description: Click-Through Rate (CTR) prediction holds paramount significance in online advertising and recommendation scenarios. Despite the proliferation of recent CTR prediction models, the improvements in performance have remained limited, as evidenced by open-source benchmark assessments. Current researchers tend to focus on developing new models for various datasets and settings, often neglecting a crucial question: What is the key challenge that truly makes CTR prediction so demanding?
 In this paper, we approach the problem of CTR prediction from an optimization perspective. We explore the typical data characteristics and optimization statistics of CTR prediction, revealing a strong positive correlation between the top hessian eigenvalue and feature frequency. This correlation implies that frequently occurring features tend to converge towards sharp local minima, ultimately leading to suboptimal performance. Motivated by the recent advancements in sharpness-aware minimization (SAM), which considers the geometric aspects of the loss landscape during optimization, we present a dedicated optimizer crafted for CTR prediction, named Helen. Helen incorporates frequency-wise Hessian eigenvalue regularization, achieved through adaptive perturbations based on normalized feature frequencies.
 Empirical results under the open-source benchmark framework underscore Helen's effectiveness. It successfully constrains the top eigenvalue of the Hessian matrix and demonstrates a clear advantage over widely used optimization algorithms when applied to seven popular models across three public benchmark datasets on BARS. Our code locates at github.com/NUS-HPC-AI-Lab/Helen.

A cross-language comparison of vowel production and perception: language-specific and universal aspects
Creators: name: Bradlow, Ann R.
Publisher: name: Zenodo
Year: 1993

description: This paper presents a concurrent examination of the acoustic and perceptual characteristics of the vowels of two languages with very different vowel systems, namely English with a relatively large inventory of eleven stressed monophthongs and Spanish with a relatively small inventory of five stressed monophthongs. This investigation attempts to identify language-specific and universal aspects of both vowel production and perception by exploring the effect of inventory size on the acoustic and perceptual characteristics of similar vowel categories across different vowel systems. Specifically, this study investigates the acoustic characteristics of the four common vowels across the two languages, namely Iii, le/, 101, and lui, as well as the perceptual characteristics of the /u/-/ol contrast in the two languages. By looking at the phonetics of vowels that occupy similar positions in the vowel spaces of the two languages the effects of the different vowel inventory structures are most noticeable, and thus provide an indication of the language-specific and universal aspects of vowel production and perception.

description: We describe fossil kogiid periotics from the Lower Pliocene upper Bone Valley Formation in central Florida and the Lower to Upper Pliocene Yorktown Formation at Lee Creek Mine, North Carolina. The fossils show diagnostic characters that identify them as belonging to Kogiidae, such as three spines in the anterior process, presence of an incudal process, and a posterior process oriented along the long axis of the bone. Morphological comparisons and morphometric and statistical analyses of periotic proportions confirm the presence of a large and a small morphotype within the sample. The large morphotype (mean length = 39.76 mm) belongs to an unknown kogiid that occurs in both formations, whereas the small morphotype (mean length = 28.64 mm), referred to aff. Kogia sp., occurs only in the Yorktown Formation. The cooccurrence of two taxa in North Carolina may represent one of the earliest evidences of sympatry in kogiids and may demonstrate that this ecological behavior has been part of the natural history of this group at least since the deposition of the Yorktown Formation at Lee Creek (∼4.8–3.1 Ma). In addition, the occurrence of the large morphotype in the upper Bone Valley Formation, herein reported for the first time, shows that we are still far from understanding the diversity of marine mammals of that formation and that revision of newly acquired material is necessary.

description: Sour cherry (Prunus cerasus) is rich in biologically active phenolic compounds. These compounds are concentrated in fruit skin and most of them remain in the leftovers during the production of juice. Supercritical carbon dioxide extraction was used to separate phenolic compounds from sour cherry pomace. The effects of temperature, pressure and the addition of ethanol on anthocyanin and the total phenolic content and radical scavenging activity of the extracts were investigated. The best results were acquired for 35°C, 10 MPa and 80% ethanol addition. A strong correlation was found between the phenolic content and other features of the extracts.

description: The demand for non-conventional water resources has been intensified by a multifaceted set of factors, including water stress, drought, population growth, and rapid urbanization. This demand has escalated notably, particularly within the MENA region, which is home to 14 of the 17 most water-stressed nations worldwide. This issue is of pressing concern for different stakeholders. Seawater desalination is regarded as a resilient freshwater solution, yet challenges persist, including elevated energy consumption, environmental impacts, capital and operational cost constraints, and quality issues concerns. Current studies rarely address these multifaceted performance challenges. The objective of this study is twofold. Firstly, it will provide a comprehensive performance assessment tool by developing a Sustainability Balanced Scorecard (SBSC) that incorporates both traditional BSC and sustainability dimensions. Secondly, it will propose a conceptual framework suggesting the assessment of the impact of SBSC non-financial perspectives on the financial performance of desalination plants.

description: This article combines techniques from two fields of applied mathematics: optimization theory and inverse problems. We investigate a generalized conditional gradient method and its connection to an iterative shrinkage method, which has been recently proposed for solving inverse problems. The iterative shrinkage method aims at the solution of non-quadratic minimization problems where the solution is expected to have a sparse representation in a known basis. We show that it can be interpreted as a generalized conditional gradient method. We prove the convergence of this generalized method for general class of functionals, which includes non-convex functionals. This also gives a deeper understanding of the iterative shrinkage method.

description: This study investigates the toxicity of bare iron oxide nanoparticles (IONPs) and surface functionalization iron oxide nanoparticles (SF-IONPs) to the growth of freshwater microalgae Chlorella sp. This study is important due to the increased interest on the application of the magnetic responsive IONPs in various fields, such as biomedical, wastewater treatment, and microalgae harvesting. This study demonstrated that the toxicity of IONPs was mainly contributed by the indirect light shading effect from the suspending nanoparticles which is nanoparticles concentration-dependent, direct light shading effect caused by the attachment of IONPs on cell and the cell aggregation, and the oxidative stress from the internalization of IONPs into the cells. The results showed that the layer of poly(diallyldimethylammonium chloride) (PDDA) tended to mask the IONPs and hence eliminated oxidative stress toward the protein yield but it in turn tended to enhance the toxicity of IONPs by enabling the IONPs to attach on cell surfaces and cause cell aggregation. Therefore, the choice of the polymer that used for surface functionalize the IONPs is the key factor to determine the toxicity of the IONPs.

description: Thiuram disulfide intercalates of lead(II) and cadmium(II) were prepared by the reaction of binary layered metal iodides with five dithiocarbamates in air. The intercalates were characterized by elemental analysis, Powder X-ray diffraction (XRD), infrared (IR), ultraviolet–visible spectroscopy, diffuse reflectance spectroscopy, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy, high-resolution transmission electron microscopy (HRTEM), and atomic force microscopy (AFM) techniques. IR showed increased contribution of the thioureide bond and the presence of weak disulfide stretching frequency. Powder XRD showed the characteristic intermediate 2θ signal confirming the intercalation. Powder XRD clearly differentiated intercalates from the iodinated product of dithiocarbamate. As the bulkiness of substituents on disulfide increased, “d” also increased. The higher thermal stability associated with intercalates clearly suggests a strong ionic interaction and a difficult de-intercalation. SEM images of lead intercalates indicated crystalline nature. The intercalates appeared as rods or spheres. The diallyl-intercalate, [PbI2](H5C3)2NCSS-SSCN(C3H5)2 (where (H5C3)2NCSS-SSCN(C3H5)2 is diallylthiuram disulfide), shows “net like structures.” Intercalation of oxidized dithiocarbamates in the “galleries” of layered PbI2/CdI2 is observed. HRTEM and AFM analysis of intercalates showed the particles to be nano-rods.

description: A magnetic graphene nanocomposite (Fe3O4-GNC) was prepared and used for the solid phase extraction (SPE) and removal of 2,4-dichlorophenol from aqueous solutions. The physicochemical properties were investigated using SEM, EDX, FTIR, and TGA. Different factors affecting sorption capacity were studied systematically. Results for kinetics studies revealed that 2,4-dichlorophenol sorption followed pseudo-second-order kinetics and the qe value (987.45 mg/g) was in close agreement with experimental value (1000 mg/g). Thermodynamic study showed that the sorption is endothermic (∆Hº = +56.116 kJ/mol) and spontaneous. The desorption studies were carried out for the reusability and extraction of 2,4-dichlorophenol from aqueous samples and 94% recoveries were obtained. The method was found feasible for the removal and preconcentration of trace analysis of 2,4-dichlorophenol in environmental water samples.

Vowel Height Assimilation in Bantu Languages
Creators: name: Clements, G.N.
Publisher: name: Zenodo
Year: 1991

description: The aim of this paper will be to seek an improved model of vowel height for Bantu
 languages. Based on a study of several representative patterns of height assimilation, it
 will suggest that vowel height can be regarded as a uniform phonetic and phonological
 parameter, characterized in terms of a single, binary feature [open]. This approach differs both from the standard feature system discussed above, in which vowel height is described in terms of several formally unrelated features such as [high] and [low], and from alternative models in which vowel height is characterized in terms of one-valued features, also called particles (see, for example, Schane 1984). The new approach is described in the next section. The following sections apply it to several different Bantu vowel height systems, and show that it provides a straightforward account of several different types of assimilation processes, while allowing a uniform characterization of vowel height across superfically different systems.

description: The present work allows you to address the recent institutional innovations in the context of the Social Assistance system, from the perspective of the implementation of the principle of subsidiarity, where the creation of public spaces for articulation of demands need to be accompanied by initiatives aimed at preparing the public for a culture of shared management and participatory democracy. In this way, the creation of initiatives that are able to channel the demands and solve social conflicts requires the strengthening of local spheres, as well as the implementation of public action communication mechanisms able to disseminate proposals bandied about, the reconstruction of collective identities, in addition to the construction of institutional channels where the citizen can be around your ruler and above all, trust him. In addition, the decision-making spaces must be closer to the local problems, without prejudice to national or global typically issues.

description: Recommender systems often suffer from selection bias as users tend to rate their preferred items. The datasets collected under such conditions exhibit entries missing not at random and thus are not randomized-controlled trials representing the target population. To address this challenge, a doubly robust estimator and its enhanced variants have been proposed as they ensure unbiasedness when accurate imputed errors or predicted propensities are provided. However, we argue that existing estimators rely on miscalibrated imputed errors and propensity scores as they depend on rudimentary models for estimation. We provide theoretical insights into how miscalibrated imputation and propensity models may limit the effectiveness of doubly robust estimators and validate our theorems using real-world datasets. On this basis, we propose a Doubly Calibrated Estimator that involves the calibration of both the imputation and propensity models. To achieve this, we introduce calibration experts that consider different logit distributions across users. Moreover, we devise a tri-level joint learning framework, allowing the simultaneous optimization of calibration experts alongside prediction and imputation models. Through extensive experiments on real-world datasets, we demonstrate the superiority of the Doubly Calibrated Estimator in the context of debiased recommendation tasks.

description: A Magnetic-graphene nanocomposite (Fe3O4-GNC) was prepared and used for the solid phase extraction and removal of 2,4-dichlorophenol from aqueous solutions. The physico-chemical properties were investigated using SEM, EDX, FTIR and TGA. Different factors affecting sorption capacity were studied systematically. Results for kinetics studies revealed that 2,4-dichlorophenol sorption followed pseudo-second order kinetics and the qe value (987.45 mg/g) was in close agreement with experimental value (1000 mg/g). Thermodynamic study showed that the sorption is endothermic (∆Hº = +56.116 kJ mol−1) and spontaneous. The desorption studies were carried out for the reusability and extraction of 2,4-dichlorophenol from aqueous samples and 94% recoveries were obtained. The method was found feasible for the removal and preconcentration of trace analysis of 2,4-dichlorophenol in environmental water samples.

description: The Comments are devoted to the paper 'Derivation of lump solutions to a variety of Boussinesq equations with distinct dimensions' (Int J Numer Methods Heat Fluid Flow. 2022;32:3072{3082), in which three new generalizations of the classical Boussinesq equation are suggested that were further investigated in several papers. Here it is shown that the equations derived in the above paper are not presented in their canonical forms. It turns out that all three equations can be essentially simplified by the standard technique widely used for linear and quasi-linear PDEs. As a result, it is proved that the equations suggested are not multidimensional generalizations of the Boussinesq equation.

description: Background: Prior research suggests that both posttraumatic stress disorder (PTSD) and alcohol abuse affect behavioral healthcare utilization among combat-exposed military populations. However, their interactive effect is not well documented, especially after experiencing psychological trauma. Objective: This study examined the role of hazardous alcohol use (i.e. repeated patterns of drinking which lead to harmful consequences) on behavioral healthcare utilization among service members stratified by past-year combat exposure. Method: This study utilized a sample of National Guard service members who participated in an in-depth survey 2–4 months after returning from Operation Enduring Freedom, Operation Iraqi Freedom, or Operation New Dawn deployments (2011–2013) (n = 467). We examine the marginal effect (the change in the probability) of hazardous alcohol use on utilization while controlling for trauma exposure, PTSD and other potential covariates. Results: In the unadjusted logistic model, hazardous alcohol use reduced the probability of behavioral healthcare utilization by 77% among service members who had been exposed to combat within the past year. In the adjusted model, which controlled for socio-demographics (age, gender, and race), health status (PTSD symptoms, depression and physical health), and measures of stigma (perception of services as embarrassing or harmful to one's career or social networks), hazardous alcohol use further reduced the utilization probability by 302%. Conclusion/Importance: Although these findings require replication, they appear to demonstrate that when combat-exposed service members engaged in hazardous alcohol use at postdeployment, they were much less likely to utilize behavioral healthcare to manage their posttraumatic stress symptoms during this period.

description: Optimization metrics are crucial for building recommendation systems at scale. However, an effective and efficient metric for practical use remains elusive. While Top-K ranking metrics are the gold standard for optimization, they suffer from significant computational overhead. Alternatively, the more efficient accuracy and AUC metrics often fall short of capturing the true targets of recommendation tasks, leading to suboptimal performance. To overcome this dilemma, we propose a new optimization metric, Lower-Left Partial AUC (LLPAUC), which is computationally efficient like AUC but strongly correlates with Top-K ranking metrics. Compared to AUC, LLPAUC considers only the partial area under the ROC curve in the Lower-Left corner to push the optimization focus on Top-K. We provide theoretical validation of the correlation between LLPAUC and Top-K ranking metrics and demonstrate its robustness to noisy user feedback. We further design an efficient point-wise recommendation loss to maximize LLPAUC and evaluate it on three datasets, validating its effectiveness and robustness.

description: This paper attempts a probe into negative refraction without absorption by means of an incoherent pump field and a strong coherent field coupling the dense four-level atomic system.With the application of the incoherent pump field to manipulate the populations in atomic levels and the variable strong coherent field to create quantum coherence, the constraint condition of two equal transition frequencies responding to the probe field in the atomic system isn't required.And these lead to the propagation transparency and strong magnetic response of the probe field,left-handedness with vanishing absorption in the atomic system.However,an excessive coherent field intensity would increase the absorption.

description: Uncovering the causes and foundations of increasing political polarization poses a pressing open problem to all social sciences. Here, we report results from an online experiment with a representative sample of the US population, deployed the week before the 2020 US presidential election, to analyze the role of affective polarization and social identity in facilitating ideological polarization at the individual level. Participants were incentivized to predict policy-sensitive statistics a year after the election conditional on its outcome. To update their initial predictions, individuals select or exogenously obtain factually similar articles on the respective topics curated from differently slanted news sources. We employ "political groupiness'' as an empirical measure for individual susceptibility for affective polarization, using behavioral experiments from the economic literature on social identity. We find political groupiness to be systematically associated with ideological polarization, as the partisan biases in both the demand for and processing of information is significantly amplified for groupy subjects. Our results suggest that ideological polarization is founded, at least partly, in the social identity roots of partisanship. Reducing the salience of intergroup distinctions by delabeling information sources decreases the partisan bias in information demand but not in information processing.
Effect of spontaneously generated coherence on left-handedness in a degeneracy atomic system

description: A theoretical investigation is carried out into the effect of spontaneously generated coherence(SGC) on the left-handedness in a four-level Y-type atomic system with two highest nearly degenerate lying levels. It is found, with the spontaneously generated coherence intensity enhancing, the atomic system gradually displays left-handedness with simultaneous negative permittivity and permeability. And the refractive index enhances with the increasing intensity of SGC.However, the absorption is suppressed by the SGC effect when the SGC has a large intensity.When the probe field is near-resonant coupled to the atomic system, the appearance of SGC doesn't always change the permeability from positive to negative and allow for left-handed behavior,unless the SGC reaches a large intensity.
