AbstractBackgroundThe influence of prolonged intermittent Pringle maneuver (IPM) on post‐hepatectomy liver failure (PHLF) remains unclear. We evaluated the impact of the prolonged IPM on PHLF in patients undergoing open and laparoscopic hepatectomy.MethodsWe retrospectively included 546 patients who underwent hepatectomy using IPM. The patients were divided into open (n = 294) and laparoscopic (n = 252) groups. Odds ratios for PHLF occurrence were estimated in each group according to cumulative Pringle time (CPT). The cut‐off value was set at CPT of 120 min. Risk factors for PHLF were evaluated in the open and laparoscopic groups. Additionally, we analyzed the post‐operative outcomes in the open and laparoscopic groups with CPT ≥ 120 min and performed propensity score matching analysis based on PFLF‐associated factors.ResultsIn the open group, the risk of PHLF increased as CPT increased, particularly after 120 min. However, in the laparoscopic group, PHLF did not occur at less than 60 min, and the risk of PHLF was not significantly different at more than 60 min. Multivariate analysis identified CPT ≥ 120 min as an independent risk factor for PHLF in the open group (p < 0.001), but not in the laparoscopic group. Propensity score matching analysis showed that the PHLF rate was significantly lower in the laparoscopic group with CPT ≥ 120 min (p = 0.027). The post‐operative transaminase levels were significantly lower in the laparoscopic group with CPT ≥ 120 min.ConclusionsLaparoscopic hepatectomy may cause less PHLF with prolonged IPM compared with open hepatectomy.

AbstractLaser-induced breakdown spectroscopy (LIBS) is an emerging technique in geochemistry that allows rapid in-situ analysis of the elemental composition and concentration of minerals by laser ablation of the material surface and measurement of the light emitted by the resulting plasma. However, this type of application is still under development for geochemical analyses. Indeed, it is still difficult to know how minerals are ablated under laser pulses in the context of LIBS geochemical analysis using a high-power Q-switched Nd:YAG laser operating at 1064 nm with pulse durations on the order of nanoseconds. Important questions remain unanswered regarding the volume sampled by the laser beam on the minerals to be analyzed, as well as the plasmas induced by the laser on the minerals in air at atmospheric pressure. The objective of this work is to provide insight into laser-mineral interactions within the framework of LIBS geochemical analysis of ore samples with emphasis on the characterization of plasmas and laser ablation craters under ambient air at atmospheric pressure. We study the crater morphology in the three main phases of a palladium ore fragment (Lac des Iles mine, Canada), namely plagioclase feldspar, amphibole and sulfides [Mohamed et al., Geostand Geoanal Res 45:539, (2021)] We performed four series of laser shots (50, 250, 500 and 1000 shots) in the three mineral phases and characterized the morphology of the craters obtained by scanning electron microscopy and optical coherence tomography. It turns out that laser ablation is most effective in plagioclase, presumably due to its lower thermal conductivity. In addition, the temperature and electron density of the plasma were determined for each phase from the iron and nickel lines of LIBS spectra taken 4 µs after the laser shots. They are between 6300 and 8600 °C and about 2 × 1017 cm−3, respectively.
Introducing the Food Value Framework (FVF) to empower transdisciplinary research and unite stakeholders in their efforts of building a sustainable global food system
Authors: Brumm Alexander , Fukushi Kensuke 
Published: October 2023

AbstractThe global food system provides numerous benefits to humanity but also faces critical sustainability challenges with respective costs often burdened by society. As these costs are not sufficiently represented in market prices, increasing monetization efforts of externalities aim to reveal such hidden costs. However, monetary evaluation approaches have limitations such as conformity or including arguably unmonetizable impacts. Given that food production and consumption have been deeply embedded in human culture and behavior throughout millennia, systemic change is generally slow and precarious to enforce externally, especially given its existential role for daily survival. Rather than imposing relatively recent sustainability challenges, such as climate change, onto food systems, we hence suggest incorporating them into a core natural driver of human behavior: values. The objective of this research is to create a framework that can holistically address values associated with food in order to guide and unite stakeholders along the food value chain. Based on this human-centered bottom-up approach, empirical relevance of a respective framework to successfully translate into and guide sustainability efforts should be increased. We therefore combined established approaches of monetary accounting with a psychosocial perspective on basic human values and ethics to derive the Food Value Framework (FVF). We conclude that the FVF could address shortcomings of current evaluation methods and serve as a common foundation to empower transdisciplinary research, value-based policy-making, transparent production, and responsible consumption across the food value chain.
Multilevel asymmetric coupler MAC field rotator for LP11 mode in few mode fiber
Authors: El-Sabban Salwa , Khalil Diaa 
Published: October 2023

AbstractIn this work, we present a new design for an integrated optical field rotator for the mode LP11a to the mode LP11b and vice versa using planar Silica over silicon technology. The structure is designed using a Multilayer Asymmetric Coupler. The coupling efficiency of the coupler could be as high as 99% when its length is about 1 mm. For a shorter coupler of length 550 microns and a coupling efficiency of 91%, a complete structure is designed to couple 2 few mode fibers of diameters 15.4 microns through an inverted taper from one side and a Y junction with two inverted tapers from the other side. The fiber to fiber insertion loss of the proposed structure is less than 3 dB over about 190 nm spectral range around 1550 nm. The 3 dB bandwidth of the structure is greater than 360 nm as demonstrated by the Beam Propagation Method BPM simulation.
Distribution for Non Symmetric Position Operators on the Free Toy Fock Space and Its Approximation on the Full Fock Space
Authors: Oussi Lahcen 
Published: October 2023

AbstractIn this paper, we investigate the “Poisson-type” limit theorem with respect to the vacuum state of a family of partial sums of non-symmetric position operators under an appropriate scaling on the free toy Fock space. We give a formula for the vacuum moment in relation with the combinatorics of non-crossing partitions. We show that the asymptotic measure associated to the limit of the partial sums of these operators is the free Meixner law with an atomic and an absolutely continuous part, whereas the probability distribution of any single operator is the two-point probability. The approximation of such operators on the full Fock space is given.
Production of High Surface Area Activated Carbon from Peanut Shell by Chemical Activation with Zinc Chloride: Optimisation and Characterization
Authors: Fletcher Ashleigh , Somorin Tosin , Aladeokin Oluwagbemi 
Published: October 2023

AbstractThe potential of peanut shell as a precursor to produce activated carbon by chemical activation with ZnCl2, and the effect of activation variables were investigated using response surface methodology. Activation variables examined were temperature, hold time and impregnation ratio; among these, impregnation ratio and temperature were found to most affect the final characteristics of the produced activated carbon. The activation process was mapped, using design of experiments, and the optimum activation conditions were found to be a temperature of 485 °C, with a hold time of 15 min and an impregnation ratio of 1.7. Under the optimised conditions, an activated carbon with a relatively high surface area of ~ 1700 m2/g was produced, at a yield of 47%. Moreover, the carbon exhibited a relatively high density, ranging from 1.455 g/cm3 to 1.750 g/cm3, as well as a low ash content below 1% and a high fixed carbon content above 86%. SEM analysis and FTIR characterisation revealed the heterogenous nature of the produced carbon materials. The developed materials, with potential as adsorbents, removed up to 99.8% of a target dye (methyl orange) depending on their available surface area. Hence, through the insights gained, an optimised carbon is produced, demonstrating the potential to tailor activated carbon materials produced from waste biomass.

Published: October 2023

Abstract
Background
Latino men who have sex with men (MSM) experience disproportionately high rates of HIV diagnoses in the United States. Pre-exposure prophylaxis (PrEP) use is critical to reduce this inequity, but PrEP awareness, access, and use are low among Latino MSM. This study aims to describe patterns of PrEP persistence and discontinuation among predominately Latino MSM accessing PrEP in a federally qualified health center (FQHC) in El Paso, Texas.

Methods
This retrospective cohort comprised individuals who were eligible for PrEP at a FQHC in El Paso, Texas, between January 30, 2019, and August 15, 2021. We defined hierarchical categories of PrEP use and discontinuation, which was defined as more than 120 days between PrEP visits. We used Kaplan–Meier survival plots to estimate median time to first PrEP discontinuation.

Results
There were 292 patients evaluated for PrEP; 91% were Latino. The majority of PrEP patients (70%, 205/292) experienced any PrEP discontinuation, and the median time to first PrEP discontinuation was 202 days (95% CI: 179–266). The proportion of patients who remained on PrEP at 3 months after initiation was 82% (95% CI: 76%, 87%) and at 6 months after initiation was 55% (95% CI: 46%, 62%).

Conclusion
While 3-month PrEP retention was high in this predominately Latino MSM patient population, PrEP discontinuation was common. Interventions that enhance longer-term persistence and support for restarting PrEP are needed to reduce the persistent ethnoracial disparities in HIV incidence.

AbstractPedestrian re-identification (re-ID) has gained considerable attention as a challenging research area in smart cities. Its applications span diverse domains, including intelligent transportation, public security, new retail, and the integration of face re-ID technology. The rapid progress in deep learning techniques, coupled with the availability of large-scale pedestrian datasets, has led to remarkable advancements in pedestrian re-ID. In this paper, we begin the study by summarising the key datasets and standard evaluation methodologies for pedestrian re-ID. Second, we look into pedestrian re-ID methods that are based on object re-ID, loss functions, research directions, weakly supervised classification, and various application scenarios. Moreover, we assess and display different re-ID approaches from deep learning perspectives. Finally, several challenges and future directions for pedestrian re-ID development are discussed. By providing a holistic perspective on this topic, this research serves as a valuable resource for researchers and practitioners, enabling further advancements in pedestrian re-ID within smart city environments.
Rethinking Informal Economy Resilience during Crisis: Experience from COVID-19 Pandemic
Authors: Aditya Bagas , Amri Ikhwan 
Published: October 2023

AbstractThe COVID-19 pandemic has disrupted the public health system and socioeconomic sector, one of the worst being the impacts on the informal economy. Despite their past survival, the current pandemic-induced crisis has cast doubt on informal economy resilience. This study aims to capture the informal economy resilience facing the unprecedented economic crisis triggered by the COVID-19 pandemic. We reviewed 42 selected peer-reviewed journal articles to synthesise a general concept of informal economy resilience during pandemic-induced crisis. We found that strict lockdown during a pandemic becomes the main driver that exacerbates the vulnerability of informal economy. The impacts are spatiotemporally varied, different within the group, and have multilevel characteristics (from individual to society). This vulnerable condition has triggered the informal economy to conduct several coping mechanisms to face economic disadvantages. Both individual coping mechanisms and government intervention have altered the informal economy's resilience throughout time. The current combination of defense mechanisms results in four possibilities: bounce back better, bounce back, recover but worsen, and collapse. This review offers valuable insights into the appropriate actions that governments should undertake in response to economic downturns resulting from pandemics. It highlights the importance of considering vulnerable groups when formulating policy during a crisis.
Evolution of Inequality in Nigeria: a Tale of Falling Inequality, Rising Poverty, and Regional Heterogeneity
Authors: Odozi John Chiwuzulum , Uwaifo Oyelere Ruth 
Published: October 2023

AbstractRecent research on Nigeria indicates declining income inequality. In contrast, anecdotal evidence suggests that only the upper class has benefited from economic growth in Nigeria over time. The disconnect between these findings and anecdotal evidence, and the limitation in how inequality was estimated in the past literature are the motivation for our research. First, we consider if inequality decreased in Nigeria between 2010 and 2018. We then examine how changes in inequality relate to changes in consumption and poverty. In addition, we examine whether there has been convergence in inequality and consumption across geopolitical regions over this period? Leveraging data from the four waves of the Nigeria General Household Panel Survey (GHS) and carefully measuring inequality in consumption expenditure using Gini, our results suggest that between 2010 and 2018, inequality decreased and median consumption expenditure increased. At the same time, poverty incidence and severity increased precipitously. Our findings also suggest convergence across regions over time in estimated within region Gini. In contrast, we find evidence of divergence across regions over time in median households’ consumption.
Surgical Residents´ Results Seem to be Non-Inferior Comparing to More Experienced Surgeons in Femoral Neck Fracture Osteosynthesis

Published: October 2023

Abstract
Purpose of the Study
Femoral neck fracture osteosynthesis is usually performed by using dynamic hip screw (DHS) or multiple parallel cannulated screws (MCS). In orthopedic surgery training, certain hip fractures are one of the most common operations performed by residents. It has been questioned, whether residents can provide as safe treatment and patient outcomes as those of more experienced surgeons. The aim of this study was to evaluate the effect of surgical experience on risk of complications by comparing the surgical performance and clinical outcomes in femoral neck osteosyntheses between surgical residents and orthopaedic surgeons.

Methods
All patients with femoral neck fracture admitted to Helsinki and Uusimaa Hospital District (HUS) Hyvinkää Hospital from 2011 to 2016 were collected as research material. 88 hip fractures (87 patients) treated with DHS or MCS osteosyntheses were included in this study. The patients were divided into 2 groups, based on the surgeon’s experience: an orthopedic surgeon group (n = 68) and a surgical resident group (n = 20). All data from complications, reoperations, and the duration of operations were collected.

Results
There was no significant difference in characteristics of operated patients between orthopaedics and residents group. There was no significant difference in complications or re-operations between groups (p = 0.4, p = 0.2). Surgical residents had statistically longer surgical time (mean 76 min, 95% CI 62.92 min, mean 46 min, 95% Cl 42.51 min; p-value < 0.001). Still surgical time was not a risk factor for complication (p-value 0.5).

Conclusion
Our results show that surgical residents´ outcomes in femoral neck fracture osteosynthesis seem to be as favorable as those of orthopedic surgeons; the operations just last slightly longer.
Adaptability of everyday planning in urban design practices: self-organization and spontaneous action analysis of Galataport, Istanbul

Published: October 2023

AbstractCities are information systems by its social and physical components. The data of these components create a wider picture in urban texture than it was designed by planners and designer in urban practices. The idea of collecting the data and composing models of spontaneous actions in urban simulations can add different dimensions to planning ideas in social terms and spatial texture. The issue is to find out how these components can be better related with each other to let citizens be urban planners as well up to some level, and what level that would be. The aim of the project is to bring back the social impact of the whole city as linking the hubs of Karaköy and Kabataş through the waterfront, also reawakening the collective memory of the port, by preserving the texture of warehouses form Ottoman Empire. The final outcome would be understanding how effectively project would be able to create the dynamics that have been proposed, and whether there have been other spontaneous actions thought the designed area.

Published: October 2023

AbstractThis study compared the extent to which COVID-19 impacted travel demand of bike-sharing and taxi in New York City, and further explored how the changes in travel demand were associated with the built environment through four typical regression models, namely, least squares (OLS) regression, geographically weighted regression (GWR), temporally weighted regression (TWR), and geographically and temporally weighted regression (GTWR) models. In particular, this study looked at two phases: the lockdown phase (during which travel demand decreased dramatically) and initial recovery phase (during which travel demand started to increase). The results suggested that 1) GTWR performed better than the other three model types; 2) shared bike ridership rebounded much more significantly during the recovery phase than taxi ridership; 3) Commercial Point of Interest (POI) was positively associated with the change of ridership in both lockdown and recovery phases.
Unlocking the sustainability of medium enterprises: A framework for reducing cognitive biases in sustainable performance management
Authors: Cristofaro Matteo , Giardino Pier Luigi , Camilli Riccardo , Hristov Ivo 
Published: October 2023

AbstractMedium Enterprises (MEs) are significant contributors to global economic development. Integrating sustainability practices in their business can support MEs worldwide to become more sustainable, improving companies’ performance and stakeholders’ expectations. Nevertheless, few MEs adopt sustainable practices. Following Behavioral Decision Theory and Behavioral Strategy literature, we argue that this can be associated with their managers’ decision-making processes – apart from not possessing considerable resources like large companies. Via a mixed-method research design involving 277 Italian ME managers, we investigate the cognitive biases that hinder the development of a sustainable performance management system (SPMS) in MEs. We found the most prominent biases influencing SPMS development. Then, we developed a ‘SPMS de-biasing funnel’ framework. We propose some corrective actions to reduce the impact of the most critical cognitive biases that influence SPMS development, allowing related beneficial potential outcomes.
International law, climate change and the Antarctic Treaty System: re-contemplating governance questions apropos of the mounting challenges
Authors: Madani Zia , Shibata Akiho 
Published: October 2023

AbstractMore than 60 years since it entered into force in 1961, the Antarctic Treaty is experiencing significant challenges. These challenges also affect its associated instruments known as the Antarctic Treaty System (ATS). These are mostly external dynamics that are increasingly challenging the ATS from outside of the Antarctic region. They encompass a spectrum of issues relating to global legal regimes and to what extent they are applicable in the Antarctic context. Climate change appears to be the most significant of these challenges, as the tangible planetary impacts of global warming and the perception of its urgency and seriousness by states have prompted additional challenges to the ATS. The physical changes that continue to be scientifically unveiled in the Antarctic are manifesting severe impacts on a planetary scale, and this fact has underscored the need for broader and more rapid international engagement within the Antarctic governance discourse. Nevertheless, the existing decision-making mechanisms compounded by the adversarial atmosphere within the ATS due to external factors have become challenges of themselves. Such challenges call for the re-contemplation and reassessment of the legal regime of the Antarctic in general, and the ATS in particular, to find ways forward for an otherwise historically effective international legal system. This paper utilizes both scientific and legal lenses to underscore the urgent need to achieve better communication between the ATS generally, the Antarctic Treaty Consultative Meetings specifically and the UN Framework Convention on Climate Change and Intergovernmental Panel on Climate Change regimes and to overcome the multiple barriers that stand in the way of achieving that objective.
