The "over-nonlocal" formulation, where the weight for the nonlocal value is greater than unity and the excesses compensated by assigning a negative weight to the local value, is able to fully regularize certain material models when standard nonlocal enhancement fails to do so.
However, such criticisms on moral bio-enhancement fail to consider, according to Kahane and Savulescu, that this is "not at all an argument against enhancement but, rather, an argument for more precisely fine-tuned enhancement" ([ 12]: in press).
Third, over-expression of DLK1 (using its endogenous regulatory elements) in transgenic mice resulted in growth enhancement but the mice failed to survive early life and showed no signs of muscle hypertrophy [41].
In general, most of the contrast enhancement techniques fail to produce satisfactory results for diversified images such as dark, low-contrast, bright, mostly dark, high-contrast, mostly bright ones.
Another feature of this device that needs some improvement is the reproducibility of enhancement: out of the 20 devices that were tested, 2 failed to enhance fully.
It is not clear why we failed to observe enhancement of signaling or growth in tumors by the antibodies, and it is possible in the MMTV-Wnt1 model that Wnt signaling levels are already maximal.
A recent efficacy trial in South African infants failed to demonstrate enhancement of protection over BCG alone.
In contrast, our assays failed to prove enhancement of ROS on 4HPR-treated normal and activated peripheral lymphocytes (data not shown).
Hippocampal lesions significantly enhanced acquisition of the simultaneous discriminations in Experiments 1 and 2. Importantly, in Experiment 1 the significant enhancement caused by hippocampal lesions failed to interact with the training condition (i.e., Constant or Inconstant).
The questions of optimal scheduling have been addressed in limited studies combining radiotherapy with a number of anti-angiogenic agents (Williams et al, 2004; Dings et al, 2007; Shibuya et al, 2007) A study using concomitant PTK787/ZK222584 failed to show enhancement over radiotherapy alone, and study results showed that drug therapy after irradiation was optimal (Zips et al, 2005).
