When size is not important any more
Wireless phone companies, especially with number portability, sell a product that is less and less different, that is to say, a commodity. That is the reason scale economies play a very important role in this market. Given that it is not possible to make a large margin on the service that they offer, companies must focus their strategies on saving costs. Moreover, the more clients a company has...
متن کاملWhen is vestibular information important during walking?
Locomotion relies on vision, somatosensory input, and vestibular information. Both vision and somatosensory signals have been shown to be phase dependently modulated during locomotion; however, the regulation of vestibular information has not been investigated in humans. By delivering galvanic vestibular stimulation (GVS) to subjects at either heel contact, mid-stance, or toe-off, it was possib...
متن کاملBrain function - not size - is important
Some incidental findings on cranial imaging may render every one speechless. Brain plasticity in childhood and slow expansion of arachnoid cyst may be possible explanations of the discordance between the clinical and radiological findings. Here, we presented an asymptomatic, incidentally detected arachnoid cyst accompanied by compression of most parts of brain, displacing the motor cortex to th...
متن کاملImaging liver metastases—size is important
All metastases start out small, and treatment is more likely to be effective if the disease is detected at an early stage, so the current focus of imaging is to improve our ability to find small lesions. Sixty years ago, the most effective instrument for detecting liver metastases was the surgeon’s hand during laparotomy. J C Goligher, a former colleague in Leeds, followed up about 700 patients...
متن کاملWhen every $P$-flat ideal is flat
In this paper, we study the class of rings in which every $P$-flat ideal is flat and which will be called $PFF$-rings. In particular, Von Neumann regular rings, hereditary rings, semi-hereditary ring, PID and arithmetical rings are examples of $PFF$-rings. In the context domain, this notion coincide with Pr"{u}fer domain. We provide necessary and sufficient conditions for...
