Near‐Deterministic Quantum Search Algorithm Without Phase Design
Authors: Wang Zhen , Zhang Kun , Korepin Vladimir 
Published: January 2025

AbstractGrover's algorithm solves the unstructured search problem. Grover's algorithm can find the target state with certainty only if searching one out of four. Designing the deterministic search algorithm can avoid any repetition of the algorithm, especially when Grover's algorithm is a subroutine in other algorithms. Grover's algorithm can be deterministic if the phase of the oracle or the diffusion operator is delicately designed. The precision of the phases could be a problem. A near‐deterministic quantum search algorithm without the phase design is proposed. The algorithm has the same oracle and diffusion operators as Grover's algorithm. One additional component is the rescaled diffusion operator. It acts partially on the database. The success probability of Grover's algorithm is improved by the partial diffusion operator in two different ways. The possible cost is one or two more queries to the oracle. The deterministic search algorithm is also designed when searching one out of eight, sixteen, and thirty‐two.
A critical review of empirical support for trauma‐informed approaches in schools and a call for conceptual, empirical and practice integration
Authors: Watson Kate R. , Astor Ron Avi 
Published: January 2025

AbstractInterest in trauma‐informed approaches in schools is high throughout the US, UK, Australia, Canada and other countries, but the empirical evidence on whole‐school responses to trauma is limited. This conceptual and theoretical review explores relevant literature; outlines existing conceptual models for trauma‐informed organisations, including schools; reviews current evidence for individual components of conceptual models relevant to schools; and considers implications for future research, practice and policy. Four common components were identified in the literature: (a) understanding trauma and making a universal commitment to address it; (b) emphasising physical, emotional and psychological safety for all school members; (c) taking a strengths‐based, whole‐person approach toward staff, students and families; and (d) creating and sustaining trusting, collaborative and empowering relationships among all school constituents. Most of these components have been studied as part of other literature and are not specific to trauma‐informed schools. Practitioners would benefit from shifting to an organisational model for trauma rather than the historical emphasis on interpersonal approaches, toward ensuring that all staff members are trauma‐aware and ‐responsive, and emphasising the creation of healthy, healing schools for all communities.
Adaptive Event‐Triggered Output Feedback Consensus Tracking Control of Multi‐Agent Systems via K‐Filters
Authors: Zhang Tianping , Duan Yanan 
Published: January 2025

ABSTRACTIn this paper, the issue of adaptive event‐triggered output feedback consensus tracking dynamic surface control is discussed for nonlinear multi‐agent systems (MASs) with unmodeled dynamics. The system states are estimated via K‐filters. The unknown nonlinear continuous functions are approximated using radial basis function neural networks (RBFNNs). To lighten the load on communication, an event‐triggered control (ETC) method with a relative threshold is developed. By using command filter backstepping technology, a unique adaptive consensus tracking control strategy is presented. Then, through Lyapunov stability analysis, all signals in the closed‐loop system can be guaranteed to be semi‐globally uniformly ultimately bounded (SGUUB), and the Zeno phenomenon can be avoided. Finally, simulation results validate the effectiveness of the proposed method.

Published: January 2025

ABSTRACTLiDAR‐based SLAM is recognized as one effective method to offer localization guidance in rough environments. However, off‐the‐shelf LiDAR‐based SLAM methods suffer from significant pose estimation drifts, particularly components relevant to the vertical direction, when passing to uneven terrains. This deficiency typically leads to a conspicuously distorted global map. In this article, a LiDAR‐based SLAM method is presented to improve the accuracy of pose estimations for ground vehicles in rough terrains, which is termed Rotation‐Optimized LiDAR‐Only (ROLO) SLAM. The method exploits a forward location prediction to coarsely eliminate the location difference of consecutive scans, thereby enabling separate and accurate determination of the location and orientation at the front‐end. Furthermore, we adopt a parallel‐capable spatial voxelization for correspondence‐matching. We develop a spherical alignment‐guided rotation registration within each voxel to estimate the rotation of vehicle. By incorporating geometric alignment, we introduce the motion constraint into the optimization formulation to enhance the rapid and effective estimation of LiDAR's translation. Subsequently, we extract several keyframes to construct the submap and exploit an alignment from the current scan to the submap for precise pose estimation. Meanwhile, a global‐scale factor graph is established to aid in the reduction of cumulative errors. In various scenes, diverse experiments have been conducted to evaluate our method. The results demonstrate that ROLO‐SLAM excels in pose estimation of ground vehicles and outperforms existing state‐of‐the‐art LiDAR SLAM frameworks.

Authors: Wang Sanxiu , Dai Zhenhao , Lu Qun , Su Chun‐Yi 
Published: January 2025

ABSTRACTMagnetic miniature soft robots hold significant potential in biomedical research, especially for targeted therapy, drug delivery, and cell manipulation. Precise path tracking control is crucial for these robots in complex biomedical applications. Here, we propose a Stanley path tracking control algorithm based on visual feedback for magnetic soft robots. First, a magnetic miniature soft crawling robot was designed and fabricated, and its crawling mechanism was detailed. Next, a simulation framework using the material point method (MPM) was constructed to simulate the movement and deformation of the miniature robot and to verify the proposed crawling mechanism. Finally, visual feedback technology was used to obtain the robot's position and posture, and the Stanley algorithm was applied for path tracking control in crawling mode. The effectiveness of the proposed path tracking control strategy has been verified through multiple experiments. Compared with the traditional Pure Pursuit control method, it has higher robustness and better control accuracy.

Published: January 2025

AbstractThis study introduces a novel dual‐targeting drug delivery system where mitoxantrone (MTO) is encapsulated within horse spleen apoferritin (HsAFr) nanocarriers, modified with biotin to enhance breast cancer targeting. This strategy aims to increase precision and efficacy by engaging multiple receptors in cancer cells. Structural analyses confirmed that the encapsulation and surface modification preserved the protein structure. The system demonstrated high entrapment efficiency (91%) and notable drug loading (9.75%). In vitro, the HsAFr–MTO–Btn complex exhibited greater cytotoxicity against MCF‐7 breast cancer cells compared to free MTO, attributed to enhanced cellular uptake and apoptosis through caspase‐3 activation. These results indicate that HsAFr–MTO–Btn is a promising approach for breast cancer therapy, with potential applications in other difficult‐to‐treat cancers.

Published: January 2025

AbstractGraphitic carbon nitride (g‐CN) is cost‐effective and economically sustainable carbon‐based material with excellent physicochemical properties. Previously, g‐CN has been extensively used as efficient electrode material for the construction of electrochemical sensors, and energy storage applications. The performance of the electrochemical sensors and energy storage devices can be affected by the presence of catalytic properties of the electrode materials. The g‐CN has good catalytic properties and catalytic properties of the g‐CN can be further improved by combining it with nanostructured materials. The g‐CN‐based composite materials may exhibits higher catalytic properties which can associated to the presence of synergistic interactions. Thus, various g‐CN‐based composite materials have been designed and fabricated for electrochemical sensing and energy storage applications. The g‐CN and g‐CN‐based composite materials exhibited excellent performance for the determination of various toxic compounds such as nitro‐aromatics and phenolic compounds. In this mini review article, we summarized the progress in the electrode materials such as g‐CN and its composite materials for the fabrication of electrochemical sensors and energy storage devices. We believe that present mini review article would be beneficial for the researchers working on the fabrication of g‐CN‐based electrode materials for electrochemical sensing and energy storage applications.

AbstractThe molecule of N‐(4‐methoxyphenyl)‐N′‐methyl thiourea (NMTU) was synthesized and characterized through FT‐IR, UV–vis, and 1H, 13C NMR analyses. Its absolute structure was established using single‐crystal X‐ray diffraction (SC‐XRD). The compound crystallizes in the P21/c space group of the monoclinic crystallographic system. Additionally, theoretical evaluations were performed using the density functional theory (DFT) with the B3LYP functional at the 6‐311G(d,p) basis set in the gas phase, showing that the theoretical geometry is in agreement with the X‐ray structural parameters. The analysis of the 3D structure, including dihedral angles, revealed that the compound was non‐planar. The HOMO and LUMO energy values, the global chemical reactivity descriptors, and the molecular electrostatic potential (MEP) were calculated, highlighting the molecule's positive and negative regions, as well as its stability and several electronic characteristics. Hirshfeld surface and 2D fingerprint plots were used to study intermolecular interactions within the crystal. The identified predominant interactions were H⋅⋅⋅H (58.1%), S⋅⋅⋅H/H⋅⋅⋅S (19%), and C⋅⋅⋅H/H⋅⋅⋅C (18.4%). Non‐bonded and weak interactions were investigated using the reduced density gradient (NCI‐RDG). Also, Mulliken charge distribution and natural bond orbital (NBO) analysis for electron transfer were performed at the same theoretical level. Finally The absorption, distribution, metabolism, excretion, and toxicity (ADMET) assessment followed by molecular docking studies were conducted to explore the toxicity and the biological activity of NMTU against mitochondria‐related disease and binding energies with the target protein (PDB ID: 1NTK).

Published: January 2025

AbstractDespite recent extensive studies on mechanochromic luminescence (MCL), rational crafting of new facilely obtainable multifunctional luminescent (MFL) materials from the simple AIEgen skeleton that remain a great challenge due to the impact of the undesirable concentration quenching effect. In this study, we have precisely designed and synthesized a novel donor (D)‐π‐acceptor (A) type of AIE fluorophore (RFTP) by adding one tetraphenylethylene (TPE) unit as a rotator unit to the rofecoxib skeleton by one facile step reaction. RFTP showed a clear mechanochromic behaviors, accompanied by a redshift of 74 nm. In addition, powder X‐ray diffraction (PXRD) and differential scanning calorimetry (DSC) curves indicated the reversible mechanochromic process of RFTP that was caused by the effective phase transition from crystalline state to an amorphous state. Furthermore, RFTP displayed a good optical properties including a large Stokes shift (252 nm) and a typical AIE properties. Meanwhile, density functional theory (DFT) theoretical results support that larger conjugation in RFTP may be the reason for red emissive fluorescence. RFTP can also be effectively localize lipid droplets, positioning it as a useful fluorescent probe for monitoring lipid metabolism in living cells. Taken together, we can provide an efficient strategy to obtain new AIEgens for developing promising multifunctional materials.

Published: January 2025

AbstractIntrinsic low conductivity, poor structural stability, and narrow interlayer spacing limit the development of MnO2 in sodium‐ion (Na+) supercapacitors. This work constructs the hollow cubic Mn‐PBA precursor through an ion‐exchange process to in situ obtain a hollow cubic H‐Ni‐MnO2 composite with Ni doping and oxygen vacancies (OV) via a self‐oxidation strategy. Experiments and theoretical calculations show that the hollow nanostructure and the expanding interlayer spacing induced by Ni doping are beneficial for exposing more reactive sites, synergistically manipulating the Na+ transport pathways. COMSOL simulations reveal the hollow cube can buffer the deformation stress generated by the electrochemical reaction, leading to the stable Na+ storage ability of the H‐Ni‐MnO2 electrode. Meanwhile, Ni doping induces a rich abundance of OV at the molecular level, triggering intense interfacial electronic interactions and regulating the Na+ adsorption energy to improve Na+ reaction kinetics. The prepared H‐Ni‐MnO2 electrode exhibits superior rate capability (80.6% at 10 A g−1) and high‐rate long‐term cycle stability (92.7% retention after 10 000 cycles at 10 A g−1). In addition, the assembled hybrid supercapacitor demonstrates outstanding energy/power density output and application prospects. This work provides a novel approach to the structure and function design of MnO2‐based materials for advanced Na+ storage.

Published: January 2025

AbstractThis study investigates the innovative integration of Portland limestone cement (PLC) and date palm ash (DPA) in preplaced aggregate concrete (PAC) grouts, addressing the urgent need for sustainable construction materials with a lower carbon footprint. With the construction industry contributing significantly to global CO2 emissions, utilizing agricultural by‐products like DPA offers an eco‐friendly alternative while mitigating waste disposal challenges. The research evaluates single, binary, and ternary binders incorporating supplementary cementitious materials such as silica fume (SF) and metakaolin to optimize PAC's mechanical properties. Findings reveal that binary grouts with PLC and 10% SF achieved the highest compressive strength (68.3 MPa), outperforming traditional mixtures by 40%. Microstructural analysis confirmed that DPA enhances matrix density and reduces pore size, contributing to improved durability. Recommendations include further exploration of DPA's role in reducing cement content and promoting resource efficiency. The findings highlight PLC and DPA as viable components for greener construction, advancing PAC's potential as a sustainable concrete for structural applications.

Published: January 2025

AbstractNeedle‐punched carbon/carbon composites (NP C/Cs) are advanced materials widely used in aerospace applications. The needle‐punching technique improves the structural integrality of carbon‐fiber plies; however, it also introduces many defects affecting the mechanical behavior of NP C/Cs. To investigate the behavior of needle‐punched carbon/carbon composites under bending loads, a circular‐arc beam element with a needle‐hole defect is developed to model the punched carbon fibers and an extended spring element is suggested to model the matrix. This model allows quick predictions of the bending modulus, strength and progressive damage of NP C/Cs. It is shown that efficient numerical predictions agree well with the experimental results, thus validating the proposed method.

The bias conjecture for elliptic curves over finite fields and Hurwitz class numbers in arithmetic progressions
Authors: Kane Ben , Pujahari Sudhir , Yang Zichen 
Published: January 2025

AbstractIn this paper, we consider a version of the bias conjecture for second moments in the setting of elliptic curves over finite fields whose trace of Frobenius lies in a fixed arithmetic progression. Contrary to the classical setting of reductions of one-parameter families over the rationals, where it is conjectured by Steven J. Miller that the bias is always negative, we prove that in our setting the bias is positive for a positive density of arithmetic progressions and negative for a positive density of arithmetic progressions. Along the way, we obtain explicit formulas for moments of traces of Frobenius of elliptic curves over finite fields in arithmetic progressions and related moments of Hurwitz class numbers in arithmetic progressions, the distribution of which are of independent interest.
CMV IgG in the blood is not associated with hepatitis but correlates with poor outcomes in immunotherapy treated melanoma patients

Published: January 2025

Abstract
Cytomegalovirus (CMV) infection or reactivation in immune-compromised individuals can lead to a wide range of severe complications including hepatitis. However, its relation with immune checkpoint inhibitors (ICIs) induced hepatitis (ICI-hepatitis) and tumor responses in advanced melanoma patients remains unclear. Hundred and ninety metastatic cutaneous melanoma patients (mCM) who received ICI treatment, with CMV IgG or IgM information available at baseline, were included in the study (Cohort 1). Clinical characteristics and immune cell count in the blood were retrieved from medical records. In addition, anti-CMV IgG and IgM were measured in pre and on-treatment serum samples from 49 advanced skin cancer patients using ELISA (Cohort 2). In the event of a positive anti-CMV IgM, further analysis with PCR was performed. Univariate and multivariate analysis was used to assess the relationship between CMV IgG or IgM and ICI-hepatitis tumor outcomes. Twenty-one patients (11%) developed hepatitis during ICI treatment (Cohort 1). ICI-hepatitis was significantly associated with disease control rate (DCR; p = 0.017) and longer progression-free survival (PFS; p = 0.008) in mCM patients. Detection of CMV IgG or IgM antibodies were not associated with ICI-hepatitis (p > 0.05). However, increased CMV IgG values at baseline correlated with disease progression (p = 0.047) and shorter PFS (p = 0.081). In addition, increased CMV IgG values were associated with reduced levels of monocytes (p = 0.005), eosinophils (p = 0.062), and neutrophils (p = 0.065) in the blood. In summary, anti-CMV IgG or IgM in the blood may not be associated with ICI-hepatitis, but high anti-CMV IgG at baseline indicates poor outcomes in ICI-treated mCM patients.
