See detailQM7-X, a comprehensive dataset of quantum-mechanical properties spanning the chemical space of small organic molecules

We introduce QM7-X, a comprehensive dataset of 42 physicochemical properties for ≈4.2 million equilibrium and non-equilibrium structures of small organic molecules with up to seven non-hydrogen (C, N, O, S, Cl) atoms. To span this fundamentally important region of chemical compound space (CCS), QM7-X includes an exhaustive sampling of (meta-)stable equilibrium structures—comprised of constitutional/structural isomers and stereoisomers, e.g., enantiomers and diastereomers (including cis-/trans- and conformational isomers)—as well as 100 non-equilibrium structural variations thereof to reach a total of ≈4.2 million molecular structures. Computed at the tightly converged quantum-mechanical PBE0+MBD level of theory, QM7-X contains global (molecular) and local (atom-in-a-molecule) properties ranging from ground state quantities (such as atomization energies and dipole moments) to response quantities (such as polarizability tensors and dispersion coefficients). By providing a systematic, extensive, and tightly-converged dataset of quantum-mechanically computed physicochemical properties, we expect that QM7-X will play a critical role in the development of next-generation machine-learning based models for exploring greater swaths of CCS and performing in silico design of molecules with targeted properties.

We investigate the performances of the time-switching (TS) and power-splitting (PS) based energy harvesting models in a two-hop relay assisted network where the end-users are capable of decoding information and harvesting energy concurrently. In particular, we consider joint resource allocation and relay selection to realize Simultaneous Wireless Transmission of Information and Energy (Wi-TIE) in a multi-carrier multi-user cooperative system where the relays employ the amplify-and-forward (AF) protocol. First, we formulate based on the TS and PS Wi-TIE architectures an optimization problem to maximize the sum of energy harvested at the end-users, taking into consideration each user's quality-of-service (QoS) requirement as well as power constraints at the transmit and relaying nodes. We then solve the formulated problem to optimize the users' Wi-TIE splitting factors along with relay-user coupling, sub-carrier-user assignment, sub-carrier pairing, and power allocation. Finally, we demonstrate the benefits of the proposed framework via numerical results. [less ▲]

This work is about the design and configuration of service-oriented communication on top of Ethernet TSN. The first objective is to present takeaways from the design and implementation of the Renault E/E Service-Oriented Architecture (SOA) called FACE. In particular, we discuss technological, design and configuration choices made for the SOA, such as how to segment messages (UDP with multiple events, TCP, SOME/IP TP), and the technical possibilities to shape the transmission of the packets on the Ethernet network. The second objective is to study how to ensure the Quality of Service (QoS) required by services. Indeed, services introduce specific challenges, be it only the sheer amount of traffic they generate and if there is a growing body of experiences in the use of TSN QoS mechanisms most of what has been learned so far is mostly about meeting the requirements of individual streams. Less is known for services that involve the transmission of several, possibly segmented, messages with more complex transmission patterns. We show on the FACE architecture how SOME/IP messages were mapped to TSN QoS mechanisms in a manual then automated manner so as to meet the individual requirements of the services in terms of timing, and the system’s requirements in terms of memory usage.

Random numbers [1] are widely used in numerical computing, statistical simulation, random sampling, etc. The security of random numbers is getting more attention. In addition to random numbers, information and network environment security [2] are also very important in real life, such as the generation of verification code for login, QR code for online payment, etc. All random numbers that involve important identity information must have extremely high security to protect personal privacy from being leaked or illegally stolen. At present, the mechanism for generating random numbers by computers is at risk of being attacked which is subject that the generated random numbers may be predicted in some cases. Random number generation (RNG) [3] has always been one of the biggest problems. The problem with classic random number generators, i.e., pseudorandom number generators, consists in the possibility to know the deterministic process of pseudorandom generation by unwanted persons. This may result, in the case of cryptography, in compromising a myth of security. Another problem may be the incorrect handling of the generated sequence—mostly in cryptographic uses, the generated random sequence is applied once. Its multiple usage may lead to a security breach (e.g., in the case of the OTP cipher, a sufficiently long key should be truly random and used once in that protocol, otherwise it will be possible to break the code).

Bien que le Web ait seulement trente ans, son patrimoine est déjà pléthorique : la fondation Internet Archive a collecté plus de 345 milliards de pages web depuis 1996. Cette fondation, qui fut l’un des pionniers de l’archivage du Web, n’est pas seule à préserver et collecter aujourd’hui ce patrimoine dit « nativement numérique ». Au cours des années 2000, plusieurs pays ont en effet lancé de tels archivages, souvent confiés aux bibliothèques nationales, et cette tendance ne cesse de s’affirmer depuis. Ces initiatives introduisent des ruptures : dans la notion même d’archive, mais aussi dans les pratiques des professionnels des bibliothèques et du patrimoine, tout comme dans celles des chercheurs. Cet ouvrage se propose d’initier le lecteur aux enjeux humains et techniques de l’archivage de la Toile, de la collecte à l’analyse en passant par la création et le partage de corpus ou encore le cadre législatif. Il étudie de manière pragmatique cet archivage, en essayant de rendre palpable à la fois sa fabrique (technique, institutionnelle, juridique), la relation que ses acteurs entretiennent avec les publics et les évolutions qu’ont connues les collectes en une vingtaine d’années. Ce livre s’intéresse également à la manière dont les archives du Web, outre leur rôle patrimonial, peuvent aujourd’hui être exploitées par différents acteurs, notamment à des fins de recherche.
