ObjectiveIn order to study the active design method of normal circular arc tooth profile pure rolling cylindrical gears based on meshing line equations, to gain a deeper understanding of the meshing characteristics of this new type of gears, including contact marks and non load transmission errors, and to better grasp the effects of center distance
We report a case of progressive vitiligo with rosette sign under dermatoscope.A 58-year-old man Gimbal complained of white patches on the dorsal hands, scrotum and groin for 3 months.Dermatological examination revealed round or irregularly shaped hypopigmented spots or porcelain white patches with sharp or undefined boundaries on the dorsal hands,
In order to solve the problem that the high computational burden of the multiple signal classification algorithm of non-circular signal (NC-MUSIC) in direction-of-arrival (DOA) estimation,a novel computationally efficient DOA estimation algorithm based on subspace rotation technique was proposed.Firstly,the partitioning of noise subspace matrix and
The assessment of psychosocial impacts related to coastal hazards (erosion, submersion) has so far been mainly qualitative.As cost-benefit analysis is gaining popularity among communities to assess adaptation options in the face of increasing coastal hazards, there is a need to develop quantitative indicators to improve the inclusion of human impac
ABSTRACTCells activate protective mechanisms to overcome stressful conditions that threaten cellular homeostasis, including imbalances in calcium, redox, and nutrient levels.Endoplasmic reticulum (ER) stress activates an intracellular signaling pathway, known as the unfolded protein response (UPR), to mitigate Lid Magnet Housing such circumstances
