A new smoothing method for solving nonlinear complementarity problems
Authors: Zhu Jianguang , Hao Binbin 
Published: March 2019

Abstract
In this paper, a new improved smoothing Newton algorithm for the nonlinear complementarity problem was proposed. This method has two-fold advantages. First, compared with the classical smoothing Newton method, our proposed method needn’t nonsingular of the smoothing approximation function; second, the method also inherits the advantage of the classical smoothing Newton method, it only needs to solve one linear system of equations at each iteration. Without the need of strict complementarity conditions and the assumption of P0 property, we get the global and local quadratic convergence properties of the proposed method. Numerical experiments show that the efficiency of the proposed method.
Collective Obligations and Demandingness Complaints
Authors: Berkey Brian 
Published: March 2019

AbstractIt has been suggested that understanding our obligations to address large-scale moral problems such as global poverty and the threat of severe climate change as fundamentally collective can allow us to insist that a great deal must be done about these problems while denying that there are very demanding obligations, applying to either individuals or collectives, to contribute to addressing them. I argue that this strategy for limiting demandingness fails because those who endorse collective obligations to address large-scale moral problems have no grounds for denying that the relevant collectives are obligated to do what is impartially best. Specifically, I argue that appeals to the claim that collective obligations to do what is impartially best would be objectionably demanding cannot succeed, for two reasons. The first is that demandingness complaints cannot be aggregated across the individual members of a collective. And the second is that demandingness complaints cannot plausibly be asserted on behalf of collectives themselves. I conclude by suggesting some reasons to think that collective obligations to address large-scale problems will tend to imply demanding individual obligations.

Studying robots outside the lab: HRI as ethnography
Authors: Blond Lasse 
Published: March 2019

Abstract
As more and more robots enter our social world, there is a strong need for further field studies of humanrobot interaction. Based on a two-year ethnographic study of the implementation of a South Korean socially assistive robot in Danish elderly care, this paper argues that empirical and ethnographic studies will enhance the understanding of the adaptation of robots in real-life settings. Furthermore, the paper emphasizes how users and the context of use matters to this adaptation, as it is shown that roboticists are unable to control how their designs are implemented and how the sociality of social robots is inscribed by its users in practice. This paper can be seen as a contribution to long-term studies of HRI. It presents the challenges of robot adaptation in practice and discusses the limitations of the present conceptual understanding of human-robot relations. The ethnographic data presented herein encourage a move away from static and linear descriptions of the implementation process toward more contextual and relational accounts of HRI.

Abstract
Here in this study timing saving, easy and cost effective methods has been applied for fabricating the dielectric energy storage materials. Ceramic nanoparticles (FLZC’s) have been successfully synthesized by Sol-Gel method and its nanocomposites with non-conducting polymers (PVP, PVA, PEG, PEO) and multiwalled carbon nanotubes (MWCNT’s) by one-pot blending technique. Energy dispersive x-ray diffraction (EDX), x-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA/DTA), AC impedance analyzer and dielectric properties were determined for all the samples. Dielectric properties showed good agreement with that of energy storage substances for electronic device fabrication. High dielectric constant was achieved when 0.5 wt% MWCNT’s was added to FLZC’s/MWCNT’s/Polymer nanocomposites. The stability and performance of the nanocomposites were dependent on the type of polymer used. These preparation materials can be employed in functional materials, such as high charge-storage capacitors, electrostriction for artificial muscles and smart skins etc.
Internet y postmodernidad: un soporte de comunicación tan necesario como irreverente en la actualidad. Necesidades pedagógicas
Authors: Rubio José Hernández 
Published: March 2019

Una herramienta de comunicación como Internet ha supuesto una revolución descomunal en nuestro mundo globalizado. Sólo en unas décadas, la “Red de redes” se ha erigido en protagonista absoluto en el ámbito de las interrelaciones virtuales. Y dicha tecnología, que facilita el acceso e intercambio de información a millones de personas, se ha fraguado en nuestro contexto sociocultural de la Postmodernidad. El resultado es una concepción infinita de perspectivas a nivel comunicativo. La realidad queda frecuentemente a merced de esas subjetividades, capaces de influir en amplios colectivos humanos según ciertos intereses. Por tanto, junto a la constatación de la eficacia y necesidad de Internet, este trabajo pretende analizar el porqué de la validez de dichas verdades múltiples, que han superado los principios objetivables de la Modernidad (según el supuesto progreso de la Razón). Al respecto, resulta fundamental examinar fenómenos como la post-verdad o el uso malintencionado de las redes sociales, que distorsionan la autenticidad de situaciones sociales y políticas de gran calado. Para ello, ha sido de gran estima extraer nociones esenciales de otras publicaciones, escritas o virtuales, que lo abordan con rigor. Igualmente, de gran utilidad es analizar determinadas informaciones en la Red, que obedecen a la irreverencia de unos intereses prefijados. La conclusión deriva en una reflexión necesaria sobre las alternativas de opinión que coinciden con el individualismo que emana la Posmodernidad, con Internet como aliado. De primer orden es la urgencia de seguir apostando por una educación a todos los niveles sobre un fenómeno ilimitado.

Published: March 2019

Abstract
Accurately obtaining the mechanics parameters of the surrounding rock at an engineering site in real time is a key component of the construction process that is required to determine and adjust the support scheme in a timely manner and thus ensure construction safety. Currently, studies of the real-time measurement methods of the cohesion, c, and internal friction angle, φ, of the surrounding rock at a site are relatively limited, and the digital core drilling test technique provides a new approach for obtaining accurate rock parameters (c and φ) in real time at an underground engineering site. Based on the principle of upper bound analysis, in this article, a relationship model between the core drilling parameters and rock mechanics parameters (CDP-RMP) is established, and the rock core drilling cutting strength is obtained. An inversion method is proposed to obtain the rock parameters (c and φ). Additionally, by using the multifunctional rock digital drilling test system developed, digital core drilling tests are conducted on rock specimens with different lithologies. The results show that the inversion values for the rock parameters c and φ are essentially consistent with the results of the triaxial test, which verifies the accuracy of the CDP-RMP model and that of the inversion method for the rock parameters c and φ. A real-time method for obtaining rock mechanics parameters based on the digital core drilling test is further established. This method can conveniently obtain accurate mechanical parameters for the surrounding rock onsite in real time and provides a foundation for the timely optimization of the support scheme and the informatization construction of underground engineering.
Evaluation and Modeling of the Effect of Tool Edge Radius on Machined Surface Roughness in Turning UNS A92024-T351 Aluminum Alloy
Authors: Fang Ning , Srinivasa Pai P. 
Published: March 2019

Abstract
Tool edge radius plays a significant role in affecting the surface integrity of machined products. The vast majority of existing research, however, takes no account of the effect of tool edge radius in the evaluation and modeling of machined surface roughness, an essential indicator of surface integrity. The present study fills this important research gap and has performed a total of 45 turning experiments on Unified Numbering System (UNS) A92024-T351 aluminum alloy with carefully selected cutting tools with three levels of tool edge radii. This article describes the experimental setup and measurements of tool edge radius and machined surface roughness. Machined surface roughness was evaluated using five parameters, including average roughness, root-mean-square roughness, peak roughness, maximum roughness height, and five-point average roughness. The experimental evidence presented in this article shows that the tool edge radius has a profound effect on machined surface roughness, cutting forces, and cutting vibrations. Based on the experimental data, three types of predictive models are developed, including a multiple regression model, multilayer perceptron neural network model, and radial basis function neural network model. The prediction accuracy of the three models is compared based on average mean squared errors. The results show that different models lead to different prediction accuracy for different surface roughness parameters.
Synaptopodin Deficiency Ameliorates Symptoms in the 3xTg Mouse Model of Alzheimer's Disease

Published: March 2019

Disruption in calcium homeostasis is linked to several pathologies and is suggested to play a pivotal role in the cascade of events leading to Alzheimer's disease (AD). Synaptopodin (SP) residing in dendritic spines has been associated with ryanodine receptor (RyR), such that spines lacking SP release less calcium from stores. In this work, we mated SPKO with 3xTg mice (3xTg/SPKO) to test the effect of SP deficiency in the AD mouse. We found that 6-month-old male 3xTg/SPKO mice restored normal spatial learning in the Barns maze, LTP in hippocampal slices, and expression levels of RyR in the hippocampus that were altered in the 3xTg mice. In addition, there was a marked reduction in 3xTg-associated phosphorylated tau, amyloid β plaques, and activated microglia in 3xTg/SPKO male and female mice. These experiments indicate that a reduction in the expression of SP ameliorates AD-associated phenotype in 3xTg mice.SIGNIFICANCE STATEMENTThis study strengthens the proposed role of calcium stores in the development of AD-associated phenotype in the 3xTg mouse model, in that a genetic reduction of the functioning of ryanodine receptors using synaptopodin-knock-out mice ameliorates AD symptoms at the behavioral, electrophysiological, and morphological levels of analysis.
Centrosome Loss Triggers a Transcriptional Program To Counter Apoptosis-Induced Oxidative Stress

Published: March 2019

Abstract
Centrosomes are important mediators of mitotic spindle assembly, and loss of centrosomes can lead to mitotic errors and cell death; however, it is also clear that cells can compensate for centrosome loss through multiple mechanisms...
Centrosomes play a critical role in mitotic spindle assembly through their role in microtubule nucleation and bipolar spindle assembly. Loss of centrosomes can impair the ability of some cells to properly conduct mitotic division, leading to chromosomal instability, cell stress, and aneuploidy. Multiple aspects of the cellular response to mitotic error associated with centrosome loss appear to involve activation of JNK signaling. To further characterize the transcriptional effects of centrosome loss, we compared gene expression profiles of wild-type and acentrosomal cells from Drosophila wing imaginal discs. We found elevation of expression of JNK target genes, which we verified at the protein level. Consistent with this, the upregulated gene set showed significant enrichment for the AP-1 consensus DNA-binding sequence. We also found significant elevation in expression of genes regulating redox balance. Based on those findings, we examined oxidative stress after centrosome loss, revealing that acentrosomal wing cells have significant increases in reactive oxygen species (ROS). We then performed a candidate genetic screen and found that one of the genes upregulated in acentrosomal cells, glucose-6-phosphate dehydrogenase, plays an important role in buffering acentrosomal cells against increased ROS and helps protect those cells from cell death. Our data and other recent studies have revealed a complex network of signaling pathways, transcriptional programs, and cellular processes that epithelial cells use to respond to stressors, like mitotic errors, to help limit cell damage and maintain normal tissue development.
Consideraciones en torno a la Corte Penal Internacional
Authors: Garc Ruth Cristina 
Published: March 2019

ResumenLa creación de la Corte Penal Internacional -cuyo Estatuto fue aprobado el 17 de julio de 1998-, como Tribunal permanente de justicia penal internacional, es de los sucesos mas trascendentales del siglo XX. Tal creación debe ser vista como la culminación de un proceso formalmente iniciado alrededor de medio siglo antes. Con la Resolución de las Naciones Unidas de diciembre de 1946 -fresca at'.n en la memoria la catastrofe que significó la Segunda Guerra Mundial-, mediante la cual este organismo internacional condenó el delito de genocidio como un crimen contra el Derecho Internacional. El propósito de contar con un Tribunal internacional permanente que juzgue los delitos que atenten contra la paz y seguridad, no ha estado libre de obstáculos. Los antecedentes de los tribunales internacionales penales que hasta hoy han existido, no coinciden, ni mucho menos, con la expedición de la Resolución de las Nacio- nes Unidas que se ha referido -objetivo alcanzado el 1 de julio de 2002, con la entrada en vigor del Estatuto de la CPI, al completarse las sesenta ratificaciones necesarias–, sino que son anteriores a la Segunda Guerra Mundial. AbstractThe creation of the International Criminal Court -which Statute was ap- proved on July 17, 1998- as a permanent international criminal court of jus- tice, is one of the most important events of the XX century. This event should be seen as the culmination of a process which formally started about half a century before. Indeed, it was through the Resolution adopted by the UN on December 1946 -still fresh in people's memory due to the catastrophe that WWII meant- by which this international organization condemned genocide as a crime against International Law. The purpose of having a permanent in- ternational Tribunal to judge the crimes that threaten the peace and security of humanity has not been pursued without obstacles. The previous attempts to create international criminal tribunals do not match what was established in the Resolution of the UN aforementioned -its purpose seems to have been reached on July 1, 2002, with the entry into force of the Statute of the Inter- national Criminal Court, on completion of the sixty ratifications needed- but that predate WWII.
Soberanía, globalización y la constitucion de significado

ResumenEn este articulo se demostrara cómo la perdida de soberania del Derecho y de la nación ha implicado la emergencia de nuevos lugares de construcción de la identidad y como estas nuevas identidades han llegado a ser globales, debido a la perdida de centralidad del Estado-Nación como lugar de producción de significado. Mediante el analisis del concepto de soberania y de su relación con el poder de nombrar qué posee el Estado, ejercido a través de la ley, se mostrara cómo en una sociedad del espectaculo este poder es quitado al Estado y dado a otros lugares que puedan garantizar la pasividad de los espectadores y por tanto la ausencia de resistencia en la construcción del significado. Esto mediante el análisis de una telenovela colombiana y su manejo del concepto de corrupción para mostrar cómo el significado legal fue superado por aquel construido en los medios de comunicación. AbstractIn this essay I wish to show how law's and the nation's loss of sovereignty have meant the emergence of new sites of identity construction and how these new identities have become global due to the loss of centrality of the Nation- State as place of meaning production. By analyzing the concept of sovereignty and its relation to the power of naming held by the State, and exercised through the law, I want to show how in a society of the spectacle that power is removed from the State and given to other places that can ensure passivity of viewers and thus the absence of resistance in the construction of meaning. This I will do by analyzing a Colombian soap opera and its handling of the concept of corruption to show legal meaning was overtaken by the one built in the media

Correction of Adolescent Idiopathic Scoliosis Using a Convex Pedicle Screw Technique
Authors: Tsirikos Athanasios I. 
Published: March 2019

Background:
We describe our convex segmental pedicle screw technique for the treatment of adolescent idiopathic scoliosis. We developed this technique to achieve optimum 3-dimensional deformity correction while reducing the surgical risks of an inherently dangerous procedure.

Description:
The surgery involves a wide posterior subperiosteal exposure across the deformity levels to the tips of the transverse processes. Posterior releases are performed through facetectomies. Pedicle screws are placed using a freehand technique based on anatomical landmarks. Adequate screw positioning is assessed with an image intensifier before rod engagement. Segmental pedicle screws are placed across the convexity of each curve included in the fusion. Proximal and distal fixation of the rods on the contralateral side is performed across 2 pedicle screw anchors. We use titanium rods bilaterally. Curve correction is done using the convex pedicle screws by applying segmental vertebral translation and derotation starting with the main thoracic curve followed by the lumbar curve. Segmental compression or distraction is performed at the proximal and distal ends of the construct to level the end vertebrae included in the fusion. Maximum correction of the main thoracic scoliosis is done, whereas the lumbar scoliosis (which is usually more flexible) is corrected to the point that results in a globally balanced spine in the coronal plane. The rod attached on the convex side of the main thoracic scoliosis is overbent to restore thoracic kyphosis, and the aim is always to achieve regional and global sagittal balance. An interfacetal, intertransverse, and interlaminar fusion is performed with use of locally harvested bone supplemented by allograft bone.

Alternatives:
With previous techniques, the use of bilateral segmental pedicle screw fixation has been advocated as a requirement to achieve adequate deformity correction in patients with adolescent idiopathic scoliosis.

Rationale:
This technique is associated with low risks of neurological and vascular complications because the screws are placed at the convex pedicles, away from the spinal cord/cauda equina and the aorta. The use of far fewer pedicle screws compared with previous techniques reduces surgical time and blood loss, which is related to lower postoperative morbidity. It may also decrease the risk of deep wound infection, which is associated with the number of implants used. Low implant density (1.2, with a density of 2 representing placement of pedicle screws bilaterally at every instrumented segment) with our technique can achieve satisfactory scoliosis correction, improved thoracic kyphosis, and normal global sagittal balance. Our use of this technique has resulted in excellent patient satisfaction and functional outcomes with no neurological complications or intraoperative neuromonitoring events, deep wound infections, detected nonunions, or need for revision surgery.
