Significant contribution of subseafloor microparticles to the global manganese budget
Nature Communications, 2019 Ferromanganese minerals are abundant in marine environments but the extent of these minerals in subseafloor sediments remains unknown. Here the authors find abundant ferromanganese microparticles in oxic pelagic clays, accounting for 14–16% of the new ...

Half-infinite sampling and its FT [PDF]
arXiv, 2021 In the digital world, signals are discrete and finite. The Fourier representation of discrete and finite signals is FT convolution of the finite sampling function and the continuous signal. Conventionally, finite sampling is treated as a segment of infinite sampling.

Masked Generative Modeling with Enhanced Sampling Scheme [PDF]
arXiv, 2023 This paper presents a novel sampling scheme for masked non-autoregressive generative modeling. We identify the limitations of TimeVQVAE, MaskGIT, and Token-Critic in their sampling processes, and propose Enhanced Sampling Scheme (ESS) to overcome these limitations. ESS explicitly ensures both sample diversity and fidelity, and consists of three stages:

Channel Capacity under General Nonuniform Sampling [PDF]
, 2012 This paper develops the fundamental capacity limits of a sampled analog channel under a sub-Nyquist sampling rate constraint. In particular, we derive the capacity of sampled analog channels over a general class of time-preserving sampling methods including irregular nonuniform sampling. Our results indicate that the optimal sampling structures extract

Rethinking Samples Selection for Contrastive Learning: Mining of Potential Samples [PDF]
arXiv, 2023 Contrastive learning predicts whether two images belong to the same category by training a model to make their feature representations as close or as far away as possible. In this paper, we rethink how to mine samples in contrastive learning, unlike other methods, our approach is more comprehensive, taking into account both positive and negative ...

FEBS Letters, EarlyView.Metabolic dysfunction‐associated steatotic liver disease (MASLD) affects nearly one‐third of the global population and poses a significant risk of progression to cirrhosis or liver cancer. Here, we discuss the roles of hepatic dendritic cell subtypes in MASLD, highlighting their distinct contributions to disease initiation and progression, and their ...

Overpowered: American domination, democracy and the ethics of energy consumption [PDF]
, 2006 The United States has used its overwhelming political and economic power to secure for itself a disproportionate share of the world’s non-renewable energy resources, most of which are located outside of our borders.

Diphthamide synthesis is linked to the eEF2‐client chaperone machinery
FEBS Letters, EarlyView.The diphthamide modification of eukaryotic translation elongation factor 2 (eEF2) is important for accurate protein synthesis. We addressed the potential coordination of de novo eEF2 synthesis with simultaneous or subsequent diphthamide modification. Our work reveals that the co‐chaperones Hgh1 and Cpr7, which are known to support folding of nascent ...

Designing for Truth in Counterfactual Games [PDF]
, 2020 This paper brings together two distinct and seemingly irreconcilable threads: first, the place of interactive narratives and games within the broader context of documentary media; and second, the value of counterfactual narrative as a documentary form. I
