Joint Standard German and Bavarian Subdialect Identiﬁcation of Broadcast Speech

Automatic speech recognition is a very important technique for numerous applications like automatic subti-tling, dialogue systems and information retrieval systems. Speech recognition systems usually perform very well in clean and controlled environments. However they still often fail when mismatches between the trained models and the testing data are present, e.g. due to noise, re-verberation, or dialects. A method to cope with dialects is to identify the dialect in advance and then use specialized dialectal speech recognition models for the decoding. Also, dialect identiﬁcation systems have recently been used for targeted advertising, service customization, forensics tasks and for text-to-speech synthesis of regional speech. In this work, we annotate a large quantity of dialectal and standard German speech from a German broadcaster and exploit the data to train and evaluate a joint standard German and Bavarian subdialect identiﬁ-cation system that is able to distinguish between standard German and three Bavarian subdialects, namely Bavarian, Swabian and Franconian, with promising performance.
Magnetic quantum phase transitions of the antiferromagnetic J1-J2 Heisenberg model

We obtain the complete phase diagram of the antiferromagnetic J1-J2 model, 0 ≤ α = J2/J1 ≤ 1, within the framework of the O(N) nonlinear sigma model. We find two magnetically ordered phases, one with Néel order, for α ≤ 0.4, and another with collinear order, for α ≥ 0.6, separated by a nonmagnetic region, for 0.4 ≤ α ≤ 0.6, where a gapped spin liquid is found. The transition at α = 0.4 is of the second order while the one at α = 0.6 is of the first order and the spin gaps cross at α = 0.5. Our results are exact at N →∞ and agree with numerical results from different methods.
Amplitudenvariation als neue sensorische Dimension in der akustischen Analytik

Verschleis und Reibung an Kontakten zwischen rauen Oberflachen (Multi- Kontakt-Grenzflachen) spielen in der Technik eine wichtige Rolle. An di esen Grenzflachen hat man es mit einer Vielzahl von Kontakten zu tun, welche nicht elastisch unabhang ig voneinander sind und welc he weiterhin in Grose und Festigkeit variieren. Diese Komplikatione n machen die Untersuchung von Multi-Kontakt- Grenzflachen zu einer Herausforderung. Im Rahmen dieser Arbeit wurde die Schwingquarzmikrowaage (quartz crystal microbalance, QCM) als akustisches Messgerat fur tribologische sowie mikr ofluidische Untersuchungen genutzt. Der Fokus lag auf der Variation der Scheramplitude. Durch ei ne Weiterentwicklung des Messaufbaus konnte die Scheramplitude um das Funffache und die Normalkr aft bzw. der Druck um das Zehnfache gesteigert werden. Die betreffenden Entwicklungen ermogliche n Messungen auf verschiedenen Obertonen. Die auftretenden nicht-linearen Effekte konnten beobachte t und quantifiziert werden; Kontaktsteifigkeit und Reibungskoeffizient wurden bestim mt. Bezuglich des Reibungskoeffizienten wurden charakteristische Unterschiede zwischen Multi-Kont akt-Grenzflachen und Einzelkontakten gefunden. Fur Multi-Kontakt- Grenzflachen steigt der Reibungskoeffizient mit stei gender vertikaler Last, wahrend bei Einzelkontakten das gegenteilige Verhalten beobachtet wird. Der fur den Einzelkontakt schon bekannte Partial-S lip-Mechanismus unter oszillatorischer Belastung wurde auch bei Multi-Kontakt-Grenzflachen ge funden. Die verwendeten Testkorper waren aus Aluminium oder Kunststoff gefertigt und wiesen Raui gkeiten auf der Mikrometer-Skala auf. Unter kleinen Scherauslenkungen findet im Ra ndbereich eines Kontakts der soge nannte „Partial Slip“ statt. Die Scheramplitude kann solange erhoht werden, bis ein vollstandiges Abgleiten eintritt („Gross Slip“). Zusatzlich konnte an rauen Oberflachen ei n Reibverschleis aufgezeigt werden. In einem zweiten Teil der Arbeit konnte nachgewi esen werden, dass sich Quarzresonatoren in Flussigkeiten unter hohen Scheramplituden aufg rund der auftretenden Biegemoden als Pumpe verwenden lassen. Die stetige tangentiale Stromung ge ht auf den nicht-linearen Term der Navier-Stokes- Gleichung zuruck. Diese Stromung spielt vermutliche eine entscheidende Rolle bei den in der Literatur berichteten Ablosevorgangen von Bioa dsorbaten bei hohen Scheramplituden.
Understanding the career dynamics of IT professionals in digital transformation times: a systematic review of career anchors studies

The concept of career anchors has long been a reference model to guide Human Resources Management (HRM) practices within the information technology (IT) discipline. However, as the digital transformation phenomenon grows increasingly disruptive, the misalignment of human resources is becoming more apparent as IT professionals are faced with mixed job demands requiring multidisciplinary skillsets. Along with the lack of workforce diversity and high turnover rates, these HRM challenges are impacting career dynamics and talent management practices. A systematic literature review of 20 empirical studies reveals three broad themes: debunking the dual-ladder construct of traditionally opposing technical and management career paths, fostering a diverse workforce through a variety of demographic profiles, and understanding the response strategies of IT professionals. While career anchors proved to be a useful model, it falls short in the context of the current structural changes of professional career choices and talent requirements, which requires a more diverse and dynamic model. This finding leads to a new research agenda emphasizing the study of Business Technology Management (BTM). This new concept refers to an emerging transdisciplinary profession, uniting Project Management (PM), Information Systems (IS) and IT competencies within a common body of knowledge for leading digital transformation projects.
Simulated Preferential Water Flow and Solute Transport in Shrinking Soils

We present follow‐up work to previous work extending the classical rigid (RGD) approach formerly proposed by Gerke and van Genuchten, to account for shrinking effects (SHR) in modeling water flow and solute transport in dual‐permeability porous media. In this study we considered three SHR scenarios, assuming that aggregate shrinkage may change either: (i) the hydraulic properties of the two pore domains, (ii) their relative fractions, or (iii) both hydraulic properties and fractions of the two domains. The objective was to compare simulation results obtained under the RGD and the SHR assumptions to illustrate the impact of matrix volume changes on water storage, water fluxes, and solute concentrations during an infiltration process bringing an initially dry soil to saturation and a drainage process starting from an initially saturated soil. For an infiltration process, the simulated wetting front and the solute concentration propagation velocity, as well as the water fluxes and water and solute exchange rates, for the three SHR scenarios significantly deviated from the RGD. By contrast, relatively similar water content profiles evolved under all scenarios during drying. Overall, compared to the RGD approach, the effect of changing the hydraulic properties and the weight of the two domains according to the shrinkage behavior of the soil aggregates induced a much more rapid response in terms of water fluxes and solute travel times, as well as a larger and deeper water and solute transfer from the fractures to the matrix during wetting processes.
Evaluation of the influence of cetylamine fluoride and sodium fluoride on acid production by S. mutans

The acidogenic character of Streptococcus mutans has been pointed out as one of the most important physiological aspects associated with dental caries establishment. Fluoride is a key component of oral health promotion. Amine fluorides (AmF) have been used in products such as mouth rinses, toothpastes, gels and other topical fluoride agents for over 30 years in several European countries. In Brazil, the use of such substances was limited to toothpaste until August 2000, when a new resolution was published to approve the use of three AmFs in mouth rinses and other formulations for odontological purposes. In this report the influence of cetylamine fluoride (CAmF) and sodium fluoride (NaF) on acid production by S. mutans was evaluated and compared. An adapted Highperformance Liquid Chromatography (HPLC) method was employed for the analysis of intraand extra cellular final metabolic products in cell samples of S. mutans previously treated with both CAmF and NaF solutions. The analyses show that CAmF presents a higher inhibitory effect on the bacterial acidogenic potential when compared to NaF at equimolar fluoride concentrations and support the introduction of mouth rinses and other topical fluoride agents containing CAmF in the Brazilian Cosmetic Market as an alternative source of fluoride. *Correspondence:
Discovering collocations via data-driven learning in L2 writing

Adopting the approaches of pattern hunting and pattern refining (Kennedy & Miceli, 2001, 2010, 2017), this study investigates how seven freshman English students from Taiwan used the Corpus of Contemporary American English to discover collocation patterns for 30 near-synonymous change-of-state verbs and new ideas about the topic of “change” in the drafting stage of their essay writing. The study used a mixedmethods approach to examine the learning outcomes, learners’ corpus use, and their perceptions of the process. Results were drawn by analyzing writings in three time frames (pre-test, post-test, delayed posttest), video files of corpus consultation, questionnaires, and stimulus recall-session interviews. The results showed that the learners successfully discovered and incorporated collocation patterns in change-of-state verbs and ideas about the topic of change into their essays, although some difficulties emerged. Their performance on change-of-state verbs improved, and this improvement remained three months after the treatment. The study also demonstrated learners’ different perceptions and actualizations of the affordances offered by the corpus. While all learners used the corpus to correct collocation errors, they had diverse attitudes and uses of the corpus to address content ideas or collocation complexities in their writing. The study concludes by discussing the theoretical and pedagogical implications of the results.
Concurrently Produce a Novel High-Potency Sweetener (Glycyrrhetic Acid 3-O-Mono-β-D-glucuronide) and Lignocellulolytic Enzymes using Plant Entophytic Chaetomium Globosum DX-THS3 by Solid-State Fermentation

Licorice straw was used for the first time as a medium for glycyrrhetic acid 3-O-mono-β-D-glucuronide (GAMG) and lignocellulosic enzyme production via solid-state fermentation (SSF) of endophytic fungus Chaetomium globosum DX-THS3. Under optimal fermentation conditions, the percent conversion of glycyrrhizin reached 90% in 15 days, whereas the control needed 35 days to achieve the same result. The productivity of optimization (P=2.1 mg•g-1•day-1) was 2.33-fold that of non-optimization (P=0.9 mg•g-1•day-1). Meanwhile, high activities of filter paper enzyme (FPase) (234.6 U/g), carboxymethyl cellulase (CMCase) (29.25 U/g), xylanase (72.52 U/g), and β-glucuronidase activity (264.17 U/g) were obtained faster than those in the control during SSF. Our study provides a novel and efficient strategy for GAMG production and indicates C. globosum DX-THS3 as a potential producer of lignocellulolytic enzymes.

Director diversity and inclusion: At the table but in the game?

The issue of the presence of diverse directors on boards has attracted considerable attention among policymakers, practitioners, and academics. There is relatively less attention to the inclusion of diverse directors, or their onward tra-jectory after appointment. We study two outcomes related to inclusion—the retention of directors and their promotion to board leadership positions. Although gender is a key focus of many diversity discussions, we find significant inclusion results on skill diversity andnongenderdiversity dimensions. Retention and promotion are “less” likely for age-and ethnicity-diverse directors but both outcomes are more likely for skill-diverse directors.
Pachamanka: Inka Earthen Ovens from Tambo Viejo, Peru

Early Spaniards reported that the Inka state organized public celebrations involving extravagant banquets and drinking, in addition to singing and dancing. Cieza de León and Cobo noted that large number of llamas were slaughtered for such special celebrations. Although it is understood that food was an integral part of the festivities and that the Inka state used food as a political tool, until recently the meal preparation details for such large gatherings remained unknown. Recent archaeological excavation at Tambo Viejo revealed the presence of earthen ovens, similar in fashion to contemporary pachamanka, that were used for cooking at Inka state public celebrations.
An Analysis of the Informational Value of Sovereign Credit Ratings

The sovereign credit ratings (SCRs) have been an integral part in the global financial system in asset allocation and price discovery. The zero bound policy rate (ZBPR) and quantitative easing programme (QEP) rolled out by the four key central banks as antidotes to the global financial crisis (GFC) would have altered the assumed premise on SCRs relevancy. This preliminary study is crafted for a validation on whether the SCRs informational value on sovereign bond yields (SBYs) and sovereign credit default swap spreads (SCDSSs) was indeed affected when ZBPR and QEP were in effect. A sample of 32 countries with observations spanning from 2008 to 2017 to encompass the period of ZBPR and QEP in effect was used for analysis. The empirical results show that SCRs informational value was indeed rendered irrelevant on SBYs price discovery since 2008 and the effect on SCDSSs came in later from 2012 onwards.
The Analysis of lncRNA-miRNA-mRNA Competitive Endogenous RNA Network to Identify 4-lncRNA Signature Related to the Prognosis of Bladder Cancer

BackgroundBladder cancer (BLCA) is one of the leading causes of cancer deaths in the world, and the molecular mechanism of its pathogenesis is very complicated. Long non-coding RNA (lncRNA) can interact with microRNA (miRNA) through the mechanism of competitive endogenous RNA (ceRNA), and affect the expression of Messenger RNA (mRNA), and affect the pathogenesis of bladder cancer. This study aims to construct the ceRNA-regulated bladder cancer network related to lncRNA and identify a novel lncRNA signature related to the survival prognosis of patients with bladder cancer. It was validated in GEPIA's online bioinformatics network server assists. MethodsThe RNA sequencing data of normal and adjacent bladder cancer tissues are from the Cancer Genome Atlas (TCGA). We identify differentially expressed (DE) genes by comparing gene expression between normal tissues and tumors in the TCGA dataset. Construct a ceRNA network and explore potential biological markers. Based on the ceRNA network, univariate regression analysis and multivariate regression analysis were used to screen out the lncRNA related to the overall survival (OS) of bladder cancer. It was validated in GEPIA's online bioinformatics network server assists. Receiver operating characteristic curve (ROC) analysis was used to evaluate the prognostic value of the risk score.ResultsWe screened out 666 lncRNAs, 160 microRNAs (miRNAs), and 1,820 Messenger RNAs (mRNAs) by comparing normal bladder cancer tissues and adjacent tissues (P<0.05). Then, we constructed a ceRNA regulatory network containing 44 DElncRNA, 22 DEmiRNA, and 52 DEmRNA. The survival analysis of differential genes in the ceRNA network identified 9 lncRNAs, 8 miRNAs, and 12 mRNAs that are associated with the prognosis of BLCA. Cox regression analysis of 9 LncRNAs related to the prognosis of bladder cancer showed that 4 lncRNAs (AC078778.1, ADAMTS9-AS1, ADAMTS9-AS2, and NAV2-AS2) can be independently used as prognostic markers of bladder cancer.ConclusionsBased on the construction of the bladder cancer ceRNA network, a new prognostic signature of four lncRNA-based has been discovered. It will help to better understand the mechanism of bladder cancer occurrence, development and metastasis, and provide direction for future research.
A systematic review: The YouTube recommender system and pathways to problematic content

The systematic review aimed to determine whether the YouTube recommender system facilitates pathways to problematic content such as extremist or radicalising material. The review assessed the eligibility of 1187 studies and excluded studies using the PRISMA process for systematic reviews, leaving a final sample of 23 studies. Overall, 14 studies implicated the YouTube recommender system in facilitating problematic content pathways, 7 produced mixed results, and two did not implicate the recommender system in facilitating pathways to problematic content. Thus, the review's findings indicate that the YouTube recommender system could lead users to problematic content via the recommender system. The review indicates a need for corrections to the recommender system to shift users away from problematic content.
LTP­MS of PM2.5 filters sampled in dwellings - A new and simple fingerprinting method

In the present study PM2.5 filters are analyzed directly without sample preparation by use of Low Temperature Plasma Ionization (LTP), a new ambient ionization method for mass spectrometry (MS). This yields a fast method for screening and fingerprinting of the relative abundance of the dominating species as an alternative to extraction followed by HPLC-MS. Further ozone is sampled with passive samplers. Indoor and outdoor average air concentrations over the 4 day sampling campaigns are related to the differences in the fingerprinting.
Short‐term impact of beaver dam analogues on streambank erosion and deposition in Semi‐Arid landscapes of the Western USA

River systems in the mountain western USA have been shaped by the presence of beavers for millennia. However, beavers have been extirpated from the landscape in many places, leading to excessive stream incision and streambank erosion. One common strategy to mitigate this issue is to deploy beaver dam analogue (BDAs) as a stream restoration technique. Although BDAs are intended to reduce erosion and stream incision, few studies directly document the impact of BDAs on stream channel geomorphology. This study, therefore, assesses how a complex of five BDAs along a 150 m long stream reach in Red Canyon Ranch near Lander, WY impacts stream bank erosion and deposition and channel evolution over a 1‐year period post‐installation. Relative to control locations not impacted by BDAs, the BDA reach showed greater spatial heterogeneity in erosion and deposition patterns than control locations, as well as less overall erosion. However, each BDA had unique effects on channel morphology. Large amounts of deposition were found at the most upstream BDA remaining after the first year at both inner and outer meander locations. High flow events created breaches that likely produced significant stream bank erosion observed immediately downstream of the BDA complex. From a design standpoint, the only BDAs that remained after a year were those built around fence posts inserted into the stream bed with a percussion fence post driver. Overall, our short‐term data indicate that BDAs can be successfully used as a stream restoration practice to reduce stream bank erosion and increase channel geomorphological heterogeneity.
Construction of Nitrate Reductase Biosensor using Lab -on -Paper Technology and its Application in Nitrate level Management

Amperometric screen printed nitrate reductase biosensor has been developed to detect nitrate ions in aqueous environmental samples. The biosensor was designed by immobilizing the enzyme using glutaraldehyde with coupling agents Azure A and H2O2 as mediators on screen printed carbon electrodes. The biosensor developed was able to detect nitrate ions in different environmental samples up to 20ppm which is within the limit as suggested by European Union standards, representing cheap, rapid and applicable tool for environmental nitrate analysis.
MiR-133a-3p Functions as a Tumor Suppressor in Colorectal Cancer by Targeting PFKFB3

Background: Recent studies reveal that PFKFB3 plays an important role in tumorigenesis and tumor progression. Our study aims to identify an novel microRNA which can suppress the expression of PFKFB3 and to provide a potential target for tumor therapy.Methods: Bioinformatics methods were implemented to explore the expression and clinical significance of PFKFB3 and miR-133a-3p in colorectal cancer (CRC). qRT-PCR was performed to detect PFKFB3, miR-133a-3p, KI67 and MMP9 mRNA expression, while western bot was carried out for the detection of protein expression of PFKFB3, miR-133a-3p, KI67 and MMP9. Bioinformatics analysis was used to predict the binding sites of miR-133a-3p on PFKFB3 3’UTR, while dual-luciferase assay was conducted to validate their binding relationship. CCK-8 assay, KI67 detection, Transwell assay and MMP9 detection were employed to measure CRC cell proliferative and invasive abilities. Results: PFKFB3 is up-regulated in CRC and significantly associated with poor prognosis. Overexpressed PFKFB3 promotes CRC cell proliferation and invasion. miR-133a-3p is down-regulated and has diagnostic value in CRC. Dual-luciferase assay confirmed that there was a binding relationship between miR-133a-3p and PFKFB3.Overexpressed miR-133a-3p remarkably reduced PFKFB3 expression in CRC cells, weakened the promoting effect of PFKFB3 on cell proliferation and invasion.Conclusions: Our study suggests that miR-133a-3p functions as a novel tumor suppressor in colorectal cancer by targeting PFKFB3.
