description: Changes in the size and socioeconomic composition of the population in rural communities have confronted local units of government with the need to make decisions pertaining to investments in public services. This report analyzes public capital expenditures in three rural towns that gained or lost population or maintained a stable population between 1930 and 1965. Results show that towns that are gaining or losing population use different options for funding capital expenditures. The growing town extensively used special property assessments and bonded indebtedness to secure investment capital. The town that lost population during 1930-65 relied primarily on transfers of funds from State and Federal Governments for investment capital. The stable town also used transfers extensively, but its largest source of investment capital came from current revenue, accruals, investment earnings, short-term indebtedness, and other miscellaneous sources. Although expenditure levels varied, the distribution of investment by type of function was similar in each community. Per capita expenditures for water, streets, and sewers were closely associated with population growth rates in the growing town.

Subjects: Corporate Foreign Direct Investment (FDI), Investment Location, Nigeria, Exchange Rate

description: The study examined the factors influencing corporate Foreign Direct Investment (FDI) decisions and investment location and activity in Nigeria. The research was conducted using an OLS regression analysis approach, incorporating quantitative research methods. The study found that FDI has a significant relationship with market size (GDP), and insignificant relationship with exchange rate, inflation rate and degree of trade openness. The findings of the study revealed that several factors influence corporate FDI decisions and investment location and activity in Nigeria. These factors include market size and growth, political stability, infrastructure development, availability of skilled labour, legal and regulatory environment, economic policies, exchange rate, inflation rate and degree of trade openness. Furthermore, the study also highlighted the significant role of corruption in the country, which could deter foreign investors from investing in Nigeria. The research showed that the Nigerian government must address the issue of corruption to create an enabling environment for foreign investors. In addition, the study identified the importance of promoting sustainable investment practices and corporate social responsibility initiatives to enhance FDI inflows and promote economic development in Nigeria. The study recommended that addressing corruption and promoting sustainable investment practices and corporate social responsibility initiatives can enhance FDI inflows and promote economic development in Nigeria. This research provides a foundation for policymakers and investors to make informed decisions regarding FDI in Nigeria

description: We report results from a programme aimed at investigating the temperature of neutral gas in high-redshift damped Lyman-$α$ absorbers (DLAs). This involved (1) HI 21cm absorption studies of a large DLA sample, (2) VLBI studies to measure the low-frequency quasar core fractions, and (3) optical/ultraviolet spectroscopy to determine DLA metallicities and velocity widths. Including literature data, our sample consists of 37 DLAs with estimates of the spin temperature $T_s$ and the covering factor. We find a strong $4σ$) difference between the $T_s$ distributions in high-z (z>2.4) and low-z (z<2.4) DLA samples. The high-z sample contains more systems with high $T_s$ values, $\gtrsim 1000$ K. The $T_s$ distributions in DLAs and the Galaxy are also clearly (~$6σ$) different, with more high-$T_s$ sightlines in DLAs than in the Milky Way. The high $T_s$ values in the high-z DLAs of our sample arise due to low fractions of the cold neutral medium. For 29 DLAs with metallicity [Z/H] estimates, we confirm the presence of an anti-correlation between $T_s$ and [Z/H], at $3.5σ$ significance via a non-parametric Kendall-tau test. This result was obtained with the assumption that the DLA covering factor is equal to the core fraction. Monte Carlo simulations show that the significance of the result is only marginally decreased if the covering factor and the core fraction are uncorrelated, or if there is a random error in the inferred covering factor. We also find evidence for redshift evolution in DLA $T_s$ values even for the z>1 sub-sample. Since z>1 DLAs have angular diameter distances comparable to or larger than those of the background quasars, they have similar efficiency in covering the quasars. Low covering factors in high-z DLAs thus cannot account for the observed redshift evolution in spin temperatures. (Abstract abridged.)

description: In underdeveloped countries in Asia and Africa, non-effective post-harvest technologies and sometimes ideal environmental conditions for development of pests like insects, fungi, rodents and birds, can lead to damage of both raw or processed foods. Losses can achieve considerable proportions in dried vegetables used as food products, particularly in underdeveloped countries where food security problems are a daily basis routine. The major goal of the present study was the identification of insects and fungi associated with maize under local storage conditions in the Angola provinces of de Benguela, Bié, Cuando Cubango, Cuanza sul, Huambo, Huíla, Luanda, Malange and Namibe. A wide range of storage methods for cereals were sampled, from small containers of peasants and small farmers up to the large metal containers used by large agricultural companies and Estates. The achieved results will contribute for food security improvement in Angola and for the maintenance and preservation of good and healthy seeds at the traditional farmers’ community level. The insect pests registered from the studied samples were Cryptolestes ferrugineus, Gnatocerus maxillosus, Liposcelis bostrychophila, Oryzaephilus surinamensis, Rhyzopertha dominica, Sitophilus zeamais, Sitotroga cerealella and Tribolium castaneum. The species Prostephanus truncatus was not found in the studied samples. Fungi in the genus Aspergillus, Fusarium and Penicillium were presented at a high incidence in all samples studied, although the relative abundance of different fungi species varied with the sample location.

description: We demonstrate that collective turbulent-like motion in a bacterial bath can power and steer directed transport of mesoscopic carriers through the suspension. In our experiments and simulations, a microwedge-like "bulldozer" draws energy from a bacterial bath of varied density. We obtain that a maximal transport speed is achieved in the turbulent state of the bacterial suspension. This apparent rectification of random motion of bacteria is caused by polar ordered bacteria inside the cusp region of the carrier, which is shielded from the outside turbulent fluctuations.

description: Mermin's "shut up and calculate!" somehow summarizes the most widely accepted view on quantum mechanics. This conception has led to a rather constraining way to think and understand the quantum world. Nonetheless, a closer look at the principles and formal body of this theory shows that, beyond longstanding prejudices, there is still room enough for alternative tools. This is the case, for example, of Bohmian mechanics. As it is discussed here, there is nothing contradictory or wrong with this hydrodynamical representation, which enhances the dynamical role of the quantum phase to the detriment (to some extent) of the probability density. The possibility to describe the evolution of quantum systems in terms of trajectories or streamlines is just a direct consequence of the fact that Bohmian mechanics (quantum hydrodynamics) is just a way to recast quantum mechanics in the more general language of the theory of characteristics. Misconceptions concerning Bohmian mechanics typically come from the fact that many times it is taken out of context and considered as an alternative theory to quantum mechanics, which is not the case. On the contrary, an appropriate contextualization shows that Bohmian mechanics constitutes a serious and useful representation of quantum mechanics, at the same level as any other quantum picture, such as Schrödinger's, Heisenberg's, Dirac's, or Feynman's, for instance. To illustrate its versatility, two phenomena will be briefly considered, namely dissipation and light interference.

description: The rising prominence of sunflower oil in world edible oil markets has stimulated increased interest in expanded U.S. production. U.S. acreage devoted to oilseed sunflowers has expanded rapidly, with over 600,000 acres grown in 1972. Production has been concentrated in the southern Cotton Belt States and in the Red River Valley area of Minnesota and North Dakota. This report examines recent trends in domestic fats and oils markets and the possible place of sunflower oil in these markets. Estimates are developed of the yield per acre and price required of sunflowerseed to make it competitive with established crops in the two areas. Also, estimates are made of the costs and profitability of processing sunflowerseed in southern screw-press mills.

description: The inspiral and merger of two orbiting black holes is among the most promising sources for the first (hopefully imminent) direct detection of gravitational waves (GWs), and measurements of these signals could provide a wealth of information about astrophysics, fundamental physics and cosmology. Detection and measurement require a theoretical description of the GW signals from all possible black-hole-binary configurations, which can include complicated precession effects due to the black-hole spins. Modelling the GW signal from generic precessing binaries is therefore one of the most urgent theoretical challenges facing GW astronomy. This article briefly reviews the phenomenology of generic-binary dynamics and waveforms, and recent advances in modelling them.

description: We present observations of the dark Gamma-Ray Burst GRB 051008 provided by Swift/BAT, Swift/XRT, Konus-WIND, INTEGRAL/SPI-ACS in the high-energy domain and the Shajn, Swift/UVOT, Tautenburg, NOT, Gemini and Keck I telescopes in the optical and near-infrared bands. The burst was detected only in gamma- and X-rays and neither a prompt optical nor a radio afterglow were detected down to deep limits. We identified the host galaxy of the burst, which is a typical Lyman-break Galaxy (LBG) with R-magnitude of 24.06 +/- 0.10. A redshift of the galaxy of z = 2.77 (-0.20,+0.15) is measured photometrically due to the presence of a clear, strong Lyman-break feature. The host galaxy is a small starburst galaxy with moderate intrinsic extinction (A_V = 0.3 mag) and has a SFR of ~ 60 M_Sun / yr typical for LBGs. It is one of the few cases where a GRB host has been found to be a classical Lyman-break galaxy. Using the redshift we estimate the isotropic-equivalent radiated energy of the burst to be E_iso = (1.15 +/- 0.20) x 10^54 erg. We also provide evidence in favour of the hypothesis that the darkness of GRB 051008 is due to local absorption resulting from a dense circumburst medium.

description: A smart, electronic, modified pitfall trap, for automatic detection of adult beetle pests inside the grain mass is presented. The whole system is equipped with optoelectronic sensors to guard the entrance of the trap in order to detect, time-stamp, and GPS tag the incoming insect. Insect counts as well as environmental parameters that correlate with insect’s population development are wirelessly transmitted to a central monitoring agency in real time, are visualized and streamed to statistical methods to assist effective control of grain pests. The prototype trap was put in a large plastic barrel (120lt) with 80kg maize. Adult beetles of various species were collected from laboratory rearings and transferred to the experimental barrel. Caught beetle adults were checked and counted after 24h and were compared with the counts from the electronic system. Results from the evaluation procedure showed that our system is very accurate, reaching 98-99% accuracy on automatic counts compared with real detected numbers of adult beetles inside the trap. In this work we emphasize on how the traps can be selforganized in networks that collectively report data at local, regional, country, continental, and global scales using the emerging technology of the Internet of Things (IoT). We argue that smart traps communicating through IoT to report in real-time the level of the pest population from the grain mass straight to a human controlled agency can, in the very near future, have a profound impact on the decision making process in stored grain protection.

description: Recent experiments with self-phoretic particles at low concentrations show a pronounced dynamic clustering [I. Theurkauff \emph{et al.}, Phys.\ Rev.\ Lett.\ \textbf{108}, 268303 (2012)]. We model this situation by taking into account the translational and rotational diffusiophoretic motion, which the active particles perform in their self-generated chemical field. Our Brownian dynamics simulations show pronounced dynamic clustering only when these two phoretic contributions give rise to competing attractive and repulsive interactions, respectively. We identify two dynamic clustering states and characterize them by power-law-exponential distributions. In case of mere attraction a chemotactic collaps occurs directly from the gas-like into the collapsed state, which we also predict by mapping our Langevin dynamics on the Keller-Segel model for bacterial chemotaxis.

Exemplars are IUCr’s Checkcif and PDB’s Validation Report. The question arises once editor (and their referees) and database validator are content with an article and underpinning data what are the standard uncertainties on atomic coordinates and atomic displacement parameters? Expansion of digital data archiving allows raw data preservation reaching close to objectivity in science.

•      Puzzlingly Trust is not emphasised. Peer review of articles with underpinning data is a tradition of crystallography including community agreed validation checks as standard to try and ensure Trust. Exemplars are IUCr’s Checkcif and PDB’s Validation Report

•      The question arises, once editor (and their referees) and database validator are content with an article and underpinning data, what are the standard uncertainties on atomic coordinates and atomic displacement parameters? These are needed because a measurement or a parameter of a model without a standard uncertainty estimate is basically rather meaningless.

•      Expansion of digital data archiving allows raw data preservation reaching close to objectivity in science

•      In law the truth, the whole truth and nothing but the truth is sought, so why not in science as well?! The whole truth then being the raw ie primary experimental data for any published study made possible by the new digital data archives with their huge capacities these days compared with the past.

Six palm positions are used to evoke combined somatosensory brain responses, in order to define a novel contact-less tactile BCI. A comparison is made with classical attached vibrotactile transducers. Experiment results of subjects performing online experiments validate the novel BCI paradigm.

Creators: name: Eliopoulos, Panagiotis A.

description: Stored product insects, produce acoustic emissions by moving, feeding or ovipositing inside the grain mass. These sounds can be used not only for detection purposes, but also for population density estimation. Acoustic emissions of adults of Acanthoscelides obtectus (Coleoptera: Bruchidae) and Callosobruchus maculatus (Coleoptera: Chrysomelidae) were recorded infesting various pulses in varying population densities from 1 to 500 adults/kg product. The acoustic analysis system is being described. Population density, type of grain and pest species had significant influence on the number of sounds. The system was 100% precise in negative predictions and considerably successful in positive predictions. The system was very accurate (80-100%) in detecting insect presence even in the “critical” density of 1 adult/kg product, the most common threshold for classifying a stored mass as “infested” or “not infested”. Our study suggests that automatic monitoring of the infestation state in bulk grain is feasible in small containers. This kind of service can assist reliable decision making if it can be transferred to larger storage establishments (eg. silos). Our results are discussed on the basis of enhancing the use of acoustic sensors as a decision support system in stored product IPM.

With the abundance of data provided by Kepler and TESS, it is now possible to study the characteristics of stellar flares in greater detail, beyond the simple parameterization by amplitude and duration. Here we use the FLATW’RM2 deep learning based tool to identify flares on all available Kepler and TESS short cadence light curves, then use principal component analysis to explore the temporal morphology of flares, looking for systematic differences in their shapes after scaling, and also trying to link these differences to the basic astrophysical properties of the stars.

description: The potential for shifting risk through hedging in commodity futures is analyzed for selected grain storage and livestock feeding situations. Results applying to various locations, grades, and/or classes are reported for wheat, corn, oats, cattle, and hogs. Hedging potential is measured in terms of risk-shifting effectiveness--the proportional reduction in the variance of profits that can be obtained through routine hedging. The study indicates that hedging provides an effective means of shifting risk in livestock feeding as well as in grain storage. For most of the situations studied, the level of hedging that minimizes overall profit risk ranges between 0.6 and 1.0 unit of futures per unit of cash commodity. About one-third to two-thirds of the price risk can be shifted through hedging at this level. Hedging effectiveness declines as the distance from the delivery point for the futures contract increases. Hedging effectiveness differs between classes of wheat and among the three wheat futures markets. Grade has little impact on hedging effectiveness in cattle feeding, however. Optimal hedging levels for individual firms are shown to be very sensitive to the firms’ price expectations.

description: Recent examples for the introduction of wood-breeding beetles in Europe include the asian longhorn beetles Anoplophora spp. and Aromia bungii (red-necked longhorn beetle). These and other woodboring beetle species pose a high risk of economic damage to trees and wood products. Smaller beetles like the powderpost beetles from the families Bostrichidae and Lyctidae also have the potential for causing considerable damage. These are often not identified adequately during inspections of wood packaging materials, making it impossible to assess their risk for becoming invasive. This project will aim at closing that gap. Our project PHID-Coleo (= Plant Health Identification of Coleoptera) has the objective to develop new diagnostic tools for the identification of potentially invasive and economically important beetles that can be found in wood packaging materials. The identification methods include classical identification keys based on morphological characters as well as molecular methods based on DNA analysis by PCR (barcoding). The methods for species identification will be supplemented by molecular analyses of introduced populations to clarify within species variations. Such methods will make it possible to determine the taxonomic relationship of samples from different areas and to draw conclusions about the introduction pathways, resulting in more efficient monitoring of the invasive species and preventing their spread. PHID-Coleo will build a freely accessible database of relevant species which are potentially invasive.

Cardozo School of Law in the 1980s. Price describes his experience serving with the President’s Task Force on Communications Policy in Washington in the late 1970s. He also recounts the establishment of the UCLA Communications Law Program, under the leadership of Geoffrey Cowan, around the same time. The session includes Price’s account of his deputy directorship of the Sloan Commission on Cable Communications in the early 1970s, as well as his work on a citizen’s guide to cable television in this period. A sabbatical year in Paris in the early 1970s is touched upon, in terms of its de-centering for Price of the U.S. First Amendment. Price describes his decision to run for a newly established community college board, and his appointment as Referee in the mid-1970s in the aftermath of a major school desegregation case, Crawford v. Board of Education of the City of Los Angeles. Price briefly describes his role in establishing and helping to run an L.A.-based Jewish Television Network. The session touches on Price’s legal scholarship from the period, much of it focused on communication topics. Price provides an account of his deanship at Cardozo, and describes the background and reception of his 1991 book on AIDS, Shattered Mirrors.
Pervasive coexpression of spatially proximal genes is buffered at the protein level

description: Genes are not randomly distributed in the genome. In humans, 10% of protein‐coding genes are transcribed from bidirectional promoters and many more are organised in larger clusters. Intriguingly, neighbouring genes are frequently coexpressed but rarely functionally related. Here we show that coexpression of bidirectional gene pairs, and closeby genes in general, is buffered at the protein level. Taking into account the 3D architecture of the genome, we find that co‐regulation of spatially close, functionally unrelated genes is pervasive at the transcriptome level, but does not extend to the proteome. We present evidence that non‐functional mRNA coexpression in human cells arises from stochastic chromatin fluctuations and direct regulatory interference between spatially close genes. Protein‐level buffering likely reflects a lack of coordination of post‐transcriptional regulation of functionally unrelated genes. Grouping human genes together along the genome sequence, or through long‐range chromosome folding, is associated with reduced expression noise. Our results support the hypothesis that the selection for noise reduction is a major driver of the evolution of genome organisation.

description: Effective descriptions accounting for the evolution of quantum systems that are acted on by a bath are desirable. As the number of bath degrees of freedom increases and full quantum simulations turn out computationally prohibitive, simpler models become essential to understand and gain an insight into the main physical mechanisms involved in the system dynamics. In this regard, vibrational decoherence of an I$_2$ diatomics is tackled here within the framework of Markovian quantum state diffusion. The I$_2$ dynamics are analyzed in terms of an effective decoherence rate, $Λ$, and the specific choice of the initial state, in particular, Gaussian wave packets and two-state superpositions. It is found that, for Markovian baths, the relevant quantity regarding decoherence is the product of friction ($η$) and temperature ($T$); there is no distinction between varying one or the other. It is also observed that decoherence becomes faster as the energy levels involved in the system state correspond to higher eigenvalues. This effect is due to a population redistribution during the dynamical process and an eventual irreversible loss of the initial coherence. These results have been compared with those available in the literature from more detailed semiclassical IVR simulations, finding a good agreement.

description: Stellar flares and coronal mass ejections (CMEs) can have serious effects on their surroundings: they can erode or completely destroy atmospheres of orbiting planets over time and also have high importance in stellar evolution. Most of the stellar CME detections in the literature are single events found serendipitously sparse for statistical investigation. We present a search in archive spectra of dwarf stars from solar-like objects to M-dwarfs aimed to find a large number of stellar CMEs suitable for statistical analysis. For M-dwarfs, we found event rates that are lower than we could expect from the solar paradigm, and no convincing events for solar-like stars. What can be behind this low number of events? Can high-resolution solar spectra help us to learn more on stellar CMEs?

description: High-throughput technologies are now widely used in the life sciences field and are producing ever-increasing amounts and diversity of data. While many laboratories and even undergraduate students generate high-throughput data, analyzing these results requires a skill set that is traditionally reserved for bioinformaticians. Learning to program using languages such as R and Python and making sense of the vast amounts of available omics data have become easier, thanks to the multitude of available resources. This can empower bench-side researchers to perform more complex computational analyses. Tools such as KNIME or Galaxy (together with a growing number of tutorials and courses) have been crucial in providing simple user interfaces to conduct complex analyses under the hood, making the ‘big data’ revolution accessible to biologists. High-throughput methodologies and machine learning have been central in developing systems-level perspectives in molecular biology. Unfortunately, performing such integrative analyses has traditionally been reserved for bioinformaticians. This is now changing with the appearance of resources to help bench-side biologists become skilled at computational data analysis and handling large omics data sets. Here, we show an entry route into the field of omics data analytics. We provide information about easily accessible data sources and suggest some first steps for aspiring computational data analysts. Moreover, we highlight how machine learning is transforming the field and how it can help make sense of biological data. Finally, we suggest good starting points for self-learning and hope to convince readers that computational data analysis and programming are not intimidating.

description: Functional Electrical Stimulation via electrode arrays enables the user to form virtual electrodes (VEs) of dynamic shape, size, and position. We developed a feedback-control-assisted manual search strategy which allows the therapist to conveniently and continuously modify VEs to find a good stimulation area. This works for applications in which the desired movement consists of at least two degrees of freedom. The virtual electrode can be moved to arbitrary locations within the array, and each involved element is stimulated with an individual intensity. Meanwhile, the applied global stimulation intensity is controlled automatically to meet a predefined angle for one degree of freedom. This enables the therapist to concentrate on the remaining degree(s) of freedom while changing the VE position. This feedback-control-assisted approach aims to integrate the user's opinion and the patient's sensation. Therefore, our method bridges the gap between manual search and fully automatic identification procedures for array electrodes. Measurements in four healthy volunteers were performed to demonstrate the usefulness of our concept, using a 24-element array to generate wrist and hand extension.

description: Functional Electrical Stimulation (FES) facilitates the motor recovery of the hand function after stroke. The integration of biofeedback and other strategies to actively involve a patient in the therapy is important for the rehabilitation progress. We introduce a combined control approach for a FES-driven neuroprosthesis using volitional electromyo-graphy (vEMG) and motion capturing via a novel inertial sensor network for patients that still possess a residual activity in the paralyzed muscles. A real-time vEMG measurement and signal processing in between stimulation pulses has been realized during active FES. Experiments showed that our system allows for quick adaption to individual users.

description: The dimensions that influence the establishment of business process management (BPM) practices and the progression to higher levels of process maturity derive from exploring the dimensions of process orientation of organizations. Small and medium-sized clothing enterprises (SME’s) are characterized by various specifics that can affect the degree of process orientation adoption and the pace of transition from lower to higher levels of process maturity. According to these specifics, the acceptance of the process approach may be differently affected. For the purpose of adequate evaluation and prioritization of the most influential dimensions, a new integrated multicriteria decision-making (MCDM) model that combines classical and fuzzy theory was developed. First, the full consistency method (FUCOM) method was applied, followed by the fuzzy pivot pairwise relative criteria importance assessment (fuzzy PIPRECIA) method to obtain more accurate criteria values. Prioritization of the most influential BPM dimension contributes to highlighting the area of business that needs to be primarily strengthened by appropriate actions for successful establishment of BPM in apparel industry SMEs. Within this research, the prioritized dimension refers to human resource management in accordance with the specific aspects of business within the apparel industry.

description: Governments around the world are introducing single-use plastics bans to alleviate plastic marine pollution. This paper investigates whether banning single-use plastic items is an appropriate strategy to protect the environment. Product life cycle assessment was conducted for single-use plastic and single-use non-plastic alternatives. The life cycle impacts of the two product categories were compared and scaled according to EU consumption of 2016. The results show that a single-use plastics ban would decrease plastic marine pollution in the EU by 5.5% which equates to a 0.06% decrease globally. However, such a ban would increase emissions contributing to marine aquatic toxicity in the EU by 1.4%. This paper concludes that single-use items are harmful to the environment regardless of their material. Therefore, banning or imposing a premium price on single-use items in general and not only single-use plastic items is a more effective method of reducing consumption and thereby pollution. The plastics ban only leads to a small reduction of global plastic marine pollution and thus provides only a partial solution to the problem it intends to solve.

The inelastic vs. total nucleon-nucleon cross section at large $N_c$

description: In this paper, the implication of the extreme large $N_c$ limit for nucleon-nucleon cross section is examined. Starting from the $N_c$ scaling of the S-matrix elements, a relation between the total inelastic and total cross sections is derived for the regime in which the momenta are much larger than the QCD scale. A conceptual complication arise from the fact that there is a tower of baryons, such as the $Δ$, with mass splittings from the nucleon which go to zero at large $N_c$. Since these baryons are stable at large $N_c$, the meaning of elasticity must be modified. Processes which only transform nucleons to these baryons are considered elastic; processes in which at least one additional meson is produced are considered inelastic. It is shown that in the extreme large $N_c$ limit, the total inelastic cross section is exactly one eighth of the total cross section. In contrast, in the physical world of $N_c=3$ the total cross section for high-energy nucleon-nucleon scattering is dominated by inelastic processes.

description: Diamond has recently attracted considerable attention as a promising platform for quantum technologies, photonics and high resolution sensing applications. Here we demonstrate a chemical approach that enables the fabrication of functional diamond structures using gas-mediated electron induced etching. The method achieves chemical etching at room temperature through the dissociation of surface-adsorbed H2O molecules by electron irradiation in a water vapor environment. High throughput, parallel processing is possible by electron flood exposure and the use of an etch mask, while single step, mask-free three dimensional fabrication and iterative editing are achieved using a variable pressure scanning electron microscope. The electron induced chemical etching paves the way to a transformative technology for nanofabrication of diamond and other wide band-gap semiconductors.

description: Spoof surface modes on nanostructured metallic surfaces are known to have tailorable dispersion dependent on the geometric characteristics of the periodic pattern. Here we examine the spoof plasmon dispersion on an isolated grating and a grating-planar mirror cavity configuration. The spoof polariton dispersion in the cavity is obtained using the scattering matrix approach, and the related differential modal density of states is introduced to obtain the mode dispersion and classify the cavity polariton modes. The grating-mirror cavity geometry is an example of periodically nanostructured metals above a planar ground plane. The properties discussed here are relevant for applications ranging from thin electromagnetic perfect absorbers to near-field radiative heat transfer.
