Effect of longitudinal opening on the structural behavior of reinforced high-strength self-compacted concrete deep beams

Case Studies in Construction Materials, 2020
Deep beams are loaded as a simple beam in which the load is taken to the supports by a compressive force. Beam is classified as a deep beam if the beam has a depth larger than quarter of the clear span.

Behavior of Waste Glass Powder in Concrete Deep Beams with Web Openings

Buildings, 2022
Waste Glass Powder (WGP) could be used as a cement replacement additive to manufacture concrete and solving the problem of environmental pollution. The experimental program was made up of ten simply supported reinforced High-Strength Concrete (HSC) deep ...

Radiotherapy Delivery in Deep Inspiration for Pediatric Patients—Final Results of the Phase II Feasibility Study TEDDI

Pediatric Blood &Cancer, EarlyView.
Abstract Introduction The TEDDI trial tested the feasibility and reproducibility of deep‐inspiration breath‐hold (DIBH) in pediatric patients referred for radiotherapy. This report presents final results, including patient‐reported outcomes (PRO) and dosimetric comparison of DIBH and free‐breathing (FB).

Theoretical and Experimental Studies of Two-Span Reinforced Concrete Deep Beams and Comparisons with Strut-and-Tie Method

Advances in Civil Engineering, 2021
Regarding the complicated behavior of continuous deep beams, a research program including three parts was conducted. First part: three continuous concrete deep beams with different shear span-to-depth ratios (a/h) were tested.

Nuclear PDF for neutrino and charged lepton data

, 2010
Neutrino Deep Inelastic Scattering on nuclei is an essential process to constrain the strange quark parton distribution functions in the proton. The critical component on the way to using the neutrino DIS data in a proton PDF analysis is understanding ...

Neural network modelling of RC deep beam shear strength [PDF]

, 2008
YesA 9 x 18 x 1 feed-forward neural network (NN) model trained using a resilient back-propagation algorithm and early stopping technique is constructed to predict the shear strength of deep reinforced concrete beams.

Simulations of deep pencil-beam redshift surveys [PDF]

Monthly Notices of the Royal Astronomical Society, 2001
We create mock pencil-beam redshift surveys from very large cosmological $N$-body simulations of two Cold Dark Matter cosmogonies, an Einstein-de Sitter model ($ $CDM) and a flat model with $ _0 =0.3$ and a cosmological constant ($ $CDM). We use these to assess the significance of the apparent periodicity discovered by Broadhurst et al.

Prognostic Impact of Treatment Modalities, Including Targeted Compartmental Radio‐Immunotherapy, in a Cohort of Neuroblastoma Patients With CNS Metastases at Relapse

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Neuroblastoma (NB) with central nervous system (CNS) metastases is rare at diagnosis, but occurs more often during relapse/progression. Patients with CNS metastases face a dismal prognosis, with no standardized curative treatment available.

Maximum Shear Strength Limit for Reinforced Concrete Deep Beams

International Journal of Concrete Structures and Materials
Although it is widely known that the shear strength of reinforced concrete (RC) deep beams is higher than that of general RC beams to which Bernoulli’s assumption can be applied, the maximum shear strength limit of deep beams is identical to that of ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.
