In order to assess future trends in desk-top publishing (DTP), it is necessary to understand the problems encountered in today's solutions. The environment addressed by this paper is the single-user interactive workstation for a business, technical or publishing professional. A local or shared low-cost printer is assumed. High-quality and high-volume printing is treated as a remote or an external function to which a document can be transferred in machine-readable form.

Impact: Low-cost spay–neuter clinics were first established nearly 50 years ago in response to the numbers of dogs and cats euthanized in animal shelters. Since then, high-quality, high-volume spay–neuter (HQHVSN) clinics have been established throughout the USA and have contributed to a significant reduction in animal euthanasia in shelters. These clinics, specializing in efficient systems and surgical techniques, provide an avenue for clients who cannot afford surgery to sterilize their pets. These clinics have also helped animal shelters with limited financial resources implement spay–neuter prior to adoption policies. Response: The veterinary profession’s reaction to HQHVSN clinics has been mixed; some practitioners question the quality of care provided or fear the loss of clientele, while others recognize the need for such clinics and support their development. Challenges: As veterinary education has become more expensive and veterinary care more sophisticated, the cost of veterinary care, including spay–neuter surgery, has risen. With increasing costs, the numbers of pets that receive little or no veterinary care has increased. Indeed, a 2018 survey by the Access to Veterinary Care Coalition documented that more than 25% of pet-owning households in the USA experienced difficulties obtaining veterinary care for their pets and the most frequent barrier was financial. Aim: This review looks at the reality of HQHVSN clinics and what this means for the private practitioner. By adopting similar systems and techniques that lower the cost of spay–neuter surgery, practitioners could potentially pass on cost savings to clients. Moreover, the same principles may be applied to other aspects of basic care to further address access to care issues.

AbstractThe need for rapid, accurate, and scalable testing systems for COVID-19 diagnosis is clear and urgent. Here, we report a rapid Scalable and Portable Testing (SPOT) system consisting of a rapid, highly sensitive, and accurate assay and a battery-powered portable device for COVID-19 diagnosis. The SPOT assay comprises a one-pot reverse transcriptase-loop-mediated isothermal amplification (RT-LAMP) followed by PfAgo-based target sequence detection. It is capable of detecting the N gene and E gene in a multiplexed reaction with the limit of detection (LoD) of 0.44 copies/μL and 1.09 copies/μL, respectively, in SARS-CoV-2 virus-spiked saliva samples within 30 min. Moreover, the SPOT system is used to analyze 104 clinical saliva samples and identified 28/30 (93.3% sensitivity) SARS-CoV-2 positive samples (100% sensitivity if LoD is considered) and 73/74 (98.6% specificity) SARS-CoV-2 negative samples. This combination of speed, accuracy, sensitivity, and portability will enable high-volume, low-cost access to areas in need of urgent COVID-19 testing capabilities.

The use of low air quality networks has been increasing in recent years to study urban pollution dynamics. Here we show the evaluation of the operational Aburrá Valley’s low-cost network against the official monitoring network. The results show that the PM2.5 low-cost measurements are very close to those observed by the official network. Additionally, the low-cost allows a higher spatial representation of the concentrations across the valley. We integrate low-cost observations with the chemical transport model Long Term Ozone Simulation-European Operational Smog (LOTOS-EUROS) using data assimilation. Two different configurations of the low-cost network were assimilated: using the whole low-cost network (255 sensors), and a high-quality selection using just the sensors with a correlation factor greater than 0.8 with respect to the official network (115 sensors). The official stations were also assimilated to compare the more dense low-cost network’s impact on the model performance. Both simulations assimilating the low-cost model outperform the model without assimilation and assimilating the official network. The capability to issue warnings for pollution events is also improved by assimilating the low-cost network with respect to the other simulations. Finally, the simulation using the high-quality configuration has lower error values than using the complete low-cost network, showing that it is essential to consider the quality and location and not just the total number of sensors. Our results suggest that with the current advance in low-cost sensors, it is possible to improve model performance with low-cost network data assimilation.
