Determinants of Innovation Speed towards Innovation Performance among Factory Workers in Malaysia

The study aims to determine the relationships between the determinants of innovation speed and their impact on innovation performance among Malaysia's manufacturing industry employees. A purposive sampling technique was adopted, and 123 completed survey forms were received for further examination. The findings revealed that, except for autonomy, other determinants such as creativity, self-leadership, innovativeness, risk-taking, and proactiveness significantly impacted innovation speed. In addition, innovation speed significantly influenced the employees' innovation performance. Future research should focus on other factors that may influence the speed of innovation in different industries and how they affect different levels of the organizations.
The Impact of Physical Effort on the Gut Microbiota of Long-Distance Fliers

Flying pigeons (Columbia livia) are extensively studied for their physical endurance and superior sense of orientation. The extreme physical endurance of which these birds are capable creates a unique opportunity to investigate the possible impact of long-distance flying on the taxonomy and metabolic function of the gut microbiota. This project was enabled by access to two groups of pigeons raised by the same breeder in the same conditions, except that one group was trained in long-distance flying and participated in multiple races covering a total distance of over 2600 km over a 9-week period. In contrast, the second group did not fly. The fecal microbiota was analyzed using 16S amplicon sequencing, and the taxonomy and metabolic function were inferred from this sequence data. Based on phylogenetic distance and metabolic function, flying and non-flying pigeons were found to harbor distinct bacterial microbiota. The microbiota taxonomy varied extensively between the birds, whereas the inferred metabolic potential was relatively stable. Age was not a significant determinant of the fecal microbiota profile. In flying birds, the metabolic pathways annotated with biosynthesis were enriched, representing 60% of the 20 metabolic pathways that were most closely associated with flying.
Oriented ordering near line defects in crystals

Abstract General properties of directed ordering near line defects, in particular an edge dislocation, in elastic crystals undergoing phase transition are studied using the two-component time-dependent Ginzburg–Landau equation in two dimensions or 2D-XY model. The associated Landau potential comprises a sixth-order term, cubic anisotropy terms and the field of the dislocation. In thermodynamic equilibrium, the phase diagram for the model is delineated. Upon quenching the system below its transition point, the temporal evolution of the order parameter components in the vicinity of the defect is numerically evaluated. The development of vortices, emanated from the model, is explored and their interaction with the dislocation is examined. The dislocation produced a vortex free circular region whose diameter grew almost linearly with time. The time-dependence of vortex density for various settings of the Landau potential coefficients are evaluated. The vortex density (in 2D) decreased inversely with time, albeit faster in the absence of dislocation. By computing the two-point correlation function, we established that the dynamic scaling law is satisfied for the considered model if the distance is scaled by or by its half-width for a dislocation free crystal. Finally, phase transitions in improper ferroelectrics in the context of the model are discussed.
A Highly Efficient 165-GHz 4FSK 17-Gb/s Transceiver System With Frequency Overlapping Architecture in 65-nm CMOS

A new four-frequency-shift keying (4FSK) transceiver (TRX) at 145–185-GHz operation frequency is presented. The proposed non-coherent TRX is a fully integrated bit-in–bit-out communication system without the need for separate modulators/demodulators (modems). The transmitter (TX) core includes only one voltage-controlled oscillator (VCO), which can generate four different frequencies based on the two parallel streams of binary data at its input. The receiver (RX) with a frequency overlapping architecture demodulates the 4FSK signal and recovers the two parallel streams of binary data. Both the TX and the RX are designed and fabricated in a standard 65-nm CMOS process. The TX and RX consume 62- and 120-mW power, respectively. The highest achieved data rate is 17 Gb/s at an 18-cm link distance with 10.7-pJ/bit energy efficiency.
Hardware Design of an n-coefficient NTT-Based Polynomial Multiplier

This paper presents the design of a parameterizable n-coefficient polynomial multiplier, which performs polynomial multiplication in Zp(x)/ . This multiplier is based on an n-point radix-2 NTT-core that is designed using a systolic array. The designed NTT-based polynomial multiplier is described in generic structural VHDL; synthesized on the Stratix EP4SGX230KF40C2 using Quartus II V. 13; verified using Modelsim; and performs the product of two polynomials of degree 4095 in 95.64 µs. The hardware synthesis and performance results show that the designed polynomial multiplier presents a good area-time trade-off and it is suitable for hardware implementations of lattice-based cryptosystems.
Longitudinal Estimated Glomerular Filtration Rate Trajectories in Children with Type 1 Diabetes

Although children with type 1 diabetes (T1D) are at risk for developing diabetic kidney disease (DKD), clinical practice guidelines do not uniformly recommend routine serum creatinine (SCr) monitoring, and data describing changes in renal function from diagnosis are lacking. As part of a quality improvement initiative, the Diabetes Clinic at British Columbia Children’s Hospital in Vancouver, Canada, implemented routine serum SCr monitoring. This study describes estimated glomerular filtration rate (eGFR) trajectories and prevalence of decreased eGFR, hypertension, and albuminuria and their relationship to patterns of nephrology referral in a cohort of children aged ≤18 years (n = 307) with T1D recruited between December 2016 and February 2019. Annualized eGFR (ml/min/1.73 m2 per year) was calculated using the CKiD U25 formula and categorized as declining (<−3), stable (−3 to +3), and inclining (>+3). eGFR was categorized as normal (≥90), mildly decreased (60 to <90), and chronic kidney disease (CKD, <60). In this cohort, 54% were male; the median age at diagnosis and duration of T1D was 6.2 years and 6.9 years, respectively. Over a median follow-up of 2.3 years, declining, stable, and inclining trajectories were observed in 33%, 32%, and 35%, respectively. During their follow-up, 32% had mildly decreased eGFR, elevated blood pressures (≥90th percentile), and/or abnormal urine albumin-creatinine ratios (≥2 mg/mmol), with <10% referred for nephrology assessment. Twenty-three percent of subjects had an eGFR <90; this subgroup was more highly represented in the declining trajectory group (vs. stable and inclining). Logistic regression analysis found female sex and higher baseline eGFR to be associated with a declining eGFR trajectory. In conclusion, these data challenge the commonly held paradigm that renal function remains stable in childhood T1D and supports systematic monitoring of renal function in children with T1D, as well as collaboration across disciplines, particularly endocrinology and nephrology, to provide evidence-based individualized care.
In Situ Diagnosis of Multisite Wire Bonding Failures for Multichip IGBT Power Modules Based on Crosstalk Voltage

The online detection of aging bond wires is key to the health status awareness of smart power converters. In this article, a new health precursor of the gate voltage undershoot $V_{\mathrm {GE(pk)}}$ of the complementary switch in the half-bridge structure is proposed. It can be used to identify and distinguish multisite bonding wire failures for both insulated gate bipolar transistors (IGBTs) and freewheeling diodes (FWDs) in multichip IGBT modules. A theoretical analysis is conducted to derive this novel precursor, which is then verified by experimental results. Then, a dedicated read-out circuit is designed for the data acquisition front end that can be integrated into gate drivers for in situ monitoring. Finally, the effectiveness of this method is evaluated under changing operating conditions, including the dc-bus voltage, the load current, and the junction temperature. The effects of their fluctuations are studied and quantified, with corresponding calibration relationships provided to improve precursor accuracy.
Clinical Equivalence of Trubond® and Ethibond® Braided Polyester Sutures for Valvular Prosthesis Fixation During Aortic or Mitral Valve Replacement: A Single-Blind Randomized Controlled Trial

Background Paravalvular leak (PVL) following valve replacement is a serious cardiovascular complication that increases morbidity and mortality. Valve replacement with the interrupted suture technique using polyester suture provides adequate tensile strength and reduces the probability of tissue reaction. This study compared the clinical equivalence of Trubond®(Healthium) and Ethibond® (Ethicon, Johnson & Johnson) braided polyester sutures for valvular prosthesis fixation using interrupted suturing, with respect to the proportion of subjects having PVL after aortic valve (AV) or mitral valve (MV) replacement. Methodology Patients undergoing AV/MV replacement were enrolled and randomized in this study. The primary endpoint of this prospective, multicentric, two-arm, randomized (1:1), parallel-group, single-blind study (December 2020-October 2022) was the presence of PVL in Trubond® (n = 40) and Ethibond® (n = 42) groups within 26 weeks of surgery. The secondary endpoints included event rate of all-cause mortality, cardiac death, stroke, myocardial infarction, re-hospitalization, re-intervention, wound infection, operative time, intraoperative suture parameters, postoperative hospital stay, time to resume normal activities and work, quality of life, patient satisfaction, and adverse events in both groups. Results Patients who underwent AV/MV replacement and were followed up until 26 weeks had no incidence of PVL or other postoperative complications. No requirement for readmission or re-intervention was noted in both groups. Intraoperative suture handling characteristics, operative time, and hospital stay were also comparable between the groups. With each follow-up, subjects in both groups exhibited improved postoperative functional abilities, quality of life, and health status. Conclusions Trubond® braided polyester suture is clinically equivalent to Ethibond® braided polyester suture. Trubond® suture is safe and effective for valvular prosthesis fixation in patients undergoing AV or MV replacement.
Compact High-Voltage Pulse Discharging Switch With IGBT Stack and Simple Gate Drive Circuit

High-voltage switches composed of semiconductor switching components generally require a series stacked configuration, owing to limitations from the device voltage rating. In this configuration, isolated and synchronized gate signals should be applied to each of the switching devices for reliable operation. In this study, a high-voltage switch composed of a series stack of 12 semiconductor switches and a simple and low-cost gate drive circuit for the series stacked switch were designed. The proposed design can be applied to a low-power solid-state pulsed power modulator (SSPPM) without needing auxiliary circuits for the synchronized and isolated gate signal, by using a gate transformer with a single high-voltage cable loop on the primary side. Furthermore, the secondary side of the gate transformer has a simple circuit composed of two Zener diodes, a resistor, and a small storage capacitor. An insulated-gate bipolar transistor (IGBT) stack with 12 switches of 1200 V and 40 A rating each and a gate drive circuit were accordingly developed and proved to operate with a maximum pulse voltage and current of 10 kV and 100 A, respectively. The high-voltage switch with the IGBT-stack-based configuration was also verified to have compact dimensions of $10\times10$ cm.
Nonlinear Locomotion: Mechanics, energetics, and optimality of walking in circles and other curved paths

Most humans use walking as the primary form of locomotion for short distances. However, many scientific questions remain regarding how and why we walk the way we do. This thesis explores the energetics of “nonlinear” (or curved path) locomotion both by using computer simulations and optimization techniques as well as human subject experiments. Specifically we (1) Measure the metabolic cost of human walking around circular paths at various speeds and radii, (2) explain the trends in the metabolic cost data qualitatively using 3d trajectory optimization of a simple biped model, (3) use metabolic cost data to explain the observation that people walk slower around tighter curves and faster while walking around straight lines or bigger curves, and (4) use metabolic cost data to derive optimal locomotor paths for human walking.
An Open-Loop Adaptive Algorithm for Dynamic Multipath Estimation in DSSS Systems

In direct sequence spread spectrum systems, the multipath effect (MPE) is known to be one of the most important factors to degrade measurement accuracy. To tackle this problem, we propose a 2-D fast adaptive filtering-based multipath estimation (2D-FAFME) algorithm. A preprocessing is first introduced to compensate the waveform distortion caused by the signal path dynamic. Based on the preprocessing outputs, an optimized adaptive filter is reiteratively designed for each individual range-Doppler cell in the minimum mean-square error sense. Accurate estimates of signal path parameters can be obtained by suppressing the cross-interferences among different paths, and thus the measurement error induced by MPE can be mitigated. An improved 2D-FAFME method is further introduced to reduce the computational complexity and storage memory based on a waveform approximation. The proposed methods have lower computational burden, less storage memory, and better signal-to-noise ratio performance compared with several representative methods. The proposed methods are applicable to complex multipath scenarios, which is verified by simulation results.
Chemically coupled Hindmarsh–Rose neurons with cross interactions between membrane potential and magnetic flux

In this work, we have analysed the synchronous dynamics and pattern formation in Hindmarsh–Rose neurons with cross interactions between membrane potential and magnetic flux, in the chemical mode. The self, mixed and cross interactions are realised by varying coupling phase. The magnetic flux induces plateau bursting and amplitude death in the network. The self chemical coupling induces synchrony, whereas, the cross coupling is incapable of it. However, the cross coupling acts along with self coupling to form mixed coupling and induces synchrony in the system. The stability of the synchronous state has been studied by master stability approach. The parameter space reveals the bifurcation point at which cross coupling overrides self coupling effects. The synchronising ability of interactions are justified in a network of neurons as well. The statistical factor of synchronisation quantifies the amount of synchrony in the network in different interaction modes. The combined effect of non local interactions and mixed coupling of variables initiates the emergence of chimera and multichimera states. However, in cross-coupled systems, only incoherent states are present. The existence of chimera and multichimera states are confirmed by calculating the strength of incoherence and discontinuity measure. The analysis of spatiotemporal patterns reveals the presence of travelling chimeras within the network. The Hamilton energy function indicate that a greater amount of energy is required to sustain coherent neurons at higher potential. This work may enhance the understanding of chimera states and improve its applicability to real-world systems.
Fusion for Multiple Light Sources in Texture Mapping Object

Abstract—In this paper, fusion method using wavelet transform was used to calculate the effects of multiple sources of light to make the object look more realistic and more informative than the original parts which take the effect of each light source alone. The color value of any pixel in the object depends essentially on the color of the specific mapped texture as well as on the effect of the light sources that produce bright or dark pixels value depending on the distance between the pixel and light source and the direction of light rays. The proposed method merges the effect of multiple lights. Instead of summing these effects, the method takes from each pixel one of three conditions. These states are the maximum effect among all sources of the light, the minimum effect among all sources to reflect fine shadow and the ratio effect from all sources. This ratio depends on the relative parameters among all sources.
A Review of Longitudinal Analysis: Modeling Within-Person Fluctuation and Change

Longitudinal statistical models are now frequently used in social, behavioral, and health science research to investigate how individuals or groups of individuals’ performances, achievement, attitudes, and interests change over time. They are also used to determine whether growth is greater for one subpopulation than for another or to ascertain whether the change process can be predicted from time-invariant or time-variant covariates. Given the desirable features that longitudinal data can bring and the widespread uses of longitudinal statistical models, a graduate-level full semester course on statistical analysis of longitudinal data is now offered in a majority of institutions by faculty from psychology (e.g., quantitative or developmental psychologists), educational psychology, human development, business, or other social science departments. When I was first asked by the editor to review the book by Dr. Lisa Hoffman entitled Longitudinal Analysis: Modeling Within-Person Fluctuation and Change, I was a bit hesitant because longitudinal analysis was not my original area of expertise. In fact, the graduate school I attended did not offer a separate course on longitudinal statistical models at that time (2007–2012), and this topic was taught as part of the general course on hierarchical linear modeling (HLM). The textbook used for HLM was Snijders and Bosker’s (1999) Multilevel Analysis: An Introduction to Basic and Advanced Multilevel Modeling, in which Chapter 12 was specifically devoted to longitudinal data. Now with a strong desire to learn in-depth knowledge of longitudinal modeling, I finished reading Hoffman’s book, and I was just amazed. The book provides a comprehensive account of knowledge on both introductory and advanced linear models for longitudinal data analysis. The materials are presented in an accessible and conversational style, and hence they are nonthreatening to nonmathematically oriented readers. On the other hand, the book also contains the latest, most advanced models and applications (Section IV) with enough technical rigors to inspire quantitative researchers, like myself, to work on further generalizations.

Uloga obiteljske socijalizacije i samopoštovanja u odnosu korištenja internetskih društvenih mreža i zadovoljstva tjelesnim izgledom kod adolescentica

Istraživanja konzistentno upucuju na povezanost izloženosti medijskim sadržajima i nezadovoljstva vlastitim tjelesnim izgledom, osobito među mlađom ženskom populacijom, uz sto se vežu dalekosežne psihosocijalne posljedice. Prema sociokulturnom modelu i teoriji objektivizacije, drustveno uvjetovane norme poželjnog tjelesnog izgleda podržavaju objektivizirajuci pogled na vlastito tijelo, a reproduciraju se i internaliziraju upotrebom medija. Recentnija poimanja medijskih utjecaja prosiruju se na internetske drustvene mreže, koje postaju sve važniji izvor medijskih sadržaja, ali i komunikacijsko sredstvo samopromocije te primanja povratnih informacija o vlastitom izgledu i aktivnostima. U nastojanju da se primjena sociokulturnog modela prosiri na internetske drustvene mreže te detektira moguce protektivne faktore, u ovom su istraživanju testirani dosad tek djelomicno provjeravani modeli odnosa među nekima od temeljnih dimenzija razvoja (ne)zadovoljstva vlastitim tjelesnim izgledom (internalizacija ideala tjelesnog izgleda, samonadzor, obiteljska socijalizacija, samopostovanje i utjecaj drustvenih mreža). Podaci su prikupljeni internetskim anketnim istraživanjem na uzorku od 1.301 ucenice drugih razreda srednjih skola u Zagrebu i Zagrebackoj županiji. Rezultati podupiru postavke sociokulturnog modela u kontekstu koristenja internetskih drustvenih mreža. Upotreba drustvenih mreža pokazala se povezanom s nezadovoljstvom tjelesnim izgledom posredstvom internalizacije ideala tjelesnog izgleda. Pokazalo se i da je odnos internalizacije i zadovoljstva tjelesnim izgledom djelomicno posredovan samonadzorom, sto je u skladu s pretpostavkama teorije objektivizacije. Nije potvrđen moderatorski utjecaj samopostovanja na odnos između internalizacije ideala izgleda i zadovoljstva vlastitim izgledom, ali se samopostovanje pokazalo izravnim prediktorom zadovoljstva izgledom. Utvrđeno je i da neki aspekti obiteljske socijalizacije djeluju na samopostovanje, sto upucuje na moguci mehanizam protektivnog ucinka tog oblika socijalizacije te mogucnost prevencije stetnih ishoda medijske idealizacije tjelesnog izgleda i naglasavanja njegove važnosti djelovanjem na izgradnju samopostovanja adolescentica. Preventivno djelovanje usmjereno na izgradnju samopostovanja mladih ljudi ostvarivo je i kroz obrazovni sustav.
An Investigation of the Nonlinear and Asymmetric Spillover Effects of U.S. Economic Policy Uncertainty on Bond Return Volatility of Emerging Markets

ABSTRACT This paper investigates the nonlinear and asymmetric relationships between the U.S. economic policy uncertainty (EPU) index and the volatility of bond returns in 36 emerging markets (EMs) using panel quantile regression methods. Our findings indicate that the spillover effects of the U.S. EPU on the volatility of bond returns are strong in EMs, particularly in the upper quantiles of volatility, and are substantial in magnitude. We also explore the impact of the U.S. monetary policy uncertainty (MPU) index and fiscal policy uncertainty (FPU) indices on the volatility of bond returns in 36 EMs, and observe a positive correlation between both the U.S. MPU and the U.S. FPU and bond return volatility in EMs. Of all the spillover effects, the U.S. MPU has the largest magnitude. Additionally, our results demonstrate that the spillover effects induced by three U.S. policy uncertainties are sensitive to the macroeconomic environment, with a stronger impact during financial crises and in countries with high degrees of financial openness.
