The most salient problems of transit vehicle service in Latin American intermediate cities include:the high number of passengers involved in traffic accidents;traffic congestion caused by transit vehicles,and pollution generated by these vehicles,which increases in high congestion scenarios.To improve upon this situation,a research was conducted on the transit vehicle tracking service,which is a basic service for implementing mobility solutions for the aforementioned problems,the most relevant characteristics of this service for the context of Latin American intermediate cities were identified,and an implementation was proposed.This paper presents the four stages of the study:(a)a review of the state-of-the-art of services or systems related to vehicle tracking,including wireless communications technologies,implemented sustainability approaches,usage of special algorithms for efficiency improvement,and the intelligent transportation system(ITS)architecture used as a basis;(b)the process of identifying relevant characteristics of the service for a given context;(c)proposal of an ITS architecture for this service in an intermediate city,its requirements and the suggested technologies;and(d)development of experiments for validating usage of the key suggested technologies.The review allowed to identify the main service characteristics,with regard to vehicle positioning technologies,the recommended wireless communication technology(long range,LoRa),energy consumption considerations,and use of artificial intelligence(AI)to calculate waiting time of users at bus stops.Finally,an ITS architecture for the city of Popayan(Colombian city)considering the aforementioned characteristics is proposed,and the experiments related to the use of these technologies are described in detail.

The control of gene expression by transcriptional regulators and other types of functional y relevant DnA transactions such as chromatin remodeling and replication underlie a vast spectrum of biological processes in al organisms. DnA transactions require the control ed interaction of proteins with DnA sequence motifs which are often located in nucleosome-depleted regions （nDRs） of the chromatin. Formaldehyde-assisted isolation of regulatory elements （FAIRE） has been established as an easy-to-implement method for the isolation of nDRs from a number of eukaryotic organisms, and it has been successful y employed for the discovery of new regulatory segments in genomic DnA from, for example, yeast, Drosophila, and humans. Until today, however, FAIRE has only rarely been employed in plant research and currently no detailed FAIRE protocol for plants has been published. Here, we provide a step-by-step FAIRE protocol for nDR discovery in Arabidopsis thaliana. We demonstrate that nDRs isolated from plant chromatin are readily amenable to quantitative polymerase chain reaction and next-generation sequencing. Only minor modification of the FAIRE protocol wil be needed to adapt it to other plants, thus facilitating the global inventory of regulatory regions across species.

Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components.Dendritic cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFn-α).In COVID-19 there is a deficit in DC numbers and IFn-αproduction,which has been associated with disease severity.In this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory markers.Remarkably,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 infection.Moreover,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were observed.These findings contribute to a better understanding of the immunological sequelae of COVID-19.

Traffic accidents are one of the most serious problems worldwide,being one of the leading causes of death and economic loss in the world.Low-and middle-income countries,mainly their medium-sized cities,are among the most affected by this problem.93%of traffic accidents occur in low and middle-income countries,even though these countries have approximately 60%of the world’s vehicles.This occurs mainly because in these types of countries,especially in medium-sized cities(target context),there are no ideal conditions for driving,such as adequate road infrastructure,good condition of vehicles,and rigorous safety policies.Advanced data analysis techniques including machine learning(ML)have increasingly been used to solve this problem.naturalistic driving(nD)can be applied as a data collection method that provides information on traffic accidents.nD commonly uses a vehicle’s kinematic data to detect high-risk driving behaviors that could cause an accident.The objectives of this document are to present a review of different alternatives that help in data collection and creation of intelligent solutions related to detection of possible traffic accidents,principally using nD;and to propose an intelligent collision risk detection system(ICRDS)for identification of areas with a high probability of TA in the target context.Through the review,it was possible to analyze and evaluate the devices,variables and algorithms that help characterize a risk event in driving,considering the target context.The development of a prototype of an ICRDS for a medium-sized city in a developing country is considered viable,considering the identified components,with the aim of identifying risk events in driving,and areas of high probability of accidents in the city.

The influence of emissions of an active volcano on the composition of nanoparticles and ultrafine road dust was identified in an urban area of the Andes.Although many cities are close to active volcanoes,few studies have evaluated their influence in road dust composition.Air quality in urban areas is significantly affected by nonexhaust emissions(e.***.road dust,brake wear,tire wear),however,natural sources such as volcanoes also impact the chemical composition of the particles.In this study,elements from volcanic emissions such as Si>Al>Fe>Ca>K>Mg,and Si-Al with K were identified as complex hydrates.Similarly,As,Hg,Cd,Pb,As,H,Cd,Pb,V,and salammoniac were observed in nanoparticles and ultrafine material.Mineral composition was detected in the order of quartz>mullite>calcite>kaolinite>illite>goethite>magnetite>zircon>monazite,in addition to salammoniac,a tracer of volcanic sources.The foregoing analysis reflects the importance of carrying out more studies relating the influence of volcanic emissions in road dust in order to protect human health.The road dust load(RD_(10))ranged between 0.8 and 26.8 mg m^(−2)in the city.

Background: Chinese medical diagnoses and treatment recommendations for specific patients with chronic low back pain vary widely across practitioners.A comparison of individualized treatment with a thoughtfully developed standardized approach is useful to determine which, if either, is superior.Objective: We aimed to compare the effectiveness of standardized and individualized acupuncture treatment in patients with chronic low back pain.Methods: We performed a single-centre randomized controlled single-blind trial in a general medical practice in Germany run by a Chinese born medical doctor trained in Western and Chinese medicine.150 outpatients with chronic low back pain were randomly allocated to two groups(78 standardized acupuncture and 72 individualized acupuncture).Patients received either standardized acupuncture or individualized acupuncture.Treatment encompassed between 10 to 15 treatments based on individual symptoms with two treatments per week.The main outcome measure was the area under the curve(AUC), summarizing eight weeks of daily rated pain severity measured with a visual analogue scale(0 mm=no pain, 100 mm=worst imaginable pain).Results: no significant differences between groups were observed for the AUC(individualized acupuncture mean:1768.7 [95% CI, 1460.4; 2077.1]; standardized acupuncture 1482.9 [1177.2; 1788.7]; group difference, 285.8 [-33.9; 605.5] P=0.080).Conclusion: In this single-centre trial individualized acupuncture was not superior to standardized acupuncture for patients suffering from chronic pain.As a next step a multi-centre non-inferiority study should be performed to investigate whether standardized acupuncture treatment for chronic low back pain might be applicable in a broader usual care setting.
