The negative and positive bias temperature instabilities are investigated on p-channel and n-channel TFTs with four different combinations.The stress-induced hump in the subthreshold region is observed for PBTI on p-channel TFTs and NBTI on n-channel TFTs.The hump is attributed to the edge transistors along the channel width direction.Higher electric field at the corners induces more trapped carriers in the insulator as compared to channel transistor.In contrast,no humps are observed for NBTI on p-channel TFTs and PBTI on n-channel TFTs.For NBTI on p-channel TFTs,the interface traps are generated by breaking the si-H bonds and are responsible for the negativeΔV.On the other hand,electrons are trapped in the insulator and induce positiveΔV for PBTI on n-channel TFTs.

Trigeminal-specific stimulants have been shown to activate different receptors preferentially and this likely accounts for variation in sensory perception.It is unclear whether trigeminal sensitivity is similar across different transient receptor potential(TRP)receptors or if dysfunction of different receptors results in differing patient symptoms.Therefore,a prospective cohort study was conducted,consisting of trigeminal lateralization testing with three different stimulants(eucalyptol,isothiocyanate,acetic acid),olfaction testing with sniffin'sticks,and measurement of various patient‐reported outcome measures(PROMs).A total of 50 participants were enrolled across the olfactory spectrum.Mean TDI score was 27.1±8.3(range 7.0–39.5)with 38%normosmic and 62%dysosmic.Mean trigeminal lateralization scores out of 20 in the overall cohort were 16.18(2.78)for eucalyptol,14.94(3.49)for mustard oil,and 15.28(3.68)for vinegar.Eucalyptol showed a significant correlation with threshold scores of sniffin'sticks.A significant correlation was found between acetic acid and various PROMs.None of the lateralization scores of the trigeminal stimulants correlated to each other significantly and there was no correlation to age.The lack of correlation suggests that the measured sensitivity of one type of TRP receptor may not translate to similar sensitivity of the other receptors.Additional investigations with TRPV1 and TRPA1 agonists are needed to corroborate our findings.

The rapid development of clean and renewable energy technologies represented by wind and solar energy,as well as the continuous growth of load demand,have put forward higher requirements for the safe operation of the power equipment.The performance of power equipment based on traditional dielectric materials is often limited by various defects generated during molding,transportation,assembly,and operation,which cannot meet the reliability requirements of power systems in the new situation.Nondestructive detection is an essential technical method in industrial development,which can detect and evaluate the defect and damage status of in-service equipment,key components,and materials without damaging the obj.ct.

Removal of boric acid from seawater and wastewater using reverse osmosis membrane technologies is imperative and yet remains inadequately addressed by current commercial membranes.Existing research efforts performed post-modification of reverse osmosis membranes to enhance boron rej.ction,which is usually accompanied by substantial sacrifice in water permeability.This study delves into the surface engineering of low-pressure reverse osmosis membranes,aiming to elevate boron removal efficiency while maintaining optimal salt rej.ction and water permeability.Membranes were modified by the self-polymerization and co-deposition of dopamine and polystyrene sulfonate at varying ratios and concentrations.The surfaces became smoother and more hydrophilic after modification.The optimum membrane exhibited a water permeability of 9.2±0.1 L·m^(-2)·h^(-1)·bar^(-1),NaCl rej.ction of 95.8%±0.3%,and boron rej.ction of 49.7%±0.1%and 99.6%±0.3%at neutral and alkaline pH,respectively.The water permeability is reduced by less than 15%,while the boron rej.ction is 3.7 times higher compared to the blank membrane.This research provides a promising avenue for enhancing boron removal in reverse osmosis membranes and addressing water quality concerns in the desalination process.

Perfluorobutanesulfonate(PFBs)is an emerging pollutant capable of potently disrupting the sex and thyroid endocrine systems of teleosts.However,the hypoxic and temporal variation in PFBs endocrine disrupting toxicity remain largely unknown.In the present study,adult marine medaka were exposed to environmentally realistic concentrations of PFBs(0 and 10μg/L)under normoxia or hypoxia conditions for 7 days,aiming to explore the interactive behavior between PFBs and hypoxia.In addition,PFBs singular exposure was extended till 21days under normoxia to elucidate the time-course progression in PFBs toxicity.The results showed that hypoxia inhibited the growth and caused the suspension of egg spawn regardless of PFBs exposure.With regard to the sex endocrine system,7-day PFBs exposure led to an acute stimulation of transcriptional profiles in females,which,subsequently,recovered after the 21-day exposure.The potency of hypoxia to disturb the sex hormones was much stronger than PFBs.A remarkable increase in estradiol concentration was noted in medaka blood after hypoxia exposure.Changes in sex endocrinology of coexposed fish were largely determined by hypoxia,which drove the formation of an estrogenic environment.PFBs further enhanced the endocrine disrupting effects of hypoxia.However,the hepatic synthesis of vitellogenin and choriogenin,two commonly used sensitive biomarkers of estrogenic activity,failed to initiate in response to the estrogen stimulus.Compared to sex endocrine system,disturbances in thyroidal axis by PFBs or hypoxia were relatively mild.Overall,the present findings will advance our toxicological understanding about PFBs pollutant under the interference of hypoxia.

Lithium–oxygen battery with ultrahigh theoretical energy density is considered a highly competitive next-generation energy storage device,but its practical application is severely hindered by issues such as difficult decomposition of discharge products at present.Here,we have developed N-doped carbon anchored atomically dispersed Ru sites cathode catalyst with open hollow structure(h-RuNC)for Lithium–oxygen battery.On one hand,the abundance of atomically dispersed Ru sites can effectively catalyze the formation and decomposition of discharge products,thereby greatly enhancing the redox kinetics.On the other hand,the open hollow structure not only enhances the mass activity of atomically dispersed Ru sites but also improves the diffusion efficiency of catalytic molecules.Therefore,the excellent activity from atomically dispersed Ru sites and the enhanced diffusion from open hollow structure respectively improve the redox kinetics and cycling stability,ultimately achieving a high-performance lithium–oxygen battery.

Neural networks are powerful tools for approximating high dimensional data that have been used in many contexts,including solution of partial differential equations(PDEs).We describe a solver for multiscale fully nonlinear elliptic equations that makes use of domain decomposition,an accelerated schwarz framework,and two-layer neural networks to approximate the boundary-to-boundarymap for the subdomains,which is the key step in the schwarz procedure.Conventionally,the boundary-to-boundary map requires solution of boundary-value elliptic problems on each subdomain.By leveraging the compressibility of multiscale problems,our approach trains the neural network offline to serve as a surrogate for the usual implementation of the boundary-to-boundary map.Our method is applied to a multiscale semilinear elliptic equation and a multiscale p-Laplace equation.In both cases we demonstrate significant improvement in efficiency as well as good accuracy and generalization performance.

The conversation machine comprehension(MC)task aims to answer questions in the multi-turn conversation for a single passage.However,recent approaches don’t exploit information from historical conversations effectively,which results in some references and ellipsis in the current question cannot be recognized.In addition,these methods do not consider the rich semantic relationships between words when reasoning about the passage text.In this paper,we propose a novel model GraphFlow+,which constructs a context graph for each conversation turn and uses a unique recurrent graph neural network(GNN)to model the temporal dependencies between the context graphs of each turn.specifically,we exploit three different ways to construct text graphs,including the dynamic graph,static graph,and hybrid graph that combines the two.Our experiments on CoQA,QuAC and DoQA show that the GraphFlow+model can outperform the state-of-the-art approaches.
