In this pa.er we present a.new optimiza.ion a.gorithm, a.d the proposed a.gorithm opera.es in two pha.es. In the first one, multiobjective version of genetic a.gorithm is used a. sea.ch engine in order to genera.e a.proxima.e true Pa.eto front. This a.gorithm is ba.ed on concept of co-evolution a.d repa.r a.gorithm for ha.dling nonlinea. constra.nts. a.so it ma.nta.ns a.finite-sized a.chive of non-domina.ed solutions which gets itera.ively upda.ed in the presence of new solutions ba.ed on the concept e-domina.ce. Then, in the second sta.e, rough set theory is a.opted a. loca. sea.ch engine in order to improve the sprea. of the solutions found so fa.. The results, provided by the proposed a.gorithm for benchma.k problems, a.e promising when compa.ed with exiting well-known a.gorithms. a.so, our results suggest tha. our a.gorithm is better a.plica.le for solving rea.-world a.plica.ion problems.

Ba.kground: The myometrium a. the loca.ion of the CS (ca.sa.ea. section) sca.s, a.so known a. residua. myometrium thickness (RMT), is la.ger a.ter a.double-la.er uterine closure procedure tha. following a.single-la.er one. It ma. lessen the forma.ion of a.niche tha. is the myometrium’s disruption a. the loca.ion of the sca. of the uterus. Gynecologica. ma.ifesta.ions, obstetric problems in a.future pregna.cy a.d birth, a.d ma.be subfertility a.e linked to thin RMT a.d a.niche. Objective: To a.certa.n if double-la.er unlocked closure of the uterus is better tha. single-la.er one in terms of post-menstrua. spotting a.d niche development following a.first CS. Pa.ients a.d Methods: In this ra.domized clinica. study, 287 pa.ients were eva.ua.ed for qua.ifying. Of a.l eligible individua.s, 57 pa.ients were excluded from the study ba.ed on the inclusion criteria. Results: The va.ia.ion in a.es, gesta.iona. a.e, body ma.s index (BMI), a.d cesa.ea. section indica.ions between the two a.signed groups is sta.istica.ly insignifica.t. However, postmenstrua. spotting wa. sta.istica.ly significa.tly more common in single-la.er group compa.ed to in double-group. The current study revea.ed ultra.ound findings suggestive of niche forma.ion wa. sta.istica.ly significa.tly more common in single-la.er group compa.ed to in double-la.er group. Conclusion: a. evident from the current study, it demonstra.es the a.va.ta.es of double-la.er unlocked closure of the uterus over single-la.er one in terms of post-menstrua. spotting a.d niche development following first-time cs. Thus, we deduced tha. fewer niches a.e formed, a.d fewer menstrua. spotting occurs in the presence of double unlocked la.ers closure. To a.certa.n the impa.t of uterus closure method on post-opera.ive niche development a.d the risk of obstetrics a.d gyna.cologica. problems, further prospective tria.s with extended follow-up periods a.e required.

With a.low resolution 1-bit a.C on its receiver(RX) side, MIMO with 1-bit a.C took a.considera.le step in the fulfillment of the ha.dwa.e complexity constra.ns of the internet of things(IoT) PHY la.er design. However, a.plying 1-bit a.C a. MIMO RX results in severe nonlinea. qua.tiza.ion error. By which, a.most a.l received signa. a.plitude informa.ion is completely distorted. Thus, MIMO cha.nel estima.ion is considered a. a.ma.or ba.rier towa.ds pra.tica. rea.iza.ion of 1-bit a.C MIMO system. In this pa.er, two efficient spa.sity-ba.ed cha.nel estima.ion techniques a.e proposed for 1-bit a.C MIMO systems, na.ely the low complexity spa.sity-ba.ed cha.nel estima.ion(LCSCE), a.d the itera.ive a.a.tive spa.sity cha.nel estima.ion(Ia.CE). In these techniques, the spa.sity of the 1-bit a.C MIMO cha.nel is exploited to propose a.new a.a.tive a.d itera.ive compressive sensing(CS) recovery a.gorithm to ha.dle the 1-bit a.C qua.tiza.ion effect. The proposed a.gorithms a.e tested with the sta.e-of-the-a.t 1-bit a.C MIMO consta.t envelope modula.ion(MIMO-CEM). The 1-bit a.C MIMO-CEM system is chosen a. it fulfills both energy a.d ha.dwa.e complexity constra.nts of the IoT PHY la.er. Simula.ion results revea. the high effectiveness of the proposed a.gorithms in terms of spectra. efficiency(SE) a.d computa.iona. complexity. The proposed LCSCE reduces the computa.iona. complexity of the 1-bit a.C MIMO-CEM cha.nel estima.ion by 86%, while the Ia.CE reduces it by 96% compa.ed to the recent techniques of MIMO-CEM cha.nel estima.ion. Moreover, the proposed LCSCE a.d Ia.CE improve the spectrum efficiency by 76 % a.d 73 %, respectively, compa.ed to the recent techniques.
