Opis:
Electroencephalograph (EEG) data provide insight into the interconnections and relationships between various cognitive states and their corresponding brain dynamics, by demonstrating dynamic connections between brain regions at different frequency bands. While sensory input tends to stimulate neural activity in different frequency bands, peaceful states of being and self-induced meditation tend to produce activity in the mid-range (Alpha). These studies were conducted with the aim of: (a) testing different equipment in order to assess two (2) different EEG technologies together with their benefits and limitations and (b) having an initial impression of different brain states associated with different experimental modalities and tasks, by analyzing the spatial and temporal power spectrum and applying our movie making methodology to engage in qualitative exploration via the art of encephalography. This study complements our previous study of measuring multichannel EEG brain dynamics using MINDO48 equipment associated with three experimental modalities measured both in the laboratory and the natural environment. Together with Hilbert analysis, we conjecture, the results will provide us with the tools to engage in more complex brain dynamics and mental states, such as Meditation, Mathematical Audio Lectures, Music Induced Meditation, and Mental Arithmetic Exercises. This paper focuses on open eye and closed eye conditions, as well as meditation states in laboratory conditions. We assess similarities and differences between experimental modalities and their associated brain states as well as differences between the different tools for analysis and equipment.

Opis:
A novel data knowledge representation with the combination of structure learning ability of preprocessed collaborative fuzzy clustering and fuzzy expert knowledge of TakagiSugeno-Kang type model is presented in this paper. The proposed method divides a huge dataset into two or more subsets of dataset. The subsets of dataset interact with each other through a collaborative mechanism in order to find some similar properties within eachother. The proposed method is useful in dealing with big data issues since it divides a huge dataset into subsets of dataset and finds common features among the subsets. The salient feature of the proposed method is that it uses a small subset of dataset and some common features instead of using the entire dataset and all the features. Before interactions among subsets of the dataset, the proposed method applies a mapping technique for granules of data and centroid of clusters. The proposed method uses information of only half or less/more than the half of the data patterns for the training process, and it provides an accurate and robust model, whereas the other existing methods use the entire information of the data patterns. Simulation results show the proposed method performs better than existing methods on some benchmark problems.

Opis:
We report muon spin rotation studies of the magnetic field distribution n(B) in the vortex state of the high-temperature superconductor Bi$\text{}_{2}$Sr$\text{}_{2}$CaCu$\text{}_{2}$O$\text{}_{8+δ}$. From our data on three sets of overdoped, nearly optimized and underdoped single crystals we obtain evidence for a two-stage melting process of the vortex matter under equilibrium conditions. In the irreversible regime well below the irreversibility line we observe a transition in the vortex state which we associate with an intra-planar melting transition. The resulting flux-line liquid phase persists over a sizeable temperature interval before the inter-planar decoupling of the individual vortex lines takes place in a second step at the irreversibility line, resulting in a pancake liquid phase.

Opis:
The development of low-cost organic/inorganic puncture-resisting composites is suggested to improve their puncture resistance and thermal insulation properties. In this paper, recycled high modulus Kevlar fiber and glass fabric were used together with polyester/lowmelting polyester nonwovens. The result shows that the static puncture resistance improves proportionally with Kevlar fibers; but the dynamic puncture resistance remains the same at first and then rises up to 20 wt % for Kevlar fibers. The increasing low-melting polyester fibers on the surface result in an upward and then downward trend for both static and dynamic puncture resistances. The additional polyester/low-melting polyester nonwovens are beneficial for the improvement of puncture resistances. Moreover the thermal conductivity of all the composites is in range of 0.015-0.025 W/m·K. According to the results, Kevlar fibers are also shown to be advisable reinforcement to achieve better tensile and bursting strengths.
Badano możliwości zwiększenia odporności na przebicie oraz odporności termicznej tanich organiczno-nieorganicznych kompozytów. W badaniach stosowano wysoko modułowe włókna Kevlar z recyklingu oraz tkaninę z włókien szklanych łącznie z włókninami wykonanymi z niskotopliwego poliestru. Stwierdzono, że statyczna wytrzymałość na przebicie zwiększa się proporcjonalnie z ilością włókien Kevlar, ale dynamiczna wytrzymałość na przebicie pozostaje początkowo taka sama, a następnie wzrasta do zawartości włókien Kevlar 20%. Zastosowanie niskotopliwych włókien poliestrowych powoduje tendencje wzrastające, a następnie malejące dla wytrzymałości statycznej i dynamicznej. Stwierdzono, że dodatek włókien Kevlar jest korzystny dla wytwarzanych kompozytów.

Opis:
This study focused on the effects of microstructures on the low-temperature impact toughness of directly water-quenched offshore steel. Martensite dominated the microstructure directly below the quenched surface. In contrast, mainly lower bainite, martensite, and low amount of ferrite were observed in the central region of the quenched specimen. The ductile to brittle transition temperature of tempered martensite was significantly lower than that of a bainite-dominated microstructure. It is found that low-angle boundaries within the bainite packets greatly impair the low-temperature impact toughness of the steel. The absence of high-angle boundaries in the lower bainite packets significantly deteriorates the low-temperature impact energy of offshore steel.

Opis:
The vegetation blanket is the most common choice for soil and water preservation. This is a feasible method that protects the land and environment according to basic agriculture and engineering theories. This study manufactured eco-friendly nonwoven vegetation blankets by using cotton fibers, far-infrared fibers, PLA fibers, and low melting-point fibers at a 1:1:7:1 ratio. This ratio yielded from the pilot study provides the resulting vegetation blankets’ optimum air permeability and water absorption. This study further finds that a needle-punching density of 30 needles/cm2 allows fibers to lie in a loose structure, and therefore yielding the optimum air permeability and water absorption. In plant growth evaluation, for nonwoven vegetation blankets that contain 50 wt% far-infrared fibers, the plant growth length is 1.3 times greater than that of blankets with 10 wt% far-infrared fibers. This result proves that far-infrared fibers have usually been applied to plant growth.
Mata wegetacyjna jest najczęściej wybieraną formą ochrony zbocza dla zapewnienia odpowiedniego nawodnienia w celu wzrostu roślin. Jest to metoda, która chroni ziemię i środowisko naturalne zgodnie z zaleceniami nauk rolniczych. W artykule opisano otrzymywanie ekologicznej włókninowej maty wegetacyjnej z włókien bawełnianych, włókien ultraczułych na podczerwień, włókien polilaktydowych oraz włókien o niskiej temperaturze topnienia w stosunku 1:1:1:7. Wskaźnik ten, uzyskany z badania pilotażowego, zapewnia optymalną przepuszczalność powietrza i wchłanianie wody. Stwierdzono ponadto, że gęstość igłowania 30 igieł/cm2 umożliwia luźne ułożenie włókien, a więc pozwala na uzyskanie optymalnej przepuszczalności powietrza i absorpcji wody. W ocenie wzrostu roślin, na włókninowych matach wegetacyjnych, które zawierają 50% wagowych włókien ultraczułych na podczerwień, długość wzrostu roślin jest 1,3 razy większa, niż mat z 10% wagowymi włókien ultraczułych na podczerwień. Użycie włókien ultraczułych na podczerwień jest korzystne dla produkcji eko-włóknin zabezpieczających zbocza.

Opis:
A new psittacosaurid is based on a nearly complete articulated skeleton from northeastern China that differs principally in skull size as compared to the most common and widespread species, Psittacosaurus mongoliensis. The skull of Psittacosaurus majorsp. nov., is 25% larger despite very similar postcranial skeletal dimensions. Such selective skull enlargement is very unusual. Skull size in ceratopsians, in general, scales with positive allometry relative to body mass: species of greater mass have proportionately larger skulls. This pattern stands in marked contrast to that for other vertebrate herbivores, in which larger−bodied species either have proportionately similar or smaller skulls relative to body mass. Larger−bodied ceratopsians evolved skulls that are 50% or more of trunk length—as measured without their expansive cranial frill. Although contemporaneous duck−billed dinosaurs also exhibit some positive allometry in the skull, skull length remains approximately 35% of trunk length. The evolution of extraordinary absolute and relative skull size among ceratopsians appears to have been driven by sexual selection and involved the tandem evolution of reduced head mobility and an obligate quadrupedal posture.

Opis:
This study comparatively presents the static puncture property of different structures of intra-/inter-laminar reinforced hybrid composites via needle punching and thermal bonding techniques. The tensile and bursting properties of two composites with inter-laminar reinforcement by needle-punching and inter-and-intra- laminar reinforcement by both needle punching and using Kevlar fibres were also evaluated comparatively. The significance of process parameters including the low-melting PET fibre content, take-up speed of the punching machine, the plied orientation between the nonwoven and fabric and thermal bonding on the static puncture resistance was firstly investigated to seek out the significant parameters. The effects of significant processing parameters on static puncture and mechanical properties were explored afterwards. The research result shows that the plied orientation, low-melting PET content and thermal bonding affect the static puncture resistance most significantly. The maximum tensile strength and bursting strength occurred when hybrid composites after thermal bonding were composed of parallel-plied nonwovens and 90°-orientated glass fabric, as well as 70 wt% low-melting PET fibres. Recycled Kevlar fibre reinforcement dissipates additional static puncture resistance, and makes the static puncture resistance higher, as well as the tensile and bursting strengths for resultant hybrid fibre composites. Employing recycled Kevlar fibres is economical for the fabrication of hybrid composites. Diversified economical hybrid composites will be applied as a wall interlayer or garment interlining in the future.

Opis:
The structure of thin water films during the rupture process was investigated by a new approach, which combines molecular dynamics simulation (MDS) with image processing analysis. The analysis procedure was developed to convert MDS trajectories to readable 3D images. The water films were studied at different thicknesses by MDS to determine the critical thickness at which the film ruptures. The potential energy of each specific film thickness during the simulation time was analyzed, and the results showed that the potential energy of stable films remained unchanged while the potential energy kept decreasing for films which ruptured during the simulation time. By applying the new procedure, the molecular porosity, which is defined as the void fraction between the volume of molecular pores in the water film and the total volume of the water film, was calculated. The results of molecular porosity for different film thicknesses during the simulation time suggested a critical molecular porosity as 49%. In other words, stable films have a molecular porosity of less than 49%. If a water film has a molecular porosity greater than 49%, rupture occurs during the simulation.

Opis:
A unique dinosaur assemblage from the Cretaceous beds of western Inner Mongolia preserves geologic and paleontologic data that clearly delineate both the timing and mechanism of death. Over twenty individuals of the ornithomimid Sinornithomimus dongi perished while trapped in the mud of a drying lake or pond, the proximity and alignment of the mired skeletons indicating a catastrophic mass mortality of a social group. Histologic examination reveals the group to consist entirely of immature individuals between one and seven years of age, with no hatchlings or mature individuals. The Sinornithomimus locality supports the interpretation of other, more taphonomically ambiguous assemblages of immature dinosaurs as reflective of juvenile sociality. Adults of various nonavian dinosaurs are known to have engaged in prolonged nesting and post hatching parental care, a life history strategy that implies juveniles spent considerable time away from reproductively active adults. Herding of juveniles, here documented in a Cretaceous ornithomimid, may have been a common life history strategy among nonavian dinosaurs reflecting their oviparity, extensive parental care, and multi−year maturation.

Opis:
This study reports the findings of an argon (Ar) plasma treatment added to the traditional pad-dry-cure process between dry and cure treatments. This new process is called the "paddry-plasma-cure process". The crosslinking agent was a mixture of dimethyloldihydroxyethyleneurea (DMDHEU) and maleic acid (MA). Results show that Ar plasma treatment can increase the bonded crosslinking agent (i.e., the nitrogen content). The dry crease recovery angle (DCRA), wet crease recovery angle (WCRA), and tensile strength retention (TSR) of the pad-dry-plasma-cure finished fabrics were higher than those of traditional pad-dry-cure finished fabrics at a given nitrogen content. Additionally it was found that the number of crosslinks per anhydroglucose unit (CL/AGU) and the length of crosslinks of pad-dry-plasma-cure-finished fabrics were higher than that of traditional pad-dry-cure finished fabrics at the same resin concentration in the pad bath. DCRA, WCRA and TSR values of pad-dry-plasma-cure-finished fabrics were higher than those of pad-dry-curefinished fabrics at the same CL/AGU value. However, activation energies for the pad-dryplasma-cure process were higher than those for the pad-dry-cure process. The anti-bacterial ability and odour absorption of the pad-dry-plasma-cure and pad-dry-plasma-cure finished fabrics were higher than those for the pad-dry-cure finished fabrics. The surface distribution of crosslinking agents for the pad-dry-plasma-cure process was higher than that of the pad-dry-cure process. Thus the pad-dry-plasma-cure process is excellent for improving the physical properties, bacterial inhibition, and odour absorption of finished cotton fabrics and for decreasing their formaldehyde release.
Artykułu odnosi się do problematyki możliwości i celowości wprowadzenia modyfikacji plazmowej w warunkach niskociśnieniowych i w środowisku argonu do konwencjonalnego procesu wykończenia przeciw mnącego z zastosowaniem reaktywnych żywic termoutwardzalnych. Badano kąt odprężenia na sucho i na mokro, i stwierdzono polepszenie właściwości odporności na zagniecenia w wyniku dodatkowego zastosowania plazmy. Badano również właściwości antybakteryjne i pochłanianie zapachów, które okazały się korzystniejsze dla dodatkowej obróbki plazmowej. W wyniku zmodyfikowanej obróbki uzyskano mniejsze wydzielanie formaldehydu z gotowej tkaniny.

Information regarding the correct pedigree of and relationship between animals is useful for managing dairy breeding, reducing inbreeding, estimating breeding value, and establishing correct breeding programs. Additionally, the successful implementation of progeny testing is crucial for improving the genetics of dairy cattle, which depends on the availability of correct pedigree information. Incorrect pedigree information leads to bias in bull evaluation. In this study, Neogen GeneSeek Genomic Profiler (GGP) 50K SNP chips were used to identify and verify the sire of Taiwanese Holstein dairy cattle and analyze the reasons that lead to incorrect sire records. Samples were collected from 2,059 cows of 36 dairy farms, and the pedigree information was provided by breeders. The results of sire verification can be divided into three categories: submitted unconfirmed sire, submitted confirmed sire, and incorrectly submitted verified sire. Data on the sires of 1,323 (64.25%) and 572 (27.78%) dairy cows were verified and discovered, respectively. Sires of 1,895 (92.03%) dairy cattle were identified, which showed that the paternal pedigree of dairy cattle could be discovered and verified through genetic testing. An error-like analysis revealed that the data of 37 sires were incorrectly recorded because the bull’s NAAB code number was incorrectly entered into the insemination records: for 19 sires, the wrong bull was recorded because the frozen semen of a bull placed in the wrong storage tank was used, 6 had no sire records, and for 12 sires, the NAAB code of the correct bull was recorded but with a wrong stud code, marketing code, or unique number for the stud or breed. To reduce recorded sire error rates by at least 27.78%, automated identification of the mated bull must be adopted to reduce human error and improve dairy breeding management on dairy farms.
