The WLCG Authorisation Working Group was formed in July 2017 with the objective to understand and meet the needs of a future-looking Authentication and Authorisation Infrastructure (AAI) for WLCG experiments. Much has changed since the early 2000s when X.509 certificates presented the most suitable choice for authorisation within the grid; progress in token based authorisation and identity federation has provided an interesting alternative with notable advantages in usability and compatibility with external (commercial) partners. The need for interoperability in this new model is paramount as infrastructures and research communities become increasingly interdependent. Over the past two years, the working group has made significant steps towards identifying a system to meet the technical needs highlighted by the community during staged requirements gathering activities. Enhancement work has been possible thanks to externally funded projects, allowing existing AAI solutions to be adapted to our needs. A cornerstone of the infrastructure is the reliance on a common token schema in line with evolving standards and best practices, allowing for maximum compatibility and easy cooperation with peer infrastructures and services. We present the work of the group and an analysis of the anticipated changes in authorisation model by moving from X.509 to token based authorisation. A concrete example of token integration in Rucio is presented., Comment: 8 pages, 3 figures, to appear in the proceedings of CHEP 2019

Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facilities and experiments, or to upgrade existing ones. Similarly, it requires commensurate investment in the R&D of software to acquire, manage, process, and analyse the shear amounts of data to be recorded. In planning for the HL-LHC in particular, it is critical that all of the collaborating stakeholders agree on the software goals and priorities, and that the efforts complement each other. In this spirit, this white paper describes the R&D activities required to prepare for this software upgrade.

Physics ,QC1-999 - Abstract
Since 2020, UKRI/STFC’s Scientific Computing Department (SCD) have developed several remote-first public engagement activities, drawing on its long and rich history of delivering face to face public engagement and outreach, as part of the wider STFC programme. With COVID19 restrictions lifted in the UK, STFC has been able to resume in-person public engagement, both on site and in public places. However, this has not meant a complete return to exclusively in-person engagement, but rather, recognising the clear benefits of remote engagement to meeting our strategic public engagement aims, STFC has produced a blended programme for 2022/23, with a mixture of in-person, remote and hybrid events. This paper presents how the remote activities have evolved since their initial creation, how the remote activities have become part of a blended programme and how the in-person activities in place since before the pandemic have been improved as a result of developing the remote activities.

Physics ,QC1-999 - Abstract
UKRI/STFC’s Scientific Computing Department (SCD) has a long and rich history of delivering face to face public engagement and outreach, both on site and in public places, as part of the wider STFC programme. Due to the global COVID-19 pandemic, SCD was forced to abandon an extensive planned programme of public engagement, alongside altering the day-to-day working methods of the majority of its staff. SCD had to respond rapidly to create a new, remote only, programme for the summer and for the foreseeable future. This was initially an exercise in improvisation, identifying existing activities that could be delivered remotely with minimal changes. As the pandemic went on, SCD also created new resources specifically for a remote audience and adapted existing activities where appropriate, using our evaluation framework to ensure these activities continued to meet the aims of the in-person programme. This paper presents the process through which this was achieved, some of the benefits and challenges of remote engagement and the plans for 2021 and beyond.

Physics ,QC1-999 - Abstract
Public Engagement (PE) with science should be more than “fun” for the staff involved. PE should be a strategic aim of any publically funded science organisation to ensure the public develops an understanding and appreciation of their work, its benefits to everyday life and to ensure the next generation is enthused to take up STEM careers. Most scientific organisations do have aims to do this, but very few have significant budgets to deliver this. In a landscape of ever tightening budgets, how can we develop a sustainable culture of PE within these organisations? UKRI/STFC’s Scientific Computing Department present how we have worked to embed a culture of PE with the department by developing our early career staff members; highlighting the impact PE makes at the departmental and project level; and linking PE to our competency framework. We will also discuss how our departmental work interacts with and complements STFC’s organisational-wide PE effort, such as making use of a shared evaluation framework that allows us to evaluate our public engagement activities against their goals and make strategic decisions about the programme’s future direction.

Physics ,QC1-999 - Abstract
IRIS is the co-ordinating body of a UK science eInfrastructure and is a collaboration between UKRI-STFC, its resource providers and representatives from the science activities themselves. We describe an ongoing project to build a security policy trust framework suitable for use across the IRIS community using the AARC Policy Development Kit. Derived from existing practice, the AARC PDK aims to assist in efficiently bootstrapping a Research Infrastructure in the operation of an authentication and authorisation infrastructure in line with the AARC Blueprint Architecture, making resources accessible to researchers in an easy and secure fashion. We document the experience gained to date by the IRIS community in adopting component policies of the AARC PDK to build a trust framework to form a foundation for resource sharing, access and trust for a national infrastructure collaboration.

Physics ,QC1-999 - Abstract
GOCDB is the official repository for storing and presenting EGI and WLCG topology and resource information. It is a definitive information source, with the emphasis on user communities to maintain their own data. It is intentionally designed to have no dependencies on other operational tools for information. In recent years, funding sources and user communities have evolved and GOCDB is developing to meet the resulting new requirements, such as allowing more programmatic updates to the data within GOCDB. We will explain the roadmap for developing GOCDB and the motivation for the changes on that Roadmap. As GOCDB, and the team supporting it, has evolved, we have re-examined the underpinning architecture for GOCDB. We will set out the changes we have made as a result.

- Abstract
Particle physics has an ambitious and broad experimental programme for the coming decades. This programme requires large investments in detector hardware, either to build new facilities and experiments, or to upgrade existing ones. Similarly, it requires commensurate investment in the R&D of software to acquire, manage, process, and analyse the shear amounts of data to be recorded. In planning for the HL-LHC in particular, it is critical that all of the collaborating stakeholders agree on the software goals and priorities, and that the efforts complement each other. In this spirit, this white paper describes the R&D activities required to prepare for this software upgrade. ©2019

Firstly, the biosynthesis and physiological role of thromboxanes and the potential for a thromboxane A2 antagonist in cardiovascular therapy are discussed. Secondly, the importance of fluorine in drug design is outlined and the syntheses of a series of thromboxane A2 structural analogues are reviewed. This is concluded by proposing how fluorine substitution should allow synthesis of a stable structural analogue of thromboxane A2 which may have antagonistic properties. Finally, the synthetic conversion of a carbohydrate precursor, levoglucosan, into a suitable precursor to 10-α-flurothromboxane A2 is discussed in detail.

- Abstract
The WLCG Authorisation Working Group formed in July 2017 with the objective to understand and meet the needs of a future-looking Authentication and Authorisation Infrastructure (AAI) for WLCG experiments. Much has changed since the early 2000s when X.509 certificates presented the most suitable choice for authorisation within the grid; progress in token based authorisation and identity federation has provided an interesting alternative with notable advantages in usability and compatibility with external (commercial) partners. The need for interoperability in this new model is paramount as infrastructures and research communities become increasingly interdependent. Over the past two years, the Working Group has made significant steps towards identifying a system to meet the technical needs highlighted by the community during staged requirements gathering activities. Enhancement work has been possible thanks to externally funded projects, allowing existing AAI solutions to be adapted to our needs. A cornerstone of the infrastructure is the reliance on a common token schema in line with evolving standards and best practices, allowing for maximum compatibility and easy cooperation with peer infrastructures and services. We will present the work of the group and an analysis of the anticipated changes in authorisation model by moving from X.509 to token based authorisation. A concrete example of token integration in Rucio, FTS and storage (dCache and StoRM) will be discussed.

Public Engagement (PE) with science should be more than "fun" for the staff involved. PE should be a strategic aim of any publically funded science organisation to ensure the public develops an understanding and appreciation of their work, its benefits to everyday life and to ensure the next generation is enthused to take up STEM careers. Most scientific organisations do have aims to do this, but very few have significant budgets to deliver this. In a landscape of ever tightening budgets, how can we develop a sustainable culture of PE within these organisations? UKRI/STFC's Scientific Computing Department present how we have worked to embed a culture of PE with the department by developing our early career staff members; highlighting the impact PE makes at the departmental and project level; and linking PE to our competency framework. We will also discuss how our departmental work interacts with and complements STFC's organisational-wide PE effort, such as making use of a shared evaluation framework that allows us to evaluate our public engagement activities against their goals and make strategic decisions about the programme's future direction.

GOCDB is the official repository for storing and presenting EGI and WLCG topology and resource information. It is a definitive information source, with the emphasis on user communities to maintain their own data. It is intentionally designed to have no dependencies on other operational tools for information. In recent years, funding sources and user communities have evolved and GOCDB is developing to meet the resulting new requirements, such as allowing more programmatic updates to the data within GOCDB. We will explain the roadmap for developing GOCDB and the motivation for the changes on that Roadmap. As GOCDB, and the team supporting it, has evolved, we have re-examined the underpinning architecture for GOCDB. We will set out the changes we have made as a result. [ABSTRACT FROM AUTHOR]

IRIS is the co-ordinating body of a UK science eInfrastructure and is a collaboration between UKRI-STFC, its resource providers and representatives from the science activities themselves. We describe an ongoing project to build a security policy trust framework suitable for use across the IRIS community using the AARC Policy Development Kit. Derived from existing practice, the AARC PDK aims to assist in efficiently bootstrapping a Research Infrastructure in the operation of an authentication and authorisation infrastructure in line with the AARC Blueprint Architecture, making resources accessible to researchers in an easy and secure fashion. We document the experience gained to date by the IRIS community in adopting component policies of the AARC PDK to build a trust framework to form a foundation for resource sharing, access and trust for a national infrastructure collaboration.

- Abstract
Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2005., Includes bibliographical references (leaves 28-29)., This work develops a method for capturing some of the kinetic energy ordinarily lost during braking on bicycles to power LED safety flashers. The system is designed to eliminate: (a) battery changing in popular LED flashers, and (b) the "generator drag" associated with battery-less human-powered bicycle lights and flashers. System sizing, mechanical design considerations, potential end-user factors, and a model for braking frequencies in urban settings are discussed. With the urban commuter cyclist in mind as a potential user of the regenerative braking system, custom direct-pull brake calipers (or "V-Brakes") were designed and manufactured to include both conventional friction pads in addition to a DC motor to be used as a generator for kinetic energy capture. The energy captured by the DC motor during braking is passed through a full wave bridge to a bank of Nickel-Cadmium batteries at an efficiency of 79%. The output of the full wave bridge and the batteries are connected in parallel with a step-down switching voltage regulator, which insulates the LED safety flasher from voltage spikes due to braking at high cycling speeds. The performance of the final prototype was evaluated at cycling speeds ranging from 8 to 19 mph and braking frequencies ranging from 2 to 8 operations/stops per mile of travel., (cont.) From the mean power flow (charging) into the batteries per unit distance of travel and the power required by LED safety flashers, the effectiveness of the system at each speed and stopping frequency is examined. For cyclists traveling at average speeds of 10 mph or higher, the LED safety flashers can be powered continuously for stopping frequencies of 8 times per mile and semi-continuously (> 50% of the time) for stopping frequencies of at least 4 times per mile. As such, the system is determined to be potentially useful to urban commuter cyclists, who frequently perform braking operations at regularly spaced intersections and traffic signals, and who regularly travel by bicycle in low-light conditions (dawn or dusk), though usually less than 50% of the time., by Ian M. Collier., S.B.
