description: Forest ecosystems in the southern United States are dramatically altered by three major disturbances: timber harvesting, hurricane, and permanent land conversion. Understanding and quantifying effects of disturbance on forest carbon, nitrogen, and water cycles is critical for sustainable forest management in this region. In this study, we introduced a process-based ecosystem model for simulating forest disturbance impacts on ecosystem carbon, nitrogen, and water cycles. Based on forest mortality data classified from Landsat TM/ETM+images, this model was then applied to estimate changes in carbon storage using Mississippi and Alabama as a case study. Mean annual forest mortality rate for these states was 2.37%. Due to frequent disturbance, over 50% of the forest land in the study region was less than 30years old. Forest disturbance events caused a large carbon source (138.92 Tg C, 6.04 Tg C yr(-1); 1 Tg=10(12)g) for both states during 1984-2007, accounting for 2.89% (4.81% if disregard carbon storage changes in wood products) of the total forest carbon storage in this region. Large decreases and slow recovery of forest biomass were the main causes for carbon release. Forest disturbance could result in a carbon sink in few areas if wood product carbon was considered as a local carbon pool, indicating the importance of accounting for wood product carbon when assessing forest disturbance effects. The legacy effects of forest disturbance on ecosystem carbon storage could last over 50years. This study implies that understanding forest disturbance impacts on carbon dynamics is of critical importance for assessing regional carbon budgets.

description: While spatial heterogeneity of riverine nitrogen (N) loading is predominantly driven by the magnitude of basin-wide anthropogenic N input, the temporal dynamics of N loading are closely related to the amount and timing of precipitation. However, existing studies do not disentangle the contributions of heavy precipitation versus non-heavy precipitation predicted by future climate scenarios. Here, we explore the potential responses of N loading from the Mississippi Atchafalaya River Basin to precipitation changes using a well-calibrated hydro-ecological model and Coupled Model Intercomparison Project Phase 5 climate projections under two representative concentration pathway (RCP) scenarios. With present agricultural production and management practices, N loading could increase up to 30% by the end of the 21st century under future climate scenarios, half of which would be driven by heavy precipitation. Particularly, the RCP8.5 scenario, in which heavy precipitation and drought events become more frequent, would increase N loading disproportionately to projected increases in river discharge. N loading in spring would contribute 41% and 51% of annual N loading increase under the RCP4.5 and RCP8.5 scenarios, respectively, most of which is related to higher N yield due to increases in heavy precipitation. Anthropogenic N inputs would be increasingly susceptible to leaching loss in the Midwest and the Mississippi Alluvial Plain regions. Our results imply that future climate change alone, including more frequent and intense precipitation extremes, would increase N loading and intensify the eutrophication of the Gulf of Mexico over this coming century. More effective nutrient management interventions are needed to reverse this trend.

description: A series of β-alanine substituted sulfonamide compounds (6a-6h) as juvenile hormone analogs (JHAs) has been synthesized. The structures of the synthesized compounds have been confirmed by FT-IR, 1H and 13C NMR spectroscopy and ESI-MS (high-resolution mass spectra [HRMS]) techniques. Biological screening of the synthesized analogs has been performed on the fifth larval instar of Galleria mellonella. JH activity of the compounds (6a-6h) has been tested at various concentrations and compared with commercially used JHAs pyriproxyfen (1), fenoxycarb (2). Compound N-methyl-N-phenyl-3-(p-tolylsulfonylamino)propanamide (6d) exhibited better activity among all the tested compounds with LC50 and LC90 values of 0.16 and 0.52 mg/mL, respectively. To understand the structure–activity relationship (SAR), quantum chemical descriptors have been calculated using density functional theory (DFT) method. Toxicity prediction has been performed using the absorption, distribution, metabolism, excretion and toxicity (ADMET) tool. The compounds are proposed to be nontoxic, eco-friendly and biodegradable.

description: Water stress is one of the most important limiting factors controlling terrestrial primary production, and the performance of a primary production model is largely determined by its capacity to capture environmental water stress. The algorithm that generates the global near-real-time MODIS GPP/NPP products (MOD17) uses VPD ( vapor pressure deficit) alone to estimate the environmental water stress. This paper compares the water stress calculation in the MOD17 algorithm with results simulated using a process-based biogeochemical model (Biome-BGC) to evaluate the performance of the water stress determined using the MOD17 algorithm. The investigation study areas include China and the conterminous United States because of the availability of daily meteorological observation data. Our study shows that VPD alone can capture interannual variability of the full water stress nearly over all the study areas. In wet regions, where annual precipitation is greater than 400 mm/yr, the VPD-based water stress estimate in MOD17 is adequate to explain the magnitude and variability of water stress determined from atmospheric VPD and soil water in Biome-BGC. In some dry regions, where soil water is severely limiting, MOD17 underestimates water stress, overestimates GPP, and fails to capture the intraannual variability of water stress. The MOD17 algorithm should add soil water stress to its calculations in these dry regions, thereby improving GPP estimates. Interannual variability in water stress is simpler to capture than the seasonality, but it is more difficult to capture this interannual variability in GPP. The MOD17 algorithm captures interannual and intraannual variability of both the Biome-BGC-calculated water stress and GPP better in the conterminous United States than in the strongly monsoon-controlled China.

description: Plasma sheet particles transported Earthward during times of active magnetospheric convection can interact with exospheric/thermospheric neutrals through charge exchange. The resulting Energetic Neutral Atoms (ENAs) are free to leave the influence of the magnetosphere and can be remotely detected. ENAs associated with low-altitude (300-800km) ion precipitation in the high-latitude atmosphere/ionosphere are termed low-altitude emissions (LAEs). Remotely observed LAEs are highly nonisotropic in velocity space such that the pitch angle distribution at the time of charge exchange is near 90 degrees. The Geomagnetic Emission Cone of LAEs can be mapped spatially, showing where proton energy is deposited during times of varying geomagnetic activity. In this study we present a statistical look at the correlation between LAE flux (intensity and location) and geomagnetic activity. The LAE data are from the MENA imager on the IMAGE satellite over the declining phase of solar cycle 23 (2000-2005). The SYM-H, AE, and Kp indices are used to describe geomagnetic activity. The goal of the study is to evaluate properties of LAEs in ENA images and determine if those images can be used to infer properties of ion precipitation. Results indicate a general positive correlation to LAE flux for all three indices, with the SYM-H showing the greatest sensitivity. The magnetic local time distribution of LAEs is centered about midnight and spreads with increasing activity. The invariant latitude for all indices has a slightly negative correlation. The combined results indicate LAE behavior similar to that of ion precipitation.

description: The first comparison between energy-dependent ion pitch angle distributions in the ring current deconvolved from Two Wide-angle Imagining Neutral-atom Spectrometers (TWINS) energetic neutral atom (ENA) images and measured by Time History of Events and Macroscale Interactions during Substorms (THEMIS) D and E during a magnetic storm on 29 May 2010 is shown. The ion intensities and energy spectra along the THEMIS path are also compared with those deconvolved from the TWINS ENA images. The global plots of the ion intensities show an asymmetric ring current in the early recovery phase consistent with the ASY/H index. The comparison between the in situ pitch angle distributions observed by THEMIS and those obtained here from TWINS ENA images lends credence to the global plots of pitch angle anisotropy provided by the TWINS data. The spatial dependence of the pitch angle anisotropy provides information relevant to ion precipitation and lifetimes of trapped ring current ions not available from in situ measurements.

description: [1] Images from the IMAGE satellite of precipitating protons (SU12/FUV) and trapped protons at 8.5 (MENA) and 33 keV (HENA) are compared during three periods: ( 1) 12 August 2000 from 1000 UT to 1145 UT just after the peak of a strong geomagnetic storm, ( 2) 2 June 2001 from 0100 to 0345 UT during the main phase and initial recovery of a weak storm, and ( 3) 18 June 2001 from 1400 to 1645 UT late in the recovery phase of another weak storm. Some of the features of the precipitating and trapped protons observed in these time intervals have been previously reported for other events, especially the fact that the strength of the precipitating protons and trapped protons do not always correlate. The primary new features are that ( 1) the fluxes of the precipitating protons and both the 8.5 keV and 33 keV trapped protons peak at similar magnetic latitudes and that ( 2) the peak in the 8.5 keV trapped protons is usually at the same MLT as the peak in the precipitating protons, while the peak in the 33 keV trapped protons is usually in a different MLT region than the peak of the precipitating protons. Some possible mechanisms to explain these observations are presented, but understanding this behavior should provide stringent tests for models of the Earth's inner magnetosphere.

description: An eco-friendly, highly efficient, and novel sulfonic acid functionalized imidazolium thiocyanate (Imidazole-SO3H)/SCN and sulfonic acid functionalized imidazolium chloride (Imidazole-SO3H)/Cl solid acid catalyst were successfully synthesized. The structure of catalyst was characterized by various analyses such as FT-IR, 1H NMR and 13C NMR spectroscopy. The thiocyanation reaction of various electron rich arenes such as anilines, indoles, phenols, and other aromatic compounds were selected to show the catalytic performance and efficiency of the as-prepared solid acid catalyst, and excellent yields of the corresponding aryl and heteroaryl thiocyanates derivatives were obtained under metal-free and green conditions in water. In addition, one of the important features of current method is when the thiocyanation reaction is carried out with (Imidazole-SO3H)/SCN, this reagent has a dual role in the reaction, both as thiocyanation agent and as acidic group. On the other hand, (Imidazole-SO3H)/Cl as a catalyst plays just as acidic group in reaction. The current procedure offers advantages such as metal-free and green conditions, simple procedure, the use of a commercially available reagent, simple reaction work-up, ease of separation using simple filtration, and suitable performance in the reusability of the catalyst.

This reaction exhibits broad functional group compatibility without the formation of undesired desulfonation compounds. Moreover, the procedure operates under the mild conditions avoiding the use of additional metal catalysts or potential security risk substrate (vinyl azide), and the reaction finishes in short reaction time (30 min) at room temperate.

description: The interplay between structure, magnetism and superconductivity in single crystal Ba(Fe$_{1-x}$Co$_{x}$)$_{2}$As$_{2}$ (x=0.047) has been studied using high-resolution X-ray diffraction by monitoring charge Bragg reflections in each twin domain separately. The emergence of the superconducting state is correlated with the suppression of the orthorhombic distortion around \emph{T}$_\texttt{C}$, exhibiting competition between orthorhombicity and superconductivity. Above \emph{T}$_\texttt{S}$, the in-plane charge correlation length increases with the decrease of temperature, possibly induced by nematic fluctuations in the paramagnetic tetragonal phase. Upon cooling, anomalies in the in-plane charge correlation lengths along $a$ ($ξ_{a}$) and $b$ axes ($ξ_{b}$) are observed at \emph{T}$_\texttt{S}$ and also at \emph{T}$_\texttt{N}$ indicative of strong magnetoelastic coupling. The in-plane charge correlation lengths are found to exhibit anisotropic behavior along and perpendicular to the in-plane component of stripe-type AFM wave vector (101)$_{\rm O}$ below around \emph{T}$_\texttt{N}$. The temperature dependence of the out-of-plane charge correlation length shows a single anomaly at \emph{T}$_\texttt{N}$, reflecting the connection between Fe-As distance and Fe local moment. The origin of the anisotropic in-plane charge correlation lengths $ξ_{a}$ and $ξ_{b}$ is discussed on the basis of the antiphase magnetic domains and their dynamic fluctuations.

From Hiroshima to Three-Mile-Island: Three decades of nuclear power opposition rhetoric in the United States
Creators: name: Olds, Theodore Erik
Publisher: name: University of Nevada, Las Vegas
Year: 2000

description: Rhetoric associated with the development of nuclear power in the United States was analyzed over 3-decades in order to better understand the beginnings and constituents of the rhetoric associated with anti-nuclear power perspectives. An amalgamation of existing historical/rhetorical methods utilized by Gamson and Modigliani (1989) and Darsey (1991) were employed. Progressive interpretive anti-nuclear rhetorical packages were identified for corresponding historical periods within the 34-year period. Historical periods were segmented by catalytic events, or incidents important to nuclear power development which also presented opportunities for anti-nuclear power rhetoric. The analysis reveals four individual rhetorical packages: (1) Pandora's Box; (2) Mirage; (3) Devil's Bargain; and (4) Mirage Two. The analysis further demonstrates that anti-nuclear rhetoric is progressive, synergistic, requires maintenance, relies on the unknown, and exists beyond what is reported in the media.

description: Herein we report the mild synthesis of 15 phosphonocinnamic esters by means of a solvent-free mechanically activated Horner-Wadsworth-Emmons (HWE) olefination, in regular to excellent yields (13–99%), from tetraethyl methylenediphosphonate, an aromatic or aliphatic aldehyde and potassium tert-butoxide, using 5 min of mortar and pestle grinding. Potassium tert-butoxide acts as a base and liquid-assisting grinding agent. All isolated products were fully characterized as (E)-isomers through NMR spectroscopy. Furthermore, among the synthesized compounds diethyl (E)-2-(4-methoxyphenyl)vinylphosphonate 1 was discovered as an interesting cytotoxic agent inhibiting growth of two breast cancer cell lines (MDA-MB-453, IC50 = 79 µg/mL and MCF-7 IC50 = 64 µg/mL). To the best of our knowledge, this is the first report of mechanically activated HWE reaction for the synthesis of α, β-unsaturated phosphonates and the first time some of them have been assessed as cytotoxic agents on breast cancer cell lines. In conclusion, the fast and operationally simple synthesis of (E)-phosphonocinnamic esters afforded new promising cytotoxic agents in regular to excellent yields in very short reaction times.

description: A signed graph is a graph whose edges are given (-1,+1) weights. In such a graph, the sign of a cycle is the product of the signs of its edges. A signed graph is called balanced if its adjacency matrix is similar to the adjacency matrix of an unsigned graph via conjugation by a diagonal (-1,+1) matrix. For a signed graph $Σ$ on n vertices, its exterior k-th power, where k=1,..,n-1, is a graph $\bigwedge^{k} Σ$ whose adjacency matrix is given by \[ A({$\bigwedge^{k} Σ$}) = P^{\dagger} A(Σ^{\Box k}) P, \] where P is the projector onto the anti-symmetric subspace of the k-fold tensor product space $(\mathbb{C}^{n})^{\otimes k}$ and $Σ^{\Box k}$ is the k-fold Cartesian product of $Σ$ with itself. The exterior power creates a signed graph from any graph, even unsigned. We prove sufficient and necessary conditions so that $\bigwedge^{k} Σ$ is balanced. For k=1,..,n-2, the condition is that either $Σ$ is a signed path or $Σ$ is a signed cycle that is balanced for odd k or is unbalanced for even k; for k=n-1, the condition is that each even cycle in $Σ$ is positive and each odd cycle in $Σ$ is negative.

description: Sensitive probing of temperature variations on nanometer scales represents an outstanding challenge in many areas of modern science and technology. In particular, a thermometer capable of sub-degree temperature resolution as well as integration within a living system could provide a powerful new tool for many areas of biological research, including temperature-induced control of gene expression and cell-selective treatment of disease. Here, we demonstrate a new approach to nanoscale thermometry that utilizes coherent manipulation of the electronic spin associated with nitrogen-vacancy (NV) color centers in diamond. We show the ability to detect temperature variations down to 1.8 mK (sensitivity of 9 mK/sqrt(Hz)) in an ultra-pure bulk diamond sample. Using NV centers in diamond nanocrystals (nanodiamonds), we directly measure the local thermal environment at length scales down to 200 nm. Finally, by introducing both nanodiamonds and gold nanoparticles into a single human embryonic fibroblast, we demonstrate temperature-gradient control and mapping at the sub-cellular level, enabling unique potential applications in life sciences.
Design of a fuzzy logic controller for swing-damped transport of an overhead crane payload
Creators: name: Nalley, Michael James
Publisher: name: University of Nevada, Las Vegas
Year: 2000

description: Transportation using overhead cranes can excite undesirable payload swinging. These oscillations have to be damped before other payload manipulation is done. A swing-damped motion profile based on the natural frequency of the payload is used to minimize swing excitation. In addition, a fuzzy logic controller is used to move the overhead crane along a desired path while ensuring that the payload is swing-free at the end of the motion. The control action is divided between displacement and swing controllers to simplify controller tuning for optimal performance. Examples, along with comparisons with a PD controller, are included, as well as related experimental development.

description: Our aim is to explore the nature of emission line galaxies by combining high-resolution observations obtained in different bands to understand which objects are powered by an Active Galactic Nucleus(AGN). From the spectroscopic Palomar survey of nearby bright galaxies, we selected a sample of 18 objects observed with HST, Chandra, and VLA. No connection is found between X-ray and emission line luminosities from ground-based data, unlike what is found for brighter AGN. Conversely, a strong correlation emerges when using the HST spectroscopic data, which are extracted on a much smaller aperture. This suggests that the HST data better isolate the AGN component when one is present, while ground-based line measurements are affected by diffuse emission from the host galaxies. The sample separates into two populations. The 11 objects belonging to the first class have an equivalent width of the [OIII] emission line measured from HST data EW([OIII])>~2 A and are associated with an X-ray nuclear source; in the second group we find seven galaxies with EW([OIII])

Power generation sector facing important challenges both in quality and quantity to meet the increasing requirements of consumers. Energy efficiency, reliability, economics and integration of new energy resources are important issues to enhance the stability of power system infrastructure. Optimal energy consumption scheduling minimizes the energy consumption cost and reduce the peak-to-average ratio (PAR) as well as peak load demand in peak hours. In this work, we discuss different energy consumption scheduling schemes that schedule the household appliances in real-time to achieve minimum energy consumption cost and reduce peak load curve in peak hours to shape the peak load demand.
1887 Michelson-Morley Experiment: a new analysis with computer assistance

Publisher: name: Zenodo
Year: 2022
Subjects: Michelson-Morley experiment, detection of ether, simulation of experiment

description: The captioned experiment was long in dispute for interpreting its small result compared with the expected measurement. To investigate the origin of those comparison numbers, I simulated the experiment on a computer, from which the path difference between the two arms and the lateral splits between the two coincident beams were obtained for calculating the average fringes. The zeroed results of the simulation trials and the analyzed root reason for causing such unexpected outcomes reveal the reason why the M-M experiment measured a small result of the fringe shift, and the scrutiny of its practical operation also found that the repeated manual disturbances to the working apparatus certainly brought the uncertainty of the accuracy of the original observations. Thus, this work suggests the M-M experiment to be concluded as delivering no result instead of reporting a null result, this means Newton's conception of absolute space may still be a valid proposal for the science of physics. In addition, this manuscript also provides two new ideas to detect the possible existence of absolute space—measuring the free-fall acceleration rate variation or conducting radar round-trip measurements with the proposed meliorations, see the other preprint by the same author, "Gravity's fluctuation derives from its speed—a constant to the absolute space presumed" (https://zenodo.org/deposit/7005531).

description: The hydraulic and thermal performance of microchannel heat sink configurations for high performance electronic cooling applications is investigated by numerical modelling. Conjugate heat transfer simulations are obtained through the silicon walls and the fluid domain of a square base prism heat sink traversed by 50 parallel rectangular cooling ducts, under a 150 W/cm2 constant heat flux input through the base. Al2O3 nanofluid coolant with a nanoparticle volume fraction ranging from 0 to 3% is supplied at 298 K, over the Reynolds number range 100 to 350, modelled as a single-phase homogeneous medium. Rectangular, twisted, and zig-zag fins are inserted into the plain rectangular duct to enhance the heat transfer rate. The zig-zag fin and 3% Al2O3 nanofluid provide the best thermal performance, with a 6.44 K lower average heated wall contact temperature, 60% higher Nusselt number, and 15% higher second law efficiency than without fins and plain water cooling. Twist in the microchannel fin unexpectedly reduced the microchannel pressure drop by 2% to 15% compared to a straight fin, possibly due to the more evenly distributed axial mass flux across the microchannel.

To investigate the origin of those comparison numbers, I simulated the experiment on a computer, from which the path difference between the two arms and the lateral splits between the two coincident beams were obtained for calculating the average fringes. The zeroed results of the simulation trials and the analyzed root reason for causing such unexpected outcomes reveal the reason why the M-M experiment measured a small result of the fringe shift, and the scrutiny of its practical operation also found that the repeated manual disturbances to the working apparatus certainly brought the uncertainty of the accuracy of the original observations. Thus, this work suggests the M-M experiment to be concluded as delivering no result instead of reporting a null result, this means Newton's conception of absolute space may still be a valid proposal for the science of physics. In addition, this manuscript also provides two new ideas to detect the possible existence of absolute space—measuring the free-fall acceleration rate variation or conducting radar round-trip measurements with the proposed meliorations, see the other preprint by the same author, "Gravity's fluctuation derives from its speed—a constant to the absolute space presumed" (https://doi.org/10.5281/zenodo.7034225).

description: Markov state models (MSMs) have become a popular approach for investigating the conformational dynamics of proteins and other biomolecules. MSMs are typically built from numerous molecular dynamics simulations by dividing the sampled configurations into a large number of microstates based on geometric criteria. The resulting microstate model can then be coarse-grained into a more understandable macro state model by lumping together rapidly mixing microstates into larger, metastable aggregates. However, finite sampling often results in the creation of many poorly sampled microstates. During coarse-graining, these states are mistakenly identified as being kinetically important because transitions to/from them appear to be slow. In this paper we propose a formalism based on an algebraic principle for matrix approximation, i.e. the Nystrom method, to deal with such poorly sampled microstates. Our scheme builds a hierarchy of microstates from high to low populations and progressively applies spectral clustering on sets of microstates within each level of the hierarchy. It helps spectral clustering identify metastable aggregates with highly populated microstates rather than being distracted by lowly populated states. We demonstrate the ability of this algorithm to discover the major metastable states on two model systems, the alanine dipeptide and TrpZip2.
Sequence stratigraphy and biostratigraphy of the lower member of the Deep Spring Formation: Implications for the Neoproterozoic-Cambrian boundary in the Basin and Range Province, western United States

description: The Deep Spring Formation of the southern Basin and Range Province provides information valuable in locating and correlating the Precambrian-Cambrian boundary in western North America. Sequence-stratigraphic analysis of the lower Deep Spring Formation revealed three sequence boundaries. The proposed sequence-stratigraphic model includes early highstand slumps, a feature interpreted to be unique to mixed systems, which form at the onset of the Highstand Systems Tract; This study identified the small shelly fossil Cloudina in the lower Deep Spring Formation. Cloudina was previously unrecognized at this stratigraphic level in the Basin and Range. This Neoproterozoic fossil is associated in the lower Deep Spring Formation with the shelly fossils Nevadatubulus and Sinotubulites, which traditionally are believed to be Cambrian in age. Based on the revisions to the biostratigraphy from this and other studies, the lower member is interpreted as Neoproterozoic in age and not Cambrian, as previously reported.

The zeroed results of the simulation trials and the analyzed root reason for causing such unexpected outcomes reveal the reason why the M-M experiment measured a small result of the fringe shift, and the scrutiny of its detection practice also found that the continued manual adjustments to the movable mirror certainly brought the uncertainty about the accuracy of the original observations.

description: We introduce a variant of the Banded Random Matrix ensemble and show, using detailed numerical analysis and theoretical arguments, that the phonon heat current in disordered quasi-one-dimensional lattices obeys a one-parameter scaling law. The resulting beta-function indicates that an anomalous Fourier law is applicable in the diffusive regime, while in the localization regime the heat current decays exponentially with the sample size. Our approach opens a new way to investigate the effects of Anderson localization in heat conduction, based on the powerful ideas of scaling theory.

Salts and radiation products on the surface of Europa

description: The surface of Europa could contain the compositional imprint of a underlying interior ocean, but competing hypotheses differ over whether spectral observations from the Galileo spacecraft show the signature of ocean evaporates or simply surface radiation products unrelated to the interior. Using adaptive optics at the W.M. Keck Observatory, we have obtained spatially resolved spectra of most of the disk of Europa at a spectral resolution ~40 times higher than seen by the Galileo spacecraft. These spectra show a previously undetected distinct signature of magnesium sulfate salts on Europa, but the magnesium sulfate is confined to the trailing hemisphere and spatially correlated with the presence of radiation products like sulfuric acid and SO2. On the leading, less irradiated, hemisphere, our observations rule out the presence of many of the proposed sulfate salts, but do show the presence of distorted water ice bands. Based on the association of the potential MgSO4, detection on the trailing side with other radiation products, we conclude that MgSO4 is also a radiation product, rather than a constituent of a Europa ocean brine. Based on ocean chemistry models, we hypothesize that, prior to irradiation, magnesium is primarily in the form of MgCl2, and we predict that NaCl and KCl are even more abundant, and, in fact, dominate the non-ice component of the leading hemisphere. We propose observational tests of this new hypothesis.

description: This paper deals with solution of inequality $\textbf{A}\otimes \textbf{x}\preceq \textbf{b}$, where $\textbf{A}, \textbf{x}$ and $\textbf{b}$ are interval matrices with entries defined over idempotent semiring. It deals also with the computation of a pair of intervals, ($\textbf{x},\textbf{y}$) which satisfies the equation $\textbf{A} \otimes \textbf{x}=\textbf{B}\otimes \textbf{y}$. It will be shown that this equation may be solved by considering the interval version of the iterative scheme proposed by Cuninighame-Green and Butkovic in 2003.

description: A master equation describing the evolution of averaged molecular state occupancies in molecular systems where alternation of molecular energy levels is caused by discrete dichotomous and trichotomous stochastic fields, is derived. This study is focused on the kinetics of quasi-isoenergetic transition processes in the presence of moderately high frequency stochastic field. A novel physical mechanism for temperature-independent transitions in flexible molecular systems is proposed. This mechanism becomes effective when the conformation transitions between quasi-isoenergetic molecular states take place. At room temperatures, stochastic broadening of molecular energy levels predominates the energy of low frequency vibrations accompanying the transition. This leads to a cancellation of the temperature dependence in the stochastically averaged rate constants. As examples, physical interpretations of the temperature-independent onset of P2X$_3$ receptor desensitization in neuronal membranes, as well as degradation of PER2 protein in embrionic fibroblasts, are provided.

description: This study examines elementary teacher use of district curriculum-based test results in making instructional decisions. A questionnaire was developed and distributed to elementary teachers asking about their routine practices when using test results, their comfort level in doing so, and training they have received. Returns from 944 teachers were analyzed, and it was determined some concerns exist related to the interpretation and use of test information by elementary teachers. It was concluded that teachers may need training to improve their skills in test result interpretation, and the formats used by school districts to distribute test results may need modification. In addition, twenty-five school districts were contacted and asked to share information on the models they use to communicate test information to teachers. Twelve school districts responded, and these responses were analyzed with the teacher feedback to arrive at specific recommendations regarding test result dissemination formats and schedules.

description: We present a detailed review of various Home Energy Management Schemes (HEM,s). HEM,s will increase savings, reduce peak demand and Pto Average Ratio (PAR). Among various applications of smart grid technologies, home energy management is probably the most important one to be addressed. Various steps have been taken by utilities for efficient energy consumption.New pricing schemes like Time of Use (ToU), Real Time Pricing (RTP), Critical Peak Pricing (CPP), Inclining Block Rates (IBR) etc have been been devised for future smart grids.Home appliances and/or distributed energy resources coordination (Local Generation) along with different pricing schemes leads towards efficient energy consumption. This paper addresses various communication and optimization based residential energy management schemes and different communication and networking technologies involved in these schemes.
