Autotrophic degradation of sulfamethoxazole using sulfate-reducing biocathode in microbial photo-electrolysis system.

Sulfamethoxazole is a representative of sulfonamide antibiotic pollutants. This study aims to investigate the degradation pathways of sulfamethoxazole and the response of microbial communities using the autotrophic biocathode in microbial photo-electrolysis systems (MPESs). Sulfamethoxazole with an initial concentration of 2 mg L was degraded into small molecule propanol within 6 h with the biocathode.

Compact on-chip crystalline resonator integration with etching of tapered fiber waveguide.

Whispering-gallery-mode crystalline resonators currently maintain the best quality factor () record; however, compact on-chip packaging is still a challenge, although various coupling architectures have been developed. Here, a chemical etching method is proposed to fabricate a miniaturized tapered fiber waveguide on silicon substrate. The Marangoni effect is implemented to reduce the surface roughness of the cone region.

Sandwich structure magnetometer with a high sensitivity and signal-to-noise ratio based on an ultrahigh-Q CaF resonator.

Whispering gallery mode (WGM) resonators with an ultrahigh quality () factor provide an extremely high resolution for high-precision sensing. However, it is difficult to use them directly in magnetic sensors because of the transparency to the magnetic field. In this paper, a sandwich structure consisting of a neodymium iron boron magnet and calcium fluoride resonator with a factor of 10 is proposed.

Enhanced sulfur recovery and sulfate reduction using single-chamber bioelectrochemical system.

The aim of this study was to investigate the feasibility of sulfate removal and elemental sulfur (S) recovery in the single-chamber bioelectrochemical system (S-BES). The performance of S-BES was compared with that of dual-chamber bioelectrochemical system (D-BES). The S-BES was constructed with graphite felt as the anode and graphite brush as the cathode.

Sulfate reduction and elemental sulfur recovery using photoelectric microbial electrolysis cell.

Elemental sulfur recover from sulfate-rich environment has great significance for the sustainable development of environment and energy. This study aimed to realize simultaneous sulfate reduction and elemental sulfur recovery using a novel photoelectricity microbial electrolysis cell (PMEC) under low applied voltages. At an applied voltage of 1.

On differential photometric reconstruction for unknown, isotropic BRDFs.

This paper presents a comprehensive theory of photometric surface reconstruction from image derivatives in the presence of a general, unknown isotropic BRDF. We derive precise topological classes up to which the surface may be determined and specify exact priors for a full geometric reconstruction. These results are the culmination of a series of fundamental observations.

On the Duality of Forward and Inverse Light Transport.

Inverse light transport seeks to undo global illumination effects, such as interreflections, that pervade images of most scenes. This paper presents the theoretical and computational foundations for inverse light transport as a dual of forward rendering. Mathematically, this duality is established through the existence of underlying Neumann series expansions.

Dynein-dynactin complex is essential for dendritic restriction of TM1-containing Drosophila Dscam.

Background: Many membrane proteins, including Drosophila Dscam, are enriched in dendrites or axons within neurons. However, little is known about how the differential distribution is established and maintained.

Methodology/principal Findings: Here we investigated the mechanisms underlying the dendritic targeting of Dscam[TM1].

Baboon/dSmad2 TGF-beta signaling is required during late larval stage for development of adult-specific neurons.

The intermingling of larval functional neurons with adult-specific neurons during metamorphosis contributes to the development of the adult Drosophila brain. To better understand this process, we characterized the development of a dorsal cluster (DC) of Atonal-positive neurons that are born at early larval stages but do not undergo extensive morphogenesis until pupal formation. We found that Baboon(Babo)/dSmad2-mediated TGF-beta signaling, known to be essential for remodeling of larval functional neurons, is also indispensable for proper morphogenesis of these adult-specific neurons.
