Anisotropic thermal expansion behavior of thin films of polymethylsilsesquioxane, a spin-on-glass dielectric for high-performance integrated circuits [PDF]

open access: yes, 2018
Thin films of poly(methylsilsesquioxane) (PMSSQ) are candidates for use as interdielectric layers in advanced semiconductor devices with multilayer structures.

Neurobehavioral Effects of Restricted and Unpredictable Environmental Enrichment in Rats

open access: yesFrontiers in Pharmacology, 2020
To study how motivational factors modulate experience-dependent neurobehavioral plasticity, we modify a protocol of environmental enrichment (EE) in rats.

Another new approach to the small Ree groups [PDF]

open access: yesArchiv der Mathematik, 2010
The Ree groups \(^2G_2(3^{2n+1})\) and \(^2F_4(2^{2n+1})\) were originally discovered by \textit{R. Ree} [in Am J. Math. 83, 432-462 (1961; Zbl 0104.24705) and Bull. Am. Math. Soc. 67, 115-116 (1961; Zbl 0104.24703), respectively]. They were constructed as the fixed points of certain automorphisms of order 2 of Chevalley groups \(G_2(3^{2n+1})\) and ...

Synthesis and blue light-emitting characteristic of rod-like poly(4,4 '-biphenylene pyromellitimide) with furyl side groups [PDF]

open access: yes, 1999
A new 2,2'-bis(furyl)benzidine (FurylBZ) with a well-defined conjugation length was synthesized, and its polyimide was prepared through thermal imidization of the poly(amide acid) obtained from the polymerization with pyromellitic dianhydride ...

Suzuki–Ree groups and Tits mixed groups over rings [PDF]

open access: yesCommunications in Algebra, 2019
It is shown that Suzuki-Ree groups can be easily defined by means of comparing two fundamental representations of the ambient Chevalley group in characteristic 2 or 3. This eliminates the distinction between the Suzuki-Ree groups over perfect and imperfect fields and gives a natural definition for the analogues of such groups over commutative rings. As

Totally chiral maps and hypermaps of small genus [PDF]

open access: yes, 2009
An orientably regular hypermap is totally chiral if it and its mirror image have no non-trivial common quotients. We classify the totally chiral hypermaps of genus up to 1001, and prove that the least genus of any totally chiral hypermap is 211, attained

Leptin resistance in patients with chronic schizophrenia

open access: yesPsychiatria i Psychologia Kliniczna, 2019
Aim: Leptin is produced by the adipose tissue and reduces body weight by decreasing appetite and increasing metabolism. Patients treated with antipsychotics often have treatment-induced weight-gain, leading to other metabolic complications.

Resting and exercise metabolic characteristics in obese children with insulin resistance

open access: yesFrontiers in Physiology, 2022
Purpose: This study aimed to explore the characteristics of resting energy expenditure (REE) and lipid metabolism during incremental load exercise in obese children and adolescents with insulin resistance (IR) to provide evidence for exercise ...
