A study on the cinnabar-bottomed burials of the early Bronze Age
Authors: Zhang Guoshuo , He Jun 
Published: January 2020

Abstract
Bottoming burials with cinnabar emerged in Phase II of the Erlitou Culture of the Xia Dynasty, which might be an important step of the interment ceremony of the Xia people, especially the elites, with the meaning of laying foundations for the burials in order to bless the deceased in the afterworld. This funeral custom became more common, which might be because of the northward expansion of the Erlitou Culture into southern Shanxi that involved absorbing or replacing local cultural elements. In the early Shang Dynasty, cinnabar-bottomed burials continued to exist, which supports the traditional belief that “Shang people followed the regulations of Xia”. By the time of the late Shang Dynasty, the popularity of waist pit burials increased while the ability of the Shang people to control the cinnabar resource declined, and consequently we see fewer cinnabar-bottomed burials.

Rethinking the origins of animal domestication in China
Authors: Yuan Jing , Dong Ningning 
Published: January 2020

AbstractInitial animal domestication in early Neolithic China may have resembled the behavior of raising animals as pets for entertainment. During the domestication process, the ecological characteristics and living habits of each animal and the subjective demands of ancient people jointly led to the formation of animal raising behaviors for utilitarian purposes. These commensal interactions involved both the actions of ancient people and the cooperative reactions of the animals themselves. Domestication processes were gradual and involved multiple repeated and progressive co-evolutionary developments.
Anhydramnios, but prenatally normal kidneys: renal tubular dysgenesis – patient with mutations in the renin-angiotensin system gene AGTR1
Authors: Kirch Naomi , Rocha Maria Linda , Wilke Mikosch , Bergmann Carsten , Schlembach Dietmar , Rossi Rainer 
Published: January 2020

Abstract

Background
Prenatally detected oligo- or even anhydramnios may – beside other reasons – be indicative for a diminished or absent urine production. The resulting clinical picture is a “Potter sequence” with arthrogrypotic joint contractions, a flat face and most importantly pulmonary hypoplasia. In severe cases this pulmonary hypoplasia can be life-limiting irrespective of the underlying lesion.

Case presentation
Our patient initially presented with anhydramnios and normal kidneys at external ultrasonography after 31 weeks of pregnancy. Following spontaneous birth after 37 weeks of gestation, the baby boy was born with all the clinical signs of a “Potter-sequence” along with a severe pulmonary hypoplasia leading to insufficient oxygenation and ventilation. Despite all measures taken, the child died after 8 h of life. Beside life-limiting pulmonary hypoplasia postmortem examination again confirmed macroscopically normal kidneys, but microscopy showed compact and variable sized glomeruli, numerically reduced and immature tubules, a structurally altered renal vascular bed and an expanded medullar interstitium. Immunohistochemical studies revealed the absence of proximal convoluted tubules, shortened proximal straight tubules beside an immaturity and dysmorphogenesis of the other segments of the nephron, and thus proved renal tubular dysgenesis (RTD) as the underlying disease. A homozygous mutation c.377G>C (p.Arg126Pro) in exon 2 of the AGTR1 gene was found, leading to the exchange of a highly conserved arginine to proline. This mutation has not been reported in public databases so far. As expected, both consanguineous parents were heterozygous for this mutation.

Conclusion
RTD has to be considered in an anuric fetus with apparently normal renal sonography in order to allow adequate prenatal counseling and – if indicated – palliative postnatal care.
Gridless Super-Resolution Direction-of-Arrival Estimation with Arbitrary Planar Sparse Array
Authors: Lu Aihong , Guo Yan , Yang Sixing 
Published: January 2020

AbstractTwo-dimensional (2D) direction-of-arrival (DOA) estimation with arbitrary planar sparse array has attracted more interest in massive multiple-input multiple-output application. The research on this issue recently has been advanced with the development of atomic norm technique, which provides super resolution methods for DOA estimation, when the number of snapshots is limited. In this paper, we study the problem of 2D DOA estimation from the sparse array with the sensors randomly selected from uniform rectangular array. In order to identify all azimuth and elevation angles of the incident sources jointly, the 2D atomic norm approach is proposed, which can be solved by semidefinite programming. However, the computational cost of 2D atomic norm is high. To address this issue, our work further reduces the computational complexity of the problem significantly by utilizing the atomic norm approximation method based on the concept of multiple measurement vectors. The numerical examples are provided to demonstrate the practical ability of the proposed method to reduce computational complexity and retain the estimation performance as compared to the competitors.
Designing Modern Compact Microstrip Planar Quadband Bandpass Filter for Hand Held Wireless Applications
Authors: Basit Abdul , Khattak M. Irfan 
Published: January 2020

AbstractThis paper presents a modern compact quad-band bandpass filter (BPF) using dual-mode stub loaded half wave (λ/2) resonators, where a couple of directly fed resonators are loaded with two identical inner resonators such that the direct fed resonators will act as feeding structure for the loaded resonators. Based on the proposed stub loaded resonators, a modern filter with seven transmission zeros (TZs) is designed by folding the two identical inner resonators. The proposed design has a symmetrical geometry, therefore even-odd mode analysis is used to predict the resonant frequencies of the passbands. The first and second passbands are obtained through fundamental odd and even modes respectively while the third one is achieved by placing loaded inner resonators in the proposed design. The second even harmonic of the direct fed resonators is utilized to achieve the fourth passband and is controlled by the stubs loaded at the middle of the resonators. The filter is simulated and fabricated for the purpose of validation, wherein a good agreement can be seen in both simulated and experimental results.

Published: January 2020

Abstract
The Heterogeneous photocatalysis, increasingly used in effluent purification, is attracting more and more attention by the development of new photocatalytic materials based on semiconductors deposited on various supports. In this work, TiO2 supported on cellulosic fiber was prepared and characterized by different analytical techniques such as X-ray Photoelectron Spectrometry and Brunauer-Emmett-Teller surface area. Its photocatalytic activity was investigated for the degradation of Solophenyl Scarlet BNLE (SS), an organic pollutant present in textile effluents. Several conditions were investigated such as adsorption under UV and visible irradiation, catalyst recyclability, the simulated effluent pH and the presence of H2O2 as an oxidant agent. Results showed that under UV light, the removal of SS decreased significantly with increasing initial dye concentration. For an initial concentration of 5 mg/L, SS degradation was reached more than 95 % after 2 hours of treatment (neutral pH, T = 20 °C). The supported TiO2 on cellulose remains effective over four cycles of dye treatment. In the presence of H2O2, the degradation process was inhibited with increasing the molar ratio [H2O2]/[SS]0 from 5 to 30. The kinetic modeling showed that the removal of this pollutant followed a pseudo-first-order model (Langmuir-Hinshelwood) with a regression coefficient (R2) value of 0.984.
On some automorphic properties of Galois traces of class invariants from generalized Weber functions of level 5
Authors: Eum Ick Sun , Jung Ho Yun 
Published: January 2020

Abstract
After the significant work of Zagier on the traces of singular moduli, Jeon, Kang and Kim showed that the Galois traces of real-valued class invariants given in terms of the singular values of the classical Weber functions can be identified with the Fourier coefficients of weakly holomorphic modular forms of weight 3/2 on the congruence subgroups of higher genus by using the Bruinier-Funke modular traces. Extending their work, we construct real-valued class invariants by using the singular values of the generalized Weber functions of level 5 and prove that their Galois traces are Fourier coefficients of a harmonic weak Maass form of weight 3/2 by using Shimura’s reciprocity law.
An optimal fourth-order family of modified Cauchy methods for finding solutions of nonlinear equations and their dynamical behavior
Authors: Liu Tianbao , Qin Xiwen , Li Qiuyue 
Published: January 2020

Abstract
In this paper, we derive and analyze a new one-parameter family of modified Cauchy method free from second derivative for obtaining simple roots of nonlinear equations by using Padé approximant. The convergence analysis of the family is also considered, and the methods have convergence order three. Based on the family of third-order method, in order to increase the order of the convergence, a new optimal fourth-order family of modified Cauchy methods is obtained by using weight function. We also perform some numerical tests and the comparison with existing optimal fourth-order methods to show the high computational efficiency of the proposed scheme, which confirm our theoretical results. The basins of attraction of this optimal fourth-order family and existing fourth-order methods are presented and compared to illustrate some elements of the proposed family have equal or better stable behavior in many aspects. Furthermore, from the fractal graphics, with the increase of the value m of the series in iterative methods, the chaotic behaviors of the methods become more and more complex, which also reflected in some existing fourth-order methods.
New error bounds for linear complementarity problems of Σ-SDD matrices and SB-matrices
Authors: Hou Zhiwu , Jing Xia , Gao Lei 
Published: January 2020

Abstract
A new error bound for the linear complementarity problem (LCP) of Σ-SDD matrices is given, which depends only on the entries of the involved matrices. Numerical examples are given to show that the new bound is better than that provided by García-Esnaola and Peña [Linear Algebra Appl., 2013, 438, 1339–1446] in some cases. Based on the obtained results, we also give an error bound for the LCP of SB-matrices. It is proved that the new bound is sharper than that provided by Dai et al. [Numer. Algor., 2012, 61, 121–139] under certain assumptions.

Sr[B5O7F3] was investigated by infrared spectroscopy. Photoluminescence spectra of the doped compound revealed an Eu2+ 5d-4f emission in the UV regime peaking at 371 nm with a full width at half maximum (FWHM) of 21 nm upon excitation at 239 nm, which proves a weak coordination of europium by the anionic fluorooxoborate network.
TheDrosophila melanogasterOrtholog of RFWD3 Functions Independently of RAD51 During DNA Repair
Authors: Carvajal-Garcia Juan , Gales Evan R , Ramsden Dale A , Sekelsky Jeff 
Published: January 2020

AbstractRepair of damaged DNA is required for the viability of all organisms. Studies in Drosophila melanogaster, driven by the power of genetic screens, pioneered the discovery and characterization of many genes and pathways involved in DNA repair in animals. However, fewer than half of the alleles identified in these screens have been mapped to a specific gene, leaving a potential for new discoveries in this field. Here we show that the previously uncharacterized mutagen sensitive gene mus302 codes for the Drosophila melanogaster ortholog of the E3 ubiquitin ligase RING finger and WD domain protein 3 (RFWD3). In human cells, RFWD3 promotes ubiquitylation of RPA and RAD51 to facilitate repair of collapsed replication forks and double-strand breaks through homologous recombination. Despite the high similarity in sequence to the human ortholog, our evidence fails to support a role for Mus302 in the repair of these types of damage. Last, we observe that the N-terminal third of RFWD3 is only found in mammals, but not in other vertebrates or invertebrates. We propose that the new N-terminal sequence accounts for the acquisition of a new biological function in mammals that explains the functional differences between the human and the fly orthologs, and that Drosophila Mus302 may retain the ancestral function of the protein.

Published: January 2020

Abstract
Forward genetics in model organisms has boosted our knowledge of the genetic bases of development, aging, and human diseases. In this experimental pipeline, it is crucial to start by inducing a large number of random mutations in the genome of the model organism to search for phenotypes of interest. Many chemical mutagens are used to this end because most of them display particular reactivity properties and act differently over DNA. Here we report the use of N-ethyl-N-nitrosourea (ENU) as a mutagen in the fission yeast Schizosaccharomyces pombe. As opposed to many other alkylating agents, ENU only induces an SN1-type reaction with a low s constant (s = 0.26), attacking preferentially O2 and O4 in thymine and O6 deoxyguanosine, leading to base substitutions rather than indels, which are extremely rare in its resulting mutagenic repertoire. Using ENU, we gathered a collection of 13 temperature-sensitive mutants and 80 auxotrophic mutants including two deleterious alleles of the human ortholog ATIC. Defective alleles of this gene cause AICA-ribosiduria, a severe genetic disease. In this screen, we also identified 13 aminoglycoside-resistance inactivating mutations in APH genes. Mutations reported here may be of interest for metabolism related diseases and antibiotic resistance research fields.
Red Light/Green Light, a Dual Fluorescent Protein Reporter System To Study Enhancer-Promoter Specificity in Drosophila
Authors: Camino Eric M , Weinstein Micheal L , List Mary P , Vellky Jordan E , Rebeiz Mark , Williams Thomas M 
Published: January 2020

Abstract
Enhancers activate gene transcription in spatial and temporal patterns by interactions with gene promoters. These elements typically reside distal to their target promoter, with which they must interact selectively. Additional elements may contribute to enhancer-promoter specificity, including remote control element sequences within enhancers, tethering elements near promoters, and insulator/boundary elements that disrupt off-target interactions. However, few of these elements have been mapped, and as a result, the mechanisms by which these elements interact remain poorly understood. One impediment is their method of study, namely reporter transgenes in which enhancers are placed adjacent to a heterologous promoter, which may circumvent mechanisms controlling enhancer-promoter specificity and long-range interactions. Here, we report an optimized dual reporter transgene system in Drosophila melanogaster that allows the simultaneous comparison of an enhancer’s ability to activate proximal and distal fluorescent reporter genes. Testing a panel of fluorescent transgenes in vivo, we found a two-protein combination that allows simultaneous measurement with minimal detection interference. We note differences among four tested enhancers in their ability to regulate a distally placed reporter transgene. These results suggest that enhancers differ in their requirements for promoter interaction and raise important practical considerations when studying enhancer function.
Göç Türküleri: Yunanistan Mübadilleri Örneği

Published: January 2020

1923 yılında Türkiye ve Yunanistan arasındaki
Mübadele Antlaşmasına kadar Anadolu’nun farklı bölgelerinde yaşamış olan Hıristiyan
Ortodokslar hayatlarının pek çok alanında Türkçe kullanmışlardır. Kullanmış oldukları Türkçeyi sadece komşuları ile
iletişim için değil aynı zamanda çeşitli geleneksel tören ve özel günlerde de
(dini ritüeller, evlilik törenleri, ninniler, vb.) kullanmaları Ortodokslar
arasında zengin bir Türkçe sözlü geleneğin doğmasını sağlamıştır. Zorunlu
göçleri sırasında maddi anlamda yanlarında çok fazla bir şey götürme sansı
olmayan mübadiller, kültür ve kimliklerini yeni yaşayacakları yerlere
taşımışlardır. Yeni topraklara uyum noktasında yaşadıkları sorunlar, onların
şarkı ve türkülerine de yansımıştır. Belleklerin de getirdikleri türkülerin
yanında yeni vatanlarındaki sorunlar ve eski vatanlarına duydukları hasreti
içeren yeni türküler söylemeye başlamışlardır. Ağıt şeklinde olan bu eserler
göç sorunları, özlem ve hayıflanma gibi duyguları içeriyordu. Bu bağlamda
çalışma içerisinde özel arşivlerde ve alan çalışmalarında kayıt edilmiş olan
“Mübadele Türküleri” veya “Mübadele Ağıtları”
adı verilen türküler ele alınmıştır. Yunanistan’daki mübadil köylerinde
ve özel arşivlerde karşılaşılan bu eserler, notaya alınırken, mübadelenin Yunan
tarafındaki etkilerinin sözlü kültür ve müzik kültürü üzerindeki etkilerinin
anlaşılması, bu türküler üzerinden değerlendirilmiştir.
İletişim Perspektifinden Siyasal İletişim ve Seçim Kampanyaları

Published: January 2020

Siyaset ve iletişim
bilimlerinin kesişim noktasında bulunan siyasal iletişim üzerine yapılan çalışmalar,
eleştirel ve Anglo-Amerikan olmak üzere 2 ana yaklaşım çerçevesinde
yürütülmektedir. Anglo-Amerikan yaklaşım çerçevesinde ele alınan çalışmalar
iletişimi, iletişim araçlarının kamuoyunun oluşumundaki etkilerini konu yapmış
çalışmalardır. Buna karşılık, eleştirel kuram pespektifinden siyasal iletişim,
deneysel çalışmaları içermekle birlikte saf ampirizme karşıdır ve eleştireldir.
Bu çalışmada, iletişim bilimi genelinde siyasal iletişim kavramı, unsurları ve
tarihsel arka planı betimleyici bir çerçevede işlenmektedir. Çalışma kapsamında
siyasal iletişimin kavramsal boyutunun yanısıra, siyasal iletişimin aktörleri,
seçim kampanyalarında kullanılan iletişim yöntem ve araçları Türkiye’de
özellikle 1946 – 1995 yılları arasındaki yürütülen seçim kampanları örnekleri
özelinde ele alınarak Anglo-Amerikan yaklaşımdan etkilenişi ortaya konmaya
çalışılmıştır.

Küresel iletişim perspektifinden siyasal iletişim ve seçim
kampanyalarının ABD’deki uygulamaları çerçevesinde Türkiye’deki yansımalarına
bakıldığında görülmektedir ki siyasal partilerin seçmenleriyle kurdukları
iletişim seçim dönemlerinde yoğunlaşmakta, gerek kullanılan yöntem gerek
kullanılan iletişim araçları ve gerekse gönderilen mesaj kapsamları diğer
dönemlerden daha farklı ve yoğun olmaktadır.
