description: We study meromorphic extensions of distance and tube zeta functions, as well as of geometric zeta functions of fractal strings. The distance zeta function $ζ_A(s):=\int_{A_δ} d(x,A)^{s-N}\mathrm{d}x$, where $δ>0$ is fixed and $d(x,A)$ denotes the Euclidean distance from $x$ to $A$ extends the definition of the zeta function associated with bounded fractal strings to arbitrary bounded subsets $A$ of $\mathbb{R}^N$. The abscissa of Lebesgue convergence $D(ζ_A)$ coincides with $D:=\overline\dim_BA$, the upper box dimension of $A$. The complex dimensions of $A$ are the poles of the meromorphic continuation of the fractal zeta function of $A$ to a suitable connected neighborhood of the "critical line" $\{\Re(s)=D\}$. We establish several meromorphic extension results, assuming some suitable information about the second term of the asymptotic expansion of the tube function $|A_t|$ as $t\to0^+$, where $A_t$ is the Euclidean $t$-neighborhood of $A$. We pay particular attention to a class of Minkowski measurable sets, such that $|A_t|=t^{N-D}(\mathcal M+O(t^γ))$ as $t\to0^+$, with $γ>0$, and to a class of Minkowski nonmeasurable sets, such that $|A_t|=t^{N-D}(G(\log t^{-1})+O(t^γ))$ as $t\to0^+$, where $G$ is a nonconstant periodic function and $γ>0$. In both cases, we show that $ζ_A$ can be meromorphically extended (at least) to the open right half-plane $\{\Re(s)>D-γ\}$. Furthermore, up to a multiplicative constant, the residue of $ζ_A$ evaluated at $s=D$ is shown to be equal to $\mathcal M$ (the Minkowski content of $A$) and to the mean value of $G$ (the average Minkowski content of $A$), respectively. Moreover, we construct a class of fractal strings with principal complex dimensions of any prescribed order, as well as with an infinite number of essential singularities on the critical line $\{\Re(s)=D\}$.

The role of Toll/interleukin-1 receptor adaptor protein in the pathogenesis of myelodysplastic syndromes
Creators: name: Ibrahim, Rawa
Publisher: name: University of British Columbia
Year: 2016

description: Hematopoiesis is a process essential for the maintenance of cells that mediate many vital functions such as the production of red blood cells necessary for transportation of oxygen and the removal of carbon dioxide from the body. It is also required for the production of platelets which are necessary for clotting, and the various types of white blood cells that make up the innate and adaptive immune systems that protect against viral, microbial, and parasitic infections. The cell responsible for the generation of all the downstream effector cells, the hematopoietic stem cell (HSC), is generated during embryogenesis. Through a series of symmetric and asymmetric cell divisions, the HSC is capable of maintaining all the cells of the hematopoietic hierarchy throughout the lifespan of an organism. A variety of genetic and epigenetic cues are necessary to maintain homeostasis, and perturbations in these cues lead to the development of hematopoietic malignancies and myelodysplastic syndromes. In recent years the innate immune pathway has emerged as an important player in hematopoietic homeostasis. This dissertation examines the role of dysregulation of innate immune signaling in the development of the myelodysplastic syndromes, one of the most common hematological malignancies. Using a murine bone marrow transplantation assay, I show that overexpression of the innate immune signaling adaptor, TIRAP, results in perturbations in normal hematopoiesis. Overexpression of TIRAP in the hematopoietic compartment results in an inability to produce mature hematopoietic cells, leading to pancytopenia and bone marrow failure (BMF). TIRAP-induced BMF is a result of both autonomous and non-autonomous effects mediated by the cytokine IFNγ. Interestingly, in an environment depleted of IFNγ, TIRAP-transplanted mice develop a myeloproliferative neoplasm suggesting that TIRAP activates both myelosuppressive pathways (through IFNγ) as well as myeloproliferative pathways. IFNγ acts in a paracrine manner inhibiting osteoclast proliferation and maturation in the bone marrow microenvironment, thus disrupting the HSC niche. In summary, this thesis shows the importance of immune regulation in hematopoietic homeostasis. Furthermore, it shows how defects in the hematopoietic stem/progenitor compartment can translate into a defect in the stem cell niche, contributing further to marrow failure and disease progression.

description: During the First World War, hundreds of thousands of men found themselves interned in Britain. These were made up of: civilians already present in the country in August 1914; civilians brought to Britain from all over the world; and combatants, primarily soldiers from the Western Front, but also naval personnel and a few members of zeppelin crews, whose vessels fell to earth. Prisoners were interned in a large number of locations, and could spend years behind barbed wire away from families. The following article provides an outline of the history of internment in Britain during the Great War.

description: This article describes the business development and the opportunities and risks that Swiss companies faced during the First World War. Although the export industries that supplied essential products to the warring nations for the most part reported high profits, the war posed a major challenge for the domestic economy and companies whose services or products were not essential for the conflict. The wide-scale export of war materials and, in some cases, the substantial profits that this business generated were curtailed by extensive control measures and a gradual loss of economic freedom. In Switzerland, the increasingly aggressive eco­nomic war triggered price increases and rising hardship across society. In the second half of the war, the number of strike days rose sharply, and there was widespread anger at the war profiteers, usurers and speculators. In November 1918, the Swiss national strike sparked the most serious social and domestic political crisis since the confederation was founded in 1848.

description: A categorification of the Beilinson-Lusztig-MacPherson form of the quantum sl(2) was constructed in the paper arXiv:0803.3652 by the second author. Here we enhance the graphical calculus introduced and developed in that paper to include two-morphisms between divided powers one-morphisms and their compositions. We obtain explicit diagrammatical formulas for the decomposition of products of divided powers one-morphisms as direct sums of indecomposable one-morphisms; the latter are in a bijection with the Lusztig canonical basis elements. These formulas have integral coefficients and imply that one of the main results of Lauda's paper---identification of the Grothendieck ring of his 2-category with the idempotented quantum sl(2)---also holds when the 2-category is defined over the ring of integers rather than over a field.

description: We establish pointwise and distributional fractal tube formulas for a large class of relative fractal drums in Euclidean spaces of arbitrary dimensions. A relative fractal drum (or RFD, in short) is an ordered pair $(A,Ω)$ of subsets of the Euclidean space (under some mild assumptions) which generalizes the notion of a (compact) subset and that of a fractal string. By a fractal tube formula for an RFD $(A,Ω)$, we mean an explicit expression for the volume of the $t$-neighborhood of $A$ intersected by $Ω$ as a sum of residues of a suitable meromorphic function (here, a fractal zeta function) over the complex dimensions of the RFD $(A,Ω)$. The complex dimensions of an RFD are defined as the poles of its meromorphically continued fractal zeta function (namely, the distance or the tube zeta function), which generalizes the well-known geometric zeta function for fractal strings. These fractal tube formulas generalize in a significant way to higher dimensions the corresponding ones previously obtained for fractal strings by the first author and van Frankenhuijsen and later on, by the first author, Pearse and Winter in the case of fractal sprays. They are illustrated by several interesting examples. These examples include fractal strings, the Sierpiński gasket and the 3-dimensional carpet, fractal nests and geometric chirps, as well as self-similar fractal sprays. We also propose a new definition of fractality according to which a bounded set (or RFD) is considered to be fractal if it possesses at least one nonreal complex dimension or if its fractal zeta function possesses a natural boundary. This definition, which extends to RFDs and arbitrary bounded subsets of $\mathbb{R}^N$ the previous one introduced in the context of fractal strings, is illustrated by the Cantor graph (or devil's staircase) RFD, which is shown to be `subcritically fractal'.

description: Ceramics are part of the material dimension of practice, inserted into a process by which human objects and agents are reciprocally constituted. In this way, both daily activities and everyday objects are socially significant. Therefore, it is necessary to focus on a broader aspect of social life that goes beyond “the symbolic”. In this sense, a comprehensive ceramic analysis that integrates stylistic, technological and functional aspects is relevant to understand social, symbolic and ideological dimensions in everyday activities of the groups that developed and consumed ceramic vessels. Within this framework, the interrelated analysis of functional, technological, morphological and iconographic aspects allows understanding how a particular way of doing was configured and use. Angosto Chico Inciso was considered one of the local late pre-Hispanic ceramic styles of Quebrada de Humahuaca (North of Argentina), although its foreign origins and the great variety within the style was soon evidenced. Recent petrographic studies have shown that these vessels present both a local and foreign manufacture. In this paper we present the analysis of Angosto Chico Inciso ceramics recovered in a sector of Quebrada de Humahuaca, considering diverse approaches to determine the stylistic variety within this group of vessels, their technological traits and the function they could have had in different pre-Hispanic moments. Stylistic studies that consider iconographic and morphological aspects, technological and use-wear analysis were carried out in 38 fragmented vessels from Esquina de Huajra, Pucara de Volcán, and El Pobladito sites, covering pre-Inca and Inca occupations. Studies determined the production and use of Angosto Chico Inciso vessels as early as the 13th century, both in domestic and public contexts. These vessels correspond to local and non-local manufacturing. Stylistic and technological studies have revealed the presence of two modalities of Angosto Chico Inciso that correspond to the two different manufactures.

description: We present the non-linear theory of shock acceleration applied to SNRs expanding into partially neutral plasma. Using this theory we show how the Balmer lines detected from young SNRs can be used to test the efficiency of shocks in the production of cosmic rays. In particular we investigate the effect of charge-exchange between protons and neutral hydrogen occurring in the precursor formed ahead of the shock. In this precursor the CR pressure accelerate the ionized component of the plasma and a relative velocity between protons and neutral hydrogen is established. On the other hand the charge-exchange process tends to equilibrate ions and neutrals resulting in the heating of both components. We show that even when the shock converts only a few per cent of the total bulk kinetic energy into CRs, the heating is efficient enough to produce a detectable broadening of the narrow Balmer lines emitted by the neutral hydrogen.

description: Point-contact (PC) Andreev-reflection (AR) measurements of the superconducting gap in iron-oxipnictide ReFeAsO_{1-x}F_x (Re=La, Sm) films have been carried out. The value of the gap is distributed in the range 2Δ\simeq 5-10 meV (for Re=Sm) with a maximum in the distribution around 6 meV. Temperature dependence of the gap Δ(T) can be fitted well by BCS curve giving reduced gap ratio 2Δ/kT_c^*\simeq 3.5 (here T_c^* is the critical temperature from the BCS fit). At the same time, an expected second larger gap feature was difficult to resolve distinctly on the AR spectra making determination reliability of the second gap detection questionable. Possible reasons for this and the origin of other features like clear-cut asymmetry in the AR spectra and current regime in PCs are discussed.

description: We establish a Minkowski measurability criterion for a large class of relative fractal drums (or, in short, RFDs), in Euclidean spaces of arbitrary dimension in terms of their complex dimensions, which are defined as the poles of their associated fractal zeta functions. Relative fractal drums represent a far-reaching generalization of bounded subsets of Euclidean spaces as well as of fractal strings studied extensively by the first author and his collaborators. In fact, the Minkowski measurability criterion established here is a generalization of the corresponding one obtained for fractal strings by the first author and M.\ van Frankenhuijsen. Similarly as in the case of fractal strings, the criterion established here is formulated in terms of the locations of the principal complex dimensions associated with the relative drum under consideration. These complex dimensions are defined as poles or, more generally, singularities of the corresponding distance (or tube) zeta function. We also reflect on the notion of gauge-Minkowski measurability of RFDs and establish several results connecting it to the nature and location of the complex dimensions. (This is especially useful when the underlying scaling does not follow a classic power law.) We illustrate our results and their applications by means of a number of interesting examples.

description: We present a new approach known as greedy segmentation (GS) to identify multiple changepoints for a functional data sequence. The proposed multiple changepoint detection criterion links detectability with the projection onto a suitably chosen subspace and the changepoint locations. The changepoint estimator identifies the true changepoints for any predetermined number of changepoint candidates, either over-reporting or under-reporting. This theoretical finding supports the proposed GS estimator, which can be efficiently obtained in a greedy manner. The GS estimator’s consistency holds without being restricted to the conventional at most one changepoint condition, and it is robust to the relative positions of the changepoints. Based on the GS estimator, the test statistic’s asymptotic distribution leads to the novel GS algorithm, which identifies the number and locations of changepoints. Using intensive simulation studies, we compare the finite sample performance of the GS approach with other competing methods. We also apply our method to temporal changepoint detection in weather datasets.

Regulation of macrophage function related to atherosclerosis development
Creators: name: Zhang, Peng
Publisher: name: University of British Columbia
Year: 2015

description: Atherosclerosis has been identified as a chronic inflammatory disease resulting from interactions between immune cells and their microenvironment in the walls of susceptible arteries. Macrophages, critical players in innate immunity, participate in major events throughout all stages of atherosclerosis progression. Work in this dissertation is specifically interested in regulation of macrophage functions in the context of atherosclerosis. First, using bone marrow transplantation, we investigated how loss of eukaryotic elongation factor 2 kinase (eEF2K) activity affected atherosclerosis progression. Compared to mice transplanted with wild-type bone marrow, mice transplanted with bone marrow from eEF2K deficient mice had reduced atherosclerosis development after being fed with high-fat diet for 16 weeks. Impaired tumor necrosis factor-α release and subsequent adhesion molecule expression in the eEF2K inactive group may account for the reduction of atherosclerotic plaques. This finding suggested that the eEF2K inhibitor may be clinically useful to treat atherosclerosis. Second, we examined how oxLDL was involved in macrophage plasticity. We found that oxLDL polarized macrophages towards a novel subtype named MoL, which was characterized by high expression levels of heme oxygenase-1 and macrophage inhibitory cytokine-1. MoL cells are polarized, in part, through the activation of the PI3K/Akt pathway. MoL cells specifically up-regulates vascular cell adhesion molecule-1. This finding provided a more comprehensive view of macrophage plasticity in the context of atherosclerosis. Finally, we investigated signal transduction of ceramide 1-phosphate induced vascular endothelial growth factor release in macrophages. Using pharmaceutical inhibitors, we ruled out contributions of p38 MAPK and PKC-ζ signalling, and showed that the PI3K/Akt and MEK/ERK pathways were responsible for this process. Although we have no solid evidence to conclude on the mechanisms by which signals transduced from the outside of the cell to the inside, a rational hypothesis that this transduction requires ceramide 1-phosphate to be either embedded into, or actively transported through, the plasma membrane has been proposed. In summary, work in this dissertation contributes to our understanding of how macrophages functions are regulated by interacting with factors in the microenvironment. Results from this dissertation provide potential new avenues for discovery of novel therapeutic approaches to treat atherosclerosis.

description: Items from a database are often ranked based on a combination of multiple criteria. A user may have the flexibility to accept combinations that weigh these criteria differently, within limits. On the other hand, this choice of weights can greatly affect the fairness of the produced ranking. In this paper, we develop a system that helps users choose criterion weights that lead to greater fairness. We consider ranking functions that compute the score of each item as a weighted sum of (numeric) attribute values, and then sort items on their score. Each ranking function can be expressed as a vector of weights, or as a point in a multi-dimensional space. For a broad range of fairness criteria, we show how to efficiently identify regions in this space that satisfy these criteria. Using this identification method, our system is able to tell users whether their proposed ranking function satisfies the desired fairness criteria and, if it does not, to suggest the smallest modification that does. We develop user-controllable approximation that and indexing techniques that are applied during preprocessing, and support sub-second response times during the online phase. Our extensive experiments on real datasets demonstrate that our methods are able to find solutions that satisfy fairness criteria effectively and efficiently.

description: Recently, Li et al. proposed a secure biometric-based remote user authentication scheme using smart cards to withstand the security flaws of Li-Hwang's efficient biometric-based remote user authentication scheme using smart cards. Li et al.'s scheme is based on biometrics verification, smart card and one-way hash function, and it also uses the random nonce rather than a synchronized clock, and thus it is efficient in computational cost and more secure than Li-Hwang's scheme. Unfortunately, in this paper we show that Li et al.'s scheme still has some security weaknesses in their design. In order to withstand those weaknesses in their scheme, we further propose an improvement of their scheme so that the improved scheme always provides proper authentication and as a result, it establishes a session key between the user and the server at the end of successful user authentication.

description: Quasi-periodic, propagating fast mode magnetosonic waves in the corona were difficult to observe in the past due to relatively low instrument cadences. We report here evidence of such waves directly imaged in EUV by the new SDO AIA instrument. In the 2010 August 1 C3.2 flare/CME event, we find arc-shaped wave trains of 1-5% intensity variations (lifetime ~200 s) that emanate near the flare kernel and propagate outward up to ~400 Mm along a funnel of coronal loops. Sinusoidal fits to a typical wave train indicate a phase velocity of 2200 +/- 130 km/s. Similar waves propagating in opposite directions are observed in closed loops between two flare ribbons. In the k-$ω$ diagram of the Fourier wave power, we find a bright ridge that represents the dispersion relation and can be well fitted with a straight line passing through the origin. This k-$ω$ ridge shows a broad frequency distribution with indicative power at 5.5, 14.5, and 25.1 mHz. The strongest signal at 5.5 mHz (period 181 s) temporally coincides with quasi-periodic pulsations of the flare, suggesting a common origin. The instantaneous wave energy flux of $(0.1-2.6) \times 10^7 ergs/cm^2/s$ estimated at the coronal base is comparable to the steady-state heating requirement of active region loops.

description: Breast cancer stands out as the most common cancer type among women throughout the world. Especially for the estrogen receptor alpha (ER α +) positive breast cancer cells Tamoxifen has been widely used as an anti-cancer agent. Tamoxifen’s mechanism of action is through ER. It binds to the receptor and leads to a conformational change which eventually prevents cancer cells proliferation and survival. In our current study, we aimed to investigate the combination of Tamoxifen with Vitamin D3 to test whether this combination will enhance the anti-cancer effect of Tamoxifen on breast cancer cells in vitro. Vitamin D3 has sterol structure and this property enables it to act similar to hormones. Vitamin D Receptor (VDR) has been commonly found in different types of cancer cells including but not limited to breast and prostate cancer cells. Through this receptor Vitamin D3 acts as an anti-proliferative agent. We examined the proliferation rate, apoptosis and necrosis levels as well as cell cycle progression in MCF-7 breast cancer cell line in the presence of Vitamin D3 and Tamoxifen to compare the changes with the Tamoxifen treated group. Our results suggest that Tamoxifen was a more potent anti-cancer agent than Vitamin D3 or its combination with Vitamin D3 based on cell cycle arrest, apoptosis and cell proliferation levels. This effect in the apoptosis rate and cell cycle stage of the MCF-7 cells were in line with the changes in gene expression profile of P53, BAX and BCL-2. Our results suggest that Tamoxifen by itself is adequate enough and more potent than Vitamin D3 or its combination with Vitamin D3 as anti-cancer agent for the breast cancer cells in vitro.

description: In this paper an improved version of the graded precision localization algorithm GRADELOC, called IGRADELOC is proposed. The performance of GRADELOC is dependent on the regions formed by the overlapping radio ranges of the nodes of the underlying sensor network. A different region pattern could significantly alter the nature and precision of localization. In IGRADELOC, two improvements are suggested. Firstly, modifications are proposed in the radio range of the fixed-grid nodes, keeping in mind the actual radio range of commonly available nodes, to allow for routing through them. Routing is not addressed by GRADELOC, but is of prime importance to the deployment of any adhoc network, especially sensor networks. A theoretical model expressing the radio range in terms of the cell dimensions of the grid infrastructure is proposed, to help in carrying out a deployment plan which achieves the desirable precision of coarse-grained localization. Secondly, in GRADELOC it is observed that fine-grained localization does not achieve significant performance benefits over coarse-grained localization. In IGRADELOC, this factor is addressed with the introduction of a parameter that could be used to improve and fine-tune the precision of fine-grained localization.

description: Selecting the best items in a dataset is a common task in data exploration. However, the concept of "best" lies in the eyes of the beholder: different users may consider different attributes more important, and hence arrive at different rankings. Nevertheless, one can remove "dominated" items and create a "representative" subset of the data set, comprising the "best items" in it. A Pareto-optimal representative is guaranteed to contain the best item of each possible ranking, but it can be almost as big as the full data. Representative can be found if we relax the requirement to include the best item for every possible user, and instead just limit the users' "regret". Existing work defines regret as the loss in score by limiting consideration to the representative instead of the full data set, for any chosen ranking function. However, the score is often not a meaningful number and users may not understand its absolute value. Sometimes small ranges in score can include large fractions of the data set. In contrast, users do understand the notion of rank ordering. Therefore, alternatively, we consider the position of the items in the ranked list for defining the regret and propose the {\em rank-regret representative} as the minimal subset of the data containing at least one of the top-$k$ of any possible ranking function. This problem is NP-complete. We use the geometric interpretation of items to bound their ranks on ranges of functions and to utilize combinatorial geometry notions for developing effective and efficient approximation algorithms for the problem. Experiments on real datasets demonstrate that we can efficiently find small subsets with small rank-regrets.

description: Using the Wang-Landau flat histogram Monte Carlo (FHMC) simulation technique, we were able to study two types of triangulated spherical surface models in which the two-dimensional extrinsic curvature energy is assumed in the Hamiltonian. The Gaussian bond potential is also included in the Hamiltonian of the first model, but it is replaced by a hard-wall potential in the second model. The results presented in this paper are in good agreement with the results previously reported by our group. The transition of surface fluctuations and collapsing transition were studied using the canonical Metropolis Monte Carlo simulation technique and were found to be of the first-order. The results obtained in this paper also show that the FHMC technique can be successfully applied to triangulated surface models. It is non-trivial whether the technique is applicable or not to surface models because the simulations are performed on relatively large surfaces.

description: Theories of language processing generally assume that speakers construct independent representations for syntactic and semantic information, based largely on evidence from English and related languages. But it is not clear whether the assumption of autonomous syntactic representations extends to other languages with different typological characteristics. We therefore conducted two structural priming studies investigating production of dative sentences in Mandarin, a language whose interpretation appears to be more reliant on non-relational (intrinsic) semantics (e.g. animacy features). We examined whether participants’ tendency to repeat syntax was affected by whether the theme and recipient arguments matched or mismatched in animacy across prime and target. Participants repeated syntax to the same extent irrespective of whether prime and target arguments had matched or mismatched animacy. These findings provide evidence that the separation of syntactic and semantic representations occurs in Mandarin and therefore may occur across languages.

description: A solution to the optimal problem for determining vector fields which maximize (resp. minimize) the transition probabilities from one location to another for a class of reflecting diffusion processes is obtained in the present paper. The approach is based on a representation for the transition probability density functions. The optimal transition probabilities under the constraint that the drift vector field is bounded by a constant are studied in terms of the HJB equation. In dimension one, the optimal reflecting diffusion processes and the bang-bang diffusion processes are considered. We demonstrate by simulations that, even in this special case, the optimal diffusion processes exhibit an interesting feature of phase transitions. We also solve an optimal stochastic control problem for a class of stochastic control problems involving diffusion processes with reflection.

description: We consider (small) algebraic deformations of germs of real-algebraic CR submanifolds in complex space and study the biholomorphic equivalence problem for such deformations. We show that two algebraic deformations of minimal holomorphically nondegenerate real-algebraic CR submanifolds are holomorphically equivalent if and only if they are algebraically equivalent.
The targum (1876:Nov.)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1876

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Data analysis impacts virtually every aspect of our society today. Often, this analysis is performed on an existing dataset, possibly collected through a process that the data scientists had limited control over. The existing data analyzed may not include the complete universe, but it is expected to cover the diversity of items in the universe. Lack of adequate coverage in the dataset can result in undesirable outcomes such as biased decisions and algorithmic racism, as well as creating vulnerabilities such as opening up room for adversarial attacks. In this paper, we assess the coverage of a given dataset over multiple categorical attributes. We first provide efficient techniques for traversing the combinatorial explosion of value combinations to identify any regions of attribute space not adequately covered by the data. Then, we determine the least amount of additional data that must be obtained to resolve this lack of adequate coverage. We confirm the value of our proposal through both theoretical analyses and comprehensive experiments on real data.

description: The first direct measurement of the proton separation energy, Sp, for the proton-unbound nucleus 69Br is reported. Of interest is the exponential dependence of the 2p-capture rate on Sp which can bypass the 68Se waiting-point in the astrophysical rp process. An analysis of the observed proton decay spectrum is given in terms of the 69Se mirror nucleus and the influence of Sp is explored within the context of a single-zone X-ray burst model.
