Maximizing Green Economic Efficiency: The Role of Robot Adoption in Shaping the Future of Manufacturing
Authors: Zhu Mingying 
Published: March 2024

Abstract
Robots play a key role in the manufacturing industry by automating production lines. This study focuses on examining how integrating robots enhance green economic efficiency in manufacturing. We utilize the NDDF model to compute the unified efficiency index (UEI), serving as the core explanatory variable to measure green economic efficiency. Through the application of OLS, 2SLS, Tobit, and IV-Tobit methods, we demonstrate that robots can significantly promote labor productivity, improve capital utilization, and reduce environmental pollution risks. Specifically, a one standard deviation increase in robot installation corresponds to a 29.20% increase in UEI relative to the mean. However, in high energy-consuming and pollutant industries, robots have a limited effect on energy efficiency and emission reduction due to complex production processes and diverse emission sources. Our findings help to provide a theoretical basis to inspire increased investment and promotion of robotics in industrial production, fostering the development of green economy.

Abstract
The aim of this study was to determine the effect of irrigation stress on yield and yield attribute parameter at various growth stage of the broccoli under natural ventilated net-cum-polyhouse. The research experiment was carried out at Junagadh Agricultural University, Junagadh, Gujarat, India for the period of two year 2020-21 and 2021-22. The irrigation stress was imposed 0%, 20%, 40% and 60% of the ETc at initial, mid and end stage of the crop. ETo was calculated by the standard and well accepted FAO-56 method. The yield attribute parameter like stem diameter, plant height, No. of leaves per plant and plant canopy was measured at respective growth stages. However the days taken to harvest, curd diameter, curd weight and yield was measured at time of harvesting. The effect of irrigation stress level on crop growth stages found significant on stem diameter, plant height, No. of leaves per plant, plant canopy, curd diameter, curd weight and yield. The interaction effect of stress imposed on crop growth stage and irrigation stress level on stem diameter, plant height, plant canopy, curd weight and yield was found significant. However, No. of leaves per plant, days taken to harvest and curd diameter was found non significant. The irrigation stress imposed 20% of ETC applied at initial and end stage promote the higher yield in broccoli cultivation. Moreover, the yield was found at par with irrigation stress imposed up to 60% at initial stage and 40% at end stage of the crop. It is advisable to imposed irrigation stress at initial stage and end stage of the broccoli crop during the scare water resources under natural ventilated net-cum-polyhouse. However, irrigation stress imposed at mid stage significantly affect the broccoli yield.
Deep learning based operating parameter decision-making method for optimal penetration rate
Authors: Zhu Yan 
Published: March 2024

Abstract
TBM has become one of the most important equipment for underground excavation due to its effectiveness on both time and economic. However, the efficiency and safety of TBM excavation is highly dependent on the driver's experience. This study proposes a novel deep learning-based intelligent decision-making model for TBM operating parameters. The model consists of a deep learning based TBM operating parameters and TBM performance mapping algorithm and operating parameters decision-making method. The proposed model takes the historical mechanical data of the TBM as input and can suggest optimal operating parameters for TBM excavation in real time. The mapping algorithm can predict the performance of the TBM at any given operating parameter with an average percentage error accuracy of 4.06% for PR and 4.65% for torque. The results show that the proposed decision-making method for operating parameters can increase the PR for about 10% in high excavatability regions and increase about 3% PR in low excavatability regions while reduce energy cost and presumably reduce cutter weariness. This study also analyzes the logic behind the selection of operating parameters by the TBM driver and why the proposed method can achieve better TBM performance than manually driven TBMs.
Hop, Walk or Bound? Limb Proportions in Kangaroos and the Probable Locomotion of the extinct genus Protemnodon
Authors: Jones Billie , Janis Christine Marie 
Published: March 2024

Abstract

Kangaroos (Macropodoidea) display a diversity of locomotor modes, from bounding quadrupedally to hopping bipedally, but hopping has a body mass limit, which was exceeded by a number of extinct taxa. In the Pleistocene a variety of "giant” kangaroos existed: members of the extinct subfamily Sthenurinae have been previously considered to have a type of locomotion different from extant kangaroos (bipedal striding), but the primary locomotor mode of the large species of the extinct "giant" genus Protemnodon, closely related to extant large kangaroos, has undergone little question. Here, the association between limb proportions and locomotor mode across Macropodoidea is assessed by examination of functional limb indices. We show that large (> 100 kg) Protemnodon species are unlike any other known macropodoids; their position in this functional morphospace, along with other evidence on humeral morphology, supports prior hypotheses of a primarily quadrupedal mode of locomotion, likely some sort of bounding.

Abstract
Background
Intravesical bacillus Calmette-Guérin (BCG) is the standard therapy for adjuvant treatment in patients with intermediate- and high-risk superficial bladder cancer. However, the molecular properties associated with BCG therapy have not been fully characterized.
Methods
We reported a comprehensive proteogenomic analysis, including whole-genome sequencing, proteomics, and phosphoproteomics profiling, of 160 non-invasive-muscle bladder cancer (NMIBC) patients treated with BCG.
Results
Proteogenomic integration analysis indicted that tumor mutational burden (TMB), associated with STAT1 activity, was relevant to drug sensitivity. Additionally, our analysis of copy number alterations (CNAs) showed that TLR3 deletion was negatively correlated with response to BCG therapy. TLR3 was validated to regulate the cytokine secretion, and enhance sensitivity to BCG in BC cell lines and organoids. High TMB levels were also associated with improved BCG efficacy across different TLR3 expression subgroups, which holds significant implications. Through proteomic analysis, we identified three subtypes in patients with BCG, reflecting distinct clinical prognosis and biological characteristics. Furthermore, we developed prognostic models with high accuracy to predict the therapeutic response and PFS of NMIBC.
Conclusions
This study provides a rich resource for investigating the mechanisms and indicators of BCG therapy in NMIBC, which can be basis for further improvement of therapeutic response.
Early Stage Thymoma and The Surgical Extent Paradigm
Authors: Kocaman Gökhan , Cangır Ayten Kayı 
Published: March 2024

Abstract

Background
Although the recommended treatment for early stage thymoma without myasthenia gravis is complete thymectomy (CT), limited thymectomy (LT); simply resecting the thymoma by minimally invasive methods is gaining popularity. In this study, we compared the surgical and oncological results of complete and limited thymectomy in non-myasthenic patients with early stage thymoma.
Methods
Non-myasthenic, Masaoka stage I-II, 86 patients who underwent surgical resection for thymoma were included in the study. Complete thymectomy (n:44) included patients who had resection of the thymoma together with the entire thymus and limited thymectomy (n:42) included patients who had resection of the thymoma without remaining thymus. The surgical approach, tumor size, histological type, pathological stage, adjuvant therapy, complications, postop myasthenia gravis, recurrence and death were recorded and compared between groups.
Results
Complete thymectomy group had more WHO type B1-3 tumors, more complications and more deaths than patients in the limited thymectomy group (p = 0.03, 0.018 and 0.023 respectively). Although statistically not significant CT group had more recurrences than LT group (11.4% / 4.8%, p = 0.43). The 10-year freedom from recurrence (FFR) rate in the CT group was 84.8% and in the LT group ıt was 97.6%, the difference was not statistically significant (p = 0.15). None of the factors including surgical extent analysed with univariate and multivariate analysis had a significant effect on FFR.
Conclusions
Limited thymectomy may be a good treatment option for non-myasthenic early stage thymoma patients but randomized controlled trials with long follow-up periods, ideally comparing patients operated with minimally invasive surgery are necessary.
Adaptive Connected Hybrid Beamforming for Energy Efficiency Maximization in Multi-User Millimeter Wave Systems
Authors: Chen Guangyi , Zhang Ruoyu , Miao Chen , Ma Yue , Wu Wen 
Published: March 2024

Abstract
Energy efficiency (EE) is a key enabler for sustainable green millimeter wave (mmWave) communication. However, conventional hybrid beamforming methods suffer from energy efficiency performance loss due to hardware limitations and the connected structure. To overcome these limitations, this work investigates a novel adaptive connected (AC) hybrid beamforming (HBF) design for multi-user mmWave systems. We formulate the problem as an EE maximization problem subject to the constraints of the adaptive connected structure, constant modulus, and power budget. Addressing this complicated non-convex problem, we harness the characteristics of the AC structure and introduce an iterative HBF design algorithm grounded in fractional programming. Numerical results demonstrate the effectiveness and flexibility of the proposed AC-based HBF design in terms of EE enhancement.

Published: March 2024

Abstract
Purpose: Non-muscle invasive bladder cancers (NMIBC) constitute approximately 75% of bladder cancer cases. Primary transurethral resection (TUR) plays a pivotal role in both diagnosis and treatment. However, despite initial resection, tumors are often missed, leaving behind microscopic residual tumors. This study aims to prospectively investigate the surgical margins of tumors, which may serve as a potential source of residual tumors.
Methods: Seventy patients diagnosed with NMIBC who underwent primary TUR were enrolled in this study. Following initial resection, samples were collected from the normal-looking mucosa extending 1 cm beyond the surgical margins. Lesions were categorized as 'no tumor' for benign lesions, 'TCC' for urothelial cancer, and 'UD' for dysplasia. Clinical and pathological features of these groups were compared, and risk factors for detecting TCC in the normal-looking mucosa were analyzed.
Results: The TCC group showed a significantly higher rate of T1 stage tumors compared to the no tumor group, and a significantly higher rate of high-grade (HG) stage tumors compared to the UD group. Moreover, the TCC group had a significantly higher proportion of high-risk patients (85.7%) compared to the other groups, while the no tumor group had a significantly higher proportion of low-risk patients (35.3%) compared to the TCC group (0.0%). Additionally, the TCC group demonstrated a significantly higher rate of carcinoma in situ (CIS) compared to the no tumor group (35.7% vs. 5.9%). TCC formation was associated with T1 stage, HG stage, and the presence of CIS based on univariate analyses.
Conclusion: To minimize residual tumors and prevent recurrence in patients undergoing primary TUR, we advocate for resection of macroscopically visible tumors with at least 2 cm of intact bladder mucosa, thereby enhancing the quality of TUR.

Abstract
Background
Toxoplasmosis is a chronic protozoan parasitic infection that affects nearly one-third of the global population. During the COVID-19 pandemic, cases were observed in patients with COVID-19 and toxoplasmosis. Therefore, this systematic review and meta-analysis aimed to determine the frequency of Toxoplasma gondii exposure in patients with COVID-19.
Methods
A literature search was conducted in six databases (PubMed, Scopus, Embase, Web of Science, ScienceDirect, and Google Scholar) until March 3, 2024. Study selection, quality assessment, and data extraction were performed independently by three investigators. Statistical analysis was performed using R version 4.3, applying a random-effects model. The quality of the included observational studies was assessed using the "JBI-MAStARI".
Results
A total of 5,936 studies were retrieved, 13 of which were included in the final meta-analysis. The sample included a total of 2,947 patients with COVID-19 from four countries, of whom approximately 43.26% were men and 49.41% were women. Among the patients, 1,323 showed evidence of exposure to T. gondii through IgG detection, while 1,302 COVID-19 patients were specifically examined for the presence of T. gondii by IgM detection, and 36 positive cases were identified. The frequency of exposure to T. gondii, determined by the presence of IgG in patients with COVID-19, reached 49% (95% CI: 34-63%; 2,947 participants; 13 studies; I2 = 98%, p < 0.01). In addition, the frequency of exposure to T. gondii, evaluated by IgM presence in patients with COVID-19, was 2% (95% CI: 0-6%; 1,302 participants; 6 studies; I2 = 94%, p < 0.01).
Conclusion
It was shown that almost half of COVID-19 patients had previous exposure to T. gondii through the presence of IgG, and a small percentage, 2%, showed active infection through IgM detection.
Can Route Optimization Enhance the Travel Efficiency of Social Work Faculty Field Liaisons?
Authors: Kodwo-Nyameazea Yale 
Published: March 2024

Abstract

Social work field education comprises a field seminar and an agency field practicum under the supervision of field instructors. Field students and instructors are guided and supported by field faculty liaisons during their field practicum experience. This study used a GIS-supported route optimization/VRP tool to simulate the most cost-efficient way for field liaisons to visit field students and instructors at field practicum sites. The study showed that cumulative travel efficiency improved substantially when the VRP tool allocated field students to field liaisons and preplanned their field visit routes. The simulations revealed that approximately one-quarter of the current practicum site visits were redundant and that only approximately half of the time and distance liaisons currently travel was necessary. Social work programs should consider using route optimization tools to allocate their field students to field liaisons to take advantage of their benefits. Social work programs interested in route optimization can use open-source routing and navigation software applications that can be installed and used for free. They may also collaborate with and access the expertise and resources of academic departments at their universities and colleges that use GIS as part of their curriculum.

Authors: Bizoi Alexandra Codruta , Bizoi Cristian Gabriel 
Published: March 2024

Abstract
Based on Betty Edwards's right-brain drawing methods, this study explored the impact of creative drawing exercises on enhancing cognitive and creative abilities in economics students. Ninety bachelor's and master's students of various nationalities participated in a drawing exercise, followed by a reflection session discussing their experiences and the drawings' significance. The study used a qualitative approach to analyze these experiences and insights. Results showed a marked increase in students' confidence in their creative abilities. Participants reported a refreshed understanding of economic concepts. They overwhelmingly favored the integration of more creative exercises into their economics education, highlighting a beneficial balance between analytical rigor and creative exploration. These findings suggest that combining analytical and artistic techniques in economics pedagogy significantly enhances learning and prepares students for innovative thinking. The promising results encourage further research on the long-term effects of such creative interventions on academic performance and problem-solving in complex economic contexts.

The false alarms and ‘non-impacting’ discharges from event duration monitors (EDM) by a UK water company
Authors: Ford Alex , Boakes Rich , Richardson James , Owens Mike 
Published: March 2024

Abstract
Sewage discharges to aquatic environments present a real danger to human and ecosystem health. Event duration monitors (EDMs) from combined stormwater overflows (CSOs) are now fitted to over 90% of storm overflows in England and Wales. These have transformed our understanding of consented and non-consented discharges of sewage and wastewater from UK water companies. In 2018, Southern Water Services Ltd launched “Beachbuoy” which is an online ‘near’ real-time platform to inform customers when EDMs have been activated at particular CSOs and bathing water sites. Since April 2022, this water company categoried CSO discharges as genuine, genuine but non-impacting, and not genuine (false alarms by EDMs). We analyzed Beachbuoy data to provide an overview of CSO discharges and EDM activity and performance in the region. Across all assets, between December 2020 and February 2023 there were 7,164,656 genuine (impacting and non-impacting) minutes of discharges of which 19% overall were regarded as non-impacting of bathing water locations. Non-impacting discharges from all assets often persisted beyond multiple tidal cycles suggesting the impacts on bathing waters may need to be reevaluated. Discharges classed as ‘not genuine’ (false alarms) were highly variable between CSO for which some recorded false discharges 100% of the time. There were very strong correlations between the triggering of genuine and not genuine discharges and time of the day. Overall, 39% of all total minutes discharged and 14% if discharge events were classified as not genuine. Sewage releases from CSOs were more likely to happen between 7-10 am indicating that earlier morning patterns in human behaviours are substantially impacting the infrastructure's ability to tackle increased capacity in the system through precipitation. We discuss the appropriateness of classifying sewage discharges as ‘non-impacted’ and whether data should also be obtained on false negative discharges (EDMs not activating) as well as false positive discharges (not genuine). We call for better regulation of how this information is presented to the public.
Silicon Photonic Microresonator-Based High-Resolution Line-by-Line Pulse Shaping

Published: March 2024

Abstract

Optical pulse shaping stands as a formidable technique in ultrafast optics, radio-frequency photonics, and quantum communications. While existing systems rely on bulk optics or integrated platforms with planar waveguide sections for spatial dispersion, they face limitations in achieving
finer (few-or sub-GHz) spectrum control. These methods either demand considerable space or suffer from pronounced phase errors and optical losses when assembled to achieve fine resolution. Addressing these challenges, we present a foundry-fabricated
six-channel silicon photonic shaper using microresonator
filter banks with inline phase control and high spectral resolution. Leveraging existing comb-based spectroscopic techniques, we devise a novel system to mitigate thermal crosstalk and enable the versatile use of our on-chip shaper. Our results demonstrate the shaper’s ability to phase-compensate six
comb lines at tunable channel spacings of 3, 4, and 5 GHz. Specifically, at a 3 GHz channel spacing, we showcase the generation of arbitrary waveforms in the time domain. This scalable design and control scheme holds promise in meeting future demands for high-precision spectral shaping capabilities.

Published: March 2024

Abstract

Fretting wear caused by flow-induced vibration is a leading cause of fuel failure in light water nuclear reactors. This study describes a numerical methodology, validated with dedicated experiments, for predicting flow-induced vibrations in cantilever rods exposed to axial water flow, a paradigmatic configuration informative for fuel rods in water-cooled nuclear reactor cores. Utilising strong two-way fluid-structure interaction (FSI) simulations with an efficient computational approach, the study focuses on two key aspects of self-excited FIV: the dominant vibration frequency and the amplitude of the vibration. The former depends on optimising the solid domain and FSI coupling, while the latter hinges on the fluid solver’s ability to accurately replicate unsteady flow behaviour, especially in areas of flow separation. Various URANS turbulence models and divergence numerical schemes were evaluated for their capacity to reproduce the correct unsteady flow behaviour. When the axial flow is directed from the free-end to the fixed-end of the rod, both the Eddy Viscosity Model (EVM) k-ω SST and the Reynolds Stress Model (RSM) by Launder, Reece, and Rodi (LRR) reliably predicted the frequency and amplitude of vibrations for a Reynolds number range between 16.4k and 61.7k. When the axial flow is directed from the fixed end to the free end of the rod, while vibrations frequencies were accurately modelled, replicating precise unsteady flow behaviour proved more challenging. The study underscores the importance of properly resolving the flow in areas of flow separation to achieve accurate unsteady flow behaviour.
