Discovering the drag force in complex fluids

We feel the drag force from air while walking, jogging or riding a vehicle, and we feel the drag force from sand while walking on the beach. Combining experiments, numerical simulations and theory, physicist Kai Huang addresses the question “How can we predict the trajectory of an object thrown into granular materials, such as sands, powders and grains?” in Nature’s Scientific Reports. The work sheds light on a fundamental understanding of drag force in complex fluids.

Women’s singleness and feminism in 1920s China

In the 1920s, some Chinese intellectuals considered women’s singleness, or the choice to be unmarried, a central part of discussions of marriage, family and gender. Drawing on the works of Shen Zijiu (1898-1989), historian Qian Zhu agues in the International Journal of Gender and Women’s Studies that debate of women’s singleness marked China’s enlightenment movement by rethinking the concept of modernity, in which gender equality and women’s emancipation became the measuring stick of the degrees of civilization.

Energy stable scheme for two-phase flow problems

Mathematician Shixin Xu and fellow researchers have developed a q-NSCH system based on the energy variational method for two-phase flow problems with contact lines and variable density. In a paper published in the Journal of Computational Physics, they propose a mass conserving C0 finite element scheme to solve the PDE system. Various numerical results confirm that the proposed scheme for both P1 element and P2 element are energy stable.

Lack of knowledge points to underreporting of equine zoonotic infection

Worldwide, horses play a critical role in recreation, food production and transportation, and as a result, there remains potential risk for equine zoonotic pathogen transmission to humans. After conducting a systematic review of equine zoonoses, epidemiologist Gregory Gray and colleagues warn that there is a high potential for underreporting zoonotic infections due to lack of knowledge among health professionals.

Stress testing with influencing factors to accelerate data race software failures

Software failures caused by data race bugs remain major concerns in parallel and distributed systems. To address the issue, iAPSE’s Kishor Trivedi and fellow researchers propose in IEEE Transactions on Reliability stress testing with influencing factors, in which the system runs under certain workloads for a long time with controlled stress conditions, and explore mathematical relationship models between data races’ statistical characteristics of time to failure (TTF) or mean TTF and the influencing factors.

Women still missing from cardiovascular trials

Cardiovascular disease is the leading cause of death among women worldwide. So why don’t more women participate in trials? Lijing Yan, an expert in non-communicable diseases, and global health master’s student Xurui Jin, explore the key factors behind the under-representation of women in cardiovascular trials in Circulation, an American Health Association journal.

First ancient DNA from West Africa illuminates deep human past

An international research team including archaeologist Scott MacEachern has produced the first whole-genome ancient human DNA sequences from West and Central Africa. Scientists recovered the data from two pairs of children buried at an iconic archaeological site in Cameroon from between 3,000 and 8,000 years ago. The findings, published by Nature, provide fresh clues in the search to identify the populations that first spoke Bantu languages, the most widespread and diverse group of languages in Africa today.

The continuity of BCI-mediated action and conventional action

In response to an article on technologies controlled via brain-computer interfaces (BCIs), Ege Duman, undergraduate Class of 22, and Daniel Lim, co-director of the Planetary Ethics and Artificial Intelligence Lab, share philosophical and scientific reasons against a qualitative distinction between conventional action and BCI-mediated action that results in a distinction in moral responsibility. Their paper was published in the American Journal of Bioethics: Neuroscience.

How VLSI CAD led the way in machine learning technologies

VLSI computer-aided design (VLSI CAD) has been at the forefront of incorporating cutting-edge algorithms in the software tools and methodologies that engineers use to weave the digital fabric of our world. “Machine Learning in VLSI Computer-Aided Design,” a book co-authored by iAPSE director Xin Li, shows VLSI CAD has also led the way in making good use of machine-learning technologies to automate the design, verification and implementation of the most advanced chips.

The role urgency plays in Nanjing property presales

Writing in the Journal of Cultural Economy about residential property presales at the urban fringe of Nanjing, China, cultural anthropologist Menqi Wang argues for an analytical focus on urgency as a temporal quality that creates the local housing market and facilitates urban accumulation. She examines how urgency, grounded in a linear imagination of urban development, motivates home presales for developers, estate agents and homebuyers.
