Performance Analysis of a Philippine REIT and Its Optimal Allocation in a Mixed-asset Portfolio

Real estate investment trusts (REIT) are new and potentially lucrative investment vehicles in the Philippines with their inherent risks and rewards. Understanding their behavior and characteristics allows investors to maximize their profits and mitigate their risks. This study specifically considers the Ayala REIT (AREIT) and aims to conduct a performance analysis on it. The study used daily closing quotes of AREIT, Philippine Stock Exchange index and sectoral indices, S&P Philippine bond index, and monthly Philippine treasury bill from August 2020–April 2021. By using established methods in the modern portfolio theory (MPT), the risk- adjusted returns of the AREIT were obtained and compared with those of other assets. Other descriptors, such as correlations that indicate diversification potential were also obtained. This research also extends beyond performance and comparative analyses by using the mean-variance framework to determine the efficient frontiers that highlight the opportunity set of portfolios with the best return for a given level of risk. As a final modification in our AREIT description, this study employed the utility theory to incorporate an investor’s risk appetite in determining the optimal allocation of AREIT. The results show that AREIT had high returns and low risk relative to the other assets considered, as well as low to negative correlations with these assets. Moreover, it was observed that optimal AREIT weight increased with risk-aversion. AREIT played a dual role in increasing yields and mitigating risks in the portfolios considered.
$\mathcal L$-invariant for Siegel-Hilbert forms

We prove in some cases a formula for the Greenberg-Benois $\mathcal{L}$-invariant of the spin, standard and adjoint Galois representations associated with Siegel-Hilbert modular forms. In order to simplify the calculation, we give a new definition of the $\mathcal{L}$-invariant for a Galois representation $V$ of a number field $F\neq \mathbb{Q}$; we also check that it is compatible with Benois' definition for $\mathrm{Ind}_F^{\mathbb{Q}}(V)$.
Evaluation of Cardiac Biomarkers and Expression Analysis of IL-1, IL-6, IL-10, IL-17, and IL-25 among COVID-19 Patients from Pakistan

Coronavirus disease 19 (COVID-19) is caused by viral infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Where upregulation of several important biomarkers and multiple organ dysfunction occurs, this study aimed to evaluate the association of cardiac biomarkers and CS induced acute lung damage with disease severity and mortality in survival of COVID-19 patients. A total of 500 COVID-19 patients with elevated cardiac biomarkers were studied for the analysis of myocardial abnormality through cardiac enzymes, inflammatory biomarkers, and the expression analysis of various cytokines, including IL-1, IL-6, IL-10, IL-17, and IL-25 genes. The elevation of various cardiac enzymes including LDH (87%), CK (78.4%), TNI (80.4%), CK-MB (83%), and D-dimer (80.8%) were found correlated (p < 0.001) with COVID-19 infection. Cardiac enzyme elevation was highly associated with an increased level of inflammatory biomarkers such as CRP (14.2%), SAA (11.4%) and erythrocyte sedimentation rate (ESR) (7.8%) (p = 0.001 for all). The quantitative expression analysis of IL-10, 1L-17, and 1L-25 were found to be high, while those of IL-1 and IL-6 were moderately elevated. The death-to-live ratio of COVID-19 patients was 457:43 indicating that the patients having elevated levels of both CKMB, D-dimer, CK and IL-1, IL-6, IL-10 and D-dimer, Troponin, CK and IL-1, IL-10 had high fatality rate (73% and 12% respectively). The current finding concludes that the evaluation of cardiac biomarkers with cytokine storm plays a significant role in COVID-19-associated anatomical organ damage, myocardial injury, and mortality. Physicians should pay special attention to cardiac biomarkers in patients with old age, inflammation, and comorbidities among COVID-19 infections.
Overview of quarkonia and heavy flavour measurements by CMS

This writeup summarizes recent CMS results on quarkonia measurements in pp, pPb and PbPb collisions at LHC. The excellent muon detection capability of CMS allows measurement of charmonia states at high transverse momentum ($p_T$) while the $\Upsilon$ states can be reconstructed starting at zero $p_T$. The absolute and relative yields of different charmonia and bottomonia states modified in PbPb collisions (over pp collisions) are described. The vertexing capability of CMS enables measurement of B meson energy loss via its decay to J/$\psi$. An overview of these measurements is given. How these measurements compare with other experiments at RHIC and LHC and have improved the understanding of heavy ion collisions has been discussed.
YouTube: Is It a Reliable Source of Nutrition Information on COVID-19 Pandemic?

Data on the nutrition-related misinformation about COVID-19 are limited. This study analysed the quality and accuracy of the nutrition information available on YouTube about current COVID-19 pandemic as well as assessed the content of the videos. YouTube was searched using the terms “nutrition and COVID-19” in Turkish on 1 February 2021. Videos were filtered according to relevancy, and the first 280 videos were analysed. A total of 218 videos were reviewed and classified as “misleading” or “relevant” depending on the information provided. The transparency, utility, reliability, and accuracy of video contents were assessed. The videos attracted a cumulative 6,258,694 views. There were 178 (81.7%) fully relevant and 40 (18.3%) misleading videos. Approximately 80% of the videos shared by health professionals were relevant videos. Government organisations only shared relevant videos. Relevant videos had higher reliability, accuracy, and quality than misleading videos. The nutrition-related content of COVID-19 videos is suboptimal on YouTube. As the COVID-19 pandemic worsens, and nutrition could improve immunity, health professionals and educational and government organisations need to engage more in the spread of nutrition-related COVID-19 information to Internet platforms based on nutrition guidelines and the latest scientific evidence. This will be a practical and immediately implementable public health strategy to effectively spread the right information.
Association of Depression and Anxiety With Hypertensive Crisis: A Cross-Sectional Study From a Hospital Setting in Karachi, Pakistan

Objective: Hypertension, a leading risk factor for cardiovascular death has been closely linked with depression and anxiety. The aim of this study was to examine the association of depression or anxiety with hypertensive crisis in patients from a hospital setting and also see if the association is affected by age groups or gender. Design and method: This cross-sectional study was conducted between July 2019 and March 2022 on 290 patients admitted at the Aga Khan University Hospital (AKUH). All adult patients of more than 18 years of age admitted with uncontrolled hypertension with systolic blood pressure of > 140 and diastolic blood pressure > 90 admitted through emergency were included. Hypertensive crisis was defined as systolic blood pressure more than 180mm Hg or a diastolic blood pressure more than or equal to 120mm Hg, with or without accompanying end organ damage. Depression and Anxiety were evaluated using the Hospital Anxiety and Depression Scale (HADS), with a cut-off score of greater than 8. Results: Of the patients identified with uncontrolled hypertension, a total of 140 (48.3 percent) of the patients presented with a hypertensive crisis, while 150 (51.3 percent) did not have a hypertensive crisis at presentation. In the hypertensive crisis group, 60 (49. percent) had HADS scores consistent with depression, while 83 (59.3 percent) had HADS scores consistent with anxiety. In patients with hypertensive crisis, HADS depression and anxiety were most prevalent in the 61-75 age group (39.7 percent). In the comparison of gender, it was found that males and females with hypertensive crisis had an almost equal prevalence of anxiety (49.4 percent in males versus 50.6 percent in females). A slightly higher prevalence of depression was seen in females with hypertensive crises when compared to males. Conclusions: We found no association between depression or anxiety with hypertensive crisis, and the association is not affected by age group or gender. However, do note that half of the patients with hypertensive crises had depression or anxiety. Future large multicentered studies are required to study the link in greater detail.
X-RAY SCALING RELATION IN EARLY-TYPE GALAXIES: DARK MATTER AS A PRIMARY FACTOR IN RETAINING HOT GAS

We have revisited the X-ray scaling relations of early-type galaxies (ETG) by investigating, for the first time, the LX,Gas–MTotal relation in a sample of 14 ETGs. In contrast to the large scatter (a factor of 102–103) in the LX,Total–LB relation, we found a tight correlation between these physically motivated quantities with an rms deviation of a factor of three in LX,Gas = 1038–1043 erg s−1 or MTotal = a few × 1010 to a few × 1012 M☉. More striking, this relation becomes even tighter with an rms deviation of a factor of 1.3 among the gas-rich galaxies (with LX,Gas > 1040 erg s−1). In a simple power-law form, the new relation is (LX,Gas/1040 erg s−1) = (MTotal/3.2 × 1011 M☉)3. This relation is also consistent with the steep relation between the gas luminosity and temperature, LX,Gas ∼ TGas4.5, identified by Boroson et al., if the gas is virialized. Our results indicate that the total mass of an ETG is the primary factor in regulating the amount of hot gas. Among the gas-poor galaxies (with LX,Gas < a few × 1039 erg s−1), the scatter in the LX,Gas–MTotal (and LX,Gas–TGas) relation increases, suggesting that secondary factors (e.g., rotation, flattening, star formation history, cold gas, environment, etc.) may become important.
Host galaxies of long gamma-ray bursts in the Millennium Simulation

In this work, we investigate the nature of the host galaxies of long Gamma-Ray bursts (LGRBs) using a galaxy catalogue constructed from the Millennium Simulation. We developed a LGRB synthetic model based on the hypothesis that these events originate at the end of the life of massive stars following the collapsar model, with the possibility of including a constraint on the metallicity of the progenitor star. A complete observability pipeline was designed to calculate a probability estimation for a galaxy to be observationally identified as a host for LGRBs detected by present observational facililties. This new tool allows us to build an observable host galaxy catalogue which is required to reproduce the current stellar mass distribution of observed hosts. This observability pipeline predicts that the minimum mass for the progenitor stars should
Study on influence of geometric characteristics of cracks on HAM coupling transfer and thermal performance of multi-layer cellular concrete wall

The effect of concrete cracks on the evaluation of the thermal performance of walls has not been effectively considered within the assessment of the thermal and hygroscopic performance of buildings. Based on the dual permeability model, a conjugate method is proposed to reconstruct the PDE equation of unsaturated porous materials with cracks. The reliability of the model is verified from three angles: the heat-moisture coupling benchmark of matrix material, the analytical solution of two-dimensional single fracture heat flow coupling problem and the moisture absorption problem of unsaturated cracks. The reliability of the model is verified from three perspectives: the benchmark of thermal and hygroscopic coupling of matrix materials, the analytical solution to the two-dimensional single-break thermal flow coupling problem, and the hygroscopic problem of unsaturated cracks. The effect of heat and moisture transfer in cracked concrete was quantified by detailed modeling of cracks in terms of the probability of over-penetration, crack roughness, crack density, length, and angle of a two-dimensional discrete crack network, showing that cracks contribute to moisture transfer. This is followed by a 10 day experimental simulation of the meteorological environment, comparing the quantities of moisture accumulation, thermal performance, internal surface temperature and humidity within the fractured and non-fractured wall structures, illustrating the potential adverse effects of cracks on thermal performance and moisture transfer in walls under characteristic conditions. Finally, the necessity of applying moisture-proof layer to the damaged wall is demonstrated by comparing the results before and after the application of the moisture-proof layer.
An Extensive Photometric Investigation of the W UMa System DK Cyg

DK Cyg is a contact binary system that undergoes complete eclipses. All the published photoelectric data have been collected and utilized to reexamine and update the period behavior of the system. A significant period increase with rate of 12.590 × 10−11 days/cycle was calculated. New period and ephemeris have been calculated for the system. A long term photometric solution study was performed and a light curve elements were calculated. We investigated the evolutionary status of the system using theoretical evolutionary models.
EXCESS LIFETIME AND HEREDITARY CANCER RISK DUE TO NATURAL RADIOACTIVITY IN SOME TYPES OF SPICES SAMPLES IN IRAQI MARKETS

In present study, natural radioactivity of 238U, 232Th, and 40K in selected samples of spices existing in the Iraqi market were estimated using gamma-ray spectroscopy with NaI(Tl). Also, it was determined some radiological risks parameters such as, radium equivalent (Raeq) and internal hazard index (Hin) in the present study. The results show that, the average value of specific activity for of 238U, 232Th, and 40K were 10.63±1.15 Bq.kg-1, 9.82± 0.67 Bq.kg-1 and 243.28±5.65 Bq.kg-1 respectively. While, the average value of Raeq and Hin were 43.35 Bq.kg-1and 0.144, respectively. The average value of AED total in the samples under study were 0.011 mSv/y which it is lower than acceptable limit according to UNSCEAR (2008). The results of natural radionuclides and radiological risks parameters in most the spices samples were far below the accepted of the world limit. Therefore, it can be concluded that spices samples may be used for eating without any health effects.
Vindicating single-T modified blackbody fits to Herschel SEDs

I show here that the bulk of the dust mass in a galaxy can be equivalently estimated from i) the full spectral energy distribution of dust emission, using the approach of Draine & Li (2007, ApJ, 657, 810) that includes a distribution of dust grains and a range of interstellar radiation field intensities; ii) the emission in the wavelength range 100 μm ≤ λ ≤ 500 μm (covered by the Herschel Space Observatory), by fitting a simpler single-temperature modified blackbody to the data. Recent claims to the contrary should be interpreted as a caveat in the simpler fits to use an absorption cross section which is consistent both in the normalization and in the spectral index β with that of the full dust model. I also show that the dust mass does not depend significantly on the choice of β, if both the dust mass and the absorption cross section are derived with the same assumption on β.
Negative caregiving and stress reactivity moderate the relation between early life stress and externalizing in adolescence.

Exposure to early life stress (ELS) is common and has been implicated in the development of psychopathology; importantly, however, many individuals who experience ELS do not develop emotional or behavioral difficulties. Prior research implicates stress exposure, negative caregiving behaviors, and patterns of physiological reactivity in predicting psychological well-being; however, the precise factors that contribute to resilience versus vulnerability to the adverse effects of stress exposures are not well understood. In a longitudinal study of adolescents (N = 120) assessed at three timepoints approximately every 2 years beginning at the ages of 913 years, we examined the roles of autonomic reactivity to social stress (assessed through skin conductance during the Trier Social Stress Task) and negative caregiving behaviors as moderators of the association between exposure to ELS and internalizing and externalizing symptoms. We found that the relation between ELS and externalizing symptoms was moderated by both negative caregiving and autonomic reactivity, such that the relation between ELS and externalizing was positive at low levels of negative caregiving and at high levels of autonomic reactivity; interactions predicting internalizing symptoms were not statistically significant. These findings highlight the importance of considering physiological and environmental variables that might contribute to susceptibility or resilience to symptoms of psychopathology following exposure to ELS.
Symmetry-adapted Wannier functions in the maximal localization procedure

A procedure to construct symmetry-adapted Wannier functions in the framework of the maximally localized Wannier function approach [Marzari and Vanderbilt, Phys. Rev. B 56, 12847 (1997); Souza, Marzari, and Vanderbilt, ibid. 65, 035109 (2001)] is presented. In this scheme, the minimization of the spread functional of the Wannier functions is performed with constraints that are derived from symmetry properties of the specified set of the Wannier functions and the Bloch functions used to construct them, therefore one can obtain a solution that does not necessarily yield the global minimum of the spread functional. As a test of this approach, results of atom-centered Wannier functions for GaAs and Cu are presented.
Diffusion, thermalization, and optical pumping of YbF molecules in a cold buffer-gas cell

We produce YbF molecules with a density of 10{sup 18} m{sup -3} using laser ablation inside a cryogenically cooled cell filled with a helium buffer gas. Using absorption imaging and absorption spectroscopy we study the formation, diffusion, thermalization, and optical pumping of the molecules. The absorption images show an initial rapid expansion of molecules away from the ablation target followed by a much slower diffusion to the cell walls. We study how the time constant for diffusion depends on the helium density and temperature and obtain values for the YbF-He diffusion cross section at two different temperatures. We measure the translational and rotational temperatures of the molecules as a function of time since formation, obtain the characteristic time constant for the molecules to thermalize with the cell walls, and elucidate the process responsible for limiting this thermalization rate. Finally, we make a detailed study of how the absorption of the probe laser saturates as its intensity increases, showing that the saturation intensity is proportional to the helium density. We use this to estimate collision rates and the density of molecules in the cell.
A LUMINOUS AND FAST-EXPANDING TYPE Ib SUPERNOVA SN 2012au

We present a set of photometric and spectroscopic observations of a bright Type Ib supernova SN 2012au from −6 days until ∼ + 150 days after maximum. The shape of its early R-band light curve is similar to that of an average Type Ib/c supernova. The peak absolute magnitude is MR = −18.7 ± 0.2 mag, which suggests that this supernova belongs to a very luminous group among Type Ib supernovae. The line velocity of He i λ5876 is about 15,000 km s−1 around maximum, which is much faster than that in a typical Type Ib supernova. From the quasi-bolometric peak luminosity of (6.7 ± 1.3) × 1042 erg s−1, we estimate the 56Ni mass produced during the explosion as ∼0.30 M☉. We also give a rough constraint to the ejecta mass 5–7 M☉ and the kinetic energy (7–18) × 1051 erg. We find a weak correlation between the peak absolute magnitude and He i velocity among Type Ib SNe. The similarities to SN 1998bw in the density structure inferred from the light-curve model as well as the large peak bolometric luminosity suggest that SN 2012au had properties similar to energetic Type Ic supernovae.
Superconductivity at 6 K and the Violation of Pauli Limit in Ta2PdxS5

We discovered that Ta2PdxS5 (\(x \lesssim 1.0\)) shows superconductivity at Tc ∼ 6 K. The temperature dependent resistivity of single crystalline Ta2Pd0.92S5 indicated that the system is close to Anderson localized state associated with strong disordering due to Pd deficiency. The dirty limit superconductivity as well as the temperature dependence of specific heat C(T) implies gapful s-wave superconductivity. The upper critical field µ0Hc2 in the T = 0 K limit with the magnetic field parallel to the TaS6 chains was found to be as high as 31 T, exceeding the Pauli paramagnetic limit µ0HP = 10.2 T by a factor of 3. We argue that the absence of the paramagnetic pair-breaking originates from strong spin–orbit scattering due to Pd deficiencies embedded in the periodic lattice of heavy 5d Ta and 4d Pd.
Designing Mobile Education for Postgraduate Human Resource Management Courses

The postgraduate programs in human resource management at PGRI University Semarang include only the teaching materials provided by the lecturer. No form of media is used to improve students’ learning interests. Thus, this study explores a mixed reality-based educational mobile application that enables students to see the real world based on virtual and augmented realities, displaying information in 3D to ultimately increase their motivation and learning outcomes. The current research uses the R&D model ADDIE (Analysis, Design, Develop, Disseminate). In their first year of research, the authors have developed a mobile education product based on mixed reality for the postgraduate human resources management course. The product has been validated by a material expert with an average score of 93 and a media expert with an average score of 92. This shows that a mobile education product is effective in improving students’ learning interests and outcomes. Keywords: design, educational games, courses, education human resource management
Linking Measure of the Tropical Stingless Bee (Apidae, Meliponini, and Heterotrigona itama) Honey Quality with Hives Distance to the Source of Heavy Metal Pollution in Urban and Industrial Areas in Sabah, Borneo

Honey is a natural product of bees, and its chemical composition depends on the nectar sources of the surrounding flora as well as environmental factors. However, keeping hives in areas polluted with heavy metals can affect the quality of bee products such as honey. To date, there have been very few studies on the health risks of consuming honey at various locations in the Malaysian state of Sabah, Borneo, in relation to food standards and heavy metal contamination of honey from the stingless bee, Heterotrigona itama in association with pollutant sources. A total of 63 samples of raw and unprocessed honey were collected directly from beekeepers producing honey at five sites in the industrial areas. All selected heavy metals were measured using an inductively coupled plasma optical emission spectrophotometer (ICP-OES). Overall, the most frequently detected element was Zn (0.090 mg/kg), followed by Pb (0.012 mg/kg), As (0.004 mg/kg), and Cr (0.003 mg/kg), while Cd (0.001 mg/kg) was the lowest element in honey from all areas. With the exception of Cr and Zn, a significant correlation was found between PCA factor score 1 and heavy metal concentration in honey for Pb, Cd, and As, suggesting that the source of pollution for these metal elements was from hives closer to major roads, cities/town, petrochemical hub, and power plants. Although the heavy metal concentrations in the honey samples did not exceed the food standard limits and therefore do not pose a health risk, the observed increase in heavy metal concentrations in honey in industrial areas could pose a potential risk in the future due to the growing interest in rearing of stingless bees for honey production in these areas of Sabah.
