Pushout Invariance Revisited
Authors: Hager Anthony W. , Martínez Jorge 
Published: July 2016

Abstract
With modest standing assumptions on a category C, it is shown that a Galois connection exists between subclasses of C-objects (on the one hand) and classes of epimorphisms of C (on the other). In this connection the following classes are in a one-to-one correspondence, which reverses inclusion: the epireflective classes of C-objects with the classes ε of epimorphisms which are pushout invariant, in the sense that, for each pushout diagram

in which e ∈ ε, then it follows that n ∈ ε. The paper then examines some of the consequences of this result, and in so doing “revisits” the pushout invariance of the authors as it was discussed in a paper of some fifteen years ago.
Radius, Diameter and the Degree Sequence of a Graph
Authors: Mazorodze Jaya Percival , Mukwembi Simon 
Published: July 2016

Abstract
We give asymptotically sharp upper bounds on the radius and diameter of
(i) a connected graph,
(ii) a connected triangle-free graph,
(iii) a connected C4-free graph of given order, minimum degree, and maximum degree.
We also give better bounds on the radius and diameter for triangle-free graphs with a given order, minimum degree and a given number of distinct terms in the degree sequence of the graph. Our results improve on old classical theorems by Erd˝os, Pach, Pollack and Tuza [Radius, diameter, and minimum degree, J. Combin. Theory Ser. B 47 (1989), 73-79] on radius, diameter and minimum degree.

Published: July 2016

Abstract
We characterize the set of regular elements of an ordered semigroup S which is a left (right) ideal, an ideal, a bi-ideal or a quasi-ideal of S using the left (resp. right) ideal

and the quasi-ideal LE(S)∩RE(S) of S, where E(S) is the set of elements of S for which e ≤ e2. Illustrative example is given.
A Result Concerning Additive Mappings in Semiprime Rings
Authors: Fos̆ner Maja 
Published: July 2016

Abstract
In this paper we prove the following result. Let R be a 2-torsion free semiprime ring and let f : R → R be an additive mapping satisfying the relation f(x)x2 + x2f(x) = 0 for all x ∈ R. In this case f = 0. Any semisimple Banach algebra (for example, C* algebra) is semiprime. Therefore this algebraic result might be of some interest from functional analysis point of view.
On Booth Lemniscate and Hadamard Product of Analytic Functions
Authors: Piejko Krzysztof , Sokół Janusz 
Published: July 2016

Abstract
In [RUSCHEWEYH, S.-SHEIL-SMALL, T.: Hadamard product of schlicht functions and the Poyla-Schoenberg conjecture, Comment. Math. Helv. 48 (1973), 119-135] the authors proved the P`olya-Schoenberg conjecture that the class of convex univalent functions is preserved under convolution, namely K ∗ K = K. They proved also that the class of starlike functions and the class of close-to-convex functions are closed under convolution with the class K. In this paper we consider similar convolution problems for some classes of functions. Especially we give a new applications of a result [SOKÓŁ, J.: Convolution and subordination in the convex hull of convex mappings, Appl. Math. Lett. 19 (2006), 303-306] on the subordinating relations in the convex hull of convex mappings under convolution. The paper deals with several ideas and techniques used in geometric function theory. Besides being an application to those results it provides interesting corollaries concerning special functions, regions and curves.

The Interior Euler-Lagrange Operator in Field Theory
Authors: Volná Jana , Urban Zbynĕk 
Published: July 2016

Abstract
The paper is devoted to the interior Euler-Lagrange operator in field theory, representing an important tool for constructing the variational sequence. We give a new invariant definition of this operator by means of a natural decomposition of spaces of differential forms, appearing in the sequence, which defines its basic properties. Our definition extends the well-known cases of the Euler-Lagrange class (Euler-Lagrange form) and the Helmholtz class (Helmholtz form). This linear operator has the property of a projector, and its kernel consists of contact forms. The result generalizes an analogous theorem valid for variational sequences over 1-dimensional manifolds and completes the known heuristic expressions by explicit characterizations and proofs.
On Iλ-Statistical Convergence in Locally Solid Riesz Spaces
Authors: Das Pratulananda , Savas Ekrem 
Published: July 2016

Abstract
In this paper, we extend some results concerning statistical convergence in locally solid Riesz spaces by introducing a more general idea of convergence, namely Iλ-statistical convergence. We investigate the ideas of Iλ-statistical-τ-convergence, Iλ-statistical-τ-boundedness and Iλ-statistical-τ-Cauchy condition of sequences in a locally solid Riesz space endowed with a topology τ and investigate some of their consequences.
Convexity in the Khalimsky Plane
Authors: Bouassida Ezzeddine , Gargouri Riyadh , Messaoud Rim 
Published: July 2016

Abstract
Let ℤ2 be equipped with the Khalimsky topology κ, it is a T0-Alexandroff topology which has some specific properties concerning continuity and connectivity. We define digital-arcs and the geodesics; this enables us to define D-convexity on the digital plane (ℤ2, κ). First, we prove a theorem dealing with the relationship between D-convexity and connectivity. The second result links together the convexity in ℝ2 and the D-convexity in ℤ2. For this purpose, we suggest the continuous digitization of the real line segment and thus prove that the digitization of a convex subset of ℝ2 is a D-convex subset of (ℤ2, κ).

Second Order Riemannian Mechanics
Authors: Matsyuk Roman 
Published: July 2016

Abstract
The technique of covariant differentiation is being implemented into the single integral variational calculus with second derivatives in Riemannian manifolds and into the Grässer-Rund-Weyssenhoff homogeneous generalized canonical framework for the parameter-invariant variational problem. As an example of physical nature we relate to each other the equations of motion with higher derivatives that describe the physical phenomena known as ‘Zitterbewegung’, the electromagnetic self-interaction, and spherical top. Although two of these phenomena, the quiver (the ‘Zitterbewegung’) and the radiation friction, have been known only within the framework of Special Relativity, our approach allows to generalize the corresponding equations of motion to the curved spacetime. From the geometrical point of view these generalizations depend neither on the signature of the Riemannian space nor on its dimension.
Recent sedimentation rates in the Caravelas estuary (Bahia, Brazil) using unsupported 210Pb and 137Cs modeling
Authors: Angeli José Lourenço Friedmann , Venturini Natalia , Ferreira Paulo Alves de Lima , Figueira Rubens César Lopes 
Published: July 2016

Abstract
The Caravelas estuary is located in a zone of the Brazilian coast (Southern Bahia State) which has
been submitted to different kinds of land uses during the last 50 years. This zone has an
important ecological role, due to its mangroves and its location next to Abrolhos coral reef, the
most important in the Southern Atlantic Ocean. 210Pb and 137Cs dating
methods, accompanied by a sedimentological study, were applied to sediment cores in order to
establish sedimentation rates and identify historical trends of land use and erosive
processes. Sedimentation rates were established according to the “Constant Rate of Supply”
(CRS) 210Pb dating model, which was preferred rather than the “Constant Initial
Concentration” (CIC) model. Corrected sedimentation rates obtained from 210Pb dating
were corroborated through a second independent radionuclide tracer such as 137Cs. The
sedimentation rates obtained according to the CRS model for the cores were 1.07  ±  0.13 cm yr
–1 for T#2 (inner sector), 0.65  ±  0.06 cm yr
–1
for T#5 and 0.85  ±  0.09 cm yr
–1 for T#8 (outer sector). The difference
in sedimentation rates among the sampling sites could be due to hydrodynamic processes and could
be related to the tendency of increase of erosive processes, conditioned by the changes in the
landscape and land use to, which this region has been submitted.
The Evaluation of the Equipment and Quality of the Public Space of Poznań
Authors: Budner Waldemar W. 
Published: July 2016

Abstract
The article defines the notion of public space and attempts to explain its forms and roles. The article realizes two cognitive goals: the evaluation of the equipment of public spaces in Poznań with the selected elements of landscape architecture and the quality of those spaces. Empirical research was conducted in the form of a survey addressed at 300 respondents. The research activities conducted in the course of work allow for the formulation of the following conclusions: the quality of life in a city depends on the condition of equipment of public space; the elements of landscape architecture make the public space of Poznań more attractive (contribute to its functionality, increase the aesthetics of urban space); the condition of the equipment of public space with landscape architecture is evaluated as good; the users of the public space in Poznań pointed out the problem of advertising pillars, advertisements and signboards, public toilets and the insufficient number of seats.
The Significance of Database Size in Modelling the Market of Nonresidential Premises
Authors: Barańska Anna 
Published: July 2016

Abstract
The market of non-residential premises is the subject of analyses less frequently than the housing market. There are two main reasons which probably contribute thereto. First of all, commercial premises are relatively less frequently objects of trade than dwelling units; secondly, they are more diverse due to their various uses. The category includes garages, office premises, commercial premises, as well as warehouses. Such differences in their uses result in significantly different characteristics, such as surface area.
The article attempts to analyse a selected non-residential segment of the commercial property market in Krakow based on a large set of data (280 objects), referring to the transactions concluded in the last five years. The size of the data enabled the use of multidimensional modelling of the selected market in different size variants. This made it possible to draw reliable conclusions which undermine the widespread belief regarding very limited possibilities of using the method of market statistical analysis in the comparative approach, especially in this segment of the real estate market, as well as in others, where transactions are concluded less frequently than on the housing market.
Fatality as a Feature of Medical Care
Authors: Ruiz-Sada Pablo , Atutxa-Fernández Jon-Ander , Fernández-Ferrer Sara , Palacios-García Lara 
Published: July 2016

Abstract
Taking advantage of an interesting clinical scenario, we want to introduce a discussion about fatality in our daily practice and the need to accept that. An 80 year-old man with non-traumatic spontaneous bleeding tendency came to the clinics. Although being on warfarin as a consequence of primary thrombotic prophylaxis due to an atrial fibrillation, full assessment was performed. Not only the rare entity found on him, but also the severe complication that happened afterwards challenged clinicians and led them to risky treatment options.
Malice Aforethought
Authors: Curry Philip A. 
Published: July 2016

AbstractThis paper examines why criminal intent matters in sentencing. In particular, it considers two types of crimes, opportunistic and premeditated. Opportunistic crimes are ones that present themselves to a criminal and can be deterred if the victim makes it too costly for the criminal through private property protection. Premeditated crimes are ones sought out by the criminal, and the effect of private property protection is simply to displace crime. This difference between deterrence and displacement leads to the result that it is optimal to punish premeditated crimes more. The extent to which this is true, however, lies in the response by potential victims. If victims protect themselves from premeditated crimes in ways that also protect them from opportunistic ones, then the difference in penalties is relatively less.
Digital Root Patterns of Three-Dimensional Space
Authors: Lin Chia-Yu 
Published: July 2016

Abstract
In this study, we define vedic cube as the layout of each digital root in a three-dimensional multiplication table. In order to discover the geometric patterns in vedic cube, we adopt two methods to analyze the digital root in a three-dimensional space. The first method is floor method, which divides vedic cube into several X-Y planes according to different Z values (floors) to analyze the geometric characteristics on each floor. The second method is symmetric plane method, which decomposes vedic cube by its main and secondary symmetric planes.
Endless Love: On the Termination of a Playground Number Game
Authors: Johnston Iain G. 
Published: July 2016

Abstract
A simple and popular childhood game, loves or the love calculator, involves an iterated rule applied to a string of digits and gives rise to surprisingly rich behaviour. Traditionally, players’ names are used to set the initial conditions for an instance of the game: its behaviour for an exhaustive set of pairings of popular UK childrens’ names, and for more general initial conditions, is examined. Convergence to a fixed outcome (the desired result) is not guaranteed, even for some plausible first name pairings. No pairs of top-50 common first names exhibit non-convergence, suggesting that it is rare in the playground; however, including surnames makes non-convergence more likely due to higher letter counts (for example, “Reese Witherspoon loves Calvin Harris”). Difierent game keywords (including from difierent languages) are also considered. An estimate for non-convergence propensity is derived: if the sum m of digits in a string of length w obeys m > 18=(3=2/)w-4, convergence is less likely. Pairs of top UK names with pairs of ‘O’s and several ‘L’s (for example, Chloe and Joseph, or Brooke and Scarlett) often attain high scores. When considering individual names playing with a range of partners, those with no loves letters score lowest, and names with intermediate (not simply the highest) letter counts often perform best, with Connor and Evie averaging the highest scores when played with other UK top names.
The Silence of Heads
Authors: Kayne Richard S. 
Published: July 2016

Abstract
On the basis of considerations involving complementizers, sentence-final particles,
need, aspect, tense, focus and topic, agreement morphemes, determiners, verbrelated
particles and adpositions, I reach the conclusion that many more heads
in the sentential projection line (and elsewhere) must be taken to be silent than is
usually thought. I then argue that this state of affairs ultimately reflects the fact
that every projecting head is silent.

Understanding S-Selection
Authors: Zhang Niina Ning 
Published: July 2016

Abstract
I report a few study notes of semantic selection in this paper. First, if derivational
affixes s-select roots, which have no categorial features, s-selection may be
implemented independently of c-selection. Second, in certain constructions, it
seems that s-selected features do not take part in the syntactic operations that
establish syntactic dependencies, and thus the inspection of s-selection seems
to be local to the merge domain. I also examine s-selection between phrases,
showing that it follows the same projection principle as seen in the c-selection
between phrases.

Bildungsinhalt ohne Bildungsgehalt? – Spiritualität in der Pflegeausbildung
Authors: Knoll OP Franziskus 
Published: July 2016

ZusammenfassungNormativ-ideelle Forderungen der Pflegewissenschaft, theologisch-anthropologische Überlegungen und empirische Studien von Gesundheitspsychologie und Medizin belegen, dass im Kontext gesundheitlicher Veränderungen nicht nur psychische, materielle, soziale und umweltbezogene Faktoren zu bedenken sind, sondern eben auch spirituelle. Insofern Spiritualität zum Menschsein dazu gehört, sie potentiell aktiviert werden kann und gesundheitliche Relevanz besitzt, stellt sich die Frage nach ihrem Ort als Bildungsinhalt im Ausbildungskanon der deutschen Pflege. Der vorliegende Beitrag befasst sich mit der Pflegerelevanz von Spiritualität, untersucht die Berücksichtigung spiritueller Bildungsinhalte in den Rahmenlehrplänen der deutschen Bundesländer und wirft einen Blick auf die Situation in der US-amerikanischen Krankenpflegeausbildung. Aus den Entwicklungen in Deutschland und den USA werden Chancen, Grenzen und Ansatzpunkte einer zukunftsfähigen Qualifikation Pflegender in der spirituellen Begleitung abgeleitet.
Prefrontal Single-Neuron Responses after Changes in Task Contingencies during Trace Eyeblink Conditioning in Rabbits
Authors: Siegel Jennifer J. 
Published: July 2016

AbstractA number of studies indicate that the medial prefrontal cortex (mPFC) plays a role in mediating the expression of behavioral responses during tasks that require flexible changes in behavior. During trace eyeblink conditioning, evidence suggests that the mPFC provides the cerebellum with a persistent input to bridge the temporal gap between conditioned and unconditioned stimuli. Therefore, the mPFC is in a position to directly mediate the expression of trace conditioned responses. However, it is unknown whether persistent neural responses are associated with the flexible expression of behavior when task contingencies are changed during trace eyeblink conditioning. To investigate this, single-unit activity was recorded in the mPFC of rabbits during extinction and reacquisition of trace eyeblink conditioning, and during training to a different conditional stimulus. Persistent responses remained unchanged after full extinction, and also did not change during reacquisition training. During training to a different tone, however, the generalization of persistent responses to the new stimulus was associated with an animal’s performance—when persistent responses generalized to the new tone, performance was high (>50% response rate). When persistent responses decreased to baseline rates, performance was poor (<50% response rate). The data suggest that persistent mPFC responses do not appear to mediate flexible changes in the expression of the original learning, but do appear to play a role in the generalization of that learning when the task is modified.
CTRL+INSERT: retrotransposons and their contribution to regulation and innovation of the transcriptome
Authors: Göke Jonathan , Ng Huck Hui 
Published: July 2016

AbstractThe human genome contains millions of fragments from retrotransposons—highly repetitive DNA sequences that were once able to “copy and paste” themselves to other regions in the genome. However, the majority of retrotransposons have lost this capacity through acquisition of mutations or through endogenous silencing mechanisms. Without this imminent threat of transposition, retrotransposons have the potential to act as a major source of genomic innovation. Indeed, large numbers of retrotransposons have been found to be active in specific contexts: as gene regulatory elements and promoters for protein‐coding genes or long noncoding RNAs, among others. In this review, we summarise recent findings about retrotransposons, with implications in gene expression regulation, the expansion of gene isoform diversity and the generation of long noncoding RNAs. We highlight key examples that demonstrate their role in cellular identity and their versatility as markers of cell states, and we discuss how their dysregulation may contribute to the formation of and possibly therapeutic response in human cancers.
From pseudohypoparathyroidism to inactivating PTH/PTHrP signalling disorder (iPPSD), a novel classification proposed by the EuroPHP network

ObjectiveDisorders caused by impairments in the parathyroid hormone (PTH) signalling pathway are historically classified under the term pseudohypoparathyroidism (PHP), which encompasses rare, related and highly heterogeneous diseases with demonstrated (epi)genetic causes. The actual classification is based on the presence or absence of specific clinical and biochemical signs together with anin vivoresponse to exogenous PTH and the results of anin vitroassay to measure Gsa protein activity. However, this classification disregards other related diseases such as acrodysostosis (ACRDYS) or progressive osseous heteroplasia (POH), as well as recent findings of clinical and genetic/epigenetic background of the different subtypes. Therefore, the EuroPHP network decided to develop a new classification that encompasses all disorders with impairments in PTH and/or PTHrP cAMP-mediated pathway.Design and methodsExtensive review of the literature was performed. Several meetings were organised to discuss about a new, more effective and accurate way to describe disorders caused by abnormalities of the PTH/PTHrP signalling pathway.Results and conclusionsAfter determining the major and minor criteria to be considered for the diagnosis of these disorders, we proposed to group them under the term ‘inactivating PTH/PTHrP signalling disorder’ (iPPSD). This terminology: (i) defines the common mechanism responsible for all diseases; (ii) does not require a confirmed genetic defect; (iii) avoids ambiguous terms like ‘pseudo’ and (iv) eliminates the clinical or molecular overlap between diseases. We believe that the use of this nomenclature and classification will facilitate the development of rationale and comprehensive international guidelines for the diagnosis and treatment of iPPSDs.
