Screw-Together Cube
نویسنده
چکیده
My G4G8 exchange item is a screw-together cube made of two identically shaped nylon parts, one dyed red and one dyed yellow. It can be seen as a cube sliced by the propeller of an airplane flying through it. Formally, it is cube which has been split along a helicoid surface whose axis is aligned with a two-fold axis of the cube, i.e. passing from one edge midpoint to the opposite edge midpoint. The helicoid makes exactly one revolution between these edges. The form can also be understood as a mating nut and bolt, designed to be the same shape.

Improved Conditional Cube Attacks on Keccak Keyed Modes with MILP Method
Conditional cube attack is an efficient key-recovery attack on Keccak keyed modes proposed by Huang et al. at EUROCRYPT 2017. By assigning bit conditions, the diffusion of a conditional cube variable is reduced. Then, using a greedy algorithm (Algorithm 4 in Huang et al.’s paper), Huang et al. find some ordinary cube variables, that do not multiply together in the 1st round and do not multiply ...

1. Every screw should pass through a plate. 2. Each screw should engage a fragment on the opposite side that is also fixed to a plate. 3. As many screws as possible should be placed in the distal fragments. 4. Each screw should be as long as possible. 5. Each screw should engage as many articular fragments as possible. 6. The screws should lock together by interdigitation within the distal frag...

Since Bra�nemark et al published the results of a 10-year study on osseointegration in 1977, dental implants have increasingly been used to replace missing teeth. The use of osseointegrated implants had become a successful procedure for the treatment of complete, partial edentulism, and single-tooth replacements in both the anterior and posterior regions of the mouth. Although improvements in m...
متن کاملPostural Ergonomic Risk Assessment (Pera) in The Workers of the Automobile Parts Assembly Line: A New Observational Method for the Cube Model
Assembly lines are associated with health risk and musculoskeletal disorders, particularly in the upper limbs. The aim of this study was to analyze three risk factors of posture, duration and force by using the postural ergonomic risk assessment (PERA) method in the workers of the assembly unit of automobile parts. Material and Methods: This descriptive cross-sectional study was conducted in th...
متن کاملRemarks on the Pocklington and Padró-Sáez Cube Root Algorithm in 𝔽q
We clarify and generalize a cube root algorithm in Fq proposed by Pocklington [1], and later rediscovered by Padró and Sáez [2]. We correct some mistakes in [2] and give a full generalization of the result in [1, 2] for the cube root algorithm. We also give the comparison of the implementation of Pocklington and Padró-Sáez algorithm with two most popular cube root algorithms, namely the Adleman...
