Density functional perturbation theory for gated two-dimensional heterostructures: Theoretical developments and application to flexural phonons in graphene [PDF]

open access: yes, 2017
In the search for exciting new physics and the design of next-generation devices, gated two-dimensional heterostructures are becoming omnipresent. As the fabrication and characterization techniques in this field improve, first-principles methods must ...

Splenic flexure volvulus

open access: yesBMJ Case Reports, 2010
We present the case of a woman in her 50s presenting with acute abdominal pain and absolute constipation. Subsequent investigations revealed large bowel obstruction which was shown on computed tomography scan to be secondary to a rare volvulus of the splenic flexure of her colon. The patient was taken for an urgent laparotomy with resection of 45 cm of

Failure-mode-hierarchy-based design for reinforced concrete structures [PDF]

open access: yes, 2005
Innovations in concrete construction can be held back by the inability of codes of practice to accommodate new materials. The current design and safety philosophy (DSP) of reinforced concrete relies heavily on the properties of steel reinforcement.

Amplitude dependence of image quality in atomically-resolved bimodal atomic microscopy [PDF]

open access: yes, 2016
In bimodal FM-AFM, two flexural modes are excited simultaneously. The total vertical oscillation deflection range of the tip is the sum of the peak-to-peak amplitudes of both flexural modes (sum amplitude).

Nonlinear flexural analysis of sandwich beam with multi walled carbon nanotube reinforced composite sheet under thermo-mechanical loading

open access: yesCurved and Layered Structures, 2020
Nonlinear flexural analysis of sandwich composite beam with multiwall carbon nanotube (MWCNT) reinforced composite face sheet and bottom sheet under the thermo-mechanically induced loading using finite element method is carried out.

Effect of vertical circular openings on flexural strength of reinforced concrete beam

open access: yesMagazine of Civil Engineering, 2021
Modern building construction techniques sometimes involve the passing of pipes or ducts for water supply, electrification, and telecommunication through reinforced concrete beams to protect them against mechanical damages and add aesthetic value to ...

Flexural behavior of two-span continuous prestressed concrete girders with highly eccentric external tendors [PDF]

open access: yes, 2005
[Abstract]: It is generally known that the flexural strength of beams prestressed with external tendons is comparatively lower than that of members with internal bonded tendons.

Source Illusion Devices for Flexural Lamb Waves Using Elastic Metasurfaces. [PDF]

open access: yesPhysical Review Letters, 2016
Inspired by recent demonstrations of metasurfaces in achieving reduced versions of electromagnetic cloaks, we propose and experimentally demonstrate source illusion devices to manipulate flexural waves using metasurfaces.
