Objective: An effective pain control is important in early mobilization and returning to normal daily life following percutaneous nephrolithotomy (PCNL) operations. The use of an intraoperative local anaesthetic or postoperative analgesic has been reported for pain control in PCNL. Transmuscular quadratus block (QLB III) is a regional anaesthetic technique applied under ultrasound guidance. The aim of this study was to investigate the effectiveness of QLB III on postoperative pain in PCNL...

OBJECTIVES: Quadratus Lumborum Block in contrast to Transversus Abdominis Plane Block contains a unique component which not only stops somatic pain but also inhibits visceral pain by spreading the local anesthetic to the paravertebral space. This study was designed to determine whether performing the Quadratus Lumborum Block type I in patients un-dergoing cesarean section would be associated with both decreased morphine consumption and decreased pain levels in the postoperative 48-hour period...

BACKGROUND AND OBJECTIVES: Several types of quadratus lumborum block (QLB) are used for postoperative analgesia and are believed to be effective against both somatic and visceral pain via a local anesthetic (LA) effect in the paravertebral space (PVS). However, it remains unclear whether all QLB techniques result in LA spread into the PVS. We hypothesized that LA administered via intramuscular QLB would spread into the paravertebral space and investigated the spread and sensory block area of LA in intramuscular QLB...

We compute electrical and thermal conductivities of hydrogen plasmas in the nondegenerate regime using Kohn-Sham density functional theory (DFT) and an application of the Kubo-Greenwood response formula, and demonstrate that for thermal conductivity, the mean-field treatment of the electron-electron (e-e) interaction therein is insufficient to reproduce the weak-coupling limit obtained by plasma kinetic theories. An explicit e-e scattering correction to the DFT is posited by appealing to Matthiessen's Rule and the results of our computations of conductivities with the quantum Lenard-Balescu (QLB) equation...

The Qehan Lake Basin (QLB) and its system of lakes are located in a marginal monsoon zone and are extremely sensitive to global climate change. In this paper, using aerial photographs from different periods, in addition to MSS, TM, and ETM images, and combining these with regional topographic maps, we analyze lake area changes from 1958 to 2010 and the relation between Qehan Lake (QL) and climate variability. Our results indicate that there was a relatively high lake level in 1959, when the area and volume of the lake were 118...

In this article, we examine the ways in which 18 queer, lesbian, and bisexual (QLB) women in Eastern Canada negotiated their visibility in interactions with primary care providers. QLB women patients used a number of strategies to determine risk and to be visible or invisible to their health care providers. We describe participants' disclosure decisions and strategies, and we argue that being visible and invisible requires work on the part of QLB patients in the context of institutionalized heteronormativity...

BACKGROUND AND OBJECTIVES: The quadratus lumborum block (QLB) is an abdominal truncal block, similar to transversus abdominis plane block (TAPB). However, the characteristics of QLB with regard to its duration and safety are not well known. The primary aim of this study was to determine the block duration and the cutaneous sensory block area. Our secondary analysis included assessment of the chronological change in arterial local anesthetic concentrations after QLB. METHODS: This study included 11 patients scheduled for laparoscopic ovarian surgery under general anesthesia...

BACKGROUND: Effective postoperative analgesia after caesarean section is important because it enables early ambulation and facilitates breast-feeding. Several case reports have shown that local anaesthetic injection around the quadratus lumborum muscle is effective in providing pain relief after various abdominal operations and in patients with chronic pain. The quadratus lumborum block (QLB) is performed in close proximity to the surface and uses a fascial compartment path to extend the distribution of local anaesthesia into the posterior abdominal wall and paravertebral space...

The Northeastern Qinghai-Tibetan Plateau (NQTP) contains many physical features that may have contributed to its rich biological diversity. We explored the systematics and genetic structures of the sand lizards Phrynocephalus putjatia, distributed across semi-deserts or rocky steppe habitats, and Phrynocephalus guinanensis, found only in sand dune habitats, from the NQTP using mitochondrial (ND2 and tRNAs) and nuclear (RAG-1) markers. Bayesian analyses revealed two main monophyletic mtDNA groups that separate populations of the Qinghai Lake Basin (QLB) from populations to the southeast of this basin (SEQL), but these did not correspond to the two morphological species...

Numerical simulations with previous formulations of the quantum lattice Boltzmann (QLB) scheme in three spatial dimensions showed significant lack of isotropy. In two or more spatial dimensions the QLB approach relies upon operator splitting to decompose the time evolution into a sequence of applications of the one-dimensional QLB scheme along coordinate axes. Each application must be accompanied by a rotation of the wave function into a basis of chiral eigenstates aligned along the relevant axis. The previously observed lack of isotropy was due to an inconsistency in the application of these rotations...

The phenomenon of Anderson localization in expanding one-dimensional Bose-Einstein condensates is investigated by numerically solving the Gross-Pitaevskii equation with a random speckle potential. To this purpose, a quantum lattice Boltzmann (QLB) method is used, and compared with a standard Crank-Nicolson scheme. The QLB simulations show evidence of Anderson localization even for relatively low-energy condensates, with a healing length as large as one-tenth of the Thomas-Fermi length. Moreover, very long-time simulations, lasting up to 15 000 optical confinement periods, indicate that the Anderson localization degrades in time, although at a very slow pace...

Fitting logistic regression models is challenging when their parameters are restricted. In this article, we first develop a quadratic lower-bound (QLB) algorithm for optimization with box or linear inequality constraints and derive the fastest QLB algorithm corresponding to the smallest global majorization matrix. The proposed QLB algorithm is particularly suited to problems to which EM-type algorithms are not applicable (e.g., logistic, multinomial logistic, and Cox's proportional hazards models) while it retains the same EM ascent property and thus assures the monotonic convergence...

The multidimensional formulation of the quantum lattice Boltzmann (qLB) scheme is extended to the case of nonlinear quantum wave equations. More specifically, imaginary-time formulations of the qLB scheme are developed and applied to the numerical computation of the ground state of the Gross-Pitaevskii equation in one and two spatial dimensions. The calculation is validated through detailed comparison with other numerical methods, as well as with analytical results based on the Thomas-Fermi approximation. The linear scaling of the time-step size with the spatial mesh spacing, a distinctive feature of the present quantum kinetic approach, is also numerically demonstrated...

The multidimensional formulation of the quantum lattice Boltzmann (QLB) scheme is validated against analytical solutions of the time-dependent nonrelativistic Schrödinger equation in two and three spatial dimensions. As a result, we demonstrate the viability of the quantum lattice Boltzmann scheme for the numerical solution of the time-dependent Schrödinger equation in multiple spatial dimensions. In addition, the links between the QLB scheme and sequential splitting methods for partial differential equations are also clarified...
