Nanomaterial-based wearable pressure sensors: A minireview

Abstract Wearable pressure sensors have great potential for applications in electronic skin, patient rehabilitation, and touch interfaces. In this paper, state-of-the-art achievements on typical low-dimensional nanostructured wearable pressure sensors and hybrid wearable pressure sensors are reviewed. In the two-dimensional-nanostructure section, two-dimensional transition metal carbides (MXenes) have a large specific area and excellent hydrophilicity, which ensures high sensitivity for pressure detection. Graphene can also represent two-dimensional nanostructured sensing materials due to its excellent transparency and carrier mobility. In the one-dimensional-nanostructure discussion, carbon nanotubes are promising one-dimensional nanostructure sensing materials due to their good mechanical and electronic properties. Silver nanowires have shown potential in the application of conductive fillers due to their excellent electrical properties and flexibility. In the zero-dimensional nanoparticle section, the metal oxide nanoparticles have been shown to be integrated with flexible substrates for sensors due to their large-area electronic uniformity. In the hybrid discussion, the use of electrical and chemical doping is reviewed to combine different nanomaterials to realize sensors with high performance. In each section, the present situation and major challenges are characterized. Next, the evolutions of the methods to overcome these challenges and most significant breakthroughs are demonstrated. In conclusion, future directions that may improve the performance of wearable pressure sensors are summarized.

Récepteur présynaptique métabotropique du Glutamate de type 4 (mGluR4) : fonctions synaptiques et mécanismes d’action dans le cervelet

Les recepteurs metabotropiques au glutamate (mGluRs) jouent un role important dans la regulation de la neurotransmission excitatrice. Les mGluRs du groupe III (mGluR4, 7 et 8), sont connus pour agir en tant qu’autorecepteurs, diminuant la liberation vesiculaire de glutamate. Ces recepteurs couples aux proteines G ont une vaste distribution cerebrale, et sont ainsi souvent retrouves au sein des memes structures, au niveau presynaptique, (excepte les mGluR6 uniquement presents au niveau postysnaptique dans la retine). mGluR4 est tres fortement exprime dans le cortex cerebelleux, et plus precisement au sein des zones actives des terminaisons presynaptiques de l’une des deux afferences excitatrices, les fibres paralleles, ou ils representent les seuls mGluRs du groupe III fonctionnels, ce qui fait de cette structure un modele ideal pour l’etude de ces recepteurs. Au cours de ce travail de these, a l’aide d’enregistrements electrophysiologiques (Patch-Clamp) et de mesures optiques des influx calciques presynaptiques (fluorometrie), nous nous sommes interesse aux mecanismes d’action des mGluR4 aux synapses fibres paralleles – interneurones de la couche moleculaire, mais aussi fibres paralleles – cellule de Purkinje. Nous montrons que les mGluR4 inhibent les canaux calciques voltage-dependants par une voie Gq/PLC/PKC-dependante, et que ces recepteurs mettent egalement en jeu des mecanismes paralleles moins dependants du calcium reposant sur des interactions plus directes avec des proteines impliquees dans les processus d’exocytose.En parallele, nous avons egalement contribue a la caracterisation de deux nouveaux outils pharmacologiques (agonistes orthosteriques) selectifs pour mGluR4, dont le manque actuel constitue une limite majeure a l’etude de ces recepteurs dans nombre de structures cerebrales ou ils sont exprimes.
Hybrid Background Error Covariances for a Limited-Area Deterministic Weather Prediction System

This study introduces an experimental regional assimilation configuration for a 4D ensemble–variational (4D-EnVar) deterministic weather prediction system. A total of 16 assimilation experiments covering July 2014 are presented to assess both experimental regional climatological background error covariances and updates in the treatment of flow-dependent error covariances. The regional climatological background error covariances are estimated using statistical correlations between variables instead of using balance operators. These error covariance estimates allow the analyses to fit more closely with the assimilated observations than when using the lower-resolution global background error covariances (due to shorter correlation scales), and the ensuing forecasts are significantly improved. The use of ensemble-based background error covariances is also improved by reducing vertical and horizontal localization length scales for the flow-dependent background error covariance component. Also, reducing the number of ensemble members employed in the deterministic analysis (from 256 to 128) reduced computational costs by half without degrading the accuracy of analyses and forecasts. The impact of the relative contributions of the climatological and flow-dependent background error covariance components is also examined. Results show that the experimental regional system benefits from giving a lower (higher) weight to climatological (flow-dependent) error covariances. When compared with the operational assimilation configuration of the continental prediction system, the proposed modifications to the background error covariances improve both surface and upper-air RMSE scores by nearly 1%. Still, the use of a higher-resolution ensemble to estimate flow-dependent background error covariances does not yet provide added value, although it is expected to allow for a better use of dense observations in the future.
Genetic studies on the role of type IA DNA topoisomerases in DNA metabolism and genome maintenance in Escherichia coli

DNA supercoiling is important for all cellular processes that require strand separation and is regulated by the opposing enzymatic effects of DNA topoisomerases. Gyrase uses ATP to introduce negative supercoils while topoisomerase I (topA) and topoisomerase IV relax negative supercoils. Cells lacking topoisomerase I are only viable if they have compensatory mutations in gyrase genes that reduce the negative supercoiling level of the chromosome to allow bacterial growth. One such mutation leads to the production of a thermosensitive gyrase (gyrB(Ts)). Gyrase driven supercoiling during transcription in the absence of topoisomerase I causes the accumulation of hypernegatively supercoiled plasmid DNAs due to the formation of R-loops. Overproducing RNase HI (rnhA), an enzyme that degrades the RNA moiety of R-loops, prevents the accumulation of hypernegative supercoils. In the absence of RNase HI alone, R-loops are equally formed and can be used to prime DNA replication independently of oriC/DnaA, a phenomenon known as constitutive stable DNA replication (cSDR). To better understand the link between R-loop formation and hypernegative supercoiling, we constructed a conditional topA rnhA gyrB(Ts) mutant with RNase HI being conditionally expressed from a plasmid borne gene. We found that the DNA of topA rnhA gyrB(Ts) cells was extensively relaxed instead of being hypernegatively supercoiled following the depletion of RNase HI. Relaxation was found to be unrelated to the activity of topoisomerase IV. Cells of topA rnhA gyrB(Ts) formed long filaments full of DNA, consistent with segregation defect. Overproducing topoisomerase III (topB), an enzyme that can perform decatenation, corrected the segregation problems without restoring supercoiling. We found that extracts of topA rnhA gyrB(Ts) cells inhibited gyrase supercoiling activity of wild type cells extracts in vitro, suggesting that the depletion of RNase HI triggered a cell response that inhibited the supercoiling activity of gyrase. Gyrase supercoiling assays in vivo as well as in crude cell extracts revealed that the ATP dependent supercoiling reaction of gyrase was inhibited while the ATP independent relaxation reaction was unaffected. Genetic suppressors of a triple topA rnhA gyrB(Ts) strain that

Legislating deliberative engagement: Is local government in Victoria willing and able?

: Growing dissatisfaction with representative democracy, and concomitantly, the increasing expectation that citizens assert more influence over public policy, have seen the emergence of more participatory and deliberative forms of governance in public management practice. This article explores the attempt of the state government of Victoria, Australia to legislate for mandatory deliberative engagement as part of its local government strategic planning instruments. The ambition of the reform was significant; however, it was almost unanimously rejected by the local government sector. Based on analysis of the key themes that emerged from the submissions made during the three-year Victorian Local Government Act Review process, we explore the limitations and barriers to implementing deliberative engagement practice at a local government level. We demonstrate that whilst the promise of participatory democracy might have been compelling, in the case of Victoria there were a series of contextual and capacity considerations that needed to be taken into account before the implementation of such reforms were pursued.
Adaptive Networks : An Emerging Research Theme on State-Topology Coevolution in Complex Networks (バイオ情報学(BIO) Vol.2010-BIO-23)

Adaptive networks are a particular class of dynamical networks whose topologies and states coevolve over similar time scales. Many real-world complex networks are adaptive networks, including social networks, transportation networks, neural networks and biological networks. This presentation provides a brief overview of the recent rise of research on mathematical/computational modeling and analysis of such networks and discusses current and future research directions.
Investigate the Applicability of CMADS and CFSR Reanalysis in Northeast China

Reanalysis datasets can provide alternative and complementary meteorological data sources for hydrological studies or other scientific studies in regions with few gauge stations. This study evaluated the accuracy of two reanalysis datasets, the China Meteorological Assimilation Driving Datasets for the Soil and Water Assessment Tool (SWAT) model (CMADS) and Climate Forecast System Reanalysis (CFSR), against gauge observations (OBS) by using interpolation software and statistical indicators in Northeast China (NEC), as well as their annual average spatial and monthly average distributions. The reliability and applicability of the two reanalysis datasets were assessed as inputs in a hydrological model (SWAT) for runoff simulation in the Hunhe River Basin. Statistical results reveal that CMADS performed better than CFSR for precipitation and temperature in NEC with the indicators closer to optimal values (the ratio of standard deviations of precipitation and maximum/minimum temperature from CMADS were 0.92, 1.01, and 0.995, respectively, while that from CFSR were 0.79, 1.07, and 0.897, respectively). Hydrological modelling results showed that CMADS + SWAT and OBS + SWAT performed far better than CFSR + SWAT on runoff simulations. The Nash‒Sutcliffe efficiency (NSE) of CMADS + SWAT and OBS + SWAT ranged from 0.54 to 0.95, while that of CFSR + SWAT ranged from −0.07 to 0.85, exhibiting poor performance. The CMADS reanalysis dataset is more accurate than CFSR in NEC and is a suitable input for hydrological simulations.
Effect of Post and Core Materials on Fracture Strength in the Crown Reconstruction of the Root-Treated Tooth

Introduction: Root canal-treated teeth are more prone to failure in functional forces. Post and core procedures are often indicated in these cases. On the other hand, there have been interests in the use of all-ceramic restorations with improved properties in posterior teeth reconstruction. This study aimed to investigate the fracture strength of four different post and core systems in root canal-treated premolars with all-ceramic crowns. Materials and Methods: A total of 48 mandibular premolars were selected and subjected to root canal standard treatment. Afterward, they were divided into four groups of Ni-Cr post and cores casting, glass fiber post/composite core, non-precious gold post and cores casting, and custom-made milled zirconia posts and cores. Each specimen received all-ceramic crowns with zirconia copings and was then loaded by the Zwick device. The amount of fracture resistance by the specimens up to the breaking point was measured and the modes of failure were analyzed in this study. The data were analyzed using analysis of variance and Tukey's honest significance test (α=0.05). Results: The mean fracture strengths of the four groups were 780.59±270, 70±323, 963.24±915.307, and 435.34±220 N, respectively. There were differences between the core and post groups regarding this difference (P=0.000). Conclusion: According to the results, out of the post-and-core procedures used for the reconstruction of prosthetic root canal-treated premolars with all-ceramic crown, the custom-milled zirconia had lower fracture strength, and non-restorable fractures were more prevalent in these posts.
Min-Max Tours and Paths for Task Allocation to Heterogeneous Agents

We consider a scenario consisting of a set of heterogeneous mobile agents and a set of tasks dispersed over a geographic area. The agents are partitioned into different types. The tasks are partitioned into specialized tasks that can only be done by agents of a certain type, and generic tasks that can be done by any agent. Given this scenario, we address the problem of allocating these tasks among the available agents (subject to type compatibility constraints) while minimizing the maximum travel cost for any agent. We first look at the heterogeneous agent cycle problem where agents start at a common depot and need to tour the set of tasks allocated to them before returning to the depot. We provide a 5-approximation algorithm to solve this problem, regardless of the total number of agents and the number of agents of each type. We then consider the heterogeneous agent path problem (HAPP) where agents can start from arbitrary locations and are not constrained to return to their start location. We consider two approaches to solve HAPP. The first approach yields a 15-approximation factor, while the second yields a factor of 16.
Using Energy Storage to Relief Transformer Overloading after Coal-Fire Generator Retirement

Energy storage system (ESS) is believed to be a significant source of power system operational flexibility given renewable generation with high penetration. This work reports a unique scenario of relieving the overloading of a 500kV transformer after the retirement of a coal-fire generator. ESS is proven to be an ideal solution in terms of technical feasibility and economic performance. A look-ahead operation strategy is to utilize ESS to mitigate the identified transformer overloading bottleneck. A case study using a synthetic version of Zhejiang power grid confirms the effectiveness of the proposed ESS based approach.
Tropical water vapour in the lower stratosphere and its relationship to tropical/extratropical dynamical processes in ERA5

Stratospheric water vapour (SWV), in spite of its low concentration in the stratosphere as compared to the troposphere, contributes significantly to the surface energy budget and can have an influence on the surface climate. This study investigates the dynamical processes that determine SWV on interannual to decadal time‐scales. First, we evaluate two SWV reanalysis products and show that SWV is better represented in a new‐generation reanalysis product, ERA5, than in its predecessor, ERA‐Interim. In particular, it is shown that SWV in ERA5 is highly consistent with observational data obtained from the SPARC Data Initiative Multi‐Instrument Mean (SDI MIM). Second, we investigate the variability of tropical SWV and its relationship to dynamical stratospheric variables. The analyses show that the interannual variability in the tropical lower‐stratospheric water vapour is closely linked to the tropical Quasi‐Biennial Oscillation (QBO). When westerlies occupy the middle stratosphere and easterlies the lower stratosphere, a decrease is observed in lower‐stratospheric water vapour due to a colder tropical tropopause and a QBO‐induced enhanced residual circulation. On decadal time‐scales, the composite analysis of the boreal winter in two typical periods shows that less SWV is related to a warm anomaly in the North Atlantic sea‐surface temperature, which leads to stronger upward propagation of planetary wave activity at high latitudes, a weaker polar vortex and an enhanced residual circulation. The opposite occurs during periods with higher concentrations of SWV.
Evaluation of tyre/road noise and texture interaction on rubberised and conventional pavements using CPX and profiling measurements

Road traffic noise is the most common source of environmental pollution in urban areas, and therefore, the study of noise mitigation actions is fundamental for urban planning. The use of low noise road surfaces is one of the most widespread intervention since it acts directly on the source of road traffic noise, represented by tyre/road interaction. In this work, the interaction between texture and tyre/road noise was studied from an experimental point of view, by comparing CPX and road texture measurements on rubberised and standard road surfaces. Tyre deformation was addressed by taking into account the indenter method proposed by Sandberg and Goubert in 2018. Regressions of CPX and enveloped road texture levels were performed separating rubberised from reference surfaces, and parallelism tests were performed on the slopes. Results show that the use of rubber influences the interaction of road texture and noise, especially at high frequencies.
Efficient matrix-free direction method with line search for solving large-scale system of nonlinear equations

We proposed a matrix-free direction with an inexact line search technique to solve system of nonlinear equations by using double direction approach. In this article, we approximated the Jacobian matrix by appropriately constructed matrix-free method via acceleration parameter. The global convergence of our method is established under mild conditions. Numerical comparisons reported in this paper are based on a set of large-scale test problems and show that the proposed method is efficient for large-scale problems.
Serum mineral status during pregnancy in cows

In this study, the serum concentrations ofcalcium (Ca), zinc (Zn), copper (Cu), iron (Fe), potassium (K) and sodium (Na) in 12 cows, 3-8 year old, during pregnancy and post-partum, and the relations among stich parameters were researched. Parallel variations of serum Cn and eu concentrations were noticed. They significantly increased from the tifth month, were maxima on the sixth month and thereafter they gradually declined until the parturition day. Zn concentrations were found modified (from the third 1110nth) and remained elevated throughout the pregnancy, with maximum values on the fourth and fifth months. fe, Na and K tended to decrease during pregnancy. From the third to the eighth month a significant decline of Fe was observed, and Kconcentration were particularly lower on the fifth and the seventh month. Na concentrations fluctuated, marked decrease ofNa were observed on the fourth month and on the ninth month and during postpartum. The important correlations were determined between Ca-Cu, Ca-Zn, Ca-Fc, Cu-Zn in various months of pregnancy and the clay of delivery. A significant relation was found between Fe-Zn during the pregnancy. Any change due to the delivery status was not determined in the levels ofCa, Cu, Zn, Fe, K and Na during the pregnancy and postparturition. In conclusion, it was agreed that the levels of serum Ca, Cll and Zn levels decreased as determllled during the last months of the pregnancy and postparturition.
Du texte à l’intertexte. Le palimpseste Macron au révélateur de l’Intelligence artificielle

L’intertexte est la condition de l’interprétation de tout texte. Cependant, sa matérialisation, son explicitation, son implémentation ont toujours paru difficile pour la linguistique textuelle. Cette contribution propose une matérialisation de l’intertexte au sein decorpus réflexifs numériques, et convoque de manière originale l’intelligence artificielle (deep learning, modèle convolutionnel) et la logométrie pour explorer de manière systématique l’intertexte ainsi matérialisé. Pour cette étude, nous postulons que le corpus élyséen depuis 1958 constitue l’intertexte des discours d’Emmanuel Macron, dans lequel le président puise de manière consciente ou inavouée pour construire ses discours. A titre d’exemple, nous mettons ainsi au jour automatiquement les empreintes grammaticales de Giscard dans le discours de Macron, et les emprunts lexicaux que le nouveau président concède à de Gaulle.
