A High-Resolution All-Digital Temperature Sensor with Process Variation Compensation

open access: yes, 2016
In this paper, we propose a high-resolution all-digital complementary metal–oxide semiconductor (CMOS) temperature sensor with a ring oscillator for temperature sensing and power supply immunity, a time amplifier for process variation compensation, and ...

HaG: Hash graph based key predistribution scheme for multiphase wireless sensor networks [PDF]

open access: yes, 2013
Wireless Sensor Networks (WSN) consist of small sensor nodes which operate until their energy reserve is depleted. These nodes are generally deployed to the environments where network lifespan is much longer than the lifetime of a node.

Modelling of Phase Contrast Imaging with X-ray Wavefront Sensor and Partial Coherence Beams

open access: yesSensors, 2020
The Hartmann wavefront sensor is able to measure, separately and in absolute, the real δ and imaginary part β of the X-ray refractive index. While combined with tomographic setup, the Hartman sensor opens many interesting opportunities behind the direct ...

Design of an Embedded CMOS Temperature Sensor for Passive RFID Tag Chips

open access: yesSensors, 2015
This paper presents an ultra-low embedded power temperature sensor for passive RFID tags. The temperature sensor converts the temperature variation to a PTAT current, which is then transformed into a temperature-controlled frequency. A phase locked loop (

Losses Assisted Sensitivity Enhancement in Reflective-Mode Phase-Variation Permittivity Sensors Based on Weakly Coupled Distributed Resonators

open access: yesIEEE Sensors Letters, 2023
This letter demonstrates that losses [including substrate losses and losses in the material under test (MUT)] can be beneficial to boost the sensitivity in one-port reflective-mode phase-variation planar permittivity sensors based on a pair of weakly coupled quarter-wavelength resonators (the sensing elements).

Fully differential electro-mechanical phase locked loop sensor circuit [PDF]

open access: yes, 2013
Embedding a micro-machined sensing element in a closed loop, force feedback system is a technique commonly used to realise high performance MEMS (micro-electro-mechanical systems) sensors due to the advantages of better linearity, increased dynamic range

Measurement of Gas-Liquid Two-Phase Flow in Micro-Pipes by a Capacitance Sensor

open access: yesSensors, 2014
A capacitance measurement system is developed for the measurement of gas-liquid two-phase flow in glass micro-pipes with inner diameters of 3.96, 2.65 and 1.56 mm, respectively. As a typical flow regime in a micro-pipe two-phase flow system, slug flow is

Clinical and Biological Features of Response in Resistant Neuroblastoma to 131I‐Metaiodobenzylguanidine Radiotherapy in the Anti‐GD2 Immunotherapy Era

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background 131I‐metaiodobenzylguanidine (131I‐MIBG) radiotherapy is a key treatment for relapsed and refractory (R/R) neuroblastoma (NB). Patients with R/R disease treated in the modern era are increasingly exposed to anti‐GD2 immunotherapy, which exerts selective pressure and may modify both tumor cell state and microenvironment.

Venous Thromboembolism in Pediatric Bone Sarcoma Patients: A 10‐Year, Single‐Institution Experience Encompassing the COVID‐19 Pandemic

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Osteosarcoma (OS) and Ewing sarcoma (EWS) are the most common primary bone cancers in children, but acute thrombosis is poorly characterized in this population. Our study evaluated the rates of venous thromboembolism (VTE) and associated risk factors in pediatric patients with bone sarcomas treated over a 10‐year period encompassing
