Bayesian changepoint analysis for atomic force microscopy and soft material indentation

open access: yes, 2008
Material indentation studies, in which a probe is brought into controlled physical contact with an experimental sample, have long been a primary means by which scientists characterize the mechanical properties of materials.

A 24-GHz CMOS Front-End [PDF]

open access: yes, 2004
This paper reports the first 24-GHz CMOS front-end in a 0.18-µm process. It consists of a low-noise amplifier (LNA) and a mixer and downconverts an RF input at 24GHz to an IF of 5 GHz.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Particle identification

open access: yes, 2011
Particle IDentification (PID) is fundamental to particle physics experiments. This paper reviews PID strategies and methods used by the large LHC experiments, which provide outstanding examples of the state-of-the-art.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Correlation of plasma renin activity values and resistive index on ultrasound doppler with findings of renal dynamic scan in patients with the society of fetal ultrasound grades 3 and 4 unilateral hydronephrosis

open access: yesJournal of Indian Association of Pediatric Surgeons, 2022
Background: Renal dynamic scans (RDS) despite being considered the gold standard for the diagnosis of pelvic ureteric junction obstruction (PUJO), fail to help resolve the dilemma about management issues in many patients.

Very High Order $\PNM$ Schemes on Unstructured Meshes for the Resistive Relativistic MHD Equations

open access: yes, 2009
In this paper we propose the first better than second order accurate method in space and time for the numerical solution of the resistive relativistic magnetohydrodynamics (RRMHD) equations on unstructured meshes in multiple space dimensions.

Three-dimensional fast electron transport for ignition-scale inertial fusion capsules [PDF]

open access: yes, 2006
Three-dimensional hybrid PIC simulations are presented to study electron energy transport and deposition in a full-scale fast ignition configuration. Multi-prong core heating close to ignition is found when a few GA, few PW beam is injected.

Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Value of Cranial Ultrasonography and Resistive Index of Cerebral Arteries in Predicting Neuromotor Outcomes in Newborns with Hypoxic Ischaemic Encephalopathy [PDF]

open access: yesIndian Journal of Neonatal Medicine and Research, 2018
Introduction: Perinatal asphyxia is one of the leading cause of neonatal mortality and childhood morbidity. Use of cranial Ultrasonography (USG) and cranial arterial doppler indices has been evaluated for predicting risk of neuromotor impairment ...
