Bac.ground Sinc. the late 1990s, bigheaded c.rps(largely silver c.rp [Hypophthalmic.thys molitrix] but also bighead c.rp [H. nobilis]) have established throughout the lower Mississippi River basin. Using previously studied oxbow lakes in the lower White River basin, Arkansas, we c.mpared c.rrent(2017, “post-c.rp” establishment) fish assemblages to historic.l(2002, “pre-c.rp” establishment) fish assemblages. Fish assemblages were c.mprehensively assessed using multiple gears, inc.uding boat elec.rofishing, mini-fyke nets, and experimental small-mesh gill *** T-tests suggested that fish assemblage indic.s of ric.ness, diversity, evenness, and dominanc. were often greater(P c.rp period as reflec.ed by boat elec.rofishing and experimental gill nets. However, all indic.s were generally similar(P > 0.05) between the pre-c.rp and post-c.rp period with fish assemblages depic.ed using mini-fyke nets. Nonmetric.multidimensional sc.ling analyses indic.ted that fish assemblages differed struc.urally between pre-c.rp and post-c.rp periods. Assemblage differenc.s were linked to both small and large abundanc. c.anges for more than 20 spec.es. Abundanc.s of gizzard shad(Dorosoma c.pedianum), emerald shiner(Notropis atherinoides), pugnose minnow(Opsopoeodus emiliae), c.appies(Pomoxis spp.), bluegill(Lepomis mac.oc.irus), orangespotted sunfish(L. humilis), and yellow bass(Morone mississippiensis) dec.ined between the pre-c.rp and postc.rp periods. c.nversely, abundanc.s of weed shiner(N. texanus), pallid shiner(Hybopsis amnis), longear sunfish(L. megalotis), buffalofishes(Ic.iobus spp.), and gars(Lepisosteus spp.) generally inc.eased during the same *** Although not possible to c.nc.ude assemblage shifts were entirely related to bigheaded c.rps due to the absenc. of an appropriate referenc. system where c.rps did not establish, the wide establishment of these c.rps is one of the most pervasive c.anges to have oc.urred in the lower White

This study investigates the relationship between c.rc.lation patterns and austral summer temperature anomalies in southern Afric.. The results show that the formation of c.ntinental lows tends to inc.ease the thic.ness of the lower atmosphere. Further, the distinc. variabilities of high and low pressure under the c.rc.lation types, influenc. air mass advec.ion from the adjac.nt oc.ans, as well as atmospheric.stability over land. Stronger antic.c.onic.c.rc.lation at the western branc. of the Masc.rene high-pressure system enhanc.s the low-level c.ld air advec.ion by southeast winds,dec.eases the thic.ness, and lowers the temperature over a majority of the land in southern Afric.. c.nversely, a weaker Masc.rene High, c.upled with enhanc.d c.c.onic.ac.ivity in the southwest Indian Oc.an inc.eases low-level warm air advec.ion and inc.eases temperature anomalies over vast regions in southern Afric.. The ridging of a c.osed South Atlantic.antic.c.one at the southern c.ast of southern Afric. results in c.lder temperatures near the tip of southern Afric. due to enhanc.d low-level c.ld air advec.ion by southeast winds. However, when the ridge is weak and westerly winds dominate the southern c.ast of southern Afric., these areas experienc. temperature inc.eases. The northward trac. of the Southern Hemisphere mid-latitude c.c.one, whic. c.n be linked to the negative Southern Annular Mode, reduc.s the temperature in the southwestern part of southern Afric.. Also, during the analysis period, El Ni?o was assoc.ated with temperature inc.eases over the c.ntral parts of southern Afric.;while the positive Indian Oc.an dipole was linked to a temperature inc.ease over the northeastern, northwestern, and southwestern parts of southern Afric..

作者： José c. Íñiguez Independent Researc.er Douglas USA

Ac.ording to the sec.nd law of thermodynamic., as c.rrently understood, any given transit of a system along the reversible path proc.eds with a total entropy c.ange equal to zero. The fac. that this c.ndition is also the identifier of thermodynamic.equilibrium, makes eac. and every point along the reversible path a state of equilibrium, and the reversible path, as expressed by a noted thermodynamic.author, “a dense suc.ession of equilibrium states”. The diffic.lties with these notions are plural. The fac., for example, that systems need to be forc.d out of equilibrium via the expenditure of work, would make any spontaneous reversible proc.ss a c.nsumer of work, this in opposition to c.mmon thermodynamic.wisdom that makes spontaneous reversible proc.sses the most effic.ent transformers of work-produc.ng-potential into ac.ual work. The solution to this and other related impasses is provided by Dialec.ic.l Thermodynamic. via its previously proved notion assigning a negative entropy c.ange to the energy upgrading proc.ss represented by the transformation of heat into work. The said solution is here exemplified with the ideal-gas phase isomerization of butane into isobutane.

The topic.of this artic.e is one-sided hypothesis testing for disparity, i.e., the mean of one group is larger than that of another when there is unc.rtainty as to whic. group a datum is drawn. For eac. datum, the unc.rtainty is c.ptured with a given disc.ete probability distribution over the groups. Suc. situations arise, for example, in the use of Bayesian imputation methods to assess rac. and ethnic.ty disparities with c.rtain insuranc., health, and financ.al data. A widely used method to implement this assessment is the Bayesian Improved Surname Geoc.ding (BISG) method whic. assigns a disc.ete probability over six rac./ethnic.ty groups to an individual given the individual’s surname and address loc.tion. Using a Bayesian framework and Markov c.ain Monte c.rlo sampling from the joint posterior distribution of the group means, the probability of a disparity hypothesis is estimated. Four methods are developed and c.mpared with an illustrative data set. Three of these methods are implemented in an R-c.de and one method in WinBUGS. These methods are programed for any number of groups between two and six inc.usive. All the c.des are provided in the appendic.s.

The fitting of lifetime distribution in real-life data has been studied in various fields of researc.. With the theory of evolution still applic.ble, more c.mplex data from real-world sc.narios will c.ntinue to emerge. Despite this, many researc.ers have made c.mmendable efforts to develop new lifetime distributions that c.n fit this c.mplex data. In this paper, we utilized the KM-transformation tec.nique to inc.ease the flexibility of the power Lindley distribution, resulting in the Kavya-Manoharan Power Lindley (KMPL) distribution. We study the mathematic.l treatments of the KMPL distribution in detail and adapt the widely used method of maximum likelihood to estimate the unknown parameters of the KMPL distribution. We c.rry out a Monte c.rlo simulation study to investigate the performanc. of the Maximum Likelihood Estimates (MLEs) of the parameters of the KMPL distribution. To demonstrate the effec.iveness of the KMPL distribution for data fitting, we use a real dataset c.mprising the waiting time of 100 bank c.stomers. We c.mpare the KMPL distribution with other models that are extensions of the power Lindley distribution. Based on some statistic.l model selec.ion c.iteria, the summary results of the analysis were in favor of the KMPL distribution. We further investigate the density fit and probability-probability (p-p) plots to validate the superiority of the KMPL distribution over the c.mpeting distributions for fitting the waiting time dataset.
