State-of-the-art sensors for measuring FPGA voltage fluctuations are timeto-digital converters (TDCs). They allow detecting voltage fluctuations in the order of a few nanoseconds. The key building component of a TDC is a delay line, typically implemented as a chain of fast carry propagation multiplexers. In FPGAs, the fast carry chains are constrained to dedicated logic and routing, and need to be routed strictly vertically. In this work, we present an alternative approach to designing on-chip voltage sensors, in which the FPGA routing resources replace the carry logic. We present three variants of what we name a routing delay sensor (RDS): one vertically constrained, one horizontally constrained, and one free of any constraints. We perform a thorough experimental evaluation on both the Sakura-X side-channel evaluation board and the Alveo U200 datacenter card, to evaluate the performance of the RDS sensors in the context of a remote power side-channel analysis attack. The results show that our best RDS implementation in most cases outperforms the TDC. On average, for breaking the full 128-bit key of an AES-128 cryptographic core, an adversary requires 35% fewer side-channel traces when using the RDS than when using the TDC. Besides making the attack more effective, given the absence of the placement and routing constraint, the RDS sensor is also easier to deploy.

The second issue of the Swiss Logistics Market Study in 2024 focuses on trends, sustainability, geopolitical crises and automation in the Swiss logistics market. The trend radar illustrates the current technological, social and economic trends in the Swiss logistics market and their dynamics. The focus of the analysis of developments in the freight transport market is on determining the sustainability of logistics. In addition, mode-specific developments in road, rail, air and shipping are examined in order to describe the current market situation. Besides the recurring static topics, the issue includes two dynamic topics, geopolitical crises and automation: the complexity along global trade routes is constantly increasing due to global crises. Established flows of goods have had to be adapted within a very short space of time, which is now leading to new challenges. Delays and cost increases in supply chains are the logical consequence. In this issue, we also explore the question of how much digitalisation actually makes sense. Could Switzerland be described as an Eldorado for automation in warehouse logistics? Issue 02-2024 of the Swiss Logistics Market Study provides answers to these and further questions.

Although the field of organizational unlearning has recently gained increased interest, its conceptual foundations and raison d’être are still debated. In this review, we aim to revisit various discourses and arguments to advance the understanding of organizational unlearning in management and organization studies. Using an integrative literature review approach with systematic elements, we examine the existing body of research on organizational unlearning. We review the literature from different perspectives, focusing on a process-based understanding in terms of why and how organizations intentionally discard knowledge. Based on our review, we develop an integrative framework that portrays organizational unlearning as a dynamically unfolding process over time. We propose implications and offer research directions that will allow future researchers to develop a more profound understanding of the concept.
