Landing in Japan without mobile data can make a long travel day much harder than it needs to be. The minute you arrive you'll likely rely on your phone for train routes, maps, translation, reservations, and messages, so it's best to sort out getting connected before your flight. I've lived in Japan for nearly a decade, both in cities and the countryside, and I've used several different ways to stay connected. These days, I've found an eSIM to be the easiest option. But there are a few things worth checking before you buy one.

This work introduces Clipout, a method for removing a target concept in pretrained text-to-image models. By randomly clipping units from the learned data embedding and using a contrastive objective, models are encouraged to differentiate these clipped embedding vectors.

A major Verizon outage appeared to impact customers across the United States starting around noon ET on Wednesday. Calls to Verizon customers from other carriers may also be impacted. Customers of the telecom giant Verizon began reporting cellular outages around the United States beginning around noon ET on Wednesday, saying they could not complete calls and did not have access to mobile data. Verizon broadband internet customers are also reporting issues. AT&T and T-Mobile customers also began reporting service outages in the same timeframe, however these reports may be linked to the Verizon outage.

Abstract--Decentralized finance (DeFi) is experiencing rapid expansion. However, prevalent code reuse and limited open-source contributions have introduced significant challenges to the blockchain ecosystem, including plagiarism and the propagation of vulnerable code. Consequently, an effective and accurate similarity detection method for EVM bytecode is urgently needed to identify similar contracts. Traditional binary similarity detection methods are typically based on instruction stream or control flow graph (CFG), which have limitations on EVM bytecode due to specific features like low-level EVM bytecode and heavily-reused basic blocks. Moreover, the highly-diverse Solidity Compiler (Solc) versions further complicate accurate similarity detection. Motivated by these challenges, we propose a novel EVM bytecode representation called Stable-Semantic Graph (SSG), which captures relationships between "stable instructions" (special instructions identified by our study). Moreover, we implement a prototype, Esim, which embeds SSG into matrices for similarity detection using a heterogeneous graph neural network. Esim demonstrates high accuracy in SSG construction, achieving F1-scores of 100% for control flow and 95.16% for data flow, and its similarity detection performance reaches 96.3% AUC, surpassing traditional approaches. Our large-scale study, analyzing 2,675,573 smart contracts on six EVM-compatible chains over a one-year period, also demonstrates that Esim outperforms the SOT A tool Etherscan in vulnerability search. With the rapid expansion of decentralized finance (DeFi) in the blockchain ecosystem, DeFi projects, which are built on smart contracts on the Ethereum Virtual Machine (EVM), have attracted substantial investment in recent years, with over $88.8 billion Total V alue Locked (TVL) in 2024 [1]. As a representative case, the Compound v2 protocol [3], one of the top lending protocols, has been widely adopted and forked by numerous DeFi projects. This protocol has a known precision loss issue that can be exploited when the corresponding market lacks liquidity. Since 2022, a series of attacks (e.g., Hundred Finance Attack [4], Onyx Protocol Attack [5], Radiant Attack [6]) have been observed due to the code abuse of Compound v2 protocol, resulting in millions of dollars in losses. Consequently, there is an urgent need for an efficient method to detect code reuse in EVM bytecode (binaries), a process also known as EVM bytecode similarity detection. More than 99% of the Ethereum contracts are not open source [2] In general, binary similarity detection studies in traditional languages (e.g., C++ [7], [8], [9] and Java [10]) can be divided into two categories, i.e., instruction stream based and control flow graph (CFG) based.

We study the problem of incorporating prior knowledge into a deep Transformer-based model,i.e.,Bidirectional Encoder Representations from Transformers (BERT), to enhance its performance on semantic textual matching tasks. By probing and analyzing what BERT has already known when solving this task, we obtain better understanding of what task-specific knowledge BERT needs the most and where it is most needed. The analysis further motivates us to take a different approach than most existing works. Instead of using prior knowledge to create a new training task for fine-tuning BERT, we directly inject knowledge into BERT's multi-head attention mechanism. This leads us to a simple yet effective approach that enjoys fast training stage as it saves the model from training on additional data or tasks other than the main task. Extensive experiments demonstrate that the proposed knowledge-enhanced BERT is able to consistently improve semantic textual matching performance over the original BERT model, and the performance benefit is most salient when training data is scarce.

In both the consumer and business worlds, technology is constantly and rapidly evolving. Unique and innovative new business, health and consumer technologies are emerging every day, but sometimes it takes a little time for the "next big thing" to get recognized and catch on. Google, for instance, launched the original iteration of G-Suite back in 2006--long before the cloud computing and real-time collaboration became the standard. As leaders in the tech field, the members of Forbes Technology Council are always on the lookout for emerging devices, programs and systems that could revolutionize their industry--even if the tech is still in its early phases. We asked a group of them to share the most impressive piece of tech from the last three years that most people aren't aware of yet.

Event cameras are revolutionary sensors that work radically differently from standard cameras. Instead of capturing intensity images at a fixed rate, event cameras measure changes of intensity asynchronously, in the form of a stream of events, which encode per-pixel brightness changes. In the last few years, their outstanding properties (asynchronous sensing, no motion blur, high dynamic range) have led to exciting vision applications, with very low-latency and high robustness. However, these sensors are still scarce and expensive to get, slowing down progress. To address this issue, we present ESIM: an efficient event camera simulator implemented in C and available open source.

This paper presents a new deep learning architecture for Natural Language Inference (NLI). Firstly, we introduce a new architecture where alignment pairs are compared, compressed and then propagated to upper layers for enhanced representation learning. Secondly, we adopt factorization layers for efficient and expressive compression of alignment vectors into scalar features, which are then used to augment the base word representations. The design of our approach is aimed to be conceptually simple, compact and yet powerful. We conduct experiments on three popular benchmarks, SNLI, MultiNLI and SciTail, achieving competitive performance on all. A lightweight parameterization of our model also enjoys a $\approx 3$ times reduction in parameter size compared to the existing state-of-the-art models, e.g., ESIM and DIIN, while maintaining competitive performance. Additionally, visual analysis shows that our propagated features are highly interpretable.

The Fact Extraction and VERification (FEVER) shared task was launched to support the development of systems able to verify claims by extracting supporting or refuting facts from raw text. The shared task organizers provide a large-scale dataset for the consecutive steps involved in claim verification, in particular, document retrieval, fact extraction, and claim classification. In this paper, we present our claim verification pipeline approach, which, according to the preliminary results, scored third in the shared task, out of 23 competing systems. For the document retrieval, we implemented a new entity linking approach. In order to be able to rank candidate facts and classify a claim on the basis of several selected facts, we introduce two extensions to the Enhanced LSTM (ESIM).
