Efficient reallocation of indivisible resources: Pair-efficiency versus Pareto-efficiency
In the object reallocation problem, achieving Pareto-efficiency is desirable, but may be too demanding for implementation purposes. In contrast, pair-efficiency, which is the minimal efficiency requirement, is more suitable. Despite being a significant relaxation, however, pair-efficiency ensures Pareto-efficiency for any strategy-proof and individually rational rule when agents' preferences are unrestricted. What if agents' preferences have specific restricted structures, such as single-peak…

Generalmajor setzt auf mehr Effizienz bei ukrainischer Luftverteidigung
Der deutsche Generalmajor Christian Freuding setzt angesichts der massiven Drohnenangriffe Russlands auf mehr Effizienz in der Luftverteidigung der Ukraine. Im Bundeswehr-Format "Nachgefragt" verwies er darauf, dass Russland seine Produktionskapazitäten weiter erhöhe und die Drohnenangriffe nochmals ausweiten wolle. Ziel der Russen sei es, 2.000 Drohnen g…

MECHA: Multithreaded and Efficient Cryptographic Hardware Access
This paper presents a multithread and efficient cryptographic hardware access (MECHA) for efficient and fast cryptographic operations that eliminates the need for context switching. Utilizing a UNIX domain socket, MECHA manages multiple requests from multiple applications simultaneously, resulting in faster processing and improved efficiency. We comprise several key components, including the Server thread, Client thread, Transceiver thread, and a pair of Sender and Receiver queues. MECHA design…

At this year's Berlin Buzzwords, join Evgeniya Sukhodolskaya as she presents miniCOIL—a novel approach to creating a sparse neural retrieval model. This model aims to combine the advantages of dense and lexical retrieval methods while avoiding their drawbacks. Evgeniya will explain how to design and train a lightweight model that performs well on out-of-domain data and will demonstrate its capabilities.

High-Efficiency Quantum Memory of Full-Bandwidth Squeezed Light
In continuous-variable quantum information processing, it is crucial to develop high-efficiency and broadband quantum memory of squeezed light, which enables the storage of full-bandwidth information. Here, we present a quantum memory of squeezed light with up to 24 MHz bandwidth, which is at least 12 times that of previous narrowband resonant memory systems, via a far-off resonant Raman process. We achieve output squeezing of as high as 1.0 dB with fidelity above 92% and a memory efficiency of…
