description: We present the first experimental demonstration of the optical Sagnac effect at the single-photon level. Using a high quality guided-wave heralded single- photon source at 1550 nm and a fibre optics setup, we obtain an interference pattern with net visibilities up to (99.2 $\pm$ 0.4%). On the basis of this high visibility and the compactness of the setup, the interest of such a system for fibre optics gyroscope is discussed.

description: We investigate how the addition of quantum resources changes the statistical complexity of quantum circuits by utilizing the framework of quantum resource theories. Measures of statistical complexity that we consider include the Rademacher complexity and the Gaussian complexity, which are well-known measures in computational learning theory that quantify the richness of classes of real-valued functions. We derive bounds for the statistical complexities of quantum circuits that have limited access to certain resources and apply our results to two special cases: (1) stabilizer circuits that are supplemented with a limited number of T gates and (2) instantaneous quantum polynomial-time Clifford circuits that are supplemented with a limited number of CCZ gates. We show that the increase in the statistical complexity of a quantum circuit when an additional quantum channel is added to it is upper bounded by the free robustness of the added channel. Finally, we derive bounds for the generalization error associated with learning from training data arising from quantum circuits.

description: This letter expands the stability criterion for radially stratified, vertically {unstratified} accretion disks incorporating thermal relaxation. We find a linear amplification of epicyclic oscillations in these disks that depends on the effective cooling time, i.e. an overstability. The growth rates of the overstability vanish for both extreme cases, e.g. infinite cooling time and instantaneous cooling, i.e. the adiabatic and fully isothermal cases. However, for thermal relaxation times $τ$ on the order of the orbital frequency, $τΩ\sim 1$, modes grow at a rate proportional to the square of the Brunt-Väisälä frequency. The overstability is based on epicyclic motions, with the thermal relaxation causing gas to heat while radially displaced inwards, and cool while radially displaced outwards. This causes the gas to have a lower density when moving outwards compared to when it moves inwards, so it feels the outwards directed pressure force more strongly on that leg of the journey. We suggest the term ``Convective Overstability" for the phenomenon that has already been numerically studied in the non-linear regime in the context of amplifying vortices in disks, under the name ``Subcritical Baroclinic Instability". The point of the present paper is to make clear that vortex formation in three-dimensional disks is neither subcritical, i.e. does not need a finite perturbation, nor is it baroclinic in the sense of geophysical fluid dynamics, which requires on vertical shear. We find that Convective Overstability is a linear instability that will operate under a wide range of physical conditions for circumstellar disks.

description: Background: The social transmission of obesity has been reported in adolescent social networks. However, the behavioral antecedents to obesity (physical activity [PA], screen time, and diet) are the factors that would actually be transmitted through these networks. To date, little is known about the social influences affecting an individual adolescent’s PA and screen time behaviors. Purpose: To determine the associations between an adolescent’s PA and screen time and his/her nominated friends’ PA and screen time. Methods: Data were obtained from EAT 2010 (Eating and Activity among Teens), a large cross-sectional study (n=2,126) conducted in 20 middle schools and high schools in Minneapolis/St. Paul, Minnesota, USA during the 2009-2010 academic year. Each participant (Ego) nominated up to six friends (Alters) from a school roster and data from those friends was also obtained as part of the school-based data collection procedures. PA and screen time were assessed with previously used and validated questionnaires. Generalized estimating equation models, stratified by gender, were used to assess associations between adolescents’ PA and screen time and their friends’ PA and screen time. Results: Females’ PA was associated with their male and female friends’ PA, including their female best friends (all p<0.05). Males’ PA was associated with their female friends’ PA (p<0.03). Females’ screen time was associated with their male and female friends’ screen time (p<0.03), but not with their best friends. Males’ screen time was only associated with their female friends’ screen time (p=0.04). Conclusions: The associations between individual and friend PA and screen time, especially in females, indicate a need to consider these social relationships when investigating weight-related behaviors in adolescents. Longitudinal data using validated measures of PA and screen time, and analyzed using sophisticated modeling techniques are needed to better understand social influences on adolescent weight-related behaviors and inform future intervention efforts.

description: Introduction: While total joint replacement surgery successfully reduce joint pain and is associated with a low complication rate, patients experience a wide variation in functional improvement. Pre-surgery emotional state correlates with post-surgical functional improvement in total knee replacement patients. We tested this concept against a national cohort of total hip replacement (THR) patients.

Materials & methods: Patients undergoing primary THR from 7/1/11 through 12/6/13 with postoperative outcomes at 6 months were identified from FORCE-TJR, a US national research consortium. We obtained data on patient demographics, underlying type of arthritis, body mass index (BMI), Charlson Comorbidity Index, arthritic pain in contralateral hip and bilateral knees, back pain, Hip Disability and Osteoarthritis Outcome Score (HOOS), global function based on the Short Form 36 (SF-36) Physical Component Score (PCS) and emotional health using the SF-36 Mental Component Score (MCS). We performed descriptive statistics and multivariable linear regression models to identify factors associated with 6-month postoperative PCS global function scores.

Results: The 1,426 THR patients identified were 60.7% female, 95.0% white, mean age 65.3 years, mean BMI of 29.0. Mean preoperative surgical joint pain, stiffness and function was 50.1 (± 19.2), 38.7 (± 21.9), 46.4 (±19.2) respectively. MCS was 51.56 (± 12.2) and PCS 31.6 (± 8.9). Pre-operative and post-operative functioning differed based on emotional health (MCS ≥50). In multivariable models, lower MCS levels were associated with worse PCS at 6 months (coefficient of 0.18. 95% CI 0.14-0.22) after controlling for demographics, medical comorbidity, baseline PCS and burden of musculoskeletal disease.

Conclusion: Poorer emotional health is associated with poorer global function following surgery and a key factor in the recovery and rehabilitation following THR. Better emotional health screening for THR surgical candidates, and interventions to provide additional emotional support to those who need it, are necessary to ensure optimal functional gain.

description: Localized defects, unavoidable in real solids, may be simulated in (generically defect-free) cold-atom systems, e.g., via modifications of the optical lattice. We study the Hubbard model on a square lattice with single impurities, pairs of nearby impurities, or lines of impurities using numerically exact determinantal quantum Monte Carlo simulations. In all cases, correlations on the "impurity" sites are enhanced either by larger on-site interactions or by a reduced coupling to the environment. We find highly nontrivial magnetic correlations, which persist at elevated temperatures and should be accessible in cold-atom systems with current experimental techniques. With improved cooling techniques, these features could be followed towards generic quantum antiferromagnetism in the homogeneous limit. More generally, tunable crossing points between different correlation functions could be used, in a quantum steelyard balance setup, as robust thermometers.

Electronic health records in social work practice
Creators: name: Matthews, Elizabeth B.
Publisher: name: No Publisher Supplied
Year: 2018

description: The use of electronic health records (EHRs) is becoming normative in behavioral health treatment. Despite this, little is known about how to use these systems in a way that supports best practices, including the provision of person-centered care (PCC). PCC refers to a clinical approach that emphasizes individualized, collaborative care and a strong working alliance (WA) between clients and providers. Collaborative documentation (CD), the process of completing progress notes jointly with clients, has been promoted as a model of in-session computer use that can support this practice, but has been controversial among behavioral health providers. Advancement of CD has been hindered by the lack of empirical studies examining its effectiveness. This quantitative study examines how behavioral health providers use EHRs within a therapeutic context, and tests the impact CD has on PCC.           This exploratory study drew from a sample of 53 therapy sessions where EHRs were used. Data sources included a video recording of each session, and post-visit surveys completed by both clients and providers. Video data was coded for computing frequency, and the use of CD with clients. Surveys measured client and provider ratings of person-centered care and collaborative documentation. Univariate statistics describe the extent of computer use during sessions. Paired sample t-tests explored differences in client and provider perceptions of PCC and CD. Finally, the association between the amount of computer use, CD and PCC was tested using OLS regression, adjusting for nesting with a random effect at the provider level. The first model examined the direct effects of CD on PCC, and a second model explored the moderating effects of CD on the relationship between total computing and PCC.              Results indicate that behavioral health providers spend about 33% of visit time using the computer, but clients and providers view the impact of these behaviors on PCC differently. Among providers, total computing had a direct, negative association with working alliance (WA), an essential component of PCC. Conversely, clients generally had more favorable attitudes towards the quality of their WA with their providers and the ways in which they used computers in sessions. Furthermore, among clients, CD predicted higher ratings of PCC and WA, regardless of how often computers were used.             These findings suggest that, while providers felt pessimistically about the impact of EHRs on PCC, clients did not share this experience, particularly when CD was deployed. To this end, results indicate that requisite skills surrounding collaborative use of technology are critical to harnessing the benefits of this technology. This underscores the need to continue developing and disseminating effective strategies for EHR use.

description: In this paper we introduce a new hierarchical model for the simultaneous detection of brain activation and estimation of the shape of the hemodynamic response in multi-subject fMRI studies. The proposed approach circumvents a major stumbling block in standard multi-subject fMRI data analysis, in that it both allows the shape of the hemodynamic response function to vary across region and subjects, while still providing a straightforward way to estimate population-level activation. An efficient estimation algorithm is presented, as is an inferential framework that not only allows for tests of activation, but also for tests for deviations from some canonical shape. The model is validated through simulations and application to a multi-subject fMRI study of thermal pain.

description: This poster will describe a novel polymer pro-drug platform designed for conjugation and delivery of chemotherapeutics. Specifically, polymer pro-drugs were prepared from functional polymer zwitterions and doxorubicin (DOX), and evaluated in vivo to assess toxicological, pharmacokinetic and therapeutic properties. The biocompatible polymer scaffold (PolyMPC) consists of zwitterionic phosphorylcholine pendent groups, which mimic the natural hydrophilic moieties of phospholipids in cell membranes, and hydrazone linkages that allow for pH-triggered release of DOX. PolyMPC-DOX pro-drugs were isolated as dry solids using a facile strategy that allows for precise control of molecular weight and DOX incorporation. In vivo toxicity of PolyMPC and PolyMPC-DOX was assessed in a murine model. The maximum tolerated dose of the pro-drug was five times greater than that of free DOX, while PolyMPC alone exhibited no toxicity even at a dose of 800 mg/kg. A pharmacokinetic study in tumor-bearing mice demonstrated a significant increase in circulation half-life of conjugated DOX (t1/2=2 hours) compared to free DOX (t1/2=15 minutes), with conjugated DOX detectable in blood serum for longer than 24 hours. This pronounced enhancement in circulation time was attributed to the macromolecular scaffold, which precludes rapid renal clearance compared to native DOX. Examination of mice given PolyMPC-DOX five days after injection in the PK study showed a three-fold increase of drug accumulated in tumor tissue compared to that of mice treated with free DOX and drug accumulation in off-target organs was reduced for mice given DOX conjugate. The therapeutic efficacy of the PolyMPC-DOX conjugates was then assessed in an orthotopic murine breast cancer model. The treatment group given PolyMPC-DOX exhibited a two-fold increase in overall survival and a significant reduction in average tumor volume compared to the free DOX and saline control groups. A study evaluating the therapeutic efficacy of PolyMPC-DOX in a human ovarian xenograft tumor model is ongoing.

description: We generate silicon vacancy related defects in high-quality epitaxial silicon carbide layers by means of electron irradiation. By controlling the irradiation fluence, the defect concentration is varied over several orders of magnitude. We establish the excitation profile for optical pumping of these defects and evaluate the optimum excitation wavelength of 770 nm. We also measure the photoluminescence dynamics at room temperature and find a monoexponential decay with a characteristic lifetime of 6.1 ns. The integrated photoluminescence intensity depends linear on the excitation power density up to 20 kW/cm$^2$, indicating a relatively small absorption cross section of these defects.

description: Current experimental data on the 125 GeV Higgs boson still allow room for large CP violation. The observables usually considered in this context are triple product asymmetries, which require an input of four visible particles after imposing momentum conservation. We point out a new class of CP violating observables in Higgs physics which require only three reconstructed momenta. They may arise if the process involves an interference of amplitudes with different intermediate particles, which provide distinct strong phases in the form of the Breit-Wigner widths, in addition to possible weak phases that arise from CP violating couplings of the Higgs in the Lagrangian. As an example, we propose a forward-backward asymmetry of the charged lepton in the three-body Higgs decay, $h\to \ell^-\ell^+ γ$, as a probe for CP-violating Higgs couplings to $Zγ$ and $γγ$ pairs. Other processes exhibiting this type of CP-violation are also discussed.

Characterization of Water Movement Into and Through Soils During and Immediately After Rainstorms

Year: 1972

description: Abstract:
The movement of water into and through soils in the unsaturated state is basic to many water resources problems including rainfall-runoff models, ground water recharge, irrigation, drainage, evapotranspiration and the movement of pollutants in soils. This study was conducted in an effort to determine if the flow equation based on Darcy's Law and the continuity equation could be used to describe watershed infiltration and thus be incorporated into hydrologic models.
The results of the study indicate that even on apparently uniform soils there is a great deal of variability in soil water properties. Handling this variability plus the difficulty of solving the flow equation led to the conclusion that a simpler approach to modelling watershed infiltration is needed.
A simple infiltration model was developed and included in a rainfall-runoff model. Tests with the model indicate that it produces satisfactory estimates of monthly runoff from small, rural watersheds.
Funding information: The project was supported in part by funds provided by the United States Department of Interior to the University of Kentucky Water Resources Institute as authorized by the Water Resources Act of 1964, Public Law 88-379, as office of Water Resources Research Project No. A-025-KY.

description: Introduction: The utility of engineered nanomaterials’ is growing, particularly the titanium dioxide (TiO2) polymorphs. TiO2 is very useful for brightening paints, and coloring foods. Nano-sized TiO2 is also useful for sunscreens, cosmetics, and can be utilized as a photocatalyst. However, the nanometer size and the large specific surface area of the TiO2 materials are physicochemical characteristics which may contribute to human red blood cell (RBC) damage. Using RBCs as a cellular model, we have evaluated the effects of TiO2 nanoparticle exposure to RBCs by quantifying oxidized glutathione, oxidized membrane vitamin E, hemolysis, hemoglobin adsorption, and cellular aggregation. Results: Red blood cells are rich in the antioxidant glutathione (GSH). HPLC testing revealed that some TiO2 materials have the ability to cause oxidation of GSH to the oxidized form, glutathione disulfide (GSSG). Due to surface area characteristics, some TiO2 materials have the ability to adsorb protein (visualized as hemoglobin) to their surface. Additionally, some TiO2 materials microscopically form red blood cell aggregates, significantly changing the red cell morphology. The aggregation data was quantified using a hemacytometer. Red blood cell membrane vitamin E was also measured by HPLC, and after exposure to these TiO2 polymorphs, some materials caused vitamin E membrane oxidation. Some TiO2 materials have the ability, through multiple different mechanisms, to cause hemolysis of the red blood cell. Conclusions: Our results indicated that some of the TiO2 polymorphs assayed contributed to red blood cell hemolysis via different mechanisms, whereas some polymorphs did not cause cellular damage. These data indicated that red blood cells can ultimately be hemolyzed by biological oxidative damage (BOD), intracellular oxidation of GSH to GSSG, oxidation of vitamin E in the RBC membrane, material adsorption to the RBC membrane, physical contact, or by a combination of these mechanisms.

description: We perform a dynamical calculation of the $ΔΔ$ dibaryon candidates with $IJ^{P}=03^{+}$ and $IJ^{P}=30^{+}$ in the framework of two constituent quark models: the quark delocalization color screening model and the chiral quark model. Our results show that the dibaryon resonances with $IJ^{P}=03^{+}$ and $IJ^{P}=30^{+}$ can be formed in both models. The mass and width of $IJ^{P}=03^{+}$ state are smaller than that of $IJ^{P}=30^{+}$ state due to the one-gluon-exchange interaction between quarks. The resonance mass and decay width of $IJ^{P}=03^{+}$ state in both models agree with that of the recent observed resonance in the reaction $pn \rightarrow dπ^{0}π^{0}$. The $IJ^{P}=30^{+}$ $ΔΔ$ is another dibaryon candidate with smaller binding energy and larger width. The hidden-color channel coupling is added to the chiral quark model, and we find it can lower the mass of the dibaryons by 10-20 MeV.

description: Studies have shown that low-income and minority Americans have a poor diet quality, which increases obesity and chronic disease risk. According to the Massachusetts Department of Public Health, Springfield is among the top five poorest cities in the state. To promote healthy eating behaviors among Springfield residents, Mason Square Health Task Force, a Live Well Springfield (LWS) partner, created a 6-session nutrition curriculum, entitled The MENU Program. The goal is to increase overall health awareness and healthy eating behaviors among residents in communities that are being targeted by the LWS initiative. The program was piloted with a group of female Mason Square residents, aged 60-85 years (n=12), at the Dunbar YMCA in Springfield, MA. Pre-and post-surveys were administered at sessions #1 and #6 to assess nutrition-related knowledge, attitudes and behaviors. Brief process evaluations were administered at the end of each 60 to 90 minute session to identify program strengths and limitations. Preliminary analysis reveals that participants increased their vegetable intake by 34% and consumption of fresh/frozen fruits and vegetables (vs. canned) increased by 9% and 18%, respectively. Those who reported “always” or “usually” reading nutrition labels increased from 54% to 72%, and those who reported “always” or “usually” shopping at a farmer’s market increased from 18% to 36%. Process evaluations showed positive responses to most of the material presented, particularly information regarding My Plate, portion control, and nutrition label reading. Further data analysis will inform revision of The MENU Program for use with larger, more diverse groups of Springfield residents.

description: We describe ideal incompressible hydrodynamics on the hyperbolic plane which is an infinite surface of constant negative curvature. We derive equations of motion, general symmetries and conservation laws, and then consider turbulence with the energy density linearly increasing with time due to action of small-scale forcing. In a flat space, such energy growth is due to an inverse cascade, which builds a constant part of the velocity autocorrelation function proportional to time and expanding in scales, while the moments of the velocity difference saturate during a time depending on the distance. For the curved space, we analyze the long-time long-distance scaling limit, that lives in a degenerate conical geometry, and find that the energy-containing mode linearly growing with time is not constant in space. The shape of the velocity correlation function indicates that the energy builds up in vortical rings of arbitrary diameter but of width comparable to the curvature radius of the hyperbolic plane. The energy current across scales does not increase linearly with the scale, as in a flat space, but reaches a maximum around the curvature radius. That means that the energy flux through scales decreases at larger scales so that the energy is transferred in a non-cascade way, that is the inverse cascade spills over to all larger scales where the energy pumped into the system is cumulated in the rings. The time-saturated part of the spectral density of velocity fluctuations contains a finite energy per unit area, unlike in the flat space where the time-saturated spectrum behaves as k^{-5/3}.

For such range of masses, the Majorana neutrino will go on its mass shell and the two charged leptons will appear at displaced vertices or, if the lifetime is long enough, most secondary vertices will fall outside the detector. We study the consequences of this effect on the experimental searches and limits that can be extracted.

description: This research focuses on the 2D and 3D geospatial analysis of the Ryukyu Trench, a deep-sea trench located in the western Pacific Ocean between Japan and Taiwan. The aim of the research is to visualize regional differences in the topography of the southern (S) and northern (N) parts of the trench. Technically, the methodology is based on using the Generic Mapping Tools (GMT) scripting toolset, for modelling the General Bathymetric Chart of the Oceans (GEBCO), and Earth Topography and Bathymetry dataset (ETOPO1) raster grids. The results demonstrated topographic differences in the two segments. The most frequent depths lie between -5,000 and -6,000 m. The N part has steeper gradient slopes and deeper bathymetry. Of the depth differences >-6,000 m, S has nine values with depths >-6,800 m while N shows 123 records (max -7,460 m). The submarine terraces of S have gentler slopes compared with the N segment. The technical approach presents GMT-based 2D and 3D cartographic modelling aimed at visualizing regional variations of the seafloor topography.

description: Background/Aims: To understand the value of our substantial investment in cardiovascular disease (CVD) care, it is important to understand the associations of CVD therapies and spending. The aim of this study was to assess the effect of increased utilization of CVD medications on spending among different CVD risk subgroups.

Methods: We used 1999-2009 Medicare Current Beneficiary Survey data to identify 26,903 non-institutionalized, fee-for-Service 65 years or older users of angiotensin converting enzyme inhibitor (ACE), angiotensin receptor blocker (ARBs), other antihypertensives, and statins(61,741person-years). For each drug, we used generalized linear models to estimate the effect of additional prescription fills on spending (i.e. overall, Medicare, out-of-pocket); stratified according to presence of CVD and, in those without CVD, level of CVD risk (high versus low).

Results: In the high CVD risk subgroup, each additional prescription fill of ACE, ARB, or statindecreased overall spending (marginal effects: -$274 (CI=-405, -143), -$139 (CI=-300, 22), and -$93 (CI=-250, 64) respectively) and Medicare spending (marginal effects: -$273 (CI=-386, -160), -$156 (CI=-314, 3), and -$160 (CI=-306, -14) respectively). Similar patterns were found in the subgroup with CVD (marginal effects of ACE, ARB, and statins on overall spending: -$184 (CI=-362, -6), -$184 (CI=-377, 8), and -$117 (CI=-235, 2); and on Medicare spending (-$232 (CI=-362, -103), -$186 (CI=-363, -9), and -$229 (CI=-328, -130)). The increased use of these drugs has the opposite effect in the low CVD risk subgroup generally. In contrast, in all 3 subgroups, each additional prescription fill of these drugs generally increased out-of-pocket spending by up to $55.

Conclusions: We observed overall cost-savings associated with increased use of CVD medications among both patients with pre-existing CVD and those at high CVD risk. Eliminating or reducing copays for these drugs (i.e. value based insurance design) for such patients may improve their overall health and save money.

description: Purpose: Mutations in the CEP290 gene are a frequent cause of childhood blindness disorder, Leber congenital amaurosis (LCA). Not much is known about the mode of action of CEP290 in the retina. We previously showed that CEP290 interacts with RKIP and that RKIP protein is abnormally accumulated in rd16 (retinal degeneration 16) mouse, a model of Cep290- associated retinal degeneration. The purpose of this study is to evaluate the role of RKIP accumulation in mediating photoreceptor degeneration in the rd16 mouse.

Methods: rd16/rd16:Rkip ko/Rkip ko double homozygous knock out mice were generated by breeding rd16 and Rkip ko mice (both on C57BL6/J background). Photoreceptor structure and function were evaluated by Histology, Transmission electron microscopy (TEM), Immunofluorescence microscopy and Electroretinography (ERG).

Results: We detected improved photoreceptor structure in the double homozygous mutant mice compared to rd16 at postnatal day 18 (P18). In addition, Rhodopsin and M-opsin staining in Rd16 Rkip-/- mouse showed increased outer segment localization in the double mutant mice. Finally, ERG analysis showed 40% scotopic response recovery in Rd16 Rkip-/- from Rd16 mouse.

Conclusions: We propose that accumulation of RKIP due to mutation in CEP290, although not the only pathway is a critical step in the pathogenesis of associated severe retinal degeneration. Altering RKIP levels may potentially be used in combination with other modalities as an approach for treating such disorders.

description: We report on magnetization, specific heat and resistivity experiments on single crystals of the novel heavy Fermion compound Ce$_3$PdIn$_{11}$. At ambient pressure the compound exhibits two successive transitions at T$_{1}$ = 1.63 K and T$_{\mathrm {N}}$ = 1.49 K into incommensurate and commensurate local moment antiferromagnetic states, respectively, before becoming superconducting below T$_{\mathrm {c}}$ = 0.42 K. The large values of dB$_{\mathrm {c2}}$/dT and B$_{\mathrm {c2}}$ = 2.8 T imply that heavy quasiparticles form the Cooper pairs. Thus, Ce$_{3}$PdIn$_{11}$ is the first ambient pressure heavy Fermion superconductor where 4f electrons are simultaneously responsible for magnetic order and superconductivity.

description: Only ~50% of patients with diffuse large B-cell lymphoma (DLBCL), the most common and aggressive subtype of non-Hodgkin’s lymphoma, enter long-term remission after standard chemotherapy, and patients who do not respond to treatment have few options. Therefore, there is a critical need for effective and targeted therapeutics for DLBCL. Recent studies highlight the incidence of increased c-MYC protein in DLBCL and the correlation between high levels of c-MYC and poor survival prognosis of DLBCL patients, suggesting that c-MYC is a compelling therapeutic target for DLBCL therapy. The small molecule JQ1 suppresses c-MYC expression through inhibition of the BET family of bromodomain proteins. We show that JQ1 efficiently inhibited cell proliferation of human DLBCL cells regardless of their molecular subtypes, suggesting a broad effect of JQ1 in DLBCL. After JQ1 treatment, initial G1 arrest in DLBCL cells was followed by either apoptosis or senescence. In DLBCL cells treated with JQ1, we found that c-MYC expression was suppressed in the context of the natural, chromosomally-translocated or an amplified gene locus. Furthermore, JQ1 treatment significantly suppressed growth of DLBCL cells engrafted subcutaneously and improved survival of mice engrafted with DLBCL cells intraperitoneally. These results demonstrate that inhibition of the BET family of bromodomain proteins, and consequently c-MYC, has the potential clinical utility in DLBCL treatment.

description: BACKGROUND: Despite encouraging declines in short-term mortality in patients hospitalized with acute myocardial infarction (AMI), repeat hospitalizations among those discharged from the hospital after AMI remain a major clinical and public health concern. Few studies, however, have described the relatively contemporary magnitude, factors associated with, as well as decade long trends in repeat hospitalizations for cardiovascular disease (CVD) and other causes in patients discharged from the hospital after AMI.

METHODS: We reviewed the medical records of 6,018 residents of the Worcester (MA) metropolitan area who were hospitalized for AMI in 6 biennial periods between 1999 and 2009. Re-hospitalizations for any reason were recorded over a 2-year follow-up period.

RESULTS: The average age of our study population was 70.3 years and 56.4% were men. Overall, 48.1% of our sample had at least 1 re-hospitalization for any cause after hospital discharge for AMI over the 2-year follow-up period. Of these, 45.7% of the repeat hospitalizations were attributed to CVD, 42.1% were non-CVD related, and 10.6% were due to AMI. The frequency of re-hospitalizations due to any cause declined slightly between 1999 and 2009 from 47.1% to 45.4% , marginally increased in those with CVD (from 46.3% to 47.9%) or non-CVD causes (from 36.9% to 38.3%), while the proportion of patients re-hospitalized for AMI decreased from 16.9% in 1999 to 13.9% in 2009. Older patients, those who developed an NSTEMI, who had a history of selected CVD and Non-CVD comorbidities, and who had received a percutaneous coronary intervention were more likely to have been re-hospitalized during the 2-year follow-up period, as compared with those who were not re-hospitalized (Table 1).

CONCLUSIONS: The present results provide insights into the magnitude and causes of re-hospitalizations among patients discharged from the hospital after AMI .Risk of re-hospitalization after AMI was particularly high among older patients presenting with selected comorbidities.

description: Purpose: Far cortical locking has been proposed for reducing stiffness and promoting greater dynamic stability in locked plating constructs. Prior studies have shown reduced stiffness with axial loading of these constructs, leading to a theoretical increase in inter-fragmentary motion and secondary bone healing. The purpose of this study was to examine strain across a fracture gap using far cortical locking constructs in a biomechanical model of distal femoral fractures.

Methods: Fourth generation sawbones were cut transversely along the distal diaphysis and plated with distal femoral buttress plates and cortical locking screws. Far cortical locking (FCL) specimens were predrilled in the lateral cortex and control specimens were plated with a standard locked plating construct. The constructs were loaded sequentially with 100, 200, and 400 lbs of force on a mechanical test frame. Displacement across the fracture gap measured in pixels using an optical system.

Results: Strain across the fracture gap increased with progressive loading from zero to 400 lbs in both groups. Strain also decreased in a linear fashion from medial to lateral across the fracture gap in both constructs (Figure 1). Standard locking constructs exhibited an average 28% greater strain than the far cortical locking constructs at all loading forces. Control specimens exhibited greater lateral displacement of the distal segment relative to the plate (Figure 2), consistent with higher shear forces compared to FCL specimens.

Conclusions: In all specimens, there was considerable strain seen with loading that increased in characteristic fashion from lateral to medial. Overall, FCL constructs exhibited both lower strain, and importantly, lower shear, than measured in controls. This biomechanical model suggests that FCL changes loading across the femoral diaphysis in complex ways, and that assumptions about strain approaching zero on the lateral side of the distal femur with conventional locking or FCL may be incorrect.

description: We investigate collision of a point particle and an infinitely thin planar domain wall interacting gravitationally within the linearized gravity in Minkowski space-time of arbitrary dimension. In this setting we are able to describe analytically the perforation of the wall by an impinging particle, showing that it is accompanied by excitation of the spherical shock branon wave propagating outwards with the speed of light. Formally, the shock wave is a free solution of the branon wave equation which has to be added to ensure the validity of the retarded solution at the perforation point. Physically, the domain wall gets excited due to the shake caused by an instantaneous change of sign of the repulsive gravitational force. This effect is shown to hold, in particular, in four space-time dimensions, being applicable to the problem of cosmological domain walls.
