Published: June 2022

AbstractHashing scheme is a high‐efficiency technique for processing massive images. Two critical metrics of the hashing scheme are discrimination and robustness, but most schemes do not get satisfied classification performance between them. This paper proposes a novel hashing scheme via image feature map and 2D PCA. First, the proposed scheme extracts local phase quantization (LPQ) features in the frequency domain and local ternary pattern (LTP) features in the spatial domain, and combines them to construct an image feature map. Second, the proposed scheme conducts dimension reduction via 2D PCA for learning features from the image feature map. Last, the learned features are compressed to generate the hash sequence. Performances are tested on open image datasets. The results demonstrate that the proposed scheme can make a good balance between discrimination and robustness. In addition, the classification and copy detection of the proposed scheme are both superior to those of some famous hashing schemes.
Finite‐time stability of singular multi‐agent systems with input time‐varying delay and non‐linear dynamics via non‐fragile controller

Published: June 2022

AbstractThis paper deals with the finite‐time stability problem of non‐linear singular multi‐agent systems subject to controller gain disturbance via a distributed non‐fragile controller. The existing literature on this problem only applies to normal multi‐agent systems, or ignores the possible change of control gain in the practical application of the controller, or requires that there is no time‐varying delay in the control input. How to tackle the finite‐time stability problem of singular multi‐agent systems by considering input time‐varying delay, Lipschitz non‐linear dynamics and controller gain perturbation simultaneously is an open issue. In order to solve this problem, a distributed non‐fragile controller is proposed for each agent to make the finite‐time stability problem solved for any connected undirected connection topology. With the help of a Linear matrix inequality and a Lyapunov integral appropriate expression, the difficulty caused by the irreversibility of singular system matrices is solved. Then, a sufficient condition to ensure the finite‐time stability of the closed‐loop system is obtained for the singular multi‐agent system including controller disturbance, input–output delay and non‐linear dynamics. Finally, two numerical examples are used to illustrate the effectiveness of the proposed method.

Context.Globular clusters (GCs) associated with the Sagittarius dwarf spheroidal galaxy (Sgr dSph) have evolved under the gravitational potential of both Sgr dSph and the Milky Way. The effects of these potentials are most pronounced in the extra-tidal regions as compared to the central regions of the GCs.Aims.We aim to study the extra-tidal regions of the GCs that are possibly associated with Sgr dSph, namely Arp 2, Terzan 8, NGC 5634, NGC 6284, Terzan 7, NGC 2419, NGC 4147, M 54 and Pal 12, using data from theGaiaearly data release 3.Methods.We selected the extra-tidal candidates based on their angular distances from the cluster centre in the RA-Dec plane, proper motions of the clusters and the individual extra-tidal star candidates, and their positions on the colour-magnitude diagrams of the clusters.Results.We found extra-tidal candidates for the nine studied GCs. For eight of them, the surface density of candidate extra-tidal stars in the vicinity of the clusters is in significant excess with respect to more distant surrounding fields. No extended extra-tidal features beyond 5 tidal radii were detected for any of the clusters.Conclusions.We publish a list of the most probable extra-tidal candidates that we determined usingGaiaastrometric and photometric data. Our analysis shows that the clusters that are associated with Sgr dSph are more likely affected by the gravitational potential of the Sgr, as the distribution of extra-tidal stars is elongated in the same direction as the local stream. NGC 4147 is the only exception. We found some high-probability candidate extra-tidal stars in several of the analysed clusters. We failed to detect any coherent large-scale tidal tail around them.

Context. Gliese-832 (GJ 832) is an M2V star hosting a massive planet on a decade-long orbit, GJ 832b, discovered by radial velocity (RV). Later, a super Earth or mini-Neptune orbiting within the stellar habitable zone was reported (GJ 832c). The recently determined stellar rotation period (45.7 ± 9.3 days) is close to the orbital period of putative planet c (35.68 ± 0.03 days).
Aims. We aim to confirm or dismiss the planetary nature of the RV signature attributed to GJ 832c, by adding 119 new RV data points, new photometric data, and an analysis of the spectroscopic stellar activity indicators. Additionally, we update the orbital parameters of the planetary system and search for additional signals.
Methods. We performed a frequency content analysis of the RVs to search for periodic and stable signals. Radial velocity time series were modelled with Keplerians and Gaussian process (GP) regressions alongside activity indicators to subsequently compare them within a Bayesian framework.
Results. We updated the stellar rotational period of GJ 832 from activity indicators, obtaining 37.5+1.4-1.5 days, improving the precision by a factor of 6. The new photometric data are in agreement with this value. We detected an RV signal near 18 days (FAP < 4.6%), which is half of the stellar rotation period. Two Keplerians alone fail at modelling GJ 832b and a second planet with a 35-day orbital period. Moreover, the Bayesian evidence from the GP analysis of the RV data with simultaneous activity indices prefers a model without a second Keplerian, therefore negating the existence of planet c.

Context. Great strides have been made in recent years in the understanding of the mechanisms involved in the formation and evolution of planetary systems. Despite this, many observational findings have not yet been corroborated by astrophysical explanations. A fine contribution to the study of planetary formation processes comes from the study of young, low-mass planets, with short orbital periods (<100 days). In the last three years, the NASA/TESS satellite has identified many planets of this kind and their characterization is clearly necessary in order to understand how they formed and evolved.
Aims. Within the framework of the Global Architecture of Planetary System (GAPS) project, we performed a validation and characterization (radius and mass) of the ultra-short period planet TOI-1807 b, which orbits its young host star BD+39 2643 (~300 Myr) in only 13 h. This is the youngest ultra-short period planet discovered so far.
Methods. Thanks to a joint modeling of the stellar activity and planetary signals in the TESS light curve and in new HARPS-N radial-velocity measurements, combined with accurate estimation of stellar parameters, we validated the planetary nature of TOI-1807 b and measured its orbital and physical parameters.
Results. By using astrometric, photometric, and spectroscopic observations, we found that BD+39 2643 is a young, active K dwarf star and a member of a 300 ± 80 Myr old moving group. Furthermore, it rotates in Prot = 8.8 ± 0.1 days. This star hosts an ultra-short period planet, exhibiting an orbital period of only Pb = 0.54937 ± 0.00001 days. Thanks to the exquisite photometric and spectroscopic series, along with the accurate information on its stellar activity, we measured both the radius and the mass of TOI-1807 b with high precision, obtaining PP,b = 1.37 ± 0.09 R⊕ and MP,b = 2.57 ± 0.50 M⊕. These planet parameters correspond to a rocky planet with an Earth-like density (ρb = 1.0 ± 0.3 ρ⊕) and no extended H/He envelope. From the analysis of the age-RP distribution for planets with well measured ages, we inferred that TOI-1807 b may have already lost a large part of its atmosphere over the course of its 300 Myr lifetime.

Theranostics bei gut bis mäßig differenzierten GEP-NEN
Authors: Hartrampf Philipp , Werner Rudolf , Buck Andreas 
Published: June 2022

ZusammenfassungNeuroendokrine Neoplasien (NEN) sind seltene, heterogene und typischerweise langsam wachsende Tumoren. Die häufigsten Lokalisationen finden sich im gastro-entero-pankreatischen System
(GEP-NEN). NENs werden nach proliferativer Aktivität (Ki-67-Index) eingeteilt (G1–3). Gut differenzierte Tumoren exprimieren dabei typischerweise Somatostatinrezeptoren (SSTR), die als
Zielstruktur in der nuklearmedizinischen Theranostik dienen. Bei diesem Prinzip kann nach einer diagnostischen molekularen Bildgebung, meist mittels
Positronenemissionstomografie/Computertomografie (PET/CT), eine individuell zugeschnittene Peptidradiorezeptortherapie (PRRT) mit einem β-Strahler-markierten Radiopharmakon erfolgen. In
Metaanalysen zeigte die Diagnostik mittels SSTR-gerichteter PET/CT eine Sensitivität von 93% und eine Spezifität von 96%. Die SSTR-gerichtete Diagnostik kann auch zur radioaktiven Markierung
von Tumoren verwendet werden, um eine zielgerichtete Chirurgie zu ermöglichen. Die Indikation zur Einleitung einer PRRT soll stets in einer interdisziplinären Tumorkonferenz getroffen
werden. Ein Tumorprogress unter der vorangegangenen Therapie sollte dokumentiert sein. Die Therapie wird intravenös und insgesamt 4-mal in 8-wöchigem Abstand in spezialisierten
nuklearmedizinischen Zentren verabreicht. Die Wirksamkeit der PRRT wurde in der NETTER-1-Studie prospektiv untersucht und konnte eine signifikante Verbesserung des progressionsfreien
Überlebens (primärer Endpunkt) zeigen. Ausgehend von diesen Studienergebnissen steht mit Lutathera (177Lu-DOTATATE) inzwischen ein in Deutschland zugelassenes Radiopharmazeutikum zu
Behandlung von nicht resektablen oder metastasierten bzw. progredienten, gut differenzierten (G1 und G2), SSTR-positiven GEP-NEN zur Verfügung.

AbstractUltrasound has become an essential diagnostic tool in gynecology, and every practicing gynecologist must be able to differentiate normal from pathologic findings, such as benign or malignant pelvic masses, adnexal torsion, pelvic inflammation disease, endometriosis, ectopic pregnancies, and congenital uterine malformations at least on a basic level. A standardized approach to the correct settings of the ultrasound system, the indications for gynecologic ultrasound investigations, and the sonographic appearance of normal anatomy and common pathologic findings in the standard planes are important prerequisites for safe and confident clinical management of gynecologic patients. Based on current publications and different national and international guidelines, updated DEGUM, ÖGUM, and SGUM recommendations for the performance of basic gynecologic ultrasound examinations were established.
Understanding State-Level Advocacy: A Guide for Hearing Healthcare Professionals
Authors: Roman Aaron M. 
Published: June 2022

AbstractAdvocacy is a core component of moving the hearing healthcare environment forward to optimize patient care and allow providers to work to the full extent of their scope of practice. Despite its importance, advocacy, particularly at the level of state governments, can present to many as a daunting, sometimes futile, task. The purpose of this article is to describe advocating at the state level for hearing healthcare service providers. This article will discuss considerations for audiology practitioners interested in state-level advocacy, including variations in state government organization, benefits and barriers to state advocacy, and state-level issues that affect practitioners.
Defining Audiology through Occupational and Health Policy Action
Authors: Miller Erin L. , Jilla Anna Marie , Arnold Michelle L. 
Published: June 2022

AbstractMany barriers to accessibility exist for Medicare beneficiaries seeking hearing and balance care such as availability of providers, coverage for services, and ability to pay. Other statutory and administrative barriers exist including the need for physician orders to have audiology services covered, the classification of audiologists as suppliers of “other diagnostic tests” under Medicare payer policy, and non-coverage of certain audiologic management and treatment services. Nearly two decades of legislative efforts have not resulted in any substantial changes to U.S. health policy, while the need for audiology services has increased due to a growing demographic of older adults. The Medicare Audiologist Access and Services Act (MAASA) has been introduced in the 116th and 117th Congress and proposes amendments to the Social Security Act that would address statutory barriers to accessing hearing and balance care among Medicare beneficiaries and would recognize audiologists for their scope of practice within the Medicare program. Objectives of the present review are to provide a summary of statutes in the Social Security Act and Standard Occupational Classification system which affect audiologists, audiology services, and Medicare beneficiaries and to discuss previous and current legislative health policy efforts to address these statutory barriers to hearing and balance care access.
Future States for Hearing Care
Authors: Windmill Ian M. 
Published: June 2022

AbstractEvolutionary changes occur across health care, including within the hearing care delivery system. At times, the change is driven by external forces and thus elicits a reactive response. In contrast, developing a vision of a future state, and subsequently the strategies to achieve that vision, is a proactive and a preferred process. Using the reactive versus proactive framework, a future state built around the emergence of genetics as both an assessment tool and a treatment option is presented. In addition, a broad, consumer-centric vision for access to affordable and contemporary hearing care is presented that would result in an expanded and positive future state for hearing care services.
The Importance of Professional Advocacy at the State Level: A Coalition Model
Authors: Miller Erin L. , Roup Christina M. 
Published: June 2022

AbstractProfessional advocacy communicates a viewpoint for or against a policy or issue, and is used to influence change to public policy, legislation, and/or regulations. State audiology associations are perfectly positioned to organize advocacy efforts for the profession at the state level. Therefore, the purpose of this article is to review the types of advocacy available to state organizations and the steps for hiring a lobbyist. In addition, the article presents a unique advocacy model in which multiple audiology and speech-language pathology organizations in the state of Ohio joined to form the Ohio Speech and Hearing Governmental Affairs Coalition (OSHGAC). There are numerous advantages of an advocacy coalition, most importantly a shared financial responsibility. Finally, several examples of the OSHGAC recent legislative and regulatory advocacy efforts are reviewed.
Extended Computed Tomography Scale Images Provide a Detailed Assessment of Metal Screws and Are Superior to Standard Computed Tomography Scale Images and Digital Radiography at Detecting Experimentally Induced Screw Fractures In Vitro
Authors: Labrador Jose , Carrera Ines , Holdsworth Andy 
Published: June 2022

Abstract
Objectives (1) To compare the ability of standard computed tomography (CT) scale (SCTS) and extended CT scale (ECTS) images, produced using conventional CT technology, to provide detailed assessment of metal screws in vitro. (2) To assess how screw size, type, and orientation relative to the Z-axis of the gantry affect implant assessment. (3) To test the ability of SCTS, ECTS, and radiography to diagnose screw failure when there is negligible screw fragment displacement.
Study Design Part 1: 12 screws of different size, type, and composition were scanned in three orientations (parallel or 0°; oblique or 45°; and perpendicular or 90°) relative to the Z-axis of the gantry. SCTS and ECTS reconstructions were made for each screw, in each plane, to assess implant shape, structure, and diameter. Part 2: fatigue-failure was induced in four screws commonly used to stabilize canine humeral intracondylar fissures. Screws were then reassembled achieving grossly perfect apposition and alignment of the fragments. Ability to detect implant failure was tested using SCTS, ECTS, and radiography.
Results ECTS provided better screw assessment compared with SCTS resulting in clear visualization of the structure in 8/12 versus 0/12 screws and shape in 12/12 versus 11/12 screws; however, results were affected by screw size, type, and orientation. ECTS identified all in vitro screw fractures with negligible screw fragment displacement; however, success was affected by screw orientation: 4/4 fractures identified with a 90° angle, 1/4 for 45°, and 0/4 for 0°. SCTS and radiography did not identify any of them.
Conclusion The results indicate that ECTS reconstructions are useful for assessment of metal screws and for detection of nondisplaced screw fractures.

Abstract
Background Cancer staging information is an essential component of cancer research. However, the information is primarily stored as either a full or semistructured free-text clinical document which is limiting the data use. By transforming the cancer-specific data to the Observational Medical Outcome Partnership Common Data Model (OMOP CDM), the information can contribute to establish multicenter observational cancer studies. To the best of our knowledge, there have been no studies on OMOP CDM transformation and natural language processing (NLP) for thyroid cancer to date.
Objective We aimed to demonstrate the applicability of the OMOP CDM oncology extension module for thyroid cancer diagnosis and cancer stage information by processing free-text medical reports.
Methods Thyroid cancer diagnosis and stage-related modifiers were extracted with rule-based NLP from 63,795 thyroid cancer pathology reports and 56,239 Iodine whole-body scan reports from three medical institutions in the Observational Health Data Sciences and Informatics data network. The data were converted into the OMOP CDM v6.0 according to the OMOP CDM oncology extension module. The cancer staging group was derived and populated using the transformed CDM data.
Results The extracted thyroid cancer data were completely converted into the OMOP CDM. The distributions of histopathological types of thyroid cancer were approximately 95.3 to 98.8% of papillary carcinoma, 0.9 to 3.7% of follicular carcinoma, 0.04 to 0.54% of adenocarcinoma, 0.17 to 0.81% of medullary carcinoma, and 0 to 0.3% of anaplastic carcinoma. Regarding cancer staging, stage-I thyroid cancer accounted for 55 to 64% of the cases, while stage III accounted for 24 to 26% of the cases. Stage-II and -IV thyroid cancers were detected at a low rate of 2 to 6%.
Conclusion As a first study on OMOP CDM transformation and NLP for thyroid cancer, this study will help other institutions to standardize thyroid cancer–specific data for retrospective observational research and participate in multicenter studies.

AbstractThe coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2, has devastated every sphere of human society. Governments around the world implemented unprecedented policies designed to slow the spread of the disease and assistance to cope with its impacts. Such policies, however, are short-term and debates have ensued about what broader policies are needed in the post-COVID-19 era to ensure societies are better prepared for future pandemics. Public opinion concerning COVID-19 and the post-COVID-19 era is diverse, and the patterns in opinion are not well documented. Here we synthesized the opinions of 3731 research scholars throughout the world based on a survey. The highest consensus among respondents concerned the need for improving public health infrastructure and delivering economic support, whereas agreement concerning ecological aspects was low. The survey revealed three dimensions of thinking about COVID-19. The first dimension relates to public health and has widespread support. The second dimension relates to science-led policy development focusing on social justice and environmental governance, covering components of both ecology and economy. The third dimension covers the role of nature conservation in reducing the risk of pandemics. Although opinions differed with age, country of citizenship, and level of education, there is strong agreement on the need for global health equity and science-led public policy.
