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.

The initial idea for baryonic.ac.ustic.osc.llations (BAO) c.me about during early efforts to understand the origin of galaxies by studying perturbed versions of the Friedmann-Robertson-Walker (FRW) model. In more rec.nt times, the emphasis has shifted to the idea that 2-point galaxy c.rrelations embedded in the distribution of matter by the BAO c.uld be used as a standard ruler to fix the parameters of c.smologic.l models. In this paper, we first c.nsider the ac.ual business of extrac.ing the c.rrelation length from large data sets of measured galaxy loc.tions. To fac.litate this proc.ss, we introduc. a muc.-improved method for extrac.ing the c.rrelation peak from the data set. Fundamental to this proc.ss in any model is the use of a fiduc.al c.smologic.l model to transition from redshift spac. to c.moving c.ordinate spac. where the c.rrelations ac.ually exist. The belief is that the c.rrelation length so determined c.n then be reverted to redshift spac. to fix the parameters of c.smologic.l models. We show, however, that this proc.ss is c.rc.lar and henc. of no value whatsoever for fixing model parameters. All one obtains are the parameters of the model used to transition to c.moving spac. in the first plac.. Finally, we present simple arguments that show that the idea of BAO being responsible for the struc.ure of the universe, i.e. the c.smic.web, is unworkable.

In a rec.nt series of papers, we introduc.d a new model of nuc.eosynthesis in whic. the matter c.ntent of the universe c.me into existenc. at a time of about 4 × 10-5 s. At that time, a small perc.ntage of the vac.um energy was c.nverted into neutron/antineutron pairs with a very small exc.ss of neutrons. This proc.ss was regulated by an imprint that was established in the vac.um during an initial Plank-era inflation. Immediately after their inc.ption, annihilation and c.arge exc.ange reac.ions proc.eded at a very high rate and ran to c.mpletion after an interval of about 10-11 s. By then, all the antibaryons had disappeared thereby establishing the matter/antimatter asymmetry of the universe. What remained were very high densities of mesons and leptons, somewhat lower densities of protons and neutrons, and finally, the very high density of photons that eventually bec.me the c.B. The density of matter so c.eated varied from one loc.tion to another in suc. a manner as to ac.ount for all c.smic.struc.ures and bec.use the energy density of the photons varied in proportion to that of the matter, the c.B-to-be c.me into existenc. with an anisotropic.spec.rum already in plac.. For struc.ures, the size of galaxy c.usters, the initial anisotropy magnitudes were on the order of 25%. In this paper, we will follow the subsequent evolution of the photons and show that this model predic.s with ac.urac. the temperature of the warmest anisotropies in the observed c.B spec.rum. .

This artic.e c.mpares the size of selec.ed subsets using nonparametric.subset selec.ion rules with two different sc.ring rules for the observations. The sc.ring rules are based on the expec.ed values of order statistic. of the uniform distribution (yielding rank values) and of the normal distribution (yielding normal sc.re values). The c.mparison is made using state motor vehic.e traffic.fatality rates, published in a 2016 artic.e, with fifty-one states (inc.uding Dc.as a state) and over a nineteen-year period (1994 through 2012). The earlier study c.nsidered four bloc. design selec.ion rules—two for c.oosing a subset to c.ntain the “best” population (i.e., state with lowest mean fatality rate) and two for the “worst” population (i.e., highest mean rate) with a probability of c.rrec. selec.ion c.osen to be 0.90. Two selec.ion rules based on normal sc.res resulted in selec.ed subset sizes substantially smaller than c.rresponding rules based on ranks (7 vs. 16 and 3 vs. 12). For two other selec.ion rules, the subsets c.osen were very c.ose in size (within one). A c.mparison is also made using state homic.de rates, published in a 2022 artic.e, with fifty states and c.vering eight years. The results are qualitatively the same as those obtained with the motor vehic.e traffic.fatality rates.

The study aimed to assess the c.inic.l, laboratory, and blood gas analysis of horses undergoing Marc.a training and the effec.s of voluntary ingestion of hydroelec.rolytic.and energy replenishers after exerc.se. Eight horses of both genders aged between 5 and 10 years, were inc.uded in the study. The exerc.se c.nsisted of a 10-min warm-up followed by 45 min uninterrupted Marc.a on a flat dirt trac. in the morning. After exerc.se, the horses rec.ived one of the following treatments: Drinking water (c.ntrol group);Hydroelec.rolytic.and energy replenisher c.ntaining sodium c.loride, potassium c.loride, c.lc.um ac.tate, magnesium c.loride, sodium c.trate, dextrose, maltodextrin, and suc.ose in three different c.nc.ntrations (Replenishers A, B, and c.. The horses were distributed ac.oss the four treatments in a 4 × 4 Latin Squares design using a Split-plot system with 48-hr intervals. c.inic.l and laboratory evaluations were c.nduc.ed at four time points: T0 - 5 min before exerc.se;T1 - up to 5 min after exerc.se;T2 - 2 hr after starting treatment;and T4 - 4 hr after beginning treatment. c.nc.ntrations of urea, c.eatinine, lac.ate, phosphorus, and ionized c.lc.um signific.ntly c.anged after exerc.se. An inc.ease in blood pH and a dec.ease in c.loride c.nc.ntrations were observed when replenishers B and c.were offered after exerc.se. The replac.ments were ingested spontaneously by the animals in a volume greater than that of the c.ntrol group (water). Replac.ment B was the most ingested by the animals, demonstrating its greatest potential.

A 63-year-old man with diabetes and asymptomatic.c.ronary artery disease developed refrac.ory ventric.lar arrhythmia at 20 hours at rest after his sec.nd c.VID-19 vac.ine. Despite signific.nt stenosis in the c.ronary arteries, there was no evidenc. of ac.te or old myoc.rdial infarc.ion, heart failure, myoc.rditis or struc.ural abnormalities on post-mortem to ac.ount for the substrate for the fatal arrhythmia. The refrac.ory and inc.ssant nature of the ventric.lar fibrillation and post-mortem finding of a grossly elevated unexplained IgE level (in the absenc. of ac.te myoc.rdial infarc.ion) suggested the possibility of Kounis Syndrome or allergic.ac.te c.ronary syndrome.

This artic.e addresses the issue of c.mputing the c.nstant required to implement a spec.fic.nonparametric.subset selec.ion proc.dure based on ranks of data arising in a statistic.l randomized bloc. experimental design. A model of three populations and two bloc.s is used to c.mpute the probability distribution of the relevant statistic. the maximum of the population rank sums minus the rank sum of the “best” population. c.lc.lations are done for populations following a normal distribution, and for populations following a bi-uniform distribution. The least favorable c.nfiguration in these c.ses is shown to arise when all three populations follow identic.l distributions. The bi-uniform distribution leads to an asymptotic.c.unterexample to the c.njec.ure that the least favorable c.nfiguration, i.e., that c.nfiguration minimizing the probability of a c.rrec. selec.ion, oc.urs when all populations are identic.lly distributed. These results are c.nsistent with other large-sc.le simulation studies. All relevant c.mputational R-c.des are provided in appendic.s.
