Evaluation of Horn Bud Wound Healing Following Cautery Disbudding of Dairy Calves With and Without the Use of Oxytetracycline Aerosol Spray
Authors: Ridgway Rachel , Neary Joseph , Turner Andrea , Barrett David C. , Gillespie Amy 
Published: February 2022

Oxytetracycline is commonly applied as a topical agent to burn lesions post cautery disbudding of calves. Judicial use of antibiotics dictates that they should only be used where necessary to reduce the development of resistance in target bacteria. The objective of this study, therefore, was to evaluate the efficacy of topical oxytetracycline spray on wound healing post cautery disbudding of dairy calves over a 6-week period. Dairy calves were disbudded by veterinarians, technicians, or veterinary surgeons, using a standard cautery disbudding protocol. Oxytetracycline spray was randomly applied to the right or left horn bud of each animal (OXY), while the other horn bud received no antibiotic spray (NA). The outcomes measured were wound diameter (WD) and lesion score (LS), either normal healing (NH) or abnormal healing (AH). These assessments were conducted every 14 days following disbudding, until 42 days. A total of 360 animals completed the study. There was a difference in wound diameter and lesion score on day 14 post disbudding between the two groups. Cautery lesions sprayed with oxytetracycline (OXY) were 0.5 ± 0.15 mm smaller than NA lesions (P = 0.001), and there were fewer abnormal healing lesions for OXY compared to the NA (2.5 vs. 11%, respectively; P ≤ 0.001). There were no differences at day 28 and day 42 post disbudding, and on day 42, 34% of wounds had healed in both groups.In summary, the authors were unable to demonstrate a difference in healing between the groups using the described methods.
Mandibular Thickness Measurements as Predictive Tool for Specific Dental Disorders in Alpacas (Vicugna Pacos)
Authors: Proost Kirsten , Pardon Bart , Vlaminck Lieven 
Published: February 2022

BackgroundOral health in alpacas is often neglected until severe dental disease becomes evident under the form of a pronounced mandibular swelling with or without fistulation. Mandibular thickness measurements might serve as an easy tool to screen for early increases in thickness thereby identifying alpacas which could benefit from an oral examination.ObjectiveTo study specific risk factors, including age, gender, level of performed measurements and dental disorders, associated with mandibular thickness in alpacas. To determine suitable cutoff values for mandibular thickness at specific locations for the development of a diagnostic test to identify animals with dental disorders.Study designCross-sectional study.MethodsMandibular thickness was measured at standardized locations in 216 alpacas using a Vernier caliper. Risk factors for an increased mandibular thickness were collected through oral examination in sedated animals and by interview of the respective owner. A multivariable linear mixed model was built to identify factors associated with mandibular thickness. Cutoff values for specific dental disorders were obtained after receiver operating characteristics (ROC)-curve analysis.ResultsMandibular thickness was 0.43 ± Standard Error 0.21 mm [95% Confidence interval (CI) = 0.02-0.84 mm] higher at locations where interproximal gum recession was present (P = 0.039). Severe dental disease caused an increase in thickness of 1.90 mm (95% CI= 1.29-2.51 mm) (P &lt; 0.001). Mandibular thickness with a cutoff of 19.4 mm showed a high accuracy for predicting severe dental disease (Se = 0.41; Sp = 0.92). Specifically, thickness at a level perpendicular to the medial canthus of the eye proved a more precise predictor for severe dental disease (AUC, 0.85; 95% CI 0.74-0.96; P &lt; 0.001) with a lower cutoff of 18.5 mm and Sn and Sp of 0.52 and 0.82, respectively.Main limitationsNo radiographic or computed tomographic studies were available to support the diagnosis of dental and/or apical disease.ConclusionMandibular thickness measurements in alpacas can aid early detection of animals in need of specialized dental care. Most animals with an increased mandibular thickness suffer from advanced dental disease. However, routine dental examinations remain necessary to allow the early detection of dental disorders in alpacas.

В представленном сообщении приведено описание 4 случаев развития спонтанных забрюшинных гематом в области подвздошно-поясничной мышцы у пожилых пациентов с тяжелой формой клинического течения инфекции COVID-19 на фоне антикоагулянтной терапии. Данное осложнение проявлялось неспецифическими симптомами, такими как анемия, гематурия, дискомфорт и парестезии в поясничной или переднебоковой поверхности живота, появление боли в гипогастрии и, как крайний вариант, гемодинамическая нестабильность с явлениями гиповолемического (геморрагического) шока. В описанных клинических случаях гематома подвздошно-поясничной мышцы была верифицирована с помощью ряда диагностических исследований (ультразвукового исследования органов брюшной полости и мягких тканей и/или компьютерной томографии). Установление диагноза спонтанной гематомы требовало временной приостановки назначения антикоагулянтной терапии. После проведения консервативного лечения трое из четырех пациентов были выписаны из стационара с выздоровлением.
This report describes 4 cases of spontaneous retroperitoneal hematomas in the iliopsoas muscle in elderly patients with severe clinical course of COVID-19 infection during anticoagulant therapy. This complication was manifested by nonspecific symptoms, such as anemia, hematuria, discomfortand paresthesia in the lumbar or anterolateral surface of the abdomen, appearance of pain in hypogastrium and, as an extreme variant, hemodynamic instability with symptoms of hypovolemic (hemorrhagic) shock. In the defined clinical cases, the hematoma of the iliopsoas muscle was verified using a number of diagnostic studies (ultrasound examination of the abdominal organs and soft tissues, and/or computed tomography). Establishing the diagnosis of spontaneous hematoma required a temporary suspension of anticoagulant therapy. After conservative treatment, three out of four patients were discharged from the hospital with recovery.
Multidisciplinary Approach to Differential Diagnosticsof Human Neoplasms: Interface “Clinical Parameters – Cellular Ultrastructure” in Endometrial Intraepithelial Neoplasia and Cancer
Authors: Сафарова C.И. 
Published: February 2022

Настоящее исследование предпринято с целью: 1) установления значимости и надежности специфических ультраструктурных критериев для дифференциальной диагностики и выявления возможной корреляции между клиническими параметрами (включая гистологический диагноз) и ультраструктурой опухолевых клеток. В частности, установлено, что качественные и количественные вариации на субклеточном уровне позволяют выделить четкие ультраструктурные критерии эндометриальной интраэпителиальной неоплазии и рака эндометрия, которые с высокой вероятностью могут быть использованы в диагностике и прогнозе. Так, в качестве наиболее выраженных субклеточных критериев малигнизации можно привести изменения в ультраструктуре клеточного ядра, ядерной оболочки и ядрышек. Кроме того, показано, что в каждом конкретном случае, т. е. при каждом конкретном диагнозе, специфическая ультраструктурная картина, соответствующая строго определенным клиническим параметрам, позволяет выделить варианты как с потенциально малым/высоким риском малигнизации, так и с крайне пессимистическим прогнозом.
This study was performed with the following goals: 1) to estimate the significance and value of specific ultrastructural criteria for differential diagnostics and 2) to reveal possible correlation between clinical parameters (including histological diagnosis) and ultrastructure of tumor cells. We demonstrated specific quantitative and qualitative subcellular variations that allowed us to outline strict ultrastructural criteria of intraepithelial endometrial neoplasia and cancer. Importantly, these criteria can be used in clinical practice with diagnostic and prognostic purposes. Specificultrastructural changes of the cell nucleus, nuclear envelope, and nucleolus are considered as the most profound subcellular malignization criteria. Moreover, we demonstrated that in each diagnosis, the specific ultrastructural features and clinical parameters were concomitant. This allowed us to define several clinical variants with potentially high/low risk of malignization, as well as with extremely pessimistic prognosis.

Abstract
Flexible and stretchable electronics present opportunities for transition from rigid bulky devices to soft and conformal systems. However, such technology requires mechanical design and integration strategies to enhance robustness and form factor. In addition, scalable and reliable fabrication pathways are needed to facilitate the high volume manufacturing required to satisfy a growing market demand. This report describes recent advances in design, manufacture, and reliability of flexible and stretchable electronics technology. Flexible concept devices for physiological monitoring are introduced, before discussion of high throughput fabrication of stretchable electronics, then hybrid integration of conventional rigid components on stretchable carrier substrates with an emphasis on a need for further developments in device reliability testing procedures. Finally, consideration is given to transition options for more eco-conscious device constituents. These cases progress flexible and stretchable electronics towards robust, fully integrated, unobtrusive devices incorporating sustainable components.
Bonding performance in atomic diffusion bonding of wafers using amorphous Si thin films with smooth surface
Authors: Amino T. , Uomoto M. , Shimatsu T. 
Published: February 2022

Abstract
Amorphous Si films with a low surface roughness of 0.13 nm were used to examine the bonding performance of atomic diffusion bonding of quartz glass wafers at room temperature in vacuum. The high bonding strength was achieved for films with thickness δ of 2–50 nm: the blade could not be inserted between the bonded wafers. Using a vacuum chamber with a base pressure of 1 × 10–6 Pa, the great bonding strength was maintained even with waiting time in vacuum of as long as 3.6 × 103 s from film deposition to bonding. The excellent bonding performance was almost equal to that achieved using Ti films.

Published: February 2022

We introduce $H$-chromatic symmetric functions, $X_{G}^{H}$, which use the $H$-coloring of a graph $G$ to define a generalization of Stanley's chromatic symmetric functions. We say two graphs $G_1$ and $G_2$ are $H$-chromatically equivalent if $X_{G_1}^{H} = X_{G_2}^{H}$, and use this idea to study uniqueness results for $H$-chromatic symmetric functions, with a particular emphasis on the case $H$ is a complete bipartite graph. We also show that several of the classical bases of the space of symmetric functions, i.e. the monomial symmetric functions, power sum symmetric functions, and elementary symmetric functions, can be realized as $H$-chromatic symmetric functions. Moreover, we show that if $G$ and $H$ are particular types of multipartite complete graphs we can derive a set of $H$-chromatic symmetric functions that are a basis for $\Lambda^n$. We end with some conjectures and open problems.
Tiling Enumeration of Hexagons with Off-Central Holes
Authors: Lai Tri 
Published: February 2022

This paper is the sequel of the author's previous paper about tiling enumerations of the cored versions of a doubly-intruded hexagon (Electron. J. Combin. 2020), in which we generalized Ciucu's work about $F$-cored hexagons (Adv. Math. 2017). This paper provides an extensive list of thirty tiling enumerations of hexagons with three collinear chains of triangular holes. Besides two chains of holes attaching to the boundary of the hexagon, we remove one more chain of triangles that is slightly off the center of the hexagon. Two of our enumerations imply two conjectures posed by Ciucu, Eisenkolbl, Krattenthaler, and Zare (J. Combin. Theory Ser. A 2001).
Substructure at High Speed. I. Inferring the Escape Velocity in the Presence of Kinematic Substructure
Authors: Necib Lina , Lin Tongyan 
Published: February 2022

Abstract
The local escape velocity provides valuable inputs to the mass profile of the galaxy, and requires understanding the tail of the stellar speed distribution. Following Leonard & Tremaine, various works have since modeled the tail of the stellar speed distribution as

∝

(

v

esc

−
v
)

k

, where v
esc is the escape velocity, and k is the slope of the distribution. In such studies, however, these two parameters were found to be largely degenerate and often a narrow prior is imposed on k in order to constrain v
esc. Furthermore, the validity of the power-law form can breakdown in the presence of multiple kinematic substructures or other mis-modeled features in the data. In this paper, we introduce a strategy that for the first time takes into account the presence of kinematic substructure. We model the tail of the velocity distribution as a sum of multiple power laws as a way of introducing a more flexible fitting framework. Using mock data and data from FIRE simulations of Milky Way-like galaxies, we show the robustness of this method in the presence of kinematic structure that is similar to the recently discovered Gaia Sausage. In a companion paper, we present the new measurement of the escape velocity and subsequently the mass of the Milky Way using Gaia eDR3 data.

Abstract
Thanks to ground-based infrared and submillimeter observations the study of the dusty torus of nearby active galactic nuclei has greatly advanced in the last years. With the aim of further investigating the nuclear mid-infrared emission of the archetypal Seyfert 2 galaxy NGC 1068, here we present a fitting to the N- and Q-band Michelle/Gemini spectra. We initially test several available spectral energy distribution (SED) libraries, including smooth, clumpy and two-phase torus models, and a clumpy disk+wind model. We find that the spectra of NGC 1068 cannot be reproduced with any of these models. Although, the smooth torus models describe the spectra of NGC 1068 if we allow variation of some model parameters among the two spectral bands. Motivated by this result, we produced new SEDs using the radiative transfer code SKIRT. We use two concentric tori that allow us to test a more complex geometry. We test different values for the inner and outer radii, half-opening angle, radial, and polar exponent of the power-law density profile, opacity, and viewing angle. Furthermore, we also test the dust grains’ size and different optical and calorimetric properties of silicate grains. The best-fitting model consists of two concentric components with outer radii of 1.8 and 28 pc, respectively. We find that the size and the optical and calorimetric properties of graphite and silicate grains in the dust structure are key to reproducing the spectra of NGC 1068. A maximum grain size of 1 μm leads to a significant improvement in the fit. We conclude that the dust in NGC 1068 reaches different scales, where the highest contribution to the mid-infrared is given by a central and compact component. A less dense and extended component is present, which can be either part of the same torus (conforming a flared disk) or can represent the emission of a polar dust component, as already suggested from interferometric observations.
A Nuclear Equation of State Inferred from Stellar r-process Abundances

Published: February 2022

Abstract
Binary neutron star mergers (NSMs) have been confirmed as one source of the heaviest observable elements made by the rapid neutron-capture (r-) process. However, modeling NSM outflows—from the total ejecta masses to their elemental yields—depends on the unknown nuclear equation of state (EOS) that governs neutron star structure. In this work, we derive a phenomenological EOS by assuming that NSMs are the dominant sources of the heavy element material in metal-poor stars with r-process abundance patterns. We start with a population synthesis model to obtain a population of merging neutron star binaries and calculate their EOS-dependent elemental yields. Under the assumption that these mergers were responsible for the majority of r-process elements in the metal-poor stars, we find parameters representing the EOS for which the theoretical NSM yields reproduce the derived abundances from observations of metal-poor stars. For our proof-of-concept assumptions, we find an EOS that is slightly softer than, but still in agreement with, current constraints, e.g., by the Neutron Star Interior Composition Explorer, with R
