The SkyMapper Southern Sky Survey is carrying out a search for the most metal-poor stars in Galaxy. It identifies candidates by way of its unique filter set which allows estimation stellar atmospheric parameters. includes narrow centered on Ca ii K 3933 Å line, enabling robust estimate metallicity. Promising are then confirmed with spectroscopy. We present analysis Magellan Inamori Kyocera Echelle high-resolution spectroscopy 122 found first two years commissioning observations. Forty-one...
It is well established that stellar effective temperatures determined from photometry and spectroscopy yield systematically different results. We describe a new, simple method to correct spectroscopically derived ("excitation temperatures") of metal-poor stars based on literature sample with -3.3<[Fe/H]<-2.5. Excitation were FeI line abundances in high-resolution optical spectra the wavelength range ~3700 ~7000A, although shorter ranges, up 4750 6800A, can also be employed, compared...
Renal cell carcinoma (RCC) is known for its multidrug resistance. Using data obtained from the cancer transcriptome database Oncomine and proteome The Human Protein Atlas, we identified repression of organic cation transporter OCT2 as a potential factor contributing to oxaliplatin resistance in RCC. By analyzing expression collected patient tissues commercial tissue microarray specimens, demonstrated RCC at both transcription protein levels. Epigenetic analysis revealed that repressed...
A combined adsorption-discharge plasma catalytic process was used for the removal of NOx using zeolites as catalysts without external heating. It found that types carrier gases exert great effect on conversion adsorbed NOx. The is much lower in N2 than Ar plasma, which attributed to reverse reaction, formation reaction. momentary increase oxygen species derived from decomposition considered be main cause their collisions with nitrogen can generate again. Thus, solid carbon added catalyst act...
The SMILE ground segment comprises the Chinese Academy of Sciences (CAS) and European Space Agency (ESA) segment, which collaborate closely on this mission. Ground Support System (GSS) Science Application (SAS) are two important components CAS segment. Development these systems began in 2016, focusing requirements for addressing significant challenges associated with GSS is primarily responsible data reception, mission operations, processing, management, services. It has established an...
We report Pd-catalyzed ortho-C–H methoxylation and chlorination of benzaldehydes by employing monodentate transient directing groups (TDGs) as an alternative strategy to bidentate TDGs. More importantly, a single crystal benzaldehyde imine ortho-cyclopalladium intermediate was successfully obtained, its structure unambiguously determined X-ray diffraction, which clearly showed that it binuclear palladium species bridged pyridone ligand. The utility this approach further demonstrated through...
Benzidine was found to be a novel transient directing group enable Pd-catalyzed direct selenylation of inert C(sp2)–H bonds benzaldehydes. Diverse diarylselenides were readily constructed in high efficiency and satisfactory yields with good functional tolerance. The practical usage the method further demonstrated by enlarged reaction gram scale application facile access two selenoxanthenes one fluorescent probe.
Wastewater-based epidemiology is a promising public health tool that can yield more representative view of the population than case reporting. However, only about 80% U.S. connected to sewers, and characteristics populations missed by wastewater-based are unclear. To address this gap, we used publicly available datasets assess sewer connectivity in location, demographic groups, economic groups. Data from Census’ American Housing Survey revealed was lower average when head household Indian...
In this work, an efficient synthetic route was developed to construct PAHs with diverse shape, width, and edge topology. The precursors of were obtained by using a direct arylation arenes via transient ligand-directed C-H functionalization strategy the cycloaromatization readily achieved Brønsted acid catalyst. This novel provides opportunity build up in highly manner.
Demographic noise, the change in composition of a population due to random birth and death events, is an important driving force evolution because it reduces efficacy natural selection. noise typically thought be set by size environment, but recent experiments with microbial range expansions have revealed substantial strain-level differences demographic under same growth conditions. Many genetic phenotypic exist between strains; what extent do single mutations strength noise? To investigate...
The massive agricultural sector in Northeast China results a huge amount of crop residues, which have long been disposed mainly through "illegal" open burning. A transition local policy occurred 2018, with window approximately 3 months issued for fires. Here, we investigated the responses brown carbon (BrC) to new policy. Persistently high levels BrC mass (estimated as methanol-soluble organic carbon) and absorption coefficient were observed during "legitimate burning" period. Agricultural...
Commercially available 3,5-bis(trifluoromethyl)aniline was found to be a highly efficient monodentate transient directing group (MonoTDG) for the palladium-catalyzed direct dehydrogenative cross-coupling of benzaldehydes with arenes. A diverse set symmetrical and unsymmetrical 9-fluorenones readily obtained in yields 32-72% along excellent regioselectivities broad functional compatibility as well high atom economy under mild conditions via dual carbon-hydrogen (C-H) bond activation sequence.
Genetic drift in infectious disease transmission results from randomness of and host recovery or death. The strength genetic for SARS-CoV-2 is expected to be high due levels superspreading, this substantially impact epidemiology evolution. However, we don’t yet have an understanding how changes over time across locations. Furthermore, noise that data collection can potentially confound estimates drift. To address challenge, develop validate a method jointly infer measurement time-series...
