Plus-minus lid syndrome.

Plus minus lid syndrome with ataxia.

Plus minus lid syndrome is an ocular syndrome characterized by unilateral ptosis and contralateral lid retraction. Also when the ipsilateral lid is raised manually, the contralateral retracted lid does not revert. This patient presented with features of plus minus lid syndrome with ataxia due to a vascular mesencephalic lesion.

A rare midbrain infarction presenting with plus-minus lid syndrome with ataxia: a case report

INTRODUCTION We present the case of a patient with midbrain infarction with an unusual clinical presentation, where clinical diagnosis and anatomical localization were valuable tools in deciding treatment. CASE PRESENTATION Our patient was a 59-year-old, right-handed Caucasian man with hypertension who presented to our facility with acute diplopia that persisted until he developed complete ri...

Remarks on the plus-minus weighted Davenport constant

For (G,+) a finite abelian group the plus-minus weighted Davenport constant, denoted D±(G), is the smallest l such that each sequence g1 . . . gl over G has a weighted zero-subsum with weights +1 and −1, i.e., there is a non-empty subset I ⊂ {1, . . . , l} such that ∑ i∈I aigi = 0 for ai ∈ {+1,−1}. We present new bounds for this constant, mainly lower bounds, and also obtain the exact value of ...

Improving Modular Inversion in RNS Using the Plus-Minus Method

The paper describes a new RNS modular inversion algorithm based on the extended Euclidean algorithm and the plus-minus trick. In our algorithm, comparisons over large RNS values are replaced by cheap computations modulo 4. Comparisons to an RNS version based on Fermat’s little theorem were carried out. The number of elementary modular operations is significantly reduced: a factor 12 to 26 for m...
