The benefits of a hybrid‐3DEnVar data assimilation scheme for the convection‐permitting NWP model AROME–Austria

Quarterly Journal of the Royal Meteorological Society, EarlyView.
The climatological‐error covariance matrix used in three‐dimensional variational data assimilation (3DVar) provides smooth and isotropic increments spread to long distances. In contrast, three‐dimensional ensemble variational data assimilation (3DEnVar) with a purely ensemble‐error covariance matrix provides inhomogeneous increments and contains the ...

Information Bottleneck for a Rayleigh Fading MIMO Channel with an Oblivious Relay

Information, 2021
This paper considers the information bottleneck (IB) problem of a Rayleigh fading multiple-input multiple-out (MIMO) channel with an oblivious relay. The relay is constrained to operating without knowledge of the codebooks, i.e., it performs oblivious ...

When private set intersection meets big data : an efficient and scalable protocol

, 2013
Large scale data processing brings new challenges to the design of privacy-preserving protocols: how to meet the increasing requirements of speed and throughput of modern applications, and how to scale up smoothly when data being protected is big ...

Resource reallocation across successive systemic innovations: How Rolls‐Royce shaped the evolution of the turbojet, turboprop, and turbofan

Strategic Management Journal, EarlyView.
Abstract Research Summary Despite the importance of resource reallocation in shaping a variety of strategic outcomes, strategy scholars have paid only limited attention to the processes by which firms reallocate their resources across successive systemic innovations.

Oblivious Data Structures [PDF]

Proceedings of the 2014 ACM SIGSAC Conference on Computer and Communications Security, 2014
We design novel, asymptotically more efficient data structures and algorithms for programs whose data access patterns exhibit some degree of predictability. To this end, we propose two novel techniques, a pointer-based technique and a locality-based technique.

What Program for Love in the 21st Century? Thinking With and Beyond Luhmann

Systems Research and Behavioral Science, EarlyView.
ABSTRACT From a sociological perspective, the paper examines how normative frameworks for intimate relationships have changed since the publication of Luhmann's Love as Passion (1982). Building on Luhmann's notion of a program for love, we discuss his claim that late 20th century love semantics were organized around a program of understanding. We argue

Endemic Oblivious Transfer [PDF]

, 2021
Oblivious Transfer has played a crucial role in the design of secure multi party computation. Nevertheless, there are not many practical solutions that achieve simulation based security and at the same time instantiable based on different assumptions ...

Illuhmannating Technological Innovation Systems: Towards a Systems Perspective

Systems Research and Behavioral Science, EarlyView.
ABSTRACT The Technological Innovation Systems framework operates from an economic perspective, investigating the generation, diffusion and utilization of a specific technology within a particular institutional infrastructure. Emerging from innovation sciences, the TIS framework inherited methodological individualism as the micro‐level approach to ...

Breaking barriers in two-party quantum cryptography via stochastic semidefinite programming [PDF]

Quantum
In the last two decades, there has been much effort in finding secure protocols for two-party cryptographic tasks. It has since been discovered that even with quantum mechanics, many such protocols are limited in their security promises. In this work, we

The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

Structural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...
