AbstractBackgroundRhipicephalus microplus, an invasive tick species of Asian origin and the main vector ofBabesiaspecies, is considered one of the most widespread ectoparasites of livestock. The tick has spread from its native habitats on translocated livestock to large parts of the tropical world, where it has replaced some of the local populations ofRhipicephalus decoloratusticks. Although the tick was reported in Uganda 70 years ago, it has not been found in any subsequent surveys. This study was carried out to update the national tick species distribution on livestock in Uganda as a basis for tick and tick-borne disease control, with particular reference toR. microplus.MethodsThe study was carried out in Kadungulu, Serere district, south-eastern Uganda, which is dominated by small scale livestock producers. All the ticks collected from 240 cattle from six villages were identified microscopically. FiveR. microplusspecimens were further processed for phylogenetic analysis and species confirmation.ResultsThe predominant tick species found on cattle wasRhipicephalus appendiculatus(86.9 %;n= 16,509). Other species found wereAmblyomma variegatum(7.2 %;n= 1377),Rhipicephalus evertsi(2.3 %;n= 434)andR. microplus(3.6 %;n= 687). Phylogenetic analysis of the12SrRNA,16SrRNA and ITS2 gene sequences ofR. microplusconfirmed the morphological identification.ConclusionsIt is concluded thatR. microplushas replacedR. decoloratusin the sampled villages in Kadungulu sub-county, since the latter was not any longer found in this area. There is currently no livestock movement policy in force in Uganda, which could possibly limit the further spread ofR. microplusticks. Future surveys, but also retrospective surveys of museum specimens, will reveal the extent of distribution ofR. microplusin Uganda and also for how long this tick has been present on livestock without being noticed.
Energy-efficient renewable scheme for rechargeable sensor networks
Authors: Zhang Qian , Cheng Rong , Zheng Zhihua 
Published: April 2020

AbstractWireless energy transfer (WET) is a promising technology to fundamentally settle energy and lifetime problems in a wireless sensor network (WSN). In this paper, we study the operation of WSN based on WET using a mobile charging vehicle (MCV) and construct a periodic strategy to make the network operational permanently. Our goal is to decrease energy consumption of the entire system while maintaining the network operational forever. Based on the analysis of total energy consumption, we propose an energy-efficient renewable scheme (ERSVC) to achieve energy saving. Compared to previous schemes where the MCV visits and charges all nodes in each cycle, the MCV only needs to visit a portion of nodes in ERSVC. Numerical results show that our scheme can significantly decrease the total energy consumption with no performance loss. It is also validated that ERSVC can maintain the network operational forever with lower complexity than other schemes, making it more practical for real networks.
Combined CT texture analysis and nodal axial ratio for detection of nodal metastasis in esophageal cancer
Authors: Lee Han Na , Kim Jung Im , Shin So Youn , Kim Dae Hyun , Kim Chanwoo , Hong Il Ki 
Published: April 2020

Objective:
To assess the accuracy of a combination of CT texture analysis (CTTA) and nodal axial ratio to detect metastatic lymph nodes (LNs) in esophageal squamous cell carcinoma (ESCC).

Methods:
The contrast-enhanced chest CT images of 78 LNs (40 metastasis, 38 benign) from 38 patients with ESCC were retrospectively analyzed. Nodal axial ratios (short-axis/long-axis diameter) were calculated. CCTA parameters (kurtosis, entropy, skewness) were extracted using commercial software (TexRAD) with fine, medium, and coarse spatial filters. Combinations of significant texture features and nodal axial ratios were entered as predictors in logistic regression models to differentiate metastatic from benign LNs, and the performance of the logistic regression models was analyzed using the area under the receiver operating characteristic curve (AUROC).

Results:
The mean axial ratio of metastatic LNs was significantly higher than that of benign LNs (0.81 ± 0.2 vs 0.71 ± 0.1, p = 0.005; sensitivity 82.5%, specificity 47.4%); namely, significantly more round than benign. The mean values of the entropy (all filters) and kurtosis (fine and medium) of metastatic LNs were significantly higher than those of benign LNs (all, p &lt; 0.05). Medium entropy showed the best performance in the AUROC analysis with 0.802 (p &lt; 0.001; sensitivity 85.0%, specificity 63.2%). A binary logistic regression analysis combining the nodal axial ratio, fine entropy, and fine kurtosis identified metastatic LNs with 87.5% sensitivity and 65.8% specificity (AUROC = 0.855, p &lt; 0.001).

Conclusion:
The combination of CTTA features and the axial ratio of LNs has the potential to differentiate metastatic from benign LNs and improves the sensitivity for detection of LN metastases in ESCC.

Advances in knowledge:
The combination of CTTA and nodal axial ratio has improved CT sensitivity (up to 87.5%) for the diagnosis of metastatic LNs in esophageal cancer.
Thin thermally grown oxide thickness detection in thermal barrier coatings based on SWT-BP neural network algorithm and terahertz technology
Authors: Luo Manting , Zhong Shuncong , Yao Ligang , Tu Wanli , Nsengiyumva Walter , Chen Weiqiang 
Published: April 2020

Terahertz time-domain spectroscopy is a contactless and nondestructive testing technique that is often used to measure the thickness of layered materials. However, the technique presents limited thickness detection resolution, especially in the thin thermally grown oxide (TGO) of thermal barrier coatings whose thickness is below 30 µm. In this study, an SWT-BP algorithm combining a stationary wavelet transform (SWT) and a backpropagation (BP) neural network was proposed, and the regression coefficient of SWT-detailed results was 0.92. The prediction results were in good agreement with the real-time results; it demonstrated that the proposed algorithm was able to achieve a thickness prediction of up to 1–29 µm of the TGO. The proposed algorithm is suitable for thin thickness detection of the TGO.
Artifacts related to cone beam computed tomography technology (CBCT) and their significance for clinicians: illustrated review of medical literature.
Authors: Olszewski Raphael 
Published: April 2020

Objective: to explain the meaning and to illustrate technical artifacts (aliasing as well as the ring artifact) and beam hardening (metal artifact) that can be present in the dentomaxillofacial cone beam computed tomography (CBCT), and to check the accessibility of free illustrations of these artifacts in medical publications.
Material and methods: One observer applied five search equations using database PubMed. The exclusion criteria were: experimental studies, animal studies, studies not related to dentomaxillofacial area, and articles with closed access. There was no time limit for the search of articles. We limited our search to English and French language.
Results: Only 3 articles out of 434 publications were retained after application of inclusion/exclusion criteria. In these articles only 4 annotated figures were freely accessible in medical publications from PubMed.
In this paper we presented examples of aliasing, ring artifact, and beam artifacts from I-CAT, Carestream 9000 3D (Kodak), and Planmeca Promax 3D Mid CBCT. The intensity of beam hardening artifact varies from major degradation of image (i.e., subperiosteal implants, bridges, crowns, dental implants, and orthodontic fix appliances), through mean degradation (screws securing titanium mesh, head of mini-implant) to no beam hardening on metallic devices (orthodontic anchorage, orthodontic contention wire) or on dense objects (endodontic treatments, impression materials, Lego box). Some beam hardening artifacts arising from nasal piercing, hairs, or hearing aid device may be present on the image but they will not disturb the evaluation of the field of view.
Conclusions: reduction of aliasing artifact is related with the improvement of detectors quality. The presence of ring artifact means that CBCT device has lost its calibration. The field of view (FOV) needs to be reduce in order to avoid scanning regions susceptible to beam hardening (e.g., metallic restorations, dental implants). Finally, the accessibility to open knowledge on technique -related CBCT artifacts seems extremely limited when searching at PubMed database.

Jak učitelé vnímají komunikaci s rodiči: Spokojení vs. vyhořelí
Authors: Viktorová Ida 
Published: April 2020

Abstrakt: V této studii jsme se zaměřili na otázku, jak vidí komunikaci s rodiči učitelé dvou skupin na opačných pólech: spokojení v profesi učitele vs. nespokojení, resp. s rozvíjejícím se syndromem vyhořením. Zkoumali jsme totiž v rámci většího projektu profesní nároky a syndrom vyhoření u učitelů základních škol. Jako jeden ze zdrojů stresu ve škole je často uváděna složitá komunikace mezi aktéry (učitelé, vedení, žáci a rodiče). Vycházeli jsme z 58 rozhovorů s učiteli z různých míst republiky. Výsledky ukázaly velmi rozdílný subjektivní obraz rodičů u těchto dvou skupin. Vyhořelí učitelé mají více konfliktů s rodiči žáků, mnohem hůře je prožívají a obtížněji hledají jejich řešení. Spokojení učitelé jsou realističtější, často konfliktům předcházejí, mají pevnější hranice komunikace a neprožívají problémy osobně, rodičů se nebojí.
Klíčová slova: učitel základní školy, vyhoření, komunikace s rodiči, konflikty s rodiči, řešení konfliktů s rodiči.

Progress towards a rigorous error propagation for total least-squares estimates
Authors: Schaffrin Burkhard , Snow Kyle 
Published: April 2020

Abstract
After several attempts at a formal derivation of the dispersion matrix for Total Least-Squares (TLS) estimates within an Errors-In-Variables (EIV) Model, here a refined approach is presented that makes rigorous use of the nonlinear normal equations, though assuming a Kronecker product structure for both observational dispersion matrices at this point. In this way, iterative linearization of a model (that can be established as being equivalent to the original EIV-Model) is avoided, which might be preferred since such techniques are based on the last iteration step only and, therefore, produce dispersion matrices for the estimated parameters that are generally too optimistic. Here, the error propagation is based on the (linearized total differential of the) exact nonlinear normal equations, which should lead to more trustworthy measures of precision.
Unbleached and bleached handsheet characteristics of Subabul heartwood and sapwood
Authors: Pydimalla Madhuri , Adusumalli Ramesh Babu 
Published: April 2020

Abstract
The objective of this study was to understand the influence of bleaching on % residual lignin, water retention value, brightness and morphological properties of Subabul heartwood and sapwood pulps. The second aim was to compare the properties of unbleached and bleached handsheets with respect to tensile index and fractography. Screened wood chips of Subabul were subjected to kraft cooking (165 °C, 3 hours) followed by ECF bleaching and refining. When unbleached handsheets were compared, higher tensile index was found for sapwood sheets (29.8 N.m/g) than heartwood sheets (12.8 N.m/g). Therefore, it is recommended to use unbleached sapwood sheets for packaging grade applications. The bleached pulps have exhibited negligible residual lignin (0.1 %), higher water retention value (∼21) and higher brightness (88 %) compared to unbleached pulps. Subsequently, the bleached heartwood sheets revealed higher tensile index (∼7 fold) and higher modulus of elasticity (∼2.7 fold) compared to unbleached heartwood sheets. For printing grade applications bleached sapwood and bleached heartwood pulps are equally recommended, because no differences were observed in their pulp and sheet characteristics.
Two Synthetic 18-Way Outcrossed Populations of Diploid Budding Yeast with Utility for Complex Trait Dissection

Published: April 2020

Abstract
Advanced-generation multiparent populations (MPPs) are a valuable tool for dissecting complex traits, having more power than genome-wide association studies to detect rare variants and higher resolution than F2 linkage mapping. To extend the advantages of MPPs in budding yeast, we describe the creation and characterization of two outbred MPPs derived from 18 genetically diverse founding strains. We carried out de novo assemblies of the genomes of the 18 founder strains, such that virtually all variation segregating between these strains is known, and represented those assemblies as Santa Cruz Genome Browser tracks. We discovered complex patterns of structural variation segregating among the founders, including a large deletion within the vacuolar ATPase VMA1, several different deletions within the osmosensor MSB2, a series of deletions and insertions at PRM7 and the adjacent BSC1, as well as copy number variation at the dehydrogenase ALD2. Resequenced haploid recombinant clones from the two MPPs have a median unrecombined block size of 66 kb, demonstrating that the population is highly recombined. We pool-sequenced the two MPPs to 3270× and 2226× coverage and demonstrated that we can accurately estimate local haplotype frequencies using pooled data. We further downsampled the pool-sequenced data to ∼20–40× and showed that local haplotype frequency estimates remained accurate, with median error rates 0.8 and 0.6% at 20× and 40×, respectively. Haplotypes frequencies are estimated much more accurately than SNP frequencies obtained directly from the same data. Deep sequencing of the two populations revealed that 10 or more founders are present at a detectable frequency for &gt; 98% of the genome, validating the utility of this resource for the exploration of the role of standing variation in the architecture of complex traits.

Abstract

The outbreak of coronavirus disease 2019 (COVID-19) has rapidly spread globally since being identified as a public health emergency of major international concern and has now been declared a pandemic by the World Health Organization (WHO). In December 2019, an outbreak of atypical pneumonia, known as COVID-19, was identified in Wuhan, China. The newly identified zoonotic coronavirus, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), is characterized by rapid human-to-human transmission. Many cancer patients frequently visit the hospital for treatment and disease surveillance. They may be immunocompromised due to the underlying malignancy or anticancer therapy and are at higher risk of developing infections. Several factors increase the risk of infection, and cancer patients commonly have multiple risk factors. Cancer patients appear to have an estimated twofold increased risk of contracting SARS-CoV-2 than the general population. With the WHO declaring the novel coronavirus outbreak a pandemic, there is an urgent need to address the impact of such a pandemic on cancer patients. This include changes to resource allocation, clinical care, and the consent process during a pandemic. Currently and due to limited data, there are no international guidelines to address the management of cancer patients in any infectious pandemic. In this review, the potential challenges associated with managing cancer patients during the COVID-19 infection pandemic will be addressed, with suggestions of some practical approaches.

Implications for Practice
The main management strategies for treating cancer patients during the COVID-19 epidemic include clear communication and education about hand hygiene, infection control measures, high-risk exposure, and the signs and symptoms of COVID-19. Consideration of risk and benefit for active intervention in the cancer population must be individualized. Postponing elective surgery or adjuvant chemotherapy for cancer patients with low risk of progression should be considered on a case-by-case basis. Minimizing outpatient visits can help to mitigate exposure and possible further transmission. Telemedicine may be used to support patients to minimize number of visits and risk of exposure. More research is needed to better understand SARS-CoV-2 virology and epidemiology.
Las finanzas conductuales y la teoría del riesgo: ¿nuevos fundamentos para la gerencia financiera?
Authors: ORTIZ BOJACÁ JOSÉ JOAQUÍN , CELIS HUGO 
Published: April 2020

Los nuevos desarrollos del conocimiento científico en el campo social han replanteado los fundamentos de la mayoría de las ciencias sociales, lo cual es relevante para las finanzas y la contabilidad, que han empezado a apoyarse en otras ciencias como la sicología, la estadística paramétrica y no paramétrica, la sociología, entre otras, de tal manera que la comprensión y la explicación de las dinámicas patrimoniales se ajusten de mejor manera a la realidad estudiada.
Específicamente en el campo de la toma de decisiones, el principio de la economía clásica de la racionalidad como fundamento para la mejor elección, se ha demostrado como insuficiente para comprender las decisiones financieras, que se apartan de dicho principio y que requieren incorporar otros elementos explicativos como son las características comportamentales, que no necesariamente son racionales, sino emocionales, afectivas, sentimentales axiológicas, entre otras. En este artículo se efectúa un análisis fundamentado de los elementos teóricos que permiten dilucidar estos nuevos enfoques, mostrando en primera instancia la problemática inmersa, ahondando mediante un análisis reflexivo a partir de desarrollos teóricos de los argumentos alrededor de estas temáticas, los constructos que conducen a mejores soluciones interpretativas y propositivas en el campo de la toma de decisiones financieras, que se traslucen en la fundamentación epistemológica de un modelo explicativo integral financiero desde el enfoque de las finanzas conductuales y bajo el paradigma de la complejidad.
