Curiosity Killed the Cat but Not Memory: Enhanced Performance in High-Curiosity States

Curiosity benefits memory for target information and may also benefit memory for incidental information presented during curiosity states. However, it is not known whether incidental curiosity-enhanced memory depends on or is affected by the valence of the incidental information during curiosity states. Here, older and younger participants incidentally encoded unrelated face images (positive, negative, and neutral) while they anticipated answers to trivia questions. We found memory enhancements for answers to trivia questions and unrelated faces presented during high-curiosity compared with low-curiosity states in both younger and older adults. Interestingly, face valence did not modify memory for unrelated faces. This suggests processes associated with the elicitation of curiosity enhance memory for incidental information instead of valence.
Broadbanding and multi-frequency in dielectric resonator antennas: a comprehensive review

Abstract Dielectric resonator antennas (DRAs) are developed antennas that are lightweight, wideband, small-sized and have high radiation efficiency. A DRA is an appropriate candidate for any radio communication including radar applications mainly because of its high efficiency and wideband performance. As the development of DRAs has been a continuous process for more than five decades the plethora of the same has become magnificent in all possible ways. Scientists have walked the technical path for more than centuries and tried to meet the various challenges in the most graceful ways. Reduction of loss, lightweight, and desired radiation patterns are some of the issues which are effectively met by DRAs. This paper presents a brief comprehensive review of the state of art techniques, giving an exhaustive idea of achieving broadband and multi-frequency operations in the areas of DRAs. The paper associates the references of the past and correlates with the current and future trends of research in DRAs that could be of immense help to the young upcoming researchers interested in this field.

The effectively optical emission modulation in perovskite MAPbBr3 crystal by hot-electron transfer from metals

Optical emission modulation is an effective way to improve material properties and to enlarge their applications. However, a significant problem still facing challenge is low efficiency in optical emission enhancement. To contribute this, this work aims to achieve efficient hot electron transfer resulting emission enhancement used the help of plasmon resonance near-field enhancement and combined with excitation energy. Thus, a simply method of metal-perovskite heterojunctions preparation was conducted. The optical crystal of Au nanoparticles/nanocages attached on perovskite MAPbBr3 (NP-C) is presented. The hot electron transfer signal in ion’s vibration is characterized by XRD and Raman spectrum firstly. The cube shape and size distribution mostly in 550–850 nm morphology is revealed by SEM. The carrier concentration is improved about 37.5%, the mobility and resistivity are lowered around 53.2% and 26.7% after soaking in solution, respectively. What’s importantly, the effective modulation of intensity and peak position are achieved at room temperature, which is caused by the behavior of hot-electrons transfer suggested by FDTD simulation. The evidence for hot-electron transfer at the interface in Au–MAPbBr3 in 150 fs are proved by transient absorption spectrum. Finally, the mechanism of optical modulation, band gap structure and hot electrons transfer are depicted. This paper can provide experimental reference for emission enhancement and the development of devices based on hot electrons transfer.
Hip Abductor Muscle Fatigue Induces Different Strategies During Disrupted Postural Control

Background Ankle sprain is one of the most common injuries in sport, and hip abductor muscle weakness has recently been reported as a predisposing factor. Currently, the influence of hip abductor muscle fatigue on ankle joint control has not been elucidated during an ankle disturbed balance exercise. This study aimed to determine the influence of hip abductor muscle fatigue on ankle joint control during a disturbed balance task, and to consider inter-individual variability in the kinematic and neuromuscular reorganizations implemented. Methods Twenty-six healthy subjects (13 males; 13 females) performed a unipedal postural balance task with eyes closed before and after a fatiguing exercise (up to a 50% decrease in strength) of the hip abductor muscles. Subjects completed balance task while equipped with an ankle destabilization device that allows inversion/eversion movements. Electromyographic (EMG) activity of the gastrocnemius lateralis (GastL), peroneus longus (PL) and brevis, tibialis anterior, and gluteus medius were recorded during task. Kinematics (e.g., frontal foot angulation) of the ankle complex were determined using inertial measurement units. Results In the overall group, no significant time, sex or interaction effect was observed for kinematic and EMG variables. However, when considering individual responses to hip fatigue, 14 subjects decreased the standard deviation of frontal angulation (−30%) suggesting enhancement of ankle joint control, while 12 subjects increased it (+46%). Normalized EMG for PL and GastL muscles changed with fatigue for both these groups. However, variations were significantly different between groups (p = 0.027 for PL and p = 0.006 for GastL). Indeed, the contribution of ankle muscles increased for the enhanced-stability group while no change for the impaired-stability group. Conclusion These results highlight that subject adopt different neuromuscular and kinematic ankle strategies to control ankle destabilization in response to hip abductor muscle fatigue. Frontal foot angulation variability seemed to be a valuable marker to detect the type of strategy employed. The strategy adopted by the impaired-stability group might have important implications when analyzing risk factors for ankle sprains. Further studies should consider individual responses to fatigue, to understand which factor could predispose athletes to use of one or other strategy.
Evaluating the Antagonistic Potential of Actinomycete Strains Isolated From Sudan’s Soils Against Phytophthora infestans

Soil microorganisms play crucial roles in soil fertility, e.g., through decomposing organic matter, cycling nutrients or through beneficial interactions with plants. Actinomycetes are a major component of soil inhabitants; they are prolific producers of specialized metabolites, among which many antibiotics. Here we report the isolation and characterization of 175 Actinomycetes from rhizosphere and bulk soil samples collected in 18 locations in Sudan. We evaluated the strains’ metabolic potential for plant protection by testing their ability to inhibit the mycelial growth of the oomycete Phytophthora infestans, which is one of the most devastating plant pathogens worldwide. Most strains significantly reduced the oomycete’s growth in direct confrontational in vitro assays. A significant proportion of the tested strains (15%) were able to inhibit P. infestans to more than 80%, 23% to 50%–80%, while the remaining 62% had inhibition percentages lesser than 50%. Different morphologies of P. infestans mycelial growth and sporangia formation were observed upon co-inoculation with some of the Actinomycetes isolates, such as the production of fewer, thinner hyphae without sporangia leading to a faint growth morphology, or on the contrary, of clusters of thick-walled hyphae leading to a bushy, or “frozen” morphology. These morphologies were caused by strains differing in activity levels but phylogenetically closely related with each other. To evaluate whether the isolated Actinomycetes could also inhibit the pathogen’s growth in planta, the most active strains were tested for their ability to restrict disease progress in leaf disc and full plant assays. Five of the active strains showed highly significant protection of potato leaves against the pathogen in leaf disc assays, as well as substantial reduction of disease progress in full plants assays. Using cell-free filtrates instead of the bacterial spores also led to full protection against disease on leaf discs, which highlights the strong crop protective potential of the secreted metabolites that could be applied as leaf spray. This study demonstrates the strong anti-oomycete activity of soil- and rhizosphere-borne Actinomycetes and highlights their significant potential for the development of sustainable solutions based on either cell suspensions or cell-free filtrates to safeguard potatoes from their most damaging pathogen.
Cancer Stem Cell-Associated Immune Microenvironment in Recurrent Glioblastomas

Glioblastoma multiforme (GBM) is the most incurable tumor (due to the difficulty in complete surgical resection and the resistance to conventional chemo/radiotherapies) that displays a high relapse frequency. Cancer stem cells (CSCs) have been considered as a promising target responsible for therapy resistance and cancer recurrence. CSCs are known to organize a self-advantageous microenvironment (niche) for their maintenance and expansion. Therefore, understanding how the microenvironment is reconstructed by the remaining CSCs after conventional treatments and how it eventually causes recurrence should be essential to inhibit cancer recurrence. However, the number of studies focusing on recurrence is limited, particularly those related to tumor immune microenvironment, while numerous data have been obtained from primary resected samples. Here, we summarize recent investigations on the immune microenvironment from the viewpoint of recurrent GBM (rGBM). Based on the recurrence-associated immune cell composition reported so far, we will discuss how CSCs manipulate host immunity and create the special microenvironment for themselves to regrow. An integrated understanding of the interactions between CSCs and host immune cells at the recurrent phase will lead us to develop innovative therapies and diagnoses to achieve GBM eradication.
Hybrid Contract in Islamic Financial Services

The hybrid contract is needed to accommodate modern transactions unavailable in the classical Islamic period. The current financial service products use hybrid contracts, such as in debt transfer, import and export letters of credit, and credit cards. The evaluation of the use of contracts in these products reveals the use of multiple alternative contracts in debt transfer and Letters of Credit; and single contract alternative for credit card services. This study shows the complexity of contracts in modern financial products, requiring more complex documentation. The merger of several contracts in one transaction is based on the argument that there is no prohibition on using multiple contracts in one transaction, as long as it avoids usury (ribā). AbstrakPenggabungan akad merupakan kebutuhan untuk mewadahi transaksi modern yang tidak ditemukan di masa Islam klasik. Bentuk penggabungan akad tersebut terjadi di antaranya pada produk jasa keuangan modern seperti pengalihan utang, Letter of Credit impor dan ekspor, dan kartu kredit. Dengan mengevaluasi penggunaan akad-akad dalam produk tersebut ditemukan beberapa alternatif penggabungan akad pada produk pengalihan hutang dan Letter of Credit, serta satu alternatif penggabungan akad untuk produk kartu kredit. Penggabungan akad tersebut didasarkan atas argumen tidak ada larangan penggabungan akad selama tidak menimbulkan ribā. Hasil penelitian ini menunjukkan kompleksitas akad pada produk keuangan modern yang pada praktiknya membutuhkan dokumentasi yang lebih kompleks.
Effects of Immunoglobulins G From Systemic Sclerosis Patients in Normal Dermal Fibroblasts: A Multi-Omics Study

Autoantibodies (Aabs) are frequent in systemic sclerosis (SSc). Although recognized as potent biomarkers, their pathogenic role is debated. This study explored the effect of purified immunoglobulin G (IgG) from SSc patients on protein and mRNA expression of dermal fibroblasts (FBs) using an innovative multi-omics approach. Dermal FBs were cultured in the presence of sera or purified IgG from patients with diffuse cutaneous SSc (dcSSc), limited cutaneous SSc or healthy controls (HCs). The FB proteome and transcriptome were explored using liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) and microarray assays, respectively. Proteomic analysis identified 3,310 proteins. SSc sera and purified IgG induced singular protein profile patterns. These FB proteome changes depended on the Aab serotype, with a singular effect observed with purified IgG from anti-topoisomerase-I autoantibody (ATA) positive patients compared to HC or other SSc serotypes. IgG from ATA positive SSc patients induced enrichment in proteins involved in focal adhesion, cadherin binding, cytosolic part, or lytic vacuole. Multi-omics analysis was performed in two ways: first by restricting the analysis of the transcriptomic data to differentially expressed proteins; and secondly, by performing a global statistical analysis integrating proteomics and transcriptomics. Transcriptomic analysis distinguished 764 differentially expressed genes and revealed that IgG from dcSSc can induce extracellular matrix (ECM) remodeling changes in gene expression profiles in FB. Global statistical analysis integrating proteomics and transcriptomics confirmed that IgG from SSc can induce ECM remodeling and activate FB profiles. This effect depended on the serotype of the patient, suggesting that SSc Aab might play a pathogenic role in some SSc subsets.
A Snapshot of Microbial Succession and Volatile Compound Dynamics in Flat Peach Wine During Spontaneous Fermentation

Flat peaches possess characteristic flavors and are rich in nutrients. The fermentation of flat peaches to produce wine through complex biochemical reactions is an effective method to overcome their seasonal defects. Spontaneously fermented flat peach wine has plentiful and strong flavors, but the microbiota of fermentation are still unknown. In this study, the microbial succession and volatile compound dynamics of spontaneous fermentation in Xinjiang flat peach wine were investigated using high-throughput sequencing (HTS) and headspace solid phase microextraction (HS-SPME) coupled with gas chromatography-mass spectrometry (GC-MS) technology, respectively, to better understand the microbiota involved. Multivariate data analysis was used to predict the relationship between microorganisms and volatile chemicals. The results showed that Kazachstania, Pichia, Aspergillus, Fructobacillus, Leuconostoc, and Lactobacillus were the dominant genera during the spontaneous fermentation of flat peach wine. Furthermore, ethyl hexanoate, 3-hexen-1-yl acetate, ethyl caprate, ethyl caprylate, phenethyl acetate, ethanol, γ-decalactone, decanal, 1-hexanoic acid, and octanoic acid endued flat peach wine with a strong fruity and fatty aroma. The core functional microbiota (primarily consisting of 11 bacterial and 14 fungal taxa) was strongly associated with the production of 27 volatile compounds in the spontaneously fermented flat peach wine, according to multivariate data analysis. Some alcohols and esters were positively linked with the presence of Kazachstania and Pichia. Meanwhile, the presence of Fructobacillus, Leuconostoc, Lactobacillus, and Weissella was significantly correlated with 2-non-anol, ethanol, 3-methyl-1-butanol, octyl formate, isoamyl lactate, and ethyl lactate. This snapshot of microbial succession and volatile compound dynamics provides insights into the microorganisms involved in flat peach wine fermentation and could guide the production of flat peach wine with desirable characteristics.
Design and Implementation of an IoT System for Smart Energy Consumption and Smart Irrigation in Tunnel Farming

Efficient and cost effective ways of irrigation have emerged as the need of the hour due to limited sweet water resources, especially the countries that are seriously hit by a lack of sweet water reservoirs. The majority of the water is wasted due to inefficient ways of watering plants. In this paper, we propose an intelligent approach for efficient plant irrigation that has a database of daily water needs of a type of plant and decides the amount of water for a plant type on the basis of the current moisture in soil, humidity, and time of the day. This approach not only saves sweet water by efficient utilization, but also supports smart consumption of energy. Our approach employs IoT and a set of sensors to efficiently record plant data and their watering needs and the approach is implemented with a mobile phone application interface that is used to continuously monitor and control the efficient watering system. The results of this study are easy to reproduce as the sensors used are cheap and easy to access. The study discusses in this paper is experimented on small area (such as tunnel farm) but the results of the experiments show that the used approach can be generalized and can be used for large size fields for efficient irrigation. The results of the experiments also outperform the manual approach and the similar approaches for sensor based irrigation systems.
Turbo-estimation de canal pour les systèmes OFDM utilisant des préambules

In this article, we present an iterative semi-blind channel estimation algorithm, for OFDM systems relying on preamble. Compared to simple estimation, based on preamble averaging, gains are 1,5dB or better. When Doppler is high, the proposed algorithm still keeps system working whereas simple estimation algorithm does not. This work is based on an optimal iterative algorithm [1][2][3], relying on the Maximum A Posteriori criterion (MAP), and uses the Expectation-Maximization algorithm (EM) [4][5] The algorithm uses a particular representation of the OFDM channel, using Karhunen-Loeve decomposition theorem [6]. Channel estimates are projected on a sub-space obtained with this representation. From this algorithm we developed six modifications. First a channel tracking algorithm was set up to cope with Doppler variations, without the help of pilots. Another modification is proposed to adapt to 16QAM case. More, receiver complexity has been reduced thanks to 2x1D projection, update formula modification, and the use of a hard output decoder. Last, we study algorithm performances under bad knowledge of channel statistics. 1.

Mindfulness Meditation as Psychosocial Support in the Breast Cancer Experience: A Case Report

In the last decade, Mindfulness-based interventions have been increasingly used in health care settings, particularly in the context of cancer. Research documents the efficacy of these interventions for decreasing the burdens of stress, anxiety, depression, fatigue, sleep disorders, and other symptoms. This article describes the case report of a patient with breast cancer, highlighting her personality, defense mechanisms, and traumatization connected with the disease. General information about the patient’s personal and medical history is presented in addition to the trajectory of psychoncological support, focusing on objectives, intervention strategies based on Mindfulness, and outcomes. The intervention is a combination of individual and group therapies, with particular reference to the use of Mindfulness in a group setting. The goal is to provide the patient with both a peer sharing experience as well as the tools to manage psychoemotional reactions through the development of awareness and a better relationship with herself. The main hypothesized consequences are an increase in self-esteem and coping strategies, which are necessary for a successful adaptation to cancer. The objective of the Mindfulness intervention is to promote the maintenance of an adequate Quality of Life (QoL) and psychological well-being, during and after treatment, transferring these skills into daily life.
Principled practice for drama and theater arts with multilingual learners

ABSTRACT All disciplines have particular ways of knowing, common practices, and means of using language that mediate and potentially support engagement with the discipline. For multilingual learners, language demands of a discipline can be a closed door or a facilitated entryway. Drama and theater arts, the focus of our article, are often marginalized in curricula across the grades and therefore receive less attention to relevant disciplinary activities and language demands. In response to this pattern, our paper has several aims. We highlight ways language demands are embedded in drama and theater arts curricula and activities. Second, we describe and analyze ways instruction can attend to these demands and support multilingual learners’ engagements with them. Third, we distill a set of principles that can guide teachers, guest artists, and teacher educators in their work on drama and theater arts with multilingual student populations. To accomplish these aims, we draw upon our own and others’ teaching and research to frame instructional practices that support multilingual students’ engagements with drama and theater activities. Engagements we describe span early childhood through high school years. Tapping our own work in several US states (Illinois, North Carolina, California), as well as in Argentina and the UK, we present data and themes from a high school study featuring drama and theater arts practices used with multilingual learners. We examine how principles from our framework are illustrated in data of the study. We also identify challenges and critical adaptations that may be needed to realize the potential of drama in work with multilingual students. Principles we identify may aid teachers, guest artists, and teacher educators in shaping drama and theater arts activities that spotlight language demands of the discipline(s) of drama and theater and provide supportive and meaningful instruction.
