Warehouse location selection by fuzzy multi criteria decision making methodologies based on subjective and objective criteria
Year: 2016

This paper proposes three new extended fuzzy multi criteria decision making methodologies capable of handling subjective and objective factors for the evaluation and selection of warehouse location. A warehouse location selection problem involves both subjective as well as objective criteria. The concept of fuzzy set theory is integrated with the Technique for Order Preference by Similarity to the Ideal Solution (TOPSIS) Simple Additive Weight (SAW) and Multi Objective Optimization on the basis of Ratio Analysis (MOORA) methods to assess subjective criteria in terms of subjective factor measures. A classical normalization technique is employed to assess the objective criteria in terms of objective factor measures. Subjective factor measures and objective factor measures are integrated by the Brown and Gibson model to calculate the warehouse location selection index. The proposed methods are illustrated with two examples of warehouse location selection. A comparative study of the results and a sensitivity analysis are carried out. The study finds that the proposed methodologies are useful and effective fuzzy multi criteria decision making tools for the evaluation and selection of warehouse location in a supply chain.
Randomized Trial on Comparison of the Efficacy of Extracorporeal Shock Wave Therapy and Dry Needling in Myofascial Trigger Points
Venue: American journal of physical medicine rehabilitation
Year: 2019

Supplemental digital content is available in the text.  The aim of the study was to compare the efficacy of radial extracorporeal shock wave therapy and dry needling in the treatment of myofascial trigger points in the upper trapezius muscle.  A total of 65 patients with myofascial trigger points were randomly divided into extracorporeal shock wave therapy group (n 32) and dry needling group (n 33) Patients received 3 wks of treatment at 1 wk intervals (in both groups) Visual analog scale, pressure pain threshold, Neck Disability Index, and shear modulus were evaluated before treatment, immediately after the first therapy, 1 mo, and 3 mos after the completion of the third therapy.  Significant improvements of visual analog scale, pressure pain threshold, and Neck Disability Index scores were observed at all time points after treatment (P 0.01) in both treatment groups. The shear modulus of myofascial trigger points was reduced in both dry needling group (P 0.05) and extracorporeal shock wave therapy group (P 0.01) immediately after the first treatment. Significant reductions in shear modulus were maintained up to 3 mo posttreatment in both groups (P 0.01) There were no significant differences between the radial extracorporeal shock wave therapy group and dry needling group.  The extracorporeal shock wave therapy is as effective as dry needling for relieving pain, improving function, and reducing shear modulus for patients with myofascial trigger points after a series of three treatments.
Normal Incidence Excited Strong Coupling Between Excitons and Symmetry Protected Quasi Bound States in the Continuum in Silicon Nitride WS2 Heterostructures at Room Temperature.
Venue: The journal of physical chemistry letters
Year: 2020

Room temperature strong coupling between quasi bound states in the continuum (q BIC) of a silicon nitride metasurface and excitons in a WS2 monolayer is investigated in detail by both numerical simulations and theoretical calculations. The strong coupling between the q BIC mode and excitons leads to a remarkable spectral splitting and typical anti crossing behavior of the Rabi splitting, which can be realized in the absorption spectra by varying the grating thickness and asymmetry parameter of the silicon nitride metasurface, respectively. In addition, both the linewidth of the q BIC mode and local electric field enhancement are found to affect the strong coupling, which needs to be considered in detail in q BIC metasurface designs. This work provides a possible way to enhance light matter interactions in transition metal dichalcogenides monolayers and pave the way for future quantum and nanophotonic applications.
An Inquiry into the Influences of Pedagogical Content Knowledge and Epistemological Stance on Teachers' Approach to Teaching Fundamental Theorem of Calculus
Year: 2010

This qualitative study examined four university mathematics instructors with differing levels of educational and teaching experience. We considered data from our individual interviews with these four instructors. The analysis of these interviews lead us to discover that common influences on instructors' approach to the FTC include KCS, SCK, CCK, and personal epistemological beliefs. However, the impact of these factors may differ from instructor to instructor. The data also suggests that PCK consists of overlapping components, contrary to Hill, Ball, Schilling (2008) construct of PCK.
Treatment of ebola and other infectious diseases: melatonin "goes viral"
Year: 2020

This review summarizes published reports on the utility of melatonin as a treatment for virus mediated diseases. Of special note are the data related to the role of melatonin in influencing Ebola virus disease. This infection and deadly condition has no effective treatment and the published works documenting the ability of melatonin to attenuate the severity of viral infections generally and Ebola infection specifically are considered. The capacity of melatonin to prevent one of the major complications of an Ebola infection, i.e. the hemorrhagic shock syndrome, which often contributes to the high mortality rate, is noteworthy. Considering the high safety profile of melatonin, the fact that it is easily produced, inexpensive and can be self administered makes it an attractive potential treatment for Ebola virus pathology.

QR Codes Utilization in EFL Classroom: Affective Language Learning Attributes in Writing
Venue: Script Journal: Journal of Linguistics and English Teaching
Year: 2020

Numerous positive gains have been reported on the use of technology in language learning. The current survey of published journal articles reveals a lack of research on its integration to language teaching and learning in graduate language classrooms in EFL settings. In this study, the use of QR codes in the graduate EFL classroom has been investigated concerning its relatedness to affective language learning attributes (herein referred to as ALLAs) including anxiety, engagement, motivation, self esteem, among others during the lesson on the process of writing. Three objectives were sought (1) to know students' perceptions on ALLAs before and after the use of QR codes, (2) to establish the relationship between students' perceived ALLAs and language performance, and (3) to understand specific situations that trigger positive or negative reactions.The students were asked to indicate their perceptions concerning ALLAs by using a survey questionnaire before and after the activity. They were also asked to do the QR codes activity to create an essay outline. Further, an open ended questionnaire was provided to indicate their negative or positive reactions to specific situations during the QR coded activity.Results suggest the following (1) there are significant differences in the students' perceived ALLAs before and after the activity, (2) there is a significant positive correlation between ALLAs and language performance, and (3) twelve specific situations were found to provoke dynamic ALLAs reactions.It is suggested that the use of available technological innovations must be introduced to graduate language teachers as its impacts on ALLAs are overwhelmingly beneficial.
Efficacy and Tolerability of Eravacycline in Bacteremic Patients with Complicated Intra Abdominal Infection: A Pooled Analysis from the IGNITE1 and IGNITE4 Studies.
Venue: Surgical infections
Year: 2020

Eravacycline is a novel, fully synthetic fluorocycline antibiotic that was evaluated for the treatment of complicated intra abdominal infections (cIAI) in two phase 3 clinical trials. The objective of this analysis was to evaluate the clinical cure and microbiologic response at the test of cure (TOC) visit and the safety of eravacycline in patients with cIAI and baseline bacteremia who received eravacycline versus comparators.  Pooled data of patients with bacteremia from the Investigating Gram Negative Infections Treated with Eravacycline (IGNITE) 1 and IGNITE4 studies were analyzed. All patients were randomly assigned in a one to one ratio to receive eravacycline 1 mg/kg intravenously every 12 hours, ertapenem 1 g intravensouly every 24 hours (IGNITE1) or meropenem 1 g intravenously every eight hours (IGNITE4) for four to 14 days. Blood and intra abdominal samples were collected from all patients at baseline. Clinical outcome and microbiologic eradiation at the TOC visit (28 days after randomization) and safety in the microbiologic intent to treat population (micro ITT) were assessed.  Of 415 patients treated with eravacycline and 431 treated with carbapenem comparators, concurrent bacteremia was identified in 32 (7.7% and 31 (7.2% patients, respectively. Demographic and baseline characteristics were similar among treatment groups. In the micro ITT population, the pooled clinical response at the TOC visit for eravacycline was 28 of 32 (87.5% and was 24 of 31 (77.0% for comparators among the subgroup with baseline bacteremia (treatment difference 5.9; 95% confidence interval [CI] 6.5 to 17.4) At TOC, microbiologic eradication of pathogens isolated from blood specimens occurred for 34 of 35 (97.1% pathogens with eravacycline and 35 of 36 (97.2% pathogens with comparators. The incidence of adverse events was comparable between treated groups and similar to that observed in the non bacteremic population.  Eravacycline demonstrated a similar clinical outcome and microbiologic eradication rate as comparator carbapenems in patients with cIAI and associated secondary bacteremia. Future clinical trials of cIAI should report outcomes of this important clinical cohort (cIAI with concurrent bacteremia) given their high risk for adverse outcomes.
Characterizing large scale use of a direct manipulation application in the wild
Venue: Graphics Interface
Year: 2010

Examining large scale, long term application use is critical to understanding how an application meets the needs of its user community. However, there have been few published analyses of long term use of desktop applications, and none that have examined applications that support creating and modifying content using direct manipulation. In this paper, we present an analysis of 2 years of usage data from an instrumented version of the GNU Image Manipulation Program, including data from over 200 users. In the course of our analysis, we show that previous findings concerning the sparseness of command use and idiosyncrasy of users' command vocabularies extend to a new domain and interaction style. These findings motivate continued research in adaptive and mixed initiative interfaces. We also describe the novel application of a clustering technique to characterize a user community's higher level tasks from low level logging data.
Targeting the Blood Brain Barrier to Prevent Sepsis Associated Cognitive Impairment
Venue: Journal of central nervous system disease
Year: 2019

Sepsis is a systemic inflammatory disease resulting from an infection. This disorder affects 750 000 people annually in the United States and has a 62% rehospitalization rate. Septic symptoms range from typical flu like symptoms (eg, headache, fever) to a multifactorial syndrome known as sepsis associated encephalopathy (SAE) Patients with SAE exhibit an acute altered mental status and often have higher mortality and morbidity. In addition, many sepsis survivors are also burdened with long term cognitive impairment. The mechanisms through which sepsis initiates SAE and promotes long term cognitive impairment in septic survivors are poorly understood. Due to its unique role as an interface between the brain and the periphery, numerous studies support a regulatory role for the blood brain barrier (BBB) in the progression of acute and chronic brain dysfunction. In this review, we discuss the current body of literature which supports the BBB as a nexus which integrates signals from the brain and the periphery in sepsis. We highlight key insights on the mechanisms that contribute to the BBB's role in sepsis which include neuroinflammation, increased barrier permeability, immune cell infiltration, mitochondrial dysfunction, and a potential barrier role for tissue non specific alkaline phosphatase (TNAP) Finally, we address current drug treatments (eg, antimicrobials and intravenous immunoglobulins) for sepsis and their potential outcomes on brain function. A comprehensive understanding of these mechanisms may enable clinicians to target specific aspects of BBB function as a therapeutic tool to limit long term cognitive impairment in sepsis survivors.
In Memory PageRank Accelerator With a Cross Point Array of Resistive Memories
Venue: IEEE Transactions on Electron Devices
Year: 2020

In memory computing with cross point arrays of resistive memory is a promising technique for typical tasks, such as the training and inference of deep learning. Recently, it has been shown that a cross point array of resistive switching memory (RRAM) with a feedback configuration can be used to solve linear systems, compute eigenvectors, and rank webpages in just one step. Here, we demonstrate the PageRank with a real data set (the Harvard500) and an eight level RRAM model, describing the conductance update, the standard deviation of each level, and the conductance ratio. By carefully placing each memory conductance value via a program verify technique, we show that an accuracy of 95% can be achieved for the ranking result. The equivalent throughput of the eigenvector circuit for PageRank is estimated to be 0.183 tera operations per second (TOPS) while the energy efficiency is 362 TOPS/W. This article supports the feasibility of in memory PageRank with significant improvements in speed and energy efficiency for practical big data tasks.
Spiritual Leadership, Organizational Culture, Organizational Silence and Academic Success of the School
Venue: Educational Administration: Theory and Practice
Year: 2019

In this study, the relationships between high school teachers' perceptions of spiritual leadership, organizational culture, organizational silences and academic success of the school were tested. The population of the research, which is designed with causal model, consists of a total of 2,791 teachers working in public high schools in a province in Central Anatolia, whereas the sample consisted of 457 teachers working in 24 high schools determined by the proportional cluster sampling method. The primary data of the research were obtained using the Spiritual Leadership Scale, School Culture Inventory and Organizational Silence Scale, whereas the secondary data were obtained using the average scores of the school from the Higher Education Entrance Examination (YGS) and the Undergraduate Placement Examination (LYS) The data were tested using correlation analysis, multiple regression analysis and structural equation model. The findings of the research showed that teachers' perceptions about the spiritual leadership behaviors of the principals affected their organizational culture perception positively; the perception of the organizational culture affected the school's YGS average score positively and LYS average score negatively.
Mandatory IFRS Reporting and Changes in Enforcement
Year: 2012

In recent years, reporting under International Financial Reporting Standards (IFRS) became mandatory in many countries. The capital market effects around this change have been extensively studied, but their sources are not yet well understood. This study aims to distinguish between several potential explanations for the observed capital market effects. We find that, across all countries, mandatory IFRS reporting had little impact on liquidity. The liquidity effects around IFRS introduction are concentrated in the European Union (EU) and limited to five EU countries that concurrently made substantive changes in reporting enforcement. There is little evidence of liquidity benefits in IFRS countries without substantive enforcement changes even when they have strong legal and regulatory systems. Moreover, we find similar liquidity effects for firms that experience enforcement changes but do not concurrently switch to IFRS. Thus, changes in reporting enforcement or (unobserved) factors associated with these changes play a critical role for the observed liquidity benefits after mandatory IFRS adoption. In contrast, the change in accounting standards seems to have had little effect on market liquidity.

Flight control of a Rotary wing UAV using adaptive backstepping
Venue: 2009 IEEE International Conference on Control and Automation
Year: 2009

This paper presents a novel application of a two time scale controller, using adaptive backstepping technique, for the hover flight control of a Rotary wing Unmanned Aerial Vehicle (RUAV) Flapping and servo dynamics, important from a practical point of view, are included in the RUAV model. The two time scale controller takes advantage of the 'decoupling' of the translational and rotation dynamics of the rigid body, resulting in a two level hierarchical control scheme. The inner loop controller (attitude control) tracks the attitude commands generated by the outer loop controller and sets the main rotor thrust vector, while the outer loop controller (position control) tracks the reference position. The proposed controller uses the parameter update law of the adaptive backstepping design to approximate the external disturbances such as wind gusts. Hover flight simulation results are presented in this paper using the proposed backstepping based controller.
Acupuncture Treatment of Lateral Elbow Pain: A Nonrandomized Pilot Study
Venue: Evidence based complementary and alternative medicine eCAM
Year: 2016

In planning for a large scale multicenter trial to evaluate the effect of acupuncture for the treatment of lateral elbow pain, a pilot study was conducted. This was a prospective, investigator and patient blinded, nonrandomized, placebo controlled trial. Subjects were evaluated at baseline, before fourth, seventh, and ninth treatment, and at a two week posttreatment follow up. The treatment group received unilateral acupuncture at LI 10 and LI 11 at the affected side with manual needle manipulation; the control group received sham laser acupuncture at the same acupoints. Measures included (i) disabilities of the arm, shoulder, and hand (DASH) questionnaire, (ii) pain free grip strength (PFGS) and (iii) a visual analogue scale (VAS) for pain. Significant differences in DASH score, PFGS, and VAS between treatment and control group were found at the ninth treatment (n 20 for each group, P 0.05) Only DASH showed significant differences compared to the control for all the measurement time points after treatment commenced and appears to be a sensitive and appropriate primary outcome measure for the future multisite trial. Results from this pilot study provided relevant information about treatment efficacy, credibility of control treatment, and sensitivity of different outcome measures for the planning of the future trial.
Self Z scheme plasmonic tungsten oxide nanowires for boosting ethanol dehydrogenation under UV visible light irradiation.
Venue: Nanoscale
Year: 2019

Nonstoichiometric tungsten oxides (WO3 x) with abundant oxygen vacancies were synthesized and used as nonmetallic plasmonic photocatalysts to promote ethanol dehydrogenation under UV visible light irradiation. Plasmonic WO3 x have unique electronic structures that act as Z scheme heterostructures. UV excited photoelectrons were injected into the conduction band of WO3 x, stabilizing the free electron density and boosting plasmonic hot electron generation for ethanol dehydrogenation. The synergetic effect of UV and visible light excitations greatly enhances the aldehyde generation to 2696 mmol g 1 (3 hours) with a high selectivity of 91% which is 74 fold and 12 fold higher than those obtained under only UV or visible light irradiation, respectively.
