Sex differences have been found in the anatomy of brains of a wide variety of vertebrates including humans. Common lore tells us that sex differences in the brain cause sex differences in behavior. This review entertains the possibility that sex differences in the brain may also do the exact opposite. Specifically, sex differences may allow males and females to display remarkably similar behavi...

We present the first BeppoSAX observation (0.1 to 220 keV) of the quasar Mrk 205. We have searched for the unusual Fe line profile claimed in the XMM-Newton spectrum which has been widely discussed in recent literature. We find no evidence for a broad, ionized Fe line component in our data. We detect for the first time a Compton hump in this object. Besides, when this component is included in t...

We study reaction-di¤usion systems of propagator-controller type in the one-dimensional unit interval. When propagator di¤uses slowly, we establish the existence of transition layer equilibria by using singular perturbation expansions and a Lyapunov-Schmidt reduction method. Our approach to the existence also enables us to simultaneously obtain a stability criterion for the layer equilibria.

Let λ ≥ 0 and n ∈ N \ {0} and consider the partition of (0,∞) into the halfopen intervals I1, I2, . . . where Ii = ((i − 1)/n, i/n]. Take a sequence X1, X2, · · · of independent random variables with Xi ∼ Bernoulli(λ/n), i.e., P (Xi = 1) = λ/n and P (Xi = 0) = 1− λ/n. We can interpret Xi = 1 to mean that a certain event was observed in the time period Ii. As n becomes large these time periods b...

BACKGROUND Two major distinct subsets of dendritic cells (DCs) are arranged to regulate immune responses: DEC-205+ DCs drive Th1 polarization and 33D1+ DCs establish Th2 dominancy. Th1 polarization can be achieved either by depletion of 33D1+ DCs with a 33D1-specific monoclonal antibody (mAb) or by activation of DEC-205+ DCs via intraperitoneal injection of α-galactosylceramide (α-GalCer). We s...

در این تحقیق که به دریافت سوررئالیست توسط نشریه ان ار اف بین سالهای 1924 تا 1940 اختصاص یافته است، قضاوت ان ار اف در باره وفاداران به نهضت سوررئالیست را طی این سالهای بحران فرهنگی مورد مطالعه قرار داده ایم. به عبارت دیگر، نشان داده ایم چگونه در روابط این دو گروه نو گرا، دوری بر نزدیکی غلبه یافت و دستاورد مثبت برخوردشان را برای فرهنگ فرانسه توضیح داده ایم از جمله: کار برد جدیدی از نقد ادبی و هنر...
