The proposed assay has shown an excellent selective fluorescence response toward Cd2+ ions over other ions like Al3+, Pb2+, Zn2+, Co2+, K+, Na+ and Sr2+. The fluorescence emission intensity of the probe is slightly affected by competing ions. In optimum pH value, 4, the limit of detection and linear concentration range were 0.05 nM and 0.1-1.5 nM, respectively. Additionally, the extraordinary output signal of β-CD-HQ was utilized to investigate the logic behavior of β-CD-HQ in the aqueous media. Accordingly, a solid support logic circuit was made by producing the fluorescence output signal under the stimulation of Cd2+ ions and tetracycline as inputs. © 2020 IOP Publishing Ltd.In in vivo postsurgery monitoring, the use of wireless biodegradable implantable sensors has gained and is gaining a lot of interest, particularly in the case of monitoring for a short period of time. Indeed, the employment of biodegradable materials would allow to circumvent a secondary surgery for the devices removal. Additionally, the use of wireless communication for the data elaboration would consent to avoid the need of transcutaneous wires. In this manner it would be possible to prevent possible inflammation and infections associated with long-term and not wireless implants. It is expected that microfabricated biodegradable sensors can play a strong impact in acute or transient biomedical applications. However, the design of a high-performing electronic system, both fully biodegradable and wireless, is a very complex issue, particularly at small scales. The associated technologies are still in their infancy step and they should be more deeply and extensively investigated in animal models and, successively, in humans, to be clinically implemented. In this context, the present manuscript is aimed to provide a complete overview about wireless biodegradable implantable sensors, covering from the vital signs to be monitored, the involved wireless technologies, the biodegradable materials used for the production of the devices, the designed devices and their applications. Particularly both their adavantages and drawbacks are highlighted and the key challenges to be faced up, mainly associated to the fabrication techniques, and the control over degradation kinetics and biocompatibility of the device, are reported and discussed. © 2020 IOP Publishing Ltd.Transport of electrons at high electric fields is investigated in intrinsic three-dimensional Dirac semimetal cadmium arsenide, considering the scattering of electrons from acoustic and optical phonons. Screening and hot phonon effect are taken in to account. Expressions for the hot electron mobility μ and power loss P are obtained as a function of electron temperature T_e. The dependence of drift velocity v_d on electric field E and electron density n_e has been studied. Hot phonon effect is found to set in the saturation of v_d at relatively low E and to significantly degrade its magnitude. MT-802 The drift velocity is found to saturate at a value v_ds ~ 10^7 cm/s and it is weakly dependent on n_e. A large saturation current density ~ 10^6 A/cm^2 is predicted. © 2020 IOP Publishing Ltd.During play, ice hockey goaltenders routinely dehydrate through sweating and lose ≥2% body mass, which may impair thermoregulation and performance. PURPOSE This randomized, crossover study examined the effects of mild dehydration on goaltender on-ice thermoregulation, heart rate, fatigue, and performance. METHODS Eleven goaltenders played a 70-minute scrimmage followed by a shootout and drills to analyze reaction time and movements. On ice, they either consumed no fluid (NF) and lost 2.4% (0.3%) body mass or maintained body mass with water (WAT) or a carbohydrate-electrolyte solution (CES). Save percentage, rating of perceived exertion, heart rate, and core temperature were recorded throughout, and a postskate questionnaire assessed perceived fatigue. RESULTS Relative to NF, intake of both fluids decreased heart rate (interaction P = .03), core temperature (peak NF = 39.0°C [0.1°C], WAT = 38.6°C [0.1°C], and CES = 38.5°C [0.1°C]; P = .005), and rating of perceived exertion in the scrimmage (post hoc P less then .04), as well as increasing save percentage in the final 10 minutes of scrimmage (NF = 75.8% [1.9%], WAT = 81.7% [2.3%], and CES = 81.3% [2.3%], post hoc P less then .04). In drills, movement speed (post hoc P less then .05) and reaction time (post hoc P less then .04) were slower in the NF versus both fluid conditions. Intake of either fluid similarly reduced postskate questionnaire scores (condition P less then .0001). Only CES significantly reduced rating of perceived exertion in drills (post hoc P less then .05) and increased peak movement power versus NF (post hoc P = .02). Shootout save percentage was similar between conditions (P = .37). CONCLUSIONS Mild dehydration increased physiological strain and fatigue and decreased ice hockey goaltender performance versus maintaining hydration. Also, maintaining hydration with a CES versus WAT may further reduce perceived fatigue and positively affect movements.Footwear bending stiffness is known to positively affect performance in agility maneuvers due to improved energy storage and propulsion based on a stiffer foot-shoe complex. However, the functional properties of the forefoot and midfoot differ. Therefore, the present study investigates the effect of the interface of longitudinal bending stiffness and the ratio of forefoot to midfoot bending stiffness on agility performance and foot biomechanics. A total of 18 male soccer players performed 2 agility tasks in footwear conditions that were systematically modified in forefoot and midfoot bending stiffness. Results revealed that higher longitudinal bending stiffness caused more foot exorotation at the initial ground contact (P less then .05), less torsion (P less then .001), and an anterior shift in the point of force application during push off (P = .01). In addition, the authors observed decreased forefoot bending (P less then .05) and increased torsion (P less then .01) in footwear with a higher forefoot-midfoot ratio.
