Studying the temporal integration of visual signals is crucial to understand how time spent on different visual tasks can affect emmetropization and refractive error development. In this study we assessed the effect of interrupting positive and negative
Question: The focal length of a converging lens is: - positive - negative - zero - infinite Converging Lens There are majorly two types of lens, converging and a diverging lens. he converging lens converges rays of light that are traveling parallel to its principal axis. We can ...
Idiopathic acute transverse myelitis (IATM) is a focal inflammatory disorder of the spinal cord that results in motor, sensory, and autonomic dysfunction. However, the comparative analysis of MRI-negative and MRI-positive in IATM patients were rarely reported. Objectives The purpose of this study wa...
Dielectrophoresis-actuated in-plane optofluidic lens with tunability of focal length from negative to positive 来自NCBI 作者Q Chen,T Li,Y Zhu,W Yu,X Zhang摘要 This paper reports a tunable in-plane optofluidic lens by continuously tuning a silicone oil-air interface from conca... ...
Nevertheless, the reflectivity of common regenerated gratings with a grating length of several millimetres was typically less than 30%19–22. The use of NIR femtosecond lasers has also been explored for inscribing FBGs with enhanced thermal stabil- ity24–33. Type I-IR gratings with positive ...
However, if the triangle decorates a surface of negative Gaussian curvature, the sum of the angles is less than π, if the integral surface has positive integral curvature, the sum of the angles exceeds π. The angle “excess” (i.e. its difference from π) is thus a measure of the ...
e Shorter time-points of exogenously added monomeric Aβ1-42 already leads to increased size of LAMP1-positive vesicles 3 h after treatment in wt mouse neurons at 12 DIV; 3D-rendering with Imaris from confocal z-stack. High magnification image of LAMP1 labelling from a single focal plane ...
Theoretical and empirical studies of the cultural evolution in technology have often focused on positive observational learning, i.e., copying a successful individual. However, negative observational learning, i.e., avoiding negative or bad exemplar beha
The candidate mutations had the following characteristics: very rare (minor allele frequency o0.01) and scoring positive in at least two out of four pathogenicity-prediction programs. Using data from the healthy sister as a negative control, this filtering approach resulted in only one candidate ...
