Temporal shape super-resolution by intra-frame motion encoding using high-fps structured light

One of the solutions of depth imaging of moving scene is to project a static pattern on the object and use just a single image for reconstruction. However, if the motion of the object is too fast with respect to the exposure time of the image sensor, patterns on the captured image are blurred and reconstruction fails. In this paper, we impose multiple projection patterns into each single captured image to realize temporal super resolution of the depth image sequences. With our method, multiple patterns are projected onto the object with higher fps than possible with a camera. In this case, the observed pattern varies depending on the depth and motion of the object, so we can extract temporal information of the scene from each single image. The decoding process is realized using a learning-based approach where no geometric calibration is needed. Experiments confirm the effectiveness of our method where sequential shapes are reconstructed from a single image. Both quantitative evaluations and comparisons with recent techniques were also conducted.Comment: 9 pages, Published at the International Conference on Computer Vision (ICCV 2017

Formate-Free Metal-Organic Decomposition Inks of Copper Particles and Self-Reductive Copper Complex for the Fabrication of Conductive Copper Films

Metal-organic decomposition (MOD) inks have been developed for printed electronics applications. Cu-based MOD inks prevent the oxidation of the metal during storage, as the Cu is already present in an oxidized form (i.e. a salt). However, usually hazardous formates such as Cu (II) formate have to be used as the copper salt in order to ensure thermal decomposition and self-reduction of the metal salt at moderate temperatures (less than 150°C). In this study, a formate-free hybrid ink containing copper particles and a Cu/1-amino-2-propanol (AmIP)/acetate complex was developed for the fabrication of conductive copper films on flexible polymer substrates at low sintering temperatures. A hybrid ink with a weight ratio of 3:1copper particles to MOD ink produced a conductive copper film with close-packed copper particles and a low resistance of 7.3—10-5Ω cm after sintering at a temperature of 180°C for 60 min under a N2 gas flow. Good oxidation resistance of the copper films was observed after exposure to air at 23 °C for two months

The effect on mouse immune systems of cow's colostrum produced 6 to 7 days after parturition

Five-week-old male mice were divided into 2 groups in which they were orally given sterile saline solution (control solution) or cow's colostrum powder prepared from milk produced 6 to 7 days after parturition in sterile saline solution (colostrum solution). The mice were given the solution once a day for 5 weeks. The level of intestinal total IgG was significantly lower in the mice given the colostrum solution than in the mice given the control solution, and the intestinal IgA and serum IgG levels tended to be lower in the mice given the colostrum solution. The numbers of spleen CD11b(+), CD19(+), and IFN-gamma(+)CD4(+) cells were also significantly lower in mice given the colostrum solution. DNA microarray analysis of mRNAs extracted from Peyer's patch cells showed that the gene expression of proteins relating to T cell activation of acquired immune responses or Fc epsilon-mediated mast cell activation was obviously lower in the mice given the colostrum solution than in the mice given the control solution, whereas that of proteins relating to T regulatory cells or intestinal innate immune system was noticeably higher in mice given the colostrum solution. These results suggest that the oral ingestion of cow's colostrum suppresses the acquired immune system and type I allergic reactions, and enhances the innate immune system.ArticleMILCHWISSENSCHAFT-MILK SCIENCE INTERNATIONAL. 65(1):11-15 (2010)journal articl

Na-ion dynamics in Quasi-1D compound NaV2O4

We have used the pulsed muon source at ISIS to study high-temperature Na-ion dynamics in the quasi-one-dimensional (Q1D) metallic antiferromagnet NaV2O4. By performing systematic zero-field and longitudinal-field measurements as a function of temperature we clearly distinguish that the hopping rate increases exponentially above Tdiff=250 K. The data is well fitted to an Arrhenius type equation typical for a diffusion process, showing that the Na-ions starts to be mobile above Tdiff . Such results makes this compound very interesting for the tuning of Q1D magnetism using atomic-scale ion-texturing through the periodic potential from ordered Na-vacancies. Further, it also opens the door to possible use of NaV2O4 and related compounds in energy related applications.Comment: Accepted for publication in Journal of Physics: Conference Series (2014

Lumostatic operation controlled by the optimum light intensity per dry weight for the effective production of Chlorella zofingiensis in the high cell density continuous culture

To maximize the production rate of Chlorella zofingiensis, a lumostatic continuous culture was operated under light intensities of 250–1510 μE m− 2 s− 1. The cell density and volumetric biomass production rate were increased without photo inhibition and reached 13.5 g-dry weight (dw) L− 1 on day 21.5 and 2.41 g-dw L− 1 day− 1 on day 10.5, respectively. These maximum values were higher than any previous photoautotrophic culture study with C. zofingiensis. The specific growth rate was maintained at a high level > 0.5 day− 1 until the light intensity per dry weight decreased below 28 μE g-dw− 1 s− 1, which coincided with the value estimated in our previous study, verifying the reliability of this estimated value. There was a strong relationship between the photosynthetic efficiency and light intensity per dry weight for C. zofingiensis. This relationship may be useful for evaluating species-specific productivity to select productive species

Cellulose-metallothionein biosorbent for removal of Pb(II) and Zn(II) from polluted water

Intake of toxic trace elements in drinking water can lead to adverse health effects. To remove toxic trace elements from water, we developed a novel biosorbent composed of cellulose and a fusion protein. The fusion protein was constructed from metallothionein (MT) and a carbohydrate-binding module (CBM), where CBM can bind to cellulose while MT can capture heavy metal ions in solution. In a batch experiment, the biosorbent had maximum biosorption capacities for Pb(II) and Zn(II) ions of 39.02 mg/g and 29.28 mg/g, respectively. Furthermore, the biosorbent could be used in a semi-continuous system and showed good regeneration and recyclability. Both cellulose and the MT-CBM are environmentally friendly and renewable materials, and this biosorbent has great potential for efficient removal of toxic trace elements from polluted water

Hepatocyte Nuclear Factor 4␣ Regulates Expression of the Mouse Female-Specific Cyp3a41 Gene in the Liver

ABSTRACT: CYP3A41 is a female-specific cytochrome P450 in mouse liver. A putative hepatocyte nuclear factor 4␣ (HNF4␣)-binding site was found at ؊99/؊87 in the promoter of Cyp3a41 by reporter assays performed in the hepatocytes of female mice. Cotransfection of an HNF4␣ expression plasmid significantly increased transcription of the reporter gene. Although electrophoretic mobility shift assays with liver nuclear extracts did not show a sex-related difference, chromatin immunoprecipitation (ChIP) assays showed that larger amounts of HNF4␣ bound to Cyp3a41 in female than in male mice. A relation between the amount of HNF4␣ on the Cyp3a41 gene and mRNA expression was observed in hepatic tissue sets, which differ in mRNA expression depending on the sex, age, or endocrine status of mice. The degree of histone-3-lysine-4 dimethylation and histone-3-lysine-27 trimethylation around the HNF4␣-binding site was higher in females and males, respectively. Moreover, the ChIP assay indicated greater acetylation of histone-4-lysine-8 of the Cyp3a41 chromatin in females than in males. HNF4␣ plays an important role in the transcriptional activation of the Cyp3a41 gene, and a sex difference in chromatin structure may contribute to the female-specific expression of Cyp3a41 in the livers of mice

Transpupillary thermotherapy for atypical central serous chorioretinopathy

Ryosuke Kawamura1,2, Hidenao Ideta1, Hideyuki Hori1, Kenya Yuki2, Tsuyoshi Uno1, Tatsurou Tanabe1, Kazuo Tsubota2, Tsutomu Kawasaki11Ideta Eye Hospital, Kumamoto, Japan; 2Keio University, School of Medicine, Department of Ophthalmology, Tokyo, JapanBackground: Central serous chorioretinopathy (CSC) has been traditionally treated with laser photocoagulation. We thought that transpupillary thermotherapy (TTT) utilizing a lower temperature than that of conventional laser photocoagulation might minimize permanent retinal and choroidal damage. Studies suggest that undesirable effects on vision due to TTT are minimal even if it is applied to foveal and/or parafoveal lesions when TTT requires a larger irradiation spot. The aim of this study was to evaluate the efficacy of TTT in the management of atypical CSC.Methods: We defined atypical CSC as bullous retinal detachment with diffuse or several leakages, severe leakage with fibrin formation under serous retinal detachment, or leakage within a pigment epithelium detachment. Eight consecutive patients with atypical CSC underwent visual acuity testing, ophthalmic examination, color photography, fluorescein angiography, and optical coherence tomography to evaluate the results of transpupillary thermotherapy. Retreatment of atypical CSC was based on ophthalmic examination, optical coherence tomography, and fluorescein angiography. TTT was performed on the leaking spots shown in fluorescein angiography, with a power of 50–250 mW, spot size of 500–1200 µm, and exposure time of 13–60 seconds to minimize retinal damage.Results: In five of eight affected eyes, serous detachments completely resolved within 1 month after the initial TTT. One eye had persistent subretinal fluid and required a second TTT treatment. Two eyes showed no resolution of CSC and were treated by conventional photocoagulation. Initial best-corrected visual acuity (BCVA) ranged from 20/600 to 20/20 (mean, 20/40; median, 20/30). Final BCVA ranged from 20/200 to 20/20 (mean, 20/25; median, 20/20). BCVA improved in all cases. Only two eyes with persistent subretinal fibrin and existing retinal pigment epithelial alternations in macular area showed limited improvement of BCVA despite the absence of subretinal exudation. The presence of retinal attachment was confirmed by optical coherence tomography in six eyes (75%).Conclusions: TTT seems to be effective for the treatment of atypical CSC in the short term. Additional studies are necessary to evaluate the long-term effectiveness and safety.Keywords: transpupillary thermotherapy, central serous chorioretinopathy, optical coherence tomography, fluorescein angiography, serous detachmen
