Published: January 2025

Abstract
New axial piston pumps with fixed displacement volumes, such as the high efficient power package (HEPP) pumps operate at variable rotational speeds and thus variable flow rates in a wide range. Using intelligent pump control systems, small and light packages are possible. In contrast, the fluid pulsations vary due to the rotational speed and have to be controlled avoiding stress or wear in the hydraulic system components (e.g. seals of tubing) and potentially impacting cabin noise. Due to the excitation frequencies, a broadband silencer for high pressure applications is required. This is realised by a multi-Helmholtz-resonator (MHR) concept within one cylindrical volume. The design will be adapted for pump-specific frequency characteristics in aircraft hydraulic conditions and fine adjusted during test verification by means of an adjustable tube-inside a pressure shell. For cost, weight and complexity reason a common broadband attenuator is integrated in the hydraulic circuit connecting the two redundant HEPP motorpumps. The attenuator position is optimised to achieve maximal acoustic performance and minimize pulsation stress on the pump, especially at the main operating point. The proof of concept has been achieved experimentally comparing a HEPP piston pump with and without the MHR.
Symmetry in the developmental stages of permanent human teeth: a comparative study between maxilla and mandible
Authors: Haghi Ashtiani G. , Davies J. A. , Liversidge H. M. 
Published: January 2025

Abstract

Objective
The aim of this study was to assess symmetry of developmental stage of permanent teeth between the left and right side of the jaw, as well as between the maxilla and the mandible.

Methods
A sample of 150 panoramic radiographs of individuals aged 6–20 years (69 males, 81 females) were selected from an open-access radiographic collection (Maxwell Museum of Anthropology’s orthodontic collection, Albuquerque, USA). All developing immature permanent teeth (n = 489) were scored by the first author using Moorrees and Demirjian tooth stages. Symmetry of developing teeth was assessed between the left and right sides of the jaw, as well as between the maxilla and the mandible using McNemar test with p < 0.05 considered significant.

Results
No significant differences were found comparing left and right sides within the maxilla (n = 489), (McNemar, p = 0.759 M, p = 0.736 D), or within the mandible (McNemar, p = 0.262 M, p = 0.707 D) using either tooth scoring method. Percentage agreement for individual teeth between left and right sides was least for third molars. Significant differences were observed comparing maxillary and mandibular teeth for both tooth scoring methods (n = 978), (McNemar, p = 0.00 M, p < 0.001 D). Percentage agreement for individual teeth between the maxilla and mandible was least for incisors.

Conclusion
In the present sample, differences in tooth formation were not significantly different in left and right side of the jaw while a significant difference (p = 0.00 M, p < 0.001 D) was observed between maxilla and mandible.
Enhanced-Similarity Attention Fusion for Unsupervised Cross-Modal Hashing Retrieval
Authors: Li Mingyong , Ge Mingyuan 
Published: January 2025

Abstract
Although the fact that current methods have some effects, unsupervised cross-modal hashing methods still face several common challenges. First of all, the text features that have been collected from text data are not comprehensive enough to provide sufficient guidance for building textual modal similarity matrices. Secondly, the fusion of similarity matrices from different modalities lacks adaptability, leading to a less accurate final similarity matrix. This work suggests Enhanced Similarity Attention Fusion Hashing (ESAFH) as a remedy for these problems. Firstly, we construct a text encoder to enrich text features, an adjacency matrix is built to represent the association relationship between pairs of samples. Additionally, it is thought that features can be extracted from the sample and its semantic neighbor samples to enhance text features. Furthermore, we enhance the original similarity matrix by incorporating related information. This step aims to improve the accuracy of similarity estimation by considering the enriched text features obtained in the previous step. Finally, we introduce an enhanced attention fusion mechanism. This mechanism adaptively fuses the similarity matrices from different modalities, creating a unified inter-modal similarity matrix. This fused matrix guides the learning of hash functions by preserving the most relevant information from each modality. Through comprehensive experiments on the three popular datasets, the suggested ESAFH method is thoroughly assessed. The findings show that on these datasets, ESAFH performs satisfactorily in cross-modal retrieval tasks. In conclusion, by boosting text features, improving the similarity matrix, and utilizing an attention fusion mechanism, ESAFH solves the shortcomings of current methods.
Recent advances in organic fluorophores as anti-counterfeit agents: an up-to-date review
Authors: Akshaya N , Thomas Annette , Martis Glanish Jude , Gaonkar Santosh L. 
Published: January 2025

Abstract
The problems of counterfeiting and duplicating valuable products such as confidential papers, banknotes, passports, nationality cards, and other vital documents have been increased exponentially. This poses a major challenge for companies, governments and for customers as well. According to a report published in 2017, the market for counterfeiting was found to be 107.26 billion dollars annually which increased to 206.57 billion dollars in 2021. Researchers are constantly looking for various strategies to effectively combat the problem of counterfeiting. Fluorescent molecules such as stimuli-responsive molecules, aggregation induced emission (AIE) luminogens such as tetraphenylethylene (TPE), heterocyclic complexes and photochromic-infused nanoparticles have been used to develop efficient security inks with maximum security and quick authentication. This review discusses various types of organic fluorophores used for developing safe inks and anti-counterfeit labels in recent years. This would help researchers in this field choose and design suitable molecules or derivatives for developing solutions for counterfeiting practices.

Published: January 2025

Abstract

Background
Lipids are known to be involved in carcinogenesis, but the associations between lipid profiles and different lung cancer histological classifications remain unknown.

Methods
Individuals who participated in national adult health surveillance from 2012 to 2018 were included. For patients who developed lung cancer during follow-up, a 1:2 control group of nonlung cancer participants was selected after matching. Multivariate conditional logistic regression was used to explore the associations between lipid profiles, different lung cancer histological classifications and epidermal growth factor receptor mutation statuses. Subgroup, sensitivity, and dose‒response analyses were also performed.

Results
A total of 4,704,853 participants (30,337 lung cancer participants and 4,674,516 nonlung cancer participants) were included. In both the main and sensitivity analyses, the associations remained constant between lower high-density lipoprotein (HDL) cholesterol levels and a higher risk of lung cancer (main analysis: odds ratio: 1.13 [1.08–1.18]) and squamous cell carcinoma (1.29 [1.16–1.43]). Hypertriglyceridemia was associated with a lower risk of adenocarcinoma (0.90 [0.84–0.96]) and a higher risk of small cell lung cancer (1.31 [1.11–1.55]). Hypercholesterolemia was associated with a lower risk of squamous cell carcinoma (0.84 [0.76–0.94]). In the subgroup analysis, lower HDL cholesterol levels were associated with greater risk across most subgroups. HDL cholesterol levels also demonstrated a dose‒response association with the development of lung cancer.

Conclusions
The distinct associations between specific lipid profiles and lung cancer subtypes suggest that lipid metabolism may play different mechanistic roles in lung cancer development.
Reversibility of acrocyanosis and improvement of capillaroscopic pattern in a patient with polycythemia vera treated with ruxolitinib: a case report
Authors: Nigro Angelo 
Published: January 2025

Abstract
This case report describes the clinical course of a 78-year-old patient diagnosed with polycythemia vera (PV), who presented with pronounced acrocyanosis of the hands in 2021. The patient was treated with hydroxyurea (oncocarbide), and nailfold capillaroscopy revealed an “abnormal pattern” characterized by pronounced architectural disarray and capillary tortuosity, which is uncommon in patients with myeloproliferative neoplasms (MPNs). In 2023, owing to suboptimal symptom management and hematological side effects, the treatment was switched to ruxolitinib, which led to significant clinical improvements by 2024, including near-complete resolution of acrocyanosis and substantial improvement in capillaroscopic abnormalities, with only residual capillary tortuosity noted. This case emphasizes the need for individualized therapeutic interventions for PV, and underscores the potential role of ruxolitinib in ameliorating microvascular dysfunction.
Beyond Borders: An Empirical Analysis of the “Fresh From Florida” State Marketing Program
Authors: Magnier Alexandre , Chen Lijun Angelia , Kassas Bachir , Morgan Kimberly 
Published: January 2025

Abstract
In this paper, we examine the effect of the “Fresh From Florida” marketing program on the preferences of consumers located in geographically distant regions. We administered a choice experiment to consumers from the Northeastern region of the US, the Eastern region of Canada, and from Florida. Our findings show that the logo recall rate is significant for out-of-state consumers. While the WTP for the “Fresh from Florida” attribute is not statistically significant for Northeastern US respondents, logo recall positively influences the WTP. Logo recall positively affects WTP in Canada, but only for respondents with positive or neutral opinions of Florida.

Authors: Swinnerton Kaitlin , Fillmore Nathanael R. , Oboho Ikwo , Grubber Janet , Brophy Mary , Do Nhan V , Monach Paul A , Branch-Elliman Westyn 
Published: January 2025

Abstract

Background:
COVID-associated pulmonary aspergillosis (CAPA) was described early in the pandemic as a complication of SARS-CoV-2. Data about incidence of aspergillosis and characteristics of affected patients after mid-2021 are limited.

Methods:
A retrospective, nationwide cohort of US Veterans with SARS-CoV-2 from 1/1/2020 to 2/7/2024 was created. Potential cases of aspergillosis ≤12 weeks of a SARS-CoV-2 test were flagged electronically (based on testing results indicative of invasive fungal infection, antifungal therapy, and/or ICD-10 codes), followed by manual review to establish the clinical diagnosis of pulmonary aspergillosis. Incidence rates were calculated per 10,000 SARS-CoV-2 cases. Selected clinical characteristics included age >70, receipt of immune-compromising drugs, hematologic malignancy, chronic respiratory disease, vaccination status, and vaccine era. Multivariate logistic regression was used to estimate the independent effects of these variables via adjusted odds ratios (aOR).

Results:
Among 674,343 Veterans with SARS-CoV-2, 165 were electronically flagged for review. Of these, 66 were judged to be cases of aspergillosis. Incidence proportions ranged from 0.30/10,000 among patients with zero risk factors to 34/10,000 among those with ≥3 risk factors; rates were similar in the pre- and post-vaccination eras. The 90-day mortality among aspergillosis cases was 50%. In the multivariate analysis, immune suppression (aOR 6.47, CI 3.84–10.92), chronic respiratory disease (aOR 3.57, CI 2.10–6.14), and age >70 (aOR 2.78, CI 1.64–4.80) were associated with aspergillosis.

Conclusions:
Patients with underlying risk factors for invasive aspergillosis continue to be at some risk despite SARS-CoV-2 immunization. Risk in patients without immune suppression or preexisting lung disease is very low.

Published: January 2025

Abstract

Objective:
Previous studies have linked social behaviors to COVID-19 risk in the general population. The impact of these behaviors among healthcare personnel, who face higher workplace exposure risks and possess greater prevention awareness, remains less explored.

Design:
We conducted a Prospective cohort study from December 2021 to May 2022, using monthly surveys. Exposures included (1) a composite of nine common social activities in the past month and (2) similarity of social behavior compared to pre-pandemic. Outcomes included self-reported SARS-CoV-2 infection (primary)and testing for SARS-CoV-2 (secondary). Mixed-effect logistic regression assessed the association between social behavior and outcomes, adjusting for baseline and time-dependent covariates. To account for missed surveys, we employed inverse probability-of-censoring weighting with a propensity score approach.

Setting:
An academic healthcare system.

Participants:
Healthcare personnel.

Results:
Of 1,302 healthcare personnel who completed ≥2 surveys, 244 reported ≥1 positive test during the study, resulting in a cumulative incidence of 19%. More social activities in the past month and social behavior similar to pre-pandemic levels were associated with increased likelihood of SARS-CoV-2 infection (recent social activity composite: OR = 1.11, 95% CI 1.02–1.21; pre-pandemic social similarity: OR = 1.14, 95% CI 1.07–1.21). Neither was significantly associated with testing for SARS-CoV-2.

Conclusions:
Healthcare personnel social behavior outside work was associated with a higher risk for COVID-19. To protect the hospital workforce, risk mitigation strategies for healthcare personnel should focus on both the community and workplace.
Congressional position-taking on punitive tariffs: president Trump’s 2018 auto tariff
Authors: Rocca Michael S. , Wang Miao 
Published: January 2025

Abstract
On 1 March 2018, President Trump declared a 25% tariff on certain steel imports by invoking Section 232 of the 1962 Trade Expansion Act. The tariff pitted two of America’s most storied and interconnected industries, steel and auto producers, against one another and made allies out of longtime bitter political opponents on Capitol Hill. Later that same year, President Trump doubled down on the steel tariff when he initiated a Section 232 investigation on auto and auto parts imports. The auto industry blasted the proposal, while steel offered its strong support. This paper examines the congressional response to President Trump’s proposed auto tariff. Specifically, we explain why 159 MCs signed a letter opposing the tariff. After controlling for other factors, such as district interests and campaign contributions, we find that ideology matters more than party affiliation on whether legislators signed the auto letter. We also find the second dimension of the DW-NOMINATE score to matter, suggesting the strong presence of intra-party cleavages. Our findings highlight the complex nature of trade policy as a domain of bipartisan agreement amidst broader political polarization and at a time when traditional party platforms on the issue are rapidly changing.
Worst-Case Performance for Real-Time Systems
Authors: Schoeberl Martin , Jellum Erling , Lin Shaokai , Jerad Chadlia , Maroun Emad Jacob , Lohstroh Marten , Lee Edward A 
Published: January 2025

Abstract
Real-time systems need to be built out of tasks for which the worst-case execution time is known. To enable accurate estimates of worst-case execution time, some researchers propose to build processors that simplify that analysis. These architectures are called precision-timed machines or time-predictable architectures. However, what does this term mean? This paper explores the meaning of time predictability and how it can be quantified. We show that time predictability is hard to quantify. Rather, the worst-case performance as the combination of a processor, a compiler, and a worst-case execution time analysis tool is an important property in the context of real-time systems. Note that the actual software has implications as well on the worst-case performance. We propose to define a standard set of benchmark programs that can be used to evaluate a time-predictable processor, a compiler, and a worst-case execution time analysis tool. We define worst-case performance as the geometric mean of worst-case execution time bounds on a standard set of benchmark programs.
Generative AI and international standardization
Authors: Hallensleben Sebastian 
Published: January 2025

Abstract
Standards complement regulation as frameworks for Artificial Intelligence governance. Within the European Union, this complementarity is laid down as the New Legislative Framework. Standards can be harmonised to provide a presumption of conformity with regulation. They draw legitimacy from the inclusion of all relevant stakeholders as well as the consensus principle although there are limitations in practice. At both European and international levels, standardisation for generative AI is still in its infancy due to standardisation following relying on a level of technical maturity. Therefore, most activity is currently seen in the policy domain. Potential directions for future generative AI standards are suggested. Generative AI drives the need for non-AI standards, too, especially in areas of digital trust and digital identity.
What Determines the Duration of Protest Events? Evidence from Africa
Authors: Lewis Jacob S. , Favell William 
Published: January 2025

Abstract
What determines why some protest events last only a single day while others can stretch over multiple days? This study presents the first cross-national quantitative analysis of the factors that shape protest event duration. This study argues that protest event duration is the function of factors that increase momentum (e.g. protest size, location and participants) while also examining whether repression attenuates such momentum. Using the Armed Conflict Location Event Data, this study employs two multilevel statistical methods to examine the factors that matter. First, the study examines the day-by-day factors that shape whether a protest will continue the next day. Second, the study examines the overall duration of events. The analyses find strong support that protests in capitals and urban areas, as well as protests featuring students, labour unions and professional organizations, last longer, while repression does truncate events.
How to Institutionalize Public Humanities Projects
Authors: Powers Peter Kerry 
Published: January 2025

Abstract
Public Humanities projects notoriously begin with the bootstrapping commitment of one or two long-suffering and visionary individuals. If they can make it past the turbulent narrows of their beginnings, they often only endure through unrecognized and little-rewarded labor. Gatherings of public humanists can be exercises in commiseration. When you determine that you have enough funding to last one more year, celebration is in order. Such travails naturally lead to the question of how public humanities programs can move beyond being nice extras to become more central to the concerns of our home institutions. How, in short, can the work of public humanists be institutionalized and become part of the everyday humdrum of academic life rather than the desperate scrabbling of the righteous, committed, frantic, and overtired?
The Cost of Political Action Committee Funding: Evidence on Political Action Committee Funding Refusal Across Candidate Race and Gender
Authors: Dudley Jennifer S. K. , Neff Olivia T. 
Published: January 2025

Abstract
Research on campaign finance suggests that Americans prefer candidates who are not funded by Political Action Committees (PACs). However, prior research has not examined how perceptions of a candidate who is PAC-funded vs. PAC-free might differ for racial minority and female candidates compared to White, male candidates. Using experimental vignettes, we test the causal impact of PAC funding, race, and gender on voter perceptions of the candidate. We find that refusing PAC funds, for example, is associated with appearing more ethical and more likely to work for voters’ interests over special interests, less corrupt, and more capable of winning elections. However, we show that race, more than gender, interacts with PAC funding to impact voter perceptions. We find that White female and male candidates benefit the most from PAC refusal. While Black female and male candidates receive little or no significant change in perceptions, Black PAC-funded candidates are perceived favorably compared to White PAC-funded candidates. Our results have implications for White and Black political candidates considering their funding strategies. Additionally, we contribute to existing literature by showing that refusing PAC funds status does not signal the same qualities for all candidates.
Indigenous Autonomy in Latin America: The Impact of the Indigenous Rights Revolution on the Study of Politics
Authors: Velasco Marcela , Kline Curtis 
Published: January 2025

Abstract
This paper asserts that critiques of political science for neglecting Indigenous politics highlight a critical gap that risks overlooking significant conceptual and practical innovations. It emphasizes how Indigenous autonomy claims challenge traditional notions of sovereignty. Scholars of Indigenous politics in Latin America, publishing in area studies journals, provide essential insights into these autonomy claims and contribute valuable perspectives to the discipline. We identify rigorous scholarly work in English language, peer-reviewed journals exploring Indigenous autonomy, conceptualizing it as a multifaceted notion that encompasses political visions, practices, and social movement agendas. Through a comprehensive meta-analysis of literature in Latin American area studies, we argue that this field offers four fundamental insights. First, Indigenous peoples deploy diverse strategies to assert their rights, positioning themselves as active citizens and political agents rather than passive groups. Second, the emergence of multicultural institutions that integrate individual and collective rights is fundamentally reshaping politics and citizenship, leading to innovative governance structures. Third, accumulation by dispossession remains a crucial driver of wealth creation, severely undermining Indigenous autonomy and degrading their environments. Finally, a renewed emphasis on Indigenous territorial autonomy decisively challenges conventional views of state sovereignty, as Indigenous peoples assert territorial and nonterritorial rights.
