Neural Radiance Fields (NeRF) achieve photo-realistic view synthesis with densely captured input images. However, the geometry of NeRF is extremely under-constrained given sparse views, resulting in significant degradation of novel view synthesis quality. Inspired by self-supervised depth estimation methods, we propose StructNeRF, a solution to novel view synthesis for indoor scenes with sparse inputs.

Existing generation methods are mainly built upon rasterized glyph images to utilize the successful convolutional architecture, but ignore the vector nature of glyph shapes. We present an implicit representation, modeling each glyph as shape primitives enclosed by several quadratic curves.

Special attention was given to understand the influencing of water quality parameters and toxicity changes during the co-exposure process. The results show that the co-exposure process prompted TCS elimination quickly and effectively, with more than 99% of TCS degraded under the experimental conditions.

The effects of several factors such as UV wavelength,UV intensity,sodium persulfate dosage,pH value,and HA on TCS degradation were investigated. The second-order rate constants of free radicals (·OH, SO) reacting with TCS and their contributions to TCS removal were determined,respectively.

The UV/ClO2 process for triclosan ( TCS) removal was studied. The influences of several factors such as the initial pH, dose of ClO2, initial concentration of TCS and humic acid( HA) on TCS degradation in the UV/ClO2 combined process were discussed. The results showed that the UV/ClO2 process could effectively remove TCS and had a synergistic effect.

Objective: To investigate the role of mitochondrial pathway in the apoptosis of spermatogenic cells induced by inhalation of carbon disulfide in male rats.
Methods: Twenty-four male Sprague-Dawley rats (clean grade) were divided into four groups according to their body weights: three CS(2) exposure groups (CS(2) concentrations: 50, 250, and 1250 mg/m(3)) and a control group. The rats in CS(2) exposure groups were exposed to CS(2) by static inhalation for 10 weeks (2 h/d, 5 d/w), while the rats in control group were exposed to air.

Objective: To investigate the effect of carbon disulfide (CS(2)) on the mitochondrial respiratory chain in testicular spermatogenic cells in male rats and to explore the possible mechanism of reproductive system damage caused by CS(2) in male rats.
Methods: Twenty-four male Sprague-Dawley rats (clean grade) were randomly divided into four groups: three CS(2) exposure groups (CS(2) concentrations: 50, 250, and 1250 mg/m(3)) and a control group. The rats in CS(2) exposure groups were exposed to CS(2) by static inhalation for 10 weeks (2 h/d, 5 d/w), while the rats in control group were exposed to air.

Objective: To investigate the effect of maternal decabromodiphenyl ether (BDE-209) exposure on the sexual development in male offspring rats.
Methods: Twenty-four pregnant Sprague-Dawley rats were randomly divided into three BDE-209 exposure groups and one control group. The three BDE-209 exposure groups were given BDE-209 (100, 300, and 900 mg/kg) by gavage on gestational days 12∼18, and the control group was given corn oil.
A cross-sectional study was initiated to clarify whether the current level of exposure to carbon disulphide (CS(2)) is low enough to prevent occurrence of subclinical health impairments. This paper describes the effects of exposure to CS(2) on male sexual function and semen quality in a baseline observation. The effects of CS(2) on male sexual function were evaluated, including number of sexual encounters and length of sexual encounters related to solvents in 80 male workers exposed to CS(2) and 49 reference workers from the filature and cotton pulp departments of a fabric factory in China.

The eutrophic and oligotrophic basins of a Chinese shallow lake (Lake Donghu), in terms of ammonium (NH(+)(4)) concentrations, were sampled. The AOB number was significantly lower in the oligotrophic basin, but significantly higher in the eutrophic basin.

Many epidemiological investigations and animal experiments have indicated that learning and memory ability can be affected to different degrees after long-term exposure to CS(2), but the mechanisms are still unclear. The aim of this study was to explore the possible mechanisms of CS(2)-related impairment of the learning and memory ability of rats, by investigating the effects of CS(2) on nitric oxide synthase (NOS) activity and NOS mRNA expression in rat hippocampus.

Methods: Sertoli cells were exposed to different concentrations of CS(2) (0, 0.36, 0.
Objective: To study the antagonistic joint action of vitamin E (VE) lipid peroxidation of testis in the male rats with carbon disulfide (CS2).
Methods: 36 wistar male rats were randomly dicided into six groups. It took 10-week for the rats to breath CS2 in different concentrations (0, 50, 250 and 1250 mg/m3), respectively, CS2 (1250 mg/m3) with VE (250 mg/kg diet) and VE (250 mg/kg diet) group.
