A transit map for micro-scale urban development in Alexandria, Egypt
Authors: H. Seoudy Mohamed , El Menshawy Adel , El Adawy Amr
Published: May 2023

Background: Due to Egypt's strategic location among countries, transportation is one of the most significant development sectors because it plays a major part in today's economy and society and has a large influence on growth and employment. Over the years, the Egyptian General Organisation of Physical Planning (GOPP) has prepared strategic general urban plans in collaboration with local and foreign organisations, including transportation plans. The constant focus of authorities on strategic plans and their inability to implement them on schedule are a major issue. In other words, they always take development from a distant perspective and do not deal with the main problem that exists within cities, as the existing micro-scale transit built environments (MSTBEs) of cities are not ready due to a lack of transit-oriented communities (TOCs), sustainably developed transit supply systems, and mobility hubs.

Methods: The "Enhanced MSTBE Phases" methodology is used for the key elements of the study design used in this research, depending on data collection, approvals, techniques, and analysis methods. As a case study, these key elements are in the documentation, analysis, and development of the Muharram Bek El Mowkaf El Gedid Mobility Hub (MBMH) and the 800 m radius around it.

Results: The results indicate that Enhanced MSTBE Phases led to the establishment of the MBMH and the 800 m radius surrounding it as a sustainable MSTBE in Alexandria, Egypt, which is chosen as the case study.

Conclusions: The development of this MSTBE is a catalyst for future effects that will have a long-term impact on meso-scale and, ultimately, macro-scale transit built environments.
“Gilead is within you”: a theocratic narrative setting of cultural memory in Atwood’s The Testaments
Authors: Yadav Manshi , Arora Palak
Published: May 2023

This article attempts to explore the synthetic relationship between group identities and their effects on cultural memory in Margaret Atwood's The Testaments. It will investigate how Atwood's dystopian fiction conspicuously weaves threads of cultural identity in the totalitarian society. While examining the work, the researchers found three forms of Memory Figures channelizing society: Architecture and time, Identical groupings, and Language. With significant attention to the prequel, The Handmaid's Tale, this article will consider The Testaments for the dissection of hard-wired cultural memory formation. This article focuses on how a politically unsettled society of Gilead, through its Memory Figures, inscribes a cultural narrative while instructing individual memories. Atwood's usage of these Memory Figures to achieve a theocratic regime has been scrutinized in this article. The Architecture of Gilead was given an intrusive wall of glass, where the symbol of eyes prevails, to externalize the surveillance of God on each one of its citizens, thereby forming a cultural memory of subjectivity. To make the citizens identify with groups, this theocratic regime specifies roles to citizens according to their rank for men and according to reproductive efficiency for women. Keeping in view the relevance of language in forming cultural memory, Atwood prescribed a set of greetings such as 'under his eyes,' and 'praise be' to make profound imprints on the individual memory of citizens, which has been discussed in the study. These three Memory Figures simultaneously form collective memory imprints on the citizens of Gilead, which in time became inherent cultural memories. This article explores how, by politicizing the issue of cultural memory in The Testaments, Atwood taps into the agency of people and establishes language control (communicative) to form the cultural memory narrative.
Benefits, anxieties, acceptance, and barriers to the new injectable contraceptive DMPA-SC (Sayana Press): Clients’ perceptions in Sindh, Pakistan
Authors: Veesar Ghulam Yaseen , Lashari Talib , Fida Roshan , Veesar Mansoor Ahmed
Published: May 2023

Background: Injections are Pakistan's third most preferred contraceptive method because of their convenience. They represent a 2.5% share of the contraceptive prevalence rate (CPR) and contribute 10% to the current CPR. However, injections require a clinical setting or a healthcare provider for administration. A new method of subcutaneous presentation of depot medroxyprogesterone acetate (DMPA-SC), namely Sayana Press in Uniject™, has been introduced, which can be administered in nonclinical settings or self-administered by trained women. This study examined clients’ perceptions of the current depot medroxyprogesterone acetate-intramuscular injection (DMPA-IM) and its accessibility, availability, affordability, advantages, and disadvantages. In addition, it explored the benefits, barriers, and challenges regarding the new method of DMPA-SC (Sayana Press), especially considering self-injection.

Methods: The study was conducted in Sindh, Pakistan. Three focus group discussions were conducted with 9–13 female participants with different demographic characteristics. A semi-structured questionnaire was used. The discussion was recorded, transcribed, and translated from Urdu or Sindhi to English. Transcripts were coded precisely, and data analysis was performed using NVivo software.

Results: Participants expressed moderate fear of self-injection and risk of an inaccurate prick, suggesting that DMPA-SC acceptance may not be challenging at a community level. They appreciated free services at public health facilities, as the affordability of private facilities may be challenging for those with low income. Most participants agreed to pay PKR 50–300 (approximately 1 USD or less) as service charges for a private facility, while some agreed to pay for transportation costs when lacking alternative methods.

Conclusions: DMPA-SC is a valuable alternative, provided its challenges are adequately addressed. Information about self-injection contraceptives is currently limited, and shared self-administration may be difficult without adequate training and counseling. Nevertheless, clients prefer the self-injection method for family planning to avoid transportation and private service charges.
Depression, sleep quality, and body image disturbances among pregnant women in India: a cross-sectional study
Authors: Kadam Kranti S. , Anvekar Aditya R. , Unnithan Vishnu B.
Published: May 2023

Background: Pregnancy is associated with a number of physical, emotional, and biological changes that can exacerbate maternal psychological disturbances, such as body image concerns and depression. Sleep disturbances during pregnancy can also have adverse impacts. This study aimed to determine the prevalence of depression, sleep disturbances, and body image concerns among pregnant women. The study also examined the relationship between these factors and pregnancy-related variables, such as bad obstetric history and whether the pregnancies were unplanned.Methods: A cross-sectional study of 146 pregnant patients was conducted at a tertiary care center over 15 months. The patients were administered the Beck Depression Inventory, Pittsburgh Sleep Quality Index, and Body Image Concern Inventory questionnaires. Contingency tables, Fisher exact test, and Spearman correlation were used to identify underlying relationships.Results: The prevalence of depression was 22.6%. Although body image disturbance was noted in only 2.7% of patients, 46.6% had poor sleep quality. Poor sleep was associated with primigravida status. Bad obstetric history and unplanned pregnancy were associated with depression. Depression was found to be significantly correlated with body image disturbances and poor sleep quality. Conclusion: Psychiatric disorders were prevalent during pregnancy. This study highlights the importance of screening for depression in pregnant patients. Counselling and caregiver education can be useful for mitigating psychological disturbances. Management of pregnancies by multidisciplinary teams that include psychiatrists could be immensely useful in improving the pregnancy experiences of patients.
The fate of sacred places in Nagorny Karabakh as a symbol of unsuccessful conflict transformation
Authors: Horak Slavomir , Tomáš Hoch
Published: May 2023

The 2020 war in Nagorny Karabakh brought not merely a shift in the actual borders in the southern Caucasus; it also led to a change in control over several religious buildings or places that had become sacralized as symbols for one or the other side. Using selected examples of sacred places associated with Armenian or Azerbaijani historical memory, this article seeks to cast light on the fate of cultural monuments in war and its aftermath. In connection with the long-lasting conflict, these monuments are forced to undergo a cycle of sacralization, desacralization and reinterpretation of their origins and functions, depending on the approach taken by the winning side. Churches, monasteries and mosques in Nagorny Karabakh thus serve as sad examples of unsuccessful conflict transformation.
Towards the improvement of bilingual education in Andalusia: The Language Assistant perspective.
Authors: Travé González Gabriel H. , Vinluan Ian Paolo , Soto Rosales Antonio
Published: May 2023

La enseñanza bilingüe se extiende por una amplia red de centros andaluces en las que desempeñan sus funciones auxiliares de conversación extranjeros. El estudio se acerca a los procesos de enseñanza/ aprendizaje que acontecen en las aulas bilingües y cómo se podrían mejorar según los auxiliares. Para la obtención de información se elaboró un cuestionario con 81 ítems que se envió a la totalidad de los centros bilingües andaluces, obteniendo 279 respuestas. El análisis de los datos cuantitativos se realizó a través de SPSS y los cualitativos fueron codificados con ATLAS.ti. Entre los resultados destacan tres categorías emergentes para la mejora de la enseñanza bilingüe vinculadas con el enfoque AICLE, la metodología y el uso de los idiomas en el aula. Los auxiliares validan el enfoque AICLE aunque reclaman una mejor adaptación del uso de la lengua extranjera para la enseñanza del contenido, especialmente cuando aumenta su complejidad. Con respecto a la metodología de aula se describen prácticas docentes expositivas, al primar la actividad del docente frente a la del alumnado, así como el uso generalizado del libro de texto. Con respecto al uso de los idiomas se atestigua el prominente papel del español, intensificado en aquellos casos en los que la competencia en L2 de docentes y alumnado es menor. Las conclusiones apuntan a la pertinencia de reforzar las dimensiones metodológicas y lingüísticas, siendo por tanto necesarios esfuerzos renovados en cuanto a la formación inicial y permanente.

Optimal Pricing with a Single Point
Authors: Allouah Amine , Bahamou Achraf , Besbes Omar
Published: May 2023

Historical data are typically limited. We study the following fundamental data-driven pricing problem. How can/should a decision maker price its product based on data at a single historical price? How valuable is such data? We consider a decision maker who optimizes over (potentially randomized) pricing policies to maximize the worst-case ratio of the garnered revenue compared to an oracle with full knowledge of the distribution of values, when the latter is only assumed to belong to a broad nonparametric set. In particular, our framework applies to the widely used regular and monotone nondecreasing hazard rate (mhr) classes of distributions. For settings where the seller knows the exact probability of sale associated with one historical price or only a confidence interval for it, we fully characterize optimal performance and near-optimal pricing algorithms that adjust to the information at hand. The framework we develop is general and allows to characterize optimal performance for deterministic or more general randomized mechanisms and leads to fundamental novel insights on the value of data for pricing. As examples, against mhr distributions, we show that it is possible to guarantee 85% of oracle performance if one knows that half of the customers have bought at the historical price, and if only 1% of the customers bought, it still possible to guarantee 51% of oracle performance.

The Information in Hedge Fund Option Holdings
Authors: Anand Amber , Hua Jian , Puckett Andy
Published: May 2023

We provide new insights on how hedge funds use options and short-selling channels to trade on their negative information. Bearish information in hedge fund option positions is economically large, distinct from information in short interest, and it is the combination of option positions and short interest that provides the strongest information signal. A portfolio of stocks with high short interest and bearish hedge fund option positions predicts negative abnormal returns that are more than four times as large as the portfolio with high short interest and bullish options positions. The information in hedge fund option positions increases during periods of market stress, whereas that in short interest does not. This increase is concentrated in capital-constrained hedge funds, suggesting that options provide a channel for capital-constrained hedge funds to exploit their information advantage.

The Challenge of Maintaining Passion for Work over Time: A Daily Perspective on Passion and Emotional Exhaustion
Authors: Bredehorst Joy , Krautter Kai , Meuris Jirs , Jachimowicz Jon M.
Published: May 2023

Passion for work is highly coveted, but many employees report struggling to maintain their passion over time. In the current research, we explain the challenge of pursuing passion by conceptualizing passion as an attribute with temporal variation. Viewed through a daily lens, we argue that self-regulation plays a critical role in understanding the challenges underlying the daily maintenance of passion. More specifically, we hypothesize that—unless employees adequately regulate their passion on any given day—higher levels of passion will lead them to invest more time and energy into their work, decreasing their psychological detachment from work after the workday, and consequently resulting in higher levels of emotional exhaustion the next day. Higher levels of emotional exhaustion on a given day subsequently prompt a greater need for recovery, shifting employees’ focus away from devoting time and energy into work, thereby eroding their passion on the following day. Two daily-diary studies covering 30 and 10 consecutive working days provided support for our predictions (Ntotal= 798; ktotal= 15,702). Employees who felt more in charge of their passion on any given day engaged in self-regulation during their workday, increasing their psychological detachment from work and subsequently being less likely to suffer the detrimental consequences of higher daily passion. Our theory and findings demonstrate the daily interplay between passion and emotional exhaustion and specify why passion may be self-limiting unless employees adequately manage it, reflecting a challenge they need to navigate each day in pursuing their passion.

Monkeypox in a renal transplant recipient: is it a hazard for immunocompromised patients?
Authors: Heis Farah , Heis Mohamed , Khan Mahrukh , Ashok Manjula
Published: May 2023

There has been a recent outbreak of monkeypox in the United States, mostly among men who have sex with men (MSM). It seems to be a self-limiting disease but can be potentially serious in immunocompromised patients. Monkeypox infection is transmitted mainly through skin-to-skin contact and possibly seminal and vaginal fluids. Very few cases of monkeypox infection in immunocompromised patients have been published in the literature. We report a case of infection in a renal transplant recipient, and describe the clinical course and outcome.
Cardiac arrest due to out-of-hospital pulmonary embolism during pregnancy: successful thrombolysis
Authors: Söderberg Mårten , Smedberg Erica , Lindqvist Pelle G.
Published: May 2023

Introduction: Pulmonary embolism (PE) is a rare, severe complication in pregnancy, in which case thrombolysis can be lifesaving but has risks. We aim to highlight actions specific to pregnant women. Case Description: A 24-week pregnant woman developed shortness of breath and experienced sudden cardiac arrest. Cardiopulmonary resuscitation (CPR) was begun immediately in the ambulance and a perimortem caesarean section was performed upon arrival at hospital, but the new-born died. After 55 minutes of CPR, bedside echocardiography revealed right ventricular strain and thrombolysis was given. The uterus was bandaged to minimize blood loss. After massive transfusions and correction of haemostasis, a hysterectomy was performed due to inability of the uterus to contract. After 3 weeks, the patient was discharged in good health and placed on continuous anticoagulant treatment with warfarin. Discussion: Approximately 3% of all out-of-hospital cardiac arrest cases are due to PE. Among the few patients who survive at the scene, thrombolysis can be lifesaving and should be considered in pregnant women with unstable PE. Prompt collaborative diagnostic work-up in the emergency room is necessary. In a pregnant woman with cardiac arrest, a perimortem caesarean section improves the chances of both maternal and fetal survival. Conclusion: Thrombolysis should be considered for patients with PE in pregnancy with the same indications as in a non-pregnant woman. In case of survival, there is profuse bleeding with need for massive transfusions and haemostasis correction. Despite being in very poor condition, the above patient survived and was fully restored to health.
The subordination of black people in the United States Toni Morrison’s novel, Beloved
Authors: Wajiran Wajiran , Septiani Nur Alifah
Published: May 2023

This paper is aimed at discussing Morrison’s novel, Beloved dealing with the issues of human discrimination in the United States. Morrison is a writer who voices human values through discussions on issues of discrimination due to ethnicity, race, and skin color, especially that conducted against black people. She was instrumental in fighting for civil and political rights for black people in the United States, especially in Ohio. This study involves the theory of genetic structuralism to understand the concept of white supremacy. This is intended to see the relationship between white supremacy with the issues of social discrimination in the context of black people in the United States depicted in the novel. The issue of race and social class has always stood out in various groups of people. Even though society has progressed the issues of race, religion, and skin color still cause intergroup conflicts due to various interests. As depicted in the novel, black people are generally side-lined and considered only half human. Consequently, black citizens in the United States are associated with slavery or manual labor).
The Representation of Mothers as Bearers of Culture in Three Short Stories from Indonesia
Authors: Kalauserang Esther Deborah
Published: May 2023

Mothers occupy an important place in the smallest scale of the society, namely, the family. Therefore, the purpose of this research is to examine the representation of mothers as bearers of culture from three Indonesian short stories by finding out: 1) how the Indonesian mothers are portrayed in the three short stories; and, 2) how the Indonesian mothers in the three short stories are portrayed as bearers of culture. The approach employed in this research is literary descriptive analysis while applying the theory of motherhood and culture to answer the first and second research objective. The result shows that the Indonesian mothers are portrayed as individuals who are self-sacrificing, and those with the capacity to act as a bridge between individuals. Furthermore, the Indonesian mothers are portrayed as bearers of culture through their association with the process of baby-naming in accordance with their cultural identity, through their process of traditional or religious burial rites, and through language.

Published: May 2023

O objetivo deste estudo foi traçar um panorama das violências vivenciadas e temidas por estudantes no contexto universitário. Buscou-se descrever as frequências dessas violências, bem como a percepção dos alunos sobre suporte psicológico da Universidade e denúncia do agressor. Os dados foram obtidos por meio de questionário online e sistematizados com o auxílio do software SPSS (versão 2.3). Utilizou-se análises descritivas de frequência, média, desvio padrão, quartis e teste-t. Em geral, as médias de vivência de violência foram baixas, com maior incidência de violência emocional de professor e de colega; mulheres disseram ter sofrido mais violência em relação aos homens. As médias do medo foram altas, especialmente para mulheres, alunos mais jovens, com menor renda salarial e que relataram já ter sofrido algum tipo de violência na universidade. A universidade se mostrou um local onde parece ocorrer menos violência do que se teme. Estratégias de ação das universidades são necessárias para uma cultura solidária entre estudantes, professores e funcionários e para a oferta de suporte psicológico aos estudantes.

Características Cognitivas e Comportamentais Associadas à Distrofia Muscular de Duchenne: Revisão Integrativa
Authors: Arruda Clara Monte , Chaves Dalva Rafaela Pessoa , Biermann Mariana Costa
Published: May 2023

A Distrofia Muscular de Duchenne (DMD) é uma doença neuromuscular progressiva recessiva causada por mutações genéticas ligadas ao cromossomo X. Além do enfraquecimento muscular progressivo, a condição é associada a alterações neuropsicológicas. O objetivo deste estudo foi realizar uma revisão sistematizada da temática, para investigar os aspectos cognitivos e comportamentais associados à DMD pela literatura, nos últimos dez anos (2011-2021). Realizou-se uma revisão integrativa da literatura, com o propósito de sintetizar e analisar o conhecimento sobre o tema no campo científico, sendo efetuada busca nas bases de dados e motores de busca Science Direct, SciELO, PubMed e BVS. Após consideração dos critérios de inclusão e exclusão, foram selecionados 29 artigos para análise. Os resultados endossaram que alterações cognitivas e do neurodesenvolvimento, bem como de problemas comportamentais parecem ser mais prováveis na DMD, em comparação com a população geral. Verificou-se escassez de estudos empíricos brasileiros e a necessidade de avaliar e intervir nos âmbitos neuropsicológico e psicossocial, de forma precoce, contínua e multidisciplinar, no intuito de atender às necessidades desse grupo.

Authors: França Tatiane , Hohendorff Jean Von , Silva Ana Claudia Pinto da , Costa Carlos
Published: May 2023

Este estudo qualitativo e transversal investigou as percepções e vivências dos/as psicólogos/as sobre o uso da punição física em crianças. Participaram do estudo 13 psicólogos/as brasileiros/as, que responderam a um questionário sociodemográfico on-line, um roteiro de entrevista e vinhetas de situação-problema. A análise de conteúdo revelou duas categorias: Ambivalência nas percepções sobre o uso da punição física: A palmada não é uma forma de agressão?; e Reprodução da punição física geração após geração: a forma de educar mudou?. Constataram-se percepções endossando o uso da punição física e experiências pessoais de punição física na infância, mas vários participantes buscam não repetir com os filhos e são desfavoráveis a todos os níveis dessa prática. Participantes favoráveis ao uso, principalmente da palmada, demonstraram desconhecimento da sua ineficácia enquanto método educativo e de seus efeitos prejudiciais. A transgeracionalidade e a naturalização da palmada foram motivos salientados para a persistência do uso da punição física. São necessárias capacitações a psicólogos/as e estudantes sobre os prejuízos e alternativas à punição física em crianças.
Entre Silêncios e Formas: Censura e Pós-Censura na Arte Brasileira Contemporânea
Authors: Rech Morgana , Birman Joel
Published: May 2023

O artigo trata da censura na arte brasileira contemporânea que, desde 2016, com o encerramento da exposição Queermuseu, marcou o retorno de um tipo de ato censório (pós-censura) que difere da censura praticada desde a redemocratização. Para tal, apresentamos um retorno até as formas da censura institucionalizada na Ditadura Militar (censura clássica) e sua dissolução na cultura. Com apoio em trechos de algumas entrevistas que realizamos em nosso campo empírico, a articulação teórica é feita entre os campos da estética, da política e da psicanálise, com apoio principal nas teorias de Michel Foucault, Jacques Rancière e Sigmund Freud. Argumentamos que a censura expõe de forma inequívoca o fato de que a criação responde às transformações no campo político que, por sua vez, geram novas formas artísticas. Conclui-se que a prinicipal marca da pós-censura é a imprecisão da figura do censor e que, tanto num como noutro contexto, a censura impede o exercício da função social da arte, questão que deve ser observada na psicanálise para além da subjetividade individual do artista.

Published: May 2023

We analyzed light confinement in circular step-index cores of tellurite and silica fibers through numerical calculations and also examined crosstalk between the fundamental modes of cores in multicore fibers. Our analysis showed that tellurite fibers have a pixel density about 2.2 times higher and a brightness about 1.4 times brighter than silica fibers. As a result, tellurite multicore image fibers have the potential to provide improved resolution and brightness for near-infrared image transportation compared with silica fibers.

Non-Hermitian optics is a burgeoning field at the intersection of
quantum physics, electrodynamics, and nanophotonics. It provides a new
perspective of the role of gain and loss in optical systems.
Leveraging the advanced designs inspired by non-Hermitian physics,
classical optical platforms have been widely investigated to unveil
novel physical concepts, such as parity-time symmetry and exceptional
points, which have no counterparts in the conventional Hermitian
settings. These investigations have yielded a plethora of new
phenomena in optical wave scattering, optical sensing, and nonlinear
optical processes. Non-Hermitian effects also have a profound impact
on the lasing behaviors in the semiclassical framework of lasers,
allowing for novel ways to engineer single-mode lasers, chiral laser
emission, laser noise, linewidth, etc. Furthermore, over recent years,
there has been increasing interest in the explorations of
non-Hermitian physics in quantum optics, which addresses photon
statistics, entanglement, decoherence, and quantum sensing in
non-Hermitian systems. In this review, we review the most recent
theoretical and experimental advances in non-Hermitian optics and
photonics, covering the significant progress in both classical and
quantum optics regimes.
Surface weak scratch detection for optical elements based on a multimodal imaging system and a deep encoder–decoder network

Published: May 2023

The detection of surface weak scratches is an intractable but vital task in optics-centered industries. However, the intrinsic characteristics of weak scratches, such as a narrow width, long span, and shallow depth, make it extremely difficult to effectively detect these scratches. In this paper, we tackle this issue from two perspectives. First, a multimodal microscopic imaging system is created by combining discrete multispectral illumination with linear polarization. Imaging experiments demonstrated that this system could highlight more scratch details, improve image clarity, and alleviate the image blur problem induced by wide spectrum scattered lights. Second, a scratch-oriented U-shaped deep encoder–decoder network equipped with optimized residual encoding modules, serial–parallel multiscale fusion modules, and triple-convolution decoding modules is proposed to segment the weak scratches from a raw image. The detection experiments demonstrate that our model can accurately segment the weak scratches on optical surfaces and achieve better detection performance using significantly fewer parameters compared to similar deep learning models. Meanwhile, experiments on the building crack dataset prove the excellent generalization capability.
Considerations for excess noise measurements of low-k-factor Sb-based avalanche photodiodes

Published: May 2023

In applications where high sensitivity is required, the internal gain mechanism of avalanche photodiodes can provide a performance advantage relative to p-i-n photodiodes. However, this internal gain mechanism leads to an excess noise that scales with gain. This excess noise term can be minimized by using materials systems in which impact ionization is initiated primarily by one carrier type. Recently, two Sb-based materials systems, AlInAsSb and AlGaAsSb, have exhibited exceptionally low excess noise, particularly for III–V compound materials. There are four important considerations that can impact the excess noise measurements in such low-noise materials. These considerations deal with the excess noise factor calculation method, measurement RF frequency, measurement wavelength, and the gain calculation method. In this paper, each of these factors is discussed, and their implications on excess noise are considered.
Replica symmetry breaking in a Rayleigh backscattering-based random fiber laser

Published: May 2023

Replica symmetry breaking (RSB) phase transition is observed in disordered photonics systems. The key requirements to observe RSB are provided by random lasers, i.e., gain and disorder. However, in a random fiber laser (RFL) with scattering provided by Rayleigh scattering of light, the condition of quenched disorder is not established due to environment perturbations. Here, RSB is observed in a Rayleigh backscattering-based RFL, where light scattering is due to the inhomogeneity of the optical fiber refractive index. This is done by using short-cavity erbium-RFL with reduced interaction with the environment. Spectral characterization is made, and narrow mode linewidths are demonstrated. The intensity dynamics and laser mode behavior are analyzed showing the presence of gain competition. The results indicate a connection between the replica symmetry or RSB, Lévy-like behavior of intensities, and the presence or not of correlated laser intensity fluctuations.
Dual-band polarization-independent high quality factor Fano resonances using a twisted tetrameric nanohole slab

Published: May 2023

The Fano profile inspired by bound states in the continuum (BICs) has emerged as an effective approach to obtain high quality factor (QF) resonances. However, achieving polarization-independent high QF Fano resonances through the excitation of BICs is still challenging. Herein, we demonstrate that dual-band polarization-independent high QF Fano resonances can be realized by using a twisted tetrameric nanohole slab (TTNS). By twisting the nanoholes of the tetramerized slab, two quasi-BICs can be transformed into dual-band high QF Fano resonances due to the Brillouin zone folding as well as the symmetry breaking from C4v to C2v of the structure. The variation of the twist angle (θ) significantly alters the location of the Fano resonance in the longer wavelength, but it has slight influence on the Fano resonance in the shorter wavelength. A larger QF corresponds to a larger average electric-field enhancement-factor (AEE) for both of the Fano resonances, but the QF of the Fano resonance at the longer wavelength is more robust to the variation of θ due to its larger scaling rule as QF∼|θ|−6. According to multipole decompositions, Fano resonances at the longer and shorter wavelength correspond to toroidal dipole (TD) mode and hybrid TD-magnetic quadrupole (MQ) mode, respectively. In addition, both the two Fano resonances survive even if the structural parameters are significantly altered, and they exhibit polarization-independent features because the rotational symmetry of the structure can be maintained as θ is varied.

Published: May 2023

The quasi-static temperature and dynamic acoustic signals based on ultra-weak chirped fiber Bragg grating (CFBG) array is proposed and experimentally demonstrated, which can be employed to detect distributed acoustic and temperature signals simultaneously. Distributed temperature sensing (DTS) was realized by cross-correlation operation to measure the spectral drift of each CFBG, and distributed acoustic sensing (DAS) was achieved by gauging the phase difference between adjacent CFBG. Using CFBG as the sensor unit can protect acoustic signals from the fluctuations and drifts induced by temperature change without deterioration of signal-to-noise ratio (SNR). Applying least square mean adaptive filter (AF) can enhance harmonic frequency suppression ratio and increase the SNR of system. In the proof-of-concept experiment the SNR of acoustic signal is higher than 100 dB after the digital filter and frequency response is from 2 Hz to 1.25 kHz with repetition frequency of laser pulses of 10 kHz. Temperature measurement from 30°C to 100°C is achieved with demodulation accuracy of ±0.8°C. The spatial resolution (SR) of two-parameter sensing is 5 m.
High-precision phase retrieval method for speckle suppression based on optimized modulation masks
Authors: Li Xie , Liu Kunpeng , Liu Zhigang , Guo Junkang
Published: May 2023

Traditional methods of coherent diffraction imaging using random masks result in an insufficient difference between the diffraction patterns, making it challenging to form a strong amplitude constraint, causing significant speckle noise in the measurement results. Hence, this study proposes an optimized mask design method combining random and Fresnel masks. Increasing the difference between diffraction intensity patterns enhances the amplitude constraint, suppresses the speckle noise effectively, and improves the phase recovery accuracy. The numerical distribution of the modulation masks is optimized by adjusting the combination ratio of the two mask modes. The simulation and physical experiments show that the reconstruction results of PSNR and SSIM using the proposed method are higher than those using random masks, and the speckle noises are effectively reduced.

Ultrafast ring-cavity thin-disk oscillators combine high output power with the flexibility of generating output either unidirectionally or bidirectionally. Here, we report a Kerr-lens mode-locked ring-cavity Yb:YAG thin-disk oscillator delivering unidirectional 89-fs pulses by inducing additional spectral broadening with nonlinear plates. This is the shortest pulse duration for a ring-cavity mode-locked thin-disk oscillator. Bidirectional mode-locking was also realized. These results lay the foundation for the more efficient generation of high-order harmonics at MHz repetition rates and high-power dual frequency combs.
