In this paper, we examine an emerging variation of the c.assific.tion problem, whic. is known as the inverse c.assific.tion problem. In this problem, we determine the features to be used to c.eate a rec.rd whic. will result in a desired c.ass label. Suc. an approac. is useful in applic.tions in whic. it is an objec.ive to determine a set of ac.ions to be taken in order to guide the data mining applic.tion towards a desired solution. This system c.n be used for a variety of dec.sion support applic.tions whic. have pre-determined task c.iteria. We will show that the inverse c.assific.tion problem is a powerful and general model whic. enc.mpasses a number of different c.iteria. We propose a number of algorithms for the inverse c.assific.tion problem, whic. use an inverted list representation for intermediate data struc.ure representation and c.assific.tion. We validate our approac. over a number of real datasets.

Effec.s a synthetic.Aluminium-Magnesium Silic.te [AMS] has on Avian Influenza Virus (AIV) were tested. Equal amounts of AIV samples and of the AMS were mixed, kept one hour at room temperature before c.ntrifuging. The supernatants were remeasured and tested for, viral titre, Mean Death Time (MDT) and Mortality Rate of c.ic.en Embryos (EMR). Volumes of the viral samples reduc.d at rate of 23.4% ± 5.48%. Viral titres reduc.d signific.ntly (P c.ed c.ic.en embryos reduc.d from 100% to 65%, while MDT of those that died,inc.eased signific.ntly (P c.bation with AMS was repeated on portions of an AIV sample, MDT inc.eased from 64 to 104 hours with the portion inc.bated onc..

The propagation c.arac.eristic. of nonlinear ion–ac.ustic.IA） solitary waves（SWs） are studied in thermal elec.ron–positron–ion plasma c.nsidering the effec. of relativistic.positron beam. Starting from a set of fluid equations and using the reduc.ive perturbation tec.nique, we derive a Korteweg–de Vries（KdV） equation whic. governs the evolution of weakly nonlinear IA SWs in relativistic.beam driven plasmas. The properties of the IA soliton are studied, and it is shown that the presenc. of relativistic.positron beam signific.ntly modifies the c.arac.eristic. of IA solitons.

Biliary c.mplic.tions are signifi c.nt c.uses of morbidity and mortality after orthotopic.liver transplantation (OLT). The estimated inc.denc. of biliary c.mplic.tions after OLT ranges between 10%-25%,however,these numbers c.ntinue to dec.ine due to improvement in surgic.l tec.niques. The most c.mmon biliary c.mplic.tions are stric.ures (both anastomotic.and non-anastomotic. and bile leaks. Most of these problems c.n be appropriately managed with endosc.pic.retrograde c.langiography (ERc.. Other c.mplic.tions suc. as bile duc. stones,bile c.sts,sphinc.er of Oddi dysfunc.ion,and hemobilia,are less frequent and also c.n be managed with ERc. This artic.e will review the risk fac.ors,diagnosis,and endosc.pic.management of the most c.mmon biliary c.mplic.tions after OLT.

Bac.ground: Pain is a major problem for patients suffering from c.ronic.panc.eatitis. Unfortunately, medic.l therapy often fails to adequately c.ntrol pain. c.eliac.plexus bloc. (c.B) is sometimes performed to treat intrac.able pain in patients with c.ronic.panc.eatitis. Aims: Our primary objec.ive was to determine the effec. of c.B for pain management in a c.hort of patients with c.ronic.panc.eatitis. We also sought to quantify opioid use in patients with c.ronic.panc.eatitis. Methods: We reviewed the database of pain referrals for c.ronic.panc.eatitis and rec.rded opioid use for eac. patient. We interviewed all patients who underwent c.B for c.ronic.panc.eatitis at TUH from January 2018-Dec.mber 2020. Effec. of the bloc., duration of pain relief, analgesia requirements, c.mplic.tions and patient satisfac.ion were rec.rded. Results: 62 inpatient referrals were made to the pain servic. over a 3-year period regarding pain management in c.ronic.panc.eatitis. 76% of patients referred for c.ronic.panc.eatitis pain management require regular long-term opioids. Mean daily oxyc.done requirement in this group was 52 mg. 11 of these patients underwent c.B over a 3-year period. Mean age of patients who underwent c.B was 44 years. Effec.ive reduc.ion in pain sc.res (>50% improvement) was ac.ieved in 7 of 11 patients. The mean NRS pain sc.re dec.eased from 9.2 (±0.9) to 4.4 (±3.1). Mean duration of pain relief experienc.d was 69 days. Transient diarrhoea was reported by 1 patient. 4 patients reported a temporary dec.ease in oral analgesia requirement, while 3 patients reported a sustained dec.ease in analgesia requirement post c.B. For those who had further c.Bs, the effec. of repeated interventions was c.mparable to the initial proc.dure. c.nc.usion: High regular opioid c.nsumption is c.mmon in patients with c.ronic.panc.eatitis. c.B c.n provide signific.nt improvement in pain c.ntrol and quality of life in appropriately selec.ed patients. c.B c.n assist with opioid reduc.ion

From the Siwalik Group of Haryana and Himac.al Pradesh, new fossil reptile rec.rds are desc.ibed. The Siwalik fauna from Haryana and Himac.al is rec.rded from the pre-Pinjor and Pinjor beds (Upper Siwalik Subgroup: Plioc.ne—Lower Pleistoc.ne). The reptile fauna inc.udes c.oc.dylus aff. palustris, Gavialis c.. gangetic.s, Rhamphosuc.us c.assidens, Batagur sp., Geoc.emys hamiltoni and Hardella thurjii. The findings are signific.nt as fossil reptiles from the Siwalik Group are sc.nty as c.mpared to the ric.er mammalian fauna.

Rail systems are gradually bec.ming the most desirable form of transit infrastruc.ure around the world, partly bec.use they are bec.ming more environmentally friendly c.mpared with airplanes and automobiles. This paper examines the plac. of emerging c.untries in this move of implementing modern rail system that will eventually enhanc. the realization of a low-c.rbon soc.ety. Network model, transportation model and linear programming algorithms are used to model the present urban rail transport system in Nigeria, as an emerging c.untry, in order to optimize it. Operational researc. methods, inc.uding simplex method and MODI, with the aids of c.mputer software (exc.l solver and LIP solver) were adopted to solve the resulting models. The results showed that optimization of rail transport system will not only reduc. c.rbon emission but also bring about ec.nomic.development whic. is required for the eradic.tion of prevalent poverty in these emerging c.untries.

Simulation c.de for a model of the adaptive immune response seen in flavivirus infec.ions is used to explain the immunopathologic.l c.nsequenc.s seen in West Nile Virus virus (WNV) infec.ions. We use a model that spec.fic.lly handles the differenc.s in how the virus infec.s resting c.lls, the G0 state, versus dividing c.lls, the G1 state, whic. inc.udes vastly inc.eased MHc.I upregulation for resting c.lls over dividing c.lls. The simulation suggests how the infec.ion progresses in a one host model and the results shed insight into the unusual survival c.rve data obtained for this infec.ion: there is an inc.ease in health even though viral load has inc.eased.
