Authors: Emedolu Blessing Obianuju , Thomas Godwin , Gurumdimma Nentawe Y.
Published: August 2023

Phishing attacks pose a significant threat in the cyber world, exploiting unsuspecting users through deceptive emails that lead them to malicious websites. To combat this challenge, various deep learning based anti-phishing techniques have been developed. However, these models often suffer from high false positive rates or lower accuracy. In this study, we evaluate the performance of two neural networks, the Autoencoder and Multilayer Perceptron (MLP), using a publicly available dataset to build an efficient phishing detection model. Feature selection was performed through correlation analysis, and the Autoencoder achieved an accuracy of 94.17%, while the MLP achieved 96%. We used hyperparameters for optimization using the Gridsearch CV, resulting in a False Positive Rate (FPR) of 1.3%, outperforming the Autoencoder’s 4.1% FPR. The MLP model was further deployed to determine the legitimacy of websites based on input URLs, demonstrating its usability in real-world scenarios. This research contributes to the development of effective phishing detection models, emphasizing the importance of optimizing neural network architecture for improved accuracy and reduced false positives
Ravulizumab (Ultomiris)
Authors: CADTH
Published: August 2023

CADTH recommends that Ultomiris should not be reimbursed by public drug plans for the treatment of adult patients with anti-acetylcholine receptor (AChR) antibody–positive generalized myasthenia gravis (gMG).

Although evidence from a clinical trial (CHAMPION) suggested that Ultomiris contributed to improvement in activities of daily living and gMG disease severity after 26 weeks, it is uncertain if immunosuppressive therapy (IST) was optimized at the time of study enrolment. Patients in both Ultomiris and placebo groups of the CHAMPION trial received stable doses of IST; however, it was unclear if IST was optimized in both groups. The eligibility criteria for duration of IST treatment and duration of stable IST dosing in the CHAMPION trial were below the estimated range of time to maximal response according to the clinical experts consulted by CADTH. Although some evidence (mean time frame since MG diagnosis, mean corticosteroid treatment durations) was available, without dose information, it is unclear if corticosteroid was optimized for patients at the time of study enrolment.

Feedback from patient and clinician groups identified an unmet need for patients with gMG who have symptoms but are not considered refractory to IST. There is an unmet need for effective therapy for patients with refractory gMG, but the CHAMPION trial did not require patients to be refractory. Therefore, it is unknown how many patients in the CHAMPION trial were refractory and if the results observed in the trial would be the same in these patients. As a result, the ability of Ultomiris to fill the unmet need for patients who are refractory to IST is limited by the CHAMPION trial design, which used Ultomiris earlier in the treatment paradigm for gMG and did not require participants to be refractory to IST.

The CHAMPION trial did not provide evidence on the efficacy or harms of Ultomiris compared with other therapies used in clinical practice, such as rituximab, IV immunoglobulin, and plasma exchange. Therefore, the potential therapeutic benefit is unknown compared to what is used in clinical practice.

Abstract. The light-absorbing organic aerosol (OA), known as brown
carbon (BrC), has important radiative impacts; however, its sources and
evolution after emission remain to be elucidated. In this study, the light
absorption at multiple wavelengths, mass spectra of OA and microphysical
properties of black carbon (BC) were characterized at a typical suburban
environment in Beijing. The absorption of BC is constrained by its size
distribution and mixing state, and the BrC absorption is obtained by
subtracting the BC absorption from the total aerosol absorption. Aerosol
absorption was further apportioned to BC, primary BrC and secondary BrC by
applying the least correlation between secondary BrC and BC. The
multilinear regression analysis on the factorized OA mass spectra indicated that the OA from traffic and biomass burning emission contributed to primary BrC. Importantly, the moderately oxygenated OA (O / C = 0.62) was revealed to
highly correlate with secondary BrC. These OA had higher nitrogen content,
in line with the nitrogen-containing functional groups detected by the
Fourier transform infrared spectrometer. The photochemical processes were
found to reduce the mass absorption cross section (MAC) of primary OA,
reducing its contribution to total absorption by 20 %, at the same time
increasing MAC for secondary OA, which showed a 30 % enhancement in
contribution to total absorbance, implying the concurrent whitening and
darkening of BrC. This provides field evidence that the photochemically
produced secondary nitrogen-containing OA can considerably compensate for some
bleaching effect on the primary BrC, hereby causing radiative impacts.

Published: August 2023

Abstract. Ground-based high resolution observations of downward longwave irradiance (DLI), surface air temperature, water vapour surface partial pressure and column amount, zenith sky infrared (IR) radiance in the atmospheric window, and all-sky camera images are regularly obtained at the Thule High Arctic Atmospheric Observatory (THAAO, 76.5° N, 68.8° W), North-West Greenland. The datasets for the years 2017 and 2018 have been used to assess the performance of different empirical formulas to infer clear sky DLI. An algorithm to identify clear sky observations has been developed, based on value, variability, and persistence of zenith sky IR radiance. Seventeen different formulas to estimate DLI have been tested against the THAAO dataset, using the originally determined coefficients. The formulas which combine information on total column water vapour and surface air temperature appear to perform better than others, with a mean bias with respect to the measured DLI smaller than 1 W/m2 and a root mean squared error (RMSE) around 6 W/m2. Some formulas, specifically developed for the Arctic, are found to produce poor statistical results; this is attributed partly to limitations in the originally used dataset, which does not cover a whole year, or is relative to very specific conditions (i.e., the ice sheet). The bias displays a significant improvement when the coefficients of the different formulas are calculated using the THAAO dataset. The presence of two full years of data allows the investigation of the inter-annual variability, and the use of different years for the determination of the coefficients and the evaluation of results. The smallest values of the bias and RMSE reach 0.1 W/m2 and 5 W/m2, respectively. Overall, best results are found for formulas which use both surface parameters and total water vapour column, and have been developed from global datasets. Conversely, formulas which express the atmospheric emissivity as a linear function of the logarithm of the column integrated water vapour appear to poorly reproduce the observations at THAAO.
Late Aptian paleoclimate reconstruction of the Brazilian equatorial margin: inferences from palynology

Published: August 2023

Abstract. This study conducted high-resolution paleoclimatic analyses based on the
identification of palynological groups of late Aptian age (biozone
Sergipea veriverrucata) in the Bragança and Codó formations within the Bragança–Viseu,
São Luís, and Parnaíba basins. The analysis comprised 40
palynological samples, with 200 palynomorphs per slide counted when
possible. Bioclimatic analysis was mainly supported by the identification of
botanical affinities, and ecological and climatic parameters such as the
wet/arid trend (Fs/X), Shannon–Wiener diversity, and indicator species
analysis (IndVal) were used. Statistical analyses such as principal
component and cluster analyses were employed to support the paleoclimatic
interpretations. The study recognized 69 genera distributed among the main
groups of living plants, including bryophytes, ferns, lycophytes,
gymnosperms, and angiosperms. It was possible to attribute botanical
affinity in 94.2 % of the taxa, and nine genera occurred in all sections
studied: Afropollis, Araucariacites, Callialasporites, Cicatricosisporites, Classopollis, Cyathidites, Deltoidospora, Equisetosporites, and Verrucosisporites, with Classopollis being the most abundant. The
stratigraphic distribution of the bioclimatic groups (hydrophytes,
hygrophytes, lowland tropical flora, upland flora, and xerophytes) allowed
for the identification of climatic phases: pre-evaporitic, evaporitic, and
post-evaporitic. In the pre-evaporitic phase, the most significant
abundances were between the hygrophytes and upland flora, indicating a
certain level of humidity. Xerophytes were the most abundant in all phases,
with a conspicuous increase in the evaporitic phase, reflecting an increase
in aridity. In the post-evaporitic phase, there was a significant increase
in the upland flora with the return of wetter conditions. This study
confirmed an increasing humidity trend in the analyzed sections, probably
owing to the influence of the Intertropical Convergence Zone that was already
operating during the late Aptian.
Plume detection and emission estimate for biomass burning plumes from TROPOMI carbon monoxide observations using APE v1.1
Authors: Goudar Manu , Anema Juliëtte C. S. , Kumar Rajesh , Borsdorff Tobias , Landgraf Jochen
Published: August 2023

Abstract. This paper presents the automated plume detection and emission estimation algorithm (APE), developed to detect CO plumes from isolated biomass burning events and to quantify the corresponding CO emission rate. APE uses the CO product of the Tropospheric Monitoring Instrument (TROPOMI) on board the Copernicus Sentinel-5 Precursor (S5P) satellite, launched in 2017, and collocated active fire data from the Visible Infrared Imaging Radiometer Suite (VIIRS), the latter flying 3 min ahead of S5P. After identifying appropriate fire events using VIIRS data, an automated plume detection algorithm based on traditional image processing algorithms selects plumes for further data interpretation. The approach is based on thresholds optimized for data over the United States in September 2020. Subsequently, the CO emission rate is estimated using the cross-sectional flux method, which requires horizontal wind fields at the plume height. Three different plume heights were considered, and the ECMWF Reanalysis v5 (ERA5) data were used to compute emissions. A varying plume height in the downwind direction based on three-dimensional Lagrangian simulation was considered appropriate. APE is verified for observations over Australia and Siberia. For all fire sources identified by VIIRS, only 16 % of the data corresponded to clear-sky TROPOMI CO data with plume signature. Furthermore, the quality filters of APE resulted in emission estimations for 26 % of the TROPOMI CO data with plume signatures. Visual filtering of the APE's output showed a true-positive confidence level of 97.7 %. Finally, we provide an estimate of the emission uncertainties. The greatest contribution of error comes from the uncertainty in Global Fire Assimilation System (GFAS) injection height that leads to emission errors <100 %, followed by systematic errors in the ERA5 wind data. The assumption of constant emission during plume formation and spatial under-sampling of CO column concentration by TROPOMI yields an error of <20 %. The randomized errors from the ensemble ERA5 wind data are found to be less than 20 % for 97 % of the cases.
Heterogeneous grain growth and vertical mass transfer within a snow layer under a temperature gradient
Authors: Bouvet Lisa , Calonne Neige , Flin Frédéric , Geindreau Christian
Published: August 2023

Abstract. Inside a snow cover, metamorphism plays a key role in snow evolution at different scales. This study focuses on the impact of temperature gradient metamorphism on a snow layer in its vertical extent. To this end, two cold-laboratory experiments were conducted to monitor a snow layer evolving under a temperature gradient of 100 K m−1 using X-ray tomography and environmental sensors. The first experiment shows that snow evolves differently in the vertical: in the end, coarser depth hoar is found in the center part of the layer, with covariance lengths about 50 % higher compared to the top and bottom areas. We show that this heterogeneous grain growth could be related to the temperature profile, to the associated crystal growth regimes, and to the local vapor supersaturation. In the second experiment, a non-disturbing sampling method was applied to enable a precise observation of the basal mass transfer in the case of dry boundary conditions. An air gap, characterized by a sharp drop in density, developed at the base and reached more than 3 mm after a month. The two reported phenomena, heterogeneous grain growth and basal mass loss, create heterogeneities in snow – in terms of density, grain and pore size, and ice morphology – from an initial homogeneous layer. Finally, we report the formation of hard depth hoar associated with an increase in specific surface area (SSA) observed in the second experiment with higher initial density. These microscale effects may strongly impact the snowpack behavior, e.g., for snow transport processes or snow mechanics.
Espectros e Mitologias na Política: uma abordagem da Ideologia Fantasma que percorre a esquerda e a direita
Authors: Barria-Asenjo Nicol A.
Published: August 2023

A história nos legou o nascimento da bifurcação entre esquerda e direita como um produto contingente da espontaneidade de uma mudança material, uma reestruturação radical da arena física na qual as decisões polí-ticas deveriam ser tomadas, o que deu origem a uma política dupla, então qual é a mudança estrutural que permitirá o nascimento de uma nova forma de fazer política em nossos tempos? Este documento introduz uma nova perspectiva crítica aos debates em torno da dicotomia entre esquerda e direita na política. Argumenta-se que participamos ativamente da condição fantasmagórica que a política mantém, uma política esvaziada de sentido e significado, que sobrevive oferecendo soluções generalizadas e desesperadas. O problema da escassa delimitação destes conceitos e a evidente mistura nos projetos políticos de nosso tempo, exige uma leitura sistematizante-documentário e uma análise filosófica das extensas propostas teóricas que tentam abordar o fenômeno. Ao analisar os usos históricos, políticos, sociais e econômicos que foram inseridos nos conceitos de esquerda e direita desde os primeiros tempos, fomos introduzidos no atoleiro da crise de legitimidade que existe na política a fim de repensar o futuro.
Unveiling The Effectiveness of Working Capital Management on Firm Performance: The Moderating Role of Firm Size

Published: August 2023

Working capital management is critical to an organization's financial health and long-term performance. The relationship between working capital management and firm performance is uncertain, and research on firm size's moderating effect is scarce. The study investigates the impact of Working capital management (WCM) on firm performance and examines how the firm size moderates this relationship. Firms must efficiently manage working capital to stay financially stable and profitable. WCM procedures affect performance differently depending on the firm size. The research is conducted using the quantitative research design. For this research, we have gathered data from the annual reports of the firms belonging to the KMI-30 index listed at the Pakistan Stock Exchange. The period considered as the research sample is from 2012 to 2022, as it can provide a better analysis of different financial crises and long-term analysis. The quantile regression was used to evaluate the research objective since the data has the issue of heteroscedasticity and autocorrelation. We found that working capital significantly and positively influences the firm performance. However, the moderating role of firm size was found to be insignificant. The findings reveal that firms of all sizes should concentrate on ensuring good working capital management strategies to increase their performance. This requires monitoring and optimizing inventory, accounts receivable, and accounts payable while assuring sufficient liquidity to satisfy operating needs.

Published: August 2023

Extensive research has been conducted in the existing literature to examine the impact of health outcomes on macroeconomic indicators. The micro-level investigation of public healthcare services, particularly utilisation, is unexplored in Pakistan. This study aims to investigate the factors that influence the utilisation of public health care services in Pakistan. The utilisation of the public health care services was determined in this study by incorporating socioeconomic, demographic, and regional covariates. Data was sourced from the PSLM survey (2019-2020) for the empirical analysis. The empirical evidence is based on the Ordered Logit model. The findings of the OLogit model indicate a positive association between literacy rate and household income with a higher likelihood of frequent and consistent utilisation of public health care services. The study confirms the existence of urban-rural disparity in utilising public health services. The findings of this study reveal a notable difference regarding the participation of the poor household in using health care services frequently or regularly. This study's findings hold considerable implications concerning the urban-rural disparity, equitable distribution of health care, and the enhancement of health care accessibility through increased purchasing power.

Authors: . Asima , Manzoor Fahim , . Rohi
Published: August 2023

Background: Hemophagocytic Lymphohistiocytosis (HLH) presents a challenging disorder characterized by complex manifestations resulting from dysregulated immune responses. This study aims to enhance our understanding of the clinical and hematological spectrum of HLH, focusing on adult patients.
Methods: A retrospective-prospective observational study was conducted involving 64 adult HLH patients meeting HLH-2004 criteria. Comprehensive hematopathological assessments were performed, encompassing clinical parameters, hematological markers, and mortality rates. Data analysis utilized SPSS Version 20.0 for descriptive statistics.
Results: The most frequent clinical manifestations were fever (100%), splenomegaly (87.5%), bicytopenia (73.4%), hypertriglyceridemia (60.9%), hyperferritenemia (48.4%), hypofibrinogenemia (32.8%), and pancytopenia (26.6%). We observed that leucopenia was present in majority of patients (62.5%), and leukocytosis was present in 17.2% patients. About 65.6% had mild to moderate thrombocytopenia, followed by 14.1% patients with severe thrombocytopenia, 14.1% had normal platelet count and 6.3% had thrombocytosis.
Conclusion: The study revealed a diverse clinical spectrum within adult HLH patients, including universal fever, varied hematological irregularities, and mortality rates of 7.8%. These findings emphasize the complexity of HLH and the importance of early diagnosis and tailored interventions for improved outcomes. This study contributes valuable insights to the understanding of HLH's intricate clinical and hematological aspects, informing more informed diagnostic and therapeutic strategies for this complex disorder.

Kota Solo saat ini perkembangannya sangat pesat dimana banyak bermunculan perhotelan, pertokoan serta perkantoran. Penghasilan masyarakat kota Solo setiap tahun  meningkat sehingga pemakaian energi listrik  juga semakin bertambah banyak. Letak pusat pembangkit tenaga listrik kepada konsumen jaraknya sangat jauh. Untuk menyalurkan energi listrik dari pusat pembangkit tenaga listrik ke konsumen terlebih dahulu menaikan tegangan dengan trafo step up kemudian ditransnisikan ke pusat-pusat beban listrik. Digardu induk tegangan diturunkan menggunkan trafo step down.  Setelah tegangan energi listrik diturunkan pada gardu induk kemudian didistribusikan melalui trafo distribusi agar sampai kepada konsumen listrik. Selama penyaluran listrik dari pusat pembangkit tenaga listrik ke pelanggan listrik akan terjadi pengurangan muatan listrik. Faktor terjadi berkurangnya kapasitas tenaga listrik disebabkan ada sejumlah unsur seperti jarak penyaluran dari pusat pembangkit ke konsumen sangat jauh, ketaksimetrisan muatan listrik menyebabkan penghantar menghasilkan temperatur tinggi.
Tujuan dari penelitian ini memanisfestasikan turun daya listrik di kota Solo dibawah 10 % supaya energi listrik dapat dinikmati oleh warga kota Solo. Model yang digunakan dalam penelitian ini berupa  model perhitungan rugi daya dan hasil pada jaringan distribusi dengan memakai struktur kurva daya dan dikaitkan dengan kurva beban pada masing-masing stasiun distribusi. Rugi daya saluran teganggan medium diperhitungkan   sesuai dengan jumlah arus beban yang mengalir pada kawat penghantar. Pada saat yang sama, rugi daya trafo dihitung berdasarkan kondisi beban. Berdasarkan hasil perhitungan untuk beban tegangan medium yang terkecil pada gardu SKA 2114 sebesar 21,701 KVA dan terbesar pada gardu SKA 2104 sebesar 74,36 KVA. Sedangkan hasil perhitungan untuk arus nominal trafo yang terkecil yaitu pada gardu SKA2101, SKA2102, SKA2103, SKA2110, SKA 2111, SKA2112, SKA2113, SKA2114, SKA2115, SKA2116, SKA2117 yaitu sebsar 5,28 Ampere dan untuk yang terbsar pada gardu SKA2107 sebesar 11,56 Amper. Hasil perhitungan prosentase rugi trafo pada saat pembebanan yang terkecil yaitu pada gardu SKA 2104 sebesar 1,17% dan terbesar pada gardu SKA 2114 sebesar 4,56%.

To assess the relative toxicity of a mixed series of 21(linear and branched-chain) alcohols and 9 normal aliphatic amines in terms of the 50% inhibitory growth concentration (IGC50) of Tetrahymena Pyriformis, a Quantitative Modeling study know as a Structure-Activity/property/Toxicity Relationship (QSAR/QSPR/QSTR) was conducted (20 training,10 tests). The used least squares LS method has been using MINITAB 16 Software and nom-parametric estimation (least absolute deviation LAD) (robust regression method) has been using Calculation Programs by MATLAB Software. The applied simple linear regression approach is based on theoretical H4p (GETAWAY descriptor) molecular descriptor from DRAGON software The performance of regression is better if the distribution of errors has normal, in this case we use the least squares LS method for statistical analysis. When the data does not have a natural assumption, we move to another method of analysis that is more robust and more frequent for the presence of the points of articulation, which is the least absolut deviation method (LAD). The findings of statistical analysis for the chosen model (QSAR) using simple linear Regression using the least Squares Method were R^2=97.39% ,Q^2=96.69% ,Q_bOOT^2=96.24%,Q_EXT^2=93.91% ,R_adj^2=97.24%, S=0.248 Anderson Darling (AD) test =1.57 >0.752 , symmetry coefficient (ou skeweness) (sk= 2.14>0 ) , flatness coefficient (Kurtosis) (ku=5.75>3) and Jarque and Bera Test (JB= 42.84>5.9942. the results did not follow the normal law (unnormal). The coefficient of determination and the value of standard deviation are both highly sensitive to the presence of aberrant compounds(abnormales), as the R^2value moved from 87, 96 % to 94.18 %, which increased by a value of 6.22% and the value of standard deviation (S) moved from 0.399 to 0.303, it increased by a value of 25 % after removing aberrant compound (abnormalie) are interpreted as better adjustment and they are positively. After removing the aberrant compound, we did not see any change in the lines coefficients, indicatting that the function’s graph is stable, demonstrating the LAD method and increased power, which are unaffected by the presence of aberrant compounds Consequently, which means that the model of one descriptor selected is good and statistically strong, Three influential compounds detected ((one compound of training, two compounds of Test) and important the model and absence of studied sample aberrants compounds.

Generative models in computer vision and biometrics
Authors: Štruc Vitomir
Published: August 2023

With the developments in the field of generative modeling and with the appearance of powerful model architectures, such as Generative Adversarial Networks (GAN), a wide range of new techniques and inventive algorithms has emerged recently to solve diverse computer vision problems, including many problems in the area of biometrics.

In this talk, I will first provide a short overview of recent advances in generative modeling and describe some of our research efforts that focus explicitly on generative models.

Next, I will present examples of our recent work utilizing generative models and talk about: (i) face image editing with our GAN inversion based MaskFaceGAN technique that allows for photo realistic image manipulation and explicitly addresses the problem of attribute entanglement seen with many latent-space based editing solutions, (ii) computer vision for fashion and virtual try-on with our context-driven C-VTON model and (ii) bimodal ocular image generation (and annotation) with our Dual-Branch StlyGAN2 (DB-StyleGAN) model.

Finally, I will elaborate on some of the existing challenges with generative models and highlight future research directions.
Generative Volumetric Video for Interactive Virtual Humans
Authors: Eisert Peter
Published: August 2023

Photo-realistic modelling and rendering of humans is extremely important for virtual reality (VR) environments, as the human body and face are highly complex and exhibit large shape variability but also, especially, as humans are extremely sensitive to looking at humans. Further, in VR environments, interactivity plays an important role. While purely computer graphics modeling can achieve highly realistic human models, achieving real photo-realism with these models is computationally extremely expensive. Hence, more and more hybrid methods have been proposed in recent years. In this talk, the creation of high-quality animatable volumetric video content of human performances is addressed. Recent progress in learning human motion and appearance, neural rendering, and implicit function rendering (e.g. NeRF) enable the creation of realistic representation of virtual humans.

We combine these approaches with classical models in order to obtain full control for body and face animation. Different concepts ranging from animatable volumetric video to pure data driven representation will be presented that target the realistic animation of virtual humans for different applications.
What’s up with Image & Video Forensics?
Authors: Pérez-González Fernando
Published: August 2023

This talk will be a journey through more than 20 years of research in video image forensics, which was born to respond to challenges of the digital era such as integrity and authenticity verification and source attribution. We will examine some of the characteristics that have made it possible, from the use of intrinsic features in the acquisition devices, such as lens aberration or demosaicing filters to the traces left by the postprocessing, in order to grasp how methods have evolved from making use of relatively simple statistical models to much more complex ones that rely on deep learning.

In particular, we will see this evolution with **two classic problems**:

1. The identification of the device that captured a given image, to which the use of the PRNU (Photo Response Non-Uniformity) opened the door and which has currently expanded the type of fingerprints that can be extracted and used successfully

2. The detection and localization of image manipulations through the traces of double compression, which now benefits from the ability of DNNs to learn models with richer dependencies.

But not only forensic techniques have evolved: first, the popularization of computational photography with lens distortion corrections, high-dynamic range algorithms, video stabilization or AI-based filters, etc.; second, the ever more prevalent use of social networks for image and video exchange often with proprietary transcoding; and third, the advent of Deep Fakes, imply that many of the techniques developed in the past must be continuously revised to respond to all these novel and demanding challenges.

Last, we will briefly discuss the ethical and legal implications of image and video forensics, especially when it comes to the use of AI.
Biases, Discrimination, and Fairness in Biometrics and Beyond
Authors: Fierrez Julian
Published: August 2023

In the last few years, we are witnessing a growing interest in the Artificial Intelligence research community in studying bias effects when machine learning methods are applied on large amounts of data.

These bias effects can stem from the data itself or from the learning process, which nowadays is clearly dominated by deep learning methods that most of the time are quite opaque. When those learning processes are related to AI applications dealing with personal information, or whose application affects people’s lives, then biases can result in unfair AI-based automated decision-making processes, very harmful in terms of undesired discrimination among population groups.

This keynote will discuss the current state of the topic with special emphasis in AI applications involving face biometrics. Recent methods and approaches to reduce undesired discrimination towards fair biometrics will be also discussed.
