Length of sick leave as a risk marker of hip fracture: a nationwide cohort study from Sweden

Sickness absence is a risk marker for future health outcomes, but no previous studies have examined its association with osteoporotic fractures in old age. The results of this prospective population-based coho...

Obesity and muscle strength as long-term determinants of all-cause mortality—a 33-year follow-up of the Mini-Finland Health Examination Survey

To examine the independent and combined associations of obesity and muscle strength with mortality in adult men and women.

Fall-related risk factors and heel quantitative ultrasound in the assessment of hip fracture risk: a 10-year follow-up of a nationally representative adult population sample

Maximal walking speed and quantitative ultrasound index (QUI) were significant and independent predictors of hip fracture among subjects aged ≥55 years. A model including readily available variables along with...

Are body mass index, waist circumference and waist-to-hip ratio associated with leptin in 90-year-old people?

Data on how body mass index (BMI), waist circumference (WC) and waist-to-hip ratio (WHR) are associated with body fat in the oldest-old people are scarce. The purpose of this study was to examine if BMI, WC or...

Association of midlife obesity and cardiovascular risk with old age frailty: a 26-year follow-up of initially healthy men

To investigate whether old age frailty is predicted by midlife overweight/obesity and cardiovascular disease (CVD) risk.

Effect of age on the association between body fat percentage and maximal walking speed

To study the effect of age on the association between body fat percentage and maximal walking speed in older people.

Inertial and gravitational mass in quantum mechanics

We show that in complete agreement with classical mechanics, the dynamics of any quantum mechanical wave packet in a linear gravitational potential involves the gravitational and the inertial mass only as their r...

The effect of obesity combined with low muscle strength on decline in mobility in older persons: results from the InCHIANTI Study

Both obesity and muscle impairment are increasingly prevalent among older persons and negatively affect health and physical functioning. However, the combined effect of coexisting obesity and muscle impairment...

Transient dynamics of linear quantum amplifiers

The transient dynamics of a quantum linear amplifier during the transition from dam** to amplification regime is studied. The master equation for the quantized mode of the field is solved, and the solution ...

Transition Steering via Space-Dependent Coupling

The transition between electronic energy surfaces of molecules is usually described in the Franck-Condon approximation where the spatial variation of the coupling matrix elements is neglected. In this work we ...

On Correlation Approach to Scattering in the Decoherence Timescale

We provide a “first principles” description of scattering from open quantum systems subject to a Lindblad-type dynamics. In particular we consider the case that the duration of the scattering process is of sim...

Quantum Dynamics Effected by Repeated Measurements

We consider the time evolution of a dynamic quantum system coupled to a repeatedly measured ancilla. Given the time lapse Δt between two subsequent measurements, the combined system may be described using a diffe...

The Varieties of Master Equations

Irreversible time evolution is in quantum systems described by Master Equations. These are usually derived by elimination of degrees of freedom belonging to an environment acting as a reservoir. When the reser...

Coherent control of the self-trap** transition

We discuss the dynamics of two weakly coupled Bose-Einstein condensates in a double-well potential, contrasting the mean-field picture to the exact N-particle evolution. On the mean-field level, a self-trap** t...
