The conditiona. version of sa.dwiched Tsa.lis rela.ive entropy (CSTRE) is employed to study the bipa.tite sepa.a.ility of one pa.a.eter fa.ily of N-qudit Werner-Popescu sta.es in their 1:N-1 pa.tition. For a.l N, the strongest limita.ion on bipa.tite sepa.a.ility is rea.ized in the limit a.d is found to ma.ch exa.tly with the sepa.a.ility ra.ge obta.ned using a. a.gebra.c method which is both necessa.y a.d sufficient. The theoretica. superiority of using CSTRE criterion to find the bipa.tite sepa.a.ility ra.ge over the one using a.e-rajagopal (a.) q-conditiona. entropy is illustra.ed by compa.ing the convergence of the pa.a.eter x with respect to q, in the implicit plots of a. q-conditiona. entropy a.d CSTRE.

It is k.own tha. the dyna.ica. evolution of a.system, from a. initia. tensor product sta.e of system a.d environment, to a.y two la.er times, t1, t2 (t2 > t1), a.e both completely positive (CP) but in the intermedia.e times between t1 a.d t2 it need not be CP. This revea.s the k.y to the Ma.k.v (if CP) a.d non Ma.k.v (if it is not CP) a.a.a.a. of the intermedia.e dyna.ics. This is brought out here in terms of the qua.tum stocha.tic ma. a.a.d the a.socia.ed dyna.ica. ma. B—without resorting to ma.ter equa.ion a.proa.hes. We investiga.e these fea.ures with four exa.ples which ha.e entirely different physica. origins: 1) a.two qubit Werner sta.e ma. with time dependent noise pa.a.eter;2) Phenomenologica. model of a.recent optica. experiment (Na.ure Physics, 7, 931 (2011)) on the open system evolution of photon pola.iza.ion;3) Ha.iltonia. dyna.ics of a.qubit coupled to a.ba.h of N qubits;4) Two qubit unita.y dyna.ics of Jorda. et a.. (Phys. Rev. a.70, 052110 (2004) with initia. product sta.es of qubits. In a.l these models, it is shown tha. the positivity/nega.ivity of the eigenva.ues of intermedia.e time dyna.ica. B ma. determines the Ma.k.v/non-Ma.k.v na.ure of the dyna.ics.

This study compa.es postopera.ive complica.ion profiles between Wise-pa.tern a.d nipple-spa.ing ma.tectomies in the obese popula.ion. Methods: a.retrospective cha.t review of obese pa.ients (BMI ≥ 30) who underwent sta.ed brea.t reconstruction following Wise-pa.tern a.d nipple-spa.ing ma.tectomies a. our institution between Februa.y 2016 a.d Ja.ua.y 2020 wa. conducted. Complica.ions between cohorts were a.a.yzed using the independent sa.ples t-test (2-sided) a.d the χ2 test. Results: a.tota. of 232 brea.ts (163 Wise-pa.tern, 69 NSM) were re-constructed in 123 obese fema.e pa.ients (85 Wise-pa.tern, 38 NSM). Complica.ion ra.es in both the Wise-pa.tern a.d NSM pa.ient cohorts were simila. following sta.e 1 (Wise-pa.tern: 30.7%, NSM: 39.1%, p = 0.212) a.d sta.e 2 (Wise-pa.tern: 16.6%, NSM: 15.9%, p = 0.907) of reconstruction. No sta.istica.ly significa.t differences in ra.es of infection, dehiscence, seroma. hema.oma.or ma.position of tissue expa.der (TE)/impla.t following sta.e 1 or sta.e 2 were found between cohorts. Conclusions: There were no significa.t differences in postopera.ive complica.ion ra.es between the Wise-pa.tern a.d NSM cohorts of obese pa.ients. NSM ca. be a.via.le surgica. option in ca.efully selected obese pa.ients a.d offer the a.va.ta.e of concea.ed sca.ring.

This study presents a.compa.a.ive a.a.ysis of two ima.e enha.cement techniques, Continuous Wa.elet Tra.sform (CWT) a.d Fa.t Fourier Tra.sform (FFT), in the context of improving the cla.ity of high-qua.ity 3D seismic da.a.obta.ned from the Ta.o Ba.in in West a.rica. Gha.a. The resea.ch focuses on a.compa.a.ive a.a.ysis of ima.e cla.ity in seismic a.tribute a.a.ysis to fa.ilita.e the identifica.ion of reservoir fea.ures within the subsurfa.e structures. The findings of the study indica.e tha. CWT ha. a.significa.t a.va.ta.e over FFT in terms of ima.e qua.ity a.d identifying subsurfa.e structures. The results demonstra.e the superior performa.ce of CWT in providing a.better representa.ion, ma.ing it more effective for seismic a.tribute a.a.ysis. The study highlights the importa.ce of choosing the a.propria.e ima.e enha.cement technique ba.ed on the specific a.plica.ion needs a.d the broa.er context of the study. While CWT provides high-qua.ity ima.es a.d superior performa.ce in identifying subsurfa.e structures, the selection between these methods should be ma.e judiciously, ta.ing into a.count the objectives of the study a.d the cha.a.teristics of the signa.s being a.a.yzed. The resea.ch provides va.ua.le insights into the decision-ma.ing process for selecting ima.e enha.cement techniques in seismic da.a.a.a.ysis, helping resea.chers a.d pra.titioners ma.e informed choices tha. ca.er to the unique requirements of their studies.
