Point spread function for diffuser cameras based on wave propagation and projection model.

Compared to traditional imaging system, diffuser camera is an easy-built imaging system to capture the light field with small form factor. Its imaging target can be reconstructed by deconvolving the sensor images with the point-spread-function (PSF) at the corresponding depth. However, the existing method to obtain the PSFs is generally relied on measuring point-source-responses at several depths which presents high complexity and low reliability.

Exposure to the endocrine disruptor nonylphenol alters structure and function of thyroid gland in rats.

Objective: Nonylphenol (NP) is an estrogenic-like compound which can induce vitellogenin synthesis in males and immature teleostean species. Known as an endocrine disruptor, it has been reported to affect endocrine glands; however, little is known about its effects on thyroid function. The present study aimed to evaluate whether exposure to NP alters the structure and function of the thyroid gland of rats and/or the underlying mechanisms.

Kinematics of lower limbs of healthy Chinese people sitting cross-legged.

Background: Sitting cross-legged as an activity of daily living and its kinematics have significantly different demands on the arthroplasty of hip and knee, which can be referred in the design of joint arthroplasty.

Objectives: The purpose of this study was to obtain the kinematics of the lower limb in Chinese people during cross-legged sitting.

Study Design: This study identified the necessary requirements for joint arthroplasty to carry out sitting cross-legged activity.

N-[3,5-Dichloro-4-(1,1,2,2-tetra-fluoro-eth-oxy)phen-yl]-2,6-difluoro-benzamide.

In the title compound, C(15)H(7)Cl(2)F(6)NO(2), the conformation of the N-H bond in the amide segment is anti to the C=O bond and the dihedral angle between the two benzene rings is 78.6 (3)°. The terminal -CHF(2) group is disordered over two orientations in a 0.
