Authors: Jia Huali , Wang Chunjie , Guo Feng 
Published: August 2014

AbstractThe three‐dimensional (3D) coordination polymer {[Cd2(4,4′‐sdb)2(tib)(H2O)3]·H2O}n (1) [4,4′‐H2sdb = 4,4′‐sulfonyl‐dicarboxylic acid and tib = 1,3,5,‐tris(1‐imidazolyl) benzene] was prepared by the combination of a V‐shaped 4,4′‐sulfonyl‐dicarboxylic acid and neutral organonitrogen coligands. The structure of the neutral polymeric complex 1 was determined by single‐crystal X‐ray diffraction studies. Complex 1 exhibits a twofold interpenetrated (3,3,4)‐connected 3D architecture with the point symbol (6.82).(64.82).(83). In addition, the luminescent property of complex 1 was investigated.
Mesh Repair Versus Non‐Mesh Repair for Strangulated Inguinal Hernia: Systematic Review with Meta‐Analysis
Authors: Hentati Hassen , Dougaz Wajih , Dziri Chadli 
Published: August 2014

AbstractBackgroundThe optimal technique to cure strangulated inguinal hernia remains controversial. The use of mesh in cases of strangulated hernia is still debated due to the potential risk of infection.ObjectiveThis systematic review aimed to determine whether or not the mesh repair technique is associated with a higher risk of surgical site infection than non‐mesh techniques for strangulated inguinal hernias in adults.MethodsAn electronic search of the relevant literature was performed on 15 December 2012 using the following databases: MEDLINE, the Cochrane Library, Scopus, Embase, and the Web of Science. Articles reporting a comparison between the mesh repair technique and a non‐mesh technique to treat strangulated inguinal hernias in adults, and published in the English or French language in a peer‐reviewed journal, were considered for analysis. The quality of randomized controlled trials (RCTs) was assessed using the Jadad scoring system. To assess the quality of non‐randomized trials, we used the Methodological Index for Non‐Randomized Studies (MINORS).ResultsA total of 232 papers was found in the initial search; nine were included in the meta‐analysis. The wound infection rate in the mesh repair technique group was lower than in the control group, with a trend towards significance (odds ratio [OR] 0.46, 95 % confidence interval [CI] 0.20–1.07; p = 0.07). The hernia recurrence rate was lower in the mesh repair group (OR 0.2, 95 % CI 0.05–0.78; p = 0.02).ConclusionThe mesh repair technique is a good option for the treatment of strangulated inguinal hernias in adults, giving an acceptable wound infection rate and fewer recurrences than non‐mesh repair. Our study does not allow us to recommend the use of mesh in cases of bowel resection. We emphasize that, except the two RCTs, the results are predicated on patient selection bias by careful surgeons. Further RCTs are required to obtain more powerful evidence‐based data.
Characterization of type III TGF‐β receptor expression in invasive breast carcinomas: a potential new marker and target for triple negative breast cancer

Published: August 2014

AbstractInvasive breast carcinomas are heterogeneous and exhibit distinct molecular features and biological behavior. Understanding the underlying molecular events that promote breast cancer progression is necessary to improve treatment and prognostication. TGF‐β receptor III (TBR3) is a member of the TGF‐β signaling pathway, with functions in cell proliferation and migration in malignancies, including breast cancer. Recent studies propose that TBR3 may function as a tumor suppressor and that its loss may correlate with disease progression. However, there are limited data on the expression of TBR3 in breast cancer in relationship to tumor type, hormonal receptor status and HER‐2/neu, and patient outcome. In this study, we investigated the expression of TBR3 in a cohort of 205 primary invasive breast carcinomas in tissue microarrays (TMAs), with comprehensive clinical, pathological and follow‐ up information. Sections were stained for TBR3 and evaluated for intensity of reactivity based on a 4‐tiered scoring system (1 to 4; TBR3 low = scores 1–2; TBR3 high = scores 3–4). Of the 205 invasive carcinomas, 123 were luminal type (95 type A, 28 type B), 8 were HER‐2 type, and 62 were triple negative (TN). TBR3 was high in 112 (55 %) and low in 93 (45 %) cases. Low TBR3 was associated with higher histological grade and worse disease free and overall survival, all features of biologically aggressive breast carcinomas. TBR3 was significantly associated with the subtype of breast cancer, as low TBR3 was detected in 95 % of TN compared to 22 % of luminal tumors (p < 0.0001). We discovered a significant association between low TBR3 protein expression, TN breast cancer phenotype, and disease progression. These data suggest that TBR3 loss might be linked to the development of TN breast cancers and pave the way to investigating whether restoring TBR3 function may be a therapeutic strategy against TN breast carcinomas.
The Politics of New African Marriage in Segregationist South Africa
Authors: Healy-Clancy Meghan 
Published: August 2014

Abstract:For the mission-educated men and women known as “New Africans” in segregationist South Africa, the pleasures and challenges of courtship and marriage were not only experienced privately. New Africans also broadcast marital narratives as political discourses of race-making and nation-building. Through close readings of neglected press sources and memoirs, this article examines this political interpolation of private life in public culture. Women’s writing about the politics of marriage provides a lens onto theorizations of their personal and political ideals in the 1930s and 1940s, a period in which the role of women in nationalist public culture has generally been dismissed as marginal by scholars.
Queer Agency in Kenya’s Digital Media
Authors: Mwangi Evan 
Published: August 2014

Abstract:Although scholars have noted the rising potentials for democracy in Africa as a result of increased use of digital media and mobile technologies, there seems to be a disregard or disavowal of queerness as part of that growing democratic space, as well as a related tendency to regard African culture solely in terms of mainstream writing and journalism. This article seeks to bridge this gap in the scholarship by means of a discourse analysis of comments about queer identities that can be found in the digital media (Facebook, chat rooms, blogs, YouTube comments, and online newspaper feedback) in contemporary Kenya. Following work on queer arts and “low” theory, the article explores the possibilities offered by the Internet to challenge homophobia in Kenya. While acknowledging that digital-media venues contain more homophobia than mainstream media (books, television, newspapers) in terms of intensity and quantity, the article demonstrates that they also offer a unique platform in which gay people can respond to homophobic representations of their experiences and desires.
ON REGULAR GROUPS AND FIELDS
Authors: GOGACZ TOMASZ , KRUPIŃSKI KRZYSZTOF 
Published: August 2014

AbstractRegular groups and fields are common generalizations of minimal and quasi-minimal groups and fields, so the conjectures that minimal or quasi-minimal fields are algebraically closed have their common generalization to the conjecture that each regular field is algebraically closed. Standard arguments show that a generically stable regular field is algebraically closed. LetKbe a regular field which is not generically stable and letpbe its global generic type. We observe that ifKhas a finite extensionLof degreen, thenP(n)has unbounded orbit under the action of the multiplicative group ofL.Known to be true in the minimal context, it remains wide open whether regular, or even quasi-minimal, groups are abelian. We show that if it is not the case, then there is a counter-example with a unique nontrivial conjugacy class, and we notice that a classical group with one nontrivial conjugacy class is not quasi-minimal, because the centralizers of all elements are uncountable. Then, we construct a group of cardinality ω1with only one nontrivial conjugacy class and such that the centralizers of all nontrivial elements are countable.
DIOPHANTINE SETS OF POLYNOMIALS OVER ALGEBRAIC EXTENSIONS OF THE RATIONALS
Authors: DEGROOTE CLAUDIA , DEMEYER JEROEN 
Published: August 2014

AbstractLet L be a recursive algebraic extension of ℚ. Assume that, given α ∈ L, we can compute the roots in L of its minimal polynomial over ℚ and we can determine which roots are Aut(L)-conjugate to α. We prove that there exists a pair of polynomials that characterizes the Aut(L)-conjugates of α, and that these polynomials can be effectively computed. Assume furthermore that L can be embedded in ℝ, or in a finite extension of ℚp (with p an odd prime). Then we show that subsets of L[X]k that are recursively enumerable for every recursive presentation of L[X], are diophantine over L[X].
ONE DIMENSIONAL T.T.T STRUCTURES
Authors: LOWENGRUB DANIEL 
Published: August 2014

AbstractIn this paper we analyze the relationship between o-minimal structures and the notion of ω-saturated one-dimensional t.t.t structures. We prove that if removing any point from such a structure splits it into more than one definably connected component then it must be a one-dimensional simplex of a finite number of o-minimal structures. In addition, we show that even if removing points doesn’t split the structure, additional topological assumptions ensure that the structure is locally o-minimal. As a corollary we obtain the result that if an ω-saturated one-dimensional t.t.t structure admits a topological group structure then it is locally o-minimal. We also prove that the number of connected components in a definable family is uniformly bounded, which implies that an elementary extension of an ω-saturated one-dimensional t.t.t structure is t.t.t as well.
MODEL THEORETIC PROPERTIES OF METRIC VALUED FIELDS
Authors: YAACOV ITAÏ BEN 
Published: August 2014

We study model theoretic properties of valued fields (equipped with a real-valued multiplicative valuation), viewed as metric structures in continuous first order logic.For technical reasons we prefer to consider not the valued field (K, |·|) directly, but rather the associated projective spaces KPn, as bounded metric structures.We show that the class of (projective spaces over) metric valued fields is elementary, with theory MVF, and that the projective spaces Pn and are Pm biinterpretable for every n, m ≥ 1. The theory MVF admits a model completion ACMVF, the theory of algebraically closed metric valued fields (with a nontrivial valuation). This theory is strictly stable (even up to perturbation).Similarly, we show that the theory of real closed metric valued fields, RCMVF, is the model companion of the theory of formally real metric valued fields, and that it is dependent.
RELATIVE PREDICATIVITY AND DEPENDENT RECURSION IN SECOND-ORDER SET THEORY AND HIGHER-ORDER THEORIES
Authors: KENTARO SATO 
Published: August 2014

AbstractThis article reports that some robustness of the notions of predicativity and of autonomous progression is broken down if as the given infinite total entity we choose some mathematical entities other than the traditionalω. Namely, the equivalence between normal transfinite recursion scheme and newdependent transfinite recursionscheme, which does hold in the context of subsystems of second order number theory, does not hold in the context of subsystems of second order set theory where the universeVof sets is treated as the given totality (nor in the contexts of those ofn+3-th order number or set theories, where the class of alln+2-th order objects is treated as the given totality).
Gender equality in African customary law: has the male ultimogeniture rule any future in Botswana?
Authors: Fombad Charles Manga 
Published: August 2014

ABSTRACTThe actual and perceived conflicts between customary law and human rights law, especially in issues dealing with gender equality, have remained a major challenge in Africa. Some of these conflicts are further complicated by the varying and contradictory interpretation of some customary laws by the courts. Different approaches have been adopted at different times and in different places to deal with some of these conflicts. One of the most controversial areas of customary law has been the traditional exclusion of women from property inheritance. This paper takes a critical look at how the courts in Botswana have dealt with the issue of the right to inherit the homestead or family home. It examines this issue in the specific context of the recent case of Ramantele v Mmusi in which the Court of Appeal had to consider the customary law rule of male ultimogeniture – which permits only the last-born son to inherit the homestead intestate to the exclusion of other siblings, especially females. It argues that courts need to be more proactive and progressive in their approach to dealing with such issues than they have been in the past in order to recognise the nature and extent of changes that are taking place today. The main lesson that can be drawn from the Botswana case is that if customary law is to survive and develop, more needs to be done to promote research and scholarship in this area and judges also need to take advantage of this research and deal with these customary law disputes with knowledge, understanding and sensitivity.
An extended Arctic proxy temperature database for the past 2,000 years
Authors: McKay Nicholas P. , Kaufman Darrell S. 
Published: August 2014

AbstractRobust climate reconstructions of the most recent centuries and millennia are invaluable for placing modern warming in the context of natural variability. Here we present an extended and revised database (version 1.1) of proxy temperature records recently used to reconstruct Arctic temperatures for the past 2,000 years. The datasets are presented in a machine-readable format, and have been extended with the geochronologic data and consistently generated time-uncertain ensembles, which will be useful in future analyses of the influence of geochronologic uncertainty. A standardized description of the seasonality of the temperature response for each record, as reported by the original authors, is also included to motivate a more nuanced approach to integrating records with variable seasonal sensitivities. Despite the predominance of seasonal, rather than annual, temperature responders in the database, comparisons with the instrumental record of temperature suggest that, as a whole, the datasets best record annual temperature variability across the Arctic, especially in northeast Canada and Greenland, where the density of records is highest.
Direct Observation of Coherent Oscillations in Solution due to Microheterogeneous Environment

Published: August 2014

AbstractWe report, for the first time, direct observation of coherent oscillations in the ground-state of IR775 dye due to microheterogeneous environment. Using ultrafast near-infrared degenerate pump-probe technique centered at 800 nm, we present the dynamics of IR775 in a binary mixture of methanol and chloroform at ultra-short time resolution of 30 fs. The dynamics of the dye in binary mixtures, in a time-scale of a few fs to ~740 ps, strongly varies as a function of solvent composition (volume fraction). Multi-oscillation behavior of the coherent vibration was observed, which increased with decreasing percentage of methanol in the dye mixture. Maximum number of damped oscillations were observed in 20% methanol. The observed vibrational wavepacket motion in the ground-state is periodic in nature. We needed two cosine functions to fit the coherent oscillation data as two different solvents were used. Dynamics of the dye molecule in binary mixtures can be explained by wavepacket motion in the ground potential energy surface. More is the confinement of the dye molecule in binary mixtures, more is the number of damped oscillations. The vibrational cooling time, τ2, increases with increase in the confinement of the system. The observed wavepacket oscillations in ground-state dynamics continued until 1.6 ps.
The significance of p40 expression in sclerosing hemangioma of lung
Authors: Wu Jian , Zhang Chang , Qiao Haiguo 
Published: August 2014

AbstractTo explore the histogenesis of cuboidal and polygonal tumor cells in the sclerosing hemangioma of lung (SHL), eighteen cases of SHL were retrospectively studied. SPB, p40, TTF-1,EMA,CKpan, vimentin,SMA, CgA,Syn and CD34 were immunohistochemically labeled by the EnVisionmethod. It was found that the four main types of structure in SHL were solid,papillary, hemorrhagic and sclerotic patterns. The tumor cells were composed mainly of two types of cells: cuboidal tumor cells and polygonal tumor cells. The immunohistochemistry showed that p40 was expressed only in cuboidal tumor cells. TTF-1 and EMA were expressed in both polygonal cells and cuboidal cells. SPB was also expressed in cuboidal tumor cells; vimentin was expressed in all polygonal tumor cells and some cuboidal cells. The findings suggest that the p40-positive cuboidal tumor cells may be pluripotent original respiratory epithelial cells, with multi-directional differentiation capacity.

Published: August 2014

Issue addressedFood insecurity is recognised as an increasing problem in disadvantaged and marginalised groups. The aim of this study was to investigate issues associated with food insecurity and nutrition in young people experiencing, or at risk of, homelessness in metropolitan Australia.MethodsEight focus group discussions were conducted with 48 young people (aged between 15 and 25 years) in specialist homelessness services in central and south‐western Sydney.ResultsParticipants described daily experiences of food insecurity, persistent hunger and poverty. Structural barriers to food security and nutrition were identified and included poverty and reduced physical access to fresh foods. Participants also described a desire to save time, for convenience and to be socially connected. Despite the hardships and the chaos of youth homelessness, the groups were defined by their strength of character, resilience and hope for the future.ConclusionHomeless young people within central and south‐western Sydney report varying degrees of food insecurity, despite being supported by specialist youth homelessness services.So what?A collaborative, multistrategic approach with youth participation is required to further enhance the capacity of youth services to improve food security, food access and the availability of nutritious foods for homeless young people. A greater focus on advocacy and policy action is also required to bring food security and nutrition to the forefront of national efforts to improve the health and welfare of disadvantaged groups.
Conformation-specific antibodies to target amyloid β oligomers and their application to immunotherapy for Alzheimer’s disease
Authors: Murakami Kazuma 
Published: August 2014

Abstract
Amyloid β-protein (Aβ) oligomers, intermediates of Aβ aggregation, cause cognitive impairment and synaptotoxicity in the pathogenesis of Alzheimer’s disease (AD). Immunotherapy using anti-Aβ antibody is one of the most promising approaches for AD treatment. However, most clinical trials using conventional sequence-specific antibodies have proceeded with difficulty. This is probably due to the unintended removal of the non-pathological monomer and fibrils of Aβ as well as the pathological oligomers by these antibodies that recognize Aβ sequence, which is not involved in synaptotoxicity. Several efforts have been made recently to develop conformation-specific antibodies that target the tertiary structure of Aβ oligomers. Here, we review the recent findings of Aβ oligomers and anti-Aβ antibodies including our own, and discuss their potential as therapeutic and diagnostic tools.

Authors: Pan Wanbin , Wang Yigang , Du Peng 
Published: August 2014

Purpose
– The purpose of this paper is to develop an automatic disassembly navigation approach for human interactions in the virtual environment to achieve accurate and effective virtual assembly path planning (VAPP).

Design/methodology/approach
– First, to avoid the error-prone human interactions, a constraint-based disassembly method is presented. Second, to automatically provide the next operable part(s), a disassembly navigation mechanism is adopted. Finally, the accurate assembly path planning can be obtained effectively and automatically by inversing the ordered accurate disassembly paths, which are obtained interactively in the virtual environment aided with the disassembly navigation matrix.

Findings
– The applications present that our approach can effectively avoid the error-prone interactive results and generate accurate and effective VAPP.

Research limitations/implications
– There are several works that could be conducted to make our approach more general in the future: to further study the basic disassembly direction deducing rules to make the process of determining disassembly direction totally automatic, to consider the hierarchy of the parts in virtual reality system and to consider the space for assembly/disassembly tools or operators.

Originality/value
– The approach has the following characteristics: a new approach to avoid the error-prone human interactions for accurate assembly path planning obtaining, a new constraint deducing method for determining the disassembly semantics automatically or semi-automatically is put forward and a new method for automatically identifying operable parts in VAPP is set forward.
