Generalized friezes and a modified Caldero–Chapoton map depending on a rigid object
Authors: Holm Thorsten , Jørgensen Peter 
Published: July 2016

AbstractThe (usual) Caldero–Chapoton map is a map from the set of objects of a category to a Laurent polynomial ring over the integers. In the case of a cluster category, it mapsreachableindecomposable objects to the corresponding cluster variables in a cluster algebra. This formalizes the idea that the cluster category is acategorificationof the cluster algebra. The definition of the Caldero–Chapoton map requires the category to be 2-Calabi-Yau, and the map depends on a cluster-tilting object in the category. We study a modified version of the Caldero–Chapoton map which requires only that the category have a Serre functor and depends only on a rigid object in the category. It is well known that the usual Caldero–Chapoton map gives rise to so-calledfriezes, for instance, Conway–Coxeter friezes. We show that the modified Caldero–Chapoton map gives rise to what we callgeneralized friezesand that, for cluster categories of Dynkin typeA, it recovers the generalized friezes introduced by combinatorial means in recent work by the authors and Bessenrodt.
Decay estimates for solutions of nonlocal semilinear equations
Authors: Cappiello Marco , Gramchev Todor , Rodino Luigi 
Published: July 2016

AbstractWe investigate the decay for |x|→∞ of weak Sobolev-type solutions of semilinear nonlocal equationsPu = F(u).We consider the case whenP = p(D)is an elliptic Fourier multiplier with polyhomogeneous symbolp(ξ), and we derive algebraic decay estimates in terms of weighted Sobolev norms. Our basic example is the celebrated Benjamin–Ono equationfor internal solitary waves of deep stratified fluids. Their profile presents algebraic decay, in strong contrast with the exponential decay for KdV shallow water waves.
On modules of finite projective dimension
Authors: Dutta S. P. 
Published: July 2016

AbstractWe address two aspects of finitely generated modules of finite projective dimension over local rings and their connection in between: embeddability and grade of order ideals of minimal generators of syzygies. We provide a solution of the embeddability problem and prove important reductions and special cases of the order ideal conjecture. In particular, we derive that, in any local ringRof mixed characteristicp&gt; 0, wherepis a nonzero divisor, ifIis an ideal of finite projective dimension overRandp𝜖Iorpis a nonzero divisor onR/I, then every minimal generator ofIis a nonzero divisor. Hence, ifPis a prime ideal of finite projective dimension in a local ringR, then every minimal generator ofPis a nonzero divisor inR.

Application and simplified proof of a sharp L2 extension theorem
Authors: Ohsawa Takeo 
Published: July 2016

AbstractAs an application of a sharpL2extension theorem for holomorphic functions in Guan and Zhou, a stability theorem for the boundary asymptotics of the Bergman kernel is proved. An alternate proof of the extension theorem is given, too. It is a simplified proof in the sense that it is free from ordinary differential equations.
Stochastic calculus over symmetric Markov processes with time reversal
Authors: Kuwae K. 
Published: July 2016

AbstractWe develop stochastic calculus for symmetric Markov processes in terms of time reversal operators. For this, we introduce the notion of the progressively additive functional in the strong sense with time-reversible defining sets. Most additive functionals can be regarded as such functionals. We obtain a refined formula between stochastic integrals by martingale additive functionals and those by Nakao's divergence-like continuous additive functionals of zero energy. As an application, we give a stochastic characterization of harmonic functions on a domain with respect to the infinitesimal generator of semigroup on L2-space obtained by lower-order perturbations.
Can corrective feedback on second language speech perception errors affect production accuracy?
Authors: LEE ANDREW H. , LYSTER ROY 
Published: July 2016

ABSTRACTThis study investigated whether different types of corrective feedback (CF) in second language speech perception training have differential effects on second language speech production. One hundred Korean learners of English were assigned to five different groups and participated in eight computer-assisted perception training sessions focusing on English vowels. While no CF was provided to the control group, participants in the four treatment groups received one of three types of auditory CF or a visual type of CF. A pretest, an immediate posttest, and a delayed posttest each consisted of a production measurement at a controlled-speech level. Results revealed that the extent to which the participants’ production accuracy benefited from the perception training depended on CF type. In addition, by adopting the perception accuracy data by Lee and Lyster (2016b), the current study found that improvement in perception accuracy was a significant predictor of improvement in production accuracy.
Metalinguistic awareness in bilingual children's word reading: A cross-lagged panel study on cross-linguistic transfer facilitation
Authors: ZHANG DONGBO , CHIN CHERN-FAR , LI LI 
Published: July 2016

ABSTRACTThis longitudinal study examined metalinguistic awareness in bilingual word reading development among Malay–English bilingual children in Singapore. Participants were assessed with the same tasks twice with a 1-year interval from Grade 3 to Grade 4 in phonological and morphological awareness and derived word decoding in both English and Malay. Structural equation modeling analyses revealed that both types of metalinguistic awareness significantly predicted derived word reading in both languages. Subsequent cross-lagged panel modeling found construct-level transfer facilitation effect from Malay on English for phonological awareness but conversely from English on Malay for morphological awareness. Neither type of metalinguistic awareness exerted a transfer facilitation effect on word reading. These findings shed light on the developmental mechanism of cross-linguistic transfer in biliteracy acquisition.
Animal welfare: the five freedoms and the free market
Authors: Webster A. J. F. 
Published: July 2016

AbstractIn a free market economy the consumer and not the producer usually dictates the product and the means of production. Meat production however involves, as a third party, the animals themselves whose rights are not protected by the free market. To ensure and improve the welfare of farm animals it is necessary first to define and analyse the factors that contribute to an animal's sense of health and well-being. The first stage of analysis can be embraced by the five freedoms which define standards of nutrition, comfort, health, security and normal behaviour. Right action to ensure the five freedoms requires research, legislation and education. This paper suggests reasons why the contribution of research and legislation to improved welfare has, so far, been small. It further suggests that proposed future legislation may be too crude an instrument to ensure improvements in something so complex as an animal's perception of the world. The most promising approach is to educate the consumer towards an understanding of animal production that is more in tune with reality and less susceptible to imagery, be it the false ‘farm fresh’ image of the producers or the ‘factory’ image of the anti-farming lobby. My simple plea is for honesty in animal production, an honesty that recognizes the realities of pain and death but which allows both the farmer and his animals to live with dignity.
Controlling reproduction in sheep
Authors: Haresign W. 
Published: July 2016

AbstractIntravaginal progestagen pessaries + pregnant mare's serum gonadotrophin (PMSG) for controlling the oestrous cycle and for inducing out-of-season breeding have been commercially available for many years. However, extremely good mating management is required if acceptable results are to be achieved. More recently the role of the pineal hormone, melatonin, in the regulation of seasonal breeding has been recognized, and this has led to the development of slow-release formulations for use under farm conditions. Early indications are that such preparations can advance the breeding season by about 4 to 6 weeks, with lambing percentages in early (January) lambing flocks comparable with those of traditional (March) lambing flocks.Recent developments in the use of laparoscopy as an aid to intrauterine insemination and multiple ovulation and embryo transfer (MOET) should play a major role in breed improvement. Intrauterine insemination can markedly improve conception rates following the use of frozen semen compared with the conventional cervical technique, as well as eliminating the incidence of fertilization failure in embryo transfer donors. In addition, laparoscopic collection and transfer of embryos permit repeated collections from the same donor ewes and are much more acceptable than surgical techniques from the welfare point of view.
On functions of bounded variation

Published: July 2016

AbstractThe recently introduced concept of ${\mathcal D}$-variation unifies previous concepts of variation of multivariate functions. In this paper, we give an affirmative answer to the open question from [20] whether every function of bounded Hardy–Krause variation is Borel measurable and has bounded ${\mathcal D}$-variation. Moreover, we show that the space of functions of bounded ${\mathcal D}$-variation can be turned into a commutative Banach algebra.
Preserving Dignity in Later Life

Published: July 2016

RÉSUMÉCet article examine comment les personnes âgées qui recoivent l’aide sociale dans la communauté subissent une perte de la dignité et comment ils conservent leur dignité. La recherche qualitative a révélé que la perte de dignité est une préoccupation majeure pour ces aînés, et qu’ils conservent leur dignité de differentes manières, variant de s’engager activement à la vie jusqu’à s’en détacher. Nous concluons que, dans la vie plus tard, la préservation de la dignité tout en recevant dessoins sociauxdiffère de conserver la dignité dans le contexte dessoins de sante, en particulier les soins de santé fournis dans un cadre institutionnel. En outre, conserver la dignité en fin de vie, tout en recevant des soins sociaux, est un processus complexe, qui dépend non seulement de l’exécution des activités et la prise des actions individuelles et de leurs responsabilités, mais aussi d’autres actions, dont certaines impliquent une certaine inactivité/passivité, ainsi qu’interagir avec les autres, surtout les soignants. Cet article propose meilleures politiques et pratiques pour la promotion de la dignité des personnes âgeés dans le contexte de la protection sociale à base communautaire.
Urogenital dysfunction in patients with multiple sclerosis
Authors: Vodušek David B. 
Published: July 2016

Abstract:The occurrence of urogenital dysfunction as an isolated early symptom in multiple sclerosis (MS) is rare, but the prevalence thereof becomes high with progression of disease. Lower urinary tract dysfunction may add to the cause of death (particularly through urinary infections), but both urinary and sexual dysfunction significantly affect quality of life of patients.Both storage and evacuation of urine may be affected by MS, and ultimatively the functional diagnosis can only be made by urodynamic testing. As upper urinary tract affection is, however, rare (and can be prevented by timely ultrasound imaging), a first stage diagnostics in the MS center by the neurologist and specialized nurse is appropriate. History, urine tests and post void residual urine determination (preferably by ultrasound) should provide necessary data for treatment of infections, and also symptomatic management of frequency, urgency and incontinence by bladder training, anticholinergics, and intermittent self catheterization (as indicated); the referral to urologist may be reserved for patients who fail first line treatment. Treatment in the late stages of MS is as yet little researched, but eventually a suprapubic catheter is the preferred method of bladder emptying. Sexual dysfunction should be actively sought in MS patients (in men erectile and ejaculation dysfunction, in women deficient lubrication and genital hyper- or hyposensitivity are frequent). Clinical examination contributes little to clarification of neurogenic sexual dysfunction, but defines the extent of other deficits due to MS, which may be relevant for sexual counseling (spasticity, sensory loss). Sildenafil has been demonstrated to be effective in treatment of men, but not in women. Other management options exist, and the doctor and nurse in the MS center should be proactive in providing first line counseling and management.
Immunotherapy of multiple sclerosis
Authors: Meuth Sven G. , Bittner Stefan , Wiendl Heinz 
Published: July 2016

Abstract:Multiple sclerosis (MS) is regarded as a prototypic inflammatory autoimmune central nervous system disorder causing neurological disability in young adults. Recommended basic immunomodulatory therapies of MS are currently interferon beta and glatiramer acetate. Both have proven to be clinically and paraclinically effective and clinical evidence suggests that treatment should be initiated as early as possible.However, despite the fact that therapeutic options for MS have significantly been widened over the past decade there is still tremendous activity in the search for new treatment options for MS.One important development in the field is reflected by the substantial number of promising results for oral therapies. Various phase III clinical trials are currently being initiated or are already underway evaluating the efficacy of a variety of orally administered agents, including cladribine, teriflunomide, laquinimod, fingolimod and fumaric acid. It is hoped that these oral therapies for MS further broaden our armament for MS therapy.

Abstract:Introduction and aim:Posttraumatic stress disorder (PTSD) is associated with increased medical morbidity, particularly from the autoimmune and cardiovascular diseases. Changes in the endocrine and immune system are key mediators in this process. The aim of our study was to investigate weather hormones (cortisol and prolactin), proinflammatory cytokines (interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α)), components of HPA-axis (lymphocyte expression of glucocorticoid receptor (GR)), immune function (natural killer cell cytotoxicity) and peripheral blood percentages of various lymphocyte subpopulations (T cells, helper T cells, cytotoxic T cells, B cells and natural killer cells) change in patients with posttraumatic stress disorder over time.
Slowly progressive aphasia as the presenting symptom of dementing disorders
Authors: Wils V. , Godderis J. 
Published: July 2016

SummarySlowly progressive aphasia is an uncommon presenting symptom of a degenerative neurological disorder which in most cases eventually leads to a global dementia. The early recognition of this syndrome is sometimes hampered by the presence of accompanying or pre-existing psychiatric symptomatology. This is illustrated by two case reports. After a brief reflection on the nosological status of the disorder, the clinical picture and diagnosis are discussed.
Accuracy of register- and record-based bipolar I disorder diagnoses in Finland; a study of twins

ABSTRACTRegisters have been widely used in schizophrenia studies. For bipolar disorder, the use has been more limited and no studies exist concerning accuracy of bipolar I diagnoses in registers. We have collected an unselected twin sample for a study of bipolar I disorder. We report here the diagnostic procedures and accuracy of bipolar I diagnoses in a nation-wide hospital discharge registry. We evaluated also the accuracy of the medical record-based best-estimate diagnoses, comparing these with the SCID interview diagnoses. From the National Hospital Discharge Register we identified all like-sex twins, born 1940-1957, (N=42), and all like- or opposite-sex twins, born 1961-1969, (N=15), who had at least once a diagnosis of bipolar I disorder. The best-estimate diagnoses based on medical records, and were made by two doctors blind to each other, and according to DSM-IV-criteria. Diag-noses were then confirmed by SCID interviews, with the mi-nimum follow-up time after the first admission being 6 years. The accuracy of bipolar diagnoses in the register was 92% and 87%, accordingly. When comparing the best-estimate diagnoses to SCID interview diagnoses, there was one false positive case in the first sample, 3.4% [95% CI 0.1% to 7.8%], and none in the second sample. Our study shows that a diagnosis of bipolar I disorder in the hospital discharge register, or if based only on medical records, is highly reliable and stable. These results strengthen the usefulness of regis-ters also in bipolar disorder.
Typical and atypical antipsychotics in bipolar disorder
Authors: Licht R.W. 
Published: July 2016

ABSTRACTBackground: In clinical practice, typical antipsychotics are widely used in the treatment of bipolar disorder, albeit in treatment guidelines often considered as adjunctive agents only. Recently, focus has shifted towards the use of atypical antipsychotics. This paper reviews the advantages and disadvantages associated with the use of antipsychotics in bipolar disorder.Methods: Randomised controlled trials (RCTs) were selected for review. A few review articles were also cited.Results: Typical antipsychotics, at least some of them, are powerful antimanics, beneficial for severe agitation in particular. However, in the long term treatment, typical antipsychics may precipitate depression. Among the atypical antipsychotics, both risperidone and olanzapine are clearly antimanic alternatives, although olanzapine is the best studied. Clozapine seems to be useful when other treatments fail to work.Conclusions: Antipsychotics are beneficial for some clinical presentations of mania. To minimize side effets, atypical agents should be preferred before typical agents, unless parenteral administration is needed. Despite the lack of RCTs, antipsychotics also seem to be useful as adjunctive agents in the treatment of psychotic bipolar depression. For the long term treatment of bipolar disorder, typical antipsychotics should be used only under certain circumstances. The place of atypical antipsychotics in the long term treatment of bipolar disorder remains to be studied.
Predicting medication non-adherence in severe affective disorders
Authors: Scott J. 
Published: July 2016

AbstractObjective This study explored the utility of the Health Belief Models (HBM) in explaining medication adherence in subjects with severe affective disorders.Method Well established measuring instruments, with confirmed reliability and validity, were used to assess each component of two HBMs and adherence with mood stabilising medication in 104 subjects with bipolar (n=82), unipolar (n=18) or schizo-affective (n=4) disorders.Results Highly adherent and partially adherent subjects differed significantly in the stability of the level and the overall serum level of drug acheived. Subject's beliefs about themselves and their illness and their control over the disorder were more important than side-effects in predicting medication adherence. There were marked differences in the primary reasons for non-adherence identified by patients and their clinicians.Conclusion Although the study has a number of methodological limitations, the results suggest that clinical assessment of components of HBMs may improve the detection of patients at risk of non-adherence with mood stabilising medication.
Bipolar disorder in children and adolecents: a clinical reality?
Authors: Reichart C.G. , Nolen W.A. , Wals M. , Hillegers M.H.J. 
Published: July 2016

AbstractThe appearance, the differential diagnosis and the prevalence of bipolar disorder in children and adolescents is discussed. Among adolescents bipolar disorder appears to have a similar prevalence in the US and The Netherlands. However, among children it is frequently diagnosed in the US and hardly in The Netherlands. It is concluded that bipolar disorder tends to start earlier in the US than in the Netherlands. It is hypothesized that this may be related to a higher use of stimulants and antidepressants by US children diagnosed as ADHD or depression, respectively.
Circadian regulation of sleep propensity, sleep structure and alertness: A symphony of paradoxes
Authors: Dijk D.J. 
Published: July 2016

The adult human typically exhibits a monophasic sleep-wake cycle, i.e., remains awake and alert for approximately 16 hours and then sleeps for 8 hours. Recent experiments have provided new insights in the role of the endogenous circadian pacemaker in this consolidation of sleep and wakefulness.Sleep deprivation studies had shown previously that sleepiness and alertness are co-determined by a process which keeps track of the history of sleep and wakefulness and the circadian pacemaker, which keeps track of time. During every day life and during sleep deprivation both processes change simultaneously and their relative contribution to alertness and sleep propensity cannot be assessed under these conditions.

AbstractObjectiveShone’s syndrome is a complex consisting of mitral valve stenosis in addition to left ventricle outflow obstruction. There are a few studies evaluating the long-term outcomes in this population. We sought to determine the long-term outcomes in our paediatric population with Shone’s syndrome and the factors associated with left heart growth.MethodsAll patients diagnosed with Shone’s syndrome with biventricular circulation treated between 1978 and 2010 were reviewed. Baseline echocardiograms and data from catheterisations were also reviewed. Number of interventions (surgical+transcatheter), incidence of mitral valve replacement, and incidence of heart transplantation were tracked. Survival of the population and left heart structural growth were also reviewed.ResultsA total of 121 patients with Shone’s syndrome presented at a median age of 28 days (0–17.3 years) and were followed-up for 7.2 years (0.01–35.5 years). These patients underwent 258 interventions during the study period, and the presence of coarctation was associated with repeat left heart interventions. The 10-year, transplant-free survival was 86%. Presence of pulmonary hypertension was associated with mortality. Left heart structural growth was seen for mitral and aortic valve annuli and left ventricular end-diastolic dimension over time.ConclusionsShone’s syndrome patients undergo a number of left heart interventions. Coarctation of the aorta is associated with an increased likelihood for repeat interventions. Survival appears to be more favourable than expected. Significant left heart growth will occur in the population. Pulmonary hypertension is associated with an increased risk of mortality.
