BACKGROUND It has yet to be determined whether the language of dyspnea responds to pulmonary rehabilitation programs (PRP). OBJECTIVE We tested the hypothesis that PRP affect both the intensity and quality of exercise-induced dyspnea in patients with chronic obstructive pulmonary disease (COPD). METHODS We studied 49 patients equipped with a portable telemetric spiroergometry device during ...

In this paper, we deal with the inverse spectral problem for the equation −(pu′)′ + qu = λρu on a finite interval (0, h). We give some uniqueness results on q and ρ from the Gelfand spectral data, when the coefficients p and ρ are piecewise Lipschitz and q is bounded. We also prove an equivalence result between the Gelfand spectral data and the Borg–Levinson spectral data. As a consequence, we ...

The study determined physiological and psychophysical responses to fire fighters' typical activities. Self-reported assessment of the most demanding fire fighting/rescue tasks were collected with a questionnaire. Then 19 voluntary fire fighters performed 3 simulated fire fighting/rescue tasks in protective clothing. Heart rate (HR), blood pressure and energy expenditure were measured; the ratin...

Borg-type uniqueness theorems for matrix-valued Jacobi operators H and supersymmetric Dirac difference operators D are proved. More precisely, assuming reflectionless matrix coefficients A,B in the self-adjoint Jacobi operator H = AS + AS + B (with S the right/left shift operators on the lattice Z) and the spectrum of H to be a compact interval [E−, E+], E− < E+, we prove that A and B are certa...

This study contributes a stochastic, multi-objective adaptation of the classic environmental economics Lake Problem as a computationally simple but mathematically challenging benchmarking problem. The Lake Problem considers a hypothetical town by a lake, which hopes to maximize its economic benefit without crossing a nonlinear, and potentially irreversible, pollution threshold. Optimization obj...

BACKGROUND Bronchial challenge tests are used to evaluate bronchial responsiveness in diagnosis and follow-up of asthmatic patients. Challenge induced cough has increasingly been recognized as a valuable diagnostic tool. Various stimuli and protocols have been employed. The aim of this study was to compare cough and dyspnea intensity induced by different stimuli. METHODS Twenty asthmatic pati...

Subjective rating is one of the alternatives to quantify hand force exertion. The rating of the Borg CR-10 scale has been used to quantify the perception of physical exertion. An experiment was conducted to test the grip force of male subjects at subjective ratings on the CR-10 scale under hand-posture conditions. It was found that the subjects applied a higher grip force than they perceived at...

This investigation examined the validity of newly developed Adult OMNI Elliptical Ergometer Ratings of Perceived Exertion Scales. 60 men and women performed a graded exercise test on an elliptical ergometer. Oxygen consumption (VO2), heart rate (HR), and ratings of perceived exertion were recorded at each stage from the Borg 15 Category scale and two different OMNI scales. One scale employed an...

Of all the villains populating the Star Trek universe, none is perhaps more terrifying and threatening than the Borg. First introduced in “Q Who,” the sixteenth episode of the second season of Star Trek: The Next Generation, this collective of cybernetic organisms quickly became “the signature villains for The Next Generation and Voyager eras of Star Trek” (Wikipedia). Unlike any previous or su...
