Unsupervised person re‐identification based on adaptive information supplementation and foreground enhancement
Authors: Wang Qiang , Huang Zhihong , Fan Huijie , Fu Shengpeng , Tang Yandong 
Published: November 2024

AbstractUnsupervised person re‐identification has attracted vital interest because of its ability to protect privacy, significantly lower the expense of manual annotation, and eliminate the need for data labels. General unsupervised methods train the network only through global features, which causes the fine‐grained information contained in local features to be ignored in the recognition process, resulting in large amounts of label noise and affecting the recognition accuracy. Moreover, more robust pedestrian features can also improve the accuracy of clustering and enable unsupervised person re‐identification to obtain better results. To address these issues, first, a dual‐branch structure was proposed, which separately obtains the global features of the pedestrian and the local features by dividing the global features into a few equal sections. Then, an adaptive information supplementation (AIS) method based on the k‐nearest neighbor algorithm is designed to ascertain each local feature's relevance to the global features, calculating adaptive weight scores for information supplementation. Finally, these weight scores are used to reallocate the weights of the global features in each part, acquiring features that contain more pedestrian information during the representation learning process. These better features are used to reduce label noise to obtain more accurate pseudo‐labels. Second, an adaptive foreground enhancement module (AFEM) was proposed and inserted before clustering to increase the robustness of pedestrian features, which increases the precision of the pseudo‐labels that are produced after clustering. Experiments on Market‐1501, DukeMTMC‐reID, and MSMT17 demonstrate that the proposed method achieves better results than state‐of‐the‐art methods in fully unsupervised person re‐identification tasks.

Published: November 2024

AbstractA hybrid‐three‐level isolated dual‐active‐bridge (HTDAB) DC–DC converter is widely used for grid‐interactive power converters. However, a traditional extended‐phase‐shift (EPS) modulation scheme would cause voltage‐level‐disorder (VLD) problems in HDAB DC–DC converter system because the output voltage of HTDAB would be clamped at a high‐ or low‐level during power transmission when the inductor current changes directions. Thus, the zero voltage sequence of the HTDAB cannot be stably maintained under EPS control, which not only leads to a significant difference between the actual transmission power and the target output power but also seriously affects the stability of the system control. To address this limitation, the reasons leading to VLD are analysed in detail, that is, an inappropriate PWM switching sequence at the output zero voltage level would occur under EPS control. Then, a novel PWM plus phase shift (PPS) modulation strategy is proposed, which can eliminate VLD completely. Finally, an experimental prototype is built to verify the effectiveness of the proposed PPS modulation scheme. The experimental results demonstrate that the PPS modulation method proposed in this article can effectively eliminate level disturbances and improve system stability.
A fast hysteresis analysis based on neural network and play model
Authors: Jibiki Takuto , Igarashi Hajime 
Published: November 2024

AbstractThis paper presents a fast hysteresis loss analysis method based on neural network, which predicts the hysteresis loss from the waveform of the magnetic flux density in a magnetic core. The hysteresis loss data used to train the neural network is computed using the play model which can accurately account for hysteresis characteristics such as minor loops and DC bias. The proposed method can perform loss analysis 2,000 times faster than conventional methods. The proposed method is highly effective when harmonic components are superimposed on the input waveforms and when loss analysis is performed for a large number of different waveforms.

Published: November 2024

Objectives This retrospective study aims to elucidate the clinical associations of HPV-16, HPV-18, and p16 expression with clinicopathological parameters, risk behaviors, and survival outcomes in head and neck cancer patients from the western Indian population.
Methods Clinical data of total 92 enrolled HNC patients diagnosed between years 2021 and 2023 were retrospectively collected from medical records. Formalin-fixed, paraffin-embedded blocks of all enrolled patients were collected whose p16 expression by immunohistochemistry tests were already performed. HPV-16 and HPV-18 infection was studied by real-time polymerase chain reaction. Associations between viral status, p16 expression, clinicopathological parameters, risk behaviors, and survival outcomes were assessed using SPSS statistical software version 20. p-Value ≤0.05 was considered to be statistically significant.
Results Among the 92 enrolled HNC patients, HPV-16 infection was detected in only 12 (13%) patients, with the remaining 80 (87%) testing negative. No HPV-18 infections were observed in any patient. Additionally, p16 expression was positive in only 13 (14%) patients, while 79 (86%) showed negative expression. A statistically significant correlation was found between metastasis involvement and positive HPV-16 infection (p < 0.001), with all HPV-16-positive cases exhibiting metastasis. A trend was also noted between the base of tongue and other clinical site subtypes with positive HPV-16 infection (p = 0.063). However, no other clinicopathological or risk behaviors showed significant associations with HPV-16 infection and p16 expression. Overall survival analysis revealed that neither HPV-16 infection nor p16 expression served as significant prognosticators in the HNC patient cohort (p > 0.05).
Conclusion This study provides comprehensive insights into the clinical relevance of HPV-16, HPV-18 infections, and p16 expression in HNC among the western Indian population. Understanding the associations between HPV-16, HPV-18, and p16 expression with clinicopathological parameters and survival outcomes may aid in optimizing patient management strategies, including personalized treatment approaches and targeted interventions. Further prospective studies are warranted to validate these findings and explore potential therapeutic implications.
Vietnamese transitive cognate objects revisited
Authors: Phan Thao Trang Thi 
Published: November 2024

Abstract
A cognate object construction (COC) is a construction in which a typically intransitive verb combines with a nominal phrase that has the same meaning or the same morphological stem, e.g., live a happy life. In the literature, the syntactic status of cognate objects (CO) is one of the most debated issues. Pham (1999) observes that in Vietnamese, COs can occur with transitive verbs in both the direct object and indirect object position. She concludes that examples of direct COs provide evidence for the view that COs are arguments, and the existence of indirect COs shows that they can also be indirect objects. First, this paper argues that direct COs cannot be treated as evidence for the argument status of COs since they are not additional arguments. Moreover, they are not nouns but classifiers. Second, indirect COs are not indirect objects but prepositional objects in an adverbial prepositional phrase. These findings reveal that Vietnamese transitive COs are complex and different from the description in Pham’s study. It is important to make a clear distinction between these transitive COs and intransitive COs, especially in cross-linguistic research.
On the orthography of Philippine Creole Spanish in Zamboanga
Authors: De Castro Gefilloyd L. 
Published: November 2024

Abstract
This article aims to demonstrate the critical importance of corpus-driven language standardization and linguistic
expertise in orthography development using Zamboanga Chavacano (henceforth ZC) as a case study. I aim to highlight the
inconsistencies between the official orthography and actual usage and make a case for corpus-driven language planning in the
development of creole orthographies by analyzing the current official orthography of ZC. Specifically, I will present what the
orthographic system of ZC should look like if corpus planning had played a role in the development of the official and standard
orthography of ZC. This note discusses this issue based on an analysis of the Contemporary Written Zamboanga Chabacano Corpus
(CWZCC) compiled by Himoro (2019) and compares the practices that emerge from the
corpus with those used in the officially approved orthography. CWZCC is a comprehensive corpus, consisting of 8,038,200 words from
radio scripts, newspapers, news articles, literary pieces (i.e., songs, poems, short stories), public and government documents,
certificates, educational materials (e.g., Chavacano lessons in the MTB-MLE), public and commercial signs and/or advertisements,
and campaign materials such as posters and tarpaulins, Facebook posts and comments, Twitter posts and comments, blogs, and online
forums. The AntConc version 3.5.9, a freeware corpus analysis toolkit for concordance and text analysis was utilized to establish
the word list from the CWZCC. The spelling variants were manually determined and arranged according to the frequency of
occurrences.
The interaction of syntax, non-manuals, and prosodic cues as potential topic markers in Austrian Sign
Language
Authors: Krebs Julia , Wilbur Ronnie B. , Roehm Dietmar , Malaia Evie A. 
Published: November 2024

Abstract
Topic is often marked only by prosody across languages. In sign languages, prosody is expressed by features
similar to those in speech: i.e., sign duration, velocity and amplitude of movement (cf. slope and range of pitch). Topicalized
signs usually occur sentence-initially, are followed by a pause, and may show longer duration than nontopics. We used pausing and
duration characteristics to resolve a puzzle concerning the status of OSV sentences in Austrian Sign Language (ÖGS): are they a
nonmanually unmarked variant of non-manually marked topic sentences (O,SV), or are they a within-clause variant of the basic SOV
order serving an as-yet-unknown discourse function? We investigated the temporal parameters of prosodic cues of 160 sentences
produced by a fluent ÖGS signer: 40 in each of four conditions — SOV, OSV, S,OV, and O,SV. Overt topic marking effects on signing
dynamics consisted of (1) lengthening of the sentence-initial topic phrases, causing a delay of the onset of the argument
following the topic-marked item, and (2) a shortened duration of the noun phrase following the topic-marked item. Critically, the
initial argument of OSV sentences did not show these prosodic cues, indicating that the initial argument O is not treated as being
the same kind of topic as in the non-manually marked O,SV sentences. In accordance with the previous literature on pausing and
lack thereof, we suggest that OSV might be akin to spoken German scrambling (within-clause movement), although the function
performed remains to be investigated. The findings characterize parameters of temporal structure in the physical markers of topic
in ÖGS and point to cross-linguistic variability in prosodic marking for topicalized structures.

Authors: Pathak Ambika , Chhoker Sandeep 
Published: November 2024

Abstract
Current vivid study reports synthesis, optical studies of functional carbonaceous material (FCM) as well as broad range photoluminescence including synergistic effect of metallized porphyrin (as visible range light absorbing material) on photocatalysis carried under visible light irradiation. This high-order self-assembly of functional carbonaceous material possess extraordinary photophysical-chemical properties with its surface rich in functional groups (thus making it suitable for π-π
* transitions) and further its composite formation with a high absorption coefficient (more than 20,000 in broad visible range 400–700 nm) and non-radiative fluorescence quenching exhibiting (near IR) metallized porphyrin. The structural, compositional characteristics of FCM and its composite including phase purity, types of functional groups, bonding arrangement is analysed like XRD, FESEM, EDX, FTIR, UV–vis, FL and Raman spectroscopy. The optical as well as structural properties (exhibiting suitable ID/IG ratio ∼ 1.4) of the pure as well as composite of FCM and porphyrin (band gap shifting from UV (4.2 eV) to visible (3.0 eV)) indicated the robust and versatile behaviour to be explored in applications such as photodetection and catalysis. In this article, we report the broad range photoluminescence for pure FCM (300–550 nm) as well as its porphyrin-based composite (400–550 nm) and further the application of composite in the photocatalytic ability for the degradation of standard methylene blue dye for degradation percentage of 62% in 120 min in visible light while 30% in 180 min in dark. Its cost effectiveness, biocompatibility, solution processability, stability and the most crucial, its appreciable results in minute resource utilization indicates its appropriateness as competitive photocatalyst in similar as well as modified schemes.

Published: November 2024

Abstract
Fabrication of a (Y,RE)BCO superconducting compact simultaneous with improved properties is demonstrated using gelcasting of slurries into rapid prototyped precision moulds. The infiltration Growth (IG) process with NdBCO film seed was used to obtain a textured 45 mm long hollow superconducting (Y,RE)BCO cylinder, as a prototype. This involves design of a (Y,RE)2BaCuO5 preform referred to as (Y,RE)-211, into which liquid phase is infiltrated; this reacts with the preform and forms (Y,RE)Ba2Cu3O7-x. The end product aimed at is a composite of YBa2Cu3O7-x (YBCO) with 20 wt% of mixed rare earth (Nd,Sm,Gd)BCO and 0.5 wt% of WO3 nanoparticles, which are intended to cause notable enhancement in flux pinning and critical current density (J
c). Uniform distribution of micron-sized (Y/RE)-211 and WO3 nanoparticles in the matrix was enabled by sol-casting process. Magnetic shielding is demonstrated at low dc fields (41 gauss). J
c is found to remain nearly constant with field (B) at each temperature (T) up to 50 K, where J
c reaches about 4 kA cm−2 at 8.5 T. At 77 K, J
c of ∼ 4 kA cm−2 at zero field and ∼ 0.4 kA cm−2 at 8.5 T is observed. The flux pinning force density (F
p) increased with the applied field, reaching a maximum at a field (B
p) of 7 T to 8 T for all temperatures from 10 K to 77 K. Temperature-independent B
p confirms that flux pinning is caused by structural defects that induce fluctuations in the Ginzberg-Landau parameter (k). Substitution of RE ions randomly at the Y-site in YBCO unit cells can locally create compositional fluctuations that lead to stress fields and a dense network of stacking faults and assist pinning of flux. Analysis of F
p
(B) by scaling laws does confirm δk pinning to be the dominant mechanism. A second peak observed in F
p(B) curves at low fields, below 3 T, is attributed to additional pinning from WO3 nanoparticles and is field-dependent. Significance of the present process stems from the fact that it enables uniform distribution of second phase additions to be realized in the end product, for improved performance and it allows design and creation of components of composite ceramic superconductor in any complex shape, required for a chosen application.

Abstract
The current paper investigates the magnetohydrodynamic pulsating flow of micropolar nanofluid in a vertical porous channel by using Buongiornos nanofluid approach and utilizing entropy generation. The effects of thermal radiation, viscous dissipation, Brownian motion, and thermophoresis are considered. This finding holds implications for the fields of biomedical engineering, food processing systems, cancer treatment, pressure spikes, and nano-drug delivery in arteries. In this case, the governing partial differential equations (PDEs) are converted into ordinary differential equations (ODEs) using the perturbation approach and we used Runge-Kutta fourth order method for the numerical approach. Graphical representations illustrate the effects of nanoparticle concentration, velocity, temperature, and micro-rotation across various standard physical parameters. Furthermore, analysis and tabular presentation of the heat and mass transfer rates are provided. The data obtained indicate that while raising the Hartmann number and coupling parameter decreases velocity profiles then increasing the Grashof number enhances velocity. The temperature of a micropolar nanofluid rises with increased Brownian motion and thermophoresis, and falls with increased magnetic field and thermal radiation. The concentration of micropolar nanofluid is reducing by enhancing the thermophoresis and chemical reaction parameter. The rate of heat transfer is increasing as a result of increases in thermal radiation, viscous dissipation, thermophoresis, and Brownian motion values. The heat transfer rate rises with increase values of the viscous dissipation, thermal radiation, the Brownian motion, and the thermophoresis parameters. This study is useful for various real life applications like biological systems, biotechnology, pharmaceutical medicine, nano-drug development, and engineering industries.

Improving radiation resilience of zener diodes through preemptive and restorative electron wind force annealing

Published: November 2024

Abstract
Semiconductor devices contain defects and localized mechanical stress even in their pristine states, persisting after post-fabrication annealing. We hypothesize that these pre-existing conditions, with their lower threshold energy for defect proliferation and/or ionization, may serve as nuclei for radiation damage. To test this hypothesis, we adopted a two-pronged approach: (a) performing electron wind force (EWF) annealing preemptively on pristine Zener diodes to eliminate pre-existing defects before radiation exposure, and (b) applying EWF annealing restoratively on devices already damaged by radiation. The EWF process is non-thermal and can eliminate defects below 30 °C that persist through conventional thermal annealing. Both pristine and EWF-annealed pristine devices were exposed to 15 MeV protons with a fluence of 1014 cm−2. Radiation damage increased the ideality factor from 1 to 2.33 in the pristine devices, while the preemptively EWF-annealed devices showed remarkable resilience, with an ideality factor of 1.5. Similar performance improvements were observed with restorative EWF annealing on radiation-damaged devices. This resilience and recovery in performance are further supported by Raman spectroscopy indicating enhanced crystallinity compared to the pristine condition. These findings demonstrate the potential of EWF annealing as both a protective and restorative treatment for semiconductor devices in high-radiation environments.
Research on Adjustable Cold View Field Diaphragm in Optical System with Linear Array Detector in AIMS

Published: November 2024

Abstract
The infrared Fourier transform spectrometer needs a cold view field diaphragm to reduce stray radiation. For an infrared spectrometer with linear array detectors, the part of the view field diaphragm where the light passes can be regarded as a slit. If the infrared detectors are small in size, the width of the slit is also small, which will cause serious diffraction phenomena. If the widths of the view field diaphragm and the optical system are designed by geometric optics theory, the diffraction light cannot be fully received by the detectors, which will cause energy loss. Expanding the width of the view field diaphragm will introduce stray radiation. Meanwhile, spectrometer follow-up optics should be set in cold environments to reduce the infrared background of the instrument. Optical materials have different thermal characteristics, the optical and mechanical structures will deform at low-temperature, and the cold view field diaphragm is installed at room temperature, so it is impossible to guarantee that the cold view field diaphragm remains in its design position when working at low-temperature. This paper solves the above problems by designing an adjustable cold view field diaphragm installed in its cryogenic vacuum chamber. The width and position of the view field diaphragm can be adjusted when working in cold temperatures, without opening the cryogenic vacuum chamber. Contrasting the interference signal obtained by the detectors in the adjustment process, the system can get the most suitable width and position of the cold view field diaphragm. The above works are based on the spectrometer used in the study named Accurate Infrared Magnetic Field Measurements of the Sun.
