COMO SER INTENCIONALISTA E DISPOSICIONALISTA
Authors: Leclerc André
Published: February 2021

Intentionalists believe that intentionality, the relational property of being about something, is constitutive of mentality. Brentano’s thesis says: 1) the mental is intentional; 2) nothing physical exhibits that property. Dispositionalism, I believe, should be extended to include all mental properties, which are also dispositional and realized physically in the brain, like the solubility of sugar which is realized in its molecular structure. My aim is to show how we can be intentionalists (by accepting the first part of Brentano’s Thesis) and dispositionalists at the same time (by accepting that mental states, acts and events have a physical base of realization). In a nutshell: the intentional is the manifestation of mental dispositions. Dispositions in general, psychological dispositions in particular, are two-sided and presupposes, on the one hand, a physical realization, and a manifestation which is properly mental, on the other. Something has to be said about language in that context, because public representations instantiate semantic properties which also are intentional, and many of our mental states have their content specified by the use of a sentence belonging to a public language.

Authors: Batista Bruno Cássio Rodrigues , Ribas Rovadávia Aline de Jesus , Paula Geraldo Donizetti de
Published: February 2021

Neste trabalho, foi analisado o desempenho térmico de um edifício do Instituto Federal de Educação, Ciência e Tecnologia do Sudeste de Minas Gerais - Campus Barbacena, Brasil. A simulação foi feita usando o software EnergyPlus. Foi avaliado o desempenho térmico do edifício existente e da proposta de projeto para substituir o sistema de cobertura do edifício existente, levando em consideração as condições de ventilação natural. A simulação numérica foi realizada em dois modelos. O primeiro modelo corresponde à edificação construída e utilizada que é chamado de Modelo_1. O segundo modelo, é uma proposta de projeto para recuperação da estrutura do galpão construído sobre a piscina aquecida que é chamado de Modelo_2. A fim de facilitar a modelagem, assumiu-se a configuração de apenas uma zona térmica. Os dados bioclimáticos utilizados foram da cidade de São João del Rei-MG. Não foi considerada a presença de fontes internas de calor, dessa forma o perfil de ocupação da edificação foi desconsiderado. As simulações foram realizadas para dias típicos de verão e inverno. O Modelo_1 não atendeu aos critérios de desempenho térmico mínimo, entretanto o Modelo_2 atendeu aos critérios de desempenho térmico mínimo para os dias típicos de verão e de inverno. A partir dos resultados obtidos, pode-se inferir que a substituição de alguns materiais de fechamento influencia diretamente no desempenho térmico do edifício, melhorando o conforto do usuário.
Bollywood’s Angromance: Toxic Masculinity and Male Angst in Tere Naam and Kabir Singh
Authors: Viswamohan Aysha Iqbal , ChaudhurI Sanchari Basu
Published: February 2021

The article draws on specific theories of hegemonic masculinity through the performances of toxic masculinity to conceptualize “angromance” (our term for “angry romance”) in recent mainstream Hindi cinema. It analyzes seminal discourses associated with sadomasochistic heroes in commercially successful Bollywood films Tere Naam (“In Your Name,” Satish Kaushik, 2003), and Kabir Singh (Sandeep Reddy Vanga, 2019). The attempt is to understand how these films, separated by nearly two decades, deploy standard conceits of Bollywood, which tend to normalize problematic and hypermasculine traits. The protagonists’ metamorphosis into tragic heroes during the course of the narrative also reinforces the denial of agency of the female protagonists. Such transformation invokes compassion toward the tragic hero, and is marked by a shift in his physical appearance, leading toward self-destruction, bordering on masochism. This performance of angst was manifested in the character of Radhe from Tere Naam and his styling through the course of the film. In the case of Kabir Singh, the leading man’s portrayal as tragic hero was remarkable for his unkempt looks, alcoholism, substance abuse, and increasingly misogynistic attitude. Quite evidently, both narratives draw upon characteristics from traditional portrayals of obsessive love on Bollywood’s silverscreen. In recent times, representations of misogyny and sexism in popular culture have received a backlash, particularly after the exponential rise in crimes against women. Our attempt is to comprehend how Bollywood assembles various masculinities to validate the performance of angromance and, subsequently, the limitations of such masculinities.
Economic and Technical Modeling of the Lebanese Crypto Currency: Implication for a Digital-Lira (DL)
Authors: Hamdar Bassam , Saad Tarek , Hamdar Mohammad
Published: February 2021

Since 1997, the Lebanese pound has been pegged to the U.S dollar at a fixed rate, and at every crisis, people rush to banks to convert their LBP accounts into U.S.D causing a high demand for foreign currencies. Fear and uncertainty finds its way to the market, and the general sentiment often causes various sectors of the economy to be negatively affected. Lebanon is highly dependent on the U.S.D and the LBP had slowly become nothing but a symbol of independence and a heritage that tells the story of “Lebanon”. This paper will examine the century’s most aspiring technology to see how it can be implemented to create a new form of national currencies, and how such a technology can incorporate basic to complex monetary policies in an automated manner to gain value, and have a controlled inflation through a pre-programmed system. This paper will also break down the “Bitcoin” conditions and show how it can be modified to fit a locally produced national crypto-currency for Lebanon that will be referred to as “Digi-Lira”. Finally, this paper will highlight the economic impact of the Digi-Lira on demand, investment, international trade, remittances, the unbanked population, and the banking sector.
Uma análise sobre as ilustrações e a temática da morte em Harvey: como me tornei invisível
Authors: Segabinazi Daniela Maria , Barbosa Jaine Sousa
Published: February 2021

A morte está presente nos textos literários destinados ao público infantil, e, embora a temática ainda seja considerada tabu para muitos, o número de obras que a utilizam como eixo central da narrativa vem crescendo ao longo dos anos, bem como cresce o número de obras ilustradas, sendo muitas delas compostas apenas por imagens. Nas páginas dos livros, a morte assume várias facetas, e na literatura para crianças isso não é diferente. Nessa relação entre texto e imagem que esse trabalho surgiu. Assim, analisamos como as ilustrações contribuem para a construção da representação da morte na obra Harvey, como me tornei invisível, de Hervé Bouchard e Janice Nadeau (2012), enfatizando não apenas a própria representação da morte criada a partir da narrativa, mas, especialmente, como as imagens atuam tanto na construção dos significados dos textos quantos nos desdobramentos de seus sentidos. Como aporte teórico, visitamos obras de autores consagrados tanto no âmbito da literatura infantil, quanto da temática da morte e da ilustração. Desses nomes, listamos Oliveira (2008), Abramovich (2008), Ramos e Nunes (2013), Paiva (2011), Lotterman (2009) e Aguiar (2010).

A Study on Humor Styles of Teacher Candidates
Authors: Aşılıoğlu Bayram
Published: February 2021

A teacher should have adaptive humor styles as well as knowledge, skills and attitudes about their profession. Humor styles affect many behaviors; from the relationships that teachers establish with their students to their characteristics. For this reason, this research was carried out to determine the humor styles of teacher candidates. 491 Teacher candidates have participated in this study, who were 3rd and 4th grade students in the faculty of education at 2 universities in Turkey. The researcher used the general survey model for the study. Data were collected using the Humor Styles Questionnaire (HSQ) developed by Martin et al. (2003). Findings showed that teacher candidates with the affiliative humor style had the highest average, those with the aggressive humor style had the lowest average. The averages of those with self-enhancing and self-defeating humor style were moderate. It was interpreted as positive that the average of those with self-enhancing humor style was high, as negative that the average of those with self-defeating humor style was moderate, and as positive the average of those with self-defeating humor style was low.
The Effect of Occupational Stress and Coping Strategies on Mental Health and Emotional Well-Being Among University Academic Staff During the COVID-19 Outbreak
Authors: Shen Panshuo , Slater Paul
Published: February 2021

The level of stress among academics in higher education institutions has significantly increased over the past decade. Mental health and well-being of academics can be affected once they are exposed to stressful work conditions and use negative coping strategies. This study was set against the backdrop of the pandemic disease, COVID-19, which has challenged the daily work of academics and risen to the various new stressors. This study aims to investigate the current status of occupational stress, coping styles, mental health and emotional well-being of university academics during the COVID-19 outbreak in Northern Ireland, and examine the effect of stress and coping strategies on mental health and emotional well-being. A cross-sectional online survey was conducted using a sample size of 87 academic staff working in a university in Northern Ireland. SPSS version 25 was used to analyse the collected data. The results showed academics experienced moderate stress levels, and distraction behaviours were the most common form of coping mechanism. Academics were in the moderate status of mental health and poor emotional well-being. Occupational stress has a significant effect on mental health and emotional well-being. Positive reframing and acceptance coping styles have an impact on emotional well-being. This study contributes to the understanding of occupational stress, coping strategies, mental health and emotional well-being of academics in higher education in Northern Ireland. The findings can help to develop reliable methods to inform policy on health and well-being for university academics, which in turn lead to increased productivity at work.

Published: February 2021

The research on the mechanical model of rubber spring is one of the hot spots in train dynamics. In order to accurately calculate the viscoelastic force of the rubber spring, especially the non-hyperelastic forces (NHEF) part, a NHEF model is proposed based on the elliptic approximation method. Furthermore, the calculation formula of periodic energy consumption is put forward. The NHEF model is verified by experiments, and the function λ isconstructed to verify the formula of periodic energy consumption. The calculation results showed that the NHEF model had high accuracy in predicting the dynamic and quasi-static NHEF of rubber spring, the prediction accuracy of shear condition was better than that of compression condition, and the accuracy of quasi-static condition was better than that of dynamic condition; the calculation formula of periodic energy consumption had a good prediction accuracy in all working conditions.

Authors: QIN Kai , LI Jingyuan , LIU Mengsha , JU Jinsan
Published: February 2021

The dynamic in-plane instability process of pin-ended arches under a central radial impact applied is analyzed with numerical simulation method. Based on energy characteristics of arch under impact, the method for determining the critical state of dynamic stability of both elastic arch and elastic–plastic arch under impact are discussed in this paper. The calculation results show that the strain energy of the elastic arch at dynamic stable critical state is consistent with that at a state after buckling under static load in which the bearing capacity of the arch drops to zero, and the difference between them are very small and no more than 3.6 %. When impact act on the arch with dynamic critical initial conditions, the converter efficiencies from initial kinetic energy possessed by the rigid body to elastic strain energy of arch approaches 100 %, therefore a feasible method is provided to determine the dynamic stability of elastic arch under impact on the energy method. Then the impact analysis of arch considering material nonlinearity is carried out, it is proposed that the instability of elastic-plastic arch can be judged by the forming of plastic hinges at about 1/4 on both sides of the arch. It is found that the elastic strain energy of elastic-plastic arch at dynamic stability critical state is very close to maximum elastic strain energy of the arch under static load, and the differences between them are no more than 3 %.

Published: February 2021

A high-speed centrifugal air compressor structure supported by aerodynamic pressure bearings and driven by a permanent magnet synchronous motor was proposed. The integration of air lubrication and permanent magnet synchronous motor is realized, which meets the fuel cell system's requirements for oil-free and efficient. Based on the analysis of the principle of aerodynamic pressure bearing and high-speed motor, the parameters of each component were designed, and the prototype of the air compressor was developed. When working at 10×104rpm, it can provide compressed air with a maximum pressure ratio of 2.3, and the overall efficiency is close to 80%, which achieves high-speed and stable operation, has higher efficiency and wider and flat working characteristics. Finally, the feasibility of the design was verified by bench test.

Published: February 2021

Background: The non-pharmacological interventions for behavioral problems of adolescents diagnosed with attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) are of great interest to researchers. Objectives: This study aimed to examine the efficacy of group reality therapy in behavioral symptoms in ADHD and ODD. Methods: Forty patients diagnosed with ADHD and ODD between 12 and 18 years were randomly assigned to two groups. The patients in the intervention group were participated in group reality therapy for five 120-minute sessions, once a week. The patients in the control group were enrolled in five unstructured sessions without intervention. Conners Parent Short Form questionnaire, Strengths and Difficulties Questionnaire (SDQ), and depression, anxiety, and stress scale (DASS-21) were performed at baseline, the sixth week, and the tenth week for follow-up. Results: Conners test showed a statistically significant difference in the intervention group in hyperactivity (P = 0.005), conduct (P < 0.001), and total score (P < 0.001) in the sixth week, as well as in conduct (P = 0.001), and total score (P = 0.008) in the tenth week. SDQ test analyzed based on partial Eta squared test, indicated the effect size in the intervention group was 81% and in the control group was 27%. Moreover, the DASS test in the intervention group showed improvement in depression, anxiety, and stress scores (P < 0.001).

Published: February 2021

Background: COVID-19 patients with preexisting comorbidities are at increased risk of exacerbated symptoms. Objectives: The current study aimed to firstly assess the impact of predisposed comorbidities on the severity of COVID-19, and secondly investigating the associated clinical outcome of patients with COVID-19 infection in Bangladesh. Methods: In this single-center retrospective study, the medical data of 157 hospitalized COVID-19 patients, including their preexisting comorbidities, from April 30, 2020, to June 15, 2020, are analyzed. Patients’ clinical outcomes in moderate-to-critical COVID-19 infections need for Intensive Care Unit (ICU) and mechanical ventilation support, and mortality were evaluated, with emphasis on predisposed chronic diseases. Results: Approximately 40.1 and 7.6% of patients (n = 157) presented severe and critical COVID-19 symptoms, respectively (P = 0.001). The most common comorbidity was diabeties (24.8%), followed by hypertension (23.2). Patients with one or two comorbidities did not present critical symptoms. Most of the critical cases had at least five comorbidities compared to those with 3 or 4 comorbidities (33.3% versus 8.3%; P = 0.038). The highest incidence of critical COVID-19 (41.7%) was among those with 7 comorbidities. Compared to patients with 4 or fewer comorbidities, patients with 5 (n = 15), 6 (n = 4), and 7 (n = 7) comorbidities were more hospitalized at ICU (above 70%, P = 0.025) and had a higher need for intubation support (above 60%, P = 0.038), and presented higher 30-day mortality (6.7, 25, and 28.6%, respectively; P = 0.002), which can be attributed to the declined clinical outcome of patients with 5 or more comorbidities in moderate-to-critical COVID-19 infection. Conclusions: This study demonstrated a positive association between the severity of COVID-19 and the number of predisposed comorbidities, which leads to poor clinical outcomes.

Published: February 2021

The systematics and distribution of the order Polycladida within the Macaronesian archipelagos are analysed. New species (Marcusia alba sp. nov., Prostheceraeus crisostomum sp. nov., Parviplana sodade sp. nov., Euplana claridade sp. nov., Stylochus salis sp. nov. and Distylochus fundae sp. nov.), new variety (Pseudoceros rawlinsonae var. galaxy), new records and records of shared species among different archipelagos are studied to compare the marine flatworm biodiversity of each island. The complex of archipelagos known as Macaronesia (including Madeira, Selvagens Islands, Canary Islands, Azores and Cape Verde) share a volcanic origin and European political influence. The five archipelagos are located along the eastern coast of the Atlantic Ocean and are subject to similar trade winds, streams (like the Gulf Stream) and cold currents. The term Macaronesia has suffered several changes throughout the years and it still is a topic of discussion in present times. The new delimitation of Macaronesia is mainly based on systematic studies on the invertebrate fauna of the islands. The resulting analyses shed new light on the differences and similarities among these archipelagos. In addition, molecular analyses employing 28S nuclear gene sequences are compared to verify relationships among anatomically similar species of marine polyclads.

Published: February 2021

A finales del siglo XIX las relaciones sociales aún estaban marcadas por unos estrictos códigos que se debían cumplir de manera escrupulosa. Siguiendo rígidas normas de etiqueta, cualquier acción –desde peticiones de bailes a recibir o realizar visitas– se debía llevar a cabo de idéntica forma para encajar en el rígido marco moral de la época. Nada mejor que uno de los más eminentes miembros de la alta sociedad dejara por escrito cómo comportarse en los eventos sociales. Así fue como en 1883 aparecía la primera edición del Código o deberes de buena sociedad de Camilo Fabra, alcalde de Barcelona entre enero y abril de 1893 y marqués de Alella.

Migratismi di moda
Authors: Ferrari Jacopo
Published: February 2021

The lexicon of immigrant writers in Italy is full of words derived from their mother tongues. Among the semantic fields most involved is undoubtedly that of fashion. We find many clothes, dresses, fabrics typical of the areas of emigration to Italy: Arab world, states of sub-Saharan Africa, Middle East and Asia. Some of these are attested in Italian for a long time now (burnus, fez, sari); others are very recent, in correlation with migration and the presence of immigrant communities in Italy. The term ‘migratismo’ has been proposed for this class of words. Some ‘migratismi’ have already spread in Italian and recorded in vocabularies (for example the veils of Islamic women: burqa, hijab, niqab). Their circulation has produced derived and compound words (burkini, antiburqa). Others are well detectable in the italian literature of migration, where the authors explain the meaning with a gloss or in a note. Searches in archives and databases allow to understand the real circulation of these words.
Robust adaptive PD-like control of lower limb rehabilitation robot based on human movement data
Authors: Hu Ningning , Wang Aihui , Wu Yuanhang
Published: February 2021

The combination of biomedical engineering and robotics engineering brings hope of rehabilitation to patients with lower limb movement disorders caused by diseases of the central nervous system. For the comfort during passive training, anti-interference and the convergence speed of tracking the desired trajectory, this paper analyzes human body movement mechanism and proposes a robust adaptive PD-like control of the lower limb exoskeleton robot based on healthy human gait data. In the case of bounded error perturbation, MATLAB simulation verifies that the proposed method can ensure the global stability by introducing an S-curve function to make the design robust adaptive PD-like control. This control strategy allows the lower limb rehabilitation robot to track the human gait trajectory obtained through the motion capture system more quickly, and avoids excessive initial output torque. Finally, the angle similarity function is used to objectively evaluate the human body for wearing the robot comfortably.
Characteristics of planktonic and sediment bacterial communities in a heavily polluted urban river

Published: February 2021

Urban rivers represent a unique ecosystem in which pollution occurs regularly, altering the biogeochemical characteristics of waterbodies and sediments. However, little is presently known about the spatiotemporal patterns of planktonic and sediment bacterial community diversities and compositions in urban rivers. Herein, Illumina MiSeq high-throughput sequencing was performed to reveal the spatiotemporal dynamics of bacterial populations in Liangtan River, a heavily polluted urban river in Chongqing City (China). The results showed the richness and diversity of sediment bacteria were significantly higher than those of planktonic bacteria, whereas a strong overlap (46.7%) in OTUs was identified between water and sediment samples. Bacterial community composition remarkably differed in waters and sediments. Planktonic bacterial communities were dominated by Proteobacteria, Bacteroidetes, Cyanobacteria and Actinobacteria, while sediment bacterial communities mainly included Proteobacteria, Actinobacteria, Chloroflexi and Bacteroidetes. Additionally, several taxonomic groups of potential bacterial pathogens showed an increasing trend in water and sediment samples from residential and industrial areas (RI). Variation partition analysis (VPA) indicated that temperature and nutrient were identified as the main drivers determining the planktonic and sediment bacterial assemblages. These results highlight that bacterial communities in the polluted urban river exhibit spatiotemporal variation due to the combined influence of environmental factors associated with sewage discharge and hydropower dams.
A new kentriodontid (Cetacea: Odontoceti) from the early to middle Miocene of the western North Pacific and a revision of kentriodontid phylogeny
Authors: Guo Zixuan , Kohno Naoki
Published: February 2021

A new species of an extinct dolphin belonging to the kentriodontids, i.e.,Kentriodon sugawaraisp. nov., is described from the upper lower to lowest middle Miocene Kadonosawa Formation in Ninohe City, Iwate Prefecture, northern Japan. The holotype ofKentriodon sugawaraisp. nov., consists of a partial skull with ear bones, mandibular fragments, and some postcranial bones. This new species shares five unique characters with other species ofKentriodon. In addition, the new species differs from other species of the genus in displaying a narrow width of the squamosal lateral to the exoccipital in posterior view, the dorsolateral edge of the opening of the ventral infraorbital foramen that is formed by the maxilla and the lacrimal or the jugal, and at least three anterior dorsal infraorbital foramina. Our phylogenetic analysis based on 393 characters for 103 Odontoceti taxa yielded a consensus tree showing all previously identified kentriodontids as a monophyletic group that comprises the sister group of the crown Dephinoidea, which in turn include Delphinidae, Phocoenidae and Monodontidae. Our analysis also indicates that the distinct innovation of the acoustic apparatus (i.e., 13 out of 29 derived characters are from tympanoperiotic) would have occurred in the ancestral lineage of the Delphinoidea (sensu lato) including the monophyletic Kentriodontidae during their initial evolution and diversification.
Using UAV‐mounted thermal cameras to detect the presence of nesting nightjar in upland clear‐fell: A case study in South Wales, UK

1. Confirming the presence and location of European Nightjar Caprimulgus europaeus nests is a significant fieldwork challenge in ecological monitoring. Nest sites can be located through direct observation or capture and radio tracking of breeding individuals; however, such work is time consuming, disturbing and costly.

2. Unmanned aerial vehicles (UAV) equipped with thermal sensors may enable rapid survey over large areas by detecting nest locations based on the contrast of relatively warm nests and the surrounding cooler ground. The application of this concept using UAV‐mounted thermal sensors was trialled in two upland clear‐fell forestry sites in South Wales, UK.

3. Detection trials were undertaken at five known nightjar nest sites to assess optimal timing and flight height for surveys. Nest heat signatures were clear during dusk and dawn, but not during the daytime. Nests were identifiable at flight heights up to 25 m, but flight heights of 12–20 m were optimal for the numbers of pixels per nest.

4. This approach was tested in a field trial of a 17‐ha forestry site where the presence and position of nesting nightjars were unknown. An automated transect at dusk and dawn at 15 m flight elevation identified two active nightjar nests and four male nightjar roost sites. Without image analysis automation, the process of manual inspection of 2607 images for ‘hotspots’ of the approximate size and shape of nightjar nests was laborious.

5. The UAV approach took around 18 h including survey time, processing and ground verification, whilst a nightjar nest finding survey would take 35 h for the same area. The small size of nightjars and the low resolution of the thermal sensors requires low altitude flight in order to maximize detectability and pixel coverage. Low flight elevation requires more consideration of the risk of collision with trees or posts. Consequently, the approach would not be suitable for covering areas of highly variable terrain.

Purpose

To compare two inverse planning algorithms, the hybrid inverse planning optimization (HIPO) algorithm and the inverse planning simulated annealing (IPSA) algorithm, for cervical cancer brachytherapy and provide suggestions for their usage.

Material and methods

This study consisted of 24 cervical cancer patients treated with CT image‐based high‐dose‐rate brachytherapy using various combinations of tandem/ovoid applicator and interstitial needles. For fixed catheter configurations, plans were retrospectively optimized with two methods: IPSA and HIPO. The dosimetric parameters with respect to target coverage, localization of high dose volume (LHDV), conformal index (COIN), and sparing of organs at risk (OARs) were evaluated. A plan assessment method which combines a graphical analysis and a scoring index was used to compare the quality of two plans for each case. The characteristics of dwell time distributions of the two plans were also analyzed in detail.

Results

Both IPSA and HIPO can produce clinically acceptable treatment plans. The rectum D2cc was slightly lower for HIPO as compared to IPSA (P = 0.002). All other dosimetric parameters for targets and OARs were not significantly different between the two algorithms. The generated radar plots and scores intuitively presented the plan properties and enabled to reflect the clinical priorities for the treatment plans. Significant different characteristics were observed between the dwell time distributions generated by IPSA and HIPO.

Conclusions

Both algorithms could generate high‐quality treatment plans, but their performances were slightly different in terms of each specific patient. The clinical decision on the optimal plan for each patient can be made quickly and consistently with the help of the plan assessment method. Besides, the characteristics of dwell time distribution were suggested to be taken into account during plan selection. Compared to IPSA, the dwell time distributions generated by HIPO may be closer to clinical preference.

Objective

No relapse risk prediction tool is currently available to guide treatment selection for multiple sclerosis (MS). Leveraging electronic health record (EHR) data readily available at the point of care, we developed a clinical tool for predicting MS relapse risk.

Methods

Using data from a clinic‐based research registry and linked EHR system between 2006 and 2016, we developed models predicting relapse events from the registry in a training set (n = 1435) and tested the model performance in an independent validation set of MS patients (n = 186). This iterative process identified prior 1‐year relapse history as a key predictor of future relapse but ascertaining relapse history through the labor‐intensive chart review is impractical. We pursued two‐stage algorithm development: (1) L1‐regularized logistic regression (LASSO) to phenotype past 1‐year relapse status from contemporaneous EHR data, (2) LASSO to predict future 1‐year relapse risk using imputed prior 1‐year relapse status and other algorithm‐selected features.

Results

The final model, comprising age, disease duration, and imputed prior 1‐year relapse history, achieved a predictive AUC and F score of 0.707 and 0.307, respectively. The performance was significantly better than the baseline model (age, sex, race/ethnicity, and disease duration) and noninferior to a model containing actual prior 1‐year relapse history. The predicted risk probability declined with disease duration and age.

Conclusion

Our novel machine‐learning algorithm predicts 1‐year MS relapse with accuracy comparable to other clinical prediction tools and has applicability at the point of care. This EHR‐based two‐stage approach of outcome prediction may have application to neurological disease beyond MS.

Developing novel solid additives has been regarded as a promising strategy to achieve highly efficient organic solar cells with good stability and reproducibility. Herein, a small molecule, 2,2′‐(perfluoro‐1,4‐phenylene)dithiophene (DTBF), designed with high volatility and a strong quadrupole moment, is applied as a solid additive to implement active layer morphology control in organic solar cells. Systematic theory simulations have revealed the charge distribution of DTBF and its analog and their non‐covalent interaction with the active layer materials. Benefitting from the more vital charge–quadrupole interaction, the introduction, and volatilization of DTBF effectively induced more regular and condensed molecular packing in the active layer, leading to enhanced photoelectric properties. Thus, high efficiency of over 17% is obtained in the DTBF‐processed devices, which is higher than that of the control devices. Further application of DTBF in different active layer systems contributed to a deeper comprehension of this type of additive. This study highlights a facile approach to optimizing the active layer morphology by finely manipulating the quadrupole moment of volatile solid additives.

Metallic lithium anode has long stood as the “holy grail” in the field of secondary batteries for its high theoretical specific capacity and low electrochemical potential. But its edge is blunted by the inherent uncontrolled lithium dendrite growth that can curtail the cycle life and raise safety concerns. In this work, a functional modification layer from a derivant of natural silk is developed to protect lithium anode via a facile automatic transfer route. Via offering abundant functional group sites, the Li‐ion flux on the anode surface is made uniform efficiently. The silk fibroin‐based modification layer also contributes to the in situ formation of a Li3N‐rich solid electrolyte interphase film on the lithium anode. Consequently, a high‐performance lithium metal anode with dendrite‐free morphology and significantly enhanced cycle stability is achieved: when paired with LiFePO4 cathodes, the full cell achieves a long‐term cycling stability of 3000 cycles at 5 C; when paired with sulfur cathodes (5 mgsulfur cm−2), a long lifespan for over 400 cycles at 1 C is achieved. This work offers a facile and practical approach for the interface modification of the high‐performance lithium anode and as well as provides a new perspective for the application of biomass‐based materials in advanced batteries.

Infrared (IR) adaptation phenomena are ubiquitous in nature and biological systems. Taking inspiration from natural creatures, researchers have devoted extensive efforts for developing advanced IR adaptive materials and exploring their applications in areas of smart camouflage, thermal energy management, biomedical science, and many other IR‐related technological fields. Herein, an up‐to‐date review is provided on the recent advancements of bioinspired IR adaptive materials and their promising applications. First an overview of IR adaptation in nature and advanced artificial IR technologies is presented. Recent endeavors are then introduced toward developing bioinspired adaptive materials for IR camouflage and IR radiative cooling. According to the Stefan‐Boltzmann law, IR camouflage can be realized by either emissivity engineering or thermal cloaks. IR radiative cooling can maximize the thermal radiation of an object through an IR atmospheric transparency window, and thus holds great potential for use in energy‐efficient green buildings and smart personal thermal management systems. Recent advances in bioinspired adaptive materials for emerging near‐IR (NIR) applications are also discussed, including NIR‐triggered biological technologies, NIR light‐fueled soft robotics, and NIR light‐driven supramolecular nanosystems. This review concludes with a perspective on the challenges and opportunities for the future development of bioinspired IR adaptive materials.
PRMT5 Enables Robust STAT3 Activation via Arginine Symmetric Dimethylation of SMAD7

Published: February 2021

Protein arginine methyltransferase 5 (PRMT5) is the type II arginine methyltransferase that catalyzes the mono‐ and symmetrical dimethylation of protein substrates at the arginine residues. Emerging evidence reveals that PRMT5 is involved in the regulation of tumor cell proliferation and cancer development. However, the exact role of PRMT5 in human lung cancer cell proliferation and the underlying molecular mechanism remain largely elusive. Here, it is shown that PRMT5 promotes lung cancer cell proliferation through the Smad7‐STAT3 axis. Depletion or inhibition of PRMT5 dramatically dampens STAT3 activation and thus suppresses the proliferation of human lung cancer cells. Furthermore, depletion of Smad7 blocks PRMT5‐mediated STAT3 activation. Mechanistically, PRMT5 binds to and methylates Smad7 on Arg‐57, enhances Smad7 binding to IL‐6 co‐receptor gp130, and consequently ensures robust STAT3 activation. The findings position PRMT5 as a critical regulator of STAT3 activation, and suggest it as a potential therapeutic target for the treatment of human lung cancer.
