Narrowband-IoT network for asset tracking system

Narrowband-IoT is one of the emerging LPWAN technologies in the market. Traditionally asset tracking employs Global Positioning System (GPS) and General Packet Radio Service (GPRS) connections to send telemetry data to database servers. Compared to GPRS, NB-IoT has a smaller power usage, given proper implementation. This paper discusses NB-IoT implementation in asset tracking applications. Our test includes these parameters: latency, throughput, packet loss, and power usage for both technologies. The result obtained showed that NB-IoT was underperformed in HTTP but in UDP test, NB-IoT showed better power consumption compared to GPRS (0.352 W vs. 0.542 W) even though both have similar uplink throughput (around 350 B/s). From these findings, this new cellular standard is deemed appropriate in the Asset Tracking application, given the correct protocol and architecture.
Future Cardiovascular Disease Risk for Women With Gestational Hypertension: A Systematic Review and Meta‐Analysis

Background Inconsistent findings have been found among studies evaluating the risk of cardiovascular disease for women who have had pregnancies complicated by gestational hypertension (the new onset of high blood pressure without proteinuria during pregnancy). We provide a comprehensive review of studies to quantify the association between gestational hypertension and cardiovascular events in women. Methods and Results We conducted a systematic search of PubMed, Embase, and Web of Science in March 2019 for studies examining the association between gestational hypertension and any cardiovascular event. Two reviewers independently assessed the abstracts and full‐text articles. Study characteristics and the relative risk (RR) of cardiovascular events associated with gestational hypertension were extracted from the eligible studies. Where appropriate, the estimates were pooled with inverse variance weighted random‐effects meta‐analysis. A total of 21 studies involving 3 60 1192 women (127 913 with gestational hypertension) were identified. Gestational hypertension in the first pregnancy was associated with a greater risk of overall cardiovascular disease (RR, 1.45; 95% CI, 1.17–1.80) and coronary heart disease (RR, 1.46; 95% CI, 1.23–1.73), but not stroke (RR, 1.26; 95% CI, 0.96–1.65) or thromboembolic events (RR, 0.88; 95% CI, 0.73–1.07). Women with 1 or more pregnancies affected by gestational hypertension were at greater risk of cardiovascular disease (RR, 1.81; 95% CI, 1.42–2.31), coronary heart disease (RR, 1.83; 95% CI, 1.33–2.51), and heart failure (RR, 1.77; 95% CI, 1.47–2.13), but not stroke (RR, 1.50; 95% CI, 0.75–2.99). Conclusions Gestational hypertension is associated with a greater risk of overall cardiovascular disease, coronary heart disease, and heart failure. More research is needed to assess the presence of a dose–response relationship between gestational hypertension and subsequent cardiovascular disease.

RNA-sensitive N-isopropylacrylamide/vinylphenylboronic acid random copolymer

Random copolymers of N-isopropylacrylamide (NIPA) and 4-vinylphenylboronic acid (VPBA) were obtained by solution polymerization using 2,2'-azobisizobutyronitrile as the initiator in ethanol at 65°C. NIPA-co-VPBA copolymer exhibited both temperature- and pH-sensitivity. Thermally reversible phase transitions were observed both in the acidic and alkaline pH region for the copolymers produced with different VPBA/NIPA feed ratios. The pH dependency of the lower critical solution temperature (LCST) was stronger for the copolymers produced with higher VPBA feed concentrations. RNA was selected as a model biomolecule having vicinal-diol and amino groups that were potentially reactive with the boronic acid groups of NIPA-co-VPBA copolymer. The effect of RNA concentration on the LCST of NIPA-co-VPBA copolymer was investigated in aqueous media at different pHs. Although no significant effect was observed at pH 4, 7 or 10.5, the LCST decreased linearly with increasing RNA concentration at a pH approximately equal to the pK a of boronic acid. This behavior was explained by considering the binding of RNA onto the copolymer chains to occur via two types of complex formation. For the formation of these complexes, the amino and vicinal-diol groups of RNA should react with the boronic acid groups of the copolymer in the tetrahedral anionic form. The results indicated that NIPA-co-VPBA copolymer could be utilized as a new reagent for the determination of RNA concentration in aqueous media. The proposed method was valid for the RNA concentration range of 0-4 g. mL -1 .
Multicultural orientation in clinical supervision: examining impact through dyadic data

ABSTRACT Clinical supervision can support supervisee cultural development through the relationship and preparation for counseling practice. Supervisor modeling of cultural conversations can aid in this development. Using dyadic data to examine how multicultural orientation (MCO) functions in supervision, we found supervisor cultural humility and missed opportunities to discuss culture both predicted the supervisory working alliance. Diverging from research on MCO in counseling, supervisee growth in ethnocultural empathy and cultural behaviors was not traceable to supervisor cultural humility. Finally, a test of correspondence between supervisor and supervisee assessments of cultural behaviors supported critiques that self-ratings contain biases, particularly for novice counselors.
Arsenic-Hypertolerant Pseudomonads Isolated from Ancient Gold and Copper-Bearing Black Shale Deposits

This report describes the comparative characteristics of Pseudomonas strains isolated from Lubin copper mine and Zloty Stok gold mine in SW Poland. The 9 isolates exhibited huge resistance to arsenic, being able to grow in the presence of 500 mM arsenate and 15 mM arsenite. All strains have evolved strong resistance mechanisms supported by arsenate reduction, but none could utilize arsenite or arsenate in respiratory processes. In addition, these Pseudomonads produced siderophores during growth on medium lacking free iron, which could promote mineral dissolution and mobilization of the more toxic As(III) species in the environment.
Affective Disclosure of Value: emotional experience, neo-sentimentalism and learning to value

Abstract The aim of this paper is to motivate and solve a puzzle regarding the intuition that just as in the absence of perceptual experience we lack an important kind of understanding of sensory properties like colour, in the absence of affective experience we lack an important kind of understanding of value. The puzzle consists in understanding how can a property pertaining to the experience of the subject i.e. the affective component of emotional experience, provide us with a distinctive epistemic access to, and therefore an understanding of, properties that are instantiated by objects distinct from the experience i.e. the evaluative property of the object of experience. I argue that solving the puzzle necessitates us to commit to a metaphysical view of value according to which affective experience and evaluative properties are related by explanatory circularity. The upshot of the paper is that affective experience provides us with the sort of understanding of value that motivates the generation of evaluative concepts.
A Comprehensive Comparative Phylogenomics and Demographic Evolutionary History of the SARS-CoV-2

A new form of beta coronavirus called severe acute respiratory disease coronavirus type 2 (SARS-CoV-2) causing a recent pandemic outbreak possesses a linear positive ss-RNA genome with a length of 29,903 nt. Here, the genomes of SARS-CoV-2 from 821 samples were characterised for its better understanding of the genomic and evolutionary patterns. The phylogeny of SARS-CoV-2 was reconstructed using concatenated dataset consisting of all peptide encoding sequences under Bayesian Inference (BI) and Maximum Likelihood (ML) approaches. Comparison of all peptide encoding sequences reveals high divergence of amino acid sequences proportional to divergence of nucleotides, indicating that the viral genomic evolution has not been strictly neutral. The most part of the genome was under neutral evolution, however, the specific sites for peptide encoding sequences were evolved under positive selection. As well as providing reliable evidence on transmission routes of the SARS-CoV-2 outbreak, the phylogenetics and network analyses suggest the sample reported from Guangdong province is likely ancestor of the pandemic virus form. The overall substitution rate of SARS-CoV-2 genome was estimated to be 1.65 x 10-3 per site per year, falling within the range for previously reported RNA viruses. Median estimation of tMRCA from Bayesian coalescent analyses corresponds to 10 September 2019. The exponential growth rate (r), doubling time (Td) and R0 were estimated to be 47.43 per year, 5.39 days and 2.72, respectively. These findings convincingly emphasise that the use of more comprehensive genome data improves robustness and also enhances understanding of the demographic history of the outbreak.
Redescription of five Asterocheres species (Copepoda: Siphonostomatoida) and a description of a new species discovered in the collections of the Zoological Museum of Amsterdam

This paper re-examines the type material of five Asterocheres Boeck, 1859 species from the collection of Jan Stock deposited in the Zoological Museum of Amsterdam and describes a new species, Asterocheres hoi. Some taxonomically important appendages of these species are redescribed and illustrated. The most striking discrepancies with the original descriptions have been observed in: (1) the segmentation of antennule, antenna and mandibular palp; (2) the omission of some elements in various oral appendages such as the antenna, maxillule, maxilla and maxilliped; (3) the presence or not of a flaccid element on the maxilla; (4) the length of the siphon and the shape of the stylet. The redescribed species, Asterocheres genodon Stock, 1966, Asterocheres halichondriae Stock, 1966, Asterocheres maxillatus Stock, 1987, Asterocheres proboscideus Stock, 1966 and Asterocheres scutatus Stock, 1966, were also compared with their closest congeners. http://www.zoobank.org/urn:lsid:zoobank.org:pub:1E9F6B4E-ADE0-4A84-91EB-222D391E88D7
Ibuprofen has Synergism with SARS-CoV-2 Infection

Although the outbreak of viral infections among human societies is not an unknown phenomenon, but there is a growing terror due to a lack of drugs and fast global strategy against COVID-19 (Coronavirus disease 2019) [1]. There are many growing speculations about the causes of the fast outbreak, the pathology and fast death related to COVID-19. The last one was recent news from University Clinic of Vienna about possible synergism of SARS-CoV-2 RNA replication and consumption of ibuprofen in patients with high frequency of death consequence (data not published). It means Ibuprofen would be a colleague and synergism agent along with Severe Acute Respiratory Syndrome Coronavirus 2 (SARSCoV-2) on death of patients. Is that true?

1. Annual fluctuations in the percentage of L. saxatilis infected by Cercaria ubiquitoides at Whitstable, Kent, are described. 2. Females are consistently more frequently parasitized than males. 3. At higher shore stations more L. saxatilis are parasitized than at lower shore stations. 4. Possible reasons for the above phenomena are discussed together with the relationship between trematode infection and the reproductive activity of L. saxatilis.
Size, shell–living and carcinization in geographic populations of a hermit crab, Pagurus hirsutiusculus

Carcinization, the evolution of a crab–like morphology, has occurred in many hermit crabs. Pagurus hirsutiusculus hermit crabs exhibit geographic variation in traits associated with carcinization. Measurements derived from image analysis of P. hirsutiusculus specimens from geographic locations along the Pacific coast of North America show that Alaskan specimens: (1) are larger, (2) exhibit reduced snail shell–living, and (3) have relatively broader anterior carapaces than southern Californian specimens. This geographic variation may provide general insight into carcinization and the evolution of shell loss in hermit crabs.
The Flow Characteristics of Supercritical Carbon Dioxide (SC-CO2) Jet Fracturing in Limited Perforation Scenarios

Supercritical carbon dioxide (SC-CO2) jet fracturing is a promising alternative for shale gas fracturing instead of water. However, most studies pay more attention to the fracture generation and ignore the flow characteristic of SC-CO2 jet fracturing in limited perforation scenarios. To accurately explore the flow field in a limited perforation tunnel, a numerical model of a SC-CO2 jet in a limited perforation tunnel before fracture initiation is established based on the corresponding engineering background. The comparison between the numerical simulation and experiments has proved that the model is viable for this type of analysis. By using the numerical method, the flow field of the SC-CO2 jet fracturing is analyzed, and influencing factors are discussed later. The verification and validation show that the numerical model is both reliable and accurate. With the dramatic fluctuating of turbulent mixing in a fully developed region, there is an apparent increase in the CO2 density and total pressure during limited perforation. When the z increases from 10 times r0 to 145 times r0, the velocity on the perforation wall surface would decrease below 0 m/s, resulting in backflow in the perforation tunnel. The structure of the nozzle, including the outlet length and outlet diameters, significantly affects the axial velocity and boosting pressure in the perforation tunnel. The highest total pressure exists when the nozzle length-to-radius ratio is 2. The maximum velocity of the jet core drops from 138.7 to 78 m/s, and the “hydraulic isolating ring” starts disappearing when the radius changes from 1 to 1.5 mm. It is necessary to increase the aperture ratio as much as possible to ensure pressurization but not over 1. Based on a similar theory high-speed photography results clearly show that the SC-CO2 develops to fully jetting in only 0.07 s and a strong mixing exists in the annular region between the jet core and the surroundings, according with the numerical simulation. This study should be helpful for scholars to comprehensively understand the interaction between the SC-CO2 jet and perforation, which is beneficial for studying SC-CO2 fracturing.
Composition and Utilization of Poultry By-Product and Hydrolyzed Feather Meal in Broiler Diets

Abstract The proximate analysis with standard errors of 201 samples of poultry by-product and hydrolyzed feather meal (PBHFM) is presented. The metabolizable energy of this product was determined to be 2708 kcal. /kg . Eight experiments were conducted to investigate the role of PBHFM in the diet of broiler chicks. Experiments 1–3 indicated that 10% PBHFM could replace a protein equivalent amount of soybean meal without deleterious effects. The necessity of lysine supplementation in diets containing adequate methionine was demonstrated in experiments 4–6. In experiment 7 the addition of 10.9% PBHFM which replaced all the soybean meal in the starter diet of chicks when supplemented with methionine and lysine to requirement resulted in equal performance as measured by body weight, feed efficiency, performance index (PI), eviscerated meat ratio (EMR) and % grade A carcasses. Supplementary isoleucine or threonine fed singly or in combination did not stimulate the growth of chicks fed a diet containing 10.9% PBHFM.
Improving energy efficiency in massive MIMO: joint digital beam-steering and tone-reservation PAPR reduction

In this study, the authors propose a novel architecture based on the combination of peak-to-average power ratio (PAPR) reduction with digital beamforming (BF) for mm-wave massive multiple-input multiple-output (MIMO) systems. In order to keep the power amplifiers (PAs) working at the same input back-off thus maximising the system power efficiency, they propose to perform time-domain transmit beam-steering by adding progressive time delays to the signals at each antenna element, while keeping the amplitude weights unitary. They show that these time delays can be obtained with a finite impulse response filter implementation of time-domain fractional delay filter structures such as Lagrange interpolation polynomials. They also introduce an analysis on the PAPR of the interpolated signals, where they derive an upper bound to it and show that its value is similar to that of the signal at the input of the interpolation filters, showing the feasibility of the proposed method. In addition, they present a detailed analysis where they show that a significant reduction in computational complexity is obtained when compared to frequency-domain BF. Simulation results validate that the novel proposed scheme combining PAPR reduction and digital BF offers high-precision beam-steering maintaining reduced PAPR in the delayed signals fed to the antennas.
Interferon‐β up‐regulates the expression of co‐stimulatory molecules CD80, CD86 and CD40 on monocytes: significance for treatment of multiple sclerosis

Interferon (IFN)‐β reduces the biological activity of multiple sclerosis (MS), a presumably T cell‐mediated autoimmune disease of central nervous system (CNS) myelin. Co‐stimulatory molecules are necessary for full T cell activation and differential expression of co‐stimulatory molecules on antigen‐presenting cells is thought to influence the type of effector T cell response (Th1/Th2). In this study we investigated the effects of IFN‐β on the expression of co‐stimulatory molecules on lymphocytes and monocytes as a potential mechanism of action of IFN‐β in MS. Peripheral blood mononuclear cells (PBMCs) were stimulated with IFN‐β in vitro and expression of CD80, CD86, CD40 and HLA was examined by flow cytometry and reverse‐transcription polymerase chain reaction. Whereas IFN‐β had no effect on the expression of these molecules on T and B lymphocytes there was a significant increase on monocytes. Correspondingly, the expression of mRNA increased after 6–18 h. This in vitro response was also observed in untreated MS patients and patients receiving treatment with IFN‐β. The increase of co‐stimulatory molecules on monocytes was not mediated by interleukin (IL)‐10. When IFN‐β‐stimulated monocytes were used to stimulate autologous T cells an increased secretion of IL‐13 was observed. In biopsies taken from IFN‐β‐induced skin reactions after subcutaneous injection increased expression of CD80 mRNA was detected, indicating that IFN‐β also up‐regulates this co‐stimulatory molecule in vivo. These data provide the background for further studies of IFN‐β‐induced changes of co‐stimulatory molecules in MS patients.
Decline and demographic changes in the population of the Near Threatened brown lemur Eulemur fulvus on Mayotte

Abstract The population of the Near Threatened brown lemur Eulemur fulvus on the island of Mayotte was censused in 1974, 1984 and 1999. We carried out a new census in 2008, estimating individual and group densities in the three main habitat types on the island (preserved forest, anthropogenic forest and agricultural areas), and more generally evaluating population trends. Data included sex ratios and the number of young < 1 year-old per female. The census was at the end of the dry season, along 14 transect lines of 0.5 or 1 km length. Counts of groups and individuals were repeated three times between 07.00 and 10.00 and between 15.00 and 18.00. The densities of groups and individuals were calculated using Distance. By 2008 group and individual densities had significantly decreased in preserved forest, and there was also a decrease in group size in all habitat types. The 2008 census also showed that the overall population of E. fulvus on Mayotte has decreased by about half since 1999. We suggest that these changes reflect environmental stress associated with a decrease in available food resources. Urgent action to preserve forest habitat is necessary for the long-term survival of this lemur.
Escherichia coli pH 2.5 acid phosphatase and β-lactamase TEM2 are secreted into the medium by Myxococcus xanthus

The genes appA, coding for the periplasmic pH 2.5 acid phosphatase of Escherichia coli, and bla, borne by Tn1 coding for TEM2 β-lactamase, another periplasmic enzyme in Gram-negative bacteria, have been transferred and expressed in Myxococcus xanthus. The specified enzymes could be recovered from both cells and extracellular fluid. The pH 2.5 acid phosphatase was expressed in the same way as genuine extracellular proteins in Myxococcus. This activity was recovered throughout exponential growth and was modulated by mutations that affected he total amount of extracellular proteins. A possible mechanism for protein secretion in Myxococcus is discussed in view of these results.

Linear Correction and Matching Method for 3D Line Structure Reconstruction

The 3D reconstruction technique using the straight-line segments as features has high precision and low computational cost. The method is especially suitable for large-scale urban datasets. However, the line matching step in the existing method has a mismatching problem. The two main reasons for this problem are the line detection result is not located at the true edge of the image and there is no consistency check of the matching pair. In order to solve this problem, a linear correction and matching method for 3D reconstruction of target line structure is proposed in this paper. Firstly, the edge features of the image are extracted to obtain a binarized edge map. Then, the extended gradient map is calculated using the edge map and the gradient to establish the gradient gravitational map. Secondly, the straight-line detection method is used to extract all the linear features used for the 3D reconstruction image, and the linear position is corrected by the gradient gravitational map. Finally, the point feature matching result is used to calculate the polar line, and the line matching results of the adjacent three images are used to determine the final partial check feature area. Then, random sampling is used to obtain the feature similarity check line matching result in the small neighborhood. The aforementioned steps can eliminate the mismatched lines. The experimental results demonstrate that the 3D model obtained using the proposed method has higher integrity and accuracy than the existing methods.
