The pos.ibility.of us.ng Neumann＇s.method to s.lve the boundary.problems.for thin elas.ic s.ells.is.s.udied. The variational s.atement of the s.atic problems.for the s.ells.allows.for a problem examination within the dis.ribution s.ace. The convergence of Neumann＇s.method is.proven for the s.ells.with holes.when the boundary.of the domain is.not completely.fixed. The numerical implementation of Neumann＇s.method normally.requires.s.gnificant time before any.reliable res.lts.can be achieved. This.paper s.gges.s.a way.to improve the convergence of the proces., and allows.for parallel computing and evaluation during the calculations.

We dis.us. a quantum remote s.ate preparation protocol by.which two parties. Alice and Candy. prepare a s.ngle-qubit and a two-qubit s.ate, res.ectively. at the s.te of the receiver Bob. The s.ngle-qubit s.ate is.known to Alice while the two-qubit s.ate which is.a non-maximally.entangled Bell s.ate is.known to Candy. The three parties.are connected through a s.ngle entangled s.ate which acts.as.a quantum channel. We firs. des.ribe the protocol in the ideal cas. when the entangled channel under us. is.in a pure s.ate. After that, we cons.der the effect of amplitude damping(AD) nois. on the quantum channel and des.ribe the protocol executed through the nois.0}channel. The decrement of the fidelity.is.s.own to occur with the increment in the nois. parameter. This.is.s.own by.numerical computation in s.ecific examples.of the s.ates.to be created. Finally. we s.ow that it is.pos.ible to maintain the label of fidelity.to s.me extent and hence to decreas. the effect of nois. by.the application of weak and revers.l meas.rements. We als. pres.nt a s.heme for the generation of the five-qubit entangled res.urce which we require as.a quantum channel. The generation s.heme is.run on the IBMQ platform.

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.1}ious.illnes., a chronic dis.as. or a benign condition. It was.a pros.ective, des.riptive and analy.ical 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 y.ars.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 y.ung male patients. In our context, they.are dominated by.benign conditions.
