On Some Neighbourhood Degree-Based Multiplicative Topological Indices and Their Applications

Abstract In this paper, we mainly concern with some neighborhood degree-based multiplicative topological indices that are introduced by some eminent researchers in the past three years. According to the suggestion of the “International Academy of Mathematical Chemistry,” we tested their predictive ability of physicochemical properties of molecules with the help of a data set of octane isomers. Here, we also modified the general fifth multiplicative Zagreb index as a new one and computed this index for some line graphs of subdivision graphs of some union graphs of hexagons. Hence, computed some other multiplicative topological indices with the help of this index.
Digital versus Traditional Workflow for Immediate Loading in Single-Implant Restoration: A Randomized Clinical Trial

Simple Summary Immediate loading is nowadays a diffused technique in implantology. At the same time, digital dentistry is rapidly spreading, especially in what concerns prosthetic rehabilitation. The present study aimed to compare, through a randomized clinical trial design, the analogical vs. the traditional workflow. Single-implant restorations have been run in 50 patients, with a 12-month maximum period of follow-up after implant placement. Data were analyzed through radiological, clinical, and customer satisfaction evaluation. Importantly, and surprisingly enough, no statistically significant differences emerged between the two kinds of workflow. When assessing customer satisfaction, however, patients clearly and significantly preferred the comfort of the digital vs. traditional workflow. Abstract The purpose of this randomized controlled trial was to compare the immediate-loading protocol, in single restorations in the esthetic zone, by comparing the digital workflow in a test group (TG) vs. the analogical workflow in a control group (CG). A total of 50 patients were enrolled, requiring single hopeless tooth extraction. Twenty-five patients (TG) were randomly assigned to the immediate-loading protocol using the digital workflow, and twenty-five patients (CG) were assigned to the conventional workflow. Clinical and radiographic parameters were evaluated at the time of implant insertion (baseline) and after 3, 6 and 12 months, respectively. A clinician blind to conditions measured the Pink Esthetic Score (PES), as well as patient satisfaction. At 12-month follow-up, a cumulative survival rate of 100% was reported for all implants. No failures or biological complications were observed. No statistically significant differences were detected in the mean values of marginal bone loss and PES between the TG (0.12 ± 0.66 mm for MBL, 7.75 ± 0.89 for PES) and the CG (0.15 ± 0.54 mm for MBL, 7.50 ± 0.89 for PES). In 11 cases of TG, and 10 cases of CG, a one-year follow-up period showed an increased marginal bone level. No statistically significant differences were found in the mean total PES between test (7.75 ± 0.89) and control (7.5 ± 0.81) conditions. Furthermore, a customer satisfaction survey showed that patients preferred the digital workflow over the conventional workflow procedure (97.6 ± 4.3 vs. 69.2 ± 13.8). Digital workflow was more time-efficient than conventional workflow (97.2 ± 7.3 vs. 81.2 ± 11.3). Within the limitations of this study, no statistically significant differences were found between digital and traditional workflow.
Fast high-power/high-voltage switch using series-connected IGBTs with active gate-controlled voltage-balancing

There exists an acute need for fast high-voltage solid-state switches in a broad area of applications. With the proposed method of active gate-controlled voltage balancing, fast high power/high voltage semiconductor switches with working voltages of several kilovolts using series-connected insulated gate bipolar transistors (IGBT) can be realized. Transient and static voltage balancing is tested on an experimental 3.5 kV/300 A switch with three series-connected 3rd-generation IGBTs. <<ETX>>
Methods to Reduce Traffic Speed in High-Pedestrian Rural Areas

Many Minnesota counties are faced with the problem of high vehicle speeds through towns or resort areas that have significant pedestrian traffic. The impact of speed reduction strategies in high-pedestrian areas in rural counties of Minnesota was investigated. Speed data were collected at two selected study sites under their existing conditions ("no-treatment" or "before" condition) and after the proposed speed reduction strategies were installed. Second "after" data conditions were collected to study the short-term and long-term impact of the implemented strategies. The traffic-calming techniques employed at the Twin Lakes site consisted of removable pedestrian islands and pedestrian crossing signs. A dynamic variable message sign that sent a single-word message ("Slow") to motorists traveling over the speed limit was installed at the Bemidji site. The research study shows that the traffic-calming strategy deployed in Twin Lakes was effective in significantly reducing the mean speed and improving speed limit compliance in both the short term and long term. Despite proven effectiveness, the deployed speed reduction treatment in Bemidji Lake failed to lower the speed at the study site. The single-word message on the sign and the location of the sign, as well as a lack of initial enforcement, were the primary reasons for such failure.
‘Many pieces one family’: An elaboration of one family’s bereavement experiences

There has been considerable research on bereavement and the concept of continuing bonds. However, there is a distinct absence of research considering bereavement, continuing bonds and family dynamics post-bereavement. The paper reports on a study utilising a family systems approach combined with narrative methods, tools of conversation analysis and systemic theory. This integration of approaches is used to consider how one family offers an account of their experience of bereavement. An exploration of their conversation along with visual presentation in the form of button sculpts is employed. The findings support the suggestion that it is useful to consider bereavement experiences as part of a family system. Clinical implications of the research are outlined to consider how best to support bereaved families.

High-voltage UMOSFETs in 4H SiC

We report the design and fabrication of UMOSFETs on 4H-SiC with specific on-resistances of 105.1 m/spl Omega/ cm/sup 2/ at a current density of 100 A/cm/sup 2/ and blocking voltage of 5,050 V. These devices incorporate an extended self-aligned p-bottom implant to protect the gate oxide from high electric fields. A novel shadow implant mask was developed to shield the sidewalls from any unwanted p-bottom implant. These UMOSFETs are also the first to incorporate a post-oxidation anneal (POA) in nitric oxide (NO) to improve the inversion layer electron mobility. A single zone JTE (junction termination extension) with peak blocking voltage of 7,500 V was implemented in the device design.
Neuroprotective Effect of Clobenpropit against Lipopolysaccharide-Induced Cognitive Deficits via Attenuating Neuroinflammation and Enhancing Mitochondrial Functions in Mice

Clobenpropit (CLO), an antagonist on histamine H3 receptors (HH3R), has been shown to protect NMDA-induced neuronal necrosis in cortical neuronal cell culture from rats. In this work, we explored its potential on lipopolysaccharide (LPS)-induced memory deficits, neuroinflammation, and mitochondrial dysfunction in mice. CLO (1 and 3 mg/kg, p.o.) was treated continually for 30 days, and neurotoxicity was induced by four doses of LPS (250 µg/kg, i.p.). The radial arm maze (RAM) was used to access memory behaviors. After the REM test, brain tissue was collected from each mouse to estimate pro-inflammatory cytokines (TNFα and IL6), anti-inflammatory cytokines (TGF-β1 and IL-10), cyclooxygenase-2 (COX 2), and mitochondrial respiratory chain complex (MRCC- I, II and IV) enzymes. CLO treatment reversed the LPS-induced behavioral deficits by a significant reduction in time taken to consume all five bites (TTB), working memory error (WME), and reference memory error (REM) in the REM test. Regarding neuroinflammation, it attenuated the release of COX, TNF-α, and IL-6, and augmented TGF-β1 and IL-10 levels in the brain. Reversal of LPS-induced brain MRCC (I, II, and IV) levels also resulted with CLO treatment. From these findings, CLO promises neuroprotection against LPS-induced cognitive deficits by ameliorating neuroinflammation and restoring the MRCC enzymes in mice.
Defining and characterising the nurse–patient relationship: A concept analysis

The nurse-patient relationship involves complex attitudes and behaviours with ethical and deontological implications. It has been linked to improvements in patient health outcomes, although there is still no consensus in the scientific literature as to the definition and characterisation of the concept. This article aim to define the concept of the nurse-patient relationship. A concept analysis was conducted using the Walker and Avant method to identify the attributes defining the nurse-patient relationship. An integrative review of the literature was conducted using the PubMed, Web of Science, Scopus, and Cumulative Index to Nursing & Allied Health Literature databases. A review of the grey literature and other minor non-indexed publications on the topic was also conducted. A total of 36 articles were included in the review. A model case, a contrary case, a related case, and empirical references were produced to clarify the concept and identify its essential attributes. The concept is defined as a helping relationship involving interaction between different players. It is the basis of nursing care and is intended to meet the healthcare needs of the individual receiving this care. It is also viewed as an intervention in itself, requiring a specific training process just like any other nursing skill. The essential attributes of the relationship are empathy, presence, contact, authenticity, trust, and reciprocity. In conclusion, the nurse-patient relationship is a helping relationship established with the patient and/or their family based on interaction, communication, respect for ethical values, acceptance, and empathy in order to encourage introspection and behavioural change. Key components include communication, active listening, and respect. Bioethical values and confidentiality must also be present to ensure that the relationship is built on equality and intimacy.
Variation in the performance of multispan 10-Gb/s systems due to the group delay ripple of dispersion compensating fiber Bragg gratings

The variation in the performance of multispan lightwave systems that use dispersion-compensating fiber Bragg gratings (FBGs) is characterized in terms of the peak-to-peak group delay ripple over the -1dB bandwidth of the gratings. The irregular dependence of the group delay ripple on wavelength, and the variability in the properties of the group delay ripple for nominally identical gratings make it difficult to predict the overall reflection spectrum for a cascade of gratings. The uncertainty in the overall spectrum must be considered in the system design process. By considering 2401 distinct configurations for the gratings in a four-span 320-km system, simulation results are presented that specify the requirement for the group delay ripple in order for the system performance to remain within a specified penalty.
From Hilbert’s 13th problem to essential dimension and back

goes back to ancient times. Here by “solving" I mean finding a procedure or a formula which produces a solution x for a given set of coefficients a1, . , an. The terms “procedure" and “formula" are ambiguous; to get a well-posed problem, we need to specify what kinds of operations we are allowed to perform to obtain x from a1, . , an. In the simplest setting we are only allowed to perform the four arithmetic operations: addition, subtraction, multiplication and division. In other words, we are asking if the polynomial (1) has a root x which is expressible as a rational function of a1, . , an. For a general polynomial of degree n > 2, the answer is clearly “no"; this was already known to the ancient Greeks. The focus then shifted to the problem of “solving polynomials in radicals", where one is allowed to use the four arithmetic operations and radicals of any degree. Here the mth radical (or root) of t is a solution to
Postoperative cytokine levels and their predictive value in critical patients after major abdominal surgery: a retrospective cohort study.

BACKGROUND It remains uncertain as to what impact cytokine expression level has on patient outcomes. The association of serum levels of interleukin-1β (IL-1β), IL-2, IL-6, IL-8, IL-10, tumor necrosis factor-α (TNF-α), and procalcitonin with critically ill patient outcomes after major abdominal surgery still need to be explored. METHODS From January 1, 2018 to June 30, 2019, a retrospective cohort study was conducted on patients admitted to the surgical intensive care unit (SICU). Levels of IL-1β, IL-2, IL-6, IL-8, IL-10, TNF-α, and procalcitonin were assessed in 1,228 patients undergoing major abdominal surgery with blood samples drawn within 24 h after surgery. RESULTS Of the 1,228 patients admitted to the SICU for the first time, 1,152 survived and 76 patients died, with a mortality rate of 6.2% (76/1,228). The results of univariate and multivariate analyses revealed that non-survivors had higher levels of IL-1β (OR =2.438, P<0.001) and IL-2 (OR =1.561, P=0.006). Of 62 (5.0%) readmitted to the SICU, the data of 59 were collected, and showed 46 patients survived and 13 died, giving a mortality rate of 22.0% (13/59), which was 3.5 times higher than the mortality rate during the first SICU admission. Serum IL-6 level associated with SICU readmission (OR =1.37, P=0.029). Furthermore, non-survivors had a longer SICU stay and higher rates of mechanical ventilation and continuous renal replacement therapy (CRRT). CONCLUSIONS High levels of IL-1β and IL-2 were associated with mortality, and a high level of IL-6 was a risk factor for SICU readmission in critically ill patients who underwent major abdominal surgery. The mortality rate was higher during the second SICU stay.
Attitude and perception of post-graduate residents toward thesis: A cross-sectional study

Background: To increase research productivity among post-graduate (PG) students, there is inclusion of research dissertation or thesis in their academic curriculum. However, thesis or research project during the residency remains is the last priorities due to high demands on the PG student’s energy and time in terms of patient care. There are a very few such studies conducted in our nation pertaining to perception of PG students toward thesis. Aim and Objectives: This study is to assess the attitude and perception of medical PG residents toward research dissertation or thesis during residency training. Materials and Methods: This was an observational, cross-sectional study with the 2nd and 3rd year MS/MD PG students as participants. Study tool was pre-validated questionnaire consisting 40 questions under following domains: University regulations (5), attitude toward thesis (4), perception toward benefits of thesis (15), perception toward obstacles of thesis (13), and practice in regard to thesis (3). A study was initiated after approval of Institutional Ethics Committee. After obtaining written informed consent, a questionnaire was given to each student and was collected after 25–30 min. Confidentiality of responses was ensured by maintaining anonymity of responders. Data were entered into Excel and a descriptive analysis was done. Results: Of these 55 pre/paraclinical and 70 clinical PG students (n = 125) returned completely filled questionnaire. The mean age of the students was 27.40 ± 2.20 and was in the 2nd or 3rd year of the residency. 256% participants were from clinical whereas 44% were from pre/paraclinical branches. The majority of postgraduate students preferred observational studies (80%) over interventional study for thesis (19.2%). 61.6% PG students felt that thesis should be mandatory. Majority of students agreed to benefit of thesis which helps them to develop skills such as literature search (92.8%), data processing (84%), statistical analysis (73.6%), interpretation of results, and discussion (80.8%). PG students felt that there are few obstacles in their thesis such as inadequate lab facilities (66.4%), inadequate study tools (62.4%), and incompetent technical staff (55.2%). Conclusion: A number of barriers such as lack time, funding, and poor availability of research facilities for conduct of research need to be addressed to further enhance PG student’s positive attitude toward thesis.
Developing Passenger-Car Equivalents for Heavy Vehicles in Entry Flow at Roundabouts

AbstractThis study develops passenger-car equivalents (PCEs) for heavy vehicles at roundabouts. For this task, the movements of cars and heavy vehicles were observed using video records collected from three roundabouts in Vermont; Ontario, Canada; and Wisconsin. The PCE was developed such that the variation in the entry capacity in a various mix of cars and heavy vehicles was minimized. The PCE was also applied to the prediction of the entry capacity using a roundabout capacity model. For the model inputs, the study adjusted the critical headway and the follow-up headway to account for the difference in driver’s gap acceptance behavior between cars and heavy vehicles. The result shows that the PCEs for heavy trucks and light trucks are 1.5–2.5 and 1.0–1.5, respectively, at the three roundabouts. In particular, the PCE for light trucks was lower than a default value of 2.0. The result also shows that the established model generally predicted the capacity more accurately when the critical headway and the fo.
Relationships between Plantar Pressure Distribution and Rearfoot Alignment in the Taiwanese College Athletes with Plantar Fasciopathy during Static Standing and Walking

Background: Plantar fasciopathy (PF) is usually related to changes in foot arch, foot shape and rearfoot posture. However, little research has been implemented by using large-scale datasets, and even less has been conducted centering on plantar pressure distributions (PPDs) of different genders of PF athletes. This study aimed to investigate the relationships among the arch index (AI), the PPDs and the rearfoot postural alignment in hundreds of college athletes with PF during static standing and walking. Methods: Cross-sectional study of 100 male and 102 female athletes with PF was undertaken. The PF athletes’ pain assessment and self-reported health status were examined for evaluating their musculoskeletal painful areas. Results: The PF athletes’ PPDs mainly concentrated on inner feet in static standing, and transferred to lateral forefeet during the midstance phase of walking. The males’ PPDs from the static standing to the midstance phase of walking mainly transferred to anterolateral feet. The females’ PPDs mainly transferred to posterolateral feet. The PF athletes’ static rearfoot alignment matched the valgus posture pattern. The medial band of plantar fascia and calcaneus were the common musculoskeletal pain areas. Conclusions: Characteristics of higher plantar loads beneath medial feet associated with rearfoot valgus in bipedal static stance could be the traceable features for PF-related foot diagrams. Higher plantar loads mainly exerted on the lateral forefoot during the midstance phase of walking, and specifically concentrated on outer feet during the transition from static to dynamic state. Pain profiles seem to echo PPDs, which could function as the traceable beginning for the possible link among pronated low-arched feet, PF, metatarsalgia, calcanitis and Achilles tendinitis.
Exploring family language policymaking of internal migrant families in contemporary China: negotiating habitus, capital and the social field

ABSTRACT Drawing on semi-structured interviews with six Chinese migrant families with children aged 12–15 years old, this qualitative study uses a Bourdieusian lens to probe how the historically lived and migration experiences of Chinese internal migrant parents construct their paradoxical beliefs in children’s English learning and informs their family language practice. The discursive process of constructing family language policy (FLP) reveals how migrant parents negotiate between changing habitus and the newly acquired capital during migration to Shanghai. Findings indicate that the migrant parents acknowledge the value of English in the linguistic market and hold high expectations and aspirations of their children’s English education. However, their historically constructed language ideologies constrain their engagement in children’s English learning and hinder their FLP decision-making. The urban field’s prevailing social and educational norms of promoting children’s learning English as a foreign language to enhance cross-cultural communication and attain academic success has its transformative power, which enables migrant parents to adjust their understanding of English learning and encourages them to facilitate the same for their children at home. The present study proposes a theoretical model to conceptualise the FLP construction in internal migrant families. Implications of the findings for different stakeholders have been discussed.
