Roll of Thunder, Hear My Cry

Since the conception of education in the United States, schools have been the battlegrounds for equal opportunities among African American students. In an effort to improve educational options and achievement for such students, charter schools have emerged as a popular solution for failing schools. The literature and case study in this chapter provides a sociohistorical look at the education of African Americans and African American parents' perceptions of charter schools and their expectations that they hold for educational institutions. The level of hope that was evident from the parent narratives centered on non-academic measures such as cultural pride and caring environments and mirrored that of pre-Brown schools that served African American students. The case study does not suggest that charters are the solution to educational inequity but may serve as one promising avenue for educational reform that should be informed by culturally responsive practices that encourage collaboration between schools and African American families.
Companion diagnostic for the chloroquine use in the treatment of COVID-19: systems biology report of candidate markers.

BACKGROUND Chloroquine is used for the treatment of COVID-19 patients. However, efficacy of the chloroquine has been under discussion. Variability of clinical outputs of the drug application requires implementation of a companion diagnostic that would allow monitoring responsiveness to chloroquine. The first line of such markers would be markers already used in clinics. Analysis of reported mechanisms of COVID-19 and chloroquine may lead to such markers. METHODS Systemic analysis of molecular mechanisms and markers engaged by chloroquine and COVID-19 virus was performed. The networks of regulatory mechanisms were explored for an intersection and relevance to clinical markers. RESULTS Reported here systemic analysis describes the intersection of molecular mechanisms of chloroquine and processes engaged by COVID-19. 266 nodes provide insight into the mechanisms of chloroquine impact on the infection and represent a pool of companion diagnostic markers. As an example, an intersection with the markers of heart arrhythmia retrieved 19 nodes. Thirteen of them were reported in human plasma: levels of albumin, amyloid precursor protein, and endoglin correlate with adverse cardiac effects. CONCLUSIONS Reported nodes are the candidate markers for companion diagnostic of the chloroquine application to COVID-19 patients. Some of these markers are already used in the clinic and their interpretation may contribute to monitoring for adverse effects of chloroquine.
Men Show Higher Neural Sensitivity to Wins – Large or Small – than Women in the Monetary Incentive Delay Task

Background Men and women show differences in sensitivity to reward and punishment, which may impact behavior in health and disease. However, the neural bases of these sex differences remain under-investigated. Here, by combining functional magnetic resonance imaging (fMRI) and a Monetary Incentive Delay Task (MIDT), we examined sex differences in the neural responses to monetary wins and losses and how these regional activities vary with individual reward and punishment sensitivity. Methods Sixty-three healthy adults (27 women) participated in the fMRI study with a 3-Tesla scanner. Sensitivity to punishment (SP) and sensitivity to reward (SR) were assessed with the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ). In the MIDT, participants pressed a button to collect either $1, 1¢, or nil, with the reaction time window titrated across trials to achieve ~67% success. Imaging data were processed with published routines and evaluated with a corrected threshold. Results The results showed higher SP score in women vs. men and higher SR score in men vs. women. Compared to women, men also showed higher response to the receipt of dollar or cent reward in the medial prefrontal cortex, in the area of the supplementary motor cortex. Regional responses to loss did not show sex differences. Further, in a whole-brain regression, activation of the caudate head during 1¢ loss was correlated positively with SR score in men but not in women, and the sex difference was confirmed by a slope test. Conclusions Together, men showed higher SR and neural sensitivity to the receipt of reward, big or small, than women. Individual differences in SR could be reflected by caudate response to a small loss in men. These findings highlight how men and women may differ in reward-related brain activations in the MIDT and add to the imaging literature of sex differences in cognitive and affective functions.
Temperature Dependence of Self-Diffusion Coefficients of Ions and Solvents in Ethylene Carbonate, Propylene Carbonate, and Diethyl Carbonate Single Solutions and Ethylene Carbonate + Diethyl Carbonate Binary Solutions of LiPF6 Studied by NMR

The self-diffusion coefficients, D, of lithium, anions, and solvents in four binary-solution electrolytes of ethylene carbonate (EC)–diethyl carbonate (DEC) and three single-solution electrolytes of EC, DEC, and propylene carbonate (PC) including 1 M LiPF6 were measured by 1H, 7Li, and 19F NMR spectroscopy from (353 to 243) K or above freezing for seven solution electrolytes. In the single DEC electrolyte, DLi and DPF6 had almost the same values at every temperature, whereas DLi was smaller than DPF6 in the EC and PC solutions. In the binary EC–DEC electrolytes, as the ratio of EC increased, DLi gradually became smaller, while DPF6 remained almost unchanged in the temperature range studied. At 303 K, the degree of ion dissociation α was evaluated from the ionic conductivity, DLi and DPF6. The α value increased from 0.17 to 0.71 as the EC ratio increased from (0 to 100) %.

Porin protein could be a vaccine candidate against Riemerella anatipestifer for ducks

such as domestic ducks and geese. Young birds have a high mortality rate after infection. The resistance caused by the abuse of antibiotics is also getting worse. Since there are 25 serotypes of RA, and the cross-immunization between serotypes is weak, it is necessary to find a vaccine that has cross-immunization against multiple serotypes of RA. In this article, the bioinformatics analysis of RA Proin protein was conducted, and it was speculated that it has the potential of a subunit vaccine. The protein was recombinantly expressed and purified, and immunized with Cherry Valley Duck. The results show that the serum antibodies of the Porin protein immunized group were positive at 1:24300 for the porin protein and RA strains CH1. The serum could improve the killing effect of complement and phagocytic cells on RA. After the challenge, the survival rate of Cherry Valley Duck can be increased by 80%.
Aid for Trade, Export Product Diversification and Foreign Direct Investment

The few existing studies on the relationship between Aid for Trade (AfT) flows and Foreign Direct Investment (FDI) inflows tend to report a positive effect of total AfT flows, in particular of Aid flows for building economic infrastructure, on FDI inflows. The present article aims to complement these works by investigating whether the effect of AfT flows on inward FDI stock depends on recipient-countries' level of export product concentration. The empirical analysis has shown that AfT flows exert a strong positive effect on inward FDI stock in countries that experience a high level of export product concentration. These findings are relevant for developing countries in light of the concentration of their export products on primary commodities, and given the strong role of FDI flows for employment generation, economic growth and development in these countries.
miRNA Identification from Jatropha curcas L. whole genome shotgun assembly sequences

miRNAs are 20-25 nucleotide in length, endogenous in origin, and noncoding RNA molecules found in all the eukaryotic organism and takes part in the regulation of gene expression. Jatropha curcas L. oil has drawn attention as one of the most potential biofuels that can be a substitute of never-ending fuel crisis. Six miRNA candidates, each belonging to different miRNA families were predicted after screening of 41,790 whole genome shotgun assembly sequences by using the comparative genomics approach. The targets of identified miRNA were also predicted, the predicted target genes are belonging to diverse functions like in metabolism, transport, and genes involved in fatty acid metabolism. The predicted miRNAs show their targets which involve in the fatty acid metabolism, like miR414 targets the gene of acetyl-CoA carboxylase and O-acyltransferase WSD1, miR846 targets gene of FAD omega-3 fatty acid, FAD plastid fatty acid desaturase, miR5658 have the target gene long chain acyl-CoA synthetase 1, and miR407 have the target gene Trigalactosyldiacylglycerol 2, miR2938 GDSL esterase/lipase, glycolipid transfer protein 1.
Coherent Expanded-Aerogels

Abstract There are few topics in colloid chemistry that have experienced such extensive investigation as that of the structure of gels. Numerous hypotheses have been presented and supported by experimental data of one character or another. Certain aspects of gels have seemed to classify them as solid solutions, others as emulsions, while yet others give strong support to a two-phase, solid-liquid structure. Although the latter theory in similar form to that postulated by Nageli in 1858 has been accepted by most of the foremost colloid chemists, the evidence has not been sufficiently unequivocal to convince all. The evidence presented in the results of diffusion experiments through gels, the fact that the electrical conductivity, refractive index, and vapor pressure before and after setting are identical, at least in certain cases, and the known facts of syneresis would seem to leave little room for doubt of the two-phase nature of gels in general. A theory in order to be perfectly acceptable must, however.
Optimizing Open Data to Support One Health: Best Practices to Ensure Interoperability of Genomic Data from Microbial Pathogens

The holistic approach of One Health, which sees human, animal, plant, and environmental health as a unit, rather than discrete parts, requires not only interdisciplinary cooperation, but standardized methods for communicating and archiving data, enabling participants to easily share what they have learned and allow others to build upon their findings.Ongoing work by NCBI and the GenomeTrakr project illustrates how open data platforms can help meet the needs of federal and state regulators, public health laboratories, departments of agriculture, and universities. Here we describe how microbial pathogen surveillance can be transformed by having an open access database along with Best Practices for contributors to follow. First, we describe the open pathogen surveillance framework, hosted on the NCBI platform. We cover the current community standards for WGS quality, provide an SOP for assessing your own sequence quality and recommend QC thresholds for all submitters to follow. We then provide an overview of NCBI data submission along with step by step details. And finally, we provide curation guidance and an SOP for keeping your public data current within the database. These Best Practices can be models for other open data projects, thereby advancing the One Health goals of Findable, Accessible, Interoperable and Re-usable (FAIR) data.
Conjugation of Gold Nanorods with Bovine Serum Albumin Protein

We used polarized fluctuation correlation spectroscopy (p-FCS) to study the interaction of bovine serum albumin (BSA) with cetyltrimethylammonium bromide (CTAB) stabilized gold nanorods (AuNRs). The translational (DT) and rotational diffusion (DR) of the BSA-NR conjugate were determined in varying concentrations of BSA. The measured diffusion coefficients were analyzed to determine the change of the hydrodynamic size of the particle due to protein adsorption. We found that the saturation coverage is less than one monolayer of protein at a BSA concentration of ≈1 mM. The adsorption isotherm was compared with the Langmuir and anticooperative binding models to quantify BSA-NR association. Our data can be interpreted in terms of hydrophobic interaction between the imperfect CTAB coating and the buried hydrophobic residues of the protein, which results in the loss of protein native conformation. We compared our study with previous experiments involving carboxylic-acid-stabilized nanosphere interaction with BSA.
Molecular Comparison Between Resistance Genes in Staphylococcus aureus Clinically Isolated from Cattle and Camels in Southern Egypt

| S. aureus is one of the most common organisms associated with infections among dairy animals with frequent and rapid development of antibiotic resistance. The presence of genes encoding aminoglycoside resistance tetracycline resistance, and beta-lactam resistance were detected by whole genome sequencing. Seventy-nine S. aureus clinical isolates were isolated from milk samples of dairy cattle and she-camels in Southern Egypt. The sequences of resistant genes extracted from the whole genome sequences of the bacterial chromosome that was done through shotgun sequencing, through phylogenetic analysis, all resistant genes sequences were arranged into two main clusters. The first clusters contain mecA genes, aminoglycosides, fusB gene as well as blaz gene except A11, and two reference genes (AJ302698 and AP003139). The second cluster contains mainly the tet(k) and tet(38) genes which are more similar to each other, in addition to mecA reference gene (AB512767) and two blaz reference genes (AJ302698 & AP003139). The phylogenic tree revealed that all resistant genes are more or less stable genes such as mecA, aminoglycosides, tet(k), tet(38), and fusB except blaz gene showing more variations. Molecular detection continues to be increased to establish antimicrobial resistance trends for S. aureus found in subclinical mastitis of dairy animals.
Development of a Real-Time Model-Prediction-Based Framework for Reset Controller Design

This paper addresses a real-time reset controller design based on the model prediction strategy for process control. Reset control design consists of two main steps: (1) base-system controller design and (2) reset law determination. The base system controller is designed according to the base (no reset) plant dynamics and the reset law is determined by an algebraic condition, which is checked throughout the time for controller state resetting. In this paper, based on the model prediction approach, a linear matrix inequalities (LMI)-based formulation is derived for designing the reset controller. When the reset condition is satisfied, the reset law is computed by solving an LMI optimization problem, and then base-system parameters and current controller states are suddenly changed to new values. This result is used in two examples; numerical simulations verify the efficiency of the proposed approach.
Identification of Nine Gibberellins from Young Fruit of Satsuma Mandarin (Citrus unshiu Marc.)

The application of gibberellins (GAs) to Citrus trees generally suppresses flower initiation, increases fruit set-ting, and delays fruit ripening.1} Kawarada and Sumiki2) identified gibberellin A1 (GAJ from water sprouts of Satsuma mandarin. Khalifah al.3) presented evidence for the occurrence of three GA-like substances, two of which behaved similarly to GAAand GA9in orange and lemon fruits. Recently, Poling and Maier4) reported on the identification of GAX17 19 20 29 and tentative identification of GA844 from vegetative shoots of navel orange trees.
Tumor Sidedness Could be a High-risk Factor in Patients with Stage II Colon Cancer

Background : The search for high-risk factors in stage II colon cancer (CC) is ongoing and several high-risk factors for stage II CC have been identified; however, the effects of tumor sidedness on prognosis is not clear. This study aims to determine whether tumor sidedness could be identified as another high-risk factor for stage II CC. Methods : We retrospectively analyzed 189 patients with stage II CC, following consecutive curative resection surgery performed between 2008 and 2014. We compared clinicopathological findings and long-term outcomes between the patients with right colonic cancer (RCC) and patients with left colonic cancer (LCC). Prognostic factors for survival were determined using univariate and Cox proportional regression analyses. Results : A total of 72 patients were diagnosed with RCC and 117 patients were diagnosed with LCC. Patients with RCC were significantly older (p < 0.001) than those with LCC, and the number of harvested lymph nodes (HLNs) was greater in the RCC group (RCC: 25 vs. LCC: 19; p = 0.003). The overall survival (OS) was notably worse in the RCC group than the OS in the LCC group (5 year survival rate—RCC: 81.3% vs. LCC: 90.4%; p = 0.025), whereas no significant difference was observed in disease-free survival (5 year survival rate—RCC: 74.8% vs. LCC: 83.4%; p = 0.065). Cox proportional regression analysis showed that tumor sidedness (hazard ratio (HR): 3.78, 95% confidence interval (CI): 1.61–8.85, p = 0.022), gender (HR: 3.27, 95% CI: 1.27–8.47, p = 0.014), and the number of HLNs (HR: 4.58, 95% CI: 1.95–10.74, p < 0.001) were independent prognostic factors for OS. Conclusion : Patients with a right-sided primary tumor location have more negative prognostic factors and worse long-term outcomes than those with a left-sided primary tumor location in stage II CC. Tumor sidedness is a high-risk factor in stage II CC patients.
Signaling Smartness: Smart Cities and Digital Art in Public Spaces

Informational urbanism is a new research area in information science. In this study, art history joins informational urbanism: Are digital artworks in public urban spaces recognized as essential assets of a smart city? We employed case study research, working with the example of the huge digital media façade of the Arthouse Graz as an artwork in a public space. In a mixed-methods approach, we asked passers-by and interviewed experts on Graz as a smart city and on the Arthouse’s role concerning the image of Graz as a smart city. The research found strong hints that indeed digital artworks with large screens or media façades at public spaces are parts of a city’s weak location factors as well as of the city’s urban structure and may symbolize the city’s smartness. A practical implication of this finding is that artists, computer and information scientists, city planners, and architects should include interactive contemporary digital art into city spaces in order to demonstrate the city’s way towards knowledge society
Sustain Wheat Production and Avoid Saline Water decline by using Stimulation Substances and Foliar Application of Micronutrients under North Sinai Soils Condition

To maximize the beneficial effect of using some stimulation substances (Potassium Fulvate and Yeast) along with foliar application of micronutrients on wheat crop productivity and properties of sandy soils under irrigation with saline ground water. Two field trials were conducted during two successive winter growing seasons of 2016/17and 2017/18 in Agricultural Experimental Research Station at Al-Arish, Agricultural Research Centre (ARC), Al-Arish Province, North Sinai Governorate, Egypt. The main treatments were Stimulants substants included four treatments (i. e. control, Potassium Fulvate (KFv), Yeast (Yst) and KFv+Yst) whereas the subplot treatments were micronutrients foliar application included three treatments (i.e. control, chelated form (Fe+Zn+Mn-EDTA) and mineral form (Fe+Zn+Mn-SO4). The treatments were layout in split plot design with three replicates. The results indicated that application of (KFv+Yst) with foliar application of micronutrients was the best treatment for vegetative growth traits i.e. fresh and dry weight (FW and DW), plant height (PH), chlorophyll content (Chl) and chemical constituents in above ground parts (N, P and K as macronutrients and Fe, Zn and Mn as Micronutrients) as well as grains yield, while the sodium (Na) content of grains was decreased. The highest values of soil available nutrients were recorded with the treatment of (KFv+Yst) and foliar application with micronutrients in the mineral form. Thus, it could be concluded that, the fertilization with potassium fulvate and yeast along with foliar application of micronutrients in mineral sulfate form was considered the most suitable treatment for obtaining the highest grains yield of wheat plants.
Ni–Pt Core–Shell Nanoparticles as Oxygen Reduction Electrocatalysts: Effect of Pt Shell Coverage

Core–shell nanoparticulate catalysts with a nonprecious metal core and a thin precious metal shell not only save precious metals but also could enhance the catalytic performance of precious metals through properly tuned strain and ligand effects. In this study, we show that, in addition to the nature and composition of core metals, the electrocatalytic properties of the precious metal shell can be tuned by varying its surface coverage. Carbon-supported Ni–Pt core–shell nanoparticle catalysts (Ni–Pt/C) with a series of Pt coverages are synthesized by depositing different amounts of Pt on Ni nanoparticles ca. 5 nm in size. It is found that Pt approximately forms an extended layer on Ni particles as its coverage does not exceed that required for a monolayer formation. The electrocatalytic properties of the Ni–Pt/C catalysts, such as the stripping potential for the oxygenated adsorbates, the activity for the oxygen reduction reaction (OPR), and the electrochemical stability under continuous potential cycling,.
Efficient Known-Sample Attack for Distance-Preserving Hashing Biometric Template Protection Schemes

The rapid deployment of biometric authentication systems raises concern over user privacy and security. A biometric template protection scheme emerges as a solution to protect individual biometric templates stored in a database. Among all available protection schemes, a template protection scheme that relies on distance-preserving hashing has received much attention due to its simplicity and efficiency in offering privacy protection while archiving decent authentication performance. In this work, we introduce an efficient attack called known sample attack and demonstrate that most state-of-art template protection schemes that utilize distance-preserving hashing can be compromised in practice (within few seconds), especially when the output is significantly smaller than the original input sample size. These findings further motivated our subsequent work in proposing a secure authentication mechanism to resist such an attack with proper study over the distribution of the input samples. Furthermore, we conducted revocability, unlinkability analysis to demonstrate the satisfactory of general biometric template protection requirements; and showed the resistance of various security and privacy attacks, i.e., false acceptance attack, and attack via record multiplicity.
