The affine cohomology spaces and its applications

We compute the [Formula: see text] cohomology space of the affine Lie superalgebra [Formula: see text] on the (1,1)-dimensional real superspace with coefficient in a large class of [Formula: see text]-modules [Formula: see text]. We apply our results to the module of weight densities and the module of linear differential operators acting on a superspace of weighted densities. This work is the generalization of a result by Basdouri et al. [The linear [Formula: see text]-invariant differential operators on weighted densities on the superspace [Formula: see text] and [Formula: see text]-relative cohomology, Int. J. Geom. Meth. Mod.

A general Kastler–Kalau–Walze type theorem for manifolds with boundary

In this paper, we establish a general Kastler–Kalau–Walze type theorem for any dimensional manifolds with boundary which generalizes the results in [Y. Wang, Lower-dimensional volumes and Kastler–Kalau–Walze type theorem for manifolds with boundary, Commun. Theor. Phys. 54 (2010) 38–42]. This solves a problem of the referee of [J. Wang and Y. Wang, A Kastler–Kalau–Walze type theorem for five-dimensional manifolds with boundary, Int. J. Geom. Meth. Mod. Phys. 12(5) (2015), Article ID: 1550064, 34 pp.], which is a general expression of the lower dimensional volumes in terms of the geometric data on the manifold.

Maximal isotropic subbundles of orthogonal bundles of odd rank over a curve

An orthogonal bundle over a curve has an isotropic Segre invariant determined by the maximal degree of a maximal isotropic subbundle. This invariant and the induced stratifications on moduli spaces of orthogonal bundles were studied for bundles of even rank in [I. Choe and G. H. Hitching, A stratification on the moduli space of symplectic and orthogonal bundles over a curve, Internat. J. Math. 25(5) (2014), Article ID: 1450047, 27pp.]. In this paper, we obtain analogous results for bundles of odd rank. We compute the sharp upper bound on the isotropic Segre invariant. Also we show the irreducibility of the induced strata on the moduli spaces of orthogonal bundles of odd rank, and compute their dimensions.

Multiple positive solutions for a class of concave–convex elliptic problems in ℝNinvolving sign-changing weight, II

In this paper, we study the following concave–convex elliptic problems: [Formula: see text] where N ≥ 3, 1 < q < 2 < p < 2* = 2N/(N - 2), λ > 0 and μ < 0 are two parameters. By using several variational methods and a perturbation argument, we obtain three positive solutions to this problem under the predefined conditions of fλ(x) and gμ(x), which simultaneously extends the result of [T. Hsu, Multiple positive solutions for a class of concave–convex semilinear elliptic equations in unbounded domains with sign-changing weights, Bound. Value Probl. 2010 (2010), Article ID 856932, 18pp.; T. Wu, Multiple positive solutions for a class of concave–convex elliptic problems in ℝNinvolving sign-changing weight, J. Funct. Anal. 258 (2010) 99–131]. We also study the concentration behavior of these three solutions both for λ → 0 and μ → -∞.

Larger and More Severe Strokes Seen With Aspirin Resistance

Patients with acute ischemic stroke who test positive for aspirin resistance had both larger stroke volume and increased severity, compared with patients without resistance, in an observational study of 311 patients at Korean medical centers. Given that previous studies have shown that the use of aspirin is associated with lower stroke severity and decreased infarction growth, the current study's findings may help to define the effect of aspirin resistance (AR) on stroke severity, since previous studies had provided inconclusive results, Mi Sun Oh, MD, and colleagues at Hallym University Sacred Heart Hospital, Anyang, South Korea, wrote in their abstract. The findings were released in advance of the annual meeting of the American Academy of Neurology. The investigators enrolled patients with acute ischemic stroke confirmed by diffusion-weighted imaging (DWI) who had received at least 7 days of aspirin therapy before initial stroke symptoms and had been checked for AR within 24 hours of hospital admission. Patients with high prestroke disability scores (modified Rankin Scale score > 2) were excluded, as were those who were taking another antiplatelet or anticoagulant medication concurrently with aspirin on hospital admission. Enrollees were deemed aspirin resistant if a rapid assay detected greater than 550 Aspirin Reaction Units. DWI-observed stroke volume was assessed via a semiautomated threshold technique, and investigators employed the National Institutes of Health Stroke Scale (NIHSS) score to measure initial stroke severity. Aspirin resistance may be either a laboratory-defined lack of inhibition of thromboxane A2, or a clinically defined entity. In either case, a host of factors may contribute. Seventy-eight of the 311 patients (25.1%) had AR. Dr. Oh and colleagues reported that median stroke volume was higher for these patients, compared with the aspirin-sensitive group (2.8 cc vs. 1.6 cc), as was least-square mean on multivariate analysis. Median NIHSS scores were also higher for the AR group (4 vs. 3), indicating greater stroke severity, a result that was confirmed by multivariate analysis. Aspirin resistance is a complicated and heterogeneous concept, and not a well defined entity, according to vascular neurologist Philip Gorelick, MD, head of the Hauenstein Neuroscience Center at St. Mary's Health Care in Grand Rapids, MI. Dr. Gorelick is an honorary member of the Korean Stroke Society but was not involved in the present study. In an interview, he expanded on the diverse mechanisms that can impede the stroke prevention effect of antiplatelet agents such as aspirin (Stroke Res Treat 2013;Article ID 727842 [doi:10.1155/2013/727842]). In contrast to the traditional notion of “resistance” as an inherent or acquired defense or chemical blockage of a drug, whether by a microbe or the host, aspirin resistance may be either a laboratory-defined lack of inhibition of thromboxane A2, or a clinically defined entity. In either case, a host of factors may contribute, Dr. Gorelick said. Poor adherence to an aspirin therapy regimen may be a primary contributor to AR. Further, enterically coated aspirin may not be as well absorbed in the gut, leading to lower effective aspirin dosing. A host of other factors, including concurrent medication administration, comorbidities impacting platelet turnover, and genetic polymorphisms may also contribute to aspirin failure. Although patient characteristics were not reported in this study, Dr. Gorelick did issue a general note of caution: “Another major issue in these types of studies,” he noted, is to determine if “patients are similar in terms of background factors. Patients on aspirin therapy may be more likely to have more severe preexisting vascular disease,” predisposing them to more severe stroke. The Korea Healthcare Technology R&D Project, Ministry of Health and Family Welfare, and the Republic of Korea supported the study. The authors had no disclosures.

The Rate Limiting Step (RLS) for the Oxygen Reduction Reaction at the Cathode of Polymer Electrolyte Membrane Fuel Cell

Proton exchange membrane fuel cells (PEMFCs) can be operated by hydrogen and pure oxygen (not air) by in-situ photo-catalytic splitting of water (gasoline of the future). Recently, several auto makers have introduced H2-fed fuel cell vehicles on the road. However, some concerns, i.e., catalyst and membrane’s cost and durability, catalyst activity, membrane proton conductivity, and water management, still exist. In order to make the fuel cell vehicle affordable and durable, further work needs to be done to improve each of the above mentioned aspects [1]. In a recent review by Ramaswamy and Mukerjee [2] have shown that the mechanism proposed by Damjanovic et al. describes the rate RLS. The purpose of this publication is to show that the rate limiting step for the ORR at the cathode of PEMFC is the rate of dissolution of gases oxygen in the aqueous media. It is well known that the Henry constant for oxygen in aqueous solutions is very low at range of temperature between 60 to 80 ̊ C (figure 1). The second purpose is to derive an equation that shows the strong relationship between the mass transfer coefficient and oxygen solubility. Strong supports for such a mechanism are: 1-In 2010 Erlebacher and co-workers [3] discovered a new ionic liquid that has strong affinity to absorb oxygen and were used to improve the rate of ORR. 2- The enhancement of the rate of ORR after humidification of the cathodic region (humid air contains dissolved oxygen) while humidification of the anodic region (can humidify the membrane and increase its conductivity) has no effect on the rate of ORR [4-6] 1-Perry M.L. and Fuller T.F., Journal of the Electrochemical Society 149, S59 (2002) 2-Ramaswamy N., and Mukerjee S.

Application of the factorization method to retrieve a crack from near field data

Abstract We consider the inverse scattering problem of determining the shape of a crack with impedance boundary condition on one side from the complex conjugate of point sources placed on a closed curve which contains the crack. The near field factorization method is established to reconstruct the crack from the measurements on the same curve. Then, we deduce an inversion algorithm and present some numerical examples to show the viability of our method. So far as we know, when the incident waves are the point sources, the near field operator cannot be directly decomposed into the form that the factorization method required. However, we overcome this difficulty with the complex conjugate of point sources which are recently used in [Inverse Problems 30 (2014), Article ID 095005], [Inverse Problems 30 (2014), Article ID 045008] for the justification of the factorization method from near field data.

New solitary solutions and a conservative numerical method for the Rosenau–Kawahara equation with power law nonlinearity

Recently, Biswas et al. (Phys Wave Phenom 19:24–29, 2011) derived exact bright and dark solitary solutions for the Rosenau–Kawahara equation with power law nonlinearity, and Hu et al. (Adv Math Phys 11, Article ID 217393, 2014) proposed two conservative finite difference schemes for the usual Rosenau–Kawahara equation. In this paper, we obtain another set of exact solitary solutions for the Rosenau–Kawahara equation with power law nonlinearity. More importantly, a conservative finite difference method is presented. The fundamental energy conservation law is preserved by the current numerical scheme. And the existence and uniqueness of the numerical solution are proved. The convergence and stability of the numerical solution are also shown. The method is second-order convergent both in time and in space. Finally, numerical results confirm well with the theoretical results and show that the current method can be well used to study the solitary wave at long time.

PTU-006 Glove port trans anal excision of rectal tumours

Introduction Transanal glove port excision is a safe minimally invasive procedure for excising rectal tumours that avoids major rectal surgeries and its complications. The aim of this study is to review a single Centre experience with Trans Anal Glove Port excision of rectal tumours. Method Between 2011–2014, 11 patients underwent resection of benign (N = 9) or Malignant (N = 2) rectal tumours, located above the dentate line to 14 cm. The mean follow up period was between 6–12 months. Glove port was constructed using circular anal dilator, standard surgical glove and a wound protector retractor. Results All the patients underwent Glove port transanal excision of rectal tumours. Male: Female ratio was 10:1. Average age of patients was 63 years. None of the patients in the series underwent conversion to radical surgery. Full thickness excision of the tumour was performed in 9 patients and the other two underwent submucosal excision. During the follow up period between 6–12 months, 1 patient had recurrent tubulo villous adenoma, which needed further excision of the adenoma. In two patients who had a planned glove port excision for a presumed benign rectal polyp (Tubulo villous adenoma), The final histology showed an adenocarcinoma on a background of Tubulo-villous adenoma. Both the Patients underwent further staging investigations, one patient had a further chemo-radiotherapy and the other patient did not need any further treatment. Both are under close surveillance with no recurrence. Post-operative complications were only mild which included bleeding and mucus discharge. Conclusion Glove port Trans anal excision is a safe, effective and cheap technique useful in excising rectal tumours with good clearance and full thickness excision of the rectal wall where necessary. It helps avoid major rectal resections with its attendant complications, in many cases. Disclosure of interest None Declared. Reference Alessandro C, Daniela M, Michele M, et al .

Vertex criticality with respect to isolate domination

A set S of vertices of a graph G is called a dominating set of G if every vertex in V(G) - S is adjacent to a vertex in S. A dominating set S such that the subgraph 〈S〉 induced by S has at least one isolated vertex is called an isolate dominating set. The minimum cardinality of an isolate dominating set is called the isolate domination number and is denoted by γ0(G). This concept was introduced in [I. Sahul Hamid and S. Balamurugan, Isolate domination in graphs (Communicated)] and further studied in [I. Sahul Hamid and S. Balamurugan, Extended chain of domination parameters in graphs, ISRN Combin. 2013 (2013), Article ID: 792743, 4 pp.; Isolate domination and maximum degree, Bull. Int. Math. Virtual Inst. 3 (2013) 127–133; Isolate domination in unicyclic graphs, Int. J. Math. Soft Comput. 3(3) (2013) 79–83]. This paper studies the effect of the removal of a vertex upon the isolate domination number.
