Terahertz Birefringence and Dichroism of KTA Crystal

For the first time, we present the spectra of all three components of the refractive index and absorption coefficient of the KTiOAsO4 (KTA) crystal measured by the means of terahertz time-domain spectroscopy in the range of 0.3–2.1 THz. The dispersion of the refractive index is approximated and presented in the form of the Sellmeier equation. We observe a large birefringence ΔnZ-X ≈ 0.76 and dichroism which is attributed to a strong absorption peak in the vicinity of ~1.23–1.25 THz for the Z-axis. However, the crystal can be considered as almost uniaxial due to a close value of nX and nY as well as αX ≈ αY in the region below 0.5 THz. Moreover, KTA crystals can satisfy the phase-matching condition in principal XZ-plane for THz emission on difference frequency generation mechanism. Therefore, the crystal could be considered as an efficient candidate for terahertz wave generator under intense laser pump.
Learning from olive evolution and cultivation to understand the diversity of associated plant-parasitic nematodes communities in Morocco

Plant-parasitic nematodes (PPN) significantly contribute to economic losses in the top-ten olive producing countries, especially in the Mediterranean basin. Instead of controlling the main pathogenic nematode species as usual, one innovative strategy to control PPN would be to manage diversity in communities in order to lead them to be less pathogenic. Then, knowing assemblage mechanisms in communities due to evolution and environmental forces is a prerequisite. This study was conducted in Morocco, because (i) information about PPN diversity is lacking, (ii) different forms of olive occur as wild (including two sub species O. europaea subsp. europaea and subsp. Maroccana), feral and typical cropping systems as traditional and high density and as irrigated or not) are present. Morphobiometric observations revealed a very diverse parasite nematofauna (117 species), seven new taxa being recorded for the first time on olive. Tylenchidae, Hoplolaimidae and Telotylenchidae nematodes were dominant (80% of the samples), whereas root-knot nematodes (Meloidogyne spp.) were detected in 40% of the samples. Multivariate analyzes showed that the development of Heteroderidae and Longidoridae nematodes was favored in PPN communities on wild olive, while lesion (Pratylenchidae) and root-knot nematodes multiply in orchards. Three Meloidogyne species were identified: M. javanica on feral and cultivated olive in southern and center Morocco; M. arenaria and M. hapla on wild olive in the north. Cytochrome oxidase I (COI) and Internal transcribed spacer-2 (ITS2) genes were good markers for species differentiation, but they were not able to distinguish M. javanica and M. arenaria populations and were not adapted for intraspecific differentiation. However, a significant morphological variability was observed between the Meloidogyne species, and within and between M. javanica populations. The response of the diversity of PPN communities as well as of Meloidogyne populations to olive genotype, geo-climatic zones and soil physico-chemical characteristics, and diversity of plants associated with olive trees is discussed.
Translingual Youth Podcasts as Acoustic Allies: Writing and Negotiating Identities at the Intersection of Literacies, Language and Racialization

ABSTRACT U.S. Latinx youth from immigrant backgrounds bring to schools their transnational literacies, complex lived experiences of marginalization and resistance, and politicized translanguaging practices that are seldom recognized in classrooms. This article examines U.S. Latinx bilingual youth who participated in a podcast project within a Chicanx/Latinx Studies high school course that mobilized their bilingualism for literacy instruction. This ethnographic classroom study explores a curricular unit that allowed young people to use new media technologies to tell important stories of themselves and their social worlds at a time of heightened anti-immigrant sentiments in the United States. Through translanguaging and translingual frames, I demonstrate how Latinx young people contest racist narratives, reclaim who they are, and author new spaces for solidarity. Findings detail the ways that students utilized podcasts as a tool to promote creativity and self-expression, and to connect personal experiences to broader pressing discourses about immigration, language, racialization processes, and resistance.
Potential of Dual-Frequency Radar and Microwave Radiometer Synergy for Water Vapor Profiling in the Cloudy Trade Wind Environment

High-resolution boundary layer water vapor profile observations are essential for understanding the interplay between shallow convection, cloudiness, and climate in the trade wind atmosphere. As current observation techniques can be limited by low spatial or temporal resolution, the synergistic benefit of combining ground-based microwave radiometer (MWR) and dual-frequency radar is investigated by analyzing the retrieval information content and uncertainty. Synthetic MWR brightness temperatures, as well as simulated dual-wavelength ratios of two radar frequencies are generated for a combination of Ka and W band (KaW), as well as differential absorption radar (DAR) G-band frequencies (167 and 174.8 GHz, G2). The synergy analysis is based on an optimal estimation scheme by varying the configuration of the observation vector. Combining MWR and KaW only marginally increases the retrieval information content. The synergy of MWR with G2 radar is more beneficial due to increasing degrees of freedom (4.5), decreasing retrieval errors, and a more realistic retrieved profile within the cloud layer. The information and profile below and within the cloud is driven by the radar observations, whereas the synergistic benefit is largest above the cloud layer, where information content is enhanced compared to an MWR-only or DAR-only setup. For full synergistic benefits, however, G-band radar sensitivities need to allow full-cloud profiling; in this case, the results suggest that a combined retrieval of MWR and G-band DAR can help close the observational gap of current techniques.
Case report: A fatal case of aortic and mitral valve endocarditis caused by Streptobacillus moniliformis

Abstract Background Infective endocarditis (IE) secondary to rat-bite fever (RBF) is rare but potentially lethal. Rapid diagnosis is of utmost prognostic importance. However, the diagnosis of RBF is challenging because Streptobacillus moniliformis does not grow under conventional culture conditions. Case summary A 65-year-old male without previous cardiac history presented with sudden onset of balance problems and facial palsy. For 2 weeks, he had experienced intermittent fever and myalgia. Transoesophageal echocardiography (TOE) revealed severe mitral and aortic valve IE with aortic root abscess. The patient underwent a double biological valve replacement. Blood cultures remained negative after 9 days of incubation. However, sub-cultivation on solid media demonstrated the growth of pleomorphic Gram-negative rods, identified as S. moniliformis. After 4 weeks of antibiotic therapy, he was discharged. One month later, control TOE showed valve excrescences and aortic annular aneurysm. Despite comprehensive surgery, antibiotic treatment, and intensive care, the patient died 1 week after reoperation. Discussion A fatal outcome of S. moniliformis IE is rare. The majority of previous cases describe underlying valvular abnormalities or death due to insufficient antimicrobial therapy. Here, the patient had no prehistory of valvular heart disease and despite appropriate antibiotics, the outcome was fatal. Rapid diagnosis of RBF IE has prognostic implications. Identification of S. moniliformis is, however, difficult, because the bacterium is fastidious and does not grow under standard laboratory conditions. Therefore, diagnosis often relies on clinical symptoms or a history of rodent exposure. Close attention to this disease by clinicians, in addition to, dialogue with clinical microbiologists is essential.
Physical, Psychological, and Social Challenges in Patients with Hepatitis B Infection

Context: Hepatitis B is the most prevalent chronic viral infection in humans, which imposes limitations on patients and has many physical, psychological, and social consequences due to its chronic nature. The purpose of this study was to evaluate the physical, psychological, and social challenges of patients with hepatitis B virus (HBV). Evidence Acquisition: First, a set of keywords, including hepatitis B, challenge, physical, psychological, and social, were searched in databases, such as Google Scholar, PubMed, SID, Magiran, and IranMedex. Then, the articles published between 2009 and 2019 were reviewed according to the inclusion and exclusion criteria in two stages – the title and the abstract in the first stage and the whole paper in the second stage. Finally, 34 articles were selected out of 1426 articles. Results: The articles used in this study were as follows: descriptive and cross-sectional studies (10 articles), review studies (9 articles), qualitative studies (9 articles), cohort studies (3 articles), randomized controlled trials, mixed-methods studies, and field studies (one article each). Most studies had considered patients with hepatitis B with an emphasis on physical issues (10 articles), social stigma (7 articles), psychological reactions (5 articles), the discovery of patients’ experiences (3 articles), and discrimination (2 articles). In 25 studies, the samples were patients with HBV. Conclusions: It is necessary to understand and support the patients to treat them properly and help them live with minimum challenges and limitations. Therefore, it is necessary to consider educational and counseling programs to identify different aspects of this disease.

Genetic differentiation between Mediterranean and Atlantic populations of the common prawn Palaemon serratus (Crustacea: Palaemonidae) reveals uncommon phylogeographic break

The Atlantic–Mediterranean transition zone between the Alborán Sea and the Gulf of Cádiz constitutes the most prominent marine geographic barrier in European waters and includes known phylogeographic breaks such as the Strait of Gibraltar and the Almería-Oran Front. A genetic shift in this area has been previously documented for the European littoral shrimp Palaemon elegans. Here we carried out a phylogeographic analysis with the congeneric and sympatric species Palaemon serratus to test for similar intraspecific genetic differentiation and geographic structure. This littoral prawn is distributed in the Northeastern Atlantic Ocean, the Mediterranean Sea and the Black Sea. We compared DNA sequences from the mitochondrial genes Cox1 and to a lesser extent from 16S rRNA of several Atlantic and Mediterranean populations. Furthermore, sequences from the nuclear gene Enolase were included for corroborating differences between Mediterranean and Atlantic individuals. A pronounced genetic differentiation was detected between the Mediterranean and Atlantic populations, amounting to 10.14% in Cox1 and 2.0% in 16S, indicating the occurrence of two independent evolutionary lineages. Interestingly, specimens from the Atlantic Gulf of Cadiz cluster together with the Mediterranean individuals, indicating that a biogeographic barrier appears to be located west of the Strait of Gibraltar.
Effects of extreme high flow events on macroinvertebrate communities in Vermont streams

Heavy precipitation events and subsequent high flows are occurring with greater frequency and intensity, which could have substantial implications for biomonitoring programs that typically evaluate changes in biological condition due to stressors at local and watershed scales. In this study we evaluated response and recovery of macroinvertebrate communities at nine reference quality streams located in multiple watersheds throughout Vermont to flooding from Tropical Storm (TS) Irene in 2011. At each site, the Vermont Department of Environmental Conservation (VT DEC) had collected macroinvertebrate data on an annual basis from 2009–2013. We compared the data collected in the days and weeks following TS Irene (2011) to samples collected for 2 years prior to the event (2009–2010) and 2 years after (2012–2013). While most metrics used in Vermont's biocriteria did not demonstrate a response to TS Irene, density showed a significant reduction in 2011 (across sites, percent change ranged from −24 to −91%; mean −66%). The percent change in density at each site was significantly correlated with the amount of localized rainfall during the storm (rs = −0.79, p = .02) and was most evident at small to medium‐sized, high gradient streams. Reduced density caused several of these sites to fail to meet minimum criteria for biological integrity, though densities rebounded the following year. While the quick recovery indicated resiliency at these reference streams, the timing and magnitude of flood events may decrease the ability of biomonitoring programs to accurately evaluate the effect of watershed stressors.
Laser Oscillating Welding of TC31 High-Temperature Titanium Alloy

The joining of high-temperature titanium alloy is attracting much attention in aerospace applications. However, the defects are easily formed during laser welding of titanium alloys, which weakens the joint mechanical properties. In this work, laser oscillating welding was applied to join TC31 high-temperature titanium alloy. The weld appearance, microstructure and mechanical properties of the laser welds were investigated. The results show that sound joints were formed by using laser oscillating welding method, and a large amount of martensite was presented in the welds. High mechanical properties were achieved, which was approaching to (or even equaled) the strength of the base material. The joints exhibited a tensile strength of up to 1200 ± 10 MPa at room temperature and 638 ± 6 MPa at 923 K. Laser oscillating welding is beneficial to the repression of porosity for welding high-temperature titanium alloy.
Chlorovibrissea korfii sp. nov. from northern hemisphere and Vibrissea flavovirens new to China

A new species, Chlorovibrissea korfii, is described and illustrated, which is distinct from other members of the genus by the overall pale greenish apothecia 0.8–2.0 mm in diam. and 0.6–1.5 mm high, J+ asci 70–83 × 4.5–5.5 μm, and non-septate ascospores 44–52 × 1.2–1.5 μm. This is the first species of Chlorovibrissea reported from northern hemisphere. Vibrissea flavovirens is reported from China for the first time. Sequence analyses of the internal transcribed spacer of nuclear ribosomal DNA are used to confirm the affinity of the two taxa.
Twinning in Zr-Based Metal-Organic Framework Crystals

Ab initio structure determination of new metal-organic framework (MOF) compounds is generally done by single crystal X-ray diffraction, but this technique can yield incorrect crystal structures if crystal twinning is overlooked. Herein, the crystal structures of three Zirconium-based MOFs, that are especially prone to twinning, have been determined from twinned crystals. These twin laws (and others) could potentially occur in many MOFs or related network structures, and the methods and tools described herein to detect and treat twinning could be useful to resolve the structures of affected crystals. Our results highlight the prevalence (and sometimes inevitability) of twinning in certain Zr-MOFs. Of special importance are the works of Howard Flack which, in addition to fundamental advances in crystallography, provide accessible tools for inexperienced crystallographers to take twinning into account in structure elucidation.
Time-series classification for industrial applications: a brake pad wear prediction use case

Brake system is an important part for control of a vehicle. Hence condition monitoring of brake pads is essential for ensuring passenger’s safety. Many existing methods for brake pads wear assessment rely on specific sensors installed in the brake system, which could be expensive. Instead we use data from existing vehicle’s sensors and electronic control unit that are readily available in modern vehicles. We reduced the prediction problem to time-series classification problem and developed and tested several classification pipelines based on machine learning. We demonstrated that it is possible to predict a brake pad wear with an accuracy sufficient for real-life usage.
Morphological Assessment of Pathological Changes * 1

Routine histological examination of the rat larynx, from inhalation toxicity and carcinogenicity studies, has been routinely performed in this laboratory for over 15 yr. This work has identified the larynx as an important target organ with a number of pharmaceuticals, industrial chemicals, agricultural chemicals, and environmental pollutants. The rat larynx contains 5 epithelial types: stratified squamous; low squamoid; respiratory; and 2 forms of pseudostratified cuboidal epithelium. Each epithelial type has a specific location within the relatively complex anatomical configuration of the larynx. The detection of induced changes requires a consistent, thorough and detailed histological examination in order to identify the often subtle changes in the distribution of these epithelial types. Induced lesions show distinct predilection sites, including the ventro-lateral regions anterior to the ventral pouch and the inner aspects of the arytenoid projections. Lesions commonly involve degeneration of the original epithelial cells with subsequent regeneration; hyperplasia and squamous metaplasia. In more severe reactions, the larynx may illustrate epithelial ulceration with exudation. To some extent the changes commonly observed are dependent upon the duration of the study and the dose level employed, rather than the individual compound. Recovery or regression of induced changes is variable and dependent upon the time scale involved and severity or type of initial lesion.
Learning to teach for mathematical proficiency: Behavioural changes for pre-service teachers on teaching placement

This study reports on an investigation of how field experiences in teaching prepares pre-service teachers (PSTs) to effectively deal with the challenges and complexities of teaching mathematics in Zimbabwean secondary schools. The study was premised on the view that improvement in learning secondary school mathematics in the classroom is related to practitioner development in teaching. However, despite overwhelming research on mathematics knowledge for teachers, the problem of mathematics failure in high schools has not been addressed. A mixed methods approach, based on the perspectives of PSTs on teaching practice (TP) was employed to depict how their practices impact on their knowledge development for teaching mathematics. The study, found that a proficient mathematics PST is considered one who embraces knowledge of mathematics content and the ability to teach it. Hence, the development of mathematics knowledge for PSTs requires them to be mentored and workshopped by mathematics subject specialists who are well positioned in terms of mathematics pedagogy and mathematics content knowledge.
Development, Characterization and In Vitro Evaluation of Paclitaxel and Anastrozole Co-Loaded Liposome

Paclitaxel (PTX) and anastrozole (ANA) have been frequently applied in breast cancer treatment. PTX is well-known for its anti-proliferative effect meanwhile ANA has just been discovered to act as an estrogen receptor α (ERα) ligand. The combination therapy of PTX and ANA is expected to improve treating efficiency, as ANA would act as a ligand binding with the ERα gene expressed in breast cancer cells and thereafter PTX would inhibit the division and cause death to those cancer cells. In this study, liposome-based nanocarriers (LP) were developed for co-encapsulation of PTX and ANA to improve the efficacy of the combined drugs in an Estrogen receptor-responsive breast cancer study. PTX-ANA co-loaded LP was prepared using thin lipid film hydration method and was characterized for morphology, size, zeta potential, drug encapsulation and in vitro drug release. In addition, cell proliferation (WST assay) and IN Cell Analyzer were used for in vitro cytotoxicity studies on a human breast cancer cell line (MCF-7). Results showed that the prepared LP and PTX-ANA-LP had spherical vesicles, with a mean particle size of 170.1 ± 13.5 nm and 189.0 ± 22.1 nm, respectively. Controlled and sustained releases were achieved at 72 h for both of the loaded drugs. The in vitro cytotoxicity study found that the combined drugs showed higher toxicity than each single drug separately. These results suggested a new approach to breast cancer treatment, consisting of the combination therapy of PTX and ANA in liposomes based on ER response.
Does Facebook activity reveal your dark side? Using online language features to understand an individual’s dark triad and needs

ABSTRACT Language is a powerful indicator of psychological processes. This study analysed the language features on online social networks to understand individuals’ Dark Triad personality and need for power. Results based on data from 130 individuals using the Linguistic Inquiry and Word Count (LIWC) dictionary showed that language features such as I-words, negative emotion, and clout were positively related to Machiavellianism, which was positively associated with the need for power. We also found indirect effects of Analytic, I-words, and Social words on the need for power through Narcissism and indirect effects of Analytic and Authenticity on the need for power through Psychopathy. In addition, gender moderated the relationship between I-words and Machiavellianism, in that the relationship was stronger for men than for women. Finally, we built a regression model using language features to predict individuals’ Dark Triad and the need for power. Based on the findings, we put forward some suggestions for managers to recruit and promote appropriate employees.
