Energy Efficiency of Opportunistic Refreshing for Gain-Cell Embedded DRAM

On-die memories, which are traditionally implemented by SRAM, stop functioning properly when the supply voltage is scaled down aggressively; hence, embedded DRAMs (eDRAMs) are used instead. Opportunistic refreshing was proved to eliminate the performance loss incurred by the eDRAM refreshing must. We show here that Gain-Cell eDRAM (GCeDRAM) supplemented with opportunistic refreshing consumes significantly smaller power and energy than SRAM. Analysis supported by hardware simulations demonstrate that the same design point achieves maximum performance and minimum energy. Replacement of the data memory in the ultra-low power processor PULPino from SRAM to opportunistically refreshed GCeDRAM yielded 30% energy savings in the memory, which translated into 7% savings in the entire processor.
Wideband tunable high-power narrow-linewidth erbium-ytterbium-doped fiber laser using compression-tunable fiber Bragg grating

We demonstrate a high power erbium-ytterbium co-doped large-core fiber laser with narrow linewidth, an M2 value of 1.7 and a broad tuning range. The fiber was cladding-pumped by a diode stack emitting at 975 nm. The laser had a linewidth around 0.16 nm and was tuned from 1533 nm to 1566 nm by compression-tuning a fiber Bragg grating. Output powers in excess of 30 W were obtained over the entire laser tuning range which was limited by the low gain at wavelengths shorter than 1533 nm and by the grating fabrication wavelength at 1566 nm. The laser slope efficiency was ~30% and the threshold ~3.3 W. Our results underline the capability for efficient, broad-band, high-power operation of large-core Er-Yb doped fibers and demonstrate compatibility with telecom components like standard single-mode fibers and fiber Bragg gratings.
Mitochondrial DNA sequence analysis of Arabibarbus grypus (Heckel, 1843) living in Great Zab (Erbil, Iraq)

Arabibarbus grypus (Heckel, 1843), which naturally lives in the Euphrates and Tigris River systems and is endemic, is an economically important fish species consumed by humans. Since the population of this species, which is hunted by both fishermen and local peo-ple, is decreasing day by day, its genetic characteristics need to be determined. This study aims to determine the genetic characteristics of A. grypus samples living in Great Zab based on sequence analysis of mtDNA cyt b and mtDNA d loop gene regions. Total DNA isolation was performed from muscle tissue using the kit. Then, Polymerase Chain Reac-tion was applied through spe-cific primers to mtDNA cyt b and mtDNA d loop gene re-gions, and the target regions were amplified. The products with the target length were sent to the commercial firm and sequence analysis was per-formed. Regarding these spec-imens living in Great Zab, two haplotypes were determined for the mtDNA cyt b gene re-gion and five haplotypes for the mtDNA d loop gene re-gion. These haplotypes were compared with the haplotypes in the gene bank and the re-sults were evaluated. Some important data has been ob-tained regarding the conserva-tion and management of this fish species. Since three new haplotypes were detected for the d loop region in this stud-ied locality, it is important to include the samples in this lo-cality in conservation studies.
The Luminosity Function for the CfA Redshift Survey Slices

La fonction de luminosite est calculee pour 2 parties completes de l'extension du survey des redshifts CfA. La forme de cette fonction peut etre approximee par une fonction de Schechter et on montre qu'une technique non parametrique derivee par Lynden-Bell et Turner peut fournir une estimation non biaisee de la forme de la fonction de luminosite. Deux estimateurs differents sont utilises pour determiner l'amplitude de la fonction de luminosite. Les effets du biais de Malmquist sur un survey des redshifts limite en magnitude sont discutes. On montre que les erreurs aleatoires dans les magnitudes affectent a la fois la determination de la fonction de luminosite et le contraste de la densite spatiale des structures a grande echelle. L'amplitude de ces biais est calculee en supposant une repartition gaussienne pour les erreurs
Gait Rehabilitation in Ambulant Diplegic Children Using Botulinum A Injection and Ankle Weights

Objectives Standing and walking serve an individual's basic needs to move from place to place, and both are the most common activities that people do daily. So, this study aims to investigate the combined effect of botulinum A injection and ankle weight on excessive knee flexion in diplegic children with crouch gait. Methods Sixty children with spastic diplegia walking with a crouch gait were included in this study. They were divided equally into three groups (twenty in each): group A received classical gait rehabilitation, group B received the same gait training while adding ankle weights, and group C received the same as group A and B plus botulinum A injection. The modified Ashworth scale (MAS) and Hoffman reflex/Myogenic response (H/M ratio) were used to evaluate the spasticity of the hamstring and gastrocnemius muscles, while two-dimension gait analysis was used to record knee flexion angles during gait. The assessment was held one day before starting the treatment and after completing three months of the treatment program. Results There was no significant difference between groups before treatment regarding all measured variables. group A revealed a statistically nonsignificant improvement after treatment. Patients in group B showed significant improvement after treatment for both knees regarding the H/M ratio and MAS, which was reflected in the right and left knee range of motion at initial contact (P values 0.030 and 0.001, respectively) and midstance (P values 0.030 and 0.006, respectively). However, more significant improvement was detected regarding all studied variables in both knees after treatment in group C patients with a P value <0.001. Conclusion The combination of botulinum A injection and ankle weights was more effective in controlling excessive knee flexion in diplegic children with a crouch gait.
Pengaruh Word Affect Intensities Terhadap Deteksi Ulasan Palsu

Transaksi jual beli elektronik melalui internet terus berkembang dan menjadi populer, begitu pula dengan jumlah ulasan dari pelanggan yang meningkat pesat. Dengan banyaknya pemberi ulasan, terdapat kemungkinan seseorang menulis ulasan palsu yang disebut fake review untuk mempromosikan produk atau menjatuhkan produk kompetitor. Sangat penting untuk dapat mendeteksi ulasan palsu sehingga ulasan yang digunakan pelanggan sebagai pertimbangan untuk memilih produk atau jasa merupakan ulasan yang andal. Studi sebelumnya hanya menggunakan fitur sentimen yang terbatas pada objektivitas dan polaritas untuk melakukan deteksi ulasan palsu. Sedangkan studi yang lebih baru menunjukan adanya leksikon kosa kata berbasis emosi yang diberi nama word affect intensities yang terbukti mampu mengukur sentimen dengan lebih baik pada kalimat. Penelitian ini bermaksud untuk mengetahui apakah word affect intensities dapat menjadi faktor yang mempengaruhi hasil deteksi ulasan palsu. Penelitian dilakukan dengan memunculkan dua fitur baru berlandaskan word affect intensities berupa fitur kelompok emosi positif dan fitur kelompok emosi negatif. Fitur tersebut kemudian dikombinasikan dengan fitur pada penelitian sebelumnya dan dievaluasi menggunakan beberapa algoritme klasifikasi. Hasil penelitian menunjukan word affect intensities dapat menjadi faktor yang mempengaruh peningkatan akurasi deteksi ulasan palsu sebesar 2.1%. Abstract Electronic buying and selling transactions over the internet continue to grow and become popular, as well as the number of reviews from customers that is increasing rapidly. With so many reviewers, it is possible that someone wrote a fake review to promote a product or demote a competitor’s product. It is very important to be able to detect fake review so that the reviews customers use as a consideration for choosing a product or service are reliable reviews. Previous studies only used sentiment features that were limited to objectivity and polarity to detect fake review. Meanwhile, a more recent study shows that there is an emotion-based vocabulary lexicon called word affect intensities which are proven to be able to better measure sentiment in sentences. This study intends to determine whether word affect intensities can be a factor that affects the results of fake review detection. The research was conducted by bringing up two new features based on the word affect intensities in the form of positive emotion group features and negative emotion group features. These features are then combined with features in previous studies and evaluated using several classification algorithms. The results showed that word affect intensities can be a factor that affects the increased accuracy of fake review detection by 2.1%.
Pollution Load Capacity in the Downstream Citarum Watershed: 4 years after Citarum Harum Program

Citarum River is one of the strategically valuable rivers in Indonesia, especially on Java Island. Since 2018, the central government has carried out the "Citarum Harum" program to revitalize the river while improving its reputation of Citarum as one of the dirtiest rivers in the world. This study aimed to see the pollution load capacity of the downstream Citarum River 4 years after the revitalization program was implemented. Downstream Citarum Watershed (Karawang Regency) was chosen as the focus of the study site because of the very high risk of contamination. This research was comparing the pollution load capacity of biochemical oxygen demand (BOD) in 2022 using Qual2Kw software and 2017 based on the data analyzed by the Ministry of Environment and Forestry. River revitalization over the last 4 years has significantly reduced the BOD value in the downstream Citarum Watershed. The success of this revitalization program can be a reference for other watershed management toward environmental improvement using the same scheme. This study is expected to provide updated information on water quality in the downstream Citarum watershed several years after revitalization and provide an overview of the important functions of river revitalization
The Impact of Dispositional Mindfulness (DM) on Sports Injury Recovery Time

This study analyzes the underlying relationship between dispositional mindfulness (DM) and sports injury recovery time. Sports injuries in high intensity sport are extremely detrimental to both the athlete’s performance and psychological well-being. Consequently, the role of trainers/clinicians and rehabilitation programs are extremely important as they determine the injury recovery time of the athletes. Though physical therapies have shown to be effective in reducing the injury recovery time of an athlete, the addition of more psychological practices, such as that of DM, could furthermore decrease sports injury recovery time. Through analyzing studies regarding the relationship between DM and sports injury recovery time, it is shown that DM can positively affect those going through injuries and can assist them in getting back onto the pitch in a speedier manner.
Reductions to Korteweg-de Vries Soliton Hierarchy

Based on the nonlinearization of Lax pairs, the Korteweg-de Vries (KdV) soliton hierarchy is decomposed into a family of finite-dimensional Hamiltonian systems, whose Liouville integrability is proved by means of the elliptic coordinates. By applying the Abel–Jacobi coordinates on a Riemann surface of hyperelliptic curve, the resulting Hamiltonian flows as well as the KdV soliton hierarchy are ultimately reduced into linear superpositions, expressed by the Abel–Jacobi variables.
Indoor Visual Re-Localization for Long-Term Autonomous Robots Based on Object-Level Features and Semantic Relationships

Visual re-localization has become one of the key technologies for long-term autonomous robots. Existing methods, mostly focusing on addressing day-night, weather, and seasonal changes, are not applicable in indoor scenarios. At the same time, the layouts of objects in indoor scenes are highly dynamic over time due to human interactions with the environment, which makes indoor re-localization challenging. This letter presents a novel indoor visual re-localization method for long-term autonomous robots. First, a scene graph model is proposed, incorporating object-level features and semantic relationships, which overcomes the influence of dynamic objects by understanding the interactions among objects. Then, a visual re-localization method is developed based on the proposed scene graph model. It adopts graph matching technologies to incorporate pairwise object interactions as important features for re-localization, and designs a feature reweighting strategy to further reduce the impact of outliers in dynamic scenes. The proposed re-localization method has been verified in both photorealistic simulation environments and real-world scenarios. The results show that our approach exhibits higher robustness to diverse object changes and performs comparably to the state-of-the-art methods when illumination changes occur.
A starting-point strategy for interior-point algorithms for shakedown analysis of engineering structures

Lower-bound shakedown analysis leads to nonlinear convex optimization problems with large numbers of unknowns and constraints, the solution of which can be obtained efficiently by interior-point algorithms. The performance of these algorithms strongly depends on the choice of the starting point. In general, starting points should be located inside the feasible region. In addition, they should also be well centred. Although there exist several heuristics for the construction of suitable starting points, these are restricted, as long as only the mathematical procedure is considered without taking into account the nature of the underlying mechanical problem. Thus, in this article, a strategy is proposed for choosing appropriate starting points for interior-point algorithms applied to shakedown analysis. This strategy is based on both the mathematical characteristics and the physical meaning of the variables involved. The efficiency of the new method is illustrated by numerical examples from the field of power plant engineering.
Explosions in Wolf-Rayet stars and type Ib supernovae. I: Light curves

Numerical models of core-bounce SN with hydrogenless W-R progenitors have been obtained. The luminosity near peak light of these SN is attributed to the escape of radioactive decay energy which accumulates in the optically thick interior and diffuses outward until it meets the inwardly moving photosphere. Although the present models cannot explain the observed decline in luminosity immediately after peak in SN 1983N, they may be able to fit the light curve of SNIb 1985F. 94 references.
FSP-1 expression in cancer cells is relevant to long-term oncological outcomes in nonmetastatic colorectal cancer

Purpose Recent studies have revealed that the expression of cancer-associated fibroblast (CAF) activation biomarkers in cancer cells is associated with clinical outcomes in patients with certain types of malignant tumors. However, whether the expression of CAF activation biomarkers affects the prognosis of colorectal cancer (CRC) has not been fully elucidated. This study aimed to evaluate the association between the expression of CAF activation biomarkers in cancer cells with cancer invasion and long-term oncological outcomes in patients with CRC. Methods Cancer specimens obtained from 135 patients with stage I–III CRC were examined using immunohistochemical staining to evaluate the expression of fibroblast specific protein-1 (FSP-1), fibroblast activation protein α (FAPα), α-smooth muscle actin (α-SMA), and vimentin in cancer cells. Results FSP-1 expression in cancer cells was significantly associated with lymphatic invasion, perineural invasion, tumor (T) status, and lymph node (N) status. FAPα expression in cancer cells was significantly associated with lymphatic invasion. On univariate and multivariate analyses, FSP-1 and α-SMA expression in cancer cells were associated with a short 10-year overall survival (OS) and high 10-year systemic recurrence (SR), respectively. Tumor budding was associated with a short 10-year OS. However, FAPα and vimentin did not contribute to the prognosis in this study. Conclusion In this study, we found that FSP-1 expression in cancer cells was related to cancer invasion. Additionally, FSP-1 and α-SMA expression in cancer cells was associated with 10-year OS and SR, respectively. Therefore, these markers may be used as predictors of long-term oncological outcomes in patients with CRC.
Experimental verification of broadband invisibility using a cloak based on inductor-capacitor networks

We demonstrate the experimental realization of an invisibility cloak based on inductor-capacitor (L-C) transmission line (TL) networks. The anisotropic medium parameters of a cloak in the cylindrical basis are controlled independently by three branches of the L-C unit cell, which leads to a full-parameter realization of the cloak. A cylindrical cloak working in very-high-frequency band has been designed and fabricated, with its performance measured. The nonresonant property of the TL structure results in a relatively broad bandwidth (from 24 to 40 MHz) of the realized cloak, which is clearly observed in our experiment.

Cars Tracking and Counting at Night

This work proposes a robust scheme to automatically tracking and counting cars in the traffic surveillance. In the proposed method, pixels at a specific position of successive image frames are first processed by the modified iterative threshold selection technique to establish the background model. Second, an original image is subtracted by this background to obtain a difference image that is performed with the differential image between an original image and its precedent neighboring image to yield an image with initial contour points of moving objects. Third, the robust edge-following scheme manipulates these contour points to produce closed-form objects. Particularly, two headlights of a car are merged with their corresponding reflective lights on the ground to yield two light objects for a car extraction at night. As compared to the conventional methods, the proposed method is demonstrated to have the best accuracy of moving object extraction. Finally, object motion connection is effectively employed to track object paths and compute the number of moving cars. The practical implementation reveals that the proposed method can precisely and reliably estimate a traffic amount.
Impact of Nanoparticles on Male Fertility: What Do We Really Know? A Systematic Review

The real impact of nanoparticles on male fertility is evaluated after a careful analysis of the available literature. The first part reviews animal models to understand the testicular biodistribution and biopersistence of nanoparticles, while the second part evaluates their in vitro and in vivo biotoxicity. Our main findings suggest that nanoparticles are generally able to reach the testicle in small quantities where they persist for several months, regardless of the route of exposure. However, there is not enough evidence that they can cross the blood–testis barrier. Of note, the majority of nanoparticles have low direct toxicity to the testis, but there are indications that some might act as endocrine disruptors. Overall, the impact on spermatogenesis in adults is generally weak and reversible, but exceptions exist and merit increased attention. Finally, we comment on several methodological or analytical biases which have led some studies to exaggerate the reprotoxicity of nanoparticles. In the future, rigorous clinical studies in tandem with mechanistic studies are needed to elucidate the real risk posed by nanoparticles on male fertility.
Overview of frequent pattern mining

Various methods of frequent pattern mining have been applied to genetic problems, specifically, to the combined association of two genotypes (a genotype pattern, or diplotype) at different DNA variants with disease. These methods have the ability to come up with a selection of genotype patterns that are more common in affected than unaffected individuals, and the assessment of statistical significance for these selected patterns poses some unique problems, which are briefly outlined here.
Extensions of Type G and Marginal Infinite Divisibility

We say that a random variate on a Euclidean space is marginal infinitely divisible with respect to a class of linear mappings on that space if each of these mappings results in an infinitely divisible random variate. Special cases are applied in a multivariate extension of the concept of type G probability laws. Random nonnegative matrices play a central role.
Polarization-matched GaInN∕AlGaInN multi-quantum-well light-emitting diodes with reduced efficiency droop

Blue multi-quantum-well light-emitting diodes (LEDs) with GaInN quantum wells and polarization-matched AlGaInN barriers are grown by metal-organic chemical vapor deposition. The use of quaternary alloys enables an independent control over interface polarization charges and bandgap and has been suggested as a method to reduce electron leakage from the active region, a carrier loss mechanism that can reduce efficiency at high injection currents—an effect known as the efficiency droop. The GaInN∕AlGaInN LEDs show reduced forward voltage, reduced efficiency droop, and improved light-output power at large currents compared to conventional GaInN∕GaN LEDs.
