Purpose: To compare the post-extraction dimensional changes following extraction alone or extraction plus ridge preservation with an intrasocket mineralized freeze-dried bone allograft and a collagen membrane. 2 purpose is to determine whether there are significant differences between 2 procedures histologically.3 one is that a 4-monts and 6month implant placement time was evaluated to determin...

آنالیز تصاویر چندزمانه سنجش از دور، تکنیک کارآمدی برای شناسایی تغییرات کاربری و پوشش اراضی در مناطق شهری می باشد. جدا از تکنیک بکار رفته برای شناسایی تغییرات،فضای ویژگی تأثیر بسیار زیادی در صحت نتایج دارد. حصول نتایج رضایت بخش در شناسایی تغییرات مناطق شهری، مستلزم بکارگیری ویژگی‏ های طیفی و مکانی (بافت) بهینه می‏ باشد. اگرچه جستجوی سراسری تنها تضمین دست یابی به مجموعه ویژگی های بهینه است، ولی د...

The rapid growth in the number of users of mobile communications means that many operators must find new ways of increasing the capacity of their networks. Their options include allocating more frequency, introducing frequency-hopping techniques, and adding microcells and adaptive antenna systems. The introduction of new frequency bands at 1800 and 1900 MHz is an example of allocating frequency...

Explicit formulas for general order multivariate Padé approximants of pseudo-multivariate functions are constructed on specific index sets. Examples include the multivariate forms of the exponential function E (x) = ∞ ∑ j1,j2,...,jm=0 x1 1 x j2 2 · · ·x jm m (j1 + j2 + · · ·+ jm)! , the logarithm function L(x) = ∑ j1+j2+···+jm≥1 x1 1 x j2 2 · · ·x jm m j1 + j2 + · · ·+ jm , the Lauricella funct...

Orthogonal frequency division multiplexing with subcarrier number modulation (OFDM-SNM) has been recently proposed to improve the spectral efficiency (SE) of traditional OFDM system. In this paper, we propose a joint-mapping OFDM-SNM (JM-OFDM-SNM) scheme transmit signal vector constant length information bits by jointly considering activation patterns and constellation symbols. A low-complexity...

This paper proposes a novel hyperspectral matching algorithm by integrating the stochastic Jeffries-Matusita measure (JM) and the deterministic Spectral Angle Mapper (SAM), to accurately map the species and the associated landcover types of the mangroves of east coast of India using hyperspectral satellite images. The JM-SAM algorithm signifies the combination of a qualitative distance measure ...

BACKGROUND JM-1232(-) is a novel anesthetic agent which acts through gamma-aminobutyric acid receptors. Cerebral pial vascular effects of JM-1232(-) are unknown. We thus evaluated topical and intravenous effects of JM-1232(-) on cerebral pial microvessels in rabbits, and the extent to which carbon dioxide (CO2) reactivity is preserved. METHODS Closed cranial windows were used to visualize cer...

The significance of ErbB4 in tumor biology is poorly understood. The ERBB4 gene is alternatively spliced producing juxtamembrane (JM-a and JM-b) and cytoplasmic (CYT-1 and CYT-2) isoforms. Here, signaling via the two alternative ErbB4 JM isoforms (JM-a CYT-2 and JM-b CYT-2) was compared. Fibroblasts expressing ErbB4 JM-a demonstrated enhanced ErbB4 autophosphorylation, growth, and survival. In ...
