Diffusion-based Image Translation with Label Guidance for Domain Adaptive Semantic Segmentation
Translating images from a source domain to a target domain for learning
target models is one of the most common strategies in domain adaptive semantic
segmentation (DASS). However, existing methods still struggle to preserve
semantically-consistent local details between the original and translated
images. In this work, we present an innovative approach that addresses this
challenge by using source-domain labels as explicit guidance during image
translation. Concretely, we formulate cross-domain image translation as a
denoising diffusion process and utilize a novel Semantic Gradient Guidance
(SGG) method to constrain the translation process, conditioning it on the
pixel-wise source labels. Additionally, a Progressive Translation Learning
(PTL) strategy is devised to enable the SGG method to work reliably across
domains with large gaps. Extensive experiments demonstrate the superiority of
our approach over state-of-the-art methods.Comment: Accepted to ICCV202
decay in the isobar resonance model
Based on the effective Lagrangian approach, the
decay is studied in an isobar resonance model with the assumption that the
-meson is produced from intermediate nucleon resonances. The
contributions from the , ,
and states are considered. In terms of
the coupling constants and
extracted from the data of the partial decay widths of the s to the
channel, the reaction cross section of the process
and the partial decay widths of the and
processes, respectively, the invariant mass
spectrum and the Dalitz plot for are predicted. It
is shown that there are two types of results. In the type I case, a large peak
structure around 2.09GeV implies that a considerable mount of or
component may exist in the narrow-width state,
but for the wide-width state, it has little
component. In the type II case, a small peak around 2.11GeV may only indicate
the existence of a certain mount of or component in the
narrow-width state, but no information for the wide-width
state. Further BESIII data with high statistics would help
us to distinguish the strange structures of these s
Development of compress air transportation (CAT) for alternative energy utilization
Compress Air Transportation (CAT) is a new concept of transportation that utilizes air as the source of energy. Work on alternative power system for vehicle is becoming very important for the future due to combination of high prices on fuel, emission factor and also the source of the current energy will eventually run out. Several advantages for utilizing air as the source of energy compared to other alternative energy sources makes it become the subject for this project. In this project, a simple transportation utilizing air as the source of energy has been developed. The main component of the engine of the CAT is a device called the "Air Impact Wrench" which can be purchased from local stores. The CAT was tested and analyzed for further studies on expanding this new technology
NADPH Oxidase 1 and Its Derived Reactive Oxygen Species Mediated Tissue Injury and Repair
Reactive oxygen species are mostly viewed to cause oxidative damage to various cells and induce organ dysfunction after ischemia-reperfusion injury. However, they are also considered as crucial molecules for cellular signal transduction in biology. NADPH oxidase, whose only function is reactive oxygen species production, has been extensively investigated in many cell types especially phagocytes. The deficiency of NADPH oxidase extends the process of inflammation and delays tissue repair, which causes chronic granulomatous disease in patients. NADPH oxidase 1, one member of the NADPH oxidase family, is not only constitutively expressed in a variety of tissues, but also induced to increase expression in both mRNA and protein levels under many circumstances. NADPH oxidase 1 and its derived reactive oxygen species are suggested to be able to regulate inflammation reaction, cell proliferation and migration, and extracellular matrix synthesis, which contribute to the processes of tissue injury and repair
