zkPAKE: A Simple Augmented PAKE Protocol
Authors: Mochetti Karina , Resende Amanda C. Davi , Aranha Diego F.
Published: July 2022

Human memory is notoriously unreliable in memorizing long secrets, such as large cryptographic keys. Password-based Authenticated Key Exchange (PAKE) protocols securely establish a cryptographic key based only on the knowledge of a much shorter password. In this work, an augmented PAKE protocol is designed and proposed for secure banking applications, requiring the server to store only the image of the password under a one-way function. The protocol is more efficient than alternatives because it requires fewer public key operations and a lower communication overhead.

Theorie U: Ein mediatives Verfahren für Transformationsprozesse?!
Authors: Larbi Monia Ben
Published: July 2022

Die Theorie U beschreibt einen Transformationsprozess, der sowohl die Komplexität von Systemen als auch die Relevanz von Bewusstsein ernst nimmt und auf die Öffnung von Verstand, Herz und Willen basiert. Hierzu wird im U-Prozess bewusst der »Download-Modus« verlassen, in dem wir in der Zukunft die Vergangenheit reproduzieren. In sieben Phasen führt der Prozess zunächst in die Tiefe, um dann Schritt für Schritt wieder zu konkretem Handeln aufzutauchen. Er bietet so einen Rahmen für den Einsatz einer großen Vielfalt von Methoden für innere und äußere Prozesse. Mediation und die Theorie U haben viele Gemeinsamkeiten, weshalb Mediator:innen mit ihren trainierten Kompetenzen im Bereich der Prozessdisziplin, des empathischen Zuhörens und der Ergebnisoffenheit sowie ihrem breiten Methodenschatz besonders gut für die Begleitung von U-Prozessen vorbereitet sind.
Das VREDE-Phasenmodell für Gruppenentscheidungen. Die Komplexität von Gruppenentscheidungen anerken- nen und meistern
Authors: Türk Elmar , Erharter Dorothea , Berger Dominik , Strigl Alfred
Published: July 2022

Das VREDE-Phasenmodell lässt Herausforderungen gemeinsamen Entscheidens verstehen und unterstützt Entscheidungsprozesse. Im Forschungsprojekt VREDE entwickelt ein Team aus Forschungs- und Beratungseinrichtungen sowie Softwarefirmen ein digitales Tool zur intuitiven Unterstützung von Gruppen- bzw. Team­entscheidungen. Ein zentrales Merkmal dabei ist die Verwendung widerstandsbasierter Bewertungsmethoden zur Entscheidungsfindung. In Recherchen fand sich kein geeignetes, umfassendes Modell gemeinsamen Entscheidens. So wurde das VREDE-Phasenmodell entwickelt. Der Hauptstrang des Modells beschreibt die Schritte komplexer Gruppenentscheidungen zunächst linear. Ein zyklisch-iteratives und auch fraktales Anwenden des VREDE-Phasenmodells ist ebenfalls möglich. Aus dem Modell wurden wiederum Anforderungen für das digitale Tool abgeleitet. Ergänzend werden Tools für Berater:innen und Moderator:innen entwickelt.
Dear organization, how will you address workplace conflicts in the post-pandemic world?
Authors: Manukyan Mushegh
Published: July 2022

The article explains that any organization - whether small or large, »best employer« or not so much - will benefit from a mediation program designed specifically to address potential workplace issues. The article demonstrates the need and effectiveness of an organizational mediation program that addresses workplace disputes, especially in the post-pandemic world. It focuses on the benefits of mediation as a process based on the example of the mediation program that is in place at UNICEF1, UNDP2, UNOPS3, UNFPA4, and UN5 Women. Those benefits include open communication, early and effective resolution, dedicated space for listening, neutrality, flexibility, professionalism, specialization in conflicts, focus on relationships, and confidentiality.

Effect of Dental Treatment on the Body Mass Index of Children Aged 3 - 6 Years Diagnosed with Early Childhood Caries: A Longitudinal Case-Control Study
Authors: Amirabadi Forough , Hashemi Elahe Sadat , Nikkhah Mahdi
Published: July 2022

Background: Dental caries is one of the most common childhood problems, which is associated with other diseases, such as malnutrition. Objectives: This study aimed to investigate the effect of early childhood caries (ECC) treatment on the body mass index (BMI) of children, aged 3 - 6 years. Methods: In this longitudinal case-control study, 96 children, aged 3 - 6 years, were recruited and divided into three groups (n = 32 per group). A questionnaire was completed for each child, and the decayed, missing, and filled teeth (DMFT) index was measured via clinical examination, according to the World Health Organization (WHO) criteria. Anthropometric measurements were performed in each group to assess BMI at baseline and after six months. The first two groups were diagnosed with ECC. For group I, a comprehensive dental treatment was performed under general anesthesia at baseline, while for group II, no treatment was applied during six months. Group III consisted of caries-free children. Data were analyzed using ANOVA, independent t-test, paired t-test, Mann-Whitney U test, and Kruskal-Wallis test (P < 0.05). Results: The mean and standard deviation of the DMFT index were 7.09 ± 2.40, 5.19 ± 1.72, and zero in groups I, II, and III, respectively. The BMI changes after six months were 0.11 ± 0.42, 0.00 ± 0.39, and -0.04 ± 0.64 kg/m2 in groups I, II, and III, respectively. The mean BMI significantly changed in the three groups within six months (P = 0.034). In group I, the BMI changes were significantly greater than the other two groups (P = 0.004). Conclusions: Although a significant negative relationship was found between ECC and BMI, oral hygiene and nutritional behavior were the main confounding variables. Based on the findings, treatment of ECC had a significant positive effect on BMI; therefore, it is important for healthcare professionals to identify and treat children at risk.

Published: July 2022

Background: Breaking Bad News (BBN) is a multidisciplinary and unpleasant task, and nurses play a vital role in this process as they are often exposed to such situations. It is a critical duty that has not been adequately addressed. Objectives: This study investigated the performance of nurses in academic hospitals affiliated with Guilan University of Medical Sciences (GUMS) regarding BBN. Methods: During 2020, eligible nurses were interviewed, and a questionnaire containing 16 items about environmental and psychical support was filled out. The ﬁrst 10 questions evaluated psychical support, and the next six assessed environmental support. Each question scored 10, "never," to 50, "always." Results: A total of 384 out of 410 nurses filled out the questionnaires, and a response rate of 93.65% was obtained. As shown, 346 (90.1%) responders were women, and 38 (9.9%) were men. Also, 289 (75.3%) had passed educational courses. A positive association was observed between psychical and environmental support and age (P = 0.007, P = 0.003) and years of experience (P = 0.013, P = 0.004). However, there was no significant difference respecting educational programs (P > 0.05). Conclusions: This study revealed that the current educational programs are not practical and could not induce a significant difference in nurses' answers. Effective interventions to improve nurses' communication skills are strongly warranted.
Preanalytic Competency Assessment: A Q-Probes Study Involving 46 Health Care Institutions, 447 Blood Collectors/Phlebotomists, and 2212 Individual Assessments
Authors: Stankovic Ana K. , Blond Barbara J. , Coulter Suzanne N. , Long Thomas , Lindholm Paul F.
Published: July 2022

Context.—

Health care organizations face a challenge of assessing preanalytic competency of blood collectors/phlebotomists (BC/Ps).

Objective.—

To pilot a novel methodology for BC/P preanalytic competency assessment and identify potential areas for improvement.

Design.—

Study participants identified preanalytic errors present in 5 blood collection video vignettes. Submitted error descriptions were categorized and then consolidated into a list of standardized required errors for evaluation.

Results.—

The correct identification of required error rates across all videos viewed by 447 BC/Ps from 46 institutions ranged from 0.7% to 91.9%. The median phlebotomist score across all 5 videos was 55.9% for 440 eligible blood collectors and ranged between 38.2% (10th percentile) and 70.6% (90th percentile). The median institutional score from 42 eligible institutions was 55.9% (range, 43.3%–65.3% for the 10th to 90th percentiles). There were no significant associations between any laboratory practice characteristics and the institutional average overall phlebotomist scores. The following phlebotomist characteristics were significantly associated with overall phlebotomist scores: level of education (P = .01), having phlebotomy technician (American Society for Clinical Pathology) certification compared with no or other certifications (P = .002), years of experience in collecting blood specimens (P = .01), and higher average number of venipuncture specimens collected per shift (P = .001).

Conclusions.—

Improvement of the awareness and knowledge of correct blood collection practices is needed, because the best performers (90th percentile) did not recognize approximately one-third of the errors. Using hypothetical blood collection scenarios that incorporate performance errors may be a way to assess preanalytic competency of BC/Ps and create opportunities for continuous improvement.
Resident Depression and Burnout During the COVID-19 Pandemic: A Survey of Canadian Laboratory Medicine Trainees
Authors: Han Rachel , Hahn Elan , Done Susan J. , Pun Cherry , Shivji Sameer , Lu Fang-I
Published: July 2022

Context.—

Resident physicians face a higher rate of burnout and depression than the general population. Few studies have examined burnout and depression in Canadian laboratory medicine residents, and none during the COVID-19 pandemic.

Objective.—

To identify the prevalence of burnout and depression, contributing factors, and the impact of COVID-19 in this population.

Design.—

An electronic survey was distributed to Canadian laboratory medicine residents. Burnout was assessed using the Oldenburg Burnout Inventory. Depression was assessed using the Patient Health Questionnaire 9.

Results.—

Seventy-nine responses were collected. The prevalence of burnout was 63% (50 of 79). The prevalence of depression was 47% (37 of 79). Modifiable factors significantly associated with burnout included career dissatisfaction, below average academic performance, lack of time off for illness, stress related to finances, lack of a peer or staff physician mentor, and a high level of fatigue. Modifiable factors significantly associated with depression further included a lack of access to wellness resources, lack of time off for leisure, and fewer hours of sleep. Fifty-five percent (41 of 74) of participants reported direct impacts to their personal circumstances by the COVID-19 pandemic.

Conclusions.—

Burnout and depression are significant issues affecting Canadian laboratory medicine residents. As the COVID-19 pandemic continues, we recommend the institution of flexible work arrangements, protected time off for illness and leisure, ongoing evaluation of career satisfaction, formal and informal wellness programming with trainee input, formal mentorship programming, and a financial literacy curriculum as measures to improve trainee wellness.
When Disruption is the New Normal: The Impacts of the COVID-19 Pandemic on Technical Services in US Academic Libraries
Authors: Tosaka Yuji , Weng Cathy
Published: July 2022

As college campuses closed for in-person classes and shifted to online instruction due to the COVID-19 pandemic in spring 2020, US academic libraries also scrambled to provide continued access to library services and resources to support remote learning, teaching, and research. One important question is how academic library technical services responded to the public health emergency and adapted to new challenges to continue to serve the academic community. This paper illustrates a survey study that investigated the impact of the COVID-19 pandemic on US academic library technical services units in terms of disruptions and alterations of existing normal operations. The study revealed that technical services librarians and staff made determined efforts to continue performing as much of their pre-pandemic work as possible under the challenging circumstances. Unsurprisingly, library collection building practices and collection budgets were seriously affected by the pandemic. The study also showed the limitations of institutional preparedness and response to the public health emergency. Lastly, the study explored the personal experiences and perceptions of working from home during the pandemic and found no significant changes in work productivity, motivation, or concentration.
Polyvalence of an open plan apartment: Characteristics and spatial organization principles
Authors: Alfirević Đorđe , Simonović-Alfirević Sanja
Published: July 2022

Polyvalence (gr. poly multi, nlat. valentia value - multivalued, ambiguous, multipurpose) is a term that has a wide range of uses in science and art. Polyvalence usually implies different ways (regimes) of using the same space, i.e., the adaptability of space to different human needs, with minimal physical modifications. It is a common opinion in science that the term polyvalence in residential architecture primarily refers to the level of an entire apartment or house, i.e., to the possibility of reorganizing the internal structure (conversion of the premises), which can be seen as a broader interpretation of the term. On the other hand, there is a narrower interpretation which refers to the polyvalence of a part of an apartment, to a particular space or room, i.e., to the possibility of overlapping housing functions at different times in the same space, a so-called open plan. The research considers the concepts of spatial organization in polyvalent residential spaces with an open plan. The scientific analysis of reference sources, the interpretation and analysis of characteristic examples, and the deductive method, were used to investigate polyvalent open-plan living spaces, with the aim of ascertaining their most important characteristics and the principles of their spatial organization.
An architectural reserve as a heritage preservation structure: The example of Stara Planina villages
Authors: Ljubenov Gorica , Vuksanović-Macura Zlata
Published: July 2022

This paper analyses the conditions and possibilities with regard to preserving vernacular architecture in the area of Stara Planina Mountain, Serbia. The field research, conducted from 2003 to 2015, recorded and documented architectural heritage in the villages on the western slopes of Stara Planina Mountain. The areas of Gornji Visok and Zabrdje on the slopes of Vidlič were primarily explored. Considering that the valuable architectural heritage in this area is in a state of alarming threat, and disappearing at high speed, the article discusses the possibilities with regard to its preservation through the formation of an architectural reserve, as a spatially defined and functionally unique place based on a synthesis of created and natural heritage. The reserve's structure would consist of architectural cores that are entire villages, or isolated localities with authentic houses of vernacular architecture. The architectural cores would be interconnected by road infrastructure, forming a specific architectural route. The constituent elements of the reserve would also include natural heritage, and geomorphological, geological, hydrological and hydrogeological features. The formation of the architectural reserve also aims to utilise built and natural structures, educate inhabitants and visitors, and develop tourism. In that way, the potential for financing the preservation of the unique architectural heritage of Stara Planina could be initiated.

Published: July 2022

Introduction Chronic non-communicable diseases (CNCD) are a major public health issue in many countries worldwide. The most significant risk factors for CNCD development are smoking, hypertension, hypercholes-terolaemia, alcohol consumption, obesity, poor diet and lack of physical activity. Assessment of prevalence and distribution of risk factors relat-ed to chronic noncommunicable diseases in the population of women of Central Serbia and defining the needs for preventive activities are the main objectives of this study. Cross-sectional study was conducted using a sample of 1182 women in their reproductive period (15-49 years of age) from Central Serbia, in the period from April 2019 to November 2021. The study was conducted by teachers and students of the Faculty of Medical Sciences at the University in Kragujevac using the methodology and tools of the STEP-wise Approach to Noncommunicable Diseases Risk Factor Surveillance of the World Health Organisation (STEPS) with the support of the Ministry without portfolio charged with demographics and popula-tion policy of the Republic of Serbia. Commercial, standard SPSS soft-ware package version 18.0 (The Statistical Package for Social Sciences software (SPSS Inc, version 18.0, Chicago, IL)) was used for statistical calculations. In our study, 62.5% of the women consumed tobacco prod-ucts each day,while 68.5% had consumed alcohol in the last 12 months. A quarter of the respondents (27.9%) consumed fruit every day of the week, and a little under a half (43.2%) consumed vegetables every day. In addition, 40.1% of the women claimed that they added salt to their food before even tasting it, and one fifth said that they engaged in at least 10 continual minutes of high-intensity physical exercise (fitness, recreation, sports) in their free time. In conclusion, risk factors for CNCD exist among the women in Central Serbia, so it is necessary to undertake appropriate preventative measures.
The basic properties of the information dimension of the security environment
Authors: Miljković Milan , Jevtić Dragan , Stojičević Slobodan
Published: July 2022

The information dimension of the modern security environment is characterized by complexity, the abundance of unstructured information and numerous conflicts that are fought through information warfare. The stated complexity of the modern information dimension and the problem of correctly perceiving the security environment raises the question of application of modern and proven methods for their analysis. These methods are a useful tool for understanding the information dimension, especially if it is about a foreign or opposing environment, and they help organizing, synthesizing, and applying information as a key part of communication planning and strategic thinking and decision making. Structural analysis of the information dimension includes the analysis of: a) elements of the information dimension, primarily information infrastructure, systems and devices for collecting, transmitting, processing and delivering information, information and their flows, as well as personnel and organizations performing various activities related to the information; b) areas of the information dimension, i.e. physical, cognitive, and information areas; c) levels of the information dimension, which are divided into global, national and military-security levels; and d) actors of the information dimension, primarily individuals, non-state and state actors, directing the analysis to their ability to act in the information dimension, i.e. performing information operations. The functional phase of information dimension analysis, on the other hand, contains the following phases: 1) defining the information dimension, 2) describing the effects of the information dimension, using PMESII and ASCOPE matrix, 3) assessing information situation and threat, within which a possible pattern and the doctrine of information action of the opponent in a specific situation are determined, and 4) determining the directions of action of the opponent in the information dimension. It can be concluded that only a comprehensive analysis, which considers all the elements of the structure of the information dimension, as well as the elements of functional analysis, provides the military with a complete understanding of the information dimension and functional information on the possibility of shaping the information dimension for the purpose of acting against the opposing forces easier accomplishing of gains.
The partition of Kosovo and Metohija: Reality or delusion?
Authors: Proroković Dušan
Published: July 2022

Although the topic of dividing Kosovo and Metohija into the Serbian and Albanian part was mostly avoided by officials, both national and international, it has been discussed in public since the 1960s, mostly owing to Dobrica Ćosić. By choosing the concept of "demarcation" as "the final solution" during the negotiations between Belgrade and Priština from 2018, the thinking about partition has been reaffirmed. At one point, the highest officials of the Republic of Serbia have announced that the idea represents an official position. However, there are four problems with this approach. Firstly, this concept has never been concretized at the official level. The proposals by Branislav Krstić and Dušan Bataković were probably considered, but not adopted as a part of the Serbian state strategy. Secondly, there was no preparation of the public for such an outcome or that work was sloppily done at the moment when the proposal, at least in principle, was declared official. Hence, the "shallow support" was relative, which is why the legitimacy of the idea was questioned. Thirdly, there are no serious indications that the Albanian party is interested in such an outcome. The attitude of politicians, their readiness to discuss this topic is not well accepted by the Albanian public, thus such a course of action is disputed. Even if a consensus was reached in the negotiations and some kind of agreement was signed with such content, it would remain open how long-term it would be and what consequences there would be in the future. The indications that demarcation can be considered are conditioned in such a way that it would actually represent essential delimitation, exchange of territories, with the accompanying request to continue the process of enlarging the Albanian ethno space. Fourthly, there is no agreement of international factors to carry out something like that. Also, when certain proposals were finally considered and "leaked to the public", they were in line with what the Albanian party was asking for and largely respected the Albanian interests. In the current format of negotiations, and in accordance with the position of the key Western countries responsible for the current situation in Kosovo and Metohija, the implementation of the concept of demarcation cannot have positive effects for Serbia, viewed from a short or long-term perspective whatsoever. The path to the partition of Kosovo and Metohija, just when such a concept would be accepted by international actors as a solution, is full of uncertainty and ambiguity. It is difficult to report such an idea without many consequences after its execution. If partition is to be considered as a solution, long and thorough preparation is necessary, taking into account all its aspects including the new territorial reconfiguration of the postYugoslav space, the implications for regional relations, security and stability.
El luto en los parlamentos autonómicos.
Authors: MENA GARCÍA Tomás
Published: July 2022

La muerte nos iguala a todos, pero los ritos funerarios que se desarrollan con posterioridad dependen del puesto ocupado por el fallecido en la sociedad o en el seno de cada organismo o institución. A ello no son ajenos los parlamentos autonómicos, que a lo largo de estos años han ido desarrollando normativas, usos o costumbres diferentes para afrontar la muerte de sus integrantes cuando esta acontece. Poco imaginan los cargos electos que el mismo día de su toma de posesión, un funcionario ya tiene previsto qué hacer en caso de óbito, porque las prisas son malas consejeras y se corre el riesgo de incurrir en desigualdades y agravios comparativos. Con este trabajo pretendo dar a conocer la labor realizada por los Servicios de Protocolo cuando se han enfrentado al luto en las siguientes ocasiones: fallecimiento de presidentes en ejercicio, expresidentes, expresidentes autonómicos, parlamentarios/as, exparlamentarios/as, o personal al servicio se las cámaras. La función de los Servicios de Protocolo de las cámaras legislativas no se caracteriza por el contacto con otros colegas autonómicos, por lo que creo oportuno contar con un estudio recopilatorio al que acudir en caso de duda o necesidad, el cual dedicará un apartado especial al quehacer del Parlamento de Navarra en esta materia.
Melancolía y temporalidad exílica
Authors: Pérez Baquero Rafael
Published: July 2022

El propósito de este artículo es el de analizar las condiciones y potencialidades derivadas de la fijación en el pasado que caracteriza a algunas producciones culturales del exilio español de 1939. Profundizando en la noción de “temporalidad exílica”, recuperaremos el debate contemporáneo en torno a su proyección en la España democrática. Desde el interior del mismo, ofreceremos argumentos  a través de una indagación filosófica sobre la noción de melancolía que intenta trascender los enfoques clásicos respecto a la misma. En base a esta interpretación, defenderemos que la recuperación de un pretérito doloroso por parte de los exiliados que regresaron a España no es un índice de una memoria patológica y auto-complaciente. Al contrario, es la semilla para revelar los déficits y lagunas del proceso transicional español; en lo que se refiere a la recuperación simbólica y material de las víctimas asociadas al bando vencido en la guerra civil.
La tribuna vacante
Authors: Fernández Vega Juan Luis
Published: July 2022

Este trabajo examina cómo, para ocupar la tribuna vacante del filósofo-orador José Ortega y Gasset, el exiliado Eduardo Nicol elaboró el emergente problema contemporáneo de la relación entre retórica y filosofía. Esta cuestión atañe tanto al qué como al para qué de la filosofía. ¿Hay un “grado cero” retórico en el pensamiento? Y si existe, ¿es el grado óptimo, considerando la meta humana de la filosofía? Nicol respondió ambas preguntas (1) avanzando sobre la semiótica fenomenológica de Husserl (y Heidegger), para establecer en la comunicación humana la constitución simultánea de expresión, significación y objetividad; y (2) renunciando a la brillantez ensayística de Ortega como paradigma de influencia cultural de la filosofía. Pero, en el primer camino, no extrajo todas las consecuencias de su expresionismo; en el segundo, hubo de admitir una norma retórica algo diferente del grado cero, ya que la humanidad estaba en peligro. El caso de Nicol, en diálogo con todas las corrientes de la filosofía contemporánea, reafirma el lugar central que en ellas viene ocupando la semiótica.

Identidad nacional y valores de la Unión Europea: límites a una interpretación extensiva del artículo 4.2 TUE
Authors: Cruz Mantilla de los Ríos Pablo
Published: July 2022

La identidad nacional es una categoría jurídica del Derecho de la Unión Europea que está siendo objeto de una controvertida interpretación en clave soberanista por parte de algunos líderes políticos, así como por ciertos Tribunales Constitucionales nacionales en los últimos años. Asistimos a una reciente corriente jurisprudencial en consonancia con el auge de movimientos políticos de impronta autocrática y populista que defienden un modelo de democracia iliberal en nuestro continente, particularmente en Hungría y Polonia. Así pues, se sostiene una concepción extensiva de la identidad nacional que pretende articularse como un mecanismo de resistencia nacional de carácter absoluto e imponderable frente a la acción del Derecho de Unión. En estas circunstancias, este artículo aspira a analizar críticamente esta jurisprudencia nacional, que presenta serias dudas de compatibilidad con una interpretación histórica, literal y sistemática de los Tratados y, especialmente, con los valores de la Unión Europea. A estos efectos, se abordará un estudio de los orígenes y de la evolución histórica de esta disposición, una categorización de la noción de identidad nacional, un análisis jurisprudencial nacional y supranacional, y el concepto de identidad europea con el propósito de poner en tela de juicio la desviada construcción jurisprudencial auspiciada por algunos Tribunales Constitucionales nacionales de Europa del este.
Espacios de Civilización: El Caso de los Lavabos Públicos en Nanjing, China
Authors: Romero Moreno Aran
Published: July 2022

El artículo toma los lavabos públicos de la ciudad de Nanjing, China, como caso de estudio particular para analizar el concepto de civilización desde un punto de vista espacial y praxeológico. Aplicando una mirada antropológica ―sirviéndose de descripciones y viñetas etnográficas– el autor relaciona las lógicas civilizatorias locales, propias de un contexto histórico y cultural particularmente chino, con las (ideo)lógicas mercantiles del capitalismo global, revelando una lucha de posiciones y contradicciones que suponen un límite claro para la noción normativa de civilización y, quizás, para el propio sistema capitalista.

The performance of magnetocaloric effect materials is one of the key factors restricting the development of magnetic refrigeration technology. Materials with anisotropic magnetocaloric effect can be used in the rotary magnetic refrigeration technology, which is beneficial to the simplification of refrigeration devices. In this work, the magnetic properties, magnetocaloric effects, and magnetic anisotropies of rapidly quenched HoCoSi compounds are investigated. At low temperatures below Tt = 5.7 K, the HoCoSi ferromagnetism and helical magnetism coexist. With the increase of temperature, the HoCoSi undergoes a second-order phase transition from ferromagnetic (FM) to paramagnetic (PM) phase at TC = 13.7 K. Both XRD and SEM show that the HoCoSi has a preferred orientation. In order to obtain a large magnetocaloric effect and to determine the effect of preferred orientation on magnetism and magnetocaloric effect, the isothermal magnetization curves of the 10 m/s–HoCoSi fast quenched belt in the directions of H parallel and perpendicular to texture around the Curie temperature are analyzed. The corresponding magnetic entropy change (–ΔSM) and magnetic refrigeration capacity (RC) are calculated. Under the magnetic field changing from 0 to 5 T, the value of –ΔSM is 22 J/(kg·K) in the direction of H parallel to the texture and 12 J/(kg·K) in the direction of H perpendicular to texture , and their corresponding values of RC(RCP)are 360 (393.8) J·kg–1 and 160 (254.4) J/kg. The value of –ΔSM reaches 12.5 J/(kg·K)even at μ0H = 0–2 T in the direction of H parallel to the texture. It is obvious that the 10-m/s-HoCoSi fast quenching belt shows a large low-field magnetocaloric effect and obvious magnetic anisotropy, which is expected to be used to realize the magnetic refrigeration technology of rotating samples.

Pigments homologous to the green fluorescent protein (GFP) have been proposed to fine-tune the internal light microclimate of corals, facilitating photoacclimation of photosynthetic coral symbionts (Symbiodiniaceae) to life in different reef habitats and environmental conditions. However, direct measurements of the in vivo light conditions inside the coral tissue supporting this conclusion are lacking. Here, we quantified the intra-tissue spectral light environment of corals expressing GFP-like proteins from widely different light regimes. We focus on: (1) photoconvertible red fluorescent proteins (pcRFPs), thought to enhance photosynthesis in mesophotic habitats via wavelength conversion, and (2) chromoproteins (CPs), which provide photoprotection to the symbionts in shallow water via light absorption. Optical microsensor measurements indicated that both pigment groups strongly alter the coral intra-tissue light environment. Estimates derived from light spectra measured in pcRFP-containing corals showed that fluorescence emission can contribute to >50% of orange-red light available to the photosynthetic symbionts at mesophotic depths. We further show that upregulation of pink CPs in shallow-water corals during bleaching leads to a reduction of orange light by 10–20% compared to low-CP tissue. Thus, screening by CPs has an important role in mitigating the light-enhancing effect of coral tissue scattering and skeletal reflection during bleaching. Our results provide the first experimental quantification of the importance of GFP-like proteins in fine-tuning the light microclimate of corals during photoacclimation.

Deletion of mitochondrial DNA in eukaryotes is currently attributed to rare accidental events associated with mitochondrial replication or repair of double-strand breaks. We report the discovery that yeast cells arrest harmful intramitochondrial superoxide production by shutting down respiration through genetically controlled deletion of mitochondrial oxidative phosphorylation genes. We show that this process critically involves the antioxidant enzyme superoxide dismutase 2 and two-way mitochondrial-nuclear communication through Rtg2 and Rtg3. While mitochondrial DNA homeostasis is rapidly restored after cessation of a short-term superoxide stress, long-term stress causes maladaptive persistence of the deletion process, leading to complete annihilation of the cellular pool of intact mitochondrial genomes and irrevocable loss of respiratory ability. This shows that oxidative stress-induced mitochondrial impairment may be under strict regulatory control. If the results extend to human cells, the results may prove to be of etiological as well as therapeutic importance with regard to age-related mitochondrial impairment and disease.

Of all the non-human primate species studied by researchers, the rhesus macaque (Macaca mulatta) is likely the most widely used across biological disciplines. Rhesus macaques have thrived during the Anthropocene and now have the largest natural range of any non-human primate. They are highly social, exhibit marked genetic diversity, and display remarkable niche flexibility (which allows them to live in a range of habitats and survive on a variety of diets). These characteristics mean that rhesus macaques are well-suited for understanding the links between sociality, health and fitness, and also for investigating intra-specific variation, adaptation and other topics in evolutionary ecology.

Viruses generally are defined as lacking the fundamental properties of living organisms in that they do not harbor an energy metabolism system or protein synthesis machinery. However, the discovery of giant viruses of amoeba has fundamentally challenged this view because of their exceptional genome properties, particle sizes and encoding of the enzyme machinery for some steps of protein synthesis. Although giant viruses are not able to replicate autonomously and still require a host for their multiplication, numerous metabolic genes involved in energy production have been recently detected in giant virus genomes from many environments. These findings have further blurred the boundaries that separate viruses and living organisms. Herein, we summarize information concerning genes and proteins involved in cellular metabolic pathways and their orthologues that have, surprisingly, been discovered in giant viruses. The remarkable diversity of metabolic genes described in giant viruses include genes encoding enzymes involved in glycolysis, gluconeogenesis, tricarboxylic acid cycle, photosynthesis, and β-oxidation. These viral genes are thought to have been acquired from diverse biological sources through lateral gene transfer early in the evolution of Nucleo-Cytoplasmic Large DNA Viruses, or in some cases more recently. It was assumed that viruses are capable of hijacking host metabolic networks. But the giant virus auxiliary metabolic genes also may represent another form of host metabolism manipulation, by expanding the catalytic capabilities of the host cells especially in harsh environments, providing the infected host cells with a selective evolutionary advantage compared to non-infected cells and hence favoring the viral replication. However, the mechanism of these genes' functionality remains unclear to date.
Effective attributed network embedding with information behavior extraction
Authors: Hu Ganglin , Pang Jun , Mo Xian
Published: July 2022

Network embedding has shown its effectiveness in many tasks, such as link prediction, node classification, and community detection. Most attributed network embedding methods consider topological features and attribute features to obtain a node embedding but ignore its implicit information behavior features, including information inquiry, interaction, and sharing. These can potentially lead to ineffective performance for downstream applications. In this article, we propose a novel network embedding framework, named information behavior extraction (IBE), that incorporates nodes’ topological features, attribute features, and information behavior features within a joint embedding framework. To design IBE, we use an existing embedding method (e.g., SDNE, CANE, or CENE) to extract a node’s topological features and attribute features into a basic vector. Then, we propose a topic-sensitive network embedding (TNE) model to extract a node’s information behavior features and eventually generate information behavior feature vectors. In our TNE model, we design an importance score rating algorithm (ISR), which considers both effects of the topic-based community of a node and its interaction with adjacent nodes to capture the node’s information behavior features. Eventually, we concatenate a node’s information behavior feature vector with its basic vector to get its ultimate joint embedding vector. Extensive experiments demonstrate that our method achieves significant and consistent improvements compared to several state-of-the-art embedding methods on link prediction.

Restoration is the natural and intervention-assisted set of processes designed to promote and facilitate the recovery of an ecosystem that has been degraded, damaged, or destroyed. However, it can also have an adverse effect on the environment. Thus, assessing an ecological restoration project’s impact is crucial to determining its success and optimum management strategies. We performed a meta-analysis concerning the environmental outcomes during the years 2000–2015 resulting from the “Grain for Green” Project (GFGP) implementation in the Loess Plateau (LP). Data were gathered from 40 peer-reviewed English-language articles chosen from a pool of 332 articles. The results showed that, on average, GFGP increased forest coverage by 35.7% (95% CI [24.15–47.52%]), and grassland by 1.05% (95% CI [0.8–1.28%]). At the same time, GFGP has a positive impact on soil carbon (C) sequestration, net ecosystem production (NEP), and net primary production (NPP), from the years 2000 to 2015 by an average of 36% (95% CI [28.96–43.18%]), 22.7% (95% CI [9.10–36.79%]), and 13.5% (95% CI [9.44–17.354%]), respectively. Soil erosion, sediment load, runoff coefficient, and water yield were reduced by 13.3% (95% CI [0.27–25.76%]), 21.5% (95% CI [1.50–39.99%]), 22.4% (95% CI [5.28–40.45%]) and 43.3% (95% CI [27.03–82.86%]), respectively, from the years 2000 to 2015. Our results indicate that water supply decreased with the increase of vegetation coverage. Therefore, to balance the needs for green space, GFGP policies and strategies should recover, enhance, and sustain more resilient ecosystems.
