1 Introduction Organic solar cells (OSCs) are attracting significant interest for their advantages of being light, flexible, semi-transparent, and Roll-to-Roll (R2R) fabrication compatible.[1-4] Moreover, the development of non-fullerene acceptors has led to a significant increase in the power conversion efficiency (PCE) of single-junction OSCs, with the newest PCE exceeding 20.2%.[5] Flexible organic solar cells (FOSCs) have great potential for applications in wearable devices, the Internet...

AbstractComputational methods should be accurate and robust for tasks in biology and medicine, especially when facing different types of attacks, defined as perturbations of benign data that can cause a significant drop in method performance. Therefore, there is a need for robust models that can defend attacks. In this manuscript, we propose a novel framework named RobustCell to analyze attack-defense methods in single-cell and spatial transcriptomic data analysis.

AbstractVarious Foundation Models (FMs) have been built based on the pre-training and fine-tuning framework to analyze single-cell data with different degrees of success. In this manuscript, we propose a method named scELMo (Single-cell Embedding from Language Models), to analyze single-cell data that utilizes Large Language Models (LLMs) as a generator for both the description of metadata information and the embeddings for such descriptions.

AbstractDrug synergy prediction is a challenging and important task in the treatment of complex diseases including cancer. In this manuscript, we present a novel Foundation Model, known as BAITSAO, for tasks related to drug synergy prediction with a unified pipeline to handle different datasets. We construct the training datasets for BAITSAO based on the context-enriched embeddings from Large Language Models for the initial representation of drugs and cell lines.

AbstractCharacterizing cell activities within a spatially resolved context is essential to enhance our understanding of spatially-induced cellular states and features. While single-cell RNA-seq (scRNA-seq) offers comprehensive profiling of cells within a tissue, it fails to capture spatial context.

Coherent pumping of magnons by light in an optomagnonic cavity has been recently reported. Here we propose and model the Bose-Einstein condensation of magnons pumped by a coherent pumping source in an optical cavity composed of a ferromagnetic waveguide. To stabilize the condensation, a large number of ±k-magnon pairs should be pumped into the cavity. We calculate and analyze the methods of direct pumping and indirect pumping by multiple confined optical modes.
