AbstractVoting plays a vital role in democratic societies. Adopting electronic voting can effectively increase voter participation and significantly reduce the financial burden on the organizers. In recent years, with the prevalence of blockchain technology, numerous blockchain-based electronic voting schemes have emerged. Compared with traditional electronic voting schemes, they have more favorable security features. However, existing schemes generally suffer from inefficient voting procedures, limited functionality, and dependence on specific blockchain platforms, making them challenging to deploy in diverse voting scenarios. This paper proposes an efficient and versatile electronic voting scheme on blockchain that addresses these problems using our proposed smart contract-based aggregated blind signature, zero-knowledge proofs, and threshold encryption scheme. In the paper, the scheme’s various features, including security, are analyzed in detail, and the scheme is deployed and tested on the Hyperledger Fabric and Ethereum blockchain platform. The experiment results demonstrate that the voting scheme satisfies the security requirement, and it has outstanding advantages in performance.

Published: November 2024

Abstract
Background
Aortoiliac injury after intervertebral disc surgery is an uncommon but potentially fatal complication. This case study emphasizes how crucial it is to identify this uncommon complication, which can manifest itself in a variety of ways, including leg oedema, heart failure, and deep vein thrombosis. This case is unique in that it presents with an uncommon post-spinal surgery complication of fistulized pseudoaneurysm of the common iliac artery and vein. This combination calls for an immediate diagnosis and careful care.

Case presentation
A 36-year-old female patient presented with progressively worsening orthopnea, accompanied by chest pain and palpitations. Her medical history revealed gradually increasing right lower limb swelling since three months, following a discectomy procedure for the management of lower back pain associated with a herniated lumbar disc at the L5-S1 level. Doppler ultrasonography demonstrated an arterialized flow within the right common iliac vein. Subsequent computed tomography angiography identified a pseudoaneurysm of the right common iliac artery, which had formed a fistulous connection to the right common iliac vein. This uncommon complication was likely attributable to prior disc surgery. The patient received endovascular intervention, which was executed in two primary stages: first, embolization of the right internal iliac artery was performed, followed by the exclusion of the arteriovenous fistula through the deployment of a covered stent graft within the right common iliac artery. The intervention successfully resolved both the pseudoaneurysm and the arteriovenous fistula.

Conclusions
This case report underscores the importance of considering vascular complications in patients presenting with unusual symptoms following intervertebral disc surgery, even after a significant time lapse. While both open surgical and endovascular approaches can yield good results in treating such complications, the endovascular method, as demonstrated in this case, is associated with minimal morbidity. This approach offers a less invasive alternative that can effectively manage complex vascular injuries resulting from disc surgery. Clinicians should be aware of this rare but serious complication to ensure timely diagnosis and appropriate management, potentially improving patient outcomes in similar cases.

AbstractThe classical properties of thermal light fields were instrumental in shaping our early understanding of light. Before the invention of the laser, thermal light was used to investigate the wave-particle duality of light. The subsequent formulation of the quantum theory of electromagnetic radiation later confirmed the classical nature of thermal light fields. Here, we fragment a pseudothermal field into its multiparticle constituents to demonstrate that it can host multiphoton dynamics mediated by either classical or quantum properties of coherence. This is shown in a forty-particle system through a process of scattering mediated by twisted paths endowed with orbital angular momentum. This platform enables accurate projections of the scattered pseudothermal system into isolated multiphoton subsystems governed by quantum dynamics. Interestingly, the isolated multiphoton subsystems exhibiting quantum coherence produce interference patterns previously attributed to entangled optical systems. As such, our work unveils novel mechanisms to isolate quantum systems from classical fields. This possibility opens new paradigms in quantum physics with enormous implications for the development of robust quantum technologies.

Abstract
Background
Dyscalculia, a specific learning disorder per the Diagnostic and Statistical Manual Fifth Edition (DSM-5), involves difficulties in math domains. Research on working memory’s link to dyscalculia is crucial for effective interventions in children with the disorder. This study aims to examine the cognitive characteristics of Egyptian children with developmental dyscalculia by evaluating their performance in verbal and visuospatial working memory. A cross-sectional study was conducted at the Unit of Phoniatrics, Ain Shams University. The study included 60 children, aged 8–11 years, split into two groups: 30 diagnosed with dyscalculia (with or without dyslexia), and 30 with typical development, matched for age and sex, and without any communication, language, speech, or learning disabilities. Both tests—the Test of Mathematical Abilities (TOMA-3) and the working memory test—were administered to both groups.

Results and conclusion
Cases group show notably lower scores on tests measuring dyscalculia and working memory when compared to the control group. The highest percentage of impairment observed is in visual memory. However, there is no clinically significant difference between phonological (auditory) memory and visual memory. The correlation analysis indicated that the visuospatial sketchpad correlates with mathematical symbols and computations, while the phonological (auditory memory) shows a significant positive correlation with word problems.

Published: November 2024

Abstract
Vibrio vulnificus, a gram-negative pathogenic bacterium, transmitted via undercooked seafood or contaminated seawater, causes septicemia and wound infections. In this study, we analyzed 15 clinical and 11 environmental isolates. In total, 20 sequence types (STs), including eight novel STs, were identified. Antibiotic resistance gene analysis commonly detected the cyclic AMP receptor protein (CRP) in both the clinical and environmental isolates. Interestingly, clinical and environmental isolates were non-susceptible to third-generation cephalosporins, such as ceftazidime and cefotaxime, complicating the treatment of V. vulnificus infection. Multiple antibiotic resistance (MAR) index ranged from 0.1 to 0.5, with clinical isolates showing a higher mean MAR index than the environmental isolates, indicating their broader spectrum of resistance. Notable, no quantitative (124.3 vs. 126.5) and qualitative (adherence, antiphagocytosis, and chemotaxis/motility) differences in virulence factors were observed between the environmental and clinical strains. The molecular characteristics identified in this study provide insights into the virulence of V. vulnificus strains in South Korea, highlighting the need for continuous surveillance of antibiotic resistance in emerging V. vulnificus strains.

PURPOSE
Breast conservation after systemic therapy requires accurate localization of the lesion and its margins, especially in nonpalpable tumors. The present study aims to describe a cost-effective technique of tumor localization using the combination of surgical clips and methylene blue.

METHODS
A minimum of three or four clips were inserted into the tumor to allow easy visualization of the clip mass. After insertion, measurements of the clips from the nipple and pectoral muscles were recorded to assess for clip migration. After chemotherapy, the disease and clip mass were localized intra-operatively using blue dye. A single-center review of breast conservations performed after neoadjuvant chemotherapy that used the above-described localization technique was undertaken. The primary aim was to assess successful detection and margin-negative resection rates.

RESULTS
The study included 65 patients, and the clip mass was detected on ultrasound following chemotherapy in all patients without clip migration. This detection was accurate even in cases of complete pathological and radiological response. Importantly, there were no procedure-related complications. Postchemotherapy disease localization was successfully achieved in all patients using the readily available and cost-effective methylene blue dye. No patient had an invasive margin positive at resection.

CONCLUSION
The combination of using multiple surgical clips and methylene blue is not only an extremely cheap and accurate technique for tumor site localization but also ensures precise surgical removal. The technique allows tumor localization even in low-income economies.
Racial/Ethnic Disparities in Oncology Clinical Trial Participation: Investigator Attitudes, Needs, and Motivation to Improve
Authors: Bransky Natalie P. , Walling Anne M. , Klomhaus Alexandra M. , Glaspy John A. , Garcia-Jimenez Maria D. 
Published: November 2024

PURPOSE
The perspective of all stakeholders involved in clinical trials is critical to addressing disparities in racial/ethnic minority (REM) clinical trial participation. Little is known about clinical trial investigator perspectives. To our knowledge, there are no published studies assessing differences in investigator perspectives on the basis of their primary role in clinical trials (ie, principal investigator [PI] or subinvestigator [sub-I]). Differences likely exist in investigator perspectives on the basis of having a more design-oriented (PI) or recruitment-oriented (sub-I) role.

MATERIALS AND METHODS
We conducted a cross-sectional, anonymous, pilot survey of 107 oncology clinical trial investigators at an academic center. The survey assessed five domains about disparities in REM clinical trial participation. We performed a subgroup analysis of mid- and late-career investigators (≥10 years of experience) comparing PIs (opened ≥one clinical trial in the past year) with sub-Is (did not).

RESULTS
Among 60 respondents, a majority (83%) strongly agreed disparities exist in REM clinical trial participation and that this is problematic (75%). Notably, 45% agreed they cannot directly address this problem. In the subgroup analysis, PIs were more likely to have received training about barriers/facilitators to REM clinical trial participation and strategies to increase participation. They were also more likely to endorse wanting help in this area.

CONCLUSION
Our results suggest clinical trial investigators are aware of disparities in REM clinical trial participation but do not feel they can address them. PIs are more likely to have received previous training on this topic and to want help to improve their ability to address disparities. More studies are needed to inform targeted interventions and structural improvements to enhance investigators' self-efficacy for improving REM participation in oncology clinical trials.
The Intergenerational Legacy of Indian Residential Schools
Authors: Jones Maggie E. C. 
Published: November 2024

Abstract
From the late nineteenth century until the end of the twentieth century, the Canadian government collaborated with Christian churches to operate a network of boarding schools for Indigenous children to culturally and economically assimilate them. These children were taken from their families and placed into residential schools, where they were to be assimilated into the Eurocentric culture of the dominant society. Using a unique restricted-access database that asked Indigenous respondents about their family history with residential schools, in addition to questions on socioeconomic outcomes, I study the intergenerational effects of these schools. Despite previous research showing that residential schools increased human capital accumulation among attendees, I find that residential schools are associated with lower educational attainment among subsequent generations. I present evidence consistent with the notion that both cultural detachment and a breakdown in family relationships contributed to a reversal of the standard relationship between parents’ and children's human capital. Encouragingly, I find suggestive evidence that greater access to cultural centers might buffer the harmful legacy of this historical trauma.
Labor-Replacing Automation and Finance
Authors: Cheng Xin , Lyandres Evgeny , Zhou Kaiguo , Zhou Tong 
Published: November 2024

We examine the effects of adoption of labor-replacing automation technology on corporate financing. Empirically, using Chinese firm-level panel data on deployment of industrial robots as an example of such automation, we find that robot adoption increases leverage and reduces cost of debt. We hypothesize that the underlying reason is that being a substitute for labor, automation provides a hedge against fluctuations in labor costs. A model based on this hedging argument delivers additional testable predictions concerning determinants of the relation between automation and corporate financing. These relations are borne out in the data, providing support for the proposed mechanism. Our evidence is inconsistent with alternative channels behind the observed relations.

Estimating Demand with Unobserved No-Purchases on Revenue-Managed Data
Authors: Li Anran , Talluri Kalyan , Tekin Müge 
Published: November 2024

Problem definition: This paper studies the joint estimation of the consumer arrival rate and choice model parameters when “no-purchasers” (customers who considered the product but did not purchase) are not observable. Estimating this unconstrained demand even with the simplest discrete-choice model such as the multinomial logit (MNL) becomes challenging as we do not know the fraction that have chosen the outside option (i.e., not purchased). Methods have been proposed to use market share to pin down the parameter associated with the outside option. However, market share data are difficult to obtain in many situations, and in some industries, such as fashion retail, have little meaning as the items are difficult to compare. In this paper, we point out an additional difficulty that can arise in practice: Many firms monitor sales and optimize their prices and assortments within the sale period as part of their revenue management (RM) process, based on partially observed demand. This can potentially cause a revenue management induced endogeneity as the data used for estimation is the result of optimization (in turn based on prior data) to set controls. As we demonstrate, methods that work well on randomly generated assortments may do badly on optimized assortment data. Methodology/results: In this paper, we propose a robust method when the firm cannot observe no-purchases and has no market share information, and the data have been revenue-managed. We develop a two-step generalized method-of-moments (GMM) procedure that is based on a modified moment condition, and importantly, does not require instrumental variables (IVs), a significant advantage in practice. Managerial implications: In Monte Carlo simulations, the performance of our method matches existing methods when the controls are generated randomly, and is robust under all conditions, whether RM-induced endogeneity is present or not. On a large real-world data set from the fashion industry, subject to stock-outs and markdown pricing along with unknown management controls, our method provides robust estimates compared with existing methods without requiring any input on market shares, which is especially difficult to pin down at a category and season/collection level.

DeLuxing: Deep Lagrangian Underestimate Fixing for Column-Generation-Based Exact Methods
Authors: Yang Yu 
Published: November 2024

Advancing Column Generation by a Novel Variable Fixing Method In the paper titled “DeLuxing: Deep Lagrangian Underestimate Fixing for Column-Generation-Based Exact Methods,” Dr. Yu Yang introduces DeLuxing—an innovative variable-fixing technique that significantly advances column-generation-based exact methods for solving large-scale optimization problems, particularly vehicle routing problems (VRPs). DeLuxing leverages a novel linear programming formulation with a small subset of the enumerated variables, which is theoretically guaranteed to yield qualified dual solutions for computing Lagrangian underestimates. By eliminating over 75% of the unnecessary variables, DeLuxing drastically boosts computational efficiency, doubling the size of CMTVRPTW (capacitated multitrip vehicle routing problem with time windows) instances that can be solved optimally. Additionally, this breakthrough accelerates top VRP solvers like RouteOpt by up to 71%. The core concept underpinning DeLuxing extends to broader contexts such as variable type relaxation and cutting plane addition, achieving an additional 25% speedup for difficult instances.

Introduction
Flavoring in cigarillos contributes to greater product initiation and abuse liability particularly among young adults. Few studies have examined how packaging elements, including flavor, may draw visual attention from potential consumers as well as impact product recall. This study aimed to test the difference in visual attention to flavor names and other packaging elements on cigarillo products as well as recall of these packaging elements.

Materials and methods
Young adults aged 16–28 years were recruited to participate in a randomized control trial (Clinictrials.org ID: NCT04358705) in June through December 2022 (N = 89). Participants were randomized to two conditions viewing 12 flavored or unflavored cigarillo package images. Eye tracking software captured participants viewing (dwell) time on package features: flavor, brand, health warning, price, and other package imagery. Participants were asked about their recall of the images viewed. The proportion of dwell time on each package elements were used to examine differences between experimental conditions.

Results
Across conditions, participants spent the greatest proportion of dwell time looking at the health warning. Participants in the flavored condition spent a significantly greater proportion of dwell time looking at flavor name (mean: 10.66%; SD: 3.56) compared to those in the unflavored condition (mean:7.03%; SD 2.81). Following the experiment, 45.8% of those in the flavored condition recalled having seen flavors or flavor names, which was greater than recall of all other elements and was significantly greater than flavor recall in the unflavored condition (12.2%).

Conclusions
Flavored cigarillos attract greater visual attention and were the most memorable element of cigarillo packaging among young adults sampled. Changes to cigarillo packaging, including limiting flavor descriptors, imagery, and/or color on packaging and advertisements may be an effective way to reduce young adults’ attention to the products and thus their appeal.
