High-quality on-chip entangled photon source with broad tunable range based on coupling compensation
Authors: Fan Pengtao , Wang Xilan , Hao Ran 
Published: May 2024

This paper introduces a tunable and high-quality photon source that utilizes evanescent-wave coupling phase matching. By adjusting the coupling gap, the signal light can be tuned from 1307 nm to 1493.9 nm, and the idler light can be tuned from 1612.8 nm to 1907 nm. Throughout the entire tuning range, the purity of the photon pairs remains above 92%. In specific tuning ranges (signal photons from 1307 nm to 1421.7 nm and idler photons from 1706.4 nm to 1907 nm), the purity exceeds 99% and the full width at half-maximum of the generated photon spectra is less than 1.85 nm. The photon source is designed using a silicon–organic hybrid waveguide, which effectively minimizes the impact of two-photon absorption and achieves a 15 dB enhancement in four-wave mixing conversion efficiency compared to a strip waveguide. This design may promote efficient and precise generation of high-quality photons at desired frequencies, offering promising potential for various applications in quantum technologies.

Published: May 2024

Broadband quantum light is a vital resource for quantum metrology and spectroscopy applications such as quantum optical coherence tomography or entangled two photon absorption. For entangled two photon absorption in particular, very high photon flux combined with high time-frequency entanglement is crucial for observing a signal. So far these conditions could be met by using high power lasers driving degenerate, type 0 bulk-crystal spontaneous parametric down conversion (SPDC) sources. This naturally limits the available wavelength ranges and precludes deterministic splitting of the generated output photons. In this work we demonstrate an integrated two-colour SPDC source utilising a group-velocity matched lithium niobate waveguide, reaching both exceptional brightness 1.52⋅106pairssmWGHz and large bandwidth (7.8 THz FWHM) while pumped with a few mW of continuous wave (CW) laser light. By converting a narrow band pump to broadband pulses the created photon pairs show correlation times of Δτ ≈ 120 fs while maintaining the narrow bandwidth Δω
p
≪ 1 MHz of the CW pump light, yielding strong time-frequency entanglement. Furthermore our process can be adapted to a wide range of central wavelengths.

Published: May 2024

Molecular diagnostics are a primary tool of modern chemistry, enabling
researchers to map chemical reaction pathways and rates to better
design and control chemical systems. Many chemical reactions are
complex, involving multiple species and reaction pathways occurring on
µs or shorter timescales. Existing diagnostic approaches provide a
subset of chemical and thermodynamic information. Here we optimize
across many diagnostic objectives by introducing a high-speed and
broadband, mid-infrared dual-frequency-comb absorption spectrometer.
The optical bandwidth of >1000cm−1 covers absorption fingerprints of
many species with spectral resolution <0.03cm−1 to accurately discern their absolute
quantities. Key to this advance are 1 GHz pulse repetition rate
mode-locked frequency combs covering the 3–5 µm region that enable a
spectral acquisition rate of 290cm−1 per 17.5 µs per detector for in situ tracking of fast chemical process
dynamics. We demonstrate this system to quantify the abundances and
temperatures of each species in the complete reactants-to-products
breakdown of 1,3,5-trioxane, which exhibits a formaldehyde
decomposition pathway that is critical to modern low-temperature
combustion systems. By maximizing the number of observed species and
improving the accuracy of temperature and concentration measurements,
this spectrometer provides a pathway for modern chemistry approaches
such as combining chemical models with machine learning to constrain
or predict complex reaction mechanisms and rates.
Perceptions of yellow fever emergency mass vaccinations among vulnerable groups in Uganda: A qualitative study
Authors: Huebl Lena , Nnyombi Aloysious , Kihumuro Aban , Lukwago Denis , Walakira Eddy , Kutalek Ruth 
Published: May 2024

Background
Yellow fever (YF), a mosquito-borne viral hemorrhagic fever, is endemic in Uganda and causes frequent outbreaks. A total of 1.6 million people were vaccinated during emergency mass immunization campaigns in 2011 and 2016. This study explored local perceptions of YF emergency mass immunization among vulnerable groups to inform future vaccination campaigns.

Methodology
In this qualitative study, we conducted 43 semi-structured interviews, 4 focus group discussions, and 10 expert interviews with 76 participants. Data were collected in six affected districts with emergency mass vaccination. We included vulnerable groups (people ≥ 65 years and pregnant women) who are typically excluded from YF vaccination except during mass immunization. Data analysis was conducted using grounded theory. Inductive coding was utilized, progressing through open, axial, and selective coding.

Principal findings
Participants relied on community sources for information about the YF mass vaccination. Information was disseminated door-to-door, in community spaces, during religious gatherings, and on the radio. However, most respondents had no knowledge of the vaccine, and it was unclear to them whether a booster dose was required. In addition, the simultaneous presidential election during the mass vaccination campaign led to suspicion and resistance to vaccination. The lack of reliable and trustworthy information and the politicization of vaccination campaigns reinforced mistrust of YF vaccines.

Conclusions/significance
People in remote areas affected by YF outbreaks rely on community sources of information. We therefore recommend improving health education, communication, and engagement through respected and trusted community members. Vaccination campaigns can never be seen as detached from political systems and power relations.
Association between executive functions and COMT Val108/158Met polymorphism among healthy younger and older adults: A preliminary study
Authors: Apa Zoltan , Gilsoul Jessica , Dideberg Vinciane , Collette Fabienne 
Published: May 2024

Background and objectives
Genetic variability in the dopaminergic system could contribute to age-related impairments in executive control. In this study, we examined whether genetic polymorphism for catechol-O-methyltransferase (COMT Val158Met) is related to performance on updating, shifting and inhibition tasks.

Methods
We administered a battery of executive tasks assessing updating, shifting and inhibition functions to 45 older and 55 younger healthy participants, and created composite z-scores associated to each function. Six groups were created based on genetic alleles (Val/Val, Val/Met, Met/Met) derived from the COMT gene and age (younger, older). Age and genotype effects were assessed with t-test and ANOVA (p<0.05).

Results
A lower performance was observed in the older group for the three executive processes, and more particularly for inhibition. Moreover, older participants homozygous for the Val allele have a lower performance on the inhibition composite in comparison to younger Val/Val.

Conclusions
These results confirm presence of executive performance decrease in healthy aging. With regard to genetic effect, older participants seem particularly disadvantaged when they have a lower baseline dopamine level (i.e., Val/Val homozygous) that is magnified by aging, and when the executive measure emphasize the need of stable representations (as in inhibition task requiring to maintain active the instruction to not perform an automated process).

Published: May 2024

Introduction
Studies indicate that individuals with chronic conditions and specific baseline characteristics may not mount a robust humoral antibody response to SARS-CoV-2 vaccines. In this paper, we used data from the Texas Coronavirus Antibody REsponse Survey (Texas CARES), a longitudinal state-wide seroprevalence program that has enrolled more than 90,000 participants, to evaluate the role of chronic diseases as the potential risk factors of non-response to SARS-CoV-2 vaccines in a large epidemiologic cohort.

Methods
A participant needed to complete an online survey and a blood draw to test for SARS-CoV-2 circulating plasma antibodies at four-time points spaced at least three months apart. Chronic disease predictors of vaccine non-response are evaluated using logistic regression with non-response as the outcome and each chronic disease + age as the predictors.

Results
As of April 24, 2023, 18,240 participants met the inclusion criteria; 0.58% (N = 105) of these are non-responders. Adjusting for age, our results show that participants with self-reported immunocompromised status, kidney disease, cancer, and “other” non-specified comorbidity were 15.43, 5.11, 2.59, and 3.13 times more likely to fail to mount a complete response to a vaccine, respectively. Furthermore, having two or more chronic diseases doubled the prevalence of non-response.

Conclusion
Consistent with smaller targeted studies, a large epidemiologic cohort bears the same conclusion and demonstrates immunocompromised, cancer, kidney disease, and the number of diseases are associated with vaccine non-response. This study suggests that those individuals, with chronic diseases with the potential to affect their immune system response, may need increased doses or repeated doses of COVID-19 vaccines to develop a protective antibody level.
Systematic evaluation of integration between China’s digital economy and sports industry: Two-stage grey relational analysis and vector autoregressive model
Authors: Sun Xu , Su Lide , Zhou Bo , Bu Te , Zhang Yang 
Published: May 2024

Objectives
The development of the digital economy constitutes a key component of China’s endeavors to advance towards “Digital China.” The sports industry functions as a new catalyst for high-quality economic growth. This study systematically evaluated the integration between these two sectors.

Methods
First, we conducted two levels of grey relational analysis to assess their integration between 2016 and 2021. Second, we conducted a VAR analysis to determine whether their integration between 2009 and 2021 represents a causal relationship.

Results
At the macro level, the grey relational analysis reveals that the sports industry (grade = 0.770) ranked second among China’s eight key economic sectors in terms of digital economy integration. At the meso level, a wide variation (ranging from 0.606 to 0.789) existed in the grade of integration between the digital economy and the sub-sectors of the sports industry. According to the VAR model, the digital economy does not Granger cause (p = 0.344) the growth of the sports industry.

Conclusions
This study yielded two added values to the existing literature: First, there exists a sectoral imbalance in the digitization process; second, the explosive growth of the sports industry was not primarily caused by the digital economy. Accordingly, the “sports + digital” complex is still in the first wave of technological integration. We propose three policy recommendations, namely, sectoral synergistic development, overtaking via esports IP, and new economy and new regulation. Collectively, these findings provide updated insights for the digital transformation towards “building a leading sports nation” and “Digital China.”
Validation of a Primary Biliary Cholangitis–Specific Version of Chronic Liver Disease Questionnaire: CLDQ-PBC
Authors: Younossi Zobair M. , Stepanova Maria , Younossi Issah , Racila Andrei 
Published: May 2024

INTRODUCTION:
Primary biliary cholangitis (PBC) is a chronic liver disease, leading to cirrhosis and impairment of patient-reported outcomes. We aimed to develop a PBC-specific version of the Chronic Liver Disease Questionnaire (CLDQ) instrument to assess health-related quality of life of patients with PBC.

METHODS:
From our Liver Database, we included patients with PBC who had CLDQ, clinicolaboratory data, and completed Short Form-36 and The Functional Assessment of Chronic Illness Therapy—Fatigue. The 29 items of CLDQ were subjected to item reduction, exploratory factor analysis, and fed into a standard instrument validation pipeline.

RESULTS:
Data were available for 108 patients with PBC: 57 ± 11 years, 7% male, 58% cirrhosis, and 24% decompensated cirrhosis (Child B and C). Of 29 CLDQ items, none met the exclusion criteria. Exploratory factor analysis (95% of variance) returned 7 factors. Based on evaluation of factor loadings and face validity, those factors yielded 7 domains (Diet, Emotion, Fatigue, Itch, Symptoms, Sleep, and Worry). Good to excellent internal consistency (Cronbach's α 0.85–0.93) was observed for 5/7 domains. For the remaining 2 domains (Diet and Itch), additional items obtained from patients, experts, and review of the literature were included. For 5 domains, known-group validity tests discriminated between patients with PBC with and without cirrhosis, advanced cirrhosis, and depression (P < 0.05 for 3–5 domains). The CLDQ-PBC domains were correlated with relevant domains of Short Form-36, CLDQ-PBC Fatigue correlated with Fatigue Scale of Functional Assessment of Chronic Illness Therapy—Fatigue (rho = +0.85), and CLDQ-PBC Worry domain negatively correlated with alkaline phosphatase (rho = −0.38, P = 0.0082).

DISCUSSION:
The CLDQ-PBC has been developed based on the original CLDQ. The new instrument has evidence for internal consistency and validity and is being fully validated using an external cohort.

Published: May 2024

This paper suggests a model of information and technological support for inclusive education that considers the specifics of this process in Ukraine. Inclusive education is a key factor in the development of civic democracy. It aims to transform schools into platforms of equality and improvement for all students. The literature review aims to assess the current state of inclusive education and identify the conditions necessary for developing inclusive education systems. The article explores the following aspects: the concept of inclusive education as a platform for civic democracy; the influence of historical context and societal values on attitudes toward differences and disabilities; research covers the current state of inclusive education in Ukraine, America, and Europe; it describes the obstacles that preceded the implementation of inclusive education in these countries. As part of this model, the authors consider a data storage system designed for the comprehensive processing of information related to the psychophysical assessment of people with special needs. The article provides an overview of key aspects and formalized criteria for assessing the impact of implementing information technologies on the outcomes of inclusive educational support. These criteria consider social and scientific-technical aspects of implementing information technologies at every stage of inclusive education support. The results of the study indicate that most data focus on the analysis of attitudes toward inclusive education and people with disabilities. Although most survey participants generally support inclusive educational initiatives. In addition, the authors identified a series of obstacles that must be overcome to implement these initiatives in the region successfully. The article identifies the possibilities of implementing inclusive education in the historical context of the region. Moreover, the authors identified structural and cultural barriers to its implementation and provided directions towards future research.
Komiksowy rekwizyt i jego specyfika w „Trasie promocyjnej” Andiego Watsona
Authors: Kowalczyk Marcin 
Published: May 2024

In comics, similar to theatre or film, props play a crucial role in storytelling. However, in the comic medium, the function of a prop as a meaningful element takes on a distinct character. Cartoons not only depict objects but also give them specific significance through artistic representation. The article aims to explore this phenomenon by examining the graphic novel The Book Tour by Andi Watson. The analysis draws upon the insights of renowned comics scholars but also refers to broader conceptual frameworks. Thus additional links to theoretical proposals on the semiotics of visual representations and semiotics of the stage. Throughout the discussion, the paper presents artistic techniques used by Andi Watson that contribute to the unique nature and the way of functioning of comic props.

Abstract

Objectives
Heparin is a highly charged polysaccharide used as an anticoagulant to prevent blood coagulation in patients with presumed myocardial infarction and to prepare heparin plasma samples for laboratory tests. There are conflicting data regarding the effects of heparin on the measurement of cardiac isoforms of troponin I (cTnI) and troponin T (cTnT), which are used for the immunodiagnosis of acute myocardial infarction. In this study, we investigated the influence of heparin on the immunodetection of human cardiac troponins.

Methods
Gel filtration (GF) techniques and sandwich fluoroimmunoassay were performed. The regions of сTnI and cTnT that are affected by heparin were investigated with a panel of anti-cTnI and anti-cTnT monoclonal antibodies, specific to different epitopes.

Results
Heparin was shown to bind to the human cardiac full-size ternary troponin complex (ITC-complex) and free cTnT, which increased their apparent molecular weights in GF studies. Heparin did not bind to the low molecular weight ITC-complex and to binary cTnI-troponin С complex. We did not detect any sites on cTnI in the ITC-complex that were specifically affected by heparin. In contrast, cTnT regions limited to approximately 69–99, 119–138 and 145–164 amino acid residues (aar) in the ITC-complex and a region that lies approximately between 236 and 255 aar of free cTnT were prone to heparin influence.

Conclusions
Heparin binds to the ITC-complex via cTnT, interacting with several sites on the N-terminal and/or central parts of the cTnT molecule, which might influence the immunodetection of analytes in human blood.
A system mapping activity to visualize lithium’s interconnectedness to societal and environmental aspects of the green energy transition

Published: May 2024

Abstract
Lithium’s role in the global green energy transition provides an engaging context to visualize the interconnectedness of chemistry to seismic shifts taking place in society. Lithium has seen a dramatic increase in utilization, but given lithium’s current low rates of recyclability, this development is exacerbating the e-waste problem. Equally important, we posit that lithium extraction, from either brine or ore, and the associated impacts on the environment and local communities should not be so easily decoupled from the shift in human behaviors causing its demand. Presented here is a mapping activity that was trialed in professional learning workshops organized in New Zealand for secondary/high school chemistry teachers. In their mapping activity response, the teachers were able to connect typical school chemistry content (batteries, chemical processes) with environmental (planetary systems) and social, economic, and ethical considerations (useful products, unintended consequences, inequity in access to water) of the ongoing electrification of society. The teachers indicated a positive intention to utilize the activity, or one similar with a different chemical process or product, in their own classrooms. A school-ready version of the activity is provided in the supplementary information, which was revised based on feedback from the teachers attending the workshops.
