A Geometric Characterization of Steady Laminar Flow

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the steady states of the Euler equations on the periodic channel or annulus. We show that if these flows are laminar (layered by closed non‐contractible streamlines which foliate the domain), then they must be either parallel or circular flows.

Compact Manifolds With Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has a uniformly almost nilpotent fundamental group. Leftover questions and conjectures, have asked if in this context the fundamental group is actually uniformly almost abelian. The main goal of this work is to construct examples (Mk9,gk)$(

An Intensity Measure‐Based Methodology for Ground Motion Orientation in Seismic Structural Assessment

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...

Treatment With the Shaker Head‐Lift Exercise in Head and Neck Cancer Patients With Radiation‐Induced Dysphagia: 12‐Month Results on Swallowing Function From a Randomized, Controlled Trial

Head &Neck, EarlyView.
ABSTRACT Background Dysphagia is a common side‐effect after radiotherapy in head and neck cancer patients. This randomized study aimed to evaluate the effect of the shaker head‐lift exercise (HLE) after 12 months with flexible endoscopic evaluation of swallowing (FEES). Methods Patients were randomly assigned to the intervention (n = 30) or the control

Spatiotemporal dynamics of brain function network during proprioception rehabilitation after anterior cruciate ligament reconstruction: A randomized trial

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
The improvement of proprioceptive function after ACLR is related to the optimization of spatiotemporal dynamics of SM, CC, DM, CB and VI functional networks. Rehabilitation optimization can incorporate visual–cognitive dual‐task exercises. Abstract Purpose In this study, we aimed to examine the dynamic functional network connectivity (dFNC) patterns ...

Similar dynamic tibiofemoral movements during jump‐landing and walking but distinct hamstrings strength across ACL reconstruction autograft types at mid‐term follow‐up

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Dynamic tibiofemoral movements following anterior cruciate ligament reconstruction (ACLR) with quadriceps tendon (QT) autografts have not yet been compared to other autografts. We aimed to compare dynamic anterior tibial translation (ATTd) and internal tibial rotation (ITRd) during jump‐landing and walking among patients with QT, bone ...

Impact of hamstring versus quadriceps tendon graft on thigh muscle strength and surface electromyography activity after anterior cruciate ligament reconstruction

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare quadriceps tendon (QT) and hamstring tendon (HT) autografts regarding isometric thigh muscle strength, surface electromyography (sEMG) activity and clinical outcomes following anterior cruciate ligament reconstruction (ACLR).

Superior patient‐reported clinical outcomes after patient‐individual total knee arthroplasty compared with off‐the‐shelf robotic‐assisted total knee arthroplasty in valgus knee phenotypes

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare early patient‐reported clinical outcomes of patient‐individual total knee arthroplasty (TKA) with individualized trochlear design versus robotic‐assisted TKA using off‐the‐shelf implants in patients with valgus knee phenotypes and pronounced femoral valgus (lateral distal femoral angle [LDFA] < 85°) at 3 and 12 months ...

Nutrition and rehabilitation after anterior cruciate ligament reconstruction: A systematic review

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose As the impact of nutrition on rehabilitation and return to sport (RTS) after ACL reconstruction (ACLR) remains largely unexplored, this review aimed to review the current evidence on the role of nutrition in rehabilitation outcomes for ACLR patients, with as ultimate goal a safer and more successful RTS.

Biologic gracilis augmentation with iliotibial band enhances recovery and lowers complications in ACL reconstruction compared with hamstring plus lateral tenodesis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To compare the iliotibial band autograft biologically augmented with gracilis (ITBAG) technique with a hamstring tendon autograft combined with extra‐articular lateral tenodesis using fascia lata (HT‐LET), in terms of (1) return‐to‐sport rates, (2) patient‐reported functional outcomes and (3) complication rates.
