On-line Search in Two-Dimensional Environment
Authors: Dereniowski Dariusz , Osula Dorota 
Published: September 2019

AbstractWe consider the following on-line pursuit-evasion problem. A team of mobile agents called searchers starts at an arbitrary node of an unknown network. Their goal is to execute a search strategy that guarantees capturing a fast and invisible intruder regardless of its movements using as few searchers as possible. We require that the strategy is connected and monotone, that is, at each point of the execution the part of the graph that is guaranteed to be free of the fugitive is connected and whenever some node gains a property that it cannot be occupied by the fugitive, the strategy must operate in such a way to keep this property till its end. As a way of modeling two-dimensional shapes, we restrict our attention to networks that are embedded into partial grids: nodes are placed on the plane at integer coordinates and only nodes at distance one can be adjacent. Agents do not have any knowledge about the grapha priori, but they recognize the direction of the incident edge (up, down, left or right). We give an on-line algorithm for the searchers that allows them to compute a connected and monotone strategy that guarantees searching any unknown partial grid with the use of$O(\sqrt {n})$O(n)searchers, wherenis the number of nodes in the grid. As for a lower bound, there exist partial grids that require${\varOmega }(\sqrt {n})$Ω(n)searchers. Moreover, we prove that for each on-line searching algorithm there is a partial grid that forces the algorithm to use${\varOmega }(\sqrt {n})$Ω(n)searchers but$O(\log n)$O(logn)searchers are sufficient in the off-line scenario. This gives a lower bound on${\varOmega }(\sqrt {n}/\log n)$Ω(n/logn)in terms of achievable competitive ratio of any on-line algorithm.
No head regeneration here: regeneration capacity and stem cell dynamics of Theama mediterranea (Polycladida, Platyhelminthes)
Authors: Bertemes Philip , Grosbusch Alexandra L. , Egger Bernhard 
Published: September 2019

AbstractResearch on the regeneration potential of flatworms (Platyhelminthes) has been mainly undertaken with planarians (Tricladida), where most species can regenerate a head and no proliferation takes place in the blastema, i.e. the early undifferentiated regenerative tissue. Only few studies are available for an early-branching group within the Platyhelminthes, the Polycladida. Head regeneration in polyclads is not possible, with a single exception from a study performed more than 100 years ago:Cestoplanawas reported to be able to regenerate a head if cut a short distance behind the brain. Here, we show that ‘Cestoplana’ was misdetermined and most likely was the small interstitial polycladTheama mediterranea. We revisited regeneration capacity and dynamics ofT. mediterraneawith live observations and stainings of musculature, nervous system, and proliferating and differentiating stem cells. In our experiments, after transversal amputation, only animals retaining more than half of the brain could fully restore the head including the brain. If completely removed, the brain was never found to regenerate to any extent. Different from planarians, but comparable to other free-living flatworms we detected cell proliferation within the posterior regeneration blastema inT. mediterranea. Similar to other free-living flatworms, proliferation did not occur within, but only outside, the differentiating organ primordia. Our results strongly imply that brain regeneration in the absence of the latter is not possible in any polyclad studied so far. Also, it appears that proliferation of stem cells within the regeneration blastema is a plesiomorphy in flatworms and that planarians are derived in this character.

Abstract

Purpose
To define the longitudinal rotation axis around which individual vertebrae rotate, and to establish the various extra- and intravertebral rotation patterns in thoracic adolescent idiopathic scoliosis (AIS) patients, for better understanding of the 3D development of the rotational deformity.

Methods
Seventy high-resolution CT scans from an existing database of thoracic AIS patients (Cobb angle: 46°–109°) were included to determine the vertebral axial rotation, rotation radius, intravertebral axial rotation, and local mechanical torsion for each spinal level, using previously validated image processing techniques.

Results
For all levels, the longitudinal rotation axis, from which the vertebrae rotate away from the midline, was localized posterior to the spine. The axis became closer to the spine at the apex: apex, r = 11.5 ± 5.1 cm versus two levels above (radius = 15.8 ± 8.5 cm; p < 0.001) and beneath (radius = 14.2 ± 8.2 cm; p < 0.001). The vertebral axial rotation, intravertebral axial rotation, and local mechanical torsion of the vertebral bodies were largest at the apex (21.9° ± 7.4°, 8.7° ± 13.5° and 3.0° ± 2.5°) and decreased toward the neutral, junctional zones (p < 0.001).

Conclusion
In AIS, the vertebrae rotate away around an axis that is localized posterior to the spine. The distance between this axis and the spine is minimal at the apex and increases gradually to the neutral zones. The vertebral axial rotation is accompanied by smaller amounts of intravertebral rotation and local mechanical torsion, which increases toward the apical region. The altered morphology and alignment are important for a better understanding of the 3D pathoanatomical development of AIS and better therapeutic planning for bracing and surgical intervention.

Published: September 2019

AbstractAlthough nonsuicidal self-injury (NSSI) is a clinically significant behavior, evidence-based, specific, time-, and cost-effective treatment approaches are lacking. The aim of this study was to compare the efficacies of a brief cognitive-behavioral psychotherapy manual, the Cutting Down Programme (CDP), and treatment as usual (TAU) in the treatment of adolescent NSSI. We conducted a single-centre randomised controlled trial (RCT). Eligible participants were aged 12–17 years engaging in repetitive NSSI (at least 5 times within the past 6 months). We randomly allocated 74 participants to CDP (n = 37) or TAU (n = 37; in a 1:1 ratio). Outcome measures were administered before treatment (T0), directly after CDP or 4 months after baseline evaluation in the TAU group (T1), and another 6 months later (T2; primary endpoint). Primary outcome was a 50% reduction in NSSI frequency within the past 6 months at 10-month follow-up (T2). Regarding the primary outcome, there were no significant differences between the CDP (n = 26; 70.3%) and TAU group [n = 27; 73.0%; χ2(1) = 0.07; p = 0.797]; NSSI frequency within the past 6 months was significantly reduced at T2 [χ2(1) = 12.45; p < 0.001] with no between-group difference [χ2(1) = 0.14; p = 0.704]. However, we found a significant group x point of measurement interaction [χ2(2) = 7.78; p = 0.021] regarding NSSI within the last month indicating at T1. CDP was equally effective and achieved faster recovery compared to a significantly more intensive TAU in treating adolescent NSSI. The CDP could provide a brief and pragmatic first treatment within a stepped-care model for NSSI in routine clinical care.Clinical Trial Registration The trial was prospectively registered in the German Registry of Clinical Trials (https://www.drks.de; DRKS00003605) and is now complete.

Abstract
Through our previous study, we found an up-regulation in the expression of nitrite reductase (nirS) in the isothiazolone-resistant strain of Pseudomonas aeruginosa. However, the definitive molecular role of nirS in ascribing the resistance remained elusive. In the present study, the nirS gene was deleted from the chromosome of P. aeruginosa ATCC 9027 and the resulting phenotypic changes of ΔnirS were studied alongside the wild-type (WT) strain under aerobic conditions. The results demonstrated a decline in the formations of biofilms but not planktonic growth by ΔnirS as compared to WT, especially in the presence of benzisothiazolinone (BIT). Meanwhile, the deletion of nirS impaired swimming motility of P. aeruginosa under the stress of BIT. To assess the influence of nirS on the transcriptome of P. aeruginosa, RNA-seq experiments comparing the ΔnirS with WT were also performed. A total of 694 genes were found to be differentially expressed in ΔnirS, of which 192 were up-regulated, while 502 were down-regulated. In addition, these differently expressed genes were noted to significantly enrich the carbon metabolism along with glyoxylate and dicarboxylate metabolisms. Meanwhile, results from RT-PCR suggested the contribution of mexEF-oprN to the development of BIT resistance by ΔnirS. Further, c-di-GMP was less in ΔnirS than in WT, as revealed by HPLC. Taken together, our results confirm that nirS of P. aeruginosa ATCC 9027 plays a role in BIT resistance along with biofilm formation and further affects several metabolic patterns under aerobic conditions.
Presumptions, and How They Relate to Arguments from Ignorance
Authors: Bodlović Petar 
Published: September 2019

AbstractBy explaining the argument from ignorance in terms of thepresumption of innocence, many textbooks in argumentation theory suggest that some arguments from ignorance might share essential features with some types of presumptive reasoning. The stronger version of this view, suggesting that arguments from ignorance and presumptive reasoning are almost indistinguishable, is occasionally proposed by Douglas Walton. This paper explores the nature and limits of the stronger proposal and argues that initial presumptions and arguments from ignorance arenotclosely connected. There are three main reasons. First, the argument from ignorance, unlike typical presumptive reasoning, is a negative kind of inference. Second, the typical initial presumption is sensitive to a broader set of defeaters and thus assumes a higher (negative) standard of acceptability. Third, in dialectical terms, initial presumption and argument from ignorance bring different attacking rights and obligations. I conclude that Waltonian intuition is unsupported or, at best, is limited only to practical presumptions and practical arguments from ignorance.

Published: September 2019

Abstract
Au nanoparticles supported on P25 TiO2 (Au/TiO2) were prepared by a facile sol-immobilisation method and investigated for the surface plasmon-assisted glycerol oxidation under base-free conditions. The Au/TiO2 samples were characterized by UV–vis spectroscopy and transmission electron microscopy. Catalysts were prepared using polyvinyl alcohol as stabiliser as well as in the absence of polymer stabiliser. Both the conversion and the reaction selectivity are affected by the plasmon-assisted oxidation and there is an interplay between the presence of the stabiliser and the Au nanoparticle size.

Conceptions, Norms, and Values in the Work of Child Protective Services with Families at Risk: An Analysis of Social Workers’ Diaries
Authors: Björkhagen Turesson Annelie 
Published: September 2019

AbstractSince the conceptions, norms, and values that govern the work of child protection are elusive, they are rarely discussed in the research. This study is based on diaries maintained by three social workers in relation to 15 families that were the subject of interventions by the child protective services in Sweden. All of the mothers in the 15 families had been diagnosed with mental health problems. The diaries include both significant events within the families and the social workers’ own feelings and perceptions about their work. This article discusses four themes:the Janus face of child protective services,clienthood and its conditions,child protective services and good or bad parenting, andthe fathers. The results show that the families were subjected to extensive discipline. The diaries also expressed strong value judgements regarding how children should be raised. The parents’ desires and wishes were redefined by the social workers, making the parents powerless. The fathers were marginalized, which meant that an important resource within the families was lost. The parents reacted to this exercise of power in part by trying to escape it and in part by adapting to it. In summary, the desire to help was in some cases transformed into an abusive exercise of power.
How different are different diff algorithms in Git?
Authors: Nugroho Yusuf Sulistyo , Hata Hideaki , Matsumoto Kenichi 
Published: September 2019

Abstract
Automatic identification of the differences between two versions of a file is a common and basic task in several applications of mining code repositories. Git, a version control system, has a diff utility and users can select algorithms of diff from the default algorithm Myers to the advanced Histogram algorithm. From our systematic mapping, we identified three popular applications of diff in recent studies. On the impact on code churn metrics in 14 Java projects, we obtained different values in 1.7% to 8.2% commits based on the different diff algorithms. Regarding bug-introducing change identification, we found 6.0% and 13.3% in the identified bug-fix commits had different results of bug-introducing changes from 10 Java projects. For patch application, we found that the Histogram is more suitable than Myers for providing the changes of code, from our manual analysis. Thus, we strongly recommend using the Histogram algorithm when mining Git repositories to consider differences in source code.

Abstract

Objective
The aim of the present study is evaluate the effectiveness of an Acceptance and Commitment Therapy (ACT)-based training protocol, in adjunct to token economy and previous parent training, in a sample of children with Attention-Deficit/Hyperactivity Disorder (ADHD). By promoting the reduction of immediate responses to thoughts and feelings, we aimed to reduce the impulsive behaviour of children and to improve their self-regulation.

Methods
The protocol was centred on awareness of the present moment, defusion and acceptance of feelings and emotions. Behavioural (Conners’ Parent Rating Scale -Revised: Long version, CPRS-R:L) and severity measures (Clinical Global Impression -Severity, CGI-S) were assessed before and after treatment in a clinical sample of 31 children aged 8–13 years.

Results
At the end of the ACT protocol, children showed significant improvement in global functioning and behavioural symptoms. There were significant improvements in the CPRS subscales Cognitive Problems (p = 0.005), Hyperactivity (p = 0.006), Perfectionism (p = 0.017), ADHD Index (p = 0.023), Global Index: Restless–Impulsive (p = 0.023), Global Index: Total (p = 0.036), DSM IV Inattentive (p = 0.029), DSM IV Hyperactive–Impulsive (p = 0.016), and DSM IV Total (p = 0.003). When controlling for the confounding effect of pharmacological therapy, comorbidities and socio-economic status, treatment maintained a significant effect on the CPRS subscales Perfectionism (partial η2 = 0.31, p < 0.01), Global Index: Restless–Impulsive (partial η2 = 0.29, p < 0.01), Global Index: Total (partial η2 = 0.31, p < 0.01), DSM IV Hyperactive–Impulsive (partial η2 = 0.20, p = 0.02). Symptom severity as rated by CGI-S scores decreased in 74.2% of the children.

Conclusions
This preliminary work on an Acceptance and Commitment Therapy-based child training in children affected by ADHD resulted in significant improvements, measured by a rating scale specific for ADHD.
Accountability and Relationship-Definition Among Food Banks Partnerships
Authors: Parker Marla A. , Mook Laurie , Kao Chen-Yu , Murdock Alex 
Published: September 2019

AbstractFood pantries typically operate in a partnership structure where they are primarily supported by a larger food bank. However, the ability to execute that mission through cooperative arrangements greatly depends upon accountability, a key dynamic that ensures partners are fulfilling expectations and key roles. This exploratory study utilizes qualitative interview data (n = 61) from a large food bank network to understand the extent to which a lead agency (i.e., a large food bank) meets expectations of accountability among partners. The interview results demonstrate that the extent to which expectations are met relate to different types of relationships between the lead agency and partner members. Furthermore, the ways in which partners assess the strengths or weaknesses of the food bank’s accountability reveal different types of relationships within the network, namely that of supplier–customer, supporter–customer, and supporter–collaborator.

Abstract
A hydrometallurgical method involving natural biomass waste as reductant was proposed for the treatment of spent mixed-type lithium-ion batteries. Results showed that almost complete dissolution of Li, Ni, Mn and nearly 90% dissolution of Co were achieved under the optimal conditions of H2SO4 concentration of 2 M, waste tea biomass dosage of 0.3 g/g, solid/ratio of 50 g L−1, temperature of 90°C and time of 120 min. The leaching kinetics was further investigated, and the activation energies were determined to be 1.7 kJ mol−1, 10.3 kJ mol−1, 10.1 kJ mol−1 and 10.9 kJ mol−1 for Li, Ni, Mn and Co, respectively. The cathode materials before leaching and the leaching residue were characterized with different analytical methods. The characterization results confirmed that the addition of the waste tea acted as reductant and resulted in better dissolution of the metals, supporting the principles of sustainable processes by decreasing the chemical consumption and integrating waste into a secondary use.

Published: September 2019

Abstract
Although simultaneous supplementation with iron and folic acid is justified, the potential interactions between these micronutrients are unknown. The aim of this study was to determine the effects of oral iron and folic acid, administered together or separately, on iron concentration in tissues in rats with a deficiency of both these micronutrients. In the first stage of the experiment (28 days), 150 8-week-old female Wistar rats were randomly assigned to a control group (C; n = 30) fed the standard diet and to a study group (n = 120) fed a diet deficit in iron and folate. The study group was then randomly divided to four groups: D group fed a deficit diet, FE group fed a deficit diet with iron gluconate, the FOL group fed a deficit diet with folate acid, and the FEFOL group fed a deficit diet with iron gluconate and folate acid. After 2, 10, and 21 days of supplementation, ten animals from each group were killed. Morphological parameters were measured in whole blood. Iron concentration was assayed in serum, liver, spleen, pancreas, heart, and kidneys. Folic acid supplementation more significantly decreased iron concentrations in the pancreas and spleen than in the D group after 10 and 21 days of supplementation. Moreover, the combination of iron with folic acid markedly decreased iron levels in the liver and spleen, in comparison with iron alone, after 10 and 21 days of the experiment. In conclusion, folic acid affects iron status in female rats deficient in these micronutrients in moderate and long-term supplementation.

Published: September 2019

AbstractIberian ‘warrior’ stelae have captured the imagination of researchers and the public for more than a century. Traditionally, stelae were considered ‘de-contextualised’ monuments, and research typically focused on the study of their iconography, paying little or no attention to their immediate contexts. As a result, despite the large number of these stelae known to date (c. 140) and the ample body of literature that has dealt with them, fundamental questions remain unanswered. This paper aims to demonstrate the potential of a multidisciplinary and contextual approach to push forward the research agenda on these monuments through a case study. Firstly, we introduce the Mirasiviene stela and the methods deployed for its investigation, which include a variety of digital imaging techniques, petrography, pXRF, intensive survey and multiscalar spatial analysis. Secondly, we discuss the results in relation to three main topics: stela biography, social practices and landscape context. Comparisons to the well-known nearby Bronze Age and Iron Age site of Setefilla are made throughout the discussion. Ultimately, this paper makes a case for the stelae of Mirasiviene and Setefilla being polyvalent monuments made by local artisans, that served both as landmarks and memorials in connection with dense late second and early first millennium BCE settlement patterns in the region. Probably linked to elites, ‘houses’ or kin groups of this time, stelae were set in symbolically charged places, liminal spaces nearby water, burials and pathways, attracting a range of ritual activities throughout the centuries. The study of the newly discovered Mirasiviene stela shows that multidisciplinary, cutting-edge non-destructive archaeology can shed significant new light on these prehistoric monuments, thus providing a glimpse of what in our opinion is a paradigm shift in the research of similar monuments throughout Europe.
