Infantile colic associated with childhood migraine: A prospective cohort study
Authors: Sillanpää Matti , Saarinen Maiju 
Published: March 2015

Purpose To explore the association between infantile colic and adolescent migraine. Method In a randomized general population sample, families expecting their first child were prospectively followed for infantile colic and adolescent migraine. Results Colic was diagnosed in 160 (13%) of 1267 infants until the age of 3 months. Migraine was ascertained in 129 (16%) of 787 adolescents at age 18 years. History of infantile colic was identified in 96 (12%) of 787 adolescents and no such history in 658 (88%) of 787 adolescents. Migraine was present in 22 (23%)/96 adolescents who had a history of infantile colic, but in only 74 (11%)/658 ones who had no such history. Of the 22 adolescents, 14 (64%) had migraine without aura and eight (36%) had migraine with aura. Infants with colic had an almost three-fold risk (risk ratio 2.8, 95% confidence interval 1.2–6.5) for adolescent migraine without aura, but no increased risk for migraine with aura (0.8, 0.3–2.2). Discussion and conclusions Infantile colic seems to be associated with an increased risk for migraine without aura, but not for migraine with aura. Whether infantile colic per se is a type of infantile migraine or an antecedent of future migraine remains to be answered by further research.
How I treat hemophagocytic lymphohistiocytosis in the adult patient
Authors: Schram Alison M. , Berliner Nancy 
Published: March 2015

Abstract
Hemophagocytic lymphohistiocytosis (HLH) is a devastating disorder of uncontrolled immune activation characterized by clinical and laboratory evidence of extreme inflammation. This syndrome can be caused by genetic mutations affecting cytotoxic function (familial HLH) or be secondary to infectious, rheumatologic, malignant, or metabolic conditions (acquired HLH). Prompt recognition is paramount and, without early treatment, this disorder is frequently fatal. Although HLH is well described in the pediatric population, less is known about the appropriate work-up and treatment in adults. Here, we review the clinical characteristics, diagnosis, and treatment of HLH in adults.

Purpose Although hematopoietic stem-cell transplantation is widely performed in children with high-risk acute lymphoblastic leukemia (ALL), the influence of donor types is poorly understood. Thus, transplantation outcomes were compared in the prospective multinational Berlin-Frankfurt-Muenster (BFM) study group trial: ALL-SCT-BFM 2003 (Allogeneic Stem Cell Transplantation in Children and Adolescents with Acute Lymphoblastic Leukemia). Patients and Methods After conditioning with total-body irradiation and etoposide, 411 children with high-risk ALL received highly standardized stem-cell transplantations during the first or later remissions. Depending on donor availability, grafts originated from HLA-genoidentical siblings or from HLA-matched unrelated donors who were identified and matched by high-resolution allelic typing and were compatible in at least 9 of 10 HLA loci. Results Four-year event-free survival (± standard deviation [SD]) did not differ between patients with transplantations from unrelated or sibling donors (0.67 ± 0.03 v 0.71 ± 0.05; P = .405), with cumulative incidences of nonrelapse mortality (± SD) of 0.10 ± 0.02 and 0.03 ± 0.02 (P = .017) and relapse rates (± SD) of 0.22 ± 0.02 and 0.24 ± 0.04 (P = .732), respectively. Among recipients of transplantations from unrelated donors, no significant differences in event-free survival, overall survival, or nonrelapse mortality were observed between 9/10 and 10/10 matched grafts or between peripheral blood stem cells and bone marrow. The absence of chronic graft-versus-host disease had no effect on event-free survival. Engraftment was faster after bone marrow transplantation from siblings and was associated with fewer severe infections and pulmonary complications. Conclusion Outcome among high-risk pediatric patients with ALL after hematopoietic stem-cell transplantation was not affected by donor type. Standardized myeloablative conditioning produced a low incidence of treatment-related mortality and effective control of leukemia.
Stability of solitary-wave solutions of coupled NLS equations with power-type nonlinearities
Authors: Bhattarai Santosh 
Published: March 2015

Abstract
This paper proves existence and stability of solitary-wave solutions of a
system of 2-coupled nonlinear Schrödinger equations
with power-type nonlinearities arising in several models of modern physics.
The existence of vector solitary-wave solutions (i.e., both components are nonzero)
is established via variational methods.
The set of minimizers is shown to be stable and further
information about the structures of this set are given.
The results extend stability results previously obtained by Cipolatti and Zumpichiatti [Nonlinear Anal. 42 (2000), 445–461], Nguyen and
Wang [Adv. Differential Equations 16 (2011), no. 9–10, 977–1000; `Existence and
stability of a two-parameter family of solitary waves for a 2-coupled nonlinear Schrödinger system', preprint (2013)], and Ohta [Nonlinear Anal. 26 (1996), 933–939].

Segmented independent component analysis for improved separation of fetal cardiac signals from nonstationary fetal magnetocardiograms
Authors: Murta Luiz O. , Guzo Mauro G. , Moraes Eder R. , Baffa Oswaldo , Wakai Ronald T. , Comani Silvia 
Published: March 2015

AbstractFetal magnetocardiograms (fMCGs) have been successfully processed with independent component analysis (ICA) to separate the fetal cardiac signals, but ICA effectiveness can be limited by signal nonstationarities due to fetal movements. We propose an ICA-based method to improve the quality of fetal signals separated from fMCG affected by fetal movements. This technique (SegICA) includes a procedure to detect signal nonstationarities, according to which the fMCG recordings are divided in stationary segments that are then processed with ICA. The first and second statistical moments and the signal polarity reversal were used at different threshold levels to detect signal transients. SegICA effectiveness was assessed in two fMCG datasets (with and without fetal movements) by comparing the signal-to-noise ratio (SNR) of the signals extracted with ICA and with SegICA. Results showed that the SNR of fetal signals affected by fetal movements improved with SegICA, whereas the SNR gain was negligible elsewhere. The best measure to detect signal nonstationarities of physiological origin was signal polarity reversal at threshold level 0.9. The first statistical moment also provided good results at threshold level 0.6. SegICA seems a promising method to separate fetal cardiac signals of improved quality from nonstationary fMCG recordings affected by fetal movements.
The hyperbolicity of the sphere complex via surgery paths

Abstract
In [10], Handel and Mosher have proved that the free splitting complex

{\mathcal{F\kern-2.27622ptS}_{n}}

for the free group

F

ℱ
⁢

𝒮
n

{\mathcal{F\kern-2.27622ptS}_{n}}

as a good analogue of the curve complex for surfaces.
We give a shorter alternative proof of this theorem, using surgery paths in Hatcher’s sphere complex (another model for the free splitting complex), instead of Handel and Mosher’s fold paths. As a byproduct, we get that surgery paths are unparameterized quasi-geodesics in the sphere complex.
We explain how to deduce from our proof the hyperbolicity of the free factor complex and the arc complex of a surface with boundary.
Thermoelectric Power Supply of Wireless Sensor Nodes in Marine Gearboxes
Authors: Schirrmacher Sebastian , Ullmann Georg , Overmeyer Ludger 
Published: March 2015

Abstract
This article presents a solution for the thermoelectric power supply of wireless sensor nodes for condition monitoring of marine gearboxes. Among the different ambient energy sources in marine gearboxes, frictional heat has been identified to be appropriate to thermally power a thermoelectric generator (TEG). The such generated electricity may power wireless sensor nodes for detecting temperature, vibration, torque and rotational speed. Requirements for a corresponding energy supply are formulated, constructive solutions are presented and thermal simulations and practical experiments are reviewed. The results are evaluated and a solution is selected for further implementation, which provides for an actively cooled TEG in the area of the ship gearbox’s heat exchanger. This can provide continuous electrical power of up to 14 mW, thus supplying the planned sensor nodes. The disadvantage of this solution is that a comparatively extensive mechanical modification, for example, to the oil and cooling water pipelines is required.
Response of Sunflower to Rainwater Conservation and Nutrient Management in Semi-arid Conditions
Authors: Patil S. L. , Mishra P. K. , Ramesha M. N. , Math S. K. N. 
Published: March 2015

AbstractSunflower is an important oilseed crop grown throughout the year due to its short duration, day neutral, low photoperiod sensitivity and wider adoptability to agroclimatic conditions and soil types in Asian countries. Lower yields of sunflower in rainfed vertisols are attributed to lower soil moisture and nutrients availability. In this situation, we conducted field studies at research farm and farmers’ fields to know the response of sunflower to rainwater conservation and nutrient management in vertisols of India. Compartmental bunding and ridges and furrows conserved more rainwater in profile, thus producing greater sunflower seed yields varying from 22% to 28% compared to farmers’ practice of flat-bed sowing. Greater seed yield with resource conservation is attributed to higher head diameter with greater head weight and seed weight per plant over flat-bed sowing. Nutrient management as farmers practice INM1(15 kg N ha−1+ 15 kg P2O5ha−1+ 1.0 t farmyard manure ha−1) withAzospirillumseed treatment (INM2) produced 5–6% higher seed yield, whereas recommended rate of nutrients (40 kg N ha−1+ 40 kg P2O5ha−1+ 2.0 t farmyard manure ha−1) withAzospirillumseed treatment (INM3) produced 13–16% greater seed yield both at research farm and farmers’ fields over INM1.
Further notes on sociolinguistic scales
Authors: Blommaert Jan , Westinen Elina , Leppänen Sirpa 
Published: March 2015

AbstractThis short paper seeks to reformulate and refine the notion of sociolinguistic scales as relative scope of understandability, thus drawing the notion fully into the realm of semiotics, rather than in the rather unproductive sphere of spatiotemporal and distributional interpretation where it has been deployed. Differences in scope of understandability are differences in the presupposability of signs, and such differences are not equivalent but stratified in a polycentric environment. Scales, in that sense, point towards the non-unified and hierarchical-layered nature of the sign and of meaning making practices. Scalar effects, once established, can furthermore be carried over into different indexical orders deployed on different topics. We draw on the results of a recent study of hip-hop culture in Finland to establish these points.
Longer nilpotent series for classical unipotent subgroups
Authors: Maglione Joshua

In studying nilpotent groups, the lower central series and other variations can be used to construct an associated ℤ+-graded Lie ring, which is a powerful method to inspect a group. Indeed, the process can be generalized substantially by introducing ℕ
d
-graded Lie rings.
We compute the adjoint refinements of the lower central series of the unipotent subgroups of the classical Chevalley groups over the field ℤ/pℤ of rank d. We prove that, for all the classical types, this characteristic filter is a series of length Θ(d

A Collaborative Workflow for Computer-Aided Design in Ambient Assisted Living: The ASIM Project
Authors: Ferry Nicolas , Berruet Pascal , Allegre Willy , Augu Laurent 
Published: March 2015

AbstractIn 2014, the worldwide context is that the population is increasingly both expanding and aging in industrial countries. In contrast, the personal health levels of individuals could decrease. Although retirement homes and health-care centers assume most of the demand, they will most probably overflow in the next few years. One of the current solutions is e-Health, which involves biomedical monitoring but also home automation functions to compensate for disabilities that tend to increase with age. In this context, several domains have to be merged while respecting the entire ecosystem: the users, their needs and environment, but also all the various actors/experts involved in this process. The issue, however, is that enormous effort is required to combine the multiple expert domains because these can be antinomic. Hence, this paper proposes a collaborative workflow that brings together these different actors and generates the control/command application. Applying model-driven engineering, this workflow makes a clear distinction between people’s health requirements, the home automation functions, and the user interface points of view. Thus, it allows experts in each field to adapt their system in terms of the user’s needs, disability, and health state.
Autonomous Evolution of Digital Art Using Genetic Algorithms
Authors: House Amanda , Agah Arvin 
Published: March 2015

AbstractThis paper applies a genetic algorithm (GA) to the autonomous evolution of digital art, eliminating the need for a human in the loop. Creative applications of GAs face the challenge of producing art or music to fit a wide range of human tastes. One approach is to use a human in the loop to determine the fitness function in order to direct the selection and evolution. Another approach, which this paper explores, is to define an objective fitness function to automate evolution without the need for human input. In this paper, several features of digital art are identified and used as the basis for fitness functions. The resulting images are recognizable for the intended evolution of the fitness function used. This indicates the potential of an approach to create more robust algorithmic fitness functions capable of evolving creative applications autonomously.

Über das Rauschen von Germanium-Einkristallen
Authors: Sautter D. , Seiler K. 
Published: March 2015

Es wird das Rauschen von Germanium-Einkristallen in Abhängigkeit von Feldstärke, Temperatur, Frequenz und Dotierung gemessen. Der Frequenzbereich liegt dabei zwischen 2 und 150 kHz, der Temperaturbereich zwischen 20 und 140°C, also im Übergangsbereich zwischen Stör- und Eigenleitung. Die Kristalle sind p- und n-leitend dotiert und haben spezifische Widerstände zwischen 0,3 und 60 Ωcm bei Zimmertemperatur.
Das mittlere Rauschstromquadrat ii
2 nimmt quadratisch mit der Feldstärke im Kristall zu, es steigt etwa exponentiell mit wachsender Temperatur an. Die Abhängigkeit von der Frequenz ƒ läßt sich teilweise durch Funktionen der Form i̅i
2 ∾ 1/[1+ (2 π ƒ τ)2] beschreiben. Die Temperatur- und Frequenzkurven sind dotierungsabhängig. Ein Vergleich der Meßergebnisse mit den bestehenden Theorien über das Schrotrauschen in Halbleitern läßt vermuten, daß der gemessene Rauschstrom durch Schwankungen der Konzentrationen der Ladungsträger bei der Bildung von Elektronen-Löcherpaaren erzeugt wird.
Zur Analyse des Zeitsinnes bei Periplaneta americana
Authors: Bünning Erwin 
Published: March 2015

The running activity was used as a measure of the course of the endogenous diurnal periodicity in Periplaneta americana. The influence of low temperatures (+5°, +3°, -2°), which acted on the diurnal cycle at different times was tested. In one of the two half cycles the delay of the internal clock due to the chilling was smaller or equal to the duration of the chilling. During this phase, at least at temperatures greater than zero, a minimum time of chilling was necessary in order to demonstrate the delay clearly. In the other half cycle the delay is greater than the duration of the chilling.
It is concluded that oscillations of relaxation are the basis of these phenomena. The phase of tension requires a minimum temperature. Below this minimum a gradual relaxation occurs. The phase of relaxation continues at low temperatures, but after some time it is gradually delayed.
The normal 24-hour light-dark cycle regulates these oscillations in such a way that the phase of tension begins in the second half of the light phase and it attains its maximum in the first part of the dark phase.
Untersuchungen über Aggregatbildung und Inaktivierung des Virus der Maul- und Klauenseuche
Authors: Zimmermann Th. 
Published: March 2015

„Eingefäß-verdünnte“ Lössungen des Virus der Maul- und Klauenseuche von +4° C zeigten im Laufe ihrer Lagerung Infektiositäts-Schwankungen von 0,60-0,85 log, die eine Frequenz von ca. 4 Tagen hatten.
In ruhig aufbewahrten Viruslösungen von +4° C, die vor der Probeentnahme zur Titration nicht durchmischt wurden, war das Virus gleichmäßig verteilt. Ein Durchmischen der Lösungen bewirkte in periodischem Wechsel eine Titererhöhung bzw. Erniedrigung im Sinne einer vermehrten Aggregation bzw. Desaggregation von Virus.
Die Volumenabhängigkeit der Infektiositäts-Abnahme von MKS-Viruslösungen wird durch mindestens zwei Faktoren verursacht. Sie wird einmal bedingt durch eine relativ größere Oberflächenreaktion bei Lösungen mit kleineren Volumen, zum anderen aber durch weitere noch unbekannte Faktoren. Bei Virus-Inaktivierungs-Versuchen mit Testlösungen von mindestens 100,0 cm3 ist die Volumenabhängigkeit der Infektiositäts-Abnahme von geringerem Einfluß auf die Ergebnisse.

Published: March 2015

Di-cyclopentadienyl-molybdän-di-hydrid (C6H5)2MoH2 und Di-cyclopentadienyl-wolfram-di-hydrid (C5H5)2WH2 lassen sich durch Umsetzung von MoCl5 und WCl6 mit NaC5H5 in großem Überschuß in Tetrahydrofuran und nachfolgende Sublimation erhalten. Die durch Lösen in Säuren nach
(C5H5)2MeH2 + Η⊕ → (C5H5)2MeH3⊕
komplex sich bildenden gelben Kationen (C5H5) 2MoH3⊕ und (C5H5)2WH3,⊕ bilden mit Laugen z. T. wieder die freien Hydride zurück und können daher zu deren Reinigung verwendet werden. Der Diamagnetismus derselben entspricht Edelgas-Konfigurationen, die durch Einbeziehung der Gesamtheit aller Ring-n-Elektronen und jeweils zwei an die Metalle gebundene H-Atome zustande kommen. IR-spektroskopische Befunde bestätigen diese Vorstellung. Dipolmessungen an (C5H5)2WH2 in Benzol beweisen einen unsymmetrischen Bau mit vermutlich schräg gestellten, jedoch noch zentrisch gebundenen Ringen.

1. UV-Bestrahlung unter Luft bzw. Argon führt zum Verschwinden der charakteristischen UV-Absorption des Benzpyrens. Chromatographisch entsteht eine Reihe von Reaktionsprodukten, die sich aber bei beiden Gasphasen unterscheiden.
2. Wird eine reine Benzpyren-Cyclohexanlösung bis zu 5 Mill. r röntgenbestrahlt, so sind keine Veränderungen festzustellen. Bei Anwesenheit von Wasser in Form einer entsprechenden Emulsion kommt es dagegen ebenfalls zum Verschwinden der charakteristischen Absorption im UV und zum Auftreten neuer Reaktionsprodukte im Chromatogramm.
Fermentpolymerisation VI
Authors: H. Ebert Von , Stricker H. 
Published: March 2015

The action of levan sucrase from aerobacter levanicum on sucrose can be divided into three reactions: levan formation, inversion and oligosaccharide formation. As in dextran synthesis, levan has extremely high molecular weights which are formed even at very small conversions. The oligosaccharides consist mainly of 1β-fructosyl sucrose.
From kinetic data of reactions with enzyme preparations which have been prepared on sucrose containing cultivation media, we could conclude that a levanase was present in our enzyme preparations. By application of fructose instead of sucrose in our cultivation media we could get enzyme preparations completely free of levanase and levan. Temperature- and pH-stability measurements and kinetic data lead to the conclusion that all three reactions are catalysed by the same enzyme. This was confirmed by investigations in the ultracentrifuge; the molecular weight of the enzyme as measured by sedimentation analysis was found to be 22 000.
