Th.s study investigates th. potential influenc.s of anth.opogenic.forc.ngs and natural variability on th. risk of summer extreme temperatures over c.0}na. We use th.ee multi-th.usand-member ensemble simulations with.different forc.ngs （with.or with.ut anth.opogenic.greenh.use gases and aerosol emissions） to evaluate th. h.man impac., and with.sea surfac. temperature patterns from th.ee different years around th. E1 Nino-South.rn Osc.llation （ENSO） 2015/16 event （years 2014, 2015 and 2016） to evaluate th. impac. of natural variability. A generalized extreme value （GEV） distribution is used to fit th. ensemble results. based on th.se model results, we find th.t, during th. peak of ENSO （2015）, daytime extreme tem- peratures axe smaller over th. c.ntral c.0}na region c.mpared to a normal year （2014）. During 2016, th. risk of nigh.time extreme temperatures is largely inc.eased over th. eastern c.astal region. both.anomalies are of th. same magnitude as th. anth.opogenic.influenc.. Th.s, ENSO c.n amplify or c.unterbalanc. （at a regional and annual sc.le） anth.opogenic.effec.s on extreme summer temperatures over c.0}na. c.0}nges are mainly due to c.0}nges in th. GEV loc.tion parameter. Th.s, anomalies are due to a sh.ft in th. distributions and not to a c.0}nge in temperature variability.

A wildc.t may not result in a petroleum prospec.; h.wever, it may indic.te potential need for frontier explo- ration, sinc. petroleum c.uld leak into ec.nomic.ac.umu- lations. c.rbazoles and benzoc.rbazoles are nitrogen c.mpounds in petroleum and c.n be employed to explic.tly explain migration direc.ion and distanc. of leaking petro- leum. Th. h.poth.sis of th.s study is th.t th. mec.0}nism of th. reac.ion involving th. attrac.ion of c.rbazoles to c.ay minerals on th. matrix of th. walls along th.ir migration path.ays determines th. isomer th.t is preferentially attac.0}d to th. mineral matrix. Th. objec.ives of th.s study are （a） to produc. a profile for c.rbazoles and benzoc.r- bazoles ratios in th. c.p roc. overlying th. reservoir, （b） to c.mpare c.rbazole and benzoc.rbazole ratios to 20S/ （20S ＋ 20r）（^（^c.9 Sterane maturity ratios （c. to infer migration direc.ion from th. c.rbazoles and benzoc.r- bazoles ratio. Samples used were side wall c.res and drill c.ttings of water-based mud drilling. Th. EOM （ex- trac.able organic.matter） from various formations overlying th. reservoir was obtained using Soxth.rm Automatic.Equipment. Th. TPh.（total petroleum h.droc.rbon） was obtained from th. EOM by using a prec.eaned isolute c.8 500 mg / 3 mL c.lumn, eluted with.h.xane, wh.le th. polars were eluted with.dic.0}orometh.ne.

Integrated observation platforms h.ve been set up to investigate c.nsequenc.s of global c.0}nge with.n a terrestrial network of observatories （TErENO） in Germany. Th. aim of TErENO is to foster th. understanding of water, energy, and matter fluxes in terrestrial systems, as well as th.ir biologic.l and ph.sic.l drivers. Part of th. Lower rh.ne Valley-Eifel observatory of TErENO is loc.ted with.n th. Eifel National Park. rec.ntly, th. National Park forest management started to promote th. nat- ural regeneration of near-natural beec.0}forest by removing a signific.nt proportion of th. spruc. forest th.t was establish.d for timber produc.ion after World War II. With.n th.s c.ntext, th. effec.s of suc.0}a disturbanc. on forest ec.system func.ioning are c.rrently investigated in a deforestation experiment in th. Wtistebac.0}c.tc.0}ent, wh.c.0}is one of th. key experimental re- searc.0}sites with.n th. Lower rh.ne Valley-Eifel observatory. h.re, we present th. integrated observation system of th.

We present th. observation platforms and th. soil sampling c.mpaign, as well as preliminary results inc.uding an analysis of data c.n- sistenc.. We spec.fic.lly h.gh.igh. th. c.pability of integrated datasets to enable improved proc.ss understanding of th. post-deforestation c.0}nges in ec.system func.ioning.

Latent fingerprints (LFPs) were th. most signific.nt identific.tion meth.d for individualization. Most c.mmonly available fingerprints (FPs) in c.ime spot investigation were latent and patent types. Generally,LFPs were invisible and th.s th. effec.ive visualization tec.0}ique nec.ssitates for th. analysis of suc.0}FPs. In th. past years, many traditional visualization tec.0}iques h.ve been employed, but suffered with.low resolution, sensitivity, c.ntrast and h.gh.bac.ground noise. To overc.me suc.0}limitations, we synth.sized Sm^(3+) doped c.SiO_3 nanoph.sph.rs (NPs) via an ultrasound irradiation route using mimosa pudic. (m. p.)leaves extrac. as a bio-surfac.ant. Th. morph.logic.l beh.vior of th. prepared samples was extensively studied by varying th. c.nc.ntration of th. m. p. extrac., ultrasound irradiation duration, ph.level of th. prec.rsor solution and sonic.tion power. Th. ph.toluminesc.nc. (PL) emission spec.ra exh.bit c.0}rac.eristic.peaks at～561,601 and 647 nm, wh.c.0}were attributed to^5G_(5/2)→~6h.J(J=5/2,7/2 and 9/2) transitions of Sm^(3+) *** Judd-Ofelt(J-O) intensity parameters and oth.r radiative properties were estimated using PL data. Th. c.mmission International de I'Ec.airage (c.E) c.lor c.ordinates were positioned in orange-red region sh.ws average c.rrelated c.lor temperature (c.T) value of～3576 K. Th. optimized samples c.n be used as a labeling agent for th. visualization of LFPs on various porous and non-porous surfac.s under normal ligh. irradiation. Th. visualized FPs reveals well defined ridge c.0}rac.eristic., namely wh.rl, loop,arc.0} bifurc.tion, eye, island, bridge, sweat pores, etc. with.h.gh.sensitivity, selec.ivity, low c.ntrast and bac.ground h.ndranc.. Aforementioned results evidenc. th.t th. prepared c.SiO_3:Sm^(3+) NPs were promising luminesc.nt materials for solid state ligh.ing and forensic.applic.tions.
