Seasonal Variation in Air Temperature and Relative Humidity on Building Areas and in Green Spaces in Beijing, China

The cooling and humidifying effects of urban parks are an essential component of city ecosystems in terms of regulating microclimates or mitigating urban heat islands (UHIs). Air temperature and relative humidity are two main factors of thermal environmental comfort and have a critical impact on the urban environmental quality of human settlements. We measured the 2-m height air temperature and relative humidity at the Beijing Olympic Park and a nearby building roof for more than 1 year to elucidate seasonal variations in air temperature and relative humidity, as well as to investigate the outdoor thermal comfort. The results showed that the lawn of the park could, on average, reduce the air temperature by (0.80±0.19)℃, and increase the relative humidity by (5.24±2.91)% relative to the values measured at the building roof during daytime. During the nighttime, the lawn of the park reduced the air temperature by (2.64±0.64)℃ and increased the relative humidity by (10.77±5.20)%. The park was cooler and more humid than surrounding building area, especially in night period (more pronounced cooling with 1.84 ℃). Additionally, the lawn of the park could improve outdoor thermal comfort through its cooling and humidifying effects. The level of thermal comfort in the park was higher than that around the building roof for a total of 11 days annually in which it was above one or more thermal comfort levels (average reduced human comfort index of 0.92) except during the winter.
Cotton-derived oxygen/sulfur co-doped hard carbon as advanced anode material for potassium-ion batteries

Hard carbon is regarded as promising anode materials for potassium-ion batteries (KIBs) owing to their low price and easy availability. However, the limited rate capability still needs to be improved. Herein, we demonstrate the fabrication of oxygen/sulfur co-doped hard carbon through a facile hydrolyzation-sulfuration process of skimmed cotton. The simultaneous dopants significantly improve potassium ion diffusion rate. When served as the anode for KIBs, this hydrolyzed hard carbon delivered a high reversible capacity (409 mAh/g at 0.1 A/g), superior rate capability (135 mAh/g at 2 A/g) and excellent cyclability (about 120 mAh/g overt 500 cycles at 2 A/g). This work provides a facile strategy to prepare low-cost doped-hard carbon with superior potassium storage property.
Dual functional AgNPs-M13 phage composite serves as antibacterial film and sensing probe for monitoring the corrosion of chromium-containing dental alloys

The preparation of silver nanoparticles (AgNPs) with microbe or plant tissues as bio-template offers green approach, while it suffers from low harvest and purification is needed. Herein, we propose a facile protocol for one-pot preparation of AgNPs using M13 phage as bio-template by simply mixing AgNO_3 solution with alkali M13 phage. In the obtained AgNPs-M13 phage composite, Cr(III) selectively coordinates with the amino residues on phage surface and leads to the aggregation of AgNPs through the bridging of M13 phages. This makes it feasible for colorimetric sensing of Cr(III) by measuring the absorbance ratio of AgNPs at 600 and 405 nm, which provides a LOD of 14 nmol/L. The composite also showed favorable bactericidal activity for both Gram-positive and Gram-negative bacteria, making it a promising candidate as antibacterial film in chromium-containing dental alloys and meanwhile serve as a sensing probe for monitoring the corrosion of the dental alloys.
A novel Mo-based oxide β-SnMoO_4 as anode for lithium ion battery

Recently, the development of new electrode materials for lithium-ion batteries (LIBs) has received intensive attention. As an important family of inorganic materials, mixed Mo-based transition metal oxides system is focused as anode materials. In the present work, a simple route has been adopted for the synthesis of layered-flake-like β-SnMoO_4 Nano-assemblies, which have been explored as potential anode materials for the first time in lithium-ion battery (LIB). Overall, the current reports on metal molybdate as anode materials are still rarely. As the anode material for LIBs, it was observed that the fabricated anode is capable of delivering a steady state capacity of almost 400 mAh/g up to 300 cycles under the influence of 200 mA/g current density. Further, the anode material is suitable for use as a rated capacity anode because of its high current density tolerance. The present study can be further extended for the generation of a wide variety of other novel materials for multidisciplinary energy related applications.
Synthesis of two A-B-C type conjugated amphiphilic triblock fullerene derivatives and their application in organic solar cells

Two A-B-C type conjugated amphiphilic triblock fullerene derivatives C_(60)-2HMTPB and C_(60)-2EHTPB were obtained in multi steps synthesis with three different blocks, and the amphiphilic diblock molecular C_(60)-4TPB was also preferred as a reference. When as modifying layer on zinc oxide (ZnO), the three fullerene derivatives can all reduce the work function of ZnO via modulation of the interfacial dipoles and lead a better electrical coupling. As introducing treatment of toluene, the obvious self-assembly of fullerene derivatives were observed, which were supported by X-ray diffraction and contact angle of water measurement. Base on PTB7-Th:PC_(71)BM system, the inverted organic solar cells devices with structure of ITO/ZnO/fullerene derivatives/PTB7-Th: PC_(71)BM/M0O_3/AI got power conversion efficiencies of 8.62%, 8.83% and 9.00% for C_(60)-4TPB, C_(60)-2HMTPB and C_(60)-2EHTPB, respectively, compared 8.13% of devices with bare ZnO. The result of conjugated amphiphilic triblock fullerene derivatives provides a straightforward approaching by simultaneously modulating the morphology and interfacial work function of ZnO, which can also lead high performance in optoelectronic devices.

Multi-scale analysis of the spatial structure of China’s major function zoning

The spatial structures of China’s Major Function Zoning are important constraining indicators in all types of spatial planning and key parameters for accurately downscaling major functions. Taking the proportion of urbanization zones, agricultural development zones and ecological security zones as the basic parameter, this paper explores the spatial structures of major function zoning at different scales using spatial statistics, spatial modeling and landscape metrics methods. The results show: First, major function zones have spatial gradient structures, which are prominently represented by latitudinal and longitudinal gradients, a coastal distance gradient, and an eastern-central-western gradient. Second, the pole-axis system structure and core-periphery structure exist at provincial scales. The general principle of the pole-axis structure is that as one moves along the distance axis, the proportion of urbanization zones decreases and the proportion of ecological security zones increases. This also means that the proportion of different function zones has a ring-shaped spatial differentiation principle with distance from the core. Third, there is a spatial mosaic structure at the city and county scale. This spatial mosaic structure has features of both spatial heterogeneity, such as agglomeration and dispersion, as well as of mutual, adjacent topological correlation and spatial proximity. The results of this study contribute to scientific knowledge on major function zones and the principles of spatial organization, and it acts as an important reference for China’s integrated geographical zoning.
Impacts of climate change and LULC change on runoff in the Jinsha River Basin

The climate change and Land Use/Land Cover (LULC) change both have an important impact on the rainfall-runoff processes. How to quantitatively distinguish and predict the impacts of the above two factors has been a hot spot and frontier issue in the field of hydrology and water resources. In this research, the SWAT (Soil and Water Assessment Tool) model was established for the Jinsha River Basin, and the method of scenarios simulation was used to study the runoff response to climate change and LULC change. Furthermore, the climate variables exported from 7 typical General Circulation Models (GCMs) under RCP4.5 and RCP8.5 emission scenarios were bias corrected and input into the SWAT model to predict runoff in 2017–2050. Results showed that: (1) During the past 57 years, the annual average precipitation and temperature in the Jinsha River Basin both increased significantly while the rising trend of runoff was far from obvious. (2) Compared with the significant increase of temperature in the Jinsha River Basin, the LULC change was very small. (3) During the historical period, the LULC change had little effect on the hydrological processes in the basin, and climate change was one of the main factors affecting runoff. (4) In the context of global climate change, the precipitation, temperature and runoff in the Jinsha River Basin will rise in 2017–2050 compared with the historical period. This study provides significant references to the planning and management of large-scale hydroelectric bases at the source of the Yangtze River.

Computationally Efficient Direction of Arrival Estimation for Improved Nested Linear Array

Nested linear array enables to enhance localization resolution and achieve under-determined direction of arrival(DOA)estimation. In this paper,the traditional two-level nested linear array is improved to achieve more degrees of freedom(DOFs)and better angle estimation performance. Furthermore,a computationally efficient DOA estimation algorithm is proposed. The discrete Fourier transform(DFT) method is utilized to obtain coarse DOA estimates,and subsequently,fine DOA estimates are achieved by spatial smoothing multiple signals classification(SS -MUSIC)algorithm. Compared to SS-MUSIC algorithm,the proposed algorithm has the same estimation accuracy with lower computational complexity because the coarse DOA estimates enable to shrink the range of angle spectral search. In addition,the estimation of the number of signals is not required in advance by DFT method. Extensive simulation results testify the effectiveness of the proposed algorithm.
Numerical Simulation on Intergranular Microcracks in Interconnect Lines Due to Surface Diffusion Induced by Stress-, Electro- and Thermo-migration

Based on the weak formulation for combined surface diffusion and evaporation -condensation,a governing equation of the finite element is derived for simulating the evolution of intergranular microcracks in copper interconnects induced simultaneously by stressmigration,electromigration and thermomigration. Unlike previously published works,the effect of thermomigration is considered. The results show that thermomigration can contribute to the microcrack splitting and accelerate the drifting process along the direction of the electric field. The evolution of the intergranular microcracks depends on the mechanical stress field,the temperature gradient field,the electric field,the initial aspect ratio and the linewidth. And there exists a critical electric field ${\chi _{\rm{c}}}$,a critical stress field ${\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\frown$}} \over \sigma } _{\rm{c}}}$,a critical aspect ratio ${\beta _{\rm{c}}}$ and a critical linewidth ${\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\frown$}} \over h} _{\rm{c}}}$. When $\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\frown$}} \over \sigma } \ge {{\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\frown$}} \over \sigma } }_{\rm{c}}},\chi \ge {\chi _{\rm{c}}},\beta \ge {\beta _{\rm{c}}}$ or $\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\frown$}} \over h} \ge {{\mathord{\buildrel{\lower3pt\hbox{$\scriptscriptstyle\frown$}} \over h} }_{\rm{c}}}$,the intergranular microcrack will split into two or three small intergranular microcracks. Otherwise,the microcrack will evolve into a stable shape as it migrates along the interconnect line. The critical stress field,the critical electric field and the critical aspect ratio decrease with a decrease in the linewidth,and the critical linewidth increases with an increase in the electric field and the aspect ratio. The increase of the stress field,the electric field or the aspect ratio and the decrease of the linewidth are not only beneficial for the intergranular microcrack to split but also accelerate the microcrack splitting process.
Bandgap energy determination of InAsSb epilayers grown by molecular beam epitaxy on GaAs substrates

InAsSb ternary alloys can be considered as an alternative to HgCdTe for mid-wavelength, as well as long-wavelength infrared applications. Its energy bandgap exhibits nonlinearity versus Sb composition, and hence the correct determination of its value is necessary for the effective design and simulation of optoelectronic devices. The commonly used expression on the InAsSb energy bandgap provided by Wieder and Clawson overestimated energy bandgap values at high temperatures. In this paper, we present two modified empirical relationships which are based on the experimental data obtained in our laboratory and published literature. Both are correct for a wide range of Sb molar composition and temperatures. The nonlinearity of the energy gap is described with the adequate bowing parameter. The data collected in our experiment, for samples grown on lattice mismatched GaAs substrates, fits well with a bowing factor of C=0.72 eV. The minimum bandgap energy that can be reached at room temperature is about 73 meV for a Sb mole fraction, x=0.63. In comparison, the bandgap at low temperatures collected in the literature for samples grown on lattice-matched GaSb substrates is smaller than the measured values in our experiment and fits well with a parabola with C=0.9 eV.

LncRNA MIR4435-2HG is a potential early diagnostic marker for ovarian carcinoma

LncRNA MIR4435-2HG is characterized as an oncogene in lung cancer. However, its role in ovarian carcinoma(OC)is unclear. In this study,we aimed to investigate the role of MIR4435-2HG in OC.We found that both MIR4435-2HG and transforming growth factor beta 1(TGF-β1)were upregulated in OC. MIR4435-2HG is associated with tumor metastasis but not with tumor size. Upregulation of MIR4435-2HG distinguished early stage(Stage I and II)OC patients from healthy controls. Correlation analysis showed that plasma levels of MIR4435-2HG and TGF-β1 were positively correlated only in OC patients. qPCR and western blot analysis results showed that MIR4435- 2HG overexpression led to upregulation of TGF-β1 in OC cells, while TGF-β1 treatment did not significantly affect MIR4435-2HG expression. Transwell invasion and migration assays showed that MIR4435-2HG and TGF-β1 promoted the invasion and migration of OC cells while TGF-β inhibitor suppressed the invasion and migration of these cells. Further analysis of the Transwell invasion and migration assay results showed that TGF-β inhibitor reduced the effects of MIR4435-2HG overexpression. Therefore, our results suggested that lncRNA MIR4435-2HG may promote OC by upregulating TGF-β1. Further characterization of the functions of MIR4435-2HG in OC may provide novel targets for cancer therapies.
Mechanical and dielectric properties of porous and wave-transparent Si_3N_4-Si_3N_4 composite ceramics fabricated by 3D printing combined with chemical vapor infiltration

Porous Si_3N_4-Si_3N_4 composite ceramics were fabricated by 3D printing combined with low-pressure chemical vapor infiltration (CVI).This technique could effectively improve the designability of porous Si_3N_4 ceramics and optimize the mechanical and dielectric properties.The effects of process parameters including the deposition time and heat treatment on the microstructure and properties of porous Si_3N_4-Si_3N_4 composite ceramics were studied.The study highlights following:When CVI processing time was increased from 0 to 12 h,the porosity decreased from 68.65% to 26.07% and the density increased from 0.99 to 2.02 g/cm~3.At the same time,the dielectric constant gradually increased from 1.72 to 3.60;however,the dielectric loss always remained less than 0.01,indicating the excellent electromagnetic (EM) wave-transparent performance of porous Si_3N_4-Si_3N_4 composite ceramics.The maximum flexural strength of 47±2 MPa was achieved when the deposition time attained 6 h.After heat treatment,the porosity increased from 26.07% to 36.02% and the dielectric constant got a slight increase from 3.60 to 3.70 with the dielectric loss still maintaining lower than 0.01.It has been demonstrated that the porous Si_3N_4-Si_3N_4 composite ceramics are a promising structural and EM wave-transparent material suitable for high temperature service.
Prediction of electrical contact endurance subject to micro-slip wear using friction energy dissipation approach

Fretting wear is a common cause of failure of an electrical contact (EC).In this study,we analyzed in detail the failure of EC induced especially by sliding using the representative electrical terminals.Furthermore,combining the friction energy dissipation theory,we proposed a prediction model to evaluate the electrical connector endurance (ECE) based on the contact stress and geometrical changes during the wear process obtained from a numerical model.The study helps establish that the friction energy dissipation theory is a powerful tool to analyze a contact failure due to wear.The proposed model proves to be effective in predicting the ECE for all considered cases such as micro-slip amplitude,contact force,overturning angle,superficial layer thickness,and friction/wear coefficients.
Fast raycasting using a compound deep image for virtual point light range determination

The concept of using multiple deep images, under a variety of different names, has been explored as a possible acceleration approach for finding raygeometry intersections. We leverage recent advances in deep image processing from order independent transparency for fast building of a compound deep image (CDI )using a coherent memory format well suited for raycasting. We explore the use of a CDI and raycasting for the problem of determining distance between virtual point lights (VPLs)and geometry for indirect lighting, with the key raycasting step being a small fraction of total frametime.
Rapid breeding of pink-fruited tomato hybrids using the CRISPR/Cas9 system

As one of the most important vegetables, tomato (Solanum lycopersicum) is extensively produced and consumed worldwide and substantially contributes to human nutrition and health (The Tomato Genome Consortium, 2012). Although red tomatoes are the most common, pink tomatoes are more popular in Asia, particularly in China and Japan, because of their better taste (Ballester et al., 2010; Zhu et al., 2018). Compared with red tomatoes, pink tomatoes fail to accumulate the yellow-colored flavonoid pigment, naringenin chalcone (NarCh), in their peels, resulting in a colorless peel phenotype (Adato et al., 2009; Ballester et al., 2010). Genetic studies have demonstrated that this colorless peel trait results from loss-of-function in MYB12, a master transcription factor regulating flavonoid biosynthesis (Adato et al., 2009; Ballester et al., 2010). To date, five null alleles of MYB12 have been identified and used for pink-fruited tomato breeding by the advanced backcross strategy (Fernandez-Moreno et al., 2016).
Generalized LMMSE Filtering with Out-of-Sequence Observations in Arbitrary Constant Delay

Focusing on the problem of state estimation in the presence of sensor faults and Out-of-sequence measurement (OOSM) observations synchronously, we derive a formulation of Linear minimum mean squared error (LMMSE) filter with the arbitrary time delay of OOSM, the generalization of the present work lies in simultaneous treatment of correlated faults together with OOSMs that arrive at an arbitrary delay in a linear-optimal manner. The approach is demonstrated in a numerical comparison.
Quantum Codes from Constacyclic Codes over Polynomial Residue Rings

Sufficient and necessary conditions for Hermitian (1+λu)-constacyclic self-orthogonal codes over Fpm+uFpm are obtained, where λ is a unit of Fpm+uFpm. Based on this, a new method for the construction of pm- ary quantum codes from the obtained Hermitian (1+λu)- constacyclic self-orthogonal codes over Fpm+uFpm is given. As an example, [[pm - 1; pm - 2d+1; d]]pm quantum MDS codes are constructed for 1 ≤ d ≤ (pm+1)/2 and p ̸= 2, as well as some other quantum codes.
A Robust on-Wafer Large Signal Transistor Characterization Method at mm-Wave Frequency

Accurate on-wafer large signal characterization of RF transistor is crucial for the optimum design of wireless communication circuits. We report a novel and systematic measurement method for the accurate acquisition of input and output power of on-wafer transistors up to 40GHz. This method employs external couplers to extract the travelling waves, combined with a novel large signal calibration algorithm to calculate the power at on-wafer probe tip. The accuracy of this method was bench marked versus conventional approaches in a real measurement bench, and further been verified by characterizing the large signal response of a 0.25µm GaN HEMT device. It is concluded that the measurement uncertainty has been greatly decreased with this new method, especially at mm-wave frequencies.
CNN Based Classification of Rigid Targets in Space Using Radar Micro-Doppler Signatures

Micro-motion characteristics play an important role in some applications of radar target classification. In this paper, a classification method of rigid targets in space using radar micro-Doppler signatures is proposed. Based on the attitude kinematics of rigid targets, we analyze feasibility of classification using micro-Doppler signatures by the relationship among inertial properties of typical rigid targets, their micro-motion characteristics, and corresponding modulation to radar echoes. According to the micro-Doppler time-frequency distribution of echoes and the scale of training sample set, Convolutional neural network (CNN) based feature extraction method and softmax Classifier are designed. Simulations are carried out to validate its effectiveness and discuss the impact of observation duration, composition of training data and size of convolutional kernels on its classification robustness and computational cost.
