Published: January 2018

Feature selection has been an important issue in machine learning and data mining, and is unavoidable when confronting with high‐dimensional data. With the advent of multilabel (ML) datasets and their vast applications, feature selection methods have been developed for dimensionality reduction and improvement of the classification performance. In this work, we provide a comprehensive review of the existing multilabel feature selection (ML‐FS) methods, and categorize these methods based on different perspectives. As feature selection and data classification are closely related to each other, we provide a review on ML learning algorithms as well. Also, to facilitate research in this field, a section is provided for setup and benchmarking that presents evaluation measures, standard datasets, and existing software for ML data. At the end of this survey, we discuss some challenges and open problems in this field that can be pursued by researchers in future.

AbstractBackgroundAmbulatory surgery for anorectal procedures has been proven to be safe and effective. Specific perioperative pathways combining multiple interventions have been shown to optimize recovery and outcomes associated with inpatient colorectal surgery. However, there are no major studies describing and evaluating a standardized protocol for ambulatory anorectal surgery. The purpose of this study was to evaluate the outcomes of a modified enhanced recovery after surgery (ERAS) protocol for ambulatory anorectal surgery.MethodsThis was a retrospective review of prospectively collected data from 14 Southern California Kaiser Permanente medical centers. An eight‐item protocol including: preoperative education, preoperative distribution of prescriptions, preoperative carbohydrate treatment, multimodal analgesia, preferential use of monitored anesthesia care (MAC), routine use of local anesthesia/regional blocks, intraoperative restriction of intravenous fluids, and post‐discharge phone call. Postoperative pain scores and preventable returns to the emergency department or urgent care were assessed.ResultsPostoperative pain scores were reduced when all eight elements of the protocol were delivered (p = 0.005). On multivariate analysis, there was reduced postoperative pain when preoperative carbohydrate treatment was completed (p = 0.002), with MAC (p = 0.003), and when multimodal analgesia was used (p = 0.02). There were decreased preventable returns to the emergency department or urgent care when MAC was used (p = 0.03); there were more returns for constipation (p = 0.04) but fewer returns for pain (p = 0.002) after preoperative carbohydrate treatment. Local anesthesia was associated with fewer returns for constipation (p = 0.01).ConclusionsImplementation of a standardized ERAS protocol for ambulatory anorectal surgery decreased postoperative pain and unplanned return visits to emergency care.

Published: January 2018

AbstractIntroductionIn looking for novel non‐amyloid‐based etiologies for Alzheimer's disease, we explore the hypothesis that age‐related myelin loss is an attractive explanation for age‐associated cognitive decline and dementia.MethodsWe performed a meta‐analysis of data in the National Alzheimer's Coordinating Center database accompanied by quantitative histopathology of myelin and oligodendrocytes (OLs) in frontal cortices of 24 clinically characterized individuals. Pathological findings were further validated in an Alzheimer's disease mouse model and in culture.ResultsMyelin lesions increased with cognitive impairment in an amyloid‐independent fashion with signs of degeneration appearing before neuronal loss. Myelinating OLs in the gray matter showed greater vulnerability than those in white matter, and the degenerative changes correlated with evidence of DNA damage. Similar results were found in myelinating OL cultures where DNA damage caused aberrant OL cell cycle re‐entry and death.DiscussionWe present the first comprehensive analysis of the cell biology of early myelin loss in sporadic Alzheimer's disease.

ResumoComparar o tempo médio de retorno dos atletas ao esporte após lesão muscular aguda da coxa com hematoma que foi ou não puncionado.Estudo longitudinal de intervenção clínica, controlado e não randomizado, com participação de 20 atletas amadores e profissionais com lesão muscular aguda do tipo parcial moderada ou (sub)total na região da coxa, segundo a classificação do Consenso de Munique. Nove atletas foram incluídos no grupo intervenção e 11 no grupo controle. Os atletas do grupo intervenção foram submetidos a punção do hematoma e fisioterapia e os do grupo controle, apenas a fisioterapia. A variável tempo de retorno ao esporte foi analisada com o teste de Mann-Whitney e o nível de significância usado foi 95% (p < 0,05).A população estudada foi composta principalmente por homens, dos quais oito eram praticantes de esportes no nível amador. Três mulheres, das quais duas eram amadoras, foram incluídas no estudo. A média de idade dos participantes foi de 34,70 ± 12,79 anos. Houve 13 indivíduos com lesões na região posterior da coxa, cinco com lesões na região anterior e dois com lesões na região adutora. Considerando todas as lesões, o tempo médio de retorno ao esporte foi de 48,50 ± 27,50 dias no grupo intervenção. Já no grupo controle, esse intervalo foi de 102,09 ± 52,02 dias (p = 0,022).No presente estudo, a punção do hematoma muscular mostrou-se efetiva em abreviar o tempo de retorno ao esporte dos atletas com lesões musculares parciais moderadas e (sub)totais associadas a hematomas.
A NEURAL-NETWORK ANALYZER FOR MORTALITY FORECAST
Authors: Hainaut Donatien 
Published: January 2018

AbstractThis article proposes a neural-network approach to predict and simulate human mortality rates. This semi-parametric model is capable to detect and duplicate non-linearities observed in the evolution of log-forces of mortality. The method proceeds in two steps. During the first stage, a neural-network-based generalization of the principal component analysis summarizes the information carried by the surface of log-mortality rates in a small number of latent factors. In the second step, these latent factors are forecast with an econometric model. The term structure of log-forces of mortality is next reconstructed by an inverse transformation. The neural analyzer is adjusted to French, UK and US mortality rates, over the period 1946–2000 and validated with data from 2001 to 2014. Numerical experiments reveal that the neural approach has an excellent predictive power, compared to the Lee–Carter model with and without cohort effects.
Topic, Focus and null subjects in Old French
Authors: Ingham Richard 
Published: January 2018

AbstractOld French subject pronouns (Spro) were omissible if postverbal (Foulet 1928), but not freely so (Vance 1997, Zimmermann 2014). This article addresses their partial omissibility in discourse-syntax terms, following work on partial null subject languages by Holmberg and Nikanne (2002) and Modesto (2008). An observational study of dialogic responses in 13th century prose romances is first reported, finding strong indications of covariation between the Topic/Focus status of an initial non-subject constituent and the expression/omission of post-verbal Spro. A quantitative investigation, in such texts, of preposed discourse-linked anaphoric constituents and preposed intensifiers, taken as diagnostic of Topichood and Focushood respectively, confirmed this analysis. We take null Spro to be available (i) when a null Topic operator targets left-peripheral TopicP, and (ii) with a left-peripheral Focused expression. When a discourse-linked non-subject constituent occupies TopicP, however, Spro must be overt.
EQUIVALENT DEFINITIONS OF SUPERSTABILITY IN TAME ABSTRACT ELEMENTARY CLASSES
Authors: GROSSBERG RAMI , VASEY SEBASTIEN 
Published: January 2018

AbstractIn the context of abstract elementary classes (AECs) with a monster model, several possible definitions of superstability have appeared in the literature. Among them are no long splitting chains, uniqueness of limit models, and solvability. Under the assumption that the class is tame and stable, we show that (asymptotically) no long splitting chains implies solvability and uniqueness of limit models implies no long splitting chains. Using known implications, we can then conclude that all the previously-mentioned definitions (and more) are equivalent:Corollary.LetKbe a tame AEC with a monster model. Assume thatKis stable in a proper class of cardinals. The following are equivalent:(1)For all high-enough λ,Khas no long splitting chains.(2)For all high-enough λ, there exists a good λ-frame on a skeleton ofKλ.(3)For all high-enough λ,Khas a unique limit model of cardinality λ.(4)For all high-enough λ,Khas a superlimit model of cardinality λ.(5)For all high-enough λ, the union of any increasing chain of λ-saturated models is λ-saturated.(6)There exists μ such that for all high-enough λ,Kis (λ,μ) -solvable.This gives evidence that there is a clear notion of superstability in the framework of tame AECs with a monster model.
ON DEFINABLE SKOLEM FUNCTIONS IN WEAKLY O-MINIMAL NONVALUATIONAL STRUCTURES

Published: January 2018

AbstractWe prove that all known examples of weakly o-minimal nonvaluational structures have no definable Skolem functions. We show, however, that such structures eliminate imaginaries up to definable families of cuts. Along the way we give some new examples of weakly o-minimal nonvaluational structures.
ON THE UNIFORM COMPUTATIONAL CONTENT OF RAMSEY’S THEOREM
Authors: BRATTKA VASCO , RAKOTONIAINA TAHINA 
Published: January 2018

AbstractWe study the uniform computational content of Ramsey’s theorem in the Weihrauch lattice. Our central results provide information on how Ramsey’s theorem behaves under product, parallelization, and jumps. From these results we can derive a number of important properties of Ramsey’s theorem. For one, the parallelization of Ramsey’s theorem for cardinalityn≥ 1 and an arbitrary finite number of colorsk≥ 2 is equivalent to then-th jump of weak Kőnig’s lemma. In particular, Ramsey’s theorem for cardinalityn≥ 1 is${\bf{\Sigma }}_{n + 2}^0$-measurable in the effective Borel hierarchy, but not${\bf{\Sigma }}_{n + 1}^0$-measurable. Secondly, we obtain interesting lower bounds, for instance then-th jump of weak Kőnig’s lemma is Weihrauch reducible to (the stable version of) Ramsey’s theorem of cardinalityn+ 2 forn≥ 2. We prove that with strictly increasing numbers of colors Ramsey’s theorem forms a strictly increasing chain in the Weihrauch lattice. Our study of jumps also shows that certain uniform variants of Ramsey’s theorem that are indistinguishable from a nonuniform perspective play an important role. For instance, the colored version of Ramsey’s theorem explicitly includes the color of the homogeneous set as output information, and the jump of this problem (but not the uncolored variant) is equivalent to the stable version of Ramsey’s theorem of the next greater cardinality. Finally, we briefly discuss the particular case of Ramsey’s theorem for pairs, and we provide some new separation techniques for problems that involve jumps in this context. In particular, we study uniform results regarding the relation of boundedness and induction problems to Ramsey’s theorem, and we show that there are some significant differences with the nonuniform situation in reverse mathematics.
Urban climate change, livelihood vulnerability and narratives of generational responsibility in Jinja, Uganda

Published: January 2018

AbstractThere is an urgent need to understand lived experiences of climate change in the context of African cities, where even small climate shocks can have significant implications for the livelihoods of the urban poor. This article examines narratives of climate and livelihood changes within Jinja Municipality, Uganda, emphasizing how Jinja's residents make sense of climate change through their own narrative frames rather than through the lens of global climate change discourses. We demonstrate how the onset of climate change in Jinja is widely attributed to perceived moral and environmental failings on the part of a present generation that is viewed as both more destructive than previous generations and unable to preserve land, trees and other resources for future generations. A focus on local ontologies of climate change highlights how the multiple, intersecting vulnerabilities of contemporary urban life in Jinja serve to obfuscate not only the conditions of possibility of an immediate future, but the longer-term horizons for future generations, as changing weather patterns exacerbate existing challenges people face in adapting to wider socio-economic changes and rising livelihood vulnerability. This form of analysis situates changing climate and environments within the context of everyday urban struggles and emphasizes the need for civic participation in developing climate change strategies that avoid the pitfalls of climate reductionism. The article draws on more than 150 qualitative interviews, generational dialogue groups, and creative methods based on research-led community theatre.
Urban development and emerging relations of informal property and land-based authority in Accra
Authors: Stacey Paul 
Published: January 2018

AbstractRural–urban migration leads to ever increasing numbers of Africans living in informal settlements. In Accra's largest informal settlement, Old Fadama, residents by definition have no statutory rights to the land and their building activities undermine formal state law and state-recognized customary landowners. Statutory institutions are unable to enforce property rights and alternative interests emerge and organize. In multiple and fragmented ways, local stakeholders create and define their own informal relations of property and land-based authority. This article examines four cases of land transfers, building and development in the settlement that involve a variety of local, national and global actors. Their actions show the contemporaneous making and unmaking of different relations of property and land-based control and authority in the densely populated urban site. Important features of urban development in Accra are thereby shown to be variations in property relations and the multitude of actors that validate land use but that circumvent statutory institutions.
Three nineteenth-century Southern African San myths: a study in meaning
Authors: Lewis-Williams J. David 
Published: January 2018

AbstractIndigenous significances of nineteenth-century |Xam San folktales are hard to determine from narrative structure alone. When verbatim, original-language records are available, meaning can be elicited by probing beneath the narrative and exploring the connotations of highly significant words and phrases that imply meanings and associations that narrators take for granted but that nonetheless contextualize the tales. Analyses of this kind show that three selected |Xam tales deal with a form of spiritual conflict that has social implications. Like numerous |Xam myths, these tales concern conflict between people and living or dead malevolent shamans. Using their supernatural potency, benign shamans transcend the levels of the San cosmos in order to deal with social conflict and to protect material resources. As a result, benign shamans enjoy a measure of respect that sets them apart from ordinary people.

AbstractNutraceuticals have generated interest as a way to mitigate the cognitive decline in older adults. The aim of this systematic review was to determine the evidence for these claims from the scientific literature in randomised, double-blinded, controlled trials (duration: ≥1 year; participants:n≥100; age(mean): ≥65 years). Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched four electronic databases (PubMed, Scopus, CINAHL and Web of Science) and identified twenty-five studies published between the 15·June·2006 and 14·June·2016. Interventions included B-vitamins,n-3 fatty acids, antioxidant vitamins and herbs. Of the B-vitamin studies, four found benefits to cognition with supplementation. The first of these B-vitamin studies, in individuals with mild cognitive impairment (n266; duration=2 years), included benefit to executive function (P=0·015) and improvements in the Mini-Mental State Examination (MMSE) among participants with baseline homocysteine above 11·3 µmol/l (P<0·001). In the same sample, the second study found cognitive benefits of B-vitamins dependent on the higher baseline plasman-3 fatty acid status. The third B-vitamin study (n900; duration=2 years) reported improved performance in immediate (P=0·046) and delayed recall (P=0·013), whereas the fourth study (n856; duration=2 years) reported slower rate of cognitive decline in the MMSE (P=0·05). One study investigating DHA treatment (n402; duration=1·5 years) revealed the slower rate of cognitive change inapoE e4non-carriers (P=0·03). As only five included studies revealed notable benefits, presently based on the specific compounds explored here, there is not compelling evidence to support the use nutraceuticals to improve cognition in the elderly. Future long-term trials of nutraceuticals should investigate interactions with lifestyle, blood biomarkers and genetic risk factors.
COMPLICITY IN VIOLATIONS OF HUMAN RIGHTS AND HUMANITARIAN LAW BY INCUMBENT GOVERNMENTS THROUGH DIRECT MILITARY ASSISTANCE ON REQUEST
Authors: de Wet Erika 
Published: January 2018

AbstractThis article examines whether general international law supports the claim that direct military assistance by one State to another State upon the latter's request is prohibited where the inviting State is implicated in (gross) violations of international humanitarian and/or human rights law. It approaches the question from the perspective of State responsibility, analysing the threshold requirements of Article 16 of the Articles on State Responsibility (ASR),1 which represents the customary international law standard for responsibility for aiding or assisting wrongful conduct by another State. In so doing, the article illuminates how factual uncertainties complicate the triggering of the responsibility of the intervening (assisting) State for any violations of international humanitarian and/or human rights law by the territorial (recipient) State. Thereafter, the article questions whether, in the event that the responsibility of the intervening State is triggered, it would in consequence have to withdraw its troops and/or military air power from the territorial State.

AbstractThe aim of this study was to evaluate the association between eosinophils in ascites and the diagnosis of intestinal anisakidosis in patients with peritoneal signs on physical examination. We reviewed retrospectively 16 patients diagnosed with intestinal anisakidosis, evaluated between 2012 and 2015. All patients had ingested raw anchovies. The analysis of ascites fluid in ten of these patients was compared with that of 15 patients with ascites and other abdominal pathology (except liver cirrhosis). All patients had an increased number of white blood cells in the ascites fluid. The eosinophil count was significantly higher in patients with intestinal anisakidosis (P < 0.01). All patients had a good outcome. Increased eosinophils in ascites fluid is strongly associated with the diagnosis of intestinal anisakidosis.

Published: January 2018

AbstractObjective:To explore the link between nasal polyposis, refractory otitis media with effusion and eosinophilic granulomatosis with polyangiitis.Methods:A retrospective observational study was carried out of patients diagnosed with refractory otitis media with effusion necessitating grommet insertion and who had nasal polyps. Patients were evaluated to determine if they fulfilled the diagnostic criteria of eosinophilic granulomatosis with polyangiitis.Results:Sixteen patients (10 males and 6 females) were identified. The mean age of grommet insertion was 45.4 years. The mean number of grommets inserted per patient was 1.6. The mean number of nasal polypectomies was 1.7. All 16 patients had paranasal sinus abnormalities and otitis media with effusion, 14 had asthma, 9 had serological eosinophilia and 7 had extravascular eosinophilia. Nine patients met the diagnostic criteria for eosinophilic granulomatosis with polyangiitis.Conclusion:The co-presence of nasal polyps and resistant otitis media with effusion should raise the possibility of eosinophilic granulomatosis with polyangiitis.
