Second-order stochastic dominance (SSD) is widely recognised as an important decision criterion in portfolio selection. Unfortunately, stochastic dominance models are known to be very demanding from a computational point of view. In this paper we consider two classes of models which use SSD as a choice criterion. The first, proposed by Dentcheva and Ruszczyński (2006), uses a SSD constraint, wh...

Saikosaponin-d (Ssd) is a triterpenoid saponin derived from Bupleurum falcatum L., which has been shown to exhibit a variety of pharmacological properties, including anti-inflammatory, antibacterial and antiviral properties. The aim of the present study was to investigate the effect of Ssd on the differentiation, maturation and function of human monocyte-derived dendritic cells (DCs) isolated f...

Researchers have long been enthralled with the idea that gene duplication can generate novel functions, crediting this process with great evolutionary importance. Empirical data shows that whole-genome duplications (WGDs) are more likely to be retained than small-scale duplications (SSDs), though their relative contribution to the functional fate of duplicates remains unexplored. Using the map ...

In a shared virtualized storage system that runs heterogeneous VMs with diverse IO demands, it becomes a problem for the hypervisor to cost-effectively partition and allocate SSD resources among multiple VMs. There are two straightforward approaches to solve this problem: either equally assigning SSDs to each VM or managing SSD resources in a fair competition mode. Unfortunately, they cannot fu...

BACKGROUND Subsyndromal symptomatic depression (SSD) is a subtype of subthreshold depressive and can lead to significant psychosocial functional impairment. Although the pathogenesis of major depressive disorder (MDD) and SSD still remains poorly understood, a set of studies have found that many same genetic factors play important roles in the etiology of these two disorders. Nowadays, the diff...

delirium might be an exceptionally good marker for comorbid diseases. In fact, in the bivarite analysis only the CIRS-G was associated with mortality. Previous studies have shown that there is evidence for a disease spectrum between delirium and SSD, but our study fails to show this spectrum. Our population study is considerably older and shows a higher prevalence of functional and cognitive im...

LLE Review, Volume 114 73 Introduction Polar-drive (PD)1–4 implosions on the National Ignition Facility (NIF) require smoothing of the laser-imposed nonuniformities. The spot shape on target is controlled by employing distributed phase plates (DPP’s).5,6 Smoothing by spectral dispersion (SSD)7–9 smoothes the far-field speckle pattern in a time-integrated sense by continuously changing the near-...

BACKGROUND Several epidemiological studies have shown that cannabis; the most widely used illegal drug in the world, is associated with schizophrenia spectrum disorders (SSD). AIMS To assess the characteristics of cannabis use and its association with SSD in a cohort of psychiatrically ill patients and discuss the implications for policy development METHODS This is a retrospective analytica...

Autism spectrum disorders (ASD) and schizophrenia spectrum disorders (SSD) share clinical and genetic components that have long been recognized. The two disorders co-occur more frequently than would be predicted by their respective prevalence, suggesting that a complex, multifactor association is involved. However, DSM-5 maintains the distinction between ASD, with core social and communication ...

We present a demonstration about optimizing two database storage engines by leveraging multi-streamed SSDs (MS-SSD in short). By storing data pages with similar lifetime together in the same physical ash blocks, MS-SSD can e ectively reduce the overhead of garbage collection, improving the write performance and prolonging the lifespan. Thus, in order to bene t from MS-SSD, it is very crucial fo...
