The class of Unambiguous Star-Free Regular Languages (UL) was defined by Schutzenberger as the class of languages defined by Unambiguous Polynomials. UL has been variously characterized (over finite words) by logics such as TL[Xa,Ya], UITL, TL[F,P], FO2[<], the variety DA of monoids, as well as partially-ordered two-way DFA (po2dfa). We revisit this language class with emphasis on notion of una...

OBJECTIVES The aim of this study was to investigate the use of off-label (OL) and unlicensed (UL) medicines to hospitalised children in Norway, to add to the current knowledge on use of medicines in this vulnerable patient group. METHODS The study was performed as a cross-sectional prospective study. Medication was classified as on- or off-label based on the comparison with the SmPC regarding...

Treatments for canine lymphoma often fail, because tumor cells acquire multidrug resistance (MDR). MDR can develop through several mechanisms, among which the overexpression of drug transporters in tumor cells is a well-studied mechanism. ATP-binding cassette sub-family G member 2 (ABCG2) belongs to the ABC-transporters, that are representative drug efflux pumps associated with MDR in human tum...

OBJECTIVES To evaluate the current status of ureteroscopic lithotripsy (UL) for treating renal calculi of >2 cm, as advances in flexible ureteroscope design, accessory instrumentation and lithotrites have revolutionised the treatment of urinary calculi. While previously reserved for ureteric and small renal calculi, UL has gained an increasing role in the selective management of larger renal st...

In a large-scale group communication networks, we propose a slotted-Aloha-based access control (SA-AC) scheme with the optimal transmission probability (TP) using the stochastic geometry. Since the performance of SA-AC scheme depends on the TP of the members in a group, the analytical model presents a joint view for the downlink (DL) and the uplink (UL) with TP of the members in a group. We pre...

[Purpose] Previous studies have reported on motor deficits in the ipsilateral upper limbs (UL) of a damaged brain hemisphere in motor tasks. However, little is known about sensory deficits on the ipsilateral side. Therefore, we investigated whether both motor and sensory function of the ipsilateral UL are affected in patients with stroke. [Subjects and Methods] Fifty patients with unilateral st...

To guarantee the success of massive multiple-input multiple-output (MIMO), one of the main challenges to solve is the efficient management of pilot contamination. Allocation of fully orthogonal pilot sequences across the network would provide a solution to the problem, but the associated overhead would make this approach infeasible in practical systems. Ongoing fifth-generation (5G) standardisa...

Uterine leiomyomata (UL), the most prevalent pelvic tumors in women of reproductive age, pose a major public health problem given their high frequency, associated morbidities, and most common indication for hysterectomies. A genetic component to UL predisposition is supported by analyses of ethnic predisposition, twin studies, and familial aggregation. A genome-wide SNP linkage panel was genoty...

OBJECTIVES To apply Rasch analysis to evaluate the psychometric properties of the composite score of the 3 upper limb subscales of the Motor Assessment Scale (UL-MAS) when administered in the acute/subacute phase post-stroke. DESIGN Prospective data collection of UL-MAS scores. PARTICIPANTS Eighty Eighty individuals a mean of 64.8 days (standard deviation 53.3; range 4-193 days) following t...

This single arm pre-post study aimed at evaluating the acute effects induced by a single session of robot-assisted passive hand mobilization on local perfusion and upper limb (UL) function in poststroke hemiparetic participants. Twenty-three patients with subacute or chronic stroke received 20 min passive mobilization of the paretic hand with robotic assistance. Near-infrared spectroscopy (NIRS...
