Authors: Costa-Silva Vinícius , Carvalho Edrielly , Vaz-de-Mello Fernando Z. 
Published: March 2022

Differential diagnoses, updates on distribution ranges, and an illustrated identification key are given for all species of Agamopus. The first record for A. castaneus from Brazil is given. Type specimens of all valid species-group names are studied and illustrated. Notes on the natural history of Agamopus species, as well as brief phylogenetic comments, are presented. The new species Agamopus joker sp. nov. is described based on a male from Paraná, southern Brazil. Lectotypes are designated for Canthon unguicularis Harold, 1883 and Agamopus lampros Bates, 1887. We also propose the transfer of Agamopus convexus Balthasar, 1965 to the Ateuchus ovalis species group (Ateuchus convexus comb. nov.) based on morphological features of the protibiae, clypeal teeth, and the posterior margin of the pronotum and pygidium.

Published: March 2022

Na busca de vantagem competitiva, as empresas provocam mudanças em seus produtos e serviços por meio de ações que ofereçam algum incremento e que estes sejam percebidos pelos clientes, entretanto, essas ações – quando realizadas – são ocasionais e de baixo impacto, fazendo com que nem o cliente, nem o empreendedor percebam os possíveis benefícios. Além disso, dado o possível fracasso nestas ações, o esforço, o tempo e os custos envolvidos acabam desmotivando o empreendedor e gerando uma cultura avessa á inovação, assim, nota-se baixa intenção em investir e promover uma cultura de inovação. Diante desse quadro, o objetivo deste artigo consiste em compreender como promover a cultura da inovação nas micro e pequenas empresas, descrevendo conceitos, tipologia, características e aplicações que buscam compreender como ela ocorre no contexto e ambiente empresarial. Para elaboração deste estudo foram realizadas pesquisas bibliográficas e documentais que mostram os fatores críticos que evidenciam a implementação da cultura da inovação, além de um exemplo prático de aplicação contemplado no programa Agentes Locais de Inovação (ALI) desenvolvido pelo SEBRAE. O método de pesquisa adotado foi exploratório. Este estudo tem por objetivo oferecer aos leitores um novo olhar acerca da prática da inovação, identificando possibilidades de melhoria, gerando novas oportunidades de negócio.

Published: March 2022

Background: Ballet dancers are exposed to high rates of foot and ankle injury. Nevertheless, there have been limited efforts to capture their perspectives regarding risk of injury, treatment compliance, and prevention. The purpose of this study was to portray the perspectives of ballet dancers collected through organized focus group discussions.
Methods: Seven focus group sessions were conducted, with 47 ballet dancers participating. The conversation was directed to consider a variety of factors related to injury, both direct and remote. Transcripts from these focus groups were coded into ten major themes: internal pressure, external pressure, ballet milestones, seeking treatment, treatment compliance, targeted treatment, return to dance, nondance activities, physical fatigue, and activity preparation.
Results: It was found that participants returned to dancing prematurely after injury, faced significant internal and external pressure, lacked adherence to suggested treatment, and identified provider communication as lacking.
Conclusions: The results of this study can help with efforts to reduce injuries, encourage treatment compliance, and improve injury prevention. Future studies might consider the effectiveness of specific interventional approaches.

Background: Fungal foot infection is a common superficial fungal infection and is recognized as an important public health problem. Related to the wearing of occlusive footwear, foot infection is usually caused by dermatophytes and nondermatophyte molds. Previous in vitro studies have demonstrated that zinc oxide nanoparticles (ZnO-NPs) have antimicrobial activity against fungi. This study, therefore, evaluated the ability of socks coated with ZnO-NPs to inhibit fungal growth in an in vitro model mimicking real-life situations.
Methods: Scale from patients with fungal foot infections was equally divided into three groups: control, plain socks, and ZnO-NP socks. The specimens in the control group were routinely fungal cultured, whereas in the plain sock and ZnO-NP sock groups, scale was incubated with plain socks and ZnO-NP socks, respectively, for 24 hours. After incubation, each piece of sock was cultured. The fungal culture results of the three groups were progressively evaluated for 4 weeks.
Results: From 31 specimens, the positive fungal culture results of the control, plain sock, and ZnO-NP sock groups were 100%, 64.5%, and 54.8%, respectively. Specimens incubated with plain socks (P = .001) or with ZnO-NP socks (P < .001) had a significant reduction in the number of positive fungal cultures compared with the control.
Conclusions: Plain socks and ZnO-NP socks significantly inhibited fungal growth relative to the control. The wearing of either plain socks or ZnO-NP socks can prevent fungal foot infection because these socks act as a barrier to the insoles of shoes.

Authors: Perez-Gurbindo Ignacio , Peñaranda Yolanda Fuentes , García Ángel Orejana , Alvarez-Mendez Ana 
Published: March 2022

Background: The evaluation of musculoskeletal pain in podiatric medical practice is mainly based on anamnesis and manual examination. However, when manual palpation is performed, the digital pressure necessary to adequately explore the different structures of the foot is unknown. We evaluated the pressure pain threshold in forefoot structures to determine the intensity and duration of the stimulus as clinically relevant and representative.
Methods: In a transversal analytical study of 15 healthy individuals, 16 forefoot points were explored with a handheld pressure palpometer calibrated to exert maximum pressing force of 1.0 or 2.0 kilogram-force (kgf) applied during 5 or 10 sec. The combinations of the different pressures and intervals were selected randomly. Participants had to self-rate the pressure pain sensitivity of each stimuli on a 100-mm horizontal line (0–100 numeric rating scale), setting the pain threshold to 50 (100 being pain as bad as it could be). Likewise, aftersensation and referred pain patterns were recorded.
Results: All participants indicated painful stimuli at some of the 16 forefoot points studied in the experimental protocol when pressure was applied with the 2.0-kgf palpometer; 53.3% showed evidence of pain at any forefoot point when the 1.0-kgf palpometer was used. The odds of evoking a painful sensation are 9.8 times higher when using a 2.0-kgf palpometer versus a 1.0-kgf palpometer. In addition, referred sensations were observed with a significantly higher frequency when applying the 2.0-kgf palpometer.
Conclusions: Bone and soft structures show differences in pressure sensitivity, increasing significantly when applying higher pressure force. Soft structures, specifically intermetatarsal spaces, showed the lowest pain pressure thresholds. More research is needed to better understand pressure pain response.
Evaluation of Glycologic Point-of-Care Infection Test Kit for Diabetic Foot Ulcers in Relation to Bacterial Presence: A Prospective Cohort Study

Published: March 2022

Background: Point-of-care testing for infection might help podiatric physicians optimize management of diabetic foot ulcers (DFUs). Glycologic’s proprietary GLYWD product has been developed to detect changes in a patient’s immunologic/inflammatory response related to wound infection. We evaluated how bacterial presence in DFUs relates to GLYWD test outcome.
Methods: This was a single-organization, prospective, controlled cohort study of clinical opinion versus GLYWD test result for DFU infection status and the appraisal of bacterial presence in the wounds and semiquantitative microbiology swab at weeks 0, 3, 6, 12, and 18. Spearman correlation, backward elimination linear regression, and principal components analysis were applied to determine which variables, including degree of bacterial load, are associated with a positive clinical opinion or GLYWD result for DFU infection.
Results: Forty-eight patients were enrolled, and 142 complete wound appraisals were conducted; a consensus outcome between clinical opinion and GLYWD result was achieved in most (n = 122, 86%). Clinical opinion significantly correlated with a higher bacterial load (Spearman rho = 0.38; P < .01), whereas GLYWD did not (rho = –0.010; P = .91). This observation was corroborated with logistic regression analysis, in which a previous observation of both clinical opinion and GLYWD associating with wound purulence and erythema was also confirmed.
Conclusions: Podiatric physicians are guided by hallmark signs of DFU infection, such as erythema and purulence; furthermore, we found that clinical opinion of infection correlates with increased bacterial load. GLYWD test results match clinical opinion in most cases, although the results obtained with this point-of-care method suggest that the degree of bacterial presence might not necessarily mean a higher chance of inducing an immunologic/inflammatory host response to said bacteria.
Beyond Coding
Authors: Bers Marina Umaschi 
Published: March 2022

Why children should be taught coding not as a technical skill but as a new literacy—a way to express themselves and engage with the world.
Today, schools are introducing STEM education and robotics to children in ever-lower grades. In Beyond Coding, Marina Umaschi Bers lays out a pedagogical roadmap for teaching code that encompasses the cultivation of character along with technical knowledge and skills. Presenting code as a universal language, she shows how children discover new ways of thinking, relating, and behaving through creative coding activities. Today's children will undoubtedly have the technical knowledge to change the world. But cultivating strength of character, socioeconomic maturity, and a moral compass alongside that knowledge, says Bers, is crucial.
Bers, a leading proponent of teaching computational thinking and coding as early as preschool and kindergarten, presents examples of children and teachers using the Scratch Jr. and Kibo robotics platforms to make explicit some of the positive values implicit in the process of learning computer science. If we are to do right by our children, our approach to coding must incorporate the elements of a moral education: the use of narrative to explore identity and values, the development of logical thinking to think critically and solve technical and ethical problems, and experiences in the community to enable personal relationships. Through learning the language of programming, says Bers, it is possible for diverse cultural and religious groups to find points of connection, put assumptions and stereotypes behind them, and work together toward a common goal.

Published: March 2022

AbstractLayered 2D van der Waals semiconductors and their heterostructures have been shown to exhibit positive photoconductance (PPC) in many studies. A few recent reports have demonstrated negative photoconductance (NPC) as well that can enable broadband photodetection besides multi‐level optoelectronic logic and memory. Controllable and reversible switching between PPC and NPC is a key requirement for these applications. This report demonstrates visible‐to‐near infrared wavelength‐driven NPC and PPC, along with reversible switching between the two, in an air stable, high mobility, broadband black phosphorus field effect transistor covered with a few layer MoS2 flake. The crossover switching wavelength can be tuned by varying the MoS2 bandgap through its flake thickness and the NPC and PPC photoresponsivities can be modulated using electrostatic gating as well as laser power. Recombination‐driven NPC and PPC, as supported by density functional theory calculations, allows for reversible switching. Further, gate voltage‐dependent negative persistent photoconductance is well‐suited for optosynaptic applications.

AbstractLead‐free Cs2AgBiBr6 double perovskite has received widespread attention because of its non‐toxicity and high thermal stability. However, intrinsic bromide ion (Br–) migration limits continuous operation of Cs2AgBiBr6‐based perovskite solar cells (PSCs). Herein, an operational and simple strategy is carried out to improve the power conversion efficiency (PCE) and long‐term stability of Cs2AgBiBr6‐based PSCs by introducing 1‐butyl‐1‐methylpyrrolidinium chloride (BMPyrCl) and 1‐butyl‐3‐methylpyridinium chloride (BMPyCl) ionic liquids (ILs). The higher binding energy between Br– in Cs2AgBiBr6 and cation in IL containing pyrrole can inhibit Br– migration effectively, thereby reducing film defects and improving energy level matching. The optimized PCE of 2.22% is obtained for hole transport layer‐free, carbon‐based PSC, which hardly degrades at 40% ± 5% relative humidity and 25 °C for 40 days. This work highlights an effective method to mitigate the halide migration in Cs2AgBiBr6 perovskite, thus providing an effective route in promoting the development of lead‐free double PSCs.
3D Architecturing Strategy on the Utmost Carbon Nanotube Fiber for Ultra‐High Performance Fiber‐Shaped Supercapacitor

Published: March 2022

AbstractFiber‐shaped supercapacitors (FSSCs) are the most state‐of‐the‐art power supplies suitable for wearable devices, but the intrinsically limited cylindrical space of fibers restricts their high electrochemical performance, which must be overcome with a delicate and systematic architectural process. Here, a simple but effective 3D architectural strategy for fabricating FSSCs with high performance and flexibility is proposed. Highly conductive liquid crystal spun carbon nanotube fiber (CNTF) is an excellent 1D core fiber for the electrophoretic deposition of graphene oxide (GO). The deposited GO forms a vertical 3D structure on the CNTF (VG@CNTF), which can be successfully preserved by a consecutive coating of pseudocapacitive active materials onto the surface of VG. Notably, a solid‐state asymmetric FSSC shows an outstanding performance of 65 Wh kg−1 at 100 kW kg−1 and exceptional stability and flexibility (capacitance retention of 98.60% at bending angles of 90° and 93.1% after 5000 bending cycles). This work can provide new insight into the development of high‐performance FSSCs for practical wearable applications.

AbstractSelectivity for specific analytes and high‐temperature operation are key challenges for chemiresistive‐type gas sensors. Complementary hybrid materials, such as reduced graphene oxide (rGO) decorated with metal oxides enables realization of room‐temperature sensors with enhanced sensitivity. However, sensor training to identify target gases and accurate concentration measurement from gas mixtures still remain very challenging. This work proposes hybridization of rGO with CuCoOx binary metal oxide as a sensing material. Highly stable, room‐temperature NO2 sensors with a 50 ppb of detection limit is demonstrated using inkjet printing. A framework is then developed for machine‐intelligent recognition with good visibility to identify specific gases and predict concentration under an interfering atmosphere from a single sensor. Using ten unique parameters extracted from the sensor response, the machine learning‐based classifier provides a decision boundary with 98.1% accuracy, and is able to correctly predict previously unseen NO2 and humidity concentrations in an interfering environment. This approach enables implementation of an intelligent platform for printable, room‐temperature gas sensors in a mixed environment irrespective of ambient humidity.

Published: March 2022

AbstractA high‐throughput computational framework to identify novel multinary perovskite redox mediators is presented, and this framework is applied to discover the Gd‐containing perovskite oxide compositions Gd2BB′O6, GdA′B2O6, and GdA′BB′O6 that split water. The computational scheme uses a sequence of empirical approaches to evaluate the stabilities, electronic properties, and oxygen vacancy thermodynamics of these materials, including contributions to the enthalpies and entropies of reduction, ΔHTR and ΔSTR. This scheme uses the machine‐learned descriptor τ to identify compositions that are likely stable as perovskites, the bond valence method to estimate the magnitude and phase of BO6 octahedral tilting and provide accurate initial estimates of perovskite geometries, and density functional theory including magnetic‐ and defect‐sampling to predict STCH‐relevant properties. Eighty‐three promising STCH candidate perovskite oxides down‐selected from 4392 Gd‐containing compositions are reported, three of which are referred to experimental collaborators for characterization and exhibit STCH activity. The results demonstrate that the high‐throughput computational scheme described herein—which is used to evaluate Gd‐containing compositions but can be applied to any multinary perovskite oxide compositional space(s) of interest—accelerates the discovery of novel STCH active redox mediators with reasonable computational expense.

AbstractPoor rate capability is a significant obstacle for the practical application of inorganic all‐solid‐state lithium‐ion batteries (ASSLIBs). The charge transfer kinetics at the interface of current collectors is crucial for high‐rate capacity, but is typically neglected. In this paper, the interfacial evolution between Al foil current collectors and composite cathodes is studied in the LiCoO2/Li3InCl6 (LCO/LIC) ASSLIBs at both 25 and −10 °C. The results indicate that the side reactions between Al foil and LIC are the main challenges for the interfacial stability of current collector at 25 °C. The design of a graphene‐like carbon (GLC) coating for the modification of Al avoids side reactions at the interface of current collector, resulting in improved cycling stability and high‐rate capacity. GLC Al ASSLIB exhibits a high initial capacity of 102.9 mAh g–1 with a capacity retention of 89.1% after 150 cycles at 1 C. A high‐rate capacity of 69 mAh g–1 is also achieved at 5 C. At −10 °C, the low Li+/electron transfer kinetics along with side reactions is the key limitation for the rate capability. Thanks to the GLC coating, the improved electrochemical performance is achieved with the enhanced charge transfer kinetics at the interface of current collector.

AbstractAmorphous calcium carbonate (ACC) is a common precursor to crystalline calcium carbonate, and is of particular importance in biomineralization, where its crystallization in privileged environments ensures a pseudomorphic transformation. While organisms regulate this process using organic molecules and magnesium ions to selectively form calcite or aragonite, it has proven highly challenging to replicate this polymorph selectivity synthetically. Here, it is demonstrated that remarkable control can be achieved over the chemical composition and structure of crystalline calcium carbonate by using heat to drive a pseudomorphic transformation of ACC thin films. The crystal polymorph can be tuned from low magnesium‐calcite to pure aragonite, high magnesium‐calcite, and ultimately dolomite according to the magnesium content of the ACC, and mosaics of large single crystals are generated at elevated temperatures rather than the spherulitic structures formed at room temperature. This methodology also enables an in situ investigation of the ACC crystallization mechanism using transmission electron microscopy. Finally, the approach can be combined with templating methods to generate arrays of large aragonite single crystals with preselected morphologies. These results demonstrate that exceptional control can be achieved through the solid‐state transformation of Mg‐ACC, which has relevance to both synthetic and biological systems.
