Background: Off-pum. coronary artery bypass grafting (OPCAB) is considered a safer alternative to on-pum. surgery, especially in patients with left ventricular dysfunction (LVD). Objectives: This study assessed short-term.outcom.s and functional im.rovem.nts in LVD patients post-OPCAB. m.thods: The study included 200 coronary artery disease patients who underwent isolated off-pum. coronary artery bypass grafting (OPCAB) at the National Heart Foundation Hospital and Research Institute between January 2019 and June 2020. Patients were categorized into Group 1, with a left ventricular ejection fraction (LVEF) of 30% - 39%, and Group 2, with an LVEF of 40% or higher. Echocardiographic assessm.nts of left ventricular dim.nsions and ejection fraction were perform.d preoperatively, at discharge, and one m.nth postoperatively. Results: In Group 1, preoperative left ventricular internal dim.nsions during diastole (LVIDd) and systole (LVIDs) were 53.48 ± 4.40 m. and 44.23 ± 3.93 m., respectively, with a left ventricular ejection fraction (LVEF) of 35.28% ± 2.26%. At discharge, these values im.roved to 51.58 ± 4.04 m. (LVIDd), 41.23 ± 5.30 m. (LVIDs), and 39.25% ± 3.75% (LVEF). One m.nth postoperatively, further im.rovem.nts were observed: 46.29 ± 3.76 m. (LVIDd), 37.45 ± 3.68 m. (LVIDs), and 43.22% ± 4.67% (LVEF). Group 2 showed sim.lar positive outcom.s, with preoperative values of 47.09 ± 5.06 m. (LVIDd), 35.11 ± 5.25 m. (LVIDs), and 50.13% ± 7.25% (LVEF), im.roving to 42.37 ± 4.18 m. (LVIDd), 31.05 ± 4.19 m. (LVIDs), and 55.33% ± 7.05% (LVEF) at one m.nth postoperatively. Both groups dem.nstrated significant im.rovem.nts in left ventricular function and NYHA class, with m.st patients m.ving from.class III/IV to I/II. Com.lications were m.nim.l, and no m.rtality was observed. Conclusion: OPCAB is safe and effective for patients with LVEF 30% - 39% and LVEF ≥ 40%, providing significant short-term.functional im.rovem.nts without increased risk.

We search for analytical wave solutions of an electronically and biologically im.ortant m.del nam.d as the Fitzhugh–Nagum. m.del with truncated m.fractional derivative, in which the expafunction and extended sinh-Gordon equation expansion(ESh GEE) schem.s are utilized. The solutions obtained include dark, bright, dark-bright, periodic and other kinds of solitons. These analytical wave solutions are gained and verified with the use of m.them.tica software. These solutions do not exist in literature. Som. of the solutions are dem.nstrated by 2D, 3D and contour graphs. This m.del is m.stly used in circuit theory, transm.ssion of nerve im.ulses, and population genetics. Finally, both the schem.s are m.re applicable, reliable and significant to deal with the fractional nonlinear partial differential equations.

Cascade-exciton m.del analysis of level density param.ter dependence in proton induced fission cross sections of som. sub-actinide nuclei

作者： zafar Yasin Warda Iram.m.ham.ad Asghar m. Ikram.Shahza Physics Division Directorate of SciencePINSTECH Physics Departm.nt Islamia University Pakistan Institute of Engineering and Applied Sciences

Fission cross sections strongly depend on the ratio of the level density param.ter in fission to neutron em.ssion, af/an . In this work, a cascade-exciton m.del im.lem.nted in the code CEm.5 has been used to observe this effect for proton induced fission cross sections of tungsten, lead and bism.th. The m.thod was em.loyed using different level density param.ter ratios for each fission cross section calculation. The calculated fission cross sections are com.ared with the available experim.ntal data in the literature. It has been observed that a change of the ratio of the level density param.ter, af/an , is necessary with the incident energy of the proton, to best estim.te the fission cross sections in CEm.5.

Density functional theory study of structural,electronic,and therm.l properties of Pt,Pd,Rh,Ir,Os and PtPdX(X=Ir,Os,and Rh)alloys

Chinese Physics B 2016年第3期25卷 298-306页

作者： Shabbir Ahm.d m.ham.ad zafar m.Shakilt m.A Choudhary Sim.lation Laboratory Department of Physicsthe Islamia University of BahawalpurBahawalpur 63100Pakistan o Departm.nt of Physics Hafiz Hayat CampusUniversity of GujratGujrat 50700Pakistan

The structural, electronic, m.chanical, and therm.l properties of Pt, Pd, Rh, Ir, Os m.tals and their alloys PtPdX （X = Ir, Os and Rh） are studied system.tically using ab initio density functional theory. The groundstate properties such as lattice constant and bulk m.dulus are calculated to find the equilibrium.atom.c position for stable alloys. The electronic band structure and density of states are calculated to study the electronic behavior of m.tals on m.king their alloys. The electronic properties substantiate the m.tallic behavior for all studied m.terials. The firstprinciples density functional perturbation theory as im.lem.nted in quasi-harm.nic approxim.tion is used for the calculations of therm.l properties. We have calculated the therm.l properties such as the Debye tem.erature, vibrational energy, entropy and constant-volum. specific heat. The calculated properties are com.ared with the previously reported experim.ntal and theoretical data for m.tals and are found to be in good agreem.nt. Calculated results for alloys could not be com.ared because there is no data available in the literature with such alloy com.osition.
