Robust structure from motion with affine camera via low-rank matrix recovery
Authors: Wu Lun , Wang YongTian , Liu Yue , Wang YuXi 
Published: January 2013

Abstract
We present a novel approach to structure from motion that can deal with missing data and outliers with an affine camera. We model the corruptions as sparse error. Therefore the structure from motion problem is reduced to the problem of recovering a low-rank matrix from corrupted observations. We first decompose the matrix of trajectories of features into low-rank and sparse components by nuclear-norm and ℓ
1-norm minimization, and then obtain the motion and structure from the low-rank components by the classical factorization method. Unlike pervious methods, which have some drawbacks such as depending on the initial value selection and being sensitive to the large magnitude errors, our method uses a convex optimization technique that is guaranteed to recover the low-rank matrix from highly corrupted and incomplete observations. Experimental results demonstrate that the proposed approach is more efficient and robust to large-scale outliers.
The Range of Movement of the Thumb
Authors: Barakat M. J. , Field J. , Taylor J. 
Published: January 2013

Purpose The movements at each thumb joint are flexion and extension (called radial abduction in the CMCJ) and additional movements of anteposition, retroposition and opposition at the CMCJ, due to the saddle shape of the articulation. Our study was designed to provide a means of thumb movement measurement and provide a range for each. Methods A prospective cohort study was performed looking at 100 consecutive individuals without thumb pathology to determine thumb joint range of movements and evaluate the reliability of such measurements. Results The mean age was 26 (range of 18–37) with 62 female individuals. The mean range of movement of the IPJ was flexion of 88 ° (80–90 °) and extension of 12° (0–45°). That of the MCPJ was flexion of 60° (43–70°) and extension of 8.1° (0–15°). That of the CMCJ was anteposition of 61.2° (50–71°), retroposition of 31.1 mm (25–38 mm), radial abduction of 62.9° (53–71°), opposition Kapandji grade 9 (grades 9–10) and adduction of 10.2 ± 4°(5–20°). CMC adduction was difficult to measure with a poor intra- and inter-observer correlation (inter-reliability correlation coefficient of 0.02 and intra-reliability coefficient of 0.04). For the remaining measurements, the mean inter-reliability correlation coefficient was 0.82 ( p<0.01) while the mean intra-reliability correlation coefficient was 0.93 ( p<0.01). There was negative correlation identified between IPJ extension and MCPJ extension (−0.50) and between CMCJ radial abduction and MCPJ extension (−0.60). Conclusions Having established the normal ranges of movements for the thumb joints and shown that our measurement methods are reliable and reproducible, we have identified that a reduction in certain thumb joint movements appears to be compensated for by an increased movement range in the other joints.
trans‐10,cis‐12 Conjugated Linoleic Acid Improved Growth Performance, Reduced Lipid Deposition and Influenced CPT I Kinetic Constants of Juvenile Synechogobius hasta

Published: January 2013

Abstracttrans‐10,cis‐12 (t10c12) Conjugated linoleic acid (CLA) reduced body lipid deposition in various experimental animals, but the mechanisms involved were still emerging. Carnitine palmitoyltransferase I (CPT I) catalyzes an important regulatory step in lipid metabolism. At present, no studies, to our knowledge, have evaluated the kinetic constants influenced by dietary CLA in fish. In the present study, we tested the hypothesis that changes in body lipid content in fish as a response to dietary t10c12 CLA was related to the change of CPT I kinetic constants [Michaelis constant (Km), maximal velocity and catalytic efficiency for carnitine and palmitoyl‐CoA]. Juvenile Synechogobius hasta were fed three experimental diets with fish oil replaced with 0 (control), 1, or 2 % t10c12 CLA for 8 weeks. Weight gain, specific growth rate and protein efficiency rate increased with dietary t10c12 CLA level. Dietary t10c12 CLA addition significantly reduced lipid contents both in liver and muscle. Dietary CLA addition also improved CPT I activities in muscle but did not significantly influence hepatic CPT I activity. CPT I kinetic parameters (Km, Vmax and catalytic efficiency) were significantly influenced by t10c12 CLA. CPT I catalytic efficiencies with carnitine and palmitoyl‐CoA as substrates were higher in muscle and liver of fish fed increasing t10c12 CLA. For the first time, the findings demonstrated effect of dietary CLA addition on CPT I kinetics in fish and supported our starting hypothesis that dietary t10c12 CLA addition induced alterations in CPT I kinetic constants of muscle and liver. Increased CPT I catalytic efficiency might be the main reason for reduced lipid deposition in these tissues by dietary t10c12 CLA supplementation.
Does Culture Affect Divorce? Evidence From European Immigrants in the United States
Authors: Furtado Delia , Marcén Miriam , Sevilla Almudena 
Published: January 2013

Abstract
This article explores the role of culture in determining divorce by examining country-of-origin differences in divorce rates of immigrants in the United States. Because childhood-arriving immigrants are all exposed to a common set of U.S. laws and institutions, we interpret relationships between their divorce tendencies and home-country divorce rates as evidence of the effect of culture. Our results are robust to controlling for several home-country variables, including average church attendance and gross domestic product (GDP). Moreover, specifications with country-of-origin fixed effects suggest that immigrants from countries with low divorce rates are especially less likely to be divorced if they reside among a large number of coethnics. Supplemental analyses indicate that divorce culture has a stronger impact on the divorce decisions of females than of males, pointing to a potentially gendered nature of divorce taboos.
Skewed Sex Ratios in India: “Physician, Heal Thyself”

Published: January 2013

Abstract
Sex selection, a gender discrimination of the worst kind, is highly prevalent across all strata of Indian society. Physicians have a crucial role in this practice and implementation of the Indian Government’s Pre-Natal Diagnostic Techniques Act in 1996 to prevent the misuse of ultrasound techniques for the purpose of prenatal sex determination. Little is known about family preferences, let alone preferences among families of physicians. We investigated the sex ratios in 946 nuclear families with 1,624 children, for which either one or both parents were physicians. The overall child sex ratio was more skewed than the national average of 914. The conditional sex ratios decreased with increasing number of previous female births, and a previous birth of a daughter in the family was associated with a 38 % reduced likelihood of a subsequent female birth. The heavily skewed sex ratios in the families of physicians are indicative of a deeply rooted social malady that could pose a critical challenge in correcting the sex ratios in India.
An Abramov formula for stationary spaces of discrete groups
Authors: HARTMAN YAIR , LIMA YURI , TAMUZ OMER 
Published: January 2013

AbstractLet $(G, \mu )$ be a discrete group equipped with a generating probability measure, and let $\Gamma $ be a finite index subgroup of $G$. A $\mu $-random walk on $G$, starting from the identity, returns to $\Gamma $ with probability one. Let $\theta $ be the hitting measure, or the distribution of the position in which the random walk first hits $\Gamma $. We prove that the Furstenberg entropy of a $(G, \mu )$-stationary space, with respect to the action of $(\Gamma , \theta )$, is equal to the Furstenberg entropy with respect to the action of $(G, \mu )$, times the index of $\Gamma $ in $G$. The index is shown to be equal to the expected return time to $\Gamma $. As a corollary, when applied to the Furstenberg–Poisson boundary of $(G, \mu )$, we prove that the random walk entropy of $(\Gamma , \theta )$ is equal to the random walk entropy of $(G, \mu )$, times the index of $\Gamma $ in $G$.
The first aglaspidid sensu stricto from the Cambrian of China (Sandu Formation, Guangxi)
Authors: LEROSEY-AUBRIL RUDY , ORTEGA-HERNÁNDEZ JAVIER , ZHU XUEJIAN 
Published: January 2013

AbstractAglaspidids represent an obscure group of lower Palaeozoic arthropods with a patchy biogeographic distribution. Before the recent description of a representative from Tasmania, these arthropods were exclusively known from Laurentia during the late Cambrian. Here we describe a new species, Aglaspella sanduensis sp. nov., from the Furongian of China, confirming that aglaspidids sensu stricto were already widely distributed worldwide by the late Cambrian; this demonstrates that some aglaspidids had great dispersal capabilities. A new diagnosis of the genus Aglaspella is proposed and the species formerly known as Aglaspella eatoni is assigned to a new taxon, Hesselbonia gen. nov.

Published: January 2013

AbstractBackground:Ceruminous mucoepidermoid carcinoma of the external auditory canal is extremely rare. This paper highlights the impact of concurrent chemoradiotherapy on the outcomes of this disease.Case report:A 47-year-old female presented with a 2-month history of otalgia and a mass in her right ear. Biopsy revealed high grade ceruminous mucoepidermoid carcinoma. She underwent surgical excision of the right external auditory canal and right upper neck dissection. Pathological analysis of tumour–node–metastasis staging revealed a T2 N0 (stage II) tumour. One year later, computed tomography scanning of the temporal bone showed tumour recurrence. Biopsy revealed recurrent ceruminous mucoepidermoid carcinoma. The patient underwent salvage resection. Pathology revealed that the tumour was diffusely invading nearby structures, with perineural invasion, lymphatic spread and extracapsular extension. Pathological analysis of tumour–node–metastasis staging revealed a T3 N1 M0 (recurrent stage IV) tumour.Results:The patient subsequently received concurrent chemoradiotherapy. There was no evidence of disease at 37 months' follow up.Conclusion:The trimodality approach, using surgery plus concurrent chemoradiotherapy, provided reasonable loco-regional control with tolerable toxicity. Further detailed case reports are warranted to optimise the management of this rare malignancy.

Published: January 2013

AbstractObjective:Proteases of the disintegrin and metalloproteinase family (also known as ADAM proteins) are involved in various physiological and pathological processes. This study assessed the expression of disintegrin and metalloproteinase family proteins 10, 12 and 17 in cholesteatoma.Materials and methods:The study evaluated cholesteatoma specimens from 19 patients, and external ear canal skin samples from 7 of the same patients (as controls), for the expression of disintegrin and metalloproteinase family proteins 10, 12 and 17, using immunohistochemical methods.Results and analysis:The study observed over-expression of proteins 10 and 17 in blood vessels, and over-expression of proteins 12 and 17 in cholesteatoma stroma. Immunostaining scores for proteins 10, 12 and 17 in epithelial and inflammatory cells from cholesteatoma specimens versus control specimens showed no statistically significant differences.Conclusion:Over-expression of disintegrin and metalloproteinase family proteins 10, 12 and 17 in cholesteatoma may be related to cholesteatoma pathogenesis. These proteins deserve further study as they may represent potential targets for cholesteatoma treatment.
The Ambivalence and Lust of Marriage: With and Beyond Augustine Towards a Theology of Marriage as Consecrated Sacrifice
Authors: Ellis Daryl 
Published: January 2013

AbstractThis article argues that the Christian West's indebtedness to contractual logic in regard to marriage, as canonically depicted in 1 Corinthians 7, has resulted in a corresponding theological and pastoral myopia. The weakness of this reliance, as seen paradigmatically in Augustine's theology of marriage, consists in its articulation of marriage's constitution apart from any meaningful reference to the particular dynamics of any given marital common life. ‘Marriage’, in this sense, remains extrinsic to the living of marriage. Augustine doubly solidifies this separation by construing marriage as a contractually negotiated site for the sinful, though forgivable, expression of sexual desire, which he then roots in a christological account of sacrament whereby the sacramental bond of marriage canneverbe broken regardless of the lived particularities of marital life. A promising corrective can be found by way of a theological retrieval of a minor set of images suggestively employed in passages such as Ephesians 5:21–33 and Revelation 19:7–9 rooted in cultic themes such as sacrifice and consecration, which Augustine employs in describing marriage's preferred ecclesial alternative: the consecration of virginity. The constructive result is a theology of marriage in which every moment of marital life is marked by the ambivalence of vulnerably and ‘deathly’ surrendering to one another, which is pre-eminently embodied in the surrender of Christ himself upon the cross to the one he called Father. This ambivalence is characterised by the dual possibility, inherent in the posture of surrender itself, in which the result can either bear the healing fruits of love and reciprocal embraceorthe tragic inhumanity of abuse, rejection and manipulation. Finally, the sacrificial and contractual elements of marriage might be ultimately reconciled in a refigured notion of ‘covenant’, which too often has been understood simply as a synonym for ‘contract’. Instead, a proper covenantal understanding of marriage emerges as a participatory analogy to the entire, complicated and contingent history of God, with God's people marked by seemingly endless cycles of sin, repentance, forgiveness and restoration. Intriguingly, this history was also founded within a temporal space outlined by a mix of contractual elements and cultic regulations. Likewise, the covenantal founding of a marriage mirrors a similar dynamic: the initial ‘contractual’ vows speak into existence a temporalised space within which a daily, mundane life of lovemightcome to pass and bear its fruits, in due time, by God's grace and the daily improvisations of love and sacrifice.
Developing a computational model to understand the contributions of social learning modes to task coordination in teams

Published: January 2013

AbstractThis paper reports on a computational model developed to study the effects of various modes of social learning on task coordination in teams through the mapping of distributed team competence, a significant aspect of efficient teamwork. The computational model emphasizes and operationalizes distinct modes of social learning, differentiated in terms of socialization opportunities. Simulation results demonstrate that computational models based on fundamental principles of social learning provide a robust approach to study task coordination in teams and can be used to explore ways to organize opportunities for social learning depending upon member retention, team structure, and the complexity of the design task.
A semantic space approach to the computational semantics of noun compounds
Authors: UTSUMI AKIRA 
Published: January 2013

AbstractThis study examines the ability of a semantic space model to represent the meaning of noun compounds such as ‘information gathering’ or ‘heart disease.’ For a semantic space model to compute the meaning and the attributional similarity (or semantic relatedness) for unfamiliar noun compounds that do not occur in a corpus, the vector for a noun compound must be computed from the vectors of its constituent words using vector composition algorithms. Six composition algorithms (i.e., centroid, multiplication, circular convolution, predication, comparison, and dilation) are compared in terms of the quality of the computation of the attributional similarity for English and Japanese noun compounds. To evaluate the performance of the computation of the similarity, this study uses three tasks (i.e., related word ranking, similarity correlation, and semantic classification), and two types of semantic spaces (i.e., latent semantic analysis-based and positive pointwise mutual information-based spaces). The result of these tasks is that the dilation algorithm is generally most effective in computing the similarity of noun compounds, while the multiplication algorithm is best suited specifically for the positive pointwise mutual information-based space. In addition, the comparison algorithm works better for unfamiliar noun compounds that do not occur in the corpus. These findings indicate that in general a semantic space model, and in particular the dilation, multiplication, and comparison algorithms have sufficient ability to compute the attributional similarity for noun compounds.

AbstractObjectiveTo evaluate five popular fast-food chains’ menus in relation to dietary guidance.DesignMenus posted on chains’ websites were coded using the Food and Nutrient Database for Dietary Studies and MyPyramid Equivalents Database to enable Healthy Eating Index-2005 (HEI-2005) scores to be assigned. Dollar or value and kids’ menus and sets of items promoted as healthy or nutritious were also assessed.SettingFive popular fast-food chains in the USA.SubjectsNot applicable.ResultsFull menus scored lower than 50 out of 100 possible points on the HEI-2005. Scores for Total Fruit, Whole Grains and Sodium were particularly dismal. Compared with full menus, scores on dollar or value menus were 3 points higher on average, whereas kids’ menus scored 10 points higher on average. Three chains marketed subsets of items as healthy or nutritious; these scored 17 points higher on average compared with the full menus. No menu or subset of menu items received a score higher than 72 out of 100 points.ConclusionsThe poor quality of fast-food menus is a concern in light of increasing away-from-home eating, aggressive marketing to children and minorities, and the tendency for fast-food restaurants to be located in low-income and minority areas. The addition of fruits, vegetables and legumes; replacement of refined with whole grains; and reformulation of offerings high in sodium, solid fats and added sugars are potential strategies to improve fast-food offerings. The HEI may be a useful metric for ongoing monitoring of fast-food menus.

Published: January 2013

Introduction Mandibular angle fractures can be treated by various methods, but even the most popular methods may not be able to give satisfactory results, as the pterygomasseteric sling and masticatory forces can result in displaced angle fracture. These displaced fragments cannot be satisfactorily retained by single miniplate fixation. The aim of this study is to assess treatment of displaced angle fracture with 3-D miniplate fixation. This study can also be considered as a therapeutic study with level V evidence. Materials and Methods This study was designed to assess the feasibility of 3-D matrix miniplate fixation in displaced angle fractures. Eighteen patients with displaced angle fractures were included in this study. Matrix miniplate fixation was done transorally under general anesthesia. Results All these cases were treated successfully, and common complications like infection (5.5% of patients), wound dehiscence (11%), paresthesia (16.7%), and malocclusion (11%) were observed in our study. Conclusions Three-dimensional miniplate fixation in displaced angle fractures provides better stability and function.

We have prepared mixed phthalocyanine films out of MnPc and F16CoPc, which were characterized by means of photoemission spectroscopy and electron energy-loss spectroscopy. Our data reveal the formation of MnPc/F16CoPc charge transfer dimers in analogy to the related heterojunction. The electronic excitation spectrum of these blends is characterized by a new low energy excitation at 0.6 eV. Density functional theory calculations show that the new signal is caused by a strong absorption between the states of the interface induced two level system.

Significance
Early signaling events leading to protection in the heart under cardiac injury are poorly understood. We identified one such protein, A kinase interacting protein (AKIP1), as a modulator that responds to oxidative stress; up-regulation of AKIP1 showed protection to ischemic injury through enhanced mitochondrial integrity. We show AKIP1 functions as a molecular scaffold via interaction with mitochondrial apoptosis inducing factor and increases protein kinase A activity. These mitochondrial signaling complexes assembled by AKIP1 alter the physiological response of the heart under ischemic stress. Understanding molecular activity and regulation of AKIP1 could lead to novel therapeutic approaches to limit myocardial injury.
