Abstract A swimmer embedded on an inertialess fluid must perform a non-reciprocal motion to swim forward. The archetypal demonstration of this unique motion-constraint was introduced by Purcell with the so-called “scallop theorem”. Scallop here is minimal mathematical model composed two arms connected via hinge whose periodic (of opening and closing its arms) not sufficient achieve net displace...

‎let $p(z)=z^s h(z)$ where $h(z)$ is a polynomial‎ ‎of degree at most $n-s$ having all its zeros in $|z|geq k$ or in $|z|leq k$‎. ‎in this paper we obtain some new results about the dependence of $|p(rz)|$ on $|p(rz)| $ for $r^2leq rrleq k^2$‎, ‎$k^2 leq rrleq r^2$ and for $rleq r leq k$‎. ‎our results refine and generalize certain well-known polynomial inequalities‎.

PURPOSE Biosimilars are a cost-effective alternative to biologics that could improve patients' access to expensive biological medicines. Currently, there are little data on doctors' perceptions of biosimilars and in what situations they are comfortable prescribing biosimilars. In this study, we investigated medical specialists' perceptions of biosimilars and the factors associated with the acce...

A new method for seismic design of structures with the aim controlling earthquake damage to a prescribed level is presented in this paper. The specified special moment frame buildings vertical and horizontal regularity. main idea determining story drift correlation selected index value. For purpose, Park-Ang correlated maximum drift. Through performing several nonlinear dynamic analyses steel r...

background : uncontrolled and irrational use of antibiotics increases the rate of antimicrobial resistance and treatment failure. compliance with antibiotics is an important indicator to show how patients use their prescribed drugs and it can explain the relationship between drug administration and treatment outcome that needs to be monitored and promoted. we decided to evaluate compliance to a...

rational prescribing increases the quality of health care and patient outcomes. in this study, the quality of drug prescription in specialist physicians in isfahan province of iran was assessed for evaluating the rational use of drugs and improving the therapeutic outcomes.this retrospective survey was conducted on a total of 7999530 prescriptions from all general and specialist physicians. the...

Abstract This paper develops a robust framework for the multiscale design of three-dimensional lattices with macroscopically tailored thermal and thermo-structural characteristics. A approach is implemented where discrete evaluations small-scale lattice unit cell characteristics are converted to response surface models so that properties exist as continuous functions micro-parameters. The deriv...

The isotropic thermoelasticity system of type-III, describing both the mechanical and thermal behaviours a body occupying bounded domain with Lipschitz boundary, is considered. displacement vector either normal heat flux or temperature are prescribed on boundary. Both theoretical numerical reconstructions time-dependent source from knowledge an additional weighted integral measurement investiga...

The paper is concerned with an optimal control problem governed by the rate-independent system of quasi-static perfect elasto-plasticity. objective optimize displacement field in domain occupied body means prescribed Dirichlet boundary data, which serve as variables. arising optimization nonsmooth for several reasons, particular, since control-to-state mapping not single-valued. We therefore ap...
