Experimental Research on Damping Effect of Double-Layer Tuned Mass Damper for High-Rise Structure

open access: yesShock and Vibration, 2021
A double-layer tuned mass damper (DTMD) has advantages of wide damping frequency band and strong robustness. At present, there is a lack of seismic design methods for high-rise structures based on DTMDs.

Locomotion Index and Retinal Thickness of the Eye Anguilla bicolor bicolor in its Developmental Stage

open access: yesJurnal Biota, 2023
When migrating to the deep sea, the eye of the eel which functions for locomotion will adapt to the deep environment. This study is the first study to identify the locomotion index and the retinal structure at the stage glass eel, elver, yellow, and ...

STRUCTURAL HOMOPHILY [PDF]

open access: yesInternational Economic Review, 2015
Homophily, or the fact that similar individuals tend to interact with each other, is a prominent feature of economic and social networks. I show that the equilibrium structure of homophily has empirical power. I build a strategic model of network formation, which produces a unique equilibrium network.

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.

On how the mechanochemical and co-precipitation synthesis method changes the sensitivity and operating range of the Ba2Mg1-xEuxWO6 optical thermometer

open access: yesScientific Reports, 2021
The suitability of Ba2MgWO6 (BMW) double perovskite doped with Eu3+ for the construction of an optical thermometer was tested. It has been shown that by controlling the conditions of BMW synthesis, the sensitivity of the optical thermometer and the ...

Telomerase structure

open access: yesCurrent Opinion in Structural Biology, 2014
The telomerase reverse transcriptase has an essential role in telomere maintenance and in cancer biology. Progress during the last year has revealed the three-dimensional architecture of both human and ciliate telomerase at about 25Å resolution, obtained using single particle electron microscopy (EM).

Structured data structures [PDF]

open access: yesCommunications of the ACM, 1974
Programming systems which permit arbitrary linked list structures enable the user to create complicated structures without sufficient protection. Deletions can result in unreachable data elements, and there is no guarantee that additions will be performed properly.

Feasibility and Safety of High‐Dose Proton Re‐Irradiation in Recurrent Pediatric Central Nervous System Tumors: A Single‐Institution Retrospective Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with

Connection structures.

open access: yesNotre Dame Journal of Formal Logic, 1991
The authors investigate a calculus of individuals based on a primitive notion of connectedness. They show that their system of axioms leads to complete orthocomplemented lattices whereas the extension of their system to the Clarke system leads to complete atomless Boolean algebras [see also \textit{B. Clarke}, ibid. 26, 61-75 (1985; Zbl 0597.03005)].
