Proboscis lateralis- A 17 years follow-up, a case report
Authors: Vyas Udyan H. , Raibagkar Santosh C. , Vora Himanshu J. , Bhavsar Dhaval 
Published: March 2024

ABSTRACTProboscis lateralis is a rare congenital anomaly for which no embryological basis has been established. Besides heminasal aplasia or hypoplasia, various other craniofacial anomalies are also associated with it. It is only uncommonly free of other anomalies. Evaluation of a patient should include CT scan examination to look for growth of facial and skull bones. Reconstruction should start at an early age. Proboscis itself is the best option for heminose formation. Cartilaginous or bony support can be planned later in the late teens to give good aesthetic result.

Facilitating Healing in Diabetic Foot Ulcers Using Homeopathy in a Multi-Disciplinary Integrative Approach: Two Evidence-Based Case Reports
Authors: Ponnam Hima Bindu 
Published: March 2024

Abstract
Background A rising incidence of diabetic foot ulcers (DFUs) in India has escalated the rate of lower limb amputations in the country. The present study aims to evaluate the potential healing properties of homeopathic medicines as a part of the integrative management of DFUs through two evidence-based case reports.
Methods Two patients with DFUs, identified as Wagner grade 2, having had diabetes for 12 years, were treated with individualized homeopathic medicine within a multi-disciplinary approach. Both cases were on oral hypoglycemic agents for managing blood sugar, continued their diabetic medication, and were advised to use regular wound dressings. The DFUs were assessed using the Pressure Ulcer Scale for Healing (PUSH) score at baseline and every 4 weeks until complete wound healing. Neuropathic changes were evaluated by the 10g monofilament tactile test, and the Modified Naranjo Criteria for Homeopathy—Causal Attribution Inventory (MONARCH) tool was used to assess the likelihood of there being a causal relationship between clinical improvement and the homeopathic intervention.
Results The DFUs showed healing within 12 weeks, with a significant improvement in the PUSH score, though there was no change in tactile sensation as assessed by the monofilament test. The MONARCH tool yielded +9 in both cases, indicating the likelihood of a causal relationship between the clinical outcome and homeopathic intervention. The homeopathic medicines Arsenicum album and Lachesis respectively were found useful by each patient.
Conclusion Homeopathy appeared beneficial in facilitating the early healing of DFUs within a multi-disciplinary integrative approach.

Published: March 2024

AbstractThe internet has introduced many resources frequently accessed by patients prior to orthopaedic visits. Recently, Chat Generative Pre-Trained Transformer, an artificial intelligence-based chat application, has become publicly and freely available. The interface uses deep learning technology to mimic human interaction and provide convincing answers to questions posed by users. With its rapidly expanding usership, it is reasonable to assume that patients will soon use this technology for preoperative education. Therefore, we sought to determine the accuracy of answers to frequently asked questions (FAQs) pertaining to total knee arthroplasty (TKA).Ten FAQs were posed to the chatbot during a single online interaction with no follow-up questions or repetition. All 10 FAQs were analyzed for accuracy using an evidence-based approach. Answers were then rated as “excellent response not requiring clarification,” “satisfactory requiring minimal clarification,” satisfactory requiring moderate clarification,” or “unsatisfactory requiring substantial clarification.”Of the 10 answers given by the chatbot, none received an “unsatisfactory” rating with the majority either requiring minimal (5) or moderate (4) clarification. While many answers required nuanced clarification, overall, answers tended to be unbiased and evidence-based, even when presented with controversial subjects.The chatbot does an excellent job of providing basic, evidence-based answers to patient FAQs prior to TKA. These data were presented in a manner that will be easily comprehendible by most patients and may serve as a useful clinical adjunct in the future.
Energy loss analyses of amorphous magnetic ribbons by multi-frequency single sheet tester
Authors: Pfützner Helmut , Shilyashki Georgi , Bengtsson Claes 
Published: March 2024

Due to low values of both thickness and conductivity, Fe-based amorphous soft magnetic ribbon (AR) is an attractive alternative to crystalline silicon steel (CS) for elevated frequencies f up to several kHz. On the other hand, for corresponding tests of losses P, the only standardized method is restricted to just 400 Hz. Recently, we reported “Physically Consistent Loss Testing” (CLT) for loss tests of CS for f up to 10 kHz. Here, we describe an adaptation of a corresponding multi-frequency single sheet tester for AR-applications. The CS single sheet is replaced by six 50 cm long and 17 cm wide ARs, loosely inserted into a paper envelope. This “envelope technique” provides (i) simple sample arrangement in an absolutely flat state, (ii) high repeatability, (iii) robust sensor signals, (iv) avoidance of loss increases due to magneto-mechanical effects, and (v) averaging over thickness variations of ARs through as much as 100 g of sample mass. Here, we report the results of frequency analyses for sinusoidal magnetization in the longitudinal direction for induction up to 1.5 T for f &lt; 1 kHz and 0.4 T for 10 kHz, with P up to 50 W/kg. Anisotropy tests confirm a very weak dominance of the transverse direction. In conclusion, CLT proves to be an effective tool for loss tests on both CS and AR as a physically consistent principle. Therefore, for the ongoing standardization of SST with H-coil, we recommend considering the integration of the “envelope technique” in order to establish rapid and universal multi-frequency loss testing.

The optical floating zone crystal growth technique is a well-established method for obtaining large, high-purity single crystals. While the floating zone method has been constantly evolving for over six decades, the development of high-pressure (up to 1000 bar) growth systems has only recently been realized via the combination of laser-based heating sources with an all-metal chamber. While our inaugural high-pressure laser floating zone furnace design demonstrated the successful growth of new volatile and metastable phases, the furnace design faces several limitations with imaging quality, heating profile control, and chamber cooling power. Here, we present a second-generation design of the high-pressure laser floating zone furnace, “Laser Optical Kristallmacher II” (LOKII), and demonstrate that this redesign facilitates new advances in crystal growth by highlighting several exemplar materials: α-Fe2O3, β-Ga2O3, and La2CuO4+δ. Notably, for La2CuO4+δ, we demonstrate the feasibility and long-term stability of traveling solvent floating zone growth under a record pressure of 700 bar.
Realization of a composite ferroelectric characterization test system using a modified constant current method and a modified virtual ground method
Authors: Wang Ding-Yeong 
Published: March 2024

A composite ferroelectric characterization test system constructed using a modified constant current method (CCM) and a modified virtual ground method (VGM) has been successfully designed and implemented. By sending instructions to the microcontroller through software, the system’s test mode can be easily changed by arranging the switching status of six switching elements. When validating the system, a dual-channel precision source/measure unit B2912B was used to verify this design. There is also parasitic capacitance that cannot be ignored in this commercial machine. This parasitic capacitance affects the appearance of the entire hysteresis curve. However, the parasitic capacitance values also differ in various test current ranges. In addition, to confirm the data credibility of this composite ferroelectric test system, Keysight B1530A and Radiant Premier II were used to conduct cross-verification between different systems. The results obtained between different systems show good consistency. Furthermore, reproducible and recoverable imprint phenomena were found in this composite system during interactive validation using VGM and CCM methods. After designing different voltage profiles for verification, it was found that the root cause of this imprint phenomenon was the difference between the final polarization state of the previous test and the pre-initialized polarization state. This imprint phenomenon exists in traditional Pb(Zr, Ti)O3 (PZT) ferroelectric capacitors and Hf0.5Zr0.5O2-based ferroelectric capacitors. Fortunately, this imprint phenomenon is reversible. Moreover, this imprint phenomenon disappears through the design of the time-varying voltage profile on the ferroelectric capacitor of the CCM method.
ReaxFF molecular dynamics simulations of methane clathrate combustion
Authors: Bai Dongsheng , Zhang Jie 
Published: March 2024

Understanding the ignition and dynamic processes for the combustion of hydrate is crucial for efficient energy utilization. Through reactive force field molecular dynamics simulations, we studied the high-temperature decomposition and combustion processes of methane hydrates in a pure oxygen environment. We found that at an ignition temperature of 2800 K, hydrates decomposed from the interface to the interior, but the layer-by-layer manner was no longer strictly satisfied. At the beginning of combustion, water molecules reacted first to generate OH•, followed by methane oxidation. The combustion pathway of methane is CH4→CH3•→CH3O•→CH2O→HC•O→HCOO•→CO(CO2). During the combustion process, a liquid water layer was formed between melted methane and oxygen, which hindered the reaction’s progress. When there is no heat resistance, oxygen will transform into radicals such as OH• and O•, which have faster diffusion rates, allowing oxygen to conveniently cross the mass transfer barrier of the liquid water layer and participate in the combustion process. Increasing the amount of OH• may cause a surge in the reaction. On the other hand, when significant heat resistance exists, OH• is difficult to react with low-temperature hydrate components, but it can transform into O• to trigger the oxidation of methane. The H• generated has a sufficient lifetime to contact high-temperature oxygen molecules, converting oxygen into radicals that easily cross the water layer to achieve mass transfer. Therefore, finding ways to convert oxygen into various radicals is the key to solving the incomplete combustion of hydrates. Finally, the reaction pathways and microscopic reaction mechanisms of each species are proposed.
Impact of Co2C nanoparticles on enhancing the critical current density of Bi-2223 superconductor

Published: March 2024

We have investigated the superconducting properties of nanocomposite pellets made from Bi-2223 and Co2C powders. Our measurements reveal loss of superconducting fraction in the nanocomposites. However, the retained superconducting fraction exhibits robust bulk superconducting properties. The Tc of the retained superconducting fraction was 109 K, which was found to be comparable to that of the pure Bi-2223 pellet. We found that the composite’s net magnetization response is a superposition of the contributions of ferromagnetic and superconducting fractions. Analysis revealed that the surviving superconducting fraction exhibits a robust Meissner response. In the nanocomposite, the irreversibility field of the superconducting fraction at 77 K is found to increase by almost three times compared to the pristine material, thereby showing strong vortex pinning features. We also find a broadened magnetic field regime over which we observe that a single vortex pinning regime sustained in the nanocomposite. The critical current density, Jc, of the nanocomposite was found to be approximately five times higher than that of the pristine Bi-2223 pellet at low T. In fact, the enhancement in Jc is most significant in the high T regime, where at temperatures close to Tc in the nanocomposite, we see almost two orders of magnitude increase in Jc compared to the pristine Bi-2223 pellet. Our study suggests that larger sized agglomeration of magnetic nanoparticles of Co2C leads to loss of superconductivity in the nanocomposite. However, there are also unagglomerated Co2C nanoparticles distributed uniformly throughout the nanocomposite, which act as efficient pinning centers that allow for collective vortex pinning centers to be retained, even up to temperatures near Tc, and these nanoparticles also do not compromise the bulk Tc of the superconducting fraction. Our study shows that these nanocomposites that exhibit enhanced Jc especially in the high T regime are potentially useful for high current applications.

Published: March 2024

Single-photon time-of-flight (TOF) non-line-of-sight (NLOS) imaging enables the high-resolution reconstruction of objects outside the field of view. The compactness of TOF NLOS imaging systems, entailing the miniaturization of key components within such systems, is crucial for practical applications. Here, we present a miniaturized four-channel time-correlated single-photon counting module dedicated to TOF NLOS imaging applications. The module achieves excellent performance with a 10 ps bin size and 27.4 ps minimum root-mean-square time resolution. We present the results of the TOF NLOS imaging experiment using an InGaAs/InP single-photon detector and the time-correlated single-photon counting module and show that a 6.3 cm lateral resolution and 2.3 cm depth resolution can be achieved under the conditions of 5 m imaging distance and 1 ms pixel dwell time.

Published: March 2024

Objective It is widely understood that a key means of improving health systems and patient outcomes is through research – accessing, understanding, generating and applying research evidence-based practice. To promote more targeted and strategic research in Allied Health practice, this study sought to establish the principles, areas and priorities for clinical research as perceived by Allied Health leaders in the South Australian public health system. Methods The study used a mixed-methods design (full, sequential and equal model). Participants were recruited from the South Australian Department of Health and Wellbeing employment lists for Allied Health senior leaders. Consenting participants attended face-to-face focus groups; after an overview presentation, they discussed the principles for Allied Health research, followed by areas and priorities for research. Summaries of the responses were themed descriptively and circulated electronically so participants could confirm the research areas and ascribe priority ratings, clinical populations and services. Results A total of 28 people attended the stakeholder forum (5 online); 20 responded to the second-round electronic summary. Nine principles of research action were agreed. Fourteen research areas were identified and prioritised. There was a relatively consistent prioritisation of measuring Allied Health value, Allied Health workforce, hospital avoidance and closing the gap for Aboriginal and Torres Strait Islander peoples health outcomes – whether the individuals were thinking about their own service or the state as a whole. Conclusions Allied Health leadership identified key principles and priorities for research to improve service delivery and patient outcomes. These priorities should generate further discussion and interest for novice and experienced researchers and leaders and can be used to inform granting and project plans.

Published: March 2024

Abstract
Nowadays, timekeeping is an essential component in modern computing. The Network Time Protocol (NTP) is a distributed service based on a hierarchical network protocol used to synchronize computer clocks over a network in an easy and scalable manner. Currently, this protocol is the main mechanism used on the internet to provide a common notion of time to all computers. The Real Instituto y Observatorio de la Armada (ROA) realizes Spanish legal time and disseminates it via the internet from two publicly accessible NTP time servers. In this study, it is assessed the implementation and characterization of two NTP time servers over a Local Area Network in client-to-server and server-to-server modes from the side of NTP protocol and all its functionalities. These measurements aim to analyze the client-to-server mode operation, forcing the polling interval at different values, and to verify the consistency of the results by employing the ppstest tool to compare one pulse‐per‐second from the UTC (ROA) with the client time offset. This comparison corroborates the proper operation of the NTP time server configured as stratum 1 and referred directly to UTC (ROA), and shows how a real deployment can be professionally deployed with the aim of distributing time over a public service using NTP.
