Amelanotic at such locations can be misdiagnosed both clinically radiologically. Therefore, histopathological examination immunohistochemistry mandatory for the diagnosis these tumors. diagnosed this using histopathology confirmed based on presence immunohistochemical markers human melanoma black 45 (HMB45)...

The 2015 WHO classification classifies neuroendocrine tumours (NET) of the lung into typical carcinoid, atypical large cell carcinoma and small based on morphology alone. Mitosis is major parameter for this classification, thus several studies have focused role Ki67 in these but without conclusive results. aim study was to categorize assess utility diagnosis.The included 42 cases (23 biopsies 19 lobectomy specimens) (excluding carcinoma). Haematoxylin & eosin stained sections,...

One of the remaining challenges for commercialization EUV lithography is lifetime Mo/Si multilayer optics and masks. The dominated by carbon contamination on surfaces optics, which caused residual hydrocarbons in vacuum chamber when are exposed to radiation. possible sources resist outgassing. To be able understand type harmful mirror reflectivity, three hydrocarbon species - benzene, tert-butanol diphenyl sulfide thought representative commonly outgassed from photoresist were selected. goal...

Optics contamination is a concern for extreme ultraviolet (EUV) lithography. To protect EUV optics, all materials used in vacuum exposure chambers must be screened prior to use. This paper will briefly describe the methods measure resist outgassing and list most frequently encountered species of current resists. The first attempts implement witness plate experiments show that difference between control samples not substantial Si-capped mirrors are stable. Actual microexposure tool...

The Mo/Si multilayer mirrors used for extreme ultraviolet (EUV) lithography can become contaminated during exposure in the presence of some hydrocarbons [1-3]. Because this leads to a loss reflectivity optics and throughput tools, it needs be avoided. Since photoresists are known outgas EUV radiation vacuum environment, careful choice materials is important preserving optics. Work therefore has been performed measure species quantities molecules that from resists when exposed [4-7].

The impact of carbon contamination on extreme ultraviolet (EUV) masks is significant due to throughput loss and potential effects imaging performance. Current research primarily focuses the lifetime multilayer surfaces, determined by reflectivity reduced in EUV exposure tools. However, patterned can cause additional absorbing features printed images, as well impacting efficiency cleaning process. In this work, several different techniques were used determine possible topography. Lithographic...

Lipid-rich carcinoma of the breast is a rare form invasive special type. Most cases are grade 3, hormone receptor negative, and associated with aggressive clinical behavior. We report an unusual case lipid-rich morphological immunophenotypical features different from those reported so far in literature. The index underscores fact that there no consensus regard to exact nature this tumor. Hence, larger studies needed draw meaningful conclusions.

Purpose This study aims to examine the psycho-emotional and social experiences of caregivers children with autism spectrum disorder. Various facets caregiving experience are explored, including feelings thoughts parents/caregivers, such as resilience experienced in their journey, how they coped challenges also positive experiences. Design/methodology/approach In this study, these aspects broadly probed using semi-structured interviews subjected narrative analysis. Lastly, there is a focus on...

Nocardia has been recognized as a significant opportunistic pathogen in organ transplant patients; however, it is an uncommon immunocompetent patients. It may mimic other infectious diseases both clinically and radiologically. We report four cases of pulmonary nocardiosis three immunocompromised one patients on fine-needle aspiration cytology (FNAC). Two presented with lung consolidation while two had cavitatory lesions. FNAC smears showed inflammatory cells composed polymorphs histiocytes...

Extreme ultraviolet (EUV) lithography is one of the most promising candidates for device patterning at 22 nm halfpitch node. The contamination extreme optics has consistently been listed among top challenges commercialization EUV lithography. In a exposure tool under radiation exposure, two main mechanisms that degrade reflectivity molybdenum/silicon multilayer are carbonization and oxidation. accumulation carbon on mirror surfaces consequence residual hydrocarbons and/or other containing...

Typical extreme ultraviolet (EUV) photoresist is known to outgas carbon-containing molecules, which of particular concern the industry as these molecules tend contaminate optics and diminish reflectivity. This prompted extensive work measure species quantities that they in a vacuum environment. Experiments were performed test whether outgassing rate directly proportional at EUV photons arrive very high power exposure will cause same amount much lower with dose unchanged.

We describe a null-field ellipsometric imaging system (NEIS) that provides for the real-time of carbon deposition profiles on extreme-ultraviolet (EUV) optics in vacuum system. NEIS has been demonstrated at NIST small chamber is used EUV lifetime testing. The images spots with sub-nanometer resolution thickness measurements maintain good agreement those from ex-situ spectral ellipsometry (SE) and x-ray photoelectron spectroscopy (XPS). will be implemented several synchrotron beamlines...

Crytococcus neoformans is an encapsulated yeast that frequently affects immune-compromised patients, although increasingly being detected in the immune-competent host as well. We report a case of disseminated cryptococcosis young child whom no immune deficiency was yet identified. A 4-year-old presented with high-grade fever, intermittent abdominal pain and generalized skin eruptions for past two months. He had pallor, firm lymphadenopathy, lesions scarring hepatosplenomegaly.

Optics contamination remains one of the challenges in extreme ultraviolet (EUV) lithography. In addition to desired wavelength near 13.5 nm (EUV), plasma sources used EUV exposure tools emit a wide range out-of-band (OOB) wavelengths extending as far visible region. We present experimental results rates and OOB light using Xe source filters. Employing heated carbon tape hydrocarbons, we have measured dependence on Ru-capped mirror. These are compared TiO₂ ZrO₂ capping layers.
