AbstractPolypoidal choroidal vasculopathy (PCV) is a distinctive type of neovascular age-related macular degeneration prevalent in many Asian countries. However, there is still some controversy in how the subtypes of PCV are classified. This post-hoc study redefined the branching vascular network (BVN) and PCV subtypes through retrospective review of indocyanine green angiography (ICGA) and fluorescein angiography images from two observational studies (RENOWNED/REAL). Of the visual outcomes for each angiographic subtype and treatment pattern investigated, BVN was identified in 56.3% of PCV patients. The proportions and features of the re-defined PCV subtypes were 43.8%, 10.4%, and 45.8% for subtype A (without distinctive features of BVN), B (with BVN but no leakage), and C (with BVN and leakage), respectively. Subtype A had better visual outcomes when compared to subtype C. This possibly resulted from a better baseline visual acuity in subtype A. Moreover, combination therapy [photodynamic therapy plus anti-vascular endothelial growth factor (VEGF)] may lead to better visual improvement than mono-anti-VEGF treatment alone. This study provides the prevalence of PCV subtypes in Taiwan and may serve as a reference for PCV treatment strategies in a real-world setting, especially for the combination therapy and patients without distinctive features of BVN.

AbstractThe achievement of ultraclean Ohmic van der Waals (vdW) contacts at metal/transition-metal dichalcogenide (TMDC) interfaces would represent a critical step for the development of high-performance electronic and optoelectronic devices based on two-dimensional (2D) semiconductors. Herein, we report the fabrication of ultraclean vdW contacts between indium (In) and molybdenum disulfide (MoS2) and the clarification of the atomistic origins of its Ohmic-like transport properties. Atomically clean In/MoS2 vdW contacts are achieved by evaporating In with a relatively low thermal energy and subsequently cooling the substrate holder down to ~100 K by liquid nitrogen. We reveal that the high-quality In/MoS2 vdW contacts are characterized by a small interfacial charge transfer and the Ohmic-like transport based on the field-emission mechanism over a wide temperature range from 2.4 to 300 K. Accordingly, the contact resistance reaches ~600 Ω μm and ~1000 Ω μm at cryogenic temperatures for the few-layer and monolayer MoS2 cases, respectively. Density functional calculations show that the formation of large in-gap states due to the hybridization between In and MoS2 conduction band edge states is the microscopic origins of the Ohmic charge injection. We suggest that seeking a mechanism to generate strong density of in-gap states while maintaining the pristine contact geometry with marginal interfacial charge transfer could be a general strategy to simultaneously avoid Fermi-level pinning and minimize contact resistance for 2D vdW materials.

Competition reduces profitability: the case of the Indian life microinsurance industry
Authors: Banerjee Subrato , Savitha Basri 
Published: January 2021

AbstractWe aim to understand the effect of market and firm-level concentration on return on equity in the Indian life microinsurance industry (LMI). This research is one of the first attempts to empirically test structure–performance issues in India. Using data on 14 companies that remained active in the LMI market during 2009–2019, we demonstrate that firms in the Indian LMI market scored better on profitability measures whenever competitive pressures were lower. We calculate Herfindahl–Hirschman concentration indexes (HHI), market share and entropy measures and use panel data techniques to find a positive effect of concentration and a negative effect of market share. We conclude that LMI-specialised insurers in India perform better than diversified insurers.
Prosodic transfer across constructions and domains in L2 inflectional morphology
Authors: Austin Gavin , Chang Heejin , Kim Nayoung , Daly Eoin 
Published: January 2021

Abstract
Second language (L2) learners are known to have difficulty producing inflection in obligatory contexts reliably. According
to the Prosodic Transfer Hypothesis (PTH), the prosodic organisation of L2 inflection is constrained by the inventory of representations
available in the L1. At the same time, this hypothesis does not explicitly limit how freely prosodic representations can be transferred, so
that transfer across constructions within the same domain (e.g., verbal domain: L1 tense → L2 agreement) and across domains (e.g., verbal
domain: L1 tense → nominal domain: L2 plurals) are both possible in principle. The goal of this study was to determine if the current
formulation of the PTH is valid, or must be reined in to exclude transfer across domains in particular. Forty-four Korean learners of
English did a spoken sentence-construction task in which they had to produce subject-verb agreement and regular plural inflection. Bayesian
hierarchical regression was used to analyse the results. By examining asymmetries in the suppliance of short- vs. long-stemmed inflection,
we show that there are no grounds for attaching any stipulations to the PTH along the above lines, as prosodic representations are
transferrable not only across constructions but also across domains.
Le Nouveau conseil de Smil Flaška de Pardubice
Authors: Adde Éloïse 
Published: January 2021

Abstrait
Œuvre didactique qui tient tant du bestiaire, de la satire, du miroir au prince que de l’œuvre d’édification religieuse, le Nouveau conseil fait partie des grands textes de la littérature médiévale de langue tchèque. Rédigé en 1394–1395 par le seigneur Smil Flaška de Pardubice, actif partisan du mouvement de l’Union seigneuriale qui s’était opposé au roi, ce texte a souvent été analysé pour son contenu factuel (historique et politique) comme une critique du gouvernement de Venceslas IV. À travers une lecture anthropologique qui interroge l’utilisation du bestiaire, cet article propose de restituer l’épaisseur du message du Nouveau conseil, sa conception de l’homme et de sa place dans le monde (aspects sociaux) ainsi que dans la perspective de la providence. Plus qu’une satire, l’œuvre nous livre une représentation complexe de l’individu, à la charnière entre monde divin et monde terrestre, les animaux permettant de dire l’humanité dans sa diversité, l’individu dans sa singularité, et la personne dans sa complexité.
On the borders of humanity
Authors: Cipriani Mattia 
Published: January 2021

Abstract
The Liber de natura rerum is a thirteenth-century encyclopedia that reflects the naturalistic interests
of its author, the Dominican friar Thomas of Cantimpré (ca.1200/ 01–ca.1270/ 72). Despite his realistic
focus, Thomas was a man of his time and he introduced elements in his work that may seem bizarre to a modern reader. The purpose of this
article is twofold. Firstly, it analyses how the Friar treats these different elements, whether they were widespread in thirteenth-century
culture (e.g. Amazons, wild men, mermaids, etc.) or discussed for the first time by the Thomas himself (e.g. giants of Vienna, wolf-girl of
Burgundy, etc.). Secondly, the paper highlights some very interesting and new aspects of Thomas’s work that shed light on his way of
thinking and on his encyclopedia.
Mnemonic verses concerning animals and birds in Cambridge University Library, Ms Oo. Vii.48
Authors: Dines Ilya 
Published: January 2021

Abstract
This article is devoted to an essentially unknown fragment containing a collection of thirteenth-century mnemonic verses
about animals and birds. It is a logical continuation of a study I published in 2010 in Reinardus about the entire corpus
of mnemonic verses that appear in medieval Latin bestiaries. As the core of that investigation, I chose a late thirteenth-century English
bestiary of the so-called Second Family (Oxford, Bodleian Library, MS Bodley 533). In that article I suggested that further
research would likely uncover more such examples in non-bestiary manuscripts. This was confirmed in 2018 by a newly discovered fragment in
Cambridge University Library, MS Oo.vii.48, containing the verses present in MS Bodley 533, and additional verses about animals and birds.
Using this fragment, I put forward the idea that there was an established medieval tradition of collecting and keeping organized mnemonic
verses devoted to animals and birds. I argue that finding these verses from bestiaries and other sources together in one fragment sheds
light on the interrelations of bestiaries and other genres.
Tracking the Mysterious Loz in the Secrets of Natural History
Authors: Friedman John Block 
Published: January 2021

Abstract
The loz is a bovid that in medieval folklore was believed to live in Bohemia. It defended itself against hunters by spraying them with boiling and corrosive water stored in a dewlap beneath its neck. First appearing in the learned tradition with Bartholomaeus Anglicus’ De proprietatibus rerum, it then shows up in a richly illustrated geographical and wonders treatise, the Secrets of Natural History (SNH) of about 1380. This work is a Middle French translation of a small portion (on wonders of various regions of the world) of Pierre Bersuire’s exempla collection Reductorium Morale. The only visual representations of the loz are to be found in the SNH. I argue that both in its written and in its visual existence, the loz is the offspring of two different animals, also more or less imaginary, the bonnacon of the Bestiary and the other, the onager, or wild ass, though a very unusual form of that animal.
What are they saying?
Authors: Šorm Martin 
Published: January 2021

Abstract
The study presents the interpretative history of the poem New Council written by the author Smil
Flaška in the 1390s. It argues against accents on its determinative connection with the Czech political history; instead it
promotes interpretation based on research of the ways it documents on representations of piety or the social, ethical, or
environmental imagination of the late 14th and 15th centuries. Concentrating on the manuscript context (three codices from the
latter half of the 15th century) as well as on reception of the poem in the 16th century, the study demonstrates that at the time
the poem was transcribed and read, it functioned not as an exclusive lesson for the upper classes or as criticism of the king, but
as a long-tried-and-tested edutaining text, accessible to recipients from various social groups. The New
Council is a synecdochal representation of the created world, wherein birds and animals compel the reader to
relinquish the misleading categories of allegory, irony or satire and submit to the actual subjective effects of God’s word coming
from non-human mouths. The recipient is invited to enter the space between man and animal, as the animals’ utterances based on religious teaching lead to a transformation of his conscience and perception.
Strong gravity effects of charged Q-clouds and inflating black holes
Authors: Brihaye Yves , Hartmann Betti 
Published: January 2021

AbstractIn this paper, we re-examine chargedQ-clouds around spherically symmetric, static black holes. In particular, we demonstrate that for fixed coupling constants two different branches of charged scalar clouds exist around Schwarzschild black holes. This had not been noticed previously. We find that the new solutions possess a ‛hard wall’ at maximal possible gauge coupling. This wall separates the interior (containing the black hole horizon), in which the scalar field is trapped in the ‛false vacuum’, from the ‛true vacuum’ exterior. When taking back-reaction onto the space-time into account, we find that at maximal possible back-reaction, the black hole solutions corresponding to these two branches either become extremal black holes with diverging scalar field derivative on the horizon or inflating black holes with a second, ‛cosmological’ horizon which—outside this second horizon—correspond to extremal Reissner–Nordström black holes.
Investigating the role of oxygen and related defects in the self-biased and moderate-biased performance of β-Ga2O3 solar-blind photodetectors
Authors: Arora Kanika , Kumar Naveen , Vashishtha Pargam , Gupta Govind , Kumar Mukesh 
Published: January 2021

Abstract
High-performance, low-cost, self-powered deep-ultraviolet photodetectors (DUV-PDs) are essential for military and civil applications. β-Ga2O3 stands alone among all the solar-blind materials in its suitability for use in next-generation DUV-PDs. However, deep traps by oxygen vacancies critically affect the photogenerated carriers, and hence the photodetector’s final efficiency. Notwithstanding, both a lack of and an excess of oxygen in β-Ga2O3 ultimately lead to leakage channels, carrier scattering and sub-bandgap absorption. However, no studies on the impact of extremes of oxygen (oxygen-poor and oxygen-rich) on β-Ga2O3 photodetector efficiency are available in the literature. Therefore, in the present work, we aim to understand the impact of varied oxygen flow rates from 0% to 4% on material properties and photodetector performance. Photoluminescence, time-resolved photoluminescence (TRPL), x-ray photoelectron spectroscopy and the electrical properties of fabricated photodetectors confirmed the critical role of oxygen in β-Ga2O3. TRPL measurements revealed that β-Ga2O3 with 1% oxygen flow had a reported shortest decay time of nearly 50 ps. A very low dark current of 0.9 pA and a maximum photo-to-dark current of >103 were achieved at zero bias for β-Ga2O3 under optimum oxygen flow. The responsivity, external quantum efficiency, detectivity and dark current for a sample at moderate bias fabricated under optimum oxygen flow were found to be 190.08 A W−1, 9.42 × 104%, 1.22 × 1015 Jones and 21 nA, respectively. Hence, the measurements showed that for better device performance and self-powered response, oxygen concentrations that are neither too low nor too high are needed, and the detailed mechanism behind this is discussed. Comparison of the figures of merit with those of other reported devices in both self-powered and high bias mode reveals the far superior performance of the present device.
First-principle investigation of all types of topological nodal lines in a realistic P63/mmc type titanium selenide

Published: January 2021

Abstract
Topological nodal line (TNL) materials with one-dimensional band-crossing points (BCPs) exhibit interesting electronic characteristics and have special applications in electronic devices. Normally, based on the slopes of the crossing bands, the BCPs can be divided into two types, i.e., type I and type II nodal points. Based on the combination of the different types of nodal points, the nodal lines (NLs) can be divided into three categories: (i) type I NL, type II NL, and hybrid NL, these being formed by type I nodal points, type II nodal points, and type I and II nodal points, respectively. Compared with the large number of predicted type I NL materials, there are less type II and hybrid NL materials. In this study, it is predicted that P63/mmc type TiSe metal is a topological material which exhibits all types of NL states. Furthermore, the dynamic stability as well as the effect of spin–orbit coupling on the topological signatures are examined. Also, the nontrivial surface states are shown to provide evidence for the occurrence of the NL states. This novel material can be seen as a good platform to use for further investigations on the three types of NLs and diverse fermions.

Abstract
The LabPET II is a new positron emission tomography technology platform designed to achieve submillimetric spatial resolution imaging using fully pixelated avalanche photodiodes-based detectors and highly integrated parallel front-end processing electronics. The detector was designed as a generic building block to develop devices for preclinical imaging of small to mid-sized animals and for clinical imaging of the human brain. The aim of this work is to assess the physical characteristics and imaging performance of the mouse version of LabPET II scanner following the NEMA NU4-2008 standard and using high resolution phantoms and in vivo imaging applications. A reconstructed spatial resolution of 0.78 mm (0.5 μ
l) is measured close to the center of the radial field of view. With an energy window of 350 650 keV, the system absolute sensitivity is 1.2% and its maximum noise equivalent count rate reaches 61.1 kcps at 117 MBq. Submillimetric spatial resolution is achieved in a hot spot phantom and tiny bone structures were resolved with unprecedented contrast in the mouse. These results provide convincing evidence of the capabilities of the LabPET II technology for biomolecular imaging in preclinical research.

Abstract
In this paper, we designed a low turn-on voltage (V
On) AlGaN/GaN lateral field-effect rectifier (LFER) compatible with p-GaN gate high-electron-mobility transistor (HEMT) technology (PG-LFER). We also established an analytical model on the gated control two-dimensional-electron-gas density (n
S) distributions and V
On to investigate the underlying mechanism. The designed PG-LFER features a p-GaN charge storage layer (CSL) under the anode terminal. Net negative charge density in the p-GaN CSL (σ
p-GaN) is associated with the activated doping concentration of p-GaN CSL (N
p-GaN) and p-GaN CSL thickness (t
p-GaN). V
On of the PG-LFER is significantly lowered due to the low σ
p-GaN caused by reducing the N
p-GaN and t
p-GaN. Meanwhile, the low V
On PG-LFER also preserves recognizable reverse blocking and capacitance characteristics. Verified by the calibrated simulation, the designed PG-LFER shows 70% lower V
On compared with the non-optimized LFER with a high σ
p-GaN. Compatible with p-GaN gate HEMT technology, the designed PG-LFER with improved performance is a promising candidate for power integrated applications.

Abstract
In current years, there is an sudden increase of wireless data Traffic which has resulted in a huge scale dense deployment of small cells, with which the increasing cost of energy has concerned a set of research interest. I present the wireless network which consists of distributed sensor nodes. The function of distributed sensor nodes is to manage the physical condition and to generate the traffic system. Each and every nodes in WSN will sends and receives the packet ensuing in depletion of bandwidth. However, bandwidth sensor nodes are not an productive by saving the energy. Thus, sleep/wake-up scheduling is one of the vital problems in the wireless sensor network. Because, they are fixed and it cannot be recharge again. An energy efficient sleep/wake-up scheduling approach is proposed. The aim of this approach is to save the energy of each nodes and to increase their lifetimes.
