Being able to automatically predict digital picture quality, as perceived by human observers, has become important in many applications where humans are the ultimate consumers of displayed visual information. Standard dynamic range (SDR) images provide 8 bits/color/pixel. High dynamic range (HDR) images which are usually created from multiple exposures of the same scene, can provide 16 or 32 bits/color/pixel, but must be tonemapped to SDR for display on standard monitors. Multi-exposure fusion (MEF) techniques bypass HDR creation, by fusing the exposure stack directly to SDR format while aiming for aesthetically pleasing luminance and color distributions...

INTRODUCTOIN: The prevalence of childhood cardiovascular disease (CVD) risk factors often increases in more rural geographic regions in the USA. However, research on the topic often has conflicting results. Researchers note differences in definitions of rurality and other factors that would lead to differences in inference, including appropriate use of statistical clustering analysis, representative data, and inclusion of individual-level covariates. The present study's objective was to examine CVD risk factors during childhood by geographic distribution in the US Appalachian region as a first step towards understanding the health disparities in this area...

PURPOSE: Tumour hypoxia is a major cause of radiation resistance, often present in various solid tumours. Dynamic [(18) F]-fluoromisonidazole (FMISO) PET imaging is able to reliably assess tumour hypoxia. Comprehensive characterization of tumour microenvironment through FMISO-PET and dynamic contrast enhanced (DCE) MR multimodality imaging might be a valuable alternative to the dynamic FMISO-PET acquisition. The aim of this work was to explore the correlation between the FMISO-PET and DCE-MRI kinetic parameters...

Abiotic stresses, including drought, salinity, heat, and cold, negatively affect maize (Zea mays L.) development and productivity. To elucidate the molecular mechanisms of resistance to abiotic stresses in maize, RNA-seq was used for global transcriptome profiling of B73 seedling leaves exposed to drought, salinity, heat, and cold stress. A total of 5,330 differentially expressed genes (DEGs) were detected in differential comparisons between the control and each stressed sample, with 1,661, 2,019, 2,346, and 1,841 DEGs being identified in comparisons of the control with salinity, drought, heat, and cold stress, respectively...

Interleukin-28B (IL28B) single-nucleotide polymorphisms (SNPs) constitute important host-related factors influencing the response rate to Hepatitis C virus (HCV) standard antiviral therapy. In the last few years, several new technologies for SNP detection have been developed. However, the sensitivity and specificity of various methods are different and needs evaluation. Five different methods (resolution melting curve [RMC], polymerase chain reaction-restriction fragment length polymorphism [PCR-RFLP], PCR-sequencing analysis, amplification refractory mutation system [ARMS], and zip nucleic acid probe-based real-time PCR [ZNA]) were developed for genotyping rs12979860 associated with IL28B...

BACKGROUND: From 1963-1995, a factory in Willits, Mendocino County, CA used toxic hexavalent chromium (Cr(VI)) without adequate measures to protect the population. We use longitudinal hospital data to compare reproductive outcomes for two generations in Willits and two generations in the Rest of County (ROC). This is the first study to quantify the reproductive impact of Cr(VI) in a non-occupational population. METHODS: We searched California hospital discharge data (1983-2014) to find Mendocino County residents born 1950 or later...

HTLV-1 bZIP factor (HBZ) is a key player in proliferation and transformation of HTLV-1-infected cells, thus contributing to ATL development. HBZ deregulates gene expression within the host cell by interacting with several cellular partners. Through its C-terminal ZIP domain, HBZ is able to contact and activate JunD, a transcription factor of the AP-1 family. jund mRNA is intronless but can generate two protein isoforms by alternative translation initiation: JunD full-length and ΔJunD, an N-terminal truncated form unresponsive to the tumor suppressor menin...

HD-ZIP IV proteins belong to the homeodomain-leucine zipper (HD-ZIP) transcription factor family and are involved in trichome development and drought stress in plants. Although some functions of the HD-ZIP IV group are well understood in Arabidopsis, little is known about their function in cotton. In this study, HD-ZIP genes were identified from three Gossypium species (G. arboreum, G. raimondii and G. hirsutum) and clustered into four families (HD-ZIP I, II, III and IV) to separate HD-ZIP IV from the other three families...

Homeodomain-leucine zipper (HD-Zip) gene family plays important roles in various abiotic stresses and hormone signaling in plants. However, no information is currently available regarding this family in cassava (Manihot esculenta), an important drought-tolerant crop in tropical and sub-tropical areas. Here, 57 HD-Zip genes (MeHDZ01-57) were identified in the cassava genome, and they were classified into four subfamilies based on phylogenetic analysis, which was further supported by their gene structure and conserved motif characteristics...

By applying a controlled mechanical load using optical tweezers, we measured the diffusive barrier crossing in a 49 nt long P5ab RNA hairpin. We find that in the free-energy landscape the barrier height (G(‡)) and transition distance (x(‡)) are dependent on the loading rate (r) along the pulling direction, x, as predicted by Bell. The barrier shifted toward the initial state, whereas ΔG(‡) reduced significantly from 50 to 5 kT, as r increased from 0 to 32 pN/s. However, the equilibrium work (ΔG) during strand separation, as estimated by Crook's fluctuation theorem, remained unchanged at different rates...

Inspired by recent experiments on the dynamics of particles and polymers in artificial cytoskeletons and in cells, we introduce a modified Langevin equation for a particle in an environment that is a viscoelastic medium and that is brought out of equilibrium by the action of active fluctuations caused by molecular motors. We show that within such a model, the motion of a free particle crosses over from superdiffusive to subdiffusive as observed for tracer particles in an in vitro cytoskeleton or in a cell. We investigate the dynamics of a particle confined by a harmonic potential as a simple model for the motion of the tethered head of kinesin-1...
