Solving the famous Hermite, Legendre, Laguerre and Chebyshev equations requires different techniques of unique character for each equation. By reducing these differential equations of second order to a common solvable differential equation of first order, a simple common solution is provided to cover all the existing standard solutions of these named equations. It is easier than the method of generating functions and more powerful than the Probenius method of power series.

Silica is a versatile pigment for ink jet media. Micronized silica gel is the worldwide standard for high performance matte ink jet media. For glossy ink jet media, several different forms of silica are widely used. Submicron silica gel dispersions, with either anionic or cationic surfaces, can be employed in either absorptive basecoat layers or in the glossy ink receptive top layer. Colloidal silica, with a variety of particle sizes and surface modifications, is utilized extensively in glossy top layers. It will show how various silica pigments can be utilized in glossy ink receptive coatings, both in cast based glossy media and RC based glossy media. Several novel silica pigments will be examined by relating the physical properties of the pigments and the formula variables to the print quality of the ink jet media.

The separation of protein enzymatic digests by RPHPLC is a standard method in protein research and in the development of well-characterized biotechnology pharmaceuticals. Resolution on silicabased RP columns is determined by the nature of the silica, as well as, the silanes and the chemistry that is used to bond them to the stationary phase. Typically, 300A C18 chemistries have carbon coverage ranging from 2.8 to 3.6 μmol/m2. The performance of a novel, monomeric bonded 300A C18 adsorbent with carbon coverage > 4 μmol/m2 is described. The resolution and sensitivity of this stationary phase was assessed using an LC-MS/MS analysis of several tryptic digests including: di

Background Racial disparities in cardiovascular conditions are well *** similar race-based discrepancies in health outcomes also exist among elderly patients undergoing surgical aortic valve replacement(SAVR) for aortic stenosis remains *** We abstracted data from the National(Nationwide) Inpatient Sample over a 20-year period from 2001 to 2020 using specific ICD-9 and ICD-10 *** included patients aged ≥ 60 and ≤ 80 years with races recorded as White,African American,or Hispanic at the time of their hospitalization for *** analyzed and reported the baseline characteristics,risk-adjusted inhospital mortality,and complications stratified by *** Of 420,181 patients studied,90.0% identified as White,4.0% as African American and 6.0% as *** a decrease in overall in-hospital mortality rates from 3.8% between 2001-2005 to 1.8% between 2016-2020,African Americans had higher odds of all-cause in-hospital deaths compared to Whites(a OR = 1.390,P < 0.001).Additionally,they were more likely to experience cardiogenic shock(a OR = 1.241,P < 0.001) and acute kidney injury(a OR = 1.314,P < 0.001) as well as more likely to require organ support such as IABP use(a OR = 1.336,P < 0.001) or invasive mechanical ventilation(a OR = 1.342,P < 0.001).Interestingly,African Americans were less likely to report events of acute ischemic stroke compared to Whites(a OR = 0.852,P < 0.001).Conclusions Despite a reassuring reduction in overall in-hospital mortality rates of geriatric patients undergoing SAVR for aortic stenosis,racial disparities in health outcomes remain pervasive with minorities more likely to report higher in-hospital morbidity and mortality.

Performance and reliability ofa 2 transistor Si nanocrystal nonvolatile memory （NVM） are investigated. A good performance of the memory cell has been achieved, including a fast program/erase （P/E） speed under low voltages, an excellent data retention （maintaining for 10 years） and good endurance with a less threshold voltage shift of less than 10% after 104 P/E cycles. The data show that the device has strong potential for future embedded NVM applications.

As SOI-CMOS technology nodes reach the tens ofnanometer regime, body-contacts become more and more ineffective to suppress the floating body effect. In this paper, self-bias effect as the cause for this failure is analyzed and discussed in depth with respect to different structures and conditions. Other alternative approaches to suppressing the floating body effect are also introduced and discussed.

This paper presents a computational fluid dynamics approach for micro droplet impacting on a flat dry surface. A two-phase flow approach is employed using FLUENT VOF multiphase model to calculate the flow distributions upon impact. The contact line velocity is tracked to calculate the dynamic contact angle through user defined function program. The study showed that the treatment of contact line velocity is crucial for the accurate prediction of droplet impacting on poor wettability surfaces. On the other hand, it has much less influence on the simulation of droplet impacting on good wettability surfaces. Good fit between simulation results and experimental data is obtained using this model.
