9—THE PROPERTIES OF AIR-TEXTURED CONTINUOUS FILAMENT YARNS

A processing programme is outlined in which yarn pre-twist, applied air-pressure, and supply-yarn overfeed are systematically varied in the air-jet bulking process to investigate their effects on air-textured nylon 6.6 continuous-filament yarns. Optical magnification of the air-textured yarns enables the average loop sizes and frequencies to be measured. The experimental results are shown to be in general agreement with a suggested mechanism of the process, which argues that the initial filament twist in the parent yarn redistributes itself as snarled loops and that the overfed yarn contributes to the size of such loops; the deflexion of filaments by air-drag forces is also shown to make a contribution to a looping effect, which can be estimated theoretically. Increasing the yam overfeed increases both the loop size and the loop frequency. Increasing the yam pre-twist decreases the loop size and increases the loop frequency. Increasing the air-pressure also decreases the loop size and increases the loop f.
MDP Optimal Control under Temporal Logic Constraints-Technical Report -

In this paper, we develop a method to automatically generate a control policy for a dynamical system modeled as a Markov Decision Process (MDP). The control specification is given as a Linear Temporal Logic (LTL) formula over a set of propositions defined on the states of the MDP. We synthesize a control policy such that the MDP satisfies the given specification almost surely, if such a policy exists. In addition, we designate an “optimizing proposition” to be repeatedly satisfied, and we formulate a novel optimization criterion in terms of minimizing the expected cost in between satisfactions of this proposition. We propose a sufficient condition for a policy to be optimal, and develop a dynamic programming algorithm that synthesizes a policy that is optimal under some conditions, and sub-optimal otherwise. This problem is motivated by robotic applications requiring persistent tasks, such as environmental monitoring or data gathering, to be performed.
"Early" vs. "late" diagnosis of celiac disease in two ethnic groups living in the same geographic area.

Despite studies documenting existence of celiac disease worldwide, its prevalence in many parts of the world is underestimated and cases remain unrecognized. In Israel, celiac disease is relatively common among the Jewish population but considered to be rarer among the Arab population. We compared the manifestations of celiac disease in children of both ethnic groups and questioned whether differences in presentation relate to degree of awareness for celiac disease in each group. Age at presentation, time interval between onset of symptoms and diagnosis, prevalence of gastrointestinal symptoms, presence of signs of malabsorption and degree of growth retardation varied markedly between both groups. In populations in which there is a low index of suspicion for celiac disease, symptoms may be wrongly attributed to the post-gastroenteritis syndromes or protein-calorie malnutrition, thus resulting in a detrimental delay in diagnosis. Undiagnosed cases may in later childhood manifest predominantly as short stature.
Phylogenomic Study Indicates Widespread Lateral Gene Transfer in Entamoeba and Suggests a Past Intimate Relationship with Parabasalids

Lateral gene transfer (LGT) has impacted the evolutionary history of eukaryotes, though to a lesser extent than in bacteria and archaea. Detecting LGT and distinguishing it from single gene tree artifacts is difficult, particularly when considering very ancient events (i.e., over hundreds of millions of years). Here, we use two independent lines of evidence—a taxon-rich phylogenetic approach and an assessment of the patterns of gene presence/absence—to evaluate the extent of LGT in the parasitic amoebozoan genus Entamoeba. Previous work has suggested that a number of genes in the genome of Entamoeba spp. were acquired by LGT. Our approach, using an automated phylogenomic pipeline to build taxon-rich gene trees, suggests that LGT is more extensive than previously thought. Our analyses reveal that genes have frequently entered the Entamoeba genome via nonvertical events, including at least 116 genes acquired directly from bacteria or archaea, plus an additional 22 genes in which Entamoeba plus one other eukaryote are nested among bacteria and/or archaea. These genes may make good candidates for novel therapeutics, as drugs targeting these genes are less likely to impact the human host. Although we recognize the challenges of inferring intradomain transfers given systematic errors in gene trees, we find 109 genes supporting LGT from a eukaryote to Entamoeba spp. , and 178 genes unique to Entamoeba spp. and one other eukaryotic taxon (i.e., presence/absence data). Inspection of these intradomain LGTs provide evidence of a common sister relationship between genes of Entamoeba (Amoebozoa) and parabasalids (Excavata). We speculate that this indicates a past close relationship (e.g., symbiosis) between ancestors of these extant lineages.
Effect of Polymer Crystallinity on Morphology in Ceramic Injection Molding

Many ceramic injection molding vehicles include semicrystalline polymers which characteristically adopt a spherulitic growth morphology. Usually the spherulites are rendered invisible by the opacity of the ceramic powder but in this study they are clearly visible. Polyoxymethylene (POM), has been used as the vehicle. The growth of the spherulites is shown to be dependent on cooling rate and hence on position in the molding. Furthermore, migration of low molecular weight additives by syneresis is shown to occur and to influence the crack path in the as-molded state. An unusual composite fractograph is shown in which fracture faces made after molding, after binder removal, and after sintering are contiguous. Only after molding does the crack path follow the spherulite boundaries; behavior that is also widely reported for unfilled POM.
4.1: A 20‐inch OLED Display Driven by Super‐Amorphous‐Silicon Technology

A 20‐inch, largest OLED display in the world is demonstrated which is driven by “Super Amorphous Silicon” technology. It has been widely believed that the characteristics of amorphous silicon TFT is not sufficient to drive OLED display. This paper turns over the hypothesis to prove that amorphous silicon can be applied to the large active‐matrix driven displays. Novel approaches to enable amorphous silicon to drive bright and long life OLED display are shown to open a bright future to realize larger OLED televisions.
Thoughts on Multi-Disciplinary Inspired Research on Open Network and Information System

Current and future computing system acting as the fundamental infrastructure of our society should be multi-disciplinary research topics, and possess the economic-social characteristics which reflect the features of our society. Specifically, in this paper, we propose a unified framework to categorize and describe research problems in socially-inspired computing system from two distinctive viewpoints. That is, in macro-level, we propose architectural space including economic space, intelligent space and trust space to characterize the whole system; in micro-level, we demonstrate that it is suitable to adapt some interdisciplinary concepts and theories to better understand and properly address problems in communications network. Finally, we illustrate the interdependence between architectural space and interaction space, that is, the local interaction behaviors should shape and be shaped by architectural properties.
Impact of cone beam computed tomography on measurement of bone density in periapical lesions following endodontic treatment: A clinical study

Objective: Differences in bone density before and after regenerative endodontic treatment were examined in teeth with periapical lesions in Hounsfield Units (HUs) by using Cone Beam Computed Tomography (CBCT). Materials and Methods: 8 patients requiring regenerative endodontic treatment for periapical lesions underwent CBCT scan before and after treatment. Their bone densities were calculated in HUs. The study included 10 teeth with periapical lesions measuring 4-8 mm in diameter. HU measurements were taken from an area of 3.5 mm2 on the CBCT images where the bone density was lowest, before and after treatment. The initial and final measurements were compared statistically by using paired samples statistics at the 5% significance level. Results: There was a highly significant difference between the initial and final measurements (HU values) before and 1 year after endodontic treatment (P<0.0001). Conclusion: We conclude that CBCT is a valuable tool for detecting the bone growth in periapical lesions.
Plant growth-promoting endophytic bacteria versus pathogenic infections: an example of Bacillus amyloliquefaciens RWL-1 and Fusarium oxysporum f. sp. lycopersici in tomato

Fungal pathogenic attacks are one of the major threats to the growth and productivity of crop plants. Currently, instead of synthetic fungicides, the use of plant growth-promoting bacterial endophytes has been considered intriguingly eco-friendly in nature. Here, we aimed to investigate the in vitro and in vivo antagonistic approach by using seed-borne endophytic Bacillus amyloliquefaciens RWL-1 against pathogenic Fusarium oxysporum f. sp. lycopersici. The results revealed significant suppression of pathogenic fungal growth by Bacillus amyloliquefaciens in vitro. Further to this, we inoculated tomato plants with RWL-1 and F. oxysporum f. sp. lycopersici in the root zone. The results showed that the growth attributes and biomass were significantly enhanced by endophytic-inoculation during disease incidence as compared to F. oxysporum f. sp. lycopersici infected plants. Under pathogenic infection, the RWL-1-applied plants showed increased amino acid metabolism of cell wall related (e.g., aspartic acid, glutamic acid, serine (Ser), and proline (Pro)) as compared to diseased plants. In case of endogenous phytohormones, significantly lower amount of jasmonic acid (JA) and higher amount of salicylic acid (SA) contents was recorded in RWL-1-treated diseased plants. The phytohormones regulation in disease incidences might be correlated with the ability of RWL-1 to produce organic acids (e.g., succinic acid, acetic acid, propionic acid, and citric acid) during the inoculation and infection of tomato plants. The current findings suggest that RWL-1 inoculation promoted and rescued plant growth by modulating defense hormones and regulating amino acids. This suggests that bacterial endophytes could be used for possible control of F. oxysporum f. sp. lycopersici in an eco-friendly way.
Biomechanical Study on Distal Filling Effects in Cementless Total Hip Replacement

In cementless total hip replacement, initial stability of the femoral component is important in the long term fixation of the femoral stem. Initial stability is closely related to the relative displacement between the prosthesis and the cancellous bone of the proximal femur. After implantation of the prosthesis, the surrounding bone is partially shielded from load carrying and starts to resorb. Stress shielding causes the loss of the proximal bone. The stress distribution of femur must be assessed to predict stress shielding. The initial stability and the stress shielding were investigated for two loading conditions approximating a single leg stance and stair climbing. Two types of stems involving a distal filling and a distal short stem were studied by the finite element method to investigate the biomechanical distal filling effects. The distal short stem produced less stress shielding at the proximal bone than the distal filling stem, while both types of stems seemed to satisfy the initial stability requirement.
A Ring-Oscillator-Based Reliability Monitor for Isolated Measurement of NBTI and PBTI in High-k/Metal Gate Technology

Ring-oscillator-based test structures that can separately measure the negative bias temperature instability (NBTI) and positive bias temperature instability (PBTI) degradation effects in digital circuits are presented for high-k metal gate devices. The mathematical derivation also shows that the structure for frequency degradation measurement can directly be used for estimating the portion of the NBTI and PBTI in the conventional ring oscillator. The proposed test structures including frequency degradation sensing circuitry have been implemented in an experimental high-k/metal gate SoI process.
Reliability and Validity of the Chinese Version Appropriateness Evaluation Protocol

Objective To adapt the Appropriateness Evaluation Protocol (AEP) to the specific settings of health care in China and to validate the Chinese version AEP (C-AEP). Methods Forward and backward translations were carried out to the original criteria. Twenty experts participated in the consultancy to form a preliminary version of the C-AEP. To ensure applicability, tests of reliability and validity were performed on 350 admissions and 3,226 hospital days of acute myocardial infraction patients and total hip replacement patients in two tertiary hospitals by two C-AEP reviewers and two physician reviewers. Overall agreement, specific agreement, and Cohen’s Kappa were calculated to compare the concordance of decisions between pairs of reviewers to test inter-rater reliability and convergent validity. The use of “overrides” and opinions of experts were recorded as measurements of content validity. Face validity was tested through collecting perspectives of nonprofessionals. Sensitivity, specificity, and predictive values were also reported. Results There are 14 admission and 24 days of care criteria in the initial version of C-AEP. Kappa coefficients indicate substantial agreement between reviewers: with regard to inter-rater reliability, Kappa (κ) coefficients are 0.746 (95% confidence interval [CI] 0.644–0.834) and 0.743 (95% CI 0.698–0.767) of admission and hospital days, respectively; for convergent validity, the κ statistics are 0.678 (95% CI 0.567–0.778) and 0.691 (95% CI 0.644–0.717), respectively. Overrides account for less than 2% of all judgments. Content validity and face validity were confirmed by experts and nonprofessionals, respectively. According to the C-AEP reviewers, 18.3% of admissions and 28.5% of inpatient days were deemed inappropriate. Conclusions The C-AEP is a reliable and valid screening tool in China’s tertiary hospitals. The prevalence of inappropriateness is substantial in our research. To reduce inappropriate utilization, further investigation is needed to elucidate the reasons and risk factors for this inappropriateness.
Sparse representation with nearest subspaces for face recognition

This paper proposes a supervised sparse representation based classification method for face recognition. The proposed method consists of two phases. The first phase seeks k nearest subspaces for the test sample from the c classes, and converts the c -class classification problem into a k -class problem, where c is the number of classes and k is a parameter. We can do this because, as validated by the experiments, the test sample belongs to one of these k subspaces with a very high probability. The second phase represents the test sample using these k nearest subspaces. This phase enhances the sparability by increasing the contribution of right subspace and suppressing those of the others. Via the above two phases, the proposed method introduces an approach to gain the sparsity in representation. The experimental results show the feasibility of the proposed method in face recognition.
The Human IGF1R IRES likely operates through a Shine–Dalgarno‐like interaction with the G961 loop (E‐site) of the 18S rRNA and is kinetically modulated by a naturally polymorphic polyU loop

IGF1R is a proto‐oncogene with potent mitogenic and antiapoptotic activities, and its expression must be tightly regulated to maintain normal cellular and tissue homeostasis. We previously demonstrated that translation of the human IGF1R mRNA is controlled by an internal ribosome entry site (IRES), and delimited the core functional IRES to a 90‐nucleotide segment of the 5′‐untranslated region positioned immediately upstream of the initiation codon. Here we have analyzed the sequence elements that contribute to the function of the core IRES. The Stem2/Loop2 sequence of the IRES exhibits near‐perfect Watson–Crick complementarity to the G961 loop (helix 23b) of the 18S rRNA, which is positioned within the E‐site on the platform of the 40S ribosomal subunit. Mutations that disrupt this complementarity have a negative impact on regulatory protein binding and dramatically decrease IRES activity, suggesting that the IGF1R IRES may recruit the 40S ribosome by a eukaryotic equivalent of the Shine–Dalgarno (mRNA–rRNA base‐pairing) interaction. The homopolymeric Loop3 sequence of the IRES modulates accessibility and limits the rate of translation initiation mediated through the IRES. Two functionally distinct allelic forms of the Loop3 poly(U)‐tract are prevalent in the human population, and it is conceivable that germ‐line or somatic variations in this sequence could predispose individuals to development of malignancy, or provide a selectable growth advantage for tumor cells.

BIOCOMPATIBLE FLUORESCENT MICROSPHERES: SAFE PARTICLES FOR MATERIAL PENETRATION STUDIES

Biocompatible polymers with hydrolyzable chemical bonds are being used to produce safe, non-toxic fluorescent microspheres for material penetration studies. The selection of polymeric materials depends on both biocompatibility and processability, with tailored fluorescent properties depending on specific applications. Microspheres are composed of USFDA-approved biodegradable polymers and non-toxic fluorophores and are therefore suitable for tests where human exposure is possible. Micropheres are being produced which contain unique fluorophores to enable discrimination from background aerosol particles. Characteristics that affect dispersion and adhesion can be modified depending on use. Several different microsphere preparation methods are possible, including the use of a vibrating orifice aerosol generator (VOAG), a Sono-Tek atomizer, an emulsion technique, and inkjet printhead. The advantages and disadvantages of each method will be presented and discussed in greater detail along with fluorescent and charge properties of the aerosols. Applications for the fluorescent microspheres include challenges for biodefense system testing, calibrants for biofluorescence sensors, and particles for air dispersion model validation studies.
Medicinal Decision Support System for Cardiovascular Disease using Data Mining Techniques

Restorative science industry has tremendous measure of information, however shockingly the vast majority of this information is not mined to discover out shrouded data in information. Propelled information mining systems can be utilized to find shrouded design in information. Models created from these systems will be valuable for medicinal professionals to take successful choice. In this examination paper, one of the information mining arrangement system Decision Tree calculation C4. 5, ID3 and CART are dissected on cardiovascular illness dataset. Exhibitions of these calculations are thought about through affectability, specificity, exactness, blunder rate, True Positive Rate and False Positive Rate. In our studies 10-fold cross acceptance system was utilized to gauge the impartial evaluation of these expectation
Linear and nonlinear equivalent circuit modeling of CMUTs

Using piston radiator and plate capacitance theory capacitive micromachined ultrasound transducers (CMUT) membrane cells can be described by one-dimensional (1-D) model parameters. This paper describes in detail a new method, which derives a 1-D model for CMUT arrays from finite-element methods (FEM) simulations. A few static and harmonic FEM analyses of a single CMUT membrane cell are sufficient to derive the mechanical and electrical parameters of an equivalent piston as the moving part of the cell area. For an array of parallel-driven cells, the acoustic parameters are derived as a complex mechanical fluid impedance, depending on the membrane shape form. As a main advantage, the nonlinear behavior of the CMUT can be investigated much easier and faster compared to FEM simulations, e.g., for a design of the maximum applicable voltage depending on the input signal. The 1-D parameter model allows an easy description of the CMUT behavior in air and fluids and simplifies the investigation of wave propagation within the connecting fluid represented by FEM or transmission line matrix (TLM) models.
Framework for finite alternative theories to a quantum field theory

Using the path-integral formalism, we generalize the 't Hooft-Veltman method of unitary regulators to put forward a framework for finite, alternative quantum theories to a given quantum field theory. Feynman-like rules of such a finite, alternative quantum theory lead to alternative, perturbative Green functions. Which are acceptably regularized perturbative expansions of the original Green functions, causal, and imply no unphysical free particles. To demonstrate that the proposed framework is feasible, we take the quantum field theory of a single, self-interacting real scalar field and show how we can alter, covariantly and locally, its free-field Lagrangian to obtain finite, alternative perturbative Green functions.
Iris or Periocular? Exploring Sex Prediction from Near Infrared Ocular Images

Recent research has explored the possibility of automatically deducing the sex of an individual based on near infrared (NIR) images of the iris. Previous articles on this topic have extracted and used only the iris region, while most operational iris biometric systems typically acquire the extended ocular region for processing. Therefore, in this work, we investigate the sex-predictive accuracy associated with four different regions: (a) the extended ocular region; (b) the iris-excluded ocular region; (c) the iris-only region and (d) the normalized iris-only region. We employ the BSIF (Binarized Statistical Image Feature) texture operator to extract features from these regions, and train a Support Vector Machine (SVM) to classify the extracted feature set as Male or Female. Experiments on a dataset containing 3314 images suggest that the iris region only provides modest sex-specific cues compared to the surrounding periocular region. This research further underscores the importance of using the periocular region in iris recognition systems.
Synovial fluid-derived mesenchymal stem cells increase after intra-articular ligament injury in humans.

OBJECTIVE The existence of mesenchymal stem cells (MSCs) in SF was previously reported. However, the behaviour and properties of MSCs derived from SF have not been fully elucidated. METHODS Human SFs were obtained from 19 knee joints with anterior cruciate ligament injury around the time of reconstruction surgery, and from three healthy volunteers. SF was plated, cultured and examined for colony-forming number, in vitro differentiation, surface epitopes and gene profiles. Also, rabbit synovium-MSCs were injected into the knee joint in a rabbit partial anterior cruciate ligament defect model, and the injected cells were traced. RESULTS SF-MSCs from IA ligament injury patients were 100 times more in number than those from healthy volunteers. Total colony number was positively correlated with post-injury period. No significant differences were observed among the cells derived from SF around the time of the surgery in relation to surface epitopes and differentiation potentials. Cluster analysis of gene profiles demonstrated that SF-MSCs were more similar to synovium MSCs than bone marrow MSCs. In rabbit experiments, the MSCs injected into the knee in which IA ligament was partially defective were observed more on the defected area than on the intact area of the ligament at 24 h. CONCLUSION We demonstrated that SF-MSCs, similar to synovium MSCs, increased in number after IA ligament injury and surgery without marked alteration of the properties.
