Surface wind responses to mesoscale sea surface temperature over western boundary current regions assessed by spectral transfer functions

Satellite observations have revealed that mesoscale sea-surface temperature (SST) perturbations can exert distinct influence on sea-surface wind by modifying the overlying atmospheric boundary layer. Recently, spectral transfer functions have shown to be useful to elucidate the wind response features. Spectral transfer functions can represent spatially lagged responses, their horizontal scale dependence and background wind speed dependence. By adopting the transfer function analysis, the present study explores seasonality and regional differences in the wind response over the major western boundary current regions. Transfer functions estimated from satellite observations are found to be largely consistent among seasons and regions, suggesting that the underlying dominant dynamics are ubiquitous. Nevertheless, the wind response exhibits statistically significant seasonal and regional differences depending on background wind speed. When background wind is stronger (weaker) than 8.5 m s−1, the wind response is stronger (weaker) in winter than in summer. The Agulhas Retroflection region exhibits stronger wind response typically by 30 % than the Gulf Stream and Kuroshio Extension regions. Although observed wind distributions are reasonably reconstructed from the transfer functions and observed SST, surface wind convergence zones along the Gulf Stream and Kuroshio Extension are underrepresented. The state-of-the-art atmospheric reanalysis and regional model represent well the structure of the transfer functions in the wavenumber space. The amplitude is, however, underestimate by typically 30 %. The transfer function analysis can be adapted to many other atmospheric responses besides sea-surface wind, and thus provide new insights into the climatic role of the mesoscale air-sea coupling.
A robust‐link controller placement model for large‐scale software defined networks

The software defined network (SDN) is a novel flexible network architecture. For the purpose of facilitating management, multiple controllers need to be placed in large‐scale SDN. When a link failure occurs, the path can be re‐planned by the control layer. However, unreasonable controller placement scheme brings about a sharp latency increase between controllers and switches. The reliability of the SDN is therefore affected. To this end, we define a link robust distance (LRD) by considering the states during link failures and non‐link failures. Then, we use it design a robust link controller placement model (RLCPM) which can reduce the impact of link failures on the delay between the controller and the switch. In addition, we design a heuristic algorithm with low‐time complexity to solve the RLCPM more effectively. Experimental results show that, compared with other models, RLCPM simplifies the controller placement problem when considering a link failure. The maximum latency between controllers and switches of the obtained controller placement scheme is lower.
Behavior of the welded tubular joint in spatial lattice shell structures

The welded tubular joint is widely used in ocean platforms,bridges,high rise or long span structures due to the convenient construction,low cost and large capacity.There is a lack of clear and definite design code for the complex tubular joint subjected to axial force,moment and torsion in spatial lattice shell structure.It is necessary to analyze the performance of tubular joint under different complex load conditions.In this paper,the welded tubular joint of a Beijing spatial lattice shell structure was analyzed.The elastic and plastic performance were calculated by finite element method and two different joint types were discussed to improve the joint behavior.The results indicate that the joint stiffness is weakened by local stress concentration.The rib in joint can control the plastic zone development and increase the joint bearing capacity.
Effect of Different Irrigation Rates and Organic Amendments on Sandy Loam Soil Productivity for Peanut Crop

Two experiments wereperformed in 2019 and 2020 to study the effect of the irrigation levels and organic amendmentson nutrientavailability and peanut productivityAmendmentsas ton/fed were 5 tons of compost, 5 tons of farmyard manure and 50 kg/fed of humic acid. Irrigation as m/fed were 1652, 2203 and 2754 in the first season but were 1555, 2074 and 2592 in the second one as 60, 80 and 100 % of ETc. respectively. Higher availabilityof N, P, K, Fe, Mn and Zn occurred in farmyard manuredsoils under irrigation rates comparing with other organic amendments. Increasingirrigation water increased available N and Mn in the soil, but was not significant for P, K, Fe and Zn. All used organic amendments caused a significant increase in growth parameters and productivity. The highest growth parameters and productivity were associatedwith composttreatment with all rates of irrigation compared with other treatments of organic amendments. Growth parameters were notaffectedbyirrigation ratesexcept for branched plants. The interaction between irrigation rates and organic amendments were significant for growth parameters. Adding organic amendments with and without irrigation water rates increased N, P, K, Fe, Mn and Zn concentrations in the seeds, while the high increases were found with compost combined with different rates comparing with other treatments of organic amendments. The effect of irrigation rates on nutrients concentration in the seeds was not significant except when organic amendments was applied.
Far away and yet so close: urban–rural linkages in the context of multilocal work arrangements

ABSTRACT Digital technologies allow knowledge workers to work from multiple locations in both urban and rural areas, creating urban–rural linkages. Information and communication technologies (ICTs) play a critical role. We used a novel mixed-methods approach to combine quantitative data from laptop and smartphone tracking with qualitative data from ethnographic walk-along observations and semi-structured interviews to analyse the creation of urban–rural linkages and temporary proximity in multilocal work arrangements. The results show that multilocal knowledge workers create urban–rural linkages on demand, thereby generating temporary proximity between the urban and the rural. Yet, the economic embedding of these workers in the rural is limited.
A Coordinated Control Method for Integrated System of Wind Farm and Hydrogen Production: Kinetic Energy and Virtual Discharge Controls

This paper proposes a novel coordinated control method of wind farms (WFs) and hydrogen production systems (HPSs). In a grid-connected system where the WF and the HPS are connected to the grid, the WF can supply the power to the grid, producing hydrogen in the HPS. Moreover, the output fluctuation of the WF can be mitigated when the HPS produces hydrogen from the output surplus. The purpose of the grid-connected system is to smooth the WF output fluctuation sufficiently, produce hydrogen constantly, and maintain a high capacity factor in the HPS. The proposed coordinated control achieves the mitigation of the WF output and the high capacity factor in the HPS. The key ideas are 1) utilizing the kinetic energy of wind generators and 2) virtual discharge of the HPS. The fluctuation components of the WF output are compensated by both the WF and the HPS. The proposed coordinated controller enables us to produce hydrogen constantly in the HPS with a low-rated power. The advantage of the proposed coordinated control is verified by a comparative analysis with conventional methods through simulations using real wind data.
Leaf nutrient resorption differs among canopy and understory plant species in subtropical Eucalyptus and Acacia plantations

Although plants are known to conserve nutrients by resorbing them from senescing leaves, how resorption of foliar macro‐ and micronutrients is affected by plant growth form (e.g., trees, shrubs, and ferns) and forest age are not well understood. The current study was conducted in four subtropical monoculture plantations: Eucalyptus and Acacia plantations in 14 and 35 years old, respectively. Leaf resorption efficiencies (REs) and resorption proficiencies (RPs) of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), and manganese (Mn) of the canopy trees and understory shrubs and ferns were determined. N, P, and K but not Ca and Mn were generally resorbed from senescing leaves. RE was significantly higher for P than N, indicating that P was more limiting than N in the subtropical plantations. Nutrient REs did not differ with plantation age, while nutrient RPs generally tended to be lower in the 14‐year‐old than in the 35‐year‐old plantations. REs significantly differed among canopy and understory plant species with different growth forms, that is, NRE, PRE, and KRE values were much higher in woody plants (especially the canopy tree species) than in ferns. REs were correlated with foliar nutrient concentrations but not with soil nutrient concentrations. Our findings suggest that resorption of nutrients from senescing leaves differs among canopy and understory plants, and implicate that introducing native tree species into these plantations could be implemented for accelerating the community succession and further improving the multifunctionality.
Organizational change capability: a systematic review and future research directions

Purpose The purpose of this paper is to systematically review existing research on organizational change capabilities (OCC), which remains fragmented. This study aims to fill gaps in the literature by scientifically discussing contributions and highlighting the main issues with previous research findings regarding the dimensions that comprise them, as well as the antecedents and consequences of OCC. Design/methodology/approach This paper searched all research that studied OCC and published from 2005 to 2020. In total, 48 studies out of 249, found on Scopus and EBSCO-host, were included in the review. Findings This research found that OCC is a complex concept and that it has many definitions and dimensions. The findings also suggest that existing research has found that a number of organizational and individual factors are antecedents of OCC and have consequences for organizational outcomes. Research limitations/implications This review was only conducted on scientific publications from two article databases. Future research should search other databases on OCC as the broad concept may provide additional insights. Originality/value Literature on OCC is limited, and there is still no generally accepted definition of OCC, the different perspectives and measurement dimensions. On the other hand, for academics and practitioners, this study provides a comprehensive, critical systematization of the limited OCC academic literature. This study also offers opportunities for further research to address the limitations of empirical testing of OCC constructs, antecedents and consequences of the various theories and methodologies.
The Evolution of Search: Three Computing Paradigms

Search is probably the most common activity that humans conduct all the time. A search target can be a concrete item (with a yes or no answer and location information), an abstract concept (such as the most important information on the Web about Xindong Wu), or a plan/path for a specific target with an objective function (like flight scheduling with a minimal travel time), among others. In this article, we propose a Universal Connection Theorem (UCT) to suggest that all physical objects/items in the universe are connected through explicit or implicit relationships. Search is to explore the relationships, using different computing methods, to retrieve relevant objects. Under the UCT theorem, we summarize mainstream search approaches into two categories from the user perspective, deterministic search vs. abstract search, and further distinguish them into three computing paradigms: planning based search, data driven search, and knowledge enhanced search. The planning based paradigm explores search as a planning process in a large search space, by graph traversing with heuristic principles to locate optimal solutions. The data driven paradigm seeks to find objects matching the user's query from a large data repository. Indexing, hashing, information retrieval, and recommendations are typical strategies to tackle the data volumes and select the best answers for users’ queries. The knowledge enhanced search does not aim to find matching objects, but to discover and then meet user's search requirements through knowledge mining. The evolution of these three search paradigms, from planning to data engineering and knowledge engineering, provides increasing levels of challenges and opportunities. This article elaborates the respective principles of these paradigms.
Risk Exposure to Legionella pneumophila during Showering: The Difference between a Classical and a Water Saving Shower System

The increase in legionellosis incidence in the general population in recent years calls for a better characterization of the sources of infection, such as showering. Water-efficient shower systems that use water-atomizing technology have been shown to emit slightly more inhalable particles in the range of bacterial sizes than the traditional systems; however, the actual rate of bacterial emission remains poorly documented. The aim of this study was to assess the aerosolisation rate of the opportunistic water pathogen Legionella pneumophila during showering with one shower system representative of each technology. To achieve this objective, we performed controlled experiments inside a glove box and determined the emitted dose and viability of airborne Legionella. The bioaerosols were sampled with a Coriolis® Delta air sampler and the total number of viable (cultivable and noncultivable) Legionella was determined by flow cytometry and culture. We found that the rate of viable and cultivable Legionella aerosolized from the water jet was similar between the two showerheads: the viable fraction represents 0.02% of the overall bacteria present in water, while the cultivable fraction corresponds to only 0.0005%. The two showerhead models emitted a similar ratio of airborne Legionella viable and cultivable per volume of water used. Therefore, the risk of exposure to Legionella is not expected to increase significantly with the new generation of water-efficient showerheads.
Innovation in Construction Megaprojects

AbstractThe construction industry is often criticized for its lack of innovation. Yet, that same industry designs and builds the largest projects of the world—megaprojects. This discrepancy begs the question, whether lack of innovation is a valid description of the construction industry. A megaproject seems ideal to test the construction industry for its innovation potential. For the collection and analysis of data, longitudinal action research, combined with a case study approach, provides the required level of detail and an understanding of interdependencies. The BangNa Expressway in Thailand serves as the focal case; it is the largest bridge in the world. The following aspects are primary contributions to the stock of knowledge: we identify 58 innovations, some are product or construction technology innovations, others are within the technical, management, or contractual organization. This magnitude attests to the ability of the construction industry to innovate on a level not yet identified. The whole.
Electrocoagulation Removal of Sunset Yellow Dye from Aqueous Solution Using Aluminum Electrode

Electrocoagulation (EC) is a technique in which a sacrificial electrode is used to induce the synthesis of certain coagulants. It's a straightforward and cost-effective solution. This makes it a popular method for removing contaminants from water and wastewater. The EC unit with two aluminium metal electrodes is used in this procedure. To remove the dye Sunset Yellow from aqueous solution, we set out to create a novel EC using aluminium electrodes as an anode. Direct current removal of the dye was used to verify the method's efficacy, and the effects of the applied current density were taken into account. The effects of pH, starting dye concentration, and electrolysis time were explored and adjusted for.
First documented case of Myhre syndrome in Romania: A case report

Myhre syndrome is a rare genetic autosomal dominant connective tissue disorder, characterized by developmental delay, characteristic facial features, various bone and joint abnormalities, distinctive cardiovascular, ophthalmological and ear, nose and throat (ENT) manifestations, in association with mild to moderate intellectual disability and autism or autism spectrum disorder-like behaviour. The diagnosis of Myhre syndrome is established corroborating the clinical findings with SMAD4 heterozygous mutation identified in the majority of the patients. SMAD4 gene mutations result in abnormal TGF-β signalling in several cell types, which affects the development of several body systems and leads to the specific phenotype of Myhre syndrome. We herein report the case of an 18-year-old female patient who was diagnosed at the age of 17 years with Myhre syndrome, the first documented case of this syndrome in Romania. Sequence analysis of protein-coding genes using whole-exome analysis identified a ‘de novo’, heterozygous missense variant of SMAD4, c.1498A>G, p. (Ile500Val), which is pathogenic for Myhre syndrome. Although this condition is rare, a series of particularities were identified in the present case, consisting of severe allergic reactions, recurrent ENT tumour development and delayed dental eruption, which have not been described in Myhre syndrome to date, to the best of the authors' knowledge.
Nanotechnology in Cosmetics and Cosmeceuticals—A Review of Latest Advancements

Nanotechnology has the potential to generate advancements and innovations in formulations and delivery systems. This fast-developing technology has been widely exploited for diagnostic and therapeutic purposes. Today, cosmetic formulations incorporating nanotechnology are a relatively new yet very promising and highly researched area. The application of nanotechnology in cosmetics has been shown to overcome the drawbacks associated with traditional cosmetics and also to add more useful features to a formulation. Nanocosmetics and nanocosmeceuticals have been extensively explored for skin, hair, nails, lips, and teeth, and the inclusion of nanomaterials has been found to improve product efficacy and consumer satisfaction. This is leading to the replacement of many traditional cosmeceuticals with nanocosmeceuticals. However, nanotoxicological studies on nanocosmeceuticals have raised concerns in terms of health hazards due to their potential skin penetration, resulting in toxic effects. This review summarizes various nanotechnology-based approaches being utilized in the delivery of cosmetics as well as cosmeceutical products, along with relevant patents. It outlines their benefits, as well as potential health and environmental risks. Further, it highlights the regulatory status of cosmeceuticals and analyzes the different regulatory guidelines in India, Europe, and the USA and discusses the different guidelines and recommendations issued by various regulatory authorities. Finally, this article seeks to provide an overview of nanocosmetics and nanocosmeceuticals and their applications in cosmetic industries, which may help consumers and regulators to gain awareness about the benefits as well as the toxicity related to the continuous and long-term uses of these products, thus encouraging their judicious use.
Consumption tax and productive government expenditure in DSGE model

Abstract Our article presents a dynamic stochastic general equilibrium (DSGE) model to derive effects of a consumption tax rate increase. In the DSGE model, money and inflation are examined to elucidate the transitional path of policy. Results of a consumption tax rate increase are intuitive: GDP declines because of lower aggregate consumption. With a consumption tax rate increase, we consider the productive government expenditure model. In the standard DSGE model, the production function comprises inputs of capital stock and labor. Policy can change the capital stock and labor inputs to alter the production level. However, the production level can be changed by other policies. For instance, increased public investment in infrastructure by government can change the production level. After setting the DSGE model with productive government expenditure, we attempt derivation of a result. We consider the case in which additional productive government expenditure is financed by a consumption tax. In this case, compared with the case of a consumption tax increase without productive government expenditure, GDP increases even if the consumption tax rate is raised. An increase in productive government expenditure increases marginal labor productivity, thereby raising the wage rate. Consequently, by virtue of a raised wage rate, consumption can increase even if the consumption tax negatively affects aggregate consumption.
Hyperforin and Myrtucommulone Derivatives Act as Natural Modulators of Wnt/β-Catenin Signaling in HCT116 Colon Cancer Cells

The therapeutic activities of natural plant extracts have been well known for centuries. Many of them, in addition to antiviral and antibiotic effects, turned out to have anti-tumor activities by targeting different signaling pathways. The canonical Wnt pathway represents a major tumorigenic pathway deregulated in numerous tumor entities, including colon cancer. Here, we investigated the acylphloroglucinols hyperforin (HF) from St. John’s wort (Hypericum perforatum L.) and myrtucommulone A (MC A) from myrtle (Myrtus communis) and semi-synthetic derivatives thereof (HM 177, HM 297, HM298) for their effects on Wnt/β-catenin signaling. None of these substances revealed major cytotoxicity on STF293 embryonic kidney and HCT116 colon carcinoma cells at concentrations up to 10 μM. At this concentration, HF and HM 177 showed the strongest effect on cell proliferation, whereas MC A and HM 177 most prominently inhibited anchorage-independent growth of HCT116 cells. Western blot analyses of active β-catenin and β-catenin/TCF reporter gene assays in STF293 cells revealed inhibitory activities of HF, MC A and HM 177. In line with this, the expression of endogenous Wnt target genes, Axin and Sp5, in HCT116 cells was significantly reduced. Our data suggest that the acylphloroglucinols hyperforin, myrtucommulone A and its derivative HM 177 represent potential new therapeutic agents to inhibit Wnt/β-catenin signaling in colon cancer.
