description: Spray characterization has been an issue for process and product characterization for decades. Because of this, a convolutional neuronal network was developed to determine the droplet size from spray images. The images were taken using a digital camera, a light source, and a dark room. These were subsequently employed to design and train a convolutional neuronal network using open-source software packages and a desktop computer. The accuracy of the network droplet size determinations was checked with additional, independent images. The median drop size was assessed with a high accuracy of more than 99.8 % as the mean spray performance indicator. Additionally, the droplet size distribution measurements from the neural network method deviated from those from the reference method (laser diffraction) by less than 1.5 %. Convolutional neuronal networks can be applied to determine the spray performance using spray cone images. This approach could be useful for multiple applications.

Publisher: name: London South Bank University
Year: 1981

description: A study of the parameters such as pH, glucose concentration and residual nitrogen content influencing the build up of 5'-monophosphonucleotides of Saccharomyces cerevisiae "No. 56" has been carried out. An investigation into cell size, budding stage and release of cytoplasmic constituents of Saccharomyces cerevisiae Distillers M during its replenishment in various media was carried out. Results have shown that maximum cell size occurred after a defined period (2 hours) at which time budding had commenced and relatively high concentrations of 5'-monophosphonucleotides were found. Release (shock excretion) of cytoplasmic constituents was investigated as a function of time using glucose. An initial 30 minute starvation of the yeast cells following by a 90 minutes shock excretion, was found to be the optimum time for the release of 5'-monophospho nucleotides. A sucrose fatty acid ester used as a shock excretion agent, was found to be more efficient than glucose, and ensured retention of a high viability of the yeast cells when used in a 20 litre continuous tower fermenter System. Using this equipment a continuous process, has been developed for the repeated release and recovery of (iv) cytoplasmic constituents rich in 5'-monophosphonucleo tides from yeast cells, which comprises: 1) contacting the yeast cells with a solution of a sucrose fatty acid ester. 2) separating the yeast cells from the released cytoplasmic constituents. 3) supplying the yeast cells with fresh medium to allow restoration of the level of 5'-monophospho nucleotides to the level required for shock excretion as in 1). The work has resulted in the development of a high-performance liquid chromatographic method for the analysis of 5'-monophosphonucleotides, AMP, CMP, TMP, IMP, UMP and XMP in the cytoplasmic constituents of the yeast cells. Organoleptic comparison of the freeze-dried cytoplasmic constituents produced during this study with commercially available material has been used.

description: The RRAM-based neuromorphic computing system has amassed explosive interests for its superior data processing capability and energy efficiency than traditional architectures, and thus being widely used in many data-centric applications. The reliability and security issues of the NCS therefore become an essential problem. In this paper, we systematically investigated the adversarial threats to the RRAM-based NCS and observed that the RRAM hardware feature can be leveraged to strengthen the attack effect, which has not been granted sufficient attention by previous algorithmic attack methods. Thus, we proposed two types of hardware-aware attack methods with respect to different attack scenarios and objectives. The first is adversarial attack, VADER, which perturbs the input samples to mislead the prediction of neural networks. The second is fault injection attack, EFI, which perturbs the network parameter space such that a specified sample will be classified to a target label, while maintaining the prediction accuracy on other samples. Both attack methods leverage the RRAM properties to improve the performance compared with the conventional attack methods. Experimental results show that our hardware-aware attack methods can achieve nearly 100% attack success rate with extremely low operational cost, while maintaining the attack stealthiness.

description: The U.S. government recently implemented rules for awarding compensation to individuals with cancer who were exposed to ionizing radiation while working in the nuclear weapons complex. Under these rules, chronic lymphocytic leukemia (CLL) is considered to be a nonradiogenic form of cancer. In other words, workers who develop CLL automatically have their compensation claim rejected because the compensation rules hold that the risk of radiation-induced CLL is zero. In this article we review molecular, clinical, and epidemiologic evidence regarding the radiogenicity of CLL. We note that current understanding of radiation-induced tumorigenesis and the etiology of lymphatic neoplasia provides a strong mechanistic basis for expecting that ionizing radiation exposure increases CLL risk. The clinical characteristics of CLL, including prolonged latency and morbidity periods and a low case fatality rate, make it relatively difficult to evaluate associations between ionizing radiation and CLL risk via epidemiologic methods. The epidemiologic evidence of association between external exposure to ionizing radiation and CLL is weak. However, epidemiologic findings are consistent with a hypothesis of elevated CLL mortality risk after a latency and morbidity period that spans several decades. Our findings in this review suggest that there is not a persuasive basis for the conclusion that CLL is a nonradiogenic form of cancer.

It is shown that if spacetimes have non-compact Cauchy surfaces, then the groups are subgroups of that of two-dimensional Minkowski spacetime, and if spacetimes have compact Cauchy surfaces, then the groups are subgroups of that of two-dimensional Einstein's static universe.

description: Soluble particulate matter (PM) components (e.g., metals) have the potential to be absorbed into the bloodstream and transported to the heart where they might induce the expression of inflammatory cytokines and remodel electrical properties. We exposed cultured rat ventricular myocytes to similar concentrations of two metals [zinc (Zn) and vanadium (V)] found commonly in PM and measured changes in spontaneous beat rate. We found statistically significant reductions in spontaneous beat rate after both short-term (4-hr) and long-term (24-hr) exposures, with a more substantial effect seen with Zn. We also measured the expression of genes associated with inflammation and a number of sarcolemmal proteins associated with electrical impulse conduction. Exposure to Zn or V (6.25-50 microM) for 6 hr produced significant increases in IL-6, IL-1 alpha, heat shock protein 70, and connexin 43 (Cx43). After 24 hr exposure, Zn induced significant changes in the gene expression of Kv4.2 and KvLQt (potassium channel proteins), the alpha 1 subunit of the L-type calcium channel, and Cx43, as well as IL-6 and IL-1 alpha. In contrast, V produced a greater effect on Cx43 and affected only one ion channel (KvLQT1). These results show that exposure of rat cardiac myocytes to noncytotoxic concentrations of Zn and V alter spontaneous beat rate as well as the expression of ion channels and sarcolemmal proteins relevant to electrical remodeling and slowing of spontaneous beat rate, with Zn producing a more profound effect. As such, these data suggest that the cardiac effects of PM are largely determined by the relative metal composition of particles.
An Architecture of Intimacy: How Technology Reimagines Intimacy and Relational Communication

description: This qualitative study explores how mobile media transforms our collective notion of intimacy and the rituals of connecting with others through communication. Using Bourdieu’s field theory and interpersonal communication frameworks of relational development and maintenance, this work answers three research questions: (1) What forms of intimacy are afforded by communication technologies that facilitate mobility? (2) How do individuals reimagine these forms of intimacy within their habitus of relational norms? (3) How do ambient, always-on, technologies enable individuals to create shared spaces? To answer these questions, I integrated semi-structured interviews with an adapted artifact analysis to investigate how people define intimacy and understand these practices in a mediated environment. In total, 86 interviews were conducted with people who were 19-67-year-olds between June and December 2020. Results reveal four primary forms of intimacy afforded by mobile communication technologies: experiential-intimacy, imprinted-intimacy, cerebral-intimacy, and mediated-physical-intimacy. Each of these illustrates different tiers of intimacy that are significant in mediated relationships and encouraged by mobile media. These forms of intimacy materialize through a person’s habitus of relational norms, or what this study refers to as the imagined habitus. The imagined habitus becomes an anchor for how intimacy is continuously and concurrently developed, preserved, and remixed through media. Overall, the results highlight how intimacy is fluid, something that is subjectively defined and experienced through different platforms as we try and give it shape. As we live in media, technology starts to bend the spatiotemporal boundaries of relational life. It is here where intimacy emerges, where it can be reimagined and reproduced between people as they communicate. Yes, intimacy is associated with closeness in a relationship. However, intimacy can also be best understood as a relational process conceptualized by types, experienced through different avenues that become a performance, and arise in new forms when we think about the place of technology in relationships. Depending on what tools we have at hand, who we are as individuals, our visions of intimacy, and our experiences in relationships now and in the past, we use technology in formulaic and new ways to build a space where intimacy can live.

description: An infinite urn scheme is defined by a probability mass function $(p_j)_{j\geq1}$ over positive integers. A random allocation consists of a sample of $N$ independent drawings according to this probability distribution where $N$ may be deterministic or Poisson-distributed. This paper is concerned with occupancy counts, that is with the number of symbols with $r$ or at least $r$ occurrences in the sample, and with the missing mass that is the total probability of all symbols that do not occur in the sample. Without any further assumption on the sampling distribution, these random quantities are shown to satisfy Bernstein-type concentration inequalities. The variance factors in these concentration inequalities are shown to be tight if the sampling distribution satisfies a regular variation property. This regular variation property reads as follows. Let the number of symbols with probability larger than $x$ be $\vecν(x)=|\{j:p_j\geq x\}|$. In a regularly varying urn scheme, $\vecν$ satisfies $\lim_{τ\rightarrow0}\vecν(τx)/\vecν(τ)=x^{-α}$ for $α\in[0,1]$ and the variance of the number of distinct symbols in a sample tends to infinity as the sample size tends to infinity. Among other applications, these concentration inequalities allow us to derive tight confidence intervals for the Good--Turing estimator of the missing mass.

description: Global gene expression profiling has demonstrated that the predominant cellular response to a range of toxicants is a general stress response. This stereotyped environmental stress response commonly includes repression of protein synthesis and cell-cycle–regulated genes and induction of DNA damage and oxidative stress–responsive genes. Our laboratory recently characterized the general stress response of breast cell lines derived from basal-like and luminal epithelium after treatment with doxorubicin (DOX) or 5-fluorouracil (5FU) and showed that each cell type has a distinct response. However, we expected that some of the expression changes induced by DOX and 5FU would be unique to each compound and might reflect the underlying mechanisms of action of these agents. Therefore, we employed supervised analyses (significance analysis of microarrays) to identify genes that showed differential expression between DOX-treated and 5FU-treated cell lines. We then used cross-validation analyses and identified genes that afforded high predictive accuracy in classifying samples into the two treatment classes. To test whether these gene lists had good predictive accuracy in an independent data set, we treated our panel of cell lines with etoposide, a compound mechanistically similar to DOX. We demonstrated that using expression patterns of 100 genes we were able to obtain 100% predictive accuracy in classifying the etoposide samples as being more similar in expression to DOX-treated than to 5FU-treated samples. These analyses also showed that toxicant-specific gene expression patterns, similar to general stress responses, vary according to cell type.

description: Fatal case of co-infection with yellow fever virus and SARS-CoV2 during the 2020 Covid-19 pandemic in French Guiana

The yellow fever virus (YFV), recently renamed Orthoflavivirus flavi, is an arbovirus of the Flaviviridae family and Orthoflavivirus genus endemic in South America and Tropical Africa. Brazil experienced an epidemic of unprecedented magnitude between 2016 and 2018. The resurgence of new cases in French Guiana in recent years has rekindled interest in the disease. In December 2019, the global pandemic of Covid-19 began and rapidly reached South America. The first cases were reported in French Guiana in March 2020. Many tropical diseases circulate in the region and the possibility of co-infections is therefore high. Here, we report the first case of YF virus-SARS-CoV2 co-infection in a 14-year-old French Amerindian boy who died within nine days. He had received a single dose of YF vaccine in childhood.

Cas fatal de co-infection par le virus de la fièvre jaune et le SARS-CoV2 pendant la pandémie de Covid-19 de 2020 en Guyane

Le virus de la fièvre jaune (VFJ) récemment renommé Orthoflavivirus flavi est un arbovirus de la famille des Flaviviridae et du genre Orthoflavivirus endémique en Amérique du Sud et en Afrique tropicale. En Amérique latine, le Brésil a connu une épidémie d’une ampleur inégalée entre 2016 et 2018. La résurgence de nouveaux cas en Guyane ces dernières années a ravivé l’intérêt pour la maladie. En décembre 2019, la pandémie mondiale de Covid-19 a débuté et a rapidement atteint l'Amérique du Sud. Les premiers cas ont été recensés en Guyane en mars 2020. De nombreuses maladies tropicales circulent dans la région et augmentent ainsi la possibilité d'observer des co-infections. Nous rapportons ici le premier cas de co-infection VFJ-SARS-CoV2 chez un jeune Français amérindien de 14 ans vivant sur le Haut-Maroni, dont l’issue a été fatale en neuf jours. Il a reçu une dose unique de vaccin antiamaril dans l’enfance.

description: We have previously documented the presence of progesterone and androstenedione in the water column and bottom sediments of the Fenholloway River, Taylor County, Florida. This river receives paper mill effluent and contains masculinized female mosquitofish. We hypothesized that plant sterols (e.g., β-sitosterol) derived from the pulping of pine trees are transformed by bacteria into progesterone and subsequently into 17α-hydroxyprogesterone, androstenedione, and other androgens. In this study, we demonstrate that these same androgens can be produced in vitro from the bacterium Mycobacterium smegmatis. In a second part to this study, we reextracted and reanalyzed the sediment from the Fenholloway River and verified the presence of androstadienedione, a Δ1 steroid with androgen activity.

description: More than half the world’s human population lives within 100 km of the coast, and that number is expected to increase by 25% over the next two decades. Consequently, coastal ecosystems are at serious risk. Larger coastal populations and increasing development have led to increased loading of toxic substances, nutrients and pathogens with subsequent algal blooms, hypoxia, beach closures, and damage to coastal fisheries. Recent climate change has led to the rise in sea level with loss of coastal wetlands and saltwater intrusion into coastal aquifers. Coastal resources have traditionally been monitored on a stressor-by-stressor basis such as for nutrient loading or dissolved oxygen. To fully measure the complexities of coastal systems, we must develop a new set of ecologic indicators that span the realm of biological organization from genetic markers to entire ecosystems and are broadly applicable across geographic regions while integrating stressor types. We briefly review recent developments in ecologic indicators and emphasize the need for improvements in understanding of stress–response relationships, contributions of multiple stressors, assessments over different spatial and temporal scales, and reference conditions. We provide two examples of ecologic indicators that can improve our understanding of these inherent problems: a) the use of photopigments as indicators of the interactive effects of nutrients and hydrology, and b) biological community approaches that use multiple taxa to detect effects on ecosystem structure and function. These indicators are essential to measure the condition of coastal resources, to diagnose stressors, to communicate change to the public, and ultimately to protect human health and the quality of the coastal environment.

description: We consider an action of the real line on a C*-algebra for which there is a centre-valued invariant trace. We define a family of Toeplitz operators with symbols in the original algebra. When the symbol is invertible, the Toeplitz operator is Fredholm in an appropriate sense, and we give a formula for the index using a notion of centre-valued winding number defined using the trace. The results and techniques generalise previous results of the authors for scalar-valued traces.

description: We study exact confidence intervals and two-sided hypothesis tests for univariate parameters of stochastically increasing discrete distributions, such as the binomial and Poisson distributions. It is shown that several popular methods for constructing short intervals lack strict nestedness, meaning that accepting a lower confidence level not always will lead to a shorter confidence interval. These intervals correspond to a class of tests that are shown to assign differing $p$-values to indistinguishable models. Finally, we show that among strictly nested intervals, fiducial intervals, including the Clopper-Pearson interval for a binomial proportion and the Garwood interval for a Poisson mean, are optimal.

description: To assess potential effects of human DDT [1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane] exposure, we evaluated the reproductive history of 2,033 workers in the antimalaria campaign of Mexico. Data on occupational exposure to DDT and reproductive outcomes were gathered through a questionnaire, and workers provided information about 9,187 pregnancies. We estimated paternal exposure to DDT before each pregnancy using three approaches: a) a dichotomous indicator for pregnancies before and after exposure began, b) a qualitative index of four exposure categories, and c) an estimation of the DDT metabolite DDE [1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene] accumulated in fat. To assess associations, we used logistic regression models that accounted for correlated observations and adjusted for parents' age at each child's birth, exposure to other pesticides, exposure to chemical substances in other employment, smoking, and alcohol consumption. The odds ratio for birth defects comparing pregnancies after and before the first exposure was 3.77 [95% confidence interval (95% CI), 1.19-9.52]. Compared with the lowest quartile of estimated DDE in fat, the ORs were 2.48 (95% CI, 0.75-8.11), 4.15 (95% CI, 1.38-12.46), and 3.76 (95% CI, 1.23-11.44) for quartiles 2, 3, and 4, equivalent to p,p -DDE in fat of 50, 82, and 298 microg/g fat, respectively. No significant association was found for spontaneous abortion or sex ratio. We found an increased risk of birth defects associated with high occupational exposure to DDT in this group of workers. The significance of this association at lower exposure levels found in the general population remains uncertain.

description: In this paper we present a heuristic method to provide individual explanations for those elements in a dataset (data points) which are wrongly predicted by a given classifier. Since the general case is too difficult, in the present work we focus on faulty data from an underfitted model. First, we project the faulty data into a hand-crafted, and thus human readable, intermediate representation (meta-representation, profile vectors), with the aim of separating the two main causes of miss-classification: the classifier is not strong enough, or the data point belongs to an area of the input space where classes are not separable. Second, in the space of these profile vectors, we present a method to fit a meta-classifier (decision tree) and express its output as a set of interpretable (human readable) explanation rules, which leads to several target diagnosis labels: data point is either correctly classified, or faulty due to a too weak model, or faulty due to mixed (overlapped) classes in the input space. Experimental results on several real datasets show more than 80% diagnosis label accuracy and confirm that the proposed intermediate representation allows to achieve a high degree of invariance with respect to the classifier used in the input space and to the dataset being classified, i.e. we can learn the metaclassifier on a dataset with a given classifier and successfully predict diagnosis labels for a different dataset or classifier (or both).

description: Exposure to excessive vanadium occurs in some occupations and with consumption of some dietary regimens for weight reduction and body building. Because vanadium is vasoactive, individuals exposed to excessive vanadium may develop adverse vascular effects. We have previously shown that vanadyl sulfate causes acute pulmonary vasoconstriction, which could be attributed in part to inhibition of nitric oxide production. In the present study we investigated whether NO inhibition was related to phosphorylation of endothelial nitric oxide synthase (eNOS). VOSO4 produced dose-dependent constriction of pulmonary arteries in isolated perfused lungs and pulmonary arterial rings and a right shift of the acetylcholine-dependent vasorelaxation curve. VOSO4 inhibited constitutive as well as A23187-stimulated NO production. Constitutive NO inhibition was accompanied by increased Thr495 (threonine at codon 495) phosphorylation of eNOS, which would inhibit eNOS activity. Thr495 phosphorylation of eNOS and inhibition of NO were partially reversed by pretreatment with calphostin C, a protein kinase C (PKC) inhibitor. There were no changes in Ser1177 (serine at codon 1177) or tyrosine phosphorylation of eNOS. These results indicate that VOSO4 induced acute pulmonary vasoconstriction that was mediated in part by the inhibition of endothelial NO production via PKC-dependent phosphorylation of Thr495 of eNOS. Exposure to excessive vanadium may contribute to pulmonary vascular diseases.

WiNGS is a platform for next-generation sequencing data interpretation. It aims to provide a secure environment for researchers and clinicians to collaboratively analyze and interpret sensitive data. One of the key features of WiNGS is its secure federated data storage, which ensures that sensitive data is only accessible to authorized users and is kept confidential. In addition, the platform offers full API functionality, allowing researchers to easily integrate the platform into their own analysis tools or pipelines. Alternatively, it offers a web-based user interface to analyze data, under a range of analysis approaches. These include single sample analysis, trio-based analysis under different inheritance models, and cohort-based analysis. Single sample analysis allows researchers to analyze a single individual's genetic data in order to identify potential genetic variants that may be associated with a particular disease or trait. Trio-based analysis, on the other hand, allows researchers to analyze the genetic data of a child and both of their parents in order to better understand the inheritance patterns of a particular trait or disease. Finally, cohort-based analysis allows researchers to aggregate data from multiple institutions in order to generate anonymous statistical insights. This approach can be particularly useful for large-scale studies involving multiple institutions. Overall, WiNGS is a powerful and flexible platform that provides researchers and clinicians with a secure and federated environment for collaborative next-generation sequencing data interpretation. Its range of analysis approaches, combined with its secure data storage and full API functionality, make it an essential tool for researchers working in the field of genomics.

description: Cutting-edge research in the band engineering of nanowires at the ultimate fine scale is related to the minimum scale of a nanowire-based device. The fundamental issue at the subnanometre scale is whether angle-resolved photoemission spectroscopy (ARPES) can be used to directly measure the momentum-resolved electronic structure of a single wire because of the difficulty associated with assembling single wire into an ordered array for such measurements. Here, we demonstrated that the one-dimensional (1D) confinement of electrons, which are transferred from external dopants, within a single subnanometre-scale wire (subnanowire) could be directly measured using ARPES. Convincing evidence of 1D electron confinement was obtained using two different gold subnanowires with characteristic single metallic bands that were alternately and spontaneously ordered on a stepped silicon template, Si(553). Noble metal atoms were adsorbed at room temperature onto the gold subnanowires while maintaining the overall structure of the wires. Only one type of gold subnanowires could be controlled using external noble metal dopants without transforming the metallic band of the other type of gold subnanowires. This result was confirmed by scanning tunnelling microscopy experiments and first-principles calculations. The selective control clearly showed that externally doped electrons could be confined within a single gold subnanowire. This experimental evidence was used to further investigate the effects of the disorder induced by external dopants on a single subnanowire using ARPES.

description: Preterm delivery can lead to serious infant health outcomes, including death and lifelong disability. Small increases in preterm delivery risk in relation to spatial gradients of air pollution have been reported, but previous studies may have controlled inadequately for individual factors. Using a time-series analysis, which eliminates potential confounding by individual risk factors that do not change over short periods of time, we investigated the effect of ambient outdoor particulate matter with diameter ≤10 μm (PM10) and sulfur dioxide on risk for preterm delivery. Daily counts of preterm births were obtained from birth records in four Pennsylvania counties from 1997 through 2001. We observed increased risk for preterm delivery with exposure to average PM10 and SO2 in the 6 weeks before birth [respectively, relative risk (RR) = 1.07; 95% confidence interval (CI), 0.98–1.18 per 50 μg/m3 increase; RR = 1.15; 95% CI, 1.00–1. 32 per 15 ppb increase], adjusting for long-term preterm delivery trends, co-pollutants, and offsetting by the number of gestations at risk. We also examined lags up to 7 days before the birth and found an acute effect of exposure to PM10 2 days and 5 days before birth (respectively, RR = 1.10; 95% CI, 1.00–1.21; RR = 1.07; 95% CI, 0.98–1.18) and SO2 3 days before birth (RR = 1.07; 95% CI, 0.99–1.15), adjusting for covariates, including temperature, dew point temperature, and day of the week. The results from this time-series analysis, which provides evidence of an increase in preterm birth risk with exposure to PM10 and SO2, are consistent with prior investigations of spatial contrasts.

A critical examination of the statistical symmetries admitted by the Lundgren-Monin-Novikov hierarchy of unconfined turbulence

description: We present a critical examination of the recent article by Waclawczyk et al. (2014) which proposes two new statistical symmetries in the classical theory for turbulent hydrodynamic flows. We first show that both symmetries are unphysical in that they induce inconsistencies due to violating the principle of causality. In addition, they must get broken in order to be consistent with all physical constraints naturally arising in the statistical Lundgren-Monin-Novikov (LMN) description of turbulence. As a result, we state that besides the well-known classical symmetries of the LMN equations no new statistical symmetries exist. Yet, aside from this particular issue, the article by Waclawczyk et al. (2014) is flawed in more than one respect, ranging from an incomplete proof, to a self-contradicting statement up to an incorrect claim. All these aspects will be listed, discussed and corrected, thus obtaining a completely opposite conclusion in our study than the article by Waclawczyk et al. (2014) is proposing.
