Two-dimensional fully ferroelectric-gated hybrid computing-in-memory hardware for high-precision and energy-efficient dynamic tracking.

Computing in memory (CIM) breaks the conventional von Neumann bottleneck through in situ processing. Monolithic integration of digital and analog CIM hardware, ensuring both high precision and energy efficiency, provides a sustainable paradigm for increasingly sophisticated artificial intelligence (AI) applications but remains challenging. Here, we propose a complementary metal-oxide semiconductor-compatible ferroelectric hybrid CIM platform that consists of Boolean logic and triggers for digital processing and multistage cell arrays for analog computation.

Linearly Polarized Broadband Emission and Multiwavelength Lasing in Solution-Processed Quantum Dots.

A miniature laser with linear polarization is a long sought-after component of photonic integrated circuits. In particular, for multiwavelength polarization lasers, it supports simultaneous access to multiple, widely varying laser wavelengths in a small spatial region, which is of great significance for advancing applications such as optical computing, optical storage, and optical sensing. However, there is a trade-off between the size of small-scale lasers and laser performance, and multiwavelength co-gain of laser media and multicavity micromachining in the process of laser miniaturization remain as significant challenges.

Agricultural drought research knowledge graph reasoning by using VOSviewer.

Drought seriously affects agricultural systems and food security. While previous researchers have explored the causes, monitoring, and impacts of drought on agriculture, no systematic investigations into the development of agriculture drought (AD) and its relationships with related knowledge have been conducted. This study assessed existing publications, particularly those conducted between 2020 and 2023.

Luminescence, energy transfer, colour modulation and up-conversion mechanisms of Yb, Tm and Ho co-doped YMoO.

A series of novel up-conversion luminescent Yb/Ln (Tm, Ho, Tm/Ho)-doped YMoO (YMO) nanocrystals were synthesized using the sol-gel method. The consistent spherical morphology of the nanocrystals with different doping ratios was found to be profiting from the homogenisation and rapid agglomeration of the composition in the gel state and calcining process. The X-ray diffraction (XRD) and field-emission scanning electron microscope images were employed to confirm perfect crystallinity and uniform morphology.

Investigation of crystal field effects for the spectral broadening of Yb-doped Lu Y O sesquioxide crystals.

The investigation of crystal field effects is significant for elucidating the spectral characteristics of Yb-doped sesquioxide crystals for ultrafast laser generation. The narrow spectra of Yb-doped single sesquioxide crystals limit the generation of ultrafast lasers; in this study, the Y ions were introduced into LuO single crystals by the employment of ion replacement to broaden the spectra. To analyze the spectral broadening, the responsible crystal field parameters (CFPs) were calculated.

Projection of key meteorological hazard factors in Xiongan new area of Hebei Province, China.

It is of great importance to explore the future spatiotemporal dynamics of key meteorological hazard factors in Xiongan New Area, an area of great strategic significance under construction in China. Based on 6.25 km high-resolution downscaling projection data under RCP4.

Classification of Chinese vinegar varieties using electronic nose and fuzzy Foley-Sammon transformation.

Due to the difference of raw materials and brewing technology, the quality and flavours of vinegar are different. Different kinds of vinegar have different functions and effects. Therefore, it is important to classify the vinegar varieties correctly.

Proteomics Analysis of Colostrum Samples from Sows Housed under Different Conditions.

This study investigated the proteomic characteristics of colostrum for sows housed under different conditions. Among 12 gilts, four were housed in a gestation-crate and farrowing-crate combined housing system (CC) as controls, four were housed in a gestation-pen and farrowing-pen combined housing system (PP), and four were housed in a gestation-pen and farrowing-crate combined housing system (PC). Differentially expressed proteins in the colostrum (PP versus CC, and PC versus CC) were screened by proteomics technology, and bioinformatics analysis was then performed.

Assessing multi-risk characteristics of heat and cold stress for rice across the southern parts of China.

Rice (Oryza sativa) growth is always threatened by heat as well as cold stress, when it is exposed to natural environment. Heat growing degree hours (HGDH) and cold growing degree hours (CGDH1 and CGDH2) were firstly proposed to quantify heat and cold stress occurred during different growing stages. Information diffusion method was effectively used to fit the distribution and estimate probability of single stress at each station, with an advantage of no limitation in data series.

Fluorometric determination of antioxidant capacity in human plasma by using upconversion nanoparticles and an inner filter effect mechanism.

The balance between free oxygen radicals and antioxidant defense systems is usually assessed by an antioxidant capacity assay. A rapid and sensitive antioxidant capacity assay is described here. It is making use of NaYF:Yb/Er@NaYF core-shell upconversion nanoparticles (UCNPs) and potassium permanganate (KMnO).

Demonstration of a White Laser with V C MXene-Based Quantum Dots.

Multicolor photoluminescence over the full visible color spectrum is critical in many modern science and techniques, such as full-color lighting, displays, biological and chemical monitoring, multiband communication, etc., but the ultimate white lasing especially on the nanoscale is still a challenge due to its exacting requirements in the balance of the gain and optical feedback at different wavelengths. Recently, 2D transition metal carbides (MXenes) have emerged, with some superior chemical, physical, and environmental properties distinguishing them from traditional 2D materials.

A pilot study on differential expression of microRNAs in the ventromedial prefrontal cortex and serum of sows in activity restricted crates or activity free pens.

Objective: Physical activity restriction in sows may lead to behavioral abnormalities and affective disorders. However, the psychophysiological state of these sows is still unclear. As miRNAs can be used as effective markers of psychopathy, the present study aimed to assess the difference in microRNA expression between the long-term activity restricted sows and activity free sows, thus contributing to the understanding of abnormal sow behaviors.

Optical-magnetic bifunctional properties and mechanistic insights on upconversion of NaYF:Yb,Ho,Tm@NaGdF with a tunable nanodumbbell morphology.

The energy-upconversion of lanthanide-doped nanoparticles with a core-shell structure can be utilized to enhance and tune optical properties and can generate multifunctionality in a single system. Herein, the core-shell nanoparticles NaYF:Yb,Ho,Tm@NaGdF were prepared by thermally decomposing lanthanide acetylacetonate precursors. Through modifying the molar ratio of the core and shell, nanodumbbell-shaped particles with different sizes and morphologies were precisely synthesized.

Effect of straw enriched environment on behaviors of nursery piglets reared in the farrowing pens.

The aim of the present study was to study the effects of straw enriched environment on behaviors of nursery piglets reared in the farrowing pens. Fourteen litters (Large White x Landrace) weaned at 35 days of age were reared in the modified farrowing pens, flatdecks (F) or straw enriched pens (P), until 70 days of age. The behavior was observed from 7 to 10 weeks of age.

Graphene's cousin: the present and future of graphane.

The so-called graphane is a fully hydrogenated form of graphene. Because it is fully hydrogenated, graphane is expected to have a wide bandgap and is theoretically an electrical insulator. The transition from graphene to graphane is that of an electrical conductor, to a semiconductor, and ultimately to an electrical insulator.
