Identification of Piecewise Linear Models of Complex Dynamical Systems

open access: yes, 2011
The paper addresses the realization and identification problem or a subclass of piecewise-affine hybrid systems. The paper provides necessary and sufficient conditions for existence of a realization, a characterization of minimality, and an ...

Aquatic Hemiptera of Wisconsin [PDF]

open access: yes, 2017
About 59,000 aquatic Hemiptera were collected in Wisconsin, most of them in the last 15 years. These include three species of Belostomatidae, 48 species of Corixidae, one species of Naucoridae, four species of Nepidae, nine species of Notonectidae, and ...

Toxin–antitoxin systems [PDF]

open access: yesMobile Genetic Elements, 2013
Toxin-antitoxin (TA) systems are small genetic elements composed of a toxin gene and its cognate antitoxin. The toxins of all known TA systems are proteins while the antitoxins are either proteins or non-coding RNAs. Based on the molecular nature of the antitoxin and its mode of interaction with the toxin the TA modules are currently grouped into five ...

Leveraging a Relationship with Biology to Expand a Relationship with Physics

open access: yes, 2015
This work examines how experiences in one disciplinary domain (biology) can impact the relationship a student builds with another domain (physics).

A domain ontology for the non-coding RNA field [PDF]

open access: yes, 2015
Identification of non-coding RNAs (ncRNAs) has been significantly enhanced due to the rapid advancement in sequencing technologies. On the other hand, semantic annotation of ncRNA data lag behind their identification, and there is a great need to ...

Unambiguous identification of fungi: where do we stand and how accurate and precise is fungal DNA barcoding?

open access: yesIMA Fungus, 2020
True fungi (Fungi) and fungus-like organisms (e.g. Mycetozoa, Oomycota) constitute the second largest group of organisms based on global richness estimates, with around 3 million predicted species.

Ultrasonographic and Three-Dimensional Analyses at the Glabella and Radix of the Nose for Botulinum Neurotoxin Injection Procedures into the Procerus Muscle

open access: yesToxins, 2019
Botulinum neurotoxin (BoNT) injections are widely used for facial rejuvenation procedures, and the procerus muscle is a major target in cases of glabellar transverse lines or rhytids.

Novel Anatomical Proposal for Botulinum Neurotoxin Injection Targeting Lateral Canthal Rhytids

open access: yesToxins, 2022
Botulinum neurotoxin injections near the lateral canthal rhytids are commonly used in cosmetic settings; however, there is a lack of thorough anatomical knowledge, and an effective way to treat them with accumulating knowledge is needed.

A new type of identification problems: optimizing the fractional order in a nonlocal evolution equation [PDF]

open access: yes, 2016
In this paper, we consider a rather general linear evolution equation of fractional type, namely a diffusion type problem in which the diffusion operator is the $s$th power of a positive definite operator having a discrete spectrum in $\R^+$.
