Performance of Xpert MTB/RIF Ultra and Xpert MTB/RIF for the Diagnosis of Tuberculosis through Testing of Formalin-fixed Paraffin-embedded Tissues

Tuberculosis (TB) is a significant infectious disease caused by Mycobacterium tuberculosis (MTB). In 2017, 10.0 million new TB cases and 1.3 million deaths were reported globally, according to World Health Organization (WHO). The Mycobacterial culture test is the gold standard for diagnosis but the positive rate is only about 30%, and it is even lower with extrapulmonary tuberculosis. For sputum-negative pulmonary and extrapulmonary TB, pathological examination plays an important role in diagnosis. The detection of MTB in formalin-fixed paraffin-embedded (FFPE) tissues is critical for the definite pathological diagnosis of culture-negative TB. Accurate diagnosis is essential in reducing TB-related morbidity and mortality. Molecular pathological tests detecting MTB DNA have shown advantages in improving diagnostic sensitivity.
ETAS Model Analysis on the Chang Island Earthquake Swarm in Shandong Province,China

Influenced by the layout of seismic network and the location of earthquakes,earthquake catalogs are often incomplete;such incompleteness of earthquake catalogue directly affects the analysis of sequence activity characteristics.In this paper,the GPU-acceleration-based g template matching method is used to scan the continuous waveforms of Chang Island earthquake swarm in Shandong Province from February 9 to August 20,2017.In total,15,286 earthquakes events were detected,which was more than 6 times compared with those in network catalogue and thus reduced the magnitude of completeness from 1.0 to 0.5.Based on the intergrated catalogue of earthquakes,the characteristics of Chang Island earthquake swarm were then analyzed using the Epidemic Type Aftershock Sequences (ETAS) model.The stochastic components in the ETAS model are used as a proxy for possible earthquake triggered by external forces (fluids).The results show that the proportion of earthquakes triggered by external forces of Chang Island swarm increases gradually (from 31.9% to 63.5%) and then decreases.The latter stage of swarm development is mainly affected by the self-excitation of earthquakes,suggesting that the fluids play an important role in the development of the Chang Island swarm.However,the triggering intensity of fluids to microseismicity is divergent in different periods,which may be related to the process of fluid permeation.
Architectural Models and Their Contexts in China's 20~(th)-Century Architectural Heritage: An Overview

The article explores the morphological evolution of China's 20~(th)-century architecture chronologically. Chinese Neoclassicism has played a major role in forming the 20~(th)-century heritage buildings surviving today. The phenomenon of Neoclassicism emerged because of the late arrival of China's modernisation and industrialisation process compared with the West. In turn, in accepting and contesting Western culture, the Chinese elite have consciously relied upon architecture as a vehicle to uphold visible symbols of national Chinese identity and traditional Chinese culture. Meanwhile, in the foreign settlements of the treaty ports such as Shanghai, the Western Neoclassical style, along with other imported construction trends, also forms part of China's 20~(th)-century architectural heritage. Western Neoclassicism's influence on China's new architecture became even more evident in the mid-20~(th)century, with the modern architectural heritage in Tiananmen Square as its exemplar. Nevertheless, the impact of Western modernist architecture on China's architecture was minimal. It was not until the 1980s, as China reopened to the world, that various schools of thought from the post-industrial West flowed into China, which significantly enriched the types and sources of China's 20~(th)-century architectural heritage. Modern Classicism, late Modernism and Postmodernism all found their way into China's contemporary architecture.
Organic salt mediated growth of phase pure and stable all-inorganic CsPbX_3 (X = I, Br)perovskites for efficient photovoltaics

All-inorganic CsPbX_3 (X = I, Br)perovskites without organic component are promising for long-term stability but face main challenges of facile fabrication and phase stability.Here we discover a general organic methylamine acetate salt mediated growth method to deposit high quality phase pure and stable CsPbX_3 (X = I, Br)perovskite films via a novel precursor consisting of stoichiometric cesium acetate (CsAc), methylamine halide (MAX)and lead halide (PbX~2).Interestingly, these organic salts of CsAc and MAX could efficiently promote the crystallization process especially lower the crystallization temperature, but do not introduce the incorporation of organic MA cation into all-inorganic CsPbX_3 perovskites.These phase pure and stable CsPbX_3 perovskites with tunable band gaps can be fabricated into high efficiency photovoltaics.Our organic salt mediated growth of all-inorganic perovskite not only reveals the all-inorganic CsPbX_3 perovskite's unique crystal growth mechanism but also demonstrates their promising application for photovoltaics.
Low-cost and high safe manganese-based aqueous battery for grid energy storage and conversion

As an effective energy storage technology, rechargeable batteries have long been considered as a promising solution for grid integration of intermittent renewables (such as solar and wind energy).However, their wide application is still limited by safety issue and high cost.Herein, a new battery chemistry is proposed to satisfy the requirements of grid energy storage.We report a simple Cu-Mn battery, which is composed of two separated current collectors in an H_2SO_4-CuSO_4-MnSO_4 electrolyte without using any membrane.The Cu-Mn battery shows an energy density of 40.8 Wh L~(-1), a super-long life of 10,000 cycles (without obvious capacity decay)and negligible self-discharge.And the capital cost of US$ 11.9 kWh~(-1) based on electrolyte is lower than any previous batteries.More importantly, the battery can still work smoothly during thermal abuse test and drill-through test, showing high safe nature.Furthermore, a combination system integrating the Cu-Mn battery and hydrogen evolution is also proposed, which is able to avoid the generation of explosive H_2/O_2 mixture, and presents an efficient approach for grid energy storage and conversion.
Recent multiple evidences for high stability of perovskite optoelectronic devices

Organic-inorganic metal halide perovskite materials are earthabundant and combine the advantages of both inorganic and organic materials, such as solution processing, adjustable band gap, high carrier mobility and high extinction coefficient.They are expected to break the technology bottleneck of traditional semiconductor materials and achieve the evolutionary optoelectronic devices with large-area and high efficiency at low cost [1].
The selection of a primary marker for the Anthropocene

Since Homo sapiens appeared, the planet has experienced continuing environmental changes [1,2].In 2000, Crutzen and Stoermer [3] systematically analysed the global changes caused by human activity over the previous 300 years and suggested that the Holocene epoch ended in the 1750s and a new geological age, the Anthropocene, began.Afterwards, the Anthropocene drew a lot of attention from both scientific community and the general public.The recognition and placement of the Anthropocene/Holocene boundary has been a subject of heated debates over the past two decades.At the 35th International Geological Congress (2016;IGC), the Anthropocene Working Group (AWG)recommended the Anthropocene to be formalised with an epoch rank, with the 1950s as its lower boundary [4].Recently, the AWG voted this recommendation and they plan to submit this proposal to the International Commission on Stratigraphy (ICS)by 2021.Although a lot of imprints found in stratigraphic sections support this view, some studies have also suggested the early Holocene, the 16th century, or the late 18th century as the starting date of Anthropocene.
Cobalt atoms dispersed on hierarchical carbon nitride support as the cathode electrocatalyst for high-performance lithium-polysulfide batteries

Lithium-sulfur batteries are promising candidates for next-generation energy storage but are confronted with several challenges.One of the possible solutions is to design proper cathode electrocatalysts to accelerate the redox interconversion of solvated polysulfide intermediates.Herein,we report cobalt atoms dispersed on hierarchical carbon nitride support as an effective cathode electrocatalyst for lithium-polysulfide batteries.The electrocatalyst material is prepared from the simple reaction between melamine and cyanuric acid in the presence of Co~(2+),followed by the Ar annealing.The product has a unique hierarchical structure consisting of many thin and porous C_3N_4 nanosheets finely dispersed with Co atoms.The atomic dispersion of Co species is confirmed by X-ray absorption experiments.Electrochemical measurements reveal that it can promote the interconversion of polysulfides.As a result,batteries using this cathode electrocatalyst achieve large capacity (~1400 mAh/g at 1.6 mA/cm~2),good rate performance (~800 mAh/g at 12.8 mA/cm~2) and impressive cycling stability under different current densities and different sulfur loadings.
Meridional ITCZ shifts modulate tropical/subtropical Asian monsoon rainfall

The temperature gradient between the northern and southern hemispheres and its influence on the global atmospheric circulations are frontier topics in international climate/paleoclimate studies.Over the past approximately two decades, an important hypothesis in the field of global climate change is that the changes of the Atlantic meridional overturning circulation lead to changes in the temperature gradients between the northern and southern hemispheres, which affect the mean zonal locations of the Intertropical Convergence Zone (ITCZ), as well as the subtropical high and the westerly jet stream of the two hemispheres [1-4].Such a north-south movement of the planetary atmospheric circulations leads to a redistribution of water vapor and energy in different regions, resulting in significant temporal and spatial differences in the observed hydroclimate [5,6].In addition, the variation of the interhemispheric temperature contrasts may also lead to southward displacement of the southern hemisphere westerlies [1,7], which might serve as an "on-off" switch for the global glaciation/deglaciation cycles because the southward displacement of the southern hemisphere westerlies may change the upwelling rates in Southern Ocean, resulting in enhanced release of greenhouse gases such as CO_2 from the deep ocean to the atmosphere [8].This interhemispheric temperature gradient forced meridional shifts of the ITCZ and the subtropical high, together with the El Nino-Southern Oscillation (ENSO), are generally thought to be the two fundamental forcings that drive tropical/subtropical hydroclimatic changes.
5H-dithieno[3,2-b:20,30-d]pyran-5-one unit yields efficient wide-bandgap polymer donors

Recently, great progress has been made in organic solar cells due to the emergence of high-performance nonfullerene acceptors [1-6].Over 16% and 17% power conversion efficiencies (PCEs)were achieved for nonfullerene-acceptor-based single-junction and tandem cells, respectively [7,8].Owing to complementary light absorption, wide-bandgap donor-acceptor (D-A)copolymers are ideal electron-donating partners for nonfullerene acceptors.However, efficient D-A copolymer donors are still limited.The reported donors include: copolymers based on carboxylic esterfunctionalized thiophene [9], copolymers based on benzo[1,2-c:4, 5-c0]dithiophene-4,8-dione [10], copolymers based on benzo[d] [1,2,3]triazole [11] and copolymers based on polycyclic aromatic lactam units [12,13].Novel and high-performance D-A copolymer donors are desired.In this context, we propose using fused-ring aromatic lactone (FRAL)as a building block to develop D-A copolymer donors.The strong electron-withdrawing capability of FRAL unit could lower the highest occupied molecular orbital (HOMO)levels, thus enhancing open-circuit voltage (V_(oc))for solar cells.The extended and rigid molecular plane of FRAL could favour p-p stacking, thus improving the hole mobility of the copolymers and enhancing short-circuit current density (J_(sc))and fill factor (FF).FRAL-based D-A copolymer donors have not been reported yet.In this communication, we report two D-A copolymers, L1 and L2, based on 5H-dithieno[3,2-b:20,30-d]pyran-5-one unit (Fig.1a).L1 and L2 present wide bandgaps and deep HOMO levels.Inverted solar cells with them as the donor and Y6 [14] as the acceptor gave decent PCEs up to 14.36%.
Te_(0.045)S_(0.955)PAN composite with high average discharge voltage for Li-S battery

As a sulfur-containing cathode material, sulfide polyacrylonitrile (SPAN) is expected to be used for longlife lithium-sulfur battery because there is no shuttle effect occurred in its charge process. However, its specific capacity and discharge potential need to be further improved to satisfy the urgent demands for high-performance batteries. In this paper, Te_(0.045)S_(0.955)PAN composite was synthesized by co-heating Te_xS_(1-x) and PAN, and the superior electrochemical performance to that of SPAN was obtained because of doping Te with high conductivity. The as-prepared Te_(0.045)S_(0.955)PAN composite possessed the specific capacity of 675 mAh g~(-1) after 100 cycles at the current density of 0.1 A g~(-1) with high capacity retention of 96.6% compared to the second cycle. Especially, during cycling, Te_(0.045)S_(0.955)PAN showed average discharge voltages of 1.88-1.91 V, which were higher than 1.85-1.88 V for SPAN at the same current density. Thus doping Te provides a new strategy for increasing the energy density of SPAN.
Effect of doped Ni-Bi-B alloy on hydrogen generation performance of Al-InCl_3

In this work, Ni-Bi-B alloy has been synthesized via chemical synthesis method. A new kind of Al-InCl_3- (Ni-Bi-B) composite has been prepared by high energy mechanical ball grinding Al powder with additives. Results show that the doped Ni-Bi-B alloy can significantly improve the hydrogen generation performance of Al-InCl_3 and the catalytic activity is enhanced with the increasing content of Bi in Ni-Bi-B alloy. Under optimal conditions, the hydrogen generation yield and conversion yield of Al-InCl_3-(Ni-Bi-B) reached 1196.8mL g~(-1) and 100.0% at room temperature, respectively. Mechanism study shows five kinds of active sites, such as the fresh surface/defect of Al particle, Al-AlCl_3, Al-In, Al-Bi/B and Al-Ni/B produced during the ball milling process. Their synergistic effect enhances the hydrogen generation performance of Al- InCl_3-(Ni-Bi-B) remarkably. In general, the proposed Al-InCl_3-(Ni-Bi-B) composite is possible to serve as hydrogen generation material for fuel cells.

Ultra-flat broadband microwave frequency comb generation based on optical frequency comb with a multiple-quantumwell electro-absorption modulator in critical state

In this paper,we proposed a novel ultra-flat broadband microwave frequency comb (MFC) generation based on optical frequency comb (OFC) with a multiplequantum- well electro-absorption modulator (MQW-EAM) in critical state.The scheme is simple and easy to adjust.The performance of the MFC generation scheme is investigated using software Optisystem.The results show that the comb spacing of MFC can be adjusted from 5 to 20 GHz by changing RF signal’s frequency and the MFC is almost independent on the linewidth of the tunable laser diode.The performance of the MFC can be improved by reasonably increasing the voltage of the RF,the smallsignal gain of the Erbium-doped fiber amplifier (EDFA) and the responsivity of the photodetector.The MFC generated by this scheme has 300 GHz effective bandwidth with 15 comb lines,whose power variation is 0.02 dB,when the components’ parameters in the Optisystem are set as follows:the power of tunable laser diode (TLD) is 0 dBm,the wavelength is 1552.52 nm,and linewidth is 1 MHz;RF signal’s frequency is 20 GHz and the voltage is 10 V;the reverse bias voltage of MQW-EAM is 6.92 V;the small-signal gain of the EDFA is 40 dB;the responsivity of the photodetector (PD) is 1 A/W.
Preparation of dense Ta-LLZO/MgO composite Li-ion solid electrolyte: Sintering, microstructure, performance and the role of MgO

Cubic phase Li7La3Zr2O12 (LLZO), a member of the Li-Garnet family, is a promising solid electrolyte and has been widely studied in recent years. However, LLZO samples prepared via conventional ambient air sintering reported in the published literature often contain large grains with lower than desired (<94%) relative density. In this study, a non-contact method of co-firing with mother powder method is proposed to prepare high-quality Ta-doped LLZO-MgO composite ceramics. By sintering at 1150°C for 5h, the ceramics can reach relative density of 98.2%, conductivity of 5.17×10~(-4) S cm-1 at 25 °C and fracture strength of ~150MPa. The sintered samples have uniform fine-grained microstructure and high critical current densities of 0.75-0.95mA cm~(-2) at room temperature in Li-Li symmetry cell with Au modification. In addition, systematic sintering experiments and characterizations are conducted to explore the function of MgO in inhibiting the Ta-LLZO grain growth and its existing form inside the composite ceramics.
A multi-layered Ti_3C_2/Li_2S composite as cathode material for advanced lithium-sulfur batteries

Lithium-sulfur (Li-S) batteries with lithium sulfide (Li_2S) as cathode have attracted great attention recently, because of high specific capacity (1166mAh g~(-1)) of Li_2S and potential safety of using Li metal-free anode. Li_2S cathode has lower volume expansion and higher thermal stability than the traditional sulfur cathode. However, the problems of “shuttle effect” and poor electrical conductivity of the cathode material still need to be overcome. In this work, multi-layered Ti_3C_2/Li_2S (ML-Ti_3C_2/Li_2S) composite has been prepared and applied as a cathode in advanced Li-S batteries. The unique multi-layer sheet structure of Ti_3C_2 provides space for the storage of Li_2S, and its good conductivity greatly enhances the usage ratio of Li_2S and improves the conductivity of the whole Li_2S cathode. Compared with commonly used graphene, ML-Ti_3C_2 can trap polysulfides effectively by chemical adsorption and also activate the reaction of Li_2S to polysulfides by forming Ti-S bond. As a result, during the cycling of the batteries with ML-Ti_3C_2/Li_2S cathodes, the activation voltage barrier of the first cycle has decreased to 2.8 V, and the “shuttle effect” has been suppressed effectively. The cycling and rate performances of the ML-Ti_3C_2/Li_2S cathodes have been significantly improved compared to that of graphene/Li_2S cathodes. They maintain a capacity of 450mAh g~(-1) at 0.2 C after 100 cycles, and deliver attractive rate performances of 750, 630, 540, 470 and 360mAh g~(-1) at 0.1 C, 0.2 C, 0.5 C, 1 C, and 2 C, respectively.
Theoretical investigation of lithium ions’ nucleation performance on metal-doped Cu surfaces

Lithium metal batteries (LMBs) of an ultrahigh theoretical energy density have attracted lots of attentions for a wide range of practical applications. However, there are still numerous challenges in LMBs system, such as poor cycling performance, complicated interfacial reactions, low Coulombic efficiency, and uncontrollable lithium dendrites. Understanding Li+ ions’ nucleation mechanism is essential to tackle the uncontrolled growth of lithium dendrites. However, the nucleation behavior of Li+ ions is interfered by the structural complexities of existing substrates during the reduplicative plating/stripping process and the rational mechanism of uniform nucleation of Li+ ions has not been clearly understood from the theoretical point of view. In our work, first-principles theoretical calculations are carried out to investigate the Li+ ions nucleation performance on metal-doped Cu surfaces (MDCSs) and the key descriptors that determines the properties of various MDCSs are systematically summarized. It is found that the introduction of heterogeneous doping Ag and Zn atoms will induce a gradient adsorption energy on MDCSs, and such gradient deposition sites can reduce the diffusion barriers and accelerate the diffusion rates of Li+ ions dynamically. By maneuvering the Li+ ions nucleation on MDCSs, a dendrite-free lithium metal anode can be achieved without the use of porous matrixes and complex synthesis process, which can be attributed to suppress the uncontrollable lithium dendrites for realizing the high-efficiency LMBs.
Investigation of wind energy potentials in Brunei Darussalam

Conventional power generation mainly depends on natural gas and diesel oil in Brunei Darussalam. The power utility company is now thinking of power generation using natural wind. In this paper, wind energy, being one of the most readily available renewable energy sources, was studied. The wind characteristic, velocity and directions were studied using Weibull distribution based on the measurement of wind speed at two different locations in Brunei Darussalam. These wind speed distributions were modeled using the Wind Power program. The wind rose graph was obtained for the wind direction to analyze the wind power density onshore and offshore. Based on this analysis, it has been found that the wind speed of 3 to 5 m/s has a probability of occurrence of 40%. Besides, the annual energy production at a wind speed of 5 m/s has been found to be in the range between 1000 and 1500 kWh for both the locations in Brunei Darussalam.
