Abstract In response to growing evidence that repetitive head impact exposure and concussions can lead long-term health consequences, many research studies are attempting quantify the frequency severity of impacts incurred in various sports occupations. The most popular apparatus for doing so is instrumented mouthguard (iMG). While these devices hold greater promise kinematic accuracy than their helmet-mounted predecessors, data artifacts related iMG decoupling still plague results. We...
Poor sleep quality is associated with age-related cognitive decline, and whether reversal of these alterations possible unknown. In this study, we report how deprivation (SD) affects hippocampal representations, patterns, memory in young old mice. After training a hippocampus-dependent object-place recognition (OPR) task, control animals ad libitum, although experimental undergo 5 h SD, followed by recovery sleep. Young controls SD mice exhibit successful OPR memory, whereas are impaired....
Abstract Instrumented head acceleration measurement devices are commonly used in research studies to determine exposure certain populations. mouthguards pair directly the user’s teeth and offer six-degree-of-freedom measurements. Though many have recently these devices, post-processing techniques vary by study. Other attempted label impact quality or coupling status, also with varying methods. This study sought compare effect of labeling methods on reported distribution characteristics...
Many recent studies have used boil-and-bite style instrumented mouthguards to measure head kinematics during impact in sports. Instrumented promise greater accuracy than their predecessors because of superior ability couple directly the skull. These been validated lab and on field, but little is known about effects decoupling impact. Decoupling can occur for various reasons, such as poor initial fit, wear-and-tear, or excessive forces. To understand how influences measured kinematic error,...
This paper presents a novel instrumentation system for on-line nonintrusive detection of wood pellets in pneumatic conveying pipelines using vibration and acoustic sensors. The captures the sound generated by collisions between biomass particles pipe wall. Time-frequency analysis technique is used to eliminate environmental noise from signal, extract information about collisions, identify presence pellets. Experiments were carried out on an industrial pipeline assess effectiveness...
This study examined the contributions of tongue tip (TT), body (TB), and lateral (TL) sensors in electromagnetic articulography (EMA) measurement American English alveolar consonants. Thirteen adults produced /ɹ/, /l/, /z/, /d/ /ɑCɑ/ syllables while being recorded with an EMA system. According to statistical analysis sensor movement results a machine classification experiment, TT contributed most consonant differences, followed by TB. The TL played complementary role, particularly for...
Respiratory volumes during phonation of a series voiced and voiceless fricatives plosives placed within carrier phrase were measured in 20 normal adult subjects. The purpose was to (1) determine whether consonant type influences respiratory volume (2) intraoral pressure differences among voiced-voiceless consonants could be reflection speech. results indicate that utilize substantially larger air than their cognates. data also suggest pressures may influenced more by energy losses caused...
Abstract When verifying the correctness of single‐digit multiplication problems, children and adults show a robust ERP effect thought to reflect similar cognitive processes across groups. Recent studies suggest that this is instead modulation negative‐going N400 component in children, reflecting access semantic memory, positive‐going P300 adults, stimulus categorization. However, relative difference amplitude same for both components, more positive correct than incorrect solutions,...
In order to investigate the articulatory processes involved in producing Japanese /r/, we obtained speech recordings for native talkers of standard using an electromagnetic articulography (EMA) system. Each talker produced repetitions /r/ a carrier phrase designed contrast syllable (CV and VCV VCV) vowel (/a/, /i/, /u/, /e/, /o/) contexts. Kinematic were made tongue (tip, TT; dorsum, TD; body, TB; left lateral, TLL; right TRL) lower lip/jaw (LL) sensors. We measured TT vertical displacement,...
This paper proposes a novel approach to online automatic detection of the presence large biomass particles in pneumatic conveying pipeline using an acoustic emission sensor and time-frequency analysis techniques. The is used capture sound emitted from collisions between pipe wall. Time-frequency technique eliminate environmental noise signal, extract revealing information about collisions, identify particles. together with its signal conditioning unit integrated into compact enclosure, which...
<div>Head injuries account for 15% of snowsport-related injuries, and the majority head impacts occur against ice or snow, low-friction surfaces. Therefore, this study aimed to evaluate how surface friction affects snowsport helmets’ oblique impact kinematics. Ten helmet models were impacted using an drop tower with a 45-degree anvil NOCSAE headform, at three locations, two conditions, speed 5.0 m/s. Our findings indicate that peak linear acceleration, rotational velocity during...
Summary Age-related changes in sleep patterns have been linked to cognitive decline. Specifically, increasing age is associated with fragmentation of and wake cycles. However, it remains unknown if improvements architecture can ameliorate cellular deficits. We evaluated how following restriction affected hippocampal representations memory young old mice. After training a hippocampus- dependent object/place recognition task, control animals were allowed ad libitum , while experimental...
