Butson-type complex Hadamard matrices and association schemes on Galois rings of characteristic 4
Authors: Ikuta Takuya , Munemasa Akihiro 
Published: January 2018

Abstract
We consider nonsymmetric hermitian complex Hadamard matrices belonging to the Bose-Mesner algebra of commutative nonsymmetric association schemes. First, we give a characterization of the eigenmatrix of a commutative nonsymmetric association scheme of class 3 whose Bose-Mesner algebra contains a nonsymmetric hermitian complex Hadamard matrix, and show that such a complex Hadamard matrix is necessarily a Butson-type complex Hadamard matrix whose entries are 4-th roots of unity.We also give nonsymmetric association schemes X of class 6 on Galois rings of characteristic 4, and classify hermitian complex Hadamard matrices belonging to the Bose-Mesner algebra of X. It is shown that such a matrix is again necessarily a Butson-type complex Hadamard matrix whose entries are 4-th roots of unity.

Published: January 2018

Abstract
We continue our systematic search for symmetric Hadamard matrices based on the so called propus construction. In a previous paper this search covered the orders 4v with odd v ≤ 41. In this paper we cover the cases v = 43, 45, 47, 49, 51. The odd integers v < 120 for which no symmetric Hadamard matrices of order 4v are known are the following: 47, 59, 65, 67, 73, 81, 89, 93, 101, 103, 107, 109, 113, 119. By using the propus construction, we found several symmetric Hadamard matrices of order 4v for v = 47, 73, 113.

Published: January 2018

Abstract
Consider the recursion g0 = a, g1 = b, gn = gn−1 + gn−2, n = 2, 3, . . . . We compute the Frobenius norm of the r-circulant matrix corresponding to g0, . . . , gn−1. We also give three lower bounds (with equality conditions) for the spectral norm of this matrix. For this purpose, we present three ways to estimate the spectral norm from below in general.

Published: January 2018

Abstract
In this study we construct, in the category XAlg(R) / A of crossed A-modules of R-algebroids, the coproduct of given two crossed A-modules M = (μ : M → A) and N = (ɳ : N → A) of R-algebroids in two different ways: Firstly we construct the coproduct M ᴼ* N by using the free product M * N of pre-R-algebroids M and N, and then we construct the coproduct M ᴼ⋉ N by using the semidirect product M ⋉ N of M and N via μ. Finally we construct an isomorphism betweenM ᴼ* N and M ᴼ⋉ N.

Abstract
Copper coated steel wires (1–5 numbers) reinforced in LM13 aluminium alloy composites have been prepared using squeeze casting process. Microstructure of composites has been investigated and mechanical properties viz., hardness, tensile strength and ductility have been examined and reported. Dry sliding wear behaviour of composites has been investigated by varying sliding distance and load. Fracture surface of broken tensile specimens and worn surface of wear samples have been investigated using field emission scanning electron microscope (FESEM). The results reveal that copper coated steel wires reinforcement in LM13 aluminium alloy improves the mechanical properties and wear resistance. Average hardness values of 136 BHN and 96 BHN have been observed in steel wire and at the interface of steel wire and aluminium alloy, respectively. Tensile strength of composites increased up to 28% by reinforcing three copper coated steel wires in LM13 aluminium alloy. Dry sliding wear test results reveal that weight loss, wear rate and coefficient of friction decreased with increasing number of copper coated steel wires reinforcement in LM13 matrix. However, weight loss of samples increased with increasing sliding distance and load. LM13 aluminium alloy reinforced with five numbers of copper coated steel wires decreased the weight loss up to 69% as compared to LM13 aluminium alloy tested at 40 N load and a sliding distance of 2500 m. Fracture surface of composites shows broken steel wires and dimples are observed in LM13 matrix. Worn surface of composites shows fine and shallow grooves; whereas delamination is observed in LM13 aluminium alloy. In general, copper coated steel wire reinforcement in LM13 aluminium alloy exhibited better mechanical properties and wear resistance compared to matrix.
Late Antique Christian Law in the Eastern Roman Empire
Authors: Monnickendam Yifat 
Published: January 2018

To date, early Christian sources have drawn the scholarly attention of theologians, scholars of biblical commentary, and historians, but not of legal historians, presumably because such sources do not offer sufficiently substantial material for legal historical research. Nevertheless, a few studies have blended legal history and late antique Christianity, and an analysis of these studies shows they are based on a “centralist,” or “formalist–positivist,” conceptualization of law.In this paper I review the scholarship of legal traditions in the eastern Roman Empire— namely, Roman law and Greek legal traditions, the halakha in rabbinic literature, and the halakhic traditions in Qumranic literature and in the New Testament—and contextualize it within developments in legal theory and legal sociology and anthropology (that is, the rise of legal pluralism). This review shows that developments in legal theory, in legal sociology and anthropology, and in legal history of the late antique world are producing new paradigms and models in the study of late antique legal history. These new models, together with new methods in reading early Christian non-legal texts of the eastern Roman Empire, can be utilized in the study of early Christianity, thereby opening gateways to the study of its legal traditions and revealing independent legal traditions that have remained hidden to date.
Whole-Genome Sequence Accuracy Is Improved by Replication in a Population of Mutagenized Sorghum

Published: January 2018

AbstractThe accurate detection of induced mutations is critical for both forward and reverse genetics studies. Experimental chemical mutagenesis induces relatively few single base changes per individual. In a complex eukaryotic genome, false positive detection of mutations can occur at or above this mutagenesis rate. We demonstrate here, using a population of ethyl methanesulfonate (EMS)-treated Sorghum bicolor BTx623 individuals, that using replication to detect false positive-induced variants in next-generation sequencing (NGS) data permits higher throughput variant detection with greater accuracy. We used a lower sequence coverage depth (average of 7×) from 586 independently mutagenized individuals and detected 5,399,493 homozygous single nucleotide polymorphisms (SNPs). Of these, 76% originated from only 57,872 genomic positions prone to false positive variant calling. These positions are characterized by high copy number paralogs where the error-prone SNP positions are at copies containing a variant at the SNP position. The ability of short stretches of homology to generate these error-prone positions suggests that incompletely assembled or poorly mapped repeated sequences are one driver of these error-prone positions. Removal of these false positives left 1,275,872 homozygous and 477,531 heterozygous EMS-induced SNPs, which, congruent with the mutagenic mechanism of EMS, were &gt;98% G:C to A:T transitions. Through this analysis, we generated a collection of sequence indexed mutants of sorghum. This collection contains 4035 high-impact homozygous mutations in 3637 genes and 56,514 homozygous missense mutations in 23,227 genes. Each line contains, on average, 2177 annotated homozygous SNPs per genome, including seven likely gene knockouts and 96 missense mutations. The number of mutations in a transcript was linearly correlated with the transcript length and also the G+C count, but not with the GC/AT ratio. Analysis of the detected mutagenized positions identified CG-rich patches, and flanking sequences strongly influenced EMS-induced mutation rates. This method for detecting false positive-induced mutations is generally applicable to any organism, is independent of the choice of in silico variant-calling algorithm, and is most valuable when the true mutation rate is likely to be low, such as in laboratory-induced mutations or somatic mutation detection in medicine.
Control of Maize Vegetative and Reproductive Development, Fertility, and rRNAs Silencing by HISTONE DEACETYLASE 108

Published: January 2018

Abstract
Histone deacetylases (HDACs) catalyze the removal of acetyl groups from acetylated histone tails that consequently interact more closely with DNA, leading to chromatin state refractory to transcription. Zea mays HDA108 belongs to the Rpd3/HDA1 HDAC family and is ubiquitously expressed during development. The newly isolated hda108/hda108 insertional mutant exhibited many developmental defects: significant reduction in plant height, alterations of shoot and leaf development, and alterations of inflorescence patterning and fertility. Western blot analyses and immunolocalization experiments revealed an evident increase in histone acetylation, accompanied by a marked reduction in H3K9 dimethylation, in mutant nuclei. The DNA methylation status, in the CHG sequence context, and the transcript level of ribosomal sequences were also affected in hda108 mutants, while enrichment in H3 and H4 acetylation characterizes both repetitive and nonrepetitive transcriptional up-regulated loci. RNA-Seq of both young leaf and anthers indicated that transcription factor expression is highly affected and that the pollen developmental program is disrupted in hda108 mutants. Crosses between hda108/hda108 and epiregulator mutants did not produce any double mutant progeny indicating possible genetic interactions of HDA108 with distinct epigenetic pathways. Our findings indicate that HDA108 is directly involved in regulation of maize development, fertility, and epigenetic regulation of genome activity.

Published: January 2018

Introduction: Ascites is the fluid collection in the potential space of the peritoneal cavity. Alcoholic liver disease and intra-abdominal malignancy are two major etiologies behind it. Also, diagnosis of tuberculous ascites should be thought of due to endemicity. Cirrhotic patients at any time during the course of disease, invariably present with ascites which is one of the marker of decompensation. In our context, etiology behind ascites and its correlation with symptoms and clinical findings not yet studied, so present study is conceptualized.
Methods:This is a cross-sectional retrospective descriptive hospital based record review of patients presented with ascites in a tertiary center of Kathmandu. One hundred fourteen patients with ascites under regular follow up of Shree Birendra Hospital (SBH) were reviewed. Data regarding presenting complaints, examination findings, relevant investigations during first visit and final diagnosis were retrieved from our own record keeping and recorded information were then evaluated.
Results: Patients having ascites have myriad of symptoms and signs, commonest clinical feature being icterus (74, 64.9%). Most of them were anemic at presentation. Forty-two (36.8%) had high blood urea and 36 (31.5%) with high creatinine suggesting approximately 30-40% cases presented with deranged renal function test. Ninety-three (81.5%) had raised total serum bilirubin. Similarly, PT/INR derangements were in 74 (64.9%) and 57 (50%) suggesting deranged liver function. Serum albumin was less than 3.5 gram/deciliter in 83(72.8%) cases. Among the patients studied, 80 (70.1%) had high Serum-Ascites Abumin Gradient (SAAG) suggesting transudative type of ascites and rest 34 had low SAAG suggesting exudative type of ascites. Overall assessment revealed, majority of patients (71.05%) had Chronic liver disease (CLD) as the cause of ascites.
Conclusions: Ascites due to chronic liver disease was the main finding with etiology supported by laboratory findings. Significant numbers of the patients had deranged renal function on top of liver function derangement, so these parameters need to be properly taken care of.
Key Words: Ascites, liver cirrhosis, serum ascetic albumin gradient.
¿Se comparte la misma idea al utilizar el termino neoclasicismo?
Authors: Lozano Gerena Francisco Javier , Moreno Medina Jonathan 
Published: January 2018

La gran diversidad de acepciones que tiene el término economía neoclásica ha generado gran confusión entre los economistas y entre los estudiantes de economía. Dadas las implicaciones que tiene la utilización del lenguaje en la construcción y la enseñanza del conocimiento, es fundamental precisar de qué se habla cuando se hace referencia al término neoclásico. El objetivo de este artículo es mostrar que el término neoclásico no debería utilizarse con el fin de definir el cuerpo de ideas de la corriente principal sino, como lo emplean los historiadores de las ideas económicas, para describir el periodo comprendido entre 1870 y 1930.
Distribución funcional del ingreso y régimen de crecimiento en México y España
Authors: Luyano Cuevas Jose Raul , Herrera Revuelta Julio 
Published: January 2018

El propósito de las reformas neoliberales era estimular la inversión privada y las exportaciones para, de este modo, generar un mayor crecimiento y empleo. Sin embargo, estas modificaciones han generado una caída significativa de la participación de los salarios en el ingreso, tanto en países desarrollados, como en desarrollo, desde finales de la década de los setenta. La investigación de este fenómeno se hace desde la teoría poskeynesiana, pero realizando modificaciones a las funciones de inversión y exportaciones, de modo que la distribución funcional tenga un peso mayor en las estimaciones. Se encontró que las políticas de restricción salarial influyen negativamente en los componentes internos de la demanda, de manera que España resulta ser wage-led, y México profit-led.
Fragilidad financiera empresarial y expectativas de ingresos: evidencias de un modelo multiagentes

Published: January 2018

Este artículo vincula la fragilidad financiera de las empresas no financieras a la forma en que estas estiman los ingresos generados por sus ventas, en el marco de un modelo macroeconómico multiagentes. Siguiendo el enfoque monetario à la Schumpeter, el modelo se construye alrededor de la red de pagos y deudas entre agentes, así como de los subsecuentes saldos. En la economía artificial del modelo, las empresas experimentan fragilidad financiera en relación con los créditos otorgados por un banco, y utilizan diversos mecanismos adaptativos de estimación de sus ventas. El modelo es un sistema complejo, y se extraen resultados mediante simulaciones numéricas.
Maurice Allais sobre capital y equilibrio en la década de los cuarenta del Siglo XX, y sus implicancias para la teoría del equilibrio general
Authors: Dvoskin Ariel 
Published: January 2018

El presente artículo discute algunas dificultades insuperables que enfrenta la teoría marginalista del valor y la distribución para establecer una correspondencia con la observación, a la luz de las contribuciones de M. Allais en la década de los cuarenta del siglo XX, particularmente en “Traité d’économie pure” (1943/1994) y Économie et intérét (1947/1998). El artículo revisa las razones que llevan a Allais desde ofrecer la primera formalización del equilibrio general intertemporal (IGE) en una economía con horizonte finito en su Traité, hasta abandonar dicha noción de equilibrio en Économie, y adoptar en su lugar la noción de equilibrio estacionario. El artículo muestra: 1. Cómo esas razones expresan una contradicción entre el tratamiento del factor capital como un vector heterogéneo de mercancías al interior del IGE, y la capacidad de este de tener el rol tradicionalmente asignado al equilibrio como un centro de gravitación; y 2. Que el concepto de equilibrio estacionario tampoco puede ser aceptado, ya que también enfrenta a la teoría con un obstáculo insuperable en el tratamiento del capital, en este caso como un factor homogéneo, concebido como una magnitud de valor. Se concluye que el problema general del tratamiento del capital al interior del enfoque marginalista es irresoluble, y obliga a buscar un enfoque alternativo.
Walls, Alleys and Dead Ends: Street Walking as Design for Livability and Community

Published: January 2018

Modernist design creates urban spaces that exclude people and neighborhood cultures. Sustainable urban planning is built with human scale in mind. It is messy, but facilitates community. This paper traces the move to sustainable urban planning and suggests that it parallels the Christian understanding of a God who "sits high, but looks low."

This study uses qualitative research methods, descriptive depth interviews with 6 key informants and 11 informants support. The results showed that the mother initially did not understand and know about the GFCF diet. After got information from therapy, physician, psychologist and school teacher, they understanding of GFCF diet with is proved by mothers already know what foods must be limited. But the mother has not been able to implement a GFCF diet in everyday life as evidenced by the child is still often eat foods made from flour and milk. This is also evidenced in the form Food Frequency Quetionnaire Qulitative. Mother's level of understanding about the GFCF diet has been good, but from the 6 main informant could not do GFCF diet properly and strictly.
Keywords: Autism, Diet Gluten Free Casein Free, Flour and milk

ABSTRAK

Sekitar 60% penyandang autis mempunyai gangguan sistem pencernaan akibat alergi makanan. Gangguan sistem pencernaan ini mengakibatkan terjadinya kebocoran usus (Leaky Gut). Dampak leaky gut pada autis menyebabkan produksi hormon sekretin terhambat. Sebagai akibat, protein susu sapi (casein) dan gandum (gluten) tidak dapat dicerna dengan sempurna, karena protein tersebut tidak berubah menjadi asam amino tetapi menjadi peptida yang seharusnya dibuang lewat urin, akan tetapi pada anak autis peptida ini diserap kembali oleh tubuh dan masuk ke otak dan diubah oleh reseptor opioid menjadi morfin. Untuk itu anak autis harus membatasi asupan makanan dari gluten dan kasein, agar tidak membuat anak hiperaktif dan tantrum. Tujuan penelitian ini adalah mengetahui gambaran pemahaman ibu mengenai diet GFCF serta sejauh mana ibu menerapkan diet tersebut pada anaknya. Penelitian ini menggunakan metode penelitian kualitatif, jenis deskriptif dengan wawancara mendalam kepada 6 informan utama dan 11 informan pendukung. Hasil menunjukkan bahwa ibu pada awalnya tidak memahami dan mengetahui mengenai diet GFCF. Setelah mendapatkan informasi dari terapi, dokter, psikolog dan guru sekolah ibu menjadi paham

mengenai diet GFCF dengan dibuktikan ibu sudah mengetahui makanan apa saja yang harus dibatasi. Namun ibu belum bisa menerapkan diet GFCF di kehidupan sehari-hari yang dibuktikan dengan anak masih sering mengonsumsi makanan berbahan dasar tepung dan susu. Hal ini juga dibuktikan dalam form Food Frequency Quetionnaire (FFQ) Qulitative. Tingkat pemahaman ibu mengenai diet GFCF sudah baik, namun dari 6 informan utama belum bisa melakukan diet GFCF dengan baik dan secara ketat.
