Prediction of wear volume and friction coefficients of SS304 alloy using grey taguchi-based response surface methodology
Authors: Ponnuswamy Palanikumar , Manoharan Madhanagopal 
Published: April 2024

Abstract
The present investigation is centered on examining the tribological characteristics within a pin-on-disk configuration resembling a cylinder on a flat contact surface. The pin, constructed from Stainless Steel 304 alloy, underwent sliding experiments under varying speeds (1, 2, and 3 m s−1) and normal loads (10, 15, and 20 N) across track diameters of 60 and 120 mm. The experiments aimed to mitigate wear and friction in movable components, thus conducted for up to 2000 s in the experimental setup without any lubrication. Observations of the coefficients of friction stabilization and wear rate were made by manipulating the input parameters to anticipate the failure range. Higher coefficients of friction and increased wear rates were noted at lower sliding speeds, with wear rates stabilizing at higher speeds. Interestingly, despite a higher coefficient of friction stabilization and wear rate at a 120 mm track diameter, wear decreased. Optical Microscopy studies were carried out to examine surface damage for all normal loads and sliding speeds using both 60 mm and 120 mm track diameters. Additionally, this study employs Grey Taguchi-based Response Surface Methodology (GT-RSM) to forecast and regulate wear and friction. The findings of this study have practical implications for industries such as automotive, aerospace, and others employing SS 304 alloys in their operational components.

Published: April 2024

Abstract

Purpose. The aim of this study is to determine the planar dose distribution of irregularly-shaped electron beams at their maximum dose depth (z
max) using the modied lateral build-up ratio (LBR) and curve-fitting methods. Methods. Circular and irregular cutouts were created using Cerrobend alloy for a 14 × 14 cm2 applicator. Percentage depth dose (PDD) at the standard source-surface-distance (SSD = 100 cm) and point dose at different SSD were measured for each cutout. Orthogonal profiles of the cutouts were measured at z
max. Data were collected for 6, 9, 12, and 15 MeV electron beam energies on a VERSA HDTM LINAC using the IBA Blue Phantom2 3D water phantom system. The planar dose distributions of the cutouts were also measured at z
max in solid water using EDR2 films. Results. The measured PDD curves were normalized to a normalization depth (d
0) of 1 mm. The lateral-buildup-ratio (LBR), lateral spread parameter (σ

R
(z)), and effective SSD (SSD

eff
) for each cutout were calculated using the PDD of the open applicator as the reference field. The modified LBR method was then employed to calculate the planar dose distribution of the irregular cutouts within the field at least 5 mm from the edge. A simple curve-fitting model was developed based on the profile shapes of the circular cutouts around the field edge. This model was used to calculate the planar dose distribution of the irregular cutouts in the region from 3 mm outside to 5 mm inside the field edge. Finally, the calculated planar dose distribution was compared with the film measurement. Conclusions. The planar dose distribution of electron therapy for irregular cutouts at z
max was calculated using the improved LBR method and a simple curve-fitting model. The calculated profiles were within 3% of the measured values. The gamma passing rate with a 3%/3 mm and 10% dose threshold was more than 96%.
Analysis of spin-squeezing generation in cavity-coupled atomic ensembles with continuous measurements
Authors: Caprotti A , Barbiero M , Tarallo M G , Genoni M G , Bertaina G 
Published: April 2024

Abstract
We analyze the generation of spin-squeezed states via coupling of three-level atoms to an optical cavity and continuous quantum measurement of the transmitted cavity field in order to monitor the evolution of the atomic ensemble. Using analytical treatment and microscopic simulations of the dynamics, we show that one can achieve significant spin squeezing, favorably scaling with the number of atoms N. However, contrary to some previous literature, we clarify that it is not possible to obtain Heisenberg scaling without the continuous feedback that is proposed in optimal approaches. In fact, in the adiabatic cavity removal approximation and large N limit, we find the scaling behavior

for the corresponding protocol duration. These results can be obtained only by considering the curvature of the Bloch sphere, since linearizing the collective spin operators tangentially to its equator yields inaccurate predictions. With full simulations, we characterize how spin-squeezing generation depends on the system parameters and departs from the bad cavity regime, by gradually mixing with cavity-filling dynamics until metrological advantage is lost. Finally, we discuss the relevance of this spin-squeezing protocol to state-of-the-art optical clocks.
Density functional theory beyond the Born–Oppenheimer approximation: exact mapping onto an electronically non-interacting Kohn–Sham molecule
Authors: Fromager Emmanuel , Lasorne Benjamin 
Published: April 2024

Abstract
This work presents an alternative, general, and in-principle exact extension of electronic Kohn–Sham density functional theory (KS-DFT) to the fully quantum-mechanical molecular problem. Unlike in existing multi-component or exact-factorization-based DFTs of electrons and nuclei, both nuclear and electronic densities are mapped onto a fictitious electronically non-interacting molecule (referred to as KS molecule), where the electrons still interact with the nuclei. Moreover, in the present molecular KS-DFT, no assumption is made about the mathematical form (exactly factorized or not) of the molecular wavefunction. By expanding the KS molecular wavefunction à la Born–Huang, we obtain a self-consistent set of ‘KS beyond Born–Oppenheimer’ electronic equations coupled to nuclear equations that describe nuclei interacting among themselves and with non-interacting electrons. An exact adiabatic connection formula is derived for the Hartree-exchange-correlation energy of the electrons within the molecule and, on that basis, a practical adiabatic density-functional approximation is proposed and discussed.
Learning a general model of single phase flow in complex 3D porous media
Authors: Santos Javier E , Marcato Agnese , Kang Qinjun , Mehana Mohamed , O’Malley Daniel , Viswanathan Hari , Lubbers Nicholas 
Published: April 2024

Abstract
Modeling effective transport properties of 3D porous media, such as permeability, at multiple scales is challenging as a result of the combined complexity of the pore structures and fluid physics—in particular, confinement effects which vary across the nanoscale to the microscale. While numerical simulation is possible, the computational cost is prohibitive for realistic domains, which are large and complex. Although machine learning (ML) models have been proposed to circumvent simulation, none so far has simultaneously accounted for heterogeneous 3D structures, fluid confinement effects, and multiple simulation resolutions. By utilizing numerous computer science techniques to improve the scalability of training, we have for the first time developed a general flow model that accounts for the pore-structure and corresponding physical phenomena at scales from Angstrom to the micrometer. Using synthetic computational domains for training, our ML model exhibits strong performance (R
2 = 0.9) when tested on extremely diverse real domains at multiple scales.
Targeting farmers’ heterogeneity to enrich climate change adaptation policy design: findings from northern Italy
Authors: Ricart Sandra , Gandolfi Claudio , Castelletti Andrea 
Published: April 2024

Abstract
With its scientifically proven effects and widespread acceptance, climate change stands as one of the most pressing and intricate challenges for society and economies. Farmers are on the frontline of managing climate change. Therefore, how they perceive and respond to climate change shapes their risk assessment and structures future resilience and adaptive capacity. Employing a bottom-up approach, we conducted 460 surveys randomly among farmers throughout the Lombardy region in northern Italy. A triple-loop approach considering climate change awareness, perceived impacts, and adaptation measures and barriers was implemented to characterize the potential heterogeneity of farmer behaviour and explore whether risk attitudes and adaptation actions differ between farmer profiles. We then profiled farmers through a clustering analysis. Four groups emerged, highlighting farmers’ adaptation preferences and risk attitudes: (1) cropping-adapted and isolated farmers, (2) cooperation-adapted and insecure farmers, (3) risk insurance-adapted and confident farmers, and (4) climate services-adapted and aware farmers. Although the groups vary in terms of farmers’ characterization and farming activities (e.g. young and highly educated vs. old and highly experienced farmers, rainfed vs. irrigated farms), similar patterns were observed regarding climate change awareness and perceived impacts—however, the contrast increased in terms of adaptation measures and barriers. Gaining a more comprehensive understanding of the diverse ways in which farmers assess risks and adapt can promote the transferability of bottom-up findings and inform the co-design of tailored and flexible adaptation instruments, minimizing the risk of maladaptation or ineffective transformation in the face of climate change.
Conclusion
Authors: Anderson Neal G , Piccinini Gualtiero 
Published: April 2024

Abstract
This Conclusion summarizes the arguments put forward in this book, places them in the broader context of accounts of physical computation and debates about pancomputationalism, and expands upon them. First, it recaps (i) how we classify computational descriptions of physical systems by their descriptive strength, (ii) what it means to accept descriptions of a given strength as adequate, and (iii) how this leads to our robust mapping account of implementation. Second, it reiterates how the robust mapping account rules out pancomputationalism while accommodating physical computing substrates—conventional and unconventional, artificial and natural—that bear genuine physical signatures of computation. Third, it places our robust mapping account in the context of previous accounts of physical computation. Fourth, it highlights common notions of biological and artifact computation and, drawing from the present work, sketches a single account under which they are unified. Fifth and finally, it summarizes key takeaways from this work.
cancercelllines.org—a novel resource for genomic variants in cancer cell lines
Authors: Paloots Rahel , Baudis Michael 
Published: April 2024

Abstract
Cancer cell lines are an important component in biological and medical research, enabling studies of cellular mechanisms as well as the development and testing of pharmaceuticals. Genomic alterations in cancer cell lines are widely studied as models for oncogenetic events and are represented in a wide range of primary resources. We have created a comprehensive, curated knowledge resource—cancercelllines.org—with the aim to enable easy access to genomic profiling data in cancer cell lines, curated from a variety of resources and integrating both copy number and single nucleotide variants data. We have gathered over 5600 copy number profiles as well as single nucleotide variant annotations for 16 000 cell lines and provide these data with mappings to the GRCh38 reference genome. Both genomic variations and associated curated metadata can be queried through the GA4GH Beacon v2 Application Programming Interface (API) and a graphical user interface with extensive data retrieval enabled using GA4GH data schemas under a permissive licensing scheme.

Educational Inequalities in Dual-Function Life Expectancy
Authors: Bauldry Shawn , Thomas Patricia A , Sauerteig-Rolston Madison R , Ferraro Kenneth F 
Published: April 2024

Abstract

Objectives
This study investigates educational inequalities in dual functionality, a new concept that captures a combination of physical and cognitive functioning, both of which are important for independent living and quality of life.

Methods
Using data from the Health and Retirement Study and the National Health Interview Survey Linked Mortality Files, we define a measure of dual functionality based on the absence of limitations in activities of daily living and dementia. We estimate age-graded dual-function rates among adults 65+ and age-65 dual-function life expectancy across levels of education stratified by gender.

Results
In their mid-60s, 67% of women with less than a high school degree manifest dual functionality as compared with over 90% of women with at least a 4-year college degree. A similar pattern holds among men. These education-based gaps in dual functionality remain across later life, even as dual-function rates decline at older ages. Lower dual-function rates among older adults with less education translate into inequalities of 6.7 and 7.3 years in age-65 dual-function life expectancy between men and women, respectively, with at least a 4-year college degree compared to their counterparts with less than a high school degree.

Discussion
Older adults, particularly women, with less than a high school degree are estimated to live a smaller percentage of their remaining years with dual functionality compared with older adults with at least a college degree. These inequalities have implications for the distribution of caregiving resources of individuals, family members, and the broader healthcare community.

Published: April 2024

Abstract

OBJECTIVES
Aortic arch or aortic root replacement is not performed in all cases of acute type A aortic dissection (ATAD), and a second aortic procedure will become necessary over time for some patients. Indications and outcomes, of second aortic procedures have not been studied extensively.

METHODS
Characteristics and in-hospital outcomes of all patients undergoing surgical repair for type A acute aortic dissection were analysed and patients needing second aortic procedure during follow-up were identified. The latter group was divided in 2 subgroups: on-pump includes patients operated on using cardiopulmonary bypass and off-pump without cardiopulmonary bypass.

RESULTS
A total of 638 patients underwent surgery for ATAD; 8% required a second aortic procedure. The most frequent indication for the second aortic procedure was dehiscence of suture lines (44%), followed by arch dilatation (24%). In-hospital mortality was 12%. Isolated ascending aorta replacement at the first surgery was associated with higher incidence of second aortic procedure (P = 0.006). Most patients in the on-pump group underwent a proximal reoperation (75%), with a mortality rate of 14.2%. In-hospital mortality of patients in the off-pump group was 7.7%. Long-term survival analysis showed no difference between groups (P = 0,526), Off-pump patients have greater likelihood of a second intervention during follow-up (P  = 0.004).

CONCLUSIONS
Extended aortic root surgery and customized aortic arch repair in ATAD could be reasonable to reduce the incidence and mortality of high-risk second aortic procedures.
Interpersonal Commitment: The Hidden Power of Face-to-Face Diplomacy
Authors: Heimann Gadi , Kampf Zohar 
Published: April 2024

Abstract
This article argues that interpersonal commitment is statespersons’ most highly coveted aim, the greatest benefit that interpersonal relations can yield in diplomacy. Accordingly, statespersons employ a range of relational practices in encounters with counterparts, seeking to create and harness commitment that will advance professional aims. We argue that statespersons can follow one of two paths to generate commitment: (1) creating feelings of gratitude and providing help that makes a counterpart feel indebted; or (2) cultivating friendly relations. Both demand the successful implementation of relational practices. On the basis of thirty semistructured interviews with past and present senior Israeli statespersons and an analysis of fifteen autobiographies written by senior Israeli diplomats and political figures, we demonstrate to what extent statespersons acknowledge the importance of interpersonal commitment and its ramifications; identify the relational practices that statespersons employ to elicit commitment from a counterpart; and discuss the conditions that facilitate the emergence of such a commitment. We conclude by discussing the differences between thin and thick interpersonal commitments and underlining the importance of interpersonal relations in diplomacy.
Are predatory mites effective as biological control agents to suppress Oligonychus ilicis (Acari: Tetranychidae) in blueberry plantings?
Authors: Marucci Rosangela C , Ruber Stella E , Pec Marvin , Liburd Oscar E 
Published: April 2024

Abstract
Southern red mite, Oligonychus ilicis McGregor (Acari: Tetranychidae), is an important polyphagous spider mite pest that causes economic damage to many ornamentals, coffee, and fruit crops. Blueberry growers in the Southeastern United States, including Florida and Georgia, have experienced severe losses due to outbreaks of O. ilicis. Predatory mites are an important management tool used for controlling spider mites; however, predators have not been studied and successfully evaluated in blueberry systems. Amblyseius swirskii Athias-Henriot, Phytoseiulus persimilis Athias-Henriot, and Neoseiulus californicus (McGregor) (Acari: Phytoseiidae) are among the most economically important arthropod agents used in augmentative biological control worldwide. To evaluate the potential of these 3 commercially available predatory mites for use in blueberry plantings, we conducted experiments under controlled laboratory conditions and in the greenhouse. In preliminary laboratory experiments, P. persimilis and N. californicus significantly reduced the number of O. ilicis motile stages below those found in the untreated control, indicating the potential for these 2 predatory mite species to suppress O. ilicis populations. Amblyseius swirskii did not perform well controlling O. ilicis motiles in the laboratory. Under greenhouse conditions, N. californicus and P. persimilis significantly reduced the number of eggs after 7 days of release and the number of motile stages after 14 days of release. This is the first report of using phytoseiid mites to suppress O. ilicis in blueberry systems in the United States. Further studies on predator behavior, feeding preferences, and acaricide compatibility with predators are required to investigate the possibility of using P. persimilis, and N. californicus as biological control agents of O. ilicis in blueberry systems.
Effects of mowing on the arthropod community in grass buffers and adjacent crop fields
Authors: Dively Galen P , Hooks Cerruti R R 
Published: April 2024

Abstract
Grass buffers are commonly planted along crop borders to filter nutrient and pesticide runoff. These buffers also provide food and shelter for beneficial and herbivorous arthropods and can serve as corridors for their movement into neighboring crops. Mowing is a common maintenance practice to control woody plants in these buffers. Field experiments were conducted to determine whether mowing influences the movement of arthropods into neighboring soybean plantings (Glycine max L) and impacts their abundance in corn (Zea mays var. indentata) the following spring. Results showed that mowing had varying effects on the abundance of herbivores, saprovores, parasitoids, and predators, particularly in the grass buffers. Aerially active arthropods in the plant canopy were more adversely affected by mowing than surface-dwelling arthropods. Mowing significantly reduced grasshopper (Orthoptera: Acrididae) density in the buffers, but did not trigger their movement into adjoining soybean fields. Parasitoids, predators, and thrips (Thysanoptera: Thripidae) were dissimilarly affected by mowing, and their responses were influenced by grass type. Altogether, these findings indicate that mowing did not cause notable movement of arthropods from grass buffers into adjoining crops and had minimal effects on the community of beneficial arthropods the following spring. Also, there were no differences in the level of insect feeding injury in crop fields next to mowed and unmowed buffers.
‘Objects bring us traces of life’
Authors: Davoli Silvia 
Published: April 2024

Abstract
This essay explores the profound impact of Giambattista Vico’s philosophy of history on two nineteenth-century museographic projects.1 The two collections are Michele Cavaleri’s museum in Milan and Enrico Cernuschi’s museum in Paris. Vico’s emphasis on historical knowledge as the key to understanding human civilization, and his unique approach to the aesthetics of primitive cultures influenced scholars and collectors interested in the origins of art and architecture throughout the eighteenth and nineteenth centuries. I first discuss the Milanese school of philosophy, which played a pivotal role in re-evaluating Vico’s contributions, and its impact on both Cavaleri and Cernuschi. The two collectors, deeply rooted in Milan’s intellectual circles, incorporated Vico’s ideas into their museums, which aimed to showcase the interconnectedness of art, culture and history. Their endeavours to advance the contextual understanding of works of art are discussed, shedding new light on the influence of Vico’s anthropological historicism on nineteenth-century thought and culture.
Can you patent the sun? Towards a sui generis inclusive right to manage the relationship between intellectual property and Commons
Authors: Cifrodelli Gabriele 
Published: April 2024

Abstract
This paper, by adopting the Covid-19 vaccine as a case study, argues that some pharmaceutical drugs should be considered as Commons, ie goods that are managed and owned by the public at large, and not as private property—exclusivity—of pharmaceutical companies. The reasons of such a strong argument are, on the one side, the conspicuous public-funding contribution to develop Covid-19 vaccines and other essential life-saving treatments, and, on the other side, the search for a human and equity-oriented Global Health Security. It is true that, from a legal perspective, vaccines can be patented, leading to questionable practices in the pharmaceutical industry, such as patent thickets. However, an alternative and fairer path, which would result in the theorization of a Commons for the vaccine, can be pursued. In particular, the actual types of Commons in the IP law field—the public domain, exceptions/limitations to patents and open innovation instruments such as IP pledges—present some issues in relation to enforceability. By forwarding the concept of ‘negative spaces’ to the patent realm, these spaces should not only claim to not enforce IP but also be able to ‘enforce that non-enforcement’. Therefore, this paper, by building on the work of the author Dusollier, advances the idea that from the inclusivity, which is the typical feature of every Commons, a sui generis inclusive right can be envisaged and applied in the context of the vaccine, by rethinking the relationship between IP and Commons.
