Résumé :
We recently introduced a method that allows the controlled deposition of nanoscale metallic patterns at defined locations using the tip of an atomic force microscope (AFM) as a “mechano-electrochemical pen”, locally activating a passivated substrate surface for site-selective electrochemical deposition. Here, we demonstrate the reversibility of this process and study the long-term stability of the resulting metallic structures. The remarkable stability for more than 1.5 years under ambient air without any observable changes can be attributed to self-passivation. After AFM-activated electrochemical deposition of copper nanostructures on a polycrystalline gold film and subsequent AFM imaging, the copper nanostructures could be dissolved by reversing the electrochemical potential. Subsequent AFM-tip-activated deposition of different copper nanostructures at the same location where the previous structures were deleted, shows that there is no observable memory effect, i.e., no effect of the previous writing process on the subsequent writing process. Thus, the four processes required for reversible information storage, “write”, “read”, “delete” and “re-write”, were successfully demonstrated on the nanometer scale.

Résumé :
A reversible bending phenomenon of Si3N4 nanowires on the conductive carbon–formalin microgrid under an illumination of electron beam was observed using a transmission electron microscope. The nanowires exhibit high flexibility. The bending deflection is approximately proportional to the square of the current density (J) of the electron beam. The bending strength of Si3N4 nanowire is much higher than that of bulk Si3N4 materials. The force that bent the nanowires may be an electrostatic force.

Résumé :
Motivated by recent studies on reversible adhesion mechanisms of geckos and insects, we investigate the effect of pre-tension on the orientation-dependent adhesion strength of an elastic tape adhering on a substrate. Our analysis shows that the pre-tension can significantly increase the peel-off force at small peeling angles while decreasing it at large peeling angles, leading to a strongly reversible adhesion. More interestingly, we find that there exists a critical value of pre-tension beyond which the peel-off force plunges to zero at a force-independent critical peeling angle. We further show that the level of pre-tension required for such force-independent detachment at a critical angle can be induced by simply dragging a spatula pad along a substrate at sufficiently low angles. These results provide a feasible explanation of relevant experimental observations on gecko adhesion and suggest possible strategies to design strongly reversible adhesives via pre-tension.

Résumé :
We aimed to study the long-term sinus reversion rate and recovery of left atrial function after modified surgical radiofrequency ablation for permanent atrial fibrillation caused by mitral valve disease. From March 2014 to May 2020, 35 patients who underwent modified surgical radiofrequency ablation during cardiac valve surgery in our hospital were selected as the study group, and 25 normal individuals without cardiac structural changes were selected as the control group. The time of modified surgical radiofrequency ablation and long-term sinus reversion rate were measured, and left atrial anteroposterior, superoinferior, left and right diameters, left atrial ejection fraction, left atrial filling index, and left atrial ejection force were measured before and 6 months after surgery. The mean ablation time was 23.2 min, and the long-term sinus reversion rate was 80.0%. The left atrium diameter decreased and the left atrium ejection fraction increased after the operation ( P < 0.05 ). The left atrium filling index and ejection force were significantly increased in 28 patients with sinus reversion ( P < 0.05 ). The decrease in left atrial diameter and the increase in left atrial ejection fraction were correlated with sinus conversion after surgery ( P < 0.05 ). The modified operation is simple, the curative effect is definite, and the sinus reversion rate is high, which is beneficial to the restoration of left atrial structure, ejection function, and hemodynamic function.

Texte intégral
Résumé :
Injection conformance reversion commonly observed during polymer flooding in offshore heterogeneous heavy-oil reservoirs weakens the volumetric sweep of polymer solution and compromises its EOR results. To investigate its mechanisms and impact factors, one mathematical model to predicate injection conformance behavior is constructed for heterogeneous reservoirs based on the Buckley-Leverett function. The different suction capability of each layer to polymer solution results in distinct change law of the flow resistance force, which in turn reacts upon the suction capability and creates dynamic redistribution of injection between layers. Conformance reversion takes place when the variation ratio of flow resistance force of different layers tends to be the same. The peak value and scope of conformance reversion decrease and reversion timing is advanced as oil viscosity or permeability contrast increases, or polymer concentration or relative thickness of low permeable layer decreases, which compromises the ability of polymer flooding to improve the volumetric sweep and lower suction of the low permeable layer. The features of offshore polymer flooding tend to make the injection conformance V-type and create low-efficiency circulation of polymer in a high permeable layer more easily. These results can provide guidance to improve the production performance of polymer flooding in offshore heterogeneous heavy-oil reservoirs.

Résumé :
A Coulomb oscillator with a variable normal force has been designed and manufactured to carry out a wide range of experimental dynamic analysis, especially the study of the non-reversibility of dry friction characteristics. The design choice was based on the criteria of accuracy of the mathematical model and flexibility in terms of parameter changes such as the natural frequency of the system, coefficient of friction and normal force. The system consists of a block mass attached to two coil springs and a dry frictional damper in which the friction force is varied by a pneumatic actuator. This allows a constant pressure between sliding surfaces to be maintained. The experimental set-up, the calibration procedure for the clamping device and typical results are presented. Experimental non-reversible dry friction characteristics are discussed.

Résumé :
Abstract OBJECTIVE Using the sequential inflation of 2 sphygmomanometers, Lewis et al. (Heart 16:1–32, 1931) concluded that compressive neuropathy was secondary to ischemia of the compressed nerve segment. Despite subsequent animal studies demonstrating that compressive lesions are more likely the result of mechanical nerve deformation, disagreement remains as to the etiology of rapidly reversible compressive neuropathy. Our hypothesis is that, during the classic sphygmomanometer experiments, the areas of nerve compression at the cuff margins overlapped, so that a region of transient nerve deformation persisted during the second cuff inflation. If true, the original results by Lewis et al. would be consistent with a mechanical pathogenesis. METHODS In our study, 6 patients underwent sequential upper extremity dual-sphygmomanometer inflation with serial assessment by grip-dynamometer and 2-point discrimination. The order of cuff inflation, as well as the distance between cuffs, was varied. Mean grip force and 2-point discrimination values were statistically compared between conditions. RESULTS Patients with overlapping cuffs maintained their neurological deficits, whereas those with separated cuffs experienced an improvement in both grip force (P = 0.02) and 2-point discrimination (P &lt; 0.001) when cuff inflation was switched. CONCLUSION Rapidly reversible compressive neuropathy seems to be secondary to mechanical nerve deformation at the margins of the compressive force rather than the result of ischemia of the compressed nerve segment. Overlap of the mechanically deformed nerve segments likely explains why neurological deficits persisted despite sequential cuff inflation in the classic experiments by Lewis et al.

Résumé :
The University of Arkansas (UA) blackberry breeding program began in 1964, with the aim to provide high-quality fruit to the fresh market industry. One of the important traits for successful blackberry (Rubus subgenus Rubus Watson) postharvest handling is flesh firmness, so developing cultivars with high firmness is a top priority for the fresh market blackberry breeding programs across the world. In particular, the Arkansas blackberry program has a wide range of genotypes with exceptional firmness characteristics, including fruit with a unique crispy texture and firmness. During 2013 and 2014, fruit firmness measurements were done on 15 Arkansas genotypes including those with crispy and noncrispy textures. Firmness measurements consisted of fruit compression, skin drupelet penetration, and receptacle penetration. Confocal photos were taken on sections of berries of a subset of crispy and noncrispy genotypes, and color reversion was evaluated among these genotypes after storage. Compression force values differentiated crispy and noncrispy genotypes, with average values of 11.8 Newton (N) and 8.0 N, respectively. Drupelet penetration force was also higher for crispy genotypes averaging 0.23 N and noncrispy 0.15 N; similarly, receptacle penetration force averaged 0.20 N for crispy and 0.18 N for noncrispy genotypes. Visual inspection of fruit tissue revealed that drupelet mesocarp cells and receptacle cells and cell walls of crispy genotypes maintained their structure during ripening and did not break apart, whereas noncrispy genotypes did not maintain their structure and cellular integrity. Color reversion is a postharvest disorder in which drupelets of blackberry fruits turn red after being black at harvest. Therefore, it has a negative impact for growers, shippers, and consumers. After storage at 5 °C for 7 days, crispy genotypes expressed low levels of reversion compared with noncrispy genotypes. For crispy genotypes, 13.2% of drupelets developed color reversion, whereas a 41.0% developed this disorder in noncrispy genotypes, implying a better postharvest potential of this texture.

A recovery/contracting force of 0.2 N with a work capacity of 0.175 kJ kg−1 was observed in crosslinked poly[ethylene-co-(vinyl acetate)] (cPEVA) fibers, which could enable the bending movement of the fingers by contraction upon heating. The reversible opening of the fingers was attributed to a combination of elastic recovery force of the origami structure and crystallization-induced elongation of the fibers upon cooling.

Résumé :
The force–extension behavior of individual mitotic newt chromosomes was studied, using micropipette surgery and manipulation, for elongations up to 80 times native length. After elongations up to five times, chromosomes return to their native length. In this regime chromosomes have linear elasticity, requiring ∼1 nN of force to be stretched to two times native length. After more than five times stretching, chromosomes are permanently elongated, with force hysteresis during relaxation. If a chromosome is repeatedly stretched to ∼10 times native length and relaxed, a series of hysteresis loops are obtained that converge to a single reversible elastic response. For further elongations, the linear dependence of force on extension terminates at a force “plateau” of ∼15–20 nN, near 30 times extension. After >30 times extensions, the elastic moduli of chromosomes can be reduced by more than 20-fold, and they appear as “ghosts”: swollen, elongated, and with reduced optical contrast under both phase and differential interference contrast imaging. Antibody labeling indicates that histone proteins are not being lost during even extreme extensions. Results are interpreted in terms of extension and failure of chromatin-tethering elements; the force data allow estimates of the number and size of such connectors in a chromosome.

SummaryCharacterization of a model of reversible foot lameness in the horse.Both forelimb hooves were fitted with a circumferential clamp. After three baseline measurements utilizing a force platform, one clamp was tightened to induce a grade 2.5/5 lameness and left in place for 120 hours. Serial heart rate and force platform measurements were obtained and the asymmetry index was calculated. After 120 hours, the clamp was released and force platform data recorded until the horse returned to soundness. The procedure was repeated for the opposite forelimb. The responses of treatment compared with the control for each outcome were analysed using linear mixed models. Time, limb (left or right), order of treatment, and interaction between time and order were used as fixed effects, whereas horse and limb were used as random effects.There was a significant increase in lameness associated with time and treatment order, where the second limb treated was more lame, based on the force platform data. The heart rate increased significantly with time and was significantly greater while the first limb was being treated. There was a significant effect of time on the increased subjective lameness score.The lameness was present throughout the measurement period, though the level of lameness lessened with time. The model may be applicable for evaluation of mechanisms to treat pain in the horse. The reason for the difference in treatment order needs to be identified.

Résumé :
This paper is aimed at the solution of the driving actuator of the reversing valve, which is the core component of CNC die forging hammer. The proposed electromagnetic drive method contributes to a precise control of the valve spool position and eliminates the transmission mechanism and hydraulic circuits. The complete structure and the topology structure of the electromagnetic part are designed to guarantee its high controllability and robustness. The structure parameters of the electromagnetic part are calculated based on the driving requirement of the reversing valve. With the finite element analysis of the direct driving part, saturation phenomenon of the magnetic circuit is eliminated and optimization of the output force ripple is performed. The output force of the electromagnetic part is simulated to reach 1000 N with a rated speed of 0.55 m/s, which satisfies the drive demand of the reversing valve spool and the ripple amplitude of the output force is reduced by 43.9%. The operational test of the electromagnetic direct drive component is conducted to verify the finite element method simulation method and shows an expected performance.

Résumé :
Variable rigidity materials that are safe, controllable, reversible, and repeatable have potentially widespread implications in robotic technologies. This paper presents a method for controlling the stiffness of materials for compliant tools, such as grippers, soft robots, and endoscopes. The force of electromagnetic suction transforms two structures from their relaxed-state into a more rigid state. The system presented here has the ability of quickly increasing the stiffness with increased current in the coils that create electromagnetic suction, wherein the stiffness can be controlled by the variation of supply current. The process of controlling stiffness variation is reversible and repeatable under the safe voltage of human body. The system can lead to the production of tools that are small, flexible, dexterous, and safe. Suction force, friction force, and rotational stiffness were calculated to evaluate the performance of the system. Experiments were carried out to verify the proposed concept and the calculations.

Résumé :
Registered nurses are currently threatened by a new managerial strategy to restructure work on hospital wards through the implementation of “Continuous Quality Improvement” and the “downsizing” of the professional work force. The strategy reintroduces nonprofessional and unlicensed nursing personnel in a manner that may displace large numbers of registered nurses (RNs) and affect patient care adversely. Ironically, not only is this change being implemented principally to reduce hospital costs rather than to improve quality, it reverses the cost-containment strategy implemented in the 1980s when hospitals displaced nonprofessional nursing workers and moved toward a professional work force. In this article, the author reviews the prior shift from “team nursing” with a stratified work force that included licensed practical nurses and nurses' aides to “primary nursing” and the trend toward all-RN staffing, and explains how this trend contributed to the present effort to reverse the process. The author then discusses current work redesign methods that have been adapted from traditional industrial applications to destroy work jurisdictions and further rationalize hospital production through the downsizing of the professional work force and the creation of cross-trained workers in a new team-based management approach. The article concludes by discussing nursing's response to corporate-imposed work restructuring and the significance of these changes.
