Nanoalloys (or alloy nanoparticles) are an important class of materials that are promising for their functional properties. However, designing synthesis protocols to control their structure and chemical ordering is rather challenging. Part of this difficulty stems from the lack of information on their metastable and stable structures. Here, we develop a general computational framework to construct a structural chart of nanoalloys using 38-atom AgCu nanoalloys as a model system. Initially, the equilibrium st

Abstract. We investigate how weather regimes influence surface precipitation and associated cloud microphysical processes at Dumont d’Urville (DDU; 66.7° S, 140.0° E) using data from the Antarctic Precipitation: Remote Sensing from Surface and Space (APRES3) project. Two precipitation-producing regimes, Summer Warm Air Advection (S-WAA) and Low-Pressure (Low-P), account for 94.2 % of total precipitation at DDU. Hydrometeor growth processes were analysed through comprehensive case studies of Low-P and S-WAA

In the 19th century, religious and political interest in Jerusalem led to a prolific production of maps depicting the city. Notably, none of the retrieved maps were created by local cartographers; early examples were often produced by individual travelers without formal cartographic training, and later by Western nations and organizations. Factors such as limited expertise, restricted local knowledge, and difficult accessibility resulted in significant inventions, omissions, and distortions. At the same tim

Vision-and-Language Navigation (VLN) tasks have gained prominence within artificial intelligence research due to their potential application in fields like home assistants. Many contemporary VLN approaches, while based on transformer architectures, have increasingly incorporated additional components such as external knowledge bases or map information to enhance performance. These additions, while boosting performance, also lead to larger models and increased computational costs. In this paper, to achieve b

The advancement of computational tools for cartometric analysis has opened new avenues for the identification and understanding of stemmatic relationships between historical maps through the analysis of their planimetric deformations. The 19th-century western cartographic depiction of Jerusalem serves as an exemplary case study in this context, since the difficulties in conducting comprehensive onsite surveys and the fascination towards the depiction of this area led to a proliferation of maps characterized

This paper investigates rural mobility in the Global South using a participatory GIS approach to address the lack of mobility data. Limited rural mobility due to poor infrastructure and financial constraints hinders social and economic activities, impeding development. The study aims to explore the socio-economic impacts of limited mobility, identify software needs for data-scarce environments, and map daily mobility patterns. Fieldwork was conducted in Kenya (2022) and Nepal (2023), collecting geographic d

Consensus protocol have seen increased usage in recent years due to the industry shift to distributed computing. However, it has traditionally been implemented in the application layer. We propose to move the consensus protocol in the transport layer, to offer reliable ordered delivery of messages to applications. Our implementation builds on R2P2, a novel RPC framework for datacenter applications. It can run both using Linux UDP sockets or kernel bypass using DPDK. We observe tail latency increase of only

This visualisation represents the research activity of the Digital Humanities Lab through publications and co-authorship. Vertical disposition is ordered by time: each layer is a different year of publications, from the lab’s foundation to nowadays. The layers displays the collaboration networks: two researchers are linked if they published together. The vertical trajectories represent the activity of a researcher through the time. The authors position is fix in the space. As consequence, the trajectories b

In this paper we define a scale-space for cortical mean curvature maps on the sphere, that offers a hierarchical representation of the cortical structures, useful in multi-scale algorithms. A spherical feature map is obtained through inflation of the cortical surface of one hemisphere. Using the Beltrami framework, we embed this spherical mesh in a higher dimensional space and the feature assigned to a mesh vertex becomes an additional component of its coordinates. This enhanced mesh then evolves under Belt

In this paper, we present Ishtar, a lightweight and versatile collection of software for remote data access and monitoring. The monitoring architecture is crucial during the development and experimentation of autonomous systems like Micro Air Vehicles. Ishtar comprises a flexible communication layer that allows enumeration, inspection and modification of data in the remote system. The protocol is designed to be robust to the data loss and corruption that typically arises with small autonomous system, while

Failure restoration at the IP layer in IP-over-WDM networks requires to map the IP topology on the WDM topology in such a way that a failure at the WDM layer leaves the IP topology connected. Such a mapping is called survivable. Finding a survivable mapping is known to be NP-complete, making it impossible in practice to assess the existence or absence of such a mapping for large networks. (i) We first introduce a new concept of piecewise survivability, which makes the problem much easier, and allows us to f

Mobile ad-hoc networking works properly only if the participating nodes cooperate in routing and forwarding. However, it may be advantageous for individual nodes not to cooperate. We propose a protocol, called CONFIDANT, for making misbehavior unattractive; it is based on selective altruism and utilitarianism. It aims at detecting and isolating misbehaving nodes, thus making it unattractive to deny cooperation. Trust relationships and routing decisions are based on experienced, observed, or reported routing

Cartography is one of the major application areas using geographical databases. Whether it is for the business of producing paper maps for sale, or whether it is for displaying maps on a screen to visualize the result of a query, we need computer systems that know how to represent the same geographical area at different scales. The concept of multiscale database has become popular in the GIS domain as a way to enforce consistency between representations and reduce the global update load. Scaling, however, i

This paper discusses the problem of reliable communication in large scale networks. More precisely, we describe the problem of {\it non-transitive} communication in a large scale distributed system due to link failure which leads to {\it partial} partitions. A definition for {\it partial} partition in contrast to a {\it total} partition is given. The solution to mask these {\it partial} partitions and as a consequence providing {\it transitive} communication, consists in using every possible site in the dis
