Sex is no determinant of cardioprotection by ischemic preconditioning in rats, but ischemic/reperfused tissue mass is for remote ischemic preconditioning

We determined the impact of sex on the magnitude of cardioprotection by local and remote ischemic preconditioning (IPC and RIPC) and of ischemic/reperfused peripheral tissue mass on protection by RIPC. Hearts of female and male Lewis rats were excised, perfused with buffer, and underwent either IPC by 3 × 5/5 min global zero‐flow ischemia/reperfusion (GI/R) or time‐matched perfusion (TP) before 30/120 min GI/R. In a second approach, anesthetized female and male Lewis rats underwent RIPC, 3 × 5/5 min ischemia/reperfusion of one or both hindlimbs (1‐RIPC or 2‐RIPC), or placebo. Thirty minutes after the RIPC/placebo protocol, hearts were excised and subjected to GI/R. In female and male hearts, infarct size was less with IPC than with TP before GI/R (IPC+GI/Rfemale: 12 ± 5%; IPC+GI/Rmale: 12 ± 7% vs. TP+GI/Rfemale: 33 ± 5%; TP+GI/Rmale: 37 ± 7%, P < 0.001). With 2‐RIPC, infarct size was less than with 1‐RIPC in female and male rat hearts, respectively (2‐RIPC+GI/Rfemale: 15 ± 5% vs. 1‐RIPC+GI/Rfemale: 22 ± 7%, P = 0.026 and 2‐RIPC+GI/Rmale: 16 ± 5% vs. 1‐RIPC+GI/Rmale: 22 ± 8%, P = 0.016). Infarct size after the placebo protocol and GI/R was not different between female and male hearts (36 ± 8% vs. 34 ± 5%). Sex is no determinant of IPC‐ and RIPC‐induced cardioprotection in isolated Lewis rat hearts. RIPC‐induced cardioprotection is greater with greater mass of ischemic/reperfused peripheral tissue.
Development of a Method for Assessing Design Creativity

Creativity is regarded as a core ingredient of innovation as it enhances the possibility of generating superior products. The core components of creativity are ‘novelty’ and ‘usefulness’ and a direct measure of creativity should be in terms of measuring these components. This paper proposes a method for assessing creativity of technical products. Empirical studies have been conducted to validate this method. First this paper reviews existing methods for measuring ‘novelty’ of technical products, proposes a new method for measuring novelty, and evaluates the proposed method and the existing measures by benchmarking them against the intuitive notion of creativity of experienced designers. Next, it reviews existing literature on ‘usefulness’, proposes a method for assessing usefulness of technical products, and evaluates this by comparing its outcome with the outcome of the existing methods taking the evaluation by experienced designers as reference. Later, ‘creativity’ measures for these products are calculated using the values of the novelty and usefulness of the products and benchmarked against the outcomes of intuitive evaluation of creativity of these products by experienced designers.
The Formation of Protein Structure

Several of the more amazing phenom­ ena in living biological systems concern their ability to form structure. At the macroscopic level it is the ability to form shape the process of morphogenesis. On the cellular scale it is the capacity to selforganize and assemble molecules to form larger aggregated structures. On the molecular scale it is the ability of chain molecules such as DNA and proteins to acquire specific three-dimensional struc­ tures an ability which to our knowledge is only utilized in biological systems so far. Proteins form reproducible structures, i.e., chemically identical proteins acquire identical three-dimensional structures. This may not seem surprising at first. However, it is a unique characteristic as other long polymers do not possess this ability. The process whereby proteins acquire their reproducible structures is called protein folding. Protein folding the formation of structure in proteins is of fundamental importance in biological systems because the ability of a protein to perform a function to act as an enzyme, for instance is fundamentally connected with the structure of the protein.

Mónica Rodrigues Barbosa Evolution of antifungal drug resistance in Candida albicans Evolução de resistência a drogas em Candida albicans

The human pathogen Candida albicans is characterized by the presence of a hybrid tRNA (tRNACAG Ser ) that can be aminoacylated by both LeuRS and SerRS. This tRNA is responsible for the ambiguity of the CUG codon that can be decoded as serine (97%) and Leucine (3%). Previous studies showed that the level of ambiguity is variable depending on the growth condition of the fungus. These studies also revealed that strains mistranslating at a higher level grew better in the presence of azoles, particularly in the presence of fluconazole. To analyse the effect of translation errors on the acquisition of drug resistance, three strains of C. albicans were used (T0, T1 and T2). These strains have increasing levels of Leu misincorporation and were constructed by inserting a copy (T1) or two copies (T2) of a tDNACAG Leu gene. These strains were evolved experimentally in the presence and absence of the antifungal agent according to the approved EUCAST protocol. The level of ambiguity of all strains was measured along the evolution experiment, using a reporter system based on the green fluorescent protein (GFP). Finally, the type of acquired resistance was also evaluated (genetic or phenotypic resistance). Experimental data suggest that the acquisition of resistance is dependent on the drug and the percentage of mistranslation. Strains with increased mistranslation (T2) acquired more resistance (256 μg/ml) and faster than the control T0. Mutations in ERG11 gene might be responsible for this resistance. Also, T2 strain showed a decrease in the mistranslation level during both evolution experiments (with and without drug) as a consequence of the deletion of one of the two copies of the mutant tDNACAG Leu gene. This result further highlights the genetic instability of strain T2.
Partner Selection in Supply Chain of Vietnam’s Textile and Apparel Industry: The Application of a Hybrid DEA and GM (1,1) Approach

Vietnam is currently among the top-five textile and apparel exporters, and the industry is considered quite attractive to foreign investors. Nevertheless, the global textile and garment industry is experiencing important changes. The three main producing regions in the world are China, Southwest Asia (India, Pakistan, Bangladesh, and Turkey), and ASEAN. In order to maintain its positioning and to establish stable and sustainable Vietnam textile and apparel development, there must be radical changes. Due to this necessity, the authors conducted this study by using grey forecasting to predict and reflect the condition of businesses in the period of 2017–2020, together with combining a DEA model to help businesses select the most appropriate strategic partner in the supply chain in order to achieve economic goals and promote the strength of the businesses partaking in the association. Besides, this helps businesses exploit market opportunities and take advantage of the capabilities of the textile and apparel industry.
Frontal Lobe Theta Activity in Socially Ostracized Individuals: Understanding Social Ostracism through EEG

The present study used a chat room paradigm to examine the effects of social ostracism on theta EEG activity in the frontal lobe. Participants were placed in an online chat room with two other individuals whose chat room profiles indicated they were both the opposite gender of the participant and attending other universities in central Illinois. Unknown to participants, these individuals were actually confederates in the study, and the pictures used on these profiles had previously been rated as either attractive or unattractive by college students. This experiment consisted of three primary phases. In the first phase, confederates actively included the participant in the chat room conversation. In the second phase, the participant was completely ignored (social ostracism manipulation). Confederates re-included the participant in the last phase of the chat room conversation. The purpose of the present study was to investigate variables that may influence the experience of social ostracism, such as gender and attractiveness of the ostracizing students. Results indicated that the ostracism manipulation was successful, with participants reporting significantly lowered enjoyment, interest, participation, and overall engagement during exclusion, while EEG data showed a non-significant trend for lowered theta power during exclusion that did not reach significance. Attractiveness of ostracizing peers played a role in the chat room experience, with participants reporting greater engagement with unattractive peers and male participants showing a larger difference in engagement between attractiveness conditions. In addition, there was a significant interaction between phase and attractiveness condition in theta EEG activity. No gender main effects were documented in self­ report or EEG data. Future research is needed to continue to examine the roles that gender and attractiveness play in social ostracism.
Geographic parthenogenesis in the Australian arid zone: I. A climatic analysis of the Heteronotia binoei complex (Gekkonidae)

Patterns of geographic parthenogenesis can provide insight into the ecological implications of the transition from sexual to parthenogenetic reproduction. We analysed quantitatively the environmental niches occupied by sexual and parthenogenetic geckos of the Heteronotia binoei complex in the Australian arid zone. This complex consists of two independently derived maternal lineages of hybrid parthenogens, which, in turn, include two different triploid races that resulted from reciprocal backcrossing with the parental sexual taxa. The sexual progenitors are still extant and occupy very distinct environmental niches. The triploid parthenogenetic races are biased in their environmental niche towards those of the sexual races for which their genomes are biased and this dosage effect is apparent in both maternal lineages. Thus triploidy may have benefited the parthenogens through partial recovery of the parental niches. Although the parthenogens have a broader geographic distribution than their sexual progenitors, their environmental niche is narrower and biased towards one of the sexual races. In keeping with general patterns of geographic parthenogenesis, parthenogenetic H. binoei occupy a harsher environment than the sexual forms, occurring in regions of persistently low rainfall. Bioclimatic modelling suggests patterns of rainfall are important in limiting the distribution of sexual and parthenogenetic taxa, and extrapolation from the current bioclimatic profiles indicates potential for further eastward range expansion by the parthenogens.
Comparison between PI and PR Current Controllers of a Grid-Connected Photovoltaic System Supplying Nonlineare Load

This paper presents a three-phase grid-connected PV system supplying nonlinear load, which controls active power and harmonic compensation. A Proportional-Resonant (PR) controller is used for replacing the conventional Proportional-Integral (PI) controller in this system. By comparison with the conventional PI control method, the PR control can introduce an infinite gain at the fundamental frequency and hence can achieve zero steady-state error and the grid current can be noticeable sinusoidal and current harmonics generated by the nonlinear load will be compensated. In order to examine the effectiveness of the suggested control, a simulation using the Matlab/Simulink software has been done. The simulation results confirm the validation of the presented control and shows the efficiency of the PR controller especially with respect to the harmonics created by the nonlinear load, which proves that the use of this type of controller ensure a better energy transport to grid with fewer harmonics.
Learning innovation and proximity. An empirical exploration of patterns of learning: a case study

A growing body of theoretical research is addressing the importance of learning in the organisational and technological renewal of firms, and therefore in their efforts to improve competitiveness (Daft & Huber, 1987; Levitt & March, 1988; Huber, 1991; Dodgson, 1993; Blackler, 1995; Dodgson, 1996). In these discussions, regions are thought to have important features for facilitating innovation too (Florida, 1995, Cooke, Gomez Uranga, Etxebarria, 1997; Morgan, 1997). This paper reviews literature on organisational learning and networks, learning regions as systems of innovation, and the role of proximity in the transfer of information and knowledge. Literature on organisational learning and regional systems of innovation takes the embeddedness or relational perspective on innovation as a point of departure. Moreover, in studies on proximity the existence of embeddedness is often taken for granted. But, is embeddedness always as important for innovation as assumed? And is proximity really of importance in systems of innovations? In this paper, these questions are explored empiricaIly. After a brief discussion of theoretical literature on organisational learning, economic networks, and spatial proximity, the paper focuses on the empirical exploration of patterns of learning in a specific Dutch region. Learning organisations are depicted as problem-solving actors. In coping with innovation problems, actors participate in different kinds of networks. Finally, the spatial dimension of these networks is investigated.

A Radio-Frequency-over-Fiber link for large-array radio astronomy applications

A prototype 425-850 MHz Radio-Frequency-over-Fiber (RFoF) link for the Canadian Hydrogen Intensity Mapping Experiment (CHIME) is presented. The design is based on a directly modulated Fabry-Perot (FP) laser, operating at ambient temperature, and a single-mode fiber. The dynamic performance, gain stability, and phase stability of the RFoF link are characterized. Tests on a two-element interferometer built at the Dominion Radio Astrophysical Observatory for CHIME prototyping demonstrate that RFoF can be successfully used as a cost-effective solution for analog signal transport on the CHIME telescope and other large-array radio astronomy applications.
Fusion network performance experiment

Hybrid optical packet/circuit switched networking architectures are increasingly becoming an interesting research field. They integrate multiple switching techniques to achieve better quality of service and to improve resource utilization. The aim of this study was to investigate the performance of TransPacket FUSION Ethernet H1 node, which is being developed based on the original idea of OpMiGua hybrid optical network. The work was focused on several key performance elements: packet delay, packet loss rate and packet delay variation of the hybrid network. The research background and the quality of service methods utilized in hybrid network and OpMiGua were studied in this project. The performance of H1 node was tested based on one applicable scenario. We investigated and analyzed the results obtained from the Spirent test center, and derived a mathematical model of H1 node performance respect to each aspect. Furthermore, the experiment results were verified with usability of H1 node in comparison with the ITU recommendations. The results in our experiment scenario showed that H1 node provides a high quality of service.
k-Nearest Neighbors Algorithm in Profiling Power Analysis Attacks

Power analysis presents the typical example of successful attacks against trusted cryptographic devices such as RFID (Radio-Frequency IDentiﬁcations) and contact smart cards. In recent years, the cryptographic community has explored new approaches in power analysis based on machine learning models such as Support Vector Machine (SVM), RF (Random Forest) and Multi-Layer Perceptron (MLP). In this paper, we made an extensive comparison of machine learning algorithms in the power analysis. For this purpose, we implemented a veriﬁcation program that always chooses the optimal settings of individual machine learning models in order to obtain the best classiﬁcation accuracy. In our research, we used three datasets, the ﬁrst contains the power traces of an unprotected AES (Advanced Encryption Standard) implementation. The second and third datasets are created independently from public available power traces corresponding to a masked AES implementation (DPA Con-test v4). The obtained results revealed some interesting facts, namely, an elementary k-NN (k-Nearest Neighbors) algo-rithm, which has not been commonly used in power analysis yet, shows great application potential in practice.
SpinachBase: a central portal for spinach genomics

Abstract Spinach (Spinacia oleracea L.) is a nutritious vegetable enriched with many essential minerals and vitamins. A reference spinach genome has been recently released, and additional spinach genomic resources are being rapidly developed. Therefore, there is an urgent need of a central database to store, query, analyze and integrate various resources of spinach genomic data. To this end, we developed SpinachBase (http://spinachbase.org), which provides centralized public accesses to genomic data as well as analytical tools to assist research and breeding in spinach. The database currently stores the spinach reference genome sequence, and sequences and comprehensive functional annotations of protein-coding genes predicted from the genome. The database also contains gene expression profiles derived from RNA-Seq experiments as well as highly co-expressed genes and genetic variants called from transcriptome sequences of 120 cultivated and wild Spinacia accessions. Biochemical pathways have been predicted from spinach protein-coding genes and are available through a pathway database (SpinachCyc) within SpinachBase. SpinachBase provides a suite of analysis and visualization tools including a genome browser, sequence similarity searches with BLAST, functional enrichment and functional classification analyses and functions to query and retrieve gene sequences and annotations.
CFD and experimental investigation into a non‐intrusive method for measuring cooling air mass flow rate through a synchronous generator

This study presents a detailed methodology for non-intrusive measurement of cooling air mass flow rate that enables an overall machine evaluation. This approach enables the simultaneous measurement of air mass flow with shaft torque at differing operating points while minimising the change in air flow introduced by the measurement system. The impact of geometric parameters in the designed system is investigated using a detailed 180° computational fluid dynamics (CFD) model. Special attention was paid to minimising their influence on pressure drop, the mass flow rate through the machine, and measurement uncertainty. Based on the results of this investigation, the system was designed and manufactured, and the experimentally measured data was used to validate the CFD predictions. For the as optimal identified configuration, the flow rate is predicted to decrease by 2.2% relative to unrestricted operation. The achieved measurement uncertainty is ± 2.6% at synchronous speed.
