Oracle bone inscriptions, the earliest known form of Chinese writing, hold immense historical and linguistic significance. However, existing digital datasets are typically limited to isolated characters and lack contextual and structural information essential for comprehensive analysis. We present the Oracle Bone Inscriptions Multi-modal Dataset (OBIMD), a large-scale, publicly available corpus to provide pixel-aligned rubbing and facsimile images, character-level annotations, and sentence-level transcriptions with corresponding reading sequences. OBIMD encompasses 10,077 oracle bone inscription images spanning five phases of the Shang Dynasty, featuring 93,652 annotated characters, 21,667 recorded missing-character positions, 21,941 sentence units, and 4,192 non-sentential elements. By integrating visual, structural, and linguistic modalities, OBIMD supports multi-modal learning and diverse tasks such as facsimile enhancement, character retrieval, and syntactic reconstruction. It constitutes a foundational resource for oracle bone inscription recognition and interpretation, enabling scalable and systematic analysis of ancient Chinese writing.

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
