Encantar uma cobra de papel: Vai ser mais fácil do que possas imaginar.

, 2014
Guia de experimento que permite demonstrar como fazer com que uma cobra de papel “dance”. Para isso, é necessário: papel tipo cartolina, barbante, tesoura, lápis e lâmpada. O primeiro passo é desenhar na cartolina uma cobra enrolada e recortá-la.

Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

Related-Key Attacks on the Full-Round Cobra-F64a and Cobra-F64b [PDF]

, 2006
Cobra-F64a and Cobra-F64b, designed for firmware-oriented applications, are 64-bit Data-dependent Permutation based block ciphers with 128 key bits, which consist of 16 and 20 rounds, respectively. In this paper, we investigate their security against related-key attacks.

Effect of surface treatments on the bond strength between additively manufactured or injection‐molded high‐performance polymers and titanium

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of surface treatment and fabrication techniques of high‐performance polymers on their shear bond strength (SBS) to grade IV titanium. Materials and Methods A total of 120 pre‐milled titanium abutments were sectioned.

Pressed lithium disilicate glass ceramics: Microstructural characterization, in vitro and in silico nonlinear dynamic analysis for biaxial flexural strength

Journal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the mechanical properties of lithium disilicates, and to assess the predictive capability of in silico models for biaxial flexural strength (BFS). Materials and Methods Specimens of four heat‐pressed lithium disilicates (IPS e.max Press, Rosetta SP, LiSi Press, Vintage Prime Press) were obtained.

Influence of occlusal thickness and aging on the fracture load of additively manufactured definitive crowns in different resins

Journal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to assess the effects of occlusal thickness and thermomechanical aging on the fracture load of additively manufactured (AM) definitive crowns made from resins with different compositions, compared with crowns subtractively manufactured (SM) from a polymer‐infiltrated ceramic network. Materials and

Human Monoclonal scFvs that Neutralize Fribrinogenolytic Activity of Kaouthiagin, a Zinc-Metalloproteinase in Cobra (Naja kaouthia) Venom

Toxins, 2018
Snake venom-metalloproteinases (SVMPs) are the primary factors that disturb hemostasis and cause hemorrhage in the venomous snake bitten subjects. Kaouthiagin is a unique SVMP that binds and cleaves von Willebrand factor (vWF) at a specific peptide bond ...

COBRA: A combined regression strategy

Journal of Multivariate Analysis, 2016
A new method for combining several initial estimators of the regression function is introduced. Instead of building a linear or convex optimized combination over a collection of basic estimators $r_1,\dots,r_M$, we use them as a collective indicator of the proximity between the training data and a test observation. This local distance approach is model-
