Collective plasmonic excitations in two- dimensional metamaterials based on near-field coupled metallic nanoparticles

L’etude des proprietes plasmoniques est un champ de recherche actuellement tres actif. En particulier, la possibilite de manipuler la lumiere a des echelles sub-longueur d’ondes rend ce domaine tres attractif. Recemment, plusieurs etudes ont montre que les plasmons collectifs dans des meta-materiaux bi-dimensionnels constitues de nanoparticules metalliques se comportaient de maniere similaire aux electrons dans les cristaux et partageaient certaines de leurs proprietes. Dans ce manuscrit, nous presentons une theorie unifiee permettant de decrire les proprietes de tels modes plasmoniques dans des reseaux ordonnes de geometrie arbitraires constitues de nanoparticules metalliques couplees en champ proche. En particulier, nous evaluons les taux de decroissance de ces modes ainsi que leurs decalages en frequence afin de predire leur observabilite experimentale.
Aging Effect on Microstructure and Machinability of Corrax Steel

In this paper, the influence of the aging process on the microstructure and machinability of Corrax Steel was investigated for four samples: a solution heat-treated (A0) and three samples aged at 400oC (A4), 525oC (A5.25) and 600oC (A6) for four hours. The effect of aging temperature on hardness was examined. Machining tests were carried out using a CNC lathe with a multi-layer coated PVD (AlTiN) cutting tool, at various cutting speeds (50, 100, 150, 200, 250, 300, 350m/min) with constant feed rate (0.1mm/rev) and 1mm constant cutting depth. The microstructure was investigated using an optical microscope and EDS attached SEM. The effect of aging on reverted austenite formation was also evaluated. In order to understand the changes in surface topology, cutting forces and vibrations were measured. With increasing aging temperature, the lath martensite was transformed to plate martensite because of the formation of precipitates and reverted austenite. Aging at different temperatures increased hardness up to 58%, cutting forces up to 117% and surface roughness up to 450%. The results describe the effect of the aging treatment on cutting forces, surface topology, tool wear and vibrations.
Experimental Investigation of the Influence of Wire Arc Additive Manufacturing on the Machinability of Titanium Parts

The manufacturing of titanium airframe parts involves significant machining and low buy-to-fly ratios. Production costs could be greatly reduced by the combination of an additive manufacturing (AM) process followed by a finishing machining operation. Among the different AM alternatives, wire arc additive manufacturing (WAAM) offers deposition rates of kg/h and could be the key for the production of parts of several meters economically. In this study, the influence of the manufacturing process of Ti6Al4V alloy on both its material properties and machinability is investigated. First, the mechanical properties of a workpiece obtained by WAAM were compared to those in a conventional laminated plate. Then, drilling tests were carried out in both materials. The results showed that WAAM leads to a higher hardness than laminated Ti6Al4V and satisfies the requirements of the standard in terms of mechanical properties. As a consequence, higher cutting forces, shorter chips, and lower burr height were observed for the workpieces produced by AM. Furthermore, a metallographic analysis of the chip cross-sectional area also showed that a serrated chip formation is also present during drilling of Ti6Al4V produced by WAAM. The gathered information can be used to improve the competitiveness of the manufacturing of aircraft structures in terms of production time and cost.
A novel adaptive control approach for path tracking control of autonomous vehicles subject to uncertain dynamics

Autonomous ground vehicles are constantly exposed to matched/mismatched uncertainties and disturbances and different operating conditions. Consequently, robustness to resist the undesirable effect of changes in the nominal parameters of the vehicle is a significant provision for satisfactory path-tracking control of these vehicles. The accomplishment of lateral path-tracking control is an essential task expectable from autonomous ground vehicles, particularly during critical maneuvers, abrupt cornering, and lane changes at high speeds. This paper presents a new control approach based on immersion and invariance control theorem. The asymptotic stability of the proposed method is ensured and the adaptation laws for the parameters are derived based on the I&I stability theorem. The effectiveness of the proposed control method is confirmed for autonomous ground vehicles systems while making a double-lane-change at various forward speeds. The robustness of the proposed control method is evaluated under parametric uncertainties related to the autonomous ground vehicle and different road conditions. The obtained results suggest that the proposed control method holds the capacity to be applied effectively to the path-tracking task of autonomous ground vehicles under a broad range of operating conditions, parametric uncertainness, and external disturbances.
Northeastern Family Forest Owner Gender Differences in Land-Based Estate Planning and the Role of Self-Efficacy

Understanding family forest owner (FFO) estate planning decisionmaking is fundamental to ensuring the survival of landscapes that provide many public goods, but little is known about how land-based estate planning differs by gender. Analyses of a survey of FFOs in northeastern United States indicated that female FFOs rate themselves with lower levels of land-based estate planning self-efficacy—being less prepared, confident, and financially able to move forward with planning the future of their land than males. Of the FFOs who had positive levels of land-based estate planning self-efficacy, females were more likely to want to keep their land undeveloped than males. Our research suggests that increasing land-based estate planning self-efficacy of female FFOs may lead to higher rates of keeping land undeveloped for regions with FFOs similar to those of the northeast. We recommend ways in which foresters and programs could play an important role in increasing land-based estate planning self-efficacy.
A Qualitative Study of New Public Spaces Among The Commuter Line Stations

Traffic jam problems and auto-dependency have become two of the main problems in Jabodetabek. Today, the main transportation system that connects the buffer cities and the City of Jakarta is the Commuter Line railway system. Soon, commuting by train will start to become part of the common urban culture in Jabodetabek and aligns with the automobile culture that has already dominated the city for years. This cultural change is causing the stations to become nodes where “railway-oriented activities” intersect with “caroriented activities. ” Additionally, the urban elements around the stations such as flyovers begin to develop. As the main aim of the flyovers are to avoid the railway crossing, they are not purposely provide shades beneath for places, but the shades have become new spots for people’s activities. People have begun to use the residual space beneath the flyover. As a result, different types of “rooms” or areas formed within the public spaces near the stations and produced a hierarchy from private to public that is similar to a “house”—but in urban context. This paper maps and analyzes the formation of the public spaces around the stations with a focus on the presence of the flyovers based on the field observations that were linked with
Ptimization of Co-immobilization of Cellulase and β-glucosidase

Cellulase can hydrolyze cellulose to produce reducing sugars such as cellobiose and cellotriose. β-glucosidas can further hydrolyze cellobiose and cellobiose produced by cellulase to produce glucose. According to the hydrolysis mechanisms of cellulase and β-glucosidas, we selected two enzyems, cellulase and β-glucosidase to study optimization of co-immobilization of cellulase and β-glucosidas. Meanwhile, we selected two materials, activated carbon and sodium alginate to co-immobilize cellulase and β-glucosidas by the immobilization method of embedding-adsorption. The immobilization conditions, alginate, CaCl2 and activated carbon was optimized. The results showed that the optimum concentrations of sodium alginate and CaCl2 were 2% and 2%, respectively, and the quality of activated carbon is 0.15 g. The optimal ratio of cellulase to β - glucosidase was 1:1.5. The results indicated that cellulase and β-glucosidase had a synergistic effect and that their compound degradation of cellulose was better than the separate effects of the two enzymes acting independently.
Understanding the use and disclosure of natural products by cancer patients

UNDERSTANDING THE USE AND DISCLOSURE OF NATURAL PRODUCTS BY CANCER PATIENTS Joshua M. Kotfila, B.Sc., M.Sc. Rutgers, The State University of New Jersey 2016 Chair: Dr. Susan Gould-Fogerite Background: Although cancer patients frequently use natural products (NP) to complement conventional oncology treatments and often do not disclose NP use to their healthcare providers, NP use initiated after diagnosis and the biopsychosocial determinants of NP use and disclosure have not been investigated. Purpose: The study purpose was to determine prevalence, patterns, and disclosure of NP use by cancer patients, and apply the SelfRegulation Model (SRM) to understand these behaviors. Methods: Analysis of a sub-set of the data from a cross-sectional survey of 1,226 cancer patients at a NCI–designated comprehensive cancer center within a 12-month period. Descriptive statistics were used for patterns of NP use and disclosure. Survey results were assigned to categories within the SRM and sequential
A critical review of bioleaching of rare earth elements: The mechanisms and effect of process parameters

Abstract Rare earth elements (REEs) are important high-tech materials with widespread industrial applications and a high risk of supply disruption. Current physico-chemical methods for REE recovery are energy intensive, complex, and costly. Thus, it is crucial to undertake measures to secure future REE demand and protect the environment as well. Bioleaching as an alternative technology for the recovery and recycling of REEs from a variety of primary and secondary sources has been increasingly explored. The present review provides an overview on REE content of various primary and secondary sources, applied bioleaching microorganisms and methods, reactor setups, as well as a detailed description of known REE leaching mechanisms. The effects of different process parameters including temperature, pH, medium composition, pulp density, and particle size on efficiency of REE leaching are also evaluated in detail.
Apomorphine in the Treatment of Parkinson’s Disease

The majority of patients with Parkinson's disease (PD) develop motor fluctuations and dyskinesias as their condition progresses. In patients where adjustments of oral (or transdermal) treatment options can no longer adequately control these motor complications, further options include deep-brain stimulation for a minority of selected patients, intrajejunal levodopa (L-dopa) application via a pump or apomorphine infusion therapy. The dopamine agonist apomorphine provides relief from off periods when administered as a subcutaneous injection. When applied continuously via a portable pump system, oral medication can often be reduced considerably and dyskinesias improve in many patients. Disclosure: Regina Katzenschlager has received fees for speaking and consulting from Britannia and Cephalon Germany. The initiation of antiparkinsonian treatment in early Parkinson's disease (PD) is followed by a phase of good to excellent symptomatic response in nearly all patients; this has been referred to as the 'honeymoon phase'. A stable response may be sustained in some patients throughout the course of their illness, but the majority will go on to develop motor complications, which include fluctuations and dyskinesias or involuntary movements. In early PD, the clinical effect following an individual levodopa (L-dopa) dose wanes slowly and may still be detectable after days to weeks. As the disease progresses, the duration of effect gradually becomes shorter and patients become aware of a missed or delayed dose as their parkinsonian symptoms and signs re-emerge ('wearing-off'). Eventually, the clinical response closely reflects peripheral L-dopa pharmacokinetics, characterised by a plasma half-life of 1–1.5 hours. More complex forms of on/off fluctuations may emerge, such as unpredictable fluctuations, delayed on or dose failures. All of these changes in motor functioning may cause considerable distress. However, off periods may be associated with non-motor symptoms, such as acute depression, dysphoria or pain, which may be even more disabling than the worsening of motor function. Dyskinesias may be present at peak doses or during the entire course of the drug. At earlier stages, they may go unnoticed by the patients while carers are aware of their presence and may be socially embarrassed. Patients themselves may prefer mild or moderate forms of dyskinesia to the immobility and non-motor symptoms of off periods, but severe chorea and more complicated patterns, such as ballistic, stereotypic and dystonic dyskinesias, pose a considerable burden on patients. Dyskinesias may be predominant at the onset and end of a dose effect (diphasic dyskinesia). Off-period dyskinesias are usually dystonic, often affect the feet …
Tremor in Parkinson's Disease: Loading and Trends in Tremor Characteristics

Parkinson’s disease (PD) is a neuro-degenerative chronic disorder with cardinal signs of bradykinesia, resting tremor, rigidity, and postural abnormality/instability. Tremor, which is a manifestation of both normal and abnormal activities in the nervous system, can be described as an involuntary and periodic oscillation of any limb. Such an oscillation with a small amplitude, which is barely visible to the naked eye, is present in healthy people. This is called a physiological tremor and is asymptomatic. This tremor is believed to be the result of at least two distinct oscillations. A passive mechanical oscillation that is produced by the irregularities of motor unit firing, and by blood ejection during cardiac systole. The frequency and amplitude of these oscillations are dependent on the mechanical properties of the limb including joint stiffness and limb inertia. There is another component of oscillation that does not respond to elastic or inertial loading, which is called the central component, and is believed to arise from an unknown oscillating neuronal network within the central nervous system. Unlike physiological tremor, pathological tremors are symptomatic and can impair motor performance. Parkinson’s disease (PD) tremor is generally manifested at rest, but also occurs during posture or motion. Classical PD rest tremor is known to be a central tremor of 4-6 Hz and peripheral origins have only a minimal role. However, whether or not the same central mechanism remains active during action tremor (including posture and movement) should yet be answered. Contrary to PD rest tremor, reported results on action tremor in the literature are diverse; and the reason for the changes in tremor characteristics in situations other than rest, or generally during muscle activation, is not fully understood. The lack of generality in the results of studies on action tremor, makes the efforts of treatment difficult, and is a barrier for mechanical/engineering approaches of suppressing this tremor. To investigate the role of mechanisms other than classic rest tremor, and possible sub-categories of tremulous PD in yielding diverse results, this study was conducted on twenty PD patients and fourteen healthy age-matched (on average) controls. To evaluate the possible contribution of (enhanced) physiological tremor, the study considered the effect of loading on postural hand tremor in a complete range of 0-100% MVC (Maximum Voluntary Contraction). The study looked at two measures of tremor amplitude and one measure of tremor frequency, and focused on two frequency bands of classic-rest (3.5-6.5 Hz) and physiological (7.5-16.5 Hz) tremors. The study revealed that PD tremor was not uniformly distributed in the three dimensional space, and then focused on the investigation of tremor in the dominant axis, which
Measuring Intra-abdominal Pressure during Spontaneous Breathing Trial: Does It Help?

Background: Respiratory system impairment may be caused by an increase of the intra-abdominal pressure (IAP). measuring 80% and 52% respectively. The Area Under the Curve (AUC) was 0.97. With multivariate regression analysis, mean IAP was an independent predictor of SBT failure (odds ratio (OR) 1.46, 95% confidence interval (CI) 1.62 to 1.839, p value 0.001). Using Spearman's rank correlation coefficient, it was found that mean IAP was positively correlated with auto ,positive end expiratory pressure, PEEP that measured at the beginning and at the end of SBT, and admission APACHE II score, with correlation coefficient measuring 0.515, 0.595, and 0.4 respectively.
HPV AND HEAD AND NECK DISEASES

The ubiquitous Human papillomavirus, HPV, is responsible of an impressively frequent infection in humans. Actually, it is estimated that nearly 440 million individuals are HPV-infected worldwide. HPV is a very complex group of pathogenic viruses as more than 120 different genotypes have been identified so far. All are epitheliotropic viruses, specifically for squamous epithelia. These genotypes have different transmission modalities (sexual or non-sexual) and induce totally different diseases (from trivial plantar warts to invasive cancers for example of the cervix). HPVs responsible for benign epithelial hyperproliferation are named “low-risk” types while HPVs associated with premalignant lesions and invasive squamous cell carcinoma are named “high-risk” types. In the head and neck region, HPV infections may result HPV AND HEAD AND NECk DISEASES
Implementation of ACE Inhibitor Regimen in Patients With Type 2 Diabetes Mellitus

The incidence of type 2 diabetes has proliferated and is associated with many problems, including chronic kidney disease. The purpose of this quality improvement project was to implement two evidence-based guidelines that may detect chronic kidney disease and slow its progression in patients with type 2 diabetes by implementing angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy according to evidence-based guidelines from the American Diabetes Association. Patients with type diabetes were screened for microalbuminuria and eGFR of < 60 mL/min/1.73 m2. Based on lab results, the provider recommended either an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker to patients with as appropriate. The primary aim of this project was to achieve 80% implementation of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker for patients with type 2 diabetes who met criteria. Second, seventy to 90 percent of early progression to chronic kidney disease among those with type 2 diabetes was to be identified via blood and urine testing. One hundred and sixty-three patients with type 2 diabetes were seen during the implementation phase and screened, and one hundred and thirty-two patients who needed an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker were placed on one or the other. Thirteen patients were on an angiotensinconverting enzyme inhibitor or an angiotensin receptor blocker prior to project implementation. Introducing an angiotensinconverting enzyme inhibitor or angiotensin receptor blocker as recommended for many patients with type 2 diabetes may slow the progression of chronic kidney disease and improve quality of life.
Effect of restrictive blood transfusion on postoperative acute kidney injury after total hip replacement arthroplasty: a prospective randomized controlled trial

This study was designed to evaluate the efficacy and safety of a restrictive transfusion strategy (transfusion threshold of hemoglobin 8 g/dL) compared to a conventional transfusion strategy (transfusion threshold of hemoglobin 10 g/dL) on postoperative AKI among patients undergoing total hip replacement arthroplasty (THRA). Patients undergoing THRA were divided into two groups: restrictive transfusion strategy (n=72) and conventional transfusion strategy (n=72). Stroke volume variation was performed to maintain methods, complications, and preoperative and postoperative laboratory tests. They were categorized according to changes in plasma creatinine (Cr) concentration within 48 hours after THRA using Acute Kidney Injury Network criteria. Acute kidney injury (AKI) occurred in three patients (4.2%) in the restrictive transfusion strategy group and two patients (2.8%) in the conventional transfusion strategy group (p=0.99). The mean serum Cr levels 48 hours after surgery were 0.76±0.36 and 0.66±0.20 mg/dL in the restrictive transfusion strategy group and the conventional transfusion strategy group, respectively (p=0.30). Perioperative restrictive transfusion or conventional transfusion in patients undergoing elective THRA is not related to AKI when maintaining proper volume status during surgery.
Effect of Warning Graphics Location on Driving Performance: An Eye Movement Study

ABSTRACT With the development of cutting-edge technology in the area of driving performance, driver warning systems based on head up displays (HUD) are considered to have the potential to improve driving safety in the future. The location of HUD warning graphics is a vital component to ensure that drivers obtain information the first time and avoid cognitive tunneling when coming across hazards; however, few studies have critically examined this. The present study investigated the advantages of HUD in presenting warning graphics in comparison with traditional head down display (HDD) in vehicles, and further explored the effect of HUD location based on comprehensive indicators, including behavior performance, eye movement data, and subjective assessment. The results revealed that compared with HDD, presenting warning graphics to drivers on HUD could significantly improve driving performance and eye movement patterns, and HUD was the preferential mode for drivers. Results also demonstrated that presenting HUD warning graphics at a location of 8°below the sight line was associated with the worst results in driving performance, eye movement patterns and subjective assessment. Other locations of HUD presentation were not associated with any significant differences for most indicators. These findings have some reference implications for automobile designers as they construct and implement HUD warning systems.
