Factors Affecting Customer Satisfaction in Fast Food Restaurant “Jollibee” during the COVID-19 Pandemic

Jollibee is one of the most widely known fast food in Filipino-based restaurants in the world. However, the COVID-19 pandemic has impacted restaurants across the world. The decrease in profit and dividend, and even closure of branches were evident. This study aimed to determine the relationships between Jollibee’s price, food quality, culture/social influence, and service quality through the SERVQUAL dimensions on customer satisfaction during the COVID-19 pandemic using the structural equation modeling (SEM) approach. A total of 303 respondents were recruited using a purposive sampling approach to answer an online survey through social media platforms. This study found that among the factors mentioned, responsiveness, reliability, and assurance dimensions yielded to be statistically insignificant to the service quality. Due to the normal attributes the staff and restaurant have, the different factors were deemed insignificant. At the same time, the service quality was observed to have the largest significant direct relationship with customer satisfaction, followed by the cultural influence, food quality, COVID-19 protocols, and pricing. It was also seen that cleanliness and appearance, empathetic staff, food quality, price, and proper implementation of COVID-19 protocol prevention would lead to high levels of satisfaction among customers in Jollibee fast-food restaurant. Moreover, cultural/social influence has played a big role seeing that the indicators represent the feeling of belongingness since childhood. This study is the first study that analyzed the factors affecting the customer satisfaction of Jollibee. Finally, this study could be used as a basis for fast-food companies and service-related industries to increase its performance by enhancing customer satisfaction worldwide.
Optical rectification and shift currents in GaAs and GaP response: Below and above the band gap

We present a full band structure scheme to calculate the electronic contribution to the second order susceptibility coefficient pertinent to optical rectification, ${\ensuremath{\chi}}_{2}^{abc}(\ensuremath{-}{\ensuremath{\omega}}_{\ensuremath{\sum}};{\ensuremath{\omega}}_{\ensuremath{\beta}},{\ensuremath{\omega}}_{\ensuremath{\gamma}})$ where ${\ensuremath{\omega}}_{\ensuremath{\sum}}\ensuremath{\approx}0$, within the independent particle approximation for the electron dynamics, and in the dipole limit. This allows us to determine the electronic response of a bulk semiconductor to a femtosecond optical pulse over a range of central frequencies, both below and above the band gap frequency. Particularly interesting is the limit ${\ensuremath{\chi}}_{2}^{abc}(0;\ensuremath{\omega},\ensuremath{-}\ensuremath{\omega})$. In addition to the usual near-dc interband rectification current, shift and injection currents, associated with actual divergences in ${\ensuremath{\chi}}_{2}^{abc}(0;\ensuremath{\omega},\ensuremath{-}\ensuremath{\omega})$, are taken into account. Calculations for GaAs and GaP, in which injection currents are forbidden, are performed. The band energies and matrix elements are computed with the full potential linearized augmented plane wave method. For frequencies above the band gap, and for typically available pulse widths, we demonstrate that the shift current dominates the current response, being approximately two orders of magnitude larger than the rectification current. For very narrow pulse widths, on the order of a femtosecond, the rectification current becomes comparable to the shift current.
On diagonal quasi-free automorphisms of simple Cuntz-Krieger algebras

We show that an outer action of a finite abelian group on a simple Cuntz-Krieger algebra is strongly approximately inner in the sense of Izumi if the action is given by diagonal quasi-free automorphisms and the associated matrix is aperiodic. This is achieved by an approximate cohomology vanishing-type argument for the canonical shift restricted to the relative commutant of the set of domain projections of the canonical generating isometries in the fixed point algebra.
EUS-guided cyanoacrylate injection into the perforating vein versus direct endoscopic injection in the treatment of gastric varices

Abstract Background and study aims Endoscopic injection of gastric varices (GVs) using cyanoacrylate (CYA) is associated with significant adverse events (AEs). We aimed to compare the efficacy and safety of endoscopic ultrasound (EUS)-guided CYA injection into the perforating vein versus direct endoscopic injection (DEI) of CYA in treatment of high-risk GVs. Patients and methods This was a randomized controlled trial that included 52 patients with high-risk GVs. Group A underwent EUS-guided injection into the perforator vein and Group B underwent DEI of 1 mL CYA. Endoscopic examination and Doppler EUS were repeated after 3 months to confirm eradication. Obliteration by Doppler EUS was considered by absence of Doppler flow within the varix. Repeated injection was performed in the absence of obliteration. Doppler EUS examination was repeated at 3 and 6 months after each injection. Results Forty-three patients including 27 males and 16 females with mean age 57 years completed the study. Variceal obliteration was achieved during the index session after 3 months in eight of 21 (38.1 %) in group B compared to 17 of 22 (77.2 %) in group A ( P = 0.014). There was a significant difference in the amount of CYA needed to achieve obliteration in group B compared to group A (2 vs.1 mL, P = 0.027). There was no statistically significant difference in the overall AE rate between group A and group B (4.5 % vs. 14.3 %, P = 0.345). Conclusions EUS-guided CYA injection into the perforating veins achieved less amount of CYA, fewer number of sessions to obliteration, and similar overall AE rates in the treatment of high-risk GVs compared to DEI.
A new way to evaluate MOY graphs

We define a new way to evaluate MOY graphs. We prove that this new evaluation coincides with the classical evaluation by checking some skein relations. As a consequence, we prove a formula which relates the $\mathfrak{sl}_N$ and $\mathfrak{sl}_{N-1}$-evaluations of MOY graphs.
A Development of New Material for 4D Printing and the Material Properties Comparison between the Conventional and Stereolithography Polymerised NVCL Hydrogels

The term 4D printing refers to the idea that the shape or properties of a printed object can be changed when an external stimulus is applied. In this contribution, a temperature-responsive polymer Poly (N-vinyl caprolactam) (PNVCL), which is normally prepared via radical free polymerization, was used to justify the 4D printing concept. As a result, by using a Stereolithography (SLA) 3D printer, 4D prints were successfully prepared. These prints were able to demonstrate intelligent and reversible expansion/shrinkage behaviour as the temperature increases and decreases. Additionally, in order to examine the differences in chemical structure, thermal properties, mechanical properties, and swelling behaviours of the photopolymerised and printed parts, a series of characterisation tests, including Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), goniometry, tensile test, gel fraction measurement and pulsatile swelling study were performed on this study. In conclusion, the differences between polymerisation methods are significant; despite their chemical structures and thermal properties being similar, there were significant differences with regard to tensile properties, swellability and wettability of samples. The implications of conducting this study are remarkable, not only in providing a new way of preparing NVCL, but also in demonstrating the possibility of using 4D printed NVCL for practical applications.
Additive Volume of Sets Contained in Few Arithmetic Progressions

A conjecture of Freiman gives an exact formula for the largest volume of a finite set $A$ of integers with given cardinality $k = |A|$ and doubling $T = |2A|$. The formula is known to hold when $T \le 3k-4$, for some small range over $3k-4$ and for families of structured sets called chains. In this paper we extend the formula to sets of every dimension and prove it for sets composed of three segments, giving structural results for the extremal case. A weaker extension to sets composed of a bounded number of segments is also discussed.
Rapid, Sensitive and Simultaneous Detection of Two Wheat RNA Viruses Using Reverse Transcription Recombinase Polymerase Amplification (RT-RPA)

In China, wheat yellow mosaic disease is mostly caused by wheat yellow mosaic virus (WYMV) and Chinese wheat mosaic virus (CWMV). If wheat is co-infected with these two viruses, it can cause severe yellow mosaic symptoms and yield losses. Early detection of viruses is crucial for preventing disease in the field. In this study, we optimized a sensitive, specific reverse transcription recombinase polymerase amplification (RT-RPA) detection method for two viruses, WYMV and CWMV. Two sets of primers were designed based on the capsid protein (CP)-encoding genes of the two viruses, and the reaction conditions were determined. The RT-RPA method, which amplified the target amplicon by a handheld reaction mixture for 20 min, was more sensitive than PCR-CP in the detection of WYMV. Finally, the RT-RPA method was performed on 110 randomly selected field samples, demonstrating its applicability to samples from different regions and specificity for co-infected samples. This study not only describes an improved method for detecting WYMV and CWMV using RT-RPA but also demonstrates the potential of this method, which could be applied under field conditions.
Effects of Initial Stresses and Wall Thickness on Wave Characteristics in Elastic Tubes

Employing the theory of small deformations superimposed on large initial static deformations, the propagations of harmonic waves in an initially stressed thick elastic tube filled with a viscous fluid is studied. Due to variability of the coefficients of the resulting differential equation of the tube, the field equations are solved by a power series method. Utilizing the properly posed boundary conditions that characterize the reaction of fluid with the tube wall, the dispersion relation is obtained as a function of initial deformations and the geometrical characteristics. The dispersion equation is examined analytically, whenever it is possible, and numerically, and the results are depicted on some graphs. It is observed that wave speeds increase with thickness parameter. Unter der Verwendung der Theorie der kleinen Deformationen, die grosen statischen Deformationen am Eingang uberlagert werden, wird die Ausbreitung harmonischer Wellen in einer vorgespannten dicken elastischen Rohre, die mit einem viskosen Fluid gefullt ist, untersucht. Aufgrund der Veranderlichkeit der Koeffizienten der resultierenden Differentialgleichung der Rohre werden die Feldgleichungen mit einer Potenzreihenmethode gelost. Unter Verwendung der richtig gestellten Grenzbedingungen, die die Reaktion des Fluids mit der Rohrenwand charakterisieren, wird die Dispersionsbeziehung als Funktion der Anfangsdeformationen und der geometrischen Kennzeichen erhalten. Die Dispersionsbeziehung wird numerisch und —- wenn moglich —- analytisch gepruft, und die Resultate werden graphisch dargestellt. Es zeigt sich, das die Wellengeschwindigkeiten mit den Dickenparameter wachsen.
Extra force in f(R) modified theories of gravity

The equation of motion for massive particles in f(R) modified theories of gravity is derived. By considering an explicit coupling between an arbitrary function of the scalar curvature, R, and the Lagrangian density of matter, it is shown that an extra force arises. This extra force is orthogonal to the four-velocity and the corresponding acceleration law is obtained in the weak-field limit. Connections with MOND and with the Pioneer anomaly are further discussed.
Clinicopathological Features of Breast Cancer in Relation to Exposure of Cycling Reproductive Hormones: A Multicenter Retrospective Study of 14 731 Patients Diagnosed with Invasive Breast Cancer

Background The reproductive period for women begins at menarche and ends at menopause, representing the total time period of exposure to cycling reproductive hormones. The potential associations between clinicopathological features and exposure of cycling reproductive hormones has not been extensively studied. This retrospective study enrolled 14 731 patients diagnosed with invasive breast cancer and was designed to evaluate factors associated with the reproductive period on breast cancer type and patient outcomes. Material/Methods A total of 14 731 female breast cancer patients from the Western China Clinical Cooperation Group from January 1, 2008, to December 31, 2017, were enrolled. Unconditional logistic regression was performed to assess the associations between clinicopathological features and menarche age, menopause age, and reproductive years. The differences in risk factors between lower and higher number of reproductive years (<35 and ≥35 years) were examined with the chi-square test. Results First, patients with late menarche age were more likely to present with tumors of higher histological grade and larger size. Second, the findings suggested a higher likelihood of smaller tumor size in postmenopausal patients with a greater length of reproductive years. Conversely, higher histological grade was associated with this group of patients, compared with their counterparts with shorter reproductive years. Third, patients with luminal breast cancer with a greater length of reproductive years were more likely to present larger tumors. Conclusions Our findings indicated that several clinicopathologic factors, including tumor size and histological grade, were associated with the length of reproductive years in patients diagnosed with breast cancer.
The algebra of the Catalan monoid as an incidence algebra: A simple proof

We give a direct straightforward proof that there is an isomorphism between the algebra of the Catalan monoid C_n that is, the monoid of all order-preserving, weakly increasing self-maps f of [n] = {1,. ,n}, over any commutative ring with identity and the incidence algebra of a certain poset over the ring.
Large-amplitude topographic waves in 2D stratified flow

Our fundamental understanding of steady, stratified flow over two-dimensional (2D) topography rests on the pioneering works of G. Lyra and R. Long. Within linear theory, Lyra established the far-field radiation conditions that determine the downstream pattern of buoyancy waves. Soon after, Long discovered that the steady, nonlinear streamfunction for special cases of stratified, 2D flow could satisfy the same equations as linear theory, subject to an exact topographic boundary condition. Fourier methods are currently used to compute solutions to Long's theory for arbitrary topography in the near-hydrostatic or small-amplitude topographic parameter regimes. It is not generally appreciated however, that these methods encounter difficulties for flows that are both strongly non-hydrostatic and beyond linear amplitudes. By recasting Long's theory into a linear integral equation, this difficulty is shown to be a computational barrier associated with an ill-conditioning of the Fourier method. The problem is overcome through the development of a boundary integral computation which relies on some lesser known solutions from Lyra's original analysis. This method is well-conditioned for strongly non-hydrostatic flows, and is used to extend the exploration of critical overturning flows over Gaussian and bell-shaped ridges. These results indicate that the critical value of the non-dimensional height () asymptotes to a finite value with increasing non-hydrostatic parameter ().
Towards the Digital Twin (DT) of Narrow-Band Internet of Things (NBIoT) Wireless Communication in Industrial Indoor Environment

A study of the behavior of NB-IoT wireless communication in an industrial indoor environment was conducted in this paper. With Wireless Insite software, a scenario in the industrial sector was simulated and modeled. Our research examined how this scenario or environment affected the communication parameters of NB-IoT’s physical layer. In this context, throughput levels among terminals as well as between terminals and transceiver towers, the power received at signal destination points, signal-to-noise ratios (SNRs) in the environment, and distances between terminals and transceivers are considered. These simulated results are also compared with the calculated or theoretical values of these parameters. The results show the effect of the industrial setting on wireless communication. The differences between the theoretical and simulated values are also established.
Basic principles of hp virtual elements on quasiuniform meshes

In the present paper we initiate the study of hp Virtual Elements. We focus on the case with uniform polynomial degree across the mesh and derive theoretical convergence estimates that are explicit both in the mesh size h and in the polynomial degree p in the case of finite Sobolev regularity. Exponential convergence is proved in the case of analytic solutions. The theoretical convergence results are validated in numerical experiments. Finally, an initial study on the possible choice of local basis functions is included.
Étale Homotopy Obstructions of Arithmetic Spheres

Let $K$ be a field of characteristic $\ne 2$ and let $X$ be the affine variety over $K$ defined by the equation $$ X:\ a_0x_0^2 + \cdots + a_nx_n^2 = 1 $$ where $n\ge 0$ and $a_i\in K$. In this paper we compute the lowest mod 2 etale homological obstruction class to the existence of a $K$-rational point on $X$, and show that it is the cup product of the form $$ o_{n+1} = [a_0]\cup\cdots\cup[a_n]. $$ Our computation is an etale-homotopy analogue of the topological fact that Stiefel-Whitney classes are the homological obstructions to find a section to the unit sphere bundle of a real vector bundle.
Matrix transformations on the matrix domains of triangles in the spaces of strongly $C_1$-summable and bounded sequences

Let , and be the sets of sequences that are strongly summable to zero, summable and bounded of index p ≥ 1 by the Cesàro method of order 1, which were introduced by Maddox [I. J. Maddox, On Kuttner’s theorem, J. London Math. Soc. 43 (1968), 285–290]. We study the matrix domains = (w 0)T , = (w )T and = (w ∞)T of arbitrary triangles T in , and , determine their β-duals, and characterize matrix transformations on them into the spaces c0, c and `∞.
Semiinfinite cohomology of associative algebras and bar duality

We describe semiinfinite cohomology of associative algebras in terms of Koszul (or bar) duality. Consider an associative algebra $A$ and two its subalgebras $B$ and $N$ such that $A=B\otimes N$ as a vector space. We prove that the endomorphism algebra of the semiregular $A$-module appears naturally in semiinfinite cohomology theory as a ``two times Koszul dual'' to the algebra $A$. We compare semiinfinite cohomology of universal enveloping algebras with the well-known Lie algebra semiinfinite cohomology. A new description of the critical 2-cocycle is provided. As a consequence we obtain another proof of the fact that additive categories generated by Verma modules over affine Lie algebras on dual levels are antiequivalent.
Limiting behaviour of the Ricci flow

We will consider a {\it $\tau$-flow}, given by the equation $\frac{d}{dt}g_{ij} = -2R_{ij} + \frac{1}{\tau}g_{ij}$ on a closed manifold $M$, for all times $t\in [0,\infty)$. We will prove that if the curvature operator and the diameter of $(M,g(t))$ are uniformly bounded along the flow, then we have a sequential convergence of the flow toward the solitons.
Fermionic and bosonic Laughlin state on thick cylinders

We investigate a many-body wave function for particles on a cylinder known as Laughlin's function. It is the power of a Vandermonde determinant times a Gaussian. Our main result is: in a many-particle limit, at fixed radius, all correlation functions have a unique limit, and the limit state has a non-trivial period in the axial direction. The result holds regardless how large the radius is, for fermions as well as bosons. In addition, we explain how the algebraic structure used in proofs relates to the formalism of quasi-state decompositions.
Atmospheric Temperature Prediction Based on a BiLSTM-Attention Model

To address the problem that traditional models are not effective in predicting atmospheric temperature, this paper proposes an atmospheric temperature prediction model based on symmetric BiLSTM (bidirectional long short-term memory)-Attention model. Firstly, the meteorological data from five major stations in Beijing were integrated, cleaned, and normalized to build an atmospheric temperature prediction dataset containing multiple feature dimensions; then, a BiLSTM memory network was used to construct with forward and backward information in the time dimension. And the limitations of the traditional LSTM method in long-term time series analysis were solved by introducing the attention mechanism to achieve the prediction analysis of atmospheric temperature. Finally, by comparing the prediction results with those of BiLSTM, LSTM-Attention, and LSTM, it is revealed that the proposed model has the best prediction effect, with a MAE value of 0.013, which is 0.72%, 0.41%, and 1.24% lower than those of BiLSTM, LSTM-Attention, and LSTM, respectively; the R2 value reaches 0.9618, which is 2.73%, 1.23%, and 4.98% higher than BiLSTM, LSTM-Attention, and LSTM, respectively. The results show that the symmetrical BiLSTM-Attention atmospheric temperature prediction model can effectively improve the prediction accuracy of temperature data, and the model can also be used to predict other time series data.
