Authors: Viana Blandina Felipe , Melo Amada Mariana Costa de , Drumond Patricia Dias
Published: May 2022

Determinar as características do habitat que explicam a variação da composição dos polinizadores é importante para compreender como a alteração do habitat pode afetar a dinâmica de suas populações. Neste estudo, os padrões da composição de abelhas e vespas solitárias foram relacionados aos fatores ambientais em fragmentos urbanos em Salvador, Bahia (13º01’ S e 38º31’ W), Brasil. O estudo foi realizado de novembro de 2001 a janeiro de 2003. As abelhas e vespas foram amostradas em 14 pontos selecionados e distribuídos ao longo de dois fragmentos. Variáveis ambientais referentes à estrutura do habitat foram mensuradas em cada ponto. A análise Canônica de Correspondência (CCA) foi realizada para determinar quais fatores estariam afetando a composição de abelhas e vespas. A colonização dos ninhos armadilha por abelhas e vespas foi significativamente influenciada pelas características do microhabitat, como cobertura do dossel da floresta, densidade do sub-bosque e exposição ao sol. Entretanto, a composição de Euglossina não variou significativamente ao longo do gradiente de qualidade do habitat. Os resultados mostraram uma tendência de redução da riqueza e abundância em pontos amostrais altamente perturbados. Sugere-se a necessidade de experimentos sobre os requerimentos de habitat para prever os efeitos da alteração do habitat sobre as populações de polinizadores.

No extremo sul do Estado da Bahia, a Mata Atlântica tem sido fortemente afetada pelas atividades humanas. As formigas são vistas como indicadores biológicos confiáveis por serem sensíveis às mudanças das condições do ambiente, permitindo uma avaliação do impacto ambiental. O objetivo do presente estudo foi de avaliar a qualidade ambiental em quatro remanescentes de Mata Atlântica através de uma análise da estrutura das assembléias de Formicidae. As quatro reservas estudadas, todas situadas naquela região, foram: reserva da escola agrícola EMARC, Município de Teixeira de Freitas; Fazenda Vista Alegre, Alcobaça; Fazenda FIBRASA, Itamarajú e Fazenda Riacho das Pedras, Prado. Em cada área, foram amostrados 50 pontos de um metro quadrado de serapilheira, com o auxílio de armadilhas de tipo “Winkler”. O maior número de espécies observado foi na Fazenda FIBRASA (55 espécies) e na Fazenda Riacho das Pedras, seguidas pela Fazenda Vista Alegre (33) e a reserva da EMARC (22). A área de maior diversidade de espécies esperada (estimador Chao2) é também a da Fazenda FIBRASA, enquanto a área da EMARC foi também a de menor diversidade esperada. As espécies mais freqüentes na reserva da EMARC foram Wasmannia auropunctata (60% das amostras) e Solenopsis sp1 (58%); na Fazenda FIBRASA, W. auropunctata (64%) e Solenopsis sp.1 (46%); na Fazenda Riacho das Pedras, Pyramica eggersi (80%) e Solenopsis sp.1 (64%); na Fazenda Vista Alegre, Pheidole sp.1 (34%), Hypoponera sp.8 (32%) e Pyramica denticulata (24%). Existem correlações entre o nível de impacto humano e as riquezas específica e genérica, assim como com outras variáveis ecológicas, nas áreas estudadas. Todas essas apresentaram uma ocorrência elevada de espécies típicas de ambientes degradados, como é o caso de W. auropunctata, mostrando a urgência que existe numa política de conservação mais efetiva dos cada vez mais raros remanescentes do extremo sul do Estado da Bahia.
Focus quality in raster-scan imaging via a multimode fiber
Authors: Lyu Zhouping , Osnabrugge Gerwin , Pinkse Pepijn W. H. , Amitonova Lyubov V.
Published: May 2022

A multimode fiber (MMF) is a minimally invasive imaging probe. The most
popular approach of MMF-based microscopy is raster-scan imaging, where
the sample is illuminated by foci optimized on the fiber output facet
by wavefront shaping (WFS). Imaging quality can be quantified by
characteristic parameters of the optimized spots. We investigate the
influence of the input light position on WFS through a round-core MMF
with partial mode control, a situation often encountered in real life.
We further demonstrate a trade-off between the shape and contrast of
the foci generated on the output facet: the center input position is
beneficial for high-contrast imaging, while the edge input position
helps to reduce focus aberrations. These results are important for
high field-of-view raster-scan imaging via an MMF.
High-speed imaging of spatiotemporal correlations in Hong-Ou-Mandel interference

Published: May 2022

The Hong-Ou-Mandel interference effect lies at the heart of many emerging quantum technologies whose performance can be significantly enhanced with increasing numbers of entangled modes one could measure and thus utilize. Photon pairs generated through the process of spontaneous parametric down conversion are known to be entangled in a vast number of modes in the various degrees of freedom (DOF) the photons possess such as time, energy, and momentum, etc. Due to limitations in detection technology and techniques, often only one such DOFs can be effectively measured at a time, resulting in much lost potential. Here, we experimentally demonstrate, with the aid of a time tagging camera, high speed measurement and characterization of two-photon interference. With a data acquisition time of only a few seconds, we observe a bi-photon interference and coalescence visibility of ∼64% with potentially up to ∼2 × 103 spatial modes. These results open up a route for practical applications of using the high dimensionality of spatiotemporal DOF in two-photon interference, and in particular, for quantum sensing and communication.
Closed-form model and analysis for the enhancement effect of a rectangular plate in the scattering characteristics of multiphoton quantum radar
Authors: Tian Zhifu , Wu Di , Xu Yan , Zhou Xiaopeng , Zhang Yuqiao , Hu Tao
Published: May 2022

A closed-form model of multiphoton quantum radar cross-section (QRCS) in the monostatic scenes is constructed for rectangular flat plates based on quantum interference and uncertainty. The model is justified by the comprehensive analysis of the model parameters in the model building process. Then, we use the model to quantitatively analyze the main lobe enhancement effect of multiphoton QRCS, which means that the more incident photons will enhance the main lobe magnitude of QRCS with other factors being the same. Moreover, we predict that enhancement effects might also exist for the side lobe close to the main lobe. In addition, we present the specific conditions for side lobe enhancement. On this basis, the enhancement angle range is defined to unify the description of the main lobe and side lobe enhancement effects. The influencing factors of the enhancement angle range are clarified. The results exhibit that the angle range of enhancement in multiphoton QRCS fluctuates with the change of target size and incident wavelength. All enhancement effects are exponentially related to the incident photon number. This work brings the description of multiphoton QRCS into the closed-form model analysis stage, which will provide prior information for research in many fields, such as photonic technology, radar technology, and precision metrology.
Quantized spiral-phase-modulation based deep learning for real-time defocusing distance prediction
Authors: Zhang Zezheng , Chan Ryan K. Y. , Wong Kenneth K. Y.
Published: May 2022

Whole slide imaging (WSI) has become an essential tool in pathological diagnosis, owing to its convenience on remote and collaborative review. However, how to bring the sample at the optimal position in the axial direction and image without defocusing artefacts is still a challenge, as traditional methods are either not universal or time-consuming. Until recently, deep learning has been shown to be effective in the autofocusing task in predicting defocusing distance. Here, we apply quantized spiral phase modulation on the Fourier domain of the captured images before feeding them into a light-weight neural network. It can significantly reduce the average predicting error to be lower than any previous work on an open dataset. Also, the high predicting speed strongly supports it can be applied on an edge device for real-time tasks with limited computational source and memory footprint.

Published: May 2022

We demonstrate second-harmonic generation (SHG) microscopy excited by
the ∼890-nm light frequency-doubled from a 137-fs, 19.4-MHz, and
300-mW all-fiber mode-locked laser centered at 1780 nm. The
mode-locking at the 1.7-µm window is realized by controlling the
emission peak of the gain fiber, and uses the dispersion management
technique to broaden the optical spectrum up to 30 nm. The spectrum is
maintained during the amplification and the pulse is compressed by
single-mode fibers. The SHG imaging performance is showcased on a
mouse skull, leg, and tail. Two-photon fluorescence imaging is also
demonstrated on C. elegans labeled with
green and red fluorescent proteins. The frequency-doubled all-fiber
laser system provides a compact and efficient tool for SHG and
fluorescence microscopy.

Published: May 2022

Microresonator soliton frequency combs offer unique flexibility in synthesizing microwaves over a wide range of frequencies, while their phase noise is currently limited by thermal noise. Enlarging the mode volume would mitigate thermal noise but also raise power consumption. Here, we fabricate optical microresonators with large mode volumes by lathe machining high-purity fiber preforms. Quality factors greater than 4 billion result in a record-low threshold power of 110 µW to initiate comb operation in millimeter-sized devices. The synthesized X-band microwaves with an absolute phase noise level of

Fast transient events, such as the disintegration of liquid bodies or chemical reactions between radical species, involve various processes that may occur at different time scales. Currently, there are two alternatives for monitoring such events: burst- or high-speed imaging. Burst imaging at ultrahigh speeds (

high-speed imaging technology. However, the use of such systems eliminates the possibility to observe dynamics occurring on the sub-microsecond time scale. In this paper, we present a solution to this technological gap by combining multiplexed imaging with high-speed sensor technology, resulting in temporally resolved, high-spatial-resolution image series at two simultaneous time scales. We further demonstrate how the collection of such data opens up the tracking of rapidly evolving structures up to MHz burst rates over long durations, allowing, for the first time, to our knowledge, the extraction of acceleration fields acting upon the liquid bodies of an atomizing spray in two dimensions at kHz frame rates.

Identifying structural differences among proteins can be a non-trivial task. When contrasting ensembles of protein structures obtained from molecular dynamics simulations, biologically-relevant features can be easily overshadowed by spurious fluctuations. Here, we present SINATRA Pro, a computational pipeline designed to robustly identify topological differences between two sets of protein structures. Algorithmically, SINATRA Pro works by first taking in the 3D atomic coordinates for each protein snapshot and summarizing them according to their underlying topology. Statistically significant topological features are then projected back onto a user-selected representative protein structure, thus facilitating the visual identification of biophysical signatures of different protein ensembles. We assess the ability of SINATRA Pro to detect minute conformational changes in five independent protein systems of varying complexities. In all test cases, SINATRA Pro identifies known structural features that have been validated by previous experimental and computational studies, as well as novel features that are also likely to be biologically-relevant according to the literature. These results highlight SINATRA Pro as a promising method for facilitating the non-trivial task of pattern recognition in trajectories resulting from molecular dynamics simulations, with substantially increased resolution.

Published: May 2022

Health systems in many low- and middle-income countries are struggling to manage type 2 diabetes (T2D). Management of glycaemia via well-organized care can reduce T2D incidence, and associated morbidity and mortality. The primary aim of this study was to evaluate the effectiveness of facility plus community care interventions (integrated care), compared to facility only care interventions (facility care) towards improvement of T2D outcomes in Uganda and South Africa. A pragmatic cluster randomized trial design was used to compare outcomes among participants with T2D and those at high risk. The trial had two study arms; the integrated care arm, and the facility care arm; and in Uganda only, an additional usual care arm. Participants were enrolled at nine primary health facilities in Uganda, and two in South Africa. Participants were adults aged 30 to 75 years, and followed for up to 12 months. Primary outcomes were glycaemic control among participants with T2D, and reduction in HbA1c > = 3 mmol/mol among participants at high risk. Secondary outcomes were retention into care and incident T2D. Adjusted analysis revealed significantly higher retention into care comparing integrated care and facility care versus usual care in Uganda and integrated care versus facility care in South Africa. The effect was particularly high among participants at high risk in Uganda with an incident rate ratio of 2.46 [1.33–4.53] for the facility care arm and 3.52 [2.13–5.80] for the integrated care arm. No improvement in glycaemic control or reduction in HbA1c was found in either country. However, considerable and unbalanced loss to follow-up compromised assessment of the intervention effect on HbA1c. Study interventions significantly improved retention into care, especially compared to usual care in Uganda. This highlights the need for adequate primary care for T2D and suggest a role for the community in T2D prevention.

Authors: Queiroz-Glauss Camila P. , Vieira Mariana S. , Gonçalves-Pereira Marcela Helena , Almeida Stephanie S. , Freire Rachel H. , Gomes Maria A. , Alvarez-Leite Jacqueline I. , Santiago Helton C.
Published: May 2022

Background

Epidemiological and experimental studies have shown a protective effect of helminth infections in weight gain and against the development of metabolic dysfunctions in the host. However, the mechanisms Treg cells exert in the helminth-obesity interface has been poorly investigated. The present study aimed to verify the influence ofHeligmosomoides polygyrusinfection in early stages of high fat diet-induced obesity.

Principal findings

The presence of infection was able to prevent exacerbated weight gain in mice fed with high fat diet when compared to non-infected controls. In addition, infected animals displayed improved insulin sensitivity and decreased fat accumulation in the liver. Obesity-associated inflammation was reduced in the presence of infection, demonstrated by lower levels of leptin and resistin, lower infiltration of Th1 and Th17 cells in adipose tissue, higher expression of IL10 and adiponectin, increased infiltration of Th2 and eosinophils in adipose tissue of infected animals. Of note, the parasite infection was associated with increased Treg frequency in adipose tissue which showed higher expression of cell surface markers of function and activation, like LAP and CD134. The infection could also increase adipose Treg suppressor function in animals on high fat diet.

Conclusion

These data suggest thatH.polygyrusmodulates adipose tissue Treg cells with implication for weight gain and metabolic syndrome.

Introduction

REsilience and Activities for every DaY (READY) is an Acceptance and Commitment Therapy-based group resilience-training program that has preliminary empirical support in promoting quality of life and other psychosocial outcomes in people with multiple sclerosis (PwMS). Consistent with the Medical Research Council framework for developing and evaluating complex interventions, we conducted a pilot randomized controlled trial (RCT), followed by a phase III RCT. The present paper describes the phase III RCT protocol.

Methods and analysis

This is a multi-centre cluster RCT comparing READY with a group relaxation program (1:1 ratio) in 240 PwMS from eight centres in Italy (trial registration: isrctn.org Identifier: ISRCTN67194859). Both interventions are composed of 7 weekly sessions plus a booster session five weeks later. Resilience (primary outcome), mood, health-related quality of life, well-being and psychological flexibility will be assessed at baseline, after the booster session, and at three and six month follow-ups. If face-to-face group meetings are interrupted because of COVID-19 related-issues, participants will be invited to complete their intervention via teleconferencing. Relevant COVID-19 information will be collected and the COVID-19 Peritraumatic Distress scale will be administered (ancillary study) at baseline and 3-month follow-up. Analysis will be by intention-to-treat to show superiority of READY over relaxation. Longitudinal changes will be compared between the two arms using repeated-measures, hierarchical generalized linear mixed models.

Conclusion

It is expected that his study will contribute to the body of evidence on the efficacy and effectiveness of READY by comparing it with an active group intervention in frontline MS rehabilitation and clinical settings. Results will be disseminated in peer-reviewed journals and at other relevant conferences.

The objective of this study was to investigate the nutritional quality of bovine colostrum and whey mixtures. Five whey with bovine colostrum formulations were prepared (90:10; 80:20; 70:30; 60:40 and 50:50 whey:colostrum v:v) to be subjected to low-temperature pasteurization (63°C to 65°C for 30 minutes) and freeze-drying. The samples underwent chemical composition characterization, fatty acid profile analysis, determination of contamination by Enterobacteriaceae, pH, and Dornic acidity measurements before and after vat pasteurization. The amount of protein, fat, total solids, defatted dry extract, Brix and density increased as the bovine colostrum concentration increased. The level of saturated fatty acids and the thrombogenicity and atherogenicity indices reduced, while unsaturated fatty acids increased as the level of added bovine colostrum increased. The low-temperature pasteurization of the formulations was possible and effective, eliminating contamination by Enterobacteriaceae in the samples. Mixing bovine colostrum and whey reduced the colostrum viscosity, allowing a successful pasteurization procedure. Due to colostrum composition, the formulations yielded a higher nutritional value when compared to whey alone. The parameters applied in the formulation of mixtures of bovine colostrum and whey resulted in valuable ingredients for preparing novel dairy products.
Continued versus discontinued oxytocin after the active phase of labor: An updated systematic review and meta-analysis
Authors: Jiang Danni , Yang Yang , Zhang Xinxin , Nie Xiaocui
Published: May 2022

Objective

To systematically assess the effect of discontinued vs continued oxytocin after active stage of labour is established.

Methods

Pubmed, Embase, and the Cochrane Library were systematically searched to 18 April 2021. The risk ratio or mean difference with corresponding 95% confidence interval were computed to investigate the effect of intervention or control on maternal and fetus outcomes. This review was registered in the International Prospective Register of Systematic Reviews: CRD42021249635.

Results

Discontinuing oxytocin when the active labour was established might decrease the risk of cesarean delivery [RR (95% CI): 0.84 (0.72–0.98), P = 0.02]. However, when we restricted our analysis to women who performed cesarean section after the active phase was reached, the difference was no longer significant [RR (95% CI): 0.82 (0.60–1.10), P = 0.19]. The incidence of uterine tachysystole [RR (95% CI): 0.36 (0.27–0.49)], postpartum hemorrhage [RR (95% CI): 0.78 (0.65–0.93)], and non-reassuring fetal heart rate [RR (95% CI): 0.66 (0.58–0.76)] were significantly lower in the oxytocin discontinuation group. We also found a possible decrease in the risk of chorioamnionitis in discontinued oxytocin group [RR (95% CI): 2.77 (1.02–5.08)]. An increased duration of active [MD (95% CI): 2.28 (2.86–41.71)] and second [MD (95% CI): 5.36 (3.18–7.54)] phase of labour was observed in discontinued oxytocin group, while the total delivery time was not significantly different [MD (95% CI): 20.17 (-24.92–65.26)].

Conclusion

After the active labor is reached, discontinuation of oxytocin could be considered a new recommendation for the improved maternal and fetal outcomes without delaying labour.
Ikeafication: The Bridge and the rise of Nordic noir
Authors: Hill Stephen
Published: May 2022

This article explores how international audiences identify with Nordic noir, and The Bridge in particular, as a way of mediating complex identity discourses and the economics of social welfare. It will be suggested that, while the influence of Scandinavian culture on the United Kingdom can be framed as an idealistic touristic projection, the appeal of Nordic noir is more complicated. On the surface, it may seem to embody positional cultural consumption and middle-class privilege; however, it is also a barometer of anxiety about dark undercurrents in UK politics at a time of change and uncertainty. At the beginning of the time of writing (2020), Britain had yet to negotiate its future relationship with the European Union following the result of the 2016 Referendum: the intervening four years having seen a rise of right-wing populism in the United Kingdom and polarization over Brexit. Overshadowing this had been the presidency of Donald Trump in the United States and an ongoing migrant crisis emanating from the war in Syria. As one respondent, invoking Shakespeare’s Hamlet, stated: ‘There’s something rotten in the state of…’. Building on the work of Creeber, Robbins Nielsen, Waade, and Alexi, it will be argued that, far from being a unique dreamland, The Bridge is a symbol of both Diaspora (Bhaba) and postmodernity (Baudrillard), and that the popularity of Scandinavian noir with international audiences is concomitant to an awareness that their own worlds are less singular.

El Club Deportivo Logroño durante la Segunda República
Authors: Mota Zurdo David , Zúñiga Crespo Javier
Published: May 2022

La historia del Deportivo Logroño durante la II República estuvo marcada por la irregularidad a todos los niveles de la entidad; en lo económico, en lo deportivo y en las relaciones federativas. Este artículo analiza de manera pormenorizada la trayectoria del club desde 1930 hasta ya iniciada la Guerra Civil, valiéndose de un estudio exhaustivo de las fuentes hemerográficas y, en segunda instancia, bibliográficas. Asentado ya a comienzo de los años treinta como club insignia del territorio riojano, le tocó bregar con el cada vez más exigente esfuerzo económico que requería la profesionalización del fútbol, así como con su condición de club «foráneo» en la Federación Guipuzcoana. A nivel deportivo consiguió hazañas como una meritoria semifinal de la Copa de España o la consecución del título de campeón del Torneo Mancomunado. La mayor parte del tiempo compitieron en la Tercera División de Liga, con un fugaz paso por la Segunda División en la temporada 1934-1935. Durante este tiempo el club tuvo que enfrentarse a decisiones arbitrarias de los organismos federativos o bien resoluciones de las que casi siempre salía perjudicado al no saber imponerse en las esferas de poder del fútbol español. Por último, se estudia la crisis económica y deportiva que termina con la desaparición efectiva del club en 1935, si bien nunca se disolvió de manera oficial como se demuestra en el artículo.
HIGH AIR-VOID VOLUME IMPLICATIONS FOR ASPHALT CONCRETE SERVICE-LIFE AND PRICE PENALTY
Authors: Salini Reus , Lenngren Carl Anders
Published: May 2022

In road industry, the construction of asphalt concrete layers is a dynamic process that, if not properly done, will lead to problems compromising the pavement performance. One of the most common problems is poor compaction leading to air-void volume above the maximum acceptable. This study discusses the impact of compaction/density deficiencies and presents an innovative model to calculate the asphalt pavement service-life loss in a simple and objective way, and in line with the road construction managers needs to calculate price penalty for contractors. The model was optimized for dense graded asphalt concrete, that typically has a maximum acceptable air‑void volume between 4% and 7%.

Published: May 2022

Pumpkin seed is one of the abundant and nutrient-rich local foods. However, their use is limited. Thus, research is needed to develop it. This study aims to determine the flavonoid content and assess the acute toxicity of pumpkin seed powder in male Wistar rats. This type of research was pure laboratory experimental research. The research sample used eight-week-old male Wistar rats taken by Simple Random Sampling with 20 Wistar rats divided into four groups: one control group and three treatment groups (given 17.000, 20.000, 22.500 mg/kg BW of pumpkin seed powder). The content of flavonoid compounds was analyzed using the microchemical method, the total flavonoid content was analyzed using a UV-Visible spectrophotometer, the LD50 value was analyzed using probit analysis on SPSS, and changes in body weight of the experimental animals were analyzed using the Paired T-Test and One-Way Anova test.

Published: May 2022

Blockchain technology has subverted traditional supply chain operational models and transformed information interactions along supply chains. This paper examines the impact of blockchain technology on supply chain information collaboration and operating costs. This paper develops a three-level supply chain model based on blockchain technology that incorporates retailer sensitivity to information. First, the manufacturer’s profit function is developed, and the optimal information-sharing quantity and supply chain pricing decisions are analysed. Then, cost models for both the traditional supply chain and the novel supply chain using blockchain technology are developed and the impact of blockchain technology on supply chain operating costs is determined. The results demonstrate that blockchain technology can effectively reduce supply chain operating costs. In addition, this study has an interesting finding that if blockchain adoption is valuable for the supply chain, the quantity of information-sensitive should be moderate. Too many or too few information-sensitive retailers can reduce the value of the blockchain's use. This is because blockchain is implementation will increase the privacy concerns of supply chain companies.

Three types of gold nanoparticles (AuNPs) were synthesised with a custom-made Ultrasonic Spray Pyrolysis (USP) device, from aqueous solutions of gold (III) chloride (AuCl3) and gold (III) acetate (AuC6H12O6), with an initial concentration of Au 0.5 g/L. AuNPs were collected in suspensions of deionised (D.I.) water with the stabilisers polyvinylpyrrolidone (PVP) or polyethylene glycol (PEG), followed by the process of freeze drying the AuNPs to be useful as a new additive for the cream. The standard cream base was used as a matrix for preparation of three types of cream with AuNPs in the same concentration ratios. The third AuNPs cream was prepared with a patented hydroxylated fullerene water complex (3HFWC-W) matrix. To examine the effect of AuNPs as additive in creams, a six-week study of test creams was conducted on 33 volunteers with no dermatological diseases. During the study three main parameters of the skin where measured: Collagen quality, skin moisturisation and the epidermis-dermis function. The results of the study found improvements of collagen quality between 18-24 %, achieved due to the use of AuNPs in standard creams, while the cream with the combination of 3HFWC-W and AuNPs gave significantly higher improvements with a value of 45.7 %. It was also discovered that hydration of the skin (stratum cornum) increased by 6.4-9.6 % in standard creams with AuNPs, and 73.7 % in the 3HFWC/AuNPs` cream. Similar results were measured by the epidermis-dermis function, where 24-28 % improvement for standard creams with AuNPs was identified, and 38.4 % for the cream 3HFWC-W/AuNPs.
Physiological response of endurance exercise as a growth hormone mediator in adolescent women’s
Authors: Sugiharto  , Merawati Desiana , Pranoto Adi , Susanto Hendra
Published: May 2022

Objectives

Overweight status decreases the growth hormone (GH) secretion, thus, increasing the risk factors for medical complications. However, proper exercise is reported to enhance GH and affect the energy balance. Therefore, exercise is proclaimed to be an accurate and engaging therapy to increase GH in preventing overweight. This study aims to investigate the physiological response of exercise in mediating the increase of GH secretion in female adolescents.

Methods

22 overweight women aged 19–20 years old, with maximal oxygen consumption of 27–35 mL/kg/min, were selected as sample size. They were divided into three groups, namely (CONT, n=7) Control, (MIEE, n=7) Moderate-intensity interval endurance exercise, and (MCEE, n=8) Moderate-intensity continuous endurance exercise. The exercise was carried out by running for 30–35 min using treadmills with an intensity of 60–70% HRmax. The blood sampling for GH examination was carried out four times before exercise, 10 min, 6 h, and 24 h after exercise. The enzyme-linked immunosorbent assay (ELISA) was used to measure the GH and IGF-1 levels. The data analysis was carried out using a one-way ANOVA test, with a significance level of 5%.

Results

The results of the one-Way ANOVA test suggested a significantly different average GH and IGF-1 before and after the exercise between the three groups (CON, MIEE, and MCEE) (p≤0.05).

Conclusions

MCEE increases the GH and IGF-1 levels more considerably than MIEE. Therefore, exercise is a mediator to increase GH and IGF-1 secretion in overweight individuals. Exercise could be a viable therapy for overweight people.
Managing Capital Flows: Theoretical Advances and IMF Policy Frameworks
Authors: Korinek Anton
Published: May 2022

We analyze recent theoretical advances in the area of capital flow management and compare them with the IMF’s policy frameworks in the area, as laid out in the IMF’s Institutional View and related documents. Although the Institutional View represented an important leap forward, we discuss several tensions with the academic literature. We also emphasize the important role that the IMF guidance could play in building a better set of policy instruments to deal with volatile capital flows. More broadly, individual countries need sufficient policy space to pursue their individual welfare objectives. Finally, we propose how to strengthen the IMF’s analytical framework for international spillovers.
Design of thin-film configuration of SnO2–Ag2O composites for NO2 gas-sensing applications
Authors: Liang Yuan-Chang , Hsu Yu-Wei
Published: May 2022

In this study, a two-layered thin-film structure consisting of a dispersed nanoscaled Ag2O phase and SnO2 layer (SA) and a mono-composite film layer (CSA) consisting of a nanoscale Ag2O phase in the SnO2 matrix are designed and fabricated for NO2 gas sensor applications. Two-layered and mono-layered SnO2–Ag2O composite thin films were synthesized using two-step SnO2 and Ag2O sputtering processes and Ag2O/SnO2 co-sputtering approach, respectively. In NO2 gas-sensing measurement results, both SA and CSA thin films that functionalized with an appropriate Ag2O content exhibit enhanced gas-sensing responses toward low-concentration NO2 gas in comparison with that of pristine SnO2 thin film. In particular, a gas sensor made from the mono-composite SnO2–Ag2O layer demonstrates apparently higher NO2 gas-sensing performance than that of double-layered SnO2–Ag2O thin-film sensor. This is attributed to substantially numerous p–n junctions of Ag2O/SnO2 formed in the top region of the SnO2 matrix. The gas-sensing response of the optimal sample (CSA270) toward 10 ppm NO2 gas is 5.91, and the response/recovery speeds in a single cycle dynamic response plot are 28 s/168 s toward 10 ppm NO2, respectively. Such a p–n thin-film configuration is beneficial to induce large electric resistance variation before and after the introduction of NO2 target gas during gas-sensing tests. The experimental results herein demonstrate that the gas-sensing performance of p–n oxide composite thin films can be tuned via the appropriate design of composite thin-film configuration.
Calibrated Energy Modeling Importance—A Sensitivity Analysis of Building Enclosure Performance Factors
Authors: Civitillo John M. , Civitillo Victoria T.
Published: May 2022

The green building movement has motivated many governing bodies to pursue regulation of building energy efficiency. In 2019, New York City introduced unprecedented legislation targeting the operational energy consumption of the existing building stock. The intent of Local Law 97 is to impose increasingly rigorous limitations on greenhouse gas emissions from buildings 25,000 sq. ft. or greater. Based on current building utility data, approximately 75% of buildings subject to this legislation will not comply with limits set for 2030. Consequently, this legislation is expected to lead building owners to pursue energy modeling to predict future energy usage and evaluate various energy conservation measures. Energy models for existing buildings must be calibrated on the basis of current HVAC equipment, operational schedules, occupancy rates, lighting loads, process loads, facade construction, climatic data, and historical utility consumption. When dealing with existing buildings, documentation is often not available regarding the as-built conditions of the building systems or enclosure performance. To develop an energy model, assumptions must be made regarding the building enclosure, including the opaque thermal performance, air exfiltration and infiltration, fenestration performance, or the presence of thermal bridging. These assumptions can result in conservative inputs that do not reflect the built condition. The building enclosure performance has a direct impact on the operational performance of the HVAC systems and therefore the overall building energy consumption. This paper explores the impact of variations in building enclosure performance assumptions on the overall building energy usage. It provides recommendations for investigative methods to quantify the performance of the existing building enclosure to improve modeling accuracy. These methods include but are not limited to instrumentation to determine in situ R-values, blower door testing to measure air infiltration and exfiltration, and National Fenestration Rating Council simulation to define fenestration performance. Finally, this paper determines the relative importance of each variable in energy model calibration.
