Published: October 2022

UV-C irradiation critically effects the growth of micro-fungi and also deteriorate leather materials. In the present study vegetable tanned and chrome tanned leather were infected with pure cultures of Aspergillus niger and Aspergillus flavus, which were isolated from stored leather materials. UV-C light (λ = 254 nm) was applied on infected leather for 15 and 60 min. The changes in leather qualities were examined through weight, tensile strength, scanning electron microscope, energy dispersive X-ray and Fourier transform infrared spectroscopy study after 15 and 30 days of fungal inoculation. Vegetable tanned leather was more vulnerable in case of fungal attack than chrome tanned leather while A. flavus showed more influence on leather deterioration than A. niger. The results showed that weight loss after 30 days for 15 and 60 min irradiation exposure was 1.3% compared to A. flavus infected leather (3.93%). The tensile strength of vegetable and chrome tanned UV irradiated leather was increased by 44% and 7% respectively. The scanning electron microscopic images exhibit the limited presence of conidiophores in UV-C exposed leather which confirmed the potentiality of irradiation for controlling fungal growth. The infrared spectral analysis of UV-C exposed infected leather samples showed neither shifting of wavenumber nor displacement of any functional groups. Altogether the efficacy of UV-C irradiation against biodeterioration of leather was concluded to be effective. This method can be used to control fungal growth without compromising the leather quality.

Critical care ultrasonography (US) is widely used by intensivists managing critically ill patients to accurately and rapidly assess different clinical scenarios, which include pneumothorax, pleural effusion, pulmonary edema, hydronephrosis, hemoperitoneum, and deep vein thrombosis. Basic and advanced critical care ultrasonographic skills are routinely used to supplement physical examination of critically ill patients, to determine the etiology of critical illness and to guide subsequent therapy. European guidelines now recommend the use of US for a number of practical procedures commonly performed in critical care. Full training and competence acquisition are essential before significant therapeutic decisions are made based on the US assessment. However, there are no universally accepted learning pathways and methodological standards for the acquisition of these skills.

Therefore, in this review, we aim to provide a methodological approach of the head to toe ultrasonographic evaluation of critically ill patients considering different districts and clinical applications.

Published: October 2022

The magnetotelluric (MT) data collected in an ore-concentration area are extremely vulnerable to all kinds of noise pollution. However, separating real MT signals from strong noise is still a difficult problem, and the noise in MT data is quite distinct from clean data in morphological features. By performing the signal-noise identification and data prediction, we develop a deep learning method to denoise MT data containing strong noise. First, we use the convolutional neural network (CNN) to learn the feature differences between the samples of massive noise and clean data and use the learned features to realize signal-noise identification of the measured data. Second, we use the measured clean data obtained by CNN identification to train the long short-term memory (LSTM) neural network and perform the prediction denoising of the noisy data. The simulation results clearly demonstrate the following two facts: (1) the predicted data output from LSTM basically matches the time-frequency domain features of the real data and (2) our CNN method performs significantly better than the features parameter classification method in dealing with signal-noise identification. In addition, the validity of our method is verified by the processing results of the measured data.
Residual learning with feedback for strong random noise attenuation in seismic data
Authors: Liao Zhangquan , Li Yong , Liu Yingtian , Yang Yifan , Zhang Yiming
Published: October 2022

In random seismic noise attenuation, when the noise energy is higher than or close to a signal, it is difficult to distinguish the signal from the noise. This random noise is relatively strong compared to the signal and is called strong random noise. We have developed a deep learning framework to recover the signal from the strong random noise. The framework is based on a residual learning network and feedback connection and is called the feedback residual network. The residual network (ResNet) suppresses random noise through residual fitting and improves the network’s training efficiency. The feedback connection allows the framework to process data in iterations. In each iteration, the feedback connection proportionally combines the input and output of the ResNet to reconstruct a new input with a lower noise level. This enhances denoising performance by asymptotically decreasing the input noise level and retrieving the remaining signals from the estimated noise, thereby reducing the difficulty of strong random noise attenuation. We terminate the feedback iterations according to the energy change of the estimated noise in each iteration. Synthetic and field examples demonstrate that our network can effectively attenuate the strong random noise.
Implications of static low-frequency model on seismic geomechanics inversion
Authors: Sharifi Javad
Published: October 2022

I have developed a novel insight into the differences between static and dynamic moduli and their effects on the performance of seismic geomechanics inversion. This achievement is obtained from triaxial deformation tests and ultrasonic measurements on core plugs and reveals that the static Young’s modulus deviates from the dynamic one in porous media, especially in particular ranges of depth and pressure, although conventional regression relationships suggest the opposite, i.e., similar trends for the static and dynamic Young’s moduli. Next, a novel simple approach is formulated to incorporate laboratory information directly into a seismic low-frequency model (LFM) using an artificial neural network to achieve a static low-frequency model (SLFM). Respecting the critical role of the LFM in the reliability of seismic inversion, any modification to the process of building this model can contribute to higher accuracy of the subsequent seismic geomechanics modeling. For this, LFMs are built using static and dynamic data before proceeding to seismic inversion to derive 3D cubes of static Young’s and bulk moduli. The results are successfully validated using data from known wells as well as a blind well. The modeling outcomes demonstrate that the seismic inversion based on the dynamic low-frequency model (DLFM) would return the same results for static and dynamic bulk moduli. In contrast, the results are erroneous for the static Young’s modulus when the conventional DLFM was adopted. Accordingly, the intelligent approach to static low-frequency modeling is found to be a good interpolation technique for estimating geomechanical parameters, as indicated by the good agreement between the static data and the corresponding inversion results at the well locations. My findings place emphasis on the necessity of reconsidering the relationship between the static and dynamic Young’s moduli and highlight the advantage of using an SLFM to increase the accuracy of geomechanical modeling.
Channel connection and stimulated reservoir volume estimation derived by the timing, location, and focal mechanism of microseismic events
Authors: Liu Lei , Song WeiQi , Yang XiaoHui , Zhou DeShan , Dong Lin , Hu JianLin
Published: October 2022

Understanding and modeling channels of high-pressure liquids during hydraulic fracturing and stimulated reservoir volume (SRV) estimation are critical for the evaluation of the fracturing effect and the prediction of oil and gas production in unconventional (low permeability and porosity) reservoirs. In this study, we developed a “focal mechanism-to-event” channel connection criterion based on the timing, location, and focal mechanism of microseismic events, enabling the channel to be perpendicular or parallel to the fracturing plane and more in line with the mechanical properties of rock rupture. We first evaluated the two endpoints of all channels as a set of spatial points, followed by the application of the alpha-shape method to detect the concave hull shape boundary formed by the spatial points. Finally, we calculated the SRV by combining the shapes of the concave hull and Delaunay triangulation. In the experimental simulation, we found that this method could effectively calculate the hull volume, and the detected concave hull included all microseismic events and channels. Ultimately, we applied the channel connection criterion and SRV estimation method to a stage of 3.18 h real fracturing data containing 216 microseismic events. The final calculation revealed a total of 410 connection channels and 4.3154 × 105 m3 SRV, which is more consistent with the expected than the “event-to-event” or “event-to-channel” connection criteria and bin or convex hull SRV calculation methods.
The mental health associations of vitiligo: UK population-based cohort study
Authors: Thompson Andrew R. , Eleftheriadou Viktoria , Nesnas John
Published: October 2022

Background

Vitiligo is an acquired, autoimmune depigmenting skin disorder that may affect psychological well-being.

Aims

To determine the risk and impact of psychological comorbidity in people with new-onset vitiligo.

Method

We conducted a retrospective observational study, using UK general practice data (2004–2020). Adults diagnosed with vitiligo (n = 7224) were matched 1:4 with controls (n = 28 880). Associations within 2 years of diagnosis were assessed for psychological conditions: recurrent depressive disorder (RDD), depressive episodes, non-phobia-related anxiety disorder, social phobia, adjustment disorder, substance misuse, self-harm and suicide attempts. Healthcare utilisation, time off work and unemployment within 1 year were compared in those with and without a mental health condition at vitiligo diagnosis.

Results

At diagnosis, people with vitiligo had a similar prevalence of mental health conditions as controls, except for anxiety disorder (cases 7.9%, controls 7.0%; P = 0.014). Incident RDD and anxiety disorder were more common in people with vitiligo (RDD: adjusted hazard ratio (aHR) 1.25, 95% CI 1.01–1.55; anxiety disorder: aHR 1.23, 95% CI 1.00–1.51). Risk was highest in Black and minority ethnic individuals (RDD: aHR 1.72, 95% CI 1.06–2.79; depressive episodes: aHR 1.56, 95% CI 1.03–2.37). No association was found with other mental health conditions. People with vitiligo and psychological comorbidity had more primary care encounters, more time off workand higher unemployment.

Conclusions

People with vitiligo have a higher incidence of RDD and anxiety disorder than controls, and this risk increase may be greatest in Black and minority ethnic populations.

Published: October 2022

Background

While shared clinical decision-making (SDM) is the preferred approach to decision-making in mental health care, its implementation in everyday clinical practice is still insufficient. The European Psychiatric Association undertook a study aiming to gather data on the clinical decision-making style preferences of psychiatrists working in Europe.

Methods

We conducted a cross-sectional online survey involving a sample of 751 psychiatrists and psychiatry specialist trainees from 38 European countries in 2021, using the Clinical Decision-Making Style – Staff questionnaire and a set of questions regarding clinicians’ expertise, training, and practice.

Results

SDM was the preferred decision-making style across all European regions ([central and eastern Europe, CEE], northern and western Europe [NWE], and southern Europe [SE]), with an average of 73% of clinical decisions being rated as SDM. However, we found significant differences in non-SDM decision-making styles: participants working in NWE countries more often prefer shared and active decision-making styles rather than passive styles when compared to other European regions, especially to the CEE. Additionally, psychiatry specialist trainees (compared to psychiatrists), those working mainly with outpatients (compared to those working mainly with inpatients) and those working in community mental health services/public services (compared to mixed and private settings) have a significantly lower preference for passive decision-making style.

Conclusions

The preferences for SDM styles among European psychiatrists are generally similar. However, the identified differences in the preferences for non-SDM styles across the regions call for more dialogue and educational efforts to harmonize practice across Europe.
A Novel Bootstrapping Test for Analytical Biosimilarity
Authors: Zahel Thomas
Published: October 2022

Showing analytical similarity is key to license biosimilar products with reduced or circumvented clinical effort. Statistical procedures to assess analytical similarity of quality attributes at drug product level have been highly debated by academia, industry, and regulatory agencies. In the past, a tiered approach was recommended by regulators, consisting of equivalence tests and quality range tests. However, this approach has recently been withdrawn by FDA. New guidelines of FDA and EMA favour the usage of quality range tests. Moreover, it has recently been shown that simple range tests, such as the 3SD test, are flawed, since they do not control the agency risk of falsely declaring a non-biosimilar product as being biosimilar (Type I error). This has also been highlighted by regulators recently. In this contribution, we developed a novel bootstrapping test for assessing analytical similarity that overcomes current flaws of equivalence and range tests. The developed test shows the desired properties, that is, (i) similarity conditions can be easily defined, (ii) differences of mean and the variance between the biosimilar and the innovator can be studied simultaneously, and (iii) the Type I error of the test can be controlled at a low level, e.g. 5%, evenly along the entire similarity condition. Moreover, the test shows up to 10% higher mean power values in the similarity region compared to existing range tests that aim to control the Type I error. Hence, this test is superior to existing quality range tests and is perceived compliant with current regulatory requirements.

Published: October 2022

Context

Isolated hypogonadotropic hypogonadism (IHH) is phenotypically and genetically heterogeneous.

Objective

This work aimed to determine the correlation between genotypic severity with pubertal and neuroendocrine phenotypes in IHH men.

Methods

A retrospective study was conducted (1980-2020) examining olfaction (Kallmann syndrome [KS] vs normosmic IHH [nHH]), baseline testicular volume (absent vs partial puberty), neuroendocrine profiling (pulsatile vs apulsatile luteinizing hormone [LH] secretion), and genetic variants in 62 IHH-associated genes through exome sequencing (ES).

Results

In total, 242 men (KS: n = 131 [54%], nHH: n = 111 [46%]) were included. Men with absent puberty had significantly lower gonadotropin levels (P < .001) and were more likely to have undetectable LH (P < .001). Logistic regression showed partial puberty as a statistically significant predictor of pulsatile LH secretion (R2 = 0.71, P < .001, OR: 10.8; 95% CI, 3.6-38.6). Serum LH of 2.10 IU/L had a 95% true positive rate for predicting LH pulsatility. Genetic analyses in 204 of 242 IHH men with ES data available revealed 36 of 204 (18%) men carried protein-truncating variants (PTVs) in 12 IHH genes. Men with absent puberty and apulsatile LH were enriched for oligogenic PTVs (P < .001), with variants in ANOS1 being the predominant PTV in this genotype-phenotype association. Men with absent puberty were enriched for ANOS1 PTVs compared to partial puberty counterparts (P = .002). PTVs in other IHH genes imparted more variable reproductive phenotypic severity.

Conclusion

Partial puberty and LH greater than or equal to 2.10 IU/L are proxies for pulsatile LH secretion. ANOS1 PTVs confer severe reproductive phenotypes. Variable phenotypic severity in the face of severe genetic variants in other IHH genes point to significant neuroendocrine plasticity of the HPG axis in IHH men.
Biological and Therapeutic Implications of the Tumor Microenvironment in Pituitary Adenomas
Authors: Ilie Mirela-Diana , Vasiljevic Alexandre , Bertolino Philippe , Raverot Gérald
Published: October 2022

Pituitary adenomas (PAs) are neoplasms derived from the endocrine cells of the anterior pituitary gland. Most frequently, they are benign tumors, but may sometimes display an aggressive course, and in some cases metastasize. Their biology, including their wide range of behavior, is only partly understood. In terms of therapeutic targeting, most PAs are easily treated with available medical treatments, surgery, and sometimes radiotherapy. Nevertheless, gonadotroph adenomas lack medical therapeutic options, and treatment of aggressive PAs and pituitary carcinomas remains challenging. Here, we present an overview of the implications of the tumor microenvironment in PAs, reviewing its composition and function, as well as published cases that have been treated thus far using tumor microenvironment–targeting therapies. Additionally, we discuss emerging views, such as the concept of nonangiogenic tumors, and present perspectives regarding treatments that may represent future potential therapeutic options. Tumor-infiltrating lymphocytes, tumor-associated macrophages, folliculostellate cells, tumor-associated fibroblasts, angiogenesis, as well as the extracellular matrix and its remodeling, all have complex roles in the biology of PAs. They have been linked to hormone production/secretion, size, invasion, proliferation, progression/recurrence, and treatment response in PAs. From a therapeutic perspective, immune-checkpoint inhibitors and bevacizumab have already shown a degree of efficacy in aggressive PAs and pituitary carcinomas, and the use of numerous other tumor microenvironment-targeting therapies can be foreseen. In conclusion, similar to other cancers, understanding the tumor microenvironment improves our understanding of PA biology beyond genetics and epigenetics, and constitutes an important tool for developing future therapies.
Surface Relations
Authors: Huang Vivian L.
Published: October 2022

In Surface Relations Vivian L. Huang traces how Asian and Asian American artists have strategically reworked the pernicious stereotype of inscrutability as a dynamic antiracist, feminist, and queer form of resistance. Following inscrutability in literature, visual culture, and performance art since 1965, Huang articulates how Asian American artists take up the aesthetics of Asian inscrutability—such as invisibility, silence, unreliability, flatness, and withholding—to express Asian American life. Through analyses of diverse works by performance artists (Tehching Hsieh, Baseera Khan, Emma Sulkowicz, Tseng Kwong Chi), writers (Kim Fu, Kai Cheng Thom, Monique Truong), and video, multimedia, and conceptual artists (Laurel Nakadate, Yoko Ono, Mika Tajima), Huang challenges neoliberal narratives of assimilation that erase Asianness. By using sound, touch, and affect, these artists and writers create new frameworks for affirming Asianness as a source of political and social critique and innovative forms of life and creativity.

Surface crawling and pedal surface collecting in aquatic gastropods: A case of scientific amnesia
Authors: Peters Winfried S.
Published: October 2022

Aquatic gastropods, both freshwater and marine, often crawl along the water surface with the sole of the foot facing upward. Differential regulation of the activity of cilia on the sole turns the gliding mechanism into pedal surface collecting, by which food particles floating on the water are collected on the sole. Over the last 300 years, surface crawling and pedal surface collecting have been studied in numerous species, but the accumulated knowledge has fallen victim to scientific amnesia. Today, pedal surface collecting usually is considered a unique behaviour that evolved in the family Ampullariidae (Caenogastropoda), which includes the genus Pomacea with some of the globally worst invasive pests. Consequently it may appear feasible to tackle invasive Pomacea species specifically by delivering molluscicides via the water surface. Based on a review of our forgotten literature, I here argue that such an approach would have potentially devastating, unintended effects on native gastropod faunas.

Alignment of the synthesis of qualitative data (SQD) model, technology self-efficacy and TPACK Core measures in preparing pre-service teachers to integrate technology
Authors: Christensen Rhonda , Trevisan Ottavia
Published: October 2022

Preparing pre-service teachers to integrate technology in their future classrooms is a complex endeavor. Several factors known to affect the use of technology in the classroom include technology knowledge and skills, positive attitudes toward integrating technology, pedagogical expertise with technology and content knowledge in one or more disciplines. One strategy that has been used in many educator preparation programs has been to create a course that teaches how to integrate technology. Measuring the impact of these types of courses is important in determining whether they are meeting the needs of the pre-service teachers in their pursuit to integrate technology in a meaningful and effective way. This paper reports on the measurement and alignment of three aspects that impact pre-service technology integration - technology self-efficacy, strategies and experiences provided by the preparation programs, and the intersection of technology, content knowledge and pedagogy. Pre-service participants in a semester-long course focused on integrating technology gained significantly from pre to post on each of the scales, demonstrating an increase in technology self-efficacy, experiences related to technology during their program and confidence in fusing technology, content knowledge and pedagogy. In addition, the three measures focused on different areas of technology integration aligned to show relationships of the attributes important for using technology in their future classrooms.
The Great Economic Crisis in Poland (1929–1935) in the Context of the Global Crisis
Authors: Klimiuk Zbigniew
Published: October 2022

The aim of the article was to analyze the causes and consequences of the great economic crisis in Poland in the context of the world economy and the global crisis. The first symptoms of the crisis became evident in June 1929, when production began to decline, and in August that year price drop began. After these events, the economic situation in Poland was systematically deteriorating. The year 1935 can be considered the end of the crisis in Poland, despite the fact that the industrial crisis began to break through gradually already in 1933. The great economic crisis was a global phenomenon, even though it did not start in all countries at the same time. It depended on the internal economic situation of each of them. It stood out against the background of previous economic crises due to the fact that only the introduction of state interventionism in the form of the “New Deal” program in the USA brought about an improvement in the situation, and therefore, in 1933, some economic recovery began in the world. However, in some parts of the world (including Poland), due to the specific features of their economies, the crisis lasted until 1935. The crisis of 1929–1935 was rightly called “the great crisis”, not only because of economic problems, but also due to political consequences, i.e., the strengthening of totalitarian systems in Western Europe and the growing importance of the communist movement around the world (the USSR was the only country not affected by its consequences). The great economic crisis was characterized by:

longevity – in industrial countries it lasted until 1933, and in agricultural countries until 1935;

depth of impact – it covered all areas of the economy: industry, agriculture, domestic and foreign trade, transport, monetary and credit system;

wide geographic scope – it covered all countries of the world connected with the world capitalist system and capitalist economies;

the scale of the decline in economic growth rates – in the history of economic crises to date, the world economy has not experienced such a deep collapse and stagnation.

Welcoming a fresh approach to women's health
Authors: Meadows Alison
Published: October 2022

For decades, UK healthcare has been dubbed an institution made by men for men, but the NHS is on the cusp of an integral change. While significant disparities between healthcare for women and men remain, a shift in political attitude, supported by a recognition that women and men have different health needs throughout their lives, should herald a new era of healthcare for women.

The challenge is not only in changing clinician awareness and understanding and creating better, more relevant pathways for female-specific health issues, but also encouraging women to demand better health outcomes, from puberty through fertility, menopause and beyond. Better information, combined with tailored, relevant service delivery, will be key to achieving the early intervention that underlines the preventative care model.

Alison Meadows, joint CEO, Priority Digital Health, celebrates the change and outlines the importance of a digital solutions platform that can integrate multiple health and wellbeing services to engage, educate and empower women of every age and facilitate better patient outcomes.

There are at least 221 species recorded as parasitoids on 108 lixine species. Records on 12 host-parasitoid associations seem to be questable or based on misidentifications. Most common hosts are species of two genera: Lixus (112 parasitoid species) and Larinus (43). All actually known parasitoids of Lixinae are dipterans (belonging to three families) and hymenopterans (15 families). The latter listed as parasitoids of no less than 102 lixine species (94.4%) and 22 hosts (19.4%) associated with Diptera. Six lixine species associated with dipterans only. Most common parasitoids are braconids. Four parasitoid species have the most extensive list of the hosts: Exeristes roborator (at least 29 host species), Cerceris tuberculata (12), Bracon urinator (11) and Zeuxia cinerea (10). Parasitoid complex of some hosts can include more than 10 (to 44!) species. Information contained in catalogue will be helpful for programs of effective biological control of economic important pests and weeds.
Analyzing the impact of medium access control protocol design and control-plane uplink in asymmetric RF/OWC networks with RF congestion

Published: October 2022

As the demand for wireless capacity continues to grow, highly directional wireless communication technologies have the potential to provide massive gains in area spectral efficiency. However, novel challenges arise when considering bidirectional connectivity and multi-cell/multi-user systems with highly directional links. Some of these challenges can be alleviated with the introduction of asymmetric connectivity where the highly directional links are used solely for downlink transmission. As an example, we consider asymmetric links with an optical wireless communication (OWC) downlink and sub-6 GHz RF uplink. More specifically, we consider visible light communication as an instance of OWC, although the presented analysis and validation are applicable to alternative OWC technologies and other simplex downlink transmission technologies. While asymmetric connectivity has been previously demonstrated in scenarios like this, the impact of control-plane asymmetry has not been explored, to our knowledge. In this paper, we first introduce the novel challenges related to local handshaking in wireless networks with control-plane asymmetry. We then develop a theoretical framework for throughput analysis in a network where the sub-6 GHz RF channel is shared between a conventional RF link and an asymmetric RF/OWC link. This analysis is validated via simulation and verified in a testbed system using Mango WARP3 software defined radios and a commercially available RF access point. Finally, we use the derived throughput equations to analyze the impact of various protocol parameters and demonstrate one potential use of the derived equations to evaluate sum throughput in the presence of an unreliable OWC link.

The complex vector beams yield up an abundance of polarization information that has not yet been well utilized in information encoding. In this paper, we propose a polarization encoding scheme with the non-orthogonal polarization states using a stationary vector beam. Recognizing those non-orthogonal polarization states is assisted by the structured patterns of the single vector beams under different polarization projections. We show that one can achieve different capacities of encoding bits by changing the step of the polarization angle with the single vector beam. We also demonstrate the non-orthogonal polarization encoding scheme can be well decoded with the machine learning classification algorithm. A 64×64 gray image is successfully transmitted by using 4 bits/symbol encoding-decoding scheme with 99.94 % transmission accuracy. Besides, by extending the encoding-decoding scheme to 8 bits/symbol based on the same single vector beam, we achieve a higher transmission rate with 65.58% transmission accuracy. Our work holds promise for small-angle non-orthogonal polarization encoding for free-space optical communications.
Depth-assisted calibration on learning-based factorization for a compressive light field display

Published: October 2022

Due to the widespread applications of high-dimensional representations in many fields, the three-dimension (3D) display technique is increasingly being used for commercial purpose in a holographic-like and immersive demonstration. However, the visual discomfort and fatigue of 3D head mounts demonstrate the limits of usage in the sphere of marketing. The compressive light field (CLF) display is capable of providing binocular and motion parallaxes by stacking multiple liquid crystal screens without any extra accessories. It leverages optical viewpoint fusion to bring an immersive and visual-pleasing experience for viewers. Unfortunately, its practical application has been limited by processing complexity and reconstruction performance. In this paper, we propose a dual-guided learning-based factorization on polarization-based CLF display with depth-assisted calibration (DAC). This substantially improves the visual performance of factorization in real-time processing. In detail, we first take advantage of a dual-guided network structure under the constraints of reconstructed and viewing images. Additionally, by utilizing the proposed DAC, we distribute each pixel on displayed screens following the real depth. Furthermore, the subjective performance is increased by using a Gauss-distribution-based weighting (GDBW) toward the concentration of the observer’s angular position. Experimental results illustrate the improved performance in qualitative and quantitative aspects over other competitive methods. A CLF prototype is assembled to verify the practicality of our factorization.
Pump-guided nonlinear film for phase conjugation
Authors: Fu Pengyu , Li Yue
Published: October 2022

It is known that phase conjugation technique is achieved by the nonlinearity of materials, and widely adopted in various applications, such as high-resolution imaging, signal amplification, and target detecting. Here, we have proposed a field-enhancement method for the degenerate four wave mixing (FWM) for phase conjugation purpose. In this method, a thin film waveguide with nonlinear property is utilized to confine and guide the pumps, achieving the enhanced FWM within a flexible structure. Compared to existing degenerate FWM methods, three merits are introduced by the proposed pump-guided nonlinear film. First, the pump is confined and guided in the nonlinear waveguide, and the pump energy is concentrated to achieve high power level of the phase-conjugated signals. Second, less pump energy leaks out from the thin film, with less interference to the phase-conjugated signals. The last one is that pump-guided film can be engineered into flexible shapes for different practical applications. Based on these advantages, the phase conjugation property is numerically verified for high-resolution image reconstruction, even with damping of waveguide or in the presence of the metallic particles and the dielectric blocks.

Published: October 2022

Dynamic illumination using tunable freeform arrays can enable spatial light distributions of variable size with high uniformity from non-uniform sources through relatively small opposing lateral shifts applied to the freeform components. We present the design, manufacturing, and characterization of a tunable LED-based illuminator using custom freeform Alvarez arrays with commercially available optics to shorten the manufacturing cycle. The optomechanical design and manufacturing of the Alvarez lens arrays and mounting parts are presented in detail. The optical performance of the system is evaluated and compared with simulation results using a custom camera-based test station. Experimental results demonstrate and confirm the dynamic illumination concept with good uniformity.
Bias voltage-tuned hot-electron optical sensing with planar Au-MoS2-Au junction

Published: October 2022

Harvesting photoexcited hot electrons in metals promises a number of benefits in optical sensing. In practice, hot-electron optical sensors with tunable performance in electrical sensitivity are still absent. Herein, we propose a design to realize tunable hot-electron optical sensing. The proposed device consists of a one-dimensional grating deposited on a planar Au-MoS2-Au junction that is used for efficient hot-electron harvesting. Photoelectric simulations show that when grating-assisted plasmonic resonance is excited, bias voltage between two Au layers can be used to manipulate the magnitude and polarity of responsivity at the working wavelength. Therefore, the change in responsivity that originates from the change in refractive index of analyte in which the device is immersed can also be tuned by applied voltage. It is found that when bias voltage is 1 V, the electrical sensitivity doubled compared with that when applied voltage is absent. We believe the bias voltage-tuned strategy that is applied to planar hot-electron harvesting junctions facilitates the development of optical sensing.
