A Protocol to Systematic Radiographic Assessment of Primary Total Knee Arthroplasty.

Orthop Res Rev 2021 17;13:95-106. Epub 2021 Jul 17.

Orthopaedic and Traumatology Department, Assiut University Hospital, Assiut, Egypt.

Although total knee arthroplasty (TKA) is considered one of the most successful procedures, however, a subset of patients are unsatisfied with the results, even with the introduction of new technologies and implant designs. Radiological assessment of TKA is still considered the most prevalent imaging modality for evaluating the knee joint pre-and postoperatively. Assessment of various angles and indices which could be measured in different radiographic views of the knee provides valuable information about the alignment of the entire limb and the individual prosthetic components, more so in the light of recent nuanced concepts of technique, alignment, and balance.

Measuring Shared Electrons in Extended Molecular Systems: Covalent Bonds from Plane-Wave Representation of Wave Function.

Molecules 2021 Jul 1;26(13). Epub 2021 Jul 1.

Department of Mathematics, Computer Science, and Physics, University of Udine, Via Delle Scienze 206, I-33100 Udine, Italy.

In the study of materials and macromolecules by first-principle methods, the bond order is a useful tool to represent molecules, bulk materials and interfaces in terms of simple chemical concepts. Despite the availability of several methods to compute the bond order, most applications have been limited to small systems because a high spatial resolution of the wave function and an all-electron representation of the electron density are typically required. Both limitations are critical for large-scale atomistic calculations, even within approximate density-functional theory (DFT) approaches. Read More

Disentangling the Psycholinguistic Loci of Anomia with Cognitive Psychometric Models.

Grant M Walker

Semin Speech Lang 2021 Jun 14;42(3):256-274. Epub 2021 Jul 14.

Department of Cognitive Sciences, University of California, Irvine, California.

This article reviews advanced statistical techniques for measuring impairments in object naming, particularly in the context of stroke-induced aphasia. Traditional testing strategies can be challenged by the multifaceted nature of impairments that arise due to the complex relationships between localized brain damage and disruption to the cognitive processes required for successful object naming. Cognitive psychometric models can combine response-type analysis with item-response theory to yield accurate estimates of multiple abilities using data collected from a single task. Read More

Simultaneous ambient pressure x-ray photoelectron spectroscopy and grazing incidence x-ray scattering in gas environments.

Rev Sci Instrum 2021 Apr;92(4):044102

Advanced Light Source, Lawrence Berkeley National Laboratory, Berkeley, California 94720, USA.

We have developed an experimental system to simultaneously measure surface structure, morphology, composition, chemical state, and chemical activity for samples in gas phase environments. This is accomplished by simultaneously measuring x-ray photoelectron spectroscopy (XPS) and grazing incidence x-ray scattering in gas pressures as high as the multi-Torr regime while also recording mass spectrometry. Scattering patterns reflect near-surface sample structures from the nano-scale to the meso-scale, and the grazing incidence geometry provides tunable depth sensitivity of structural measurements.

Moving from physical survival to psychologic recovery: a qualitative study of survivor perspectives on long-term outcome after sudden cardiac arrest.

Resusc Plus 2021 Mar 31;5:100055. Epub 2020 Dec 31.

Sunnybrook Health Sciences Centre, Toronto, Ontario, Canada.

Background: Over 400,000 adults suffer out-of-hospital cardiac arrests (OHCA) each year in North America. Despite a very high mortality rate, even 10% survival means that a minimum of 3500 people return to their lives and their families. However, their experience of living and their health-related quality of life after such a life-changing event are quite variable, much more complex than just having lived or died, and should not be reduced to crude measures of neurological functioning.

Introducing the EPP house (topological space) method to solve MRP problems.

PLoS One 2021 22;16(6):e0253330. Epub 2021 Jun 22.

Management Campus, Széchenyi István University, Hungary, Győr, Hungary.

The problem of product and process planning analysed so far is how we can take advantage of our strategy in planning. Among the principles of manufacturing and service management concepts is that after planning demand, planning transformation is one of the key steps of integrated efficiency; it makes it possible to save costs that are not value adding and are not necessary from the customer's point of view. Currently, the methods of material requirements and capacity planning can be seen as classic solutions that are based on dependency relations between different resources, which can be dynamic in space and time.

Minimal Organizational Requirements for the Ascription of Animal Personality to Social Groups.

Front Psychol 2020 29;11:601937. Epub 2021 Apr 29.

National Institute of Science and Technology in Interdisciplinary and Transdisciplinary Studies in Ecology and Evolution (INCT IN-TREE), Federal University of Bahia, Salvador, Brazil.

Recently, psychological phenomena have been expanded to new domains, crisscrossing boundaries of organizational levels, with the emergence of areas such as social personality and ecosystem learning. In this contribution, we analyze the ascription of an individual-based concept (personality) to the social level. Although justified boundary crossings can boost new approaches and applications, the indiscriminate misuse of concepts refrains the growth of scientific areas. Read More
