description: Ellipsometry is a technique whereby the measurement of the two orthogonal polarization components of light reflected at glancing incidence allows a characterization of the optical properties of a material at a particular frequency. Importantly, it obviates the need for measurement against a standard reference sample, and so can provide reliable spectroscopic information even when surface morphology is unknown, of marginal quality and/or a reference is unavailable. Although a standard technique in the visible range, it has not been widely applied in the Terahertz (THz) spectral range despite its potential utility. This is largely because of the technical difficulties that these frequencies present. This review details recent progress in the implementation of THz range ellipsometry. We discuss a variety of configurations including various kinds of laboratory and facility based sources using both continuous wave and pulsed spectroscopic methods. We discuss the general problems encountered when trying to import the methodologies of visible range ellipsometry to the THz range and give examples of where the technique has been successful thus far.

description: Existing prosthetic technologies for people with upper limb amputation are being adopted at moderate rates. Once fitted for these devices, many upper limb amputees report not using them regularly or at all. The primary aim of this study was to solicit feedback about prosthetic technology and important device design criteria from amputees, clinicians, and device regulators. We compare these perspectives to identify common or divergent priorities. Twenty-one adults with upper limb loss, 35 clinicians, and 3 regulators completed a survey on existing prosthetic technologies and a conceptual sensorimotor prosthesis driven by implanted myoelectric electrodes with sensory feedback via spinal root stimulation. The survey included questions from the Trinity Amputation and Prosthesis Experience Scale, the Disabilities of the Arm, Shoulder, and Hand, and novel questions about technology acceptance and neuroprosthetic design. User and clinician ratings of satisfaction with existing devices were similar. Amputees were most accepting of the proposed sensorimotor prosthesis (75.5% vs clinicians (68.8%), regulators (67.8%)). Stakeholders valued user-centered outcomes like individualized task goals, improved quality of life, device reliability, and user safety; regulators emphasized these last two. The results of this study provide insight into amputee, clinician, and regulator priorities to inform future upper-limb prosthetic design and clinical trial protocol development.
Measuring Urbanity One Block at a Time: The Neighborhood Transit Readiness Scorecard

description: This paper outlines a methodology that assesses urbanity in three dimensions (density, diversity, and design) and creates a combined scorecard that weights each dimension according to its influence on transit usage and walkability. Using no proprietary methods, this approach can be repeated by any individual or local government with GIS software and basic internet access. The resulting measurements can be used by communities to assess what types of investments and regulatory changes are necessary to create more transitand pedestrian-friendly communities.

description: We report on an all-sky search for periodic gravitational waves in the frequency band 50–800 Hz and with the frequency time derivative in the range of 0 through −6×10−9 Hz/s. Such a signal could be produced by a nearby spinning and slightly nonaxisymmetric isolated neutron star in our Galaxy. After recent improvements in the search program that yielded a 10× increase in computational efficiency, we have searched in two years of data collected during LIGO’s fifth science run and have obtained the most sensitive all-sky upper limits on gravitational-wave strain to date. Near 150 Hz our upper limit on worst-case linearly polarized strain amplitude h0 is 1×10−24, while at the high end of our frequency range we achieve a worst-case upper limit of 3.8×10−24 for all polarizations and sky locations. These results constitute a factor of 2 improvement upon previously published data. A new detection pipeline utilizing a loosely coherent algorithm was able to follow up weaker outliers, increasing the volume of space where signals can be detected by a factor of 10, but has not revealed any gravitational-wave signals. The pipeline has been tested for robustness with respect to deviations from the model of an isolated neutron star, such as caused by a low-mass or long-period binary companion. © 2012 The American Physical Society

description: Experiments were conducted on the flow through a transonic turbine cascade. Secondary flows and a wide range of vortex types were encountered, including horseshoe vortices, shock-induced passage vortices, and streamwise vortices on the suction surface. In the separation region on the suction surface, a large rollup of passage vorticity occurred. The blunt leading edge gave rise to strong horseshoe vortices and secondary flows. The suction surface had a strong convex curvature over the forward portion and was quite flat further downstream. Surface flow visualization was performed and this convex surface displayed coherent streamwise vorticity. At subsonic speeds, strong von Ka ́rma ́n vortex shedding resulted in a substantial base pressure deficit. For these conditions, time- resolved measurements were made of the Eckert-Weise energy separation in the blade wake. At transonic speeds, exotic shedding modes were observed. These phenomena all occurred in experiments on the flow around one particular turbine nozzle vane in a linear cascade.

description: We present the first Open Gravitational-wave Catalog, obtained by using the public data from Advanced LIGO's first observing run to search for compact-object binary mergers. Our analysis is based on new methods that improve the separation between signals and noise in matched-filter searches for gravitational waves from the merger of compact objects. The three most significant signals in our catalog correspond to the binary black hole mergers GW150914, GW151226, and LVT151012. We assume a common population of binary black holes for these three signals by defining a region of parameter space that is consistent with these events. Under this assumption, we find that LVT151012 has a 97.6% probability of being astrophysical in origin. No other significant binary black hole candidates are found, nor did we observe any significant binary neutron star or neutron star-black hole candidates. We make available our complete catalog of events, including the subthreshold population of candidates.

description: The numbers of the botnet attacks are increasing day by day and the detection of botnet spreading in the network has become very challenging. Bots are having specific characteristics in comparison of normal malware as they are controlled by the remote master server and usually dont show their behavior like normal malware until they dont receive any command from their master server. Most of time bot malware are inactive, hence it is very difficult to detect. Further the detection or tracking of the network of theses bots requires an infrastructure that should be able to collect the data from a diverse range of data sources and correlate the data to bring the bigger picture in view. In this paper, we are sharing our experience of botnet detection in the private network as well as in public zone by deploying the nepenthes honeypots. The automated framework for malware collection using nepenthes and analysis using anti-virus scan are discussed. The experimental results of botnet detection by enabling nepenthes honeypots in network are shown. Also we saw that existing known bots in our network can be detected.

description: Suppose that a Lie algebra $L$ admits a finite Frobenius group of automorphisms $FH$ with cyclic kernel $F$ and complement $H$ such that the characteristic of the ground field does not divide $|H|$. It is proved that if the subalgebra $C_L(F)$ of fixed points of the kernel has finite dimension $m$ and the subalgebra $C_L(H)$ of fixed points of the complement is nilpotent of class $c$, then $L$ has a nilpotent subalgebra of finite codimension bounded in terms of $m$, $c$, $|H|$, and $|F|$ whose nilpotency class is bounded in terms of only $|H|$ and $c$. Examples show that the condition of the kernel $F$ being cyclic is essential.

description: Community-based strategic planning is gaining wide acceptance in North Carolina. Communities large and small have used strategic planning principles to set priorities, focus their efforts and mobilize resources for community and economic development. The Regional Economic Strategy Project (RESP), undertaken by Western Carolina University's Center for Improving Mountain Living, applied strategic planning methods in an effort to stimulate regional economic development in seventeen western North Carolina counties. The project received a 1989 Project of the Year award from the National Association of Management and Technical Assistance Centers (NAMTAC). In 1990, it won a second NAMTAC Project of the Year award for applied research conducted under the project's Business Capital Task Force. A third NAMTAC Project of the Year award was announced in 1992 for the Mountain Commercial Lending Consortium, an initiative that grew out of the RESP. In a report to the Organization for Economic Cooperation and Development, the Corporation for Enterprize Development (CFED) cited the Regional Economic Strategy Project as an example of what CFED has called the new paradigm, or Third Wave, of economic development policy.

description: We report on a Kondo correlated quantum dot connected to two-dimensional leads where we demonstrate the renormalization of the g factor in the pure Zeeman case. i.e., for magnetic fields parallel to the plane of the quantum dot. For the same system, we study the influence of orbital effects by investigating the quantum Hall regime; i.e., a perpendicular magnetic field is applied. In this case an unusual behavior of the suppression of the Kondo effect and of the split zero-bias anomaly is observed. The splitting decreases with magnetic field and shows discontinuous changes that are attributed to the intricate interplay between Kondo screening and the quantum Hall edge structure originating from electrostatic screening. This edge structure, made up of compressible and incompressible stripes, strongly affects the Kondo temperature of the quantum dot and thereby influences the renormalized g factor. © 2016 American Physical Society.
Social and Individual Learning in the Fall Field Cricket

description: Social learning is a well-studied process in vertebrates, yet insect social learning studies have historically neglected solitary insects. To bridge this gap, I investigated whether the fall field cricket, Gryllus pennsylvanicus, could use individual and social learning to associate water with visual and odour cues. Demonstrator crickets had firsthand experience sampling water paired with cues, and observer crickets watched the demonstrators. I therefore tested demonstrators for individual learning and observers for social learning. I tested for learning by measuring cue preference in the absence of water. When quantifying cue preference by the proportion of time spent near rewarded cues, there was no evidence of individual or social learning. However, when quantifying cue preference by the first cue investigation (>3 seconds) during the test, crickets showed evidence of individual but not social learning. There was also a small effect of cue type on learning. These results differ from previous studies that found social learning in other species of crickets. The findings highlight that there are interspecific differences in learning and social behaviour, and that the method of quantifying learning can influence the outcome.

Space group symmetry, spin-orbit coupling and the low energy effective Hamiltonian for iron based superconductors

description: We construct the symmetry adapted low energy effective Hamiltonian for the electronic states in the vicinity of the Fermi level in iron based superconductors. We use Luttinger's method of invariants, expanding about Gamma and M points in the Brillouin zone corresponding to two iron unit cell, and then matching the coefficients of the expansion to the 5- and 8-band models. We then use the method of invariants to study the effects of the spin-density wave order parameters on the electronic spectrum, with and without spin-orbit coupling included. Among the results of this analysis is the finding that the nodal spin-density wave is unstable once spin-orbit coupling is included. Similar analysis is performed for the A_{1g} spin singlet superconducting state. Without spin-orbit coupling there is one pairing invariant near the Gamma point, but two near the M point. This leads to an isotropic spectral gap at the hole Fermi surface near Gamma, but anisotropic near M. The relative values of these three parameters determine whether the superconducting state is s_{++}, s_{+-}, or nodal. Inclusion of spin-orbit coupling leads to additional mixing of spin triplet pairing, with one additional pairing parameter near Gamma and one near M. This leads to an anisotropic spectral gap near both hole and electron Fermi surfaces, the latter no longer cross, but rather split.

Relational Flow in Improvisational Tap Dancing: A Phenomenological Study

description: This motion-sensing phenomenological inquiry explores relational flow moments experienced by five professional tap dance artists in improvisational inter-action with jazz musicians to better understand the meaning of feeling relational flows in inter-activities. Guided through the Function-to-Flow conceptual framework, interviews and study with the five research participants focused on the functional capacities required to feel relational flows (e.g. movement repertoire and listening being), the form and structures of feeling relational flows (e.g. visible, audible, animatable and tangible forms of relational flows), and the feelings of relational flow experiences (e.g. connecting to, disconnecting from and transcending the self, Other and spiritual world) to discern meaning from inter-active, improvisational jazz-tap experiences. A motion-sensing phenomenological approach, which combines Max van Manen's hermeneutics with Michel Henry's material phenomenology of life to turn not simply to the things themselves but to the how of their appearing - that is, to the affective resonances of living, of bodily being - enables a primacy of sensorial attunement to the affects of kinaesthetic being or the feelings of being a body in motion. Interviews with the participants reveal meanings of relational flow in improvisational tap dance practices, and align with Maxine Sheets-Johnstone's call to phenomenologically inquire into the extraordinary experiential movement realities of professional dancers to deepen our understanding of the effect of their honed kinetic capacities. This inquiry seeks to not only deepen our knowledge of relational flow experiences, but also to add to research on tap dance, improvisational practice, and dance education more broadly.

We observe no depolarization of the supercontinuum, and no spatial dependence of polarization ratios for any wavelength. We discuss the discrepancy of YAG’s polarization behavior in the context of well-established results in literature reporting self-induced depolarization in other cubic crystals. © 2018, The Author(s).

description: We present the design, construction, and characterization of a multichannel, low-drift, low-noise dc voltage source specially designed for biasing the electrodes of segmented linear Paul traps. The system produces 20 output voltage pairs having a common-mode range of 0 to +120 V with 3.7 mV/LSB (least significant bit) resolution and differential ranges of ±5 V with 150 μV/LSB or ±16 V with 610 μV/LSB resolution. All common-mode and differential voltages are independently controllable, and all pairs share the same ground reference. The measured drift of the voltages after warm-up is lower than 1 LSB peak-to-peak on the time scale of 2 h. The noise of an output voltage measured with respect to ground is <10 μVRMS within 10 Hz-100 kHz, with spectral density lower than 3 nV Hz−1/2 above 50 kHz. The performance of the system is limited by the external commercial multichannel DAC unit NI 9264, and in principle, it is possible to achieve higher stability and lower noise with the same voltage ranges. The system has a compact, modular, and scalable architecture, having all parts except for the DAC chassis housed within a single 19 3HE rack.

description: This paper is mainly a summary of two years of my research. I will start from the basic theory of the book and continue to the latest research. My first year of research was evaluating the performance of hybrid MPI programming. The second year is to design a better parallel computing model. I analyzed all the papers published so far on MPI hybrid programming, the LogP model, the LogGP model and their variants. Gain a better understanding of the history, hotspots and difficulties of research in this field. I also sorted out the theory and hardware aspects of the entire parallel computing. Know why the computer develops like this, and what is the bottleneck of development. Lay the foundation for the introduction of the following research. In terms of MPI fine-grained hybrid programming, I have conducted some experiments on supercomputing systems and found that the performance of MPI fine-grained is not necessarily faster, which is contrary to the opinions of some papers. I also compared the performance of OpenMP and Pthread in certain scenarios and found that OpenMP runs faster, although Pthread is a more low-level operation. I summarize all variants of LogP and LogGP, and based on my experiments, propose two parameters that should be considered for fine-grained lock contention problems.

description: SCUBA-2 is an innovative 10000 pixel bolometer camera operating at submillimetre wavelengths on the James Clerk Maxwell Telescope (JCMT). The camera has the capability to carry out wide-field surveys to unprecedented depths, addressing key questions relating to the origins of galaxies, stars and planets. With two imaging arrays working simultaneously in the atmospheric windows at 450 and 850 microns, the vast increase in pixel count means that SCUBA-2 maps the sky 100-150 times faster than the previous SCUBA instrument. In this paper we present an overview of the instrument, discuss the physical characteristics of the superconducting detector arrays, outline the observing modes and data acquisition, and present the early performance figures on the telescope. We also showcase the capabilities of the instrument via some early examples of the science SCUBA-2 has already undertaken. In February 2012, SCUBA-2 began a series of unique legacy surveys for the JCMT community. These surveys will take 2.5 years and the results are already providing complementary data to the shorter wavelength, shallower, larger-area surveys from Herschel. The SCUBA-2 surveys will also provide a wealth of information for further study with new facilities such as ALMA, and future telescopes such as CCAT and SPICA.

description: Transport measurements were performed on the organic layered compound \aI3 under hydrostatic pressure. The carrier types, densities and mobilities are determined from the magneto-conductance of \aI3 . While evidence of high-mobility massless Dirac carriers has already been given, we report here, their coexistence with low-mobility massive holes. This coexistence seems robust as it has been found up to the highest studied pressure. Our results are in agreement with recent DFT calculations of the band structure of this system under hydrostatic pressure. A comparison with graphene Dirac carriers has also been done.

Raleigh's Neighborhood Planning Program and Conservation Zoning Districts

description: As we enter the next century, older neighborhoods are increasingly under influences that can alter their fundamental nature. Traffic and parking problems, infill pressures, changes in land use, turnover from home-ownership to rental, can all contribute to neighborhood evolution and even decline. Unfortunately, neighborhoods seldom have the opportunity to plan pro-actively for their futures; rather, contentious and emotional responses to particular, well-defined "threats'" are the norm. Long-term trends go unconsidered and no policy direction is set. In addition, tools for neighborhood stabilization tend to be very limited. Although many communities have neighborhood planning programs, there are only a handful of cities across the country that have developed neighborhood conservation overlay zoning districts. Raleigh's program is unique in that the particulars of each conservation district are determined through a rigorous, neighborhood participation-oriented planning process. The conservation district permits an unusual level of neighborhood self-determinism about its own zoning. It can also provide a means for neighborhood stabilization similar to local historic district zoning but less intrusive. Raleigh historically has been reliant on state government, North Carolina State University, and other institutions for a large share of its economy. Development of Research Triangle Park in the 1 950s shifted the area from blue-collar to white-collar jobs. The neighborhoods produced by these socioeconomic conditions tended to be quite stable. Several of the oldest neighborhoods, which are within walking distance of downtown, have survived urban renewal to become picturesque historic areas. Many middle-class suburbs with large wooded lots were developed surprisingly close to downtown ("inside the Beltline") through the 1950s and 1960s. In their quiet way, these neighborhoods are at the heart of the identity and desirability of Raleigh. The City has grown at a steady, modest rate since its founding in the 18th century. By the mid-1980s, however, Raleigh was one of the fastest growing American cities. Infill development became quite common all over the City, and some of the older neighborhoods were subject to new development pressures. Two typical types of infill problems occurred during the 1980s and generated the discussion leading to the establishment of the neighborhood planning program and the neighborhood conservation overlay district. These development patterns, small lot and large lot neighborhoods, are illustrated here with the use of two mythical neighborhoods.
Evaluating Alternative Rural Land Use Policies
Creators: name: Danielson, Leon E.

Year: 1982

description: Land-use planning and policy is highly controversial in rural areas of North Carolina and the South. A major reason for this controversy is the large number of issues identified and perspectives held regarding how land in rural areas should be used. For example, four issues related to farmland retention are: (1) the adequacy of the supply of food and forest products, (2) the maintenance of rural character, open space and life style in rural areas, (3) economic viability of the farm and agribusiness sector in local areas, and (4) whether or not compensation is given when policy implementation results in lost landowner property rights. If some persons desire open space while others are concerned for food supply, it is logical that policies preferred will also be different. The ability of individuals to evaluate rural land use issues and problems, and to decide whether to support or reject policy proposals on issues such as farmland retention, requires an awareness of the full range of alternative policies available and what the consequences of their implementation might be. It is not enough to merely identify whether or not there is a problem; only by evaluating the pros and cons of alternatives can we make an informed decision on whether or not to support any specific proposed solution to problems that might have been identified. The purpose of this paper is to identify alternative rural land use policies being used around the United States and to evaluate their acceptability and effectiveness in dealing with issues and problems identified by urban and rural dwellers.

description: Asheville’s ability to rebuild itself and to foster a vibrant downtown in the second half of the 20th century owes much to its early history. Asheville was a booming town in 1900, an urban center for the mountain area with numerous trading-related businesses. The completion of the railway line to Asheville in 1880 had ushered in a period of increased tourism and development. By the turn of the century, the area hosted a number of health sanitariums that attracted people from far and wide. It was marketed as a beautiful place where people could rest, renew, relax, and recover from illnesses. Ever since this time, tourism has played an important and growing role in Asheville’s economy.

description: We examined the potential of antibody-functionalized single-walled carbon nanotube (SWNT) field-effect transistors (FETs) for use as a fast and accurate sensor for a Lyme disease antigen. Biosensors were fabricated on oxidized silicon wafers using chemical vapor deposition grown carbon nanotubes that were functionalized using diazonium salts. Attachment of Borrelia burgdorferi (Lyme) flagellar antibodies to the nanotubes was verified by Atomic Force Microscopy and electronic measurements. A reproducible shift in the turn-off voltage of the semiconducting SWNT FETs was seen upon incubation with Borrelia burgdorferi flagellar antigen, indicative of the nanotube FET being locally gated by the residues of flagellar protein bound to the antibody. This sensor effectively detected antigen in buffer at concentrations as low as 1 ng/ml, and the response varied strongly over a concentration range coinciding with levels of clinical interest. Generalizable binding chemistry gives this biosensing platform the potential to be expanded to monitor other relevant antigens, enabling a multiple vector sensor for Lyme disease. The speed and sensitivity of this biosensor make it an ideal candidate for development as a medical diagnostic test.

Planning at the Grass Roots Level: The Guilford County Citizen Participation Program

Year: 1976

description: Historically, local governments in this country have focused their programs and priorities almost exclusively on urban areas, where population, resources, and problems are most concentrated. Rural dwellers, by contrast, have been avoided by planners and other officials, their needs being left to such rural-oriented agencies as the Agricultural Extension Service. In the late summer of 1973, Guilford County Government and its citizens broke that tradition. Stimulated primarily by the need to dampen citizen dissatisfaction with land use regulations, the County Government set out to organize the citizens of its rural and suburban areas around community defined issues and problems. What has resulted is a community organization directly involving the citizens of Guilford County. Among their accomplishments to date have been the formation of a summer recreation program, a rural garbage collection study, a rural-suburban land use committee, and a citizen's budget committee. Prior to this effort, "citizen input" into the planning process of Guilford County came only through such conventional arrangements as public hearings on specific proposals, routine board or commission meetings, political representation, or the electoral process. As it was implemented in 1973, the "Community Councils Program" was a significant departure from this norm, because, one, it was non-urban in focus; two, its base was grass-roots community organization rather than individually oriented; and three, it attempted to involve organized county residents early in the planning stages of both short and long-range governmental decisions. Moreover, as a form of decentralization of political power toward the "county-wide" community and toward the local communities, its conceptualization and practice were a far cry from the rubber-stamp public hearing, the hand-picked board or commission, or the infrequent ritual of selecting remote decision-makers through the electoral process.

description: Luminous high-redshift QSOs are thought to exist within the most massive dark matter haloes in the young Universe. As a consequence they are likely to be markers for biased, over-dense regions where early galaxies cluster, regions that eventually grow into the groups and clusters seen in the lower redshift universe. In this paper we explore the clustering of galaxies around z ~ 5 QSOs as traced by Lyman Break Galaxies (LBGs). We target the fields of three QSOs using the same optical imaging and spectroscopy techniques used in the ESO Remote Galaxy Survey (ERGS, Douglas et al. 2009, 2010), which was successful in identifying individual clustered structures of LBGs. We use the statistics of the redshift clustering in ERGS to show that two of the three fields show significant clustering of LBGs at the QSO redshifts. Neither of these fields is obviously over-dense in LBGs from the imaging alone; a possible reason why previous imaging-only studies of high-redshift QSO environments have given ambiguous results. This result shows that luminous QSOs at z ~ 5 are typically found in over-dense regions. The richest QSO field contains at least nine spectroscopically confirmed objects at the same redshift including the QSO itself, seven LBGs and a second fainter QSO. While this is a very strong observational signal of clustering at z ~ 5, it is of similar strength to that seen in two structures identified in the 'blank sky' ERGS fields. This indicates that, while over-dense, the QSO environments are not more extreme than other structures that can be identified at these redshifts. The three richest structures discovered in this work and in ERGS have properties consistent with that expected for proto-clusters and likely represent the early stages in the build-up of massive current-day groups and clusters.
