  text: <jats:p>Laboratory studies have limitations in screening for anterior cruciate
    ligament (ACL) injury risk due to their lack of ecological validity. Machine learning
    (ML) methods coupled with wearable sensors are state-of-art approaches for joint
    load estimation outside the laboratory in athletic tasks. The aim of this study
    was to investigate ML approaches in predicting knee joint loading during sport-specific
    agility tasks. We explored the possibility of predicting high and low knee abduction
    moments (KAMs) from kinematic data collected in a laboratory setting through wearable
    sensors and of predicting the actual KAM from kinematics. Xsens MVN Analyze and
    Vicon motion analysis, together with Bertec force plates, were used. Talented
    female football (soccer) players (n = 32, age 14.8 ± 1.0 y, height 167.9 ± 5.1
    cm, mass 57.5 ± 8.0 kg) performed unanticipated sidestep cutting movements (number
    of trials analyzed = 1105). According to the findings of this technical note,
    classification models that aim to identify the players exhibiting high or low
    KAM are preferable to the ones that aim to predict the actual peak KAM magnitude.
    The possibility of classifying high versus low KAMs during agility with good approximation
    (AUC 0.81–0.85) represents a step towards testing in an ecologically valid environment.</jats:p>

  text: In a punch-bending machine, wire products are manufactured for a wide range
    of industrial sectors, such as the electronics industry. The raw material for
    this process is flat wire made of high-strength steel. During the manufacturing
    process of the flat wire, residual stresses and plastic deformations are induced
    into the wire. These residual stresses and deformations fluctuate over the length
    of the semi-finished product and have a negative effect on the final product quality.
    Straightening machines are used to reduce this influence to a minimum. So far,
    the adjustment of a straightening machine has been performed manually, which is
    a lengthy and complex task even for an experienced worker. This inevitably leads
    to the use of inefficient straightening strategies and causes high rejection rates
    in the entire production process. Due to a lack of sensor information from the
    straightening operation, application of modern feedback control methods has not
    been practicable. This paper presents a novel design for a straightening machine
    with an integrated, precise straightening force measurement. By simultaneously
    monitoring the position of the straightening rollers, state variables of the straightening
    operation can be derived. Additionally, a tension control for feeding the flat
    wire is introduced. This is implemented to mitigate the disturbing effects caused
    by irregularities in the wire-feeding process. In the results of this article,
    the high precision of the developed force measurement design and its possible
    applications are shown.

  text: '<jats:p>The aim of the present study was to investigate if the presence of
    anterior cruciate ligament (ACL) injury risk factors depicted in the laboratory
    would reflect at-risk patterns in football-specific field data. Twenty-four female
    footballers (14.9 ± 0.9 year) performed unanticipated cutting maneuvers in a laboratory
    setting and on the football pitch during football-specific exercises (F-EX) and
    games (F-GAME). Knee joint moments were collected in the laboratory and grouped
    using hierarchical agglomerative clustering. The clusters were used to investigate
    the kinematics collected on field through wearable sensors. Three clusters emerged:
    Cluster 1 presented the lowest knee moments; Cluster 2 presented high knee extension
    but low knee abduction and rotation moments; Cluster 3 presented the highest knee
    abduction, extension, and external rotation moments. In F-EX, greater knee abduction
    angles were found in Cluster 2 and 3 compared to Cluster 1 (p = 0.007). Cluster
    2 showed the lowest knee and hip flexion angles (p &lt; 0.013). Cluster 3 showed
    the greatest hip external rotation angles (p = 0.006). In F-GAME, Cluster 3 presented
    the greatest knee external rotation and lowest knee flexion angles (p = 0.003).
    Clinically relevant differences towards ACL injury identified in the laboratory
    reflected at-risk patterns only in part when cutting on the field: in the field,
    low-risk players exhibited similar kinematic patterns as the high-risk players.
    Therefore, in-lab injury risk screening may lack ecological validity.</jats:p>'

  text: <jats:p>Quartz crystal microbalance with dissipation monitoring (QCM-D) is
    a well-established technique for studying soft films. It can provide gravimetric
    as well as nongravimetric information about a film, such as its thickness and
    mechanical properties. The interpretation of sets of overtone-normalized frequency
    shifts, ∆f/n, and overtone-normalized shifts in half-bandwidth, ΔΓ/n, provided
    by QCM-D relies on a model that, in general, contains five independent parameters
    that are needed to describe film thickness and frequency-dependent viscoelastic
    properties. Here, we examine how noise inherent in experimental data affects the
    determination of these parameters. There are certain conditions where noise prevents
    the reliable determination of film thickness and the loss tangent. On the other
    hand, we show that there are conditions where it is possible to determine all
    five parameters. We relate these conditions to the mathematical properties of
    the model in terms of simple conceptual diagrams that can help users understand
    the model’s behavior. Finally, we present new open source software for QCM-D data
    analysis written in Python, PyQTM.</jats:p>

  text: <jats:p>Sport-related concussions (SRC) are characterized by impaired autonomic
    control. Heart rate variability (HRV) offers easily obtainable diagnostic approaches
    to SRC-associated dysautonomia, but studies investigating HRV during sleep, a
    crucial time for post-traumatic cerebral regeneration, are relatively sparse.
    The aim of this study was to assess nocturnal HRV in athletes during their return
    to sports (RTS) after SRC in their home environment using wireless wrist sensors
    (E4, Empatica, Milan, Italy) and to explore possible relations with clinical concussion-associated
    sleep symptoms. Eighteen SRC athletes wore a wrist sensor obtaining photoplethysmographic
    data at night during RTS as well as one night after full clinical recovery post
    RTS (&gt;3 weeks). Nocturnal heart rate and parasympathetic activity of HRV (RMSSD)
    were calculated and compared using the Mann–Whitney U Test to values of eighteen;
    matched by sex, age, sport, and expertise, control athletes underwent the identical
    protocol. During RTS, nocturnal RMSSD of SRC athletes (Mdn = 77.74 ms) showed
    a trend compared to controls (Mdn = 95.68 ms, p = 0.021, r = −0.382, p adjusted
    using false discovery rate = 0.126) and positively correlated to “drowsiness”
    (r = 0.523, p = 0.023, p adjusted = 0.046). Post RTS, no differences in RMSSD
    between groups were detected. The presented findings in nocturnal cardiac parasympathetic
    activity during nights of RTS in SRC athletes might be a result of concussion,
    although its relation to recovery still needs to be elucidated. Utilization of
    wireless sensors and wearable technologies in home-based settings offer a possibility
    to obtain helpful objective data in the management of SRC.</jats:p>

  text: '<jats:p>The response of the quartz crystal microbalance (QCM, also: QCM-D
    for “QCM with Dissipation monitoring”) to loading with a diverse set of samples
    is reviewed in a consistent frame. After a brief introduction to the advanced
    QCMs, the governing equation (the small-load approximation) is derived. Planar
    films and adsorbates are modeled based on the acoustic multilayer formalism. In
    liquid environments, viscoelastic spectroscopy and high-frequency rheology are
    possible, even on layers with a thickness in the monolayer range. For particulate
    samples, the contact stiffness can be derived. Because the stress at the contact
    is large, the force is not always proportional to the displacement. Nonlinear
    effects are observed, leading to a dependence of the resonance frequency and the
    resonance bandwidth on the amplitude of oscillation. Partial slip, in particular,
    can be studied in detail. Advanced topics include structured samples and the extension
    of the small-load approximation to its tensorial version.</jats:p>'

  text: <jats:p>The development of renewable energies and smart mobility has profoundly

  text: <jats:p>A quartz crystal microbalance (QCM) is described, which simultaneously
    determines resonance frequency and bandwidth on four different overtones. The
    time resolution is 10 milliseconds. This fast, multi-overtone QCM is based on
    multi-frequency lockin amplification. Synchronous interrogation of overtones is
    needed, when the sample changes quickly and when information on the sample is
    to be extracted from the comparison between overtones. The application example
    is thermal inkjet-printing. At impact, the resonance frequencies change over a
    time shorter than 10 milliseconds. There is a further increase in the contact
    area, evidenced by an increasing common prefactor to the shifts in frequency,
    Δf, and half-bandwidth, ΔΓ. The ratio ΔΓ/(−Δf), which quantifies the energy dissipated
    per time and unit area, decreases with time. Often, there is a fast initial decrease,
    lasting for about 100 milliseconds, followed by a slower decrease, persisting
    over the entire drying time (a few seconds). Fitting the overtone dependence of
    Δf(n) and ΔΓ(n) with power laws, one finds power-law exponents of about 1/2, characteristic
    of semi-infinite Newtonian liquids. The power-law exponents corresponding to Δf(n)
    slightly increase with time. The decrease of ΔΓ/(−Δf) and the increase of the
    exponents are explained by evaporation and formation of a solid film at the resonator
    surface.</jats:p>

  text: <jats:p>A mobile system that can detect viruses in real time is urgently needed,
    due to the combination of virus emergence and evolution with increasing global
    travel and transport. A biosensor called PAMONO (for Plasmon Assisted Microscopy
    of Nano-sized Objects) represents a viable technology for mobile real-time detection
    of viruses and virus-like particles. It could be used for fast and reliable diagnoses
    in hospitals, airports, the open air, or other settings. For analysis of the images
    provided by the sensor, state-of-the-art methods based on convolutional neural
    networks (CNNs) can achieve high accuracy. However, such computationally intensive
    methods may not be suitable on most mobile systems. In this work, we propose nanoparticle
    classification approaches based on frequency domain analysis, which are less resource-intensive.
    We observe that on average the classification takes 29    μ   s per image for
    the Fourier features and 17    μ   s for the Haar wavelet features. Although the
    CNN-based method scores 1–2.5 percentage points higher in classification accuracy,
    it takes 3370    μ   s per image on the same platform. With these results, we
    identify and explore the trade-off between resource efficiency and classification
    performance for nanoparticle classification of images provided by the PAMONO sensor.</jats:p>

  text: Capacitive sensors are the most commonly used devices for the detection of
    humidity because they are inexpensive and the detection mechanism is very specific
    for humidity. However, especially for industrial processes, there is a lack of
    dielectrics that are stable at high temperature (>200 °C) and under harsh conditions.
    We present a capacitive sensor based on mesoporous silica as the dielectric in
    a simple sensor design based on pressed silica pellets. Investigation of the structural
    stability of the porous silica under simulated operating conditions as well as
    the influence of the pellet production will be shown. Impedance measurements demonstrate
    the utility of the sensor at both low (90 °C) and high (up to 210 °C) operating
    temperatures.

  text: We report on the synthesis and CO gas-sensing properties of mesoporous tin(IV)
    oxides (SnO2). For the synthesis cetyltrimethylammonium bromide (CTABr) was used
    as a structure-directing agent; the resulting SnO2 powders were applied as films
    to commercially available sensor substrates by drop coating. Nitrogen physisorption
    shows specific surface areas up to 160 m2·g-1 and mean pore diameters of about
    4 nm, as verified by TEM. The film conductance was measured in dependence on the
    CO concentration in humid synthetic air at a constant temperature of 300 °C. The
    sensors show a high sensitivity at low CO concentrations and turn out to be largely
    insensitive towards changes in the relative humidity. We compare the materials
    with commercially available SnO2-based sensors.
