Relative Fundamental Frequency in Children With and Without Vocal Fold Nodules
Authors: Heller Murray Elizabeth S. , Segina Roxanne K. , Woodnorth Geralyn Harvey , Stepp Cara E. 
Published: February 2020

Purpose
Relative fundamental frequency (RFF) is an acoustic measure that is sensitive to functional voice differences in adults. The aim of the current study was to evaluate RFF in children, as there are known structural and functional differences between the pediatric and adult vocal mechanisms.

Method

RFF was analyzed in 28 children with vocal fold nodules (CwVN,
M
= 9.0 years) and 28 children with typical voices (CwTV,
M
= 8.9 years). RFF is the instantaneous fundamental frequency (
f
0
) of the 10 vocalic cycles during devoicing (vocal offset) and 10 vocalic cycles during the revoicing (vocal onset) of the vowels that surround a voiceless consonant. Each cycle's
f
0
was normalized to a steady-state portion of the vowel. RFF values for the cycles closest to the voiceless consonant, that is, Offset Cycle 10 and Onset Cycle 1, were examined.

Results
Average RFF values for Offset Cycle 10 and Onset Cycle 1 did not differ between CwVN and CwTV; however, within-subject variability of Offset Cycle 10 was decreased in CwVN. Across both groups, male children had lower Offset Cycle 10 RFF values as compared to female children. Additionally, Onset Cycle 1 values were decreased in younger children as compared to those of older children.

Conclusions

Unlike previous work with adults, CwVN did not have significantly different RFF values than CwTV. Younger children had lower RFF values for Onset Cycle 1 than older children, suggesting that vocal onset
f
0
may provide information on the maturity of the laryngeal motor system.

Published: February 2020

PurposeThis article describes the iterative development of a home review program designed to augment vocabulary instruction for young children (ages 4 and 5 years) occurring at school through the use of a home review component.MethodA pilot study followed by two experiments used adapted alternating treatment designs to compare the learning of academic words taught at school to words taught at school and reviewed at home. At school, children in small groups were taught academic words embedded in prerecorded storybooks for 6 weeks. Children were given materials such as stickers with review prompts (e.g., “Tell me whatbravemeans”) to take home for half the words. Across iterations of the home intervention, the home review component was enhanced by promoting parent engagement and buy-in through in-person training, video modeling, and daily text message reminders. Visual analyses of single-subject graphs, multilevel modeling, and social validity measures were used to evaluate the additive effects and feasibility of the home review component.ResultsSocial validity results informed each iteration of the home program. The effects of the home program across sites were mixed, with only one site showing consistently strong effects. Superior learning was evident in the school + home review condition for families that reviewed words frequently at home. Although the home review program was effective in improving the vocabulary skills of many children, some families had considerable difficulty practicing vocabulary words.ConclusionThese studies highlight the importance of using social validity measures to inform iterative development of home interventions that promote feasible strategies for enhancing the home language environment. Further research is needed to identify strategies that stimulate facilitators and overcome barriers to implementation, especially in high-stress homes, to enrich the home language environments of more families.
Constraining the redshifts of unlocalised fast radio bursts
Authors: Walker Charles R. H. , Ma Yin-Zhe , Breton René P. 
Published: February 2020

Context. The relationship between the dispersion measures (DMs) and redshifts of fast radio bursts (FRBs) is of scientific interest. Upcoming commensal surveys may detect and localise many FRBs to the sub-arcsecond angular resolutions required for accurate redshift determination. Meanwhile, it is important to exploit sources accumulated with more limited localisation to their maximum scientific potential.
Aims. We present techniques for the DM-redshift analysis of large numbers of unlocalised FRBs, accounting for uncertainties due to their extragalactic DM components, redshift dependences, and progenitor scenarios.
Methods. We reviewed the components comprising observed FRB DMs. We built redshift-scalable probability distribution functions for these components, which we combined in cases of multiple progenitor scenarios. Accounting for prior FRB redshift distributions we inverted these models, enabling FRB redshifts to be constrained.
Results. We illustrate the influence of FRB progenitors on their observed DMs, which may remain significant to redshift z ~ 3. We identify the FRB sample sizes required to distinguish between multiple progenitor scenarios. We place new, physically motivated redshift constraints on all catalogued FRBs to date and use these to reject potential host galaxies in the localisation area of an FRB according to various models. We identify further uses for DM-redshift analysis using many FRBs. We provide our code so that these techniques may be employed using increasingly realistic models as our understanding of FRBs evolves.
Impact of climate change on pavements
Authors: Hemed Ahmed , Ouadif Latifa , Bahi Lahcen , Lahmili Abdelaziz 
Published: February 2020

Climate change is reflected in changes in average weather conditions and the more frequent occurrence of extreme conditions. It also affects the field of road transport and shows impacts both on traffic and road users as well as on the road infrastructure itself.
The main objective of this work is therefore to evaluate the impact of climate change on the performance of road infrastructure (pavements) and to educe recommendations through proposals for adaptation measures.
The impacts of climate change on road infrastructure result in changes in some road design parameters (average temperatures, radiation index, etc.).
The different cases of cracking (fatigue or other) are assessed separately using degradation indices for each layer composing a pavement (surface layer, base layer, stabilized layer, etc.)

The aim of this work is to verify the technical feasibility of composting in the case of Marrakech prefecture. On the basis of waste composition and in accordance with the choice of the installation of Marrakech controlled landfill, composting has been considered as the most suitable waste treatment.To ensure the feasibility of composting, physicochemical analyses have been carried out on the fermentable part of waste; analyses on the content of metal elements have also been performed on the fine fraction, since the most important part is located in the same fraction. All parameters determined in the laboratory, have shown that optimal conditions to have good quality compost have been respected. The only restriction identified is the copper content, which should be less than 20 ppm. Generally the low levels of metal element content indicate that the storage and collection conditions of waste have not influenced their quality. On the other hand, the process must be properly controlled and managed, to produce high-quality compost.

Published: February 2020

The watershed Ouergha River located in the north of Morocco suffer from vegetation cover degradation, this geographic entity is experiencing intense water erosion linked to the combination of several natural factors, such as the roughness and abundance of rainfall and the predominance of soft geological formations. Human intervention in this vulnerable environment accentuates its fragility by the clearing and degradation of the vegetation cover and the cultivation of land with a steep slope.
This work aims to map the spatiotemporal evolution of this degradation by using the spot and Landsat images and the Radar image over a period from 1990 to 2014 data and aims to model its processes of erosion.
In fact, the analysis of satellite data identified six main types of land use (eau, foret, reboisement…). It has also shown that the most degraded soils aren’t necessarily those with the greatest erosion rates over the past 15 years and that some soils that have developed well over time have become major exporters of sediments after clearing and cultivation.
The comparison of the results of land use has highlighted the harmful impact of human practices on the acceleration of soil degradation.
Human intervention, coupled to frequent and severe drought periods, remain the most important factors in the weakening and increasing vulnerability of soils to degradation.
The results obtained by this approach made it possible to identify and monitor vulnerable areas at Ouergha watershed where interventions are needed to limit the processes of degradation of the soil and the natural environment.

Chaos im Hormonhaushalt – wie Rhythmische Hormontherapie beim Tier helfen kann
Authors: Schindhelm Katja 
Published: February 2020

ZusammenfassungChronische Entgleisungen des Hormonhaushalts beruhen zumeist auf einer Schwäche der Hypophyse, in deren Folge die untergeordneten endokrinen Drüsen weniger Hormone produzieren und ausschütten. Ziel der Rhythmischen Hormontherapie ist, durch alternierende Anwendung endokriner Komplexmittel die Drüsen wieder zu vermehrter Tätigkeit zu stimulieren, statt die fehlenden Hormone zu substituieren. Gleichzeitig soll das gestörte Gleichgewicht der Chakren behoben werden. Somit schlägt die Rhythmische Hormontherapie eine Brücke zwischen der körperlichen und energetischen Behandlung. Sie ist kompatibel zu allen anderen Therapieformen und kann deshalb als regulative Basistherapie eingesetzt werden.
Konzentration von Spurenelementen beim Rind in verschiedenen Probenmedien unter besonderer Berücksichtigung von Kotproben
Authors: Herold Andrea , Müller Anja-Elvira , Staufenbiel Rudolf , Pieper Laura 
Published: February 2020

Zusammenfassung
Gegenstand und Ziel Zur Beurteilung der Spurenelementversorgung sollte die Eignung und Aussagekraft von Kot als Untersuchungsmedium getestet werden.
Überprüft wurde, ob die Konzentration der Spurenelemente Eisen, Kupfer, Zink, Selen, Mangan und Molybdän im Kot das Angebot im Futter widerspiegelt und ob die
Kotanalyse Informationen über den Versorgungsstatus im Organismus liefert. Hierfür erfolgte ein Vergleich der Konzentrationen im Futter und in den Substraten
Kot, Serum, Plasma, Vollblut, Harn sowie Haar.
Material und Methoden Bei 73 Bestandsuntersuchungen in 63 Milchviehbetrieben wurde von jeweils bis zu 10 Kühen aus der Vorbereiter- (3–0 Wochen a. p.) und
Hochleistungsgruppe (6–20 Wochen p. p.) Probenmaterial (Kot, Blut, Harn, Deckhaar) gewonnen und jeweils eine Probe der totalen Mischration (TMR) entnommen. Die
Konzentration der Spurenelemente wurde in den gepoolten Proben der beiden Laktationsgruppen und in den TMP-Proben mittels ICP-OES- bzw. ICP-MS-Methode
analysiert. Ergänzend wurden Kotproben aus 5 Mutterkuhherden während der Weide- sowie Stallsaison untersucht.
Ergebnisse Die Spurenelementkonzentrationen im Futter überschritten mehrheitlich die Bedarfswerte. Die Konzentrationen im Kot lagen 2- bis 3-fach höher
als die im Futter. Kot- und TMR-Gehalte zeigten stets die stärkste signifikante Korrelation zueinander. Saisonale Abweichungen wurden bei Eisen, Kupfer und
Mangan beobachtet. Laktationsbedingte Abweichungen ergaben sich bei Eisen.
Schlussfolgerung und klinische Relevanz Die Untersuchung von Kot lässt bei allen überprüften Spurenelementen eine gute Einschätzung der nutritiven
Versorgungssituation zu. Eine Anwendung in der Praxis bietet sich deshalb in Fällen an, in denen sich keine Einzelfuttermittel oder TMR analysieren lassen. Die
Bestimmung der Spurenelemente aus dem Kot kann deshalb bei Weidetieren, Färsen, Mutterkühen oder Stalltieren ohne TMR nützlich sein. Die metabolische
Versorgungslage wird durch die Kotanalyse ungenügend reflektiert. Allerdings können die Kotgehalte der Elemente Kupfer, Zink und Mangan auf eine inadäquate
metabolische Versorgungssituation hinweisen und Anlass für eine weiterführende Diagnostik sein.

Association of the Triglyceride to High-Density Lipoprotein Ratio and
the Visceral Adiposity Index with Metabolic Syndrome in Diabetic Susceptible
Population
Authors: Huang Wenli , Shu Linyi , Zhao Hang , Chen Sufeng , Zhang He , Song Guangyao 
Published: February 2020

AbstractThe aim of this study was to explore the association of the triglyceride to
high-density lipoprotein ratio (TG/HDL) and the visceral adiposity
index (VAI) with metabolic syndrome (Mets) in high-risk populations of
diabetic patients. Patients were recruited from the Endocrinology Clinic of
Hebei General Hospital from April 2018 to April 2019,according to the
“Guidelines for the Prevention and Treatment of Type 2 Diabetes in
China (2017 Edition)”. A total of 824 patients participated in the
study. The association between TG/HDL or VAI and Mets in these
patients was assessed using a multivariate logistic regression model.
Receiver operating characteristic (ROC) curve analysis was used to evaluate
the ability of TG/HDL and VAI to predict Mets in the diabetic
susceptible population. The prevalence of Mets gradually increased in males
and females with advancing tertiles of TG/HDL or VAI. After
adjusting for the relevant risk factors, TG/HDL and VAI were
positively correlated with Mets in men and women. Both of them showed a
better the area under the ROC curve (AUC) for Mets in females than body mass
index, waist circumference, TG and homeostatic model assessment of insulin
resistance. In females, the cut-off point of 1.67 for VAI showed a higher
accuracy for Mets (sensitivity 0.756, specificity 0.705, Youden index
0.461), the same relationship not significant in men. TG/HDL and VAI
provide a high predictive value for Mets in a diabetic susceptible
population, especially in females.
Reply to Drs. Kiaei and Molinaro Regarding the Publication
“Comparison of a Bridge Immunoassay with Two Bioassays for Thyrotropin Receptor
Antibody Detection and Differentiation”
Authors: Allelein Stephanie , Diana Tanja , Schott Matthias , Kahaly George J. 
Published: February 2020

Dear Editor,Drs. Kiaei and Molinaro 1 put forth two
criticisms of the manuscript published by us 2. They state that the experimental design of this study is flawed
and that the authors falsely claim that negative Thyretain™ TSI Reporter
BioAssay results for two Graves’ diseases patients undergoing drug
treatments means the absence of stimulating antibodies. To substantiate this
claim Drs. Kiaei and Molinaro point out that the manufacturer of the Thyretain
TSI Reporter BioAssay clearly states in the package insert that “[t]he
effects of various drug therapies on the performance of this Kit have not been
established” 1. Second, the
package insert explicitly states that “[a] negative result does not
exclude the possibility of the presence of TSI” and results of the test
should be interpreted in conjunction with information available from other
clinical information, such as physical symptoms and thyroid hormone testing, as
recommended by the American Thyroid Association (ATA)”. Furthermore they
state that the “authors of the manuscript did not consider the
manufacturer’s warning regarding the intended patient population and the
ATA guidelines regarding the interpretation of the test results in conjunction
with other clinical information. Instead, the authors based their conclusions on
the negative Thyretain TSI Reporter BioAssay results and ignored the
patients’ clinical history of Graves’ disease.”

Authors: Riechardt Silke , Fisch Margit 
Published: February 2020

ZusammenfassungDer Hodenhochstand stellt eine der häufigsten Erkrankungen im Kindesalter dar und wird bei 3 – 8 % der männlichen Patienten diagnostiziert. Das Ziel der Therapie des Hodenhochstandes ist der Deszensus in den Hodensack innerhalb des ersten Lebensjahres, um anhaltende degenerative Veränderungen des Hodens zu vermeiden. Oft ist dazu eine operative Behandlung notwendig.Die chirurgische Therapie des tastbaren Hodens im Bereich der Leiste ist die Orchidopexie und bei nicht tastbaren Hoden ein laparoskopischer Ansatz mit ggf. inguinaler Freilegung. Die Orchidopexie für einen tastbaren Hoden kann durch einen traditionellen Leistenschnitt (inguinal) oder transskrotal behandelt werden. Der inguinale Zugangsweg gilt für die Orchidopexie als operative Methode der Wahl.

Published: February 2020

AbstractMNEs shape the location of activities in the world economy, linking diverse regions in what has been called theglobal factory. This study portrays the evolution of incomes and employment in the global factory using a quantitative input–output approach. We find emerging economies forging ahead relative to advanced economies in income derived fromfabrication activities, handling the physical transformation process of goods. In contrast, convergence in income derived fromknowledge-intensive activitiescarried out in pre- and post-fabrication stages is much slower. We discuss possible barriers to catching-up and policy implications for emerging economies in developing innovation capabilities, stressing the pivotal role of MNEs.
Predictors of second language English lexical recognition
Authors: Skalicky Stephen , Crossley Scott A. , Berger Cynthia M. 
Published: February 2020

Abstract
In this study we analyze a large database of lexical decision times for English content words made by speakers of
English as an additional language residing in the United States. Our first goal was to test whether the use of statistical
measures better able to model variation associated with participants and items would replicate findings of a previous analysis of
this data (Berger, Crossley, & Skalicky, 2019). Our second goal was to determine
whether variables related to experiences using and learning English would interact with linguistic features of the target words.
Results from our statistical analysis suggest affirmative answers to both of these questions. First, our results included
significant effects for linguistic features related to contextual diversity and contextual distinctiveness, providing a
replication of findings from the original study in that words appearing in more textual and lexical contexts were responded to
quicker. Second, a measure of length of English learning and a measure of daily English use interacted with a measure of
orthographic similarity. Our study provides further evidence regarding how a large, crowdsourced database can be used to obtain a
better understanding of second language lexical recognition behavior and provides suggestions for further research.
Formation of ultracold ion pairs through long-range Rydberg molecules
Authors: Peper Michael , Deiglmayr Johannes 
Published: February 2020

Abstract
We propose a new approach to excite ion-pair states of ultracold dimers. The central idea is a two-step process where first long-range Rydberg molecules are formed by photoassociation, which are then driven by stimulated emission towards the ion-pair state, a process bearing features of a photo-induced harpooning reaction. We assess the feasibility of this approach through a detailed experimental and theoretical study on a specific system, p-wave-scattering dominated long-range Rydberg molecules in caesium, and discuss potential applications for the study of strongly correlated plasmas consisting of oppositely charged particles of equal or similar mass.
Durability of fiber boards made of jabon and andong bamboo with additional activated carbon additives against dry wood termites and subterranean termites

Published: February 2020

Abstract
Utilization of wood waste as material to produce medium density fiber-board (MDF) will help to reduce the rate of deforestation. Jabon waste (Anthocephalus cadamba Miq.) combined with andong (Gigantochloa pseudoarundinacea (Steudel) Widjaja) bamboo waste with 50%:50% ratio were made into MDF with the size of 30 cm x 30 cm x 1.2 cm and density 0.45 kg/m3 and 0.55 kg/m3. Activated carbon additive 4% were then added in the process. MDF durability test towards attack from Cryptotermes cynocephalus Light dry wood termite and Coptotermes curvignathus Holmgrem subterranean termites were done according to SNI 01-7207-2014. Result shows that the addition of activated carbon powder increased the MDF’s dry wood termites-durability level from IV (not-durable) to III (moderately durable). Meanwhile, adding activated carbon powder additive in MDF had not increase its durability to subterranean termites attack. The MDF durability level against soil termite stood at the same level of IV (not-durable). Improvement needs to be done for MDF made of jabon and andong bamboo mix using preservatives to increase the MDF durability level.
