Monitoring and assessment for obstructive sleep apnea

FlexMat, EarlyView.
This review systematically classifies Obstructive Sleep Apnea (OSA) monitoring indicators into three categories: physical, biochemical, and electrophysiological indicators, and lists several methods for each category. Abstract Obstructive sleep apnea (OSA) is a common chronic sleep‐disordered breathing disease characterized by recurrent upper airway ...

Stripping‐based approach for the recovery of volatile fatty acids from anaerobic digestion digestate: preliminary experimental investigations and modelling

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Volatile fatty acids (VFAs) are widely used across industries: as intermediates in chemical production (e.g., solvents and polymers), in pharmaceuticals and cosmetics, and as preservatives and health‐promoting additives in food and animal feed. Emerging applications also include bioplastics, bioenergy, and biotechnology.

Counter‐factual simulation highlights requirements for additional management to avert extinction of a relict Tītī/Sooty Shearwater population

Ibis, EarlyView.
Seabirds play key ecological roles but face increasing threats worldwide. Among them, Tītī (Sooty Shearwater) Ardenna grisea are among the most abundant and culturally significant species in the Southern Hemisphere but are also threatened. Kapiti Island, Aotearoa (New Zealand), holds a Tītī colony which, despite eradication of non‐native mammalian ...

Numerical Investigation of the Time Discretization Impact on the Accuracy of a Point Target Localization by UWB Radar

EPJ Web of Conferences, 2018
UWB radar technologies enable localization of moving persons (targets) situated behind nonmetallic obstacles. Under exact knowledge of the propagation times, from the transmitting to the receiving antennas, of the radar emitted electromagnetic wave (time

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

Journal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Comparison of different X‐ray‐based scanning electron microscopy methods to detect sub‐nanometre ultra‐thin InAs layers deposited on top of GaAs

Journal of Microscopy, EarlyView.
Abstract We compare three different methods of X‐ray analysis in a scanning electron microscope (SEM): energy‐dispersive X‐ray spectroscopy (EDX), wavelength‐dispersive X‐ray spectroscopy (WDX) and micro X‐ray fluorescence (μXRF). These methods are all applied to the same gallium arsenide (GaAs) wafer with a 0.8 nm layer of indium arsenide (InAs) on ...

Determining bismuth content in GaAsBi alloys by energy‐dispersive X‐ray spectroscopy: A case study with multiple sets of k*‐factors for analytical transmission electron microscopy

Journal of Microscopy, EarlyView.
Abstract Measuring the bismuth (Bi) content of ternary gallium arsenide bismuthide (GaAsBi) alloys is important because it sensitively influences their bandgap, and Bi is known to segregate vertically to the surface and sometimes also laterally during growth, so elemental distribution maps need to be quantified.

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

Journal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

A Review of Linear Multilateration Techniques and Applications

IEEE Access
In multilateration, distances between an unknown location and several known points are used to determine the location of the unknown point. Papers on algorithms for multilateration, such as time of arrival (TOA), time difference of arrival (TDOA), and ...

Time of Arrival Based on Chirp Pulses as a means to Perform Localization in IEEE 802.15.4a Wireless Sensor Networks

Advances in Electrical and Computer Engineering, 2010
This paper introduces the technology Time of Arrival (TOA) based on chirp pulses (according to IEEE 802.15.4a) as a means to perform localization in Wireless Sensor Networks (WSN's) active at 2.4 GHz.
