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..

The Standard Model of partic.e physic., whic. c.ntains the field theories for the elec.ro-weak interac.ion (QED) and the strong interac.ion (Qc.), is an extremely suc.essful theory desc.ibing a huge variety of phenomena at the atomic.and subatomic.level with inc.edible ac.urac.. However, the inner workings of the strong interac.ion for systems c.arac.erised by small momentum transfers (of the order ofΛQc.or smaller) are still not fully understood.

Dialec.ic.l Thermodynamic.’Solution to the c.nc.ptual Imbroglio That Is the Reversible Path

引用

Journal of High Energy Physic., Gravitation and c.smology 2024年第2期10卷 775-799页

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.

A Bayesian Mixture Model Approac. to Disparity Testing

引用

Applied Mathematic. 2024年第3期15卷 214-234页

作者： Gary c. Mc.onald Department of Mathematic. and Statistic. Oakland University Rochester USA

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.

Exploring a New Lifetime Distribution for Modelling the Waiting Time of Bank c.stomers

引用

Journal of Applied Mathematic. and Physic. 2024年第1期12卷 194-209页

作者： Simon A. Ogumeyo Jac.b c. Ehiwario Festus c. Opone Department of Mathematic. Delta State University of Science and Technology Ozoro Nigeria Department of Statistic. University of Delta Agbor Nigeria Department of Statistic. Delta State University of Science and Technology Ozoro Nigeria

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.
