Ensuring the Global Comparability of XPS Data Through Intensity Scale Calibration: Summary of ISO 5861:2024

ABSTRACTFor quantitative analyses of data acquired from x‐ray photoelectron spectroscopy (XPS) instruments to be globally comparable across industry and academia, a consistent and traceable intensity calibration method is required. ISO 5861 was prepared by Technical Committee ISO/TC 201 Surface Chemical Analysis, Subcommittee 7, Electron Spectroscopies, and describes an intensity calibration method for x‐ray photoelectron spectrometers that use quartz‐crystal monochromated Al Ka x‐rays. The method employs low‐density polyethylene reference spectra that are corrected for any instrument geometry and are traceable to the true reference spectra for gold, silver and copper held by the National Physical Laboratory (NPL), UK. This international standard generates a spectrometer relative response function for use in quantitative XPS analysis that is consistent with NPL's intensity calibration method to within 5% relative error.

Solidarity and Development: The OECD Technical Cooperation Committee in the Cold War

Abstract Since the first “development decade,” the OECD has played a key role in coordinating aid from Western countries to the Global South. Before that first decade, however, wide gaps in development separated its own member countries. Within it, therefore, a Technical Cooperation Committee (TECO) operated to provide knowledge and expertise to “intermediate development” Mediterranean countries. TECO, through a network of experts, concentrated and disseminated data, ideas, and economic policy practices to promote the “modernization” of countries not fully integrated into the international economic system and ruled by dictatorial or otherwise undemocratic regimes. On the one hand, the program concretized intra-European solidarity to spread economic development and prosperity; on the other hand, it allowed a close look at the reality of those countries. Then, beginning in the 1970s, reflecting the change in the prevailing economic culture, TECO incubated the guiding lines for the global public administration reform. This study reconstructs the history of TECO through documentation preserved in the OECD archives in Paris.

Active Control of Properties of Fresh and Hardening Concrete

Concrete mixtures have an optimized mix design in view of attaining desired properties. However, after mixing, during further processing, it is typically not possible to further adjust the performance of the fresh and hardening concrete. A new and emerging approach is to actively control the concrete properties by means of responsive particles or polymers triggered by an externally applied signal. Active control of properties of concrete refers to the concept of on- demand changes of one or more properties of the concrete after mixing by triggering a response to one or more of the constituents using a specific trigger signal (e.g. thermal, chemical, electrical, magnetic...). The on-demand control of properties can focus on the processing stage (including e.g. pumping, casting, 3D printing), the curing and hardening stage (including e.g. control of capillary pressure, shrinkage, setting, and hardening) and even on the hardened stage during service life (e.g. active corrosion control, active crack healing...). Addressing specific obstacles in cementitious environments, ensuring responsive material stability, controlling signal applicability, cost, logistics, and on-site safety is crucial for successful implementation. A RILEM technical committee has been initiated in 2023, working on the concept of Active Control of Properties of Concrete (RILEM TC 317-ACP). The committee will focus on active control of properties of fresh and hardening concrete. This paper gives a short introduction to scope and activities of TC 317-ACP.

2024 HRS perspective on advancing workflows for CIED remote monitoring

Cardiac implantable electronic devices (CIEDs) generate substantial data, often stored in image or PDF formats. Remote monitoring, now an integral component of patient care, places considerable administrative burdens on clinicians and staff, in large part due to the challenge of integrating these data seamlessly into electronic health records (EHRs). Since 2006, the Heart Rhythm Society, in collaboration with the CIED industry, has led an initiative to establish a unified standard nomenclature. This effort has harmonized terminology, aligning diverse terms with single terms approved by the Institute of Electrical and Electronics Engineers. With this foundational work complete, attention now turns to developing technical standards for interoperability, which would enable the smooth communication of CIED data between information technology systems used in clinical practice. In this manuscript, by leveraging Health Level 7 Fast Healthcare Interoperability Resources, we present a roadmap for the technical committee to guide this endeavor. We identify critical data exchange points between remote transceivers, EHRs, and third-party platforms commonly used for CIED patient data management. Our objective is to establish bidirectional communication among these resources, ensuring the accuracy, timeliness, and accessibility of clinical data for clinicians. We also anticipate substantial benefits for both clinical research and administrative efficiency through the implementation of this interoperability framework.

Beyond MABEL: An Integrative Approach to First in Human Dose Selection of Immunomodulators by the Health and Environmental Sciences Institute (HESI) Immuno-Safety Technical Committee (ITC).

Administration of a new drug candidate in a first-in-human (FIH) clinical trial is a particularly challenging phase in drug development and is especially true for immunomodulators, which are a diverse and complex class of drugs with a broad range of mechanisms of action and associated safety risks. Risk is generally greater for immunostimulators, in which safety concerns are associated with acute toxicity, compared to immunosuppressors, where the risks are related to chronic effects. Current methodologies for FIH dose selection for immunostimulators are focused primarily on identifying the minimum anticipated biological effect level (MABEL), which has often resulted in sub-therapeutic doses, leading to long and costly escalation phases. The Health and Environmental Sciences Institute (HESI) - Immuno-Safety Technical Committee (ITC) organized a project to address this issue through two complementary approaches: (i) an industry survey on FIH dose selection strategies and (ii) detailed case studies for immunomodulators in oncology and non-oncology indications. Key messages from the industry survey responses highlighted a preference toward more dynamic PK/PD approaches as in vitro assays are seemingly not representative of true physiological conditions for immunomodulators. These principles are highlighted in case studies. To address the above themes, we have proposed a revised decision tree, which expands on the guidance by the IQ MABEL Working Group (Leach et al. 2021). This approach facilitates a more refined recommendation of FIH dose selection for immunomodulators, allowing for a nuanced consideration of their mechanisms of action (MOAs) and the associated risk-to-benefit ratio, among other factors.

On the development of criteria for determining the effectiveness of technical working groups: A case study about information processes in marine conservation and fisheries management in Belize

Use of scientific information in evidence-based decision-making is critically important in addressing coastal and ocean management concerns. In an ecosystem-based management context, ensuring that the “right” information (reliable) is available can be particularly challenging as the information often resides in different organizations with different management mandates. Many governmental and intergovernmental organizations have used a range of approaches, including technical advisory committees and working groups, to facilitate multidisciplinary input into the development of appropriate policies and management practices. This study examined the roles of multiple stakeholders participating in technical working groups that assist in decision-making for marine fisheries management in Belize, a coastal country in Central America. Through interviews with members of three working groups – the Spawning Aggregation Working Group, the Managed Access Working Group, and the National Hicatee Conservation and Monitoring Network – and decision-makers in the Belize Fisheries Department, information production processes and pathways for information uptake into policy were investigated. Major characteristics of communication at the science-policy interface associated with each working group were revealed. Important communication enablers and barriers were identified related to the operation of the working groups, such as membership commitment and resource availability, which influenced knowledge exchange within and outside the groups. Based on the results, a set of requirements for the creation and operation of effective working groups was formulated with regard to requisite inputs, the operational processes, and the types and uses of the information outputs of the groups. These requirements serve as a foundation for development of indicators of the effectiveness of working groups in environmental management contexts that support communication and decision-making at science-policy interfaces.

Recent progress and current status of pancreatobiliary interventional endoscopic ultrasound in children.

In recent years, the usefulness of endoscopic ultrasound (EUS) has been recognized in children. A dedicated pediatric EUS scope has not been developed; in our experience, however, an adult EUS scope can be used. The American Society for Gastrointestinal Endoscopy Technical Committee status assessment report on pediatric endoscopy equipment provides some guidance on the feasibility of EUS according to body size. Careful monitoring is required, keeping in mind potential adverse events such as cervical esophageal perforation and unstable breathing due to tracheal compression. Most devices designed for interventional pancreatobiliary endoscopy are also available for children. Sedation or intubated general anesthesia (GA) is mandatory when performing interventional EUS (I-EUS). I-EUS for children is generally performed using GA in the operating room, but sedation in the endoscopy room is also possible under appropriate monitoring by pediatricians. I-EUS in the operating room is sometimes difficult for endoscopists to perform because of the unsuitable fluoroscopic imaging and the lack of familiar equipment and staff. Compared to GA, sedation in the endoscopy room facilitates easier and quicker repetition of procedures when necessary. Adult pancreatobiliary endoscopists perform most I-EUS procedures in the pediatric population because most pediatric endoscopists have few opportunities to perform EUS-related procedures and thus have difficulty maintaining their skills. To popularize I-EUS techniques for children, it will be necessary to establish a training program for developing pediatric endoscopists.

Detection of residual pluripotent stem cells in cell therapy products utilizing droplet digital PCR: an international multisite evaluation study.

The presence of residual undifferentiated pluripotent stem cells (PSCs) in PSC-derived cell therapy products (CTPs) is a major safety issue for their clinical application, due to the potential risk of PSC-derived tumor formation. An international multidisciplinary multisite study to evaluate a droplet digital PCR (ddPCR) approach to detect residual undifferentiated PSCs in PSC-derived CTPs was conducted as part of the Health and Environmental Sciences Institute Cell Therapy-TRAcking, Circulation & Safety Technical Committee. To evaluate the use of ddPCR in quantifying residual iPSCs in a cell sample, different quantities of induced pluripotent stem cells (iPSCs) were spiked into a background of iPSC-derived cardiomyocytes (CMs) to mimic different concentrations of residual iPSCs. A one step reverse transcription ddPCR (RT-ddPCR) was performed to measure mRNA levels of several iPSC-specific markers and to evaluate the assay performance (precision, sensitivity, and specificity) between and within laboratories. The RT-ddPCR assay variability was initially assessed by measuring the same RNA samples across all participating facilities. Subsequently, each facility independently conducted the entire process, incorporating the spiking step, to discern the parameters influencing potential variability. Our results show that a RT-ddPCR assay targeting ESRG, LINC00678, and LIN28A genes offers a highly sensitive and robust detection of impurities of iPSC-derived CMs and that the main contribution to variability between laboratories is the iPSC-spiking procedure, and not the RT-ddPCR. The RT-ddPCR assay would be generally applicable for tumorigenicity evaluation of PSC-derived CTPs with appropriate marker genes suitable for each CTP.

Intercomparison to validate implementations of different laboratories of algorithms for the analysis of surface texture

The surface texture is an important feature of machine parts for any kind of contact. The quantification of its properties has been a well-established area in quality assurance for many decades. With the increasing demand for precision and interchangeability in the globalised marketplace, the results of surface analysis must be unambiguous and reliable. This is why the International Standardization’s Technical Committee on Geometric Product Specification has updated its standards. Consequently, instrument manufacturers and calibration laboratories need to ensure that their analysis software complies with the new ISO standards. An intercomparison has therefore been carried out to validate surface texture analysis software. Over the past two decades, a number of tests have been conducted on surface texture measurement and analysis methods, including issues of instrument response, discretisation and quantisation. This article examines the numerical and computational aspects of analysis algorithms that process data sets of discrete values of finite floating-point precision as input. The method of testing texture analysis algorithms utilising software measurement standards (softgauges) and the specification of the test tasks are explained. The results of the comparison are presented and discussed.

A Study on the Color Prediction of Ancient Chinese Architecture Paintings Based on a Digital Color Camera and the Color Design System

Color paintings such as painted facades and interiors are important decoration elements of ancient Chinese architectures. The color of the paintings usually fades over time due to exposure to strong light, high humidity, high temperatures, and other environmental factors. In order to restore or reproduce the color appearance of ancient architecture paintings correctly, it was necessary to study the color degradation process of such paintings. To meet the needs of on-site colorimetric measurement of the paintings on ancient Chinese architectures, we propose using a digital color camera and the CDS (Color Design System) to measure and evaluate the colors of such paintings. The CDS is a color order system recommended by the Chinese national technical committee for color standardization (SAC/TC 120) in 2017 (GB/Z 35473-2017). The current version of the CDS atlas contains about 2740 samples which were uniformly distributed on the whole color space, and can be used to set up the colorimetric characterization model for the digital camera. Particularly, the digital CDS lookup table contains over 400 thousand samples, and it can be used to express the color of paintings on ancient Chinese architectures. In the experiment, a digital color camera was used to capture the colors of the paintings on the ancient Chinese architectures of different years based on the CDS and polynomial transform method. Moreover, a linear interpolation method was proposed for calculating and predicting the color degradation of such paintings. The experimental results show that with the increase in years, the color hue of the paintings changes slowly, while the lightness and the chroma of them fade obviously. In the future, more ancient architectures of different years and from different places should be selected as experimental samples to improve the method and the results of the paper.
