Effects of mental context reinstatement on accuracy and recollective experience
Authors: Faber Peter , Nielsen Niels Peter , Berntsen Dorthe 
Published: June 2023

AbstractObtaining eyewitness accounts after an event can aid criminal investigations. Mental Reinstatement of Context (MRC) is used to improve memory. However, direct comparisons have identified little effects of MRC relative to free delivery with No‐MRC, and little is known about the effects of MRC on subjective memory characteristics and the role of individual differences in autobiographical memory. Here we exposed 234 participants to a naturalistic film and randomly assigned them to either MRC or No‐MRC before requesting written memory reports and memory characteristics ratings. They also answered an autobiographical memory test. MRC participants reported more unverifiable, but not more accurate, details in Free Recall, whereas they performed better in Cued Recall and delivered higher ratings of Reliving, Vividness, Re‐experience, and Emotions, suggesting a richer recall experience, while Belief/confidence and Scene ratings did not differ. Individual differences in autobiographical memory correlated with memory characteristics but not with accuracy performances.

ObjectiveThere is an increased risk of fracture in individuals with ankylosing spondylitis (AS) compared to the general population, possibly due to systemic inflammatory effects. The use of tumor necrosis factor inhibitors (TNFi) may reduce fracture risk by inhibiting inflammation. We assessed fracture rates in AS versus non‐AS comparators and whether these rates have changed since the introduction of TNFi.MethodsWe used the national Veterans Affairs database to identify adults ≥18 years old with ≥1 International Classification of Diseases, Ninth Revision (ICD‐9)/ICD‐10 code for AS and at least 1 disease‐modifying antirheumatic drug prescription. As comparators, we selected a random sample of adults without AS diagnosis codes. We calculated fracture incidence rates for AS and comparators, with direct standardization to the cohort structure in 2017. To compare fracture rates from 2000 to 2002 (pre‐TNFi) versus 2004–2020 (TNFi era), we performed an interrupted time series analysis.ResultsWe included 3,794 individuals with AS (mean age 53 years, 92% male) and 1,152,805 comparators (mean age 60 years, 89% male). For AS, the incidence rate of fractures increased from 7.9/1,000 person‐years in 2000 to 21.6/1,000 person‐years in 2020. The rate also increased among comparators, although the ratio of fracture rates (AS/comparators) remained relatively stable. In the interrupted time series, the fracture rate for AS patients in the TNFi era was nonsignificantly increased compared to the pre‐TNFi era.ConclusionFracture rates have increased over time for both AS and non‐AS comparators. The fracture rate in individuals with AS did not decrease after TNFi introduction in 2003.

ObjectiveDisparities in COVID‐19 vaccine and booster uptake persist. This study aimed to obtain perspectives from community and physician stakeholders on COVID‐19 vaccine and booster hesitancy and strategies to promote vaccine uptake among Black individuals with rheumatic and musculoskeletal conditions.MethodsWe invited community leaders and physicians in greater Boston and Chicago to participate in semi‐structured interviews using a moderator guide developed a priori. Participants were queried about how to best address vaccine hesitancy, strategies to target high‐risk populations, and factors to identify future community leaders. Interviews were audio recorded, transcribed verbatim, and analyzed thematically using Dedoose.ResultsA total of 8 physicians and 12 community leaders participated in this study between November 2021 and October 2022. Qualitative analyses revealed misinformation/mixed messaging and mistrust, with subthemes including conspiracy theories, concerns regarding vaccine development and function, racism and historical injustices, and general mistrust of health care systems as the top cited reasons for COVID‐19 vaccine hesitancy. Participants also shared demographic‐specific differences, such as race, ethnicity, age, and gender that influenced the identified themes, with emphasis on COVID‐19 vaccine access and apathy. Strategies for community‐based vaccine‐related information dissemination included personal storytelling with an iterative and empathetic approach, while recognizing the importance of protecting community leader well‐being.ConclusionTo increase vaccine uptake among Black individuals with rheumatic conditions, strategies should acknowledge and respond to racial/ethnic and socioeconomic injustices that engender vaccine hesitancy. Messaging should be compassionate, individually tailored, and recognize heterogeneity in experiences and opinions. Results from these analyses will inform a planned community‐based intervention in Boston and Chicago.image

AbstractStrong spin‐charge interactions in several ferromagnets are expected to lead to subpicosecond (sub‐ps) magnetization of the magnetic materials through control of the carrier characteristics via electrical means, which is essential for ultrafast spin‐based electronic devices. Thus far, ultrafast control of magnetization has been realized by optically pumping a large number of carriers into the d or f orbitals of a ferromagnet; however, it is extremely challenging to implement by electrical gating. This work demonstrates a new method for sub‐ps magnetization manipulation called wavefunction engineering, in which only the spatial distribution (wavefunction) of s (or p) electrons is controlled and no change is required in the total carrier density. Using a ferromagnetic semiconductor (FMS) (In,Fe)As quantum well (QW), instant enhancement, as fast as 600 fs, of the magnetization is observed upon irradiating a femtosecond (fs) laser pulse. Theoretical analysis shows that the instant enhancement of the magnetization is induced when the 2D electron wavefunctions (WFs) in the FMS QW are rapidly moved by a photo‐Dember electric field formed by an asymmetric distribution of the photocarriers. Because this WF engineering method can be equivalently implemented by applying a gate electric field, these results open a new way to realize ultrafast magnetic storage and spin‐based information processing in present electronic systems.

AbstractA deep understanding of the effect of the A‐site cation cross‐exchange on the hot‐carrier relaxation dynamics in perovskite quantum dots (PQDs) has profound implications on the further development of disruptive photovoltaic technologies. In this study, the hot carrier cooling kinetics of pure FAPbI3 (FA+, CH(NH2)2+), MAPbI3 (MA+, CH3NH3++), CsPbI3 (Cs+, Cesium) and alloyed FA0.5MA0.5PbI3, FA0.5Cs0.5PbI3, and MA0.5Cs0.5PbI3 QDs are investigated using ultrafast transient absorption (TA) spectroscopy. The lifetimes of the initial fast cooling stage (<1 ps) of all the organic cation‐containing PQDs are shorter than those of the CsPbI3 QDs, as verified by the electron‐phonon coupling strength extracted from the temperature‐dependent photoluminescence spectra. The lifetimes of the slow cooling stage of the alloyed PQDs are longer under illumination greater than 1 sun, which is ascribed to the introduction of co‐vibrational optical phonon modes in the alloyed PQDs. This facilitated efficient acoustic phonon upconversion and enhanced the hot‐phonon bottleneck effect, as demonstrated by first‐principles calculations.

AbstractMicrovascular endothelial cells (MiVECs) impair angiogenic potential, leading to microvascular rarefaction, which is a characteristic feature of chronic pressure overload‐induced cardiac dysfunction. Semaphorin3A (Sema3A) is a secreted protein upregulated in MiVECs following angiotensin II (Ang II) activation and pressure overload stimuli. However, its role and mechanism in microvascular rarefaction remain elusive. The function and mechanism of action of Sema3A in pressure overload‐induced microvascular rarefaction, is explored, through an Ang II‐induced animal model of pressure overload. RNA sequencing, immunoblotting analysis, enzyme‐linked immunosorbent assay, quantitative reverse transcription polymerase chain reaction (qRT‐PCR), and immunofluorescence staining results indicate that Sema3A is predominantly expressed and significantly upregulated in MiVECs under pressure overload. Immunoelectron microscopy and nano‐flow cytometry analyses indicate small extracellular vesicles (sEVs), with surface‐attached Sema3A, to be a novel tool for efficient release and delivery of Sema3A from the MiVECs to extracellular microenvironment. To investigate pressure overload‐mediated cardiac microvascular rarefaction and cardiac fibrosis in vivo, endothelial‐specific Sema3A knockdown mice are established. Mechanistically, serum response factor (transcription factor) promotes the production of Sema3A; Sema3A‐positive sEVs compete with vascular endothelial growth factor A to bind to neuropilin‐1. Therefore, MiVECs lose their ability to respond to angiogenesis. In conclusion, Sema3A is a key pathogenic mediator that impairs the angiogenic potential of MiVECs, which leads to cardiac microvascular rarefaction in pressure overload‐induced heart disease.

Abstract3D Cu current collectors have been demonstrated to improve the cycling stability of Li metal anodes, however, the role of their interfacial structure for Li deposition pattern has not been investigated thoroughly. Herein, a series of 3D integrated gradient Cu‐based current collectors are fabricated by the electrochemical growth of CuO nanowire arrays on Cu foil (CuO@Cu), where their interfacial structures can be readily controlled by modulating the dispersities of the nanowire arrays. It is found that the interfacial structures constructed by sparse and dense dispersion of CuO nanowire arrays are both disadvantageous for the nucleation and deposition of Li metal, consequently fast dendrite growth. In contrast, a uniform and appropriate dispersity of CuO nanowire arrays enables stable bottom Li nucleation associated with smooth lateral deposition, affording the ideal bottom‐up Li growth pattern. The optimized CuO@Cu‐Li electrodes exhibit a highly reversible Li cycling including a coulombic efficiency of up to ≈99% after 150 cycles and a long‐term lifespan of over 1200 h. When coupling with LiFePO4 cathode, the coin and pouch full‐cells deliver outstanding cycling stability and rate capability. This work provides a new insight to design the gradient Cu current collectors toward high‐performance Li metal anodes.

AbstractAt high current densities, gas bubble escape is the critical factor affecting the mass transport and performance of the electrolyzer. For tight assembly water electrolysis technologies, the gas diffusion layer (GDL) between the catalyst layer (CL) and the flow field plate plays a critical role in gas bubble removal. Herein, we demonstrate that the electrolyzer's mass transport and performance can be significantly improved by simply manipulating the structure of the GDL. Combined with 3D printing technology, ordered nickel GDLs with straight‐through pores and adjustable grid sizes are systematically studied. Using an in situ high‐speed camera, the gas bubble releasing size and resident time have been observed and analyzed upon the change of the GDL architecture. The results show that a suitable grid size of the GDL can significantly accelerate mass transport by reducing the gas bubble size and the bubble resident time. An adhesive force measurement has further revealed the underlying mechanism. We then proposed and fabricated a novel hierarchical GDL, reaching a current density of 2 A/cm2 at a cell voltage of 1.95 V and 80 °C, one of the highest single‐cell performances in pure‐water‐fed anion exchange membrane water electrolysis (AEMWE).

Published: June 2023

AbstractAn understanding of the CO2 adsorption mechanisms on small‐pore zeolites is of practical importance in the development of more efficient adsorbents for the separation of CO2 from N2 or CH4. Here we report that the CO2 isotherms at 25–75 °C on cesium‐exchanged phillipsite zeolite with a Si/Al ratio of 2.5 (Cs‐PHI‐2.5) are characterized by a rectilinear step shape: limited uptake at low CO2 pressure (PCO2) is followed by highly cooperative uptake at a critical pressure, above which adsorption rapidly approaches capacity (2.0 mmol g−1). Structural analysis reveals that this isotherm behavior is attributed to the high concentration and large size of Cs+ ions in dehydrated Cs‐PHI‐2.5. This results in Cs+ cation crowding and subsequent dispersal at a critical loading of CO2, which allows the PHI framework to relax to its wide pore form and enables its pores to fill with CO2 over a very narrow range of PCO2. Such a highly cooperative phenomenon has not been observed for other zeolites.

AbstractTo achieve the Fe−N−C materials with both high activity and durability in proton exchange membrane fuel cells, the attack of free radicals on Fe−N4 sites must be overcome. Herein, we report a strategy to effectively eliminate radicals at the source to mitigate the degradation by anchoring CeO2 nanoparticles as radicals scavengers adjacent (Scaad‐CeO2) to the Fe−N4 sites. Radicals such as ⋅OH and HO2⋅ that form at Fe−N4 sites can be instantaneously eliminated by adjacent CeO2, which shortens the survival time of radicals and the regional space of their damage. As a result, the CeO2 scavengers in Fe−NC/Scaad‐CeO2 achieved ~80 % elimination of the radicals generated at the Fe−N4 sites. A fuel cell prepared with the Fe−NC/Scaad‐CeO2 showed a smaller peak power density decay after 30,000 cycles determined with US DOE PGM‐relevant AST, increasing the decay of Fe−NCPhen from 69 % to 28 % decay.

AbstractHeterogeneous single‐metal‐site catalysts usually suffer from poor stability, thereby limiting industrial applications. Dual Pd1−Ru1 single‐atom‐sites supported on porous ionic polymers (Pd1−Ru1/PIPs) were constructed using a wetness impregnation method. The two isolated metal species in the form of a binuclear complex were immobilized on the cationic framework of PIPs through ionic bonds. Compared to the single Pd‐ or Ru‐site catalyst, the dual single‐atom system exhibits higher activity with 98 % acetylene conversion and near 100 % selectivity to dialkoxycarbonylation products, as well as better cycling stability for ten cycles without obvious decay. Based on DFT calculations, it was found that the single‐Ru site exhibited a strong CO adsorption energy of −1.6 eV, leading to an increase in the local CO concentration of the catalyst. Notably, the Pd1−Ru1/PIPs catalyst had a much lower energy barrier of 2.49 eV compared to 3.87 eV of Pd1/PIPs for the rate‐determining step. The synergetic effect between neighboring single sites Pd1 and Ru1 not only enhanced the overall activity, but also stabilized PdII active sites. The discovery of synergetic effects between single sites can deepen our understanding of single‐site catalysts at the molecular level.
A Review on Flash Sintering of Graphene Oxide Films: Mechanism and Recent Advances in the Field
Authors: Mitra Sangha , Katiyar Monica 
Published: June 2023

AbstractThis review highlights the significance of flash sintering, a photothermal route, in reducing graphene oxide (GO) films. Essentially, extensive efforts are devoted to form graphene electrodes due to its distinctive properties, such as high surface area, excellent electrical conductivity, and optical transparency, owing to which it finds widespread use in energy storage devices, wearable electronics, sensors, and optoelectronics. Thus, rapidly rising market demands for these applications necessitate the need of a technique offering ease of manufacturability and scalability for production of graphene electrodes. The solution‐processed graphene electrodes (SPGEs) are promising to fulfil these requirements. Particularly, SPGEs are fabricated by reducing GO film to graphene/reduced graphene oxide (rGO) by utilizing any reduction method, such as chemical, solvothermal, electrochemical, etc. Lately, flash sintering has garnered substantial attention as a promising reduction route for rapid, clean, and green production of graphene electrodes. This review briefly describes the underlying principle, mechanism, and parameters of flash sintering to develop an insight and advantages of this method over extensively used reduction methods. The review is a systematic summarization of the electrical, optical, and microstructural properties of rGO films/electrodes fabricated using this technique.

AbstractHerein we report a catalyst, metal and additive free generation of carbonyl ylides by blue LED irradiation of aryl diazoacetates in presence of aldehydes. The resulting ylides underwent [3+2] cycloaddition with substituted maleimides present in the reaction mixture to afford 4, 6‐dioxo‐hexahydro‐1H‐furo[3, 4‐c] pyrrole in excellent yields. Fifty compounds were synthesized based on this scaffold. Molecular docking indicated them to be potential poly ADP ribose polymerase (PARP) inhibitor. Screening a representative member of the library against PARP‐1 enzyme revealed a few potential inhibitors with IC50 of 600–700 nM. The phenotypic screening against MCF7, A549 and HepG2 cells furthermore indicated that these compounds selectively inhibit the proliferation of A549, HeLa and HepG2 cells with IC50 of 1–2 μM. The mechanism of action of the most active compound at the cellular level was investigated.

Published: June 2023

AbstractCryptophanes show different conformations in solution and solid state depending upon various factors, such as the length of connecting linkers, medium, and nature of the incoming guest molecule(s). A cyclotriguaiacylenes (CTG) based cryptophane molecule was synthesized using click chemistry containing three triazole linkers and studied as well. This molecule shows two conformations,out‐out crown‐crown(CC), andout‐in CC, in the presence or absence of guest molecule(s), as studied both in solution and solid state. Theout‐in CC, in which both CTG fragments are in crown conformation with one crown sitting above the other, could be obtained by slow escape of the trapped acetone molecules fromout‐out CCin solid state. This transformation could be obtained through a single‐crystal‐to‐single‐crystal (SCSC) transformation from a large volumeout‐out CCto a smaller volumeout‐in CCconformation which is also supported by density functional theory calculations.

Published: June 2023

AbstractDue to the lack of security mechanisms and sensor resources, the IPv6 Routing Protocol for Low power and Lossy networks (RPL) is vulnerable to various attacks, among which Sybil attack has received a lot of attention. This paper proposes a novel scheme based on coarse‐grained localization and fine‐grained isolation (CLFI) for defending Sybil attack. In CLFI, normal neighbor nodes are identified based on received signal strength indicator (RSSI). To further identify Sybil nodes, a physical address identifier called
is defined, which is calculated as the difference of RSSI at two different receivers when they are receiving the same packet. In order to facilitate the calculation of
, a set of anchor nodes are deployed to broadcast the received RPL control packets. Then Sybil behaviors can be detected by comparing the physical address identifier with the logical address embedded in the received packets. The proposed CLFI scheme has been completely implemented in the Contiki operating system. The extensive evaluation in comparison with the state‐of‐the‐art scheme indicates that CLFI can quickly localize and isolate Sybil nodes.
