Um monitor de computador numa sala escura é uma ótima armadilha anti-mosquitos.
O problema: depois de esborrachar os mosquitos é preciso limpš-lo.

(Bicycle) Speed and safety
For years I've heard people talking about how motor-assisted bicycles "are safer" because they can "match traffic speed", but I think this is mistaken.  Here's three reasons why. For me the most compelling reason comes from a 2007 paper by Laurie F. Beck, Ann M. Dellinger, and Mary E. O’Neil in the American Journal of Epidemiology, "Motor Vehicle Crash Injury Rates by Mode of Travel, United States: Using Exposure-Based Methods…

Framework of a multiscale data-driven digital twin of the muscle-skeletal system
Musculoskeletal disorders (MSDs) are a leading cause of disability worldwide, requiring advanced diagnostic and therapeutic tools for personalised assessment and treatment. Effective management of MSDs involves the interaction of heterogeneous data sources, making the Digital Twin (DT) paradigm a valuable option. This paper introduces the Musculoskeletal Digital Twin (MS-DT), a novel framework that integrates multiscale biomechanical data with computational modelling to create a detailed, patie…

Optimal Execution Strategies Incorporating Internal Liquidity Through Market Making
This paper introduces a new algorithmic execution model that integrates interbank limit and market orders with internal liquidity generated through market making. Based on the Cartea et al.\cite{cartea2015algorithmic} framework, we incorporate market impact in interbank orders while excluding it for internal market-making transactions. Our model aims to optimize the balance between interbank and internal liquidity, reducing market impact and improving execution efficiency.

Zerrow: True Zero-Copy Arrow Pipelines in Bauplan
Bauplan is a FaaS-based lakehouse specifically built for data pipelines: its execution engine uses Apache Arrow for data passing between the nodes in the DAG. While Arrow is known as the "zero copy format", in practice, limited Linux kernel support for shared memory makes it difficult to avoid copying entirely. In this work, we introduce several new techniques to eliminate nearly all copying from pipelines: in particular, we implement a new kernel module that performs de-anonymization, thus eli…

Adaptive and Efficient Dynamic Memory Management for Hardware Enclaves
The second version of Intel Software Guard Extensions (Intel SGX), or SGX2, adds dynamic management of enclave memory and threads. The first version required the address space and thread counts to be fixed before execution. The Enclave Dynamic Memory Management (EDMM) feature of SGX2 has the potential to lower launch times and overall execution time. Despite reducing the enclave loading time by 28--93%, straightforward EDMM adoption strategies actually slow execution time down by as much as 58%…

vNV-Heap: An Ownership-Based Virtually Non-Volatile Heap for Embedded Systems
The Internet of Batteryless Things might revolutionize our understanding of connected devices by harvesting required operational energy from the environment. These systems come with the system-software challenge that the intermittently powered IoT devices have to checkpoint their state in non-volatile memory to later resume with this state when sufficient energy is available. The scarce energy resources demand that only modified data is persisted before a power failure, which requires precise m…
