Interfacial Electrostatic‐Interaction‐Enhanced Photomultiplication for Ultrahigh External Quantum Efficiency of Organic Photodiodes

A photomultiplication‐type organic photodiode (PM‐OPD), where an electric double layer (EDL) is strategically embedded, is demonstrated, with an exceptionally high external quantum efficiency (EQE) of 2 210 000%, responsivity of 11 200 A W−1, specific detectivity of 2.11 × 1014 Jones, and gain–bandwidth product of 1.92 × 107 Hz, as well as high reproducibility. A polymer electrolyte, poly(9,9‐bis(3′‐(N,N‐dimethyl)‐N‐ethylammoinium‐propyl‐2,7‐fluorene)‐alt‐2,7‐(9,9‐dioctylfluorene))dibromide is employed as a work‐function‐modifying layer of indium tin oxide (ITO) to construct an EDL‐embedded Schottky junction with p‐type polymer semiconductor, poly(3‐hexylthiophene‐diyl), resulting in not only advantageous tuning of the work function of ITO but also an enhancement of the electron‐trapping efficiency due to electrostatic interaction between exposed cations and trapped electrons within isolated acceptor domains. The effects of the EDL on the energetics of the trapped electron states and thus on the gain generation mechanism are confirmed by numerical simulations based on the drift–diffusion approximation of charge carriers. The feasibility of the fabricated high‐EQE PM‐OPD especially for weak light detection is demonstrated via a pixelated prototype image sensor. It is believed that this new OPD platform opens up the possibility for the ultrahigh‐sensitivity organic image sensors, while maintaining the advantageous properties of organics.

Elucidating the molecular mechanisms of streptococcal M protein-induced autoimmune sequelae

Streptococcus pyogenes infiziert mehr als 600 Millionen Menschen im Jahr. Auser einer Vielfalt von akuten Infektionen, verursacht das Bakterium akutes rheumatisches Fieber (ARF), eine Autoimmunerkrankung, die haufig zur rheumatischen Herzerkrankung fuhrt (RHD). RHD ist ein fuhrendes Gesundheitsproblem in einigen Schwellen- und Entwicklungslandern. M Protein von Streptokokken ist ein Ausloser von ARF. Es verursacht Autoimmunitat durch molekulare Mimikry von Coiled-Coil-Proteinen des Wirts wie Myosin und Laminin. Auserdem tragen einige M proteine, die eine Autoimmunitat gegen Kollagen IV auslosen, das kollagenbindende A/T/E)xYLxx(L/F)N-Motiv. Diese Immunantwort wird auch in Patienten mit ARF beobachtet, ist aber keine Folge molekularer Mimikry. Aufgrund dieser Beobachtungen wird das Motiv “peptide associated with rheumatic fever” (PARF) genannt. Die Rolle der Kollagenbindung als Ausloser der Autoimmunitat gegen Kollagen IV und anderen Wirtsproteinen war bisher nicht ausreichend untersucht. Deshalb wurden in dieser Arbeit verschiedene M proteine auf Bindung von Kollagen I oder IV und Auslosen von Autoimmunantworten gegen diese Kollagene und die Coiled-coil Proteine Myosin oder Laminin getestet. Dies wies zum ersten Mal nach, dass die Induktion der Kollagen-IV-Autoimmunitat PARF-spezifisch ist und folglich nicht durch andere Teile oder Eigenschaften des M Proteins verursacht wird. Weitere Beweise fur die Rolle von PARF als Ausloser fur Autoimmunitat kamen von Experimenten mit einem rekombinanten Protein (PARF tandem), das alle bisher bekannten naturlich vorkommenden PARF-Motive enthielt. In Mausen induzierte PARF tandem Autoimmunitat gegen Kollagen und Myosin. PARF tandem loste im Kanninchen die Produktion opsonisierender Antikorper aus, die gegen PARF-positive M proteine reagierten. Da die Immunisierung mit PARF tandem aber auch Autoimmunitat verursachte, musste eine PARF-basierte Impfstrategie weiterentwickelt werden. Die Entdeckung von Spa als neues kollagenbindendes Protein, das Autoimmunitat gegen Kollagen auslost, erweitert das Spektrum potentieller rheumatogener Faktoren in S. pyogenes. Zum ersten Mal wurde ein Ausloser von Autoimmunitat in einem emm-Typ (emm18) entdeckt, der zu Ausbruchen von ARF gefuhrt hat. Die vorliegende Arbeit weist klar auf eine Rolle von Interaktionen zwischen Wirts- und Mikrobiellen Proteinen in der Entstehung von Autoimmunitat hin und konnte eine neue Facette in der Pathogenese von Autoimmunerkrankungen aufgedeckt haben.
A comparative study of efficacy of dermaroller versus fractional CO2 laser for management of post acne scars

Background: Acne vulgaris is a chronic skin disease caused due to blockage and/or inflammation of pilosebaceous units in which lesions present as non-inflammatory, inflammatory or mixture of both. The inflammatory type, often results in distressing scars for which dermaroller therapy and fractional CO2 laser have shown to be effective treatment modalities. Material and Methods: This is a prospective, descriptive and hospital based study. Total of 140 cases were enrolled in study carried out for 1 year in the Department of Dermatology at tertiary health centre and medical college with subsequent follow up of up to six months. Patients with acne scars under the groupings of a score > 3 points on Global Acne Scarring Classification Scale were enrolled.Results: Out of 140 patients, (70 - dermaroller group, 70 - CO2 laser group) completed treatment and follow-up. Dermaroller therap results indicated that the baseline was 23.43±6.32 and reduced to 13.23±3.65 after the treatment. This difference was found to be statistically highly significant with p value as
Assessment of interspecific hybridization between wild beet Beta vulgaris L. subsp. maritima and cultivated sugar beet under Moroccan conditions

Obtaining a viable and fertile beet hybrid resulting from wild and cultivated sugar beet crosses under Moroccan conditions is challenging. To deal with hybridization, barriers in sugar beet, such as concordance of flowering period between biannual and annual subspecies, flowering aptitude according to vernalization requirement, genotype incompatibility and hybrid sterility, should be overcome. In our study, interspecific hybrids were obtained from crosses between 17 cultivated sugar beet Beta vulgaris subsp. vulgaris and 17 Beta vulgaris subsp. maritima, collected in different regions of Morocco. Twenty-two agro-morphological traits were used for the evaluation of 208 hybrid plants, under greenhouse conditions. CH and WH hybrids were collected on cultivated and wild parents separately. Most of the hybrids behaved as annual plants, of which 83.17% were able to flower and produce seeds without any vernalization requirements. All WH hybrids and 57.06% of CH hybrids were morphologically similar to their wild parent. However, 24% of CH hybrids were phenotypically similar to their cultivated parent. The remaining CH hybrid plants were behaving as intermediate genotypes between both wild and cultivated parents. Our results showed the success of interspecific beet crosses and emphasized the high variability among hybrid genotypes. This is of great importance for sugar beet improvement and breeding programs and interspecific crosses patterns understanding.

Effects of Aerobic Exercise on Oxidant/Antioxidant Status in Obese Boys: A Controlled Trial

It is unclear how aerobic exercise program effects oxidative stress and antioxidant defense parameters in obese children; therefore, our objective is to examine the effects of aerobic exercise on parameters of oxidative stress and antioxidant in obese boys. Our study included 10 obese boys, aged from 13 to 15, and 10 healthy boys as control group. Before and after exercise, 10 ml blood specimens were taken from the obese boys, who exercised 3 days/week for 12 weeks. 10 ml blood specimens were also taken from the health control group. The oxidative stress and antioxidant defense parameter levels in blood samples were measured for both groups. In our study, it was found that control group and obese children after aerobic exercise had significantly higher superoxide dismutase, catalase, glutathione peroxidase and paraoxonase-1 values than those of obese boys before aerobic exercise. On the other hand, it was found that after aerobic exercise, control group and obese children had significantly lower malondialdehyde, nitric oxide and carbonyl values than those of obese boys before aerobic exercise. When these findings are taken into account, it may be suggested that aerobic exercise regulated oxidative stress and improved the state of antioxidant status in obese boys.
A Contraction Theory-Based Tracking Control Design With Friction Identification and Compensation

This article proposes a tracking controller for servomechanisms with a continuous friction model. The parameters of this model are estimated through a proposed two-step offline identification methodology that uses a linear extended state observer (LESO) based on the integral of position measurements, termed as ILESO. In the first step, the viscous and Coulomb coefficients of this friction model are estimated by the ordinary least squares method. The second step employs these estimates to obtain the initial guess for the nonlinear least squares method that identifies all the parameters of the nonlinearly parameterized friction model. Finally, a backstepping controller is designed for reference tracking, which uses the estimated offline friction model and online estimations of the servo position, velocity, and system uncertainty. These online estimations are provided by a modified ILESO, termed as FILESO, that has a similar structure to that of the ILESO but incorporates the identified offline friction model into its dynamics. The convergence and stability of the proposed observer and controller are established using contraction analysis. Experimental results show that the proposed approach exhibits satisfactory performance.
3D modeling of a hyperthermia electromagnetic applicator

This paper describes the model of an electromagnetic field applicator (waveguide) for oncology hyperthermia which achieves a better EM energy focusing. This technology works with non-ionizing radiation and it does not cause side effects to patients. In this paper, the mathematical design of an applicator based on the waveguide equations is described. A dielectric materials study was carried out in order to know which material had the best performance for its use inside the applicator with the intention of reduce its dimensions. Finally, this paper describes the system modeling with the best dielectric material. The model employed RF analysis, in order to generate EM waves in TE-mode, and the bioheat equation, which relates temperature increases in tissue due to EM waves. The modeling results of the system describe the temperature distributions inside the phantom. This applicator can be used in oncological therapy due to its efficiency and its low cost which represent an extra advantage.

Screening of Metal Chloride Anion-based Ionic Liquids for Direct Conversion of Hydrogen Sulfide by COSMO-RS

In order to identify the best possible reaction media for performing H2S conversion, a total number of 300 different ILs from a combination of 20 cations and 15 anions were screened via COSMO-RS model simulations. By COSMO-RS method, thermodynamic and physicochemical properties of 300 ILs such as Henry’s law constants, activity coefficient, selectivity, capacity and performance index are obtained and analyzed. Thus, by comparing the performance of ILs via COSMO-RS, a series of TSILs containing cation of [P66614] with metal chloride anions such as Fe, Ga and Sn were chosen and selected for synthesis based on their performance predicted by COSMO-RS and their economic values. Consequently, the physiochemical properties such as density, viscosity, thermal properties, as well as H2S absorptive oxidation performances in those TSILs will be systematically investigated.
An Organic Transistor-based Electrical Assay for Copper(II) in Water

We herein report an electrical assay for copper(II) (Cu2+) utilizing an organic thin-film transistor (TFT). To endow the metal ion recognition ability, the extended-gate portion in the organic TFT is functionalized by a nitrilotriacetic acid (NTA)-terminated monolayer. As a result, the device responds selectively to Cu2+ in aqueous media. Importantly, the estimated detection limit for Cu2+ (= 96ppb) is much lower than environmental standard value of a copper contaminant in drinking water. Its superior processability and portability in the organic device indicate that the proposed assay could be applied for on-site detection of the Cu2+ ion without large-sized equipment. © The Electrochemical Society of Japan, All rights reserved.
Recirculation zone characteristics research on a sudden expansion swirl burner for DPF regeneration

Based on the autonomously designed sudden expansion swirl burner and combined with the characteristics of diesel particulate filter (DPF) regeneration, fitting geometric parameters and values were determined with the orthogonal experimental design method. And the effects of main geometric parameters such as the sudden expansion ratio, length‐diameter ratio and position of air supply pipe on main evaluation indexes of the recirculation zone characteristics were studied with CFD. Results showed that with the geometry of sudden expansion ratio 2.0 and length‐diameter ratio 2.1 and air supply pipe located in the middle of the combustion chamber, the length of the recirculation zone in the center could be increased greatly; in order to increase the reattachment length, the sudden expansion ratio should be 1.5–2.0 and the length–diameter ratio should be larger and the air supply pipe should be closer to the fuel spray nozzle; and the swirl intensity was mainly depended on the length–diameter ratio, which could be effectively enhanced when the length–diameter ratio ranged from 2.1 to 2.4. It provides beneficial references for the research of complex flow field in sudden expansion swirl burner and porous medium. © 2018 American Institute of Chemical Engineers Environ Prog, 37: 1901–1907, 2018
Quantum thermodynamics at low temperatures

Low temperature phenomena and methods are quantum thermodynamics per se. Modern engineered quantum systems, for instance those used for superconducting quantum information processing and mesoscopic electron transport, provide working media for realizing devices such as quantum heat engines and refrigerators and a testbed for fundamental principles and phenomena in thermodynamics of quantum systems and processes.
ANALYSIS OF DCM INTERLEAVED BOOST CONVERTER FOR PV AC-MODULE APPLICATION

An interleaved boost converter (IBC) has the advantage of the reduced current ripple, and hence minimizing the input filter size. However, conventional IBC was not used in high voltage-gain applications to avoid the extreme duty cycle. In this paper, the performance of the IBC is analysed when employed, in the discontinuous conduction mode (DCM), in a dual-stage photovoltaic (PV) AC-module system. Conventional boost converters models with 2-phase IBC and 3-phase IBC are developed and simulated using the MATLAB/SIMULINK tool in a dual-stage, grid-connected PV AC-module system. The converters were simulated under DCM, and the duty cycle, current ripple, and efficiency were analysed under different solar irradiance levels. To identify the most efficient design/ mode of operation, DCM is considered for the phase currents of the IBC while both the continuous conduction mode (CCM) and the DCM are investigated for the entire input current. The results showed that operating the IBC at DCMof the phase currents whilst keeping the total input current at CCM reduces the input current ripple and improves the efficiency and reliability of the converter.
Spatio-Temporal Patterns of Global Population Exposure Risk of PM2.5 from 2000–2016

A high level of fine particulate matter (PM2.5) has become one of the greatest threats to human health. Based on multi-source remote sensing data, the pollutant population exposure model, accompanied by the Theil–Sen Median and Mann–Kendall methods, was used to analyze the spatio-temporal patterns of global population exposure risk of PM2.5 from 2000 to 2016. The population distribution patterns of high-risk exposure areas have been accurately identified; the variation trend and stability of global population exposure risk of PM2.5 have also been analyzed. According to the results, the average concentration of PM2.5 is correlated with the total population. The average concentration of PM2.5 for countries from high to low are Asia (14.7 μg/m3), Africa (8.1 μg/m3), Europe (8.03 μg/m3), South America (5.69 μg/m3), North America (4.41 μg/m3), and Oceania (1.27 μg/m3). In addition, the global average population exposure risk of PM2.5 is decreasing annually. Specifically, China, India, Southeast Asia, and other regions have higher exposure risks. Less developed mountainous regions, cold regions, deserts and tropical rainforest regions have lower exposure risks. Moreover, Oceania, North America, South America and other regions have relatively stable exposure, whereas areas with relatively unstable exposure risk of PM2.5 are mainly concentrated in Asia, India, and eastern China, followed by Southeast Asia, Europe, and Africa. Furthermore, Asia has the largest population of all the continents, followed by Africa and Europe. Countries with increased populations are mainly distributed in Africa, whereas the countries with a declining population are mainly distributed in Europe. Based on this, it is important to identify the relationship between PM2.5 concentration and population exposure risk to improve human settlements and environmental risk assessment.

The utility of gingival crevicular fluid matrix metalloproteinase-8 provides site-specific diagnostic value for periodontal grading

Introduction Matrix metalloproteinase-8 (MMP-8), and its active form aMMP-8, was identified as a potential biomarker of periodontal tissue destruction. It is present at different concentrations in various oral fluids. Material and methods Gingival crevicular fluid (GCF) samples were collected from periodontal pockets ≥ 6 mm of 24 untreated patients using paper points and clinical parameters were recorded. 12 subjects were diagnosed with periodontitis stage III grade B, and 12 others with periodontitis stage III grade C. After thorough preparations, samples were collected following manufacturers’ instructions and analyzed using a commercially available test system for aMMP-8 evaluation (aMMP-8 Test) and Periotron 8000 together with Quantikine kits for assessment of total MMP-8 concentration (controls). Microbiological evaluation of the same pockets was carried out using real-time polymerase chain reaction. Results Concentrations of both total MMP-8 and aMMP-8 in GCF were higher in the case of periodontitis grade C, compared to periodontitis grade B, but reached statistical significance only in the case of total MMP-8 (77.17 ng/ml and 18.73 ng/ml respectively; p = 0.0104). Positive correlations were found between total MMP-8 and aMMP-8 levels and the prevalence of Fusobacterium nucleatum, mean probing pocket depth of all pockets, % of pockets ≥ 6 mm, as well as probing pocket depth of pocket from which GCF samples were collected. Conclusions GCF concentration levels of both total MMP-8 and aMMP-8 correlated with severity of periodontal destruction, whereas total MMP-8 appeared to be a preferable method for differentiation of periodontal grading. However, the aMMP-8 Test was easier and more convenient to handle.
