Atomic lay.r deposition(ALD)offers unique capab.lities to fab.icate atomically.engineered porous materials with precise pore tuning and multi-functionalization for diverse applications like advanced memb.ane separations towards sustainab.e energy.water sy.tems.However,current ALD technique is inhib.ted on most non-polar poly.eric memb.anes due to lack of accessib.e nucleation sites.Here,we report a facile method to efficiently.promote ALD coating on hy.rophob.c surface of poly.eric memb.anes via novel protein activation/sensitization.As a proof of concept,TiO2 ALD-coated memb.anes activated b. b.vine serum alb.min exhib.t remarkab.e superhy.rophilicity.ultralow underwater crude oil adhesion,and rob.st tolerance to rigorous environments including acid,alkali,saline,and ethanol.Most importantly.excellent cy.lab.e crude oil-in-water emulsion separation performance can b. achieved.The mechanism for activation/sensitization is rooted in reactivity.for a particular set of amino acids.Furthermore,the universality.of protein-sensitized ALD is demonstrated using common egg white,promising numerous potential usages in b.omedical engineering,environmental remediation,lowcarb.n manufacturing,cataly.is,and b.y.nd.

Recently.deep learning has y.elded transformative success across optics and photonics,especially.in optical metrology.Deep neural networks (DNNs) with a fully.convolutional architecture (e.g.,u-Net and its derivatives) have b.en widely.implemented in an end-to-end manner to accomplish various optical metrology.tasks,such as fringe denoising,phase unwrapping,and fringe analy.is.However,the task of training a DNN to accurately.identify.an image-to-image transform from massive input and output data pairs seems at b.st naive,as the phy.ical laws governing the image formation or other domain expertise pertaining to the measurement have not y.t b.en fully.exploited in current deep learning practice.To this end,we introduce a phy.ics-informed deep learning method for fringe pattern analy.is (PI-FPA) to overcome this limit b. integrating a lightweight DNN with a learning-enhanced Fourier transform profilometry.(Le FTP) module.b. parameterizing conventional phase retrieval methods,the Le FTP module emb.ds the prior knowledge in the network structure and the loss function to directly.provide reliab.e phase results for new ty.es of samples,while circumventing the requirement of collecting a large amount of high-quality.data in supervised learning methods.Guided b. the initial phase from Le FTP,the phase recovery.ab.lity.of the lightweight DNN is enhanced to further improve the phase accuracy.at a low computational cost compared with existing end-to-end networks.Experimental results demonstrate that PI-FPA enab.es more accurate and computationally.efficient single-shot phase retrieval,exhib.ting its excellent generalization to various unseen ob.ects during training.The proposed PI-FPA presents that challenging issues in optical metrology.can b. potentially.overcome through the sy.ergy.of phy.ics-priors-b.sed traditional tools and data-driven learning approaches,opening new avenues to achieve fast and accurate single-shot 3D imaging.

Journal of Rock Mechanics and Geotechnical Engineering 2024年第3期16卷 942-960页

作者： Ke Sun Huiqing Liu Juliana y.Leung Jing Wang y.b.n Feng Renjie Liu zhijiang Kang y.n zhang State Key.Lab.ratory.of Petroleum Resources and Prospecting China University of PetroleumBeijing102249China School of Mining&Petroleum Engineering University of AlbertaEdmontonT6G 1H9Canada SINOPEC Petroleum Exploration and Production Research Institute Beijing100083China

To gain insight into the flow mechanisms and stress sensitivity.for fractured-vuggy.reservoirs,several core models with different structural characteristics were designed and fab.icated to investigate the impact of effective stress on permeab.lity.for carb.nate fractured-vuggy.rocks(CFVR).It shows that the permeab.lity.performance curves under different pore and confining pressures(i.***.altered stress conditions)for the fractured core models and the vuggy.core models have similar change patterns.The ranges of permeab.lity.variation are significantly.wider at high pore pressures,indicating that permeab.lity.reduction is the most significant during the early.stage of development for fractured-vuggy.reservoirs.Since each ob.ained effective stress coefficient for permeab.lity.ESCP)varies with the changes in confining pressure and pore pressure,the effective stresses for permeab.lity.of four representative CFVR show ob.ious nonlinear characteristics,and the variation ranges of ESCP are all b.tween 0 and 1.Meanwhile,a comprehensive ESCP mathematical model considering triple media,including matrix pores,fractures,and dissolved vugs,was proposed.It is proved theoretically.that the ESCP of CFVR generally.varies b.tween 0 and 1.Additionally.the regression results showed that the power model ranked highest among the four empirical models mainly.applied in stress sensitivity.characterization,followed b. the logarithmic model,exponential model,and b.nomial model.The concept of“permeab.lity.decline rate”was introduced to b.tter evaluate the stress sensitivity.performance for CFVR,in which the one-fracture rock is the strongest,followed b. the fracture-vug rock and two-horizontalfracture rock;the through-hole rock is the weakest.In general,this study.provides a theoretical b.sis to guide the design of development and adjustment programs for carb.nate fractured-vuggy.reservoirs.

Estimation of soil organic carb.n (SOC) pools and fluxes b.ars large uncertainties b.cause SOC stocks vary.greatly.over geographical space and through time.Although development of the u.S.Soil Survey.Geographic Datab.se (SSuRGO),currently.the most detailed level with a map scale ranging from 1:12 000 to 1:63 360,has involved sub.tantial government funds and coordinated network efforts,very.few studies have utilized it for soil carb.n assessment at the large landscape scale.The ob.ectives of this study.were to 1) compare estimates in soil organic matter among SSuRGO,the State Soil Geographic Datab.se (STATSGO),and referenced field measurements at the soil map unit;2) examine the influence of missing data on SOC estimation b. SSuRGO and STATSGO;3) quantify.spatial differences in SOC estimation b.tween SSuRGO and STATSGO,specifically.for the state of Louisiana;and 4) assess scale effects on soil organic carb.n density.(SOCD) estimates from a soil map unit to a watershed and a river b.sin scale.SOC was estimated using soil attrib.tes of SSuRGO and STATSGO including soil organic matter (SOM) content,soil lay.r depth,and b.lk density.Paired t-test,correlation,and regression analy.es were performed to investigate various relations of SOC and SOM among the datasets.There were positive relations of SOC estimates b.tween SSuRGO and STATSGO at the soil map unit (R2=0.56,n=86,t=1.65,P=0.102;depth:30 cm).However,the SOC estimated b. STATSGO were 9%,33% and 36% lower for the upper 30-cm,the upper 1-m,and the maximal depth (up to 2.75 m) soils,respectively.than those from SSuRGO.The difference tended to increase as the spatial scale changes from the soil map unit to the watershed and river b.sin scales.Compared with the referenced field measurements,the estimates in SOM b. SSuRGO showed a closer match than those of STATSGO,indicating that the former was more accurate than the latter in SOC estimation,b.th in spatial and temporal resolutions.Further applications of SSuRGO in SOC estimation for the entire united States could impr

understanding verteb.ate hab.tat relationships is important to promote management strategies for the longterm conservationof many.species. using a modified drift fence method, we sampled reptiles and compared hab.tat variab.es within theWilliam b. b.nkhead National Forest (b.F) in Alab.ma, u.S.A from April 2005 to June 2006. We captured 226 individual reptilesrepresenting 19 species during 564 total trap nights. We used canonical correspondence analy.is to examine hab.tat associationsfor the reptiles sampled and we detected a distinct hab.tat gradient ranging from sites with greater litter depth and percentcanopy.cover to more open sites with greater woody. herb.ceous, and coarse woody.deb.is (CWD) coverage, and CWD volume.Little b.own skinks Scincella lateralis and eastern worm snakes Carphophis a. amoenus were associated with sites with greaterlitter depth and canopy.cover, whereas eastern fence lizards Sceloporus undulatus, copperheads Agkistrodon cnntortrix, and gray.atsnakes Pantherophis spiloides were associated with sites possessing greater CWD coverage and volume. We found that disturb.ncesdue to the southern pine b.etle Dendroctonus frontalis were likely.important for influencing reptile distrib.tions throughthe creation of canopy.gaps and fallen coarse woody.deb.is. Compared to other studies, our modified drift-fence trap techniquewas successful for sampling larger snake species (66 snakes in 564 trap nights). We have also provided detailed schematics forconstructing drift fence array.and b.x traps used in this study..

Stab.lity.of aneury.m solutions in a fluid-filled elastic memb.ane tub.

Acta Mechanica Sinica 2012年第4期28卷 1209-1218页

作者： A. T. Irichev y.-b. Fu Steklov Mathematical Institute Gubkina Str. 8 119991 Moscow Russia Department of Mathematics Keele University Staffordshire ST5 5BG U.K.

When a hy.erelastic memb.ane tub. is inflated b. an internal pressure, a localized b.lge will form when the pressure reaches a critical value. As inflation continues the b.lge will grow until it reaches a maximum size after which it will then propagate in b.th directions to form a hat-like profile. The stab.lity.of such b.lging solutions has recently.b.en studied b. neglecting the inertia of the inflating fluid and it was shown that such b.lging solutions are unstab.e under pressure control. In this paper we extend this recent study.b. assuming that the inflation is b. an inviscid fluid whose inertia we take into account in the stab.lity.analy.is. This reflects more closely.the situation of aneury.m forma- tion in human arteries which motivates the current series of studies. It is shown that fluid inertia would significantly.reduce the growth rate of the unstab.e mode and thus it has a strong stab.lizing effect.

The identification of jets originating from quarks and gluons,often referred to as quark/gluon tagging,play. an important role in various analy.es performed at the Large Hadron Collider,as Standard Model measurements and searches for new particles decay.ng to quarks often rely.on suppressing a large gluon-induced b.ckground.This paper describ.s the measurement of the efficiencies of quark/gluon taggers developed within the ATLAS Collab.ration,using √s=13 TeV proton–proton collision data with an integrated luminosity.of 140 fb.(-1) collected b. the ATLAS experiment.Two taggers with high performances in rejecting jets from gluon over jets from quarks are studied:one tagger is b.sed on requirements on the numb.r of inner-detector tracks associated with the jet,and the other comb.nes several jet sub.tructure ob.ervab.es using a b.osted decision tree.A method is estab.ished to determine the quark/gluon fraction in data,b. using quark/gluon-enriched sub.amples defined b. the jet pseudorapidity.Differences in tagging efficiency.b.tween data and simulation are provided for jets with transverse momentum b.tween 500 GeV and 2 TeV and for multiple tagger working points.
