Dual Phases of Apoptosis in Pneumococcal Meningitis [PDF]
The Journal of Infectious Diseases, 2004 Significant injury during bacterial meningitis arises from mechanisms of neuronal apoptosis, particularly in the hippocampus. Apoptosis can involve both the caspase-dependent and the caspase-independent pathway, and, although both pathways have been implicated in pneumococcus-induced neuronal cell death, their relative contributions in vivo are unclear.

Microstructural evolution and strengthening mechanisms in CrxMnFeNi high-entropy alloy
Journal of Materials Research and Technology, 2021 In the present work, we reported the microstructure and mechanical properties of CrxMnFeNi high-entropy alloy (HEA). The microstructures of the HEAs were characterized by scanning electron microscopy (SEM) with electron back-scattered diffraction (EBSD ...

Constraints in dual phase shifting interferometry
Optics Express, 2006 The paper presents approaches based on traditional phase shifting, flexible least-squares, and signal processing methods in dual phase shifting interferometry primarily applied to holographic moiré for retrieving multiple phases. The study reveals that these methods cannot be applied straightforward to retrieve phase information and discusses the ...

Phase Noise Influence in a Dual-Frequency Laser Phase-Shift Range Finder
IEEE Photonics Journal, 2018 The influence of phase noise in a dual-frequency laser phase-shift range finder is theoretically and experimentally investigated. The proposed range finder is based on the use of a coherent dual-frequency laser and direct detection of the backscattered ...

Qualitative Aspects in Dual-Phase-Lag Thermoelasticity [PDF]
SIAM Journal on Applied Mathematics, 2006 We consider the system of dual-phase-lag thermoelasticity proposed by Chandrasekharaiah and Tzou. First, we prove that the solutions of the problem are generated by a semigroup of quasi-contractions. Thus, the problem of the third order in time is well-posed. Then the exponential stability is investigated.

FIBRE LASER WELDING OF DUAL PHASE STEELS
Acta Metallurgica Slovaca, 2015 The fibre laser welding of two different dual phase steels HCT980X and HCT600X was evaluated. The sheets with thickness of 1.2 mm were welded using the solid-state fibre laser IPG type YLR 4500 with maximum output 4.5 kW and wave length 1060 nm at ...

Study of Winding Structure to Reduce Harmonic Currents in Dual Three-Phase Motor
World Electric Vehicle Journal, 2023 Dual three-phase motors have the problem of a large generation of harmonic currents while driving due to small inductance for certain harmonics. The purpose of this paper is to theoretically clarify the effect of the winding structure of dual three-phase
