Many applications often require finding sets of entities of interest that meet certain constraints. Such set-based queries (SQs) can be broadly classified into two types: optimization SQs that involve some optimization constraint and enumerative SQs that do not have any optimization constraint. While there has been much research on the evaluation of optimization SQs, there is very little work o...

OBJECTIVES The aim of this study was to evaluate the association between two semi-quantitative Doppler US scoring systems (SQS), and the quantitative scoring (QS) of Doppler pixel count. METHODS Adult patients with RA and inadequate clinical response to anti-rheumatic therapy were examined with musculoskeletal US (MSUS). Dorsal MSUS of the wrists, MCP and MTP 2-5 were performed. MSUS images w...

BACKGROUND The multiple mini-interview (MMI) is increasingly used for postgraduate medical admissions and in undergraduate settings. MMIs use mostly Situational Questions (SQs) rather than Past-Behavioural Questions (PBQs). A previous study of MMIs in this setting, where PBQs and SQs were asked in the same order, reported that the reliability of PBQs was non-inferior to SQs and that SQs were mo...

Abstract. In this paper we present a graph theoretic construction of Steiner quadruple systems (SQS) admitting abelian groups as point-regular automorphism groups. The resulting SQS has an extra property which we call A-reversibility, where A is the underlying abelian group. In particular, when A is a 2-group of exponent at most 4, it is shown that an A-reversible SQS always exists. When the Sy...

The present study aimed to elucidate the molecular mechanisms underlying the induction of cytotoxic effects by sasanquasaponin (SQS) in HepG2 cells. Following SQS treatment, time- and dose-dependent increases in the apoptotic rate were observed. The induction of cell death by SQS mainly occurs via programmed cell death, as indicated by Annexin V-fluorescein isothiocyanate and propidium iodide s...

A self quenching streamer (SQS), or limited streamer mode has been studied in single wire chambers with cross-sections 12·12 mm and wire diameters 15, 25 and 50 μm. Chambers were filled with either pure dimethyl ether (DME) or isobutane gases and irradiated with Gd alpha and Fe x-ray sources. Clear transitions from a proportional to 100% SQS mode were observed on all three diameter wires with b...

A new algebraic structure (P ; q) of a Steiner quadruple systems SQS (P ; B) called an SQS-3-groupoid with q(x, x, y) = x (briefly: an SQS-3-quasigroup) is defined and some of its properties are described. Sloops are considered as derived algebras of SQS-skeins. Squags and also commutative loops of exponent 3 with x(xy) = y given in [7] are derived algebras of SQS-3-groupoids. The role of SQS-3...

In today’s world distributed message queues is used in many systems and play different roles such as content delivery, notification system and message delivery tools. It is important for the queue services to be able to deliver messages in larger scales, at the same time it must be highly scalable and provide parallel access at the same time. An example of a commercial state of the art distribu...

Digital breast tomosynthesis (DBT) was developed to alleviate the problem of overlapping tissue in 2-D mammography. To improve DBT image quality, we are developing model-based iterative reconstruction method based on models of the imaging system physics. Our preliminary implementation (SQS-DBCN) incorporated detector blur into the system model and correlation into the noise model under some sim...

BACKGROUND Chronic radicular pain can be effectively treated with spinal cord stimulation, but this therapy is not always sufficient for chronic back pain. Subcutaneous nerve stimulation (SQS) refers to the placement of percutaneous leads in the subcutaneous tissue within the area of pain. Case series data show that failed back surgery syndrome (FBSS) patients experience clinically important le...
