Abstract
Urbanization is known to elevate storm runoff, but how it influences carbon cycle and ecosystem productivity through altering the evapotranspiration (ET) process is less clear. We examined the combined effects of urbanization including change in impervious surface area (ISA) and climate variability on the water and carbon balances of the Qinhuai River Basin (QRB) over 2001–2018. QRB represents a typical rice paddy-dominated region that experienced rapid urbanization in southern China. We improved a monthly scale water supply stress index ecosystem service model by integrating local eddy flux measurements and high-resolution remote sensing data. We found a significant downward trend in both ET (−4.6 mm yr−1, p < 0.05) and gross primary productivity (GPP) (−10.4 gC m−2 yr−1, p < 0.05) but a significant upward trend in water yield (Q) (+28.6 mm yr−1, p < 0.05). These ecosystem function changes coincided with a 96% increase in urban areas, 1.9-fold increase in ISA, and a 37% reduction in rice paddy fields. The mean annual watershed GPP decreased from 1048 gC m−2 to 998 gC m−2 while the annual Q increased from 284 mm to 669 mm from 2001 to 2018. Scenario modeling experiments suggested that the negative impacts of loss of rice paddy fields and increase in ISA on ET and GPP overwhelmed the positive impacts of climate warming. The reduction in GPP and increase in Q were largely attributed to the increases in ISA, not necessarily due to changes in land use types (e.g. urban area). The expansion of urban area, increase in ISA and reduction in leaf area index, and increase in precipitation explained the increase in Q. Our research offers insight about the interactions of carbon and water cycles through the critical ET processes under a changing climate and land surface characteristics at a watershed level. Our modeling tool and analysis provides land managers and policy makers information for designing effective ‘Urban Nature-based Solutions’ to mitigate the negative environmental effects of urbanization on carbon and water resources.
Proof of bulk-edge correspondence for band topology by Toeplitz algebra
Authors: Zhou Zixian , Wan Liang-Liang 
Published: October 2024

Abstract
We rigorously yet concisely prove the bulk-edge correspondence for general d-dimensional (dD) topological insulators in complex Altland–Zirnbauer classes, which states that the bulk topological number equals to the edge-mode index. Specifically, an essential formula is discovered that links the quantity expressed by Toeplitz algebra, i.e. hopping terms on the lattice with an edge, to the Fourier series on the bulk Brillouin zone. We then apply it to chiral models and utilize exterior differential calculations, instead of the sophisticated K-theory, to show that the winding number of bulk system equals to the Fredholm index of 1D edge Hamiltonian, or to the sum of edge winding numbers for higher odd dimensions. Moreover, this result is inherited to the even-dimensional Chern insulators as each of them can be mapped to an odd-dimensional chiral model. It is revealed that the Chern number of bulk system is identical to the spectral flow of 2D edge Hamiltonian, or to the negative sum of edge Chern numbers for higher even dimensions. Our methods and conclusions are friendly to physicists and could be easily extended to other physical scenarios.
Efficient algorithm for thermal nondestructive testing and evaluation by considering the heteroscedastic nature of noise sources in infrared thermography
Authors: Kaur Jasleen , Babu Prabhu , Mulaveesala Ravibabu 
Published: October 2024

Abstract
Thermal Imaging is a promising Non Destructive Testing & Evaluation (NDT & E) approach to monitor the health of composite materials. Among various post processing approaches adopted in thermal imaging for NDT & E, statistical analysis schemes gained importance due to their reliability and data reduction capabilities. This paper provides an insight to a factor analysis-based statistical approach to detect the hidden defects in the Glass Fiber Reinforced Polymer (GFRP) sample. The proposed approach models the observed data covariance into combination of temporal signal covariance and noise covariance matrices. The modeling of the diagonal covariance matrix (with different elements) is motivated by the presence of heterogeneity in the experimental data obtained from GFRP sample.This novel method is based on the coordinate descent technique, which estimates the covariance matrix of the noise variances iteratively by minimizing the negative log likelihood function. The obtained results from the chosen GFRP samples compared with the widely used statistical Principal Component Thermography (PCT) technique illustrate the improved performance in terms of defect detection with the proposed technique.
How regenerated cellulose fibers appear in the discourse on marine pollution with microplastic: a snowballing and network approach
Authors: Pasterk Sophie , Ranacher Lea , Stern Tobias , Schuster K Christian , Aigner Danuta J , Hesser Franziska 
Published: October 2024

Abstract
Microplastics are prominent marine pollutants that have been investigated in various recent studies. While some of these studies mention regenerated cellulose fibers (RCFs), as part of microplastics or in close connection, other studies consider RCFs to be biodegradable by their nature and hence neglectable in context of marine pollution. This systematic literature review on the biodegradability of RCFs was conducted to investigate how such differences can be explained. An innovative snowballing-network approach has been applied for the review to gain a better understanding of historical developments of and interconnections between according strains of literature. Starting from four different papers the review followed according references and citations. Results indicate that a consensus is lacking across research fields on the chemical characteristics of RCFs. The inconsistent use of existing terminology by some researchers, and failure to make distinctions between RCFs and synthetic fibers or plastics in the results may lead to misinterpretation regarding the impacts of RCFs in the environment. By using more accurately the existing terms and definitions, researchers could prevent readers from misinterpreting research results and increase their understanding of RCFs. Biodegradation of regenerated cellulose fibers was reviewed, and consensus is that these fibers are biodegradable in all natural environments and suitable industrial settings. Conducting further research on the fate of RCFs and other cellulose fibers from processed consumer products like textiles, as well as microfibers from textiles in general, in natural environments are recommended.
Metal substrate printed circuit boards as low-cost, robust temperature sensor mounts for cryogenic thermometry
Authors: Stöckli Linus Leo , Ottersberg Rafael , Thomas Nicolas 
Published: October 2024

Abstract
Cryogenic experiments strongly depend on accurate temperature measurements. Many of the sensors used for these purposes are glued to the object to be measured to achieve adequate thermal contact. This calls for a more flexible, long lasting and robust bolt-mounted solution. Therefore, we present a low-cost (<5$), compact, PCB (printed circuit board) based sensor mount for RTDs (resistance temperature detector) and diodes showing reliable results at temperatures from 50 K to 400 K with possible modifications for an extended range down below 20 K. We anticipate that the robustness and low cost of the reported sensor mount design will strongly enhance the accessibility of reliable temperature measurements at a wide range of temperatures in laboratory applications.
Misconceiving the ‘Indian Family’
Authors: Vera-Sanso* Penny 
Published: October 2024

Abstract
This chapter interrogates conceptualizations of family and household in India and their consequences for public discourse, public policy, and rights within households. It identifies how the presumption that the joint family is India’s cultural norm misrepresents the family cycle on which joint families are predicated and blames cultural erosion for social ills. This both pulls the socio-economic and demographic determinants of family relations out of the analytical frame and reduces government roles to family norm enforcer, rather than rights upholder and social protection floor provider. Misconceiving inter-household and intra-household relations drives policies that undermine essential inter-household support strategies. Drawing on three decades of fieldwork in urban and rural India, the chapter demonstrates the mismatch between Census definitions of households, that emphasize fixed boundaries and household independence, and the lived reality of household interdependence and the flexing of household boundaries in order to provide shelter and support to relatives.
Digital Mothering in Middle-Class Families
Authors: Venkatraman Shriram 
Published: October 2024

Abstract
The rise of dual-income nuclear families in urban environments has led to an increase in latchkey children. Working parents, particularly mothers, face the challenge of balancing work and home life and often employ digital parenting methods to monitor and guide their children’s media consumption. They often promote content that aligns with their intergenerational class aspirations while discouraging others. To perform their role well, these mothers often seek inputs from social networks of similarly situated women through digital platforms while manoeuvring constant inputs on motherhood from their extended family networks. These digital platforms also become places where mothers interact, share knowledge, and even compete in showcasing parenting skills and aspirations. This chapter will examine how these influences shape a notion of responsible digital mothering, impacting the child’s media consumption patterns and reproducing class status. The chapter is based on a long-term ethnography conducted since 2013 in Chennai, South India.
Pervasive Stagnation: Flat and Rising Cardiovascular Disease Mortality Post-2010 Across US States and Counties
Authors: Abrams Leah , Brower Nora , Myrskylä Mikko , Mehta Neil 
Published: October 2024

Abstract
Since 2010, the U.S. has experienced adverse trends in cardiovascular disease (CVD) mortality, which dramatically slowed long-standing life expectancy improvements. The extent to which the national trend in CVD mortality masks heterogeneity in trends across states and counties is poorly understood. We provide a detailed accounting of post-2010 trends in CVD mortality by U.S. state and county to understand how features of place relate to trends. We compare trends during 2010-2019 to that of 2000-2009. We observe flattening declines in CVD mortality in nearly every state at both midlife (ages 40-64) and old age (ages 65-84) across the two decades. Many states exhibited increases in midlife CVD mortality in 2010-2019. Old age CVD mortality was still declining in most states post-2010, although much slower compared to the previous decade. States in the Southeast recorded some of the fastest post-2010 declines in CVD mortality at old age. County-level median household income was associated with level of CVD mortality, but all income deciles, even the wealthiest counties, experienced stagnating CVD mortality declines. Findings highlight the ubiquitous nature of CVD stagnation, pointing to the need to identify risk factor affecting trends across regions and socioeconomic strata across the United States.
A Criminological–Military Enterprise
Authors: McGarry Ross 
Published: October 2024

Abstract
This article builds upon, and extends, critiques of British criminology’s enterprising collaboration with state-based institutions. Through an investigation of the discipline’s discreet contribution to the UK military ‘knowledge economy’ (Catignani and Basham 2021), criminological research is revealed as having the capacity to insulate the British military from critique and depoliticize military violence. Informed by criminological and critical military studies scholarship, the ‘criminological–military enterprise’ is introduced into academic discourse. This term offers a critical analysis of the discipline’s contemporary ‘blended’ (Shields 2024) research with the British military estate, provides ‘enriched reflexive’ (Danielsson 2022) problems for critical scholars to contemplate, and calls for a (re)politicization of military issues within criminological research.
Granulomatous secondary syphilis: two case reports and a literature review
Authors: Lim Delwyn Z J , Lim Joel H L , Wang Ding Yuan , Chio Martin T W 
Published: October 2024

Abstract
Historically, granulomatous inflammation has been described in association with tertiary syphilis. However, in recent years there have been increasing reports of granulomatous inflammation in patients with secondary syphilis. Here, we discuss two patients who presented with erythematous infiltrated papules and nodules and were eventually diagnosed with granulomatous secondary syphilis, with clearance of their rashes following treatment. We highlight important clues that can point clinicians and histopathologists toward a diagnosis of syphilis instead of differential diagnoses such as leprosy in reaction, cutaneous histiocytosis and lymphoma. Furthermore, after performing a literature review and from our own experiences, we wish to highlight that granulomatous syphilis is often palmoplantar-sparing and its presence may not necessarily be a feature of immunocompromised states, such as HIV infection. In this increasingly connected world, the recognition of an atypical presentation of an age-old disease in patients with different skin types must be underscored by close clinicopathological correlations.
The divisive normalization model of visual number sense: model predictions and experimental confirmation
Authors: Croteau Jenna , Fornaciai Michele , Huber David E , Park Joonkoo 
Published: October 2024

Abstract
Our intuitive sense of number allows rapid estimation for the number of objects (numerosity) in a scene. How does the continuous nature of neural information processing create a discrete representation of number? A neurocomputational model with divisive normalization explains this process and existing data; however, a successful model should not only explain existing data but also generate novel predictions. Here, we experimentally test novel predictions of this model to evaluate its merit for explaining mechanisms of numerosity perception. We did so by consideration of the coherence illusion: the underestimation of number for arrays containing heterogeneous compared to homogeneous items. First, we established the existence of the coherence illusion for homogeneity manipulations of both area and orientation of items in an array. Second, despite the behavioral similarity, the divisive normalization model predicted that these two illusions should reflect activity in different stages of visual processing. Finally, visual evoked potentials from an electroencephalography experiment confirmed these predictions, showing that area and orientation coherence modulate brain responses at distinct latencies and topographies. These results demonstrate the utility of the divisive normalization model for explaining numerosity perception, according to which numerosity perception is a byproduct of canonical neurocomputations that exist throughout the visual pathway.
Distal solution for an (un)conventional radial artery complication: a case report
Authors: Colletti Giuseppe , Sgueglia Gregory Angelo , Gach Olivier , Natalis Alexandre , Ungureanu Claudiu 
Published: October 2024

Abstract

Background
The European Society of Cardiology guidelines recommend transradial access (TRA) for coronary angiography due to its advantages, including lower mortality and bleeding complications. Arterial pseudoaneurysms are rare but challenging complications of TRA, occurring in 0.009%–0.05% of procedures. Non-surgical management, especially in cases with large (&gt;1 mm) necks or late discovery, can be difficult due to the limited effectiveness of echo-guided compression and risks of echo-guided thrombin injection, like thrombin embolization leading to necrosis.

Case summary
An 82-year-old underwent successful non-surgical management of a large-neck pseudoaneurysm following TRA for a primary percutaneous coronary intervention of the left anterior descending artery. Clinical examination revealed a pulsatile mass at the puncture site, diagnosed via ultrasound as a pseudoaneurysm with a &gt;1 mm neck. Through distal radial access, an initial 5 Fr sheath was upsized to 8 Fr based on ultrasound findings, achieving complete pseudoaneurysm exclusion. Follow-ups confirmed pseudoaneurysm sealing and radial artery patency.

Discussion
This case illustrates an effective non-surgical approach to managing large-neck pseudoaneurysms post-TRA, utilizing an upsized sheath technique. It underscores the importance of innovative non-surgical strategies in complex cases, providing a safe and effective alternative to traditional management methods.
Symptomatic orthostatic hypotension due to standing mid-left ventricular obstruction: a case report
Authors: Ordine Leopoldo , Losi Maria Angela , Canciello Grazia , Borrelli Felice , Esposito Giovanni 
Published: October 2024

Abstract

Background
Orthostatic hypotension (OH) is a common cardiovascular disorder typically associated with autonomic dysfunction. However, various other mechanisms can contribute to its occurrence.

Case summary
An 88-year-old woman was referred to the cardiology unit due to recurrent syncope episodes while standing. Echocardiography revealed a normally contracting left ventricle with severe hypertrophy, a restrictive filling pattern, reduced stroke volume, and a decreased inferior vena cava diameter (4 mm/m²). In the standing position, she experienced syncope, and invasive blood pressure monitoring confirmed OH, alongside a normal increase in heart rate and evidence of mid-left ventricular obstruction (MVO) on echocardiogram. Discontinuation of diuretics and administration of fluids and beta-blockers effectively resolved the OH.

Discussion
This case underscores the importance of considering mechanisms beyond autonomic dysfunction and volume depletion in the aetiology of OH in elderly patients. Notably, this is the first documented case of OH associated with MVO occurring in an upright posture, resulting in a significant decrease in cardiac output and subsequent syncope. Preventing volume depletion and using non-vasodilating beta-blockers may represent optimal therapeutic strategies in such cases.
Complex left atrial appendage closure using 3D printing system simulation in a patient with mitral prosthetic valve: a case report
Authors: Vicini Scajola Luca , Sanzo Antonio , Magrini Giulia , Marconi Stefania , Rordorf Roberto 
Published: October 2024

Abstract

Background
Left atrial appendage (LAA) closure (LAAc) has emerged as a safe and effective alternative to oral anticoagulation (OAC) for stroke prevention in patients with atrial fibrillation (AF) and contraindications to OAC.

Case summary
A 61-year-old woman with permanent AF and a history of mitral surgery replacement with mechanical prosthesis was referred to our cardiology department to undergo LAAc. The preoperative computed tomography (CT) revealed that the ostium of the LAA was close to the mitral prosthesis ring. As a result of the difficult LAA morphology, a CT image-based virtual model was created, then a 3D printing model was prepared in our laboratory, and procedure simulation was performed with the two different LAA occlusion devices (plug- vs. pacifier-like models) to see which one was more suitable for the patient anatomy.

Discussion
In this case of complex LAAc in a patient with mechanical prosthetic mitral valve, the use of a 3D printed model has guided prosthesis selection and device sizing reducing procedure time and complications.
