Authors: Degani Marcia , Chariglione Isabelle Patriciá Freitas Soares
Published: November 2019

Através dos sentidos do corpo, o ser humano se constitui e estabelece as suas relações com o mundo. A perda da acuidade sensorial que ocorre com o envelhecimento afeta todos os indivíduos em diferentes níveis, causando transtornos que comprometem a independência, a autonomia, as relações interpessoais e o sentido de identidade. A abordagem Snoezelen, razão das presentes reflexões, tem sido utilizada tanto como conceito, quanto como intervenção terapêutica, visando à adaptação e à melhoria na qualidade de vida dos idosos.   Palavras-chave: Estimulação; Idoso; Sentidos.

Authors: Wibowo Unggul Prasetyo , Ferdianto Anton , Laili Nurul , Yurnaldi Dida , Setiawan Ruli
Published: November 2019

Cisaar Valley is located on the east part of Sumedang Regency, West Jawa Province. It’s close to the boundary of Sumedang-Majalengka Regency. In this location the sandy and clay dominated sedimentary rocks are well exposed along the outcrops in the Cisaar Valley. These sedimentary rocks is inferred from Pliocene-Pleistocene deposits from Kaliwangu and Citalang Formation. Foraminifera microfossil that commonly used for interpretation of depositional environment is rarely found, whereas freshwater mollusk and vertebrate fossils often found in the sediment rocks of this area.  This condition raises a question, what is the environment of this valley in the past? Data obtained from measured stratigraphic sections along Cisaar river and its tributary rivers in Cibengkung and Cirendang hamlets, Jembarwangi village. There are at least three depositional paleoenvironments which from old to young are: shallow marine, estuarine and fluviatil braided channel depositional paleoenvironment.  Characteristics of the lower, middle and upper of the estuarine environment were found in this Cisaar Valley as the evidences of the oceanic regression processes was happened in the past in this area.

Authors: Kopij Grzegorz
Published: November 2019

In 2010, an attempt was made to quantify bird species breeding in the Opava Mts. and their foothill (c. 135 km2, including c. 40 km2 [31%] of forests). The area is situated in the extreme south of Opole Silesia, SSW Poland. For most non-passerine species, total counts were made for the whole area (distribution of their breeding pairs is shown on maps), while for most passerine species, semi-quantitative studies were conducted. A total of 116 breeding and two probably breeding bird species were recorded. Changes in breeding avifauna of the area during the years 1880-2010 are also analysed based on literature search. A total of 134 breeding bird species were recorded over the 130 years. During the years 1990-2010, decreae in numbers has been evidenced for the following species: Perdix perdix, Tetrastes bonasia, Tyto alba, Athene noctua, Corvus frugilegus, and Nycifraga caryocatactes, In the same period, increase in numbers has been documented for species such as: Accipiter gentilis, Falco tinnunculus, Columba oenas, Jynx torquilla, Dryocopus martius, Picus canus, Picus viridis, Motacilla cinerea, Luscinia megarhynchos, Phoenicurus phoenicurus, Saxicola rubicola, Locustella naevia, Locustella fluviatilis, Corvus corax and Corvus cornix. Opava Mts. and its foothills constitute an imporant conservation area. Fifteen species listed in Annex I of the Bird Directive of the E.U. were recorded there, including a sizable population of Ficedula albicollis.
Figure, Ground and the Notion of Equilibria in the Work of Gilbert Simondon and Gestalt theory
Authors: Bellon Jacqueline
Published: November 2019

Based on Clausius’ phrasing of a “transformational content” and the resulting 2nd law of thermodynamics, I demonstrated that Gilbert Simondon’s On the Mode of Existence of Technical Objects is historically situated at the threshold of understanding open systems thermodynamics and the related concepts of balance. Furthermore, I showed that Gestalt theory, as represented by Wolfgang Köhler, at least reproduced, if not partially anticipated or even prepared this development of 20th century thinking. Finally, I gave some short examples of how Simondon applied the figure/ground distinction to human perception, memory, and a general theory of becoming and I introduced his proposal to analyse “the grounds” just as thoroughly as the laws of figuration.
Real time optimization of temperature field in induction heating
Authors: Novák Zdeněk , Kyncl Jan
Published: November 2019

Many induction heating processes must be controlled in accordance with the prescribed time evolution of temperature of the heated body (bodies). This requires a correct setting of field currents (amplitudes and frequencies) in the heating inductors that can vary either continuously or by steps. The paper presents a novel model of induction annealing of cylindrical aluminum billets based on solution of nonstationary forward and inverse tasks. The methodology is described in detail and illustrated with a typical example. Some of the results were verified experimentally.
Research on a novel magnetic tilt sensor designed using Hall elements and ferrofluid
Authors: Öztürk Yavuz , Yariçi Ismail
Published: November 2019

In this study, a simple, adjustable, bidirectional tilt sensor was designed using a pair of linear Hall effect sensors and magnets. Theoretical analysis and experimental results of the sensor system were presented. The working principle of the designed sensor is based on sensing the magnetic field of a mobile magnet which displaces with respect to the tilt angle. Two magnet sets were placed at the two ends of the system to apply repulsive restoring forces on the mobile magnet. The mobile magnet was coated with a light hydrocarbon based ferrofluid as a lubricant to reduce friction. Fixed Hall effect sensors were placed face to face at the two sides of the mobile magnet to monitor the magnetic field of the mobile magnet. It was shown that both experimentally and theoretically, it is possible to measure the approximate tilt angle linearly and quadratically by calculating the sum and difference of the Hall sensor voltages for the relatively small movements of the mobile magnet. Moreover, the system was also examined for the different sets of side magnets. For three different side magnet configurations, approximately 0.7, 1.1 and 1.68 V/rad sensitivity values were observed in the linear range.
Feedback stabilization for one sided Lipschitz nonlinear systems in reciprocal state space: Synthesis and experimental validation
Authors: Thabet Assem , Frej Ghazi Bel Haj , Gasmi Noussaiba , Boutayeb Mohamed
Published: November 2019

This paper proposes a design of a stabilization control for one-sided Lipschitz (OSL) nonlinear systems in new reciprocal state space (RSS) framework. The main objective is to extend the state derivative feedback stabilization methods for a class of nonlinear systems where the nonlinearity of derivatives state satisfies the OSL properties in RSS. The presented controller is composed of a state derivative feedback approach in order to ensure asymptotic stability in the sense of Lyapunov. The first approach deals with the synthesis of a basic controller by adopting a simple transformation of Linear Matrix Inequality (LMI) to standard algebraic Ricatti equation (ARE). The second is an extension to adaptive version with adjustment parameters. High performances are shown through real-time implementation with a hardware in the loop (HIL) mode using digital signal processing (DSP) device (DSpace DS 1104).

The Use of Smart Elements for the Transport Operation in the Slovak Cities
Authors: Bubelíny Oliver , Ďaďová Irina , Kubina Milan , Soviar Jakub
Published: November 2019

The possibilities of expanding the transport infrastructure in cities are considerably limited, as urban areas of the municipalities are built-up. The current infrastructure is no longer sufficient to meet standard transport needs in cities, as there has been a growing trend in recent years for both manufactured and sold vehicles. The reason that vehicles are manufactured is the high demand for the purchase of these vehicles, which clearly reflects the subsequent trend of the traveling public using individual transport modes. In individual chapters, this article evaluates the simultaneous use of intelligent transport systems in the Slovak cities and, at the same time, points out further possibilities of SMART elements implementation in transport, which can ensure more efficient transport processes in agglomerations. Given the circumstances that transport infrastructure is no longer sufficient and the vehicles are stationary, which has adverse effects on arrival time as well as on the environment and the quality of life in the cities, the manuscript deals with this issue in particular.

Authors: Dedík Milan , Gašparík Jozef , Brnjac Nikolina
Published: November 2019

Planning the extent of transport services within a selected territory is a topical issue especially in the context of developing integrated transport systems. The objective of this research study is to design a sustainable system of public passenger transport that would be an alternative to expanding individual transport. The implementation of a quality and efficient transport service is a relatively complex process, since, currently, there are no generally applicable principles for its design. This manuscript presents general results of research aimed at solving the problem of transport service within a selected territory issue with a focus on rail transport as an efficient transport system representing a backbone of a transport system. The subject of the investigation is to compile a set of factors affecting the design of the transport concept. The output of the manuscript consists in a proposal of a generally applicable procedure including a calculation of transport potential and characteristics of the inputs. Subsequently, based on the resulting values, it will be possible to determine the extent of the transport services provided by rail transport in any territory, which will contribute to a more efficient and high quality theoretical graph of train running.

Three-Dimensional Mapping in Underwater Environment
Authors: Nunes Alexandra Pereira , Matos Aníbal
Published: November 2019

Autonomous underwater vehicles are applied in diverse fields, namely in tasks that are risky for human beings to perform, as optical inspection for the purpose of structures quality control. Optical sensors are more appealing cost and they supply a larger quantity of data. Lasers can be used to reconstruct structures in three dimensions, along with cameras, which create a faithful representation of the environment. However, in this context a visual approach was used and the paper presents a method that can put together the three-dimensional information that has been harvested over time, combining also RGB information for surface reconstruction. The map construction follows the motion estimated by a odometry method previously selected from the literature. Experiments conducted using real scenario show that the proposed solution is able to provide a reliable map for objects and even the seafloor.
Review of Research Studies on Biomechanics of Swallowing and Dysphagia
Authors: Almeida Joana Lopes , Jorge Renato Natal
Published: November 2019

Dysphagia is a prevalent condition characterised by the dysfunction/ incoordination of the anatomical structures involved in the swallowing biomechanics.
Dysphagia can have serious clinical consequences such as pneumonia, malnutrition, dehydration and even death. It implies a high negative impact on patients quality of life and may also represent increased financial costs in order to treat associated complications.
It is essential to correctly identify and evaluate patients with this problem. However, the gold standard diagnostic exams present risk of aspiration, they are uncomfortable and invasive, and still present other inherent disadvantages/risks related with the technique itself.
The simulation area may contribute to a more detailed knowledge of the swallowing biomechanics and, when applied to pathologic scenarios (i.e. dysphagia), to identify higher risk patients and manage the treatment in a more adequate and specific way. It will also seems to be able to reduce the use of invasive techniques, excessive radiation and associated economical costs.
The aim of this paper is to review the existing research studies on biomechanical mechanisms of swallowing and dysphagia.
Computer simulation seems to be a solution to better understand these mechanisms and even to reduce clinical disadvantages when compared with the available diagnostic methods used with these patients.
Проблема исламизации Поволжья в трудах Ш. Марджани
Authors: Akhunov Azat
Published: November 2019

Among the 19th century Tatar historians Shihabaddin Mardjani (1818-1889) can be named as a pioneer of the historical science in the European sense. More than 30 works devoted to various subjects of Islamic theology belong to his pen. There are historical ones among his works. Sh. Mardjani’s contribution to human sciences was so significant that his works were recognized even during the Soviet era. While the rest of Tatar pre-revolutionary period (until 1917) legacies were under the ban, Mardjani was presented as a historian without mentioning his achievements in Islamic sciences. In our research we are examining the topic of Islamization of the Volga area in Mardjani’s works. As it is known, the official date of adoption of Islam by Tatar ancestors, i.e. Bulgharians, was in year 922 according to Christian calendar. However, some Tatar historians of 18th-19th centuries (e.g. Hisamaddin Muslimi, Tajaddin Yalchigul) argued that Islam has already been practiced in the Volga region in the first centuries of Islam, while the first missionaries were the Companions of the Prophet Muhammad. Shihabaddin Mardjani criticized them for using unreliable information and sources in their works. According to Mardjani the Islamization of the Volga region happened at the same time as Arabs entered Spain at the beginning of 8th century, while in Bulghar Islam appeared in the 8th-9th centuries. In Mardjani’s opinion, the final acceptance and strengthening of Islam in the region happened during Uzbek Khan reign over the Golden Horde (1313-1342).
Percolação de diesel e água em solo areno siltoso não saturado: uma abordagem experimental
Authors: De Cássia Viana Cerqueira Rita , De Fátima Carvalho Miriam , Pereira de Sousa Riseuda , Lemos Machado Sandro , Brandão de Oliveira Iara
Published: November 2019

Ensaios de fluxo bidimensional de água e de diesel em solo SM, compactado com w=5% e  rd=1,62 g.cm-3 foram executados num canal de fluxo monitorado por tensiometria e análise visual. A migração dos fluidos aconteceu uniformemente na vertical e horizontal com espalhamento simétrico das frentes infiltrantes. A razão entre o tempo de chegada das frentes do diesel e da água à franja capilar (td/tw) foi de 2,3, compatível com a razão (ρ/μ/σ) que foi de 2,16. O comportamento das isócronas da água e do diesel foram explicadas pelo efeito conjunto da gravidade e do atrito na descida dos líquidos, representado pela mobilidade (ρ/μ), e o espalhamento lateral pelo efeito da capilaridade, comandada pela tensão superficial (σ). O uso de modelos unidimensionais para simular o avanço da frente bidimensional conduziu à um atraso no tempo de chegada da frente quando se aplica a equação de Brutsaert (1977), enquanto a equação de Philip (1969) proporcionou um elevado adiantamento. O modelo de Green Ampt (1911) conduz à resultados próximos do experimental, mas o de Philip (1969) corrigindo o espalhamento lateral, apresenta melhor aderência aos dados experimentais, com erro de cerca de 10% (retardo para o diesel e avanço para água).

Published: November 2019

Background: Rheumatoid arthritis (RA) is an autoimmune disorder that affects human joints. The disease also can destroy others body systems, including skin, eyes, lungs, blood vessels, and heart. The aim of the current study was to investigate the effectiveness of RA concerning disease activity and the rate of remission, quality of life, and employment as measured by the disease activity score (DAS 28).
Methodology: This cross-sectional study was conducted during the period from October to November 2018. Two RA patient cohorts were created based on the physician-reported DAS28; adequately controlled (DAS28 ≤ 3.2) and inadequately controlled (DAS28 >3.2). We used descriptive statistics to compare the two groups. Statistical analysis was performed using the Statistical Package for Social Sciences (SPSS) software (version. 22). A p-value of ≤0.05 was considered statistically significant.
Results: A quarter (24.5%) of the inadequately controlled cohort were currently in remission less than 70% of those with adequately controlled RA. Also, 31% of the inadequately controlled group had mild RA which was less than those with adequately controlled RA (83.3%; p = 0.001) and fewer patients were found to be with stable disease status (38% vs 65%; p = 0.001). Patients in the inadequately controlled cohort had a lower quality of life, employment (0.49 vs 0.72; p = 0.001), and had higher rates of work impairment(37 vs 18.4; p = 0.04).
Conclusion: Inadequately controlled RA patients (DAS28 > 3.2) were in less remission than those with inadequately controlled RA (DAS28 ≤ 3.2) and there were fewer patients with stable disease status. Patients in the inadequately controlled group had a lower quality of life and employment compared to the adequately controlled cohort who had higher rates of work impairment.

Published: November 2019

Aim: Palmitate is one of the most abundant fatty acid in both liver of healthy individuals and in patients with non-alcoholic fatty liver disease. Palmitate-induced steatosis in HepG2 cells is an in vitro non-alcoholic fatty liver disease model to investigate acute harmful effects of fat overaccumulation in the liver. Non-alcoholic fatty liver disease is strongly associated with atherosclerosis. Paraoxonase-1 and paraoxonase-3 are anti-atherosclerotic enzymes which are bound to high density lipoprotein in circulation and they are primarily synthesized by liver. There is no study that investigated the effect of palmitate-induced steatosis on paraoxonase-1 and paraoxonase-3 enzymes. The aim of present study was to investigate the effect of palmitate-induced steatosis on paraoxonase-1 and paraoxonase-3 enzymes in HepG2 cells. Methods: To induce steatosis, cells were incubated with 0.4, 0.7 and 1 mM palmitate for 24 hours. Cell viability was evaluated by 3-(4,5-Dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide assay. Cells were stained with oil red O and triglyceride levels were measured. Paraoxonase-1 and paraoxonase-3 protein levels were measured by western blotting, their mRNA expression were measured by quantitative PCR and arylesterase activity was measured spectrophotometrically. Results: All palmitate concentrations caused a significant increase on paraoxonase-1 mRNA levels. Palmitate concentrations did not cause a significant change on paraoxonase-1 and paraoxonase-3 protein levels, paraoxonase-3 mRNA levels and arylesterase activities. Conclusion: Our study showed that palmitate-induced steatosis up-regulates paraoxonase-1 mRNA, has no effect on paraoxonase-1 and paraoxonase-3 protein levels, paraoxonase-3 mRNA and arylesterase activity in HepG2 cells.

Published: November 2019

One of the sectors most influenced by digitalization is tourism and the use of the Internet for brand building is an increasingly common custom, especially by taking advantage of the benefits Social Media has to offer to related businesses. In the given context, the aim of this article is to analyze the role of Social Media and User-Generated-Content in Millennial consumers’ travel behavior, to investigate how these influence people’s decisions to visit specific tourist destination and how various tourism indicators fluctuated in the last two decades, in order to have a better understanding of the current tourism trends. The primary method used is an online questionnaire, along with documentary analysis, statistical analysis, and personal observation. The article starts with a comprehensive literature review that addresses key themes such as tourists decision-making behavior, motivation of travel, or user-generated content. The relationship between Social Media and the desire to travel, but also the manner in which Social Media is used throughout the whole holiday decision-making process are examined. Hence, the paper investigates the impact of Social Media on the travel choices of Romanian Millennial residents, also known as Generation Y, the largest cohort of Internet users, often called digital natives, as they are the first generation born in the Information Age and for whom travel is a way of life. The paper also draws attention to the ways in which travel and tourism businesses could reshape and customize their current marketing strategies in order to gain competitive advantage in the industry.
Not Only Economics: The Political Economy of Euro Adoption in Romania
Authors: Şimandan Radu , Leuştean Beatrice , Dobrescu Răzvan
Published: November 2019

The multifaceted interplay of economic and political factors in the process of euro adoption suggests the opportunity to take a political economy perspective on this complex issue. In this sense, a number of key political-economy related issues can be distilled in relation to the process of euro adoption, which will structure the following analysis. What are the key national winners and losers of this possible event? What role has interest groups pressure played in this process? Under what circumstances may bureaucracies such as the central bank body of experts act as a deterrent for the political end that is the single currency adoption? How are internationally exposed companies expected to behave and to promote their interests in relation to this event? What is the relative importance of the internal politics dynamic for euro adoption? We rely on process tracing to approach these questions for the Romanian case. Policy documents, newspaper articles, academic articles, economic indicators, and elite interviews are used to create an analytical narrative based both on a one-point-in-time description of the situation and on a timeline that lists the sequence of some relevant events. We argue that a specific combination of economic and political factors led to the failed euro adoption in Romania.

2019 год насыщен памятными датами, связанными с жизнью и научной деятельностью Ф. Я. Кона, исследователя истории и культуры тувинского и других народов Восточной и Южной Сибири. В числе этих юбилейных дат — 85-летие выхода его собрания сочинений «За пятьдесят лет» (1934), третий том которого составляет «Экспедиция в Сойотию». Книга была написана по материалам Засаянской экспедиции (в Туве), которая проводилась по поручению Восточно-Сибирского отдела Императорского Русского географического общества (ВСОИРГО). Исследователи неизменно высоко оценивают результаты экспедиции Ф. Я. Кона, не уделяя при этом особого внимания ее хронологии.Ее хронология восстанавливается по материалам протоколов заседаний и отчетов ВСОИРГО, а также писем и отчетов Ф. Я. Кона. Подготовительный этап экспедиции, начавшийся весной 1901 г., затянулся до следующего года. Разработанная в этот период программа экспедиции была опубликована лишь в начале 1904 г. Второй этап экспедиции продолжался в течение двух лет. Последовательность событий 1903 г. выстраивается по периодам в соответствии с маршрутами второго года экспедиции, начавшейся 27 марта и завершившейся 4 августа, и фазами стационарной работы.Хронологические рамки первого этапа исследования разнятся в рассмотренных источниках. Также, помимо представленного Ф. Я. Коном взгляда на решение вопроса, вынудившего его прервать экспедицию в марте 1902 г., показаны действия, предпринятые Распорядительным комитетом ВСОИРГО. Уточняется дата фактической публикации информации об экспедиции Ф. Я. Кона в Русском антропологическом журнале.Хронология экспедиции позволяет уточнить ход проведенных Ф. Я. Коном экспедиционных исследований. Собранные им материалы в основном этнографического характера. Вместе с тем они представляют несомненную ценность для лингвистов, в первую очередь топонимистов и диалектологов. Авторы статьи полагают, что в дневнике Засаянской экспедиции обнаружатся лексические материалы, которые в перспективе станут предметом научного исследования.

Статья вводит в научный оборот тексты двух рукописных стихотворных произведений, вошедших в содержание ойратского литературного сборника «Maniyin tayilbuur orošibо» (XVIII в.), написанного на «тодо бичиг»(«ясном письме»), из фонда Национального музея им. Алдан-Маадыр Республики Тыва.Исследуемый рукописный сборник относится к популярной литературе назидательных разъяснений (тайилбур) и поучений (сургалов), бытовавших в буддийской литературе монгольских народов, в том числе и ойратов. Так как большая часть рукописного фонда музея была сформирована из источников, поступивших из буддийских монастырей, расположенных на территории Тывы, следует предположить, что наличие этих текстов было необходимо не столько для религиозно-обрядовой практики, сколько для популяризации и усвоения философских догматов буддизма у тувинцев.Выполнены транслитерация, переводы на современный калмыцкий и русский языки текста рукописи; дан анализ каждого произведения, входящего в рукописный сборник; выявлены особенности описываемого сборника: тематический принцип подбора материала, афористичность изложения, простота объяснения сложных философских терминов.

Background:

Perioperative hypothermia is linked to multiple postoperative complications including increased surgical bleeding, surgical site infection, myocardial events, and increased length of hospital stay. The purpose of this study is to determine the effects of forced-air warming blanket position, above the shoulders versus under the trunk/legs, on intraoperative core body temperature and perioperative complications in elective lumbar spine surgery.

Methods:

After IRB approval, patients were enrolled in a consecutive fashion and randomized to either upper body (Group I) or lower body (Group II) groups. Primary outcomes were intraoperative body temperature, incidence of hypothermia, postoperative complications, and infection. Secondary outcomes included blood loss, operative time, and length of stay.

Results:

Seventy-four patients were included (Group I, 38; Group II, 36, mean age 60.7 years, 54% of male). Average patient follow-up was 69 ± 33.6 days in Group I and 67 ± 34.6 days in Group II. Average intraoperative body temperature was 35.7 in Group I and 35.8 in Group II (P = 0.27). Incidence of critical hypothermia (T < 35°C) was 18.4% and 11.1% in Groups I and II, respectively (P = 0.52). Incidence of mild hypothermia (T: 35°C–36°C) was 34.2% and 30.56% in Groups I and II, respectively (P = 0.81). Separately, pooled analysis comparing average body temperature and incidence infection demonstrated a relationship between mild hypothermia and infection (P = 0.03).

Conclusion:

Compared to using a lower body Bair Hugger under the patient, using standard upper body Bair Hugger may be associated with increased surgical site infection. Given equivalent body warming, we recommend using the lower body Bair Hugger to avoid infection.
Langerhans cell histiocytosis of the orbit and frontal sinus of the adult woman: A first case report in Poland
Authors: Kostyra Kacper , Kostkiewicz Bogusław
Published: November 2019

Background:

Langerhans cell histiocytosis (LCH) is a term describing a clonal proliferation of pathologic Langerhans cells (histiocytes), which may manifest as unisystem (unifocal or multifocal) or multisystem disease. LCH is a rare cause of the orbital tumor with the predilection to its lateral wall which is particularly common in children.

Case Description:

We report an unusual case of a 33-year-old woman, 6 months after childbirth, who presented with the edema of the right orbit and upper eyelid with headaches. On physical examination, the patient had a right superior and lateral swelling of the eyelid and the orbit and right enophthalmos, without blurred vision. Magnetic resonance imaging showed well-defined, expansile, intensely homogeneously enhancing mass lesion in the right superolateral orbital rim with the destruction of the upper wall of the orbit, growing into the frontal sinus and frontal part of the cranium with the bold of the dura mater in this region. Radical excision of the tumor was achieved through a right fronto-temporo-orbito-zygomatic craniotomy. Histopathological examination had confirmed the diagnosis of the LCH. The patient was discharged home with a modified Rankin Scale score of 0.

Conclusion:

The main purpose of this case report is that LCH should be considered as one of the possible causes of quickly appearing tumor of the orbit in adults.
Bridging the Physics and Chemistry of Graphene(s): From Hückel’s Aromaticity to Dirac’s Cones and Topological Insulators
Authors: Zdetsis Aristides
Published: November 2019

By bridging graphene and benzene through a well-defined sequence of polycyclic aromatic hydrocarbons and their inherent shell structure, it is shown that graphene is actually a coherent arrangement of interwoven benzene molecules, coordinated by aromaticity, shell structure, and topology, all interrelated and microscopically realized through dynamical flipping of the atomic pz-orbitals, playing the role of pseudospin or “qubits”. This renders graphene resonance structure, “resonating” between two complementary aromaticity patterns, involving 2k, k→∞ kekulé type of resonances resulting in “robust electronic coherence”, with dual “molecular-crystalline” nature, and two valence-conduction bands of opposite parity, driven by inversion symmetry competition, which is essentially a “molecule-versus-crystal” competition, in accord with topological-insulator and many-body theory. The “average picture” converges to the usual band structure with two aromatic π-electrons per ring, and the fingerprints of inversion-competition at the D3h-symmetric Dirac points, which for rectangular nanographene(s) appear as gapless topological edge states without real spin-polarization, contrary to opposite claims.

Posttranslational modifications (PTMs) are important in the regulation of protein function, trafficking, localization, and marking for degradation. Here, we describe development of peptide activity-based probes for the discovery of proteins that recognize novel acyl-based PTMs on lysine residues in the proteome. The probes contain surrogates of epsilon-N-acyllysine by introduction of either hydrazide or thioamide functionalities to circumvent hydrolysis of the modification during the experiments. In addition to the modified PTMs, the developed chemotypes were analyzed with respect to effect of peptide sequence. The photo cross-linking conditions and subsequent functionalization of the covalent adducts were systematically optimized by applying fluorophore labeling and gel electrophoresis (in-gel fluorescence measurements). Finally, selected probes, containing the epsilon-N-glutaryllysine and epsilon-N-myristoyllysine analogues, were successfully applied to enrichment of native, endogenous proteins from cell lysate, recapitulating the expected interactions of SIRT5 and SIRT2, respectively. Interestingly, the latter mentioned was able to pull down two different splice variants of SIRT2, which has not been achieved with a covalent probe before. Based on this elaborate proof-of-concept study, we expect that the technology will have broad future applications for pairing of novel PTMs with the proteins that target them in the cell.

Light-emitting diodes (LEDs) are an efficient source of lighting, with many commercial applications like general illumination, camera flashes, phone or laptop displays, and TV screens. However, they present some limitations, including low-quality colour rendition, and the use of expensive/toxic rare-earth elements. Therefore there is an urgent need for the development of improved luminescent materials free of rare earths. Luminescent metal-organic framework (LMOF) materials have emerged as promising candidates for photonics devices. Most of the MOF-LEDs reported hitherto are of the down-converter type, where UV or blue LED are coated with LMOFs, however there is very limited progress in the development of LED using LMOFs as the electroluminescent layer. Herein, we report a novel Guest@MOF composite synthesized by encapsulating a semiconducting Gaq3 metal complex [gallium(III) tris(8-hydroxyquinolinato)], into the ZIF-8 pore [Zn (2-methylimidazolate)2], yielding a green-yellowish luminescent material exhibiting a relatively high quantum yield (15%) upon photo-excitation. Subsequently, we show a down-converter LED made from 405-nm violet LED coated with Gaq3@ZIF-8, yielding a white MOF-LED. Then we demonstrate the use of Gaq3@ZIF-8 as an electroluminescent layer in a hybrid-LED, achieving an orange-yellowish emitting device. This work reveals the potential of LMOFs for next-generation LED technology, by exploiting the Guest@MOF concept to enable electroluminescent applications.
