AFM Cantilever Design for Multimode Q Control: Arbitrary Placement of Higher Order Modes

In the fast growing field of multifrequency atomic force microscopy (AFM), the benefits of using higher order modes have been extensively reported on. However, higher modes of AFM cantilevers are difficult to instrument and Q control is challenging owing to their high-frequency nature. At these high frequencies, the latencies in the computations and analog conversions of digital signal processing platforms become significant and limit the effective bandwidth of digital feedback controller implementations. To address this issue, this article presents a novel cantilever design for which the first five modes are placed within a 200-kHz bandwidth. The proposed cantilever is designed using a structural optimization routine. The close spacing and low mechanical bandwidth of the resulting cantilever allows for the implementation of Q controllers for all five modes using a standard field programmable gate array (FPGA) development board for bimodal AFM and imaging on higher order modes.
Prevalence and Risk Factors of Genital Diseases of Goats and Ewes in the far North Region of Cameroon

This study was carried out at the municipal slaughterhouse of Maroua (FarNorth Cameroon), in order to determine the prevalence and risk factors of the pathologies of the genitals organs of local goats and ewes. A total of 631 genital tracts were examined, including 448 and 183 for goats and ewes, respectively. Before slaughter, the animals were characterized (breed, age, weight and Body Condition Score (BCS)). After slaughter, the entire genital tract of each female was carefully examined for morphological or pathological abnormalities. The ovaries of each animal were also sampled to determine the follicular population and ovarian pathologies. The results indicated that means age (years), weight (kg) and BCS of females were 2.59 ± 1.49, 23.00 ± 2.19 and 2.74 ± 0.63, respectively. The mean follicular population was 9.96 ± 9.63 per ovary with 10.38 ± 5.48 and 9.03 ± 5.02, respectively, for the goat and ewe (p = 0.00). A pregnancy rate of 45.3% was observed. The overall prevalence of genital abnormalities was 36.3% with 38.20% and 31.70% respectively in goats and ewes (p = 0.10). The most common pathologies of the ovary were ovarian cysts (9.19%), oophoritis (4.28%), ovarian hypoplasias (3.96%); those in the uterus included metritis (6.81%), Cysticercus tenuicollis (3.65%) and the affections of the vagina and vulva were more represented by Cysticercus tenuicollis (3.32%). Non-pregnant and thin (BCS = 1-2) females at least 2 years old and raised in the dry season were the most affected (P <0.05).
Niche Complementarity and Resistance to Grazing Promote the Invasion Success of Sargassum horneri in North America

Invasive species are a growing threat to conservation in marine ecosystems, yet we lack a predictive understanding of ecological factors that influence the invasiveness of exotic marine species. We used surveys and manipulative experiments to investigate how an exotic seaweed, Sargassum horneri, interacts with native macroalgae and herbivores off the coast of California. We asked whether the invasion (i.e., the process by which an exotic species exhibits rapid population growth and spread in the novel environment) of S. horneri is influenced by three mechanisms known to affect the invasion of exotic plants on land: competition, niche complementarity and herbivory. We found that the removal of S. horneri over 3.5 years from experimental plots had little effect on the biomass or taxonomic richness of the native algal community. Differences between removal treatments were apparent only in spring at the end of the experiment when S. horneri biomass was substantially higher than in previous sampling periods. Surveys across a depth range of 0–30 m revealed inverse patterns in the biomass of S. horneri and native subcanopy-forming macroalgae, with S. horneri peaking at intermediate depths (5–20 m) while the aggregated biomass of native species was greatest at shallow (<5 m) and deeper (>20 m) depths. The biomass of S. horneri and native algae also displayed different seasonal trends, and removal of S. horneri from experimental plots indicated the seasonality of native algae was largely unaffected by fluctuations in S. horneri. Results from grazing assays and surveys showed that native herbivores favor native kelp over Sargassum as a food source, suggesting that reduced palatability may help promote the invasion of S. horneri. The complementary life histories of S. horneri and native algae suggest that competition between them is generally weak, and that niche complementarity and resistance to grazing are more important in promoting the invasion success of S. horneri.
Exploring Employee Experiences of Distributed Leadership in Consultancy SMEs

 Abstract— Despite a growth in literature on distributed leadership, the majority of studies are centred on large public organisations particularly within the health and education sectors. The purpose of this study is to fill the gap in the literature by exploring employee experiences of distributed leadership within two commercial consultancy SME businesses in the UK and USA. The aim of the study informed an exploratory method of research to gather qualitative data drawn from semi-structured interviews involving a sample of employees in each organisation. A series of broad, open questions were used to explore the employees’ experiences; evidence of distributed leadership; and extant barriers and practices in each organisation. Whilst some of our findings aligned with patterns and practices in the existing literature, it importantly discovered some emergent themes that have not previously been recognised in the previous studies. Our investigation identified that whilst distributed leadership was in evidence in both organisations, the interviewees’ experience reported that it was sporadic and inconsistent. Moreover, non-client focused projects were reported to be less important and distributed leadership was found to be inconsistent or non-existent.
The Spatial Resolution Enhancement of FY-4 Satellite MMSI Beam Scanning Measurements

The deconvolution technique can improve the spatial resolution of Millimeter and Sub-millimeter Sounding/Imager (MMSI) of FY-4 satellite. In this paper, the technique is applied to the simulated brightness temperature image of a typhoon scene, which indicates that the deconvolution technique is feasible to enhance the spatial resolution of MMSI. In the analysis of the antenna temperature of the earth obtained by MMSI, We consider the effect of beam scanning and acquire an accurate estimate of the brightness temperature distribution. The results show that the outline of the typhoon in the enhanced image is closer to the initial image than the non-enhanced image. The correlation coefficient is improved and the spatial resolution is enhanced from 96km to 57km, which indicates the effectiveness.

Identify Key Success Factors Using Interpretive Structural Modeling (ISM) : A Case Study in Small and Medium Enterprise in Indonesia

Small Medium Enterprises (SMEs) have a very significant role in the economy of the community. The large number of SMEs on the same field causes high competition to survive in market. A lot of literature empirically discuss the success factors of SMEs in Indonesia, but there are still few which carry out further research by structuring a model of interconnectedness between these elements to find out the key factors. This study aims to determine the key factors by classifying and structurally modelling the factors based on the level of the affecting elements of an SME’s success. Interpretive Structural Modeling (ISM), which is an interactive learning process where a set of elements are structured into a comprehensive system model, is used as the approach. ISM helps in determining the sequence and purpose of complex relationships between elements in the system. This research found 24 success factors that divided into 13 levels and categorized into 4 sectors including autonomous, dependent, linkage, and independent sector. The sub-elements or key factors that influence the success of SMEs include (1) motivation and experience, (2) entrepreneurial spirit and leadership, (3) formal education level, and (4) technical guidance.
A Tri-band Low-noise Cryogenic Receiver for Geodetic VLBI Observations with VGOS Radio Telescopes

This paper shows the development of a simultaneous tri-band (S: 2.2 2.7 GHz, X: 7.5 9 GHz and Ka: 28 33 GHz) low-noise cryogenic receiver for geodetic Very Long Baseline Interferometry (geo-VLBI) which has been developed by the technical staff of Yebes Observatory laboratories in Spain. The receiver was installed in the first radio telescope of the Red Atlántica de Estaciones Geodinámicas y Espaciales (RAEGE) project, which is located in Yebes Observatory, in the frame of the VLBI Global Observing System (VGOS). After this, the receiver was borrowed by the Norwegian Mapping Autorithy (NMA) for the commissioning of two VGOS radiotelescopes in Svalbard (Norway). A second identical receiver was built for the Ishioka VGOS station of the Geospatial Information Authority (GSI) of Japan, and a third one for the second RAEGE VGOS station, located in Santa María (Açores Archipelago, Portugal). The average receiver noise temperatures are 21, 23 and 25 Kelvin and the measured antenna efficiencies are 70%, 75% and 60% in S-band, X-band and Ka-band, respectively.
Collective spin waves in arrays of asymmetric and symmetric width nanowires: effect of the film layering sequence

We have studied, experimentally and theoretically, the effect of a layering sequence on the magnonic band structure in dense arrays of both asymmetric- and symmetric cross-section tri-layered Py/Cu/Fe and Fe/Cu/Py nanowires. The spin-wave dispersion for these artificial crystals has been measured with Brillouin light scattering (BLS) spectroscopy. We also carried out numerical simulations of the dispersion using an original model employing a 2D Green’s function description of the dynamic dipole field of the precessing magnetization. The presence of the Cu spacer exchange-decouples the two magnetic layers, which stabilizes two equilibrium states of static magnetization. These are the parallel and antiparallel states, for which the static magnetization vectors for the layers are either co-aligned or anti-aligned to each other, respectively. These states are stable in a range of applied fields that depend on the layer width and their ordering in the stack. The magnetization configurations and layers sequence, as well as the presence of acoustic (in-phase) and optic (out-of-phase) spin-wave modes, have a significant impact on the magnonic band structure both in terms of the frequency positions of the dispersive and stationary modes and on their spatial profiles.
Theoretical basis of optimal therapy for individual patients in chronic myeloid leukemia : A mathematical approach

Abstract Even if the successful pharmacological therapy for chronic myeloid leukemia has reached today a near normal life expectancy in a patient diagnosed with this malignancy, almost one in four patients will change the line of tyrosin-kinase inhibitors during therapy, may it be due to poor response of due to intolerance to therapy. In this paper, starting from a mathematical characterization of the chronic phase in myeloid leukemia, a theoretical investigation of optimal therapy is undertaken as base for further pharmaceutical research and personalized treatment protocols.
THE SYNERGISTIC EFFECTS OF DRIP SYSTEM UNIFORMITY AND SOIL VARIABILITY ON DRAINAGE AND NITRATE LEACHING UNDER ARID CONDITIONS: A NUMERICAL STUDY

Both irrigation and soil heterogeneities can affect drainage and nitrate leaching. However, the interactive effect of irrigation and soil heterogeneity under different irrigation levels still remains unclear. The irrigation and soil heterogeneity effects on drainage and nitrate leaching at a typical growth stage for cotton were evaluated using the HYDRUS‐2D software. The results showed that increasing irrigation heterogeneity increased the average drainage and nitrate leaching; however, the opposite result was observed for the effect of soil heterogeneity. Both irrigation and soil heterogeneity had a negative effect on the Nemerow average drainage and nitrate leaching. The Nemerow average drainage and nitrate leaching that resulted from the combined heterogeneities were higher than those obtained when either irrigation or soil heterogeneity was considered. An increase in irrigation level increased the Nemerow average drainage and nitrate leaching. Both irrigation and soil heterogeneity had a substantial influence on the variability of drainage and nitrate leaching. Combined irrigation and soil heterogeneities resulted in a synergistic effect on the variability in nitrate leaching. An increase in irrigation level did not alleviate the negative effects of irrigation and soil heterogeneities on variability in nitrate leaching. A low drip system uniformity of 60% is not recommended because of the substantially increased risk of nitrate leaching in arid regions. © 2019 John Wiley & Sons, Ltd.
Triadic Human-Robot Interaction. Distributed Agency and Memory in Robot Assisted Interactions

We argue that the field of human-robot interaction needs a distributed and socially situated understanding of reminding and scheduling practices in the design of robots to meet the needs of people with cognitive disabilities. The results are based on an interaction analysis of video recorded workshop interactions during a co-creation process in which the participants tested a reminder-robot prototype that was designed for and with people with acquired brain injury.
Selection of optimized features for fusion of palm print and finger knuckle‐based person authentication

The impact of digital technology in biometrics is much more efficient at interpreting data than humans, which results in completely replacement of manual identification procedures in forensic science. Because the single modality‐based biometric frameworks limit performance in terms of accuracy and anti‐spoofing capabilities due to the presence of low quality data, therefore, information fusion of more than one biometric characteristic in pursuit of high recognition results can be beneficial. In this article, we present a multimodal biometric system based on information fusion of palm print and finger knuckle traits, which are least associated to any criminal investigation as evidence yet. The proposed multimodal biometric system might be useful to identify the suspects in case of physical beating or kidnapping and establish supportive scientific evidences, when no fingerprint or face information is present in photographs. The first step in our work is data preprocessing, in which region of interest of palm and finger knuckle images have been extracted. To minimize nonuniform illumination effects, we first normalize the detected circular palm or finger knuckle and then apply line ordinal pattern (LOP)‐based encoding scheme for texture enrichment. The nondecimated quaternion wavelet provides denser feature representation at multiple scales and orientations when extracted over proposed LOP encoding and increases the discrimination power of line and ridge features. To best of our knowledge, this first attempt is a combination of backtracking search algorithm and 2D2LDA has been employed to select the dominant palm and knuckle features for classification. The classifiers output for two modalities are combined at unsupervised rank level fusion rule through Borda count method, which shows an increase in performance in terms of recognition and verification, that is, 100% (correct recognition rate), 0.26% (equal error rate), 3.52 (discriminative index), and 1,262 m (speed).
Formal specification, monitoring, and verification of autonomous vehicles in Isabelle/HOL (Formale Spezifikation, Erfüllbarkeitsanalyse, und formale Verifikation von autonomen Fahrzeugen in Isabelle/HOL)

This thesis combines three formal verification techniques — theorem proving, satisfiability checking (runtime monitoring), and reachability analysis — for formally analysing autonomous vehicles. First, we formalise the required elements which will be the foundation for formally analysing autonomous vehicles. Next, we formalise a collection of selected traffic rules from the German traffic code (Strasenverkhersordnung) and propose a method to monitor them formally. Lastly, we demonstrate how to use reachability analysis to formally construct a manoeuvre automaton which can be used for motion planning of autonomous vehicles.
Challenges to children’s rights: Experiences from Ethiopia

In Ethiopia, there have been significant legislative frameworks in order to protect the rights of children and reduce their vulnerability. However, many of the relevant child right instruments have not yet been implemented to a satisfying degree. The aim of this article is to understand the challenges that impede the effectiveness of child rights system from children’s perspective. The empirical data upon which the author draws was gathered through repeated periods of qualitative fieldwork carried out in 2014/2015 with 24 children in the town of Dilla in Gedeo, southern Ethiopia. Parents, legal experts, police officers, and social workers also participated in the study. The author used informal dialogue, in-depth interviews, and focus group discussions to obtain the empirical data. This study has also benefited from various secondary sources. As the study shows, negative social construct of children, culturally embedded decisions and practices, poverty and deprivation, gaps in legislative frameworks, lack of resources, coordination, and commitment among responsible actors are identified as major challenges that impede the enforcement of child rights system. Thus, it is necessary to adopt holistic approach and deal with the broader structural and social barriers that denied children what they deserve in so many ways.

Factors that Influence Effective Veteran Teachers' Decisions to Remain in High-Poverty Elementary Schools.

KEARNEY, DIANN PICKARD. Factors that Influence Effective Veteran Teachers’ Decisions to Remain in High-Poverty Elementary Schools. (Under the direction of Bonnie Fusarelli and Matt Militello, Co-Chairs.) The purpose of this expository case study is to determine what factors influence the decisions of effective veteran teachers to remain in high-poverty elementary schools in an urban school district. I wanted to explore why, given the high rate of growth and the high attrition rate in this school system, like other urban districts, effective veteran teachers identified stay at these more challenging schools. This study sought to identify the contributing factors and explore these factors as they relate to educational leaders who focus on teacher retention. Data gathered through interviews with the principals and 15 teachers of three high-poverty elementary schools indicate that school systems and principals should implement buildingand system-level changes to better retain effective veteran teachers at high-poverty schools.
