1. Arnold: An eFPGA-Augmented RISC-V SoC for Flexible and Low-Power IoT End Nodes 

   Schiavone P.D.; Rossi D.; Di Mauro A.; et al. (2021)

   IEEE Transactions on Very Large Scale Integration (VLSI) Systems

   A wide range of Internet of Things (IoT) applications require powerful, energy-efficient, and flexible end nodes to acquire data from multiple sources, process and distill the sensed data through near-sensor data analytics algorithms, and transmit it wirelessly. This work presents Arnold: A 0.5-To-0.8-V, 46.83-\mu \text{W} /MHz, 600-MOPS fully programmable RISC-V microcontroller unit (MCU) fabricated in 22-nm Globalfoundries GF22FDX ...

2. COMPARISON of THERMAL DECOMPOSITION and SEQUENTIAL DISSOLUTION-TWO SAMPLE PREPARATION METHODS for RADIOCARBON DATING of LIME MORTARS 

   Daugbjerg T.S.; Lindroos A.; Hajdas I.; et al. (2021)

   Radiocarbon

   Dating lime mortar samples using the radiocarbon (14C) method can be difficult. This is because the contamination is similar to the primary dating material (CaCO3) and consequently difficult to remove. Mortar can also have late-in-formation pyrogenic carbonate from interactions with the environment after the initial hardening phase, such as recrystallization, fire damage or delayed hardening. When 14C dating a system of primary dating ...

3. ¹⁴C INTERCOMPARISON EXERCISE on BONES and IVORY SAMPLES: IMPLICATIONS for FORENSICS 

   Quarta G.; Molnár M.; Hajdas I.; et al. (2021)

   Radiocarbon

   The application of accelerator mass spectrometry radiocarbon (AMS 14C) dating in forensics is made possible by the use of the large excursion of the 14C concentration in the post-WWII terrestrial atmosphere due to nuclear testing as a reference curve for data calibration. By this approach high-precision analyses are possible on samples younger than ∼70 years. Nevertheless, the routine, widespread application of the method in the practice ...

4. Moving Object Detection by 3D Flow Field Analysis 

   Jiang C.; Paudel D.P.; Fofi D.; et al. (2021)

   IEEE Transactions on Intelligent Transportation Systems

   Map-based localization and sensing are one of the key components in autonomous driving technologies, where high quality 3D map reconstruction is fundamentally utmost important. However, due to the highly dynamic and uncontrollable properties of real world environment, building a high quality 3D map is not straightforward and requires several strong assumptions. To address this challenge, we present a complete framework, which detects and ...

5. Topology in Shallow-Water Waves: A Violation of Bulk-Edge Correspondence 

   Graf G.M.; Jud H.; Tauber C. (2021)

   Communications in Mathematical Physics

   We study the two-dimensional rotating shallow-water model describing Earth’s oceanic layers. It is formally analogue to a Schrödinger equation where the tools from topological insulators are relevant. Once regularized at small scale by an odd-viscous term, such a model has a well-defined bulk topological index. However, in presence of a sharp boundary, the number of edge modes depends on the boundary condition, showing an explicit violation ...
