The ramifications of the portal vein in the liver of horses were studied by using corrosion casting and gross dissection. The portal vein in the horse supplies the hepatic lobes by six major branches. The right lobe is supplied by three main branches, namely the dorsal diaphragmatic, the right caudodorsal and the right intermediate branches. The left branch supplies the left lateral and medial ...

The neural response to stimulus repetition is not uniform across brain regions, stimulus modalities, or task contexts. For instance, it has been observed in many functional magnetic resonance imaging (fMRI) studies that sometimes stimulus repetition leads to a relative reduction in neural activity (repetition suppression), whereas in other cases repetition results in a relative increase in acti...

The paper provides a novel approach to the design of nonuniform planar circular antenna arrays for achieving maximal side lobe level suppression and directivity. The current excitation amplitudes and phase perturbations of the array elements are determined using an Adaptive Memetic algorithm resulting from a synergy of Differential Evolution (DE) and Learning Automata that is able to significan...

The spectrum allocation policies of the Federal Communications Commission (FCC) [1] only allow spectrum access to primary users, it has been proven by various spectrum measurement campaigns that, the current spectrum usage across time and frequency is inefficient. Therefore, in order for the secondary users to access the unused portions of the licensed spectrum, the concept of “spectrum pooling...

Frequency diverse array-multiple-input multiple-output (FDA-MIMO) radar makes it transmit beam range–angle two-dimensional freedom by attaching a small frequency offset increment between the array elements. With widespread use of digital radio memory (DRFM) technology, is able to delay false target any range bin and doppler unit delaying forwarding transmits signals, resulting in deceptive jamm...

OBJECTIVE The cerebral network subserving repetition suppression (RS) of the P50 auditory evoked response as observed using paired-identical-stimulus (S1-S2) paradigms is not well-described. METHODS We analyzed S1-S2 data from electrodes placed on the cortices of 64 epilepsy patients. We identified regions with maximal amplitude responses to S1 (i.e., stimulus registration), regions with maxi...

Preliminary results are reported from an experimental study of the interaction between turbulence, sediment transport and bedform dynamics over the transition from dunes to upper stage plane beds. Over the transition, typical dunes changed to humpback dunes (mean velocity 0.8 ms-', depth 0.1 m, mean grain size 0.3 mm) to nominally plane beds with low relief bed waves up to a few mm high. All be...

conclusions the psychotic symptoms due to temporal lobe epilepsy can be resolved with lamotrigine administration. introduction visual illusions and hallucinations may accompany a wide variety of disorders with many various etiologies; therefore, they are nonspecific phenomena. in a partial seizure, a localized hyper synchronous neuronal discharge evolving into a partial seizure affecting a part...

anxiety and depression are very common in population and occur in a wide range of clinical states and is very common in epileptic patients. many recent epidemiological studies have found a high prevalence of depression and anxiety in epileptic patients. these studies found that epileptic patients suffered from depression and anxiety than those without epilepsy. the prevalence of depression or a...

Self-paced versions of many paradigms could have utility in probing cognitive systems. To validate several self-paced n-back paradigms, fourteen subjects performed four variations of the working memory task using visually presented letters as stimuli. Several areas in the frontal lobe, the anterior cingulate and a parietal network were consistently activated in the four variations: identity of ...
