Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Synthesis of robust memory modes for linear quantum systems with unknown inputs
未知输入 线性量子系统 鲁棒记忆模式
2023/11/7
In this work, synthesis of robust memory modes for linear quantum passive systems in the presence of unknown inputs has been studied, aimed at facilitating secure storage and communication of quantum ...
Abelian networks are systems of communicating automata satisfying a local commutativity condition. We show that a finite irreducible abelian network halts on all inputs if and only if all eigenvalues ...
There are thousands of deepwater sites in the Gulf of Mexico
where persistent natural hydrocarbon seepage contributes
to the formation of authigenic carbonate hardgrounds on a
seafloor dominated...
Atmospheric inputs of phosphorus and nitrogen to the southwest Mediterranean region: Biogeochemical responses of high mountain lakes
Biogeochemical responses Atmospheric inputs
2014/5/4
We quantified dry and wet deposition of dust, nitrogen, and phosphorus over the southwest Mediterranean region (Sierra Nevada, Spain) and assessed its effects on the nutrient status and the chlorophyl...
Response of phytoplankton in an alpine lake to inputs of dissolved organic matter through nutrient enrichment and trophic forcing
Response of phytoplankton trophic forcing
2014/4/2
Inputs of terrestrially derived dissolved organic matter (DOM) are increasing in alpine lakes due to multiple
drivers such as climate change, tree line advancement, and insect epidemics. A 21 d micro...
Basin-scale inputs of cobalt, iron, and manganese from the Benguela-Angola front to the South Atlantic Ocean
Basin-scale inputs of cobalt, iron manganese Benguela-Angola South Atlantic Ocean
2014/4/4
We present full-depth zonal sections of total dissolved cobalt, iron, manganese, and labile cobalt from the South Atlantic Ocean. A basin-scale plume from the African coast appeared to be a major sour...

Nonlinear Stabilization under Sampled and Delayed Measurements, and with Inputs Subject to Delay and Zero-Order Hold
feedback stabilization time-delay systems sampled-data systems nonlinear control
2011/1/20
Sampling arises simultaneously with input and output delays in networked control systems. When the delay is left uncompensated, the sampling period is generally required to be sufficiently small, the ...
Shared inputs and desynchrony in elliptic bursters: from slow passage to discontinuous circle maps
Dynamical Systems (math.DS) Chaotic Dynamics (nlin.CD)
2010/11/10
What input signals will lead to synchrony vs. desynchrony in a group of biological oscillators? This question connects with both classical dynamical sys- tems analyses of entrainment and phase locking...
Asymptotics of stationary solutions of multivariate stochastic recursions with heavy tailed inputs and related limit theorems

2010/11/12
Let $\Phi_n$ be an i.i.d. sequence of Lipschitz mappings of $\R^d$. We study the Markov chain $\{X_n^x\}_{n=0}^\8$ on $\R^d$ defined by the recursion $X_n^x = \Phi_n(X^x_{n-1})$, $n\ge 0$, $X_0=x\in\...

marine oligotrophic ecosystems atmospheric inputs Large clean mesocosms
2011/11/14
Intense Saharan dust deposition occurs over large oligotrophic areas in the Mediterranean Sea and in the Tropical Atlantic, and its impact on the biogeochemical functioning of such oligotrophic ecosys...

Identifiability Nonlinear delayed-differential models
2010/12/1
In this paper, an original result in terms of a sufficient condition to test identifiability of nonlinear delayed-differential models with constant delays and multi-inputs is given.
Nutrient inputs to the coastal ocean from submarine groundwater discharge in a groundwater-dominated system: Relation to land use (Kona coast, Hawaii, U.S.A.)
Nutrient inputs the coastal ocean submarine groundwater discharge in a groundwater-dominated system Relation to land use
2014/4/17
We evaluated the magnitude and composition (in terms of salinity,223Ra and224 Ra activity, and nutrient concentrations) of submarine groundwater discharge (SGD) fluxes at 11 sites on the Kona coast of...
