Development of a Framework for Cost–Benefit Analysis of I-Head and T-Head Groynes Based on Scour and Turbulent Flow Characteristics
Authors: Mall Manish , Priyanka  , Hari Prasad K. S. , Ojha C. S. P.
Published: October 2023

River bank protection is a vital component of sustainable development. This study investigates and compares the scour and flow features around two different types of groynes, an unsubmerged I-head groyne (IHG) and T-head groyne (THG), to provide insights into their performance and efficiency in river reaches. Experiments were conducted to examine the scouring pattern, mean and turbulent flow characteristics including 3D mean flow velocity distribution, Reynolds stresses, turbulent kinetic energy, and bed shear stress near the bed region around the groynes under similar flow conditions. The results indicated that THG had a maximum equilibrium scour depth over three-fold greater than IHG. For both the IHG and THG cases, it was observed that there is a direct correlation between the location of maximum negative vertical velocity and its magnitude to the region of maximum local scour and its depth. All the stresses of high magnitude are found along the propagation of the detached shear layer profile, which turns back sharply downstream towards the bank containing the IHG while remaining mostly away from the bank in the case of THG. The effective bank protection length was estimated to be two-fold the groyne length in the case of IHG and three-fold the groyne transverse length in the case of THG. Cost–benefit analysis of the two groyne types shows IHG as the more cost-efficient groyne with respect to bank protection lengths. This study provides valuable insights for developing design methodologies aimed at promoting the wider utilization of different head-shape groynes in river reaches and aids in selecting appropriate groyne head configurations that align with specific field requirements.

Published: October 2023

Under the background of large-scale PV (photovoltaic) integration, generating typical operation scenarios of power systems is of great significance for studying system planning operation and electricity markets. Since the uncertainty of PV output and system load is driven by weather factors to some extent, using PV output, system load, and weather data can allow constructing scenarios more accurately. In this study, we used a TimeGAN (time-series generative adversarial network) based on LSTM (long short-term memory) to generate PV output, system load, and weather data. After classifying the generated data using the k-means algorithm, we associated PV output scenarios and load scenarios using the FP-growth algorithm (an association rule mining algorithm), which effectively generated typical scenarios with weather correlations. In this case study, it can be seen that TimeGAN, unlike other GANs, could capture the temporal features of time-series data and performed better than the other examined GANs. The finally generated typical scenario sets also showed interpretable weather correlations.

Published: October 2023

Nowadays, recycling of construction and demolition waste (C&DW) is a challenging opportunity for the management of such end-of-life (EOL) materials through alternative methods to environmentally unsustainable methods (i.e., landfilling). In order to make recycling processes more effective, quality control systems are needed. In this work, the possibility of developing a sensor-based procedure to recognize different demolition waste materials from a recycling perspective was explored. An automatic recognition of different predefined constituent classes of recyclables (i.e., concrete, mortar, natural stones, unbound aggregates, clay masonry units, bituminous materials) and contaminants (i.e., glass, metals, wood, cardboard, and gypsum plaster), as established by an European standard, was carried out using hyperspectral imaging (HSI) working in the short-wave infrared (SWIR) range (1000–2500 nm). The implemented classification strategies, starting from the collected hyperspectral images of the analyzed constituents, allowed for the identification of the different material categories. Two main models were built for identifying contaminants in recyclable materials and categorizing material groups based on technical specifications. The results showed accurate category identification with Sensitivity and Specificity values over 0.9 in all models. The possibility of performing a full detection of C&DW recycling products can dramatically contribute to increasing the quality of the final marketable products and their commercial value, at the same time reducing the amount of waste and the consumption of primary raw materials.

Published: October 2023

In order to study the catastrophe law of small hidden faults along the floors of deep quarries under the coupled conditions of high stress and strong seepage, this paper proposes a concept of damage structure that can replace the overall performance of a population of tiny fracture swarms within a non-homogeneous rock mass. Numerical simulation software is used to simulate and analyze the influence of damage structure on the evolution of surrounding rock, regarding its plastic zones, shear stress, and displacement, and the pore water pressure distribution in small hidden faults along coal seam floors. This study shows that under the influence of damage structure, the shear stress of the rock above the fault shows “N”-type change, the displacement of the surrounding area shows “S”-type change, and the shear stress of the rock below the fault and the pore water pressure above the fault show “M”-type change. The damage structure changes the performance of the coal seam floor’s water barrier by reducing the strength of the rock surrounding the fault, blocking the release rate of the shear stress of the surrounding rock, weakening the support pressure of the fault, reducing the degree of expansion of the surrounding rocks and shifting the direction of concentration of the pore water pressure. The results of this study can provide a reference for technology for water damage prevention and control of coal seam floors containing small hidden faults, under the influence of non-homogeneous rock bodies.

Published: October 2023

This study aims to explore how work disengagement (WD) is affected by employees’ perceptions of distributive injustice (DI). It also investigates the mediating roles of workplace negative gossip (WNG) and organizational cynicism (OC). Responses were received from the full-time employees of category (A) travel agencies and five-star hotels operating in Egypt. WarpPLS 7.0 was used to run a PLS-SEM analysis on the 656 valid responses. The results revealed that there is a positive relationship between employees’ perception of distributive injustice and work disengagement level; in addition, there is a positive relationship between perception of distributive injustice and workplace negative gossip and organizational cynicism. Results also reported positive relationships between workplace negative gossip, organizational cynicism, and work disengagement. Furthermore, findings showed that workplace negative gossip and organizational cynicism mediate the relationship between distributive injustice and work disengagement. Some groundbreaking investigations were conducted as part of the research. Research on how DI affects WNG, OC, and WD is still lacking. In terms of contextual significance, an empirical investigation of the relationship between these factors in hotels and travel companies is unavailable. By empirically examining these connections in the context of Egyptian hotels and travel agencies, the current study has filled a gap in the literature on tourism and hospitality, human resources management, and organizational behavior.

Published: October 2023

Urban green space (UGS) is an important public infrastructure. However, the rapid development of cities and the insufficient supply and uneven distribution of UGSs have led to a mismatch between them and various needs, which has seriously affected environmental justice and social equity. This study discusses the fairness of UGS from the perspective of supply and demand and improves the theoretical framework of supply and demand combination evaluation. First, this study analyzes the supply of UGSs through accessibility analysis and evaluates their demand from both subjective and objective dimensions. Second, the fairness of UGS is analyzed from a Gini coefficient and spatial evaluation perspective. Finally, the location optimization of UGSs is performed, which provides strategic guidance for the improvement of UGSs in Chengdu. The research results based on Chengdu City show that the travel mode directly affects the supply range of UGSs and is reflected in their fairness. At the same time, in the case of a highly dense population, UGSs in the city are in short supply; that is, the equity is negatively correlated with the population. This study provides a new perspective to evaluate UGS fairness and can be a reference for UGS optimization decisions.

Published: October 2023

In the current era marked by the growing adoption of renewable energy sources, the use of photovoltaic-powered LED streetlights, known for their enhanced efficiency and extended lifespan, is on the rise. This lighting solution encompasses essential components such as a photovoltaic (PV) panel, an energy storage system, LED luminaires, and a controller responsible for supervising power distribution and system operations. This research introduces a novel approach involving a ZVS (zero-voltage switching) bidirectional boost converter to manage the interaction among the PV panel, LED lights, and battery storage within the system. To elevate system efficiency, a modified version of the conventional bidirectional boost converter is employed, incorporating an auxiliary circuit encompassing a capacitor, inductor, and switch. This configuration enables soft switching in both operational modes. During daytime, the converter operates in the buck mode, accumulating solar energy in the battery. Subsequently, at night, the battery discharges energy to power the LED lights through the converter’s boost operation. In this study, the PET (photo-electro-thermal) theory is harnessed, coupled with insights into heatsink characteristics and the application of a soft-switching bidirectional boost converter. This integrated approach ensures optimal driving of the LED lights at their ideal operating voltage, resulting in the generation of optimal luminous flux. The proposed LED lighting system is thoroughly examined, and theoretical outcomes are validated through simulations using the PSCAD/EMTDC version 4.2.1 software platform.
Riemann–Hilbert Problems, Polynomial Lax Pairs, Integrable Equations and Their Soliton Solutions
Authors: Gerdjikov Vladimir Stefanov , Stefanov Aleksander Aleksiev
Published: October 2023

The standard approach to integrable nonlinear evolution equations (NLEE) usually uses the following steps: (1) Lax representation [L,M]=0; (2) construction of fundamental analytic solutions (FAS); (3) reducing the inverse scattering problem (ISP) to a Riemann-Hilbert problem (RHP) ξ+(x,t,λ)=ξ−(x,t,λ)G(x,tλ) on a contour Γ with sewing function G(x,t,λ); (4) soliton solutions and possible applications. Step 1 involves several assumptions: the choice of the Lie algebra g underlying L, as well as its dependence on the spectral parameter, typically linear or quadratic in λ. In the present paper, we propose another approach that substantially extends the classes of integrable NLEE. Its first advantage is that one can effectively use any polynomial dependence in both L and M. We use the following steps: (A) Start with canonically normalized RHP with predefined contour Γ; (B) Specify the x and t dependence of the sewing function defined on Γ; (C) Introduce convenient parametrization for the solutions ξ±(x,t,λ) of the RHP and formulate the Lax pair and the nonlinear evolution equations (NLEE); (D) use Zakharov–Shabat dressing method to derive their soliton solutions. This requires correctly taking into account the symmetries of the RHP. (E) Define the resolvent of the Lax operator and use it to analyze its spectral properties.
Cross-Version Software Defect Prediction Considering Concept Drift and Chronological Splitting
Authors: Kabir Md Alamgir , Rehman Atiq Ur , Islam M. M. Manjurul , Ali Nazakat , Baptista Marcia L.
Published: October 2023

Concept drift (CD) refers to a phenomenon where the data distribution within datasets changes over time, and this can have adverse effects on the performance of prediction models in software engineering (SE), including those used for tasks like cost estimation and defect prediction. Detecting CD in SE datasets is difficult, but important, because it identifies the need for retraining prediction models and in turn improves their performance. If the concept drift is caused by symmetric changes in the data distribution, the model adaptation process might need to account for this symmetry to maintain accurate predictions. This paper explores the impact of CD within the context of cross-version defect prediction (CVDP), aiming to enhance the reliability of prediction performance and to make the data more symmetric. A concept drift detection (CDD) approach is further proposed to identify data distributions that change over software versions. The proposed CDD framework consists of three stages: (i) data pre-processing for CD detection; (ii) notification of CD by triggering one of the three flags (i.e., CD, warning, and control); and (iii) providing guidance on when to update an existing model. Several experiments on 30 versions of seven software projects reveal the value of the proposed CDD. Some of the key findings of the proposed work include: (i) An exponential increase in the error-rate across different software versions is associated with CD. (ii) A moving-window approach to train defect prediction models on chronologically ordered defect data results in better CD detection than using all historical data with a large effect size (δ≥0.427).
Long-Lasting Insecticide-Treated Nets Combined or Not with Indoor Residual Spraying May Not Be Sufficient to Eliminate Malaria: A Case-Control Study, Benin, West Africa

Published: October 2023

In sub-Saharan Africa, despite the implementation of multiple control interventions, the prevalence of malaria infection and clinical cases remains high. The primary tool for vector control against malaria in this region is the use of long-lasting insecticide-treated nets (LLINs) combined or not with indoor residual spraying (IRS) to achieve a synergistic effect in protection. The objective of this study was to assess the effectiveness of LLINs, with or without IRS, protected against Plasmodium falciparum infection and uncomplicated clinical cases (UCC) of malaria in Benin. A case-control study was conducted, encompassing all age groups, in the urban area of Djougou and the rural area of Cobly. A cross-sectional survey was conducted that included 2080 individuals in the urban area and 2770 individuals in the rural area. In the urban area, sleeping under LLINs did not confer significant protection against malaria infection and UCC when compared to no intervention. However, certain neighbourhoods benefited from a notable reduction in infection rates ranging from 65% to 85%. In the rural area, the use of LLINs alone, IRS alone, or their combination did not provide additional protection compared to no intervention. IRS alone and LLINs combined with IRS provided 61% and 65% protection against malaria infection, respectively, compared to LLINs alone. The effectiveness of IRS alone and LLINs combined with IRS against UCC was 52% and 54%, respectively, when compared to LLINs alone. In both urban and rural areas, the use of LLINs alone, IRS alone, and their combination did not demonstrate significant individual protection against malaria infection and clinical cases when compared to no intervention. In the conditions of this study, LLINs combined or not with IRS are not effective enough to eliminate malaria. In addition to the interventions, this study identified factors associated with malaria in Benin as housing design, neglected social groups like gender-marginalised individuals and adolescents, and socio-economic conditions acting as barriers to effective malaria prevention. Addressing these factors is crucial in order to facilitate malaria elimination efforts in sub-Saharan Africa.

Published: October 2023

Antimicrobial resistance (AMR) is included in the ten most urgent global public health threats. Global evidence suggests that antibiotics were over prescribed during the early waves of the COVID-19 pandemic, particularly in low- and middle-income countries. Inappropriate use of antibiotics drives the emergence and spread of antibiotic resistance. This study aimed to examine the impact of COVID-19 on Ni-Vanuatu health worker knowledge, beliefs, and practices (KBP) regarding antibiotic prescribing and awareness of antibacterial AMR. A mixed methods study was conducted using questionnaires and in-depth interviews in 2018 and 2022. A total of 49 respondents completed both baseline (2018) and follow-up (2022) questionnaires. Knowledge scores about prescribing improved between surveys, although health workers were less confident about some prescribing activities. Respondents identified barriers to optimal hand hygiene performance. More than three-quarters of respondents reported that COVID-19 influenced their prescribing practice and heightened their awareness of ABR: “more careful”, “more aware”, “stricter”, and “need more community awareness”. Recommendations include providing ongoing continuing professional development to improve knowledge, enhance skills, and maintain prescribing competency; formalising antibiotic stewardship and infection, prevention, and control (IPC) programmes to optimise prescribing and IPC practices; and raising community awareness about ABR to support more effective use of medications.

Published: October 2023

JC polyomavirus (JCPyV) is a human-specific polyomavirus that establishes a silent lifelong infection in multiple peripheral organs, predominantly those of the urinary tract, of immunocompetent individuals. In immunocompromised settings, however, JCPyV can infiltrate the central nervous system (CNS), where it causes several encephalopathies of high morbidity and mortality. JCPyV-induced progressive multifocal leukoencephalopathy (PML), a devastating demyelinating brain disease, was an AIDS-defining illness before antiretroviral therapy that has “reemerged” as a complication of immunomodulating and chemotherapeutic agents. No effective anti-polyomavirus therapeutics are currently available. How depressed immune status sets the stage for JCPyV resurgence in the urinary tract, how the virus evades pre-existing antiviral antibodies to become viremic, and where/how it enters the CNS are incompletely understood. Addressing these questions requires a tractable animal model of JCPyV CNS infection. Although no animal model can replicate all aspects of any human disease, mouse polyomavirus (MuPyV) in mice and JCPyV in humans share key features of peripheral and CNS infection and antiviral immunity. In this review, we discuss the evidence suggesting how JCPyV migrates from the periphery to the CNS, innate and adaptive immune responses to polyomavirus infection, and how the MuPyV-mouse model provides insights into the pathogenesis of JCPyV CNS disease.

Published: October 2023

Vaccine immunogenicity still represents an unmet need in specific populations, such as people from developing countries and “edge populations”. Both intrinsic and extrinsic factors, such as the environment, age, and dietary habits, influence cellular and humoral immune responses. The human microbiota represents a potential key to understanding how these factors impact the immune response to vaccination, with its modulation being a potential step to address vaccine immunogenicity. The aim of this narrative review is to explore the intricate interactions between the microbiota and the immune system in response to vaccines, highlighting the state of the art in gut microbiota modulation as a novel therapeutic approach to enhancing vaccine immunogenicity and laying the foundation for future, more solid data for its translation to the clinical practice.

Published: October 2023

Anti-roll and anti-pitch are important directions in the comprehensive research of automobiles. In order to improve the anti-roll and anti-pitch performance of the vehicle, an inerter was applied to the vehicle suspension system, and a 14 DOF vehicle nonlinear dynamics model was established. The influence of the change in inertance in the eight kinds of improved ISD (Inerter-Spring-Damper) suspension structures on the RMS (root mean square) value of performance indexes of roll, vertical, and pitch motion of the vehicle was studied. Based on this, the vehicle’s ISD structure with better performance was selected, and the NSGA-Ⅱ algorithm was adopted to optimize the selected structural parameters. The simulation results showed that the four kinds of suspension hadbetter comprehensive performance, and their structureswere, respectively, excluding the supporting spring in parallel, (1) an inerter in series with a spring and a damper in parallel, (2) a damper in series with a spring and an inerter in parallel, (3) an inerter and a damper in series, and (4) the damper in parallel with a spring and an inerter in series. The ISD suspension structure had better comprehensive performance under step steering braking, which was obviously better than the passive suspension, and effectively improved the vehicle ride comfort, anti-roll and anti-pitch performance. Under the hook steering braking, the lateral load transfer rate was used to evaluate the vehicle’s anti-rollover ability. The results showed that the ride comfort and anti-rollover ability of ISD suspension were better than those of passive suspension. Under the condition of taking into account the anti-pitching ability, the suspension consists of a supporting spring in parallel with an inerter, and a damper in series was better.

Published: October 2023

The genusDrepanaphisdel Guercio currently includes 16 species, all of which are found in North America. Representatives of this genus are narrow oligophages associated mainly with plants of the genusAcer.Previous studies have focused only on the morphology of selected species, while not considering their geographical distribution. Among all species, the painted maple aphidDrepanaphis acerifoliaedeserves particular attention, because it represents the broadest range in North America and is the only species of this genus to be found outside of its natural range, i.e. in Europe. Thanks to suitable niche modelling based on a maximum entropy model, we were able to present maps with the potential distribution ofD.acerifoliaein its natural range. In North America, its distribution coincides with the natural range of the host plants (native to the eastern part), as well as the areas where they are planted (the western part). An extrapolation of these results to the area of Europe allowed for the designation of places where the aphids can find suitable climatic conditions for developing and expanding their spatial distribution. The model indicated the Mediterranean basin, almost all of Italy, excluding mountainous areas, Spain, Portugal, France, Belgium, the Netherlands, the western part of Germany, the southeast and central part of Great Britain, Hungary and the Balkan Peninsula. In a more continental view, the model pointed to areas stretching from the middle of eastern Ukraine, including Crimea, through Russia, to northern parts of Kazakhstan along the border with Russia. Additionally, the impact of climate change on the spread of the species within the next 80 years was analysed, both in North America and Europe. Models considering the potential future climate changes indicate thatD.acerifoliaemay find suitable niches further north of its current ranges. In North America, this is mostly areas of eastern Canada, while in Europe it includes the central and eastern part and the Asian part of Russia.

Aplicaciones excesivas de fertilizante nitrogenado (N) son comunes en el Bajío, segunda región productiva de México. El sensor GreenseekerTM determina requerimientos de N, mejora su eficiencia de uso, reduce contaminación e incrementa rentabilidad, pero el algoritmo utilizado para recomendar dosis de N en la etapa de encañe utiliza valores del índice de Vegetación de Diferencia Normalizada (NDVI) de un área rica en nitrógeno (ARN), cuyo establecimiento intensifica el trabajo y dificulta la transferencia tecnológica debido al tamaño reducido de las unidades productivas; por ello, se generó un algoritmo simplificado que no utiliza ARN, empleando el índice de estimación de biomasa por día (INSEY), estimado con el NDVI de 23 lotes fertilizados con dosis de N a la siembra (DFNI) de 0 a 180 kg ha-1 y una ARN de 300 kg ha-1. La validación del algoritmo fue en un ensayo de seis variedades de trigo fertilizadas a la siembra con 0, 46, 69, 92, 115 y 138 kg ha-1 de N y complementadas con las cantidades requeridas en la etapa de encañe (FNR) calculadas con el algoritmo. La ganancia en rendimiento y la precisión de las recomendaciones se determinó con un ensayo similar, pero sin N complementario. El diseño experimental fue bloques completos al azar en parcelas divididas, en la parcela grande se colocaron las DFNI y en la chica las variedades. Se generó la ecuación DN = 274- (11458 × NDVI/DDS) que estimó cantidades de N para el reabono entre 118 y 69 kg ha-1 para complementar las dosis de 46 a 138 kg ha-1 aplicados en la siembra. El rendimiento promedio fue de 7.5 t ha-1, mayor que el promedio regional (5.5 t ha-1) obtenido con hasta 350 kg ha-1 de N.

Der Schuleintritt kann eine kritische Schwelle sowohl im Leben als auch auf dem Bildungsweg eines Kindes darstellen. Eine präventive und gezielte Begleitung von Kindern und ihrer Familien sowie des pädagogischen Fachpersonals an der Schnittstelle vom Kindergarten in die Schule ist daher von besonderer Bedeutung. Ein Beispiel für eine nachhaltige Übergangsbegleitung, die den ökosystemischen Ansatz verfolgt, ist das seit 2017 von bayerischen Frühförderstellen entwickelte Modellprojekt „Schulstarthelfer – Übergangsbegleitung vom Kindergarten in die Schule“. Dieses begleitet und unterstützt Kinder mit Risikofaktoren und ihre Familien während des Übergangs und vernetzt das pädagogische Fachpersonal aus dem vorschulischen sowie schulischen Bereich, um Gelingensfaktoren zu gewährleisten. Um das Modellprojekt erläutern zu können, bedarf es einer kurzen Vorstellung der Arbeit der Frühförderstellen, ehe auf erste Erkenntnisse der Evaluation des Projekts eingegangen wird. (DIPF/Orig.)

Das Grundschullehramt ist im Vergleich zu anderen Studiengängen wenig internationalisiert und hat aktuell wenig institutionell verankerte, international ausgerichtete Lehrangebote. Vor allem wird das Studienumfeld im Lehramt, abgesehen von den fremdsprachlichen Fächern, als wenig international auffordernd wahrgenommen. Die Gießener Grundschullehrer*innenbildung begegnet diesem Desiderat mit einer mehrstufigen Internationalisierungsstrategie (GloPEG 2022). Ziel dieser Strategie ist es, internationale Anteile im Grundschullehramtsstudium nachhaltig zu implementieren und den Studierenden jeweils in selbstbestimmter Intensität und Frequenz internationale Erfahrungen zu ermöglichen. Der erste Schritt der Strategie umfasst die digitale Ringveranstaltung „Selected aspects of pedagogy and didactics in primary schools“ im Rahmen des Virtual International Programme (VIP) der Justus-Liebig-Universität (JLU) Gießen, die im Zentrum dieses Beitrags steht. Nach der folgenden Erläuterung des Konzepts der Lehrveranstaltung werden erste empirische Betrachtungen sowie ausblickende und weiterführende Gedanken zur Internationalisierung des Grundschullehramts aufgeführt.

Teaching and Researching the History and Archaeology of Jordan during the Bronze and Iron Ages (ca. 3600 – 1200 BC)
Authors: Kafafi Zeidan A.
Published: October 2023

The history of nations is their political and cultural identity, but this recorded history, which began with the knowledge of writing in the East about 3200 years BC and has continued until the present, has seen difficulties and declines in civilizations. What concerns us in this article is shedding light on an important period of Jordan’s ancient history – the Bronze and Iron Ages (c. 3600-332 BC) – which scholars of religion and the Bible contect with stories in the Bible beginning with the the Israelites leaving Egypt, their coming to Palestine and their establishing their state. It is important for us to shed light on who undertook and undertakes recording that history and the methodologies followed and the interpretation of antiquities and ancient inscriptions related to that history. We have seen that it is necessary to the extent possible to clarify Jordan’s role in the study of Jordan’s ancient history by the Jordanian universities that study history and archaeology and related fields. Since the establishment of the emirate in 1921, Jordan has attached great importance to archaeology, establishing a Department of Antiquities that remained under the control of the Mandate until the Arabization of the army in 1956. Also, in the same year in which the University of Jordan was established (1962), a Department of History and Archeology was established, and the university sent students abroad to study ancient history. Some other Jordanian universities did likewise. Unfortunately, recent years have seen a decline in research and teaching about the Bronze and Iron Ages; a number of faculty members in this field have retired, and universities have either refrained from sending students abroad or have stopped hiring new faculty members. In addition, the sub-sciences related to archaeology have overshadowed the original, hoping that students will get a job, as a result of graduates in archaeology flooding the market. In order for the matter to be rectified, it is necessary to establish a research center or centers based on scientific research and publishing in the ancient history of Jordan, following a unified approach based on scientific evidence.

OBJETIVO: Descrever o melhor tratamento clínico, segundo as melhores evidências atuais, para endometriose profunda. METODOLOGIA: Trata-se de uma revisão integrativa da literatura, que foi realizada por meio de buscas nas bases de dados eletrônicos National Library of Medicine (PubMed), Biblioteca Virtual em Saúde (BVS) e Scientific Electronic Library Online (SciELO), utilizando os Descritores em Ciências da Saúde (DeCS): “Endometriosis”, “Deep”, “Infiltrative” e “Treatment” em inglês e “Endometriose”, “Profunda”, “Infiltrativa” e “Tratamento” em português, com o operador booleano AND. Foram empregados como critérios de inclusão: artigos publicados entre 2017 e 2022, disponíveis na íntegra, nos idiomas inglês, português ou espanhol que correspondam ao objetivo do estudo. Foram excluidos artigos duplicados, monografias, dissertações, teses e resumos. Os resultados foram apresentados em tabela e em seguida colados em discussão. RESULTADOS E DISCUSSÕES: O tratamento da endometriose profunda pode ser medicamentoso, cirúrgico, ou ambos, sendo direcionado pela idade e sintomas da paciente, extensão, localização e estadiamento da doença, desejam de engravidar e efeitos adversos aos medicamentos. O tratamento medicamentoso tem efeitos positivos, reduzindo o tamanho dos implantes, da infiltração e da vascularização, sendo o tratamento de escolha na ausência de indicações absolutas para cirurgia. O tratamento cirúrgico pode ser feito com laparoscopia ou laparotomia exploradora e deve ser oferecido às pacientes em que o tratamento clínico foi ineficaz ou contraindicado por alguma razão e para aquelas que desejam engravidar espontaneamente. CONCLUSÃO: Observou-se que o tratamento clínico falha em pacientes mais jovens com endometriose de retossigmoide que têm lesões intestinais maiores. No entanto, o tratamento hormonal clínico é tão eficaz quanto a abordagem cirúrgica na redução dos sintomas de dor, com exceção da dispareunia, e apresenta uma taxa menor de complicações em mulheres com endometriose intestinal.

Mid- and long-wavelength IR photodetectors incorporating narrow-bandgap semiconductors often face the challenge of large RT dark current, limiting their applications in military and civilian use. Herein, a novel pBn+ barrier detector architecture based on a lead selenide/indium selenide barrier structure is proposed to significantly suppress the dark current, so that uncooled mid-wave IR (MWIR) photodetectors with high performance can be achieved. The finite element analysis of the detector demonstrates reduced RT dark current down to 55 mA cm−2 under −0.1 V bias, which is a two-fold decrease compared to the InAs/InAsAb type-II superlattice detector. In addition, at RT, the optimized pBn+ barrier detector exhibits excellent responsivity and detectivity of 1.23 A W−1 and 9.47 × 109 cm Hz1/2·W−1 at 3.8 μm, respectively. The PbSe-based barrier architecture provides a promising industrialization solution for high-performance uncooled MWIR photodetectors.

We demonstrated the low-cost, eco-friendly fabrication techniques for inverted perovskite solar cells (iPSCs) with multilayered electron transporting layers using fullerene derivative (PCBM) and ZnO nanoparticles (NPs) by combining the meniscus-coating, push-coating, and transfer-printing techniques. We fabricated the multilayered planar iPSCs by low-temperature printing process not higher than 120 °C. Using meniscus coating method by reciprocating the glass rod back and forth repeatedly for 2–10 times, the material usage of PCBM and toxic chlorobenzene for iPSCs to 1/15 ~ 1/20 compared with the conventional spin-coating method, and 1/10 for ZnO NPs without extending the tact time. The material utilization rate became about 50% and 100% for meniscus- and push-coating, and a pin-hole-free uniform film was obtained for meniscus coating. We also reduced the initial degradation of perovskite layer during the deposition of ZnO onto the perovskite layer and improved the photovoltaic properties by the transfer-printing of ZnO from “wet-PDMS” stamp onto the thin PCBM film coated perovskite layers.

This paper investigates effects of re-occurring oil spillages on cocoyam, Colocasia esculenta (L.). It studies changes in petiole lengths, leaf blades, chlorophyll concentrations in leaves, and PAH and BTEX concentrations in tubers for three generations under diverse conditions. 8 10-gallon grow bags were used: Grow bags 5–8 were treated with a controlled quantity (4 L/cubic metre) of liquid crude hydrocarbon in the months of June 2019–2021; with 2 replications, after a 2-3-day interval within a week. In grow bags 3, 4, 7, and 8, poultry manure were applied once in 2 months after small seedlings emerged from soil surfaces. Grow bags 1 and 2, 3, and 4 served as “controls” for non-contaminated growth. Grow bags 7 and 8 were treated with hydrocarbons and poultry manure. In the first generation, coco yams planted in grow bags 7-8 showed growth responses (average values of 1.04 m, 51 cm, 4.45 mg/g for petiole length, leaf blade length, and chlorophyll concentration, respectively) very similar to coco yams planted in pristine soil with poultry manure with average values of 1.00 m, 50 cm, 3.45 mg/g. The cocoyams planted in pristine organic rich soils showed similar response with or without fertilizers (average values of 0.98 m, 48 cm 1.83mg/g and 1.00m, 50 cm, 3.45mg/g) with progressively smaller leaves as generation increases. The cocoyams in hydrocarbon impacted soils generally perform poorer than uncontaminated soil with or without poultry manure by the second and third generation. Poultry manure on soils with re-occurring hydrocarbon contamination exacerbates soil weakening. Mean PAH and mean BTEX concentrations in tubers were 0.001-0.0035 mg/kg and <0.001mg/kg respectively. Cocoyams are not strong BTEX bioactive scavenger but gradually became more concentrated in PAH.
Time-Domain Channel Estimation for Extremely Large MIMO THz Communications with Beam Squint

Published: October 2023

In this paper, we study the problem of extremely large (XL) multiple-input multiple-output (MIMO) channel estimation in the Terahertz (THz) frequency band, considering the presence of propagation delays across the entire array apertures, which leads to frequency selectivity, a problem known as beam squint. Multi-carrier transmission schemes which are usually deployed to address this problem, suffer from high peak-to-average power ratio, which is specifically dominant in THz communications where low transmit power is realized. Diverging from the usual approach, we devise a novel channel estimation problem formulation in the time domain for single-carrier (SC) modulation, which favors transmissions in THz, and incorporate the beam-squint effect in a sparse vector recovery problem that is solved via sparse optimization tools. In particular, the beam squint and the sparse MIMO channel are jointly tracked by using an alternating minimization approach that decomposes the two estimation problems. The presented performance evaluation results validate that the proposed SC technique exhibits superior performance than the conventional one as well as than state-of-the-art multi-carrier approaches.
