Authors: Zhou Jinrong 
Published: October 2021

SummaryThe wireless network environment has become increasingly complex, diverse, and dynamic. In recent years, the introduction of new concepts such as green networks and smart networks has diversified the optimization objectives of the spectrum resource management. Under this background, this paper proposes the novel deep learning‐driven distributed communication systems for cluster online educational platform considering human–computer interaction. Before the modeling, the literature review and the state‐of‐the‐art methodologies are introduced. For the framework design, first, the novel distributed communication system is designed considering the integration of the Q‐learning under the deep neural network structure. Then, the cluster computing model is integrated for the system to enhance the robustness. Later, the human–computer interaction together with the movement tracking models is proposed to finalize the interactive online platform. The simulation results show that the proposed algorithm can extract the information accurately, and transmission efficiency is guaranteed. Compared with the latest platforms, the proposed outperforms from the aspects of accuracy and efficiency.
Competing characters of Li+‐Glyme complex in a solvate ionic liquid: High stability in the bulk and rapid desolvation on an electrode surface

Published: October 2021

AbstractSolvate ionic liquids (SILs) composed of glymes and Li salts are potential electrolyte materials for Li ion batteries. Safety and durability of SIL‐based batteries can be realized by competing characters of solvate cations. Solvate structure of Li+ should be stable in the bulk to be nonvolatile, and its desolvation should occur rapidly on electrode surfaces which is considered as a rate‐limiting step in charging or discharging. To investigate such characters, potential‐dependent interfacial structure of [Li(G4)][TFSA], equimolar mixture of tetraglyme and lithium bis(trifluoromethanesulfonyl)amide, on an Au electrode has been investigated at the molecular scale by using surface‐enhanced infrared absorption spectroscopy. Despite discrete solvate ion [Li(G4)]+ is stable in the bulk, partial desolvation of Li+ on the electrode was observed at around the potential of zero charge, much more positive than Li+ reduction reactions. The driving force of the partial desolvation can be ascribed to the breaking of isotropic dielectric environment in the vicinity of the electrode, where image charge induced on the electrode surface stabilizes the partially desolvated structure enabling shorter Li+‐electrode distance.
Optimization of continuous variable crown work roll shifting strategy using k‐nearest neighbors algorithm for hot strip rolling mill
Authors: Gong Dian‐yao , Li Feng‐hua 
Published: October 2021

AbstractAppropriate work roll shifting strategy in the finishing hot strip mill can make roll wear uniform and contour smooth. To eliminate the problem of roll shifting position duplication due to available roll shifting strategy, the optimized work roll shifting strategy is proposed in the hot strip rolling mill with continuous variable crown work rolls, using the k‐nearest neighbors algorithm. The self‐perpetuating parameter is used to describe the concentrated wear of the work roll. The position repeated parameter is put forward to evaluate the roll shifting position history. The relationship between concentrated shifting positions and uneven roll wear is analyzed based on in‐site data collected in a hot strip rolling mill. The program of optimization strategy is coded using language C. Off‐line simulation is made to obtain optimized shifting positions using the program. The comparison between in‐site engineering data and optimized shifting positions has been assessed using the scatter diagram and kernel density estimation. Comparison results show that the new strategy can solve the problem of shifting position duplication well. A simplified method is established to make it easy to apply the strategy to online applications, and the in‐site application shows that the optimization strategy has an excellent practical effect.

AbstractIt is elusive whether clonal selection of tumor cells in response to ionizing radiation (IR) is a deterministic or stochastic process. With high resolution clonal barcoding and tracking of over 400 000 HNSCC patient‐derived tumor cells the clonal dynamics of tumor cells in response to IR was analyzed. Fractionated IR induced a strong selective pressure for clonal reduction which significantly exceeded uniform clonal survival probabilities indicative for a strong clone‐to‐clone difference within tumor cell lines. IR induced clonal reduction affected the majority of tumor cells ranging between 96% and 75% and correlated to the degree of radiation sensitivity. Survival to IR is driven by a deterministic clonal selection of a smaller population which commonly survives radiation, while increased clonogenic capacity is a result of clonal competition of cells which have been selected stochastically. A 2‐fold increase in radiation resistance results in a 4‐fold (P < .05) higher deterministic clonal selection showing that the ratio of these parameters is amenable to radiation sensitivity which correlates to prognostic biomarkers of HNSCC. Evidence for the existence of a rare subpopulation with an intrinsically radiation resistant phenotype commonly surviving IR was found at a frequency of 0.6% to 3.3% (P < .001, FDR 3%). With cellular barcoding we introduce a novel functional heterogeneity associated qualitative readout for tracking dynamics of clonogenic survival in response to radiation. This enables the quantification of intrinsically radiation resistant tumor cells from patient samples and reveals the contribution of stochastic and deterministic clonal selection processes in response to IR.

Published: October 2021

AbstractFactors affecting the alignment of information systems (ISs) and organizational strategies (i.e., strategic alignment) vary depending on the organizational contexts, comprising both the structural and environmental contexts. Previous studies of strategic alignment were largely focused on organizations with flatter organizational structures and low environmental uncertainty. Therefore, findings from previous studies might not be applicable to organizations with tall organizational structures and in uncertain environments, like Iranian organizations. To this end, we aimed to discover less‐explored factors in achieving strategic alignment based on the contexts of Iranian organizations, using grounded theory. We conducted semi‐structured interviews with 29 experts in different organizations to illustrate and substantiate the development of an eightfold framework that specifies the factors for achieving strategic alignment. Specifically, the developed eightfold framework resulted in identification of 8 factors and 51 elements in achieving strategic alignment. Here, we identified five factors in achieving strategic alignment in addition to the factors reported by previous research (i.e., senior management, communication, and partnership), namely IS leadership, IS capabilities, organizational development, human resources, and IT infrastructure. The results indicate that these factors play a prominent role in determining the challenges and discerning the momentous requirements for achieving strategic alignment in organizations with tall structures in uncertain environments.

AbstractAffected by climate change and human activities, the frequency and uncertainty of extreme precipitation have shown an increasing trend, which has brought great challenges to the prevention of flood disasters. The Huaihe River Basin (HRB) is located at the junction of northern and southern China and is more susceptible to climate change. In order to obtain the spatio‐temporal distribution characteristics of extreme precipitation in the HRB, in this study, the L‐moments method was used to analyse the regional frequency distribution of the annual precipitation (YP), the maximum one‐day rainfall (RM1day), the maximum five‐day rainfall (RM5day) and the maximum 15‐day rainfall (RM15day) in the HRB. The results show that the HRB can be divided into five sub‐zones on the basis of the division of natural sub‐basins to ensure regional consistency. The accuracy of quantile estimation will decrease as the return periods increase. When the return period is less than 100 years, the relative root mean square error (RMSE) can be guaranteed to be relatively small, and the cumulative RMSE is less than 0.3. However, after the return period is greater than 100 years, the 90% confidence interval of the quantile estimate increases rapidly, indicating that the estimated quantile error increased. The northwestern part of the HRB may experience extreme annual precipitation, which is different from the normal precipitation distribution. The extreme precipitation in Zone 1, Zone 2–2 and Zone 4 is not only strong but also has a large increase speed, making these areas the key focus zones for flood control and anti‐logging. This study can provide important reference for the prediction and prevention of extreme precipitation in the HRB.

Objectives/HypothesisTo determine the impact of vestibular schwannoma (VS) position relative to the internal auditory canal (IAC) on postoperative facial nerve function and extent of surgical resection.Study DesignRetrospective chart review.MethodsRetrospective review of patients undergoing resection of large (≥25 mm) VSs. Outcome measures included early (≤1 month) facial function, long‐term (≥1 year) facial function and extent of resection. Tumor measurements included the greatest dimension, dimension anterior to the IAC axis, dimension posterior to the IAC axis, and a ratio of posterior‐to‐anterior dimension (PA ratio).ResultsA total of 127 patients met inclusion criteria. In early follow‐up, 60% patients had good (House‐Brackmann I–II), and 40% patients had poor (House‐Brackmann III–VI) facial function. In long‐term follow‐up, 71% patients had good, and 29% patients had poor facial function. A total of 72% of patients underwent gross total resection (GTR) of their tumors. Patients with good facial function had significantly larger PA ratios than patients with poor function both early and long term; however, greatest dimension was the more clearly significant independent predictor of facial outcomes. A larger PA ratio was observed in patients in whom GTR was achieved, but this association was potentially confounded by surgeon preferences and was not statistically significant after controlling for surgical site.ConclusionsThis study demonstrates that VS position relative to the IAC axis can be used along with tumor size to predict postoperative facial outcomes. A greater proportion of tumor posterior to the IAC axis was associated with significantly better facial outcomes.Level of Evidence4 Laryngoscope, 132:1093–1098, 2022

AbstractObjectivePost‐tonsillectomy pain is a common morbidity in children. The aim of this study was to compare the efficacy of celecoxib with acetaminophen on pain relief in pediatric day‐case tonsillectomy.MethodsWe compared the analgesic effect of celecoxib (99 patients) with acetaminophen (100 patients) for the management of post‐tonsillectomy pain. Post‐tonsillectomy pain score was evaluated three times a day for 7 days. In addition, the incidence of post‐tonsillectomy bleeding and the rate of patients who returned to regular diet were evaluated.ResultsIn the first day, we observed lower mean pain score in the celecoxib group, than the acetaminophen group (P =  0.013). The overall pain score in other days was not significantly different between the two groups. In the celecoxib group, more patients resumed regular amount of oral intake within the first 3 days. Also, the rate of post‐tonsillectomy bleeding in the two groups was not statistically different.ConclusionWe recommend celecoxib as a more suitable choice than acetaminophen for post‐tonsillectomy pain management in the first day and resuming regular diet within 3 days.Level of Evidence: 1b.

Epistaxis was the commonest complication (6.51%) from the nose while canal abrasion (5.92%) was common from the ear.ConclusionEar, nose, and upper esophageal FBs were found more frequently in younger children. The ear was the most common anatomic site of FB impaction followed by the nose and upper esophageal. The most common type of FB was cereals or seeds.Level of Evidence4.
Recurrent large‐scale sea urchin mass mortality and the establishment of a long‐lasting alternative macroalgae‐dominated community state
Authors: Sangil Carlos , Hernández José Carlos 
Published: October 2021

AbstractRelationships between sea urchins and noncrustose macroalgae are typically nonlinear, and an abrupt phase shift from a barren to a macroalgae‐dominated state and vice versa happens when the sea urchin abundance exceeds a critical threshold. Here, we have used two mass mortality events as a natural experiment to study progressive changes and dynamics between these stable states. In 2009–2010 and 2018, two mass mortalities decimated the populations of the sea urchin Diadema africanum in the Canary Islands (Eastern Subtropical Atlantic). In these islands, this sea urchin is a key‐herbivore controlling the growth of macroalgae, and sea urchin barrens have persisted for more 60 yr. Mass mortality events differed in intensity both in space and time, and two phase shifts from sea urchin barrens to macroalgal beds were detected in both when sea urchin density declined below a critical threshold of 4 indv. · m−2. The first mass mortality was greater in La Palma Island, consequently in this island a long‐lasting alternative state dominated by noncrustose macroalgae has been established. Subsequently, a recurrent mass mortality also favored the transition from the sea urchin barrens to noncrustose macroalgal beds in Tenerife Island. After mass mortalities, D. africanum populations were reduced by 94–98% in both islands. No signs of recovery of these populations have been identified after phase shifts; ecosystem feedbacks may be the cause of the low population density of D. africanum.

Published: October 2021

AbstractMechanoluminescence (ML) is the light generation of a material under mechanical stimuli. For more than 400 years, many compounds including inorganic and organic materials present this phenomenon. The general mechanism for the ML emission is the stress‐induced electrification effect combined with the piezoelectric field that lead to trapping and detrapping of the charge carriers. However, an in‐depth investigation and research are required to understand and hypothesize the ML mechanisms and optimum design and synthesis methods for better ML properties. Among the most common materials possessing this phenomenon is the zinc sulfide (ZnS) compounds that show high luminescence intensity and reproducibility. Such properties make them best candidates to be used in potential applications such as light and display devices, stress sensors, and human health monitoring devices. Therefore, this minireview focuses on the recent development and progress in doped ZnS ML compounds, including mechanism, design and synthesis, and the practical applications of such materials.
Two shock models for single‐component systems subject to mutually dependent failure processes
Authors: Bian Lina , Wang Guanjun , Liu Peng , Duan Fengjun 
Published: October 2021

AbstractIn this paper, the extreme and shock models are studied, in which systems are subject to dependent hard failure and soft failure processes. Under the extreme shock model, a hard failure occurs if the magnitude of a single shock surpasses a critical level, while under the shock model, a hard failure occurs if the interval time between two successive shocks is smaller than a threshold. Under both shock models, soft failure of a system happens if the total volume of degradation surpasses a given soft failure threshold. The hard and soft failure processes are interdependent owing to the fact that external shock will bring abrupt increment in the degradation path of the system, and on the other hand, the amount of total degradation will affect the hard failure threshold of the system. The failure of the system occurs if a hard failure or a soft failure occurs, whichever happens first. The reliability expressions of the systems under two shock models are derived explicitly. Some reliability indices of the system are calculated by utilizing the probability analysis method. A case study of the sliding spool is provided to illustrate the proposed model.
Policy implications of willingness to pay for sustainable development of a world agricultural heritage site: The role of stakeholders' sustainable intelligence, support, and behavioral intention

Published: October 2021

AbstractThe willingness to pay (WTP) for preservation of a Globally Important Agricultural System, Jeju Batdom, South Korea is estimated. To help control for hypothetical bias, two scenarios are used, hypothetical and real settings. Further, this study investigates how the concepts of sustainable intelligence, residents' support, and behavioral intention affect WTP in addition to demographic variables. Finally, three types of preservation values (bequest, option, and existence) are examined to identify how each value influences WTP. As expected, the results reveal that WTP of the hypothetical setting is larger than the real setting. The explanatory variables of sustainable intelligence, residents' support, and behavioral intention significantly increase the WTP for preservation of Batdam. Implications are clear for the preservation of agricultural heritage sites, developing programs to increase residents' sustainable intelligence, support, and behavioral intention will increase WTP for preservation. Furthermore, the Jeju residents place the highest weight on bequest value, followed by option and existence values. The findings provide researchers and practitioners with important implications when they implement sustainable development of agricultural heritage resources.

Published: October 2021

AbstractSelf‐healing hydrogels were prepared by mixing the difunctionalized polyethylene glycol (DF‐PEG) and chitosan (CS) in water. Due to the formation of Schiff base bond between DF‐PEG and CS, the gelation could be realized in several seconds. Determined by the SEM showed that the hydrogel was composed of porous network structure. The dynamic formation and dissociation of Schiff base bond (−C=N−) between the aldehyde group of DF‐PEG and amino group of CS initiated the excellent self‐healing property and reversible pH responsivity of hydrogels. Additionally, the hydrogels had excellent ductility and toughness with the fracture strain and stress of 88.2 % and 12.1 kPa. The hydrogels exhibited excellent strain sensing performance, which can be fabricated as the flexible sensor for real‐time monitoring the large and delicate human motions. As a result, it is expected that the obtained self‐healing hydrogels will broaden the application of gels in wearable electronics.

AbstractRacemic cloprostenol methyl ester was converted via cyclic 9,11‐phenylboronate esters to 9α,11α‐dihydroxy‐15α‐siloxy (OTBDPS, OTBDMS) derivatives. TES‐Morf selectively reacts with last compounds to exclusively give 11‐TES derivative. In the course of further transformations, the J‐type PG was obtained. The optimal conditions for the 13,14‐double bond shift in the latter were determined and ▵12 derivatives were obtained. 15‐TBDMS derivative PGJ2 was converted to the target ω‐aryloxy derivatives ▵12‐PGJ2, its 13Z isomer, and ▵12,14‐PGJ2 by hydrolysis of the TBDMS protective group. The anticancer activity of some of the synthesized compounds was studied.
