We study the dilepton-dijet signal in the dominant Higgs production channel at a linear e+e− collider. We estimate the effects of Universal Extra Dimension (UED) by a simple analysis of the cross-sections. The heavy Kaluza-Klein excitations of the Standard Model fields in UED can significantly alter the decay properties of the Higgs boson to loop-driven final states. We show that by taking a si...

The arriving abundances of a variety of cosmic-ray nuclides consist of comparable amounts of primary material produced by stellar nucleosynthesis and secondary matter resulting from fragmentation of heavier nuclei by collisions during interstellar propagation. We discuss a technique for extracting the primary and secondary contributions that takes advantage of energy spectra of individual nucli...

Residual stresses have considerable effect on both the local and member stability behaviour of steel structures. Previous studies shown that structural depends distribution amplitude residual stresses. The stress is affected by cross-section geometry, grade manufacturing process, e.g. flame cutting welding procedure. A realistic consideration necessary for an efficient safe design This article ...

The prediction of cross sections for nuclei far off stability is crucial in the field of nuclear astrophysics. We calculate direct neutron capture on the even-even isotopes 124−145Sn and 208−238Pb with energy levels, masses, and nuclear density distributions taken from different nuclear-structure models. The utilized structure models are a Hartree-Fock-Bogoliubov model, a relativistic mean fiel...

We summarize results for the processes eγ → W−νe, e Z, eγ within the electroweak Standard Model. We discuss the essential features of the corresponding lowest-order cross-sections and present numerical results for the unpolarized cross-sections including the complete O(α) virtual, soft-photonic, and hard-photonic corrections. While at low energies the weak corrections are dominated by the leadi...

This paper presents an efficient numerical procedure for the rapid design of arbitrary-shaped composite steelconcrete cross-sections that are subjected to biaxial bending and axial force. The design procedure allows cross-sections to be designed by solving directly for the reinforcement required to provide a cross-section with adequate strength. The new numerical procedure developed in this pap...

Wire arc additive manufacturing (WAAM) is a promising metal 3D printing technique in the construction industry for its ability to produce large and complex-shaped elements, with reasonable accuracy, time costs. There currently, however, lack of fundamental test data on structural performance WAAM elements. To address this, an experimental study into cross-sectional behaviour tubular beams has b...

When alveoli are inflated, the stretched alveolar walls draw their capillaries into oval cross sections. This causes the disk-shaped red blood cells to be oriented near alveolar gas, thereby minimizing diffusion distance. We tested these ideas by measuring red blood cell orientation in histological slides from rapidly frozen rat lungs. High lung inflation did cause the capillaries to have oval ...
