Emerging Jets

In this work, we propose a novel search strategy for new physics at the LHC that utilizes calorimeter jets that (i) are composed dominantly of displaced tracks and (ii) have many different vertices within the jet cone. Such emerging jet signatures are smoking guns for models with a composite dark sector where a parton shower in the dark sector is followed by displaced decays of dark pions back to SM jets. No current LHC searches are sensitive to this type of phenomenology. We perform a detailed simulation for a benchmark signal with two regular and two emerging jets, and present and implement strategies to suppress QCD backgrounds by up to six orders of magnitude. At the 14 TeV LHC, this signature can be probed with mediator masses as large as 1.5 TeV for a range of dark pion lifetimes, and the reach is increased further at the high-luminosity LHC. The emerging jet search is also sensitive to a broad class of long-lived phenomena, and we show this for a supersymmetric model with R-parity violation. Possibilities for discovery at LHCb are also discussed.Comment: 45 pages, 22 figures. v2: Typos fixed. v3: Minor modifications, references added, version accepted in JHEP.

The Targon®-PH Nail, an intramedullary fixator for unstable capital humeral fractures in the elderly patient: a retrospective study of 39 patients

The proximal humeral fracture occurs very often especially in elderly patients suffering from osteoporosis. Minimally invasive internal fixation with the Targon®-PH proximal humeral nail may lead to quick recovery. Thirty-nine patients with unstable humeral head fractures with two or four fragments were included into this study. The application of the humeral nail was achieved by deltoid split technique. Patients were followed-up clinically and radiologically including a Constant Score. The mean age was 72.9±3.3years of the male and 74.9±1.8years of the female patients. The subjective parameters of the Constant-Murley Score were significantly lowered in both the female and the male sample compared with the healthy side (female 30.0±1.1 vs. 33.7±0.7; P<0.05; and male 30.3±1.4 vs. 34.0±0.7; P<0.05). The objective parameters were significantly lowered also in both the female and the male sample compared with the non-operated side (female 34.5±2.0 vs. 45.2±1.1; P<0.001; and male 37.7±5.4 vs. 50.6±1.7; P<0.05). Even under lowered functionality, the subjective satisfaction was high; therefore, nailing of proximal humeral head fractures may represent a method for early functional recovery in elderly patient

Benchmarking guide : integrating public sector accounting and government finance statistics: addressing the differences between international public sector accounting standards, government finance statistics, & the European system of accounts

The PULSAR Program, launched in 2017, is a regional and country level program for 13 beneficiary countries in Europe and Central Asia. Its objective is to support the enhancement of public sector accounting and financial reporting frameworks, in line with international standards and in accordance with good practices, in order to improve government accountability, transparency, and performance. The objectives and scope of the PULSAR Program are jointly determined by the PULSAR Partners - Austria, Switzerland, and the World Bank – who also provide institutional support for its implementation and mobilize the resources needed for its activities. Beneficiary countries help shape the Program through regional cooperation platforms and input to two Communities of Practice focused on financial reporting frameworks and on education. The FINCOP supports government officials in developing reform strategies & roadmaps, and helps to define and implement improved legislation, standards, IT systems, and tools in the respective countries. The Benchmarking Guide for Integrating Public Sector Accounting and Government Finance Statistics aims to inform practitioners and public sector accounting reforms by highlighting the similarities and differences between International Public Sector Accounting Standards and Government Finance Statistics reporting guidelines such as the Government Finance Statistics Manual of the International Monetary Fund (GFSM 2014) and the European System of Accounts (ESA 2010). This Guide facilitates an integrated view of the two sets of reporting guidelines and outlines a process to more closely align them. It also discusses fundamental challenges and corresponding mitigation strategies. In the Guide’s presentation of key conceptual issues, care was taken to maintain consistency with the technical guidelines of the reference frameworks. Nevertheless, it is recommended that the original sources are consulted with regards to specific technical questions related to recognition, measurement, and disclosure under IPSAS and ESA 2010 or GFSM 2014

Avulsion of the Hamstring Muscle Group: A Follow-Up of 6 Adult Non-Athletes with Early Operative Treatment: A Brief Report

Background: Complete proximal avulsions of the hamstring muscle group may cause significant morbidity and loss of function. These pelvis-near musculoskeletal injuries are mostly acquired during sports activities in a hip flexion and knee extension. Here we present a study group of 6 middle-aged to elderly patients suffering a complete proximal hamstring avulsion and following early surgical refixation. Early surgical refixation leads to complete resumption of the activities of daily life without loss of function. Materials and methods: The 6 patients (3 men and 3 women) included in this study had an average age of 59.07±4.47years at the time of injury. All of them suffered a complete avulsion of the hamstring muscle group. Surgical refixation was accomplished with the corkscrew anchor refixation system (Arthrex Manufacturing, Inc., Naples, FL). The cases were retrospectively analyzed using a hip joint evaluation system, the Harris Hip Score, and radiological follow-up by magnetic resonance imaging (MRI). Data are given as mean±SEM. Student's t-test was used for normal distribution of the data. Results: The mean follow-up time was 31.83±18.9months (range: 10-118months). All patients were rated not to have a significant difference in function compared with the uninjured side. None of the patients suffered any handicaps resulting from surgery or the injury. A complete consolidation in all patients was observed in the follow-up MRI. Conclusions: Early surgical intervention and subsequent therapy in a complete hamstring avulsion injury may prevent loss of hip-joint stability and prevent the sequalae of degradative hip or vertebral event

UAV-Based forest health monitoring : a systematic review

CITATION: Ecke, S. et al. 2022. UAV-Based forest health monitoring : a systematic review. Remote Sensing, 14(13):3205, doi:10.3390/rs14133205.The original publication is available at https://www.mdpi.comIn recent years, technological advances have led to the increasing use of unmanned aerial vehicles (UAVs) for forestry applications. One emerging field for drone application is forest health monitoring (FHM). Common approaches for FHM involve small-scale resource-extensive fieldwork combined with traditional remote sensing platforms. However, the highly dynamic nature of forests requires timely and repetitive data acquisition, often at very high spatial resolution, where conventional remote sensing techniques reach the limits of feasibility. UAVs have shown that they can meet the demands of flexible operation and high spatial resolution. This is also reflected in a rapidly growing number of publications using drones to study forest health. Only a few reviews exist which do not cover the whole research history of UAV-based FHM. Since a comprehensive review is becoming critical to identify research gaps, trends, and drawbacks, we offer a systematic analysis of 99 papers covering the last ten years of research related to UAV-based monitoring of forests threatened by biotic and abiotic stressors. Advances in drone technology are being rapidly adopted and put into practice, further improving the economical use of UAVs. Despite the many advantages of UAVs, such as their flexibility, relatively low costs, and the possibility to fly below cloud cover, we also identified some shortcomings: (1) multitemporal and long-term monitoring of forests is clearly underrepresented; (2) the rare use of hyperspectral and LiDAR sensors must drastically increase; (3) complementary data from other RS sources are not sufficiently being exploited; (4) a lack of standardized workflows poses a problem to ensure data uniformity; (5) complex machine learning algorithms and workflows obscure interpretability and hinders widespread adoption; (6) the data pipeline from acquisition to final analysis often relies on commercial software at the expense of open-source tools.https://www.mdpi.com/2072-4292/14/13/3205Publisher's versio
