A sea-wave-dynamics monitoring radar based on propagation characteristics of echo signals

As human's marine activities, such as marine aquaculture, ocean shipping and coastal facilities construction, flourished world-widely, it is required to monitor the sea-wave dynamics timely and accurately. The radar introduced in this paper, namely “Sea-wave-dynamics Monitoring and Imaging System (SMIS)”, working in the S-band at the center frequency of 3.1 GHz, is applicable to retrieving sea-wav

Affordable Quality of Service Assessment for Cellular-Connected UAV Communications

In recent years, Unmanned Aerial Vehicles (UAVs)have been used extensively in military and civilian fields, making the research on cellular-connected UAVs a popular topic forFifth Generation (5G) and beyond communications. In order to support the increasing amount of applications, it is essential to evaluate the performance of UAV communications. In this work, the end-to-end delay, packet success

Dynamic mmWave Channel Emulation in a Cost-Effective MPAC with Dominant-Cluster Concept

Millimeter-Wave (mmWave) massive multiple-input multiple-output (MIMO) has been considered as a key enabler for the fifth-generation (5G) communications. It is essential to design and test mmWave 5G devices under various realisticscenarios since the radio propagation channels pose intrinsic limitations on the performance. This requires emulating realistic dynamic mmWave channels in a reproducible

Diabetes Mellitus as a Risk Factor for Trigger Finger – a Longitudinal Cohort Study Over More Than 20 Years

Background and Aim: Trigger finger (TF) or stenosing tenosynovitis has been associated with diabetes mellitus (DM), although today’s knowledge is mostly based on cross-sectional and case-control studies. Thus, the aim of the present population-based cohort study over more than 20 years was to investigate DM as a risk factor for TF.Methods: Data from Malmö Diet and Cancer Study (MDCS), including 30

Low energy soft x-ray emission spectrometer at BL-09A in NewSUBARU

A compact soft X-ray emission spectrometer for the energy region of 50-600 eV has been designed and constructed for the long undulator beamline BL-09A in the NewSUBARU synchrotron radiation (SR) facility. The optical design of the spectrometer is based on a grazing incidence flat-field spectrometer using a valid line-spacing grating. The average groove density of the grating is 2000 L/mm, and the

Synthesis of new monofunctional and oligofunctional oxetane acetals

Derivatives of 3-ethyl-3-(hydroxymethyl)oxetane (trimethylolpropane oxetane), potentially useful in cationic UV-curable formulations, were prepared by the simple acid-catalyzed addition of alcohols to 1-alkenyl ethers. Examples include several difunctional oxetane derivatives along with one fluorinated and one acryloylated oxetane derivative. These new materials may find use as reactive diluents o

The complex multi-sectoral impacts of drought : Evidence from a mountainous basin in the Central Spanish Pyrenees

We analyzed the impacts of drought severity on a variety of sectors in a topographically complex basin (the upper Aragón basin 2181 km2) in the Central Spanish Pyrenees. Using diverse data sources including meteorological and hydrological observations, remote sensing and tree rings, we analyze the possible hydrological implications of drought occurrence and severity on water availability in variou

Combined assessment of tuberculosis case notification rate and infection control at health facilities of Dale districts, Sidama Zone, Southern Ethiopia

Background Mycobacterium tuberculosis (TB) is the deadliest disease that claims millions of deaths globally. Ethiopia is among the countries heavily hit by the disaster. Despite the effective directly observed treatment and TB infection control (TBIC) measures provided by the world health organization (WHO), the rate of new cases increased daily throughout the country. Healthcare workers (HCWs) ar

Factors influencing concordance of pd-l1 expression between biopsies and cytological specimens in non-small cell lung cancer

PD-L1 expression assessed by immunohistochemical staining is used for the selection of immunotherapy in non-small cell lung cancer (NSCLC). Appropriate validation of PD-L1 expression in cytology specimens is important as cytology is often the only diagnostic material in NSCLC. In a previous study comprising two different cohorts of paired biopsies and cytological specimens, we found a fairly good

Validated prediction model for positive resection margins in breast-conserving surgery based exclusively on preoperative data

BACKGROUND: Positive margins after breast-conserving surgery (BCS) and subsequent second surgery are associated with increased costs and patient discomfort. The aim of this study was to develop a prediction model for positive margins based on risk factors available before surgery. METHODS: Patients undergoing BCS for in situ or invasive cancer between 2015 and 2016 at site A formed a development c

An international, multistakeholder survey about metadata awareness, knowledge, and use in scholarly communications

The Metadata 2020 initiative is an ongoing effort to bring various scholarly communications stakeholder groups together to promote principles and standards of practice to improve the quality of metadata. To understand the perspectives and practices regarding metadata of the main stakeholder groups (librarians, publishers, researchers, and repository managers), we conducted a survey during summer 2

Physics informed stochastic grey-box model of the flow-front in a vacuum assisted resin transfer moulding process with missing data

Real-time fault monitoring and control of the Vacuum Assisted Resin Transfer Moulding production process requires knowledge of the position of the epoxy flow-front inside the mould. Therefore, a fast and accurate flow-front tracking system is highly prized. Physics-informed grey-box models deliver a good trade-off between high fidelity and data-driven black-box models for designing such a flow-fro

Extramedullary Cavernous Hemangioma with Intradural and Extradural Growth and Clinical Symptoms of Brown-Séquard Syndrome: : Case Report and Review of the Literature

Background: Primary spinal tumors are rare. Symptoms depend on the size and location of the tumor.Case description: A patient presented with a rare clinical finding, Brown-Séquard syndrome. The symptoms were caused by an extramedullary tumor compressing on the thoracic spinal cord. Pathologic examination showed cavernous hemangioma with growth both intradurally and extradurally.Conclusions: This i

Use of 3 Dimensional Models and Navigation System in Preparation for Brain Surgery

This paper shows the advantage of using both 3d models and surgical navigation system when preparing and planning complex brain surgery. The novel clinical process introduced here combine CT and MRI images in special computer program where the regions of interest are isolated e.g. the skull base, tumor and other soft tissue. A 3D model is calculated from the segmented masks and printed using Rapid

Solitary retroperitoneal ganglioneuroma

Retroperitoneal tumours rarely cause significant symptoms, therefore they are frequently diagnosed incidentally. Ganglioneuroma is a rare tumour that most often present in the posterior mediastinum or the retroperitoneal cavity. In the present case, a solitary ganglioneuroma is diagnosed in the retroperitoneum in an young healthy male, a rather typical presentation of this benign tumour.
