description: In this paper, we carry out the next-to-leading-order QCD corrections to $Z \to η_Q+g+g~(Q=c,b)$ (labeled as $gg$) through the color-singlet (CS) state of $Q\bar{Q}[^1S_0^{[1]}]$, with the aim of assessing the impact of this process on $Z$ bosons decaying into inclusive $η_Q$. We find that the QCD corrections to the $gg$ process can notably enhance its leading-order results, especially for the $η_c$ case, which would then greatly increase the existing predictions of $Γ_{Z \to η_Q+X}$ given by the CS-dominant process $Z \to η_{Q}[^1S_0^{[1]}]+Q+\bar{Q}$. Moreover, with these significant QCD corrections, the $gg$ process would exert crucial influence on the CS-predicted $η_Q$ energy distributions. In conclusion, in the CS studies of $Z \to η_Q+X$, besides $Z \to η_{Q}[^1S_0^{[1]}]+Q+\bar{Q}$, $Z \to η_Q[^1S_0^{[1]}]+g+g$ can provide phenomenologically indispensable contributions as well.

description: Large-scale Bundle Adjustment (BA) requires massive memory and computation resources which are difficult to be fulfilled by existing BA libraries. In this paper, we propose MegBA, a GPU-based distributed BA library. MegBA can provide massive aggregated memory by automatically partitioning large BA problems, and assigning the solvers of sub-problems to parallel nodes. The parallel solvers adopt distributed Precondition Conjugate Gradient and distributed Schur Elimination, so that an effective solution, which can match the precision of those computed by a single node, can be efficiently computed. To accelerate BA computation, we implement end-to-end BA computation using high-performance primitives available on commodity GPUs. MegBA exposes easy-to-use APIs that are compatible with existing popular BA libraries. Experiments show that MegBA can significantly outperform state-of-the-art BA libraries: Ceres (41.45$\times$), RootBA (64.576$\times$) and DeepLM (6.769$\times$) in several large-scale BA benchmarks. The code of MegBA is available at https://github.com/MegviiRobot/MegBA.

description: LiDAR (short for "Light Detection And Ranging" or "Laser Imaging, Detection, And Ranging") technology can be used to provide detailed three-dimensional elevation maps of urban and rural landscapes. To date, airborne LiDAR imaging has been predominantly confined to the environmental and archaeological domains. However, the geographically granular and open-source nature of this data also lends itself to an array of societal, organizational and business applications where geo-demographic type data is utilised. Arguably, the complexity involved in processing this multi-dimensional data has thus far restricted its broader adoption. In this paper, we propose a series of convenient task-agnostic tile elevation embeddings to address this challenge, using recent advances from unsupervised Deep Learning. We test the potential of our embeddings by predicting seven English indices of deprivation (2019) for small geographies in the Greater London area. These indices cover a range of socio-economic outcomes and serve as a proxy for a wide variety of downstream tasks to which the embeddings can be applied. We consider the suitability of this data not just on its own but also as an auxiliary source of data in combination with demographic features, thus providing a realistic use case for the embeddings. Having trialled various model/embedding configurations, we find that our best performing embeddings lead to Root-Mean-Squared-Error (RMSE) improvements of up to 21% over using standard demographic features alone. We also demonstrate how our embedding pipeline, using Deep Learning combined with K-means clustering, produces coherent tile segments which allow the latent embedding features to be interpreted.

description: To conduct spin-sensitive transport measurements, a non-local device geometry is often used to avoid spurious voltages that are caused by the flow of charges. However, in the vast majority of reported non-local spin valve, Hanle spin precession, or spin Hall measurements background signals have been observed that are not related to spins. We discuss seven different types of these charge-induced signals and explain how these artifacts can result in erroneous or misleading conclusions when falsely attributed to spin transport. The charge-driven signals can be divided into two groups: Signals that are inherent to the device structure and/or the measurement setup and signals that depend on a common-mode voltage. We designed and built a voltage-controlled current source that significantly diminishes all spurious voltage signals of the latter group in both DC and AC measurements by creating a virtual ground within the non-local detection circuit. This is especially important for lock-in-based measurement techniques, where a common-mode voltage can create a phase-shifted, frequency-dependent signal with an amplitude several orders of magnitude larger than the actual spin signal. Measurements performed on graphene-based non-local spin valve devices demonstrate how all spurious voltage signals that are caused by a common-mode voltage can be completely suppressed by such a current source.

description: Human adenovirus (Ad) grows efficiently in most cultured human cells (HeLa) but grows poorly in cell lines derived from African green monkey kidney cells (CV-1). During abortive Ad infections of CV-1 cells, expression of the virally encoded fiber protein is blocked at the translational level. Ad2$\sp+$ND5 is a hybird virus in which a nonessential region of the adenovirus genome has been deleted and a portion of the SV40 genome inserted. The SV40-specific 42kd protein produced by Ad2$\sp+$ND5 is also regulated in a posttranscriptional manner similar to that of the Ad fiber protein.  The block to replication of these viruses can be overcome by culture of CV-1 cells under modified conditions, by coinfection with an Ad host range (hr) mutant, or by coinfection with simian virus 40 (SV40). Fiber and the 42kd protein are efficiently synthesized during the resulting permissive infections. Correlated with a productive infection and efficient synthesis of fiber protein is an alteration in the splicing pattern of fiber message such that 10 to 25 percent of fiber messages contain the x" or "y" ancillary leader in addition to the tripartite leader common to all late viral messages. In contrast, during abortive infections very little of the fiber mRNA carries either ancillary leader, suggesting that these sequences may be necessary for efficient translation.  The translational activity of each class of fiber message was assessed. The presence of the "y" leader in productively infected cells increases the rate of initiation. Elongation is similar on all fiber messages in productively infected cells; however, the rate of elongation of these messages is about threefold slower in abortively infected cells. This reduced elongation is specific for fiber. The similar distribution of fiber mRNAs on polysomes in both infections suggests that initiation must also be partially blocked in abortive infections. Since the majority of the fiber mRNA even in productive infections do not contain the ancillary leaders, the initiation and elongation defects in the abortive infection cannot be fully explained by the absence of these leaders. Therefore, other factors in the infected cell must be influencing the rate of translation.

description: This paper considers the sociocultural support system of 20 elderly Mexican-American people.  The purpose of the research was to describe the properties of the sociocultural support system according to the structural availability and opportunity for support and the international or supportive bonds within the support system.  Also considered was the effect of the system of health and health care as well as transcultural nursing care implications in relation to the elderly Mexican-American and his support system.  It was found that the informants' supportive contracts were formed on the basis of proximity, kinship and ritual kinship ties, long-standing friendship, and church affiliation.  Their supportive interactions consisted of (1) positive interpersonal exchanges, (2) intimacy, (3) self-care through interaction with other, (4) shared norms and experiences, (4) rituals, and (6) instrumental support.  The support system appeared to have a positive effect on health and care in several interrelated ways, including (1) provision of group membership and ongoing simulating relationships that entail significant physical and social activity that could help to eliminate depression, (2) access to a structure where useful role activities are available, (3) provision of economic and health care interventions that decrease need for institutional care, and (4) an emphasis on values reflecting interdependence and sharing of material and social resources especially among family members.  Collaboration between the professional health care system and the sociocultural support system was discussed and encouraged as a way to provide more effective and culturally appropriate health car

description: The purpose of this study was to assess treatment and medication compliance in the adolescent population with asthma. The Asthma Compliance Questionnaire (ACQ) was used to collect data from 48 adolescents with asthma. The data were collected from multiple clinic sites, and a mail survey was tested. Using the logistic regression model, the compliance of adolescents with asthma was predicted on the basis of energy and willpower, motivation, and support from parents. The most powerful predictors were energy and willpower. Adolescents with energy and willpower were 467.939 times more likely to take care of themselves and to comply with health regimens than adolescents without energy and willpower. The next predictor of compliance was motivation. Adolescents with motivation were 17.2455 times more likely to comply with health regimens than adolescents without motivation. In addition, adolescents with parental support were 4.2567 times more likely to comply with health regimens than adolescents without support.

In vivo effects of ftorafur and fluorouracil on mammary tumors and small intestine in mice.

Publisher: name: University of Utah
Year: 2012
Subjects: Intestine, Small
Cells, Cultured

description: The in vivo effects of Ftorafur (FT) and 5-fluorouracil (FU) were evaluated at several different organizational levels within the same animal model.  On a molar basis, FU was found to be two to three times more potent than FT with respect to growth inhibition of murine mammary adenocarcinomas.  However, administration of FT produced less host toxicity at a dose level which resulted in similar antitumor activity.  Drug-induced perturbations in cell cycle phase distributions were analyzed by the flow cytometer (FCM).  Although FCM analysis is limited by lack of information on the extent of dead and dying cells, data obtained with both drugs were consistent with the possibility of S phase cytotoxicity and drug-induce G1/S block or delay.  Changes in the age distribution of perturbed tumor cells, is detected by FCM analysis, correlated with 3H-TdR autoradiography and with 32P incorporation into DNA but not with 3H-deoxyuridine incorporation into DNA.  Both drugs depressed 3H-deosyuridine incorporation into DNA; however, incorporation in both the tumor and small intestine returned to control levels earlier with FT than with an equimolar dose of FU.  However, both drugs produced similar patters of 3H-deoxyuridine incorporation when FT was administered at three times the molar equivalent dose of FU.  The results of these studies also suggest that deoxyuridine incorporation primarily reflects drug effects on thymidylate synthetase and not necessarily the overall rate of DNA synthesis.  This study also involved the development of techniques for the dispersal of solid tumors and intestinal lining epithelium into single cell suspensions for FCM analysis.  Tetraphenylboron (TPB) was utilized as an aid to solid tumor dispersal.  TPB-dispersed tumors yield DNA distributions with minimal cell clumping and low levels of cellular debris. Fluorescent enzyme histochemistry with subsequent FCM analysis was utilized to separate dispersed epithelial cells of the small intestine into crypt and villus subpopulations. When fully optimized, the epithelial cell separation should offer a rapid method by which perturbations in the age distribution of crypt cells can easily be evaluated by FCM.

description: Trekkers exposed to prolonged hypobaric hypoxia commonly experience weight loss, especially loss of lean body mass (LBM). Evidence indicates that protein supplementation, specifically leucine, potentially attenuates loss of LBM in a catabolic state. This study investigated if leucine supplementation would prevent the loss of LBM during prolonged hypoxia. 18 trekkers (M=10 and F=8; age: 47.2 ± 11.5; range: 28-70y), completed a 13-day trek in Nepal from Lukla (2180m) to Everest Base Camp (5364m) with a mean altitude of 4140m. Participants consumed a 7.0g leucine supplement or an isocaloric, isonitrogenous placebo twice daily prior to meals. Body composition, body weight, and circumferences of bicep, thigh, and calf were taken pre- and post-trek. The participants from both treatments experienced significant loss of LBM and weight loss after 13 days at altitudes above 2810m (P< 0.05). However, there was no difference in loss of LBM (leucine -1.2 ± 1.6%; placebo -2.1 ± 1.5%), body weight (leucine -2.2 ± 1.5%; placebo -2.3 ± 2.0%), or circumferences between the groups. Overall, our results indicate that under the conditions of this study, leucine did not significantly reduce LBM loss during 13 days of altitude-induced hypoxia. This study was funded by Glanbia Nutritionals.

description: A computer-controlled air pump, developed to simulate spirometry, was used to inject standard waveforms in order to comprehensively evaluate 53 currently available spirometers.  The pump generated spirometry waveforms reproducible to within +30 ml over a 6.0 1 volume range.  Evaluation of spirometry systems was conducted in four areas: (1) manuals and reference materials, (2) operation procedures, (3) static testing with a 3.0 1 calibrating syringe, and (4) dynamic testing with a spirometry simulator.  Manuals were examined to determine the inclusion of applicable material.  Operational assessment evaluated the useability, maintenance requirements, and cost of operation of each spirometer.  Static evaluation was performed using a precision 3.0 1 calibrating syringe to determine volume measuring accuracy.  Volume measuring ability was tested at slow and fast syringe emptying rates. In addition, volume-based spirometers were tested with two different starting volumes.  Dynamic testing involved injecting 24 standard waveforms into the spirometers to determine the ability to measure actual patient procedures. A record was made of the ability of spirometers to measure A record was made of the ability of spirometers to measure FVC (forced vital capacity), FEVl (forced expiratory volume in one second), FEFmax (maximum expiratory, or peak, flow), and FEF25.75% (mean forced expiratory flow during the mid 50% of exhaled volume).  Results from dynamic testing were matched against performance requirements of the American Thoracic Society (ATS) published in 1979 and updated in 1986.  Using the 1986 requirements, 26 devices (49%) were found that measured three spirometry parameters acceptably (FVC, FEVX, and FEF25.75%), 1 (2%) was conditionally acceptable, 9 (27%) were marginally acceptable, and 18 (34%) failed.  The evaluation process disclosed software errors in 15 out of 50 automated systems (30%).  Most manufacturers responded promptly and submitted systems with corrected software.  The state of current spirometer technology shows overall improvement when compared to earlier systems.  The percentage of volume-based devices found to be acceptable improved from 67% to 72%; acceptable flow-based spirometers improved remarkably from 0% to 54%, when application of 1979 ATS performance standards determined acceptability. More stringent 1986 ATS standards showed that 66% of the volume and 33% of the flow devices were acceptable.

description: This research consists of the biographies of four women who practiced nurse-midwifery during the first forty years of the profession's existence.  Analysis of the biographical information reveals that the four subjects share many similar characteristics.  It is postulated that these shared characteristics led to the particular response which each woman made to the challenges she met in the course of her career; each of these nurse-midwives created structures designed to meet the urgent needs of mothers and babies in this country for adequate health care.  The accomplishments of the four nurse-midwives are examined in light of the changes in childbirth practices which occurred in the first half of the twentieth century.

Publisher: name: University of Utah
Year: 2012
Subjects: Myocardium

description: The alkylating agent bromoacetylalprenololmenthane (BAAM), which selectively binds beta-adrenergic receptors, was used to determine if human ventricular myocardium contains "spare" beta-receptors. Decreases in beta-receptor density were compared to changes in agonist stimulated adenylate cyclase activity and isolated muscle contractility with and without BAAM treatment. In membrane preparations, BAAM produced concentration-dependent decreases in beta-receptor density and adenylate cyclase activity. In right ventricular trabeculae from nonfailing and failing human hearts, BAAM produced modest decreases in contractile force. These results imply a lack of a detectable pool of  "spare" beta-adrenergic receptors in membrane preparations when the pharmacological endpoint is adenylate cyclase activity. However, the presence of a small pool of "spare"' beta-adrenergic receptors in isolated muscle strips cannot be ruled out when the endpoint is contractile response. We used primary cultures of embryonic chick and frog myocardial cells to determine their usefulness as model systems for the eventual study of the long-term influences of catecholamines on beta-receptor pathways. Using nonlinear regression analysis, chick beta-receptors modeled for a single low affinity site based on both ICYP/betaxolol (beta1-selective) and ICYP/ICI-118551 (beta2-selective) competition curves indicating that beta-avian is neither beta1or beta2. With CGP 20712A (beta1-selective), the chick modeled for two sites, a high affinity "beta1-like" site, and a low affinity "beta2-like"' site. Also, the relative ability of agonists to displace ICYP was "beta1-like," with a rank order of potency being isoproterenol > epinephrine ? norepinephrine. For adenylate cyclase stimulation, norepinephrine was slightly less potent than epinephrine suggestive of a low affinity "beta2-like" component for norepinephrine. ICYP/antagonist competition curves in frog myocardial cells modeled for a mixed population of receptors, the subtype percentages varying from 50% to 100% beta2 depending on the antagonist used and the individual cell preparation. In agonist competition curves, the relative ability to displace ICYP was isoproterenol > epinephrine ? norepinephrine. However, in terms of their ability to stimulate adenylate cyclase activity, the order of potency was isoproterenol > epinephrine > norepinephrine, more suggestive of the presence of beta/2 receptors. Both chick and frog myocardial cells appear to be useful models for studying the effects of catecholamines on beta-receptor pathways if certain limitations are recognized.

description: Over the last century, wild Atlantic salmon populations have been in steep decline. Historically, fish populations have deteriorated primarily from overfishing. In the case of wild Atlantic salmon populations, the decline in the population comes from the result of spreading diseases derived from aquaculture. The crux of this thesis focuses on the aquaculture industry in Scotland, because of the rapid and unique development of the aquaculture industry and the effect it has had on wild salmon populations. This thesis will determine the costs aquaculture have had on wild salmon recruitment, as well as the costs aquaculture has had on related industries (primarily recreational angling). Through the analysis of the thesis, there will be a review of two possible policy actions that can be taken to promote abatement and maximize social welfare of the damages. The two policy actions in question will be the use of a penalty tax and the use of marketable permits by authorities.

History

description: Zionism in Zion: Salt Lake City's Jewish Community and Israel, 1933-1967  seeks to understand how Zionism and the creation of the state of Israel affected a Jewish  community in the western United States. It will be argued that the Salt Lake City Jewish community followed national trends in their interest in and formation of Zionist organizations and that Zionist activity was shaped by religious and other influential community leaders. "Zionism in Zion" also touches upon the unique connection between  Jews and Mormons. The thesis is organized into four chapters: a historical description of  the Jewish community's origins and growth, principle leaders of Salt Lake Zionism, Salt  Lake Hadassah chapter activities, and the impact of visiting Zionist speakers and other  community activities. The conclusion seeks to place the Zionist movement within a  global context. Source material is located primarily at the University of Utah Marriott  Library Special Collections, specifically the Jewish Archives, and the Louis C. Zucker  and Benjamin M. Roe papers. Monthly Hadassah minutes are in the possession of Karen  McArthur and Helene Cuomo. During the years in consideration, regional, national and  international Zionist leaders visiting Salt Lake City received substantial press coverage.  In addition, interviews with Fred Tannenbaum, Joel Shapiro, and Esther Landa were  especially useful.

description: A computerized system for infection surveillance data storage and reporting was developed using the HELP computer system at LDS Hospital in Salt Lake City, Utah.  Provision was man for the storage of five years of these data on disk.  Infection information was entered directly into the patient data records from which computerized monthly and quarterly reports were run.  This system saved the infection control practitioners at the hospital an estimated twenty-three hours per month in surveillance time.  A second part of the work was a study performed to determine the effectiveness of using hospital-wide monthly culture rates to 1) monitor the nosocomial infection rate, 2) predict infection rates for the following month, or 3) detect nosocomial infection outbreaks.  Correlations were performed between monthly culture rates and the nosocomial infection rates for the same month and between culture rates and the infection rates for the following month.  Finally, the culture rates for months involving actual infections outbreaks were compared to the average culture rate and an upper 95% confidence interval to test the usefulness of culture data in detecting outbreaks.  The results of the study indicated that hospital-wide monthly culture data were no reliable in monitoring infections rates for the same month, in detecting the infection rate for the following month or in detecting outbreaks.

description: In this paper, we give a systolic inequality for a quotient space of a Carnot group $Γ\backslash G$ with Popp's volume. Namely we show the existence of a positive constant $C$ such that the systole of $Γ\backslash G$ is less than ${\rm Cvol}(Γ\backslash G)^{\frac{1}{Q}}$, where $Q$ is the Hausdorff dimension. Moreover, the constant depends only on the dimension of the grading of the Lie algebra $\mathfrak{g}=\bigoplus V_i$. To prove this fact, the scalar product on $G$ introduced in the definition of Popp's volume plays a key role.

Recognition of ubiquitin-conjugates by the 26S protease

description: Multiubiquitination is a key step leading to the selective degradation of abnormal polypeptides and many important regulatory proteins by a large multisubunit enzyme--the 26S protease. However, the mechanism by which ubiquitin-conjugates are recognized by this enzyme is unknown. I used a protein binding assay to identify a subunit (S5a) of the 26S complex that binds multiubiquitinated lysozyme. S5a associates with free multiubiquitin chains--a result consistent with the hypothesis that attachment of a multiubiquitin chain to a protein targets it for destruction by the 26S protease. In addition, the affinity of S5a for ubiquitin polymers increases with increasing chain length, providing a possible explanation for the preference of the 26S protease for substrates conjugated to longer multiubiquitin chains. The biochemical properties of S5a inspired a model in which repeated binding domains in the subunit confer the ability to select for multiubiquitin chains. In support of this idea, the cDNA for S5a encodes a protein containing repeated sequences. Addition of S5a to in vitro extracts specifically inhibits proteolysis of both artificial and natural substrates of the ubiquitin pathway. These data suggest that S5a will serve as a valuable reagent for assessing the involvement of ubiquitin-mediated proteolysis in a variety of cellular events.

Una delle teorie formulate per spiegare la misteriosa natura della materia oscura prevede che questa abbia le sembianze di buchi neri primordiali. Secondo un nuovo studio condotto da un gruppo di ricercatori del Massachusetts Institute of Technology, per verificare questa ipotesi bisognerebbe monitorare Marte, la cui orbita potrebbe essere perturbata dal passaggio di questi buchi neri microscopici.

description: Measurement-rich power distribution networks may enable distribution system operators (DSOs) to adopt model-less and measurement-based monitoring and control of distributed energy resources (DERs) for mitigating grid issues such as over/under voltages and lines congestions. However, measurement-based monitoring and control applications may lead to inaccurate control decisions due to measurement errors. In particular, estimation models relying on regression-based schemes result in significant errors in the estimates (e.g., nodal voltages) especially for measurement devices with high Instrument Transformer (IT) classes. The consequences are detrimental to control performance since this may lead to infeasible decisions. This work proposes a model-less robust voltage control accounting for the uncertainties of measurement-based estimated voltage sensitivity coefficients. The coefficients and their uncertainties are obtained using a recursive least squares (RLS)-based online estimation, updated whenever new measurements are available. This formulation is applied to control distributed controllable photovoltaic (PV) generation in a distribution network to restrict the voltage within prescribed limits. The proposed scheme is validated by simulating a CIGRE low-voltage system interfacing multiple controllable PV plants.
