Disentangled Representations Learning for Multi-target Cross-domain Recommendation

Data sparsity has been a long-standing issue for accurate and trustworthy recommendation systems (RS). To alleviate the problem, many researchers pay much attention to cross-domain recommendation (CDR), which aims at transferring rich knowledge from related source domains to enhance the recommendation performance of sparse target domain. To reach the knowledge transferring purpose, recent CDR works always focus on designing different pairwise directed or undirected information transferring strategies between source and target domains. However, such pairwise transferring idea is difficult to adapt to multi-target CDR scenarios directly, e.g., transferring knowledge between multiple domains and improving their performance simultaneously, as such strategies may lead the following issues: (1) When the number of domains increases, the number of transferring modules will grow exponentially, which causes heavy computation complexity. (2) A single pairwise transferring module could only capture the relevant information of two domains, but ignores the correlated information of other domains, which may limit the transferring effectiveness. (3) When a sparse domain serves as the source domain during the pairwise transferring, it would easily leads the negative transfer problem, and the untrustworthy information may hurt the target domain recommendation performance. In this article, we consider the key challenge of the multi-target CDR task: How to identify the most valuable trustworthy information over multiple domains and transfer such information efficiently to avoid the negative transfer problem? To fulfill the above challenge, we propose a novel end-to-end model termed as DR-MTCDR, standing for Disentangled Representations learning for Multi-Target CDR. DR-MTCDR aims at transferring the trustworthy domain-shared information across domains, which has the two major advantages in both efficiency and effectiveness: (1) For efficiency, DR-MTCDR utilizes a unified module on all domains to capture disentangled domain-shared information and domain-specific information, which could support all domain recommendation and be insensitive to the number of domains. (2) For effectiveness, based on the disentangled domain-shared and domain-specific information, DR-MTCDR has the capability to lead positive effect and make trustworthy recommendation for each domain. Empirical evaluations on datasets from both public datasets and real-world large-scale financial datasets have shown that the proposed framework outperforms other state-of-the-art baselines.
MJO Signals in Latent Heating: Results from TRMM Retrievals

Abstract Four Tropical Rainfall Measuring Mission (TRMM) datasets of latent heating were diagnosed for signals in the Madden–Julian oscillation (MJO). In all four datasets, vertical structures of latent heating are dominated by two components—one deep with its peak above the melting level and one shallow with its peak below. Profiles of the two components are nearly ubiquitous in longitude, allowing a separation of the vertical and zonal/temporal variations when the latitudinal dependence is not considered. All four datasets exhibit robust MJO spectral signals in the deep component as eastward propagating spectral peaks centered at a period of 50 days and zonal wavenumber 1, well distinguished from lower- and higher-frequency power and much stronger than the corresponding westward power. The shallow component shows similar but slightly less robust MJO spectral peaks. MJO signals were further extracted from a combination of bandpass (30–90 day) filtered deep and shallow components.

The Monstrous Feminine: Minnette Vári's Chimera (White Edition) (2001) and the Voortrekker Monument

Abstract For her artwork Chimera (White Edition) (2001), Minnette Vári digitally recorded the panels of the Hall of Heroes found within the Voortrekker Monument and later edited the footage, inserting her own body within these scenes while performing as the mythological Chimera. In so doing, she constructs a hybrid monstrous figure which merges in part with the existing relief sculpture while simultaneously disrupting it. Through Chimera (White Edition) the artist draws a parallel between the Chimera of Greek mythology— the fire-breathing she-monster comprised of a lion's head, goat's body, and dragon's tail—and the monstrosity that is South Africa's political legacy. Moreover, the term “chimera” has come to describe anything which may be perceived as wildly imaginative or implausible. The work then also comments on the racial biases imbued within representations of the Great Trek on the walls of the Voortrekker Monument and the ideologised portrayal of this event as an ode to Afrikaner nationalism. In this article I discuss how, in parodying classical mythology and deploying self-representation, Vári critically addresses her gender and racial identity in a post-apartheid context. I examine whether her representations subvert traditionalist notions of South African femininity, particularly the volksmoeder (mother of the nation) model. I suggest it is a patriarchal construct which Chimera (White Edition) effectively unsettles by means of the monstrous feminine trope.
Morphological origin for the stratification of P3HT:PCBM blend film studied by neutron reflectometry

Understanding the origin for the film stratification of electron donor/acceptor blend is crucial for high efficiency organic photovoltaic cell. In this study, P3HT:PCBM blend is deposited onto hydrophilic and hydrophobic substrate to examine the film stratifications. The neutron reflectivity results show that, on the different surfaces, PCBM diffuses toward the two interfacial regions in an identical fashion during thermal annealing. This evidences that the film stratification is not affected by the substrates. Instead, since P3HT remains more amorphous in the interfacial regions and PCBM is miscible with amorphous P3HT, PCBM preferentially diffuses to the interfacial regions, resulting in the stratification.
Id2 GABAergic interneurons comprise a neglected fourth major group of cortical inhibitory cells

Cortical GABAergic interneurons (INs) represent a diverse population of mainly locally projecting cells that provide specialized forms of inhibition to pyramidal neurons and other INs. Most recent work on INs has focused on subtypes distinguished by expression of Parvalbumin (PV), Somatostatin (SST), or Vasoactive Intestinal Peptide (VIP). However, a fourth group that includes neurogliaform cells (NGFCs) has been less well characterized due to a lack of genetic tools. Here, we show that these INs can be accessed experimentally using intersectional genetics with the gene Id2. We find that outside of layer 1 (L1), the majority of Id2 INs are NGFCs that express high levels of neuropeptide Y (NPY) and exhibit a late-spiking firing pattern, with extensive local connectivity. While much sparser, non-NGFC Id2 INs had more variable properties, with most cells corresponding to a diverse group of INs that strongly expresses the neuropeptide CCK. In vivo, using silicon probe recordings, we observed several distinguishing aspects of NGFC activity, including a strong rebound in activity immediately following the cortical down state during NREM sleep. Our study provides insights into IN diversity and NGFC distribution and properties, and outlines an intersectional genetics approach for further study of this underappreciated group of INs.
Massively parallel characterization of insulator activity across the genome

Insulators are cis-regulatory sequences (CRSs) that can block enhancers from activating target promoters or act as barriers to block the spread of heterochromatin. Their name derives from their ability to ‘insulate’ transgenes from genomic position effects, an important function in gene therapy and biotechnology applications that require high levels of sustained transgene expression. In theory, flanking transgenes with insulators protects them from position effects, but in practice, efforts to insulate transgenes meet with mixed success because the contextual requirements for insulator function in the genome are not well understood. A key question is whether insulators are modular elements that can function anywhere in the genome or whether they are adapted to function only in certain genomic locations. To distinguish between these two possibilities we developed MPIRE (Massively Parallel Integrated Regulatory Elements) and used it to measure the effects of three insulators (A2, cHS4, ALOXE3) and their mutants at thousands of locations across the genome. Our results show that each insulator functions in only a small number of genomic locations, and that insulator function depends on the sequence motifs that comprise each insulator. All three insulators can block enhancers in the genome, but specificity arises because each insulator blocks enhancers that are bound by different sets of transcription factors. All three insulators can block enhancers in the genome, but only ALOXE3 can act as a heterochromatin barrier. We conclude that insulator function is highly context dependent and that MPIRE is a robust and systematic method for revealing the context dependencies of insulators and other cis-regulatory elements across the genome.
The telomere-to-telomere, gapless, phased diploid genome and methylome of the green alga Scenedesmus obliquus UTEX 3031 reveals significant heterozygosity and functional separation of the haplotypes

Recent advances in sequencing technologies have improved contiguity of de novo genome assemblies. Nevertheless, the genomes of all eukaryotic organisms which are polyploid remain unfinished, limiting understanding of genetic and structural variation in diploid or polyploid organisms. Herein, we report the methodology and analysis of a 100% complete, gapless, phased, telomere-to-telomere diploid genome assembly of the eukaryote, Scenedesmus obliquus UTEX 3031 (DOE0152Z). Analysis of the fully assembled and resolved haplotypes revealed significant genomic rearrangements. Inter-haplotype heterogeneity was significant on most chromosomes yet one chromosome pair (Chromosome 15) was found to contain nearly no heterozygosity. Analysis of the 5mC methylation patterns revealed divergence in active gene content across haplotypes. Assembly of fully resolved chromosome pairs enabled complete resolution of genomic rearrangements and heterogeneity of haplotypes, the genomic basis of trait gain/loss, and evolutionary divergence across chromosome pairs. Further, when combined with 5mC methylation patterns, the assembly provides critical annotation information for genetic engineering approaches to achieve full knock-outs in allelic pairs.
XI. An essay towards the calculus of functions. Part II

In a former Paper which the Royal Society honoured with a place in the last Volume of their Transactions, I endeavoured to explain the nature of the calculus of functions, and I proposed means of solving a variety of functional equations containing only one variable quantity. My subsequent enquiries have produced several new methods of solving these, and much more complicated functional equations, and have convinced me of the importance of the calculus, particularly as an instrument of discovery in the more difficult branches of analysis; nor is it only in the recesses of this abstract science, that its advantages will be felt: it is peculiarly adapted to the discovery of those laws of action by which one particle of matter attracts or repels another of the same or of a different species; consequently, it may be applied to every branch of natural philosophy, where the object is to discover by calculation from the results of experiment, the laws which regulate the action of the ultimate particles of bodies. To the accomplishment of these desirable purposes, it must be confessed that it is in its present state unequal; but should the labours of future enquirers give to it that perfection, which other methods of investigation have attained, it is not too much to hope, that its maturer age shall unveil the hidden laws which govern the phenomena of magnetic, electric, or even of chemical action. When functional equations containing two or more variables occur, their solution presents still greater difficulties than those we have already considered; the new relations which arise, necessarily require a new notation to distinguish them. I shall endeavour, as far as I am able, to apply or extend that already in use; but, as it is almost impossible in the infancy of a calculus to foresee the extent to which it may be carried, or the new views which it may be necessary to take of it, the notation I have used should only be considered as of a temporary nature; it may be employed until some more convenient one be devised: perhaps, how ever, it might be more advantageous that it should not be altered until our acquaintance with this subject becomes more intimate, and until the infinitely varied and comprehensive relations displayed in the doctrine of functions, have been more minutely examined.
Frequency Domain Gaussian Process Models for H∞ Uncertainties

Complex-valued Gaussian processes are used in Bayesian frequency-domain system identification as prior models for regression. If each realization of such a process were an $H_\infty$ function with probability one, then the same model could be used for probabilistic robust control, allowing for robustly safe learning. We investigate sufficient conditions for a general complex-domain Gaussian process to have this property. For the special case of processes whose Hermitian covariance is stationary, we provide an explicit parameterization of the covariance structure in terms of a summable sequence of nonnegative numbers.
Discrete-time renewal input queue with balking and multiple working vacations

This paper analyzes a discrete-time finite buffer GI/Geo/1 queue with multiple working vacations wherein the customers may balk due to impatience. The service times during working vacation and vacation times are assumed to be geometrically distributed. Embedded Markov chain and supplementary variable techniques have been adopted to obtain the steady-state system length distributions at pre-arrival and arbitrary epochs, respectively. Various performance measures of the model and waiting-time distribution are also presented. A variety of numerical results showing the effect of model parameters on key performance measures are demonstrated.
Analysis of a 4f-5g supermultiplet of Fe II around 1 μm

The Fourier-transform spectrum from an iron-neon hollow-cathode lamp has been studied in the region 9000-11 000 A. The 3d6(5D)5g subconfiguration of Fe II has been established by means of about 220 newly identified 4f-5g transitions. The 5g configuration is well represented by J K coupling, which is demonstrated by the application of the quadrupolic approximation. A consistent pattern in the FWHM for various types of Fe II transitions has been observed. Calculated oscillator strengths are given for all observed lines and their relative accuracy is estimated from observed intensities. The new data offer unprecedented tools for diagnostics of stellar atmospheres.
On generalized Lax equation of the Lax triple of KP Hierarchy

In terms of the operator Nambu 3-bracket and the Lax pair (L, Bn) of the KP hierarchy, we propose the generalized Lax equation with respect to the Lax triple (L, Bn, Bm). The intriguing results are that we derive the KP equation and another integrable equation in the KP hierarchy from the generalized Lax equation with the different Lax triples (L, Bn, Bm). Furthermore we derive some no integrable evolution equations and present their single soliton solutions.
Investigations on the Effect of Backward-Facing and Forward-Facing Steps on Turbulent Mixed-Convection Flow Over a Flat Plate

The effects of backward-facing and forward-facing steps on a turbulent buoyancy-dominated mixed-convection flow over a flat plate are examined experimentally. Air velocity and temperature distributions and their turbulent fluctuations are measured simultaneously by using a two-component laser-Doppler velocimeter and a cold wire anemometer, respectively. The experiment was carried out for a step (backward-facing/forward-facing) height of 22 mm, a temperature difference, ΔT, of 30°C between the heated walls and the free-stream air (corresponding to a local Grashof number Gr xi = 6.45 × 1010), and a free-stream velocity of 0.48 m/s. It was found that the introduction of backward- and forward-facing steps increases the turbulence intensity of the velocity and temperature fluctuations downstream of the step. The present results also reveal that the maximum local Nusselt number occurs in the vicinity of the reattachment zone, and it is approximately twice for the case of the backward-facing step and three times for the case of the forward-facing step than that of the flat plate value at similar flow and thermal conditions.
Low-cost fabrication of submicron all polymer field effect transistors

All polymer field effect transistors have been fabricated combining nanoimprint lithography and inkjet printing. Trenches with hydrophilic bottoms confined by hydrophobic walls with considerable height are patterned by nanoimprint lithography. Conducting polymer solutions were then delivered into these trench liquid containers by inkjet printing. Dried conducting polymer in nearby trenches forms source-drain electrodes with the channel length accurately defined by the gap in between the designed two trenches. Top-gate all polymer field effect transistors with submicron channel lengths were successfully realized by such low-cost process.
A wideband Quasi-Yagi antenna with arrow-shaped dipoles for digital TV band applications

This paper presents the design and implementation of a novel Quasi-Yagi antenna with arrow-shaped driven element and a director for DTV applications. The proposed antenna has three resonant frequencies in the operating frequency band. Both simulation and measurement results show that the operating frequency bandwidth of the antenna for S11 < −10 dB covers the DTV band (490–798 MHz), and the relative bandwidth is 48%. Far field measurements in azimuth plane and elevation plane show that the radiation patterns are stable and end-fire within the DTV band at frequencies of 530, 666 and 754 MHz.

For each type of model, a brief overview of the papers surveyed and their relation to each other is provided.
A Human-readable Explanation for the Similarity of RDF Resources

Evaluating the similarity of RDF resources is nowadays a thoroughly investigated research problem, with reference to a variety of contexts. In fact, several tools are available for the comparison of pairs and/or groups of resources in a knowledge graph, mostly based on machine learning techniques. Unfortunately such tools, though extensively tested and fully scalable, return non-explainable (often numerical) similarity results also when comparing RDF resources, treating them according to their vector embeddings. and making no use of the semantic information carried by RDF triples. In this work, we propose a tool able to compute the commonalities of compared resource and explain them through a text in English, produced by a Natural Language Generation approach. The proposed approach is logic-based and is grounded on the computation of the Least Common Subsumer (re)defined in RDF. The feasibility of the tool is demonstrated with reference to the similarity of Twitter accounts.
Aggregation bias in wage rigidity estimation

I argue in this paper that the estimation of wage rigidity using country level data suffers from aggregation bias. Using European data for the years 2000-2017, I ﬁnd that wages respond less ﬂexibly to changes in unemployment at the regional level, compared to estimation using the same data aggregated at the country level. A possible explanation is that in the European data changes in aggregate unemployment tend to be driven by regions with low unemployment rates, while unemployment in regions with high unemployment rates is less variable and less responsive to aggregate shocks. The relationship between unemployment and wages —the wage curve— is downward sloping and convex. Due to this nonlinearity, the higher variability in lower regional unemployment rates implies higher observed wage ﬂexibility at the aggregate country level, and biased inference. The implication is that wages are even less responsive to changes in unemployment than is observed in aggregate data and commonly assumed in macro-economic models, such that for example ﬁscal stimulus would lead to less wage inﬂation than anticipated.
Metal-Organic Framework Adsorbent Materials in HVAC Systems: General Survey and Theoretical Assessment

In this paper, the use of Metal-Organic Framework (MOF) materials as an option for the energy efficiency enhancement of HVAC systems is investigated. In particular, the possibility of using MOFs as dehumidifying materials to reduce the latent load associated with the moisture content of the airflows is studied. A literature review is proposed, highlighting the benefits of using MOFs instead of other adsorbents (e.g., silica-gel) and discussing the unique features (high water uptake capacity and low regeneration temperatures) that make MOFs a preferential desiccant. The possibility to finely tune these properties is also underlined, reporting some explicative examples. A theoretical proposal of a psychrometric transformation, to be performed in a HVAC system equipped with a MOF-Assisted Dehumidifier (MAD), is presented. This transformation is compared with a traditional one (cooling and dehumidification operated by a cooling coil with low temperatures of the coolant). The preliminary numerical simulations, conducted on a reference case study in Florence, Italy, show an estimated energy saving of 30–50%, leading us to consider the use of this technology as a very competitive one in the air-conditioning sector.
Sparse Modeling of Dictionary Learning in Compressive Sensing for Medical Images

Compressive sensing of images encompasses the following stage processes: Representation of sparse signal, constructing the linear measurement and reconstructing of the image. This paper, presents the novelty of representing the sparse signal based on dictionary learning method. The choice of designing the dictionary model based on deep learning methodology, which delivers a simple and expressive structure for designing well-organized and efficient dictionaries. The norm-difference of the image is used of evaluating the performance of dictionary learning based algorithms. Experimental result shows that the Orthogonal matching pursuit (OMP) performance has better output when compared to Least Angle Regression (LAR) algorithm. The result indicates that the sparse modelling using dictionary learning with Orthogonal Matching Pursuit is proficient in CS of MRI images.
