Published: November 2022

AbstractDue to its advantages over open surgery and conventional laparoscopy, uptake of robot-assisted surgery has rapidly increased. It is important to know whether the existing open or laparoscopic skills of robotic novices shorten the robotic surgery learning curve, potentially reducing the amount of training required. This systematic review aims to assess psychomotor skill transfer to the robot in clinical and simulated settings. PubMed, EMBASE, Cochrane Library and Scopus databases were systematically searched in accordance with PRISMA guidelines from inception to August 2021 alongside website searching and citation chaining. Article screening, data extraction and quality assessment were undertaken by two independent reviewers. Outcomes included simulator performance metrics or in the case of clinical studies, peri- and post-operative metrics. Twenty-nine studies met the eligibility criteria. All studies were judged to be at high or moderate overall risk of bias. Results were narratively synthesised due to heterogeneity in study designs and outcome measures. Two of the three studies assessing open surgical skill transfer found evidence of successful skill transfer while nine of twenty-seven studies evaluating laparoscopic skill transfer found no evidence. Skill transfer from both modalities is most apparent when advanced robotic tasks are performed in the initial phase of the learning curve but quality and methodological limitations of the existing literature prevent definitive conclusions. The impact of incorporating laparoscopic simulation into robotic training curricula and on the cost effectiveness of training should be investigated.
Relationships Between Maternal Selected Metals (Cu, Mg, Zn and Fe), Thyroid Function and Blood Glucose Levels During Pregnancy
Authors: Zhang WeiYi , Liang HongPing 
Published: November 2022

AbstractThe aim of this study were to understand the intake of selected metals (copper (Cu), zinc (Zn), iron (Fe) and magnesium (Mg)) during pregnancy; to detect serum Cu, Mg, Zn and Fe levels in pregnant women; to analyze the relationships among the selected metals, maternal thyroid function and fasting blood glucose (FBG) levels; to investigate the impact of the selected metals and maternal thyroid function on the risk of gestational diabetes mellitus (GDM); and to provide clinical value for the rational intake of the selected metals and iodine during pregnancy to ensure normal fetal development. The population was recruited from pregnant women presenting to the obstetrics outpatient clinic of Shanxi Provincial People's Hospital (February 2021 to April 2022). Selected metal, thyroid hormone (TH (free thyroxine (FT4), free tri-iodothyronine (FT3), and thyroid-stimulating hormone (TSH)) and FBG levels were measured in pregnant women during early, middle and late pregnancy. Covariance analysis was used to analyze the overall trends in selected metal, TH and FBG levels during pregnancy, and binary logistic regression models were used to assess the impacts of the selected metals and thyroid function on the risk of GDM. In addtion, the potential mediation effects of thyroid functions were explored in the mediation analyses. A total of 65 pregnant women were included in this study. Regression models showed that maternal Mg and Cu levels were positively associated with the risk of GDM, conversely, logFT4 was negatively associated with the risk of GDM. Mediation analyses suggested that the associations between the selected metals (Zn, Cu and Mg) and GDM might be mediated by FT3 levels, and that the Cu-GDM and Zn-GDM association could be explained by FT4 levels. Additionally, the Zn-GDM association could also potentially be mediated by the FT3/FT4 ratio. Our findings suggest that Mg, Cu and FT4 levels may act as influencing factors for the development of GDM, and maternal FT3, FT4 and the FT3/FT4 ratio might be the potential mediators of the associations between the selected metals and GDM risk during pregnancy.
Families of Discrete Circular Distributions with Some Novel Applications
Authors: Mardia Kanti V. , Sriram Karthik 
Published: November 2022

AbstractWe give a unified treatment of constructing families of circular discrete distributions. Some of these families are deduced from established distributions such as von Mises and wrapped Cauchy. Some others are derived directly such as a flexible family based on trigonometric sums and the circular location family. Results interrelating these families are discussed. These distributions have been motivated by two examples of discrete circular data: casino roulette spins and smart health acrophase monitoring, and these data are analyzed using our proposed models. We discuss how using continuous circular models for circular discrete data can be misleading.
Reorienting Modernism in Arabic and Persian Poetry
Authors: Thompson Levi 
Published: November 2022

Re-orienting Modernism in Arabic and Persian Poetry is the first book to systematically study the parallel development of modernist poetry in Arabic and Persian. It presents a fresh line of comparative inquiry into minor literatures within the field of world literary studies. Focusing on Arabic-Persian literary exchanges allows readers to better understand the development of modernist poetry in both traditions and in turn challenge Europe's position at the center of literary modernism. The argument contributes to current scholarly efforts to globalize modernist studies by reading Arabic and Persian poetry comparatively within the context of the Cold War to establish the Middle East as a significant participant in wider modernist developments. To illuminate profound connections between Arabic and Persian modernist poetry in both form and content, the book takes up works from key poets including the Iraqis Badr Shakir al-Sayyab and Abd al-Wahhab al-Bayati and the Iranians Nima Yushij, Ahmad Shamlu, and Forough Farrokhzad.
Observations of pumping and vortex dynamics due to a cylinder oscillating normal to a plane wall

Published: November 2022

Understanding the fluid dynamics associated with a circular cylinder oscillating normal to a plane wall is important for safe design of offshore infrastructure, such as power cables and pipeline risers. This paper investigates the fluid dynamics of an oscillating cylinder with no imposed incident current experimentally using flow visualisation and force measurements where the ratio of the cylinder Reynolds number (

$Re$

) to Keulegan–Carpenter number (

$KC$

) is

$\beta =500$

and

$KC$

varies between 2 and 12. The minimum distance between the cylinder and wall was between 12.5 % and

$50\,\%$

of the diameter. Across this parameter space three primary vortex flow regimes were observed: (i) for

$KC\leq 5$

, the flow field is approximately symmetric about the cylinder centreline and the velocity field between the cylinder and the wall resembled a pumping flow in phase with cylinder motion, which is well predicted by potential theory for most of the cycle; (ii) for

$5< KC<8$

, the flow field is increasingly asymmetric but with frequent switching of the side associated with vortex shedding; and (iii) for

$KC\geq 8$

, the flow field is consistently asymmetric due to vortex shedding. The in-line force increases when the cylinder is near the wall due to dynamic pressures associated with pumping. This increase can be estimated using potential theory superimposed onto the force time history for an isolated cylinder at the same

$KC$

and

$Re$

. This study complements recent numerical modelling focused on low Reynolds number conditions and provides important insights into the fluid mechanics associated with trenching beneath cable and pipeline risers.
The “Rediscovery” of Reginald Ford and his New Zealand Antarctic Lectures, 1905 to 1926
Authors: Roche Michael 
Published: November 2022

AbstractReginald Ford, steward on Scott’sDiscoveryexpedition, settled in New Zealand in 1905 and over the next two decades gave public lectures about his Antarctic experiences. Hitherto unrelated biographical details of Ford’s early life are assembled, and something of the character of his lantern slide lectures are reconstructed from various sources. The means by which Ford established his authority as a public speaker included his actual participation in the events he lectured about, his credentialling as a Fellow of the Royal Geographical Society, and the use of his own lantern slides. The “performative triangle” established around the audience, the lantern slide images, and Ford as lecturer, is examined via contemporary newspaper accounts and Ford’s other writings.
A new way to identify if variation in children’s input could be developmentally meaningful: Using computational cognitive modeling to assess input across socio-economic status for syntactic islands
Authors: PEARL Lisa , BATES Alandi 
Published: November 2022

AbstractWhile there are always differences in children’s input, it is unclear how often these differences impact language development – that is, are developmentally meaningful – and why they do (or do not) do so. We describe a new approach using computational cognitive modeling that links children’s input to predicted language development outcomes, and can identify if input differences are potentially developmentally meaningful. We use this approach to investigate if there is developmentally-meaningful input variation across socio-economic status (SES) with respect to the complex syntactic knowledge called syntactic islands. We focus on four island types with available data about the target linguistic behavior. Despite several measurable input differences for syntactic island input across SES, our model predicts this variation not to be developmentally meaningful: it predicts no differences in the syntactic island knowledge that can be learned from that input. We discuss implications for language development variability across SES.
Emotional factors of early vocabulary in Spanish as a second language
Authors: Hernández Muñoz Natividad , Blanco Canales Ana 
Published: November 2022

AbstractPrevious studies analysing the differences in emotionality in first and second language suggest that affective content of lexical items is modulated in certain contexts. This paper investigates the differences in valence and arousal ratings for 300 early words, in both oral and written modalities, through speakers’ subjective appraisal of words given by two immersion groups of Spanish late bilinguals (Chinese and European) compared with a group of native speakers. The main goal of our study is to identify the lexical areas where variability occurs, regarding to a set of affective (emotional charge and intensity), grammatical (nouns, adjectives and verbs) and semantic (concreteness) features of words. Our results show that valence is the dimension where the greatest variability is observed between native and bilinguals, although the influence of the independent factors differs considerably. Besides, arousal yields illuminating data regarding the grammatical category of words and differentiation between the groups of participants.

Published: November 2022

Abstract:
This is the third article within a three-part series on Fourier ptychography, which is a computational microscopy technique for high-resolution, large field-of-view imaging. While the previous articles introduced the working principles of the technique, in this article we focus on the practical benefits that it brings to the imaging community. We present a didactic overview of the most important and well-established practical use-cases such as gigapixel imaging, quantitative phase contrast, thick sample imaging, and aberration metrology. We also discuss how Fourier ptychography can leave the visible light domain and venture into the realm of smaller wavelengths such as X-rays and electrons, among other topics.
When More is More: Do Non-Restricted Goals Benefit Employers and the Environment Too?
Authors: Patrasc-Lungu Adelaida , Iliescu Dragoș 
Published: November 2022

AbstractPrior research on goal self-concordance (GSC) and goal attainment (GA) has studied these dimensions as transversal sections through a person’s life domains. Blending the recent developments in self-determination theory and pro-environmental behavior literature, the current study introduced the concept of non-restricted goals and explored whether work climate (WCQ) and environmental identity (EID) impact GA and, through it, in-role job performance (IRB), organizational citizenship behaviors (OCB) and wellbeing, as well as organizational citizenship behaviors for the environment (OCBE). It also explored GSC along with basic psychological needs’ satisfaction (BPNS) and GA, as explanatory mechanisms. The study relied on data collected at two different moments in time, with a retained sample of 201 employees from different organizations. Results confirmed that WCQ and EID are relevant antecedents for IRB, OCB and wellbeing, as well as OCBE. Except for the direct relationship between EID and OCB/OCBE, most of these impacts were indirect, through BPNS, GSC or GA. The current study did not find a significant relationship between GSC and GA, adding to the line of mixed results regarding their relationship. The findings inform pro-environmental interventions in the workplace, as well as human resource management practices that foster employee wellbeing, work-life balance, and job performance.
Meltwater Lenses Over the Chukchi and the Beaufort Seas During Summer 2019: From In Situ to Synoptic View

Published: November 2022

AbstractWe investigate the Chukchi and the Beaufort seas in the Arctic Ocean, where salty and warm Pacific Water flows in through the Bering Strait and interacts with the sea ice, contributing to its summer melt. Thanks to in situ measurements recorded by two saildrones deployed during summer 2019 and to refined sea ice filtering in satellite L‐band radiometric data, we demonstrate the ability of satellite sea surface salinity (SSS) observed by Soil Moisture and Ocean Salinity and Soil Moisture Active and Passive to capture SSS freshening induced by sea ice melt. We refer to these freshening events as meltwater lenses (MWL). The largest MWL observed by the saildrones during this period occupied a large part of the Chukchi shelf, with a SSS freshening reaching −5 practical salinity scale, persisting for up to 1 month. This MWL restricted the transfer of air‐sea momentum to the upper ocean, as illustrated by measured wind speed and vertical profiles of currents. With satellite‐based sea surface temperature, satellite SSS provides a monitoring of the different water masses encountered in the region during summer 2019. Using sea ice concentration and estimated Ekman transport, we analyze the spatial variability of sea surface properties after the sea ice edge retreat over the Chukchi and the Beaufort seas. The two MWL captured by the saildrones and the satellite measurements resulted from different dynamics. Over the Beaufort Sea, the MWL evolution followed the meridional sea ice retreat whereas, in the Chukchi Sea, a large persisting MWL was generated by advection and subsequent melting of a sea ice filament.
What Can Hydrography Between the New England Slope, Bermuda and Africa Tell us About the Strength of the AMOC Over the Last 90 years?
Authors: Rossby T. , Palter J. , Donohue K. 
Published: November 2022

AbstractThe Gulf Stream is the only pathway in the subtropical North Atlantic by which warm water flows poleward. This transport of warm water and return of cold water at depth is called the Atlantic Meridional Overturning Circulation (AMOC). The dynamic method is applied to hydrocasts collected since the 1930s to estimate upper‐ocean transport (0–1,000 m) between the U.S. Continental Slope and Bermuda and separately to Africa with focus on the longest directly observable timescale. Calculating transport between the Slope and Bermuda eliminates the Gulf Stream's northern and southern recirculation gyres, while calculations between the Slope and Africa remove all other recirculating geostrophic flow. The net Slope‐Bermuda upper‐ocean transport is estimated to be 41.1 ± 0.4 Sv, decreasing by 2.0 ± 0.8 Sv between 1930 and 2020. The AMOC contribution is 18.4 ± 0.6 Sv, decreasing by 0.4 ± 0.6 Sv between 1930 and 2020.
Uncertainty in Reconstructing Paleo‐Elevation of the Antarctic Ice Sheet From Temperature‐Sensitive Ice Core Records
Authors: Badgeley J. A. , Steig E. J. , Dütsch M. 
Published: November 2022

AbstractPaleotemperature reconstructions from ice cores are mixed signals of changes in climate and ice‐surface elevation. A common, temperature‐based paleoaltimetry method suggests these signals can be disentangled by comparing two proxy locations with similar climates. The difference between the records is assumed to be due to elevation, which is estimated by scaling the temperature difference by a lapse rate. We investigate the uncertainty associated with this approach using a case study of the Antarctic Ice Sheet during the Last Glacial Maximum. From an ensemble of climate simulations, we extract modeled temperatures at locations of real ice cores. We find uncertainty on the order of hundreds of meters that results from spatial heterogeneity in non‐adiabatic temperature change, which itself stems in part from elevation‐induced atmospheric circulation change. Our findings suggest that caution is needed when interpreting temperature‐based paleoaltimetry results for ice sheets.
Non‐Linear Response of the Extratropics to Tropical Climate Variability
Authors: Walsh A. , Screen J. A. , Scaife A. A. , Smith D. M. 
Published: November 2022

AbstractThere are established El Niño‐Southern Oscillation (ENSO) and Quasi‐biennial Oscillation (QBO) teleconnections to the extratropics that alter the strength of the polar vortex. Here, we demonstrate non‐linearity in the stratospheric polar vortex response to ENSO and QBO combined, in climate model simulations and observational data. We show that the combined effect of El Niño and QBO easterly phase (QBO‐E) on the polar vortex is greater than the linear combination of the individual responses to El Niño and QBO‐E separately. Observations support the model results, despite a relatively small sample of observed cases. We propose that non‐linearity in the teleconnection to ENSO and QBO is caused by the combined effects of an increase in wave driving from El Niño and more poleward propagation of wave activity during QBO‐E. Our results have implications for extreme winters when both El Niño and QBO‐E are active.

Published: November 2022

AbstractLower atmospheric gravity waves (GWs) can significantly impact waves in the middle and upper atmospheres and are vital for turbulence generation. This paper puts the spotlight on the spatial–temporal variability of tropospheric GW total energy (ET) and its potential sources above four regions of interest (ROIs) gathered from high‐resolution radiosonde observations from the China Radiosonde Network during the years 2016–2019. The seasonality of ET above four ROIs shows different characteristics and is dependent on latitudes and underlying terrains, reaching its maximum identified in the winter at middle latitudes. Interestingly, the annual cycles of the maximal ET shift from 35°N in October to 25°N in March of the next year, triggered by the shift in the winter subtropical jet. Based on the random forests regressor, the jet stream between 200 and 125 hPa likely serves as the primary source for the observed GWs above the ROIs with low and middle latitudes, with relative contributions of around 60%. However, the Kelvin–Helmholtz instability between 800 and 125 hPa could be the most recognized source of GWs and contributes around 68.4% to the observed energy. During the rainy season, the ET under scenarios of convective precipitation is around 20% larger than the other. As well, as the near‐surface or low‐level wind interacts with a mountain barrier over the Tibetan Plateau region, 12.4% of the observed ET is attributed to the strength of the low‐level wind.

AbstractAs a crucial variable in hydrological and climate modeling, a lot of efforts have been made to estimate the evaporation (E, including soil evaporation, canopy interception, and plant transpiration) on the Tibetan Plateau (TP). Most studies showed that the evaporation on the TP stops increasing or even decreases in the recent two decades. However, the spatio‐temporal variability of this phenomenon and its underlying mechanism remains uncertain. Here, we utilized a state‐of‐the‐art version of the sigmoid generalized complementary equation to estimate the monthly evaporation over the TP for the period of 1979–2018. The results show that the annual E increases significantly during 1979–1998 with a rate of 1.94 mm yr−1 (based on the total E over the TP), however, it decreases during 1999–2018 with a rate of −1.06 mm yr−1. The most significant decreasing trend of E occurs in the spring. The areas with the most significant decrement of E include the central and western Qiangtang Plateau, the middle reaches of Yarlung Zangbo River, and the Yangtze River basin. By introducing a new aridity index Rwe, we identified that the decrement of E mainly occurs in the water‐limited regions, which contribute to 60% of the total decreasing trend of the whole region; at the same time, the energy‐limited regions also contribute to 40% of the decreasing trend. This study is important for the hydrological researches and decision making because the trend of E can influence the water resources and agriculture.
