Wireless communication is common use on devices to send or exchange information such computer peripheral, mobile device, home appliances, etc. Every device embedded with wireless module and contribute electromagnetic, thus high possibility of occurring interference. One of method how to control interference is by controlling signal to transmit as well as power, thus in this research designed reconfigurable MIMO antenna to control antenna radiation pattern to reduce interference issue in wireless communication. The antenna designed in 2.4 GHz band because most and common use of devices peripheral using unlicensed band as well as for Wireless Fidelity (Wi-Fi). The designed antenna is 4×4 MIMO which operate at 2.4 and 2.6 GHz for Wireless Local Area Network (WLAN) and Long Term Evolution (LTE). The system radiation pattern is configured using an Arduino Microcontroller to driven PIN diode to switch he beam. Simulations and measurements are in good agreement with the configuration of the single antenna and 2×2 and 4×4 MIMO. The antenna is operational between 2.387 and 2.628 GHz, whereas the simulated and measured reflection coefficients are obtaining at least -24.3 dB. The MIMO antenna designed to improve data communication, especially in mobile communication systems.

99mTc-sestamibi and 131I whole-body scintigraphy and initial serum thyroglobulin in the management of differentiated thyroid carcinoma.

Our findings suggest that, compared with 131I scanning, 99mTc-sestamibi scanning is less sensitive in detecting thyroid remnants and lung metastases but appears to be more useful in the detection of lymph node disease before initial 131I treatment.

COMPUTERISED TURKISH VERSIONS OF TESTS FORCENTRAL AUDITORY PROCESSING DISORDER

Background To detect central auditory processing disorder (CAPD), a test battery is needed that probes the integrity of the central auditory nervous system and describes its response parameters. The audiologist needs to select a well-designed test battery that examines a variety of auditory performance areas. Computer-controlled adaptive tests are recommended because they maximise test efficiency and minimise floor and ceiling effects as well as minimising memory load. In order to increase test efficiency and minimise difficulties and training, we adapted computerised versions of the Frequency Pattern test and the Duration Pattern test. Material and Methods The present study was conducted at Hacettepe University, Turkey, in the Faculty of Medicine’s Otorhinolarnygology Department, Audiology and Speech Pathology Unit. In total, 80 children (43 girls, 37 boys) aged between 7 years 0 months and 11 years 11 months were recruited. Each participant completed an informed consent form and a biographical survey prior to the tests. All tests were administered according to instructions at a comfortable listening level on a calibrated laptop computer which delivered a ‘Frequency Pattern’ test and a ‘Duration Pattern’ test. Results Normative test results are presented. Scores obtained by both tests were evaluated as percent scores for clinical study. Conclusions We adapted the computerised versions of the Frequency Pattern and Duration Pattern tests. Norm percent scores were obtained. We are continuing development of a computerised test battery that will include “gaps in noise” and “dichotic digits” tests using touch-screen protocols.

Analysis of stress-structural collapse mechanism of columnar jointed basalt under high stress

Columnar jointed rock mass with unique joint network structure is a special type of jointed rock mass, which is a binary structure composed of high strength ‘basalt block’ and specific ‘dominant joint’. Relaxation, opening and slippage of columnar jointed surfaces and disintegration of columns occur easily during excavation under high ground stress, which eventually lead to disastrous collapses in columnar jointed rock mass. The construction safety of underground engineering under high stress is severed restricted by it. By combining acoustic wave, borehole camera and other integrated in-situ testing technology and numerical simulation, the mechanism of stress-structural collapse in columnar jointed rock mass under high stress is studied based on multiple columnar jointed rock mass collapses at left bank tailwater connection pipe of Baihetan hydropower station. The proposed controlling measures of excavation and support are also provided. The key of columnar joined rock mass collapse is the redistribution of stress in surrounding rock mass after the excavation and the strong unloading relaxation of columnar joined basalt, which causes the opening of its internal joint surfaces and structural deterioration, result in the disintegration of basalt columns. Thus, the chain catastrophic process of continuous unloading relaxation and progressive collapse of columnar jointed rock mass is induced. The research can provide reference for the prediction and control of deformation and failure of jointed rock masses in underground engineering under high geo-stress.

EAUWSeg: Eliminating annotation uncertainty in weakly-supervised medical image segmentation

Weakly-supervised medical image segmentation is gaining traction as it requires only rough annotations rather than accurate pixel-to-pixel labels, thereby reducing the workload for specialists. Although some progress has been made, there is still a considerable performance gap between the label-efficient methods and fully-supervised one, which can be attributed to the uncertainty nature of these weak labels. To address this issue, we propose a novel weak annotation method coupled with its learning framework EAUWSeg to eliminate the annotation uncertainty. Specifically, we first propose the Bounded Polygon Annotation (BPAnno) by simply labeling two polygons for a lesion. Then, the tailored learning mechanism that explicitly treat bounded polygons as two separated annotations is proposed to learn invariant feature by providing adversarial supervision signal for model training. Subsequently, a confidence-auxiliary consistency learner incorporates with a classification-guided confidence generator is designed to provide reliable supervision signal for pixels in uncertain region by leveraging the feature presentation consistency across pixels within the same category as well as class-specific information encapsulated in bounded polygons annotation. Experimental results demonstrate that EAUWSeg outperforms existing weakly-supervised segmentation methods. Furthermore, compared to fully-supervised counterparts, the proposed method not only delivers superior performance but also costs much less annotation workload. This underscores the superiority and effectiveness of our approach.

Network Morphology: a DATR account of Russian nominal inflection

In this paper we introduce a declarative approach to inflectional morphology, which we call Network Morphology, using the lexical representation language DATR. We show that we can account for a range of (Russian) data, for which previously various rule types were required, and can provide a more satisfying analysis than was previously available. First we outline the essential data (section 2), highlighting the problems they present. Section 3 introduces the basic tenets of Network Morphology. This draws heavily on DATR, which we present in outline in section 4. Next we reconsider the Russian declensional classes from this new perspective (section 5). We show how the approach described overcomes long-standing problems in an elegant fashion; the complexity of the data suggests that the approach adopted has implications well beyond Russian. We then tackle the complex problem of animacy in Russian, which exemplifies interesting regularities extending across declensional classes (section 6).

Toward Visualizing Subjective Uncertainty: A Conceptual Framework Addressing Perceived Uncertainty through Action Redundancy

Uncertainty is usually technically defined with associated metrics by visualization researchers. Next to this rather objective description, there is a subjective notion to uncertainty considering human experiences eliciting a response to the perceived uncertainty. This article aims to complement the default technical notion with a subjective perspective of uncertainty as we experienced. As a starting point, we introduce a conceptual framework aiming to explain the consequential life-cycle of subjective uncertainty in relation with visualization methods. The framework is illustrated by a case in which the redundancy of logged game play behavior is visualized to assist the discovery of subjective uncertainty. Our preliminary results show that visualizing the Shannon entropy of categorical action labels can be a promising method to probe subjective uncertainty.

CLOSED-FORM WORKING VOLUME COMPUTATION AND STRUCTURAL OPTIMIZATION OF REDUNDANT SERIAL ROBOT CHAINS DERIVED FROM ZONOTOPE THEORY

Application of Jacobian determinant of a nonredundant serial chain robot is a powerful and elegant way to deduce a closed-form computation of its working volume and the structural robot optimization. This approach highlighted in the 80's seems to have been neglected since then. We discuss under which joint conditions it can be considered and we show the possibility to extend this approach to redundant serial chain robots by substituting nonsquared Jacobian minors for squared-Jacobian determinant, thanks to the powerful so-called cubical dissection theorem peculiar to the zonotope theory. Two examples are considered: a 4R anthropomorphic regional arm structure and a 3R planar human digit-like structure.

A Note on Periodic Solutions of Second Order Nonautonomous Singular Coupled Systems

We establish the existence of periodic solutions of the second order nonautonomous singular coupled systems x ′′ + a 1 ( t ) x = f 1 ( t , y ( t )) + e 1 ( t ) for a.e. t ∈ [0, T ], y ′′ + a 2 ( t ) y = f 2 ( t , x ( t )) + e 2 ( t ) for a.e. t ∈ [0, T ]. The proof relies on Schauder′s fixed point theorem.

Blepharophimosis, ptosis, epicanthus inversus, telecanthus, amblyopia, and menstrual abnormality in sisters.

Two sisters with blepharophimosis, ptosis, epicanthus inversus, and telecanthus were examined. Both patients also had amblyopia in the right eye and menstrual abnormalities associated with elevated serum luteinizing hormone and follicle-stimulating hormone. The patients' father was suspected of having blepharophimosis and ptosis. It is possible that the blepharophimosis syndrome observed in this family is of autosomal dominant inheritance. We believe that this condition of blepharophimosis, ptosis, epicanthus inversus, telecanthus, amblyopia, and menstrual abnormality found in our patients may be rare, and that the menstrual abnormality in these patients may be associated with ovarial failure.

Divergent Roles of Histone Deacetylases in Human Adult Eythropoiesis.

Abstract Histone deacetylases (HDACs) plays a regulatory role in the expression and activity of transcription factors. Several studies suggested that HDACs influence the proliferation and differentiation of hematopoietic progenitors. Here, we studied the role of HDACs in human adult erythropoiesis, using a HDAC inhibitor FK228 [depsipeptide]. We first examined the effect of FK228 on the growth of erythroid progenitors by incubating G-CSF-mobilized peripheral blood CD34+ cells (500 cells/well) in semisolid serum-free cultures containing IL-3, SCF, or IL-3+SCF in the presence or absence of FK228. Addition of FK228 (0.5 ng/ml) to the cultures with IL-3 and SCF+IL-3 resulted in 32-fold and 12-fold increases, respectively, in the number of erythroid colonies that consist of CD36+ glycophorin A (GPA)low/negative cells, compared with the cultures without FK228. FK228 also increased the number of cells comprising erythroid colonies in the cultures with IL-3 and SCF+IL-3. No colony growth was detected with SCF and SCF+FK228. We next examined the effect of FK228 on BFU-E colony formation by incubating CD34+ cells with EPO or SCF+EPO in the presence or absence of FK228. While BFU-E colony formation was observed with SCF+EPO but not with EPO alone, addition of FK228 to the cultures containing SCF+EPO almost completely inhibited BFU-E colony formation. To further elucidate the effect of FK228 on BFU-E progenitors that grow in an EPO-dependent fashion, CD34+ cells were cultured for 7 days with SCF, Flt3L, TPO, and IL-3, and CD36+ cells were purified. Although BFU-E colony formation was induced by incubation of the CD36+ cells with EPO, it was strongly repressed by the presence of FK228. Suspension cultures of CD36+ cells revealed that viable cell numbers in the cultures with EPO+FK228 rapidly declined from 2 days of cultures, in contrast to an increase in the number of erythroid cells in the cultures with EPO. Annexin V/propidium iodide assay showed that, upon exposure to FK228, a remarkably higher fraction of the CD36+ erythroid progenitors expressed an annexin V+PI− phenotype, indicative of an apoptotic cell death, compared with the control cultures (71 ± 8% vs 4 ± 1%). On the other hand, even though FK228 blocked the BFU-E colony formation from CD34+ cells in the presence of SCF+EPO, FK228 did not significantly increase the population of cells that undergo an apoptotic cell death in CD34+ cells. These findings suggest that HDACs, while playing an essential role in SCF/EPO- and EPO-dependent erythropoiesis, negatively regulate the action of IL-3 and IL-3+SCF on the growth of early erythroid progenitors. Our results indicate that HDACs have diverse functions in human adult erythropoiesis.

Seminal and colostral protease inhibitors on leukocytes.

For detection of protease inhibitors from cow colostrum (CTI) and bull seminal plasma (BUSI I and BUSI II) on the surface of leukocytes, immunological methods were used. An agglutination and an immunofluorescence test demonstrated components on the surface of bovine, porcine and ovine granulocytes and lymphocytes which were immunologically identical with the protease inhibitors isolated from cow colostrum and bull seminal plasma. When antisera against (CTI, BUSI and BUSI II were absorbed by bovine and porcine liver, kidney and spleen homogenate or by bovine and porcine granulocytes or lymphocytes, the immunological tests were negative.

Dualism and economic stagnation: can a policy of guaranteed basic income return mature market economies to les Trente glorieuses?

The starting point of this chapter is an analysis of the original 19th-century classical dualistic structure of emerging industrial economies associated with a decoupling between real wage and productivity growth. This is followed by a description of how this gap disappeared during the Golden Age period of les Trente glorieuses and then re-emerged after the 1970s. This is done with the purpose of providing a framework for discussing some of the literature on guaranteed income programmes as promoted by both mainstream and heterodox economists. As is well known, proposals in favour of guaranteed income have become fashionable in recent times to address this growing income polarisation that has become endemic in mature industrial economies, and this chapter offers a critique of these proposals from a Polanyian perspective. While supporting the principle of a universal basic income as a means to establish a social subsistence floor, it is argued that a guaranteed income policy without also a societal commitment to full employment may trigger mechanisms that could actually strengthen labour market decoupling.

Exploring the Antioxidant, Antimicrobial, Antidiabetic, and Anticancer Properties of <i>Capsicum annuum</i> L. (Samandağ Pepper): Biochemical and In Silico Insights

Abstract Capsicum annuum L. species from the Samandağ district of Hatay/Turkey was used in our study. Phytochemical analysis of seed and fruit ethanol extracts of this plant was carried out by GC‐MS method. Total Antioxidant Status (TAS) and Total Oxidant Status (TOS) levels were determined to calculate the Oxidative Stress Index to determine antioxidant activity. MIC method was used to evaluate antimicrobial properties against pathogenic bacteria and fungi. Anticancer activity was determined by the XTT assay on breast (MCF‐7), lung (A549) and brain (C6) cancer cells and healthy fibroblast (WI‐38) cell lines. The effects of the extracts on acetylcholinesterase and α‐amylase activities were investigated. It was found that C. annuum fruit extract had a lower OSI value than the seed extract. Fruit and seed extracts showed antimicrobial activity on microorganisms at MIC values of 200 µg/mL. Molecular docking studies were conducted to analyze the antibacterial properties of plant active ingredients. These studies are chemical components that are determined to be more abundant in the plant extract. Thus, it aimed to evaluate the effects of active compounds on various bacterial species. The results revealed the potential antibacterial properties of plants and provided important data that these ingredients can be used in future treatment methods. The anticancer activity in all cancer cell lines was very high in both seed and fruit extracts with a selectivity index (SI) well above SI ≥ 3. Furthermore, no deleterious effect on healthy fibroblast (WI‐38) cells was observed. The extracts were found to decrease acetylcholinesterase activity but increase α‐amylase activity. As a result, these plant extracts were found to have anticholinergic potential.

Fiducial markers and spacers in prostate radiotherapy: current applications

Objectives To review the use of fiducial markers and spacers in prostate radiotherapy ( RT ). Materials and Methods We reviewed the literature on the use of fiducial markers to improve accuracy in delivery of RT for prostate cancer. We discuss the rationale for fiducials, the types available, the procedures and complications. We also reviewed the current literature on the novel use of spacers to reduce rectal toxicity during prostate irradiation. Results Prostate motion is a significant problem both during and between RT treatments. Intraprostatic fiducials allow accurate prostate localisation ensuring RT treatment accuracy. Insertion of gold fiducials are a cost‐effective marker that can be easily and quickly implanted and at least three fiducials are recommended. Severe complications from fiducial implantation are uncommon and marker migration is very rarely clinically significant. Spacers are a novel method to distance the rectum from the prostate during RT , reducing acute rectal toxicity, and have no detrimental impact on health‐related quality of life. Conclusions Intraprostatic fiducials are now standard of care when delivering prostate RT and early data shows benefit of spacers in reducing RT rectal toxicity.

A Method Based on Riccati Equation for the Vibration Analysis of Rods with Variable Cross-Sections

In this study, the longitudinal vibration of rods with variable cross-sections is studied. For the analytical solution of the problem, a new analytical method based on a recently developed method on the Riccati differential equation is utilized. The governing equation is reduced to Hill’s type second-order ordinary differential equation. The transformed equations can readily be solved analytically for various cases according to the method. Seven cases have been considered, and the frequency equations for each case have been obtained. According to the method developed, the problem is solved in the simplest way. By using the present method, the reader can readily decide whether the problem is solved analytically or numerically. The present method can solve the problem of longitudinal vibration of rods having cross-sections of arbitrary shape. Finally, the method is also applied to the longitudinal vibration of stepped rods. Mode shapes are plotted for special values.
