On-site workshop investment problem: A novel mathematical approach and solution procedure

Author(s): Moradi N; Kayvanfar V; Baldacci R;

In real-world construction sites, On-Site Workshops (OSW) are installed to accelerate construction activities and facilitate the material handling process. These temporary OSWs are cost-effective, leading to decreasing the material handling cost and project makespan, which indicates their important role as a part of a construction project. However, consid ...

Decreased long-range temporal correlations in the resting-state functional magnetic resonance imaging blood-oxygen-level-dependent signal reflect motor sequence learning up to 2 weeks following training

Author(s): Jäger AP; Bailey A; Huntenburg JM; Tardif CL; Villringer A; Gauthier CJ; Nikulin V; Bazin PL; Steele CJ;

Decreased long-range temporal correlations (LRTC) in brain signals can be used to measure cognitive effort during task execution. Here, we examined how learning a motor sequence affects long-range temporal memory within resting-state functional magnetic resonance imaging signal. Using the Hurst e ...

Factors associated with change in moderate or severe symptoms of anxiety and depression in community-living adults and older adults during the COVID-19 pandemic

Author(s): Vasiliadis HM; Spagnolo J; Bartram M; Fleury MJ; Gouin JP; Grenier S; Roberge P; Shen-Tu G; Vena JE; Lamoureux-Lamarche C; Wang J;

Objectives: Few are the longitudinal studies on the changes in moderate or severe symptoms of anxiety or depression (MSS-ANXDEP) from before to during the COVID-19 pandemic in Canada. The aim was to study the change in MSS-ANXDEP and associated sociodemographic, economic, psychosocial, health beh ...

Effects of electron acceptors and donors on anaerobic biodegradation of PAHs in marine sediments

Author(s): Chen Q; Li Z; Chen Y; Liu M; Yang Q; Zhu B; Mu J; Feng L; Chen Z;

Polycyclic aromatic hydrocarbons (PAHs) are typical organic pollutants accumulated in the environment. PAHs' bioremediation in sediments can be promoted by adding electron acceptor (EA) and electron donor (ED). Bicarbonate and sulfate were chosen as two EAs, and acetate and lactate were selected as two EDs. Six groups of amendments were added into the ...

Effect of aquatic exercise versus standard care on paraspinal and gluteal muscles morphology in individuals with chronic low back pain: a randomized controlled trial protocol

Author(s): Rosenstein B; Montpetit C; Vaillancourt N; Dover G; Khalini-Mahani N; Weiss C; Papula LA; Melek A; Fortin M;

Background: Low back pain (LBP) is one of the most disabling diseases and a major health issue. Despite the evidence of a link between paraspinal and gluteal muscle dysfunction and LBP, it is unknown whether aquatic exercises can lead to improvements in paraspinal and gluteal muscle morphology an ...

Discovery of an adjuvant that resensitizes polymyxin B-resistant bacteria

Author(s): Mahdavi M; Findlay BL;

Infections caused by antibiotic-resistant bacteria are a major threat to health, increasing mortality rates and straining health systems worldwide. Adjuvants targeted to beta-lactamase function are able to resensitize bacteria to beta-lactam antibiotics, but there is comparatively little research into the use of adjuvants against other resistance phenotyp ...

Using 13C enriched acetate in isotope labelling incubation experiments: a note of caution

Author(s): Leone F; Imfeld A; Mirzaei Y; Gélinas Y;

Vapour-phase fumigation with HCl is routinely used to remove inorganic carbon in preparation for the measurement of the concentration and d13C value of organic carbon in a sample using elemental analysis coupled to an isotope ratio mass spectrometer. Acidification of the sample to be analyzed can lead to the loss of low molecular weight conjugate bases as ...

Evidence suggesting that reindeer mothers allonurse according to the direct reciprocity and generalized reciprocity decision rules

Author(s): Engelhardt SC; Weladji RB; Holand Ø; Røed KH; Nieminen M;

Allonursing is the nursing of the offspring of other mothers. Cooperation is an emergent property of evolved decision rules. Cooperation can be explained by at least three evolved decision rules: 1) direct reciprocity, i.e. help someone who previously helped you, 2) kin discrimination, i.e. preferentially direct help to kin than to non-kin, and 3) general ...

A longitudinal investigation of structural empowerment profiles among healthcare employees

Author(s): Cougot B; Gillet N; Morin AJS; Gauvin J; Ollierou F; Moret L; Tripodi D;

Purpose: Research on structural empowerment has typically adopted a variable-centered perspective, which is not ideal to study the combined effects of structural empowerment components. This person-centered investigation aims to enhance our knowledge about the configurations, or profiles, of healthcare employees' perceptions of the structural empowerm ...

What's control got to do with it? A systematic review of control beliefs in obsessive-compulsive disorder

Author(s): Sandstrom A; Krause S; Ouellet-Courtois C; Kelly-Turner K; Radomsky AS;

Current conceptualizations of control-related beliefs in Obsessive-Compulsive Disorder (OCD) have largely been limited to beliefs about the need to control thoughts. Although growing evidence supports the notion of considering broader control-related constructs in this disorder, there has been limited research aimed at integrating findings across studies, ...

The impact of lesion side on bilateral upper limb coordination after stroke

Author(s): Shih PC; Steele CJ; Hoepfel D; Muffel T; Villringer A; Sehm B;

Background: A stroke frequently results in impaired performance of activities of daily life. Many of these are highly dependent on effective coordination between the two arms. In the context of bimanual movements, cyclic rhythmical bilateral arm coordination patterns can be classified into two fundamental modes: in-phase (bilateral homologous muscles cont ...
