Abstract
ZrS2 amibipolar MISFETs are obtained in operations with both electrons and holes. A layered polycrystalline ZrS2 thin film was formed by sputtering and sulfur-vapor annealing on a whole surface of a 2.4 cm × 2.4 cm SiO2/Si substrate. The ZrS2 FETs have Al2O3 gate insulator and TiN film for both the top-gate electrode and Schottky-barrier contact, which show symmetrical I

gs curves with a V
off of 0.4 V contributed by the TiN film with midgap work function to the sputtered ZrS2 film. Notably, ambipolar FET operations because of both electrons and holes were successfully observed with an on/off current ratio of 250. This is an important step to realize n/p-type unipolar ZrS2 FETs.

Abstract
Compact and radiation-tolerant radiation dosimeter without bias voltage application using solar cells such as CdTe was proposed for severe radiation environment near a nuclear reactor pressure vessel. In this work, γ-ray tolerance and γ-ray detection characteristics of CdTe solar cells were investigated. It was found that the CdTe solar cell has sufficient tolerance against γ-ray exposure up to 3 MGy. It was demonstrated that γ-ray induced current density linearly increased with increasing γ-ray intensity in the range up to approximately 1.5 kGy h−1. This result indicates that high dose-rate radiation detection can be performed using solar cells without voltage application. In addition, γ-ray sensitivity was successfully improved by a stack of CdTe solar cells with parallel connections. Furthermore, γ rays can be detected with high responsivity and small noise even under a high flux neutron environment.

Published: December 2020

Abstract
Ferroelectric gate transistor (FGT) with yttrium doped hafnium-zirconium dioxide (Y-HZO) gate insulator and oxide channel with various thicknesses of In2O3 and ITO were fabricated by chemical solution deposition. First, ferroelectric properties of Y-HZO in the metal-ferroelectric-semiconductor structure with 5–22 nm thick In2O3 and 6–24 nm thick ITO, have been confirmed by polarization–voltage and capacitance–voltage (C–V) characteristics. The C–V curves showed clear butterfly loops showing the depletion of In2O3 and ITO layer. Secondly, the device performance of FGTs has been evaluated with various thicknesses of In2O3 and ITO channel layer. The fabricated FGTs exhibited typical n-channel transistor operation with a counterclockwise hysteresis loop due to the ferroelectric nature of the Y-HZO-gate insulator. It was found that FGT shows a low subthreshold voltage swing, high on/off drain current ratio of 106, large on current, and memory window.
Ion conductive character of low-yttria-content yttria-stabilized zirconia at low temperature
Authors: Nishimura Tomonori , Kojima Toshiya , Nagashio Kosuke , Niwa Masaaki 
Published: December 2020

Abstract
In this work, we discuss ion conductive character of low-Y2O3-content yttria-stabilized zirconia (YSZ) crystallized into high-symmetric phase (cubic and/or tetragonal phases) at relatively low temperature. Low-Y2O3-content YSZ was certainly stabilized into high-symmetric phase by extreme thinning down to around 10 nm. We analyzed the impedance response from ultra-thin YSZ films in metal/insulator/metal (MIM) capacitor measured in the temperature range of 30 °C–440 °C. It is expected that a characteristic kink on Nyquist-diagram is correlated to the conductivity of inner grain of the YSZ. The activation energy for ion conduction is monotonically reduced with decreasing Y2O3 content, whereas the conductivity still exhibits the highest value at certain Y2O3 content.

Reduction of order of device Hamiltonian with adaptive moment estimation
Authors: Okada Jo , Hashimoto Futo , Mori Nobuya 
Published: December 2020

Abstract
We propose an equivalent model of simple form suitable for using in a computer program. The model reduces the order of device Hamiltonian and reproduces a narrow transport window of a target band-structure calculated by an atomistic model. We implemented the model with the adaptive moment estimation and the automatic differentiation technique by using an end-to-end open-source platform for machine learning. We tested the equivalent model on semiconducting nanoribbon and nanowire structures, and confirmed that it correctly reproduces not only the band-structures but also the ballistic transmission functions calculated by the non-equilibrium Green's function method.

Abstract
The semiconductor photocathode with AlGaAs/GaAs superlattice structures, which is a highly durable electron beam source with low energy dispersion, were grown by molecular beam epitaxy. The sample showed a step-like quantum efficiency spectrum of photoelectron emission, indicating its applicability to photocathodes. The optimization of room temperature photoluminescence provides the improvement of the photocathode quantum efficiency up to 0.5%, promising for its further improvement and realistic applications.
Membangun Kerukunan Antarumat Beragama dan Implikasinya bagi Misi Kristen

Indonesia is a pluralistic nation because it consists of various races, languages, cultures, and religions. Diversity has the potential for horizontal conflict in society. Jesus commanded that Christians manifest love for others as well as for themselves. Sincere love will create harmony and harmony with others regardless of the differences in it. This research uses a descriptive qualitative method through exploring literature related to the topic and using parallel biblical texts that describe how believers carry out their call to live in harmony and at the same time carry out a Christian mission to save those who do not believe in Christ. From this research, it is concluded that the Christian mission is the application of the love of Christ. Love is the basis in society to foster tolerance and mutual respect for the rights of everyone, including belief. This reality must change the paradigm and practice of modern Christian mission. Christian mission must stick to the Bible which affirms that faith in Christ is an absolute requirement of salvation. Therefore, there is no reason for the believer or the church not to carry out this missionary command by maintaining religious harmony so that it can be a blessing for those who do not know Christ.Indonesia adalah bangsa yang majemuk karena terdiri dari berbagai suku, bahasa, budaya dan agama. Kemajemukan memiliki potensi konflik horisontal di masyarakat. Yesus memerintahkan agar orang Kristen mewujudkan kasih kepada sesama seperti kepada diri sendiri. Kasih yang tulus akan menciptakan kerukunan dan keharmonisan dengan sesama tanpa memandang perbedaan yang ada di dalamnya. Penelitian ini menggunakan metode kualitatif deskriptif melalui menggali literatur yang berkaitan dengan topik dan menggunakan teks-teks paralel Alkitab yang mendeskripsikan bagaimana orang percaya menjalankan panggilan untuk hidup rukun sekaligus mengemban misi Kristen untuk menyelamatkan mereka yang belum percaya pada Kristus. Melalui penelitian ini disimpulkan bahwa misi Kristen adalah penerapan dari kasih Kristus. Kasih itu menjadi dasar dalam bermasyarakat untuk menumbuhkembangkan sikap toleransi dan saling menghormati hak-hak setiap orang termasuk berkeyakinan. Realitas ini harus mengubah paradigma dan praktik dari misi Kristen modern. Misi Kristen harus tetap berpegang teguh pada Alkitab yang menegaskan bahwa iman dalam Kristus sebagai persyaratan mutlak keselamatan. Tetapi tidak ada alasan bagi orang percaya atau gereja untuk tidak menjalankan perintah misioner tersebut dengan tetap menjaga kerukunan beragama agar dapat menjadi berkat bagi orang yang belum mengenal Kristus.

Published: December 2020

AbstractAndersen–Tawil syndrome (ATS) is a rare potassium channelopathy causing periodic paralysis, cardiac arrhythmias, and dysmorphic features. A detailed analysis of the face could facilitate diagnosis of ATS, as approximately 30% of patients do not show variants in KCNJ2 gene, and diagnosis is established by clinical findings. We aimed to characterize the face in ATS through a quantitative approach, as facial anomalies may be unnoticed on visual inspection. Facial images of 12 subjects with genetically confirmed ATS (six males, six females, age 5–67 years) were acquired through stereophotogrammetry. Using 38 soft‐tissue landmarks, linear distances, angles, and ratios were calculated and expressed as z‐score values, with reference to 477 healthy subjects matched for sex and age. All patients showed decreased lower facial height with shortening of philtrum (mean z‐score ± SD: −1.5 ± 0.9), smaller mid and lower facial depths (−1.9 ± 0.7; −2.3 ± 0.9), short palpebral fissures (right −1.2 ± 0.4; left −1.6 ± 0.6), smaller mandibular ramus length (−2.1 ± 0.4), and increased nasal width/length ratio (1.4 ± 0.5) with smaller nostril axis length (right −1.8 ± 0.8, left −1.6 ± 0.7). Hypertelorism and low‐set ears were detected in two‐thirds of patients. The study quantified facial dysmorphysm in ATS, extending information about known features, and detecting unrecorded philtrum and nostril characteristics, which may be distinctive traits of the disorder.

Published: December 2020

AbstractOcular Genetics at Wills Eye Hospital sees a wide range of rare disorders for accurate diagnosis. To demonstrate how focused consultation and genetic testing results in precise diagnoses, we investigated false diagnosis rates for patients referred with a diagnosis of Stargardt disease. This is a retrospective review of patients over a 3 year period referred to our Ocular Genetics clinic for possible Stargardt disease, or already holding a diagnosis of Stargardt disease. Results of diagnostic and genetic testing were compared to standard definition of Stargardt. Of 40 patients, 14 (35%) had been misdiagnosed. Four had non‐Stargardt phenotype of which three had ABCA4 pathogenic variants with phenotypes inconsistent with Stargardt disease. Two of those with pathogenic ABCA4 variants were related. Nine had pathogenic variants in other different genes with overlapping features of Stargardt disease. One had Thioridazine maculopathy. Our study highlights the essential role of the subspecialty field of ocular genetics in obtaining accurate diagnoses for the delivery of correct counseling and interventional trial eligibility assessment.

Published: December 2020

AbstractA core–shell microcapsule latent epoxy curing agent (2‐PhIm‐PS) is obtained by solvent evaporation method with 2‐phenyl imidazole (2‐PhIm) as the core material and polystyrene (PS) as the wall material. The microcapsule parameters, morphology, structure, curing behavior, and the mechanic properties of cured epoxy resin with this microcapsule latent curing agent were characterized through comparing with 2‐PhIm. The particle size distribution of the microcapsule is narrow, the average particle size is about 10.56 μm, and the core material content is 23%. The prepared 2‐PhIm‐PS microcapsule curing agent has excellent latent curing properties. It can completely cure epoxy resin E‐51 within 10 min at 130°C, and its latent period can be more than 40 days at room temperature. In addition, the curing kinetics of one‐component epoxy resin curing system (E‐51/2‐PhIm‐PS) composed of 2‐PhIm‐PS microcapsules and epoxy resin E‐51 is also studied by using Kissinger equation, Flynn–Wall–Ozawa and Crane formula. The results provide an outline for the evaluation on the applicability of the microcapsule curing agent of 2‐PhIm‐PS for epoxy resin.
FRET‐MC: A fluorescence melting competition assay for studying G4 structures in vitro
Authors: Luo Yu , Granzhan Anton , Verga Daniela , Mergny Jean‐Louis 
Published: December 2020

AbstractG‐quadruplexes (G4) play crucial roles in biology, analytical chemistry and nanotechnology. The stability of G4 structures is impacted by the number of G‐quartets, the length and positions of loops, flanking motifs, as well as additional structural elements such as bulges, capping base pairs, or triads. Algorithms such as G4Hunter or Quadparser may predict if a given sequence is G4‐prone by calculating a quadruplex propensity score; however, experimental validation is still required. We previously demonstrated that this validation is not always straightforward, and that a combination of techniques is often required to unambiguously establish whether a sequence forms a G‐quadruplex or not. In this article, we adapted the well‐known FRET‐melting assay to characterize G4 in batch, where the sequence to be tested is added, as an unlabeled competitor, to a system composed of a dual‐labeled probe (F21T) and a specific quadruplex ligand. PhenDC3 was preferred over TMPyP4 because of its better selectivity for G‐quadruplexes. In this so‐called FRET‐MC (melting competition) assay, G4‐forming competitors lead to a marked decrease of the ligand‐induced stabilization effect (∆Tm), while non‐specific competitors (e.g., single‐ or double‐stranded sequences) have little effect. Sixty‐five known sequences with different typical secondary structures were used to validate the assay, which was subsequently employed to assess eight novel sequences that were not previously characterized.

AbstractBackground and objectivesThe presence of endocrine disruptors in food is creating concern, and consequently, efficient methods for their identification are needed. In vitro bioassays have been developed to study endocrine properties of pure chemicals as well as mixtures. Because of their relative ease of execution and low cost, application of such techniques to whole foods is tempting. This raises a number of technical challenges. To address them, a study was commissioned in a contract laboratory offering in vitro estrogenicity testing of food products.FindingsFour different commercial and regulatory compliant cereal products were sent in blinded triplicates. Some samples were reported to be active by the laboratory. However, the results were not reproducible and very close to the 0% measurable activity. Furthermore, a statistical analysis of the raw data indicated an absence of activity. This was surprising since these products were expected to naturally contain estrogenic compounds such as the phytoestrogens lignans and flavones. However, phytoestrogens in cereals are known to occur mainly in bound, inactive, forms, suggesting that the sample preparation used in the present study was not suitable to release active estrogenic substances. This hypothesis was supported by preliminary data using a high‐resolution mass spectrometry method which did not detect any significant levels of phytoestrogens in the tested cereal extracts.ConclusionsUsing a yeast‐based method, no estrogenic activity was found in breakfast cereals. However, benchmarking the bioassay data against quality criteria raised the question of the qualification of the sample preparation and bioassay used to adequately address estrogenic activity of whole foods.Significance and noveltyThe quality requirements for testing whole food samples were formally addressed. The application of validated and harmonized methods for both sample preparation and bioassay testing is strongly advocated.
Biodegradation of polyethylene terephthalate microplastics by bacterial communities from activated sludge

Published: December 2020

AbstractThe emerging accumulation of microplastics (MPs) in global waters is of increasing concern and it is posing great health risks to both humans and aquatic species, yet suitable technologies to remove MPs are lacking. The objective of this study was to investigate activated sludge as a source of promising biocatalysts for the removal of MPs in water. Bacterial communities in activated sludge were first screened for their potential to degrade hydrolyzable plastics from polyethylene terephthalate (PET) pre‐treated at 100°C for 1 hour. The consortium grew on a mineral medium with PET MPs as the sole carbon and energy source. To further assess its degrading potential, the consortium was put through a standardized CO2 evolution test at a temperature of 30°C, pH 7‐7.5, reactor residence time 168 days, and PET concentration of 2.63 g/L. The biodegradation extent was further validated through assessment of morphological/structural changes on the PET by means of SEM, DSC, FTIR, and viscometry analyses. Upon incubation, the consortium degraded 17% of PET. The molecular weight remained unchanged, reflecting a degradation via surface erosion. Furthermore, the biodegradation was significantly enhanced at high oxygen flow rates. Two bacterial strains within the consortium were isolated and identified as Bacillus cereus SEHD031MH and Agromyces mediolanus PNP3. Both strains thrived when individually cultured with PET while only B. cereus showed enzymatic activity during a clear‐zone test. The examined bacterial strains possess a promising PET‐degrading activity that can be further investigated and applied to the elimination of MPs water/wastewater through innovative and effective technologies.
