The effect of long-term creep and prestressing on moment redistribution of balanced cantilever cast-inplace segmental bridge [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2007
This paper addresses the effect of long-term creep and prestressing on moment redistribution for large prestressed concrete segmental bridge constructed by the balanced cantilever method. The PathumThani bridge across the Chao Praya River is investigated

Solvent effect on the absorption and emission spectra of carbon dots: evaluation of ground and excited state dipole moment

BMC Chemistry, 2021
Background Carbon dots (C-dots) are photoluminescent nanoparticles with less than 10 nm in size. Today, many studies are performed to exploit the photoluminescence (PL) property of carbon dots, and our focus in this study is to estimate the dipole moment

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Structure–Function Decoupling of the Sensorimotor and Default Mode Networks in Black Americans With MS

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background and Objectives Multiple sclerosis (MS) exhibits racially disparate rates of disease progression. Black people with MS (B‐PwMS) experience a more severe disease course than non‐Hispanic White people with MS (NHW‐PwMS). Here we investigated structural and functional connectivity as well as structure–function decoupling in the ...

Influence of increasing differential settlement under columns on a RC frame response considering different support conditions [PDF]

Journal of Structural and Construction Engineering, 2019
Natural hazards and human activities bring about overall or local ground subsidence. Predicting the effects of large differential settlement on response of structural frames, especially in congested urban areas, is a main issue in design process as ...

Clinical Validation of Plasma p‐217tau in Neurological Diseases

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Plasma p‐217tau is a minimally invasive but specific biomarker for diagnosing Alzheimer's disease (AD). However, its disease specificity remains to be clinically evaluated. We validated the reliability of the p‐217tau biomarker in 12 other neurological diseases.

Machine learning-based prediction of moment redistribution in statically indeterminate reinforced concrete flexural members

Discover Civil Engineering
The transfer of moments between critical and non-critical regions is a key behavior in statically indeterminate reinforced concrete (RC) structures, enhancing the utilization of less critical sections and improving the overall ductility and safety of the

The Influence of Longitudinal Force on the Internal Force Distribution and Deformation Coordination Mechanism for Segment Lining

Advances in Civil Engineering, 2021
A series of local prototype tests are conducted on the Sutong GIL (Gas-Insulated Line) and Shiziyang Tunnel. These tests investigate the redistribution law of segment deformation and the bending moment during construction.

Effect of Foot Orthoses on Midfoot Pain and the Volume of Bone Marrow Lesions in the Midfoot: A Randomized Mechanism of Action Study

Arthritis Care &Research, EarlyView.
Objective Foot orthoses are thought to improve pain by potentially modifying internal mechanical forces. To test this, we explored whether foot orthoses can modify patterns of bone marrow lesions (BMLs) in people with midfoot pain. Methods Forty‐two people were recruited with midfoot pain, and magnetic resonance imaging–confirmed midfoot BMLs ...

Ductility of continuous RC beams strengthened with partially bonded near-surface mounted CFRP bars

Journal of King Saud University: Engineering Sciences
Carbon fiber–reinforced polymer (CFRP) rods have been implemented for repair and strengthening work in several applications for reinforced concrete (RC) elements. The linear brittle behavior of these composite materials can be an excessive limitation for
