Carbon assets and Bitcoin: Hedging roles in global stock markets during the tranquil and turbulent periods?
Authors: Jiang Wei , Zhang Yanyu 
Published: May 2023

AbstractThis paper studies time‐frequency connectedness among carbon assets, Bitcoin, and global stock markets by using the Diebold and Yilmaz method and the Baruník and Křehlík method, to investigate the hedging ability of carbon assets and Bitcoin in global stock markets. Our study finds that both carbon assets and Bitcoin play hedging roles in global stock markets. However, their strength of hedging is negatively correlated with the degree of economic uncertainty and tends to change in different frequency domains. We also show that carbon assets and Bitcoin can act as each other's hedging assets in a great majority of cases. Our results provide useful knowledge for investors to reduce risks and for regulators to regulate carbon assets and cryptocurrency speculation.

AbstractIntroductionManual vacuum aspiration (MVA) is a safe and effective alternative option for the management of first‐trimester miscarriage, termination of pregnancy, or retained pregnancy tissue. Ireland's first MVA clinic was set up in the Rotunda Hospital in April 2020.ObjectiveTo identify the number of women who have undergone MVA since establishing our service, to assess the efficacy and safety of MVA in that service, and to develop local Irish studies that further support the safety of MVA, adding to the international body of evidence.MethodsWith the approval and assistance of the Clinical Audit Committee, we obtained a log of all patients who underwent MVA in the first 18 months of the service. We performed a retrospective electronic chart review using Maternal and Newborn Clinical Management System. We collected the data and preformed a descriptive analysis.ResultsIn total, 86 women underwent MVA, 85 (98.8%) of which were successfully completed. There were no immediate procedural complications, inter‐hospital transfers, or emergency electric vacuum aspiration (EVA) required. We obtained an incomplete evacuation rate of 4.7% (n = 4).ConclusionWe have demonstrated that the MVA service in the Rotunda Hospital is a safe, effective management option with advantages for both the patient and the healthcare system. We recommend consideration for provision of funding and resources to enable expansion of this service nationally in order to give women greater autonomy of choice in the management of early pregnancy complications and termination of pregnancy.

AbstractGranular hydrogels are a promising biomaterial for a wide range of biomedical applications, including tissue regeneration, drug/cell delivery, and 3D printing. These granular hydrogels are created by assembling microgels through the jamming process. However, current methods for interconnecting the microgels often limit their use due to the reliance on postprocessing for crosslinking through photoinitiated reactions or enzymatic catalysis. To address this limitation, we incorporated a thiol‐functionalized thermo‐responsive polymer into oxidized hyaluronic acid microgel assemblies. The rapid exchange rate of thiol‐aldehyde dynamic covalent bonds allows the microgel assembly to be shear‐thinning and self‐healing, with the phase transition behavior of the thermo‐responsive polymer serving as secondary crosslinking to stabilize the granular hydrogels network at body temperature. This two‐stage crosslinking system provides excellent injectability and shape stability, while maintaining mechanical integrity. In addition, the aldehyde groups of the microgels act as covalent binding sites for sustained drug release. These granular hydrogels can be used as scaffolds for cell delivery and encapsulation, and can be 3D printed without the need for post‐printing processing to maintain mechanical stability. Overall, our work introduces thermo‐responsive granular hydrogels with promising potential for various biomedical applications.

AbstractObjectivesCommunities of color in the United States systematically experience inequities in physical and mental health care compared to individuals who identify as non‐Hispanic White. The coronavirus disease 2019 (COVID‐19) pandemic exacerbated these structural drivers of inequity to disproportionate and devastating effects for persons of color. In addition to managing the direct effects of COVID‐19 risk, persons of color were also navigating increased racial prejudice and discrimination. For mental health professionals and trainees of color, the effects of COVID‐19 racial health disparities and the increase in acts of racism may have been compounded by their work responsibilities. The current study used an embedded mixed‐methods approach to examine the differential impact of COVID‐19 on health service psychology (HSP) students of color as compared to their non‐Hispanic White peers.MethodUsing quantitative and qualitative data from the Epidemic‐Pandemic Impacts Inventory, measures of perceived support and of discrimination, and open‐ended questions about students' experiences with racism and microaggressions, we examined the extent to which different racial/ethnic HSP student groups experienced COVID‐19‐related discrimination, the impacts of COVID‐19 felt by students of color, and how these experiences differed from those of their non‐Hispanic White peers.ResultsHSP students of color endorsed greater impacts of the pandemic on both self and others in the home, perceived themselves as less supported by others, and reported more experiences of racial discrimination than non‐Hispanic White HSP students.ConclusionThroughout the graduate experience, HSP students of color and their experiences of discrimination need to be addressed. We provided recommendations to HSP training program directors and students both during and after the COVID‐19 pandemic.

AbstractHerein, the photocatalytic generation of an important solar fuel—H2O2—by a thiophene‐coupled anthraquinone (AQ) and benzotriazole‐based donor (D)–acceptor (A) polymer (PAQBTz) nanoparticles is systematically reported. The visible‐light active and redox‐active D–A type polymer is synthesized employing the Stille coupling polycondensation, and the nanoparticles are obtained by dispersing the PAQBTz polymer and polyvinylpyrrolidone solution, prepared in tetrahydrofuran to water. The polymer nanoparticles (PNPs) produce 1.61 and 1.36 mM mg−1 hydrogen peroxide (H2O2) in the acidic and neutral media, respectively, under AM1.5G simulated sunlight irradiation (λ > 420 nm) with ≈2% modified Solar to Chemical Conversion (SCC) efficiency after 1 h of visible light illumination in acidic condition. The results of the various experiments lay bare the different aspects governing H2O2 production and indicate the H2O2 synthesis through the superoxide anion‐mediated and anthraquinone‐mediated routes.

A linear adaptive second‐order backward differentiation formulation scheme for the phase field crystal equation
Authors: Hou Dianming , Qiao Zhonghua 
Published: May 2023

AbstractIn this article, we present and analyze a linear fully discrete second order scheme with variable time steps for the phase field crystal equation. More precisely, we construct a linear adaptive time stepping scheme based on the second order backward differentiation formulation (BDF2) and use the Fourier spectral method for the spatial discretization. The scalar auxiliary variable approach is employed to deal with the nonlinear term, in which we only adopt a first order method to approximate the auxiliary variable. This treatment is extremely important in the derivation of the unconditional energy stability of the proposed adaptive BDF2 scheme. However, we find for the first time that this strategy will not affect the second order accuracy of the unknown phase function by setting the positive constant large enough such that
The energy stability of the adaptive BDF2 scheme is established with a mild constraint on the adjacent time step radio . Furthermore, a rigorous error estimate of the second order accuracy of is derived for the proposed scheme on the nonuniform mesh by using the uniform bound of the numerical solutions. Finally, some numerical experiments are carried out to validate the theoretical results and the efficiency of the proposed scheme combined with the time adaptive strategy.

AbstractBackgroundDiagnostic mIBG (meta‐iodobenzylguanidine) scans are an integral component of response assessment in children with high‐risk neuroblastoma. The role of end‐of‐induction (EOI) Curie scores (CS) was previously described in patients undergoing a single course of high‐dose chemotherapy (HDC) and autologous hematopoietic cell transplant (AHCT) as consolidation therapy.ObjectiveWe now examine the prognostic significance of CS in patients randomized to tandem HDC and AHCT on the Children's Oncology Group (COG) trial ANBL0532.Study designA retrospective analysis of mIBG scans obtained from patients enrolled in COG ANBL0532 was performed. Evaluable patients had mIBG‐avid, International Neuroblastoma Staging System (INSS) stage 4 disease, did not progress during induction therapy, consented to consolidation randomization, and received either single or tandem HDC (n = 80). Optimal CS cut points maximized the outcome difference (≤CS vs. >CS cut‐off) according to the Youden index.ResultsFor recipients of tandem HDC, the optimal cut point at diagnosis was CS = 12, with superior event‐free survival (EFS) from study enrollment for patients with CS ≤ 12 (3‐year EFS 74.2% ± 7.9%) versus CS > 12 (59.2% ± 7.1%) (p = .002). At EOI, the optimal cut point was CS = 0, with superior EOI EFS for patients with CS = 0 (72.9% ± 6.4%) versus CS > 0 (46.5% ± 9.1%) (p = .002).ConclusionIn the setting of tandem transplantation for children with high‐risk neuroblastoma, CS at diagnosis and EOI may identify a more favorable patient group. Patients treated with tandem HDC who exhibited a CS ≤ 12 at diagnosis or CS = 0 at EOI had superior EFS compared to those with CS above these cut points.
Research on improved gas‐assisted extrusion of plastic sheets based on time–temperature equivalence principle

Published: May 2023

AbstractBased on the time–temperature equivalence principle, the relationship between the melt relaxation time (MRT) and melt heating temperature (MHT) in an improved gas‐assisted extrusion (GAE) of a polypropylene (PP) sheet was investigated by numerical simulations. In the simulations, the MRT was varied and the inherent properties of the MHT were controlled using experimental methods. With an increase in MRT, the velocity in all directions, pressure drop, and shear rate of the melt increased; however, increasing the MRT does not always yield a positive effect on the GAE process of the melt. For instance, the melt velocity increased vertically at the die exit with MRT, resulting in an outward extrudate swell. In addition, the extruded product was intact when the melt was heated to 220°C, which verified the principle of time–temperature equivalence.

Published: May 2023

AbstractObjectiveApproaches to improve earlier diagnosis of cancer often focus on symptom awareness as a key driver of help‐seeking behaviour and other psychological influences are less well understood. This is the first study to explore the role of patient enablement on help‐seeking for people experiencing potential blood cancer symptoms.MethodsA cross‐sectional, nationally representative survey was completed by 434 respondents (>18 years). Questions asked about symptom experiences, medical help‐seeking and re‐consultation. Existing patient enablement items were included in the newly developed Blood Cancer Awareness Measure. We collected data on patient socio‐demographic characteristics.ResultsOf those responding to the survey 224/434 (51.6%) reported experiencing at least one potential blood cancer symptom. Half of those experiencing symptoms (112/224) had sought medical help. Results from logistic regression analysis showed that higher scores on patient enablement were associated with being less likely to seek help (Odds Ratio [OR] 0.89, Confidence Interval [CI] 0.81–0.98) after controlling for socio‐demographics. Separate analyses showed that higher enablement was associated with being more comfortable to re‐consult if symptoms didn't go away or got worse (OR 1.31, CI 1.16–1.48); after a test result suggested there was nothing to worry about, but symptoms persisted (OR 1.23, CI 1.12–1.34) or to request further tests, scans or investigations (OR 1.31, CI 1.19–1.44).ConclusionsContrary to our hypotheses, patient enablement was associated with lower likelihood of help‐seeking for potential blood cancer symptoms. Yet enablement appears to play an important role in likelihood of re‐consulting when symptoms persist, get worse or need further investigation.

Published: May 2023

AbstractThis article is aim to investigate the functional role and potential regulatory mechanisms of solute carrier family 35 member D3 (SLC35D3) in colorectal cancer. Beyond analyzing databases, western blot was used to detect and verify the expression of SLC35D3. Cell proliferation and invasion or migration ability were detected by CCK‐8, EdU, and Transwell assays. Animal experiments were conducted to verify if the biological function of SLC35D3 in vivo is consistent with that in vitro. Beyond SLC family pathway enrichment analysis, the relationship between SLC35D3 and metabolic pathway AMPK was explored using co‐immunoprecipitation and western blot. SLC35D3 is highly expressed in colorectal cancer (CRC) tissue. The overexpression or down regulation of SLC35D3 has been shown to promote or inhibit the biological functions of colorectal cancer, and similar experimental results can be verified in vivo experiments. Based on the high correlation between the SLC family and metabolic pathways, we chose the metabolic‐related AMPK pathway as the subject of our research. Co‐immunoprecipitation and protein analysis demonstrated that SLC35D3 may bind to AMPK molecules and regulate the AMPK pathway of colorectal cancer cells. Based on the above facts, SLC35D3 promotes colorectal cancer progression through regulating AMPK signaling pathway.

Published: May 2023

AbstractIntroductionTo evaluate the current evidence estimating the association between antidepressant use during pregnancy and stillbirth.Search StrategyMEDLINE, EMBASE, and PsychINFO for studies investigating antidepressant use during pregnancy and risk of stillbirth, from inception until 21 January 2022.Selection CriteriaStudies including pregnant women exposed to antidepressants during pregnancy investigating stillbirth were eligible, compared with either unexposed, indicated pregnant women or unexposed women in the general obstetric population.Data Collection and AnalysisData extraction and quality assessment were performed by two authors independently. Meta‐analysis was used to generate pooled‐effect estimates, and the ROBINS‐I tool was used to assess risk of bias for individual studies.Main ResultsSeventeen studies were eligible. Although estimates from meta‐analysis models suggest a small increased risk of stillbirth, summary effect estimate 1.19 (95% confidence interval [CI] 1.06, 1.34) between those individuals taking antidepressants during pregnancy and all other pregnant women, confounding control is likely inadequate. The risk of bias assessment showed most studies were low quality, with no studies scoring low risk; in a meta‐analysis of studies with moderate risk of bias (n = 2), no association was noted, summary effect estimate 1.17 (95% CI 0.97, 1.41). Only six studies adjusted for confounding by indication, the findings of which were summarised narratively.ConclusionsAlthough the overall meta‐analysis found a small association between antidepressant use during pregnancy and stillbirth, this result was likely due to the overall low quality of studies included and by confounding in the underlying studies. Future studies must adequately address potential confounding by indication.

Published: May 2023

AbstractThis article studies data‐driven control of unknown sampled‐data linear systems with communication delays under an event‐triggering transmission mechanism. While event‐triggered control has received much attention in the existing literature, its design and implementation typically require detailed model knowledge. Due to the difficulties in finding accurate models and the abundance of data in many practical applications, we propose a novel data‐driven event‐triggered control scheme for unknown, delayed systems with theoretical guarantees. To this end, as a first step, a model‐based stability condition for the resulting event‐triggered time‐delay system is established using a novel looped‐functional approach. Combining this model‐based condition with the data‐driven representation of linear systems, a data‐based stability condition is derived. Further, methods for co‐designing the controller gain and the event‐triggering matrix are subsequently provided without using any prior knowledge of the system matrices. Finally, numerical examples are presented to corroborate the merits of the proposed data‐driven event‐triggered control schemes relative to existing results.

AbstractLithium‐ion and sodium‐ion batteries (LIBs and SIBs) are crucial in our shift toward sustainable technologies. In this work, the potential of layered boride materials (MoAlB and Mo2AlB2) as novel, high‐performance electrode materials for LIBs and SIBs, is explored. It is discovered that Mo2AlB2 shows a higher specific capacity than MoAlB when used as an electrode material for LIBs, with a specific capacity of 593 mAh g−1 achieved after 500 cycles at 200 mA g−1. It is also found that surface redox reactions are responsible for Li storage in Mo2AlB2, instead of intercalation or conversion. Moreover, the sodium hydroxide treatment of MoAlB leads to a porous morphology and higher specific capacities exceeding that of pristine MoAlB. When tested in SIBs, Mo2AlB2 exhibits a specific capacity of 150 mAh g−1 at 20 mA g−1. These findings suggest that layered borides have potential as electrode materials for both LIBs and SIBs, and highlight the importance of surface redox reactions in Li storage mechanisms.

Published: May 2023

AbstractThe optoelectronic properties of a fully processed red emitting AlGaInP micro‐diode device is measured using standard I‐V and luminescence measurements. A thin specimen is then prepared for in situ transmission electron microscopy analysis by focused ion beam milling, then the changes of electrostatic potential as a function of applied forward bias voltage are mapped by off‐axis electron holography. We demonstrate that the quantum wells in the diode sit on a potential gradient until the threshold forward bias voltage for light emission is reached; at which point the quantum wells are aligned at the same potential. From simulations, a similar effect for the band structure can be demonstrated, where the quantum wells are aligned at the same energy level, and contain electrons and holes that are available for radiative recombination at this threshold voltage. We demonstrate that off‐axis electron holography can be used to directly measure the potential distribution in optoelectronic devices, and is a powerful tool to help better understand their performance and to improve simulations.
