MME: A Comprehensive Evaluation Benchmark for Multimodal Large Language Models
Multimodal Large Language Model (MLLM) relies on the powerful LLM to perform
multimodal tasks, showing amazing emergent abilities in recent studies, such as
writing poems based on an image. However, it is difficult for these case
studies to fully reflect the performance of MLLM, lacking a comprehensive
evaluation. In this paper, we fill in this blank, presenting the first MLLM
Evaluation benchmark MME. It measures both perception and cognition abilities
on a total of 14 subtasks. In order to avoid data leakage that may arise from
direct use of public datasets for evaluation, the annotations of
instruction-answer pairs are all manually designed. The concise instruction
design allows us to fairly compare MLLMs, instead of struggling in prompt
engineering. Besides, with such an instruction, we can also easily carry out
quantitative statistics. A total of 10 advanced MLLMs are comprehensively
evaluated on our MME, which not only suggests that existing MLLMs still have a
large room for improvement, but also reveals the potential directions for the
subsequent model optimization.Comment: https://github.com/BradyFU/Awesome-Multimodal-Large-Language-Model
Polygonatum cyrtonema polysaccharides reshape the gut microbiota to ameliorate dextran sodium sulfate-induced ulcerative colitis in mice
Ulcerative colitis (UC) is a chronic inflammatory bowel disease characterized inflammatory imbalance, intestinal epithelial mucosal damage, and dysbiosis of the gut microbiota. Polygonatum cyrtonema polysaccharides (PCPs) can regulate gut microbiota and inflammation. Here, the different doses of PCPs were administered to dextran sodium sulfate-induced UC mice, and the effects of the whole PCPs were compared with those of the fractionated fractions PCP-1 (19.9Â kDa) and PCP-2 (71.6 and 4.2Â kDa). Additionally, an antibiotic cocktail was administered to UC mice to deplete the gut microbiota, and PCPs were subsequently administered to elucidate the potential role of the gut microbiota in these mice. The results revealed that PCP treatment significantly optimized the lost weight and shortened colon, restored the balance of inflammation, mitigated oxidative stress, and restored intestinal epithelial mucosal damage. And, the PCPs exhibited superior efficacy in ameliorating these symptoms compared with PCP-1 and PCP-2. However, depletion of the gut microbiota diminished the therapeutic effects of PCPs in UC mice. Furthermore, fecal transplantation from PCP-treated UC mice to new UC-afflicted mice produced therapeutic effects similar to PCP treatment. So, PCPs significantly ameliorated the symptoms, inflammation, oxidative stress, and intestinal mucosal damage in UC mice, and gut microbiota partially mediated these effects
A Challenger to GPT-4V? Early Explorations of Gemini in Visual Expertise
The surge of interest towards Multi-modal Large Language Models (MLLMs),
e.g., GPT-4V(ision) from OpenAI, has marked a significant trend in both
academia and industry. They endow Large Language Models (LLMs) with powerful
capabilities in visual understanding, enabling them to tackle diverse
multi-modal tasks. Very recently, Google released Gemini, its newest and most
capable MLLM built from the ground up for multi-modality. In light of the
superior reasoning capabilities, can Gemini challenge GPT-4V's leading position
in multi-modal learning? In this paper, we present a preliminary exploration of
Gemini Pro's visual understanding proficiency, which comprehensively covers
four domains: fundamental perception, advanced cognition, challenging vision
tasks, and various expert capacities. We compare Gemini Pro with the
state-of-the-art GPT-4V to evaluate its upper limits, along with the latest
open-sourced MLLM, Sphinx, which reveals the gap between manual efforts and
black-box systems. The qualitative samples indicate that, while GPT-4V and
Gemini showcase different answering styles and preferences, they can exhibit
comparable visual reasoning capabilities, and Sphinx still trails behind them
concerning domain generalizability. Specifically, GPT-4V tends to elaborate
detailed explanations and intermediate steps, and Gemini prefers to output a
direct and concise answer. The quantitative evaluation on the popular MME
benchmark also demonstrates the potential of Gemini to be a strong challenger
to GPT-4V. Our early investigation of Gemini also observes some common issues
of MLLMs, indicating that there still remains a considerable distance towards
artificial general intelligence. Our project for tracking the progress of MLLM

Generation and Analysis of a Large-Scale Expressed Sequence Tag Database from a Full-Length Enriched cDNA Library of Developing Leaves of <i>Gossypium hirsutum</i> L
<div><p>Background</p><p>Cotton (<i>Gossypium hirsutum</i> L.) is one of the world’s most economically-important crops. However, its entire genome has not been sequenced, and limited resources are available in GenBank for understanding the molecular mechanisms underlying leaf development and senescence.</p><p>Methodology/Principal Findings</p><p>In this study, 9,874 high-quality ESTs were generated from a normalized, full-length cDNA library derived from pooled RNA isolated from throughout leaf development during the plant blooming stage. After clustering and assembly of these ESTs, 5,191 unique sequences, representative 1,652 contigs and 3,539 singletons, were obtained. The average unique sequence length was 682 bp. Annotation of these unique sequences revealed that 84.4% showed significant homology to sequences in the NCBI non-redundant protein database, and 57.3% had significant hits to known proteins in the Swiss-Prot database. Comparative analysis indicated that our library added 2,400 ESTs and 991 unique sequences to those known for cotton. The unigenes were functionally characterized by gene ontology annotation. We identified 1,339 and 200 unigenes as potential leaf senescence-related genes and transcription factors, respectively. Moreover, nine genes related to leaf senescence and eleven MYB transcription factors were randomly selected for quantitative real-time PCR (qRT-PCR), which revealed that these genes were regulated differentially during senescence. The qRT-PCR for three <i>GhYLSs</i> revealed that these genes express express preferentially in senescent leaves.</p><p>Conclusions/Significance</p><p>These EST resources will provide valuable sequence information for gene expression profiling analyses and functional genomics studies to elucidate their roles, as well as for studying the mechanisms of leaf development and senescence in cotton and discovering candidate genes related to important agronomic traits of cotton. These data will also facilitate future whole-genome sequence assembly and annotation in <i>G. hirsutum</i> and comparative genomics among <i>Gossypium</i> species.</p></div

Arginine vasopressin in hypothalamic paraventricular nucleus is transferred to the nucleus raphe magnus to participate in pain modulation
abstract: Hypothalamic paraventricular nucleus (PVN) is one of the main sources of arginine vasopressin (AVP) synthesis and secretion. AVP is the most important bioactive substance in PVN regulating pain process. Our pervious study has pointed that pain stimulation induced AVP increase in the nucleus raphe magnus (NRM), which plays a role in pain modulation. The present study was designed to investigate the source of AVP in the rat NRM during pain process using the methods of nucleus push–pull perfusion and radioimmunoassay. The results showed that pain stimulation increased the AVP concentration in the NRM perfusion liquid, PVN cauterization inhibited the role that pain stimulation induced the increase of AVP concentration in the NRM perfusion liquid, and PVN microinjection of l-glutamate sodium, which excited the PVN neurons, could increase the AVP concentration in the NRM perfusion liquid. The data suggested that AVP in the PVN might be transferred to the NRM to participate in pain modulation
