The fundamental equation of asset pricing states that the expected timeand risk-adjusted cumulative return on any asset equals one at all horizons. This paper shows that for a typical asset, the realized timeand risk-adjusted cumulative return tends to zero with probability one. Just two assumptions are required: limited liability and no arbitrage. This apparent paradox is resolved by a further...

Let T be the quasi-nilpotent DT-operator. By use of Voiculescu’s amalgamated R-transform we compute the momets of (T −λ1)∗(T − λ1) where λ ∈ C, and the Brown-measure of T + √ Y , where Y is a circular element ∗-free from T for > 0. Moreover we give a new proof of Śniady’s formula for the moments τ(((T ∗)kT )) for k, n ∈ N.

Neglected patella tendon ruptures require reconstruction using tendon grafts. The LARS ligament has been successfully used in cruciate and collateral knee ligament reconstruction. We present a technique using LARS ligament for the reconstruction of a chronic patella tendon rupture in a low-demand patient. The result after 1-year follow-up was deemed successful.

Background: Early impairment of the cognitive and behavioral executive processes are found in Mild Cognitive Impairment (MCI) as well as in Alzheimer’s disease (AD). These processes are strongly linked to autonomy in daily living because they are involved in our adaptation to many new situations.Objectives and methods: To evaluate the executive processes and their links with autonomy, we compar...

OBJECTIVE Near-infrared spectroscopy (NIRS) is a noninvasive technique that allows monitoring of regional hemoglobin oxygen saturation (rSO2) values and might have a role in the diagnosis of peripheral arterial disease. We assessed the reproducibility and inter-subject variability of rSO2 values and rSO2 limb-to-arm ratios (LARs) in lower extremities of healthy subjects. METHODS The rSO2 valu...

Aim Little is known about the pathophysiology of low anterior resection syndrome (LARS), and evidence concerning management patients diagnosed with this condition scarce. The aim LARS Expert Advisory Panel was to develop practical guidance for healthcare professionals dealing LARS. Method ‘Management guidelines syndrome’ (MANUEL) project promoted by a team eight experts in assessment After face...

We propose the elastic net, a new regularization and variable selection method. Real world data and a simulation study show that the elastic net often outperforms the lasso, while enjoying a similar sparsity of representation. In addition, the elastic net encourages a grouping effect, where strongly correlated predictors tend to be in or out of the model together.The elastic net is particularly...
