Stormfront: the super-nazi, the Aryan demigod, the worst of the Third Reich's racial dreams come true... versus what's left of The Boys. Can our ragged little band defeat this dreadful ubermensch? Will the Female ever awaken from her coma? Will the cavalry arrive in time, or ever? All this and more, in the bone-snapping, gut-rupturing conclusion to The Self Preservation Society.

Characterizing the Relationship Between Degree Distributions and Community Structures

Por: Pablo Andrés; Finke Moriano Salazar | Fecha: 2014

Extended power laws and inhomogeneous connections are structural patterns often found in empirical networks. Mechanisms based on the formation of triads are able to explain the power law behavior of the degree distribution of such networks. The proposed model introduces a two-step mechanism of attachment and triad formation that illustrates how preferential linkage plays an important role in shaping the inhomogeneity of connections and the division of the network into groups of nodes (i.e., the growth of community structures). In particular, we identify conditions under which the scaling exponent of the power law correlates to a widely-used modularity measure of non-overlapping communities. Our analytical results characterize the asymptotic behavior of both the scaling exponent and the modularity, as a function of the strength with which nodes with similar characteristics tend to link to each other.

A return visit to Doctor Peculiar's yields more damning evidence against Jack from Jupiter- but even with a major supe in his sights, Butcher seems less and less happy with where the Boys' latest investigation is leading them. Hughie goes peeping where he really shouldn't, and learns more about Queen Maeve than he ever wanted to know. And before they know it, our heroes find themselves face to face with their deadliest enemies of all. Things go nuclear fast, in part three of The Big Ride.

A new exhibit has opened in Century City; a look back at the mysterious figures from the city's crime-ridden past, the original Green Hornet and Kato. The heirs of the Green Hornet legacy have decided to take in the displays, remembering what it was like to grow up with legendary fathers. But, as Britt Reid, Jr. and Mulan Kato stroll through the relics of their fathers' past, their peaceful day ends with a bang. A villain from the past wants something back from the display cases. Now, the new Green Hornet and Kato must fight their fathers' battles all over again. Lucky for Britt and Mulan, some of their fathers' weapons are right at hand.

Surgery Versus Endoscopic Therapies For Early Cancer And High-Grade Dysplasia In The Esophagus: A Systematic Review

Por: Fabio Alberto; Hourneaux de Moura Castillo Bustamante | Fecha: 2016

Background: Esophageal cancer occurs as a local disease in 22% of cases, and a minority of this disease is limited to the mucosa or submucosa (early lesions). Endoscopic mucosal resection, endoscopic submucosal dissection, photodynamic therapy, laser therapy, and argon plasma coagulation have emerged as alternatives to surgical resection for early lesions. Objective: The aim of this systematic review is to identify studies that statistically compare survival, disease-free survival, morbidity and mortality associated with the procedure, and mortality associated with cancer in the endoscopic versus surgical therapies. Results: The survival rates after 3 and 5 years were different and exhibited superiority with the surgical therapies over time. Endoscopy is superior in the control of mortality related to cancer with a high rate of disease recurrence. With regard to the comorbidity and the mortality associated with the procedure, endoscopy is superior. Conclusion: There is no evidence from clinical trials. In this systematic review, surgical therapies showed superiority for survival, and endoscopic therapies showed superiority in the control of mortality related to cancer with a high rate of disease recurrence; also, for the comorbidity and the mortality associated with the procedure, endoscopy is superior. Prospective, controlled trials with large sample sizes are necessary to confirm the results of the current analysis.
