Abstract
Pythagorean cubic fuzzy sets represent an advancement beyond conventional interval-valued Pythagorean sets, integrating the principles of Pythagorean fuzzy sets and interval-valued Pythagorean fuzzy sets. Given the critical significance of distance measures in real-world decision-making and pattern recognition tasks, it is noteworthy that there exists a notable gap in the literature regarding distance measures specifically tailored for Pythagorean cubic fuzzy sets. The objectives of this paper are:•To define novel generalized distance measures between Pythagorean cubic fuzzy sets (PCFSs) to tackle intricate decision-making challenges.•These novel distance measures are undergoing testing on a real-world scenario concerning the management of anxiety and depression to evaluate their effectiveness and practical application.•We have illustrated the boundedness and nonlinear characteristics inherent in these distance measures. In addition, we conduct comparative analyses with existing approaches to validate the proposed methodology, thereby providing insights into its advantages and potential applications.

Abstract
The concept of p , q - quasirung orthopair fuzzy (p , q - QOF) sets is an advanced extension of q - rung orthopair fuzzy sets (q - ROFSs). This paper introduces the adaptation of Hamacher t-norm and t-conorm to the p , q - QOF environment. A series of Hamacher aggregation operators (AOs) and their associated properties are presented. This study extends its application to multi-criteria group decision-making (MCGDM) for practical problem-solving, illustrated through the analysis of mobile payment platforms. The influence of the aggregation operator parameters, denoted as p and q , on the outcomes of decisions is effectively showcased. Moreover, a comparative analysis is carried out to validate the credibility and authenticity of the proposed model. Finally, the advantages and limitations of the proposed model are outlined.

Abstract
OBJECTIVE To evaluate dermatoscopic features of cutaneous leishmaniasis and to compare its diagnostic accuracy against slit skin smear and skin histopathology. METHODS This cross-sectional study was conducted at the Department of Dermatology, Pakistan Navy Station (PNS) Shifa Hospital, Karachi, Pakistan, from August 2021 to August 2022. A total of 200 lesions from 70 patients of cutaneous leishmaniasis diagnosed with slit skin smear for Leishmania-Donovan (LD) bodies and skin biopsy were included via non-probability consecutive sampling technique. Dermatoscopic evaluation was performed via a handheld dermatoscope (DELTA 20T; HEINE, Gilching, Germany) on 10x magnification. All dermatoscopic images were analyzed by two different observers who had command of dermatoscopy. Data analysis was done using Statistical Package for the Social Sciences SPSS version 27 (IBM Corp., Armonk, NY, USA). RESULTS Common dermatoscopic findings were erythema 200 (100%), hyperkeratosis 140 (70%), crusting 50 (25%), ulceration 42 (21%), milia-like structure 58 (29%), tear drop-like structure 46 (23%), yellow tears 70 (35%), and white starburst pattern 68 (34%). Less common findings were yellow hue 28 (14%), orange areas 26 (13%) and scar seven (3.5%). Vascular structures frequently observed were linear vessels 109 (54.5%), dotted vessels 80 (40%), and hairpin vessels 61 (30.5%); less common findings were comma-shaped vessels 52 (26%), arborizing vessels 20 (10%), crown vessels nine (4.5%). Comparison of dermatoscopic features was done with slit skin smear for LD bodies (p value = 0.003 ) and histopathology (p value = 0.001). CONCLUSIONS Dermatoscopy is a non-invasive technique that is helpful in diagnosing cutaneous leishmaniasis, saving time in making rapid diagnosis and saving the need to undergo extensive invasive investigation. Yield of dermatoscopy was comparable to slit smear for LD bodies and histopathology and was found to be effective in making rapid diagnosis with significant accuracy (p value <0.05).

Abstract
AbstractCubic Pythagorean fuzzy (CPF) set (CPFS) is a hybrid set that can hold much more information and can be used to describe both an interval-valued Pythagorean fuzzy set (IVPFS) and Pythagorean fuzzy set (PFS) at the same time to handle data uncertainties. Based on it, the present study is classified into three phases. The first phase is to modify the existing operational laws and aggregation operators (AOs) in the article presented by Abbas et al. (Journal of Intelligent & Fuzzy Systems, vol. 37, no. 1, pp. 1529–1544, (2019)). The main objective of improved operational laws is to eliminate the flows and ambiguities in existing AOs. Secondly, based on these laws, various AOs to aggregate the information are acquired along with their requisite properties and relations. Lastly, an approach for interpreting the multi-attribute decision-making (MCDM) problem based on the stated operators is given and illustrated with an example. Some of the existing models are used to perform a comprehensive comparative analysis to demonstrate their impacts.

Abstract
We will present the design, growth, fabrication, electronic control and packaging of the InAs/InP quantum dot (QD) multi-wavelength lasers (MWLs) developed by AEP of NRC in Canada. Their key technical specifications include L-I-V curves, optical and RF beating spectra, relative intensity noise (RIN), and optical phase noise of each individual wavelength channel, as well as timing jitter are investigated. Data bandwidth transmission capacity of 5.376 Tbit/s and 10.3 Tbit/s respectively in the PAM-4 and 16-QAM modulation formats are demonstrated by only using a single QD MWL chip. We have also developed a novel monolithic InAs/InP QD dual-wavelength (DW) DFB laser as a compact optical beat source to generate millimeter-wave (MMW) signals. Because of using a common cavity, highly coherent and correlated optical modes with optical linewidth as low as 15.83 kHz, spectrally pure MMW signals around 46.8 GHz with a linewidth down to 26.1 kHz were experimentally demonstrated. By using this QD DW-DFB laser, a 1Gbaud (2Gbps) MMW over-fiber transmission link is demonstrated with PAM-4 signals. The results show that the demonstrated device is suitable for high speed high capacity MMW fiber-wireless integrated fronthaul of 5G networks.

Abstract
The disease early warning system (DEWS) was introduced in the immediate aftermath of the 2005 earthquake in Pakistan, with the objective to undertake prompt investigation and mitigation of disease outbreaks. The DEWS network was replicated successfully during subsequent flood and earthquake disasters as well as during the 2008-09 internally displaced persons' crisis. DEWS-generated alerts, prompt investigations and timely responses had an effective contribution to the control of epidemics. Through DEWS, 1360 reported alerts during 2005-09 averted the risk of disease outbreaks through pre-emptive necessary measures, while the 187 confirmed outbreaks were effectively controlled. In the aftermath of the disasters, DEWS technology also facilitated the development of a disease-surveillance system that became an integral part of the district health system. This study aims to report the DEWS success and substantiate its lead role as a priority emergency health response intervention.

Abstract
Mid-infrared vertical external cavity surface emitting lasers (VECSELs) for 5 microm in wavelength have been realized. The active parts are of a simple structure, either a 2 microm thick PbTe gain layer or two 150 nm PbTe layers embedded in Pb(1-x)Eu(x)Te barriers. Epitaxial 2.5 pair Pb(1-y)Eu(y)Te/BaF(2) Bragg mirrors are employed to form the cavity, and an Al layer is deposited for improved heat dissipation. Emission up to 300 mW(p) is observed with microsecond pulses or 3 mW cw at 100 K is obtained. Quantum efficiency is up to 14%, and lasing occurs up to 175 K when pumped with a 1.55 microm wavelength pump laser.

Abstract
Sensitizing health providers to customers' needs and women's health remains a challenge to the Pakistani health system. The Health Workers for Change methodology has been demonstrated to improve provider-client relationships in certain African and Latin American countries. This paper describes the experience of using Health Workers for Change participatory workshops in Pakistan to sensitize male and female health providers to gender issues. Health care providers identified the unmet needs of women clients as a function of individual, household and societal factors, and, unlike the African experience with this tool, not predominantly confined to factors associated with the health facility.

Abstract
Thirty-nine patients with a clinical diagnosis of palmoplantar psoriasis [23 (58%) males and 16 (42%) females] were included in this study with the aim of evaluating the efficacy of occlusive calcipotriol 50 micrograms/mg ointment vs. nonocclusive therapy. Patients were randomized to either twice-weekly overnight calcipotriol ointment under occlusion or twice-daily topical nonocclusive application of the same ointment for 6 weeks. The effect of treatment was assessed on the basis of a psoriasis signs score for erythema, thickness and scaliness, which was graded from 0 (absent) to 4 (most severe) at the first visit, after 2 weeks and at the end of treatment. Analysis of our results showed that twice-weekly occlusive calcipotriol ointment was as effective as the twice-daily application. The mean total score at baseline was 6 for the occlusive group and 6.1 for the nonocclusive group. The score decreased to 1.5 in both groups at the end of treatment. No significant adverse effects were reported by patients or investigators. We conclude that occlusive calcipotriol ointment is effective in the treatment of palmoplantar psoriasis and may produce even better results with more frequent use, such as application on alternate days.

Abstract
Forty-two patients aged between 6 and 61 years (mean: 33.5 years) with psoriasis of the scalp were enrolled in this study. Twenty-seven patients (69%) were males and 15 (31%) were females. The aim of our study was to evaluate the efficacy, safety and tolerability of topical calcipotriol 50 micrograms/g/ml solution vs. betamethasone valerate 1% lotion in the treatment of psoriasis of the scalp. The study was randomized with the twice-daily application of either calcipotriol solution or betamethasone valerate lotion for 6 weeks. Treatment evaluation was clinically based on signs of psoriasis (thickness, redness, scaliness) which were scored from 0 = absent to 4 = severest possible involvement and was performed at the start of treatment and at weeks 2 and 6 of treatment. The results showed a marked improvement and clearance at the end of treatment in 15 (72.8%) of the 24 patients in the calcipotriol group and in 13 of the 18 patients (72%) in the betamethasone group. The mean total sign score at baseline was 5.1 in the calcipotriol group and 5.4 in the betamethasone valerate group. At the end of treatment, this score was decreased to 2.1 and 1.49, respectively. No significant adverse effects were reported in either group except in two patients (8.3%) in the calcipotriol group who developed signs of irritation including itching and erythema. In conclusion, both drugs were effective and well tolerated in the treatment of scalp psoriasis but in some patients calcipotriol had to be given for more prolonged courses.

Abstract
BACKGROUND Leber's congenital amaurosis (LCA) represents the earliest and severest form of retinal dystrophy leading to congenital blindness. A total of 20% of children attending blind schools have this disease. LCA has a multigenic basis and is proving central to our understanding of the development of the retina. We describe the clinical and molecular genetic features of four inbred pedigrees from neighbouring remote villages in northern Pakistan, in which some of the affected members have concurrent keratoconus. METHODS History-taking and physical and eye examinations were performed in the field. Venipuncture, DNA extraction, studies of linkage to known LCA genes, automated sequencing and polymorphism analyses for haplotype assessments were done. RESULTS We examined 12 affected and 15 unaffected family members. By history, there were an additional nine blind people in the four pedigrees. In each pedigree a consanguineous marriage was evident. We found a homozygous nonsense mutation in the AIPL1 gene, which replaces a tryptophan with a stop codon (Trp278X). The phenotype is severe and variable, despite the common molecular genetic etiology in each family. Affected patients had hand motion to no light perception vision and fundus findings ranging from maculopathy to diffuse pigmentary retinopathy. Three affected members had definite keratoconus, and two were suspects based on mild cone formation in the cornea of at least one eye. INTERPRETATION We have identified four Pakistani families with a severe form of LCA that is associated with severe keratoconus in some affected members. The molecular etiology in all four families is a homozygous nonsense mutation, Trp278X, in the photoreceptor-pineal gene AIPL1. To our knowledge, this is one of the first phenotype-genotype correlations of AIPL1-associated LCA.

Abstract
The quantitative subcellular distribution of the fatty acid binding protein (FABP) in heart muscle is reported for the first time. A gradient-like distribution according to the following pattern was observed: 6.96 mg X mL-1 on the myofibrils, 2.77 mg X mL-1 in the spaces surrounding the mitochondria, and 2.21 mg X mL-1 in the mitochondria. This heterogeneous distribution suggests that the local in vivo concentration of FABP might fluctuate as a function of time. The consequences of these possible fluctuations, particularly in the mitochondrial vicinity, were analyzed in an in vitro system containing a fixed concentration of cardiac mitochondria and stearic acid but variable concentrations of FABP. Competition for the fatty acid was observed between the mitochondrial membranes and the binding sites on the protein. Maximal binding of fatty acid to FABP was detected in the range of FABP concentration between 1 and 3 mg X mL-1. Remarkably, in this concentration range, two emerging peaks of beta-oxidative activity were also detected. As a major conclusion, it appears that the fatty acid pool, bound to FABP, is the source of fatty acid providing the beta-oxidative system with substrate. The mechanism of fatty acid transfer from this pool toward the beta-oxidative system remains an open question. However, it is suggested that a gradient-like distribution of FABP in the mitochondrial vicinity leads to the coexistence of multispecies of the protein by self-aggregation. Only two of these species seem to be involved in this fatty acid transfer. As a consequence, a strong modulation of fatty acid beta-oxidation rate is observed in isolated mitochondria when the concentrations of these two species are allowed to fluctuate. In conclusion, this unique cardiac fatty acid carrier, via its self-aggregation capacity and its in vivo gradient-like distribution, may act as a powerful effector in the regulation of heart energy.
