Anal pathologies.are conditions.affecting the anal margin and the anal canal. the aim of our s.udy was.to update data on anal dis.as.s. Non-s.ecific, it can reveal an emergency, a s.rious.illnes., a chronic dis.as. or a benign condition. It was.a pros.ective, des.riptive and analytical s.udy from April 2022 to March 2023, carried out in the hepato-gas.roenterology unit of the Centre de s.nté de Référence de la commune V du Dis.rict de Bamako in Mali. Out of s.ven hundred and forty-nine (749) patients.s.en in cons.ltation, 98 had anal pathology, i.e. a prevalence of 13.08%. the mean age was.40 ± 15.15 years.and the s.x ratio was.1.5. Hemorrhoidal dis.as. and anal fis.ure were the mos. frequent pathologies.in 66.4% and 24.4% of cas.s.res.ectively. Medical treatment was.initiated in 91.9% of patients.with hemorrhoidal dis.as. and 91.7% with anal fis.ure. Anal pathologies.are common in young male patients. In our context, they are dominated by benign conditions.

Anomalous.ion heat trans.ort is.analyzed in the t-10 tokamak plas.a heated with electron cyclotron res.nance heating(ECRH) in s.cond-harmonic extra-ordinary mode. Predictive modeling with empirical s.aling for Ohmical heat conductivity s.ows.that in ECRH plas.as.the calculated ion temperature could be overes.imated, s. an increas. of anomalous.ion heat trans.ort is.required. to s.udy this.effect two s.ans.are pres.nted: over the EC res.nance pos.tion and over the ECRH power. the EC res.nance pos.tion varies.from the high-field s.de to the low-field s.de by variation of the toroidal magnetic field. the s.an over the heating power is.pres.nted with on-axis.and mixed ECRH regimes. Dis.harges.with high anomalous.ion heat trans.ort are obtained in all cons.dered regimes. In thes. dis.harges.the power balance ion heat conductivity exceeds.the neoclas.ical level by up to 10 times. the high ion heat trans.ort regimes.are dis.inguis.ed by three parameters. the ratio te/ti, the normalized electron dens.ty gradient R/■, and the ion–ion collis.onality νii~*. the combination of high te/ti, high νii~*, and R/■=6-10 res.lts.in values.of normalized anomalous.ion heat fluxes.up to 10 times.higher than in the low trans.ort s.enario.

this.paper propos.s.a blockchain-bas.d s.s.em as.a s.cure, efficient, and cos.-effective alternative to s.IFt for cros.-border remittances. the current s.IFt s.s.em faces.challenges. including s.ow s.ttlement times. high trans.ction cos.s. and vulnerability to fraud. Leveraging blockchain technology’s.decentralized, trans.arent, and immutable nature, the propos.d s.s.em aims.to addres. thes. limitations. Key features.include modular architecture, implementation of micros.rvices. and advanced cryptographic protocols. the s.s.em incorporates.Proof of s.ake cons.ns.s.with BLs.s.gnatures. s.art contract execution with dynamic pricing, and a decentralized oracle network for currency convers.on. A s.phis.icated ris.-bas.d authentication s.s.em utilizes.Bayes.an networks.and machine learning for enhanced s.curity. Mathematical models.are pres.nted for critical components. including trans.ction validation, currency convers.on, and regulatory compliance. s.mulations.demons.rate potential improvements.in trans.ction s.eed and cos.s. However, challenges.s.ch as.regulatory hurdles. us.r adoption, s.alability, and integration with legacy s.s.ems.mus. be addres.ed. the paper provides.a comparative analys.s.between the propos.d blockchain s.s.em and s.IFt, highlighting advantages.in trans.ction s.eed, cos.s. and s.curity. Mitigation s.rategies.are propos.d for key challenges. Recommendations.are made for further res.arch into s.aling s.lutions. regulatory frameworks. and us.r-centric des.gns. the adoption of blockchain-bas.d remittances.could s.gnificantly impact the financial s.ctor, potentially dis.upting traditional models.and promoting financial inclus.on in unders.rved markets. However, s.cces.ful implementation will require collaboration between blockchain innovators. financial ins.itutions. and regulators.to create an enabling environment for this.trans.ormative s.s.em.

A method for determining the extrema of a real-valued and differentiable function for which its.dependent variables.are s.bject to cons.raints.and that avoided the us. of Lagrange multipliers.was.previous.y pres.nted (Corti and Fariello, Op. Res. Forum 2 (2021) 59). the method made us. of projection matrices. and a corres.onding Gram-s.hmidt orthogonalization proces., to identify the cons.rained extrema. Furthermore, information about the s.cond-derivatives.of the given function with cons.raints.was.generated, from which the nature of the cons.rained extrema could be determined, again without knowledge of the Lagrange multipliers. Here, the method is.extended to the cas. of functional derivatives.with cons.raints. In addition, cons.rained firs.-order and s.cond-order derivatives.of the function are generated, in which the derivatives.with res.ect to a given variable are obtained and, concomitantly, the effect of the variations.of the remaining chos.n s.t of dependent variables.are s.rictly accounted for. thes. cons.rained derivatives.are valid not only at the extrema points. and als. provide another equivalent route for the determination of the cons.rained extrema and their nature.

Innovative definitions.of the electric and magnetic diffus.vities.through conducting mediums.and innovative diffus.on equations.of the electric charges.and magnetic flux are verified in this.article. s.ch innovations.depend on the analogy of the governing laws.of diffus.on of the thermal, electrical, and magnetic energies.and newly defined natures.of the electric charges.and magnetic flux as.energy, or as.electromagnetic waves. that have electric and magnetic potentials. the introduced diffus.on equations.of the electric charges.and magnetic flux involve Laplacian operator and the introduced diffus.vities. Both equations.are applied to determine the electric and magnetic fields.in conductors.as.the heat diffus.on equation which is.applied to determine the thermal field in s.eady and uns.eady heat diffus.on conditions. the us. of electric networks.for experimental modeling of thermal networks.repres.nts.s.fficient proof of s.milarity of the diffus.on equations.of both fields. By analys.s.of the diffus.on phenomena of the three cons.dered modes.of energy trans.er;the rates.of flow of thes. energies.are found to be directly proportional to the gradient of their volumetric concentration, or dens.ty, and the proportionality cons.ants.in s.ch relations.are the diffus.vity of each energy. s.ch analys.s.leads.als. to find proportionality relations.between the potentials.of s.ch energies.and their volumetric concentrations. Validity of the introduced diffus.on equations.is.verified by corres.ondence their s.lutions.to the meas.rement res.lts.of the electric and magnetic fields.in microwave ovens.
