Published: December 2018

AbstractThis paper presents the design of a compact dielectric resonator antenna for 2.4 GHz wireless local area network or industrial, scientific and medical (ISM) band applications. The antenna consists of four stacked layers of dielectric resonators along with a rigid structure of coplanar waveguide feed. The complete antenna is placed on a safety helmet conformably to develop a wearable system for rescue workers. The achieved −10 dB bandwidth at 2.4 GHz is 6.6% (2.33–2.49 GHz). The maximum gain achieved with this proposed dielectric resonator antenna is 3.74 dBi. “On head performance” of this proposed helmet antenna is also observed including human head model in the simulation.

AbstractIn this study, a modified curve fitting model (CFM) for cylindrical dielectric resonator antenna (DRA) exclusively using YIG resonator with excess Fe2O3 is proposed. The modified CFM is used to accelerate the analysis of YIG resonator antenna (YRA) without having to repeat the characterization process for similar resonator. Modification of CFM is done using least square method in which correlation and regression analyses are used. The modified equations of resonant frequency and Q‐factor are adapted for the YRA design using YIG resonator with excess Fe2O3 of 9%. Comparison between the simulation, measurement, and modified CFM results are very well matched.

AimsThe International Consultation on Incontinence has published an update of the recommendations for the diagnosis and management of urine incontinence (ICI2016). This manuscript summarizes the consultations committee—recommendations with regard to urodynamic assessment.MethodsExpert consensus on the basis of structured evidence assessment has been the basis of the consultations publication and has been summarized by the committee for this manuscript.ResultsPatients that are not satisfied with their initial management on the basis of their reported signs and symptoms of urinary incontinence, as well as all patients with neurological abnormalities that are potentially relevant for the function of the lower urinary tract, may very likely profit from objective diagnosis and staging and grading of their dysfunction, with urodynamic testing, regardless their age, vulnerability and/or comorbidities. The principles and technical innovations as well as the principal recommendations for the utilization of (invasive) urodynamic assessment for women, men, children, and vulnerable elderly, with or without neurogenic lower urinary tract dysfunction with urinary incontinence are provided in this abbreviated ICI recommendations‐document.ConclusionsThe ICI2016 committee on urodynamics presents an executive summary of the most important reasons and recommendations for the use of urodynamic investigations for patients with urinary incontinence.

AimsSpina Bifida (SB) is a rare congenital condition that frequently impairs the neurological control of both fecal continence and defecation. Several therapeutic strategies have been proposed but impact assessment is lacking. Our objectives were to quantify the symptomatic improvement and to determine the optimal strategy in this rare condition where randomized controlled trials are difficult to conduct.MethodsData were extracted from a prospective database. The present analysis focused on patients having undergone at least two gastroenterological assessments. A standardized therapeutic approach was used from the first visit. Improvement was quantified by the variation of quantified symptomatic scores.ResultsThe data of of 57 adults with SB (gender F/M: 30/27 [52.6/47.4%]; mean age: 33.8 [18.5] years) were extracted. After a mean follow‐up of 46 months, 23/57 patients (40.4%) had at least improvement of one point of the Cleveland Clinic Incontinence score (CCIS); 13/57 (22.8%) reported a significant improvement of continence (delta score >50%). Five of the twelve patients (41.6%) with CCIS < 5 at baseline became incontinent over time. The neurological level was not associated with a worse continence outcome. Work on stool consistency and transanal irrigation were the most useful strategies in those with significant improvement of continence.ConclusionsUsing conventional strategies, a benefit on fecal continence occurs in only one out of five patients suffering from Spina Bifida and continent patients at baseline can develop fecal incontinence over time. A strategy targeting improved control of defecation (transanal irrigation) and a standardization of follow‐up protocol might be beneficial.
Environmental effects on the charge transfer properties of Graphene quantum dot based interfaces
Authors: Osella Silvio , Knippenberg Stefan 
Published: December 2018

AbstractGraphene quantum dots (GQD) are interesting materials due to the confined sizes which allow to exploit their optoelectronic properties, especially when they interface with organic molecules through physisorption. In particular, when interfaces are formed, charge transfer (CT) processes can occur, in which electrons can flow either from the GQD to the absorbed molecule, or vice versa. These processes are accessible by modeling and computational analysis. Yet, the presence of different environments can strongly affect the outcome of such simulations which, in turn, can lead to wrong results if not taken into account. In this multiscale study, we assess the sensibility of the computational approach and compute the CT, calculated at interfaces composed by GQD and amino‐acene derivatives. The hole transfer is strongly affected by dynamic disorder and the nature of the environment, and imposes stringent descriptions of the modeled systems to ensure enhanced accuracy of the transfer of charges.
Green Approach for the Domino Reduction/Reductive Amination of Nitroarenes and Chemoselective Reduction of Aldehydes Using Fe/aq. Citric Acid/Montmorillonite K10
Authors: Nagi Reddy Koti Siva , Reddy Karra Purushotham , Sabitha Gowravaram 
Published: December 2018

AbstractWe have developed a new and mild method for the direct one‐pot reduction/reductive amination of nitroarenes with arylaldehydes using Fe/aq citric acid/montmorillonite K10 catalytic system under ambient conditions. This catalyst has excellent functional group compatibility and the reaction provides rapid access to a diverse range of secondary amines. Under the conditions, aromatic aldehydes are selectively reduced to benzyl alcohols in the presence of ketones. A concise and efficient approach to the synthesis of diverse range of 1,2‐disubstituted benzimidazoles has also been accomplished for the first time from 1,2‐dinitrobenzene and aromatic aldehydes using the above catalytic system. The method involves the domino nitro reduction/cyclization/reduction cascade.

Published: December 2018

AbstractThe bioreduction process, that utilizes the plant extracts, have been explored extensively as a green chemical route for the synthesis of metal nanoparticles due to their eco‐friendly protocol as well as versatility in the selection of various plant resources. Recent advances in this plant extract mediated biological process are the fabrication of functional nanostructures. Bioreduction mechanism catalyzes the combining process of metal nanoparticles with other kind of materials including metal, metal oxides, cellulosic, zeolite and carbon nanomaterials. Integrating metal nanoparticles with various materials offers new functional properties and improves their performance comparing to their pristine counterpart. In this review, plant‐based biochemical substances, which influence the metal ion into metal and their controlled nucleation on the surface of other kinds of materials are highlighted, and the future prospect of this bio‐based synthesis of functional nanostructures are discussed.
2‐(1,1‐dioxidobenzo[b]thiophen‐3(2H)‐ylidene)malononitrile (BTD) Based Styryl Chromophores‐ Solvatochomic and Computational Investigation of Linear and NLO properties
Authors: Bhagwat Archana A. , Sekar Nagaiyan 
Published: December 2018

AbstractLinear and nonlinear optical properties of the twelve styryl dyes are investigated using density functional theory (DFT). Range‐separated hybrid CAM−B3LYP and global hybrid BHandHLYP estimate high second order hyperpolarizability. Mean polarizability (α0), polarizability anisotropy (Δα), static first‐order hyperpolarizability (β0) and second hyperpolarizability (γ) were found to be overestimated in CAM−B3LYP than in BHandHLYP. As bond length alternation (BLA) increases first order hyperpolarizability increases. Multilinear regression analysis (MLR) shows the solvent basicity, polarizability and dipolarizabilty are responsible for absorption solvatochromism. The ratio of the dipole moments increases as donor strength and conjugation increases which support charge transfer. The figure of merit (FOM) and intrinsic hyperpolarizability found more in chromophores with dialkylamine donors. As the stability indicated by electrophilicity indices decreases the hyperpolarizability increases. Interrelationships between α0, β0 and γ were evaluated and it shows good linear fit. Absorption is red shifted and hyperpolarizability increases with the amplitude of the sine‐shaped potential along the conjugation chain. A high molecular electrostatic potential was observed in dyes containing 2‐piperidinothiophene donor.

Published: December 2018

Abstract
Atypical hemolytic uremic syndrome (aHUS) is a disorder characterized by thrombocytopenia and microangiopathic hemolytic anemia due to endothelial injury. aHUS is felt to be caused by defective complement regulation due to underlying genetic mutations in complement regulators or activators, most often of the alternative pathway. Mutations causing aHUS can be subdivided into two groups, loss of function mutations (affecting factor H, factor H-related proteins, membrane co-factor protein, and factor I), and gain of function mutations (affecting factor B and C3). As more information becomes available on the relationship between specific mutations and clinical outcome, complete genetic workup of aHUS patients becomes more and more important.
In this review, we will discuss the genetic background of aHUS, the role of complement for aHUS pathogenesis, and the different groups of specific mutations known to be involved in the pathogenesis of aHUS.
REPRESENTATION IN MODELS OF EPISTEMIC DEMOCRACY

Published: December 2018

ABSTRACTEpistemic justifications for democracy have been offered in terms of two different forms of information aggregation and decision-making. The Condorcet Jury Theorem is appealed to as a justification in terms of votes, and the Hong–Page ‘diversity trumps ability’ result is appealed to as a justification in terms of deliberation in the form of collaborative search. Both results, however, are models of full and direct participation across a population. In this paper, we contrast how these results hold up within the familiar structure of a representative hierarchy. We first consider extant analytic work that shows that representation inevitably weakens the voting results of the Condorcet Jury Theorem. We then go on to show that collaborative search, as modeled by Hong and Page, holds its own within hierarchical representation. In a variation on the dynamics of group search, representation even shows a slight edge over direct participation. This contrast illustrates how models of information aggregation vary when put into a representative structure. While some of the epistemic merits of democracy are lost when voting is done hierarchically, modeling results show that representation can preserve and even slightly amplify the epistemic virtues of collaborative search.
Calcardea junnei Gingerich, 1987 from the late Paleocene of North America is not a heron, but resembles the early Eocene Indian taxon Vastanavis Mayr et al., 2007
Authors: Mayr Gerald , Gingerich Philip D. , Smith Thierry 
Published: December 2018

AbstractWe revisit the holotype of Calcardea junnei Gingerich, 1987 from the latest Paleocene (Clarkforkian) of the Willwood Formation (Wyoming, USA). The species is based on a partial skeleton and was originally assigned to the Ardeidae (herons). As we show, this classification cannot be upheld and Calcardea Gingerich, 1987 more closely resembles the taxon Vastanavis Mayr et al., 2007 (Vastanavidae), a parrot-like bird from the early Eocene of India. Even though C. junnei is a large bird, its long wings and short tarsometatarsus argue against a predominantly terrestrial way of living, and the morphology of the tarsometatarsus and pedal phalanges instead suggest strong grasping feet. We conclude that an assignment of Calcardea to the landbird clade (Telluraves) is better supported than its classification into the waterbird clade (Aequornithes), which includes Ardeidae and other ‘ciconiiform’ and ‘pelecaniform’ taxa. Calcardea junnei is one of the oldest known representatives of Telluraves and its morphology shows plesiomorphic features, which contributed to its previous misidentification as a heron. Calcardea exhibits a distinctive osteology and affords a glimpse of a previously unknown late Paleocene avian morphotype.
SOME MODEL THEORY OF GUARDED NEGATION
Authors: BÁRÁNY VINCE , BENEDIKT MICHAEL , CATE BALDER TEN 
Published: December 2018

AbstractThe Guarded Negation Fragment (GNFO) is a fragment of first-order logic that contains all positive existential formulas, can express the first-order translations of basic modal logic and of many description logics, along with many sentences that arise in databases. It has been shown that the syntax of GNFO is restrictive enough so that computational problems such as validity and satisfiability are still decidable. This suggests that, in spite of its expressive power, GNFO formulas are amenable to novel optimizations. In this article we study the model theory of GNFO formulas. Our results include effective preservation theorems for GNFO, effective Craig Interpolation and Beth Definability results, and the ability to express the certain answers of queries with respect to a large class of GNFO sentences within very restricted logics.
Judicial constitutional comparativism at the UK Supreme Court
Authors: Lienen Christina 
Published: December 2018

AbstractIn 2008, Lord Reed in his paper ‘Foreign precedents and judicial reasoning: the American debate and British practice’ noted the lack of full scholarly consideration of judicial comparativism in the UK. Ten years later, judicial reference to foreign judgments is still a very common phenomenon in this jurisdiction, however very little has been written about it. This paper assesses the UK Supreme Court's constitutional law jurisprudence in light of the main themes and arguments underlying the international debate concerning judicial comparativism. I argue that: (i) the use of foreign law is constitutionally legitimate where clear statutory language is respected; (ii) transferability concerns are mitigated by the interwovenness of the global common law system; and (iii) methodology concerns are mitigated by the UK Supreme Court's flexible, humble approach, which applies careful scrutiny to the foreign authorities put before it. Foreign judgments, I conclude, are never followed blindly or arbitrarily, and perhaps this is why there is no domestic debate about judicial comparativism, not even in the constitutional sphere.
Effects of dairy shed effluent dry matter content on ammonia and nitrous oxide emissions from a pasture soil

AbstractAtmospheric emissions of nitrogen (N) from New Zealand dairy farms are significant but have the potential to be affected by manure management prior to land application. The current work examined whether reducing cattle manure dry matter (DM) from 0.16 high DM (HDM) to 0.06 low DM (LDM), to enhance infiltration and reduce ammonia (NH3) emissions when applied to grassland, would affect nitrous oxide (N2O) emissions. Pasture was cut, simulating grazing, and either amended with HDM (173 kg N/ha) or LDM manure (48 kg N/ha) or left unamended. Ammonia emissions from HDM manure were higher than from LDM manure, as a flux or as a percentage of total ammoniacal nitrogen (TAN, i.e. NH3 + NH4+) applied, due to more TAN being retained near the soil surface and the higher soil surface pH under HDM manure treatment. Cumulative N2O emissions over 37 days from HDM plots were higher than from the control but not from the LDM plots. After 5 days, the daily N2O emission rate was larger from HDM plots than from LDM and control plots. The N2O fluxes from LDM and HDM treatments did not differ, either as a proportion of TAN applied or as a proportion of total-N applied. Increasing DM contributed to reductions in both oxygen (O2) availability and relative gas diffusivity, and thus potentially N2O production. Under the conditions of the current study, lower manure DM content reduced NH3 emissions but did not increase cumulative losses of N2O.
Percutaneous pulmonary valve implantation in patients after Ross procedure: role of intravascular ultrasound

Published: December 2018

AbstractCoronary compression exclusion during right ventricle outflow tract stenting is recommended and potential oversight may be fatal. Balloon inflation in right ventricle outflow tract with simultaneous aortography can be inconclusive or falsely negative. We present a case of 27-year-old male post Ross operation qualified for percutaneous pulmonary valve implantation. Neither of the conventional views obtained provided a definite exclusion of coronary compression, therefore an intravascular ultrasound of the left coronary artery before and during balloon inflation in right ventricle outflow tract was performed. Acquired images allowed excluding potential constriction, thus a covered stent and pulmonary valve were implanted and the procedure was concluded. Two hours later, the patient complained of chest pain. Transthoracic echocardiography demonstrated a significant pericardial effusion. Retrospective analysis of the final angiogram revealed a possibility of subtle extravasation at the distal part of the homograft. A hybrid procedure consisting of additional covered stent implantation, pericardial drainage, and second pulmonary valve implantation was performed with an acceptable result. To conclude, in case of doubtful or unconvincing images obtained from aortography or selective angiography during balloon inflation in right ventricle outflow tract, intravascular ultrasound might be a feasible and useful technique. Signs of homograft rupture may be subtle, whereas symptoms of cardiac tamponade delayed. In selected patients percutaneous treatment of homograft rupture is achievable and beneficial.
Jerusalem vs. Mecca in Ibn Qutayba's Kitāb Aʿlām al Nubuwwa
Authors: MAZUZ HAGGAI 
Published: December 2018

AbstractThis article investigates one polemical issue, the substitution of Mecca for Jerusalem, in the writings of Abū Muḥammad ʿAbd Allāh b. Muslim b. Qutayba (828–889 ce). In his Book of the Signs of Prophethood (Kitāb Aʿlām al-Nubuwwa), Ibn Qutayba interprets five Biblical verses that speak of Jerusalem as actually alluding to Mecca. The investigation queries the quality of several Biblical allusions in Ibn Qutayba's work, probes Ibn Qutayba's reasoning in using them, and asks how they fit into the larger and longer-lasting polemic between Islam and Judaism concerning the identity of the son whom Abraham bound on the altar. It is found that the two issues—the place most sacred to God and the identity of the bound son—are strongly connected in the polemic between Islam and Judaism and between different schools of Islamic exegesis.
A VON NEUMANN ALGEBRA CHARACTERIZATION OF PROPERTY (T) FOR GROUPOIDS

Published: December 2018

For an arbitrary discrete probability-measure-preserving groupoid $G$, we provide a characterization of property (T) for $G$ in terms of the groupoid von Neumann algebra $L(G)$. More generally, we obtain a characterization of relative property (T) for a subgroupoid $H\subset G$ in terms of the inclusions $L(H)\subset L(G)$.
WHEN DEMOCRACY DISAPPEARS
Authors: Seamster Louise 
Published: December 2018

AbstractIn this case study, I look at Benton Harbor, Michigan’s tenure under a state-appointed “emergency manager,” with extensive local powers replacing all local elected government, and a single imperative to balance the city’s budget. The law, ostensibly race-neutral, wound up targeting almost all of Michigan’s cities with significant Black population. The law ultimately disenfranchised half the state’s Black population but only two percent of Whites. This law invalidates a basic civil right and prerequisite for urban political theory: electoral democracy. Who holds power in the urban regime when the state takes over? Drawing on forty-four interviews, observations and archival research, I argue aWhite urban regimegoverns without elected representation in this majority-Black city. The ideological framing of emergency management as “neutral,” and Black politics as “corrupt” or “self-interested,” provides the logic to blame Black governance for structural disinvestment and White-led extraction.
