Maxfischeriinae: a new braconid subfamily (Hymenoptera) with highly specialized egg morphology

The tribe Maxfischeriini, previously placed in Helconinae, is emended to subfamily status based on morphological and biological evidence. Proposed autapomorphies for Maxfischeriinae include: the presence of a pronotal shelf, forewing vein 1a and 2a present, although 1a nebulous, ventral valve of the ovipositor with serrations from tip to base and specialized egg morphology. The novel, pedunculate egg morphology is described for Maxfischeria, representing a new life‐history strategy among Braconidae. Based on egg and ovipositor morphology, we suggest that Maxfischeria is a proovigenic, koinobiont ectoparasitoid. Five new species of Maxfischeria Papp are described with an illustrated key to all species (Maxfischeria ameliaesp.n., Maxfischeria anicsp.n., Maxfischeria briggsisp.n., Maxfischeria folkertsorumsp.n. and Maxfischeria ovumancorasp.n.). In addition to the identification key presented here, all known species of Maxfischeria can be separated using the barcoding region of cytochrome c oxidase subunit I (COI). Based on molecular data, the phylogenetic relationships among the six known species of Maxfischeria are as follows: (M. folkertsorumsp.n. (M. ovumancorasp.n. (M. briggsisp.n. (M. anicsp.n. (M. tricolor + M. ameliaesp.n.))))).
Redescription of Nematodes Pharyngodon mamillatus and Thelandros sp. from Some Reptiles of Qena, Egypt

During the present study, about 294 Mabuya quinquetaeniata (the common name is bean skin, sehlia garraiya), 196 0f Ptyodactylus hasselquistti (the common name is fan footed gecko, bors abukaff,) 60 Tarentola annularis (the common name is Egyptian gecko, white spotted gecko), 30 0f Hemidactylus turicicus (the common name is Turkish gecko, bors manzeli), 106 of Chalcides ocellatus (the common name is eyed shink, Sehlia doffana) and 30 of Chalcides sepsoides (the common name is Audouin's sand; Sehlia nana) were collected from different localities of Qena Governorate which considered as a new locality for this. Two nematode species were found and identified. The first species is Pharyngodon mamillatus which belonging to family Pharyngodonidae Travassos, 1919 and collected from the large intestine of Mabuya quinquetaeniate (38 out 294), Ptyodatctylus hasselquistti (112 out 196), Tarentola annularis (40 out of 60), and Hemidactylus turicicus (120 out of 130), the rate of infections were 12.9%, 57.1%, 80%, 92.3% respectively. The second species is Thelandros sp. which was collected from the large intestine of Chalcides ocellatus, (54 out of 106), Chalcides sepsoides (20 out of 30), Ptyodactus hasselquistti (6 out of 196) and Hemidactylus turicicus (4 out of 130), the rate of infections were 50.9%, 66.6%, 3.06% and 3.07%, respectively.
Cross-Site Cold-Start Product Recommendation for Social Media and E-Commerce Websites

: In recent years the gap between social media and e-commerce reduced tremendously. Many e-commerce websites used social login in status or information for their users’ login verification and allow new users to sign in with their existing social login log in information. Both Facebook and Twitter have introduced a new feature last year that allow users to buy products directly from their websites by clicking a “buy” button to purchase items in adverts or other posts. With the new trend of conducting e-commerce activities on social networking sites, it is important to leverage knowledge extracted from social networking sites for the development of product recommender systems. This paper presents a system for predicting user’s purchase behaviors on e-commerce websites from the user’s social media profile.
Weakly-Supervised Deep Convolutional Neural Network Learning for Facial Action Unit Intensity Estimation

Facial action unit (AU) intensity estimation plays an important role in affective computing and human-computer interaction. Recent works have introduced deep neural networks for AU intensity estimation, but they require a large amount of intensity annotations. AU annotation needs strong domain expertise and it is expensive to construct a large database to learn deep models. We propose a novel knowledge-based semi-supervised deep convolutional neural network for AU intensity estimation with extremely limited AU annotations. Only the intensity annotations of peak and valley frames in training sequences are needed. To provide additional supervision for model learning, we exploit naturally existing constraints on AUs, including relative appearance similarity, temporal intensity ordering, facial symmetry, and contrastive appearance difference. Experimental evaluations are performed on two public benchmark databases. With around 2% of intensity annotations in FERA 2015 and around 1% in DISFA for training, our method can achieve comparable or even better performance than the state-of-the-art methods which use 100% of intensity annotations in the training set.
Constructing coincident and leading indices of economic activity for the Brazilian economy

This paper has three original contributions. The first is the reconstruction effort of the series of employment and income to allow the creation of a new coincident index for the Brazilian economic activity. The second is the construction of a coincident index of the economic activity for Brazil, and from it, (re)establish a chronology of recessions in the recent past of the Brazilian economy. The coincident index follows the methodology proposed by TCB and it covers the period 1980:1 to 2007:11. The third is the construction and evaluation of many leading indicators of economic activity for Brazil which fills an important gap in the Brazilian Business Cycles literature.
Toxicity potential of heartwood extractives from two mulberry species against Heterotermes indicola

Choice and no-choice tests were run to evaluate natural resistance of the woods of two Morus species (Morus alba and Morus nigra) against the subterranean, Heterotermes indicola, under field conditions. Toxicity, antifeedant and repellency potential of the heartwood extractives was also investigated under laboratory conditions. Heartwood extractives were removed from wood shavings by using methanol or an ethanol: toluene (2:1) mixture. Results of choice and no-choice tests with sap and heartwood blocks exposed to termites, showed that both mulberry species were resistant to termites but in comparison, Morus alba wood was more resistant than Morus nigra to termite feeding as it showed <5 % weight loss after 90 days. Termites exhibited a concentration dependent mortality after exposure to either mulberry species’ heartwood extractives. The highest termite mortality occurred after termites were exposed to filter paper treated with Morus alba extractives at a concentration of 5 %. At this concentration, antifeedancy and repellency were calculated to be 91,67 and 84 % respectively. Our results also showed that extractives from either mulberry species imparted resistance to vacuum-pressure treated non-durable Populus deltoides wood. Termite mortality was greater than 75 % after feeding on Populus deltoides wood treated with extractives from Morus alba. Solvent only (methanol) treated Populus deltoides controls, showed a minimum weight loss of 2,69 % after 28 days. These results suggest that Morus alba extractives have antitermitic properties and may be potentially useful in the development of environment friendly termiticides.
Topic : Advances in Minimally Invasive Cirrhotic Surgery

Liver resection has dramatically evolved over the last four decades. Initial series incurred high morbidity and mortality rates. [1,2] However, with the introduction of modern anesthesia and improved knowledge of the surgical anatomical segments the mortality decreased to acceptable levels lending to the proliferation of resection programs. [3-5] In the last decade we have witnessed a second proliferation of hepatic resections attributed to the introduction of the laparoscopic technique. [6,7] However, the greatest challenge in the resection of hepatic tumors remains their management in the setting of cirrhotic liver. [8,9]
RECENT ADVANCES IN THE PREPARATION OF OIL PALM WASTE-BASED ADSORBENTS FOR REMOVAL OF ENVIRONMENTAL POLLUTANTS-A

The palm oil industry is an excellent source for huge quantities of highly useful biomass. Utilization of oil palm biomass-based materials for the removal of environmental pollutants appears to be a viable solution in the lights of promoting sustainable development. This article aims to review recent advances in the preparation of adsorbent from different parts of oil palm biomass for the removal of heavy metal and organic environmental pollutants from water. Physical and chemical factors that enhance the applicability of oil palm waste as adsorbents are also discussed. It is clear that each part of the oil palm biomass is potentially applicable as biosorbents for most environmental pollutants and the capability could be further enhanced through modifications in accordance with its intended pollutants. Modifications by chemical treatments such as acidic, basic or drying agent treatments under optimum dosages have been found to have significant effects on the selectivity of the analyte absorption. In general, basic treatment is more suitable for common pollutants such as metals, pesticide and basic dyes. Meanwhile, the acidic treatment is more suitable for non-polar organic pollutants such as phenols. Recent trends in the application of oil palm biomass as biosorbents are also discussed that together open new doors to sustainable development.
4D Printing Dielectric Elastomer Actuator Based Soft Robots

4D printing is an emerging technology that prints 3D structural smart materials that can respond to external stimuli and change shape over time. 4D printing represents a major manufacturing paradigm shift from single-function static structures to dynamic structures with highly integrated functionalities. Direct printing of dynamic structures can provide great benefits (e.g., design freedom, low material cost) to a wide variety of applications, such as sensors and actuators, and robotics. Soft robotics is a new direction of robotics in which hard and rigid components are replaced by soft and flexible materials to mimic mechanisms that works in living creatures, which are crucial for dealing with uncertain and dynamic tasks. However, little research on direct printing of soft robotics has been reported. Due to the short history of 4D printing, only a few smart materials have been successfully 4D printed, such as shape memory and thermo-responsive polymers, which have relatively small actuation strains (up to ~8%). In order to produce the large motion, dielectric elastomer actuator (DEA), a sheet of elastomer sandwiched between two compliant electrodes and known as artificial muscle for its high elastic energy density and capability of producing large strains (~200%), is chosen as the actuator for soft robotics. Little research on 3D printing silicone DEA soft robotics has been done in the literature. Thus, this thesis is motivated by applying the advantages in 3D printing fabrication methods to develop DEA soft robotics. The ultimate research goal is to demonstrate fully printed DEA soft robots with large actuation. In Chapter 1, the research background of soft robotics and DEAs are introduced, as well as 3D printing technologies. Chapter 2 reports the rules of selecting potentially good silicone candidates and the printing process with printed material characterizations. Chapter 3 studies the effects of pre-strain condition on silicone material properties and the performance of DEA configurations, in order to obtain large actuation strain. In Chapter 4, two facial soft robots are designed to achieve facial expressions as judged by a smiling lip and expanding pupils based on DEA actuation. Conclusions and future developments are given in chapter 5. ACKNOWLEDGEMENTS I would like to express my deepest appreciation to my thesis advisor, Prof. WenChao Zhou, for his support and guidance throughout my thesis research. It is a great opportunity to participate in the 4D printing project in Dr. Zhou’s group. The experience gained during this project is very helpful for my future development. Besides my advisor, I would like to thank the rest of my thesis committee, Prof. Steve Tung and Prof. Adam Huang for their encouragement, insightful comments, and important advising about the independent thinking skill. At last, I would like to deeply thank my family, especially my parents, for their support and encouragement.
Forecasting the evolution of seismicity in southern California : Animations built on earthquake stress transfer : Stress transfer, earthquake triggering, and time-dependent seismic hazard

[1] We develop a forecast model to reproduce the distribution of main shocks, aftershocks and surrounding seismicity observed during 1986-2003 in a 300 x 310 km area centered on the 1992 M = 7.3 Landers earthquake. To parse the catalog into frames with equal numbers of aftershocks, we animate seismicity in log time increments that lengthen after each main shock; this reveals aftershock zone migration, expansion, and densification. We implement a rate/state algorithm that incorporates the static stress transferred by each M > 6 shock and then evolves. Coulomb stress changes amplify the background seismicity, so small stress changes produce large changes in seismicity rate in areas of high background seismicity. Similarly, seismicity rate declines in the stress shadows are evident only in areas with previously high seismicity rates. Thus a key constituent of the model is the background seismicity rate, which we smooth from 1981 to 1986 seismicity. The mean correlation coefficient between observed and predicted M > 1.4 shocks (the minimum magnitude of completeness) is 0.52 for 1986-2003 and 0.63 for 1992-2003; a control standard aftershock model yields 0.54 and 0.52 for the same periods. Four M > 6.0 shocks struck during the test period; three are located at sites where the expected seismicity rate falls above the 92 percentile, and one is located above the 75 percentile. The model thus reproduces much, but certainly not all, of the observed spatial and temporal seismicity, from which we infer that the decaying effect of stress transferred by successive main shocks influences seismicity for decades. Finally, we offer a M > 5 earthquake forecast for 2005-2015, assigning probabilities to 324 10 x 10 km cells.
Acute hypotensive and diuretic activities of Berberis vulgaris root bark aqueous extract in normal rats

The aim of this study is to investigate the effectiveness of intravenous administration of Berberis vulgaris root bark aqueous extract (BRBD) on the cardiovascular and renal functions of healthy normotensive rats. The different doses of BRBD 1, 10 and 20 mg/kg were administered intravenously (i.v) in normal rats. Blood pressure, diuretic activity and serum renal profile were analyzed. Intravenous injection of BRBD at the different doses of 1, 10 and 20 mg/kg showed a dose-dependent reduction in mean arterial blood pressure (P<0.001). At different doses of 1, 10 and 20 mg/kg, the hypotensive effect remained for more than one hour. Single dose administration of BRBD at doses of 10 and 20 mg/kg caused a significant increase in urine output (P<0.001) as compared to the control rats. Serum renal profile test (albumin, Urea, Uric Acid, creatinine and BUN) did not show any significant alteration. The authors conclude that the BRBD is a potent hypotensive and possesses diuretic potential
Coevolución genética Homo sapiens-Helicobacter pylori y sus implicaciones en el desarrollo del cáncer gástrico: una revisión sistemática

Helicobacter pylori (H. pylori), clasificada como carcinogeno tipo I para cancer gastrico (CG), ha acompanado al hombre al menos desde hace 116 000 anos. Los conocimientos de las fuerzas evolutivas que modulan el rol de esta bacteria en el desarrollo del espectro de enfermedades gastricas son aun escasos. Esta revision sistematica recopila articulos que reportan un proceso de coevolucion, relacionan los componentes ances- trales huesped-hospedero y describen mecanismos adaptativos de H. pylori al entorno gastrico humano, con el fin de comprender si el proceso de coevolucion modula la patogenicidad de la bacteria y el desarrollo de enfermedades gastricas. Se realizo una busqueda sistematica en las bases de datos electronicas: MEDLINE (OvidSP), Scopus (ScienceDirect), Scielo y Tree of Science (ToS); terminos de busqueda: “stomach”, “can- cer”, “neoplasms”, “ethinicity”, “evolution”, “genetics”, “ancestry” y “Helicobacter pylori”. Idiomas: ingles y es- panol. Los datos fueron filtrados por un revisor utilizando un formulario estandar de extraccion y ulteriormente revisados por otro. El riesgo de sesgo y la calidad metodologica de los estudios fueron evaluadas con el programa: Critical Appraisal Skills Programme (CASP). Del total de 1584 estudios, 36 cumplieron los criterios de inclusion. Los factores mas relevantes en el desarrollo del espectro de enfermedades asociadas con la infeccion por H. pylori son: la disrupcion en el proceso de coevolucion entre la bacteria y su huesped humano –por la transferencia horizontal de segmentos de genes que no han evolucionado con sus anfitriones–; las sustituciones de aminoacidos; la fijacion y la seleccion positiva principalmente en las regiones hipervariables.

De un total de 41 alumnos encuestados de tercer año el 88% (36 alumnos) tienen un alto grado de motivación extrínseca por el aprendizaje, y de un total de 27 alumnos de quinto año el 67% (18 alumnos) tienen alto grado de motivación extrínseca por el aprendizaje. Conclusiones: los estudiantes de Enfermería de la UNMSM tienen alto grado de motivación por el aprendizaje tanto en la dimensión extrínseca como intrínseca pero con una disminución significativa en los estudiantes del 5to año de estudios en comparación a los de 3ero, asumiendo a priori, que puede deberse a la diferencia de roles académicos.
Generalized black-box large deviation simulations: High-precision work distributions for extreme non-equilibrium processes in large systems

The distributions of work for strongly non-equilibrium processes are studied using a very general form of a large-deviation approach, which allows one to study distributions of almost arbitrary quantities of interest for equilibrium, non-equilibrium stationary and even non-stationary processes. The method is applied to varying quickly the external field in a wide range B=3 0 for critical (T=2.269) two-dimensional Ising system of size LxL=128x128. To obtain free energy differences from the work distributions, they must be studied in ranges where the probabilities are as small as 10^{-240}, which is not possible using direct simulation approaches. By comparison with the exact free energies, which are available for this model for the zero-field case, one sees that the present approach allows one to obtain the free energy with a very high relative precision of 10^{-4}. This works well also for non-zero field, i.e., for a case where standard umbrella-sampling methods seem to be not so efficient to calculate free energies. Furthermore, for the present case it is verified that the resulting distributions of work for forward and backward process fulfill Crooks theorem with high precision. Finally, the free energy for the Ising magnet as a function of the field strength is obtained.
Tropical tree diversity enhances light capture through crown plasticity and spatial and temporal niche differences

Light partitioning is often invoked as a mechanism for positive plant diversity effects on ecosystem functioning. Yet evidence for an improved distribution of foliage in space or time in diverse plant communities remains scarce, and restricted mostly to temperate grasslands. Here we identify the mechanisms through which tree species diversity affects community-level light capture in a biodiversity experiment with tropical trees that displays overyielding, i.e., enhanced biomass production in mixtures. Using a combination of empirical data, mechanistic models, and statistical tools, we develop innovative methods to test for the isolated and combined effects of architectural and temporal niche differences among species as well as plastic changes in crown shape within species. We show that all three mechanisms enhanced light capture in mixtures and that temporal niche differences were the most important driver of this result in our seasonal tropical system. Our study mechanistically demonstrates that niche differences and phenotypic plasticity can generate significant biodiversity effects on ecosystem functioning in tropical forests.
Association between Thrombophilic Gene Polymor-phisms and Recurrent Pregnancy Loss in Iranian Women

Background: Recurrent pregnancy loss (RPL) is a common problem among couples, and acquired thrombophilia is the well-known etiology of RPL. The aim of this study was to establish the association between inherited thrombophilic gene polymorphisms and RPL. Methods: This case-control study was conducted on 50 women with unexplained RPL and 50 parous women with no history of miscarriage (age range: 17ג��48 years). The data were collected during 2013ג��2015 in Sarem Hospital, Tehran, Iran. Genotyping was performed using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for glycoprotein IIIa (PLA1/PLA2), KDR (Q472H), and \xCE²-fibrinogen (-455G/A); tetra-primer amplification refractory mutation system (ARMS)-PCR for glycoprotein Ia (807c/t) and vascular endothelial growth factor (VEGF) (2578c/a), and ins/del PCR for angiotensin I-converting enzyme (ACE) (intron 16 I/D). The association between the frequency of the genotypes and RPL was determined by Chi-square and Fisherג��s exact tests. Results: The results of the present study revealed a significant relationship between glycoprotein Ia (807C/T), VEGF (2578C/A), and ACE (intron 16 I/D) polymorphisms and RPL (P=0.00, 0.02, and 0.00, respectively). In contrast, no relationship was observed between \xCE²-fibrinogen (-455G/A), KDR (Q472H), and glycoprotein IIIa (PLA1/PLA2) polymorphisms and increased risk of RPL (P>0.05). Conclusion: This study demonstrated that glycoprotein Ia (807C/T), VEGF (2578C/A), and ACE (intron 16 I/D) polymorphisms may be a risk factor for the women with a history of RPL. \xC2
