A Task-Driven Approach to Unified Synthesis of Planar Four-Bar Linkages Using Algebraic Fitting of a Pencil of G-Manifolds

This paper studies the problem of planar four-bar motion approximation from the viewpoint of extraction of geometric constraints from a given set of planar displacements. Using the Image Space of planar displacements, we obtain a class of quadrics, called Generalized- or G-manifolds, with eight linear and homogeneous coefficients as a unified representation for constraint manifolds of all four types of planar dyads, RR, PR, and PR, and PP. Given a set of image points that represent planar displacements, the problem of synthesizing a planar four-bar linkage is reduced to finding a pencil of G-manifolds that best fit the image points in the least squares sense. This least squares problem is solved using Singular Value Decomposition. The linear coefficients associated with the smallest singular values are used to define a pencil of quadrics. Additional constraints on the linear coefficients are then imposed to obtain a planar four-bar linkage that best guides the coupler through the given displacements. The result is an efficient and linear algorithm that naturally extracts the geometric constraints of a motion and leads directly to the type and dimensions of a mechanism for motion generation.Copyright © 2013 by ASME
New exact solutions of the generalized fractional Zakharov-Kuznetsov equations

In this paper, the new extended trial equation method is used to solve nonlinear fractional partial differential equations. Based on the fractional derivative and traveling wave transformation, the fractional partial differential equation is turned into the nonlinear non-fractional ordinary differential equation. From here, we apply the new extended trial equation method, which is developed by the complete discrimination system for polynomial method, to this nonlinear non-fractional ordinary differential equation. As a result, some new exact solutions to this nonlinear problem are successfully constructed such as the elliptic integral function
Arabic Translation Works in Expressing a Resistance: Case Study in Colonized Land Poetry of Nizar Qabbani

This research examined the poetry written by Nizar Qabbani in Arabic, which has been translated into Bahasa Indonesia. The investigation was related to how the expression of resistance from the source language into the target language can be used as one of the main media against a regime. This study used a qualitative approach. The data in this study are language units in the form of phrases, clauses, and sentences, in the source language (Arabic) and the target language (Bahasa Indonesia). Data analysis used the Spradley model, namely domain analysis, taxonomic analysis, componential analysis, and cultural analysis to find the relationship and meaning between the expression of resistance in poetry and aspects of micro and macro translation. The findings attempted to map what translation techniques appear in the expression of resistance in political poetry and how the tendencies of these techniques are at a macro level, whether the translation technique is more oriented towards the source language or the target language. The contribution of the research theoretically tries to show that literary works are an effective and elegant medium in conveying criticism of the government. The study of translation techniques should consider a particular literary genre, as literary genres influence the use and selection of translation techniques.
Adaptive mesh refinement method based investigation of the interaction between shock wave, boundary layer, and tip vortex in a transonic compressor

Shock wave and tip leakage are important flow features at small length scales. These flow phenomena and their interactions play important roles in the performance of modern transonic fans and compressors. In most numerical predictions of these features, mesh convergence studies are conducted using overall performance data as criteria. However, less effort is made in assessing the quality of the predicted small-scale features using a mesh that yields a fairly accurate overall performance. In this work, this problem is addressed using the adaptive mesh refinement (AMR) method, which automatically refines the local mesh and provides very high resolution for the small-scale flow feature, at much less cost compared with globally refining the mesh. An accurate and robust AMR system suitable for turbomachinery applications is developed in this work and the widely studied NASA Rotor-37 case is investigated using the current AMR method. The complex interactions between the shock wave and the boundary layer, as well as those between the shock wave and the tip vortex, are accurately captured by AMR with a very high local grid resolution, and the flow mechanisms are analyzed in detail. The baseline mesh, which is considered to be “acceptable” according to the commonly used mesh convergence study, is unable to capture the detailed interaction between the shock wave and the boundary layer. Moreover, it falsely predicts the tip leakage vortex breakdown, which is a consequence of inadequate resolution in the tip region. Current work highlights the importance of a careful check of the mesh convergence, if small-scale features are the primary concern. The AMR method developed in this work successfully captures the flow details in the transonic compressor in an automatic fashion, and has been verified to be efficient compared with the globally mesh refinement or manually mesh regeneration.
HOW LITERATE AM I ABOUT ASSESSMENT: EVIDENCE FROM INDONESIAN EFL PRE-SERVICE AND IN-SERVICE TEACHERS

Language Assessment Literacy (LAL) for teachers is a pivotal content area which teachers must have for their prefessional development. Despite increasing interest in language assessment, research focusing on LAL of pre-service and in-service teachers, especially in Indonesian EFL context, has yet to receive due attention. Nevertheless, understanding pre-service and in-service teachers’ literacy of classroom assessment is essential for the quality of classroom assessment practice, hence the improvement of language learning and teaching. This study aimed to investigate Indonesian EFL pre-service and in-service teachers’ literacy of classroom assessment. Using a quantitative approach with ex-post facto research design, this study examined the extent of assessment literacy among EFL pre-service and in-service teachers. Participants were 60 English department students who have done teaching practicum courses and 41 in-service teachers in the Indonesian province of East Java. The finding revealed that the pre-service and in-service teachers perceived a moderate level of assessment literacy. Further, the two groups of participants demonstrated a statistically significant difference in overall assessment literacy, as well as in two of its dimensions, namely administering and scoring assessment results and alternative assessment. The findings of this study could shed light to the understanding of EFL pre-service and in-service teachers’ literacy of classroom assessment.
Search for the critical point of strongly interacting matter through power-law fluctuations of the proton density in NA61/SHINE

The search for experimental signatures of the critical point (CP) of strongly interacting matter is one of the main objectives of the NA61/SHINE experiment at the CERN SPS. In the course of the experiment, an energy (beam momentum 13A -- 150/158A GeV/c) and system size (p+p, p+Pb, Be+Be, Ar+Sc, Xe+La) scan is performed. Proposed observables include non-monotonic fluctuations of integrated quantities, as well as local critical fluctuations connected to the critical behavior of the order parameter in the neighborhood of the CP, which scale according to universal power-laws. We investigate proton density fluctuations as a possible order parameter of the phase transition in the neighborhood of the CP. To this end, we perform an intermittency analysis of the proton second scaled factorial moments (SSFMs) in transverse momentum space. A previous analysis of this sort revealed significant power-law fluctuations in the NA49 heavy ion collision experiment for the "Si"+Si system at 158A GeV/c. The fitted power-law exponent was consistent with the theoretically expected critical value, within errors, a result suggesting a baryochemical potential for the critical point in the vicinity of ~250 MeV. We now extend the analysis to NA61 systems of similar size, Be+Be and Ar+Sc, at 150A GeV/c. We adapt statistical techniques for the calculation of scaled factorial moments, in order to subtract non-critical background and enhance the signal in cases of low statistics. Our analysis is supplemented by both critical and non-critical Monte Carlo simulations, through which we estimate non-critical background effects on the quality and magnitude of uncertainties of the intermittency power-law fit, as well as explore the possibility of non-critical effects producing an intermittency signal.
Cognitive Functional Remote Group intervention for adults with attention deficit hyperactivity disorder: A feasibility study

Introduction: Attention deficit hyperactivity disorder among adults has been associated with deficits in executive functioning and poor quality of life. The purpose of this study is to examine feasibility of the Cognitive Functional Remote Group intervention among adults with attention deficit hyperactivity disorder. Method: Mixed-method feasibility study. Five adults with attention deficit hyperactivity disorder received 16 weekly sessions of Cognitive Functional Remote Group. Results: The target population was easily recruited and showed interest in the treatment. All participants completed the intervention and were moderately-very highly satisfied with different aspects of the intervention. Additionally, pre–post measures demonstrated high rates of clinically significant improvements in the quality of life measure and less so in executive functioning. Three central themes emerged from qualitative analyses of participants experiences relating to (a) Identity development through group process; (b) Occupation-based learning of self-awareness and cognitive functional strategies and (c) Feedback on group setting and content and relating to advantages and disadvantages of remote (Zoom) format. Conclusion: This study supported Cognitive Functional Remote Group feasibility among adults with attention deficit hyperactivity disorder. Quantitative findings point to the responsiveness of quality-of-life measures. Qualitative findings suggest gains in identity development, awareness and acquisition of cognitive functional strategies through occupation-based learning in a telerehabilitation group therapy format. Further controlled studies are warranted.
Drug treatment service procurement: A systematic review of models, goals, and outcomes

Aim: To explore the goals and outcomes of public procurement of drug treatment services in OECD countries. The study explores how these complex services are procured and delivered. Methods and data: A systematic review of the literature (1990–2020) identified four partly overlapping models of drug treatment service procurement that are here labelled traditional, value-based, outcome-based, and innovative. Results: Even though different forms of drug treatment services procurement are common, only 12 empirical studies that focused on procurement were found. The four models differ in their approaches to design and performance specifications and the role of competition and collaboration in the co-creation of value. Conclusions: Competition and incentives improve neither the efficiency nor the quality or the outcomes of complex drug treatment services. Whereas many studies focus on payment mechanisms, there are important research gaps that relate to the co-creation of value with and for the service-users and other stakeholders.
Application of path-integral quantization to indistinguishable particle systems topologically confined by a magnetic field

We demonstrate an original development of path-integral quantization in the case of a multiply connected configuration space of indistinguishable charged particles on a 2D manifold and exposed to a strong perpendicular magnetic field. The system occurs to be exceptionally homotopy-rich and the structure of the homotopy essentially depends on the magnetic field strength resulting in multi loop trajectories at specific conditions. We have proved, by a generalization of the Bohr-Sommerfeld quantization rule, that the size of a magnetic field flux quantum grows for multi loop orbits like $(2k+1)\frac{h}{c}$ with the number of loops $k$. Utilizing this property for electrons on the 2D substrate jellium we have derived upon the path integration a complete FQHE hierarchy in excellent consistence with experiments. The path-integral has been next developed to a sum over configurations, displaying various patterns of trajectory homotopies (topological configurations), which in the nonstationary case of quantum kinetics reproduces some unclear formerly details in the longitudinal resistivity observed in experiments.
Enhancement of near-cloaking. Part III: Numerical simulations, statistical stability, and related questions

The goal of this paper is to illustrate the efficiency and the stability of the near-cloaking structures proposed in [4] and [5]. These new structures are, before using transformation optics, layered structures and are designed so that their first contracted generalized polarization tensors (in the quasi-static limit) or scattering coefficients (in the case of the Helmholtz equation) vanish. Inside the cloaking region, any target has near-zero boundary or scattering cross section measurements. We numerically show that this new construction significantly enhances the invisibility cloaking effect for the conductivity and the Helmholtz equations and is quite robust with respect to random fluctuations of the material parameters around their theoretical values. We finally extend our multi-coated construction to the enhanced reshaping problem. We show how to make any target look like a disc with homogeneous physical parameters.

Significant hypomethylation of MMP9 gene promoter in patients with systemic lupus erythematosus

Objective Scholars are exploring novel diagnostic and prognostic biomarkers with higher sensitivity and specificity for systemic lupus erythematosus (SLE). In this regard, DNA methylation alterations have aroused attention. The association between the dysfunction of MMP9 and TNFAIP3 genes and SLE has been previously demonstrated. Therefore, in this study, we investigated the methylation level of MMP9 and TNFAIP3 promoters in peripheral blood mononuclear cells (PBMCs) of SLE patients and healthy controls. Methods Eighty Iranian SLE patients and 77 healthy individuals were enrolled. The methylation quantification endonuclease-resistant DNA (MethyQESD) method was used to assess methylation levels of MMP9 and TNFAIP3 in extracted DNA of PBMCs. To quantify the diagnostic utility of the promoter methylation level of these genes, the receiver operating characteristic (ROC) curve was constructed. Results MMP9 promoter was significantly hypomethylated in SLE patients compared with healthy people (p < 0.001), while there was no significant difference in terms of TNFAIP3 promoter methylation levels (p = 0.167). Also, this differential MMP9 methylation was observed in patients with renal involvement and patients without renal involvement (42.07 ± 25.73 vs 56.74 ± 29.71, p = 0.007). ROC analyses indicated that the diagnostic power of the MMP9 promoter methylation level for SLE was 0.839 [95% CI (0.781–0.911)]. Moreover, MMP9 methylation level was negatively correlated with creatinine and anti-dsDNA concentration and positively correlated with C3 and C4 levels. Conclusion The results of this study highlight the application of MMP9 methylation level in PBMCs of SLE patients as a diagnostic biomarker.
Spokewise iridotomy combined with Descemet stripping automated endothelial keratoplasty in iridocorneal endothelial syndrome

Purpose Iridocorneal endothelial (ICE) syndrome is a progressive anterior segment disorder that can be tricky to treat. Keratoplasty is commonly used to treat corneal edema in ICE syndrome. However, glaucoma is an important risk factor affecting graft survival. To address this question, we designed a retrospective cohort study to evaluate the effect of Spokewise Iridotomy (SI) on Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) Grafts in Iridocorneal Endothelial (ICE) Syndrome. Methods This was a retrospective cohort study. A total of 29 patients were included; 31 eyes with ICE syndrome underwent DSAEK at Peking University Third Hospital between June 2015 and June 2022, including 11 eyes with combined SI during DSAEK. The aim was to explore the effect of SI on vision, glaucoma control, complications, peripheral anterior synechiae recurrence, endothelial cell count, and graft survival. Results The median follow-up time was 30.83 months (mo.) in the SI+Endothelial Keratoplasty (EK) group and 6.17 mo in the EK group. The 2-year cumulative survival rate of grafts in the SI+EK group was 100%, compared with the 6-month and 1-year cumulative survival rates of 80.2 and 63.2%, respectively, in the EK group (p = 0.043). The SI+EK group had a lower incidence of immediate postoperative complications (p = 0.005), fewer postoperative anti-glaucoma medications (AGMs) (p = 0.029), smaller peripheral anterior synechiae recurrence (p = 0.001), and significant visual acuity improvement (p < 0.05). More AGMs were used in failed grafts (p = 0.002). Conclusion SI can help control intraocular pressure, improve visual acuity, and increase graft survival after DSAEK in ICE syndrome patients.
Effectiveness of nursing virtual training courses based on the Kirkpatrick Model

BACKGROUND: Educational evaluation is one of the most significant programs of any organization. In fact, evaluating training effectiveness allows managers and staff of the organization to get a clear picture of the qualities of training activities. The purpose of this study was to evaluate virtual nursing intensive care training courses at Shariati Hospital based on the Kirkpatrick Model in 2020. METHODS AND MATERIAL: The current cross-sectional study is an evaluation of the outcome-oriented program to evaluate the results of the e-learning course on nursing intensive care at Shariati Teaching Hospital from March 20, 2020 to September 20, 2020. The total number of nurses working in intensive wards was 168, of whom 150 participated in this research study with convenience sampling. The data collection tool consisted of four-part questionnaires including demographic information and three levels of the Kirkpatrick Model. RESULTS: The mean age of participants was 34.41 ± 6.63 years. The mean score of participant satisfaction was 76.77, indicating that they showed good reaction to virtual training courses. Virtual training course for intensive care nurses was statistically significant at the levels of learning (P < 0.0001) and behavior (P < 0.0001). CONCLUSIONS: Virtual training courses are effective educational method based on three levels of Kirkpatrick's Model in intensive care nurses and it can be used along with traditional training approaches.

Existence of Diffusions on 4N Carpets

Following the methods used by Barlow and Bass to prove the existence of a diffusion on the Sierpinski Carpet, we establish the existence of a diffusion for a class of planar fractals which are not post critically finite. We conjecture that specific resistance estimates hold on our class of fractals. We further conjecture that these resistance estimates imply the existence of the spectral dimension for our class of fractals. Under these assumptions we use the methods of Barlow and Bass to establish heat kernel asymptotics. From there, we can use the techniques of Barlow, Bass, Kumagai, and Teplyaev to show the uniqueness of the diffusion up to scalar multiples. As a corollary, we conjecture the existence and uniqueness of a diffusion on the Octagasket, thus partially answering a question posed by Strichartz.

Observation and interpretation of energetic ion conics in Jupiter's polar magnetosphere

NASA's Juno spacecraft successfully completed its first science polar pass over Jupiter's northern and southern aurora, with all the instruments powered, on 27 August 2016. Observations of conical energetic proton distributions at low altitudes (<6 RJ) over the northern polar region are interpreted as resulting from transversely (to the local magnetic field lines) accelerated H+ at a position planetward of the point of observation. The proton conics were observed within a broad region of upward beaming electrons and were accompanied by broadband low‐frequency wave emissions as well as low‐altitude trapped magnetospheric protons and heavy ions. The characteristic energies associated with these accelerated ion conics are ~100 times more energetic than similar distributions observed in the Earth's auroral region and similar in energy to those found at Saturn. In addition, the ion conics also exhibited pitch angle dispersion with time that is interpreted as a consequence of the structure of the source location. Mapping these distributions along magnetic field lines connected from the spacecraft to the ionosphere suggests that the source region exists at altitudes between ~3 and 5 RJ. These new and exciting observations of accelerated ions over the polar region of Jupiter open up new areas for comparative planetary auroral physics.
A Column Generation Approach to Correlated Simple Temporal Networks

Probabilistic Simple Temporal Networks (PSTN) represent scheduling problems under temporal uncertainty. Strong controllability (SC) of PSTNs involves finding a schedule to a PSTN that maximises the probability that all constraints are satisfied (robustness). Previous approaches to this problem assume independence of probabilistic durations, and approximate the risk by bounding it above using Boole’s inequality. This gives no guarantee of finding the schedule optimising robustness, and fails to consider correlations between probabilistic durations that frequently arise in practical applications. In this paper, we formally define the Correlated Simple Temporal Network (Corr-STN) which generalises the PSTN by removing the restriction of independence. We show that the problem of Corr-STN SC is convex for a large class of multivariate (log-concave) distributions. We then introduce an algorithm capable of finding optimal SC schedules to Corr-STNs, using the column generation method. Finally, we validate our approach on a number of Corr-STNs and find that our method offers more robust solutions when compared with prior approaches.
