Distributed Optimisation With Communication Delays

open access: yes, 2020
This paper discusses distributed optimization over a directed graph. We begin with some well known algorithms which achieve consensus among agents including FROST [1], which possesses the quickest convergence to the optimum. It is a well known fact FROST has a linear convergence.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Global stability for a respiratory disease model with distributed or discrete delay on complex network

open access: yesElectronic Research Archive
Distributed delay is a core concept in time-delay systems and it has been incorporated into the networked respiratory disease model that elucidates the occurrence of respiratory diseases induced by air pollution.

On stability of cooperative and hereditary systems with a distributed delay

open access: yes, 2015
We consider a system $\displaystyle \frac{dx}{dt}=r_1(t) G_1(x) \left[ \int_{h_1(t)}^t f_1(y(s))~d_s R_1 (t,s) - x(t) \right], \frac{dy}{dt}=r_2(t) G_2(y) \left[ \int_{h_2(t)}^t f_2(x(s))~d_s R_2 (t,s) - y(t)\right]$ with increasing functions $f_1$ and ...

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

open access: yesFEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Oscillation of first order delay differential equations with distributed delay

open access: yesJournal of Mathematical Analysis and Applications, 2004
The author considers the first-order delay differential equation with distributed delay \[ x'(t)+\int_0^{b(t)}R(t,s)x(t-s)\,d\mu(s)=0,\tag{1} \] the first-order nonlinear delay differential equation with distributed delay \[ x'(t)+\int_0^bR(t,s)f(x(t-s))\,d\mu(s)=0,\tag{2} \] and the higher-order delay differential equation \[ x^{(m)}(t)=(-1)^m\sum_{i ...

Energy-Efficient Resource Allocation in Wireless Networks with Quality-of-Service Constraints

open access: yes, 2007
A game-theoretic model is proposed to study the cross-layer problem of joint power and rate control with quality of service (QoS) constraints in multiple-access networks.
