Topics in Graph Burning and Datalog
Authors: Moghbel Daniel 
Published: May 2022

<p>Graph burning studies how fast a contagion, modelled as a set of fires, spreads in a graph. The burning process takes place in discrete time-steps, or rounds. In each round, a fire breaks out at a given node (or vertex), thus burning it. Between rounds, fires from burning nodes spread to adjacent nodes. The burning number of a graph G, denoted b(G), is the minimum number of rounds necessary for every node of G to burn. We consider b(Gm,n), where Gm,n is the m × n Cartesian grid. For m = ω( √ n), the asymptotic value of b(Gm,n) was determined, but only the growth rate of b(Gm,n) was investigated in the case m = O( √ n). Accordingly, we provide new explicit bounds on b(Gc √ n,n) for valid c > 0. Graph burning is analogous to a pebble game, which typically involves the placement of pebbles on nodes of a graph. Burning of a node is comparable to a pebbling step (or pebbling move): the removal of two pebbles from a node, where one of the removed pebbles is placed on an adjacent node while the other is discarded. In a certain pebble game iii variant (discussed in Section 1.7), the existence of a winning strategy has an interesting characterization: expressibility of the relevant constraint satisfaction problem (or CSP) in the logic programming language Datalog. If a structure with a non-empty domain is restricted to relation symbols only, then we call that structure a template. We show that the CSP for any finite template admitting terms of the weak J ́onsson type has a property known as bounded pathwidth duality. This implies the expressibility of the complement CSP in linear Datalog, and places the CSP in NL.</p>

Corona Haikus
Authors: Gaudenzi Sandra 
Published: May 2022

When I moved from linear documentary production to the newly emerging field of interactive storytelling in the early 2000, I was excited by the potentialities of the Web, especially the possibility of co-creation in factual storytelling. Looking back, I can clearly see that what attracted me was the exploration of how factual narratives could make use of two affordances that are unique to digital media: user agency and interactivity. More than twenty years later, I am still experimenting with ways to use interactivity to facilitate co-creation of reality and move away from simple representation in documentary making (Gaudenzi 2013).
In this paper, I will use the Corona Haikus project (2020), to question the current understanding of user agency in participatory interactive narratives. I have chosen such project because I have personally been involved in it as a co-author, but also as a participant, and therefore I have both co-designed its user’s agency, and experienced it as a user. I will argue that agency in interactive documentary (i-doc) should be considered as a space of user empowerment that does not always have to affect the interactive narrative itself, because it can also be placed outside of the narrated story. The Corona Haikus example will be used to demonstrate that, in participatory narratives, deep individual and societal impact can be designed by mixing different types of mini-agencies and by orchestrating them as a journey of empowerment that is gradual and evolutive. Reflexive and evolutive agencies will be defined and presented as new ways to approach impact design in interactive narratives.
The Drama-Driven Model of Interaction and Optional Thinking
Authors: Ben-Shaul Nitzan 
Published: May 2022

Interactive films are defined here as an audiovisual narrative flow aimed at creating drama along with its characterizing suspense, curiosity, and surprise.
Interaction is defined as an audiovisual alignment that allows the interactor to intervene or steer the story progression in different ways (by voice recognition or touch screen options).
Interaction forms an added layer comparable to the addition of sound to silent movies. As with the addition of a soundtrack, an added interactive layer to the sound and image layers creates new narrative forms and audiovisual compositions. These new narrative forms include the new data-base narrative form discussed by Lev Manovich, often expressed through new digital enabled audiovisual compositions such as morphing.
However, adding an interactive layer poses a series of challenges which concern the need to script, direct, edit and design a coherent work when the story, the characters and the drama may not engender immersion due to out of fiction interactive actions. Hence, story multi-bifurcation upon interaction impedes the cognitive processing of the story logic. Likewise, interactive actions may obstruct the narrative flow, thereby leading to viewser split attention and miscomprehension.
This study suggests a solution to these common problems through the drama-driven model of interaction implemented in the interactive movie Turbulence.
Towards an Alternative Notion of the Interface
Authors: Ikebude Emeka 
Published: May 2022

The aim of this paper is to propose an alternative notion of the interface. While the existing notions of the interface suffice, there is a need for understanding the interface as an ecology, rather than as an object or technology. Scholars such as Branden Hookway, Alex Galloway, Nanna Verhoeff, and Heidi Rae Cooley understand the interface as "a relationship," "processes," "doing," and "habits," respectively. However, in consideration of the new and emerging social processes and transformations engendered by interfaces as platforms by which we understand and relate with the world in more specific ways, I argue that a notion of the interface as an ecology would enrich the discussion and provide an ecological boundary ‘object’ for thinking across disciplines. I examined the interface through etymological, epistemological, psychoanalytic, and artistic standpoints, as well as exploring the term's affective, material, and infrastructural dimensions. I conclude that an ecological notion of the interface would produce a more nuanced and performative understanding of the term and shift our focus away from the material form of interfaces, to the actions, intensities, and aesthetics of the interface. Ecology is critical to how we understand interfaces as it concerns the relationships between organisms and their environments, including the relationships between artists and their expressive media and installations, and the relationships between users and their interface platforms. The ecological notion of the interface refers to how we live in the networked, hypermediated space, relate with our technologies, and engage in artistic practices in all forms of interfaces.

Стаття присвячена дослідженню етапів відродження Військового інституту танкових військ Національного технічного університету «Харківський політехнічний інститут» (далі — ВІТВ НТУ «ХПІ») — єдиного й унікального військового освітнього закладу в Україні, що має свою школу підготовки кваліфікованих офіцерів-танкістів для Збройних Сил України.
Але, за висновками провідних українських військових вчених, самостій- ної системи підготовки офіцерських кадрів в Україні на 1991 рік не іс- нувало. Була тільки розрізнена мережа військових навчальних закладів, що створювало значні проблеми щодо трансформації системи військової освіти (СВО) відповідно до реальних потреб і можливостей Збройних Сил України.
У цих умовах Харківському вищому танковому командному училищу (далі — ХВТКУ) прийшлось доводити свою потрібність, долаючи перешкоди та труднощі, викликані проявами суб’єктивізму до створення СВО в Україні.
У статті також аналізується діяльність командування та колективу училища/інституту/факультету для повернення статусу провідного вищого військового навчального закладу.
Наведені факти щодо основних етапів формування навчального закладу, змін у його керівництві, структурі, завданнях та видатних особистостей.
Ключові слова: командне училище, офіцери-танкісти, курсанти, морально-психологічний стан, відродження.

Published: May 2022

ABSTRACT The main goals of the therapy of simple bone cyst (SBC) are to get the bone healing, prevent pathological fractures, and management of pain symptom. There are various methods of the SBC treatments, however they still remain controversial because of their healing rate and invasiveness of surgery. A total of 10 SBC patients were divided into two groups namely curretage with hydroxyapatite (HA) and decompression and percutaneous steroid injection (PSI). PSI was performed three times at intervals of each month. The mean followup of 12-26 months. Evaluation of functional outcome by Musculoskeletal Tumour Society (MSTS) score and supported with radiologically based on Chang criteria. There were 5 patients (proximal femur 2; proximal humerus 2, radius 1) performed curretage with HA therapy. Remaining 5 patients (proximal femur 3; proximal humerus 1; calcaneus 1) were performed PSI therapy. PSI group had better MSTS score, particulary at month 3 (55%) and month 6 (84%) than curettage with HA therapy (47% and 69.3%). Complete bone healing was found in both group at month 12 follow up, however solid union occurred faster in PSI group. PSI tends to have faster and better functional outcome than curettage and HA. Curettage with HA and PSI have similar complete bone healing at month 12 follow up. ABSTRAKTarget utama penalaksanaan simple bone cyst (SBC) adalah mencapat penyembuhan tulang yang sempurna, mencegah fraktur patologis dan mengatasi gejala nyeri. Ada beberapa metode penatalaksanaan SBC, namun demikian masih menjadi perdebatan dikarenakan perbedaan angka penyembuhannya dan jenis pembedahan yang invsif. Sepuluh pasien yang didiagnosis SBC dikelompokkan menjadi kelompok yang mendapat tindakan curretage dan pengisian defek dengan hydroxyapatite (HA) dan kelompok dekompresi dan percutaneous steroid injection (PSI). Prosedur PSIdilakukan sebanyak 3x dengan interval waktu satu bulan. Follow up dilakukan selama 12 – 26 bulan. Evaluasi luaran fungsional menggunakan Musculoskeletal Tumour Society (MSTS) score dan secara radiologi sesuai criteria Chang. Terdapat 5 pasien (2 femur proksimal, 2 humerus proksimal, dan 1 radius) yang dilakukan prosedur curretage dan pengisian defek dengan HA. Lima pasien sisanya ( 3 fenur proximal, 1 humerus proximal dan 1 calcaneus) dilakukan prosedur PSI. Luaran fungsional Kelompok PSI memiliki MSTS score yang lebih baik, khususnya pada bulan ke- 3 (55%) dan bulan ke-6 (84%) daripada kelompok curettage dengan HA (47% dan 69.3%). Penyembulan tulang sempurna menunjukkan hasil yang sama pada evaluasi bulan ke-12, tetapi solid union didapatkan lebih cepat pada kelompok PSI. Kelompok PSI memiliki kecenderungan solid union dan luaran fungsional yang lebih cepat daripada kelompok curettage dengan HA. Kedua kelompok mencapai penyembuhan sempurna pada bulan ke-12 follow up

Published: May 2022

Objetivou-se pesquisar a prevalência de sinais e sintomas depressivos dentre os discentes de graduação de cursos na área da saúde, de uma Universidade Federal, com projeto curricular pedagógico baseado em Metodologias Ativas de Ensino Aprendizagem, de um município no interior do nordeste brasileiro. Trata-se de um estudo transversal e observacional, de abordagem analítica, descritiva e quantitativa realizado por meio de questionários semiestruturados autoaplicáveis. Os sujeitos deste estudo foram discentes de graduação matriculados nos oito cursos da área de ciências da saúde. A pesquisa foi realizada entre fevereiro de 2018 a junho de 2019. Os dados quantitativos foram processados por meio do software Excel (Microsoft®) de forma descritiva. As influências centrais do módulo de tutorial foram ansiedade (77%; n=314), alterações de sono (79%; n=323), competitividade (66%; n=271), individualismo (60%: n=244) e estresse (83,7%; n=343); outros módulos obtiveram proporções menores. Cerca de 36% mudariam de instituição de ensino, 44% mudariam de curso; Aproximadamente 31% (n=129) dos discentes apresentava ao menos uma morbidade referida. Problemas Mentais Comuns foram o grupo de morbidade referida mais prevalente (49%; n=63). O Inventário Beck identificou que 35% (n=143) dos participantes apresentou algum grau de depressão; 2% (n=8) autoavaliou sua saúde como ‘ruim/muito ruim’; 8% (n=33) referiu utilizar medicamentos. O grupo de substâncias químicas mais frequentemente utilizadas foram os psicofármacos, tendo destaque os medicamentos ansiolíticos (43%; n=18) e antidepressivos (29%; n=12); 45% (n=20) relacionou o uso de medicamentos à entrada na Universidade. Entendemos que uma reflexão institucional, discente e docente sobre a aplicabilidade das metodologias ativas de ensino aprendizagem deve ser considerada.

Authors: Li Guoli , Liang Yumei , Yang Hongyu , Zhang Weiru , Xie Tingting 
Published: May 2022

Background: Ferroptosis is a novel mechanism of programmed cell death coined in 2012, which has been found to play important roles in human health and disease. In the past decade, ferroptosis research has seen booming growth worldwide. The aim of this study was to visualize the scientific outputs and research trends of ferroptosis in the field of cancer.Methods: The raw data of publications were retrieved from the Web of Science Core Collection on 19 December 2021. The information on the impact factor (IF) and Journal Citation Reports (JCR) division were obtained from the website of Web of Science. Two kinds of software (CiteSpace and VOSviewer) were used to perform visualized analysis.Results: From 2012 to 2021, a total of 1833 publications related to ferroptosis in cancer were identified for final analysis. The annual number of citations and publications grew exponentially over the past decade. China (1,092) and United States (489) had the highest number of publications; Central South University and Guangzhou Medical University were the most productive institutions. Daolin Tang and Scott J Dixon were the most active authors ranked by most productive and co-cited, respectively. The journals with the highest output and co-citation frequency were Biochemical and Biophysical Research Communications and Cell, respectively. Among the 1833 publications, four were identified with citations more than 1000 times. Six co-cited references had a citation burst duration until 2021. Analysis of keywords suggested the current research of ferroptosis in cancer clusters in 9 hotspots and newly emerging frontier may be “multidrug resistance”.Conclusion: Cancer research is the major area of active research in ferroptosis. Our results provide a global landscape of the ferroptosis research in cancer from 2012 to 2021, which serves as a reference for future studies in this field.

BackgroundCardiogenic shock (CS) alters whole body metabolism and circulating biomarkers serve as prognostic markers in CS patients. Percutaneous ventricular assist devices (pVADs) unload the left ventricle by actively ejecting blood into the aorta. The goal of the present study was to identify alterations in circulating metabolites and transcripts in a large animal model that might serve as potential prognostic biomarkers in acute CS and additional left ventricular unloading by Impella ® pVAD support.MethodsCS was induced in a preclinical large animal model by injecting microspheres into the left coronary artery system in six pigs. After the induction of CS, mechanical pVAD support was implemented for 30 min total. Serum samples were collected under basal conditions, after the onset of CS, and following additional pVAD unloading. Circulating metabolites were determined by metabolomic analysis, circulating RNA entities by RNA sequencing.ResultsCS and additional pVAD support alter the abundance of circulating metabolites involved in Aminoacyl-tRNA biosynthesis and amino acid metabolism. RNA sequencing revealed decreased abundance of the hypoxia sensitive miRNA-200b following the induction of CS, which was reversed following pVAD support.ConclusionThe hypoxamir miRNA-200b is a potential circulating marker that is repressed in CS and is restored following pVAD support. The early transcriptional response with increased miRNA-200b expression following only 30 min of pVAD support suggests that mechanical unloading alters whole body metabolism. Future studies are required to delineate the impact of serum miRNA-200b levels as a prognostic marker in patients with acute CS and pVAD unloading.

Published: May 2022

ObjectiveSome studies have demonstrated a bidirectional association between obesity and depression, whereas others have not. This discordance might be due to the metabolic health status. We aimed to determine whether the relationship between obesity and depression is dependent on metabolic health status.MethodsIn total, 9,022,089 participants were enrolled and classified as one of four obesity phenotypes: metabolically healthy nonobesity (MHNO), metabolically unhealthy nonobesity (MUNO), metabolically healthy obesity (MHO), and metabolically unhealthy obesity (MUO). We then divided the population into eight phenotypes based on obesity and the number of metabolic risk factors. Furthermore, the associations of eight phenotypes, based on obesity and specific metabolic risk factors, with depression were assessed.ResultAmong all participants, a higher risk of depression was observed for MUNO, MHO and MUO than for MHNO. The risk was highest for MUO (OR = 1.442; 95% CI = 1.432, 1.451). However, the association between MHO and depression was different for men and women (OR = 0.941, men; OR = 1.132, women). The risk of depression increased as the number of metabolic risk factors increased. Dyslipidemia was the strongest metabolic risk factor. These relationships were consistent among patients ≥ 45 years of age.ConclusionsThe increased risk of obesity-related depression appears to partly depend on metabolic health status. The results highlight the importance of a favorable metabolic status, and even nonobese populations should be screened for metabolic disorders.
