Disordered Kondo Nanoclusters: Effect of Energy Spacing

Exact diagonalization results for Kondo nanoclusters alloyed with mixed valence impurities show that tuning the {\it energy spacing}, $\Delta$, drives the system from the Kondo to the RKKY regime. The interplay of $\Delta$ and disorder gives rise to a $\Delta$ versus concentration T=0 phase diagram very rich in structure, where regions with prevailing Kondo or RKKY correlations alternate with domains of ferromagnetic order. The local Kondo temperatures, $T_K$, and RKKY interactions depend strongly on the local environment and are overall {\it enhanced} by disorder, in contrast to the hypothesis of ``Kondo disorder'' single-impurity models.Comment: 4pages 4 figuresDisordered Kondo Nanoclusters: Effect of Energy Spacin

PreAdolescent CardioMetabolic Associations and Correlates : PACMAC : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in School of Sport and Exercise at Massey University, Wellington, New Zealand

Cardiovascular disease is typically associated with adults; however, atherosclerosis often initiates during preadolescence and has been linked to cardiometabolic risk factors. Preceding cardiometabolic risk factors include lifestyle factors: body fatness, physical fitness, physical [in]activity, sedentary behaviour, nutrition, and sleep. No known study has comprehensively assessed simultaneous associations among lifestyle factors with cardiometabolic risk factors in preadolescent children. A multicentred cross-sectional study design was utilised to investigate lifestyle factor associations with cardiometabolic risk factors in a sample of 392 children aged 8 to 10 years. Participants were recruited from primary schools located in the Wellington, Canterbury, and Otago regions in New Zealand. Data collection was carried out over 5 days between 09:00 a.m. and 12:00 p.m. at each location. The first objective assessed the associations among physical fitness, physical [in]activity, sedentary behaviour, nutrition, and sleep with body fatness indicators (body fat percentage, fat mass index, body mass index, and waist-to-hip ratio). Results indicated nutrition independently associated with body fat percentage (p < 0.05), whereas cardiorespiratory fitness significantly associated with all four body fatness indicators (p < 0.05). The second objective assessed the associations among body fatness, physical fitness, physical [in]activity, sedentary behaviour, nutrition, and sleep with cardiometabolic factors (blood pressure, cholesterol, vascular, and carbohydrate- metabolic). Results indicated body fat percentage associated with the blood pressure factor (p < 0.05); sedentary minutes, social jetlag, and Fruit and Vegetables pattern associated with the cholesterol factor (all p < 0.05); sedentary minutes and Processed Food pattern associated with the vascular factor (both p < 0.05); and cardiovascular fitness (V̇O₂max) and handgrip strength associated with the carbohydrate-metabolic factor (both p < 0.001). Accordingly, body fatness, physical fitness, nutrition, and sleep all associated with at least one cardiometabolic factor. Cardiorespiratory fitness associated with cardiometabolic health and was the key finding in Objective 1; therefore, physical fitness may be the most important lifestyle factor. However, as nutrition, sleep, sedentary behaviour, and body fatness also associated with cardiometabolic health, it appears one specific lifestyle factor does not entirely explain cardiometabolic health in preadolescent children, and thus a multimodal approach for health is required for this population

Problem Identification and Task Engagement Using the LIBRE Problem Solving Tool: A Case Study of Three Bilingual Teacher Candidates

Bilingual Latino students engage multiple languages, cultures and environments as they pursue educational and professional goals. For this underrepresented group, pursuing a post-secondary degree is a “lucha” (fight) to negotiate the complex interplay of historical, educational, and cultural variables and achieve academic success. Because Bilingual Latino teacher success is incumbent upon successfully negotiating and overcoming linguistic, cultural and educational challenges, examination of problem solving and goal setting is necessary to provide insight into the types of barriers and facilitators that this group experiences and the ways in which they overcome obstacles. An in-depth case study of three bilingual teacher candidates illustrates the use of the LIBRE problem-solving tool as a culturally responsive activity involving a sequence of problem identification, analysis, solution generation, and evaluation to facilitate problem resolution. The case studies examined herein illuminate self-reported social-cultural contextual challenges, solutions, goals, and engagement through explicit problem solving and shows the primacy of familia and cultura in these women’s lives, problem-solving, and decision making. Implications for teacher educators and bilingual Latino teacher candidates are discussed

The Influence of Family Business and Social Capital on Entrepreneurial Intentions among Female University Students in the Philippines

Purpose: Female entrepreneurs play a significant role in the socio-economic development process, particularly through job creation, innovation, leadership, and poverty alleviation in the Philippines yet the forces that drive their entrepreneurial intentions have received the least attention in recent studies. The present study unveils how social capital and family business influence the development of entrepreneurial intention among females using the case of undergraduate university students in the Philippines. Design/methodology/approach: Cross-sectional data were obtained from the total sample of 227 female undergraduates who participated in the study and a multivariate regression technique was employed for the data analysis. &nbsp;&nbsp; Findings: The findings unveil the significant role of bonding and linking social capital in the development of entrepreneurial intentions among female undergraduate students in the Philippines. The findings further suggest that female students whose families own businesses are more likely to form entrepreneurial intentions and behavior compared to their counterparts. Research limitations/implications: The findings from the study provide a new direction for entrepreneurship education and contribute to the theory and practice of female entrepreneurship. Originality/value: This paper is original Paper type: a Research Pape

A novel holistic design optimisation algorithm for the ironless inductive position sensor

The Ironless Inductive Position Sensor (I2PS) is a state-of-the-art high precision linear position sensor, which is designed to be radiation hard and immune to magnetic fields. This sensor is built for the Large Hadron Collider collimation system at the European Organization for Nuclear Research. It is continuously monitored to assess the precision, accuracy and drifts during the machine’s operation. The ironless inductive position sensor was previously designed and optimised manually on a programmed electromagnetic model and simulated using a finite element model simulator. This sensor has the potential to be used extensively in industry, especially in areas with high radiation and high electro-magnetic interference. To industrialise it, an automated design procedure is required that offers the possibility to a user with minimal knowledge to design and optimise the sensor. This paper identifies the optimisation parameters and constants required in the manual design. It hence presents an automated design procedure which uses a multi-objective optimisation algorithm to automatically produce ironless inductive position sensors tailor-made to the user’s specifications.peer-reviewe

Numerical Modeling of Synthetic Jets in Quiescent Air with Moving Boundary Conditions

Flow control is a key factor in optimizing the performance of any vehicle moving through fluids. Particularly, in aerodynamics there are many potential benefits for implementing synthetic jets to achieve aircraft designs with less moving parts, uper- maneuverability, and separation control for fuel economy. Piezoelectric synthetic jets are of special interest because of their lightweight and low power consumption. Numerous publications on such jets are available. Actuator properties and boundary conditions relevant to this particular application however are often overlooked. The focus of this project is to numerically model synthetic jets in quiescent air to study the influence of cavity geometry and boundary conditions of the piezoelectric diaphragm on jet velocity. Numerical simulation is performed for two synthetic jet cavities of different height and orifice diameter. The numerical modeling utilizes a turbulent RNG κ ε model and a moving boundary condition with two oscillating deflection profiles, parabolic and logarithmic, applied to the diaphragm. The actuators modeled are typical Bimorph and Thunder piezoelectric actuators. The initial conditions for the actuators are obtained experimentally resulting in 0.396mm and 0.07mm respectively when driven with a sinusoidal wave input at 1524 V/m and 4064 V/m. Although the velocity boundary numerical model gave overall better results than the current moving-boundary numerical model, the moving-boundary model is more accurate since it better approximates the movement of the diaphragm. From an optimizing viewpoint the moving boundary is more suitable to attempt to optimize the design because displacement magnitude of the diaphragm can be measured directly from experiments. For the higher displacement Bimorph actuator, a logarithmic profile matches the experimental results, whereas the parabolic profile provided better results for the relatively small displacement Thunder actuator. It is thus hypothesized that both tested actuators, Bimorph and Thunder, oscillate according to the specified logarithmic and parabolic profile respectively. Cavity height was briefly investigated for the Bimorph actuator. Results show that cavity height did not make a difference in the centerline velocity for the numerical model. The model fails to consider the important effect of the dynamic coupling of the actuator displacement and the pressure that develops inside the cavity. The pressure values obtained are comparable to the theoretical blocking pressure for the Bimorph in the cavity. The results of this study show that jet formation and development has unique characteristics for each actuator and cavity configuration. The smaller orifice cavity configuration produced a faster, longer, thinner jet with larger vortices than the bigger orifice. During max expulsion, t = 0.25T, and max ingestion, t = 0.75T, a low-pressure area localized at the corners of the orifice, inlet and exit respectively, were observed. All cavity configurations passed all three known jet formation criterions that include, Lo/Do\u3e1, Re \u3e 50, and Re/S2 \u3e 0.16

Implementation Strategies for Interventions Aiming to Increase Participation in Mail-Out Bowel Cancer Screening Programmes: A Realist Review

Background Bowel cancer is the third most commonly diagnosed cancer and the third most common cause of cancer-related death with 1,849,518 new cases of bowel diagnosed, and 880,792 deaths reported globally in 2018 alone. Survival can be improved through early detection via national mail-out bowel cancer screening programs; however, participation remains low in many countries. Behavior change is therefore required to increase participation. This realist review aims to (a) identify the behavior change techniques (BCTs) used in each intervention, (b) understand the mechanisms of action responsible for the BCTs effectiveness, and (c) apply a behavior change model to inform how behavior change techniques and mechanisms of action (MoA) can be combined to increase screening participation. Methods We systematically reviewed the literature for interventions aiming to increase participation in mail-out bowel cancer screening. We used a four-stage realist synthesis approach whereby; (1) interventions were extracted from each study; (2) BCTs applied in each intervention were identified and coded using the BCT taxonomy-v1; (3) the Theory and Techniques tool was used to link BCT to their mechanisms of action; and (4) BCT and MoA were categorized according to their effectiveness and what Health Action Process Approach (HAPA) stage of change they would affect. Results We identified 68 intervention trials using 26 unique BCTs and 13 MoA to increase participation. Sixteen BCTs and 10 MoA were identified within the interventions that successfully increased participation rates. Interventions targeting both stages of the HAPA model had a higher success rate (80%) than those targeting one stage of change (51%). When targeting only one stage, interventions targeting the volitional stage had a higher success rate (71%) than interventions only targeting the motivational stage of change (26%). Conclusion Importantly, this review identified a suite of BCTs and MoA that are effective for increasing participation in mail-out bowel cancer screening programs. With increased participation in bowel cancer screening leading to improved survival, our findings are key to informing the improvement of policy and interventions that aim to increase screening using specific strategies at key stages of health decision-making

Neutron-Capture elements in planetary nebulae: first detections of near-Infrared [Te III] and [Br V] emission lines

We have identified two new near-infrared emission lines in the spectra of planetary nebulae (PNe) arising from heavy elements produced by neutron capture reactions: [Te III] 2.1019 $\mu$m and [Br V] 1.6429 $\mu$m. [Te III] was detected in both NGC 7027 and IC 418, while [Br V] was seen in NGC 7027. The observations were obtained with the medium-resolution spectrograph EMIR on the 10.4m Gran Telescopio Canarias at La Palma, and with the high-resolution spectrograph IGRINS on the 2.7m Harlan J. Smith telescope at McDonald Observatory. New calculations of atomic data for these ions, specifically A-values and collision strengths, are presented and used to derive ionic abundances of Te$^{2+}$ and Br$^{4+}$. We also derive ionic abundances of other neutron-capture elements detected in the near-infrared spectra, and estimate total elemental abundances of Se, Br, Kr, Rb, and Te after correcting for unobserved ions. Comparison of our derived enrichments to theoretical predictions from AGB evolutionary models shows reasonable agreement for solar metallicity progenitor stars of $\sim$2 - 4 M$_{\odot}$. The spectrally-isolated [Br V] 1.6429 $\mu$m line has advantages for determining nebular Br abundances over optical [Br III] emission lines that can be blended with other features. Finally, measurements of Te are of special interest because this element lies beyond the first peak of the s-process, and thus provides new leverage on the abundance pattern of trans-iron species produced by AGB stars.Comment: 9 pages, 1 figure, 4 tables.

DolphinAtack: Inaudible Voice Commands

Speech recognition (SR) systems such as Siri or Google Now have become an increasingly popular human-computer interaction method, and have turned various systems into voice controllable systems(VCS). Prior work on attacking VCS shows that the hidden voice commands that are incomprehensible to people can control the systems. Hidden voice commands, though hidden, are nonetheless audible. In this work, we design a completely inaudible attack, DolphinAttack, that modulates voice commands on ultrasonic carriers (e.g., f > 20 kHz) to achieve inaudibility. By leveraging the nonlinearity of the microphone circuits, the modulated low frequency audio commands can be successfully demodulated, recovered, and more importantly interpreted by the speech recognition systems. We validate DolphinAttack on popular speech recognition systems, including Siri, Google Now, Samsung S Voice, Huawei HiVoice, Cortana and Alexa. By injecting a sequence of inaudible voice commands, we show a few proof-of-concept attacks, which include activating Siri to initiate a FaceTime call on iPhone, activating Google Now to switch the phone to the airplane mode, and even manipulating the navigation system in an Audi automobile. We propose hardware and software defense solutions. We validate that it is feasible to detect DolphinAttack by classifying the audios using supported vector machine (SVM), and suggest to re-design voice controllable systems to be resilient to inaudible voice command attacks.Comment: 15 pages, 17 figure
