This report describes AJ, a woman whose remembering dominates her life. Her memory is "nonstop, uncontrollable, and automatic." AJ spends an excessive amount of time recalling her personal past with considerable accuracy and reliability. If given a date, she can tell you what she was doing and what day of the week it fell on. She differs from other cases of superior memory who use practiced mne...
در بسیاری از موارد، استفاده از ریاضیات به معنای حل معادله می باشد. با ایم هدف، مهم تریم مساله ای که باید مورد توجه قرار گیرد آن است که آیا معادله ی مورد نظر جواب دارد یا خیر؟ برای مثال قضیه ی بولتزانو وجود حداقل یک ریشه را برای توابع پیوسته ای که روی یک بازه تعریف شده و در دو انتهای بازه مقادیر مختلف العلامه ای را اختیار می کنند، ایجاب می کند. امروزه، آنالیز غیرخطی و آنالیز غیر محدب کاربردهای ...
The life history characteristics of the rove beetle Paederus fuscipes Curtis were studied under laboratory conditions using three field strains from Malaysia: Desa Wawasan (DW), Sri Pinang (SP), and Ampang Jajar (AJ). The total development time of immature stages differed significantly among the three strains, especially between DW (17.43 +/- 0.16 d), SP (18.60 +/- 0.19 d), and AJ (18.68 +/- 0....
We prove the results stated in the main paper. We start by providing a brief summary of the notations used in the paper. Set [p] = {1, . . . , p} and for a subset J ⊂ [p], let |J | be its cardinality. Bold upper (resp. lower) case letters denote matrices (resp. vectors), and the same letter not bold represents its coefficients, e.g. aj denotes the jth entry of a. For an n × p matrix A with colu...
Exercise 1 (8 points) Show a sub-quadratic reduction from Convolution 3SUM to 3SUM. More precisely, show that if 3SUM can be solved in time O(n2− ) for some > 0, then Convolution 3SUM can be solved in time O(n2−δ) for some δ > 0. Solution : We are given a set A = {a1, a2, . . . , an} having n integers, we want to test whether there exist i, j ∈ [n] such that ai + aj = ai+j. We create a new set ...
Morphogenesis of epithelial tissues relies on the interplay between cell division, differentiation and regulated changes in cell shape, intercalation and sorting. These processes are often studied individually in relatively simple epithelia that lack the complexity found during organogenesis when these processes might all coexist simultaneously. To address this issue, we are making use of the d...
Crystal Structure, EPR Studies, Tetraphenylarsonium [Bis-( 1,3-dithia-2-one-4,5-dithiolato)-nickelate] The crystal structure of (AsPh4)[Ni(dmid)2] (dmid ~ = 1,3-dithia-2-one-4,5-dithiolato) has been determined by X-ray diffraction studies: crystals are monoclinic, space group P2,//i, a = 14.724(2), b = 14.305(5), c = 15.570(3) k , ß = 92.20(1)°, V = 3277 Ä, ov = 1.63 gem 3 for Z = 4, final conv...
Some gastropod specimens belonging to the planorbid genus Ferrissia were recently collected in Lebanon and in Iraq, where the autochthonous species Ferrissia clessiniana (Jickeli, 1882) is supposed to occur. The molecular identification of collected specimens proved that they belong to the allochthonous species Ferrissia fragilis (Tryon, 1863), the protagonist of a dramatic cryptic invasion whi...
In src- and ras-transformed cells, tyrosine phosphorylation of adherens junction (AJ) components is related to impairment of cell-cell adhesion. In this paper we report that in human endothelial cells (EC), tyrosine phosphorylation of AJ can be a physiological process regulated by cell density. Immunofluorescence analysis revealed that a phosphotyrosine (P-tyr) antibody could stain cell-cell ju...
Schizophrenia is a common, clinically heterogeneous disorder associated with lifelong morbidity and early mortality. Several genetic variants associated with schizophrenia have been identified, but the majority of the heritability remains unknown. In this study, we report on a case-control sample of Ashkenazi Jews (AJ), a founder population that may provide additional insights into genetic etio...
