Tooth Development Associated with Mutations in Hereditary Vitamin D–Resistant Rickets
Authors: Hanna A.E. , Sanjad S. , Andary R. , Nemer G. , Ghafari J.G. 
Published: September 2017

Hereditary vitamin D–resistant rickets (HVDRR) is a rare genetic disorder caused by mutations at the level of the vitamin D receptor ( VDR) gene. The disease is characterized by refractory hypocalcemia, elevated serum levels of 1,25-dihydroxy-vitamin D, retarded growth, sparse body hair (sometimes alopecia), premature tooth loss, enlarged pulp chambers, thin dentine, and hypoplastic enamel. The aims of this study were 1) to document the dental development of children with HVDRR in association with the mutation type within the VDR and 2) to evaluate the association between dental development and the timing of and response to HVDRR treatment. Genome analysis was performed for 4 affected children (2 y 2 mo to 6 y 8 mo) under treatment with high doses of vitamin D and calcium. Longitudinal records of clinical and radiographic data on their dental development were assessed in relation to genetic profile and response to treatment. Treatment success depended on the position of the mutation within the VDR protein: children with the p.R391S mutation had a favorable outcome but maintained alopecia totalis, while 1 child with the p.H397P mutation and normal hair had no response to very high doses of vitamin D. The primary incisors, formed prenatally and first to emerge, were missing in 3 children and mobile in 1 child; parents reported loss within months posteruption. Posterior teeth were present, having erupted after treatment initiation. Hypoplastic enamel in emerging teeth was associated with late treatment onset. Mutation type in the VDR gene appears to be related to differences in the disease phenotype and response to treatment. Dental development represents an indicator of the disease process, initially protected by maternal blood levels of calcium and later restored by therapeutic supplies that normalize these levels. Knowledge Transfer Statement: Two novel mutations were associated with different HVDRR phenotypes, one of which responded positively to treatment. Early detection of the mutation should help pediatricians forecast treatment protocol and response. The results also highlight the direct relationship between dental development and blood calcium levels, underscoring the importance of early diagnosis and treatment of HVDRR to minimize the loss of primary teeth and reduce structural abnormalities of permanent teeth.
Make researchers revisit past publications to improve reproducibility
Authors: Fiala Clare , Diamandis Eleftherios P. 
Published: September 2017

Scientific irreproducibility is a major issue that has recently increased attention from publishers, authors, funders and other players in the scientific arena. Published literature suggests that 50-80% of all science performed is irreproducible. While various solutions to this problem have been proposed, none of them are quick and/or cheap. Here, we propose one way of reducing scientific irreproducibility by asking authors to revisit their previous publications and provide a commentary after five years. We believe that this measure will alert authors not to over sell their results and will help with better planning and execution of their experiments. We invite scientific journals to adapt this proposal immediately as a prerequisite for publishing.
Gradual physical decline characterises the illness trajectories of care home residents
Authors: Finucane Anne M , Stevenson Barbara , Murray Scott A 
Published: September 2017

Background: Three archetypal trajectories of physical decline have been identified: a short period of rapid decline; long-term limitations with intermittent acute periods; and a prolonged gradual decline. An understanding of illness trajectories can help clarify the evolving needs of people with progressive conditions, and inform the development of palliative care services to meet their needs. Many frail older people live and die in care homes; the present study is the first to explore the illness trajectories of residents in care home settings. Aims: To determine the prevailing trajectories of physical decline in care home residents; and to identify the dominant illness trajectories of residents in care homes in Lothian, Scotland. Method: Data were collected as part of a service development project to improve palliative care in eight care homes in south Edinburgh that provided 24-hour onsite nursing care. Results: Data on 120 residents were collected. The dominant illness trajectory, found in 78% of residents, was prolonged gradual decline. The majority of residents (67%) had two or more long-term conditions. Overall, 74% had dementia. Only 11% of residents died in hospital; of these, most died within 1 week of admission. Conclusion: Interventions to improve palliative care in care homes need to be modelled on the needs of residents who experience prolonged gradual decline characterised by frailty, dementia, multimorbidity and an uncertain prognosis.

Iterative calculus on tangent floors
Authors: Balan Vladimir , Rahula Maido , Voicu Nicoleta 
Published: September 2017

Abstract
Tangent fibrations generate a “multi-floored tower”, while raising from one of its floors to the next one, one practically reiterates the previously performed actions. In this way, the "tower" admits a ladder-shaped structure. Raising to the first floors suffices for iteratively performing the subsequent steps. The paper mainly studies the tangent functor. We describe the structure of multiple vector bundle which naturally appears on the floors, tangent maps, sector-forms, the lift of vector fields to upper floors. Further, we show how tangent groups of Lie groups lead to gauge theory, and explain in this context the meaning of covariant differentiation. Finally, we will point out within the floors special subbundles - the osculating bundles, which play an essential role in classical theories.

A local minimum theorem and critical nonlinearities
Authors: Bonanno Gabriele , D’Aguì Giuseppina , O’Regan Donal 
Published: September 2017

Abstract
In this paper the existence of two positive solutions for a Dirichlet problem having a critical growth, and depending on a real parameter, is established. The approach is based on methods which are totally variational, unlike the fundamental result of Ambrosetti, Brezis and Cerami where a clever combination of topological and variational methods is used in order to obtain the same conclusion. In addition, a numerical estimate of real parameters, for which the two solutions are obtained, is provided. Our main tool is a local minimum theorem.
Classification of Filiform Lie Algebras up to dimension 7 Over Finite Fields
Authors: Falcón Óscar J. , Falcón Raúl M. , Núñez Juan , Pacheco Ana M. , Villar M. Trinidad 
Published: September 2017

Abstract
This paper tries to develop a recent research which consists in using Discrete Mathematics as a tool in the study of the problem of the classification of Lie algebras in general, dealing in this case with filiform Lie algebras up to dimension 7 over finite fields. The idea lies in the representation of each Lie algebra by a certain type of graphs. Then, some properties on Graph Theory make easier to classify the algebras. As main results, we find out that there exist, up to isomorphism, six, five and five 6-dimensional filiform Lie algebras and fifteen, eleven and fifteen 7-dimensional ones, respectively, over ℤ/pℤ, for p = 2, 3, 5. In any case, the main interest of the paper is not the computations itself but both to provide new strategies to find out properties of Lie algebras and to exemplify a suitable technique to be used in classifications for larger dimensions.
On the weak limit of compact operators on the reproducing kernel Hilbert space and related questions
Authors: Saltan Suna 
Published: September 2017

Abstract
By applying the so-called Berezin symbols method we prove a Gohberg- Krein type theorem on the weak limit of compact operators on the non- standard reproducing kernel Hilbert space which essentially improves the similar results of Karaev [5]: We also in terms of reproducing kernels and Berezin symbols investigate the structure of invariant subspaces of compact operators.
Analysis of the energy decay of a viscoelasticity type equation
Authors: Atallah-Baraket Amel , Trabelsi Maryem 
Published: September 2017

Abstract
In this paper, we study the evolution of the energy density of a sequence of solutions of a problem related to a viscoelasticity model where the viscosity term is a pseudo-differential operator of order 2α with α ∈ (0, 1). We calculate the weak limit of the energy density in terms of microlocal defect measures and under special assumption we prove that the viscosity term prevents propagation of concentration and oscillation effects contrary to what happens in the wave equation.

Published: September 2017

Abstract
We do a qualitative study on the mixed initial-boundary value problem in the elastodynamic theory of microstretch bodies. After we trans- form this problem in a temporally evolutionary equation on a Hilbert space, we will use some results from the theory of semigroups of linear operators in order to prove the continuous dependence of the solutions upon initial data and supply terms.

Published: September 2017

Abstract
In this paper we define and study a new class of subfuzzy hypermodules of a fuzzy hypermodule that we call normal subfuzzy hypermodules. The connection between hypermodules and fuzzy hypermodules can be used as a tool for proving results in fuzzy hypermodules. In this manner we analyse three isomorphism theorems for fuzzy hypermodules.
Classification of contact structures associated with the CR-structure of the complex indicatrix
Authors: Popovici Elena 
Published: September 2017

Abstract
By regarding the complex indicatrix as an embedded CR-hypersurface of the holomorphic tangent bundle in a fixed point, we analyze some aspects of the relations between its CR structure and the considered contact structure. Moreover, using the classification of the almost contact metric structures associated with a strongly pseudo-convex CR-structure, of D. Chinea and C. Gonzales, we determine the classes corresponding to the natural contact structure of the complex indicatrix and the new structures obtained under a gauge transformation.
Hardness Evolution and High Temperature Mechanical Properties of Laser Welded DP980 Steel Joints
Authors: Wan Zhandong , Guo Wei , Jia Qiang , Xu Lang , Peng Peng 
Published: September 2017

AbstractDP980 steels were joined using fiber laser welding. The welded joint was characterized in terms of hardness distribution and tensile behavior at room temperature, 150 ℃, and 300 ℃, respectively. The fine-grained martensite in supercritical heat affected zone (HAZ) resulted in the highest hardness (428 Hv), while the tempered martensite contributed to the hardness decreasing (‒31 Hv). Both the ultimate tensile strength and yield strength of the base metal and welded joint decreased at 150 ℃, and then increased at 300 ℃ due to dynamic strain aging (DSA). The welded joint exhibited slightly higher yield strength and lower elongation at all the test temperatures compared to base metal due to the hardened fusion zone. The energy absorption reduced slightly with increasing temperature both for base metal and welded joint, and the weld posed a minor effect on the energy absorption. Deformation was one of the requirements for DSA effect. DSA enhanced the hardness of base metal (+78 Hv) and softened zone (+53 Hv). HAZ was not softened enough to become the weakest position during tensile test.
Equity versus equality norms of justice and organisational commitment: the moderating role of gender
Authors: Ramamoorthy Nagarajan , Stringer Donna 
Published: September 2017

AbstractIn the current study, using a sample of 467 employees from Ireland, we examined the effects of distributive justice perceptions, based on equity versus equality principles, on two forms of employee commitment: affective and normative. Furthermore, we also tested whether employees’ gender moderated the relationships between these two distributive justice perceptions and the two forms of commitment. Results indicated that equity perceptions positively influenced both forms of commitment and equality perceptions positively influenced only normative commitment. Additionally, results revealed that women reported greater affective and normative commitments than men when equity perceptions were higher than when they were lower. Gender did not moderate the relationship between equality perceptions and normative commitment. Women, however, reported lower affective commitment than men when equality perceptions were lower; there were no differences between men and women on affective commitment when equality perceptions were higher. Implications are discussed.

Imaging of buried objects from multi-frequency experimental data using a globally convergent inversion method
Authors: Nguyen Dinh-Liem , Klibanov Michael V. , Nguyen Loc H. , Fiddy Michael A. 
Published: September 2017

Abstract
This paper is concerned with the numerical solution to a three-dimensional coefficient
inverse problem for buried objects with multi-frequency experimental data.
The measured data, which are associated with a single direction of an incident
plane wave, are backscatter data for targets buried in a sandbox.
These raw scattering data were collected using a microwave scattering facility at the University
of North Carolina at Charlotte.
We develop a data preprocessing procedure and
exploit a newly developed globally convergent inversion method for solving the
inverse problem with these preprocessed data.
It is shown that dielectric constants of the buried targets as well as their
locations are reconstructed with a very good accuracy. We also prove a new analytical
result which rigorously justifies an important step of the so-called
“data propagation” procedure.
Rigorous upper bounds on data complexities of block cipher cryptanalysis
Authors: Samajder Subhabrata , Sarkar Palash 
Published: September 2017

AbstractStatistical analysis of symmetric key attacks aims to obtain an expression for the data complexity which is the number of plaintext-ciphertext pairs needed to achieve the parameters of the attack. Existing statistical analyses invariably use some kind of approximation, the most common being the approximation of the distribution of a sum of random variables by a normal distribution. Such an approach leads to expressions for data complexities which are

Design and Applications of Sensitive Enzyme Immunoassays Specific for Clostridial Enoate Reductases
Authors: Krause Günter , Simon Helmut 
Published: September 2017

Abstract
Rabbit antisera raised against purified enoate reductase from Clostridium tyrobutyricum (DSM 1460) and horse-radish peroxidase-conjugated staphylococcal protein A or anti-rabbit immuno­ globulin G, respectively, were used to develop enzyme immunoassays. Sensitivity limits of the assay are about 250 pg antigen if the enzyme immunoassays are performed on membrane filters and examined visually, and 20 pg for tests in aqueous solution with spectrophotometrical evalua­tion. The procedures were applied for dot and Western blots as well as colony lifts. Immunologi­ cal distances between enoate reductases from different Clostridia were determined and the amounts of antigen present in bacterial crude extracts were estimated. In crude extracts of C. thermoaceticum a protein of approximately the size of the enoate reductase and its subunits from C. tyrobutyricum was immunologically detected. Gel filtration chromatography of identically pretreated crude extracts from C. thermoaceticum and C. tyrobuty­ricum produced immunological signals at similar molecular weights and revealed a lesser tendency of the presumed thermophilic enoatereductase from C. thermoaceticum to disintegrate into its subunits and fragments as compared to its mesophilic counterpart.
Survey of the Plant Kingdom for the Ability to Bind Heavy Metals through Phytochelatins
Authors: Gekeler Walter , Grill Erwin , Winnacker Ernst-Ludwig , Zenk Meinhart H. 
Published: September 2017

Abstract
Differentiated plants and suspension cultures of the taxonomic divisions Bryophyta, Pteridophyta, and Spermatophyta have been investigated as to their ability to detoxify heavy metals like Cd2+ through the formation of (γ-Glu -Cys)n-Giy peptides, the phytochelatins. Over 200 individual plants have been checked and there was not a single exception observed. Only in the order Fabales several species mainly of the tribus Fabaceae form upon exposure to Cd2+ ions peptides of the general structure (γ-Glu-Cys)n -β-Ala, the homo-phytochelatins. The existence of glutathione and homo-glutathione within a given species determines whether phytochelatins or their homo-derivatives are formed. The ability to form phytochelatins for metal homeostasis and metal detoxification is a principal feature of plant metabolism .
Sulphate Assimilation in Higher Plants: A Thioredoxin-Dependent PAPS-Reductase from Spinach Leaves
Authors: Schwenn J. D. 
Published: September 2017

Abstract
Higher plant leaf protein was investigated for the enzyme activity catalyzing a thioredoxin-dependent reduction of 3'-phosphoadenylylsulphate (PAPS) to sulphite. The enzyme became detectable when heterologous thioredoxin from Escherichia coli was used substituting for the hitherto unidentified plant thioredoxin. The enzyme's cross-reactivity with heterologous thioredo­ xin enabled the partial purification and brief characterization. The molecular weight of the en­ zyme as estimated by HPLC size exclusion and gel filtration was 68-72 k. The protein reduced PAPS only when thioredoxin was present as cosubstrate. The function of this enzyme in the assimilation of inorganic sulphate by higher plants is discussed in comparison to the function of the respective enzymes from Escherichia coli and Saccharom yces cerevisiae.

ABSTRACT
ONE IMPORTANT RESPONSIBILITY OF A STRENGTH AND CONDITIONING COACH IS THE DEVELOPMENT OF A TRAINING PROGRAM THAT ENHANCES PHYSIOLOGICAL QUALITIES, WITH THE GOAL OF IMPROVING ATHLETIC PERFORMANCE. TO ACHIEVE THIS GOAL, COACHES DESIGN TRAINING PROGRAMS THAT SUCCESSFULLY APPROPRIATE AND MANAGE TRAINING VOLUME AND INTENSITY DURING THE ATHLETE'S OFFSEASON, PRESEASON, AND IN-SEASON PERIODS. BY QUANTIFYING TRAINING LOADS AND RESPONSES, COACHES CAN BETTER PRESCRIBE TRAINING STIMULI WHILE ALSO MANAGING STRESS LEVELS. ATHLETE-MONITORING STRATEGIES PROVIDE A WAY FOR STRENGTH COACHES TO GATHER USEFUL INFORMATION REGARDING TRAINING DEMANDS AND ATHLETE FATIGUE.
