Status quo and development trend of lost foam casting technology [PDF]

open access: yesChina Foundry, 2014
Lost foam casting (LFC) technology has been widely applied to cast iron and cast steel. However, the development of LFC for Al and Mg alloys was relatively slower than that for cast iron and cast steel.

Identifying Cytokine Motif‐Containing, Immunomodulatory Bacterial Proteins in Human Gut Microbiome

open access: yesAdvanced Science, EarlyView.
By building and constructing HMM (Upper left, blue), the authors identify CMCPs in bacteria genomes and CRC related metagenomes and enriched CRC‐related CMCPs (Upper right, blue). They analyze sequence and structural similarity of hits (Lower left, green), test function with engineered EcN delivered to tumors in a mouse tumor model (Lower right, pink ...

Applying colour-coded particle image velocimetry to the wake of a delta wing across a wide range of angles of attack

open access: yesJournal of Fluid Science and Technology
The forces acting on a delta wing are predominantly influenced by local flow structures, specifically leading-edge vortices (LEVs). This study applies colour-coded particle image velocimetry (PIV) to quantify wake dynamics and lift generation for a delta

Robust decentralized LFC design in a deregulated environment [PDF]

open access: yes2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies. Proceedings, 2004
In this paper, a decentralized robust approach is proposed for load-frequency control (LFC) design in a deregulated environment using bilateral market scheme. First, the effect of bilateral contracts as a set of new input signals is taken into account in the control area dynamical model, and then the LFC problem will be formulated as a multi-objective ...

A Neuromorphic Simulation Framework for Indium‐Gallium‐Zinc‐Oxide Charge‐Trap Synaptic Transistors: From Device Modeling to System Simulation

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a comprehensive framework bridging device fabrication, modeling, and system‐level simulation for an indium‐gallium‐zinc‐oxide (IGZO) charge‐trap synaptic transistor‐based neuromorphic system. By developing a precise SPICE model derived from fabricated IGZO synaptic transistors, the study incorporates parasitic RC loads into array ...

Are There Causal Associations Between Obsessive‐Compulsive Disorder and Cardiometabolic Phenotypes? A Genetic Correlation and Bi‐Directional Mendelian Randomization Study

open access: yesAmerican Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT In epidemiological studies, obsessive‐compulsive disorder (OCD) is robustly associated with increased risk of cardiometabolic disorders, including cardiovascular diseases, type 2 diabetes, and obesity. However, the mechanisms behind these associations are unclear. We conducted genetic correlation analyses to explore shared genetic etiology and

Provisional Dynamic Hinged External Fixation Enables Arthroscopy‐Assisted Circular Frame Reconstruction of Complex Tibial Plateau Fractures

open access: yesArthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To describe the surgical technique and early operative outcomes of using a provisional dynamic external fixator to facilitate arthroscopic‐assisted reduction of complex tibial plateau fractures. Methods Between 2014 and 2024, we conducted a retrospective single‐center case series of Schatzker IV‐VI tibial plateau fractures treated with ...

Comparative efficacy of GLP‐1 RA, tirzepatide and SGLT‐2 inhibitors in metabolic liver disease: A network meta‐analysis

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aim Metabolic liver disease, including nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis, is a major cause of chronic liver dysfunction worldwide, creating an urgent need for effective treatments. This systematic literature review (SLR) and network meta‐analysis (NMA) systematically reviews and compares the efficacy and safety ...
