On the Fragility of Alfvén waves in a Stratified Atmosphere [PDF]
Complete asymptotic expansions are developed for slow, Alfv\'en and fast magnetohydrodynamic waves at the base of an isothermal three-dimensional (3D) plane stratified atmosphere. Together with existing convergent Frobenius series solutions about $z=\infty$, matchings are numerically calculated that illuminate the fates of slow and Alfv\'en waves ...

Vega-MT: The JD Explore Academy Translation System for WMT22 [PDF]
We describe the JD Explore Academy's submission of the WMT 2022 shared general translation task. We participated in all high-resource tracks and one medium-resource track, including Chinese-English, German-English, Czech-English, Russian-English, and Japanese-English.

Does the Alfvén wave disrupt the large-scale magnetic cloud structure? [PDF]
Alfv\'en waves are primal and pervasive in space plasmas and significantly contributes to microscale fluctuations in the solar wind and some heliospheric processes. Here, we demonstrate the first observable distinct feature of Alfv\'en wave while propagating from magnetic cloud to trailing solar wind.

A stylized fact on the Mexico's mandate revocation 2022 that remains the 2006 presidential elections/ Un hecho estilizado en la revocación de mandato en México que recuerda las presidenciales de 2006 [PDF]
Vote processes are the results of several complex interactions which are hard to separate in order to understand its role in the final result. The revocatory exercise performed in Mexico in 2022 allows an approximation to the Mexican dynamics of vote.

Attention Link: An Efficient Attention-Based Low Resource Machine Translation Architecture [PDF]
Transformers have achieved great success in machine translation, but transformer-based NMT models often require millions of bilingual parallel corpus for training. In this paper, we propose a novel architecture named as attention link (AL) to help improve transformer models' performance, especially in low training resources.

Code-Mixed Sentiment Analysis Using Machine Learning and Neural Network Approaches [PDF]
Sentiment Analysis for Indian Languages (SAIL)-Code Mixed tools contest aimed at identifying the sentence level sentiment polarity of the code-mixed dataset of Indian languages pairs (Hi-En, Ben-Hi-En). Hi-En dataset is henceforth referred to as HI-EN and Ben-Hi-En dataset as BN-EN respectively. For this, we submitted four models for sentiment analysis

Ethereum Name Service: the Good, the Bad, and the Ugly [PDF]
DNS has always been criticized for its inherent design flaws, making the system vulnerable to kinds of attacks. Besides, DNS domain names are not fully controlled by the users, which can be easily taken down by the authorities and registrars. Since blockchain has its unique properties like immutability and decentralization, it seems to be promising to ...

Optimizing Pricing, Repositioning, En-Route Time, and Idle Time in Ride-Hailing Systems [PDF]
In ride-hailing systems, en-route time refers to the time that elapses from the moment a car is dispatched to pick up a rider until the rider is picked up. A fundamental phenomenon in ride-hailing systems is that there is a trade-off between en-route time and the time that a car waits for a dispatch. In short, if cars spend little time idle waiting for

Cohomologie des fibrés en droites sur les compactifications des groupes réductifs [PDF]
On s'int\'eresse aux compactifications \'equivariantes d'un groupe r\'eductif quelconque, $G$, vu comme espace homog\`ene pour $G \times G$. Pour un rev\^etement fini $\widetilde{G}$ de $G$, les groupes de cohomologie des fibr\'es en droites sur ces compactifications sont naturellement des $\widetilde{G} \times \widetilde{G}-$modules de dimension finie.
