description: Starch based scaffolds are considered as promising biomaterials for bone tissue engineering. In this study, a highly porous starch/polyvinyl alcohol (PVA) based nanocomposite scaffold with a gradient pore structure was made by incorporating different bio-additives, including citric acid, cellulose nanofibers, and hydroxyapatite (HA) nanoparticles. The scaffold was prepared by employing unidirectional and cryogenic freeze-casting and subsequently freeze-drying methods. Fourier transform infrared (FTIR) spectroscopy confirmed the cross-linking of starch and PVA molecules through multiple esterification phenomenon in presence of citric acid as a cross-linking agent. Field emission scanning electron microscopy (FE-SEM) observations showed formation of aligned lamellar pores with a gradient pore width in the range of 80 to 292 um, which well meets the pore size requirement for bone regeneration, and also well dispersion of cellulose and HA nanofillers within the scaffold matrix. Based on the mechanical testing results, the cellulose-HA reinforced scaffold possesses sufficient compressive modulus and yield strength for non-load bearing applications in the dry state; and also it presents fast responsive shape recovery in the wet state. According to in-vitro assessments, apatite phase mineralization was extensively induced in the presence of HA nanoparticles as heterogeneous nucleating sites. Also, it was revealed that cellulose and HA nanofillers decelerate and accelerate the scaffold biodegradation rate, respectively. MTT assay proved good cytocompatibility of the nanocomposite scaffold with osteoblast cells. Finally, it was shown that the introduced scaffold provides a suitable platform for the cells adhesion.

description: We present a dedicated experimental setup which is currently used to search for long lived super heavy elements (SHE) implanted in catcher scintillators which were irradiated by reaction products of $^{197}$Au (7.5 A.MeV) projectile and $^{232}$Th target collisions during our experiment performed at Cyclotrone Institute, Texas A$\&$M University in 2015. The built-in novel measuring apparatus consists of $Δ$E-E detector pairs which are able to register $α$ or spontaneous fission (SF) decays of heavy reaction products deposited in the scintillators. Their unique feature is that the examined scintillators are at the same time $Δ$E part of each of $Δ$E-E detector while E part is a silicon detector. Our apparatus is dedicated to search for SHEs which have a lifetime of a year till tens of years. Results of commissioning tests of our setup are presented.

description: Using Monte Carlo simulation, we studied the electrical conductance of two-dimensional films. The films consisted of a poorly conductive host matrix and highly conductive rodlike fillers (rods). The rods were of various lengths, obeying a log-normal distribution. They were allowed to be aligned along a given direction. The impacts of length dispersity and the extent of rod alignment on the insulator-to-conductor phase transition were studied. Two alternative computational approaches were compared. Within Model I, the films were transformed into resistor networks with regular structures and randomly distributed conductances. Within Model II, the films were transformed into resistor networks with irregular structures but with equal conductivities of the conductors. Comparison of the models evidenced similar behavior in both models when the concentration of fillers exceeded the percolation threshold. Some analytical results were obtained: (i) the relationship between the number of fillers per unit area and the transmittance of the film within Model I, (ii) the electrical conductance of the film for dense networks within Model II.

description: In the context of field theory two elements seem to be necessary to search for strong-weak coupling duality. First, a gauge theory formulation and second, supersymmetry. For gravitation these two elements are present in MacDowell-Mansouri supergravity. The search for an "effective duality" in this theory presents technical and conceptual problems that we discuss. Nevertheless, by means of a field theoretical approach, which in the abelian case coincides with $S$-duality, we exhibit a dual theory, with inverted couplings. This results in a supersymmetric non-linear sigma model of the Freedman-Townsend type.

description: This work deals with intersection points: conjugate points and cut points, of timelike geodesics emanating from a common initial point in special spacetimes. The paper contains three results. First, it is shown that radial timelike geodesics in static spherically symmetric spacetimes are globally maximal (have no cut points) in adequate domains. Second, in one of ultrastatic spherically symmetric spacetimes, Morris--Thorne wormhole, it is found which geodesics have cut points (and these must coincide with conjugate points) and which ones are globally maximal on their entire segments. This result, concerning all timelike geodesics of the wormhole, is the core of the work. The third outcome deals with the astonishing feature of all ultrastatic spacetimes: they provide a coordinate system which faithfully imitates the dynamical properties of the inertial reference frame. We precisely formulate these similarities.

subject: Philosophy and religious studies

description: The architectural study aims to investigate the mosque identity in Qatar from two different time perspectives, the past, and the present. Through qualitative and field exploration methods, it will also study the history of design approaches for Mosque architecture in Qatar. Moreover, through extensive research on the different styles of existing Mosques in the region, the research will analyze past design approaches and the evolution of mosque architecture across the country, in both residential and commercial zones. This will in turn define the impact of traditional, contemporary and western non-Muslim styles on the architecture of mosques in Qatar. With a focus on the national vision, this research will study the mosques in Qatar as a religious typology, the significance of mosques in the Qatari society by then, and the advancement of the style and design of mosques from the 17th century. Additionally, it aims to pave the way by connecting the old and the new by conducting case studies of five mosques from different time periods to compensate for the lack of literature by generating architectural surveys.

description: New experimental data for the $^{38}$Ar($α$,n)$^{41}$Ca and $^{38}$Ar($α$,p)$^{41}$K reactions were used to find a best-fit set of parameters for statistical model calculations. The very good agreement between the experimental data and the best-fit calculation confirms the applicability of the statistical model for nuclei in the vicinity of the doubly-magic $^{40}$Ca despite of their relatively low level densities. The present study investigates the sensitivities and finds that the $α$-nucleus and the nucleon-nucleus potentials are the most important ingredients for the calculation of ($α$,n) and ($α$,p) reactions in the statistical model. Furthermore, the width fluctuation correction plays an essential role in the peculiar case of $^{38}$Ar. The best-fit parameters from $^{38}$Ar are applied to the mirror nucleus $^{38}$Ca and the neighboring $^{36}$Ar and $^{40}$Ar nuclei. For $^{38}$Ca this results in an astrophysical reaction rate of the $^{38}$Ca($α$,p)$^{41}$Sc reaction which has a flatter temperature dependence compared to all previous calculations. For $^{40}$Ar a better reproduction of $^{40}$Ar($α$,p)$^{43}$K data from literature is obtained. The disagreement between calculation and an early experimental data point for the $^{36}$Ar($α$,p)$^{39}$K reaction persists.

Electrical percolation in metal wire network based strain sensors
Creators: name: Kumar, Ankush

Year: 2019
Subjects: subject: Applied Physics (physics.app-ph)
subject: FOS: Physical sciences

description: Metal wire networks rely on percolation paths for electrical conduction, and by suitably introducing break-make junctions on a flexible platform, a network can be made to serve as a resistive strain sensor. Several experimental designs have been proposed using networks made of silver nanowires, carbon nanotubes and metal meshes with high sensitivities. However, there is limited theoretical understanding; the reported studies have taken the numerical approach and only consider rearrangement of nanowires with strain, while the critical break-make property of the sensor observed experimentally has largely been ignored. Herein, we propose a generic geometrical based model and study distortion, including the break-make aspect, and change in electrical percolation of the network on applying strain. The result shows that when a given strain is applied, wire segments below a critical angle with respect to the applied strain direction end up breaking, leading to increased resistance of the network. The percolation shows interesting attributes; the calculated resistance increases linearly in the beginning and at a higher rate for higher strains, consistent with the experimental findings. In a real scenario, the strain direction need not necessarily be in the direction of measurement, and therefore, strain value and its direction both are incorporated into the treatment. The study reveals interesting anisotropic conduction features; strain sensitivity is higher parallel to the strain, while strain range is wider for perpendicular measurement. The percolation is also investigated on direct microscopic images of metal networks to obtain resistance-strain characteristics and identification of current percolation pathways. The findings will be important for electrical percolation in general, particularly in predicting characteristics and improvising metal network-based strain sensors.

Progress in Establishing a Connection Between the Electromagnetic Zero-Point Field and Inertia

description: We report on the progress of a NASA-funded study being carried out at the Lockheed Martin Advanced Technology Center in Palo Alto and the California State University in Long Beach to investigate the proposed link between the zero-point field of the quantum vacuum and inertia. It is well known that an accelerating observer will experience a bath of radiation resulting from the quantum vacuum which mimics that of a heat bath, the so-called Davies-Unruh effect. We have further analyzed this problem of an accelerated object moving through the vacuum and have shown that the zero-point field will yield a non-zero Poynting vector to an accelerating observer. Scattering of this radiation by the quarks and electrons constituting matter would result in an acceleration-dependent reaction force that would appear to be the origin of inertia of matter (Rueda and Haisch 1998a, 1998b). In the subrelativistic case this inertia reaction force is exactly newtonian and in the relativistic case it exactly reproduces the well known relativistic extension of Newton's Law. This analysis demonstrates then that both the ordinary, F=ma, and the relativistic forms of Newton's equation of motion may be derived from Maxwell's equations as applied to the electromagnetic zero-point field. We expect to be able to extend this analysis in the future to more general versions of the quantum vacuum than just the electromagnetic one discussed herein.

description: A generic prediction of inflation is that the thermalized region we inhabit is spatially infinite. Thus, it contains an infinite number of regions of the same size as our observable universe, which we shall denote as $Ø$-regions. We argue that the number of possible histories which may take place inside of an $Ø$-region, from the time of recombination up to the present time, is finite. Hence, there are an infinite number of $Ø$-regions with identical histories up to the present, but which need not be identical in the future. Moreover, all histories which are not forbidden by conservation laws will occur in a finite fraction of all $Ø$-regions. The ensemble of $Ø$-regions is reminiscent of the ensemble of universes in the many-world picture of quantum mechanics. An important difference, however, is that other $Ø$-regions are unquestionably real.

description: Neonatal respiratory distress syndrome (NRDS) is a common complication of gestational diabetes mellitus (GDM) and late preterm births. Research suggests that SIRT1 was involved in LPS-induced acute respiratory distress syndrome, but its mechanism remains to be further explored. Here, pregnant rats were intraperitoneally injected with 45 mg/Kg streptozotocin at day 0 of gestation to induce GDM and injected with LPS at day 17 of gestation to induce late preterm birth. Pioglitazone (a PPARγ agonist) was administered from day 17 to parturition in GDM group, and it was administered for 3 days before LPS injection in late preterm birth group. SRT1720 (a SIRT1 activator) was administered by oral gavage from day 0 to day 17 in both groups. Our data showed that activation of SIRT1 or PPARγ alleviated the abnormal blood glucose metabolism and lung tissue injury, downregulated expression of surfactant proteins (SP-B and SP-C), and decreased activation of the PI3K/AKT pathway induced by GDM and late preterm birth in neonatal rats. Moreover, an insulin resistance model was established by treating primary AT-II cells with insulin. Activation of SIRT1 reversed insulin-induced reduction in cell proliferation, glucose consumption, SP-B and SP-C expression, and the activity of the PI3K/AKT pathway and increase in cellular inflammation and apoptosis. Mechanistically, SIRT1 upregulated PPARγ expression via deacetylation of QKI5, an RNA binding protein that can stabilize its target mRNA molecules, and then activated the PI3K/AKT pathway. In conclusion, SIRT1 promotes the expression of PPARγ via upregulation of QKI5 and activates the PI3K/AKT pathway, thus mitigating NRDS caused by GDM and late preterm birth.

Dynamical integrals are constructed from spacetime symmetry related to $sl(2.{\bf R})$ algebra. Mass-shell condition restricts dynamical integrals to a cone (without vertex) which defines physical-phase space. We parametrize the cone by canonical coordinates. Canonical quantization with definite choice of operator ordering leads to unitary irreducible representations of $SO_\uparrow (2.1)$ group.

description: Network modeling of high-dimensional time series data is a key learning task due to its widespread use in a number of application areas, including macroeconomics, finance and neuroscience. While the problem of sparse modeling based on vector autoregressive models (VAR) has been investigated in depth in the literature, more complex network structures that involve low rank and group sparse components have received considerably less attention, despite their presence in data. Failure to account for low-rank structures results in spurious connectivity among the observed time series, which may lead practitioners to draw incorrect conclusions about pertinent scientific or policy questions. In order to accurately estimate a network of Granger causal interactions after accounting for latent effects, we introduce a novel approach for estimating low-rank and structured sparse high-dimensional VAR models. We introduce a regularized framework involving a combination of nuclear norm and lasso (or group lasso) penalty. Further, and subsequently establish non-asymptotic upper bounds on the estimation error rates of the low-rank and the structured sparse components. We also introduce a fast estimation algorithm and finally demonstrate the performance of the proposed modeling framework over standard sparse VAR estimates through numerical experiments on synthetic and real data.

description: The main goal of the ROMSOC project is to develop new modelling, simulation and optimization (MSO) techniques
 and associated software to handle real-world scenarios which are relevant for industrial applications in
 different application areas. The required full order models (FOM) involve coupled multiphysics problems for
 which standard numerical methods used to compute accurate approximated solutions demand high computational
 costs and usually fail to provide real-time simulation tools. Hence, the use of reduced order models
 (ROM) is a must for the design of computational tools, which are potentially applicable in real-world industrial
 problems. The report briefly describes ROM approaches for specific applications developed within the projects
 of ESR1, ESR6, ESR8 and ESR10.

description: Meaningful analysis of next-generation sequencing (NGS) data, extensively produced by genomics studies, relies largely on the accuracy and consistency of the genome variants and genotypes. Hence, a systematic comparison of the variant callers could give crucial outputs in any NGS-based genomics experiment. Although several tools are available for variant calling, accuracy of these tools and their interpretation in different perspectives are not fully reliable. Therefore, A systematic comparison of the variant callers could provide important outcomes in any structural genomics experiment. The assessment of several commonly used tools has also shown that a single tool cannot meet all these requirements. Additional experiments and extensive manual work are required to identify false positive and false negative variants. To overcome the situation we devised a smart combination and output filtration by using available open source pipeline. We proposed a ZAMS pipeline, which is an automatic pipeline for calling single nucleotide polymorphisms and short indels, using a new artefact and polymorphism score and combining and filtering the output of three open source variant calling pipeline. This pipeline reduces false positive as well as false negative variants through a combination of these three tools output results.
Interference of barley host cell death signaling by powdery mildew AVR-A effectors

description: Plants have evolved a variety of immune mechanisms, including a localized host cell death, to defend against microbes. Localized plant cell death is thought to be particularly effective against the spread of biotrophic plant pathogens, which rely on living host cells for proliferation. More recently, small nucleotide-based molecules were shown to be central regulators in immune-related cell death and resistance. The obligate biotrophic fungus Blumeria graminis f. sp. hordei (Bgh) causes the powdery mildew disease on barley leaves. During host infection, Bgh secrets hundreds of effectors, including the so-called AVRA effectors, which are catalytically inactive RNase-like proteins. AVRA effectors likely interfere with host cell death and immune signaling to promote Bgh virulence. One hypothesis is that that AVRA effectors target immune-related nucleotide-based molecules. To test our hypotheses, we transiently expressed AVRA effectors in barley protoplasts and treated the cells with several known cell death inducers to determine inhibition of cell death by the fungal effectors. We relied on a similar approach in stably transformed Arabidopsis thaliana to determine the conservation of cell death and effector function between monocots and dicots. As a first step, we could establish assays to quantitatively measure the cell death mediated by 2′-deoxyadenosine (dAdo), Bcl-2 associated X-protein (BAX), and the TIR domain of Recognition of Peronospora parasitica 1 (RPP1-TIR) in barley protoplasts.  Additionally, we demonstrated that the two Bgh effectors, AVRA7-1 and AVRA13-1, attenuate the dAdo-mediated cell death response of barley protoplasts. Furthermore, stable transgenic A. thaliana expressing AVRa13-1 are less sensitive to dAdo treatment, indicating that the effector function is conserved between monocots and dicots. In the future, we will investigate whether the cell death inhibition is specific to AVRA7-1 and AVRA13-1 and if these results can be repeated in Nicotiana benthamiana.

The maximum number g_N of consecutive levels exhibiting the universal Wigner-Dyson rigidity (the Thouless number) is given as a function of the strength U of the interaction for the bulk of the spectrum. In the dilute limit, one finds two thresholds: When U

description: In a recent paper (gr-qc/9903081) Choptuik, Hirschmann, and Marsa have discovered the scaling law for the lifetime of an intermediate attractor in the formation of n=1 colored black holes via fine tuning. We show that their result is in agreement with the prediction of linear perturbation analysis. We also briefly comment on the dependence of the mass gap across the threshold on the radius of the event horizon.

The Sachs-Wolfe Effect: Gauge Independence and a General Expression

description: In this paper we address two points concerning the Sachs-Wolfe effect: (i) the gauge independence of the observable temperature anisotropy, and (ii) a gauge-invariant expression of the effect considering the most general situation of hydrodynamic perturbations. The first result follows because the gauge transformation of the temperature fluctuation at the observation event only contributes to the isotropic temperature change which, in practice, is absorbed into the definition of the background temperature. Thus, we proceed without fixing the gauge condition, and express the Sachs-Wolfe effect using the gauge-invariant variables.

CO luminosity-Linewidth correlation of low and high redshift galaxies and its possible cosmological utilization

description: A linear correlation has been proposed between the CO luminosity ($\rm{L}^{\prime}_{\rm{CO}}$) and full-width at half maximum (FWHM) for high-redshift (z > 1) submillimeter galaxies. However, the controversy concerning the $\rm{L}^{\prime}_{\rm{CO}}$-FWHM correlation seems to have been caused by the use of heterogeneous samples (e.g., different transition lines) and/or data with large measurement uncertainties. In order to avoid the uncertainty caused by using different rotational transitions, in this work we make an extensive effort to select only CO($J = 1-0$) data from the literature. We separate these wide-ranging redshift data into two samples : the low-redshift (z < 1) and high-redshift (z > 1) samples. The samples are corrected for lensing magnification factors if gravitational-lensing effects appeared in the observations. The correlation analysis shows that there exists significant $\rm{L}^{\prime}_{\rm{CO}}$-FWHM correlations for both the low-redshift and high-redshift samples. A comparison of the low- and high-redshift $\rm{L}^{\prime}_{\rm{CO}}$-FWHM correlations does not show strong evolution with redshift. Assuming that there is no evolution, we can use this relation to determine the model independent distances of high-redshift galaxies. We then constrain cosmological models with the calibrated high-redshift CO data and the sample of Type Ia supernovae in the Union 2.1 compilation. In the constraint for wCDM with our samples, the derived values are w_{0} = -1.02 {\pm} 0.17, Ω_{m0} = 0.30{\pm}0.02, and H_{0} = 70.00 {\pm}0.60 km\,s^{-1}\,Mpc^{-1}.

Trademark Applications in Italian Regions
Creators: name: Leogrande, Angelo
Publisher: name: Zenodo
Year: 2024

description: Trademark applications in Italian regions have grown on average by 32.35% between 2018 and 2023. The European Innovation Scoreboard (EIS) calculates trademark applications per billion of GDP in Italian regions. The data consist of a ratio between the number of trademark applications filed with the European Union Intellectual Property Office (EUIPO) and the Gross Domestic Product in Purchasing Power Standards. Trademarks are an important indicator of innovation, especially for the service sector. The EU trademark grants its holder a uniform right applicable in all member states of the European Union through a single procedure that simplifies trademark policy at the European level. It fulfills the three essential functions of a trademark it identifies the origin of goods and services, guarantees consistent quality through the company’s commitment to consumers, and serves as a form of communication, a basis for advertising and publicity. The data are available for the 20 Italian regions between 2018 and 2023.

description: Aortic and carotid stiffness are independent predictors of cardiovascular events. Arterial stiffness is not uniform across the arterial tree and its accurate assessment is challenging. The complex interactions and influence of aortic stiffness on carotid stiffness has not been investigated. The aim of this study was to evaluate the impact of aortic stiffness on carotid stiffness under physiological pressure conditions. A realistic patient-specific geometry was used based on MRI images obtained from the OsiriX library. The image was reconstructed using a three-dimensional slicer and the lumen boundary was reconstructed into the aorta and its branches. A series of simulations were performed at a different level of Young's modulus under two pulse pressure conditions to examine the deformation, compliance and von-Mises stress between the aorta and carotid arteries. An increase of Young's modulus resulted in a notable difference in the mechanical properties of the aortic tree. The deformation, compliance and Von Mises stress across all sections of the aorta and carotid arteries decreased with the increase of the aortic Young's modulus. Our results indicate that carotid stiffness may be associated with aortic stiffness. Large-scale clinical validation is warranted to examine the influence of aortic on carotid stiffness.
Fluctuation-induced free energy of thin peptide films

description: We apply the Lifshitz theory of dispersion forces to find a contribution to the free energy of peptide films which is caused by the zero-point and thermal fluctuations of the electromagnetic field. For this purpose, using available information about the imaginary parts of dielectric permittivity of peptides, the analytic representation for permittivity of typical peptide along the imaginary frequency axis is devised. Numerical computations of the fluctuation-induced free energy are performed at room temperature for the freestanding peptide films, containing different fractions of water, and for similar films deposited on dielectric (SiO$_2$) and metal (Au) substrates. It is shown that the free energy of a freestanding peptide film is negative and, thus, contributes to its stability. The magnitude of the free energy increases with increasing fraction of water and decreases with increasing thickness of a film. For peptide films deposited on a dielectric substrate the free energy is nonmonotonous. It is negative for thicker than 100 nm films, reaches the maximum value at some film thickness, but vanishes and changes its sign for thinner than 100 nm films. The fluctuation-induced free energy of peptide films deposited on metallic substrate is found to be positive which makes films less stable. In all three cases, simple analytic expressions for the free energy of sufficiently thick films are found. The obtained results may be useful to attain film stability in the next generation of organic microdevices with further shrinked dimensions.

description: According to Berry a wave-chaotic state may be viewed as a superposition of monochromatic plane waves with random phases and amplitudes. Here we consider the distribution of nodal points associated with this state. Using the property that both the real and imaginary parts of the wave function are random Gaussian fields we analyze the correlation function and densities of the nodal points. Using two approaches (the Poisson and Bernoulli) we derive the distribution of nearest neighbor separations. Furthermore the distribution functions for nodal points with specific chirality are found. Comparison is made with results from from numerical calculations for the Berry wave function.
