Localization in splitting of matter waves

In this paper we present an analysis of how matter waves, guided as propagating modes in potential structures, are split under adiabatic conditions. The description is formulated in terms of localized states obtained through a unitary transformation acting on the mode functions. The mathematical framework results in coupled propagation equations that are decoupled in the asymptotic regions as well before as after the split. The resulting states have the advantage of describing propagation in situations, for instance matter-wave interferometers, where local perturbations make the transverse modes of the guiding potential unsuitable as a basis. The different regimes of validity of adiabatic propagation schemes based on localized versus delocalized basis states are also outlined. Nontrivial dynamics for superposition states propagating through split potential structures is investigated through numerical simulations. For superposition states the influence of longitudinal wave-packet extension on the localization is investigated and shown to be accurately described in quantitative terms using the adiabatic formulations presented here.
Temporal change of interplate coupling in northeastern Japan during 1995–2002 estimated from continuous GPS observations

SUMMARY Temporal change of deformation in northeastern Japan is clarified by continuous Global Positioning System (GPS) observations from 1995 April to 2002 March. The observed GPS velocity is approximately parallel to the direction of plate convergence on east and west plate boundaries of northeastern Japan and shows post-seismic transient deformation around source regions of the Mw 7.8 1993 Hokkaido-Nansei-Oki and the Mw 7.7 1994 Sanriku-Haruka-Oki earthquakes. We interpret the source of the observed deformation as contemporary interplate coupling on the east subducting boundary to the Pacific Plate and the west collision boundary to the Amurian Plate. Using elastic dislocation theory, we inverted horizontal and vertical velocities of 212 GPS stations to estimate interplate coupling on both boundaries. The estimated coupling during 1995–2002 is spatially heterogeneous, however, it is temporally almost constant except for the region around the 1993 and 1994 earthquakes. After-slip of the 1994 earthquake occurred over the coseismic rupture area and its downdip extension on the plate boundary for 0.3–1.3 yr after the earthquake. After-slip continued only in the downdip extension for later periods and decayed with time. Weak coupling was recovered in the eastern part of the coseismic rupture area 3.3 yr after the earthquake. Interplate coupling on the Pacific Plate was strong in two regions, Miyagi-Oki and Tokachi-Oki. The west plate boundary is tightly coupled except for the source areas of three large earthquakes that occurred in 1964, 1983 and 1993. The apparent decoupling of the source areas of these earthquakes implies long-term post-seismic deformation as a result of viscoelastic relaxation in the subseismogenic lithosphere.
Ionizing irradiation grafting of natural polymers having applications in wastewater treatment

In this chapter, graft copolymerization of acrylamide onto starch induced by simultaneous electron beam irradiation as free radical initiator without additional chemicals was performed. The results showed that the level of grafting was influenced by the monomer-to-starch ratio and less by the irradiation dose. Flocculation performances of the synthesized copolymers were evaluated in coagulation-flocculation experiments at laboratory scale in order to remove the organic load of wastewater from the meat industry. Thus, in coagulation-flocculation process the copolymer aqueous solutions showed good efficiency to improve different water quality indicators (total suspended solids, chemical oxygen demand and fatty maters) as a function of the irradiation dose and copolymer dosage used as a flocculant. Hence, starch-graft copolymers having good flocculating ability can be rapidly produced with good yields by simultaneous electron beam irradiation with low doses and no additional chemicals.

Preparation of Functionalized Nanofibers and Their Applications

Recently, nano-scaled materials have been investigated with amazing increased interest due to their many advantages, such as large surface area and many active surface sites. Among different nano-scaled materials, nanofibers have been widely applied in industry due to the ease in production processes compared to other nano-materials. Nanofibers can be identified as fibers having diameters between tens and hundreds of nanometers. This nanoscaled diameter of fibers can give an enormous surface area per unit mass. Nanofibers are usually fabricated by the electrospinning method as a non-woven mat. Nonwoven fabrics are textile materials consisting of randomly oriented fibers connected together by physical entanglements or bonds between individual fibers, without any knitting or stitching. These non-woven nanofibers are the primary alternative for traditional textiles as filtration media, energy storage media, hygienic and health/personal care textiles, thermal and sound insulating materials, ecological materials, building materials, geo-textiles and automotive textiles.
Vehicle Detection Based on Semantic-Context Enhancement for High-Resolution SAR Images in Complex Background

Small-scale target detection (such as vehicles) in complex synthetic aperture radar (SAR) image scenes has always been a pain point for the advanced convolutional neural network (CNN)-based target detectors because of the downsampling operations and the local receptive field characteristics of CNNs. To tackle these limitations, a vehicle detector named SCEDet for the small-scale vehicles in SAR images is proposed to improve the detection performance in this letter. SCEDet mainly consists of two parts: subaperture semantic feature extraction and subaperture semantic-context enhancement (SCE) with SCE module. First, ResNet34 with subaperture decomposition is used to efficiently exploit the latent subaperture semantic features. Then, the SCE module is proposed to balance the multiscale semantic information as well as aggregate the global context information for vehicle detection with a small number of parameters and computation costs. The experimental results on the FARAD dataset (0.1 m $\times0.1$ m, Ka-band) demonstrate that both the detection performance and the speed are much better than other detection methods under the same hardware conditions.
Self-Compassion as a Mediator Between Perfectionism and Life-Satisfaction Among University Students

Using a correlational method, this study investigates the mediation role of self-compassion in the relationship between perfectionism dimensions and life satisfaction among university students. A sample of 246 students (171 females and 75 males, M = 21.40 years, SD = 2.02) from several universities participated in the study. Turkish versions of the Almost Perfect Scale-Revised, the Self-Compassion Scale, and the Satisfaction with Life Scale were used as data collection tools. Using structural equation modeling, the results show that self-compassion fully mediates the relationship between maladaptive perfectionism and life-satisfaction. On the other hand, there is no significant relationship between adaptive perfectionism and life-satisfaction. The Bootstrap Method that was used to assess the magnitude of the indirect effects indicates that the indirect effect of self-compassion on the relationship between maladaptive perfectionism and life-satisfaction is significant. The implications of these findings for research and practice are discussed in line with the related literature.
Sea-ice models for climate study: retrospective and new directions

Abstract Scientific observations of sea ice began more than a century ago, but detailed sea-ice models appeared only in the latter half of the last century. The high albedo of sea ice is critical for the Earth’s heat balance, and ice motion across the ocean’s surface transports fresh water and salt. The basic components in a complete sea-ice model must include vertical thermodynamics and horizontal dynamics, including a constitutive relation for the ice, advection and deformational processes. This overview surveys topics in sea-ice modeling from the global climate modeling perspective, emphasizing work that significantly advanced the state of the art and highlighting promising new developments.
Search space analysis of combinatorial problems : a case study

It is common in the literature on combinatorial problems for algorithm designers to state the selection of heuristic components without motivating them. Providing such a motivation is not an easy task. Sometimes motivation is based on historical success of a heuristic for “similar” problems, assuming that its effectiveness remains constant for the observed changes in problem structure. We provide arguments for approaching the problem of motivating algorithmic component selection by studying the combinatorial properties of the optimization problem at hand. This analysis will make the design process more rational and therefore provide the designer with a better level of support for his or her decision as to which components to introduce. Without making any claim on completeness or resulting argument strength, we believe that following this process will generally be beneficial for heuristic quality, as it can identify (in-)effective solution strategies early in the algorithm design phase, based on the problem characteristics. In this contribution we illustrate such an analysis by applying it on the search space of the city Bike Request Scheduling Problem (BRSP), which is a NP hard problem in the context of bicycle repositioning.
Optimizing the SiC Plasma Etching Process For Manufacturing Power Devices

In this research, we optimized SiC trench etching using an ICP etching system in order to improve the problems of low SiC etching rate, low selectivity (SiC/SiO2), and micro-trenches. The ICP etching system we used was a Samco Model RIE-600iP, which was specifically developed for the purpose of etching SiC. For this SiC trench etching study, we used SF6, O2, and Ar process gases. After verifying that adjusting the process parameters affected the SiC trench etching results, it became clear that we could improve the SiC etching rate by adjusting the bias power, prevent micro-trench generation by adjusting the space between the electrodes (electrode gap), and improve selectivity (SiC/SiO2) by adjusting the process pressure. In doing so, we were able to improve the major problems of SiC trench etching. By adjusting the various parameters and optimizing the SiC trench etch, we were able to achieve an etching rate of 775 nm/min, a selectivity of 13.4 (SiC/SiO2), and a desirable etching shape without micro-trenches.
Comparative Study on the Environmental Impact of Traditional Clay Bricks Mixed with Organic Waste Using Life Cycle Analysis

The construction industry is responsible for 40–45% of primary energy consumption in Europe. Therefore, it is essential to find new materials with a lower environmental impact to achieve sustainable buildings. The objective of this study was to carry out the life cycle analysis (LCA) to evaluate the environmental impacts of baked clay bricks incorporating organic waste. The scope of this comparative study of LCA covers cradle to gate and involves the extraction of clay and organic waste from the brick, transport, crushing, modelling, drying and cooking. Local sustainability within a circular economy strategy is used as a laboratory test. The energy used during the cooking process of the bricks modified with organic waste, the gas emission concentrate and the emission factors are quantified experimentally in the laboratory. Potential environmental impacts are analysed and compared using the ReCiPe midpoint LCA method using SimaPro 8.0. 5.13. These results achieved from this method are compared with those obtained with a second method—Impact 2002+ v2.12. The results of LCA show that the incorporation of organic waste in bricks is favourable from an environmental point of view and is a promising alternative approach in terms of environmental impacts, as it leads to a decrease of 15–20% in all the impact categories studied. Therefore, the suitability of the use of organic additives in clay bricks was confirmed, as this addition was shown to improve their efficiency and sustainability, thus reducing the environmental impact.
AN AUTOMATED NEGOTIATION SYSTEM WITH AUTONOMOUS AGENTS FOR A TRAVEL AGENCY BUSINESS MODEL Ş erban

The article develops an automated negotiation environment, in which cognitive agents negotiate on behalf of humans. In order to have an efficient negotiation, the agents employ different bargaining strategies. As more negotiations are taking place, the agents can change their preferences for a certain attribute of the negotiation object. The multi-agent system is applied for a travel agency business model, in which buyer agents represent persons or companies, searching for hotel rooms, and seller agents are used by the travel agency.

Spider-Jerusalem at SemEval-2019 Task 04: Hyperpartisan News Detection

This paper describes our system for detecting hyperpartisan news articles, which was submitted for the shared task in SemEval 2019 on Hyperpartisan News Detection. We developed a Support Vector Machine (SVM) model that uses TF-IDF of tokens, Language Inquiry and Word Count (LIWC) features, and structural features such as number of paragraphs and hyperlink count in an article. The model was trained on 645 articles from two classes: mainstream and hyperpartisan. Our system was ranked seventeenth out of forty two participating teams in the binary classiﬁcation task with an accuracy score of 0.742 on the blind test set (the accuracy of the top ranked system was 0.822). We provide a detailed description of our preprocessing steps, discussion of our experiments using different combinations of features, and analysis of our results and prediction errors.
Decoherence of rotational degrees of freedom

The mechanism of decoherence for a quantum system with rotational degrees of freedom is studied. From a simple model of elastic scattering, we show that the non-diagonal density matrix elements of the system exponentially decay. The decay rate depends on the difference of scattering amplitudes for different rotational configurations, leading to the gradual loss of quantum coherence between the pointer states in the system orientational space. For a dielectric ellipsoid immersed in a photon-gas environment (assuming no absorption), the decay rate is found to be proportional to the seventh power of the temperature. For an ellipsoidal object interacting with mass particles, the decay rate is proportional to the 5/2 power of the temperature. Both are different from the case of translational decoherence induced by the same environment scattering. For photon scattering, the coherence time in the rotational degrees of freedom is shown to be much shorter than that in the translational degrees of freedom.
Exploring cosmic origins with CORE: The instrument

We describe a space-borne, multi-band, multi-beam polarimeter aiming at a precise and accurate measurement of the polarization of the Cosmic Microwave Background. The instrument is optimized to be compatible with the strict budget requirements of a medium-size space mission within the Cosmic Vision Programme of the European Space Agency. The instrument has no moving parts, and uses arrays of diffraction-limited Kinetic Inductance Detectors to cover the frequency range from 60 GHz to 600 GHz in 19 wide bands, in the focal plane of a 1.2 m aperture telescope cooled at 40 K, allowing for an accurate extraction of the CMB signal from polarized foreground emission. The projected CMB polarization survey sensitivity of this instrument, after foregrounds removal, is 1.7 μK⋅arcmin. The design is robust enough to allow, if needed, a downscoped version of the instrument covering the 100 GHz to 600 GHz range with a 0.8 m aperture telescope cooled at 85 K, with a projected CMB polarization survey sensitivity of 3.2 μK⋅arcmin.
Influence of Seaweed (Padina antrillarum) Extract Foliar Application on Growth and Flowering of Roses Variety ‘Local’

The Seaweed (Padina antrillarum) abundantly found in the coastal region of Eastern Sri Lanka. Seaweed contains a wide range of nutrients and hormones for plant growth. An experiment was conducted at the Crop Farm, Eastern University, Sri Lanka to assess the effects of seaweed (Padina antrillarum) extract on the flowering of roses var. ‘Local’ from July to September 2020. Four treatments were used in this experiment viz. 10% (T1), 20% (T2), and 30% (T3) seaweed extracts with control treatment (T4). Treatments were applied at once-a-week interval. The experimental design was a completely randomized design with three replications. All other management practices were followed uniformly. Measurements were done at once a month. Collected data were analyzed. The higher performances in measured parameters (plant height, leaf area, plant biomass, number of flowers per plant) were observed in T2. It showed that once a week application of 20% seaweed liquid extract had the potential to increase growth and flower production in roses. It might be due to the presence of nutrients and the growth hormones in seaweed extract and optimum concentration of seaweed extract received by plants at T2. In T1 and T3, plants received sub-optimum and higher concentration respectively. It could be the reason for the lowest performances in these treatments. From this experiment, it could be concluded that once a week application of 20% seaweed liquid extract of Padina antrillarum is suitable to increase flowering in roses of treatment tested.
Mortality shifts and mortality compression. The case of Norway, 1900-2060

Historically, official Norwegian mortality projections computed by Statistics Norway have consistently under-predicted life expectancy. The projected age distribution of deaths may be used to check if the official mortality projections are plausible. The aim of the paper is to verify whether the projections predict a continuation of the ongoing compression in mortality and of the steady upward shift in the ages at which people die. We use official period data on observed (1900-2015) and projected (2016- 2060) sex- and age-specific mortality to estimate the age distribution of life table deaths. We analyse trends in life expectancy at birth, modal and median ages at death, and standard deviation of the age distribution at ages > 30. The historical shifts towards longer longevity are projected to continue into the future. The projections suggest a steady increase in the modal and the median age at death for men and women towards values between 90 and 94 years in 2060. At present these ages are in the range 83-90 years. Simultaneously, deaths become more concentrated around the mean, as the standard deviation of the age distribution is projected to fall continuously. Statistics Norway’s projection methodology is capable of tracking ongoing processes of mortality shifts towards higher ages and a compression of mortality around the modal and mean ages. Mortality projections could potentially benefit from including assessments of the age distribution of deaths.
Effect of Degassing Treatment on the Interfacial Reaction of Molten Aluminum and Solid Steel

The gas porosity is one of the most serious problems in the casting of aluminum. There are several degassing methods that have been studied. During smelting of aluminum, the intermetallic compound (IMC) may be formed at the interface between molten aluminum and solid steel of crucible furnace lining. In this study, the effect of degassing treatment on the formations of IMC has been investigated. The rectangular substrate specimens were immersed in a molten aluminum bath. The holding times of the substrate immersions were in the range from 300 s to 1500 s. Two degassing treatments, argon degassing and hexachloroethane tablet degassing, were conducted to investigate their effect on the IMC formation. The IMC was examined under scanning electron microscope with EDX attachment. The thickness of the IMC layer increased with increasing immersion time for all treatments. Due to the high content of hydrogen, substrate specimens immersed in molten aluminum without degasser had IMC layer which was thicker than others. Argon degassing treatment was more effective than tablet degassing to reduce the IMC growth. Furthermore, the hard and brittle phase of IMC, FeAl 3 , was formed dominantly in specimens immersed for 900 s without degasser while in argon and tablet degasser specimens, it was formed partially.
