The international food unit: a new measurement aid that can improve portion size estimation

International Journal of Behavioral Nutrition and Physical Activity, 2017
Background Portion size education tools, aids and interventions can be effective in helping prevent weight gain. However consumers have difficulties in estimating food portion sizes and are confused by inconsistencies in measurement units and ...

Bioinspired Co‐Assembly Enables Multiscale Architected Hydrogels for 3D Printing With Integrated Antibacterial and Bioactive Functions

Advanced Functional Materials, EarlyView.
A multicomponent supramolecular hydrogel integrating cell‐adhesive and antibacterial peptides within an alginate‐cellulose nanofibril matrix is developed. Peptide co‐assembly simultaneously strengthens the hydrogel network, improves extrusion printability, and imparts cell‐adhesive and antibacterial functions, offering a versatile platform for ...

Higher-dimensional Dedekind sums and their bounds arising from the discrete diagonal of the n-cube [PDF]

, 2006
Higher-dimensional Dedekind sums are defined as a generalization of a recent one-dimensional probability model of Dilcher and Girstmair to a d-dimensional cube.

Some problems and algorithms related to the weight order relation on the n-dimensional Boolean cube [PDF]

Discrete Mathematics, Algorithms and Applications, 2020
The problem “Given a Boolean function [Formula: see text] of [Formula: see text] variables by its truth table vector. Find (if exists) a vector [Formula: see text] of maximal (or minimal) weight, such that [Formula: see text].” is considered here. It is closely related to the problem of computing the algebraic degree of Boolean functions which is an ...

Melanin's Role in Balancing Mechanical Strength and Reproductive Output in Environmentally Stressed Fungal Spores

Advanced Functional Materials, EarlyView.
Melanin content directly controls fungal spore mechanical properties, with pigmented spores achieving rupture forces two orders of magnitude higher than hyaline spores. Environmental stress drives this quantity‐quality tradeoff; stressed species invest energy in melanin‐reinforced, mechanically superior thick‐walled, super‐hydrophobic spores, while ...

Minimum neighbourhood in a generalized cube

, 2006
Generalized cubes are a subclass of hypercube-like networks, which include some hypercube variants as special cases. Let theta(G)(k) denote the minimum number of nodes adjacent to a set of k vertices of a graph G.

Crystal structures of two CuII compounds: catena-poly[[chloridocopper(II)]-μ-N-[ethoxy(pyridin-2-yl)methylidene]-N′-[oxido(pyridin-3-yl)methylidene]hydrazine-κ4N,N′,O:N′′] and di-μ-chlorido-1:4κ2Cl:Cl-2:3κ2Cl:Cl-dichlorido-2κCl,4κCl-bis[μ3-ethoxy(pyridin-2-yl)methanolato-1:2:3κ3O:N,O:O;1:3:4κ3O:O:N,O]bis[μ2-ethoxy(pyridin-2-yl)methanolato-1:2κ3N,O:O;3:4κ3N,O:O]tetracopper(II)

Acta Crystallographica Section E: Crystallographic Communications, 2019
Two CuII complexes [Cu(C14H13N4O2)Cl]n, I, and [Cu4(C8H10NO2)4Cl4]n, II, have been synthesized. In the structure of the mononuclear complex I, each ligand is coordinated to two metal centers.

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

Advanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.

The View-Obstruction Problem forn-Dimensional Cubes

Journal of Number Theory, 1999
The view-obstruction problem for the \(n\)-dimensional cube is equivalent to the conjecture that for any \(n\) positive integers \(v_1,\dots, v_n\) there is a real number \(x\) with \[ \| v_ix\|\geq (n+1)^{-1}, \quad i=1,\dots, n, \] where \(\| y\|\) denotes the distance from \(y\) to the next integer. This conjecture has been previously solved for \(n=

In Situ Magnetic Ordering and Microfabrication of Liquid Crystal Networks with Discretized Alignment

Advanced Functional Materials, EarlyView.
Miniaturizing liquid crystal network actuators typically demands costly laser writing or digital light processing. A low‐cost photolithography platform couples rotating photomasks with a Halbach magnetic array to discretize in‐plane molecular alignment down to 50 µm, producing programmable, light‐responsive grippers, checkerboards, and origami‐inspired
