description: One of the primary challenges facing the Internet of Things is the reservation and efficient consumption of energy resources, especially in those types of applications that require continuous monitoring or suffer from lacking ongoing energy resources. Despite this, the indoor temperature and humidity monitoring systems are unconcerned about the insignificant amount of energy consumed during critical times when sending unimportant or useless data to the control rooms servers. This paper proposes a fuzzy logic-based approach for reducing the amount of energy spent in indoor temperature and humidity monitoring systems by filtering data that is sent to servers based on several surrounding circumstances such as time of data recording and current energy consumption amount while maintaining constant monitoring. The experimental results on the Appliances Energy Prediction dataset show that the proposed fuzzy-based approach successfully reduces energy consumption in temperature and humidity monitoring systems by 11.8% .

description: Previous studies have suggested that minoxidil stimulates growth of keratinocytes, possibly in a manner similar to the action of epidermal growth factor. Using both a short-term assay, thymidine incorporation, and a longer term assay, cell counting, to assess proliferative growth, we tested the activity of minoxidil in human keratinocyte cultures grown in 0.1 mM Ca(++). Minoxidil failed to stimulate growth in these assays. At concentrations of 5-10 micrograms per ml, minoxidil showed half-maximal inhibition of both EGF- and placental extract-stimulated thymidine incorporation. Minoxidil also inhibited proliferative growth in the presence or absence of placental extract. Direct measurement of the ability of minoxidil to compete for binding to the EGF receptor indicated that minoxidil probably does not bind to the EGF receptor. Minoxidil was not toxic, as keratinocytes continued to survive and grow, although at a slower rate, in the presence of minoxidil.

Joint calibrated estimation of inverse probability of treatment and censoring weights for marginal structural models.

description: Marginal structural models (MSMs) with inverse probability weighted estimators (IPWEs) are widely used to estimate causal effects of treatment sequences on longitudinal outcomes in the presence of time-varying confounding and dependent censoring. However, IPWEs for MSMs can be inefficient and unstable if weights are estimated by maximum likelihood. To improve the performance of IPWEs, covariate balancing weight (CBW) methods have been proposed and recently extended to MSMs. However, existing CBW methods for MSMs are inflexible for practical use because they often do not handle dependent censoring, nonbinary treatments, and longitudinal outcomes (instead of eventual outcomes at a study end). In this paper, we propose a joint calibration approach to CBW estimation for MSMs that can accommodate (1) both time-varying confounding and dependent censoring, (2) binary and nonbinary treatments, (3) eventual outcomes and longitudinal outcomes. We develop novel calibration restrictions by jointly eliminating covariate associations with both treatment assignment and censoring processes after weighting the observed data sample (i.e., to optimize covariate balance in finite samples). Two different methods are proposed to implement the calibration. Simulations show that IPWEs with calibrated weights perform better than IPWEs with weights from maximum likelihood and the "Covariate Balancing Propensity Score" method. We apply our method to a natural history study of HIV for estimating the effects of highly active antiretroviral therapy on CD4 cell counts over time.

description: We present a systematic classification of emergent particles in all 528 magnetic layer groups and 394 magnetic rod groups, which describe two-dimensional and one-dimensional crystals respectively. Our approach is via constructing a correspondence between a given magnetic layer/rod group and one of the magnetic space group, such that all irreducible representations of the layer/rod group can be derived from those of the corresponding space group. Based on these group representations, we explicitly construct the effective models for possible band degeneracies and identify all emergent particles, including both spinless and spinful cases. We find that there are six kinds of particles protected by magnetic layer groups and three kinds by magnetic rod groups. Our work provides a useful reference for the search and design of emergent particles in lower dimensional crystals.

description: Epibolin, a plasma protein, was initially purified on the basis of its ability to enhance spreading of keratinocytes. It is now known that epibolin is identical to serum spreading factor, S protein, and vitronectin, and the current name for the protein is vitronectin. Studies of vitronectin on cultured keratinocytes showed that it caused spreading and epiboly but not cellular adhesion to the substratum. In studies with other types of cells, vitronectin increased migration of several types of cells in a Boyden chamber. Because some agents that enhance spreading and adhesion, such as collagen and fibronectin, also increase motility, we tested whether vitronectin increased motility of keratinocytes. By photographing and quantitating motility of keratinocytes plated on a bed of colloidal gold particles, we determined that vitronectin increased local movement of keratinocytes in a concentration-dependent fashion, resulting in clearing of gold particles in a circular pattern around the cells, but did not cause the production of tracks found in cultures plated on collagen or fibronectin. The small increases in clearing of the gold particles that occurred in the presence of vitronectin were abolished by antibody to vitronectin. Furthermore, the marked increase in motility produced by type I collagen was significantly reduced when the keratinocytes were treated with vitronectin. Antibody to vitronectin also abrogated the vitronectin-induced reduction in collagen-stimulated motility, confirming that this action was specific for vitronectin. Serum, which contains vitronectin, stimulated motility in a fashion identical to purified vitronectin, but serum lacking vitronectin was inactive. These studies show that vitronectin causes a localized increase in movement associated with spreading resulting in a halo around individual cells, that vitronectin does not enhance directional motility of keratinocytes in this assay but in contrast antagonizes such motility produced by collagen, and that vitronectin is the factor in serum responsible for this effect. The findings with vitronectin and collagen show that these agents stimulate different types of motility. The roles in wound healing of agents stimulating different types of motility are unclear and require further study.

description: Monolayer 1T'-WTe$_2$ has been the first two-dimensional crystal where a quantum spin Hall phase was experimentally observed. In addition, recent experiments and theoretical modeling reported the presence of a robust excitonic insulating phase. While first-principles calculations with hybrid functionals and several measurements at low temperatures suggest the presence of a band gap of the order of 50 meV, experiments could confirm the presence of the helical edge states only up to 100 K. Here, we study with first-principle simulations the temperature effects on the electronic structure of monolayer 1T'-WTe$_2$ and consider the contributions of both thermal expansion and electron-phonon coupling. First, we show that thermal expansion is weak but tends to increase the indirect band gap. Then, we calculate the effect of electron-phonon coupling on the band structure with non-perturbative methods and observe a small reduction of the band inversion with increasing temperature. Notably, the topological phase and the presence of a finite gap are found to be particularly robust to thermal effects up to and above room temperature.

In-vitro testing of the influence of ethanol on the release rate of oral extended-release solid dosage forms
Creators: name: Cook, Rebecca Ann
Publisher: name: No Publisher Supplied
Year: 2007

description: There are many factors that can affect the rate of drug release from an extended-release formulation, such pH of the gastrointestinal tract and dietary intake [1]. However, there is on going concern that alcohol could also greatly affect the release rate of extended-release products. It has recently come to the FDA's attention that some extended-release oral dosage forms are comprised of drugs and/or excipients that exhibit higher solubility in ethanolic solutions than compared to water. Because of this, it can be expected that more rapid drug dissolution may occur when a patient simultaneously consumes alcohol with an extended-release product that is highly soluble in ethanol. This could potentially cause a large dose of the drug to be released at once instead of the slow steady release that was intended, posing a potential health risk to the patient [2]. Currently, there is a strong need to look at the potential of alcohol altering the drug release profile of controlled-release products. A large concern of the FDA is if there are alcohol sensitive extended-release products currently on the market. The goal of this research was to study the affect ethanol has on the release profile of four different types of extended-release formulations. Dissolution testing was conducted on the different dosage forms without ethanol to serve as the control and with various levels of ethanol to determine if the ethanol had an effect on drug release. Dissolution testing was used for the testing because of its ability to provide insight into an oral drug product's characterization and its in vivo performance [3]. High performance liquid chromatography was used as the means of analysis to determine such release rates. The affect of ethanol on the drug release profiles of Palladone® XL Capsules, Detrol® LA Capsules, Cystrin® CR Tablets and Concerta® Tablets has been studied. The drug release profiles for all the formulations were altered by the presence of ethanol in the dissolution media, especially for the Palladone® XL Capsule formulation. The extended-release function of these melt-extrusion pellets was diminished with the smallest amount of ethanol present.

description: We report the discovery of a dark companion to 2MASS J15274848+3536572 with an orbital period of 6.14 hr. Combining the radial velocity from LAMOST observations and modelling of the multiband light curve, one obtains a mass function of $\simeq 0.131~\rm M_{\odot}$, an inclination of $45.20^\circ{}^{+0.13^{\circ}}_{-0.20^{\circ}}$, and a mass ratio of $0.631^{+0.014}_{-0.003}$, which demonstrate the binary nature of the dark companion with mass of $0.98 \pm 0.03\rm M_{\odot}$ and a main-sequence K9-M0 star of $0.62 \pm 0.01~\rm M_{\odot}$. LAMOST optical spectra at a range of orbital phases reveal extra-peaked Halpha emission that suggests the presence of an accretion disk. The dark companion does not seem to be a white dwarf because of the lack of any observed dwarf nova outbursts in the long-term data archive, although a magnetic white dwarf cannot be excluded. Alternatively, we propose a scenario wherein the dark companion is a neutron star, but we have not detected radio pulsations or a single pulse from the system with the FAST (Five-hundred-meter Aperture Spherical radio Telescope), which hints at a radio-quiet compact object. If the dark companion is identified as a neutron star, it will be the nearest ( ~ 118 pc) and lightest neutron star. Furthermore, a kinematic analysis of the system's orbit in the galaxy may suggest its supernova event is associated with the radionuclide $^{60} \rm Fe$ signal observed from the deep-sea crusts. This radio-quiet and X-ray-dim nearby neutron star may resemble an XDINS (X-ray-dim isolated neutron star), but in a binary.

description: Type VII collagen (C7) is a stratified squamous epithelial basement membrane protein composed of three identical alpha chains, each consisting of a 145-kDa amino-terminal noncollagenous (NC1) domain and a 145-kDa carboxyl-terminal collagenous domain. Morphologic and biochemical studies have shown that tissue-specific aggregates of C7 dimers called anchoring fibrils may contribute to epithelial basement membrane organization and adherence by interacting with extracellular matrix (ECM) proteins such as type IV collagen. In this study, we cloned a cDNA encoding most of the NC1 domain of C7. The deduced amino acid sequence revealed motifs characteristic of multidomain ECM proteins that contribute to the tissue-specific organization of ECM including a region of 7 1/2 sequential fibronectin type III (Fn III) homology repeats, a potential collagen-binding region homologous to the A domain of von Willebrand factor (vWf) and an RGD sequence. A purified C7 fusion protein containing these motifs specifically bound to type IV collagen in a functional assay. These results suggest that regions within the NC1 domain of C7 mediate interactions with lamina densa and dermal ECM proteins including type IV collagen. Structural mutations and autoepitopes in these regions may represent mechanisms for the development of defective basement membrane organization and adherence in genetic and autoimmune forms of epidermolysis bullosa.

description: The renormalization of iterated one-pion exchange (OPE) has been studied in Chiral Effective Field Theory ($χ$EFT) for the antinucleon-nucleon ($\overline{N}\!N$) scattering in some partial waves (Phys. Rev. C 105, 054005 (2022)). We go further for the other higher partial waves but with total angular momenta $J\leq 3$ in this paper. Contact interactions are represented by a complex spherical well in coordinate space. Changing the radius of the spherical well means changing the cutoff. We check the cutoff dependence of the phase shifts, inelasticities, and mixing angles for the partial waves, and show that contact interactions are needed at leading order in channels where the singular tensor potentials of OPE are attractive. Results are compared with the energy-dependent partial-wave analysis of $\overline{N}\!N$ scattering data. Comparisons between our conclusions and applications of $χ$EFT to the nucleon-nucleon system are discussed as well.

description: We analyze the performance of the Borda counting algorithm in a non-parametric model. The algorithm needs to utilize probabilistic rankings of the items within $m$-sized subsets to accurately determine which items are the overall top-$k$ items in a total of $n$ items. The Borda counting algorithm simply counts the cumulative scores for each item from these partial ranking observations. This generalizes a previous work of a similar nature by Shah et al. using probabilistic pairwise comparison data. The performance of the Borda counting algorithm critically depends on the associated score separation $Δ_k$ between the $k$-th item and the $(k+1)$-th item. Specifically, we show that if $Δ_k$ is greater than certain value, then the top-$k$ items selected by the algorithm is asymptotically accurate almost surely; if $Δ_k$ is below certain value, then the result will be inaccurate with a constant probability. In the special case of $m=2$, i.e., pairwise comparison, the resultant bound is tighter than that given by Shah et al., leading to a reduced gap between the error probability upper and lower bounds. These results are further extended to the approximate top-$k$ selection setting. Numerical experiments demonstrate the effectiveness and accuracy of the Borda counting algorithm, compared with the spectral MLE-based algorithm, particularly when the data does not necessarily follow an assumed parametric model.

description: Acoustic modes of oscillation are affected by stellar activity, however it is unclear how starspots contribute to these changes. Here we investigate the nonmagnetic effects of starspots on global modes with angular degree $\ell \leq 2$ in highly active stars, and characterize the spot seismic signature on synthetic light curves. We perform 3D time-domain simulations of linear acoustic waves to study their interaction with a model starspot. We model the spot as a 3D change in the sound speed stratification with respect to a convectively stable stellar background, built from solar Model S. We perform a parametric study by considering different depths and perturbation amplitudes. Exact numerical simulations allow the investigation of the wavefield-spot interaction beyond first order perturbation theory. The interaction of the axisymmetric modes with the starspot is strongly nonlinear. As mode frequency increases, the frequency shifts for radial modes exceed the value predicted by linear theory, while the shifts for the $\ell=2, m=0$ modes are smaller than predicted by linear theory, with avoided-crossing-like patterns forming between the $m=0$ and $m=1$ mode frequencies. The nonlinear behavior increases with increasing spot amplitude and/or decreasing depth. Linear theory still reproduces the correct shifts for nonaxisymmetric modes. In the nonlinear regime the mode eigenfunctions are not pure spherical harmonics, but rather a mixture of different spherical harmonics. This mode mixing, together with the frequency changes, may lead to misidentification of the modes in the observed acoustic power spectra.

description: Combining Global Navigation Satellite System (GNSS) with visual and inertial sensors can give smooth pose estimation without drifting. The fusion system gradually degrades to Visual-Inertial Odometry (VIO) with the number of satellites decreasing, which guarantees robust global navigation in GNSS unfriendly environments. In this letter, we propose an open-sourced invariant filter-based platform, InGVIO, to tightly fuse monocular/stereo visual-inertial measurements, along with raw data from GNSS. InGVIO gives highly competitive results in terms of computational load compared to current graph-based algorithms, meanwhile possessing the same or even better level of accuracy. Thanks to our proposed marginalization strategies, the baseline for triangulation is large although only a few cloned poses are kept. Moreover, we define the infinitesimal symmetries of the system and exploit the various structures of its symmetry group, being different from the total symmetries of the VIO case, which elegantly gives results for the pattern of degenerate motions and the structure of unobservable subspaces. We prove that the properly-chosen invariant error is still compatible with all possible symmetry group structures of InGVIO and has intrinsic consistency properties. Besides, InGVIO has strictly linear error propagation without linearization error. InGVIO is tested on both open datasets and our proposed fixed-wing datasets with variable levels of difficulty and various numbers of satellites. The latter datasets, to the best of our knowledge, are the first datasets open-sourced to the community on a fixed-wing aircraft with raw GNSS.

description: We study the interaction of an electron/hole with inhomogeneous magnetic field in the presence of a screw dislocation. We consider the internal structure of the defect, i.e., we consider the core that gives rise to a finite size to the defect. In addition, we assume that this core determines a forbidden region for the electron/hole. Then, we solve the Schrödinger equation and show that an Aharonov-Bohm-type effect arises from the influence of the topological defect and the missing magnetic flux on the eigenvalues of energy.

description: Trichohyalin, a protein of Mr between 190 and 220 kDa in different species, was first demonstrated in large granules of the inner root sheath and medulla of hair follicles and may provide a matrix for keratin filaments. We have purified trichohyalin in milligram quantities from a citric acid-insoluble fraction derived from pig tongue epithelium. Trichohyalin was extracted under conditions of low ionic strength from the citric acid-insoluble fraction, separated by gel-filtration chromatography in buffer containing 1 M NaBr, and concentrated by ion-exchange chromatography in buffer containing 4 M urea. The purified material, which is soluble in buffers containing 1 M NaBr, was considered to be trichohyalin because of its characteristic molecular weight and amino acid composition and its localization to hair follicle inner root sheath and medulla by indirect immunofluorescence using antibodies against the purified protein. Immunofluorescence showed that trichohyalin is a major protein of filiform papillae of the tongue. Unlike trichohyalin from other animals examined, the porcine protein is a doublet on SDS polyacrylamide gels of 195 and 210 kDa; both bands are recognized by different antibodies, their two-dimensional peptide maps are nearly identical, and they have nearly identical isoelectric points of about 6.6. Trichohyalin has a Stokes radius of 124 A on gel filtration and a Svedberg constant of 6, consistent with an extended structure. The protein probably associates reversibly in solution, and the native protein we have isolated may be dimeric, because crosslinking of the iodinated purified protein with disuccinimidyl suberate demonstrated the presence of a dimer, which could be dissociated in the presence of high concentrations of urea. Rotary shadowing electron microscopy of the native protein showed a filamentous structure averaging 85 nm in length with a single globular-appearing end-domain. The purification of native trichohyalin provides a basis for future functional studies.

description: Since launch in 2008, the Fermi Gamma-ray Burst Monitor (GBM) has detected many hundreds of bursts from magnetar sources. While the vast majority of these bursts have been attributed to several known magnetars, there is also a small sample of magnetar-like bursts of unknown origin. Here we present the Fermi/GBM magnetar catalog, giving the results of the temporal and spectral analyses of 440 magnetar bursts with high temporal and spectral resolution. This catalog covers the first five years of GBM magnetar observations, from July 2008 to June 2013. We provide durations, spectral parameters for various models, fluences and peak fluxes for all the bursts, as well as a detailed temporal analysis for SGR J1550-5418 bursts. Finally, we suggest that some of the bursts of unknown origin are associated with the newly discovered magnetar 3XMM J185246.6+0033.7.

description: S. sesban is mainly used as economical purpose and S. grandiflora is known for medicinal as well as economical. Chemical characterization and antidiabetic activity of seed extracts were not explored yet. Seeds of S. sesban and S. grandiflora were separated in seed coat, germ, and endosperm by domestic grinder mixer. Successive soxhlet extraction of separated parts of Sesbania seed were carried out. Chemical profiling of methanolic extract was carried out by GC-MS, HPLC, and in vitro alpha amylase inhibitory assay. D-pinitol was found to be maximum (48.39%) in seed coat and minimum in seed (8.35%) of methanolic extracts of Sesbania seed. Alpha-amylase inhibitory activity of methanolic extracts of different parts were also studied in which DSSh, DSSp, & DSSe showed similar IC50 to acarbose, antidiabetic drugs. The result showed that S. sesban and S. grandiflora seed and endosperm is rich in health promoting mineral like Na (241 mg/100 gm and 238 mg/100 gm), K (103.1 mg/100 gm) and (60.2 mg/100 gm), Ca (525 mg/100 gm) and (500 mg/100 gm) and Fe (67.5 and 91.9 mg/100 gm). Hence, it is similar to some edible legumes which possess bioactive compound with therapeutic value and can be efficiently explored for the development of new functional or nutraceutically valued food products.

description: In a model of spontaneous scalarization of neutron stars proposed by Damour and Esposite-Farese, a general relativistic branch becomes unstable to trigger tachyonic growth of a scalar field $ϕ$ toward a scalarized branch. Applying this scenario to cosmology, there is fatal tachyonic instability of $ϕ$ during inflation and matter dominance being incompatible with solar-system constraints on today's field value $ϕ_0$. In the presence of a four-point coupling $g^2 ϕ^2 χ^2/2$ between $ϕ$ and an inflaton field $χ$, it was argued by Anson et al. that a positive mass squared heavier than the square of a Hubble expansion rate leads to the exponential suppression of $ϕ$ during inflation and that $ϕ_0$ can remain small even with the growth of $ϕ$ after the radiation-dominated epoch. For several inflaton potentials approximated as $V(χ)=m^2 χ^2/2$ about the potential minimum, we study the dynamics of $ϕ$ during reheating as well as other cosmological epochs in detail. For certain ranges of the coupling $g$, the homogeneous field $ϕ$ can be amplified by parametric resonance during a coherent oscillation of the inflaton. Incorporating the backreaction of created particles under a Hartree approximation, the maximum values of $ϕ$ reached during preheating are significantly smaller than those obtained without the backreaction. We also find that the minimum values of $g$ consistent with solar system bounds on $ϕ$ at the end of reheating are of order $10^{-5}$ and hence there is a wide range of acceptable values of $g$. Thus, the scenario proposed by Anson et al. naturally leads to the viable cosmological evolution of $ϕ$ consistent with local gravity constraints, without modifying the property of scalarized neutron stars.

description: Com este artigo pretende-se analisar alguns vídeos relacionados com o Teorema de Pitágoras, segundo três perspetivas: conteúdo do vídeo, conteúdo e quantidade dos comentários e análise da relação vídeo e comentário. Tal análise é efetuada em três momentos: no primeiro momento a análise do conteúdo do vídeo em termos de rigor científico oral e escrito e da sua qualidade; no segundo momento a quantidade dos comentários positivos e/ou negativos, dos comentários através do “gosto” e “não gosto”; por último, análise da relação dos comentários com o visionamento/conteúdo do vídeo. Os vídeos analisados encontram-se no YouTube. Relativamente ao procedimento metodológico para a recolha de dados, a análise baseou-se na definição de expressões de pesquisa, critérios de inclusão e pela análise da quantidade e qualidade dos comentários registados pelos utilizadores. Na análise realizada emergem alguns resultados indicadores de que os vídeos mais visionados e comentados, não ganham esta preferência pelo seu rigor científico.

title: Public perceptions of the risk and social acceptability of driving under the influence of cannabis
Creators: name: Pollard, Megan Ashley
Publisher: name: Memorial University of Newfoundland

description: Aside from alcohol, cannabis is the most commonly used substance amongst Canadians, especially those aged 18-24. A prominent risk associated with cannabis use is driving under the influence. Cannabis impairs key motor abilities and executive functions necessary for driving and increases the likelihood of being involved in a fatal accident. Despite this, many people believe that driving under the influence of cannabis is safe, particularly compared to driving under the influence of alcohol. Utilizing an experimental vignette design, the primary purpose of the current study was to examine public opinions about the dangerousness and social acceptability of driving under the influence of cannabis compared to alcohol or driving while tired. An additional aim was to determine how attitudes differed based on the sex of the driver. Participants (N=453) between the ages of 18 and 65 completed an online survey in which they were randomly assigned to one of six vignettes describing a 22-year-old driving under the influence. Participants then answered six questions about the dangerousness and social acceptability of the behavior described. A series of ANOVAs revealed a significant main effect of substance use across items. A significant main effect of sex was found on a measure of social acceptability. Post hoc tests revealed that driving under the influence of cannabis was considered less dangerous and more socially acceptable than driving under the influence of alcohol. Additionally, it was considered more socially acceptable for a female to drive while impaired than a male. Overall, these findings highlight the misconceptions that exist about the harms associated with cannabis use and have implications for the importance of awareness campaigns to educate about cannabis and driving.
Automated design process of sustainable industrial packaging

description: Sustainability and environmentology are becoming important issues because the natural resources have been heavily consumed in the past century and major parts of them have been wasted on some one-time-use type of applications such as packaging. As an engineer, and more basically as a resident of our only earth, one is obligated to preserve the natural resources for the coming generations. One should not selfishly consume the limited natural resources found on the earth but should use these with appreciation of what we have been given. Designs for sustainability and environmentology in industrial packaging are studied in this research by means of reducing unnecessary usage of material, increase structure strength under limited amount of material and replacing plastics with environmentally friendly materials. These ideas are accomplished by incorporating some design concepts on generating new packaging structures. These designs include design of the core structures of sandwich board, design of supporting tray efficiently, and design of molded pulp with better reinforcements. Topology optimization of packaging structures utilizing environmental friendly materials is also studied in this dissertation to determine a set of packaging with less material while strength of the packaging structure is optimized; and less pollution and impact on the environment is accomplished.The main contributions of this dissertation are: (1) Design toward sustainability and environmentology, (2) Developed a simple topology optimization scheme that provides valid results to design spaces with non-uniform element volume, (3) Development of automatic and efficient mold design algorithm for general supporting packaging, (4) Application of topology optimization to the design of industrial packaging, and (5) Development of systematic design process of designing molded pulp.
