A Corpus-Based Study of Linguistic Deception in Spanish

In the last decade, fields such as psychology and natural language processing have devoted considerable attention to the automatization of the process of deception detection, developing and employing a wide array of automated and computer-assisted methods for this purpose. Similarly, another emerging research area is focusing on computer-assisted deception detection using linguistics, with promising results. Accordingly, in the present article, the reader is firstly provided with an overall review of the state of the art of corpus-based research exploring linguistic cues to deception as well as an overview on several approaches to the study of deception and on previous research into its linguistic detection. In an effort to promote corpus-based research in this context, this study explores linguistic cues to deception in the Spanish written language with the aid of an automatic text classification tool, by means of an ad hoc corpus containing ground truth data. Interestingly, the key findings reveal that, although there is a set of linguistic cues which contributes to the global statistical classification model, there are some discursive differences across the subcorpora, yielding better classification results on the analysis conducted on the subcorpus containing emotionally loaded language.

Hyperkalemia in Patients With Left Ventricular Assist Devices

Background: Both hypo- and hyperkalemia are associated with adverse events in heart failure patients. Their effects on patients with left ventricular assist devices (LVADs) remains unknown. Methods and Results: The cohort included consecutive patients undergoing LVAD implantation between 2014 and 2018. In all, 170 patients (median age 56 years; 117 males) were stratified according to serum potassium levels 1 month after implantation into 3 groups: hypokalemia (<3.5 mEq/L; n=15), normokalemia (n=146), and hyperkalemia (>5.0 mEq/L; n=9). Compared with the normokalemia group, the adjusted hazard ratios for 1-year mortality were 0.91 (95% confidence interval [CI] 0.21–3.92) for hypokalemia and 4.14 (95% CI 1.47–11.65) for hyperkalemia. In the hyperkalemia group, the prevalence of renin-angiotensin-aldosterone system inhibitors decreased and serum potassium levels normalized following the first month. Conclusions: Hyperkalemia was associated with increased mortality during LVAD support. Management of serum potassium needs further investigation.
Retrospective evaluation of the serum level of Vitamin D among COVID-19 patients in Al Madinah, Saudi Arabia

Coronavirus disease (COVID-19) is a new viral illness that affects not only the respiratory system but also leads to multiorgan involvement. Till now, no curative treatment is available; prevention is the only way to reduce the number of infected cases. Low serum level of vitamin D has been implicated in increased susceptibility to coronavirus infection and disease severity. However, there is no conclusive evidence as regards the role of vitamin D in COVID-19 infection and outcome. This study aimed to evaluate the serum level of Vit D in patients with COVID-19 and highlights its prognostic significance. A total of 109 COVID-19 patients' medical records were selected and retrospectively analyzed from Ohoud Hospital in Medina. Data collection was done in the period between 1/4/2020 and 22/2/2021 followed by statistical analysis. The median age for COVID-19 patients was 54 years old. The level of Vit-D was low in patients with COVID-19 with a median of 15.2 ng/ml. Serum ferritin was high in all COVID-19 patients with a median of 720.9 ng/ml. There was a significantly higher rate of developing severe forms of COVID-19 in males compared to females, P-value < 0.001. Serum vitamin D level was significantly lower in patients with COVID-19 compared to control with P-value < 0.001. More reduction in Vit-D level was detected in the severe form of COVID-19 (P-value 0.042). There were significantly lower levels of vitamin D and higher levels of ferritin in the server covid-19 cases, P-values of 0.018 and 0.001, respectively. Low serum Vitamin-D level was significantly associated with a higher risk of COVID-19 infection and a more severe form of the disease that may end by death. Vitamin D supplementation will provide a sufficient serum level of the vitamin that can prevent infection and or minimize COVID-19 severity. Keywords: COVID-19, vitamin D deficiency.
Performance of microcontacts tested with a novel MEMS device

Most practical MEMS actuators generate forces ranging from several micronewrons to one or two millinewtons. In order to explore the feasibility of low-resistance contacts for MEMS relays, we explored the force-resistance relationship for gold-gold microfabricated contacts. The effect of apparent contact area on resistance has also been examined for areas between 10 and 90,000 /spl mu/m/sup 2/. The force/resistance relationship of these fully-microfabricated flat microcontacts correlates well with traditional theory and previous experimental results. The average measured resistance varied between 20.5 m/spl Omega/ and 62.9 m/spl Omega/. Decreasing contact area and contact force lead to higher overall contact resistance. However, reducing the apparent contact area by orders of magnitude only had a marginal effect on the overall contact resistance, even when the apparent contact area was orders of magnitude less than the theoretical actual contact area (/spl pi/r/sub c//sup 2/). Furthermore, the force required for a stable microcontact was determined to be below 0.6 mN and therefore within the force range of a MEMS actuator.
Analytical current-voltage relations for compact SiGe HBT models. I. The "idealized" HBT

Based on the generalized integral charge control relation (GICCR), analytical current-voltage relations for "true" SiGe heterojunction bipolar transistors (HBTs) are derived, which are well suited for compact physically based transistor models. For this, the weighted minority charge in the collector, which proved to be of dominating influence at high current densities, is calculated from simple physical expressions. They contain the operating point as well as physical and technological parameters. The model equations, which serve as a basis for a new physically based compact SiGe HBT model called SIGEM, are verified up to high current densities by numerical device simulations. It is shown that not only the static behavior but also the small-signal parameters y/sub 21/ and y/sub 22/, which are more sensitive to potential model errors, are well described even far within the high-current region. In this first part of the paper, the work is restricted to HBTs with idealized and simplified doping profile. In the second part [2] it is shown how these equations can also he applied to HBTs with modified, more practical doping profiles and how the model parameters can be extracted.
The Effect of Organizational Culture and Employee Competence on Organizational Citizenship Behavior (OCB) with Work Motivation as a Mediation Variable (Case Study in Pekalongan District Land Office)

Having skilled employees is not enough to achieve the goals of an organization. What is most important is how to manage qualified employees to demonstrate their performance actively and engage in work and organizations with skills that cover all or even beyond their formal roles and responsibilities. Employees are expected by the organization, not in terms of completing tasks that conform to usual behavior but also behavior that provides performance that exceeds expectations or extra-role behavior. This extra-role behavior is also known as OCB. In this study, three variables can affect OCB, namely organizational culture, employee competence, and motivation as mediating variables. In measuring the relationship between the third variable and OCB, the researcher uses the SmartPLS application. And the results of the study show that organizational culture has a positive and significant effect on OCB, employee competence has a positive and significant effect on OCB, motivation can mediate the effect of employee competence on OCB but work motivation cannot judge the relationship between organizational culture and OCB.
Effect of Sperm Morphology on Normal Pregnancy

Background: Sperm morphology has been demonstrated to be a better predictor of fertilization potential than other semen analysis parameter Aim: The aim of this study is to determine the influence of the values of sperm morphology in men with normal sperm concentrations, according to the World Health Organization criteria, on the normal pregnancy. Patients and Methods: A Prospective study conducted in Salah Al-Din general hospital from January to May 2021. The study included 60 pairs of infertile couples and recorded male partner sperm morphology. Based on the sperm morphology of the semen sample collected for the initial evaluation, patients were divided into three groups: Group A (n:20): patients with sperm morphology values between 0% and 4%. Group B(n:20): between 5% and 14%. Group C(n:20): patients with sperm morphology greater than 14%. A study was excluded when mean female age was less than 25 or greater than 40 years to avoid confounding due to extremes in maternal age. Results: The study revealed that 35% of infertile men (group A) were smoker and compared with 20% of group B and 15% of group C, although the result was non-significant. The study showed that the mean of duration of infertility in group A was 45 year. The highest rate of infertile patients in the study (35%) was with duration of infertility for ≥5 year while only 10% was suffered from infertility less than one year, the study showed no significant differences among the studied groups regarding semen volume, sperm concentration, pH, rate of motility and WBCs cells. The study demonstrated that only 5% (1 of 20) of women who their husbands with abnormal sperm morphology (Group A) succeed to be pregnant normally during the period of the study compared with 30% of the group B and 65% of group
Co-evolutions of planning and design: Risks and benefits of design perspectives in planning systems

We develop an evolutionary perspective on spatial planning to investigate the potential contributions of design approaches to the coordination of spatial organization. After a re-articulation of the concepts of planning and design in this perspective, we distinguish six essential features of the planning/design dialectics in a community. These aspects ought to be understood when evaluating the risks and benefits of design perspectives in a planning system, and the potential for re-positioning design in planning. It is argued that relying on the rhetoric of any single actor or any single tradition of reflection on planning and design is deceptive, whereas the collective experience of learning and adaptation with actors and disciplines expands the scope of understanding and the pallet of possible adaptations.
How Transgender Adolescents Experience Expressing Their Gender Identity Around New People: An Interpretative Phenomenological Analysis

The literature suggests gender expression to be a key experience of transgender young people that may impact upon the development of their gender identity and psychological well-being. The present study aimed to explore participants’ experiences of expressing their gender identity around others, with a focus on interactions with new people (with whom they do not have an existing relationship). Semi-structured interviews were conducted with eight young people aged 16 to 17 who identified as male and were assigned female at birth. Three superordinate themes were identified: (a) using gender expression to shape identity; (b) experiencing and making sense of others’ responses; (c) a changing relationship with gender expression. The process of gender expression enabled participants to explore, develop, and strengthen social and self-identity, and had both positive and negative impacts upon their well-being. Initially gender expression seemed to be an effortful process in which participants felt pressured to conform to social expectations to be viewed as male, yet over time they navigated a way to express themselves in a manner that felt more comfortable and authentic. Findings highlight the need to facilitate young people to express and be affirmed in their gender identity, and to provide adequate support with the social experiences surrounding it.
A Numerical Steady State and Dynamic Study in a Data Center Using Calibrated Fan Curves for CRACs and Servers

This study presents the results of a detailed parametric study for a data center that is air cooled using a set of four CRAC units in a cold/hot aisle raised floor configuration. The fans of the CRAC units and the servers are calibrated using their practical characteristics fan curves. A commercial CFD code is utilized for this purpose in which the buoyancy forces are taken into account. The k-epsilon model and the Boussinesq approximation are used to model the turbulent airflow and the buoyancy effect, respectively. A dynamic model is developed to take into account the changes in flow rates and power dissipation in the data center environment. The current dynamic model does not take into account the thermal mass of the CRAC units or the servers. The effect of the CRAC fan speed, instantaneous change in power dissipation, tiles perforation ratio, and servers fan speeds on the total flow rate in the room and the inlet temperatures of the racks are investigated. In the transient model, we investigate the effect of different CRAC failure scenarios on the time history of the temperatures and the flow pattern in the data center. Time constants and safe time are estimated from this study. A fundamental understanding of the effect of different data center entities on the flow and the temperatures is developed. Interesting flow patterns are observed in the case of different CRAC failures that could be used to recommend general design guidelines.Copyright © 2013 by ASME
Market Wastes in Ibadan, Nigeria

Market sanitation has been a serious problem in major cities in Nigeria. This study describes the characteristics of wastes in 12 markets in Ibadan, the capital of Oyo State. The results indicate that the wastes comprise of over 68% of easily decomposable matter originating from food, leaves and paper. The wastes on an average showed 66.7% volatile substances, 2.1 % total Kjeldahl nitrogen, 1.6% total phosphorus (PO4), and 66.5% water content. The heavy metal contents were low in the single sample analysed. The possibility of converting such wastes into compost or animal feeds is suggested.
Fundamental investigation on a weakly magnetized ferrite absorber

Investigated are the matching characteristics of a magnetized ferrite absorber, which applies a weakly static magnetic field H/sub dc/ perpendicular to the sintered ferrite surface. Applying a static magnetic field to the ferrite enables the matching thickness of the absorber to be reduced from 8 mm in the absence of H/sub dc/ to 3 mm under 750 gauss. The matching frequency can also be changed broadly from 0.1 to 0.9 GHz by controlling ferrite thickness and H/sub dc/, simultaneously. These are well explained in terns of an nonsaturated permeability rather than tensor permeability. A thin magnetized ferrite absorber is realized using a ferrite with a large value of imaginary part of permeability when real part takes the value near 1.0. Matching frequency characteristics, whether broad or narrow, correlates closely with the slant of the curve for real part of permeability taking the value near 1.0 in the present frequency.
Resilience, Physical Activity, and Depression in Women Living With HIV in the San Francisco Bay Area: A Cross-sectional Study

Abstract There is a lack of literature on the effects of physical activity and depression on resilience in women living with HIV. This cross-sectional study examined the associations of sociodemographic factors, physical activity, and depression on resilience among 97 women living with HIV using linear regression models. Among these women, the mean resilience score was 70.7 (SD 16.3), the majority were insufficiently active (67.0%), and 45.4% had a Patient Health Questionnaire-9 score that indicated at least moderate depression. In a multivariable analysis, depression was negatively associated with resilience, and education was positively associated with resilience (p < .0001; p = .031). There was no significant correlation between physical activity and depression or resilience. An exploratory analysis did not indicate that depression mediated the relationship between physical activity and resilience. There is a need to address low levels of physical activity in women living with HIV. Interventions that address resilience and depressive symptoms may lead to improved mental health.
Creative Approaches to Environmental Learning: Two Perspectives on Teaching Environmental Art Education.

Environmental art education is growing in popularity in college and university programs as the arts begin to play a more prominent role in environmental and sustainability education. As this emerging field of study is an interdisciplinary endeavor that draws from the more established fields of visual art education and environmental education, environmental art education offers a means to increase the pool of potential learners to those in the arts and sciences, as well as diversify learning to ensure that it is memorable and authentic. This article describes two different approaches to the design of courses in this emerging field from the perspectives of both science and art educators, in hopes of providing direction on the development of curricula and pedagogy in environmental art education to other educators.
Numerical simulation of the Helicon Double Layer Thruster concept

During last years some laboratories obtained current free helicon double layers in experiments with both electropositive and electronegative gases. The current free double layer has potential application as a plasma thruster. Although considerable progress has been made, at the present time a number of aspects related to this phenomenon are still only partially understood. This paper presents results obtained by numerical simulation of double layer formation, stability and characteristics and explores the applicability of this concept to a space mission. The analysis has been conducted using a combination of 1-D and 2-D numerical codes. After the modelization of helicon source, the code is applied to simulate a simple plasma thruster.
Sexual Arenas, Alcohol (Ab)use, and Predatory Leadership: Facilitators of US Military Sexual Violence

Scholars argue that, historically, military women have not been considered equals to men in kinship and, therefore, have and will likely continue to experience more violence and greater fear of violence. The All-Volunteer Force (AVF) may even foster military sexual violence through sexual arenas in work-home spaces, alcohol (ab)use fueling sexual encounters between colleagues, and predatory leadership. This exploratory, grounded theory study captures insights of women veterans (n = 20) entering service between 1964 and 2016. Full inclusion is alleged, yet military women are objectified and “othered,” targets of sex-based attention, predation, and violence. From these data, military sexual violence (MSV) characterizes the AVF. To mitigate this, a renewed commitment to the US military’s historical ideal of altruistic care is necessary to realize the full inclusion of women and reduce if not eliminate military sexual violence.
Analysis and design of a multiple feedback loop control strategy for single-phase voltage-source UPS inverters

This paper presents the analysis and design of a multiple feedback loop control scheme for single-phase voltage-source uninterruptible power supply (UPS) inverters with an L-C filter. The control scheme is based on sensing the current in the capacitor of the load filter and using it in an inner feedback loop. An outer voltage feedback loop is also incorporated to ensure that the load voltage is sinusoidal and well regulated. A general state-space averaged model of the UPS system is first derived and used to establish the steady-steady quiescent point. A linearized small signal dynamic model is then developed from the system general model using perturbation and small-signal approximation. The linearized system model is employed to examine the incremental dynamics of the power circuit and select appropriate feedback variables for stable operation of the closed-loop UPS system. Experimental verification of a laboratory model of the UPS system under the proposed closed-loop operation is provided for both linear and nonlinear loads. It is shown that the control scheme offers improved performance measures over existing schemes, It is simple to implement and capable of producing nearly perfect sinusoidal load voltage waveform at moderate switching frequency and reasonable size of filter parameters. Furthermore, the scheme has excellent dynamic response and high voltage utilization of the DC source.
Assessment of irradiated TiO2 nanoparticles on the growth and nutritional components of broccoli

Broccoli is highly tremendously as it is enriched with healthy promoting phytochemicals. This research was undertaken to study the feedback of broccoli to different concentrations of un-irradiated and irradiated (50 kGy of gamma rays) titanium dioxide nanoparticles (TiO2NPs). Un-irradiated and irradiated titanium dioxide characterization was accomplished by FT-IR, XRD, TGA, SEM and TEM. Foliar spray of titanium dioxide was applied to the broccoli in regards to the results of the characterizations. The growth traits; plant height, leaves No. per plant as well as stem diameter of plants and physical quality of heads were measured. Also, nutritional components of heads were determined. The results detailed that vegetative growth and physical quality of heads positively responded to foliar application of titanium dioxide compared to those obtained from control and 50 ppm from irradiated titanium dioxide (ITiO2NPs) gave the highest values of all traits. Regarding to nutritional components of heads, the efficiency of photosynthesis increased by using TiO2 (un-irradiated and irradiated) specially, 50 ppm ITiO2NPs. Application of Ti significantly increased the osmolytes concentrations such as proline, total free amino acids and soluble sugars as well as the extracts of heads sprayed with TiO2NPs concentrations displayed a prospective DPPH free radical scavenging action. Likewise, absorption of other nutrient elements and amino acids pool increased by spraying TiO2NPs. It was found that there are several phytochemical constituents identified by GC-MS that contribute to the biological activity of the methanol extract of broccoli heads that were affected by the use of TiO2NPs. It is clear that from above results, the using of ITiO2NPs specially; 50 ppm stimulated growth, resulting in improved quality of broccoli heads which is ultimately reflected in productivity.
