Short-Term Electrical Load Forecasting in Power Systems Using Deep Learning Techniques
Authors: PAMUK Nihat
Published: October 2023

The use of big data in deep neural networks has recently surpassed traditional machine learning techniques in many application areas. The main reasons for the use of deep neural networks are the increase in computational power made possible by graphics processing units and tensor processing units, and the new algorithms created by recurrent neural networks and CNNs. In addition to traditional machine learning methods, deep neural networks have applications in anticipating electricity load. Using a real dataset for one-step forecasting, this article compares three deep learning algorithms for short-term power load forecasting: LSTM, GRUs, and CNN. The statistics come from the Turkish city of Zonguldak and include hourly electricity usage loads and temperatures over a period of three years, commencing in 2019 and ending in 2021. The mean absolute percentage error is used to compare the performances of the techniques. Forecasts are made for twelve representative months from each season. The main reason for the significant deviations in the forecasts for January, May, September, and December is the presence of religious and national holidays in these months. This was solved by adding the information obtained from religious and national holidays to the modeling. This is not to say that CNNs are not good at capturing long-term dependencies and modeling sequential data. In all experiments, LSTM, GRUs and encoder-decoder LSTM outperformed simple CNN designs. In the future, these new architectural methods can be applied to long- or short-term electric charge predictions and their results can be compared to LSTM, GRUs and their variations.
Common Solutions to Stein Inequalities

Published: October 2023

In this paper for linear discrete time switched systems, the problem of existence of a common solution to Stein inequalities is considered. A sufficient condition for robust Schur stability of a matrix polyope by using Schur complement lemma and a necessary and sufficient condition for the existence of a common solution of Stein equation are given. As in the case of continuous time systems, the problem of existence of a common solution is reduced to a convex optimization one. An efficient solution algorithm which requires solving a linear minimax problem at each step is suggested. The algorithm is supported with a number of examples from the literature and observed that the method desired results fastly.

Bu bildiride, sivil araç zırhlaması üzerine yapılan araştırmalar ve bu alanda kullanılmak üzere tasarlanan seramik kompozit bir zırhın balistik test sonuçları sunulmuştur. Günümüzün farklı mühimmat tehdit seviyelerine karşı askeri araçlarda olduğu gibi sivil araçlarda da zırhlama çok önemli bir konu haline gelmiştir. Ayrıca ağırlığın çok önemli bir tasarım kriteri olması nedeniyle hafif zırh sistemlerine olan talep de artmaktadır. Ağırlık, aracın yakıt tüketimini, motor gücünü ve ilgili diğer sistem gereksinimlerini artırır ve manevra kabiliyetini azaltır. Çalışmada sunulan bağımsız zırh, sivil araçlarda kullanılmak üzere geliştirilmiş ve zırh panelinin ağırlık kazancı, Ultra Yüksek Sertlikli (UHH) zırh çelikleri (Armox 600T ve Armox Advance) ile karşılaştırılmıştır. Geliştirilen zırh, darbe yüzünde alümina (Al2O3) seramik karolardan ve son katmanda Ultra Yüksek Moleküler Ağırlıklı Polietilen (UHWMPE) kompozit destek plakasından oluşmaktadır ve 7.62 mm x 51 M61 AP mermiye karşı test edilmiştir. Hafif zırh panelinin beş atıştan sonra yapısal bütünlüğünü koruduğu gözlemlenmiştir. Geliştirilen zırh panelinin sivil zırhlı araçlar için 7.62 mm zırh delici mühimmatlara karşı hafif ve uygun maliyetli çözüm sağladığı değerlendirilmektedir.

Published: October 2023

Çeşitli sistemlerin gerçek zamanlı izlenmesini ve yönetimini sunma kapasitesi nedeniyle, Kablosuz Algılayıcı Ağ (Wireless Sensor Networks-WSN) ve Nesnelerin İnterneti (Internet of Things-IoT) teknolojileri, askeri ve güvenlik alanlarında giderek daha popüler hale gelmektedir. Akıllı gözetim sistemleri, video analitiği, akıllı ev uygulamaları ve savunma ve güvenlik sistemleri, gözetim uygulamaları için IoT kullanımındaki güncel gelişmelerden bazılarıdır. Bununla birlikte, IoT alanında birtakım zorluklar vardır ve bu zorluklar kabaca iki sınıfa ayrılabilir: kaynak sınırlamaları birinci sınıf, gizlilik ve güvenlik konuları ise ikinci sınıftır. Kaynak açısından zengin ağ geçidi düğümleri veya ağ ömrünü artırmaya çalışan etkili algoritmalar gibi farklı stratejiler oluşturulmuş ve kaynak sınırlamalarının üstesinden gelmek için temel araştırma çabaları haline gelmiştir. Buna ilave olarak, IoT alanında gizlilik ve güvenlik endişelerini gidermeye yönelik çok sayıda öneri literatürde yer almaktadır. Ancak, bunların çoğu WSN ve IoT alanının kendine özgü özellikleri nedeniyle beklentilerin altında kalmıştır. Alanın bu benzeri görülmemiş zorluklarını göz önünde bulunduran bu çalışma, öncelikle savunma ve güvenlik alanında WSN ve IoT kullanımına ilişkin literatürü kapsamlı bir şekilde gözden geçirmekte ve ardından sınır güvenliği uygulamaları için Blokzincir tabanlı IoT kullanarak etkili ve güvenli bir çözüm önermektedir. Öneri, konsept doğrulama ve bağımlılık yönlerinden deneysel testlere tabi tutulmuş ve testlerden elde edilen bulgular önerilen yaklaşımın uygunluğunu ve fizibilitesini doğrulamaktadır.

Published: October 2023

The data of cobalt and copper effect on the development of Kamchatka brown alga Fucus distichus subsp. evanescens is presented in the paper. The observations were carried out under laboratory conditions with temperature of 10°C, natural light and a photoperiod from July, 6 to August, 6. The cultivation media contained metals at nominal concentrations of 5, 10, 20, and 50 µg/l. It was found that Co addition to the medium mostly stimulated germlings growth. The average growth rate varied from 15.6 to 23.5 µm/day during entire experiment period but did not exceed 16.1 µm/day in the control group. On the contrary, a significant decrease of growth in groups grown in excessive copper media was revealed. By the end of the experiment the rate of germlings growth in media with copper of 10, 20, and 50 µg/l did not exceed 6 µm/day; in the media with minimum metal content was 11.2 µm/day. Also the abnormal formation of germlings rhizoids, the presence of extra- and intracellular copper deposits and underdevelopment of hyaline hairs were observed in all cultures with excessive copper content. The obtained results can be used to predict the responses of Fucus littoral communities to cobalt and copper environment pollution.
CORRELATION BETWEEN THE NUMBER OF SOCKEYE SALMON (ONCORHYNCHUS NERKA) PRODUCERS AND WINTERING STELLER’S SEA EAGLES (HALIAEETUS PELAGICUS) ON LAKE KURILSKOYE (SOUTHERN KAMCHATKA)

Published: October 2023

A phenomenal winter cluster of three large bird species of prey such as Golden eagle (Aquila chrysaetos), White-tailed eagle (Haliaeetus albicilla) and Steller’s sea eagle (H. pelagicus) is recorded on Lake Kurilskoye more than 40 years annually. The Steller’s sea eagle is a dominant species. The long-term dynamics of Steller’s sea eagle number on Lake Kurilskoye demonstrates obvious connection between the number of birds and sockeye salmon producers (Oncorhynchus nerka). However, no statistical data processing was carried out and the significance of this relationship was unknown. The correlation coefficient between the number of Steller’s sea eagles and sockeye salmon that came to spawn during 1976–2008 was 0.673. It indicates the significant relationship between the number of fish and large bird species of prey wintering on the lake. At the same time, it was found that the correlation indicators changed functionally in different periods of time.

WETTABILITY STUDIES ON FEMTOSECOND-¬LASER-TEXTURED N-TYPE SILICON SURFACES
Authors: Vipparla Srikanth , G.L. Samuel , Wei Dongbin
Published: October 2023

This present study examines the wetting behavior of N-type silicon surfaces that have been textured using a femtosecond laser. By employing three different patterns, i.e., square pillars, micro dimples, and circumferential grooves, and manipulating key femtosecond laser parameters such as laser power (ranging from 8 W to 12 W) and repetitions (ranging from 40 to 60), the wettability properties of the silicon surfaces are modified. The wettability properties of the surface were evaluated by measuring the contact angle by the sessile-drop method using distilled deionized water as a testing liquid. The textured surfaces displayed various wettability characteristics, varying from hydrophilic to hydrophobic. The hydrophobic behavior was observed on surfaces with a peak laser power of 12 W, 60 repetitions, and the lowest pitch of 160 µm. For the square pillar and micro-dimple textures, contact angles of 146° and 120°, respectively, were measured. Conversely, the circumferential grooves exhibited hydrophilic behavior with a contact angle of 20°. These results were achieved at laser powers of 10 W and 8 W, higher pitch values, and increased repetitions. The contact angle decreased with an increase in pitch and a decrease in repetitions and laser power. Based on the experimental findings, it can be concluded that the wettability of silicon surfaces can be controlled for specific applications using a single-step laser ablation technique. The desired wettability characteristics can be achieved by carefully adjusting the key femtosecond-laser parameters and geometrical features.
Jornalistas Locais e Fact-Checking: Um Estudo Exploratório em Portugal e Espanha
Authors: Jerónimo Pedro , Sánchez Esparza Marta
Published: October 2023

A invisibilidade noticiosa a que estão a ser votadas várias cidades em diferentes países faz-nos questionar sobre as consequências para as respetivas comunidades. O desaparecimento de projetos jornalísticos de âmbito local leva a que o vazio deixado possa ser ocupado por outro tipo de realidades, menos comprometidas com o escrutínio dos poderes. A polarização cresce nestes lugares, a participação cívica diminui e isso terá como consequência o empobrecimento da democracia. Porém, estes sintomas podem existir mesmo com cobertura jornalística, quando ela não é feita de forma rigorosa. Neste estudo exploratório, realizaram-se entrevistas em profundidade a jornalistas de 12 meios regionais de Portugal e Espanha, no sentido de analisar perceções e práticas sobre fact-checking (verificação de factos). Os fatores tempo e recursos disponíveis nas redações, quando em número reduzido, são cruciais sobretudo para que se verifique menos. Também registamos o facto de os jornalistas de ambos os países revelarem uma confiança quase cega nas fontes oficiais. Isto gera um déficit no processo de verificação, quando a informação provém dessas fontes. Por outro lado, os políticos locais não só não colaboram, como dificultam o trabalho de verificação dos jornalistas nas redações dos meios locais, com base nos seus próprios interesses.
Influence of algorithmization and interface for the preparation of management decisions
Authors: Gutgarts Rimma
Published: October 2023

In modern conditions, managerial decision-making is carried out using automated systems under the general name “Decision Support Systems” (DSS). When creating them, it is important to consider two key points. The first is the algorithmic component, which reflects the logic of the system as a whole and its individual parts. The second is the application interface through which the user interacts with it. The interface is a graphical interpretation of the algorithms that are implemented within the system. Therefore, it is very important to design and create such a relationship between the algorithm and the interface so that the user is as comfortable as possible using the DSS to solve current tasks (information input, its processing, presentation and analysis for decision making). Thus, there is a directly proportional relationship between the interface and the algorithm. Moreover, despite the fact that there are many studies on these aspects, both theoretical and practical, there are still questions to which one should pay attention to in terms of application. The purpose of this study is to formulate practical recommendations to prevent the entry of incorrect information into the DSS database and to present the results in a form convenient for its analysis. The main tasks of the work are to show by means of examples which errors can contribute to the entry of unreliable information into the database, as well as how best to present information on the monitor screen in accordance with the psychophysiological characteristics of a person in order to reduce the time for its analysis and decision-making.

Authors: Magaña-Montiel Nallely , F Muriel-Millán Luis , Pardo-López Liliana
Published: October 2023

In microbial biodegradation assays, the detection of bacterial growth in water-based plastic dispersions can be difficult to measure using traditional methods because of the turbidity of culture media and the formation of flocculi. Here, we present a protocol for the detection of bacterial growth in Impranil®DLN, a polyester polyurethane (PU) water-based dispersion. By measuring bacterial metabolic activity, as an indicator of cell viability with the water-soluble 2, 3-bis [2-methyloxy-4-nitro-5-sulfophenyl]-2H-tetrazolium-5-carboxanilide (XTT) salt. Viable growing cells, i.e., those cells that can utilize PU as a carbon source, will reduce the yellow-colored XTT to a water-soluble orange formazan by the action of dehydrogenase enzymes of the respiratory chain. For the standardization of the protocol, we used Pseudomonas putida KT2440 and Escherichia coli BL21 strains as positive and negative controls, respectively. We determined the metabolic activity of the strains grown with citrate or both citrate and impranil as carbon sources. P. putida KT2440 showed higher XTT-detected metabolic activity in the presence of PU than when it was grown only with citrate, indicating that the strain also used PU as a carbon source. In contrast, the negative control did not show differences in metabolic activity between the growth conditions. Our protocol can be adapted to different bacterial strains and culture media.
UPitt TriState SenNet TMC H&E staining v1
Authors: Bueno Marta
Published: October 2023

Hematoxylin and Eosin stains are the preferred method for histopathologic assessment of tissue sections. Hematoxylin is used to illustrate nuclear detail in cells. Depth of coloration is not only related to the amount of DNA in the nuclei but also to the length of time the sample spends in hematoxylin. Eosin is the most commonly used counterstain that distinguishes between the cytoplasm and nuclei of cells. It is typically pink, with different shades of pink for different types of connective tissue fibers. (Note: Bluing reagents, such as Scott's Tap Water, are used to change the hematoxylin from red to the traditional blue color we expect. These slightly basic solutions chemically alter the dye to produce this color change.)

Published: October 2023

This procedure allows to inject a small volume of solution (in our case, either a suspension of genetically modified viruses, that will infect neurons and will induce the expression of desired proteins, often genetically-encoded probes; or a suspension of a chemical neuronal marker, “fluorogold”, that will be taken up that neurons with axonal projections in the area of injection) in a specific region of the brain. An anesthetized mouse is placed on the stereotaxic apparatus, where its head is immobilized and positioned so that once the skull is exposed, specific anatomical landmarks (usually, the bone sutures) can be identified and used to calculate the relative position of different brain areas expressed as x/y/z coordinates. small hole can be drilled in correspondence of the desired x/y coordinates and the injection pipette can then be lowered to desired z coordinate, where the solution is slowly released. After suturing the mouse and waiting an appropriate time for recovery and expression of the protein of interest, the mouse can be sacrificed and used for experiments.

Authors: HG Kelley BSc Rupert
Published: October 2023

As the digital age of dentistry continues to flourish, it has never been more important to have protocols to guide dentists through the planning and performance of treatments using the latest technology and software. This is especially true in the field of orthodontics, where the use of technology has revolutionised treatment outcomes. During the first stages of this protocol, extensive records are collected which are then used throughout the treatment. After that, a shift occurs from two dimensions to three dimensions, and movement of the maxillary teeth begins. Then, the mandibular teeth are moved, and the case is completed. The final step is to check the results and ensure that our outcome matches what was planned before the commencement of treatment. This protocol aims to guide orthodontists in the treatment of their patients no matter the type of treatment that is planned, whether orthodontic, restorative or surgical. At any stage of the treatment, the orthodontist can refer back to the protocol to stay on the path towards a successful outcome for the patient.

Let G=(V,E) be a connected graph and c be a proper vertex coloring using t colors. Vertex coloring on the graph G is a function c:V(G)→{1,2,…,t}, such that c(u)≠c(v) if u and v are two vertices that adjacent to each other. If a graph can be colored with t colors, then the smallest number used on the graph G is referred as a chromatic number, denoted by χ(G). While, the number of distinct ways to color the vertices of G with t colors is called as chromatic polynomial, denoted by P_G (t). In this paper, through axiomatic deductive and pattern detection methods, we propose the chromatic polynomials of complete tripartite graph, denoted by K_((l,m,n) ) for l,m ∈{1,2} and l≤m≤n.Keywords: Chromatic Number, Chromatic Polynomial, Complete Tripartite Graph, Vertex Coloring.  AbstrakMisalkan G=(V,E) adalah graf terhubung dan c adalah pewarnaan titik dengan t warna.

Apabila suatu graf dapat diwarnai sejumlah t warna, maka paling sedikit warna yang digunakan pada graf G disebut sebagai bilangan kromatik dan dinotasikan dengan χ(G). Sedangkan, banyaknya cara yang dapat digunakan untuk mewarnai titik pada graf G dengan t warna yang disediakan disebut sebagai polinomial kromatik dan dinotasikan dengan PG(t).

Published: October 2023

This study is about analysis by creating a Nelson-Aalen curve and determining differences in the curve between categories of each risk factor for Type II Diabetes Mellitus. The analysis method used is the Nelson-Aalen method which is used to create a curve by calculating the cumulative hazard value first and then followed by calculating survival odds, and the Weighted Log Rank Test is used to determine the difference in the curve. The data used was the medical record data of inpatients with Type II Diabetes Mellitus at the Sayang Public Hospital of Cianjur Regency. The result obtained is that the Nelson-Aalen curve shows decreased characteristics, namely the longer the patient is treated, the patient's chances of recovery will be smaller. In other words, the patient's chances of returning home in a state of recovery will be even greater. Furthermore, the test results showed that there was no difference in the case of survival in the factors of age, hypertension, current blood sugar levels, and diabetic legs, while gender factors and balanced diet patterns showed a difference in the chance of survival, which means that both factors affect the chances of survival of Type II Diabetes Mellitus patients at the Sayang Public Hospital of Cianjur Regency.Keywords: Diabetes Mellitus, Nelson-Aalen, Survival Analysis, Weighted Log Rank Test. AbstrakPada penelitian ini disajikan analisa ketahanan hidup dengan membuat kurva Nelson-Aalen dan menentukan perbedaan kurva antar kategori dari setiap faktor risiko Diabetes Mellitus Tipe II. Metode analisis yang digunakan adalah metode Nelson-Aalen yang digunakan untuk membuat kurva ketahanan hidup dengan menghitung nilai hazard kumulatif terlebih dahulu lalu dilanjutkan dengan menghitung peluang ketahanan hidup. Weighted Log Rank Test digunakan untuk menentukan perbedaan kurva. Data yang digunakan adalah data rekam medis pasien rawat inap penderita Diabetes Mellitus Tipe II di RSUD Sayang Cianjur. Diperoleh hasil bahwa kurva Nelson-Aalen menunjukkan karakteristik yang menurun, yaitu semakin lama pasien dirawat maka peluang pasien untuk belum mengalami kesembuhan akan semakin kecil. Dengan kata lain, peluang pasien untuk pulang dalam keadaan telah mengalami kesembuhan akan semakin besar. Selanjutnya, hasil pengujian menunjukkan bahwa tidak terdapat perbedaan peluang ketahanan hidup pada faktor usia, hipertensi, kadar gula darah sewaktu, dan kaki diabetik, sedangkan faktor jenis kelamin dan pola diet seimbang menunjukkan adanya perbedaan peluang ketahanan hidup, yang artinya kedua faktor tersebut memengaruhi peluang ketahanan hidup pasien Diabetes Mellitus Tipe II di RSUD Sayang Kabupaten Cianjur.
Des banzos et des djinns
Authors: Vilarino Júnior
Published: October 2023

Dans cet article, nous analysons le rôle de la mémoire ancestrale dans deux romans contemporains de la diaspora noire, Becos da memória (2006), de l’autrice brésilienne Conceição Evaristo, et Le Jour du roi (2010), de l’écrivain marocain Abdellah Taïa. L’analyse porte sur le point de vue des personnages Totó et Hadda dans les ouvrages respectifs. Nous démontrerons que l’énonciation de leurs discours, marquée par la tonalité du banzo, chez Conceição Evaristo, et par la possession des djinns, chez Abdellah Taïa, réinvente la mémoire sociale de la négritude à partir des marges sociales. L’analyse démontre que, dans ces récits-là, la dialectique du colonialisme se révèle indépassable quant à l’épistémicide linguistique et mnémonique subi par les personnages.
De Chamoiseau
Authors: Lemnouer Ghizlane
Published: October 2023

Le but de cette étude est de montrer comment Chamoiseau, le « Guerrier de l’imaginaire » prône une éthique de la Relation visant la reconnaissance de l›Autre qui ne peut qu’être, selon le poète, une transcendance pour soi-même, transcendance sans cesse renouvelée, allant au-delà de l’extériorité de l’être tout en étant intégrée et reconnue par lui. C›est au cœur de cette perspective à bien des égards humanistes que Chamoiseau mène une critique acerbe, que nous proposons d›analyser, des frontières qui ne cessent de s›ériger en répondant à une logique capitaliste et qui participent à la disparition des lucioles, et se soulève par ricochet contre la barbarie néo-libérale, en vue de parvenir à un idéal de paix dans un monde non plus soumis à la mondialisation mais orienté vers son versant positif, la « Mondialité ». En réaction à la crise des migrants, l›« Écrire » de Chamoiseau se veut ainsi comme un hymne au vivre-en-relation où palpite l›incertain, l›à venir et l›imprévisible.
item lexical “lacrar” nas redes sociais
Authors: Ruas Gabrielle Venâncio
Published: October 2023

Neste trabalho, empreende-se um estudo diacrônico do item “lacrar” e respectivos cognatos no português brasileiro. Por influência das novas demandas de comunicação oriundas da internet, notadamente das redes sociais, esse item tem sofrido processos de neologismo relacionados tanto a seu sentido quanto à sua forma. Para viabilizar a pesquisa, utilizaram-se obras lexicográficas que abrangem o período de 1728 a 2023. Também foram analisadas ocorrências do Corpus do Português (2006), bem como dados extraídos da rede social Twitter, à luz da teoria da variação e mudança linguística. Ao se traçar um percurso diacrônico do termo em foco, constatou-se que este, originalmente presente na língua com o sentido de “pegar, fechar applicando lacre; applicar lacre”, segundo Bluteau (1728), tem sofrido um processo de polissemia que se iniciou entre grupos LGBT+ e, recentemente, estendeu-se ao cotidiano de pessoas com orientações conservadoras, as quais passaram a empregá-lo para criticar ou ironizar discursos de apoio a minorias e a causas sociais. Mediante essa investigação, confirmou-se que a mudança linguística do item “lacrar” está intimamente ligada, portanto, a desdobramentos socioculturais e políticos.
Deux images de cultures francophones chez Jean Cocteau

L’œuvre de l’artiste français Jean Cocteau (1889-1963) est vaste et variée, elle propose en différents langages sa perception de la diversité culturelle au monde. Le Brésil s’intéresse aux créations de cet artiste depuis 1912, un intérêt qui porte entre autres sur les rapports de Cocteau aux diverses cultures. Cet article a pour but de présenter une réflexion sur deux images de cultures francophones, soit l’Algérie et le Sénégal, créées par l’artiste en poésie et au cinéma, et sur leur éventuelle réception brésilienne. Les archives de la Biblioteca Nacional disponibles sur Internet ont été consultées, ainsi que des travaux scientifiques menés au Brésil. Cette recherche a révélé un intérêt brésilien inégal pour les pays visités par Cocteau à travers son art.
Binding of C1q to Galectin-3 Binding Protein on Microvesicles Released by Mononuclear Cells from Patients with Systemic Lupus Erythematosus
Authors: Rasmussen Niclas , Jacobsen Søren , Nielsen Claus , Nielsen Christoffer
Published: October 2023

Background: Generation of galectin-3 binding protein (G3BP)-expressing microvesicles can be induced in-vitro by Toll-like receptor 9 ligation in mononuclear cells. Microvesicles co-expressing G3BP and double-stranded DNA are associated with active lupus nephritis. However, whether the microvesicular G3BP mainly deposits from circulation or is endogenously derived is unknown. In this study, we aim to delineate the origin of G3BP on in-vitro generated microvesicles by using serum as a source of native G3BP. Methods: G3BP-expressing microvesicles, generated by stimulation of systemic lupus erythematosus patient-derived mononuclear cells with the Toll-like receptor 9-agonist ODN2395, were incubated with normal human serum, heat-inactivated human serum, recombinant human C1q or human albumin. The expression of G3BP by microvesicles was examined by flow cytometry, and the binding of soluble recombinant human C1q to recombinant human G3BP was investigated by ELISA. Results: Approximately half of the microvesicles released from mononuclear cells expressed G3BP. Surprisingly, the staining was abrogated by incubation of the microvesicles with normal human serum, while incubation with heat-inactivated human serum did not have a similar effect. Reasoning that C1q might be the heat-labile factor blocking access of our G3BP antibody detection system, we incubated microvesicles with recombinant human C1q, which on average inhibited the detectable proportion of G3BP-bearing microvesicles by 87%. Soluble recombinant human C1q bound to immobilized recombinant human G3BP in a dose-dependent manner. Conclusion: Our data suggest that soluble C1q binds to G3BP on Toll-like receptor 9-induced microvesicles released from systemic lupus erythematosus patient-derived mononuclear cells. This interaction may exarcerbate inflammation in systemic lupus erythematosus but may also serve as a general mechanism for the appropriate clearance of these potentially pathogenic factors. Keywords: microvesicles, C1q, complement, clearance, Toll-like receptor 9, peripheral blood mononuclear cells, galectin-3 binding protein, systemic lupus erythematosus
Success in Grateful Client Philanthropy: Insights from Veterinary Faculty at North Carolina State University
Authors: Dunning Dianne , Hedgpeth Mari-Wells , Dorman David
Published: October 2023

The veterinary literature contains few publications or empiric research on the impact of grateful client philanthropy. To improve our understanding of the impact of philanthropy on veterinary medicine, we surveyed the faculty at NC State University College of Veterinary Medicine. This qualitative study involved an anonymous survey of 153 North Carolina State University College of Veterinary Medicine faculty members administered and analyzed through an online survey software program, QualitrixXMTM. 33% (51) of faculty responded to the survey. 73% (37) of the respondents indicated that their personal interactions with clients led to gifts to their research or service and 29% (15) indicated that they have received six or more gifts from their interactions with clients of the hospital. The top three examples of direct beneficial impacts from grateful client giving were research support (13.1%), technological improvements and equipment upgrades (10.5%), and professional development (4.6%). The top three negative impacts of faculty interactions with a grateful client program were the perceived need to address the overwhelming needs of the donor (19%), the faculty’s concerns regarding the owner’s higher expectations of service (7.1%) and time (7.1%). 61.9% of the respondents did not note any negative impacts.

Assessment of Household Environmental Risk Factors for Falls Among Community Dwelling Older Persons in Thiruvananthapuram District of Kerala
Authors: Ravindran Rekha , Kutty V
Published: October 2023

Falls constitute a major public health problem among older persons worldwide. This study attempted to observe and identify the potential environmental hazards within and outside the houses that could have caused fall-related injuries of older persons. The modifications done to the house after the falls were also observed. Households of older persons who were hospitalised at a tertiary care centre in Thiruvananthapuram district of Kerala, India for complaints of fall related injuries (participants of a case-control study) were observed using a guide that was customized and adapted for the setting. The areas around the houses were slippery and had several tripping hazards. Marble, granite and tiled floors were found to be slippery. Door thresholds, door mats with no grip backing and plastic chairs were found to be potential tripping hazards. Steps/stairs were important in causation of falls. The bedrooms were often dark, small and cluttered with furniture. The bathrooms were frequently located outdoors and at a different level from the rest of the house. Lighting was a problem within the house, inside the toilet and bathrooms. Commonest alteration made to prevent falls was introduction of mats inside and outside the house. Changes that were needed for a safe environment for older persons are often challenged by the need to display status markers. Several potential hazards were identified within and around the house. They either precipitated the falls or modified the outcome of falls. Further research is necessary to work out a guideline for constructing safe and friendly houses for older persons.

Published: October 2023

Health, disease, overdiagnosis and defensive medicine are interrelated complex concepts that lack formal definitions and a uniform holistic perspective. Functional definitions of these concepts are context-specific and differ in relation to clinical practice, research, medical science and health insurance. In the context of clinical practice that is the focus of this review, having no clear working definitions of health, disease, overdiagnosis and defensive medicine is essential for distinguishing people who need medical intervention from those who do not, for formulating accurate diagnosis and treatment options, and for improving professional communication between clinicians and between clinicians and their patients. The purpose of this narrative review is to promote the understanding of the concepts of health, disease, overdiagnosis, defensive medicine and their interrelation in the context of clinical practice, with the view of enhancing the quality of healthcare services.
Consideration of host nutritional status as a mitigating factor against current and future pandemics: a review of nutrient studies and experiences with infectious diseases including Covid-19
Authors: Cheng Richard , Passwater Michael , Yang Tievi
Published: October 2023

For over 3 years, the Covid-19 pandemic felt like a world war and has taken close to 7 million lives, disabled many more people, and caused innumerable economic losses around the globe. What can we learn from this tragedy? Are we ready for another Covid-19-like pandemic? Studies show that the majority of people with SARS-Cov-2 infection either show no symptoms or only mild to moderate clinical manifestations; only a small percentage develop severe Covid-19 disease, indicating that the clinical severity of Covid-19 disease is not determined only by the SARS-Cov-2 virus, but more importantly by how the host responds to the viral infection, what is known as natural immunity. Research of what enhances or weakens the natural immunity against viral infections and the practical application thereof is an important lesson one can learn from the pandemic. Research of natural immunity enhancing factors is summarized in this paper. One key characteristic of natural immunity against viral diseases is its non-specificity. The importance of this non-specificity helping to prevent and treat other infections of known or unknown viruses is also discussed. Calls for the clinical application of safe and inexpensive nutrients such as vitamin C in the prevention and treatment of Covid-19 have met significant resistance and objection from the medical authorities and the media since the pandemic outbreak. The main objection is the perceived lack of research and the absence of regulatory approvals. This raises a fundamental philosophical question: what is the primary goal of the medical profession? Facing a new viral pandemic like Covid-19 with no prior research, let alone any approved treatments, why is there opposition to known safe, inexpensive, widely available and often effective nutrients like vitamin C? Why are case reports and case series discounted or ignored rather than explored further to try to help more people? Is such objection protecting consumers or harming the public? Statistics show that viral epidemics and pandemics are occurring more frequently, with a recent review of epidemics and pandemics since 1600 concluding “ the yearly probability of occurrence of extreme epidemics can increase up to threefold in the coming decades.”1. When the next Covid-19-like pandemic of a new virus hits us, are we going to repeat the Covid-19 tragedy? Can improved emphasis on nutritional interventions to prepare for and respond to disease outbreaks mitigate future pandemics?
GLYCEMIC VARIABILITY INDICATORS BY CONTINUOUS GLUCOSE MONITORING AND HYPOGLYCEMIA RISK IN CHILDREN AND YOUNG ADULTS WITH TYPE 1 DIABETES
Authors: Sandoval Gustavo , Paz José , Finol Milexy , Villalobos Joalice
Published: October 2023

Background: Hypoglycemia is the main barrier to optimizing insulin treatment in people with type 1 diabetes, different risk factors have been studied and one of the mechanisms involved is glycemic variability. Aims: To assess hypoglycemia risk showed by the glycemic variability metrics: coefficient of variation (CV), continuous overlapping net glycemic action (CONGA), low blood glucose index (LBGI) and lability index (LI) in a group of children, adolescents, and young adults with type 1 diabetes. Methods: A group of 31 subjects with type 1 diabetes under 25 years were evaluated, data from professional continuous glucose monitoring records were studied, glycemic variability metrics, including CV, CONGA24, LBGI, and LI, were calculated. Correlation with percentage time of hypoglycemia under 54mg% was assessed. Multiple linear regression models were generated, univariate and multivariate analysis was also performed, area under curve of glycemic variability metrics was obtain from ROC curves analysis, the optimal cutoff points were calculated. Results: The average age was 14.5 years with a range of 5 to 24 years. The mean duration of diabetes was 6.6 ± 3.7 years, and the glycated hemoglobin mean value was 8.2% ± 2.1%. The average percentage of time for hypoglycemia alert was 4.23% (0.2 to 13%), while for clinically significant hypoglycemia was 4.55% (0 to 17.1%). LBGI with R= 0.913 and CV with R= 0.735 (p < 0.0001) expressed the highest degree of correlation with percentage of time in hypoglycemia, furthermore, after multivariate analysis, they showed the highest predictive load. CV expressed an AUC of 0.97, while LBGI was 0.95, both statistically significant (p<0.0005). The cut-off point for CV of 38% had sensitivity of 93% and specificity of 74% in detection of time in hypoglycemia under 54mg/dl, and the cut-off point for LBGI of 5.4 expressed sensitivity of 87% and specificity of 94%. Conclusions: Glycemic variability metrics studied outperformed the clinical variables as indicators of risk of hypoglycemia, and those with the greatest predictive power of hypoglycemia risk were LBGI and CV above 38%.

Published: October 2023

Objectives. Underweight patients with rheumatoid arthritis incur greater total and cardiovascular mortality compared to overweight or obese. We explored whether obesity confounded cardiovascular risk estimates and the potential utility of noninvasive coronary atherosclerosis assessment and cardiac damage biomarkers in optimizing risk prediction in obese patients with rheumatoid arthritis. Methods. We evaluated 150 participants undergoing screening atherosclerosis evaluation with coronary computed tomography angiography and follow-up over 6.0±2.4 years. Framingham 2008 modified general cardiovascular risk score was computed at baseline. Obesity was defined as waist circumference >88 cm in females and >102 cm in males. Serum highly-sensitive cardiac troponin I (hs-cTnI) and leptin were measured at baseline. Results. An interaction between the Framingham risk score and obesity on cardiovascular risk was observed (p=0.032); lower estimates were seen in obese (area under the curve-AUC 0.660, 95% CI 0.487-0.832) vs. non-obese patients (AUC 0.952, 95% CI 0.897-1.007, p=0.002). Likewise, risk estimates were inferior in patients with high (>22.1 ng/ml) vs. low leptin (AUC 0.618, 95% CI 0.393-0.842 vs. 0.874, 95% CI 0.772-0.976, p=0.042). In obese patients, sequential addition of the top highly-sensitive cardiac troponin I tertile values and extensive atherosclerotic plaque (>5 segments) information to a base model including the Framingham risk score alone significantly improved risk estimates, based on changes in net reclassification index (1.093 95% CI 0.517-1.574), integrated discrimination improvement (0.188, 95% CI 0.060-0.526), and AUC (0.179, 95% CI 0.058-0.378, p=0.02). The final, combined model accurately predicted 83.9% of incident cardiovascular events. Conclusion. Obesity attenuated cardiovascular risk estimate accuracy in patients with rheumatoid arthritis. Risk optimization employing non-invasive assessment of coronary atherosclerosis burden and serum cardiac damage biomarkers may warrant further study.
Strategies for Scientific Journals to Advance Diversity, Equity, Inclusion, Scholarship, Science, and Practice
Authors: Jimerson Shane
Published: October 2023

Background: Internationally, colleagues from minoritized groups and backgrounds are typically underrepresented within scientific journals. The benefits and importance of advancing diversity, equity, and inclusion, to further enhance science, scholarship, and practice are increasingly evident. Historical systems, structures, beliefs, policies, processes, and practices often advantage some and disadvantage others (e.g., racial, ethnic, gender minorities), thus, it is important to be reflective and proactive in advancing diversity, equity, inclusion (DEI) in scientific journals. Aims: It is imperative that leaders of scientific journals engage in intentional, purposeful, and sustained actions to advocate for and advance DEI, scholarship, science, and practice. There are numerous strategies that may be implemented by journal leadership to contribute to advancing DEI. Methods: Herein, a succinct summary of several recommendations is provided, followed by a case study illustrating the implementation of actionable strategies and current outcomes associated with the School Psychology Review journal. Strategies discussed include: (a) establishing individual and collective commitments to advocating for and advancing DEI as the foundation of our scholarship; (b) diversifying the journal leadership; (c) diversifying the editorial advisory board; (d) preparing future diverse journal leadership through mentored editorial fellowship programs, especially focused on early research career individuals; (e) mentoring future colleagues by establishing a student editorial board with members from diverse backgrounds; (f) focusing on special topics relevant to diverse and minoritized children, youth, families, and school communities; (g) making available professional-development opportunities and resources; and (h) establishing a journal action plan focused on advancing DEI. Results: The outcomes delineated in the present case study illustrate that the journal engages and benefits from the contributions of many distinguished colleagues from diverse and underrepresented backgrounds. Moreover, the journal contents that have followed from these efforts further advance science, scholarship, and practice that supports disadvantaged children, youth, and families, including those from minoritized groups. Conclusions: Colleagues, organizations, and entities involved with scientific journals around the world are encouraged to advance and sustain DEI efforts in science, scholarship, and practice.
