PM2.5 is the key reason for frequent occurrence of smog; therefore, identifying its driving factors has far-reaching significance prevention and control air pollution. Based on long-term remote sensing inversion data, 21 in fields nature humanities were selected, random forest model was applied to study influencing concentration Beijing–Tianjin–Hebei urban agglomeration (BTH) from 2000 2016. Th...

We tested the Binding Threshold Hypothesis (BTH) for activation of olfactory receptors (ORs): To activate an OR, the odorant must bind to the OR with binding energy above some threshold value. The olfactory receptor (OR) 912-93 is known experimentally to be activated by ketones in mouse, but is inactive to ketones in human, despite an amino acid sequence identity of approximately 66%. To invest...

We recently found evidence for anatomic and physical linkages between the astroglial Na(+)-dependent glutamate transporters (GLT-1/EAAT2 and GLAST/EAAT1) and mitochondria. In these same studies, we found that the glutamate dehydrogenase (GDH) inhibitor, epigallocatechin-monogallate (EGCG), inhibits both glutamate oxidation and Na(+)-dependent glutamate uptake in astrocytes. In the present study...

Over the past decade, plant heat shock factors (Hsfs) have been associated mainly with responses to abiotic stress (von Koskull-Döring et al., 2007), yet, until this report, they have not been linked to primed defense gene activation or pathogen-induced systemic acquired resistance (SAR). Hsfs are a diverse group of proteins that regulate genes encoding heat shock proteins (von Koskull-Döring e...

Abstract The formation of world-class megalopolises has been a goal urban development agencies around the world owing to their economic advantages. On bids becoming megalopolis, water availability is factor that requires consideration. China set an ambitious developing megalopolis in water-scarce Beijing-Tianjin-Hebei (BTH) region. This study investigates challenge BTH region faces and effects ...

The urbanization process leads to the enhancement of urban heat island (UHI) effect, and high temperature brought by it exacerbates risk exposure seriously endangers human health. Analyzing spatiotemporal characteristics levels is important for formulating prevention control measures. Therefore, this study analyzes based on UHI footprint (FP) explores relationship between factors in Beijing–Tia...

Abstract. An advanced approach of conditional non-linear optimal perturbation (CNOP) was adopted to identify the sensitive area for targeted observations meteorological fields associated with PM2.5 concentration forecasts a heavy haze event that occurred in Beijing–Tianjin–Hebei (BTH) region, China, from 30 November 4 December 2017. The results show few specific regions southern and northwester...

The use of resistance inducers is a novel strategy to elicit defense responses in strawberry fruit to protect against preharvest and postharvest decay. However, the mechanisms behind the specific resistance inducers are not completely understood. Here, global transcriptional changes in strawberry fruit were investigated using RNA-Seq technology. Preharvest, benzothiadiazole (BTH) and chitosan w...

Industrial agglomeration is a highly prominent geographical feature of economic activities, and it an important research topic in geography. However, mechanism-based explanations industrial often differ due to failure distinguish properly between the spatial distribution industries stages agglomeration. Based on micro data from three national censuses, this study uses Duranton-Overman (DO) inde...
