The main goal of HIPAA (Health Insurance Portability and Accountability Act) is to protect health information of individuals against access without consent or authorization. Security and privacy are the main issues in HIPAA. A compliant key management solution is used to reduce harm and risk while providing cryptographic mechanisms. Using ECC (Elliptic Curve Cryptography) we ensure more security for access of patient’s health records. This provides same level of security for access of patient’s health records. Patient’s health Information is stored in RFID cards. Finally, the proposed method ensures higher level of security than other existing cryptographic techniques. ECC provides more security even with small key sizes. Proposed scheme describes the various counter measures for improving security and a key recovery mechanism for the protection of keys.

Published: October 2021

Saudi Aramco is the world’s leading oil producer based in Saudi Arabia. Around 1/10th of oil is exported from this organization to the world. Oil production is the major source of revenue for Saudi Arabia and its economy relies completely on it. The Shamoon virus attacked Saudi Aramco in August 2012. The country receives over 80% to 90% of total revenues from the exports of oil and contributes over 40% of the GDP [8]. Shamoon spread from the company's network and removed all of the hard drives. The company was limited only to office workstations and the software was not affected by the virus, due to which all technical operations could have been affected. It was the most disastrous cyber attack in the history of Saudi Arabia. Around 30,000 workstations had been infected by the virus. This paper also discusses the effects of Ransomware which recently attacked Aramco. Apart from that, we will also discuss some suggestions and security measures to prevent those attacks.

Published: October 2021

Energy efficiency is a significant challenge in mobile ad hoc networks (MANETs) design where the nodes move randomly with limited energy, leading to acceptable topology modifications. Clustering is a widely applied technique to accomplish energy efficiency in MANET. Therefore, this paper designs a new energy-efficient clustering protocol using an enhanced rain optimization algorithm (EECP-EROA) for MANET. The EROA technique is derived by integrating the Levy flight concept to the ROA to enhance global exploration abilities. In addition, the EECP-EROA technique intends to proficiently select CHs and the nearby nodes linked to the CH to generate clusters. Moreover, the EECP-EROA technique has derived an objective function with different input parameters. To showcase the superior performance of the EECP-EROA technique, a brief set of simulations takes place, and the results are inspected under varying aspects. The experimental values pointed out the betterment of the EECP-EROA technique over the other methods.

Published: October 2021

The Internet of Things (IoT) has become a hot popular topic for building a smart environment. At the same time, security and privacy are treated as significant problems in the real-time IoT platform. Therefore, it is highly needed to design intrusion detection techniques for accomplishing security in IoT. With this motivation, this study designs a novel flower pollination algorithm (FPA) based feature selection with a gated recurrent unit (GRU) model, named FPAFS-GRU technique for intrusion detection in the IoT platform. The proposed FPAFS-GRU technique is mainly designed to determine the presence of intrusions in the network. The FPAFS-GRU technique involves the design of the FPAFS technique to choose an optimal subset of features from the networking data. Besides, a deep learning based GRU model is applied as a classification tool to identify the network intrusions. An extensive experimental analysis takes place on KDDCup 1999 dataset, and the results are investigated under different dimensions. The resultant simulation values demonstrated the betterment of the FPAFS-GRU technique with a higher detection rate of 0.9976.

INVESTIGAÇÃO DA PERCEPÇÃO DE NASALIDADE VOCÁLICA NO PORTUGUÊS DO BRASIL
Authors: Souza Maria das Graças Amaral de
Published: November 2021

Objetivou-se, com o presente trabalho, investigar qual a porção da vogal nasal é responsável por desencadear o processo de percepção da nasalidade vocálica no Português Brasileiro, e avaliar se há interferência da consoante subsequente nesse processo. Para tanto, gravamos o sinal acústico com corpus composto de 58 palavras com estrutura silábica CVC.CV, nas quais as vogais /a/, /i/ e /u/ ocupam núcleo silábico da primeira sílaba, e a posição de onset da segunda sílaba foi ocupada por consoantes obstruintes. Posteriormente, manipulamos esse sinal, dividimos as vogais nasais /aN/, /iN/ e /uN/ em três porções: inicial, medial e final. Os resultados mostraram que a divisão da vogal em três partes altera a percepção da nasalidade dependendo da consoante que a segue, reforçando ainda mais a complexibilidade do fenômeno. Seguida tanto de oclusiva quanto de fricativa, a vogal /aN/ nas três porções não apresentou perda de nasalidade. Com a vogal /iN/ a perceptibilidade da nasal não foi recuperada em nenhuma das três porções quando seguida de oclusiva bilabial surda e da fricativa alvéolo palatal. A vogal /uN/ nas três porções em que foi dividida, quando seguida de oclusivas velar, alveolar e bilabial sonoras, foi percebida com recuperação da nasalidade.

TRAJETÓRIA DO MAIS-QUE-PERFEITO: CONTRIBUIÇÕES PARA A HISTÓRIA DO PORTUGUÊS POPULAR DE VITÓRIA DA CONQUISTA – BA
Authors: Rocha Sivonei Ribeiro
Published: November 2021

Esta pesquisa trata da função de anterioridade a um ponto de referência passado. A este respeito, acreditamos que tal função está codificada no português por meio de outras categorias verbais, além do mais-que-perfeito composto, tais como o pretérito perfeito, evidenciando que a forma simples do mais-que-perfeito parece estar em extinção. Para tanto, esta pesquisa se insere dentro do quadro teórico do Funcionalismo Linguístico. E para comprovar empiricamente isso, verificamos os dados do corpus do Grupo de Pesquisa em Linguística Histórica e em Sociofuncionalismo/CNPQ da região urbana de Vitória da Conquista, na Bahia. Ao discutirmos as noções de tempo, aspecto e ponto de referência, procuramos demonstrar que tal função, até certo ponto, não está vinculada apenas à forma verbal, mas perpassa por toda sentença, sendo inclusive reforçados por advérbios de tempo. Acreditamos que a função de anterioridade não é exercida apenas pelo mais-que-perfeito, outros verbos exercem tal função de igual modo, o que, todavia, não é citado pelas gramáticas de cunho normativo. Os resultados obtidos evidenciam também que a função de anterioridade a ponto de referencia passado é reforçada por outras categorias além da verbal, como os advérbios e até mesmo os contextos em que determinadas sentenças são ditas. Com isso, ficou claro ser necessária uma ampliação das noções comumente definidas nos manuais de gramática para a definição do mais- que-perfeito, o que ao fazermos, teremos que revisitar, junto aos contextos funcionais deste tempo verbal, as noções de tempo, aspecto e ponto de referência em literaturas especializadas. A selecionar falantes com baixa escolaridade, acreditamos que a função de anterioridade está relacionada à heterogeneidade dos utentes. Assim, ao afirmar que o contexto comunicativo é importante, para compreender a dinâmica da língua no que respeita ao fenômeno em estudo, trazemos ao interior de nossa análise o Funcionalismo, teoria linguística que inter-relaciona forma e função, vistas de maneira dinâmica e adaptável às situações de comunicação. Esta pesquisa faz-se necessária para que futuros estudiosos do fenômeno em discussão encontrem nela caminhos problematizarem suas reflexões. Assim, nosso objetivo é ampliar a discussão sobre tempo verbal que, haja vista, é um campo muito rico para que mais pesquisas tenham mais desdobramentos, e assim, possamos conhecer cada vez mais a nossa língua.

Disease Prevention and Health Promotion Strategies: The Possible Side Effects of Their Good Intentions
Authors: Msomphora Mbachi Ruth , Larsen Anette Iren Langås
Published: October 2021

The public health policies are principally implemented using two main strategies, namely, the population strategy and the high-risk strategy. The purpose of this article is to discuss possible side effects of the good intentions of these two main strategies. The discussions herein are made based on our perspectives and literature study methodology. Main findings portray that the disease prevention and health strategies are applied on a skewed basis, and more so, they are mainly based on medical culture and take little account of human culture. This implies that in order for individuals to comply with the health authorities’ demands, they must give up their own lifestyle coping-strategies that are contradictive to the demands. Hence, the possible side effects of the disease prevention and health promotion strategies’ good intentions; as the strategies have no explicit mandate to change the cultural norms and values. Therefore, we argue that adaptations to make the strategies more inclusive may promote public healthcare in the sense that it can work for everyone’s lifestyle, as individuals can easily take healthy actions in the normal course of their lives.

Authors: Ling Chao , Amponstira Fuangfa
Published: October 2021

Based on the perspective of social network, the study of motivational human resource management practice on employee behavior has far-reaching significance for theory and reality. This paper explores the relationship between the two dimensions of motivational human resource management practice and employee role behavior. Mainly use statistical software such as SPSS, AMOS, and HLM to conduct exploratory factor analysis, correlation analysis, regression analysis, and mediating effect analysis of data. It shows Motivational Human Resource Management Practices (MHRMP) is positively correlated with employee behavior; MHRMP is positively correlated with job embeddedness; Job embeddedness mediates the relationship between MHRMP and employee behavior. This paper adopts a cross-level research method, the research level is from the organizational level to the individual level. The discussion of motivational human resource management practice and employee individual behaviors can also provide references for the construction of cooperative human resource practices.
Growth and Yield Losses of Roundup Ready Soybean as Influenced by Micro-rates of 2,4-D
Authors: Cuvaca Ivan , Knezevic Stevan , Scott Jon , Osipitan O. Adewale
Published: October 2021

Widespread resistance to glyphosate has made weed control very challenging. In response, new approaches to managing resistant biotypes such as the Enlist E3TM have been developed. This technology allows in-crop use of 2,4-D but there is fear associated with unintentional application of the herbicide (e.g. direct application, tank contamination, or spray drift) to sensitive crops. A study was conducted to evaluate Roundup Ready (RR) soybean growth and yield loss as influenced by 2,4-D [six micro rates of 1/5, 1/10, 1/50, 1/100, 1/500 and 1/1000 of the 1,120 g ae ha-1 label recommended dose, and a check with no herbicide applied] applied at V2, R1 and R2 growth stages. In general, RR soybean was more sensitive to 2,4-D at R1 than V2 and R2. The highest 2,4-D rate, 1/5 of the label recommended rate, caused 51% soybean injury symptom, 13 d canopy closure delay, 41.2% plant height reduction, and 68.9% yield loss at R1. Based on effective dose (ED) estimates, 37.7 g ae ha-1 2,4-D caused 5% yield loss (0.23 Mg ha-1) at R1 compared with a 2.5- and 2.0-fold higher dose at V2 and R2, respectively. With respect to number of days to canopy closure, both reproductive stages (R1 and R2) were equally less sensitive to 2,4-D than the vegetative one (V2) as the plants had already achieved maximum growth recorded. On the other hand, ED estimates for plant height have shown that both V2 and R2 were equally more sensitive to 2,4-D than R1. These results clearly indicated that RR soybean growth and yield loss were significantly influenced by the timing of exposure and amount of 2,4-D.

T-MIS: Transparency Adaptation in Medical Image Segmentation
Authors: Somani Ayush , Singh Divij , Prasad Dilip , Horsch Alexander
Published: November 2021

We often locate ourselves in a trade-off situation between what is predicted and understanding why the predictive modeling made such a prediction. This high-risk medical segmentation task is no different where we try to interpret how well has the model learned from the image features irrespective of its accuracy. We propose image-specific fine-tuning to make a deep learning model adaptive to specific medical imaging tasks. Experimental results reveal that: a) proposed model is more robust to segment previously unseen objects (negative test dataset) than state-of-the-art CNNs; b) image-specific fine-tuning with the proposed heuristics significantly enhances segmentation accuracy; and c) our model leads to accurate results with fewer user interactions and less user time than conventional interactive segmentation methods. The model successfully classified ’no polyp’ or ’no instruments’ in the image irrespective of the absence of negative data in training samples from Kvasir-seg and Kvasir-Instrument datasets.
Attention U-Net ensemble for interpretable polyp and instrument segmentation
Authors: Yeung Michael
Published: November 2021

The difficulty associated with screening and treating colorectal polyps alongside other gastrointestinal pathology presents an opportunity to incorporate computer-aided systems. This paper develops a deep learning pipeline that accurately segments colorectal polyps and various instruments used during endoscopic procedures. To improve transparency, we leverage the Attention U-Net architecture, enabling visualisation of the attention coefficients to identify salient regions. Moreover, we improve performance by incorporating transfer learning using a pre-trained encoder, together with test-time augmentation, softmax averaging, softmax thresholding and connected component labeling to further refine predictions.
Autism Spectrum Disorder (ASD): From Molecular Mechanism to Novel Therapeutic Approach
Authors: Friedman Hagit
Published: November 2021

Autism spectrum disorder (ASD) is the joint name for neurodevelopmental impairments characterized by abnormal social interaction, communication difficulties, limited range of activities and areas of interest, and typical motor impairments. There is a remarkable increase in the prevalence of ASD over the past 30 years. Studies indicate that genetic, neurological, and environmental factors are involved in the emergence of ASD, and recent works describe the neuromolecular mechanism implicated in the basis of ASD. 3LT has now developed into a therapeutic procedure that is used for three main goals: to reduce inflammation, edema, and chronic orthopedic disorders; to promote healing of wounds, deeper tissues, and nerves; and to treat neurological injuries and pain. 3LT may treat neurological injuries by lowering levels of inflammation proteins and by stimulation of mitochondria to increase the production of adenosine triphosphate and neural growth factors. This review aims to discuss the current evidence for the effects and mechanisms of 3LT at the cellular level and the effects of 3LT-induced changes in brain development and function. Early and effective intervention, through the developmental time window of high ASD susceptibility, using tools that are directed to the mechanism of pathology, may minimize neurological and functional deficits.
Surfactants and Their Applications for Remediation of Hydrophobic Organic Contaminants in Soils
Authors: Saint-Fort Roger
Published: November 2021

Soil contaminated with ubiquitous hydrophobic organic contaminants (HOCs) is a worldwide recurring concern arising from their indiscriminate disposal, improper management, and accidental spills. A wide range of traditional remedial strategies have been the common practice. However, these treatment methods have become cost prohibitive, not environmental friendly, and less accepted by society. Surfactant-enhanced remediation technology represents a cost-effective and green technology alternative to remediate such contaminated sites. Surfactant remediation technologies are conducted in-situ or ex-situ as two broad categories, or in combination. Among these technologies are soil flushing, washing, phytoremediation, and bioremediation. More applied research continues to quantify the efficiency of surfactant-enhanced mass transfer phase using a single surfactant solution while their binary blends to remove mixed HOCs in soils are also a focus of interest for research. There is a great potential to develop novel synthetic and biosurfactants that will exhibit higher biodegradability, less toxicity, higher removal efficiency, more economical and more recyclable. This work thus provides a review of the applications and importance of surfactant-enhanced remediation of soil contaminated with HOCs. Relevant environmental factors, soil properties, surfactant chemistry, mechanisms, mass transfer phase, and field designs are summarized and discussed with purposes of providing greater context and understanding of surfactant-enhanced remediation systems.
Colonialism, Human Rights, and Abortion in Ireland
Authors: Connelly Rachel
Published: November 2021

This essay explores the role of narratives in the field of the Irish abortion debate. In specific, it explores the different types of narratives that both the pro-choice and pro-life groups manipulate in order to draw support from The Irish populace. The author explains that the pro-choice groups employ political-legal narratives To argue for the right to abortion whereas historical narratives and anti-British sentiments are more commonly found within pro-life narratives. However, the true purpose of the pro-life narratives is to prevent the secularization and liberalization of Ireland's laws, thereby maintaining the patriarchy at the top of the social hierarchy. However, with the 2018 referendum on the constitutional ban on abortion resulting in a liberalization of Ireland's abortion laws, the lack of success on The pro-life end is revealed, and a possible wave of liberalization may follow to permanently shift the social hierarchy.
Discrimination on Gender Binary Campuses
Authors: Xu Wei
Published: November 2021

In recent years, transgender people have both grown in numbers and visibility in the united states. However, the issue of discrimination against transgender people has been a serious and widespread phenomenon in today's society. This paper discusses the transgender issues at large and how the issues negatively affect transgender students' college experiences in a variety of ways, including but not limited to institutions' failure to include "gender identity" in their nondiscrimination policies. The evidence from scholarly sources also suggests that religiously affiliated, single-sex and two-year colleges typically offer few protections for transgender students. Finally, the paper will examine institutions' past initiatives on the subject matter and provide recommendations for institutions to create a more gender-friendly environmnent.
INSIGHTS ON THE ECONOMIC ESTIMATES OF THE CLIMATE COSTS OF THE AVIATION SECTOR DUE TO AIR MANAGEMENT IN 2018-19

Published: November 2021

Air navigation service providers ensure that aircrafts keep safely apart by prescribing vertical and horizontal distances to each other. In the European Union and its associated members, regulation is carried out via a performance scheme which measures and sets targets for the different key performance areas. For the environmental area, targets in terms of CO2 and other pollutants were set by assuming that there would be continuous improvements for the Key performance Environment indicator based on actual trajectory. However, although a higher Horizontal Flight Efficiency (HFE) measurement usually means a more direct flight trajectory, this does not necessarily translate into a climate optimal trajectory. Thus, vertical flight efficiency also needs to be considered. There is also an interdependency be¬tween airspace and Air Traffic Man¬agement Capacity and Environment: when the offered capacity falls short of the demand for flights, ground delays, holdings and traffic shifts to adjacent areas occur. This entails detours and a deterioration of the HFE-indicator.
Results show that total climate costs for 2018 and 2019 may be as high as 1 bn EUR, of which about 34% is due to CO2 emissions. In particular, the climate costs of CO2 emissions due to capacity constraints range from 54 to 301 million EUR, depending on whether CO2 costs are measured in terms of avoidance costs or under the EU Emissions Trading System (EU ETS). Following the first criterion and the short to medium run up to 2030, the estimated costs would amount to 112 million EUR. In the long run, from 2040 to 2060, these costs would amount to 301 Million EUR. With the estimates of the EU ETS, the cost by 2030 would be close to 54 million EUR and 153.5 million EUR for the long run. Volatility of carbon pricing may play a very significant role, but fortunately can be hedged.
Therefore, a shortfall of capacity leads to delay costs and considerable environmental costs. As capacity is planned in the medium to long-term, traffic forecasts are a crucial element. This means that further research is warranted into the interdependency of traffic forecasts, capacity and environmental costs.

Authors: Porča Sanela
Published: November 2021

Svakodnevna pojava širenja govora mržnje putem medija u Bosni i Hercegovini uglavnom je zasnovana na nacionalizmu. Svakodnevno se putem određenih medija propagira međunacionalna netrpeljivost čiji krajnji cilj je nastavak i dovršetak ratnih planova. Jasno je da takav trend održava trenutno stanje i poziciju sva tri nacionalna politička lobija i da su najvjerovatnije te politike finansijeri i organizatori takvih medijskih projekata. Obzirom da ne postoji ni jedan poseban zakon koji reguliše i kažnjava govor mržnje na online platformama, jasno se uočava iskorištavanje tog stanja za ostvarivanje političke koristi. Fokus ovog rada bit će identifikacija i analiza portala koji šire govor mržnje na društvenoj mreži facebook. Facebook je najposjećenija online platforma u Bosni i Hercegovini, pa je iz tog razloga fokus usmjeren na nju. Facebook je pogotovo specifičan zato što otvara mogućnost dvosmjerne komunikacije te se mogu analizirati reakcije korisnika na plasiranje određenih tekstova koji promoviraju govor mržnje. Identifikacija portala koji šire govor mržnje te njihova analiza ima za cilj ukazati na kontekst i ulogu tog alata u rukama političkih elita. Rad sadrži zakonodavni i institucionalni okvir koji se odnosi na slobodu govora i zloupotrebu slobode govora kroz govor mržnje. Govor mržnje je svaki oblik izražavanja koji širi, potiče, promoviše ili opravdava rasnu, nacionalnu ili bilo koju drugu mržnju po osnovu različitosti koje postoje među ljudima.

УТИЦАЈ ИНТЕРНЕТ ЗАВИСНОСТИ НА МЕНТАЛНО ЗДРАВЉЕ МЛАДИХ
Authors: Манић Михајло , Симовић Слободан
Published: November 2021

Аутори у раду истичу да су, интензивна употреба интернета и његов “шарм” последњих година, довели до појаве феномена познатог као “Интернет зависност”. Сам интернет је безопасан алат, али неправилна употреба мреже може повећати ризик од зависности, поремећаја менталног здравља и социјалних односа. Већина људи мисли да је зависност везана само за употребу хемијских састава као што су алкохол, никотин, кокаин и хероин; али стручњаци верују да све што стимулише људско биће и чини да се осећају енергично може изазвати зависност. Лечење зависности није ограничено само на терапију лековима. Кад год навика постане присила, као што је коцкање, дрога, алкохол или чак играње компјутерских игара, ћаскање, сурфовање по мрежи, и то се може сматрати зависношћу. Бихејвиоралне зависности не треба занемарити због недостатка „материјала”. Оно што људе чини зависнима је пријатно искуство у обављању тог понашања, као што се зависници осећају када користе хемијске дроге. У коришћењу интернета, људи постају зависни и то не од „материје - супстанце”, већ се она испољава кроз неконтролисано коришћење рачунара или осећају емоционалне сигурности уз интернет.

Authors: Ševkušić Ljubiša
Published: November 2021

Savremeni način poslovanja od privrednih subjekata zahtijeva veliku fleksibilnost, brzinu djelovanja kao i kontinuirano praćenje zahtjeva tržišta. Sve to rezultat je globalizacije kao procesa koji povećava stepen konkurencije, ali i međuzavisnosti mnogobrojnih učesnika u privredi. Kako bi se stvorio povoljan poslovni ambijent, za rast privredne aktivnosti u sadašnjim uslovima neophodno je osigurati povjerenje investitora (sadašnjih i potencijalnih), kreditora, dobavljača, javnosti, državnih organa i slično. Povećanju nivoa poslovnog povjerenja značajno doprinosi objektivno finansijsko izvještavanje. Ovakvo izvještavanje pored poštovanja zakonske i profesionalne regulative podrazumijeva i etičke norme, odnosno etičko ponašanje kreatora finansijskih izvještaja. Primarni cilj rada jeste da istakne važnost objektivnog finansijskog izvještavanja u uslovima globalizacije.

Органска пољопривреда је вид аграрне производње, који се базира на принципима одрживог развоја и чији је циљ производња квалитетне и здравствено безбедне хране. Органски пољопривредни производи, као висококвалитетни производи, последица су биолошке равнотеже екосистема и органских природних процеса. Иако органска пољопривреда, као вид пољопривредне производње, није доминантна на светском тржишту, присутан је стални раст тражње за њеним производима. То указује на чињеницу да је развој органске пољопривреде у последњих неколико година, па и деценија у непрекидној експанзији. Овај развој одвија се у складу са принципима еколошког менаџмента, као споне између екологије и класичног менаџмента.

High rates of evolution preceded shifts to sex-biased gene expression in Leucadendron, the most sexually dimorphic angiosperms

Differences between males and females are usually more subtle in dioecious plants than animals, but strong sexual dimorphism has evolved convergently in the South African Cape plant genusLeucadendron. Such sexual dimorphism in leaf size is expected largely to be due to differential gene expression between the sexes. We compared patterns of gene expression in leaves among 10Leucadendronspecies across the genus. Surprisingly, we found no positive association between sexual dimorphism in morphology and the number or the percentage of sex-biased genes (SBGs). Sex bias in most SBGs evolved recently and was species specific. We compared rates of evolutionary change in expression for genes that were sex biased in one species but unbiased in others and found that SBGs evolved faster in expression than unbiased genes. This greater rate of expression evolution of SBGs, also documented in animals, might suggest the possible role of sexual selection in the evolution of gene expression. However, our comparative analysis clearly indicates that the more rapid rate of expression evolution of SBGs predated the origin of bias, and shifts towards bias were depleted in signatures of adaptation. Our results are thus more consistent with the view that sex bias is simply freer to evolve in genes less subject to constraints in expression level.

Human mesenchymal stromal cells (hMSCs) are a promising source for regenerative cell therapy. However, hMSC clinical use has been stymied by product variability across hMSC donors and manufacturing practices resulting in inconsistent clinical outcomes. The inability to predict hMSC clinical efficacy, or potency, is a major limitation for market penetration. Standard metrics of hMSC potency employ hMSCs and third‐party immune cell co‐cultures, however, these assays face translational challenges due to third‐party donor variability and lack of scalability. While surrogate markers of hMSC potency have been suggested, none have yet had translational success. To address this, a high‐throughput, scalable, low‐cost, on‐chip microfluidic potency assay is presented with improved functional predictive power and recapitulation of in vivo secretory responses compared to traditional approaches. Comparison of hMSC secretory responses to functional hMSC‐medicated immune cell suppression demonstrates shortcomings of current surrogate potency markers and identifies on‐chip microfluidic potency markers with improved functional predictive power compared to traditional planar methods. Furthermore, hMSC secretory performance achieved in the on‐chip microfluidic system has improved similarity compared to an in vivo model. The results underscore the shortcomings of current culture practices and present a novel system with improved functional predictive power and hMSC physiological responses.

Published: November 2021

Efficient broadband near‐infrared (NIR) emitting materials with an emission peak centered above 830 nm are crucial for smart NIR spectroscopy‐based technologies. However, the development of these materials remains a significant challenge. Herein, a series of design rules rooted in computational methods and empirical crystal‐chemical analysis is applied to identify a new Cr3+‐substituted phosphor. The compound GaTaO4:Cr3+ emerged from this study is based on the material's high structural rigidity, suitable electronic environment, and relatively weak electron–phonon coupling. Irradiating this new phosphor with 460 nm blue light generates a broadband NIR emission (λem,max = 840 nm) covering the 700–1100 nm region of the electromagnetic spectrum with a full width at half maximum of 140 nm. The phase has a high internal quantum yield of 91% and excellent thermal stability, maintaining 85% of the room temperature emission intensity at 100 °C. Fabricating a phosphor‐converted light‐emitting diode device shows that the new compound generates an intense NIR emission (178 mW at 500 mA) with photoelectric efficiency of 6%. This work not only provides a new material that has the potential for next‐generation high‐power NIR applications but also highlights a set of design rules capable of developing highly efficient long‐wavelength broadband NIR materials.

Published: November 2021

We report the synthesis and optoelectronic properties of TIPS‐peri‐pentacenopentacene (TIPS‐PPP), a vertical extension of TIPS‐pentacene (TIPS‐PEN) and a low‐band‐gap material with remarkable stability. We found the synthetic conditions to avoid the competition between 1,2‐ and 1,4‐addition of lithium acetylide on the large aromatic dione. The high stability of TIPS‐PPP is due to the peri‐fusion which increases the aromaticity by generating two localized aromatic sextets that are flanked with 2 diene fragments, similar to two fused‐anthracenes. Like TIPS‐PEN, TIPS‐PPP shows the archetypal 2D brickwall motif in crystals with a larger transfer integral and smaller reorganization energy. The high mobility of up to 1 cm2 V−1 s−1 was obtained in an organic field‐effect transistor fabricated by a wet process. Also, TIPS‐PPP was used as a near‐infrared (NIR) emitter for NIR organic‐light‐emitting‐diode devices resulting in a high external quantum efficiency at 800 nm.

Here we present room‐temperature spin‐dependent charge transport measurements in single‐molecule junctions made of metalloporphyrin‐based supramolecular assemblies. They display large conductance switching for magnetoresistance in a single‐molecule junction. The magnetoresistance depends acutely on the probed electron pathway through the supramolecular wire: those involving the metal center showed marked magnetoresistance effects as opposed to those exclusively involving the porphyrin ring which present nearly complete absence of spin‐dependent charge transport. The molecular junction magnetoresistance is highly anisotropic, being observable when the magnetization of the ferromagnetic junction electrode is oriented along the main molecular junction axis, and almost suppressed when it is perpendicular. The key ingredients for the above effect to manifest are the electronic structure of the paramagnetic metalloporphyrin, and the spinterface created at the molecule–electrode contact.

Nanomaterials offer exciting properties and functionalities. However, their production and processing frequently involve complex methods, cumbersome equipment, harsh conditions, and hazardous media. The capability of organisms to accomplish this using mild conditions offers a sustainable, biocompatible, and environmentally friendly alternative. Different nanomaterials such as metal nanoparticles, quantum dots, silica nanostructures, and nanocellulose are being synthesized increasingly through living entities. In addition, the bionanofabrication potential enables also the in situ processing of nanomaterials inside biomatrices with unprecedented outcomes. In this Minireview we present a critical state‐of‐the‐art vision of current nanofabrication approaches mediated by living entities (ranging from unicellular to higher organisms), in order to expand this knowledge and scrutinize future prospects. An efficient interfacial interaction at the nanoscale by green means is within reach through this approach.
Design of a novel fractional‐order internal model controller‐based Smith predictor for integrating processes with large dead‐time
Authors: Kumar Deepak , Aryan Pulakraj , Raja G. Lloyds
Published: November 2021

A novel multi‐loop control configuration with two controllers is suggested for integrating processes having large dead‐time. The inner‐loop consists of a Smith predictor having proportional (P)/proportional‐derivative (PD) controller for first/second‐order integrating processes, respectively. Once the dead‐time is compensated by the inner‐loop Smith predictor, a fractional‐order internal model controller (FOIMC) is designed in the outer‐loop. The P/PD controllers are tuned using direct synthesis methodology. The proposed control architecture has three adjustable parameters (inner and outer closed‐loop adjustment parameters, fractional‐order of the FOIMC low‐pass filter). Based on extensive simulations, the tuning ranges for the above‐mentioned adjustable parameters are specified. Suitable justification is also provided for the suggested range of tuning parameters. Several benchmark examples of plant models are used to study the set‐point following and disturbance elimination capabilities of the proposed control architecture. Quantitative performance measures are also computed for comparing the suggested and previously reported schemes. It is evident that the suggested FOIMC based Smith predictor yields enhanced control performance than some recently reported techniques.

In this work, an alternative utilization of agro‐industrial waste coconut endocarp (Cocos nucifera L.) as raw material for the synthesis of magnetic adsorbent aiming the phenol removal is proposed. The synthetized adsorbent, denominated magnetic activated carbon (MAC), was prepared by coprecipitation of cobalt ferrite (CoFe2O4) onto activated carbon surface obtained by carbonization of coconut endocarp. Characterization of MAC was carried out by point of zero charge (PZC), Brunauer, Emmett, and Teller (BET) surface area, scanning electron microscopy (SEM), x‐ray fluorescence (XRF), Fourier transform infrared spectroscopy (FTIR), x‐ray diffractometry (XRD) analysis, and magnetization curves. Adsorption experiments were performed in batch system to evaluate kinetics and equilibrium of phenol adsorption. Adsorbent regeneration method was proposed to evaluate the reutilization of MAC in successive cycles of adsorption–desorption. Results showed that obtained magnetic compounds present cubic phase structure covered in activated carbon surface. MAC has microporous structure with functional groups like carbonyl and hydroxyl that can behave as adsorption sites. Kinetic studies indicate that adsorption rate increased rapidly around the initial 60 min, reaching equilibrium at 240 min; following pseudo‐first‐order and pseudo‐second‐order kinetic models in characterization concentrations of 50 and 100 mg L−1, only the second‐order model fit the kinetic data at 150 mg L−1, while both models were outside the chi‐square interval at 200 and 230 mg L−1. The adsorption equilibrium is represented by Langmuir isotherm with high adsorption capacity of 116.0 ± 3.61 mg g−1. The desorption experiments revealed that adsorption capacities of MAC still viable after three adsorption–desorption cycles. It was observed that chemical affinity of small concentrations of methanol with phenol allowed to exert greater desorption capacity to other solvents with permanence of adsorbed phenol of 17.5 mg g−1.

The assessment of climate change impacts in regions with complex orography and land‐sea interfaces poses a challenge related to shortcomings of global climate models. Furthermore, climate indices based on absolute thresholds are especially sensitive to systematic model biases. Here we assess the effect of bias adjustment (BA) on the projected changes in temperature extremes focusing on the number of annual days with maximum temperature above 35°C. To this aim, we use three BA methods of increasing complexity (from simple scaling to empirical quantile mapping) and present a global analysis of raw and BA CMIP5 projections under different global warming levels. The main conclusions are (1) BA amplifies the magnitude of the climate change signal (in some regions by a factor 2 or more) achieving a more plausible representation of future heat threshold‐based indices; (2) simple BA methods provide similar results to more complex ones, thus supporting the use of simple and parsimonious BA methods in these studies.

Published: November 2021

Lithium‐ion batteries (LIBs) have the advantages of high energy density, stable working voltage, long cycling life, and no memory effect. They have been widely used as power sources for electric vehicles (EVs) and hybrid electric vehicles (HEVs). However, during periods of usage or storage, some unfavorable factors such as thermal runaway, volumetric expansion, and growth of lithium dendrites can severely reduce the reliability and safety of LIBs. Therefore, an accurate health estimation system and a reliable life expectancy strategy toward LIBs have been proved significantly important. However, due to the large volume and high price, most characterization methods in the laboratory cannot be applied directly to commercial electric devices. Therefore, small portable monitor methods are more practical. In this review, we first systematically reviewed the recent progress of modeling methods towards LIBs. Some typical modeling strategies (e. g., thermal models, electrical models and aging models) and advanced sensors which can be imbedded in LIBs are emphatically introduced and compared. At last, some promising directions of development on portable in‐situ monitor strategies are also predicted and supposed.
