Effect of Anti-Price Gouging Law on Postdisaster Recovery Speed: Evidence from Reconstruction in Virginia and Maryland after Hurricane Sandy

The Association between Dietary Habits and Rapid Postoperative Recovery of Rotator Cuff Repair.

Some nutritional factors have been suggested to improve postoperative outcomes in rotator cuff (RC) repair, but dietary effects on the recovery speed after the surgery remain undefined. To investigate the potential roles of dietary habits in this context, we analyzed the 12-month follow-up data of 55 patients with RC repair and found that these patients could be categorized into a rapid recovery group (n = 35) and slow recovery group (n = 20) according to their postoperative recovery patterns. Group-based logistic analysis revealed that habitual intakes of meat (OR = 1.84, 95%CI, 1.22-2.76, p = 0.003), fruits (OR = 2.33, 95%CI, 1.26-5.67, p = 0.01), and wheat-flour foods (OR = 1.62, 95%CI, 1.2-2.25, p = 0.002) were significantly associated with rapid recovery. Moreover, among all intakes of wheat-flour foods, intakes of steamed and boiled flour products were also associated with rapid recovery. Further mediation analysis showed that eosinophilic granulocytes (EOs) significantly mediated the association between rapid RC recovery and the habitual intakes of meat (mediation proportion = 17.5%, P-mediation < 0.0001), fruits (17.9%, p < 0.0001), and wheat-flour foods (11.4%, p < 0.0001). Thus, our study suggests that certain dietary habits play beneficial roles in the context of postoperative recovery for RC repair.

Fabrication of shape memory polyimides with exploration of their activation mechanisms

The construction of polymer-based materials with reversible bidirectional shape memory effects, good thermal and electrically controlled properties is of paramount importance for the development of intelligent exploration in high-temperature fields. By adjusting the hydrogen bond contents of the structure to regulate the intermolecular strength, a series of random shape memory copolyimides have been synthesized with the triggering temperatures ranging from 275 to 384℃, which displayed good thermal stability, high shape fixation rate and shape recovery rate of over 95 % and 98 %, respectively, and excellent shape recovery speed (∼9 s). Visualized quantification of the microstructural phase evolution during stretching and the effects of hydrogen bonds on the properties of polyimide were deeply explored to better understanding the activation mechanisms of shape memory behaviors. Furthermore, flexible fabric composites with bidirectional shape memory effects motivated by electrical signals were also designed, providing a new sight of exploration for high-temperature shape-memory materials.

Quantifying Road Transport Resilience to Emergencies: Evidence from China

Facing the shock of emergencies, how resilient is the road transport system? In this process, how are the system’s absorption capacity, adaptability, and recovery capacity? These are very important for the development of sustainable road transportation. Taking China’s road transport during the COVID-19 pandemic as the research object, this paper introduces an integrated resilience quantification method, draws a road transport resilience curve, and comprehensively and dynamically analyzes and compares the resilience of China’s road transport system at different stages among different regions and under different epidemic waves. The results show that the resilience of road passenger and freight transport differs in the face of external disturbance. Freight transport resilience is better than that of passenger transport. Compared to passenger transport, freight transport is more robust; the impacted speed is slower, the recovery speed is faster, the recovery capacity is stronger, and the affected period is shorter. There is regional heterogeneity in road transport resilience. This heterogeneity is reflected in the whole change process of system performance with external disturbance, including absorption capacity, adaptation capacity, and recovery capacity. The resilience of road transport under different waves of the epidemic is different. Compared to the first wave of the epidemic, the resilience of road transport indicators at all stages has been dramatically improved in the later rebound wave of the epidemic. This can help in the development of evidence-based road transport sustainability strategies.

Application of laparoscopic backtracking full-thickness continuous everting suture for non-AOSC choledocholithiasis

BackgroundBased on the current trend of increasing incidence of choledocholithiasis, it is of great significance to explore the closure method of the common bile duct during laparoscopic choledocholithotomy.MethodsBacktracking full-thickness continuous everting suture was selected for primary closure of the common bile duct suture, while traditional T-tube drainage was selected for the control group. Propensity score matching (PSM) was used to reduce baseline differences between the two groups.ResultThe intraoperative blood loss, operation time, postoperative recovery speed, postoperative bleeding, postoperative pancreatitis, recurrence rate of bile duct stones, and hospitalization time in the primary closure group were all less than those in the T-tube drainage group.ConclusionUnder certain conditions, backtracking full-thickness continuous everting suture could benefit patients with choledocholithiasis compared with traditional T-tube drainage.

Population and housing recovery in Tōhoku, Japan

This paper examines the complexity of post-disaster reconstruction in the coastal Tōhoku region during the 10 years following the 2011 Great East Japan Earthquake (GEJE). Compared to official government accounts of rebuilding programs, which underscored their successful completion, many survivors felt that recovery had taken too long and that they did not see steady progress. This study contributes to the disaster recovery literature by underscoring the need for better tracking of reconstruction processes. I emphasize the importance of collecting and analyzing spatially disaggregated data sets of benchmarks and indicators, as well as searching for explanatory factors shaping the speed of recovery among the various communities affected by a catastrophic disaster. Conceptually, I develop a framework that identifies a number of different factors that account for spatial variation in disasters and their recovery. Empirically, I analyze population and housing data in Tōhoku fishing towns, indicating the role that the nature of the coastal terrain in particular locations played in shaping recovery. I also examine how the length of evacuation orders around the stricken Dai-ichi Nuclear Power Plant led to uncertain futures and the hesitation of residents to return to their home towns. The conclusion points to policy implications and suggestions for further research.

Relapse recovery in relapsing-remitting multiple sclerosis: An analysis of the CombiRx dataset.

Clinical relapses are the defining feature of relapsing forms of multiple sclerosis (MS), but relatively little is known about the time course of relapse recovery. The aim of this study was to investigate the time course of and patient factors associated with the speed and success of relapse recovery in people with relapsing-remitting MS (RRMS). Using data from CombiRx, a large RRMS trial (clinicaltrials.gov identifier NCT00211887), we measured the time to recovery from the first on-trial relapse. We used Kaplan-Meier survival analyses and Cox regression models to investigate the association of patient factors with the time to unconfirmed and confirmed relapse recovery. CombiRx included 1008 participants. We investigated 240 relapses. Median time to relapse recovery was 111 days. Most recovery events took place within 1 year of relapse onset: 202 of 240 (84%) individuals recovered during follow-up, 161 of 202 (80%) by 180 days, and 189 of 202 (94%) by 365 days. Relapse severity was the only factor associated with relapse recovery. Recovery from relapses takes place up to approximately 1 year after the event. Relapse severity, but no other patient factors, was associated with the speed of relapse recovery. Our findings inform clinical practice and trial design in RRMS.

Recovery of gait speed and timed up and go test in three weeks after total knee arthroplasty

Background Many previous studies reported that mobility did not recover to the preoperative level even several months after total knee arthroplasty (TKA). However, recent studies indicate that the time required for recovery may have been shortened. The correct information regarding the mobility improvement is very helpful in assessing a patients’ progress in rehabilitation. Therefore, we evaluated the mobility early after TKA. Materials and Methods One hundred seventy patients participated. We measured gait speed and the Timed Up and Go test (TUG) as mobility at pre-operatively and post-operatively at one, two, and three weeks. Results Gait speed at 1 and 2 weeks after TKA was significantly lower than the preoperative value, but no significant difference was observed at 3 weeks. TUG at 1 week after surgery was significantly slower than the preoperative value, but no difference at 2 weeks, and faster than the preoperative value at 3 weeks. Approximately half of the patients (gait speed, 50%; TUG, 55%) demonstrated improvements exceeding their preoperative values. Conclusions Our findings suggest that achieving preoperative mobility within 3 weeks after TKA may serve as a target for assessing early postoperative recovery progress.

Target Detection Method Based on Adaptive Step-Size SAMP Combining Off-Grid Correction for Coherent Frequency-Agile Radar

Coherent frequency-agile radar (FAR) has a low probability of intercept (LPI) and excellent performance of electronic counter-countermeasures (ECCM) and electromagnetic compatibility, which can improve radar cooperation and survivability in complex electromagnetic environments. However, due to the nonlinearity of radar carrier frequency and the limitation of the Doppler tolerance of high-resolution range cells, the undesirable blind-speed sidelobes are generated in the two-dimensional (2D) range–velocity plane after coherent integration (CI) using the traditional methods based on a matching filter, which may degrade the target detection performance. To solve this problem, an adaptive step-size sparsity adaptive matching pursuit (SAMP) algorithm combining off-grid correction (ASSAMP-OC) is proposed in this paper, which seeks to achieve a better trade-off between recovery efficiency and detection performance. Firstly, an adaptive iteration step size based on the Spearman correlation coefficients (SCCS) is devised, which solves the problem of the traditional SAMP algorithm being insensitive to the change in iteration step size when the residuals vary slightly, and improves the recovery speed. Secondly, the off-grid correction method by combining a regularized stagewise backtracking idea and gradient descent optimization (GDO) is adopted to improve the recovery accuracy and suppress the blind-speed sidelobe energy (BSSE), which helps to reduce CI gain loss and improve the target detection performance without the prior information of the sparsity lever. Finally, simulation and experimental results demonstrate the effectiveness and efficiency of the proposed method in terms of target detection probability, target signal energy ratio after recovery, and computational cost, compared to several existing methods.

The lip motion trajectory of eccentric oil seal considering material viscoelasticity

PurposeThis paper aims to study the motion trajectory of the oil seal for shaft in eccentric state and derive equation of lip motion trajectory.Design/methodology/approachThis paper analyzes the force during the motion of the eccentric lip by considering the material viscoelasticity, and a cam-plate mechanism is established as an equivalent model for the motion between the shaft and the lip; according to this, the equation of lip motion trajectory is derived.FindingsThe trajectory of the lip lags that of the shaft in the eccentric state because the viscoelasticity-affected lip recovery velocity is lower than the shaft recovery speed. The lip trajectory enters the lag phase earlier and the lag phase’s duration is longer with the increase of the eccentricity and rotational speed, because the deviation of the recovery velocities between the lip and the shaft will be exacerbated.Originality/valueInnovatively, by considering the viscoelasticity of the material, the cam-plate mechanism is used to equivalent the motion of the shaft-lip to derive the equation for the radial motion trajectory of the eccentric lip. The regularity of lip motion is the key to determining the performance of oil seals, and the eccentric lip trajectory research method revealed in this paper provides a research basis for the performance research and optimization of eccentric oil seals.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-06-2023-0161/

On the dynamics of order pipeline inventory in a nonlinear order-up-to system

Managing order pipeline inventory is important for controlling unwanted system dynamics, especially the bullwhip effect. We analytically explore the impact of desired target order pipeline inventory, advocated as a key decision in managing pipeline inventory, on system dynamics performance. Using control theory and system dynamics simulation, we evaluate two control mechanisms, termed as Reactive Pipeline Control (RPC) and Proactive Pipeline Control (PPC) approaches, in a nonlinear forbidden returns supply chain. We derive the analytical expressions of bullwhip under shock and seasonal demands and propose bullwhip avoidance strategies. The results indicate that an RPC based system always shows slower inventory convergence speed than that in the PPC based system, although the system with PPC policy may produce more unwanted oscillatory behaviour. Also, PPC always generates more bullwhip than that in an RPC-controlled system regardless of physical delays and system control parameters e.g. forecasting and inventory adjustment. Furthermore, compared with the linear system, the nonlinear forbidden returns system always generates less bullwhip and less oscillation at the expense of slow inventory recovery speed regardless of order pipeline control policies. Managers may consider different order pipeline control policies by jointly assessing their inherent system structure, control policies and customer demand characteristics, such as frequency and variance.

In-Memory Computing Circuit Implementation of Complex-Valued Hopfield Neural Network for Efficient Portrait Restoration

Complex-valued neural networks have better optimization capabilities, stronger robustness and richer characterization capabilities compared with real-valued neural networks, which has achieved good results in the field of portrait restoration. However, there is almost no circuit implementation of complex-valued neural networks. Based on this, this paper proposes an in-memory computing circuit implementation of complex-valued Hopfield neural network (CHNN) for the first time, which provides a highly accurate and efficient processing circuit for portrait restoration. Firstly, a new memristive array is proposed, which can realize parallel complex-valued multiplication and complex-valued vector-matrix multiplication. On the basis, a CHNN circuit that can perform large-scale recursive computations is designed. Due to the characteristics of in-memory computation, the computation speed and robustness have been improved when realizing portrait restoration. Different portrait restoration scenarios can be realized based on the programmability of the memristive array. Pspice simulation results show that the recovery speed of CHNN can reach the level of 0.1 ms, and the accuracy can reach above 97.00%. Robustness analysis shows that the circuit can tolerate a certain degree of programming error and has strong anti-noise performance.

Breathing New Life into an Old Tree: Resolving Logging Dilemma of B + -tree on Modern Computational Storage Drives

Having dominated databases and various data management systems for decades, B + -tree is infamously subject to a logging dilemma: One could improve B + -tree speed performance by equipping it with a larger log, which nevertheless will degrade its crash recovery speed. Such a logging dilemma is particularly prominent in the presence of modern workloads that involve intensive small writes. In this paper, we propose a novel solution, called per-page logging based B + -tree, which leverages the emerging computational storage drive (CSD) with built-in transparent compression to fundamentally resolve the logging dilemma. Our key idea is to divide the large single log into many small (e.g., 4KB), highly compressible per-page logs , each being statically bounded with a B + -tree page. All per-page logs together form a very large over-provisioned log space for B + -tree to improve its operational speed performance. Meanwhile, during crash recovery, B + -tree does not need to scan any per-page logs, leading to a recovery latency independent from the total log size. We have developed and open-sourced a fully functional prototype. Our evaluation results show that, under small-write intensive workloads, our design solution can improve B + -tree operational throughput by up to 625.6% and maintain a crash recovery time of as low as 19.2 ms, while incurring a minimal storage overhead of only 0.5-1.6%.

Effects of extracorporeal circulation with different time on platelet count after cardiac surgery: a retrospective study based on medical records

Our objective was to observe the effects of extracorporeal circulation (ECC) with different time on platelet count in patients undergoing cardiac surgery. A total of 427 patients who underwent elective cardiac surgery under ECC in affiliated hospital of north Sichuan medical college from January 1, 2018 to July 31, 2021 were divided into three groups according to ECC time. We concluded that thrombocytopenia was common after ECC, maximum drop of the platelet counts after ECC was usually seen on the second day after ECC, and platelet counts started to recover on the fifth day after ECC. With the extension of ECC time, the drop in platelet counts is more pronounced, the volume of perioperative blood loss and blood products transfusion are more, and the recovery level and speed of platelet counts is lower.

Laparoscopic Appendectomy Combined with an "Antimicrobial-Free" Strategy for Acute Uncomplicated Appendicitis.

Objective: To explore the efficacy and safety of enhanced recovery protocol (ERP) combined with laparoscopic appendectomy (LA) in the treatment of acute uncomplicated appendicitis (AUA) without antibiotics. Methods: In this study, a total of 160 patients with AUA who underwent LA between January 2018 and December 2021 were included and divided into the antibiotic group (n = 80) or the no-antibiotic group (n = 80). The patients in the antibiotic group received the ERP combined with antimicrobials during the perioperative period, while those in the no-antibiotic group only received the ERP during the perioperative period. The clinical data of these patients were collected to compare the inflammation level and stress state before and after surgery. In addition, the incidence of postoperative complications and the recovery speed of the patients were compared between groups. Results: There were no significant differences in the inflammation level and stress state before or after surgery, the incidence of postoperative complications or the recovery speed between the antibiotic group and the no-antibiotic group (P > .05). Conclusion: The use of ERP combined with LA as an antimicrobial-free treatment scheme in the perioperative period was found to be safe and effective for patients with AUA. Therefore, this approach is clinically valuable.

Determination of the effect of topical application of N-acetylcysteine on the recovery rate of patients with chronic rhinosinusitis after surgical treatment, based on SNOT-22 test scores

endonasal endoscopic sinus surgery ( FESS ) is the gold standard for the treatment of patients with chronic rhinosinusitis worldwide. The task of the otorhinolaryngologist is aimed at restoring the function of the osteomyetal complex . However, the tactics of the postoperative period, especially the topical form of treatment, remain an extremely important issue. The purpose of the study: Determination of the influence of the topical form of N-acetylcysteine on the speed of recovery of patients after FESS, compared to standardized topical treatment, based on the sino-nasal outcome test. The study was carried out at the Department of Otorhinolaryngology of Bogomolets National Medical University on the basis of the Oleksandriv Clinical Hospital of Kyiv together with the CNME "Kremenchuk City Hospital of Planned Treatment", Kremenchuk. A population of 96 patients aged 18 to 60 with a diagnosis of chronic rhinosinusitis after surgical treatment. The randomization method was two groups of patients were formed. 1st group (study) - 47 patients who received irrigation of the topical form of N-acetylcysteine. 2nd group (control) - 49 patients who received topical therapy using irrigation of 0.9% NaCl solution. The volume of surgical intervention of both groups of the study: Endonasal endoscopic maxillotomy, septoplasty , bilateral vasotomy of the lower nasal turbinates. To participate in the study, all participants had to sign an informed consent. All patients were surveyed using the SNOT22 test on the 1st day before surgery treatment and on the 3rd, 10th and 28th days after surgical treatment.According to the obtained results, the effectiveness of both methods of topical treatment was revealed (p=0.001). However, the use of topical N -acetylcysteine in patients of the study group has more effective dynamics of symptoms, according to the SNOT -22 questionnaire on the 3rd (p=0.034), 10th (p=0.002) and 28th day (p=0.001) after surgical treatment. Therefore, the topical form of N-acetylcysteine has an effective effect on the speed of recovery of the mucous membrane of the nasal cavity and paranasal sinuses and improves the quality of life in patients with chronic rhinosinusitis after FESS.

Psychological skills in athletic rehabilitation (AR): trainers and therapists perceptions

Sport-injury recovery is said to benefit from psychological abilities, yet there is little use of mental imaging in treatment protocols. To determine if the opinions of Physical Therapists (PTs) and Athletic Trainers (ATs) on the healing process for harmed sportsmen may be sped up by the use of positive language, setting targets, and mental imagery in treatment. To participate in an experiment that was only administered once and asked participants about the efficiency of psychological techniques, the ATs and PTs were approached for increasing adherence and speeding up the healing of wounded sportsmen enduring treatment. A total number of 309 ATs and 356 PTs responded out of the one thousand ATs and PTs that were randomly selected. The Attitudes about Imagery (AAI) study gauges opinions on psychological techniques for improving injured athletes' commitment and recovery speed. The AAI asks questions on demographics and measures attitudes regarding the influence of pain management on injured athletes' compliance with therapy and utilizes fifteen inquiries and a Likert scale with seven points to measure recovery speed. To ascertain if variations in views occurred due to the professionals' educational background, training experience, and interest, we performed 1-way analyses of variances. The usefulness of psychological skills to support the recovery process was generally viewed favourably by ATs and PTs. The utilization of mental abilities is considered in terms of clinical ramifications.
