The isotopic composition of U in nature is generally assumed to be invariant. Here, we report variations of the U/U isotope ratio in natural samples (basalts, granites, seawater, corals, black shales, suboxic sediments, ferromanganese crusts/ nodules and BIFs) of 1.3‰, exceeding by far the analytical precision of our method ( 0.06‰, 2SD). U isotopes were analyzed with MC-ICP-MS using a mixed U–...

As deep learning algorithms are widely adopted, an increasing number of them positioned in embedded application domains with strict reliability constraints. The expenditure significant resources to satisfy performance requirements neural network accelerators has thinned out the margins for delivering safety applications, thus precluding adoption conventional fault tolerance methods. potential e...

We present a dynamic network rewiring (DNR) method to generate pruned deep neural (DNN) models that both are robust against adversarially generated images and maintain high accuracy on clean images. In particular, the disclosed DNR training is based unified constrained optimization formulation using novel hybrid loss function merges sparse learning with adversarial training. This strategy dynam...

میون‌­ها به دلیل سطح مقطع کوچک برای انجام واکنش، متداول‌­ترین تابش فضایی قابل آشکارسازی در زمین هستند. همانند سایر ذراتی که از طریق برخورد ذرات پرانرژی تولید می‌­شوند، ناپایدار و دارای طیف توزیع طول عمر این مقاله، انرژی میون با استفاده سیستم طیف‌­سنجی دیجیتال اندازه‌­گیری شده است. روش ارایه همه ماژول­ه‌ای الکترونیک هسته‌­ای آنالوگ حذف فرایند شکل­ دهی سیگنال‌­ها ثبت آن­ها صورت نرم­‌افزاری اندازه...

Heterogeneous computing systems (HCSs), which consist of various processing elements (PEs) that vary in their ability, are usually facilitated by the network-on-chip (NoC) to interconnect its components. The emerging point-to-point NoCs support single-cycle-multi-hop transmission, reduce or eliminate latency dependence on distance, addressing scalability concern raised high for long-distance tr...
