Creators: name: Fryer, Ronald
Publisher: name: London South Bank University
Year: 1980

description: The work described is the result of research Carried out on some aspects of the biology of the ,Macroinvertebrates (principally crustaceans, insects and water mites) which have caused infestation problems in a water distribution system. A survey of the literature was carried out to determine the occurrence of macroinvertebrates in the water mains and the treatment methods used by other authorities with similar problems. The laboratory culture of the organisms, and the determination of the larval instars of Paratanytarsus sp. nov. (Diptera: Chironomidae) is described. Surveys of the macroinvertebrates at the treatment works and in the water distribution system were carried out over one and two year periods respectively, to determine the efficiency of the treatment, the extent of the infestations and the annual variations within the populations. Experiments were carried out to determine the effects of flow, food, chlorine and two pesticides, pyrethrins and Abate, on selected members of the mains fauna. Experiments were also carried out using a model rapid sand filter to determine the extent of penetration of the micro-organisms used as food. A discussion of the results and reasons for the success of certain organisms is given.

description: Socioeconomic determinants of risky sexual behaviors in sub‐Saharan Africa are well known. The socioeconomic determinants of the sexual behaviors of university students, however, remain unclear. This case control study aimed to investigate the socioeconomic determinants of risky sexual behavior and HIV seropositivity among university students in KwaZulu‐Natal (KZN), South Africa. Participants (N = 500; 375 HIV uninfected and 125 HIV infected) from four public higher educational institutions in KZN were recruited, using a non‐randomized strategy. Socioeconomic status was assessed by food insecurity, access to the government loan scheme, and sharing of the bursary/loan with family. The findings of this study suggest that students reporting food insecurity were 1.87 times more likely to have multiple sexual partners; 3.18 times more likely to engage in transactional sex for money; and presented a fivefold higher risk of engaging in transactional sex for basic needs other than money. Accessing the government financing for education and sharing of the bursary/loan with family was also significantly associated with an increased risk of having an HIV seropositive status. A significant association between socioeconomic measures, risky sexual behavior, and HIV seropositivity is demonstrated in this study. Moreover, the socioeconomic risks and drivers when determining and/or developing HIV prevention interventions, including preexposure prophylaxis use, should be considered by healthcare providers based at campus health clinics.

description: Prenatal exposure to organophosphate pesticides (OPs) has been associated with adverse neurodevelopmental outcomes in childhood, including low IQ, Pervasive Developmental Disorder (PDD), attention problems and ADHD. Many of these disorders involve impairments in social functioning. Thus, we investigated the relationship between biomarkers of prenatal OP exposure and impaired reciprocal social behavior in childhood, as measured by the Social Responsiveness Scale (SRS). Using a multi-ethnic urban prospective cohort of mother-infant pairs in New York City recruited between 1998 and 2002 (n=404) we examined the relation between third trimester maternal urinary levels of dialkylphosphate (ΣDAP) OP metabolites and SRS scores among 136 children who returned for the 7–9 year visit. Overall, there was no association between OPs and SRS scores, although in multivariate adjusted models, associations were heterogeneous by race and by sex. Among blacks, each 10-fold increase in total diethylphosphates (ΣDEP) was associated with poorer social responsiveness (β = 5.1 points, 95% confidence interval (CI) 0.8, 9.4). There was no association amongst whites or Hispanics, or for total ΣDAP or total dimethylphosphate (ΣDMP) biomarker levels. Additionally, stratum-specific models supported a stronger negative association among boys for ΣDEPs (β = 3.5 points, 95% CI 0.2, 6.8), with no notable association among girls. Our results support an association of prenatal OP exposure with deficits in social functioning among blacks and among boys, although this may be in part reflective of differences in exposure patterns.

description: The spectrum of a bound state of three identical particles with a mass $m$ in a finite cubic box is studied. It is shown that in the unitary limit, the energy shift of a shallow bound state is given by $ΔE=c (κ^2/m)\,(κL)^{-3/2}|A|^2\exp(-2κL/\sqrt{3})$, where $κ$ is the bound-state momentum, $L$ is the box size, $|A|^2$ denotes the three-body analog of the asymptotic normalization coefficient of the bound state wave function and $c$ is a numerical constant. The formula is valid for $κL\gg 1$.
description: An error in the calculation of the overlap integral in Eq. (11) is corrected. Our main result given in Eq. (26) remains the same, except the numerical value of the constant c, which changes approximately by 10%

description: When we compare the influences of two causes on an outcome, if the conclusion from every group is against that from the conflation, we think there is Simpson's Paradox. The Existing Causal Inference Theory (ECIT) can make the overall conclusion consistent with the grouping conclusion by removing the confounder's influence to eliminate the paradox. The ECIT uses relative risk difference Pd = max(0, (R - 1)/R) (R denotes the risk ratio) as the probability of causation. In contrast, Philosopher Fitelson uses confirmation measure D (posterior probability minus prior probability) to measure the strength of causation. Fitelson concludes that from the perspective of Bayesian confirmation, we should directly accept the overall conclusion without considering the paradox. The author proposed a Bayesian confirmation measure b* similar to Pd before. To overcome the contradiction between the ECIT and Bayesian confirmation, the author uses the semantic information method with the minimum cross-entropy criterion to deduce causal confirmation measure Cc = (R -1)/max(R, 1). Cc is like Pd but has normalizing property (between -1 and 1) and cause symmetry. It especially fits cases where a cause restrains an outcome, such as the COVID-19 vaccine controlling the infection. Some examples (about kidney stone treatments and COVID-19) reveal that Pd and Cc are more reasonable than D; Cc is more useful than Pd.

description: Dense soft glasses show strong collective caging behavior at sufficiently low temperatures. Using molecular dynamics simulations of a model glass former, we show that the incorporation of activity or self-propulsion, f0, can induce cage breaking and fluidization, resulting in a disappearance of the glassy phase beyond a critical f0 . The diffusion coefficient crosses over from being strongly to weakly temperature dependent as f0 is increased. In addition, we demonstrate that activity induces a crossover from a fragile to a strong glass and a tendency for clustering of active particles. Our results are of direct relevance to the collective dynamics of dense active colloidal glasses and to recent experiments on tagged particle diffusion in living cells.

Tax Policies and the Labor Market

description: In the first chapter, I study the Work Opportunity Tax Credit (WOTC) which is a federal tax credit available to businesses who hire employees from certain targeted groups that have consistently faced significant barriers to employment. The PATH Act added long-term unemployment recipients as a target group for the WOTC in 2015. Using CPS data and both a difference-in-differences and triple difference model, I assess the effect of the inclusion of this group in the WOTC on employment and wages for newly eligible individuals. The WOTC increased the monthly probability a long-term unemployment recipient started a job by 2.3 percentage points in the post period from a base monthly reemployment rate of 15.8%. I find no evidence of the tax credit being passed through to workers in the form of higher wages or benefits, and I find no evidence of increased employee churn due to the employer subsidy's minimum hours requirement. Finally, I find that the employment increase is largely driven by workers with thirty or more weeks of unemployment instead of those just above the six month eligibility cutoff. The second chapter examines Tax Increment Financing (TIF) districts, the largest economic development program in the City of Chicago, allocating nearly $1 billion in tax revenues annually. Using comprehensive data on employment by place of work and place of residency, this chapter studies if TIF districts see an increase in jobs as a result of designation, and whether the residents in neighborhoods designated as TIF districts see employment benefits from the designation. To account for the endogenous selection of TIF areas, I implement a propensity score matching dynamic difference-in-differences approach exploiting differential timing of TIF designation. I find that TIF designation increases the number of jobs in a selected census block by 15% over 5 years. However, the employment levels of residents living in or around TIF districts shows no increase due to designation. I also find evidence of substantial spillover effects to adjacent blocks, and limited neighborhood compositional changes. These findings suggest that TIF districts can be effective in revitalizing commercial and industrial areas while the ability of TIF to improve outcomes in blighted residential neighborhoods surrounding the district is limited. In the final chapter, I use comprehensive Census Bureau data on interstate migration to explore how tax rate changes impact the destination choice of interstate movers using a simulated tax rate instrumental variables approach to control for endogenous wage changes within an industry. I find that a 1% change in disposable income changes the relative proportions of interstate movers by about 0.1%, a very modest elasticity. I do find evidence of higher elasticities for higher income workers.

description: Organophosphate flame retardants (OPFRs) are commonly added to consumer products to reduce their flammability. Based on levels of OPFRs in indoor environments, human exposure is likely chronic and ubiquitous. Animal studies suggest that exposure to some OPFRs may result in adverse health impacts, particularly for tris (1,3-dichloropropyl) phosphate (TDCPP); however, human data on the impacts of exposure to OPFRs are lacking. To design human studies, more information is needed on the stability of measured OPFRs in human samples over time. In this study, we sought to assess the degree of temporal variability of urinary TDCPP and triphenyl phosphate (TPP) metabolites throughout pregnancy in a cohort of women from central North Carolina.

description: Multi-wavelength observations of the black-widow binary system 2FGL J2339.6-0532 are reported. The Fermi gamma-ray source 2FGL J2339.6-0532 was recently categorized as a black widow in which a recycled millisecond pulsar (MSP) is evaporating up the companion star with its powerful pulsar wind. Our optical observations show clear sinusoidal light curves due to the asymmetric temperature distribution of the companion star. Assuming a simple geometry, we constrained the range of the inclination angle of the binary system to 52$^{\circ}$ < i < 59$^{\circ}$, which enables us to discuss the interaction between the pulsar wind and the companion in detail. The X-ray spectrum consists of two components: a soft, steady component that seems to originate from the surface of the MSP, and a hard variable component from the wind-termination shock near the companion star. The measured X-ray luminosity is comparable to the bolometric luminosity of the companion, meaning that the heating efficiency is less than 0.5. In the companion orbit, 10$^{11}$ cm from the pulsar, the pulsar wind is already in particle dominant-stage, with a magnetization parameter of $σ$ < 0.1. In addition, we precisely investigated the time variations of the X-ray periodograms and detected a weakening of orbital modulation. The observed phenomenon may be related to an unstable pulsar-wind activity or a weak mass accretion, both of which can result in the temporal extinction of radio-pulse.

description: Topological phases can not only be protected by internal symmetries (e.g., time-reversal symmetry), but also by crystalline symmetries, such as reflection or rotation symmetry. Recently a complete topological classification of reflection symmetric insulators, superconductors, nodal semimetals, and nodal superconductors has been established. In this article, after a brief review of the classification of reflection-symmetry-protected semimetals and nodal superconductors, we discuss an example of a three-dimensional topological Dirac semimetal, which exhibits time-reversal symmetry as well as reflection and rotation symmetries. We compute the surface state spectrum of this Dirac semimetal and identify the crystal lattice symmetries that lead to the protection of the surface states. We discuss the implications of our findings for the stability of the Fermi arc surface states of the Dirac material Na$_3$Bi. Our analysis suggests that the Fermi arc of Na$_3$Bi is gapped except at time-reversal invariant surface momenta, which is in agreement with recent photoemission measurements.

In vitro screening for population variability in toxicity of pesticide-containing mixtures

description: Population-based human in vitro models offer exceptional opportunities for evaluating the potential hazard and mode of action of chemicals, as well as variability in responses to toxic insults among individuals. This study was designed to test the hypothesis that comparative population genomics with efficient in vitro experimental design can be used for evaluation of the potential for hazard, mode of action, and the extent of population variability in responses to chemical mixtures. We selected 146 lymphoblast cell lines from 4 ancestrally and geographically diverse human populations based on the availability of genome sequence and basal RNA-seq data. Cells were exposed to two pesticide mixtures – an environmental surface water sample comprised primarily of organochlorine pesticides and a laboratory-prepared mixture of 36 currently used pesticides – in concentration response and evaluated for cytotoxicity. On average, the two mixtures exhibited a similar range of in vitro cytotoxicity and showed considerable inter-individual variability across screened cell lines. However, when in vitroto-in vivo extrapolation (IVIVE) coupled with reverse dosimetry was employed to convert the in vitro cytotoxic concentrations to oral equivalent doses and compared to the upper bound of predicted human exposure, we found that a nominally more cytotoxic chlorinated pesticide mixture is expected to have greater margin of safety (more than 5 orders of magnitude) as compared to the current use pesticide mixture (less than 2 orders of magnitude) due primarily to differences in exposure predictions. Multivariate genome-wide association mapping revealed an association between the toxicity of current use pesticide mixture and a polymorphism in rs1947825 in C17orf54. We conclude that a combination of in vitro human population-based cytotoxicity screening followed by dosimetric adjustment and comparative population genomics analyses enables quantitative evaluation of human health hazard from complex environmental mixtures. Additionally, such an approach yields testable hypotheses regarding potential toxicity mechanisms.

description: Phthalate esters are man-made chemicals commonly used as plasticizers and solvents, and humans may be exposed through ingestion, inhalation, and dermal absorption. Little is known about predictors of phthalate exposure, particularly in Asian countries. Because phthalates are rapidly metabolized and excreted from the body following exposure, it is important to evaluate whether phthalate metabolites measured at a single point in time can reliably rank exposures to phthalates over a period of time. We examined the concentrations and predictors of phthalate metabolite concentrations among 50 middle-aged women and 50 men from two Shanghai cohorts, enrolled in 1997-2000 and 2002-2006, respectively. We assessed the reproducibility of urinary concentrations of phthalate metabolites in three spot samples per participant taken several years apart (mean interval between first and third sample was 7.5 years [women] or 2.9 years [men]), using Spearman's rank correlation coefficients and intra-class correlation coefficients. We detected ten phthalate metabolites in at least 50% of individuals for two or more samples. Participant sex, age, menopausal status, education, income, body mass index, consumption of bottled water, recent intake of medication, and time of day of collection of the urine sample were associated with concentrations of certain phthalate metabolites. The reproducibility of an individual's urinary concentration of phthalate metabolites across several years was low, with all intra-class correlation coefficients and most Spearman rank correlation coefficients ≤ 0.3. Only mono(2-ethylhexyl) phthalate, a metabolite of di(2-ethylhexyl)phthalate, had a Spearman rank correlation coefficient ≥ 0.4 among men, suggesting moderate reproducibility. These findings suggest that a single spot urine sample is not sufficient to rank exposures to phthalates over several years in an adult urban Chinese population.

description: The color X-ray camera SLcam(R) is a full-field, single photon detector providing scanning free, energy and spatially resolved X-ray imaging. Spatial resolution is achieved with the use of polycapillary optics guiding X-ray photons from small regions on a sample to distinct energy dispersive pixels on a CCD. Applying sub-pixel resolution, signals from individual capillary channels can be distinguished. Accordingly the SLcam(R) spatial resolution can be released from pixel size being confined rather to a diameter of individual polycapillary channels. In this work a new approach to sub-pixel resolution algorithm comprising photon events also from the pixel centers is proposed. The details of the employed numerical method and several sub-pixel resolution examples are presented and discussed.

Top Quark Asymmetry in boosted single-lepton events at 13 TeV proton-proton collisions

Publisher: name: University of Illinois at Chicago
Year: 2022
Subjects: Uncategorized

description: The top quark plays a special role in many Beyond the Standard Model theories that predict new massive particles decaying into a top quark and a top anti-quark pair (tt). Depending on the momentum of massive particles (hundreds of GeV or a few TeV), the decay products may be distributed isotropically or highly collimated. This thesis presents the measurement of the charge asymmetry for highly boosted tt pairs decaying in the single lepton + jets topology. The analysis is performed using 138 fb-1 of data collected in pp collisions at s = 13 TeV with the CMS detector during Run 2 of the Large Hadron Collider. The event selection is optimized for tt pairs produced with large Lorentz- boosts resulting in non-isolated leptons and overlapping jets from the t -> bW -> bqq decay. The top quark charge asymmetry is measured for events with t ̄t invariant mass larger than 750 GeV and corrected for detector and acceptance effects using a binned maximum likelihood fit. The measured value of Ac_full = 0.0069 ± 0.0044(stat)+0.0065(syst) ± 0.0032(MCstat) is 0.0069 in good agreement with the standard model prediction at NNLO in perturbation theory with NLO electroweak corrections. Differential distributions for two invariant mass bins are also presented.

description: An analytical model is derived for the probability of failure (P-fail) to spatially acquire an optical link with a jittering search beam. The analytical model accounts for an arbitrary jitter spectrum and considers the associated correlations between jitter excursions on adjacent tracks of the search spiral. An expression of P-fail in terms of basic transcendental functions is found by linearizing the exact analytical model with respect to the correlation strength. Predictions from the models indicate a strong decrease of P-fail with increasing correlation-strength, which is found to be in excellent agreement to results from Monte Carlo simulations. The dependency of P-fail on track-width and scan speed is investigated, confirming previous assumptions on the impact of correlations. Expressions and applicable constraints are derived for the limits of full and no correlations, and the optimal track width to minimize the acquisition time is computed for a range of scan speeds. The model is applicable to optical terminals equipped with a fast beam steering mirror, as often found for optical communication missions in space.

description: We estimate the stellar masses of disk galaxies with two independent methods: a photometrically self-consistent color$-$mass-to-light ratio relation (CMLR) from population synthesis models, and the Baryonic Tully-Fisher relation (BTFR) calibrated by gas rich galaxies. These two methods give consistent results. The CMLR correctly converts distinct Tully-Fisher relations in different bands into the same BTFR. The BTFR is consistent with $M_b \propto V_f^4$ over nearly six decades in mass, with no hint of a change in slope over that range. The intrinsic scatter in the BTFR is negligible, implying that the IMF of disk galaxies is effectively universal. The gas rich BTFR suggests an absolute calibration of the stellar mass scale that yields nearly constant mass-to-light ratios in the near-infrared (NIR): $0.57\;M_{\odot}/L_{\odot}$ in $K_s$ and $0.45\;M_{\odot}/L_{\odot}$ at $3.6μ$. There is only modest intrinsic scatter ($\sim 0.12$ dex) about these typical values. There is no discernible variation with color or other properties: the NIR luminosity is a good tracer of stellar mass.

description: Pesticides have been associated with Parkinson’s disease (PD), and protective gloves and workplace hygiene can reduce pesticide exposure. We assessed whether use of gloves and workplace hygiene modified associations between pesticides and PD. The Farming and Movement Evaluation (FAME) Study is a nested case-control study within the Agricultural Health Study. Use of protective gloves, other PPE, and hygiene practices were determined by questionnaire (69 cases and 237 controls were included). We considered interactions of gloves and hygiene with ever-use of pesticides for all pesticides with ≥ 5 exposed and unexposed cases and controls in each glove-use stratum (paraquat, permethrin, rotenone, and trifluralin). 61% of respondents consistently used protective gloves and 87% consistently used ≥ 2 hygiene practices. Protective glove use modified the associations of paraquat and permethrin with PD: neither pesticide was associated with PD among protective glove users, while both pesticides were associated with PD among non-users (paraquat OR 3.9 [95% CI 1.3, 11.7], interaction p=0.15; permethrin OR 4.3 [95% CI 1.2, 15.6] interaction p=0.05). Rotenone was associated with PD regardless of glove use. Trifluralin was associated with PD among people who used <2 hygiene practices (OR 5.5 [95% CI 1.1, 27.1]) but was not associated with PD among people who used 2 or more practices (interaction p=0.02). Although sample size was limited in the FAME study, protective glove use and hygiene practices appeared to be important modifiers of the association between pesticides and PD and may reduce risk of PD associated with certain pesticides.

description: Taking paid work among men and women beyond pension age as an example, the contribution examines the interrelationship between life courses, gendered welfare regimes, and later-life employment outcomes. Using both quantitative and qualitative data, the article focuses on the role of inequalities, gender and marital status for working despite receiving a pension, and on the subjective reasons for this employment. The quantitative analyses are based on the English Longitudinal Study of Ageing (ELSA) and the German Ageing Survey (DEAS), and the qualitative evidence on semi-structured interviews with working pensioners in Germany and the UK. Gender differences in working can be traced back in part to differences in educational qualification and in pre-retirement class. Although no general gender differences in the reasons for paid employment can be found, financial reasons are mentioned much more often by divorced women in Germany and widowed women in the UK than by men and by married women. The qualitative data underlines the special role earned income plays for divorced women and, more generally, the variety of reasons which motivate pensioners to work for pay. Furthermore, pension age is less meaningful for mothers because of their patchier careers. All in all, (poor) labour market chances and household dynamics in old age are interrelated in gendered patterns of old age employment, and accompanied by specific interpretations of this work.

description: The purpose of this study was to compare oral health related quality of life (OHRQoL) before and after general anesthesia (GA) for complete oral rehabilitation in children. The Early Childhood Oral Health Impact Scale (ECOHIS) survey was administered to legal guardians of healthy pediatric patients seen for complete oral rehabilitation under GA at a university outpatient care center. The survey was administered again at the 6-month recall visit to assess any change in OHRQoL. Baseline and follow up scores were analyzed using paired samples t test. A total of 86 subjects completed baseline surveys. Thirty-three children returned for the 6-month follow-up visit. There was a significant difference in the ECOHIS scores prior to GA (Mean=27.15, SD=8.31) compared to after GA (Mean=18.94, SD=5.36) for complete oral rehabilitation; p<.001. There was a significant difference in the baseline Child Impact Score subdomain (Mean=17.89, SD=5.37) compared to the follow-up score (Mean=12.84, SD=3.54); p<.001. There was a significant difference in the baseline Family Impact Score subdomain (Mean=9.26, SD=3.97) compared to the follow-up score (Mean=6.09, SD=2.61); p<.001. OHRQoL significantly improved for both children and their families following GA for complete oral rehabilitation.

description: Zidovudine-based antiretroviral therapies (ART) for treatment of HIV-infected pregnant women have markedly reduced mother-to-child transmission of the human immunodeficiency virus (HIV-1) from ~25% to <1%. However, zidovudine (ZDV; AZT), a nucleoside analogue, induces chromosomal damage, gene mutations, and cancer in animals following direct or transplacental exposures. To determine if chromosomal damage is induced by ZDV in infants exposed transplacentally, we evaluated micronucleated reticulocyte frequencies (%MN-RET) in 16 HIV-infected ART-treated mother-infant pairs. Thirteen women received prenatal ART containing ZDV; 3 received ART without ZDV. All infants received ZDV for 6 weeks postpartum. Venous blood was obtained from women at delivery, and from infants at 1–3 days, 4–6 weeks, and 4–6 months of life; cord blood was collected immediately after delivery. Ten cord blood samples (controls) were obtained from infants of HIV-uninfected women who did not receive ART. %MN-RET was measured using a single laser 3-color flow cytometric system. Ten-fold increases in %MN-RET were seen in women and infants who received ZDV-containing ART prenatally; no increases were detected in 3 women and infants who received prenatal ART without ZDV. Specifically, mean %MN-RET in cord blood of ZDV-exposed infants was 1.67±0.34 compared with 0.16±0.06 in non-ZDV ART-exposed infants (P=0.006) and 0.12±0.02 in control cord bloods (p<0.0001). %MN-RET in ZDV-exposed newborns decreased over the first 6 months of life to levels comparable to cord blood controls. These results demonstrate that transplacental ZDV exposure is genotoxic in humans. Long-term monitoring of HIV-uninfected ZDV-exposed infants is recommended to ensure their continued health.

description: We present a theory of the Förster energy transfer between the arrays of donor and acceptor molecules lying on the planar metallic mirror. We reveal strong modification of the effective transfer rate by the mirror in the incoherent pumping regime. The rate can be either suppressed or enhanced depending on the relative positions between acceptor and donor arrays. The strong modification of the transfer rate is a collective effect, mediated by the light-induced coupling between the donors; it is absent in the single donor model.

description: Hepatocellular carcinoma, which is one of the most prevalent life-threatening human cancers, is showing an increased incidence worldwide. Recent evidence indicates that the development of hepatocellular carcinoma is associated with not only genetic alterations, but also with profound epigenetic changes. This review summarizes the current knowledge about epigenetic alterations during rodent hepatocarcinogenesis, considers the similarities and differences in epigenetic effects of genotoxic and non-genotoxic rodent liver carcinogens, and discusses the possible role of these effects in the causality of liver tumor development.

description: With the continuous rise in the popularity of Android mobile devices, automated testing of apps has become more important than ever. Android apps are event-driven programs. Unfortunately, generating all possible types of events by interacting with the app's interface is challenging for an automated testing approach. Callback-driven testing eliminates the need for event generation by directly invoking app callbacks. However, existing callback-driven testing techniques assume prior knowledge of Android callbacks, and they rely on a human expert, who is familiar with the Android API, to write stub code that prepares callback arguments before invocation. Since the Android API is huge and keeps evolving, prior techniques could only support a small fraction of callbacks present in the Android framework. In this work, we introduce Columbus, a callback-driven testing technique that employs two strategies to eliminate the need for human involvement: (i) it automatically identifies callbacks by simultaneously analyzing both the Android framework and the app under test, and (ii) it uses a combination of under-constrained symbolic execution (primitive arguments), and type-guided dynamic heap introspection (object arguments) to generate valid and effective inputs. Lastly, Columbus integrates two novel feedback mechanisms -- data dependency and crash-guidance, during testing to increase the likelihood of triggering crashes, and maximizing coverage. In our evaluation, Columbus outperforms state-of-the-art model-driven, checkpoint-based, and callback-driven testing tools both in terms of crashes and coverage.
On the dimensional analysis for the creep rate prediction of ceramic fibers

description: A novel semi-empirical equation for the steady-state creep rate description of ceramic fibers is here proposed. Dimensional analysis was applied to identify the relationship between the variables related to the creep rate. Besides the variables known from the Arrhenius creep equation, a temperature factor that accounts for changes with the temperature was also taken into consideration. The resultant equation shows that the creep rate is proportional to the temperature, applied stress and two material constants, as well as inversely proportional to the fiber grain size. The two material constants k and C described in the equation can be easily determined by creep tests at different temperatures under the same applied stress. Therefore, this equation can be more efficiently applied to predict the creep rate of ceramic fibers under different applied stresses and initial grain sizes. To confirm this, the proposed equation was used to fit the creep rate data set of two ceramic fibers, Nextel 720 and CeraFib 75. In summary, the equation provides a good fit (adjusted R-squared up to 0.97) and prediction for the experimental data of tests with different temperatures, applied stresses and initial grain sizes.

description: Formaldehyde is widely used in the United States and other countries. Occupational and environmental exposures to formaldehyde may be associated with an increased risk of leukemia in exposed individuals. However, risk assessment of formaldehyde and leukemia has been challenging due to inconsistencies in human and animal studies and the lack of a known mechanism for leukemia induction. Here we provide a summary of the symposium at the Environmental Mutagen Society Meeting in 2008, which focused on the epidemiology of formaldehyde and leukemia, potential mechanisms, and implication for risk assessment, with emphasis on future directions in multidisciplinary formaldehyde research.

description: In this study, porous zirconia membranes were developed by aqueous tape casting. The influence of poly (methyl methacrylate) (PMMA) as a pore former, and sintering temperatures (1300, 1400, and 1500 °C) on open porosity and pore size was investigated. The rheological behaviour of the suspensions was measured. The slurries showed pseudoplastic behavior, which is desirable for tape casting. Functionalization with an amino silane precursor (3- aminopropyl triethoxysilane, APTES) was carried out to increase the hydrophilic properties of the membranes. The functionalized samples were characterized by SEM-EDX to identify the moieties attached to the surface. Membranes with open porosity ranging from 27% to 51% and average pore sizes from 0.2 to 1.4 μm were obtained. Samples sintered at 1400 °C with added pore former yielded the highest water flux, 257 Lm−2h−1, which increased to 642 Lm−2h−1 after functionalization. Membranes with tailored porosity and pore size obtained in this study are indicated for applications involving separation processes, especially for microfiltration systems.
