Propulsion at low Reynolds numbers is often studied by defining artificial microswimmers which exhibit a particular stroke. The disadvantage of such an approach is that the stroke does not adjust to the environment, in particular the fluid flow, which can diminish the effect of hydrodynamic interactions. To overcome this limitation, we simulate a microswimmer consisting of three beads connected by springs and dampers, using the self-developed waLBerla and <i>pe</i> framework based on the lattice Boltzmann method and the discrete element method...

OBJECTIVE/BACKGROUND: The Insomnia Severity Index (ISI) is a widely used self-report measure of insomnia symptoms. However, to date this measure has not been validated or well-characterized in veterans who have experienced traumatic brain injury (TBI). This study assessed the psychometric properties and convergent, divergent, construct, and discriminate validity of the ISI in veterans with a history of TBI. PARTICIPANTS: Eighty-three veterans with history of TBI were seen in the VA San Diego Healthcare System as part of a research protocol...

Impairments in visual perception are common after acquired brain injury (ABI) and adequate assessment is crucial for diagnosis and rehabilitation. However, there is no consensus yet on how to assess these disorders after ABI. The aim of the present study was to explore what measures are considered reasonable to be part of a test battery for the screening of a broad range of mid-level and higher-order visual perceptual disorders. A Delphi method was used to collect the opinions of 28 international multidisciplinary experts in visual perception in order to achieve consensus on the content of the test battery...

Tacrolimus (TAC, FK-506) and everolimus (EVE, RAD001) are immunosuppressors used to treat pediatric patients undergoing liver transplantation. Their hematic TDM by liquid chromatography became standard practice. However, it does not always reflect concentrations at their active site. Our aim was to develop and validate a new method for the simultaneous TAC and EVE quantification into target cells: Peripheral-Blood-Mononuclear-Cells (PBMCs). PBMCs were collected using Cell-Preparation-Tubes; cells number and MCV were evaluated by an automatic cell counter...

Second Harmonic Generation (SHG) has emerged as a highly sensitive probe of protein conformation. SHG can also be used to determine the tilt angle of an SHG-active moiety bound to a surface-adsorbed protein through polarization-dependent measurements. However, due to the coherent nature of SHG, interference occurs between the SHG produced by the SHG-active moieties and background sources at a solid-liquid interface, obscuring the signal of interest. In order to separate the protein-specific signal from the background signal, the phase difference between these two different sources of SHG must be determined...

PURPOSE: Multiband pulses are characterized by highly temporally modulated waveforms. Rapid phase or frequency modulation can be extremely demanding on the performance of radiofrequency (RF) pulse generation, which can lead to errors that can be avoided if pulses are restricted to amplitude modulation (AM) only. In this work, three existing multiband pulse design techniques are modified to produce AM waveforms. THEORY AND METHODS: Multiband refocusing pulses were designed using phase optimization, time shifting, and root flipping...

The determination of amino acids with the actions-like neurotransmitters or modulators have been increasingly important for diagnose in many neuropsychiatric diseases. A rapid and simple high performance liquid chromatography with fluorescence detection (HPLC-FLD) was developed for simultaneous determination of seven amino acids: aspartate (Asp), glutamate (Glu), serine (Ser), glutamine (Gln), glycine (Gly), taurine (Tau) and γ-aminobutyric acid (GABA). Homoserine (Hse) was used as an internal standard (IS)...

OBJECTIVE: The Beck Depression Inventory-II (BDI-II) is one of the most popular scales for evaluating the severity of depression in adolescents as well as adults. The prevalence of depression increases during adolescence, and it has shown a rapid increase with occurrence at an earlier age and a tendency to continue into adulthood. Data from an adolescent nonclinical sample provides us more information related to depressive symptoms as potential risk factors. The current study was designed to two objectives: 1) to analyze the reliability and validity the BDI-II among Korean adolescents and 2) to evaluate the factorial structure in a Korean nonclinical adolescent sample...

Over the course of more than 40 years, international research has consistently shown situational judgment tests (SJTs) to be a reliable and valid selection method for assessing a range of professional attributes. However, SJTs still represent a relatively new selection method within the medical profession, and as such it is to be expected that applicant reactions will vary. In this Expert Opinion piece, we respond to Najim et al's article "The situational judgement test: a student's worst nightmare" by highlighting three key clarifications...

BACKGROUND: Capacity building strategies are widely used to increase the use of research in policy development. However, a lack of well-validated measures for policy contexts has hampered efforts to identify priorities for capacity building and to evaluate the impact of strategies. We aimed to address this gap by developing SEER (Seeking, Engaging with and Evaluating Research), a self-report measure of individual policymakers' capacity to engage with and use research. METHODS: We used the SPIRIT Action Framework to identify pertinent domains and guide development of items for measuring each domain...

BACKGROUND: Model based analysis of human upper limb movements has key importance in understanding the motor control processes of our nervous system. Various simulation software packages have been developed over the years to perform model based analysis. These packages provide computationally intensive-and therefore off-line-solutions to calculate the anatomical joint angles from motion captured raw measurement data (also referred as inverse kinematics). In addition, recent developments in inertial motion sensing technology show that it may replace large, immobile and expensive optical systems with small, mobile and cheaper solutions in cases when a laboratory-free measurement setup is needed...

BACKGROUND: In this paper, a new method is presented that combines mechanical compliance effects with Poiseuille flow and push-out effects ("dead volume") in one single mathematical framework for calculating dosing errors in multi-infusion set-ups. In contrast to existing numerical methods, our method produces explicit expressions that illustrate the mathematical dependencies of the dosing errors on hardware parameters and pump flow rate settings. METHODS: Our new approach uses the Z-transform to model the contents of the catheter, and after implementation in Mathematica (Wolfram), explicit expressions are produced automatically...

BACKGROUND: The survivors after hip fracture often report severe pain and loss of physical functioning. The poor outcomes cause negative impact on the person's physical functioning and quality of life and put a financial burden on society. Rehabilitation is important to improve physical functioning after hip fracture. To maintain the continuity in rehabilitation we have an assumption that it is of utmost importance to continue and progress the functional training that already started at the hospital, while the patients are transferred to short-term stays in a nursing home before they are returning to home...
