The rhombic lip (RL) is the neuroepithelium immediately adjacent to the roof plate of the fourth ventricle, and it gives rise to various brainstem and cerebellar cell types. Our study shows that the bHLH (basic helix-loop-helix) transcription factor Olig3 is expressed in the progenitors of RL, and ablation of Olig3 significantly affects the development of RL. In Olig3-/- caudal RL, the expressi...

The molecular programs that specify progenitors in the dorsal spinal cord remain poorly defined. The homeodomain transcription factor Gsh2 is expressed in the progenitors of three dorsal interneuron subtypes, dI3, dI4 and dI5 neurons, whereas Gsh1 is only expressed in dI4 and dI5 progenitors. Mice lacking Gsh2 exhibit a selective loss of dI3 interneurons that is accompanied by an expansion of t...

Introduction: Dental Cone beam CT (CBCT) is an imaging modality which has emerged as a 3D imaging modality of choice for osseous structures in the maxillofacial region. With increased usage of CBCT imaging for diagnosis and treatment planning, it is imperative that stringent dose assessments must be performed for dose estimation to safeguard both the patients and operating staf...

A signed k-partite graph (signed multipartite graph) is a k-partite graph in which each edge is assigned a positive or a negative sign. If G(V1, V2, · · · , Vk) is a signed k-partite graph with Vi = {vi1, vi2, · · · , vini}, 1 ≤ i ≤ k, the signed degree of vij is sdeg(vij) = dij = d + ij − d − ij , where 1 ≤ i ≤ k, 1 ≤ j ≤ ni and d + ij(d − ij) is the number of positive (negative) edges inciden...

Deutonura gibbosa, a new species of the phlegraea group, is described. It is characterized by a large elongate uneven tubercle Di on Abd. V, with chaetae Di1 and Di2 shift backward. It has otherwise the same chaetotaxic pattern as the subspecies sylvatica of D. deficiens. Deutonura gibbosa sp. nov. is the most widespread Deutonura in the Alps and southern Jura. Its barcode sequence is provided ...

At embryonic stages, Olig3 is initially expressed in the dorsal-most region of the spinal cord, but later in the ventral marginal zone as well. Previous studies indicated that Olig3 controlled the patterning of dorsal spinal cord and loss of Olig3 function led to the re-specification of dI2 and dI3 neurons into dI4 interneurons. However, the role of Olig3 in regulating the development of ventra...

Let 9 be a solvable Lie algebra over C and let oN be its algebraic adjoint group. The Dixmier map / is a bijective and continuous correspondence between the set 9 * / oN of coadjoint orbits and the set Prim 9 of all the primitive ideals of U(g). Actually the map / (which is the infinitesimal analog of the Kirillov orbits method [K, AK], has been defined by J. Dixmier [Dip Di2], the continuity o...

This paper considers Web content adaptation with a bandwidth constraint for server-based adaptive Web systems. The problem can be stated as follows: Given a Web page P consisting of n component items d1, d2, . . . ,dn and each of the component items di having Ji versions di1 ; di2 ; . . . ; diJi , for each component item di select one of its versions to compose the Web page such that the fideli...

Dual immersion programs have proven effective in achieving biliteracy for all students. However, maintaining equitable practices at the core of such has become more challenging remote learning due to pandemic. It is necessary, therefore, revise some benefits and challenges digital instruction mediated by technology these settings. Using a middle school Immersion (di) program Southern California...
