INFLUENCE of WATER during MANUFACTURING of APA6 in the THERMOPLASTIC RTM PROCESS

The thermoplastic resin transfer molding (T-RTM) process has the potential for high-volume production of high performance fiber-reinforced components in the automotive industry. The fast anionic polymerization of APA6 and the development of robust injection equipment lead to short cycle times. The sensitivity against water of the reactive APA6 is well known. All resin components from the manufacturer are dried to achieve water content below 200 ppm. In T-RTM high-performance composite manufacturing fibers, binder systems or core materials are needed. During the manufacturing (preforming, handling, infiltration) of these materials it is necessary to ensure that the total amount of water is small enough to achieve good polymerization. Previous studies established the influence of water for nonactivated polymerization. However, there is no knowledge about the influence of water during T-RTM manufacturing using fast-reacting activated polymerization. In this paper, different concentrations of catalyst are investigated to analyze the influence of water in the T-RTM process during curing of the resin. Residual monomer content and viscosity number was measured to analyze the conversion of manufactured plates. To characterize the impact on the mechanical properties, tensile tests were performed. The results show the possibility to monitor the anionic polymerization during the manufacturing by observing the trend of the cavity pressures. In addition, the influence of water on the conversion and the resulting mechanical properties can be compensated by the concentration of the catalyst.

18 The behavior of tropical extreme precipitation under changes in sea surface temperatures (SSTs) 19 is investigated with the Weather Research and Forecasting Model (WRF) in three sets of 20 idealized simulations: small-domain tropical radiative-convective equilibrium (RCE), quasi21 global “aquapatch”, and RCE with prescribed mean ascent from the tropical band in the 22 aquapatch. We find that, across the variations introduced including SST, large-scale circulation, 23 domain size, horizontal resolution and convective parameterization, the change in the degree of 24 convective organization emerges as a robust mechanism affecting extreme precipitation. Higher 25 ratios of change in extreme precipitation to change in mean surface water vapor are associated 26 with increases in the degree of organization, while lower ratios correspond to decreases in the 27 degree of organization. The spread of such changes is much larger in RCE than aquapatch tropics, 28 suggesting that small RCE domains may be unreliable for assessing the temperature-dependence 29 of extreme precipitation or convective organization. When the degree of organization doesn’t 30 change, simulated extreme precipitation scales with surface water vapor. This slightly exceeds 31 Clausius-Clapeyron (CC) scaling, because the near-surface air warms 10-25% faster than the 32 SST in all experiments. Also for simulations analyzed here with convective parameterizations, 33 there is an increasing trend of organization with SST. 34
EPIDEMIOLOGY Ethnic Drinking Cultures and Alcohol Use among Asian American Adults: Findings from a National Survey

Aims: To investigate the influence of ethnic drinking cultures on alcohol use by Asian Americans and how this influ- ence may be moderated by their level of integration into Asian ethnic cultures. Methods: A nationally representative sample of 952 Asian American adults extracted from the Wave 2 National Epidemiologic Survey of Alcohol and Related Conditions data was used. Multiple logistic and linear regression models were fitted, some of which were stratified by nativity. Results: Controlling for finan- cial stress, discrimination and demographic variables, a hypothesized, positive relationship between ethnic drinking cultures and alcohol outcomes held for most drinking outcomes. A hypothesis on the moderating effect of integration into ethnic cultures indi- cated by ethnic language use was supported for US-born Asian Americans. Conclusion: Ethnic drinking cultures may significantly influence alcohol use by Asian Americans. The influence of ethnic drinking cultures may be conditioned by the degree of integration into the ethnic cultures. To inform alcohol interventions for reducing harmful and hazardous alcohol use among immigrants, future research needs to explore the cultural and social processes occurring in immigrant communities that might significantly influence drinking.
Linear Lower Bounds and Conditioning of Differentiable Games

Recent successes of game-theoretic formulations in ML have caused a resurgence of research interest in differentiable games. Overwhelmingly, that research focuses on methods and upper bounds on their speed of convergence. In this work, we approach the question of fundamental iteration complexity by providing lower bounds to complement the linear (i.e. geometric) upper bounds observed in the literature on a wide class of problems. We cast saddle-point and min-max problems as 2-player games. We leverage tools from single-objective convex optimisation to propose new linear lower bounds for convex-concave games. Notably, we give a linear lower bound for $n$-player differentiable games, by using the spectral properties of the update operator. We then propose a new definition of the condition number arising from our lower bound analysis. Unlike past definitions, our condition number captures the fact that linear rates are possible in games, even in the absence of strong convexity or strong concavity in the variables.
Schedule Instability and Unpredictability and Worker and Family Health and Wellbeing

The American labor market is increasingly unequal, characterized by extraordinary returns to work at the top of the market but rising precarity and instability at the bottom of the market. In addition to low wages, short tenure, few benefits, and non­standard hours, many jobs in the retail and food service industries are characterized by a great deal of instability and unpredictability in work schedules. Such workplace practices may have detrimental effects on workers. However, the lack of existing suitable data has precluded empirical investigation of how such scheduling practices affect the health and wellbeing of workers and their families. We describe an innovative approach to survey data collection from targeted samples of service­ sector workers that allows us to collect previously unavailable data on scheduling practices and on health and wellbeing. We then use these data to show that exposure to unstable and unpredictable schedules is negatively associated with household financial security, worker health, and parenting practices.
Hydraulic Reconstruction of the 1818 Giétro Glacial Lake Outburst Flood

In the spring of 1818, ice avalanches from the Giétro Glacier created an ice dam, which in turn formed a glacial lake in the Drance Valley (Canton of Valais, Switzerland). Today, its maximum volume is estimated to have been 25×106 m3. Cantonal authorities commissioned an engineer named Ignaz Venetz to mitigate the risk of the ice dam's failure. He supervised the construction of a tunnel through which a large volume of water was drained as the lake rose (9×106 m3 according to his estimates and 11×106 m3 according to our model). After 2.5 days of slow drainage, the ice dam failed on 16 June 1818 and caused major flooding in the Drance Valley up to 40 km downstream, resulting in about 40 deaths. Venetz's lake monitoring notes, numerous testimonies gathered in the disaster's aftermath, and our field survey have made it possible to collect a wealth of information on this event, which is one of the world's major documented glacial lake outburst floods. Reconstructing major outburst floods remains challenging because not only do they involve enormous volumes of water spreading over long distances but they are also associated with additional physical processes such as massive erosion; intense transport of ice, sediment, and debris; and damage to vegetation and buildings. This paper attempts to reconstruct the 1818 Giétro flood by focusing on its water component. We develop a simple model to estimate the initial hydrograph during the slow drainage and failure phases. The flood's features are deduced by solving the shallow‐water equations numerically. The computational framework involves six free parameters, of which five are constrained by physical considerations. Using iterative manual parameter adjustments, we matched the numerical simulations to the historical data. We found that the peak discharge was close to 14,500 m3/s, the flood's front velocity was about 6 m/s, and flow depth varied considerably along the River Drance's bed (from 30 m just downstream of the ice dam to 2 m on the alluvial fan, 24 km west of the dam). To achieve a good agreement between computations and historical data, we had to select a high value for the Manning friction coefficient n (with n as large as 0.08 s/m1/3). As the Drance Valley is narrow, high flow resistance caused the flood's leading edge to behave like a plug, moving at a fairly constant velocity, with little dependence on what happened behind it. This result may explain why a simple flood routing model is able to reproduce the flood's features, because in an Alpine valley, a lateral spreading of the water volume is limited.
ENIGMA BRCA1/2 Gene Variant Classification Criteria ENIGMA (Evidence-based Network for the Interpretation of Germline Mutant Alleles) is an international consortium of investigators focused on determining the clinical significance of sequence variants in breast cancer genes. Information about the co

Rules for Variant Classification: Rules describing the 5 class system for classification of BRCA1/2 gene variants were initially devised and documented by ENIGMA Steering committee members, and revised with input from ENIGMA collaborators. These ENIGMA criteria provide a baseline for standardized clinical classification of BRCA1/2 gene sequence variation that may be linked to patient and family management in the genetic counseling arena according to published guidelines (Plon et al., 2008). At the present time, the proposed classification criteria are intended to differentiate germline high risk variants (associated with cancer risk equivalent to classical pathogenic variants that are known or predicted encode a premature termination codon i.e. nonsense or frameshift) from variants with low or no risk. These guidelines are not intended for the evaluation and classification of variants associated with an intermediate or moderate level of risk e.g. BRCA1 c.5096G>A p.Arg1699Gln (Spurdle et al., 2012). It should also be noted that, based on observations in mouse model and ex-vivo analyses (Drost et al., 2011, Meeks et al., 2016, Drost et al., 2016), it is currently unclear what the correlation is between germline variant classification for cancer risk and germline/somatic variant classification for response to therapy eg with PARP inhibitors.
THE FIRST EXPERIMENT OF A HIGH-ACCURACY 2D COLOR MARKER IN SPACE

This paper discusses a new planar twodimensional (2D) color marker for space applications. Specialized visual markers are commonly employed to measure position and attitude using image processing technology. In previous missions, a three-dimensional (3D) visual marker utilizing a rod was used for rendezvous and docking with the International Space Station (ISS) or for capturing a module with a robotic arm on the ISS. The 3D marker is equipped with a protruding rod on a flat plane. A central purpose of the protruding rod is highprecision measurement of relative attitude by triangulation. Due to the shape of the protruding rod, mounting positions for the 3D visual marker are limited to avoid collision with astronauts and space robots. In addition, depending on the camera angle, flat plane’s feature points may be obscured by the protruding rod. In this case, accurate measurement of position and attitude is unobtainable. In this study, the objective is to develop a new 2D visual marker for space applications that solves the above mentioned technical issues. In addition, colorization of the 2D visual marker is envisioned to improve marker detectability in the space environment. An onorbit experiment was conducted using a 2D color marker to verify its performance. The following is a discussion on the results of this experiment.
Genotyping of Malassezia pachydermatis disclosed genetic variation in isolates from dogs in Colombia

ABSTRACT: Malassezia pachydermatis is a lipophilic and lipid-dependent yeast mostly isolated from animals’ skin; hence, it is regarded as a zoophilic species causing otitis externa in dogs. Aspects associated with its epidemiology and pathogenicity is a matter of interest. This study aimed to conduct a molecular characterization of 43 isolates of M. pachydermatis obtained from dogs with otitis externa. For this purpose, the 5.8S internal transcribed spacer 2 (ITS2) and D1/D2 26S rRNA regions were amplified, sequenced and analyzed using restriction fragment length polymorphism (RFLP) with AluI, CfoI, and BstF5I endonucleases. Phylogenetic analyses revealed that these isolates grouped with the sequence types I, IV and V, previously proposed for M. pachydermatis. Interestingly, we found a new polymorphic RFLP pattern using BstF5I, these isolates were associated with the sequence types IV and V, nevertheless an association between polymorphic RFLP patterns, and fosfolipase activity or canine population data was not observed. These findings underline the genetic diversity of M. pachydermatis and provide new insights about the epidemiology of this species in the analyzed population.

SCATTERING OF A SPHERICAL WAVE BY A THIN HARD STRIP

This paper is concerned with a theoretical solution to the problem of scattering of a spherical wave by a strip. The strip is infinitely thin, infinite in length and of width 2a. The problem is first brought into the wave space through a spatial Fourier transform of the wave equation and of the boundary conditions on the strip. The Fourier transform is taken with respect to the co-ordinate axis parallel to the edges of the strip. Using the boundary conditions on the strip leads to an integral equation of the first kind, the unknown of which is the discontinuous potential jump across the strip. This latter is expanded into some suitable functions and the coefficients of the series expansion are thereafter determined from an infinite system of equations. The system’s matrix is found to be mainly diagonal and tests on the stability of the numerical calculations suggest the significant number of equations in the system be limited to approximately ka+5, with k being the wavenumber. Finally, after solving the system of equations and going back to the scattered field, the expression of this latter is made from an infinite series over some infinite double integrals whose approximate evaluation is made with the help of the two-dimensional stationary phase method. This treatment corresponds to the far field case. A further consideration of the right side of the system of equations leads to an improved value of the scattered field. Comparisons are made to an approximated prediction of the scattered field by using the Biot and Tolstoy exact theory of diffraction of a spherical wave by a hard wedge. The implementation of this approach to the strip requires the further consideration of the multiple diffraction between its edges for improving the calculated value of the scattered field. Some numerical examples are treated with discussions on their results. 7 1999 Academic Press
Evaluation of Subclinical Hypothyroidism on Auditory Divided Attention

Introduction: Subclinical hypothyroidism is an endocrine disorder that can adversely affect cognitive performance. In this regard, patients with subclinical hypothyroidism may develop poor attention. However, the effects of this endocrine disorder on auditory attention is unclear. This study aims to evaluate the impact of subclinical hypothyroidism on auditory divided attention. Materials and Methods: This cross-sectional, case control study was performed on 30 adult patients, aged 20-40 years, who met the study inclusion criteria. Based on their Thyroid Stimulating Hormone (TSH) level, the subjects were divided into two case groups (each with 15 patients) with a TSH level of 5˂TSH≤10 and 10˂TSH≤15. A healthy control group was recruited with matched age, sex, and education with the case groups. The participants were evaluated by the Persian version of the Bergen dichotic listening test. Among different experimental situations that included non-forced attention, forced right, and forced left, we chose the non-forced attention. Statistical analysis was done in SPSS V. 25. Results: There was a significant difference between the subclinical hypothyroid (5˂TSH≤10 group) and controls in the scores of the right and left ear. However, there was no significant difference between scores of right and left ear in subclinical hypothyroid (10˂TSH≤15 group). No significant difference in scores of the right and left ear was found between men and women in three groups. Conclusion: Subclinical hypothyroidism had no effect on auditory divided attention.
A Novel Method to Optimize Autologous Adipose Tissue Recovery with Extracellular Matrix Preservation

This work aims to characterize a new method to recover low-manipulated human adipose tissue, enriched with adipose tissue-derived mesenchymal stem cells (ATD-MSCs) for autologous use in regenerative medicine applications. Lipoaspirated fat collected from patients was processed through Lipocell, a Class II-a medical device for dialysis of adipose tissue, by varying filter sizes and washing solutions. ATD-MSC yield was measured with flow cytometry after stromal vascular fraction (SVF) isolation in fresh and cultured samples. Purification from oil and blood was measured after centrifugation with spectrophotometer analysis. Extracellular matrix preservation was assessed through hematoxylin and eosin (H&E) staining and biochemical assay for total collagen, type-2 collagen, and glycosaminoglycans (GAGs) quantification. Flow cytometry showed a two-fold increase of ATD-MSC yield in treated samples in comparison with untreated lipoaspirate; no differences where reported when varying filter size. The association of dialysis and washing thoroughly removed blood and oil from samples. Tissue architecture and extracellular matrix integrity were unaltered after Lipocell processing. Dialysis procedure associated with Ringer’s lactate preserves the proliferation ability of ATD-MSCs in cell culture. The characterization of the product showed that Lipocell is an efficient method for purifying the tissue from undesired byproducts and preserving ATD-MSC vitality and extracellular matrix (ECM) integrity, resulting in a promising tool for regenerative medicine applications.
Comparing Low Power Listening Techniques with Wake-up Receiver Technology

One of the major challenges in wireless sensor networks is in reducing power consumption of the individual motes while not degrading the functionality of the network as a whole. With wireless sensor technology becoming more wide spread and larger deployments of this technology being rolled out post deployment issues such as battery replacements become a bigger issue. Reducing power consumption is essential in situations where it is infeasible or impractical to frequently replace batteries. Reducing the power consumption of the motes to a level where batteries can last years or where ideally to levels where energy scavenging becomes more feasible, resulting in battery-less operation of wireless networks, is a major research challenge. One of the main energy consumers on a wireless mote is the radio transceiver. Current approaches using low power listening techniques to reduce mote power while maintaining meshing capabilities and this paper compares the state of the art in low power listening (BOX-MAC 1 and 2) with the latest in commercially available wake up radio technology (Austria Microsystems (AMS) AS3933) to determine which approach is more efficient from an energy consumption view. A theoretical approach has been taken to compare achievable lifetimes of motes under different traffic situations using both Low Power Listening (LPL) methods and Wake up Receivers (WUR). This is then compared against empirical data. As this paper shows, when considering power draw of radios in different configurations, WURs consume up to 20 times less power compared to techniques, thereby enabling indoor energy harvesting (EH) solutions to become practical.
