Lee Kong Chian School Of Business Year In Review 2021-2022, Singapore Management University

SMU Corporate Reports

As Singapore and the world reopens, this has led to changes, especially as people feel safe to travel abroad again. This has impacted us of course. We have seen an 8.9 percent drop in undergraduate applications from our 2022 high. This decline is due in no small part to the relaxation of travel restrictions. However, despite the drop, the quality of applications this year is similar or maybe even slightly better than the year before. In the end, we matriculated 884 students, above our target. This includes 38 scholarship recipients who accepted our offer, representing a record yield. We have …

Faculty too were able to attend academic conferences and meet with educational partners, business connections and research associates …

Immersive Inoculation: Testing If Architecture Can Become A Form Of Emotional Supplementation, Julia Kazubowsi, Chloe De Marco

Architecture Thesis Prep

The environments, objects, and spaces we encounter rub off on us, even if we don't notice. Like a human interaction, every inanimate encounter we have have with surrounding objects and architecture has a positive or negative affect on us.

We recognize that ordinary things have a surprising power to create extraordinary feelings and reactions. This thesis propose a visual medium that bridges the gap between us and the inanimate. Where we meet in the middle is an architectural experience that is emotionally charged, introducing specific emotions to the body. Just as movies, books, and happy pills elicit a response from …

Eternal Imprint: Two Libraries Linked In Time, Jaifer Sultan

Architecture Thesis Prep

The thesis is an exploration of the symbolic relationship between Earth and the Moon through the conceptualization of two libraries, one on Earth and one on the Moon, are to be formally expressed through a mitosis-like interdependency, where both libraries are in constant architectural dialogue with each other despite their separation which occurred some time ago.

The thesis positions itself in the architectural discourse through the rigorous stud and analysis of the library typology throughout history, to both symbolize meaning and ritualize one's experience of acquiring knowledge. This understanding of the library typology will be tackled through the cataloging of …

Lex Orandi, Lex Credendi: Eschatological Teachings In The Prayers Of A Funeral Mass, Carolyn Lewis

Aristos

In light of twenty-first century secularization, and with the liturgical revisions following the Second Vatican Council, some lament that the true eschatological doctrines of the Catholic faith are no longer evident in the Funeral Mass. This would then miscarry the axiom Lex Orandi, Lex Credendi, exposing significant shortcomings within these liturgical revisions. This paper analyses the propers of the Funeral Mass, in order to assess which eschatological teachings are evident in those prayers. Examined first are the Christocentric salvific teachings, considering the hopeful Paschal focus of the Funeral Mass. Representations of the nature of the afterlife are then analysed, …

What Roles Do Reason And Revelation Play In The Knowledge Of The Trinity, According To St Thomas Aquinas?, Matthew Anslow

Aristos

The Holy Trinity is viewed, within the Catholic tradition, as “the central mystery of the Christian faith and life.” Given the importance of the doctrine, this paper explores to what extent, and by what means, humans are capable of knowledge of the Trinity. It summarises Thomas Aquinas’ account of the knowledge of the Trinity, beginning with an outline of Aquinas’ understanding of the place of revelation and reason in the knowledge of God in general. From there, the paper notes Aquinas’ denial of the ability of human reason to discern the Trinity before turning to his primary reason for this …

Lifestyle Interventions For Prevention And Management Of Diet-Linked Non-Communicable Diseases Among Adults In Arab Countries, Maryam Naveed Muhammad Tariq, Lily Stojanovska, Ayesha S. Al Dhaheri, Leila Cheikh Ismail, Vasso Apostolopoulos, Habiba I. Ali

CoMHS Faculty Work

The increased incidences of diet-related non-communicable diseases (NCDs) such as diabetes, obesity, and cardiovascular diseases among adults are becoming the chief public health concern in most Arab countries. Economic expansion has contributed to a nutrition shift from a traditional seasonal diet to Westernized eating habits coupled with a sedentary lifestyle. Despite the rising concern for NCD mortality, public health policies are inadequately addressed. This narrative review aims to discuss the effectiveness of nutritional interventions focusing on diet and physical activity in the management of NCDs among Arab adults. A comprehensive literature search was performed using different database platforms such as …

Bioassay-Guided Fractionation With Antimalarial And Antimicrobial Activities Of Paeonia Officinalis, Mamdouh Nabil Samy, Basma Khalaf Mahmoud, Nourhan Hisham Shady, Usama Ramadan Abdelmohsen

Faculty and Student Publications

Bioassay-guided fractionation technique of roots of Paeonia officinalis led to isolation and structure elucidation of seven known compounds, including four monoterpene glycosides: lactiflorin (1), paeoniflorin (4), galloyl paeoniflorin (5), and (Z)-(1S,5R)-β-pinen-10-yl β-vicianoside (7); two phenolics: benzoic acid (2) and methyl gallate (3); and one sterol glycoside: β-sitosterol 3-O-β-D-glucopyranoside (6). The different fractions and the isolated compounds were evaluated for their antimicrobial and antimalarial activities. Fraction II and III showed antifungal activity against Candida neoformans with IC50 values of 28.11 and 74.37 µg/mL, respectively, compared with the standard fluconazole (IC50 = 4.68 µg/mL), and antibacterial potential against Pseudomonas aeruginosa (IC50 = …

Discovery Of A Lectin Domain That Regulates Enzyme Activity In Mouse N-Acetylglucosaminyltransferase-Iva (Mgat4a), Masamichi Nagae, Tetsuya Hirata, Hiroaki Tateno, Sushil K. Mishra

Faculty and Student Publications

N-Glycosylation is a common post-translational modification, and the number of GlcNAc branches in N-glycans impacts glycoprotein functions. N-Acetylglucosaminyltransferase-IVa (GnT-IVa, also designated as MGAT4A) forms a β1-4 GlcNAc branch on the α1-3 mannose arm in N-glycans. Downregulation or loss of GnT-IVa causes diabetic phenotypes by dysregulating glucose transporter-2 in pancreatic β-cells. Despite the physiological importance of GnT-IVa, its structure and catalytic mechanism are poorly understood. Here, we identify the lectin domain in mouse GnT-IVa’s C-terminal region. The crystal structure of the lectin domain shows structural similarity to a bacterial GlcNAc-binding lectin. Comprehensive glycan binding assay using 157 glycans and solution NMR …

Validated Determination Of Nrg1 Ig-Like Domain Structure By Mass Spectrometry Coupled With Computational Modeling, Niloofar Abolhasani Khaje, Alexander Eletsky, Sarah E. Biehn, Charles K. Mobley

Faculty and Student Publications

High resolution hydroxyl radical protein footprinting (HR-HRPF) is a mass spectrometry-based method that measures the solvent exposure of multiple amino acids in a single experiment, offering constraints for experimentally informed computational modeling. HR-HRPF-based modeling has previously been used to accurately model the structure of proteins of known structure, but the technique has never been used to determine the structure of a protein of unknown structure. Here, we present the use of HR-HRPF-based modeling to determine the structure of the Ig-like domain of NRG1, a protein with no close homolog of known structure. Independent determination of the protein structure by both …

A Distinct Mechanism Of C-Type Inactivation In The Kv-Like Kcsa Mutant E71v, Ahmed Rohaim, Bram J. A. Vermeulen, Jing Li, Felix Kümmerer

Faculty and Student Publications

C-type inactivation is of great physiological importance in voltage-activated K+ channels (Kv), but its structural basis remains unresolved. Knowledge about C-type inactivation has been largely deduced from the bacterial K+ channel KcsA, whose selectivity filter constricts under inactivating conditions. However, the filter is highly sensitive to its molecular environment, which is different in Kv channels than in KcsA. In particular, a glutamic acid residue at position 71 along the pore helix in KcsA is substituted by a valine conserved in most Kv channels, suggesting that this side chain is a molecular determinant of function. Here, a combination of X-ray crystallography, …

Supervised Acoustic Embeddings And Their Transferability Across Languages, Sreepratha Ram, Hanan Aldarmaki

Natural Language Processing Faculty Publications

In speech recognition, it is essential to model the phonetic content of the input signal while discarding irrelevant factors such as speaker variations and noise, which is challenging in low-resource settings. Self-supervised pretraining has been proposed as a way to improve both supervised and unsupervised speech recognition, including frame-level feature representations and Acoustic Word Embeddings (AWE) for variable-length segments. However, self-supervised models alone cannot learn perfect separation of the linguistic content as they are trained to optimize indirect objectives. In this work, we experiment with different pre-trained self-supervised features as input to AWE models and show that they work best …

(R1500) Type-I Generalized Spherical Interval Valued Fuzzy Soft Sets In Medical Diagnosis For Decision Making, M. Palanikumar, K. Arulmozhi

Applications and Applied Mathematics: An International Journal (AAM)

In the present communication, we introduce the concept of Type-I generalized spherical interval valued fuzzy soft set and define some operations. It is a generalization of the interval valued fuzzy soft set and the spherical fuzzy soft set. The spherical interval valued fuzzy soft set theory satisfies the condition that the sum of its degrees of positive, neutral, and negative membership does not exceed unity and that these parameters are assigned independently. We also propose an algorithm to solve the decision making problem based on a Type-I generalized soft set model. We introduce a similarity measure based on the Type-I …

(R1971) Analysis Of Feedback Queueing Model With Differentiated Vacations Under Classical Retrial Policy, Poonam Gupta, Naveen Kumar, Rajni Gupta

Applications and Applied Mathematics: An International Journal (AAM)

This paper analyzes an M/M/1 retrial queue under differentiated vacations and Bernoulli feedback policy. On receiving the service, if the customer is not satisfied, then he may join the retrial group again with some probability and demand for service or may leave the system with the complementary probability. Using the probability generating functions technique, the steady-state solutions of the system are obtained. Furthermore, we have obtained some of the important performance measures such as expected orbit length, expected length of the system, sojourn times and probability of server being in different states. Using MATLAB software, we have represented the graphical …

(R1984) Analysis Of M^[X1], M^[X2]/G1, G_2^(A,B)/1 Queue With Priority Services, Server Breakdown, Repair, Modified Bernoulli Vacation, Immediate Feedback, G. Ayyappan, S. Nithya, B. Somasundaram

Applications and Applied Mathematics: An International Journal (AAM)

In this investigation, the steady state analysis of two individualistic batch arrival queues with immediate feedback, modified Bernoulli vacation and server breakdown are introduced. Two different categories of customers like priority and ordinary are to be considered. This model propose nonpreemptive priority discipline. Ordinary and priority customers arrive as per Poisson processes. The server consistently afford single service for priority customers and the general bulk service for the ordinary customers and the service follows general distribution. The ordinary customers to be served only if the batch size should be greater than or equal to "a", else the server should not …

(R2024) A New Weighted Poisson Distribution For Over- And Under-Dispersion Situations, Michel Koukouatikissa Diafouka, Gelin Chedly Louzayadio, Rodnellin Onéime Malouata

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, we propose a four-parameter weighted Poisson distribution that includes and generalizes the weighted Poisson distribution proposed by Castillo and Pérez-Casany and the Conway- Maxwell-Poisson distribution, as well as other well-known distributions. It is a distribution that is a member of the exponential family and is an exponential combination formulation between the weighted Poisson distribution proposed by Castillo and Pérez-Casany and the Conway-Maxwell- Poisson distribution. This new distribution with an additional parameter of dispersion is more flexible, and the Fisher dispersion index can be greater than, equal to, or less than one. This last property allows it to …

Around The World In Two Days: Walt Disney's Epcot Center And The World's Fair Tradition, Annie Davis

Student Scholarship & Creative Works

This work views the performative and consumerist traditions of the World's Fair and how Walt Disney World's EPCOT Center was essentially created to exist as a "permanent World's Fair" in theme park form. From viewing the 1904 Louisiana Purchase Exposition in St. Louis and the 1964-1965 New York World's Fair alongside Epcot Center (1982) the similarities in the visitor experience are analyzed. Walt Disney's presence at the 1964-1965 New York World's Fair seems to work as testing grounds for ideas with lower stakes than presenting permanent attractions, some of which would later be moved to the parks. Epcot Center offered …

Greener: Graph Neural Networks For News Media Profiling, Panayot Panayotov, Utsav Shukla, Husrev T. Sencar, Mohamed Nabeel, Preslav Nakov

Natural Language Processing Faculty Publications

We study the problem of profiling news media on the Web with respect to their factuality of reporting and bias. This is an important but under-studied problem related to disinformation and “fake news” detection, but it addresses the issue at a coarser granularity compared to looking at an individual article or an individual claim. This is useful as it allows to profile entire media outlets in advance. Unlike previous work, which has focused primarily on text (e.g., on the articles published by the target website, or on the textual description in their social media profiles or in Wikipedia), here we …

Understanding And Improving The Activity Of Oxygen Evolution Reaction Catalysts In Alkaline And Chloride-Containing Electrolytes, Prajwal Adiga

Link Foundation Energy Fellowship Reports

Hydrogen is a feedstock in many chemical processes and can also be used as an energy carrier to store, move, and deliver energy produced from other sources. Recently, hydrogen is of interest for storing renewable electricity and helping address the intermittent nature of electricity generation from renewable sources.1 Water electrolysis plays a pivotal role in achieving a green hydrogen economy by sourcing electricity from intermittent renewable sources. However, the efficiency of the electrolysis process is limited by the sluggish oxygen evolution reaction (OER) kinetics,2-5 whereas the kinetics of the hydrogen evolution reaction (HER) are more facile. My work focused on …

Zero-Defect Manufacturing Utilizing Autonomation In Aerospace, Quinton L. Marks, Abeni El-Amin Ph.D.

Management Faculty Publications

Multifunctional manufacturing processes are comprised of zero-defect manufacturing (ZDM), which is inherently a complex process because of the simultaneous operations needed to accomplish zero defects. The application of the ZDM philosophy, together with autonomation, presents significant challenges and opportunities for the implementation of new processes that contribute to innovative manufacturing production processes. An emphasis must be on developing fully integrated, operative solutions, employing many quality systems, digitization, data analytics, and industry standards such as AS9100, ISO 9001, and Advanced Product Quality Planning.

(R1953) M-Regression Estimation With The K Nearest Neighbors Smoothing Under Quasi-Associated Data In Functional Statistics, Bellatrach Nadjet, Bouabsa Wahiba, Attouch Mohammed Kadi, Fetitah Omar

Applications and Applied Mathematics: An International Journal (AAM)

The main goal of this paper is to study the non parametric M-estimation under quasi-associated sequence with the k Nearest Neighbor’s method shortly (kNN). We construct an estimator of this nonparametric function and we study its asymptotic properties. Furthermore, a comparison study based on simulated data is also provided to illustrate the highly sensitive of the kNN approach to the presence of even a small proportion of outliers in the data.

Amp: Automatically Finding Model Parallel Strategies With Heterogeneity Awareness, Dacheng Li, Hongyi Wang, Eric Xing, Hao Zhang

Machine Learning Faculty Publications

Scaling up model sizes can lead to fundamentally new capabilities in many machine learning (ML) tasks. However, training big models requires strong distributed system expertise to carefully design model-parallel execution strategies that suit the model architectures and cluster setups. In this paper, we develop AMP, a framework that automatically derives such strategies. AMP identifies a valid space of model parallelism strategies and efficiently searches the space for high-performed strategies, by leveraging a cost model designed to capture the heterogeneity of the model and cluster specifications. Unlike existing methods, AMP is specifically tailored to support complex models composed of uneven layers …
