Introduction Recurrent complex visual hallucinations are a core clinical feature of dementia with Lewy bodies(DLB)and are typically well-formed,often consisting of figures,such as people or animals(1)Despite the profound impact upon patients and caregivers in DLB,the aetiopathology of visual hallucinations remains largely *** this article we discuss the anatomy of the human visual system,hypotheses of the genesis of visual hallucinations in DLB,and imaging and neuropathological studies that have attempted to understand visual hallucinations on a functional and anatomical basis.

The Belt and Road Initiative has become associated with a geopolitical "China threat"discourse in the South Pacific. Are China and Australia,the dominant regional player in the South Pacific, driven by geopolitical imperatives to compete for power or do their different geopolitical needs provide opportunity for cooperation that is mutually beneficial and manages risks in the region? Supposed Chinese "threats"as well as risks to China are examined,including fears of a military base in Vanuatu,Chinese debt-funded projects in Tonga and closer economic cooperation with Papua New Guinea. A geopolitical analysis concludes that it is feasible for Australia to meet its geopolitical imperatives if its regional security leadership can be maintained. A geopolitical analysis of China in the South Pacific concludes that China is unlikely to seek regional security leadership if it can ensure access to trade routes and markets. If Australia could move beyond geopolitical rhetoric,it should therefore be possible for Australia to partner with China to support sustainable development,mitigate risks and ensure broader stability of the South Pacific region.

BACKGROUND This is a unique case of a patient who was found to have two extremely rare primary malignancies synchronously,i.e.,an ampullary adenocarcinoma arising from a high-grade dysplastic tubulovillous adenoma of the ampulla of Vater(TVAoA)with a high-grade ileal gastrointestinal stromal tumor(GIST).Based on a literature review and to the best of our knowledge,this is the first report of this *** ampullary tumors are extremely rare,with an incidence of four cases per million population,which is approximately 0.0004%.Distal duodenal polyps are uncommon and have a preponderance of occurring around the ampulla of *** adenoma of the ampulla(AoA)may occur sporadically or with a familial inheritance pattern,as in hereditary genetic polyposis syndrome such as familial adenomatous polyposis syndrome(FAPS).We report a case of a 77-year-old male who was admitted for painless obstructive jaundice with a 40-pound weight loss over a two-month period and who was subsequently diagnosed with two extremely rare primary malignancies,i.e.,an adenocarcinoma of the ampulla arising from a high-grade TVAoA and a high-grade ileal GIST found *** SUMMARY A 77-year-old male was admitted for generalized weakness with an associated weight loss of 40 pounds in the previous two months and was noted to have painless obstructive *** physical examination was benign except for bilateral scleral and palmar *** results were significant for an obstructive pattern on liver *** lipase and carbohydrate antigen-19-9 levels were *** tomography(CT)of the abdomen and pelvis and magnetic resonance cholangiopancreatography were consistent with a polypoid mass at the level of the common bile duct(CBD)and the ampulla of Vater with CBD *** same lesions were visualized with endoscopic retrograde *** of endoscopic forceps biopsy showed *** of the surgical specimen of the

The past decade has seen an unprecedented increase in our understanding of the biology and etiology of head and neck squamous cell carcinomas(HNSCC).Genome-wide sequencing projects have identified a number of recurrently mutated genes,including unexpected alterations in the NOTCH pathway and chromatin related ***-expression profiling has identified 4 distinct genetic subtypes which show some parallels to lung squamous cell carcinoma *** identification of the human papilloma virus as one causative agent in a subset of oropharyngeal cancers and their association with a favorable prognosis has opened up avenues for new therapeutic *** expanding knowledge of the underlying molecular abnormalities in this once very poorly understood cancer should allow for increasingly rational clinical trial design and improved patient outcomes.

A type of wavelet neural network, in which the scale function isadopted only, is proposed in this paper for non-linear dynamicprocess modelling. Its network size is decreased significantly andthe weight coefficients can be estimated by a linear algorithm. Thewavelet neural network holds some advantages superior to other typesof neural networks. First, its network structure is easy to specifybased on its theoretical analysis and intuition. Secondly, networktraining does not rely on stochastic gradient type techniques andavoids the problem of poor convergence or undesirable local minima.

The packaging poses a critical challenge for commercialization of MEMS products. Major problems with the packaging process include degraded reliability caused by the excess stress due to thermal mismatch and altered performance of the MEMS device after packaging caused by thermal exposure. The localized laser bonding technique for ceramic MEMS packaging to address above-mentioned challenges was investigated. A continuous wave CO2 laser was used to locally heat sealing material for ceramic MEMS package lid to substrate bonding. To determine the laser power density and scanning speed, finite element analysis thermal models were constructed to simulate the localized laser bonding process. Further, the effect of external pressure at sealing ring on the bonding formation was studied. Pull testing results show that the scanning speed and external pressure have significant influence on the pull strength at the bonding interface. Cross-sectional microscopy of the bonding interface indicates that the packages bonded with relatively low scanning speed and external pressure conditions have higher bonding quality. This research demonstrates the potential of localized laser bonding process for ceramic MEMS packaging.
