description: Cross-modal embeddings, between textual and visual modalities, aim to organise multimodal instances by their semantic correlations. State-of-the-art approaches use maximum-margin methods, based on the hinge-loss, to enforce a constant margin m, to separate projections of multimodal instances from different categories. In this paper, we propose a novel scheduled adaptive maximum-margin (SAM) formulation that infers triplet-specific constraints during training, therefore organising instances by adaptively enforcing inter-category and inter-modality correlations. This is supported by a scheduled adaptive margin function, that is smoothly activated, replacing a static margin by an adaptively inferred one reflecting triplet-specific semantic correlations while accounting for the incremental learning behaviour of neural networks to enforce category cluster formation and enforcement. Experiments on widely used datasets show that our model improved upon state-of-the-art approaches, by achieving a relative improvement of up to ~12.5% over the second best method, thus confirming the effectiveness of our scheduled adaptive margin formulation.

description: To build a sustainable and affordable space transportation system for human space exploration, the design and deployment of space infrastructures are critical; one attractive and promising infrastructure system is the in-situ resource utilization (ISRU) system. The design analysis and trade studies for ISRU systems require the consideration of not only the design of the ISRU plant itself but also other infrastructure systems (e.g., storage, power) and various ISRU architecture options (e.g., resource, location, technology). This paper proposes a system-level space infrastructure and its logistics design optimization framework to perform architecture trade studies. A new space infrastructure logistics optimization problem formulation is proposed that considers infrastructure subsystems' internal interactions and their external synergistic effects with space logistics simultaneously. Since the full-size version of this proposed problem formulation can be computationally prohibitive, a new multi-fidelity optimization formulation is developed by varying the granularity of the commodity type definition over the network graph; this multi-fidelity formulation can find an approximation solution to the full-size problem computationally efficiently with little sacrifice in the solution quality. The proposed problem formulation and method are applied to a multi-mission lunar exploration campaign to demonstrate their values.

description: This paper presents an empirical investigation into the operational benefits of passing lanes on rural two-lane highways. Two study sites in the state of Montana were used in this investigation. Performance was examined at a single location upstream and multiple locations downstream of the passing lane at each study site. Using percent followers as a performance measure, operational benefits right after the passing lane ranged between 33% and 42% at one study site and 12% to 19% at the other study site under prevalent traffic levels. Study results also suggest that operational benefits persist for a remarkable distance beyond the end of the passing lane.

description: In this work we consider the oscillations and associated resonance of a 2D Bose-Einstein condensate under periodic and random modulations of the atomic scattering length. For random oscillations of the trap potential and of the atomic scattering length we are able to calculate the mean growth rate for the width of the condensate. The results obtained from the reduced ODE's for oscillations of the width of condensate are compared with the numerical simulations of the full 2D Gross-Pitaevskii equation with modulated in time coefficients.

A Hypothetical Source of Dark Matter: Fragmentation and Clustering of Black Hole Remnants Following a Universal Eruption
Creators: name: Rao, Lawrence
Publisher: name: Zenodo
Year: 2024
Subjects: cosmology

description: This hypothesis proposes that a Universal Eruption of a supermassive black hole (Rao, 2024) could lead to the fragmentation of its material into smaller black holes, ranging from stellar to intermediate masses. These fragmented black holes, dispersed throughout the universe, might gravitationally interact with emerging cosmic structures. Rather than accreting all nearby baryonic matter, these black holes could cluster and act as gravitational seeds, influencing galaxy formation. We suggest that these primordial black holes (PBHs), remnants of the eruption, could constitute a significant portion of dark matter. Since PBHs do not emit detectable electromagnetic radiation, their gravitational effects could account for the missing mass inferred from cosmic observations, potentially offering an alternative explanation for dark matter.

description: A human factors study consisting of a vehicle headway analysis and a questionnaire survey was conducted in Rhode Island (RI) to investigate tailgating issues and possible means for tailgating treatment. Vehicle headways were collected from highway surveillance videos and serious tailgating issues were identified on RI highways. The results of the questionnaire survey further confirmed the observations made in the vehicle headway analysis that most RI drivers maintained insufficient vehicle headways on highways. Among a few tailgating treatments presented in the survey, most subjects preferred a system consisting of equally spaced, white horizontal bars marked on pavement and overhead graphic-aided dynamic message signs.

description: This paper examines the effects of increased car weights, train size, and distance on railroad operational performance, which is measured in revenue ton-miles per train hour. A statistical model is estimated from Class I data that explains most of the variation in this index, while controlling for commodity and fixed network effects. The results suggest that length of haul, net load, and train size contributed significantly to performance gains from 1987 to 2006. However, train miles per track mile increased by 89% during the same period, resulting in line and yard congestion.

description: In this talk we present the results of the investigation on the so called double parton distribution functions (dPDFs), accessible quantities in high energy proton-proton and proton nucleus collisions, in double parton scattering processes (DPS). These new and almost unknown distributions encode information on how partons inside a proton are correlated among each other and represent a new tool to explore the three dimensional partonic structure of hadrons. In the present contribution, results of the calculations of dPFDs are presented also including phenomenological investigations on the impact of double correlations in experimental observables, showing how the latter could be observed in the next LHC run. In addition we discuss how present information on experimental observables could be related to the transverse proton structure.

description: In this paper, we extend our analysis of lattice systems using the wavelet transform to systems for which exact enumeration is impractical. For such systems, we illustrate a wavelet-accelerated Monte Carlo (WAMC) algorithm, which hierarchically coarse-grains a lattice model by computing the probability distribution for successively larger block spins. We demonstrate that although the method perturbs the system by changing its Hamiltonian and by allowing block spins to take on values not permitted for individual spins, the results obtained agree with the analytical results in the preceding paper, and ``converge'' to exact results obtained in the absence of coarse-graining. Additionally, we show that the decorrelation time for the WAMC is no worse than that of Metropolis Monte Carlo (MMC), and that scaling laws can be constructed from data performed in several short simulations to estimate the results that would be obtained from the original simulation. Although the algorithm is not asymptotically faster than traditional MMC, because of its hierarchical design, the new algorithm executes several orders of magnitude faster than a full simulation of the original problem. Consequently, the new method allows for rapid analysis of a phase diagram, allowing computational time to be focused on regions near phase transitions.

description: A review of recent applications of the nonlocal dispersive optical model (DOM) is presented that allows a simultaneous description of nuclear structure and nuclear reactions. An assessment of the quality of the resulting potentials for $^{40}$Ca and $^{48}$Ca is discussed for the description of the $(e,e'p)$ reaction to valence hole states and the possibility of interpreting the data in terms of absolute spectroscopic factors. The relevance of these results in the context of conflicting interpretations between transfer and knockout reactions is pointed out as well as the importance of proton reaction cross sections for isotopes with neutron excess. Application of the nonlocal DOM to $^{48}$Ca incorporates the effect of the 8 additional neutrons and allows for an excellent description of elastic scattering data of both protons and neutrons. The corresponding neutron distribution constrained by all available data generates a prediction for the neutron skin that is larger than most mean-field and available \textit{ab initio} results. Results are presented for the most recent nonlocal DOM analysis of $^{208}$Pb.

description: The wild species of Solanum are important genetic resources for the medicinal and vegetable crop species of the genus and reservoir of genes for developing new economic uses of Solanum species. In this article, the genetic diversity and systematics of 14 Solanum accessions representing 11 species growing in the southwestern highlands of Saudi Arabia were evaluated using morphological variations and molecular polymorphism generated by 13 ISSR primers. Substantial variations were scored in 26 morphological characters and reflected in the cluster analysis of the examined accessions based on morphological variation. In the cluster trees illustrating the relatedness of the examined accessions based on morphological variation and ISSR polymorphism, the accessions of S. villosum and S. nigrum were differentiated as one cluster and S. dulcamara was associated with S. sisymbriifolium. In the meantime, S. coagulans was clustered with S. macracanthum. The analysis of ISSR data confirms that S. villosum is related to S. nigrum and supports the grouping S. incanum and S. glabratum based on the morphological traits. Principle Component Analysis (PCA) analysis of morphological and ISSR data as a combined set, differentiated the examined species into four groups in a scatter plot. The differentiation of the species/populations in the PCA scatter diagram agrees with their separation in the cluster trees. The four groups are 1. S. macracanthum, S. coagulans and S. schimperianum. 2. S. glabratum and S. incanum. 3. S. dulcamara, S. sisymbriifolium and S. torvum, 4. S. nigrum, S. villosum, and S. villosum ssp. puniceum.

description: Leasing has always been an important source of finance to carriers in the U.S. airline industry. In the 1960-1970s, many carriers employed a type of lease called a financial lease as an alternative source of funds to acquire aircraft. It had a major advantage over purchasing the aircraft. It was “off-the-balance sheet financing,” as the obligations under this type of lease appeared only in the footnotes to carrier balance sheets. Little use was made of short-term lease agreements during this period. The situation has changed radically over the past three decades. In 1976, the Financial Accounting Standards Board issued SFAS No. 13 defining specific criteria for capital leases that required the reporting of these “off-the-balance sheet financing” as both a leasehold asset and a long-term liability recorded under the long-term debt section of the balance sheet. In response, the air carriers substantially altered the way they finance airplanes. Carriers began to lease more and more of their aircraft, but they did so by structuring leases as shorter-term operating leases, which are not reported on companies’ balance sheets. By strategically violating the criteria for capital leases, the air carriers once again pushed the leases off the balance sheet. The purpose of this research is to demonstrate the switch in the characteristics of aircraft leasing and to quantify the effects of such leases on air carrier debt burdens. In the process it will be argued that “debt is debt” no matter how it is structured. The paper updates two research studies by the authors to 2008.

description: Agricultural and other shippers are concerned about the sufficiency in rural areas of transportation capacity, the sufficiency of competition in the transportation system, the reliability of transportation services, and the reasonableness of rates. This paper examines the sufficiency of rail freight competition and the effects of intramodal competition on rail rates. The paper begins with a review of the importance of rail transportation for U.S. agricultural producers. Specific attention is paid to the nature of competition faced by railroads, especially since deregulation, using the analytical tool of inverse Herfindahl-Hirschman Indices (HHI), by USDA Crop Reporting Districts (CRD). As shown by the inverse HHIs, the overall level of rail competition for grains and oilseeds has generally decreased since the 1985-1992 period, even though rail competition has increased for some CRDs. In addition, revenue to variable cost ratios (R/VC) increased in most of the CRDs analyzed, and the analysis found them related to the number of railroads competing in the CRD. Competition is then analyzed relative to the revenue per ton, revenue per ton-mile, and the revenue to variable cost ratios (R/VC) associated with the level of competition for six states with the least rail-to-rail competition, and distant from water transportation, with those for four states having more rail-to-rail competition and close proximity to water transportation.

description: We find that photoexcited electrons in an n-GaAs epilayer rapidly (< 50 ps) spin-polarize due to the proximity of an epitaxial ferromagnetic metal. Comparison between MnAs/GaAs and Fe/GaAs structures reveals that this coherent spin polarization is aligned antiparallel and parallel to their magnetizations, respectively. In addition, the GaAs nuclear spins are dynamically polarized with a sign determined by the spontaneous electron spin orientation. In Fe/GaAs, competition between nuclear hyperfine and applied magnetic fields results in complete quenching of electron spin precession.

description: Paclitaxel-loaded poly(lactic acid-co-glycolic acid) (PLGA) microspheres containing different portions of human serum albumin microparticles (mHSA) were prepared via an in situ forming method. The low solubility of Paclitaxel and presence of an external oil phase around the in situ-formed microspheres were investigated with the mathematical models based on the diffusion-control release. The release data were fitted with diffusion-based semi-empirical models including Ritger-Peppas, Weibull and Peppas-Sahlin models, and a theoretical model obtained from Fick’s second law. The release rate constants, release exponent and average drug diffusion coefficients microspheres were calculated and their variations with PLGA molecular weight and microparticles were established. Results showed good accordance between experimental and theoretical values. Besides, incorporation of mHSA within microspheres decreased the Paclitaxel diffusion. Result of docking studies showed that the binding site of mHSA sequences including HIS242 and ARG114 have more significant interaction with paclitaxel, but no significant interaction between PLGA and paclitaxel.

description: This paper examines differences between Northwest Europe and Eastern North America with respect to port commercial activities, port policy, port hinterland access and competition, port governance, and port security. While the volume of traffic on the transatlantic trade route has grown, its share of world trade with Europe has declined slightly. The authors explore the relevant contextual issues the ports on the trade route have experienced in the last decade, and using the Baltazar and Brooks (2001) Environment-Strategy-Structure framework, examine the structure and strategies followed by ports as they seek to deal with the changing environment (context) on all routes, not just the transatlantic.

description: In this study we consider the shortest path problem, where the arc costs are subject to distributional uncertainty. Basically, the decision-maker attempts to minimize her worst-case expected loss over an ambiguity set (or a family) of candidate distributions that are consistent with the decision-maker's initial information. The ambiguity set is formed by all distributions that satisfy prescribed linear first-order moment constraints with respect to subsets of arcs and individual probability constraints with respect to particular arcs. Under some additional assumptions the resulting distributionally robust shortest path problem (DRSPP) admits equivalent robust and mixed-integer programming (MIP) reformulations. The robust reformulation is shown to be $NP$-hard, whereas the problem without the first-order moment constraints is proved to be polynomially solvable. We perform numerical experiments to illustrate the advantages of the considered approach; we also demonstrate that the MIP reformulation of DRSPP can be solved effectively using off-the-shelf solvers.

description: We describe and illustrate Catasetum kamatawara from the Loreto Department of the Amazonian wetlands in Peru. An extensive comparison with several related species is presented including Catasetum cotylicheilum which is morphologically close to our species but differs mainly in having a three-lobed labellum with a three-dentate apex formed by its obtuse apices of lateral lobes and mid-lobe (vs. unlobed labellum with obtuse-rounded apex), and the presence of 4–5 transversely verrucose keels (vs. elevated, smooth callus). Additionally, we also report C. boyi, C. longifolium and C. semicirculatum which have not been previously reported for the Peruvian orchid flora. Finally, we propose a lectotype for the rare C. peruvianum based on the original illustration of the species.
Bistable Gradient Networks II: Storage Capacity and Behaviour Near Saturation

description: We examine numerically the storage capacity and the behaviour near saturation of an attractor neural network consisting of bistable elements with an adjustable coupling strength, the Bistable Gradient Network (BGN). For strong coupling, we find evidence of a first-order "memory blackout" phase transition as in the Hopfield network. For weak coupling, on the other hand, there is no evidence of such a transition and memorized patterns can be stable even at high levels of loading. The enhanced storage capacity comes, however, at the cost of imperfect retrieval of the patterns from corrupted versions.

description: We briefly review the Thomas-Fermi statistical model of atoms in the classical non-relativistic formulation and in the generalised finite-nucleus relativistic formulation. We then discuss the classical generalisation of the model to finite temperatures in the non-relativistic approximation and present a new relativistic model at finite temperatures, investigating how to recover the existing theory in the limit of low temperatures. This work is intended to be a propedeutical study for the evaluation of equilibrium configurations of relativistic ``hot'' white dwarfs.

description: In defence against environmental constraints, plants respond by changing their morphology and/or physiology and this reaction can be a manifestation of a life strategy. Amphibious plants are good models to test for life strategies because they display plastic responses to aquatic and terrestrial conditions. In our study we investigated the architecture and phenotypic responses of the boreal plant Ranunculus reptans L. to water level changes by observing spontaneous aquatic populations during their flowering period and by conducting experimental transplantation. We interpret these data (1) in terms of adaptation to aquatic versus terrestrial conditions, and (2) as a manifestation of the life strategy. We document a radical change in R. reptans architecture and reproduction. Reduction of plant size, elongation of leaves and stolons, vegetative reproduction are characteristic of aquatic plants. Terrestrial plants are bigger, with wider lanceolate leaves and shorter stolons leading to higher density; they reproduce vegetatively and generatively. R. reptans appeared to follow the avoidance life strategy: (1) small growth form in aquatic conditions minimises the frontal area and diminishes the risk of uprooting; (2) elongated submerged leaves decrease hydraulic resistance and mechanical damages; (3) formation of individuals with multiple axes reduce the risk of uprooting by waves; (4) capacity to quickly reconfigure the architectural traits of aquatic and terrestrial plants adjusts them to changes in environmental conditions. Our findings thus suggest that R. reptans is phenotypically plastic and adjusts vegetatively to water level, essentially reflecting an avoidance strategy, while using complementarily terrestrial and aquatic conditions in its reproduction.
Self-similar spherical shock solution with sustained energy injection

description: We present the generalization of the Sedov-Taylor self-similar strong spherical shock solution for the case of a central energy source varying in time, $E=A t^k$, where $A$ and $k$ are constants. The known Sedov-Taylor solution corresponds to a particular adiabatic case of $k=0$ or \emph{instant shock} with an instant energy source of the shock, $E=A$. The self-similar hydrodynamic flow in the nonadiabatic $k\neq0$ case exists only under the appropriate local entropy (energy) input which must be supported by some radiative mechanism from the central engine. The specific case of $k=1$ corresponds to a permanent energy injection into the shock, or injection shock with a central source of constant luminosity, $L=A$, $E=A t$. The generalized self-similar shock solution may be applied to astrophysical objects in which the duration of central source activity is longer than the shock expansion time, e.g. the early phase of SN explosions, strong wind from stars and young pulsars, non-steady spherical outflow from black holes and collapsing dense stellar clusters with numerous neutron star collisions.

description: Carbons are increasingly important as possible alternatives to expensive metal catalysts owing to the wide range of chemical properties they can exhibit and the growing
set of synthetic methods available to produce them. This thesis explores the use of polyacrylonitrile-containing precursors in the controlled synthesis of nanostructured,
heteroatom enriched carbons. Using these well-defined carbons, features that affect catalytic activity were determined for a variety of catalytic applications. Computational studies were also used to probe for catalytic active sites, and the electronic and spin properties of carbon systems were explored. The results presented provide insight into how nanostructure and microstructure affect catalytic activity and possible ways in which the
electronic properties that lead to catalytic activity might emerge.

description: This paper analyses rice traders’ behaviour pattern in general, and their stocking decisions in particular, based on information collected through a field survey in and around Dhaka city. It was observed that traders’ (both wholesalers and retailers ) stocking decisions were influenced by prices expected in the future, but the time frame of such expectation was confined to one week. Among the set of factors specifically related to operation of Public Food Distribution System, it was observed that most of the traders both in the wholesaler sad retailer groups, considered open market sale (OMS) of foodgrains by the Government as an important factor influencing their stocking decisions. This, therefore, underscores the need to devise appropriate measues in arresting price hike during the lean season, for greater involvement of private grain dealers in the public foodgrain distribution system.

description: Large-scale and multidimensional spatiotemporal data sets are becoming ubiquitous in many real-world applications such as monitoring urban traffic and air quality. Making predictions on these time series has become a critical challenge due to not only the large-scale and high-dimensional nature but also the considerable amount of missing data. In this paper, we propose a Bayesian temporal factorization (BTF) framework for modeling multidimensional time series -- in particular spatiotemporal data -- in the presence of missing values. By integrating low-rank matrix/tensor factorization and vector autoregressive (VAR) process into a single probabilistic graphical model, this framework can characterize both global and local consistencies in large-scale time series data. The graphical model allows us to effectively perform probabilistic predictions and produce uncertainty estimates without imputing those missing values. We develop efficient Gibbs sampling algorithms for model inference and model updating for real-time prediction and test the proposed BTF framework on several real-world spatiotemporal data sets for both missing data imputation and multi-step rolling prediction tasks. The numerical experiments demonstrate the superiority of the proposed BTF approaches over existing state-of-the-art methods.

description: For the classical principal chiral model with boundary, we give the subset of the Yangian charges which remains conserved under certain integrable boundary conditions, and extract them from the monodromy matrix. Quantized versions of these charges are used to deduce the structure of rational solutions of the reflection equation, analogous to the 'tensor product graph' for solutions of the Yang-Baxter equation. We give a variety of such solutions, including some for reflection from non-trivial boundary states, for the SU(N) case, and confirm these by constructing them by fusion from the basic solutions.

description: The credit aspects of the Intensive Transplanted Aman Programme (ITAP) has been investigated in this study. Distribution of ITAP loan was size neutral. Per acre credit need estimated by ITAP was inadequate compared to actuai per acre cost of production. ITAP loan utilization and repayment were found to be unsatisfactory. Loan distribution mechanism has not been free from vested influence. ITAP loan has been appropriated by a good proportion of farmers who did not raise any aman. Substantial non-interest costs were required in getting ITAP loan.
