Prototypical Contrast Adaptation for Domain Adaptive Semantic Segmentation
Unsupervised Domain Adaptation (UDA) aims to adapt the model trained on the
labeled source domain to an unlabeled target domain. In this paper, we present
Prototypical Contrast Adaptation (ProCA), a simple and efficient contrastive
learning method for unsupervised domain adaptive semantic segmentation.
Previous domain adaptation methods merely consider the alignment of the
intra-class representational distributions across various domains, while the
inter-class structural relationship is insufficiently explored, resulting in
the aligned representations on the target domain might not be as easily
discriminated as done on the source domain anymore. Instead, ProCA incorporates
inter-class information into class-wise prototypes, and adopts the
class-centered distribution alignment for adaptation. By considering the same
class prototypes as positives and other class prototypes as negatives to
achieve class-centered distribution alignment, ProCA achieves state-of-the-art
performance on classical domain adaptation tasks, {\em i.e., GTA5
Cityscapes \text{and} SYNTHIA Cityscapes}. Code is available at

The electromagnetic decays of as the state and its radial excited states
We study the electromagnetic (EM) decays of as the
state by using the relativistic Bethe-Salpeter method. Our
results are keV,
keV,
keV and
keV. The ratio , agrees with the experimental
data. Similarly, the EM decay widths of , , are
predicted, and we find the dominant decays channels are
, where . The
wave function include different partial waves, which means the relativistic
effects are considered. We also study the contributions of different partial
waves.Comment: 20 pages, 6 figures, 9 table
Learning Styles of Undergraduate and Graduate Physical Therapy Students in Taiwan
AbstractThe research was conducted to identify the learning styles of undergraduate and graduate physical therapy students in Taiwan and to examine the associations between learning style and academic performance. Basic data and Kolb's Learning Style Inventory were obtained from 52 participants from one university. The most commonly occurring style of learner was assimilator (44%), followed by diverger (23%), accommodator (15%), and converger (17%). There was no significant difference in academic performance among the four different styles of learners. Qualitative analyses provided further understanding of the preferred learning and teaching strategies. The different strategies are recommended to meet studentsβ learning preferences
