High-dimensional multipartite entanglement plays a crucial role in quantum information science. However, existing schemes for generating such entanglement become complex and costly as the dimension of quantum units increases. In this Letter, we overcome the limitation by proposing a significantly enhanced linear optical heralded scheme that generates the d-level N-partite Greenberger-Horne-Zeilinger (GHZ) state with single-photon sources and linear operations.

Electrochemical impedance spectroscopy (EIS) serves as a non-invasive technique for assessing cell status, while mechanical stretching plays a pivotal role in stimulating cells to emulate their natural environment. Integrating these two domains enables the concurrent application of mechanical stimulation and EIS in a stretchable cell culture system. However, challenges arise from the difficulty in creating a durable and stable stretchable impedance electrode array.

Currently, it is a significant challenge to achieve long-term cyclability and fast chargeability in lithium-ion batteries, especially for the Ni-based oxide cathode, due to severe chemo-mechanical degradation. Despite its importance, the fast charging long-term cycling behaviour is not well understood. Therefore, we comprehensively evaluate the feasibility of fast charging applications for Co-free layered oxide cathodes, with a focus on the extractable capacity and cyclability.

Background: Vascular cognitive impairment/dementia (VD) is the second most prevalent cause of dementia following Alzheimer's disease (AD). VD is characterized by the progression of white matter hyperintensity burden (WMH) and associated neurodegeneration. GFAP, a biomarker for reactive astrogliosis, is associated with Aβ pathology and mediates tau-pathology in preclinical AD.

Background: Dysregulation of cholesterol metabolism contributes to the increase of cerebral vascular diseases, favoring the development of dementia. In this sense, high levels of high-density lipoprotein (HDL) are considered protective against the outcomes associated with cardiovascular diseases. However, little is known about the effect of plasma HDL levels to alterations of cerebral volume in non-vascular AD and vascular AD individuals.

Lattice volume changes in Li-ion batteries active materials are unavoidable during electrochemical cycling, posing significant engineering challenges from the particle to the electrode level. In this study, we present an elastic framework coating designed to absorb and reversibly release strain energy associated with particle volume changes, thereby enhancing mechanical resilience at both the particle and electrode levels. This framework, composed of multiwalled carbon nanotubes (MWCNTs), is applied to nickel-rich LiNiCoMnO (NCM9055) cathodes at a low loading of 0.

Bacterial species adapt to cold environments with diverse molecular mechanisms enabling their growth under low ambient temperature. The emergence of cold-adapted species at macro-evolutionary scale, however, has not been systematically explored. In this study, we performed phylogenetic analysis on the growth temperature traits in the genera that occupy broad environmental and host niches and contain known cold-adapted species.

Recent advances in mass transfer technology are expected to bring next-generation micro light-emitting diodes (µLED) displays into reality, although reliable integration of the active-matrix backplane with the transferred µLEDs remains as a challenge. Here, the µLED display technology is innovated by demonstrating pixel circuit-integrated micro-LEDs (PIMLEDs) and integrating them onto a transparent glass substrate. The PIMLED comprises of low-temperature poly-silicon transistors and GaN µLED.

The utilization of redox mediators (RMs) in lithium-oxygen batteries (LOBs) has underscored their utility in high overpotential during the charging process. Among the currently known RMs, it is exceptionally challenging to identify those with a redox potential capable of attenuating singlet oxygen (O) generation while resisting degradation by reactive oxygen species (ROS), such as O and superoxide (O ). In this context, computational and experimental approaches for rational molecular design have led to the development of 7,7'-bi-7-azabicyclo[2.

Peucedanum japonicum (PJ), a member of the Apiaceae family, is widely distributed and cultivated in East Asian countries for edible and functional foods. In this study, we compared the plastid genomes (plastomes) and 45S nuclear ribosomal DNA (45S nrDNA) simultaneously from 10 PJ collections. Plastome-based phylogenetic analysis showed that the PJ accessions were monophyletic within the genus Peucedanum.

A central tenet of cognitive neuroscience is that humans build an internal model of the external world and use mental simulation of the model to perform physical inferences. Decades of human experiments have shown that behaviors in many physical reasoning tasks are consistent with predictions from the mental simulation theory. However, evidence for the defining feature of mental simulation - that neural population dynamics reflect simulations of physical states in the environment - is limited.

In modern digital systems, sequential logic circuits store and process information over time, whereas combinational logic circuits process only the current inputs. Conventional sequential systems, however, are complex and energy-inefficient due to the separation of volatile and nonvolatile memory components. This study proposes a compact, nonvolatile, and reconfigurable van der Waals (vdW) ferroelectric field-effect transistor (FeFET)-based sequential logic-in-memory (S-LiM) unit that performs sequential logic operations in two nonvolatile states.

The electrical resistivity of conventional metals such as copper is known to increase in thin films as a result of electron-surface scattering, thus limiting the performance of metals in nanoscale electronics. Here, we find an unusual reduction of resistivity with decreasing film thickness in niobium phosphide (NbP) semimetal deposited at relatively low temperatures of 400°C. In films thinner than 5 nanometers, the room temperature resistivity (~34 microhm centimeters for 1.

Enzymes capable of breaking down polymers have been identified from natural sources and developed for industrial use in plastic recycling. However, there are many potential starting points for enzyme optimization that remain unexplored. We generated a landscape of 170 lineages of 1894 polyethylene terephthalate depolymerase (PETase) candidates and performed profiling using sampling approaches with features associated with PET-degrading capabilities.

Carbapenem-resistant complex (CR-ECC), which is rapidly increasing as the cause of nosocomial infections, has limited treatment options. The aim of this study is to investigate the microbiological and clinical traits and molecular epidemiology of isolates of CR-ECC and provide guidance for antibiotic selection in clinical practice. Clinical CR-ECC isolates (ertapenem MIC ≥ 2 mg/L) were collected from 2021 to 2022.

Interstitial quasi-atomic electrons (IQEs) in the quantized energy levels of positively charged cavities possess a substantial own magnetic moment and control the magnetism of crystalline electrides depending on the interaction with surrounding cations. However, weak spin-orbit coupling and gentle exchange interaction restricted by the IQEs preclude a large magnetic anisotropic, remaining a challenge for a hard magnetism. It is reported that 2D [ReC]·2e electrides (Re = Er, Ho, Dy, and Tb) show the permanent magnetism in a ferrimagnetic ground state, mimicking the ferrites composed of magnetic sublattices with different spin polarizations.

Metal electrode deposition is universally adopted in the community for optoelectronic device fabrication, inducing hybridization at electrode interfaces, and allows efficient extraction or injection of photocarriers. However, hybridization-induced midgap states increase photocarrier recombination pathways, creating a paradoxical trade-off. Here, we discovered that efficient photocarrier extraction and a long photocarrier lifetime can be achieved simultaneously in MoS/van der Waals Au contact, minimizing photocarrier loss at the interface.

In this study, a tetradentate Pt(II) complex designed to have -heterocyclic carbene ligands modified with an anchor-shaped 2,6-diisopropylphenyl (dip) group is described to enhance molecular rigidity for narrow emission and high efficiency. The tetradentate ligand with the dip group significantly hinders steric interactions and restricts π-conjugation from benzocarbene, leading to shallow lowest unoccupied molecular orbital levels and a consequent reduction in the triplet metal-to-ligand charge transfer character. These structural modifications result in narrow emission spectra and enhanced efficiency for blue organic light-emitting diodes (OLEDs) over wide doping concentration ranges.
