Published: September 2024

We present ATLAS, a 512 × 512 single-photon avalanche diode (SPAD) array with embedded autocorrelation computation, implemented in 3D-stacked CMOS technology, suitable for single-photon correlation spectroscopy applications, including diffuse correlation spectroscopy (DCS). The shared per-macropixel SRAM architecture provides a 128 × 128 macropixel resolution, with parallel autocorrelation computation, with a minimum autocorrelation lag-time of 1 µs. We demonstrate the direct, on-chip computation of the autocorrelation function of the sensor, and its capability to resolve changes in decorrelation times typical of body tissue in real time, at long source-detector separations similar to those achieved by the current leading optical modalities for cerebral blood flow monitoring. Finally, we demonstrate the suitability for in-vivo measurements through cuff-occlusion and forehead cardiac signal measurements.
High-fidelity decryption technology for visual cryptography based on incoherent optical polarization XNOR operation
Authors: Wang Jiahui , Lin Wei , Zhang Hao , Liang Hu , Duan Shaoxiang , Yao Yuan , Liu Bo
Published: September 2024

In this paper, we propose an optical high-fidelity decryption technology for Visual Cryptography (VC) based on incoherent optical polarization exclusive NOR (XNOR) operation. The plaintext image is divided into two binary ciphertexts by the Random-Grid-based Visual Secret Sharing (RGVSS) algorithm. These ciphertexts are printed onto the polarizing films with orthogonal polarization. The P- and S-polarizing pixels in the polarizing films represent the “black” and “white” pixels of the ciphertexts, respectively. Due to the optical transmission property of polarizing film, the pixel in the decrypted image appears bright only when the stacked pixels for the two ciphertexts have the same polarizing orientation. High-fidelity image decryption is then achieved. The proposed technology has been successfully demonstrated through simulation and experimentation. Thanks to its advantages of no pixel expansion, incoherent illumination, being free of computer assistance, and flexibility of ciphertext carriers, this method provides a broad prospect for convenient, large-format, high-fidelity information recovery applications for VC.
On-chip broadband Mach-Zehnder interferometer based on a broadband taper-section phase shifter
Authors: Ai Xiheng , Zhang Yang , Hsu Wei-Lun , Veilleux Sylvain , Dagenais Mario
Published: September 2024

In this paper, we propose a new broadband nulling interferometer based on the Si3N4/SiO2 platform which utilizes a π-phase shifter. This π-phase shift multimode interference Mach-Zehnder interferometer (πPS MMI-MZI) leverages a novel low phase shift error (PSE) and broadband taper-section phase shifter (TSPS). For the TSPS, our simulation predicts an unprecedented PSE from 1450 nm to 1650 nm for the two- and three-section TSPS of 1
o
and 0.02
o
, respectively. Our experimental results demonstrate a PSE of 1
o
within a 190 nm bandwidth for the two-section TSPS. A slightly adjusted TSPS gives an even lower PSE of 0.6
o
within a narrower bandwidth of 90 nm. With the help of the TSPS, the πPS MMI-MZI shows a significant improvement in extinction ratio compared to the conventional MMI-MZI. Simulations predict an extinction ratio of 50 dB within a 150 nm bandwidth. Experimental measurements demonstrate a 40 dB extinction ratio within a 100 nm bandwidth. The broadband TSPS, as well as the broadband πPS MMI-MZI, pave the way for novel high performance photonic integrated circuits.
High-speed measurement method for diffraction efficiency of gratings in broad range wavelength based on AOTF
Authors: Xu Xieluyao , Li Wenhao , Jirigalantu  , Yu Hongzhu , Zhang Jiawei , Liang Hongzhi
Published: September 2024

Diffraction efficiency is a critical indicator of grating performance. Traditional single-point measurement methods are slow, often taking several hours to generate a complete diffraction efficiency curve. Existing fast measurement techniques are limited to providing efficiency curves only within the 550–750 nm wavelength range. Therefore, this paper proposes a new high-speed measurement method that leverages an acousto-optic tunable filter (AOTF), an integrating sphere, and a concave mirror to achieve rapid and precise diffraction efficiency measurements. Experimental results demonstrate that for gratings with 300–1200 grooves per millimeter, this method can complete measurements within the 500–1000 nm wavelength range in under one minute. The mean absolute error is less than 2%, with a repeatability error also below 2%.

Published: September 2024

A highly sensitive fiber-optic inclination sensor using a modal interferometer was proposed in the present study, which has a photopolymer embedded in a single-mode-few-mode-single-mode fiber (SMF-FMF-SMF) interferometric structure. The sensing component for inclination measurement consists of a cured ellipsoidal photopolymerized-waveguide (EPW) connecting the ends of the FMF and SMF. The effect of EPW on the transmission spectrum and sensitivity of the sensor is specifically investigated using simulation and experiment. In addition, during the preparation of the sensor, it was found that EPW affects the cladding pattern where the FMF is at a low frequency, and a more stable interference pattern can be obtained by modulating the FMF length. The results demonstrate a notable tilt sensitivity of 4.43 dB per degree within the range of 4.4° to 11.4°. Moreover, a change in inclination angle causes misalignment of the FMF and SMF cores, which results in a variation in fringe contrast (FC), allowing a one-to-one correspondence between fringe contrast and θ to be established over a wider range of 0° to 11.4° with an error of less than 3%. The proposed sensor has low temperature crosstalk and is able to cope with disturbances in complex environments. It is expected to be used for microdeformation monitoring of engineered structures.

Published: September 2024

High-speed silicon traveling-wave Mach-Zehnder modulators (MZMs) modulators are key components to support optical fiber communication. However, one major challenge with all-silicon MZMs is to achieve efficient high-speed electro-optic (EO) modulation. The reported 3 dB bandwidth of silicon MZMs
are generally below 70 GHz, with half-wave voltage (Vπ) around 5 V or larger, which can not support future 200 Gbaud data transmission. Here we break the voltage–bandwidth trade-off limit in silicon MZMs by replacing the doped silicon slab with CMOS compatible transparent electrodes. Benefit from the measured high conductivity, low extinction coefficient, and low refractive index of indium tin oxide (ITO) materials, the microwave dielectric loss of the traveling wave electrode can be greatly reduced. The bandwidth would potentially increase from 40 GHz to 168 GHz, while Vπ and optical insertion loss remains
almost unchanged. According to Si/ITO interface contact states, three operating mode were found, corresponding to Si/ITO ohmic contact, schottky contact and hybrid schottky/ohmic contact, respectively. We comprehensively analysis the Si/ITO interface characteristic, establish a complete high frequency equivalent circuit model. Our proposed transparent electrodes will open a new window for the high-speed silicon photonics platform.

A day for preserving things: Activism, technology and the politics of preservation in the Sarah Records archive
Authors: Evans Alex
Published: September 2024

Sarah Records was an independent label active in Bristol from 1987 to 1995 famous for its many contributions to the UK indie pop scene from bands like Heavenly, the Field Mice and the Orchids. In 2015, the same year that the New Musical Express named Sarah as the second-best independent label of all time, the founders launched a digital archive to share photographs, press-clippings and other artefacts. While Sarah releases were often dismissed by the popular music press at the time as ‘twee’ – perhaps due to the label’s name and the gender of one of its founders – the archive provides a compelling counterstory (Martinez) of the label as an activist organization advancing political causes through its releases, advertisements and more. This article examines the political legacy of Sarah Records, a label that regularly advocated for feminism and socialism through its releases, by considering how its engagement with the press, its use of technology, and now its archive have worked to enact its political ideals and subvert dominant cultures.

Authors: Mohsen Barzegar  , Mohammad Amin Yektaie  , Adeleh Pouyafard
Published: September 2024

BACKGROUND
The removal of plates and screws in maxillofacial surgery following trauma has emerged as a significant concern. Understanding the primary reasons for hardware removal is crucial to enhance patient outcomes and reduce postoperative complications.
METHODS
This retrospective cohort study investigated 109 patients who underwent plate and screw fixation at Shahid Rahnemoun Hospital (Yazd, Iran) from 2011 to 2021. The study included 109 patients who met the inclusion criteria. The primary outcome was to identify and classify the causes necessitating plate and screw removal, which were categorized into four main groups: Pain, Complications, Procedural Problems, and Patient-Initiated Factors. Descriptive statistics were used to summarize the data. One-way analysis of variance and Chi-square or Fisher's exact tests were employed to analyze the associations between variables.
RESULTS
The study population was predominantly male (74.3%), with a mean age of 35.25 ±19.47 years. The time between plate and screw insertion and removal ranged from 14 days to 3 years, while this interval in most of the patients (51.4%) was between six months to one year. The primary reasons for hardware removal were patient-initiated factors (51.4%), followed by procedural problems (24.8%), complications (11.9%), and removals due to pain (11.9%). Except for age, other studied variables were not significantly associated with the removal cause.
CONCLUSIONS
The high prevalence of patient-initiated removals highlights the importance of considering individual preferences and psychological factors in surgical planning. The study emphasizes the need for age-specific considerations and a focus on preventative strategies to reduce infection-related complications.
LUTA POR UM ESPAÇO NA ESCOLA

Published: September 2024

Este trabalho teve como objetivo analisar as políticas públicas educacionais para a educação básica do município de João Pessoa/Paraíba, focando no direito ao acesso e permanência de pessoas trans, travestis e não binárie. Buscamos, por um lado, realizar uma análise de conteúdo do Plano Municipal de Educação, observando os temas e grupos destacados nas ações e planejamentos. Por outro lado, realizamos entrevistas com pessoas trans, travestis e não binárie, considerando a perspectiva discursiva em Foucault, para conhecermos suas experiências passadas enquanto estudantes do ensino fundamental e/ou médio na cidade. No geral, comparando o conteúdo do plano de educação e os relatos das pessoas entrevistadas, percebemos que há uma lacuna no conteúdo da política pública analisada quanto às demandas das populações trans, travesti e não binárie. Nesse contexto, essas pessoas resistem de variadas formas, seja confrontando ou mesmo evitando o contexto escolar, seja inclusive construindo relações dentro desses espaços.

Authors: Sabbá Adria Caroene Queiroz , Resende Gisele Cristina
Published: September 2024

As subjetividades e as sexualidades humanas são construídas nas relações socais e nos processos psicossociais. Nesses processos, a literatura pode ter um papel importante, pois enquanto um artefato cultural, pode repercutir na vida dos leitores, quando estes encontram um significado que se entrelaça com suas vivências, em processos de identificação de si e sua sexualidade. Este estudo buscou entender a representatividade da literatura voltada para o público LGBTQIA+ nas vidas de jovens leitores universitários. O delineamento metodológico foi qualitativo, com entrevistas narrativas semi-estruturadas realizadas com três estudantes. As Análises Temáticas resultaram em três categorias, Importância da literatura para o fortalecimento da identidade, Literatura enquanto recurso de acolhimento na universidade e Saúde mental no público leitor LGBTQIA+. Concluiu-se que a literatura favorecer a compreensão de sua própria identidade, pode ser um recurso de conhecimento, acolhimento e reconhecimento da diferença e da diversidade e que pode ser usado para promover saúde mental.
Construction Technology and Application of TBM in Shengli Tunnel of Tianshan Mountain under poor geological conditions

Published: September 2024

When a tunnel boring machine (TBM) excavates in poor geological conditions like fracture zones, soft rock with high ground stress, hard rock with high ground stress, and water inrush ground, severe problems such as surrounding rock collapse, convergence, rock burst and water and mud outburst are usually encountered. These problems existed in the Tianshan Shengli Tunnel project in Xinjiang, China. Several methods and techniques were adopted to reduce construction risks and improve construction efficiency. The seismic wave reflection long-distance geological forecasting method was employed to forecast and predict these adverse geological conditions. The pre-reinforcement construction method was employed on the surrounding broken rocks in front of the tunnel face to lower the risks of tunnel collapse and machine jamming. A combined steel arch was applied to prevent tunnel arch collapse. An artificial cap method was applied to prevent the jamming caused by high-ground stress soft rock. Measures such as spraying water on the tunnel face and drilling stress holes were employed to prevent rock bursts caused by high-ground stress in hard rock. Implementing the advanced pipe shed method during water influx, sudden mud, and other working conditions reduced the risk of groundwater damage to equipment and lowered risks to personnel safety. The successful application of these techniques can provide a reference for TBM tunnel construction in similar ground conditions.

Published: August 2024

Akun-akun beberapa ustadz yang aktif dalam media sosial tidak hanya menyiarkan teks agama literer, pesan dakwah yang sifatnya islami, tetapi juga menyiarkan promosi produk komersial. Penelitian ini melakukan dekonstruksi peran, fungsi, dan makna pesan dalam akun-akun ustadz di Twitter sebagai media penyiaran Islam. Selama ini penelitian tentang dekonstruksi lebih berfokus pada teks sastra. Padahal sebagai media sosial, Twitter pun menghasilkan teks yang menimbulkan konstruksi bahkan dekonstruksi. Posisi tulisan ini adalah mengkritisi media sosial sebagai media penyiaran Islam. Akun-akun ustadz @yusuf_mansyur dan @felixsiauw selain menyiarkan konten dakwah islami juga menyiarkan produk komersial milik mereka masing-masing. Akun twitter @yusuf_mansyur misalnya selain mendakwahkan sedekah, sering menyiarkan tentang Paytren yang merupakan aplikasi pembayaran berbagai tagihan. Bahkan ustadz Yusuf Mansyur pernah mendapatkan bully di Twitter karena cuitannya tentang menurunkan kurs Rupiah terhadap Dolar Amerika dengan cara berdoa. Akun twitter @felixsiauw selain menyiarkan pesan-pesan puitis islami juga sering menyiarkan promosi buku karyanya. Akun @felixsiauw pun pernah membuat kontroversi dengan menyiarkan pernyataan bahwa selfie adalah dosa. Penelitian ini menghasilkan temuan pokok tentang peran, fungsi, dan makna pesan dalam media sosial sebagai media penyiaran Islam sudah bukan lagi otoritas ustadz sebagai ustadz.

The emergence and popularity of e-commerce have led to a significant shift in the way consumers purchase products and services, and Generation Z (Gen Z) are playing a key role in driving this trend. In Malaysia, the tourism industry has benefited from the growth of e-commerce platforms such as Agoda, Expedia, Klook, and Airbnb. This study examines the factors that influence zoomers' behavioural intention towards tourism e-commerce platforms in Malaysia, with a focus on trust as a moderating variable. Questionnaire data was collected from a sample of 162 university students in Sarawak, Malaysia and analysed using a partial least square structural equation modelling (PLS-SEM) approach. The estimation procedure was conducted using the WarpPLS 8.0. The findings revealed the significance of brand recognition and perceived quality in influencing zoomers’ trust, attitude, and intention to purchase through tourism e-commerce platforms. The positive moderating role of trust was also identified. These findings are essential for tourism practitioners to better understand the needs and wants of young e-customers. The study's insights are particularly aligned with and meaningful for Sarawak's digital economy initiatives.

Background: Diabetes Mellitus is a disease characterized by hyperglycemia in a long time can cause the damage of pancreatic beta cells. Morinda citrifolia contains xeronine that can regenerate damaged pancreatic beta cells. While Curcuma longa contains curcumin which acts as an antioxidant will stabilize free radicals so it can inhibit pancreatic beta cell damage and stimulate insulin secretion.Methods: The study aim to analyze the effect of a combination of Morinda Citrifolia and Curcuma Longa in reducing blood glucose levels, increasing body weight and pancreatic histopathology in hyperglycemic mice. This type of research is an experiment with the Post Test Only Control Group. A total of  25 mice were divided into 5 groups namely PI (250 mg/dL), PII (500 mg/dL), PIII (750 mg/dL), K(+), and K(-). Blood glucose level was observed for 21 days followed by observation of pancreatic histopathology.Result: The results showed the percentage of glucose blood reduction occurred in the PI group (56.11%) and significantly different from negative controls (35.05%). There was no difference in body weight (p=0.7) and number of langerhans islet (p=0.360) in all treatment groups. The diameter of the Langerhans islet of the PI group (200.8 μm) was significantly different from the negative control (114.8 μm). (p<0.05Conclusion : The combination of Morinda citrifolia and Curcuma longa extract can reduce blood glucose levels and increase body weight but not be able to optimally repair pancreatic islet damage.

The Influence of Parental Role on Adolescent Sexual Behaviour and HIV/AIDS in KwaZulu-Natal, South Africa.
Authors: Ringisai Lovemore
Published: September 2024

Background: HIV/AIDS risky behaviour remains a critical health concern for adolescents, specifically at high school level. In South Africa, the rapid increase of risky lifestyles and sexual behaviours among adolescents could be mainly attributed to poor parental skills and broken family structures. Four identified sexual risk behaviours that are of concern in South Africa are age at sexual debut, multiple sexual partners, condom use and transactional sex.Methods:  Data was collected using a quantitative cross-sectional survey with samle consist with 450 male and female high school adolescents between 14 to 18 years from 3 different South African school settings. Collected data was analyzed using SPSS descriptive statistics procedure.Result: 79.7% of the respondents had only one parent still alive with 4.9 % of the respondents indicated to have lost both parents. Only 13.5% of the respondents were from a nuclear family. The majority of the respondents were (41.2%) living with grandparents. This high level of family disintegration, parental absence and  poor parenting skills in South Africa exposed 73.3% (330) of the respondents to early sexual debut, transactional sex, unprotected sex and having multiple sexual partners. The study proved that there is a statistical association between guardianship and age at sexual debut; guardianship and multiple sexual partners; guardianship and condom use; guardianship and transactional sex.Conclusion : The revealed significant high risk sexual behaviour among adolescents in KwaZulu-Natal should inform Health and educational authorities     to utilize these key findings to design more effective local strategies to train and assist parents and caregivers on parenting skills
“As a Muslim…”: on the importance of intercultural responsibility in transnational cultural exchanges
Authors: Nattheeraphong Anyarat , Jenks Christopher
Published: September 2024

Cultural exchange is increasingly becoming an essential activity of higher education as the world continues to experience widespread ethnocentrism because of war, migration, political provocation, and nationalism. Research in areas related to cultural exchange have also increased with the rise of teacher and student mobility, leading to an exciting body of scholarship. Several aspects of intercultural communication, however, remain under-researched in the study of cultural exchange. One such example is intercultural responsibility. The current study adds to this body of work by investigating how Muslim students that were part of a cultural exchange program in Thailand used notions of intercultural responsibility to make sense of their encounters and identities. The findings show that national and religious identities are both barriers to, and resources for, intercultural communication in general, and the social practices of Muslim students in particular. Intercultural responsibility is important to scholars and educators, as it can empower students to become agentive in their participation in intercultural communication, allowing them to reflect on and utilize their linguistic, cultural, and historical repertoire when interacting with individuals and communities that do not share their same cultural traditions and practices.
Dialektwandel als Systemwandel: Die Genuskongruenz bei den Numeralien

zwei und

drei in den deutschen Dialekten und darüber hinaus
Authors: Pheiff Jeffrey
Published: September 2024

This paper investigates the gender agreement behavior of the cardinal numbers two and three in various German(ic) dialects in attributive function using a corpus of dialect grammars and linguistic atlases. In contrast to previous studies which have investigated certain regions, this paper focuses the entire German-speaking area. The results show diatopic differences in gender agreement depending on the numeral as well as certain tendencies in its development through a comparison of the two datasets. The paper closes with a discussion of the differences between the standard language and the dialects, and proposes that the loss of gender agreement was set in motion by dialect sound mergers.

Published: September 2024

Objectives

The objective of this study is to evaluate the analytical and diagnostic performance of a high-sensitivity point-of-care (POC) cardiac troponin I assay, the Quidel TriageTrue™ (QuidelOrtho Inc, San Diego, USA), compared to central laboratory testing (CLT) in accelerated diagnostic protocols (ADP) in real time in a clinical environment.

Methods

In a nested sub-study of a pragmatic randomised control trial, consecutive patients with suspected acute coronary syndrome (ACS) and chest pain <12 h duration were randomised to the ESC 0/1 and 0/3-h ADP. Subjects underwent sampling for Quidel TriageTrue POC hs-TnI whole blood and plasma, CLT hs-TnT Roche Elecsys and a validated, NICE approved CLT High sensitivity cardiac troponin I (hs-TnI) (Siemens Attellica) at each time point. Assay imprecision was assessed by repeat analysis of whole blood samples at three levels (low, near 10 % CV 5–10 ng/L, medium, approximating 99th percentile 15–25 ng/L and high, 3–5 times the 99th percentile, 60–100 ng/L). Final diagnosis was adjudicated at 6 weeks by Roche hs-TnT using the 4th universal definition of myocardial infarction (MI).

Results

A total of 1,157 patients consented and had both investigational POC whole blood and plasma and central lab hs-cTn available. The median age was 59, 47.2 % were female and 15 % had suffered a previous MI. Assay imprecision of whole blood POC TriageTrue revealed 10 % CV at 8.6 ng/L (>50 % lower than 99th percentile [20.5 ng/L]) and a 20 % CV at 1.2 ng/L. Receiver operator characteristics (ROC) curves were computed for each assay against adjudicated index type 1 MI to study clinical performance. At all-time points there were excellent performance for whole blood POC TriageTrue: area under the curve (AUC) 0.97 [95 % CI 0.94–098], 0.98 [95 % CI 0.97–1.00] and 0.95 [95 % CI 0.92–0.98] at time 0, 1 and 3 h respectively. There was statistical equivalence for performance of whole blood and plasma POC TriageTrue hs-TnI and laboratory Siemens Atellica hs-TnI.

Conclusions

The whole blood POC TriageTrue hs-TnI assay demonstrates imprecision levels consistent with high sensitivity characteristics and has a clinical performance equivalent to an established, validated and NICE approved laboratory Siemens Atellica hs-TnI.

Objectives

This study aimed to assess the validity of external quality assessment (EQA) laboratory results across various cultural and environmental contexts and to identify potential improvement areas.

Methods

The International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) Task Force on Global Laboratory Quality (TF-GLQ) conducted a 2-year study (2022 and 2023) in which EQA materials, related software and online training was provided by a commercial vendor to 100 laboratories in ten IFCC member society countries. The results were analysed on a monthly basis by the TF-GLQ, to show the number of submissions per country, tests per lab, acceptability rates, random failures and to get a measure of which analytes performed poorly.

Results

The EQA material was dispatched on a quarterly basis. Some countries had problems with customs releasing the material in a timely manner, resulting in laboratories not receiving them on time leading to no submission. We report here the results for the second year of the survey. The number of examinations varied between laboratories, ranging from seven to 84 analytes. Of the ten countries surveyed, six averaged greater than 90 % acceptable results over the whole 12-months cycle, one had unacceptable results for two of the nine months they returned results and the other four were considered to not perform to an acceptable standard.

Conclusions

All 100 participating laboratories indicated satisfaction with the EQA survey and related services, including on-site training, and report handling. However, specimen receiving issues, suggest benefits in dispatching materials for a full 12-month cycle. Significant discrepancies in EQA performance indicate that four countries require long-term assistance, training and guidance. To ensure reliable patient results, promoting EQA in certain countries is essential to achieve the required level of quality.
