Context-Aware Trust Prediction for Optimal Routing in Opportunistic IoT Systems.

The Social Opportunistic Internet of Things (SO-IoT) is a rapidly emerging paradigm that enables mobile, ad-hoc device communication based on both physical and social interactions. In such networks, routing decisions heavily depend on the selection of intermediate nodes to ensure secure and efficient data dissemination. Traditional approaches relying solely on reliability or social interest fail to capture the multifaceted trustworthiness of nodes in dynamic SO-IoT environments.

Selective nitrogen removal in constructed wetlands enhanced by MnX-GAC (X=Fe or Zn): Performance, mechanism and removal pathway.

Constructed wetlands (CWs) are widely used to treat wastewater containing nitrogenous due to their low energy consumption, low maintenance costs, and significant ecological benefits. However, they face challenges such as low denitrification efficiency and greenhouse gas emissions during treatment. Enhancing the synergistic performance of the "substrate-microorganism" system within CWs is considered an effective way to address these problems.

A Novel Allele in the Promoter of Decreases Gene Expression and Confers Lower Apparent Amylose Contents in Rice ( L.).

is the key gene that controls amylose content (AC), and various alleles have been found in rice populations. is the major allele in and produces moderate AC (15~18%). It was recently found that editing the promoter of could produce a series of alleles that have different Wx activities.

Rice transcriptional repressor OsTIE1 controls anther dehiscence and male sterility by regulating JA biosynthesis.

Proper anther dehiscence is essential for successful pollination and reproduction in angiosperms, and jasmonic acid (JA) is crucial for the process. However, the mechanisms underlying the tight regulation of JA biosynthesis during anther development remain largely unknown. Here, we demonstrate that the rice (Oryza sativa L.

Selection and Validation of 48 KASP Markers for Variety Identification and Breeding Guidance in Conventional and Hybrid Rice (Oryza sativa L.).

Background: Breeding of conventional and hybrid rice (Oryza sativa L.) have solved hunger problems and increased farmers' income in the world. Molecular markers have been widely used in marker-assisted breeding and identification of larger numbers of different bred varieties in the past decades.

Variation in arsenic accumulation and translocation among 74 main rice cultivars in Jiangsu Province, China.

Arsenic (As) is a ubiquitous carcinogen and environmental toxin. In China, rice consumption is a major dietary source of inorganic As. Thus, the development of strategies to decrease As accumulation in rice is of considerable importance.

Genotypic Variation in Nickel Accumulation and Translocation and Its Relationships with Silicon, Phosphorus, Iron, and Manganese among 72 Major Rice Cultivars from Jiangsu Province, China.

Nickel (Ni) is a ubiquitous environmental toxicant and carcinogen, and rice is a major dietary source of Ni for the Chinese population. Recently, strategies to decrease Ni accumulation in rice have received considerable attention. This study investigated the variation in Ni accumulation and translocation, and also multi-element (silicon (Si), phosphorus (P), iron (Fe), and manganese (Mn)) uptake and transport among 72 rice cultivars from Jiangsu Province, China, that were grown under hydroponic conditions.

Rice tocopherol deficiency 1 encodes a homogentisate phytyltransferase essential for tocopherol biosynthesis and plant development in rice.

RTD1 encodes a homogentisate phytyltransferase catalyzing a key step in rice tocopherol biosynthesis, confers cold tolerance and regulates rice development by affecting the accumulation of DELLA protein SLENDER RICE1. Tocopherols are one of the most important lipid-soluble antioxidants having indispensable roles in living organisms. The physiological functions of tocopherols have been comprehensively characterized in animals and artificial membranes.

Trapped spoof surface plasmons with structured defects in textured closed surfaces.

We demonstrate that a defect unit in periodic textured closed surfaces is able to trap spoof surface plasmons (SPs) into a deep subwavelength scale. The resonant frequency of a trapped spoof SP can be tuned freely by properly tailoring the dimension of the defect unit. By introducing multiple defect units with different dimensions at different positions of the textured closed surfaces, the spoof SPs with different frequencies trapped effectively at desired places are also demonstrated.

Finite-time synchronization for recurrent neural networks with discontinuous activations and time-varying delays.

In this paper, we study the finite-time synchronization problem for recurrent neural networks with discontinuous activations and time-varying delays. Based on the finite-time convergence theory and by using the nonsmooth analysis technique, some finite-time synchronization criteria for the considered neural network model are established, which are new and complement some existing ones. The feasibility and effectiveness of the proposed synchronization method are supported by two examples with numerical simulations.

Robust signatures detection of Majorana fermions in superconducting iron chains.

We theoretically propose an optical means to detect Majorana fermions in superconducting iron (Fe) chains with a hybrid quantum dot-nanomechanical resonator system driven by two-tone fields, which is very different from the current tunneling spectroscopy experiments with electrical means. Based on the scheme, the phenomenon of Majorana modes induced transparency is demonstrated and a straightforward method to determine the quantum dot-Majorana fermions coupling strength is also presented. We further investigate the role of the nanomechanical resonator, and the resonator behaving as a phonon cavity enhances the exciton resonance spectrum, which is robust for detecting of Majorana fermions.

Synthesis and antitumor activity of novel nitrogen mustard-linked chalcones.

A series of nitrogen mustard-linked chalcones were synthesized and evaluated for their antitumor activity in vitro against the K562 and HepG2 cell lines. The aldol condensation of [N,N-bis(chloroethyl)-3-amino]-acetophenone (2) with aromatic aldehydes afforded the nitrogen mustard-linked chalcones. Among the analogs tested, compounds 5e and 5k exhibited significant anti-proliferation activities against K562 cells with IC50 values of 2.
