Orientable and Negative Orientable Sequences

Discrete Applied Mathematics
Analogously to de Bruijn sequences, orientable sequences have application in automatic position-location applications and, until recently, studies of these sequences focused on the binary case. In recent work by Alhakim et al., a range of methods of construction were described for orientable sequences over arbitrary finite alphabets; some of these ...

Orientation

Curationis, 1985
Oriëntasie van ’n nuwe werknemer is noodsaaklik om angs te verlig en om horn/ haar van die inligting wat nodig is vir bevredigende werksverrigting te voorsien. Orientasieprogramme moet aangepas word by die spesifieke behoeftes van elke nuwe werknemer. Daar kan onderskei word tussen makro- en mikro-oriëntasie.

The Kaʿba Orientations

American Journal of Islam and Society, 2020
The Kaʿba has central role in Islamic culture. It orients Muslims both physically and perceptually in their daily lives and worship. Recognising its obscurity in extant scholarship on Islamic art and architecture, Simon O'Meara seeks to understand how ...

Inpatient Exposure, Confidence, and Knowledge in Pediatric Hematology/Oncology: Evaluating General Pediatric Residents During 2025 ACGME Curriculum Change

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background General pediatricians often evaluate hematologic and oncologic presentations before subspecialty consultation, yet the 2025 Accreditation Council for Graduate Medical Education (ACGME) pediatric requirements reduce inpatient pediatric hematology/oncology (PHO) time, raising questions about resident readiness.

How do orientations matter in early childhood education? Children, choices and gendering processes

Journal of Early Childhood Education Research
This paper explores children’s “own” choices in relation to gendering in ECE. Specifically, it problematizes what is often referred to as children’s “own” choices within child-centred pedagogies and emphasises how children’s choices are effects of ...

On the oriented chromatic index of oriented graphs [PDF]

Journal of Graph Theory, 2007
AbstractA homomorphism from an oriented graph G to an oriented graph H is a mapping $\varphi$ from the set of vertices of G to the set of vertices of H such that $\buildrel {\longrightarrow}\over {\varphi (u) \varphi (v)}$ is an arc in H whenever $\buildrel {\longrightarrow}\over {uv}$ is an arc in G. The oriented chromatic index of an oriented graph G

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
