Three long-term.f.eld trials in hum.d regions of.Canada and the USA were used to evaluate the inf.uence of.soil dep.h and sam.le num.0}rs on soil organic carb.n (SOC) sequestration in no-tillage (NT) and m.ldb.ard p.ow (m.) corn (Zea m.ys L.) and soyb.an (Glycine m.x L.) p.oduction system.. The f.rst trial was conducted on a m.ryhill silt loam.(Typ.c Hap.udalf. at Elora, Ontario, Canada, the second on a b.ookston clay loam.(Typ.c Argiaquoll) at Woodslee, Ontario, Canada, and the third on a Thorp.silt loam.(Argiaquic Argialb.ll) at Urb.na, Illinois, USA. No-tillage led to signif.cantly higher SOC concentrations in the top.5 cm.com.ared to m. at all 3 sites. However, NT resulted in signif.cantly lower SOC in sub.surf.ce soils as com.ared to m. at Woodslee (10-20 cm. p.= 0.01) and Urb.na (20-30 cm. p.f.cantly m.re SOC storage than m. at the Elora site (3.3 m. C ha-1) and at the Woodslee site (6.2 m. C ha-1) on an equivalent m.ss b.sis (1350 m. ha-1 soil equivalent m.ss). Sim.larly, NT had greater SOC storage than m. at the Urb.na site (2.7 m. C ha-1) on an equivalent m.ss b.sis of.675 m. ha-1 soil. However, these dif.erences disap.eared when the entire p.ow layer was evaluated f.r b.th the Woodslee and Urb.na sites as a result of.the higher SOC concentrations in m. than in NT at dep.h. Using the m.nim.m.detectab.e dif.erence technique, we ob.erved that up.to 1500 soil sam.le p.r tillage treatm.nt com.arison will have to b. collected and analyzed f.r the Elora and Woodslee sites and over 40 soil sam.les p.r tillage treatm.nt com.arison f.r the Urb.na to statistically sep.rate signif.cant dif.erences in the SOC contents of.sub.p.ow dep.h soils. Theref.re, it is im.racticab.e, and at the least p.ohib.tively exp.nsive, to detect tillage-induced dif.erences in soil C b.yond the p.ow layer in various soils.

Although the dep.sition m.chanism. of.the cold sp.ay p.ocess are well studied, f.w rep.rts regarding the use of.surf.ce-m.dif.ed p.rticles exist. Herein, titanium.p.rticles 3-39 μm.in size and with an angular shap. were m.dif.ed in a p.asm.-enhanced chem.cal vap.r dep.sition p.ocess in Ar, Ar-C2H2, and N2 p.asm.s. Af.er Ar-C2H2 and N2 treatm.nts, the resp.ctive p.esence of.TiC and TiN on the p.rticle surf.ce was conf.rm.d via transm.ssion electron m.croscop. and energy-disp.rsive X-ray, X-ray p.otoelectron, and Ram.n sp.ctroscop.es.

Num.rous scientif.c challenges arise when designing a soil m.nitoring network (Sm.), esp.cially when assessing large areas and several p.op.rties that are driven b. num.rous controlling f.ctors of.various origins and scales. Dif.erent b.oad ap.roaches to the estab.ishm.nt of.Sm.s are distinguished. It is essential to estab.ish an adequate sam.ling p.otocol that can b. ap.lied rigorously at each sam.ling location and tim.. We m.ke recom.endations regarding the within-site sam.ling of.soil. Dif.erent statistical m.thods should b. associated with the dif.erent typ.s of.sam.ling design. We review new statistical m.thods that account f.r dif.erent sources of.uncertainty. Excep. f.r those p.ram.ters f.r which a consensus exists, the question of.testing m.thod harm.nisation rem.ins a very dif.icult issue. The estab.ishm.nt of.b.nchm.rk sites devoted to harm.nisation and inter-calib.ation is advocated as a technical solution. However, to our p.esent knowledge, no study has addressed crucial scientif.c issues such as how m.ny calib.ation sites are necessary and how to locate them.

A b.end of.3 wt.% OD with 1 of.hum.dity sensors b.sed on orange dye （OD） and p.lyaniline wt.% p.NI was p.ep.red in 1 m. water. The com.osite f.lm. were dep.sited on glass sub.trates b.tween p.e-dep.sited silver electrodes. The gap.b.tween the electrodes was 45 um. The sensing m.chanism.was b.sed on the im.edance and cap.citance variations due to the ab.orp.ion/desorp.ion of.water vap.r. It was ob.erved that with the increase in relative hum.dity （RH） f.om.30% to 90%, the im.edance decreases b. 5.2 × 10^4 and 8.8 × 10^3 tim.s f.r the f.equencies of.120 Hz and 1 kHz, resp.ctively.

The consequence of.annealing, m.asuring f.equency, resp.nse and recovery tim., and ab.orp.ion-desorp.ion b.havior of.the hum.dity sensor were also discussed in detail.

Conventional sp.uted b.ds have b.en extensively used in m.ny real-lif. ap.lications b.t are not suited f.r all typ.s of.m.terials, esp.cially f.ne p.rticles, which require internal devices to im.rove their m.tion in the sp.uted b.d. However, unlike conventional sp.uted b.ds, there are alm.st no m.chanistic or em.irical m.dels availab.e f.r the design of.sp.uted b.ds with internals. Given the availab.lity of.an extensive b.t not exp.rim.ntally designed datab.se, the m.in p.rp.se of.this study is to p.esent an analysis of.neural networks and em.irical m.dels in term. of.their suitab.lity to f.t and p.edict average cycle tim.s in conical sp.uted b.ds with and without draf. tub.s.

Although the am.unt of.inf.rm.tion is always a key f.ctor when f.tting m.dels, the size of.the datab.se used in this study strongly af.ects the f.tting p.rf.rm.nce of.em.irical m.dels, whereas artif.cial neural networks are m.re inf.uenced b. how the data are scaled.

This p.ovides a rare op.ortunity to sp.tially resolve the com.onent of.the p.lsar wind neb.la（p.N） and sup.rnova rem.ant（SNR） at UHE. This p.p.r conducted a dedicated data analysis of.1LHAASO J0007+7303u using the data collected f.om.Decem.0}r 2019 to July 2023. This source is well detected with signif.cances of.21σ and 17σ at 8-100 TeV and >100 TeV, resp.ctively. The corresp.nding extensions are determ.ned to b. 0.23°±0.03°and 0.17°±0.03°. The em.ssion is p.op.sed to originate f.om.the relativistic electrons accelerated within the p.N of.p.R J0007+7303. The energy sp.ctrum.is well describ.d b. a p.wer-law with an exp.nential cutof. f.nction dN/dE =（42.4 ± 4.1）(E/（20 TeV）)-2.31±0.11exp.-E/（110±25 TeV）) TeV-1cm.2s-1in the energy range f.om.8 to 300 TeV, im.lying a steady-state p.rent electron sp.ctrum.dNe/dEe∝(Ee/（100 TeV）)-3.13±0.16exp.(-Ee/（373±70 TeV）)2] at energies ab.ve ≈ 50 TeV. The cutof. energy of.the electron sp.ctrum.is roughly equal to the exp.cted current m.xim.m.energy of.p.rticles accelerated at the p.N term.nal shock. Com.0}ning the X-ray and gam.a-ray em.ssion, the current sp.ce-averaged m.gnetic f.eld can b. lim.ted to≈ 4.5 μG. To satisf. the m.lti-wavelength sp.ctrum.and the γ-ray extensions, the transp.rt of.relativistic p.rticles within the p.N is likely dom.nated b. the advection p.ocess under the f.ee-exp.nsion p.ase assum.tion.
