We characterize two-dimensional Golod complexes combinatorially by vertex-breakability and topologically the fat-wedge filtration of a polyhedral product. Applying characterization, we consider difference between Golodness over fields rings, which enables us to give simple complex any field such that corresponding moment-angle is not suspension.

BACKGROUND The scientific evidence behind the mechanical function of foot orthoses is still controversial. Research studies that have investigated the kinematic effect of foot orthoses on the lower extremity have shown variable results, with orthoses causing either no significant change or a small significant change in foot kinematics. METHODS The right limbs of 12 healthy asymptomatic indivi...

PURPOSE To evaluate the correlation of kyphosis and wedge angles with pain relief and functional outcome after percutaneous vertebroplasty (PV). METHODS 15 men and 19 women aged 41 to 85 (mean, 62) years who presented with osteoporotic wedge compression fractures of the dorsolumbar spine below T5 and had failed conservative treatment were included. Patients were assessed before and one year a...

We assess the common practice of trying to learn about the sources of aggregate fluctuations using aggregate data and a representative agent framework. We take an offthe-shelf model with financial frictions and heterogeneity, and study the mapping from a credit crunch, modeled as a shock to collateral constraints, to simple aggregate wedges. We study three variants of this model that only diffe...

We propose a metamaterial approach to route terahertz waves that features subwavelength confinement in the transverse plane. The guiding mechanism is based on geometrically induced electromagnetic modes sustained by corrugated metallic wedges, whose characteristics resemble those of wedge plasmon polaritons at telecom and optical frequencies. Additionally, frequency selective focusing and slowi...

In our earlier work, we introduced a definition for the electric charge "fractional-order" multipoles using the concept of fractional derivatives and integrals [l]. Here, we utilize that definition to introduce a detailed image theory for the two-dimensional (2-D) electrostatic potential distributions in front of a perfectly conducting wedge with arbitrary wedge angles, and for the three-dimens...

X. D. Shu, J. Wei, C. Liu: College of Mechanical Engineering and Mechanics, Ningbo University, China The paper presents a new method of one closed cross wedge rolling (CWR) based wedge block to achieve near net forming of CWR shafts. The modeling is performed by using the Finite Element Method (FEM) software DEFORM-3D. The metal flow rule of the shaft is clarified by analyzing the strain and di...

By virtue of Green's Theorem, it is shown that for the diffraction of anarbitrary two-dimensional incident pulse by a wedge of angle n, the ratio of the resultantvelocity potential to the corresponding value of the incident pulse at the corner ofthe wedge at any instant is equal to 2x/ (2x — n); and that for the diffraction of a three-dimensional pulse by a cone of solid angle u...
