The treatment of biodegradable plastics through composting has garnered increasing attention. This study aimed to investigate the effects of Biochar FN1 bacteria and ferrous sulfate on nitrogen retention, greenhouse gas emissions, and degradable plastics during composting and to elucidate their synergistic mechanisms on microbial communities. Compared with the control, applying biochar-loaded FN1 bacteria composites combined with Ferrous sulfate (SGC) markedly accelerated organic matter degradation and reduced cumulative CO and NH emissions.

NO-N transformation, the vital biological process, determines nitrogen removal and retention in aquatic environment. Suspended sediment (SPS) ubiquitous in freshwater ecosystems can accelerate the transitions from aerobic to anoxic states, inevitably impacting NO-N transformation. To elaborate on the microbial mechanism by which SPS content affected NO-N transformation, we explored nitrogen removal and retention, microbial communities, co-occurrence networks, and electron transfer behavior under different SPS content during the aerobic-anoxic transition.

The complex life cycle traits of amphibians make them especially sensitive to environmental change, and their ongoing conservation requires the maintenance of suitable habitat that accounts for such life cycle characteristics which may impacted by local environmental dynamics arising from climate change and human disturbance. Many existing studies on amphibian habitats disregard this important issue, leading to uncertainty in managing critical habitats. The application of appropriate conservation practices is therefore constrained by the fact that the major factors influencing amphibian habitats, and their spatio-temporal dynamics at different life stages, are poorly understood.

Anti-seizure medications and deep brain stimulation are widely used therapies to treat seizures; however, both face limitations such as resistance and the unpredictable nature of seizures. Recent advancements, including responsive neural stimulation and on-demand drug release, have been developed to address these challenges. However, a gap remains, as electrical stimulation provides only transient effects while medication has a delayed onset.

Accelerated quadratic penalty dynamic approaches with applications to distributed optimization.

Neural Netw

December 2024

Pittsburgh Institute, Sichuan University, Chengdu, Sichuan, 610207, China. Electronic address:

In this paper, we explore accelerated continuous-time dynamic approaches with a vanishing damping α/t, driven by a quadratic penalty function designed for linearly constrained convex optimization problems. We replace these linear constraints with penalty terms incorporated into the objective function, where the penalty coefficient grows to +∞ as t tends to infinity. With appropriate penalty coefficients, we establish convergence rates of O(1/t) for the objective residual and the feasibility violation when α>0, and demonstrate the robustness of these convergence rates against external perturbation.

Visual question generation involves the generation of meaningful questions about an image. Although we have made significant progress in automatically generating a single high-quality question related to an image, existing methods often ignore the diversity and interpretability of generated questions, which are important for various daily tasks that require clear question sources. In this paper, we propose an explicitly diverse visual question generation model that aims to generate diverse questions based on interpretable question sources.

College of Computer Science and Engineering, Shandong University of Science and Technology, Qingdao 266590, China. Electronic address:

Currently, for obtaining more accurate counts, existing methods primarily utilize RGB images combined with features of complementary modality (X-modality) for counting. However, designing a model that can adapt to various sensors is still an unsolved issue due to the differences in features between different modalities. Therefore, this paper proposes a unified fusion framework called CMFX for RGB-X crowd counting.

A sparse and wide neural network model for DNA sequences.

Neural Netw

December 2024

Norwegian University of Science and Technology, Trondheim, Norway; Jinhua Institute of Zhejiang University, Hangzhou, China.

Accurate modeling of DNA sequences requires capturing distant semantic relationships between the nucleotide acid bases. Most existing deep neural network models face two challenges: (1) they are limited to short DNA fragments and cannot capture long-range interactions, and (2) they require many supervised labels, which is often expensive in practice. We propose a new neural network model called SwanDNA to address the above challenges.

In the dorsal striatum (DS), the direct- and indirect-pathway striatal projection neurons (dSPNs and iSPNs) play crucial opposing roles in controlling actions. However, it remains unclear whether and how dSPNs and iSPNs provide distinct and specific contributions to decision-making, a process transforming sensory inputs to actions. Here, we perform causal interrogations on the roles of dSPNs and iSPNs in the posterior DS (pDS) in auditory-guided decision-making.

High expression of immune checkpoint molecule B7-H3 (CD276) in many cancer types makes it a promising immunotherapeutic target. Both coinhibitory and costimulatory effects of B7-H3 in tumors have been demonstrated, but the mechanism of B7-H3 immune response under dual effects is open to question. B7-H3 is crucially involved in the migration and invasion, angiogenesis, metabolism and chemotherapy resistance of prostate cancer.

December 2024

State Key Laboratory of Crop Genetics & Germplasm Enhancement and Utilization, Zhongshan Biological Breeding laboratoryr, Nanjing Agricultural University, Nanjing, 210095, China.

Plant lipid transfer proteins (LTPs) are distinguished by their capacity to facilitate lipid transport in vitro between membranes. This includes the transportation of lipid constituents from the tapetum to the microspore, thereby playing a pivotal role in the synthesis and construction of the pollen wall, encompassing the formation of the pollen aperture. However, our understanding of LTPs and their role in pollen aperture formation in rice remains limited.
