Published: February 2021

AbstractThis paper reviews recent research works in infant cry signal analysis and classification tasks. A broad range of literatures are reviewed mainly from the aspects of data acquisition, cross domain signal processing techniques, and machine learning classification methods. We introduce pre-processing approaches and describe a diversity of features such as MFCC, spectrogram, and fundamental frequency, etc. Both acoustic features and prosodic features extracted from different domains can discriminate frame-based signals from one another and can be used to train machine learning classifiers. Together with traditional machine learning classifiers such as KNN, SVM, and GMM, newly developed neural network architectures such as CNN and RNN are applied in infant cry research. We present some significant experimental results on pathological cry identification, cry reason classification, and cry sound detection with some typical databases. This survey systematically studies the previous research in all relevant areas of infant cry and provides an insight on the current cutting-edge works in infant cry signal analysis and classification. We also propose future research directions in data processing, feature extraction, and neural network classification fields to better understand, interpret, and process infant cry signals.
Shortened LDPC codes accelerate OSD decoding performance
Authors: Watanabe Kohtaro , Kaguchi Ryusei , Shinoda Toshiya 
Published: February 2021

AbstractMedium-length LDPC codes are in demand in certain areas such as mobile environment (Wi-Fi and Mobile WiMAX) and in telecommand links from the ground to space because of their lower latency properties. However, because of the length of these codes is rather short, decoding error rates are worse than those of long-length codes. In this paper, we show that the combination of shortened LDPC codes, whose shortened positions are properly selected, and ordered statistic decoding (OSD) significantly improves the decoding error. For the best choice of shortening positions, we used the integer programming approach. In particular, we utilized Feldman–Wainwright–Karger code polytope for this purpose. Some studies have independently reported the efficiency of shortened LDPC codes and OSD methods. This paper emphasizes that their combination results in multiplicative effectiveness.

Published: February 2021

Abstract
Background
Hypothermic machine perfusion (HMP) improves the quality of donor livers for transplantation, both in animal models and in clinical practice. Treatment with SP600125, an inhibitor of c-Jun N-terminal kinase (JNK), can suppress the JNK signaling pathway to alleviate donor liver ischemia–reperfusion injury (IRI). We performed the present study with the objective of exploring the protective effects exerted by a combination of HMP and SP600125 on liver xenograft viability for donation after cardiac death (DCD) in a porcine model.

Methods
54 adult BAMA mini-pigs were randomly assigned to 5 groups, including sham, cold storage for 4 h (CS 4 h), CS 4 h + SP600125, CS 2 h + HMP 2 h, and CS 2 h + HMP 2 h + SP600125 groups. Donor livers in the CS 4 h and CS 4 h + SP600125 groups were conventionally cold preserved for 4 h, whereas donor livers in the CS 2 h + HMP 2 h and CS 2 h + HMP 2 h + SP600125 groups were cold preserved for 2 h and then treated with HMP for 2 h. The preservation and perfusion solutions contained SP600125 (20 µM). Follow-up was conducted for 5 days after liver transplantation to compare the surgical outcomes by means of serological examination, pathological results, and survival rate.

Results
The most satisfactory outcome after liver transplantation was observed in the CS 2 h + HMP 2 h + SP600125 group, which presented with minimal damage of donor livers during 5 days’ follow-up. Additionally, serological examination, pathological results, and survival rate concurred in showing better results in the CS 2 h + HMP 2 h ± SP600125 group than in the CS 4 h ± SP600125 group.

Conclusion
HMP in combination with SP600125 has hepatoprotective properties and improves the quality and viability of porcine livers collected after DCD, thus improving prognosis after liver transplantation.
The effect of GPS refresh rate on measuring police patrol in micro-places
Authors: Hutt Oliver K. , Bowers Kate , Johnson Shane D. 
Published: February 2021

AbstractWith the increasing prevalence of police interventions implemented in micro hot-spots of crime, the accuracy with which officer foot patrols can be measured is increasingly important for the robust evaluation of such strategies. However, it is currently unknown how the accuracy of GPS traces impact upon our understanding of where officers are at a given time and how this varies for different GPS refresh rates. Most existing studies that use GPS data fail to acknowledge this. This study uses GPS data from police officer radios and ground truth data to estimate how accurate GPS data are for different GPS refresh rates. The similarity of the assumed paths are quantitatively evaluated and the analysis shows that different refresh rates lead to diverging estimations of where officers have patrolled. These results have significant implications for the measurement of police patrols in micro-places and evaluations of micro-place based interventions.

Abstract
Background
Primary graft dysfunction (PGD) remains a major obstacle after lung transplantation. Ischemia–reperfusion injury is a known contributor to the development of PGD following lung transplantation. We developed a novel approach to assess the impact of increased pulmonary blood flow in a large porcine single-left lung transplantation model.

Materials
Twelve porcine left lung transplants were divided in two groups (n = 6, in low- (LF) and high-flow (HF) group). Donor lungs were stored for 24 h on ice, followed by left lung transplantation. In the HF group, recipient animals were observed for 6 h after reperfusion with partially clamping right pulmonary artery to achieve a higher flow (target flow 40–60% of total cardiac output) to the transplanted lung compared to the LF group, where the right pulmonary artery was not clamped.

Results
Survival at 6 h was 100% in both groups. Histological, functional and biological assessment did not significantly differ between both groups during the first 6 h of reperfusion. injury was also present in the right native lung and showed signs compatible with the pathophysiological hallmarks of ischemia–reperfusion injury.

Conclusions
Partial clamping native pulmonary artery in large animal lung transplantation setting to study the impact of low versus high pulmonary flow on the development of ischemia reperfusion is feasible. In our study, differential blood flow had no effect on IRI. However, our findings might impact future studies with extracorporeal devices and represent a specific intra-operative problem during bilateral sequential single-lung transplantation.

Published: February 2021

AbstractThe wearable electronics integrated with textile-based devices is a promising strategy to meet the requirements of human comfort as well as electrical performances. This research presents a design and development framework for a seamless glove sensor system using digital knitting fabrication. Based on the performance requirements of glove sensors for controlling a prosthetic hand, desirable design components include electrical conductivity, comfort, formfit, electrical sensitivity, and customizable design. These attributes are determined and achieved by applying appropriate materials and fabrication technologies. In this study, a digital knitting CAD/CAM system is utilized to meet the desired performance criteria, and two prototypes of the seamless glove sensor systems are successfully developed for the detection of both human and robotic finger motions. This digital knitting system will provide considerable potential for customized design development as well as a sustainable production process. This structured, systematic approach could be adapted in the future development of wearable electronic textile systems.
IgG4-related gastric disease with plasma cell-rich obliterative arteritis accompanied by early-stage gastric cancer: a case report
Authors: Obatake Masayoshi , Sato Koichi , Yagi Shigehiko , Ohtani Hiromi , Kito Katsumi 
Published: February 2021

Abstract
Background
Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated inflammatory disorder that can involve multiple organs. It is characterized by IgG4-positive plasma cell-rich storiform fibrosis and obliterative phlebitis associated with a high serum IgG4 level. There are few reports of gastric IgG4-RD, especially those detected prior to systemic or other organ involvement.
Case presentation: A 70-year-old man was diagnosed with type 0–IIc gastric cancer at the anterior wall of the gastric corpus by upper gastrointestinal endoscopy. In addition, a submucosal tumor (SMT) 7 mm in diameter was found at the greater curvature of the angulus. Laparoscopic distal gastrectomy with regional lymph node dissection was performed. Pathology revealed a poorly differentiated adenocarcinoma in the type 0–IIc lesion and storiform fibrosis with infiltration of a large number of IgG4-positive plasma cells in the SMT. Postoperative laboratory testing showed elevation of serum IgG4 levels; thus, we diagnosed the SMT as IgG4-RD. Intriguingly, the gastric IgG4-RD lesion demonstrated IgG4-positive plasma cell-rich arteritis as well as typical obstructive phlebitis. The patient has been followed for 2 years after surgery without recurrence of cancer, but skin lesions of IgG4-RD have appeared.

Conclusion
We report a rare case of IgG4-RD presenting as a gastric SMT, accompanied by early-stage gastric cancer. Our case may support a newly proposed relationship between IgG4-RD and malignancies. The gastric IgG4-RD lesion showed arteritis as well as obliterative phlebitis, potentially providing novel insight into IgG4-related vascular lesions.
Stock prices and economic activity nexus in OECD countries: new evidence from an asymmetric panel Granger causality test in the frequency domain
Authors: Yilanci Veli , Ozgur Onder , Gorus Muhammed Sehid 
Published: February 2021

AbstractThis study investigates the stock price–economic activity nexus in 12 member countries of the Organization for Economic Cooperation and Development (OECD) by employing monthly data over the period 1981:1–2018:3. For this purpose, the study uses Granger causality in the frequency domain in the panel setting by decomposing the symmetric and asymmetric fluctuations. This methodology determines whether the predictive power of interested variables is concentrated on quickly, moderately, or slowly fluctuating components. Our findings show that the stock prices have predictive power for future long-term economic activity in the panel setting. However, economic activity has more reliable information for stock prices for negative components. Additionally, empirical findings for asymmetric shocks are not fully consistent with those of symmetric ones. Besides, the country-specific results provide different causal linkages across members and frequencies. These findings may provide valuable information for policymakers to design proper and effective policies in OECD countries regarding the stock market and economic activity nexus.
Effect of Ag nanoparticles on viability of MCF-7 and Vero cell lines and gene expression of apoptotic genes
Authors: Sangour Maryam Hassan , Ali Iftikhar M. , Atwan Zeenah Weheed , Al Ali Ali Abd Al Lateef A. 
Published: February 2021

Abstract
Background
The newly emerged technology, nanotechnology, represents a promising solution for many medical and industrial problems. Random targeting, resistance, and side effects are the main disadvantages of the available cancer chemotherapy which are critical aspects needed to be managed. So the aim of the study was to suggest the nanoparticles as an alternative therapy for the available therapies through detecting the cytotoxic effect of Ag nanoparticles against cancer and normal cell lines and how they affect the apoptotic function and the genes involved.

Results
Ag NPs exhibited a killing rate of 40% in MCF-7 cells (the cancer cell model) at a concentration of 100 μg/ml with almost no effect on Vero cells (the normal cell model). Concerning the phenotypic apoptotic changes that were analyzed by Acridine orange and eosin and hematoxylin, Ag NPs caused the apoptosis and Vacuole degeneration as well as cell formation and the emergence of Necrotic cells in MCF-7 cells, whereas in the normal cell line Vero, no change appears in its phenotype.
Treating MCF-7 and Vero cells with Ag NPs upregulated the P53 and P21 gene expression in Vero cells, but their expression was downregulated in MCF-7 cells. PTEN was augmented in both MCF-7 and Vero cells compared to the control.

Conclusions
The AgNPs displayed selective effect in their cytotoxicity and both induced the apoptosis effect and might be suggested as a potential therapy since an increase in PTEN expression (up to 250-fold more compared to the control) due to the treatment with AgNPs augments the tumor suppressor effects of the PTEN.

Published: February 2021

Abstract
Background
Glottal insufficiency results in glottal gap between the two vocal folds, which in turn might cause dysphonia, dysphagia, and breathing problems. Vocal fold injection is considered a safe, reliable, and highly effective method of treatment.
The purpose of the present study was to assess voice outcomes and complication rates in patients with glottal insufficiency undergoing injection laryngoplasty (IL) under local versus general anesthesia before, 1 week then 1 month after IL.

Results
Examined patients were 13 males and 12 females, suffering from dysphonia due to glottal insufficiency with mean age 43.68 ± SD 14.55. Unilateral vocal fold paralysis (UVFP) was diagnosed in seventeen cases, vocal fold scarring in six cases, presbylarynx in one case, and sulcus vocalis in one case. IL was performed in 18 cases under local anesthesia, and 7 under general anesthesia. Hyaluronic acid was injection material in 23 cases and calcium hydroxylapatite in two cases. IL by either local or general anesthesia has improved the patients’ auditory perceptual analysis of voice quality as assessed by “GRBAS” scale and Voice Handicap Index (VHI). There were four (16% of all injections) minor and self-limited complications (12% under local and 4% under general anesthesia).

Conclusion
Injection laryngoplasty performed under local and general anesthesia offers similar voice outcomes, but with slightly higher self-limited complications in IL under local anesthesia.

Published: February 2021

Abstract
Background
This study aims to compare the graft uptake rate and hearing improvement of fat graft versus inlay butterfly tragal cartilage in the repair of perforations in chronic otitis media mucosal in adults.
In this retrospective study, twenty-eight patients were included with small dry anteroinferior tympanic membrane perforations (less than 1/3 of the tympanic membrane). The age range was 18 to 44 years old. Myringoplasty was done under general anesthesia for 8 patients with a fat graft (FG) and 20 patients with inlay butterfly cartilage graft (IBCG). Six months postoperatively, a follow-up evaluation was done for successful graft uptake and hearing outcomes.

Results
The success rate of graft uptake in the first group (fat graft) was 6/8 cases (75%) while in the second group (IBCG) was 19/20 (95%) with no statistically significant difference (P = 0.0148). Also, there was no statistical difference between the two groups as regards postoperative ABG, improvement changes in ABG, and number of patients with improved hearing.

Conclusions
Inlay butterfly cartilage graft is a useful graft in repairing small tympanic membrane perforations as regard graft take and hearing outcomes.

Published: February 2021

Abstract
Background
Allergy immunology specialists frequently encounter with diagnosis of migraine headache; this is a prospective study to assess the ability of the treatment of allergic rhinitis in patients having migraine to decrease the attacks of migraine.

Results
Between June 2016 and Feb. 2019, 58 patients suffer from migraine and having positive allergic symptoms for all patients. CBC with differential, nasal smear and IgE test assessment of migraine disability assessment score, and complete otorhinology examination were done pretreatment and 3 months post treatment score to know the effect of the treatment of allergic rhinitis on the attack of migraine. The mean age of patients was 40 years old. Age distribution was between 18 and 59 years old. Sex was also distributed and found 21 males and 37 females, showing more presented in females. Hemoglobin was found between 10.8 and 12.4 mg/dl, with mean 11.37 mg/dl; IgE test was between 5 and 800 IU/ml, with mean 171.29 IU/ml; no patients were included in grade I while the majority were included in grade III. We noticed that patients improved from allergic rhinitis and migranous attack at the same time had 43.1% while patients improved allergic rhinitis but migraine became less frequent and less sever were 15.52% (partially improved). Patients improved allergic rhinitis. Grade I no pain showed statistically significant difference, also grade III moderate pain showed statistically significant difference. IgE level in improved cases around 88.4.

Conclusion
There is strong relation between migraine and allergic rhinitis; the use of intranasal corticosteroid sprays and oral antihistaminic for 3 months for treatment of migraine associated with allergic rhinitis which led to decrease in the prevalence and frequency.
Old Dreams Retold

Published: February 2021

Abstract
As a champion of May Fourth enlightenment and a critic of Chinese tradition, Lu Xun is less understood as a prescient critic of the myth of science and technological rationality. Walter Benjamin invoked the utopian reconciliation of humans and nature from premodern culture in critiques of modernity. Similarly, Lu Xun conjured up images of the ancient world where rural folks lived in reciprocity with nature, worshiped supernatural beings, and observed time-honored rituals. Lu Xun linked the myth of progress and technology to a destructive chorus of “malevolent voices” by a hypocritical gentry, a technocratic elite that sought power, status, and profit in the name of enlightenment and rationality. He proclaimed that it is urgent to “rid of ourselves of this hypocrite gentry; ‘superstition’ may remain.” Invoking Benjamin's insight and affinity with Lu Xun, this article explores the Chinese writer's recovery of the mythical and ecological images from the past in the critique of modernity. Confronted with the fetishism of progress and technology in China's early modernization, Lu Xun sought to uncover and redeem primordial images from archaic traditions.
Reinventing “Nature”
Authors: Yee Winnie L. M. 
Published: February 2021

Abstract
The often-heated debates concerning Hong Kong's literary representations all take as a premise that Hong Kong has an urban identity, defined by its mythic transformation from a fishing village to a metropolis. On the return of the sovereignty to mainland China in 1997, the discourse stresses Hong Kong's exceptional status, reflecting a general anxiety that Hong Kong could be replaced by or even become just another Chinese city. This anxiety for the future is evident in an ecocritical turn, manifested in both the social realm (popular movements and organic communities) and artistic circles (independent cinema and literature). This article looks at Hong Kong literature—Wu Xubin's 吳煦斌 (1949–) stories, Dung Kai-cheung's 董啟章 (1967–) literary experiments, and a recent edited volume about plants—to determine how ecotopian imaginaries and cultural identities are closely linked to different moments in Hong Kong history. The author finds that the ecocritical turn in Hong Kong literature has opened a new space for Hong Kong's postcolonial identity.
“A New Species”
Authors: Rojas Carlos 
Published: February 2021

Abstract
Taking as its starting point Michel Foucault's use of the biological species metaphor in his claim that, in nineteenth-century Europe, “the homosexual was now a new species,” this article considers the sudden explosion of homoerotic activities and cultural representations in Greater China beginning in the late 1980s and early 1990s. The article focuses in particular on four literary works dating from around 1994 that examine queer individuals in relation modern institutional structures associated with disciplines of biology/science, reportage/media, medicine/activism, and policing/psychiatry. At the same time, however, through attention to the role played by these institutional structures in shaping new queer subjectivities, each of these four works emphasizes the subject's ability to intervene in the discursive formations within which those same subjectivities are positioned and thereby to narrativize the subject's own identity.
Looking, Reading, and Intertextuality in Ding Ling's “Shafei nüshi de riji” 莎菲女士的日記 (Miss Sophia's Diary)
Authors: Cai Keru 
Published: February 2021

Abstract
This article examines Ding Ling's 丁玲 (1904–86) practice of intertextuality in her famous 1927 story “Shafei nüshi de riji” 莎菲女士的日記 (Miss Sophia's Diary) by means of the Bakhtinian concept of dialogism. Sophia's diary is in dialogue with a plethora of texts she has read or encountered before. Ding Ling uses these intertexts to shed light on Sophia's negotiations with the New Woman's identity, as well as with the medium of the written word. At the same time, Sophia's diary is perennially in dialogue with anticipated readers or interlocutors. The story's thematization of reading is inseparable from the motifs of looking and gazing: just as Sophia is constantly preoccupied with how people look at her, she is anxious about how her diary will be read. Thus, her diary has an inherently dialogical stance as Sophia flirts with different intertextual ways of defining herself, always implicitly in contention with others who might view or read her otherwise. The article ends by reflecting on the resonances between Sophia's textual flirtations and the story's depictions of erotic desire, suggesting that the idea of promiscuity emerges as a figure for the practice of intertextuality during the May Fourth period.
