Teknologi RFID dalam bidang keamanan menarik untuk dikembangkan. Salah satunya adalah aplikasi pada sistem monitoring pengunjung perpustakaan. Penerapan sistem monitoring pada perpustakaan dapat mengetahui seberapa besar minat baca dari jumlah pengunjung yang datang. Karena itu penerapan sistem monitoring sangat diperlukan di perpustakaan UNWAHA. Didalam perpustakaan UNWAHA sudah ada sistem monitoring namun masih menggunakan sistem manual dengan mengisi data kunjungan kedalam buku kehadiran. Pada sistem manual ini belum ada pengontrol keluar masuknya pengunjung, hal ini membuat pengunjung dapat masuk dan keluar secara bebas walaupun tanpa mengisi buku absensi. Selain itu manipulasi data identitas pengunjung pada sistem manual sangat mudah dilakukan. Maka dari itu dibuatlah sistem monitoring pengunjung perpustakaan menggunakan RFID berbasis WEB. Pada sistem ini dapat menangani data kunjungan secara real time dengan melakukan taping kartu E-KTP oleh pengunjung. Sistem monitoring ini menggunakan NodeMCU yang terhubung ke database MySql dan dilengkapi pengunci pintu otomatis yang dapat membuka apabila menempelkan kartu E-KTP yang sudah terdaftar pada RFID. Selain itu dengan adanya sistem monitoring ini dapat mengontrol keluar masuknya pengunjung dan dapat meminimalisir manipulasi data kunjungan.

Motorcycles are a popular transportation in Indonesia, besides because the price is quite affordable time efficiency is also a benchmark for why Indonesians prefer motorcycles than any other means of transportation. To lighten the burden of purchasing a motorcycle, it is necessary to make purchases on credit. However, bad credit is not uncommon for some of the problems that arise. Therefore, in this study will be applied to a decision support system using Simple Additive weighting method (SAW) to assess the credit application. SAW method is the simplest method of MADM because the basic concept SAW method is to find the sum of the weighted performance rating for each alternative on all attributes. Values obtained criteria of each customer or alternatively along the desired selection of motorcycles will be entered into the decision support system and will be calculated. Then the system will display the results of these calculations and shows the feasibility of the credit application. In this decision support system using five criteria, personality of the installment payment of financial institutions, income, business or employment status, home status and dependents.

Diameter Dependent Melting and Softening of dsDNA Under Cylindrical Confinement

Published: May 2022

Carbon nanotubes (CNTs) are considered promising candidates for biomolecular confinement, including DNA encapsulation for gene delivery. Threshold values of diameters have been reported for double-stranded DNA (dsDNA) encapsulation inside CNTs. We have performed all-atom molecular dynamics (MD) simulations of dsDNAs confined inside single-walled CNTs (SWCNTs) at the physiologically relevant temperature of 300 K. We found that the dsDNA can be confined without being denatured only when the diameter of the SWCNT exceeds a threshold value. Below this threshold diameter, the dsDNA gets denatured and melts even at the temperature of 300 K. Our simulations using SWCNTs with chirality indices (20,20) to (30,30) at 300 K found the critical diameter to be 3.25 nm (corresponding to (24,24) chirality). Analyses of the hydrogen bonds (H-bonds), Van der Walls (VdW) energy, and other inter-base interactions show drastic reduction in the number of H-bonds, VdW energy, and electrostatic energies between the bases of dsDNA when it is confined in narrower SWCNTs (up to diameter of 3.12 nm). On the other hand, the higher interaction energy between the dsDNA and the SWCNT surface in narrower SWCNTs assists in the melting of the dsDNA. Electrostatic mapping and hydration status analyses show that the dsDNA is not adequately hydrated and the counter ion distribution is not uniform below the critical diameter of the SWCNT. As properly hydrated counter ions provide stability to the dsDNA, we infer that the inappropriate hydration of counter ions and their non-uniform distribution around the dsDNA cause the melting of the dsDNA inside SWCNTs of diameter below the critical value of 3.25 nm. For confined dsDNAs that do not get denatured, we computed their elastic properties. The persistence length of dsDNA was found to increase by a factor of about two and the torsional stiffness by a factor of 1.5 for confinement inside SWCNTs of diameters up to 3.79 nm, the stretch modulus also following nearly the same trend. Interestingly, for higher diameters of SWCNT, 3.79 nm and above, the dsDNA becomes more flexible, demonstrating that the mechanical properties of the dsDNA under cylindrical confinement depend non-monotonically on the confinement diameter.

BackgroundRed blood cell distribution width (RDW) is associated with cardiovascular mortality. However, the relationship between preoperative RDW and outcomes after thoracic endovascular aortic repair (TEVAR) in type B aortic dissection (TBAD) remains to be determined.MethodsWe review the records of 678 patients with TBAD and treated with TEVAR in three centers. Patients were divided into two groups according to the admission RDW cut-off by receiver operating characteristic curve analysis [≤13.5% (n = 278) and &gt;13.5% (n = 400)]. The association between RDW and long-term mortality was evaluated using Cox survival analysis. Additionally, we used general additive models (GAM) with restricted cubic splines (RCS) to explore non-linear relationships between RDW and outcomes.ResultsSubjects with a high RDW had significantly higher in-hospital mortality rates (1.4 vs. 4.3%, P = 0.038). A total of 70 subjects died after a median follow-up period of 3.3 years. Kaplan–Meier analysis showed that subjects with an RDW &gt;13.5% had worse survival rates than those with lower RDW values (P &lt; 0.001). Multivariate Cox proportional hazard modeling revealed that an RDW &gt;13.5% was an independent predictor of long-term mortality (adjusted HR = 2.27, P = 0.006). Also, we found that there was a non-linear relationship between RDW and mortality from RCS, and RDW of 13.5% might be an inflection point to distinguish the long-term mortality risk of TBAD patients.ConclusionAs an inexpensive and routinely measured parameter, RDW holds promise as a novel prognostic marker in patients with TBAD receiving TEVAR. We found that an RDW &gt;13.5% on admission was independently associated with increased long-term mortality.

BackgroundPercutaneous coronary intervention (PCI) of Chronic total occlusions (CTOs) has been traditionally considered a challenging procedure, with a lower success rate and a higher incidence of complications compared to non-CTO-PCI. An accurate and comprehensive evaluation of potential candidates for CTO-PCI is of great importance. Indeed, assessment of myocardial viability, left ventricular function, individual risk profile and coronary lesion complexity as well as detection of inducible ischemia are key information that should be integrated for a shared treatment decision and interventional strategy planning. In this regard, multimodality imaging can provide combined data that can be very useful for the decision-making algorithm and for planning percutaneous CTO recanalization.AimsThe purpose of this article is to appraise the value and limitations of several non-invasive imaging tools to provide relevant information about the anatomical characteristics and functional impact of CTOs that may be useful for the pre-procedural assessment and follow-up of candidates for CTO-PCI. They include echocardiography, coronary computed tomography angiography (CCTA), nuclear imaging, and cardiac magnetic resonance (CMR). As an example, CCTA can accurately delineate CTO location and length, distal coronary bed, vessel tortuosity and calcifications that can predict PCI success, whereas stress CMR, nuclear imaging and stress-CT can provide functional evaluation in terms of myocardial ischemia and viability and perfusion defect extension.

BackgroundStroke is predominately attributed to left atrial thrombus (LAT) in patients with non-valvular atrial fibrillation (NVAF), however, its detection rate in real clinical practice has been few reported in China.ObjectiveThis study aimed to investigate the prevalence and associated factors of LAT in patients with NVAF in China.MethodsAll adult NVAF patients undergoing transesophageal echocardiography (TEE) in the China Atrial Fibrillation Center database from January 2017 to January 2022 were enrolled in this study. The prevalence of LAT was calculated, and associated factors were identified.ResultsA total of 36,007 NVAF inpatients from 602 hospitals in 30 provinces/autonomous regions/municipalities were included in the final analysis, with a median age of 66 years and 39.4% were female. LAT was present in 1,467 (4.1%) patients overall, 2.7, 5.7, and 6.8% in patients with paroxysmal, persistent, and long-standing persistent AF, respectively. In subgroup analysis, including age ≥ 65 years, CHA2DS2-VASC score ≥ 2, left atrial diameter (LAD) ≥ 50 mm, left ventricular ejection fraction (LVEF) &lt; 50%, and anticoagulation, patients with paroxysmal AF always had the lowest LAT prevalence, followed by patients with persistent and long-standing persistent AF. Patients treated with anticoagulants had less prevalent LAT than those without anticoagulation (2.1 vs. 5.0%, p &lt; 0.001). In multivariate analysis, AF pattern (both persistent AF and long-standing persistent AF), hypertension, chronic heart failure, coronary heart disease, transient ischemic attack/stroke, diabetes mellitus, and LAD (per 5 mm) were associated with an increased prevalence of LAT. However, LVEF (per 5%) and anticoagulation were associated with a reduced prevalence of LAT.ConclusionLAT was found in 4.1% of Chinese adult NVAF inpatients underwent TEE in real-world experience. The prevalence of LAT mainly associated with non-paroxysmal AF, cardiovascular diseases, diabetes mellitus, enlarged left atrium, lower LVEF, and lack of anticoagulation therapy.

BackgroundWhether left ventricular non-compaction (LVNC) bears a different prognosis than dilated cardiomyopathy (DCM) is still a matter of debate.MethodsFrom a multicenter French prospective registry, we compared the outcomes of 98 patients with LVNC and 65 with DCM. The primary endpoint combined cardiovascular death, heart transplantation, and hospitalization for cardiovascular events. The two groups presented similar outcomes but different left ventricular ejection fractions (LVEF) (43.3% in LVNC vs. 35.95% in DCM, p = 0.001). For this reason, a subgroup analysis was performed comparing only patients with LVEF ≤ 45%, including 56 with LVNC and 49 with DCM.ResultsAmong patients with LVEF≤ 45%, at 5-year follow-up, the primary endpoint occurred in 33 (58.9%) among 56 patients with LVNC and 18 (36.7%) among 49 patients with DCM (p = 0.02). Hospitalization for heart failure (18 [32.14%] vs. 5 [10.20%], p = 0.035) and heart transplantation were more frequent in the LVNC than in the DCM group. The incidences of rhythmic complications (24 [42.85%] vs. 12 [24.48%], p = 0.17), embolic events, and cardiovascular death were similar between LVNC and DCM cases. Among the 42 patients with LVNC and LVEF &gt; 45%, the primary endpoints occurred in only 4 (9.52%) patients, including 2 hospitalizations for heart failure and 3 rhythmic complications, but no embolic events.ConclusionIn this prospective cohort, patients with LVNC who have left ventricular dysfunction present a poorer prognosis than DCM patients. Heart failure events were especially more frequent, but embolic events were not. Patients with LVNC and preserved ejection fraction present very few events in 5 years.

IntroductionAlbuminuria is a well-known risk factor for end-stage kidney disease, all-cause mortality, and cardiovascular mortality, even when the albumin-to-creatinine ratio is &lt;30 mg/g. However, the association between transiently observed trace albuminuria and these major adverse outcomes has not yet been reported. This study aimed to examine the effect of transient albuminuria on these major adverse outcomes using the National Health Insurance Service data in Korea.Methods and ResultsThe National Health Insurance Service-National Sample Cohort from Korea, followed from 2002 to 2015, consisted of 1,025,340 individuals, accounting for 2.2% of the total Korean population. We analyzed the effect of transient albuminuria on all-cause death, cardiovascular death, and incident chronic kidney disease (CKD) and compared it with the group without albuminuria. Among 1,025,340 individuals, 121,876 and 2,815 had transient albuminuria and no albuminuria, respectively. Adjusted hazard ratios of the transient albuminuria group for cardiovascular death and incident CKD were 1.76 (1.01–3.08) and 1.28 (1.15–1.43), respectively. There were significant differences in all-cause death, cardiovascular death, and incident CKD between the two groups after propensity score matching (p = 0.0037, p = 0.015, and p &lt; 0.0001, respectively). Propensity score matching with bootstrapping showed that the hazard ratios of the transient albuminuria group for all-cause death and cardiovascular death were 1.39 (1.01–1.92) and 2.18 (1.08–5.98), respectively.ConclusionsIn this nationwide, large-scale, retrospective cohort study, transient albuminuria was associated with all-cause death, cardiovascular death, and incident CKD, suggesting that transient albuminuria could be a risk marker for adverse outcomes in the future, and that its own subclinical phenotype could play an important role during the course of CKD.

BackgroundThe role of serum testosterone levels in male renal stone formation remains controversial. This study aimed to evaluate the relationship between serum testosterone levels and kidney stone prevalence in males.MethodsWe conducted a cross-sectional study based on the data from the National Health and Nutrition Examination Survey 2011–2016, which included 6,633 male participants, to investigate the association between testosterone levels and the prevalence of kidney stones.ResultsIn this study, using the highest quartile of serum testosterone as a reference, a logistic regression model adjusted for confounders in all participants showed that the first quartile (OR: 1.375, p = 0.016), the second quartile (OR: 1.348, p = 0.021), and the third quartile (OR: 1.472, p = 0.003) of testosterone significantly increased kidney stone risks. In the 41–60 age group, the ORs of kidney stone risk in the first, second, and third of serum testosterone were 1.904 (P = 0.005), 1.599 (P = 0.040), and 1.734 (P = 0.015), respectively. This trend can also be found in the 61–80-year group, except in the first quartile of serum testosterone (OR: 1.169, P = 0.436). Adjusted smoothed curves suggest a non-linear relationship between the 8 quantiles of serum testosterone and the risk of kidney stones in all participants and the 61–80 age group and a significant negative relationship in the 41–60 age group (OR: 0.921, P = 0.0193). But no correlation was seen in the 20–40 group.ConclusionsSerum testosterone levels were significantly inversely associated with the prevalence of kidney stones in men over 40 years of age, but no correlation was seen in the 20–40 group. The role of testosterone in stone formation should be redefined, and its effect should be further verified.

BackgroundParticipant engagement with program interventions is vital to support intended behaviour changes and outcomes. The aim of this research was to investigate participant engagement with the Communicating Healthy Beginnings Advice by Telephone (CHAT) program, an early childhood obesity prevention program that included interventions for promoting healthy infant feeding practices and obesity-protective behaviours via telephone, and whether engagement with the telephone support program varied by participants’ sociodemographic characteristics.MethodsThis study used de-identified CHAT program data of participants who received the interventions via telephone. Data analysed included 1) participant engagement in telephone support from late pregnancy to 12 months of child's age, 2) demographic characteristics collected at late pregnancy and 3) intervention providers’ observations and notes (qualitative data) for 10 participants from each engagement group (low, medium, high) to explore issues discussed during telephone support.ResultsCall completion rate by participants was above sixty percent for all six stages of the telephone support program with more than half of the participants (57%) demonstrating high level of engagement. We found that participants’ country of birth, employment status and annual household income were predictors of engagement with the telephone support provided in the CHAT program. The odds of participants’ engagement with the telephone support program were 1.68 times higher for Australian born (95% CI 1.07 – 2.62), 1.63 times higher for participants who were employed (95% CI 1.01 – 2.66) and 1.63 times higher for participants with annual household income ≥AUD$80,000 (95% CI 1.02 – 2.60).ConclusionsParticipant engagement with the program interventions was good. Participants’ engagement with the telephone support program was significantly associated with certain socio-demographic characteristics. Australian born participants, and participants associated with higher household income and employment engaged significantly more with the telephone support provided in the CHAT program. Additionally, the program engaged more participants older than 30 years of age and those who spoke English at home. The program provided unintended personal benefits to some participants with high engagement level due to their various psychosocial needs such as domestic violence, mental health and sleep related issues. Although not an intended benefit of the intervention, psychosocial needs of participants were met which was a likely factor for mothers’ engagement with the program. This is an important factor that needs to be considered while implementing future programs or scale up of this program.
Cluster Partition-Based Zonal Voltage Control for Distribution Networks With High Penetrated PVs

Published: May 2022

With the high penetrated photovoltaics (PVs) accessing distribution networks (DNs) in the future, the overvoltage of distribution network will be more serious, and the voltage control will be more complex. To solve this problem, a cluster partition-based zonal voltage control method for DN is proposed in this study. First, a cluster partition method using a comprehensive performance index is proposed: in terms of DN structure, a global density quality function index is introduced to measure the coupling degree of nodes in clusters. In terms of cluster function, the inconsistency coefficient index is presented to reflect the PV output characteristics, and a node membership function index is presented to limit the scale of the cluster. Then, the DN cluster partition is carried out under the fast Newman (FN) algorithm. Second, a second-order cone programming (SOCP) model of voltage control is established to maximize the PV consumption in each cluster. To achieve the coordinated optimization of clusters, an iterative optimization strategy among clusters is proposed. Finally, the effectiveness and rationality of the proposed method are verified in a 10 kV actual feeder system in Zhejiang Province, China.

Published: May 2022

Heterogeneous photocatalysis is a highly efficient process for degrading recalcitrant and emerging pollutants. Rhodamine B (RhB) is a nonbiodegradable and highly refractory compound persistent in conventional processes. In this work, we investigate the photocatalytic activity of gallium-based catalysts undoped (GO) and doped with Fe ions (GOFe). Catalysts were synthesized by simple precipitation assisted with an ultrasonic transducer and subjected to thermal treatment at different temperatures (500, 650, 800 and 950°C). They were characterized by thermogravimetric analysis (TGA), Fourier transform infrared (ATR-FTIR) spectroscopy, and X-ray diffraction (XRD). Catalysts were tested in the discoloration of Rhodamine B dye. Experiments were carried out at different pH values (3.00, 5.00 and 9.00) in the presence of H2O2 and using Visible and Visible-UV light sources as study variables. Better discoloration results were observed for GO and GOFe under acid environments (pH = 3.00) for both light sources. GO and GOFe photocatalyst showed high effectiveness in the discoloration of RhB completing the process in 300  min, under a Visible-UV lamp at pH = 3.00. Incorporating Fe ions into the gallium oxides matrix decreases its bandgap, allowing it to activate under visible light. The discoloration process exhibited pseudo-zero-order apparent kinetics.
