Hydrodynamic Characteristics of Bridge Cofferdam Under Multidirectional Focused Waves
Authors: Wang X. , Qu K. 
Published: January 2024

Abstract
In the process of coastal bridge construction, cofferdams become necessary facilities to ensure the construction environment is dry and safe. However, during the construction period of coastal bridges, extreme surges and waves caused by typhoons can impose huge hydrodynamic loads on the cofferdam and a potential threat to the safety and integrity of the cofferdam. Therefore, it becomes valuable to assess the hydrodynamic loads of bridge cofferdam under extreme waves. Meanwhile, in the harsh marine environment, waves tend to propagate in multiple directions. However, previous studies mainly focused on the hydrodynamic characteristics of cofferdam by waves that propagate in one direction. Few studies were carried out on the hydrodynamic characteristics of cofferdam under the action of extreme waves in multiple directions. To fill in the gaps in previous research, this study numerically studied the complex wave hydrodynamics of cofferdam under multidirectional extreme waves. Effects of several major factors, i.e., significant wave height, peak wave period, water depth, spreading angle, incident wave angle, and submergence depth were systematically analyzed. It is desired that present research could enhance our understanding of the complex wave hydrodynamics of bridge cofferdam under multidirectional focused waves.

Published: January 2024

Abstract
Compared to rigid materials, people have a distinct tactile perception when touching flexible materials. Moreover, adding micro-patterns to the surface enhances the tactile experience even further. This sensation arises from the physical stimulation of frictional behavior between the skin and flexible materials. Therefore, this study focuses on human fingers as the research subjects and employs flexible materials with micro-textured surfaces as frictional objects. A friction test setup is designed to conduct a series of finger friction experiments, and theoretical explanations are provided to elucidate the reasons for performance variations. Research findings show that as the normal load increases, the frictional force gradually increases while the friction coefficient decreases. The former is attributed to the expanding contact area, while the latter is due to the inconsistent rate of frictional force increment with the normal load. The impact of friction velocity is mainly caused by changes in the viscous forces generated at the liquid film in the contact interface and the energy loss in elastic hysteresis. On the other hand, the effect of surface micro-topography is primarily a result of the transition between partial contact and full contact modes under the influence of normal load, leading to alterations in the contact area. Overall, during the finger friction process on a flexible micro-textured surface, changes in contact area play a vital role in modifying frictional performance, with adhesive friction exerting a more significant influence than deformation friction. This study summarizes the variations in frictional performance parameters based on experiments and analyzes the effects of contact area changes and deformation friction mechanisms from a theoretical perspective, providing a theoretical foundation for exploring the genesis of delicate tactile sensations during friction.
A Fast Calculation Approach for Elastohydrodynamic Finite Line Contacts Applicable to Online Calculations of Rolling Bearing Models
Authors: Yang Di , Wang Xi , Hou Yu 
Published: January 2024

Abstract
Finite line contacts in rolling element bearings are usually under the regime of elastohydrodynamic lubrication (EHL). To obtain deeper insights into bearing performance, it is necessary to directly couple EHL contact models into bearing models. However, the existing EHL contact models are either too time consuming to be employed in the bearing model or too simplified to consider tilting contact behaviors and actual roller profiles. A fast calculation approach for EHL finite line contacts is proposed by combining the empirical film thickness formulas that have been developed for decades and an improved slicing technique that considers the coupling behaviors between slices. The proposed approach can not only predict the contact stiffness (normal contact stiffness and tilting contact stiffness) and contact states (contact pressure and film thickness) accurately but also is universal for different profiled contacts and material properties. The proposed approach costs only a few milliseconds for a single load case, which enables it to be directly employed in bearing models. Besides, the proposed approach is more of a framework, the use of which can be extended by involving different film thickness formulas and correction factors to consider complicated EHL behaviors such as thermal effects, shear thinning effects, surface roughness, lubricant starvation, and so on.

Published: January 2024

Abstract
Nickel–phosphorus/black phosphorus (Ni–P/BP) coatings were deposited on ordinary carbon structural steel (Q235 steel) by electroless plating. The tribological behavior of the Ni–P/BP coatings and traditional nickel–phosphorus (Ni–P) coating was studied comparatively on a reciprocating tribometer. The Ni–P/BP coatings exhibited good tribological performances in the water environment. Compared with traditional Ni–P coating, the friction coefficient of Ni–P/BP20 coating in deionized water and Ni–P/BP30 coating in 3.5 wt% sodium chloride decreased by 31% and 30% at 4 N, respectively. The major wear mechanism of Ni–P/BP coatings was ascribed to slight abrasive wear. This was mainly due to the combination of the higher hardness of coatings, the interlayer slip of adsorbed black phosphorus nanosheets, and the development of oxide tribofilm at the sliding interfaces.

Authors: Xie Jinfeng , Yang Congbin , Ma Honglie , Li Ying , Liu Zhifeng , Yan Jun 
Published: January 2024

AbstractThe internal feedback hydrostatic rotary table is a precision support device, and its performance relies heavily on the oil pad. However, uncertainties in the manufacturing process are often overlooked during the stiffness optimization, affecting the reliability of the optimized results. Accordingly, this paper aims to analyze the influence of structural parameters on the stiffness performance of the internal feedback hydrostatic rotary table and to perform reliability optimization considering the uncertainties. Initially, a theoretical computational model of internal feedback hydrostatic rotary table, accounting for the oil leakage effect, is proposed. The model's accuracy is validated through comparative simulation calculations, and based on this model, the load-bearing performance of the table is further analyzed. Subsequently, focusing on the structural characteristics of the oil pad, a reliability optimization model that considers manufacturing uncertainties is proposed. To improve the optimization efficiency, a Levenberg–Marquardt Backpropagation (LM-BP) neural network is introduced as a surrogate model for theoretical calculations. The oil pad is optimized through a particle swarm optimization algorithm. Ultimately, the optimal structural size parameters of the oil pad are obtained, achieving maximal stiffness under a high level of reliability. Both the stiffness performance and the reliability level of the rotary table are substantially enhanced. The results indicate that the proposed method can significantly improve performance and reliability in practical applications.

Purpose: To examine the effects of 4 programming models (linear [LP], undulating [UP], reverse [RP], and constant [CP]) on physical performance. Methods: Forty-eight moderately strength-trained men were randomly assigned to LP, UP, RP, and CP groups according to their 1-repetition maximum (1RM) in the full-squat exercise (SQ) and followed an 8-week training intervention using the SQ and monitoring movement velocity for every repetition. All groups trained with similar mean relative intensity (65% 1RM), number of repetitions (240), sets (3), and interset recovery (4 min) throughout the training program. Pretraining and posttraining measurements included, in the SQ, 1RM load, the average velocity attained for all absolute loads common to pretests and posttests (AV), and the average velocity for loads that were moved faster (AV > 1) and slower (AV < 1) than 1 m·s−1 at pretraining tests. Moreover, countermovement jump height and 20-m running sprint time were measured. Results: A significant time effect was found for all variables analyzed (P < .05), except for 20-m running sprint time. Significant group × time interactions were observed for 1RM, AV > 1, and AV (P < .05). After training, all groups attained significant strength gains on 1RM, AV, AV > 1, and AV < 1 (P < .001–.01). LP and RP groups improved their countermovement jump height (P < .01), but no significant changes were observed for UP and CP. No significant improvements were achieved in 20-m running sprint time for any groups. Conclusions: These different programming models are all suitable for improving physical performance. LP and RP induce similar or greater gains in physical performance than UP and CP.

Authors: Habeeb Christine M. , Stephen Sarah A. , Eklund Robert C. 
Published: January 2024

Efficacy beliefs targeting personal (self-efficacy), teammates’ (other-efficacy), and conjoint (collective efficacy) abilities are each associated with performance of athlete pairs. The purpose of this study was to examine (a) congruence/incongruence of efficacy beliefs between athletes in a pair as a predictor of quality of individual and team performance and (b) quality of performance relative to efficacy congruence at high, moderate, and low levels of efficacy. Eighty-two cheerleading pairs, composed of one base and one flyer, completed questionnaires assessing self-, other, and collective efficacy prior to a national collegiate competition. Individual and team performances were assessed using objective criteria. Polynomial regression analyses indicated that team performance was predicted by congruence of (a) both athletes’ collective efficacy beliefs and (b) base self-efficacy and flyer other efficacy. Findings supported that congruence at moderate to high levels of efficacy was associated with better performance relative to incongruent efficacy beliefs across the two athletes.

Results: A total of 65 patients (72.3% females), with a mean age of 41.8 years, were analyzed. At the end of 6 weeks, the results showed clinically and statistically significant differences (P < .05). At 1-year follow-up, the differences were: Patient-Rated Tennis Elbow Evaluation −31 points (P < .001); grip strength +33.6% (P < .001); Disabilities of the Arm, Shoulder, and Hand −34.2 points (P < .001); Visual Analogue Scale at rest −2.5 cm (P < .001); and Visual Analogue Scale at grip −2.3 cm (P < .001). Conclusion: At the end of 6 weeks and at 1-year follow-up, conventional treatment plus scapular exercises program showed statistically and clinically significant differences in all functional outcomes assessed in patients with lateral elbow tendinopathy.
Soft-controlled quantum gate with enhanced robustness and undegraded dynamics in Rydberg atoms
Authors: Wu Qiaolin , Xing Jun , Yin Hongda 
Published: January 2024

AbstractRydberg atoms have exhibited excellent potentials to become a competent platform of implementing quantum computation, which demands to execute various quantum gates fast and faithfully. We propose a dynamic mechanism of two interacting Rydberg atoms for implementing a high-fidelity SWAP gate on ground-state manifolds, where the amplitude modulation and soft quantum control of lasers driving ground-Rydberg state transitions are elaborately matched with the interaction strength between atoms so as to engineer the desired transformation of atomic states. Compared with the recent Rydberg-atom SWAP gate scheme, the present one possesses the undegraded first-order dynamics and shows an interference-induced suppression of the doubly-excited Rydberg state, so it costs shorter gate time and exhibits greater robustness against atomic decay and deviations in the interatomic separation (interaction strengths). The present mechanism of implementing a SWAP gate on interacting Rydberg atoms could facilitate high-fidelity demonstrations of atomic ground state transformation and further exploitation of peculiar dynamics.

Abstract

The p53 family member TP63 encodes two sets of N-terminal isoforms, TAp63 and ΔNp63 isoforms. They each regulate diverse biological functions in epidermal morphogenesis and in cancer. In the skin, where their activities have been extensively characterized, TAp63 prevents premature aging by regulating the quiescence and genomic stability of stem cells required for wound healing and hair regeneration, while ΔNp63 controls maintenance and terminal differentiation of epidermal basal cells. This functional diversity is surprising given that these isoforms share a high degree of similarity, including an identical sequence for a DNA-binding domain. To understand the mechanisms of the transcriptional programs regulated by each p63 isoform and leading to diverse biological functions, we performed genome-wide analyses using p63 isoform-specific chromatin immunoprecipitation, RNA sequencing, and metabolomics of TAp63−/− and ΔNp63−/− mouse epidermal cells. Our data indicate that TAp63 and ΔNp63 physically and functionally interact with distinct transcription factors for the downstream regulation of their target genes, thus ultimately leading to the regulation of unique transcriptional programs and biological processes. Our findings unveil novel transcriptomes regulated by the p63 isoforms to control diverse biological functions, including the cooperation between TAp63 and NRF2 in the modulation of metabolic pathways and response to oxidative stress providing a mechanistic explanation for the TAp63 knock out phenotypes.

Significance:
The p63 isoforms, TAp63 and ΔNp63, control epithelial morphogenesis and tumorigenesis through the interaction with distinct transcription factors and the subsequent regulation of unique transcriptional programs.

BACKGROUND:
To evaluate whether cancer modifies the effect of intensive blood pressure control on major cardiovascular outcomes.

METHODS:
Using data of the SPRINT (Systolic Blood Pressure Intervention Trial), we compared the risk of the composite outcomes of myocardial infarction, other acute coronary syndromes, stroke, heart failure, and cardiovascular death in patients with and without a history of cancer. Using Cox proportional hazards regression, we tested interactions between history of cancer and intensive blood pressure control on major cardiovascular outcomes.

RESULTS:

The study included a total of 9336 patients, with a mean age of 67.9±9.4 years, among whom 2066 (22.2%) were cancer survivors. Over a median follow-up of 3.2 years, 561 primary cardiovascular outcomes were observed. Cancer survivors had a similar risk of experiencing the primary outcome compared with patients without cancer after multivariable adjustment (adjusted hazard ratio, 0.94 [95% CI, 0.77–1.15]). Intensive blood pressure control reduced risk of the primary cardiovascular outcome similarly for cancer survivors (hazard ratio, 0.70 [95% CI, 0.51–0.97]) and patients without cancer (HR, 0.76 [95% CI, 0.63–0.93];
P
for interaction 0.74).

CONCLUSIONS:
In SPRINT study, intensive blood pressure treatment reduced the risk of major cardiovascular events in cancer survivors to a similar extent to that of patients without cancer. Cancer history not requiring active treatment in last 2 years should not be an obstacle to intensive treatment of hypertension. This post hoc analysis should be considered as hypothesis-generating and merit further clinical trial.

Associative Visuomotor Learning Using Transcranial Magnetic Stimulation Induces Stimulus–Response Interference

Published: January 2024

Abstract
Classical conditioning states that the systematic co-occurrence of a neutral stimulus with an unconditioned stimulus can cause the neutral stimulus to, over time, evoke the same response as the unconditioned stimulus. On a neural level, Hebbian learning suggests that this type of learning occurs through changes in synaptic plasticity when two neurons are simultaneously active, resulting in increased connectivity between them. Inspired by associative learning theories, we here investigated whether the mere co-activation of visual stimuli and stimulation of the primary motor cortex using TMS would result in stimulus–response associations that can impact future behavior. During a learning phase, we repeatedly paired the presentation of a specific color (but not other colors) with a TMS pulse over the motor cortex. Next, participants performed a two-alternative forced-choice task where they had to categorize simple shapes and we studied whether the shapes' task-irrelevant color (and its potentially associated involuntary motor activity) affected the required motor response. Participants showed more errors on incongruent trials for stimuli that were previously paired with high intensity TMS pulses, but only when tested on the same day. Using a drift diffusion model for conflict tasks, we further demonstrate that this interference occurred early, and gradually increased as a function of associated TMS intensity. Taken together, our findings show that the human brain can learn stimulus–response associations using externally induced motor cortex stimulation. Although we were inspired by the Hebbian learning literature, future studies should investigate whether Hebbian or other learning processes were also what brought about this effect.
The Early Subcortical Response at the Fundamental Frequency of Speech Is Temporally Separated from Later Cortical Contributions

Published: January 2024

Abstract
Most parts of speech are voiced, exhibiting a degree of periodicity with a fundamental frequency and many higher harmonics. Some neural populations respond to this temporal fine structure, in particular at the fundamental frequency. This frequency-following response to speech consists of both subcortical and cortical contributions and can be measured through EEG as well as through magnetoencephalography (MEG), although both differ in the aspects of neural activity that they capture: EEG is sensitive to both radial and tangential sources as well as to deep sources, whereas MEG is more restrained to the measurement of tangential and superficial neural activity. EEG responses to continuous speech have shown an early subcortical contribution, at a latency of around 9 msec, in agreement with MEG measurements in response to short speech tokens, whereas MEG responses to continuous speech have not yet revealed such an early component. Here, we analyze MEG responses to long segments of continuous speech. We find an early subcortical response at latencies of 4–11 msec, followed by later right-lateralized cortical activities at delays of 20–58 msec as well as potential subcortical activities. Our results show that the early subcortical component of the FFR to continuous speech can be measured from MEG in populations of participants and that its latency agrees with that measured with EEG. They furthermore show that the early subcortical component is temporally well separated from later cortical contributions, enabling an independent assessment of both components toward further aspects of speech processing.
