Abstract

Objective
To provide an updated characterization of breast imaging fellowship programs in the United States to identify opportunities for improvement and standardization.

Methods
An anonymous survey was e-mailed to program directors of breast imaging fellowship programs listed on the Society of Breast Imaging website. The survey was open from April 23, 2021, through May 27, 2021. The survey was deemed exempt by the IRB.

Results
Forty-seven of 80 (59%) program directors responded, of which 36/47 (77%) represented programs dedicated 100% to breast imaging, and 11/47 (23%) represented programs dedicated 50%–75% to breast imaging. Common elements to most programs include tumor boards (47/47, 100%), journal clubs (39/47, 83%), case-based teaching sessions (35/47, 74%), didactic lectures (40/47, 85%), and participation in radiology-pathology conferences (29/47, 62%). Mammography Quality and Standards Act audit training (22/47, 47%), mammography quality control training (22/47, 47%), and formal communication training (19/47, 40%) were less common. Most programs provide exposure to wire (42/47, 89%) and wire-free localization procedures (45/47, 96%), but exposure to contrast-enhanced mammography (13/47, 28%) and molecular breast imaging (4/47, 9%) was limited. A small majority of programs (25/47, 53%) do not require weekday call; however, more (31/47, 66%) have weekend call responsibilities. Many programs (29/47, 62%) offer at least 3 weeks of elective time, which may be clinical or nonclinical.

Conclusion
Breast imaging fellowship programs vary in curricula, modality exposure, and academic policies. The results of this survey can help guide further efforts to standardize and optimize fellowship training.
Reading between the lines

Abstract
The end of entailed estates, or ‘mayorazgos’, in Spain brought about an unprecedented movement of art objects, although paradoxically the dispersal of art collections also gave rise to a renewed valuation of their restoration as a way to symbolize the restoration of the ‘mayorazgo’. The legislation that ended the status of the ‘mayorazgo’ also gave rise to the proliferation of documentation on collections, often resulting in their reordering in a way that reflected the new paradigms of the institutionalization of the arts. This paper will shed light on the strategies adopted by the dukes of Alba at this complex crossroads, as they navigated the uncharted waters of managing an art collection during and immediately following its disentailment, balancing financial interests and cultural distinction in the transition from the Old to the New Regimes.
The current management of clear cell sarcoma

Published: July 2023

Abstract
Clear cell sarcoma (CCS) is a rare melanocytic soft tissue sarcoma with a high propensity for lymphatic metastasis and poor prognosis. It is characterized by the translocation of t (12;22), resulting in the rearrangement of the EWSR1 gene and overexpression of MET. Despite improvements in the diagnosis and treatment of soft tissue sarcomas, the management of CCSs remains challenging owing to their rarity, unique biological behaviour and limited understanding of their molecular pathogenesis. The standard treatment for localized CCSs is surgical excision with negative margins. However, there is an ongoing debate regarding the role of adjuvant chemotherapy, radiotherapy and lymphadenectomy in the management of this disease. CCSs are usually resistant to conventional chemotherapy. Targeted therapies, such as sunitinib and MET inhibitors, may provide promising results. Immunotherapy, particularly immune checkpoint inhibitors, is currently under investigation as a potential treatment option for CCSs. Further research is needed to better understand the biology of CCSs and develop effective therapeutic strategies. The purpose of this review is to provide a comprehensive overview of current knowledge and advances in the diagnosis and treatment of CCSs.
Elevational range extension of the Puna Mouse, Punomys (Cricetidae), with the first record of the genus from Chile
Authors: Quiroga-Carmona Marcial , Storz Jay F , D’Elía Guillermo 
Published: July 2023

Abstract
We report an elevational record for the Andean sigmodontine Puna Mouse Punomys, which is also the first record of the genus in Chile. The record is based on a mummified specimen that we discovered at an elevation of 5,461 m (17,917 feet) in the caldera of Volcán Acamarachi, Región de Antofagasta, Chile. Results of a morphological assessment suggest that the specimen can be provisionally referred to the species P. lemminus. This new record also extends the known geographic distribution of the genus by 700 km to the south and brings the known Chilean mammal richness to a total of 170 living species and 88 genera. This finding highlights the need for increased survey efforts in more remote, high-elevation regions and demonstrates that there is still much to be learned about the mammal fauna of the Andean Altiplano.
A Qualitative Assessment to Inform Strategic Improvement of Research and Development within the USDA Forest Service
Authors: Greiner S Michelle , Schultz Courtney , Anderson Nathaniel 
Published: July 2023

Abstract
Past reviews of the USDA Forest Service (Forest Service) Research and Development (R&D) branch have identified several persistent challenges, including unclear strategic direction and a need for greater communication with end users. We conducted research focused on the Rocky Mountain Research Station (RMRS) of R&D to understand current perceptions about the station’s efficacy and strategic direction as well as its engagement with partners both inside and outside of Forest Service. We conducted fifty-eight interviews with Forest Service and RMRS leaders, scientists, and partners. Interviewees said national research priorities are unclear, and there is tension between conducting basic and applied science. Nonscientist partners said they depend on RMRS for scientific expertise. Interviewees recommended clarifying research priorities, improving leadership and communication both inside and outside of the agency, investing more in science communication, and strengthening incentives to conduct applied research. These station-level results provide insight into improvements that could be made to enhance R&D’s ability to pursue its mission.
Bayesian inference with thel1-ball prior: solving combinatorial problems with exact zeros
Authors: Xu Maoran , Duan Leo L 
Published: July 2023

AbstractThe l1-regularisation is very popular in high-dimensional statistics—it changes a combinatorial problem of choosing which subset of the parameter is zero, into a simple continuous optimisation. Using a continuous prior concentrated near zero, the Bayesian counterparts are successful in quantifying the uncertainty in the variable selection problems; nevertheless, the lack of exact zeros makes it difficult for broader problems such as change-point detection and rank selection. Inspired by the duality of the l1-regularisation as a constraint onto an l1-ball, we propose a new prior by projecting a continuous distribution onto the l1-ball. This creates a positive probability on the ball boundary, which contains both continuous elements and exact zeros. Unlike the spike-and-slab prior, this l1-ball projection is continuous and differentiable almost surely, making the posterior estimation amenable to the Hamiltonian Monte Carlo algorithm. We examine the properties, such as the volume change due to the projection, the connection to the combinatorial prior, the minimax concentration rate in the linear problem. We demonstrate the usefulness of exact zeros that simplify the combinatorial problems, such as the change-point detection in time series, the dimension selection of mixture models, and the low-rank plus-sparse change detection in medical images.

Published: July 2023

Abstract
Calcified amorphous tumors are extremely rare benign cardiac lesions that can emerge in any chamber, and have many clinical obscurities. We herein report a case of a mid-aged previously healthy male with a complaint of recurrent chest pain. Echocardiogram revealed the presence of right atrial mass that was confirmed by transesophageal echocardiography. The patient underwent total resection of the mass with attached atrial wall. Pathological studies confirmed the diagnosis of calcified amorphous tumor. Five-year follow-up was uneventful with total symptomatic relief. In conclusion, we recommend considering the diagnosis of calcified amorphous tumors in any patient with intracardiac mass.

Masquelet technique demonstrated superiority in reconstructing long bone defect after trauma or infection. However, reports in foot tumor were rare. A 24-year-old male diagnosed with calcaneal chondroblastoma who had a defect of calcaneal after intralesional curettage. We reconstructed the defect by Masquelet technique. This is the first case as far as we know that reported Masquelet technique for calcaneal tumor. The technique to treat irregular bone defects after operation can be considered in other similar situations.
Inhibition of RNA degradation integrates the metabolic signals induced by osmotic stress into the Arabidopsis circadian system

Published: July 2023

AbstractThe circadian clock system acts as an endogenous timing reference that coordinates many metabolic and physiological processes in plants. Previous studies have shown that the application of osmotic stress delays circadian rhythms via 3ʹ-phospho-adenosine 5ʹ-phosphate (PAP), a retrograde signalling metabolite that is produced in response to redox stress within organelles. PAP accumulation leads to the inhibition of exoribonucleases (XRNs), which are responsible for RNA degradation. Interestingly, we are now able to demonstrate that post-transcriptional processing is crucial for the circadian response to osmotic stress. Our data show that osmotic stress increases the stability of specific circadian RNAs, suggesting that RNA metabolism plays a vital role in circadian clock coordination during drought. Inactivation of XRN4 is sufficient to extend circadian rhythms as part of this response, with PRR7 and LWD1 identified as transcripts that are post-transcriptionally regulated to delay circadian progression.
X-ray emission from the interstellar and circumgalactic medium of elliptical galaxies based on macer simulations
Authors: Vijayan Aditi , Zhu Bocheng , Li Miao , Yuan Feng , Ho Luis C 
Published: July 2023

ABSTRACT
Interstellar medium (ISM) and circumgalactic medium (CGM) around galaxies are linked to several physical processes that drive galaxy evolution. For example, the X-ray emission from the CGM gas around ellipticals has been linked to the active galactic nucleus (AGN) feedback occurring in the host. Upcoming telescopes, such as Hot Universe Baryon Survey (HUBS) with ∼2 eV resolution, can provide us with deep insights about the hot gas properties of such galaxies that constrain these processes. In this project, we discuss X-ray emission of the ISM and CGM of elliptical galaxies simulated using macer code. We generate X-ray emission data from the macer simulations with various feedback models and produce mock observations for an instrument with high spectral resolution, which is a necessary step of selecting sources for the future observations with planned mission such as HUBS. More importantly, we establish connections between the physics of AGN and stellar feedback with the emission spectra from the ISM and CGM to investigate the possibility of using observations to constrain feedback models. We fit the X-ray spectra from these simulations with standard fitting procedures and compare the retrieved physical properties with their counterparts from the simulations to understand whether the future high-resolution observations can reliably reveal the properties of the gas in the galaxies.
1D non-LTE corrections for chemical abundance analyses of very metal-poor stars
Authors: Mashonkina L , Pakhomov Yu , Sitnova T , Smogorzhevskii A , Jablonka P , Hill V 
Published: July 2023

ABSTRACT
Detailed chemical abundances of very metal-poor (VMP; [Fe/H] &lt; −2) stars are important for better understanding the first stars, early star formation, and chemical enrichment of galaxies. Big on-going and coming high-resolution spectroscopic surveys provide a wealth of material that needs to be carefully analysed. For VMP stars, their elemental abundances should be derived based on the non-local thermodynamic equilibrium (non-LTE = NLTE) line formation because low metal abundances and low electron number density in the atmosphere produce the physical conditions favourable for the departures from LTE. The galactic archaeology research requires homogeneous determinations of chemical abundances. For this purpose, we present grids of the 1D-NLTE abundance corrections for lines of Na i, Mg i, Ca i, Ca ii, Ti ii, Fe i, Zn i, Zn ii, Sr ii, and Ba ii in the range of atmospheric parameters that represent VMP stars on various evolutionary stages and cover effective temperatures from 4000 to 6500 K, surface gravities from $\rm log g$ = 0.5 to 5.0, and metallicities −5.0 ≤ [Fe/H] ≤ −2.0. The data is publicly available, and we provide the tools for interpolating in the grids online.
Using grey sirens to resolve the Hubble–Lemaître tension
Authors: Gupta Ish 
Published: July 2023

ABSTRACT
The measurement of the Hubble–Lemaître constant (H0) from the cosmic microwave background and the Type IA supernovae are at odds with each other. One way to resolve this tension is to use an independent way to measure H0. This can be accomplished by using gravitational-wave (GW) observations. Previous works have shown that with the onset of the next generation of GW detector networks, it will be possible to constrain H0 to better than 2 per cent precision (which is enough to resolve the tension) with binary black hole systems that are extremely well localized in the sky, also called golden dark sirens. Bright sirens like binary neutron star systems can also help resolve the tension if both the GW and the following electromagnetic counterpart are detected. In this work, we show that neutron star-black hole (NSBH) mergers can act both as golden dark sirens as well as bright sirens, thus, assigning them the term grey sirens. We assess the potential of using NSBH mergers to measure H0 and find that the Voyager network might be able to resolve the tension in an observation span of 5 yr. The next generation networks, which include the Cosmic Explorer detectors and the Einstein Telescope will be able to measure H0 to sub-per cent level just by using NSBH mergers.
Metallicity beats sSFR: the connection between superluminous supernova host galaxy environments and the importance of metallicity for their production
Authors: Cleland Cressida , McGee Sean L , Nicholl Matt 
Published: July 2023

ABSTRACT
We analyse 33 Type I superluminous supernovae (SLSNe) taken from Zwicky Transient Facility (ZTF)’s Bright Transient Survey to investigate the local environments of their host galaxies. We use a spectroscopic sample of galaxies from the Sloan Digital Sky Survey (SDSS) to determine the large-scale environmental density of the host galaxy. Noting that SLSNe are generally found in galaxies with low stellar masses, high star formation rates (SFRs), and low metallicities, we find that SLSN hosts are also rarely found within high-density environments. Only $3\substack{+9 \\ -1}$ per cent of SLSN hosts were found in regions with two or more bright galaxies within 2 Mpc. For comparison, we generate a sample of 662 SDSS galaxies matched to the photometric properties of the SLSN hosts. This sample is also rarely found within high-density environments, suggesting that galaxies with properties required for SLSN production favour more isolated environments. Furthermore, we select galaxies within the IllustrisTNG simulation to match SLSN host galaxy properties in colour and stellar mass. We find that the fraction of simulated galaxies in high-density environments quantitatively match the observed SLSN hosts only if we restrict to simulated galaxies with metallicity 12 + log (O/H) ≤ 8.12. In contrast, limiting to only the highest specific star formation rate (sSFR) galaxies in the sample leads to an overabundance of SLSN hosts in high-density environments. Thus, our measurement of the environmental density of SLSN host galaxies appears to break the degeneracy between low metallicity and high sSFR as the driver for SLSN hosts and provides evidence that the most constraining factor on SLSN production is low metallicity.

ABSTRACT
We present an application of unsupervised Machine Learning clustering to the PAU survey of galaxy spectral energy distribution (SED) within the COSMOS field. The clustering algorithm is implemented and optimized to get the relevant groups in the data SEDs. We find 12 groups from a total number of 5234 targets in the survey at 0.01 &lt; z &lt; 0.28. Among the groups, 3545 galaxies (68 per cent) show emission lines in the SEDs. These groups also include 1689 old galaxies with no active star formation. We have fitted the SED to every single galaxy in each group with CIGALE. The mass, age, and specific star formation rates (sSFR) of the galaxies range from 0.15 &lt; age/Gyr &lt;11; 6 &lt; log (M⋆/M⊙) &lt;11.26, and −14.67 &lt; log (sSFR/yr−1) &lt;−8. The groups are well-defined in their properties with galaxies having clear emission lines also having lower mass, are younger and have higher sSFR than those with elliptical like patterns. The characteristic values of galaxies showing clear emission lines are in agreement with the literature for starburst galaxies in COSMOS and GOODS-N fields at low redshift. The star-forming main sequence, sSFR versus stellar mass and UVJ diagram show clearly that different groups fall into different regions with some overlap among groups. Our main result is that the joint of low- resolution (R ∼ 50) photometric spectra provided by the PAU survey together with the unsupervised classification provides an excellent way to classify galaxies. Moreover, it helps to find and extend the analysis of extreme ELGs to lower masses and lower SFRs in the local Universe.
The Royal Road Progression in Japanese Popular Music
Authors: Ramage Maxwell 
Published: July 2023

AbstractThe so-called royal road progression (RRP), whose archetypal lead-sheet representation is F–G–Em–Am, is a distinctive feature of modern Japanese popular music. The RRP arose from the manipulation of basic elements of diatonic harmony and coexists with several closely related progressions in J-pop style. Composers often use the RRP to lend Aeolian flavor to major-key songs; however, the RRP is a tonally flexible pattern. After presenting a typology of phrases that use the RRP, I argue that the progression can articulate partial tonic function and can induce a binary tonal system, which occupies the conceptual space between tonal pairing and double-tonic complex. I also provide a diachronic account of the RRP as an element of J-pop history and pop-music history in general. By relating the concepts of partial tonic function and binary tonal system to the RRP, this paper gives insight into the understudied harmonic language of J-pop and invites application of the concepts to other musics.

Published: July 2023

Abstract
To survey the whole-body positron emission tomography/computed tomography (PET-CT) examinations in Jiangsu Province and establish the diagnostic reference levels (DRL). A total of nine hospitals in southern, central and northern Jiangsu Provinces were selected. Activity duration product (ADP), activity per body weight (AW), dose-length product (DLP) and total effective dose (ET) were choosen to establish DRLs for whole-body PET-CT examinations. DRL and achievable dose (AD) were calculated according to International Commission on Radiological Protection report. The conversion coefficient method was used to calculate the ET induced by PET-CT whole-body imaging. DRLs of whole-body PET-CT examinations in Jiangsu Province were set to be 922 mGy·cm (DLP), 4453 MBq.min (ADP), 5.22 MBq.kg−1(AW), 19.8 mSv (ET). The ET for whole-body PET-CT examinations is higher than other countries. The effective dose from radionuclides (EF) in female patients is lower than that in male patients. Effective doses from CT(ECT), ET and ECT/ET in female patients are higher than that in male patients (P &lt; 0.01). Provincial DRLs are established for four radiation metrics in whole-body PET-CT examinations. DRL of AW in whole-body PET-CT examinations is at the medium level, and DLP is higher than that reported in most literature, which has the potential to be further reduced.
