On the placing of synchronized vector measurements in network 110 - 330 kV for identification of the Kaliningrad region power system regime

open access: yesE3S Web of Conferences, 2018
A solution is presented for the problem of placing phasor measurement unit to identify the mathematical model of the electric power system in the state space. The criterion for complete observability of the Kalman dynamic system is taken as a basis. As a

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Placement of Synchronized Measurements for Power System Observability [PDF]

open access: yes, 2009
This paper presents a method for the use of synchronized\ud measurements for complete observability of a power system.\ud The placement of phasor measurement units (PMUs), utilizing\ud time-synchronized measurements of voltage and current phasors, is ...

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‐

The role of observability in futures markets [PDF]

open access: yes, 2001
Allaz and Vila (1993) show that oligopolistic industries may become more competitive if a futures market is added previous to the spot market. Later, Hughes and Kao (1997) show that this result occurs only if positions in the futures market are observed,

Multidimensional Observability Assessment Framework for Optical Autonomous Spacecraft Navigation System

open access: yesGuidance, Navigation and Control
Traditional observability analysis has failed to consider the system-level impact of measurement information acquisition and environmental resource allocation on system states, thereby posing challenges to the design and optimization of spacecraft ...

Controllability and Observability of Fractional Linear Systems with Two Different Orders

open access: yesThe Scientific World Journal, 2014
This paper is concerned with the controllability and observability for a class of fractional linear systems with two different orders. The sufficient and necessary conditions for state controllability and state observability of such systems are ...

Observing the Observers

open access: yes, 2020
In this chapter, I reflect on the origins of the Observing Teachers project. I make links to two facets of observer dependence: the dependence of the origins and conduct of the project on the researchers who originated and conducted it; and the methods we adopted and adapted to allow us to position the teachers as observers in the research.

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

open access: yesFEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.
