Using Geostatistics to Map Received Power in Wireless Communication Networks

— The literature analysis of propagation models has investigated different prediction methods to identify appropriate techniques for this purpose. The predictive algorithms of these models usually deal with large amounts of data, requires a sophisticated computer processing and knowledge, sometimes detailed of the topography of the terrain. For being based on measurements performed at specific locations, empirical models tend not to provide very reliable results when applied to regions that differ significantly from the original region This article proposes a method based on measured data that incorporates the effects of neighborhood on the calculation of received power (dBm) and uses the theory of geostatistics to estimate the extent of the spatial correlation between measurements of samples in the region of interest. The results show that it is possible to identify the vectors with better reception of the signal emitted by the base transceiver station by the spatial perspective of received power measurements (dBm) and to identify homogeneous zones and those zones where the service operator may or may not favor the user.
No creative person is an island

This paper examines the relationship between perceptions of organisational culture, academics’ social embeddedness and their creative paper project output. It argues that the extent to which researchers working on paper projects are socially embedded throu gh social ties with colleagues inside and outside their academic department (but within the same university) is a causal step linking organisational values and norms to creative outputs. This study does not, however, find support for the proposed mediating effects. Instead, results indicate that three organisational culture dimensions – i.e. performance orientation, environmental orientation and innovation support – affect employees’ creative project output through their social embeddedness outside the depa rtment (but within their own university). As the organisational culture and social embeddedness of employees outside the department are both contextual factors that matter (either indirectly or directly) for the generation of creative project outputs by re searchers, this study concludes that “no creative person and no project is an island”.
Optimizing Student-Faculty Rapport for the Engineering Classrooms: Dimensioning the Behaviors That Matter

This research paper describes the findings from an exploratory study. Student retention in engineering disciplines, from program initiation through commencement, is recognized as a challenge by higher learning institutions across the US. Numerous studies have identified that professors who can establish strong and positive rapport with their students have an immediate and positive impact on students’ learning, engagement, motivation and academic success, resulting in a positive long-term influence on retention. Previous work has defined fifteen specific faculty behaviors that establish positive rapport between students and professors in other disciplines. However, these past studies may not be generalizable for engineering, and fall short of identifying the differences across student academic maturity and engineering discipline. Given the potential for strong impact on engineering students’ experiences, and faculty resource limitations, we sought to elucidate if some behaviors have a higher potential for impact than others, and if so, which faculty behaviors may best contribute to building faculty-student rapport. With these insights, engineering faculty can be trained to selectively focus on those which are expected to have the greatest return on investment. To support the primary aim, students from multiple disciplines in an engineering college were surveyed and asked to rank their perceptions of faculty behaviors that best establish rapport with engineering students. The survey asked students to self identify their gender. This was used to identify how these factors may influence ranking of rapport supportive behaviors. Additionally, this survey asked students both their academic program (the discipline within engineering) and their degree progression, in order to identify how these factors impact such rankings. Based on findings in the literature, and given the scope of this project, the authors anticipate that the most effective way to broaden students’ retention in engineering education is through establishing rapport between engineering professors and their students. Using the results of this study, we can design interventions aimed at faculty member’s ability to establish positive rapport, which in turn creates a respectful environment, and removes the barriers to cultivation of diverse student retention in engineering disciplines.
Lean Thinking from Toyota Manufacturing to the Healthcare Sector

Purpose: This paper aims to provide a historical overview of how lean thinking has transferred and spread from Toyota manufacturing to the healthcare sector. It aims to explain the origin of lean: how it is defined, the main tools, concepts, and principles behind it, provide some lean healthcare examples, and explore the differences between the manufacturing and healthcare systems. Design/methodology/approach: The article reviews current literature for lean application in healthcare from five databases. More than 60 articles and books were considered according to a taxonomy suggested. Findings: Lean originated from Toyota in the 1940s due to the need to increase production efficiency, specifically by reducing waste. Since then, lean has expanded to other industries and organisations, gradually advancing to services and, since the beginning of the twenty-first century, have also been used in the healthcare sector. While the philosophy was introduced to the world by Toyota, the term ‘lean’ was only introduced by Jon Krafcik in the late 1980s. Lean initially lacked an agreed-upon definition within the literature; any agreement reached was on the potential of lean thinking in the healthcare sector. Several lean tools and techniques were used by different organisations, mostly to reduce or eliminate waste. Some of the leading examples of lean healthcare include the United States of America’s (USA) Virginia Mason Medical Centre, Theda Care in Wisconsin (USA), Bolton Hospital in England, and the Saskatchewan health care system in Canada. Even with the encouraging success stories from adopting lean as a management approach, several challenges still remain. The healthcare sector differs greatly from the motor industry as hospitals are not factories, so the transition between the two is not straight forward. Originality/Practical implications: This literature review is helpful for journal editors and reviewers, researchers in healthcare organisations and healthcare practitioners as it offers a comprehensive, historical overview of how lean thinking has transformed and spread from Toyota manufacturers to the healthcare sector.
Puppetry as an Alternative Approach to Designing Kinesthetic Movements

: ‘Kinesthetic empathy’ refers to the experience of kinetic sensations of observed movements. It becomes a useful lens for designers to explore the aesthetic quality of the movements of designed objects (e.g. fans, doors, clocks, robots) from an embodied perspective. It also empowers them to imagine and create alternative beings of everyday objects and their movements. In this way, it could eventually lead to rethinking our embodied relationship to the artificial world, especially physical movements of objects and spaces. This paper presents a practice-based research in which four product designers including the author proposed imaginative kinetic products informed by kinesthetic empathy. Rather than moving quickly from ideation to prototyping functional, mechanical motions, our approach was experimental, i.e. we conducted a more flexible and intuitive exploration of movements in collaboration with ‘unusual’ partners for product designers-puppeteers. The collaborative design process exposed us to unseen benefits and challenges of adopting puppetry as a means to design kinesthetic movements of objects. By bringing together each practitioner’s reflection on their design processes and outcomes, the paper concludes by proposing a new design approach to kinesthetic movements that bridges product design and puppetry.
Compact Extended Industrial Range CMOS Current References

This paper presents two new compact current reference circuits for use in extended industrial range from −45 °C to 125 °C. The first reference circuit implements very simple first order correction. The circuit parameters can be obtained by relatively simple calculations. The circuit is well suited for generation of currents equal to several <inline-formula> <tex-math notation="LaTeX">$\mu \text{A}$ </tex-math></inline-formula>. The measurement results of two realizations for the generation of 1 <inline-formula> <tex-math notation="LaTeX">$\mu \text{A}$ </tex-math></inline-formula> and 24 <inline-formula> <tex-math notation="LaTeX">$\mu \text{A}$ </tex-math></inline-formula> currents were performed. The circuits achieve a competitive temperature compensation of < 200 ppm/°C in the wide operating temperatures range from −45 ° to 125 °C. The second reference uses more advanced second order correction. The circuit was also verified by design and measurement of 230 nA current reference. Ten samples were measured through the extended industrial temperature range of −45 ° to 125 °C. The minimum measured temperature coefficient value is 221 ppm/°C with a median value of 669 ppm/°C. All test circuits were designed in standard 0.35 <inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> CMOS technology of AMS.
Abnormal muscle tension as one of the main problems after a stroke

Background: Stroke is a growing problem in an aging society. According to WHO data, it is the second most common cause of death. An increase in the number of strokes causes an increase in the number of patients struggling with its consequences. People who have suffered a stroke are dealing with various neurological defects. One of them is abnormal muscle tension. Material and methods: Analysis of available literature, articles in the Google Scholar and PubMed database using keywords: stroke, muscle tension, spasticity. Results: The problem of disturbed tension is common in people who have had a stroke. Spasticity, i.e. increased muscle tone in response to stretching, results from damage to the central nervous system. Direct and indirect methods are used to assess spasticity. In the fight against destroyed muscle tension, it is important to implement treatment as soon as possible. It is based on the use of various forms of therapy: pharmacotherapy and physiotherapy. Physiotherapy and kinesitherapy treatments as well as specialized rehabilitation methods, such as PNF. The rehabilitation process should be supplemented with appropriate pharmacological treatment. Equally important is the implementation of stroke prevention. These activities are associated with the promotion of a healthy lifestyle, for example, regular exercise and stress reduction. Conclusion : Muscle tension disorder, including spasticity, is a problem affecting many patients who have had a stroke. A timely diagnosis is important to get the right therapy. Treatment should have a holistic dimension and combine different methods. The goal of therapy is to normalize muscle tone and thus improve the patient's quality of life.
Quantitation of Radiolabeled Component Binding to Bacteria

It has been recognized since 1895 (1) that some gram-negative bacteria are sensitive to the lytic action of fresh serum, whereas others are highly serum resistant. In general, serum-resistant organisms are more pathogenic than serum-sensitive bacteria in animal models of infection, and serum-resistant organisms are more commonly isolated from the bloodstream of patients with gram-negative bacteremia (2). In attempts to define the basis of this important virulence factor, characteristics of the outer membrane of serum-sensitive and serum-resistant organisms have been analyzed and compared (3-5). The presence of a complete lipopolysaccharide (LPS) 1 (i.e., the smooth phenotype) is the characteristic most clearly associated with serum resistance. Rough bacteria lacking a complete LPS are almost invariably serum sensitive. The antibody and complement requirements for serum killing of bacteria also have been examined. It has been shown (6-8) that killing of gram-negative bacteria by serum requires the participation of terminal components of the complement system ((25-9). However, the mechanism of resistance of gram-negative bacteria to serum killing in the presence of adequate antibody is still unknown. Resistance to serum killing could involve the inability to form a membrane attack complex on the organism. An alternative hypothesis, however, is that a membrane a t t ack complex that forms on the bacterial surface may be functionally impotent either because of failure to insert into the bacterial outer membrane or because the inserted complex does not cause damage to vital outer or inner membrane structures. Previous studies have examined a number of aspects of this issue. Studies have suggested that serum-sensitive and serum-resistant strains of Escherichia coli (9, 10) or Salmonella typhimurium (11) have equivalent amounts of C3 deposited. It is not resolved whether (25 is deposited on serum-resistant bacteria. Reynolds et al. (11) could not demonstrate deposition of functional C5 on serum-resistant S. typhimurium in Mg ++ saline after incubation in C6-deficient rabbit serum. On the other hand, Ogata and Levine (10) demonstrated equivalent (25 consumptior~ by strains of E. coli that varied in complement sensitivity; however, evidence for levels of cell-bound (25 was not
Should the Full Array of Steroid Hormones be Measured in Trauma Research? A Pilot Study

Objectives: This pilot study was designed to determine whether future trauma research should gather information on the full array of steroid hormones. Methods: Blood levels of cortisol, DHEA, testosterone, pregnenolone, estradiol and sex hormone binding globulin were obtained in a sample of 67 hospital trauma program inpatients. Results: High and low blood levels of all hormones except pregnenolone were observed, with the most frequent being cortisol: 13 participants had high resting morning cortisol, and 6 had low levels. Conclusions: Although the uncontrolled and cross-sectional nature of the data do not allow conclusions about causality, it appears that, in future studies of trauma physiology, blood levels should be obtained for the full array of steroid hormones, rather than for just cortisol and DHEA; these two steroid have received the most attention in prior trauma research. We hypothesized that if cortisol and DHEA are dysregulated in trauma survivors, perhaps abnormalities in other steroid hormones might occur in this population. Our uncontrolled, cross-sectional methodology does not allow us to reach any causal conclusions, or to attribute causality to the participants’ psychological trauma, but we nevertheless thought it would be instructive to examine the steroid hormone system as a whole in a sample of trauma survivors. This study is analogous to an open label pilot study in pharmacology.
CCL22/CCR4 Interactions Involvement of the CTLA-4/B7 and Functional Cells of Mesenteric Lymph Nodes: Constitutive Expression of IDO by Dendritic

Dendritic cells (DCs) express the immunoregulatory enzyme IDO in response to certain inﬂammatory stimuli, but it is unclear whether DCs express this enzyme under steady-state conditions in vivo. In this study, we report that the DCs in mesenteric lymph nodes (MLNs) constitutively express functional IDO, which metabolizes tryptophan to kynurenine. In line with a previous report that regulatory T cells (Tregs) can induce IDO in DCs via the CTLA-4/B7 interaction, a substantial proportion of the MLN DCs were located in juxtaposition to Tregs, whereas this tendency was not observed for splenic DCs, which do not express IDO constitutively. When CTLA-4 was selectively deleted in Tregs, the frequency of IDO-expressing DCs in MLNs decreased signiﬁcantly, conﬁrming CTLA-4’s role in IDO expression by MLN DCs. We also found that the MLN DCs produced CCL22, which can attract Tregs via CCR4, and that the phagocytosis of autologous apoptotic cells induced CCL22 expression in CCL22 mRNA-negative DCs. Mice genetically deﬁcient in the receptor for CCL22, CCR4, showed markedly reduced IDO expression in MLN-DCs, supporting the involvement of the CCL22/CCR4 axis in IDO induction. Together with our previous observation that MLN DCs contain much intracytoplasmic cellular debris in vivo, these results indicate

Testing Hybridization Hypotheses Based on Incongruent Gene Trees

— Hybridizationis an importantevolutionarymechanisminplantsandhasbeen increasingly documented in animals. Dif(cid:142)culty in reconstruction of reticulate evolution, however, has been a long-standing problem in phylogenetics. Consequently, hybrid speciation may play a major role in causing topological incongruence between gene trees. The incongruence, in turn, offers an opportunity to detect hybrid speciation. Here we characterized certain distinctions between hybridization and other biological processes, including lineagesorting, paralogy, and lateral genetransfer,thatareresponsible
ANTI-INFLAMMATORY EFFECT OF BETEL QUID ON MUCOSAL WOUND OF MALE WISTAR ( RATTUS NOVERGICUS ) RATS

Objective: True experimental in vivo with pre-test and post-test control group design was conducted at Animal House of Medical Faculty of Sriwijaya University Palembang and Biomedical Science Laboratory of Palembang, South Sumatera. Methods: Thirty rats were divided into five groups; three groups were treated with betel quid ointments at concentration of 5%, 10% and 20%, one group was positive control (hyaluronic acid) and last group was negative control (placebo). One-mm diameter of wound was made on lower lip mucosa of rats with cylinder diamond bur. Wound was induced with carrageenan. The number of neutrophils was counted on the first day and third day after treatment by using hematoanalyzer. Results: There was a significant decrease of the number of neutrophils for respective groups (p<0.05). Betel quid ointment of 10% and 20% concentration had similar effect to 0.2% hyaluronic acid (p>0.05). Conclusion: Betel quid has an anti-inflammatory effect on the mucosal wound of rats in a dose-dependent manner.
Clinical evaluation of ultrasonic subgingival debridement and ultrasonic subgingival scaling combined with manual root planning in patients with periodontitis: study protocol for a randomized controlled trial

Background: Periodontal diseases are regarded as the most common diseases of mankind. The prevalence rate of periodontal disease assumes the obvious growth tendency in the whole world, increased by 57.3% from 1990 to 2010. Thereby, effective periodontal therapy is still a long-term task and tricky problem. The goals of periodontal therapy are to eliminate the infectious and inflammatory processes. Root planning, in order to eliminate the “infected cementum”, is an important step in treatment of periodontitis since 1970s. Along with the understanding of endotoxin’s feature on root surface, the necessity of manual root planing has been gradually queried. Ultrasonic instruments wouldn’t remove the cementum excessively, which are more time-saving and labor-saving compared to hand instruments as well. Hence, an increasing number of dentists prefer to scaling with ultrasonic instruments only. However, the necessity of root planing has still been emphasized in the international mainstream views of periodontal mechanical treatment. Therefore, this study is devoted to compare the clinical effect of ultrasonic subgingival debridement and ultrasonic subgingival scaling combined with manual root planing, which taking the implementation of root planing as the only variable and more in line with the clinical situation, hoping to provide some reference to dentists. Methods/design: Forty adult patients who fit the inclusion criteria are being recruited from the Peking University Hospital of Stomatology (Beijing, China). By means of randomization tables, one quadrant of the upper and lower teeth is the test group and the other is the control group. Test group: ultrasonic subgingival scaling combined with manual root planing. Control group: ultrasonic subgingival debridement. In a 24-weeks follow-up period, plaque index, probing depth, clinical attachment loss, bleeding index, furcation involvement, mobility, and patient-reported outcome (visual analog scale for pain and sensitivity) will be observed and documented. Discussion: This study evaluates the effectiveness of ultrasonic subgingival scaling combined with manual root planing and ultrasonic subgingival debridement alone in nonsurgical treatment of periodontitis with a split-mouth design after 1, 3 and 6 months. The result of the trial will potentially contribute to an advanced treatment strategy of periodontitis with ideal clinical outcome. Trial registration: The study has been registered in International Clinical Trials Registry Platform (ICTRP) under the identifier number ChiCTR1800017122. Registered on 12 July 2018.
