On multiple context-free grammars

open access: yesTheoretical Computer Science, 1991
AbstractMultiple context-free grammars (mcfg's) is a subclass of generalized context-free grammars introduced by Pollard (1984) in order to describe the syntax of natural languages. The class of languages generated by mcfg's (called multiple context-free languages or, shortly, mcfl's) properly includes the class of context-free languages and is ...

Gastrointestinal Perforation as a Safety Concern Among Patients With Rheumatoid Arthritis Receiving JAK Inhibitor Therapy: A Systematic Review and Network Meta‐Analysis

open access: yesArthritis Care &Research, EarlyView.
Objective Gastrointestinal perforation (GIP) is a rare and life‐threatening safety concern associated with JAK inhibitors (JAKi). We aimed to review the evidence regarding the risk of GIP associated with the use of JAKi in patients with rheumatoid arthritis (RA) using a systematic review and network meta‐analysis approach.

Protein Secondary Structure Patterns in Short‐Range Cross‐Link Atlas

open access: yesAngewandte Chemie, EarlyView.
Short‐range cross‐linking mass spectrometry (XL‐MS) reveals secondary structure‐dependent patterns in proteome‐wide datasets. By integrating XL‐MS data with AlphaFold‐predicted structures, we introduce X‐SPAN, a novel validation metric that assesses data quality and enables pLDDT score benchmarking.

Knotify: An Efficient Parallel Platform for RNA Pseudoknot Prediction Using Syntactic Pattern Recognition

open access: yesMethods and Protocols, 2022
Obtaining valuable clues for noncoding RNA (ribonucleic acid) subsequences remains a significant challenge, acknowledging that most of the human genome transcribes into noncoding RNA parts related to unknown biological operations.

The Versatility of Layered Two‐Dimensional Heterostructures for Energy Storage: Bridging Scientific Insights and Practical Applications

open access: yesAdvanced Materials, EarlyView.
This review highlights the potential of 2D‐2D heterostructures (HRs) in advancing monovalent ion‐based energy storage. It examines their role in tailoring charge interactions mechanisms, optimizing interfacial properties, and overcoming the limitations of individual layered materials.

Designing Tunable DNA Condensates to Control Membrane Budding Transformation in Synthetic Cells

open access: yesAdvanced Science, EarlyView.
In giant unilamellar vesicles (GUVs), membrane wetting of encapsulated liquid‐liquid phase‐separated DNA condensates can be precisely triggered post‐fabrication using photoactivatable DNA‐lipid linkers. On free‐standing membranes, interactions between DNA condensates and the membrane lead to outward budding, resembling exocytosis.

A Human Engineered Heart Tissue‐Derived Lipotoxic Diabetic Cardiomyopathy Model Revealed Early Benefits of Empagliflozin

open access: yesAdvanced Science, EarlyView.
This study develops a human engineered heart tissue‐derived model of diabetic cardiomyopathy that accurately replicates the dynamic changes in the structural, contractile, and electrophysiological properties of the myocardium. Furthermore, this model is used to confirm the direct protective effects of empagliflozin on the heart through an SGLT2 off ...

Towards a Context-Free Machine Universal Grammar (CF-MUG) in Natural Language Processing

open access: yesIEEE Access, 2020
In natural language processing, semantic document exchange ensures unambiguity and shares the same meaning for documents sender and receiver cross different natural languages (e.g., English to Chinese), this difference makes the translation between ...

The Locus Coeruleus‐Periaqueductal Gray GABAergic Projection Regulates Comorbid Pain and Depression

open access: yesAdvanced Science, EarlyView.
LC‐GABA neurons exhibit elevated activity to noxious and aversive stimuli in chronic pain, and their activation alleviates pain‐ and depression‐like behaviors. While LC‐GABA neurons target LC‐NA neurons and GABA and Glu neurons in the vlPAG, they modulate the pain responses of LC‐NA neurons but regulate pain‐ and depression‐like behaviors through their

Quantifying the Impact of Cathode Composite Mixing Quality on Active Mass Utilization and Reproducibility of Solid‐State Battery Cells

open access: yesAdvanced Energy Materials, EarlyView.
The origin of variations in solid‐state battery cell performance is explored and traced back mainly to the cathode composite mixing – leading to different fractions of electrochemically active mass. Machine‐mixed composites and the quantification of the electrochemically active mass enhance reproducibility and comparability.
