The Emergence of Collective Leadership During a Terrorist Attack: Dynamic Role Boundary Transgressions as Central in Aligning Efforts

The current article examines the emergence and dynamics of leadership during an extreme situation—a terrorist attack at the foreign subsidiary of a multinational energy corporation—and the crisis response undertaken at the corporate headquarters. The inductive analysis reveals that the in-situ crisis leadership involved impromptu interactions between multiple individuals leading collectively. Multiple sources of leadership emerged to carry out four critical leadership functions, namely strategic framing, ad hoc structuring, relational coping, and instant developing. These functions were carried out by several formal and informal leaders together, enhancing the overall leadership capacity in the crisis management organization (CMO). With increased capacity to lead efforts in different domains came specialization, which could have led to misalignment and fragmentation. But this was avoided by leaders acting as “role boundary transgressors,” expanding the boundaries of their responsibilities across roles, functions, and levels to foster the alignment of collective efforts across the CMO. Based on rich data from a leadership situation that researchers rarely have access to, this study contributes to the understanding of leadership during extreme situations by illustrating who leads (the emergence of multiple leadership sources), what leaders do (leadership functions), and how leadership plays out over time and across levels (through dynamic role boundary transgressions).
Foraging Behaviour of Some Syrphid Flies on Mango

This study in on the foraging behaviour of syrphid flies belonging to the tribes Eristalini (Eristalinus arvorum, E. quinquestriatus and Mesembrius quadrivittatus) and Syrphini (Episyrphus balteatus). The foraging activity, rate and speed, loose pollen grains and abundance were evaluated at Jorhat during 2018 and 2019 on mango flowers var. Amrapali. These revealed that the peak period of visit was 1 000-1200 hr. The relative abundance of the syrphids was maximum (8.90 ± 0.22/5 min) at 1100-1200 hr and (7.07 ± 0.51/5 min) at 1200-1300 hr; it was minimum (2.40 ± 0.17 and 2.49 ± 0.09/5min) at 0700-0800 hr, respectively. The loose pollen grains adhering to them ranged from 1294.80 ± 60.82 to 1415.80 ± 110.80/forager. The maximum pollination index of 12.52 was obtained with the Eristalini, while it was 8.14 in Syrphini (2018); in 2019, it was 9.63 and 7.14, respectively. These syrphids visited flowers during midday with more activity, foraging rate and foraging speed.
COVID-19 Lockdown in New Zealand: Perceived Stress and Wellbeing among International Health Students Who Were Essential Frontline Workers

This study examined the stresses and wellbeing of international postgraduate health and nursing students at a tertiary education institute in New Zealand who were mainly essential frontline healthcare workers during the COVID-19 lockdown. Quantitative and qualitative data were collected by purposeful sampling (n = 43). The study utilised a cross-sectional survey, along with the Short Form of Cohen’s Perceived Stress Scale (PSS-10), adapted for the COVID-19 lockdown, and followed by semi-structured individual interviews. This study is the first in New Zealand to demonstrate that, with a mean PSS-10 score of 21.7 (±7.1), international health students experienced higher than optimal levels of stress, with supporting qualitative data identifying four themes for the sources of stress: (1) familial relationships, (2) essential work, (3) finances, and (4) study. However, these students coped because of the extensive support provided by their education institute and employers. These students played a critical role in the pandemic’s response and made a significant public health contribution by working in the frontline of the COVID-19 outbreak. Considering the global shortage of healthcare workers and understanding the key challenges, means of coping and support provisions, as we have here, offer insights for building and maintaining a resilient and resourceful health workforce through international health and nursing students in New Zealand and elsewhere.
Diabetic foot disease during the COVID-19 pandemic: lessons learned for our future

The COVID-19 pandemic has had a strong impact on the treatment of all diseases, especially chronic ones, and diabetic foot is no exception. The COVID-19 pandemic has favored the adoption of a new model of assistance delivery to facilitate the delivery of remote assistance to patients. The standard model based on face-to-face visits has been integrated by a hybrid model of telemedicine, home care and face-to-face visits to keep patients at home to minimize the number of in-person visits to clinics and admissions except for complicated DFUs. However, telemedicine is not always possible or suitable for various reasons (patients not digital, need for practical treatment of the foot etc.). In this review, we looked at the different approaches to diabetic foot ulcer management and the indirect impact of the COVID-19 pandemic on diabetes-related lower extremity complications and the lessons we have learned for the future.
Comparing strategies for improving efficiencies in vacuum processed Cu2ZnSnSe4 solar cells

In this study, we detail a Cu2ZnSnSe4 based solar cell fabrication process based on the selenization of metallic precursor stacks with elemental Se. 9.4% efficient devices without antireflection coating have been obtained. First, reproducibility issues of the process are carefully shown and discussed. It is demonstrated that device performances are strongly impacted by the precise control of the precursor composition. Then, starting from this robust process, a review of existing strategies to improve kesterite efficiencies is conducted. A significant increase in efficiency (+1.4% absolute efficiency and +50 mV VOC) is obtained with absorber surface treatment and post-annealing, while no effect of Ge incorporation in the precursor stack is observed. This contradictory result to most of the recent publications raises the question of the universality of this strategy to improve kesterite solar cell performance. Finding a universal activation step to boost kesterite efficiencies and bring it to the market remains a crucial need for the community.In this study, we detail a Cu2ZnSnSe4 based solar cell fabrication process based on the selenization of metallic precursor stacks with elemental Se. 9.4% efficient devices without antireflection coating have been obtained.

Spiking Neural Network With Weight-Sharing Synaptic Array for Multi-input Processing

A multi-input processing spiking neural network inference system (MSS) is proposed to enhance the parallel processing capabilities of the spiking neural network (SNN) inference relative to the conventional SNN inference. Processing multiple input samples using MSS with shared synaptic arrays for compute-in-memory drastically reduces the number of synaptic arrays assigned for parallel processing, thereby minimizing the effort required by parallel processing networks. A shared weight array is evaluated using the 4-bit quantization capabilities of a manufactured ferroelectric field-effect-transistor as a synaptic device. A batch action was implemented as a multi-input on a 3-layer fully connected network to verify the MSS. The benefits of MSS in energy consumption and area throughput are rigorously investigated and estimated based on the number of multi-input processing. It is proven that the simultaneously processing of multiple input samples using the proposed MSS boosts the energy and area efficiency by up to 9.12 and 242 times, respectively.
Shape Deblurring with Unsharp Masking Applied to Mesh Normals

Unsharp masking is a well-known image sharpening technique. Given an image and its smoothed version, amplifying high frequencies of the image via unsharp masking is achieved by linear extrapolation of the input images. In this paper, we adapt the unsharp masking technique for 3D shape deblurring purposes. Consider a blurred shape represented by a triangle mesh. Usually such a shape results from a 3D data corrupted by noise and then oversmoothed. First we apply unsharp masking to the mesh normals. To smooth the led of mesh normals we use several local averaging iterations applied to the mesh normals (iterative mean ltering). Then we apply linear extrapolation of the original and smoothed elds of normals. Finally we reconstruct the deblurred mesh by integrating the eld of extrapolated normals. We also give a quantitative evaluation of the proposed unsharp masking technique. To perform the evaluation, we use L2 error metrics on mesh vertices and normals. Experimental results show that the unsharp masking technique is e ective for shape deblurring.
Event-Triggered Finite-Time Sliding Mode Control for Leader-Following Second-Order Nonlinear Multi-Agent Systems

Finite-time leader-following consensus problem of second-order multi-agent system (MAS) with nonlinear dynamics under directed communication topology is investigated in this paper. Based on the event triggered mechanism, a novel finite-time integral sliding mode control strategy is proposed to guarantee that the consensus stability of MAS can be reached within the upper limit of the time, which can be predicted according to the initial state of MAS. The event-triggered condition on the basis of the defined novel measurement error effectively reduces the energy dissipation of the system and the update frequency of the controller, and the deduced lower bound expression of the event-triggered time interval avoids the occurrence of zeno behavior. Numerical simulation results illustrate the effectiveness and feasibility of the proposed algorithm.
‘Sunrouge’, a New Tea Cultivar with High Anthocyanin

Sunrouge’ is an anthocyanin-rich tea cultivar, which was selected from the population derived from the natural crossing of ‘Cha Chuukanbohon Nou 6’ (C. taliensis X C. sinensis). The anthocyanin content of ‘Sunrouge’ exceeded that of ‘Cha Chuukanbohon Nou 6’, which was bred as an anthocyaninrich tea parental line. However the anthocyanin content of ‘Cha Chuukanbohon Nou 6’ depends on the plucking period, growth stage and the part of the new shoot. The emergence of the ‘Sunrouge’ crop is moderately early, as with the Japanese leading cultivar ‘Yabukita’ (C.sinensis var. sinensis). The ‘Sunrouge’ tree is of the medium type and has many branches in comparison to typical cultivars. In terms of resistance, it is slightly resistant to anthracnose (Discula theae-sinensis (I. Miyake) Moriwaki & Toy. Sato comb. nov.), highly resistant to gray blight (Pestalotiopsis longiseta (Spegazzini) Dai & Kobayashi) and has relatively low resistance to brown blight (Glomerella cingulata (Stoneman) Spaulding & Schrenk). The survival rate of ‘Sunrouge’ is lower than ‘Yabukita’ and the other control cultivars in the cutting propagation. We try to propagate using the photoautotrophic culture method and the propagation of ‘Sunrouge’ was incident-free. We anticipate its use as a functional food and the material of the natural pigment.

Mitigation of Acrylamide Content in Biscuits through Combined Physical and Chemical Strategies

Acrylamide in biscuits represents a major concern. This research work was aimed at modifying the current formulation of biscuits to reduce the acrylamide content while maintaining the chemical, physical, and sensory characteristics of the original product. A strategy based on the FoodDrinkEurope Acrylamide Toolbox was adopted. The content of the leavening agent ammonium bicarbonate, the baking temperature program, and the time duration of steam released during the baking process were the three factors evaluated through a factorial design of experiment. The partial replacement of ammonium bicarbonate (from 9.0 g to 1.5 g per 500 g of flour) with sodium bicarbonate (from 4.5 g to 12.48 g), lowering of the temperature in the central phase of the baking process (from 170 °C to 150 °C), and the release of steam for 3 min resulted in an 87.2% reduction in acrylamide concentration compared to biscuits of reference. CIELab color indices and aw were the parameters that showed the most significant correlation with acrylamide concentration in biscuits and could, therefore, become markers to predict the acrylamide content along production lines for an instant evaluation.
Outdoor validation of the 30 minutes intermittent tracking of 100 x CPV

HCPV uses trackers, but their cost and reliability have raised problems. These problems may be solved by substantially increasing acceptance angle and mechanical tolerance. For a demonstration of the possibility of such substantial improvement, a 30 minutes intermittent tracking in high concentration applications was examined. To allow for 30 minutes intermittent tracking, both advanced optics and an advanced tracking control were investigated. For advanced optics, a 100 x refractive and dielectric concentrator was designed. It had about plus or minus 5° of acceptance angle. For advanced tracking control, a feed-forward control with a linear error correction was investigated. With combining both optimizations, it was shown that 30 minutes intermittent tracking was validated in outdoor experiments even for an as high as 100 x concentration.
Prmt7 Downregulation in Mouse Spermatogonia Functions through miR-877-3p/Col6a3

Protein arginine methyltransferases 7 (Prmt7) is expressed in male germ cells, including primordial germ cells, gonocytes, and spermatogonia. Our previous study demonstrated that Prmt7 downregulation reduced the proliferation of GC-1 cells (a cell line of mouse immortalized spermatogonia). However, how Prmt7 regulates spermatogonial proliferation through miRNA and the target gene remains elusive. Here, we experimentally reduced the Prmt7 expression in the GC-1 cells and subjected them to miRNA sequencing to explore the miRNA profile and its Prmt7-responsive members. In total, 48 differentially expressed miRNAs (DEmiRNAs), including 36 upregulated and 12 downregulated miRNAs, were identified. After verifying the validity of sequencing results through qRT-PCR assays in randomly selected DEmiRNAs, we predicted the target genes of these DEmiRNAs. Next, we combined DEmiRNA target genes and previously identified differentially expressed genes between Prmt7 knockdown and control groups of GC-1 cells, which resulted in seven miRNA/target gene pairs. Among these miRNA/target gene pairs, we further detected the expression of Col6a3 (collagen type VI alpha 3) as the target gene of mmu-miR-877-3p. The results suggested that Prmt7 downregulation in mouse spermatogonia might function through miR-877-3p/Col6a3. Overall, these findings provide new insights into the role of Prmt7 in male germ cell development through miRNA and target genes.
IN VITRO ANTIOXYDANT ACTIVITY AND TOTAL PHENOLIC CONTENT OF EXTRACTS FROM THE ENDEMIC ARGANIA SPINOSA (L.) SKEELS FROM ALGERIAN SAHARA

The BuOH fractions prepared from 80% MeOH extract of the leaves from the endemic Saharan tree Argania spinosa (L.) Skeels exhibited the most potent antioxidant capacity ( IC50 = 2.41 ± 0.38 mg/mL for DPPH and 7.95 ± 0.54 mg/mL for superoxide anion radical), compared to the EtOAc and CHCl3 fractions. The results showed that BuOH extract fraction exhibited a strong antioxidant activity and had the most potent scavenging abilities which may be correlated to the presence of Phenolic compounds.
Multiscale deformation measurements using multispectral optical metrology

Remote measurements using images are particularly useful in structural health monitoring cases in which the installation of contact sensors is difficult. Some limitations, though, associated with photogrammetry‐type optical metrology involve the application of speckle patterns, which become even more important with variable working distance or when the required resolution and sensitivity are not a priori known which are both very practical common issues. In this context, multispectral sensing can circumvent some of the challenges of acquiring data at different working distances. The objective of this investigation is therefore to use multispectral imaging combined with the method of digital image correlation to demonstrate an approach for remote sensing related to deformation measurements at the structural level. To demonstrate this novel approach, two speckle patterns were designed for measurements at specified working distances; one was set to work in the visible and the second in the ultraviolet spectrum. The results show that the spectral specific reflectivity of the speckle patterns can be used for spatial overlay without affecting imaging in either spectral range considered, which allows the extraction of multiscale deformation information.
Kinematic Analysis of Tapping Machine and Simulation with Simmechanics

In this study, the design, kinematic analysis and simulation of a 4-degree-of-freedom tapping machine were performed. Solidworks software was used. The design was transferred to the Simmechanics module and transformed into MATLAB blocks. The results of kinematic analysis were introduced to the system with Mfunctions, and the movement of the system was controlled depending on the position input. The tapping machine design is computer controlled and is a suitable solution for tapping on automation supported assembly lines.
Dificuldades, Preocupações e Estresse na Pós-Graduação

Esta pesquisa teve como propósito identificar quais preocupações e dificuldades enfrentadas pelos estudantes na pós-graduação stricto sensu estão relacionadas ao seu nível de estresse, bem como avaliar possíveis correlações entre nível de estresse, desempenho acadêmico percebido e intenção de abando. Para isso, foram investigados 348 estudantes de 53 cursos de mestrado acadêmico e profissional e doutorado acadêmico da Universidade Federal de Uberlândia. Por meio de um estudo quantitativo, com aplicação de testes de regressão linear múltipla e testes de correlação, foram encontrados importantes resultados. Foi identificado que quanto maior o nível de estresse, menor tende a ser o desempenho acadêmico percebido pelos discentes; e quanto maior o nível de estresse dos estudantes, maiores tendem a ser as intenções de abandono do curso. Além disso, as dificuldades e as preocupações que mais fortemente explicam o nível de estresse dos estudantes são: falta de motivação; pressão interna pelo bom desempenho; interferência da demanda dos estudos sobre outros aspectos de sua vida; aspectos financeiros pessoais; dificuldade relativa ao prazo para elaboração da tese ou dissertação; falta de incentivo; e dificuldade de compatibilizar os estudos com a vida pessoal e familiar. Esses achados sugerem que a atenção para o estresse na pós-graduação stricto sensu e a necessidade de um cuidado com os estudantes desse nível de ensino devem compor a formação dos futuros profissionais.
Effectiveness of the Use of Standardized Vocabularies on Epilepsy Patient Cohort Generation

Objectives This study investigated the effectiveness of using standardized vocabularies to generate epilepsy patient cohorts with local medical codes, SNOMED Clinical Terms (SNOMED CT), and International Classification of Diseases tenth revision (ICD-10)/Korean Classification of Diseases-7 (KCD-7). Methods We compared the granularity between SNOMED CT and ICD-10 for epilepsy by counting the number of SNOMED CT concepts mapped to one ICD-10 code. Next, we created epilepsy patient cohorts by selecting all patients who had at least one code included in the concept sets defined using each vocabulary. We set patient cohorts generated by local codes as the reference to evaluate the patient cohorts generated using SNOMED CT and ICD-10/KCD-7. We compared the number of patients, the prevalence of epilepsy, and the age distribution between patient cohorts by year. Results In terms of the cohort size, the match rate with the reference cohort was approximately 99.2% for SNOMED CT and 94.0% for ICD-10/KDC7. From 2010 to 2019, the mean prevalence of epilepsy defined using the local codes, SNOMED CT, and ICD-10/KCD-7 was 0.889%, 0.891% and 0.923%, respectively. The age distribution of epilepsy patients showed no significant difference between the cohorts defined using local codes or SNOMED CT, but the ICD-9/KCD-7-generated cohort showed a substantial gap in the age distribution of patients with epilepsy compared to the cohort generated using the local codes. Conclusions The number and age distribution of patients were substantially different from the reference when we used ICD-10/KCD-7 codes, but not when we used SNOMED CT concepts. Therefore, SNOMED CT is more suitable for representing clinical ideas and conducting clinical studies than ICD-10/KCD-7.
