Using simple running models, researchers have argued that swing-leg retraction can improve running robot performance. In this paper, we investigate whether this holds for a more realistic simulation model validated against a physical running robot. We find that swing-leg retraction can improve stability and disturbance rejection. Alternatively, swing-leg retraction can simultaneously reduce tou...

PURPOSE Although several reports of supernumerary orbital muscles related to the levator palpebrae superioris have been published, no case has been associated with congenital eyelid retraction. This report describes an apparent causal relationship between an accessory levator muscle slip and congenital eyelid retraction. METHODS Case report and literature review. RESULTS Release of the anom...

Given an ideal in the local ring at a rational surface singularity, we define what it means for a collection of exceptional divisors on a fixed log resolution to critically contribute a jumping number. This is shown to be a numerical property of the collection, and can be used to give an explicit algorithm for finding all of the jumping numbers of the ideal. In addition, the jumping numbers of ...

In [13], Migliore–Miró-Roig–Nagel show that the Weak Lefschetz property can fail for an ideal I ⊆ K[x1, . . . , x4] generated by powers of linear forms. This is in contrast to the analogous situation in K[x1, x2, x3], where WLP always holds [16]. We use the inverse system dictionary to connect I to an ideal of fat points, and show that failure of WLP for powers of linear forms is connected to t...

We consider the fuzzification of the notion of an n-fold positive implicative ideal. We give characterizations of an n-fold fuzzy positive implicative ideal. We establish the extension property for n-fold fuzzy positive implicative ideals, and state a characterization of PIn-Noetherian BCK-algebras. Finally we study the normalization of n-fold fuzzy positive implicative ideals. 2000 Mathematics...

A fuzzy ideal on a set X is a non empty collection of subsets of X with heredity property which is also closed under arbitrary union and finite intersections. In this paper, we introduce a weak form of fuzzy ideals namely fuzzy pre-ideals and a way to obtain new fuzzy topologies is presented in this paper. Furthermore some interesting results for fuzzy ideals are generalized to fuzzy pre-ideal.

PURPOSE To investigate the causes of lower eyelid retraction and evaluate the outcomes of various surgical procedures. METHODS We conducted a retrospective medical record review of patients who underwent lower eyelid retraction surgery performed by a single surgeon at Kim's Eye Hospital between 2006 and 2013. We investigated the causes of lower eyelid retraction, clinical history, characteris...

Since Bellare and Ristenpart showed a multi-property preserving domain extension transform, the problem of the construction for multi-property hash functions has been reduced to that of the construction for multi-property compression functions. However, the Davies-Meyer compression function that is widely used for standard hash functions is not a multi-property compression function. That is, in...

On a pathological specimen of breast cancer cells, retraction artifact during histological processing mimics true lymphovascular invasion (LVI). The accurate determination of the presence or absence of LVI is a factor in determining risk of having a positive sentinel node, or having additional positive axillary nodes after a positive sentinel node biopsy in women with early-stage breast cancer....
