Modification of Major Intersections in Urban Area of Sialkot City, Pakistan

Mehran University Research Journal of Engineering and Technology, 2022
Traffic management is a major problem in large cities of Pakistan. Pakistan is a developing country with aging infrastructure of roadways and railways. The traffic conditions are deteriorating due to inappropriate design. Traffic problems due to improper

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Design and Analysis of a General Relay-Node Selection Mechanism on Intersection in Vehicular Networks

Sensors, 2018
Employment of a relay node can extend the coverage of a message in vehicular networks (VNET). In addition, the prior information regarding the road structure, which determines the structure of VNET, can benefit relay-node selection. However, the non-line-

On purifiable subgroups and the intersection problem [PDF]

Pacific Journal of Mathematics, 1993
\textit{L. Fuchs} posed the problem of characterizing the subgroups of arbitrary abelian groups which are intersections of finitely many pure subgroups [Infinite Abelian Groups, Vol. I (1970; Zbl 0209.055); Problem 13]. We show that this problem for purifiable subgroups of abelian \(p\)- groups can be reduced to the case where the subgroups are ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Local and global lifted cover inequalities for the 0-1 multidimensional knapsack problem [PDF]

, 2007
The 0-1 Multidimensional Knapsack Problem (0-1 MKP) is a well- known (and strongly N P -hard) combinatorial optimization problem with many applications.

The Intersection Problem for Finite Monoids

CoRR, 2017
We investigate the intersection problem for finite monoids, which asks for a given set of regular languages, represented by recognizing morphisms to finite monoids from a variety V, whether there exists a word contained in their intersection. Our main result is that the problem is PSPACE-complete if V is contained in DS and NP-complete if V is non ...

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

An intersection problem for finite automata

Discrete Applied Mathematics, 1988
Let M(A,S) be the set of all initial finite automata with state space S of k states and alphabet A of n letters and f: M(A,S)\(\to S\). The language accepted by \(M\in M(A,S)\) and f is the set of words in A mapping the initial state of M to f(M). A map f satisfies the m-intersection condition if for any m machines in M(A,S) there is a word accepted by
