description: The study of exclusive processes in the future electron-ion ($eA$) colliders will be an important tool to investigate the QCD dynamics at high energies as they are in general driven by the gluon content of the target which is strongly subject to parton saturation effects. In this paper we compute the coherent and incoherent cross sections for the deeply virtual Compton scattering (DVCS) process relying on the color dipole approach and considering different models for the dipole - proton scattering amplitude. The dependencies of the cross sections with the energy, photon virtuality, nuclear mass number and squared momentum transfer are analysed in detail. We demonstrate that the ratio between the incoherent and coherent cross sections decreases at smaller values of $Q^2$ and increases at smaller values of $A$. We show that the coherent cross section dominates at small $t$ and exhibits the typical diffractive pattern, with the number of dips in the range $|t| \le 0.3$ GeV$^2$ increasing with the mass atomic number. Our results indicate that the position of the dips are independent of the model used to treat the dipole - proton interaction as well as of the center-of-mass energy.

description: BACKGROUND: Pulmonary hypertension (PHT) is common in sickle cell disease (SCD). The purpose of this study was to determine whether markers of coagulation activation and inflammation are associated with PHT in SCD. DESIGN AND METHODS: This cross-sectional study was performed using a cohort of patients followed at an adult Sickle Cell Clinic. Pulmonary artery systolic pressure was determined by Doppler echocardiography, and the diagnosis of PHT was defined using age, sex and body mass index-adjusted reference ranges. Clinical laboratory examinations, including hematologic studies and biochemical tests, as well as various measures of coagulation activation, endothelial activation and inflammation, were conducted on SCD subjects and on healthy, race-matched control subjects without SCD. RESULTS: Patients with SCD (n=76) had higher plasma levels of markers of coagulation (thrombin-antithrombin complex, prothrombin fragment F1+2, D-dimer) and endothelial (soluble vascular endothelial cell adhesion molecule, sVCAM) activation compared with control subjects (n=6). SCD patients with PHT (n=26) had significantly higher levels of sVCAM compared with those patients without PHT (n=50). Although PHT patients showed increased plasma measures of coagulation activation, the differences were not statistically significant when compared to those of patients without PHT. HbSS patients with PHT also had a trend towards higher levels of other inflammatory cytokines (interleukins 6, 8 and 10) than HbSS patients without PHT. There was a modest negative correlation between hemoglobin and plasma measures of coagulation and endothelial activation, and modest positive correlations between markers of hemolysis and plasma measures of coagulation and endothelial activation. CONCLUSIONS: SCD patients with PHT have higher levels of markers of endothelial activation and other inflammatory markers than patients without PHT. A trend towards an increased level of markers of coagulation activation was observed in SCD patients with PHT compared with that in patients without PHT. Markers of hemolysis are associated with coagulation activation and endothelial dysfunction in SCD patients. Clinical trials of anticoagulants and anti-inflammatory agents are warranted in SCD patients with PHT.

description: The frequently reported observation that nomadic populations have lower fertility than their settled counterparts is often attributed to what are perceived as harsh, stressful conditions under which the nomads live. But the consequences of the hypothesized stresses for the reproductive biology or demography of these populations have been documented only a little. Traditionally, the Turkana of northwest Kenya are nomadic herders, but increasing numbers have settled on agricultural development schemes. We used an array of hormonal assays along with anthropometric indexes of nutritional status and interviews covering reproductive history, recent menstruation, diet, and health to compare reproductive function in nomadic and settled Turkana women. First morning urine samples were collected for three consecutive days during a series of surveys. Human choriogonadotropin (hCG; a marker for pregnancy), luteinizing hormone (LH; an indicator of ovulation), and pregnanediol glucuronide (PdG; an indicator of postovulatory luteal function) were assessed in the field with commercially available dipstick enzyme immunoassays. These assays along with the interview data allowed us to determine the reproductive status (e.g., pregnant or cycling, and if cycling, which phase of the ovarian cycle) of 166 nomadic and 194 settled Turkana women. The cross-sectional classifications allowed inferences of conception rates and normality of ovarian function. Follow-up surveys provided rates of pregnancy loss. Compared with the settled women, the nomadic women exhibited lower pregnancy rates and cycling nomadic women were less likely to show evidence of ovulation or luteal function. These results suggest that reproductive function of the nomadic women is diminished relative to the settled women. However, the settled women experienced a much higher rate of pregnancy loss, which may mean that their effective fecundability is in fact lower than that of the nomadic women. This study is the first to apply such a wide range of hormonal assays in the field. It demonstrates that field-based assays are feasible and robust and can play an important role in epidemiological and biodemographic studies, even in remote locations under conditions that would ordinarily be considered incompatible with on-site laboratory analysis.

description: In this paper we show that every nonsingular conservative ergodic n-to-one endomorphism of a Lebesgue probability space has a factor which is isomorphic to the Cartesian product of an automorphism with a one-sided shift. The measure on the product space is always a nonsingular joining of the factor measures on each factor, but is not in general a product measure. It decomposes over the automorphic factor into a family of measures each of which is trivial on the tail σ-algebra of the shift. We give necessary and sufficient conditions under which the measure is a product measure and study the marginal measures in the general case. Necessary and sufficient conditions are given under which the marginal measure on the shift space is exact. We show that the theorem cannot be strengthened by constructing a finite measure-preserving ergodic two-to-one endomorphism whose product structure cannot be given product measure.

description: We study voting rules with respect to how they allow or limit a majority from dominating minorities: whether a voting rule makes a majority powerful, and whether minorities can veto the candidates they do not prefer. For a given voting rule, the minimal share of voters that guarantees a victory to one of their most preferred candidates is the measure of majority power, and the minimal share of voters that allows them to veto each of their least preferred candidates is the measure of veto power. We find tight bounds on these minimal shares for voting rules that are popular in the literature and in real elections. We order these rules according to majority power and veto power. The instant-runoff voting has both the highest majority power and the highest veto power and the plurality rule has the lowest. In general, the higher the majority power of a voting rule is, the higher its veto power. The three exceptions are: voting with proportional veto power, Black's rule, and Borda rule, which have a relatively low level of majority power and a high level of veto power and thus provide minority protection. Our results can shed light on how voting rules provide different incentives for voter participation and candidate nomination.

description: We explore a method developed in statistical physics which has been argued to have exponentially small finite-volume effects, in order to determine the critical temperature Tc of pure SU(3) gauge theory close to the continuum limit. The method allows us to estimate the critical coupling betac of the Wilson action for temporal extents up to Nt ~ 20 with < 0.1% uncertainties. Making use of the scale setting parameters r0 and sqrt{t0} in the same range of beta-values, these results lead to the independent continuum extrapolations Tc r0 = 0.7457(45) and Tc sqrt{t0} = 0.2489(14), with the latter originating from a more convincing fit. Inserting a conversion of r0 from literature (unfortunately with much larger errors) yields Tc / LambdaMSbar = 1.24(10).

description: We study ex-post fairness in the object allocation problem where objects are valuable and commonly owned. A matching is fair from individual perspective if it has only inevitable envy towards agents who received most preferred objects -- minimal envy matching. A matching is fair from social perspective if it is supported by majority against any other matching -- popular matching. Surprisingly, the two perspectives give the same outcome: when a popular matching exists it is equivalent to a minimal envy matching. We show the equivalence between global and local popularity: a matching is popular if and only if there does not exist a group of size up to 3 agents that decides to exchange their objects by majority, keeping the remaining matching fixed. We algorithmically show that an arbitrary matching is path-connected to a popular matching where along the path groups of up to 3 agents exchange their objects by majority. A market where random groups exchange objects by majority converges to a popular matching given such matching exists. When popular matching might not exist we define most popular matching as a matching that is popular among the largest subset of agents. We show that each minimal envy matching is a most popular matching and propose a polynomial-time algorithm to find them.
IDENTIFICATION OF A SOURCE TERM AND A COEFFICIENT IN A PARABOLIC DEGENERATE PROBLEM

description: The globally in time existence and uniqueness of solutions to inverse problems is one of the most difficult questions to be answered. Even though the direct problems are well-posed in the sense of Hadamard (i.e. existence, uniqueness and stability results hold true), the inverse ones generally are not. The situation gets more complicated if the equation contains more than one unknown coefficient, and even more if the unknown functions depend on different variables. We consider the following identification abstract problem in a general Banach space $X$: find a function $u:[0,T] \to X,$ a coefficient $a_1:[0,T] \to \mathbb R$ and a vector $z \in X$ such that the initial-value problem \begin{align} &\frac{1}{a_0(t)}\ u'(t)-Au(t)-a_1(t)u(t)\!=\!f(t)z+g(t), \qq u(0)=u_0 \label{zi2} \end{align} is fulfilled, where $a_0(t)>0$ and $a_0(t)=0$ only in some negligible set, while $A:D(A)\subset X \to X$ is a closed linear operator, $f$ is scalar functions and $g$ is a $X$-valued source term. The occurrence of two unknowns require to introduce two additional conditions. We choose the first as nonlocal one in the integral form $\imi \!\!\varphi(t)u(t)d\mu(t)\!=\!h,$ where $\mu$ is a Borel measure on the interval $[0,T].$ The latter is of the following form: $\Phi[u(t)]=k(t), \: t\!\in\! [0,T],$ where $\Phi$ is a prescribed linear continuous functional. Here the functions $h$, $k, \varphi$ are scalar. So, we investigate the problem (\ref{zi2}) along with these additional conditions. We study explicitly the case of the \textit{Dirac measure} concentrated at $t=T_1, 0

But Its scheme has to send multiple shares to each trustee. In this paper, we proposed two new secret sharing schemes realizing general access structures by only assigning one share to each trustee. Our proposed second scheme is a perfect secret sharing scheme. Furthermore, our schemes can realize any access structures.

This generalizes the authors' recent result obtained for a Euclidean sphere of arbitrary dimension. Furthermore, similar heat kernel bounds are shown in the context of classical Jacobi expansions, on a ball and on a simplex. These results are more precise than the qualitatively sharp Gaussian estimates proved recently by several authors.

description: We consider a family of rotationally symmetric, asymptotically Euclidean manifolds with two trapped sets, one of which is unstable and one of which is semistable. We prove a sharp local smoothing estimate for the linear Schrödinger equation with a loss that depends on how flat the manifold is near each of the trapped sets. The result interpolates amongst the members of the family of similar estimates in [CW13]. As a consequence of the techniques used in our proof, we also show a sharp high-energy resolvent estimate with a polynomial loss that depends on how flat the manifold is near each of the trapped sets.

description: The nonlinear dynamics of waves at the sea surface is believed to be ruled by the Weak Turbulence framework. In order to investigate the nonlinear coupling among gravity surface waves, we developed an experiment in the Coriolis facility which is a 13-m diameter circular tank. An isotropic and statistically stationary wave turbulence of average steepness of 10\% is maintained by two wedge wave makers. The space and time resolved wave elevation is measured using a stereoscopic technique. Wave-wave interactions are analyzed through third and fourth order correlations. We investigate specifically the role of bound waves generated by non resonant 3-wave coupling. Specifically, we implement a space-time filter to separate the dynamics of free waves (i.e. following the dispersion relation) from the bound waves. We observe that the free wave dynamics causes weak resonant 4-wave correlations. A weak level of correlation is actually the basis of the Weak Turbulence Theory. Thus our observations support the use of the Weak Turbulence to model gravity wave turbulence as is currently been done in the operational models of wave forecasting. Although in the theory bound waves are not supposed to contribute to the energy cascade, our observation raises the question of the impact of bound waves on dissipation and thus on energy transfers as well.

description: We argue that the `changing look' AGN recently reported by LaMassa et al. could be a luminous flare produced by the tidal disruption of a super-solar mass star passing just a few gravitational radii outside the event horizon of a $\sim 10^8 M_{\odot}$ nuclear black hole. This flare occurred in a massive, star forming galaxy at redshift $z=0.312$, robustly characterized thanks to repeated late-time photometric and spectroscopic observations. By taking difference-photometry of the well sampled multi-year SDSS Stripe-82 light-curve, we are able to probe the evolution of the nuclear spectrum over the course of the outburst. The tidal disruption event (TDE) interpretation is consistent with the very rapid rise and the decay time of the flare, which displays an evolution consistent with the well-known $t^{-5/3}$ behaviour (with a clear superimposed re-brightening flare). Our analysis places constraints on the physical properties of the TDE, such as the putative disrupted star's mass and orbital parameters, as well as the size and temperature of the emitting material. The properties of the broad and narrow emission lines observed in two epochs of SDSS spectra provide further constraints on the circum-nuclear structure, and could be indicative that the system hosted a moderate-luminosity AGN as recently as a few $10^4$ years ago, and is likely undergoing residual accretion as late as ten years after peak, as seen from the broad H$α$ emission line. We discuss the complex interplay between tidal disruption events and gas accretion episodes in galactic nuclei, highlighting the implications for future TDE searches and for estimates of their intrinsic rates.

description: Recent years have witnessed increasing food product differentiation, also involving those products that can be termed mature. One example is pasta, a well-integrated product in the daily consumption habits of Italians. In this case, product differentiation has increasingly focused on extrinsic attributes. In our study we analysed the WTP of consumers for the attributes that define pasta. We used a choice model experiment to elicit consumer preferences on the basis of actual and not hypothetical choices as usually occurs. Analysis of the results generated three main considerations: first, real choices led to WTPs consistent with the market price of the products; secondly, brand and label emerged as the most important attributes in the choice; finally, a considerable share of consumers is willing to pay a premium price for what are perceived as quality attributes. This suggests that further market opportunities exist for pasta products.
A Review of Single-Use and Reusable Gowns and Drapes in Health Care

description: Gowns and drapes are used widely in healthcare facilities. Gowns have been used to minimize the risk of disease acquisition by healthcare providers, to reduce the risk of patient-to-patient transmission, and during invasive procedures to aid in maintaining a sterile field. Drapes have been used during invasive procedures to maintain the sterility of environmental surfaces, equipment, and patients. This article reviews the use of gowns and drapes in healthcare facilities, including the characteristics, costs, benefits, and barrier effectiveness of single-use and reusable products. Currently, gowns protect healthcare personnel performing invasive procedures from contact with bloodborne pathogens. Although gowns have been recommended to prevent patient-to-patient transmission in certain settings (eg, neonatal intensive care unit) and for certain patients (eg, those infected with vancomycin-resistant enterococci), scientific studies have produced mixed results of their efficacy. While appropriate use of drapes during invasive procedures is recommended widely as an aid in minimizing contamination of the operative field, the efficacy of this practice in reducing surgical-site infections has not been assessed by scientific studies. Based on an evaluation of the functional requirements, environmental impact, and economics of gowns and drapes, clear superiority of either reusable or single-use gowns and drapes cannot be demonstrated. The selection of particular gowns and drapes by individual healthcare facilities requires an assessment of the facility's requirements, available products, and costs and should be based on the desired characteristics of an ideal gown or drape as defined in this paper.

description: It is estimated that healthcare-associated infections (HAIs) account for approximately 1.7 million infections and 99,000 deaths in US hospitals each year. The Centers for Disease Control and Prevention (CDC) and the National Healthcare Safety Network (NHSN) have developed standardized surveillance definitions of HAIs including surgical site infection (SSI), pneumonia, bloodstream infection (BSI), and urinary tract infection (UTI).2 All HAIs except for these "big four" infection types are categorized as "other" types of HAI. Of the estimated numbers of total HAIs (1,195,142) and deaths associated with HAI (98,987) in US hospitals among adults and children outside of intensive care units (ICUs), other types of HAI accounted for 22% (263,810) and 11% (11,062) of deaths, respectively, which suggests that other HAIs represent a substantial burden in US healthcare facilities.

The exact solution of the model permits to analyse the influence of the spin-anisotropy on the phase diagram and the universality of the critical behaviour in a new way, since the interactions of the quantum spins and their conjugate momenta create new effects. At zero temperature, a quantum critical line is found, which is in the same universality class as the thermal phase transition in the classical spherical model in $d+1$ dimensions. The location of this quantum critical line shows a re-entrant quantum phase transition for dimensions $1

title: Keats: women, readers and revision
Creators: name: Park, Hye-Young
Publisher: name: University of Glasgow
Year: 2000

description: This thesis examines three apparently unrelated matters, Keats's representation of women in his poems, his responses to his readership, and his habits of revision, and argues that these are in fact aspects of Keats's work that are intimately connected one with another. It is divided into three parts. The first part is introductory. In the first chapter I place my own work in relation to the recent trends in Keats criticism that have impinged on it most forcibly. In particular, I consider the recent work, best represented perhaps by Susan Wolfson, that has countered the traditional emphases of Keatsean scholarship by developing an approach that might loosely be described as feminist, and the work, best represented by Andrew Bennett, that has focused on Keats's responses both to the assumed readers of his poems and to their reviewers, most importantly their hostile reviewers. The two critical approaches are connected, as Wolfson amongst others notes, by the fact that during the course of Keats's professional career women became, and were recognised as having become, a constituency of the poetry reading public so powerful as to determine the commercial success of any volume of poetry. My second chapter is biographical. In it, I attempt to ground Keats's complex responses to women in the material, social realities of his life by examining his relationship with three women in particular: Jane Cox, Isabella Jones, and Fanny Brawne, although I call attention also to the striking absence in Keats's writing of a fourth woman, his mother. The division between the second and third parts of the thesis borrows Andrew Bennett's understanding of the distinction between narrative poetry, which is always and explicitly addressed to a reader, and lyric poetry, in which the poet sings to himself and is only overheard by his reader. In the second part of the thesis I treat, in chronological order of their composition, Keats's major narrative romances; Endymion, 'La Belle Dame sans Merci', Isabella, The Eve of St Agnes, Lamia, and the two versions of Hyperion. In the final part of the thesis, I turn to Keats's lyric poems, first the great odes and then the sonnets that Keats wrote at the very end of his poetic career. Of ail Keats's poems the odes have received the fullest critical treatment. My own study of them is distinctive in that it understands Keats's practice in these poems in relation to his handling of the romance form. It follows that for me the 'Ode to Psyche' is the critical poem, because Keats chooses a topic that lends itself to treatment in the form of a verse romance such as Endymion, and had indeed already given Mary Tighe the subject matter for one of the more popular verse romances of Keats's day, and self-consciously refuses the possibility. The visionary encounter with the goddess does not yield a narrative, but rather a still tableau in contemplating which Keats comes to apprehend the nature of his own poetic authority.

description: Background: Previous studies have recommended the use of re-warm-up activities in team sports due to the rapid loss of muscle temperature during periods of inactivity. The aim of this study was to evaluate the effects of a half-time re-warm-up strategy in female basketball players. Materials and Methods: Ten female basketball players U14, separated into 2 teams of 5 players, completed a passive rest intervention (control group) or alternative strategy based on repeat sprint (5x14m) followed 2 min of shooting wheel (re-warm-up group). These interventions were performed during the half-time break (10-min) of a simulated basketball game, where only the first three quarters were played. Conclusion: Performing re-warm-up activities based on sprint could be a valuable strategy to avoid the reduction of sport performance during prolonged breaks, but given the limitations of the study, these relationships need to be further explored in official competitions.

This allows us to prove Seifert-Torres type formulas for certain splice links using quantum algebraic methods, rather than topological methods. Other applications of this diagrammatic calculus given here are a skein relation for $n$-cabled double crossings and a simple proof that the quantum invariant associated with these representations determines the multivariable Alexander polynomial.

description: Transmission of organisms within the hospital setting has become a topic of major concern not only for patients and healthcare facilities but also for government agencies and the general public. This increased awareness has occurred in part due to the spread of organisms that have limited treatment options, such as carbapenem-resistant Enterobacteriaceae (CRE), as well as the heightened recognition that many hospital-associated infections (HAIs) are preventable. A large body of literature shows that horizontal transmission of multidrug-resistant organisms involves the hands, and potentially the attire, of healthcare workers (HCWs). This evidence provides the rationale for the use of standard and contact isolation precautions among HCWs. However, the health risks to visitors and the role of visitors in the horizontal transmission of pathogens within acute care hospitals is not as clearly defined. Consequently, uncertainty remains regarding which precautions visitors should take when interacting with patients placed on isolation precautions. Frequent arguments against the use of isolation precautions among visitors include lack of visitor movement between patient rooms, the difficulty of educating visitors, and the difficulty of enforcing compliance with isolation practices.

description: We prove sharp power-weighted $L^p$, weak type and restricted weak type inequalities for the heat semigroup maximal operator and Riesz transforms associated with the Bessel operator $B_ν$ in the exotic range of the parameter $-\infty < ν< 1$. Moreover, in the same framework, we characterize basic mapping properties for other fundamental harmonic analysis operators, including the heat semigroup based vertical $g$-function and fractional integrals (Riesz potential operators).

description: OBJECTIVE Targeted surveillance has focused on device-associated infections and surgical site infections (SSIs) and is often limited to healthcare-associated infections (HAIs) in high-risk areas. Longitudinal trends in all HAIs, including other types of HAIs, and HAIs outside of intensive care units (ICUs) remain unclear. We examined the incidences of all HAIs using comprehensive hospital-wide surveillance over a 12-year period (2001–2012). METHODS This retrospective observational study was conducted at the University of North Carolina (UNC) Hospitals, a tertiary care academic facility. All HAIs, including 5 major infections with 14 specific infection sites as defined using CDC criteria, were ascertained through comprehensive hospital-wide surveillance. Generalized linear models were used to examine the incidence rate difference by infection type over time. RESULTS A total of 16,579 HAIs included 6,397 cases in ICUs and 10,182 cases outside ICUs. The incidence of overall HAIs decreased significantly hospital-wide (−3.4 infections per 1,000 patient days), in ICUs (−8.4 infections per 1,000 patient days), and in non-ICU settings (−1.9 infections per 1,000 patient days). The incidences of bloodstream infection, urinary tract infection, and pneumonia in hospital-wide settings decreased significantly, but the incidences of SSI and lower respiratory tract infection remained unchanged. The incidence of Clostridium difficile infection (CDI) increased remarkably. The outcomes were estimated to include 700 overall HAIs prevented, 40 lives saved, and cost savings in excess of $10 million. CONCLUSIONS We demonstrated success in reducing overall HAIs over a 12-year period. Our data underscore the necessity for surveillance and infection prevention interventions outside of the ICUs, for non–device-associated HAIs, and for CDI.

description: We investigate experimentally stratified turbulence forced by waves. Stratified turbulence is present in oceans and it is expected to be dominated by nonlinear interaction of internal gravity waves as described by the Garrett & Munk spectrum. In order to reach turbulent regimes dominated by stratification we use the Coriolis facility in Grenoble (France) which large size enables us to reach regimes with both low Froude number and large Reynolds number. Stratification is obtained by using vertically linearly varying salt concentration and we force large scale waves in a $6\times6\times 1$ m$^3$ domain. We perform time-resolved PIV to probe the space-time structure of the velocity field. We observe a wide band spectrum which is made of waves. Discrete modes are observed due to the square shape of the flow container as well as a continuum part which appears consistent with an axisymmetric superposition of random weakly nonlinear waves. Our observations support the interpretation of turbulence of a strongly stratified fluid as wave turbulence of internal waves although our spectrum is quite different from the Garrett & Munk spectrum. Weak turbulence proceeds down to a small cutoff length scale (the buoyancy wavelength) at which a transition to more strongly nonlinear turbulence is expected.

description: Classically, the quantity of contact area $A_R$ between two bodies is considered a proxy for the force of friction. However, bond density across the interface - quality of contact - is also relevant, and contemporary debate often centers around the relative importance of these two factors. In this work, we demonstrate that a third factor, often overlooked, plays a significant role in static frictional strength: the distribution of contact. We perform static friction measurements, $μ$, on three pairs of solid blocks while imaging the contact plane. By using linear regression on hundreds of image-$μ$ pairs, we are able to predict future friction measurements with 3 to 7 times better accuracy than existing benchmarks, including total quantity of contact area. Our model has no access to quality of contact, and we therefore conclude that a large portion of the interfacial state is encoded in the spatial distribution of contact, rather than its quality or quantity.

description: Cancer survivors experience high levels of distress, associated with a host of negative psychological states, including anxiety, depression, and fear of recurrence, which often lead to sleep problems and reduction in quality of life (QOL) and well-being. As a neuropeptide hormone associated with affiliation, calmness, and well-being, oxytocin may be a useful biological measure of changes in health outcomes in cancer survivors. In this exploratory study, which comprised a subset of participants from a larger study, we evaluated ( a ) the feasibility and reliability of salivary oxytocin (sOT) levels in cancer survivors and ( b ) the effects of 2 sleep-focused mind–body interventions, mind–body bridging (MBB) and mindfulness meditation (MM), compared with a sleep hygiene education (SHE) control, on changes in sOT levels in 30 cancer survivors with self-reported sleep disturbance. Interventions were conducted in 3 sessions, once per week for 3 weeks. Saliva samples were collected at baseline, postintervention (~1 week after the last session), and at the 2-month follow-up. In this cancer survivor group, we found that intra-individual sOT levels were fairly stable across the 3 time points, of about 3 months’ duration, and mean baseline sOT levels did not differ between females and males and were not correlated with age. Correlations between baseline sOT and self-report measures were weak; however, several of these relationships were in the predicted direction, in which sOT levels were negatively associated with sleep problems and depression and positively associated with cancer-related QOL and well-being. Regarding intervention effects on sOT, baseline-subtracted sOT levels were significantly larger at postintervention in the MBB group as compared with those in SHE. In this sample of cancer survivors assessed for sOT, at postintervention, greater reductions in sleep problems were noted for MBB and MM compared with that of SHE, and increases in mindfulness and self-compassion were observed in the MBB group compared with those in SHE. The findings in this exploratory study suggest that sOT may be a reliable biological measure over time that may provide insight into the effects of mind–body interventions on health outcomes in cancer survivors.

description: The completeness of binocular rivalry suppression was measured by recording the fraction of a trial during which targets were perceived as alternating in their entirety, rather than blending together into a composite. It was found that the completeness of rivalry declines with prolonged stimulation. A control condition in which subjects saw the same grating targets, but without rivalry, resulted in no decrement. The phenomenon was spatial-frequency specific. The results suggest that binocular rivalry suppression is mediated by a cooperative mechanism which is susceptible to adaptation.
