Authors: Dinh Trung Hoa , Le Cong Trinh , Vuong Trung Dung 
Published: January 2024

In this paper, we establish some variational principles for the quantum [Formula: see text]-[Formula: see text]-fidelity. Then, we use quantum [Formula: see text]-[Formula: see text]-fidelity to measure the distance between two quantum orbits. We also study several properties of the [Formula: see text]-[Formula: see text]-weighted right mean which is the unique solution of the least squares problem with respect to the [Formula: see text]-[Formula: see text]-Bures Wasserstein distance. We show that the [Formula: see text]-[Formula: see text]-weighted right mean is a multivariate Lie–Trotter mean.

Authors: Jiang Yong , Hua Zhengwei , Geng Qingli , Li Ning 
Published: January 2024

With the continuous development of antibacterial nanotechnology, nanoparticle-mediated photothermal therapy (PTT) could treat dental implant bacterial infections. Here, a carbon quantum dots (CQDs) loading penicillin (CQDs@penicillin) was constructed as an innovative nanoplatforms to confer promising PTT and delivery of antibiotics. In this nanosystem, CQDs with distinct antibacterial application performance were utilized as an ideal nanocarrier for drug loading, evoking photothermal effects to generate heat under near-infrared (NIR) irradiation. The delivery of penicillin could induce damage to the bacterial cell wall and play a bactericidal effect during the reproduction period of bacterial cells. The antibacterial effects in vitro implied that CQDs@penicillin could significantly kill bacterial cells without severe toxicity. This study proposes a feasible therapeutic strategy for the delivery of antibiotics to dental implant bacterial infections and simultaneously the PTT effect.

Authors: Mukherjee Promit , Mukherjee Rajlaxmi , Sardar Sujit Kumar 
Published: January 2024

The Action graph of a semigroup act was defined by the authors in [P. Mukherjee, R. Mukherjee and S. K. Sardar, Action graph of a semigroup act [Formula: see text] its functorial connection, Categ. Gen. Algebr. Struct. Appl. 18(1) (2023) 43–80] as a combinatorial representation of the acting semigroup. In this paper, we first study some algebraic properties of subacts of a semigroup act which relate graphical properties of the corresponding action graph. We then consider the Leavitt path algebra of action graph and characterize the properties like primality, primitivity, ideal simplicity, etc. Simplicity of the Leavitt path algebra of action graph is found to have a nice connection with the intersection-large subacts of the underlying semigroup act. The notion of extendable subacts of a semigroup act has been introduced and used to characterize the simplicity of Leavitt path algebra for row-finite action graph. Finally, we characterize the simplicity, graded ideal simplicity, purely infinite simplicity of the Leavitt path algebras of a particular class of action graphs namely the Cayley graphs of semigroups. Some of our results in this paper provide suitable generalizations of the existing results on Leavitt path algebra of Cayley graphs as well as of power graphs of finite groups.

Published: January 2024

Background Surgical resection is a mainstay of treatment in high-risk neuroblastoma (HR-NB), but there exists wide variability in perioperative management practices. The aim of this study was to evaluate two standardized adult perioperative enhanced recovery practices (ERPs) in pediatric patients undergoing open resection of abdominal HR-NB. Methods All patients with abdominal HR-NB surgically resected at a free-standing children’s hospital between 12/2010 and 7/2020 were retrospectively reviewed. Perioperative ERPs of interest included avoidance of routine nasogastric tube (NGT) use and the use of neuraxial anesthesia. Primary outcomes included time to enteral intake, urinary catheter use, opioid utilization, and length of stay (LOS). Results Overall, 37 children, median age 33 months (IQR: 20-48 months), were identified. Avoidance of an NGT allowed for earlier feeding after surgery ( P = .03). Neuraxial anesthesia use more frequently required an indwelling urinary catheter ( P < .01) for a longer duration ( P = .02), with no difference in total opioid utilization ( P = .77) compared to patients without neuraxial anesthesia. Postoperative LOS was unaffected by avoidance of routine NGT use ( P = .68) or use of neuraxial anesthesia ( P = .89). Conclusion Children undergoing open resection of abdominal HR-NB initiated diet sooner when an NGT was not left postoperatively, and the need for a urinary catheter was significantly higher in patients who received neuraxial anesthesia. However, these two ERP components did not decrease postoperative LOS. To optimize the postoperative management of NB patients, postoperative NGTs should be avoided, while the benefit of neuraxial anesthesia is less clear as it necessitates the placement of a urinary catheter without decreasing opioid utilization.

Published: January 2024

Background: As the burden of mental health challenges increases globally, delivering mental health education programmes to at-risk groups is critical. Important factors governing the success of health and wellbeing education include the relationships and connections formed between students and those delivering the education. This article reports on the qualitative findings from a mixed-methods study evaluating a mental health wellbeing programme delivered to first-year agricultural students across two universities in New Zealand. Design: The qualitative data that formed the basis of this article involved an exploratory approach utilising semi-structured interviews with participants who had attended a mental health wellbeing programme. Findings: The study found that feelings of connectedness in relation to the programme and the educators, as well as the material provided, improved engagement. In particular, connection was improved through the use of peer educators from within the target community, alongside considerations of timing, promotion and incentives in the delivery of programmes. Conclusions: Relationships and building connections are crucial when delivering health and wellbeing education. These findings have implications for those developing and delivering educational mental health interventions at tertiary institutions in terms of the mechanisms used to support engagement, learning and integration of knowledge.
Effect of milling time on microstructure and hardness of AA7075-15 wt% SiC-1 wt% MWCNT nanocomposite
Authors: Lule Senoz Guzide Meltem 
Published: January 2024

In this study, the effect of ball milling on microstructure and hardness of Al7075 - 15 wt% SiC - 1 wt% MWCNT nanocomposite was investigated as a function of milling time up to 20 h. Mechanically alloyed powders were consolidated by cold pressing followed by sintering at 560°C for 1 h in an argon atmosphere. The structural characterization of nanocomposites was conducted by a X-ray diffractometer (XRD), optical microscopy (OM), scanning electron microscopy (SEM), and grain size analyses. The hardness of samples was measured by using Wolpert Wilson-400 micro-hardness testing equipment comprising of a Vickers indenter. The structural defects of pristine and milled MWCNTs were calculated by using defect and carbon intensity ratio (ID/IG) resulted from Raman spectroscopy. The results indicate that after ball milling, the grain size decreases depending on the milling time, the intermetallic Al4C3 phase is formed as a result of the reaction between the matrix and the MWCNT particles, and the MWCNT structure is destroyed. The finest grain size and highest hardness values were obtained as 483 nm and 134 HV, respectively, after 15 h of grinding.

Published: January 2024

Few studies have examined young people’s attitudes toward death escape acceptance and its relationship to mindfulness. This study addressed this issue and examined the mediating role of emotion regulation. In Study 1, 61 undergraduate students aged 19–22 years participated in a mindfulness intervention program, and the results showed that increasing young people’s levels of mindfulness could improve their attitudes toward death escape acceptance. The Study 2, which recruited 440 young people aged 18–26 years to complete a cross-sectional survey, replicated the main effect and showed that young people’s difficulty in emotion regulation fully mediated the coping effect of mindfulness. These findings suggest that individuals with high levels of mindfulness may have low levels of difficulty in emotion regulation and in turn promote healthy attitudes toward death escape acceptance.

Published: January 2024

Background: Cannabis use among youth is increasing; this study aimed to assess college students’ knowledge, attitude, and expectancies toward cannabis use. Methods: Cross-sectional survey using standardized tools among undergraduate and postgraduate college students in urban Bangalore, India ( N = 405). Results: Ten percent reported past three-month cannabis use, with 1% reporting daily use. Users were significantly older (median age 21, IQR 22,20 [vs. 20, IQR 21,19], p < .001) and belonged to families with higher monthly incomes ( p = .02). Use was significantly higher among males than females (65.9% vs. 34.1%, p = .006) and postgraduate students than undergraduates (51.2% vs. 48%, p = .001). Users were also significantly more favorable toward cannabis use (median score 4, IQR 6,2 [vs. median 3, IQR 4,2], p = .005) and had more positive expectancies from use (median score 2, IQR 3,2 [vs. median 2, IQR 2,0], p = .001). Nearly 30% were unaware that cannabis can affect a person’s ability to drive safely or that it can affect executive functions, including academic performance. Over one-third were unaware of the current legal status of cannabis in India. Overall, 36%, 25%, and 17%, respectively, said that cannabis use is safe when used for recreational purposes, cannabis should be legalized as it helps to relieve stress, and cannabis use among youngsters should be acceptable in society as it is “part of college life.” Conclusion: Findings build on existing literature on cannabis use among college youth in India, which can guide preventive interventions and policies for this vulnerable group.
Soft modularized robotic arm for safe human–robot interaction based on visual and proprioceptive feedback

Published: January 2024

This study proposes a modularized soft robotic arm with integrated sensing of human touches for physical human–robot interactions. The proposed robotic arm is constructed by connecting multiple soft manipulator modules, each of which consists of three bellow-type soft actuators, pneumatic valves, and an on-board sensing and control circuit. By employing stereolithography three-dimensional (3D) printing technique, the bellow actuator is capable of incorporating embedded organogel channels in the thin wall of its body that are used for detecting human touches. The organogel thus serves as a soft interface for recognizing the intentions of the human operators, enabling the robot to interact with them while generating desired motions of the manipulator. In addition to the touch sensors, each manipulator module has compact, soft string sensors for detecting the displacements of the bellow actuators. When combined with an inertial measurement unit (IMU), the manipulator module has a capability of estimating its own pose or orientation internally. We also propose a localization method that allows us to estimate the location of the manipulator module and to acquire the 3D information of the target point in an uncontrolled environment. The proposed method uses only a single depth camera combined with a deep learning model and is thus much simpler than those of conventional motion capture systems that usually require multiple cameras in a controlled environment. Using the feedback information from the internal sensors and camera, we implemented closed-loop control algorithms to carry out tasks of reaching and grasping objects. The manipulator module shows structural robustness and the performance reliability over 5,000 cycles of repeated actuation. It shows a steady-state error and a standard deviation of 0.8 mm and 0.3 mm, respectively, using the proposed localization method and the string sensor data. We demonstrate an application example of human–robot interaction that uses human touches as triggers to pick up and manipulate target objects. The proposed soft robotic arm can be easily installed in a variety of human workspaces, since it has the ability to interact safely with humans, eliminating the need for strict control of the environments for visual perception. We believe that the proposed system has the potential to integrate soft robots into our daily lives.

Published: January 2024

Objective Laparoscopic transabdominal preperitoneal (TAPP) inguinal hernia repair poses certain challenges to less experienced surgeons. This study was performed to compare the clinical outcomes of modified tumescent laparoscopic TAPP (MT-TAPP) inguinal hernia repair versus conventional laparoscopic TAPP (CL-TAPP) inguinal hernia repair. Methods We retrospectively analyzed the perioperative data of patients with inguinal hernias who underwent either MT-TAPP repair (n = 57) or CL-TAPP repair (n = 54) at the General Surgery Department of Nanjing Yimin Hospital from November 2019 to June 2023. Results The durations of the total operation and the preperitoneal space dissection were shorter in the MT-TAPP than CL-TAPP group. The estimated blood loss volume was lower in the MT-TAPP than CL-TAPP group. The visual analogue scale scores recorded at the 12- and 24-hour postoperative time points showed significantly greater reductions in the MT-TAPP than CL-TAPP group. Conclusions Using liquid injection and gauze dissection is both safe and practical. This technique results in a shortened total operation time, less time spent on preperitoneal space dissection, decreased estimated blood loss, and less severe postoperative pain.

Published: January 2024

The primary factors controlling regional gully distribution in mountainous areas are poorly understood. To investigate the spatial characteristics and controlling factors of mountainous gullies at the regional scale, kernel density (KD) estimation, semivariogram, and Geodetector methods were used based on 11 environmental factors of gullies in the Yuanmou dry-hot valley. The results show that (a) gullies are widely but unevenly distributed in the valley, with an average KD of 1.155 km/km2, and gully distribution displays spatial autocorrelation with environmental factors over diverse scales; (b) relief amplitude (Ra), landform type, and slope are the primary factors controlling gully distribution, and land use type, precipitation, and elevation are also important factors; and (c) a high risk of gully erosion occurs in areas with an elevation of more than 1437 m, slope greater than 15°, and Ra greater than 173 m, with grassland vegetation or luvisols and cambisols soil types. These results will not only help to understand the spatial pattern and formation mechanism of gullies at the macroscopic scale but also provide a scientific reference for regional gully management.

Published: January 2024

Background: High tibial osteotomy (HTO) is a successful joint-preserving procedure for the treatment of medial compartment osteoarthritis. Long-term survivorship of HTO ranges from 40% to 85%. There are consistent factors that predict failure. Purpose: To determine the 20-year survival of HTO and identify predictors of failure. Study Design: Case series; Level of evidence, 4. Methods: A total of 100 consecutive patients with medial bone-on-bone arthritis were prospectively studied to provide long-term patient-reported outcome measures after lateral closing-wedge HTO and determine the time to failure. Failure was defined as conversion to arthroplasty (total knee arthroplasty or unicompartmental knee arthroplasty) or revision HTO. Results: At 20 years, HTO survival was determined in 95 patients, and 5 were lost to follow-up. The overall survivorship of HTO at 20 years was 44%. The significant factors that were associated with better survivorship were age <55 years, body mass index <30, and Western Ontario and McMaster Universities Osteoarthritis Index pain score >45. These factors were used to define the favorable candidates. In the favorable candidates, survivorship was 100% at 5 years, after which there was a gradual decline to 62% survival at 20 years. Of those with HTO survival, 32 of 33 (97%) reported satisfaction with surgery, with a mean Knee injury and Osteoarthritis Outcome Score Pain score of 91 and Activities of Daily Living score of 97. Conclusion: HTO is a successful surgical option to treat medial compartment osteoarthritis and prevent the need for arthroplasty in young patients. The most suitable candidates for HTO are aged <55 years, are not obese, and have not progressed to severe symptomatic disability.

Published: January 2024

GF/PP thermoplastic composite components predominantly employ metallic fasteners, leading to corrosion and weight issues. This study utilized an extrusion process to fabricate GF/PP thermoplastic composite rivets with properties akin to laminated panel materials. Through the controlled application of heat and pressure to the rivet ends, a novel connection structure was established. The article fabricated thermoplastic composite joints with varying end configurations and compared them with metallic rivet joints. Emphasizing the convex form, diverse multi-rivet links were crafted for single-lap tensile samples. Integrating tensile tests and strain gauge measurements, this research explored load distribution patterns across diverse rivet quantities and assessed the impact of size on distribution. Furthermore, finite element software was used to dissect the load distribution patterns and failure mechanisms in the multi-riveted connection structure. Drawing from experimental findings, convex GF/PP rivets exhibited an 18% higher tensile load than metallic ones, with a simultaneous 32% weight reduction. In multi-rivet connections, end rivets demonstrated higher load-bearing capacity. Enhanced spacing and plate width improved load distribution, elevating joint load capacity by 7% (spacing 25 mm to 55 mm) and 6% (width 30 mm to 55 mm). The simulation results indicate that increasing the spacing reduces the stress concentration at the first nail location.
Toxicity evaluation of silver nanoparticles synthesized from naringin flavonoid on human promyelocytic leukemic cells and human blood cells
Authors: Soni Deepika , Gandhi Deepa 
Published: January 2024

Increasing applications of silver nanoparticles (AgNPs) in multiple products like cosmetics, medicines, drugs, paints, and other new materials have raised concern for their toxic effects on living beings and the surrounding environment. In the present study, cytotoxicity and genotoxicity of AgNPs synthesized using plant flavonoid (Naringin) as a reducing agent were investigated on human promyelocytic leukemic (HL-60) cells and human blood as an in vitro model. The LC50 of AgNPs was found to be 4.85 µM. Dose-dependent increase in cell death and caspase activity was observed in the presence of AgNPs. The comet assay showed a 60%–70% ( p < .05) increase in tail DNA at 0.48 and 0.96 µM AgNPs. CBMN in PBMCs also confirmed the genotoxic potential of AgNPs-induced DNA damage. AgNPs resulted in 1.5–1.54 fold ( p < .05) increase in the level of ROS in HL-60 cells after 12 h of exposure. AgNP showed toxicity in human cells through ROS generation and cellular damage through membrane dysfunction, caspase activation, apoptosis, and DNA damage.
