description: One of the biggest challenges the current STT-RAM industry faces is maintaining a high thermal stability while trying to switch within a given voltage pulse and energy cost. In this paper, we present a physics based analytical model that uses a modified Simmons' tunneling expression to capture the spin dependent tunneling in a magnetic tunnel junction(MTJ). Coupled with an analytical derivation of the critical switching current based on the Landau-Lifshitz-Gilbert equation, and the write error rate derived from a solution to the Fokker-Planck equation, this model provides us a quick estimate of the energydelay- reliability tradeoffs in perpendicular STTRAMs due to thermal fluctuations. In other words, the model provides a simple way to calculate the energy consumed during a write operation that ensures a certain error rate and delay time, while being numerically far less intensive than a full-fledged stochastic calculation. We calculate the worst case energy consumption during anti-parallel (AP) to parallel (P) and P to AP switchings and quantify how increasing the anisotropy field HK and lowering the saturation magnetization MS, can significantly reduce the energy consumption. A case study on how manufacturing variations of the MTJ cell can affect the energy consumption and delay is also reported.

description: We study the effects of disorder on the interlayer transport properties of disordered semiconductor bilayers outside of the quantum Hall regime by performing self-consistent quantum transport calculations. We find that the addition of material disorder to the system affects interlayer interactions leading to significant deviations in the interlayer transfer characteristics. In particular, we find that disorder decreases and broadens the tunneling peak, effectively reducing the interacting system to the non-interacting system, when the mean-free path for the electrons becomes shorter than the system length. Our results suggest that the experimental observation of exchange-enhanced interlayer transport in semiconductor bilayers requires materials with mean-free paths larger than the spatial extent of the system.

description: This white paper provides back ground and rationale for the priorities laid out in the Action Plan and summarizes our current understanding of mercury in the Gulf of Mexico ecosystem. In addition, the Action Plan emphasizes the identification of special at-risk consumers who ingest larger than average amounts of Gulf of Mexico fish, especially fish with higher than average mercury concentrations . For this reason, we have structured this white paper starting with mercury exposure to humans and proceeding along the mercury flow path backwards toward mercury sources and emissions to the environment. By so doing, the major GOMA goal of mitigating the risks of mercury exposure is emphasized. This flow path approach also helps to clarify where the flow of mercury might be disrupted to reduce the risk to consumers. We need to identify the fisheries where mercury poses the greatest risk to humans (and wildlife), determine the sources of the mercury, and understand where it is being methylated.

description: Motivated by the recent results in the standard model (SM) Higgs boson search at the Large Hadron Collider (LHC) we investigate the SM-like CP-even Higgs boson of the U(1)'-extended minimal supersymmetric standard model (UMSSM) and its branching ratio into the b b-bar, W W*, and χ^0_1 χ^0_1 modes. In the Summer 2011, a 2 sigma excess was reported in the channel H -> W W* -> l+ nu l- nu-bar around 130 - 140 GeV range. Later on in December 2011 announcements were made that an excess was seen in the 124-126 GeV range, while the SM Higgs boson above 131 GeV up to about 600 GeV is ruled out. We examine two scenarios of these mass ranges: (i) 130 GeV < M_{h_{SM-like}} < 141 GeV and show that the Higgs boson can decay into invisible neutralinos to evade the SM bound; and (ii) 120 GeV < M_{h_{\rm SM-like}} < 130 GeV and show that the Higgs boson can avoid decaying into neutralinos and thus gives enhanced rates into visible particles. We use the ηmodel of E_6 with TeV scale supersymmetry to illustrate the idea by scanning the parameter space to realize these two different scenarios.

description: The problem of estimating the parameters of a moving target in multiple-input multiple-output (MIMO) radar is considered and a new approach for estimating the moving target parameters by making use of the phase information associated with each transmit-receive path is introduced. It is required for this technique that different receive antennas have the same time reference, but no synchronization of initial phases of the receive antennas is needed and, therefore, the estimation process is non-coherent. We model the target motion within a certain processing interval as a polynomial of general order. The first three coefficients of such a polynomial correspond to the initial location, velocity, and acceleration of the target, respectively. A new maximum likelihood (ML) technique for estimating the target motion coefficients is developed. It is shown that the considered ML problem can be interpreted as the classic "overdetermined" nonlinear least-squares problem. The proposed ML estimator requires multi-dimensional search over the unknown polynomial coefficients. The Cramér-Rao Bound (CRB) for the proposed parameter estimation problem is derived. The performance of the proposed estimator is validated by simulation results and is shown to achieve the CRB.

description: Statistical methodology is proposed for comparing unlabeled marked point sets, with an application to aligning steroid molecules in chemoinformatics. Methods from statistical shape analysis are combined with techniques for predicting random fields in spatial statistics in order to define a suitable measure of similarity between two marked point sets. Bayesian modeling of the predicted field overlap between pairs of point sets is proposed, and posterior inference of the alignment is carried out using Markov chain Monte Carlo simulation. By representing the fields in reproducing kernel Hilbert spaces, the degree of overlap can be computed without expensive numerical integration. Superimposing entire fields rather than the configuration matrices of point coordinates thereby avoids the problem that there is usually no clear one-to-one correspondence between the points. In addition, mask parameters are introduced in the model, so that partial matching of the marked point sets can be carried out. We also propose an adaptation of the generalized Procrustes analysis algorithm for the simultaneous alignment of multiple point sets. The methodology is illustrated with a simulation study and then applied to a data set of 31 steroid molecules, where the relationship between shape and binding activity to the corticosteroid binding globulin receptor is explored.

description: Disorder increasingly affects performance as electronic devices are reduced in size. The ionized dopants used to populate a device with electrons are particularly problematic, leading to unpredictable changes in the behavior of devices such as quantum dots each time they are cooled for use. We show that a quantum dot can be used as a highly sensitive probe of changes in disorder potential, and that by removing the ionized dopants and populating the dot electrostatically, its electronic properties become reproducible with high fidelity after thermal cycling to room temperature. Our work demonstrates that the disorder potential has a significant, perhaps even dominant, influence on the electron dynamics, with important implications for `ballistic' transport in quantum dots.

description: Whether or not there is growing static order accompanying the dynamical heterogeneity and increasing relaxation times seen in glassy systems is a matter of dispute. An obstacle to resolving this issue is that the order is expected to be amorphous and so not amenable to simple order parameters. We use mutual information to provide a general measurement of order that is sensitive to multi-particle correlations. We apply this to two glass-forming systems (2D binary mixtures of hard disks with different size ratios to give varying amounts of hexatic order) and show that there is little growth of amorphous order in the system without crystalline order. In both cases we measure the dynamical length with a four-point correlation function and find that it increases significantly faster than the static lengths in the system as density is increased. We further show that we can recover the known scaling of the dynamic correlation length in a kinetically constrained model, the 2-TLG.

The magnetization measurements reveal fish-tail hysteresis loop and relatively high critical current density Jc ~ 0.8\times105 A/cm2 at low temperatures. The exponential temperature dependence of Jc, which arises from nonlinear effective flux-creep activation energy, has been observed. Upper critical field determined by resistive transition shows a relatively large anisotropy. The magneto-optical images reveal homogenous current flow within the crystal.

Effective interactions and operators in no-core shell model

Year: 2012
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Solutions to the nuclear many-body problem rely on effective interactions, and in general effective operators, to take into account effects not included in calculations. These include effects due to the truncation to finite model spaces where a numerical calculation is tractable, as well as physical terms not included in the description in the first place. In the no-core shell model (NCSM) framework, we discuss two approaches to the effective interactions based on (i) unitary transformations and (ii) effective field theory (EFT) principles. Starting from a given Hamiltonian, the unitary transformation approach is designed to take into account effects induced by the truncation to finite model spaces in which a numerical calculation is performed. This approach was widely applied to the description of nuclear properties of light nuclei; we review the theory and present representative results. In the EFT approach, a Hamiltonian is always constructed in a truncated model space according to the symmetries of the underlying theory, making use of power counting to limit the number of interactions included in the calculations. Hence, physical terms not explicitly included in the calculation are treated on the same footing with the truncation to a finite model space. In this approach, we review results for both nuclear and trapped atomic systems, for which the effective theories are formally similar, albeit describing different underlying physics. Finally, the application of the EFT method of constructing effective interactions to Gamow shell model is briefly discussed.

description: A scheme for rapidly and accurately computing solutions to boundary integral equations (BIEs) on rotationally symmetric surfaces in R^3 is presented. The scheme uses the Fourier transform to reduce the original BIE defined on a surface to a sequence of BIEs defined on a generating curve for the surface. It can handle loads that are not necessarily rotationally symmetric. Nystrom discretization is used to discretize the BIEs on the generating curve. The quadrature is a high-order Gaussian rule that is modified near the diagonal to retain high-order accuracy for singular kernels. The reduction in dimensionality, along with the use of high-order accurate quadratures, leads to small linear systems that can be inverted directly via, e.g., Gaussian elimination. This makes the scheme particularly fast in environments involving multiple right hand sides. It is demonstrated that for BIEs associated with the Laplace and Helmholtz equations, the kernel in the reduced equations can be evaluated very rapidly by exploiting recursion relations for Legendre functions. Numerical examples illustrate the performance of the scheme; in particular, it is demonstrated that for a BIE associated with Laplace's equation on a surface discretized using 320,800 points, the set-up phase of the algorithm takes 1 minute on a standard laptop, and then solves can be executed in 0.5 seconds.

ABSTRACT

Seed fatty acids (FAs) and triacylglycerol (TAG) contribute to many functions in plants, and seed lipids have broad food, feed and industrial applications. As a result, an enormous amount of attention has been dedicated towards uncovering the regulatory cascade responsible for the fine44 tuning of the lipid biosynthetic pathway in seeds, which is regulated in part through the action of LEAFY COTYLEDON1, ABSCISSIC ACID INSENSITIVE 3, FUSCA3 and LEC2 (LAFL) transcription factors. Although AINTEGUMENTA-LIKE 7 (AIL7) is involved in meristematic function and shoot phyllotaxy, its effect in the context of lipid biosynthesis has yet to be assessed. Here we generated AIL7 seed-specific over-expression lines and found that they exhibited significant alterations in FA composition and decreased total lipid accumulation in seeds. Seeds and seedlings from transgenic lines also exhibited morphological deviations compared to wild-type. Correspondingly, RNA-Seq analysis demonstrated that the expression of many genes related to FA biosynthesis and TAG breakdown were significantly altered in developing siliques from transgenic lines compared to wild-type plants. The seed-specific over expression of AIL7 also altered the expression profiles of many genes related to starch metabolism, photosynthesis and stress response, suggesting further roles for AIL7 in plants. These findings not only advance our understanding of the lipid biosynthetic pathway in seeds, but also provide evidence for additional functions of AIL7, which could prove valuable in downstream breeding and/or metabolic engineering endeavours.

description: We present analysis of the UV-spectrum of the low-z AGN IRAS-F22456-5125 obtained with the Cosmic Origins Spectrograph on board the Hubble Space Telescope. The spectrum reveals six main kinematic components, spanning a range of velocities of up to 800 km s-1, which for the first time are observed in troughs associated with CII, CIV, NV, SiII, SiIII, SiIV and SIV. We also obtain data on the OVI troughs, which we compare to those available from an earlier FUSE epoch. Column densities measured from these ions allow us to derive a well-constrained photoionization solution for each outflow component. Two of these kinematic components show troughs associated with transitions from excited states of SiII\ and CII. The number density inferred from these troughs, in combination with the deduced ioinization parameter, allows us to determine the distance to these outflow components from the central source. We find these components to be at a distance of ~ 10 kpc. The distances and the number densities derived are consistent with the outflow being part of a galactic wind.

Temporal Analysis of Land Surface Temperature and Urban Heat Island Dynamics: A Comparative Study of Kochi and Fairbanks (2000-2023)
Creators: name: Dr. Bindu G
Publisher: name: Zenodo
Year: 2024

description: This project investigates the Land Surface Temperature (LST) trends and Urban Heat Island (UHI) effects in Kochi, India, and Fairbanks, Alaska, from 2000 to 2023, offering a comparative analysis of two geographically and climatically distinct regions. The study reveals significant warming trends in Kochi, with an increase of 1.6°C in summer and 1.9°C in winter, highlighting the impact of urbanization and regional climate dynamics. In contrast, Fairbanks shows a moderate increase of 1.04°C in summer, but a slight decrease of 0.063°C in winter, reflecting the influence of local climatic factors such as increased snowfall.

The research identifies a significant warming anomaly during the years 2014-2016, attributed to El Niño events, with 2014 experiencing a minor El Niño and 2016 marked by a major one. These global climatic phenomena intensified the warming trends in Kochi, particularly during this period. The study also highlights the role of regional climatic events, such as the early onset of the pre-monsoon season in Kochi, which contributed to cooling effects during certain months, thereby moderating the overall warming trend.

The UHI effect is evident in both cities, with Kochi experiencing notable fluctuations between seasons. In Kochi, the summer UHI decreased from 1.7°C in 2014 to 0.8°C in 2023, while the winter UHI increased from 0.5°C to 1.4°C over the same period. In Fairbanks, the UHI effect showed a slight increase in summer but a decrease in winter, illustrating the varying influence of urbanization and regional climatic conditions.

The study concludes that extreme climatic conditions are becoming more pronounced, as evidenced by the intensification of winter UHI in Fairbanks. This research underscores the need for targeted strategies to mitigate the impacts of warming trends and UHI effects in urban areas, particularly in the face of increasing climate variability and extreme weather events

description: Recently, the vacuum energy of the QCD ghost in a time-dependent background is proposed as a kind of dark energy candidate to explain the acceleration of the universe. In this model, the energy density of the dark energy is proportional to the Hubble parameter $H$, which is the Hawking temperature on the Hubble horizon of the Friedmann-Robertson-Walker (FRW) universe. In this paper, we perform a constraint on the ghost dark energy model with and without bulk viscosity, by using the Markov Chain Monte Carlo (MCMC) method and the combined latest observational data from the type Ia supernova compilations including Union2.1(580) and Union2(557), cosmic microwave background, baryon acoustic oscillation, and the observational Hubble parameter data.

Cosmic muons and gamma rays traverse two synchronized scintillators connected to two photomultiplier tubes (PMT) via light guides, and generate electronic pulses which we counted using a Data Acquisition Board (DAQ). Because muons are the product of collisions between high-energy cosmic rays and atmospheric nuclei, and therefore shower onto earth, the scintillators were arranged horizontally for detection. The elevation measurements were recorded at different locations, starting from 60 feet below sea-level at the Underground Radiation Counting Laboratory at Johnson Space Center, TX, to 4200 feet at Mt. Hamilton, CA. Intermediate locations included sea-level Galveston Bay, TX, and Mt. Magazine, AR (2800 feet). The data points showed a noticeable increase in flux as elevation increases, independent of latitude. Measurements investigating the dependence of cosmic rays on temperature and time of the year took place locally in Magnolia, AR. We found that cosmic muon flux is uniform, appears to be independent of conditions on earth, and is anti-correlative with temperature. We are convinced that the sun has minimal to zero effect on cosmic-ray flux; it cannot be a major contributing source of this background radiation. The source of cosmic radiation remains one of the biggest unanswered questions in physics today.

description: We present the VOEventNet infrastructure for large-scale rapid follow-up of astronomical events, including selection, annotation, machine intelligence, and coordination of observations. The VOEvent standard is central to this vision, with distributed and replicated services rather than centralized facilities. We also describe some of the event brokers, services, and software that are connected to the network. These technologies will become more important in the coming years, with new event streams from Gaia, LOFAR, LIGO, LSST, and many others.

description: Different building blocks in organic molecules could induce complex intermolecular interactions to lead to different supramolecular micro/nanostructures in bulk and solution states. Herein, the first new phenolphthalein-based hexacatenar containing a central phenolphthalein fluorochrome functionalized with two dendritic wings is synthesized by click reaction. The polarized optical microscopy, differential scanning calorimetry, and small-angle X-ray diffraction data demonstrated that the reported phenolphthalein-based hexacatenar could self-assemble into hexagonal columnar mesophase in the bulk state and could form organogel with distinct morphologies in some common organic solvents due to intermolecular interactions. Density functional theory calculation results showed highly twisted molecular conformation, distinct charge distribution, and asymmetrical electronic property, which might be essential for the stabilization of columnar mesophase and organogel. Therefore, this work provides a method to develop soft materials containing different functional building blocks with complex self-assemblies.

description: The statistical mechanics of DNA denaturation under fixed linking number is qualitatively different from that of the unconstrained DNA. Quantitatively different melting scenarios are reached from two alternative assumptions, namely, that the denatured loops are formed in expense of 1) overtwist, 2) supercoils. Recent work has shown that the supercoiling mechanism results in a BEC-like picture where a macroscopic loop appears at Tc and grows steadily with temperature, while the nature of the denatured phase for the overtwisting case has not been studied. By extending an earlier result, we show here that a macroscopic loop appears in the overtwisting scenario as well. We calculate its size as a function of temperature and show that the fraction of the total sum of microscopic loops decreases above Tc, with a cusp at the critical point.

description: Publicly available clock correction data from the Global Positioning System was analyzed and used in combination with the results of terrestrial clock comparison experiments to confirm the local position invariance (LPI) of Planck's constant within the context of general relativity. The results indicate that h is invariant within a limit of |beta_h|<0.007, where beta_h is a dimensionless parameter that represents the extent of LPI violation.

description: This work produced a polyelectrolyte, sulfonated polystyrene (PSS) from polystyrene waste. The resulting PSS was characterized by FTIR spectrometry, which shows the bands of the sulfur trioxide group. Thermogravimetric analysis (TGA) confirms the material’s high stability compared to the starting material. The interactions between oppositely charged polyelectrolyte (PSS) and the surfactant cocamidopropyl betaine (CAPB) in an aqueous solution of three different pH values were also studied at 25°C, using conductimetry and viscometry techniques. The CMC of the surfactant is above the critical aggregation concentration (CAC) and well below the C2 (saturation concentration). PSS interacts strongly with the zwitterionic surfactant CAPB. At pH 2.5, the polymer is a strong polyanion, and binding is dominated by electrostatic charge neutralization with the cationic surfactant at this pH. At pH 5.2 and 9, the electrostatic attraction between CAPB and PSS weakens, and the hydrophobic interaction strengthens. The effect of salt concentration on the interaction between CAPB and PSS depends on the competition between increasing interaction and filtering interaction. The ionic strength is essential to these interactions after salt and acid injection. CAC and C2 are affected by the charge of the electrolyte and the medium due to the synergistic effects of alkali on the surfactant compared to the polymer system without alkali-surfactant and probably also due to the increase in the formed bond between the polyelectrolyte and the surfactant in the presence of salt.

description: In this paper, we investigate the dynamics of clumps embedded in and confined by the advection-dominated accretion flows (ADAF), in which collisions among the clumps are neglected. We start from the collisionless Boltzmann equation and assume that interaction between the clumps and the ADAF is responsible for transporting angular momentum of clumps outward. The inner edge of the clumpy-ADAF is set to be the tidal radius of the clumps. We consider strong and weak coupling cases, in which the averaged properties of clumps follow the ADAF dynamics and mainly determined by the black hole potential, respectively. We get the analytical solution of the dynamics of clumps for the two cases. The velocity dispersion of clumps is one magnitude higher than the ADAF for the strong coupling case. For the weak coupling case, we find that the mean radial velocity of clumps is linearly proportional to the coefficient of the drag force. We show that the tidally disrupted clumps would lead to accumulation of the debris to form a debris disk in the Shakura-Sunyaev regime. The entire hot ADAF will be efficiently cooled down by photons from the debris disk, giving rise to collapse of the ADAF and quench the clumpy accretion. Subsequently, evaporation of the collapsed ADAF drives resuscitate of a new clumpy-ADAF, resulting in an oscillation of the global clumpy-ADAF. Applications of the present model are briefly discussed to X-ray binaries, ionization nuclear emission regions (LINERs) and BL Lac objects.

description: Efficient treatment of stress-related disorders, such as depression, is still a major challenge. The onset of antidepressant drug action is generally quite slow, while the anxiolytic action of benzodiazepines is considerably faster. However, their long-term use is impaired by tolerance development, abuse liability and cognitive impairment. Benzodiazepines act as positive allosteric modulators of ɣ-aminobutyric acid type A (GABAA) receptors. 3α-reduced neurosteroids such as allopregnanolone also are positive allosteric GABAA receptor modulators, however, through a site different from that targeted by benzodiazepines. Recently, the administration of neurosteroids such as brexanolone or zuranolone has been shown to rapidly ameliorate symptoms in post-partum depression or major depressive disorder. An attractive alternative to the administration of exogenous neurosteroids is promoting endogenous neurosteroidogenesis via the translocator protein 18k Da (TSPO). TSPO is a transmembrane protein located primarily in mitochondria, which mediates numerous biological functions, e.g., steroidogenesis and mitochondrial bioenergetics. TSPO ligands have been used in positron emission tomography (PET) studies as putative markers of microglia activation and neuroinflammation in stress-related disorders. Moreover, TSPO ligands have been shown to modulate neuroplasticity and to elicit antidepressant and anxiolytic therapeutic effects in animals and humans. As such, TSPO may open new avenues for understanding the pathophysiology of stress-related disorders and for the development of novel treatment options.

description: Particle size distribution (PSD) is one of the critical attributes of crystals. PSD not only influences downstream processes but also controls final product performance in crystallization. In this work, we have used the model system of methanol–water-paracetamol for carrying out anti-solvent crystallization to produce paracetamol crystals. With reference to a base case of anti-solvent crystallization in a stirred tank, we have used three devices connected to the stirred tank with an external loop with full recycling. A peristaltic pump was used to circulate the contents of the stirred tank in an external loop comprising a simple tube, a fluidic oscillator (FO), and a vortex diode (VD). Anti-solvent was introduced at a point lying between the pump and these three devices to understand the influence of these devices on mixing and potential particle breakage. The PSD of crystals obtained with these three devices are compared with that of the base case for one supersaturation ratio (SSR = 1.63). The results indicated the potential of manipulating the PSD of crystals with a strategy of using fluidic devices in an external loop. The overall arrangement can be potentially extended to continuous crystallization.

description: This paper studies a downlink multiuser transmit beamforming design under spherical channel uncertainties, using a worst-case robust formulation. This robust design problem is nonconvex. Recently, a convex approximation formulation based on semidefinite relaxation (SDR) has been proposed to handle the problem. Curiously, simulation results have consistently indicated that SDR can attain the global optimum of the robust design problem. This paper intends to provide some theoretical insights into this important empirical finding. Our main result is a dual representation of the SDR formulation, which reveals an interesting linkage to a different robust design problem, and the possibility of SDR optimality.

description: We study the dynamical description of scalar-tensor gravity by performing the best-fit analysis for two cases of exponential and power-law form of the potential and scalar field function coupled to the curvature. The models are then tested against observational data. The results show that in both scenarios the Universe undergoes an acceleration expansion period and the geometrical equivalent of dark energy is associated with a time-dependent equation of state.
