Persistent impact of winter atmospheric circulation anomalies on Arctic sea ice

Published: September 2023

Abstract
According to previous studies, the Arctic Oscillation (AO) in winter has an impact on the evolution of sea ice conditions from winter until the following September. This study explores and compares the sea ice responses to two climatic modes of variability in the winter, the positive phase of the AO and the negative phase of the Arctic Dipole (AD) patterns. This study for the first time verifies that the AD-induced sea ice thickness change is comparable in magnitude to the AO-induced change by the end of the melting season. It proves that the negative AD in winter has a persistent impact on sea ice thickness comparable to the AO has. Furthermore, the AO and AD in the winter impact sea ice conditions in different ways. The AO cannot decrease sea ice thickness until the melting season. Most decreases in sea ice thickness are found over the Beaufort and Chukchi Seas starting in May. On the other hand, the negative AD mostly inhibits sea ice growth during the growing season thermodynamically over the Atlantic sector of the Arctic Ocean. The ensemble means of 22 CMIP6 models can reasonably catch the response of sea ice thickness change to the AO and AD in spatial distribution and temporal evolution. The CMIP6 model ensemble is better at reproducing the AD-induced response of sea ice than the AO-induced response, while the spread of results from individual models is extensive.
A unified approach to thermo-mechano-caloric-characterization of elastocaloric materials

Abstract
This paper presents a novel approach to characterizing the relevant mechanical, thermal and caloric properties of elastocalorics material in a single testing device. Usually, tensile experiments are performed to determine the rate- and process-depending stress/strain behavior of nickel-titanium-based shape memory alloys and potentially other elastocaloric materials made from metallic alloys. These tests are relevant for, e.g., characterization of hysteresis properties and subsequent calculation of mechanical work input. In addition, simultaneous observation with an infrared camera is useful to understand temperature evolution and maximum temperature changes achievable during the loading/unloading process. Characterization of the caloric properties of the materials determines latent heats and, together with the mechanical work, also the material coefficient of performance. It is typically carried out via differential scanning calorimetry (DSC), which is performed in a separate device and requires a second experiment with different types of samples. Furthermore, DSC measurements do not reflect the way mechanically induced phase transformations trigger the release and absorption of latent heats as it is the case for elastocalorics. In order to provide a more consistent understanding of the relevant elastocaloric material properties, we here present a novel method that (a) allows for a systematic determination of load-dependent latent heats and (b) introduces a comprehensive testing setup and suitable testing routine to determine the mechanical, thermal and caloric parameters in the same experimental device and with the same sample, thus greatly simplifying the overall procedure.

Abstract
Ammonia has been proposed to replace heavy fuel oil (HFO) in the shipping industry by 2050. When produced with low-carbon electricity, ammonia can reduce greenhouse gas emissions. However, ammonia emissions also contribute to local air pollution via the formation of secondary particulate matter. We estimate the potential ammonia emissions from storage and bunkering operations for shipping in Singapore, a port that accounts for 20% of global bunker fuel sales, and their impacts on air quality and health. Fuel storage and bunkering can increase total gaseous ammonia emissions in Singapore by up to a factor of four and contribute to a 25%–50% increase in ambient PM2.5 concentration compared to a baseline scenario with HFO, leading to an estimated 210–460 premature mortalities in Singapore (30%–70% higher than the baseline). Proper abatement on storage and bunkering can reduce these emissions and even improve ambient PM2.5 concentrations compared to the baseline. Overall, while an energy transition from HFO to ammonia in the shipping industry could reduce global greenhouse gas and air pollutant burdens, local policies will be important to avoid negative impacts on the communities living near its supply chain.

Published: September 2023

Abstract

Background and Aims
Submediterranean areas are rich ecotones, where slight modifications in environmental conditions can lead to substantial changes in the composition of plant communities. They thus offer an ideal scenario to examine plant community assembly. In this study, we followed a trait-based approach including intraspecific variability to elucidate (1) the relationship between niche occupancy components and species richness, (2) the processes governing the assembly of these communities and (3) the contribution of intraspecific trait variability in shaping the functional trait space.

Methods
We measured eight morphological and chemical traits in 405 individuals across 60 plots located in different forest communities (Mediterranean, Eurosiberian and Mixed) coexisting within a submediterranean ecosystem in central Spain. We calculated three niche occupancy components related to Hutchinson’s n-dimensional hypervolumes: the total functional volume of the community, the functional overlap between species within the community and the average functional volume per species, and then used null models to explore the relative importance of habitat filtering, limiting similarity and intraspecific variability as assembly patterns.

Key Results
Both habitat filtering and niche differentiation drive the community assembly of Mediterranean communities, whereas limiting similarity and hierarchical competition shape Eurosiberian communities. Intraspecific responses were mostly explained by shifts in species niches across the functional space (changes in the position of the centroids of hypervolumes).

Conclusions
Different assembly mechanisms govern the structure of Mediterranean, Eurosiberian and Mixed plant communities. Combining niche occupancy components with a null model approach at different spatial scales offers new insights into the mechanisms driving plant community assembly. Consideration of intraspecific variability is key for understanding the mechanisms governing species coexistence in species-rich ecotones.

Abstract

Aims
ST-segment elevation myocardial infarction complicated by cardiogenic shock (STEMICS) is associated with substantial mortality. As life expectancy increases, percutaneous coronary intervention (PCI) is being performed more frequently, even in elderly patients with acute myocardial infarction (AMI). This study sought to investigate the characteristics and impact of PCI on in-hospital mortality in patients with STEMICS.

Methods and results
The Japan AMI Registry (JAMIR) is a retrospective, nationwide, real-world database. Among 46 242 patients with AMI hospitalized in 2011–2016, 2760 patients with STEMICS (median age, 72 years) were studied. We compared 2396 (86.8%) patients who underwent PCI with 364 (13.2%) patients who did not. The percentage of mechanical circulatory support use in patients with STEMICS was 69.3% and in-hospital mortality was 34.6%. Compared with patients who did not undergo PCI, patients undergoing PCI were younger and had a higher rate of intra-aortic balloon pump use. A higher proportion was male or current smokers. In-hospital mortality was significantly lower in the PCI group than in the no-PCI group (31.3% vs. 56.0%, P &lt; 0.001). Percutaneous coronary intervention was independently associated with lower in-hospital mortality [adjusted odds ratio (OR), 0.508; 95% confidence interval (CI), 0.347–0.744]. In 789 (28.6%) patients aged ≥80 years, PCI was associated with fewer in-hospital cardiac deaths (adjusted OR, 0.524; 95% CI, 0.281–0.975), but was not associated with in-hospital mortality (adjusted OR, 0.564; 95% CI, 0.300–1.050).

Conclusion
In Japan, PCI was effective in reducing in-hospital cardiac death in elderly patients with STEMICS. Age alone should not preclude potentially beneficial invasive therapy.

Abstract
Long considered peripheral to both international affairs and the discipline of international relations (IR), Africa is increasingly at the center of global politics and academic debates. Global powers are competing for economic, political, and strategic influence on the continent, while Africa itself has emerged as an increasingly powerful and confident actor on the world stage. In large part, this is due to the leadership of the African Union (AU), which since its founding twenty years ago has embarked on an ambitious agenda inspired by Pan-Africanism, seeking to create an Africa that is a “Strong, United, and Influential Global Player.” Following the AU’s twentieth anniversary, this article and Special Forum situate the AU within recent debates in IR about non-Western agency and the contributions of the global South to world politics. Focusing on the role of the AU and Pan-African ideology in shaping Africa and its international engagements, we argue that an analysis of the AU and the influence of Pan-Africanism is crucial to an understanding of Africa’s actions and positions in contemporary world affairs. We conclude that the heightened geopolitical rivalry following Russia’s invasion of Ukraine threatens to undermine two key aspects of the AU’s Pan-Africanism, namely its commitment to democracy and human rights and its ambition to speak with a united voice on the world stage.

Abstract
Sterile alpha and Toll/interleukin receptor motif-containing protein 1 (SARM1) is a NAD+ hydrolase that plays a key role in axonal degeneration and neuronal cell death. We reported that c-Jun N-terminal kinase (JNK) activates SARM1 through phosphorylation at Ser-548. The importance of SARM1 phosphorylation in the pathological process of Parkinson’s disease (PD) has not been determined. We thus conducted the present study by using rotenone (an inducer of PD-like pathology) and neurons derived from induced pluripotent stem cells (iPSCs) from healthy donors and a patient with familial PD PARK2 (FPD2). The results showed that compared to the healthy neurons, FPD2 neurons were more vulnerable to rotenone-induced stress and had higher levels of SARM1 phosphorylation. Similar cellular events were obtained when we used PARK2-knockdown neurons derived from healthy donor iPSCs. These events in both types of PD-model neurons were suppressed in neurons treated with JNK inhibitors, Ca2+-signal inhibitors, or by a SARM1-knockdown procedure. The degenerative events were enhanced in neurons overexpressing wild-type SARM1 and conversely suppressed in neurons overexpressing the SARM1-S548A mutant. We also detected elevated SARM1 phosphorylation in the midbrain of PD-model mice. The results indicate that phosphorylated SARM1 plays an important role in the pathological process of rotenone-induced neurodegeneration.
Chronic Spontaneous Urticaria Following mRNA COVID-19 Booster Vaccination at a Military Academy
Authors: Miller Mechelle A , Raffetto Emily R , Lee Rachel U 
Published: September 2023

ABSTRACT
Several adverse cutaneous reactions have been reported in the literature after SARS-CoV-2 vaccination with emerging reports on chronic spontaneous urticaria (CSU). However, there is little literature of chronic urticaria after COVID-19 boosters in a military population and the impact on operational readiness. We present a retrospective case series of CSU following Moderna COVID-19 booster vaccinations at the US Naval Academy (USNA). Demographics, clinical features, and impact on readiness were evaluated. Forty-nine students from the USNA were evaluated for urticaria after their third COVID-19 booster vaccination. Seventeen individuals were diagnosed with CSU. The median age was 20 years and predominantly male; the median time interval between vaccination and the onset of urticaria was 11 days. Out of 13 referred to Allergy, 7 patients had CU index performed and 2 were positive. Four patients received a second booster vaccination subsequently and did not have any exacerbation of symptoms. Symptoms were controlled with antihistamines, and none required immunomodulator or immunosuppressive therapies. All students were able to complete their commissioning, and none were referred for a medical board. In this series, USNA students who developed CSU after the mRNA COVID-19 Moderna booster vaccine did not have limitations from commissioning, duty status, or issues with subsequent COVID-19 vaccinations.

Published: September 2023

Abstract

Background
Post-traumatic growth (PTG) has been extensively explored within general oncology, yet little is known about the experience of PTG in neuro-oncology. This study aimed to determine the representation of patients with primary brain tumors (PBT) in the PTG literature.

Methods
PsycINFO, PubMed, and CINAHL were systematically searched from inception to December 2022. Search terms were related to personal growth and positive reactions to cancer. Articles were first screened by titles and abstracts, then full texts were reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method.

Results
A total of 382 articles met the inclusion criteria. Of those, 13 included patients with PBT. Over 100 000 cancer patients were represented, with 0.79% having a PBT. Most research focused on low-grade gliomas. PTG negatively correlated with post-traumatic stress symptoms and avoidant coping. In the sole longitudinal study, patients with PBT demonstrated improved PTG after 1 year. Three quasi-experimental studies investigated the effect of mindfulness-based interventions with mixed-cancer samples and demonstrated improvement in PTG.

Conclusions
The inclusion rate of patients with PBT in the PTG literature was significantly lower than the population prevalence rate (1.3% of cancer diagnoses). Relatively few studies focused exclusively on how patients with PBT experience PTG (k = 5), and those that did only included low-grade glioma. The experience of PTG in those with high-grade glioma remains unknown. Patients with PBT are scarcely included in research on PTG interventions. Few studies examined the relationship between PTG and medical, cognitive, or psychological characteristics. Our understanding of the PTG experience in neuro-oncology remains extremely limited.

ABSTRACT
Superconducting phase transitions in two dimensions lie beyond the description of the Ginzburg-Landau symmetry-breaking paradigm for three-dimensional superconductors. They are Berezinskii-Kosterlitz-Thouless (BKT) transitions of paired-electron condensate driven by the unbinding of topological excitations, i.e. vortices. The recently discovered monolayers of layered high-transition-temperature (${{{T}}}_{{\rm C}}$) cuprate superconductor Bi2Sr2CaCu2O8+δ (Bi2212) meant that this 2D superconductor promised to be ideal for the study of unconventional superconductivity. But inhomogeneity posed challenges for distinguishing BKT physics from charge correlations in this material. Here, we utilize the phase sensitivity of scanning superconducting quantum interference device microscopy susceptometry to image the local magnetic response of underdoped Bi2212 from the monolayer to the bulk throughout its phase transition. The monolayer segregates into domains with independent phases at elevated temperatures below ${{{T}}}_{{\rm C}}$. Within a single domain, we find that the susceptibility oscillates with flux between diamagnetism and paramagnetism in a Fraunhofer-like pattern up to ${{{T}}}_{{\rm C}}$. The finite modulation period, as well as the broadening of the peaks when approaching ${{{T}}}_{{\rm C}}$ from below, suggests well-defined vortices that are increasingly screened by the dissociation of vortex-antivortex plasma through a BKT transition. In the multilayers, the susceptibility oscillation differs in a small temperature regime below ${{{T}}}_{{\rm C}}$, consistent with a dimensional crossover led by interlayer coupling. Serving as strong evidence for BKT transition in the bulk, we observe a sharp jump in phase stiffness and paramagnetism at small fields just below ${{{T}}}_{{\rm C}}$. These results unify the superconducting phase transitions from the monolayer to the bulk underdoped Bi2212, and can be collectively referred to as the BKT transition with interlayer coupling.
Double-edged sword of technological progress to climate change depends on positioning in global value chains

Abstract
Technological progress (TP) is a double-edged sword to global climate change. This study for the first time reveals rebound and mitigation effects of efficiency-related TP in global value chains (GVCs) on greenhouse gas (GHG) emissions. The integrated effects of TP depend on the positioning of sectors in GVCs. The cost-saving TP in upstream sectors would stimulate downstream demand. This produces stronger rebound effects than mitigation potentials and leads to global GHG emission increments (e.g. TP in the gas sector of China and petroleum and coal products sector of South Korea). In contrast, sectors located in the trailing end of GVCs have greater potentials for GHG emission mitigation through TP, mainly due to the reduction of upstream inputs. (e.g. the construction sector of China and dwelling sector of the United States). Global GHG emissions and production outputs can be either a trade-off or a win–win relationship on account of TP than rebound effects, because TP in different sectors could possibly increase or decrease the emission intensity of GVCs. This study could recognize the most productive spots for GHG emission mitigation through efficiency-related TP. It provides a new perspective for international cooperation to promote global GHG emission mitigation.

Abstract
Caffeine has significant effects on neurovascular activity and behavior throughout the sleep–wake cycle. We used a minimally invasive microchip/video system to continuously record effects of caffeine in the drinking water of freely behaving mice. Chronic caffeine shifted both rest and active phases by up to 2 h relative to the light–dark cycle in a dose-dependent fashion. There was a particular delay in the onset of rapid eye movement (REM) sleep as compared with non-REM sleep during the rest phase. Chronic caffeine increased wakefulness during the active phase and consolidated sleep during the rest phase; overall, there was no net change in the amount of time spent in the wake, sleep, or REM sleep states during caffeine administration. Despite these effects on wakefulness and sleep, chronic caffeine decreased mean cerebral blood volume (CBV) during the active phase and increased mean CBV during the rest phase. Chronic caffeine also increased heart rate variability in both the sleep and wake states. These results provide new insight into the effects of caffeine on the biology of the sleep–wake cycle. Increased blood flow during sleep caused by chronic caffeine may have implications for its potential neuroprotective effects through vascular mechanisms of brain waste clearance.

Abstract
Electronic nicotine delivery systems (ENDS) have been associated with a dramatic increase in youth becoming addicted to nicotine following decades-long decline in cigarette smoking uptake. The United States Food and Drug Administration, Center for Tobacco Products (FDA/CTP) is responsible for regulating devices and consumable materials associated with ENDS. State and federal regulations regarding flavoring compounds in ENDS liquids (e-liquids) may be circumvented when vendors market refillable reservoirs side-by-side with noncompliant e-liquids. This study investigated the effect of third-party refillable versus manufacturer-supplied single-use reservoirs on total particulate matter (TPM) and nicotine emissions. The maximum TPM yield per puff was 5.6 times higher for the third-party (Blankz) reservoir (12.4 mg/puff) in comparison with the manufacturer’s (JUUL) reservoir (2.2 mg/puff), whereas the maximum TPM concentration was over 7 times higher for third party (0.200 mg/ml) versus manufacturer (0.028 mg/ml) pod. The third-party pod was tested with nicotine concentrations ranging from 0% to 4%. The mass ratio of nicotine present in the aerosol (mg Nic/mg TPM) was found to be approximately the same as the mass ratio of the e-liquid (mg Nic/mg e-liquid) for both pods and all 3 nicotine laden e-liquids tested. Toxicant exposure may increase when consumers use third-party pods with ENDS devices. Refillable reservoirs are a significant barrier to regulatory restrictions on potentially toxic additives to e-liquids. It is recommended FDA/CTP require emissions characterization of third-party reservoirs used with each ENDS they are compatible with and should be required to demonstrate no increased potential toxicant exposure in comparison with manufacturer-provided reservoirs.
