Soil water deficit as a tool to measure water stress and inform silvicultural management in the Cape Forest Regions, South Africa
Soil Water Availability Climatic Gradient Slash Pine Monterey Pine Edaphic Properties
2024/1/19
An understanding of variations in water availability to plantation forests on a spatial and temporal scale is essential when designing risk averse and site-specific silvicultural management regimes. V...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Projective measure without Projective Baire
投射贝尔 投射测量 勒贝格可测
2023/5/6
In this talk, I will give some of the context and a sketch of the proof of the following result which I proved a while ago: It is consistent (relative to a Mahlo catrdinal) that there is a projective ...
Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Inverse problem for the harmonic measure
谐波测量 反问题 双曲群
2023/4/17
Sample paths of a random walk on a hyperbolic group are known to converge to the Gromov boundary. The distribution of the exit point is called the harmonic measure. I will discuss the following invers...

What will be the impact to the ocean if humans are to mine the deep sea? It’s a question that’s gaining urgency as interest in marine minerals has grown.
Physicists harness quantum “time reversal” to measure vibrating atoms（图）
量子 时间反转 振动原子 原子钟 量子传感器
2023/6/9
The quantum vibrations in atoms hold a miniature world of information. If scientists can accurately measure these atomic oscillations, and how they evolve over time, they can hone the precision of ato...
New technology paves way towards personalized antibiotic therapy New sensor provides quick test to measure antibiotic resistance
microwave sensor antibiotics resistance bacteria
2021/8/10
Researchers have developed a method for monitoring bacterial responses to antibiotics in health-care settings that opens the door to personalized antibiotic therapy for patients. Using microwave sensi...
Water regulation in leaves is vital to a plant’s health, affecting its growth and yield, disease susceptibility and drought resistance.
Researchers to measure 'coronavirus slide' in kids' reading skills（图）
measure coronavirus slide kids reading skills
2020/5/9
Teachers have long been familiar with the "summer slide" -- the loss of reading skills among kindergarteners through second graders in the three months away from the classroom. Now researchers at Yale...
When a chemical spills, it's important to know how quickly the spill will spread. When irrigating a crop, a farmer needs to know how fast water moves through soil for absorption by roots. In both case...
