With the diversification of electricity trading forms driven by distributed energy technologies,the continuous growth of blockchain’s chained data structure poses dual challenges to traditional B+tree indexes in terms of query efficiency and storage costs.This paper proposes a sliding window-based learned index construction method(SW-LI).The method consists of two key components.First,block timestamp-height samples are selected using a sliding window and used to train a linear regression model that captures the timestamp-to-height mapping.Second,an adaptive window adjustment mechanism is introduced:when the prediction error within a window exceeds a threshold,the window is contracted to improve local fitting accuracy;otherwise,it is expanded to accelerate global index construction.Together,these components dynamically balance model accuracy and training efficiency.Experimental results demonstrate that when the block count increases from 5000 to 25,000,SW-LI improves index construction efficiency by 69.22%-88.22%compared to Anole.Under a 10,000-block scale,its prediction error is reduced by an average of 80%compared to Sliding Window Search-enhanced Online Gradient Descent(SWS-OGD),with a storage overhead of only 60 KB(25,000 blocks),validating the method’s ability to maintain query accuracy while significantly enhancing indexing efficiency.When the block contains 4000 transactions,the average total query latency of SW-LI is 46.15%lower than that of Anole,which is only 2.7%of the average query latency of SWS-OGD(i.e.,approximately 37 times faster). 展开更多

Towards the development of highly efficient electrochromic coatings,the crystallinity,morphology(e.g.size and shape)of electrochromic nanomaterials,and their charge insertion capacities play a significant role.Herein,we report the structure-dependent colouration effciency in electrochromic coatings based on the use of 0D,1D and 2D tungsten trioxide(WO3)nanostructures.A series of WO3with different nanostructures were prepared and used as working electrodes to fabricate electrochromic devices for smart windows applications.Facile spray coating was applied on fluorine-doped tin oxide(FTO)substrate to make~70%transparent working electrodes to investigate their charge insertion capacities,electrochromic active surface area,and colouration efficiency.Results showed that the 2D WO3nanoflakes displayed the highest diffusion coefficient for the intercalation of 1.52×10-10cm2/s with an increased electrochemical active surface area of 25.10 mF/cm2,a large modulation of optical reflectance(42.63%)with 3.79 s shorter response time for bleaching and a greater colouration efficiency(CE)value(89.29 cm2/C)at 700 nm compared to the CE value for 1D WO3(of 22 cm2/C)and 0D WO3(8 cm2/C).The outcome of this study provides a new insight and valuable contribution to design an efficient electrochromic coating by controlling and optimising the nanostructures of selective electrochromic materials. 展开更多

Dual-band antireflection(DBAR)windows based on surface microstructures offer a promising solution for mid-wave infrared(MWIR)and long-wave infrared(LWIR)co-aperture composite imaging.However,micro-nano manufacturing technology faces significant challenges in efficiently producing highly uniform microstructures with characteristic dimensions of∼1μm across hundreds of millimeters.Here,we report a laser optical field modulation(LOFM)technology for the rapid manufacture of ultra-large-scale arrays of antireflection microholes(ARMHs)on large-aperture and non-perfectly planar windows.LOFM technology,which modulates laser pulses in both temporal and spatial domains,enhances ARMH aspect ratios from 0.1 to 0.8 without reducing manufacturing time,and maintains processing accuracy even with laser focus shifts,thereby addressing inconsistencies in large-area processing.As a proof of concept,approximately 7 billion ARMHs are fabricated on a 100-mm-diameter zinc sulfide(ZnS)window at a rate of 20000 holes per second using LOFM technology assisted by machine learning.The fabricated DBAR ZnS window exhibits ultra-broadband(3.5−14μm),high transmittance(91.1%),wide-angle transmission,wear-resistant,and self-cleaning,making it suitable for environments with multiple interference factors.Dual-band imaging applications demonstrate the significant advantages of DBAR windows in target recognition,multi-scenario robustness,and information acquisition. 展开更多

Three-way control combiner valves(TCCVs)are critical components used in nuclear power plants to regulate the concentration of boron acid for neutron absorption and reactor safety.However,current TCCV designs often suffer from suboptimal control performance and high flow resistance,leading to control deviations and reduced operational efficiency.In this paper,a numerical model based on the standard K–ωturbulence model is established and validated against experimental data to analyze the flow characteristics and local flow resistance of a TCCV.A parametric design method for the throttling windows is proposed,establishing relationships between shape parameters and performance indexes,including control performance and flow resistance.The adaptive non-dominated sorting genetic algorithm(ANSGA-II)is used to optimize the shape parameters of the throttling windows.The optimization results show an improvement in the performance indexes of the TCCV,with the adjustable operating range increasing by 31.0%and the maximum local resistance decreasing by 18.3%.We also introduce the concepts of effective and controllable domains to characterize the inlet backflow phenomena and regulation dead zones,which are crucial for ensuring the reliability and effectiveness of control valves.These findings provide insights for enhancing the design and performance of TCCVs in nuclear power plants. 展开更多

The efficient regulation of sunlight to minimize unnecessary energy exchange through windows plays a vital role in advancing building energy efficiency.However,the inferior stability of cerium-doped tungsten trioxide(CWO)as a near-infrared(NIR)shielding material,combined with the poor mechanical properties of its coatings,poses significant challenges for long-term thermal insulation performance.Here,a hierarchical thermal insulation coating with multifunctional integration has been developed.The inner layer’s excellent NIR shielding performance(94.4%)results in a temperature reduction of 13.6°C,demonstrating outstanding thermal insulation.Meanwhile,the external layer composed of polysilsesquioxane grafted by carboxylated hexafluoropropylene trimer offers exceptional weather resistance due to the low surface energy.The fluorosilicone coating effectively mitigates oxidation of CWO,as evidenced by the retention of NIR shielding performance even after 30 days of exposure to 60°C and 90%relative humidity.Furthermore,the coating demonstrates superior anti-graffiti properties and achieves an ultra-high mechanical strength of 0.49 GPa through precise fluorine content modulation.This hierarchical design integrates high hardness,excellent abrasion resistance,anti-graffiti functionality,transparency,and long-term operational durability into a single smart window system,offering a promising solution for reducing building energy consumption. 展开更多

Bionic anti-reflection windows are critical for enhancing the performance of aerospace infrared detection systems.The manufacturing of anti-reflective microstructures(ARMs),however,faces a significant challenge that the transmittance spectrum is difficult to predict both accurately and swiftly,leading to long-term reliance on blind and inefficient trial-and-error for process optimization.Here,we report a method that integrates machine learning(ML)with femtosecond laser for the rapid customization of high-performance anti-reflection windows.Embedding of the material’s absorption characteristics as a physical constraint into the ML model enables highly accurate prediction across an ultra-broad transmittance spectrum,overcoming the failure of conventional simulations in these intrinsic absorption bands.The trained ML model serves as an intelligent agent to guide the precise control over multiple femtosecond laser parameters,thus converting the costly process of physical trial-and-error into one of efficient virtual screening and iteration.As a proof of concept,an anti-reflective sapphire window was produced that demonstrates broadband(3.3–6.0μm)and high transmittance(~96.8%peak at 4.2μm),along with excellent wide-angle characteristics,mechanical wear resistance,and high-quality imaging capability.This work provides a novel paradigm for rapidly manufacturing high-performance anti-reflective windows,laying the foundation for next-generation optical components. 展开更多

Tandem CO2 electroreduction integrated with carbonylation reactions offers a promising pathway for transforming greenhouse gases into valuable chemical products.The development of efficient CO2-to-CO electrocatalysts operational across wide potential ranges is crucial to address renewable energy fluctuations and facilitate integrated cascade systems.Herein,a Ni single-atom catalyst(SAC)with sulfur doping in the second shell of Ni-N4 is reported.In situ measurements and theoretical calculations demonstrate that the incorporation S atoms not only modulates the electronic configuration of Ni active sites but also enhances H2O adsorption,enabling rapid CO2 hydrogenation into *COOH intermediates even at high potentials.Consequently,the Ni-N-S/CNS catalyst achieves a Faradaic efficiency for CO2-to-CO(FeCO)of 99.3% at-0.7 VRHE and maintains over 90%across pH-universal conditions with ultrawide potential windows:1400 mV(from-0.3 VRHE to-1.7 VRHE)in alkaline media,1200 mV(from-0.7 VRHE to-1.9VRHE)in neutral conditions,and 1000 mV(from-1.3 VRHE to-2.3 VRHE)in acidic environments.Remarkably,this catalyst enables the tandem CO2RR and N-alkylaniline carbonylation process for synthesizing o-aminobenzoates and isatoic anhydrides with high yield.Our findings demonstrate an electrothermocatalytic tandem strategy for cost-effective CO2 conversion and synthesis of high valuable fine chemicals,thereby broadening the scope of its utilization. 展开更多

Although there is an increasing demand for subseasonal prediction,the skill of subseasonal forecasting is currently limited.Under specific oceanic and atmospheric conditions,the subseasonal forecast skill can reach a high level intermittently during a long period.Based on the S2S(subseasonal-to-seasonal)database,the forecast skill windows for surface air temperature(SAT)over East Asia are identified using the PCC(pattern correlation coefficient).Two longlasting windows stand out over the past 30 years—namely,the cold summer of 1993 and the hot summer of 1994 in central and northeastern East Asia.The two windows lasted about two months with high forecast skill in week-3 SAT,and even in week-4 and week-5 SAT.The persistent large-scale oceanic and atmospheric climate anomalies were generally reinforcing in these two summers,providing windows of opportunity for high forecast skill.The combination of the tropical western Pacific sea surface temperature anomaly(SSTA),the Japan Sea-Kuroshio-Kuroshio Extension(K-KE)SSTA,and the North Atlantic SSTA,favored the atmospheric teleconnection,resulting in the cold event in 1993 and the hot event in 1994.The NAO(North Atlantic Oscillation)stayed in its negative or positive phase persistently,contributing to the climate anomalies over East Asia.Climate model experiments with prescribed SST variations demonstrated that the SSTA in the three regions influences East Asian SAT.An index based on the preceding SSTA in the three regions can be used to help identify whether the current forecast case is within the real-time forecast window.This enhances the practical application of the study and has a positive impact on real-time operational forecasting. 展开更多

Nuclear magnetic resonance(NMR)spectroscopy has grown into a formidable tool in biomedical analysis and quantification.However,the lengthy acquisition for highdimensional NMR spectroscopy hinders its broader applications.Non-uniform sampling(NUS)effectively reduces the acquisition time by acquiring partial data.Therefore,the need for reconstruction methods is motivated.The low-rank block Hankel matrix reconstruction method achieves notable reconstruction,but requiring prolonged computational time.In this work,a novel two-directional sliding window method is proposed to reduce the size of the low-rank matrix,effectively mitigating the computational time.Incorporating the parallel computation,further acceleration can be achieved.The numerical experiments on synthetic and real NMR spectroscopy illustrate that,among compared approaches,the proposed method accomplishes reconstruction in the shortest time without compromising the spectral quality. 展开更多

Transparent silica aerogels,which combine high light transmittance with excellent thermal insulation,show broad potential for solar thermal collection and building energy conservation.However,simultaneously achieving high optical transmittance and low thermal conductivity in transparent silica aerogels remains challenging.In this study,transparent insulating silica aerogels with uniform framework structures and pore architectures were synthesized through the supramolecular interaction of methyltrimethoxysilane(MTMS),tetramethoxysilane(TMOS),and the self-assembling template agent F127.The dual silicon sources enabled control over the flexibility and crosslinking density of the aerogel skeleton.F127 formed uniformly sized spherical micelles through self-assembly and acted as a soft template during the sol–gel process,guiding the cooperative formation of the siloxane network.This effectively regulated the pore formation behavior of the aerogel and yielded a more uniform pore structure.The resulting aerogel exhibited high visible-light transmittance(95.9%),low thermal conductivity(0.0258 W/(m K)),and high atmospheric-window emissivity(88%).Compared with tempered glass,the aerogel reduced the temperature by 3.5℃ in energy-saving window applications and increased the temperature by 27.3℃ in solar collector devices.These results indicate that this aerogel has strong potential to simultaneously provide indoor daylighting,thermal insulation,and heat retention for solar devices under direct sunlight. 展开更多

Joining dissimilar materials encounters significant engineering challenges due to the contrast in material properties that makes conventional welding not feasible.Magnetic Pulse Welding(MPW)offers a solidstate joining technique that overcomes these issues by using impact to create strong bonds without melting the substrate materials.This study investigates the weldability of aluminum alloy Al-5754 with Al-7075 and MARS 380 steel,used in armouring solutions of defense systems,by the use of MPW.In this work,weldability windows are investigated by varying standoff distances between the coating material and its substrate(0.25-4.5 mm)and discharge energies(5-13 kJ)with both O-shape and U-shape inductors.Mechanical strength of the welded joints were assessed through single lap shear tests,identifying optimal welding parameters.Then,the velocity profiles of the flyer plates were measured using heterodyne velocimetry to understand the dynamics of the impact.Then,substructures assembled with the optimal welding conditions were subjected to ballistic testing using 7.62 mm×51 mm NATO and 9 mm×19 mm Parabellum munitions to evaluate the resilience of the welds under ballistic impact.The outcomes demonstrate that MPW effectively joins Al-5754 with both Al-7075 and MARS 380,producing robust welds capable of withstanding ballistic impacts under certain conditions.This research advances the application of MPW in lightweight ballistic protection of defense systems,contributing to the development of more resilient and lighter protective structures. 展开更多

Energy-saving buildings(ESBs)are an emerging green technology that can significantly reduce building-associated cooling and heating energy consumption,catering to the desire for carbon neutrality and sustainable development of society.Smart photovoltaic windows(SPWs)offer a promising platform for designing ESBs because they present the capability to regulate and harness solar energy.With frequent outbreaks of extreme weather all over the world,the achievement of exceptional energy-saving effect under different weather conditions is an inevitable trend for the development of ESBs but is hardly achieved via existing SPWs.Here,we substantially reduce the driving voltage of polymerdispersed liquid crystals(PDLCs)by 28.1%via molecular engineering while maintaining their high solar transmittance(Tsol=83.8%,transparent state)and solar modulating ability(ΔTsol=80.5%).By the assembly of perovskite solar cell and a broadband thermal-managing unit encompassing the electrical-responsive PDLCs,transparent high-emissivity SiO2 passive radiation-cooling,and Ag low-emissivity layers possesses,we present a tri-band regulation and split-type SPW possessing superb energy-saving effect in all-season.The perovskite solar cell can produce the electric power to stimulate the electrical-responsive behavior of the PDLCs,endowing the SPWs zero-energy input solar energy regulating characteristic,and compensate the daily energy consumption needed for ESBs.Moreover,the scalable manufacturing technology holds a great potential for the real-world applications. 展开更多

A large number of stone masonry buildings have been constructed in the southeastern oastal region of Fujian Province,China.However,most of these structures exhibit poor seismic performance,likely due to low mortar strength and the absence of effective seismic-resistant system.By analyzing the construction characteristics and seismic vulnerabilities of stone masonry walls between windows,this study proposed a novel retrofitting technique that utilizes POM fiber-reinforced ultra-high performance concrete(POM-UHPC)for mortar joint reinforcement.To investigate the seismic behavior of the retrofitted stone masonry walls between windows,pseudostatic tests were conducted on three wall specimens with an aspect ratio of 1.43(i.e.,one specimen with fullembedding mortar joint reinforcement,one specimen with discrete-point-embedding(localized)mortar joint reinforcement,and one unreinforced specimen for comparison).The results show that the cracking load,initial stiffness,and shear capacity of the specimens with both full-and discrete-point joint reinforcement are significantly increased,and varying degrees of enhancement in their deformation capacity and energy dissipation are observed.When the effective area of POM-UHPC replacing low-strength mortar is similar,the discrete-pointembedding reinforcement method provides a greater improvement in the shear capacity of the wall between windows compared to the full-joint embedding method,but its energy dissipation capacity is lower.In practical engineering in the study area,the discrete-point-embedding mortar joint reinforcement method is recommended as the preferred approach.The findings of this study provide new technical support for the seismic reinforcement of stone masonry buildings in Fujian Province. 展开更多

Objective Fine particulate matter(PM2.5)may impair follicular development;however,the roles of its chemical components and their time-specific effects remain unclear.This study examined how PM2.5and its major components are related to oocyte-related outcomes among women undergoing assisted reproductive technology(ART)and identified critical exposure windows.Methods A total of 51,122 ART cycles were analyzed.Individual exposures to PM2.5 and its components,sulfate(SO42-),nitrate(NO3-),ammonium(NH4+),organic matter(OM),and black carbon(BC),were estimated for three periods:recent(0-3 months),distal(4–12 months),and cumulative(0–12 months).Associations between total,mature,and normally fertilized oocytes were assessed using negative binomial regression.Distributed lag non-linear models(DLNM)identified sensitive windows,and mixture models evaluated joint effects.Results Higher PM2.5 and component exposures were consistently associated with poorer oocyte outcomes,with stronger effects for distal exposure.Two sensitive windows,1 month and 6–11 months before retrieval,were identified.Mixture analyses indicated SO42-and NH4+as the dominant contributors.Conclusion Exposure to PM2.5 showed component-specific and time-dependent reproductive toxicity.Both short-and long-term exposure may reduce oocyte quantity and quality,highlighting the importance of improving air quality to support female reproductive health and ART success. 展开更多

Gallbladder cancer(GBC)remains one of the most lethal gastrointestinal malignancies,characterized by aggressive biology and poor survival.Despite advances in molecular profiling and systemic therapies,innovations have not translated into proportional survival gains in many regions,suggesting underrecognized determinants of prognosis.In this opinion review,we argue that healthcare system logistics represent a critical,modifiable factor influencing GBC outcomes.In intermediate-incidence settings,such as Latin America,many cases are diagnosed incidentally following cholecystectomy.In this context,timely referral for radical re-resection represents a critical component of curative-intent management;however,delays in diagnosis and staging frequently compromise this therapeutic window.Emerging evidence indicates that system-level inefficiencies may impact survival more than traditional clinical variables.We explore the interplay between tumor biology and healthcare delivery,highlighting molecular stratification,surgical centralization,and multidisciplinary coordination.Additionally,we address controversies in incidental GBC,including optimal timing of re-resection and perioperative systemic therapy.We propose that healthcare logistics be formally recognized as a prognostic factor.Bridging the survival gap requires both oncologic advances and structural optimization of care pathways to ensure timely access to curative treatment. 展开更多
