Radio-Optical Galaxy Shape and Shear Correlations in the COSMOS Field using 3 GHz VLA Observations

We present a weak lensing analysis of the 3 GHz VLA radio survey of the COSMOS field, which we correlate with overlapping HST-ACS optical observations using both intrinsic galaxy shape and cosmic shear correlation statistics. After cross-matching sources between the two catalogues, we measure the correlations of galaxy position angles and find a Pearson correlation coefficient of $0.14 \pm 0.03$. This is a marked improvement from previous studies which found very weak, or non-existent correlations, and gives insight into the emission processes of radio and optical galaxies. We also extract power spectra of averaged galaxy ellipticities (the primary observable for cosmic shear) from the two catalogues, and produce optical-optical, radio-optical and radio-radio spectra. The optical-optical auto-power spectrum was measured to a detection significance of 9.80$\sigma$ and is consistent with previous observations of the same field. For radio spectra (which we do not calibrate, given the unknown nature of their systematics), although we do not detect significant radio-optical (1.50$\sigma$) or radio-radio (1.45$\sigma$) $E$-mode power spectra, we do find the $E$-mode spectra to be more consistent with the shear signal expected from previous studies than with a null signal, and vice versa for $B$-mode and $EB$ cross-correlation spectra. Our results give promise that future radio weak lensing surveys with larger source number densities over larger areas will have the capability to measure significant weak lensing signals.Comment: 19 pages, 17 figures, accepted for publication in MNRA

A miniaturized 3 dimensional bandpass frequency selective surface

A planar bandpass frequency selective surface (FSS) is proposed along with an alternative 3D element design with the intent of miniaturizing the unit cell. The two structures are simulated in CST and compared. Such techniques show the potential of using 3D elements in FSS design to miniaturize the structure for space constrained applications

Oral Presentation objectives1) To develop awareness of our innovative workshop delivered to our Simulated Patients to increase their understanding of unconscious biases, how these might impact their work as Simulated Patients in our teaching and assessments and to equip them with skills to challenge and interrogate their automatic thinking. 2) To consider Simulated patient feedback and reflections and my own critical reflections on the Workshop.3) To share best practice with delegates regarding their own experiences of developing Unconscious Bias training to Simulated Patients / other groups in their own institutions

PC030. Unconscious Bias Training for our Simulated Patients: Showcasing a new and innovative workshop

Background:Unconscious biases are beliefs, attitudes and stereotypes that can affect our understanding and decisions in a way that we're not aware of. If steps aren't taken to avoid acting on such biases, it can lead to unfair treatments and discriminatory practices (General Medical Council).At the Hull York Medical School, we are committed to ensuring an inclusive environment and developing a culture of cultural competence which includes raising awareness of unconscious bias. We are fortunate to have a large pool of highly trained Simulated Patients (SPs) who can both simulate patient scenarios and deliver specific, descriptive and non-judgmental feedback in teaching sessions across all five years of the curriculum. Since the arrival of the covid pandemic, Simulated Patients have played a crucial role in the delivery of teaching and assessments across all five years of our MBBS programme. We are aware that, despite ongoing efforts, our Simulated Patient pool is less diverse than both our student and staff cohorts. This workshop is part of a wider school commitment to raise awareness of the impact of Unconscious Bias on our interactions with students, patients and staff. This training was informed by the adaptation of Bennett’s intercultural competency model1 by Teal et al2

Artificially engineered capacitors for discrete high-frequency electronic circuitry

The concept of the artificially engineered capacitor (AEC) is presented as a 3D printable 3D capacitive component for the use in discrete RF/microwave electronic circuitry. The intention of the AEC concept is a highly customizable 3D printable component whose capacitance value is stable over a wider frequency band when compared to commercial alternatives. AECs can be viewed as impedance structures with predominantly capacitive characteristics. Both series and shunt AEC configurations are considered with simulation and measurement data along with equivalent circuit models. The tolerance of the equivalent capacitance over frequency is focused upon in this paper. Within the 40 % tolerance band from the nominal value an improvement of 26 % and 197 % frequency band was achieved for the series and shunt variants respectively when compared to a commercial alternative. Further simulations show that with finer 3D printing resolutions, this frequency stable bandwidth can be further increased. Finally, an example design application of a halfwavelength microstrip resonator is presented in which the AECs’ Q factor is measured, and the its equivalent circuits are implemented and validated via simulations and measurements.</div

Testing the use of static chamber boxes to monitor greenhouse gas emissions from wood chip storage heaps

This study explores the use of static chamber boxes to detect whether there are fugitive emissions of greenhouse gases (GHGs) from a willow chip storage heap. The results from the boxes were compared with those from 3-m stainless steel probes inserted into the core of the heap horizontally and vertically at intervals. The results from probes showed that there were increases of carbon dioxide (CO2) concentrations in the heap over the first 10 days after heap establishment, which were correlated with a temperature rise to 60 °C. As the CO2 declined, there was a small peak in methane (CH4) concentration in probes orientated vertically in the heap. Static chambers positioned at the apex of the heap detected some CO2 fluxes as seen in the probes; however, the quantities were small and random in nature. A small (maximum 5 ppm) flux in CH4 occurred at the same time as the probe concentrations peaked. Overall, the static chamber method was not effective in monitoring fluxes from the heap as there was evidence that gases could enter and leave around the edges of the chambers during the course of the experiment. In general, the use of standard (25 cm high) static chambers for monitoring fluxes from wood chip heaps is not recommended

The Phase Structure of Mass-Deformed SU(2)xSU(2) Quiver Theory

The phase structure of the finite SU(2)xSU(2) theory with N=2 supersymmetry, broken to N=1 by mass terms for the adjoint-valued chiral multiplets, is determined exactly by compactifying the theory on a circle of finite radius. The exact low-energy superpotential is constructed by identifying it as a linear combination of the Hamiltonians of a certain symplectic reduction of the spin generalized elliptic Calogero-Moser integrable system. It is shown that the theory has four confining, two Higgs and two massless Coulomb vacua which agrees with a simple analysis of the tree-level superpotential of the four-dimensional theory. In each vacuum, we calculate all the condensates of the adjoint-valued scalars.Comment: 12 pages, JHEP.cl
