AbstractIntroductionPeople with eating disorders (EDs) frequently report self‐injurious thoughts and behaviors (SITBs). We aimed to replicate and extend findings demonstrating greater interoceptive deficits according to SITB severity. We predicted that interoceptive deficits would be greater among people with versus without lifetime SITBs and among those with multiple suicide attempts compared with single attempts or nonsuicidal self‐injury. We also predicted that interoception would be increasingly impaired with greater current suicidality severity.MethodAdults (N = 118) seeking ED treatment reported current and lifetime SITBs upon admission to treatment. We used planned contrasts to compare interoceptive deficits (self‐reported using the Eating Disorders Inventory) by SITB and current suicidality groups (assessed by self‐report and clinical interview).ResultsInteroceptive deficits were greater among people with any SITB history compared to those without. People with multiple suicide attempts did not differ in interoceptive deficits from those with single attempts or only nonsuicidal self‐injury. Interoceptive deficits were elevated among those with any current suicidality compared to those with no suicidal symptoms; interoceptive deficits did not differ according to severity of suicidality.ConclusionAmong those with EDs, interoceptive deficits are elevated among those with concurrent SITBs. Interventions aimed at improving interoception may reduce the risk for SITBs.

AbstractRemnant fabrics inherited from mid‐ridge play a key role in variations of plate deformation, hydration and seismicity along subduction zones. However, the quantitative relationships between the orientation of these remnant faults, plate bending and seismic activity at subduction zones still remain unclear. Here, we investigated the flexure of the Alaska subducting plate and assessed the relations between plate flexural curvatures, trench–fabric angle and seismicity. The results show that the flexural curvature and seismicity have nearly linear relationships with the trench–fabric angle. We find that remnant faults are more likely to be reactivated by plate bending at low trench–fabric angle region, causing greater plate deformation, hydration, weakening and seismicity. Plate weakening in turn promotes flexural bending curvature, resulting in higher degree of fracture and more earthquakes. However, at the high trench–fabric angle region, it is inclined to form new trench‐parallel bending faults that have smaller bending curvature and less seismicity.

AbstractAimsA cross‐sectional study was carried out to assess the seroprevalence and risk factors associated with Trichinella spp. exposure in wild boar and Iberian domestic pigs from Mediterranean ecosystems of southwestern Spain.Methods and ResultsSerum samples from 1360 wild boar and 439 Iberian domestic pigs were obtained during 2015–2020, from regions where Iberian pigs are raised under extensive conditions, hence sharing habitat with wild boar. Seropositivity was found in 7.4% (100/1360; 95% CI: 6.1–8.9) of the wild boar analysed. In this species, the individual seroprevalence ranged from 3.6% (8/223) (hunting season 2016–2017) to 11.4% (37/326) (2018–2019). A significant higher seropositivity was observed during the hunting season 2018–2019 (p < 0.009: OR = 3.07; 95% CI = 1.32–7.18) and one statistically significant cluster was detected within the studied area, in south central Andalusia [Relative Risk (RR) = 2.9; p = 0.037]. Females showed a significantly higher seroprevalence than males (8.7% vs. 5.8%) (p < 0.001: OR = 1.58; 95% CI = 1.08–2.32). No seropositivity to Trichinella spp. was detected in Iberian domestic pigs (0.0%; 95% CI: 0.0–0.9).ConclusionsAlthough wild boar play an important role as a reservoir of Trichinella sp. in the Mediterranean ecosystems of southwestern Spain, our results suggest that the wild boar production system does not seem to pose a risk of Trichinella exposure to domestic pigs, despite sharing habitats in these ecosystems.
Decommissioning of the MAU Facility at La Hague: How a Good Association of Milling Tools Can Facilitate the Decommissioning of Nuclear Areas?

Abstract
It is often the case, in reprocessing facilities and waste repositories, that surface decontamination requires mechanical milling techniques on concrete, cement or brick surfaces (coated or uncoated). Integrated and compliant techniques for the efficient milling of these surfaces are in demand in a growing decommissioning sector, due to a large number of these scenarios which present challenging geometries.
This is the case for the dismantling of the MAU building which is part of Orano La Hague’s UP2 400 fuel recycling plant.
Mechanical processes proved to work since facilities are being decommissioned; however, the capability of such applications to fulfill the requirement in term of economics, techniques and environment/social need to be confirmed. Particularly, the speed rate, the strenuous working conditions, the dust’s capture’s efficiency, the possibility to obtain a final surface state that allows final surface radiological measurements have often been criticized in the various feedbacks from the work sites.
To improve clean-up operations on dismantling sites, ORANO DS collaborated with the company Astillo. Specialized in the design and manufacture of machine and tool for the surface removal of pollutants, Astillo benefits from experience in the surface treatment’s sector.
Particularly, the possibility to work with no detectable increase in airborne exposures (efficient vacuum attachments), the guarantee that all workers’ exposition to dose is kept as low as possible (semi-remote operation), the potential to accommodate a wide range of surfaces geometry and types by adaptable tools will be described.

Abstract
The aims of this article is to estimate the dose of gamma-emitting radionuclides resulting from the atmospheric release of radioactive material Iodine-131 from an accident at two nuclear facilities simultaneously. HotSpot Health Physics Codes 3.1.2 software was utilized for this purpose. Monitoring the dispersion of Iodine-131 in the atmosphere after an accident in nuclear installations is essential for nuclear safety. This monitoring involves not only the amount of material that will be released, but also understanding its dispersion in the atmosphere and the areas that may be affected. The data collected form such monitoring is extremely relevant to assess accumulation, exposure and its consequences, as well as in making decision about mitigation requirements in contaminated sites. In this article, data from a hypothetical Loss of Coolant Accident (LOCA) at two Pressurized Water Reactor (PWR) nuclear power plants were used in order to study the behavior of radioactive plumes in the event of radiation release into the atmosphere of both plants. The results show that in most of the tests carried out, the Gaussian model used for plume modeling assumed different values and fluctuations, directly related to the atmospheric stability class. This factor influenced the estimate of the final dose. The atmospheric stability class F (moderately stable) stood out in tests conducted, as it influenced the formation of narrower plumes, and, resulted in higher dose concentrations. Consequently, there is a greater risk of manifestation of the symptoms of acute irradiation syndrome depending on the absorbed dose.

Abstract
The data center’s server power density and heat generation have increased exponentially because of the recent, unparalleled rise in the processing and storing of massive amounts of data on a regular basis. One-third of the overall energy used in conventional air-cooled data centers is directed toward cooling information technology equipment (ITE). The traditional air-cooled data centers must have low air supply temperatures and high air flow rates to support high-performance servers, rendering air cooling inefficient and compelling data center operators to use alternative cooling technology. Due to the direct interaction of dielectric fluids with all the components in the server, single-phase liquid immersion cooling (Sp-LIC) addresses mentioned problems by offering a significantly greater thermal mass and a high percentage of heat dissipation. Sp-LIC is a viable option for hyper-scale, edge, and modular data center applications because, unlike direct-to-chip liquid cooling, it does not call for a complex liquid distribution system configuration and the dielectric liquid can make direct contact with all server components. Immersion cooling is superior to conventional air-cooling technology in terms of thermal energy management however, there have been very few studies on the reliability of such cooling technology. A detailed assessment of the material compatibility of different electronic packaging materials for immersion cooling was required to comprehend their failure modes and reliability. For the mechanical design of electronics, the modulus, and thermal expansion are essential material characteristics. The substrate is a crucial element of an electronic package that has a significant impact on the reliability and failure mechanisms of electronics at both the package and the board level. As per Open Compute Project (OCP) design guidelines for immersion-cooled IT equipment, the traditional material compatibility tests from standards like ASTM 3455 can be used with certain appropriate adjustments. The primary focus of this research is to address two challenges: The first part is to understand the impact of thermal aging on the thermo-mechanical properties of the halogen-free substrate core in the single-phase immersion cooling. Another goal of the study is to comprehend how thermal aging affects the thermo-mechanical characteristics of the substrate core in the air. In this research the substrate core is aged in synthetic hydrocarbon fluid (EC100), Polyalphaolefin 6 (PAO 6), and ambient air for 720 hours each at two different temperatures: 85°C and 125°C and the complex modulus before and after aging are calculated and compared.

Published: November 2023

Abstract
Environmental, social, and governmental factors have received increased attention in the design and manufacture of electronics. Additive printed electronics processes reduce the waste streams from electronics manufacturing by eliminating plate and etch processes, which involve the selective removal of masks and conductive copper to fabricate circuits. In addition, the transition to additive print processes also allows for the elimination of hard tooling, with design changes limited to those that can be implemented quickly, reducing the time involved with design iterations. The earlier versions of additive inks involved using volatile solvents as carrier mediums for nanoparticle inks. Sustainable inks use water as the carrier medium in place of volatile solvents. Owing to the recent introduction of these formulations, less is known about the ability to form functional circuits with sustainable inks or their performance relative to the incumbent non-sustainable volatile organic solvent-based inks. In this paper, the performance of sustainable water-based solvent inks has been studied and compared with that of volatile solvent inks. The Aerosol Jet printer was used in this work to print and develop process parameters for investigation, including ultrasonic atomizer mass flow rate, sheath flow control, and stage speed, with a water-based sustainable silver nanoparticle ink. Electrical and mechanical properties were tested at various sintering temperatures and times, including resistance and shear load to failure. The results show that the electrical properties are improved by varying these parameters, and optical methods have also been used to characterize the results of the printed trace and fitted regression models that have been developed for process optimization.

Abstract
In the automotive, oil & gas, aerospace, and medical technology sectors, electronic parts are frequently subjected to higher strain loads as a result of shocks, vibrations, and drop-impact circumstances. The electrical parts in such applications are frequently exposed to severe low and high temperatures ranging from −65°C to 200°C. Furthermore, in the critical environment, these electronic equipment can be exposed to high strain rates ranging from 1 to 100 per second. SAC solder alloys are the primary alloys used to replace tin-lead solders in electronic assembly applications. Surface mount, wave soldering, and hand soldering applications have all demonstrated the effectiveness of SAC solder alloys. Numerous doped solder alloys, such as SAC-Q, SAC-R, Innolot, M758 etc. have recently been introduced in electronic components. Mechanical characteristics and statistics for lead-free solder alloys are critical for enhancing electronic package durability at high temperatures and strain rates. Additionally, thermal aging causes microstructure changes, and can significantly affect the mechanical characteristics of solder alloys. There are not enough results are available for the mechanical properties of solder alloys with extreme low to high working temperatures. Additionally, there is currently a lack of published literature on the mechanical performance of lead-free alloys under the harsh conditions of high-temperature vibration, drop, and shock. SAC Solders are tested and examined for this study at working temperatures ranging from −65°C to 200°C and at strain rates of up to 75 per second for up to 1 year of isothermal aging with a storage temperature of 100°C. Also, the obtained experimental findings and data were fitted to the Anand viscoplasticity model, and the Anand constants were determined by calculating the stress-strain behavior reported for operating temperatures ranging from −65°C to +200°C. In addition, FE analysis for drop/shock events for 1500g, for BGA package assembly with PCB has been performed. Hysteresis stress-strain curves and plastic work density curves for the solder ball joints are examined under various thermal aging circumstances for drop/shock events. Effect of various operating temperatures and aging durations on hysteresis loops and plastic work densities have been studied.

Abstract
Throughout the past decade, the field of printed electronics has gained increased research impetus and has started to make entryways into the consumer electronics product market. The main advantage of additive printed electronics is that it allows for the creation of lightweight and flexible electronic components that can be produced at a lower cost compared to traditional manufacturing methods. There are several printing techniques, conductible inks, dielectrics, solder pastes, electrically conductive adhesives, etc. that have been investigated in the literature to find the best solutions for several use cases. However, one issue that is prevalent across printing techniques and materials is the difference between the designed and actualized geometrical and electrical characteristics of printed traces. Owing to these differences, the overall achieved circuit performance differs slightly than the idealized one, and in some cases, significant differences might also be observed. To this end, the current study aims at developing a closed-loop control process for process parameter adjustment to achieve the desired electrical and physical characteristics of printed traces. In closed loop control, the output is compared to a desired setpoint, and any differences between the two are used to adjust the input. The first step in developing a closed-loop control algorithm to establish a relation between print process parameters and realized print characteristics. An inkjet printer and a particle free silver ink are used for this study. Particle-free inks are a liquid solution containing dissolved silver ions, which are beneficial for inkjet printing as they can help prevent printhead clogging. The aforementioned ink will be used for printing lines with different process parameters to establish the process parameter relation with the line geometry. This has been achieved by different machine learning methods including nonlinear regression, k-nearest neighbor regression, and Gaussian process regression. Each of these methods have been analyzed and further optimized to improve their accuracy and provide lower line width estimation errors. Ultimately a GUI for closed-loop control algorithm, which returns corrective print parameters given the desired and realized print characteristics and current print parameters, has been developed and validated.

Abstract
The development of additive manufacturing equipment and the accessibility of metal powders have recently generated considerable interest in the additive production of smart materials, often known as 4D printing. Recent research centered on ternary alloy systems of NiTi. However, iron shape memory alloy (Fe-SMA), which has outstanding superelasticity and consistent superplastic behavior across a wider temperature range, can provide a valuable counterpart for NiTi SMA. However, the viability and impact of manufacturing processing factors on Fe-SMA alloy are not well understood. The current study examines the impact of laser powder bed fusion (LPBF) processing parameters on Fe-Mn-Al-Ni shape memory alloy characteristics such as crack formation, surface roughness, laser-track morphology, density, dimensional accuracy, hardness, and phase transformation. To effectively capture thermal behavior and gather in-situ fabrication data, in-situ monitoring of sample printing was carried out utilizing a unique sensing system made up of a long wave infrared camera throughout a temperature range of −20 °C to 1500 °C. To characterize the microstructure and phase change of the manufactured samples with respect to manufacturing processing parameters, surface roughness testing, gas pycnometer, Vickers hardness testing, and differential scanning calorimetry (DSC) were used. The research showed that volumetric energy densities (VEDs) between 62 and 93 J.mm−3 produce higher-quality materials with fewer defects, which improved the densification and properties of manufactured Fe-SMA (hardness, density, and porosity).

Published: November 2023

Abstract
This paper presents the development of an underactuated prosthetic hand that offers a cost-effective, functional, and human-like alternative for individuals with upper limb amputations. The design and virtual prototyping of the hand focus on achieving a size, weight, and appearance that closely resemble a human hand, aiming to enhance user acceptance. The prosthetic hand consists of ten degrees of freedom (DoF), with four of them being actuated. Among these, three degrees of actuation (DoA) are controlled by electric motors and a tendon transmission system, while the remaining DoA is manually actuated by the user through a spring plunger. The underactuated design incorporates compliant hinges based on springs and a mechanism that decouples the motors from the fingers, enabling more natural movements and greater adaptability to different objects. By incorporating a tendon transmission system and manual thumb actuation, users can easily accomplish basic grasping tasks without relying on complex control systems. To evaluate the gripping abilities and maximum gripping force of the hand, a virtual prototype has been created and tested in different grasping scenarios. This assessment allows for performance evaluation and refinement of the design. To improve affordability and accessibility for a wider range of users, the prosthetic hand has been designed with a focus on cost-effective components and widespread utilization of additively manufactured parts.

Abstract
Soft robots can be limited in applications when their pose in space is difficult to estimate, particularly when actuated by smart thermoelectric materials with difficult-to-model mechanics. This paper presents a comparative study of approximations and simplifications that could make pose estimation computationally practical in real-world settings. To do so, this article represents a planar soft robot arm as a discretized many-link rigid arm, mapping material stiffness and actuator states to torques at the robot’s joints. Four different sets of assumptions are proposed for these mappings, varying in how stiffness is distributed throughout the arm, as well the linearity and/or hystersis of the actuator torques. We demonstrate how to calibrate each model from experimental data in a soft arm powered by shape memory alloy (SMA) wires that contract via Joule heating. Then, we perform hardware tests to predict the robot’s pose in open-loop, using only actuator temperature, and compare model performance under each simplifying assumption. Results show that adding both nonlinearity and hystersis to the actuator model improves the pose predictions, and that open challenges remain in calibrating material parameters. This study provides a platform and an initial result toward real-time pose estimation of these robots.
