseases.However,their exact presence and function in hepatocellular carcinoma(HCC)remain unclear.Here,differentially expressed tsRNAs in HCC were profiled.A novel tsRNA,tRNAGln-TTG derived 5′-tiRNA-Gln,is significantly downregulated,and its expression level is correlated with progression in patients.In HCC cells,5′-tiRNA-Gln overexpression impaired the proliferation,migration,and invasion in vitro and in vivo,while 5′-tiRNA-Gln knockdown yielded opposite results.5′-tiRNA-Gln exerted its function by binding eukaryotic initiation factor 4A-I(EIF4A1),which unwinds complex RNA secondary structures during translation initiation,causing the partial inhibition of translation.The suppressed downregulated proteins include ARAF,MEK1/2 and STAT3,causing the impaired signaling pathway related to HCC progression.Furthermore,based on the construction of a mutant 5′-tiRNA-Gln,the sequence of forming intramolecular G-quadruplex structure is crucial for 5′-tiRNA-Gln to strongly bind EIF4A1 and repress translation.Clinically,5′-tiRNA-Gln expression level is negatively correlated with ARAF,MEK1/2,and STAT3 in HCC tissues.Collectively,these findings reveal that 5′-tiRNA-Gln interacts with EIF4A1 to reduce related mRNA binding through the intramolecular Gquadruplex structure,and this process partially inhibits translation and HCC progression.

Over the past two decades, the development of functional imaging methods has greatly promoted our understanding on the changes of neurons following neurodegenerative disorders, such as Parkin- son＇s disease （PD）. The application of a spatial covariance analysis on 18F-FDG PET imaging has led to the identification of a distinc- tive disease-related metabolic pattern. This pattern has proven to be useful in clinical diagnosis, disease progression monitoring as well as assessment of the neuronal changes before and after clinical treatment. It may potentially serve as an objective biomarker on disease progression monitoring, assessment, histological and func- tional evaluation of related diseases.

Regulating the selectivity toward a target hydrocarbon product is still the focus of CO_(2)electroreduction.Here,we discover that the original surface Cu species in Cu gas-diffusion electrodes plays a more important role than the surface roughness,local pH,and facet in governing the selectivity toward C_(1)or C_(2)hydrocarbons.The selectivity toward C_(2)H_(4) progressively increases,while CH_(4) decreases steadily upon lowering the Cu oxidation species fraction.At a relatively low electrodeposition voltage of 1.5 V,the Cu gas-diffusion electrode with the highest Cu^(δ+)/Cu^(0)ratio favors the pathways of∗CO hydrogenation to form CH_(4) with maximum Faradaic efficiency of 65.4%and partial current density of 228 mA cm^(−2)at−0.83 V vs RHE.At 2.0 V,the Cu gas-diffusion electrode with the lowest Cu^(δ+)/Cu^(0)ratio prefers C-C coupling to form C_(2)+products with Faradaic efficiency topping 80.1%at−0.75 V vs RHE,where the Faradaic efficiency of C_(2)H_(4) accounts for 46.4%and the partial current density of C_(2)H_(4) achieves 279 mA cm^(−2).This work demonstrates that the selectivity from CH_(4) to C_(2)H_(4) is switchable by tuning surface Cu species composition of Cu gas-diffusion electrodes.

Purpose: The exact phenoconversion time from isolated rapid eye movement(REM) sleep behaviour disorder(iRBD) to synucleinopathies remains unpredictable.This study investigated wholebrain dopaminergic damage pattern(DDP) with disease progression and predicted phenoconversion time in individual patients.Methods: Age-matched 33 iRBD patients and 20 healthy controls with 11C-CFT-PET scans were enrolled.The patients were followed up 2-10(6.7 ± 2.0) years.The phenoconversion year was defined as the base year, and every two years before conversion was defined as a stage.Support vector machine with leave-one-out cross-validation strategy was used to perform prediction.Results: Dopaminergic degeneration of iRBD was found to occur about 6 years before conversion and then abnormal brain regions gradually expanded.Using DDP, area under curve(AUC) was 0.879(90% sensitivity and 88.3% specificity) for predicting conversion in 0-2 years, 0.807(72.7% sensitivity and 83.3% specificity) in 2-4 years, 0.940(100% sensitivity and 84.6% specificity) in 4-6 years and 0.879(100% sensitivity and 80.7% specificity) over 6 years.In individual patients, predicted stages correlated with whole-brain dopaminergic levels(r =-0.740, p < 0.001).Conclusion: Our findings suggest that DDP could accurately predict phenoconversion time of individual iRBD patients, which may help to screen patients for early intervention.

As a promising cathode material for sodium ion batteries,honeycomb-ordered layered Na_(3)Ni_(2)Sb O_(6)still suffers from rapid capacity fading because of partially irreversible phase transition.Herein,a substitution of Na+by Rb+with a larger ionic radius in honeycomb layered Na_(3)-xRbxNi_(2)Sb O_(6)is proposed to modulate the interlayer structure.The results unveil that biphasic transition reversibility of the intermediate P′3phase is substantially enhanced,and the structure evolution behavior during the charge/discharge process changes due to the structural modulation,which contributes to a suppression of the unfavorable O_(1)phase and an alleviation of the lattice distortion.Moreover,Rb substituted samples exhibited an improved Na+(de)intercalation thermodynamics and kinetics.Attributed to the modifications,the sample with optimized Rb content delivers superior cycle stability and rate capacity,demonstrating a feasible strategy for suppressing irreversible phase transition and developing high-performance honeycomb layered materials for sodium ion batteries.
