Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Approximate Envy-freeness in Indivisible Resource Allocation with Budget Constraints
预算约束 不可分割 资源分配 近似无嫉妒
2023/4/14
We study the fair allocation of indivisible resources under knapsack constraints, where a set of items with varied costs and values are to be allocated to a group of agents. Each agent has a budget co...
A new study co-led by a Cornell researcher has identified serpentinite – a green rock that looks a bit like snakeskin and holds fluids in its mineral structures – as a key driver of the oxygen recycli...

While most climate scientists, including the Intergovernmental Panel on Climate Change, implicitly define "pre-industrial" to be in the late 1800's, a true non-industrially influenced baseline is prob...
Mud volcanoes and microseepage: the forgotten geophysical components of atmospheric methane budget
methane lithosphere degassing mudvolcanoes greenhouse gas geodynamics
2015/9/10
Mud volcanoes and microseepage are two important natural sources of atmospheric methane, controlled by neotectonics
and seismicity. Petroleum and gas reservoirs are the deep sources, and faults and f...
Vegetation cover analysis using a low budget hyperspectral proximal sensing system
hyperspectral proximal sensing unable filters vegetation classification
2015/9/7
This report describes the implementation of a hyperspectral proximal sensing low-budget acquisition system and its application to the detection of terrestrian vegetation cover anomalies in sites of hi...

The past two decades have seen the development of large multidisciplinary oceanographic programs that focus on understanding carbon cycling processes in coastal and oceanic environments. Synthesis and...
A Decade of Directly Measured Sediment N2 Fluxes:What Can Narragansett Bay Tell Us About the Global Ocean Nitrogen Budget?
Directly Measured Sediment N2 Fluxes Narragansett Bay Global Ocean Nitrogen Budget
2015/7/17
The tight coupling between nitrogen and carbon cycling has important implications for global climate. These two cycles are under growing anthropogenic pressures (e.g., warming temperatures, changes in...
Integrated Carbon Budget Models for the Everglades Terrestrial-Coastal-Oceanic Gradient: Current Status and Needs for Inter-Site Comparisons
Terrestrial-Coastal-Oceanic Gradient Inter-Site Comparisons
2015/7/16
Recent studies suggest that coastal ecosystems can bury significantly more C than tropical forests, indicating that continued coastal development and exposure to sea level rise and storms will have gl...
Sea level rise is both a powerful impact of and indicator for global warming and climate change. Observing sea level change, as well as its causes, is therefore a top priority for scientists and socie...
Activity time budget patterns of sheep and goats co-grazing on semi-natural species-rich dry grassland
animal behaviour activity pattern small ruminant mixed pasture semi-natural grassland
2015/6/24
Activity time budget patterns and grazing response to sward and environmental conditions were investigated for paddocks of sheep and goats co-grazing for conservation purposes on a semi-natural specie...
Tunable diode laser measurements of hydrothermal/volcanic CO2 and implications for the global CO2 budget
CO2 low temperature volcanic hydrothermal volcanoes laser and other quantitative volcanoes volcanic hydrothermal
2015/1/6
Quantifying the CO2 flux sustained by low-temperature fumarolic fields in hydrothermal/volcanic environments has remained a challenge, to date. Here, we explored the potential of a commercial infrared...
