Avaliação da eficiência técnica de clones de eucalipto em escala comercial: uma abordagem empregando Data Envelopment Analysis (DEA)
Authors: Silva Paulo Henrique da , Ignácio Paulo Sérgio de Arruda , Silva Alessandro Lucas da , Pacagnella Júnior Antônio Carlos
Published: June 2020

O presente artigo refere-se à utilização da metodologia de análise de envoltória de dados (DEA) para determinar e comparar a eficiência técnica de clones de eucalipto dos gêneros Eucaliptus urophylla e Eucaliptus grandis, em escala comercial, produzidos no período de 2016 e 2017 e com idades de corte entre 5 e 7 anos. O plantio desses clones ocorreu em locais com solos arenosos, clima quente e temperado, destinados à produção de celulose e papel, pertencentes a uma empresa situada no interior do estado de São Paulo. Este estudo visa  identificar quais clones apresentam ou não melhorias de eficiência técnica relacionadas a sua idade de corte, podendo auxiliar na tomada de decisão das melhores idades de corte e também quais clones deverão ser excluídos ou mantidos nos próximos ciclos produtivos. O cálculo da eficiência técnica e de seus valores atuais, folgas, alvos e benchmarks ao longo dos anos são determinados através das variáveis custo total; volume individual e volume produzido, sendo utilizado o modelo DEA BCC-O, em função da existência de pouca proporcionalidade de alguns pares input-output. Os clones CL02, CL03, CL05 e CL08 mostraram-se eficientes em ambas as idades de corte, caracterizando-os como possíveis benchmarks para os clones ineficientes. Já o clone CL04 foi o único cuja eliminação da lista de clones a serem utilizados nos próximos ciclos de plantio foi sugerida, apresentando diminuição de seu volume individual e densidade básica, quando ocorre o aumento de sua idade de corte. Conclui-se que a metodologia DEA é uma opção para o auxílio da tomada de decisão de quais clones de eucalipto devem ser utilizados, reduzidos e/ou eliminados de seu próximo ciclo, determinando quais são mais eficientes, verificando sua evolução em relação a sua idade de corte.

Authors: Scarascia Pietro Oliveira , Leite Eliana Cardoso , Valente Roberta Averna
Published: June 2020

Diante dos diversos métodos de mensuração da integridade biótica de determinada área de floresta evidencia-se a Avaliação Ecológica Rápida (AER). Com base na AER foi desenvolvido um índice para avaliar a condição da vegetação, denominado Índice de Integridade Biótica (IIB). A aferição e precisão deste índice retratam o quão íntegro um dado ecossistema florestal se encontra no momento da análise. O alicerce para a eficiência na aplicação do IIB está na escolha correta dos indicadores de integridade biótica, ou seja, nas variáveis a serem mensuradas. O presente estudo partiu de um índice anteriormente proposto para Floresta Estacional Semidecidual (FES), e teve como objetivo adaptar o IIB para uso em área de Floresta Ombrófila Densa no Estado de São Paulo, bem como testar sua eficiência no diagnóstico da integridade de fragmentos de Floresta Ombrófila Densa (FOD) inseridos em matriz rural. Dos onze indicadores presentes no método original, alguns foram mantidos como no original ou adaptados, alguns retirados e alguns novos foram criados. O IIB adaptado foi aplicado numa área de FOD de 70 hectares. Para isso, foram utilizadas 20 parcelas de 10x10m, dentro da área amostral. Os resultados mostraram uma variação do IIB entre 28 e 47, ou seja, 2 parcelas registraram integridade baixa, 11 integridade média e 7 integridade boa. A área como um todo apresentou integridade regular, o que era esperado devido ao seu tamanho, ao entorno agrícola e ao histórico de perturbações. O IIB mostrou-se adaptado e eficiente para análise da integridade biótica da FOD, pois conseguiu mostrar a diferença de integridade entre diferentes trechos de Floresta Ombrófila Densa. Os indicadores menos eficientes foram: “cobertura de serapilheira” e “espécies exóticas lenhosas”. Os mais eficientes foram: “Euterpe edulis”, “epífitas”, “clareiras” e “cipós/lianas”.
Previsão e interação dos preços da celulose brasileira nos mercados interno e externo
Authors: Reichert Bianca , Souza Adriano Mendonça
Published: June 2020

A produção e a exportação de celulose são componentes importantes da economia no país. O objetivo desta pesquisa foi prognosticar o preço nos mercados interno e externo da celulose brasileira e avaliar a interferência entre o preço médio da celulose vendida em atacado e o preço médio da celulose exportada pelo Brasil. O estudo utilizou dados oriundos do Informativo Florestal do Centro de Estudos Avançados em Economia Aplicada (CEPEA), coletados entre junho de 2008 a março de 2018. Os modelos Autorregressivos Integrados de Médias Móveis (ARIMA) foram utilizados para prognosticar o preço da celulose em atacado e exportada pelo Brasil e, para analisar a inter-relação dessas variáveis, foi aplicado modelo Vetor Autorregressivo (VAR). Observou-se que o preço da celulose em atacado e da celulose exportada sofrem oscilações em períodos semelhantes, devido à relação direta com a cotação do dólar e com as crises financeiras nos países importadores. O modelo de melhor acurácia para prognosticar o preço da celulose em atacado foi o modelo ARIMA (1,1,0) enquanto o modelo ARFIMAX (1, d*,0) obteve o melhor desempenho para prognosticar o preço da celulose exportada. A partir da modelagem VAR, verificou-se a existência de inter-relações entre as variáveis, as quais transpareceram o forte impacto do preço da celulose em atacado sobre o preço da celulose exportada pelo Brasil. Assim, as metodologias empregadas foram eficazes para prognosticar e analisar as inter-relações entre as variáveis.
Mixed Martial Arts og det totale engagement
Authors: Rosenwanger Mariam , Lee Eva , Ravn Susanne
Published: June 2020

Mixed Martial Arts is a relatively new staging of the ultimate battle between two practitioners fighting in a cage. With it’s brutality it challenges the practitioner’s physical limits and mental barriers. In this article we go behind – or maybe rather before – the fight and describe the training practices of American MMA practitioners. Accordingly, the aim of this article is to describe the community of practices which MMA practitioners are part of – ‘backstage’ – when preparing for their fight(s).

To answer these questions a discourse analysis of health and diets seen through a historical perspective is made. Gathering and analyzing articles, adverts and diets do this from the weekly magazines, from respectively 1953, 1973, 1993 and 2013. The project is built on a social-constructivist foundation.
At kende grænsen
Authors: Kristensen Marlene Paulin
Published: June 2020

Artiklen tager udgangspunkt i to tidspunkter i den dansk-tyske grænses nyere historie, hvor håndhævelsen af grænsekontrol har været under forandring. Det første tidspunkt er Danmarks indtræden i Schengen-arbejdet i 2001, hvor al permanent grænsekontrol blev fjernet fra den dansk-tyske grænse. Det andet tidspunkt er genindførelsen af midlertidig grænsekontrol i 2016 i kølvandet på ’den Europæiske flygtningekrise’ i 2015. Gennem en analyse af de danske politibetjentes spekulationer over, hvad der fremover vil ske på grænsen, sætter artiklen fokus på hverdagens analytiske arbejde, der gør det muligt at genkende grænsen som en grænse. Hvor åbningen af grænser i begyndelsen af 2000’erne blev stærkt associeret med Europas fremtid, har den tilbagevendte grænsekontrol sat spørgsmålstegn ved udsagnet om, at Europas fremtid er lig med åbne grænser. Artiklen taler sig derfor også ind i bredere diskussioner af hvad, der fremover vil kunne genkendes som de rette grænser for et europæisk fællesskab.
Yüksek Hızlı FPGA ile Yeni Bir LFSR Tabanlı 32-Bit Kayan Noktalı Rastgele Sayı Üreteci Tasarımı
Authors: DERELİ Serkan
Published: June 2020

Bu çalışmada IEEE 754 kayan noktalı sayı
standardına uygun “0” ile “1” arasında 32-bit rasgele sayı üretimi
gerçekleştiren sayısal bir devre tasarımı gerçekleştirilmiştir. Bu sayısal
devrede rasgele sayılar 32-bit uzunluğunda doğrusal geri beslemeli kayan yazmaç
(LFSR) yöntemi ile üretilmekte olduğundan dolayı tekrarlama periyodu son derece
uzundur. Rasgele sayılar üretilirken sola kaydırma işlemi 24-bit üzerinden
gerçekleştirilmiş, MSB tarafındaki ilk dört bit sabit bırakılırken ikinci dört
bit ise LSB tarafındaki ilk dört bitin değerine göre üç değer arasından
seçilmiştir. Çünkü “0” ile “1” arasındaki sayıların alabileceği değerler
incelendiğinde MSB ilk dört bitin sabit olduğu ikinci dört bitin ise sadece üç
değer alabildiği gözlemlenmiştir. Üretilen sayıların normal bir dağılıma sahip
olabilmesi adına tasarlanan sayısal devrede 0 – 24 bit arasından seçilen iki
bitin özel veya işleminden geçirilmesinden sonra elde edilen değerin 0.bit
olarak atanması ve diğer bitlerin sola kaydırılması şeklinde
gerçekleştirilmiştir. Sayısal devre VHDL donanım tanımlama dili ile tasarlanmış,
test işlemleri ise Vivado IDE arabirimi vasıtasıyla simüle edildikten sonra
Xilinx Nexys 4 DDR FPGA aygıtı ile gerçekleştirilmiştir.

Inter-Rater Agreement under Stratified Random Sampling Scheme
Authors: YILMAZ Ayfer , AKTAŞ ALTUNAY Serpil
Published: June 2020

Kappa coefficient is a popular statistic to measure
the agreement between the classifications of two raters. The estimator of the coefficient
and its variance are approximately satisfied by a simple random sampling method.
To get more efficient results for confidence interval estimation of kappa,
stratified random sampling method can also be used, alternatively. In this
study, a bootstrap method under stratified sampling is suggested to use to
estimate the confidence interval of kappa coefficient. The results are
discussed over three data sets.

Authors: YILMAZ Bülent , YAMAN Volkan
Published: June 2020

In this paper we compared the Daftardar-Jafari Method (DJM) with Adomian Decomposition Method (ADM) and Differential Transformation Method (DTM) in solving nonlinear boundary value delay differential equations of pantograph type. All these 3 methods provide series solutions to the problems. We analysed the first n-term approximate solutions of these 3 methods with 2 numerical examples to see if DJM is as good as ADM and DTM in solving nonlinear boundary value delay differential equations and we found DJM a reliable method in solving this kind of problems.

АРХИВИ И ХРИШЋАНСКА КУЛТУРА (НЕКЕ ПРЕТПОСТАВКЕ НАСТАНКА И РАЗВОЈА ЕВРОПСКЕ АРХИВСКЕ МИСЛИ)
Authors: ПИЛИПОВИЋ РАДОВАН
Published: June 2020

У раду се дају основне црте развоја архивистике, односно њен настанак се поставља у контекст културолошког одређења од XVI века до новијег времена. Архивистика, као дисциплина која се технички и суштински бави писаним документима, родила се у хришћанској цивилизацији. Западно и источно хришћанство производе не само верске списе, него и велику количину правно-административних докумената. Однос према тим текстовима био је прагматичан. Они су имали моралну вредност, као и потврду неких економских или јуридичких повластица. Савремена историјска наука развила се кроз кри-тички приступ како религиозним списима (Свето Писмо, житијна књижевност, литургијски текстови) тако и правним документима, тј. прагматичкој писмено-сти (повељама и исправама).
РОМЕЈСКИ МУНИЦИПИЈ БАЛОИЕ У ДАНАШЊЕМ ШИПОВУ
Authors: ЈАНДРИЋ ЖЕЉКО
Published: June 2020

У античком добу, након доласка Римљана, на ужем подруч-ју града Шипова развило се значајно управно и привредно средиште. Епи-графски налази потврдили су да је насеље имало ранг муниципија, а један од налаза потврдио је и његово име – Балоие. Судећи по налазима, ово насеље је ранг муниципија добило крајем I или на почетку II вијека. Центар овог муници-пија налазио се на локалитету Громиле, гдје су лоцирани форум, храм, курија и статуа патрону. Зенит је досегло током III и IV, a уништено је и угашено крајем VI вијека. Ο релевантности насеља ове античке агломерације говоре богати археолошки налази. На основу до данас евидентираног и истраженог, значај-нија концентрација налаза из античког периода своди се на локалитете Громи-ле, Тук, Волари, Црквина, ушће ријеке Лубовице, Чифлук и Мујџићи. На основу археолошких остатака препознају се трагови насеља и рефугија, кул-турних грађевина нехришћанског и хришћанског карактера, те други артефак-ти. Већи број храмова чији су остаци пронађени на размјерно ограниченом подручју, од Волара до Мујџића, указују на то да је Балоие у римском и визан-тијском периоду било и важно црквено сједиште, док неки извори указују и на постојање епископије Балоие.

ТЕКСТИЛНА ИНДУСТРИЈА САРАЈЕВСКЕ ОБЛАСТИ (1918–1928)

Published: June 2020

У раду је приказано стање текстилне индустрије Сарајевске области у периоду између 1918. и 1928. Прва деценија послије Првог свјетског рата била је праћена потражњом за текстилним производима, па је отворено више мањих фабрика за производњу различитих текстилних артикала. Поред њих, истражене су и обновљене фабрике, основане за вријеме Аустроугарске. Наведени су капацитети, производња и број радника у мјери у којој су то изво-ри допуштали, будући да у посматраном периоду нису вођени статистички подаци за текстилну индустрију.Текстилна производња имала је карактер кућног обрта и била је органи-зована на начин да се кућна производња сеоских слојева становништва сачува, унаприједи и прилагоди домаћем и страном тржишту. Сеоско становништво је потребе за текстилним предметима подмиривало кућним обртом, па је унутра-шње тржиште било ограничено на мале градске средине, док је у иностранство извозила само једна фабрика.Иако је веома мали број становништва био запослен у текстилној инду-стрији, иста је имала битну улогу у почецима индустријализације Сарајевске области и Босне и Херцеговине, као и у погледу представљања народне тек-стилне индустрије изван граница Краљевине Срба, Хрвата и Словенаца. Посе-бан допринос је дала побољшању економског положаја жена.

Body, technology and death in posthuman perspective
Authors: Krushinovskaya Ekaterina Georgievna
Published: June 2020

The object of this research is the relevant representations of death, which in many ways are defined by the ideas and practices of embodiment of posthumanism. Special attention is given to correlation between natural and artificial in a human. The article analyzes the corporeal context of death and technical context of body, the interaction of which leads to creation of the project of technogenic immortality. In the present situation, body as a preset biological structure is determined as mortal. Immortality, in this case, is understood as the achievement of post-corporeal state. The work is based on the philosophical-anthropological concepts of innate “biological insufficiency” and “eccentric positionality” of a human that also form his ability to transcending the determinate being. Culture is viewed as the functional expansion of human body. The conclusion is made that the idea of modetnity consists in liberation of human from any external determination, in other words, in autopoiesis. Due to this fact, humanity attempts to transcend the power over own body into the limits of its basic properties – to get rid of death. Posthuman future is achieved through subsequent destruction of “naturalness” of the body.

The ability to modulate the efficacy of synaptic communication between neurons constitutes an essential property critical for normal brain function. Animal models have proved invaluable in revealing a wealth of diverse cellular mechanisms underlying varied plasticity modes. However, to what extent these processes are mirrored in humans is largely uncharted thus questioning their relevance in human circuit function. In this study, we focus on neurogliaform cells, that possess specialized physiological features enabling them to impart a widespread inhibitory influence on neural activity. We demonstrate that this prominent neuronal subtype, embedded in both mouse and human neural circuits, undergo remarkably similar activity-dependent modulation manifesting as epochs of enhanced intrinsic excitability. In principle, these evolutionary conserved plasticity routes likely tune the extent of neurogliaform cell mediated inhibition thus constituting canonical circuit mechanisms underlying human cognitive processing and behavior.

Predictive biomarkers of response to immune checkpoint inhibitors (ICI) help to identify cancer patients who will benefit from immunotherapy. Protein kinase, DNA‐activated, catalytic subunit (PRKDC) is an important gene for DNA double‐strand break (DSB) repair and central T‐cell tolerance. We aimed to investigate the association between PRKDC mutations and tumor mutation burden (TMB), tumor microenvironment (TME), and response to ICI. Whole‐exome sequencing data of 4023 solid tumor samples from the Cancer Genome Atlas (TCGA) and panel‐based sequencing data of 3877 solid tumor samples from Geneplus‐Beijing, China, were used to analyze the TMB. The mRNA expression data of 3541 solid tumor samples from TCGA were used to explore the effect of PRKDC mutations on the TME. Four ICI‐treated cohorts were analyzed for verifying the correlation between PRKDC mutations and the response to ICI. In both the TCGA and Geneplus datasets, we found that the TMB in PRKDC mutation samples was significantly higher than in PRKDC wild‐type samples (P < 0.05 and P < 0.0001, respectively). Further, TCGA datasets showed that PRKDC mutation samples were associated with a significantly increased expression of CD8+ T cells, NK cells, immune checkpoint, chemokines, etc. compared to PRKDC wild‐type samples (P < 0.05). In ICI‐treated cohorts, we also found the PRKDC mutations were associated with increased survival (median PFS, not reached vs. 6.8 months, HR, 0.2893; 95% CI, 0.1255–0.6672; P = 0.0650, Hellmann cohort; median OS, 1184 days vs. 250 days, HR, 0.5126; 95% CI, 0.2715–0.9679; P = 0.1020, Allen cohort), and the increase was significant in multivariate analysis (HR, 0.361; 95% CI, 0.155–0.841; P = 0.018, Allen cohort; HR, 0.240 95% CI, 0.058–0.998; P = 0.050, Hellmann cohort). In summary, we found that PRKDC mutation often appeared to co‐exist with deficiency in some other DNA damage repair mechanism and is nonetheless one of the important factors associated with increased TMB, inflamed TME, and better response to ICI.
Safeguarding the genetic integrity of native pollinators requires stronger regulations on commercial lines

Published: June 2020

Every year more than 1 million commercial bumblebee colonies are deployed in greenhouses worldwide for their pollination services. While commercial pollinators have been an enormous benefit for crop production, their use is emerging as an important threat. Commercial pollinators have been linked to pathogen spillover, and their introduction outside their native area has had devastating effects on native pollinators. A more pervasive but underappreciated threat is their potential impact on the genetic integrity of native pollinators.

We set up a sampling and genotyping‐plus‐phenotyping protocol to evaluate the presence and extent of hybridization between commercial and native individuals of Bombus terrestris in south‐western Spain, a region experiencing a huge propagule pressure of non‐native genotypes due to the massive use of commercial colonies for crop pollination.

Our genomic data show clear evidence of generalized hybridization between native and introduced commercial bumblebee lineages in southern Spain. Only 19% of analysed individuals were assigned with high confidence to the pure native genetic cluster and >45% of sampled specimens were first‐generation hybrids or backcrosses between native and commercial genotypes, indicating that genetic introgression is pervasive in southern Spain.

Although the frequency of commercial genotypes sharply declined with the distance to greenhouses, non‐native alleles have introgressed into native populations inhabiting protected natural parks >60 km away from commercial bumblebee release areas.

As pollination services demand will increase in the coming years, only a more restrictive regulation of commercial lines could mitigate their negative impacts on the genetic integrity of native pollinators, avoid processes of genetic homogenization, and prevent the potential disruption of local adaptations.

Published: June 2020

Although lithium–sulfur (Li–S) batteries are one of the most promising energy storage devices owing to their high energy densities, the sluggish reaction kinetics and severe shuttle effect of the sulfur cathodes hinder their practical applications. Here, single atom zinc implanted MXene is introduced into a sulfur cathode, which can not only catalyze the conversion reactions of polysulfides by decreasing the energy barriers from Li2S4 to Li2S2/Li2S but also achieve strong interaction with polysulfides due to the high electronegativity of atomic zinc on MXene. Moreover, it is found that the homogenously dispersed zinc atoms can also accelerate the nucleation of Li2S2/Li2S on MXene layers during the redox reactions. As a result, the sulfur cathode with single atom zinc implanted MXene exhibits a high reversible capacity of 1136 mAh g−1. After electrode optimization, a high areal capacity of 5.3 mAh cm−2, high rate capability of 640 mAh g−1 at 6 C, and good cycle stability (80% capacity retention after 200 cycles at 4 C) can be achieved.

The biaxial van der Waals semiconductor α‐phase molybdenum trioxide (α‐MoO3) has recently received significant attention due to its ability to support highly anisotropic phonon polaritons (PhPs)—infrared (IR) light coupled to lattice vibrations—offering an unprecedented platform for controlling the flow of energy at the nanoscale. However, to fully exploit the extraordinary IR response of this material, an accurate dielectric function is required. Here, the accurate IR dielectric function of α‐MoO3 is reported by modeling far‐field polarized IR reflectance spectra acquired on a single thick flake of this material. Unique to this work, the far‐field model is refined by contrasting the experimental dispersion and damping of PhPs, revealed by polariton interferometry using scattering‐type scanning near‐field optical microscopy (s‐SNOM) on thin flakes of α‐MoO3, with analytical and transfer‐matrix calculations, as well as full‐wave simulations. Through these correlative efforts, exceptional quantitative agreement is attained to both far‐ and near‐field properties for multiple flakes, thus providing strong verification of the accuracy of this model, while offering a novel approach to extracting dielectric functions of nanomaterials. In addition, by employing density functional theory (DFT), insights into the various vibrational states dictating the dielectric function model and the intriguing optical properties of α‐MoO3 are provided.

Published: June 2020

Antiangiogenesis is a promising approach to cancer therapy but is limited by the lack of tumor‐homing capability of the current antiangiogenic agents. Angiogenin, a protein overexpressed and secreted by tumors to trigger angiogenesis for their growth, has never been explored as an antiangiogenic target in cancer therapy. Here it is shown that filamentous fd phage, as a biomolecular biocompatible nanofiber, can be engineered to become capable of first homing to orthotopic breast tumors and then capturing angiogenin to prevent tumor angiogenesis, resulting in targeted cancer therapy without side effects. The phage is genetically engineered to display many copies of an identified angiogenin‐binding peptide on its side wall and multiple copies of a breast‐tumor‐homing peptide at its tip. Since the tumor‐homing peptide can be discovered and customized virtually toward any specific cancer by phage display, the angiogenin‐binding phages are thus universal “plug‐and‐play” tumor‐homing cancer therapeutics.

The optimal synthesis of advanced nanomaterials with numerous reaction parameters, stages, and routes, poses one of the most complex challenges of modern colloidal science, and current strategies often fail to meet the demands of these combinatorially large systems. In response, an Artificial Chemist is presented: the integration of machine‐learning‐based experiment selection and high‐efficiency autonomous flow chemistry. With the self‐driving Artificial Chemist, made‐to‐measure inorganic perovskite quantum dots (QDs) in flow are autonomously synthesized, and their quantum yield and composition polydispersity at target bandgaps, spanning 1.9 to 2.9 eV, are simultaneously tuned. Utilizing the Artificial Chemist, eleven precision‐tailored QD synthesis compositions are obtained without any prior knowledge, within 30 h, using less than 210 mL of total starting QD solutions, and without user selection of experiments. Using the knowledge generated from these studies, the Artificial Chemist is pre‐trained to use a new batch of precursors and further accelerate the synthetic path discovery of QD compositions, by at least twofold. The knowledge‐transfer strategy further enhances the optoelectronic properties of the in‐flow synthesized QDs (within the same resources as the no‐prior‐knowledge experiments) and mitigates the issues of batch‐to‐batch precursor variability, resulting in QDs averaging within 1 meV from their target peak emission energy.

Published: June 2020

Compared with thin‐film morphology, 1D perovskite structures such as micro/nanowires with fewer grain boundaries and lower defect density are very suitable for high‐performance photodetectors with higher stability. Although the stability of perovskite microwire‐based photodetectors has been substantially enhanced in comparison with that of photodetectors based on thin‐film morphology, practical applications require further improvements to the stability before implementation. In this study, a template‐assisted method is developed to prepare methylammonium lead bromide (MAPbBr3) micro/nanowire structures, which are encapsulated in situ by a protective hydrophobic molecular layer. The combination of the protective layer, high crystalline quality, and highly ordered microstructures significantly improve the stability of the MAPbBr3 single‐crystal microwire arrays. Consequently, these MAPbBr3 single‐crystal microwire‐array‐based photodetectors exhibit significant long‐term stability, maintaining 96% of the initial photocurrent after 1 year without further encapsulation. The lifetime of such photodetectors is hence approximately four times longer than that of the most stable previously reported perovskite micro/nanowire‐based photodetector; this is thought to be the most stable perovskite photodetector reported thus far. Furthermore, this work should contribute further toward the realization of perovskite 1D structures with long‐term stability.
Glycosaminoglycan‐Induced Emissive J‐Aggregate Formation in a meso‐Ester BODIPY Dye

Published: June 2020

The analyte‐directed formation of emissive J‐aggregates of a meso‐ester BODIPY dye is explored in the design of fluorescence “light‐up” probes. The heparin‐specific pyridinium‐functionalized meso‐ester BODIPY dye C10‐Py+ self‐assembles in aqueous buffer into spherical aggregated nanostructures with spectroscopic features indistinguishable from the monomeric dye (signal off). In the presence of heparin, the aggregated assemblies rearrange and associate with heparin through charge‐pairing interactions, triggering the spontaneous formation of emissive J‐type aggregates (signal on). The heparin‐induced J‐aggregate formation of C10‐Py+ provides an excellent “turn‐on” signal with large spectral shifts. The response is highly selective for heparin over other closely related glycosaminoglycan (GAG) analogues, sensitive, fast, and operationally simple. Assays for heparin in human serum, and for the adulterant OSCS in heparin are demonstrated, confirming the reliability and robustness of the J‐aggregation approach using meso‐ester BODIPY dyes in the design of aggregation‐induced emission (AIE)‐based fluorogenic probes.

Published: June 2020

The mechanism by which cell‐penetrating peptides and antimicrobial peptides cross plasma membranes is unknown, as is how cell‐penetrating peptides facilitate drug delivery, mediating the transport of small molecules. Once nondisruptive and nonendocytotic pathways are excluded, pore formation is one of the proposed mechanisms, including toroidal, barrel‐stave, or carpet models. Spontaneous pores are observed in coarse‐grained simulations and less often in molecular dynamics simulations. While pores are widely assumed and inferred, there is no unambiguous experimental evidence of the existence of pores. Some recent experimental studies contradict the mechanistic picture of pore formation, however, highlighting the possibility of a direct translocation pathway that is both nondisruptive and nonendocytotic.

In this work, a model is proposed a model for peptide (linear and dendritic) translocation which does not require the presence of pores and which potentially accords with such experiments. It is suggested that a charged peptide, as it experiences an increasingly hydrophobic environment within the membrane surface, can utilize a proton chain transfer mechanism to shed its protons to counter ions or potentially phospholipid head groups in the membrane skin region, thereby becoming compatible with the hydrophobic interior of the membrane. This increases the likelihood to move into the highly hydrophobic core of the membrane and ultimately reach the opposite leaflet to re‐acquire protons again, suggesting a potential “chameleon” mechanism for non‐disruptive and non‐endocytotic membrane translocation. The molecular dynamics simulations reveal stability of peptide bridges joining two membrane leaflets and demonstrate that this can facilitate cross‐membrane transport of small drug molecules.

Published: June 2020

Incorporating active materials into metamaterials is expected to yield exciting advancements in the unprecedented versatility of dynamically controlling optical properties, which sheds new light on the future optoelectronics. The exploration of emerging semiconductors into terahertz (THz) meta‐atoms potentially allows achieving ultrafast nanodevices driven by various applications, such as biomedical sensing/imaging, ultrawide‐band communications and security scanners. However, ultrafast optical switching of THz radiation is currently limited to a single level of tuning speed, which is a main hurdle to achieve multifunctionalities. Here, a hybrid metadevice which can realize the pump‐wavelength controlled ultrafast switching response by the functionalization of double photoactive layers is demonstrated experimentally. A whole cycle of electromagnetically induced transparency switching with a half‐recovery state changes from 0.78 ns to 8.8 ps as pump wavelength varies from near infrared to near ultraviolet regions. The observed pump‐color selective switching speed changing from nanosecond scale to picosecond scale is ascribed to the wavelength‐dependent penetration length of Ge and the contrasting defect states between noncrystalline Ge and epitaxial Si layers. It is believed that the schemes regarding pump‐color controllable ultrafast switching behavior introduced here can inspire more innovations across the field of ultrafast photonics and can boost the reconfigurable metamaterial applications.

Published: June 2020

Best management practices for switchgrass (Panicum virgatum L.) fertilization in the production of biofuel feedstock and forage hay are variable depending on climate, harvest timing, and variety. A study of N fertilization was conducted to evaluate the yield response, nutrient removal, and nitrogen use efficiency (NUE) in 12 yr old switchgrass stands in Stillwater, OK. Seven rates of N fertilizer were applied ranging from 0 to 235.2 kg N ha−1 for 3 consecutive years (2008, 2009, and 2010). Positive linear trends in yield with increasing rates of N fertilizer (P < .05) were observed in two out of three years. Differences in N removal due to N fertilization were found in all studied years although responses were inconsistent. Nitrogen concentration in harvested biomass increased as N rates and biomass yield increased. Nitrogen use efficiency increased with N rate (P < .05) although many NUE values were negative up to application rate of 100.8 kg N ha−1. Better understanding of nutrient uptake and use efficiency, removal with harvests, and cycling within the plant could provide more refined fertilization practices in switchgrass production.
