The site itself contains remains from the Old Kingdom onward; the town probably served as the administrative center of the area.
What is the source of preschool children's memories of events from their own lives?

Published: January 2022

AbstractIn experimental tasks, preschool children sometimes mistakenly attribute memories to themselves rather than external sources, with decreasing source errors between 4‐ and 5‐years of age. In this research, we tested whether these developmental changes are also observed in spontaneously generated memories of personal life events. 4‐ and 5‐year olds generated life event memories and provided age estimates for when they took place. The children at both ages most often mentioned events that they could plausibly remember and some memories from external sources, including vicarious memories and events beyond their lifespan. Parents affirmed the accuracy of their children's memories and reported that some events were only told to or were imagined by the children. Our findings suggest that preschool children most often report events that they themselves remember and occasionally include events likely originating from external sources. These results add to the evidence showing that children's memories for events can be accurate.

AbstractTuberculosis (TB), including extrapulmonary TB, is responsible for more than one million deaths in a year worldwide. Existing methods of mycobacteria detection have poor sensitivity, selectivity, and specificity, especially in human tissues. Herein, the synthesis of a cholic acid‐derived fluorescent probe (P4) that can specifically stain the mycobacterium species is presented. It is shown that P4 probe specifically binds with mycobacterial lipids, trehalose monomycolate, and phosphatidylinositol mannoside 6. P4 probe can detect mycobacteria in polymicrobial planktonic cultures and biofilms with high specificity, selectivity, and sensitivity. Moreover, it can detect a single mycobacterium in the presence of 10 000 other bacilli. Unlike the probes that depend on active mycobacterial enzymes, the membrane‐specific P4 probe can detect mycobacteria even in formalin‐fixed paraffin‐embedded mice and human tissue sections. Therefore, the ability of the P4 probe to detect mycobacteria in different biological milieu makes it a potential candidate for diagnostic and prognostic applications in clinical settings.

AbstractThe insolubility of single‐walled carbon nanotubes (SWCNTs) in most common organic solvents has been the cause of a bottleneck in their practical utilization. Aqueous SWCNT inks containing amphiphilic surfactants are widely used for processing including coatings and composite fabrication. Most practical processes are, however, designed to be compatible with organic solvents, generating a technological mismatch between production and utilization. This work reports on the surfactant‐assisted dispersion of SWCNTs in useful organic solvents, at up to quantitative yields. A feature extraction based on machine learning offers seemingly important, highly intuitive physicochemical factors that lead to efficient dispersion. These elucidated factors are associated not only with solvents–surfactant, but also solvent–SWCNT interactions. The organic SWCNT dispersion as well as its research methodology developed here may find widespread applications ranging from nanofluidics to functional materials design.

AbstractRenewable energy storage systems based on oxygen reduction reaction (ORR) call for high‐performance, durable, and low‐cost electrocatalysts. However, practical applications of ORR catalysts available today are hampered by the inability to load accessible catalytic sites efficiently. Herein, a novel and efficient ORR electrocatalyst (Fe2O3/FeNx@CNF) with atomic FeNx sites and neighboring Fe2O3 nanoparticles embedded in interconnected carbon nanofibers prepared via electrospinning is reported. Detailed material characterizations confirm that the as‐prepared catalysts possess a well‐defined fibrous structure with hierarchical pores, large specific surface area, and uniformly distributed Fe2O3/FeNx active sites. Further, it exhibits excellent ORR performance with high onset potential, half‐wave potential, and current density in both alkaline and acidic media. And these electrocatalysts show excellent long‐term performance and tolerance to methanol, exceeding the properties of commercial platinum catalysts. Additionally, the Fe2O3/FeNx@CNF electrocatalyst prepared in this study exhibits high discharge voltage, excellent power density, and cycling durability in Zn–air batteries. Notably, the detailed analyses demonstrate the co‐existence of Fe2O3 nanoparticles and FeNx active sites boost the ORR catalytic activity of the hybrid catalyst. These new findings, particularly the enhancement of intrinsic activity of FeNx sites brought about by Fe2O3 nanoparticles, provide insights into the rational design of hybrid single‐atom ORR electrocatalysts.

AbstractElectronic skins, as a revolution in artificial intelligence, have drawn intensive attention in smart prosthetic devices, wearable health monitors and intelligent robot manufacturing. Conductive hydrogels as building blocks have been highlighted in artificial skin research. Nevertheless, the main challenges of hydrogel‐based electronics are poor temperature tolerance, weak mechanical robustness and limited stretchability. Herein, an organohydrogel is fabricated with “soft and hard” synergistic networks by combining “soft” polyacrylamide (PAM) and catechol‐modified hyaluronic acid (HA‐CA) polymer network with “hard” Laponite nanoparticles. The obtained organohydrogels exhibit excellent environment‐adaptability, super stretchability (>8000%), superior adhesion to various substrates, superfast self‐healing efficiency (<10 s), excellent conductivity (63 mS m−1) even at −0 °C and good biocompatibility. These outstanding properties render the organohydrogels as epidermal flexible sensors. The fabricated sensor exhibits wide strain sensing range (0−300%), super sensitivity (gauge factor, GF = 8.38−133.94) which can effectively detect and discriminate various human activities, and maintain their functions at extremely cold conditions. This versatile organohydrogel offers a platform for practical application of flexible wearable devices in extreme environments.

AbstractDeveloping a simple technique for in situ monitoring of sweating rate can provide real time feedback of individual's dehydration status and further assist in human health management. This work demonstrates the visible darkening of laser‐induced graphene (LIG) after wetting and its wearable practicability in monitoring sweating rate. LIGs with various porous morphologies are generated and their color differences are quantitatively assessed with hue‐saturation‐value model, correlated with the sheet resistance and the porous architecture. Embedding LIG pattern within microchannel enables the direct readout of water‐filled region and arranging length scale marks along microchannel allows direct readout of fluid volume with human eye for more simple measurements. Flexible design of length scale resolution can balance the detection frequency (i.e., real time ability) and its accuracy. The in situ and real time flow rate monitoring performance is successfully adopted on‐body for sweating rate analysis with reasonable accuracy. Apart from the simplicity and low cost, compared to other flow rate sensing methods, the proposed platform is reusable with no special cleaning needed for the microchannel but just drying, and no visible decline of the performance occurs. LIG's darkening strategy endows an avenue for the development of powerful in situ and real time sweating analytical platform.

AbstractSurface plasmon polaritons (SPPs) have great applications in imaging, sensing, waveguide, and communication. Especially in the trending of electromagnetic (EM) metastructure field, researchers used the phase gradient design to achieve the efficient surface wave propagating performance ranging from GHz to THz. However, due to the intrinsic coupling interference from the current structure design, the phase and amplitude of different polarization are hard to freely manipulate simultaneously, making the design of multifunctional channels SPPs still a challenging project. Here, an anisotropic structure is proposed to realize independent control of both polarization and amplitude along different component of the wavefront. By analyzing the polarization dependent mechanism, the hexagon and half‐hexagon meta‐atom are introduced to the coupler structure to tailor the desired phase gradient along different directions under different polarized EM waves. Then the dispersion of coupler is further coupled with the propagating patch metasurface by optimization algorithm. As a result, the multifunctional SPP is achieved, and the multimode excitation can be generated under both linear and circular polarized incidence. Both simulation and experiment validate the effectiveness and wideband of spoof SPPs excitation performance, verifying that this method reduces the excitation condition of surface wave and improves the multiplexing effect of propagation channel.

AbstractPhosphor‐converted light‐emitting diode (pc‐LED) has drawn much interest due to the efficient light in solid‐state lighting, backlight display, security, and electronic devices. Thermal quenching (TQ) induced by nonradiative relaxation is one of the vital challenges that limits the widespread use of phosphors. Much efforts are devoted to designing different approaches to solve the emission loss at increasing temperature. Here, the mechanism of TQ and recent advances of anti‐TQ‐phosphor‐involved 5d–4f, 4f–4f, 6p–6s, 3d–3d transitions are discussed. Several important design strategies for anti‐TQ phosphors are summarized as follows: 1) defect engineering; 2) energy transfer; 3) structural modulation; 4) enhancing crystallinity; 5) layer structural design; 6) negative/zero thermal expansion; 7) surface coating and glass technology. Additionally, some future challenges and opportunities in this field are proposed. This review promotes the discovery of novel anti‐TQ phosphor materials for LED applications.

AbstractThe fundamental Boltzmann limitation dictates the ultimate limit of subthreshold swing (SS) to be 60 mV dec−1, which prevents the continued scaling of supply voltage. With atomically thin body, 2D semiconductors provide new possibilities for advanced low‐power electronics. Herein, ultra‐steep‐slope MoS2 resistive‐gate field‐effect transistors (RG‐FETs) by integrating atomic‐scale‐resistive filamentary with conventional MoS2 transistors, demonstrating an ultra‐low SS below 1 mV dec−1 at room temperature are reported. The abrupt resistance transition of the nanoscale‐resistive filamentary ensures dramatic change in gate potential, and switches the device on and off, leading to ultra‐steep SS. Simultaneously, RG‐FETs demonstrate a high on/off ratio of 2.76 × 107 with superior reproducibility and reliability. With the ultra‐steep SS, the RG‐FETs can be readily employed to construct logic inverter with an ultra‐high gain ≈2000, indicating exciting potential for future low‐power electronics and monolithic integration.

AbstractStarvation‐dependent differential stress sensitization effect between normal and tumor cells provides a potentially promising strategy to amplify chemotherapy effects and reduce side effects. However, the conventional starvation approaches such as glucose oxidase (Gox)‐induced glucose depletion and nanomedicine‐enabled vascular embolism usually suffer from aggravated tumor hypoxia, systemic toxicity, and unpredictable metabolic syndrome. Herein, a novel “valve‐closing” starvation strategy is developed to amplify the chemotherapy effects via closing the “valve” of glucose transported into tumor cells, which is accomplished by a glucose transporters 1 (GLUT1, valve of glucose uptake) inhibitor (Genistein, Gen) and chemotherapeutic agent (Curcumin, Cur) coloaded hybrid organosilica‐micelles nanomedicine (designated as (Gen + Cur)@FOS) with controllable stability. In vitro and in vivo results demonstrate that (Gen + Cur)@FOS can effectively reduce glucose/adenosine triphosphate levels in tumor cells by inhibiting GLUT1 expression (i.e., “valve‐closing”) to induce the starvation of tumor cells, thus weakening the resistance of tumor cells to apoptosis caused by chemotherapy, and consequently contributing to the remarkably improved antitumor efficiency and minimized side effects based on the stress sensitization effect mediated by GLUT1 inhibition‐induced starvation. This “valve‐closing” starvation strategy provides a promising paradigm for the development of novel nanotherapeutics with amplified chemotherapy effect.

AbstractAs the world population structure has already exhibited an inevitable trend of aging, technical advances that can provide better eldercare are highly desired. Knee osteoarthritis, one of the most common age‐associated diseases, can be effectively treated via total knee arthroplasty (TKA). However, patients are suffering from the recovery process due to inconvenience in post‐hospital treatment. Here, a portable, modular, and wearable brace for self‐assessment of TKA patients’ rehabilitation is reported. This system mainly consists of a force transducer for isometric muscle strength measurement and an active angle sensor for knee bending detection. Clinical experiments on TKA patients demonstrate the feasibility and significance of the system. Specifically, via brace‐based personalized healthcare, the TKA patients’ rehabilitation process is quantified in terms of myodynamia, and a definite rehabilitation enhancement is obtained. Additionally, new indicators, that is, isometric muscle test score, for evaluating TKA rehabilitation are proposed. It is anticipated that, as the cloud database is employed and more rehabilitation data are collected in the near future, the brace system can not only facilitate rehabilitations of TKA patients, but also improve life quality for geriatric patients and open a new space for remote artificial intelligence medical engineering.

AbstractAlternate day fasting (ADF), the most popular form of caloric restriction, has shown to improve metabolic health in preclinical subjects, while intrinsic network underpinning the process remains unclear. Here, it is found that liver undergoes dramatic metabolic reprogramming during ADF, accompanied surprisingly with unique complex II dysfunction attributing to suspended complex II assembly via suppressing SDHAF4, a recently identified assembly factor. Despite moderate mitochondrial complex II dysfunction, hepatic Sdhaf4 knockout mice present intriguingly improved glucose tolerance and systemic insulin sensitivity, consistent with mice after ADF intervention. Mechanistically, it is found that hepatocytes activate arginine‐nitric oxide (NO) biosynthesis axle in response to complex II and citric acid cycle dysfunction, the release of NO from liver can target muscle and adipocytes in addition to its autocrine action for enhanced insulin sensitivity. These results highlight the pivotal role of liver in ADF‐associated systemic benefits, and suggest that targeting hepatic complex II assembly can be an intriguing strategy against metabolic disorders.

AbstractThe large charge overpotential and poor cycling stability triggered by sluggish Li2O2 oxidation kinetics and severe superoxide‐related side reactions greatly restrict the development and application of lithium–oxygen batteries. Finding out high‐efficiency catalysts that can effectively facilitate a highly reversible formation/decomposition of lithium peroxide is still a crucial challenge in the field of Li–O2 batteries. Herein, a soluble catalyst of 2,2'‐Azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) diammonium salt (ABTS) that can promote highly reversible formation and decomposition of Li2O2 during discharge and charge processes is reported for the first time. During discharge, it can capture and couple two LiO2 intermediates via its sulfonate and ammonium ions, and induce the intramolecular disproportionation reaction to produce Li2O2 through ionic microenvironment, which not only prompts the solution‐phase growth of Li2O2, but also restricts the reactivity of LiO2 intermediate, thus significantly alleviating the electrode surface passivation issue and suppressing the superoxide‐related side reactions. During charge, it can quickly transport electrons between the electrode and Li2O2 by serving as a new kind of redox mediator (RM), thus greatly facilitating the Li2O2 oxidation kinetics. As a result, the Li–O2 batteries that incorporate ABTS exhibit outstanding electrochemical performance, low charge overpotential, high discharge capacity, and high cycling stability.
