description: La tesela es una pequeña pieza de piedra, terracota o vidrio coloreado que se utiliza para confeccionar un mosaico. La palabra proviene del latín tessella que, a su vez, procede del término griego τεσσερες (wikipedia).La historia del desarrollo de la cartografía, en ambos lados del mundo (oriente y occidente), responde a los avances tecnológicos. En el derrotero cartográfico, observamos como los acuerdos y consideraciones personales o grupales, señalan a las generaciones futuras el marco de referencia en que deben expresar su entorno real y sus nuevos espacios. En respuesta al estado de sofisticación que hemos alcanzado con las tecnologías informáticas, nos ha sido posible disponer de un Atlas Dinámico del Orbe; mediante el conjunto de herramientas tecnológicas de servicios de mapas que actualmente se ofertan en Internet. Entre ellas resalta la herramienta de mapas y otros servicios de Google[i], que en un sentido estricto se han convertido en una Cosmografía; un espacio virtual lleno de certezas e incertezas.Google Maps en forma general, no es más que una sofisticada herramienta tecnológica informática, que en base a consideraciones propias y otras estandarizadas desde la antigüedad, establece un marco referencial donde es posible desplegar diversos tipos de mapas dinámicos y estáticos; con una estructura de capas de información superpuestas, con contenido de objetos híper vinculados a una diversidad de nuevas fuentes de información gráfica y documental sobre la web.Algunos detalles del marco referencial cartográfico de GoogleMaps son discutidos en este artículo, que tiene un objetivo concreto, pero que también pretende convertirse en un discurso explicativo de una tecnología mistificada y cerrada; pero que en razón de la herencia tecnológica, es propia de todos los pueblos del mundo.Tesela.pl (v.1.0 / junio 2011) fue una colaboración del autor para el Centro de Sismologia de la Universidad de Oriente.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: To better understand and ultimately respond to chemical and biological terrorism, academic and law enforcement communities need to establish a closer interaction between their respective realms. This paper attempts to bridge strategist scholarly and policy considerations on chemical and biological terrorism into one unique risk-assessment. The paper has devised a novel approach and reconstructs the phases of commission – firstly, the acquisition of knowledge on chemical and biological (CB) agents, secondly, the acquisition of CB materials, thirdly, the development of the CB weapon and finally, the execution of the attack – that constitute the key units for the analysis. At each perpetration phase the discussion analyses the challenges that the offenders need to tackle. By way of a case study the thesis then evaluates the effectiveness of the respective Australian and EU-level counter CB terrorism provisions to pinpoint their vulnerabilities. The analysis has attempted to identify unregulated or insufficiently regulated areas of the aforementioned counter strategies and has suggested where policy gaps can be addresses by academic considerations.

description: Статья посвящена методам повышения степени переработки растительного сырья, используемого в производстве напитков различной крепости, что повышает конкурентоспособность предприятия и экологическую безопасность технологического процесса. Приведена информация о факторах, влияющих на процесс экстракции, способах, позволяющих интенсифицировать этот процесс. В статье представлены результаты исследований влияния предварительной обработки мяты перечной звуком слышимого диапазона с целью увеличения выхода технологически ценных компонентов растительного сырья в экстракте. Установлено наличие значимого воздействия звука на процесс экстракции компонентов мяты перечной. Выявлено, что показатели экстракта могут как улучшаться, так и ухудшаться по сравнению с контрольными в зависимости от частоты звука, применяемого для обработки опытных образцов. Исследовано влияние на результаты экстракции ряда параметров предварительной акустической обработки: частоты и мощности звука, продолжительности воздействия на экспериментальный образец мяты перечной. Установлено, что наибольшее увеличение выхода сухих веществ в экстракте и его цветности обеспечила акустическая обработка при частоте 11 000 Гц в течение 40 мин при мощности равной 40 % от максимальной у источника звука, использованного в эксперименте (3 Вт). Указанный режим предварительного воздействия звуком на мяту перечную обеспечил увеличение выхода сухих веществ на 16–20 % и повышение цветности экстракта на 13–21 % по сравнению с контролем. На основании представленных результатов исследований сделан вывод о перспективности применения акустической обработки в производственном масштабе.

description: Owing to fundamental differences in female and male reproductive biology, selection is expected to favour the evolution of different phenotypes in each sex. This can give rise to sexually antagonistic selection when beneficial alleles for one sex are deleterious when expressed in the other. Despite intensive study, previous research on sexually antagonistic selection has focused on species with physically separates sexes and internal fertilization. Here, I explore the consequences of sexual conflict and sexually antagonistic selection for the maintenance of genetic variation, and the evolution of reproductive and life-history traits in two non-traditional, but common, groups: external fertilizers and hermaphrodites.

description: Objective- Heart rate monitoring using wrist type Photoplethysmographic (PPG) signals is getting popularity because of construction simplicity and low cost of wearable devices. The task becomes very difficult due to the presence of various motion artifacts. The objective is to develop algorithms to reduce the effect of motion artifacts and thus obtain accurate heart rate estimation. Methods- Proposed heart rate estimation scheme utilizes both time and frequency domain analyses. Unlike conventional single stage adaptive filter, multi-stage cascaded adaptive filtering is introduced by using three channel accelerometer data to reduce the effect of motion artifacts. Both recursive least squares (RLS) and least mean squares (LMS) adaptive filters are tested. Moreover, singular spectrum analysis (SSA) is employed to obtain improved spectral peak tracking. The outputs from the filter block and SSA operation are logically combined and used for spectral domain heart rate estimation. Finally, a tracking algorithm is incorporated considering neighbouring estimates. Results- The proposed method provides an average absolute error of 1.16 beat per minute (BPM) with a standard deviation of 1.74 BPM while tested on publicly available database consisting of recordings from 12 subjects during physical activities. Conclusion- It is found that the proposed method provides consistently better heart rate estimation performance in comparison to that recently reported by TROIKA, JOSS and SPECTRAP methods. Significance- The proposed method offers very low estimation error and a smooth heart rate tracking with simple algorithmic approach and thus feasible for implementing in wearable devices to monitor heart rate for fitness and clinical purpose.

description: The existence of bound states induced by local impurities coupled to an insulating host depends decisively on the global topological properties of the host's electronic structure. In this context, we consider magnetic impurities modelled as classical unit-length spins that are exchange-coupled to the spinful Haldane model on the honeycomb lattice. We investigate the spectral flow of bound states with the coupling strength $J$ in both the topologically trivial and Chern-insulating phases. In addition to conventional $k$-space topology, an additional, spatially local topological feature is available, based on the space of impurity-spin configurations forming, in case of $R$ impurities, an $R$-fold direct product of two-dimensional spheres. Global $k$-space and local $S$-space topology are represented by different topological invariants, the first ($k$-space) Chern number and the $R$-th ($S$-space) spin-Chern number. We demonstrate that there is a local $S$-space topological transition as a function of $J$ associated with a change in the spin Chern number and work out the implications of this for the $J$-dependent local electronic structure close to the impurities and, in particular, for in-gap bound states. The critical exchange couplings' dependence on the parameters of the Haldane model, and thus on the $k$-space topological state, is obtained numerically to construct local topological phase diagrams for systems with $R=1$ and $R=2$ impurity spins.

description: This paper proposes a time-zone vector autoregression (VAR) model to investigate comovements in the global financial market. Analyzing daily data from 36 national equity markets, we explore the subprime and European debt crises using static analysis and the COVID-19 crisis through a rolling window method. Our study of comovements using VAR coefficients reveals a resonance effect in the global system. Findings on densities and assortativities suggest the existence of the transmission mechanism in all periods and abnormal structural changes during the crises. Strength analysis uncovers the information transmission mechanism across continents over normal and turmoil periods and emphasizes specific stock markets' unique roles. We examine dynamic continent strengths to demonstrate the contagion mechanism in the global equity market over an extended period. Incorporating the time-zone effect significantly enhances the VAR model's interpretability. Signed networks provide more information on global equity markets and better identifies critical contagion patterns than unsigned networks.

description: Majorana fermions can be realized as quasiparticles in topological superconductors, with potential applications in topological quantum computing. Recently, lattices of magnetic adatoms deposited on the surface of s-wave superconductors - Shiba lattices - have been proposed as a new platform for topological superconductivity. These systems possess the great advantage that they are accessible via scanning-probe techniques, and thus enable the local manipulation and detection of Majorana modes. Realizing quantum bits on this basis will rely on the creation of nanoscopic Shiba lattices, so-called Shiba islands. Here, we demonstrate that the topological Majorana edge modes of such islands display universal electronic and transport properties. Most remarkably, these Majorana modes possess a quantized charge conductance that is proportional to the topological Chern number, C, and carry a supercurrent whose chirality reflects the sign of C. These results establish nanoscopic Shiba islands as promising components in future topology-based devices.

description: Recent years have seen a momentum shift emerging in the development of wireless communication devices, with software-defined radios advocated for devices which are flexible, adaptive and reconfigurable. The burgeoning demand for communication and data services ‘anytime, anywhere' is placing unprecedented pressure on how radio frequency spectrum is provisioned and managed. The potential is there for cognitive radios to be able to identify channels which are underutilized and to exploit them. By effectively sharing radio frequency channels amongst several wireless networks, an increase in the communication capacity of the existing spectrum is made possible to meet future demand. In this thesis, techniques for supporting the requisite spectrum sharing are advanced. Signal processing and learning techniques are described to better comprehend channel usage in any given radio environment. The occupancy of a channel is predicted with a lower decision error rate by learning the spectral features present in transmitted signals. It is shown that devices can statistically characterize channels based on their occupancy rate and the unpredictability of their occupancy pattern. When coupled with learning, this allows intelligent and informed channel selection that considers the long-term benefit of exploitation against the costs of channel switching and interfering with other network users. The need to strive for computational efficiency to reduce power consumption, crucial in mobile communication devices, is a recurring theme that is addressed throughout.

description: Recently, some authors have suggested that the absorption Ångström exponent (AAE) can be used to deduce the component aerosol absorption optical depths (AAODs) of carbonaceous aerosols in the AERONET database. This AAE approach presumes that AAE ≪ 1 for soot carbon, which contrasts the traditional small particle limit of AAE = 1 for soot carbon. Thus, we provide an overview of the AERONET retrieval, and we investigate how the microphysics of carbonaceous aerosols can be interpreted in the AERONET AAE product. We find that AAE ≪ 1 in the AERONET database requires large coarse mode fractions and/or imaginary refractive indices that increase with wavelength. Neither of these characteristics are consistent with the current definition of soot carbon, so we explore other possibilities for the cause of AAE ≪ 1. AAE is related to particle size, and coarse mode particles have a smaller AAE than fine mode particles for a given aerosol mixture of species. We also note that the mineral goethite has an imaginary refractive index that increases with wavelength, is very common in dust regions, and can easily contribute to AAE ≪ 1. We find that AAE ≪ 1 can not be caused by soot carbon, unless soot carbon has an imaginary refractive index that increases with wavelength throughout the visible and near-infrared spectrums. Finally, AAE is not a robust parameter for separating carbonaceous absorption from dust aerosol absorption in the AERONET database.

description: Introduction: Subglottic stenosis is a condition leading to narrowing of subglottal space due to intubation, inflammation, tracheostomy, trauma, and idiopathic conditions. Respiratory effort of the patient increases due to this narrowing. The effect is also perceived in speech production as effortful exhalation, unnatural pause due to shallow breathing, and muscle tension. Surgical treatment including cricoplasty and tracheal anastomosis can improve respiratory function but adversely affect voice production, especially in adult women. The following case study is a retrospective voice analysis of an adult female before and after cricoplasty and voice therapy. Methodology: Forty seven year female, diagnosed with Idiopathic subglottic stenosis, was seen pre and post-tailored cricoplasty. The patient underwent eighteen sessions of voice therapy. Pre-post-operative and post-therapy measures of Voice Handicap Index-10, Consensus Auditory Perceptual Evaluation – Voice, fundamental frequency, speaking fundamental frequency, perturbation measures like jitter, and shimmer were compared after therapy. Results: All the above mentioned voice measures were affected negatively after surgery; however, the patient showed substantial improvement after therapy. Transgender therapy approach helped considerably in this improvement. Conclusions: This is a single case study. The authors suggest that considering voice therapy before and after surgery may improve prognosis of patients’ voice and satisfaction of treatment.
When Judaism lost the Temple: crisis and response in 4 Ezra and 2 Baruch
Creators: name: Gore-Jones, Lydia

Subjects: Other education not elsewhere classified

description: This thesis is a study of religious thought in two Jewish apocalypses, 4 Ezra and 2 Baruch, written around the end of the first century as a response to the destruction of Jerusalem and the Temple by the Romans in 70 CE. The true nature of the crisis is the perceived loss of covenantal relationship between God and Israel, and the Jewish identity that is under threat. Discussions of various aspects of thoughts, including those conventionally termed theodicy, particularism and universalism, anthropology and soteriology, are subordinated under and contextualized within the larger issue of how the ancient authors propose to mend the traditional Deuteronomic covenantal theology now under crisis. Both 4 Ezra and 2 Baruch advocate a two-pronged solution of Torah and eschatology at the centre of their scheme to restore that covenant relationship in the absence of the Temple. Both maintain the Mosaic tradition as the bulwark for Israel's future survival and revival; whereas 4 Ezra aims to implant its eschatology into the Sinaitic tradition and make it part of the Mosaic Law, 2 Baruch extends the Deuteronomic scheme of reward and retribution into an eschatological context, making the rewards of the end-time a solution to the cycle of sins and punishments of this age. Both texts are read as coherent works with a sophisticated literary structure, skillfully composed to convey authorial intentions. As such, the overall intended message can only be grasped after one has understood the development of the narrative structure. Considerable emphases are also placed on the significance of the portrayals of the pseudonymous protagonists, Ezra and Baruch, the use of symbolism in the two texts as scriptural exegesis, as well as their relationship with each other and links with the Hebrew Bible and other Jewish and Christian writings.

description: В 1982 г. в Азербайджане было собрано 2 млн т винограда с 275 тыс. га виноградников и произведено 121,6 млн дал виноматериалов. В том же году было произведено 23,9 млн дал виноградных вин, 12,5 млн бутылок шампанского и 1599 тыс. декалитров коньяка. Для сравнения, в целом в СССР было собрано 7622 тыс. т винограда с 1374 тыс. га виноградников. Судя по всему, азербайджанские виноградники составляли около четверти виноградников страны. В тот период винодельческая отрасль в Азербайджане в основном специализировалась на производстве крепких вин, 92–95 % производимых вин приходилось на долю крепленых вин. Винная традиция страны, известная своеобразной историей, была знаменита специфическими брендами. Одним из самых известных был Кагор Кюрдамир, приготовленный по «технологии Кюрдамир». Следует отметить, что в то время в СССР было произведено 18 наименований вин по Кюрдамирской технологии. Таким образом, восстановление производства и совершенствование технологии кюрдамирских вин весьма актуальны и требуют специальных исследований. Целью исследования стало совершенствование технологии вин типа Кагор с применением различных технологических приемов. Объектами исследования послужили аборигенные и интродуцированные сорта красного винограда: Матраса, Каберне-Совиньон, Ширван шахи, Мерло, полученные из них виноматериалы. Виноград собирали в стадии технической или полной зрелости. Собранный виноград перерабатывали с применением таких способов, как по белому, по красному, термовинификация, кахетинский и кюрдамирский. Полученные образцы виноматериалов и вин исследовали с помощью существующих в энохимии органолептических и физико-химических методов анализа. Установлено, что в аборигенных и интродуцированных сортах винограда во время сбора на стадии технологической зрелости значение соотношения глюкоза: фруктоза было близко к единице (1,01–1,08). Содержание общих фенольных соединений в образцах вин, полученных с применением таких технологических методов, как брожение на мезге, нагревание мезги, брожение с гребнями и спиртование мезги, было значительно выше, чем в образцах вин, полученных по белому способу. Содержание общих фенольных соединений и их мономерных форм в вариантах со спиртованием мезги; полимерных фенольных соединений при нагревании мезги и антоцианов при брожении мезги с гребнями привлекает внимание более высокими показателями. Сумма фенолкарбоновых кислот во всех опытных виноматериалах примерно в 2 раза выше, чем в виноматериале, полученном по белому способу, а применение такого технологического метода, как спиртование мезги, позволило увеличить значение этого показателя в 2,5 раза.

description: С целью обеспечения технологических параметров производства игристых вин в процессе вторичного брожения и снижения энергозатрат на выпуск единицы продукции изучали возможность управления полем температур виноматериала в резервуаре цилиндрической формы с «рубашкой», в процессе непрерывной шампанизации на спаренных бродильных аппаратах (СБА). Были проведены исследования по изучению изменения температуры виноматериала по периметру резервуара с использованием встроенных датчиков температуры как в лабораторных, так и в производственных условиях. На основании проведенных исследований была получена математическая модель регулирования температуры игристых вин при вторичном брожении. С помощью специальной программы, реализующей математическую модель регулирования температуры, были рассчитаны теоретические кривые изменения поля температур игристого вина в резервуаре при вторичном брожении. Полученные теоретические расчеты совпали с практическими результатами на спаренных бродильных аппаратах в производственных условиях. Это позволило сделать вывод о возможности регулирования температуры игристых вин в резервуаре в процессе вторичного брожения. Экспериментальные и теоретические исследования показали, что, управляя полем температур, можно регулировать процесс охлаждения шампанизированного виноматериала и значительно сократить расход электроэнергии на охлаждение.

description: The projection factor (p-factor) is an essential component of the classical Baade-Wesselink (BW) technique, that is commonly used to determine the distances to pulsating stars. It is a multiplicative parameter used to convert radial velocities into pulsational velocities. As the BW distances are linearly proportional to the p-factor, its accurate calibration for Cepheids is of critical importance for the reliability of their distance scale. We focus on the observational determination of the p-factor of the long-period Cepheid RS Pup (P = 41.5 days). This star is particularly important as this is one of the brightest Cepheids in the Galaxy and an analog of the Cepheids used to determine extragalactic distances. An accurate distance of 1910 +/- 80 pc (+/- 4.2%) has recently been determined for RS Pup using the light echoes propagating in its circumstellar nebula. We combine this distance with new VLTI/PIONIER interferometric angular diameters, photometry and radial velocities to derive the p-factor of RS Pup using the code Spectro-Photo-Interferometry of Pulsating Stars (SPIPS). We obtain p = 1.250 +/- 0.064 (+/-5.1%), defined for cross-correlation radial velocities. Together with measurements from the literature, the p-factor of RS Pup confirms the good agreement of a constant p = 1.293 +/- 0.039 (+/-3.0%) model with the observations. We conclude that the p-factor of Cepheids is constant or mildly variable over a broad range of periods (3.7 to 41.5 days).

Interpreting students’ ability in self-assessment

description: Interpreting students need to be able to self-assess their performance during and after their education to effectively develop their interpreting skills for professional practice. Although there is a growing interest in self-assessment in interpreter education research, it is as yet an under-researched area, especially with regard to the interpreting students’ ability to self-assess. This thesis reports the results of a case study that examined interpreting students in a graduate program in Australia and its joint offshore program in Korea. Using a mixed methods approach, the students’ reflective journals, interviews with teachers, the students’ self-rated scores and teachers’ grades were examined with the aim of understanding students’ ability to assess their performance and the relationship between their self-assessment ability and interpreting performance gains over the course of their study. In addition, the impact of teacher instruction on self-assessment was examined. The findings of this research indicate that interpreting students’ self-ratings were different from their teacher-rated scores, with the majority of students underestimating their performance. In addition, their self-assessment was largely focused on the negative aspects of their performance and it appeared they might not be able to apply some of the scoring criteria adequately in making judgements about their performance. It is also apparent that teachers make assumptions about their students’ ability to apply rating criteria for self-assessment. Overall, the findings suggest that self-assessment is a complex task, that students cannot intuitively develop skills to self-assess while they are acquiring interpreting skills, and that their ability depends to some extent on the guidance they receive from their teachers.

description: Background: Dermatofibrosarcoma Protuberans (DFSP) is an exceptionally rare soft tissue tumor that spreads locally with rare metastasis limited to brain, lung, and liver. Immunocompetent patients presenting with more than one DFSP are rare. Methods and Results: A 47 year old man presented with metachronous lesions of the left mastoid skin and right supraclavicular fossa skin. Biopsies revealed DFSP in both locations. CT scans never showed bony invasion in either location. Multiple excisions and radiation therapy have resulted in no recurrence at the supraclavicular site and recurrence in the mastoid site. Conclusions: DFSP can recur despite wide and deep excision combined with radiation therapy. The treatment algorithm for DFSP in the Head and Neck region is included in our review of the literature. Long term follow up is mandatory in these patients.

description: Magnetoelectric materials have generated wide technological and scientific interest because of the rich phenomena these materials exhibit, including the coexistence of magnetic and ferroelectric orders, magnetodielectric behavior, and exotic hybrid excitations such as electromagnons. The multiferroic spinel material, CoCr$_2$O$_4$, is a particularly interesting example of a multiferroic material, because evidence for magnetoelectric behavior in the ferrimagnetic phase seems to conflict with traditional noncollinear-spin-driven mechanisms for inducing a macroscopic polarization. This paper reports an inelastic light scattering study of the magnon and phonon spectrum of CoCr$_2$O$_4$ as simultaneous functions of temperature, pressure, and magnetic field. Below the Curie temperature ($T_C \sim 94$ K) of CoCr$_2$O$_4$ we observe a $ω\sim 16 \,\text{cm}^{-1}$ $\boldsymbol q=0$ magnon having T$_{1g}$-symmetry, which has the transformation properties of an axial vector. The anomalously large Raman intensity of the T$_{1g}$-symmetry magnon is characteristic of materials with a large magneto-optical response and likely arises from large magnetic fluctuations that strongly modulate the dielectric response in CoCr$_2$O$_4$. The Raman susceptibility of the T$_{1g}$-symmetry magnon exhibits a strong magnetic-field dependence that is consistent with the magnetodielectric response observed in CoCr$_2$O$_4$, suggesting that magnetodielectric behavior in CoCr$_2$O$_4$ primarily arises from the field-dependent suppression of magnetic fluctuations that are strongly coupled to long-wavelength phonons. Increasing the magnetic anisotropy in CoCr$_2$O$_4$ with applied pressure decreases the magnetic field-dependence of the T$_{1g}$-symmetry magnon Raman susceptibility in CoCr$_2$O$_4$, suggesting that strain can be used to control the magnetodielectric response in CoCr$_2$O$_4$.

description: The aim of this paper is to analyze the suitability of the high-mountain stations Mauna Loa and Izaña for Langley plot calibration of Sun photometers. Thus the aerosol optical depth (AOD) characteristics and seasonality, as well as the cloudiness, have been investigated in order to provide a robust estimation of the calibration uncertainty as well as the number of days that are suitable for Langley calibrations. The data used for the investigations belong to the AERONET and GAW-PFR networks, which maintain reference Sun photometers at these stations with long measurement records: 22 years at Mauna Loa and 15 years at Izaña. In terms of clear-sky and stable aerosol conditions, Mauna Loa (3397 m a.s.l.) exhibits on average 377 Langley plots (243 morning and 134 afternoon) per year suitable for Langley plot calibration, whereas Izaña (2373 m a.s.l.) shows 343 Langley plots (187 morning and 155 afternoon) per year. The background AOD (500 nm) values, on days that are favorable for Langley calibrations, are in the range 0.01–0.02 throughout the year, with well-defined seasonality that exhibits a spring maximum at both stations plus a slight summer increase at Izaña. The statistical analysis of the long-term determination of extraterrestrial signals yields to a calibration uncertainty of ∼ 0.25–0.5 %, this uncertainty being smaller in the visible and near-infrared wavelengths and larger in the ultraviolet wavelengths. This is due to atmospheric variability produced by changes in several factors, mainly the AOD. The uncertainty cannot be reduced based only on quality criteria of individual Langley plots and averaging over several days is shown to reduce the uncertainty to the needed levels for reference Sun photometers.

description: Due to their atomic-scale thickness, the resonances of 2D material membranes show signatures of nonlinearities at amplitudes of only a few nanometers. While the linear dynamics of membranes is well understood, the exact relation between the nonlinear response and the resonator's material properties has remained elusive. In this work, we propose a method to determine the Young's modulus of suspended 2D material membranes from their nonlinear dynamic response. The method is demonstrated by interferometric measurements on graphene and MoS2 resonators, which are electrostatically driven into the nonlinear regime at multiple driving forces. It is shown that a set of response curves can be fitted by the solutions of the Duffing equation using only one fit parameter, from which the Young's modulus is extracted using membrane theory. Our method is fast, contactless, and provides a platform for high-frequency characterization of the mechanical properties of 2D materials.

description: Purpose: Determining optimal intensity of behavioral treatment for dysphagia has been one of the most debated topics. The purpose of the current study was to systematically review the studies that offered evidence for behavioral treatment intensity for dysphagia. Methods: A systematic search was conducted in six scientific databases using 16 different combinations of keywords, in addition to manually searching different journals for relevant articles. A total of 50,192 articles were obtained from the initial searches. After rigorous screening, only five articles met the inclusion criteria. All studies were evaluated for their methodological quality, evidence level, and for pertinent information regarding treatment intensity. Results: The results of the systematic review revealed that only one study presented sufficient information that allowed the authors to determine cumulative treatment intensity for dysphagia. The research designs employed by the studies ranged from randomized-controlled design to non-experimental retrospective design. Appraisal of the methodological quality revealed that only two articles had moderate internal validity, and the remaining articles demonstrated poor internal validity. Conclusion: The findings suggest that there is limited evidence regarding optimal behavioral treatment intensity for dysphagia, and there is a need for well-controlled group design studies to expand on this line of research.
Integrating perceptions of best practice: running an SME business in the distinctive COTS application software sector

description: How exactly the business managers of commercial off-the-shelf (COTS) application software small and medium sized enterprises (SMEs) should run their businesses is a particular problem. The market has a number of distinct characteristics and is increasingly competitive. In contrast to their larger counterparts, SMEs often have limited resources and knowledge that can be applied to strategic planning and management activities. A literature review reveals that there is no core body of research, or accepted set of concepts, that specifically address the problem in any great depth. While a wealth of generic business and strategic management reference materials exist, it is unclear exactly what the precise relevance and uptake of these is for COTS application software SME business managers. -- This study specifically investigates whether a holistic guiding management framework can be developed for running a COTS application software SME business. A grounded theory paradigm provides the theoretical basis for the research design. This was chosen to foster creativity and ensure the research is not restricted by previous thinking. The results of the research are a new model that provides a single guiding framework for managers running COTS application software SME businesses. This integrates numerous aspects of perceived best practice in a unified and holistic theoretical model. The research contributes to both scholarly and practitioner domains. A more rigorous and scientific approach to software business management theory has been developed. The ability to undertake specialised strategic consulting services for a COTS application software SME business is improved.

description: Quantum spin liquids (QSLs) are long-range entangled states of quantum magnets which lie beyond the Landau paradigm of classifying phases of matter via broken symmetries. A physical route to arriving at QSLs is via frustration-induced quantum melting of ordered states such as valence bond crystals or magnetic orders. Here, we show, using extensive exact diagonalization (ED) and density-matrix renormalization group (DMRG) studies of concrete $SU(2)$ invariant spin models on honeycomb, triangular and square lattices, that chiral spin liquids (CSLs) emerge as descendants of triple-$Q$ spin crystals with tetrahedral magnetic order and a large scalar spin chirality. Such ordered-to-CSL melting transitions may yield lattice realizations of effective Chern-Simons-Higgs field theories. Our work provides a distinct unifying perspective on the emergence of CSLs, and suggests that materials with magnetic skyrmion crystal order might provide a good starting point to search for CSLs.

description: The nose is a competent immunological organ that reflects many of the cellular and molecular events seen in mucosal immunity. Viruses are major causative agents for respiratory tract infections in children and adults. Viruses induced rhinitis is usually of acute nature resulting in the common cold symptoms; rhinorrhea, nasal obstruction, malaise and exacerbation of already existing airways disease. Among the viruses frequently infecting the human nose are the RNA virus such as coronavirus, rhinovirus, and the influenza/ parainfluenza virus and the double-stranded DNA adenovirus. These viruses induce rhinitis (common cold and flu) by attaching themselves to the lining of the nose and paranasal sinuses.
