Published: February 2022

Abstract
Precooling showed promises treatment for chilling injury symptom in the fruit. The research aimed to determine the effect of pre-cooling dan coating treatment using chitosan to the internal browning symptoms of pineapples during cold storage at 10°C. The pineapples of cultivar “Smooth Cayenne” were treated with 6 treatments, namely P0C0 (no pre-cooling and no chitosan), P0C1 (no pre-cooling and chitosan), P1C0 (1-day pre-cooling and no chitosan), P1C1 (1-day pre-cooling and chitosan), P2C0 (3-day pre-cooling and no chitosan), P2C1 (3-day pre-cooling and chitosan). Fruits qualities were evaluated by their weight loss, firmness, chilling injury, and chemical compounds including titratable acidity, phenol compounds, and reducing sugar. The analyses were performed on day 7, 14, 21, 28, and 28+3 days of storage. Each treatment was replicated three times and the data was analyzed using factorial complete randomized design (CRD). The result showed that pre-cooling and chitosan was able to inhibit chilling injury and prolong the shelf life of “Smooth Cayenne” pineapple.

Abstract
The Rat was one of the main pests in oil palm plantations cause able to significantly reduce oil palm yield. This research aimed to know the role of T. alba in controlling rat pest attacks in oil palm plantations. Observations were made on estates that had different ratios/hectare of T. alba nest boxes such as Pantai Harapan Estate (1:54), Kruing Estate (1:80), and Sungai Mirah Estate (1: 162). The presence of T. alba was observed every month at each nest box. The attack rate of rats was observed every month during January – December 2020 through a census attack in each plant block. Kruing estate was the highest nest box occupancy rate of T. alba of 37 %. The occupancy rates of Pantai Harapan Estate and Sungai Mirah Estate were 31% and 6%, respectively. While the rate of rat attacks in Pantai Harapan Estate, Kruing Estate, and Sungai Mirah Estate were 0.70 % a, 0.60 % a, 2,30 % b, respectively. The barn owl T. alba can control the attack of rats naturally and reduce the use of rodenticide. Rodenticide applications at Bumitama Agri Ltd for rat pest control in 2020 also decreased by 45% when compared to applications in 2019.

Abstract
Fusarium basal rot (FBR) infecting shallot caused a significant yield loss to the shallot production. Severity of this disease was known to be highly diverse depending on the regions, varieties, cropping system applied and Fusarium species associated. This study was aimed to investigate the occurrence of Fusarium basal rot in several shallot cultivations in Bantul Regency. This study was carried out in five shallot fields representing midland (Imogiri Sub District) and lowland (Sanden and Kretek Sub Districts) of Bantul Regency. Survey of cropping system was performed in each field to identify the shallot varieties, intercropped as well as rotated crops. FBR occurrence were monitored in three different points per fields represented by 25 plants in each point. Our findings exhibited that cultural practice applied in shallot cultivation contributed more significant impact in decreasing the FBR occurrence compared to the geographical condition. FBR incidence varied among varieties and types of intercropping as well as rotation used. Among several aspects of cultural practice observed, application of intercropping and rotation suppressed the FBR infection significantly compared to the one cultivated in monocropping.

Authors: Sarjiyah  , Handoko N A 
Published: February 2022

Abstract
Demand for soybeans in Indonesia has not been matched by adequate soybean production. The productivity of soybean (Glycine max L.) in Indonesia is still low, one of which is the decrease in soil fertility due to the continuous use of inorganic fertilizers. Increasing soybean productivity can be done through the management of soil fertility by utilizing unused plant residues, one of which is sugar palm bagasse as organic fertilizer. This study aims to obtain the optimal balance between urea and sugar palm bagasse with an optimal mixture of gliricidia leaves to increase soybean yields. This research was conducted at the Greenhouse and Experimental Field, Faculty of Agriculture, Muhammadiyah University of Yogyakarta from June to October 2020. This study used a single factor design, namely the balanced dose of urea and sugar palm bagasse compost with a mixture of gliricidia leaves, consisting of five treatments, namely 1) Urea 100%. + 0% sugar palm bagasse compost; 2) 75% Urea + 25% sugar palm bagasse compost, 3) 50% Urea + 50% sugar palm bagasse compost, 4) 25% Urea + 75% sugar palm bagasse compost, and 5) 0% Urea + 100% sugar palm bagasse compost. Each treatment was repeated three times and arranged in a randomized complete block design (RCBD). The results showed that the balance of using urea and bagasse compost with the optimal mixture of gliricidia leaves was 0% urea + 100% compost for bagasse which increased the soybean yield by 34% and was not significantly different from other treatments.

Abstract
Among various types of resistance of the rock mass to the penetration of a solid body into it, those are determined, with the overcoming of which not rebound, but the depth of penetration (viscous-plastic resistance) is associated. It is shown how at a given initial speed of the tool movement, at the depth and time of penetration measured in experiments, for a given geometry of the tool, the desired resistance function consisting of a constant term and a function that depends on the speed of movement is restored. More acceptable is the geometry of the tool at which the resistance of the medium to penetration for a given depth is minimal.

Analysis of structure and material in the southwest of the Talnakh ore cluster
Authors: Miroshnikova LK , Yu Mezentsev A , Semenyakina NV 
Published: February 2022

Abstract
The issues of metallogenetic modeling of ore-forming systems for search purposes when studying sides and deep horizons of the mined deposits are considered. The object of the study is the geological and geochemical conditions of ore accumulation of various mineral composition and the concentration of useful components in various sections of the Talnakh ore-forming system. Mineral and geochemical zoning of the deposits reflect the degree of contamination of primary silicate and magmatic melts with crustal material. On the western and southern sides of the ore-forming system, ore mineralization is represented by low-sulfur associations of chalcopyrite minerals and is specialized in Cu–Ni–Co. The geochemical analysis of isotopes δ34S, 40Ar/36Ar, δ65Cu, 87Sr/86Sr suggests that the process of ore formation on the sides of the Talnakh ore cluster occurs under intense influence of the crust (sulfur source evaporite rocks) and near-surface water on the fluid in melting-fractionated sulphide magma enriched with copper, which results in the formation of chalcopyrite ore.

Published: February 2022

Abstract
Reconfigurable plasmonic materials are crucial components in active photonic devices for optical communication, signal processing, and sensing applications. Certain candidates including transparent conducting oxides, small-bandgap semiconductors (i.e. Ge, InSb), and conducting polymers can exhibit switchable free carrier concentrations triggered by optical, electrical or thermal excitations. Here, we show that aligned films of single-walled carbon nanotubes (SWCNTs) can serve as all-optically tunable plasmonic material in the mid-infrared range, thereby adding them to the library of switchable plasmonic materials. Interband optical pumping with femtosecond laser pulses results in the photoexcitation of free charge carriers, which transiently blueshifts the plasmon resonances of patterned, periodic SWCNT nano-resonators spanning the mid-infrared spectral range from 1700 to 2700 cm−1. The ultrafast plasmon modulation exhibits a nearly single-picosecond decay time, attributed to interband carrier relaxation and inter-tube charge transfer. Given that aligned films of SWCNTs have high thermal stability, excellent photostability, epsilon-near-zero property, and extremely large optical anisotropy, their dynamic tunability represents a promising pathway towards active optical devices in the technologically important mid-infrared range.
Misconceptions About the Direction of Bias From Nondifferential Misclassification
Authors: Yland Jennifer J , Wesselink Amelia K , Lash Timothy L , Fox Matthew P 
Published: February 2022

AbstractMeasurement error is pervasive in epidemiologic research. Epidemiologists often assume that mismeasurement of study variables is nondifferential with respect to other analytical variables and then rely on the heuristic that “nondifferential misclassification will bias estimates towards the null.” However, there are many exceptions to the heuristic for which bias towards the null cannot be assumed. In this paper, we compile and characterize 7 exceptions to this rule and encourage analysts to take a more critical and nuanced approach to evaluating and discussing bias from nondifferential mismeasurement.
Unravelling the Idiosyncrasy and Commonality in L2 Developmental Processes: a Time-Series Clustering Methodology
Authors: Peng Hongying , Lowie Wander , Jager Sake 
Published: February 2022

Abstract
Learners’ self-initiated language learning with mobile technology occurring outside the classroom is often contextualized, heterogeneous, and idiosyncratic. In this study, we propose a time-series clustering methodology for researching informal mobile language learners’ learning and development of another language, with a view to unravelling the essential uniquenesses and commonalities in learners’ developmental processes. Intensive longitudinal writing samples from nine English learners in China were collected and analysed with the methodology proposed, which first depicted individual-level developmental trajectories of writing complexity that were often idiographic or individual-specific, and then distilled salient developmental patterns that transcended the individual heterogeneity. These typically occurring patterns across individuals demonstrated a more predictable and interpretable manifestation of informal language learners’ developmental processes. Methodological and pedagogical implications of adopting the time-series clustering methodology are discussed.
Optimal minimax random designs for weighted least squares estimators
Authors: Azriel D 
Published: February 2022

Summary
This work studies an experimental design problem where the values of a predictor variable, denoted by $x$, are to be determined with the goal of estimating a function $m(x)$, which is observed with noise. A linear model is fitted to $m(x)$, but it is not assumed that the model is correctly specified. It follows that the quantity of interest is the best linear approximation of $m(x)$, which is denoted by $\ell(x)$. It is shown that in this framework the ordinary least squares estimator typically leads to an inconsistent estimation of $\ell(x)$, and rather weighted least squares should be considered. An asymptotic minimax criterion is formulated for this estimator, and a design that minimizes the criterion is constructed. An important feature of this problem is that the $x$ values should be random, rather than fixed. Otherwise, the minimax risk is infinite. It is shown that the optimal random minimax design is different from its deterministic counterpart, which was studied previously, and a simulation study indicates that it generally performs better when $m(x)$ is a quadratic or a cubic function. Another finding is that, when the variance of the noise goes to infinity, the random and deterministic minimax designs coincide. The results are illustrated for polynomial regression models and a generalization is given in the Supplementary Material.
Evolution of transoral endoscopic thyroidectomy vestibular approach according to the IDEAL framework
Authors: Lee Shen-Han , Moorthy Ram , Nagala Sidhartha 
Published: February 2022

AbstractBackgroundThe IDEAL Framework is a scheme for safe implementation and assessment of surgical innovation. The transoral endoscopic thyroidectomy vestibular approach (TOETVA) is a new innovation in thyroid surgery that eliminates the need for a cervical incision. Despite considerable interest and adoption worldwide, significant scepticism remains regarding the outcomes and cost-effectiveness for healthcare systems. The aim of this narrative review was to appraise the available literature and examine whether TOETVA has progressed in line with the IDEAL Framework.MethodsA literature review of PubMed with a focus on historical and landmark studies was undertaken to classify the evidence according to the different stages of the IDEAL Framework.ResultsSeveral different transoral approaches were developed by a small of number of surgeon-innovators on animals and cadavers, and subsequently in first-in-human studies. The trivestibular approach emerged as the safest technique, with further refinements of this technique culminating in TOETVA. The basic steps and indications for this technique have been standardized and it is now being replicated by early adopters in many centres worldwide. The development of TOETVA has closely aligned with the IDEAL Framework, and is currently at stage 2B (Exploration).ConclusionThere is need for multi-institutional collaborations and international registry studies to plan high-quality randomized trials comparing TOETVA with other remote-access approaches and collect long-term follow-up data. In countries where TOETVA has yet to be adopted, the IDEAL Framework will be a useful roadmap for government regulators and professional societies to evaluate, regulate, and provide best practice recommendations for the adoption of this technique.

Abstract
Autism spectrum disorder (ASD) is a common neurodevelopmental disorder characterized by a core deficit in social processes. However, it is still unclear whether the core clinical symptoms of the disorder can be reflected by the temporal variability of resting-state network functional connectivity (FC). In this article, we examined the large-scale network FC temporal variability at the local region, within-network, and between-network levels using the fuzzy entropy technique. Then, we correlated the network FC temporal variability to social-related scores. We found that the social behavior correlated with the FC temporal variability of the precuneus, parietal, occipital, temporal, and precentral. Our results also showed that social behavior was significantly negatively correlated with the temporal variability of FC within the default mode network, between the frontoparietal network and cingulo-opercular task control network, and the dorsal attention network. In contrast, social behavior correlated significantly positively with the temporal variability of FC within the subcortical network. Finally, using temporal variability as a feature, we construct a model to predict the social score of ASD. These findings suggest that the network FC temporal variability has a close relationship with social behavioral inflexibility in ASD and may serve as a potential biomarker for predicting ASD symptom severity.

Abstract

Background and Aims
Perianal fistulising disease can affect up to 25% of patients with Crohn’s disease [CD] and lead to significant morbidity. Although the role of the gut microbiota in inflammatory bowel disease [IBD] has been increasingly recognised, its role in fistula development has scarcely been studied. Here, we aimed to define the microbial signature associated with perianal fistulising CD in children.

Methods
A prospective observational study including children age 6-18 years with a diagnosis of perianal fistulising CD was conducted. Stool samples and rectal and perianal fistula swabs were collected. Stool samples and rectal swabs from children with CD without perianal disease and healthy children were included as comparison. Whole shotgun metagenomic sequencing was performed.

Results
A total of 31 children [mean age 15.5 ± 3.5 years] with perianal CD were prospectively enrolled. The fistula-associated microbiome showed an increase in alpha diversity and alteration in the abundance of several taxa compared with the rectal- and faecal-associated microbiome with key taxa belonging to the Proteobacteria phylum. Genes conferring resistance to the clinically used antibiotic regimen ciprofloxacin and metronidazole were found in the three sample types. In comparison with children without the perianal phenotype [N = 36] and healthy controls [N = 41], the mucosally-associated microbiome of children with perianal CD harboured a reduced butyrogenic potential. Linear discriminant analysis identified key taxa distinguishing the rectal mucosally-associated microbiome of children with perianal CD from children without this phenotype.

Conclusions
The microbial community within CD-related anorectal fistula is compositionally and functionally unique. Taken together, these findings emphasise the need to better understand the ecosystem of the fistula milieu to guide development of novel microbiome-based strategies in this CD phenotype.
New York in Slices: The Victorian Origins of The Bonfire of the Vanities
Authors: Abraham Adam 
Published: February 2022

Abstract
The Bonfire of the Vanities, Tom Wolfe’s first novel, was a bestseller in the 1980s, when it captured its historical moment of yuppie excess, urban corruption, and vanity. Less recognized today are the book’s origins as an experiment in reviving Victorian modes of publication. Taking Dickens and Thackeray, Balzac and Zola as his models, Wolfe planned to write what he conceived of as a new nineteenth-century novel—multiplot and multivalent—an anatomy of New York City. What is more, The Bonfire of the Vanities was first published serially, in Rolling Stone magazine, from 1984 to 1985. This article will explore the Victorian provenance of Wolfe’s novel, in particular by rereading the original serial parts.
