Authors: Pimentel Breno Pontes , Barbosa Andréa Teresa Riccio , Reis Marcelo de Miranda 
Published: March 2021

No Brasil, o Programa Nacional de Eficiência Energética em Edificações promove, juntamente com o INMETRO, a avaliação de eficiência energética das edificações por meio da Etiqueta Nacional de Conservação de Energia (ENCE). O regulamento que define os métodos para avaliação energética, no âmbito das edificações públicas, está sendo atualizado, passando a ser denominado Instrução Normativa INMETRO para Classe de Eficiência Energética de Edificações Comerciais, de Serviços e Públicas (INI-C). Para atender Atos Normativos do Governo Federal, os projetos de obras do Exército Brasileiro devem obter ENCE Nível 'A' e devem ser elaborados utilizando a metodologia BIM. Na INI-C, há um método que utiliza simulação termoenergética de edificações para sua classificação. O objetivo desse trabalho, portanto, é avaliar a possibilidade de fazer interoperabilidade entre o projeto elaborado em Revit e os softwares utilizados para simulação, indicando estratégias a serem seguidas nesse processo. Para isso, foi realizada uma análise energética de um pavilhão militar pelo método de simulação da INI-C, utilizando três combinações de softwares: modelagem da edificação no ScketchUp e no OpenStudio, caracterização e simulação no EnergyPlus; modelagem, caracterização e simulação da edificação no DesignBuilder; e utilização do projeto em Revit para caracterização e simulação no DesignBuilder, após processo de interoperabilidade. O consumo energético anual simulado na condição real das três modelagens foi, em média, 32.243,44 kWh com desvio máximo de 1,00% entre as modelagens. Na condição de referência, 80.118,71 kWh com desvio máximo de 0,01%. Em todas, obteve-se ENCE Geral Classe 'A', com média de 59,76% de economia energética. A modelagem que utiliza interoperabilidade entre Revit e DesignBuilder foi mais vantajosa, com economia de tempo no processo de avaliação e excelente precisão (desvio máximo de 1,00% em relação às demais). Para usufruir desse potencial, há de se seguir algumas recomendações no processo de interoperabilidade, apresentadas nesse trabalho.
Estimating the effect of transaction costs using tick-size as a proxy
Authors: Sirnes Espen 
Published: March 2021

A method is proposed for estimating the effect of transaction costs on volatility, using the tick-size as proxy. The method follows three steps: 1) collect only the cases where the tick-size changes from one regime to another, 2) estimate the effect with and without the order book size, and 3) use local data on tick-size and volatility, but instruments from international markets. The first step handles stationarity and dependence. The second step is used to infer the effect of a symmetric transaction cost as tick-size is a revenue and not a cost for liquidity providers. A regression with and without the order book may therefore indicate how much this asymmetry is likely to affect the result. The third step handles endogeneity. The method is applied on intraday data from the Norwegian Stock Exchange (OSE). The results show that both the tick-size and inferred transaction costs seems to have surprisingly little impact on volatility.

Authors: Lakra Kairovin 
Published: March 2021

Phalaris minor and Cynodon dactylon is the very problematic grassy weeds of wheat crop are responsible for significant yield reduction. Therefore, the present experiment was conducted at CSAUAT, Kanpur during Rabi season 2017-18 and 2018-19 in split-plot design with four replication having four irrigation regimes in main plot viz. irrigation at CRI and active tillering stage (I1), irrigation at CRI + jointing + booting (I2), CRI + active tillering + booting + flowering stage (I3) and irrigation at CRI + jointing + booting + flowering + milking stage (I4), and eight factors of weed management (W1-weedy check, W2-two hand weeding at 20 and 40 days after sowing (DAS), W3-sulfosulfuron 25 gha-1at 35 DAS, W4- pendimethalin (pre-em) fb WCPL-15, 400 gha-1at 35 DAS, W5- broadway (carfentrazone ethyl 20% + sulfosulfuron 25%WG) 100 gha-1at 35 DAS, W6- halauxafen + penxasulam 23.5%, 75 gha-1at 35 DAS, W7- halauxafen - methyl 1.21% w/w + fluroxypyr at 35 DAS and W8- clodinafop- propargyl 15% + metsulfuron 1%, 400 gha-135 DAS) were allocated to sub plots for assessing the effect of these treatments on grassy weeds. Irrigations at crown root initiation (CRI) and active tillering stage (I1) significantly reduce the density and weight of grassy weeds with highest WCE and crop resistance index (CRI) over other irrigation regimes. However, I4 irrigation recorded highest weed effectiveness (WE) and crop dry matter yield (CDMY) followed by I3. All the weed management options are significantly superior over weedy check. Among herbicidal treatments, lowest weed density and their weight, WE and the highest WCE, CRI, WPI and CDMY was recorded with the application of broadway (W5) followed by W8. Reducing irrigation frequency and the post emergence application of broadway are the best option for managing grassy weeds in wheat, but for higher CDMY more number of irrigations required.

Background: Placenta accrete occurs when there is abnormal attachment of the placenta to the uterine wall either partially or totally. Placenta accreta had many complications mainly intraoperative and postpartum including injury to local organs (e.g. bowel, bladder, ureters) and neurovascular structures in the retroperitoneum. The aim of the present study was to evaluate the uterine cavity after conservative management of placenta accreta by using hysteroscope.
Materials and Methods: This is prospective study was carried on 40 pregnant at Tanta University Hospital with age >35 years, to detect Presence or absence of intra uterine changes after conservative management of placenta accrete by hysteroscopy, easiness of performing diagnostic hysteroscopy and Correlation between intrauterine changes and operative data.
Results: Hysteroscopic examination of the participants showed that 30.0% with incidences of Cervical stenosis, 15.0% with uterine cavity irregularity, 15.0% with intrauterine adhesions, 10.0% with endometrial fibrosis, 5.0% with scar dehiscence and 5.0% with Remnant. There was a statistically significant positive correlation between development of cervical stenosis and endometrial thickness by US (correlation coefficient r = 0.323 with p value 0.042) .There was a statistically significant negative correlation between Endometrial fibrosis and scar thickness (correlation coefficient r = -0.538 with p value <0.001). There was a statistically significant negative correlation between Intra uterine adhesions and scar thickness (correlation coefficient r = -0.470 with p value 0.002). There was a statistically significant negative correlation between uterine cavity irregularity and duration of CS (correlation coefficient r = -0.320 with p value 0.044).
Conclusion: The frequency of abnormal hysteroscopic findings after conservative management of placenta accreta is high, for at least several months after the procedure. The most frequently found abnormalities, associated with conservative treatment, are cervical stenosis, uterine cavity irregularity and Intrauterine adhesions.

Aims: To investigate the prevalence of common mental disorders among medical students at the Federal University of Rondônia Foundation.
Study design: Cross-sectional study.
Place and Duration of Study: Department of Medicine, Federal University of Rondônia Foundation (UNIR), in October 2019.
Methodology: Cross-sectional study was conducted in October 2019, using a questionnaire adapted with the Self-Report Questionnaire 20 (SRQ-20). Sample: 116 students, 56 females and 60 males, from different periods completed the questionnaire. The prevalence of positive results in the SRQ-20 and the variance of positive responses were verified.
Results: The prevalence of positive results for the SRQ-20 was estimated at 69.8% (95% CI 61.0-78.6; 81 cases). No difference was found in the proportions of positive results for the variables analyzed (p >.05). There was no significant association between the calculated prevalence ratios and the factors analyzed (p >.05). The symptoms related to the reduction in vital energy showed the highest average amount of positive responses (76 [± 10.4]; p <.01).
Conclusion: The prevalence of positive results for the SRQ-20 observed in our study was much higher than the average reported for Brazilian medical students. The number of students who said they thought about suicide was also high. We understand that these findings reinforce the need for the development and implementation of medical students' mental health care programs to identify, monitor, and, if possible, adequately treat these cases.

Tuberculosis (TB) and human immunodeficiency virus (HIV) are major devastating infectious diseases African countries and other regions of the world. TB is a potentially serious infectious bacterial disease that mainly affects the lungs. While HIV is a virus that attacks the body's immune system; which if left untreated, can lead to acquired immunodeficiency syndrome (AIDS). Thus, this study was carried out to monitor the prevalence of tuberculosis and human immunodeficiency virus (HIV) situation in Ikere-Ekiti, Ekiti State Southwestern Nigeria. A total of 191 participants were enrolled in this study. Blood and sputum samples were used in screening of HIV and Mycobacterium tuberculosis respectively. 102(53.4%) participants were confirmed HIV positive cases and 89(46.6%) participants were confirmed as M. tuberculosis-positive cases. The rate of tuberculosis was higher among women than among men and prevalence of HIV was slightly higher among men than among female. The study shows that age group 26 – 30 years have the highest rate of tuberculosis and age group 36 – 40 years have the highest rate of HIV cases while the highest number of TB with HIV co-infection 34 (17.8%) were gotten from the age group 36 – 40years. The rate at which the prevalence of tuberculosis, HIV and their co-infection are rising is due to various challenges facing its eradication. Adequate resource mobilization and effective spending is needed to achieve success. In addition, efforts should be made to improve the surveillance system.

AbstractPurposeThe recently published AAPM TG‐275 and the public review version of TG‐315 list new recommendations for comprehensive and minimum physics initial chart checks, respectively. This article addresses the potential development and benefit of initial chart check automation when these recommendations are implemented for clinical photon/electron EBRT.MethodsEight board‐certified physicists with 2–20 years of clinical experience performed initial chart checks using checklists from TG‐275 and TG‐315. Manual check times were estimated for three types of plans (IMRT/VMAT, 3D, and 2D) and for prostate, whole pelvis, lung, breast, head and neck, and brain cancers. An expert development team of three physicists re‐evaluated the automation feasibility of TG‐275 checklist based on their experience of developing and implementing the in‐house and the commercial automation tools in our institution. Three levels of initial chart check automation were simulated: (1) Auto_UMMS_tool (which consists of in‐house program and commercially available software); (2) Auto_TG275 (with full and partial automation as indicated in TG‐275); and (3) Auto_UMMS_exp (with full and partial automation as determined by our experts’ re‐evaluation).ResultsWith no automation of initial chart checks, the ranges of manual check times were 29–56 min (full TG‐315 list) and 102–163 min (full TG‐275 list), which varied significantly with physicists but varied little at different tumor sites. The 69 of 71 checks which were considered as “not fully automated” in TG‐275 were re‐evaluated with more automation feasibility. Compared to no automation, the higher levels of automation yielded a great reduction in both manual check times (by 44%–98%) and potentially residual detectable errors (by 15–85%).ConclusionThe initial chart check automation greatly improves the practicality and efficiency of implementing the new TG recommendations. Revisiting the TG reports with new technology/practice updates may help develop and utilize more automation clinically.

AbstractObjectiveTo assess associations between head injury (HI) with loss of consciousness (LOC), ageing and markers of later‐life cerebral pathology; and to explore whether those effects may help explain subtle cognitive deficits in dementia‐free individuals.MethodsParticipants (n = 502, age = 69–71) from the 1946 British Birth Cohort underwent cognitive testing (subtests of Preclinical Alzheimer Cognitive Composite), 18F‐florbetapir Aβ‐PET and MR imaging. Measures include Aβ‐PET status, brain, hippocampal and white matter hyperintensity (WMH) volumes, normal appearing white matter (NAWM) microstructure, Alzheimer’s disease (AD)‐related cortical thickness, and serum neurofilament light chain (NFL). LOC HI metrics include HI occurring: (i) >15 years prior to the scan (ii) anytime up to age 71.ResultsCompared to those with no evidence of an LOC HI, only those reporting an LOC HI>15 years prior (16%, n = 80) performed worse on cognitive tests at age 69–71, taking into account premorbid cognition, particularly on the digit‐symbol substitution test (DSST). Smaller brain volume (BV) and adverse NAWM microstructural integrity explained 30% and 16% of the relationship between HI and DSST, respectively. We found no evidence that LOC HI was associated with Aβ load, hippocampal volume, WMH volume, AD‐related cortical thickness or NFL (all p > 0.01).InterpretationHaving a LOC HI aged 50’s and younger was linked with lower later‐life cognitive function at age ~70 than expected. This may reflect a damaging but small impact of HI; explained in part by smaller BV and different microstructure pathways but not via pathology related to AD (amyloid, hippocampal volume, AD cortical thickness) or ongoing neurodegeneration (serum NFL).

Published: March 2021

AbstractAlthough some strategies have been triggered to address the intrinsic drawbacks of zinc (Zn) anodes in aqueous Zn‐ion batteries (ZIBs), the larger issue of Zn anodes unable to cycle at a high current density with large areal capacity is neglected. Herein, the zinc phosphorus solid solution alloy (ZnP) coated on Zn foil (Zn@ZnP) prepared via a high‐efficiency electrodeposition method as a novel strategy is proposed. The phosphorus (P) atoms in the coating layer are beneficial to fast ion transfer and reducing the electrochemical activation energy during Zn stripping/plating processes. Besides, a lower energy barrier of Zn2+transferring into the coating can be attained due to the additional P. The results show that the as‐prepared Zn@ZnP anode in the symmetric cell can be cycled at a current density of 15 mA cm−2with an areal capacity of 48 mAh cm−2(depth of discharge, DOD ≈ 82%) and even at an ultrahigh current density of 20 mA cm−2and DOD ≈ 51%. Importantly, a discharge capacity of 154.4 mAh g−1in the Zn/MnO2full cell can be attained after 1000 cycles at 1 A g−1. The remarkable effect achieved by the developed strategy confirms its prospect in the large‐scale application of ZIBs for high‐power devices.

Published: March 2021

AbstractPlasmonic nanoheating can be utilized to induce nanophase transformation, which has important implications for nano‐optoelectronics, nano‐piezoelectronics, and high‐density data storage. Herein, optical poling of poly(vinyl difluoride) (PVDF) is shown with the assistance of surface plasmons. The ultrathin PVDF films are sandwiched between gold nanoparticles (Au NPs) and a gold film. By irradiating the Au NPs with continuous‐wave laser, nanoannealing of the PVDF films is realized, which locally transforms the PVDF from α phase to β phase as evidenced by Raman spectroscopy. This nanophase transformation is reproducible and scalable by scanning laser across the Au NP films deposited on the PVDF. In such a way, arbitrary patterns of β phases can be generated, which can potentially be applied for integrated piezoelectronic devices, high‐density data storage, and anti‐counterfeiting.

Multi‐Mode Water‐Tube‐Based Triboelectric Nanogenerator Designed for Low‐Frequency Energy Harvesting with Ultrahigh Volumetric Charge Density
Authors: Wu Hao , Wang Zuankai , Zi Yunlong 
Published: March 2021

AbstractVast renewable energies are contained in mechanical motions in nature such as ocean waves. However, it is challenging to effectively harness these energy sources due to their low frequency and irregularity. Triboelectric nanogenerators (TENGs) are a promising technology for renewable energy conversion, but conventional TENGs suffer from challenges including single‐mode operation, low contact intimacy, and material abrasion. Here, by encapsulating deionized DI water into a fluorinated ethylene‐propylene tube, a versatile and high‐performance water‐tube‐based TENG (WT‐TENG) is developed. Benefiting from the high flexibility of the water, the WT‐TENG can work at various operation modes and generate power from multiple mechanical energy sources. With the intimate water/solid contact, the WT‐TENG achieves an ultrahigh volumetric output charge density of 9 mC m−3 at a frequency of 0.25 Hz, beyond all previous reports. Moreover, multiple finger‐sized WT‐TENG units can be easily integrated as one device and realize multiplied outputs. A wearable body motion energy harvester and a water wave energy harvester are demonstrated as examples of the WT‐TENG applications. The proposed WT‐TENG can be regarded as a new brick for the TENG mansion, and numerous applications could be built up based on the WT‐TENG units.

AbstractVariants of the diphthamide biosynthesis I (DPH1, OMIM*603527) are associated with developmental delay, short stature, and sparse hair syndrome (DEDSSH/DPH1 syndrome) (OMIM# 616901). Another name is Loucks‐Innes syndrome. DPH1 syndrome is an ultrarare and severe neurodevelopmental disorder. Less than 20 patients were reported from different ethnicities. Here, we described the first Chinese adult with genetically confirmed DPH1 syndrome. We summarized previously reported patients in the literature and found that developmental delay, unusual skull shape, sparse hair, and facial dysmorphism were consistently present in all DPH1 syndrome patients. Dysplastic toenails and dental abnormalities are age‐dependent characteristics of DPH1 syndrome. Our patient was the first reported patient with documented growth hormone deficiency. Dental and endocrine checkup should be considered in the routine follow‐up of DPH1 syndrome patients.

AbstractMetallic nanocube ensembles exhibit tunable localized surface plasmon resonance to induce the light manipulation at the subwavelength scale. Nevertheless, precisely control anisotropic metallic nanocube ensembles with relative spatial directionality remains a challenge. Here, we report a DNA origami based nanoprinting (DOBNP) strategy to transfer the essential DNA strands with predefined sequences and positions to the surface of the gold nanocubes (AuNCs). These DNA strands ensured the specific linkages between AuNCs and gold nanoparticles (AuNPs) that generating the stereo‐controlled AuNC‐AuNP nanostructures (AANs) with controlled geometry and composition. By anchoring the single dye molecule in hot spot regions, the dramatic enhanced electromagnetic field aroused stronger surface enhanced Raman scattering (SERS) signal amplification. Our approach opens the opportunity for the fabrication of stereo‐controlled metal nanostructures for designing highly sensitive photonic devices.
