The role of the pectoral fin bud for outgrowth by fin axons was assessed by ablation of pectoral fin buds and by transplantation of fin buds to ectopic sites in the embryos of the Japanese medaka fish (Oryzias latipes). Normally nerves from segments 1-4 (S1-4) and less frequently the S5 nerve converged at the base of the fin bud by extending toward the fin bud on the ventral surface of the axia...

For a long time, the ultra-sharp tips are used for high resolution microscope, such as scanning tunneling microscope (STM), atomic force microscope (ATM), field emission scanning electron microscope (FE-SEM). In addition, helium ion microscope (HIM), which has sub-nanometer imaging resolution, employs the tip as gas field ionization source (GFIS) in recent years. There are a lot of required vit...

Passive cooling of electronics systems requires the use fins and spines. Improved heat transfer enhancements in have been achieved through porosity, magnetic field, functionally graded materials, etc. However, space time-dependent analysis passive device with inherent nonlinearities explorations conditions at tip not fully presented. Therefore, this work presents an application hybrid computati...

In this paper we examine the stability of silicon tip apices by using density functional theory (DFT) calculations. We find that some tip structures - modelled as small, simple clusters - show variations in stability during manipulation dependent on their orientation with respect to the sample surface. Moreover, we observe that unstable structures can be revealed by a characteristic hysteretic ...

Species of the gobiid genus Schindleria are among smallest and fastest reproducing vertebrates oceans. We describe a new species, qizma , from Red Sea, Saudi Arabia. It is an extreme example progenesis, within already paedomorphic genus, with morphological traits clearly differentiating it its congeners. has unique, unflexed notochord straight urostyle which tip inserted into hypural cartilage,...

We investigate a technology to create a high temperature heat source on the tip surface of the glass fiber proposed for medical surgery applications. Using 4 to 6 W power level semiconductor lasers at a wavelength of 980 nm, a laser coupled fiber tip was preprocessed to contain a certain amount of titanium oxide powder with a depth of 100 μm from the tip surface so that the irradiated low laser...

According to manufacturers of both magnetic resonance imaging (MRI) machines, and implantable neurological pulse generators (IPGs), MRI is contraindicated for patients with IPGs. A major argument for this restriction is the risk to induce heat in the leads due to the electromagnetic field, which could be dangerous for the surrounding brain parenchyma. The temperature change on the surface of th...

We report on a systematic study of highly enhanced optical field and its induced thermal transport in nanotips under laser irradiation. The effects on electric field distribution caused by curvature radius, tip aspect ratio, and polarization angle of the incident laser are studied. Our Poynting vectors' study clearly shows that when a laser interacts with a metal tip, it is bent around the tip ...

OBJECTIVE To determine the effectiveness of Tip-therm, a temperature discriminator, in making an early diagnosis of distal symmetrical polyneuropathy in diabetic patients and to compare its effectiveness with the Semmes-Weinstein monofilament and biothesiometry, which are established methods of diagnosing neuropathy in diabetic patients. PATIENTS AND METHODS From the diabetic subjects who cam...
