Authors: Lord Linda K. , Ingwersen Walter , Gray Janet L. , Wintz David J. 
Published: July 2009

Abstract
Objective—To characterize animals with microchips entering animal shelters and the process used to find owners.
Design—Cross-sectional study.
Animals—7,704 microchipped animals entering 53 animal shelters between August 2007 and March 2008.
Procedures—Data for animals with microchips were recorded by participating animal shelters and reported monthly.
Results—Of 7,704 animals, strays accounted for slightly more than half (4,083 [53.0%]), with the remainder classified as owner-relinquished animals (3,225 [41.9%]) and other (396 [5.1%]). Of 3,425 stray animals for which animal shelters reported that the owner was found, a higher percentage of dog owners (2,191/2,956 [74.1%]) than cat owners (298/469 [63.5%]) was found. For 876 animals for which the owners could not be found, the main reasons were incorrect or disconnected telephone number (310 [35.4%]), owner did not return telephone calls or respond to a letter (213 [24.3%]), and animal was registered to another group (151 [17.2%]). Of 1,943 animals for which animal shelters contacted a microchip registry, 1,129 (58.1%) were registered in the database. Purebred neutered dogs whose owner information was in the shelter database registry or microchip registry had a higher likelihood that the owners would be found.
Conclusions and Clinical Relevance—The high rate for return of microchipped dogs and cats to their owners supported microchipping as a valuable permanent pet identification modality; however, issues related to registration undermined its overall potential. Bundling of microchip implantation and registration, point-of-implantation data registration, use of annual compliance and update reminders, and providing access to all registries are potential solutions.

Abstract
Objective—To determine neurologic indications associated with abnormal results for computed tomography (CT) imaging of the head of horses affected by neurologic disorders.
Design—Retrospective case series.
Animals—57 horses.
Procedures—Signalment, history, clinical abnormalities, and clinicopathologic findings were obtained from medical records of horses examined because of neurologic disorders, and precontrast and postcontrast CT images of the head were reviewed. Data were analyzed by use of univariate and multivariate logistic regression.
Results—For a horse with abnormal mentation, odds of having abnormal results for CT imaging of the head was 30 times (95% confidence interval [CI], 2.36 to 374.63) the odds for a similar horse without abnormal mentation. For a horse with cranial nerve deficits, odds of having abnormal results for CT imaging of the head was 11 times (95% CI, 1.00 to 127.96) the odds for a similar horse without cranial nerve deficits. For a horse with seizure-like activity, odds of having abnormal results for CT imaging of the head was 0.05 times (95% CI, 0 to 0.90) the odds for a similar horse without seizures.
Conclusions and Clinical Relevance—These results suggested that alterations in consciousness and cranial nerve deficits were strong predictors of abnormal CT findings for the head of affected horses. Thus, CT can be a useful complementary diagnostic test in horses with these neurologic deficits. In contrast, alternative diagnostic tests (eg, electroencephalography and magnetic resonance imaging) should be considered in horses with seizure-like activity that do not have head trauma or cranial nerve deficits.
Pneumocephalus secondary to removal of an osteoma from the paranasal sinuses of a horse
Authors: Ragle Claude A. , de Mira Monica C. , Pearson Lisa K. , Coelho Joana C. 
Published: July 2009

Abstract
Case Description—A 2-year-old Quarter Horse was evaluated because of a progressive left-sided facial deformity and unilateral nasal and ocular discharge.
Clinical Findings—Physical examination revealed convexity of the left frontonasal region, left-sided nasal and ocular discharge, and decreased air flow through the left nares. Radiography and computed tomography revealed an extensively mineralized mass occupying most of the left paranasal sinuses.
Treatment and Outcome—The mass was surgically debulked, but complete removal was precluded because the mass was tightly adhered to the frontal and maxillary bones. Results of histologic examination of the mass were consistent with a diagnosis of osteoma. The horse developed transient pyrexia and colic following surgery, and postoperative radiography revealed gas opacities in the lateral ventricles of the brain, consistent with iatrogenic pneumocephalus. However, the horse did not develop any neurologic signs and was performing normally 2 years after surgery.
Clinical Relevance—Findings reinforce concerns that paranasal sinus surgery in horses can be associated with intracranial complications such as pneumocephalus. In horses with a mass involving the paranasal sinuses, computed tomography may be helpful in determining the boundaries of the mass and formulating a surgical treatment plan.

Authors: Johnson Shawn P. , Venn-Watson Stephanie K. , Cassle Stephen E. , Smith Cynthia R. , Jensen Eric D. , Ridgway Sam H. 
Published: July 2009

Abstract
Case Description—3 adult (24- to 43-year-old) Atlantic bottlenose dolphins (Tursiops truncatus) with chronic episodic malaise and inappetence associated with high serum aminotransferase (alanine aminotransferase and aspartate aminotransferase) activities, high serum iron concentration, and serum transferrin saturation > 80% were evaluated.
Clinical Findings—Results of histologic examination of liver biopsy specimens revealed hemosiderosis in all 3 dolphins. Except for chronic lymphocytosis in 1 dolphin, results of extensive diagnostic testing revealed no other abnormalities. For each dolphin, a diagnosis of iron overload of unknown origin was made.
Treatment and Outcome—Phlebotomy treatment was implemented to reduce body stores of iron. Each phlebotomy procedure removed 7% to 17% (1 to 3 L) of estimated blood volume. Treatment consisted of an induction phase of weekly phlebotomy procedures for 22 to 30 weeks, which was complete when serum iron concentration and aminotransferase activities were within reference ranges and serum transferrin saturation was ≤ 20% or Hct was ≤ 30%. Total amount of iron removed from each dolphin was 53 to 111 mg/kg (24.1 to 50.5 mg/lb) of body weight. One dolphin required maintenance procedures at 8- to 12-week intervals when high serum iron concentration was detected.
Clinical Relevance—Although the cause of the iron overload and high serum aminotransferase activities remained unknown, phlebotomy treatment successfully resolved the clinicopathologic abnormalities, supporting a role of iron overload in the hepatopathy of the 3 dolphins.

Analysis of nanoindentation curves in the case of bulk amorphous polymers
Authors: Beyaoui Moez , Mazeran Pierre-Emmanuel , Arvieu Marie-Florence , Bigerelle Maxence , Guigon Michèle 
Published: July 2009

Abstract
Load versus displacement curves obtained from nanoindentation experiments on polymers are particularly difficult to analyze due to their complex mechanical and especially time-dependent behavior. The indentation curves obtained on two amorphous polymers (polycarbonate (PC) and polymethyl methacrylate (PMMA)) show an increase in the indentation depth during load hold time. A non-linear time-dependent model shows that this phenomenon could be decomposed in a first part due to a viscoelastic response and a second part assigned both to a viscoelastic and a viscoplastic response. If the first part is not achieved, the values of the elastic modulus computed using the Oliver and Pharr method are abnormally high. If it is achieved, the beginning of the unloading curve presents an abnormality that is linked to the increase in indentation depth during hold load time. Nevertheless, if the load hold time is high enough and if the contact stiffness is calculated from the initial slope of the power fit of the unloading curve, the values of the elastic modulus computed using the Oliver and Pharr method are close to those obtained by tensile tests.
Mutual consistency of hardness testing at micro- and nanometer scales
Authors: Useinov Alexey , Gogolinskiy Kirill , Reshetov Vladimir 
Published: July 2009

Abstract
To a considerable degree hardness is an empirical value which depends on many details involved in the measuring process. In the present work, hardness values were measured in the depth range 2 – 800 nm using microhardness, nanoindentation and scratch hardness tests on fused silica, steel and sapphire. It is shown that overestimation of hardness values for steel and sapphire with the nanoindentation method can be directly related to the relative height of pile-ups observed on the topography image of the indentation imprint. It is also shown that the scratch hardness test is a promising technique for nanoscaled hardness measurements.

Authors: Krause Christian , Springer Ronald , Gershteyn Gregory , Dudzinski Wlodzimierz , Bach Friedrich-Wilhelm 
Published: July 2009

Abstract
In the present work, investigations of the microstructural changes were carried out during hardening and tempering of 42CrMo4 (1.7225) steel. Using transmission electron microscopy, the hardened state was examined initially. Following this, the material was incrementally heated in a heated specimen holder to 580 °C. Diffraction patterns were recorded at regular intervals in order to analyse and document the changes from a martensitic structure to a ferritic structure. The characteristic tempering stages were identified for the material and assigned to a temperature range. Moreover, thermal activated diffusion processes were detected above 500 °C.

Published: July 2009

Abstract
The enthalpies of mixing in liquid Ag – Ca, Ag – Eu and Ag – Yb alloys were measured by isoperibolic calorimetry at 1300 K. The experimental data were used to calculate the mixing enthalpies within the total composition region. The results of the investigation show exothermic effect of alloy formation. The minimum integral enthalpies of mixing are – 23.5 ± 1.0 kJ · mol – 1 (the Ag – Ca system); –16.5 ± 1.5 kJ · mol – 1 (the Ag – Eu system) and – 21.5 ± 1.9 kJ · mol – 1 (the Ag – Yb system) and are located in the silver-rich composition regions.
Dilatometry revealing Si precipitation in Al–Si-alloys
Authors: Lasagni Fernando , Dumont Myriam , Salamida Côme , Acuña Jorge Antonio , Degischer H. Peter 
Published: July 2009

Abstract
The precipitation kinetics of Si after different thermal treatments in AlSi-alloys have been studied by means of isothermal calorimetry, differential scanning calorimetry and dilatometry tests. The measured exothermic and endothermic effects produced by the precipitation and dissolution of Si are correlated with the increase and reduction in the coefficient of thermal expansion CTE(T), respectively. The deviation of the CTE(T) of the studied AlSi1.1 – 1.7 alloys with respect to pure Al correspond to the volume fraction of precipitating Si according to thermodynamic solubility limits. Two different kinetics in the growth of Si precipitates are distinguished: while Si precipitates in the range of 200 – 300 °C during heating of solution quenched samples supersaturated with vacancies, retardation into the temperature range of 300 – 420 °C is observed in samples slowly cooled after solution treatment. The presence of the eutectic Si increases the quench sensitivity of the precipitation kinetics of Si as observed in CTE(T) curves. The ripening of the eutectic Si during prolonged solution treatment retards the Si precipitation slightly.
Distributed adaptive parameter estimation over weakly connected digraphs using a relaxed excitation condition
Authors: Garg Tushar , Basu Roy Sayan 
Published: April 2024

SummaryIn this article, a novel distributed adaptive parameter estimation (DAPE) algorithm is proposed for an multi‐agent system over weakly connected digraph networks, where parameter convergence is ensured under a newly coined relaxed excitation condition, called generalized cooperative initial excitation (gC‐IE). This is in contrast to the past literature, where such DAPE algorithms demand cooperative persistent of excitation (C‐PE) and generalized cooperative persistent of excitation (gC‐PE) for strongly connected digraph, and weakly connected digraph networks, respectively, for parameter convergence. The gC‐PE and C‐PE conditions are restrictive in the sense that they require the richness/excitation of information over the entire time‐span of the signal/data, unlike gC‐IE condition where excitation is needed only in the initial time‐span. The newly coined gC‐IE condition is an extension of cooperative initial excitation (C‐IE) condition. While the C‐IE condition is applicable to a strongly connected digraph, the newly proposed gC‐IE condition extends the concept to weakly connected digraph. The proposed algorithm utilizes a novel set of weighted integrator dynamics, which omits the requirement of computationally involved multiples switching mechanisms in past literature, while still ensuring parameter convergence. The proposed algorithm provides global exponential stability of origin of the parameter estimation error dynamics under gC‐IE condition. Furthermore, robustness to unmodeled disturbance is also established in the form of input‐to‐state stability. Simulation results validate the efficacy of the proposed algorithm in contrast to the gC‐PE based algorithm.

AbstractGermanium‐based monochalcogenides (i.e., GeS and GeSe) with desirable properties are promising candidates for the development of next‐generation optoelectronic devices. However, they are still stuck with challenges, such as relatively fixed electronic band structure, unconfigurable optoelectronic characteristics, and difficulty in achieving free‐standing growth. Herein, it is demonstrated that two‐dimensional (2D) free‐standing GeS1−xSex (0 ≤ x ≤ 1) nanoplates can be grown by low‐pressure rapid physical vapor deposition (LPRPVD), fulfilling a continuously composition‐tunable optical bandgap and electronic band structure. By leveraging the synergistic effect of composition‐dependent modulation and free‐standing growth, GeS1−xSex‐based optoelectronic devices exhibit significantly configurable hole mobility from 6.22 × 10−4 to 1.24 cm2V−1s⁻1 and tunable responsivity from 8.6 to 311 A W−1 (635 nm), as x varies from 0 to 1. Furthermore, the polarimetric sensitivity can be tailored from 4.3 (GeS0.29Se0.71) to 1.8 (GeSe) benefiting from alloy engineering. Finally, the tailored imaging capability is also demonstrated to show the application potential of GeS1−xSex alloy nanoplates. This work broadens the functionality of conventional binary materials and motivates the development of tailored polarimetric optoelectronic devices.

AbstractAdaptive metabolic responses and innate metabolites hold promising therapeutic potential for stroke, while targeted interventions require a thorough understanding of underlying mechanisms. Adiposity is a noted modifiable metabolic risk factor for stroke, and recent research suggests that it benefits neurological rehabilitation. During the early phase of experimental stroke, the lipidomic results showed that fat depots underwent pronounced lipolysis and released fatty acids (FAs) that feed into consequent hepatic FA oxidation and ketogenesis. Systemic supplementation with the predominant ketone beta‐hydroxybutyrate (BHB) is found to exert discernible effects on preserving blood‐brain barrier (BBB) integrity and facilitating neuroinflammation resolution. Meanwhile, blocking FAO‐ketogenesis processes by administration of CPT1α antagonist or shRNA targeting HMGCS2 exacerbated endothelial damage and aggravated stroke severity, whereas BHB supplementation blunted these injuries. Mechanistically, it is unveiled that BHB infusion is taken up by monocarboxylic acid transporter 1 (MCT1) specifically expressed in cerebral endothelium and upregulated the expression of tight junction protein ZO‐1 by enhancing local β‐hydroxybutyrylation of H3K9 at the promoter of TJP1 gene. Conclusively, an adaptive metabolic mechanism is elucidated by which acute lipolysis stimulates FAO‐ketogenesis processes to restore BBB integrity after stroke. Ketogenesis functions as an early metabolic responder to restrain stroke progression, providing novel prospectives for clinical translation.

AbstractThe photoreceptor cilium is vital for maintaining the structure and function of the retina. However, the molecular mechanisms underlying the photoreceptor cilium integrity and retinal homeostasis are largely unknown. Herein, it is shown that kinesin family member 11 (KIF11) localizes at the transition zone (connecting cilium) of the photoreceptor and plays a crucial role in orchestrating the cilium integrity. KIF11 depletion causes malformations of both the photoreceptor ciliary axoneme and membranous discs, resulting in photoreceptor degeneration and the accumulation of drusen‐like deposits throughout the retina. Mechanistic studies show that the stability of KIF11 is regulated by an interplay between its UFMylation and ubiquitination; UFMylation of KIF11 at lysine 953 inhibits its ubiquitination by synoviolin 1 and thereby prevents its proteasomal degradation. The lysine 953‐to‐arginine mutant of KIF11 is more stable than wild‐type KIF11 and also more effective in reversing the ciliary and retinal defects induced by KIF11 depletion. These findings identify a critical role for KIF11 UFMylation in the maintenance of photoreceptor cilium integrity and retinal homeostasis.
Stereoconvergent Approach to the Enantioselective Construction of α‐Quaternary Alcohols by Radical Epoxide Allylation

Published: April 2024

AbstractWe describe a highly stereoconvergent radical epoxide allylation towards diastereomerically and enantiomerically enriched α‐quaternary alcohols in two steps from olefins. Our approach combines the stereospecifity and enantioselectivity of the Shi epoxidation with the unprecedented Ti(III)‐promoted intramolecular radical group transfer allylation of epoxides. A directional isomerization step via configurationally labile radical intermediates enables the selective preparation of all‐carbon quaternary stereocenters in a unique fashion.
