Broadband power amplifier using hairpin bandpass filter matching network
Authors: Haider Muhammad Furqan , You Fei , Shi Weimin , Ahmad Shakeel , Qi Tian 
Published: November 2019

This Letter presents a new combination of a broadband power amplifier (PA) and an output microstrip hairpin bandpass filter. The filter is designed based on the fifth‐order Chebyshev low‐pass prototype element values. Even–odd mode impedance analysis is used to calculate the filter parameters. Meanwhile, only the fundamental impedance matching is considered for this design. Therefore, a highly selective bandpass response is obtained to provide a spurious‐free fundamental impedance matching. For verification, a broadband PA‐filter component across 1.9–3.1 GHz (48%) is designed and fabricated. Measurements have shown a drain efficiency of 48–56.6% with 39.3–40.5 dBm of maximum output power.
Commercial graphene nanoplatelets‐based tunable attenuator
Authors: Yasir M. , Savi P. 
Published: November 2019

A commercial graphene nanoplatelets‐based tunable attenuator is proposed. The attenuator comprises of a couple of microstrip lines connected through a gap where the commercial graphene nanoplatelets are drop casted. The transmitted signal through the microstrip line can be varied by an applied DC bias voltage that alters the graphene resistance. The DC resistance of commercially acquired graphene is higher than lab‐grown graphene and so is the resulting minimum attenuation of the transmitted signal. The proposed structure is designed to reduce both the minimum graphene resistance and the transmission. The resultant dynamic range of attenuation is more than twice as compared to other series attenuators designed with lab grown graphene nanoplatelets. The operating frequency of the attenuator is from 1 to 5 GHz with maximum dynamic range of attenuation almost 10 dB.
Prävention des Delirs auf der Intensivstation
Authors: Braune Stephan , Gurlit Simone 
Published: November 2019

AbstractA delirium in patients in the intensive care unit (ICU) is a manifestation of a severe acute dysfunction of the brain. It has a high prevalence and is associated with a relevant increase in morbidity and mortality. A cholinergic deficit and dopaminergic overactivity are considered to be a cause of delirium. Polypharmacy, which is often present before admission to the ICU, especially in the elderly, plays a key role as a trigger. The knowledge and identification of risk factors for delirium is a precondition for the early and effective prevention of delirium. The aim is the pre-operative or pre-interventional optimization of modifiable risk factors. Early and effective prevention of delirium can improve clinical outcome, reduce mortality, and positively impact long-term functional outcome. Non-pharmacological measures are always the basis for the prevention of delirium: maintenance of the day-night rhythm, sleep promotion at night and stimulation during the day, involvement of relatives, the avoidance of dehydration and malnutrition, and others more. They are pharmacologically accompanied by an effective analgesia and a target and symptom-oriented sedation with well controllable, as little as possible delirogenic substances. Interdisciplinary and interprofessional cooperation is essential so that preventive concepts significantly reduce the risk of delirium, even in high-risk patients.
Nicht pharmakologische und pharmakologische Therapie des Delirs
Authors: Reith Sebastian 
Published: November 2019

AbstractThe therapeutic management of delirium is based on two major columns. The cornerstone of therapy is the non-pharmacological intervention using a multifactorial approach including early mobilization, reorientation, improvement of cerebral and cognitive activity and the consequent establishment of adequate wake-/sleep cycles. Evidence for specific pharmacotherapy in delirium is currently rare, for both delirium prophylaxis as well as for definitive therapy of clinically apparent delirium. However, in clinical routine several substances are commonly used for the management of delirium particularly in a symptom-oriented choice. Moreover, regarding delirium prophylaxis the choice of sedativum has an important clinical impact on the incidence of delirium.

Authors: Abzieher Pia , Lipp Michael , Staats Johannes Hauke , Banaschewski Tobias , Driessen Martin , Karow Anne 
Published: November 2019

ZusammenfassungZiel der Studie war es, deutschlandweit adoleszenzspezifische Behandlungsmodelle zu untersuchen, die Umsetzung transitionspsychiatrischer Versorgung darzustellen und relevante Problembereiche in der Versorgung für Heranwachsende mit psychischen Erkrankungen zu identifizieren.
Methodik Es erfolgte eine fragebogenbasierte Querschnittserhebung (N = 26) krankenhausbasierter adoleszenzpsychiatrischer Behandlungsmodelle. Anhand von 28 Items wurden Daten zur Versorgungsstruktur, Zielgruppe und Therapieangeboten sowie spezifische Anforderungen der Adoleszenzpsychiatrie untersucht und deskriptiv ausgewertet.
Ergebnisse Es zeigt sich eine Zunahme adoleszenzspezifischer krankenhausbasierter Angebote in Deutschland. Diese sind durch diagnoseübergreifende und adoleszenzspezifische Therapieansätze und multiprofessionelle Arbeit gekennzeichnet. Überwiegend besteht ein Behandlungsangebot erst ab Volljährigkeit. Eine Minderheit der Therapieangebote ist in fachübergreifenden Kooperationsmodellen organisiert. Es werden strukturelle Defizite hinsichtlich Akut- und Krisenbehandlungen, sektorenübergreifender Zusammenarbeit und systematischer Transition berichtet.
Schlussfolgerungen Es besteht deutschlandweit ein wachsendes Interesse an der Entwicklung adoleszenzpsychiatrischer Behandlungsangebote. Die enge fachübergreifende Zusammenarbeit von Kinder- und Jugendpsychiatrie und Erwachsenenpsychiatrie ist zur Überwindung von Schnittstellenproblemen mit dem Ziel einer gelungenen Transition notwendig, aber bisher nicht flächendeckend implementiert. Um die Weiterentwicklung von Kooperationsprojekten zu ermöglichen, sollten strukturelle Hürden verringert werden.

Authors: Sabatino Joseph J. , Wilson Michael R. , Calabresi Peter A. , Hauser Stephen L. , Schneck Jonathan P. , Zamvil Scott S. 
Published: November 2019

SignificanceMultiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. CD8+T cells have been strongly implicated in MS pathogenesis, but it is unclear whether myelin is a CD8+T cell autoantigenic target in MS. This study demonstrated that while myelin-specific CD8+T cells are present at similar frequencies in untreated MS patients and healthy subjects, the proportion of memory and CD20-expressing myelin-specific CD8+T cells was increased in MS patients, suggesting prior antigen encounter. This activated phenotype was reversible as the memory and CD20-expressing populations of certain myelin-specific CD8+T cells were reduced following anti-CD20 treatment.
Retranslating Thucydides as a scientific historian
Authors: Jones Henry 
Published: November 2019

Abstract
The nineteenth century was a period of dramatic change in Europe for the idea of history. While from antiquity
through to the eighteenth century, historiography had broadly been considered an artistic and rhetorical activity, this view
gradually lost ground in the nineteenth century to an understanding of history as a science. This case study aims to explore how
these shifts in attitudes towards the proper aims and methods of history writing might have shaped the interpretation and
translation into English of Thucydides’ History of the Peloponnesian War, a work first written in classical Greek
in the fifth century BCE. The analysis is carried out by means of a corpus-based methodology which, I argue, can better enable
researchers to engage with each (re)translator’s overall presentation of the source through the production and interrogation of
concordances listing every instance of a given search item as it occurs within digitised versions of the target texts. This is
demonstrated through an investigation of the use of the term ‘fact(s)’ which reveals a striking divergence in interpretation
between the six translations, with Crawley’s (1874) History in
particular appearing to lend a significantly more objective and empirical tone to Thucydides in English.

Published: November 2019

Abstract
Proficient writing in English is a challenge for the linguistically diverse community college population. Writing research at the community college level is warranted in order to guide instruction and assist students in achieving higher levels of proficient writing. The current study examined the writing of three community college groups: native English Language students (L1, n = 146), English as a Second Language students primarily educated abroad (L2, n = 31), and English as a Second Language students who graduated from high school and lived in the United States for more than four years (Generation 1.5, n = 72). The writing samples were analyzed using Coh-Metrix to examine group differences in lexical, syntactic, and cohesion characteristics. Results indicated significant differences in syntactic and lexical measures among all groups, with small to large effect sizes. The majority of differences related to proficient writing characteristics were found between L1 and Generation 1.5 groups.

Abstract
In this article, we employ the perturbed Fokas-Lenells equation (FLE), which represents recent electronic communications. The Riccati-Bernoulli Sub-ODE method which does not depend on the balance rule is used for the first time to obtain the new exact and solitary wave solutions of this equation. This technique is direct, effective and reduces the large volume of calculations.

Published: November 2019

Abstract
We discuss one-dimensional Dirac oscillator, by using the concept doubly special relativity. We calculate the energy spectrum by using the concept doubly special relativity. Then, we derive another representation that the coordinate operator remains unchanged at the high energy while the momentum operator is deformed at the high energy so that it may be bounded from the above. Actually, we study the Dirac oscillator by using of the generalized uncertainty principle version and the concept doubly special relativity.
Polarized Debye Sheath in Degenerate Plasmas*
Authors: Shahmansouri M. , Misra A. P. 
Published: November 2019

Abstract

The force on a charged dust grain in a plasma due to polarization of thermal ions and degenerate electrons around the grain is derived in the limits of weakly relativistic and ultra-relativistic degeneracy of electrons. It is found that in both these cases, the magnitude of the polarization force is enhanced compared to that in classical plasmas. The influence of this force on dust-acoustic (DA) modes is examined and discussed. It is shown that the DA wave frequency in degenerate plasmas is significantly reduced compared to the classical DA mode.

Published: November 2019

Abstract

A design of ultrathin crystalline silicon solar cell with Si3N4 circular truncated cone holes (CTCs) arrays on the top is proposed. In this article, we perform an optical simulation of the structure. The finite-difference time-domain method is used to calculate the optical absorption of different periods, radius of top and bottom circles and depth of Si3N4 CTCs. The short-circuit current density generated by the optimized cells (30.17 mA/cm2) is 32.44% more than the value gained by control group (with flat Si3N4). Then adding a layer of back silver to allow us to better analyze optical absorption. Later, we simulate the optimization of the same configuration of different silicon thicknesses and find that our structure does enhance the light absorption. This work uses a combined path towards achieving higher photocurrent ultrathin crystalline silicon solar cells by constructing the texture of anti-reflection coating.

This work uses the Boltzmann transport model to study the thermal production of

and

in the quark gluon plasma (QGP) produced by

TeV Pb-Pb collisions. The

nuclear modification factors are studied in detail alongside the mechanisms of primordial production and the recombination of charm and anti-charm quarks in the thermal medium. The

binding energy is much smaller in the hot medium compared to the ground state; thus,

with middle to low

to inherit larger collective flows from the bulk medium. We quantitatively study the nuclear modification factors of both

and

in different centralities and transverse momentum bins for

TeV Pb-Pb collisions.

Abstract
Maximum Sustainable Yield (MSY) is a management exploitation that aims to maximize the catch but still maintain its sustainability. In this article, the authors try to build a model which have been modified from basic Lotka-Volterra model with addition logistic function to prey population and Holling Type II functional response to predator population as well as harvesting of both population. The equilibrium points and the stabilityvare done here through the linearization. Dynamical simulations are shown to illustrate the dynamics of the two populations. Based on the results of analysis and dynamical simulation, the MSY value can be achieved when the harvesting efforts does not exceed or equal the MSY value.

In this paper we discuss SIR mathematical of diphtheria transmission by simplify the assumptions and find parameters that give contribution to endemic and nonendemic condition. The model assumes that infected humans can heal by itself. We try to analyse what happen in this simplest mathematical model of diphtheria transmission even though in practise, it is not realistic and cannot eliminate the disease. We use Basic Reproduction Number to analyse the endemic equilibrium. We open discussion if this model can be expanded by adding more complex parameters and variables.

Published: November 2019

Abstract
Earthquake problems are a fascinating topic that discussed among the scientific and academic in the world, including of these is the parameter of a sensitivity. In this study, the sensitivity level of earthquake input motion in bedrock correlated with intensity arias and amplification occurring at the surface. The selected location of the study is an earthquake-prone area with the last record of a major earthquake in 2006, i.e., Yogyakarta Special Region. There are 3 (three) study areas with different geological environments. The analysis is determined by these steps: (1) Probabilistic Seismic Hazard Analysis/PSHA (2) disaggregation (3) selection of motion input and (4) wave propagation analysis to obtain a graph of Arias intensity and amplification value. All of those are aided by EzFrisk and DeepSoil software. The results of this study, i.e., the higher natural frequency at the site, then the lesser amplification developed. The highest amplification takes place at BH-04 which has the smallest natural frequency. On the other hand, the lowest value occurred at BH-02 on the highest natural frequency. There is a tendency that the smaller delta on the effective time arias intensity, the more significant amplification be occurred, except for Loma Prieta ground motion.
