Exploring the full spectrum of macrophage activation

open access: yesNature reviews. Immunology, 2008
Macrophages display remarkable plasticity and can change their physiology in response to environmental cues. These changes can give rise to different populations of cells with distinct functions.

Augmentative and alternative communication for children with autism spectrum disorder: An evidence-based evaluation of the Language Acquisition through Motor Planning (LAMP) programme

open access: yesCogent Education, 2015
Children diagnosed with autism spectrum disorder often have restricted verbal communication. For children who do not use functional speech, augmentative and alternative communication (AAC) devices can be an important support.

Spectrum Patrolling With Crowdsourced Spectrum Sensors

open access: yesIEEE Transactions on Cognitive Communications and Networking, 2020
We use a crowdsourcing approach for RF spectrum patrolling, where heterogeneous, low-cost spectrum sensors are deployed widely and are tasked with detecting unauthorized transmissions while consuming only a limited amount of resources. We pose this as a signal detection problem where the individual sensor’s detection performance may vary widely based ...

On the Rationality of the Spectrum

open access: yesJournal of Fourier Analysis and Applications, 2017
Let $Ω\subset \mathbb{R}$ be a compact set with measure $1$. If there exists a subset $Λ\subset \mathbb{R}$ such that the set of exponential functions $E_Λ:=\{e_λ(x) = e^{2πi λx}|_Ω:λ\in Λ\}$ is an orthonormal basis for $L^2(Ω)$, then $Λ$ is called a spectrum for the set $Ω$.

Axillary metastases after port site recurrences of gallbladder carcinoma: a case report

open access: yesWorld Journal of Surgical Oncology, 2020
Background Incidental gallbladder carcinoma is often discovered after elective laparoscopic cholecystectomy for cholecystitis or cholecystolithiasis. Port site recurrences may occur. Patients with port site metastases of gallbladder carcinoma have a poor

On the spectrum of silicon; with a note on the spectrum of fluorine [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1905
Abstract In a recent paper M. A. de Gramont questions the silicon origin of certain lines, viz.: λ 4089·1, λ 4096·9, and λ 4116·4, grouped together as Group IV by Sir Norman Lockyer who ascribes them to the element named. He says: “J’ajouterai que les lignes du groupe IV, qui indiqueraient, d’aprés Lockyer, une température excessive ...

WEARCON: wearable home monitoring in children with asthma reveals a strong association with hospital based assessment of asthma control

open access: yesBMC Medical Informatics and Decision Making, 2020
Background Asthma is one of the most common chronic diseases in childhood. Regular follow-up of physiological parameters in the home setting, in relation to asthma symptoms, can provide complementary quantitative insights into the dynamics of the asthma ...
