description: Why do armed rebel movements perpetrate reproductive violence against women in their own ranks? I argue that the answer to this question lies in the gendered makeup of rebel ideologies. Rebel masculinity and rebel femininity identify how men and women in armed rebel movements are expected to behave and contribute to their organization’s success. The ideology of a rebel movement identifies a shared vision for an ideal postconflict society – a vision that includes beliefs about how people of different genders ought to interact and contribute to society. Because rebels aim to embody those beliefs within the ranks of their organizations, I argue that expectations for how men and women ought to contribute to the group’s success are rooted in ideology. I also argue that these gendered expectations for behavior shape attitudes toward pregnancy because they prescribe how female rebels ought to contribute to the movement, and pregnancy may or may not align with those expectations. I evaluate the ideological commitments, gendered expectations for behavior, and attitudes toward pregnancy within the Revolutionary Armed Forces of Colombia and find support for these proposed causal mechanisms.
description: I also statistically analyze an original dataset on reproductive violence across armed rebel movements to test additional hypotheses. I find statistical support for my hypothesis that rebel movements with an ideological commitment to gender equality are more likely to perpetrate forced abortions against women in their own ranks. I argue that this is because gendered expectations for behavior within these types of rebel groups push women into nontraditional roles, such as combat or leadership positions, and pregnancy is seen as a threat to these expected contributions. I also find statistical support for my hypothesis that rebel movements with an ideological commitment to patriarchy are more likely to forcibly impregnate female rebels. I argue that this is because bearing and raising children align with the gendered expectations for behavior within these types of rebel movements. Importantly, I argue that male dominance and masculine authority over women and their bodies is preserved across rebel movements with different ideological commitments regarding gender relations, and this ultimately condones reproductive violence against female rebels. Variation in the types of reproductive violence rebels perpetrate, however, depends on their gendered ideologies.

description: In murine ontogeny, fetal liver is the major hemato- and B-lymphopoietic site until birth. Hematopoiesis develops in largely non-hematopoietic niches, which provide contacts, chemokines and cytokines that induce migration, residence, proliferation and differentiation of progenitors. Within early multipotent progenitors an IL7Rα+CSF-1R+ subset expressed a mixture of lymphoid- and myeloid-specific genes and differentiated to lymphoid and myeloid lineages in vitro. By contrast, IL7Rα+ cells were lymphoid-committed, and CSF-1R+ cells were erythro-myeloid-restricted. To respond to a multitude of chemokines single biphenotypic cells expressed CXCR4 and as many as five other chemokine receptors. The monopotent IL7Rα+ and CSF-1R+progenitors all expressed CXCR4, and mutually exclusive, more restricted sets of the analysed five chemokine receptors. This study proposes that chemokine polyreactive, cytokine-bipotent and monopotent progenitors transmigrate through LYVE-1high endothelium, attracted by selected chemokines, and reach the IL7- and CSF-1-producing ALCAMhigh mesenchymal niche, attracted by other sets of chemokines, to differentiate to B-lymphoid respectively myeloid cells.
Convergence reviews - or how monopolists extend their analogue empires
Creators: name: Marsden, Christopher
Publisher: name: Swinburne
Year: 2024

description: In this article I argue that monopolists have used the ‘threat’ of an upsetting of the media apple-cart to persuade politicians to grant them extended privileges in their analogue empires, both extending their reach into new markets in which they have (so far unsuccessfully) attempted to extend their dominance, and delaying the onset of real digital convergence. I do so via a review of the convergence reviews of the 1980s, 1990s and 2000s, focussing on the US and UK. It may provide some lessons for policymakers in the next policy cycle in convergence, intended as simply a warning from legislative and regulatory history. The UK will have a new Communications Bill published in 2012, and the US a general election later in the same year. Australia has concluded its review. I focus on the media mergers that took place in response to decline in the traditional media, focussing on Rupert Murdoch’s media empire, its newspaper monopoly in the UK and Australia and its growth as an analogue entrant into television in the UK and US. This is not simply in response to sensationalist recent coverage, but to the wealth of evidence of the undermining of media regulation uncovered by the Leveson Inquiry into the culture, practice and ethics of the press (Leveson 2012; Evans 2012; Murdoch 2012). I therefore examine convergence reviews from the realpolitik of the merger reviews which have created our media landscape, not the phoney wars of policy reviews (Collins 2010).

description: We report the 6dFGS Fundamental Plane (6dFGSv) catalogue that is used to estimate distances and peculiar velocities for nearly 9000 early-type galaxies in the local (z < 0.055) universe. Velocity dispersions are derived by cross-correlation from 6dF V-band spectra with typical S/N of 12.9 Å−1 for a sample of 11 315 galaxies; the median velocity dispersion is 163 km s−1 and the median measurement error is 12.9 per cent. The photometric Fundamental Plane (FP) parameters (effective radii and surface brightnesses) are determined from the JHK 2MASS images for 11 102 galaxies. Comparison of the independent J- and K-band measurements implies that the average uncertainty in XFP, the combined photometric parameter that enters the FP, is 0.013 dex (3 per cent) for each band. Visual classification of morphologies was used to select a sample of nearly 9000 early-type galaxies that form 6dFGSv. This catalogue has been used to study the effects of stellar populations on galaxy scaling relations, to investigate the variation of the FP with environment and galaxy morphology, to explore trends in stellar populations through, along and across the FP, and to map and analyse the local peculiar velocity field.

description: This thesis concerns Monte Carlo-based simulations of a scintillating glass detector for use in proton computed tomographic imaging (pCT). Currently, proton stopping power images of patients for use in proton radiotherapy are generated through stoichiometric calibration curves from x-ray CT images. However, proton range uncertainty introduced by x-ray CT to proton stopping power (SP) conversion is one of the primary barriers preventing proton therapy from reaching its full potential and utilization. A compact, relatively inexpensive calorimeter capable of accurately reconstructing a direct mapping of SP in a patient—and which can be mounted on the gantries of existing therapy suites—is proposed as a solution to this problem. With this detector, a filtered backprojection (FBP) algorithm that utilizes distance-driven binning is used to reconstruct images from a simulated proton pencil beam. These directly measured SP values are compared to those constructed from a new variation on a dual-energy CT (DECT) based CT-SP conversion scheme, benchmarking the performance of the proposed glass calorimeter against a competing method of determining patient stopping power. In this work, Monte Carlo simulations of pCT acquisitions of a commercial imaging phantom have been performed in the radiation transport code MCNP. These simulations model the aforementioned glass calorimeter as well as the imaging phantom, and images have been reconstructed using a modified implementation of a distance-driven filtered backprojection (FBP) algorithm developed specifically for proton pencil beams. Additionally, simulations of dual x-ray CT acquisitions with differing source spectra have been simulated in MCNP6 and reconstructed using a standard FBP algorithm, from which the phantom's SP values have been determined using a unique DECT-based CT-SP conversion scheme. The SP mappings acquired from the two different imaging modalities are compared to demonstrate the challenges that pCT with the proposed compact scintillating glass calorimeter must overcome in order to be competitive with other forms of SP determination in a clinical setting.

description: The first year of life is an important period for emergence of fear in humans. While animal models have revealed developmental changes in amygdala circuitry accompanying emerging fear, human neural systems involved in early fear development remain poorly understood. To increase understanding of the neural foundations of human fear, it is important to consider parallel cognitive development, which may modulate associations between typical development of early fear and subsequent risk for fear-related psychopathology. We, therefore, examined amygdala functional connectivity with rs-fcMRI in 48 neonates (M = 3.65 weeks, SD = 1.72), and measured fear and cognitive development at 6-months-of-age. Stronger, positive neonatal amygdala connectivity to several regions, including bilateral anterior insula and ventral striatum, was prospectively associated with higher fear at 6-months. Stronger amygdala connectivity to ventral anterior cingulate/anterior medial prefrontal cortex predicted a specific phenotype of higher fear combined with more advanced cognitive development. Overall, findings demonstrate unique profiles of neonatal amygdala functional connectivity related to emerging fear and cognitive development, which may have implications for normative and pathological fear in later years. Consideration of infant fear in the context of cognitive development will likely contribute to a more nuanced understanding of fear, its neural bases, and its implications for future mental health.
Altered methionine auxotrophy of a human melanoma cell line associated with exposure to serum.

description: The highly metastatic MeWo-LC1 cell line, derived from MeWo, the poorly metastatic human melanoma cell, exhibits a markedly reduced ability to synthesize DNA under conditions where methionine is replaced by 5$\sp\prime$-deoxy-5$\sp\prime$-methylthioadenosine in the medium. The difference in methionine auxotrophy between MeWo and MeWo-LC1 cells is not due to a lack of the enzyme necessary to degrade 5$\sp\prime$-deoxy-5$\sp\prime$-methylthioadenosine. However, when MeWo-LC1 cells are cultured in serum-free medium containing transferrin and supplemented with the nucleoside in place of methionine, DNA synthesis occurs normally. The presence of serum in the culture medium appears to alter the response of MeWo-LC1 cells to 5$\sp\prime$-deoxy-5$\sp\prime$-methylthioadenosine. The uptake of the nucleoside by MeWo-LC1 cells is not decreased in the presence of serum and therefore the substrate is likely to be available to the cell. Further, the incorporation of 5$\sp\prime$-deoxy-5$\sp\prime$-methylthioadenosine into cellular macromolecules appears to be unaffected by the presence of serum. However, under conditions where methionine is not limiting, the nucleoside has a greater inhibitory effect on DNA synthesis in MeWo-LC1 cells in the presence of serum than in serum-free medium supplemented with transferrin. The component(s) responsible for the inhibitory effect of serum on the 5$\sp\prime$-deoxy-5$\sp\prime$-methylthioadenosine-dependent synthesis of DNA remains elusive. (Abstract shortened by UMI.)

description: High-sensitivity radio-frequency observations of millisecond pulsars usually show stochastic, broadband, pulse-shape variations intrinsic to the pulsar emission process. These variations induce jitter noise in pulsar timing observations; understanding the properties of this noise is of particular importance for the effort to detect gravitational waves with pulsar timing arrays. We assess the short-term profile and timing stability of 22 millisecond pulsars that are part of the Parkes Pulsar Timing Array sample by examining intra-observation arrival time variability and single-pulse phenomenology. In 7 of the 22 pulsars, in the band centred at approximately 1400MHz, we find that the brightest observations are limited by intrinsic jitter. We find consistent results, either detections or upper limits, for jitter noise in other frequency bands. PSR J1909-3744 shows the lowest levels of jitter noise, which we estimate to contribute ~ 10 ns root mean square error to the arrival times for hour-duration observations. Larger levels of jitter noise are found in pulsars with wider pulses and distributions of pulse intensities. The jitter noise in PSR J0437-4715 decorrelates over a bandwidth of ~ 2 GHz. We show that the uncertainties associated with timing pulsar models can be improved by including physically motivated jitter uncertainties. Pulse-shape variations will limit the timing precision at future, more sensitive, telescopes; it is imperative to account for this noise when designing instrumentation and timing campaigns for these facilities.

description: We discuss the inherent challenges at the current frontier of quantum field theory (QFT), exploring both the well-known limitations of perturbative approaches and the less obvious limitations of non-perturbative approaches, both of which are exacerbated in many cases of particular interest such as in quantum chromodynamics. Motivated by the necessity-in-practice of using a field cutoff, we investigate the relatively unexamined theory of field operators of finite matrix rank, working within the simplest case of lattice \phi^{4} theory as an exemplar and toy model, and explain in detail how a finite operator results in a nonzero radius of convergence. The thesis then delves into the precise shape of the region of convergence in significantly more detail, introducing the concept of exceptional points and leveraging them to introduce a novel method of quickly estimating the radius of covergence of the weak-field perturbative series. In particular, we note that the positive real axis seems to be entirely clear of obstructions; the remainder of the thesis then details and implements a method to generate an analytic continuation of the model that includes both the weak- and strong-field limits, with good convergence throughout the otherwise inaccessible medium-coupling regime.

description: Older adults frequently experience a decrease in balance control that leads to increased numbers of falls, injuries and hospitalization. Therefore, evaluating older adults’ ability to maintain balance and examining new approaches to counteract age-related decline in balance control is of great importance for fall prevention and healthy aging. Non-invasive brain stimulation techniques such as transcranial direct current stimulation (tDCS) have been shown to beneficially influence motor behavior and motor learning. In the present study, we investigated the influence of tDCS applied over the leg area of the primary motor cortex (M1) on balance task learning of healthy elderly in a dynamic balance task (DBT). In total, 30 older adults were enrolled in a cross-sectional, randomized design including two consecutive DBT training sessions. Only during the first DBT session, either 20 min of anodal tDCS (a-tDCS) or sham tDCS (s-tDCS) were applied and learning improvement was compared between the two groups. Our data showed that both groups successfully learned to perform the DBT on both training sessions. Interestingly, between- group analyses revealed no difference between the a-tDCS and the s-tDCS group regarding their level of task learning. These results indicate that the concurrent application of tDCS over M1 leg area did not elicit DBT learning enhancement in our study cohort. However, a regression analysis revealed that DBT performance can be predicted by the kinematic profile of the movement, a finding that may provide new insights for individualized approaches of treating balance and gait disorders.
Evaluation of portable air quality sensors at the Vancouver (Clark Drive) near-road air quality monitoring site

description: This report describes evaluation of six low-cost, low-power air quality sensors and their comparison with co-located reference monitors at the Vancouver (Clark Drive) near-roadway air quality monitoring site operated by Environment Canada and Metro Vancouver. There has been a recent increase in awareness of public health issues associated with air quality combined with the development and availability of numerous low-cost, low-power air quality sensors. These sensors, and the ability of some models to be networked with data streaming to a central server offer the potential for less expensive air quality monitoring and enhanced spatial coverage. Furthermore, the commercial availability of these sensors offers non-regulatory bodies, researchers, and members of the public the possibility of near real-time access to additional air quality data, beyond that already provided by air quality management agencies. However, many of the companies producing these sensors have not compared their devices with regulatory grade monitors; hence, the accuracy, precision and stability of measurements from these sensors is not well understood. Understanding the performance of these devices is important for their use by non-regulatory bodies, researchers, and the general public, and for expanding their potential use for regulatory purposes.

description: We present stellar kinematics of 22 nearby early-type galaxies (ETGs), based on two-dimensional (2D) absorption line stellar spectroscopy out to ∼2-4 R e (effective radii), as part of the ongoing SLUGGS Survey. The galaxies span a factor of 20 in intrinsic luminosity, as well as a full range of environment and ETG morphology. Our data consist of good velocity resolution (σinst ∼ 25 km s-1) integrated stellar-light spectra extracted from the individual slitlets of custom made Keck/DEIMOS slitmasks. We extract stellar kinematics measurements (V, σ, h 3, and h 4) for each galaxy. Combining with literature values from smaller radii, we present 2D spatially resolved maps of the large-scale kinematic structure in each galaxy. We find that the kinematic homogeneity found inside 1 R e often breaks down at larger radii, where a variety of kinematic behaviors are observed. While central slow rotators remain slowly rotating in their halos, central fast rotators show more diversity, ranging from rapidly increasing to rapidly declining specific angular momentum profiles in the outer regions. There are indications that the outer trends depend on morphological type, raising questions about the proposed unification of the elliptical and lenticular (S0) galaxy families in the ATLAS3D survey. Several galaxies in our sample show multiple lines of evidence for distinct disk components embedded in more slowly rotating spheroids, and we suggest a joint photometric-kinematic approach for robust bulge-disk decomposition. Our observational results appear generally consistent with a picture of two-phase (in-situ plus accretion) galaxy formation.

description: The redox-active, labile iron pool (LIP) plays a role in oxidative stress in cancer cells. An elevated LIP and abnormal iron metabolism have been associated with poor survival in lung cancer by unknown mechanisms. To evaluate the LIP in non-small cell lung cancer (NSCLC) cells, the iron storage protein ferritin heavy chain (Ft-H) was over-expressed using a doxycycline-inducible lentiviral vector (pCMV6-XL4/5/6) system, and cells were treated with the iron chelator deferoxamine (DFO). Overexpression of Ft-H and DFO treatment decreased both LIP and clonogenic cell survival in H1299, but only DFO was effective in both H1299 and A549 NSCLC-cells. Overexpression of Ft-H also inhibited cell growth and delayed transit through S-phase; one of these effects was partially reversed by supplementing iron with holo-transferrin in H1299 cells. Overexpression of DFO and Ft-H also induced single- and double-strand DNA breaks and sensitized both H1299 and A549 NSCLC cells to inhibitors of the repair of DNA damage by targeting ATM and ATR signaling pathways. This suggests a role for Fe chelation-induced DNA damage and replication stress. Interestingly, overexpression of Ft-H and DFO were also able to sensitize both lung cancer cell lines to chemo-radiation. Overall, these results support of the hypothesis that reduction of the size of the LIP can induce DNA damage, replication stress, cell death, and potentiate therapeutic responses to chemo-radiation therapy in NSCLC.

Subjects: subject: Psychology, Clinical.

description: A total of 18 maritally-distressed couples, in which the female partner met diagnostic criteria for moderately severe clinical depression, were randomly assigned to Emotionally Focused Therapy (EFT) or to an individualized program of pharmacotherapy (PT) for the female partner. The purpose of the study was to examine the differential effectiveness of EFT, a systemic-experiential couple therapy, and PT in the prevention of relapse. Results suggest that both interventions were effective in reducing depression. Females in EFT were not depressed at follow-up but 2 females in PT did not respond to treatment. Marital adjustment increased significantly for females in EFT but not for their partners. The alleviation of depression in females in PT did not produce the hypothesized increase in their levels of marital adjustment, but their partners showed significant increases in their levels of marital adjustment. A differential pattern of relapse was not detected. Criteria for clinically-significant change suggest that females in EFT had better outcomes in terms of depression and marital distress, but that 2 couples in each group met the criteria of remitted depression and improvement in marital adjustment at 6-month follow-up. Results are discussed in light of an interpersonal approach to depression.

description: OBJECTIVE-Observational studies show breaking up prolonged sitting has beneficial associations with cardiometabolic risk markers, but intervention studies are required to investigate causality. We examined the acute effects on postprandial glucose and insulin levels of uninterrupted sitting compared with sitting interrupted by brief bouts of light- or moderate-intensity walking. RESEARCH DESIGN AND METHODS-Overweight/obese adults (n = 19), aged 45-65 years, were recruited for a randomized three-period, three-treatment acute crossover trial: 1) uninterrupted sitting; 2) seated with 2-min bouts of light-intensity walking every 20 min; and 3) seated with 2-min bouts of moderate-intensity walking every 20 min. A standardized test drink was provided after an initial 2-h period of uninterrupted sitting. The positive incremental area under curves (iAUC) for glucose and insulin (mean [95% Cl]) for the 5 h after the test drink (75 g glucose, 50 g fat) were calculated for the respective treatments. RESULTS-The glucose iAUC (mmol/L) . h after both activity-break conditions was reduced (light: 5.2 [4.1-6.6]; moderate: 4.9 [3.8-6.1]; both P < 0.01) compared with uninterrupted sitting (6.9 [5.5-8.7]). insulin iAUC (pmol/L) . h was also reduced with both activity-break conditions (light: 633.6 [552.4-727.1]; moderate: 637.6 [555.5-731.9], P < 0.0001) compared with uninterrupted sitting (828.6 [722.0-950.9]). CONCLUSIONS-Interrupting sitting time with short bouts of light- or moderate-intensity walking lowers postprandial glucose and insulin levels in overweight/obese adults. This may improve glucose metabolism and potentially be an important public health and clinical intervention strategy for reducing cardiovascular risk.

description: Brown Peril illuminates the discursive dynamics and development of South Asian anti-brownness in the early twentieth century United States. In this project, I argue brownness surfaces as a distinctly transnational rhetorical logic of racialization during the first half of the twentieth century to reconcile the entrance of South Asians on North American shores, emplacing them within maturing white supremacist racial hierarchies. While scholarship on brownness in Asian American studies often focuses on contemporary post-9/11 security culture, I argue anti-brown rhetoric, as a framework to articulate South Asians as racial threats, can be traced to early twentieth century public discourse with the arrival of South Asian Indians to North America. I build on scholarship on historical anti-Asian rhetoric that prioritizes a “yellow peril” framework, emphasizing East Asian subjects, by offering anti-brownness as a conceptual frame that more effectively accounts for the nuances of South Asian American racialization in the early twentieth century. Utilizing racial rhetorical criticism, I analyze archival materials, including newspapers from the early 1900s covering the arrival of South Asians in the U.S., a 1923 Supreme Court case that determined South Asian Indians could not access legal citizenship, and the first Hollywood films about South Asian Indians released during the Great Depression to reveal how rhetorics of South Asian racialization during this period are defined by a transnational visceral anti-brownness that functioned to proffer a public sense of fear and disgust towards South Asians marked in contrast to the rhetoric of “yellow peril.” I reveal the dimensions of a racialized public lexicon about South Asians that positions South Asian Indians as a “brown peril,” a threat that is unassimilable, incapable of accessing citizenship, and visually parodied as a transnational insurgent horde in defiance of colonial authority.
description: Ultimately, through an introduction and conclusion, along with a chapter on the global rhetorical history of brownness, and three case study chapters, I uncover how transnational, inter-imperial, and relational racial scripts guide, make legible, and assist in the production and cogency of anti-brownness as a form of anti-South Asian racism. I advance a theorization of South Asian anti-brownness to engage the complex relational rhetorical processes that underwrite the public accessibility of brownness as a racializing modality. Brown Peril highlights the transnational and inter-imperial dimensions of how anti-brownness becomes intelligible in early twentieth century U.S. public discourse through blackness, Indigeneity, and British coloniality and imperialism.
Selected heavy metal and organic removal from wastewater by precipitation and ozonation processes.

description: Experiments were conducted to precipitate dissolved copper, zinc, and lead from simulated wastewater solutions as solids which could then be separated by filtration. The precipitants used were hydrated lime, as a slurry and in powdered form, aqueous ammonium hydroxide, ferrous sulphide sludge, and carbon dioxide gas. These five different chemicals, singly or in combination, were used; at least one of which was highly successful in precipitating each of the metals, removing at least 99% of that originally present. Copper and zinc were very effectively precipitated as the hydroxides with lime, whereas lead was not. Considering lead to be the most difficult metal to remove, four other chemical conditions were attempted for lead; these were ferrous sulphide alone, lime with ferrous sulphide, lime with carbon dioxide, and lime with ozone. The precipitation of lead with ferrous sulphide alone, was only partially successful with only 95% removal. The other three combinations of chemicals precipitated more than 99% of the soluble lead, giving excellent results. Furthermore, because lead is usually difficult to remove from solution, it is considered that the three new chemical combinations show strong promise for the removal of other heavy metals from wastewater solutions. Experiments were also conducted to decompose the organic compounds, formaldehyde and pyridine, in simulated wastewater solutions in a mixed reactor, using ozone and UV radiation as oxidants. Although 200 ppm Total Organic Carbon content of each of those chemicals, and a mixture of both, were completely decomposed by ozone-UV oxidation, the time taken for these decompositions ranged from about three to four hours. Such prolonged reaction times are considered too long for most wastewater treating processes. However, low concentrations of organic matter might be successfully treated using ozone/UV processes.

description: Cette thèse propose d'aborder les tensions marquant les discours de la chanson québécoise. Elles sont articulées autour d'une quête d'appartenance et de liberté (Tully 1999). Abordant cette problématique depuis quatre " lieux " -- les trames interprétatives de la chanson québécoise, les propos de Gilles Vigneault, les oeuvres des Loco Locass et de Richard Desjardins -- il s'agit d'interroger les conceptions de la communauté politique et des identités qui y sont proposées et ce qu'elles indiquent quant aux modalités de la parole politique au Québec. Ces lieux apparaissent marqués par une tension entre un engagement critique multivoque et une insertion dans un récit de la communauté à tendance essentialiste ou consensuelle; ils correspondent à différentes inscriptions au sein de l'institution de la chanson. Considérant que les artistes sont engagés dans un vaste dialogue de (re)définition des communautés politiques, cette thèse souhaite amorcer une réflexion sur les tendances interprétatives d'une société -- sur ce qu'il est possible d'y dire et d'y faire entendre.

description: Background In order to validate if the test result of the Chemotherapy Resistance Test (CTR-Test) is able to predict the resistances or sensitivities of tumors in ovarian cancer patients to drugs, the CTR-Test result and the corresponding clinical response of individual patients were correlated retrospectively. Results were compared to previous recorded correlations. Methods The CTR-Test was performed on tumor samples from 52 ovarian cancer patients for specific chemotherapeutic drugs. Patients were treated with monotherapies or drug combinations. Resistances were classified as extreme (ER), medium (MR) or slight (SR) resistance in the CTR-Test. Combination treatment resistances were transformed by a scoring system into these classifications. Results Accurate sensitivity prediction was accomplished in 79% of the cases and accurate prediction of resistance in 100% of the cases in the total data set. The data set of single agent treatment and drug combination treatment were analyzed individually. Single agent treatment lead to an accurate sensitivity in 44% of the cases and the drug combination to 95% accuracy. The detection of resistances was in both cases to 100% correct. ROC curve analysis indicates that the CTR-Test result correlates with the clinical response, at least for the combination chemotherapy. Those values are similar or better than the values from a publication from 1990. Conclusions Chemotherapy resistance testing in vitro via the CTR-Test is able to accurately detect resistances in ovarian cancer patients. These numbers confirm and even exceed results published in 1990. Better sensitivity detection might be caused by a higher percentage of drug combinations tested in 2012 compared to 1990. Our study confirms the functionality of the CTR-Test to plan an efficient chemotherapeutic treatment for ovarian cancer patients.

description: The ionic and electronic contributions to the total magnetic susceptibility of a non ferromagnetic metal alloy are discussed, and a review of the experimental techniques for measuring susceptibilities is given. The presence of even small amounts of ferromagnetic impurities can have disastrous effects on the measured susceptibilities, and a method is described for correcting for such impurities when the Gouy method is used. This enabled the true susceptibility of the non ferromagnetic part of a substance to be determined with an accuracy of .1% relative to Ge. The room temperature values of magnetic susceptibility of the dilute alloys of Mn and Fe in Mg and Al were measured in view of obtaining information about the electronic configuration of the transition elements in solution. A localized d electron picture rather than a d band picture was found to be adequate. The measured effective Bohr magneton numbers yielded two possible electronic configurations for the solute atoms. The possibility of distinguishing between these is discussed in terms of the corresponding change in population of the conduction band and its influence on the electronic susceptibility.

Effect of nonsolvent additive on the surface morphology and the gas separation performance of poly(2,6-dimethyl-1,4-phenylene)oxide membranes.

description: Integrally skinned asymmetric membranes were prepared from poly(2,6-dimethyl-1,4-phenylene)oxide (PPO) using different nonsolvent additives. These nonsolvent additives consisted of branched and linear alcohols ranging from C3 to C10. Permeation data of these membranes were obtained from a constant pressure permeation system for pure gases Of CO2, CH4, O 2 and N2. An empirical correlation relating the pure gas permeance ratio of CO2/CH4 and the structural components of the nonsolvent additives has been proposed. The surface of the membranes was characterized by atomic force microscopy (AFM). It was observed that there were two types of surface morphologies: merged nodules and discrete nodules. The appearance of the nodules were reflected in the mean roughness data, Ra. It was revealed that membranes with smaller and merged nodules resulted in higher pure gas permeance ratios for O2/N2 and CO2/CH4 with the exception of 3,5,5-trimethyl-1-hexanol and 3-ethyl-2,2-dimethyl-3-pentanol. The microscopic studies showed that the membranes containing discrete nodules resulted in lower pure gas permeance ratios for O2/N2 and CO2/CH4. It was observed that nonsolvent additives that possess a long straight hydrocarbon chain such as 2-ethyl-1-hexanol, 1-octanol and 2-decanol produced the highest pure gas permeance ratios. The polymer solutions from which the membranes were made were characterized through intrinsic viscosity and surface tension measurements. The intrinsic viscosity studies revealed that as the intrinsic viscosity increased, the chances of entanglement of the polymer molecules increased. As a result, the pure gas permeance for CO2/CH4 increased with the exception of 3,5,5-trimethyl-1-hexanol. The surface tension studies showed that as the surface tension of the solutions increased, the pure gas permeance for CO 2/CH4 and O2/N2 increased. This was due to the increase of the capillary forces within the spherical particles of the polymer-rich phases. Plasma-etching is a powerful tool for investigating the structure of the skinlayer of asymmetric membranes. This process involves the gradual etching of the skinned membrane surface by highly reactive particles from an oxygen gas plasma. The rate of etching was low at 0.1 x 10--6 m/min. The membranes were etched at 30, 60, 120 and 190 sec. Pure gas permeances using CO2, CH4, O2 and N2 were determined for the etched and unetched membranes. The morphology of these membranes was determined from scanning electron microscopy (SEM) and atomic force microscopy (AFM). SEM of the cross-section of the membranes showed that there is a transition in the membrane structure from the dense layer to the layer with visible pores. AFM images of the top surfaces of the membranes showed that mean roughness of the nodules increased linearly as the membrane is exposed to longer periods of etching time.

description: The down-regulation of CD4 by cultured monocytes has been observed by our group and by other investigators. Flow cytometric analysis was performed to elucidate factors influencing this phenomenon. The addition of LPS, GM-CSF, M-CSF or IL-10 to monocyte cultures failed to inhibit the decrease in monocyte CD4 expression following overnight culture. The down-regulation was an adherence-independent phenomenon since it was not prevented by culture in Teflon vials. The type of anticoagulant into which the peripheral blood was collected did not appear to be a factor, The presence or absence of lymphocytes within the cultures was also inconsequential. The continued culture of monocytes in a whole blood environment resulted in decreased CD4 down-regulation. Experiments in which CD4 was tagged with alpha-CD4-PE mAb prior to cell culture revealed that the down-regulation observed was the result of CD4 internalization. In an attempt to further understand monocyte CD4 function, we investigated the role of monocyte CD4 in signal transduction. Stimulation of Thp-1 monocytic cells with antibody to CD4 resulted in a Ca2+ flux, as well as in the time-dependent tyrosine phosphorylation of various proteins having molecular weights of approximately 180, 140, 120, 110, 85, 65, 55, 50 and 35 kDa. We identified the 140 and 85 kDa proteins as PLC-gamma1, and the regulatory subunit of PI3-K, respectively. Using immunoprecipitation/Western immunoblotting, we were unable, however, to show any direct association between CD4 and PLC-gamma1, PI3-K, or other signaling proteins. In an attempt to identify proteins capable of associating with the cytoplasmic tail of CD4, we generated a GST-CD4cyt fusion protein for use in far Western blots and immunoprecipitation experiments. In both types of experiments, the GST-CD4cyt fusion protein routinely associated with 45 and 55 kDa proteins. In the immunoprecipitation experiments, a 35 kDa protein was also observed. The above results suggest that the expression of monocytic CD4 is regulated during the differentiation process. Furthermore, the cytoplasmic tail of monocytic CD4 is associated with various proteins which we postulate function in signal transduction, and which may also play a role in CD4 down-regulation.

description: In mid-2022, the Large Hadron Collider (LHC) at CERN began Run 3. In this investigation, the LHC will produce proton-proton collisions at the energy of 13.6 TeV, in collaboration with the CMS experiment, to search for significant evidence of the Standard Model Higgs boson decaying to two muons. Specifically, our group will search for this interaction via the vector boson fusion (VBF) channel.
description: Furthermore, upgrades to CMS need to be performed in preparation for the High-Luminosity Large Hadron Collider (HL-LHC) project. Specifically, the CMS Outer Tracker (OT) will now be able to single out beam crossings with tracks in excess of 2 TeV of transverse momentum and associate physics objects with the high transverse-momentum tracks. The OT will replace the strip tracker and is expected to operate for nearly a decade without any needs for repairs. These operations will be partially conducted at the Fermi National Accelerator Laboratory located just outside Batavia, Illinois. The Fermilab OT group is responsible for the assembly and testing of over 1,250 PS modules and 1000 2S modules. Overall, in combination with
