Efficient Procedure to Design Large Finite Array and Its Feeding Network With Examples of ME-Dipole Array and Microstrip Ridge Gap Waveguide Feed

An efficient procedure to design a large planar array and its corporate feeding network is presented. The procedure is verified by <inline-formula> <tex-math notation="LaTeX">$8 \times8$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$16\times16$ </tex-math></inline-formula> arrays of magnetoelectric dipoles (ME dipole) fed by microstrip ridge gap waveguide (MRGW) through a narrow slot. This procedure is based on using the frequency-dependent effective input impedance at the port of each element, which includes the effect of the mutual coupling between the antenna elements, which is used to design the corporate feeding network. In addition, the far-field characteristics of the array parameters such as directivity, gain, and the radiation patterns are predicted using the pattern multiplication method including the mutual coupling. The results are verified with the full-wave numerical solution. The procedure requires limited resources and speed up the design cycle. In the presented examples, the array elements are directly excited by the MRGW, which provides more flexibility to design complicated feeding networks and allow for distances between the elements less than a wavelength. Therefore, grating lobes are avoided. To accommodate such constraints, special designs of the power dividers are performed to provide the symmetric location of MRGW lines to avoid coupling between the feeding network lines. Furthermore, a transition from waveguide WR-15 to the MRGW is proposed to differential feed of the array antenna. The <inline-formula> <tex-math notation="LaTeX">$16 \times 16$ </tex-math></inline-formula> array of ME dipoles has been fabricated. The measurement results show a 19% matching bandwidth (<inline-formula> <tex-math notation="LaTeX">$\vert \text{S}11\vert < -10$ </tex-math></inline-formula> dB) and measured gain above 30 dBi with radiation efficiency better than 71%, all within a common bandwidth of 56–66 GHz.
Reaction-diffusion Equations with Nonlinear and Nonlocal Advection Applied to Cell Co-culture

This thesis is devoted to the study for a class of reaction-diffusion equations with nonlocal advection. The motivation comes from the cell movement with segregation phenomenon observed in cell co-culture experiments. The first part of the thesis mainly develops the theoretical framework of our model, namely the well-posedness and asymptotic behavior of solutions in both single-species and multi-species cases.In Chapter 1, we show a single scalar equation with a step function kernel may display Turing and Turing-Hopf bifurcations with the dominant wavenumber as large as we want. We find the bifurcation properties of the homogeneous steady state is closed related to the Fourier coefficients of the nonlocal kernel.In Chapter 2, we study a two-species nonlocal advection model with contact inhibition when the viscosity equals zero. By employing the notion of the solution integrated along the characteristics, we rigorously prove the well-posedness and segregation property of such a hyperbolic nonlocal advection system. Besides, under the framework of Young measure theory, we investigate the asymptotic behavior of solutions. From a numerical perspective, we find that under the effect of segregation, the nonlocal advection model admits a competitive exclusion principle.In the last Chapter, we are interested in applying our models to a cell co-culturing experiment. To that aim, we choose a hyperbolic Keller-Segel model on a bounded domain. By utilizing the experimental data, we simulate a 6-day process of cell growth in a circular petri dish and discuss the impact of both the segregation property and initial distributions on the finial population proportions.
Alone in a Crowded Room: The Impact of Crowd Noise in Music Recordings on Social Facilitation, Mental Imagery, and Cognitive Processing

This study investigates the role of crowd noise in the elicitation of social facilitation, mental imagery, arousal, and cognitive resource allocation. Participants (N = 60) listened to 8 total songs, 4 where artificial crowd noise was used to simulate a live recording and 4 that were the untouched studio recordings. Results indicate that crowd noise does not elicit greater enjoyment or mental imagery, but it does elicit greater allocation of cognitive resources and lower arousal over time, indicative of social facilitation. These results indicate that crowd noise is better defined as a content feature rather than a structural feature.
Elastic Flexure of Young, Overlapping Basaltic Lava Flows Offshore the Galápagos and Hawaiian Islands: Observations, Modeling, and Thermal/Chronological Analysis

A recent multibeam bathymetry survey in the Galápagos archipelago revealed a novel observation between the islands of Santa Cruz and Santiago: a steep flexural moat formed between two volcanic flows, nearly 50 m deep and about 500 m wide. Submarine observations and elastic plate modeling are consistent with this feature forming after one inflationary flow overlapped another young flow, deflecting the underlying lava flow in what appears to be a classical elastic flexural pattern. We present a flexural analysis of this moat feature using a thin‐plate approximation to determine the effective elastic thickness of the underlying flow. Moreover, we propose that this elastic thickness serves as a proxy for the thickness of the cooling, solidifying upper crust of the lava flow at the time of deflection, a time‐dependent thermal property. This approach offers a chronological tool to put bounds on the elapsed time between two overlapping lava flows. We applied this method to the Galápagos moat to constrain the time history of its formation. Additionally, we identified and modeled seven additional flexural moat candidates in the Hawaiian archipelago and in the Galápagos using multibeam bathymetry. Elastic/thermal history analysis of these features yields relative time intervals between submarine lava flows ranging from a few years to about 600 years, which suggests that there is a critical time interval during which elastic deflection of the underlying lava flow may become “frozen in. ” This methodology may provide helpful constraints on the temporal relations between overlapping lava flows wherever they form in relatively rapid succession.
Mining Facebook data for Quality of Life assessment

ABSTRACT Research indicates that how individuals utilise language to express themselves reflects individual-level differences regarding psychosocial characteristics, including perceived Quality of Life (QoL). In this study, we apply a language modelling technique to the natural user-generated language from Facebook to examine associations between language expressed on Facebook and self-reported QoL. Specifically, we collected the user-generated language from a sample of 603 Facebook users (76.3% females), mined emerging text corpora using the LIWC closed-vocabulary approach, and examined associations between LIWC features and self-reported domain-specific QoL (Physical, Psychological, Social), and General QoL. In line with previous research, we found use of pronouns, negative emotions, death and sleep words, and use of profanity to be significantly associated with QoL. Next, we used the Random Forest algorithm to test the predictability of QoL dimensions based on LIWC features and posting activity statistics. The models achieved moderate predictive power (r ranging from .22 to .33), the Psychological and General QoL dimensions showing the highest accuracy. An alternative approach combining LIWC features, posting activity, and predicted scores for domain-specific QoL components showed increased accuracy when predicting General QoL (r = .43). Findings are discussed in light of previous literature. Suggestions for improving models in future studies are provided.
Disruption of TFIIH activities generates a stress gene expression response and reveals possible new targets against cancer

Disruption of the enzymatic activities of the transcription factor TFIIH by Triptolide (TPL) or THZ1 could be used against cancer. Here, we used an oncogenesis model to compare the effect of TFIIH inhibitors between transformed cells and their progenitors. We report that tumour cells exhibited highly increased sensitivity to TPL or THZ1 and that the combination of both had an additive effect. TPL affects the interaction between XPB and P52, causing a reduction in the levels of XPB, P52, and P8, but not other TFIIH subunits. RNA-Seq and RNAPII-ChIP-Seq experiments showed that although the levels of many transcripts were reduced, the levels of a significant number were increased after TPL treatment, with maintained or increased RNAPII promoter occupancy. A significant number of these genes encode for factors that have been related to tumour growth and metastasis. Some of these genes were also overexpressed in response to THZ1, which depletion enhances the toxicity of TPL and are possible new targets against cancer.
Hamiltonian-Driven Hybrid Adaptive Dynamic Programming

This article presents a model-based hybrid adaptive dynamic programming (ADP) framework consisting of continuous feedback-based policy evaluation and policy improvement steps as well as an intermittent policy implementation procedure. This results in an intermittent ADP with a quantifiable performance and guaranteed closed-loop stability of the equilibrium point. To investigate the effect of aperiodic sampling on the communication bandwidth and the control performance of the intermittent ADP algorithms, we use a Hamiltonian-driven unified framework. With such a framework, it is shown that there is a tradeoff between the communication burden and the control performance. We finally show that the developed policies exhibit Zeno-free behaviors. Simulation examples show the efficiency of the proposed framework along with quantifiable comparisons of the policies with different intermittent information.
Identifying barriers and effective community interventions to voluntary medical male circumcision in the Zambezi region

Voluntary Medical Male Circumcision (VMMC) is basically the surgical removal of foreskin of the penis. This is done for many reasons. However, cultural, religious and medical reasons are the most paramount for Male Circumcision (MC) around the world today. Needless to say, since the three randomized controlled trials on male circumcision in Kenya, Uganda and South Africa proved that VMMC can reduce the HIV transmission by at least 60%, this has become the main reason for MC, especially in sub-Saharan Africa (Woambe, 2003). VMMC has also proved to protect both men and women against diseases and infections among others: Sexually Transmitted Infections (STIs), cervical cancer and penile cancer. Subsequent to these realizations, the World Health Organization (WHO) and the United Nations Programme on HIV/AIDS (UNAIDS) recommended VMMC to 14 countries in Eastern and Southern Africa (including Namibia) with high Human Immunodeficiency Virus (HIV) prevalence rates and low MC prevalence rates, as an additional HIV prevention strategy (Woambe, 2003). However, since the roll out of VMMC services in these countries, fewer men have heed the call to go for VMMC as the achieved number of circumcised men at the country and regional levels is not promising any significant realization that would have a positive health impact on the population, especially in relation to the HIV pandemic. Nearly all these countries could not reach the set targets, Namibia included. Despite numerous interventions to scale up VMMC in priority countries, the MC prevalence rates are still low. For example, Namibia as a country set the target of 330 128 men to
VARIODE ENABLED FREQUENCY-RECONFIGURABLE MICROSTRIP PATCH ANTENNA WITH OPERATION BAND COVERING S AND C BANDS

A frequency continuous reconfigurable microstrip patch antenna with operation band covering S-band and C-band is introduced. The antenna consists of a central rectangular patch and four parasitic patches with a symmetrical structure, connected by four varactor diodes in the middle position of the edge of each patch. With help of HFSS microwave studio simulation, results have shown that, by altering the bias voltage on varactor diodes, the operated frequencies vary continuously within a wide range from 3.29 to 4.01 GHz and 5.35 to 7.00 GHz, which cover S-band and C-band. Further measurement, which verifies the simulation by reasonable agreement, has been carried out. Besides, this frequency reconfigurable antenna maintains broadside radiation and stable radiation pattern. Specifically, the gain is basically maintained at around 4.5 dBi with the working frequency increasing from 3.60 to 7.00 GHz. Compared with other frequency-reconfigurable antennas available in previous literature, the proposed antenna has advantages of a wide frequency tuning range, high frequency selectivity, simple and stable structure, low cost, and miniaturization, which make it a promising candidate as cognitive radio and future wireless communication systems.
The complete chloroplast genome sequence of purple mullein (Verbascum phoeniceum L.)

Abstract Verbascum phoeniceum, known as purple mullein or temptress purple, is a species native to Central Europe, Central Asia, and Western China. In the present study, the chloroplast (cp) genome of V. phoeniceum was assembled using genome skimming sequencing. The cp genome of V. phoeniceum is 153,348 bp in length comprising two copies of inverted regions (IR, 25,430 bp) separated by the large single-copy (LSC, 84,601 bp) and small single copy (SSC, 17,887 bp) regions. It encodes 114 unique genes, consisting of 80 protein-coding genes, 30 tRNA genes, and 4 rRNA genes, with 20 duplicated genes in the IR regions. Phylogenetic analysis indicates that V. phoeniceum exhibits a closer relationship with Scrophularia rather than Buddleja.
Building a Spanish surname list for the 1990s--a new approach to an old problem.

This paper describes a direct and reproducible method for creating an inventory of surnames characteristic of the Hispanic origin population in the United States. The individual surnames included in this inventory are created by combining distinct surnames into groups and then analyzing group responses to the 1990 Hispanic origin question. Both a long list and a short list can be purchased in electronic format. The material in this paper was originally presented at the 1994 Annual Meeting of the Population Association of America.

Pneumothorax after insertion of nasogastric tube

A 65-year-old man was admitted to the Intensive Care Unit (ICU) for invasive mechanical ventilation after a significant intraventricular bleed. When his nasogastric tube (NGT) was accidentally removed, a new NGT was inserted blind. The pH of the thick green aspirate was under five and so enteral feeding was restarted. However, the patient subsequently deteriorated with rapidly worsening respiratory failure and invasive ventilation was required. An X-ray revealed misplacement of the NGT into the right lung with consolidation, pleural effusion, and pneumothorax. This highlights that indirect techniques to check NGT position (e.g., air insufflation and abdominal auscultation, aspirate appearance and pH) are unreliable. Even X-ray only detects misplacement after the event and mistakes have occurred because previous X-rays from the same patient have erroneously been reviewed. Only real-time visualization can prevent bronchopulmonary misplacement and the associated risks of pneumothorax and microbial contamination. The authors' current practice is therefore to use laryngoscopy, endoscopy, or fluoroscopy for insertion of all NGT in patients in ICU with impaired airway protective reflexes.
Biofunctionalized Polymer Nanomaterials: Implications on Shapes and Sizes

Nanotechnology has been one of the most widely used tools in various industries such as pharmaceutical, food, and chemistry, among others, for the encapsulation of compounds or even microorganisms. However, an analysis of the methodologies or polymer matrices to be used is rarely generated, and these in turn contribute to the objective of the product that is intended to be designed. In addition to the evaluation of its physicochemical, optical, and rheological characteristics, and others, are a set of technological tools that allow predicting the stability of a colloid, however, some of the factors that have less importance as the effect of the synthesis process on the shape and size that a structure may have, studies have been carried out to evaluate this phenomenon, which has become a determining factor in the design of any nanoscale material.
A new ultra‐wideband miniaturized antenna with a double‐branch radiator

The antenna proposed in this study is a double‐branch radiator antenna. The radiator of this antenna is neither a conventional single‐branch radiator nor is it just a simple combination of 2 radiator branches. Moreover, a parallel resonance wideband feeding technology is used on the feed structure of the proposed antenna. The reference antenna in this study was a conventional single‐branch radiator antenna, which also uses the parallel resonance wideband feeding technology. A total of 3 resonant current modes are generated with the proposed antenna. The operating mechanisms of the 3 modes were analyzed in detail. The results showed that the impedance bandwidth was significantly enhanced with the simple modification. The impedance bandwidth reached 210 MHz (0.83‐1.04 GHz), which is 2 times that of the reference antenna and approximately 4 to 5 times that of a conventional planar inverted‐F antenna (PIFA).
Analysis of the urban heat island intensity based on air temperature measurements in a renovated part of Budapest (Hungary)

The ratio of buildings, streets, and other artificially covered areas are increasing in cities. Ferencváros is an inner district of Budapest, the capital city of Hungary. For the local government of the district it is an important goal in the framework of the urban development planning to increase the proportion of vegetation since green areas have a mitigating effect for the urban heat island (UHI) intensity. We carried out an in situ measurement program for air temperature and relative humidity with 24 measuring points in Ferencváros, and also completed a green area survey in the renovated part of the district. The main aim of this paper is to analyse the daily cycle and the spatial structure of the UHI intensity based
Data Journalism beyond Majority World Countries: Challenges and Opportunities

ABSTRACT This commentary reflects on the state of research on data journalism and discusses future directions for this line of work. Drawing on theory in international development and postcolonial studies, we discuss three critical pitfalls that we encourage future scholarship in this area to avoid. These include using a linear model of progress, in which journalists in Majority World nations struggle to ‘catch up’ to their Minority World counterparts because of the ‘obstacles’ they face; reproducing a simplistic split between the ‘West and the Rest’, thus missing the complex interaction of structures operating at different levels; and failing to examine journalistic agency due to an overemphasis on the technical structuring of the ‘tools’ used in data journalism. We also encourage scholars to engage in more comparative work rather than single case studies; increase dialogic communication between scholarship produced in, or about, different parts of the world; and incorporate more diverse methodologies with the aim of building theory. More broadly, we advocate for greater critical reflection upon—if not the challenging of—our dominant modes of thought in order to build more nuanced frameworks for explaining the complex causes, and potentially mixed effects, of data journalism around the world.
Antagonism and population dynamics of Acinetobacter baumannii from US military treatment centers

Antibiotic-resistant bacteria complicate many infections and can be difficult to eradicate from hospitals. The population dynamics and ecology of these organisms in the hospital setting, however, is not well understood. Here, we report extensive strain-based antagonistic interactions occurring in military clinical isolates of Acinetobacter baumannii, a bacterial species that causes many drug-resistant hospital-associated infections. Sequence-based phylogenetic analysis of isolates allowed for differentiation to two major clades, with one of the clades representing two closely related genetic groups. Antagonistic activity was detected using a spot-plate assay to test pairwise interactions of all isolates. Isolates exhibited extensive and diverse patterns of antagonism against other isolates. One major clade of isolates had a distinct change in antagonism phenotype between isolates that differed by one base pair out of ~1500bp sequenced, with consistent antagonism of one group of isolates by the other. Both the antagonistic and the sensitive group exhibited extensive drug resistance. The first isolate of the antagonistic group was cultured in May 2010. The proportion of isolates from the antagonistic group collected before and after July 2010 increased from 2% to 76%. The results of this early study of the ecology of hospital-associated bacterial populations are discussed in the context of the species ecology of bacteria in natural environments. This work is a potential starting point for investigations into ecological interventions for infection control in hospitals.
Bromodomain inhibition reveals FGF15/19 as a target of epigenetic regulation and metabolic control

Epigenetic regulation is an important factor in glucose metabolism, but underlying mechanisms remain largely unknown. Here we demonstrated that bromodomain-containing proteins (Brds), transcriptional regulators binding to acetylated histone, are potent modulators of glucose metabolism via the gut-liver farnesoid X receptor (FXR)-fibroblast growth factor 15/19 (FGF15/19) pathway. In vivo inhibition of Brd4 by the inhibitor JQ1 in mice strongly inhibited ileal expression of FGF15, resulting in decreased FGFR4-related signaling, increased glucose production in the liver and hyperglycemia. Adverse metabolic effects of BRD4 inhibition were reversed by overexpression of FGF19, with improvement in hyperglycemia. At a cellular level, we demonstrate that BRD4 binds to the promoter region of FGF19 in human intestinal cells; BRD inhibition by JQ1 reduces binding to the FGF19 promoter and downregulates FGF19 expression. Thus, we identify Brd4 as a novel transcriptional regulator of intestinal FGF15/19 in ileum, and a contributor to hepatic and systemic glucose metabolism.
The Clinical Relevance of Detection of BCR-ABL in an Asymptomatic Patient: A Case Report and Review of the Literature

Chronic myelogenous leukemia is associated with the hallmark BCR-ABL translocation. With the increase in sensitivity in methods detecting the BCR/ ABL copy number, a small percentage of healthy subjects have been found to harbor low levels of the Philadelphia chromosome without evidence of chronic myelogenous leukemia. We present a case of a 71 year old male who was incidentally found to have a BCR/ABL chromosomal translocation on bone marrow biopsy being completed for a marginal zone lymphoma. The patient had no hematologic abnormalities on complete blood count when the BCR/ABL translocation was detected. The patient was treated with imatinib and developed a major molecular response. Currently no data exists on what percentage of healthy subjects that harbor low levels of the Philadelphia chromosome will go on to develop CML. These patients pose a clinical dilemma with regards to if they should be treated and when treatment should be initiated.
