There are no Barker arrays having more than two dimensions
Davis, Jedwab and Smith recently proved that there are no 2-dimensional Barker arrays except of size 2×2. We show that the existence of a (d+1)-dimensional Barker array implies the existence of a d-dimensional Barker array with the same number of ±1 elements. We deduce that there are no Barker arrays having more than two dimensions, as conjectured by Dymond in 1992.
متن کاملInternet-scale Chemical Sensing: Is It More than a Vision?∗
In order to realise scalability of chemical sensors in extensively deployed wireless sensor networks, considerable materials challenges must be overcome. Conventional devices are currently far too expensive and unreliable for massive long-term field deployment. Cost can be driven down by imaginative approaches to transduction and instrument design. For example, we have produced a complete instr...
متن کاملProject title (no more than 20 words)
The target basins of this project are located in the Mekong River Basin across the toposequence (northern Thailand, northeast Thailand, Mekong Delta in Vietnam). An additional site is located in Bhutan. In these basins, diverse stakeholders with differing perceptions of water dynamics adopt various strategies to cope with the problems. There is a need, therefore, to understand the factors influ...
متن کاملPI3K and mTOR inhibitor, NVP-BEZ235, is more toxic than X-rays in prostate cancer cells
Background: Radiotherapy and adjuvant androgen deprivation therapy have historically been the first treatment choices for prostate cancer but treatment resistance often limits the capacity to effectively manage the disease. Therefore, alternative therapeutic approaches are needed. Here, the efficacies of radiotherapy and targeting the pro-survival cell signaling components epidermal growth fact...
متن کاملp63 is more sensitive and specific than 34βE12 to differentiate adenocarcinoma of prostate from cancer mimickers
Objective(s): Prostate cancer is the world’s leading cause of cancer and the second cause of cancer-related death in men after lung cancer. Differentiation of prostate adenocarcinoma from benign prostate lesions and hyperplasia sometimes cannot be done on the basis of morphologic findings. Considering the fact that in the prostate adenocarcinoma there is no basal cell layer, basal cell markers ...
