Effect of Aging and Cooling Path on the Super β-Transus Heat-Treated Ti-6Al-4V Alloy Produced via Electron Beam Melting (EBM)

This work focuses on the effect of different heat treatments on the Ti-6Al-4V alloy processed by means of electron beam melting (EBM). Super β-transus annealing was conducted at 1050 °C for 1 h on Ti-6Al-4V samples, considering two different cooling paths (furnace cooling and water quenching). This heat treatment induces microstructural recrystallization, thus reducing the anisotropy generated by the EBM process (columnar prior-β grains). Subsequently, the annealed furnace-cooled and water-quenched samples were aged at 540 °C for 4 h. The results showed the influence of the aging treatment on the microstructure and the mechanical properties of the annealed EBM-produced Ti-6Al-4V. A comparison with the traditional processed heat-treated material was also conducted. In the furnace-cooled specimens consisting of lamellar α+β, the aging treatment improved ductility and strength by inducing microstructural thickening of the α laths and reducing the β fraction. The effect of the aging treatment was also more marked in the water-quenched samples, characterized by high tensile strengths but limited ductility due to the presence of martensite. In fact, the aging treatment was effective in the recovery of the ductility loss, maintaining high tensile strength properties due to the variation in the relative number of α/α’ interfaces resulting from α’ decomposition. This study, therefore, offers an in-depth investigation of the potential beneficial effects of the aging treatment on the microstructure and mechanical properties of the EBM-processed super β-transus heat-treated Ti-6Al-4V alloy under different cooling conditions.
Radiographic and Histomorphometric Evaluation of Sinus Floor Augmentation Using Biomimetic Octacalcium Phosphate Alloplasts: A Prospective Pilot Study

This prospective single-arm clinical study aimed to radiographically and histomorphometrically evaluate the efficacy of the lateral approach for sinus floor elevation (LSFE) using biomimetic octacalcium phosphate (OCP) synthetic bone graft (Bontree®). LSFE using Bontree® was performed on 10 patients (15 implant placement sites) willing to undergo implant surgery, followed by implant placements after 6 months of the healing period. The vertical bone height (VBH) and Hounsfield unit (HU) values at each implant placement site were evaluated radiographically using cone-beam computed tomography at baseline immediately after surgery (T1) and 6 months after surgery (T2). A histomorphometric evaluation of the bone core biopsy specimen was also performed. The mean VBH and HU changes at all sites included a decrease by 0.91 mm and a statistically significant increase by 431.86, respectively, from T1 to T2. The mean ratio of the newly formed bone (23.34% ± 10.63%) was greater than that of the residual bone graft (19.09% ± 8.74%), indicating that Bontree® is effective for new bone formation. This pilot study suggests that Bontree® is a promising bone substitute for LSFE.
Frequency support from PMSG-based wind turbines with reduced DC-link voltage fluctuations

Frequency droop control is widely used in permanent magnet synchronous generators (PMSGs) based wind turbines (WTs) for grid frequency support. However, under frequency deviations, significant DC-link voltage fluctuations may occur during the transient process due to sudden changes in real power of such WTs. To address this issue, a current feedforward control strategy is proposed for PMSG-based WTs to reduce DC-link voltage fluctuations when the WTs are providing frequency support under grid frequency deviations. Meanwhile, the desired frequency support capability of the PMSG-based WTs can be ensured. Simulation results verify the rationality of the analysis and the effectiveness of the proposed control method.
Construction and validation of an early prediction model of delirium in children after congenital heart surgery

Background Delirium often occurs in children with congenital heart disease in the early postoperative period, which is not conducive to the rehabilitation and prognosis. There is little evidence to prove the effectiveness and safety of drug treatment of delirium in children, and the prevention has become an important topic. The purpose of this study is to analyze the early risk factors of delirium in children after congenital heart surgery, establish a nomogram prediction model, and explore the application efficiency of the model, so as to provide reference for early prevention of delirium. Methods A total of 362 children treated in the cardiac intensive care unit (CICU) of Shanghai Children’s Medical Center after congenital heart surgery from February 15 to April 15, 2021 were enrolled for the construction of the model. Bedside nurses who received unified training used the Cornell Assessment of Pediatric Delirium (CAPD) to evaluate delirium and recorded sixteen preoperative- and intraoperative-related influencing factors. A nomogram prediction model was created using multivariate logistic regression. The prediction effect of the model was evaluated by C-index and Brier value, and 96 children from April 16 to May 15, 2021 were included for effect verification. The model’s effectiveness was validated by comparing the occurrence of delirium in children predicted by the model with the actual occurrence. Results Multivariate logistic regression analysis showed that male gender [odds ratio (OR) =1.786, 95% confidence interval (CI): 1.018–3.134, P=0.043], age <6.5 months (OR =0.224, 95% CI: 0.126–0.399, P=0.000), disease severity ≥4 points (OR =6.955, 95% CI: 3.564–13.576, P=0.003), and operation time ≥148 min (OR =2.401, 95%CI: 1.336–4.315, P=0.000) were independent risk factors for delirium in children after cardiac surgery. The C-index of the nomogram prediction model was 0.808, sensitivity was 76.1%, specificity was 70%, and the Brier value was 0.142. The validation of the model showed that the model predicted 20 cases and the actual occurrence was 20 cases, of which 8 cases were false negative and 8 cases were false positive, and the sensitivity, specificity, and accuracy of the model were 60%, 89.5%, and 83.3%, respectively. Conclusions The prediction model constructed in this study could provide early prediction of the occurrence of delirium in children after congenital heart surgery to a certain extent.
The moderating effects of corporate and national factors on lean projects barriers: a cross‐national study

Abstract Despite companies’ efforts to develop lean thinking in their industrial context, the implementation of many lean projects has not been consistently successful, often resulting in delay, failure, abandonment or rejection. Whereas some authors emphasised that company characteristics, like the product demand profile, are significant factors in lean projects, other studies analysed the impact of national culture. This paper aims to study the combined effect of various factors related to national culture and company characteristics of lean implementation barriers in order to determine whether the environmental context in which the company operation can affect the outcome of lean project implementation. A survey has been conducted to collect information about companies of various sizes (small–medium–large) in all industry fields. Data from companies, including manufacturing firms, in 23 different countries, were analysed in depth by a combination of Association Rules and Network Analysis. The results show that some national culture dimensions, such as Performance Orientation and Gender Egalitarianism, influence lean management success and help to maintain a lean culture. Maintaining a lean culture is even more critical than developing it. Furthermore, if the implementation of lean practices is an arduous task for large organisations, it becomes even greater for SMEs. Other cultural factors of individuals such as Uncertainty Avoidance, Future Orientation and Institutional Collectivism also help to support a lean culture and overcome human and cultural barriers.
The Impact of Parent–Child Attachment on School Adjustment in Left-behind Children Due to Transnational Parenting: The Mediating Role of Peer Relationships

In China’s eastern coastal areas, the transnational parenting of left-behind children creates a distinct form of left-behind child. Previous research has indicated that children who have been left behind have a low degree of school adjustment. The major purpose of this research was to investigate the impact of parent–child attachment on school adjustment in children left behind by migrant parents, as well as the mediating role of peer relationships in this process. The parent–child attachment section of the Inventory of Parent and Peer Attachment (IPPA), the Adaptation subscale of the Adolescent Mental Health Quality Questionnaire—Chinese Version (AMHQQ-C), and the Student Peer Relationship Scale (SPRC) were used to survey 405 left-behind children in grades 3–6 of seven elementary schools in the hometowns of overseas Chinese parents from Zhejiang Province. It was discovered that, compared to non-left-behind children, left-behind children showed lower levels of parent–child attachment and school adjustment, while peer relationships appeared polarized. In addition, parent–child attachment and peer relationships considerably predicted the level of school adjustment in children left behind due to transnational parenting. More importantly, the mediation analysis revealed a partial mediating effect of peer relationships on the linkages between parent–child attachment and school adjustment among children who were left behind in transnational foster care.
Design, simulation and experiment of PSO-FOPID controller for height position control of a scissor mechanism platform

This paper proposes the PSO-FOPID controller, which is a Fractional Order Proportional-Integral-Derivative (FOPID) controller tuned using particle swarm optimization with spreading factor algorithm for height position control of a scissor mechanism platform. The tuning process of five control gains in the FOPID controller is technically challenging to achieve high position accuracy. In this study, this problem is addressed through the offline tuning method by using particle swarm optimization with the spreading factor algorithm to reduce the complexity in tuning the control gains. From the experimental study, it is found that the proposed controller can eliminate the steady-state error under the two input references with approximately 1.5% and 0.9% reductions of the overshoot and undershoot in the height position response as compared to its promising performances in simulations. It is envisaged that the PSOFOPID controller can be useful in designing effective height position control of a non-linear platform.
“Nothing for Us Without Us”: An Evaluation of Patient Engagement in an HIV Care Improvement Collaborative in the Caribbean

This evaluation suggests that it is both possible and valuable to include patients as partners in quality improvement efforts, especially when resources must be prioritized for the highest impact efforts. Patient engagement in the improvement process is particularly powerful when addressing illnesses that may be stigmatized such as HIV. Key Findings Intentionally building pathways for patient partnership in the improvement collaborative resulted in increased integration of and appreciation for patient perspectives. The conditions created in the Caribbean Regional Quality Improvement Collaborative resulted in increased mutual understanding and empathy between health care providers and people living with HIV, both of whom believed it benefited the quality improvement work. Key Implications In addressing the challenges of improving quality of care and improving health outcomes in lower-resource countries, policy makers should leverage quality improvement initiatives to integrate patients and those who work in the system to identify impactful changes. Program managers should intentionally design for authentic engagement with patients in improvement initiatives including creating optimal conditions of intergroup contact theory: equal group status within the intergroup setting, common goals, cooperation towards goals, and institutional support. ABSTRACT Introduction: Patient engagement is increasingly recognized as a key strategy to promote patient-centered care and accelerate health care improvements. Ensuring patient participation in improvement efforts is particularly important with stigmatized illnesses and marginalized populations. Despite the attention it has garnered, patient engagement is still not widely implemented and has not been well documented in global health literature. Methods: We implemented a patient-engagement strategy to involve people living with HIV in quality improvement efforts. As part of the Caribbean Regional Quality Improvement Collaborative, quality improvement teams from Barbados (1 team), Jamaica (20 teams), Suriname (3 teams), and Trinidad and Tobago (2 teams) engaged health care providers from care facilities and people living with HIV to serve as community representatives (CRs) to lead the improvement efforts alongside them. This strategy was evaluated via a mixed method design that included 2 rounds of semistructured, in-depth interviews with patients and providers. Results: Findings suggest that the patient engagement strategy had several key strengths: it promoted the collection, use, and appreciation of patient input to inform health care improvements at the facility level; facilitated the empowerment of CRs; enhanced mutual understanding and empathy between CRs and providers; and helped to dispel HIV stigma and discrimination in health care settings. Moreover, both health care providers and CRs reported that CR opinions and perspectives are as important as providers' and that CR participation in the improvement process was beneficial.
in Nearly Normal Galaxies

A thread rolling machine is disclosed wherein a continuously adjustable timing screw is used to adjust the phase of the feed of a workpiece relative to the instantaneous position of a rotary die cooperating with a stationary die. This timing substantially eliminates any mismatch of thread rolling by the two dies. The rotatable timing screw adjusts the peripheral position of a cam follower relative to a feed cam by moving the fulcrum point of a bell crank lever on which the cam follower is carried. Rotation of the timing screw adjusts the peripheral position of the cam follower relative to the feed cam. The above description is merely one form of the invention and is not to be construed as limiting on the scope of the invention.

Then future trends are predicted.
Water Uptake and Hormone Modulation Responses to Nitrogen Supply in Populus simonii under PEG-Induced Drought Stress

In the present study, the effects of nitrogen (N) supply on water uptake, drought resistance, and hormone regulation were investigated in Populus simonii seedlings grown in hydroponic solution with 5% polyethylene glycol (PEG)-induced drought stress. While acclimating to drought, the P. simonii seedlings exhibited a reduction in growth; differential expression levels of aquaporins (AQPs); activation of auxin (IAA) and abscisic acid (ABA) signaling pathways; a decrease in the net photosynthetic rate and transpiration rate; and an increase in stable nitrogen isotope composition (δ15N), total soluble substances, and intrinsic water use efficiency (WUEi), with a shift in the homeostasis of reactive oxygen species (ROS) production and scavenging. A low N supply (0.01 mM NH4NO3) or sufficient N supply (1 mM NH4NO3) exhibited distinct morphological, physiological, and transcriptional responses during acclimation to drought, primarily due to strong responses in the transcriptional regulation of genes encoding AQPs; higher soluble phenolics, total N concentrations, and ROS scavenging; and lower transpiration rates, IAA content, ABA content, and ROS accumulation with a sufficient N supply. P. simonii can differentially manage water uptake and hormone modulation in response to drought stress under deficient and sufficient N conditions. These results suggested that increased N may contribute to drought tolerance by decreasing the transpiration rate and O2− production while increasing water uptake and antioxidant enzyme activity.
Genetics and Epigenetics of Spontaneous Intracerebral Hemorrhage

Intracerebral hemorrhage (ICH) is a complex and heterogeneous disease, and there is no effective treatment. Spontaneous ICH represents the final manifestation of different types of cerebral small vessel disease, usually categorized as: lobar (mostly related to cerebral amyloid angiopathy) and nonlobar (hypertension-related vasculopathy) ICH. Accurate phenotyping aims to reflect these biological differences in the underlying mechanisms and has been demonstrated to be crucial to the success of genetic studies in this field. This review summarizes how current knowledge on genetics and epigenetics of this devastating stroke subtype are contributing to improve the understanding of ICH pathophysiology and their potential role in developing therapeutic strategies.
Prospective multicenter study of the efficacy and safety of cold forceps polypectomy for ≤ 6-mm non-ampullary duodenal low-grade adenomas

Background and study aims Because the endoscopic treatment for non-ampullary duodenal adenoma (NADA) has a non-negligible risk of adverse events (AEs), a safe and easy treatment for NADA is desirable. This was a multicenter prospective trial evaluating the efficacy and safety of cold forceps polypectomy (CFP) for diminutive NADAs. Patients and methods This study was prospectively conducted at six general hospitals and one university hospital. The inclusion criteria were histologic and endoscopic diagnosis of low-grade NADA measuring ≤ 6 mm. A second endoscopy was scheduled for 1 month after CFP. After confirmation of the success of CFP, 6-month and 12-month surveillance endoscopies were scheduled. The primary endpoint was the endoscopic and histologic disease disappearance rates at the 12-month endoscopy. Results Thirty-nine lesions from 38 patients were prospectively included. Median tumor size at enrollment was 5 mm (range 3–6 mm). There were four cases of remnant lesions at the second endoscopy, and the lesion disappearance rate of single CFP was 89.7 % (35 /39; 95 % confidence interval (CI), 76.9 %–97.9 %). In three cases, complete removal of the lesion was achieved with a single re-CFP, but one case required four repeat CFPs. The lesion disappearance rate at 12-month endoscopy was 97.4 % (38 /39; 95 %CI, 86.8 %–99.5 %). During the follow-up period, no AEs related to CFP were observed. Conclusions CFP for NADA ≤ 6 mm was safe and effective in this study. This common endoscopic method to remove lesions may be an option for treatment of diminutive NADAs.
Conditions and Causes of Split Ad Effectiveness

Split advertising technique involves two distinct and separate components that must be jointly experienced to receive the entirety of a message. An example is a Nike ad that began on TV and then was completed at a web site. This mode of presentation is termed the “split advertising technique” or simply, the “split ad technique” as well as Hybrid style of advertising. The objective of this investigation is to explore the effectiveness of the split ad technique. Experiment 1 provides evidence that split ads can increase attitudes of light users. This increase seems due to the importance attached to the information contained in the second part of the split ad. In experimentation two, in addition to replicating results from Experiment 1, a more complex pattern of responses is discovered when timing of measurement is considered. For measurements taken immediately after exposure to the advertising materials, enhanced attitudes and attribute importance were again manifest for light users exposed to a split ad, and undermined attitudes were observed for heavy users. However, for measures taken after a week’s delay, the positive influence on light users did not persist. The negative impact on heavy users, however, was enduring. Results of two experiments indicate that a split ad can focus attention on information contained in its latter half, and in so doing, can produce more positive attitudes than traditional, uninterrupted ads. However, findings also suggest that the effects of split ads may be confined to particular conditions favoring limited processing and may be somewhat fleeting.
Coseismic DInSAR Analysis of the 2020 Petrinja Earthquake Sequence

Interferometric SAR analysis provides an excellent opportunity to perform large-scale and rapid coseismic deformation mapping. Between December 28-30, 2020, three earthquakes with magnitudes greater than 4.3 occurred during the 2020 Petrinja Earthquake Sequence near Petrinja in Croatia, resulting in significant coseismic deformation. Considering both the available ascending and descending Sentinel-1A/B images preceding and following the Petrinja Earthquake Sequence, 2.5D differential interferometric analysis was performed to determine the resulting deformation field, which have significant importance in civil engineering related countermeasures and hazard assessment. With the applied methodology, the derived horizontal and vertical deformation fields can be characterized by a maximum of ±0.43 m local East-West, a maximum of 0.15 m local subsidence and a maximum of 0.19 m local vertical uplift near Petrinja.
Effect of Ion and Binding Site on the Conformation of Chosen Glycosaminoglycans at the Albumin Surface

Albumin is one of the major components of synovial fluid. Due to its negative surface charge, it plays an essential role in many physiological processes, including the ability to form molecular complexes. In addition, glycosaminoglycans such as hyaluronic acid and chondroitin sulfate are crucial components of synovial fluid involved in the boundary lubrication regime. This study presents the influence of Na+, Mg2+ and Ca2+ ions on human serum albumin–hyaluronan/chondroitin-6-sulfate interactions examined using molecular docking followed by molecular dynamics simulations. We analyze chosen glycosaminoglycans binding by employing a conformational entropy approach. In addition, several protein–polymer complexes have been studied to check how the binding site and presence of ions influence affinity. The presence of divalent cations contributes to the decrease of conformational entropy near carboxyl and sulfate groups. This observation can indicate the higher affinity between glycosaminoglycans and albumin. Moreover, domains IIIA and IIIB of albumin have the highest affinity as those are two domains that show a positive net charge that allows for binding with negatively charged glycosaminoglycans. Finally, in discussion, we suggest some research path to find particular features that would carry information about the dynamics of the particular type of polymers or ions.
