The Doppler ultrasound is the most common technique for noninvasive quantification of blood flow, which, in turn, is of major clinical importance for the assessment of the cardiovascular condition. In this article, a method is proposed in which the vessel is imaged in the short axis, which has the advantage of capturing the whole flow profile while measuring the vessel area simultaneously. This view is easier to obtain than the longitudinal image that is currently used in flow velocity estima…

Sub-micrometer thin-film transistors (TFTs) are realized using multi-level imprint lithography. Amorphous indium gallium zinc oxide ( $\alpha $ -IGZO) TFTs with channel lengths as small as $0.7~\mu \text{m}$ , field-effect mobility of 10 cm2V−1s−1 and on/off ratio of circa 107 were integrated into a 1000-pixels per inch (ppi) TFT backplane array. The reduction of the number of patterning steps and the inherent self-registration of the most critical transistor layers on top of each other offer…

Firms increasingly rely upon trademarks, but management research exploiting trademark data is surprisingly limited. Reasons for this include data availability, awareness, and bias toward other sources, in particular patents. I demonstrate how imaginative scholars have used trademarks to capture several elements of how, when, and to what extent firms bring (new) products and services to the market. Their work can inspire further applications, particularly now that trademarks are becoming more …

Blind source separation (BSS) refers to a number of signal processing techniques that decompose a signal into several “source” signals. In recent years, BSS is increasingly employed for the suppression of clutter and noise in ultrasonic imaging. In particular, its ability to separate sources based on measures of independence rather than their temporal or spatial frequency content makes BSS a powerful filtering tool for data in which the desired and undesired signals overlap in the spectral do…

Within a time span of only a few months, the SARS-CoV-2 virus has managed to spread across the world. This virus can spread by close contact, which includes large droplet spray and inhalation of microscopic droplets, and by indirect contact via contaminated objects. While in most countries, supermarkets have remained open, due to the COVID-19 pandemic, authorities have ordered many other shops, restaurants, bars, music theaters and indoor sports centers to be closed. As part of COVID-19 (semi…

High-speed Rotational Angiography scans are prone to potential collisions between the C-arm X-ray system and the patient. A key factor during rotational angiography clinical workflow is thus the initial patient positioning to ensure a collision-free scan. The current practice for this involves multiple manual iterations of a low speed safety-run prior to the actual scan. Several iterations are often required before a scan is collision-free leading to a suboptimal clinical workflow. This work …

It is important to train clinicians to maintain and optimise maternal and neonatal outcomes after vaginal twin delivery. Simulation-based training provides opportunities for training in a realistic way without harming patients. The aim of this study is to evaluate the effect of simulation-based training concerning twin vaginal delivery on knowledge and comfort of obstetrician-gynaecologists.Obstetrician-gynaecologists participated in a twin vaginal delivery simulation between March 2018 and M…

The spread of COVID-19 in the whole world has put the humanity at risk. The resources of some of the largest economies are stressed out due to the large infectivity and transmissibility of this disease. Due to the growing magnitude of number of cases and its subsequent stress on the administration and health professionals, some prediction methods would be required to predict the number of cases in future. In this paper, we have used data-driven estimation methods like long short-term memory (…

Left ventricular assist devices (LVAD) provide cardiac support to patients with advanced heart failure. Methods that can directly measure remaining LV function following device implantation do not currently exist. Previous studies have shown that a combination of loading (LV pressure) and deformation (strain) measurements enables quantitation of myocardial work. We investigated the use of ultrasound (US) strain imaging and pressure-strain loop analysis in LVAD-supported hearts under different…

Business centers offer flexible shared workspaces and facilities to multiple organizations, which provide more freedom in where to interact with others. However, knowledge on where different types of organizational interactions take place in business centers and how this behavior is influenced is still lacking. Therefore, the aim of this study is to analyze the location choice for different types of face-to-face interactions. Data, collected by means of an experience sampling method (ESM), we…
