AbstractThe green turtle Chelonia mydas is a large marine turtle present in tropical and subtropical seas of the Atlantic, Pacific and Indian Oceans. It is categorized as Endangered on the IUCN Red List based on the trend of nesting populations at 32 sites, of which only three are in the Pacific Ocean. New Caledonia is a sui generis overseas territory of France in the south-west Pacific Ocean c. 1,210 km east of Australia. The presence of green turtles in New Caledonian waters is known, although the main nesting sites are far from the main island, on remote uninhabited islands. Since 1988 field missions to these remote reefs, namely d'Entrecasteaux, Bellona and Chesterfield, have collected data to quantify the nesting of green turtles in New Caledonia. For the first time we analyse the data collected during these missions. D'Entrecasteaux, Bellona and Chesterfield Reefs host a large nesting colony of green turtles, with the upper credible estimate of nesting activities reaching 150,000 nesting tracks in some years. These numbers exceed the estimated number of green turtle activities in the Pacific. The trend of the number of nesting activities is stable and has the same relationship with the Southern Oscillation Index as observed at Australian nesting sites. Our recommendations for the French authorities are to continue monitoring these populations, collect new demographic parameters and ensure the protection of these remote reefs, which should be considered a national treasure for New Caledonia.
Playing the fool: jesters of the Safavid and Zand courts
Authors: Izzo Gianni 
Published: August 2023

AbstractThis article looks at the history of jesters affiliated with the Iranian court during the Safavid and Zand periods. I present several case studies of jesters (dalqak), featuring Kal ʿEnāyat and Dalāleh Qezī from the Safavid period and Lūṭī Ṣāleḥ from the Zand period. From various primary resources including memoirs, European travelogues, and court-associated chronicles, I relate several accounts associated with these personalities and describe their unique relationship with the ruling shāh of their time. Through various staged and spontaneous performances involving irony, subterfuge, and satire, jesters – as embodied “mirrors for princes” – demonstrate the inherent precarity of the shāh's rule and the need to be accountable to his subjects. In comparing the Safavid jester to others across time and place, the performative simulation of transcending the status quo's gender, class, political, and moralistic boundaries will be shown to help preserve them.
Worst-case Omega ratio under distribution uncertainty with its application in robust portfolio selection
Authors: Li Qiuyang , Xie Xinqiao 
Published: August 2023

AbstractOmega ratio, a risk-return performance measure, is defined as the ratio of the expected upside deviation of return to the expected downside deviation of return from a predetermined threshold described by an investor. Motivated by finding a solution protected against sampling errors, in this paper, we focus on the worst-case Omega ratio under distributional uncertainty and its application to robust portfolio selection. The main idea is to deal with optimization problems with all uncertain parameters within an uncertainty set. The uncertainty set of the distribution of returns given characteristic information, including the first two orders of moments and the Wasserstein distance, can handle data problems with uncertainty while making the calculation feasible.

AbstractBackground:Timely prenatal diagnosis of CHD allows families to participate in complex decisions and plan for the care of their child. This study sought to investigate whether timing of initial fetal echocardiogram and the characteristics of fetal counselling were impacted by parental socio-economic factors.Methods:Retrospective chart review of fetal cardiac patients from 1 January, 2017 to 31 December, 2018. We reviewed gestational age at first fetal echo, maternal age and ethnicity, zip code, rurality index, and hospital distance. Counselling was evaluated based on documentation regarding use of interpreter, time billed for counselling, and treatment option chosen.Results:Total of 139 maternal–fetal dyads were included, and 29 dyads had single-ventricle heart disease. There was no difference in income, hospital distance or rurality index, and first fetal echo timing. There was no significant difference between maternal ethnicity and maternal age, gestational age at initial visit, or follow-up. Patients in rural areas had increased counselling time (p < .05). There was no difference between socio-economic factors and ultimate parental choices (termination, palliative delivery, or cardiac interventions).Conclusion:Oregon comprises a heterogeneous population from a large geographical catchment. While prenatal counselling and family decision-making are multifaceted, we demonstrated that dyads were referred from across the state and received care in a uniformly timely manner, and once at our centre received consistent counselling despite differences in parental socio-economic factors.

Published: August 2023

AbstractObjectivesAccurate prognostic understanding among patients with advanced cancer and their caregivers is associated with greater engagement in advance care planning (ACP) and receipt of goal-concordant care. Poor prognostic understanding is more prevalent among racial and ethnic minority patients. The purpose of this study was to examine the feasibility, acceptability, and impact of a patient–caregiver communication-based intervention to improve prognostic understanding, engagement in ACP, and completion of advance directives among a racially and ethnically diverse, urban sample of patients and their caregivers.MethodsPatients with advanced cancer and their caregivers (n = 22 dyads) completed assessments of prognostic understanding, engagement in ACP, and completion of advance directives at baseline and post-intervention, Talking About Cancer (TAC). TAC is a 7-session intervention delivered remotely by licensed social workers that includes distress management and communication skills, review of prognosis, and information on ACP.ResultsTAC met a priori benchmarks for feasibility, acceptability, and fidelity. Prognostic understanding and engagement in ACP did not change over time. However, patients showed increases in completion of advance directives.Significance of resultsTAC was feasible, acceptable, and delivered with high fidelity. Involvement of caregivers in TAC may provide added layers of support to patients facing advanced cancer diagnoses, especially among racial and ethnic minorities. Trends indicated greater completion of advance directives but not in prognostic understanding or engagement in ACP. Future research is needed to optimize the intervention to improve acceptability, tailor to diverse patient populations, and examine the efficacy of TAC in a randomized controlled trial.

Published: August 2023

AbstractObjectivesTo explore the perceptions of parents caring for a child with a life-limiting condition on approaches to communication used by clinicians engaging in routine serious illness communication.MethodsAn exploratory qualitative design was used, employing a thematic analysis of data derived through semi-structured interviews which presented hypothetical vignettes of serious illness conversations to elicit parental perspectives. Adult parents of children with a life-limiting condition, in a stable phase of care, known to the Neurodevelopment and Disability Department of a tertiary Children’s Hospital in Melbourne, Australia, were purposively sampled to achieve a broad representation of relevant clinical and sociodemographic factors.ResultsEleven parents (72% female) of children aged 7 months to 18 years participated. Two major themes characterized parental perspectives on serious illness communication: “Approaches clinicians can use to lay the foundation for quality communication” including checking in, validation, aligning with hopes and a commitment to listening and being present; and “Approaches clinicians can use to aid the delivery of information” including honesty and compassion, presenting possibilities, providing a plan, and conveying the clinician’s experience.Significance of resultsThis study provides novel insights into the perspectives of parents of children with life-limiting conditions that inform how clinicians may best approach serious illness communication. The findings highlight the need for clinicians working in pediatric health care to be cognizant of parents’ needs before and during conversations. Laying the foundation for quality communication is important alongside the approaches outlined that aid in the delivery of information.

AbstractThe advancement in wireless communication is fueling the growth of innovative antenna array designs toward cost-effective and performance-oriented solutions. This paper proposed unconventional methods to design antenna arrays for multi-pattern synthesis without using attenuators or phase shifters. A low-cost alternative is proposed with “Time-modulation”-based antenna array capable of electronic scanning and beam steering. Here, “Time” is utilized as a fourth-dimensional (4D) array parameter, and that is why “Time-modulated” arrays are also called as 4D antenna arrays. The idea is to control the high-speed switch attached with each antenna periodically to produce desirable current and phase tapering. This article expanded the “Time-modulation” concept to synthesize multiple radiation patterns like monopulse patterns, scanned beam patterns, shaped beam patterns, and cosecant-squared beam patterns for multifunctional radar systems. Suitable time schemes are developed to generate the narrowband sum–difference patterns useful for monopulse radars. Simultaneous scanned beam patterns are also proposed for narrowband communication. Furthermore, to address the wideband applications, shaped flat-top beam patterns and cosecant-squared beam patterns are also proposed. In this regard, 20- and 16-element “Time-modulated” linear array antennas are developed, and the parameters of the arrays are controlled by suitably designed objective functions with quasi-Newton method (QNM)-based memetic optimization method. For this purpose, first a well-known genetic algorithm is adopted to search the potential trust regions in the exploration stage and QNM is used for fine-tuning. Furthermore, the Broyden’s good method-based direction-updating equation is used with QNM to improve the performance.
Non‐Radiative Effect of Land Use/Land Cover Differences on Land Surface Temperature Simulated by Noah‐MP Land Surface Model Over East Asia

AbstractBiophysical effects of land cover changes on land surface temperature (Ts), including two effects, that is, radiative effects (caused by surface albedo changes) versus non‐radiative effects (caused by changes in the energy flux distribution), have attracted the attention of many researchers. However, the uncertainties of land use and land cover (LULC) and vegetation schemes on non‐radiative effects, and the roles of non‐radiative effects on Ts, remain uncertain. In this study, we investigate the local impact of LULC differences by comparing Noah with multiparameterization (Noah‐MP) land model simulations with different LULC data sets and those with vegetation schemes whether they include interactive canopies. We attribute Ts changes induced by LULC differences obtained from Noah‐MP simulations to radiative and non‐radiative effects over East Asia based on the decomposed temperature metric theory. The results indicate that vegetation cools Ts over urban regions by 4.0–6.0°C. Grassland and cropland decrease the Ts over barren regions. Forests are warmer (cooler) than grassland and cropland in high latitudes (in mid and low latitudes). Grassland is cooler than cropland. However, the magnitude of Ts changes induced by these differences is lower than that induced by differences between vegetation and urban. The non‐radiative effect generally explains more than 50% of the local changes in Ts. The interactive canopies enlarge Ts changes for afforestation or replacements of urban region by vegetation. The effect of uncertainties in LULC data sets is negligible. This study highlights the importance of non‐radiative biophysical effects and interactive canopies on local changes in Ts.
Evidence of Abrupt Transitions Between Sea Ice Dynamical Regimes in the East Greenland Marginal Ice Zone

Published: August 2023

AbstractSea ice modulates the energy exchange between the atmosphere and the ocean through its kinematics. Marginal ice zone (MIZ) dynamics are complex and are not well resolved in routine observations. Here, we investigate sea ice dynamics in the Greenland Sea MIZ using in situ and remote sensing Lagrangian drift datasets. These datasets provide a unique view into ice dynamics spanning spatial scales. We find evidence of tidal currents strongly affecting sub‐daily ice motion. Velocity anomalies show abrupt transitions aligned with gradients in seafloor topography, indicating changes in ocean currents. Remote‐sensed ice floe trajectories derived from moderate resolution satellite imagery provide a view of small‐scale variability across the Greenland continental shelf. Ice floe trajectories reveal a west‐east increasing velocity gradient imposed by the East Greenland Current, with maximum velocities aligned along the continental shelf edge. These results highlight the importance of small scale ocean variability for ice dynamics in the MIZ.

Published: August 2023

AbstractStream gauging stations provide critical streamflow measurements for hydrological applications; however, they may not accurately capture total catchment discharge due to unmonitored regional groundwater flow. Here, we evaluate the effectiveness of streamflow data from gauging stations worldwide to represent total catchment discharge through a modified hydrological model that includes baseflow signatures to constrain groundwater flow processes. We find that approximately 70% of gauging stations present biased estimations of total catchment discharge (bias >10%). This result implies that hydrology‐related processes may not be fully understood, and misleading conclusions may be drawn owing to the low streamflow measurement effectiveness. By influencing subsurface hydrological processes, catchment factors, including catchment area, topography, climate, and geological features, are linked to the effectiveness of streamflow measurements. Our findings highlight the importance of accurate streamflow measurement effectiveness for obtaining a reliable understanding of catchment hydrological processes to support sustainable water resource management.

Published: August 2023

AbstractThe amount, frequency and intensity of extreme precipitation over Xinjiang have increased dramatically under the wetting trend in Northwest China, but long‐term trends in the precipitation‐recycling process remain largely unexplored. Based on dynamic recycling model and MERRA2 reanalysis, we revealed a mean recycling ratio for extreme precipitation in Xinjiang of 42.3% with a growth rate of 2.3% decade−1 during 1982–2019. The increasing trend of extreme precipitation was almost equally attributed to increased recycling precipitation (49%) and external precipitation (51%). The extreme precipitation in Xinjiang exhibited two peak centers, the Tianshan Mountains region (TS) and Kunlun Mountains region (KL), highlighting variations in the water cycle. Specifically, the external cycle predominated the increased extreme precipitation in TS (61%), while the recycling process mainly influenced the increase in KL (67%) due to markedly enhanced evapotranspiration. Moisture source attribution further proved the crucial role of evapotranspiration from Xinjiang and its vicinity in extreme precipitation.
Interaction of Cloud Dynamics and Microphysics During the Rapid Intensification of Super‐Typhoon Nanmadol (2022) Based on Multi‐Satellite Observations
Authors: Wu Zuhang , Zhang Yun , Zhang Lifeng , Zheng Hepeng 
Published: August 2023

AbstractUsing multi‐satellite observations, the cloud dynamic and microphysical characteristics were revealed during the rapid intensification (RI) of super‐typhoon Nanmadol (2022). As the storm intensifies, the eyewall contracts, the upper‐level divergence strengthens, and the cirrus cloud increases, leading to stronger upper‐level radial outflow and the vertical updraft. Meanwhile, it is found that there exists a dynamically attractive area in the outer rainbands, where particles grow effectively and form “a small amount of large particles” around 300 km from the eye. A theory of cloud dynamics‐microphysics interaction, called “tunnel theory,” is further proposed to explain the generation, accumulation, and concentrated downflow of large particles in the outer rainbands during RI. Results suggest the unique feature of particle distribution in the outer rainbands could be a potential indicator for RI.
Climate‐Induced Decadal Ocean Wave Height Variability From Microseisms: 1931–2021
Authors: Bromirski Peter D. 
Published: August 2023

AbstractLong‐term coastal wave climate changes under global warming cannot be reliably assessed from relatively short duration buoy significant wave height (Hs) observations that began about 1980. Alternatively, microseisms at double the wave frequency (DFM) provide proxy records of near‐coastal wave activity. An empirical wave reconstruction methodology transforms DFM from UC Berkeley seismic station BKS to seismic Hs (sHs). Broadband digital seismic observations since 1992 at BKS provide DFM reference spectral levels. Earlier digitized archived BKS seismogram DFM levels are adjusted to give spectral levels that are consistent with current observations, yielding a combined 90‐year sHs record for winters (November–March) spanning the 1931–2021 epoch. Mean winter sHs derived from digitized 1980s seismograms are well‐correlated with nearby buoy Hs. Comparison of deep‐water extreme Hs with sHs demonstrates that sHs is dominated by near‐coastal wave activity. Much greater decadal and interannual variability occurred during the 1931–1970 epoch, including extended periods of exceptionally low sHs during 1939–1947 and 1957–1965 that have not occurred since global warming accelerated near 1970, suggesting that winter extratropical storm intensity has generally increased. Comparisons of winter sHs variability with anomalous sea level pressure (SLPa) patterns across the North Pacific demonstrate the association of coastal sHs with broad‐scale atmospheric variability, with differences between long‐term averages of winter SLPa indicating an Aleutian Low intensification, consistent with both increased mean sHs and occurrence of extreme events since 1970. Recent record global annual temperatures suggest that warming may be accelerating, resulting in stronger storms that intimates further increased winter Hs may be forthcoming.
Reversing pancreatic β-cell dedifferentiation in the treatment of type 2 diabetes
Authors: Son Jinsook , Accili Domenico 
Published: August 2023

AbstractThe maintenance of glucose homeostasis is fundamental for survival and health. Diabetes develops when glucose homeostasis fails. Type 2 diabetes (T2D) is characterized by insulin resistance and pancreatic β-cell failure. The failure of β-cells to compensate for insulin resistance results in hyperglycemia, which in turn drives altered lipid metabolism and β-cell failure. Thus, insulin secretion by pancreatic β-cells is a primary component of glucose homeostasis. Impaired β-cell function and reduced β-cell mass are found in diabetes. Both features stem from a failure to maintain β-cell identity, which causes β-cells to dedifferentiate into nonfunctional endocrine progenitor-like cells or to trans-differentiate into other endocrine cell types. In this regard, one of the key issues in achieving disease modification is how to reestablish β-cell identity. In this review, we focus on the causes and implications of β-cell failure, as well as its potential reversibility as a T2D treatment.

AbstractAutophagy functions in cellular quality control and metabolic regulation. Dysregulation of autophagy is one of the major pathogenic factors contributing to the progression of nonalcoholic fatty liver disease (NAFLD). Autophagy is involved in the breakdown of intracellular lipids and the maintenance of healthy mitochondria in NAFLD. However, the mechanisms underlying autophagy dysregulation in NAFLD remain unclear. Here, we demonstrate that the hepatic expression level of Thrap3 was significantly increased in NAFLD conditions. Liver-specific Thrap3 knockout improved lipid accumulation and metabolic properties in a high-fat diet (HFD)-induced NAFLD model. Furthermore, Thrap3 deficiency enhanced autophagy and mitochondrial function. Interestingly, Thrap3 knockout increased the cytosolic translocation of AMPK from the nucleus and enhanced its activation through physical interaction. The translocation of AMPK was regulated by direct binding with AMPK and the C-terminal domain of Thrap3. Our results indicate a role for Thrap3 in NAFLD progression and suggest that Thrap3 is a potential target for NAFLD treatment.
