Unraveling ML Models of Emotion With NOVA: Multi-Level Explainable AI for Non-Experts

In this article, we introduce a next-generation annotation tool called NOVA for emotional behaviour analysis, which implements a workflow that interactively incorporates the ‘human in the loop’. A main aspect of NOVA is the possibility of applying semi-supervised active learning where Machine Learning techniques are used already during the annotation process by giving the possibility to pre-label data automatically. Furthermore, NOVA implements recent eXplainable AI (XAI) techniques to provide users with both, a confidence value of the automatically predicted annotations, as well as visual explanations. We investigate how such techniques can assist non-experts in terms of trust, perceived self-efficacy, cognitive workload as well as creating correct mental models about the system by conducting a user study with 53 participants. The results show that NOVA can easily be used by non-experts and lead to a high computer self-efficacy. Furthermore, the results indicate that XAI visualisations help users to create more correct mental models about the machine learning system compared to the baseline condition. Nevertheless, we suggest that explanations in the field of AI have to be more focused on user-needs as well as on the classification task and the model they want to explain.
Ownership Structure on Dividend Policy and Its Impact on Firm Value

The purpose of this study is to examine the effect of share ownership structure on dividend policy and its impact on firm value. Ownership structure is proxied by managerial ownership, institutional ownership, and ownership concentration. The research data were obtained from manufacturing companies listed on the Indonesia Stock Exchange (BEI) 2016-2018 using purposive sampling method of selecting samples. The results of hypothesis testing using multiple regressions indicate that institutional ownership and ownership concentration have a positive effect on dividend policy,while managerial ownership has no effect. The results also show that dividend policy has a positive effect on firm value. As predicted, profitability and leverage as control variables have an effect on dividend policy and
Formulation and Physical Evaluation Sheet Mask From Red Rice (Oryza Nivara) and Virgin Coconut Oil (Cocos Nucifera L)

Sheet Mask has been widely used by East Asians, sheet masks are generally made of non-woven fabric, paper fibers, bio-cellulose, and so on. Red rice with a slightly purplish red color is very suitable for normal to dry skin. As in the analysis of red rice content, there are protein levels, fat content, water content, vitamin C in brown rice which is very good for moisturizing the facial skin. One of the natural ingredients studied is Virgin Coconut Oil (VCO). In this study, a physical evaluation test was carried out on red rice and VCO samples. The purpose of this research is to find out what formulation produces good physical properties. Red rice was extracted coldly using 96% ethanol solvent and VCO using the fermentation method. The results of the phytochemical test of red rice extract contained flavonoids, saponins, terpenoids, and quinones. Based on research results, brown rice extract and VCO have stronger antioxidant activity compared to VCO.

Flare testing using the SOF method at Borealis Polyethylene in the summer of 2000

A study of flaring efficiency at the Borealis low-pressure plant in Stenungsund was conducted using a new patented method called Solar Occultation Flux (SOF), in combination with a new type of direct measurement of flow rate and ethylene concentration in the flare stack. The SOF method is based on the measurement of hydrocarbon concentrations over a cross-section of the emission plume. Multiplied by wind speed, this gives the flux of gas through the cross-section, i.e., the source emission in kg·s-1. In the measurements, the sun was used as the light source. An infrared FTIR spectrometer linked to a sun tracker was placed on top of a van that was driven in such a way that the sunlight shone through a cross-section of the plume being measured. From the size of the molecular fingerprints in the infrared solar spectra, the concentration of ethylene and other constituents can be calculated. The results show that the flare we studied has a good combustion efficiency of about 98% at high loads (>1100 kg·h -1), but that at low loads, which are the normal operating conditions most of the time, it has a significantly lower efficiency (50-90%). Emissions thus appear to vary between 20 and 50 kg/h irrespective of load – a result that is consistent with other long-term FTIR measurements taken outside the plant. Similar emission results were also obtained during the course of the project from a newly installed flare, so that the problem does not appear to be specific to the flare that we studied. From the measurements in this study it can be concluded that a major contributing factor in the poor efficiency is an overdose of steam at low operating loads, as a result of trying to avoid soot formation by optimizing flare combustion at high loads. The problem can presumably be solved by introducing some form of dynamic steam metering linked to combustion load, or by eliminating the presence of ethylene at low operating loads. The direct flare stack measurements show that the heating value is generally low, and that theoretically we could therefore expect poorer efficiency levels. It was not possible to demonstrate this unambiguously in the present study, however, since the steam and ethylene levels were generally covariant. Only in a few cases did we find a low efficiency at low ethylene concentration, independent of steam quantity.
Theoretical Understanding of the Reaction Mechanism of SiO2 Atomic Layer Deposition

Atomic layer deposition (ALD) is a powerful nanofabrication technique for the preparation of uniform, conformal, and ultrathin films and allows accurate control of the composition and thickness of thin films at the atomic level. To date, ALD has been used for the growth of various materials, including oxides, nitrides, sulfides, metals, elements, compound semiconductors, and organic and organic–inorganic hybrid materials. As one of the most important inorganic materials, silicon dioxide (SiO2) has been used in the fields of microelectronics, catalysis, and energy storage and conversion. Various SiO2 ALD methods have been developed, which have expanded the research and applications of ALD chemistry and technology. Recent advances concerning the reaction mechanisms of SiO2 ALD have further deepened our understanding of the surface chemistry and related catalysis in the ALD of SiO2 and other oxides. Thin films of SiO2 can be obtained by means of thermal ALD and energy-enhanced ALD. Thermal ALD of SiO2 includ.
RetinexDIP: A Unified Deep Framework for Low-Light Image Enhancement

Low-light images suffer from low contrast and unclear details, which not only reduces the available information for humans but limits the application of computer vision algorithms. Among the existing enhancement techniques, Retinex-based and learning-based methods are under the spotlight today. In this paper, we bridge the gap between the two methods. First, we propose a novel “generative” strategy for Retinex decomposition, by which the decomposition is cast as a generative problem. Second, based on the strategy, a unified deep framework is proposed to estimate the latent components and perform low-light image enhancement. Third, our method can weaken the coupling relationship between the two components while performing Retinex decomposition. Finally, the RetinexDIP performs Retinex decomposition without any external images, and the estimated illumination can be easily adjusted and is used to perform enhancement. The proposed method is compared with ten state-of-the-art algorithms on seven public datasets, and the experimental results demonstrate the superiority of our method. Code is available at: https://github.com/zhaozunjin/RetinexDIP.
Frequency Reconfigurable Filtering Dielectric Resonator Antenna With Harmonics Suppression

A filtering dielectric resonator (DR) antenna (DRA) that does not require any filtering circuits is investigated. It deploys a rectangular DR and three slots fabricated in the ground plane. The antenna is excited in the fundamental TE $^{y}_{1\delta 1}$ DRA mode and two slot modes. By making use of these three modes, two tunable radiation nulls near the edges of the passband can be obtained, giving filtering effects without the need for any filtering circuits. In this article, the design, with minor modifications of the slots, is extended to a frequency-reconfigurable filtering DRA by using varactors. Its stopband can be extended to the third harmonic. By varying the voltages of the varactors, the antenna has continuous frequency agility of 27.7% (2.15–2.84 GHz), with almost the same harmonics suppression level. The antenna has a gain of ~5.0 dBi and a rejection level of over 16.1 dB across the stopband. Its total antenna efficiency in the passband is ~81%, whereas it is generally lower than the average value of 1.8% in the stopband (up to 7.0 GHz). Compared with the reported frequency-reconfigurable filtering antennas, our design has better frequency agility, more stable filtering response, and weaker radiation in the stopband.
ALP bouncing and LDH normalization in bone metastatic castration-resistant prostate cancer patients under therapy with Enzalutamide: an exploratory analysis

Background In bone metastatic castration-resistant prostate cancer (bmCRPC) treated with Enzalutamide commonly used prostate-specific antigen (PSA) can be misleading since initial PSA-flares may occur. In other therapies, bouncing of alkaline phosphatase (ALP-bouncing) was shown to be a promising surrogate for survival outcome. Low lactate dehydrogenase (LDH) is usually associated with better outcome. We evaluated the prognostic ability of ALP-bouncing, LDH, PSA, and the combination of these markers after initiation of Enzalutamide. Methods Eighty-nine patients with bmCRPC and dynamic changes of PSA, LDH and ALP were analyzed. ALP-bouncing, an increase after therapy start followed by a decline below baseline during the first 8 weeks, LDH-normalization and PSA-decline were analyzed regarding their association with survival using Kaplan-Meier analyses and uni- and multivariate (UV and MV) Cox-regression models. Results In Kaplan-Meier analysis a PSA-decline >50%, LDH-normalization and ALP-bouncing were associated with longer median progression-free survival (PFS) with 7 [95% confidence interval (CI): 4.2–9.8] vs. 3 (2.3–3.7) months for PSA-decline (log-rank P<0.01), 6 (4.1–8) vs. 2 (1.2–2.8) for LDH-normalization (P<0.01) and 8 (0–16.3) vs. 3 (1.9–4.1) for ALP-bouncing (P=0.01). Analysis of overall survival (OS) showed similar, not for all parameters significant, results with 17 (11.7–22.3) vs. 12 (7.0–17.1) months for PSA (P=0.35), 17 (13.2–20.8) vs. 7 (5.8–8.2) for LDH-normalization (P<0.01) and 19 (7.9–30.1) vs. 12 (7.7–16.3) for ALP-bouncing (P=0.32). In UV analysis, ALP-bouncing [hazard ratio (HR): 0.5 (0.3–1.0); P=0.02], PSA-decline >50% [HR: 0.5 (0.3–0.7); P<0.01] and LDH-normalization [HR: 0.4 (0.2–0.6); P<0.01] were significantly associated with longer PFS. For OS, LDH-normalization significantly prognosticated longer survival [HR: 0.4 (0.2–0.6); P<0.01]. In MV analysis, LDH-normalization was associated with a trend towards better OS [HR: 0.5 (0.2–1.1); P=0.09]. Comparing ALP-bouncing, LDH-normalization and PSA-decline with a PSA-decline alone, Kaplan-Meier analysis showed significantly longer PFS [11 (0.2–21.8) vs. 4 (0–8.6); P=0.01] and OS [20 (17.7–22.3) vs. 8 (0.3–15.7); P=0.02] in favor of the group presenting with the beneficial dynamics of all three markers. In UV analysis, the presence of favorable changes in the three markers was significantly associated with longer PFS [HR: 0.2 (0.1–0.7); P<0.01] and OS [HR: 0.3 (0.1–0.8); P=0.02]. Conclusions ALP-bouncing and LDH-normalization may add to identification of bmCRPC-patients with favorable prognosis under Enzalutamide.
Antifungal activity of selected medicinal herbs against canine dermatophytosis

The current study was conducted to evaluate the clinical efficacy of the polyherbal combination containing Acalypha indica, Curcuma longa and common salt for the treatment canine dermatophytosis. Qualitative phytochemical screening was carried out to assess the bioactive components present in extracts of Acalypha indica and Curcuma longa. Three different polyherbal combinations were prepared in different ratios and evaluated for its efficacy. The clinical evaluation was carried out in dogs with dermatophytosis brought to Veterinary Clinical Complex, Veterinary College and Research Institute, Orathanadu. The phytochemical screening of the selected herbs revealed the presence of phytoconstituents viz. alkaloids, flavonoids, glycosides, phenols, tannins, terpenoids, and carbohydrate compounds. The clinical recovery in fungal dermatophytosis in pet animals with an application of polyherbal combination in the ratio of 7:2:1 comprising Acalypha indica, Curcuma longa and saturated salt solution for four times a day for 10 days indicated that topical therapy not only eliminates fungal infection but also control the skin problem without any side effects. Also, the polyherbal antifungal combination will be an efficient and economically affordable formulation in the field to treat dermatophyte infection in pet animals.
The chloroplast genome sequencing of two important annual Trifolium species T. alexandrinum and T. resupinatum and comparative analysis with other congeneric species

Background: Chloroplast (cp) genome of most plant species has two typical inverted-repeats (IRs) regions. However, in some species this IR structure is lost for unknown reasons and the consequence still needs to be revealed . Here, we present whole cp genome sequencing of Trifolium alexandrinum (Egyptian clover) and T. resupinatum (Persian clover) from the IR lacking clade (IRLC) . Results: Global aligning of T. alexandrinum and T. resupinatum to other eight Trifolium species revealed a large amount of rearrangement and repetitive events in these ten species. We found that IR lacking species have lower GC content and higher percentage of repetition than IR containing species. Abundant single nucleotide polymorphisms (SNPs) and insertions/deletions (In/Dels) were discovered between those two species. As hypothetical cp open reading frame (ORF) and RNA polymerase subunits severally, two genes ycf1 and rpoC2 in the cp genomes, which both contain vast repetitive sequences and high Pi values (0.6656, 0.455) between T. alexandrinum and T. resupinatum , possessed highly variation among ten Trifolium species. Thus they could greatly influence evolutionary process of Trifolium species. In addition, IR containing and IR lacking Trifolium species were estimated to split during the upper Cretaceous period, which was potentially related to the violent crustal movement and sea-land changes. Conclusions: Cp genomes of T. alexandrinum and T. resupinatum, which belong to IRLC were sequenced and annotated in present study, and compared with cp genomes of other eight Trifolium species reported previously. This valuable information will provide insight into the evolution of IR lacking species. Nevertheless, further investigating of the detailed reason of IR lacking is still challenging, but it may be related to the violent crustal movement and sea-land changes of the Cretaceous period presented in this study.
Factors Influencing Free Chloride Ion Condensation in Cement-based Materials

This work investigated the effects of NaCl soaking concentration,soaking time,curing time,soaking temperature and pore solution expression pressure on the free chloride ion condensation in pore solution of cement-based materials.The results show that free chloride ion concentration in pore solution exhibits a good linear relationship with the chloride ion concentration in soaking solutions after 56 d immersion.The free chloride ion concentration was 40% greater than that of the exposured solution when the chloride ion concentration in the exposed solution was less than 0.3 mol/L,and was slightly higher than that of the exposured solution when the chloride ion concentration in the exposed solution was greater than 0.3 mol/L.The free chloride ion concentration increased with soaking time before an immersion period of 63 d,thereafter,decreased with soaking time.The chloride ion concentration in pore solution decreased as the curing time increased.Soaking temperature and pressure did not affect free chloride ion concentration.The theoretical analyses indicated that the electric double layer and change of pore structure caused by pressure could be due to the free chloride ion condensation.
Are Women Undervalued? Board Gender Diversity and IPO Underpricing

Over the last decade, practitioners have used economic arguments to claim that board gender diversity has a positive impact on firm value. If we focus on the initial returns to U.S. firms going public over this period with bulge bracket investment bank advisors, we find evidence that investors value diversity, but this does not translate into an effect on valuation beyond the issue date. There is no difference in economic fundamentals such as higher profitability or abnormal stock market performance of firms with gender-diverse boards following the IPO. The underpricing appears to reflect recent institutional investor demand for diverse firm boards during the IPO process, possibly as a result of social pressure, an increased focus on corporate social responsibility, and the improved qualifications and experience of female board members over this period.
Nesting biology of the Australian solitary bee Paracolletes crassipes Smith (Hymenoptera: Colletidae) accords with that of the Diphaglossinae

– Discovery of an extensive nesting aggregation of Paracolletes crassipes in south-western Western Australia enabled the first study of the nesting biology of this species and its genus. Nest burrows were excavated in deep loam in a clearing in sclerophyll forest. Like New World Diphaglossinae, females of P. crassipes constructed vertically oriented brood cells with strongly curved, polished necks; larval provisions were partly liquid and partly solid; mature larvae spun cocoons with flat tops and produced a clear liquid (evidently from the Malpighian tubules) at the time of defaecation. The cocoons of P. crassipes differed from those of other diphaglossines in having solid tops and no covering of the larval faecal masses. Overall, the nesting biology tends to support the inclusion of Paracolletes in the Diphaglossinae.
Expression of HSA-MIR-155-5P and mRNA Suppressor of Cytokine Signalling 1 (SOCS1) on Plasma at Early-stage and Late-stage of Nasopharyngeal Carcinoma

Nasopharyngeal carcinoma (NPC) is a head and neck tumor with high prevalence and recurrence rate in Asia. Accurate therapy based on carcinoma pathogenesis at molecular level is urgently needed. Overexpression of hsa-miR-155-5p has been identified in various carcinomas include NPC. In previous in-silico research, hsamiR-155-5p are known to target mRNA SOCS1, as a transduction signal suppressor for gene transcription activator. This study aimed to analyze different expressions of hsa-miR-155-5p and mRNA SOCS1 on plasma patients at an early and late stage of nasopharynx carcinoma. Hsa-miR-155-5p and mRNA SOCS1 were isolated from blood sample plasma using miRCURY RNA Isolation Kit-Biofluid. cDNA synthesized using cDNA Synthesis kit II, 8-64 rxns running by PCR thermal cycler (Bio-Rad c1000), and Real-time qPCR (BioRad CFX 96) for Hsa-miR-155-5p. mRNA SOCS1 was analyzed by One-Step qRT-PCR using KAPATM SYBR® kit. Hsa-miR-155-5p expressions change was upregulated 1.13-fold (p value=0.713) on the late-stage compared to the early stage, while for mRNA SOCS1 downregulated 1.1-fold (p value=0.891) on late-stage compared with early stage. Hsa-mir-155-5p was overexpressed on late-stage nasopharynx carcinoma and aligned with mRNA SOCS1 downregulated expression, compared to early stage. Deregulation of -miR-1555p dan mRNA SOCS1 may play important role in NPC progressivity.
Impact of High Body Mass Index on The Allograft Outcomes in Kidney Transplant Recipients with Pre-Sensitization to Human Leukocyte Antigen: A Retrospective Cohort Study

Background The aim of this study was to investigate whether high body mass index (BMI) and pre-sensitization to human leukocyte antigen (HLA) in kidney transplant recipients (KTR) had a synergistic impact on the allograft outcomes.Methods From January 2010 to December 2018, 1,290 KTs were performed in Seoul St Mary's Hospital. Of these, 682 cases of ABO compatible KT were enrolled. They were divided into 4 groups (low BMI-non-sensitized, high BMI-non-sensitized, low BMI sensitized, high BMI-sensitized) according to the median BMI value (22.7 kg/m2) and HLA pre-sensitization status (HLA-DSA MFI >3,000). Short-term and long-term allograft outcomes were compared between the groups.Results The rate of late antibody mediated rejection tended to be the highest in the high BMI-sensitized group, and the decline in allograft function in the high BMI-sensitized group was higher than in the other 3 groups. Death-censored graft loss (DCGL) rates and the hazard ratio (HR) for DCGL were the highest in the high BMI-sensitized group (4/21 (19.0%), HR 4.648, P = 0.022) and a significant interaction was detected between high BMI and HLA pre-sensitization status (P value for interaction = 0.008). Conclusions Our results suggest that pre-sensitization to HLA and high BMI in KTRs might have a synergistic adverse impact on the allograft outcomes.
Equilibrium Studies for the Adsorption of Dyes on Bagasse Pith

The adsorption of four dyes on to bagasse pith has been studied. The equilibrium isotherms have been measured and analyzed using the Langmuir, Freundlich and Jossens equations and the experimental data have been compared with the theoretically predicted data. The equilibrium saturation adsorption capacities were 21.7. 22.9. 155.4 and 76.6 mg/g for Telon Blue ANL (Acid Blue 25, CI62055), Erionyl Red RS (Acid Red 114, CI23635), Astrazone Blue FRR (Basic Blue 69) and Maxilon Red BL-N (Basic Red 22, CI11055), respectively. Isotherms were measured at different temperatures and from the data the enthalpies of adsorption were determined to be 11.5, 11.8. 10.3 and 10.7 kJ/mol for Acid Blue 25, Acid Red 114, Basic Blue 60 and Basic Red 22, respectively.
