Transition‐Metal Catalysis and Organocatalysis: Where Can Progress Be Expected?

Foreign body aspiration: where can it be?

Fig. 1. Computed (CT) tomography showed migration of the pin into the descending aorta with the result of hemothorax. The pin was extracted via left thoracotomy by pulling out from the part of needle which was out of the aorta, immediately after CT evaluation. Fig. 2. Computed tomography showed migration of the pin outside the left main bronchus into mediastinum 1 cm distal to the carina. The p...

Suicide: where can help be found?

Spatially-oriented attention can be biased towards an expected dimension 1 Spatial attention can be biased towards an expected dimension RUNNING HEAD: Spatial attention and expected dimension

A commonly held view in both exogenous and endogenous orienting is that spatial attention is associated with enhanced processing of all stimuli at the attended location. However, we often search for a specific target at a particular location, so an observer should be able to jointly specify the target identity and expected location. Whether attention can bias dimension-specific processes at a p...

Lifestyle modifications and erectile dysfunction: what can be expected?

Erectile dysfunction (ED) is a common medical disorder whose prevalence is increasing worldwide. Modifiable risk factors for ED include smoking, lack of physical activity, wrong diets, overweight or obesity, metabolic syndrome, and excessive alcohol consumption. Quite interestingly, all these metabolic conditions are strongly associated with a pro-inflammatory state that results in endothelial ...

What can be expected from a Boolean derivative?

Several concepts of a Boolean derivative have been investigated in the literature. In this paper we find out whether a Boolean operator can satisfy all of the three basic derivative-like properties: additivity, homogeneity and the Leibniz rule. In a certain sense, the answer is negative. The attempts to establish Boolean analogues of several concepts and results from Calculus begun in 1917 with...
