description: In Financial Mathematics, classical Markowitz Portfolio theory provides a strategy for optimizing return on a portfolio by considering only the mean and variance of returns. However, recent theoretical and empirical studies show that it has many limitations, some of which are that it assumes a one shot allocation and Gaussianity of returns. We describe a more realistic approach which incorporates probabilities of both large gains and large losses and which is not confined to a particular type of distribution. We use a new approach in the sense that we use probabilities for the constraint and objective functions. Thus, instead of looking only at the expected return, we maximize the probability of the reward, while keeping the probability of loss small. We desire that the portfolio values a predetermined Vu and are averse to portfolio values below a predetermined value Vl. Thus, we maximize the probability of a portfolio value being above Vu subject to the constraint that the probability of portfolio value being below Vl does not exceed a given threshold ?. We introduce and verify a method to optimize the return using sequential quadratic programming. We solve the optimization problem over one period using MATLAB routine fmincon. This approach involves making certain approximations. We verify the validity of these approximations using brute force calculations. We compute the expected values of objective and constraint functions by taking the sample means of large samples generated by Monte Carlo simulations. We expand our model to multi period timeframe by first considering the two period optimization problem. We use dynamic portfolio allocation, fmincon, Monte Carlo simulations, and cubic spline interpolation so solve the optimization problem. To solve the two period problem, a grid of possible portfolio returns after the first period is used. For each of the grid values then the portfolio optimization problem over one period is solved. This then enables us to solve the overall two period problem. When the two period problem is unconstrained, our approach finds a (local) optimal solution. When constraints are introduced, our method is only suboptimal. We test our approach on different types of distributions, including the lognormal, mixture of lognormals and Pareto. While we limit ourselves to two time periods and three assets, comparisons with brute force calculations suggest that our approach using fmincon produces accurate results. Our approach has been developed in a manner that it can be applied to arbitrary number of assets as well as multiple time periods.

description: Introduction

The current adoption of the remote video conferencing approach in education often faces challenges, such as students switching off their cameras and microphones, resulting in limited engagement and participation. To address these issues, this study proposes using a digital metaverse learning space (DLS) that enables peer interactions, skill practices, and access to special materials. The aim of this study is to review the potential of implementing DLS in healthcare education. 



Summary of Methods

The 5-point Likert scale electron survey of the quantitative research study with ethical committee approval involved 166 participants from various healthcare-related fields, including medicine, pharmacy, and biomedical engineering, which gathered feedback on students' attitudes towards its development. Participants were provided with interactive questions and answers in three Anatomy DLS environments, allowing them to engage with the content. Additionally, a Poster Exhibition DLS was created, enabling students outside the course to explore ePosters prepared by the participating students. 



Summary of Results

The results highlight students' keenness to employ DLS in education, employing DLS characters with a Cronbach alpha of 0.859. More than 80% of participants showed interest in utilizing DLS occasionally or more frequently. Moreover, when given the liberty to engage, communicate, and explore the DLS setting, over 60% of participants were ready to devote their time to it frequently or consistently for those popular learning pursuits within the DLS encompassed accessing 3D objects, engaging in multiplayer games, and practising virtual skills like laboratory techniques and patient simulations.



Discussion

The findings demonstrate students' interest in engaging with DLS and highlight the value of incorporating interactive elements. The all-in-one platform enables self-revision, group collaboration, and knowledge exchange. By addressing the limitations of traditional remote video conferencing, DLS can enhance motivation by providing practical environments and promoting active participation, thus fostering effective learning.



Take-home message

The study highlights the potential of utilising DLS to drive stimulus motives in healthcare education. By leveraging the benefits of DLS, educators can enhance the quality of education and foster a more engaging and interactive learning experience for healthcare students. Future research and exploration should focus on further harnessing the capabilities of DLS and expanding its applications across various domains of education.

description: This work is devoted to the exploration of shadow cast and center of mass energy in the background of a 4-dimensional charged Gauss-Bonnet AdS black hole. On investigating particle dynamics, we have examined BH's metric function. Whereas, with the help of null geodesics, we pursue to calculate the celestial coordinates and the shadow radius of the black hole. We have made use of the hawking temperature to study the energy emission rate. Moreover, we have explored the center of mass energy and discussed its characteristics under the influence of spacetime parameters. For a better understanding, we graphically represent all of our main findings. The acquired result shows that both charge and AdS radius ($l$) decrease the shadow radius, while the Gauss-Bonnet coupling parameter $α$ increases the shadow radius in AdS spacetime. On the other hand, both $Q$ and $α$ result in diminishing the shadow radius in asymptotically flat spacetime. Finally, we investigate the energy emission rate and center of mass energy under the influence of $Q$ and $α$.

The effect of the dynamical state of clusters on gas expulsion and infant mortality

description: The star formation efficiency (SFE) of a star cluster is thought to be the critical factor in determining if the cluster can survive for a significant (>50 Myr) time. There is an often quoted critical SFE of ~30 per cent for a cluster to survive gas expulsion. I reiterate that the SFE is not the critical factor, rather it is the dynamical state of the stars (as measured by their virial ratio) immediately before gas expulsion that is the critical factor. If the stars in a star cluster are born in an even slightly cold dynamical state then the survivability of a cluster can be greatly increased.

description: Although ubiquitylation is generally assumed to regulate protein degradation via the 26S proteasome pathway, ubiquitin conjugation to transcription proteins and histones has alternative roles, such as increasing the transcriptional activity of acidic transcription activation domains (TADs). In the plant Arabidopsis thaliana the acidic transcription factor ABI3 interacts with and is regulated by many proteins, including two RING H2 ubiquitin protein ligases, ABI3 interacting protein 2 and 6 (AIP2 and AIP6). We used heterologous expression in the yeast S. cerevisiae to ascertain the functions of AIP2 and AIP6 separate from other ABI3 interacting factors present in planta. AIP2 and AIP6 bound to both the N- and C-terminal halves of ABI3, and both ubiquitylated only the N-terminal half of ABI3 that contains an acidic TAD. Although dispensable for ABI3 binding, the RING-H2 domain of AIP6 was essential for ABI3 ubiquitylation. Ubiquitin conjugation to ABI3 by either AIP2 or AIP6 triggered proteolysis via the 20S proteasome pathway. When expressed alone, the transcriptional activity of ABI3 was less than 1.5 % of the level detected in the presence of AIP6, suggesting that AIP6 could potentially regulate ABI3 activity in Arabidopsis both positively and negatively. Interestingly, AIP2 increased the activity of the ABI3-TAD to a much smaller extent.  The effect of AIP6 on ABI3 is reminiscent of the licensing of transcription factor activity by ubiquitylation that has been described in yeast and animals, and to our knowledge, it is the first report that this type of regulation operates on a plant transcription activation domain.

description: A reference interval represents a range of values that a physician can use in order to interpret a single test result from a patient. A 95% reference interval is simply the interval from the 2.5th to the 97.5th percentiles of the distribution of the test result. Since such an interval will typically depend on unknown parameters, we can use a random sample to compute an interval that will contain the reference interval with a specified confidence level. The interval so computed is referred to as a central tolerance interval. A central tolerance interval captures, with a given confidence level, a specified percentage of the central part of a univariate population. Reference regions and central tolerance regions are similarly defined for a multivariate population. This thesis considers the problem of deriving central tolerance intervals and regions for some normal populations, including multivariate normal distribution, multivariate linear regression model and the one-way and two-way random models. We also numerically investigate the computation of a simultaneous central tolerance interval for simple linear regression. Simultaneous hypotheses testing of two percentiles is a related problem of interest. The test is usually carried out using two one-sided tests which can be quite conservative. We make an attempt to derive a less conservative test by applying the bootstrap methodology. Numerical examples and real data applications are given to illustrate all of the proposed procedures.

description: Hairston, Slobodkin, and Smith (HSS) conjectured that top-down forces act on food chains with three trophic levels, which opposed the previously accepted theory that bottom-up forces dictate the dynamics of populations. HSS argued that plant life is abundant because carnivores prey upon herbivores, which prevents plants from being depleted. From this hypothesis Fretwell inferred that HSS could be applied to food chains with greater or fewer number of trophic levels. The exploitation ecosystem hypothesis (EHH) extends HSS to a food chain of any length.  According to EHH in food chains with an odd number of trophic levels plants are resource limited, which indicates bottom-up forces control the dynamics of the food chain.  Alternatively, in food chains with an even number of species plants are limited by the grazing of herbivores. Thus, for an even number of species top-down forces act on the food chain. This implies that the plant population can only increase in an odd level food chain.   Volterra extended his original model to include any number of species interacting. This simple model contained only birth/death terms and interaction terms. Using this model, Volterra proved that for an even number of species in a food chain, all species persist and remain bounded. The ecological hypotheses are supported by Volterra's work on species interaction. We will use invariant surfaces to prove Volterra's work, and also extend it to show that for an odd number of species in a food chain, unbounded orbits exist. Thus, we mathematically validate the long-debated HSS conjecture.

description: Thailand has become the first Asian country and the seventh worldwide to legalize medical and recreational cannabis use, according to the Ministry of Public Health. Despite this progress, limited data indicate that healthcare providers are generally unprepared to address the use of these substances with patients, with even less data available in Thailand and throughout Asia. This knowledge gap has impeded effective communication and treatment. As such, this study aims to explore medical students' knowledge, attitude, and the necessity of additional medical cannabis-related education.



In this -sectional research study, an online questionnaire was used to assess 180 preclinical and clinical medical students. The data was analyzed using descriptive and logistic regression.



Approximately 74.44% of surveyed medical students had only minimal knowledge about medical cannabis. Factors such as academic year of study (p <0.001), exposure to cannabis users, and sources of cannabis-related information (p <0.05) were found to be statistically significant in determining the level of medical cannabis knowledge. Notably, 82.8% of the participants emphasized the need for a comprehensive academic curriculum on medical cannabis-related topics, with academic lectures, case-based learning, and conferences being the preferred formats. Regarding attitudes towards medical cannabis, the majority (53.8%) of the students held a neutral stance. Exposure to cannabis users was found to be significantly

correlated with medical cannabis attitude.



Cannabis usage has grown in incremental favor for medical purposes globally in these past few decades. However, this study demonstrates a concerning insufficient knowledge among medical students regarding this subject. This matter can hinder the provision of standard medical care, making it imperative to prioritize the development of educational resources and collaborate with medical institutions to increase awareness about this issue. By implementing these measures, healthcare students can acquire the essential expertise to maneuver through the intricate landscape of the rapidly growing field.



Incorporating medical cannabis into medical education is of utmost importance. Furthermore, medical schools must prioritize and strengthen medical cannabis education for medical students.

description: We study the onset of spin superfluidity, namely coherent spin transport mediated by a topological spin texture, in frustrated exchange-dominated magnetic systems, engendered by an external magnetic field. We show that for typical device geometries used in nonlocal magnetotransport experiments, the magnetic field stabilizes a spin superflow against fluctuations, up to a critical current. For a given current, the critical field depends on the precessional frequency of the texture, which can be separately controlled. We contrast such dynamic stabilization of a spin superfluid to the conventional approaches based on topological stabilization.

description: In this work, we study the dispersive coupling between optical quasi-bound-states in the continuum at telecom wavelengths and GHz-mechanical modes in high-index wavelength-sized disks. We show that such cavities can display values of the optomechanical coupling rate on par with optomechanical crystal cavities ($g_{0}/2π\backsimeq$ 800 kHz). Interestingly, optomechanical coupling of optical resonances with mechanical modes at frequencies well above 10 GHz seems attainable. We also show that mechanical leakage in the substrate can be extremely reduced by placing the disk over a thin silica pedestal. Our results suggest a new route for ultra compact optomechanical cavities which can potentially be arranged in massive arrays forming optomechanical metasurfaces.
Exploring student competency and expressed learning needs using the paediatric long case examination in the final year medical students

description: Background: Long case examination is one of the most workplace competency-based assessments. It is required as a part of the national licence examinations according to the Thai Medical Council (TMC). The national standard checklist of Centre for Medical Competency Assessment comprises five domains: (1) data gathering 40% (history taking 20% & physical examination (PE) 20%), (2) communication with patients 15%, (3) case presentation, analysis, and clinical reasoning 20%, (4) patient problem-solving 15%, and (5) professional attitude and etiquette 10%. This study aimed to explore student competency and expressed learning needs of the final year medical students using the paediatric long case examination.



Summary of work: A retrospective cohort study was performed among the final medical students in the paediatric rotation in 2018-2023 at Khon Kaen Hospital, Thailand. The number of students, passing rate, case scenarios, and written feedback from the assessors were collected. The paediatric long case examination scores in five domains were reviewed. The data were analysed and reported using descriptive statistics.



Summary of results: A total of 223 of the final medical students including 134 (60%) females underwent the long case examination in paediatrics in 2018-2023. The passing rate on their first attempt was 99%. The total mean score was 84.9±10.8/100. The mean score of each domain were: (1) data gathering (history taking 17±3.5 and PE 16±4), (2) communication with patients 13.8±2, (3) case presentation, analysis, and clinical reasoning 16.6±3.9, (4) patient problem-solving 12.2±3.3, and (5) professional attitude and etiquette 9.4±1.2. The top five case scenarios were pneumonia 63 (28%), early neonatal jaundice 37 (17%), febrile convulsion 29 (13%), dengue infection 28 (13%), and acute diarrhoea 20 (9%), respectively. The most common expressed learning needs in paediatrics were how to approach and perform PE in babies and young children, and patient problem-solving including diagnostic plan, therapeutic plan, and patient education.

 

Discussion and conclusion: The paediatric long case examination has been widely used in competency-based assessment. Most students passed on their first attempt. The case scenarios were commonly seen in the real clinical practice, and tropical epidemiology in Thailand corresponded with TMC requirements for medical graduates. The most common expressed learning needs were clinical knowledge and management skill, correlated with literature review in other countries.

 

Take-home messages: Exploring student competency and expressed learning needs through a lens of paediatric long case examination scores and assessor feedback are valuable inputs for curriculum development.

description: We investigated the magnetoelastic properties of the quasi-one-dimensional spin-1/2 frustrated magnet LiCuVO$_4$. Longitudinal-magnetostriction experiments were performed at 1.5 K in high magnetic fields of up to 60 T applied along the $b$ axis, i.e., the spin-chain direction. The magnetostriction data qualitatively resemble the magnetization results, and saturate at $H_{\text{sat}} \approx 54$ T, with a relative change in sample length of $ΔL/L \approx 1.8\times10^{-4}$. Remarkably, both the magnetostriction and the magnetization evolve gradually between $H_{\text{c3}} \approx 48$ T and $H_{\text{sat}}$, indicating that the two quantities consistently detect the spin-nematic phase just below the saturation. Numerical analyses for a weakly coupled spin-chain model reveal that the observed magnetostriction can overall be understood within an exchange-striction mechanism. Small deviations found may indicate nontrivial changes in local correlations associated with the field-induced phase transitions.

description: BACKGROUND

Education research has been described as the "hardest science" of all, given the challenges of teaching and learning in environments where social interactions are central. In the health professions, we continue to support in development of basic and clinical researchers, yet the development of education researchers remains more challenging. Much of the education research in physical therapy, not unlike other health professions, has often been idiosyncratic, atheoretical, and limited to single programs or institutions. As part of a national effort to advance education research in the profession, physical therapy developed a grant writing and mentoring model, based on a successful federally funded structure, Training and Grantsmanship for Rehabilitation Research (TIGRR). This structure includes an emphasis on focused time for development of a sound research proposal under the guidance of expert mentors, discussion of complex aspects of education research, and connections with potential funding agencies.



SUMMARY OF WORK

The workshop provides guidance in developing robust and theoretically grounded programs of research, enhancing research design and conceptual and/or theoretical grounding; identifying "best-bet" funding sources; grant writing and budgeting; and creating intra-and inter­ institutional collaborative research networks and projects. The centerpiece of the workshop is one-on-one mentoring through small group sessions that provide the opportunity for participants to interact with a community of scholars (a health professions) and representatives from organizations that fund education research. The value of this workshop lies in both group and individual mentoring that provides participants with identified next steps and resources to develop their educational research.



SUMMARY OF RESULTS

The GAMER workshop results are visible for individuals and programs. Four years of participants (9-10 each year) and their record of disseminated work includes 108 papers, 162 presentations, and 42 grant submissions (22 funded). Mentees are creating learning lab groups within their departments and alumni of GAMER continue to engage with current GAMER participants.



DISCUSSION AND CONCLUSION

GAMER exceeds intended outcomes as a new initiative in physical therapy education in facilitating the development of individual scholars, creating a community of education researchers, and developing a supportive structure that inspires and advances education research.



TAKE HOME MESSAGE

The GAMER structure for mentoring education researchers can be applied a health professions.

description: We revisit the problem of pinning a reaction-diffusion front by a defect, in particular by a reaction-free region. Using collective variables for the front and numerical simulations, we compare the behaviors of a bistable and monostable front. A bistable front can be pinned as confirmed by a pinning criterion, the analysis of the time independant problem and simulations. Conversely, a monostable front can never be pinned, it gives rise to a secondary pulse past the defect and we calculate the time this pulse takes to appear. These radically different behaviors of bistable and monostable fronts raise issues for modelers in particular areas of biology, as for example, the study of tumor growth in the presence of different tissues.

description: Introduction

To enhance dissection skills of preclinical medical students, 20-30 students in CUHK were selected to join a student-oriented dissection workshop (SDW). The workshop aimed to be student-directed, and the learning outcomes were compared with the traditional dissection lessons.



Summary of Methods

Students chose a body region from a silent teacher[1] for designing and dissecting specimen. There were no checklist nor strict guidelines for students, and they were allowed to design the specimen and explored the anatomical details on their own. Teachers took the role of advisor instead of instructing students’ work.



Summary of Results

A post-workshop survey was conducted to reveal the outcomes of SDW. With a scale of 1-5 (5: Most agreed), all participants scored 4-5 in terms of whether SDW improved their detailed anatomical understanding, understanding gross pathology of silent teacher and appreciating variations. Students also strongly agreed SDW provided a self-directed learning environment, rendering them to enhance critical thinking and problem-solving skills. However, the results in traditional dissection lessons varied among students and generally showed a lower score in the corresponding aspects.



Discussion

Preclinical medical education had been more unidirectional among higher education. Students rely on lectures and textbooks, with very limited chance to interact with teachers and more importantly, the anatomical structures. Unlike a spoon-feeding module, SDW was student-directed and allowed freedom to design specimen. Positive responses from participants revealed a free, active learning environment could enhance anatomical understanding and offered more hands-on experience.

SDW provides opportunities for trial and error. Seldom do medical education encourage students to make mistake. This hinders eagerness of students to attempt and voice out their ideas. This situation had already been shown in many preclinical tutorials, that students were unlikely to answer questions or raised their ideas. Nonetheless, SDW allowed students to practice their dissection and suturing skills on body parts of silent teachers that were not planned to be a specimen. This allowed students to explore more contents and skills, for instance, tracing and isolating neurovascular structures, pathology, and variations of silent teacher. This in turn facilitated their learning motivation.

Trimethylaluminum Diffusion in PMMA Thin Films during Sequential Infiltration Synthesis: In Situ Dynamic Spectroscopic Ellipsometric Investigation

description: Sequential infiltration synthesis (SIS) provides a successful route to grow inorganic materials into polymeric films by penetrating of gaseous precursors into the polymer, both in order to enhance the functional properties of the polymer creating an organic-inorganic hybrid material, and to fabricate inorganic nanostructures when infiltrating in patterned polymer films or in selfassembled block copolymers. A SIS process consists in a controlled sequence of metal organic precursor and co-reactant vapor exposure cycles of the polymer films in an atomic layer deposition (ALD) reactor. In this work, we present a study of the SIS process of alumina using trimethylaluminum (TMA) and H2O in various polymer films using in situ dynamic spectroscopic ellipsometry (SE). In situ dynamic SE enables time-resolved monitoring of the swelling of the polymer, which is relevant to the diffusion and retain of the metal precursor into the polymer itself. Different swelling behaviour of poly(methylmethacrylate) (PMMA) and polystyrene (PS) was observed when exposed to TMA vapor. PMMA films swell more significantly than PS films do, resulting in very different infiltrated Al2O3 thickness after polymer removal in O2 plasma. PMMA films reach different swollen states upon TMA exposure and reaction with H2O, depending on the TMA dose and on the purge duration after TMA exposure, which correspond to different amounts of metal precursor retained inside the polymer and converted to alumina. Diffusion coefficients of TMA in PMMA were extracted investigating the swelling of pristine PMMA films during TMA infiltration and shown to be dependent on polymer molecular weight. In situ dynamic SE monitoring allows to control the SIS process tuning it from an ALD-like process for long purge to a chemical vapour deposition - like process selectively confined inside the polymer films
Apprenticeship at work: the case of cooking apprenticeship at Earl’s Restaurants

description: Apprenticeship is an old and venerable method of teaching skills and knowledge stretching back to antiquity. Most of the traditional aspects of this teaching and learning method, the practice of apprenticeship, takes place in the workplace where few educational researchers venture. In addition, because apprenticeship bridges issues related to education, training, labour market, social policy, and anthropology, research reports cover a broad spectrum but do not offer a synthetic view of apprenticeship. This research, focuses on a single trade, in a single company, in order to document the practice of formal apprenticeship. To set the stage, a preliminary classification of the disparate literature on apprenticeship as well as a brief history of apprenticeship in Canada and in British Columbia is offered. The registered cook apprenticeship in British Columbia studied shows that four major themes undergird the 'program': context, progression, knowledge, and vocational training. Context directly affects what can and is practiced on the job, hence affects the outcomes of the apprenticeship. In addition, it can be assumed that micro contextual differences play a role as important as macro contextual differences in apprenticeship. Progression represents the journey from neophyte to master and impacts apprenticeship as it charts one's career progression; a clear view of progression also seems to affect apprenticeship outcomes. Knowledge and vocational education seem to be linked and represent, for the apprentices and the masters, external yardsticks of achievement which are used to confirm stages of the journey. The research shows that present day apprenticeships have retained much of their rich tradition. Historical elements can be recognized in the models which summarize writings about apprenticeship presented in this paper. The models help contrast the practice with the intent of apprenticeship; and allow for the creation of a composite model which best fits fit a real-life case. Suggestions about the current practice of apprenticeship can be made from the models. But future research will have to further clarify some of the issues raised here, as well as chart a coherent course for the study of apprenticeship.

description: A modified mapping review was done to describe the status of HPEd programs in the Philippines and to present a working roadmap for the future of HPEd in the country.  3 data collection methods were conducted: 1) Web search yielding 13 HPEd programs, mostly at the Master’s level: 2)  KIIs, revealing four themes: (a) Upskilling educators towards improving health care outcomes; (b) Coping with changes in HPEd landscape through ICT, resource optimization, and inter-institutional collaborations and partnerships; (c) Concretizing transformative HPEd; and (d) Challenges of employing full time faculty members and attracting students who persevere towards program completion; and 3) Roadmapping workshop which provided the direction for HPEd: enhancing and future-proofing the curriculum and forming partnerships and collaborations to mold health professionals to be responsive and relevant to the current health care delivery needs.

HPEd programs in the Philippines are established and spread throughout but share a common purpose. There are gaps and challenges, but the roadmap envisions HPEd as a liberative, future-proofed and organized discipline producing effective teachers, leaders, managers, and promoters of public health who, through a nationwide organization of HPEd practitioners, collaborate to promote and develop HPEd in the country.

description: We investigate Laughlin's fractional quantum Hall effect wave function in the cylinder geometry of Laughlin's integer quantum Hall effect argument, at filling factor 1/3. We show that the plasma analogy leads to a periodic density, and that the wave function admits a representation as a ``quantum polymer'', reminiscent of the quantum dimer model by Rokhsar and Kivelson. We explain how the representation can be exploited to compute the normalization and one-particle density in the limit of infinitely many particles.
