无级变速谐波传动原理与传动比计算

open access: yesJixie chuandong, 2006
By making relative movement between the flexible spline and rigid spline,either of them has a taper hole or taper surface,this results in the perimeter difference 2((R-r)of flexible spline and rigid spline continuous variation, then realizes continuous ...

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

P-spline anova-type interaction models for spatio-temporal smoothing [PDF]

open access: yes, 2009
In recent years, spatial and spatio-temporal modelling have become an important area of research in many fields (epidemiology, environmental studies, disease mapping, ...).

Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

open access: yesThe Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

Prophylactic Enoxaparin Reduces Symptomatic Venous Thromboembolism Compared With No Chemoprophylaxis Within 95 Days After Knee Arthroscopy

open access: yesArthroscopy, EarlyView.
Purpose To investigate whether prophylactic use of low‐molecular‐weight heparin (enoxaparin) after knee arthroscopy reduces the incidence of symptomatic venous thromboembolism (VTE) compared with no postoperative pharmacological prophylaxis. Methods We conducted a population‐based cohort study using linked national insurance and hospital data from ...

Improved orders of approximation derived from interpolatory cubic splines [PDF]

open access: yes, 1978
Let s be a cubic spline, with equally spaced knots on [a,b], interpolating a given function y at the knots. The parameters which determine s are used to construct a piecewise defined polynomial P of degree four.

Longitudinal Modulation of the Gut Microbiome and Growth Performance by Phytochemicals as Antibiotic Alternatives in Swine Production

open access: yesAnimal Research and One Health, EarlyView.
We conducted a longitudinal trial across nursery, growing, and finishing phases, showing that phytochemical supplementation as a potential antibiotic alternative reduced potential pathogens and promoted beneficial Lactobacillus amylovorus in the nursery phase, and enriched amino acid and carbohydrate metabolism pathways (prediction) during finishing ...

The information content in bond model residuals: an empirical study on the Belgian bond market. [PDF]

open access: yes
We estimate daily Vasicek, CIR, and spline models on Belgian data and compare the trading profits that can be made on the basis of the model residuals. Abnormal returns are negatively related to lagged mispricing.

Challenges and Opportunities in Multi‐Method Integrated Geophysical Prospection of Buried Building Remains at the Sanctuary of Olympia

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Ancient Olympia was one of the most important sanctuaries and the venue for the Olympic Games in Greek and Roman times. Its remains are located in the Olympia Terrace (Peloponnese, Greece) at the present‐day confluence of the rivers Alpheios and Kladeos at the base of Mount Kronos.

A class of piecewise cubic interpolatory polynomials [PDF]

open access: yes, 1979
A new class of C1 piecewise—cubic interpolatory polynomials is defined, by generalizing the definition of cubic X-splines given recently by Clenshaw and Negus (1978).
