Performance Analysis of Hybrid Combining Schemes under Middleton Class-A and SαS Impulsive Noise Model
Authors: Halim Md Abdul , Majumder Satya Prasad
Published: October 2023

Impulsive noise is a significant concern for Single Input Multiple
Output (SIMO) wireless communication systems. This paper evaluates the
effectiveness of hybrid combining techniques in mitigating the impact of
impulsive noise caused by both man-made and natural phenomena. The
Selection combining-Equal Gain Combining (SC-EGC) and Selection
Combining Maximal Ratio Combining (SC-MRC) hybrid techniques are
considered in the presence of three different noise models: Additive
White Gaussian Noise (AWGN), Middleton Class-A impulsive noise model,
and Symmetric Alpha Stable (SαS) impulsive noise model for the Rayleigh
and Rician fading channels. Bit Error Rate (BER) is used to assess
channel performance. The research contribution of this paper is the
comprehensive evaluation of hybrid combining techniques in a set of
noise models that can arise in wireless communication systems, including
both man-made and natural sources of impulsive noise. The findings
suggest that impulsive noise has a greater impact on channel performance
than AWGN noise, and hybrid combining techniques are more effective in
mitigating its effects. The results have significant research
significance and practical implications for SIMO wireless communication
systems, and can guide the development of more robust and reliable
communication systems in the presence of impulsive noise.

Published: October 2023

Background/Aim: The present study aimed to develop detailed parameters
for prediction of prognosis for patients with unresectable
hepatocellular carcinoma (uHCC) receiving Atezolizumab plus Bevacizumab
(Atez/Bev). Methods: Between September 2020 and January 2023, the
patients treated with Atez/Bev were enrolled (n=719, males 577, median
age 74 years). Factors involved in overall survival (OS) were extracted
and a prognostic scoring system based on hazard ratio (HR) was created.
OS and progression-free survival (PFS) were examined retrospectively,
and the prognostic ability of the newly system was compared to CRAFITY
score using concordance index (c-index) and Akaike Information Criterion
(AIC) results. Results: Cox-hazards multivariate analysis showed BCLC
classification C/D (HR 1.4; 1 point), AFP ≥100 ng/mL (HR 1.4; 1 point),
mALBI 2a (HR 1.7; 1 point), mALBI 2b/3 (HR 2.8; 2 points), and DCP ≥100
mAU/mL (HR 1.6; 1 point) as significant factors. The assigned points
were added and used for IMnunotherapy with AFP, BCLC staging, mALBI, and
DCP evaluation (IMABALI-De) scoring. For IMABALI-De scores of
0/1/2/3/4/5, OS was not applicable (NA)/NA/26.11/18.79/14.07/8.32 months
(P<0.001; AIC 2788.67, c-index 0.699), while for CRAFITY
scores of 0/1/2, OS was 26.11/20.29/11.32 months (p<0.001; AIC
2864.54, c-index 0.606). PFS for those IMABALI-De scores was
21.75/12.89/9.18/8.0/5.0/3.75 months (P<0.001; AIC 5203.32,
c-index 0.623) and for the CRAFITY scores was10.32/7.68/3.57 months
(p<0.001; AIC 5246.61, c-index 0.574). IMABALI-De score had
better AIC and c-index results as compared to CRAFITY score for both OS
and PFS. Conclusion: The proposed IMABALI-De score may have a favorable
prognostic predictive ability for uHCC patients with Atez/Bev.

Authors: Klíčová Kateřina , Mares Jan , Sobek Ondřej , Rous Zuzana , Rous Matouš , Raška Milan , Hartung Hans-Peter
Published: October 2023

Aims: The initial phase of multiple sclerosis (MS), often known as
clinically isolated syndrome (CIS), is a critical period for identifying
individuals at high risk of progressing to full-blown MS and initiating
timely treatment. In this study, we aimed to evaluate the prognostic
value of CXCL13 and IL-8 as potential markers for CIS patients’
conversion to MS. Methods: Our study encompassed patients with CIS,
those with relapsing-remitting MS (RRMS), and control subjects, with
sample analysis conducted on both cerebrospinal fluid (CSF) and serum.
Patients were categorized into four groups: CIS-CIS (no MS development
within two years), CIS-RRMS (conversion to RRMS within two years), RRMS
(already diagnosed), and a control group (CG) with non-inflammatory CNS
disorders. Results: Results showed significantly elevated levels of
CXCL13 in CSF across all patient groups compared to the CG (p
< 0.0001, Kruskal-Wallis test). Although CXCL13 concentrations
were slightly higher in the CIS-RRMS group, statistical significance was
not reached. Similarly, significantly higher levels of IL-8 were
detected in CSF samples from all patient groups compared to the CG (p
< 0.0001, Kruskal-Wallis test), with comparable levels among
patient groups. ROC analysis in the CIS-RRMS group identified both
CXCL13 (AUC = 0.959) and IL-8 (AUC = 0.939) in CSF as significant
predictors of CIS to RRMS conversion. Conclusion: In conclusion, our
study suggests a trend toward elevated CXCL13 levels in CIS patients
progressing to RRMS. These findings emphasize the importance of
identifying prognostic markers to guide appropriate treatment strategies
for individuals in the early stages of MS.
Carbon released from drained peatlands is accelerating glacial melting in the Himalayas?
Authors: Tabasum Tanveera
Published: October 2023

Synopsis: Tanveera Tabassum Srinagar, Kashmir- India: (START) Even as a
lot of scientific capital has gone to study the impact of peatland
ecosystems on the plant and animal life and how it affects the overall
atmospherics of the earth, there is a growing sense that a lot more is
yet to be achieved in this regard. The focus of my essay is the frozen
peatlands in the Hiamalyas. The glaciers and the snow masses are rapidly
melting due to global warming. The melt down is posing a huge challenge
to the countries downhill. But as the snows are melting more and more
peatlands underneath are getting exposed resulting in the draining of
carbon dioxide in the atmosphere. The heat generated by global warming
and the release of gases from peatlands is a recipe for vicious circle
with a potential to push populations down the precipice of an imminent
disaster. My essay explains the subject in detail throwing light on its
causes and consequences and long term solutions to convert the crisis
into an opportunity. (ENDS)
Aridity and forest age mediate landscape scale patterns of tropical forest resistance to cyclonic storms
Authors: Gutierrez German Vargas , Marcano Humfredo , Ruzycki Tom , Wood Tana , Anderegg William , Powers Jennifer , Helmer Eileen
Published: October 2023

Ecological theory holds that tropical forest resistance to hurricanes
should increase with stand age and aridity. However, limited data beyond
a handful of long-term monitoring sites makes it hard to link resistance
to hurricanes with environmental gradients. We address this by using
trait data for 410 tree species, remote sensing metrics of canopy
structure, and 339 plots to assess whether forest age and aridity
mediate the impacts of two hurricanes in Puerto Rico. Hurricanes caused
a 45% and 21% decrease in forest canopy height and cover,
respectively, with a 25% increase in tree mortality. Old forest stands
in wetter regions as well as those with tall canopies dominated by low
wood density species were the most affected. Interestingly, high
resistance to hurricanes was related to enhanced drought tolerance.
These results highlight crucial complexity to include when forecasting
the fate of tropical forests to increasingly stronger hurricanes in a
changing climate.
Optimal Grid Expansion Planning in Power Systems with Surplus Generation Capacity and Suppressed Demand
Authors: NDAYISHIMIYE Vedaste , Bakkabulindi Geofrey , Miyingo Emmanuel
Published: October 2023

Abstract: In many developing countries, the construction of transmission
lines often lags behind commissioning of new power plants. This results
in insufficient transmission line capacity to evacuate generated power
to distant load centres. This study aims to address the problem of
overcapacity of installed generation relative to transmission capacity
and demand, arising from the misalignment of investments in the
respective segments. The study proposes coordinated Generation and
Transmission Expansion Planning (GTEP) models that consider surplus
generation capacity while minimizing investment and operating costs to
unlock suppressed customer demand. We develop a multistage stochastic
optimization model for GTEP, as well as isolated Generation Expansion
Planning (GEP) and Transmission Expansion Planning (TEP) models, and
then compare their performance. The models were developed and simulated
using PLEXOS Software by Energy Exemplar. The results show that the
combined GTEP model provides an optimal expansion plan that utilizes
surplus generation capacity and reduces suppressed demand by
prioritizing transmission network reinforcements and then investments in
generation. The TEP model mitigates overcapacity and unserved energy in
some areas, but if not aligned with generation planning, there will be
eventual power supply shortages as demand exceeds generation over time.
Numerical investigation of the refractive properties of near-horizontal shore platforms and their effects on harmonic and stationary wave patterns
Authors: Krier-Mariani Raphael , Wayne Stephenson , Wakes Sarah , Dickson Mark E.
Published: October 2023

Near-horizontal shore platforms display highly irregular plan shapes,
but little is known about the way in which these irregularities
influence the significant wave height (Hs) on the platforms and the
frequency components of the nearshore wave field. We use a nonlinear
Boussinesq wave model to conduct harmonic and bispectral mode
decomposition analyses, studying the control of concave and convex
platform edges over wind (WW: 0.125 - 0.33 Hz), swell (SW: 0.05 - 0.125
Hz) and infragravity (IG: 0.008 - 0.05 Hz) frequencies. For breaking and
non-breaking waves, increasing the platform edge concavity intensified
wave divergence and subsequent attenuation of SW and IG across the outer
platforms, reducing by up to 25%. Increasing the platform edge
convexity intensified focusing and amplification of SW and WW over the
outer platforms, increasing by up to 18% and 55% for breaking and
non-breaking waves. In the presence of breaking, IG amplification
depended on the generation of wave divergence across the inner platform,
a condition determined by a critical convex curvature threshold (Κ=1.8)
balancing wave focusing from refraction and defocusing from breaking. We
find that convex curvature can determine the relative dominance of WW,
SW and IG across platforms. Alongshore, coherent wave interactions
governed IG stationary patterns defined by a node near the platform
centreline and two antinodes on either side of concave edges. A node was
generated at the platform centreline, and two antinodes were observed on
either side of the convex edges for Κ>1.8, with the
opposite pattern observed for Κ<1.8.

Published: October 2023

OBJECTIVE

We sought to study the associations between plasma metabolites in the tryptophan-kynurenine pathway and the risk of progression to end-stage kidney disease (ESKD) in patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS

Plasma tryptophan, kynurenine, 3-hydroxykynurenine, kynurenic acid, and xanthurenic acid concentrations were measured in discovery (n = 1,915) and replication (n = 346) cohorts. External validation was performed in Chronic Renal Insufficiency Cohort (CRIC) participants with diabetes (n = 1,312). The primary outcome was a composite of incident ESKD (progression to estimated glomerular filtration rate [eGFR] <15 mL/min/1.73 m2, sustained dialysis, or renal death). The secondary outcome was annual eGFR decline.

RESULTS

In the discovery cohort, tryptophan was inversely associated with risk for ESKD, and kynurenine-to-tryptophan ratio (KTR) was positively associated with risk for ESKD after adjustment for clinical risk factors, including baseline eGFR and albuminuria (adjusted hazard ratios [HRs] 0.62 [95% CI 0.51, 0.75] and 1.48 [1.20, 1.84] per 1 SD). High levels of kynurenic acid and xanthurenic acid were associated with low risks of ESKD (0.74 [0.60, 0.91] and 0.74 [0.60, 0.91]). Consistently, high levels of tryptophan, kynurenic acid, and xanthurenic acid were independently associated with a slower eGFR decline, while a high KTR was predictive of a faster eGFR decline. Similar outcomes were obtained in the replication cohort. Furthermore, the inverse association between kynurenic acid and risk of ESKD was externally validated in CRIC participants with diabetes (adjusted HR 0.78 [0.65, 0.93]).

CONCLUSIONS

Accelerated catabolism of tryptophan in the kynurenine pathway may be involved in progressive loss of kidney function. However, shunting the kynurenine pathway toward the kynurenic acid branch may potentially slow renal progression.

Published: October 2023

En la actualidad, la productividad es una herramienta esencial en las organizaciones, la cual se logra con la mejora de procesos mediante el uso de diversas herramientas, filosofías y metodologías de la ingeniería disponibles de manera abierta. La falta de productividad trae como consecuencia pérdidas que repercuten en altos costos, escasos ingresos y, por ende, pocas o nulas utilidades. Existen técnicas que pueden ser empleadas por micro y pequeñas empresas para aprovechar mejor los recursos con los que se cuenta. Por eso, en este trabajo se propone el uso de herramientas de manufactura esbelta o lean manufacturing tales como 5’S, diagrama de spaghetti, tableros kanban, entre otras, para optimizar los procesos en un laboratorio de mecánica de suelos, donde se analiza la calidad de diversos materiales utilizados en la construcción. Durante la implementación de las herramientas se realizó la redistribución de elementos de trabajo y se mejoró el control de los procesos. Como resultado se obtuvo una reducción del 44.88 % en los movimientos requeridos por el personal para ejecutar diversas actividades y se liberó el 32.37 % del área de trabajo que se encontraba desaprovechada, lo que permitió realizar trabajos de forma paralela, mejor el flujo laboral y disminuir la cantidad de muestras en espera. Al implementar tableros kanban se consiguió un control y organización que facilitan el seguimiento de los procesos por parte del jefe de laboratorio y el personal, lo que sirve para realizar las actividades de forma ordenada.

Published: October 2023

Este trabalho tem como objetivo analisar as estratégias persuasivas presentes em dois pronunciamentos do pastor Silas Malafaia, por meio de postagens em seu perfil da rede social facebook. O citado pastor evangélico, líder e fundador da Igreja Assembleia de Deus Vitória em Cristo (ADVEC), utiliza estratégias argumentativas que engatilham a ordem do dissenso, presente na modalidade argumentativa polêmica, para categorizar, recategorizar e desqualificar os ministros e as ministras do Supremo Tribunal Federal (STF), em especial o ministro Alexandre de Moraes, acusando-o de abuso de autoridade, no que concerne ao caso do mandado de prisão contra o deputado federal Daniel Silveira, por este perpetuar ideias contra o Estado Democrático de Direito em suas redes sociais. Para dar cumprimento ao nosso objetivo, utilizamos a Teoria da Argumentação no Discurso (AMOSSY, 2020), enfatizando a modalidade polêmica (AMOSSY, 2017). Os resultados apontam que Silas Malafaia utiliza estratégias persuasivas forjadas pelo ethos, logos e pathos no campo da polêmica. Além disso, o discurso desse chefe religioso mostra as características da citada modalidade, a saber: choque antagônico entre teses, polarização social e desqualificação do outro.
CIDADE DE BISSAU EM NO FUNDO DO CANTO, DE ODETE SEMEDO
Authors: Lima da Silva Canja Antonia Edivânia
Published: October 2023

O presente trabalho tem por objetivo analisar seis poemas da obra No Fundo do Canto (2007) da poeta guineense Odete Semedo, intitulados “O teu mensageiro”, “O prenúncio dos trezentos e trinta e três dias”, “Quando tudo começou Bissau não quis acreditar”, “Perdidos, desnorteados”, “Bissau é um enigma”. O livro pode ser entendido como um épico da contemporaneidade, constituído pela voz feminina que apresenta diversas falas que compõe sua poesia. A pesquisa foi realizada em fontes bibliográficas e fundamenta-se na leitura crítica dos textos de Moema Parente Augel “Cantopoema do desassossego” (2003), posfácio ao livro No Fundo do Canto, e O Desafio do Escombro: nação, identidade e pós- colonialismo na literatura da Guiné Bissau (2007), no trabalho de Monaliza Rios Silva A Guiné-Bissau No Fundo do Canto: O épico identitário de Odete Semedo (2010), na tese de doutorado da própria Maria Odete da Costa Soares Semedo As Mandjuandadi: cantigas de mulher na Guiné-Bissau: da tradição oral à literatura (2010) e estudos recentes sobre cidade através da obra Todas as cidades, a cidade (2008), de Renato Cordeiro Gomes. De modo geral, percebe-se que, na poesia de No Fundo do Canto, a voz lírica está voltada ao sentimento de como o país é apresentado e visto por seus filhos como terra fecunda e acolhedora remetendo-a a figura da mulher na sua capacidade de gerar e acolher uma nova vida dentro do seu ventre. Nesta perspectiva, Bissau é descrita como a terra que acolhe, protege e luta para que os seus não estejam desamparados e sozinhos diante do conflito militar armado que se levanta dentro da nação guineense.
A TRAJETÓRIA DA LITERATURA DE CORDEL NO BRASIL:

Published: October 2023

Este artigo apresenta uma perspectiva histórica: Como surgiu a literatura de cordel, sua forma cantada, produzida em papéis dobrados para ser vendida em barbantes nas feiras do Nordeste, tratamos das características desse gênero, suas temáticas, versos e formas de composição, bem como do valor dessa literatura em nossa cultura. A intensão desta pesquisa é verificar a evolução cronológica do cordel e analisar a expansão desse gênero literário na contemporaneidade. A hipótese apresentada é que, poesia de cordel, até há pouco tempo, restringia-se ao público do nordeste, cenário que se modificou com a publicação das obras de Bráulio Bessa, tanto no formato impresso como nos formatos televisivo e digital. Contudo, lançamos um olhar a esses veículos de comunicação contemporâneos, que promoveram modificações significativas no tipo de público e na forma de recepção do cordel.

Animal welfare relates to physical and mental states that conform to the natural behavior of animals and need to be implemented to protect animals. Laying hens are very vulnerable to violating animal welfare principles because of high production targets but demands to minimize costs. The study was conducted in the laying hens of the grower phase of PT. ITS with direct observations, interviews, and discussions. The results were analyzed descriptively according to five principles of animal welfare, namely freedom from pain, injury, and disease, freedom from hunger and thirst, freedom from heat and discomfort, freedom from fear and suffering, and freedom to express normal and natural behavior. The results show that the implementation of animal welfare at PT. ITS has been carried out, but there are also aspects that are not fulfilled, namely the aspect of being free to express normal and natural behavior that has not been fully implemented because the density of the rang or cage makes the animals very crowded so this must be corrected so that the livestock welfare aspects can be met.
