description: The CBM experiment will investigate heavy-ion collisions at beam energies from 8 to 45 AGeV at the future accelerator facility FAIR. The goal of the experiment is to study the QCD phase diagram in the region of moderate temperatures and highest net-baryon densities in search of the first-order phase transition from confined to deconfined matter at the QCD critical point. To do so, CBM aims to measure rare hadronic, leptonic and photonic probes among them open charm. In order to reject the rich background generated by the heavy ion collisions, a micro vertex detector (MVD) providing an unprecedented combination of high rate capability and radiation hardness, very light material budget and excellent granularity is required. In this work, we will present and discuss the concept of this detector.

description: Tumor-associated carbonic anhydrases IX (CAIX) and XII (CAXII) have long been in the spotlight as potential new targets for anti-cancer therapy. Recently, CAIX/CAXII specific inhibitor SLC-0111 has passed clinical phase I study and showed differential response among patients with colorectal cancer (CRC). CRC can be classified into four different consensus molecular subgroups (CMS) showing unique expression patterns and molecular traits. We questioned whether there is a CMS-related CAIX/CAXII expression pattern in CRC predicting response. As such, we analyzed transcriptomic data of tumor samples for CA9/CA12 expression using Cancertool. Protein expression pattern was examined in preclinical models comprising cell lines, spheroids and xenograft tumors representing the CMS groups. Impact of CAIX/CAXII knockdown and SLC-0111 treatment was investigated in 2D and 3D cell culture. The transcriptomic data revealed a characteristic CMS-related CA9/CA12 expression pattern with pronounced co-expression of both CAs as a typical feature of CMS3 tumors. Protein expression in spheroid- and xenograft tumor tissue clearly differed, ranging from close to none (CMS1) to strong CAIX/CAXII co-expression in CMS3 models (HT29, LS174T). Accordingly, response to SLC-0111 analyzed in the spheroid model ranged from no (CMS1) to clear (CMS3), with moderate in CMS2 and mixed in CMS4. Furthermore, SLC-0111 positively affected impact of single and combined chemotherapeutic treatment of CMS3 spheroids. In addition, combined CAIX/CAXII knockdown and more effective treatment with SLC-0111 reduced clonogenic survival of CMS3 modelling single cells. In conclusion, the preclinical data support the clinical approach of targeted CAIX/CAXII inhibition by showing linkage of expression with response and suggest that patients with CMS3-classified tumors would most benefit from such treatment.

description: Although high-risk human papillomavirus infection is a well-established risk factor for cervical cancer, other co-factors within the local microenvironment may play an important role in the development of cervical cancer. The current study aimed to characterize the cervicovaginal microbiota in women with premalignant dysplasia or invasive cervical cancer compared with that of healthy women. The study comprised 120 Ethiopian women (60 cervical cancer patients who had not received any treatment, 25 patients with premalignant dysplasia, and 35 healthy women). Cervicovaginal specimens were collected using either an Isohelix DNA buccal swab or an Evalyn brush, and ribosomal RNA sequencing was used to characterize the cervicovaginal microbiota. Shannon and Simpson diversity indices were used to evaluate alpha diversity. Beta diversity was examined using principal coordinate analysis of weighted UniFrac distances. Alpha diversity was significantly higher in patients with cervical cancer than in patients with dysplasia and in healthy women (p < 0.01). Beta diversity was also significantly different in cervical cancer patients compared with the other groups (weighted UniFrac Bray-Curtis, p < 0.01). Microbiota composition differed between the dysplasia and cervical cancer groups. Lactobacillus iners was particularly enriched in patients with cancer, and a high relative abundance of Lactobacillus species was identified in the dysplasia and healthy groups, whereas Porphyromonas, Prevotella, Bacteroides, and Anaerococcus species predominated in the cervical cancer group. In summary, we identified differences in cervicovaginal microbiota diversity, composition, and relative abundance between women with cervical cancer, women with dysplasia, and healthy women. Additional studies need to be carried out in Ethiopia and other regions to control for variation in sample collection.

description: The collective reorganization of electrons into a charge density wave has long served as a textbook example of an ordered phase in condensed matter physics. Two-dimensional square lattices with $p$ electrons are well-suited to the realization of charge density waves, due to the anisotropy of the $p$ orbitals and the resulting one dimensionality of the electronic structure. In spite of a long history of study of charge density waves in square-lattice systems, few reports have recognized the significance of a hidden orbital degree of freedom. The degeneracy of $p_x$ and $p_y$ electrons may give rise to orbital patterns in real space that endow the charge density wave with additional broken symmetries or unusual order parameters. Here, we use scanning tunneling microscopy to visualize the internal structure of the charge-density-wave state of CeSbTe, which contains Sb square lattices with 5$p$ electrons. We image atomic-sized, anisotropic lobes of charge density with periodically modulating anisotropy, which we interpret in terms of a superposition of $p_x$ and $p_y$ bond density waves. Our results support the fact that delocalized $p$ orbitals can reorganize into emergent electronic states of matter.

description: We investigate reaction mechanisms occurring in heavy ion collisions at low energy (around 20 MeV/u). In particular, we focus on the competition between fusion and break-up processes (Deep-Inelastic and fragmentation) in semi-peripheral collisions, where the formation of excited systems in various conditions of shape and angular momentum is observed. Adopting a Langevin treatment for the dynamical evolution of the system configuration, described in terms of shape observables such as quadrupole and octupole moments, we derive fusion/fission probabilities, from which one can finally evaluate the corresponding fusion and break-up cross sections. The dependence of the results on shape, angular momentum and excitation energy is discussed.

description: The cloud forests of the Taita Hills are valuable refuges for numerous endemic and rare animal and plant species. They also provide various ecosystem services that support subsistence farming. Due to the large-scale destruction and conversion of these species-rich natural forests into subsistence agriculture and plantations of exotic tree species, most of the natural cloud forest habitats have disappeared and ecosystem services have been significantly diminished. Despite numerous conservation initiatives, the destruction of the Taita Hills forest ecosystem continues, which also lowers livelihood quality of the local people. During a workshop with representatives of GOs, NGOs, researchers and representatives of the local community we identified potential factors which are essential to reverse this negative trend. We found that governance structures urgently need to be strengthened, and that the traditional conservation system needs to get transformed and revitalised. The basic prerequisite is a vital communication among generations, especially between the youth and the elders, as well as and improved communication of scientific knowledge to policy makers and the society. Furthermore, it is essential to harmonize stakeholders’ mandates, policies and actions to efficiently restore this unique forest biodiversity hotspot, and to secure livelihood needs for the local people.

Year: 2023

description: Background—Hemodynamic depression, including bradycardia and hypotension, is among the most common complications of carotid angioplasty and stenting. Methods and Material—A prospective, cross-sectional study was conducted at Shiraz University of Medical Sciences in southern Iran from 2011 to 2013. Consecutive patients undergoing carotid angioplasty and stenting were included. Demographic data, atherosclerotic risk factors, preprocedural blood pressure, the site of stenosis, the degree of stenosis, and data regarding technical factors were recorded. Hemodynamic depression was defined as a systolic blood pressure less than 90 mmHg and/or heart rate less than 50 beat/min. Results—About 170 patients (67% male, mean age: 71+9.8, 55.9% right side, 82.9% symptomatic) were recruited. Mean degree of stenosis was 79.4% in operated side and 40.7% in nonoperated side. Predilation, postdilation, or both were conducted in 18(10.5%), 141(83%), 11(6.5%) patients respectively. Thirteen (7.6%), 41(24%), and 12(7%) of patients developed postprocedural bradycardia, hypotension or both, respectively. Two patients had a stroke after CAS and periprocedural mortality was 0%. Hemodynamic depression after CAS had a significant association with preprocedure blood pressure and the use of an open cell stent design, but not with atherosclerotic risk factors, site and/or degree of stenosis, predilation, or postdilation. Hemodynamic depression significantly increased hospital stay too. Conclusion—Preprocedural hydration and close-cell stents may decrease the risk of poststenting hemodynamic depression

description: Background—When a patient with carotid artery stenosis presents emergently with acute ischemic stroke, the optimum treatment plan is not clearly defined. If intervention is warranted, and open surgery is prohibitive, endovascular revascularization may be performed. The use of stents places the patient at additional risk due to their thrombogenic potential. The intent of this study was to compare outcomes following endovascular approaches (angioplasty alone vs. stent) in the setting of acute stroke. Methods—We extracted a population from the National Inpatient Sample (2012) and the Nationwide Inpatient Sample (2003–2011) composed of patients with carotid artery stenosis with infarction that were admitted nonelectively and received endovascular revascularization. Patients treated with mechanical thrombectomy or thrombolysis were excluded. Categorical variables were compared between treatment groups with Chi-squared tests. Binary logistic regression was performed to evaluate mortality and iatrogenic stroke while controlling for age, case severity, and comorbidity burden. Results—About 6,333 admissions met our criteria. A majority were treated via stenting (89%, n = 5,608). The angioplasty-alone group had significantly higher mortality (9.0% vs. 3.8%, p < 0.001) and iatrogenic stroke rate (3.9% vs. 1.9%, p < 0.001) than the stent group. The adjusted odds ratios of mortality and iatrogenic stroke for patients treated with angioplasty alone were 1.953 (p < 0.001) and 1.451 (p = 0.105), respectively, in comparison to patients treated with carotid stenting

description: Pubic hair removal is a body modification practice done worldwide for different socio-cultural reasons, which is more common in women than in men, more common in younger than in older people, and more common in sexually active people than in abstinent individuals. Since there is no medical indication for genital epilation and depilation, with a few exceptions, there is only very limited evidence in the literature about the methods used and their risks. In order to provide users with guidance from a dermatological perspective on the use of different procedures and associated risks, the existing data were collected, analyzed and evaluated in a systematic literature search. For this purpose, a total of 290 articles in the English- and German-language scientific literature were identified in databases (PubMed, Google Scholar) according to defined search strategies, and 61 publications with scientific significance were identified after assessing relevance. It became clear that depilation methods (shaving, trimming, chemical depilation) are used more frequently compared to epilation methods (waxing, sugaring, mechanical epilation, electro-epilation, laser, intense pulsed light, drug epilation). The different risks and undesirable effects were analyzed in a method-associated manner and prophylactic strategies to avoid complications were developed.

description: We report the identification of 32 transiting-planet candidates in HATNet field G205. We describe the procedures that we have used to follow up these candidates with spectroscopic and photometric observations, and we present a status report on our interpretation of the 28 candidates for which we have follow-up observations. Eight are eclipsing binaries with orbital solutions whose periods are consistent with their photometric ephemerides; two of these spectroscopic orbits are singled-lined and six are double-lined. For one of the candidates, a nearby but fainter eclipsing binary proved to be the source for the HATNet light curve, due to blending in the HATNet images. Four of the candidates were found to be rotating more rapidly than vsini = 50 km/s and were not pursued further. Thirteen of the candidates showed no significant velocity variation at the level of 0.5 to 1.0 km/s . Seven of these were eventually withdrawn as photometric false alarms based on an independent reanalysis using more sophisticated tools. Of the remaining six, one was put aside because a close visual companion proved to be a spectroscopic binary, and two were not followed up because the host stars were judged to be too large. Two of the remaining candidates are members of a visual binary, one of which was previously confirmed as the first HATNet transiting planet, HAT-P-1b. In this paper we confirm that the last of this set of candidates is also a a transiting planet, which we designate HAT-P-8b, with mass Mp = 1.52 +/- 0.18/0.16 Mjup, radius Rp = 1.50 +/- 0.08/0.06 Rjup, and photometric period P = 3.076320 +/- 0.000004 days. HAT-P-8b has an inflated radius for its mass, and a large mass for its period. The host star is a solar-metallicity F dwarf, with mass M* = 1.28 +/- 0.04 Msun and Rp = 1.58 +/- 0.08/0.06 Rsun.

Biological ion exchange and its application in drinking water systems
Creators: name: Zimmermann, Karl
Publisher: name: University of British Columbia
Year: 2025

description: Natural organic matter in drinking water interferes with disinfection, threatening public health. Measured as dissolved organic carbon (DOC), organics removal is typically needed around 40- 60% of influent concentrations. Biological ion exchange (BIEX) combines the excellent DOC removal of ion exchange (IEX) with the minimal maintenance of biological activated carbon (BAC) filters. This research programme described the mechanisms of DOC removal during the long-term operations of BIEX filters. Water quality analyses of continuous flow columns enabled the description of three mechanisms for DOC removal. During ‘primary IEX’, chloride is released while DOC, sulphate and nitrate are removed. After chloride exhaustion, ‘secondary IEX’ begins where sulphate is released, and DOC and nitrate are removed. ‘Biodegradation’ occurs throughout. Strongly basic anionic (SBA) resins during primary and secondary IEX exhibited 62% and 35% DOC removal, respectively, while weakly basic anionic (WBA) resins exhibited 31% during both primary and secondary IEX; WBA resins are recommended for systems operating in secondary IEX. Next, the contributions of biologically-mediated DOC removal during BIEX was merely 5% and similar to BAC filters, despite differences in microbial community compositions. In another study, the presence of a biofilm decreased DOC removal by 7% but was accompanied by an 8% increase from biologically active resins. These findings suggest that the detriment of a biofilm’s presence is offset by its biological contributions. Understanding these findings, it was concluded that sulphate-based secondary IEX is the most important mechanisms for BIEX performance and should be prioritized over biologically mediated processes in future water system designs. Finally, long term success of drinking water systems requires a water partnership between diverse stakeholders and especially the water users. The final study shares water stories and recommendations from water leaders worldwide towards building collaborative water partnerships. Foremost, a three-step process of Awareness, Education and Resources empowers people to participate in decision-making processes, critical to sustainable access to safe drinking water. This research increased the knowledge of BIEX fundamentals and provided design recommendations. With increased understandings, biological ion exchange filters are well positioned as a tool for safe water provision across Canada and the World.

description: Polymer self-assembly leading to cooling-induced hydrogel formation is relatively rare for synthetic polymers and typically relies on H-bonding between repeat units. Here, we describe a non-H-bonding mechanism for a cooling-induced reversible order–order (sphere-to-worm) transition and related thermogelation of solutions of polymer self-assemblies. A multitude of complementary analytical tools allowed us to reveal that a significant fraction of the hydrophobic and hydrophilic repeat units of the underlying block copolymer is in close proximity in the gel state. This unusual interaction between hydrophilic and hydrophobic blocks reduces the mobility of the hydrophilic block significantly by condensing the hydrophilic block onto the hydrophobic micelle core, thereby affecting the micelle packing parameter. This triggers the order–order transition from well-defined spherical micelles to long worm-like micelles, which ultimately results in the inverse thermogelation. Molecular dynamics modeling indicates that this unexpected condensation of the hydrophilic corona onto the hydrophobic core is due to particular interactions between amide groups in the hydrophilic repeat units and phenyl rings in the hydrophobic ones. Consequently, changes in the structure of the hydrophilic blocks affecting the strength of the interaction could be used to control macromolecular self-assembly, thus allowing for the tuning of gel characteristics such as strength, persistence, and gelation kinetics. We believe that this mechanism might be a relevant interaction pattern for other polymeric materials as well as their interaction in and with biological environments. For example, controlling the gel characteristics could be considered important for applications in drug delivery or biofabrication.

description: We present the quantum phase transition in two capacitively coupled arrays of superconducting quantum dots (SQD). We consider the presence of gate voltage in each superconducting island. We show explicitly that the co-tunneling process involves with two coupled SQD arrays, near the maximum charge frustration line is not sufficient to explain the correct quantum phases with physically consistent phase boundaries. We consider another extra co-tunneling process along each chain to explain the correct quantum phases with physically consistent phase boundaries. There is no evidence of supersolid phase in our study. We use Bethe-ansatz and Abelian bosonization method to solve the problem

A combined experimental and computational study to explore the electronic structure of carbon nitride (CNx) and its building blocks
Creators: name: Zarama Buritica, Jessica V.
Publisher: name: University of British Columbia
Year: 2024

description: There is a pressing need for safe and efficient water remediation methods, and photocatalysis is one such option. In this context, carbon nitride (CNx), is gaining prominence as a metal-free and cost-effective photocatalytic polymer that shows promise in addressing issues such as arsenic contamination. However, a limiting factor is the polymer's dispersibility and ability to interact with oxyanions in water. Modification of the CNx surface, through methylation of CNx amino end-groups, is one route to increasing the polymer’s solubility ability to bind anions. Previous work showed that while the methylation of the monomer of CNx (melamine) and smaller polymers is possible, the same methodologies are not transferable to the larger and functional CNx polymer (melon). This thesis explores the challenges associated with the methylation of CNx polymers using a combination of experimental and ab initio computational techniques. The inhibition of methylation is attributed to strong non-covalent interactions between individual polymer chains, and effective methylation is facilitated by the exfoliation of CNx. The findings in this work unlock viable alternative pathways to CNx modification.
Acute Middle Cerebral Artery Occlusion Treated by Thrombectomy in a Patient with Myelodysplastic Syndrome and Severe Thrombocytopenia

description: Objective—Experience on thrombolysis and/or thrombectomy for acute major ischemic strokes in the setting of deep (less than 40,000/mm3 ) thrombocytopenia is limited. Methods—Case report and review of the literature. Results—A 63-year-old female with myelodysplastic syndrome presented with left middle cerebral artery stroke within 2 hours of symptom onset. Severe thrombocytopenia (10.000/mm3 ) precluded systemic thrombolysis. However, endovascular thrombectomy provided successful recanalization and dramatic clinical recovery with NIHSS score decreasing from 20 to 2 soon after the procedure. Her modified Rankin scale was 1 at the end of the third month. Conclusion—This exceptional case highlights that neurothrombectomy could be feasible and of justifiable merit even in the setting of critically low thrombocytopenia if a meticulous procedure is followed in subjects with severe acute stroke

description: We deal with the $n$-dimensional nonlinear Schrödinger equation (NLSE) with a cubic nonlocal nonlinearity and an anti-Hermitian term, which is widely used model for the study of open quantum system. We construct asymptotic solutions to the Cauchy problem for such equation within the formalism of semiclassical approximation based on the Maslov complex germ method. Our solutions are localized in a neighbourhood of few points for every given time, i.e. form some spatial pattern. The localization points move over trajectories that are associated with the dynamics of semiclassical quasiparticles. The Cauchy problem for the original NLSE is reduced to the system of ODEs and auxiliary linear equations. The semiclassical nonlinear evolution operator is derived for the NLSE. The general formalism is applied to the specific one-dimensional NLSE with a periodic trap potential, dipole-dipole interaction, and phenomenological damping. It is shown that the long-range interactions in such model, which are considered through the interaction of quasiparticles in our approach, can lead to drastic changes in the behaviour of our asymptotic solutions.

description: Unidirectional non-crimp fabrics (UD-NCFs) provide an excellent lightweight potential for high-performance components due to their straight fibers. However, during forming they are prone to wrinkling and gapping compared to woven or biaxial textiles. The unidirectional reinforcement direction requires the consideration of different deformation modes during modeling besides shear, which is the main deformation mode of most models for woven or biaxial textiles [1]. A hyperelastic model is proposed to describe the membrane behavior of UD-NCFs based on superimposed shear, transverse tension and compression perpendicular to the fiber rovings [2]. The membrane deformation modes are related to suitable invariants based on principle material directions of the UD-NCF.
Experimental off-axis tension tests with bias angles of 30°, 45° and 60° are used to impose different ratios of superimposed strains [3] and subsequently parameterize the model, cf. Figure 1b. The resulting approach is validated by forming simulations of a hemisphere and tetrahedron geometry, cf. Figure 1c. Good qualitative and quantitative agreement with experimental tests is achieved for the outer contour after forming as well as the strains measured by digital image correlation.

description: This paper analyses different categories of legacy from socialist central planning policies (SCPP) for urban development. How have city-specific measures by SCPP affected local economic systems, and have there been long-term consequences for cities even after their return to a market economy? Drawing from case studies of four East German cities, we identify several types of socialist policy measures that determine the local economic performance up to now. The impact of some measures was primarily displayed via ‘soft’ factors such as local image and identity and the attitudes of residents, local decision-makers.

description: The Friedberg-Lee (FL) symmetry is generated by a transformation of a fermionic field $q$ to $q + ξz$. This symmetry puts very restrictive constraints on allowed terms in a Lagrangian. Applying this symmetry to $N$ fermionic fields, we find that the number of independent fields is reduced to $N-1$ if the fields have gauge interaction or the transformation is a local one. Using this property, we find that a seesaw model originally with three generations of left- and right-handed neutrinos, with the left-handed neutrinos unaffected but the right-handed neutrinos transformed under the local FL translation, is reduced to an effective theory of minimal seesaw which has only two right-handed neutrinos. The symmetry predicts that one of the light neutrino masses must be zero.

description: Background: Most plant-pathogenic Xanthomonas bacteria harbor transcription activator-like effector (TALE) genes, which function as transcriptional activators of host plant genes and support infection. The entire repertoire of up to 29 TALE genes of a Xanthomonas strain is also referred to as TALome. The DNA-binding domain of TALEs is comprised of highly conserved repeats and TALE genes often occur in gene clusters, which precludes the assembly of TALE-carrying Xanthomonas genomes based on standard sequencing approaches. Results: Here, we report the successful assembly of the 5 Mbp genomes of five Xanthomonas strains from Oxford Nanopore Technologies (ONT) sequencing data. For one of these strains, Xanthomonas oryzae pv. oryzae (Xoo) PXO35, we illustrate why Illumina short reads and longer PacBio reads are insufficient to fully resolve the genome. While ONT reads are perfectly suited to yield highly contiguous genomes, they suffer from a specific error profile within homopolymers. To still yield complete and correct TALomes from ONT assemblies, we present a computational correction pipeline specifically tailored to TALE genes, which yields at least comparable accuracy as Illumina-based polishing. We further systematically assess the ONT-based pipeline for its multiplexing capacity and find that, combined with computational correction, the complete TALome of Xoo PXO35 could have been reconstructed from less than 20,000 ONT reads. Conclusions: Our results indicate that multiplexed ONT sequencing combined with a computational correction of TALE genes constitutes a highly capable tool for characterizing the TALomes of huge collections of Xanthomonas strains in the future.

description: We study Brownian motion driven with both conservative and nonconservative external forces. By using the thermodynamic approach of the theory of Brownian motion we obtain the Fokker-Planck equation and derive expressions for the Fluctuation Theorem in local equilibrium and in quasi-equilibrium. In local equilibrium the expressions we obtain coincide with previous results.

description: The COVID-19 pandemic is a burden for the worldwide healthcare systems. Whereas a clear age-dependent mortality can be observed, especially multimorbid and frail persons are at an increased risk. As bio-functional rather than calendrical age is in the meanwhile known to play a crucial role for COVID-19-related outcomes, aging-associated risk factors, overall prognosis and physiological age-related changes should be systematically considered for clinical decision-making. In this overview, we focus on cellular senescence as a major factor of biological aging, associated with organ dysfunction and increased inflammation (inflammaging).

description: Background: We discuss a rare case of an adult patient with different pathologies involving the aortic and pulmonary valves in need of surgery. Case presentation: The patient had a history of congenital PV stenosis and surgical valvuloplasty. Almost 50 years later the patient underwent a complex second heart surgery due to infective endocarditis of the aortic valve and high-grade restenosis of the pulmonary valve. Replacement of the aortic and pulmonary valve, as well as reconstruction of the RVOT and closure of a persistent foramen ovale, followed. Postoperative course was uneventful and the patient was discharged home a week after surgery. Conclusion: Simultaneous surgery of pulmonary and aortic valves due to different pathologies is rare but can be performed successfully even in advanced age and can improve quality of life.

description: Aim: To explore the implications for dentists and family doctors of the association between periodontal and systemic diseases and the role of dentists and family doctors in managing non-communicable diseases (NCDs) and promoting healthy lifestyles. Materials and Methods: The consensus reports of the previous Focused Workshops on the associations between periodontitis and diabetes (2017) and periodontitis and cardiovascular diseases (2019) formed the technical reviews to underpin discussions on both topics. For the association with respiratory diseases, a systematic review was specifically commissioned for the Workshop discussions. Working groups prepared proposals independently, and then the proposals were discussed and approved at plenary meetings. Results: Periodontitis is independently associated with cardiovascular diseases, diabetes, chronic obstructive pulmonary disease (COPD), obstructive sleep apnea and COVID-19 complications. Dentists and family doctors should collaborate in managing NCDs, implementing strategies for early detection of periodontitis in primary care centres and of cardiovascular diseases or diabetes in dental settings. Family doctors should be informed about periodontal diseases and their consequences, and oral health professionals (OHPs) should be informed about the relevance of NCDs and the associated risk factors. Conclusions: Closer collaboration between OHPs and family doctors is important in the early detection and management of NCDs and in promoting healthy lifestyles. Pathways for early case detection of periodontitis in family medicine practices and of NCDs in dental practices should be developed and evaluated.
Efficient readout of micromechanical resonator arrays in ambient conditions

description: We present a method for efficient spectral readout of mechanical resonator arrays in dissipative environments. Magnetomotive drive and detection is used to drive double clamped resonators in the nonlinear regime. Resonators with almost identical resonance frequencies can be tracked individually by sweeping the drive power. Measurements are performed at room temperature and atmospheric pressure. These conditions enable application in high throughput resonant sensor arrays.

description: Lasioglossum is a large genus of halictid bees with high species diversity in morphologically rather cryptic species groups. With more than 1900 described species, the taxonomy of the genus is complex and largely unresolved in many regions. For practical reasons, systematic reviews are restricted in scope either geographically or to particular species groups. In this study we focus on the subgenus Dialictus of the genus Lasioglossum from the Yucatán Peninsula in Mexico. In previous studies we identified members of the genus as important pollinators of cash crops in the region, and genetic analyses suggested the existence of seven molecular taxonomic units (mOTU). Based on additional morphological differences, we here describe these mOTUs as novel species, Lasioglossum (Dialictus) yucatanense Landaverde-González sp. nov., L. (D.) paxtoni Landaverde-González sp. nov., L. (D.) ameshoferi Landaverde-González sp. nov., L. (D.) aureoviride Landaverde-González & Husemann sp. nov., L. (D.) paralepidii Gardner sp. nov., L. (D.) milpa Landaverde-González sp. nov. and L. (D.) nanotegula Landaverde-González & Husemann sp. nov., and provide keys and images to assist in their identification.
title: INVESTIGATION OF MULTISCALE MECHANISMS OF DYNAMIC DEFORMATION AND FRACTURE OF 1565 ALUMINUM ALLOY UNDER PLANE COLLISION AND HIGH-VELOCITY PENETRATION

description: High strength 1565 aluminum alloy was tested within impact velocity range of 250-
750 m/s in two schemes of shock loading: (i) under uniaxial strain conditions and (ii) in highvelocity penetration. The combination of load regimes allows the different stages of
multiscale structure formation to be retraced. The intensity of macro-meso momentum
exchange is found to be responsible for both resistance to spallation and high-velocity
penetration. The overall impact velocity region is found to be subdivided by three sub-regions
of different mechanisms of dynamic straining and scales. The strength behavior of material
differs for different regions of impact velocities. Within impact velocity regions where the
resistance to penetration increases, the spall strength decreases. The transition from one scale
level to another is shown to be realized through the excitation of velocity oscillations at the
mesoscale.

description: We present a comprehensive study of the exchange bias effect in a model system. Through numerical analysis of the exchange bias and coercive fields as a function of the antiferromagnetic layer thickness we deduce the absolute value of the averaged anisotropy constant of the antiferromagnet. We show that the anisotropy of IrMn exhibits a finite size effect as a function of thickness. The interfacial spin disorder involved in the data analysis is further supported by the observation of the dual behavior of the interfacial uncompensated spins. Utilizing soft x-ray resonant magnetic reflectometry we have observed that the antiferromagnetic uncompensated spins are dominantly frozen with nearly no rotating spins due to the chemical intermixing, which correlates to the inferred mechanism for the exchange bias.

description: Using a combination of local spin density and Hubbard 1 approximations we study the mechansim of exchange interacion in EuX (X=O, S, Se and Te). We reproduce known experimental results about bulk modulus, critical pressure for structural phase transition, magnetic ordering temperature, spin--wave dispersions as well as momentum-- and tempearuture--dependent band shift. Our numerical results show pressure induced competition between the hybirization enhanced exchange interaction and Kondo--like coupling in EuO. Possible ways to enhance T_{c} are discussed.
