Summary: In patients with dropped head syndrome (DHS), biomechanical analysis reveals shorter stride length, smaller peak hip-joint extension angle, and backward thorax tilt during level walking compared to healthy elderly. Additionally, DHS patients exhibit smaller peak ankle-joint plantar-flexion moment despite larger dorsiflexion angle. These kinematic and kinetic differences reflect the unique gait characteristics of DHS patients, including lower limb joint movements and thorax-pelvis alignment.

Summary: This research examines the benefits of salesperson hunting and farming orientations for organizations, as well as the factors that influence these benefits. Data from 391 salespeople at 50 firms indicate that adaptive selling behaviors mediate the relationship between the two customer engagement orientations (hunting and farming), with hunting orientation having a stronger impact on adaptive selling behaviors. The data also reveal that organizational control systems moderate these relationships, with outcome control strengthening the positive effect of hunting orientation and behavioral control strengthening the positive effect of farming orientation on adaptive selling behaviors.

Summary: This study examined the hemodynamic changes during tactile vibration stimuli in fullterm infants and neonates up to 10 months of age using functional near-infrared spectroscopy. The amplitude of the normalized oxygenated hemoglobin showed an effect of age, while the time to peak was not affected. These results may reflect developmental changes in neural activity, vasculature, and blood oxygenation.

Summary: In neural networks, there is a tradeoff between sensitivity and stability. Dopamine neurons in the fruit fly's head direction network are specifically active when the fly turns to change its head direction, and their activity scales with rotational speed. Pairing dopamine release with a visual cue strengthens the cue's influence on head direction cells, while inhibiting these neurons decreases the influence of the cue. This mechanism allows for accelerated learning when rich head direction information is available, while protecting stored information at other times.

Summary: This paper presents a touchless assistive system method called Touchless Head-Control (THC) for computer cursor control based on head pose captured with an RGB camera. The convolutional neural networks are used to estimate head pose angles, and the mouse pointer or cursor is moved based on head movement and face position. The interaction design evaluation measured target selection accuracy, travel time, and path efficiency.

Summary: Feedback control of neural stimulation can maintain upright seated posture and facilitate trunk movements necessary for completing reaching tasks in individuals with spinal cord injury (SCI). Replication of these findings on a larger number of subjects is necessary for generalization to the SCI population.

Summary: Due to the vulnerability of eye saccades, people find it challenging to control smart systems with complex gaze gestures. This paper proposes a new set of eye gaze points and head orientation angles as new sequences to recognize complex gaze gestures, which outperformed conventional methods.

Summary: The study found that cortical oscillations play a role in integrating locomotor demands during primate arboreal locomotion, with beta and gamma waves reflecting different processes in movement adjustments. Modulation of gamma ERS by substrate orientation and epoch suggests close tuning to movement dynamics and biomechanical demands, while beta ERD is modulated by gait, illustrating contribution to movement sequence and coordination. At rest, modulation of beta power by substrate orientation highlights its role in sensorimotor processes for postural maintenance.

Summary: Running causes undulations in animal trunk and head rotations need to be stabilised for balance. Experimental measurements on Acanthodactylus pardalis lizards show that head stabilisation in pitch direction is lower compared to yaw and roll direction. Despite hypotheses about vestibular system sensitivity, a Fluid-Structure Interaction model suggests that roll sensitivity is lowest, possibly due to neurological nonlinearities. However, the elongated head shape reduces the moment of inertia in roll direction, making head stabilisation easier in this direction.

Summary: This study investigates the genomic mechanisms underlying interspecies differences in stromal invasibility, identifying transcription factors GATA2 and TFDP1 as key regulators of fibroblast invasibility. These findings provide insights into the regulation of placental invasion, wound healing, and cancer dissemination through targeting stromal characteristics.

Summary: Wearing complete dentures can improve head stability during walking in edentulous older adults, thus contributing to walking stability. This study found that the variance values and peak-to-peak values of acceleration and angle rate were significantly larger without dentures compared to with dentures.

Summary: This study introduces a wearable device that measures the posture of different sections of the spine and provides feedback to users through a vibration unit, effectively reducing low back pain and improving postural control. Initial clinical pilot study results show great potential in alleviating pain and enhancing postural awareness in patients with low back pain.
