Resumen

A coupled neutronics thermal-hydraulics code NODAL3 has been developed based on the nodal few-group neutron diffusion theory in 3-dimensional Cartesian geometry for a typical pressurized water reactor (PWR) static and transient analyses, especially for reactivity initiated accidents (RIA).The spatial variables are treated by using a polynomial nodal method (PNM) while for the neutron dynamic solver the adiabatic and improved quasi-static methods are adopted. A simple single channel thermal-hydraulics module and its steam table is implemented into the code. Verification works on static and transient benchmarks are being conducted to assess the accuracy of the code. For the static benchmark verification, the IAEA-2D, IAEA-3D, BIBLIS and KOEBERG light water reactor (LWR) benchmark problems were selected, while for the transient benchmark verification, the OECD NEACRP 3-D LWR Core Transient Benchmark and NEA-NSC 3-D/1-D PWR Core Transient Benchmark (Uncontrolled Withdrawal of Control Rods at Zero Power). Excellent agreement of the NODAL3 results with the reference solutions and other validated nodal codes was confirmed

Resumen

Topological semimetals are characterized by symmetry-protected band crossings, which can be preserved in different dimensions in momentum space, forming zero-dimensional nodal points, one-dimensional nodal lines, or even two-dimensional nodal surfaces. Materials harboring nodal points and nodal lines have been experimentally verified, whereas experimental evidence of nodal surfaces is still lacking. Here, using angle-resolved photoemission spectroscopy (ARPES), we reveal the coexistence of Dirac nodal surfaces and nodal lines in the bulk electronic structures of ZrSiS. As compared with previous ARPES studies on ZrSiS, we obtained pure bulk states, which enable us to extract unambiguously intrinsic information of the bulk nodal surfaces and nodal lines. Our results show that the nodal lines are the only feature near the Fermi level and constitute the whole Fermi surfaces. We not only prove that the low-energy quasiparticles in ZrSiS are contributed entirely by Dirac fermions but also experimentally realize the nodal surface in topological semimetals.

Resumen

Abstract Background.—The term primary lymph node gastrinoma was first used to describe a group of patients with gastrin-producing tumors present in lymph nodes located in a well-defined anatomic region. The patients had no known primary tumors in the pancreas or gastrointestinal tract and had disease-free survival for up to 18 years. The anatomic region in question has a triangular shape that extends from the cystic and common bile ducts to the second and third portion of the duodenum and the neck and body of the pancreas. The term gastrinoma triangle was coined to identify the area; in addition, it was postulated that lymph nodes located in the gastrinoma triangle normally contained neuroendocrine cells capable of secreting gastrin and other neuropeptides. From its inception, the postulate became the subject of controversy. Design.—To extend previous observations, we examined the lymph nodes located in the gastrinoma triangle of 20 autopsy cases for the presence of neuroendocrine cells, as determined by immunohistochemistry, using antibodies to a panneuroendocrine substance (eg, synaptophysin) and a specific neuropeptide (eg, gastrin). Scanning for positive cells was performed by 2 observers (M.E.H. and M.C.C.). We compared the findings in these lymph nodes with lymph nodes obtained from axillary and inguinal dissections during surgical procedures. Results.—In all, 417 lymph nodes were studied. Five of the 20 gastrinoma triangle cases contained synaptophysin reactive cells, whereas 3 had gastrin reactive cells. None of the axillary and inguinal lymph nodes contained neuroendocrine cells. Conclusion.—Our findings support the hypothesis of entrapment of neuroendocrine cells during development and the presence of primary nodal gastrinomas.

Resumen

Benign vascular tumors arising primarily in lymph nodes are rare. The importance of identifying these entities is to avoid misdiagnosing them as malignant vascular tumors, which occur more often in lymph nodes. Hemangioma is a benign nodal vascular tumor, but its occurrence in lymph nodes is extremely rare. Hemangiomas can occur at any age, mostly in females. It is usually asymptomatic, affects only one node, and does not recur. Four histologic types of hemangioma have been identified: capillary/cavernous, lobular capillary, cellular, and epithelioid. This review highlights the key features of previously reported cases and discusses the differential diagnosis.

Resumen

The synthesis of this text comes from a contemporary appraisal of the term “the closet” and its current place in culture since the advent of cybernetics. The authors’ assertion is that this metaphor, one that is rooted in the iconography of the late-capitalist home, is in a moment of transition and constant redefinition. In this paper, the authors explore and assess three basic modern manifestations of the homosexual rite of passage and how they have been rendered obsolete, adapted, or in some respects, catalyzed by new media and mobile technology. The charting of these changes is evaluated as a ’nodal’ phenomenon within queer culture and is paired with Michel Foucault’s notion of heterotopia to better explore the spatial qualities of this shifting circumstance. The closet term is part of a continuum; one marked by intersecting moments of connectivity. In this article, the authors assess the term mainly in relation to a pre-computer era, a personal computer era and a mobile computer/smartphone era.

Resumen

As an alternative to nodal domains in the usual sense, we propose a partition of the domain of a real-valued eigenfunction in by trajectories of the gradient, linking saddle points to extrema. Its most elementary properties are listed and exemplified. The main point is that the problem of avoided crossings is largely eliminated.

Resumen

Na aula de 15 de janeiro de 1974 de O seminário, livro 21: les non-dupes errent, Lacan afirma a convergência do modal e do nodal. O objetivo deste trabalho é acompanhar as elaborações anteriores de seu ensino que permitiram tal conclusão, o que parece fundamental para a aproximação ao método borromeano e a suas implicações lógicas e linguísticas. Consideram-se as fórmulas da sexuação, presentes em O seminário, livro 20: mais ainda, como um matema de transição entre os discursos e a topologia borromeana. Essa transição é extremamente complexa, já que implica a construção de uma homologia entre a lógica e a topologia, interrogando a noção de linguagem compatível com a psicanálise. Trata-se de desenvolver a ideia de que o inconsciente é uma classe aberta e paradoxal, tal como Lacan desenvolve naquele seminário. Será preciso, portanto, acompanhar essa construção em três níveis: lógico, topológico e linguístico. Neste trabalho, será tratado apenas o nível lógico, deixando os demais para desenvolvimentos posteriores.

Resumen

We address with fluid-dynamical simulations using direct numerical techniques three important and fundamental questions with respect to fluid flow within the mouse node and left–right development. First, we consider the differences between what is experimentally observed when assessing cilium-induced fluid flow in the mouse node in vitro and what is to be expected in vivo . The distinction is that in vivo , the leftward fluid flow across the mouse node takes place within a closed system and is consequently confined, while this is no longer the case on removing the covering membrane and immersing the embryo in a fluid-filled volume to perform in vitro experiments. Although there is a central leftward flow in both instances, we elucidate some important distinctions about the closed in vivo situation. Second, we model the movement of the newly discovered nodal vesicular parcels (NVPs) across the node and demonstrate that the flow should indeed cause them to accumulate on the left side of the node, as required for symmetry breaking. Third, we discuss the rupture of NVPs. Based on the biophysical properties of these vesicles, we argue that the morphogens they contain are likely not delivered to the surrounding cells by their mechanical rupture either by the cilia or the flow, and rupture must instead be induced by an as yet undiscovered biochemical mechanism.
