Background Acupuncture involving the limb region may be effective for stroke rehabilitation clinically,but the visualised and explanatory evidence is *** objectives were to assess the specific effects of acupuncture for ischaemic stroke(IS)patients with hemiparesis and investigate its therapy-driven modification in functional *** IS patients were randomly assigned(2:1.to receive 1. sessions of hand-foot 1. needles acupuncture(HA,n=30)or non-acupoint(NA)acupuncture(n=1.),enrolling gender-matched and age-matched healthy controls(HCs,n=34).The clinical outcomes were the improved Fugl-Meyer Assessment scores including upper and lower extremity(ΔFM,ΔFM-UE,ΔFM-LE).The neuroimaging outcome was voxel-mirrored homotopic connectivity(VMHC).Static and dynamic functional connectivity(sFC,DFC)analyses were used to study the neuroplasticity *** 46 ISs(mean(SD)age,59.37(1..36)years)and 34 HCs(mean(SD)age,52.88(9.69)years)were included in the per-protocol analysis of clinical and *** clinical,ΔFM scores were 5.00 in HA group and 2.50 in NA group,with a dual correlation betweenΔFM andΔVMHC(angular:r=0.696,p=0.000;cerebellum:r=-0.71.,p=0.000)fitting the linear regression model(R2=0.828).In neuroimaging,ISs demonstrated decreased VMHC in bilateral postcentral gyrus and cerebellum(Gaussian random field,GRF corrected,voxel p1.cluster p1.,accuracy=0.7500).Following acupuncture,VMHC in bilateral superior frontal gyrus orbital part was increased with cerebro-cerebellar changes,involving higher sFC between ipsilesional superior frontal gyrus orbital part and the contralesional orbitofrontal cortex as well as cerebellum(GRF corrected,voxel p1.cluster p1.cluster p<0.05),with integration states transforming into segregation states overall(

Multi-sensor multispectral reconstruction framework based on projection and reconstruction

Science China(Information Sciences) 2024年第3期67卷 246-262页

作者： Tianshuai LI tianzhu LIU Xian LI Yanfeng GU Yukun WANG Yushi CHEN School of Electronics and Information Engineering Harbin Institute of Technology Heilongjiang Province Key Laboratory of Space-Air-Ground Integrated Intelligent Remote Sensing

The scarcity and low spatial resolution of hyperspectral images(HSIs) have become a major problem limiting the application of the images. In recent years, spectral reconstruction(SR) has been applied to convert multispectral images(MSIs) with abundant quantities and high spatial resolution into HSIs. With the launch of several new multispectral(MS) satellites with a short repeat period, the simultaneous acquisition of images from multiple MS sensors in the same area is gradually becoming feasible. Unfortunately, existing SR methods only consider the reconstruction of the MSIs of a single sensor without considering using MSIs from different MS sensors to obtain a better construction effect through their complementary bands. However,multi-sensor SR is characterized by two problems: inconsistency in the amplitude information of real multisensor imaging and difficulty in the extraction of the complex correlations of bands from different *** solve these problems, this paper proposes a multi-sensor SR framework based on a two-step approach in which the problems of amplitude inconsistency and band information extraction are solved using an ideal projection network and an ideal multi-sensor SR network, respectively. The effectiveness of the proposed method is verified by experiments on three datasets.

Abundant mafic-felsic intrusions distributed in the Altyn Orogen record orogenic histories related to Proto-Tethys and Paleo-Tethys *** U-Pb dating of the intrusive rocks in the eastern Altyn Orogen identifies at least three major tectono-magmatic episodes,yielding ages of∼426,∼376–373 and∼269–254 *** first two emplacement episodes correspond to the post-collisional magmatism in the Altyn ***∼426 Ma granitoids possess adakitic characteristics coupled with enriched isotopes,suggesting that they originated from partial melting of thickened lower continental crust induced by upwelling asthenospheric mantle after slab break-off of the South Altyn Ocean ***,the∼376–373 Ma mafic-intermediate rocks and coeval granitoids represent a large thermal event that involved mantle melting with induced new juvenile lower continental crust melting in a post-collisional extensional ***,the∼254 Ma diabase dykes intruded into the∼269 Ma granitoids,which were related to the widespread Late Paleozoic magmatism resulting from Paleo-Tethys Ocean ***-collisional magmatism in the Altyn Orogen significantly enhances understanding of the tectono-magmatic evolution in the northern Tibetan *** penetrative influence of Paleo-Tethys Ocean subduction was more extensive than previously thought.

Ternary content-addressable memory(TCAM) is an indispensable component of lookup tables in switches or ***, it suffers from expensive and inflexible update operations and cannot fulfill the demand for rule updates in switches enabling software-defined networking(SDN). The main reason is that TCAM stores rules from top to bottom in decreasing order of priority for disambiguation. Updating a TCAM is similar to the insertion sort that takes O(n) time,
