A Note on Balanced Incomplete Block Designs

The Annals of Mathematical Statistics, 1969
Summary: The author studies balanced incomplete block designs (BIBD) in which the blocks are not necessarily distinct. He proves the following Theorem. Let \(\mathcal D\) be a BIBD with parameters \(v,b,r,k,\lambda\). If \(s\) blocks of \(\mathcal D\) are identical and if \(r>\lambda\), then \(r/k=b/v\ge s\). The theorem implies the results of E.

Construction of Rotatable Designs Through Balanced Incomplete Block Designs

The Annals of Mathematical Statistics, 1962
Rotatable designs were introduced by Box and Hunter (1954, 1957) for the exploration of response surfaces. They constructed these designs through geometrical configurations and obtained several second order designs. Afterwards, Gardiner and others (1959) obtained some third order designs through the same technique for two and three factors and a third ...

Dual‐Interface‐Dominant Cathode Architectures Enabling Fast Sulfur Redox and Stable Interfaces in All‐Solid‐State Li‐S Batteries

Advanced Functional Materials, EarlyView.
An optimized carbon host nanostructure enables a dual‐interface‐dominant architecture in sulfur cathodes of solid‐state Li‐S batteries by selectively forming sulfur|carbon and sulfur|solid electrolyte interfaces. This tailored interfacial configuration accelerates sulfur redox kinetics by establishing enriched Li+/e– transport networks, while ...

Balanced Incomplete Block Designs and Tactical Configurations

The Annals of Mathematical Statistics, 1955
A balanced incomplete block design (BIB design) is an arrangement of $v$ varieties of treatments in $b$ blocks of $k$ distinct varieties each, so that each variety is contained in $r$ blocks and every pair of varieties is contained in $\lambda$ blocks. Various methods of constructing such designs are discussed in [2], and certain designs are listed in [

Exploring variation in parental worries about HPV vaccination: a latent-class analysis

Human Vaccines & Immunotherapeutics, 2019
Background. Prior research has identified diverse worries that parents have about HPV vaccination. We sought to understand how parents prioritize worries and to identify subgroups of parents according to shared patterns of worry. Methods.

Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

Advanced Functional Materials, EarlyView.
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

Voltage‐Gated Dedoping of n‐Doped Poly(benzodifurandione) as an Interfacial Protective Mechanism in Electrochromic Devices

Advanced Functional Materials, EarlyView.
Electrochromic polymer stability under overpotential is improved by inserting an ultrathin, transparent n‐doped poly(benzodifurandione) interlayer between indium tin oxide and a poly(3,4‐propylenedioxythiophene)‐based electrochromic polymer. The interlayer supports rapid switching at operating bias, then becomes resistive near +0.8 V to suppress excess

Bioengineered Lymphatic Vessels in Synthetic Matrices to Study Breast Cancer Cell Functions

Advanced Healthcare Materials, EarlyView.
Lymphatic vessels are involved in cancer metastasis. To study the interplay between metastasizing cancer cells and lymphatic vessels under highly reproducible conditions, advanced in vitro models are required. In this work, 3D lymphatic networks are formed in biomimetic hydrogels and their interactions with invasive and non‐invasive cancer cell‐lines ...
