Abstract Ultrasound image segmentation plays an important role in computer-aided diagnosis of breast cancer. Existing approaches focused on extracting the tumor tissue to characterize the tumor class. However, other tissues are also helpful for providing the references. In this paper, a multi-target semantic segmentation approach is proposed based on the fully convolutional network for segmenting the breast ultrasound image into different target tissue regions. For handling the...

Abstract We purpose a novel method that combines modified frequency slice wavelet transform (MFSWT) and convolutional neural network (CNN) for classifying normal and abnormal heart sounds. A hidden Markov model is used to find the position of each cardiac cycle in the heart sound signal and determine the exact position of the four periods of S1, S2, systole, and diastole. Then the one-dimensional cardiac cycle signal was converted into a two-dimensional time-frequency picture using...

As we experience the uncomfortable but necessary changes in response to COVID-19, many of us have continued our work by switching to virtual spaces, whether for meetings, classes, social events, or other gatherings. We are presented with an opportunity to make virtual spaces more accessible, which means more disabled people will be able to actively be present. On the flipside of this opportunity, however, is a threat that accessibility will be ignored, if not erased. We must be intentionally inclusive...

On March 9, the American Anthropological Association hosted a successful #AccessibleAnthChat on Twitter, focusing on the issue of fieldwork accessibility. Disabled and nondisabled anthropologists joined the chat to discuss five questions related to the accessibility/inaccessibility of fieldwork as well as the importance of fieldwork to members of our discipline. Disabled anthropologists shared their personal experiences of how fieldwork remained inaccessible to them or how anthropology’s approach...

“Let the shameful wall of exclusion finally come tumbling down.” —President George H. W. Bush, Sr. On July 26, 1990, President George H. W.

(Unsplash/)Virologists and other scientific experts still know relatively little about SARS-CoV-2, the virus that causes COVID-19. But the ever-growing body of evidence about how the virus is transmitted suggests that tiny airborne particles, commonly known as aerosols, play a big role in spreading the microbe...
