Polarising Agents and Spin Tags for Dynamic Nuclear Polarisation (DNP)-Enhanced Solid-State Nuclear Magnetic Resonance (ssNMR) Analysis of Biological Samples
Authors: Nawaz Nighat , Patching Simon G.
Published: July 2023

Solid-state nuclear magnetic resonance (ssNMR) spectroscopy can obtain structural, functional and ligand-binding information about frozen and solid-like biological samples. ssNMR spectra can be enhanced by orders of magnitude using the technique of dynamic nuclear polarisation (DNP). In DNP there is polarisation transfer from high-gyromagnetic ratio (γ) unpaired electrons to neighbouring nuclei using microwave irradiation at or near the electron Larmor frequency. This produces an absolute increase in the signal-to-noise ratio and allows experiments on much smaller quantities of sample and/or using much shorter acquisition times. Along with necessary instrumentation an essential requirement for DNP-ssNMR is a sample with an endogenous free radical or an exogenous free radical polarising agent must be added to the sample. The polarising agent must be soluble in the sample matrix and compatible with the biological sample. The free radical(s) of the polarising agent also must be stable for the lifetime of DNP-ssNMR experiments. Nitroxides have been most used as polarising agents, including the biradical compounds TOTAPOL and AMUPol with a wide range of biological samples to produce DNP enhancement factors of up to 250. Derivatives of TOTAPOL and AMUPol and many other different polarising agents have also been used. Whilst conventional polarising agents are mixed throughout the sample, others are targeted at specific sites to provide a more localised signal enhancement. Here we review the different polarising agents and spin-tags that have been used in DNP-ssNMR studies on biological samples.

Published: July 2023

Information on crop phenology is essential when aiming to better understand the impacts of climate and climate change, management practices, and environmental conditions on agricultural production. Today’s novel optical and radar satellite data with increasing spatial and temporal resolution provide great opportunities to provide such information. However, so far, we largely lack methods that leverage this data to provide detailed information on crop phenology at the field level. We here propose a method based on dense time series from Sentinel-1, Sentinel 2, and Landsat 8 to detect the start of seven phenological stages of winter wheat from seeding to harvest. We built different feature sets from these input data and compared their performance for training a one-dimensional temporal U-Net. The model was evaluated using a comprehensive reference data set from a national phenology network covering 16,000 field observations from 2017 to 2020 for winter wheat in Germany and compared against a baseline set by a Random Forest model. Our results show that optical and radar data are differently well suited for the detection of the different stages due to their unique characteristics in signal processing. The combination of both data types showed the best results with 50.1% to 65.5% of phenological stages being predicted with an absolute error of less than six days. Especially late stages can be predicted well with, e.g., a coefficient of determination (R²) between 0.51 and 0.62 for harvest, while earlier stages like stem elongation remain a challenge (R² between 0.06 and 0.28). Moreover, our results indicate that meteorological data have comparatively low explanatory potential for fine-scale phenological developments of winter wheat.Overall, our results demonstrate the potential of dense satellite image time series from Sentinel and Landsat sensor constellations in combination with the versatility of deep learning models for determining phenological timing.

Published: July 2023

Mental health has immense impacts on educational outcomes among post-secondary students. Adjustment problems, trouble coping with stress, supporting loved ones, symptoms of mental illnesses: these experiences, and many others, are part of what students bring with them to the classroom. Promoting student well-being and reducing the impact of mental health challenges on learning is part of effective pedagogy. However, addressing student mental health deliberately and directly may feel daunting.In this chapter, we first describe why instructors should consider student mental health in course design and delivery. We then spotlight three actionable issues where instructors can make small adjustments that can have positive impacts for some students’ learning, attitudes towards education, and overall well-being. To facilitate the adoption of best practices, we provide concrete examples and directions. We close with suggestions for how instructors can develop and curate lists of mental health resources to support their studies.

Published: July 2023

The recent rise of publicly available artificial intelligence (AI) tools such as ChatGPT hasraised a plethora of questions among users and skeptics alike. One major question asks, "Has AIgained the ability to indistinguishably mimic the psychology of its organic, human counterpart?".Since music has been known to be a positive predictor of personality traits due to the individuality ofpersonal preference, in this paper we use machine learning (ML) algorithms to analyze thepredictability of AI-generated or 'synthetic' participants' Big 5 personality traits (Openness,Conscientiousness, Extraversion, Agreeableness, and Neuroticism) using their recent music listeningactivity and motivations for listening to music. Recent music listening history for syntheticparticipants is generated using ChatGPT and the corresponding audio features for the songs arederived via the Spotify Application Programming Interface (Beats per minute, Danceability,Instrumentals, Happiness, etc). This study will also administer the Uses of Music Inventory toaccount for synthetic participants’ motivations for listening to music: emotional, cognitive, andbackground. The dataset will be trained and tested on scaler-model combinations to identify thepredictions with the least mean absolute error using ML models such as Random Forest, DecisionTree, K-Nearest Neighbors, Logistic Regression, and Support Vector Machine. Both regression(continuous numeric value) and classification (Likert scale option) prediction methods will be used.An Exploratory Factor Analysis (EFA) will be conducted on the audio features to find a latentrepresentation of the dataset that machine learning is also trained and tested on. A full literaturereview showed this is the first study to use both Spotify API data, rather than self-reported musicpreference, and machine learning, in addition to traditional statistical tests and regression models, topredict the personality of a synthetic college student demographic. The findings of this study showChatGPT struggles to mimic the diverse and complex nature of human personality psychology andmusic taste. This paper is a pilot study to a broader ongoing investigation where the findings ofsynthetic participants are compared to that of real college students using the same inventories forwhich data collection is ongoing.
Understanding social judgments of, and proclivities to commit upskirting
Authors: Fido Dean , Harper Craig A. , Duff Simon , Page Thomas E.
Published: July 2023

Against a backdrop of legislative change that sees the taking of private sexual images underneath the clothing of a non-consenting other being made a criminal offence – upskirting – there is a need to understand the public’s judgments of, and motivations to perpetrate said behavior. In this study (N = 490), we investigated whether judgments of upskirting differed as a function of victim sex (male, female) and their perceived attractiveness (attractive, unattractive), as well as how variation in voyeuristic interest, belief in a just world, and psychopathic personality traits predicted judgments of, and proclivity to engage in upskirting behaviors. We consistently observed more lenient judgments of upskirting behaviors when victims were attractive and male, with such judgements predicted by older age across all conditions. Moreover, proclivity to engage in upskirting was predicted by past voyeuristic behaviors, higher psychopathic personality, and being male and of older age. We discuss our findings in the context of needing to qualitatively understand the general public’s rationale for said disparity in judgments, as well as identifying and combating barriers to disclose victimization.

Updating Measures of Work Schedules in Federal Surveys
Authors: Lambert Susan , Fugiel Peter J.
Published: July 2023

Work schedules are an important component of job quality and a critical link between work and other domains of social life. In this report, we conceptualize the core dimensions that define schedule quality (Part A); evaluate the validity of these dimensions using data from establishment and national surveys (Part B); and offer recommendations for improving measures of work schedules in four federally sponsored surveys to capture the changing nature of work schedules and track progress in reducing inequities in work schedules and job quality more broadly (Part C). With more precise data on how schedules vary, researchers will be in a better position to identify which schedule arrangements matter most for worker health, financial security, job retention, and other outcomes of interest. Such research will in turn give policy makers a clearer picture of how to target scheduling standards or other interventions for greatest impact.
The marginal adjustment of mobility tables, revisited
Authors: Macdonald Kenneth
Published: July 2023

In the study of social mobility tables, odds-ratios, because of their invariance under row and column transformations, are (with their derivatives) the tool of choice for analysing relative (as opposed to absolute) mobility. They form ‘margin insensitive measures. This non-technical note argues that row and column proportional transformations (underlying the adoption of odds-ratios) do not sustain the assumption that they preserve the structure of association within a mobility table. The case is made by careful examination of the assumptions underlying current proportional rescaling, and by considering the historical genesis of the procedure early last century. The result, by removing on of their key claimed motivators, has implications for the continuing status of odds-ratios
Macroeconomics as the Basis of Commercial Banks Stability in Nepal
Authors: Gwachha Krishna Prasad , Karmacharya Sulochana
Published: July 2023

Background:  Maintaining financial stability is vital for all financial institutions, as it fosters public trust and confidence in the entire system contributing to a healthy and well-operating economy in a country. Therefore, banks and other financial institutions must uphold their financial soundness and stability, given their crucial economic role.
Objective:  The study examines the influence of macroeconomic factors such as Inflation (INF), Gross Domestic Product (GDP) growth, Inflation Rate (INF), the Exchange rate (ER), Money Supply (M2), and NEPSE Index on bank stability of commercial banks in Nepal.
Method:  The study obtained data from the Nepal Rastra Bank, which published a quarterly economic bulletin and database on the Nepalese economy from 2001 to 2022, and applied the Autoregressive Distributed Lag (ARDL) technique for evaluation and interpretation.
Result:  The findings from this study indicate that the interest rate and money supply (M2) have a positive and significant impact on bank stability. Similarly, the NEPSE index has a positive but insignificant impact on bank stability. However, bank stability is negatively and statistically significantly impacted by both the exchange and inflation rates.
Conclusion:  The primary findings of the research indicate the presence of a sustained and stable association between bank stability and macroeconomic variables. The ARDL techniques analysis demonstrates that GDP growth, inflation, effective exchange rate, and NEPSE index are statistically significant factors, implying that they have a robust capacity to clarify the evolution of bank stability in Nepal.
Implications:  Therefore, the study suggests that policymakers and regulators need to pay close attention to macroeconomic indicators such as inflation, interest rates, money supply (M2), and exchange rates to ensure the stability and soundness of the banking system. The research also highlights the need for commercial banks to closely monitor macroeconomic developments and adjust their strategies accordingly to mitigate risks and maintain stability.

The reseach area administratively located in Budong-budong District, Mamuju Regency, West Sulawesi Province. The purpose of this study is to determine the provenance of sand sediments at Budong-budong River based on petrographic analysis of QFL (quartz, feldspar and rock fragments) components. There are seven representative samples namely HRN/BD-01, HRN/BD-02, HRN/BD-03, HRN/BD-04, HRN/BD-05, HRN/BD-06, HRN/BD-07 that will be observed by its optical properties. Based on genetic classification (Krynine, 1963, in Folk, 1980) and empirical classification (Folk, 1980) of quartz mineral grains, there are three types of quartz that can be identified; 1). Monocrystalline quartz with a sub-equant to elongated shape, dark straight to oblique waves (originally from granite and gneiss); 2). Composite polycrystalline quartz with sub-equant to elongated shape, straight dark to slanted wavy, straight and crenulated boundaries between crystals (derived from recrystallized metamorphic rocks); 3) Composite polycrystalline quartz with elongated shape, strongly wavy darkening, and straight/smooth, crenulated, and granulated inter-crystal boundaries (derived from depressed metamorphic rocks). The source rock of the reseach area based on point-counting result of quartz, feldspar and rock fragments on the Dickinson & Suczek (1979) QFL triangle diagram was interpreted as a recycled orogen type.
Effects of beam-column connection rigidities and soil-structure interaction on seismic performance of steel frames
Authors: Karakurt Meryem , Özgan Korhan
Published: July 2023

Structures can be exposed to non-linear deformations under earthquake effects. However, linear methods are mostly preferred for designs because of their simplicity and facility. The inelastic behavior of the structure is approximately taken into account by using some coefficients. However, it is possible to make more realistic and economical designs by using methods that consider the inelastic behavior of the structure. In this context, the displacement-based design method is becoming increasingly popular. This study evaluates the seismic performance of steel frames resting on elastic foundations with different beam-column joint stiffnesses using the static pushover analysis method. Static pushover curves, plastic deformations, performance points, and base shear forces were compared. The results show that the base condition greatly affects the seismic performance of the building.
Evaluation of the load-bearing wall design of Edirne Old Harbiye Barracks according to the Turkish Building Earthquake Code (TBEC-2018)
Authors: Erten Şule Yılmaz
Published: July 2023

The masonry construction system consists of stone, brick, and mortar, in which the wall element acts as the vertical load load-bearing and generally allows low-rise buildings. The buildings built with this system are mostly seen in rural areas today, but also in traditional and historical textures in city centers. Stone, brick, mortar, etc. used in the masonry construction system. The materials are materials with a low stretching rate but are resistant to pressure. In this case, against the driving force of a possible horizontal load source, the bearing walls will inevitably be damaged because they do not allow sufficient oscillation. In Türkiye, earthquake-resistant building design principles and calculation methods related to the behavior of masonry structures against earthquakes are guiding at this point. Inspecting the masonry structures planned and built in the past in terms of compliance with today's conditions and regulations is important for the sustainability of the structure. Making a building that has a negative profile in terms of compliance with the masonry construction rules is important for both the structure and the health of the user. In this study, the compliance of the load-bearing walls in the architectural design of the old Harbiye Barracks building, which is currently used by the Faculty of Architecture of Trakya University, to the rules regarding the wall design in the current regulation, Türkiye Building Earthquake Code 2018, is investigated. As a result of the study, it was seen that the building showed different suitability in different blocks. While the occupancy-to-space ratio of the b block on the bearing wall is better, it has been determined that the block does not fully comply with the rules.

Published: July 2023

This article introduces technical specifications and calculation instructions for fire resistance of uniaxial bending rectangular reinforced concrete (RC) columns under 4-side heating by standard fire. Although a number ofresearch works have been conducted following the Eurocodes to meet the long-term requirement of the country’s development in construction, it is shown that the Russian design standard SP 468.1325800.2019 (SP 468) is also applicable for concrete structures subjected to fire in the Vietnam current context. Tabulated data and simplified calculation methods according to SP 468 are introduced, followed by two practical case studies for demonstration. The calculation results show that by using the simplified calculation method the RC columns’fire-resistant limit can be explicitly determined with a particular safety factor ku, T, and a more economical design solution can be obtained compared to that of the tabulated data method. Additionally, RC columns loaded with small eccentricities exhibit greater fire resistance advantages compared to those with large-eccentricity loading. A number of other useful observations are also discussed in the latter part of this article.

Eroticism in later life is, on the whole, a taboo subject, and the stigma attached to expressions of sexual intent by older people is widespread in most cultures. However, sexuality and eroticism have an important role to play in maintaining healthy ageing. Sexuality is an essential aspect of our biology and its effects have repercussions in systems and organs other than the sexual. In this paper I review the importance of developing a sexual-erotic element in later life, an element that is intimately coupled with the phenomenon of hormesis. In hormesis, there is biological benefit following exposure to a mild stimulus or challenge, whereas exposure to a higher dose of the same stimulus becomes detrimental. Innovative sexual stimulation can be seen as a hormetic opportunity to initiate beneficial effects on the entire ageing human organism. The intention is to show that, health benefits may be obtained not only through physical (exercise), nutritional, mental or pharmacological challenges, but also through sexual stimulation of the appropriate magnitude and quality. By enhancing erotic stimulation it may be possible to experience many other benefits spanning several domains such as the endocrine, immune, circulatory and neurological. In addition, within an increasingly information-rich world, sexuality may play a part in improving adaptation to various cognitive external stimuli originating from our technological ecosystem.
Counting Processes with Multiple Randomness: Examples in Queuing Theory
Authors: Li Guang-Liang
Published: July 2023

This article introduces "counting processes with multiple randomness", which appear naturally in applications and differ essentially from known stochastic processes in the literature. Unlike times between consecutive "events" of a usual counting process, inter-event times of a counting process with multiple randomness are defined on proper subsets of the sample space, and not eligible to have marginal distributions. With examples in queuing theory, the existence of this new type of counting processes is demonstrated, and their properties are illustrated.

Cytomegalovirus (CMV) infection is with global distribution and range of 30-100%. CMV infection is the most common congenital viral infection worldwide . The sign of congenital CMV infection encountered most frequently is hearing loss, which wills 12.6% of congenitally infected newborns and congenital CMV infection form 10-20% as a cause of total hearing loss in children. About10% of the live-born infants with congenital CMV infection are symptomatic at birth. Where as an additional 10% of the infected newborns will develop permanent sequelae in the following years. Herpes simplex virus (HSV) is an abundant, enveloped, and double stranded DNA virus, belonging to the family of Herpesviridae transmitted across mucosal membranes and non intact skin, with ability to induce chronic latent infection. Susceptibility to HSV infection is associated with HLA antigens. The virus type incidence is about the same for both HSV-1 and HSV-2 strains, while HSV-2 is the most predominant in recurrent infections. HVS -1 is the common strain in labial herpetic infection, while HSV-2 is the predominant in genital infection. The site of latency is the trigeminal ganglia for labial herpetic infection and lumbosacral ganglia for genital herpetic infection. Changes in sexual behaviors of young adults may partly explain its higher incidence.
