The Cost

Animal location technologies have evolved considerably in the last 60 years. Nowadays, animal tracking solutions based on global positioning systems (GPS) are commercially available. However, existing devices have several constraints, mostly related to wireless data transmission and financial cost, which make impractical the monitorization of all the animals in a herd. The main objective of this work is to develop a low-cost solution to enable the monitorization of a whole herd. An IoT-based system, which requires some animals of the herd being fitted with GPS collars connected to a Sigfox network and the rest with low-cost Bluetooth tags, has been developed. Its performance has been tested in two commercial farms, raising sheep and beef cattle, through the monitorization of 50 females in each case. Several collar/tag ratios, which define the cost per animal of the solution, have been simulated. Results demonstrate that a low collar/tag ratio enable the monitorization of a whole sheep herd. A larger ratio is needed for beef cows because of their grazing behavior. Nevertheless, the optimal ratio depends on the purpose of location data. Large variability has been observed for the number of hourly and daily messages from collars and tags. The system effectiveness for the monitorization of all the animals in a herd has been certainly proved.

<p>The collective term ‘Internet of Things’ (IoT) encompasses a variety of technologies and methods providing novel opportunities for data acquisition and control in environmental sciences. Availability of cost effective components as well as support of large open source communities allow scientists to gain more flexibility and control over their experimental setups. However quality of measurements, stability of instruments as well as real costs for development and maintenance are often underestimated challenges. The presentation introduces current best practices of IoT principles in scientific applications. Examples of low cost sensors, low power electronics, wireless data transmission protocols, time series databases as well as real-time visualization are presented and discussed. Furthermore light is shed on non-technological issues of the ‘do-it-yourself’ or ‘maker’ approach such as social and psychological aspects. The ‘make-share-learn’ paradigm of the maker culture can be utilized to raise awareness. It provides significant opportunities for environmental education and community building which constantly gain more importance in the context of climate and environmental change.</p>

As an important means to protect water resources, water quality detection is of great social and economic significance. Water quality detection sensors processed by micro-electro-mechanical system (MEMS) technology have the advantages of low-cost, small size, and high sensitivity. In this paper, a multi-parameter water quality detection integrated sensor chip is further studied, and a portable detection system using this chip is developed. Temperature, pH, oxidation-reduction potential (ORP), conductivity and concentration of copper ions (Cu2+) are selected as typical water quality parameters. Experiments of sensor calibrations using this portable detection system were performed in standard solutions. The sensor has a sensitivity of −57.34 mV/pH in pH detection and 5.95 Ω/°C in temperature response. ORP is directly detected by Pt microelectrode on the chip and the relative error is less than 3%. The electrode constant of the sensor is 1.416 cm−1 and the linearity is 0.9995 in conductivity detection. With the gold nanoparticles deposited on the electrode, the detection peak of Cu2+ appears at 280 mV and the sensor shows good linearity to the concentration of Cu2+ in the range of 0–0.6 mg/L. The detection limit of Cu2+ concentration is 2.33 μg/L. Through measurement and calculation, the accuracy of the portable system is within 4%. This portable multi-parameter water quality detection system with the MEMS-based integrated chip shows great potential in the field and fast detection.

Abstract BACKGROUND Current liquid-based cancer screening relies on massive deep NGS to detect rare cancer-derived genetic materials - a costly method fraught with high false-negative and false-positive rates. We aim to develop a non-NGS-centered, AI-directed liquid-based detection of GBM stem-like cells (GSCs). METHODS Utilizing a robust AI suite, NETZEN, we defined a common master regulatory gene network (MRGN) of the GBM state in GSCs. Since master regulators (MRs) in MRGN are developmentally restricted, their chromosomal loci are accessible in GSCs but not in normal cells. Downstream factors in MRGN are massively overexpressed in GSCs compared to normal cells. Thus, we measured the following in PBMCs from healthy controls spiked with known quantities of GSCs and patients with GBM: 1) accessibility of MR genes using transposase/transposons carrying unique barcodes to be inserted into the MR’s predetermined accessible locations, and 2) expression of downstream factors using nested qRT-PCR. RESULTS We characterized 10 MRs in GSCs with ≥1 promoter region that is hypomethylated and accessible (by ATACseq) in GBM/GSCs per GSE70175-92460 (19 samples) and GSE67633-96088 (14 samples), or hypermethylated and inaccessible in lymphocytes/PBMCs per GSE98837 (6) and GSE74912 (13). Using barcoded transposons, we specifically disrupted 4 MR’s accessible foci only in GSCs, not in PBMCs. We also identified 50 downstream factors with the top 20 having 3 to 5-orders-of-magnitude higher mean expression in GSCs compared to PBMCs (GSE79362-86884, 451 samples). Currently our method has a detection limit of 0.2-1 GSC per 106 PBMCs. Using the first iteration, we detected MRGN of the GBM state in blood samples of 14 of 14 GBM patients before resection, compared to none of 15 healthy donors. CONCLUSIONS Chromosomal accessibility and signal amplification in MRGN of GSCs provide powerful substrates for a non-NGS, low-cost, liquid-based GBM detection system with high sensitivity and specificity. Further testing and optimization are ongoing.
