O presente trabalho objetivou analisar a estrutura horizontal e vertical do estrato arbóreo, nos fragmentos florestais com rendimento lenhoso, nas fitofisionomias nativas de floresta estacional decidual submontana presentes na faixa de domínio de um segmento da rodovia BR-116, no estado do Rio Grande do Sul. Para isso foi realizado um inventário florestal nos fragmentos florestais que ocorrem nas duas margens laterais de domínio público da rodovia, determinando-se o DAP e a altura comercial de cada árvore. Foram calculados os parâmetros fitossociológicos relacionados à estrutura horizontal e vertical das árvores contidas nessas áreas. Para analisar a diversidade do ambiente estudado, calcularam-se índices ecológicos. Cupania vernalis, Allophylus puberulus, Nectandra megapotamica, Luehea divaricata, Machaerium paraguariense e Ocotea puberula são as espécies de maior importância na estrutura horizontal nos fragmentos de floresta estacional decidual submontana que existem na faixa de domínio do trecho da rodovia BR-116, no Rio Grande do Sul. Na vegetação avaliada, ocorre maior quantidade de indivíduos no estrato médio, visto que Nectandra megapotamica, Cupania vernalis, Allophylus puberulus, Luehea divaricata, Machaerium paraguariense e Ocotea puberula apresentaram maior posição sociológica relativa, comparando-se todos os estratos. Os índices ecológicos e de qualidade mostraram valores normais para o tipo de vegetação estudada.

O objetivo do presente trabalho foi realizar a caracterização morfofisiológica de isolados de Beauveria bassiana, Cordyceps fumosorosea e Metarhizium anisopliae, em diferentes meios de cultura. Para tanto, foram utilizados quatro isolados de fungos entomopatogênicos e avaliados o crescimento micelial, a esporulação, a coloração e a caracterização dimensional dos conídios em quatro meios de cultura. O isolado de B. bassiana apresentou maior crescimento micelial e esporulação no meio V8CaCO3 ; o micélio aéreo apresentou-se de cor branca em todos os meios. O isolado de C. fumosorosea obteve maior crescimento micelial no meio de cultura completo e maior esporulação no meio batata-dextrose-ágar (BDA); o micélio aéreo variou de vermelho-claro a branco. Em relação aos isolados de M. anisopliae, o maior crescimento micelial ocorreu no meio V8CaCO3 , e as maiores produções de esporos, no meio de cultura BDA e completo; a coloração do micélio aéreo variou entre branco e tons de amarelo e verde. Os maiores valores de índice de velocidade de crescimento micelial (IVCM) foram observados quando utilizado o meio V8CaCO3 , e os menores, o meio ágar-água. Verifica-se que os meios de cultura influenciam nas características morfofisiológicas dos isolados de fungos entomopatogênicos. Considerando a viabilidade econômica, o meio de cultura BDA é o mais recomendado para a produção massal de fungos entomopatogênicos.
Lutar ou voar: registro de interações agonísticas entre sabiás (Turdus spp.) em Santa Catarina, sul do Brasil
Authors: Mario Arthur Favretto  , Osvaldo Onghero Jr.
Published: June 2022

Os sabiás são aves da família Turdidae, ocorrentes em zonas florestais, e têm como fonte alimentar principalmente frutos, complementados por sementes e invertebrados. Como pode haver muitos indivíduos dessa família em um mesmo espaço, já tinha sido registrada a ocorrência de sobreposição de nicho e de áreas de vida, implicando concorrência entre as aves desse táxon, no entanto não havia registros sobre como essas competições interespecíficas ocorriam. Neste estudo foi realizada, por meio de registros em armadilhas fotográficas, a demonstração ocasional de interações agonísticas, tais como tentativas de agressões, entre exemplares de sabiá do gênero Turdus, em disputa por recursos alimentares de origem antrópica. As investidas entre as espécies não se deram em todos os momentos em que as aves estavam próximas nem entre todas as espécies desse gênero. Fatores como tamanho do indivíduo, período reprodutivo e disponibilidade de recursos alimentares possivelmente influenciam na ocorrência ou não das agressões.
Detection of Prostate Cancer Biomarker PCA3 by Using Aptasensors
Authors: Crulhas Bruno P. , Basso Caroline R. , Castro Gustavo R. , Pedrosa Valber A.
Published: June 2022

Background:

Prostate cancer cells have very high PCA3 messenger RNA levels,
which turns them into one of the new biomarkers for prostate cancer prognosis and diagnosis.

Objective:

Our goal here is to develop a new aptasensor to detect PCA3 release by the
cancer cell.

Methods:

DNA hairpin containing PCA3 aptamer was thiolated, conjugated to methylene
blue (MB) redox probe, and immobilized on gold electrode through self-assembly to
detect label-free cancer cells.

Results:

Our data have evidenced stable and sensitive sensors presenting a wide linear detection
range (0-150ng/mL). In addition, monitoring PCA3 released by different types of
prostate cells can provide in-depth knowledge about prostate cancer dynamics; therefore,
it is a powerful platform for earlier clinical diagnostic. The released PCA3 can vary depending
on the type of adopted prostate cells.

Conclusion:

PCA3 release was monitored in a group of cells for 2 h; it showed significantly
higher expression in both LNCaP and PC-3 cells. This strategy provides a unique
and simple methodology to achieve more sensitive and specific PCA3 detection; thus, it
emerged as a promising tool for early cost-effective diagnosis
Gereinigd, klaar voor Gods komst: de doop in Lucas-Handelingen

This article provides an overview of the motif of baptism in Luke-Acts. It argues that Luke presents the baptism of John as a particular kind of Jewish purification rite, that is, as a purification that accompanies a changed way of life and that prepares the people of Israel for the coming of the Lord. In Acts, Luke emphasizes the continuity between the baptism of John and baptism in the name of Jesus. Both are baptisms of repentance and both prepare for the eschatological coming of the Lord. At the same time, differences can be seen between both baptisms: after Easter, according to Acts 18-19, the baptism of John is no longer sufficient. The conclusion links the findings to current debates on baptism in reformed churches. The practice of infant baptism has its value, but risks losing the biblical emphasis on the new way of life expected of the baptized.

Effect of dividend policy on stock price volatility of companies listed on the stock market of Vietnam
Authors:   Faculty of Banking and Finance, Thuongmai University, Hanoi, Vietnam, et al. Vu
Published: June 2022

The decision on dividend policy is considered an important decision in financial management and dividend policy is always an issue attracting the attention of investors. The purpose of this research is to identify the impact of dividend policy on the stock price volatility of companies in the stock market of Vietnam. Understanding this matter helps companies to choose an appropriate dividend policy and at the same time helps investors have an overview to make the most suitable and optimal investment decisions. The research has built a regression model to assess the impact of dividend policy on stock price volatility of companies listed on the stock market in Vietnam. The strength of this research is to use the E-view software in quantitative analysis to build a panel data regression model. At the same time, the researchers used the Hausman test to select the appropriate model compared to other research. Research data is collected using a sample size of 100 companies in all industries (except companies in the banking and finance industry) listed on two stock exchanges HOSE and HNX from 2015 to 2020. With the application of E-view software in quantitative analysis to build table data regression models, the article has built a regression model to determine the relationship and level of impact of dividend policy on the stock price volatility of companies. The research results show that the variables of dividend policy have no impact on stock price volatility, which is totally in contrast to previous studies in Vietnam.
MISG, mines and variability
Authors: Sweatman Winston , White Kevin
Published: June 2022

In 2016, a Mathematics-in-Industry Study Group (MISG) project considered the construction of mining sequences, that is, the process connecting ore extraction with specific orders. In particular, the meeting considered the potential for using knowledge about geological variability within the ore. This article revisits this MISG project and the approach developed for thinking about the problem as the build for an order progresses. We provide new perspectives on this approach and outline possible ways for further development.

Development of a WeChat-based Mobile Messaging Smoking Cessation Intervention for Chinese Immigrant Smokers: Qualitative Interview Study
Authors: Jiang Nan , Rogers Erin S , Cupertino Paula , Zhao Xiaoquan , Cartujano-Barrera Francisco , Lyu Joanne Chen , Hu Lu , Sherman Scott E
Published: June 2022

Background

Smoking remains a major public health issue among Chinese immigrants. Smoking cessation programs that focus on this population are scarce and have a limited population-level impact due to their low reach. Mobile messaging interventions have the potential to reach large audiences and expand smokers’ access to smoking cessation treatment.

Objective

This study describes the development of a culturally and linguistically appropriate mobile messaging smoking cessation intervention for Chinese immigrant smokers delivered via WeChat, the most frequently used social media platform among Chinese people globally.

Methods

This study had 2 phases. In phase 1, we developed a mobile message library based on social cognitive theory and the US Clinical Practice Guidelines for Treating Tobacco Use and Dependence. We culturally adapted messages from 2 social cognitive theory-based text messaging smoking cessation programs (SmokefreeTXT and Decídetexto). We also developed new messages targeting smokers who were not ready to quit smoking and novel content addressing Chinese immigrant smokers’ barriers to quitting and common misconceptions related to willpower and nicotine replacement therapy. In phase 2, we conducted in-depth interviews with 20 Chinese immigrant smokers (including 7 women) in New York City between July and August 2021. The interviews explored the participants’ smoking and quitting experiences followed by assessment of the text messages. Participants reviewed 17 text messages (6 educational messages, 3 self-efficacy messages, and 8 skill messages) via WeChat and rated to what extent the messages enhanced their motivation to quit, promoted confidence in quitting, and increased awareness about quitting strategies. The interviews sought feedback on poorly rated messages, explored participant preferences for content, length, and format, discussed their concerns with WeChat cessation intervention, and solicited recommendations for frequency and timing of messages.

Results

Overall, participants reported that the messages enhanced their motivation to quit, offered encouragement, and made them more informed about how to quit. Participants particularly liked the messages about the harms of smoking and strategies for quitting. They reported barriers to applying some of the quitting strategies, including coping with stress and staying abstinent at work. Participants expressed strong interest in the WeChat mobile messaging cessation intervention and commented on its potential to expand their access to smoking cessation treatment.

Conclusions

Mobile messages are well accepted by Chinese immigrant smokers. Research is needed to assess the feasibility, acceptability, and efficacy of WeChat mobile messaging smoking cessation interventions for promoting abstinence among Chinese immigrant smokers.
Error and Timeliness Analysis for Using Machine Learning to Predict Asthma Hospital Visits: Retrospective Cohort Study (Preprint)
Authors: Zhang Xiaoyi , Luo Gang
Published: June 2022

BACKGROUND

Asthma hospital visits, including emergency department visits and inpatient stays, are a significant burden on health care. To leverage preventive care more effectively in managing asthma, we previously employed machine learning and data from the University of Washington Medicine (UWM) to build the world’s most accurate model to forecast which asthma patients will have asthma hospital visits during the following 12 months.

OBJECTIVE

Currently, two questions remain regarding our model’s performance. First, for a patient who will have asthma hospital visits in the future, how far in advance can our model make an initial identification of risk? Second, if our model erroneously predicts a patient to have asthma hospital visits at the UWM during the following 12 months, how likely will the patient have ≥1 asthma hospital visit somewhere else or ≥1 surrogate indicator of a poor outcome? This work aims to answer these two questions.

METHODS

Our patient cohort included every adult asthma patient who received care at the UWM between 2011 and 2018. Using the UWM data, our model made predictions on the asthma patients in 2018. For every such patient with ≥1 asthma hospital visit at the UWM in 2019, we computed the number of days in advance that our model gave an initial warning. For every such patient erroneously predicted to have ≥1 asthma hospital visit at the UWM in 2019, we used PreManage and the UWM data to check whether the patient had ≥1 asthma hospital visit outside of the UWM in 2019 or any surrogate indicators of poor outcomes. Such surrogate indicators included a prescription for systemic corticosteroids during the following 12 months, any type of visit for asthma exacerbation during the following 12 months, and asthma hospital visits between 13 and 24 months later.

RESULTS

Among the 218 asthma patients in 2018 with asthma hospital visits at the UWM in 2019, 61.9% (135/218) were given initial warnings of such visits ≥3 months ahead by our model and 84.4% (184/218) were given initial warnings ≥1 day ahead. Among the 1310 asthma patients in 2018 who were erroneously predicted to have asthma hospital visits at the UWM in 2019, 29.01% (380/1310) had asthma hospital visits outside of the UWM in 2019 or surrogate indicators of poor outcomes.

CONCLUSIONS

Our model gave timely risk warnings for most asthma patients with poor outcomes. We found that 29.01% (380/1310) of asthma patients for whom our model gave false-positive predictions had asthma hospital visits somewhere else during the following 12 months or surrogate indicators of poor outcomes, and thus were reasonable candidates for preventive interventions. There is still significant room for improving our model to give more accurate and more timely risk warnings.

Machine Learning-Based Prediction of Atrial Fibrillation Risk Using Electronic Medical Records Among Elderly Patients (Preprint)
Authors: Kao Yung-Ta , Huang Chun-Yao , Fang Yu-Ann , Liu Ju-Chi , Chang Tzu-Hao
Published: June 2022

BACKGROUND

Atrial fibrillation (AF) is an independent risk factor that increases the risk of stroke fivefold. The purpose of our study was to develop an AF predictive model by machine learning (ML) based on 3-year medical information without electrocardiograms in our database to identify AF risk among elderly patients.

OBJECTIVE

To examine ML approaches applied to electronic medical records in our clinical research database to identify AF risk among elderly patients.

METHODS

We developed a predictive model according to the Taipei Medical University clinical research database electronic medical records, including diagnostic codes, medications, and laboratory data. Classification of new-onset AF in designated 1-year interval (retrospectively passed on judicially), judged by sensitivity, specificity, F1 score, area under the receiver operating characteristic curve (AUROC), and area under the precision-recall curve (AUPRC).

RESULTS

A total of 2138 participants (1028 female [48.1%]; mean [SD] age 78.8 [6.8] years) with AF and 8552 random controls (after the matching process) without AF (4112 female [48.1%]; mean [SD] age 78.8 [6.8] years) were included in the model. The 1-year new-onset AF risk prediction model based on the random forest algorithm using medication and diagnostic information along with specific laboratory data attained an AUROC of 0.74 and an AUPRC of 0.89, while the specificity was 98.7%. Most ML models achieved an accuracy of approximately 0.8.

CONCLUSIONS

The findings of this study suggest that our ML-based model could offer acceptable discrimination in differentiating the risk of incident AF in the following year. A targeted screening approach for AF could result in a clinical choice with efficacy for prediction of the incident AF risk in elderly patients.

The elimination of poverty as the primary goal has always been an important content that the governments of all countries pay great attention to. Over the past few decades, China has made remarkable achievements in poverty alleviation. The targets of poverty alleviation in the new era have been fulfilled as scheduled. However, it should not be ignored that with the resolution of absolute poverty in China, poverty control in the new era has become more strategic and long-term. Many problems have become the focus of poverty management in the “post-poverty era”, such as relative poor group replacing absolute poor group as the main body of poverty, preventing the group that has been lifted out of poverty from returning to poverty and preventing the occurrence of new poverty. This paper takes Chongqing southeast “national long-term governance mechanism of the border region information poverty” as the research object, focusing on poverty after the crucial information poverty on “the new absolute poverty and has Chinese out of poverty group”, the influence of the ultimate goal is to block Chinese border region phenomenon caused by poor information, strengthen poverty crucial achievement, realize common prosperity.

Abstract 1. Elephants frequently raid farmers’ crops within their ranges
in Africa and Asia. This can have a large impact on agricultural
productivity and food security for farmers. 2. Previous studies have
examined susceptibility of crop fields to elephant raids using field
characteristics such as field size and proximity to water sources.
However, there are limited studies investigating how different crop
types, individually and in their combinations influence crop
susceptibility to elephant raiding. Also, spatio-temporal patterns in
elephant crop raids in agro-ecological landscapes have not been
extensively examined. 3. This study utilised data collected from crop
fields raided by elephants between 2008 and 2018. Data on crops grown,
the number of crop-raiding incidences for each crop, and elephant
raiding incidences were recorded for each field assessed. Incidence
risks (IR) and field risk value (RV) were computed using an adaptive
epidemiological approach. 4. The results showed that elephant crop
raiding incidents varied significantly amongst crop types, and over
space and time (P<0.0001). Cereal crops (millet: Eleusine
conaracana, maize: Zea mays) incurred a higher number of crop raiding
incidents compared with leguminous crops (cowpea: Vigna unguiculata;
groundnut: Arachis hypogea). Field RVs significantly varied depending on
which crop was present in the field. There was a significant negative
correlation between the number of crop types and the susceptibility of
the field to raiding (R2 = -0.680, P<0.0001). 5. Our results
suggest that the susceptibility of the fields to elephant raids could be
minimised by selecting crop types and combinations less susceptible to
elephant damage, thus enhancing food security for local subsistence
farmers. Keywords: crop raiding, crop species, incidence risks, field
risk value, food security, human-elephant conflict
What Has Caused Regional Differences of Urban Land in China?
Authors: Cai Zhaoyang , Li Weiming , Cao Shixiong
Published: June 2022

Urbanization is a common socioeconomic development trend. However,
regional differences in urbanization, and especially in the proportion
of the total land area accounted for by urban land, threaten the
sustainable development of urbanization. To explore the causes of the
regional differences in this proportion, we obtained data from 295
cities in China, and analyzed the proportion of urban land ( PUL)
based on 11 economic dimensions using spatial econometric methods. We
found that the fiscal decentralization, infrastructure,
industrialization, and industrial upgrading were the main factors that
affected regional differences in PUL in China, with different
effects in different regions. Based on our findings, China should
continue to reform its economic institutions, give local governments
more economic autonomy, improve urbanization infrastructure, and promote
industrial upgrading by encouraging technological innovation to
stimulate more sustainable urbanization. Our results provide valuable
guidance for other countries to support more rational utilization of
urban land and achieving sustainable socioeconomic development.

Published: June 2022

Introduction/Objective. The aim of this study was to evaluate psoriasis severity and psoriatic arthritis (PsA) as metabolic syndrome (MetS) and insulin resistance (IR) predictors in patients with chronic plaque psoriasis as well as to evaluate if psoriasis severity and PsA are independent predictors for IR regardless of the MetS presence. Methods. This prospective, observational descriptive cross-sectional study was conducted at Dermatovenereological Clinic of the University Clinical Centre of Vojvodina, and included a total of 105 psoriasis patients divided into three groups: group with mild psoriasis (Psoriasis Area Severity Index ? PASI score < 10), group with moderate to severe psoriasis (PASI ?10), and group with PsA diagnosed on the basis of the CASPAR criteria. Results. Percentage of patients who had MetS was higher in the group with the severe form of psoriasis (p < 0.05) as well as IR (p = 0.05). PsA was also more frequently associated with MetS (p = 0.05) and IR (p < 0.01). In patients without MetS, no association between psoriasis severity and IR was found (p = 1.0), although there was a positive correlation between PASI and index of ?-cells secretory capacity % (HOMA B), which shows tendency for IR development. The association between PsA and presence of IR in patients without MetS was statistically significant (p < 0.05). Conclusion. MetS and IR prevalence increases in patients with PsA and in patients with the moderate and severe form of chronic plaque psoriasis. Both psoriasis severity and PsA are independent predictors for IR regardless of the MetS presence.

Published: June 2022

OBJECTIVE

Administration of supplemental sliding scale insulin for correction of hyperglycemia in non–intensive care unit (ICU) patients with type 2 diabetes is frequently used with basal-bolus insulin regimens. In this noninferiority randomized controlled trial we tested whether glycemic control is similar with and without aggressive sliding scale insulin treatment before meals and bedtime in patients treated with basal-bolus insulin regimens.

RESEARCH DESIGN AND METHODS

Patients with type 2 diabetes with admission blood glucose (BG) 140–400 mg/dL treated with basal-bolus insulin were randomized to intensive (correction for BG >140 mg/dL, n = 108) or to nonintensive (correction for BG >260 mg/dL, n = 107) administration of rapid-acting sliding scale insulin before meals and bedtime. The groups received the same amount of sliding scale insulin for BG >260 mg/dL. Primary outcome was difference in mean daily BG levels between the groups during hospitalization.

RESULTS

Mean daily BG in the nonintensive group was noninferior to BG in the intensive group with equivalence margin of 18 mg/dL (intensive 172 ± 38 mg/dL vs. nonintensive 173 ± 43 mg/dL, P = 0.001 for noninferiority). There were no differences in the proportion of target BG readings of 70–180 mg/dL, <70 or <54 mg/dL (hypoglycemia), or >350 mg/dL (severe hyperglycemia) or total, basal, or prandial insulin doses. Significantly fewer subjects received sliding scale insulin in the nonintensive (n = 36 [34%]) compared with the intensive (n = 98 [91%] [P < 0.0001]) group with no differences in sliding scale insulin doses between the groups among those who received sliding scale insulin (intensive 7 ± 4 units/day vs. nonintensive 8 ± 4 units/day, P = 0.34).

CONCLUSIONS

Among non-ICU patients with type 2 diabetes on optimal basal-bolus insulin regimen with moderate hyperglycemia (BG <260 mg/dL), a less intensive sliding scale insulin treatment did not significantly affect glycemic control.

Susut energi adalah energi yang tidak tersalurkan dari gardu induk kepada konsumen dan menyebabkan kerugian penjualan bagi PT. PLN (persero). Salah satu penyebab kerugian ini adalah anomali pemakaian energi terutama pada pelanggan prioritas dengan daya 16.500 VA keatas, sehingga jumlah yang dibayar pelanggan dengan energi yang digunakan tidak seimbang. Oleh sebab itu dilakukan upaya penurunan susut non teknis tersebut mengunakan sistem AMR (Automatic Meter Reading). Ketidaknormalan pengukuran energi pada pelanggan prioritas dengan sistem AMR dapat dilihat dari diagram fasornya yang menunjukan tegangan phasa S tidak terukur dan bernilai 0 yang disebabkan oleh error pada sistem pengukuran tegangan kWh meternya, sehingga dilakukan pengantian kWh untuk menghindari kerugian yang tidak tercatat oleh sistem AMR. Selain itu juga dapat diketahui dengan menganalisa tagihan rekening listrik yang menurun setiap bulannya. Dari penelitian yang telah penulis lakukan, terdapat 1 pelanggan prioritas dengan daya 16.500 VA yang mengalami kelainan dalam pengunaan energi listrik yang disebabkan oleh kerusakan kWh sehingga tidak dapat mengukur arus. Pelanggan yang mengalami hal ini adalah pelanggan dengan ID Pel 132541280395. Tagihan susulan yang didapat adalah sebesar 811.669 kWh atau dirupiahkan sebesar Rp. 11.909.456.

Daya output panel surya ditentukan oleh temperatur dan radiasi cahaya matahari yang mengenai panel surya tersebut. Daya panel surya memiliki satu titik maksimum pada setiap perubahan temperatur dan radiasi cahaya matahari. Daya output maksimum ini dapat diperoleh dengan cara mengatur tegangan output panel surya pada titik daya maksimum, yang disebut juga dengan Maximum Power Point Tracking (MPPT). Penelitian ini mengusulkan sistem MPPT pada panel surya dengan menggunakan konverter boost. Pengaturan tegangan output panel surya dilakukan dengan menggunakan algoritma MPPT berbasis Fuzzy Logic Controller (FLC). Algoritma FLC ini dikembangkan dari algoritma Perturbasi dan Observasi (PO).Sistem kendali MPPT berbasis FLC ini diimplementasikan pada empat buah panel surya 50 WP dengan menggunakan Arduino Mega 2560 sebagai peralatan kontrolnya. Hasil pengujian menunjukan bahwa system kendali MPPT berbasis FLC yang diusulkan telah bekerja dengan baik, dimana alat ini telah mampu mengendalikan daya output panel surya tetap berada pada titik maksimum setiap saat.

ULP Lubuk Sikaping has two main sources to supply its working area, namely from the Padang Luar Substation (GI) and GI Simpang Empat. Along with the increasing use of electricity in its working area, the main problem faced by the ULP Lubuk Sikaping at this time is the voltage drop at the Rao Substation (GH) which is the farthest GH in the ULP Lubuk Sikaping working area. Due to the increase in the use of electricity while there is no addition to the source, GH Rao as the most remote area will experience the largest voltage drop. Moreover, when there is a disturbance in one of the main sources, at the Peak Load Time (WPB) ULP Lubuk Sikaping experiences a very large voltage drop and must release a load of 90 Ampere. This greatly affects the sale of electrical energy at ULP Lubuk Sikaping. There are several ways to overcome this problem, the first is the construction of a substation at ULP Lubuk Sikaping, but because the construction of a substation requires a large amount of money and takes a long time, the right step to be taken is the interconnection of Rao-Kota Nopan (ROPAN).
