description: In this paper we present a detailed spectroscopic analysis of the suspected marginal Am star HD\,71297. Our goal is to test the accuracy of two different approaches to determine the atmospheric parameters effective temperature, gravity, projected rotational velocity, and chemical abundances. The methods used in this paper are: classical spectral synthesis and the {\it Versatile Wavelength Analysis} ({\sl VWA}) software. Since our star is bright and very close to the Sun, we were able to determine its effective temperature and gravity directly through photometric, interferometric, and parallax measurements. The values found were taken as reference to which we compare the values derived by spectroscopic methods. Our analysis leads us to conclude that the spectroscopic methods considered in this study to derive fundamental parameters give consistent results, if we consider all the sources of experimental errors, that have been discussed in the text. In addition, our study shows that the spectroscopic results are quite as accurate as those derived from direct measurements. As for the specific object analyzed here, according to our analysis, HD\,71297 has chemical abundances not compatible with the previous spectral classification. We found moderate underabundances of carbon, sodium, magnesium, and iron-peak elements, while oxygen, aluminum, silicon, sulfur, and heavy elements (Z $\geq$ 39) are solar in content. This chemical pattern has been confirmed by the calculations performed with both methods.

description: The structures, cohesive energies and HOMO-LUMO gaps of graphene nanoflakes and corresponding polycyclic aromatic hydrocarbons for a large variety of size and topology are investigated at the density functional based tight-binding level. Polyacene-like and honeycomb-like graphene nanoflakes were chosen as the topological limit structures. The influence of unsaturated edge atoms and dangling bonds on the stability is discussed. Our survey shows a linear trend for the cohesive energy as function of Ns/N (N - total number of atoms and Ns is number of edge atoms). For the HOMO-LUMO gap the trends are more complex and include also the topology of the edges.

Crime prevention through environmental design: A comparative analysis of two Las Vegas apartment complexes
Creators: name: Hardy, Kim Michelle
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: Many case studies have been published that report a reduction in crime as a result of crime prevention through environmental design (CPTED). Although methodologies and results of some studies have been questioned, there is agreement that the designed environment can influence human behavior; Findings in this study were generated by the analysis of two Las Vegas apartment complexes. Managers at one complex reported eliminating burglaries after providing individual gardens for their residents. My hypothesis was that the addition of gardens to existing characteristics at the study complex provided a high number of CPTED features which would result in a low number of police calls for service. Police calls for service from 1989 through 1994 and CPTED elements were analyzed. Results indicated a higher number of police calls for service were initiated from the study complex. The conclusion was that residents of the study complex were more sensitized to potential troublesome activities and therefore reported suspicious activities to the police more frequently.
Psychosocial support needs of people with diabetes during the COVID-19 pandemic: Informing a rapid transition to community-led, videoconference-based peer support for diabetes self-management

description: Background: Community-led peer support groups provide a highly valuable support network for people living with diabetes. The coronavirus COVID-19 pandemic generated multiple self-management challenges for these individuals, and it widely disrupted health and social care access. In response, a leading diabetes charitable organisation partnered with researchers to rapidly investigate the opinions of people living with diabetes regarding the use of videoconferencing to re-start peer support group meetings. Methods: Three focus groups were conducted in May 2020 using a videoconferencing platform. Convenience sampling was used to recruit 19 people living with type 1 (n=12) or type 2 (n=7) diabetes. The focus groups were audio-recorded. An inductive thematic analysis was conducted after familiarisation with the transcripts. Four inter-related themes emerged. Results: Participants believed peer support would be a valuable source of emotional support and reliable information, given the disrupted access to healthcare teams. Videoconferencing platforms were deemed to be able to offer more opportunities for health professional involvement and expand the types of peer support people can access. Challenges were identified, including greater demands on group facilitators, risk of exclusion and connecting people to these groups. In conclusion, this study showed that people with diabetes welcome a transition to videoconference-based peer support group meetings during the pandemic, contingent on efforts being made to ensure equitable benefit. Conclusions: Peer support providers should consider videoconferencing as an alternative way to provide ongoing support. Organisations should work closely with diabetes care specialists and social prescribers to help set up the groups and increase accessibility.
A series test of the scaling limit of self-avoiding walks

description: It is widely believed that the scaling limit of self-avoiding walks (SAWs) at the critical temperature is (i) conformally invariant, and (ii) describable by Schramm-Loewner Evolution (SLE) with parameter $κ= 8/3.$ We consider SAWs in a rectangle, which originate at its centre and end when they reach the boundary. We assume that the scaling limit of SAWs is describable by ${\rm SLE}_κ,$ with the value of $κ$ to be determined. It has previously been shown by Guttmann and Kennedy \cite{GK13} that, in the scaling limit, the ratio of the probability that a SAW hits the side of the rectangle to the probability that it hits the end of the rectangle, depends on $κ.$ By considering rectangles of fixed aspect ratio 2, and also rectangles of aspect ratio 10, we calculate the probabilities exactly for larger and larger rectangles. By extrapolating this data to infinite rectangle size, we obtain the estimate $κ= 2.66664 \pm 0.00007$ for rectangles of aspect ratio 2 and $κ= 2.66675 \pm 0.00015$ for rectangles of aspect ratio 10. We also provide numerical evidence supporting the conjectured distribution of SAWs striking the boundary at various points in the case of rectangles with aspect ratio 2.

Channeling of a sub-angstrom electron beam in a crystal mapped to two-dimensional molecular orbitals

description: The propagation of high-energy electrons in crystals is in general a complicated multiple scattering problem. However, along high-symmetry zone axes the problem can be mapped to the time evolution of a two-dimensional (2D) molecular system. Each projected atomic column can be approximated by the potential of a 2D screened hydrogenic atom. When two columns are in close proximity, their bound states overlap and form analogs to molecular orbitals. For sub-angstrom electron beams, excitation of anti-symmetric orbitals can result in the failure of the simple incoherent imaging approximation. As a result, the standard resolution test and the one-to-one correspondence of atomic positions of a crystal imaged along a zone-axis with closely spaced projected columns ("dumbbells") can fail dramatically at finite and realistic sample thicknesses. This is demonstrated experimentally in high angle annular dark field scanning transmission electron microscope (HAADF STEM) images of [211]-oriented Si showing an apparent inter-column spacing of 1.28(+-.09) Angstroms, over 64% larger than the actual 0.78 Angstrom spacing. Furthermore, the apparent spacing can be tuned with sample thickness and probe size to produce a larger, smaller, or even the actual spacing under conditions when the peaks of two adjacent Si columns should not even have been resolved given the electron probe size.

description: In this work we present an active Compton scattering polarimeter as a focal plane instrument able to extend the X-ray polarimetry towards hard X-rays. Other authors have already studied various instrument design by means of Monte Carlo simulations, in this work we will show for the first time the experimental measurements of "tagging efficiency" aimed to evaluate the polarimeter sensitivity as a function of energy. We performed a characterization of different scattering materials by measuring the tagging efficiency that was used as an input to the Monte Carlo simulation. Then we calculated the sensitivity to polarization of a design based on the laboratory set-up. Despite the geometry tested is not optimized for a realistic focal plane instrument, we demonstrated the feasibility of polarimetry with a low energy threshold of 20 keV. Moreover we evaluated a Minimum Detectable Polarization of 10% for a 10 mCrab source in 100 ks between 20 and 80 keV in the focal plane of one multilayer optics module of NuSTAR. The configuration used consisted of a doped p-terphenyl scatterer 3 cm long and 0.7 cm of diameter coupled with a 0.2 cm thick LaBr3 absorber.

description: In this paper, we describe some recent results obtained in the context of vector subdivision schemes which possess the so-called full rank property. Such kind of schemes, in particular those which have an interpolatory nature, are connected to matrix refinable functions generating orthogonal multiresolution analyses for the space of vector-valued signals. Corresponding multichannel (matrix) wavelets can be defined and their construction in terms of a very efficient scheme is given. Some examples illustrate the nature of these matrix scaling functions/wavelets.
Ethics and the moral limits of policy
Creators: name: Khosropur, Marlene Beverly
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: Implementation is often the orphan of the policy creation process, causing problems that raise ethical warning flags. When drafting policy, flexibility is often absent from programs. Discretionary powers are denied to implementors, resulting in a condition of abstracted judgment that can cripple or derail the original intent. For example, government policies toward the aging often create and form perceptions that radiate outwardly, becoming assimilated by corporations and institutions, and hardened into programs that are often implemented unsoundly. The moral composition of a community is affected. Society absorbs fragments of thought generated by these policies and forms biases and prejudices that it, in turn, often uses negatively in assessing the value and rights of older citizens. Mandatory retirement at age 65 and more specifically, the Social Security program, are examples of policies that may have once held merit but have either become obsolete or harmful, or both.

description: Email service providers have employed many email classification and prioritization systems over the last decade to improve their services. In order to assist email services, we propose a personalized email community detection method to discover the groupings of email users based on their structural and semantic intimacy. We extract the personalized social graph from a set of emails by uniquely leveraging each node with communication behavior. Subsequently, collaborative similarity measure (CSM) based intra-graph clustering approach detects personalized communities. The empirical analysis shows effectiveness of the resultant communities in terms of evaluation measures, i.e. density, entropy and f-measure. Moreover, email strainer, dynamic group prediction, and fraudulent account detection are suggested as the potential applications from both the service provider and user's point of view.

A critical evaluation of the Dolby Digital compression algorithm
Creators: name: Ingbretsen, David Andrew
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: Dolby Digital, or AC-3, provides for the compression of high-quality audio signals at a bit rate of 384 kbps. for 5.1 audio channels. The purpose of this thesis is to conduct an analysis and evaluation of the AC-3 compression algorithm. The main conclusion is that AC-3 allocates too few bits to the upper frequency ranges. This conclusion is supported by two lines of argument. First, a comparison of the AC-3 perceptual coding model with known facts concerning the masking properties of sound reveals omissions in the AC-3 perceptual model that lead to loss of high frequency resolution. Second, a test program comparing the bit allocation generated by AC-3 with the bit allocation generated by MPEG corroborates the conclusion. A remedy for the high frequency loss problem is put forward.

description: The process of collecting and organizing sets of observations represents a common theme throughout the history of science. However, despite the ubiquity of scientists measuring, recording, and analyzing the dynamics of different processes, an extensive organization of scientific time-series data and analysis methods has never been performed. Addressing this, annotated collections of over 35 000 real-world and model-generated time series and over 9000 time-series analysis algorithms are analyzed in this work. We introduce reduced representations of both time series, in terms of their properties measured by diverse scientific methods, and of time-series analysis methods, in terms of their behaviour on empirical time series, and use them to organize these interdisciplinary resources. This new approach to comparing across diverse scientific data and methods allows us to organize time-series datasets automatically according to their properties, retrieve alternatives to particular analysis methods developed in other scientific disciplines, and automate the selection of useful methods for time-series classification and regression tasks. The broad scientific utility of these tools is demonstrated on datasets of electroencephalograms, self-affine time series, heart beat intervals, speech signals, and others, in each case contributing novel analysis techniques to the existing literature. Highly comparative techniques that compare across an interdisciplinary literature can thus be used to guide more focused research in time-series analysis for applications across the scientific disciplines.
Message routing between the As/400 token ring network and the Internet

description: A working model of the message exchange system is designed and developed for the AS/400 systems, a type of mid-range computer developed by IBM, thus enabling the Message Routing between the AS/400 Token Ring Network and the Internet. The routing system accommodates the in-built messaging function in the midrange computer, hence providing a common familiar interface to the user. The message system typically includes a router and an intermediate host system connected to a computer which provides the access to the Internet (technically referred as Internet Gateway). The router becomes the bridging unit between the Internet and the midrange host. The router uses two different protocols to communicate with the midrange host and the Internet. However the message exchanges are never affected by these differences in the protocol, since they are accomplished at a higher level of communication.

description: Sign Language Recognition has emerged as one of the important area of research in Computer Vision. The difficulty faced by the researchers is that the instances of signs vary with both motion and appearance. Thus, in this paper a novel approach for recognizing various alphabets of Indian Sign Language is proposed where continuous video sequences of the signs have been considered. The proposed system comprises of three stages: Preprocessing stage, Feature Extraction and Classification. Preprocessing stage includes skin filtering, histogram matching. Eigen values and Eigen Vectors were considered for feature extraction stage and finally Eigen value weighted Euclidean distance is used to recognize the sign. It deals with bare hands, thus allowing the user to interact with the system in natural way. We have considered 24 different alphabets in the video sequences and attained a success rate of 96.25%.

Identifying and illustrating urban traffic congestion, mobility, and accessibility using a Gis
Creators: name: Jensen, Jeffrey James
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: Urban congestion, accessibility, and mobility are important concerns affecting the quality of life in metropolitan areas. It is important that accessibility and mobility should not be compromised while developing strategies to alleviate congestion. The effects of traffic congestion include not only increase travel delays, which result in the increase of travel times, but also impacts energy consumption and air quality. All of these have detrimental effects on the quality of life. In order to develop strategies to alleviate urban congestion, it is necessary to first identify where and when congestion occurs--i.e., the spatial and temporal distribution of congestion. The objective of this research is to demonstrate the application of a geographic information system (GIS) to help identify and illustrate urban congestion, accessibility, and mobility. Definitions of mobility, accessibility, and congestion are presented as well as the advantages of using a GIS. A list of performance measures which are typically used to quantify these transportation functions are discussed. Data required to quantify the performance measures, their sources and integration within a GIS are discussed. Lastly GIS analyses used to quantify the performance measure are discussed. The performance measures used are: (1) non-recurring delay, (2) average vehicle occupancy, (3) business and employee accessibility to transit routes, (4) residential accessibility to transit routes, (5) Transit accessibility to areas of low automobile ownership, and finally (6) travel time. Specific example are presented to illustrate the application of GIS to evaluate the performance measures identified. In turn, these can be used to develop policies and operational strategies to address congestion (and potential congestion), mobility, and accessibility issues in urban areas. Conclusions are the GIS is a viable tool to assist planners and engineers to identify problem areas using already existing data sources.

description: We present continuum observations of the infrared dark cloud (IRDC) G48.66-0.22 (G48) obtained with Herschel, Spitzer, and APEX, in addition to several molecular line observations. The Herschel maps are used to derive temperature and column density maps of G48 using a model based on a modified blackbody. We find that G48 has a relatively simple structure and is relatively isolated; thus this IRDC provides an excellent target to study the collapse and fragmentation of a filamentary structure in the absence of complicating factors such as strong external feedback. The derived temperature structure of G48 is clearly non-isothermal from cloud to core scale. The column density peaks are spatially coincident with the lowest temperatures (~ 17.5 K) in G48. A total cloud mass of ~390Msun is derived from the column density maps. By comparing the luminosity-to-mass ratio of 13 point sources detected in the Herschel/PACS bands to evolutionary models, we find that two cores are likely to evolve into high-mass stars (M>8 Msun). The derived mean projected separation of point sources is smaller than in other IRDCs but in good agreement with theoretical predications for cylindrical collapse. We detect several molecular species such as CO, HCO+, HCN, HNC and N2H+. CO is depleted by a factor of ~3.5 compared to the expected interstellar abundance, from which we conclude that CO freezes out in the central region. Furthermore, the molecular clumps, associated with the sub-millimeter peaks in G48, appear to be gravitationally unbound or just pressure confined. The analysis of critical line masses in G48 show that the entire filament is collapsing, overcoming any internal support.

A case study in political rhetoric: Political and religious cohesion in the South
Creators: name: Harrington-Donnell, Shauna S
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: This study of political and religious rhetoric questions the means by which a staunch religious individual becomes successful in the political arena. The overt religious and political rhetoric of Governor Mike Huckabee (R-AR), who is also an ordained Baptist minister, is analyzed by method of textual analysis. Three speeches from different contexts are examined with the assistance of the Q.S.R. NUD.IST program for qualitative data analysis. The findings indicate that Huckabee's success in both ideological realms has occurred while using primarily three rhetorical tools to build ethos with the secular populace: self-disclosure, logic via example, and secular humor. Although, not apodictic, this investigation will serve in constituting rhetorical frameworks for the religious-based politician.
Nonlinear Correction to the Euler Buckling Formula for Compressed Cylinders with Guided-Guided End Conditions

description: Euler's celebrated buckling formula gives the critical load $N$ for the buckling of a slender cylindrical column with radius $B$ and length $L$ as \[ N / (π^3 B^2) = (E/4)(B/L)^2, \] where $E$ is Young's modulus. Its derivation relies on the assumptions that linear elasticity applies to this problem, and that the slenderness $(B/L)$ is an infinitesimal quantity. Here we ask the following question: What is the first nonlinear correction in the right hand-side of this equation when terms up to $(B/L)^4$ are kept? To answer this question, we specialize the exact solution of incremental non-linear elasticity for the homogeneous compression of a thick compressible cylinder with lubricated ends to the theory of third-order elasticity. In particular, we highlight the way second- and third-order constants ---including Poisson's ratio--- all appear in the coefficient of $(B/L)^4$.

description: Although the leading-order scaling of entanglement entropy is non-universal at a quantum critical point (QCP), sub-leading scaling can contain universal behaviour. Such universal quantities are commonly studied in non-interacting field theories, however it typically requires numerical calculation to access them in interacting theories. In this paper, we use large-scale T=0 quantum Monte Carlo simulations to examine in detail the second Rényi entropy of entangled regions at the QCP in the transverse-field Ising model in 2+1 space-time dimensions -- a fixed point for which there is no exact result for the scaling of entanglement entropy. We calculate a universal coefficient of a vertex-induced logarithmic scaling for a polygonal entangled subregion, and compare the result to interacting and non-interacting theories. We also examine the shape-dependence of the Rényi entropy for finite-size toroidal lattices divided into two entangled cylinders by smooth boundaries. Remarkably, we find that the dependence on cylinder length follows a shape-dependent function calculated previously by Stephan {\it et al.} [New J. Phys., 15, 015004, (2013)] at the QCP corresponding to the 2+1 dimensional quantum Lifshitz free scalar field theory. The quality of the fit of our data to this scaling function, as well as the apparent cutoff-independent coefficient that results, presents tantalizing evidence that this function may reflect universal behaviour across these and other very disparate QCPs in 2+1 dimensional systems.

Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: This study examines two recent gay-themed films (Philadelphia and To Wong Foo, Thanks for Everything Julie Newmar) using Fisher's Narrative Theory. The researcher wants to discover how the films gained success given their controversial themes. The films are analyzed based on the presence of Reich's cultural myths and Reike and Sillars' value systems. The purpose is to show how the presence of elements in the films, that Americans already accept as true, makes the newer, controversial elements more engaging. The study finds an overwhelming presence of cultural myths and value systems that qualifies both films as persuasive devices. Background on popular opinion toward homosexuals as well as homosexual themes in other forms of media is also included.

description: Surveys with the Spitzer and Herschel space observatories are now enabling the discovery and characterization of large samples of protostars in nearby molecular clouds, providing the observational basis for a detailed understanding of star formation in diverse environments. We are pursuing this goal with the Herschel Orion Protostar Survey (HOPS), which targets 328 Spitzer-identified protostars in the Orion molecular clouds, the largest star-forming region in the nearest 500 pc. The sample encompasses all phases of protostellar evolution and a wide range of formation environments, from dense clusters to relative isolation. With a grid of radiative transfer models, we fit the 1-870 micron spectral energy distributions (SEDs) of the protostars to estimate their envelope densities, cavity opening angles, inclinations, and total luminosities. After correcting the bolometric luminosities and temperatures of the sources for foreground extinction and inclination, we find a spread of several orders of magnitude in luminosity at all evolutionary states, a constant median luminosity over the more evolved stages, and a possible deficit of high-inclination, rapidly infalling envelopes among the Spitzer-identified sample. We have detected over 100 new sources in the Herschel images; some of them may fill this deficit. We also report results from modeling the pre- and post-outburst 1-870 micron SEDs of V2775 Ori (HOPS 223), a known FU Orionis outburster in the sample. It is the least luminous FU Ori star with a protostellar envelope.

description: The respiratory rate is an important vital parameter that provides information about persons’physical condition. In clinical practice it is currently only monitored using contact-based techniques, whichcan have negative effects on patients. In this study, a new algorithm for remote respiratory rate recognitionis presented using photoplethysmographic signals derived from facial video images in the visible lightspectrum. The effects of different implementation steps in the presented algorithm are investigated in orderto optimize the approach and gain new findings in this research field. In addition, a detailed examinationof already implemented procedures is performed and the results are compared on two different databases.We show that by fusing the results of seven different respiratory-induced modulations in combination withother processing steps, very good estimates for the respiratory rate on both moving and non-moving dataare achieved. The obtained detection rates of 72.16 % and 87.68 % are significantly higher than those of thebest comparison algorithm with 37.37 % and 59.13 %. The comparison algorithms developed so far are notcompetitive with the newly designed method, especially for video recordings involving persons in motion.This paper provides important new findings in the field of facial video-based respiratory rate recognition forthe research community. A new method has been created that delivers significantly better estimates of therespiratory rate than previously developed techniques.

description: The stability and the predictability of a computer network algorithm's performance are as important as the main functional purpose of networking software. However, asserting or deriving such properties from the finite state machine implementations of protocols is hard and, except for singular cases like TCP, is not done today. In this paper, we propose to design and study run-time environments for networking protocols which inherently enforce desirable, predictable global dynamics. To this end we merge two complementary design approaches: (i) A design-time and bottom up approach that enables us to engineer algorithms based on an analyzable (reaction) flow model. (ii) A run-time and top-down approach based on an autonomous stack composition framework, which switches among implementation alternatives to find optimal operation configurations. We demonstrate the feasibility of our self-optimizing system in both simulations and real-world Internet setups.
Estimating Pareto's constant and Gini coefficient of the Pareto distribution
Creators: name: Hodge, Brian Christopher
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: The Pareto distribution is widely used to describe the distribution of incomes. The distribution can be defined by a location parameter c and a shape parameters a. The maximum likelihood estimators (MLE) and the uniform minimum variance unbiased estimators (UMVUE) for parameters a and c are available in current literature. An improved estimator for parameter a will then be found using a frequentist decision theoretic technique. It is then shown that this improved estimator is the generalized bayes estimator for a certain choice of priors; The Lorenz curve is a tool used to evaluate the share of income of sub-populations or to measure the inequality of individual income distributions. The Lorenz curve for the Pareto distribution will be discussed; The Gini coefficient is a summary measure of the Lorenz curve. The Gini coefficient for the Pareto distribution will be shown to be a function of shape parameter a. The MLE of the Gini coefficient will be discussed. An alternative estimator for the Gini coefficient will then be constructed by using the generalized bayes approach.

description: We present observations of the molecular gas in the nuclear environment of three prototypical low luminosity AGN (LLAGN), based on VLT/SINFONI AO-assisted integral-field spectroscopy of H2 1-0 S(1) emission at angular resolutions of ~0.17". On scales of 50-150 pc the spatial distribution and kinematics of the molecular gas are consistent with a rotating thin disk, where the ratio of rotation (V) to dispersion (sigma) exceeds unity. However, in the central 50 pc, the observations reveal a geometrically and optically thick structure of molecular gas (V/sigma<1 and N_H>10^{23} cm^{-2}) that is likely to be associated with the outer extent of any smaller scale obscuring structure. In contrast to Seyfert galaxies, the molecular gas in LLAGN has a V/sigma<1 over an area that is ~9 times smaller and column densities that are in average ~3 times smaller. We interpret these results as evidence for a gradual disappearance of the nuclear obscuring structure. While a disk wind may not be able to maintain a thick rotating structure at these luminosities, inflow of material into the nuclear region could provide sufficient energy to sustain it. In this context, LLAGN may represent the final phase of accretion in current theories of torus evolution. While the inflow rate is considerable during the Seyfert phase, it is slowly decreasing, and the collisional disk is gradually transitioning to become geometrically thin. Furthermore, the nuclear region of these LLAGN is dominated by intermediate-age/old stellar populations (with little or no on-going star formation), consistent with a late stage of evolution.

description: Parthenium hysterophorus is an invasive weed, produces a lot of non edible biomass that is hazardous to humans. This study provides an insight to its beneficial use by converting the biomass into value-added materials like compost and biochar and subsequent amendment in soil as fertilizer. The biochar was prepared in a locally fabricated charcolator while the compost was prepared in a rolling tumbler. Two-year field experiment was set up using different combinations of biochar (BC), compost (C) and commercial fertilizer (CF) in the rice-wheat cultivation system in Lahore, Pakistan to assess soil health and crops performance after characterizing the products using advanced analyses. GCMS analysis has revealed the presence of stigmasterol and campesterol (plant growth promoters) in prepared compost. Field data showed that the combined application of compost and biochar in rice and wheat fields significantly improved the characteristics of soil like SOM and CEC. Agronomic characteristics such as the number of grains per tiller, grain weight and biological yield were significantly higher in C + CF (half dose of each) and almost equal to CF in the first year. In the second year, both crops agronomic performance was considerably more evident and pronounced following the same pattern. All other agronomic features also followed the same pattern. Thus, mixed application of organic and inorganic fertilizer on recurrent basis is recommended to improve yield of wheat and rice along with soil amelioration in the rice wheat cultivation system.

description: Certified organic farmers who grow mixed vegetables often rely on composted manure as their primary nutrient source to build soil organic matter and long-term fertility, but this can result in excessive phosphorus inputs relative to processed organic fertilizers. We established a two-year experiment to compare two certified organic fertilizers − 13-0-0 (derived from hydrolyzed feather meal, meat meal, and blood meal) and 10-2-8 (same components as 13-0-0 in addition to bone meal and sulfate of potash) – and composted chicken manure added to provide 112 kg plant-available N ha−1 in organic cabbage production of Northern Florida. Crown diameter was highest with processed fertilizers in both years, whereas SPAD readings were highest with 13-0-0 in 2020. In both years, sap nitrate measured during the growing season was generally higher with processed fertilizers relative to the composted manure treatment. Marketable yield was highest with processed fertilizers for both years and nutrient concentrations at harvest were similar among treatments, except for nitrogen concentrations that were highest with 10-2-8 in 2021. Nutrient export generally followed differences in yields and was comparable for processed fertilizers and composted manure. Using composted manure resulted in large nutrient surpluses, as opposed to smaller surpluses for 10-2-8 and deficits of phosphorus and potassium for 13-0-0. Our results confirm that poultry manure composted directly onsite can result in comparable organic cabbage yields relative to processed fertilizers, although this resulted in important phosphorus surpluses when applied to meet crop N demand.

description: Modeling nanoscale devices quantum mechanically is a computationally challenging problem where new methods to solve the underlying equations are in a dire need. In this paper, we present an approach to calculate the charge density in nanoscale devices, within the context of the non equilibrium Greens function approach. Our approach exploits recent advances in using an established graph partitioning approach. The developed method has the capability to handle open boundary conditions that are represented by full self energy matrices required for realistic modeling of nanoscale devices. Our method to calculate the electron density has a reduced complexity compared to the established recursive Greens function approach. As an example, we apply our algorithm to a quantum well superlattice and a carbon nanotube, which are represented by a continuum and tight binding Hamiltonian respectively, and demonstrate significant speed up over the recursive method.
