Shortchanging complexity: Discourse, distortions, and diversity policy in the age of neoliberalism
Authors: Arce-Trigatti Andrea , Anderson Ashlee 
Published: July 2019

With this paper we explore the practical materialization of select diversity policies in the United States via an analysis of their implementation at different institutional levels. Specifically, using a cultural studies framework that is guided by Stuart Hall’s (1993) concept of distortions, we investigate how discursive conceptualizations of diversity have been translated into educational policy at the federal and state levels. We contend that the complexity of diversity is often inconsistent with existing neoliberal reform trends that embrace standardization and accountability, making meaningful practical applications exponentially more challenging (Manna, 2011; Wong, 2008). Finally, we look to how these analyses might inform future iterations of diversity policy in a time where rapid changes in education policy and characteristically partisan political agendas have become the norm.
Molecular structure-property relations controlling mashing performance of amylases as a function of barley grain size
Authors: Quek Wei Ping , Yu Wenwen , Fox Glen P. , Gilbert Robert G. 
Published: July 2019

Abstract
In brewing, amylases are key enzymes in hydrolyzing barley starch to sugars, which are utilized in fermentation to produce ethanol. Starch fermentation depends on sugars produced by amylases and starch molecular structure, both of which vary with barley grain size. Grain size is a major industrial specification for selecting barley for brewing. An in-depth study is given of how enzyme activity and starch structure vary with grain size, the impact of these factors on fermentable sugar production, and the underlying mechanisms. Micro-malting and mashing experiments were based on commercial methodologies. Starch molecular structural parameters were obtained using size-exclusion chromatography, and fitted using biosynthesis-based models. Correlation analysis using the resulting parameters showed larger grain sizes contained fewer long amylopectin chains, higher amylase activities and soluble protein level. Medium grain sizes released most sugars during mashing, because of higher starch utilization from the action of amylases, and shorter amylose chains. As starch is the substrate for amylase-driven fermentable sugars production, measuring its structure should be a prime indication for mashing performance, and should be used as an industry specification when selecting barley grains for brewing.
Design of Artificial Sun-Synchronous Orbits with Main Zonal Harmonics and Solar Radiation Pressure Using Continuous Low-Thrust Control Strategies
Authors: Masoud Akram , Rahoma Walid Ali , Khattab Elamira Hend , El-Salam Fawzy Ahmed Abd 
Published: July 2019

Abstract
Artificial sun-synchronous orbits are suitable for remote sensing satellites and useful in giving accurate surface mapping. To design such orbits accurately with arbitrary orbital elements, three control strategies are provided with the consideration of main zonal harmonics up to J
4 and solar radiation pressure (SRP). In this paper, the continuous variable low-thrust control is used as a way to achieve these artificial orbits and given by electric propulsions rather than chemical engines to enlarge lifespan of the spacecraft. The normal continuous low-thrust control is used to illustrate the control strategies. Furthermore, formulas for refinement of normal control thrusts are applied to overcome errors due to approximations. The results of the simulation show that the control strategies explained in this paper can realize sun-synchronous orbits with arbitrary orbital parameters without side effects and the effect of solar radiation pressure is very small relative to main zonal harmonics. A new technique is suggested, ASSOT-3, to minimize fuel consumption within one orbital period more than others. This technique is based on computing the root mean square of the rate of ascending node longitude instead of the average.
Reasoning About ‘When’ Instead of ‘What’: Collusive Equilibria with Stochastic Timing in Repeated Oligopoly
Authors: Grana Justin , Bono James , Wolpert David 
Published: July 2019

Abstract
We analyze a continuous time game of Bertrand competition with private monitoring that includes asynchronous signals and asynchronous actions. Unlike existing models where firms observe a signal that is imperfectly correlated with demand parameters and firms’ prices, we assume firms observe demand and prices perfectly but at times governed by independent Poisson processes. The signals only reveal information at the instant they are observed and do not contain information about past actions or states of demand. This implies that any firm’s price change will go undetected for some time or may never be detected. Firms are also allowed to engage in costless but unverifiable cheap talk. The model focuses on the strategic considerations that arise when firms reason about then timing of the signals rather than the content. We show that standard Nash reversion arguments can enforce collusion and truthful communication when signals are asynchronous and signals only reveal information about the current state of the world and do not reveal information about past states or actions. Through comparative statics, we disentangle how parameters that govern the timing of events and signals interact to either facilitate or preclude collusion. Finally, we extend the model to show that firms may collude not only to avoid Nash reversion but to prevent opposing firms from believing demand has dropped and thus lowering their price.

Published: July 2019

Abstract
The aim of this study was the quantitative evaluation of gastrointestinal cancer cell motility and 5-aminolevulinic acid (5-ALA)-induced fluorescence in vitro using mathematical morphology and structural analysis methods. The results of our study showed that MKN28 cells derived from the lymph node have the highest motility compared with AGS or HCT116 cells derived from primary tumors. Regions of single cells were characterized as most moving, and “tightly packed” cell colonies as nearly immobile. We determined the reduction of cell motility in late passage compared to early passage. Application of 5-ALA caused fluorescence in all investigated cells, and the fluorescence was different with regard to the cell type and application time. We observed higher fluorescence in MKN28 cells. Comprehensive image analysis did not reveal any statistically significant difference in fluorescence intensity between “tightly packed” cell regions, where nearly no motility was registered and loosely distributed cells, where the highest cell motility was registered. In conclusions, our study revealed that MKN28 cells derived from the lymph node have higher motility and 5-ALA-induced fluorescence than AGS or HCT116 derived from primary tumors. Moreover, image analysis based on a large amount of processed data is an important tool to study these tumor cell properties.
Fast 0/1-h algorithm for detection of NSTEMI: are current high-sensitivity cardiac troponin assays fit for purpose? An EQA-based evaluation
Authors: van der Hagen Eline A.E. , Cobbaert Christa M. , Meijer Ron , Thelen Marc H.M. 
Published: July 2019

Abstract

Background
High-sensitivity cardiac troponin T/I (hs-cTnT/I) assays have improved analytical sensitivity for the detection of myocardial infarction (MI). To gain clinical specificity and sensitivity, interpretation of changes in cTn concentrations over time is crucial. The 2015 ESC NSTEMI guideline defines absolute delta values as additional rule-in and rule-out criteria for MI. A critical assumption for application of this rule is that total analytical imprecision within the delta period, including inter-instrument bias, is comparable to analytical imprecision in the validation studies.

Methods
Data from the Dutch External Quality Assessment Scheme (EQAS) were used to calculate inter-instrument bias and estimate imprecision for the measuring range where the proposed delta values are relevant: for Roche Elecsys hs-cTnT, 5–52 and 5–12 ng/L; for Abbott Architect hs-cTnI, 2–52 and 2–5 ng/L for rule-in and rule-out, respectively.

Results
For Elecsys, the median inter-instrument bias is 0.3 ng/L (n = 33 laboratories), resulting in reference change values (RCVs) of 3.0 and 1.7 ng/L, respectively, for rule-in and rule-out with imprecision as claimed by the manufacturer. With RCVs smaller than the guideline’s delta thresholds, 100% of the laboratories have adequate specifications. RCVs for rule-in/rule-out increased to 4.6 ng/L/2.5 ng/L, respectively, with individual imprecisions as estimated from EQA data, resulting in 64% and 82% of laboratories with adequate specifications. For Architect, 40% of instruments (n = 10) might falsely qualify the result as clinically relevant; hence, inter-instrument bias could not be determined.

Conclusions
We advise laboratories that use the fast 0/1-h algorithm to introduce stringent internal quality procedures at the relevant/low concentration level, especially when multiple analyzers are randomly used.

Published: July 2019

Abstract

Background
Total human chorionic gonadotropin (hCGt) tumour marker testing is regarded as an “off label” application for most commercial methods. We compared four assays in patients with a hCGt tumour marker request. We hypothesised that regression slopes would be altered and that outliers would be more common with tumour marker than with pregnancy samples if the detection of malignancy associated hCG molecular forms differed amongst assays. Further such systematic differences would be obvious and large enough to change clinical management decisions.

Results
We measured hCGt in 390 samples from 137 females and 253 males with a tumour marker request and 208 pregnancy controls with the following methods: Access Total βhCG, Architect Total-βhCG, Cobas hCG + β and Immulite HCG. The between method regressions determined on tumour marker and pregnancy samples were not significantly different. The outlier rates were similar for male and female tumour marker and the pregnancy groups: 1.6% (95% confidence interval [CI] 0%–3.1%), 2.2% (95% CI 0%–4.7%) and 2.9% (95% CI 0.6%–5.2%). The outliers were randomly distributed amongst the methods and we were confident that they would not adversely influence clinical decisions.

Conclusions
The hCGt results were clinically equivalent with no systematic difference amongst the four assays.
Construal vs. redundancy: Russian aspect in context
Authors: Janda Laura A. , Reynolds Robert J. 
Published: July 2019

AbstractThe relationship between construal and redundancy has not been previously explored empirically. Russian aspect allows speakers to construe situations as either Perfective or Imperfective, but it is not clear to what extent aspect is determined by context and therefore redundant. We investigate the relationship between redundancy and open construal by surveying 501 native Russian speakers who rated the acceptability of both Perfective and Imperfective verb forms in complete extensive authentic contexts. We find that aspect is largely redundant in 81% of uses, and in 17% of contexts aspect is relatively open to construal. We contend that anchoring in redundant contexts likely facilitates the independence of construal in contexts with less redundancy. However further research is needed to discover what makes contexts redundant since known cues for aspect are absent in the majority of such contexts. Native speakers are fairly consistent in giving the original aspect high ratings, but less consistent in rating the non-original aspect, indicating potential problems in testing the reactions of speakers to non-authentic data.
“Categorically Grotesque: Ballard, Bodies and Genre in Crash”
Authors: Kavanagh Ciarán 
Published: July 2019

Abstract
Crash’s philosophical and aesthetic focus on the wounded body has led to it being described by many of its readers as repulsive, disgusting, nauseating, and in other similarly visceral vocabulary. It has also, however, been praised in the highest terms for its perceived exploration and criticism of postmodernity, technofetishism, and the advertising industry, along with its estrangement of society’s acceptance of the automobile age and its mutilation of our landscape, psyche and bodies. Critics of Crash who wish to portray the novel positively frequently appear under pressure to defang this aspect of it, attempting to domesticate Crash’s troubling‘low’ matter by the aforementioned ‘higher‘ aesthetic or moral cause. Crash, however, eludes this manner of simplification; the novel cannot be adequately analysed by shirking from its embodied effects. A chimaeric fusion of opposing experiential and interpretive catalysts, Crash refuses to be statically categorised.
Lessons in clinical reasoning – pitfalls, myths, and pearls: a case of chest pain and shortness of breath
Authors: Walker McCall , Warburton Karen M. , Rencic Joseph , Parsons Andrew S. 
Published: July 2019

Abstract

Background
Defects in human cognition commonly result in clinical reasoning failures that can lead to diagnostic errors. A metacognitive structured reflection on what clinical findings fit and/or do not fit with likely and “can’t miss” diagnoses may reduce such errors.

Case presentation
A 57-year-old man was sent to the emergency department from clinic with chest pain, severe shortness of breath, weakness, and cold sweats. Further investigation revealed multiple risk factors for coronary artery disease, sudden onset of exertional dyspnea, and chest pain that incompletely resolved with rest, mild tachycardia and hypoxia, an abnormal electrocardiogram (ECG), elevated serum cardiac biomarkers, and elevated B-type natriuretic peptide (BNP) in the absence of left-sided heart failure. He was treated for acute coronary syndrome (ACS), discharged, and quickly returned with worsening symptoms that eventually led to a diagnosis of submassive pulmonary embolism (PE).

Conclusions
Through integrated commentary on the diagnostic reasoning process from clinical reasoning experts at two institutions, this case underscores the importance of frequent assessment of fit along with explicit explanation of dissonant features in order to avoid premature closure and diagnostic error. A fishbone diagram is provided to visually demonstrate the major factors that contributed to the diagnostic error. A case discussant describes the importance of diagnostic schema as an analytic reasoning strategy to assist in the creation of a differential diagnosis, problem representation to summarize updated findings, a Popperian analytic approach of attempting to falsify less-likely hypotheses, and matching pertinent positives and negatives to previously learned illness scripts. Finally, this case provides clinical teaching points in addition to a pitfall, myth, and pearl specific to premature closure.
Modifying potato starch by glutaraldehyde and MgCl2 for developing an economical and environment-friendly electrolyte system
Authors: Komal Baby , Yadav Madhavi , Kumar Manindra , Tiwari Tuhina , Srivastava Neelam 
Published: July 2019

AbstractBiodegradable polymer electrolyte systems are the most sought over option for cheap and energy efficient storage devices. Present paper discusses the results of potato starch + MgCl2system which satisfy the technical and economic criteria to become a potential candidate for future electrolyte systems. The developed system has high ionic conductivity (~3.43 × 10-2S/cm), low relaxation time (75 μs) and wide electrochemical stability window (ESW ~4.6 V). The phase angle approaches -79° and maintains its value for 10 Hz to 1 kHz frequency range. The prepared material is a free standing film which can be bended and twisted up to 90°, which makes it suitable for flexible electrochemical device fabrication. The equivalent series resistance (ESR) is quite low (3.41 Ω) and self-resonance frequency below which energy can be efficiently stored is approximately 0.1 MHz. Hence the present study reports an economical, easy to handle and environment friendly electrolyte suitable for electrochemical device fabrication.
Additional Extension of the Mathematical Model for BCG Immunotherapy of Bladder Cancer and Its Validation by Auxiliary Tool
Authors: Guzev Ekaterina , Halachmi Sarel , Bunimovich-Mendrazitsky Svetlana 
Published: July 2019

Abstract
Immunotherapy with bacillus Calmette–Guérin (BCG) is a classic treatment for superficial bladder cancer. Although BCG instillation is a well-established protocol, some patients do not respond to this treatment. To model improvement of this protocol, Bunimovich-Mendrazitsky (B-M) et al. provided a platform for in silico testing of modified protocols of BCG instillation and combination with IL-2. The purpose of this work is to improve and further develop this BCG model describing the tumor–immune interactions occurring in the bladder in response to BCG and IL-2 therapies, based on novel clinical data.
To validate this BCG model, we used the results of BCG treatment of 10 patients with bladder cancer 3-5 years ago. Individual data for each patient was entered to simulate the model. As a result, a treatment protocol was obtained which coincided with the protocol assigned by the doctor. In addition, cancer cell growth graphs were obtained from the model simulations, which coincided with the clinical conclusions of the patient’s treatment outcome. Moreover, the program provides a more optimal treatment protocol for each patient.
We show that calculated protocols from the model can prevent excess side effects of immunotherapy and even of unnecessary death for some patients, informing the clinical potential of our model.
Fenugreek seed extract ameliorates cognitive deficits in streptozotocin-induced diabetic rats
Authors: Kodumuri Praveen K. , Thomas Christofer , Jetti Raghu , Pandey Anil Kumar 
Published: July 2019

Abstract

Background
Natural medicinal plants have been the focus of current research for developing neuroprotective agents to be used in the diabetes-linked cognitive dysfunction. Trigonella foenum-graecum seeds (known as fenugreek, methi in Hindi), is a well-known traditional medicinal herb and possesses anti-diabetic, anti-oxidant, and anti-inflammatory properties.

Purpose
This study was undertaken to explore the ameliorative effects of T. foenum-graecum seed extract on diabetes-induced cognitive dysfunction.

Methods
Experimental diabetes was induced by administering a single dose of streptozotocin (60 mg/kg) through intraperitoneal dose. Cognitive function was assessed using a T-maze and the Morris water maze. Lipid peroxidation levels and oxidative stress in the hippocampus was measured. Quantification of hippocampal CA1 and CA3 regions was done using cresyl violet stain.

Results
Diabetic rats demonstrated learning and memory impairment, which was evident from poor performance in behavioral tasks, i.e. T-maze and Morris water maze tasks. Learning and memory impairment in diabetic animals is associated with increased blood glucose levels, increased oxidative stress in the hippocampus and decreased number of neurons in the CA1 and CA3 regions of the hippocampus. The diabetic rats administered with T. foenum-graecum showed improved performance in behavioral tasks, and these changes were associated with decreased blood glucose levels, decreased oxidative stress in the hippocampus, and decreased neuronal loss from the CA1 and CA3 regions of the hippocampus.

Conclusion
In conclusion, administration of T. foenum-graecum seed extract ameliorates diabetes-linked cognitive dysfunction in rats by decreasing blood glucose levels, reducing lipid peroxidation and oxidative stress in the hippocampus, and preventing neuronal loss from the hippocampus.
Enhancing Goldreich, Goldwasser and Halevi’s scheme with intersecting lattices
Authors: Sipasseuth Arnaud , Plantard Thomas , Susilo Willy 
Published: July 2019

Abstract
We present a technique to enhance the security of the Goldreich, Goldwasser and Halevi (GGH) scheme.
The security of GGH has practically been broken by lattice reduction techniques.
Those attacks are successful due to the structure of the basis used in the secret key.
In this work, we aim to present a new technique to alleviate this problem by modifying the public key which hides the structure of the corresponding private key.
We intersect the initial lattice with a random one while keeping the initial lattice as our secret key and use the corresponding result of the intersection as the public key.
We show sufficient evidence that this technique will make GGH implementations secure against the aforementioned attacks.

The retraction of certain banach right modules associated to a character
Authors: Dashti Mahshid , Renani Sima Soltani 
Published: July 2019

Abstract
Let 𝓐 be a Banach algebra and let 𝓜 be a unital Banach algebra. For a homomorphism Φ from 𝓐 into 𝓜, we consider 𝓜 as a Banach right 𝓐-module and investigate when 𝓜 is a retract of 𝓐 with respect to Φ. We also give characterizations of admitting vector-valued invariant Φ-means in terms of projectivity and injectivity. Finally, we apply these results to abstract Segal algebras.
Hilbert algebras with supremum generated by finite chains
Authors: Gaitán Hernando 
Published: July 2019

Abstract
Based on the work of A. Monteiro, A. Torrens, and D. Buşneag, in this paper we point out that the dual space of Hilbert algebras with supremum generated by chains depends, modulo the dual space of a Hilbert algebra with supremum defined by S. Celani an D. Montangie, exclusively, on the order carried out by the topological space. We use such a characterization to prove that a bounded Hilbert algebra generated by chains is determined by the monoid of its endomorphisms.
