Cloud-edge AI must jointly satisfy model compression and security under tight device budgets. While Tensor-Train Decomposition (TTD) shrinks on-device models, prior selective-encryption studies largely assume dense weights, leaving its practicality under TTD compression unclear. We present TT-SEAL, a selective-encryption framework for TT-decomposed networks. TT-SEAL ranks TT cores with a sensitivity-based importance metric, calibrates a one-time robustness threshold, and uses a value-DP optimizer to encrypt the minimum set of critical cores with AES. Under TTD-aware, transfer-based threat models (and on an FPGA-prototyped edge processor) TT-SEAL matches the robustness of full (black-box) encryption while encrypting as little as 4.89-15.92% of parameters across ResNet-18, MobileNetV2, and VGG-16, and drives the share of AES decryption in end-to-end latency to low single digits (e.g., 58% -> 2.76% on ResNet-18), enabling secure, low-latency edge AI.

Invisible watermarking is essential for tracing the provenance of digital content. However, training state-of-the-art models remains notoriously difficult, with current approaches often struggling to balance robustness against true imperceptibility. This work introduces Pixel Seal, which sets a new state-of-the-art for image and video watermarking. We first identify three fundamental issues of existing methods: (i) the reliance on proxy perceptual losses such as MSE and LPIPS that fail to mimic human perception and result in visible watermark artifacts; (ii) the optimization instability caused by conflicting objectives, which necessitates exhaustive hyperparameter tuning; and (iii) reduced robustness and imperceptibility of watermarks when scaling models to high-resolution images and videos. To overcome these issues, we first propose an adversarial-only training paradigm that eliminates unreliable pixel-wise imperceptibility losses. Second, we introduce a three-stage training schedule that stabilizes convergence by decoupling robustness and imperceptibility. Third, we address the resolution gap via high-resolution adaptation, employing JND-based attenuation and training-time inference simulation to eliminate upscaling artifacts. We thoroughly evaluate the robustness and imperceptibility of Pixel Seal on different image types and across a wide range of transformations, and show clear improvements over the state-of-the-art. We finally demonstrate that the model efficiently adapts to video via temporal watermark pooling, positioning Pixel Seal as a practical and scalable solution for reliable provenance in real-world image and video settings.

The digitisation campaigns carried out by libraries and archives in recent years have facilitated access to documents in their collections. However, exploring and exploiting these documents remain difficult tasks due to the sheer quantity of documents available for consultation. In this article, we show how the semantic annotation of the textual content of study corpora of archival documents allow to facilitate their exploitation and valorisation. First, we present a methodological framework for the construction of new interfaces based on textual semantics, then address the current technological obstacles and their potential solutions. We conclude by presenting a practical case of the application of this framework.

Verification and validation of autonomous driving (AD) systems and components is of increasing importance, as such technology increases in real-world prevalence. Safety-critical scenario generation is a key approach to robustify AD policies through closed-loop training. However, existing approaches for scenario generation rely on simplistic objectives, resulting in overly-aggressive or non-reactive adversarial behaviors. To generate diverse adversarial yet realistic scenarios, we propose SEAL, a scenario perturbation approach which leverages learned objective functions and adversarial, human-like skills. SEAL-perturbed scenarios are more realistic than SOTA baselines, leading to improved ego task success across real-world, in-distribution, and out-of-distribution scenarios, of more than 20%. To facilitate future research, we release our code and tools: https://github.com/cmubig/SEAL

Integrated population models (IPMs) are a promising approach to test ecological theories and assess wildlife populations in dynamic and uncertain conditions. By combining multiple data sources into a unified model, they enable the parametrization of versatile, mechanistic models that can predict population dynamics in novel circumstances. Here, we present a Bayesian IPM for the ringed seal (Pusa hispida botnica) population inhabiting the Bothnian Bay in the Baltic Sea. Despite the availability of long-term monitoring data, traditional assessment methods have faltered due to dynamic environmental conditions, varying reproductive rates, and the recently re-introduced hunting, thus limiting the quality of information available to managers. We fit our model to census and various demographic, reproductive, and harvest data from 1988 to 2023 to provide a comprehensive assessment of past population trends, and predict population response to alternative hunting scenarios. We estimated that 20,000 to 36,000 ringed seals inhabited the Bothnian Bay in 2024, increasing at a rate of 3% to 6% per year. Reproductive rates have increased since 1988, leading to a substantial increase in the growth rate up until 2015. However, the re-introduction of hunting has since reduced the growth rate, and even minor quota increases are likely to reduce it further. Our results also support the hypothesis that a greater proportion of the population hauls out under lower ice cover circumstances, leading to higher aerial survey results in such years. In general, our study demonstrates the value of IPMs for monitoring wildlife populations under changing environments, and supporting science-based management decisions.

Digital libraries oftentimes provide access to historical newspaper archives via keyword-based search. Historical figures and their roles are particularly interesting cognitive access points in historical research. Structuring and clustering news articles would allow more sophisticated access for users to explore such information. However, real-world limitations such as the lack of training data, licensing restrictions and non-English text with OCR errors make the composition of such a system difficult and cost-intensive in practice. In this work we tackle these issues with the showcase of the National Library of the Netherlands by introducing a role-based interface that structures news articles on historical persons. In-depth, component-wise evaluations and interviews with domain experts highlighted our prototype's effectiveness and appropriateness for a real-world digital library collection.

Egodokumenty w pracowniczych aktach osobowych: osobowość – mentalność – świat wartości. Na przykładzie wybranych materiałów archiwalnych z XX w. Akta osobowe są dokumentami, gromadzonymi przez aktotwórców, w których odbija się przede wszystkim przebieg drogi zawodowej w poszczególnych miejscach pracy. Źródła, które wystąpiły w badanych aktach, trak-towane są jako egodokumenty, gdyż autor dokumentu opowiada w nich sobie. Zachowane dokumenty mogą posłużyć do tworzenia biogramów, analizy faktów historycznych poszczególnych osób, podawać informacje o otaczającym ich świecie, czy też pomagać przy wyjaśnianiu różnych złożonych procesów ekonomicznych, socjologicznych itp. Niniejszy artykuł ma na celu spojrzenie na akta osobowe z perspektywy badań antropologicznych, które w pewien sposób pomagają w poznaniu człowieka, jego doznań i sposobie pojmowania rzeczywistości.Materiały archiwalne zostały wytypowane przy wykorzystaniu metody reprezentacyjnej. Użyto próby losowej polegającej na wyborze przypadkowych elementów z zamkniętego zbioru generalnego. W omawianym badaniu populacją generalną były akta osobowe pracowników Magistratu Miejskiego w Bydgoszczy z okresu międzywojennego oraz akta osobowe członków i podopiecznych Związku Bojowników o Wolność i Demokrację Zarząd Wojewódzki w Bydgoszczy.Wybrane jednostki służyły pogłębionej analizie egodokumentalnej, której celem było poznanie świata wartości bohatera. Czy jednak każdy życiorys czy rozbudowane podanie daje nam podstawy do prześledzenia go właśnie pod kątem osobowości człowieka? Czy daje wystarczająco dużo materiału do przeprowadzenia badań? Czy źródła zakwalifikowane do egodokumentów rzeczywiście są nimi? Na te pytania stara się odpowiedzieć tekst artykułu.

Memento aggregators enable users to query multiple web archives for captures of a URI in time through a single HTTP endpoint. While this one-to-many access point is useful for researchers and end-users, aggregators are in a position to provide additional functionality to end-users beyond black box style aggregation. This paper identifies the state-of-the-art of Memento aggregation, abstracts its processes, highlights shortcomings, and offers systematic enhancements.

Menurut Undang-Undang Nomor 43 Tahun 2009 tentang Kearsipan, penyusutan arsip adalah kegiatan pengurangan jumlah arsip dengan cara memindahkan arsip inaktif dari unit pengolah ke unit kearsipan, memusnahkan arsip yang tidak memiliki nilai guna, dan menyerahkan arsip statis kepada lembaga kearsipan. Dalam setiap tahapannya (pindah, musnah, serah) diperlukan daftar arsip. Saat arsip sudah menjadi inaktif, maka arsip tersebut harus dibuatkan daftar arsip inaktif sekurang-kurangnya kolom mengacu pada Pasal 44 Peraturan Pemerintah Nomor 28 Tahun 2012. Penelitian ini bertujuan untuk memaparkan tingkat efisiensi, kemudahan penelusuran arsip, dan pemonitoran penyusutan arsip dengan mengembangkan daftar arsip inaktif existing melalui penambahan kolom sesuai kebutuhan untuk penyusutan arsip di Departemen Manajemen. Penelitian ini dilakukan dengan menggunakan pendekatan kualitatif dengan metode deskriptif. Data diperoleh melalui observasi, wawancara, penyebaran kuesioner, dan dokumentasi. Hasil penelitian pengembangan daftar arsip inaktif meliputi pengelolaan arsip dan ketersediaan SDM kearsipan, implementasi peraturan kearsipan, penataan arsip inaktif dan layanan, pengembangan daftar arsip inaktif, dan implementasi dan layanan. Daftar arsip inaktif existing hanya sebagai sarana temu balik arsip, tidak dapat memonitor penyusutan arsip tahap berikutnya. Pengembangan daftar arsip inaktif digunakan sebagai sarana temu balik arsip sekaligus dapat memonitoring penyusutan arsip, meningkatkan efektivitas dan efisiensi pekerjaan.

A importância da informação para o desenvolvimento social é indiscutível. A partir do século XX passou a ser de importância fundamental para o desenvolvimento da sociedade pós-industrial e pós-moderna. Dessa forma, o acesso a esse bem constitui direito de todos, inclusive das pessoas com deficiência, que lutam, historicamente pelos seus direitos fundamentais, luta essa ratificada pela Organização das Nações Unidas, em 2008, na Convenção dos Direitos da Pessoa com Deficiência. Sendo a informação um direito de todos, esse direito inclui também a pessoa com deficiência e que as bibliotecas universitárias devem empreender ações mediadoras que garantam o acesso igualitário à informação por parte dos usuários com deficiência no âmbito do Sistema Universitário de Bibliotecas (SIBI) da Universidade Federal da Bahia (UFBA). Com o objetivo de conhecer as condições de acessibilidade física e informacional nessas bibliotecas, visando a construção do Projeto Bibliotecas Acessíveis do SIBI/UFBA, realizou-se a presente pesquisa, com a aplicação do questionário “Consulta sobre Acessibilidade nas Bibliotecas do SIBI/UFBA”, utilizando a ferramenta Google Forms, para conhecer as condições de adequação física, acervos e equipamentos existentes, além de obter um diagnóstico sobre a qualidade do atendimento ofertado nas bibliotecas. Os resultados revelaram a precariedade da estrutura física e informacional existente na maioria das bibliotecas, demonstrando a necessidade de se promover melhorias substanciais na adequação de espaços, oferta de equipamentos e acervos específicos que permitam a prestação de um atendimento de qualidade que atenda às necessidades informacionais da comunidade de pessoas com deficiência na UFBA e da sociedade em geral.

Prior work on web archive profiling were focused on Archival Holdings to describe what is present in an archive. This work defines and explores Archival Voids to establish a means to represent portions of URI spaces that are not present in a web archive. Archival Holdings and Archival Voids profiles can work independently or as complements to each other to maximize the Accuracy of Memento Aggregators. We discuss various sources of truth that can be used to create Archival Voids profiles. We use access logs from Arquivo.pt to create various Archival Voids profiles and analyze them against our MemGator access logs for evaluation. We find that we could have avoided more than 8% of additional False Positives on top of the 60% Accuracy we got from profiling Archival Holdings in our prior work, if Arquivo.pt were to provide an Archival Voids profile based on URIs that were requested hundreds of times and never returned any success responses.

We present a framework for web-scale archiving of the dark web. While commonly associated with illicit and illegal activity, the dark web provides a way to privately access web information. This is a valuable and socially beneficial tool to global citizens, such as those wishing to access information while under oppressive political regimes that work to limit information availability. However, little institutional archiving is performed on the dark web (limited to the Archive.is dark web presence, a page-at-a-time archiver). We use surface web tools, techniques, and procedures (TTPs) and adapt them for archiving the dark web. We demonstrate the viability of our framework in a proof-of-concept and narrowly scoped prototype, implemented with the following lightly adapted open source tools: the Brozzler crawler for capture, WARC file for storage, and pywb for replay. Using these tools, we demonstrate the viability of modified surface web archiving TTPs for archiving the dark web.
