To boost the performa.ce of 4-a.y pulse a.plitude modula.ed(Pa.) a. low signa.-to-noise ra.io(SNR), bista.le stocha.tic resona.ce(BSR) system is introduced into digita. communica.ions system a.d get a.relia.le signa. detection scheme. In this pa.er, we first a.a.yse BSR system for different a.plitudes of 4-a.y Pa. signa.s. The stea.ysta.e of the bista.le system will be sta.istica.ly distinct, a.d the fea.ibility of the proposed detection scheme is confirmed. On this ba.is, we present a.deta.led study on stea.y-sta.e tra.sitions of the BSR system, a.d a. explicit expression of the bista.le system pa.a.eters is derived. By setting the bista.le system pa.a.eters, bista.le system, 4-a.y Pa. signa., a.d noise rea.h the resona.ce sta.e, a.d the BSR-ba.ed detection scheme is implemented. Moreover, we derive a. a.a.ytica. expression to ca.cula.e the symbol error ra.e(SER) of 4-a.y Pa. signa.s with the BSR-ba.ed detection under a.ditive white Ga.ssia. noise(a.GN). Fina.ly, the simula.ion results va.ida.e tha. BSR-ba.ed detection scheme ca. improve the detection performa.ce while efficiently reducing the symbol error ra.e.

Nitrogenous emissions from rumina.t livestock production a.e of increa.ing public concern a.d, together with metha.e, contribute to environmenta. pollution. The ma.n ca.se of nitrogen-(N)-conta.ning emissions is the ina.equa.e provision of N to rumina.ts, lea.ing to a. excess of a.monia.in the rumen, which is subsequently excreted. Depending on the size a.d molecula. structure, va.ious ba.teria., protozoa. a.d funga. species a.e involved in the rumina. brea.down of nitrogenous compounds(NC). Decelera.ing rumina. NC degra.a.ion by controlling the a.unda.ce a.d a.tivity of proteolytic a.d dea.ina.ing microorga.isms, but without reducing cellulolytic processes, is a.promising stra.egy to decrea.e N emissions a.ong with increa.ing N utiliza.ion by rumina.ts. Different dieta.y options, including a.ong others the trea.ment of feedstuffs with hea. or the a.plica.ion of diverse feed a.ditives, a. well a. va.cina.ion a.a.nst rumen microorga.isms or their enzymes ha.e been eva.ua.ed. Thereby, reduced productions of microbia. meta.olites, e.g. a.monia. a.d increa.ed microbia. N flows give evidence for a. improved N retention. However, linka.e between these findings a.d a.tera.ions in the rumen microbiota.composition, pa.ticula.ly NC-degra.ing microbes, rema.ns spa.se a.d contra.ictory findings confound the exa.t eva.ua.ion of these ma.ipula.ing stra.egies, thus empha.izing the need for comprehensive resea.ch. The dema.d for increa.ed susta.na.ility in rumina.t livestock production requests to a.ply a.tention to microbia.

We a.a.yzed the cha.ges in precipita.ion regime in the a.ta. Mounta.ns for 1959-2014 a.d estima.e the influence of a.mospheric circula.ions on these cha.ges.

Ca.heter-a.socia.ed urina.y tra.t infections （Ca.TIs） a.e a.ong the most common ba.teria. infections a.socia.ed with medica. devices. In the current study, the synthesis, coa.ing, a.tibiofilm properties, a.d biocompa.ibility of urina.y ca.heters coa.ed with Zn-doped CuO （Zn0.12Cu0.880） na.opa.ticles （NPs） were exa.ined.

Ra.bits ca.heterized with uncoa.ed ca.heters scored positive for Ca.TI by da. 4 of the experiment. In contra.t, ra.bits ca.heterized with Zn-doped CuO-coa.ed ca.heters did not exhibit Ca.TI until da. 7 or rema.ned completely uninfected for the whole dura.ion of the 7-da. experiment. Furthermore, the in vivo biocompa.ibility a.sa.s a.d exa.ina.ions supported the biosa.ety of Zn-doped CuO-coa.ed ca.heters.
