Some Physical and Chemical Conditions Affecting the Distribution of Aquatic Beetles: Lake of Sidi Boughaba as a Case Study (Kénitra, Morocco)

Wetlands present an important diversity of life and are very productive. Many biotic and abiotic factors intervene in their functioning. Thus, understanding this functioning requires, among other characteristics, physicochemical characterization of their waters and the determination of the specific structure of the stand that inhabits those environments. In this work, the authors were interested in the characterization of the waters of Lake Sidi Boughaba, wetland, and biological reserve registered with the RAMSAR convention. This lake is made up of three parts of unequal volume and duration of flooding. The results showed that the studied living environment is very heterogeneous physicochemical and that from one biotope to another the values of the majority of the physicochemical parameters can vary from single, to double, to three times, and even more. Only the pH, oxygen, and ammonium content are relatively stable. In addition, the results showed that the aquatic beetle population of the prospected environment consists of 34 species and subspecies, grouped into 9 systematic families and that the Dytiscidae family and the Hydrophilidae family are the most represented. Likewise, the biotypological analysis of the population of beetles collected showed the distribution of the 34 inventoried species that are divided into four groups and that, among the 16 physicochemical parameters studied 10 intervene the determination of the specific structure of each of the groups of 'identified species.
Positive and negative psychosis risk symptoms among adolescents in Ghana

ABSTRACT Psychotic-like experiences (PLEs) have attracted increased scholarly attention; however, there are limited empirical studies in Africa where environmental risk factors for psychosis such as maltreatment are highly prevalent. The study investigated the prevalence and characteristics of PLEs, as well as the association between PLEs and behavioural maladies among adolescents in Ghana. Data were collected from 553 adolescents (girls = 322, 58.1%) using a cross-sectional survey design. The prevalence of the positive PLEs ranges from 3.8% to 41.2, whereas, for negative PLE, the prevalence ranges from 4.9% to 13% . The PLEs dimensions were significantly associated with depressive and anxiety symptoms, as well as suicidal tendency. Cluster analysis identified three groups of participants: normative, low risk and high risk for psychosis. The psychosis risk groups significantly reported more PLEs and behavioural maladies, compared with the normative group. This preliminary study suggests that psychosis risk symptoms are prevalent in adolescents in Ghana.
Treatment of rectal cancer in the older population

The majority of rectal cancer patients are elderly. Biological age, not chronological age alone, is the main risk factor of postoperative morbidity in this group. Therefore, based on the Comprehensive Geriatric Assessment, we can differentiate three groups of patients: fit, pre-frail and frail. In the fit group, a standard multimodal oncologic treatment can be offered. In the pre-frail group, prerehabilitation should be recommended to improved resilience to surgical stress. In frail patients, a tailored approach should be discussed in a geriatric multidisciplinary team meeting. At present, a whole range of multimodal tailored approaches can be offered to rectal cancer patients. In this group, of much more importance is postoperative functional recovery, including both organ-specific outcomes and the ability to regain independence than currently used outcome indicators. Therefore, as important as cancer staging and tumour biology, it is crucial to understand the health status of an older patient with rectal cancer.
CEO Turnovers: Transparency of Announcements and the Outperformance Puzzle

This study investigates market reactions to announcements of CEO turnover and finds that forced turnovers are not accompanied by positive returns, which contradicts the broad view that firing a CEO sends a positive signal to the market. This contradiction is further explored by focusing on the nature of not only turnover but also a firm’s past performance. This study finds that the market seems to incorporate both types of information in reacting to CEO turnover announcements. Firing an underperforming CEO is viewed as a positive signal, whereas firing an outperforming CEO is viewed as a negative signal. Rather than taking early action against CEOs for a deterioration in their performance, firms appear to be firing outperforming CEOs owing to their apparent nonperformance-related reasons. This study also explores reasons behind the decision to fire a CEO from different news databases and finds that giving no clear reasons for a CEO’s departure increases uncertainty in the market, thereby causing a negative market reaction. However, stating performance as the reason for the departure assures investors about the future trajectory of the firm and results in a positive market reaction.
Determinants of zoogeographical boundaries differ between vertebrate groups

Aim: Worldwide distribution patterns of living animals are structured in multiple zoogeographical regions, characterized by faunas with homogeneous composition that are separated by sharp boundaries. These zoogeographical regions can differ depending on the considered animal group, probably because they have distinct characteristics such as dispersal, metabolism, or evolutionary history, and thus divergent responses to major biogeographical drivers, such as tectonic movements, abrupt climate transitions and orographic barriers. Here, we tested if the drivers of biogeographical boundaries are different between
Effect of Adding Watermelon Juice, Vitamin E-Selenium, and Vitamin C into the Drinking Water on Growth Performance, Internal Organs’ weight and Prececal Nutrient Digestibility in Broilers under Heat Stress

This study investigated the effect of adding watermelon juice, vitamin Eselenium and vitamin C to the drinking water on growth performance, internal organs’ weight, and prececal nutrient digestibility in broilers under heat stress. Two hundred and fifty Hubbard F15 day-old broilers were allocated to five treatments with five replicates of 10 broilers per each replicate, based on a completely randomized design. The birds in the control treatment did not receive any supplement in drinking water and reared in thermoneutral temperature. Birds in the other four treatments received watermelon juice at 60% or 30%, vitamin C at 50 mg/L, or vitamin E-Selenium at 1 mL/L of drinking water during the heat stress period. Heat stress applied for 9 hours from day 12 onward. Results indicated birds that received 60% watermelon juice had similar body weight and feed intake compared to control birds. The relative weight of proventriculus, intestine length, and prececal dry matter nutrient digestibility was significantly higher in 60% watermelon juice treatment than other treatments. It is concluded that watermelon juice supplementation at 60% concentration into the drinking water could improve the performance of birds reared under heat stress as a result of restoring water and feed intake and also better prececal dry matter digestibility.
Electrochemical Devices Derived from Pyrolyzed Graphitic Polyacrylonitrile

Author(s): Pollack, Brandon Davidovich Ryan | Advisor(s): Madou, Marc | Abstract: In this work I present a simple route for fabrication of a graphitic carbon and use that toproduce hydrogen peroxide sensors. The graphitic carbon was shown to have superior elec-trocatalytic properties when compared to its more standard fabrication routes. This wasdone by using the technique of electrospinning to create a nanofibrous mat out of the poly-mer polyacrylonitrile (PAN). The electrospinning, along with additions of carbon nanotubes(CNT) subjected the nanofibers to a force capable of unwinding the molecular chains of PAN. This unwinding was then maintained by subjecting the nanofiber mats to mechanica lstresses, prior to and during a stabilization process which helps the PAN cross-link. Finally,these mechanically treated mats were then pyrolyzed into carbon structures.Mats were fabricated to have a graphitic nature despite being pyrolyzed at relatively low temperatures (1000°C). The mats were characterized Raman Spectroscopy, Transmission Electron Microscopy (TEM), and X-ray Photoelectron Spectroscopy (XPS). This showed in-creased graphitization compared to non-stressed mats and demonstrated interesting elechtro-chemical behavior.n terms of electrochemical properties, the mechanical treated carbons showed an increase inthe heterogeneous electron transfer rate. This presented the opportunity to test the carbonmats as an electrochemical sensor. Hydrogen peroxide sensing was performed where it proved to be on par with other more expensive carbon based materials.
A nutrient‐rich traditional insect for improving food security and reducing biodiversity loss in Madagascar and sub‐Saharan Africa

Forests, and the vertebrate species within them, are irreplaceable sources of food and nutrition for millions of people living in areas of high biodiversity. Unfortunately, many of these forests are being cleared for agriculture, and many animals are threatened with extinction from unsustainable hunting. Forest clearing and the hunting of threatened species are untenable solutions to long‐term food insecurity and adequate nutrition, jeopardizing these species' survival, the healthy functioning of ecosystems, and the cultural identities of local people. Working with communities to develop culturally appropriate ways for people to obtain sustainable and legal sources of food from forests outside of protected areas is a key component of improving both conservation and food security. We tested the feasibility, suitability, and viability of farming an abundant and traditionally eaten forest insect, Zanna tenebrosa (locally known as sakondry), in rural communities whose food security relies heavily on the hunting of threatened vertebrates. We found that the insect is high in macro‐ and micronutrients, and can be cheaply, easily, and sustainably cultivated to sustainably diversify forest food systems without increasing habitat loss. Given the range of Z. tenebrosa, which covers a broad swath of central Africa, increasing production of this native insect may support multipronged agroecological approaches to promoting food security, adequate nutrition, and wildlife conservation.
Klasifikasi Genre Manga Menggunakan Convolutional Neural Network

Peneliti melakukan percobaan tentang klasifikasi genre manga berdasarkan input berupa gambar hitam putih dan cover manga. Menentukan genre manga merupakan hal yang cukup menantang karena genre adalah fitur yang tidak terlihat secara fisik dalam manga, sehingga model deteksi gambar yang tersedia tidak dapat disesuaikan dengan mudah ke dalam konteks ini. Selain itu, multi-label classification lebih menantang dari binary classification ataupun multi-class classification mengingat satu input dapat ditetapkan ke beberapa kelas sekaligus. Setelah berhasil melakukan prediksi genre, maka selanjutnya yang perlu dilakukan adalah menganalisa data yang ada sehingga menemukan faktor yang bisa mempengaruhi hasil akhir yang ditemukan. Convolutional Neural Network merupakan metode yang sering digunakan untuk melakukan klasifikasi gambar karena mampu mendeteksi fitur utama gambar, kombinasi lapisan arsitekturnya mampu menghasilkan prediksi yang kompleks dan relevan. Lapisan arsitektur neural network meliputi convolutional layer, pooling layer, dan fully connected layer. Setiap layer memiliki parameter yang bisa diubah sesuai kebutuhan penelitian. Perubahan parameter ini memungkinkan peneliti untuk memperoleh hasil yang berbeda. Percobaan dilakukan melalui dua tahapan. Tahap pertama berisi 15 percobaan dengan struktur model convolutional neural network yang sama. Tahap kedua berisi 24 percobaan dengan mengubah struktur model convolutional neural networknya. Total keseluruhan percobaan yang dilakukan adalah 39 percobaan. Hasil terbaik yang diperoleh adalah percobaan ke-38 dengan akurasi 46.3 persen dan jumlah F1 yang aktif adalah 25 genre. Selain itu, peneliti telah menganalisa beberapa faktor yang mempengaruhi hasil penelitian yang telah diperoleh dengan harapan bisa berguna untuk peneliti lain yang ingin melakukan penelitian sejenis.
Cognitive Inertia: How Loops Among Attention, Representation, and Decision Making Distort Reality

The decisions we make in our everyday lives often require us to navigate through a barrage of information, so that we can base our decisions only on information that is relevant to our goals. Selectively attending only to goal-relevant dimensions of information can help us efficiently navigate this barrage of information, but can also lead us into ``traps" where we fail to learn which information is most relevant, or fail to notice information that becomes relevant later in time. Here, we investigate the dynamic interactions between attention, learning, and memory that unfold as learners seek to identify dimensions of information that will help them make consistently accurate decisions. Using a multi-pronged approach, we identify the cyclical links between decision making, attention, and representation that best explain human category learning. We then show how the structure of these relationships paradoxically causes both accelerated learning and leads learners into different types of learning traps.
Vom Glück der Berufung: "Glück" als Topos in Berufsbiographien des wissenschaftlichen Nachwuchses

Zusammenfassung (Nachwuchs-)Wissenschaftlerinnen und Wissenschaftler verweisen im Zusammenhang mit ihrer beruflichen Laufbahn haufig auf Gluck. Diese empirische Beobachtung aus einem Forschungsprojekt greift der Beitrag auf und fragt nach dem Warum. Er zeigt, ausgehend von der empirischen Verwendung des Begriffs Gluck, wie die im Projekt Befragten die Entwicklung ihrer Laufbahn als biographische Folge eines Einflusses durch die Universitat und die Professorenschaft einordnen. Die Analyse von Facetten des kommunikativen Einsatzes von Gluck als biographischem Topos legt offen, dass es – entgegen der etablierten Interpretation von Webers „hasard“ als Zufall – unzureichend ist, „Gluck“ in seinen verschiedenen kommunikativen Verwendungen in biographischen Selbstentwurfen von (Nachwuchs-)Wissenschaftlerinnen und Wissenschaftlern ausschlieslich mit „Zufall“ gleichzusetzen. Vielmehr muss die Nutzung dieses Topos als Ausdruck der Unberechenbarkeit und Personenabhangigkeit gesehen werden, die fur die Universitat als Expertenorganisation im Spannungsfeld zwischen konservativem, meritokratischem Prinzip einerseits und unternehmerischem Wandel andererseits konstitutiv ist. ----- Bibliographie: Richter, Caroline: Vom Gluck der Berufung. „Gluck“ als Topos in Berufsbiographien des wissenschaftlichen Nachwuchses, BIOS, 1-2016, S. 47-66. https://doi.org/10.3224/bios.v29i1. 04
A level set-based approach for modeling cellular rearrangements in tissue morphogenesis

Mathematical models and numerical simulations can provide an essential insight into the mechanisms through which local cell-cell interactions affect tissue-level cell morphology. Among such morphological phenomena, cellular patterns observed in developing sensory epithelia have gained keen attention of researchers in recent years, because they are thought to be of utmost importance for accurate sensory functions. However, most of current computational approaches to cellular rearrangements lack solid mathematical background and involve experimentally unreachable parameters, whereby only weak and ambiguous conclusions can be made based on simulation results. Here we present a simple mathematical model for tissue morphogenesis together with a level set-based numerical scheme for its solution as a tool to rigorously investigate evolving cellular patterns. This combined framework of a model and a numerical method features minimum possible number of physical parameters and guarantees reliability of simulation results, including correct handling of topology changes, such as cell intercalations. In this framework, we adopt the viewpoint of free energy minimization principle, and take cellular rearrangement as a gradient flow of a weighted surface energy associated with cell membrane, where the weights are related to physical parameters of the cells, for example, cell-cell adhesion and cell contractility. We present the applicability of this model to a wide range of tissue morphological phenomena, such as cell sorting, engulfment or internalization. In particular, we stress that this method is the first one to be successful in computationally reproducing the experimentally observed development of cellular mosaic patterns in sensory epithelia. Thanks to its simplicity and reliability, the model is able to capture the essence of biological phenomena, and may give a strong helping hand in deciphering unsolved questions of morphology.
Iterative Methods for the Computation of the Perron Vector of Adjacency Matrices

The power method is commonly applied to compute the Perron vector of large adjacency matrices. Blondel et al. [SIAM Rev. 46, 2004] investigated its performance when the adjacency matrix has multiple eigenvalues of the same magnitude. It is well known that the Lanczos method typically requires fewer iterations than the power method to determine eigenvectors with the desired accuracy. However, the Lanczos method demands more computer storage, which may make it impractical to apply to very large problems. The present paper adapts the analysis by Blondel et al. to the Lanczos and restarted Lanczos methods. The restarted methods are found to yield fast convergence and to require less computer storage than the Lanczos method. Computed examples illustrate the theory presented. Applications of the Arnoldi method are also discussed.
Unified Analysis Specific to the Medical Field in the Interpretation of Medical Images through the Use of Deep Learning

Deep learning (DL) has seen an exponential development in recent years, with major impact in many medical fields, especially in the field of medical image. The purpose of the work converges in determining the importance of each component, describing the specificity and correlations of these elements involved in achieving the precision of interpretation of medical images using DL. The major contribution of this work is primarily to the updated characterisation of the characteristics of the constituent elements of the deep learning process, scientific data, methods of knowledge incorporation, DL models according to the objectives for which they were designed and the presentation of medical applications in accordance with these tasks. Secondly, it describes the specific correlations between the quality, type and volume of data, the deep learning patterns used in the interpretation of diagnostic medical images and their applications in medicine. Finally presents problems and directions of future research. Data quality and volume, annotations and labels, identification and automatic extraction of specific medical terms can help deep learning models perform image analysis tasks. Moreover, the development of models capable of extracting unattended features and easily incorporated into the architecture of DL networks and the development of techniques to search for a certain network architecture according to the objectives set lead to performance in the interpretation of medical images.
RNA binding protein CUGBP1 mediates the liver metastasis of colorectal cancer by regulating the ErbB signal pathway

Background The CUGBP1 (CELF1) is differentially expressed in liver metastasis and no liver metastasis colorectal cancers (CRC) tissues and the function of CUGBP1 in CRC is still unclear. Methods Five cases of colorectal adenocarcinoma and 6 cases of liver metastatic CRC lesions were collected and subjected to cDNA microarray and bioinformatical analyses. The quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to confirm the result. Cell function assays were used to study the function of CUGBP1, and the western blot was used to discover the change of the downstream molecules. Results CUGBP1 was significantly elevated in liver metastatic CRC lesions. Besides, the CUGBP1 can promote proliferation, colony formation, invasion, metastasis abilities as well as increase the apoptosis rates of CRC cells. ERBB2 was positively related to the CUGBP1. Western blot results found that silence of CUGBP1 decreased the protein level of p-AKT and p-ERK without influence the expression level of total protein of AKT and ERK. Conclusions CUGBP1 can promote liver metastasis of CRC by promoting the phosphorylation of AKT and ERK through the ErbB signaling pathway. CUGBP1 is a potential biomarker for early detection of CRC and maybe a novel therapeutic target of CRC treatment, especially in liver metastasis.

Compact dual‐band bandpass filter with high‐passband isolation using coupled lines and open stub

This article presents the design and analysis of a compact dual‐band bandpass filter employing coupled lines and open circuit stub. The filter frequency response contains two passbands with good isolation between them and five transmission zeros in the stopband. The analytical design equations for transmission zero frequencies are obtained based on lossless transmission line theory and the even and odd mode analysis method. A dual‐band bandpass filter operating at GSM (0.9 GHz) and Wi‐Fi (2.4 GHz) frequencies is designed, fabricated, and tested. The proposed design method is verified by the excellent agreement between the simulated and measured results.
Diseño y Validación de la Escala de Sensibilidad al Rechazo Amoroso (SRA)

Rejection is a distressing experience to which each person reacts differently, as some are more sensitive to it than others. Sensitivity generates anxiety and easy perception of a rejection that could be real or imaginary and to which one reacts in an extreme way. The aim of the study was to design and validate the Scale of Sensitivity to Romantic Rejection (SRR), through two phases; First, we focused on understanding the meaning of sensitivity to romantic rejection. Second, we performed an exploratory factor analysis of the scale. The results show three dimensions: affective reactions, anticipation and cognitive reactions. It is suggested that these factors are determined by culture, the findings are argued, and their relevance is discussed.
