Cyberattacks on Primary Frequency Response Mechanisms in Power Grids

Computer, 2018
Primary frequency response (PFR) is an important mechanism for making power grids resilient to faults that could lead to outages. We present the first study of cyberattacks that could cause power outages by infiltrating operational technology networks in generation control systems to inhibit the PFR.

Battery storage configuration for multi-energy microgrid considering primary frequency regulation and demand response

Energy Reports, 2022
In this paper, we study the optimal configuration problem of battery energy storage (BES) for multi-energy microgrid (MEMG) in two typical modes, which considers demand response in grid-connected mode and primary frequency regulation in islanding mode ...

Stereotactic Body Radiation Therapy for Pediatric, Adolescent, and Young Adult Patients With Osteosarcoma: Local Control Outcomes With Dosimetric Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Osteosarcoma is a radioresistant tumor that may benefit from stereotactic body radiation therapy (SBRT) for locoregional control in metastatic/recurrent disease. We report institutional practice patterns, outcomes, toxicity, and failures in osteosarcoma patients treated with SBRT.

Excitation of multiple 2-mode parametric resonances by a single driven mode

, 2017
We demonstrate autoparametric excitation of two distinct sub-harmonic mechanical modes by the same driven mechanical mode corresponding to different drive frequencies within its resonance dispersion band. This experimental observation is used to motivate

Frequency resolved spectroscopy of Cyg X-1: fast variability of the reflected emission in the soft state [PDF]

, 2000
Using the RXTE/PCA data we study the fast variability of the reflected emission in the soft spectral state of Cyg X-1 by means of Fourier frequency resolved spectroscopy. We find that the rms amplitude of variations of the reflected emission has the same

Optimizing DER Participation in Inertial and Primary-Frequency Response

2019 IEEE Power & Energy Society General Meeting (PESGM), 2018
This paper develops an approach to enable the optimal participation of distributed energy resources (DERs) in inertial- and primary-frequency response alongside conventional synchronous generators. Leveraging a reduced-order model description of frequency dynamics, DERs’ synthetic inertias and droop coefficients are designed to meet time-domain ...

Lifestyle Behaviors and Cardiotoxic Treatment Risks in Adult Childhood Cancer Survivors

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Higher doses of anthracyclines and heart‐relevant radiotherapy increase cardiovascular disease (CVD) risk. This study assessed CVD and CVD risk factors among adult childhood cancer survivors (CCSs) across cardiotoxic treatment risk groups and examined associations between lifestyle behaviors and treatment risks.

Combining frequency and time domain approaches to systems with multiple spike train input and output [PDF]

, 2009
A frequency domain approach and a time domain approach have been combined in an investigation of the behaviour of the primary and secondary endings of an isolated muscle spindle in response to the activity of two static fusimotor axons when the parent ...

Shake table testing of a tuned mass damper inerter (Tmdi)-equipped structure and nonlinear dynamic modeling under harmonic excitations [PDF]

, 2020
This paper presents preliminary experimental results from a novel shaking table testing campaign investigating the dynamic response of a two-degree-of-freedom (2DOF) physical specimen with a grounded inerter under harmonic base excitation and contributes

Changes in Body Composition in Children and Young People Undergoing Treatment for Acute Lymphoblastic Leukemia: A Systematic Review and Meta‐Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.
