Assessing the Connectivity of a Regional Fractured Aquifer Based on a Hydraulic Conductivity Field Reversed by Multi-Well Pumping Tests and Numerical Groundwater Flow Modeling

Aquifer connectivity could greatly affect groundwater flow and further control the contaminant transport in fractured medium. However, assessing connectivity of fractured aquifer at regional scales is still a challenge because such connectivity is difficult to be measured directly. This study proposes a framework for assessing connectivity of a fractured aquifer, with Qitaihe area, Heilongjiang Province, northeastern China as an illustrating study area. The 3-D finite difference numerical models were established to interpret the results of three multi-well pumping tests and inversely estimate the distribution of hydraulic conductivity (K) in the fractured aquifer. A static connectivity metric of the minimum hydraulic resistance (MHR) was calculated, based on the optimized K-field, to evaluate the hydraulic connectivity in the aquifer, and the corresponding least resistance paths (LRPs) were identified. The results indicate a better horizontal connectivity in the fractured aquifer in the northeastern and middle parts than in the southwestern part of the study area. The identified LRP indicated that the preferential flow channels at regional scales were controlled mainly by aquifer connectivity instead of local high-K zones. The results of this study can provide a method for aquifer connectivity estimation at regional scales.
Wafer-scale heterogeneous integration of self-powered lead-free metal halide UV photodetectors with ultrahigh stability and homogeneity

Large-scale growth and heterogeneous integration with existing semiconductors are the main obstacles to the application of metal halide perovskites in optoelectronics. Herein, a universal vacuum evaporation strategy is presented to prepare copper halide films with wafer-scale spatial homogeneity. Benefiting from the electric field manipulation method, the built-in electric fields are optimized and further boost the self-powered UV photodetecting performances of common wide-bandgap semiconductors by more than three orders of magnitude. Furthermore, with effective modulation of the interfacial charge dynamics, the as-fabricated GaN-substrate heterojunction photodetector demonstrates an ultrahigh on/off ratio exceeding 10 7, an impressive responsivity of up to 256 mA W~(–1), and a remarkable detectivity of 2.16 × 10~(13) Jones at 350 nm, 0 V bias. Additionally, the device exhibits an ultrafast response speed (t r/t d = 716 ns/1.30 ms), an ultra-narrow photoresponse spectrum with an FWHM of 18 nm and outstanding continuous operational stability as well as long-term stability. Subsequently, a 372-pixel light-powered imaging sensor array with the coefficient of variation of photocurrents reducing to 5.20% is constructed, which demonstrates exceptional electrical homogeneity, operational reliability, and UV imaging capability. This strategy provides an efficient way for large-scale integration of metal halide perovskites with commercial semiconductors for miniature optoelectronic devices.
Adaptive fuze-warhead coordination method based on BP artificial neural network

The appropriate fuze-warhead coordination method is important to improve the damage efficiency of air defense missiles against aircraft targets. In this paper, an adaptive fuze-warhead coordination method based on the Back Propagation Artificial Neural Network (BP-ANN) is proposed, which uses the parameters of missile-target intersection to adaptively calculate the initiation delay. The damage probabilities at different radial locations along the same shot line of a given intersection situation are calculated, so as to determine the optimal detonation position. On this basis, the BP-ANN model is used to describe the complex and highly nonlinear relationship between different intersection parameters and the corresponding optimal detonating point position. In the actual terminal engagement process, the fuze initiation delay is quickly determined by the constructed BP-ANN model combined with the missiletarget intersection parameters. The method is validated in the case of the single-shot damage probability evaluation. Comparing with other fuze-warhead coordination methods, the proposed method can produce higher single-shot damage probability under various intersection conditions, while the fuzewarhead coordination effect is less influenced by the location of the aim point.
Pedotransfer functions for predicting bulk density of coastal soils in East China

Soil bulk density (BD) is an important physical property and an essential factor for weight-to-volume conversion. However, BD is often missing from soil databases because its direct measurement is labor-intensive, time-consuming, and sometimes impractical, particularly on a large scale. Therefore, pedotransfer functions (PTFs) have been developed over several decades to predict BD. Here, six previously revised PTFs (including five basic functions and stepwise multiple linear regression (SMLR)) and two new PTFs, partial least squares regression (PLSR) and support vector machine regression (SVMR), were used to develop BD-predicting PTFs for coastal soils in East China. Predictor variables included soil organic carbon (SOC) and particle size distribution (PSD). To compare the robustness and reliability of the PTFs used, the calibration and prediction processes were performed 1 000 times using the calibration and validation sets divided by a random sampling algorithm. The results showed that SOC was the most important predictor, and the revised PTFs performed reasonably although only SOC was included. The PSD data were useful for a better prediction of BD, and sand and clay fractions were the second and third most important properties for predicting BD. Compared to the other PTFs, the PLSR was shown to be slightly better for the study area (the average adjusted coefficient of determination for prediction was 0.581). These results suggest that PLSR with SOC and PSD data can be used to fill in the missing BD data in coastal soil databases and provide important information to estimate coastal carbon storage, which will further improve our understanding of sea-land interactions under the conditions of ongoing global warming.
Terahertz shaping technology based on coherent beam combining

The generation of terahertz (THz) waves by focusing a femtosecond pulsed laser beam at a distance is able to overcome the strong absorption properties of air and has rapidly attracted the attention of industry. However, the poor directionality of the THz wave radiation generated by this method is not conducive to THz wave applications. By controlling the morphology of the ultrafast laser-excited plasma filament and its electron density distribution through coherent beam combining technology, we achieve direct THz beam shaping and are able to obtain THz wave radiation of Gaussian or arbitrary transverse distribution. The novel experimental approach proposed in this paper opens up the research field of direct THz wave shaping using plasma. Moreover, it innovates multi-parameter convergence algorithms and, by doing so, has the potential to find beam patterns with higher energy conversion efficiency and break the energy limit of THz waves emitted by lasers at high power.
Simulation of optical and electrical synaptic functions in MoS_2/α-In_2Se_3 heterojunction memtransistors

Memtransistors combine memristors and field-effect transistors, which can introduce multi-port control and have significant applications for enriching storage methods. In this paper, multilayer α-In_2Se_3 and MoS_2 were transferred to the substrate by the mechanical exfoliation method, then a heterojunction MoS_2/α-In_2Se_3 memtransistor was prepared. Neural synaptic simulations were performed using electrical and optical pulses as input signals. Through measurements, such as excitatory/inhibitory post-synaptic current (EPSC/IPSC), long-term potentiation/depression (LTP/LTD), and paired-pulse facilitation/depression (PPF/PPD), it can be found that the fabricated device could simulate various functions of neural synapses well, and could work as an electronic synapse in artificial neural networks, proposing a possible solution for neuromorphic storage and computation.
Structure, magnetism and magnetocaloric effects in Er_5Si_3B_x (x = 0.3,0.6) compounds

We investigate the structure, magnetic properties, magnetic phase transitions and magnetocaloric effects (MCEs) of Er_5Si_3B_x (x = 0.3, 0.6) compounds. The Er_5Si_3B_x (x = 0.3, 0.6) compounds crystalize in a Mn5Si3 type hexagonal structure (space group: P63/cm) and exhibit a successive complicated magnetic phase transition. The extensive magnetic phase transitions contribute to the broad temperature range of MCEs exhibiting in Er_5Si_3B_x (x = 0.3, 0.6) compounds, with maximum magnetic entropy change (-∆S_M~(max)) and refrigeration capacity of 10.2 J·kg~(-1)·K~(-1), 356.3 J/kg and 11.5 J·kg~(-1)·K~(-1), 393.3 J/kg under varying magnetic fields 0-5 T, respectively. Remarkably, the dTFWHM values (the temperature range corresponding to 1/2 ×|-∆S_M~(max)|) of Er_5Si_3B_x (x = 0.3, 0.6) compounds were up to 41.8 K and 39.6 K, respectively. Thus, the present work provides a potential magnetic refrigeration material with a broad temperature range MCEs for applications in cryogenic magnetic refrigerators.
Eclogites and basement terrane tectonics in the northern arm of the Grenville orogen, NW Scotland

The presence of eclogites within continental crust is a key indicator of collisional orogenesis. Eclogites within the Eastern Glenelg basement inlier of the Northern Highland Terrane (NHT) have been redated in order to provide more accurate constraints on the timing of collision within the northern arm of the Grenville Orogen. The eclogites yield dates of ca. 1200 Ma which are interpreted to record the onset of continent-continent interaction, and the NHT as a whole is thought to represent the lower plate in successive 1200-1000 Ma collision events. The Eastern Glenelg basement inlier is viewed as a fragment of the leading edge of the NHT continental basement that was partially subducted along a suture and then exhumed back up the subduction channel. Differences in ages of igneous protoliths and intrusive histories, and metamorphic events (this paper) between the NHT basement and the Laurentian foreland, suggests that they were separate crustal blocks until after ca. 1600 Ma. We therefore suggest that: (1) the NHT represents a fragment of Archean-Paleoproterozoic crust that was reworked within the ca. 1.7-1.6 Ga Labradorian-Gothian belt, although whether it was derived from Laurentia or Baltica is uncertain, and (2) amalgamation of the NHT with the Laurentian foreland did not occur until the terminal stages of the Grenville collision at ca. 1000 Ma.
Fast adaptive regression-basedmodel predictive control

Model predictive control (MPC) is an optimal control method that predicts the future states of the system being controlled and estimates the optimal control inputs that drive the predicted states to the required reference. The computations of the MPC are performed at pre-determined sample instances over a finite time horizon. The number of sample instances and the horizon length determine the performance of the MPC and its computational cost. A long horizon with a large sample count allows the MPC to better estimate the inputs when the states have rapid changes over time, which results in better performance but at the expense of high computational cost. However, this long horizon is not always necessary, especially for slowly-varying states. In this case, a short horizon with less sample count is preferable as the same MPC performance can be obtained but at a fraction of the computational cost. In this paper,we propose an adaptive regression-based MPC that predicts the bestminimum horizon length and the sample count from several features extracted from the time-varying changes of the states. The proposed technique builds a synthetic dataset using the system model and utilizes the dataset to train a support vector regressor that performs the prediction. The proposed technique is experimentally compared with several state-of-the-art techniques on both linear and non-linear models. The proposed technique shows a superior reduction in computational time with a reduction of about 35-65% compared with the other techniques without introducing a noticeable loss in performance.
Design of a new static solar concentrator with a high concentration ratio and a large acceptance angle based on bifacial solar cells

Solar concentrators are used in solar photovoltaic systems to lower the cost of producing electricity.In this situation,fewer solar cells can be used,lowering the overall cost of the system.The purpose of this article is to design,construct,install and test a stationary (nontracking) concentrating system in Irbid,Jordan.Bifacial solar cells are used in the design.Two concentrator designs (with the same concentration ratio) are experimentally tested.Conc-A has a parabolic shape in the lower part but flat reflecting walls,whereas Conc-B has a standard compound parabolic shape in all parts.The receiving solar cells are arranged in three distinct positions in each concentrator.The results reveal that the output power from both concentrators is affected by the placement of the receiving solar cells within the concentrator.It has also been found that concentrators with flat reflecting walls perform better than those with parabolic reflecting walls.Conc-A's power collection is ~198% greater than that of a non-concentrating device.When Conc-B is used,the increase in power is ~181%.
乳腺多形性腺癌1例

本例患者肿瘤中的P53呈弥漫强阳性表达,说明p53基因发生了突变,与其他涎腺样乳腺癌不同; Ki-67增殖指数高,而大多数涎腺PAC增殖指数较低,说明相较于涎腺PAC,乳腺PAC增殖能力更强。分子水平上,涎腺PAC通常有PRKD1基因突变,可能为PAC的驱动因素,而乳腺PAC是否有PRKD1基因突变鲜有研究证实。乳腺PAC诊断主要依靠组织形态学特征及免疫组织化学法,需与乳腺腺样囊性癌、浸润性小叶癌鉴别。本例乳腺PAC的免疫组织化学法检测显示,肿瘤中的E-cadherin阳性、P120细胞膜阳性,ER、PR均阴性,与乳腺浸润小叶癌中的E-cadherin阴性、P120细胞浆阳性、ER、PR阳性不同。与乳腺腺样囊性癌相比,乳腺PAC缺乏由导管上皮和肌上皮构成的典型双相型结构,仅由单一肿瘤细胞构成,必须经相关检查排除来源于涎腺癌的转移。乳腺PAC尚无特异性治疗方法,一般采取手术后放化疗,预后尚可。但本例患者的肿瘤具有Ki-67增殖指数高、P53弥漫阳性、核分裂像易见及大片坏死等特征,提示乳腺PAC预后不佳,且有研究发现患者短期内发生癌细胞转移而死亡。总之,对乳腺PAC加深认识及进一步探明肿瘤分子改变,有利于诊断和治疗。
Dual-Emission Carbonized Polymer Dots Combined with Metal Ions as a Single-Component Fluorescence Sensor Array for Pattern Recognition of Glycosaminoglycans

Herein,a novel dual-emission fluorescence sensor array of carbonized polymer dots (CPDs)-Cu~(2+) has been proposed,in which CPDs were prepared by one-pot hydrothermal method and Cu~(2+) acting as a quencher was combined with CPDs by electrostatic interaction.Four negatively charged glycosaminoglycans (GAGs) bearing different hydrophilic groups showed variable binding affinities towards CPDs-Cu~(2+).Upon reacting with these GAGs,the different fluorescence response signals of CPDs-Cu~(2+) can be further differentiated by principal component analysis (PCA).The CPDs-Cu~(2+) sensor array,not only allows the identification of four similarly structured GAGs,but also realizes the discrimination of different concentrations of the same GAGs and their mixtures.Remarkably,the identification of GAGs in biological fluids can also be achieved using our proposed single-component sensor array,validating its application potential.This new strategy avoids multiple sensing probes,broadens the application of tongue-mimic sensor arrays and provides a viable idea for the development of single component sensing platforms.
Research progress on corrosion behaviors and biocompatibility of rare-earth magnesium alloys in vivo and in vitro

As yet, Mg alloys acting as the medical implants have drawn extensive attention, due to their spontaneous degradability, effective load-transmissibility and the excellent biocompatibility, particularly in bone tissue reconstruction and vascular radial-support. Regrettably, they were inevitably affected by the tension/compression-torsion, dynamic erosion and corrosion fatigue under complex service conditions, which lead to premature failure of implantation-materials. Micro-alloying addition is an effective way to delay the rapid degradation, especially in rare-earth micro-composite addition. It can not only reduce intensities of galvanic-corrosion by refining the grain sizes and adjusting the Volta-potentials distribution of the precipitates, but also modify the compositions and biocompatibility of the degradation products. Moreover, the higher compress tress on the surface can improve the stability and densification of the film layer, which enhanced the corrosion resistance. Thus, the latest research progress about in vivo/vitro degradation behaviors and biocompatibility of rare-earth Mg alloys is reviewed; The internal relationships between rare-earth elements, phase features and degradation behaviors of Mg alloys are summarized. Moreover, the effects of rare-earth addition on the film-characteristics are deeply explained, and the induced mechanisms of rare earth elements on the biocompatibility are revealed.
Agglomeration behavior of rare earth inclusions and alumina inclusions at the interface between argon and molten steel

Nozzle clogging frequently occurs in steel containing rare earth (RE) due to the aggregation of RE inclusions, which seriously interferes with the application of RE in steel. To provide insights into nozzle clogging, the agglomeration behavior of inclusions in RE-containing steel was investigated by laboratory experiments and theoretical calculations. High-temperature confocal laser scanning microscopy (HTCLSM) was applied to observe the behavior of inclusions at molten steel surfaces and their interactive forces. KralchevskyePaunov (KeP) model was used to predict the capillary force acting on different inclusions. The results show that the interactive forces that acted on inclusions were investigated as a function of inclusion size, inter-distance, and inclusion composition. It is found that the capillary force acting on the inclusions decreases in the order of Ce_2O_3 > CeAlO3 > Al_2O_3. This study verified the applicability of the KeP model in RE-containing steel, which can provide theoretical support to help solve the nozzle clogging problem during rare earth steel production.
Single-Layer Symmetrical Full-Port Quasi-Absorptive Filtering Phase Shifter

In this article, a single-layer symmetrical full-port quasi-absorptive filtering phase shifter is presented. The proposed phase shifter is composed of a main quasi-absorptive filtering branch, a reference quasi-absorptive filtering branch, and two delay lines. The proposed phase shifter achieves both phase controlling function and quasi-absorptive filtering function for the first time. Each quasi-absorptive filtering branch can realize the quasi-absorptive filtering function. Meanwhile, the constant phase shift can be obtained by combining the two quasi-absorptive filtering branches and the two delay lines. The design formulas can be derived from the even- and odd-mode network analysis, and then two quasi-absorptive filtering phase shifters can be devised easily and quickly. For verification, a 90° quasi-absorptive filtering phase shifter, which is critical for circularly polarized antenna systems, is simulated, manufactured, and measured.
