Utilising Tree-Based Ensemble Learning for Speaker Segmentation

AbstractIn audio and speech processing, accurate detection of the changing points between multiple speakers in speech segments is an important stage for several applications such as speaker identification and tracking. Bayesian Information Criteria (BIC)-based approaches are the most traditionally used ones as they proved to be very effective for such task. The main criticism levelled against BIC-based approaches is the use of a penalty parameter in the BIC function. The use of this parameters consequently means that a fine tuning is required for each variation of the acoustic conditions. When tuned for a certain condition, the model becomes biased to the data used for training limiting the model’s generalisation ability.In this paper, we propose a BIC-based tuning-free approach for speaker segmentation through the use of ensemble-based learning. A forest of segmentation trees is constructed in which each tree is trained using a sampled version of the speech segment. During the tree construction process, a set of randomly selected points in the input sequence is examined as potential segmentation points. The point that yields the highest ΔBIC is chosen and the same process is repeated for the resultant left and right segments. The tree is constructed where each node corresponds to the highest ΔBIC with the associated point index. After building the forest and using all trees, the accumulated ΔBIC for each point is calculated and the positions of the local maximums are considered as speaker changing points. The proposed approach is tested on artificially created conversations from the TIMIT database. The approach proposed show very accurate results comparable to those achieved by the-state-of-the-art methods with a 9% (absolute) higher F 1 compared with the standard ΔBIC with optimally tuned penalty parameter.KeywordsRandom ForestBayesian Information CriterionGaussian Mixture ModelPenalty FactorBroadcast NewsThese keywords were added by machine and not by the authors.

Analysis of the indoor horse riding exercise equipment on the young people

The purpose of this study was to investigate the effect of indoor horse riding exercise equipment on the young people in their twenties. We classified the effects into flexibility, muscle strengthening, and muscular reaction. Subjects performed horse riding exercise using SRider (Neipplus Co. & Chonbuk National Univ, Korea) that we developed. Twenty male and twenty female subjects were included and they had no experience with horse riding as an exercise and no medical history of falling. Exercise was performed for 45 min a day and 3 days a week during 8 weeks in a constant temperature and humidity environment. Once a week, we conducted the bodyeffect measurements. We measured forward trunk flexion and backward trunk extension to verify the improvement of flexibility. We also measured lumbar joint torque using the BIODEX System3 to verify the improvement of muscle strength and reaction. Our results of flexibility showed that values of forward trunk flexion and backward trunk extension after the exercise were higher than those before the exercise. It also presented that the stimulated three-dimensional movement of the horse riding exercise activated joints and muscles not usually used. Besides, the continuous movement of horse riding can reduce muscle tonus and relax stiff muscles. The muscle strengthening and muscular reaction results showed that peak lumbar joint torque after the exercise was higher than that before the exercise. We found that the horse riding exercise using indoor equipment improved flexibility, muscle strength, and muscular reaction. Moreover, we hope that this work will help us understand the exercise characteristic of this equipment.
DESIGNING AND TESTING BLUEBERRY HYDROPONIC PLANTS BASED ON INTERNET OF THINGS (IoT)

Hydroponics is a method of farming or plants cultivation without using soil, but the technology of cultivation using water, nutrients, and oxygen. Using hydroponics system has advantages, such as the quantity and quality of production is better and cleaner, fertilizer and water usage is more efficient, pest and disease are easier to control. However, this system also has disadvantage such as hydroponics require precision, patience, and routine monitoring. Changes in pH, electrical conductivity in nutrients, water temperature, air temperature and light intensity influence the plants growth. It affects the quality of vegetable crops. Therefore, a monitoring becomes necessary by giving notice if there are changes in accordance with the grow crops requirements. The monitoring system uses pH sensor, Electro Conductivity sensor, water temperature sensor, air temperature, Light Sensor, Open Garden Shield, Open Garden Hydroponic, and Arduino Uno as a main board or a microcontroller. The results of tests conducted over several weeks on Blueberry fruit plants showed that a superfood fruit is somewhat sensitive to temperature and pH should not exceed pH 4 - 5 (acid). It only uses high sulfuric fertilizer. It cannot use organic fertilizer or NPK because it can neutralize the pH of the growing media. Therefore, it must be accompanied by a good and a consistent prairting system. The results of this implementation must be able to understand several factors of healing the fruit before conducting blueberry cultivation.

Adapter les territoires au risque d’inondation en France et en Espagne : vers de nouvelles pratiques d’aménagement des zones inondables ?

L’injonction actuelle à l’adaptation des territoires au changement climatique et à ses effets ne contribue-t-elle pas à l’émergence de nouvelles formes d’aménagement des zones exposées au risque d’inondation par débordement de cours d’eau ou submersion marine, via le développement de nouvelles pratiques opérationnelles visant à aménager avec l’inondabilité et l’eau ? Cette question est examinée grâce à une analyse comparée des politiques d’aménagement des zones inondables aujourd’hui mises en œuvre en France et en Espagne. En France, de nouvelles formes d’action publique voient le jour (au moins ponctuellement) afin de favoriser la résilience des territoires à l’inondation et leur adaptation aux conséquences du changement climatique. Les opérations d’urbanisme résilient et les acquisitions/démolitions de biens en zone à risque constituent deux manifestations de l’appropriation progressive de cette nouvelle logique par les acteurs de l’aménagement des territoires locaux. À l’inverse en Espagne, les initiatives s’inscrivant dans la logique du « faire avec » le risque d’inondation apparaissent bien plus embryonnaires. Toutefois, cette nouvelle perspective et les formes d’aménagement qui lui sont associées commencent à être mises en débat suite à de récents aléas naturels qui ne manquent pas de questionner les modes d’aménagement qui ont été privilégiés jusqu’à présent, en même temps qu’apparaissent des actions qui, promues par les collectivités territoriales, s’engagent pour un aménagement urbain plus résilient face au risque d’inondation.

New generation of polymeric films, ldpe-graphene based, for industrial applications

Barrier coatings and films are essential in many industries – like food/medical packaging, building or textiles – as a protection from moisture and bacteria, corrosion, heat, physical damage... However, the materials currently in use often offer a limited performance (e.g. plastics are not completely impenetrable), present a risk for human health and the environment (many metals and solvent-based coatings widely used as protective barriers are increasingly regulated for their toxicity) and/or show a growing trend of supply scarcity and price rise (unstable remote metal ores). A new generation of effective coating materials, eco-friendly and economically viable, is therefore urgently needed to improve the protection and safety of consumer and industrial goods. 
Taking up this challenge, we present GRAPHCOAT, a ground-breaking multifunctional barrier film made of Low-Density Polyethylene (LDPE) enhanced with high-quality and non-toxic graphene nanoplatelets and manufactured with our proprietary extrusion coating technology. Through its unique compound formulation and exploiting the unparalleled features of graphene, GRAPHCOAT offers outstanding barrier properties, excellent mechanical strength, heat dissipation and UV absorption properties, among others. It allows a longer life for consumer goods, enhanced food and medical safety, and require less raw material compared to current barrier technologies. 
Roncoroni is an Italian family-owned company with more than 50 years of experience in the lamination and coating field, and a consolidated customer base. Our new product has already raised the attention of many of our clients in the fields of industrial packaging, building insulation and protective clothing. Thanks to GRAPHCOAT, they will benefit from a last-generation, high-performance and sustainable range of products in their offering, that will lead them to long-term profitability. We, in turn, expect to reach +€13.7M revenues and hire 16 new people by 2025.
Now you see it: Genome methylation makes a comeback inDrosophila

Drosophila melanogaster is often considered to lack genomic 5-methylcytosine (m(5) C), an opinion reinforced by two whole genome bisulfite-sequencing studies that failed to find m(5) C. New evidence, however, indicates that genomic methylation is indeed present in the fly, albeit in small quantities and in unusual patterns. At embryonic stage 5, m(5) C occurs in short strand-specific regions that cover ∼1% of the genome, at tissue levels suggesting a distribution restricted to a subset of nuclei. Its function is not obvious, but methylation in subsets of nuclei would obscure functional associations since transcript levels and epigenetic modifications are assayed in whole embryos. Surprisingly, Mt2, the fly's only candidate DNA methyltransferase, is not necessary for the observed methylation. Full evaluation of the functions of genome methylation in Drosophila must await discovery and experimental inactivation of the DNA methyltransferase, as well as a better understanding of the pattern and developmental regulation of genomic m(5) C.
High throughput mass spectrometry of single proteins in liquid environment

Although mass spectrometry has brought about major advancements in proteomics in the last decade, protein mass spectrometers still have important limitations. One fundamental limitation is that they require sample ionization, desorption into the gas phase and fragmentation, clearly leading to protein denaturation. Since relevant protein complexes are unstable or transient, their characterization in its native state and physiological environment remains an unexplored route towards the full understanding of protein function and protein interactions. This problem has only been targeted to date through theoretical approaches or low throughput experimental techniques, such as atomic force spectroscopy, optical tweezers or FRET. A high throughput characterization technology capable of addressing single proteins in its native state would have a large impact in proteomics. The goal of LIQUIDMASS is to develop a high throughput spectrometric technique addressing single proteins from complex samples while in physiological conditions. LIQUIDMASS also proposes a new concept for protein spectrometry, by characterizing not only the mass, but also the hydrodynamic radius, geometry and stiffness of single proteins. This multiparameter approach will serve to open up new routes to understand protein structure-function relations by providing insight into the fast conformational changes that occur in liquids. In order to attain these goals, I propose to integrate nanomechanical resonators, nano-optics and nanofluidics. The disruptive approach proposed will bring about new knowledge about protein interactions and protein conformation that is elusive today. The enabling technologies aimed at the LIQUIDMASS will increase our understanding of protein misfolding related diseases, such as Alzheimer’s or diabetes, as well as bring closer a full understanding of the human interactome, contributing to the advancement of the proteomics field.
Short-term rentals in small cities in Oregon: Impacts and regulations

Governments across the country struggle to manage the impacts of short-term rentals (STRs), like Airbnbs, and the sharing economy more generally. Existing research is sparse and tends to focus on large cities or metropolitan areas. Focusing on 237 small cities in Oregon, this study relies on descriptive data from Airbnb, AirDNA, Oregon Department of Revenue, and the U.S. Census to examine the prevalence and characteristics of Airbnbs, revenue potential from lodging taxes, and the impact on long-term housing supply. This study also summarizes the findings from a statewide survey of city managers and planners on regulation and perceptions. We find that the prevalence of Airbnbs varies drastically across cities and is highest in tourist areas. Airbnbs are present on over five percent of the housing stock in 16 cities. While hosts generated $82 million in revenue, only 11 cities and four counties charge lodging taxes. In total, 38% of Airbnbs are whole homes that are rented more than 30 days in a year, signaling potential impacts on long-term rental supply. Finally, while cities perceive Airbnb to be an issue, only 35% of survey respondents are currently regulating Airbnbs. We find that cities need to understand prevalence and characteristics of STRs and respond with appropriate regulatory controls. Airbnb provides lodging and tourism where hotels have not been available in some cities, but in other cities, Airbnbs place pressure on tight housing markets and draw complaints from residents.
Capillary Imbibition of Gadolinium Halides into WS2 Nanotubes: a Molecular Dynamics View

The structure of the molten salts GdX3, where X denotes Cl, Br, or I, and the kinetics of their penetration into WS2 nanotubes were investigated using molecular dynamics simulations. The GdCl3 and GdBr3 melts are found to comprise an amorphous framework structure with substantial intermediate-range ordering, as manifested by pair distribution, and angle-resolved pair-pair distribution functions associated with cationic correlations. In contrast, the GdI3 melt is a liquid with short-range cationic ordering. These structural peculiarities cause dramatically different mobility of Gd cations among pure GdX3 melts and explain the relative difference in the capillary activity of WS2 nanotubes regarding the melts, as observed in preliminary experiments. Extended MD simulations of GdCl3 dissolved in molten KCl predict the total degradation of the GdCl3 framework structure below 40 mol %, although no essential uptake of Gd cations by the WS2 nanotube is observed, due to more progressive diffusion of K cations. Our theory suggests that, among the considered halides, only the GdI3 compound is suitable for Gd encapsulation into WS2 nanotubes employing the capillary technique.
Exploring the antecedents and consequences of mentoring relationship effectiveness in the healthcare environment

Abstract The study focused on mentoring relationship effectiveness (RE) from the perspective of protégé in the healthcare environment. The purpose tried to examine the effects of interpersonal attraction, self-efficacy and transformational leadership (TL) on RE respectively, to test mentoring function as a mediator, and to verify the effect of RE on protégé work outcomes. Self-administered questionnaires were employed and 306 questionnaires from hospital nurses were collected in total. Structural equation model was used to test the research model. The results indicated that interpersonal attraction and TL do have positive effects on RE while self-efficacy was not; RE also showed a significant effect on job satisfaction and organizational commitment, which verified that the formal mentoring among nurses was good for improving relationship quality and relationship learning between mentors and protégés. Accordingly, to strengthen the antecedent variables would be helpful for mentoring RE, and also the protégé's work outcomes.

Design of GaN HEMT based Doherty amplifiers

In this paper the design of high efficiency unsymmetrical Doherty power amplifiers (PAs) will be presented. The Doherty PAs were designed to achieve high average efficiency for digitally modulated signals with high peak to average power ratio (PAR) used in third (3G) and fourth (4G) generation systems. The Doherty amplifiers have been designed using two unequal sized GaN devices for the main Class-AB and peaking Class-C amplifiers. In the first narrow band design, a 50 W Doherty amplifier has been implemented at 2.5 GHz. A drain efficiency of 54% (48% power added efficiency (PAE)) has been measured at its maximum output power of 47 dBm. The efficiency remains constant up to the 6 dB output power back-off. Moreover, the Doherty PA has been linearized to achieve an Adjacent Channel Leakage Ratio (ACLR) of -46 dBc at 10 MHz offset for a 10 MHz (UMTS-LTE) signal with a PAR of 8.5 dB, and an average output power of 40 dBm. 44% PAE was measured for this signal constellation. In a second design, the status of a wideband unsymmetrical Doherty PA with 31% fractional bandwidth will be reported.
Monosaccharide Isomer Interconversions Become Significant at High Temperatures

Quantum-chemical calculations show how low barriers to anomerization and shifting equilibria cause a significant presence of different monosaccharide isomers in high-temperature processes such as pyrolysis. The transition between isomeric forms of monosaccharides is long-studied, but examination has typically been limited to the solution phase and to pyranose isomers. Processes and rates of anomerization by reversible, gas-phase ring-opening and -closing reactions were predicted for the monosaccharides d-glucose, d-mannose, d-galactose, d-xylose, l-arabinose, and d-glucuronic acid. Structures and thermochemistry were computed for stable species and pericyclic transition states using CBS-QB3, and high-pressure-limit Arrhenius reaction parameters were predicted and fitted from 300 to 1000 K. Activation energies for the ring-opening reactions were 162-217 kJ/mol for four-center pericyclic separation of the lactol group but were reduced by catalytic participation of a hydroxyl group within the monosaccharide or an external R-OH group represented by an explicit water molecule, reaching activation energies as low as 97 and 67 kJ/mol, respectively. Equilibrium constants implied increasing fractions of furanose and linear aldehyde anomers with increasing temperature.
Cranial aspergilloma masquerading as meningioma

Cranial aspergillosis may present as meningitis, cerebral abscess, cerebral infarcts/haemorrhages or extra-axial mass. Extra-axial cranial aspergilloma may mimic meningioma owing to mass-like characteristics and intense contrast enhancement on MRI there by delaying the diagnosis and further worsening the already bad prognosis in these patients. We present a 45-year-old gentleman who presented with signs of raised intracranial hypertension, secondary optic atrophy and a contrast-enhancing mass arising from the planum sphenoidale. Postoperatively, mass was diagnosed as aspergilloma on histopathology and culture. Despite antifungal treatment, patient could not be saved due to large artery infarcts in the immediate postoperative period. We discuss the clinical and MRI features that could help to have sufficient and early suspicion of fungal aetiology in these patients.
