Temporal Interference Stimulation Enhances Neural Regeneration

Advanced Science, EarlyView.
Temporal interference (TI) stimulation is proposed as a non‐invasive approach to enhance neural regeneration in the deep brain. Theta‐band TI modulation selectively promotes neural progenitor cell differentiation in vitro and augments hippocampal neurogenesis in amouse model of Alzheimer's disease‐like amyloidosis.

Senomorphic Small Extracellular Vesicles Delivered by a Tissue‐Adhesive α‐Lipoic‐Acid Hydrogel Enable Immuno‐Rejuvenation for Bone‐Tendon Interface Regeneration

Advanced Science, EarlyView.
This work identifies M1 macrophage‐mediated inflammation as a key driver of BMSC senescence and bone microstructural deterioration at the enthesis. A tissue‐adhesive hydrogel delivering senomorphic small extracellular vesicles suppresses this inflammatory‐senescent cascade and enhances BMSC resilience by inhibiting the cGAS‐STING‐NF‐κB pathway.

Efficient Screening of Organic Singlet Fission Molecules Using Graph Neural Networks

Advanced Science, EarlyView.
A high‐throughput screening framework based on graph neural networks (GNNs) and multi‐level validation facilitates the identification of singlet fission (SF) candidates. By efficiently predicting excitation energies across 20 million molecules, and integrating TDDFT calculations, synthetic accessibility assessments, and GW+BSE calculations, this ...

Search engine retrieval of changing information

Proceedings of the 16th international conference on World Wide Web, 2007
In this paper we analyze the Web coverage of three search engines, Google, Yahoo and MSN. We conducted a 15 month study collecting 15,770 Web content or information pages linked from 260 Australian federal and local government Web pages. The key feature of this domain is that new information pages are constantly added but the 260 web pages tend to ...

Web searching and information retrieval

Computing in Science & Engineering, 2004
The first Web information services were based on traditional information retrieval (IR) algorithms and techniques. However, IR algorithms were developed for smaller and more coherent collections than the Web is. Thus Web searching requires new techniques - exploiting linkage among Web pages or extensions of the old ones, for example.

Interaction in information searching and retrieval

Journal of Documentation, 2000
The paper aims to explore the concepts of interaction and interactivity presented in different theoretical models in the fields of human‐computer interaction (HCI) and information‐seeking/searching behaviour, and to relate these to information retrieval (IR) research.

Semantic-Enhanced Information Search and Retrieval

Sixth International Conference on Advanced Language Processing and Web Information Technology (ALPIT 2007), 2007
Information Retrieval (IR) techniques have been extensively studied since late 1940s and achieved great success evidenced particularly by popular online search engines. However, various classical information retrieval models also have witnessed criticism for emphasizing computation with occurrence of words while ignoring semantics (i.e.

A searching procedure for information retrieval

Information Storage and Retrieval, 1964
Abstract A search procedure for an information retrieval system is developed whereby the answer to a question is obtained by maximizing an evaluation function of the system's output in terms of the probability of relevance. Necessary and sufficient conditions are given for a set to be an answer to a query.

An associative search strategy for information retrieval

Information Processing & Management, 1980
Abstract This paper extends Goffman's Indirect Method of Information Retrieval by suggesting a more flexible search strategy. The suggested strategy in its simplified version is more effective than the Boolean strategy used in existing information retrieval systems and can be implemented at comparable costs.
