Grammar as validity evidence for assessing L2 interactional competence
Authors: Youn Soo Jung 
Published: January 2023

Abstract
This study examines how L2 learners of English at different pragmatic performance levels implement requests during role-play assessment interaction. In doing so, the role of grammar-for-interaction as validity evidence of assessing interactional competence is explicated. Using qualitative and quantitative data, the following research questions are investigated: (a) How do learners use grammar differently depending on the role-play request situations they are engaged in?; (b) To what extent are learners’ role-play performance levels associated with the ability to use context-sensitive grammar when co-constructing request sequences? The data come from a database of 102 L2 English learners’ role-play interactions with 45 hours of recorded interaction in total. The role-play assessment tasks include various real-life communicative situations, such as requests designed for specific interlocutors in a university context. Using conversation analysis, the role-play interactions at different performance levels were analyzed. Sequential analyses showed that higher-level learners utilized diverse grammatical formats that are sensitive to their sequential positions and contingencies associated with requests. As quantitative evidence, the relationship between selected grammatical constructions and the learners’ role-play performance levels determined by trained raters was examined. With this, I discuss the role of grammar-for-interaction in defining and assessing interactional competence.

Main text
Three new participations in the BIPM.RI(II)-K1.I-131 comparison have been added to the previous results and this has produced a revised value for the key comparison reference value (KCRV), calculated using the power-moderated weighted mean. A link has been made to the CCRI(II)-S6.I-131 comparison piloted by the International Atomic Energy Agency (IAEA) in 2006, based on the participation of CMI-IIR in both comparisons. One NMI used the S6 comparison to update its degree of equivalence. The results of two NMIs in the CCRI(II)-S6.I-131 comparison were superseded by a more recent APMP.RI(II)-K2.I-131 comparison. The degrees of equivalence between each equivalent activity measured in the International Reference System (SIR) and the KCRV have been calculated and the results are given in the form of a table for the latest results in the BIPM.RI(II)-K1.I-131, and the linked CCRI(II)-S6.I-131, APMP.RI(II)-K2.I-131 and EURAMET.RI(II)-K2.I-131 comparisons. A graphical presentation is also given.

Quadrupole and octupole states in 152Sm using the proton–neutron interacting boson model
Authors: Hu Bao-Yue , Zhang Yu , Na Gui-Xiu , Wang Sheng-Nan , Teng Wei 
Published: January 2023

Abstract
A scheme of solving the proton–neutron interacting boson model (IBM-2) in terms of the SU(3) basis is introduced, by which the IBM-2 coupled with an octupole boson is applied to describe the low-energy structure of the critical point nucleus, 152Sm. The results indicate that the spectral properties of both the positive-parity bands and negative-parity bands in this nucleus can be well captured by the IBM-2 calculations through a simple Hamiltonian, thus providing an example of the IBM-2 in a unified description of quadrupole and octupole states in a transitional system. In addition, a statistical analysis of the low-spin states in the model is also provided.

Abstract
Introduction: Although the use of 68Ga has increased substantially in nuclear medicine over the last decade, there is limited information available on occupational exposure due to 68Ga. The purpose of this study is to determine the occupational extremity exposure during the preparation, dispensing and administration of 68Ga-labelled radiopharmaceuticals. Method: Workers in eight centres wore a ring dosimeter for all tasks involving 68Ga-labelled radiopharmaceuticals for a minimum of one month. Additionally, the fingertip dose was monitored in two centres and the hand with the highest ring dose during 68Ga procedures was also identified in one centre. Results: The median normalised ring dose for 68Ga procedures was found to be 0.25 mSv GBq−1 (range 0.01–3.34). The normalised 68Ga ring doses recorded in this study are similar to that found in the literature for 18F. This study is consistent with previous findings that the highest extremity dose is found on the non-dominant hand. A limited sub study in two of the centres showed a median fingertip to base of the finger dose ratio of 4.3. Based on this median ratio, the extrapolated annual 68Ga fingertip dose for 94% of the workers monitored in this study would be below Category B dose limit (150 mSv) and no worker would exceed Category A dose limit (500 mSv). Conclusion: When appropriate shielding and radiation protection practices are employed, the extremity dose due to 68Ga is comparable to that of 18F and is expected to be well below the regulatory limits for the majority of workers.
Mn–N–C catalysts derived from metal triazole framework with hierarchical porosity for efficient oxygen reduction
Authors: Wang Huiying , Kong Ziyan , Wang Minghao , Huang Bing , Guan Lunhui 
Published: January 2023

Abstract
Manganese and nitrogen co-doped porous carbon (Mn–N–C) are proposed as one of the most up-and-coming non-precious metal electrocatalysts to substitute Pt-based in the oxygen reduction reaction (ORR). Herein, we chose metal triazole frameworks as carbon substrate with hierarchical porosity for trapping and anchoring Mn-containing gaseous species by a mild one-step pyrolysis method. The optimized Mn–N–C electrocatalyst with a large metal content of 1.71 wt% and a volume ratio of 0.86 mesopores pore delivers a superior ORR activity with a half-wave potential (E
1/2) of 0.92 V in 0.1 M KOH and 0.78 V in 0.1 M HClO4. Moreover, the modified Mn–N–C catalyst showed superior potential cyclic stability. The E
1/2 remained unchanged in 0.1 M KOH and only lost 6 mV in 0.1 M HClO4 after 5000 cycles. When applied as the cathode catalyst in Zn-air battery, it exhibited a maximum peak power density of 176 mW cm−2, demonstrating great potential as a usable ORR catalyst in practical devices.
Resonances and signal to noise ratio of electromagnetic sensors
Authors: Chui S T , Lin Zhifang , Ji Zian 
Published: January 2023

Abstract
We illustrate the concept of the resonance for noise by considering the example of the current induced by an external electromagnetic field and the noise current in the well studied split ring resonantors in the thin wire limit, which is analytically tractable. We found that both the signal and the noise exhibit resonances at the same frequencies. However, their ratio exhibits interesting frequency dependences which also is a function of the nature of the external driving field. This previously unanticipated result suggests the signal to noise ratio does not just depend on the resonance frequency; further study is required of the fundamental physics for different structures and help improve the design of devices.
ALP dark matter mini-clusters from kinetic fragmentation
Authors: Eröncel Cem , Servant Géraldine 
Published: January 2023

Abstract
We show that very compact axion mini-clusters can form
in models where axion-like-particle (ALP) dark matter is produced via the kinetic misalignment mechanism, which is well-motivated in pre-inflationary U(1) symmetry breaking scenarios.
This is due to ALP fragmentation.
We predict denser halos than what has been obtained so far in the literature
from standard misalignment in post-inflationary U(1) breaking scenarios or from large misalignment.
The main reason is that adiabatic fluctuations are significant at early times, therefore, even if amplification from parametric resonance effects is moderate, the final size of ALP fluctuations is larger in kinetic misalignment.
We compare halo mass functions and halo spectra obtained in kinetic misalignment, large misalignment and standard misalignment respectively. Our analysis does not depend on the specific model realization of the kinetic misalignment mechanism. We present our results generally as a function of the ALP mass and the ALP decay constant only. We show that a sizable region of this ALP parameter space can be tested by future experiments that probe small-scale structures.
Molecular dynamics study on the slippage of liquid lithium flow in tungsten nanochannels
Authors: Liu S. , Yu X. 
Published: January 2023

Abstract
As the use of liquid lithium (Li) as the plasma facing material in a fusion device becomes widespread, more and more research work has been dedicated to the numerical simulations of Li flow based on the Navier–Stokes equations. However, the slip condition of Li on a solid surface hasn’t been fully understood. The most common and simplest boundary condition, which is no-slip, is just one of the allowable conditions ranging from pure slip to multilayer locking. In this work, molecular dynamics simulations of the Couette flow were performed to investigate the slip properties of liquid Li on tungsten (W) surfaces. The atomic structures near the surfaces were inspected. The influence of temperature, lattice orientation and biaxial strain of wall surfaces, as well as the surface roughness, were discussed. It was found that the slip length is always negative suggesting that the wall always retards the movement of liquid Li. Among all the factors, surface roughness has the most significant effects on the slippage. Two sectional linear relationships between the slip length and the height of the roughness elements were discovered. As the height of roughness elements reaches a critical point, micro vortexes begin to form and change the slope of the linear relationship.
Conversion of a mixture of date palm wastes to mesoporous activated carbon for efficient dye adsorption

Published: January 2023

Abstract
In this study, we aimed to develop mixture activated carbon (MAC) from a mixture of date palm wastes (petiole, rachis and fiber) through hydrothermal carbonization and microwave-assisted H3PO4 activation and evaluate its adsorption capacity to remove Remazol brilliant blue R (RBBR) from aqueous solution. The MAC was found to be mesoporous, with an average pore diameter and BET surface area of 2.61 nm and 641.23 m2 g−1, respectively. The zeta potential and FTIR results demonstrated that the surface of MAC was negatively charged in its natural state and filled with functional groups such as phenyl, secondary amine, alkyne, aldehyde, and hydroxy groups. The adsorption capacity and percentage removal of RBBR increased and decreased, respectively, when the initial concentration increased. Maximum removal of RBBR was achieved at pH 3 (96.69 mg g−1) and at 30 °C of solution temperature (85.79 mg g−1). Langmuir and pseudo-first-order were the best isotherm and kinetic models for describing the RBBR-MAC adsorption system, respectively. The thermodynamic parameters of ΔH°, ΔS°, ΔG°, and Ea implied that this adsorption system was exothermic, increased randomness at the liquid-solid interface, and was spontaneous and controlled by the physisorption type of sorption, respectively.
Lamination of inkjet-printed Ag electrodes for highly patternable and customizable polymer light-emitting diodes
Authors: Yoon Hyungsoo , Jeong Sujin , Lee Byeongmoon , Kim Dahyun , Park Jongjang , Hong Yongtaek 
Published: January 2023

Abstract
Inkjet printing that ensures superior patternability and customizability can be fully exploited as top electrodes in thin-film-based light-emitting devices. However, direct inkjet printing onto multi-layered thin films severely damages the underlying functional layers due to intermixing with the ink solvents, resulting in poor device efficiencies. Here, we report a lamination of inkjet-printed Ag electrodes as a top cathode for polymer light-emitting diodes (PLEDs). The organometallic Ag ink was printed on surface-modified elastomers with stable wettability, and drop spacing was further optimized for low surface roughness. The lamination of Ag cathodes establishes intimate contact between the electrodes and the functional layers, allowing light emission of PLEDs along the printed patterns. Furthermore, additional heat treatment improves the electron injection, resulting in a reduction of turn-on voltage and higher current/power efficiencies. To illustrate the practicability of our laminated PLEDs, we demonstrate passive-matrix driven PLEDs with all-inkjet-printed electrodes by laminating the top cathode arrays crossing the bottom inkjet-printed anodes.
Electromigration failure in inkjet-printed Ag conductive lines
Authors: Jepiti Prabhakar , Yoon Sukeun , Kim Jihoon 
Published: January 2023

Abstract
Electromigration (EM) is crucial to the reliability of most conductive lines used in electronics. In the present study, the EM characteristics of inkjet-printed Ag conductive lines were analyzed under various EM acceleration conditions to comprehend the EM failure behaviors associated with inkjet-printed Ag lines with nanoparticle inks. The evolution of the porosity level in the microstructure of the inkjet-printed Ag lines during the EM test was investigated to locate the EM failure positions in the line and identify the main driving force for EM mass transport. Two theoretical models (resistometric and Black’s) were employed to analyze the activation energy and expected lifetime of inkjet-printed Ag lines. This study indicates that the EM of Ag cations is directed toward the cathode by the direct force resulting from the electric field–ion interaction, resulting in EM failure near the anode and hillock formation near the cathode of the inkjet-printed Ag lines. The activation energy computed from the theoretical models suggests that the surface diffusion of Ag through the inkjet-printed line plays an important part in the EM failure mechanism. This research was a pioneering attempt to experimentally investigate the EM performance of inkjet-printed Ag lines.
Understanding the light-induced oxygen vacancy in the photochemical conversion
Authors: Xu Chenyu , Luo Jing-Li 
Published: January 2023

Abstract
The formation of light-induced oxygen vacancy (VO) is detected and confirmed on the surface of various metal-oxide-based semiconductors under mild reaction conditions with low cost energy source (sunlight). This self-structural transformation of the materials can bring about new characteristics and functionalities, which has inspired many researchers to explore the applications of light-induced VO in the photochemical conversion. In this perspective, generating and maintaining the light-induced VO are discussed based on some of the important work in the field of photochemical conversion. The effects and utilizations of the light-induced VO are revealed including the models proposed to explain mechanism. Then, the electric current measurements and key challenges of the light-induced VO are also summarized in a comprehensive introduction. Finally, some important aspects and questions in terms of the future research of light-induced VO are emphasized via discussing the potential contribution and development. And the schematic of future developments for light-induced VO is provided based on loop-locked materials design, light engineering and mechanism investigation.
Deep learning predicts the impact of regulatory variants on cell-type-specific enhancers in the brain
Authors: Zheng An , Shen Zeyang , Glass Christopher K , Gymrek Melissa 
Published: January 2023

Abstract

Motivation
Previous studies have shown that the heritability of multiple brain-related traits and disorders is highly enriched in transcriptional enhancer regions. However, these regions often contain many individual variants, while only a subset of them are likely to causally contribute to a trait. Statistical fine-mapping techniques can identify putative causal variants, but their resolution is often limited, especially in regions with multiple variants in high linkage disequilibrium. In these cases, alternative computational methods to estimate the impact of individual variants can aid in variant prioritization.

Results
Here, we develop a deep learning pipeline to predict cell-type-specific enhancer activity directly from genomic sequences and quantify the impact of individual genetic variants in these regions. We show that the variants highlighted by our deep learning models are targeted by purifying selection in the human population, likely indicating a functional role. We integrate our deep learning predictions with statistical fine-mapping results for 8 brain-related traits, identifying 63 distinct candidate causal variants predicted to contribute to these traits by modulating enhancer activity, representing 6% of all genome-wide association study signals analyzed. Overall, our study provides a valuable computational method that can prioritize individual variants based on their estimated regulatory impact, but also highlights the limitations of existing methods for variant prioritization and fine-mapping.

A heuristic algorithm solving the mutual-exclusivity-sorting problem
Authors: Vinceti Alessandro , Trastulla Lucia , Perron Umberto , Raiconi Andrea , Iorio Francesco 
Published: January 2023

Abstract

Motivation
Binary (or Boolean) matrices provide a common effective data representation adopted in several domains of computational biology, especially for investigating cancer and other human diseases. For instance, they are used to summarize genetic aberrations—copy number alterations or mutations—observed in cancer patient cohorts, effectively highlighting combinatorial relations among them. One of these is the tendency for two or more genes not to be co-mutated in the same sample or patient, i.e. a mutual-exclusivity trend. Exploiting this principle has allowed identifying new cancer driver protein-interaction networks and has been proposed to design effective combinatorial anti-cancer therapies rationally. Several tools exist to identify and statistically assess mutual-exclusive cancer-driver genomic events. However, these tools need to be equipped with robust/efficient methods to sort rows and columns of a binary matrix to visually highlight possible mutual-exclusivity trends.

Results
Here, we formalize the mutual-exclusivity-sorting problem and present MutExMatSorting: an R package implementing a computationally efficient algorithm able to sort rows and columns of a binary matrix to highlight mutual-exclusivity patterns. Particularly, our algorithm minimizes the extent of collective vertical overlap between consecutive non-zero entries across rows while maximizing the number of adjacent non-zero entries in the same row. Here, we demonstrate that existing tools for mutual-exclusivity analysis are suboptimal according to these criteria and are outperformed by MutExMatSorting.

AbstractBackgroundFactors excluding postoperative pancreatic fistula (POPF), facilitating early drain removal and hospital discharge represent a novel approach in patients undergoing enhanced recovery after pancreatic surgery. This study aimed to establish the relevance of neutrophil-to-lymphocyte ratio (NLR) in excluding POPF after pancreatoduodenectomy (PD).MethodsA prospectively maintained database of patients who underwent PD at two high-volume centres was used. Patients were divided into three cohorts (training, internal, and external validation). The primary endpoints of this study were accuracy, optimal timing, and cutoff values of NLR for excluding POPF after PD.ResultsFrom 2012 to 2020, in a 2:1 ratio, 451 consecutive patients were randomly sampled as training (n = 301) and validation (n = 150) cohorts. Additionally, the external validation cohort included 197 patients between 2018 and 2020. POPF was diagnosed in 135 (20.8 per cent) patients. The 90-day mortality rate was 4.1 per cent. NLR less than 8.5 on postoperative day 3 (OR, 95 per cent c.i.) was significantly associated with the absence of POPF in the training (2.41, 1.19 to 4.88; P = 0.015), internal validation (5.59, 2.02 to 15.43; P = 0.001), and external validation (5.13, 1.67 to 15.76; P = 0.004) cohorts when adjusted for relevant clinical factors. Postoperative outcomes significantly differed using this threshold.ConclusionNLR less than 8.5 on postoperative day 3 may be a simple, independent, cost-effective, and easy-to-use criterion for excluding POPF.
Digest: Multiple selective pressures drive color diversity in moths
Authors: Lungstrom Linnea L , Fedder Zachary J F 
Published: January 2023

Abstract
How are color polymorphisms maintained within populations? De Pasqual et al. (2022) showed that female wood tiger moths (Arctia plantaginis) that were heterozygous for a wing color gene had higher fertility, hatching success, and offspring survival. These findings suggest that the complex interaction between heterozygote advantage and pleiotropic effects maintains color variability through a balance between multiple and competing selective pressures in wild populations.
