AbstractFinding new efficient p‐type sensitizers for NiO photocathodes is a great challenge for the development of promising low‐cost tandem dye‐sensitized solar cells (DSSCs). Now, the focus of researchers investigating these cells has been to create high‐performance p‐type systems. With this intention, herein, the design and synthesis of six new phenoxazine‐based donor–acceptor (D–A)‐configured organic dyes PO1–6 was reported, comprising different acceptor moieties specially designed for the sensitization of mesoporous p‐type semiconductor NiO for the construction of p‐type DSSCs (p‐DSSCs). This work includes structural, photophysical, thermal, electrochemical, theoretical, and photoelectrochemical studies of these dyes, including evaluation of their structure‐property relationships. The optical studies revealed that PO1–6 displayed adequate absorption and emission features in the range of 480–550 and 560–650 nm, respectively, with a bandgap in the order of 2.05–2.40 eV, and their thermodynamic parameters favored an efficient interfacial charge transfer involving NiO. Among the six new dyes, the device based on sensitizer PO2 carrying electron‐withdrawing 1,3‐diethyl‐2‐thiobarbituric acid achieved the highest power conversion efficiency of 0.031 % (short‐circuit current density=0.89 mA cm−2, open‐circuit voltage=101 mV, and fill factor=35 %). Conclusively, the study furnishes an understanding of the intricacies involved in the structural modification of phenoxazine‐based sensitizers to further ameliorate the performance of the p‐type DSSCs.

SummaryInternet of Vehicles (IoVs), the emerging trend of Internet of Things (IoTs), has undoubtedly become a promising trend to improve communication among vehicles on the roads. Vehicle‐to‐everything (V2X) communication that is based on 5G technology enables vehicle users to communicate and collaborate with each other to enhance road traffic efficiency and safety. Owing to the increased traffic load and restricted resources of existing network substructure, a channel that responds to the latency and reliability needs of V2X communication must be designed. Thereby, several intelligent spectrum allocation techniques have been proposed to improve the system's overall effectiveness. In this paper, we discuss the spectrum sharing issue of V2X communication in Device‐to‐Device (D2D)‐based cellular networks. We propose a new multi‐layer neural network (MLNN)‐based Resource Allocation and sharing approach (MNNRA) for D2D‐based V2X communications. According to the main advantages of MLNN, the proposed algorithm takes several profits by improving system performance while reducing computational complexity. Numerical analysis is presented to approve the effectiveness of our proposed solution in terms of network sum rate, packet reception ratio, resource utilization ratio, and time complexity.

AbstractBackgroundPancreato‐biliary endoscopic procedures often need to be performed under deep intravenous sedation. The patients are at an increased risk of respiratory depression influenced by the anatomical dead space of the upper respiratory system. We aimed to evaluate the benefit of oxygen delivery through a single‐sided trans‐nasal catheter (TC) for patients undergoing pancreato‐biliary endoscopy.MethodsOxygen supplementation during the procedure was provided either by insertion of a single‐sided TC or insertion of a conventional nasal catheter (NC). A prospective, single‐blind, randomized controlled study was conducted in two groups.ResultsThe number of patients who indicated a decrease in the peripheral transcutaneous oxygen saturation (SpO2; desaturation) was significantly lower in the TC group than in the counterpart (8/58; 13.8% vs. 26/58; 44.8% p < 0.001). The efficient oxygen delivery in the safe range was better conserved in the TC group than in the NC one. There was no adverse effect on both groups. The maximum SpO2 while the endoscopic procedure was significantly higher in the TC group (99.7% vs. 99.3% p = 0.016) and the minimum SpO2 was also significantly higher in the same group (97.7% vs. 94.1% p < 0.0001), which meant that the efficient oxygen delivery was better maintained in TC group than the NC group.ConclusionsA single‐sided TC placed in the pharynx in patients undergoing pancreato‐biliary endoscopy prepares a superior condition of the patients for venous sedation, maintained hyper‐oxygen saturation and a relatively higher SpO2 level to be maintained in limited conditions to reduce the dead space with acceptable tolerance, as compared to the placement of a conventional NC.

AbstractObjectivesCapsule endoscopy (CE) has been shown to have poor diagnostic performance when the capsule passes quickly through the small bowel, especially the proximal jejunum. This study aimed to evaluate the diagnostic yield of proximal jejunal lesions with third‐generation CE technology.MethodsWe retrospectively examined 138 consecutive patients, 76 (55.0%) of whom were men. The patients’ median age was 70 years, and proximal jejunal lesions were detected by CE and/or double‐balloon endoscopy at Hiroshima University Hospital between January 2011 and June 2021. We analyzed the diagnostic accuracy of CE for proximal jejunal lesions and compared the characteristics of the discrepancy between the use of CE and double‐balloon endoscopy with Pillcam SB 2 (SB2) and Pillcam SB 3 (SB3).ResultsSB2 and SB3 were used in 48 (35%) and 90 (65%) patients, respectively. There was no difference in baseline characteristics between these groups. Small‐bowel lesions in the proximal jejunum comprised 75 tumors (54%), 50 vascular lesions (36%), and 13 inflammatory lesions (9%). The diagnostic rate was significantly higher in the SB3 group than in the SB2 group for tumors (91% vs. 72%, p < 0.05) and vascular lesions (97% vs. 69%, p < 0.01). For vascular lesions, in particular, the diagnostic rate of angioectasia improved in the SB3 group (100%) compared with that in the SB2 group (69%).ConclusionsSB3 use improved the detection of proximal jejunal tumors and vascular lesions compared with SB2 use.

AbstractThe expansion of anthropogenic noise poses an emerging threat to the survival and reproductive success of various organisms. Previous investigations have focused on the detrimental effects of anthropogenic noise on the foraging behavior in some terrestrial and aquatic animals. Nevertheless, the role of airport noise in impairing foraging activities of most wild animals has been neglected. Here, we aimed to assess whether foraging behavior in free‐living Japanese pipistrelle bats (Pipistrellus abramus) can be disturbed by airport noise. We used audio recording to monitor foraging activities of bats at 11 sites around the runway of a municipal airport. We quantified noise level and spectra, aircraft activity, habitat type, nightly temperature, wind speed, and moon phase for each site. The analysis revealed that noise level and aircraft activity were significant negative predictors for the number of bat passes and feeding buzzes around the runway, even after controlling for the effects of other environmental factors. There was no marked spectral overlap between bat echolocation pulses and airport noise in the presence and absence of low‐flying aircraft. The spectro‐temporal parameters of echolocation vocalizations emitted by bats were dependent on noise level, aircraft activity, and habitat type. These results provide correlative evidence that airport noise can reduce foraging activities of wild pipistrelle bats. Our findings add to the current knowledge of adverse impacts of airport noise on foraging bats in artificial ecosystems and provide a basis for further research on the mechanisms behind noise pollution near airports.

Published: June 2022

SummaryCO2 geological storage (CGS) is one of the important means to effectively reduce greenhouse gas emissions. Mineral trapping is an important factor affecting long‐term storage security. The process of mineral trapping is significantly affected by mineral reaction kinetics. Therefore, it is of great significance to clarify the influence trend and degree of the control equation of mineral reaction kinetics on predicting the process of CO2 storage and the amount of mineral sequestration. In this paper, the effect of different reaction rate equations on predicting long‐term CO2 sequestration mechanisms are compared and analyzed by numerical simulation using the existing reaction rate equations. The results show that different reaction rate equations of related minerals have no significant effect on predicting the total amount of CO2 sequestration and the transformation relationship among different minerals, but will significantly affect different forms of CO2 sequestration, especially mineral trapping. The ratio of mineral trapping predicted by different reaction rate equations is 20% to 41%. And the predicted CO2 mineral trapping rate is twice as high when the linear rate equation is used as when the nonlinear rate equation is used. In previous studies, linear rate equations have been widely used to describe the dissolution/precipitation reactions of related minerals, which may greatly overestimate the reaction rate and theoretical capture capacity of minerals. Therefore, it is urgent to carry out reaction kinetics experiments and numerical simulation studies on various major minerals under the condition of CO2 geological storage in the future, to obtain a more accurate mineral dissolution/precipitation reaction rate equation and improve the ability to evaluate the long‐term CO2 geological sequestration safety.

Abstract
Polycyclic aromatic hydrocarbons (PAHs) are structurally diverse organic chemicals that can have adverse effects on the health of fishes through activation of aryl hydrocarbon receptor 2 (AhR2). They are ubiquitous in the environment, but alkyl PAHs are more abundant in some environmental matrices. However, relatively little is known regarding the effects of alkylation on the toxicity of PAHs to fishes in vivo and how this relates to potency for activation of AhR2 in vitro. Therefore, the objectives of the present study were to determine the toxicity of benz[a]anthracene and three alkylated homologs representing various alkylation positions to early life stages of zebrafish (Danio rerio) and to assess the potency of each for activation of the zebrafish AhR2 in a standardized in vitro AhR transactivation assay. Exposure of embryos to each of the PAHs caused a dose-dependent increase in mortality and malformations characteristic of AhR2 activation. Each alkyl homolog had in vivo toxicities and in vitro AhR2 activation potencies different from those of the parent PAH in a position-dependent manner. However, there was no statistically significant linear relationship between responses measured in these assays. The results suggest a need for further investigation into the effect of alkylation on the toxicity of PAHs to fishes and greater consideration of the contribution of alkylated homologs in ecological risk assessments.

AbstractPhotothermal therapy (PTT), as an important noninvasive and effective tumor treatment method, has been extensively developed into a powerful cancer therapeutic technique. Nevertheless, the low photothermal conversion efficiency and the limited tissue penetration of typical photothermal therapeutic agents in the first near‐infrared (NIR‐I) region (700–950 nm) are still the major barriers for further clinical application. Here, we proposed an organic/inorganic dual‐PTT agent of synergistic property driven by polydopamine‐modified black‐titanium dioxide (b‐TiO2@PDA) with excellent photoconversion efficiency in the second NIR (NIR‐II) region (1000–1500 nm). More specifically, the b‐TiO2 treated with sodium borohydride produced excessive oxygen vacancies resulting in oxygen vacancy band that narrowed the b‐TiO2 band gap, and the small band gap led to NIR‐II region wavelength (1064 nm) absorbance. Furthermore, the combination of defect energy level trapping carrier recombination heat generation and conjugate heat generation mechanism, significantly improved the photothermal performance of the PTT agent based on b‐TiO2. The photothermal properties characterization indicated that the proposed dual‐PTT agent possesses excellent photothermal performance and ultra‐high photoconversion efficiency of 64.9% under 1064 nm laser irradiation, which can completely kill esophageal squamous cells. Meanwhile, Gd2O3 nanoparticles, an excellent magnetic resonance imaging (MRI) agent, were introduced into the nanosystem with similar dotted core–shell structure to enable the nanosystem achieve real‐time MRI‐monitored cancer therapeutic performance. We believe that this integrated nanotherapeutic system can not only solve the application of PTT in the NIR‐II region, but also provide certain theoretical guidance for the clinical diagnosis and treatment of esophageal cancer.
Exploring the dynamics of the equity–commodity nexus: A study of base metal futures
Authors: Saishree Ipsita , Padhi Puja 
Published: June 2022

AbstractThis empirical exercise explores different aspects of the time‐varying linkage between the commodity and equity markets in India, focusing on base metal futures. The Dynamic Conditional Correlation model (2002) and Diebold–Yilmaz spillover index (2012) are employed to ascertain the presence, pattern, direction, and magnitude of the connectedness between the returns of base metal futures and related equity indices over the period of 2006–2019. The study builds on a less‐studied “input” channel of linkage between the two, reckoning with the economic fundamentals of demand–supply interaction. Our results show that 36% of the return forecast error variance originates from spillovers, to which the contribution of equity indices is minimal. It indicates segmentation between the two markets which offer the scope for potential diversification. Further, base metal futures are the net transmitters and equity indices are the net recipients of spillovers. Positive correlations outweigh the negative correlations, in both frequency and magnitude.

Published: June 2022

AbstractMillions of sub‐daily sea‐level pressure observations taken between 1919 and 1960 over the British and Irish Isles were transcribed from paper records in the early 2000s but were not published and subsequently forgotten. A chance discussion led to the rediscovery of the transcribed data and 5.47 million observations from 160 locations are now made available, although the data have not been fully quality‐controlled. Much of the data are 3‐hourly, allowing for detailed examinations of synoptic weather variations for this region and time period, and will be invaluable for constraining future reanalyses. We illustrate the value of the data using a stormy period during October and November 1928 and discuss the remaining quality‐control issues.

AbstractObjectivesThe population of older adults is growing fast, especially in Europe and Northern America. Old age is often associated with mental health comorbidities. Moreover, life expectancy of people suffering from psychiatric disorders has increased, but with age‐related difficulties, such as loss of independence. This represents a challenge for public health policies, as this population requires specific care and living conditions. As a response, a convention was signed between living facilities for dependent elderly (EHPAD) and the GHU Paris Psychiatry and Neurosciences. The agreement included dedicated places in EHPAD for older patients with psychiatric disorders. The aim of the study was to describe the sociodemographic and clinical characteristics of those patients.MethodsWe conducted a cross‐sectional study among patients who applied for an EHPAD admission.ResultsBetween 2016 and 2019, 163 patients applied for placement in an EHPAD, and 117 were admitted (72%). Applicants were 71 years old on average. Admitted patients were older than non‐admitted and lived in different Parisian sectors. Among admitted patients, nine in 10 were single, divorced or widowed, and 64.3% were childless. Almost half of them were schizophrenic or had delusional disorders (46.9%), and 65.3% were considered as moderately dependent. At the time of the study, 89 patients still lived in EHPAD. Almost half of them had anxiety and depressive disorders (48.3%), 19.1% had cognitive disorders, and 42.7% manifested agitation.ConclusionsOur study highlighted older psychiatric patients' specificities regarding their admission status into long‐term living facilities.

Published: June 2022

AbstractVisuospatial attention is strongly lateralized, with the right hemisphere commonly exhibiting stronger activation and connectivity patterns than the left hemisphere during attentive processes. However, whether such asymmetry influences inter‐hemispheric information transfer and behavioral performance is not known. Here we used a region of interest (ROI) and network‐based approach to determine steady‐state fMRI functional connectivity (FC) in the whole cerebral cortex during a leftward/rightward covert visuospatial attention task. We found that the global FC topology between either ROIs or networks was independent on the attended side. The side of attention significantly modulated FC strength between brain networks, with leftward attention primarily involving the connections of the right visual network with dorsal and ventral attention networks in both the left and right hemisphere. High hemispheric functional segregation significantly correlated with faster target detection response times (i.e., better performance). Our findings suggest that the dominance of the right hemisphere in visuospatial attention is associated with an hemispheric functional segregation that is beneficial for behavioral performance.

AbstractObjectiveThe aim of this study was to examine the diagnostic value of ophthalmic artery Doppler indices in predicting preeclampsia along with other markers in the third trimester of pregnancy.MethodsNormotensive pregnancies were included during 28–32 weeks of gestation to undergo uterine and ophthalmic artery Doppler ultrasound. Maternal and fetal characteristics were documented at the visit between the 28 and 32 weeks of gestation, and pregnancy‐associated plasma protein A (PAPP‐A) values in the first trimester were collected to be integrated into a multiparametric prediction model.ResultsOf 795 included participants, 48 cases progressed to preeclampsia. All assessed ophthalmic Doppler parameters including first and second peak systolic velocities (PSVs), second to first peak ratio (PR), and pulsatility index (PI), were statistically different in patients who developed preeclampsia later on. The average PR (sensitivity: 100% [95% CI, 0.81–1.00]; specificity: 90% [95% CI, 0.86–0.93]) and PI between the eyes, PAPP‐A multiple of median and uterine artery PI were determined to be the most important predictors of PE, which were subsequently integrated into a multiple regression model (sensitivity: 94% [95% CI, 0.70–1.00]; specificity: 93% [95% CI, 0.89–0.96]).ConclusionThis study provided a screening method for individuals at higher risk of progressing to preeclampsia in the third trimester of pregnancy.
