Measuring nanomechanical motion with an imprecision far below the standard quantum limit

open access: yes, 2010
We demonstrate a transducer of nanomechanical motion based on cavity enhanced optical near-fields capable of achieving a shot-noise limited imprecision more than 10 dB below the standard quantum limit (SQL).

Modulating the Charge Transfer Channels via Constructing Charge‐Assisted Hydrogen‐Bonded Organic Frameworks for Enhanced Photosynthesis of Hydrogen Peroxide

open access: yesAdvanced Science, EarlyView.
This work reports a strategy of engineering charge‐assisted hydrogen bonds to tailor charge transfer channels in HOFs, significantly improving their performance in photocatalytic H2O2 production. ABSTRACT The production of H2O2 via artificial photosynthesis is often limited by inefficient charge‐carrier separation, causing significant charge ...

New Hybrid Model Combining NoSQL and SQL Database to Ameliorate the Performance of Big Data System

open access: yesIraqi Journal for Computers and Informatics
Due to their flexibility, NoSQL databases have gained popularity as a preferred data storage destination of modern web applications and can accommodate easy growth. But they are not without risk: Technical Articles can be susceptible to injection attacks

Bridging the Semantic Gap with SQL Query Logs in Natural Language Interfaces to Databases

open access: yes, 2019
A critical challenge in constructing a natural language interface to database (NLIDB) is bridging the semantic gap between a natural language query (NLQ) and the underlying data. Two specific ways this challenge exhibits itself is through keyword mapping

The Interoperability Challenge in DFT Workflows Across Implementations

open access: yesAdvanced Intelligent Discovery, EarlyView.
Interoperability and cross‐validation remain major challenges in the computational materials science. In this work, we introduce a common input/output standard that enables internal translation across multiple workflow managers—AiiDA, PerQueue, Pipeline Pilot, and SimStack—while producing results in a unified schema.

Educational pathways and outcomes for care‐experienced children: A 16‐year longitudinal study

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Children who are removed from their birth families during childhood—termed care‐experienced—can be at risk for lower educational attainment and poorer school experiences, often linked to deprivation and behavioural factors. However, research often uses aggregated measures that obscure the complexities of care (e.g.

Force stimulation promotes nerve regeneration by restoring cellular energy

open access: yesBMEMat, EarlyView.
Mechanical stimulation can help nerves regenerate in various ways. We developed two devices (a piezo‐motor‐driven stretching device and a SAW‐based actuator) to apply mechanical stimulation to sciatic nerve and DRG neurons. Our study shows that appropriate mechanical force stimulation can promote regeneration by restoring the energy supply to the ...

A Critical Analysis of Microsoft's Rhetoric and Reality of Sustainability Engagement

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study critically examines Microsoft's environmental, social and governance (ESG) rhetoric and operational reality, to offer insights that extend beyond conventional greenwashing or bluewashing. Drawing on over 20 years of Microsoft's sustainability reports (2003–2024), third‐party ESG evaluations and media investigations, it employs ...
