Summary
Background
Despite the availability of effective and well-tolerated direct acting antivirals (DAAs) against hepatitis C virus (HCV) infection, a substantial number of HCV patients remain untreated. Novel strategies targeting HCV patients with poor adherence are urgently needed to enable HCV elimination.

Methods
We implemented a physician-operated HCV hotline (HCV-Phone) that was promoted within the patient community and referral networks. Previously diagnosed HCV patients were contacted via the HCV-Phone and offered low-barrier access to DAA therapy. Patients/referring physicians could directly call or send messages to the HCV-Phone. The HCV-Phone related and unrelated visits as well as DAA treatment initiations throughout 2019 were documented. Patients were followed until October 2020. This study analyzed treatment initiation, adherence to scheduled visits and outcomes in patients in whom management was assisted by the HCV-Phone.

Results
Out of 98 patient contacts via the HCV-Phone 74 attended treatment assessment at our clinic. While 15 (20%) patients were HCV-RNA negative and 1 (1%) patient did not initiate therapy, 58 patients were recruited for DAA therapy via the HCV-Phone. A total of 21 additional patients who started DAAs without HCV-Phone assistance required the use of the HCV-Phone infrastructure later on during treatment, resulting in a total of 79 HCV-Phone related DAA therapies. The poor adherence of patients previously diagnosed with HCV at our clinic is underlined by the long duration from HCV diagnosis to DAA therapy of median 37.0 months (IQR 2.7–181.1 months). A total of 55 (70%) HCV patients achieved a sustained virological response (SVR), 5 (6%) discontinued therapy, 1 (1%) had a reinfection, while 10 (13%) and 8 (10%) patients were lost during DAA therapy or follow-up, respectively.

Conclusion
The implementation of a physician-operated phone hotline for patients with HCV infection facilitated treatment initiation in an HCV population with poor adherence. Mainly due to losses to follow-up, the SVR rate remained suboptimal with 70%.
Gaze awareness and metacognitive suggestions by a pedagogical conversational agent: an experimental investigation on interventions to support collaborative learning process and performance
Authors: Hayashi Yugo 
Published: December 2020

AbstractResearch on collaborative learning has revealed that peer-collaboration explanation activities facilitate reflection and metacognition and that establishing common ground and successful coordination are keys to realizing effective knowledge-sharing in collaborative learning tasks. Studies on computer-supported collaborative learning have investigated how awareness tools can facilitate coordination within a group and how the use of external facilitation scripts can elicit elaborated knowledge during collaboration. However, the separate and joint effects of these tools on the nature of the collaborative process and performance have rarely been investigated. This study investigates how two facilitation methods—coordination support via learner gaze-awareness feedback and metacognitive suggestion provision via a pedagogical conversational agent (PCA)—are able to enhance the learning process and learning gains. Eighty participants, organized into dyads, were enrolled in a 2 × 2 between-subject study. The first and second factors were the presence of real-time gaze feedback (no vs. visible gaze) and that of a suggestion-providing PCA (no vs. visible agent), respectively. Two evaluation methods were used: namely, dialog analysis of the collaborative process and evaluation of learning gains. The real-time gaze feedback and PCA suggestions facilitated the coordination process, while gaze was relatively more effective in improving the learning gains. Learners in the Gaze-feedback condition achieved superior learning gains upon receiving PCA suggestions. A successful coordination/high learning performance correlation was noted solely for learners receiving visible gaze feedback and PCA suggestions simultaneously (visible gaze/visible agent). This finding has the potential to yield improved collaborative processes and learning gains through integration of these two methods as well as contributing towards design principles for collaborative-learning support systems more generally.
Chloris virgata (feather finger grass).
Authors: Rojas-Sandoval Julissa 
Published: December 2020

Abstract

Chloris virgata is a widespread and very variable weedy annual grass (Flora of China Editorial Committee, 2015). This species is a particularly aggressive invader of bare areas and degraded or disturbed native vegetation, and it has the potential to out-compete native vegetation in these habitats (Smith, 2002; Oviedo Prieto et al., 2012; Weeds of Australia, 2015). This weedy grass spreads from cultivation, pastures, gardens, disturbed areas and roadsides to nearby disturbed forest, creeks and riversides, native grasslands and coastal habitats such as coastal forests and sand dunes (Weeds of Australia, 2015; FAO, 2015; PIER, 2015). It also grows as a weed in agricultural lands (Vibrans, 2009). Currently, this species is regarded as an invasive and environmental weed in northern Australia (i.e., Queensland and the Northern Territory; Weeds of Australia, 2015) and as an invasive grass in Cuba, Palau, New Caledonia, the Galapagos Islands, and Hawaii (Wagner et al., 1999; Charles Darwin Foundation, 2008; Oviedo Prieto et al., 2012; PIER, 2015).

Abstract

Myriophyllum pinnatum is a perennial aquatic herb only reported as invasive in Cuba, where it is included in the management plan of the Ciénaga de Zapata Biosphere Reserve as a species that needs to be managed to prevent invasion of that wetland system. In some areas of its native range in North America, it is considered rare, endangered or extirpated due to habitat fragmentation and loss. In the USA, the species is considered endangered in Connecticut, Massachusetts, Indiana, New Jersey, New York, Rhode Island and Tennessee. M. pinnatum belongs to a genus recognized for the invasive species M. spicatum, M. aquaticum and M. heterophyllum.
Elodea canadensis (Canadian pondweed).
Authors: Duenas-Lopez Manuel Angel , Popay Ian , Dawson Hugh 
Published: December 2020

Abstract

Elodea canadensis is a submerged aquatic plant of slower flowing rivers, native to North America. It has been intentionally introduced into areas outside of its native range as an ornamental aquarium species. This species has a wide ecological tolerance and grows relatively fast. It is a perennial, overwintering in the deeper water, and reproducing asexually. Disturbance increases the dispersal of numerous propagules and the vigorous re-growth is enhanced through changes in availability of nutrients. E. canadensis can form dense mats which can interfere with recreational activities, navigation and port infrastructure. In addition to this, the dense mats outcompete native plant species and therefore decrease the biodiversity in an area. It also accentuates the accumulation of finer organic silts which enhances its growth further as nutrients are released. E. canadensis is considered invasive in Australia, New Zealand, Cuba, Alaska and the majority of European countries where it is present. Control is complicated and loss of fragments should be minimized to prevent further spread. It is included in the IUCN Red List, categorized as being of Least Concern. Thus, no conservation action is proposed or is necessary for this species.

Published: December 2020

Abstract

E. japonica is a good fodder grass cultivated for pasture in tropical and subtropical regions (Kumar, 2013; USDA-ARS, 2016). It has escaped from cultivation and naturalized principally in disturbed sites. This species behaves as a weed in abandoned pastures, cultivated land, disturbed sites, waste areas, and along roadsides and riparian areas (Barkworth et al., 2004; Flora of China Editorial Committee, 2016; PIER, 2016; PROTA, 2016). Currently, it is listed as invasive in Argentina, Brazil, and Cuba (Zuloaga et al., 2008; Oviedo Prieto et al., 2012; I3N-Brasil, 2016). It is well adapted to grow in seasonally waterlogged conditions and can be found growing in floodplain grassland and swampy grassland (Flora of Pakistan, 2016).
Ficus carica (common fig).
Authors: Datiles Marianne Jennifer 
Published: December 2020

Abstract

Ficus carica, the common fig, is a rapidly growing tree that can spread by both seeds and cuttings, and if left unattended will form dense thickets that displace native trees and shrubs (Weber, 2003). It is known to be invasive to Australia and the western United States (Weber, 2003) since the introduction of its pollinator wasp to the USA in 1900 (Hanelt et al., 2001); in California's wildland, it is reportedly threatening the state's increasingly rare riparian forests (California Invasive Plant Council, 2014). The species is listed as "casual alien, cultivation escape, environmental weed, garden thug, naturalised, noxious weed, weed" in the Global Compendium of Weeds (Randall, 2012), but is not listed in the Geographical Atlas of World Weeds (Holm, 1979) and is currently considered a low-risk species according to a risk assessment of the species prepared for Hawaii (PIER, 2014). Re-evaluation is recommended in the future.

Published: December 2020

Abstract
The objective of this research paper is to investigate the combustion and emission characteristics by developing a clean combustion phenomenon, with an improvement in efficiency in an internal combustion engine. Most of the commercial transportation is through the CI (Compressed Ignition) engine and these engines creates relatively high emission in the form of Oxides of Nitrogen (NOx) and Particulate Matter (PM). With an increase in fuel prices and emission norms globally, thus demands a clean combustion from IC engine. In order to overcome the above stated problems associated, a step ahead is taken by the use of Reactivity Controlled Combustion Ignition concept (RCCI). As per the experiment conducted RCCI is capable of achieving high thermal efficiency and low NOx and PM emissions. In this experiment a light-duty single-cylinder diesel engine is modified to run an RCCI mode using diesel and petrol as a fuel. The reduction and increase in efficiency and emissions has been obtained by carrying out a slight modification in the intake named as Port Fuel Injector (PFI) for using the Low Reactive Fuel (LRF). The engine speed is kept constant by varying the Start of Injection (SOI). The PFI injector is being run by using an Arduino setup, where the LRF injection will be monitored and controlled by the Arduino. Load is applied using an eddy current dynamometer. The experiment is run with two combinations fuels such diesel and diesel-petrol.
Experimental and numerical analysis of compression behaviour of 3D printed metal foams
Authors: Ramesh R , Prasanth A S , Krishna R , KoushikSundaram K , Arul MozhiSelvan R , Roy Abhishek 
Published: December 2020

Abstract
This article focuses on comparing the experimental and numerical compressive behaviour of metal foams. The metal foams were initially modelled in three configurations of pore sizes. Each configuration was 3D printed using a laser sintering metal additive manufacturing technique. Subsequently, quasi-static compression tests were conducted and their stress-strain curves were examined to ascertain the proof stress of the three configurations. A numerical simulation of the compressive behaviours of the three foams was then conducted and their results were correlated with those from experimentation to quantify the error in simulation. The compression tests revealed that, the compressive strength was a function of density and porosity of the metal foams. Further, the numerical results of compression behaviours were validated, with less than 5 % deviation from the experimental results for all three foam configurations.
Selfsimilarity of diffusions’ first passage times
Authors: Eliazar Iddo 
Published: December 2020

Abstract
Considering a general diffusion process that runs over the non-negative half-line, this paper addresses the first-passage time (FPT) to the origin: the time it takes the process to get from an arbitrary fixed positive level to the level zero. Inspired by the special features of Brownian motion, three types of FPT selfsimilarity are introduced: (i) stochastic, which holds in ‘real space’; (ii) Laplace, which holds in ‘Laplace space’; and (iii) joint, which is the combination of the stochastic and Laplace types. Analysis establishes that the three types of FPT selfsimilarity yield, respectively and universally, the following FPT distributions: inverse-gamma; inverse-Gauss; and Levy–Smirnov. Moreover, the analysis explicitly pinpoints the classes of diffusion processes that produce the three types of selfsimilar FPTs. Shifting from general diffusion dynamics to Langevin dynamics, it is shown that the three classes collapse, respectively, to the following specific processes: diffusion in a logarithmic potential; Brownian motion with drift; and Brownian motion. Also, the effect of the Girsanov transformation on the three types of selfsimilar FPTs is investigated, as well as the effect of initiating the diffusion process from its steady-state level (rather than from a fixed positive level). This paper presents a novel approach to the exploration of first-passage times.
Integrability and scattering of the boson field theory on a lattice
Authors: Campos Manuel , López Esperanza , Sierra Germán 
Published: December 2020

Abstract
A free boson on a lattice is the simplest field theory one can think of. Its partition function can be easily computed in momentum space. However, this straightforward solution hides its integrability properties. Here, we use the methods of exactly solvable models, that are currently applied to spin systems, to a massless and massive free boson on a 2D lattice. The Boltzmann weights of the model are shown to satisfy the Yang–Baxter equation with a uniformization given by trigonometric functions in the massless case, and Jacobi elliptic functions in the massive case. We diagonalize the row-to-row transfer matrix, derive the conserved quantities, and implement the quantum inverse scattering method. Finally, we construct two factorized scattering S matrix models for continuous degrees of freedom using trigonometric and elliptic functions. These results place the free boson model in 2D in the same position as the rest of the models that are exactly solvable à la Yang–Baxter, offering possible applications in quantum computation.

NO

storage and reduction (NSR) technology has been regarded as one of the most promising strategies for the removal of nitric oxides (NO

x
reduction has been confirmed in the past few decades. This work reports the NSR of nitric oxide (NO) by combining non-thermal plasma (NTP) and Co/Pt/Ba/γ-Al2O3 (Co/PBA) catalyst using methane as a reductant. The experimental results reveal that the NO
x
conversion of NSR assisted by NTP is notably enhanced compared to the catalytic efficiency obtained from NSR in the range of 150 °C–350 °C, and NO
x
conversion of the 8% Co/PBA catalyst reaches 96.8% at 350 °C. Oxygen (O2) has a significant effect on the removal of NO
x
, and the NO
x
conversion increases firstly and then decreases when the O2 concentration ranges from 2% to 10%. Water vapor reduces the NO
x
storage capacity of Co/PBA catalysts on account of the competition for adsorption sites on the surface of Co/PBA catalysts. There is a negative correlation between sulfur dioxide (SO2) and NO
x
conversion in the NTP system, and the 8% Co/PBA catalyst exhibits higher NO
x
conversion compared to other catalysts, which shows that Co has a certain SO2 resistance.
MXenes and the progress of Li–S battery development—a perspective
Authors: Balach Juan , Giebeler Lars 
Published: December 2020

Abstract
Lithium–sulfur (Li–S) battery has attracted tremendous interest owing to its high energy density at affordable costs. However, the irreversible active material loss and subsequent capacity fading caused by the uncontrollable shuttling of polysulfides have greatly hampered its commercial viability. MXenes, a novel class of 2D materials derived from nano-layered MAX phases, have been shown the potential to push the development of sulfur-based batteries to a next level owing to their high conductivity, strong polysulfide affinity and electrocatalytic properties. This perspective article focuses on the possible implications that MXene-based materials will have in the development of advanced sulfur-based batteries and their potential application in different upcoming technologies. In four sections possible developments are outlined which can be reached in the next 10 years, that enable a highly reliable, minimized Li–S battery finally combined with energy harvesters to fabricate autonomous power supplies for the next generation of microscaled devices like meteorological or geotechnical probes, wearable (medical) sensors or other suitable mobile devices. Finally, a flowchart illustrates the possible way to realize some important milestones for the certain possible steps with significant contributions of MXenes.

Abstract
Failures in hypothalamic kisspeptin/Kiss1r signaling are associated with infertility, and in vitro studies have shown that kisspeptin can modulate angiogenesis and immune activity. Because there is no in vivo research on the functional relationship between these factors in the reproductive system, especially in domestic cats, we evaluated the expression profile of kisspeptin/Kiss1r and angiogenic and immunological mediators in the genital tract of cyclic cats and of those with pyometra. The uterus of cats in diestrus exhibited greater gene and protein expression of Kiss1, as well as Vegf, Pigf, Mif, and Il6. In contrast, Kiss1r presented greater expression in proestrus/estrus, similarly to that observed for the immunostaining of INFγ, MIF, TNFα, and IL10. These factors were positively correlated with Kiss1 and/or Kiss1r, and a positive correlation between Kiss1 and Kiss1r was also observed in the uterus of cats during the estrous cycle. Cats with pyometra showed greater immunostaining of Kiss1 and Kiss1r on the endometrial surface and reduced immunostaining of Kiss1 in deep glands, whereas there was a significant reduction in Vegf, Pigf, Mif, and Il6 mRNA, and an increase in Tnf mRNA. The findings reveal that there is a gene correlation between kisspeptin/Kiss1r and angiogenic and immune mediators in the uterus of the domestic cat, which is modulated by the estrous cycle, and that pyometra affects the expression of these mediators. This study suggests, for the first time, a functional relationship between the Kiss/Kiss1r system and angiogenic and immune mediators in the female genital tract.
Late adult presentation of ALCAPA syndrome: need for a new clinical classification? A case report and literature overview
Authors: Lotman Eno-Martin , Karu Külliki , Mikkel Mehis , Elmet Märt 
Published: December 2020

Abstract

Background
Anomalous origin of the left main coronary artery from the pulmonary artery (ALCAPA) is a very uncommon congenital coronary artery anomaly, most commonly presenting in early infancy. Late adult presentation of ALCAPA syndrome is extremely rare.

Case summary
We present a case of a 76-year-old patient with first presentation of ALCAPA. The coronary anomaly was first diagnosed during elective coronary angiography. The case was discussed at the Heart Team meeting and as the patient was asymptomatic, had good coronary collateral circulation, a medical treatment strategy was chosen and the patient was discharged in a good physical condition. During 3 years of follow-up, the patient has experienced no cardiovascular complications.

Discussion
We hereby also discuss briefly the clinical presentation, epidemiology, diagnostics and treatment options for adults with newly diagnosed ALCAPA and discuss the need for a new clinical classification. Only a few cases have been published of septuagenarians or octogenarians with first presentation of ALCAPA. To our knowledge, the patient presented in our case was one of the least symptomatic patients during her eight decades of life.
