Aims. The clusters Abell 2061 and Abell 2067 in the Corona Borealis supercluster have been studied at different radio frequencies and are both known to host diffuse radio emission. The aim of this work is to investigate the radio emission between them, whose presence is suggested by low-resolution observations.

Methods. We analysed deep LOw Frequency ARray (LOFAR) High Band Antenna (HBA) observations at 144 MHz to follow up on the possible inter-cluster filament suggested by previous 1.4 GHz observations. We investigated the radial profiles and the point-to-point surface-brightness correlation of the emission in Abell 2061 with radio and X-ray observations to describe the nature of the diffuse emission.

Results. We report the detection of diffuse radio emission on an 800 kpc scale, which is more extended than previously known, reaching beyond the radio halo in Abell 2061 towards Abell 2067 and over the separation outside the two clusters R500 radii. We confirm the presence of a radio halo in A2061, while we do not find evidence of diffuse emission in Abell 2067. The surface-brightness profile from the centre of A2061 shows an excess of emission with respect to the azimuthally averaged radio halo profile and X-ray background. We explored three different dynamical scenarios to explain the nature of the diffuse emission. Additionally, we analysed a trail of emission of ∼760 kpc between the radio halo and radio relic in Abell 2061.

Conclusions. This dynamically interacting, pre-merger system closely resembles the two other cluster pairs where radio bridges connecting the radio halos on Megaparsecs scales have been detected. The diffuse emission extends beyond each cluster R500 radius, but in this unique case the absence of the radio halo in Abell 2067 is likely the reason for the observed ‘gap’ between the two systems. However, the point-to-point correlation results are challenging to explain. The classification of the emission remains unclear, and detailed spectral analysis and further X-ray observations are required to understand the origin of the diffuse emission.

This paper presents the results of a joint radio and gamma-ray timing campaign on the nine millisecond pulsars (MSPs) discovered as part of the L-band targeted survey of Fermi-LAT sources performed in the context of the Transients and Pulsars with MeerKAT (TRAPUM) Large Survey Project. Out of these pulsars, eight are members of binary systems; of these eight, two exhibit extended eclipses of the radio emission. Using an initial radio timing solution, pulsations were found in the gamma rays for six of the targets. For these sources, a joint timing analysis of radio times of arrival and gamma-ray photons was performed, using a newly developed code that optimises the parameters through a Markov chain Monte Carlo (MCMC) technique. This approach has allowed us to precisely measure both the short- and long-term timing parameters. This study includes a proper motion measurement for four pulsars, which a gamma ray-only analysis would not have been sensitive to, despite the 15-year span of Fermi data.

Published: October 2024

This study investigates the influence of circular cylinders positioned beside the advancing blade and in front of the returning blade on the performance of a Savonius wind turbine. The experimental method focuses on assessing how these cylinders affect the turbine’s efficiency and self-starting capability. Various distances between the cylinders and the turbine blades (S/D = 1.4) and different cylinder positions (Y/D = 1.27, 1.32, 1.37, 1.42, 1.51, 1.61, 1.71, 1.82, 2.00) were explored. Tests were conducted under constant speeds corresponding to Reynolds numbers of Re = 120,000 and 150,000. Preliminary findings of all various distances indicate a significant improvement in turbine performance, particularly in enhancing self-starting ability, when using these disturbance cylinders compared to conventional designs. Specifically, the configuration with cylinders positioned at S/D = 1.4 and Y/D = 1.51 demonstrated the most promising results, showing the static torque coefficient a 48% increase in performance at a wind speed of 6 m/s and a remarkable 78% increase at 7 m/s. These results highlight the potential of utilizing circular cylinders strategically around Savonius wind turbines to optimize their performance and operational efficiency.
The Effect of Changing the Nozzle Arrangement in the Vacuum Dryer on Decreasing the Moisture Content of Crude Palm Oil (CPO)
Authors: Prasetio Sandi , Dwiyantoro Bambang Arip
Published: October 2024

Crude palm oil is obtained from the mesocarp of oil palm fruit through a pressing process. The main cause of the decline in the quality of palm oil is the highwater content. Reducing humidity can be done by optimizing the palm oil dryer or what is called a vacuum dryer. The current vacuum dryers are considered less than optimal because the crude palm oil water content is often high, with the nozzles positioned in a straight line so that the distance between the nozzles is tight. For this reason, research was carried out on the effect of varying the diameter of the nozzle arrangement on reducing crude palm oil water content in vacuum dryers. The research was carried out at different nozzle distances in a vacuum dryer with varying nozzle arrangement diameters of 290 mm, 380 mm, 470 mm, 560 mm, and 650 mm and an inter-nozzle angle of 25.71° from the center of the vacuum dryer tube. This research starts from the design stage, making preliminary models, numerical studies, making prototypes, and experimental studies. From the research carried out on this vacuum dryer, the value of the amount of water vapor volume fraction formation in the vacuum dryer outlet channel for various nozzle arrangement variations was obtained. The total volume fraction of water vapor at a nozzle arrangement diameter of 290 mm is 3.31, a nozzle arrangement diameter of 380 mm is 3.64, a nozzle arrangement diameter of 470 mm is 0.68, a nozzle arrangement diameter of 560 mm is 4.37, and a nozzle arrangement diameter of 650 mm is 4.65. From these results it can be seen that the moisture content is proven to change in each nozzle arrangement and the most optimal decrease in moisture content occurs at a nozzle arrangement diameter of 650 mm as indicated by the formation of the largest volume fraction of water vapor. Based on experiments, it was found that the efficiency of the vacuum drying machine could reach 65.67%.

Published: October 2024

Drainage systems are crucial component of urban infrastructure, but development reduced infiltration areas and lowers drainage channel capacity due to sedimentation, rubbish and channel narrowing. Decreased drainage channel performance causes water to overflow the surface and cause inundation. This research introduces an innovative solution to enhance drainage channel performance by using porous concrete, which allows water to pass through its voids. This research aims to develop porous concrete by utilising granite and limestone waste. Waste granite and waste limestone have no selling value and can damage the environment. The research method uses experimental tests with variations in the mixture of waste as an added material. The mix variation is used to determine the optimal value of porous concrete permeability. Different variations of porous concrete mixtures: normal concrete, C1, C2, C3, C4. The results obtained found that concrete mix B4 with the largest variation of waste mixture. The speed of passing water with the comparison of normal concrete with C1, C2, C3 decreased. Normal concrete with C4 has an increase in speed of 10%. The findings of this study indicate that the larger the voids in the concrete, the greater the ability of water to escape. This paper provides a basis for further studies on flood mitigation in urban areas with reduced infiltration areas.

Due to their ability to be tailored in terms of strength, stiffness, and density, composite materials are a valuable commodity in the aerospace sector. But composite materials also deteriorate with time, just like other materials do, particularly in abrasive conditions like space. Thermal degradation brought on by abrupt temperature changes in the aircraft environment, which can result in dimensional changes, cracking, and even decomposition of composite materials, are degradation issues that can influence composite materials in aerospace applications. In this study, thermogravimetric analysis (TGA) of carbon/phenolic composites, as a fiber using carbon fiber (Kyoto carbon) with plain weave type and as a matrix using ARMC-551-RN phenolic resin. Furthermore, the test method refers to the ASTM E1131-08 Standard. Thermogravimetric Compositional Analysis Test Method. Ultimately, engineers hope to improve spacecraft design, reliability, and safety in severe space missions by using TGA analysis to understand the thermal characteristics and stability of carbon/phenolic composite materials utilized in spacecraft components.

Published: October 2024

Indonesia is a strategic maritime country, especially in terms of trade and economy. The most vital defense is Indonesian waters in the form of shipping by the Indonesian Navy. The support is in the form of nautical chart paper which is strong and waterproof. Natural paper reinforcement needs to be added because synthetic materials contain monomer groups, can damage the environment and are difficult to grade. Examples of natural agents are carrageenan and bentonite which work to form hydrogen bonds with cellulose fibers, thereby increasing the strength of paper. The research aims to study the effect of carrageenan and bentonite on opacity, tearing, tensile, wet index, and Cobb. The highest opacity was 100.2% in carrageenan with a dose of 14%. The highest tearing was in the mixed agent, amounting to 745.87 mN at a dose of 14%. The highest tensile dose of 14% was 1.58 kgf/15mm. The highest wet index dose is 14%, which is 2.55% of the mixed agent. The best Cobb for mixed agents with a dose of 14% was 67.09 g/m2. In conclusion, carrageenan and bentonite have potential as wet strength agents in making nautical chart paper.

Published: October 2024

Natural pigments are recommended to reduce the use of synthetic pigments, one of which is the primary color yellow. Carotenoids are natural yellow to red pigments that are produced naturally by plants and microorganisms. Fermentation of carotenoids by the microorganismNeurospora sitophilais one solution to the challenges of plant based pigment which compete with the needs of food, land, and dependence on weather and seasons. Corn cobs are one of the cellulotic wastes that can be used as a carbon source. This research aims to examine the effect of corn cob size (60, 20, 8 mesh) and fermentation time (3, 6, 9 days) on the carotenoid pigments produced. The spectrophotometer analysis show that fermentation increase the initial carotenoids concentration in corn cobs. The smaller the substrate and the longer fermentation time, the greater the concentration of carotenoids produced. The highest concentration was obtained on 60 mesh substrate with 9 days fermentation at 31.79 ppm. FTIR analysis shows the presence of carotenoid pigments by the C=C and C-H, and the O-H functional group which represent zeaxanthin, astaxanthin and neurosporaxanthin compounds. Based on SEM test results, the average particle size of corn cob powder was 50μm with porosity of 67.93%.

Fractures and ligament injuries often require bone fixation, commonly through Open Reduction and Internal Fixation (ORIF) with compression plates and screws. Additive manufacturing (AM) techniques are considered sustainable due to their potential to reduce emissions and have a minimal adverse impact on the environment. Currently, there is extensive research into producing biocomposite filaments, though there remains limited exploration of the impact of preheat temperature on filament properties. This research explores the effects of varying preheat temperatures in a single screw extruder to achieve biocomposite filament as candidate for biodegradable bone implants. Biocomposite filaments made from Polylactic Acid (PLA) and Polycaprolactone (PCL) in an 85:15 ratio, with 5% hydroxyapatite (HA) derived from green mussel shell waste. Biocomposite mixture was cut into sub-5mm fragments and extruded at 175°C with preheat temperatures between 159°C and 168°C. Filaments were used to fabricate specimens via a 3D printer, following ASTM D790 standards. Specimens were analyzed using X-Ray Diffractometer, Fourier Transform Infrared, Scanning Electron Microscope, density measurements, three-point bending tests, and biodegradation assessments. Results show that preheat temperature variations significantly affect the filament’s crystallinity index, impacting density and mechanical properties. Higher preheat temperatures result in a lower crystallinity index, decreasing density and potentially increasing degradation rates.
A Human-Centered Approach for Designing a Social Care Referral Platform
Authors: Haynes David , Cheng Pengxu , Weaver Megan , Parsons Helen , Karaca-Mandic Pinar
Published: October 2024

Background Health Information Technology is increasingly being used to help providers connect patients with community resources to meet health-related social needs (e.g., food, housing, transportation). Research is needed to design efficient, simple, and engaging interfaces during a sensitive process that involves multiple stakeholders. Research is also needed to understand the roles, expectations, barriers, and facilitators these different stakeholders (i.e., patients, providers, and community-based organizations [CBOs]) face during this process.

Objectives We applied the human-centered design approach to develop a multi-interface social care referral platform. This approach allowed us to understand the needs of each stakeholder and address potential workflow concerns.

Methods This paper reports on the research team's understanding of the design process from 48 different user tests. We conducted three rounds of user testing on an interactive prototype(s) and adapted the prototype after each round.

Results Our results summarize several key findings useful for patients, clinical teams, and staff of CBOs when designing a social care referral platform. Our user testing highlighted that patient-facing interfaces offer tremendous opportunities to allow patients to be the leader of the social care referral process. CBOs have varying needs that must be addressed, and providing CBO staff with opportunities to connect with patients is critical. Finally, health care teams have more structured workflows. Integration within the electronic health record system provides opportunities for health care staff to support their patients more easily given these barriers.

Conclusion Our resulting, patient-centered platform allows patients to self-screen and self-refer to organizations that match their unmet needs.
Bony Dorsal Preservation
Authors: Göksel Abdulkadir , Tran Khanh N. , Saadoun Rakan , Daniel Rollin K.
Published: October 2024

Rhinoplasty is undergoing a transformation with the reemergence of dorsal preservation rhinoplasty (DPR) techniques. This article introduces a novel addition to the DPR repertoire, “bony dorsal preservation” (BDP), which has particular application for the correction of crooked noses.

This comprehensive overview summarizes current DPR concepts and techniques, the intricate considerations that go into the dorsal osseocartilaginous vault and septal management, and how these are modified to treat the crooked nose. However, current DPR techniques, particularly the low septal strip (LSS), have drawbacks, and the desire to address such issues led to the development of BDP.

BDP is ideal for cases where there is no septal base pathology. It maintains the core principle of DPR by lowering dorsal humps without creating open roof deformities. Its unique feature is that it temporarily separates the upper lateral cartilages from the septum while leaving the septal base attachment intact, thus allowing the entire osseocartilaginous vault to be adjusted independently before reconnecting the preserved upper lateral cartilages. This technique offers direct visualization during septal excision and fixation and enables cartilaginous vault movement without sacrificing stability. Compared with LSS, there is more septal cartilage available for harvesting, the risks of a single point of septal fixation are eliminated, and there is the potential to transition to component reduction techniques, if needed. With shared indications and contraindications with other DPR methods, BDP emerges as a valuable addition to the evolving field of rhinoplasty, particularly in addressing the challenges of the crooked nose.
A Longitudinal Graduate Medical Education Curriculum in Clinical Informatics: Function, Structure, and Evaluation
Authors: Rowland Bradley , You Jacqueline , Stern Sarah , Bundy Richa , Moses Adam , Witek Lauren , Obermiller Corey , Rosenthal Gary , Dharod Ajay
Published: October 2024

Background There is a need to integrate informatics education into medical training programs given the rise in demand for health informaticians and the call on the Accreditation Council for Graduate Medical Education and the body of undergraduate medical education for implementation of informatics curricula.

Objectives This report outlines a 2-year longitudinal informatics curriculum now currently in its seventh year of implementation. This report is intended to inform U.S. Graduate Medical Education (GME) program leaders of the necessary requirements for implementation of a similar program at their institution.

Methods The curriculum aligns with the core content for the subspecialty of clinical informatics (CI) and is led by a multidisciplinary team with both informatics and clinical expertise. This educational pathway has a low direct cost and is a practical example of the academic learning health system (aLHS) in action. The pathway is housed within an internal medicine department at a large tertiary academic medical center.

Results The curriculum has yielded 13 graduates from both internal medicine (11, 85%) and pediatrics (2, 15%) whose projects have spanned acute and ambulatory care and multiple specialties. Projects have included clinical decision support tools, of which some will be leveraged as substrate in applications seeking extramural funding. Graduates have gone on to CI board certification and fellowship, as well as several other specialties, creating a distributed network of clinicians with specialized experience in applied CI.

Conclusion An informatics curriculum at the GME level may increase matriculation to CI fellowship and more broadly increase development of the CI workforce through building a cadre of physicians with health information technology expertise across specialties without formal CI board certification. We offer an example of a longitudinal pathway, which is rooted in aLHS principles. The pathway requires a dedicated multidisciplinary team and departmental and information technology leadership support.
Hemorrhaging Uterine Fibroid Leading to Emergent Early Term Cesarean Delivery: A Case Report
Authors: Racchi Nicholas , Bird Lisa , Mullan Samantha , Schnettler William , Billock Nanci
Published: October 2024

Background The incidence of uterine leiomyomas, or fibroids, affecting pregnant individuals is estimated to be 10%, but there are no guidelines or recommendations for fetal or maternal surveillance in pregnancies affected by them. Risks associated with fibroids during pregnancy include potential for pain, preterm birth, fetal growth restriction, higher cesarean delivery rate, fetal malpresentation, placenta abruption, and postpartum hemorrhage.

Case Presentation This case describes a 26-year-old gravida 1 para 0 who presented at early term for severe abdominal pain and was found to have acute abdomen accompanied by a nonreassuring fetal heart rate tracing. With emergent cesarean delivery, it was found that the patient was hemorrhaging from a ruptured vessel of a pedunculated fibroid and myomectomy was subsequently performed.

Conclusion While rare, hemorrhage from a uterine fibroid should be considered a part of the differential diagnosis of abdominal pain in pregnant patients with fibroids, particularly when accompanied by concurrent indicators such as free fluid, hypotension/tachycardia, or concerning changes in fetal heart rate, especially in a patient without risk factors for uterine rupture.
Investigating the Association between Preflap Negative-Pressure Wound Therapy and Surgical Outcomes in Extremity Free Flap Reconstruction: A Systematic Review
Authors: Rocks Madeline C. , Wu Meagan , Comunale Victoria , Agrawal Nikhil , Nicholas Rebecca S. , Azad Ali , Hacquebord Jacques H.
Published: October 2024

Background While prior studies have recommended immediate flap coverage within 72 hours of injury for soft tissue reconstruction for traumatic extremity injuries, recent evidence in the setting of advanced wound care techniques de-emphasizes the need for immediate coverage. Negative-pressure wound therapy (NPWT) has been an essential tool for extending the time to definitive soft tissue coverage. This study sought to elucidate the impact of preoperative NPWT use on the success of microsurgical reconstruction.

Methods A literature search was conducted using the following databases from their inception up to February 2023: PubMed, OVID databases (Embase and Cochrane Library), Web of Science, and Scopus. Of 801 identified articles, 648 were assessed and 24 were included. Cases were divided based on whether NPWT was used preoperatively or not. Timing to definitive coverage, injury details, and basic demographics were recorded. Rates of flap failure, infection, bone nonunion, reoperation, and complications were compared between groups.

Results A total of 1,027 patients and 1,047 flaps were included, of which 894 (85.39%) received preflap NPWT. The average time to definitive coverage for the NPWT and non-NPWT groups was 16 and 18 days, respectively. The NPWT group experienced lower postoperative complication rates than the non-NPWT group in all reported complications except for deep infections. Compared with the non-NPWT group, the NPWT group experienced lower rates of any flap failure (3.69 vs. 9.80%) and partial flap failure (2.24 vs. 6.54%).

Conclusion Preoperative NPWT was associated with reduced postoperative complications, most importantly flap failure rates. This merits further investigation into the decision-making process for traumatic extremity reconstruction. Future prospective studies adopting standardized protocols with longer follow-up are required to better understand the potentially beneficial role of preoperative NPWT use in soft tissue reconstruction.

Published: October 2024

Background Free fibular flaps have been suggested as a modality of reconstruction for complex spinal deformities. However, there is limited data that describes associated postoperative outcomes. The purpose of this systematic review was to characterize outcomes after spinal reconstruction using the free fibular flap for both adults and children.

Methods Thirty-nine articles among four databases were identified as having met inclusion criteria. Patient demographics, indications for spinal reconstruction as well as location and anastomosis, history of chemotherapy and radiation therapy, and postoperative outcomes including complications were identified. Major complications were defined as complications requiring reoperation, while minor complications were those that did not require reoperation. Systemic complications were defined as complications affecting sites or organ systems beyond the local donor and recipient sites. Statistical analysis was performed using Fischer's exact, chi-squared, and t-tests.

Results We identified 218 adult patients (mean age 47.7 years, 56.4% male) and 27 pediatric patients (mean age 12.7 years, 55.6% male). While there was no significant difference in the rates of bony union between the two groups (adults: 90.8%, children: 90%, p > 0.9), adults had significantly higher rates of major (27% vs. 7.4%, p = 0.026), minor (26.1% vs. 7.4%, p = 0.032), and systemic (14.2% vs. 0%, p = 0.047) complications.

Conclusion Free fibular flaps are effective for spinal reconstruction for both adults and children, as evidenced by the high rates of bony union. However, adults exhibited significantly higher complication rates. Further research is required to better understand the patient and clinical risk factors associated with increased rate of complications.

Published: October 2024

The JET-RANGER study (NCT03206762) was a multicenter (11 U.S. centers), randomized trial, core-lab adjudicated and designed to demonstrate the superiority of Jetstream + paclitaxel-coated balloon (JET + PCB) versus percutaneous transluminal angioplasty (PTA) + PCB in treating femoropopliteal arterial disease. The 1- and 2-year outcomes have been recently published. The 3-year outcome data are presented in this report. The JET-RANGER trial initially had 47 patients with 48 lesions. Thirty-one in the JET-PCB arm and 16 in the PTA + PCB arm (2:1 randomization). At 3-year follow-ups, there were 20 patients in the JET-PCB arm and 14 patients in the PTA + PCB arm. Kaplan–Meier survival analysis was performed to estimate the freedom from target lesion revascularization (TLR) at 3 years. Bailout stenting was not considered a TLR in this analysis. Statistical significance was determined by a p-value < 0.05. Freedom from TLR was statistically similar between the two groups at 3 years between JET + PCB and PTA + PCB (freedom from TLR was 88.0 vs. 67.8%, respectively, p = 0.1380). There was also no significant difference in the change of ankle-brachial index (ABI) between the PTA + PCB and JET + PCB from baseline at 6 months (p = 0.7890), 1 year (p = 0.4070), 2 years (p = 0.7410), and 3 years (p = 0.8010). There was also no statistical difference between the JET + PCB and PTA + PCB arms for RCC improvement by one or more categories from baseline to 3 years (p = 0.8949). There were no minor or major amputations for either arm throughout the 3-year follow-up. Five JET + PCB patients died before the 3-year specified window and none in the PTA + PCB arm (p = 0.137). Two of the deaths were due to cancer and three due to cardiac causes. None were deemed related to the device or procedure. JET + PCB had similar freedom from TLR and improvement in ABI and RCC at 3-year follow-up with no difference in amputation or mortality between the 2 arms. A trend toward less TLR was seen in the JET + PCB arm.
Flexibly Incorporating the Dyad into Psychosocial Intervention: Considerations for Neuropalliative Care
Authors: Plys Evan , Szapary Claire L. , Vranceanu Ana-Maria
Published: October 2024

This paper reviews dyadic psychosocial intervention approaches that flexibly incorporate both dyad members despite challenges to equitable involvement due to cognitive limitations or limited availability. We provide an overview, analysis, and examples for the following dyadic intervention approaches: (1) shared interventions that involve each dyad member equitably (i.e., higher care recipient cognition, higher care-partner availability); (2) patient-focused interventions that primarily engage care recipients with early stages of neurocognitive disorders, yet include care-partners in select sessions and target dyadic and relationship needs (i.e., higher care recipient cognition, lower care-partner availability); and (3) care-partner focused interventions that primarily engage care-partners, yet still address care recipient and relationship needs (i.e., lower care recipient cognition, higher care-partner availability). In our review, we propose a flexible definition of dyadic psychosocial intervention that considers the continuum of individuals' involvement, measurement, content, and conceptual background. We conclude with a discussion of implications for neuropalliative care.
A Case Report: Regenerative Biodegradable Chin Implant—A Viable Futuristic Option
Authors: Bhave Medha , Jaiswal Yogesh Rameshchandra
Published: October 2024

Chin augmentation can dramatically transform a patient's appearance. Various techniques are in use, each with their specific problems and limitations. We present the first case report from the Indian subcontinent using a custom 3D-printed, bioresorbable polycaprolactone implant. We demonstrate, by appropriate imaging, the replacement of the implant at long-term (22 months) follow-up by patient's own autologous bone formation. An excellent aesthetic result was achieved. Relevant points of technique, as well as pertinent properties of the material, are discussed. This material has been used in neurosurgery and in the management of orbital fractures. Yet, worldwide, very few (3–4) cases of chin implant have been done using this material. We believe this to be a useful and sustainable material, offering several advantages, as set out in the case report.
The effectiveness of ChatGPT as a lexical tool for English, compared with a bilingual dictionary and a monolingual learner’s dictionary
Authors: Lew Robert , Ptasznik Bartosz , Wolfer Sascha
Published: October 2024

Traditionally, language learners have relied on dictionaries when trying to read or write in a foreign language. However, new LLM-based chatbots may offer an alternative to traditional dictionaries as lexical tools. This study assesses the effectiveness of ChatGPT versus the monolingual Longman Dictionary of Contemporary English (LDOCE, 2024) and the bilingual Diki.pl (Diki.pl, 2024) online dictionaries in supporting English language learners in receptive and productive lexical tasks. With a sample of 166 university students at B2 to C1 proficiency levels and forty uncommon English phrasal verbs, we investigate whether a leading AI-driven chatbot, a high-quality learners’ dictionary, or a popular free bilingual dictionary offers better support in accurately understanding and producing English. The results reveal ChatGPT to be more effective than either dictionary in production, and better than the monolingual dictionary, but not the bilingual dictionary, in reception.

Authors: Jain Kanishk , Tak Mukesh , Mote Rakesh G.
Published: October 2024

Used extensively in the aerospace industry, the superalloy Inconel 718 is deemed hard to cut because of its rapid work hardening, low thermal conductivity, and excessive shear strength. Proposed here is patterning Inconel 718 with micro-dimples using electrochemical machining and electrical discharge machining prior to conventional cutting. How this micro-dimple patterning influences the machinability of Inconel 718 is analyzed via orthogonal cutting experiments, and with the optimal parameters, the cutting temperature is lowered by 45.5% and the cutting forces are reduced significantly, i.e., the tangential cutting force and the thrust force are reduced by 61.1% and 47.1%, respectively. The predictions of finite-element simulations agree with experimental observations, and it is concluded that dimpled Inconel 718 offers significantly improved tool wear and surface integrity.

ZIF-8 is widely applied in lubrication, adsorption, and catalysis owing to its unique physicochemical properties. Previous experimental studies have demonstrated its feasibility as a lubricant additive. In the present work, the lubricating performance of ZIF-8 as an additive to lithium-based grease is quantitatively and dynamically analyzed at the atomic scale using molecular dynamics simulations. Friction wear experiments are also conducted to elucidate the lubrication mechanism of ZIF-8. The simulation and experimental results indicate that the incorporation of ZIF-8 effectively enhances the antifriction and antiwear characteristics of lithium grease. The most significant improvement in the lubrication performance of the grease is obtained at a mass fraction of 2.0 wt. % ZIF-8, which reduces the friction factor μ of the grease by about 17.0% and the wear by ∼40.0%. Furthermore, the molecular dynamics simulations reveal that ZIF-8 primarily functions as a ball bearing under low-load conditions. However, under high-load conditions, ZIF-8 undergoes significant deformation and primarily acts as a filler. This explains the experimentally observed significant reduction in friction coefficient after the addition of ZIF-8. The results of this study provide a theoretical foundation for the development of new environmentally friendly grease additives.

Published: October 2024

Autoregressive models (ARMs) can be powerful tools for quantifying uncertainty in the time averages of turbulent flow quantities. This is because ARMs are efficient estimators of the autocorrelation function (ACF) of statistically stationary turbulence processes. In this study, we demonstrate a method for order selection of ARMs that uses the integral timescale of turbulence. A crucial insight into the operating principles of the ARM in terms of the time span covered by the product of model order and spacing between samples is provided, which enables us to develop computationally efficient implementations of ARM-based uncertainty estimators. This approach facilitates the quantification of uncertainty in downsampled time series and on a series of autocorrelated batch means with minimal loss of accuracy. Furthermore, a method for estimating uncertainties in second-order moments using first-order uncertainties is discussed. These techniques are applied to the time series data of turbulent flow a) through a plane channel and b) over periodic hills. Additionally, we illustrate the potential of ARMs in generating synthetic turbulence time series. Our study presents autoregressive models as intuitive and powerful tools for turbulent flows, paving the way for further applications in the field.

A coplanar-volume coupled discharge utilizing a capillary coplanar dielectric barrier discharge (CDBD) as a pre-ionization source and employing a negative direct current (DC) voltage to prompt plasma propagation from the dielectric surface to the air gap is proposed and experimentally investigated. Optical-electrical properties, spatial-temporal evolution of plasma, and active species generation are systematically studied to provide in-depth insights into the plasma characteristics of coplanar-volume coupled discharge based on pre-ionization. Compared to traditional dielectric barrier discharge, this approach reduces the inception voltage and significantly enhances the discharge intensity. Spatial-temporal evolution of plasma morphology demonstrates two distinct discharge processes occurring in coplanar-volume coupled discharge: coupled primary discharge and coupled secondary discharge. These processes are developed from the coplanar primary discharge and coplanar secondary discharge in capillary CDBD, respectively. Through analyzing the effects of pulse voltage and negative DC voltage on the physical and chemical properties of plasma, coplanar-volume coupled discharge based on high pre-ionization exhibits strong plasma luminous intensity, elevated discharge energy, and heightened chemical activity.

Published: October 2024

A light guide is an essential part of many scintillator counters and light collection systems. Our main interest is a light guide for a thin, wide scintillator that has high light transmission while converting the area of the light source to the shape of a photo-detector. We propose a variation of the light guide that avoids a 90° twist of the strips, reduces the length of the light pipe, and reduces the complexity of production. Detailed Monte Carlo simulation studies have been performed for a three-strip S-shaped light-guide system.

Published: October 2024

While memcapacitors exhibit scalability, a sneak-path-free nature, and lower power consumption compared to memristors, the sensitivity and responsiveness of conventional memcapacitors are lower than expected due to their physical mechanisms. Quantum capacitance, which is controlled by the Fermi level and the density of states, holds the potential to enhance memcapacitor performance and address these issues. In this study, a unique memcapacitor based on the MoS2 quantum capacitance (MoS2 quantum memcapacitor, MQM) is proposed, and the “learning-forgetting” behavior of simulated synapses is discussed. Initially, the quantum capacitance memory effect of MoS2 was demonstrated. Subsequently, under gate voltage (Vg) control, the MQM exhibited a sensitive response and excellent repeatability. Finally, the MQM demonstrated a range of artificial synaptic behaviors consistent with biological synapses, including transformations from short-term potentiation to long-term potentiation and from short-term depression to long-term depression, as well as high pair-pulse-facilitation behavior. This showcases its excellent versatility and flexibility, thereby promoting the development of an integrated artificial neural network.

Published: October 2024

The electrical control of magnetic anisotropy in spintronic devices holds significant promise for various applications but remains challenging. Here, based on first-principles calculations, we demonstrate nonvolatile electrical control of magnetic anisotropy by constructing a van der Waals multiferroic structure comprising a ferromagnetic LaBr2 monolayer (ML) and a ferroelectric In2Se3 ML. By utilizing the electric polarization of the In2Se3 ML, the LaBr2 ML, which exhibits properties of a two-dimensional XY ferromagnet, can transition into an Ising ferromagnet, resulting in a switch in the easy magnetization axis (EMA) from in-plane to out-of-plane directions. Additionally, the LaBr2 ML undergoes a phase transition from a semiconductor to a metallic state, offering potential for logic devices. These remarkable changes in EMA and electronic properties stem from polarization field-induced band bending at the interface and interfacial charge transfer. Our findings not only pave the way for achieving nonvolatile electrical control of magnetic anisotropy in a ferromagnetic LaBr2 ML on a ferroelectric In2Se3 substrate but also provide insight for designing nonvolatile memory and logic devices.
A novel binary data classification algorithm based on the modified reaction–diffusion predator–prey system with Holling-II function
Authors: Chen Jialin , Chen Xinlei , Wang Jian
Published: October 2024

In this study, we propose a modified reaction–diffusion prey–predator model with a Holling-II function for binary data classification. In the model, we use u and v to represent the densities of prey and predators, respectively. We modify the original equation by substituting the term v with f−v to obtain a stable and clear nonlinear decision surface. By employing a finite difference method for numerical solution of the original model, we conduct various experiments in two-dimensional and three-dimensional spaces to validate the feasibility of the classifier. Additionally, with consideration for wide real applications, we perform classification experiments on electroencephalogram signals, demonstrating the effectiveness and robustness of the classifier in binary data classification.
Distinctive features of the relationship between the structure and conductive properties of polycrystal Na3Fe2(PO4)3, obtained by the melt-quenching method of nanoarchitectronics

In this work, the features of the structure-conductivity relationship in polar (α) and ion-conducting (β and γ) phases of Na3Fe2(PO4)3 polycrystals obtained by the melt-quenching method have been investigated. Na3Fe2(PO4)3 polycrystals are synthesized by isothermal firing of glassy precursors (after grinding and pressing). The glassy precursors were prepared by melting a pre-calcined (350 C) mixture of initial reagents under the influence of thermal and infrared radiation energy and rapid cooling of the melt (or quenching). It was found that the deformations of the structure of polycrystals α-Na3Fe2(PO4)3 during synthesis by melt-quenching lead to an increase in the conductivity in polar (α) and ion-conducting (β and γ) phases because they contribute to the reduction of structural distortions of the samples. Polycrystals Na3Fe2(PO4)3 obtained by the melt-hardening method have high-quality crystallites, high density, and conductivity, and their synthesis is faster than samples obtained by other methods. The established advantages of synthesized polycrystals of α-Na3Fe2(PO4)3 are probably connected with deformations of structure and chemical activity of glassy precursors caused by nonequilibrium thermodynamic conditions of synthesis. For the first time, it was possible to detect domain structures in polycrystals of α-Na3Fe2(PO4)3 obtained by the melt-quenching method, which confirms the polarity of the α-phase, the appearance of which is associated with the ordered displacement of the cationic sublattice relative to the anionic sublattice under the influence of monoclinic distortion of the crystal framework.

Published: October 2024

The Atomic, Molecular, and Optical Science (AMOS) Gateway is a comprehensive cyberinfrastructure for research and educational activities in computational AMO science. The B-Spline atomic R-Matrix (BSR) suite of programs is one of several computer programs currently available on the gateway. It is an excellent example of the gateway’s potential to increase the scientific productivity of AMOS users. While the suite is available to be used in batch mode, its complexity does not make it well-suited to the approach taken in the gateway’s default setup. The complexity originates from the need to execute many different computations and to construct generally complex workflows, requiring numerous input files that must be used in a specific sequence. The BSR graphical user interface described in this paper was developed to considerably simplify employing the BSR codes on the gateway, making BSR available to a large group of researchers and students interested in AMO science.
