AbstractA quantum channel is a physical media able to carry quantum signals. Quantum key distribution (QKD) requires direct quantum channels between every pair of prepare-and-measure modules. This requirement heavily compromises the scalability of networks of directly connected QKD modules. A way to avoid this problem is to introduce switches that can dynamically reconfigure the set of connections. The reconfiguration of a quantum channel implies that the modules using it can adapt to the new channel and peer.The maturity and flexibility of continuous-variable QKD (CV-QKD) qualifies it as a strong contender for integration into optical communication networks. Here we present the implementation of a switched CV-QKD network embedded in the Madrid quantum testbed. The optical switching of the quantum paths significantly reduces the amount of required QKD modules and facilitates the scalability of the network. This demonstration highlights the flexibility and ease of integration of this emerging technology.

BACKGROUND:
Abnormal atrial potentials (AAPs) recorded during sinus rhythm/atrial pacing may indicate areas of slow conduction capable of supporting reentrant atrial tachycardia (AT). Therefore, we sought to examine the relationship between AAPs and AT circuits.

METHODS:
One hundred twenty-three reentrant ATs in 104 patients were analyzed. AAPs, consisting of fragmented potentials and split potentials, were assessed using the Rhythmia LUMIPOINT algorithm.

RESULTS:

There was 93±13% overlap between areas with AAPs during sinus rhythm/atrial pacing and areas of slow conduction along the reentry circuit during AT. The cumulative area of AAPs was smaller in patients with localized-reentrant ATs compared with anatomic macro-reentrant ATs (20.0 [14.6–30.5] versus 28.9 [21.8–35.6] cm
2
;
P
=0.021). Patients with perimitral ATs had larger areas of AAPs on the lateral wall whereas patients with roof-dependent ATs had larger areas of AAPs on the roof and posterior wall (
P
≤0.018 for all comparisons). The patchy scar that was associated with localized-reentrant AT exhibited a larger area of AAPs at its periphery than the scar that did not participate in localized-reentrant AT (3.1 [2.4–4.5] versus 1.0 [0.7–1.6] cm
2
;
P
<0.001).

CONCLUSIONS:
AAPs recorded during sinus rhythm/atrial pacing are associated with areas of slow conduction during reentrant AT. The burden and distribution of AAPs may provide actionable insights into AT circuit features, including in cases in which ATs are difficult to map.
Broodthaers's Debt
Authors: Stark Trevor 
Published: September 2023

Abstract
This essay investigates the status of “reification” in the work of Marcel Broodthaers, particularly in the 1971 “Section Financière” of his Musée d'Art Moderne, Départment des Aigles. It will pose finance and debt as social forms through which Broodthaers both experienced reification concretely and attempted to register its forming pressure upon the artwork's conditions of possibility. The article argues that it was Broodthaers's understanding of reification that allowed him, at a crux in the history of finance represented by the end of the Bretton Woods agreement in 1971, to posit art as a speculative investment at once uncoupled from the concrete limitations of production and ever-more-tightly ensnared by the economic power of debt.
Printing Islamic Modernism: Arabic Texts for Arab and South Asian Muslims in the Early Twentieth Century
Authors: Bar Sadeh Roy 
Published: September 2023

Abstract
This article examines the relationship between Islamic modernism and Arabic print between the Mashriq and Indian subcontinent in the early twentieth century. Seeking to understand how Islamic modernists modified their message as they targeted new audiences, even as they promoted a unilingual program, this article explores the two printed publications in Arabic that emerged from the 1912 journey of Muhammad Rashid Rida (1865–1935), the founder of the Cairo-based journal al-Manar (The Lighthouse, 1898–1935), to British India. The first publication is “ʿUjala min rihlat al-Hind” (A Brief Report from the Journey to India), which Rida serially published in Cairo in 1912. The second publication is the summary of Rida’s subcontinental travels by his Iraqi-born Urdu translator, Sayyid ʿAbd al-Haqq Haqqi al-Aʿzami al-Baghdadi al-Azhari (1873–1924), which he wrote in the United Provinces town of Aligarh during 1912. Examining these two texts together, this article argues that their publication reflected the two separate concerns of their authors. While Rida sought to convey to al-Manar’s readership his experiences in British India by depicting them as analogous to the realities of the Ottoman Arab provinces and Egypt, al-Azhari sought to integrate al-Manar’s Islamic modernist enterprise into North Indian spheres of Islamic thought, practice, and print aesthetics. In so doing, this article shows how different audiences and modes of circulation enabled Islamic modernist enterprises to operate on both regional and transregional scales, reflecting the malleability of, and interconnectedness between, the worlds of Arabic and Urdu print during the period in question.

Abstract
Atmospheric aerosol and chemistry modules are key elements in Earth system models (ESMs), as they predict air pollutant concentrations and properties that can impact human health, weather, and climate. The current uncertainty in climate projections is partly due to the inaccurate representation of aerosol direct and indirect forcing. Aerosol/chemistry parameterizations used within ESMs and other atmospheric models span large structural and parameter uncertainties that are difficult to assess independently of their host models. Moreover, there is a strong need for a standardized interface between aerosol/chemistry modules and the host model to facilitate portability of aerosol/chemistry parameterizations from one model to another, allowing not only a comparison between different parameterizations within the same modeling framework, but also quantifying the impact of different model frameworks on aerosol/chemistry predictions. To address this need, we have initiated a new community effort to coordinate the construction of a Generalized Aerosol/Chemistry Interface (GIANT) for use across weather and climate models. We aim to organize a series of community workshops and hackathons to design and build GIANT, which will serve as the interface between a range of aerosol/chemistry modules and the physics and dynamics components of atmospheric host models. GIANT will leverage ongoing efforts at the U.S. modeling centers focused on building next-generation ESMs and the international AeroCom initiative to implement this common aerosol/chemistry interface. GIANT will create transformative opportunities for scientists and students to conduct innovative research to better characterize structural and parametric uncertainties in aerosol/chemistry modules, and to develop a common set of aerosol/chemistry parameterizations.
Lagrangian Simulations of Moisture Sources for Northeast China Precipitation during 1979–2018
Authors: Yao Shibo , Jiang Dabang 
Published: September 2023

Abstract
In this study, the Flexible Particle Dispersion Model (FLEXPART) is applied to analyze the moisture sources of Northeast China precipitation from March 1979 to February 2018. The results show that there is mainly one particle aggregation channel in winter, namely the eastern Europe–Siberia–Lake Baikal–Northeast Asia channel (the western channel). In comparison with winter, there are two extra channels in summer, namely the Indochina Peninsula–South China Sea–East China channel (the southern channel) and the Philippine Sea–Ryukyu Islands channel (the southeastern channel). From the long-term mean, the Siberia–Mongolia–Xinjiang region (SMX) is the most dominant moisture source of Northeast China precipitation in all seasons. As for the moisture contribution rate of each source region to Northeast China precipitation, there is a seesaw interannual relationship between SMX and other source regions. The moisture from Central and East China is critical to the interdecadal shift of Northeast China summer precipitation. This interdecadal shift is related to the moisture transport from low latitudes to Northeast China, which is modulated by the positive phase of the Pacific decadal oscillation and the negative phase of the Atlantic multidecadal oscillation.
Reflection and Scattering of Low-Mode Internal Tides on the Continental Slope of the South China Sea
Authors: Li Wei , Xie Xiaohui 
Published: September 2023

Abstract
It is well known that strong low-mode internal tides generated in Luzon Strait propagate westward to impinge continental slopes in the northeastern South China Sea (SCS). The reflection and scattering of these internal tides including diurnal and semidiurnal components on the slopes are quantitatively investigated using two sets of mooring data and a linear internal tide model with realistic topography and stratification. Flux reflections computed from mooring data collected on the continental slopes are consistent with the linear model. Based on the results of the observations and simulations, a map of low-mode internal tide reflection and scattering coefficients along the continental margin in the northeastern SCS is revealed. On average, diurnal internal tides lose 38% of their energy to high modes (≥mode 4) that are assumed to dissipate on the slopes, transmit 28% onto the continental shelf, and reflect 31% back to the deep ocean. On the contrary, most of the semidiurnal energy (89%) transmits onto the continental shelf, and only 11% is scattered to high modes (7%) and reflected back to the deep ocean (4%). For diurnal internal tides, a large fraction of energy that is scattered to high modes and reflected back to the deep sea can be attributed to the critical–supercritical slopes, while the weak reflection for the semidiurnal energy is due to the subcritical slopes. These quantitative descriptions for evolutions of low-mode internal tides incident to the slopes provide an energy budget map on the continental slopes in the northeastern SCS.

Background Current evidence regarding gender difference in retroperitoneal liposarcoma (RLPS) is scarce, so we sought to investigate whether gender may affect prognosis after primary resection of RLPS. Methods We used the Surveillance, Epidemiology, and End Results (SEER) database to identify RLPS patients from January 1973 to December 2015. Multivariate cox proportional hazard analysis was adopted to generate adjusted hazard ratio (AHR) and 95% confidence intervals (CIs) of survival outcomes. Results In total, 2108 RLPS patients, including 971 women and 1137 men, were identified, with a median follow-up of 45.0 (17.0-92.0) months. The 5-year and 10-year overall survival rates were 50.5% and 31.5% for men and 60.4% and 42.5% for women. The 5-year and 10-year disease-specific survival rates for men and women were 71.5%, 57.3% and 76.3%, 62.1%, respectively. We found men were associated with an increased risk of all-cause mortality (AHR 1.3, 95% CI 1.0-1.6, P = .017) but not disease-specific mortality (AHR 1.2, 95% CI .9-1.6, P = .246). The subgroup analyses revealed that men were associated with an increased risk of all-cause mortality in patients with low-grade tumors (AHR 1.8, 95% CI 1.3-2.5) or patients who received non-radical resection (AHR 1.6, 95% CI 1.2-2.1). In the subgroup of low-grade tumors, men were also associated with an increased risk of disease-specific mortality (AHR 2.0, 95% CI 1.2-3.3). Conclusion Men may have worse survival after primary resection of RLPS compared with women, especially in patients with low-grade tumors or patients who received non-radical resection. Gender-based disparities may deserve more attention in patients with RLPS.

Background Ovarian cancer is one of the deadliest cancers in women. Improved preventative, diagnostic, and therapeutic strategies are needed. Certain dietary patterns and nutrients such as vitamin D and omega-3 fatty acids are associated with reduced cancer risk, but their effects on ovarian cancer remain to be fully elucidated, and their combined effects have not been explored. Aim To determine the individual and combined effects of the active vitamin D metabolite, calcitriol, and the omega-3 fatty acid, docosahexaenoic acid, on cell growth, and the abundance of the vitamin D receptor (VDR), proteins that modulate cell cycle progression, and apoptotic markers. Methods OVCAR4 cells, a model of ovarian cancer, were treated with calcitriol, and docosahexaenoic acid, either alone or in combination. Effects on cell growth were determined by the sulforhodamine B assay. Changes in VDR, the cell cycle promotor c-Myc, the cell cycle inhibitor p27 and cleaved PARP, were determined by Western blotting. Results While OVCAR4 cell growth was inhibited by individual treatment with either calcitriol or docosahexaenoic acid, the combined treatment revealed enhanced growth inhibition as compared to either treatment alone. Furthermore, long-term treatment (12 days) yielded stronger growth inhibition at lower concentrations as compared to short-term treatments (3 days). Accompanying this growth inhibition was a decrease in c-Myc, and an increase in p27. Conclusions The observed reduction in cell growth mediated by calcitriol and docosahexaenoic acid highlights the need for further research utilizing these nutrients, alone and especially in combination, to support ovarian cancer prevention and treatment.

Published: September 2023

Background: Cross-sectional surveys using the Standardized Monitoring and Assessment of Relief and Transitions methodology have been conducted annually in Chad since 2015 to evaluate population-level nutritional status. Objective: This analysis characterizes national and subnational trends in child wasting and women’s thinness from 2015 to 2021 in Chad and identifies risk factors during the COVID-19 pandemic. Methods: Annual survey data with 12,000 to 15,000 households were included. Wasting was estimated for children 6 to 59 months using the WHO child growth standards, and among women 15 to 49 years, thinness was defined as mid-upper arm circumference <23 cm. Trends were stratified by agroecological zone, and chi-square tests used to assess statistical significance. Simple and multivariate logistic regression models were conducted for 2020 and 2021 to identify risk factors of wasting and thinness. Results: About 11,958 to 17,897 children and 9883 to 15,535 women contributed values each year. National wasting and thinness rates did not significantly decrease over the 7-year period (wasting: 14.1% to 12.1%, P = .43; thinness: 15.2% to 13.4%, P = .51) and wasting rose from 2020 to 2021. The Saharan and Sahelian zones had consistently higher rates compared to the Sudanian zone. Younger age, male sex, inadequate infant and young child feeding practices, and poorer household socio-economic factors were associated with greater odds of child wasting. For women, younger age, lack of nutrition knowledge, and poorer household socio-economic factors increased the odds of thinness. Conclusions: Undernutrition in Chad has not improved since 2015, and the COVID-19 pandemic likely exacerbated the crisis among children nationally and among women subnationally. Multisectoral approaches and regional targeting of interventions are recommended.

Published: September 2023

Background: Outpatient methadone guidelines recommend starting at a low dose and titrating slowly. As fentanyl prevalence and opioid-related mortality increases, there is a need for individuals to rapidly achieve a therapeutic methadone dose. Hospitalization offers a monitored setting for methadone initiation, however dosing practices and safety are not well described. Methods: Retrospective, observational analysis of hospitalized patients with opioid use disorder seen by an inpatient addiction consult team in an academic medical center who were newly initiated on methadone between 2016 and 2022. We calculated initial daily dose, maximum daily dose, timing interval of dose escalation, whether patients were connected to an opioid treatment program (OTP) prior to discharge, whether adverse effects or safety events occurred during the hospitalization, and whether such events were definitely or probably related versus possibly related or unrelated to methadone. Results: One hundred twelve patients were included. The mean initial daily methadone dose administered was 32 mg (range: 10-90 mg). The mean maximum dose reached was 76.8 mg (range 30-165 mg). The mean number of days from initial to peak dose was 5.6 days (range 1-19 days). Overall, 30% of patients experienced a safety event, most commonly sedation. Only 4 safety events were deemed probably or definitely related to methadone. In regression analyses, there was no significant difference between starting doses among patients with or without sedation but there was a relationship between last dose and the likelihood of any possibly related event, with those ending at a dose of 100 mg or higher having a higher likelihood event, compared to those ending at lower doses (47.8% vs 12.4%, P < .001). Seventy-six percent were connected to OTP before discharge. Conclusion: Among hospitalized patients initiating methadone, rapid dose titration was infrequently associated with related safety events and most were connected to community-based methadone treatment before discharge.

Published: September 2023

Background: Since 2019, the United States (US) has witnessed an unprecedented increase in drug overdose and alcohol-related deaths. Despite this rise in morbidity and mortality, treatment rates for substance use disorder remain inadequate. Insufficient training in addiction along with a dearth of addiction providers are key barriers to addressing the current addiction epidemic. Addiction-related clinical experiences can improve trainee knowledge, yet they remain dependent on practice sites and residency training environments. Asynchronous learning, in the form of video-based modules, may serve as a complement to formal, scheduled lectures and clinical experiences. Objectives To evaluate the educational impact of a video-based addiction curriculum in 2 residency programs at a large safety net academic medical center with a high volume of patients with substance use disorders. Methods Family Medicine (FM) and Internal Medicine (IM) residency interns (PGY1s) (n = 60) had access to 28 minutes of video content related to opioid use disorder (OUD) and alcohol use disorder (AUD) during the first 2 months of their residency training. Interns were asked to complete voluntary and anonymized pre- and post-surveys in Qualtrics that included knowledge and confidence-based questions about the management of OUD and AUD, in addition to questions about prior exposure to and future interests in addiction training and practice. Data were analyzed with non-parametric sign tests. Results Twenty-eight interns completed both OUD pre- and post-surveys, and 24 interns completed all AUD survey questions. There was a statistically significant increase in the number of interns who reported increased knowledge of and confidence around diagnosis, management, and ability to provide evidence-based treatment recommendations for both OUD and AUD. Conclusions Brief addiction focused video-modules can improve confidence and knowledge in managing OUD and AUD among medical trainees.

Published: September 2023

The aeroengine bracket is a vital connector, which plays a key role in supporting and transmitting loads. In this paper, a bracket with variable stiffness for vibration control of aeroengine accessory is designed. Firstly, the topology optimization for the initial model of the aeroengine bracket is carried out, and the quality of the bracket was reduced by 84.78% while meeting the strength requirements. After that, part of the material of the bracket was replaced by shape memory alloy (SMA) to design the bracket with variable stiffness. It is found that with the increase in temperature, the stiffness of the designed bracket with variable stiffness increases by about 36%, and maximum von Mises stress and deformation of the bracket have decreased. Finally, the integrated modeling of aeroengine casing-bracket-accessory is carried out. Under single and coupled fault frequencies, the amplitude of the accessory is reduced by 57.5% and 63.1%, respectively. The frequency sweep at different temperatures shows that as the temperature increases, the resonance frequency changed from 74.6 Hz to 89.1 Hz and the resonance peak amplitude decreased by 17.7%.
