Transfer Learning and Permutation‐Invariance Improving Predicting Genome‐Wide, Cell‐Specific and Directional Interventions Effects of Complex Systems

Advanced Science, EarlyView.
SETComp, a transfer learning model based on permutation‐invariance, is pre‐trained on single‐compound intervention data and fine‐tuned on complex system (e.g., natural products) data. The model achieves up to 93.86% accuracy on complex system‐cell‐gene association predictions, outperforming the baseline by up to 27.59%.

Unveiling Novel Viral Diversity, Biogeography, and Host Networks in Wildlife Through High‐Throughput Sequencing Data Mining

Advanced Science, EarlyView.
Analysis of 57 536 high‐throughput sequencing datasets uncovers a vast, hidden world of viruses in wildlife. The researchers reveal significant geographic and host‐specific patterns of viruses, and their surprising cross‐species transmissions, such as avian flu viruses infecting goats.

Highly Efficient Discovery of 3D Mechanical Metamaterials via Monte Carlo Tree Search

Advanced Science, EarlyView.
Machine learning (ML), as a data‐driven method, has revolutionized metamaterial design, surpassing traditional intuition‐driven trial‐and‐error methods in both efficiency and performance. Here, MCTS‐AL, an active learning framework integrating finite element simulation (FEM), convolutional neural networks (CNNs), and Monte Carlo Tree Search (MCTS ...

Chagas vectors Panstrongylus chinai (Del Ponte, 1929) and Panstrongylus howardi (Neiva, 1911): chromatic forms or true species?

Parasites & Vectors, 2020
Background Chagas disease is a parasitic infection transmitted by “kissing bugs” (Hemiptera: Reduviidae: Triatominae) that has a huge economic impact in Latin American countries.

ReRAM/CMOS Array Integration and Characterization via Design of Experiments

Advanced Electronic Materials, EarlyView.
This paper proposes the Design of Experiments to characterize arrays of oxide‐based ReRAM devices by exploring the large characterization space efficiently using only a few numbers of experiments. Using in‐house integration of 20 000 ReRAM devices on a CMOS chip, the unconventional optimization approach determines optimized measurement parameters and ...

Non‐Tariff Measures and U.S. Agricultural Exports

Applied Economic Perspectives and Policy, EarlyView.
Abstract How much do non‐tariff measures (NTMs) affect U.S. agricultural exports? While countries maintain a large and diverse set of NTMs to safeguard the health of plants, animals, and humans, policymakers and regulatory bodies may neglect the impact these measures have on international trade.
