A low-profile patch antenna for ultrawideband application

In this letter, a low profile stacked patch antenna is proposed for UWB operations. The antenna design is comprised of three patches; a 35° angularly folded patch feed (bottom patch), T-shaped patch (middle patch), and strip-loaded patch (top patch). The wide bandwidth is achieved with the integration of a 35° angularly folded patch feed with a T-shaped patch. The antenna's size is reduced by using the shorting wall technique. The existence of electromagnetic coupling between the T-shaped patch and strip-loaded patch further improves the impedance bandwidth. The design exhibits a compact electrical dimension of 0. 12λ×0. 14λ×0. 08λ, where λ is the wavelength of the lowest operating frequency. The measured results showed that the antenna can achieve a bandwidth of 107.46% (3.1-10.3 GHz). Acceptable gain, stable radiation patterns, and low group delay variation in the operating band are achieved as well. These measured results signify the effectiveness of the proposed antenna configuration in the context of UWB application.
Learning to feel like a lawyer: law teachers, sessional teaching and emotional labour in legal education

ABSTRACT Contemporary higher education, including legal education, incorporates complexities that were not identified even a decade ago. Law programs first moved from traditional content-focussed programs toward incorporating critique and legal skills. Many are now working toward recognising inclusion and student wellbeing as integral to law graduates’ professional identities and skillsets. Yet the professional dispositions law teachers require to teach in these environments are ostensibly at odds with traditional lawyering identities founded upon an ideal of rationality that actively disengaged from affect. This article draws on our teaching experience and data drawn from the Smart Casual project, which designed self-directed professional development modules for sessional law teachers, to identify the limits of a traditional teaching skillset in the contemporary Australian tertiary law teaching context. We argue that contemporary legal education demands considerable emotional labour and we present sample contexts which highlight the challenges law teachers face in doing what is expected of them. The article makes explicit the emotional labour that has often been implicit or unrecognised in the role of legal academics in general, and in particular, in the role of sessional legal academics.
The Effect of Behavioral Factors on Investment Decisions in Real Estate Sector in Nairobi County

Purpose- This study was intent on establishing the effect of behavioral factors on investment decisions in the real estate sector in Nairobi County. The behavioral factors explored for this study were herd behavior, representativeness, anchoring and overconfidence. Methodology- The study exploited descriptive research design to explicate how investors in real estate sector in Nairobi County make investment decisions from a behavioral finance point of view. Descriptive statistics and inferential statistics were used to scrutinize the data. Descriptive statistics adopted in this study included frequencies, mean, percentages and standard deviation. Additionally, inferential statistics of regression models and correlation analysis were used to examine the relationship of the study variables. The scrutinized data were presented in form of frequency tables and pie charts. Findings- The results of the study revealed that 53.71% of the respondents make use of the intuitions when evaluating investment decisions. The outcomes of the study further showed that representativeness, herd behaviour, anchoring and overconfidence have positive correlation coefficients of 0.21, 0.31, 0.16 and 0.32 respectively with the investment decisions in the real estate sector. The multiple R for the regression was 0.817, suggesting a strong positive correlation between the values that the model predicts and the actual values of the dependent variable. The R Square was 0.667 suggesting that about 66.7% of the variation in the real estate investment can be explained by the variation in the extent to which they are influenced by the behavioral factors. The Multiple R and the R Square suggest that behavioral factors exert influence on the investment decisions in the real estate sector. Implications- Behavioural factors analysis provides explanations on the trend of the investors in making critical investment decisions which portray a particular pattern of behaviour in the investment. Investors lack rationality when making decisions about their investments but rather make decisions based on emotions, feelings, mood and sentiments. Value- The study findings will enable investors to acquire skills necessary in eliminating various behavioral biases and increasing their rationality when making investment decisions in the real estate sector.
Posttranslational Modification of Glyceraldehyde-3-phosphate Dehydrogenase by S-Nitrosylation and Subsequent NADH Attachment (*)

Nitric oxide (NO)-related activity has been associated with an NAD-dependent modification of the glycolytic enzyme, glyceraldehyde-3-phosphate dehydrogenase (GAPDH). However, the mechanism by which NO effects covalent attachment of nucleotide and its role in regulation of enzyme activity are controversial. Recent studies have shown that S-nitrosylation of GAPDH (Cys) initiates subsequent modification by the pyridinium cofactor. Here we show that NADH rather than NAD is the preferred substrate. Transnitrosation from active site S-nitrosothiol to the reduced nicotinamide ring system appears to facilitate protein thiolate attack on the enzyme-bound cofactor. This results in attachment of the intact NADH molecule. Moreover, we find that S-nitrosylation of GAPDH is responsible for reversible enzyme inhibition, whereas attachment of NADH accounts for irreversible enzyme inactivation. S-Nitrosylation may serve to protect GAPDH from oxidant inactivation in settings of cytokine overproduction and to regulate glycolysis. NADH attachment is more likely to be a pathophysiological event associated with inhibition of gluconeogenesis.
Genetic subtyping of Listeria monocytogenes via multiple-locus sequence typing using iap, sigB and actA

Pulse field gel electrophoresis (PFGE) is widely used for listeriosis surveillance. Although this technique is effective for epidemiology, the data among laboratories are inconsistent. We previously reported a method for Listeria monocytogenes subtyping combined with sequence analysis of partial iap and whole genome restriction fragment length polymorphism (RFLP) using XbaI, ClaI (BanIII) and PstI. However, distinguishing subtypes was challenging, because the output comprised complicated fragment patterns. In this study, we aimed to establish a simple genotyping method that does not depend on visual observation, rather it focuses on multi-locus sequence typing (MLST) using three genes, iap, sigB and actA. Sixty-eight strains of L. monocytogenes including EGD-e as a reference strain were investigated to ensure consistency with previous data on the genetic characterization. All strains were grouped into 29 types by both analyses. Although there are some differences in classification, major clades included the same strains. Simpson’s indices of diversity (SID) by MLST and iap-RFLP-based typing were 0.967 (95% confidence interval [CI]: 0.955/0.978) and 0.967 (95% CI: 0.955/0.979), respectively. The discriminatory power of both methods can be considered almost identical. Compared with the results of 38 selected strains, the strains within the MLST clusters in this study coincided with those obtained using PFGE. Thus, the MLST strategy could help differentiate among L. monocytogenes isolates during epidemiological studies.
Public and Private Investment and Economic Growth: An Empirical Investigation

Abstract This paper provides new evidence to contribute to the current debate on the relative impact of public and private investment on economic growth and the crowding effect between the two components of investment in South Africa. Using annual data from 1970 to 2017, the study applies the recently developed Autoregressive Distributed Lag (ARDL)-bounds testing approach to cointegration. The study finds that private investment has a positive impact on economic growth both in the long run and short run, while public investment has a negative effect on economic growth in the long run. Further, in the long run, gross public investment is found to crowd out private investment, while its infrastructural component is found to crowd in private investment. The results of the study also reveal that both gross public investment and non-infrastructural public investment crowd out private investment in the short run. Overall, the study finds private investment to be more important than public investment in the South African economic growth process and that the importance of infrastructural public investment in stimulating private investment in the long run cannot be over-emphasized.
Development of a lightweight biped adult-size humanoid robot with connecting lever structure in RoboCup

The humanoid robot is a popular research topic in robotics. Especially, how to make the robot more like a human being not only behavior but also body structures always has been the main researching direction of all developers. However, before they started to research the kinematics and algorithm. Developers have to invest a huge amount of money in order to build the hardware. As a result, many developers without resource, can only work in simulation, not real robots. In this project, we are going to build legs of an adult-size humanoid robot (about 90cm height). In our design, the legs use a connecting lever structure that works similarly to the human muscle to deliver the force. In order to design the lightweight legs and feet, we also set up most of the heavy items compress around the hip part. The heavy hip approximate to human's core muscle group, it can be used to support the upper-body, keep balancing, drive the legs and reduce the load of the lower limbs. Therefore, our robot doesn't need to have strong or heavy limbs and is more human like. Eventually, we design and build the robot with lightweight legs and easy control center of mass. This helps us to reduce the strength of the servo motor and use low-cost servo motor only. We built humanoid robot legs with a weight of around 10 kg and 12 degrees of freedom. It only requires ten 60 kgf-cm and two 40 kgf-cm servo motors. The robot can accomplish the walking motion forward.
T cell receptor‐induced Fas ligand expression in cytotoxic T lymphocyte clones is blocked by protein tyrosine kinase inhibitors and cyclosporin A

Fas/APO‐1 is a member of the tumor necrosis factor receptor family of proteins, that induces apoptosis when cross‐linked with monoclonal antibody (mAb) or with its physiological ligand. Recently, both a perforin‐based and a Fas‐based mechanism have been proposed to account for T cell‐mediated cytotoxicity. In the present study we used a murine CD8+ cytotoxic T lymphocyte (CTL) clone (KB5.C20) specific for H‐2Kb and a T cell receptor (TcR)‐negative variant of the same clone (2005−D4) to test (i) whether the same cell can exert both cytotoxic effector mechanisms and (ii) the role of TcR engagement in the induction of Fas‐based cytotoxicity. We demonstrate that both the TcR+ and TcR− clones were able to express the Fas ligand after stimulation with phorbol 12‐myristate 13‐acetate (PMA)/ionomycin, and that TcR engagement of the KB5.C20 clone by means of antigen‐bearing cells or of its anticlonotypic mAb (Désiré‐1), which leads to Ca2+‐dependent, presumably perforin‐based, cytotoxicity, was also able to induce Fas‐based cytotoxicity. In addition, using inhibitors we investigated the signal transduction pathway(s) involved in the induction of Fas‐based cytotoxicity and expression of the Fas ligand mRNA in the CTL clones. The involvement of src‐like protein tyrosine kinases (PTK) in Fas ligand induction through TcR engagement, was strongly suggested by inhibition with the src‐like PTK inhibitor herbimycin A. Inhibition of Fas ligand induction by genistein, a more general TPK inhibitor, even upon stimulation by PMA plus ionomycin, suggested the possible involvement of PTK activities downstream of protein kinase C (PKC) in Fas ligand induction in CTL. Finally, the implication of the Ca2+/calmodulin‐dependent protein phosphatase calcineurin in Fas ligand induction was demonstrated by the partial inhibition of Fas ligand induction with cyclosporin A. Thus, in CTL clones, Fas ligand expression is inducible by TcR engagement through a pathway similar to that involved in expression of some lymphokine genes.
Multisensory teamwork: using a tactile or an auditory display to exchange gaze information improves performance in joint visual search

In joint tasks, adjusting to the actions of others is critical for success. For joint visual search tasks, research has shown that when search partners visually receive information about each other’s gaze, they use this information to adjust to each other’s actions, resulting in faster search performance. The present study used a visual, a tactile and an auditory display, respectively, to provide search partners with information about each other’s gaze. Results showed that search partners performed faster when the gaze information was received via a tactile or auditory display in comparison to receiving it via a visual display or receiving no gaze information. Findings demonstrate the effectiveness of tactile and auditory displays for receiving task-relevant information in joint tasks and are applicable to circumstances in which little or no visual information is available or the visual modality is already taxed with a demanding task such as air-traffic control. Practitioner Summary: The present study demonstrates that tactile and auditory displays are effective for receiving information about actions of others in joint tasks. Findings are either applicable to circumstances in which little or no visual information is available or when the visual modality is already taxed with a demanding task.
Comparative evaluation of rumen‐protected fat, coconut oil and various oilseeds supplemented to fattening bulls

Growth performance, carcass and meat quality were determined in 36 fattening Brown Swiss bulls fed with maize silage‐hay‐concentrate based rations supplemented with fats and various oilseeds. The concentrate diet in the control group contained only barley and soybean meal, while the treated groups included, as partial replacement of the concentrate, rumen‐protected crystalline fat, coconut oil, whole crushed rapeseed, sunflower seed or linseed, providing additional 3% fat of total ration dry matter. Animals were housed in groups of six with one representative of each treatment in a monofactorial design and feed was offered using transponder controlled equipments. Daily gains were similar for control, protected fat, rapeseed and linseed treatments (1240 g/d on average), but were lower (P < 0.05) with sunflower seed (1135 g/d) and coconut oil (1038 g/d). Corresponding differences (P < 0.05) in carcass weights were observed. All fat supplemented groups had reduced rumen fluid protozoa counts (P < 0.05). Carcasses tended to be leaner with the fat supplements. Mostly no significant effects on other carcass quality (dressing percentage, conformation score) and meat quality traits (final pH, cooking loss, shear forces) as well as composition (dry matter, fat, collagen) occurred. Consequently, rumen protected fat and some oilseeds can be recommended to be fed to growing cattle as energy sources.
MAPI: Model for Analysis and Projection of Inflation in France

In this paper, we present the new model developed at Banque de France to forecast the Harmonized Index of Consumer Prices (HICP) and its components in France up to twelve quarters during the Eurosystem projection exercises. The model is a partial equilibrium model and is used for forecast purposes jointly with the macroeconomic model Mascotte. The model generates more accurate forecasts, conditional to Eurosystem common technical assumptions, than pure autoregressive models. We derive impacts of oil-price shock, exchange rate and wage shocks on headline and core HICP and find significant pass-through.
Strong directivity of ocean‐generated seismic noise

We measure direction and amplitude of ocean‐generated continuous seismic noise in the western United States. Slowness direction of the noise is determined using array beamforming, and particle motion direction from individual three‐component stations. We find two surprising results. First, the noise is highly monodirectional at all sites, regardless of coastal distance. A single narrow generation area dominates for most of the time period, interrupted by a second well defined direction during ocean swell events. Second, we find that a storm off the Labrador coast with not unusual wave heights generates coherent noise across the entire continent. We show the causal relationship between swells arriving at different North American coastal areas and the triggered microseisms in time‐lapse movies ( Animations 1 and 2 ) of ocean swells and concurrent microseisms. Our results have a number of implications for different fields of research. A useful by‐product of our finding that microseisms are a strongly directional noise source is the possibility of using automated processing of the continuous noise as a near real‐time check on station polarity and calibration problems, which would be a simply implemented indicator for the state of health of a seismic network. Consistent monodirectional noise may have an influence on seismic azimuthal measurements such as shear wave splitting. Most importantly, our findings should be taken into account in proposed studies which will use seismic noise as a proxy for ocean wave height in investigations of interdecadal climate change.
The Role of Palmitoylation for Protein Recruitment to the Inner Membrane Complex of the Malaria Parasite*

Background: Recruitment of peripheral proteins to the inner membrane complex (IMC) of the malaria parasite can be mediated by N-terminal acylation. Results: Characterization of substrate determinants and identification of an IMC-localized palmitoyl acyltransferase PfDHHC1. Conclusion: Residues close to palmitoylation sites interfere with specific IMC recruitment. PfDHHC1 represents an apicomplexan-specific PAT. Significance: Dissection of palmitoylation for protein recruitment to the inner membrane complex in P. falciparum. To survive and persist within its human host, the malaria parasite Plasmodium falciparum utilizes a battery of lineage-specific innovations to invade and multiply in human erythrocytes. With central roles in invasion and cytokinesis, the inner membrane complex, a Golgi-derived double membrane structure underlying the plasma membrane of the parasite, represents a unique and unifying structure characteristic to all organisms belonging to a large phylogenetic group called Alveolata. More than 30 structurally and phylogenetically distinct proteins are embedded in the IMC, where a portion of these proteins displays N-terminal acylation motifs. Although N-terminal myristoylation is catalyzed co-translationally within the cytoplasm of the parasite, palmitoylation takes place at membranes and is mediated by palmitoyl acyltransferases (PATs). Here, we identify a PAT (PfDHHC1) that is exclusively localized to the IMC. Systematic phylogenetic analysis of the alveolate PAT family reveals PfDHHC1 to be a member of a highly conserved, apicomplexan-specific clade of PATs. We show that during schizogony this enzyme has an identical distribution like two dual-acylated, IMC-localized proteins (PfISP1 and PfISP3). We used these proteins to probe into specific sequence requirements for IMC-specific membrane recruitment and their interaction with differentially localized PATs of the parasite.
Power saving algorithm for clustered Ad-Hoc networks (PSA-CAN)

Ad-hoc network is an infrastructureless network consisting of mobile nodes. So, the energy consumption of the interfaces can be significant. Reducing transmission power reduces the number of nodes reached but consumes less energy. The author propose a communication mechanism based on local beam search to organize the nodes of a single cluster in a tree leveled given a determined distance to each other.
Language and Gender: toward a Critical Feminist Linguistics

This article attempts to map out the development of language and gender research and studies from its early stage to recent trend. The early language and gender research is inclined to essentialist view; and it subsequently changes its direction into a more non-essentialist perspective. Both essentialist and non-essentialist perspectives on language and gender research are not necessarily affiliated with feminist linguistics. Their research findings mostly conclude that women’s language is inferior and women are not capable users of language. In a response to such “sexist” findings, various feminist scholars across the disciplines venture to rethink and redefine gender and language. Among many different approaches that they employ are two notable views, namely, the “dominance” and “difference” perspectives. One views man-woman differences in language use as a reflection of their power relation: the dominant and the subordinate. Meanwhile, the other sees this different linguistic use as a result of the different ‘sub-cultures’ of their social environment (Coates, 2000: 413 and also Litosseliti, 2006:27). This shift toward a critical feminist linguistics is in fact informed by the current theories in critical thinking and feminist perspectives. Keywords: language, gender, feminist perspective
Constrained Potential: A Characterisation of Mexican Microenterprises

This paper investigates the existence and nature of constraints prevailing among Mexican microenterprises. It provides inter-temporal insights by relying on firm-level data spanning from 1994 to 2012. A performance index is defined based on firm levels of capital stock and monthly profits, and is used to estimate the empirical probability of a business's success. The predicted values are used to classify every microenterprise into one of three categories: upper, middle, or lower segment. Overall, the study provides evidence of constrained productivity and capital misallocation. Specifically, middle-segment firms exhibit entrepreneurial features and their average marginal returns are 15 percent. Because this segment faces mainly external constraints, cost-effective interventions are plausible. Regarding the lower-segment firms, it is estimated that their average monthly marginal returns are 30 per cent, compared to 1 per cent for the upper segment. It is also shown that, over time, the share that middle-segment firms represent relative to all microenterprises increased from 16 to 22 percent. Lastly, the sources of variation in monthly profits among segments are explored using the Oaxaca-Blinder decomposition method.
