description: Infertility is a significant and growing problem that affects about 12% of couples in the US. The strongest reason for this issue is a combination of the inevitable limitation of aging on fertility and the social tendency for couples to wait longer until they have children. Out of the about seven million women affected by infertility, 40% of them experience problems due to a dysfunction in ovulation. Ovulation is the culmination of a long process of follicle growth and maturation, termed folliculogenesis, in the ovaries. The main hormone responsible for driving folliculogenesis is the pituitary gonadotropin follicle-stimulating hormone (FSH). Local factors secreted in the follicle also play an important role for proper follicle maturation. One such factor is insulin-like growth factor (IGF). We have shown that the activity of the IGF1 receptor (IGF1R) is necessary and required for proper follicular response to FSH. Accordingly, high follicular levels of IGF in patients seeking assisted reproductive technologies, such as in vitro fertilization (IVF), are associated with a better response to FSH and better embryo quality. The exclusive target of FSH in the follicle are the granulosa cells (GCs) that surround the oocyte. FSH, through cAMP signaling, causes GC differentiation leading to their production of aromatase, an enzyme that converts androgens to estradiol. GC differentiation is required for follicle maturation, without which the follicle fails to develop and ovulate. A lack of IGF1R activity in GCs renders them unable to respond to FSH, and they fail to produce aromatase. Based on this, we postulated that IGF augments GC differentiation by inhibiting a negative regulator of FSH. Previous work in the lab has shown that IGF1R and FSHR activity converge on the activation of AKT, however, the downstream signals linking AKT to GC-differentiation are unknown. We hypothesized that the salt inducible kinases (SIKs), which are known to be inhibited by AKT and are known inhibitors of cAMP signaling, limit the response of the GCs to FSH. Here, I show that SIKs inhibition in GCs augments their response to FSH and production of aromatase in vitro and in vivo. I also investigate the placement of SIKs activity within the FSHR/IGF1R pathway. By understanding the signaling components that control follicle maturation, we can contribute to alleviating the emotionally and financially taxing problem of infertility.

description: Circulating tumor cells (CTCs) are exceedingly rare cancer cells shed from tumors into the bloodstream, where they have the potential to invade other tissues to seed metastases. CTCs are difficult to isolate but their critical role in tumor metastasis, as well as their proven prognostic value has attracted tremendous interest in recent years. While many methods have been developed to isolate CTCs, a major bottleneck to their clinical application has been the precise identification and characterization of these cells, owing to their tremendous phenotypic heterogeneity. To address these formidable challenges, a number of microscopy techniques have been applied to gather large amounts of information about captured cells. However, these studies are currently limited by two major concerns: First, due to the phenotypic plasticity of tumor cells, there may be significant variability in the properties of CTCs as observed using microscopy. Second, if the CTCs are subjected to multi-parameter analysis, the high-content data may be too expansive to analyze with a reasonable amount of time and effort. In this thesis, I developed an efficient and customizable spectral image cytometry platform to collect multi-spectral data from immunofluorescence micrographs of cell samples enriched for CTCs in order to quickly and easily analyze this information to facilitate CTC identification and characterization. This work includes the development of software tools to convert microscopy data for processing, to segment the images into single cell images, to rank potential CTCs, and to provide a user interface for rapid augmented review. The performance of this software platform has been evaluated by analyzing multi-spectral fluorescence imaging data previously collected by our group from ten patients with castrate resistant prostate cancer, and then comparing the result to unassisted manual reviews performed by blinded reviewers. The final CTC identification counts closely matched manual analysis with a slight increase in verified CTC counts, which is likely a result of the comprehensive nature of the automated screening process. The average computation time is 4.5 minutes per sample, which is faster than the time required to acquire the imaging data, and thus allows operators to quickly review results between acquisitions.

description: The distributed Bragg reflectors (DBRs) are important optical components in a wide range of applications, such as Fabry-Perot optical resonators, hyperspectral sensors, micro-cavity structures, and waveguide lasers. In this thesis, we have developed, designed, and fabricated highly reflecting, and mechanically stable DBRs comprised of electron-beam deposited zinc selenide (ZnSe) and barium fluoride (BaF2) thin films and explored its use in optical filtering and hyperspectral sensing applications. Most published results are in the short-wavelength infrared (SWIR) and near-infrared (NIR) with limited results in the mid-wavelength infrared (MWIR). In this work, we have fabricated ZnSe/BaF2-based DBRs in the MWIR region. The fabricated DBRs showed a central wavelength of 4 µm and reflection exceeding 93%. A Fabry-Perot optical filter, that is comprised of two parallel DBR mirrors with half-wavelength optical cavity thickness was used to partially transmit and reflect the incident light at the target wavelength. The assembled fixed-cavity Fabry-Perot optical filters achieved a full-width half maximum (FWHM) of ~ 450 nm. We further showed that the FWHM of the optical filters can be reduced by ~ 50 % with the addition of nano-thick silicon monoxide (SiO) interface grading layer between every pair of the quarter-wave optical thick (QWOT) layers in the stack. The SiO interface grading layer acts as an anti-reflection coating layer to reduce reflection loss in the DBR multilayer structure. The SiO interface grading layer, ~ 80 nm thick, also has the potential to stop atomic inter-diffusion between the layers to minimize free carrier absorption loss. The principal thesis goal is to design and assemble fixed-cavity interface-graded Fabry-Perot optical filters (with SiO interfacial layers) that optimized optical transmission and spectral resolution. The thesis also proposes a low-cost micro-cavity structure that can be formed by embedding two-dimensional atomic crystals, such as black phosphorous into a DBR cavity structure. The proposed design can be used to increase absorption in 2D materials, which has the potential to increase the efficiency of next generation MWIR photodetectors and infrared sensors.
Characterization of Dermal Exposure as a Result of Glove Penetration

description: Dermal exposure is a primary route of occupational chemical exposure. Contact dermatitis, a highly prevalent health outcome associated with dermal exposure, is one of the most common occupational illnesses and affects millions of workers each year. Chemically resistant gloves are the primary control method used to protect against dermal exposure. Glove assessment focuses on laboratory-based studies of chemical permeation, and these data are used to select gloves that have long break-through times for the chemical of concern. There, are however, alternative mechanisms of glove failure that can lead to dermal exposure. A study of dermal exposure to the hands resulting from glove penetration was carried out using an experimental simulation approach with two different glove types (short-cuff and long-cuff nitrile gloves). Simulations consisted of 20 participants using gloves to wash glassware in a tub of fluorescein solution. The first 10 participants used a solution with 20 PPM fluorescein and the second 10 participants used a solution with 100 PPM fluorescein. After each simulation, participants' hands were photographed under black light to measure the surface area of contamination and the fluorescein was eluted from the hands to measure the mass of fluorescein contamination. A paired t-test was used to compare of the measures of contamination for the left and right hands, but no statistically significant difference was found. As a result, left- and right-hand contamination measurements were then combined to define measures of total dermal exposure (i.e. total mass and total surface area of dermal contamination). A correlation test was run to determine the relationship between mass and surface area of contamination, descriptive statistics were computed to compare total dermal exposure by glove type and by low and high fluorescein. A paired t-test was used to compare the measures of contamination for the short-cuff and long-cuff gloves. Results indicated no statistically significant difference in measures of dermal exposure between long-cuff and short-cuff glove types. Long-cuff gloves did have more variability in dermal exposure compared to short-cuff gloves, which could be due to the extended cuff creating a sense of security and influencing a more vigorous washing behavior compared to the short-cuff simulations. This study demonstrates that fluorescein will penetrate gloves within 10 minutes of dishwashing activity, and that gloves selected based on permeation time do not offer complete protection. This is consistent with previous studies of the effects of repetitive hand movement on glove penetration and permeation. These findings affirm that PPE is an imperfect control method and that dermal exposure to the hands does occur via glove penetration. Glove selection must consider both glove penetration and permeation exposure pathways in order to effectively protect worker health and safety.

description: We demonstrate ultra-low timing jitter optical pulse trains from free- running, 80 MHz repetition rate, mode-locked Yb-fiber lasers. Timing jitter of various mode-locking conditions at close-to-zero intra-cavity dispersion (-0.004 to +0.002 ps2 range at 1040 nm center wavelength) is characterized using a sub-20-attosecond-resolution balanced optical cross-correlation method. The measured lowest rms timing jitter is 175 attoseconds when integrated from 10 kHz to 40 MHz (Nyquist frequency) offset frequency range, which corresponds to the record-low timing jitter from free-running mode-locked fiber lasers so far. We also experimentally found the mode-locking conditions of fiber lasers where both ultra-low timing jitter and relative intensity noise can be achieved.

description: If a tennis ball is held above a basket ball with their centers vertically aligned, and the balls are released to collide with the floor, the tennis ball may rebound at a surprisingly high speed. We show in this article that the simple textbook explanation of this effect is an oversimplification, even for the limit of perfectly elastic particles. Instead, there may occur a rather complex scenario including multiple collisions which may lead to a very different final velocity as compared with the velocity resulting from the oversimplified model.

description: We construct an anomaly-free extension of the left-right symmetric model, where the maximal flavor group is gauged and anomaly cancellation is guaranteed by adding new vectorlike fermion states. We address the question of the lowest allowed flavor symmetry scale consistent with data. Because of the mechanism recently pointed out by Grinstein et al. tree-level flavor changing neutral currents turn out to play a very weak constraining role. The same occurs, in our model, for electroweak precision observables. The main constraint turns out to come from WR-mediated flavor changing neutral current box diagrams, primarily K - Kbar mixing. In the case where discrete parity symmetry is present at the TeV scale, this constraint implies lower bounds on the mass of vectorlike fermions and flavor bosons of 5 and 10 TeV respectively. However, these limits are weakened under the condition that only SU(2)_R x U(1)_{B-L} is restored at the TeV scale, but not parity. For example, assuming the SU(2) gauge couplings in the ratio gR/gL approx 0.7 allows the above limits to go down by half for both vectorlike fermions and flavor bosons. Our model provides a framework for accommodating neutrino masses and, in the parity symmetric case, provides a solution to the strong CP problem. The bound on the lepton flavor gauging scale is somewhat stronger, because of Big Bang Nucleosynthesis constraints. We argue, however, that the applicability of these constraints depends on the mechanism at work for the generation of neutrino masses.

An Evaluation Of Radical Liberal Critics Of Sir Edward Grey's Foreign Policy - 1905-1914

Subjects: Uncategorized

description: This thesis is an examination of the nature and impact of ‘Radical criticism’ influencing the conduct of Anglo-German policy under the Foreign Secretary, Sir Edward Grey, from taking office in December 1905 to the outbreak of war in August 1914. Grey’s foreign policy was influenced by forces that restricted the choices he could make. In the 1960s and 1970s, a limited amount of research on this topic was carried out. Since then, it has received very little attention and can be regarded as almost entirely neglected. There is considerable scope for looking more closely at primary source material, some of which has relatively recently come to light. Limited attention is paid to the policies themselves, as the emphasis will be on what others thought of the way Grey operated, what justification they had for their views, and the impact of these on Grey’s methods and policies.The thesis fills gaps in the historiographical landscape and questions several conclusions that the few published sources have made, which have not fully related Radicals, the issue of influence and Grey’s policies. The thesis re-examines that landscape, given a lapse of almost fifty years since the last significant reference work was published.

description: The decision which hardware platform to use for a certain application is an important problem in computer architecture. This paper reports on a study where a data-mining approach is used for this decision. It relies purely on source-code characteristics, to avoid potentially expensive program executions. One challenge in this context is that one cannot infer how often functions that are part of the application are typically executed. The main insight of this study is twofold: (a) Source code characteristics are sufficient nevertheless. (b) Linking individual functions with the runtime behaviour of the program as a whole yields good predictions. In other words, while individual data objects from the training set may be quite inaccurate, the resulting model is not.
On the role of multicomponent diffusion and electrochemical migration for reactive transport in porous media
Creators: name: Rasouli, Pejman
Publisher: name: University of British Columbia
Year: 2017

description: In multicomponent solutions, electrostatic coupling between charged species leads to a process called “electromigration”. Neglecting electromigration results in a charge imbalance and an incomplete and unrealistic description of mass transfer. Although not commonly considered in reactive transport codes, electromigration can strongly affect mass transport processes and can explain unexpected behaviors such as uphill diffusion or isotope fractionation. Including electrostatic coupling in reactive transport codes enables simulation of problems involving mass transport by advection and diffusion, electromigration and geochemical reactions, such as electrokinetic remediation and the geobattery concept associated with buried ore bodies. There are generally two methods for coupling charge and mass continuities. The first method is based on the null-current approach which assumes negligible electric current transmission. The second method considers explicit coupling of mass and electric fluxes. In this study both methods are investigated and their implications for reactive transport are examined. To this end, MIN3P, a fully coupled 3D reactive transport code, was extended by integrating the Nernst-Planck and Gauss-Ampère equations. The implementation of the Nernst-Planck equations was verified by inter-comparison with other existing reactive transport codes based on a set of benchmark problems. At the same time, these benchmark problems illustrate the effect of electric coupling during multicomponent diffusion and electrochemical migration. By explicit coupling of the Nernst-Planck and Gauss-Ampère equations, MIN3P was further enhanced to simulate electrokinetic remediation and the resulting code was tested for desalination problems. In addition, scenario and sensitivity analysis were used to investigate the potential for spontaneous exsolution of gases in response to gas generation at the electrodes of electrokinetic remediation systems. Finally, a process-based model linking surface-measureable self-potential signals to electrochemical transport and geochemical reactions associated with buried metallic bodies was developed. The enhanced code provides a reactive transport modeling framework for process-based forward modeling of self-potential signals and associated geochemical signatures of buried ore bodies and allows a quantitative investigation of the “geobattery concept”. The code was tested based on published data from a laboratory experiment involving a buried iron bar and used to evaluate the geobattery concept based on an illustrative example of a buried ore body.

description: The thesis studies coalgebras and comodules in higher categories. Rigidification results compare homotopy coherent objects with their strict analogues and we prove that it is not possible to rigidify coalgebras in spectra. However, we also show that comodules in connective modules over the Eilenberg-Mac Lane spectrum over a field can be rigidified if the coalgebra is simply connected and strict. This allows to define the notion of derived cotensor product of comodules

Review of pediatric dentistry oral sedation outcomes and influences
Creators: name: Alkafaji, Zina
Publisher: name: University of British Columbia
Year: 2017

description: Objectives: The UBC Graduate Pediatric Dentistry Program’s oral sedation clinic has evolved since it began in 2011. The study aimed to evaluate the effectiveness and safety of the various sedation regimens used, and to assess how regimens were influenced by the experience and opinions of clinical instructors. Methods: A retrospective chart review of all oral sedation appointments that took place between March 2011 and May 2014 was completed. The outcome variables of interest were effectiveness and safety. Descriptive and comparative statistics were applied to analyze quantitative data. Six UBC Pediatric Dentistry clinical instructors were invited for interviews through a purposive sampling technique to further understand both their views toward sedation regimens and teaching sedation to graduate students. Thematic analysis was applied to code interview transcripts. Results: There were 195 oral sedation appointments during the study period. The three most commonly used regimens were: midazolam and hydroxyzine (MZH) (45%); midazolam (MZ) (24%); and meperidine, chloral hydrate, hydroxyzine, and dimenhydrinate (MCHHD) (17%). With respect to safety, vital signs and level of sedation were examined. Children undergoing MZH sedations were rated to be in “deep” sedation 1.4% of the time, compared to 12.5% in the MCHHD group. MZH sedations were rated “effective/very effective” 90% of the time, compared with 88% for MCHHD sedations. Data for sedation level and effectiveness of the MZ group was limited. Domains that emerged from the interviews were safety, effectiveness, preparation, and preferences; with risk tolerance as the overarching theme. Conclusion: MZH and MCHHD have similar effectiveness however MZH has a better safety profile. Clinicians with higher risk tolerance tended to practice sedation more frequently than those with low risk tolerance. Accordingly, high risk tolerance clinicians felt students should learn sedation more extensively than did those with low risk tolerance. Two main recommendations emerged from the study: (1) complete and inclusive sedation records are critical to fully understanding the effectiveness and safety of sedation regimens; 2) clinicians may desire to have self-awareness regarding their risk tolerances in the context of both practicing and teaching oral sedation in pediatric dentistry.

description: We study a non-perturbative formulation of N=4 super Yang-Mills theory (SYM) on RxS^3 proposed in arXiv:0807.2352. This formulation is based on the large-N reduction, and the theory can be described as a particular large-N limit of the plane wave matrix model (PWMM), which is obtained by dimensionally reducing the original theory over S^3. In this paper, we perform some tests for this proposal. We construct an operator in the PWMM that corresponds to the Wilson loop in SYM in the continuum limit and calculate the vacuum expectation value of the operator for the case of the circular contour. We find that our result indeed agrees with the well-known result first obtained by Erickson, Semenoff and Zarembo. We also compute the beta function at the 1-loop level based on this formulation and see that it is indeed vanishing.

description: Despite its major role in the evolution of the interstellar medium, the formation of high-mass stars (M > 10 Msol) is still poorly understood. Two types of massive star cluster precursors, the so-called Massive Dense Cores (MDCs), have been observed, which differ in their mid-infrared brightness. The origin of this difference is not established and could be the result of evolution, density, geometry differences, or a combination of these. We compare several molecular tracers of physical conditions (hot cores, shocks) observed in a sample of mid-IR weak emitting MDCs with previous results obtained in a sample of exclusively mid-IR bright MDCs. The aim is to understand the differences between these two types of object. We present single-dish observations of HDO, H2O-18, SO2 and CH3OH lines at lambda = 1.3 - 3.5 mm. We study line profiles and estimate abundances of these molecules, and use a partial correlation method to search for trends in the results. The detection rates of thermal emission lines are found to be very similar between mid-IR quiet and bright objects. The abundances of H2O, HDO (1E-13 to 1E-9 in the cold outer envelopes), SO2 and CH3OH differ from source to source but independently of their mid-IR flux. In contrast, the methanol class I maser emission, a tracer of outflow shocks, is found to be strongly anti-correlated with the 12 micron source brightnesses. The enhancement of the methanol maser emission in mid-IR quiet MDCs may indicate a more embedded nature. Since total masses are similar between the two samples, we suggest that the matter distribution is spherical around mid-IR quiet sources but flattened around mid-IR bright ones. In contrast, water emission is associated with objects containing a hot molecular core, irrespective of their mid-IR brightness. These results indicate that the mid-IR brightness of MDCs is an indicator of their evolutionary stage.

Abortion Care and Medicaid Policy In Illinois

Subjects: Uncategorized

description: Illinois House Bill 40 (HB 40) went into effect January 1, 2018, enabling for the first time in decades, Illinois state funds to be used to cover abortion services for Medicaid eligible persons without restriction. In order to understand abortion-providing facilities’ perceptions of Medicaid, HB 40, and the implementation of post-HB 40 Medicaid billing systems, staff representing 83% of abortion-providing facilities in Illinois were interviewed approximately one year after HB 40 went into effect, and their responses were thematically analyzed, with themes generated both deductively from the Consolidated Framework of Implementation Research, and inductively from the data. The main barrier to becoming a Medicaid provider for abortion-providing clinics was the universal perception that Medicaid’s reimbursement rate for abortion services was too low for clinics to be financially sustainable; clinics that chose to apply to become Medicaid providers did so because their mission of enabling access to abortion outweighed their financial concerns. Facilities that sought to become Medicaid providers after the passage of HB 40 described the application process as frustrating and lengthy. The primary facilitators of becoming a Medicaid provider within a year of beginning the application process were a particularly dedicated or experienced individual driving the application, the tangible and social support provided by an ACLU-convened workgroup, and privately donated funds that covered care for Medicaid-eligible patients for clinics in the Medicaid application process. Abortion-providing, Medicaid-accepting facilities also described factors that challenged or facilitated their ability to correctly bill Medicaid after HB 40. Regarding the impact of HB 40, respondents at most facilities perceived little change in patient load or staffing. Nearly every respondent extemporaneously spoke about the positive effect they had seen for their patients’ health and wellbeing. The administrative records of one Illinois facility were analyzed to identify whether covering abortion care affected the demographic characteristics or gestational age at termination for abortion patients from Illinois. Compared to previous years without coverage and patients from states without coverage, there was a shift in age and increased proportion of second trimester abortions with financial coverage.

description: We investigate the dynamics of magnetization in the phase separated (PS) state after introducing the quenched disorder at the Mn-site of a manganite around half doping. The compound, Pr$_{0.5}$Sr$_{0.5}$Mn$_{0.925}$Ga$_{0.075}$O$_{3}$, exhibits PS with the coexistence of ferromagnetic (FM) and antiferromagnetic (AFM) clusters where the size of the FM clusters is substantially reduced due to the disorder introduced by nonmagnetic Ga substitution. At low temperature, the system develops a new magnetic anomaly, which is marked by a peak in the zero field cooled magnetization. Detailed study of linear as well as nonlinear ac susceptibilities coupled with dc magnetization indicates that this peak arises due to the thermal blocking of nanometer size FM clusters demonstrating superparamagnetic behavior. The system, however, exhibits slow magnetic relaxation, aging effect, memory effect in both field cooled and zero field cooled magnetization below the blocking temperature. These imply the presence of collective behavior induced by the interaction between the clusters. Moreover, the magnetic relaxation measured with positive and negative temperature excursions exhibits asymmetric response suggesting that the dynamics in this phase separated system is accounted by the hierarchical model rather than the droplet model which are commonly used to describe the similar collective dynamics in glassy system.

Characterizing the Integrin-mediated Adhesion Profile of Single Cells by AFM-based Force Spectroscopy
Creators: name: Dao, Lu
Publisher: name: Karlsruhe
Year: 2012

description: AFM-based single cell force spectroscopy (SCFS) is applied to study integrin-mediated cell adhesion to ECM. Bifunctional substrates were used for comparative SCFS which enables direct comparison of single cell adhesion to different ECM molecules. Non-genetic and cell cycle-independent adhesion variations were shown to come from cell-to-cell differences in receptor expression. An inverse regulation between collagen receptor integrin alpha2beta1 and laminin receptors was discovered.

Inhomogeneities in dusty universe - a possible alternative to dark energy?
Creators: name: Chatterjee, S.
Publisher: name: arXiv
Year: 2010
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: There have been of late renewed debates on the role of inhomogeneities to explain the observed late acceleration of the universe. We have looked into the problem analytically with the help of the well known spherically symmetric but inhomogeneous Lemaitre-Tolman-Bondi(LTB) model generalised to higher dimensions. It is observed that in contrast to the claim made by Kolb et al the presence of inhomogeneities as well as extra dimensions can not reverse the signature of the deceleration parameter if the matter field obeys the energy conditions. The well known Raychaudhuri equation also points to the same result. Without solving the field equations explicitly it can, however, be shown that although the total deceleration is positive everywhere nevertheless it does not exclude the possibility of having radial acceleration, even in the pure dust universe, if the angular scale factor is decelerating fast enough and vice versa. Moreover it is found that introduction of extra dimensions can not reverse the scenario. To the contrary it actually helps the decelerating process.

Von Publikationsfonds und Open-Access-Konsortien: Zur Finanzierung von Open Access an Hochschulen und Forschungseinrichtungen
Creators: name: Scholze, Frank
Publisher: name: Karlsruhe
Year: 2013

description: Unter dem Goldenen Weg des Open Access wird die Erstveröffentlichung von wissenschaftlichen Beiträgen in einem elektronischen Medium, z. B. einer Zeitschrift, die gemäß einem Open-Access-Geschäftsmodell organisiert ist, verstanden. Open-Access-Publikationen unterliegen den gleichen Maßstäben der Qualitätssicherung wie traditionelle Publikationen. Die Geschäftsmodelle des Goldenen Weges verlagern die Finanzierung: Forschungsorganisationen und Förderer stellen Mittel bereit, um die Publikationen bereits bei der Veröffentlichung im Rahmen sogenannter Publikationsgebühren zu finanzieren. Zunehmend etablieren sich Publikationsfonds an Hochschulen und Forschungseinrichtungen, um diese neuen Geschäftsmodelle nachhaltiger abzusichern, da sie Transparenz und Wettbewerb stärken. Die DFG fördert diese Entwicklung auf breiter Basis. Parallel dazu werden erste Konsortialverträge geschlossen, um günstige Artikelgebühren oder Pauschalverträge mit Verlagen zu erreichen. Dies reicht von Einzeltiteln wie dem New Journal of Physics bis hin zum Gesamtangebot eines Verlages (Copernicus). Die weitreichendste Initiative stellt hier SCOAP3 dar. Geplant ist, die führenden Zeitschriften in der Hochenergiephysik in Open-Access-Zeitschriften im Sinne des Goldenen Weges umzuwandeln. Der Vortrag gibt einen Überblick über den aktuellen Stand an Hochschulen und Forschungseinrichtungen in diesem Bereich und wagt einen Ausblick auf mögliche Entwicklungen.
Effect of isometric training with short or long rest periods on Achilles tendon morphology : an ultrasound tissue characterization study
Creators: name: Alketbi, Thuraya

Year: 2017

description: Achilles tendon (AT) is the strongest tendon in the body. One of the major causes of AT pathology, chronic tendinopathy, is frequently due to excessive loading. Despite the risk of overuse injury, exercise training with appropriate mechanical loading parameters has been found to trigger an adaptation response in the AT. However, the influence of some loading parameters, such as the duration of rest periods between exercise repetitions, remains unknown. Therefore, the aim of this study was to examine the effect of 10s rest insertion during isometric resistance training (Long rest training; LRT) on the morphological properties of human AT, compared with same training intensity and volume but with 3s rest insertion (short rest training; SRT). I hypothesized that ATs exposed to LRT would demonstrate increased tendon collagen organization and tendon cross-sectional area (CSA) compared with baseline, but that SRT would not demonstrate any change in either variable. To test my hypothesis, we recruited healthy adults, and randomly allocated one leg to LRT and the other to SRT. The exercise protocol consisted of 5 sets of 10 isometric calf presses at 90% of maximum voluntary contraction, three times a week over a 12-weeks training period. Tendon collagen organization (proportion of type I echoes) and CSA were measured by ultrasound tissue characterization before and after the 12-weeks period. The primary outcome was the proportion of type I echoes. In contrast to our hypothesis, neither LRT nor SRT induced an improvement in collagen organization or tendon CSA. However, tendons exposed to SRT demonstrated a reduction in the proportion of type I echoes following exercise from 0.66 (95% CI= 0.60 to 0.70) to 0.55 (95% CI=0.49 to 0.60), (p < 0.05), whereas tendons that were exposed to LRT didn’t demonstrate any reduction in the proportion of type I echoes from baseline (0.60, 95% CI= 0.56 to 0.65) to post-intervention (0.62, 95% CI= 0.57 to 0.67), (p = 0.58). Neither type of exercise had a measurable effect on the AT CSA. Further research is needed to examine the biological changes and mechanical effects that influence tendon morphological change associated with different exercise parameters.

description: Obtaining a good momentum reconstruction of a jet is a compromise between taking it large enough to catch the perturbative final-state radiation and small enough to avoid too much contamination from the underlying event and initial-state radiation. In this paper, we compute analytically the optimal jet radius for dijet reconstructions and study its scale dependence. We also compare our results with previous Monte-Carlo studies.

description: The circle compactification of the 6-dim (2,0) superconformal theory of $A_{N-1}$ type leads the 5-dim SU(N) maximally supersymmetric gauge theory. Instanton solitons embody Kaluza-Klein modes and are conjectured to be composed of partonic constituents. We realize such a parton of 1/N instanton topological charge at the intersection of magnetic flux sheets. After a further compactification with nontrivial Wilson line expectation value, instantons or calorons have been shown to be split into fundamental monopoles of fractional instanton charge. In the symmetric phase with trivial Wilson line expectation value, BPS instanton partons emerge more concretely as nonabelian BPS monopoles of minimum charge allowed in Dirac quantization.
