reliable detection of mutations below 0.5% variant allele frequency remains a key challenge for circulating tumor dNA sequencing assays. Circulating tumor dNA (ctdNA) sequencing is being rapidly adopted in precision oncology, but the accuracy, sensitivity and reproducibility of ctdNA assays is poorly understood. Here we report the findings of a multi-site, cross-platform evaluation of the analytical performance of five industry-leading ctdNA assays. We evaluated each stage of the ctdNA sequencing workflow with simulations, synthetic dNA spike-in experiments and proficiency testing on standardized, cell-line-derived reference samples. Above 0.5% variant allele frequency, ctdNA mutations were detected with high sensitivity, precision and reproducibility by all five assays, whereas, below this limit, detection became unreliable and varied widely between assays, especially when input material was limited. Missed mutations (false negatives) were more common than erroneous candidates (false positives), indicating that the reliable sampling of rare ctdNA fragments is the key challenge for ctdNA assays. This comprehensive evaluation of the analytical performance of ctdNA assays serves to inform best practice guidelines and provides a resource for precision oncology.

Hygroscopic dopant in hole transport layer (HTL) is a key factor contributing to moisture-induced perovskite degradation and the resulting performance loss over time. This poses obstacles to the commercialization of perovskite solar cells (PSCs). Herein, we mixed two popular hole transport materials, i.e., [2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenyl-amine)9,9′-spirobifluorene] (Spiro-OMeTAd) and poly (3-hexylthiophene-2,5-diyl) (P3HT), to form a binary mixed HTL. due to the presence of hydrophobic P3HT component, the mixed HTL exhibits improved moisture resistance. In addition, P3HT demonstrates a great ability to interact with the dopants, which changes π-π packing orientation of P3HT from edge-on to face-on and improves its crystallinity, thus increasing hole mobility and hole extraction capability of the mixed HTL. As a result, PSCs equipped with the Spiro-OMeTAd/P3HT mixed HTL exhibit a champion power conversion efficiency (PCE) up to 24.3% and superior operational stability. The cells without encapsulation can maintain 90% initial efficiency after storage in dark ambient conditions (30% rH) for 1200 h. These results suggest that constructing Spiro-OMeTAd/P3HT mixed HTL is a promising strategy to meet the future photovoltaic applications demands with low-cost as well as excellent efficiency and device stability.

Irradiation damage research is one of the basic issues to solve the application of first-wall materials in fusion engineering. The diffusion and recovery of the defects can greatly affect the performance of the materials in fusion. The rotation stability, complex migration processes and the uniaxial strain modulus M-[ijk] of the self-interstitial atoms (SIAs) in defect structures of tungsten were investigated by the first-principle method. It was found that the <11h>dumbbell had a lower formation energy than <111>dumbbell. Further confirmation has been done from the uniaxial strain that the uniaxial modulus M-[11h] has a minimum value of 518Gpa in crystal tungsten. It demonstrated that the stress field played an important role to the SIA dumbbells. Nevertheless, the calculation indicated that the <11 h> SIA would be the key subject in finishing the complex migration in evolution of irradiation defects. (C) 2017 Elsevier B.V.

Nonaqueous redox flow batteries (rFBs) have received significant research interest, but the lack of promising separators with advanced performance seriously hinders the development of nonaqueous rFBs. Here, a robust yet flexible membrane with enhanced selectivity for nonaqueous rFBs is designed via in situ synthesis of metal-organic frameworks (MOFs) in a porous polymeric membrane (Celgard) with a gradient density. The crossover of active species is mitigated by the reduced effective pore size while high ionic conductivity is maintained, which is attributed to the 3d channel structure of MOFs and their gradient distribution in the membrane. A Li/ferrocene rFB with the MOF-imbedded membrane delivers an excellent high-rate capability and enhanced cycling stability. The discharge capacity reaches as high as approximate to 94% of theoretical value at a current density of 4 mA cm(-2), and maintains 76% even at 12 mA cm(-2). Moreover, a much slower capacity decay rate is achieved (0.09% per cycle over 300 cycles) by using the composite membrane compared with the pristine Celgard membrane (0.24% per cycle). The demonstrated strategy provides new insight into rational design and fabrication of size-sieving separators for rFBs and can promote further research of MOFs' capability in energy storage.

IOP Conference Series: Earth and Environmental Science 2019年第6期267卷

Offshore oil-gas platforms in the same area are generally connected through the power grid and subsea oil-gas pipeline networks. It has formed a typical integrated energy system which interacts with multiple energy sources, water, electricity, gas and oil. However, the traditional energy management research mainly focuses on the stability control of the platform's power network, and does not model the energy system of the platform group as a whole, which cannot reflect the characteristics of energy interaction between the platform groups. Therefore, this paper combs the current situation of energy utilization and operation control of offshore oil-gas platform energy system in a sea area of China, establishes the energy network of offshore oil-gas platform group, and puts forward the modelling, analysis and optimization method of offshore oil platform group. Firstly, focusing on the main energy coupling equipment (gas power station, gas heat station, electric heater,) of the platform, the energy efficiency analysis model is established to realize the energy efficiency diagnosis of the equipment. Then, based on the theory of Energy Hub, an electro-gas interaction optimization scheduling method is proposed to realize the optimization analysis of energy interaction between platforms. Finally, a calculation example of the actual platform group is given, which consists of three power generation platforms in China. The relevant research results will guide the closed-loop management of the operation, optimization and evaluation of the energy system. The application in the integrated energy management system of offshore oil-gas platform is helpful to improve the energy integration control of offshore oil platform.

Circulating natural killer (NK) cells help protect the host from lympho-hematogenous acute viral diseases by rapidly entering draining lymph nodes (dLNs) to curb virus dissemination. Here, we identify a highly choreographed mechanism underlying this process. Using footpad infection with ectromelia virus, a pathogenic dNA virus of mice, we show that TLr9/Myd88 sensing induces NKG2d ligands in virus-infected, skin-derived migratory dendritic cells (mdCs) to induce production of IFN-gamma by classical NK cells and other types of group 1 innate lymphoid cells (ILCs) already in dLNs, via NKG2d. Uninfected inflammatory monocytes, also recruited to dLNs by mdCs in a TLr9/Myd88-dependent manner, respond to IFN-gamma by secreting CXCL9 for optimal CXCr3-dependent recruitment of circulating NK cells. This work unveils a TLr9/Myd88-dependent mechanism whereby in dLNs, three cell types-mdCs, group 1 ILCs (mostly NK cells), and inflammatory monocytes-coordinate the recruitment of protective circulating NK cells to dLNs.

In this study, a low-profile ultrahigh frequency (UHF) radio-frequency identification (rFId) tag antenna designed for wristbands in healthcare applications is proposed. The radiator is based on the open-slot cavity technique that is composed of a slotted patch (double-T slots) loaded onto a flexible open cavity. The proposed slotted design can easily allow the tag's input impedance to be tuned to the complex impedance of typical UHF rFId chips. The proposed tag antenna has a size of 86 mm x 25 mm x 1.6 mm (0.26 lambda(0) x 0.07 lambda(0) x 0.004 lambda(0)) at 915 MHz, and it can yield a maximum reading range of 8 m (stand alone in free-space condition), 6.6 m (when placed on the human wrist in free-space condition), and up to 3 m (when placed on the human wrist in a crowded condition).

Tungsten-based alloy would be one of the effective ways to solve the problem of irradiation damage to plasma-facing materials. 4d, 5d transition metal elements (re, Ta, Hf, Mo, Nb, Zr) have been choosen as W-based alloy to research the interaction relationship between transition elements and mono-vacancy in W lattice. The results of migration barrier energy (Em) demonstrated that transition metal would be beneficial to mono-vacancy diffusion, in which re, Hf, Mo, Zr alloy atoms had been proved an advantageous influence on forming mono-vacancy than Ta, Nb elements, and the minimal Em was about 0.859eV in W-Zr system. The volume of octahedral in the saddle point had proved the stress of the alloying atom was closely related with the Em of the vacancy. The effect of the alloying element concentration on mono-vacancy in W system presented an inverse relationship between Em with the Ta concentration. The results revealed the diffusion of mono-vacancy would be promoted in W-Ta alloying system. (C) 2017 Elsevier B.V. All rights reserved.
