Sensitive polysulfone based chain scissioning resists for 193 nm lithography

Chain scissioning resists do not require addition of photoacid generators to function. Previously reported chain scissioning polysulfone resists were able to achieve enhanced sensitivity by incorporation of absorbing repeat units, but these groups also inhibited the depolymerization reaction, which could further enhance sensitivity. Here we report the development of sensitive polysulfone chain scissioning resists for 193 nm that are able to undergo depolymerization. The effect of depolymerization of LER is also discussed. These polymers underwent CD shrinkage upon overdose, which may be useful for double patterning processes

Development and Evaluation of a 193nm Immersion Generation-Three Fluid Candidates

The need to extend 193nm immersion lithography necessitates the development of a third generation (Gen-3) of high refractive index (RI) fluids that will enable approximately 1.7 numerical aperture (NA) imaging. A multi-pronged approach was taken to develop these materials. One approach investigated the highest-index organic thus far discovered. The second approach used a very high refractive index nanoparticle to make a nanocomposite fluid. This report will describe the chemistry of the best Gen-3 fluid candidates and the systematic approach to their identification and synthesis. Images obtained with the Gen-3 fluid candidates will also be presented for a NA ≥ 1.7

The role of line managers and co-workers in mediating informal flexibility for working family carers

Irish Academy of Management Conference on Sustainable Leadership and Management: Making a Global Impact for the Public Good. University of Galway, 23-25 August 2023Purpose: Our paper identifies the enabling mechanisms through which carer-friendly informal flexibility is enacted in the workplace and explores whether these enabling mechanisms help working carers remain in the workforce and avoid taking leave from employment. Methodology: Twenty-six working carers in Ireland were interviewed. Interviews were semi-structured, and questions were formulated around three broad themes: participants’ caregiving role; their employment situation; and the services and supports available to them. Findings: The findings highlight three mechanisms through which carer-friendly informal flexibility is enacted: reassurance and pre-emptive support; carer advocacy; and idiosyncratic deal making (i-deals). In the absence of informal flexibility, disruption to working arrangements is likely in the form of intermittent periods of leave from the workplace. Research limitations/implications: Greater diversity in the profile of our study participants could be helpful, particularly the inclusion of more male carers and those working in the private sector. Practical implications: A greater emphasis on informal, locally negotiated, flexible working arrangements would facilitate carers to remain in employment. Originality/value: Our research explores the enabling mechanisms through which carer-friendly informal flexibility is enacted. Our study uncovered the pivotal mediating role played by line managers and co-workers in supporting carers to secure access to these informal flexible working arrangements

A Scoping Review to Map the Evidence on Family Carers Who Combine Work with Care

Introduction: Family carers provide a wide range and significant amount of assistance to relatives, friends and neighbours who are ill or disabled. Statistical data from the Organisation for Economic Co-operation and Development (OECD) indicates that at least 1 in 10 adults is involved in informal, and most often unpaid care. About half of the proportion of those who participate in a caring role combine this with paid employment and balancing both roles can be a challenge. Consequently, there is increased demand for the introduction of measures to reconcile paid work and care-provision. Unfortunately, much remains unknown about the lives of family carers who balance work with care. Aim: The present work endeavours to illuminate this topic by scoping the extent, range and nature of available evidence on ‘family carers who are in paid employment’. Methods: Steps followed when carrying out the scoping review included: i) Clarifying the research purpose and question; ii) Identifying relevant research studies from various electronic databases, reference lists of identified studies, and grey or unpublished literature; iii) Selection of studies by two independent reviewers; iv) Collating data using an excel data sheet; and v) Analysing and summarising data using qualitative thematic analysis. Results: Two-hundred-and-sixty-three publications were incorporated, and these comprised a variety of research study designs, which were based in different countries. Six themes were emergent from the scoping review findings. The first was the compound carer’s experience who is a working family carer; subthemes relevant to this group were coping, health outcomes and employment outcomes. A subsequent theme was health outcomes for working family carers; health outcomes were subdivided into mental health, physical health, and health behaviour outcomes. The theme on the profile of characteristics for working family carers comprised of subthemes indicative that caring was largely a gendered activity, with age as another important variant — caring increasing at older ages. The economic impact of caring on working family carers was an eminent theme with a clear personal economic impact and national economic impact. A significant finding was the theme on conflicting priorities among working family carers; subthemes related to this were either work-to-family conflict or family-to-work conflict. The most important theme in the present work was that on employment outcomes among working family carers with subthemes characterised by employment participation, employment-related disadvantages, work-place provisions in place for this group and positive employment impacts. Finally, it was clear that there were support services for working family carers and thus this was an apparent theme; subthemes related to this were the formal services and social support services. Conclusions: Evidence on working family cares is vast and covers a wide range of topics such as compound caring, health, demographic profile, conflicting priorities, finances, employment, and support services. Working family carers face the difficult task of balancing work with care which could lead to negative outcomes related to employment, finances, and health. Implications for applicability: The pressures associated with the dual responsibility can be alleviated via the introduction of support services and policies to support working carers.Health Research Boar

NASA's Robotic Lunar Lander Development Program

NASA Marshall Space Flight Center and the Johns Hopkins University Applied Physics Laboratory have developed several mission concepts to place scientific and exploration payloads ranging from 10 kg to more than 200 kg on the surface of the moon. The mission concepts all use a small versatile lander that is capable of precision landing. The results to date of the lunar lander development risk reduction activities including high pressure propulsion system testing, structure and mechanism development and testing, and long cycle time battery testing will be addressed. The most visible elements of the risk reduction program are two fully autonomous lander flight test vehicles. The first utilized a high pressure cold gas system (Cold Gas Test Article) with limited flight durations while the subsequent test vehicle, known as the Warm Gas Test Article, utilizes hydrogen peroxide propellant resulting in significantly longer flight times and the ability to more fully exercise flight sensors and algorithms. The development of the Warm Gas Test Article is a system demonstration and was designed with similarity to an actual lunar lander including energy absorbing landing legs, pulsing thrusters, and flight-like software implementation. A set of outdoor flight tests to demonstrate the initial objectives of the WGTA program was completed in Nov. 2011, and will be discussed

Measurement of Exclusive rho+rho- Production in Mid-Virtuality Two-Photon Interactions and Study of the gamma gamma* -> rho rho Process at LEP

Exclusive rho+rho- production in two-photon collisions between a quasi-real photon, gamma, and a mid-virtuality photon, gamma*, is studied with data collected at LEP at centre-of-mass energies root(s)=183-209GeV with a total integrated luminosity of 684.8pb^-1. The cross section of the gamma gamma* -> rho+ rho- process is determined as a function of the photon virtuality, Q^2, and the two-photon centre-of-mass energy, W_gg, in the kinematic region: 0.2GeV^2 < Q^2 <0.85GeV^2 and 1.1GeV < W_gg < 3GeV. These results, together with previous L3 measurements of rho0 rho0 and rho+ rho- production, allow a study of the gamma gamma* -> rho rho process over the Q^2-region 0.2GeV^2 < Q^2 < 30 GeV^2

Bose-Einstein Correlations of Three Charged Pions in Hadronic Z^0 Decays

Bose-Einstein Correlations (BEC) of three identical charged pions were studied in 4 x 10^6 hadronic Z^0 decays recorded with the OPAL detector at LEP. The genuine three-pion correlations, corrected for the Coulomb effect, were separated from the known two-pion correlations by a new subtraction procedure. A significant genuine three-pion BEC enhancement near threshold was observed having an emitter source radius of r_3 = 0.580 +/- 0.004 (stat.) +/- 0.029 (syst.) fm and a strength of \lambda_3 = 0.504 +/- 0.010 (stat.) +/- 0.041 (syst.). The Coulomb correction was found to increase the \lambda_3 value by \~9% and to reduce r_3 by ~6%. The measured \lambda_3 corresponds to a value of 0.707 +/- 0.014 (stat.) +/- 0.078 (syst.) when one takes into account the three-pion sample purity. A relation between the two-pion and the three-pion source parameters is discussed.Comment: 19 pages, LaTeX, 5 eps figures included, accepted by Eur. Phys. J.

Measurement of the Atmospheric Muon Spectrum from 20 to 3000 GeV

The absolute muon flux between 20 GeV and 3000 GeV is measured with the L3 magnetic muon spectrometer for zenith angles ranging from 0 degree to 58 degree. Due to the large exposure of about 150 m2 sr d, and the excellent momentum resolution of the L3 muon chambers, a precision of 2.3 % at 150 GeV in the vertical direction is achieved. The ratio of positive to negative muons is studied between 20 GeV and 500 GeV, and the average vertical muon charge ratio is found to be 1.285 +- 0.003 (stat.) +- 0.019 (syst.).Comment: Total 32 pages, 9Figure
