Comparison of carcinogen, carbon monoxide, and ultrafine particle emissions from narghile waterpipe and cigarette smoking

Sheheitli, Hiba; Jaroudi, Ezzat; Saleh, Rawad; Daher, Nancy; Badr, Therese; Sepetdjian, Elizabeth; Al Rashidi, Mariam; Saliba, Najat; Shihadeh, Alan (2017-09-28)

The lack of scientific evidence on the constituents, properties, and health effects of second-hand waterpipe smoke has fueled controversy over whether public smoking bans should include the waterpipe. The purpose of this ...
Dynamics of a mass–spring–pendulum system with vastly different frequencies

Sheheitli, Hiba; Rand, Richard H. (2017-09-28)

We investigate the dynamics of a simple pendulum coupled to a horizontal mass–spring system. The spring is assumed to have a very large stiffness value such that the natural frequency of the mass–spring oscillator, when ...
Dynamics of three coupled limit cycle oscillators with vastly different frequencies

Sheheitli, Hiba; Rand, Richard H. (2017-09-28)

A system of three coupled limit cycle oscillators with vastly different frequencies is studied. The three oscillators, when uncoupled, have the frequencies ω1=O(1), ω2=O(1/ε) and ω3=O(1/ε2), respectively, where ε≪1. The ...
On the dynamics of a spinning top under high-frequency excitation

Sheheitli, Hiba (2018-02-07)

We investigate the dynamics of a spinning top whose pivot point undergoes a small amplitude high-frequency vertical vibration. The method of Direct Partition of Motion is used to obtain an autonomous equation governing the ...
On the dynamics of a spinning top under high-frequency excitation.

Sheheitli, Hiba (2018-02-07)

We investigate the dynamics of a spinning top whose pivot point undergoes a small-amplitude high-frequency horizontal vibration. The method of direct partition of motion is used to obtain an autonomous two-degree-of-freedom ...
On the dynamics of systems with vastly different frequencies

Sheheitli, Hiba (Cornell University, 2018-02-07)

The method of direct partition of motion (DPM) has been widely used to study the dynamics of non-autonomous oscillatory systems subject to external high frequency excitation. In this work, we explore the non-trivial dynamics ...
Origin of arrhythmias in a heart model

Sheheitli, Hiba; Rand, Richard (2017-09-28)

An investigation of the nonlinear dynamics of a heart model is presented. The model compartmentalizes the heart into one part that beats autonomously (the x oscillator), representing the pacemaker or SA node, and a second ...
Role of myosin II in motility and in force generation of DRG growth cones

Sheheitli, Hiba; Sayyad, Wasim Amin; Erika, Ercolini; Ban, Jelena; Amin, Ladan; Fabris, Paolo; Valbuena, Alejandro; Torre, Vincent (2017-09-28)
