Authors: Sun Ran , Zhao Yuyang , Wang Yanan , Zhang Qian , Zhao Ping 
Published: February 2021

Abstract
Dual-modal molecular imaging that combines photoacoustic imaging with near-infrared fluorescence imaging integrates the benefits of both imaging modalities and may achieve more precise detection of disease. In this study, silver sulfide quantum dots (Ag2S QDs) with superior photoacoustic properties and a strong fluorescent emission in the NIR region were successfully synthesized. They were further modified with the insulin-like growth factor 1 receptor (IGF-1R) targeted small scaffold protein, Affibody (ZIGF-1) to achieved targeted photoacoustic/fluorescent dual-modal imaging of cancer. Our results showed that the prepared nanoprobe had good tumor targeting properties in vivo, and the probe also showed good biocompatibility without any significant toxicity.

Published: February 2021

Abstract
A bendable and thermally stable solar-blind ultraviolet (UV) photodetector has been demonstrated based on Ni/amorphous Ga2O3 (a-Ga2O3)/a-AlN/Cu foil structure. Here, Cu foil can simultaneously act as a bendable substrate and withstand a high-temperature environment. The ultra-wide bandgap a-AlN insulating layer can withstand mechanical tensile stress and effectively act as an insulating layer between a-Ga2O3 and Cu. Thus, the a-Ga2O3-based photodetector shows stable UV response characteristics with different bending radii and temperatures. The photodetector has high responsivity of 0.518 A W−1 and a fast response time of 0.17 s under 200 °C temperature with a 1.46 cm bending radius. With exceptional bendability and thermal stability, this a-Ga2O3-based photodetector has potential applications in harsh environments such as high-power bendable electron devices, flame detection, etc.

Terahertz radiation enhancement based on LT-GaAs by optimized plasmonic nanostructure
Authors: Jiang Rui , Cheng Shuang , Li Quanyong , Wang Qishu , Xin Yinjie 
Published: February 2021

Abstract
Terahertz waves have unique penetrability, safety, spectral resolution, and many other useful properties. Therefore, terahertz waves are widely employed in medical treatment, detection, imaging, security, and spectroscopy. They also possess great development prospects in photoconductive antennas (PCAs) for telecommunication and other devices. However, terahertz PCAs are still limited by the weak photocurrents and small light absorption rates, making the development of PCAs with improved conversion efficiencies highly desirable. In this study, a new type of plasmonic PCAs with high photoelectric conversion efficiency was proposed. The interaction between the 800 nm fs laser and staggered nanorods was studied by the finite difference time domain (FDTD) method. The geometric parameters of the nanorods arrays were optimized. Compared to conventional photoconductive antennas without nanostructures, the PCAs with optimized nano-plasmonic structure I showed threefold higher electric field radiations under 800 nm fs laser irradiation. Optimized plasmonic nanostructure II increases photocurrent up to 335.553 nA that indicates 10 times enhancement in comparison with conventional structure. Hence, the developed structures greatly enhanced the light absorption of the photosensitive layer based on low-temperature-grown gallium arsenide. In sum, the proposed staggered hexagonal plasmonic structures (structure II) could effectively improve the light-terahertz conversion efficiencies of PCAs.

Authors: Yuan Weirong , Sizyuk Tatyana 
Published: February 2021

Abstract
The interactions of femtosecond lasers with gold targets are investigated with a numerical method combining molecular dynamics and two-temperature model and temperature dependent thermodynamic parameters. The influence of the electron temperature dependent (ETD) interatomic potential on ablation processes was analyzed. We also adopted an ETD electron–phonon coupling factor and further analyzed different ablation mechanisms under absorbed fluences ranging from

Our simulation results showed good agreements on melting and ablation depth with both experiments and other simulations. Three ablation mechanisms were identified: nonthermal ablation caused by electronic pressure from the ETD interatomic potential, spallation by stresses from a rapid heating of the target and phase explosion due to explosive boiling. With a continuously updated ETD potential in accordance with electron temperature, one can explain the unique U shape profile of plume atomization degree as a function of laser fluence found in experiments.
Fast dissipative preparation of three-dimensional entangled states for two Rydberg atoms via Lyapunov control
Authors: Ding Zong-Xing , Hu Chang-Sheng , Shen Li-Tuo , Su Wan-Jun , Wu Huaizhi , Zheng Shi-Biao 
Published: February 2021

Abstract
By using the Lyapunov control approach—an optimization algorithm, we propose a dissipative scheme for efficiently preparing the three-dimensional entangled state of two Rydberg atoms, which subject to Rydberg–Rydberg interactions at the antiblockade regime. The steady target state is the unique dark state of the two-atom system, and is achieved with high fidelity under the Rydberg pumping and the atomic spontaneous emission. The time required to settle into the high-fidelity steady state is greatly accelerated by the help of Lyapunov control, which takes effects while the system is initially prepared in the states containing coherence between the dark state and decoherence-sensitive bright states. The numerical results show that a fidelity of the steady three-dimensional entangled state above 0.99 can be achieved around 2.2 ms with the current experimental conditions. We study in detail the optimal control parameters and show the robustness of the scheme against random noises. The scheme may be generalized for preparation of more complicate multi-atom entangled states.

Published: February 2021

Abstract
Based on the idea of knowledge distillation, a teacher-student ensemble method is proposed for UCFD (Unburned Carbon in Flue Dust) prediction when influencing factors have different sampling frequency. First, a multi-layer feed forward network is built as the teacher model. Loss function is customized to account for the sampling period discrepancy between outputs and inputs. With this teacher model, UCFD could have the same rate with its influencing factors. Second, Xgboost and Adaboost are used to form an ensemble student model to improve the training process and prediction robustness. Third, a power plant in Shandong province is chosen to make data experiment. Results illustrate that the teacher-student ensemble method can give a more accurate forecast.

Published: February 2021

Abstract
According to the characteristics and development trend of microgrid, instead of being the pure load, demand-side is treated as a kind of possible power supply (equivalent effect of reduction of the load) which can actively participate in the planning and operation in microgrid. An integrated resources planning model considering direct load control (one of demand responses) in microgrid was proposed. The validity of the proposed model was proved. It can be achieved to minimize the total cost of system planning by using demand response to actively participate in the planning. Depth discussions for the case were done to give comparative analysis of different control strategies, parameters and costs and more planning proposals were given.

Authors: Feng Junshu , Jiao Bingqi , Zhao Jiujin 
Published: February 2021

Abstract
Recently, with the adjustment of industrial structure, peak power load is getting sharper in China. Interruptible Load Management (ILM) enables power system to gain deterministic access to Interruptible Load (IL) provided by power consumers, which can use a more economical way to ensure real-time balance and safe operation of power system. This paper proposes a simulation method of interruptible load supply curve of lager industrial power consumers based on industrial classification, which can predict capacity of interruptible load that lager industrial power consumers are willing to provide under different interruptible load prices. An example towards a China’s eastern province shows that, if government wants to acquire interruptible load capacity of 10 million kW, the interruptible price should be priced higher than 0.7 RMB/kWh.

Published: February 2021

Abstract
In view of the serious deformation of roadway 2220 in Majiliang Coal Mine after excavation, the surrounding rock deformation characteristics and stress redistribution of the roadway are studied and analyzed by numerical simulation technology, and the support optimization is carried out. The research results show that the original support scheme can not effectively reduce the roadway deformation and the area of plastic zone and stress concentration area after roadway excavation. After the optimization of the support scheme, the shape variables of the roof and floor and the two sides are obviously reduced, and the plastic zone and stress concentration area are also greatly reduced, which significantly improves the overall stability of the roadway.

Authors: Aiello Donatella 
Published: February 2021

Abstract
Saffron is one of the oldest natural dyestuffs and is obtained from the dried stigmata of Crocus sativus L. The yellowness of saffron results from the presence of crocins (glycosyl esters of crocetin). In this report we present the identification and characterization of multiple forms of crocins from whole saline saffron extracts using direct MALDI MS and MS/MS of glycosyl esters of crocetin and of their corresponding Hydrazine tagged products.

Identification and isolation of homoserine lactones (HSLs) produced by Pseudomonas aeruginosa and the effects on Legionella pneumophila growth
Authors: Materazzi S. , De Giusti M. , Marinelli L. 
Published: February 2021

Abstract
Risk for infections from Legionella pneumophila represents a critical issue for immunocompromised individuals, especially when this species is present within the biofilm of the water distribution systems of hospitals or other health facilities where the complex ancient water network creates environmental conditions that are suitable for Legionella persistence and multiplication. The shock hyperchlorination and subsequent systemic continuous chlorination is a disinfection treatment reported in the Italian Guideline for prevention and control of nosocomial legionellosis as an effective procedure to reduce L. pneumophila colonization of hospital water sources. Although this disinfection strategy has been proven to be effective in the short-term, eradication of Legionella from water networks is usually not achieved. The objective of this study is the identification and purification of P. aeruginosa bacteriocins, such as homoserine lactones (HSLs), by the development of an experimental method by High performance-liquid chromatography (HPLC), coupled to diode array detection (DAD) and the evaluation of the effectiveness of these molecules in the managing of the persistence of L. pneumophila in experimental cocultures.
A novel, structurally coloured coating for aluminium alloys
Authors: Mardon Ian J , Hou Fengyan , Goode Chris 
Published: February 2021

Abstract
Current approaches to coat aluminium surfaces that use paints and organic coatings to protect them from corrosion and provide an aesthetic finish, are also energy intensive and involve high emissions of VOCs. The use of these coatings is becoming increasingly restricted by global efforts towards more environmentally sustainable surface finishing technologies. A recent development based on porous anodised aluminium (PAA) and metal nanowire deposits is presented here, which may become a competitive alternative to paint and organic coatings. Anodising and electrodeposition do not emit VOCs and are less energy intensive. By controlling the conditions for anodising and metal electrodeposition, coatings in a wide spectrum of colours can be produced, including greys, black, blues, purples, and greens. Characterisation of the coating morphologies and corresponding colours agrees with simulated results based on the Fresnel equations and Bruggeman Mixed Media Approximations.
Effects of the Carbon Fiber Orientations for the Strengthening of Thin-Walled Steel Cylinders under Compressive Loads and Bending Shear Loads
Authors: Nhut P V , Matsumoto Y , Matsui T , Nakamura H 
Published: February 2021

Abstract
In this study, the effects of carbon fiber orientations on the strengthening of small-scale thin-walled steel cylinders (TSCs) under axial compression were experimentally and numerically investigated. Besides, the strengthening effects of various types of carbon fiber reinforced polymers (CFRPs) on the load-carrying capacity of full-scale TSCs were numerically investigated. The results showed that circumferential CFRP layers (0°) have significant effects on the increased load-carrying capacity of TSCs under axial compression, whereas, only 90° CFRP layers had small strengthening effects for TSCs under axial compression. When the TSCs subjected to bending shear loads with high values of internal pressures, the appearances of circumferential fibers also brought better strengthening effects than only the angled fibers for TSCs.
2DEG and 2DHG in NaTaO3 polar thin films: thickness and strain dependency
Authors: Portugal Guilherme Ribeiro , Teodoro Arantes Jeverson 
Published: February 2021

Abstract
Two-dimensional (2D) carrier gases in perovskite surfaces and interfaces have been intensely studied since their properties are attractive to many functional devices and applications. Here, we demonstrate through ab initio DFT calculations that surface 2D carries gases can be found in NaTaO3 ultrathin films. Furthermore, we show the thickness dependence of such phenomenon and how it can be tuned when biaxial in-plane strain is applied. Tensile does not alter the valence and conduction character of the films but promotes 2D electron and hole gases in the (TaO2)+ and (NaO)− surfaces, respectively. Because of the competition between surface and strain effects to deal with the cleavage-induced polarity, biaxial compression is able to generate 2D hole gases in the (TaO2)+ surface instead. Such carrier-type and layer switching are explained through changes in the electrostatic potential balancing along the [001] direction and (Na,Ta) cations displacements. The presented results concern not only nanoelectronics but also catalytic applications where modulating bandgap and valence/conduction states is desired.
Invited Commentary: Treatment Drop-in—Making the Case for Causal Prediction
Authors: Sperrin Matthew , Diaz-Ordaz Karla , Pajouheshnia Romin 
Published: February 2021

AbstractClinical prediction models (CPMs) are often used to guide treatment initiation, with individuals at high risk offered treatment. This implicitly assumes that the probability quoted from a CPM represents the risk to an individual of an adverse outcome in absence of treatment. However, for a CPM to correctly target this estimand requires careful causal thinking. One problem that needs to be overcome is treatment drop-in: where individuals in the development data commence treatment after the time of prediction but before the outcome occurs. In this issue of the Journal, Xu et al. (Am J Epidemiol. 2021;190(10):2000–2014) use causal estimates from external data sources, such as clinical trials, to adjust CPMs for treatment drop-in. This represents a pragmatic and promising approach to address this issue, and it illustrates the value of utilizing causal inference in prediction. Building causality into the prediction pipeline can also bring other benefits. These include the ability to make and compare hypothetical predictions under different interventions, to make CPMs more explainable and transparent, and to improve model generalizability. Enriching CPMs with causal inference therefore has the potential to add considerable value to the role of prediction in healthcare.
Brain Volumes in Mice are Smaller at Birth After Term or Preterm Cesarean Section Delivery

Published: February 2021

AbstractThe rate of cesarean section (CS) delivery has steadily increased over the past decades despite epidemiological studies reporting higher risks of neonatal morbidity and neurodevelopmental disorders. Yet, little is known about the immediate impact of CS birth on the brain, hence the need of experimental studies to evaluate brain parameters following this mode of delivery. Using the solvent clearing method iDISCO and 3D imaging technique, we report that on the day of birth, whole-brain, hippocampus, and striatum volumes are reduced in CS-delivered as compared to vaginally-born mice, with a stronger effect observed in preterm CS pups. These results stress the impact of CS delivery, at term or preterm, during parturition and at birth. In contrast, cellular activity and apoptosis are reduced in mice born by CS preterm but not term, suggesting that these early-life processes are only impacted by the combination of preterm birth and CS delivery.
