Analytical approach to piezoelectric model synthesis with the use of Cauer’s method for system design
Authors: Harazin Jacek , Wróbel Andrzej
Published: September 2024

Background Piezoceramic materials have unique property which enables direct and bilateral conversion between mechanical and electrical energy. This ability facilitates significant miniaturisation of technology and opens many opportunities in design of new actuators and energy harvesters. Mathematical modelling of piezoelectric modules is notoriously hard due to complex constitutive equations defining mechanical and electrical energy conversion. Methods The article presents research on a new synthesis method based on the Cauer’s method. Mechanical damping is introduced with the use of Rayleigh’s approximation. A discrete electromechanical model is formed based on the Mason’s piezoelectric model. The proposed approach allows modelling of piezoelectric systems based on a set of characteristic frequencies. The method allows a more general approach to the problem of modelling new systems, as opposed to application-oriented methods seen in literature. A non-standard model analysis method using edge graphs and structural numbers is also verified as a potential alternative for matrix-based method. The authors compare their precision and computation requirements. Results The structural method of mechanical model analysis gave identical results as the reference matrix method. However, the non-classical algorithm took much longer to calculate and was using more memory. The electromechanical model analysis has shown an error of 5% in comparison to resonance frequencies taken from a reference plate specification. The calculated magnitude of displacement was well above the capability of a 3.5mm thick piezoelectric plate. Conclusions The synthesis method presented in this paper allows synthesizing piezoelectric cascade models based on limited information in form of characteristic frequencies. Currently this method allows a coarse approximation of the real piezoelectric parameters with limited number of inputs. The additional method of analysis based on structural numbers offers a promising alternative to matrix calculations but requires a more thorough investigation of the computational power required to determine whether it can compete with existing algorithms.

Authors: Asriadi Asriadi , Yetti Krisna , Novieastari Enie , Gayatri Dewi
Published: September 2024

Background Education for diabetes patients is not managed well by diabetes nurse educators because the competency of diabetes nurse educators is low, and the number of diabetes nurse educators in hospitals is not commensurate with the number of diabetes patients, which is much larger. Methods This qualitative phenomenological research uses an exploratory design. Twenty nurse managers and forty staff nurses who participated in the focus group discussion (FGD) were selected using purposive sampling. Nine staff nurses who participated in in-depth interviews were selected using the snowball method. The results of the FGD exploration and in-depth interviews produced components for developing an educational model with a management approach. The development of this educational model uses an input, process, output, and outcome approach. The input uses King’s conceptual framework approach, the method uses the theory of goal attainment and management functions, the output is the competency of nurses to educate diabetes patients, and the outcome is the health literacy of diabetes patients. This educational model was reviewed by three experts: a nursing management expert, a diabetes mellitus expert, and a health literacy expert. Results The educational model for Diabetes nurse educators with a management approach consists of five stages: 1) Educational planning includes identifying educational targets, strategy formulation, and situation analysis. 2) Organizing nursing resources includes strengthening the role of nurses as diabetes educators. 3) Nursing staff includes intraprofessional collaboration and collaboration between nurses and patient families. 4) Direction includes nurses’ motivation for diabetes patients and respecting the culture and values of diabetes patients. 5) Control includes evaluating nurse education for diabetes patients. Conclusion This education model has five competencies, which are structured and systematic so that diabetes nurse educators have the competence to manage diabetes patient education: the personal system, interpersonal system, and social system influence nurse competency.

Background Muscarinic receptor agonism is a promising mechanism of action for treating psychosis, not present in most D2R-blocking antipsychotics. Xanomeline, an M1/M4-preferring agonist, has shown efficacy in late-stage clinical trials, with more compounds being investigated. Therefore, we aim to synthesize evidence on the preclinical efficacy of muscarinic receptor agonists in animal models of psychosis to provide unique insights and evidence-based information to guide drug development. Methods We plan a systematic review and meta-analysis of in vivo animal studies comparing muscarinic receptor agonists or positive allosteric modulators with control conditions and existing D2R-blocking antipsychotics in animals subjected to any method that induces behavioural changes of relevance for psychosis. We will identify eligible studies by searching multiple electronic databases. At least two independent reviewers will conduct the study selection and data extraction using prespecified forms and assess the risk of bias with the SYRCLE’s tool. Our primary outcomes include locomotor activity and prepulse inhibition measured with standardized mean differences. We will examine other behavioural readouts of relevance for psychosis as secondary outcomes, such as social interaction and cognitive function. We will synthesize the data using multi-level meta-analysis with a predefined random-effects structure, considering the non-independence of the data. In meta-regressions we will explore potential sources of heterogeneity from a predefined list of characteristics of the animal population, model, and intervention. We will assess the confidence in the evidence considering a self-developed instrument thatconsiders the internal and external validity of the evidence.

Pride or Guilt? Impacts of Consumers’ Socially Influenced Recycling Behaviors on Closed-Loop Supply Chains
Authors: Huang Wenjie , Nguyen Jason , Tseng Chung-Li , Chen Wenlin , Kirshner Samuel N.
Published: September 2024

Problem definition: Social influenced emotions of pride and guilt have been identified by the environmental psychology (EP) literature as crucial drivers impacting recycling behavior, but they have mostly been overlooked in operations management (OM) research. In contrast, EP studies often ignore firms’ operational decisions. We analyze the impacts of both social influence and firms’ operational decisions to provide a comprehensive understanding of consumers’ recycling behaviors, which is essential for realizing remanufacturing’s full potential. Methodology/results: We consider a closed-loop supply chain consisting of a manufacturer selling a single product to a consumer community. Consumers’ recycling behavior depends on both the recycling reward offered by the manufacturer, as well as intrinsic and socially influenced pride (guilt) from recycling (not recycling). We develop an evolutionary game to model consumers’ recycling behavior and characterize the resulting equilibrium recycling rate, which is then integrated into the manufacturer’s decision problem. We characterize the manufacturer’s optimal strategy and the equilibrium recycling rate in four distinct regions defined by both the product’s overall difficulty of remanufacturing and the underlying strengths of consumers’ socially influenced pride and guilt. We show that in settings where the product has a moderately high difficulty of remanufacturing and consumers have stronger socially influenced pride than guilt, the manufacturer optimally induces an interior recycling rate. In such scenarios, there exist win-win pathways in using social influence–based interventions to increase both the manufacturer’s profit and the recycling rate. However, misalignment may occur when consumers substantially care for the product’s recyclability. Managerial implications: This study bridges sustainable OM and EP literature by analyzing how consumers’ socially influenced emotions of pride and guilt affect a manufacturer’s optimal decisions, profits, and the resulting recycling rate. We provide important insights for designing effective and efficient social influence–based interventions to improve recycling rates.

Published: September 2024

Highlights

Used one- and two-point normalization to compensate for drifts in EC and pH probes in hydroponic systems.

Developed automated sensor drift compensation systems for hydroponic systems.

Evaluated the compensation systems for open- and closed-hydroponics.

Application of the normalization methods increased the accuracy of the EC and pH measurements.

Abstract. In hydroponic systems, the nutrient solutions are dispensed based on pH and electrical conductivity (EC) to ensure that the nutrient components in the solution are optimal for crop growth. However, the pH and EC probes may exhibit signal drifts when immersed in the solution for a considerable period, which deteriorate the measurement accuracy and the nutrient and water use efficiency. Notably, the existing hydroponic systems require manual calibration of the pH and EC probes and do not provide any information regarding their accuracy. Consequently, faults in the probes are challenging to detect. In this study, two types of automated drift compensation systems for EC and pH probes, based on one- and two-point normalization, were developed to accurately monitor changes in the pH and EC values in hydroponic solutions and enhance sensor management. The proposed framework can provide information regarding the drifts of the pH and EC probes through automated normalization solution measurements. The effectiveness of the developed system in scenarios involving plant growth with open and closed hydroponics was evaluated through comparison with a standard method involving sampling and laboratory analysis. The results indicated that the one-point normalization strategy had a simple structure and was effective in compensating drifted offsets of sensors. A two-point normalization strategy could effectively predict the sensor drifts as well as variations in the sensitivities, which could be used in the compensation processes. Application of the one-point normalization-based system increased the accuracy of the EC and pH measurements, with root mean square errors decreasing from 50 to 28.5 µS·cm-1 and 0.43 to 0.17 pH in the open hydroponic systems and from 68.7 to 38.3 µS·cm-1 and 0.15 to 0.11 pH in the closed systems, respectively. The two-point normalization-based system decreased the RMSEs from 44.6 to 33.4 µS·cm-1 and 0.55 to 0.20 pH for the EC and pH measurements, respectively. In addition, the decreased slope and coefficient of determination in the linear regression according to the system application proved the system can compensate for the drifts of the EC and pH probes. The proposed system provided accurate EC and pH measurements and sensor status information, promoting more efficient nutrient use and sensor maintenance. Keywords: Automation, Compensation, Drift, EC, Hydroponics, pH.

Introduction: Heterotopic ossification of the Achilles tendon (HOTA) is a rare but consequential complication to an inflammatory event, often presenting challenges in diagnosis and management. Case Report: We report a case of a 42-year-old male with Type II diabetes mellitus, managed with Metformin, who presented with acute pain and swelling in the right ankle following a running activity. Clinical examination revealed tenderness and a visible swelling proximal to the calcaneum attachment of the tendon which was hard in consistency, and a positive Thompson test indicative of a potential Achilles tendon injury. Imaging, including X-ray and magnetic resonance imaging, confirmed a complete avulsion tear with cranial retraction of the torn tendon and heterotopic ossification seen proximal to the torn end of the tendon. Surgical intervention, employing a posterior paramedian approach under tourniquet control, involved tendon approximation using the Speed bridge technique, incision over the proximal tendon and removal of the ossified tendon, and repair of the incised tendon sheath. Postoperatively, the patient received a tailored medication regimen and was advised strict non-weight-bearing measures, wound management, and limb elevation. The patient was discharged in a stable condition. Conclusion: This case underscores the importance of early recognition and prompt surgical intervention in managing HOTA, particularly in patients with underlying risk factors. The presented surgical approach and postoperative management contribute to the evolving strategies for addressing this rare clinically significant condition. Keywords: Heterotopic ossification, diabetes mellitus, surgical intervention, speed bridge technique.

Introduction: Hydatid diseases are a parasitic infestation of human and herbivorous animals caused by a cestode, Echinococcus granulosus. The liver and lung are commonly involved organs and the involvement of muscles and bones is very unusual, even in the countries where echinococcal infestation is endemic. Case Report: We report a case of muscular hydatidosis of the hand and forearm in a 71-year-old male without particular histories, who consulted for tumefaction of the right hand and forearm evolving for 2 years. Biology and the standard radiographs were without anomalies. The diagnosis was evoked on magnetic resonance imaging (MRI) and confirmed by surgical biopsy and excision. The operative follow-up was simple with no recurrence after 3 years. Conclusion: Muscular echinococcosis is an extremely rare disease. An MRI evaluation should be taken into account as the gold standard in the diagnosis. Surgical cystectomy is often indicated, and an excision with wide margins is mandatory to avoid the rupture of the cyst and anaphylaxis. Adjuvant pharmacological therapy is recommended to minimize the risk of recurrence. Keywords: Hydatidosis, cyst, muscle, hand, forearm, excision.

Introduction: Giant cell tumor of bone (GCTB) is a rare yet locally aggressive neoplasm primarily affecting young adults. Its hallmark features include multinucleated osteoclast-type giant cells and mononuclear tumor cells. Treatment with denosumab, an anti-RANK ligand antibody, has shown efficacy, but it alters histomorphology, posing diagnostic challenges. Co-occurrence with achondroplasia, though rare, warrants consideration in bone lesion evaluations. Case Report: A 30-year-old male with achondroplasia presented with a proximal femur GCT, a rare association. Neoadjuvant denosumab was administered due to thin tumor cortex and cortical breech. Surgical excision with bone cement filling and Philo’s plate supplementation was performed. Histopathological examination post-treatment revealed the absence of osteoclast-type giant cells, extensive necrosis, hyalinization, and mononuclear infiltrates. Discussion: Denosumab induces a reduction in osteoclast numbers, causing tumor shrinkage and sclerosis, while altering typical GCT histology. Similar findings were noted in the literature, including stromal changes like spindle-shaped cells, inflammation, vascular proliferation, and hemosiderin-laden foamy macrophages. Recognition of these alterations is crucial for accurate diagnosis. Conclusion: GCT, though rare, presents distinct histopathological features aiding diagnosis. Denosumab treatment modifies tumor morphology, necessitating thorough clinical evaluation for accurate diagnosis post-treatment. Understanding, these challenges is essential for optimal management of GCT cases. Keywords: Giant cell tumor, achondroplasia, denosumab therapy, challenges in histopathology.

Introduction: Fibrous dysplasia (FD) is a skeletal developmental abnormality commonly affecting the ribs, femur, tibia, skull, pelvis, spine, and shoulder. FD of the proximal radius is extremely rare and very few cases have been reported. In addition, monostotic lesions of FD in the upper extremity go unnoticed as they are usually asymptomatic. Symptomatic lesions warrant surgical intervention. Here, we present a rare case of FD of the proximal radius treated with curettage and non-vascularized fibular cortical strut graft with intramedullary elastic nailing. We believe that this is the first report in the literature wherein this treatment modality has been undertaken. Case Report: A 27-year-old woman presented with excruciating pain and swelling in her right elbow for 4 weeks, with no inciting event or trauma leading to the pain. Plain radiographs revealed a well-circumscribed radiolucent lesion in the proximal radius with cortical thinning at the metaphysis and a rim of epiphyseal bone. Clinically, the patient had restricted supination (50°) and limited elbow range of motion (ROM) (20–130°), mostly because of the pain but had full pronation. With these radiographic and clinical features, FD and giant cell tumor were kept as differential diagnoses and surgical treatment was planned. The lesion was excised leaving the normal epiphysis of the radius intact and samples were sent for histopathological examination. A non-vascularized fibular cortical strut graft was harvested from the same side and was fluted into the radial shaft. Final stabilization was done using a 2.5 mm intramedullary elastic nail. The arm was immobilized in an above-elbow slab. Histopathology confirmed our diagnosis of FD. The slab was removed after 6 weeks, and a gentle ROM was started in the form of active-assisted ROM. At the end of 1 year, complete union and almost full ROM were achieved and the patient was completely pain-free. Conclusion: Non-vascularized fibular strut grafting with intramedullary nailing provides a comparatively quicker, cost-effective way of treating this lesion with a minimum insult of the bony cortex and quicker rehabilitation. Keywords: Fibrous dysplasia, proximal radius, strut graft, intramedullary nailing.
Transforming Banking with Artificial Intelligence
Authors: Mucsková Monika
Published: September 2024

Purpose of the article: The purpose of this article is to provide a comprehensive analysis of the role of artificial intelligence (AI) in the banking sector, focusing on its applications, challenges, and implications. By synthesizing existing research and empirical studies, the article aims to inform researchers about the transformative potential and inherent challenges of AI-driven innovation in banking.
Methodology/methods: Using a systematic review approach, the relevant literature on AI integration in banking was identified from electronic databases and leading corporate research departments, ensuring a synthesis of scholarly and industry perspectives.
Scientific aim: With limited academic research on AI in banking, this study aims to shed light on its applications, challenges, and implications.
Findings: The integration of AI in the banking sector has significantly transformed various operational areas, including customer interactions, risk management, compliance, and operational efficiency. AI applications, such as chatbots and smart virtual assistants, have enhanced customer service by offering personalized, 24/7 support, and have demonstrated significant cost and revenue benefits. AI-driven credit scoring and fraud detection have improved risk assessment and mitigation, enabling more precise and informed decision-making. However, AI adoption faces challenges such as high computational costs, data quality issues, the "curse of recursion" where models trained on AI-generated data degrade, and the need to balance trust in AI outputs with their reliability. Furthermore, regulatory considerations play a crucial role in AI integration. While the European Union's AI Act aims to ensure the ethical use of AI in finance, it also presents challenges related to compliance and potential over-regulation.
Conclusions: In conclusion, the integration of AI in the banking sector has revolutionized customer service, risk management, compliance, and operational efficiency. However, the adoption of AI also raises concerns about data privacy, security, and the need for regulatory frameworks to ensure ethical use. As AI continues to evolve, it will be crucial for banks to balance technological innovation with responsible practices to maximize benefits and mitigate risks.
Farianas’ insurgent feminism: for a militant, affective and embodied reincorporation in Colombia
Authors: Anctil Avoine Priscyll
Published: September 2024

In 2016, by moving from armed struggle to collective reincorporation, Colombian women ex-guerrilleras of the Revolutionary Armed Forces of Colombia – People’s Army (FARC-EP) – the farianas – reconfigured the ‘combatant’ identity by leaving their weapons and engaging in post-war politics with their own feminist vision: insurgent feminism. Drawing upon feminist ethnographic fieldwork conducted in the north-east of Colombia in 2019 and 2022, this article has two interlinked objectives. First, through the lenses of embodiment and affects, it explores the challenges and contradictions of transiting from an armed organisation to a civilian identity for women militants. From there, the article then uses the continuum of militancy to explore the (ongoing) consolidation of farianas’ insurgent feminism and the tensions emerging in this endeavour. In doing so, the article contributes, theoretically, to the inclusion of emotions and embodiment in the theorisation of reincorporation and, empirically and politically, to the construction of knowledge and practice about insurgent feminism.
‘Is this a joke?’ Exploring how care experienced people feel their way through inheritance and what their emotions ‘do’
Authors: Edwards Delyth , Canning Rosie
Published: September 2024

Inheritance provokes mixed emotions and feelings for people who engage in this ‘family practice’ (Monk, 2014; 2016). Inheritance can be a way of ‘doing’ and ‘displaying ‘family’ but can also be a way of un/making families (Edwards and Canning, 2023). The aim of this article is to explore how care experienced people ‘feel their way through’ (Ahmed, 2014) inheritance. We do this by triangulating findings from informal empirical research we undertook on social media with an analysis of the broader literature on inheritance contained within blogs, autobiographies and museum exhibitions about care experience. We make two key arguments. The first is that inheritance can be attributed as a source of feeling for care experienced people. We consider how our question on social media immediately sparked negative ‘emotional expressions’ (Bericat 2016), related to feelings of exclusion, loss and anger of inheritance not being of relevance to them. The quote in our article title – ‘Is this a joke?’ – was an expression from a person who responded to our research. Second, we argue that while marginalised and absent within orthodox inheritance practices, care experienced people are ‘feeling subjects’ (Bericat, 2016), who derive new forms and ways of creating and (re)imagining inheritance from the emotions associated with being ‘othered’ by inheritance practices. Drawing on Sara Ahmed’s (2014: 4) question: ‘What do emotions do?’, we show that care experienced people ‘feel their way through’ and ‘do’ different things with the emotions they attribute to inheritance to forge new inheritances.
The USSR and the Uprising of 1956 in Hungary
Authors: Kokebayeva Gulzhaukhar
Published: September 2024

Abstract: The Hungarian protest was a harbinger of events in Eastern Europe: in 1968 in Czechoslovakia, in 1980–81 in Poland, and in the late 1980s in other countries of the region. After World War II these states, as well as Hungary, experienced the construction of the Soviet model of socialism. The first attempts to adapt socialism to local conditions were suppressed by the USSR, resulting in an outbreak of popular protest. Soviet researchers assessed the events of 1956 in Hungary as a counterrevolutionary uprising fueled by internal reactionary forces with the support of aggressive imperialistic powers. The goal of these powers was perceived to be the weakening and forced retreat of socialist forces, and hence the introduction of a rift within the ranks of socialist states. After the collapse of the socialist system in the late 1980s, the archives opened their doors and researchers gained access to the Soviets' deep scientific analytical work on the Hungarian popular uprising. The authors of the present article attempt to show the degree of Soviet interference in the internal affairs of Hungary in the 1950s, which was one of the reasons for the revolution.

Space-time reconstruction for lensless imaging using implicit neural representations
Authors: Chien Tiffany , Cao Ruiming , Liu Fanglin Linda , Kabuli Leyla A. , Waller Laura
Published: September 2024

Many computational imaging inverse problems are challenged by noise, model mismatch, and other imperfections that decrease reconstruction quality. For data taken sequentially in time, instead of reconstructing each frame independently, space-time algorithms simultaneously reconstruct multiple frames, thereby taking advantage of temporal redundancy through space-time priors. This helps with denoising and provides improved reconstruction quality, but often requires significant computational and memory resources. Designing effective but flexible temporal priors is also challenging. Here, we propose using an implicit neural representation to model dynamics and act as a computationally tractable and flexible space-time prior. We demonstrate this approach on video captured with a lensless imager, DiffuserCam, and show improved reconstruction results and robustness to noise compared to frame-by-frame methods.
Bridging the resolution-sectioning gap in STED nanoscopy with coherent-hybrid depletion
Authors: Belsley Michael , Soares-de-Oliveira Joana , Pereira António J.
Published: September 2024

Microscopes generally achieve better 2D imaging compared to 3D, and super-resolution microscopes often aggravate such axial-lateral resolution mismatch. A prime example is vortex phase-based stimulated emission depletion (STED) fluorescence microscopy, which only narrows the point-spread function laterally, thereby increasing the point-spread function (PSF) anisotropy. In this study, we developed a semi-analytical theory based on the Nijboer-Zernike expansion, developed a set of metrics and performed experiments to establish the merits of the alternative, bivortex phase-based, coherent-hybrid STED. We find that this mode reduces the axial-lateral resolution mismatch by providing access to PSF geometries that are strictly forbidden to the two conventional single-beam modes, emulating noisier multi-beam approaches. Both theory and experiment indicate that bivortex STED not only addresses the axial-lateral resolution gap but also delivers a higher signal-to-background ratio than the two more common STED modes that it bridges.
Optomechanical entanglement manipulation and switching in a squeezed-cavity-assisted optomechanical system

Published: September 2024

Quantum entanglement is pivotal in modern quantum technologies, spanning applications from quantum networks to quantum metrology. Controllable quantum entanglement in cavity optomechanical systems has been an enduring pursuit. We propose a unique method for flexible manipulation and switching of optomechanical entanglement in a squeezed-cavity-assisted optomechanical system consisting of a χ(2)-nonlinear optical cavity and an optomechanical cavity. Squeezing the nonlinear optical cavity through parametric pumping allows effective control of light-light and light-vibration interactions within the system. This capability of the squeezed system plays a key role in manipulating quantum entanglement. We find that quantum entanglement between the unsqueezed cavity mode and the mechanical mode can be effectively regulated by adjusting the pump laser parameters. Furthermore, by turning the phase of the pump, we can achieve highly flexible quantum switching between entanglement and separability. Additionally, we demonstrate increased entanglement between the squeezed cavity mode and the mechanical mode when completely suppressing the pump-induced optical input noise. Our findings pave the way not only towards the manipulation and protection of fragile quantum entanglement but also to achieve photon-phonon quantum control by exploiting quantum squeezing.

An inline-delay Fourier transform imaging spectrometer (iFTIS) is used to measure spatiospectral coupling in a mid-infrared (mid-IR) optical parametric amplifier (OPA). The method employs a compact inline delay line using a birefringent wedge pair and a microbolometer array as an imaging sensor, providing continuous spectral coverage from ∼0.4 to 4.5 µm in a single device. We find a spatial chirp that depends systematically on the OPA wavelength setting in the 3-4 µm range and also identify spatiospectral couplings beyond spatial chirp, highlighting the importance of advanced metrological techniques for this spectral region. Furthermore, we investigate the effect of depletion on the 2 µm pump beam and observe a complex spatiospectral reshaping. Our work opens the door to new applications of iFTIS to mid-IR laser science.

Laser-induced breakdown spectroscopy (LIBS) is a highly promising technique for the in-situ, real-time diagnosis of impurity deposits on the inner walls of tokamak devices. The deposited impurity on plasma-facing materials (PFCs) pose a significant risk to the steady-state operation of the tokamak. Under vacuum conditions, an accurate quantitative analysis of the thin co-deposition layers is a technical challenge. In this study, 30 co-deposited layer samples of tungsten (10.0–92.3 a.t.%), molybdenum (2.0–77.8 a.t.%), iron (2.9–12.1 a.t.%) and copper (1.2–18.7 a.t.%) were prepared to simulate the co-deposition layers found on PFCs in Experimental Advanced Superconducting Tokamak (EAST). A variation of the CF-LIBS algorithm, the so-called One Point Calibrated LIBS (OPC-LIBS), was employed to analyze these co-deposited layer samples under conditions of 5 × 10−5 mbar. It was found that the matrix matching degree among the measured samples and the selection of standard samples play a decisive role in the quantitative analysis capability of OPC-LIBS. In actual situations, the composition of the co-deposited impurity layers at different locations in the Tokamak will be quite different. We addressed this challenge by developing the Classified OPC-LIBS (COPC-LIBS) model, an enhanced version of OPC-LIBS with pre-classification to offset matrix effects in LIBS analysis. For tungsten in the co-deposition layers, the root mean square (RMSE) calculated by the CF-LIBS method was 14.7, the OPC-LIBS method was 11.5, and the newly invented COPC-LIBS was reduced to only 5.1. The COPC-LIBS method is a highly efficient technique that can precisely measure the distribution of co-deposited layers on the surface of inner wall materials. The diagnostic data obtained from this method will provide valuable insights into the interaction between plasma and wall materials during the operation of fusion devices.
General theory of a moving Fabry-Perot Interferometer
Authors: Duan Lingze
Published: September 2024

This paper seeks to establish a general framework that describes the transmission and reflection properties of a Fabry-Perot interferometer when key components in its operation system, including the light source, the detector and the interferometer itself, have relative motions against each other along their common optical axis. Our analysis indicates that these movements result in new factors in the transmission and reflection coefficients, which are generally caused by the Doppler effect. As a demonstration of its potential application, the new theory is applied to the Pound-Drever-Hall frequency-locking technique. It is shown that velocity-induced frequency modulations are effectively added to the laser frequency due to the motions, and such excess frequency noise can be impactful in certain applications.

The 2 μm wavelength band emerges as a promising candidate for the next communication window to enhance the transmission capacity of data. A high-responsivity and high-speed photodetector operating at 2 μm is crucial for the 2-μm-wavelength-band communication system. Here, we present an on-chip waveguide-coupled germanium photodetector with remarkably high responsivity and data-receiving rate, employing subbandgap light absorption and avalanche multiplication. The device is designed with an ingenious and simple asymmetric lateral p-i-n junction structure and fabricated through a standard CMOS process by a commercial factory. It has a responsivity of 3.64 A/W and a maximum bandwidth of 50 GHz at 2 μm wavelength. For the first time, to the best of our knowledge, an optical receiving rate of up to 112 Gbps is demonstrated at 2 μm, verifying its feasibility in a high-speed 2-μm-band communication system. To the best of our knowledge, the proposed device stands out as the fastest photodiode with the highest responsivity among all group III-V and group IV photodetectors working in the 2 μm wavelength band.

The high-power quantum cascade laser (QCL) frequency comb capable of room temperature operation is of great interest to high-precision measurement and low-noise molecular spectroscopy. While a significant amount of research is devoted to the longwave spectral range, shortwave 3–5 μm QCL combs are still relatively underdeveloped due to the excessive material dispersion. In this work, we propose a monolithic integrated multimode waveguide scheme for effective dispersion engineering and high-power-efficiency operation. Over watt-level output power at room temperature with a wall plug efficiency of 7% and robust dispersion reduction is achieved from a quantum cascade laser frequency comb at a wavelength approximately 4.6  μm. Narrow beatnote linewidth less than 1 kHz and clear dual-comb multiheterodyne comb lines manifest the coherent phase relation among the comb modes which is crucial to fast molecular spectroscopy. This monolithic dispersion engineered waveguide design is also compatible to an efficient active–passive optical coupling scheme and would open up a new research playground for ring comb and on-chip dual-comb spectroscopy.

The trans-spectral manipulation of spatio-temporal structured light, characterized by dynamic inhomogeneous trajectories and a unique nature in the space–time domain, opens myriad possibilities for high-dimensional optical communication in the ultraviolet band. Here, we experimentally demonstrate the high-performance transfer of the spatio-temporal optical Ferris wheel beam from near-infrared to blue–violet wavelengths. Owing to the energy conservation and momentum conservation mechanism, the 420 nm output signal beam accurately retains the spatio-temporal characteristics of the 776 nm input probe optical Ferris wheel beam, facilitated by the 780 nm Gaussian pump beam. The identical multi-petal intensity profiles confirm the successful transfer of spatial characteristics from the input probe to the output signal beams. The fully synchronized rotation velocities and directions of the probe and signal beams demonstrate the precise transfer of temporal characteristics, achieving approximately 98% conversion accuracy. This work enables efficient information transfer across different wavelength bands and offers a promising approach for achieving high-dimensional quantum communication.

Person-centered care (PCC) is foundational to improve client’s experiences in care while advancing HIV-related outcomes. However, information is scarce on how to assess PCC in HIV treatment settings. This study team developed the PCC assessment tool (PCC-AT) to assess the performance in HIV clinics in Ghana. The objectives of this study were to: (1) pilot the PCC-AT and assess scoring consistency and reliability among clients and providers; and (2) assess content validity of the PCC-AT through client key informant perspectives and experiences. An analysis of similarities and differences in PCC-AT domain scores between ART providers and clients was conducted to assess score reliability. Axial and open coding of transcripts using NVivo identified key themes. Findings indicate that the PCC framework aligns with client’s priorities, additionally two out of the three PCC domain scores demonstrated consistency between ART providers and clients. Emerging differences in ART provider and client perspectives highlighted opportunities for growth and underscored the importance of continually gathering client feedback as an integral component of a PCC assessment to continually strengthen ART services.
