Authors: Ghahramani Maral , Javanbakht Mehran , Jamalpour Seifollah , Hamidi Susan 
Published: March 2023

In this work, a facile and accurate method is reported for the delocalization of negative charge on fluorinated polymers to obtain high-performance single-ion conducting polymer electrolytes (SICPs) based on brush copolymers with simultaneous high ionic conductivity and tLi+. The poly(styrene sulfonate) (PSSA) single ion-conducting moieties were grafted-from C–F linkages to the fluorinated polymer’s backbone via the atom transfer radical polymerization method. The chemical structure characterization of the synthesized brush copolymers via 1H-NMR and thermal gravimetric analyses (TGA) confirmed 25% grafting of PSSA to the poly(vinylidene fluoride) backbone. In continue, the pristine and single-ion fluorinated polymer membranes with bi-continuous honeycomb-like morphology structures were prepared via the vapor-induced phase inversion (VIPS) method. After immersing in a liquid electrolyte, the prepared SICP demonstrated promising ionic conductivity (σ), t

Li+
, and electrochemical stability of 1.9 × 10−3 Scm−1, 0.82, and 5.2 V (vs Li+/Li), respectively. The assembled Li/SICP/LiMn2O4 half-cells revealed an improved discharge capacity of 168 mA hg−1 at 0.1C. The charge-discharge studies revealed that the ohmic-resistance and polarization resistance of fluorinated polymer electrolytes could be decreased by the effect of PSSA-grafted moieties. The results of this work confirmed the promising capability of these new SICPs for high-safety LIBs.

The aim of this study was to optimize the formulation of hard candy with antiviral herbal extracts and flowered with Citrus limon peel essential oils. To substitute water fraction, the D-optimal mixture design was used. The optimized mixture fractions of the best hard candy formulation contain Curcuma longa extract (10%), Artemisia herba-alba Asso extract (3.33%), Glycyrrhiza glabra extract (1.66%), and Zingiber officinale extract (1.66%) and flowered by 20 μL/100 gram of Citrus limon essential oils. The effect of the addition had been investigated on the sensory, physicochemical, and phytochemical of the hard candy according to the optimal formulation. The main component of Citrus limon essential oil is limonene (52.47%), which has a pleasant lemon fragrance. The mixture of herbal extract added increased the total phenols, the flavonoid, and the ash content of the formulated hard candy (

Stops and Starts
Authors: Nudler Alicia 
Published: March 2023

Abstract
This article examines Samuel Beckett’s play Krapp’s Last Tape in the context of Argentinian post-dictatorship theatre. I offer a brief history of Beckett’s influence on theatre in Argentina together with a summary of the performance history of his plays, and I reflect on the ways in which they have been interpreted in Argentina’s recent history. This contextualization enables me to focus on the figure of Krapp and discuss the stops and starts that Krapp performs while playing and recording his tapes. By examining Krapp’s archive, the article engages in a discussion about individual and collective memory: I draw attention to the play’s resonances in relation to the political processes unfolding in Argentina today, where archives are of vital importance in recovering from the social trauma of the last dictatorship.
The Distribution of Land Rights in Huaibei from the Republican Period to the Early Years of the People’s Republic of China: A Case Study Based on the Suixi County Archives
Authors: Yang (杨金客) Jinke 
Published: March 2023

Abstract
It was once believed that land rights in the Huaibei region were highly concentrated and that large ownership of land was extremely common. However, in recent years, more and more scholars have come to believe that there was no such tendency of serious land concentration in modern China. Republican-era statistics on land ownership in Huaibei are extremely rare. In contrast, the “Land and Real Estate Ownership Certificate Stubs” 土地房产所有证存根 collected by the Suixi County Archives in the early years of the People’s Republic provide detailed records on the land ownership distribution in this county. Using these materials, we calculate the Gini coefficient of land ownership distribution for each village. It turns out that most of the villages had a Gini coefficient lower than 0.35, which indicates only a moderate differentiation of land occupation. It shows that large landownership did not prevail in rural Suixi. Rather, it was a world of small-scale landowners.
A Novel Mechanism for Extreme El Niño Events: Interactions between Tropical Cyclones in the Western North Pacific and Sea Surface Warming in the Eastern Tropical Pacific
Authors: Tong Bo , Wang Xin , Wang Dongxiao , Zhou Wen 
Published: March 2023

Abstract
This study presents a novel mechanism for the generation of extreme El Niño events by analyzing interactions between tropical cyclones (TCs) in the western North Pacific (WNP) in spring [March–May (MAM)] and summer [June–August (JJA)] and sea surface warming in the eastern tropical Pacific. It is suggested that anomalously strong TCs in the WNP in MAM and JJA are essential for the formation of extreme El Niño events. MAM TCs excite considerable westerly wind bursts (WWBs) and facilitate the generation of El Niño events in late spring. The sea surface temperature (SST) in the central-eastern tropical Pacific increases prominently during the following summer, which is due to the warm water carried by downwelling Kelvin waves induced by the anomalous westerlies in the western tropical Pacific associated with the WNP TCs, as well as the lessening cold water upwelling resulting from the deepening thermocline in the eastern tropical Pacific. The developing El Niño in turn contributes to the TC activities over the southeastern quadrant of the WNP in summer, characterized by a stronger intensity, higher frequency, and longer duration. The resulting JJA TC-induced westerlies could further enhance the eastern tropical Pacific warm SST anomalies, and thus an extreme El Niño event tends to appear in the following autumn and winter. These physical processes are verified by several sets of atmosphere–ocean coupled model experiments.

Significance Statement
Tropical cyclone activity is one of the most destructive phenomena in the world. Extreme El Niño events can also cause devastating climate disasters. Understanding the relationship between these two events can help with disaster forecasting and prevention. This study finds that TC activity in the western North Pacific contributes to the appearance of extreme El Niño events. Abnormally active TC activity in spring can cause strong near-equatorial westerly wind anomalies, eastward transport of warm water from the western tropical Pacific, and a deepening ocean thermocline in the east, resulting in the earlier onset of El Niño events. Influenced by the El Niño event, the TC activity in summer is strengthened, which in turn continues to promote the surface warming of the central-eastern tropical Pacific, eventually resulting in extreme event occurrence.
Sources of Uncertainty in the Time of Emergence of Tropical Pacific Climate Change Signal: Role of Internal Variability
Authors: Zhong Shuping , Ying Jun , Collins Matthew 
Published: March 2023

Abstract
Determining the time of emergence of anthropogenic climate change signals from natural variability, for both the tropical Pacific mean state and El Niño–Southern Oscillation (ENSO), are critical for early climate warning and adaptation planning. However, there remains considerable uncertainty in estimating those times of emergence in state-of-the-art climate models. In this study, the role of internal variability in the uncertainty of the times of emergence of tropical Pacific annual-mean sea surface temperature (SST) and rainfall, and ENSO-related SST and rainfall are investigated by using three large ensembles of model simulations under the historical and RCP8.5 emission scenarios, as well as the multimodel ensemble from phase 6 of the Coupled Model Intercomparison Project under the historical and SSP5–8.5 emission scenarios. Specific attention is paid to the eastern equatorial Pacific. It is found that internal variability contributes to less than half of the total uncertainty in both the times of emergence of annual-mean SST and rainfall in all the three large ensembles, with more contribution to the latter than to the former. Hence, model differences dominate. Conversely, internal variability contributes to a major part of the total uncertainty in the times of emergence of ENSO-related SST and rainfall in one large ensemble that has sufficient members to show emergent signals. These results imply that we could have a relatively high confidence in claiming that anthropogenic climate change has impacted the annual-mean state, if an emergent annual-mean signal is observed in the real world. However, in claiming changes in ENSO variability, the signal is easily obscured by internal variability.
Breaking of Internal Waves Parametrically Excited by Ageostrophic Anticyclonic Instability
Authors: Onuki Yohei , Joubaud Sylvain , Dauxois Thierry 
Published: March 2023

Abstract
A gradient-wind balanced flow with an elliptic streamline parametrically excites internal inertia-gravity waves through ageostrophic anticyclonic instability (AAI). This study numerically investigates the breaking of internal waves and the following turbulence generation resulting from the AAI. In our simulation, we periodically distort the calculation domain following the streamlines of an elliptic vortex and integrate the equations of motion using a Fourier spectral method. This technique enables us to exclude the overall structure of the large-scale vortex from the computation and concentrate on resolving the small-scale waves and turbulence. From a series of experiments, we identify two different scenarios of wave breaking conditioned on the magnitude of the instability growth rate scaled by the buoyancy frequency λ/N. First, when
, the primary wave amplitude excited by AAI quickly goes far beyond the overturning threshold and directly breaks. The resulting state is thus strongly nonlinear turbulence. Second, if
, weak wave–wave interactions begin to redistribute energy across frequency space before the primary wave reaches a breaking limit. Then, after a sufficiently long time, the system approaches a Garrett–Munk-like stationary spectrum, in which wave breaking occurs at finer vertical scales. Throughout the experimental conditions, the growth and decay time scales of the primary wave energy are well correlated. However, since the primary wave amplitude reaches a prescribed limit in one scenario but not in the other, the energy dissipation rates exhibit two types of scaling properties. This scaling classification has similarities and differences with D’Asaro and Lien’s wave–turbulence transition model.

Significance Statement
Due to the gradients in buoyancy and pressure, density-stratified seawater supports oscillatory vertical motion called internal waves. When waves significantly skew a density isosurface, dense water lifts over lighter water resulting in gravitational instability and high energy dissipation. In this wave-breaking process, seawater is vertically mixed, transporting heat and nutrients essential to maintain Earth’s climate and ecosystems. This study investigates the generation and breaking of ocean internal waves in a novel numerical simulation setup; we temporally distort the model shape to emulate the wave excitation forced by a larger-size horizontal eddy, a ubiquitous situation at O(1–10) km scales in the upper ocean. The simulation results exhibit two unique wave-breaking scenarios with distinct scaling features in turbulence energy dissipation rates.

Authors: Chen Shang-Xiong , Zhang Bin , Hao Ying-Xue , Xiao Hang 
Published: March 2023

This study compared the efficacy and safety of distal transradial access (dTRA) and common femoral artery access (CFA) for endovascular treatment of non-coronary arterial disease. 102 interventions were divided into dTRA ( n = 51) and CFA ( n = 51) groups; the puncture success rate was 100% in both groups. The mean number of punctures and puncture time were greater in the dTRA than CFA group (1.86 vs 1.04 and 3.96 vs ≤1.00 min, p < .001 for both), whereas the access-related complication rate was comparable. The surgical success rate was higher in the CFA than dTRA group (98.0 vs 84.3, p = .036), and the operative time was longer in the dTRA than CFA group (99.09 vs 84.10 min, p = .017). The postoperative adverse event rate was not different between the dTRA and CFA groups. dTRA is a safe and feasible access for non-coronary arterial disease and is comparable to CFA in terms of puncture success, access-related complications, and major adverse events. The dTRA is inferior to CFA in the treatment of lower extremity arterial disease. Due to the increase in the operation time and the contrast medium volume in the dTRA, it is necessary to be vigilant about contrast nephropathy and late radiological random side effects.
Effect of NH2-MWCNTs sprayed carbon fiber on the mechanical properties of carbon fiber reinforced polycarbonate composite for lightweight structural applications
Authors: Sasikumar R , Jayavel R 
Published: March 2023

In this work, amine-Multi-walled Carbon Nanotubes (MWCNTs) were reinforced on the surface of fiber fabric by solvent spray deposition method in order to improve the mechanical and thermal properties of carbon fiber/polycarbonate film (CF/PC) stacked composites. The hot press method was used to fabricate the CF/PC composites with varied NH2-MWCNTs concentrations of 0.1, 0.3, 0.5, and 0.7 wt.%, as well as the reference composite. The multifarious assembly features of Carbon nanotubes (CNTs) on the fiber surface exhibit greater interfacial mechanics and have a major influence on the load transfer efficiency of the composite. In comparison with reference CF/PC composite, the tensile strength (384.55 MPa) and modulus (23.78 GPa) of composites increase by 67% and 40% respectively for 0.1% NH2-MWCNT reinforcement, whereas flexural strength and flexural modulus increase by 98% and 80%. However, as compared to the 0.1% CNT reinforcement, the impact strength of the 0.7% increases over 6% by absorbing substantial fracture energy. The inclusion of MWCNTs lowers the glass transition temperature (Tg) of composites due to the role of molecular conformations in free surface volume of the polymer. X-ray Photoelectron spectroscopy (XPS) and FTIR analysis confirms the functional groups present in the nanocomposite. Field Emission Scanning electron microscopy (FESEM) was used to analyze the dispersion and adhesion surface morphology of MWCNTs on fiber and the fiber/matrix interface interaction fractograph of tensile and impact tested samples.

Published: March 2023

Background: Bipolar disorder (BD) is a clinical risk factor for Alzheimer’s disease (AD). Apolipoprotein E ε4 ( APOE ε4), a genetic risk factor for AD, has been associated with brain structure and neurocognition in healthy youth. Aims: We evaluated whether there was an association between APOE ε4 with neurostructure and neurocognition in youth with BD. Methods: Participants included 150 youth (78 BD:19 ε4-carriers, 72 controls:17 ε4-carriers). 3T-magnetic resonance imaging yielded measures of cortical thickness, surface area, and volume. Regions-of-interest (ROI) and vertex-wise analyses of the cortex were conducted. Neurocognitive tests of attention and working memory were examined. Results: Vertex-wise analyses revealed clusters with a diagnosis-by- APOE ε4 interaction effect for surface area ( p = 0.002) and volume ( p = 0.046) in pars triangularis (BD ε4 -carriers > BD noncarriers), and surface area ( p = 0.03) in superior frontal gyrus (controls ε4 -carriers > other groups). ROI analyses were not significant. A significant interaction effect for working memory ( p = 0.001) appeared to be driven by nominally poorer performance in BD ε4 -carriers but not control ε4 -carriers; however, post hoc contrasts were not significant. Conclusions: APOE ε4 was associated with larger neurostructural metrics in BD and controls, however, the regional association of APOE ε4 with neurostructure differed between groups. The role of APOE ε4 on neurodevelopmental processes is a plausible explanation for the observed differences. Future studies should evaluate the association of APOE ε4 with pars triangularis and its neurofunctional implications among youth with BD.
Is a Positive Intergenerational Workplace Climate Associated with Better Self-Perceived Aging and Workplace Outcomes? A Cross-Sectional Study of a Representative Sample of the Danish Working Population

Published: March 2023

The aim of this study was to determine the association between intergenerational workplace climate (attitudes, feelings, and perceptions about workers of different ages in the workplace) and self-perceived aging, work engagement, and turnover intention. A cross-sectional study was conducted via an online survey including answers from a representative sample of 1571 individuals aged 18–74 years, living and working in Denmark. In line with our hypotheses, we found that a more positive intergenerational workplace climate was related to a better self-perceived aging as well as to more work engagement and less turnover intention. In addition, we found that these associations were similar in all age groups. The findings point to the potential benefits of initiatives aimed at strengthening the intergenerational climate in workplaces.

Published: March 2023

Background Sufficient and timely spinal cord decompression is a critical surgical objective for neurological recovery in spinal cord injury (SCI). Residual cord compression may be associated with disturbed cerebrospinal fluid pressure (CSFP) dynamics. Objectives This study aims to assess whether intrathecal CSFP dynamics in SCI following surgical decompression are feasible and safe, and to explore the diagnostic utility. Methods Prospective cohort study. Bedside lumbar CSFP dynamics and cervical MRI were obtained following surgical decompression in N = 9 with mostly cervical acute-subacute SCI and N = 2 patients with non-traumatic SCI. CSFP measurements included mean CSFP, cardiac-driven CSFP peak-to-valley amplitudes (CSFPp), Valsalva maneuver, and Queckenstedt’s test (firm pressure on jugular veins, QT). From QT, proxies for cerebrospinal fluid pulsatility curve were calculated (ie, relative pulse pressure coefficient; RPPC-Q). CSFP metrics were compared to spine-healthy patients. computer tomography (CT)-myelography was done in 3/8 simultaneous to CSFP measurements. Results Mean age was 45 ± 9 years (range 17-67; 3F), SCI was complete (AIS A, N = 5) or incomplete (AIS B-D, N = 6). No adverse events related to CSFP assessments. CSFP rise during QT was induced in all patients [range 9.6-26.6 mmHg]. However, CSFPp was reduced in 3/11 (0.1-0.3 mmHg), and in 3/11 RPPC-Q was abnormal (0.01-0.05). Valsalva response was reduced in 8/11 (2.6-23.4 mmHg). CSFP dynamics corresponded to CT-myelography. Conclusions Comprehensive bedside lumbar CSFP dynamics in SCI following decompression are safe, feasible, and can reveal distinct patterns of residual spinal cord compression. Longitudinal studies are required to define critical thresholds of impaired CSFP dynamics that may impact neurological recovery and requiring surgical revisions.

Authors: Di Mascio Nicholas , McGrath Brid , Doran Ciara , Cashman James , Brennan Adrian , Flanagan Anne-Marie 
Published: March 2023

Background: Over the last two decades, many elective procedures have transitioned to day-case surgery thanks to the introduction of ‘enhanced recovery’ protocols. Only recently has total hip arthroplasty been considered a candidate for day-case surgery, as it was once associated with significant pain, mobility impairment and prolonged postoperative recovery. The National Orthopaedic Hospital Cappagh became the first public hospital in Ireland to set up a day-case total hip arthroplasty service in June 2018, and since then has performed over 109 such cases. Aims: We outline our day-case total hip arthroplasty pathway, with specific focus on anaesthetic considerations. We report rates of failed discharge and readmission Results: We achieved successful same-day discharge in 90.8% of our first 109 cases. Readmission rate was 4.6%. Conclusion: Our experience of implementing a day-case total hip arthroplasty pathway was highly positive and congruent with expectations from the literature. With appropriate patient selection and education, day-case total hip arthroplasty is not just safe, but of benefit to both patients and healthcare systems.
