Abstract The scattering of light by aerosol particles dictates atmospheric visibility, which is a straightforward indicator air quality. It affected numerous factors, such as particle number size distribution, mass concentration (PM 2.5 ), ambient relative humidity (RH), and chemical composition. latter two factors jointly influence the liquid water content (ALWC). Here, backscattering coeffici...

5-Hydroxytryptamine (5-HT) induces proliferation of cancer cells and vascular cells. In addition to 5-HT production by several cancer cells including gastrointestinal and breast cancer, a significant level of 5-HT is released from activated platelets in the thrombotic environment of tumors, suggesting that inhibition of 5-HT signaling may constitute a new target for antiangiogenic anticancer dr...

We explore charge migration in DNA, advancing two distinct mechanisms of charge separation in a donor (d)-bridge ([Bj])-acceptor (a) system, where [Bj] = B1,B2, . , BN are the N-specific adjacent bases of B-DNA: (i) two-center unistep superexchange induced charge transfer, d*[Bj]a --> d[Bj]a+/-, and (ii) multistep charge transport involves charge injection from d* (or d+) to [Bj], charge hoppin...

Abstract. To investigate the characteristics and changes in sources of carbonaceous aerosols northern Chinese cities after implementation Action Plan for Air Pollution Prevention Control 2013, we collected PM2.5 samples from three representative inland cities, i.e., Beijing (BJ), Xi'an (XA), Linfen (LF), January 2018 to April 2019. Elemental carbon (EC), organic (OC), levoglucosan, stable isoto...

We have carried out an independent quantitative evaluation of the galaxy component of the “COSMOS/UKST Southern Sky Object Catalogue” (SSC) and the “APM/UKST J Catalogue” (APM). Using CCD observations our results corroborate the accuracy of the photometry of both catalogs, which have an overall dispersion of about 0.2 mag in the range 17 ≤ bJ ≤ 21.5. The SSC presents externally calibrated galax...

Note that the pair of Stirling numbers of the first and second kind is a special case of a GSP [g(t) = e>-l,f(t) = 1n(l + t)]. In the present paper, we define an extended generalized Stirling pair, say {B^n^h), B2{n,k)}, which covers in particular the above known results and other interesting pairs of numbers with combinatorial interpretations. Moreover, similar relations to the orthogonality o...

granulocytic ehrlichiosis in Europe: clinical and laboratory findings for four patients from Slovenia. Use of CRH/he Lyme disease mouse model for the recovery of a Spanish isolate of Borrelia garinii from erythema migrans lesions. To the Editor: Five species of tick-associated rickettsiae have been identified in China; of these, three are human pathogens and two are of unknown pathogenicity (1)...
